FIG. 1 is a schematic diagram of a battery and a fixture according to some embodiments of the present disclosure. In some embodiments, the fixture 100 may be used to secure the battery 200. In some embodiments, referring to fig. 1, the battery 200 may include a plurality of mounting holes through which the fixing device 100 may detachably fix the battery 200 to the electric vehicle. In some embodiments, a plurality of mounting holes may be provided in one battery 200, and accordingly, a plurality of fixing devices 100 may fix the battery 200 through the plurality of mounting holes. In some embodiments, a plurality of fixing devices 100 may be respectively disposed at edges of the battery 200. For example, for the rectangular parallelepiped battery 200, 4 mounting holes may be provided at four corner edges of the bottom surface of the rectangular parallelepiped battery 200, and the 4 fixing devices 100 fix the battery 200 on the electric vehicle through the mounting holes of the rectangular parallelepiped battery 200. In some embodiments, a plurality of (e.g., 3, 4, etc.) mounting holes may be provided on each side of the rectangular parallelepiped battery 200, and each mounting hole is fixed by the fixing device 100. Thus, the plurality of fixing devices 100 are used for fixing, so that the stability of installing the battery 200 can be improved, and the battery 200 is prevented from falling off due to the damage of one fixing device 100.

FIG. 2 is a schematic diagram of a fixture 100 according to some embodiments herein. In some embodiments, referring to fig. 2, the fixing device 100 may include a locking member 110, a snap member 120, and an operating member 130. The operating member 130 is movably connected to the latch 120, and the operating member 130 is operable to move from the first position 160 to the second position 170, thereby moving the latch 120 from the locked position to the unlocked position. In some embodiments, the movable connection may be a connection in which relative movement of the two structures may occur. For example, the movable connection may be a hinge connection, that is, the operating member 130 and the latch member 120 are hinged to each other, and the latch member 120 can rotate relative to the operating member 130. For another example, the movable connection may be a sliding connection, that is, the clamping member 120 can slide relative to the operating member 130. The operating member 130 and the clamping member 120 can move relatively but not be separated from each other by other movable connection methods.

In some embodiments, the operating member 130 has a plurality of operating positions relative to the locking member 110, and the operating member 130 is movable between a plurality of positions relative to the locking member 110. In some embodiments, the plurality of operating positions can include a first position 160 and a second position 170, and the operating member 130 can be moved relative to the locking member 110 between the first position 160 and the second position 170. In some embodiments, since the operating member 130 is movably connected to the latch 120, when the operating member 130 moves between the first position 160 and the second position 170 relative to the locking member 110, the operating member 130 can move the latch 120 between the locking position and the unlocking position. In some embodiments, the first position 160 and the second position 170 can be configured according to the specific structure of the operation member 130 and the clip member 120, and more details about the first position 160 and the second position 170 can be found in the related description of fig. 6A and 6B. In some embodiments, the locking position may be a position where the snap 120 is engaged with the locking member 110. In some embodiments, the unlocked position may be a position in which the snap member 120 is separated from the locking member 120.

Fig. 3 is a schematic diagram of the structure of the locking element 110 according to some embodiments herein. In some embodiments, the locking member 110 can be a component that provides a locking support that can provide support for the snap member 120 when mated with the snap member 120 to keep the locking member 110 and the snap member 120 relatively locked. In some embodiments, as shown in FIG. 3, the locking element 110 may be an axially extending locking bar, the locking element 110 having a first end 111 and a second end 112 in the axial direction. In some embodiments, the first end 111 of the locking member 110 may be coupled to an electric vehicle (e.g., a chassis). The second end 112 of the locking member 110 can engage the snap member 120. In some embodiments, the cross-section of the locking bar may be circular, triangular, quadrilateral, etc. Correspondingly, the locking bar may have a cylindrical shape, a triangular prism shape, a quadrangular prism shape, etc. In some embodiments, the lock 100 may be a wear resistant material, for example, the material of the lock 100 may include one or more of a metallic material (copper, aluminum, chromium, titanium, gold, etc.), a metallic alloy (copper aluminum alloy, copper gold alloy, titanium alloy, aluminum alloy, etc.).

In some embodiments, the locking member 110 may include a locking portion, which may be disposed at the second end 112 of the locking member 110. The locking portion may be a portion or a structure that provides locking by cooperating with the snap-fit portion on the snap-fit member 110. In some embodiments, as shown in fig. 3, the locking portion may be a groove, a protrusion, a hole, or the like in the locking member 110 perpendicular to the axis of the locking member 110. For example, when the locking portion is a groove in the locking member 110, a corresponding protrusion may be provided on the clamping member 110, and the locking member 110 and the clamping member 120 are locked relatively on the axis by inserting the protrusion into the groove, so that the locking member 110 and the clamping member 120 are matched; the separation of the locking member 110 and the catching member 120 is achieved by moving the protrusion out of the groove so that the locking member 110 and the catching member 120 can move relatively on the axis. In some embodiments, the locking portion may also be a protrusion, and the clip 120 may be provided with a corresponding groove for matching.

In some embodiments, the locking member 110 may be secured to the electric vehicle. In order to replace the battery 200, the battery 200 can be sleeved on the locking member 110, and then the clamping member 120 is matched with the locking member 110, so that the clamping member 120 and the locking member 110 are in a relative locking state, the battery 200 and the locking member 110 can be kept in a relative locking state, that is, the battery 200 is locked on the electric vehicle, and the battery 200 is fixed.

In some embodiments, the locking element 110 may comprise a locking cap. In some embodiments, a locking cap may be disposed at the first end 111 of the locking member. In some embodiments, the locking cap may have a cross-section larger than the mounting hole of the battery 200, which serves to prevent the battery 200 from moving axially along one end of the locking portion. Thus, the locking cap can be matched with the fixed clamping piece 120 to ensure that the battery 200 cannot axially move, and the fixing effect of the battery 200 is improved. In some embodiments, the locking cap may be circular, rectangular, hexagonal, etc., and will not be described herein.

In some embodiments, one end of the locking cap may be secured to the electric vehicle. In some embodiments, when the fixing device 100 fixes the battery 200, the other end of the locking cap may contact the battery 200 sleeved on the locking member 110. Through the cooperation of joint spare 120 and locking piece 110 to and the limiting displacement of locking cap to battery 200, can make battery 200 can not follow the axial of locking piece and shift out the first end 111 of locking piece, thereby make battery 200 and locking piece 110 keep relative locking, and also keep relative locking with the electric motor car, realize battery 200's fixed. Through setting up the locking cap, can make battery 200 unable along the axial displacement of locking piece to contact with the electric motor car to make and keep certain clearance between electric motor car and the battery 200, do benefit to the heat dissipation of battery 200, also can prevent simultaneously that wearing and tearing from producing because of friction or collision between battery 200 and the electric motor car.

In some embodiments, the locking member 110 may not be provided with a locking cap, one end of the battery 200 sleeved on the locking member 110 is in contact with the electric vehicle, the battery 200 is prevented from moving out of the first end 111 of the locking portion by the electric vehicle, and the other end of the battery 200 is prevented from moving out of the second end of the locking portion by the cooperation of the locking member 110 and the clamping member 120, so as to fix the battery 200.

In some embodiments, the fastening device 100 may further include a bumper pad that is sleeved over the locking member. In some embodiments, when the fixing device 100 fixes the battery 200, the buffer spacer is located between the battery 200 and the lock cap to provide buffer protection for the battery 200 and the lock cap. In some embodiments, in the case that the locking member 110 is not provided with a locking cap, a buffer gasket may be sleeved on the locking member, and the buffer gasket is located between the battery 200 and the electric vehicle when the fixing device 100 fixes the battery 200. In this manner, the bumper may mitigate slight axial movement of the battery 200 during movement of the electric vehicle, reducing friction and impact between the battery 200 and other components.

In some embodiments, the cushion pad may be fixedly coupled to the locking cap such that the cushion pad is integrally coupled to the locking member 110. In some embodiments, when the cushion pad is in contact or connected with the locking cap, an edge of the locking cap is located inward of an edge of the cushion pad on the contact or connection face. In some embodiments, the cushion pieces may be in the shape of a circular ring, a rectangular ring, a hexagonal ring, or the like. The shape of the buffer pad can also correspond to the shape of the lock cap, and if the lock cap is circular, the buffer pad can be a circular ring. For example, the locking cap may be a circular structure and the bumper may be a circular structure having a diameter greater than the locking cap. In some embodiments, the shape of the bumper pad may not correspond to the shape of the locking cap. For example, the locking cap may be a hexagonal structure and the bumper may be a circular structure (e.g., a circumscribed circle of a hexagon) that completely covers the locking cap. In some embodiments, the cushion pieces may not be fixed to the locking cap, but only contact the locking cap.

In some embodiments, the cushion sheet may be a pad of flexible material that may cushion the battery 200 from slight axial movement during movement of the electric vehicle, thereby reducing friction and impact between the battery 200 and the locking cap. In some embodiments, the cushion pad may be a flexible material such as sponge, rubber, silicone, or the like. In some embodiments, the hardness of the cushion pad may be related to the weight of the device to be fixed, and the higher the weight, the greater the hardness of the cushion pad required, thereby achieving better cushioning effect. For example, the hardness of the bumper pad may be 50-60 degrees shore. So, buffer pad and lock cap laminating design and buffer pad's edge are greater than the lock cap edge, can avoid the contact of battery 200 and lock cap, further reduce the friction or the collision between the higher structures of hardness such as battery 200 and electric motor car or lock cap, avoid battery 200 to damage.

Fig. 4 is a schematic structural view of the clip 120 according to some embodiments of the present disclosure. In some embodiments, the latch 120 may be a component that functions as a position limitation when engaged with the locking member. In some embodiments, the latch may switch the assembly of the locking state and the unlocking state of the fixing device 100, which may remain locked relative to the locking member 110 when engaged with the locking member 110. In some embodiments, when the clamping member 120 moves relative to the locking member 110 in a direction perpendicular to the axis of the locking member 110, the clamping member 120 and the locking member 110 can be separated from each other, so that the clamping member 120 and the locking member 110 are disengaged. In some embodiments, the clip 120 can be a structure that can be sleeved or surrounded on the locking member 110. When the locking member 110 is engaged with the snap member 120, the snap member 120 may restrict the battery 200 from moving along one end axis of the locking portion. In some embodiments, the radius of the lower end (the end near the first location 160) of the snap-in member may be greater than the radius of the upper end (the end near the second location 170). In some embodiments, the sides of the snap-in member transition smoothly from top to bottom. In some embodiments, the side-spreading shape of the clip 120 can be curved or flat. In some embodiments, the snap member 120 may be in the shape of a hollow cylinder, a hollow prism, or a hollow cone. As shown in fig. 4, the clamping member 120 may be a hollow cone composed of two half-cones. The shape of the inner side surface of the clamping member 120 can correspond to the shape of the outer side surface of the locking member 110, so that the locking member 110 and the clamping member 120 can be attached when being matched. For example, the outer side surface of the locking member 110 is cylindrical, and the engaging member 120 may have a hollow shape having a cylindrical inner side surface. In some embodiments, the clip 120 may be made of a wear-resistant material, for example, the material of the clip 120 may include one or more of a metal material (copper, aluminum, chromium, titanium, gold, etc.), a metal alloy (copper-aluminum alloy, copper-gold alloy, titanium alloy, aluminum alloy, etc.), and this specification does not limit this to any particular limitation.

In some embodiments, the clip 120 may include a clip portion 121, which may be disposed on an inner wall of the clip 120. The catching portion 121 may be a component or structure of the catching member 120 for cooperating with the locking portion to switch the locking state and the unlocking state. In some embodiments, the snap-in portion 121 may receive the load of the battery 200 by cooperating with the locking portion and prevent the battery 200 from moving out of the locking member from the second end, thereby achieving the fixation of the battery 200. In some embodiments, as shown in fig. 4, the clamping portion 121 may be a groove, a boss, a hole or the like in the clamping member 120 perpendicular to the central axis of the clamping member 120. In some embodiments, the shape of the snap-in portion 121 may correspond to the shape of the locking portion. For example, if the locking portion is a groove, the shape of the clamping portion 121 may be a boss, when the fixing device 100 is in the locking state, the boss of the clamping portion 121 may be inserted into the groove of the locking portion to achieve locking, and when the fixing device 100 is in the unlocking state, the boss of the clamping portion 121 may be withdrawn from the groove of the locking portion to achieve unlocking. For another example, if the locking portion is a boss, the shape of the snap-in portion 121 may be a groove, which can achieve locking and unlocking similarly. The specific implementation manner of the matching of the locking portion and the clamping portion 121 can refer to the related description in other places of the specification, and is not described herein again.

In some embodiments, the locking position and the unlocking position of the snap member 120 are related to the positions of the locking portion and the snap portion 121. When the catching portion 121 (e.g., a protrusion) is completely inserted into the locking portion (e.g., a recess), the catching piece 120 is in the locking position; when the catching portion 121 (e.g., a protrusion) is completely withdrawn from the locking portion (e.g., a recess), the catching member 120 is in the unlocking position. When the clamping piece is in the locking position, the fixing device 100 is in the locking state; when the clip is in the unlocked position, the fixing device 100 is in the unlocked state. The locking state may be a state in which the catching member 120 and the locking member 110 cannot be separated from each other in the axial direction of the locking member 110. The unlocked state may be a state in which the snap member 120 and the locking member 110 can be separated from each other in the axial direction of the locking member 110. For example, the locked state may indicate that the engaging members 120 and the locking members 110 of the fixing device 100 have been completely engaged with each other and the battery 200 can be fixed, whereas the unlocked state may indicate that the engaging members 120 and the locking members 110 of the fixing device 100 have been released from the engagement with each other and the fixing device 100 and the battery can be unloaded.

In some embodiments, the latch 120 can include at least one locking clip that can move relative to the operating member 130 in a direction perpendicular to the axis of the operating member 130 to move the latch 120 between the locked and unlocked positions. The locking clamp can be a clamping piece-shaped component arranged along the axial direction of the locking piece, and a clamping portion 121 is arranged on the locking clamp and can be attached to the locking piece 110 when the clamping piece 120 is in the locking position.

In some embodiments, the number of latching clips may be two. In some embodiments, the two latching clips are symmetrically distributed about the axis of the operating member. In some embodiments, the inner side of each locking clip is provided with a protrusion (i.e. the clamping portion 121), and correspondingly, the locking member 110 may be provided with two grooves (i.e. the locking portions) symmetrically distributed with respect to the axis. When the two locking clips are in the locking positions, the protrusions on the two locking clips are matched with the corresponding grooves respectively. In some embodiments, the number of latching clips may be more than two, such as 3, 4, etc. A plurality of locking clips may be distributed around a circumference of the locking member 110. In some embodiments, the number of latching clips is related to the profile of the latching clips. For example, the locking clip may include two hollow semi-cylindrical shaped jaws symmetrically disposed about an area between the jaws through which the locking member 110 passes. As another example, the locking clip may include three shingled clips arranged in three equal halves with an area around the middle of the three clips for the locking member 110 to pass through.

In some embodiments, referring to fig. 1 and 4, the outer side of the locking clip may include a first inclined surface 122, and an end of the first inclined surface 122 near the first position 160 is inclined in an outward direction with respect to the axis of the locking member 110, i.e., an end of the first inclined surface 122 near the first position 160 is away from the axis of the locking member 110, and an end near the second position 170 is close to the axis of the locking member 110. In some embodiments, the first ramp 122 may be the entire outer side of the latching clip or may be a portion of the outer side. In some embodiments, the first inclined surface 122 may contact the inner side surface of the operating member during the movement of the operating member between the first position 160 and the second position 170, and through this contact relationship, the first inclined surface 122 may convert a downward force (e.g., a gravitational load applied to the operating member by the battery 200) applied to the operating member by the operating member in the axial direction of the operating member into an inward pressure force perpendicular to the axial direction on the locking clip, which may cause the locking clip to have an inward movement tendency perpendicular to the axial direction, further enhancing the engagement of the locking clip with the locking member 110, and increasing the fixing effect of the fixing device 100.

In some embodiments, the value of the first angle of inclination may be related to the load to which the operating member is subjected. The value of the first inclination angle may affect the rate at which the first ramp 122 converts the load into pressure. The larger the value of the first inclination angle, the larger the conversion rate, and the larger the pressure applied to the first inclined surface 122 for the same load. Therefore, the value of the first inclination angle is determined according to the load borne by the operating element, so that the overlarge pressure borne by the first inclined surface 122 can be avoided, and the possibility of damage to the lock clamp is reduced. In some embodiments, the first inclination angle may be greater than 0 ° and less than 90 °.

In some embodiments, the outer side of the locking clip is a tapered surface, the end of the tapered surface near the mounting hole of the battery 200 has a first outer diameter, and the end of the tapered surface far from the mounting hole has a second outer diameter; the first outer diameter is smaller than the second outer diameter. Thus, the locking clip may also be in a circular truncated cone shape, and the first inclined surface 122 in a tapered surface may contact with the operating element 130, so that the load of the operating element 130 is converted into an inward pressure perpendicular to the axis, thereby further increasing the fixing effect of the fixing device 100. In some embodiments, the outer side surface of the locking clip may also be in other shapes such as rectangle, triangle, trapezoid, etc., which are not described herein.

FIG. 5 is a schematic diagram of an operating member 130 according to some embodiments of the present disclosure. In some embodiments, the operating member 130 may be a component that controls the switching of the locked state and the unlocked state of the fixing device 100. The operation member 130 can drive the engaging member 120 to move by moving itself, so as to change the relative position between the engaging member 120 and the locking member 110, thereby realizing the switching between the locking state and the unlocking state of the fixing device 100. For example, when the control operation member 130 moves from the first position 160 to the second position 170 (e.g., the control operation member 130 moves upward), the latch 120 is moved from the locking position to the unlocking position, so that the relative positions of the latch 120 and the locking member 110 are changed from the engaging position to the disengaging position, and the fixing device 100 is switched from the locking state to the unlocking state. The relative positions of the clamping member 120 and the locking member 110 can refer to the related contents of the clamping member 120 and the locking member 110, and are not described herein again.

In some embodiments, referring to FIG. 5, the operating member 130 may be sleeve-shaped. For example, the operating member may be a cylindrical sleeve or a tapered sleeve. In some embodiments, the operating element 130 is sleeved on the clamping member 120, and the clamping member 120 can be sleeved on the locking member 110. For example, the locking member 110 may be disposed at the innermost layer, the engaging member 120 may be disposed at the middle layer, and the operating member 130 may be disposed at the outermost layer. Thus, since the operation element 130 is movably connected to the engaging member 120, the movement of the operation element 130 at the outermost layer is controlled to drive the engaging member 120 at the middle layer to move, so that the fixing and detaching of the fixing device 100 can be realized. In some embodiments, the shape of the hollow portion of the operating member may correspond to the shape of the snap-in member. In some embodiments, the hollow portion of the operating member may provide a movement space for the snap member.

In some embodiments, referring to fig. 6A, the operating member 130 (e.g., a lock sleeve) can be in the first position 160, the latch member 120 (e.g., a lock clip) can be in the locked position, and the latch portion (e.g., a protrusion) and the locking portion (e.g., a recess) can cooperate to place the fixing device 100 in the locked state. Referring to fig. 6B, the operating member 130 (e.g., the lock sleeve) is in the second position 170, the latch member 120 (e.g., the lock clip) is in the unlocked position, and the latch portion (e.g., the protrusion) and the locking portion (e.g., the recess) are separated, thereby determining that the fixing device 100 is in the unlocked position.

To install the fixing device 100, a portion of the engaging portion can be moved into the locking portion in advance, and then the operating member 130 is controlled to move from the second position 170 to the first position 160, so that the operating member 130 drives the engaging member 120 to move, and the engaging portion and the locking portion are engaged. In some embodiments, the preliminary action of the snap-in portion and the locking portion may be achieved by providing magnets that attract each other. The magnet can be used for making the joint portion and the sticking portion that the position is close have the actuation trend to drive joint portion and remove and cooperate in the sticking portion, realize fixing device 100's fixed function automatically. For example, the clamping part is a raised ferromagnetic material, and a magnet is arranged in the groove of the locking part. By providing the magnet, an initial force for urging the clamping portion and the locking portion to be matched with each other can be provided between the clamping portion and the locking portion, and when the clamping portion and the locking portion are separated from each other, the operating member 130 can overcome the magnetic force to move the clamping portion out of the locking portion. In some embodiments, when the magnet is not provided, the pre-action of the clamping part and the locking part can automatically realize the fixing function of the fixing device 100 by moving the clamping member 120 from the unlocking position to the locking position by manually moving the clamping member 120.

In some embodiments, in the process of installing the fixing device 100, in order to make the clamping portion stay at the position corresponding to the locking portion and avoid that the clamping portion and the locking portion have a height difference and cannot be matched, a limiting member may be provided to limit a movement position of the clamping member along an axial direction of the locking member. In some embodiments, the limiting member may limit the position of the engaging member 120 along the axial direction of the locking member after the operating member 130 moves from the second position to the first position, so that the engaging portion is limited from moving downwards after moving downwards along the axial direction of the locking member to the same height position as the locking portion. In some embodiments, the position-limiting member may be any one or a combination of a position-limiting rod, a circular truncated cone, a prism and a cone.

In some embodiments, one end of the limiting member may be fixed relative to the locking member 110, and when the operating member 130 moves to the first position 160, the engaging member 120 abuts against the other end of the limiting member, and the limiting member may prevent the engaging member 120 from continuing to move downward along the axial direction of the locking member 110 due to an external force, so that the engaging portion and the locking portion are located on the same horizontal plane. For example, in the case that the operating member 130 is provided with a sealing cover at one end near the first position, the limiting member may be disposed in the sealing cover, one end is fixedly disposed in a groove of the sealing cover, and the other end is disposed on the path of the axial movement of the clamping member 120. The position of the clamping portion limited by the limiting part can be adjusted by adjusting the depth of the sealing cover groove and/or the length of the limiting part, so that the height difference between the clamping portion and the locking portion is adjusted.

In some embodiments, referring to fig. 4 and 5, the side wall of the clip 120 is provided with a guide groove 123, the operating element 130 is provided with a guide post 124 at a position corresponding to the guide groove 123, and the guide post 124 is disposed in the guide groove 123 and can slide relative to the guide groove 123. When the operating member 130 moves between the first position 160 and the second position 170, the operating member 130 can move relative to the axis of the clamping member 120 under the action of the guide post 124.

The guide groove 123 may be a recessed structure capable of guiding the moving direction of the object, such as a cavity, a through groove, etc. for guiding the movement of the guide post 124. In some embodiments, the guide groove 123 may be a cavity having a guide space perpendicular to the axial direction of the operating member 130. For example, the guide groove 123 may be a straight groove obliquely arranged perpendicular to the axis of the operation member 130. For another example, the guide groove 123 may be an arc-shaped groove or a curved groove that is curved outward with respect to the axis of the operation member 130. In some embodiments, the guide groove 123 may have various cross-sectional shapes in a plane parallel to or coincident with the axis of the operating member 130. For example, according to the sectional shape, the guide groove 123 may include, but is not limited to, a rectangular groove, a key groove, a circular groove, an annular groove extending along a sidewall of the operation member 130, and the like. In some embodiments, the cross-sectional shape of the guide groove 123 may be determined according to the shape of the portion contacting the guide groove 123, for example, when the portion contacting the guide groove 123 is a cylinder, the guide groove 123 may be a key groove or an annular groove.

In some embodiments, the guide groove 123 may be provided on the first slope of the snap 120. When the operating member 130 moves along the guide groove 123, the catching member 120 may move relative to the axis of the locking member by the force applied to the contact portion with the guide groove 123.

In some embodiments, the length of the guide groove 123 may be determined according to the distance between the first position 160 and the second position 170. For example, the length of the guide slot 123 may be greater than the distance between the first position 160 and the second position 170. For another example, the length of the guide groove 123 may be 1.2 to 1.5 times the distance between the first position 160 and the second position 170.

In some embodiments, the guide groove 123 may be disposed obliquely with respect to the axis of the operating member 130. For example, the guide groove 123 may be a straight groove that is obliquely arranged with respect to the axis of the operation member 130. In some embodiments, the guide slot 123 may be angled outwardly relative to the axis of the operating member 130, i.e. the end of the guide slot 123 adjacent the second position 170 is closer to the axis of the operating member and the end of the guide slot 123 adjacent the first position 160 is further from the axis of the operating member. For example, the horizontal distance between the end of the guide groove 123 near the second position 170 and the axis of the operating member 130 is smaller than the horizontal distance between the end of the guide groove 123 near the first position 160 and the axis of the operating member 130. In some embodiments, the guide groove 123 may be provided on the same side of the clip member as the clip portion. In some embodiments, the guide groove 123 may be provided on a side surface of the clip member adjacent to the clip portion, thereby facilitating reduction of thickness of the side wall of the clip portion.

In some embodiments, the guide post 124 may be a component that guides the movement of the clip 120. In some embodiments, the guiding post 124 can move along the guiding groove 123 relative to the clip member 120, and during the movement, a force is applied to the guiding groove 123, so as to drive the clip member 120 to move.

In some embodiments, during movement of the operating member 130 from the first position 160 to the second position 170, the guide post 124 follows the direction of movement of the operating member 130. Because the guide groove 123 inclines, the guide post 124 applies the pushing force to the guide groove 123 along the inclined direction, and because of the limiting effect of the locking part, the clamping piece 120 can keep a static state in the vertical direction and can move along with the inclined guide groove 123 in the horizontal direction. In some embodiments, when the operating element 130 moves from the first position 160 to the second position 170, the guiding post 124 can generate a pushing force on the side surface of the guiding groove 123 away from the axis of the operating element in a direction away from the axis of the operating element, so that the clamping member tends to move away from the axis of the operating element, and the engagement between the clamping member and the locking member is released. In some embodiments, when the operating member 130 moves from the second position 170 to the first position 160, the guiding post 124 can push the side surface of the guiding groove 123 close to the axis of the operating member in the direction of the axis of the operating member, so that the clamping member tends to move in the direction of the axis of the operating member, and the clamping member and the locking member are engaged with each other.

In some embodiments, the guiding groove 123 may be disposed on the operating member instead of the clip member, and correspondingly, the guiding pillar 124 is disposed on the clip member. In some embodiments, the operating member 130 may be provided with a guide groove 123 on a side wall thereof. When the operating member 130 moves between the first position 160 and the second position 170, the guide post 124 can guide the movement of the card member 120 relative to the axis of the operating member 130 under the force applied by the guide slot 123.

In some embodiments, the guide groove 123 may be disposed obliquely with respect to the axis of the operating member 130. In some embodiments, the guide slot 123 may be angled outwardly relative to the axis of the operating member 130, i.e. the end of the guide slot 123 adjacent the second position 170 is closer to the axis of the operating member and the end of the guide slot 123 adjacent the first position 160 is further from the axis of the operating member.

In some embodiments, the guide groove 123 may be disposed at a side near the catching portion 121. In some embodiments, during the process of the operation member 130 moving from the first position 160 to the second position 170, the obliquely arranged guide groove 123 moves along with the moving direction of the operation member 130, so that the guide groove 123 applies an urging force to the guide post 124 in the oblique direction, and due to the limiting function of the locking portion, the snap-in member 120 keeps a stationary state in the vertical direction and moves along with the oblique guide groove 123 in the horizontal direction. In some embodiments, when the operating member 130 moves from the first position 160 to the second position 170, the side surface of the guiding groove 123 close to the axis of the operating member can generate a pushing force on the guiding post 124 of the clamping member in a direction away from the axis of the operating member, so that the clamping member tends to move in a direction away from the axis of the operating member, and the engagement between the clamping member and the locking member is released. In some embodiments, when the operating member 130 moves from the second position 170 to the first position 160, the side of the guiding groove 123 away from the axis of the operating member can generate a pushing force on the guiding pillar 124 of the engaging member toward the axis of the operating member, so that the engaging member tends to move toward the axis of the operating member, and the engaging member and the locking member are engaged.

In some embodiments, the latch and/or the operating member may not include the guide groove 123 and/or the guide post 124. In some embodiments, when the clip 120 is two locking clips symmetrically disposed with respect to each other, a separation structure may be disposed between the two locking clips in order to unlock the fixing device 100. When the operation member 130 moves from the first position 160 to the second position 170, the separation structure enables the two locking clips to move towards the direction away from each other under the action of the separation structure, so as to drive the clamping portion to leave the locking portion.

In some embodiments, the separation structure may be a cam structure disposed between the two locking clips, the cam structure may include a cam and a transmission part connected to each other, a peripheral wall of the cam is in contact with the locking clips, the transmission part is connected to the operating member 130, and the transmission part may rotate the cam along with the movement of the operating member 130. The transmission portion may be a member that transmits kinetic energy. In some embodiments, the transmission may change the direction of movement of the object. For example, the transmission part may transmit kinetic energy of the operating member 130 moving from the first position to the second position to the cam, so that the movement of the operating member 130 may rotate the cam. In some embodiments, the transmission portion may include one or more of the following: a gear transmission mechanism, a link transmission mechanism, a rack and pinion transmission mechanism, etc., which are not particularly limited in this specification.

The cam can make two lock clamps with mutually close positions have a separation trend through rotating, so that the part of the clamping part is driven to leave the locking part, and the unlocking of the fixing device 100 is realized. For example, when the operating member 130 moves from the first position 160 to the second position 170, the transmission portion can move along with the operating member 130 to drive the cam to rotate, so that the cam with a larger radius rotates between the two locking clips, and a force for urging the two locking clips away from each other is provided between the two locking clips. When the operating member 130 moves from the second position 170 to the first position 160, the transmission portion can move along with the operating member 130 to drive the cam to rotate, so that the portion with the smaller radius of the cam rotates between the two locking clips, and the two locking clips can approach each other.

In some embodiments, the separating structure may be a resilient member disposed between two latching clips. The elastic member can be used for separating two locking clips with close positions, so that the clamping portion is driven to leave the locking portion, and the fixing device 100 is unlocked. In some embodiments, the resilient member is a spring. In some embodiments, a spring is disposed between opposing sidewalls of the two latching clips, one end of the spring being connected to a sidewall of one latching clip and the other end being connected to a sidewall of the other latching clip, the spring being in a compressed state when the two latching clips are brought into proximity with each other. When the two latching clips are moved closer to each other by the pressure of the operating member, the operating member 130 can overcome the elastic force of the spring to move the two latching clips closer to each other because the elastic force of the spring is small, and when the pressure of the operating member on the two latching clips is removed, the elastic force of the spring urges the two latching clips away from each other. In some embodiments, the resilient member may be a torsion spring. The torsion spring can be connected with one end of the two locking clips close to the second position 170, and provides torque force for the two locking clips to enable the clamping parts of the two locking clips to rotate outwards, so that the clamping parts of the two locking clips are far away from each other.

Figure 7 is a schematic diagram of a latching clip and separator shown in accordance with some embodiments of the present disclosure. In some embodiments, to maintain the separation after the latching clips are separated, a separator 180 may be provided between the latching clips to prevent the latching clips from closing. In some embodiments, as shown in fig. 7, the separating member 180 may include an operating portion 181 and a separating portion 182, and the separating member 180 may keep the latching clips separated by the separating portion 182. In some embodiments, the operating portion 181 may be a component that moves the separating portion 182. In some embodiments, the separating part 182 may be a protrusion disposed on an inner wall (a side near the locking clip) of the operating part 181, and the separating part 182 of the separating member 180 may be inserted between a plurality of locking clips when the locking clips are separated, and the locking clips are separated by the separating part 182 to prevent the locking clips from being folded again.

In some embodiments, separating member 180 may further include a reset portion 183, and separating member 180 is reset by reset portion 183. In some embodiments, the reset portion 183 may be an elastic member disposed on an inner wall of the operating portion 181, and one end of the reset portion 183 is fixed to an inner wall (a side near the latching clip) of the operating portion 181 and the other end is fixed to the operating member 130 or contacts with an outer peripheral wall of the latching clip. For example, the separating member 180 may compress the reset portion 183 through the operating portion 181 when being inserted between the plurality of latching clips, and when the separating member 180 needs to be reset, the compressed reset portion 183 may provide an elastic force to make the separating portion 182 move away from between the plurality of latching clips, thereby resetting the separating member 180.

In some embodiments, maintaining the separation of the latching clips may be accomplished by controlling the movement of the operating portion 181. For example, when the locking clips are separated, the operation part 181 can be controlled to move the separating piece 180 between the locking clips to maintain the separation of the locking clips; when the latching clips are closed, the control operation on the operation portion 181 can be canceled so that the separating member 180 is moved out of the latching clips by the elastic force of the reset portion 183. In some embodiments, the separating member 180 may be disposed at the bottom of the operating member 130 and may move along with the operating member 130. For example, when the operation element 130 is in the first position, the locking clip is closed, the operation portion 181 can drive the separating element 180 to move out of the locking clip under the elastic force of the reset portion 183, and when the operation element 130 is in the second position, the locking clip is separated, the operation portion 181 can drive the separating element 180 to move between the locking clips, so as to prevent the locking clip from being closed.

In some embodiments, referring to FIG. 2, the fixing device 100 can further include a reset member 140, and the reset member 140 can be used to provide a biasing force to the operating member 130 to enable the operating member 130 to move from the second position 170 to the first position 160.

In some embodiments, the restoring member 140 may be a compressible component, such as a spring, an elastic ball, or other elastic member. In some embodiments, the reset member 140 may be disposed between the operation member 130 and the mounting portion of the battery 200. In some embodiments, the reset member 140 may also provide a space for the operating member 130 to displace from the first position 160 to the second position 170. When the operating member 130 moves from the first position 160 to the second position 170, the restoring member 140 is elastically deformed after being compressed, so as to apply a biasing force to the operating member 130 to restore the operating member 130, i.e., push the operating member 130 back to the original first position 160. In some embodiments, the return element 140 may be made of spring steel, rubber, or the like. In some embodiments, only one reset element 140 may be provided, such as a spring that may be disposed over the locking element 140. In some embodiments, a plurality of the reset members 140 may be provided, such as 2 springs disposed around the locking member 140, and the present embodiment does not limit the specific number of the reset members 140.

In some embodiments, when the electric vehicle moves, the reset member 140 may further be configured to provide a certain displacement space for the battery 200, so that the battery 200 may shake with the jolt of the electric vehicle at a small amplitude, thereby reducing stress on the battery 200 and the chassis due to flexible deformation and avoiding damage to the device.

In some embodiments, the reset 140 may comprise a spring. In some embodiments, the snap-fit portion engages the locking portion when the securing device secures the battery 200, and the spring is in a compressed state. One end of the spring may contact the operation member 130 and the other end may contact the battery 200. In some embodiments, the spring is a mechanical part with elasticity, and the spring in a compressed state can apply corresponding biasing forces to two ends of the spring. For example, the spring may apply a biasing force to the operation member 130 and the battery 200 when the snap-in portion is engaged with the locking portion. The operating member 130 can convert the biasing force into a pressing force applied to the catching member 130 so that the catching portion is more closely fitted to the locking portion. Meanwhile, the biasing force applied by the spring to the battery 200 can also make the fit between the battery 200 and the electric vehicle tighter, and even in the case of bumping and shaking of the electric vehicle, the fixing device 100 can still lock the battery 200 and fit the electric vehicle.

In some embodiments, the spring may or may not be sleeved on the locking member 110. The present embodiment is not particularly limited with respect to the relative position between the spring and the locking member and the number of springs.

In some embodiments, the fixing device 100 further includes a flange fixedly connected to one end of the restoring member 140; the other end of the reset member 140 is connected to the operation member 130. The flange may be a connection between two components, which may serve to increase the stability of the interaction between the two components being connected. For example, one end of the flange may be connected to the reset member 140, and the other end of the flange may contact the battery 200, and the flange may increase the stability of the interaction between the battery 200 and the reset member 140, so that the battery 200 may still be attached to the electric vehicle when the electric vehicle bumps or vibrates.

In some embodiments, the flange may include a locking through hole and a reset groove at the same center point, the locking through hole may allow the locking member 110 to pass through, and the reset groove may cooperate with the reset member 140 to define the positions of the locking member 110 and the reset member 140, thereby preventing the fixing effect from being weakened due to the component offset.

In some embodiments, the fixing device 100 may further include a sealing cover 150, and the sealing cover 150 is sleeved outside the operating member 130. In some embodiments, a sealing boot 150 may be used to seal the snap member 120 and the operating member 130. In some embodiments, the sealing cover 150 may be used to seal the snap member 120, the operation member 130 and the reset member 140. In some embodiments, one end of the seal cap 150 is fixed. For example, one end of the sealing cap 150 may be fixedly coupled to the flange. In some embodiments, the other end of the sealing cap 150 may be fixedly coupled to the operating member 130. For example, the other end of the sealing cover 150 may be fixedly connected to the outer peripheral wall of the operation member 130, or may be fixedly connected to the bottom of the operation member 130. In some embodiments, the other end of the sealing cap 150 may also be fluidly connected to the operating member 130. For example, the other end of the seal cover 150 may be in slidable contact only with the outer peripheral wall of the operation member 130. In some embodiments, the seal housing 150 is retractable in the direction of movement of the operating member 130. In some embodiments, when the fixation device includes a reset element, the sealing cap 150 may be sleeved outside the reset element.

The sealing cap 150 may be a corrosion-resistant protective cap that can prevent external oil and moisture from corroding the fixing assembly, thereby prolonging the service life of the fixing device 100. In some embodiments, the sealing cover 150 may be made of plastic, nylon, or other materials with good corrosion resistance, or may be made of natural rubber, silicone, or other materials with good elasticity. In some embodiments, a support plate (e.g., a PVC plate, etc.) may be provided on the inside of the sealed enclosure. The support plate can prevent the sealing cover 150 from being excessively plastically deformed by a shock, and can increase the high temperature resistance of the sealing cover 150. The material of the sealing cap 150 is not particularly limited in this embodiment.

In some embodiments, the sealing cap 150 may include a plurality of folded portions, and the state of the plurality of folded portions may be determined according to the position of the operating member 130. For example, the seal cover 150 may be a bellows cover, and a folded portion of the bellows cover may be unfolded when the operation member 130 is in the first position 160 and folded when the operation member 130 is in the second position 170. In some embodiments, the sealing cap 150 may include a telescoping portion that may enable telescoping of the sealing cap 150 by switching between an extended state and a stretched state. For example, the sealing cap 150 may be a woven mesh that may be stretched when the operating member 130 is in the first position 160 and stretched when the operating member 130 is in the second position 170.

In some embodiments, the fixture 100 may further include a sealing cap that may be disposed at an end of the operating member 100 proximate the first position 160.

The sealing cover can be an oil leakage-proof and pollution-proof protecting cover, can prevent external pollution from entering the fixing device 100 from the end face of the operating piece 100, can also prevent lubricating oil in the fixing device 100 from flowing out, and avoids that the friction force is too large due to oil leakage, so that the fixing device 100 is damaged when in use. For example, the sealing cover may be an oil seal structure. In some embodiments, the sealing cap may be the same material as the sealing cap 150, or a different material. The sealing cover can be made of plastic, nylon and other materials with good corrosion resistance, and can also be made of natural rubber, silica gel and other materials with good elasticity. The present embodiment is not particularly limited with respect to the material of the seal cap.

In some embodiments, the battery 200 may include a mounting portion through which the fixing device 100 is connected to the battery 200 when the fixing device 100 fixes the battery 200. The mounting portion of the battery 200 may be a structure or a portion for mounting on the battery 200. In some embodiments, the mounting portion of the battery 200 may be a through hole provided on the battery. In some embodiments, the locking member 110 may pass through the through-hole, with the first end 111 of the locking member 110 being located on one side of the battery and the second end 112 of the locking member 110 being located on the other side of the battery. The engaging member 120 and the operating member 130 can be sleeved on the locking member 110 from the second end 112 of the locking member 110, and the battery 200 and the locking member 110 are axially fixed by the engagement between the engaging portion of the engaging member 120 and the locking portion of the second end 112 of the locking member 110.

In some embodiments, the mounting portion of the battery 200 is disposed above the operating member. For example, the battery 200 may be placed between the chassis and the operating member. In some embodiments, the mounting portion of the battery 200 is disposed above the reset member. For example, the battery 200 may be placed between the chassis and the reset member. In some embodiments, the mounting portion of the battery 200 is disposed above the flange. For example, the battery 200 may be placed between the chassis and the flange. In some embodiments, the locking member includes a locking cap, and the region between the locking cap and the flange may be used to provide a mounting portion for the battery 200. In some embodiments, a bumper pad is disposed under the locking cap, and the area between the bumper pad and the flange may be used to provide a mounting portion for the battery 200. Thus, the locking member passes through the mounting portion of the battery 200, and the operating member and the clamping member can be mounted below the mounting portion of the battery 200, and through the cooperation of the clamping member and the locking member, the mounting portion and the locking member of the battery 200 cannot be separated in the axial direction of the locking member, so that the fixing device 100 is in a locked state to fix the battery 200.

In some embodiments, as shown in fig. 8, the fixing device 100 can include the latch 120, the operation member 130, the reset member 140, the flange and the sealing cover 150 as a latch unit during the locking process and the unlocking process, and the latch unit can be separated from the locking member 110 and remain as a unit after the separation.

In some embodiments, in order to enhance the stability and reliability of the connection between the latch 120, the operating member 130, the reset member 140, the flange, and the sealing cap 150, one or more connecting rods 190 may be provided in the latch assembly. In some embodiments, as shown in FIG. 8, a connecting rod 190 may be disposed within the clamping assembly, a first end 191 of the connecting rod 190 may be coupled to the flange, and a second end 192 of the connecting rod 190 may be coupled to the actuator 130.

In some embodiments, a cavity may be disposed within the interior of the operating member 130, and the second end 192 of the connecting rod 190 may be disposed within the cavity through the through-hole, such that the cavity is capable of moving relative to the connecting rod 190 when the operating member 130 moves between the first position 160 and the second position 170, and the connecting rod 190 does not follow the operating member 130. For example, when the operating member 130 moves to the first position 160, the second end 192 of the connecting rod 190 abuts against an end of the cavity near the through hole; when the operating member 130 moves to the second position 170, the second end 192 of the connecting rod 190 abuts against an end of the cavity away from the through hole. In some embodiments, the horizontal cross-section of the second end 192 of the connecting rod 190 may be larger than the through hole of the operating member 130, thereby limiting the operating member 130. For example, when the operating element 130 moves to the first position 160, the second end 192 of the connecting rod 190 cannot pass through the through hole, so that the operating element 130 is prevented from moving excessively, and the operating element 130 is prevented from separating from the connecting rod, thereby improving the stability of the whole clamping.

In some embodiments, the process of mounting the battery 200 on the electric vehicle by the fixing means and locking is performed as follows:

in order to install the battery 200, the locking cap and the buffer washer of the locking member 110 may be fixed to the electric vehicle, and then the battery 200 and the clamping unit are integrally and sequentially sleeved on the locking member 110. In some embodiments, the clamping portion can be pushed upward (in a first direction 310 shown in fig. 8) along the axis of the locking member to the position of the locking portion by an external force, and a part of the clamping portion enters the locking portion in advance. After a portion of the engaging portion enters the locking portion, the external force is removed, the operating element 130 moves downward (in a second direction 320 as shown in fig. 8) along the axis of the locking member under the action of the gravity of the battery 200, so that the operating element moves from the second position 170 to the first position 160, and the inclined surface on the outer surface of the engaging portion drives the engaging portion of the engaging member 120 to move toward the inside of the locking portion, so that the engaging portion and the locking portion are matched to lock the fixing device 100. In some embodiments, the gravity of the battery 200 can be transmitted from the reset member to the operation member 130, and the bias force of the reset member 140 to the operation member 130 causes the operation member to move downward (in the second direction 320 shown in fig. 8) along the axis of the locking member, so that the clamping member 120 is folded inward, and the clamping portion is engaged with the locking portion to lock the fixing device 100. By using the fixing device in the embodiment of the specification, the fixing device 100 can be locked only by pushing the clamping piece upwards, and the battery 200 can be fixed with the electric vehicle after being locked, so that the installation efficiency of the battery 200 is improved.

In some embodiments, the process of unlocking the fixing device and detaching the battery 200 from the electric vehicle is as follows:

when the fixing device 100 is in the locked state, in order to unlock the fixing device 100, a pressure may be applied to the operating element 110 upward along the axis of the locking member (as shown in the first direction 310 in fig. 8), which may be greater than the gravity of the battery 200 and the fixing device 100, so that the operating element 130 may move upward against the biasing force of the reset member, and drive the engaging portion of the engaging member 120 to move outward through the guide groove 123, so as to separate the engaging portion from the locking portion, thereby unlocking the fixing device 100, and thus detaching and separating the engaging unit from the locking member 110. Then, the battery 200 may be detached from the locking member 110, thereby achieving detachment of the fixing device 100. By using the fixing device in the embodiment of the present specification, only one action of pushing the operating element 110 upward is needed to unlock the fixing device 100, and after unlocking, the battery 200 can be detached from the electric vehicle and taken out, so that the detachment efficiency of the battery 200 is improved.

The beneficial effects that may be brought by the embodiments of the present description include, but are not limited to: (1) by arranging the inclined surface and the guide groove on the clamping piece, the fixing device can switch the locking state or the unlocking state only by controlling one-time movement of the operating piece to drive the clamping piece to move, so that a large amount of loading and unloading time can be saved, and the efficiency of replacing the assembly is improved; (2) through setting up guide slot and guide post for the axial motion of control operating parts can change the cooperation between joint spare and the locking piece, do not need meticulous operation promptly and can realize the switching of fixing device state, and the joint spare also is difficult for taking place to interfere or warp with the locking piece in loading and unloading process, frictional force between joint spare and the locking piece is also less, can reduce the moment attenuation that leads to because of frequent loading and unloading and be applicable to dismantlement and installation many times, ensure to make the more stability of fixed object on the fixing device.
