Specific implementations of the present application are described in more detail below with reference to specific embodiments:

referring to fig. 2, 3 and 4, an embodiment of the present invention provides a case body, which includes a case bottom 100, a rotating shaft assembly 200, a case cover 300, a locking assembly 400, a first torsion spring 500 and a reset structure 600.

Referring to fig. 5, the front side of the box bottom 100 is provided with an unlocking slide hole 101 extending in the front-back direction, and the upper side thereof is provided with a fastening port 102 leading to the unlocking slide hole 101, the rear end of the box bottom 100 is connected with two adapter seats 110 disposed at an interval, and one side of the adapter seat 110 facing to another adapter seat 110 is provided with a fastening hole 111; two ends of the rotating shaft assembly 200 are respectively in sleeve fit with the switching holes 111 of the two switching seats 110; the rear end of the box cover 300 is rotatably connected with the rotating shaft assembly 200, the front end of the box cover 300 can rotate around the rotating shaft assembly 200 and pass through a covering position and an opening position, the lower side of the front end of the box cover 300 is connected with a fastening structure 310, and the fastening structure 310 penetrates into the fastening port 102 when the front end of the box cover 300 is in the covering position; the locking assembly 400 comprises a locking seat 410 in sliding fit with the unlocking slide hole 101 and a locking structure 420 connected to the upper side of the locking seat 410, wherein the locking seat 410 can drive the locking structure 420 to move from a locking position to an unlocking position along the unlocking slide hole 101 under the action of external force, the locking structure 420 is in buckling fit with the buckling structure 310 when the locking structure is in the locking position and the front end of the box cover 300 is in the covering position, and the locking structure 420 is released from the buckling relation with the buckling structure 310 when the locking structure is in the unlocking position; the first torsion spring 500 is in sleeve fit with the rotating shaft assembly 200 and can drive the box cover 300 to rotate from the cover position to the open position when the buckling structure 310 and the locking structure 420 are in a buckling relation; the reset structure 600 elastically abuts between the locking assembly 400 and the cassette bottom 100, and is used for resetting the locking structure 420 from the unlocking position to the locking position.

It should be noted that the rotation shaft assembly 200 can be supported together through the rotation holes 111 of the two adapters 110, based on which, the rear end of the box cover 300 is rotatably connected to the rotation shaft assembly 200, so that the box cover 300 and the box bottom 100 can establish a relative position relationship and a relative connection relationship, based on which, the box cover 300 can rotate around the rotation shaft assembly 200, and the front end of the box cover 300 can rotate sequentially through the covering position and the opening position. When the front end of the box cover 300 is in the closed position, the box cover 300 covers the box bottom 100, and when the front end of the box cover 300 is in the open position, the box cover 300 and the box bottom 100 form an included angle, that is, the box cover 300 opens the box bottom 100.

It should be noted that, the first torsion spring 500 is sleeved on the rotation shaft assembly 200, one end of the first torsion spring 500 extends to the case bottom 100, and the other end of the first torsion spring extends to the case cover 300, and the first torsion spring 500 is designed with a certain torsion force. When the front end of the box cover 300 is not locked with the front end of the box bottom 100, based on the twisting force of the first torsion spring 500, the box cover 300 will automatically rotate around the rotating shaft assembly 200 and towards the side away from the box bottom 100 until reaching the twisting angle, at this time, the box cover 300 reaches the opening position, the operation of opening the box bottom 100 is realized, and due to the effect of the first torsion spring 500, the box cover 300 can be stabilized at the opening position, so that the opening convenience of the box cover 300 can be improved, the operation is time-saving, trouble-saving and labor-saving, and the state stability of the box cover 300 at the opening position is also higher.

Meanwhile, based on the twisting force of the first torsion spring 500, the box cover 300 is difficult to cover and is easy to open by mistake after being covered to a certain degree. To solve this problem, in the embodiment, a fastening structure 310 is disposed at the front end of the box cover 300, and when the front end of the box cover 300 is rotated to the vicinity of the covering position, the fastening structure 310 can enter and exit the fastening interface 102 without collision.

And the locking seat 410 is accommodated in the unlocking slide hole 101, and can slide reciprocally along the extending direction of the unlocking slide hole 101, when no external force acts on the locking seat 410, the reset structure 600 can be elastically pressed between the locking assembly 400 and the box bottom 100, so that the locking seat 410 is stabilized at the locking position, and at this time, if the front end of the box cover 300 reaches the covering position, the fastening structure 310 can penetrate into the fastening opening 102 and be stably fastened and matched with the locking structure 420, and based on this, the fastening structure 310 can be prevented from being detached from the fastening opening 102 by the locking structure 420, so that the front end of the box cover 300 can be relatively firmly connected with the box bottom 100 at the covering position, so that the box cover 300 can be stably maintained in the state of covering the box bottom 100, the rotation tendency of the box cover 300 from the covering position to the opening position due to the first torsion spring 500 can be effectively offset, and the risk that the box cover 300 is opened by mistake can be effectively reduced.

When external force acts on the locking seat 410, the locking seat 410 can slide from the locking position to the unlocking position under the action of the external force, at this time, since the position of the fastening structure 310 is unchanged and the position of the locking structure 420 is changed, the locking structure 420 naturally releases the fastening relationship with the fastening structure 310, so that the fastening structure 310 can be disengaged from the fastening opening 102, the front end of the box cover 300 and the box bottom 100 are released from the connection relationship, subsequently, based on the torsional force of the first torsion spring 500, the front end of the box cover 300 drives the fastening structure 310 to automatically disengage from the fastening opening 102, and the front end of the box cover 300 can automatically rotate from the covering position to the opening position, thereby realizing the opening operation of the box cover 300, and ensuring the operation convenience degree of switching the box cover 300 between the covering state and the opening state. Meanwhile, in the process, the reset structure 600 is compressed and deformed due to stress, and force storage is realized.

Subsequently, when the acting force acting on the locking seat 410 is released, the reset structure 600 can recover its elastic deformation, and based on this, the locking seat 410 can be reset from the unlocking position to the locking position under the elastic force of the reset structure 600, so as to facilitate the subsequent covering and locking operation of the box cover 300 again.

To sum up, in the case body provided in the embodiment of the present application, the rear end of the case cover 300 is rotatably connected to the rotating shaft assembly 200, and the first torsion spring 500 is sleeved on the rotating shaft assembly 200, when the front end of the case cover 300 is not locked, the case cover 300 can automatically rotate from the closed position to the open position under the action of the first torsion spring 500 and can be stabilized at the open position, so that the operation convenience of switching the case cover 300 from the closed state to the open state is high, and the stability of the case cover 300 in the open state is high; when a user rotates the front end of the box cover 300 from the open position to the closed position, the fastening structure 310 connected to the box cover 300 can extend into the unlocking slide hole 101 from the fastening opening 102 and is in fastening fit with the locking structure 420 in the unlocking slide hole 101, and therefore, the fastening fit relationship between the fastening structure 310 and the locking structure 420 can ensure and improve the connection firmness between the front end of the box cover 300 and the box bottom 100 at the closed position, so that the rotation tendency of the box cover 300 from the closed position to the open position due to the first torsion spring 500 can be offset, the box cover 300 can be stably maintained at the state of covering the box bottom 100, and the risk that the box cover 300 is opened by mistake can be effectively reduced; when a user wants to open the box cover 300, the user can apply a force to the locking seat 410, so that the locking seat 410 drives the locking structure 420 to move from the locking position to the unlocking position along the extending direction of the unlocking slide hole 101, and the locking structure 420 can be easily released from the buckling and matching relationship with the buckling and matching structure 310, and at the moment, the box cover 300 can automatically rotate from the buckling position to the opening position around the rotating shaft assembly 200 under the action of the first torsion spring 500, so that the operation is very convenient; when the user releases the force applied to the locking seat 410, the locking seat 410 and the locking structure 420 are reset from the unlocking position to the locking structure 420 by the reset structure 600, so that the next lid 300 can be unfolded, closed and locked conveniently.

Therefore, the box body provided by the embodiment of the application can be switched from the closed state to the open state by the first torsion spring 500, so that the box body has high usability, and the connection firmness between the front end of the box cover 300 and the box bottom 100 at the closed position can be ensured and improved, so that the box cover 300 can be stably maintained in the state of closing the box bottom 100, and the risk that the box cover 300 is opened by mistake can be effectively reduced.

Based on the twisting force of the first torsion spring 500, the speed of the lid 300 rotating around the rotation shaft assembly 200 may be too fast, and the rotation shaft assembly 200 (or the case) is easily subjected to instantaneous impact and vibration, so that great damage may be caused to the rotation shaft assembly 200 (or the case), and the use performance and the service life of the case may be affected. To solve the above problem, please refer to fig. 6, fig. 10, and fig. 11, and please refer to fig. 3 together, in this embodiment, the rear end of the box cover 300 is connected to a first rotating arm 320 rotatably connected to the rotating shaft assembly 200, the first rotating arm 320 is provided with a first damping hole 321 penetrating through and engaged with the rotating shaft assembly 200, the box body further includes a first damping block 700, the first damping block 700 is fixedly connected to the rotating shaft assembly 200 and accommodated in the first damping hole 321, and the first damping block 700 can drive the rotating shaft assembly 200 to rotate under the driving of the first rotating arm 320; the first torsion spring 500 is compressed between the first damping block 700 and the adapter 110, and elastically abuts against the first damping block 700.

Here, the cross-sectional shape of the first damping hole 321 is the same as the cross-sectional shape of the first damping block 700, and the cross-sectional size of the first damping hole 321 is the same as the cross-sectional size of the first damping block 700. When the first rotating arm 320 rotates, the first damping block 700 retained in the first damping hole 321 can rotate synchronously under the driving of the first rotating arm 320, and accordingly, the rotating shaft assembly 200 fixedly connected with the first damping block 700 will also rotate around the central axis of the rotating shaft assembly 200 under the driving of the first damping block 700, and accordingly, the rotating shaft assembly 200 and the hole wall of at least one rotating hole 111 generate an interference friction phenomenon. The frictional force will primarily slow down the rotational speed of the cartridge cover 300 under the torsion force of the first torsion spring 500.

Optionally, the cross-sectional shape of the first damping block 700 has at least one corner, and thus the movement synchronism of the first damping block 700 and the first rotating arm 320 can be further ensured and improved, so that the first damping block 700 can effectively drive the rotating shaft assembly 200 to rotate around the central axis of the rotating shaft assembly 200.

It should be further noted that the first torsion spring 500 is disposed between the first damping block 700 and the adapter 110 relatively far from the first damping block 700, and there is a certain compressive deformation of the first torsion spring 500 in the axial direction, and based on the compressive deformation, there is always a movement tendency of the first torsion spring 500 to restore the elastic deformation, that is, there is a movement tendency to extend in the axial direction, and based on the movement tendency, the first torsion spring 500 can generate an elastic resisting force on the first damping block 700 toward the side of the adapter 110 relatively close to the first damping block 700. Although the first damping block 700 and the rotation shaft assembly 200 are limited by their positions and do not move axially due to the elastic abutting force, the elastic abutting force still can urge the rotation shaft assembly 200 to at least closely contact with the one of the rotation holes 111, so as to effectively enhance the friction force between the rotation shaft assembly 200 and the hole wall of the at least one of the rotation holes 111, thereby providing sufficient damping feeling for the rotation of the box cover 300, thereby effectively slowing down the rotation speed of the box cover 300 under the torsion of the first torsion spring 500, and preventing the box body (especially the rotation shaft assembly 200) from being subjected to instantaneous impact and vibration due to the rapid rotation of the box cover 300, thereby effectively reducing the damage degree of the box body.

Referring to fig. 6, 10, and 11, and referring to fig. 3, in this embodiment, the rear end of the box cover 300 is further connected to a second rotating arm 330 rotatably connected to the rotating shaft assembly 200 and spaced from the first rotating arm 320, the second rotating arm 330 is provided with a second damping hole 331 penetrating through and engaged with the rotating shaft assembly 200, the box body further includes a second damping block 800, the second damping block 800 is fixedly connected to the rotating shaft assembly 200 and accommodated in the second damping hole 331, and the second damping block 800 can drive the rotating shaft assembly 200 to rotate under the driving of the second rotating arm 330; the first torsion spring 500 is compressed between the first rotating arm 320 and the second rotating arm 330, and elastically abuts against the first damping block 700 and the second damping block 800.

It should be noted that in the present embodiment, the first rotating arm 320 and the second rotating arm 330 which are arranged at an interval are jointly connected with the rotating shaft assembly 200 to jointly support the box cover 300 and jointly drive the box cover 300 to rotate around the rotating shaft assembly 200, and based on the arrangement, the movement stability of the box cover 300 in the rotating process can be effectively ensured and improved, and the overall strength of the box cover 300 can be effectively enhanced.

It should be noted that the cross-sectional shape of the second damping hole 331 is the same as the cross-sectional shape of the second damping block 800, and the cross-sectional size of the second damping hole 331 is the same as the cross-sectional size of the second damping block 800. When the second rotating arm 330 rotates, the second damping block 800 limited and accommodated in the second damping hole 331 can rotate synchronously under the driving of the second rotating arm 330. Based on this, the rotating shaft assembly 200 fixedly connected with the first damping block 700 and the second damping block 800 rotates around the central axis of the rotating shaft assembly 200 under the driving of the first damping block 700 and the second damping block 800, so that not only the interference friction phenomenon is generated between the rotating shaft assembly 200 and the hole walls of the two transfer holes 111, but also the friction force between the rotating shaft assembly 200 and the hole walls of the two transfer holes 111 is relatively equalized. Therefore, the rotating speed of the box cover 300 under the torsion of the first torsion spring 500 can be further slowed down, and the moving stability of the box cover 300 in the rotating process can be further improved.

Optionally, there is at least one edge angle in the cross-sectional shape of second damping piece 800, so set up, can further ensure and improve the motion synchronism of second damping piece 800 and second rotor arm 330 for second damping piece 800 can effectively drive pivot subassembly 200 and realize rotating around the axis of pivot subassembly 200 in step.

It should be further noted that the first torsion spring 500 is disposed between the first damping block 700 and the second damping block 800, and the first torsion spring 500 has a certain compression deformation in the axial direction, and based on the compression deformation, the first torsion spring 500 always has a movement trend of restoring the elastic deformation, that is, a movement trend of extending in the axial direction, and based on the movement trend, the first torsion spring 500 can generate elastic abutting forces which are opposite to each other and both face to one side of the adaptor base 110 for the first damping block 700 and the second damping block 800, and both the elastic abutting forces are substantially balanced. Although the first damping block 700, the second damping block 800 and the rotation shaft assembly 200 are limited by their positional relationship and do not move axially due to the elastic abutting force, the elastic abutting force still causes the rotation shaft assembly 200 to be in close contact with the two rotation holes 111, so that the friction between the rotation shaft assembly 200 and the hole walls of the two rotation holes 111 can be further enhanced, and based on this, a more sufficient damping feeling can be brought to the rotation of the box cover 300, thereby further slowing down the rotation speed of the box cover 300 under the torsion of the first torsion spring 500, further avoiding the box body from being subjected to instantaneous impact and vibration due to rapid rotation, further reducing the damage degree of the box body, and further improving the motion stability of the box cover 300 in the rotation process.

Referring to fig. 6, 10, 11 and 3, in this embodiment, the rear end of the box cover 300 is further connected between the first rotating arm 320 and the second rotating arm 330 with the first supporting arm 340 and the second supporting arm 350 disposed at an interval, the first supporting arm 340 is provided with a first supporting hole at a side facing the first rotating arm 320, the second supporting arm 350 is provided with a second supporting hole at a side facing the second rotating arm 330, the rotating shaft assembly 200 includes a first rotating shaft 210 sequentially coupled with the rotating hole 111, the first damping hole 321 and the first supporting hole, and a second rotating shaft 220 sequentially coupled with the other rotating hole 111, the second damping hole 331 and the second supporting hole, the first torsion spring 500 is compressed between the first rotating arm 320 and the first supporting arm 340 and elastically supports the first damping block 700, the box body further includes a second torsion spring 900, the second torsion spring 900 is coupled with the rotating shaft assembly 200, and when the buckling structure 310 and the locking structure 420 are in a buckling relationship, the lid 300 is driven to rotate from the closed position to the open position together with the first torsion spring 500, and the second torsion spring 900 is compressed between the second rotating arm 330 and the second supporting arm 350 and elastically abuts against the second damping block 800.

It should be noted that, in the present embodiment, the first rotating shaft 210 is supported by one adapter 110 and the first supporting arm 340, and the second rotating shaft 220 is supported by the other adapter 110 and the second supporting arm 350; and then is rotatably connected with the first rotating shaft 210 through the first rotating arm 320 and is rotatably connected with the second rotating shaft 220 through the second rotating arm 330, so as to realize the rotatable connection between the box cover 300 and the box bottom 100. Based on the above structural arrangement, on one hand, the rotating shaft assembly 200 is split into two relatively short first rotating shafts 210 and second rotating shafts 220, so that the strength of the first rotating shafts 210 and the second rotating shafts 220 can be effectively strengthened to a certain extent, the fatigue strength of the first rotating shafts 210 and the second rotating shafts 220 is prevented from being influenced by the overlong length, the service lives of the first rotating shafts 210 and the second rotating shafts 220 can be correspondingly prolonged, and the movement stability of the box cover 300 in the rotating process can be further ensured and improved; on the other hand, the connection relationship between the first rotating arm 320 and the second rotating arm 330, which are arranged at an interval, and the first rotating shaft 210 and the second rotating shaft 220 is respectively established to jointly support the box cover 300, and the box cover 300 is driven to rotate around the first rotating shaft 210 and the second rotating shaft 220 jointly by the first torsion spring 500 and the second torsion spring 900, so that the acting forces on both sides can be relatively balanced, the movement stability of the box cover 300 in the rotating process can be effectively guaranteed and improved, and the overall strength of the box cover 300 can be effectively enhanced.

It should be further noted that in the present embodiment, when the first rotating arm 320 rotates, the first damping block 700 that is limited and accommodated in the first damping hole 321 can rotate synchronously under the driving of the first rotating arm 320, and accordingly, the first rotating shaft 210 that is fixedly connected to the first damping block 700 will also rotate around the central axis of the first rotating shaft 210 under the driving of the first damping block 700, and accordingly, the first rotating shaft 210 and the hole wall of the corresponding adapting hole 111 will generate an interference friction phenomenon. The frictional force primarily slows the rotational speed of the cap 300 by the torsion force of the first torsion spring 500 to slow the rotational speed of the entire cap 300.

Similarly, when the second rotating arm 330 rotates, the second damping block 800 constrained in the second damping hole 331 can rotate synchronously under the driving of the second rotating arm 330. Based on this, the second rotating shaft 220 fixedly connected to the second damping block 800 rotates around the central axis of the second rotating shaft 220 under the driving of the second damping block 800, so that not only the interference friction phenomenon between the second rotating shaft 220 and the hole wall of the corresponding adapting hole 111 can be generated, but also the friction between the first rotating shaft 210 and the hole wall of the corresponding adapting hole 111 and the friction between the second rotating shaft 220 and the hole wall of the corresponding adapting hole 111 can be relatively equalized. Therefore, the rotating speed of the box cover 300 under the torsion forces of the first torsion spring 500 and the second torsion spring 900 can be further slowed down, and the moving smoothness of the box cover 300 in the rotating process can be further improved.

Based on this, the first rotating shaft 210, the first damping block 700 and the first torsion spring 500 are used in a matching manner, and the second rotating shaft 220, the second damping block 800 and the second torsion spring 900 are used in a matching manner, so that mutual interference of movement of the two rotating shafts can be effectively avoided, the design difficulty and coordination difficulty of the box body can be effectively reduced, and the movement stability of the box cover 300 in the rotating process can be favorably ensured and improved.

It should be further noted that the first torsion spring 500 is disposed between the first damping block 700 and the first support arm 340, and a certain compression deformation exists in the axial direction of the first torsion spring 500, and based on the compression deformation, the first torsion spring 500 always has a movement tendency of restoring the elastic deformation, that is, a movement tendency of extending in the axial direction, and based on the movement tendency, the first torsion spring 500 can generate an elastic supporting force on the first damping block 700 toward the adapter 110 side. Although the first damping block 700 and the first rotation shaft 210 are limited by their positions and do not move axially due to the elastic supporting force, the elastic supporting force still can urge the first rotation shaft 210 to be in close contact with the through hole 111, so as to effectively enhance the friction between the first rotation shaft 210 and the hole wall of the through hole 111, and accordingly, a certain damping effect can be provided for the rotation of the box cover 300, thereby further reducing the speed of the box cover 300 rotating under the torsion of the first torsion spring 500, and reducing the overall rotation speed of the box cover 300, thereby effectively preventing the box body from being subjected to instantaneous impact and vibration due to rapid rotation, and effectively reducing the damage degree of the box body.

It should be further noted that the second torsion spring 900 is disposed between the second damping block 800 and the second support arm 350, and the second torsion spring 900 has a certain compression deformation in the axial direction, based on the compression deformation, the second torsion spring 900 always has a movement trend of restoring the elastic deformation, that is, a movement trend of extending along the axial direction, and based on the movement trend, the second torsion spring 900 can generate an elastic abutting force toward one side of the adaptor base 110 for the second damping block 800. Although the second damping block 800 and the second rotating shaft 220 are limited by their positions and do not move axially due to the elastic supporting force, the elastic supporting force still can urge the second rotating shaft 220 to contact the through hole 111 tightly, so as to effectively enhance the friction between the second rotating shaft 220 and the hole wall of the through hole 111, thereby providing a stronger damping feeling for the rotation of the box cover 300, further reducing the speed of the box cover 300 rotating under the torque of the second torsion spring 900, and reducing the overall rotating speed of the box cover 300, further avoiding the box body from being subjected to instantaneous impact and vibration due to rapid rotation, and further reducing the damage degree of the box body.

Based on the structure of the present embodiment, on one hand, the first rotating shaft 210 can be further split into the first rotating section 211 and the second rotating section 212 which are shorter, so that the strength of the first rotating shaft 210 can be further strengthened, the fatigue strength of the first rotating section 211 and the second rotating section 212 is prevented from being affected due to the overlong length, and the service lives of the first rotating section 211 and the second rotating section 212 can be correspondingly prolonged; on one hand, the stress transmission between the first rotating section 211 and the second rotating section 212 can be cut off, and the condition that the movement of the first rotating section 211 and the movement of the second rotating section 212 are mutually interfered can be avoided, so that the service performance of the rotating shaft assembly 200 can be further improved; in one aspect, friction between the first and second rotation sections 211 and 212 and the first torsion spring 500 may be reduced, and friction between the second rotation section 212 and a hole wall of the first support hole may be reduced, so that an unnecessary wear degree of the first rotation shaft 210 may be reduced accordingly, and thus the service lives of the first and second rotation sections 211 and 212 may be further extended.

It should be further noted that the second torsion spring 900 is located between the second damping block 800 and the second supporting arm 350, and is sleeved between the third rotating section 221 and the fourth rotating section 222, under the action of the torsion of the second torsion spring 900, the second supporting arm 350 and the fourth rotating section 222, the second damping block 800 and the third rotating section 221 will synchronously rotate around the central axis of the second rotating shaft 220, and the third rotating section 221 will generate interference friction with the hole wall of the through hole 111 under the action of the second torsion spring 900, so as to slow down the rotating speed of the box cover 300. Based on the structure of the present embodiment, on one hand, the second rotating shaft 220 can be further split into the third rotating section 221 and the fourth rotating section 222 which are shorter, so that the strength of the second rotating shaft 220 can be further strengthened, the fatigue strength of the third rotating section 221 and the fourth rotating section 222 is prevented from being affected due to the overlong length, and the service lives of the third rotating section 221 and the fourth rotating section 222 can be correspondingly prolonged; on one hand, the stress transmission between the third rotating section 221 and the fourth rotating section 222 can be cut off, and the condition that the motions of the third rotating section 221 and the fourth rotating section 222 are mutually interfered can be avoided, so that the service performance of the rotating shaft assembly 200 can be further improved; on one hand, the friction between the third rotating section 221 and the fourth rotating section 222 and the second torsion spring 900 can be reduced, and the friction between the fourth rotating section 222 and the hole wall of the second supporting hole can be reduced, so that the unnecessary wear degree of the second rotating shaft 220 can be correspondingly reduced, and the service lives of the third rotating section 221 and the fourth rotating section 222 can be further prolonged.

Based on the above structure, when the locking structure 420 is in the locking position, the limiting portion 442 can stop the hole at the side of the limiting hole 104 away from the unlocking key 430, and on the one hand, the unlocking key 430 can be limited from disengaging from the key sliding hole 103, so as to ensure and improve the connection stability of the locking assembly 400 and the box bottom 100; on the other hand, can cooperate the stable state stability of locking structure 420 in latched position of reduction structure 600 to can further ensure the fastness of being connected between locking structure 420 and the buckling structure 310, do benefit to and further improve the state stability of lid 300 in the position of closing, do benefit to and further reduce the risk that lid 300 was opened by the mistake.

Referring to fig. 2 and 4, in the embodiment, the box body further includes a detection switch 1000 disposed at the rear end of the box bottom 100 and used for detecting whether the front end of the box cover 300 is in the covering position, the rear end of the box cover 300 is connected with a detection trigger 360, and the detection trigger 360 is used for touching the detection switch 1000 when the front end of the box cover 300 is in the covering position.

It should be noted that, the detection switch 1000 is connected to the box bottom 100, the detection trigger 360 is fixedly connected to the box cover 300, and the detection trigger 360 can move synchronously with the rotation of the box cover 300, and is located at the covering position at the front end of the box cover 300, that is, when the box cover 300 covers the box bottom 100, the detection trigger 360 will touch the detection switch 1000, so as to facilitate the detection of the detection switch 1000 and determine that the front end of the current box cover 300 is located at the covering position, that is, determine that the current box cover 300 covers the box bottom 100. Therefore, in the embodiment, the detection trigger 360 is linked with the box cover 300, and a mechanical trigger mode is adopted, so that the detection of whether the box cover 300 covers the box bottom 100 is realized, the detection accuracy is high, and the use performance of the box body can be further improved.

Referring to fig. 1, an embodiment of the present application further provides an earphone charging box for receiving an earphone and charging the earphone, where the earphone charging box includes the above box body.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
