Battery B is a substantially rectangular parallelepiped elongated in the vertical direction, and is housed in battery case 33 while being slightly inclined rearward with respect to the vertical direction. This can reduce the center of gravity position while suppressing the height dimension of the battery case 33, and facilitate the attachment/detachment operation of the battery B. Further, the battery B is inclined so that the direction of drawing out (arrow shown) when the battery B is taken out from the battery case 33 is also inclined slightly rearward, but the inclination angle is within a range in which the battery B does not interfere with the large cargo C even in a state where the large cargo C is placed on the rear carrier 40.

Fig. 4 is an enlarged perspective view showing the peripheral structure of the battery case 33. Fig. 4 shows a state where the seat 29 and the seat lower cover 30 are removed and the left half of the floor upper cover 28 is removed. Fig. 5 is a configuration explanatory diagram of the battery case 33 removed from the state of fig. 4.

An operation lever 36 that is gripped by a hand and moved up and down by a worker is disposed between the two batteries B accommodated in the battery case 33. In a state where the operating lever 36 is pushed downward to connect the battery-side terminals and the case-side terminals, the push holder 42, which is pivotally supported by the swing shaft 42a so as to be swingable, comes into contact with the upper surface of the battery B with a biasing force, whereby the vertical movement of the battery B can be suppressed even when a large step is crossed during traveling.

A lock member 43 for holding the operation lever 36 in a state of being pushed downward is disposed in front of the operation lever 36. The lock member 43 is pivotally supported by the upper case 34 via a swing shaft 43a, and is switched to the unlocked state by tilting forward from the illustrated standing state.

A standing wall portion 34a constituting an upper edge of the battery case 33 is formed to be low in front and high in rear so as to follow a shape of a bottom surface of the seat 29. Thus, when the seat 29 is opened, the lock member 43 and the operating lever 36 located at the forward position are easily reached, and the operation of pulling out and inserting the battery B is also easily performed.

The battery case 33 is supported so as to be sandwiched between the left and right upright frames F4. A pair of right and left footrest retainers F11 connected in series are provided on the upright frame F4, and a cross tube F5 is disposed at a position forward below and below the upright frame F4, and the cross tube F5 forms a substantially U-shaped curve protruding upward and connects the right and left upright frames F4.

Referring to fig. 5, link mechanisms L for converting the vertical movement of the operating lever 36 into the vertical movement of the case-side terminals are arranged in a pair in the front and rear of the lower case 35 of the battery case 33. A key cylinder 45 for operating a seat lock mechanism 48 disposed at an upper portion of a rear end of the battery case 33 is disposed at a position covered by the seat lower cover 30 below the hinge 44. The seat latch mechanism 48 is covered at the upper side by the rear cover 41, and a cable 60 extending from the key cylinder 45 is connected to the left side in the vehicle width direction of the seat latch mechanism 48. A contactor 46 for turning on or off the supply of electric power to the electric components is disposed below the key cylinder 45. The cross pipe F5 connects the left and right upright frames F4 to increase the frame rigidity, and has a function of protecting electric components such as the link mechanism L and the contactor 46 disposed adjacent to the front surface of the battery case 33 in addition to a function of protecting the side surface side of the battery case 33. Further, by disposing the contactor 46 at a position close to the battery B, the harness connecting the battery B and the contactor 46 can be shortened.

Plate-shaped support stays F10 that support the front side of the battery case 33 below the link mechanism L are provided in a left-right pair on the lower surface of the horizontal tube F5 made of a steel tube. The electric components located below and behind the cross pipe F5 are also protected on the side by the support stay F10.

The front end portion of the cover member 21 is disposed behind the tandem footboard holder F11. The cover member 21 is provided with: wide portion 21a covering the side of battery case 33 to the rear of PCU 32; and a narrow portion 21b, the narrow portion 21b being connected to a lower portion of the wide portion 21a and being formed to have a width smaller than that of the wide portion 21 a.

Fig. 6 is a partially enlarged plan view of the electric motorcycle 1 with the exterior member removed. The two batteries B are arranged side by side, and an operating lever 36 having a grip portion extending in the front-rear direction is arranged at the center in the vehicle width direction between the left and right batteries B. The pressing holders 42 that press the upper surfaces of the batteries B are provided in a pair in the front-rear direction with respect to one battery B. The pressing holder 42 has: a metal body 42b pivotally supported by the swing shaft 42a so as to be swingable; and a rubber portion 42c covering the tip end side of the main body portion 42 b. The elastic force of the rubber portion 42c can stably maintain the storage state of the battery B.

The pressing holder 42, which is pivotally supported by the pivot shaft 42a so as to be pivotable, is configured to be biased by a biasing member to press the upper surface of the battery B with the biasing force in a state where the operation lever 36 is pressed, and to be pushed up by the operation lever 36 to be raised in the vertical direction by lifting up the operation lever 36.

In the present embodiment, since the pressing holders 42 are provided in a pair in the front-rear direction with respect to the battery B, when the battery B is lifted upward and brought into contact with the vertical wall portion 34a of the battery case 33 and pulled out in the vehicle width direction, the pressing holders 42 do not interfere with each other, and the battery B can be smoothly removed. This makes it possible to reduce the height required for loading and unloading the battery B as a heavy object, and to load and unload the battery B while inclining the battery B outward in the vehicle width direction, thereby facilitating the loading and unloading operation.

Battery side terminals 49 provided at the bottom of the battery B are disposed at positions on the outside of the battery B in the vehicle width direction. Accordingly, the operating lever 36 for moving the case-side terminal 55 located below the battery-side terminal 49 up and down can be operated in the same manner from either the left or right side of the vehicle body, and the replacement operation of the battery B is facilitated. Further, by disposing the operating lever 36 and the case-side terminals 55 separately, a space for providing the link mechanism L that links the operating lever 36 and the case-side terminals can be secured.

The rising frame F4 connected to the bottom frame F3 supporting the lower plate 17 from below is formed in a shape in which the distance between the left and right sides increases in the rising portion rising from the bottom frame F3 in accordance with the shape of the battery case 33. The pivot shaft 19b of the side bracket 19 supported by the upright frame F4 on the left side in the vehicle width direction is provided in a portion of the upright frame F4 that bulges outward in the vehicle width direction. Accordingly, the side bracket 19 is pivotally supported at a position on the vehicle frame F on the outside in the vehicle width direction, and when the vehicle is parked using the side bracket 19, the ground contact surface is positioned on the outside in the vehicle width direction, so that the stability of the vehicle body is improved, and the operation of unfolding and storing the side bracket 19 is facilitated. A pair of return springs 19a for biasing the side frames 19 to the expanded state and the stored state is provided outside and inside the side frames 19.

Fig. 7 is a perspective view of battery case 33 with battery B removed. The battery case 33, which is a combination of the upper case 34 and the lower case 35, is formed with a housing portion 50 into which two batteries B arranged close to each other in the vehicle width direction are inserted. Battery case 33 is formed in a bottomed box shape with its upper side open, and has improved rigidity. This presses battery B against standing wall portion 34a of upper case 34 every time battery B is attached and detached, thereby improving the durability of battery case 33.

A partition 54 for preventing contact between the left and right batteries B is provided at the bottom of the housing 50. The partition portion 54 extends upward along the front and rear inner walls of the housing portion 50 to a height of about half of the lower case 35. The partition 54 prevents the two batteries B housed in the battery case 33 from coming into contact with each other on the bottom side, and stably holds the batteries B. The partition portion 54 also functions as a guide when the battery B is inserted into the battery case 33, and the insertion operation of the battery B is also facilitated.

A base 44a to which the hinge 44 is attached is provided at the front end of the upper casing 34. A deep groove portion 51 capable of accommodating documents and the like is provided between the base 44a and the lock member 43. The deep groove portion 51 is provided by utilizing a space generated by inclining the battery B rearward with respect to the vertical direction.

As described above, the operating lever 36 is disposed between the left and right batteries B and is vertically moved by being held by the hand of the operator. When the operation lever 36 is lifted upward, the battery B is in a state of being detachable from the battery case 33, and when the operation lever 36 is pushed down, the battery-side contact 49 and the case-side contact 55 are electrically connected, and the battery B is held at a predetermined position.

The pressing holders 42 that press the upper surface of the battery B are provided in a pair in the front-rear direction with respect to the left and right storage portions 50. The battery B is a substantially rectangular parallelepiped elongated in the vehicle body vertical direction, and a surface directed outward in the vehicle width direction among the 6 surfaces constituting the battery B has a curved shape protruding outward in the vehicle width direction in a plan view of the vehicle body. This maximizes the battery capacity, and facilitates the insertion operation by easily grasping the insertion direction of battery B. Further, when the battery B is attached and detached, the surface abutting against the upper end portion of the vertical wall portion 34a of the battery case 33 is curved, so that the frictional resistance when the weight of the battery B is left at the upper end portion of the vertical wall portion 34a of the battery case 33 is small, and smooth attachment and detachment work can be performed.

When the battery B is housed in the battery case 33, the surface of the battery B on the outside in the vehicle width direction is disposed close to the upright wall portion 34a of the battery case 33 in a plan view of the vehicle body. Thus, when battery B is lifted upward and pulled out outward in the vehicle width direction, and when battery B is housed in battery case 33, the vehicle width direction outer side surface of battery B is easily brought into contact with vertical wall portion 34a of battery case 33. This makes it possible to perform the attaching and detaching operation while leaving the weight of battery B on standing wall portion 34a without completely lifting battery B, and thus the work load is reduced. As shown in fig. 4, since the standing wall portion 34a is formed so as to be low in front and high in rear when viewed from the vehicle body side, when the battery B is lifted upward and pulled out outward in the vehicle width direction and when the battery B is housed in the battery case 33, the battery B is easily tilted obliquely forward outward in the vehicle width direction, and the work of attaching and detaching the battery B is facilitated.

Fig. 8 is a perspective view of the operating lever 36. The operating lever 36 made of synthetic resin or the like has a shape to be directed forward and backward and right and left. The grip 36a for moving the operating lever 36 up and down and the connecting rod 36e extending downward for operating the link mechanism L are connected by a hollow connecting block 36 b. The lock member 43 engages with the upper surface of the front coupling block 36b, thereby restricting upward movement of the operating lever 36.

A square engaging plate 36d is provided at a substantially center in the vertical direction of the connecting rod 36e, and is adapted to abut against the lower surface of the pressing holder 42 when the operating rod 36 is lifted up, and to stand in the vertical direction. Further, a metal stay 36f that supports a pin (first shaft) 36g connected to the link mechanism L is fixed to a lower end portion of the connecting rod 36e by insert molding.

Between the grip 36a and the connecting rod 36e, a pair of front and rear spacers 36c are provided on the inner side of the connecting block 36B, and the spacers 36c are inserted between the left and right batteries B when the operating rod 36 is pressed. This makes it possible to make the operation lever 36 function as a partition plate for preventing contact between the two batteries B disposed close to each other and stably holding the two batteries B at a predetermined position.

Fig. 9 is a sectional perspective view showing a state where the battery case 33 is cut in the front-rear direction. Fig. 10 is a perspective view showing the structure of the link mechanism L. As described above, the standing wall portion 34a of the upper case 34 forming the upper opening of the battery case 33 is formed in a shape low in front and high in rear when viewed from the vehicle body side. Thus, the operation lever and the push retainer 42 are protected by the standing wall portion 34a on the rear side, and the operation lever 36 and the lock member 43 are easily accessible from the vehicle width direction on the front side.

The connecting rod 36e of the operating rod 36 is guided to the outside of the lower case 35 through an opening provided in the lower case 35, and is connected to a pair of front and rear link mechanisms L arranged in the front and rear of the lower case 35. The partition portion 54 connected to the bottom of the housing portion 50 extends to the lower portion of the engagement plate 36d when the operation lever 36 is pushed down to a predetermined position.

A left terminal cover 52 and a right terminal cover 53 that house case-side terminals 55 that move up and down in accordance with the operation of the link mechanism L are attached to the lower portion of the lower case 35. In addition, a pair of left and right support pipes 56 that support the battery case 33 from below are disposed below the lower case 35 between the left terminal cover 52 and the right terminal cover 53.

The left and right case side terminals 55 are disposed at positions corresponding to the battery side terminals 49 disposed on the outer side in the vehicle width direction, and the case side terminals 55 are connected to the battery side terminals 49 by protruding upward from the bottom of the lower case 35 by pushing down the operating lever 36, while moving to a position lower than the bottom of the lower case 35 by lifting up the operating lever 36. In this way, the case-side terminals 55 are disposed so as to protrude downward from the bottom of the battery case 33, whereby the vertical dimension of the battery case 33 can be reduced.

The left and right terminal covers 52, 53 forming the housing spaces 52a, 53a of the case-side terminals 55 are disposed so as to be separated from each other in the vehicle width direction. Thus, the battery side terminals 49 are disposed separately from the case side terminals, and the operating lever 36 is disposed at the center in the vehicle width direction, so that the operating lever can be operated similarly from either of the left and right sides of the vehicle body, and in addition, a space for disposing the link mechanism L that links the operating lever 36 and the case side terminals 55 can be secured.

In the present embodiment, the step-down regulator 57 is disposed by utilizing a space secured between the left terminal cover 52 and the right terminal cover 53. In other words, the step-down regulator 57 is disposed between the left and right case-side terminals 55 below the lower case 35. This can improve the layout efficiency and shorten the harness connected to the step-down regulator 57. Further, since the traveling wind passing through the inside of the bottom cover 14 is formed between the left terminal cover 52 and the right terminal cover 53, the down regulator 57 can be efficiently cooled.

Referring to fig. 10, the link mechanisms L are arranged in a pair in the front and rear of the front and rear surfaces of the battery case 33. This enables the case-side terminals 55 to be stably moved up and down. Further, by disposing the link mechanism L in front of and behind the battery case 33, the vehicle width direction dimension around the battery case 33 can be reduced, and the link mechanism L can be protected even when an external force is applied from the vehicle body side. The link mechanism L has a bilaterally symmetrical structure with the center in the vehicle width direction as the center, and can synchronize the operations of the left and right case side terminals 55 and can satisfactorily move the terminals up and down by one operation lever.

The link mechanism L has a structure in which the terminal support arm 70 supporting the case side terminal 55 is moved up and down by a link arm 72 coupled to the lower end portion of the operating lever 36. The link arm 72 is pivotally supported on the base plate 75 via a third shaft 73 functioning as a fulcrum. The end portion of the link arm 72 on the vehicle width direction center side is supported by the operating lever 36 via a first shaft 36g that functions as a point of force. On the other hand, an end portion of the link arm 72 on the outer side in the vehicle width direction is supported by the terminal support arm 70 via a second shaft 71 functioning as an operating point. In the present embodiment, the third shaft 73 is provided closer to the second shaft 71 than the center of the link arm 72, thereby increasing the lever ratio of the link mechanism L and reducing the operation load of the operation lever 36. A support tube 58 fixed to a support stay F10 provided on the lower surface of the cross tube F5 is disposed in front of the left terminal cover 52 and the right terminal cover 53.

Fig. 11 is a partially enlarged view of fig. 3. A support plate F12 for swingably supporting the power unit P to the frame via the link 18 is provided at a lower rear end portion of the base frame F3 at a position below the pivot shaft 19b of the side bracket 19.

As described above, the battery B is housed in the battery case 33 so as to be inclined rearward, and the upright wall portion 34a constituting the upper edge of the battery case 33 is formed in a shape inclined forward and downward. At this time, if the battery B is pulled out upward to some extent, the battery B can be inclined obliquely forward to the outside in the vehicle width direction while being in contact with the upper edge of the upright wall portion 34a, and the battery B can be removed without being lifted up even in a state where the upright state of the battery B is maintained, so that the work load can be reduced. On the other hand, when battery B is inserted, if the side surface of battery B is raised to a position where it abuts against the upper edge of upright wall portion 34a, the insertion operation can be continued with the weight of battery B remaining in upright wall portion 34a, and therefore, the work load can be reduced.

As described above, the pivot shaft 19b of the side bracket 19 is disposed at a position where the rising frame F4 bulges outward in the vehicle width direction. This position is a position housed within the front-rear length of battery B when viewed from the vehicle body side. Thus, the side bracket 19 is disposed near the battery B as a heavy object, thereby reducing the load applied to the pivot shaft 19B.

The pivot shaft 19b is provided at a position below the rising frame F4. Thus, the side stand 19 that supports the battery case 33 at a position on the outside in the vehicle width direction improves the stability during parking, and the side stand 19 supports the upright frame F4 at a position below the upright frame F4, thereby suppressing the overall length of the side stand 19.

The pivot shaft 19b is disposed at the same height as the low bottom plate 17, and when the side stand 19 is stored, the direction of the side stand 19 is along the direction of the upper surface of the low bottom plate 17. Thus, the stored side bracket 19 is positioned at the same height as the low floor 17, and thereby the unfolding and storing operation in the riding state is facilitated. Further, since the pivot shaft 19b is provided at a position overlapping the case-side terminals 55 when viewed from the vehicle body side, the case-side terminals 55 can be protected by the pivot shaft 19b and the rising frame F4 that fixes the pivot shaft 19b even when an external force is applied from the vehicle width direction outside.

PCU32 as a heavy object is disposed in proximity to the upper rear portion of battery case 33, and junction box 80 to which a plurality of high-voltage harnesses are connected is disposed below the PCU. Further, a down-regulator 57 is disposed in proximity to a lower portion of the battery case 33, a pair of front and rear link mechanisms L (see fig. 10) are disposed in front of and behind the battery case 33, and a contactor 46 is disposed in front of the front link mechanism L. In this way, by arranging a plurality of electric components in a concentrated manner around the battery case 33, in other words, around the pivot shaft 19b of the side stand 19, the stability during parking can be improved. Further, by not disposing electric components on the sides of the battery case 33, the amount of bulging of the upright frame F4 outward in the vehicle width direction is suppressed, and an increase in the dimension in the vehicle width direction is prevented.

Fig. 12 is a partially enlarged perspective view of the electric motorcycle 1 as viewed from the left rear. The side stand 19 is provided with the pivot shaft 19b at a position below the upright frame F4, so that the side of the battery case 33 having a large weight can support the vehicle body while suppressing the overall length of the stand lever portion. Thus, even when a heavy load is placed on the rear carrier 40, the vehicle can be stably parked by the side bracket 19. A stopper 19d for limiting the storage position of the side holder 19 is provided behind the pivot shaft 19 b.

As described above, the cover member 21 covering the rear lower portion of the battery case 33 is provided with: a wide portion 21a, the wide portion 21a being located above the stored side bracket 19; and a narrow portion 21b connected to a lower portion of the wide portion 21a, the narrow portion 21b having a smaller dimension in the vehicle width direction than the wide portion 21 a. Thus, by providing the narrow portion 21b that enlarges the distance between the cover member 21 and the side stand 19 in the range in which the side stand 19 swings, the possibility that the foot touches the cover member 21 when the side stand 19 is operated can be reduced, and the operability of the side stand 19 can be improved.

Fig. 13 is a bottom view of the electric motorcycle 1 with the exterior member removed. The storage case 31, which is sandwiched by the bottom frame F3 and stores the sub-battery BS, is disposed offset to the left in the vehicle width direction, and the interlocking mechanism 15a, which operates the front and rear brakes in accordance with the operation of the brake pedal 15, is disposed on the right in the vehicle width direction of the storage case 31. The wire harness 81 connected to the sub-battery BS, the fuse box, and the like protrudes from the bottom of the housing case 31 and is guided rearward. A lock lever 15b for holding the brake pedal 15 in an operating state is disposed behind the interlocking mechanism 15 a. A rail member F13 for supporting the lower plate 17 from below is disposed behind the storage case 31.

The link 18 supported between the power unit P and the support plate F12 is disposed at a position overlapping the down-regulator 57 disposed below the battery case 33 when viewed from the bottom of the vehicle body. The down-pressure regulator 57 is arranged such that the cooling fins face the vehicle body lower side, thereby enhancing the cooling effect of the traveling wind. The link 18 is pivotally supported on the support plate F12 so as to be swingable by a shaft passing through a pivot pipe 76 provided at the front end thereof. The left terminal cover 52 and the right terminal cover 53 attached to the lower portion of the battery case 33 are formed in left-right asymmetrical shapes to prevent interference with the link 18 and the high-voltage three-phase harness 82. The return spring 20a of the center stay 20 is supported by the power unit P at a position to the right in the vehicle width direction.

Fig. 14 is a cross-sectional view showing a state of being cut in a substantially horizontal plane so as to pass through the case-side terminal 55. The pivot shaft 19b of the side bracket 19 is disposed at a position where the upright frame F4 bulges outward in the vehicle width direction and at a position approximately at the center in the front-rear direction of the case-side terminal 55, and thus the load on the side bracket 19 can be reduced and stable parking can be achieved.

The cover member 21 covering the lateral rear of the battery case 33 to the rear of the PCU32 improves the convenience of the side bracket 19 by providing the narrow-width portion 21b, and uses the inside of the wide portion 21a as a space for arranging the wire harness. Further, the case-side terminals 55 are separated from each other to the outside in the vehicle width direction and protrude downward from the battery case 33, so that a space is secured below the battery case 33 toward the center in the vehicle width direction, and the support pipe 56, the connecting pipe 59, and the down-regulator 57 that support the battery case 33 from below are disposed in the space, whereby the vehicle body can be downsized.

The form, shape and structure of the frame, shape and structure of the battery case, the operation lever, shape and structure of the pressing holder, shape and structure of the link mechanism, shape and structure of the side bracket, and the like of the electric motorcycle are not limited to the above-described embodiments, and various modifications are possible. Various configurations of the present invention can be applied to a saddle-ride type tricycle, quadricycle, or the like.
