A cover member 21 (shown as a gray colored portion) that shields the traveling wind introduced from the slit 30a of the floor upper cover 28 and the traveling wind flowing inside the under cover 14 is disposed at a position between the under seat cover 30 and the rear fender 22.

Fig. 3 is a left side view of the electric motorcycle 1 with the main exterior member removed. The frame F (hatched portion in the drawing) of the electric motorcycle 1 includes: a main frame F2 extending downward from the head pipe F1 at the center in the vehicle width direction, a pair of left and right bottom frames F3 connected to the lower end of the main frame F2 and bent rearward, a standing frame F4 directed upward and rearward from the rear end of the bottom frame F3, and a pair of left and right rear frames F6 connected to the standing frame F4 and extending rearward. A lateral pipe F5 that connects the left and right standing frames F4 to each other is connected to the front portion of the standing frame F4.

The steering column 38 is rotatably journaled to the head pipe F1. The steering handle bar 2 is fixed to an upper end portion of the steering column 38, and a bottom bridge 37 for supporting an upper end portion of the front fork 12 is fixed to one lower end portion. A battery case 33 is disposed below the seat 29 to house two mobile batteries B that supply electric power to the motor side by side in the vehicle width direction. The battery case 33 is composed of a vertically long lower case 35 that matches the shape of the battery B, and an upper case 34 that is joined to the upper portion of the lower case 35 to form an opening that matches the bottom shape of the seat 29. The seat 29 is pivotally supported by a hinge 44 located at the upper end of the battery case 33 so as to be openable and closable, and functions as an opening/closing cover for the battery case 33. In the figure, the seat 29 in the open state is indicated by a two-dot chain line.

The battery case 33 is housed between the left and right pair of opposite frames F4 behind the lateral tube F5. The under-seat cover 30 (see fig. 1 and 2) extends from the front of the horizontal tube F5 to the side of the left and right standing frames F4 so as to cover the front and side of the battery case 33. A storage case 31 that stores a low-voltage sub-battery BS for supplying electric power to auxiliary devices such as the headlight 9 and electrical components such as fuses is disposed below the low-voltage floor 17. A connecting pipe F7 for connecting the right and left bottom frames F3 to each other to improve rigidity and to protect the housing case 31 is disposed at the lower portion of the bottom frame F3.

Battery B is a substantially rectangular parallelepiped that is elongated in the vertical direction, and is housed in battery case 33 in a state of being slightly inclined rearward with respect to the vertical direction. This can suppress the height of the battery case 33 and reduce the position of the center of gravity, thereby facilitating the handling operation of the battery B. Further, by tilting the battery B, the pulling-out direction (arrow in the drawing) when the battery B is taken out from the battery case 33 is also slightly tilted rearward, but the tilting angle is in a range where the battery B does not interfere with the 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 in which the seat 29 and the under-seat cover 30 are removed, and the left half of the floor upper cover 28 is removed. Fig. 5 is a structural explanatory diagram of the battery case 33 removed from the state of fig. 4.

An operation lever 36 that is held by an operator and moves up and down is disposed between the two batteries B stored in the battery case 33. In a state in which the operation lever 36 is pushed downward to connect the battery-side terminal and the case-side terminal, the pressing holder 42 pivotally supported by the pivot shaft 42a is brought into contact with the upper surface of the battery B with the urging force, whereby the upward and downward movement of the battery B can be suppressed even when a large step is passed during traveling or the like.

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

The standing wall 34a that forms the upper edge of the battery case 33 is formed to be low in front and high in rear so as to follow the shape of the bottom surface of the seat 29. Thus, when the seat 29 is opened, the locking member 43 and the operation lever 36 located at the front position are easily accessible, and the work of pulling out and inserting the battery B is also easy.

The battery case 33 is supported so as to be sandwiched between the left and right standing frames F4. A pair of left and right tandem footrest holders F11 are provided on the standing frame F4, and a lateral tube F5 is disposed at a position in front of and below the pair of left and right tandem footrest holders F4, and the lateral tube F5 is bent in a substantially U-shape protruding upward to connect the left and right standing frames F4.

Referring to fig. 5, a link mechanism L for converting the up-down movement of the operation lever 36 into the up-down movement of the case-side terminal is disposed in a pair in front of and behind the lower case 35 of the battery case 33. A lock cylinder 45 for operating a seat lock mechanism 48 disposed at the upper part of the rear end of the battery case 33 is disposed at a position below the hinge 44 and covered by the under-seat cover 30. The rear cover 41 covers the upper side of the seat lock mechanism 48, and a cable 60 extending from the key cylinder 45 is connected to the left side of the seat lock mechanism 48 in the vehicle width direction. A contactor 46 for turning on or off the power supply to the electric component is disposed below the key cylinder 45. The lateral pipe F5 connects the left and right standing frames F4 to improve the frame rigidity, and has a function of protecting the 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 of the battery case 33. Further, by disposing the contactor 46 at a position close to the battery B, the wire harness connecting the battery B and the contactor 46 can be shortened.

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

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

Fig. 6 is an enlarged partial plan view of the electric motorcycle 1 with the exterior member removed. The two batteries B are arranged in a left-right arrangement, and an operation lever 36 having a grip portion extending in the front-rear direction is arranged at a position 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 front and rear with respect to one battery B. The pressing holder 42 includes: a metallic body 42b pivotally supported by a pivot shaft 42a so as to be pivotable; 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 pivotally supported by the pivot shaft 42a is configured to be pressed by a biasing force applied to one side by the biasing member in a state where the operation lever 36 is pressed, and to be lifted up by the operation lever 36 by lifting the operation lever 36, thereby being raised in the vertical direction.

In the present embodiment, since the pressing holders 42 are provided in a pair in front and rear 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 to be pulled out to the outside in the vehicle width direction, the pressing holders 42 do not interfere with each other, and the battery B can be smoothly removed. This reduces the lifting height required for loading and unloading the heavy battery B, and facilitates the loading and unloading operation by tilting the battery B outward in the vehicle width direction.

The battery-side terminal 49 provided at the bottom of the battery B is disposed at a position closer to the outer side in the vehicle width direction of the battery B. Accordingly, the operation lever 36 for moving the case-side terminal 55 located below the battery-side terminal 49 up and down can be operated similarly from either the left or right side of the vehicle body, and the replacement work of the battery B can be facilitated. Further, by disposing the operation lever 36 separately from the case-side terminal 55, a space for providing the link mechanism L for interlocking the operation lever 36 with the case-side terminal can be ensured.

The rising frame F4 connected to the bottom frame F3 supporting the lower plate 17 from below is formed in a shape that increases in left-right spacing in accordance with the shape of the battery case 33 at the rising portion rising from the bottom frame F3. The pivot shaft 19b of the side bracket 19 of the rising frame F4 supported on the left side in the vehicle width direction is provided at a portion where the rising frame F4 bulges outward in the vehicle width direction. As a result, the side frames 19 are pivotally supported on the vehicle width direction outer side of the frame F, and the ground contact surface is positioned on the vehicle width direction outer side when the side frames 19 are parked, so that the stability of the vehicle body is improved, and the side frames 19 are easily unfolded and stored. A pair of return springs 19a for biasing the side brackets 19 to the expanded state and the housed state are provided on the outer side and the inner side of the side brackets 19.

Fig. 7 is a perspective view of battery case 33 with battery B removed. The battery case 33, which is formed by combining the upper case 34 and the lower case 35, has a housing portion 50 into which two batteries B arranged in the vehicle width direction are inserted. The battery case 33 is formed in a box shape with a bottom open at the upper side, and the rigidity is improved. As a result, battery B is pressed against vertical wall portion 34a of upper case 34 every time battery B is attached and detached, and durability of battery case 33 is improved.

A partition 54 for preventing contact between the left and right batteries B is provided at the bottom of the housing 50. The partition 54 extends upward along the front and rear inner walls of the housing 50 to a height of about half of the lower case 35. According to the partition 54, the two batteries B stored in the battery case 33 can be prevented from contacting each other on the bottom side, and the batteries B can be stably held. In addition, the partition 54 functions as a guide when the battery B is inserted into the battery case 33, and thus 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 portion of the upper case 34. A deep groove 51 capable of accommodating a document or the like is provided between the base 44a and the lock member 43. The deep groove 51 is provided by using a space created by inclining the battery B rearward in the vertical direction.

As described above, the operating lever 36 that is held by the hand of the operator and moves up and down is disposed between the left and right batteries B. When the operation lever 36 is lifted upward, the battery B is in a detachable state from the battery case 33, whereas when the operation lever 36 is pressed down, the battery side terminal 49 and the case side terminal 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 front and rear with respect to the left and right storage sections 50. The battery B is a substantially rectangular parallelepiped long in the vehicle body up-down direction, and a surface directed to the vehicle width direction outer side out of 6 surfaces constituting the battery B has a curved shape protruding outward in the vehicle width direction when the vehicle body is viewed from above. This can maximize the battery capacity, and facilitate the insertion operation by easily grasping the insertion direction of battery B. In addition, the surface that comes into contact with the upper end portion of the vertical wall portion 34a of the battery case 33 is curved when the battery B is attached and detached, so that the frictional resistance when the weight of the battery B is left on the upper end portion of the vertical wall portion 34a of the battery case 33 is small, and a smooth attachment and detachment operation can be performed.

When the battery B is stored in the battery case 33, the surface of the battery B on the outer side in the vehicle width direction is disposed close to the standing wall portion 34a of the battery case 33 in a plan view of the vehicle body. As a result, when battery B is lifted upward and pulled out to the outside in the vehicle width direction, and when battery B is stored in battery case 33, the vehicle width direction outer side surface of battery B easily comes into contact with standing wall portion 34a of battery case 33. This makes it possible to carry out the loading and unloading work while keeping the weight of battery B in vertical wall 34a without completely lifting battery B, thereby reducing the work load. As shown in fig. 4, since the standing wall portion 34a is formed to be low in front and high in rear when viewed from the vehicle body side, battery B is easily tilted obliquely forward to the vehicle width direction outer side when battery B is lifted upward and pulled out to the vehicle width direction outer side, and when battery B is stored in battery case 33, and the battery B is easily attached and detached.

Fig. 8 is a perspective view of the operation lever 36. The lever 36 made of synthetic resin or the like has a symmetrical shape in the front-rear direction and the left-right direction. The grip 36a for moving the operation lever 36 up and down and the connecting rod 36e extending downward for operating the link mechanism L are connected by a connecting block 36b having a hollow structure. The lock member 43 engages with the upper surface of the front link block 36b to restrict upward movement of the lever 36.

A square engagement plate 36d for abutting against the lower surface of the pressing holder 42 and standing in the vertical direction when the operation lever 36 is lifted is provided at the substantially center of the connection lever 36e in the up-down direction. A metal stay 36f for supporting a pin (first shaft) 36g connected to the link mechanism L is fixed to the lower end of the connecting rod 36e by insert molding.

Further, between the grip portion 36a and the connecting rod 36e, a pair of isolation portions 36c are provided at positions inside the connecting block 36B, which are interposed between the left and right batteries B when the operating rod 36 is pressed down. This allows the operation lever 36 to function as a partition plate that prevents contact between the two batteries B disposed in proximity and stably holds the two batteries B in a predetermined position.

Fig. 9 is a cross-sectional perspective view showing a state in which 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 having a low front and a high rear when viewed from the vehicle body side. Thus, the lever and the pressing holder 42 are protected by the standing wall portion 34a on the rear side, and the lever 36 and the locking member 43 are easily accessible from the outside in the vehicle width direction on the front side.

The connecting rod 36e of the operation lever 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 disposed in the front and rear of the lower case 35. The partition 54 connected to the bottom of the storage portion 50 extends to a lower portion of the engagement plate 36d when the operation lever 36 is pressed to a predetermined position.

A left terminal cover 52 and a right terminal cover 53 for accommodating a housing-side terminal 55 that moves up and down in response to the operation of the link mechanism L are attached to the lower portion of the lower housing 35. A pair of support pipes 56 for supporting the battery case 33 from below are disposed between the left terminal cover 52 and the right terminal cover 53 at the lower portion of the lower case 35.

The left and right case-side terminals 55 are arranged in accordance with the position of the battery-side terminal 49 arranged on the outer side in the vehicle width direction, and the case-side terminals 55 protrude upward from the bottom of the lower case 35 by pressing down the operation lever 36 and are connected to the battery-side terminal 49, while the operation lever 36 is lifted up to move to a position lower than the bottom of the lower case 35. In this way, by disposing the case-side terminals 55 so as to protrude downward from the bottom of the battery case 33, the vertical dimension of the battery case 33 can be reduced.

The left terminal cover 52 and the right terminal cover 53 forming the

housing spaces

52a, 53a of the case-side terminal 55 are disposed so as to be separated from each other in the vehicle width direction. In this way, the battery side terminal 49 is disposed separately from the case side terminal 55, and the operation lever 36 is disposed at the center in the vehicle width direction so as to be operable similarly from either the left or right side of the vehicle body, and in addition, a space in which the link mechanism L for interlocking the operation lever 36 with the case side terminal 55 is disposed can be secured.

In the present embodiment, the step-down regulator 57 is disposed by using a space secured between the left terminal cover 52 and the right terminal cover 53. In other words, the down regulator 57 is disposed below the lower case 35 between the left and right case-side terminals 55. This can improve layout efficiency and shorten the wire harness connected to the down regulator 57. Further, since the passage of 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 cooled efficiently.

Referring to fig. 10, the link mechanism L is disposed in a pair in front of and behind the front and rear surfaces of the battery case 33. This can stably move the case-side terminal 55 up and down. Further, by disposing the link mechanism L in the front and rear of 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 laterally symmetrical structure centering around the center in the vehicle width direction, 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 lever.

The link mechanism L has a structure in which a terminal support arm 70 for supporting the case-side terminal 55 is moved up and down by a link arm 72 connected to the lower end portion of the operation lever 36. The link arm 72 is swingably supported by the base plate 75 via a third shaft 73 functioning as a fulcrum. The end portion on the vehicle width direction center side of the link arm 72 is supported by the operation lever 36 via a first shaft 36g that functions as a force point. 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 action point. In the present embodiment, the third shaft 73 is provided at a position closer to the second shaft 71 than the center of the link arm 72, so that the lever ratio of the link mechanism L is increased, and the operating load of the operating lever 36 is reduced. Support pipes 58 fixed to support stays F10 provided on the lower surface of the horizontal pipe F5 are disposed in front of the left terminal cover 52 and the right terminal cover 53.

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

As described above, battery B is stored so as to be inclined backward with respect to battery case 33, and standing wall portion 34a constituting the upper edge of battery case 33 is formed in a shape inclined forward and downward. At this time, when battery B is pulled out to a certain extent upward, battery B can be tilted obliquely forward to the outside in the vehicle width direction while being in contact with the upper edge of standing wall portion 34a, and battery B can be detached without lifting while maintaining the standing state of battery B, and the work load can be reduced. In contrast, if the side surface of battery B is raised to a position where it abuts against the upper edge of standing wall portion 34a when battery B is inserted, the insertion operation can be continued while leaving the weight of battery B in standing 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 standing frame F4 bulges outward in the vehicle width direction. This position is a position stored in the front-rear length of battery B when viewed from the side of the vehicle body. By this, the burden imposed on the pivot shaft 19B can be reduced by disposing the side bracket 19 in the vicinity of the battery B as a weight.

The pivot 19b is provided at a position below the standing frame F4. Thus, the stability during parking is improved by the side frames 19 being supported at positions outside the battery case 33 in the vehicle width direction, and the side frames 19 are supported at positions below the standing frame F4, whereby the overall length of the side frames 19 can be suppressed.

The pivot 19b is disposed at the same height as the lower plate 17, and the direction of the side bracket 19 is along the direction of the upper surface of the lower plate 17 when the side bracket 19 is stored. By this, the stored side brackets 19 are positioned at the same height as the lower floor 17, and thus the unfolding and storing operation in the riding state are facilitated. Further, since the pivot shaft 19b is provided at a position overlapping the case-side terminal 55 when viewed from the vehicle body side, the case-side terminal 55 can be protected by the pivot shaft 19b and the standing frame F4 to which the pivot shaft 19b is fixed even when an external force is applied from the vehicle width direction outside.

A PCU32 as a weight is disposed near the rear upper portion of the battery case 33, and a junction box 80 for connecting a plurality of high-voltage harnesses is disposed below the PCU. A down regulator 57 is disposed near the lower portion of the battery case 33, a pair of front and rear link mechanisms L (see fig. 10) are disposed in front and rear of the battery case 33, and a contactor 46 is disposed in front of the front link mechanism L. In this way, by disposing a plurality of electric components in a concentrated manner around the battery case 33, in other words around the pivot 19b of the side bracket 19, stability in parking can be improved. Further, by not disposing electrical components on the side of the battery case 33, the amount of bulging of the standing frame F4 to the outside in the vehicle width direction is suppressed, and an increase in the size in the vehicle width direction is prevented.

Fig. 12 is a partially enlarged perspective view of the electric motorcycle 1 as viewed from the rear left. The side bracket 19 can support the vehicle body to the side of the heavy battery case 33 while suppressing the entire length of the bracket lever portion by providing the pivot 19b at a position below the standing frame F4. Thus, even when a heavy load is placed on the rear carrier 40, the vehicle can be stably stopped by the side frames 19. A stopper 19d for defining the storage position of the side bracket 19 is provided behind the pivot 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, wherein the narrow portion 21b is connected to a lower portion of the wide portion 21a, and the width dimension of the narrow portion is smaller than that of the wide portion 21 a. By providing the narrow portion 21b that enlarges the space between the cover member 21 and the side bracket 19 in the range in which the side bracket 19 swings, the possibility that the foot touches the cover member 21 when operating the side bracket 19 can be reduced, and the operability of the side bracket 19 can be improved.

Fig. 13 is a bottom view of the electric motorcycle 1 with the exterior member removed. The housing case 31 that houses the sub battery BS with the bottom frame F3 interposed therebetween is disposed so as to be offset to the left side in the vehicle width direction, and the interlock mechanism 15a that operates the front and rear brakes in response to the operation of the brake pedal 15 is disposed to the right side in the vehicle width direction of the housing 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 15a. A rail member F13 that supports 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 with the pressure reducing regulator 57 provided below the battery case 33 in a bottom view of the vehicle body. The down regulator 57 is provided with cooling fins facing downward of the vehicle body, thereby improving the cooling effect of the traveling wind. The link 18 is swingably supported by the support plate F12 via a shaft passing through a pivot tube 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 a laterally asymmetric shape to prevent interference with the link 18 and the high-voltage three-phase harness 82. The return spring 20a of the center bracket 20 is supported by the power unit P at a position on 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 rising 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, so that the burden on the side bracket 19 can be reduced and stable parking can be realized.

The cover member 21 covering the side rear of the battery case 33 to the rear of the PCU32 improves convenience of the side brackets 19 by providing the narrow width portions 21b, and uses the inner side of the wide width portions 21a as an arrangement space of the wire harness. Further, by separating the case-side terminals 55 from each other toward the outside in the vehicle width direction and projecting downward of the battery case 33, a space is ensured in the lower portion of the battery case 33 toward the center in the vehicle width direction, and the support pipe 56, the connecting pipe 59, and the pressure reducing regulator 57 that support the battery case 33 from below are disposed in the space, whereby the vehicle body can be made smaller.

The shape, the structure, the operation lever, the shape, the structure, the link mechanism, the shape, the structure, and the like of the side stand of the electric motorcycle are not limited to the above-described embodiments, and various modifications are possible. The various structures of the present invention can be applied to a saddle-ridden three-wheeled vehicle, four-wheeled vehicle, and the like.
