According to the above configuration, the space around the link member, which is a dead zone between the power unit and the vehicle body frame, can be effectively utilized as the arrangement space of the control unit, and the control unit is brought closer to the motor than the configuration in which the control unit is arranged on the vehicle body side, whereby shortening of the electric wire connecting the control unit and the motor can be achieved.

(2) In the embodiment of (1), the control unit (80) may be fixed to the upper surface (73 a) of the link member (70).

According to the above configuration, the lower surface of the control unit can be covered with the link member, so that the control unit can be protected from flying objects such as flying stones flying from below.

(3) In the embodiment (1) or (2), the control unit (80) may be fastened to the link member (70), and an elastic member (87) may be interposed between the control unit (80) and the link member (70).

According to the above configuration, the elastic member absorbs the vibration and deformation of the link member, and thereby the transmission to the control unit can be suppressed. This can suppress the application of external force to the control unit.

(4) In any one of the above aspects (1) to (3), the control unit (80) may include a housing (81) and a control board (82) housed in the housing (81), the housing (81) may be coupled to the link member (70) in a predetermined direction, and the control board (82) may be disposed on an opposite side of a coupling portion of the housing (81) to the link member (70) in the predetermined direction.

According to the above configuration, compared with a configuration in which the control board is disposed on the same side of the joint portion of the housing to which the link member is joined, it is possible to make it difficult for stress applied from the joint portion to the control unit to be transmitted to the control board.

(5) In any one of the above aspects (1) to (4), the electric wire (90) may include: a motor connection unit (91) connected to the stator of the motor (44); and an introduction portion (92) which is introduced into the housing (50) from the control unit (80) and which is connected to the motor connection portion (91), wherein the housing (50) is provided with a partition wall (62), the partition wall (62) defines a connection space (59 a) and an introduction space (59 b), a connection portion which connects the motor connection portion (91) and the introduction portion (92) is disposed in the connection space (59 a), the introduction space (59 b) communicates with the outside of the housing (50) and introduces the introduction portion (92) from the outside of the housing (50), and the introduction portion (92) is inserted into the partition wall (62) via a sealing member (66).

According to the above configuration, when the electric wire is introduced into the wire connection space, the wire introduction portion of the electric wire can be extended from the wire connection space to the wire connection space in a state where the wire connection space is independent from the wire introduction space communicating with the outside. This can prevent the water from adhering to the connection portion of the motor connection portion and the lead-in portion.

(6) In any one of the above aspects (1) to (5), the control unit (80) may include a cooling fin (83) provided on an outer surface and extending in a front-rear direction of the vehicle.

According to the above configuration, the traveling wind can be caused to pass through the gaps of the cooling fins, and therefore the air cooling effect of the control unit can be improved.

(7) In any one of the aspects (1) to (6), the saddle-ride type vehicle may further include: a seat (4) supported by the vehicle body frame (20); and a battery (6) disposed below the seat (4), wherein at least a part of the control unit (80) is disposed below the battery (6), and the battery (6) is disposed in a state in which the longitudinal direction is inclined in the front-rear direction with respect to the up-down direction of the vehicle.

According to the above configuration, compared with a configuration in which the battery is arranged in a state in which the longitudinal direction of the battery is along the up-down direction, a gap with respect to the control unit that is displaced with the swinging of the link member can be ensured. Therefore, the arrangement of the battery can be made suitable for the configuration in which the control unit is fixed to the link member.

Effects of the application

According to the present application, the electric wire connected to the motor for running can be shortened.

As shown in fig. 1, the battery 6 is disposed below the seat 4. At least a part of PCU80 is disposed below battery 6. In the present embodiment, a pair of batteries 6 are disposed in front and rear, and PCU80 is disposed below front battery 6. The batteries 6 are formed in a rectangular parallelepiped shape and are formed in the same structure. The battery 6 is disposed such that the top surface of the installation handle is located above the bottom surface of the installation terminal, and two of the four side surfaces face outward in the vehicle width direction. The battery 6 is formed in a rectangular shape with a top surface and a bottom surface located at both ends in the longitudinal direction in a side view of the vehicle. The battery 6 is disposed so as to be low in front and high in rear, and the longitudinal direction is inclined in the front-rear direction with respect to the up-down direction in a side view of the vehicle. The pair of batteries 6 are arranged parallel to each other, and the bottom surface of the rear battery 6 is arranged above the bottom surface of the front battery 6. Thus, the battery 6 is arranged so as to extend in a front-lower-rear-higher manner from below an imaginary straight line L1 circumscribing the pair of battery 6 in side view. The pair of batteries 6 are wired in series and electrically connected to the PCU80 via an electric wire not shown. In this case, the battery 6 may be connected to the PCU80 via a junction box.

As described above, the motorcycle 1 of the present embodiment includes the PCU80 fixed to the link member 70. According to this configuration, the space around the link member 70, which may be a dead space between the power unit 41 and the vehicle body frame 20, can be effectively utilized as the arrangement space of the PCU80, and the PCU80 can be brought closer to the motor 44 than in a configuration in which the PCU is arranged on the vehicle body side such as the inside of the center tunnel, whereby the three-phase line 90 connecting the PCU80 and the motor 44 can be shortened.

In addition, the PCU80 is fixed to the upper surface 73a of the first link arm 73 of the link member 70. According to this structure, by covering the lower surface of PCU80 with link member 70, PCU80 can be protected from flying objects such as flying stones flying from below.

An elastic member 87 is interposed between the PCU80 and the link member 70. According to this structure, the elastic member 87 can absorb the vibration and deformation of the link member 70, and can suppress the transmission to the PCU80. This can suppress the application of external force to PCU80.

The housing 81 of the PCU80 is coupled with the link member 70 in the up-down direction. The control board 82 is disposed on the opposite side of the housing 81 from the fastening portion 84 in the up-down direction. According to this configuration, compared to a configuration in which the control board 82 is disposed on the same side of the housing 81 as the fastening portion 84, it is possible to make it difficult for stress applied from the joint portion between the housing 81 and the link member 70 to be transmitted to the control board 82.

The three-phase line 90 includes: a motor connection portion 91 connected to a stator of the motor 44; and an introduction portion 92 which is introduced from the PCU80 into the swing frame 50 and which is wired to the motor connection portion 91. The swing frame 50 includes a partition wall 62, and the partition wall 62 defines a connection space 59a in which a connection part of the motor connection part 91 and the introduction part 92 are arranged, and an introduction space 59b which communicates with the outside of the swing frame 50 and introduces the introduction part 92 from the outside of the swing frame 50. The introduction portion 92 is inserted through the partition wall 62 via the seal member 66. According to this configuration, when three-phase wire 90 is drawn into wire connecting space 59a, lead-in portion 92 of three-phase wire 90 can be extended from lead-in space 59b to wire connecting space 59a in a state where wire connecting space 59a is independent from lead-in space 59b communicating with the outside. This can prevent the wire portions of the motor connection portion 91 and the introduction portion 92 from being wet.

The PCU80 includes cooling fins 83 provided on an outer surface and extending in the front-rear direction. With this configuration, the traveling wind can pass through the gaps of the cooling fins 83, and thus the air cooling effect of the PCU80 can be improved.

At least a part of PCU80 is disposed below battery 6. The battery 6 is disposed in a state in which the longitudinal direction is inclined in the front-rear direction with respect to the vertical direction. According to this configuration, compared to a configuration in which the battery 6 is arranged in a state in which the longitudinal direction of the battery 6 is along the up-down direction, a gap with respect to the PCU80 that is displaced in accordance with the swinging of the link member 70 can be ensured. Therefore, the battery 6 having a structure suitable for fixing the PCU80 to the link member 70 can be arranged.

Second embodiment

Next, a second embodiment will be described with reference to fig. 7. Fig. 7 is a left side view of the motorcycle according to the second embodiment.

As shown in fig. 7, a motorcycle 1A according to a second embodiment differs from the first embodiment in that a pair of battery cells 6 under a seat 4 are arranged so that their longitudinal directions are inclined in the front-rear direction with respect to the up-down direction in a side view of the vehicle. The configuration other than the following description is the same as that of the first embodiment.

The pair of batteries 6 are arranged parallel to each other, and the bottom surface of the rear battery 6 is arranged above the bottom surface of the front battery 6. Thus, the battery 6 is arranged so as to extend in a front-lower-rear-higher manner from below an imaginary straight line L2 circumscribing the pair of battery 6 in a side view. According to this configuration, as in the first embodiment, the battery 6 can be arranged appropriately in a configuration in which the PCU80 is fixed to the link member 70.

The present application is not limited to the above-described embodiment described with reference to the drawings, and various modifications are conceivable within the technical scope thereof.

For example, in the above-described embodiment, the present application is applied to a motorcycle, but the application scope of the present application is not limited thereto. The present application is applicable to all saddle-ride type vehicles in which a driver rides on a saddle-ride type vehicle body including a motor tricycle in addition to a motor bicycle. The present application is applicable not only to an electric vehicle having only a motor as a power source as in the above-described embodiment, but also to an electric hybrid vehicle having an engine and a motor as power sources.

In the above embodiment, the PCU80 is disposed above the link member 70, but the structure is not limited thereto. The PCU may be disposed below the link member or may be disposed so as to be sandwiched by the link member from both sides in the vehicle width direction.

In the above embodiment, the rubber bushing externally inserted to the fastening member 86 is inserted as an elastic member between the PCU80 and the link member 70, but the structure of the elastic member is not limited to this. The elastic member may be interposed between the bottom surface of the case of the PCU and the link member, for example.

In the above embodiment, the PCU80 is exposed downward through between the pair of first link arms 73 of the link member 70, but the structure is not limited thereto. For example, the link member may be provided with a member that covers the PCU from below, in addition to the link arm.

In the above embodiment, the seal member 66 is provided in the partition wall 62 in the swing frame 50, but the structure is not limited thereto. For example, the sealing member may close the opening at the front end of the swing frame.

The components in the above embodiments may be appropriately replaced with known components within a range not departing from the gist of the present application.
