The duct 115 may be formed as a tubular introduction passage by a tubular member, or may be formed as an introduction passage 1152 by a combination of outer walls of a plurality of members constituting the vehicle body 100, for example.
The vehicle body 100 further includes an electric motor 121 and a control device 122. The electric motor 121 is substantially supported by an axle of the rear wheel 102 at a rear end portion of the swing arm 110. The electric motor 121 generates power (rotation) based on the electric power of the mobile battery unit 120, and rotates the rear wheels 102. The electric motor 121 may be a known motor such as a three-phase induction motor. In addition, the electric motor 121 may be expressed as a motor unit, a power unit, or the like, including a reduction gear. Further, the electric motor 121 may be supported by the vehicle body frame, and the power of the electric motor 121 may be transmitted to the rear wheel via a chain, a sprocket, or the like.
The control device 122 is fixed to the vehicle body frame by a fastener or the like, and is disposed between the pair of right and left lower frames 107 in the present embodiment.

< construction of cell and its periphery >
Fig. 2 and 3 are schematic diagrams showing the structure of the mobile battery unit 120, fig. 2 is a perspective view, and fig. 3 is a bottom view.
The mobile battery unit 120 includes a battery case 1200, a battery section 1201, an electrode section 1202, a grip section 1203, a fastening section 1204, and a hole 1206. The battery case 1200 is a substantially rectangular parallelepiped frame defining the outer shape of the mobile battery unit 120, and is formed of, for example, a resin material. The battery unit 1201 is housed inside the battery case 1200, and stores electric power for driving the electric motor 121 and the like. For example, the battery portion 1201 is constituted by one or more battery cells. The electrode portion 1202 is an electrical connection member (battery-side electrical connection member) that is provided on the bottom surface of the battery case 1200 and that can extract power from the battery portion 1201. The electrode portion 1202 includes one or more electrodes or terminals. One end of the wire harness 91 (see fig. 1) is connected to the electrode portion 1202.
The grip portion 1203 is provided on the upper surface of the battery case 1200 and can be gripped by a user. The user can detach (transport) the mobile battery unit 120 from the vehicle body 100 using the grip portion 1203, attach the mobile battery unit 120 to the vehicle body 100, and exchange the mobile battery unit 120 with another mobile battery unit 120.
The hole 1206 is a hole for positioning the electrode portions 911a and 911b with respect to the electrode portion 1202 when the electrode portions 911a and 911b of the wire harnesses 91a and 91b (refer to fig. 4, hereinafter simply referred to as "electrode portions 911" without particular distinction) are connected to the electrode portion 1202. By inserting a guide member 912, which will be described later, into the hole 1206, positioning in a direction parallel to the bottom surface of the battery case 1200 can be performed. The fastening portion 1204 fixes the battery portion 1201 to the bottom surface of the battery case 1200 by a fastening member such as a bolt.
Fig. 4 is a schematic diagram showing a configuration of an electrode portion 911 provided on the vehicle body 100 side and its periphery. In the case of the present embodiment, the electrode supporting member 915 is supported on the supporting member 914, and the electrode portion 911 and the guide member 912 are further supported on the electrode supporting member 915.
The electrode portion 911 is an electric connection member (vehicle-side electric connection member) on the electric vehicle 1 side that can be connected to the electrode portion 1202 of the mobile battery unit 120. By connecting these components, the electric power stored in the battery unit 1201 is supplied to the electric motor 121, the control device 122, and the like via the wire harness 91. The electrode portion 911 includes one or more electrodes or terminals, and in the present embodiment, a plurality of terminal pins 9111 are arranged side by side in the vehicle width direction. In the present embodiment, the electrode portion 911 is provided to be displaceable by a displacement unit 180 described later, and is connected to the electrode portion 1202 by displacing the electrode portion 911 in a state where the mobile battery unit 120 is mounted on the vehicle body 100.
The guide member 912 is a member for positioning when connecting the electrode portion 911 to the electrode portion 1202. By inserting the guide member 912 into the hole 1206, the movement of the support member 914 supporting the electrode portion 911 in the direction parallel to the bottom surface of the battery case 1200 is restricted. Thereby, the movement of the electrode portion 911 in the above-described direction with respect to the electrode portion 1202 is restricted, and therefore the position of the electrode portion 911 with respect to the electrode portion 1202 is aligned.
Fig. 5 is a perspective view showing the structure of the heat radiation member 130. The heat dissipation member 130 is a member for dissipating heat of the mobile battery cell 120, and is formed of a metal material having high thermal conductivity, such as aluminum, iron, or copper. In the case of the present embodiment, the heat dissipation member 130 includes a plate-shaped portion 1301 and a plurality of heat dissipation fins 1302 extending from the plate-shaped portion 1301. Note that since the plurality of radiating fins 1302 have the same configuration, part of the reference numerals are omitted for the sake of easy viewing of the drawings (the same applies to fig. 6 to 9).
The plate-shaped portion 1301 abuts on the mobile battery unit 120 on a surface facing the surface on which the heat dissipation fins 1302 are provided, and the heat of the mobile battery unit 120 is absorbed from the abutting portion. Further, the shape of the plate-shaped portion 1301 can be designed appropriately.
The plurality of heat dissipation fins 1302 are members for dissipating heat absorbed from the mobile battery cell 120. The shape of the heat dissipating fins 1302 may be a known configuration. For example, corrugated or sword-shaped heat dissipating fins may be used.
In addition, in the present embodiment, the plate-shaped portion 1301 of the heat radiation member 130 further includes an inclined portion 1303, a rotation shaft 1305, and a flat portion 1306. These are structures for displacing the heat dissipation member 130. The heat radiation member 130 is made displaceable by a displacement unit 180 described later rotating the heat radiation member 130 about a rotation axis 1305 as a rotation center. In addition, the other configurations will be described together with the operation of the displacement unit 180 in the item < the configuration and operation of the displacement unit >.
Further, the plate-shaped portion 1301 and the plurality of heat dissipating fins 1302 may be integrally formed, or may be different members. In the case of different members, the plate-shaped portion 1301 and the plurality of heat radiating fins 1302 may be fixed to each other by welding, fitting, fastening, or another method.
Fig. 6 is a schematic diagram showing the structure of the mobile battery unit 120 and its surroundings when the mobile battery unit 120 is mounted on the vehicle body 100, and is a cross-sectional view taken along line I-I of fig. 1. In the present embodiment, the heat dissipation member 130 and the electrode portion 911 are configured to be displaceable, but fig. 6 shows a state in which the heat dissipation member 130 is in an operating position in contact with the mobile battery unit 120 and the electrode portion 911 is in a connection position to the electrode portion 1202. Fig. 6 is a schematic diagram, and a part of the configuration is omitted in view of easy visibility.
In the present embodiment, the mobile battery unit 120 is mounted to the vehicle body 100 in the box-shaped housing portion 125. The upper surface of the housing 125 is provided with an upper surface opening 1251 for attaching and detaching the movable battery unit 120. Further, the bottom surface of the housing portion 125 is provided with a bottom surface opening 1252 for avoiding interference with the electrode portion 911, and the side surface of the housing portion 125 is provided with a side surface opening 1253 for avoiding interference with the heat radiation member 130. Through the side opening 1253, at least a portion of the heat dissipation member 130 is disposed outside the receptacle 125 in the operating position.
Further, the introduction passage 1152 formed by the duct 115 passes through both outer sides of the vehicle width direction side surface of the housing portion 125. With this configuration, at least a part of the heat radiation member 130 is disposed on the introduction path 1152 in the operating position. In the present embodiment, the entire heat radiation fin 1302 of the heat radiation member is disposed on the introduction passage 1152. This enables the mobile battery unit 120 to be cooled more efficiently.
In the present embodiment, the mobile battery unit 120 is mounted in a state of being housed in the box-shaped housing portion 125. However, the manner of mounting the mobile battery unit 120 to the vehicle body 100 is not limited to this as long as the vehicle body 100 has a configuration capable of supporting the mobile battery unit 120.
In the present embodiment, the heat radiation member 130 is in contact with the mobile battery unit 120 so as to sandwich the mobile battery unit 120 from the vehicle width direction of the vehicle 1. This makes it possible to easily dispose the heat radiation member 130 in the intake passage 1152 of the traveling wind flowing rearward from the front of the vehicle. Further, in the case of the present embodiment, two mobile battery units 120 are arranged side by side in the front-rear direction. Thus, they can be arranged closer. However, the heat radiation member 130 may be configured to abut against the mobile battery unit 120 so as to sandwich the mobile battery unit 120 from the front-rear direction of the vehicle 1. This enables the vehicle body 100 to be configured compactly in the vehicle width direction. In the present embodiment, two heat dissipation members 130 are provided for one mobile battery cell 120, but one or three or more heat dissipation members 130 may be provided for one mobile battery cell 120.
< construction and action of Displacement Unit >
Fig. 7A to 7C, 8A to 8C, and 9A to 9C are schematic diagrams illustrating the operation of the displacement unit 180. Fig. 7A, 8A, and 9A are views viewed from the front of the vehicle, fig. 7B, 8B, and 9B are views viewed from the right side of the vehicle, and fig. 7C, 8C, and 9C are views viewed from above. Fig. 7A to 7C are diagrams of a case where the heat radiation member 130 is at the retracted position and the electrode portion 911 is at the retracted position, and fig. 8A to 8C are diagrams of a case where the heat radiation member 130 is at the operating position and the electrode portion 911 is at a position between the connection position and the retracted position. Further, fig. 9A to 9C are diagrams of the case where the heat radiation member 130 is in the working position and the electrode portion 911 is in the connection position. In these drawings, a part of the housing 125 and other structures are omitted in view of easy visibility.
The displacement unit 180 is for displacing the heat radiation member 130 between the operating position and the retreat position, and includes a rod 1801, an arm 1802, and a guide member 1803. By displacing the heat radiation member 130 by the displacement unit 180, the mobile battery unit 120 can be attached and detached in a state where the heat radiation member 130 is separated from the mobile battery unit 120. The displacement unit 180 is supported by the vehicle body frame of the vehicle body 100 and the housing portion 125 in a rotatable state, for example, by a rod 1801. In the present embodiment, the displacement unit 180 is configured to displace the electrode portion 911 between the connection position and the retracted position. Therefore, the displacement unit 180 can displace the heat radiation member 130 in conjunction with the electrode portion 911.
The lever 1801 includes a grip portion 1801a for a user to grip and rotate, a rotating portion 1801b connected to both ends of the grip portion 1801a, and a displacement portion 1801c included in the rotating portion 1801b and displacing the heat dissipating member 130. The grip portion 1801a is disposed so as to extend in the vehicle width direction above the mobile battery unit 120 in a state where the mobile battery unit 120 is mounted on the vehicle body 100. Further, at both ends of the grip portion 1801a in the vehicle width direction, turning portions 1801b are connected, respectively. The rotating portion 1801b is rotatably supported by the rotating shaft 1801 d. The rotating shaft 1801d is supported by the housing 125, for example. The displacement portion 1801c included in the rotation portion 1801b presses the plate-shaped portion 1301 of the heat radiation member 130 toward the inside in the vehicle width direction, that is, the side of the mobile battery unit 120, in accordance with the rotation of the rotation portion 1801b, thereby displacing the heat radiation member 130. Thereby, the heat radiation member 130 abuts against the mobile battery unit 120.
The arm 1802 is connected at one end thereof to the lever 1801 via a rotation shaft 1801 e. The arm 1802 is connected to the support member 914 at an end different from the one end via a pivot 1802 a. As a result, when the rotating unit 1801b rotates, the arm 1802 is pulled upward, and the support member 914 and the electrode portion 911 supported thereby are displaced upward. That is, the electrode portion 911 is displaced upward by the lever operation.
The guide member 1803 is a member that restricts the movement of the rotating unit 1802 a. The guide member 1803 has a guide groove 1803a extending in a direction perpendicular with respect to the bottom surface of the mobile battery unit 120. By displacing the rotary unit 1802a along the guide groove 1803a, the electrode unit 911 is displaced in a direction perpendicular to the bottom surface of the mobile battery unit 120. This facilitates connection of the electrode portion 911 to the electrode portion 1202.
In the present embodiment, the support member 914 is supported via the float mechanism 184. The floating mechanism 184 is supported so that the position of the support member 914 can be adjusted in a direction parallel to the bottom surface of the mobile battery unit 120. For example, the floating mechanism 184 supports the support member 914 by the elastic force of an elastic member such as a spring while allowing the support member 914 to move in a direction parallel to the bottom surface of the battery case 1200 when an external force acts on the support member 914. This enables fine adjustment of the position of the support member 914 with respect to the mobile battery unit 120. For example, when the position of the guide member 912 is slightly shifted from the hole 1206, the guide member 912 is inserted after being moved to the position of the hole 1206. Thereby, the terminal pins 9111 connected thereafter can be aligned in the correct positions.
If the lever 1801 is rotated from the state where the heat radiation member 130 is at the retracted position and the electrode portion 911 is at the retracted position shown in fig. 7A to 7C, the lever is pushed to the state where the heat radiation member 130 is at the operating position and the electrode portion 911 is at a position between the connection position and the retracted position shown in fig. 8A to 8C. The displacement portion 1801c presses the inclined portion 1303 of the heat radiation member 130 with the rotation of the rotation portion 1801, thereby displacing the heat radiation member 130 from the retracted position toward the operating position. Then, if the rotating portion 1801 is further rotated and the displacement portion 1801c reaches the flat portion 1306 continuing to the inclined portion 1303, the heat radiation member 130 reaches the operating position and abuts against the mobile battery cell 120. At this time, the electrode portion 911 is also displaced from the retracted position to the connection position, but is positioned between the two positions without reaching the connection position at the time of fig. 8A to 8C. In addition, in the state shown in fig. 8A to 8C, the guide member 912 is not inserted into the hole 1206 either.
Further, if the lever 1801 is further rotated from the state shown in fig. 8A to 8C, the state is shifted to the state shown in fig. 9A to 9C in which the heat radiation member 130 is at the operating position and the electrode portion 911 is at the connection position. Even if the lever 1801 is further rotated from the state of fig. 8A to 8C, the displacement portion 1801C continues to press the flat surface portion 1306, and thus the position of the heat radiation member 130 is maintained at the operating position. On the other hand, the inclined portion 1303 of the heat radiation member 130 is pressed with the rotation of the rotating portion 1801, whereby the heat radiation member 130 is displaced to the operating position. Then, after the positioning of the electrode portion 911 with respect to the electrode portion 1202 is performed by inserting the guide member 912 into the hole 1206, the electrode portion 911 reaches the connection position and is connected to the electrode portion 1202.
As described above, in the present embodiment, when the user operates the displacement unit 180, the heat radiation member 130 and the electrode portion 911 are displaced from the respective retracted positions. Then, first, the heat radiation member 130 reaches the working position, and then, with the heat radiation member 130 in the working position, the electrode portion 911 reaches the connection position. That is, the electrode portion 911 is connected to the electrode portion 1202 in a state where the heat dissipation member 130 is in contact with the mobile battery unit 120. Therefore, the electrode portion 911 and the electrode portion 1202 can be connected in a state in which the positions of the mobile battery cells 120 are fixed by being held by the two heat dissipation members 130, and therefore the electrode portions 911 can be more accurately connected. In particular, in the present embodiment, since the guide member 912 is inserted into the hole 1206 after the heat radiation member 130 is brought into contact with the mobile battery unit 120 to fix the position of the mobile battery unit 120, positioning can be performed with higher accuracy.
In the present embodiment, the heat radiating member 130 for cooling the mobile battery unit 120 and the like are provided on the vehicle body 100 side. Therefore, it is not necessary to provide a structure for cooling on the side of the mobile battery cell 120 that needs to be transported, and therefore the mobile battery cell 120 can be cooled while suppressing an increase in weight on the side of the mobile battery cell 120. Further, since it is not necessary to provide a structure for cooling on the side of the mobile battery unit 120, the battery capacity can be increased accordingly.
In the present embodiment, the displacement unit 180 displaces the heat radiation member 130 in conjunction with the electrode portion 911. However, the above configuration is an example, and other configurations may be adopted. For example, the heat dissipation member 130 and the electrode portion 911 may be configured to be displaceable independently from each other. In the present embodiment, the heat radiation member 130 and the electrode portion 911 are displaced by a mechanical structure, but may be displaced by an electric or hydraulic actuator or the like, or a combination of a mechanical structure and these components may be used. For example, the displacement unit 180 may mechanically displace the electrode portion 911 and displace the heat radiation member 130 by a hydraulic actuator. At this time, the hydraulic actuator may be operated when the lever 1801 of the displacement unit 180 is rotated, so that the displacement of the electrode portion 911 and the displacement of the heat radiating member 130 are interlocked.
