Excessive temperature rise in the battery and charger is suppressed, and the operations of the battery and charger are stabilized.

Hereinafter, this embodiment will be described in detail with reference to the accompanying drawings. In this embodiment, the straddle-type vehicle is a scooter type straddle-type vehicle, but the straddle-type vehicle may be another electric or hybrid type straddle-type vehicle. Further, in the following figures, an arrow FR indicates the front of the vehicle, an arrow RE indicates the rear of the vehicle, an arrow L indicates the left side of the vehicle, and an arrow R indicates the right side of the vehicle. FIG. 1 is a left side view of a straddle-type vehicle. FIG. 2 is a right side view of the vehicle body frame and electrical components.

As shown in FIG. 1, a scooter-type straddle-type vehicle 1 is constructed by attaching various covers as vehicle body exteriors to an underbone type vehicle body frame 10 (see FIG. 2). A front frame cover 21 is provided on the front side of the vehicle, and a leg shield 22 is provided on the rear side of the front frame cover 21 to protect the leg of the passenger. A footboard 23 extends rearward from the lower end of the leg shield 22, and a rear frame cover 24 is provided behind the footboard 23. The leg shield 22 and the footboard 23 form a space for resting the rider's feet in front of the rider seat 41.

A handle 32 is provided above the front frame cover 21, and a front wheel 34 is rotatably supported below the front frame cover 21 via a pair of front forks 33. A rider seat 41 and a pillion seat 42 are provided above the rear frame cover 24, and a swing arm 43 (see FIG. 5) covered with a swing arm cover 47 is provided below the rear frame cover 24. A rear wheel 44 is rotatably supported at the rear part of the swing arm 43, and the rear part of the swing arm 43 is connected to the vehicle body frame 10 (support frame 15) via a suspension 45.

As shown in FIG. 2, the front portion of the vehicle body frame 10 is provided with a head pipe 11 into which a steering shaft (not shown) is inserted. A front frame 12 extends downward from the head pipe 11, and a pair of lower frames 13 extends rearward from the lower part of the front frame 12. A pair of rear frames 14 rise diagonally rearward from approximately the middle portions of the pair of lower frames 13, and a pair of support frames 15 rise diagonally rearward from the rear portions of the pair of lower frames 13. The rear portions of the pair of support frames 15 are connected to the rear portions of the pair of rear frames 14 from below.

An installation space A1 (see FIG. 3) for each electrical component is formed inside the pair of rear frames 14 and the pair of support frames 15, that is, inside the rear frame cover 24. Above the installation space A1, there is a charger 55 that converts power source power into DC power of a predetermined voltage, a DC/DC converter (other electrical components) 65 that steps down the voltage of the DC power, and a DC power that charges the stepped down DC power. A battery 51 (see FIG. 3) is installed. An electric power unit 75 connected to the battery 51 via an inverter 71 that converts DC power to AC power is installed below the installation space A1. The inverter 71 is installed between the pair of lower frames 13 in front of the electric power unit 75.

Furthermore, the pair of rear frames 14 and the pair of support frames 15 are connected in the front-rear direction via a pair of pivot brackets 16, respectively. The swing arm 43 is connected to the pair of pivot brackets 16 so as to be swingable in the vertical direction, and the swing arm cover 47 is attached to the swing arm 43 as described above. The swing arm cover 47 covers the sprocket (not shown) and chain 46 (see FIG. 1) of the electric power unit 75, and the driving force of the electric power unit 75 is transmitted to the rear wheel 44 via the sprocket and chain 46.

Generally, the vehicle body of the straddle-type vehicle 1 is generally thin in the vehicle width direction and long in the vehicle length direction. The rear frame cover 24 extends along the outer periphery of the rider seat 41 when viewed from above, and the installation space A1 inside the rear frame cover 24 is formed such that the dimension in the vehicle width direction decreases from the rear of the vehicle toward the front of the vehicle. (See Figure 4). Since a plurality of electrical components for charging are installed in this narrow installation space A1, heat generated from each electrical component tends to be trapped inside the rear frame cover 24. In order to stabilize the operation of each electrical component, a structure that suppresses excessive temperature rise of each electrical component is desired.

Therefore, in the saddle type vehicle 1 of this embodiment, the shape and installation of the plurality of electrical parts for charging are devised, and the battery 51, charger 55, etc. are installed in the narrow installation space A1 inside the rear frame cover 24. Multiple electrical components are installed. At this time, charger 55 and battery 51 are adjacent to each other in installation space A1 so that charger 55 and battery 51 face each other over a wide area. Excessive temperature rise in charger 55 and battery 51 is suppressed by heat exchange between charger 55 and battery 51. Moreover, by flowing cooling air into the installation space A1, hot air in the installation space A1 is discharged to the outside.

The installation layout of electrical components within the installation space will be described below with reference to FIGS. 3 to 5. FIG. 3 is a perspective view showing the installation layout of electrical components within the installation space. FIG. 4 is a top view showing the installation layout of electrical components within the installation space. FIG. 5 is a right side view showing the installation layout of electrical components within the installation space. Further, some cables in FIGS. 3 to 5 are omitted.

As shown in FIGS. 3 to 5, the installation space A1 (see FIG. 1) inside the rear frame cover 24 is formed such that the dimension in the vehicle width direction decreases from the rear of the vehicle toward the front of the vehicle. The installation space A1 accommodates a battery unit 50 in which a battery 51, a charger 55, and a DC/DC converter 65 are unitized via a plate-shaped bracket 77. The battery unit 50 is formed so that the battery 51, the charger 55, and the DCDC converter 65 can be integrated into the installation space A1 by shaping and installing the battery 51, the charger 55, and the DC/DC converter 65 to suit the installation space A1. There is.

Similarly to the installation space A1, the battery unit 50 is formed such that the dimension in the vehicle width direction decreases from the rear of the vehicle toward the front of the vehicle when viewed from above. With the pair of main surfaces of the plate-like bracket 77 facing in the vehicle width direction, the battery 51 is fixed to one main surface of the plate-like bracket 77, and the charger 55 is fixed to the rear of the other main surface of the plate-like bracket 77. is fixed, and a DCDC converter 65 is fixed to the front part of the other main surface of the plate-shaped bracket 77. When the installation space A1 is divided into three parts in the vehicle width direction, the battery 51 is positioned from the center to the left side, the charger 55 is positioned on the right rear side, and the DCDC converter 65 is positioned on the right front side.

The battery 51 is formed by housing a plurality of cells (single cells) inside a pair of left and right case halves 52 and 53. The left case half 52 is positioned on the left side of the installation space A1, and the right case half 53 is positioned at the center of the installation space A1. The left case half 52 is formed into a trapezoidal box shape when viewed from above, and the right case half 53 is formed into a rectangular box shape when viewed from above. The total dimension of the left and right case halves 52, 53 in the vehicle width direction is smaller than the dimensions of each case half 52, 53 in the vehicle length direction and height direction. The battery 51 is installed in the installation space A1 so that the lateral direction faces the vehicle width direction.

Further, a swing bracket 54 that supports the rider seat 41 (see FIG. 1) is provided at the upper front end portion of the case half 53 on the right side of the battery 51. The rider seat 41 is supported from below by a battery 51 inside the rear frame cover 24 via a swing bracket 54. By opening the rider seat 41 using the front end portion of the battery 51 as a fulcrum, the battery unit 50 in the installation space A1 is exposed to the outside. The height dimension of the front half of the battery 51 is smaller than the height dimension of the rear half of the battery 51 so as to avoid the electric power unit 75.

A charger 55 is installed on the right side of the battery 51 in the installation space A1 so that its width direction faces the vehicle width direction and its length direction faces the height direction. The charger 55 is formed in the shape of a rectangular parallelepiped box. Charger 55 is adjacent to the rear of battery 51 in the vehicle width direction. A cooling case 61 that partially covers the charger 55 is attached to the right side 56 of the charger 55, and a large number of heat radiation fins 58 are provided in front of the cooling case 61. A cooling fan 62 is provided at the bottom of the cooling case 61 for feeding outside air into the right side 56 of the charger 55. The charger 55 is effectively cooled by the cooling fan 62 and the large number of heat radiation fins 58.

A DCDC converter 65 is installed in front of the charger 55 in the installation space A1 so that the width direction thereof faces the vehicle width direction and the length direction faces the height direction. The DCDC converter 65 is formed in the shape of a rectangular parallelepiped box. The DCDC converter 65 is adjacent to the front part of the battery 51 in the vehicle width direction, and is adjacent to the upper half of the charger 55 in the vehicle length direction. A large number of radiation fins 69 are provided on the right side of the DCDC converter 65. The dimensions of the DCDC converter 65 in the height direction, vehicle length direction, and vehicle width direction are smaller than the dimensions of the charger 55 in the height direction, vehicle length direction, and vehicle width direction.

An electric power unit 75 is installed below the battery 51 in the installation space A1. Since the heavy objects such as a battery 51, a charger 55, a DC/DC converter 65, and an electric power unit 75 are installed below the rider seat 41, the steering stability of the straddle-type vehicle 1 (see FIG. 1) is improved. . An inverter 71 is installed in front of the electric power unit 75. Since the inverter 71 is installed near the battery 51 and the electric power unit 75, the power transmission cable 72 from the battery 51 to the inverter 71 and the power transmission cable 73 from the inverter 71 to the electric power unit 75 are shortened.

The power transmission cable 81 has one end connected to the charger 55 and the other end connected to the battery 51 and the DC/DC converter 65. The power transmission cable 82 has one end connected to the charger 55 and the other end connected to the charging port 70 (see FIG. 2) located at the front of the vehicle. The middle portion of the power transmission cable 82 extends in the front-rear direction on the right side of the vehicle, and passes on the right side of the inverter 71 and the electric power unit 75. Further, a wire harness 89 connected to various electrical devices of the vehicle including power supply related devices such as the battery 51, charger 55, and DC/DC converter 65, vehicle control device, lighting device, etc. is arranged along the power transmission cable 82. It extends in the front-rear direction on the right side of the vehicle and passes on the right side of the inverter 71 and the electric power unit 75. Connection portions 83 and 84 for power transmission cables 81 and 82 are formed on the top surface of charger 55. The front part of the right side of the battery 51 has a pair of connection parts 85 facing right side, and the connector 86 of the power transmission cable 81 and the connector 91 of the wire harness 89 are connected to the pair of connection parts 85 from the right side. Connected. The front side surface of the DCDC converter 65 has a connecting portion 87 facing forward, and a connector 88 of the power transmission cable 81 and a connector 90 of the wire harness 89 are connected to the connecting portion 87 from the front.

As described above, the installation space A1 inside the rear frame cover 24 has a dimension in the vehicle width direction that decreases from the rear of the vehicle toward the front of the vehicle. The battery 51 is formed in a shape that fits on the left side from the center of the installation space A1, and the charger 55 is formed in a size that fits on the right rear side of the installation space A1. Therefore, the battery 51 and the charger 55 are installed adjacent to each other in the vehicle width direction in the installation space A1, which has a small dimension in the vehicle width direction. A small DC/DC converter 65 is installed in the remaining dead space in front of the charger 55. In this way, the battery 51, charger 55, and DCDC converter 65 are compactly housed in the installation space A1.

Next, a cooling structure for the battery and charger will be described with reference to FIGS. 6 and 7. FIG. 6 is an image diagram of heat exchange between the battery and the charger. FIG. 7 is a diagram showing the flow of cooling air within the installation space.

As shown in FIG. 6, the shorter sides of the battery 51 and the charger 55 are oriented toward the vehicle width direction so that the facing area of the battery 51 and the charger 55 is the largest, and the battery 51 and the charger are placed in the installation space A1. A container 55 is installed adjacently. More specifically, the left side of the charger 55 is fixed to the right side of the battery 51 via a plate-shaped bracket 77. The battery case of the battery 51, the plate-shaped bracket 77, and the charging case of the charger 55 are each made of a metal material or the like with high thermal conductivity. Thereby, heat exchange is performed between the battery 51 and the charger 55 via the plate-shaped bracket 77.

The battery case of the battery 51 is formed larger than the charging case of the charger 55. Therefore, the heat capacity of the battery case is larger than that of the charging case, and the temperature of the battery 51 is less likely to rise than that of the charger 55. While the battery 51 is being charged, heat generated by the charger 55 is absorbed by the battery case as shown by arrow A, and an excessive temperature rise in the charger 55 is suppressed. The battery case absorbs the heat generated by the charger 55, but since the battery case has a large heat capacity, the temperature of the battery 51 does not rise excessively. Therefore, excessive temperature rise of the charger 55 and battery 51 can be suppressed and the operation can be stabilized.

While the straddle-type vehicle 1 is running, the heat generated by the battery 51 is absorbed by the charging case as shown by arrow B, and the temperature rise of the battery 51 is suppressed. Although the charging case absorbs the heat generated by the battery 51, the heat capacity of the battery case itself is large and the temperature does not easily rise, so high temperature is not transmitted from the battery case to the charger 55, and the temperature of the charger 55 does not rise excessively. . Note that since the charger 55 is stopped while the straddle-type vehicle 1 is running, the heat generated by the battery 51 does not adversely affect the operation of the charger 55. Therefore, excessive temperature rise of the charger 55 and battery 51 can be suppressed and the operation can be stabilized.

Similarly to the charger 55, the excessive temperature rise of the DCDC converter 65 is also suppressed. The battery 51 and the DCDC converter 65 are installed adjacent to each other so that the opposing area between the battery 51 and the DCDC converter 65 is maximized. The converter case of the DCDC converter 65 is also made of a metal material with high thermal conductivity. While the battery 51 is being charged, the heat generated by the DCDC converter 65 is absorbed by the battery case, and an excessive temperature rise in the DCDC converter 65 is suppressed. While the straddle-type vehicle 1 is running, the heat generated by the battery 51 is absorbed by the converter case, and the temperature rise of the battery 51 is suppressed.

As shown in FIG. 7, the rear side of the rear frame cover 24 is open, and the installation space A1 inside the rear frame cover 24 is connected to the surrounding space A2 of the rear wheel 44. A charger 55 is installed on the rear wheel 44 side of the installation space A1, and the right side of the charger 55 is partially covered by a cooling case 61. A cooling fan 62 is provided at the lower part of the cooling case 61 to draw outside air into the cooling case 61 from the peripheral space A2 of the rear wheel 44. An opening (not shown) is formed in the front surface of the cooling case 61, and a large number of radiation fins 58 are arranged in the height direction on the right side surface 56 of the charger 55 along the front surface 63 of the cooling case 61.

A large number of radiation fins 58 extend obliquely from the cooling fan 62 side to the DC/DC converter 65 side, that is, from the rear of the vehicle toward the front of the vehicle. A space between adjacent radiation fins 58 is a flow path that guides the cooling air blown out from the opening of the cooling case 61 toward the DCDC converter 65 . In this way, the heat radiation fins 58 function not only as heat radiation members but also as cooling air guide members. The DCDC converter 65 is installed in front of the charger 55, and a large number of heat radiation fins 69 are formed on the right side of the DCDC converter 65. A large number of radiation fins 69 extend horizontally from the rear of the vehicle toward the front of the vehicle.

While the battery 51 is being charged, the cooling fan 62 is driven, and outside air taken in from the space A2 around the rear wheel 44 is sent into the cooling case 61 as cooling air. The cooling air inside the cooling case 61 flows along the right side surface 56 of the charger 55 while absorbing the heat of the charger 55, and flows between the many heat radiation fins 58 through the opening of the cooling case 61. The cooling air between the radiation fins 58 is guided toward the DCDC converter 65 while absorbing the heat of the radiation fins 58 . A portion of the cooling air after passing through the radiation fins 58 is blown onto the right side of the DCDC converter 65, and the heat of the DCDC converter 65 is absorbed.

The warmed cooling air goes around the charger 55 and is discharged from the rear side of the rear frame cover 24 to the space A2 around the rear wheel 44. The hot air trapped in the installation space A1 is discharged to the space A2 around the rear wheel 44, and outside air is taken into the installation space A1 as cooling air from the space A2 around the rear wheel 44, replacing the hot air in the installation space A1 with the outside air. ing. In this way, the charger 55 is effectively cooled by the cooling air and the heat radiation fins 58, and the hot air inside the rear frame cover 24 is discharged to the outside, thereby suppressing an excessive temperature rise in the charger 55. It is being

Further, the charger 55 is formed to have a large dimension in the height direction, and the lower end of the charger 55 is positioned below the upper end of the rear wheel 44. By bringing the charger 55 closer to the surrounding space A2 of the rear wheel 44, outside air enters the installation space A1 from the surrounding space A2, making it easier for the outside air to come into contact with the charger 55. Furthermore, the cooling fan 62 at the lower part of the cooling case 61 facilitates sending outside air into the cooling case 61 from the space A2 around the rear wheel 44. In this way, by making the charger 55 vertically elongated and bringing it closer to the rear wheel 44, the cooling effect of the charger 55 is enhanced.

As described above, according to the present embodiment, the battery 51 and the charger 55 are housed adjacently in the vehicle width direction inside the rear frame cover 24, which has a narrow dimension in the vehicle width direction. Inside the rear frame cover 24, the battery 51 and the charger 55 face each other over a large area, so that heat exchange is efficiently performed between the battery 51 and the charger 55. Further, the charger 55 is cooled by the cooling fan 62 and the radiation fins 58, and the hot air inside the rear frame cover 24 is discharged to the outside by the cooling air. This suppresses excessive temperature rise of the battery 51 and charger 55 in the narrow installation space A1 inside the rear frame cover 24, and stabilizes the operation of the battery 51 and charger 55.
