Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, when a mechanic or a user with maintenance skills performs maintenance or repair on a cooling target device such as a motor or a water pipe, the water pipe is removed from the cooling target device. At this time, these users must be careful not to get water on the high-voltage electrical wiring from the removed water pipe or the cooling target device, which has been a considerable work burden.

[0006] An object of the present invention is to reduce the work burden of maintenance or repair of a water pipe of a vehicle.

Means for Solving the Problems

[0007] The vehicle disclosed herein comprises one or more electrical devices, one or more high-voltage electrical wiring connected to the electrical devices, and one or more water pipes through which cooling water for cooling the electrical devices flows. A predetermined portion of the water pipe and the high-voltage electrical wiring are arranged at a distance of at least a first predetermined distance from each other.

[0008] The electrical equipment may have a joint to which the water piping is detachably connected. The joint and the high-voltage electrical wiring may be located at a distance greater than or equal to the first predetermined distance from each other.

[0009] According to the above vehicle, the water piping and the high-voltage electrical wiring are separated by a predetermined distance or more, or the joint and the high-voltage electrical wiring are separated by a predetermined distance or more. Therefore, when the water piping is removed from the joint for maintenance or repair, water is less likely to come into contact with the high-voltage electrical wiring. Since water is less likely to come into contact with the high-voltage electrical wiring, the workload for maintenance or repair of the water piping is reduced for mechanics and users with maintenance skills.

[0010] The first predetermined distance may be 150 mm.

[0011] As a result, the designated parts or joints of the water piping are sufficiently far from the high-voltage electrical wiring, making it less likely for water to come into contact with the high-voltage electrical wiring.

[0012] The predetermined portion of the water piping or the joint and the high-voltage electrical wiring may be spaced apart in the left-right direction of the vehicle.

[0013] For example, even if water spills when the water pipe is removed from the joint, the water will fall downwards. According to the above, since the designated part of the water pipe or joint and the high-voltage electrical wiring are separated in the left-right direction of the vehicle, it is possible to more reliably prevent water from coming into contact with the high-voltage electrical wiring.

[0014] The predetermined portion or joint of the water piping and the high-voltage electrical wiring may be arranged at a distance of at least a second predetermined distance from each other in the left-right direction of the vehicle.

[0015] As a result, the designated parts or joints of the water piping and the high-voltage electrical wiring are far apart in the left-right direction of the vehicle, making it less likely for water to come into contact with the high-voltage electrical wiring.

[0016] The water piping may have a first piping portion extending in the longitudinal direction of the vehicle. The high-voltage electrical wiring may have a first wiring portion extending in the longitudinal direction of the vehicle. With respect to the left-right direction of the vehicle, vehicle components may be arranged between the first piping portion and the first wiring portion.

[0017] As a result, even if water leaks from the first piping section, the vehicle components are positioned between the first piping section and the first wiring section, making it less likely for water to come into contact with the first wiring section.

[0018] The aforementioned vehicle component may include a battery.

[0019] The predetermined portion of the water piping or the joint and the high-voltage electrical wiring may be separated from each other by a second predetermined distance or more in the left-right direction of the vehicle, and by a third predetermined distance or more in the up-down direction of the vehicle.

[0020] The predetermined portion of the water piping or the joint may be located below the high-voltage electrical wiring in the vertical direction of the vehicle.

[0021] This means that, for example, if water spills from the joint or water pipe when the water pipe is removed from the joint, the high-voltage electrical wiring is located higher than the joint, making it less likely for water to get on the high-voltage electrical wiring.

[0022] More than 60% of the water piping and more than 60% of the high-voltage electrical wiring may be arranged at a distance of at least a first predetermined distance from each other.

[0023] More than 60% of the water pipe portion and more than 60% of the high-voltage electrical wiring portion may be arranged at a distance of at least a second predetermined distance from each other in the left-right direction of the vehicle.

[0024] The electrical equipment may include one or more driving motors.

[0025] The vehicle may include a pair of left and right front wheels and a pair of left and right rear wheels. The electrical equipment may include a front motor connected to the front wheels to drive the front wheels and a rear motor connected to the rear wheels to drive the rear wheels. The front motor may have a first joint detachably connected to the water pipe. The rear motor may have a second joint detachably connected to the water pipe. The high-voltage electrical wiring may be arranged on either the left or the right side of the vehicle center line, and the first joint and the second joint may be arranged on the other side of the vehicle center line, either on the left or the right.

[0026] The electrical equipment may include a central battery that overlaps the vehicle center line in a plan view of the vehicle, a left battery arranged to the left of the central battery in the left-right direction of the vehicle, and a right battery arranged to the right of the central battery in the left-right direction of the vehicle. The vehicle may include a central connector that connects the central battery and the high-voltage electrical wiring. The water pipe may be arranged on either the left or the right side of the central battery, and the central connector may be arranged on the other side of the central battery, either on the left or the right.

Advantages of the Invention

[0027] According to the present invention, the work burden of maintenance or repair of the water pipe of the vehicle can be reduced.

Because the above portion of the water pipe 43 and the joint 11A and the high-voltage electrical wiring 33 are separated by a first predetermined distance or more, when the water pipe 43 is removed from the joint 11A for maintenance or repair of the water pipe 43, water is less likely to come into contact with the high-voltage electrical wiring 33 from the connection port (not shown) of the joint 11A and the water pipe 43. Because water is less likely to come into contact with the high-voltage electrical wiring 33, the workload of mechanics and users with maintenance skills is reduced when performing maintenance or repair of the water pipe 43. Similarly, in a cross-section passing through the joint 11B of the front motor 11 and perpendicular to the vehicle centerline CL, the portion of the water pipe 45 connected to the joint 11B and the joint 11B and the high-voltage electrical wiring 33 are separated from each other by a first predetermined distance or more. In a cross-section passing through joint 12A of the rear motor 12 and perpendicular to the vehicle centerline CL, the portion of the water pipe 44 connected to joint 12A and joint 12A and high-voltage electrical wiring 33 are separated from each other by a first predetermined distance or more. In a cross-section passing through joint 12B of the rear motor 12 and perpendicular to the vehicle centerline CL, the portion of the water pipe 46 connected to joint 12B and joint 12B and high-voltage electrical wiring 33 are separated from each other by a first predetermined distance or more. When the water pipe 45 is removed from joint 11B, when the water pipe 44 is removed from joint 12A, and when the water pipe 46 is removed from joint 12B, water is less likely to come into contact with the high-voltage electrical wiring 33. Therefore, the workload of mechanics and users with maintenance skills is reduced when performing maintenance or repairs on the water pipes 44, 45, and 46.

[0064] As long as the above effect is achieved, the first predetermined distance can be changed as appropriate, but in this embodiment it is set to 150 mm. Since the joints 11A, 11B, 12A, and 12B and the high-voltage electrical wiring 33 are far enough apart, water is less likely to come into contact with the high-voltage electrical wiring 33.

[0065] Joints 11A, 11B, 12A, and 12B and the high-voltage electrical wiring 33 are separated in the left-right direction. Even if water spills when water pipes 43, 45, 44, and 46 are removed from joints 11A, 11B, 12A, and 12B, the water will fall downwards. According to this embodiment, since joints 11A, 11B, 12A, and 12B and the high-voltage electrical wiring 33 are separated in the left-right direction, it is possible to more reliably prevent water from getting on the high-voltage electrical wiring 33.

[0066] The joints 11A, 11B, 12A, and 12B and the high-voltage electrical wiring 33 are separated from each other by a second predetermined distance or more in the left-right direction. The second predetermined distance can be changed as appropriate as long as the above effect is obtained, but in this embodiment it is set to 100 mm. Since the joints 11A, 11B, 12A, and 12B and the high-voltage electrical wiring 33 are sufficiently far apart, water is less likely to come into contact with the high-voltage electrical wiring 33.

[0067] The joints 11A, 11B, 12A, and 12B and the high-voltage electrical wiring 33 are separated from each other by a second predetermined distance or more in the left-right direction, and by a third predetermined distance or more in the up-down direction. The third predetermined distance can be changed as appropriate as long as the above effect is obtained, but in this embodiment it is set to 100 mm. Since the joints 11A, 11B, 12A, and 12B and the high-voltage electrical wiring 33 are sufficiently far apart, water is less likely to come into contact with the high-voltage electrical wiring 33.

[0068] Joints 11A and 12A are positioned below high-voltage electrical wiring 31, 32, 33, 34, and 35. In a vehicle cross-section relating to joint 11A, joint 11A is positioned below high-voltage electrical wiring 33, 34, and 35. Similarly, in a vehicle cross-section relating to joint 12A, joint 12A is positioned below high-voltage electrical wiring 33, 34, and 35. Even if water spills when water pipe 43 is removed from joint 11A or water pipe 44 is removed from joint 12A, the high-voltage electrical wiring 31, 32, 33, 34, and 35 are positioned higher than joints 11A and 12A, making it unlikely that water will come into contact with them.

[0069] As shown in Figure 3, the water piping group 40 has a first piping portion 44a extending in the front-rear direction. The high-voltage electrical wiring group 30 has a first wiring portion 33a extending in the front-rear direction. In the left-right direction, a central battery 22C, which is one of the vehicle components, is positioned between the first piping portion 44a and the first wiring portion 33a. The central battery 22C is positioned to the left of the first piping portion 44a and to the right of the first wiring portion 33a. According to this embodiment, even if water leaks from the first piping portion 44a, the central battery 22C is positioned between the first piping portion 44a and the first wiring portion 33a, so the water is less likely to come into contact with the first wiring portion 33a.

[0070] The above describes one embodiment of the vehicle, but this embodiment is merely one example. Many other embodiments are possible.

[0071] Electrical equipment cooled by the coolant is not limited to the control unit 55 or the drive motor. Vehicle components are not limited to the battery.

[0072] The joints 11A and 11B of the front motor 11, and the joints 12A and 12B of the rear motor 12 may be positioned to the left of the vehicle centerline CL, while a portion of the high-voltage electrical wiring 31, a portion of the high-voltage electrical wiring 32, all of the high-voltage electrical wiring 33, a portion of the high-voltage electrical wiring 34, and a portion of the high-voltage electrical wiring 35 may be positioned to the right of the vehicle centerline CL.

[0073] The water pipe 44 may be located to the left of the central battery 21C, and the central connector 25 may be located to the right of the central battery 21C. [Explanation of symbols]
