Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a clamping device for electric wheel high-voltage wiring harness and cooling water pipe. Background Technology

[0002] Electric wheel drive is a drive system that places electric motors directly within the wheel hubs of a car, a design that differs from traditional power transmission systems. Traditional cars typically use an engine to transmit power to the wheels via driveshafts and gears, while electric wheel drive places an independent electric motor inside each wheel, achieving direct drive. This structure not only simplifies the mechanical transmission components but also results in higher energy efficiency and performance.

[0003] The electric wheel module is matched with independent suspension and steering functions. The electric wheel moves up and down with the suspension and rotates around the steering kingpin when the wheel turns. Therefore, the high-voltage wiring harness and coolant pipes leading from the electric wheel have a large range of motion. Due to the limited space around the electric wheel, they need to be specially fixed. On the one hand, this restricts the movement space of the wiring harness to avoid interference with surrounding structures; on the other hand, the wiring harness needs to have a certain degree of freedom to prevent excessive bending and damage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a clamping device for high-voltage wiring harnesses and cooling water pipes of electric wheels. This device can restrict the degrees of freedom of the cable clamps and water pipe clamps in the X, Z, and Y directions, while releasing the degrees of freedom of the cable clamps and water pipe clamps in the Y, X, and Z directions. It can restrict the wheel-side wiring harness within a certain range of motion, and the wiring harness can bend naturally during the movement of the electric wheel, thus meeting the fixing requirements of the electric wheel wiring harness.

[0005] This utility model is achieved using the following technical solution:

[0006] A clamping device for a high-voltage wiring harness and cooling water pipe of an electric wheel includes a base, a rotating block on the base, a U-shaped fork on the rotating block, a swing arm on the U-shaped fork, a cable clamp and a water pipe clamp on the swing arm, the cable clamp holding the high-voltage cable at the wheel end, the water pipe clamp holding the cooling water pipe at the wheel end, the high-voltage cable at the wheel end being connected to the high-voltage cable at the vehicle end, and the cooling water pipe at the wheel end being connected to the cooling water pipe at the vehicle end.

[0007] Furthermore, the rotating block includes a double-axis block, a support block, and a fixing bolt. The double-axis block has connecting holes at both ends and is located inside the base. The support block and the fixing bolt pass through the elongated holes provided in the base and are located in the connecting holes to movably connect the double-axis block to the base. The upper end of the double-axis block has a U-shaped fork mounting hole, and the U-shaped fork is located in the U-shaped fork mounting hole.

[0008] Furthermore, the U-shaped fork includes a rotating shaft and a U-shaped fork head. The upper end of the rotating shaft is provided with the U-shaped fork head. The rotating shaft is located in the mounting hole of the U-shaped fork, and the U-shaped fork head is provided with the swing arm.

[0009] Furthermore, the swing arm has a cross-shaped structure, with a pipe clamp mounting hole at the upper end of the swing arm, where the water pipe clamp is installed, and a wire clamp mounting hole at the lower end of the swing arm, where the cable clamp is installed.

[0010] Furthermore, the left and right ends of the swing arm are provided with pins, and the pins are located in the pin holes provided in the U-shaped fork head.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] It satisfies the motion freedom requirements of the cable clamps for the high-voltage cables at the wheel end and the water pipe clamps for the cooling water pipes at the wheel end around the Z-axis, X-axis, and Y-axis, while restricting the rotational freedom of the cable clamps for the high-voltage cables at the wheel end and the water pipe clamps for the cooling water pipes at the wheel end in the X-axis, Z-axis, and around the Y-axis. It solves the problem of fixing the high-voltage cables at the wheel end and the cooling water pipes at the wheel end in the narrow space next to the electric wheel, avoids motion interference with the surrounding suspension structure, and improves the reliability of the high-voltage cables at the wheel end and the cooling water pipes at the wheel end.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0020] like Figures 1-4 As shown, an electric wheel high-voltage wiring harness and cooling water pipe clamping device includes a base 10, a rotating block 9 on the base 10, a U-shaped fork 8 on the rotating block 9, a swing arm 7 on the U-shaped fork 8, the swing arm 7 being movably connected to the U-shaped fork 8, the swing arm 7 having a cable clamp 3 and a water pipe clamp 4, the cable clamp 3 clamping the wheel-end high-voltage cable 1, the water pipe clamp 4 clamping the wheel-end cooling water pipe 2, the wheel-end high-voltage cable 1 being connected to the vehicle-end high-voltage cable 5, and the wheel-end cooling water pipe 2 being connected to the vehicle-end cooling water pipe 6.

[0021] The high-voltage cable 1 at the wheel end and the cooling water pipe 2 at the wheel end are fixed by cable clamp 3 and water pipe clamp 4, respectively. Both cable clamp 3 and water pipe clamp 4 are mounted on the swing arm 7. The swing arm 7 is connected to the U-shaped fork 13 via a pin 12 and can swing around the pin 12 (i.e., around the X-axis). The U-shaped fork 8 is mounted on the rotating block 9 via its rotating shaft 14 and can rotate around the Z-axis. The rotating block 9 is bolted to the base 10 and can simultaneously drive the U-shaped fork 8 connected to it to rotate around the X-axis. The base 10 is mounted on the independent suspension control arm of the electric wheel and provides support for the entire clamping device.

[0022] The high-voltage cable and cooling water pipe from the vehicle to this clamping device are the vehicle-end high-voltage cable 5 and the vehicle-end cooling water pipe 6. The high-voltage cable and cooling water pipe from this clamping device to the electric wheel are the wheel-end high-voltage cable 1 and the wheel-end cooling water pipe 2. When the electric wheel turns and bounces, the wheel-end cooling water pipe 2, the wheel-end high-voltage cable 1, the vehicle-end high-voltage cable 5, and the vehicle-end cooling water pipe 6 will be driven to generate oscillating motion in the XY plane and the YZ plane. This motion is converted into rotation around the Z-axis, rotation around the X-axis, and Y-axis motion by this clamping device. The clamping device of this utility model can release the motion freedom of the cable clamp 3 and the water pipe clamp 4 around the Z-axis, around the X-axis, and in the Y-axis through the above components, while restricting the motion freedom in the X-axis, Z-axis, and around the Y-axis to avoid motion interference with the surrounding suspension structure.

[0023] The rotating block 9 includes a double-shaft block 16, a support block 15, and a fixing bolt 11. The double-shaft block 16 has connecting holes at both ends. The double-shaft block 16 is located inside the base 10. The support block 15 and the fixing bolt 11 pass through the elongated holes provided in the base 10 and are located in the connecting holes, so as to movably connect the double-shaft block 16 and the base 10. The upper end of the double-shaft block 16 has a U-shaped fork mounting hole, and the U-shaped fork 8 is located in the U-shaped fork mounting hole.

[0024] The rotating block 9 is used to support the U-shaped fork 8 and realize the rotational movement of the U-shaped fork 8 around the Z-axis and the rotational movement of the rotating block 9 itself around the X-axis, thereby releasing the degrees of freedom of the cable clamp 3 and the water pipe clamp 4 to rotate around the X-axis and around the Z-axis.

[0025] The U-shaped fork 8 includes a rotating shaft 14 and a U-shaped fork head 13. The upper end of the rotating shaft 14 is provided with the U-shaped fork head 13. The rotating shaft 14 is located in the mounting hole of the U-shaped fork, and the U-shaped fork head 13 is provided with a swing arm 7.

[0027] The swing arm 7 is used to install the cable clamp 3 and the water pipe clamp 4. The pin 12 can realize the swing of the swing arm 7. Combined with the rotational movement of the U-shaped fork 8 around the X-axis, the cable clamp 3 and the water pipe clamp 4 can be released in terms of rotation around the X-axis and movement in the Y direction.

[0028] The left and right ends of the swing arm 7 are provided with pins 12, which are located in the pin holes provided in the U-shaped fork head 13.

[0029] The U-shaped fork head 13 is used to install the swing arm 7, and the rotating shaft 14 is used to release the rotational freedom of the cable clamp 3 and the water pipe clamp 4 around the Z-axis.
