[0009] Preferably, the second connecting plate is trapezoidal, and a second bolt hole is provided on the second connecting plate, and a heat dissipation channel is provided in the center of the second connecting plate.

[0010] Preferably, the end of the second connecting plate away from the first connecting plate is mounted on the lifting lug of the motor.

[0011] Preferably, the second connecting plate is fixedly connected to the controller by bolts passing through the second bolt holes.

[0012] Preferably, the first connecting plate and the second connecting plate are provided with a first shock absorber at the connection point with the motor.

[0014] Beneficial effects:

[0015] 1. This utility model provides a mounting fixture for a vehicle axle motor controller. The controller is fixed above the motor by a first connecting plate and a second connecting plate that are perpendicular to each other. This ensures the stability of the controller installation while reducing the installation space and shortening the length of the cables required for connection.

[0016] 2. In this utility model, the bottom of the first connecting plate is clamped onto the motor via a semi-circular ring, and the end of the second connecting plate away from the first connecting plate is installed on the motor's lifting lug, thereby achieving stable support for the controller.

[0017] 3. The vibration between the controller and the motor is reduced by the first and second shock absorbers to prevent the bolts from loosening.

[0018] 4. The heat dissipation channel allows the controller to form an airflow guiding cavity with the help of the motor housing, thereby achieving auxiliary heat dissipation. Attached Figure Description

[0024] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0025] Example 1:

[0026] Provided such as Figure 1 The installation fixture for a vehicle axle motor controller shown includes: a first connecting plate 1 and a second connecting plate 2. One end of the first connecting plate 1 is connected to one end of the second connecting plate 2. The first connecting plate 1 and the second connecting plate 2 are perpendicular to each other. The first connecting plate 1 is used to support the second connecting plate 2 on the motor 3. The second connecting plate 2 is used to support and fix the controller 4.

[0027] The first connecting plate 1 and the second connecting plate 2 are integrally formed. The material of the first connecting plate 1 and the second connecting plate 2 can be metal, and more preferably aluminum alloy, with an anodized film on the surface and a thickness of 5mm.

[0028] The bottom end of the first connecting plate 1 is semi-circular, and a first bolt hole 11 is provided on the first connecting plate 1. The first connecting plate 1 is fixed to the motor 3 by bolts passing through the first bolt hole 11. The inner diameter of the first connecting plate 1 matches the outer diameter of the motor 3. By having the bottom end of the semi-circular first connecting plate 1 clamp onto the outer diameter of the motor 3, the connection and fixation are achieved using the bolts at the connection between the motor 3 and the axle. No additional connection position needs to be designed for the motor 3.

[0029] The second connecting plate 2 is trapezoidal, with a second bolt hole 21 and a heat dissipation channel 22 at its center. The second connecting plate 2 is fixedly connected to the controller 4 via bolts passing through the second bolt hole 21. The end of the second connecting plate 2 furthest from the first connecting plate 1 is mounted on the lifting lug of the motor 3. The heat dissipation channel 22 at the center of the second connecting plate 2 allows the controller 4 to utilize the motor 3 housing to form an airflow guiding cavity, achieving auxiliary heat dissipation. The end of the second connecting plate 2 furthest from the first connecting plate 1 is mounted on the lifting lug 31 of the motor 3, providing stable support for the controller 4.

[0030] A first shock absorber is provided at the connection between the first connecting plate 1 and the second connecting plate 2 and the motor 3. The first shock absorber may be a rubber bushing, which is fitted on the surface of the first connecting plate 1 and the second connecting plate 2, or glued to the surface of the first connecting plate 1 and the second connecting plate 2, to reduce high-frequency vibration between the first connecting plate 1 and the second connecting plate 2 and the motor 3.

[0031] A second damping component is provided at the connection between the second connecting plate 2 and the controller 4. The second damping component can be a silicone-metal laminate, which is a layered structural material that combines silicone and metal materials. The silicone layer has good flexibility, insulation, temperature resistance and chemical stability, while the metal layer has good electrical conductivity, thermal conductivity and mechanical strength. The silicone-metal laminate can suppress the low-frequency resonance of the controller 4 mounted on the second connecting plate 2.

[0032] In this embodiment, as Figures 2-3 The diagram shown is an assembly diagram of the axle motor 3 and controller 4 installed using this device.

[0033] The bottom end of the semi-circular first connecting plate 1 is clamped onto the outer diameter of the motor 3. The first connecting plate 1 is fixed to the motor 3 by using bolts at the connection point between the motor 3 and the axle, passing through the first bolt hole 11. No additional connection position is required for the motor 3. The end of the second connecting plate 2 furthest from the first connecting plate 1 is mounted on the lifting lug 31 of the motor 3. The top of the lifting lug 31 supports the second connecting plate 2, maintaining overall stability. The second connecting plate 2 is parallel to the axis of the motor 3, while the first connecting plate 1 and the second connecting plate 2 are perpendicular. The controller 4 is fixed to the second connecting plate 2 by bolts passing through the second bolt hole 21. Compared to installing the controller 4 separately, this installation method reduces installation space by 35%, cable loss by 15%, and improves the heat dissipation efficiency of the controller 4 by 30%. In vibration tests, the loosening rate of the connectors is close to zero, demonstrating good shock absorption performance and preventing loosening of bolts and other connectors. It has strong compatibility, is simple and quick to use, and can be used for the installation of controllers 4 on multiple models of axle motors 3.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
