[0021] Please see Figure 1-3 This utility model provides a technical solution for an electric vehicle controller: it includes a housing 1, a base 2 installed at the bottom of the housing 1, connecting plates 3 fixedly installed on both sides of the base 2, a control circuit board 5 disposed inside the housing 1, a shielding layer 6 disposed inside the housing 1, the shielding layer 6 wrapping around the outside of the control circuit board 5, a heat-conducting plate 7 fixedly installed inside the housing 1, the heat-conducting plate 7 passing through the shielding layer 6 and fitting against the control circuit board 5, heat sinks 8 fixedly installed on the housing 1 and the base 2, the heat sinks 8 being connected to the heat-conducting plate 7, a wire harness hole 4 disposed on one side of the housing 1, a wire harness 9 disposed in the wire harness hole 4, and the wire harness 9 passing through the wire harness hole 4 and connecting to the control circuit board 5.

[0022] Furthermore, a limiting platform 10 is fixedly provided on the upper surface of the base 2, the bottom of the housing 1 is snapped onto the outside of the limiting platform 10, and the bottom of the base 2 is fixedly connected to the housing 1 by screws.

[0023] Furthermore, the heat-conducting plate 7 is a copper heat-conducting plate 7, which includes an upper heat-conducting plate 17 and a lower heat-conducting plate 18. The top end of the upper heat-conducting plate 17 is located on the housing 1, and the housing 1 is provided with mounting holes for mounting the upper heat-conducting plate 17.

[0024] Furthermore, a groove 11 is provided on the top of the housing 1, and a heat sink 12 is fixedly installed in the groove 11. The heat sink 8 is evenly installed on the heat sink 12, and the bottom of the heat sink 12 is in contact with the upper heat conduction plate 17.

[0025] In this embodiment, the heat sink 12 can effectively dissipate the heat generated by the control circuit board 5 through the heat conduction plate 7 and the heat sink 8, thereby improving the heat dissipation efficiency of the electric vehicle controller. The bottom of the heat sink 12 is in close contact with the upper heat conduction plate 17, ensuring rapid heat transfer and further enhancing the heat dissipation effect.

[0026] Furthermore, the bottom of the lower heat-conducting plate 18 is inserted into the base 2, and the lower heat-conducting plate 18 is connected to the heat sink 8 through the heat dissipation plate 12 below it.

[0027] In this embodiment, the lower heat-conducting plate 18 can effectively further disperse the heat transferred from the upper heat-conducting plate 17 onto the base 2, thereby increasing the heat dissipation area.

[0028] Furthermore, the shielding layer 6 is provided with fixing holes for mounting the upper heat-conducting plate 17 and the lower heat-conducting plate 18.

[0029] Furthermore, connecting seats 16 are fixedly provided on both sides of the shielding layer 6, and the connecting seats 16 are fixedly installed on the inner wall of the housing 1 by limiting blocks 13.

[0030] In this embodiment, the connecting plate 3 not only enhances the stability of the shielding layer 6, but also helps to firmly fix the shielding layer 6 inside the housing 1, preventing it from shaking or shifting during the operation of the electric vehicle controller. The limiting block 13, as a fixing component between the connecting plate 3 and the inner wall of the housing 1, is reasonably designed and easy to install.

[0031] Furthermore, the inner side of the connecting plate 3 is provided with a limiting slot 15 for installing the control circuit board 5, and the two ends of the control circuit board 5 are equipped with locking blocks 14.

[0032] In this embodiment, the design of the limiting slot 15 enables the control circuit board 5 to be securely installed inside the connecting plate 3, avoiding loosening or damage to the circuit board due to vibration or bumps, and facilitating the assembly and maintenance of the electric vehicle controller.

[0034] Working Principle: During use, the control circuit board 5 of the electric vehicle controller is connected to the external power supply and components such as the electric vehicle motor via the wiring harness 9. The control circuit board 5 receives and processes external signals to control the electric vehicle motor's start, operation, forward and reverse movement, speed, and stop. Simultaneously, the control circuit board 5 generates heat during operation. This heat is transferred to the heat sink 8 through the heat conduction plate 7, and the heat sink 8 dissipates the heat into the air, thus achieving heat dissipation. Furthermore, the shielding layer 6 effectively shields external electromagnetic signals, reducing interference to the control circuit board 5 and improving the controller's anti-interference capability. Moreover, a limiting platform 10 is fixedly installed on the upper surface of the base 2, and the bottom of the housing 1 is snapped onto the outside of the limiting platform 10. The bottom of the base 2 is fixedly connected to the housing 1 with screws. This connection method makes the installation and disassembly of the controller more convenient, facilitating maintenance and replacement.
