[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The present application embodiment discloses an electric vehicle controller that is easy to dissipate heat, such as Figure 1 As shown, it includes an aluminum base 1, a PCBA board 4, a MOS tube 2 and a spring 3. The PCBA board 4, the MOS tube 2 and the spring 3 are all installed on the aluminum base 1. The PCBA board 4 is used for installing electronic components. The MOS tube 2 is connected to the PCBA board 4 through pins.

[0031] like Figure 1 and 2 As shown, the aluminum base 1 is provided with a first limiting groove 12, and the first limiting groove 12 is for one side of the PCBA board 4 to be embedded. The aluminum base 1 is provided with a second limiting groove 13, and the side of the PCBA board 4 away from the bottom of the first limiting groove 12 abuts against the bottom of the second limiting groove 13. When the aluminum base 1 needs to be installed, the aluminum base 1 is moved so that one side of the aluminum base 1 is embedded in the first limiting groove 12, and the other side of the aluminum base 1 abuts against the bottom of the second limiting groove 13. The first limiting groove 12 can limit the PCBA board 4, and the bottom of the second limiting groove 13 can support the PCBA board 4, so that the PCBA board 4 is easily installed on the aluminum base 1. An auxiliary cavity 41 is formed between the PCBA board 4 and the aluminum base 1. When the electronic components on the PCBA board 4 are working, the electronic components on the PCBA board 4 will release heat, and the released heat can be transferred to the PCBA board 4. The auxiliary cavity 41 can facilitate the heat dissipation of the PCBA board 4, reduce the possibility of damage to the electronic components on the PCBA board 4, and facilitate the normal operation of the electronic components on the PCBA board 4.

When installing the connecting part 33 and the vehicle body, move the electric vehicle controller to move the connecting part 33 to a suitable installation position, then screw in the connecting bolt 332 so that the connecting bolt 332 passes through the connecting hole 3311 and is threadedly connected to the vehicle body, and the connecting bolt 332 is rotated until it abuts against the hole opening of the connecting hole 3311. The connecting bolt 332 can limit the connecting plate 331 to fix the connecting plate 331 and the vehicle body, thereby fixing the electric vehicle controller and the vehicle body and realizing the installation of the electric vehicle controller.

[0034] The implementation principle of an electric vehicle controller that facilitates heat dissipation in the embodiment of the present application is as follows:

[0035] The operator embeds one side of the PCBA board 4 into the first limiting groove 12, and the other side abuts against the bottom of the second limiting groove 13, then connects the MOS tube 2 and the PCBA board 4 through the pin, and then installs the spring piece 3, moves the positioning part 32 to make the positioning part 32 embedded in the positioning groove 11, and the positioning groove 11 can limit the positioning part 32, thereby realizing the installation of the spring piece 3; at this time, the abutting part 31 abuts against the MOS tube 2, and the heat sink 321 fits with the upper surface of the side of the MOS tube 2, so that the MOS tube 2 is firmly installed while improving the heat dissipation effect of the upper surface of the MOS tube 2; then the connecting plate 331 is installed on the vehicle body through the connecting bolts 332, thereby realizing the installation of the electric vehicle controller and the vehicle body.
