[0029] Example 1: Reference Figure 1-Figure 4 A motor controller is used in the field of controllers, including: a controller 2, which is the core control component of an electric vehicle and is responsible for receiving and sending instructions to control the driving state of the electric vehicle. A bottom plate 1 is fixedly provided at the bottom of the controller 2, and the bottom plate 1 is used to support the controller 2 and provide an installation basis. Two groups of first bolts 4 are penetrated through the top of the bottom plate 1, and the bottom ends of the first bolts 4 are threadedly connected to the electric vehicle frame, so that the controller 2 can be fixed on the electric vehicle frame. The controller 2 adopts the controller body in the patent document CN220797302U.

[0030] Two groups of clamping mechanisms are provided on the base plate 1, which are used to quickly fix the base plate 1 on the two groups of first bolts 4. Each group of clamping mechanisms includes two groups of positioning columns 10 that pass through the top of the base plate 1. The positioning columns 10 are rotatably sleeved on the first bolts 4. When installation is required, the positioning columns 10 are placed flush with the top of the base plate 1, and then the base plate 1 is placed on the electric vehicle frame so that the first bolts 4 are threaded on the frame. Then, two groups of fixing plates 12 are fixed on the top of the base plate 1, and a pin column 13 is slidably provided on one side of the fixing plate 12. A socket 11 used in conjunction with the pin column 13 is opened on the outer side of the positioning column 10. The pin column 13 is inserted into the socket 11, so that the positioning column 10 is fixed to the base plate 1, thereby achieving the fixation of the base plate 1 and the electric vehicle frame.

[0031] In order to limit the pin 13, two groups of limiting members are provided on the base plate 1, and the limiting members include two nut seats 16 that are fixed through the top of the base plate 1, and a second bolt 17 is threaded through the top of the nut seat 16. A groove 18 is provided on one side of the nut seat 16, and one end of the two pins 13 is fixed with the same connecting rod 14, and the connecting rod 14 is located in the groove 18. By rotating the second bolt 17 so that the annular groove 19 provided on the outer wall corresponds to the connecting rod 14, the connecting rod 14 can move, thereby releasing the limitation of the pin 13. When fixing is required, the second bolt 17 is rotated in the opposite direction to stagger the annular groove 19 and the connecting rod 14. The connecting rod 14 is reset under the elastic force of the spring 15, driving the pin 13 to be inserted into the socket 11, thereby realizing the fixation of the base plate 1 and the electric frame.

[0032] A plurality of groups of wires 5 are provided on the controller 2 for connecting the controller 2 with other electrical components inside the electric vehicle. One end of the wire 5 is connected with the electrical components inside the controller 2, and the other end is fixedly provided with a plug 7 plugged into the internal connector of the electric vehicle. In order to facilitate the fixing of the plug 7, a limiting mechanism is provided on one side of the base plate 1. The limiting mechanism includes a connecting piece 6 fixedly provided on one side of the base plate 1, and the length of the connecting piece 6 is smaller than the wire 5, which can prevent the wire 5 from being pulled. A first card plate 8 is fixedly provided on the other end of the connecting piece 6, and a second card plate 9 is clamped on the top of the first card plate 8. Positioning grooves 23 corresponding to the plug 7 are provided on the sides of the first card plate 8 and the second card plate 9 close to each other. The plug 7 is placed in the positioning groove 23, and then the second card plate 9 is covered to achieve simultaneous fixing of multiple plugs 7. In order to facilitate disassembly, two groups of card strips 21 are fixedly provided at the bottom of the second card plate 9, and a card hole 22 corresponding to the card strip 21 is provided on the top of the first card plate 8. After the card strip 21 is inserted into the card hole 22, the bottom end conflicts with the first card plate 8, thereby achieving the fixing of the second card plate 9.
