Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-3 A controller circuit board fixed assembly structure shown in the figure includes a heat dissipation base 1, a protective shell 2 is fixedly installed on the top of the heat dissipation base 1, a connecting pin 7 is fixedly connected to the top of the circuit board body 3, a docking shell 8 corresponding to the connecting pin 7 is fixedly connected to the top of the protective shell 2, and a through hole matching the connecting pin 7 is opened at the bottom of the inside of the docking shell 8, so that when the protective shell 2 is installed, the connecting pin 7 passes through the protective shell 2, so that the external wiring head can be inserted into the inside of the docking shell 8 and electrically connected to the connecting pin 7, so that the circuit board body 3 can be connected to the data line, and the top of the circuit board body 3 is set There is a protective bracket 9, and a fixing screw 10 is arranged on the top of the protective bracket 9. The protective bracket 9 is fixedly connected to the circuit board body 3 by the fixing screw 10. The top of the heat dissipation base 1 is slidably clamped with the circuit board body 3. The protective bracket 9 can limit the components on the top of the circuit board body 3, and the top of the protective shell 2 is provided with a hole matching the fixing screw 10, and the bottom of the heat dissipation base 1 is provided with a screw. The heat dissipation base 1 is fixedly connected to the protective shell 2 by screws, and mounting holes are arranged at the corners of the top of the heat dissipation base 1. It can be fixed at the specified position of the electric vehicle by bolts to ensure its stability in use.

[0021] In particular, the side of the top of the circuit board body 3 is fixedly connected with the terminal 4 in a straight state, the top of the heat dissipation base 1 is fixedly connected with a mounting plate 5 parallel to the terminal 4, and the outer wall of the mounting plate 5 is symmetrically slidably clamped with an elastic clamping piece 6. Since the side of the circuit board body 3 is clamped to the bottom of the heat dissipation base 1, the elastic clamping piece 6 also squeezes and limits the height of the terminal 4, thereby ensuring the stability of the circuit board body 3 installed inside the heat dissipation base 1, and the clamping piece 6 has a certain elastic deformation ability, so that the circuit board body 3 can be installed or removed by pulling out the clamping piece 6, thereby improving the convenience of installation and disassembly of the circuit board body 3, and the clamping piece 6 locks the circuit board body 3 by squeezing the terminal 4.

[0022] Specifically, the clamping member 6 includes a horizontal plate member 61, a first extruded plate member 62 and a second extruded plate member 63, the first extruded plate member 62 and the second extruded plate member 63 are relatively fixedly connected to the side of the horizontal plate member 61, and the first extruded plate member 62 and the second extruded plate member 63 are respectively extruded and clamped on the side opposite to the mounting plate 5 and the terminal 4, as shown in FIG. Figure 2As shown, the first extruded plate 62 and the second extruded plate 63 on the clamping member 6 can extrusion-limit the mounting plate 5 and the connecting terminal 4 by extruding them.

[0023] Furthermore, a circular arc clamping portion 64 is fixedly connected to the bottom of the first extruded plate 62, and a clamping groove 65 is provided on the side of the mounting plate 5 away from the wiring terminal 4. The circular arc clamping portion 64 is slidably clamped in the inside of the clamping groove 65. The circular arc clamping portion 64 can improve the stability of the clamping member 6 clamped on the mounting plate 5 and the wiring terminal 4, and the back of the first extruded plate 62 is symmetrically provided with a limiting groove, and the inner wall of the clamping groove 65 is fixedly connected with a limiting strip matching the limiting groove. When the limiting strip is clamped in the inside of the limiting groove, the clamping member 6 can be limited again to prevent the clamping member 6 from sliding outside the mounting plate 5 and the wiring terminal 4. The bottom of the circular arc clamping portion 64 is fixedly connected to a first guide plate 66 tilted away from the mounting plate 5, and the bottom of the second extruded plate 63 is fixedly connected to a second guide plate 6 tilted away from the wiring terminal 4 7. The first guide plate 66 and the second guide plate 67 facilitate pressing the card connector 6 downward so that the card connector 6 is clamped on the outside of the mounting plate 5 and the terminal 4. The distance between the bottom of the first guide plate 66 and the bottom of the second guide plate 67 is greater than the distance between the opposite sides of the mounting plate 5 and the terminal 4. Therefore, by directly squeezing the card connector 6 downward, the card connector 6 can be directly clamped on the outside of the mounting plate 5 and the terminal 4. Since the first guide plate 66 and the second guide plate 67 are tilted in opposite directions, it is convenient to pull the first guide plate 66 and the second guide plate 67 in opposite directions to separate the card connector 6 from the mounting plate 5 and the terminal 4. A groove 68 matching the terminal 4 is provided on one side of the second extrusion plate 63. The groove 68 facilitates the arrangement of the leads on the terminal 4.
