The outer surface of the shell has screw holes for fixing a wiring harness, and a wiring harness is inserted into the screw holes. The upper surface of the top cover has mounting holes with threaded connections to a vent valve. Multiple first bolts are threaded onto the upper surface of the top cover. A sealing strip is provided between the shell and the top cover on opposite sides. This protective shell for an electric vehicle controller improves the sealing performance of the device through the wiring harness sealing ring and sealing strip. The reinforcing ribs and heat dissipation strip enhance the aesthetics of the device, improve its strength, and increase the air expulsion area of ​​the shell, thus improving heat dissipation and ensuring normal vehicle operation in adverse environments and hot summers.

[0004] However, in this existing technology, the controller housing and the top cover are connected by mounting holes and bolts, which is cumbersome and difficult to disassemble, making it inconvenient to quickly install and remove the top cover and affecting the efficiency of the top cover installation and removal.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0024] like Figures 1 to 4 As shown, the present invention provides a controller cover that is easy to install, comprising: a housing 1; a cover 2 disposed on the housing 1; mounting grooves 101 formed around the housing 1; a sealing member 5 fixedly installed on the housing 1; and a plug-in assembly 3 that facilitates the installation and removal of the cover 2.

[0025] The plug assembly 3 includes: a pin 301 rotatably mounted on the upper cover 2 around the perimeter; additionally, the pin 301 is rotatably mounted on the upper cover 2 via a bearing; a positioning pin 302 fixedly mounted on the pin 301; and a guide groove 303 formed on the housing 1, in which the positioning pin 302 is inserted; the guide groove 303 is L-shaped and formed on the side wall of the housing 1, and the guide groove 303 communicates with the mounting groove 101.

[0026] When installing the car controller cover 2, the cover 2 is inserted into the corresponding mounting slot 101 through the four pins 301. At this time, the positioning pin 302 on the pin 301 moves to the lower end of the corresponding guide groove 303, and the cover 2 is pressed into place towards the housing 1, so that the sealing element 5 on the housing 1 fits tightly with the top wall of the cover 2. Then, by rotating the pin 301, after rotating the pin 301 to 90 degrees, the pin 301 locks the cover 2, realizing the quick installation of the cover 2. Moreover, by installing the cover 2 in this way, the existing screw fixing is avoided, which leaves small gaps and holes at the connection point between the screw and the housing, causing internal electrical components to get damp and easily cause malfunctions.

[0027] As a further extension of this utility model, in order to ensure the stability of the top cover 2 after installation; and a limiting component 4 for limiting the rotation of two adjacent pins 301.

[0028] The limiting component 4 includes: a limiting hole 401 formed in the pin 301; a limiting rod 402 movably mounted on the upper cover 2; a push block 403 that pushes the limiting rod 402 to move, and the bottom of the push block 403 is slidably mounted on the upper cover 2; a threaded rod 404 rotatably mounted on the push block 403; a retaining ring 405 fixedly mounted on the limiting rod 402; and a spring 406 fitted on the limiting rod 402, with one end of the spring 406 fixedly connected to the retaining ring 405 and the other end of the spring 406 fixedly mounted on the upper cover 2. It should be noted that a positioning sleeve is fixedly mounted on the upper cover 2, the limiting rod 402 is movably installed through the positioning sleeve, and one end of the spring 406 is fixedly connected to the surface of the positioning sleeve mounted on the upper cover 2.

[0029] After the plug-in components 3 around the top cover 2 are installed in the corresponding mounting slots 101, the limiting holes 401 on the pins 301 are rotated to correspond with the limiting rods 402. Then, by rotating the threaded rods 404, the threaded rods 404 push the push block 403 to move to the center of the top cover 2. At this time, the trapezoidal push block 403 squeezes and pushes the inclined surface of one end of the two symmetrical limiting rods 402, so that the other end of the limiting rods 402 is inserted into the corresponding limiting holes 401, restricting the rotation of the pins 301. This method improves the stability of the pins 301 after installation, and only two threaded rods 404 need to be rotated to limit the four pins 301, further improving the disassembly speed of the top cover 2.

[0030] It should be noted that the threaded rod 404 has a threaded sleeve threaded onto its surface, and the bottom of the threaded sleeve is fixedly mounted on the surface of the upper cover 2. When the threaded rod 404 is screwed in and out of the threaded sleeve, it can push the push block 403, which is rotatably mounted at one end of the threaded rod 404, to move.

[0031] It should be noted that the push block 403 is trapezoidal, and one end of the limiting rod 402 is designed as an inclined surface that cooperates with the push block 403. When the push block 403 presses against the inclined surface at one end of the two symmetrical limiting rods 402, it facilitates the opposite movement of the two symmetrical limiting rods 402, reducing interference between them.

[0032] It should be added that a bearing is provided at one end of the threaded rod 404, and the inner ring of the bearing is fixedly connected to the surface of the threaded rod 404, while the outer ring of the bearing is fixedly connected to the interior of the push block 403. The bearing arrangement allows the threaded rod 404 to rotate freely on the push block 403, thereby enabling the push block 403 to slide on the surface of the upper cover 2.

[0033] Working principle: During the installation of the car controller cover, the upper cover 2 is inserted into the corresponding mounting slot 101 through the four pins 301. At this time, the positioning pin 302 on the pin 301 moves to the lower end of the corresponding guide groove 303, and at the same time, the upper cover 2 is pressed into place towards the housing 1, so that the sealing element 5 on the housing 1 is tightly fitted with the top wall of the upper cover 2. Then, by rotating the pin 301, after the pin 301 is rotated to 90 degrees, the pin 301 locks the upper cover 2. At the same time, the limiting hole 401 on the pin 301 rotates to correspond with the limiting rod 402. Then, by rotating the threaded rod 404, the threaded rod 404 pushes the push block 403 to move to the middle of the upper cover 2. At this time, the trapezoidal push block 403 squeezes and pushes the inclined surface of one end of the two symmetrical limiting rods 402, so that the other end of the limiting rod 402 is inserted into the corresponding limiting hole 401, thereby restricting the rotation of the pin 301.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
