The vehicle controller is a component that easily generates heat, which will cause an imbalance in the air pressure inside and outside the vehicle controller. Therefore, a breather valve is generally installed on the vehicle controller.

[0003] For example, a high-protection breathable valve balancing assembly (CN212004452U) disclosed in a Chinese patent includes a valve housing, a sealing mechanism and a breathable membrane, the valve housing includes a valve cover and a valve body, the valve cover is clamped on the valve body having a through hole, the valve cover is a plum blossom-shaped claw snap-on valve cover, and the valve body is provided with a buckle groove used in conjunction with the valve cover; the sealing mechanism includes a sealing ring and a limiting groove, the sealing ring and the limiting groove have the same volume, the limiting groove is arranged on the valve body, and the sealing ring is arranged at the opening of the limiting groove; the breathable membrane is arranged in the through hole and connected to the valve body, and is arranged adjacent to the valve cover.

[0004] The shortcomings of the above-mentioned prior art are: the valve cover in the air valve is a plum blossom-shaped claw snap-on valve cover. Due to the frequent vibration of the vehicle controller, the snap-on structure and the shell are easy to loosen, which eventually causes the air valve to fall off and lose its protective function; the overall axial dimension of the air valve is large, resulting in more protrusions from the shell, which is not convenient for installation and is easy to be collided. Summary of the invention

[0010] Preferably, the two arc-shaped slide grooves are symmetrical around the center of the air hole.

[0011] Preferably, the two arc-shaped bosses are symmetrical around the center of the air hole.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 6 As shown, a breathable valve fixing structure is provided, with an air hole 2 on the shell 1, and a first countersunk hole 201 is provided at the outer end of the air hole 2, and a circular breathable membrane 5 is placed in the first countersunk hole 201. Two arc-shaped slide grooves 3 and two arc-shaped bosses 4 arranged around the air hole 2 are provided on the outer surface of the shell 1, and the arc-shaped bosses 4 are located outside the arc-shaped slide grooves 3. The two arc-shaped slide grooves 3 and the two arc-shaped bosses 4 are symmetrically arranged around the center of the air hole 2. A limiting groove 401 is provided on the side of the arc-shaped boss 4 close to the air hole 2, and a limiting hole is provided on the side of at least one arc-shaped boss 4 away from the air hole 2, and a positioning pin 7 is installed in the limiting hole. The positioning pin 7 is against one side of the breathable valve cover 6.

[0023] Recombination Figure 6 As shown, the air-permeable valve cover 6 covers the outside of the air-permeable membrane 5. Two slide posts 603 are fixed to one side of the air-permeable valve cover 6 that is in contact with the housing 1, and the two slide posts 603 are respectively installed in the two arc-shaped slide grooves 3. The arc-shaped slide grooves 3 limit the air-permeable valve cover 6 and allow the air-permeable valve cover 6 to rotate around the arc-shaped slide grooves 3. The air-permeable valve cover 6 has protrusions at both ends, and by rotating around the arc-shaped slide grooves 3, the protrusions of the air-permeable valve cover 6 enter the limiting grooves 401 of the arc-shaped boss 4. The two sides of the protrusions of the air-permeable valve cover 6 are limited between the inner ends of the limiting grooves 401 and the positioning pins 7.

[0024] The side of the air-permeable valve cover 6 that is attached to the housing 1 is provided with a second countersunk hole 601, which is opposite to the air-permeable membrane 5, and the diameter of the second countersunk hole 601 is smaller than the diameter of the air-permeable membrane 5. The side of the air-permeable valve cover 6 that is attached to the housing 1 is also provided with four ventilation grooves 602 that are connected to the second countersunk hole 601. After the air-permeable valve cover 6 is attached to the surface of the housing 1, the external control reaches the second countersunk hole 601 through the ventilation grooves 602, then passes through the air-permeable membrane 5, and then enters the air hole 2.

[0025] Working principle:

[0026] When in use, firstly, the adhesive surface of the breathable membrane 5 is attached to the first countersunk hole 201 outside the air hole 2;

[0027] Then press the breathable valve cover 6 onto the breathable membrane 5, and the slide post 603 of the breathable valve cover 6 is correspondingly inserted into the arc-shaped slide groove 3; rotate the breathable valve cover clockwise to more than 60 degrees, and the breathable valve cover 6 protrudes into the limiting groove 401 of the arc-shaped boss 4;

[0028] Finally, insert the positioning pin 7 into the limiting hole on the arc-shaped boss 4 to complete the installation;

[0029] The present invention is easy to install and disassemble, and is firmly fixed, thus avoiding the problem of the air valve cover falling off; the air valve fixing structure is simple, with fewer installation parts and a small overall axial size, and simple plastic parts can be used without the need for fine processes such as thread processing, and the product cost is low.
