[0001] The utility model belongs to the technical field of air valve control, in particular to a seat air valve control device. Background Art

[0002] The prior art patent publication number is: CN218063501U, which discloses that the utility model provides a car, a massage seat and a multi-air path control device, including a shell, a controller, and also includes: an air valve assembly; wherein the air valve assembly includes a plurality of conjoined electromagnetic air valves installed in parallel on the shell, the conjoined electromagnetic air valve includes an air intake conjoined electromagnetic air valve for connecting an air pump and at least two air outlet conjoined electromagnetic air valves for inflation, each of the air intake conjoined electromagnetic air valve and the air outlet conjoined electromagnetic air valve includes an air inlet and an air outlet, and the air intake conjoined electromagnetic air valve and the air outlet conjoined electromagnetic air valve are suitable for controlling the opening and closing of their air outlets through a controller; an air path channel is integrated on the shell, and the air path channel includes an air pump air intake channel, an air valve air intake channel and an air valve air outlet channel, and the controller is electrically connected to the conjoined electromagnetic valve group to control the flow direction of the gas. Through this solution, the overall structural compactness of the air valve is improved, and it is easy to manage and control:

[0003] With the development of the automobile industry, people have higher and higher requirements for healthy life and seat comfort. Therefore, more functions need to be integrated into the seats. The core control components of the comfort function are mainly air valves. Air tightness is a key indicator of the air valve. As long as there is enough force acting on the rubber pad, it will be sealed. However, the greater the force acting on the rubber pad, the greater the force to open the air vent of the air valve. The air valve design hopes that this force will be smaller, so there is a contradiction between the air valve opening force and the rubber pad sealing.

[0004] A seat air valve control device is now proposed to solve the above problems. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a seat air valve control device, which solves the problems in the prior art.

[0006] In order to achieve a good seal, the sealing force must be evenly distributed to the sealing surface. If it is uneven, greater force will be required to seal it. Due to manufacturing errors and assembly errors, the rubber pad plane and the sealing plane will definitely not be parallel.

[0007] To achieve the above object, the present utility model provides the following technical solution: A seat air valve control device, comprising a housing and a circuit board. The housing includes an upper cover, a middle shell, and a bottom shell. The upper cover, the middle shell, the circuit board, and the bottom shell are connected in sequence from top to bottom.

The lumbar support air valve controls the opening and closing of the air valve air inlet and the air valve air outlet. The gas flows through the main air inlet, the air valve air inlet, and the air supply port into the air bag, forming a lumbar support inflation air path.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0038] As Figures 1-11As shown in the figure, in Embodiment 1, the present utility model provides: a seat air valve control device, including a housing and a circuit board 3.

The upper cover 1, the middle shell 2, the circuit board 3, and the bottom shell 4 are connected in sequence from top to bottom. The middle shell 2 is ultrasonically bonded to the upper cover 1 to form a gas flow cavity 21. A massage air valve cavity 24, a lumbar support air valve cavity 25, a lumbar support air bag interface 30, a massage air bag interface 29, and a main air inlet 26 are provided on the middle shell 2. A massage air valve 5 is provided in the massage air valve cavity 24, and a lumbar support air valve 6 is provided in the lumbar support air valve cavity 25. Conductive copper pins 7 are provided on the massage air valve 5 and the lumbar support air valve 6, electrically connecting to the circuit board 6. Gas enters the main air inlet 26, passes through the massage air valve cavity 24 and the lumbar support air valve cavity 25, and enters the air bags connected to the lumbar support air bag interface 30 and the massage air bag interface 29 through the lumbar support air bag interface 30 and the massage air bag interface 29, forming a lumbar support inflation air path 110 and a massage inflation air path 120. The gas in the air bags is deflated through the massage air valve cavity 24 and the lumbar support air valve cavity 25, forming a lumbar support deflation air path 130 and a massage deflation air path 140.

[0039] In this embodiment, preferably, an air valve air inlet 241, an air valve air outlet 242, and an air supply port 243 are provided on the massage air valve cavity 24. The position of the air supply port 243 is perpendicular to the positions of the air valve air inlet 241 and the air valve air outlet 242 due to the gas inflow direction or outflow direction. For example, if the air valve air inlet 241 opens in the X-axis direction of the massage air valve cavity 24, then the position of the air supply port 243 opens in the Z-axis direction of the massage air valve cavity 24. The air supply port 243 is connected to the massage air bag interface 29. The massage air valve 5 controls the opening and closing of the air valve air inlet 241 and the air valve air outlet 242.

The rocker arm 51 becomes a seesaw within the extension and contraction range of the shape memory wire 54, and the support column 27 in the middle of the rocker arm 51 is used as the support point to swing horizontally within the massage air valve cavity 24; the reset elastic member 53 here can be a spring or a torsion spring or other elastic members that perform the above functions.

The air supply port 253 is vertically arranged with respect to the gas inflow or outflow direction of the air valve air inlet 251 and the air valve air outlet 252. For example, if the air valve air inlet 251 opens in the X-axis direction of the massage air valve cavity 25, then the position of the air supply port 253 opens in the Z-axis direction of the massage air valve cavity 25; the air supply port 253 is connected to the lumbar support air bag interface 30; the lumbar support air valve 6 controls the opening and closing of the air valve air inlet 251 and the air valve air outlet 252, and the gas flows through the main air inlet 26, the air valve air inlet 251, and the air supply port 253 into the air bag to form a lumbar support inflation air path 110.

The single rocker arm 61 opens or blocks the air valve air inlet 251 or the air valve exhaust port 252 within the extension and contraction range of the shape memory wire 64, and uses the support column 27 of the single rocker arm 61 as a support point to swing horizontally within the massage air valve cavity 25; the reset elastic member 53 here can be a spring or a torsion spring or other elastic members that play the above functions.

[0044] In this embodiment, preferably, the single rocker arm 61 includes a groove 611, a U-shaped card slot 612, a hole slot 613, and a rocker arm clip 614.
