[0003] With the development of the automobile industry, people have higher and higher requirements for healthy living 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. The power supply method of the air valve is particularly important because the air valve needs to cooperate with multiple parts. The parts have different thermal expansion and contraction rates due to different materials. If the conductive part is directly welded on the circuit board, the solder joints may crack due to the different thermal expansion and contraction rates of the materials. Therefore, the power supply of the air valve requires other more reliable methods;

[0004] An automobile, a massage seat and a seat air valve control device are now proposed to solve the above problems. Utility Model Content

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] In this embodiment, preferably, a valve air inlet 241, a 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 valve air inlet 241 and the valve air outlet 242 due to the gas inflow direction or outflow direction. For example, if the 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 valve air inlet 241 and the valve air outlet 242, and the gas flows through the main air inlet 26, the valve air inlet 241, and the air supply port 243 into the air bag, forming a massage inflation air path 120.

[0035] In this embodiment, preferably, the massage air valve 5 includes a rocker arm 51, a plug 52, a reset elastic member 53, a shape memory wire 54, and a conductive metal clip 55; the two ends of the rocker arm 51 are provided with plugs 52, and the plugs 52 are correspondingly arranged with the air valve air inlet 241 and the air valve air outlet 242; the conductive metal clip 55 clamps both ends of the shape memory wire 54 and is connected to the conductive copper needle 7; the shape memory wire 54 is wound around the rocker arm 51; the reset elastic member 53 is located on one side of the rocker arm 51; when the conductive copper needle 7 energizes the shape memory wire 54, the shape memory wire 54 extends and stretches due to the heating effect, and the reset elastic member 53 presses against the rocker arm 51, so that the plug 52 at one end of the rocker arm 51 blocks the air valve air inlet 241 or the air valve air outlet 242; when the conductive copper needle 7 cuts off the power supply to the shape memory wire 54, the shape memory wire 54 contracts, and the reset elastic member 53 presses against the rocker arm 51, so that the plug 52 at one end of the rocker arm 51 blocks the air valve air inlet 241 or the air valve air outlet 242; of course, only one of the air valve air inlet 241 and the air valve air outlet 242 can be blocked by the plug 52, rather than both being blocked. The rocker arm 51 becomes a seesaw within the extension and contraction range of the shape memory wire 54, using the support column 27 in the middle of the rocker arm 51 as the support point and swinging horizontally in 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 play 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 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.

[0039] 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.

A massage air valve is arranged in the massage air valve cavity, and a lumbar support air valve is arranged in the lumbar support air valve cavity. Conductive copper pins are arranged on the massage air valve and the lumbar support air valve and are electrically connected to the circuit board. Gas enters the main air inlet, passes through the massage air valve cavity and the lumbar support air valve cavity, and enters the air bags connected to the lumbar support air bag interface and the massage air bag interface through the lumbar support air bag interface and the massage air bag interface, forming a lumbar support inflation air path and a massage inflation air path. The gas in the air bags is exhausted through the massage air valve cavity and the lumbar support air valve cavity, forming a lumbar support deflation air path and a massage deflation air path. The conductive copper pins pass through the middle shell and are integrally formed with the middle shell and are electrically connected to the circuit board. The conductive copper pins supply power to the massage air valve and the lumbar support air valve.

2. The seat air valve control device according to claim 1, wherein: The conductive copper pin includes a copper pin, a claw spring, and a copper pin seat. The copper pin seat is arranged on the circuit board and is electrically connected to the circuit board. The claw spring is arranged in the copper pin seat. The copper pin is integrally formed with the middle shell, passes through the copper pin seat, and is connected to the claw spring.

3. The seat air valve control device according to claim 2, characterized in that: The claw spring includes a spring seat and a spring piece. The spring piece is made of a conductive material. The spring seat is movably connected to the spring piece. The spring seat is in interference fit with the copper pin seat. The copper pin passes through the spring piece, and the spring piece abuts against the copper pin seat.

4. The seat air valve control device according to claim 2, wherein: The claw spring is made of a conductive material. The claw spring includes a spring seat and a spring piece. The spring seat and the spring piece are integrally formed. The spring seat is in interference fit with the copper pin seat. The copper pin is clamped in the spring piece.

5. A massage seat, which includes an airbag, is characterized in that, It further includes the seat air valve control device according to any one of claims 1 to 4, wherein the massage air bag interface and the lumbar support air bag interface are connected to an air supply port. The massage air bag interface and the lumbar support air bag interface are connected to an air bag. The lumbar support inflation air path and the massage inflation air path provide a gas source for the air bag.

6. The massage seat according to claim 5, wherein The air bag is communicated with the air supply port to exhaust air. The seat air valve control device controls the massage air valve and the lumbar support air valve to open the air valve exhaust port, and discharges the gas in the air bag through the massage deflation air path and the lumbar support deflation air path.

7. A vehicle, characterized in that, It includes the massage seat according to any one of claims 5 to 6.
