[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1.

[0020] 4. This utility model utilizes the structure of the upper cover and the bottom shell to place the circuit board in the middle, which greatly reduces the thickness of the seat valve control device and is suitable for the thickness requirements of some seat components.
[0021] 5. This utility model provides dual services of lumbar and back massage to seat users by controlling the gas through the lumbar support inflation circuit, massage inflation circuit, lumbar support deflation circuit, and massage deflation circuit via the massage air valve and lumbar support air valve.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] like Figure 1-11As shown in Embodiment 1, this utility model provides: a seat air valve control device, including a housing and a circuit board 2. The housing includes an upper cover 1 and a lower cover 3, which are connected sequentially from top to bottom. The middle cover 3 forms a gas flow cavity by ultrasonically bonding the upper cover 1. The lower cover 3 is provided with a massage air valve cavity 35, a lumbar support air valve cavity 34, a lumbar support air bag interface 32, a massage air bag interface 31, and a main air inlet 8. A massage air valve 5 is provided in the massage air valve cavity 35, and a lumbar support air valve 6 is provided in the lumbar support air valve cavity 34. The massage air valve 5 and the lumbar support air valve 6 are provided with snap-fit mechanisms. The slot 651 has a clamping member 65 clamped in it, and the clamping member 65 is electrically connected to the circuit board 2. Gas enters the main air inlet 8, passes through the massage air valve chamber 35 and the waist support air valve chamber 34, and enters the air bag connected to the waist support air bag interface 32 and the waist support air bag interface 31 through the waist support air bag interface 32 and the waist support air bag interface 31, forming the waist support inflation air path and the massage inflation air path. The gas in the air bag is released through the massage air valve chamber 35 and the waist support air valve chamber 34, forming the waist support release air path and the massage release air path. The clamping members (55, 65) are made of metal, can conduct electricity, and can also clamp the memory metal wire 54.
[0037] In this embodiment, the massage valve cavity 35 is provided with a valve inlet, a valve outlet, and an air delivery port. The position of the air delivery port is perpendicular to the positions of the valve inlet and the valve outlet due to the gas inflow or outflow direction. For example, if the valve inlet opens in the X-axis direction of the massage valve cavity 35, then the air delivery port opens in the Z-axis direction of the massage valve cavity 35. Preferably, the position of the air delivery port is set on the same horizontal plane as the positions of the valve inlet and the valve outlet due to the gas inflow or outflow direction. For example, if the valve inlet opens in the Z-axis direction of the massage valve cavity 35, then the air delivery port opens in the Z-axis direction of the massage valve cavity 35.
[0038] The air inlet is connected to the waist support air bag interface 31; the massage air valve 5 controls the opening and closing of the air valve inlet and the air valve outlet, and the gas flows through the main air inlet 8, the air valve inlet and the air inlet into the air bag to form a massage inflation air path.
[0039] In this embodiment, the massage air valve 5 includes a rocker arm 51, a plug 52, a reset elastic element 53, a memory metal wire 54, and a clamping element 55. The rocker arm 51 has plugs 52 at both ends, corresponding to the air valve inlet and outlet. At least two sets of clamping elements 55 are needed to clamp both ends of the memory metal wire 54, electrically connected to the circuit board 2. The memory metal wire 54 is sleeved on the forward tilting part 511, with the end of the forward tilting part 511 away from the clamping element 55 tilting forward. The reset elastic element 53 is located on one side of the rocker arm 51, particularly against the side of the forward tilting part 511. When the clamping element 55 energizes the memory metal wire 54, the memory metal wire 54 extends due to the heating effect. When the rocker arm is extended, the reset elastic element 53 presses against the rocker arm 51, causing the plug 52 at one end of the rocker arm 51 to block the air valve inlet or outlet. When the clamping member 55 de-energizes the memory metal wire 54, the memory metal wire 54 retracts, and the reset elastic element 53 presses against the rocker arm 51, causing the plug 52 at one end of the rocker arm 51 to block the air valve inlet or outlet. Of course, only one of the air valve inlet and outlet can be blocked by the plug 52, not both. Within the extension and retraction range of the memory metal wire 54, the rocker arm 51 becomes a seesaw, using a fulcrum in the middle of the rocker arm 51 to make the massage air valve cavity 35 swing horizontally. The reset elastic element 53 here can be a spring, a torsion spring, or other elastic element that performs the above function.
[0040] In this embodiment, the rocker arm 51 includes a forward tilting portion 511, which is disposed at one end of the rocker arm 51 near the plug 52.
[0041] In this embodiment, the lumbar support air valve cavity 34 is provided with an air valve inlet, an air valve outlet, and an air delivery port. The air delivery port is perpendicular to the gas inflow or outflow direction of the air valve inlet and the air valve outlet. For example, if the air valve inlet opens in the X-axis direction of the massage air valve cavity 35, then the air delivery port opens in the Z-axis direction of the massage air valve cavity 35. Of course, if the air valve inlet opens in the Z-axis direction of the massage air valve cavity 35, then the air delivery port can also open in the Z-axis direction of the massage air valve cavity 35. The air delivery port is connected to the lumbar support air bag interface 32. The lumbar support air valve 6 controls the opening and closing of the air valve inlet and the air valve outlet. The gas flows through the main air inlet 8, the air valve inlet, and the air delivery port into the air bag to form the lumbar support inflation air path.
[0042] In this embodiment, the lumbar support air valve 6 includes a single rocker arm 61, a plug 62, a reset elastic element 63, a memory metal wire 64, and a clamping element 65. One end of the single rocker arm 61 is provided with a plug 62, which corresponds to the air valve inlet and outlet. At least two sets of clamping elements 65 clamp both ends of the memory metal wire 64 and are electrically connected to the circuit board 2. The memory metal wire 64 is sleeved on the forward tilting part 611, with the end of the forward tilting part 611 away from the clamping element 65 tilted forward. The reset elastic element 63 is located on one side of the single rocker arm 61. When the clamping element 65 cuts the memory metal wire 64... After being energized, the memory metal wire 64 retracts, and the reset elastic element 63 abuts against the single rocker arm 61, causing the plug 62 at one end of the single rocker arm 61 to block the air valve inlet or air valve outlet. Of course, only one of the air valve inlet and air valve outlet can be blocked by the plug 62, not both. The single rocker arm 61 opens or blocks the air valve inlet or air valve outlet within the extension and retraction range of the memory metal wire 64. Using a certain support point in the middle attachment of the single rocker arm 61, the waist support air valve cavity 34 swings horizontally. The reset elastic element 53 here can be a spring, a torsion spring, or other elastic element that performs the above function.
[0043] In this embodiment, the rocker arm 61 includes a forward tilting portion 611, which is disposed at one end of the rocker arm 61 near the plug 62.
[0044] In this embodiment, the massage air valve 5 and the waist support air valve 6 control the opening and closing of the air valve inlet and air valve outlet through plugs (52, 62); the massage air valve 5 controls one end of the plug 52 to open the air valve inlet and the other end to close the air valve outlet.
[0045] In this embodiment, only one set of massage air valves 5 is needed to control the inflation and deflation of an air bag. Therefore, multiple sets of massage air valve chambers 35 and massage air valves 5 can be set on the bottom shell 3, corresponding one-to-one with the massage air bag interface 31. Each set of massage air valves 5 can independently control the inflation and deflation of the air bag to achieve the massage function.
[0046] In this embodiment, there are at least two sets of waist support air valves 6 connected in series to control the inflation and deflation of an air bag; one set of waist support air valves 6 controls one end of the plug 62 to open the air valve inlet, and the other set of waist support air valves 6 closes the air valve outlet; since waist massage requires intermittent inflation and deflation of the air bag, the series connection of two sets of waist support air valves 6 to control the air valve inlet and outlet is more conducive to the calculation and control of the control circuit on the circuit board 2.
[0047] In this embodiment, preferably, the plug includes a rubber pad, a hinge, and a clamping part. The hinge connects the clamping part and the rubber pad. The hinge can make the rubber pad seal more tightly with the air valve inlet and air valve outlet, preventing misalignment that could lead to unnecessary continuous inflation or deflation. When the lumbar support air valve 6 and the massage air valve 5 drive the plug to open and close the air valve inlet and air valve outlet, the hinge, being made of soft rubber, is movable.
[0048] In this embodiment, the clamping members (55, 65) are disposed within the snap-fit groove 651 and abut against the snap-fit groove 651, and are electrically connected to the circuit board 2; the clamping members (55, 65) provide power to the massage air valve 5 and the lumbar support air valve 6. The snap-fit groove 651 is disposed within the lumbar support air valve cavity 34 and the massage air valve cavity 35, with one end fixed within the lumbar support air valve cavity 34 and the massage air valve cavity 35, and the other end used to snap the clamping members (55, 65) to prevent the clamping members (55, 65) from detaching;
[0049] In this embodiment, the clamping member (55, 65) includes a short arm 652, a long arm 653, a left foot 654, and a right foot 655; the short arm 652 and the long arm 653 are electrically connected to the circuit board 2, and the left foot 654 and the right foot 655 are engaged in the slot 651; it also includes a folding part 656, which folds inward between the short arm 652 and the long arm 653 or between the left foot 654 and the right foot 655 to clamp the memory metal wire (54, 64). Of course, another clamping member (55, 65) also includes an upper folding part 657 and a lower folding part 658, which alternately fold inward through the short arm 652 and the long arm 653 or between the left foot 654 and the right foot 655 to clamp the memory metal wire (54, 64), just like the fingers of both hands alternately holding an object.
[0050] In this embodiment, the seat air valve control device 100 further includes a foolproof connector 7. The foolproof connector 7 is sleeved on the massage air bag interface 31 and the lumbar support air bag interface 32 to facilitate connection with the air bag of the seat and prevent misconnection. The foolproof connector 7 includes a sealing ring 71, a fitting part 72, and a sound-absorbing plate 73. The fitting part 72 is provided with a sound-absorbing plate 73. The fitting part 72 has an air inlet corresponding to the massage air bag interface 31 and the lumbar support air bag interface 32. The sound-absorbing plate blocks the air inlet when the air bag needs to be sealed. Interface 31 and lumbar support airbag interface 32 extend out of the bottom shell 3 of the seat air valve control device 100 and are sleeved by the foolproof plug 7. The sealing ring 71 is set on the airbag interface 31 and lumbar support airbag interface 32 to prevent air leakage from the airbag interface 31 and lumbar support airbag interface 32. The kit part 72 is sleeved on the airbag interface 31 and lumbar support airbag interface 32. The internal sound damper 73 blocks the air supply port of the airbag interface 31 and lumbar support airbag interface 32 when it is necessary to seal the airbag. The sound damper 73 opens or closes the air supply port as the air pressure is adjusted. The foolproof connector 7 is divided into at least two groups: one group is a three-air-path foolproof connector 7, and the other group is a two-air-path foolproof connector 7. This division into two groups is also to prevent reverse insertion. Of course, it can also be divided into multiple specific groups as needed, all for connecting the massage air bag interface 31 or the lumbar support air bag interface 32. When the foolproof connector 7 is connected to the air bag on the car seat, it uses an offset groove 74 in conjunction with an eccentric setting to prevent reverse connection, which is also a foolproof method when connecting the air bag. The outer surface of the three-air-path foolproof connector is not connected to the massage air bag interface, while the outer surface of the connector connected to the car seat is fixed. The outer surface of the two-air-path foolproof connector 7 is not connected to the massage air bag interface, while the outer surface of the connector connected to the car seat is fixed. The reason for not connecting the outer surface near the massage air bag interface is that if it were connected, it would be difficult to assemble due to manufacturing precision issues. Therefore, this outer surface is intentionally disconnected. The connection to the car seat is made for both ease of connection and foolproof prevention.
[0051] A connecting protrusion 75 is provided on any one of the three-channel foolproof connectors 7. The connecting protrusion 75 on one channel of the foolproof connector 7 is close to another channel of the foolproof connector 7, but is not connected to it. In existing products, the connecting protrusions connect the foolproof connectors in pairs. However, due to manufacturing errors, it is difficult to match with the massage air bag interface 31 of the massage air valve on the bottom shell, which restricts the freedom of the foolproof connector 7. Therefore, the connecting protrusion 75 is provided to achieve foolproofing on the one hand, and to give the foolproof connector 7 freedom on the other hand.
[0052] In this embodiment, the seat air valve control device 100 further includes a vent valve 4, which is disposed on the bottom shell 3 to prevent excessive pressure in the seat air valve control device 100 and to prevent it from affecting the working effect of the memory metal wire.
[0053] In this embodiment, the vent valve 4 is provided with sound-absorbing cotton.
[0054] In this embodiment, the thickness of the massage valve chamber 35 and the lumbar support valve chamber 34 on the bottom shell 3 is 2-8mm, preferably 2.8mm. The thinner thickness adjusts the thickness of the seat valve control device, allowing more other control units or components to be installed in the space inside the seat.
[0055] In this embodiment, the thickness of the massage air valve 5 and the waist support air valve 6 within the massage air valve cavity 35 and the waist support air valve cavity 34 is 1.5-7mm, preferably 2mm.
[0056] In this embodiment, after the upper cover 1 and the bottom shell 3 are closed, a sealed space is formed. Of course, due to assembly needs, multiple sealing ports 33 are opened on the bottom shell 3. After the upper cover 1 and the bottom shell 3 are closed, sealant can be filled into the sealing ports 33 by ultrasonic waves to seal the sealing ports.
[0057] Example 2: This utility model provides a technical solution: a massage chair, which includes an air bag and the aforementioned chair air valve control device 100, wherein the air inlet is connected to the massage air bag interface 31 and the lumbar support air bag interface 32; the massage air bag interface 31 and the lumbar support air bag interface 32 are connected to the air bag; the lumbar support inflation air passage 110 and the massage inflation air passage 120 provide an air source for the air bag.
[0058] The air bag is connected to the air inlet for air release. The seat air valve control device 100 controls the massage air valve 5 and the lumbar support air valve 6 to open the air valve exhaust port, and release the gas in the air bag through the massage air release path and the lumbar support air release path.
[0059] Example 3: This utility model provides a technical solution: a car, including the massage seat described above.
