[0040] Specifically, Figure 1 , Figure 2 and Figure 5As shown, a pair of the shell components 1 are divided into an upper shell component and a lower shell component, and the upper shell component and the lower shell component both include a first shell 8, and the upper shell component and the lower shell component can be mutually engaged through their respective first shells 8, and after engagement, the first space is formed between the pair of first shells 8; the lower shell component is provided with a connecting leg 18, and the connecting leg 18 is provided with a connecting hole, and the connecting leg 18 is used to connect the controller with the internal structure of the vehicle seat; the connecting hole can be a connecting hole or a threaded hole. The first inner cavity 2 is provided on at least one side wall of the shell component 1, so as to prevent the noise generated in the first space from passing through the shell component 1 to the outside, thereby improving the comfort during use.

[0041] Specifically, the control valve 3 is a two-position three-way valve, or a two-position three-way valve and a two-position two-way valve are connected in series. Optionally, the control valve 3 is a solenoid valve or a memory alloy valve. A plurality of the control valves 3 are arranged along the length direction of the housing assembly 1. A plurality of the control valves 3 can be arranged on one side or two opposite sides of the housing assembly 1. The air inlet ends 19 of all the control valves 3 in each row are connected to each other and to the air inlet nozzle 4. The air inlet nozzle 4 is installed in the first space and extends out of the first space. The position of the air inlet nozzle 4 is as shown in FIG. Figure 4 As shown; the outlet end 5 of each control valve 3 extends out of the first space from the side of the housing assembly 1, and the exhaust end 6 of each control valve 3 is connected to the first space, such as Figure 3 As shown; the air inlet nozzle 4 is used to connect the air source component, and each of the air outlet ends 5 can be connected to an air-using component; preferably, the air source component is an air pump, and the air-using component is an air bag. When the air-using component is inflated, the airflow direction of the air outlet end 5 is from the inside of the control valve 3 to the outside; when the air-using component is deflated, the airflow direction of the air outlet end 5 is from the outside to the inside of the control valve 3.

[0042] When it is necessary to inflate the gas-using component, the control valve 3 connects the gas inlet end 19 and the gas outlet end 5, and the gas output by the gas source component is filled into the air bag through the control valve 3 to realize the pneumatic function; when it is necessary to deflate the gas-using component, the control valve 3 connects the gas outlet end 5 and the deflation end 6, and the gas in the air bag enters the first space through the control valve 3, and then is discharged to the outside through the first inner cavity 2. When the gas passes through the first inner cavity 2, it flows rapidly in the first inner cavity 2 to cool the shell component 1, thereby preventing the control valve 3 in the first space from overheating.

[0043] Furthermore, the first inner cavity 2 is also provided on a side wall of the first shell 8 .

[0044] For details, please refer to Figure 4 and Figure 6 The side wall of the first shell 8 is set as a double-layer structure and the double-layer structure is hollow. The hollow structure of the side wall of the first shell 8 also forms the first inner cavity 2, so as to further improve the effect of preventing noise transmission.

[0045] Furthermore, at least one of the housing components 1 comprises:

[0046] A second shell 9, wherein the second shell 9 is disposed on one side of the first shell 8, the first shell 8 and the second shell 9 are connected, and the second shell 9 and the first shell 8 are covered to form the first inner cavity 2; a side of the first shell 8 away from the second shell 9 is covered with the first shell 8 of another shell assembly 1 to form the first space;

[0047] a plurality of first exhaust holes 10, wherein the first exhaust holes 10 are provided on the first shell 8 connected to the second shell 9, and the first exhaust holes 10 are in communication with the first inner cavity 2 and the first space;

[0048] A plurality of second exhaust holes 11 are provided on the second shell 9 , and the second exhaust holes 11 are connected to the first inner cavity 2 and the ambient atmosphere.

[0049] Specifically, Figure 5 As shown, the upper shell assembly includes the second shell 9 in addition to the first shell 8, or the lower shell assembly includes the second shell 9 in addition to the first shell 8, or the upper shell assembly and the lower shell assembly include the second shell 9 in addition to the first shell 8; the first shell 8 and the second shell 9 are both plate-like structures, and the first shell 8 is surrounded by side walls, one side of the first shell 8 and the second shell 9 can be snapped together, and the first inner cavity 2 can be formed between the first shell 8 and the second shell 9 after the snapping; the side wall of the first shell 8 extends in the direction away from the second shell 9; during installation, a pair of first shells 8 are arranged opposite to each other, and the connection between the pair of shell assemblies 1 is achieved by snapping the side walls of the two first shells 8, and the first space is formed between the two first shells 8.

[0050] like Figure 4 and Figure 6 As shown, the first exhaust hole 10 passes through both sides of the first shell 8, and the second exhaust hole 11 passes through both sides of the second shell 9. When the airbag is deflated, the gas in the first space enters the first inner cavity 2 through the first exhaust hole 10, and the gas in the first inner cavity 2 is discharged to the outside of the controller through the second exhaust hole 11.

[0051] Furthermore, a partition 12 is provided on one side of the first shell 8 close to the second shell 9 , and the partition 12 divides the first inner cavity 2 into a plurality of air guide passages, each of which is connected to at least one of the first exhaust holes 10 and one of the second exhaust holes 11 .

[0052] Specifically, Figure 7 and Figure 8 As shown, the partitions 12 are provided in plurality, and the plurality of partitions 12 divide the first inner cavity 2 into a plurality of independent spaces. Some of the partitions 12 are provided with notches 21, and the notches 21 connect two adjacent independent spaces. The independent spaces connected to each other form the air guide path, and the air guide path is composed of at least one independent space. Each of the air guide paths is connected to at least one of the first exhaust holes 10 and one of the second exhaust holes 11, thereby ensuring that each of the air guide paths is connected to the first space and the ambient atmosphere respectively; the first exhaust holes 10 and the second exhaust holes 11 connected to each of the air guide paths can be multiple, such as Figure 7 and Fig. 9 Preferably, the first exhaust hole 10 is arranged at one end of the air guide passage, and the second exhaust hole 11 is arranged at the other end of the air guide passage, so that the gas entering the air guide passage can flow through the entire air guide passage before being discharged, thereby making the area through which the gas flows in the first inner cavity 2 larger, and the area for effective heat dissipation is also larger.

[0053] Furthermore, the controller further comprises a connector assembly 7, which is arranged at one end of a pair of the housing assemblies 1, and the connector assembly 7 is used to electrically connect the control valve 3 and an external device;

[0054] The joint assembly 7 comprises:

[0055] A connecting member 13, wherein the connecting member 13 is engaged with the first housing 8, and an electrical connecting portion 20 is provided inside the connecting member 13, and the electrical connecting portion 20 is electrically connected to the control valve 3;

[0056] A sealing member 14 is sleeved on the connecting member 13 and seals a connection position between the connecting member 13 and the first housing 8 .

[0057] Furthermore, a circuit board 15 is provided in the first space, and the electrical connection portion 20 is electrically connected to the control valve 3 through the circuit board 15. When the control valve 3 is deflated, the holes of the circuit board 15 itself can be used to exhaust downwards, or an independent vent hole can be provided to exhaust downwards.

[0058] Specifically, Figure 1 and Figure 5 As shown, the connector 13 is an electrical connector, and the connector 13 is snap-fitted with the first housing 8; the connector 13 includes the electrical connector 20, and the electrical connector 20 includes a plurality of wiring terminals, one end of which is electrically connected to the control valve 3, and the electrical connector 20 is electrically connected to the control valve 3 through the circuit board 15, so that the vehicle can uniformly control all the control valves 3 or separately control some of the control valves 3. The sealing member 14 is sleeved on the connector 13, and the sealing member 14 can be made of a soft and airtight material. The sealing member 14 seals the connection position between the connector 13 and the first housing 8 to prevent the gas from leaking from the connection position between the sealing member 14 and the first housing 8 and generating noise when the airbag is deflated.

[0059] Furthermore, the sides of the first shell 8 and the second shell 9 that are close to each other are frosted.

[0060] Specifically, by setting the side where the first shell 8 and the second shell 9 are close to each other as a frosted surface, that is, the inner wall of the first inner cavity 2 is a frosted surface, irregular reflections are generated in the first inner cavity 2 when the gas enters the first inner cavity 2, thereby reducing noise.

[0061] Furthermore, a sealing ring 16 is sleeved on the air outlet end 5 , and the sealing ring 16 is used to seal the position where the air outlet end 5 protrudes.

[0062] Specifically, Figure 5 As shown, the air outlet end 5 extends out of the first space from the side of the first shell 8, and the sealing ring 16 is sleeved on the air outlet end 5. The sealing ring 16 is used to seal the position where the air outlet end 5 extends out of the first space, so as to prevent the gas in the first space from leaking from the connection position between the air outlet end 5 and the first shell 8, thereby further reducing the transmission of noise.

[0063] Furthermore, an extension portion 17 is disposed at a position of the first shell 8 corresponding to the air outlet end 5 , and the extension portion 17 surrounds the outside of the air outlet end 5 and does not contact the air outlet end 5 .

[0064] Specifically, Figure 5 As shown, the extension portion 17 is arc-shaped, and the two extension portions 17 at corresponding positions are interlocked to surround the air outlet end 5 and wrap the sealing ring 16 therein; the extension portion 17 is used to protect the air outlet end 5 and the sealing ring 16 on the one hand, and to further reduce the transmission of noise on the other hand.

[0067] Specifically, the air pump is connected to all the air inlet ends 19 through the air inlet nozzle 4, and each of the air outlet ends 5 is individually connected to an air bag. The air pump can be controlled by the controller to inflate the air bag, and can also be controlled to deflate the air bag. When deflated, the noise inside the controller can be effectively reduced from being transmitted to the outside, and the controller can also be effectively cooled by the exhausted gas.
