The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] Please refer to Figure 1-Figure 6, this embodiment provides a pneumatic structure for reducing the temperature of a pneumatic controller, including:

[0031] A pneumatic controller 100, comprising a housing 101, wherein the housing 101 has a first space, wherein the housing 101 is provided with at least one air inlet 102 and an air outlet 108 communicating with the first space; wherein the first space is provided with a plurality of valve bodies 105, wherein the valve bodies include an air inlet 118, an air supply port 106, and an air release port 119;

[0034] Specifically, the shell 101 is a rectangular parallelepiped structure, the interior of the shell 101 is hollow to form the first space, the bottom surface of the shell 101 is provided with a mounting foot 117, the mounting foot 117 is used to connect the controller 100 to the car seat, the top surface of the shell 101 is provided with a plurality of air inlet holes 102, the air inlet holes 102 penetrate the top surface of the shell 101 and are connected to the first space; the valve body 105 is arranged along the length direction of the shell 101, the The valve body 105 includes at least one air inlet 118, one air supply port 106 and one air release port 119; the air inlet 118 and the air release port 119 are both disposed in the housing 101, and the air supply port 106 extends out of the housing 101; the valve body 105 is driven by a solenoid valve or a memory alloy; the number of the airbag body 300 includes at least one, one airbag body 300 is correspondingly connected to one valve body 105, and the airbag body 300 is an air bag for massage or support. The air source assembly 200 includes an air pump and a housing sleeved outside the air pump; the first port 201 and the second port 202 can be set to one or more than one.

[0035] Specifically, a circuit board 116 is provided on the housing 101, and the circuit board 116 is electrically connected to the valve body. The circuit board 116 is used to connect to the vehicle ECU, and the circuit board 116 is used to control the state of each valve body 105 by receiving instructions sent by the vehicle ECU.

[0036] Further, the valve body 105 is a two-position three-way valve body, or a combination of a two-position three-way valve body and a two-position two-way valve body, or a combination of a two-position three-way valve body and a one-way valve.

[0037] When the valve body 105 is a two-position three-way valve, the pneumatic controller 100 provided in this embodiment can realize the inflation and deflation functions of the airbag body 300, which is mainly used for the massage function of the car seat; when the valve body 105 is a combination of a two-position three-way valve body and a two-position two-way valve body or a combination of a two-position three-way and a one-way valve, the pneumatic controller provided in this embodiment can realize the inflation, deflation and pressure-maintaining functions of the airbag body 300, which is mainly used for the support functions of the car seat, such as lumbar support, side support and leg support.

[0038] Furthermore, the housing 101 is provided with an air-guiding passage 103 and at least one air-guiding interface 107 which are connected to each other by air paths, and the air-guiding interface 107 is connected to the first port 201 through a first tube assembly 109; the air inlets 118 of all the valve bodies 105 are connected to the air-guiding passage 103; and the air outlet port 108 is connected to the second port 202 through a second tube assembly 110.

[0039] Specifically, the gas guide interface 107 is arranged on the side wall of the housing 101, and the gas guide interface 107 can be an optional switch valve. The gas guide interface 107 is connected to one end of the gas guide line 103, and the gas guide interface 107 is connected to the first port 201 of the gas source component 200 through the first pipe assembly 109. A sealing steel ball 120 is arranged in the gas guide line 103 to prevent the gas from flowing along the gas guide line 103 to the outside of the pneumatic controller 100. When the gas source component 200 is powered on, the gas emitted from the first port 201 passes through the first pipe assembly 109, the gas guide interface 107, the gas guide passage 103, the gas inlet 118 and the gas supply port 106 of the valve body 105 in sequence and enters the gas bag body 300 to inflate the gas bag body 300; the arrangement of the gas guide line 103 enables multiple gas bags 300 to be inflated at the same time.

[0040] Specifically, the air source component 200 exhausts air from the first port 201 and also takes in air through the second port 202. Since the second port 202 is connected to the first space through the second tube component 110, the air source component 200 will suck the air in the first space into the air source component when it is working, so that the position of the air inlet hole 102 requires air to continuously enter the first space.

[0041] Furthermore, the air inlet 102 is arranged at a position far away from the air outlet port 108. When the air source component 200 is powered on, the air entering the first space through the air inlet 102 will pass through several valve bodies 105 before reaching the air outlet port 108, thereby ensuring that each valve body 105 can be cooled.

[0042] Furthermore, both the first tube assembly 109 and the second tube assembly 110 are flexible, and the inner diameter of the second tube assembly 110 is more than 1.3 times the inner diameter of the first tube assembly 109 .

[0043] Specifically, the first tube assembly 109 and the second tube assembly 110 may be selected as sealed air pipes, and the first tube 109 is sealed at the position where it is connected to the first port 201 and the air guide interface 107, and the second tube 110 is sealed at the position where it is connected to the second port 202 and the air outlet port 108. Since the air source assembly 200 pressurizes the primary air entering from the second port 202 to form secondary air and then discharges it from the first port 201, by setting the inner diameter of the second tube 110 to be more than 1.3 times the inner diameter of the first tube 109, the balance of air outlet and air intake of the air source assembly 200 is ensured; the primary air is low-pressure air, and the secondary air is high-pressure air.

[0044] Furthermore, a gas leakage passage 104 is provided in the first space, and the gas leakage ports 119 of all the valve bodies 105 are connected to the gas leakage passage 104 . The gas leakage passage 104 is connected to the outside of the controller 100 , and the gas discharged from the gas leakage ports 119 is discharged to the outside of the housing 101 .

[0045] Specifically, the valve body 105 is actually used to control whether the gas in the airbag body 300 is connected to the air source device 200, and whether the gas in the airbag body 300 is connected to the ambient atmosphere, which ultimately manifests as the airbag body 300 being inflated, the airbag body 300 being deflated, or the airbag body 300 being pressurized.

[0046] Furthermore, the first space is provided with an air leakage chamber 111 connected to the air leakage passage 104 , the air leakage chamber 111 is provided with an air leakage hole 112 , and the air leakage passage 104 is connected to the ambient atmosphere through the air leakage hole 112 ; the air leakage chamber 111 is filled with a sound-absorbing filter material 113 .

[0047] The gas in the air leakage passage 104 needs to pass through the air leakage chamber 111 before entering the ambient atmosphere. By providing the air leakage chamber 111 and filling the air leakage chamber 111 with a sound-absorbing filter material 113, the noise generated by the gas during the air leakage process can be reduced.

[0048] Furthermore, the first space is provided with an air collecting piece 114 , and the air leakage passage 104 is provided on the air collecting piece 114 ; the air collecting piece 114 is used for sealingly connecting the air leakage passage 104 with the air leakage ports 119 of each valve body 105 and the air leakage passage 104 with the air leakage cavity 111 .

[0049] By providing the gas collecting member 114, the sealing between the gas leakage passage 104 and the gas leakage ports 119 of each valve body 105 and between the gas leakage passage 104 and the gas leakage chamber 111 is improved, so as to avoid the problem of increased noise caused by the gas being discharged into the ambient atmosphere without passing through the sound-absorbing filter material 113 during the gas leakage process. Optionally, the sound-absorbing filter material 113 is a sound-absorbing sponge or a sound-absorbing rubber.

[0050] Furthermore, a plurality of air intake structures 115 communicating with the first space are disposed on the side wall of the housing 101 , and the air intake structures 115 are disposed around the air supply port 106 .

[0051] Specifically, the air intake structure 115 is a gap in the outer shell 101 or an additional hole opened on the side wall of the outer shell 101, and the air intake structure 115 is connected to the first space; by setting the air intake structure 115, when the air source component 200 is working, air can be taken in not only through the air intake hole 102, but also through the air intake structure 115, thereby further improving the purpose of cooling the switch valve 105.

[0053] Based on Example 1, this example provides a combined pneumatic structure, which includes at least two pneumatic structures for reducing the temperature of a pneumatic controller as described in Example 1 connected in series, wherein the second port 202 in the first pneumatic structure is connected to the air outlet port 108 in the second pneumatic structure, and the first port 201 in the second pneumatic structure is connected to the air guide interface 107 in the first pneumatic structure.

[0054] Specifically, in order to improve efficiency, multiple pneumatic controllers 100 and multiple air source components 200 can be alternately connected in series, thereby controlling more cavities 300 to be inflated and deflated; in this embodiment, the combined pneumatic structure includes two pneumatic structures as described in Example 1, such as Figure 7 shown.
