[0028] The application will be described in further detail below with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not intended to limit the scope of the application. In addition, it should be noted that only parts related to the application are shown in the drawings for ease of description.

[0030] Embodiment 1

[0031] As mentioned in the background, in order to solve the problems in the prior art, the present application provides a vehicle seat pneumatic function air inlet and outlet system 11, which has a first space 17 inside the seat, as shown in Figure 1 and Figure 5 The air inlet and outlet system comprises:

[0032] An air source assembly 3 is arranged in the first space 17, and the air source assembly 3 has an air inlet end 9 and an air outlet end 8;

[0033] Optionally, the first space 17 is the seat interior space of the vehicle, and the air inlet and outlet system is controlled by a controller 19. If the controller 19 is equipped with a gas collecting device, the gas in the first space 17 can be discharged out of the first space 17 through the gas pipe of the gas collecting device. In this case, the first space 17 can be a closed space. In addition, if the controller 19 is not equipped with a gas collecting device, the first space 17 cannot be completely closed, and the gas in the first space 17 needs to be discharged out of the first space 17.

[0034] An air outlet pipe 4 is in communication with the air outlet end 8 of the air source assembly 3, and the air outlet pipe 4 is used to transport the compressed gas generated by the air source assembly 3;

[0035] Specifically, the air outlet pipe 4 is made of TPU, PU, rubber or plastic material which is pressure-resistant, corrosion-resistant and bendable. The air outlet pipe 4 is led out from the air outlet end 8 of the air source assembly 3 and is arranged according to the specific conditions of the first space 17. The air outlet pipe 4 can be laid along the bulkhead of the seat to avoid hindering the normal operation of the equipment. The air outlet pipe 4 can also be arranged spirally on the seat framework to achieve the cooling effect of the first space 17. The air outlet port 41 of the air outlet pipe 4 away from the air outlet end 8 can be connected to the equipment or system which needs to be filled with compressed gas, such as pneumatic tools, seat adjusting devices, etc.

[0036] An air inlet pipe 5 is in communication with the air inlet end 9 of the air source assembly 3, and an air inlet 22 of the air inlet pipe 5, which is away from the air inlet end 9, is arranged outside the first space 17.

[0037] Specifically, the air inlet pipe 5 is also made of a durable and bendable material, and its length is determined according to the distance between the air source assembly 3 and the air inlet 22 outside the first space 17. One end of the air inlet pipe 5 is connected to the air inlet end 9 of the air source assembly 3, and the other end extends to the outside of the first space 17 through the wall surface or other suitable openings of the first space 17. The position of the air inlet 22 should be selected in a place with lower temperature and cleaner air to avoid inhaling impurities such as dust and oil stains.

[0038] For example, the air inlet 22 can be arranged in a hidden area of the backrest of a car seat, or in a well-ventilated area inside the car cabin, or connected to a special air filtering device before introducing external air.

[0039] The use process of the air inlet and outlet system 11 is as follows: after the air source assembly 3 is started, cold air is inhaled from the outside of the first space 17 through the air inlet pipe 5. Since the air inlet 22 is arranged outside the first space 17, the air source assembly 3 can obtain fresh air with lower temperature, avoiding inhaling the heated gas in the first space 17. The air source assembly 3 compresses the inhaled air, and the generated compressed gas is delivered to the equipment or system that needs to be filled with compressed gas through the air outlet pipe 4. If the air outlet pipe 4 coils on the seat frame, the compressed gas will exchange heat with the air in the first space 17 during the flow process, thereby reducing the temperature in the first space 17. During the entire operation process, the air source assembly 3 continuously obtains cold air from the outside of the first space 17, ensuring the normal operation and cooling effect of the air source assembly 3, and also helping to maintain the temperature stability in the first space 17.

[0040] In a preferred embodiment, please refer to Figure 2 The air inlet 22 of the air inlet pipe 5 is in communication with a cooling air source outside the first space 17, and the gas temperature of the cooling air source is lower than that of the first space 17.

[0041] Further, please refer to Figure 3 The air inlet pipe 5 is in communication with the air conditioner outlet pipe 13 outside the first space 17 through the air inlet 22, and the air conditioner outlet pipe 13 is connected to the air conditioner outlet 12.

[0042] Specifically, the air inlet pipe 5 is connected to the air conditioner outlet pipe 13 outside the first space 17 through a special joint or adapter. The connection should ensure good sealing to prevent gas leakage. Specifically, the air inlet pipe 5 can be passed through the vehicle body panel from the inside of the seat and connected to the air outlet pipe of the vehicle air conditioning system.

[0043] Optionally, the air conditioner outlet pipe 13 is appropriately modified and adjusted. For example, branch pipes or valves are added to better control the flow of cooling gas to the air inlet pipe 5. A filter or screen is provided near the connection point to prevent dust, impurities, etc. in the air conditioning system from entering the air inlet pipe 5 and the gas source assembly 3.

[0044] Before the gas source assembly 3 is needed, the air conditioning system connected to it is started. Ensure that the air conditioning system is set at an appropriate temperature and air speed to provide a low-temperature gas flow with sufficient cooling effect. After the gas source assembly 3 is started, low-temperature cooling gas is drawn from the air conditioner outlet pipe 13 through the air inlet pipe 5. Because the temperature of the cooling gas source is lower than the temperature of the gas in the first space 17, the gas source assembly 3 can operate in a lower temperature environment, improving the performance and life of the gas source assembly 3. According to the actual needs of the gas source assembly 3 and the capacity of the air conditioning system, the cooling gas flow into the air inlet pipe 5 can be controlled by adjusting the opening of the valve or branch pipe on the air conditioner outlet pipe 13. At the same time, different cooling gas supply situations can also be adapted by adjusting the speed or working mode of the gas source assembly 3.

[0045] In a preferred embodiment, the gas source assembly 3 is a gas pump, which includes a housing having a mounting space inside, a pump body provided in the mounting space, the pump body having the air inlet end 9 and the air outlet end 8, the housing having a first opening and a second opening, the first opening having the air outlet pipe 4, and the second opening having the air inlet pipe 5. The gas source assembly 3 can also include a silencing element 6 and a wire sheath 10.

[0046] Further, in the mounting space, the pump body is connected to a damping part 7 at one end along its extension direction, and the damping part 7 is in abutment with the inner surface of the housing away from the pump body.

[0047] Specifically, the damping part 7 is made of a high-elasticity material, such as rubber, silicone, etc., which can effectively absorb the vibration and impact force generated during the operation of the gas source assembly 3.

[0048] The design of the damping part 7 can significantly reduce the vibration transmitted to the surrounding structure during the operation of the air source assembly 3, reduce the generation of noise, and improve the stability and reliability of the entire system. At the same time, it can also protect the pump body and the components connected thereto from excessive vibration damage and prolong the service life of the equipment. The shape and size of the damping part 7 can be customized according to the specific specifications and installation requirements of the air source assembly 3. It can be ring-shaped, block-shaped or other specific shapes to ensure close fit with the air source assembly 3 and provide effective damping effect in all directions.

[0049] Specifically, the air source assembly 3 can be arranged near the cooling gas source or away from the cooling gas source. When the air source assembly 3 is arranged near the cooling gas source, the length of the air inlet pipe 5 is shortened, reducing the resistance of gas flowing in the air inlet pipe 5, enabling the air source assembly 3 to suck in low-temperature cooling gas more quickly and directly. This helps to improve the air intake efficiency of the air source assembly 3, reduce power consumption, and enhance the overall performance of the air source assembly 3. The shortened air inlet pipe 5 also reduces heat absorption during gas transmission, ensuring that the temperature of the gas entering the air source assembly 3 remains at a low level, further enhancing the cooling effect. In addition, arranging the air source assembly 3 near the cooling gas source can simplify the installation process. The length of the air inlet pipe 5 is shorter, requiring less space and materials during installation, reducing installation costs and difficulty. At the same time, it also reduces the risk of leakage and failure due to excessive length of the pipe. In addition, in some relatively compact space layouts, arranging the air source assembly 3 near the cooling gas source can better utilize the space. This layout can make the entire air intake and exhaust system 11 more compact and tidy, avoiding the chaotic distribution of pipes and improving space utilization.

[0050] In a preferred embodiment, referring to Figure 4 the air inlet pipe 5 is coiled within the first space 17.

[0051] Specifically, coiling the air inlet pipe 5 within the first space 17 can have a certain temperature regulation effect. When the cooling gas flows in the air inlet pipe 5, it exchanges heat with the air in the first space 17, thereby reducing the temperature in the first space 17. Especially in some cases where the temperature of the entire space needs to be controlled, this method can assist in temperature regulation to some extent and improve overall energy utilization efficiency. In addition, in some cases, arranging the air source assembly 3 away from the cooling gas source can avoid the air source assembly 3 from being affected by the vibration, noise or other adverse effects of the cooling gas source. The coiled air inlet pipe 5 can have a certain buffering effect, reducing the influence of external interference on the air source assembly 3 and protecting the normal operation and service life of the air source assembly 3.

[0052] In a preferred embodiment, the air inlet pipe 5 is provided with a filter element 21 near the air inlet 22 for filtering impurities in the gas entering the air inlet pipe 5.

[0053] Specifically, the filter element 21 is an air cleaner, a filter screen, a filter cartridge, or the like.

[0054] In a preferred embodiment, a controller 19 is further included for controlling the compressed gas generated by the gas source assembly 3 to enter the gas using assembly, and for controlling the compressed gas discharged from the gas using assembly to be discharged into the first space 17.

[0055] Specifically, when certain conditions are met, for example, when the gas using assembly needs to work, the controller 19 sends a signal to open the channel between the gas source assembly 3 and the gas using assembly, so that the compressed gas flows from the gas source assembly 3 to the gas using assembly. During the use of the compressed gas by the gas using assembly, the controller can adjust the amount of gas entering the gas using assembly as needed to ensure the normal operation of the gas using assembly. When the gas using assembly completes the work or an abnormal situation occurs and the compressed gas needs to be discharged, the controller sends a signal again to open the channel between the gas using assembly and the first space 17, and the compressed gas is discharged into the first space 17.

[0056] In a preferred embodiment, the controller 19 is provided with a gas collecting device, which can collect the compressed gas in the controller 19 and discharge it out of the first space 17.

[0057] Specifically, when the valve inside the controller 19 discharges the compressed gas, the gas collecting device can collect the discharged compressed gas, and discharge the compressed gas out of the first space 17 through the exhaust pipe connected to the gas collecting device, so as to avoid the temperature of the compressed gas rising and causing the temperature of the first space 17 to rise.

[0058] Embodiment 2

[0059] Based on embodiment 1, please refer to Figure 5 As shown in the figure, the embodiment proposes a vehicle seat, which has the air inlet and outlet system 11 as described above.

[0060] Specifically, the vehicle seat has a cover layer 14, a soft layer 15, and a foaming layer 16, the foaming layer 16 has a buckle cover 18 away from the side of the soft layer 15, the buckle cover 18 has a space for installing the air inlet and outlet system 11 between the buckle cover 18 and the foaming layer 16, the space is the first space 17, the first space 17 is provided with a mounting back plate 20, the mounting back plate 20 is provided with a controller 19 for controlling the air inlet and outlet system 11, the controller 19 generates heat during operation, which causes the temperature of the gas in the first space 17 to rise. Therefore, the air inlet pipe 5 of the air inlet and outlet system in the scheme is placed outside the first space 17, which can avoid the high-temperature gas in the first space 17 being sucked into the air source assembly 3, and ensure the working efficiency of the air source assembly 3.
