Technical Field

[0001] The present application relates to the technical field of pneumatic devices, and in particular to a pneumatic integrated valve group. Background Art

[0002] As society increasingly prioritizes healthy living, car seats are increasingly becoming more user-friendly and intelligent, aiming to improve user experience while alleviating discomfort caused by poor sitting posture. Existing car seats feature airbags surrounding the seat cushion. When a person sits down, a pneumatic system inflates and deflates the airbags, wrapping and supporting the buttocks, which in turn encourages the person to maintain a straight back and a correct sitting posture.

[0003] However, existing pneumatic devices all require manual control and cannot respond in time when a person sits in the seat. Therefore, there is an urgent need to provide a pneumatic device that can respond in time. Summary of the Invention

[0004] The purpose of this application is to provide a pneumatic integrated valve group to solve the problem that the pneumatic device cannot respond in time when a person sits in a seat.

[0005] The pneumatic integrated valve group provided in this application adopts the following technical solution:

The seat includes a seat cushion and several support cushions arranged around the seat cushion. A support airbag is arranged in the support cushion. The seat cushion is provided with a weight sensor connected to the control module. The pneumatic device includes a connecting airbag, a control valve, and an air pump arranged on the seat. The connecting airbag is connected to the support airbag. The connecting airbag and the air pump are both connected to the control valve. The control module is connected to the air pump and the control valve. The connecting airbag is provided with an exhaust pipe. The exhaust pipe is provided with a first solenoid valve and a first flowmeter connected to the control module.

[0007] By adopting the above technical solution, when a person sits in the seat and applies force to the seat cushion, the weight sensor in the seat cushion is triggered, and the weight sensor transmits a signal to the control module. The control module sends a signal to the air pump and the control valve. The air pump is pneumatically inlet, and the control valve fills the air delivered by the air pump into the support airbag through the connecting airbag, thereby forming support for the buttocks. Through the support on both sides, people unconsciously maintain a straight back and an upright sitting posture, disperse the pressure on the buttocks, and can achieve a timely and corresponding effect.

[0008] At the same time, the pressure concentrated in the middle of the buttocks is decomposed to the surrounding areas of the buttocks, tightening the buttocks to achieve the effect of beautiful buttocks.

[0009] And, by collecting and calculating the pressure on the passenger's hips, through data accumulation and calculation, the control module can adjust and disperse the pressure on the hips according to the weight signal fed back by the weight sensor by controlling the air intake of the air pump through the control valve.

[0010] When the person leaves the seat, the weight sensor transmits a signal to the control module again, the control module sends a signal to the first electromagnetic valve to open the exhaust pipe for exhaust, and the first flowmeter feeds back the exhaust amount to the control module, when the exhaust amount is consistent with the air intake amount, the control module sends a signal to the first electromagnetic valve to close the exhaust pipe, realizing the reset of the connecting air bag and the supporting air bag.

[0011] Optionally, the seat is provided with a mounting plate, the connecting air bag is arranged in the mounting plate, the mounting plate is provided with a trigger assembly corresponding to the connecting air bag and connected with the control module, and the pneumatic device further comprises a plurality of buffer air bags, the buffer air bags are connected with the connecting air bag through a connecting pipe, and the connecting pipe is provided with a second electromagnetic valve and a second flowmeter connected with the control module.

[0012] By adopting the above technical scheme, when a person with large hips sits in the seat, he cannot completely sit in the plurality of supporting air bags before sitting on the cushion, so when he sits in the seat, he will squeeze the gas in the supporting air bag into the connecting air bag, the connecting air bag expands to trigger the trigger assembly, the trigger assembly transmits a signal to the control module, the control module sends a signal to the second electromagnetic valve to open the connecting pipe, and the second flowmeter feeds back the gas flow to the control module, so that the gas in the connecting air bag can enter the buffer air bag through the connecting pipe, and the gas in the supporting air bag can be discharged quickly, facilitating the person to sit on the cushion as soon as possible.

[0013] When the person's hips pass through the supporting air bag and sit on the cushion, the weight sensor transmits a signal to the control module, the control module sends a signal to the second electromagnetic valve, and sends a signal to the air pump and the control valve, the air pump pneumatically intakes air, and the control valve charges the air delivered by the air pump into the supporting air bag through the connecting air bag, forming support for the hips.

[0015] When a person with a large buttock area sits on the seat, the gas in the supporting air bag is extruded into the connecting air bag, the connecting air bag expands, and the connecting air bag abuts against one end of the sliding rod, so as to drive the sliding rod to move towards the sliding groove, at this time, the first reset member is elastically deformed under force, and when the end of the sliding rod away from the connecting air bag abuts against the first trigger switch, a signal is transmitted to the control module, the control module sends a signal to the second electromagnetic valve, the connecting pipe is opened, and the second flow meter feeds back the gas flow to the control module, so that the gas in the connecting air bag can enter the buffer air bag through the connecting pipe, and the gas discharge of the supporting air bag can be accelerated.

[0016] When the buttocks of a person sit on the cushion, the weight sensor transmits a signal to the control module, the control module sends a signal to the second electromagnetic valve, and sends a signal to the air pump and the control valve, the second electromagnetic valve closes the connecting pipe, the air pump pneumatically intakes air, and the control valve fills the air delivered by the air pump into the supporting air bag through the connecting air bag to form support for the buttocks; at the same time, too much gas in the connecting air bag also expands and can open the buffer air bag through the sliding rod triggering the first trigger switch, which can not only play a buffering effect, but also avoid the discomfort caused by excessive gas in the supporting air bag pressing the buttocks.

[0017] When the buttocks of a person leave the cushion, the weight sensor transmits a signal to the control module, the control module sends a signal to the first electromagnetic valve to open the exhaust pipe for exhaust, the connecting air bag is exhausted through the exhaust pipe, and the gas in the buffer air bag inflates the connecting air bag, which can not only accelerate the exhaust, but also fill the gas into the supporting air bag to improve the efficiency of the supporting air bag reset.

[0018] When the connecting air bag resets, the first reset member also elastically resets to drive the sliding rod to reset.

At this time, the air pump is still inhaling air, and the user has not stopped the air pump through the control module. One end of the connected airbag abutting contact part extends out of the sliding part, and the second reset part is elastically deformed by the force. One end of the sliding part triggers the second trigger switch, and the second trigger switch transmits a signal to the control module. The control module sends a signal to the air pump and the control valve, and the air pump stops working.

[0025] Optionally, the connecting pipe is provided with a flow valve.

[0044] The implementation principle of a pneumatic integrated valve group in the embodiment of the present application is as follows:

[0045] When a person sits in seat 1 and applies force to seat cushion 13, the weight sensor within seat cushion 13 is triggered. The weight sensor transmits a signal to control module 2, which then signals air pump 33 and control valve 32. Air pump 33 pneumatically inflates, and control valve 32 pumps the air delivered by air pump 33 into support airbag 141 via connecting airbag 31, providing support for the buttocks. This support on both sides unconsciously encourages the person to maintain a straight back and an upright sitting posture, distributing the pressure on the buttocks and achieving a timely and appropriate effect. At the same time, the pressure concentrated in the center of the buttocks is distributed around the buttocks, tightening the buttocks and achieving a beautiful buttocks effect. Furthermore, by collecting and calculating the pressure on the passenger's buttocks and accumulating the data, control module 2 can control the air intake of air pump 33 by controlling control valve 32 based on the weight signal fed back by the weight sensor, adaptively adjusting and distributing the pressure on the buttocks.

[0046] When a person with a larger buttocks area sits in the seat 1, the gas in the supporting airbag 141 squeezes into the connecting airbag 31. After the connecting airbag 31 expands, the connecting airbag 31 abuts one end of the sliding rod 42, driving the sliding rod 42 to move toward the sliding groove 41. At this time, the first reset member 44 is elastically deformed by the force. When the end of the sliding rod 42 away from the connecting airbag 31 abuts against the first trigger switch 43, the signal is transmitted to the control module 2. The control module 2 sends a signal to the second solenoid valve 381 to open the connecting pipe 38. The second flowmeter 382 feeds back the gas flow to the control module 2, so that the gas in the connecting airbag 31 can enter the cache airbag 37 through the connecting pipe 38, which can speed up the discharge of the gas from the supporting airbag 141.

[0047] When a person's buttocks sits on the seat cushion 13, the weight sensor transmits a signal to the control module 2, and the control module 2 sends a signal to the second solenoid valve 381, and sends a signal to the air pump 33 and the control valve 32. The second solenoid valve 381 closes the connecting pipe 38, and the air pump 33 pneumatically intakes air. The control valve 32 fills the air delivered by the air pump 33 into the support airbag 141 through the connecting airbag 31 to form support for the buttocks; at the same time, if the gas in the connecting airbag 31 is excessive and expands, the first trigger switch 43 can be triggered by the sliding rod 42 to open the cache airbag 37, which can not only have a buffering effect, but also avoid the excessive gas in the support airbag 141 from causing pressure on the person's buttocks and causing discomfort.

[0048] When the person's buttocks leave the seat cushion 13, the weight sensor transmits a signal to the control module 2, and the control module 2 sends a signal to the first solenoid valve 35 to open the exhaust pipe 34 for exhaust. The connecting airbag 31 is exhausted through the exhaust pipe 34, and the gas in the cache airbag 37 is inflated to the connecting airbag 31, which can speed up the exhaust and also fill the gas into the supporting airbag 141, thereby improving the efficiency of the resetting of the supporting airbag 141.

[0049] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
