Description

Technical Field

[0001] The present invention relates to the technical field of automobile chassis, and in particular to a central air source valve island and a vehicle. Background Art

[0002] With the development of the automotive industry, overall vehicle comfort has become a core competitive advantage for mid- to high-end vehicles. The current market features a number of functional modules to enhance comfort: air suspension systems use distribution valves to control air springs at each wheel to adjust vehicle posture; tire inflation and deflation systems dynamically adjust tire pressure based on road conditions to optimize grip; in-cabin oxygen concentrators improve oxygen supply in high-altitude environments; seats with integrated massage and side bolster functions enhance the passenger experience; and additional modules include external inflation and deflating functions.

[0003] These functional modules are dispersed throughout the vehicle, each equipped with independent pneumatic or electric devices. This reduces chassis space utilization. Multiple independent air systems and power units require complex wiring harnesses to connect to the power supply, increasing overall harness length and the number of connectors. This also increases the risk of electrical failures (such as short circuits and signal loss) due to harness wear and loose connectors. Furthermore, the duplication of power units, such as air pumps and motors, significantly increases vehicle mass, contradicting lightweight design goals and impacting fuel economy and range.

[0004] In summary, although existing technologies have achieved the diversification of vehicle body functions, their decentralized functional modules and independent power system designs have led to problems such as low space utilization, high wiring harness complexity, and increased weight. A solution with a higher degree of integration and a simpler structure is urgently needed to optimize vehicle performance. Summary of the Invention

If there are more tire valves and tires, the same applies). This application does not limit the upper limit of air suspension airbag valves and tire valves to 4. If the vehicle has more than 4 air suspension airbags and / or tires, more air suspension airbag valves and / or tire valves can be added on the basis of the 4 air suspension airbag valves and / or tire valves.

[0031] The high-pressure module 11 also includes a pressure sensor 112, which is arranged on the air path connecting the air tank supply valve 111 and the air suspension airbag valve group 113. The pressure sensor 112 is used to detect the air pressure in the air path. When the air pressure in the air path is greater than the air pressure of the suspension airbag to be inflated or the tire to be inflated (hereinafter referred to as the air pressure meeting the standard), the corresponding air suspension airbag valve or tire valve is allowed to be opened to inflate the corresponding air suspension airbag or tire.

[0032] The air inlet of the air compressor high-pressure air supply valve 4 is connected to the air compressor high-pressure chamber, the air outlet of the air compressor first air inlet valve 5 is connected to the air compressor air inlet, and the air inlet of the gas tank supply valve 111 is connected to the high-pressure gas storage tank 3.

[0033] When the air compressor high-pressure air supply valve 4, the air compressor first air intake valve 5, and the tire valve group air intake control valve 1141 are in the closed state, the air tank air supply valve 111 is in the open state, and the air pressure meets the standard, any air suspension airbag valve can be opened, and the gas in the high-pressure air tank 3 can be used to inflate any air suspension airbag; when the air compressor first air intake valve 5, the air tank air supply valve 111, and the tire valve group air intake control valve 1141 are in the closed state, the air compressor high-pressure air supply valve 4 is in the open state, and the air pressure meets the standard, any air suspension airbag valve can be opened, and the air compressor can be used to inflate any air suspension airbag; when the air compressor high-pressure air supply valve 4, the air tank air supply valve 111, and the tire valve group air intake control valve 1141 are in the closed state, and the air compressor first air intake valve 5 is in the open state, any air suspension airbag valve can be opened to exhaust any air suspension airbag. Of course, when the air compressor high-pressure air supply valve 4, the air compressor first air intake valve 5, the air tank air supply valve 111, and the tire valve group air intake control valve 1141 are in the closed state, multiple air suspension airbag valves can be opened to quickly balance the air pressure of multiple air suspension airbags.

[0034] When the air compressor high-pressure air supply valve 4, the air compressor first air inlet valve 5, the air suspension airbag valve group 113, and the tire valve group air outlet control valve 1146 are in the closed state, the tire valve group air inlet control valve 1141 and the air tank air supply valve 111 are in the open state, and the air pressure meets the standard, any tire valve can be opened and the gas in the high-pressure air tank 3 can be used to inflate any tire; when the air tank air supply valve 111, the air compressor first air inlet valve 5, the air suspension airbag valve group 113, and the tire valve group air outlet control valve 1146 are in the In the closed state, with the tire valve assembly inlet control valve 1141 and the air compressor high-pressure air supply valve 4 open and the air pressure meeting the standard, any tire valve can be opened to inflate any tire using the air compressor. When the tire valve assembly inlet control valve 1141 is closed, the tire valve assembly outlet control valve 1146 and the corresponding tire valve can be opened to deflate the corresponding tire. The tire valve assembly outlet backpressure valve 1147 stops deflation when the air pressure at the air inlet falls below a preset value, preventing excessive deflation and tire damage. Of course, multiple tire valves can also be opened while the tire valve assembly inlet control valve 1141 and tire valve assembly outlet control valve 1146 are closed to quickly balance the air pressure across multiple tires.

When the air outlet valve 1212 of the external air-consuming equipment is in a closed state and the air inlet valve 1211 of the air-consuming equipment is in an open state, the external air-consuming equipment 24 can be inflated; when the air inlet valve 1211 of the air-consuming equipment is in a closed state and the air outlet valve 1212 of the external air-consuming equipment is in an open state, the external air-consuming equipment 24 can be quickly exhausted, thereby realizing corresponding energy recovery.

[0039] The oxygen concentrator pressure reducing valve 1221, the seat massage pressure reducing valve 1222, and the seat side support pressure reducing valve 1223 can reduce the air source of the air compressor to a preset air pressure, and transmit the reduced-pressure air source to the corresponding on-board gas equipment. When the on-board gas equipment needs to use gas or inflate, it can open the corresponding switch valve and the air compressor low-pressure air supply valve 6 for use or inflation.
