Functions such as pneumatic lumbar support, pneumatic massage, air suspension and camera cleaning are becoming more and more popular in electric vehicles.

[0003] These functions that require air drive are inseparable from air pump components. Since these functions are gradually added to electric vehicles, for example, first there is a pneumatic lumbar support, then the configuration is upgraded to add pneumatic massage, and then air suspension is added, so they are all equipped with separate air pump components for air supply. At present, the air pump components in the car are gradually becoming more and more numerous and scattered, which has begun to have an adverse effect on assembly during production and utilization of space in the car. Summary of the invention

[0004] The purpose of the present invention is to provide a vehicle air source distribution device and a vehicle air supply system to solve the technical problem that the current vehicle pneumatic functions are all equipped with separate air pump assemblies for air supply, resulting in an increasing number of scattered air pump assemblies in the vehicle.

[0005] In order to solve the above technical problems, the present invention provides a vehicle gas source distribution device, including: a plurality of pressure reducing units, the pressure reducing unit of the latter stage is connected to the pressure reducing unit of the previous stage to reduce the pressure of the gas step by step; a plurality of gas output control units, which are connected to the corresponding pressure reducing units to output gas of corresponding pressure.

[0006] Furthermore, the pressure reducing unit comprises: a pressure reducing valve; an input end of the pressure reducing valve of the pressure reducing unit of the next stage is connected to an output end of the pressure reducing valve of the pressure reducing unit of the previous stage.

[0007] Furthermore, the pressure reducing unit further includes: a pressure relief valve which is connected to the output section of the pressure reducing valve.

[0008] Furthermore, the pressure reducing unit further comprises: a pressure sensor which is connected to the output section of the pressure reducing valve.

[0009] Furthermore, the gas output control unit includes: a gas valve, which is connected to the output section of the pressure reducing valve of the corresponding pressure reducing unit.

[0010] Furthermore, the pressure reducing valve and the gas valve are both arranged in a valve seat; a plurality of air duct sections are opened in the valve seat, and the input end and output end channels of each pressure reducing valve are connected to the corresponding air duct to form the output section of each pressure reducing valve; the input end of each gas valve is connected to the air duct channel corresponding to the output section of the pressure reducing valve of the corresponding pressure reducing unit.

[0011] Furthermore, an output air pipe quick plug is provided on the valve seat, and each output air pipe quick plug is connected to the output end channel of the corresponding air valve.

[0012] On the other hand, the present invention further provides a vehicle air supply system, comprising: a high-pressure air source, which is connected to the first pressure reduction unit of the vehicle air source distribution device as described above.

[0013] The beneficial effect of the present invention is that the vehicle air source distribution device and vehicle air supply system provided by the present invention are provided with several levels of step-down units, and the step-down unit of the latter level is connected to the step-down unit of the previous level, so as to reduce the pressure of the gas step by step, and each level of the step-down unit is connected to a gas output control unit, so as to output the reduced-pressure gas to supply the vehicle pneumatic functions that require gas of corresponding air pressure to operate. Compared with the previously separately equipped miniature air pump assembly, it can provide a larger and more stable air pressure, and only the vehicle air source distribution device needs to be set up in the vehicle, and the vehicle air source distribution device is then connected to each air supply object that performs pneumatic functions through an air pipe. It is no longer necessary to set an air pump and a valve body of a control switch at the air supply object, and the space at the air supply object can be released. For some air supply objects that perform pneumatic functions close to passengers, the noise source can also be transferred from the previous close position to the current far away position from the passengers, and the noise of the air pump and the valve body of the control switch perceived by the passengers can be reduced.
