Vehicle air source distribution device and vehicle air supply system

Abstract

The utility model belongs to the technical field of vehicle air supply systems, and particularly relates to a vehicle air source distribution device and a vehicle air supply system. The gas source distribution device for the vehicle comprises a plurality of stages of pressure reduction units, and the pressure reduction unit of the next stage is connected with the pressure reduction unit of the previous stage so as to reduce the pressure of gas stage by stage; and the plurality of gas output control units are connected with the corresponding pressure reduction units so as to output gas with corresponding pressure.

For some air supply objects which are close to the passengers and execute the pneumatic function, the noise source can be transferred from the previous position close to the passengers to the current position far away from the passengers, and noise, sensed by the passengers, of the air pump and the valve body of the control switch can be reduced.

Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle gas supply system, specifically relating to a vehicle gas source distribution device and a vehicle gas supply system. Background Technology

[0002] As the market penetration rate of electric vehicles gradually increases, electric vehicles have undergone many changes in configuration compared with traditional fuel vehicles. Features such as pneumatic lumbar support, pneumatic massage, air suspension, and camera cleaning are becoming increasingly common in electric vehicles.

[0003] These air-driven functions rely on air pump components. Since these functions have been gradually added to electric vehicles, for example, first there was pneumatic lumbar support, then pneumatic massage was added as an upgrade, and then air suspension was added. Therefore, each of them is equipped with a separate air pump component for air supply. Currently, the number of air pump components in the vehicle is gradually increasing and becoming more scattered. This is beginning to have an adverse impact on assembly during production and the utilization of interior space. Utility Model Content

[0004] The purpose of this utility model 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 components for air supply, resulting in more and more scattered air pump components in the vehicle.

[0005] To solve the above-mentioned technical problems, this utility model provides a vehicle gas distribution device, including: several stages of pressure reduction units, wherein the pressure reduction unit of the next stage is connected to the pressure reduction unit of the previous stage to reduce the gas pressure step by step; and several gas output control units, which are connected to the corresponding pressure reduction units to output gas at the corresponding pressure.

[0006] Furthermore, the pressure reduction unit includes a pressure reduction valve; the input end of the pressure reduction valve of the subsequent pressure reduction unit is connected to the output end of the pressure reduction valve of the preceding pressure reduction unit.

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

[0008] Furthermore, the pressure reduction unit also includes a pressure sensor, which is connected to the output section of the pressure reduction 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, both the pressure reducing valve and the air valve are disposed in a valve seat; the valve seat has several air passages, and the input and output ports of each pressure reducing valve are connected to the corresponding air passages to form the output section of each pressure reducing valve; the input port of each air valve is connected to the air passage corresponding to the output section of the pressure reducing valve of the corresponding pressure reducing unit.

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

[0012] On the other hand, this utility model also provides a vehicle air supply system, including: a high-pressure air source, which is connected to the first step of the vehicle air source distribution device as described above, a pressure reduction unit.

[0013] The beneficial effects of this utility model are that the vehicle air source distribution device and vehicle air supply system provided by this utility model are equipped with several stages of pressure reduction units. The pressure reduction unit of each stage is connected to the pressure reduction unit of the previous stage, which can reduce the gas pressure step by step. Each stage of pressure reduction unit is connected to a gas output control unit, so as to output the depressurized gas to supply air to the vehicle pneumatic function that requires the corresponding gas pressure to operate. Compared with the previously separately equipped miniature air pump assembly, it can provide a larger and more stable air pressure. Moreover, only this vehicle air source distribution device needs to be installed in the vehicle. This vehicle air source distribution device is then connected to each air supply object that performs the pneumatic function through air pipes. There is no need to install air pumps and control switch valves at the air supply objects. The space at the air supply objects can be freed up. For some air supply objects that perform pneumatic functions close to passengers, the noise source can also be moved from the previous location close to passengers to the current location away from passengers. The noise of air pumps and control switch valves perceived by passengers can be reduced. Attached Figure Description
