[0080] In this embodiment, an air storage module is provided. When the air intake of the air intake module is greater than the gas amount required by the inflation module, the excess gas is stored in the air storage module, thereby avoiding excessive air intake. At the same time, a stable air intake volume can be provided for the inflation module, thereby achieving stable adjustment of the air spring.

[0081] In this embodiment, the valve core 9 of the solenoid valve controls the air passage formed by the plastic shell to control the inflation and deflation of the air spring.

[0082] The gas distribution valve of this embodiment has a total of six air pipe quick connectors, which correspond to four air springs, an air storage tank, and an air compressor. The compressor end and the air storage tank are air inlets, which are respectively connected to five solenoid valves. The solenoid valve opens when the power is turned on, and closes when the power is turned off. The solenoid valve is a normally closed solenoid valve. The solenoid valve is composed of a front yoke 14, a coil 13, a rear yoke 16, a moving iron core 10, a shell part 801 and a valve body part 802 of a magnetic isolation sleeve 8, and a spring. After the power is turned on, the coil 13 is energized to generate electromagnetic force, the moving iron core 10 compresses the spring and attracts the rear yoke 11, the valve opens, and the gas enters the valve body part 802 of the magnetic isolation sleeve 8 through the plastic shell airway, and then enters the air spring. When inflating, a gas pressure sensor is provided at the air inlet to detect the pressure in real time. After the inflation pressure is reached, the signal is fed back to the control unit, the controller is powered off, and the reset spring pushes the moving iron core 10 to close the valve.

The moving iron core 10 and the spring need to be installed before welding. The coil 13 is installed in the front yoke 14, and then the valve body assembly welded in the previous step is installed. The valve body assembly and the front yoke 14 are fixed by interference fit.

[0084] After the front yoke 14 and the valve body assembly are riveted, the PCB board is installed, and the PCB board is welded with 10 pins of the solenoid valve, 3 pins of the sensor, and 10 pins of the plug assembly by soldering.

[0085] After welding is completed, glue filling or sealing welding is carried out.

[0087] This embodiment solves the problems of complex process, heavy weight, large volume and many types of parts in the traditional split design by setting the valve body and the magnetic isolation sleeve of the solenoid valve into an integrated structure. The valve body and the magnetic isolation sleeve of the traditional solution are connected by welding, and air leakage at the weld often occurs, causing product failure. The valve body and the magnetic isolation sleeve of this embodiment are integrated and there is no air leakage.

[0088] The integrated design reduces the number of parts and manufacturing costs. The length of the integrated design is more than 10mm shorter than the traditional structure, which allows the thickness of the plastic shell to be designed with greater weight reduction space. Compared with the traditional structure, the overall product weight is reduced by more than 25%. For new energy vehicles, the lighter the weight, the lower the energy consumption.

[0089] The front yoke 14 is fixed to the plastic shell by hot-melt process. This embodiment reduces the types of parts and reduces costs. Traditionally, a front yoke needs to be welded on the magnetic isolation sleeve, and then the front yoke and the plastic shell 1 are hot-melt riveted. This embodiment solves the problem of heavy product weight. The front yoke 14 and the plastic shell are directly dissolved to reduce the product thickness again. At the same time, the glue filling volume is smaller, and the product weight is reduced again. Reduced energy consumption.

[0090] This embodiment also provides an automobile suspension chassis, including the above-mentioned gas distribution valve with pressure relief function.

[0091] The utility model welds and seals the distributing valve housing through the sealing bottom cover, thus avoiding the collapse of the sealing structure when the pressure is too high. At the same time, a waterproof and breathable membrane is arranged on the sealing bottom cover, which can slowly release the excessive pressure.
