The internal heating assembly 35 can be sealingly connected to the hole in the side wall of the shell of the drying tank 31.

[0039] In this embodiment, the built-in heating component 35 includes a heat-conducting outer shell 351 located within the desiccant 36 and a heating element 356 disposed inside the heat-conducting outer shell 351. The first end of the heat-conducting outer shell 351 is connected to the drying tank 31, and a terminal connector 352 is provided on the outside of the drying tank 31 and inserted into the first end of the heat-conducting outer shell 351. The terminal connector 352 is connected to the heating element 356 through a connecting wire harness 355. The heat-conducting outer shell 351 can transfer the heat generated by the heating element 356 to the heat dissipation component 37.

[0041] Meanwhile, a first temperature sensor 353 connected to a terminal connector 352 is installed at the second end of the heat-conducting housing 351. The first temperature sensor 353 can monitor the temperature of the desiccant.

[0042] As a specific embodiment of the heat dissipation component 37, the heat dissipation component 37 includes a bushing 371 sleeved on the outside of the heat-conducting shell 351 and a plurality of fins 372 arranged around the bushing. The bushing 371 can transfer the heat of the heat-conducting shell 351 to the fins 372. The fins 372 are in full contact with the desiccant 36, which can improve the regeneration speed of the desiccant 36. The fins 372 are arranged radially, and the length of the fins 372 can be adjusted according to the internal space of the drying tank 31 shell to be as long as possible to cover the desiccant 36.

[0043] like Figures 7-9As shown, in another specific embodiment of the dryer assembly 3, the heating component is an external heating assembly 7 disposed on the outside of the drying tank 31 corresponding to the position of the desiccant 36. The external heating assembly 7 includes a heating element 74 disposed on the side wall of the drying tank 31 and a heat insulation sleeve 75 that wraps the heating element 74. The heating element 74 is connected to an external power source through a conductive component.

As a preferred embodiment, the second temperature sensor 73 includes a sensor element 731 and at least one conductive connector 733 connecting the sensor element 731 to a PIN pin 72. The conductive connector 733 is provided with a mounting support block 732. The sensor element 731 is connected and supported by the conductive connector 733. The mounting support block facilitates the fixing of the conductive connector.

[0048] In this embodiment, a venting pad 40 is installed at one end of the desiccant 36 near the air inlet 33. One side of the venting pad 40 is connected to one end of the compression spring 39, and an end cap 38 is installed at the other end of the compression spring 39. The compression spring 39 can apply pressure to the venting pad to compact the desiccant. After compaction, the desiccant can fully contact the heat dissipation component, improving the regeneration efficiency. At the same time, a needle-punched felt 42 and a plastic pad 41 are sequentially arranged at one end of the desiccant 36 near the air outlet 32. The plastic pad 41 has a hollow hole in the middle corresponding to the air outlet 32 ​​to prevent the desiccant 36 from blocking the air outlet 32 ​​and to ensure smooth air passage.

[0049] In this embodiment, as Figure 10 As shown, the switching valve assembly includes an exhaust valve EV connected to the intake and exhaust assembly 6, a first switching valve SV1 and a second switching valve SV2 connected to the air passage of the vehicle air suspension module A, a fourth switching valve SV4 disposed on the air passage between the dryer assembly 3 and the air tank 12, and a third switching valve SV3 disposed on the air passage between the air tank 12 and the air intake end of the integrated valve body 2. The first switching valve SV1 and the second switching valve SV2 are also connected to the air intake end of the dryer assembly 3 and the integrated valve body 2 through the air passage. An air pressure detection unit 14 is provided on the air passage between the first switching valve SV1 and the vehicle air suspension module A.

[0050] The first switching valve SV1 is also connected to the air path of the manual venting component 11, which allows for manual venting when gas needs to be released from the system, improving operational flexibility. Simultaneously, the switching valve assembly also includes a power limiting valve 13, which is connected to both the inlet and outlet of the booster pump assembly. When the system pressure reaches a fixed value, the power limiting valve 13 opens, releasing some gas to prevent excessive pressure within the system.

[0051] By switching the switching valve assembly, the front and rear axles of the vehicle can be raised or lowered, the overall vehicle height can be adjusted according to the vehicle speed, gas exchange can be performed between the air tank and the front and rear springs, and the dryer can be heated and regenerated.

[0052] The integrated air supply unit described in this embodiment has the following operating modes:

[0053] 1. Gas can be drawn directly from the atmosphere into the gas storage tank and pressurized, and a certain amount of gas can be compressed into the gas storage tank by a compressor for storage and use;

[0054] 2. The gas in the air tank can be pumped to the front or rear axle, or the air springs of the front or rear axles, through the switching valve assembly via the compressor, thereby raising the entire vehicle.

[0055] 3. The air in the air spring can be pumped into the air tank for storage and use by the compressor through the switching valve assembly, while the vehicle body is lowered.

[0056] 4. The air in the atmosphere can be directly pumped into the air spring through the compressor and the switching valve assembly, thereby raising the vehicle body.

[0057] 5. By switching the switching valve assembly, gas measurement in the gas storage tank can be achieved, and gas can be replenished or released.

[0058] 6. By switching the valve assembly, the gas in the gas storage tank can be discharged in reverse to the desiccant, and the moisture in the desiccant can be discharged from the system by the airflow.

[0059] 7. By switching the valve assembly, the gas in the air spring and the air tank can be connected when the motor is not working, so as to balance the pressure and balance the pressure before and after the compressor, thereby reducing the torque when the motor starts; at the same time, the connected gas can be used to adjust the vehicle height, saving energy consumption.

[0060] 8. If the pressure in the detection system is too high, the excessive pressure can be discharged by switching the switching valve assembly; alternatively, the power limiting valve can be used to stabilize the maximum system pressure at a certain value to prevent damage to gas components.

[0061] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.
