[0029] Figures 1 to 3 The air drying device and air suspension system provided by the utility model are shown. As can be seen from the figure, the air drying device of the utility model includes a first accommodating unit 110 and a second accommodating unit 120; the first accommodating unit 110 has a first accommodating chamber 111, a first connecting hole 112 and a first opening 113; the first connecting hole 112 and the first opening 113 can communicate with the first accommodating chamber 111; the first accommodating chamber 111 is used to accommodate a moisture adsorbent; the first opening 113 is used to communicate with the air outlet of the compressor; the second accommodating unit 12 ... There is a second accommodating chamber 121, a second connecting hole 122 and a second opening 123; the second connecting hole 122 and the second opening 123 can connect the second accommodating chamber 121; the second accommodating chamber 121 is used to accommodate a moisture adsorbent; the second opening 123 is used to connect to the air inlet of the general air-conditioning device; wherein, the periphery of the first connecting hole 112 is connected to the periphery of the second connecting hole 122 to connect the first connecting hole 112 and the second connecting hole 122, and a heat dissipation gap 100 is provided between the cavity wall of the first accommodating chamber 111 and the cavity wall of the second accommodating chamber 121.

[0030] In specific implementation, compared with the traditional air drying device which only uses a single partition to divide the interior of the drying tank into a first accommodating chamber 111 and a second accommodating chamber 121, the air drying device in the utility model innovatively sets an independent first accommodating unit 110 and a second accommodating unit 120, and ensures that there is a heat dissipation gap 100 between the cavity walls of the two accommodating units (the first accommodating unit 110 and the second accommodating unit 120). Therefore, when the moisture adsorbent in the first accommodating chamber 111 generates heat in the process of adsorbing moisture, the heat is no longer directly transferred to the moisture adsorbent in the second accommodating chamber 121 through the partition, but can be effectively dissipated through the heat dissipation gap 100, thereby significantly improving the heat exchange efficiency of the moisture adsorbent, and further ensuring that the moisture adsorbent can be restored to a suitable temperature in a shorter time to maintain better adsorption performance. In summary, the utility model not only optimizes the working efficiency of the air drying device through the above-mentioned structural setting, but also prolongs the service life of the moisture adsorbent, thereby improving the stability and reliability of the entire air suspension system. The technical problem in the prior art that the heat of the moisture adsorbent in the drying tank cannot be quickly released due to the first accommodating chamber 111 and the second accommodating chamber 121 sharing a partition is solved.

[0031] In this embodiment, the first accommodating cavity 111 and the second accommodating cavity 121 may be columnar; the moisture adsorbent may be a molecular sieve; and the diameter of the first connecting hole 112 and the second connecting hole 122 may be 4 mm to 8 mm.

[0032] According to an embodiment of the present invention, a connecting unit 130 is further included, and the connecting unit 130 connects the first accommodating unit 110 and the second accommodating unit 120 .

[0033] During specific implementation, the connection unit 130 enhances the overall structural strength of the air drying device, and ensures a stable connection between the first accommodating unit 110 and the second accommodating unit 120 .

[0034] In this embodiment, the air drying device includes a first end 101 and a second end 102 arranged opposite to each other along its height direction H; the first accommodating unit 110 and the second accommodating unit 120 are arranged side by side along a direction perpendicular to the height direction H of the air drying device; the first opening 113 and the second opening 123 are arranged at the first end 101; the first connecting hole 112 and the second connecting hole 122 are arranged at the second end 102; the connecting unit 130 is located at the first end 101 and is clamped between the side wall of the first accommodating unit 110 and the side wall of the second accommodating unit 120.

[0035] According to one embodiment of the utility model, a first air resistance portion 1110 is provided on the side wall of the first accommodating cavity 111, and the first air resistance portion 1110 is configured as a protrusion or a groove; a second air resistance portion 1210 is provided on the side wall of the second accommodating cavity 121, and the second air resistance portion 1210 is configured as a protrusion or a groove.

[0036] During specific implementation, air chokes are respectively arranged in the first accommodating chamber 111 and the second accommodating chamber 121. The air chokes are designed to be in the form of protrusions or grooves, which can disrupt the flow of air, help increase the contact area and time between the air and the moisture adsorbent, improve the adsorption efficiency of the moisture adsorbent, and effectively control the air flow speed to prevent air flow short circuit, thereby ensuring that the gas passes through the adsorbent sufficiently.

[0037] According to an embodiment of the present invention, a first limiting unit is further included, which is disposed in the first accommodating cavity 111 and located at the first opening 113. The outer peripheral wall of the first limiting unit is connected to the inner peripheral wall of the first accommodating cavity 111. The first limiting unit has a first air through hole, and the first limiting unit is used to limit the moisture adsorbent from moving out of the first accommodating cavity 111 through the first opening 113. In this embodiment, the first limiting unit abuts against the surface of the moisture adsorbent when the moisture adsorbent is placed in the first accommodating cavity 111, so that the moisture adsorbent is in a compacted state.

[0038] In specific implementation, if the above-mentioned structural setting is not adopted, the moisture adsorbent will move under the action of air pressure, causing mutual friction between the moisture adsorbents, and the mutual friction will cause the moisture adsorbent to wear. For example, the moisture adsorbent will change from large particles to small particles, thereby affecting the drying effect; through the above-mentioned structural setting, the moisture adsorbent can be restricted (equivalent to locking) to prevent the moisture adsorbent from moving in the first accommodating cavity 111, thereby preventing mutual friction between the moisture adsorbents, thereby ensuring the drying effect of the air drying device of the utility model.

[0039] According to an embodiment of the present invention, a second limiting unit is further included, which is disposed in the second accommodating cavity 121 and located at the second opening 123. The outer peripheral wall of the second limiting unit is connected to the inner peripheral wall of the second accommodating cavity 121. The second limiting unit has a second air through hole, and the second limiting unit is used to limit the moisture adsorbent from moving out of the second accommodating cavity 121 through the second opening 123. In this embodiment, the second limiting unit abuts against the surface of the moisture adsorbent when the moisture adsorbent is placed in the second accommodating cavity 121, so that the moisture adsorbent is in a compacted state.

[0040] In specific implementation, the above-mentioned structural setting can prevent the moisture adsorbent in the second accommodating chamber 121 from entering the gas-using device in the positive direction from the second accommodating chamber 121, wherein the positive direction is along the direction from the compressor to the gas-using device, and the positive direction generally corresponds to the usage scenario where the vehicle height needs to be increased.

[0041] The utility model also provides an air suspension system, including the air drying device of the above embodiment. Applying the air drying device of the above embodiment to the air suspension system can effectively remove moisture from the compressed air, reduce the impact of moisture on the air suspension system components, especially the damage to the air-using device (such as the air spring), improve the reliability and service life of the air suspension system, and reduce the maintenance cost.
