Compared with sheet metal parts of steel structures in the prior art, the aluminum alloy integrated die-casting structure is lighter in weight and beneficial to weight reduction of the vehicle body. In some embodiments, the strength of the aluminum alloy integral die-cast structure can further improve the connection stability between the base 100 and the vehicle body compared to the welding method, and avoid the risk of off-welding. The stability of connection to the base 100 can be improved by providing the support structure 200, and an impact force transmitted to the base 100 by the air spring (not shown) can be resisted, thereby improving the impact resistance of the air spring mount 10.

In some embodiments, the air spring may be an air spring for a vehicle shock absorbing structure and the air spring mount 10 may be an air spring mount.
The base 100 may include a limiting protrusion 120 and a reinforcing structure 130, where the limiting protrusion 120 is disposed on the mounting surface 110 and extends away from the supporting structure 200, and the limiting protrusion 120 is used for limiting connection with the air spring. In some embodiments, a groove (not shown in the drawings) matched with the limiting protrusion 120 is formed on a side of the hollow spring facing the mounting surface 110, the limiting protrusion 120 can be inserted into the groove, the movement of the hollow spring in the axial direction can be limited by the limiting protrusion 120, the displacement of the hollow spring in the radial direction can be limited, and the connection stability of the hollow spring and the hollow spring mounting seat 10 can be improved by the limiting protrusion 120.

The installation connection of the air spring and the air spring installation seat 10 can be facilitated by providing the pre-hanging structure 300.
Furthermore, since the notch of the mounting groove 230 faces the outside of the vehicle body and can communicate with the inside of the mounting groove 230 and the outside of the vehicle body, the connection condition of the hanging piece and the pre-hanging structure 300 can be conveniently observed by an operator in the process that the hanging piece of the air spring penetrates into the first through hole 140 and the second through hole 310 to be hung, and the practicability of the air spring mounting seat 10 is improved.
