[0017] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. The above description is for the convenience of describing the present utility model and simplifies the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0018] The singular forms "a", "the", and "said" used in the specification include the plural forms unless clearly specified. The terms "including", "comprising", and "containing" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features.

[0019] In the specification, when it is said that an element is "on", "fixed to", "connected to", "joined to", etc. another element, the element may be directly on, fixed to, connected to, joined to, or in contact with another element, or there may be an intermediate element.

[0020] It can be understood that although the terms "first", "second", etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Therefore, the first element may be referred to as the second element without departing from the teachings of the concept of the present application.

[0021] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all the drawings, the same reference numerals denote the same or functionally identical elements.

[0022] Reference Figure 2 For an integrated lower plate support mounting seat, the airbag 3, shock absorber 4, thrust rod 1 and stabilizer bar 2 are all tightly connected and fixed through the plate support mounting seat 20. The plate support mounting seat 20 has a flat plate-shaped seat plate 25 as the main body. The connection points of the thrust rod 1 and the stabilizer bar 2 with the plate support mounting seat 20 are located on the lower side of the seat plate 25, and the connection and fixing points of the airbag 3 and the shock absorber 4 with the plate support mounting seat 20 are located on the upper side of the seat plate 25, so that the thrust rod 1 and the stabilizer bar 2 and the airbag 3 and the shock absorber 4 converge towards the central axis 5 with each other, and their Y-direction positions are closer to form a compact and balanced structure. The seat plate 25 serves as the bearing main body at this connection, and the preferred thickness range is 24 to 25 mm, made of Q235B steel. The rated load of the airbag 3 is 35 KN.

[0023] Combined with reference Figure 3 and Figure 4 On the seat plate 25, a pair of positioning blocks 21 and convex blocks 22 are provided. The convex block 22 extends forward from the seat plate 25 so that the lower fixing point of the shock absorber 4 can be hinged on the convex block 22 to achieve fixation. The airbag 3 is fixed on the upper side of the seat plate 25 through the airbag mounting seat 30 at its bottom. Since the airbag mounting seat 30 is also fixedly connected to the axle, positioning blocks 21 are provided on the seat plate 25 so that the airbag mounting seat 30 can be more easily positioned when installed with the plate support mounting seat 20.

[0024] On the bottom of the seat plate 25, a first connection seat 23 and a second connection seat 24 are respectively provided. The first connection seat 23 is used to connect with the thrust rod 1, and the second connection seat 24 is used to connect with the stabilizer bar 2.

[0025] In summary, this kind of plate support mounting seat 20 actually simplifies and replaces its original complex beam-shaped connection structure with a flat plate-shaped seat plate 25. Thus, the volume of the lower fixing structure of the suspension is reduced, and at the same time, the two 16 KN airbags 3 in the original structure are replaced with one 35 KN airbag 3.
