[0021] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings. The above description is simplified for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0022] The singular forms "a", "said" and "the" used in the specification include plural forms unless clearly indicated. The terms "include", "comprises" and "comprising" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features.

[0023] In the specification, when an element is referred to as being “on,” “fixed” to, “connected to,” “engaged to,” or the like, the element may be directly on, fixed to, connected to, engaged to, or contacting the other element, or intervening elements may be present.

[0024] It is to 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 element. Therefore, a first element may be referred to as a second element without departing from the teachings of the present application.

[0025] The following will describe exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in a variety of 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 drawings, the same reference numerals represent the same or functionally identical elements.

[0026] Figure 2 An integrated bracket for configuring a modular air supply unit is shown. The integrated bracket 20 is mainly composed of a top plate 21 as a bearing body, and the gas tank 1, the compressor 2, the electronic control unit 3 and the distribution valve 4 are hung therein in the form of modules in turn, thereby forming a small modular assembly that can be directly installed on the vehicle body and frame.

[0027] Combined with reference Figure 3 and Figure 4 , a pair of first columns 25a and second columns 25b extending downward as the main supports are provided at the bottom of the top plate 21, and the gas tank 1 and the compressor 2 are mounted on the opposite sides of the first column 25a and the second column 25b respectively. A side plate 23 extending downward in the same direction as the first column 25a and the second column 25b is also provided at the bottom of the bottom plate 21. The side plate 23 and the first column 25a and the second column 25b together form a cage-shaped frame structure to wrap the compressor 2 therein. The air supply unit 10 is arranged on the side of the side plate 23 away from the compressor 2, and the distribution valve 4 is also fixed to the bottom of the top plate 21 through a U-shaped bracket 22. A wire pipe groove 26 is provided between the first column 25a and the second column 25b, and the wire pipe groove 26 is located on the lower side of the gas tank 1.

[0028] The integrated bracket 20 is specifically fixed to the vehicle body or frame through a pair of mounting brackets 27 extending upward from the top plate 21, and the first column 25a and the second column 25b are placed on the central axis 27a of the mounting bracket 27. Since the gas tank 1 has a large mass and volume, it is arranged separately on one side of the central axis 27a, while the compressor 2, the electronic control unit 3 and the distribution valve 4 are placed on the other side to balance the weight distribution with the gas tank 1. The compressor 2 is centrally placed relative to other components, so that the adverse effects of its working vibration on the module can be minimized.

[0029] Figure 5 It is shown that the integrated unit 10 is fixed under the vehicle frame or body as an integral independent assembly module.
