They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] See Figures 1-7 This embodiment provides a fixing bracket 100, which is used to fix a gas-liquid separator, a liquid reservoir, etc., to a vehicle. More specifically, it fixes the gas-liquid separator, the liquid reservoir, etc., to the vehicle frame. This embodiment uses a gas-liquid separator 200 as an example. The fixing bracket 100 includes a first bracket 1 and a second bracket 2, which are fixedly connected by means of snap-fit ​​or other methods. The first bracket 1 includes a first main body 11 and an elastic part 12. The first main body 11 and the elastic part 12 are fixedly connected or integrally formed by injection molding. The first bracket 1 has a first through hole 111, which penetrates the first bracket 1 along its thickness direction. The wall forming the first through hole 111 includes at least the inner wall of the elastic part 12. The first main body 11 includes an inner wall 112. The elastic part 12 is attached to and fixed to the inner wall 112 or integrally formed by injection molding. In this embodiment, the elastic part 12 is a continuous part along the circumference. In other embodiments, the elastic part 12 can also be spaced apart along the circumference and attached to the inner wall. Specifically, the outer wall of the elastic part 12 is attached to and fixed to the inner wall 112 or integrally formed by injection molding. The inner wall of the elastic part 12 has a texture 121. The texture 121 is raised or recessed relative to the inner wall of the elastic part 12. The shape of the texture 121 is not limited. In this embodiment, it is an inclined strip-shaped texture. The texture is beneficial to the friction between the first support 1 and the gas-liquid separator 200, and improves the clamping force of the first support 1 on the gas-liquid separator 200. The outer contour of the first support 1 is close to a circle or ellipse, which can save materials. Of course, the outer contour of the first support 1 can also be as shown in the figure. Figure 8 Other shapes such as rectangles or triangles are shown. See also Figure 9 As shown, the texture 121 of the elastic part 12 can also be an irregular texture.

[0023] See Figure 4 , Figure 5The first main body 11 also has a slot 113, which is provided along the thickness direction of the first bracket 1. The slot 113 may or may not penetrate the first main body 11 along the thickness direction of the first bracket 1. In the attached drawings of this embodiment, the slot 113 is provided along the thickness direction of the first bracket 1. For ease of explanation, the thickness direction of the first bracket 1 is defined as the axial direction, and the direction perpendicular to the thickness direction of the first bracket 1 is defined as the radial direction. Unless otherwise specified, the axial direction refers to the thickness direction of the first bracket 1, and the radial direction refers to the direction perpendicular to the thickness direction of the first bracket 1.

[0024] To reduce the overall vehicle weight, the first main body 11 can be made of plastic materials such as polypropylene (PP). The elastic part 12 is typically made of elastic materials such as rubber or thermoplastic elastomers. In this embodiment, the elastic part 12 is preferably made of thermoplastic vulcanizate (TPV), a type of thermoplastic elastomer. TPV has high hardness and high elasticity, and is easy to process and recycle. The first bracket 1 can be formed by injection molding. First, TPV material is added to the mold and then PP material is added to the mold and then injected. In this way, the elastic part and the first main body are fixed together by injection molding. Of course, the first main body and the elastic part can also be processed separately and then fixed by other methods.

[0025] To ensure the structural strength of the fixed bracket 100, the second bracket 2 is made of steel with high hardness. For example... Figure 2 , 3As shown, the second bracket 2 includes a second main body 21, a first fixing part 22, and a snap-fit ​​part 23. The second main body 21 and the snap-fit ​​part 23 are fixedly connected or integrally formed. The second main body 21 extends axially and forms an approximately 90° angle with the first bracket 1. The snap-fit ​​part 23 is fixedly connected to one end of the second main body 21. Along the thickness direction of the first bracket 1, the first fixing part 22 is located at the end of the second main body 21 away from the first bracket 1. At least a portion of the snap-fit ​​part 23 is located in the slot 113 of the first bracket 1. The snap-fit ​​part 23 and the wall of the slot 113 are interference-fitted, thereby achieving the snap-fit ​​fixation between the second bracket 2 and the first bracket 1. The first fixing part 22 extends radially and is fixedly connected to or integrally formed with the second main body part 21. In this embodiment, the first fixing part 22 and the second main body part 21 are integrally formed. The first fixing part 22 and the second main body part 21 can be directly connected or connected through a bending part. When the first fixing part 22 and the second main body part 21 are directly connected, they are set at approximately a 90° angle. In this embodiment, the second bracket 2 also includes a first bending part 24, which is bent from the second main body part 21 toward the first fixing part 22. The first bending part 24 connects the second main body part 21 and the first fixing part 22. Connecting the second main body part 21 and the first fixing part 22 through the first bending part 24 facilitates the processing and forming of the second bracket 2 and ensures the structural strength of the second bracket 2. In addition, the bending degree of the first bending part 24 can be used to finely adjust the position of the first fixing part 22 to a certain extent. The first fixing part 22 has a notch or notch, and one end of the gas-liquid separator 200 can be fixedly connected to the first fixing part 22 by bolts.

[0026] The second bracket 2 also includes two or more second fixing parts 25, which are used to fix the bracket to the frame. When there are two second fixing parts 25, they are located on the radial sides of the second main body 21, respectively. This design prevents the second bracket 2 from being fixed to the frame on one side, which helps to make the force between the frame and the second bracket 2 more even. In this embodiment, there are three second fixing parts 25, two of which are located on the same side passing through the second main body 21, and the third is located on the other side of the second main body 21. The second fixing parts 25 have notches or holes, and the frame can be fixedly connected to the second fixing parts 25 by bolts. Similar to the first fixing part 22, the second bracket 2 also includes a second bending part 26, which connects the second fixing part 25 and the second main body 21.

[0027] The second bracket 2 also includes a positioning part 27, which is fixedly connected to or integrally formed with the second main body 21. The positioning part 27 has a positioning hole 271, and the frame has a mating part, such as a positioning post. The positioning hole 271 and the positioning post are mated together for positioning. In other embodiments, the structures of the positioning part and the mating part can be interchanged. For example, the positioning part 27 can be a positioning post, and the corresponding mating part has a positioning hole. The second main body 21 also has a riveting hole 211. The second bracket 2 can be riveted and fixed to the frame through the riveting hole 211, or it can be threadedly fixed to the frame through the second fixing part 25. There are various connection methods.

[0028] This embodiment also provides a gas-liquid separator 200, which includes a container 210 and a fixed support 100. See below. Figure 6 and Figure 7 This is a schematic diagram of the structure after the fixed bracket 100 and the canned container 210 are assembled. The gas-liquid separator 200 includes the canned container 210, the first bracket 1 is sleeved on the outer periphery of the canned container 210, part of the canned container 210 is located in the first through hole 111, the elastic part 12 abuts between the canned container 210 and the first main body part 11, the side of the elastic part 12 with the texture 121 is in close contact with the canned container 210 and abuts against it, the first bracket 1 and the canned container 210 are interference fit to achieve the function of radial fixation. When the gas-liquid separator 200 is fixed on the vehicle frame, the vehicle frame will vibrate in various directions during the operation of the vehicle, so the gas-liquid separator 200 fixed on the vehicle frame is also prone to vibration, and the elastic part 12 can better absorb the vibration from the radial direction. The lower end of the gas-liquid separator 200 is fixedly connected to the first fixing part 22 by bolts to achieve axial fixation. In order to reduce the vibration of the gas-liquid separator 200, a shock-absorbing pad 300 is provided between the first fixing part 22 and the lower end of the gas-liquid separator 200.

[0029] This embodiment also provides a vehicle, including a frame, a fixed bracket 100, and a canning container 210, the frame of which is not shown in the drawings. A positioning part 27 engages with a positioning post of the frame, and a second fixing part 25 is fixedly connected to the frame by bolts. A certain gap exists between the second main body part 21 and the canning container 210, and a second bending part 26 bends from the second main body part 21 towards the canning container 210. To reduce vibration of the gas-liquid separator 200 and facilitate the connection between the gas-liquid separator 200 and the interface pipeline, a shock-absorbing pad 300 can be provided between the second fixing part 25 and the frame, and a shock-absorbing pad 300 is also provided between the first fixing part 22 and the lower end of the gas-liquid separator 200. Combined with the elastic part radially located on the canning container 210 of the gas-liquid separator 200, the gas-liquid separator 200 can effectively absorb vibrations from all directions of the frame, and can absorb dimensional and positional tolerances of the interface pipeline in all directions to a large extent, which is beneficial for the connection between the gas-liquid separator 200 and the interface pipeline. In addition, the first bracket 1 and the second bracket 2 are snap-fitted together, which facilitates disassembly, installation of the gas-liquid separator 200, and connection for interface management, making it easy to replace and maintain.

[0030] See Figure 10 This is a second embodiment of the gas-liquid separator 200. Unlike the previous embodiment, in this embodiment, the snap-fit ​​part 23 extends a certain length along the axial direction. By lengthening the snap-fit ​​part 23, the installation height of the gas-liquid separator 200 can be adjusted within this length range. For example, when the current height of the first bracket 1 is too low, a certain force can be applied to the snap-fit ​​part 23 and the first bracket 1 to move the first bracket 1 upward a certain distance, thereby achieving the purpose of adjusting the height.
