Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle thermal management technology, and in particular relates to a gas-liquid separator fixing bracket. Background Technology
[0002] With the deepening of the "dual-carbon" strategy, the electrification of commercial vehicles, especially heavy-duty electric tractors, has become a key path for emission reduction in the transportation sector. Thermal management is a core technology that electric vehicles must adopt, and gas-liquid separators are often used in thermal management systems.
[0003] Gas-liquid separators have a cylindrical structure, and their assembly and positioning are mostly controlled by drawing lines or tooling fixtures. Positioning by drawing feature lines requires manual control, resulting in poor assembly accuracy and low production efficiency. Controlling by tooling fixtures can guarantee assembly accuracy, but tooling fixtures require investment, and the assembly efficiency is also not high. Utility Model Content
[0004] The technical problem solved by this utility model is to provide a fixed bracket for a gas-liquid separator, so as to solve the problem of low efficiency caused by the reliance on manual positioning in the assembly and positioning of existing gas-liquid separators.
[0005] The basic solution provided by this utility model is: a gas-liquid separator fixing bracket, comprising a gas-liquid separator, a limiting bracket one, a limiting bracket two, and a mounting bracket, wherein: The gas-liquid separator is provided with an arc-shaped groove at the top; The limiting bracket includes an upper bending part, a lateral limiting part and a lower bending part integrally formed in sequence. The upper bending part is located in the arc-shaped groove at the top of the gas-liquid separator, and the lower bending part is attached to the bottom of the gas-liquid separator. The second limiting bracket includes a U-shaped receiving cavity and mounting parts located at both ends of the opening of the U-shaped receiving cavity; the gas-liquid separator is placed inside the U-shaped receiving cavity, and the mounting parts are fixedly connected to the lateral limiting parts of the first limiting bracket. One side of the mounting bracket is fixed to the lateral limiting part, and the other side is fixed to the whole vehicle.
[0006] Furthermore, the mounting bracket is L-shaped, with the back of the vertical end of the L-shaped mounting bracket welded to the lateral limiting part, and the bottom of the horizontal end of the L-shaped mounting bracket fixed to the vehicle.
[0007] Furthermore, the U-shaped receiving cavity on the second limiting bracket is integrally formed with the mounting parts at both ends of its opening.
[0008] Furthermore, the transverse limiting part is provided with strip-shaped mounting holes at both ends, the limiting bracket two is made of aluminum alloy, and the strip-shaped mounting holes are fixedly connected to the mounting part on the limiting bracket two.
[0009] The principle and advantages of this utility model are as follows: This utility model achieves precise positioning and stable fixation of the gas-liquid separator through the coordinated cooperation of multiple components. Its core principle is as follows: the pre-set arc-shaped groove on the top of the gas-liquid separator and the upper bend of the limiting bracket one form a fitting structure. Combined with the close support of the lower bend of the limiting bracket to the bottom of the gas-liquid separator, the radial displacement of the gas-liquid separator is constrained from the top and bottom. At the same time, the U-shaped receiving cavity of the limiting bracket two wraps around the side wall of the gas-liquid separator, further limiting its radial sway. The mounting part of the limiting bracket two is fixedly connected to the lateral limiting part of the limiting bracket one, forming a lateral positioning frame. Finally, the gas-liquid separator assembly is stably fixed to the vehicle by the mounting brackets respectively fixed to the lateral limiting part and the whole vehicle, realizing axial and radial full-dimensional limiting, and ensuring installation accuracy without additional tooling.
[0010] The advantages are as follows: Firstly, by adapting the design of each bracket to the arc groove and cylindrical sidewall of the gas-liquid separator itself, the cost of special tooling fixtures is eliminated, while avoiding the accuracy error of manual line drawing and positioning, thus achieving a dual improvement in assembly accuracy and economy. Secondly, each bracket adopts an integrated molding or simple fixed connection structure, and the assembly steps are clear. The multi-directional limiting of limit bracket one and limit bracket two, along with the vehicle fixing function of the mounting bracket, are integrated in a coordinated manner, which not only simplifies the assembly process and improves assembly efficiency, but also achieves error-proof assembly through multi-dimensional constraints, meeting the stringent requirements of the vehicle thermal management system for assembly installation accuracy. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the structure of Embodiment 1 of the present utility model; Figure 2 This is a structural schematic diagram of Embodiment 2 of the present invention. Detailed Implementation
[0012] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: gas-liquid separator 1, arc groove 101, limiting bracket one 2, upper bending part 201, lateral limiting part 202, lower bending part 203, strip mounting hole 204, limiting bracket two 3, U-shaped receiving cavity 301, mounting part 302, and mounting bracket 4.
[0013] Example 1: Example 1 is basically as shown in the attached document. Figure 1 As shown: A gas-liquid separator fixing bracket includes a gas-liquid separator 1, a limiting bracket 2, a limiting bracket 3, and a mounting bracket 4, wherein: The gas-liquid separator 1 is provided with an arc-shaped groove 101. When using the gas-liquid separator 1, it is necessary to first conduct an appearance and structural inspection to confirm that the size and position of the top arc-shaped groove 101 meet the design requirements, and that the groove wall is free from deformation and damage, so as to ensure the fitting accuracy with the limiting bracket 1 2. At the same time, check the flatness of the cylindrical side wall of the gas-liquid separator 1 to ensure the fit with the U-shaped receiving cavity 301 of the limiting bracket 2 3.
[0014] The limiting bracket 2 includes an upper bending portion 201, a lateral limiting portion 202, and a lower bending portion 203, which are integrally formed in sequence. The bending shapes of the upper bending portion 201 and the lower bending portion 203 are L-shaped, and the lateral limiting portion 202 is in the shape of an "I". During the integral forming process, one end of the upper bending portion 201 is placed in the arc-shaped groove 101 at the top of the gas-liquid separator 1, and the other end is integrally formed with the middle part of the lateral limiting portion 202. One end of the lower bending portion 203 is placed at the bottom of the gas-liquid separator 1, and the other end is integrally formed with the middle part of the lateral limiting portion 202. Therefore, the limiting bracket 2 appears to be a cross shape when viewed from the front. In this way, the upper bending portion 201 of the limiting bracket 2 limits the rotational movement of the gas-liquid separator 1 along the axial direction by engaging with the arc-shaped groove 101 of the gas-liquid separator 1.
[0015] The limiting bracket 3 includes a U-shaped receiving cavity 301 and mounting portions 302 located at both ends of the opening of the U-shaped receiving cavity 301. In this embodiment, the mounting portions 302 are integrally formed with the opening ends of the U-shaped receiving cavity 301, such as... Figure 1 As shown; during assembly, the gas-liquid separator 1 with the limiting bracket 2 installed is placed into the U-shaped receiving cavity 301 of the limiting bracket 3. The position is adjusted so that the cylindrical side wall of the separator is fully in contact with the inner wall of the U-shaped receiving cavity 301. In this way, the wrapping property of the U-shaped structure is used to further limit the radial sway of the gas-liquid separator 1 in the horizontal direction.
[0016] After the gas-liquid separator 1 is fitted with the U-shaped receiving cavity 301, the mounting part 302 at both ends of the opening of the second limiting bracket 3 is aligned with the preset connection points on the transverse limiting part 202 of the first limiting bracket 2. In this application, the preset connection points are bolt holes. The mounting part 302 and the transverse limiting part 202 are fixedly connected by bolt fastening to form a transverse positioning frame, thereby enhancing the multi-directional limiting effect on the gas-liquid separator 1.
[0017] One side of the mounting bracket 4 is fixed to the lateral limiting part 202, and the other side is fixed to the vehicle. In this embodiment, the mounting bracket 4 is L-shaped. The back of the vertical end of the L-shaped mounting bracket 4 is welded to the lateral limiting part 202, and the bottom of the horizontal end of the L-shaped mounting bracket 4 is fixed to the vehicle. Specifically, the mounting bracket 4 and the lateral limiting part 202 are aligned and welded to ensure a firm connection and avoid assembly gaps. Then, the overall position of the gas-liquid separator 1 assembly is adjusted so that the other end of the mounting bracket 4 is aligned with the preset installation point of the vehicle. The mounting bracket 4 is fixed to the vehicle by bolt connection, thus achieving stable assembly of the gas-liquid separator 1 assembly on the vehicle. The installation accuracy can be guaranteed without special tooling fixtures throughout the process.
[0018] Example 2: The difference between Example 2 and Example 1 is that, in Example 2, as... Figure 2 As shown, the transverse limiting part 202 has strip-shaped mounting holes 204 at both ends. The limiting bracket 202 is made of aluminum alloy. The strip-shaped mounting holes 204 are fixedly connected to the mounting part 302 on the limiting bracket 202.
[0019] Based on the above structure, when installing the limiting bracket 1 2 and the limiting bracket 2 3, after the gas-liquid separator 1 is placed in the U-shaped receiving cavity 301, the aluminum alloy material of the limiting bracket 2 3 can be squeezed and contracted or expanded, so that the U-shaped receiving cavity 301 fits more closely with the cylindrical side wall of the gas-liquid separator 1. At the same time, the U-shaped receiving cavity 301 is more suitable for gas-liquid separators 1 of different sizes. Then, based on the strip mounting hole 204 on the transverse limiting part 202, it is connected to the mounting hole on the mounting part 302 by bolts and anti-slip washers, so that the inner diameter of the U-shaped receiving cavity 301 is fixedly fitted to the cylindrical side wall of the gas-liquid separator 1.
