Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The gas-liquid separator plays a vital role in the air conditioning system. Its main function is to separate the liquid refrigerant from the refrigerant before it enters the compressor to prevent the liquid from entering the compressor and causing liquid hammer, thereby protecting the normal operation of the compressor and extending its service life. However, in the actual installation process, the fixed position of the gas-liquid separator may be affected by space limitations or design layout, resulting in the possibility of rotation after it is fixed. This rotation may cause the refrigerant pipeline to interfere with other surrounding components, affecting the stability and safety of the system.

[0039] The related art adopts locking bolts and stop washers to ensure that the gas-liquid separator will not rotate due to external force or vibration after being fixed, but such installation and fixing is more complicated, and if it is arranged in a certain position of the vehicle body, it is difficult to install due to limited space, and there is still a problem of rotation interference after the fixing bolts are loosened. The related art also solves the problem of rotation after fixing by welding the bracket to the gas-liquid separator, but it increases the weight and cost of the gas-liquid separator.

[0040] In order to effectively solve the rotation interference problem of the gas-liquid separator after being fixed and ensure the stable operation of the air conditioning system, the utility model proposes a gas-liquid separator. The gas-liquid separator is applied to the air conditioning system of the vehicle, and the vehicle is provided with a mounting bracket for assembling the gas-liquid separator, and the mounting bracket can be arranged at multiple positions of the vehicle body around the compressor of the air conditioning system.

[0041] See also Figures 1 to 5 In one embodiment of the utility model, the gas-liquid separator 100 includes an upper cover 110, a tank body 120 and a lower cover 130. The upper cover 110, the tank body 120 and the lower cover 130 are connected in sequence to form a refrigerant accommodating chamber (not shown in the figure). The upper cover 110 or the lower cover 130 is respectively provided with an inlet 140 and an outlet 150 for the refrigerant to enter and exit; the upper cover 110 and the lower cover 130 are sealed and connected to the tank body 120 to ensure the airtightness of the internal refrigerant circulation system.

[0042] The upper cover 110 is located at the top of the gas-liquid separator 100. The tank body 120 is also called the main body or shell, which is the main part of the gas-liquid separator 100. The refrigerant receiving chamber is formed inside to ensure that the refrigerant has enough time to separate the gas and liquid before entering the compressor. The lower cover 130 is located at the bottom of the gas-liquid separator 100. Figure 1 The inlet 140 and the outlet 150 extend from the lower cover 130. The inlet 140 is used to guide the refrigerant into the separator, and the outlet 150 is used to discharge the separated gaseous refrigerant, which will be sent to the compressor for the next cycle. Without loss of generality, the inlet 140 and the outlet 150 can also be arranged on the upper cover 110 or one is arranged on the upper cover 110 and the other is arranged on the lower cover 130 according to different models of the gas-liquid separator 100.

[0043] The tank body 120 can be integrally formed as a sealed container, and the lower cover 130 and the upper cover 110 are separate parts attached to the tank body 120, such as by welding them together or fixing them by locking, etc.; the upper cover 110, the tank body 120, and the lower cover 130 can also be integrally formed, and the integral forming means that the various components are formed into a whole through a manufacturing process.

[0044] In order to solve the rotation problem of the gas-liquid separator 100 after being fixed on the mounting bracket 200, the mounting bracket 200 is provided with a limiting portion 220, see Figures 1 to 5 In one embodiment, the upper cover 110 is provided with a positioning portion 160 that is self-lockingly engaged with the limiting portion 220; in another embodiment, the tank body 120 is provided with a positioning portion 160 that is self-lockingly engaged with the limiting portion 220; in yet another embodiment, the lower cover 130 is provided with a positioning portion 160 that is self-lockingly engaged with the limiting portion 220; in other embodiments, both the upper cover 110 and the lower cover 130 are provided with a positioning portion 160 that is self-lockingly engaged with the limiting portion 220; in other embodiments, both the upper cover 110 and the tank body 120 are provided with a positioning portion 160 that is self-lockingly engaged with the limiting portion 220; in other embodiments, both the tank body 120 and the lower cover 130 are provided with a positioning portion 160 that is self-lockingly engaged with the limiting portion 220; in other embodiments, the upper cover 110, the tank body 120 and the lower cover 130 are provided with a positioning portion 160 that is self-lockingly engaged with the limiting portion 220.

[0045] Self-locking snap-fit ​​means that the structural body used for snap-fit ​​has the characteristic of preventing relative rotation. One component can automatically lock after being inserted into another component to prevent it from falling off when subjected to vibration or external force, thereby ensuring a firm connection between the components. This is called self-locking snap-fit.

[0046] For example: the matching of grooves and convexities; the matching of buckles and grooves. The edge of a component is designed with outwardly extending barbs. When docking with other components, these barbs can be embedded in the corresponding grooves of the other party to form a self-locking. Another example: using the principle of inclined planes, when the inclined plane on one component is inserted into the straight groove of the other party, it is gradually tightened by sliding. The inclination angle of the inclined plane and the friction force work together to form a self-locking. Another example: interlocking blades or teeth achieve self-locking through the mutual engagement of a series of latch teeth. The shape and arrangement of the latch teeth determine the stability of the self-locking.

[0047] The technical solution of the present invention is to provide a positioning portion 160 with a self-locking clamping structure on the gas-liquid separator 100, which cooperates with the limiting portion 220 of the mounting bracket 200; thereby, after the gas-liquid separator 100 is fixed on the mounting bracket 200, the gas-liquid separator 100 can be limited by the positioning portion 160 and the limiting portion 220, without the need for additional fasteners, thereby simplifying the assembly process; reducing the risk of failure caused by loose fasteners, improving the stability of the product and the reliability of long-term use, and allowing quick disassembly and reuse, thereby improving flexibility; and the self-locking design often makes the product structure more compact, which helps to achieve miniaturization and lightweight of the product, and is particularly suitable for application scenarios with limited space or weight sensitivity.

[0048] See also Figure 3 and Figure 5 In order to facilitate manufacturing and ensure reliability of the clamping, the positioning portion 160 is configured as a positioning groove 161. In one embodiment, the positioning groove 161 is provided on the lower cover 130; in other embodiments, the positioning groove 161 is provided on the upper cover 110 and the lower cover 130, or is provided on the upper cover 110. The corresponding limiting portion 220 that cooperates with the positioning groove 161 is configured as a component that can be provided in the positioning groove 161. When the positioning groove 161 is arranged on the lower cover 130, the limiting portion 220 of the mounting bracket 200 can also play a supporting role, so that when the gas-liquid separator 100 is installed, it can play a pre-positioning role, which is convenient for assembly. Taking the positioning groove 161 provided on the lower cover 130 as an example, for the convenience of installation, the positioning groove 161 has an open mouth 163, and the open mouth 163 is connected to the edge of the lower cover 130. The setting of the open mouth 163 makes it easier for the limiting portion 220 to be inserted into the positioning groove 161 during assembly, thereby simplifying the assembly process; without affecting the structural strength, the open mouth 163 can reduce the use of materials, thereby reducing the weight of the entire assembly.

[0049] The positioning groove 161 on the gas-liquid separator 100 can be cast as one piece with the gas-liquid separator 100; the end face of the positioning groove 161 can also be machined separately on the upper cover 110 or the lower cover 130, such as by injection molding, or turning molding, or stamping molding, or die-casting molding, and then brazed with the tank body 120.

[0050] In order to ensure a secure fit between the positioning groove 161 and the limiting portion 220 , the groove depth of the positioning groove 161 is 3 mm-5 mm; for example, 3 mm, 3.5 mm, 4 mm, 4.5 mm, etc.

[0051] The diameter of the positioning groove 161 gradually decreases from the open mouth 163 to the groove bottom wall direction of the positioning groove 161. The diameter of the open mouth 163 of the positioning groove 161 is larger than the diameter of the groove bottom of the positioning groove 161, that is, it is gradually set to form a shape similar to a funnel. The shape of the positioning groove 161 is half-moon, square, round, horseshoe, or pear; in this way, the limiting portion 220 matched with the positioning groove 161 is a structure with a smaller head and a larger tail. Due to the smaller head, the limiting portion 220 (such as the bottom of the L-shaped bracket) only needs to apply a smaller force during assembly to push the limiting portion 220 into the positioning groove 161, which simplifies the assembly process. The design of a smaller head reduces the friction resistance during insertion, while the design of a larger tail ensures correct positioning and fixation. The design of a larger tail increases the contact area between the limiting portion 220 and the bottom of the positioning groove 161, thereby improving the stability and anti-pull-off ability of the connection. This design can effectively prevent the limit portion 220 from accidentally falling off during use without using an additional locking mechanism; in addition, the larger tail design can increase the contact area between the limit portion 220 and the positioning groove 161, thereby dispersing stress and improving the overall structural strength and durability.

[0052] After the gas-liquid separator 100 is fixed on the mounting bracket 200, the refrigerant pipeline needs to be assembled finally. The assembly of the refrigerant pipeline requires connecting the gas-liquid separator 100 as well as components such as the compressor, and the pipeline wiring process needs to be fixed, which makes the assembly complicated. For this reason, the utility model also provides a gas-liquid separator 100, and the basic structure of the gas-liquid separator 100 is as described above. Specifically, the gas-liquid separator 100 also includes a refrigerant pipe fitting 400. In one embodiment, the refrigerant pipe fitting 400 is brazed into one with the inlet 140; in one embodiment, the refrigerant pipe fitting 400 is brazed into one with the outlet 150; in one embodiment, the refrigerant pipe fitting 400 is brazed into one with the inlet 140 and the outlet 150.

[0053] In order to reduce the number of assembly steps, one end of the refrigerant pipe 400 which does not affect the assembly is integrated with the gas-liquid separator 100 by brazing, and the other end of the refrigerant pipe 400 is provided with a pressure plate 500 which is installed in conjunction with the front-end module or other components. The pressure plate 500 and the refrigerant pipe 400 are brazed together and fixed with nuts through bolts on the pressure plate 500 during assembly.

[0054] In other embodiments, the refrigerant pipe 400 may also be brazed on the inlet 140 and the outlet 150 of the gas-liquid separator 100 having the positioning portion 160 .

[0055] See also Figure 6 and Figure 7, the following introduces the mounting bracket 200 for fixing the gas-liquid separator 100. The mounting bracket 200 can be arranged at the compressor of the air-conditioning system close to the vehicle body. The mounting bracket 200 can be sold separately; the mounting bracket 200 can also be matched with the above-mentioned gas-liquid separator 100 to form a gas-liquid separator 100 assembly for sale. Specifically, in one embodiment, the mounting bracket 200 includes a main body section 211 and a bending section 213 connected to the main body section 211, the limiting portion 220 is configured as the bending section 213, the positioning portion 160 is configured as a positioning groove 161, and the bending section 213 is placed in the positioning groove 161. For the convenience of installation, the bending section 213 and the positioning groove 161 are gap-matched at the edge.

[0056] See also Figure 6 , Figure 7 and Figure 8 In one embodiment, the mounting bracket 200 is formed into a C shape, and is clamped and fixed to the gas-liquid separator 100; Figure 6 In another embodiment, the mounting bracket 200 cooperates with the auxiliary bracket 600 to fix the gas-liquid separator 100 .

[0057] See also Figure 7 Under the premise of ensuring structural strength, in order to save costs, the mounting bracket 200 and the heat dissipation shell are injection molded as one, and at least part of the space between the bottom of the mounting bracket 200 and the outer side of the shell is provided with a cavity. The mounting bracket 200 and the heat dissipation shell are injection molded as one, and the one-piece molding design can simplify the production process, reduce assembly steps, and improve production efficiency. The cavity is set at an appropriate position, and the size and shape of the cavity design can be adjusted as needed, which can reduce weight, improve heat dissipation efficiency and assembly efficiency while ensuring structural strength. The cavity here can be a gap or opening that passes through the mounting bracket 200 and the heat dissipation shell, or it can be a hollow state in the middle, but a closed structure on the outside, such as a hollow base surrounding the mounting bracket 200.

[0058] See also Figure 7 and Figure 8 In order to provide structural strength for the mounting bracket 200, reinforcing ribs 230 are provided on the bending section 213 and the main section 211; the middle of the bending section 213 is recessed downward to form the reinforcing rib 230; in addition, in order to ensure stable fixation, the thickness of the portion where the main section 211 is fixed to the auxiliary bracket 600 is greater than the thickness of other portions.

[0059] In other embodiments, the gas-liquid separator 100 assembly also includes an auxiliary bracket 600, which cooperates with the mounting bracket 200 to clamp and fix the gas-liquid separator 100, and the positioning portion 160 is configured as a positioning pin 164, which is provided on the outer wall of the tank body 120; the limiting portion 220 is configured as a positioning hole, which is arranged on the auxiliary bracket 600, and the auxiliary bracket 600 and the mounting bracket 200 can be an integral structure, and an installation port for inserting the gas-liquid separator 100 is formed between the auxiliary bracket 600 and the mounting bracket 200, and the outer wall of the gas-liquid separator 100 and the installation port are interference fit.

[0060] See also Figure 7 The mounting bracket 200 includes a main frame body 210, the main frame body 210 includes a main section 211 and two fixing sections 212 disposed at both ends of the main section 211, and the bending section 213 is disposed at the end of the main section 211 and is located below the two fixing sections 212. Figure 8 The auxiliary bracket 600 includes a main body section 610 and two mounting sections 620 disposed at both ends of the main body section 610. A mounting section 620 is connected to a fixed section 212. In one embodiment, the main body section 211 is arranged in an arc shape; in one embodiment, the main body section 211 and the main body section 610 are both arranged in an arc shape; in one embodiment, the main body section 610 is arranged in an arc shape to adapt to the outer periphery of the gas-liquid separator 100. A metal bracket is used, and an arc-shaped structure is adopted in the middle to cooperate with the cylinder of the gas-liquid separator 100. The gas-liquid separator 100 usually has a non-planar profile, especially when considering that it accommodates the refrigerant flow path and other functional structures. By designing the main body section 211 and the main body section 610 in an arc shape, the bracket can better fit the curved surface shape of the gas-liquid separator 100, thereby providing a tighter and more stable support. The arc design can make more efficient use of three-dimensional space, especially in a space-constrained environment such as the front-end module of a vehicle. The arc bracket can better conform to the complex geometry of the front of the vehicle, reduce interference with surrounding components, and optimize the overall layout. The understanding of the arc portion should include but is not limited to a part of a circle or ellipse, or any other continuously curved lines or surfaces, as long as they constitute a non-linear, curvilinear structural part. In actual applications, the most suitable curvature and shape will be selected according to the specific size, installation environment, and mechanical requirements of the gas-liquid separator 100 to achieve the established design goals.

[0061] In other embodiments, in order to reduce the complexity of the assembly process, the mounting bracket 200 is integrated on the front bracket 310, which can solve the problems of a large variety of parts, high development / maintenance costs, low assembly efficiency and insufficient stability.

[0062] See also Figure 6Specifically, the front-end module assembly 300 includes a front-end bracket 310, a heat dissipation system integrated in the front-end bracket 310, and the above-mentioned gas-liquid separator 100. The mounting bracket 200 is integrated with the front-end bracket 310; the gas-liquid separator 100 is connected to the heat dissipation system pipeline. The front-end module assembly 300 (FEM for short) is a system that integrates the front-end components of the vehicle. It integrates components such as cabin locks, radiators, condensers, intercoolers, anti-collision beams, buffer blocks, sensors, headlights, bumpers and even fenders. I will not go into details here.

[0063] Because the mounting bracket 200 is integrated with the front end bracket 310, there is no need to assemble the mounting bracket 200 separately during assembly, and the installation is faster. The mounting bracket 200 and the front end bracket 310 form a unified whole, which not only improves the stability and durability of the structure; in addition, there is no need to weld the mounting bracket 200 on the gas-liquid separator 100, which can also reduce the weight of the gas-liquid separator 100.

[0064] The utility model also provides a vehicle, which includes a vehicle body and a front-end module assembly 300. The specific structure of the front-end module assembly 300 refers to the above-mentioned embodiment. Since the vehicle adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. Among them, the front-end module assembly 300 is arranged on the vehicle body.

[0065] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
