Description

Technical Field

[0001] This utility model relates to the technical field of automotive cooling systems and is used to manufacture radiator water chambers, specifically a liquid cooling plate riveting bracket anti-rotation positioning structure. Background Technology

[0002] With the booming development of new energy vehicles, the demand for liquid cooling plates is also increasing. Currently, square battery stations account for 94.5% of the new energy vehicle industry. Liquid cooling plates that are used with square batteries generally come in two types: stamped structure and manifold combined with flat tube structure. The manifold combined with flat tube structure liquid cooling plate is composed of manifold assembly plus flat tube. The manifold assembly is composed of multiple parts assembled and fixed together. Due to the large number of parts, the structure is complex. Generally, argon arc welding, laser welding, riveting and other methods are used. Argon arc welding and laser welding have strict requirements for the operator's ability and are prone to phenomena such as breakdown during welding.

[0003] The cumbersome loading and unloading processes affect the operating cycle and become a bottleneck in the entire manufacturing process of liquid cooling plates, resulting in high overall costs. Currently, the most commonly used process in the industry is riveting. Riveting uses rivets to fix two parts together, avoiding the risk of welding breakdown. The process has a fast operating cycle, beautiful appearance, and low cost. Although riveting has many advantages, it has certain disadvantages in terms of positioning. When riveting is used on square manifolds, only the X and Z directions can be fixed with rivets. The Y direction still cannot be positioned, resulting in the bracket rotating around the rivet and failing to achieve final positioning. Therefore, it is necessary to design a liquid cooling plate riveting bracket anti-rotation positioning structure to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a liquid-cooled plate riveting bracket anti-rotation positioning structure, comprising a bracket and a manifold. The bracket has a first rivet hole, and the manifold has a second rivet hole. The bracket is connected to the manifold by rivets. The rivets pass through the first rivet hole and the second rivet hole to connect the bracket and the manifold. The end face of the manifold near the bracket has a circular hole structure, and the end face of the bracket has a square slot structure above the circular hole structure. A barb structure is integrally provided on the square slot structure, and the barb structure passes through the circular hole structure.

[0005] A further improvement of this utility model is that the bracket is provided with a through hole structure, which facilitates the connection of the bracket with other products.

[0006] A further improvement of this utility model is that the size of the circular hole structure is consistent with the size of the first rivet hole and the second rivet hole, to prevent misuse.

[0007] A further improvement of this utility model is that the height of the thorn-picking structure is 1 mm higher than the thickness of the manifold.

[0008] A further improvement of this utility model is that the width of the thorn-picking structure is smaller than the diameter of the circular hole structure.

[0009] A further improvement of this utility model is that the square slot and the round hole structure are misaligned.

[0010] A further improvement of this utility model is that the longitudinal section of the bracket has a Z-shaped structure.

[0011] This utility model features a novel structure designed for the bracket and the manifold. The first rivet hole of the bracket corresponds to the second rivet hole of the manifold. The barbed structure of the bracket is inserted into the circular hole structure on the manifold. The rivet passes through both the first and second rivet holes. The relative position between the bracket and the manifold is unique and will not change or rotate. The manifold and the bracket are fixedly connected together, achieving self-positioning riveting, which also allows for self-positioning in the Y direction. This structure achieves self-positioning without increasing costs, thus fixing the X, Y, and Z directions, ultimately ensuring the installation dimensions of the liquid cooling plate bracket and meeting customer requirements.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] This utility model provides a self-rotation prevention and positioning structure for a liquid-cooled plate riveting bracket, including a bracket 1 and a manifold 2. The bracket 1 has a first rivet hole 3, and the manifold 2 has a second rivet hole 4. The bracket 1 is connected to the manifold 2 by a rivet 5. The rivet 5 passes through the first rivet hole 3 and the second rivet hole 4 to connect the bracket 1 and the manifold 2. The end face of the manifold 2 near the bracket 1 has a circular hole structure 6. The end face of the bracket 1 above the circular hole structure 6 has a square slot structure 7. A barb structure 8 is integrally provided on the square slot 7. The barb structure 8 passes through the circular hole structure 6. The barb structure 8 can play a limiting role and prevent the bracket 1 from moving left and right on the manifold 2.

[0020] The bracket 1 is provided with a through hole structure 9, which is provided to install the structure of this utility model with other components. An anti-slip pad structure 10 is provided on the inner side of the through hole structure 9, which can help restrict the movement of the bracket 1 and increase stability. The size of the circular hole structure 6 is the same as the size of the first rivet hole 3 and the second rivet hole 4. The height of the barbed structure 8 is 1 mm higher than the thickness of the manifold 2. The width of the barbed structure 8 is smaller than the diameter of the circular hole structure 6. The square slot structure 7 and the circular hole structure 6 are staggered to facilitate the barbed structure 8 to penetrate the circular hole structure 9 for limiting. The longitudinal section of the bracket 1 has a Z-shaped structure.

[0021] After the first rivet hole 3 of the bracket 1 and the second rivet hole 4 of the manifold 2 are aligned, the serrated structure 8 of the bracket 1 can be inserted into the round hole structure 6 on the manifold 2. Finally, the rivet 5 is installed. At this time, the relative position between the bracket 1 and the manifold 2 is unique and will not change or rotate. Finally, the rivet 5 is riveted. After the rivet is installed, the upper and lower ends of the rivet 5 are subjected to force to fix the rivet 5 and ensure that the rivet 5 will not fall off. The manifold 2 and the bracket 1 are fixedly connected together, realizing self-positioning riveting.

[0022] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
