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 an automotive battery cooler mounting plate structure. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source or use conventional vehicle fuels with new on-board power devices, integrating advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. In new energy vehicle models, the power steering system is mostly an electric power steering system (EPS), which has advantages such as energy saving and environmental protection, but provides relatively little assistance and cannot meet the power steering requirements of large buses. With the rapid development of new energy vehicles, the production capacity of battery coolers is also gradually increasing. To meet order delivery needs, in addition to investment in production lines, the design needs to consider platformization and structural optimization to facilitate component processing and improve component production efficiency. At the same time, the produced battery coolers should have a clean and aesthetically pleasing appearance.

[0003] The existing automotive battery cooler mounting plate has three countersunk holes that are not fully drilled, and lacks a material removal hole design. From a parts processing perspective, this design requires additional machining of the three positioning holes besides blanking and punching, adding an extra step, reducing production efficiency, and increasing parts costs. From a product manufacturing perspective, although it effectively prevents solder from flowing onto the surface of the brazing backing plate, the mounting plate and the brazing backing plate are almost completely in contact, requiring extra control over the surface cleanliness of the brazing backing plate. Otherwise, the bottom surface of the product will have an unsightly appearance after brazing, requiring further treatment. In conventional structures, to ensure surface cleanliness after brazing, a layer of clean aluminum foil is often placed between the mounting plate and the brazing backing plate to prevent dirt from the surface of the brazing backing plate from entering the product. The overall process and structure are quite complex. Therefore, a new automotive battery cooler mounting plate structure is needed to solve the above problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a mounting plate structure for an automotive battery cooler, comprising a base plate and a mounting plate. A brazed backing plate is provided below the mounting plate to assist in positioning and connecting the base plate and the mounting plate. Three base plate protrusions are provided in the middle of the base plate, and mounting plate positioning holes are provided at the corresponding positions of the three base plate protrusions. Several material flow through holes are provided above and below the positioning holes of the mounting plate.

[0005] A further improvement of this utility model is that: four reinforcing protrusions are provided on the end face of the base plate near the edge.

[0006] A further improvement of this utility model is that the bottom surface of the reinforcing protrusion structure is an arc-shaped structure, which is used to enhance the overall firmness of the base plate and prevent deformation due to excessive impact when connected to the mounting plate.

[0007] A further improvement of this utility model is that the height of the reinforcing protrusion is half the height of the base plate.

[0008] A further improvement of this utility model is that the diameter of the bottom plate positioning protrusion structure is smaller than the diameter of the mounting plate positioning hole.

[0009] A further improvement of this utility model is that the length of the base plate positioning protrusion structure is less than the depth of the mounting plate positioning hole.

[0010] The structural design of the mounting plate of this utility model, with the flow through hole, can effectively prevent solder from flowing onto the surface of the brazing backing plate. At the same time, since the solder can be absorbed by the side wall of the flow through hole, the mounting plate and the brazing backing plate will not stick together, and the surface cleanliness of the brazing backing plate will not require special control. The bottom appearance of the product after brazing meets the requirements, and there is no need to place a clean aluminum foil between the mounting plate and the brazing backing plate to ensure the surface cleanliness after brazing. The overall process and structure are relatively simple, which improves the production efficiency of parts, and the aluminum foil can be eliminated without affecting the appearance. At the same time, the appearance of the mounting plate after brazing is also improved. Attached Figure Description

[0017] 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.

[0018] This utility model relates to a mounting plate structure for an automotive battery cooler, including a base plate 1 and a mounting plate 2. A brazing backing plate 3 is provided below the mounting plate 2. The brazing backing plate 3 is used to assist in the positioning and connection of the base plate 1 and the mounting plate 2. Three base plate protrusions 4 are provided in the middle of the base plate 1. The mounting plate 2 is provided with mounting plate positioning holes 5 corresponding to the three base plate protrusions 4. Several material flow through holes 6 are provided above and below the mounting plate positioning holes 5. The battery cooler needs to be brazed in a furnace. The solder layer 4045 on the surface of the base plate 1 melts and flows at high temperature to weld together with the mounting plate 2. The brazing backing plate 3 is only an auxiliary tooling and needs to be removed after brazing.

[0019] The base plate 1 has four reinforcing protrusions 7 near the edge of its end face. The bottom surface of each reinforcing protrusion 7 is an arc-shaped structure 8, which enhances the overall rigidity of the base plate 1 and prevents deformation due to excessive impact when connected to the mounting plate 2. The height of each reinforcing protrusion 7 is half the height of the base plate 1, resulting in better overall structural strength. The diameter of the base plate positioning protrusion 4 is smaller than the diameter of the mounting plate positioning hole 5, allowing for a more stable engagement between the mounting plate 2 and the base plate 1. The length of the base plate positioning protrusion 4 is less than the depth of the mounting plate positioning hole 5.

[0020] The optimized design of the mounting plate structure involves opening the positioning holes 5 of the mounting plate and designing several material flow through holes 6. From the perspective of component processing, this design facilitates processing, requiring only blanking and punching processes, and has high production efficiency. From the perspective of product manufacturing, this design can prevent adhesion and poor cleanliness between the brazing backing plate 3 and the mounting plate 2.

[0021] The original structure is shown below. Figure 2 By using the three positioning holes as countersunk holes and not drilling them through, the material removal function cannot be realized. Furthermore, from the perspective of component processing, this design requires the separate machining of the three mounting plate positioning holes 5, adding an extra process, reducing production efficiency and increasing component costs. From the perspective of product manufacturing, although it effectively prevents solder from flowing to the surface of the brazing backing plate 3, the mounting plate 2 and the brazing backing plate 3 are almost completely attached, which means that the surface cleanliness of the brazing backing plate 3 needs to be carefully controlled. Otherwise, the bottom surface of the product will have a poor appearance after brazing, requiring additional processing, which is time-consuming and labor-intensive.

[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.
