Description

A mounting panel and mounting structure for an aluminum alloy die-cast connector suitable for welding processes Technical Field

[0001] This utility model relates to the field of automotive battery tray bracket technology, specifically to an aluminum alloy die-cast connector mounting panel and mounting structure suitable for welding processes. Background Technology

[0002] A battery tray is a device used to store, secure, or transport batteries. It is widely used in the electric vehicle industry and is a key component of the battery pack, requiring high strength, lightweight design, and collision safety.

[0003] The connector mounting panel on the battery tray is a key component of the battery system. It provides stable and rigid support for the battery connectors, preventing them from loosening due to vehicle vibration or impact and ensuring long-term reliability. In addition, the connector mounting panel can also provide a unified electrical connection point for battery modules, battery management systems, sensors, etc., and simplify the wiring structure.

[0004] In existing technologies, connector mounting panels are fixed to the battery tray frame via riveting. While riveting secures the connector mounting panel to the battery tray, the sealing and strength of this structure remain somewhat insufficient. Therefore, some connector mounting panel manufacturers use welding to fix the panel to the battery tray. Although welding improves the mounting strength, current methods simply involve placing the panel vertically onto the battery tray frame and welding directly. This results in a vertical weld, which is prone to defects and a less secure connection. Summary of the Invention

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide an aluminum alloy die-cast connector mounting panel and mounting structure suitable for welding process, so as to solve the problem of the weak mounting welding structure of the connector mounting panel on the existing battery tray.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] In a first aspect, this application provides an aluminum alloy die-cast connector mounting panel suitable for welding processes, including a top panel, a front panel, a rear panel, and a pair of side panels. The top panel has mounting holes for mounting connectors on its end face. The pair of side panels extend obliquely downward from the top of the top panel from the left and right sides respectively. The pair of side panels have the same downward inclination angle. A positioning part is provided at the bottom of the side panels. The pair of side panels and the top panel form an external structure with a longitudinal cross-section approximately in the shape of an "eight". The top panel, front panel, rear panel, and pair of side panels are die-cast.

[0008] Furthermore, the positioning part is a stepped notch formed at the bottom end of the side panel near the rear panel.

[0009] Furthermore, an upwardly extending mounting plate is provided on the outer wall of the rear panel, and a connection hole is provided at the top of the mounting plate.

[0010] Furthermore, the inner side of the mounting plate is parallel to the front panel.

[0011] Furthermore, reinforcing ribs are provided between the top of the inner wall of the front panel, the rear panel, and the pair of side panels and the bottom surface of the top panel.

[0012] Furthermore, the top panel, front panel, rear panel, and a pair of side panels are made of AiSi10MnMg material.

[0013] Secondly, this application also provides an installation structure for an aluminum alloy die-cast connector mounting panel suitable for welding processes, including an aluminum alloy frame and an aluminum alloy die-cast connector mounting panel suitable for welding processes as described above. A notch is provided on one side of the upper end face of the aluminum alloy frame. The bottom end of the rear panel and the positioning portions on a pair of side panels are mounted on the upper end face of the aluminum alloy frame. The outer edge portions of the positioning portions on the pair of side panels are attached to the inner end faces of the left and right sides of the notch.

[0014] The beneficial effects of this utility model are as follows:

[0015] By employing the aforementioned aluminum alloy die-cast connector mounting panel, positioning parts are respectively provided at the bottom ends of a pair of oppositely arranged side panels. When the connector mounting panel is placed on the aluminum alloy frame on the battery tray, the positioning parts enable quick and accurate positioning of the connector mounting panel on the aluminum alloy frame. Furthermore, the pair of side panels have a downward-sloping shape, which creates a bevel between the outer side of the side panel and the aluminum alloy frame during welding. This results in a longer beveled weld, which improves the connection strength between the connector mounting panel and the aluminum alloy frame. Additionally, the weld exerts a downward pull on the side panel along the inclined direction of the side panel. This downward pull can be decomposed into a horizontal wedging force on the aluminum alloy frame and a vertical downward pressure, further ensuring the connection strength between the beveled panel and the aluminum alloy frame.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] Referring to Figures 1 to 3, this embodiment provides an aluminum alloy die-cast connector mounting panel 100 suitable for welding processes, including a top panel 10, a front panel 30, a rear panel 20, and a pair of side panels 40. The top panel 10 has a plurality of mounting holes 11 for fixing the connector to the top panel 10.

[0036] Referring to Figure 1, a pair of side panels 40 extend diagonally downwards from the top of the top panel 10 from the left and right sides respectively. The pair of side panels 40 tilt downwards at the same angle. A positioning part 41 is provided at the bottom end of the side panel 40 near the rear panel 20. The positioning part 41 is used to position the connector mounting panel when it is welded and installed on the aluminum alloy frame. Specifically, in this embodiment, the positioning part 41 on the side panel 40 is a stepped notch formed at the bottom end of the side panel 40 near the rear panel 20. When the side panel 40 is installed on the aluminum alloy frame, the stepped notch on the side panel 40 matches the aluminum alloy frame (the structure of the aluminum alloy frame will be described below), thus enabling the side panel 40 to be quickly and accurately installed on the top surface of the aluminum alloy frame. A pair of side panels 40 and the top panel 10 form an approximately "V"-shaped structure in longitudinal section. Specifically, the side panels 40 gradually expand outwards from their top to bottom. This design allows for a beveled shape between the side panels 40 and the aluminum alloy frame, facilitating welding. In this embodiment, the top panel 10, front panel 30, rear panel 20, and pair of side panels 40 are die-cast. Die-casting allows for the creation of more complex shapes.

[0037] By adopting the above-described aluminum alloy die-cast connector mounting panel, since the connector mounting panel is an integrally formed structure, when it is installed on the aluminum alloy frame, the bottom end of the rear panel 20 and the positioning parts 41 of the pair of side panels 40 are respectively placed on the top surface of the aluminum alloy frame. The positioning parts 41 can quickly and accurately achieve the positioning and placement of the connector mounting panel on the aluminum alloy frame. After the connector mounting panel is placed in place, the joint between the connector mounting panel and the aluminum alloy frame is welded. A bevel is formed between the outer side of the side panel 40 and the aluminum alloy frame. The beveled weld formed after welding is longer, which is beneficial to improving the connection strength between the connector mounting panel and the aluminum alloy frame. Moreover, after welding, the weld forms a downward pull force on the side panel along the inclined direction of the side panel. This downward pull force can be decomposed into a horizontal wedging force on the aluminum alloy frame and a vertical downward pressure, which can better ensure the connection strength between the beveled panel and the aluminum alloy frame.

[0038] In some embodiments, the top panel, front panel, rear panel, and a pair of side panels are made of AiSi10MnMg material to allow for better direct welding to the battery aluminum alloy frame and to better meet the requirements of the penetration test.

[0039] Referring to Figures 1 and 3, in this embodiment, an upwardly extending mounting plate 50 is also provided on the outer wall of the rear panel 20. A connection hole 51 is provided at the top of the mounting plate 50, and the inner side of the mounting plate 50 is parallel to the front panel 30.

[0040] Referring to Figure 2, in this embodiment, to improve the overall strength of the aluminum alloy die-cast connector mounting panel, reinforcing ribs 60 are provided between the top of the inner walls of the front panel 30, the rear panel 20, and a pair of side panels 40 and the bottom surface of the top panel 10, respectively. Furthermore, the reinforcing ribs 60 prevent stress concentration in the weld seam, thus avoiding excessive stress, and distribute the load to prevent component deformation.

[0041] Referring to Figures 4 to 7, in this embodiment, an aluminum alloy die-cast connector mounting panel mounting structure 300 suitable for welding process is also provided. It includes an aluminum alloy frame 200 and an aluminum alloy die-cast connector mounting panel 100. A notch 70 is provided on the outer side of the upper end face of the aluminum alloy frame 200. The bottom end of the rear panel 20 and the positioning part 41 on the pair of side panels 40 are installed on the upper end face of the aluminum alloy frame 200. That is, the bottom end of the rear panel 20 and the positioning part 41 of the side panels 40 are placed on the upper end face of the aluminum alloy frame 200 at the inner side of the notch 70 (as shown in Figures 5 and 6). The stepped notch exactly matches the part of the aluminum alloy frame 200 retained on the upper end face of the aluminum alloy frame 200 (the inner end face of the notch 70 on the upper end face of the aluminum alloy frame 200). The outer edge part 42 of the pair of side panels 40 located on the positioning part 41 is attached to the inner end face of the left and right sides of the notch 70.

[0042] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
