[0026] The battery box connecting bracket 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0027] like Figures 1-5As shown, the battery box connecting bracket 1 according to the embodiment of the present utility model is constructed in the shape of "I" and includes: an upper mounting part 100, a lower mounting part 200 and a connecting part 300.

[0028] The upper mounting portion 100 extends horizontally, with both ends adapted to be mounted to the frame 10 by fasteners, and the middle portion adapted to be mounted to the upper part of the battery box 20. The lower mounting portion 200 extends horizontally and is located below the upper mounting portion 100, with both ends adapted to be mounted to the frame 10 by fasteners, and the middle portion adapted to be mounted to the lower part of the battery box 20. A connecting portion 300 connects the upper mounting portion 100 and the lower mounting portion 200.

[0029] For example, the battery box connecting bracket 1 is integrally cast and is connected to the side of the battery box 20 facing the frame 10. The height of the battery box connecting bracket 1 is equal to the height of the battery box 20. The fasteners that pass through both ends of the upper mounting part 100 and both ends of the lower mounting part 200 are bolts. The inner side of the battery box connecting bracket 1 is attached to the longitudinal beam of the frame 10, and the outer side of the battery box connecting bracket 1 is attached to the battery box 20.

[0030] According to an embodiment of this utility model, the battery box connecting bracket 1 is constructed in an "I" shape. Further, the upper mounting portion 100 is connected to the upper edge of the battery box 20, and the lower mounting portion 200 is flush with the lower edge of the battery box 20, making the shape of the battery box connecting bracket 1 conform to the shape of the battery box 20, thereby providing fixing points for the frame 10 at the upper and lower edges of the battery box 20. The frame 10 is connected through four mounting holes in the upper mounting portion 100 and the lower mounting portion 200, forming a large mounting area and a relatively firm connection with the frame 10. The battery box 20 is connected through two mounting holes in the middle of the upper mounting portion 100 and the middle of the lower mounting portion 200. This provides a relatively firm fixing function for both the frame 10 and the battery box 20. Furthermore, the "I"-shaped battery box connecting bracket 1 uses less material between the upper mounting portion 100 and the lower mounting portion 200, achieving the advantage of lightweight while ensuring structural strength.

[0031] Therefore, the battery box connecting bracket 1 according to the present utility model has the advantages of high structural strength, large force-bearing area, and stable force.

[0032] In some specific embodiments of this utility model, such as Figure 3 As shown, both ends of the upper mounting portion 100 and both ends of the lower mounting portion 200 are provided with frame support columns 400 protruding toward the frame 10. The frame support columns 400 are adapted to be fitted with fasteners to be fixed to the frame 10.

[0033] By constructing the frame support column 400, support points for the frame 10 are formed at the four corners of the "I" shape. The frame support column 400 better supports the fasteners, thereby increasing the preload of the connection between the battery box connecting bracket 1 and the frame 10, and making the fastening of the battery box connecting bracket 1 and the frame 10 more secure.

[0034] In some specific embodiments of this utility model, such as Figure 2 As shown, both the middle of the upper mounting portion 100 and the middle of the lower mounting portion 200 are provided with battery box support columns 500 that protrude in the direction away from the frame 10. The battery box support columns 500 are suitable for fasteners to be inserted and fixed to the battery box.

[0035] By constructing the battery box support column 500, a support point for the battery box 20 is formed in the middle of the "I" shape. The frame support column 400 better supports the fasteners, thereby increasing the pre-tightening force between the battery box connecting bracket 1 and the battery box, and making the fastening between the battery box connecting bracket 1 and the frame 10 more secure.

[0036] In some specific embodiments of this utility model, such as Figure 3 As shown, the middle part of the upper mounting part 100 and the middle part of the lower mounting part 200 are provided with receiving grooves 101 on the side facing the frame 10.

[0037] The receiving groove 101 serves two purposes: firstly, it accommodates the fasteners that secure the battery box 20. Bolts securing the battery box 20 pass through the receiving groove 101 from one side outwards into the battery box 20, thus allowing the bolts fixed to the battery box 20 to be accommodated within the receiving groove 101. Furthermore, the receiving groove 101 secures the fasteners that fix the battery box. Secondly, the receiving groove reduces the amount of material used in the battery box connection structure 1, thereby reducing weight.

[0038] Furthermore, such as Figure 3 As shown, the receiving groove 101 of the upper mounting portion 100 and the receiving groove 101 of the lower mounting portion 200 are connected at the connecting portion 300 to avoid the fasteners of the frame 10.

[0039] For example, the receiving groove 101 is an integral long rectangular groove, so that the receiving groove 101 of the upper mounting part 100 and the receiving groove of the lower mounting part 200 are connected to form an integral groove structure. A space is formed between the receiving groove 101 of the upper mounting part 100 and the receiving groove 101 of the lower mounting part 200 to accommodate bolts on the frame 10, further reducing the amount of material used in the battery box connection structure 1, thereby reducing weight.

[0040] In some specific embodiments of this utility model, such as Figure 4As shown, the receiving groove 101 is constructed with a limiting ridge 102 that matches the profile of the fastener. For example, the limiting ridge 102 forms a hexagonal inner profile within the receiving groove 101. The nut or bolt is received within the receiving groove 101 and limited by the limiting ridge 102, thereby preventing the fastener from rotating and concealing the fastener that secures the battery box 20 within the receiving groove 101.

[0041] In some specific embodiments of this utility model, such as Figure 4 As shown, the edges at both ends of the upper mounting portion 100 are constructed in an arc shape; the edges at both ends of the lower mounting portion 200 are constructed in an arc shape.

[0042] The arcs at the edges of the upper mounting portion 100 and the lower mounting portion 200 coincide with the center of the mounting hole. Furthermore, the outer contour of the frame support column 400 is identical in shape to the edge contour of the upper mounting portion 100. The frame support column 400 utilizes the space between the upper mounting portion 100 and the lower mounting portion 200 to the maximum extent. In some specific embodiments of this invention, the upper mounting portion 100 and the lower mounting portion 200 are symmetrical in the vertical direction. The upper and lower portions of the battery box connecting bracket 1 experience equal forces, resulting in more uniform force distribution.

[0043] In some specific embodiments of this utility model, the battery box connecting bracket 1 is integrally formed. Because the battery box connecting bracket 1 is formed as a single piece, no further processing is required, the material has high integrity, the forming process is convenient, and no additional connections such as welding are needed, resulting in a robust structure.

[0044] The following describes the battery box assembly 2 according to an embodiment of the present invention.

[0045] According to an embodiment of the present invention, the battery box assembly 2 includes: a battery box and a plurality of battery box connecting brackets 1 according to the above embodiment of the present invention, wherein the battery box connecting brackets 1 are installed between the battery box 20 and the vehicle frame 10.
