[0024] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 4As shown, a new energy battery frame of the utility model includes a frame 1, and a bracket 2 for supporting the battery is distributed in the frame 1. The bracket 2 has a mounting hole. After the battery is placed on the bracket 2, it can be fixed on the bracket 2 by passing the bolts through the mounting hole. A mounting plate 4 is also provided at the bottom of the frame 1. The battery frame 1 can be directly mounted on the frame through the mounting plate 4 to complete the fixation of the battery relative to the frame. Specifically, the frame 1 includes two parallel side panels 11, the side panels 11 are vertically arranged to the ground, and panels 12 are fixed on both sides of the side panels 11, respectively. The panels 12 and the side panels 11 are combined into a rectangle, and the battery is placed in the frame 1 composed of the panels 12 and the side panels 11. Among them, a folding plate 121 is bent on both sides of each panel 12 toward the side panel 11, and the folding plate 121 is welded and fixed to the corresponding side panel 11, and the mounting plate 4 is welded to the lower end of the frame 1. The folded plate 121 of the panel 12 is welded to the corresponding side plate 11, so that the entire frame 1 can be bent and welded through a piece of steel plate, so that the frame 1 can be quickly installed and formed, saving time, and the welded frame 1 has a simple structure and high strength.

[0026] A support frame 9 is also provided at the top of the frame 1, and the support frame 9 is X-shaped. The X-shaped support frame 9 can increase the connection stability between the panel 12 and the side panel 11, prevent the frame 1 from being deformed, and a hoisting plate is provided at the four corners of the top of the frame 1. The frame 1 with the battery installed can be hoisted onto the vehicle frame by connecting the hoisting plate with a crane.

[0027] To facilitate the positioning of the folding plate 121 and the side plate 11 for welding, welding holes 10 are spaced apart on the folding plate 121. When welding the side plate 11 and the folding plate 121, the folding plate 121 and the side plate 11 are first aligned, and then the welding holes 10 on the folding plate 121 are plug welded, and then the folding plate 121 and the side plate 11 are welded by the plate edge segment method. The operation is simple and the assembly is convenient.

[0028] Preferably, through holes 6 are spaced apart on the panel 12 and the side panels 11, and the through holes 6 on the panel 12 are arranged at positions corresponding to the through holes 6 on the side panels 11. The battery can be installed on the bracket 2 through the through holes 6, so as to facilitate the disassembly and assembly of the battery on the frame 1. It should be noted that a first step plate 111 is formed between adjacent through holes 6 on the side panels 11, a second step plate 5 is formed between adjacent through holes 6 on the panel 12, and a plurality of brackets 2 are distributed on each second step plate 5. The provision of a plurality of brackets 2 reduces the load-bearing capacity of the battery on a single bracket 2, increases the service life of the bracket 2, and improves the practicality of the battery frame. Figure 1 and Figure 2As shown, a reinforcing beam 3 is welded to the inner wall of the second step plate 5, and the bracket 2 and its corresponding reinforcing beam 3 are welded. The reinforcing beam 3 can not only increase the rigidity of the overall frame 1, but also prevent the panel 12 of the frame 1 from being deformed when the vehicle is hit and stopped suddenly.

[0029] As another preferred embodiment, a card slot 7 is provided at both ends of the bracket 2, and the card slot 7 is engaged with the corresponding reinforcing beam 3. After the card slot 7 is engaged with the corresponding reinforcing beam 3, the welding length of the reinforcing beam 3 and the bracket 2 can be increased, and the connection strength of the reinforcing beam 3 and the bracket 2 can be increased. The combined reinforcing beam 3, bracket 2 and frame 1 can greatly improve the load-bearing strength of the new energy battery frame. In order to facilitate the fixing of the position of the bracket 2 relative to the panel 12, as shown in FIG. Figure 3 As shown, extension blocks 8 protrude outward at both ends of the bracket 2, and positioning grooves 51 are opened on the second step plate 5, and the extension blocks 8 can be stuck in the positioning grooves 51. When the extension blocks 8 are stuck in the positioning grooves 51, the top surface of the bracket 2 is flush with the top surface of the second step plate 5 connected to it, which can facilitate the installation of the battery on the bracket 2. The extension blocks 8 are stuck in the positioning grooves 51, which can facilitate the rapid positioning of the second step plate 5 of the panel 12 and the bracket 2, saving time and improving production efficiency.

[0030] like Figure 4 As shown, the mounting plate 4 is an L-shaped plate, which is formed by bending and forming an integral body, and two mounting plates 4 are symmetrically arranged around the center of the side plate 11. The two mounting plates 4 can be directly inserted between the two side plates 11 and welded with the two panels 12, so as to achieve the purpose of welding and fixing the mounting plate 4 relative to the upper panel 12 of the frame 1. It should be noted that the folding plate 121 and the mounting plate 4 are formed by a bending process, and their strength is higher than the welding strength of the rectangular tube, and it is not easy to have open welding and fracture, which effectively improves the practicality of the new energy battery frame.

[0031] Installation method: Assemble and weld the panel 12 and the side panel 11, then weld the reinforcing beam 3 to the inner wall of the second step plate 5, and then place the extension plate on the bracket 2 in the corresponding positioning groove 51 on each second step plate 5 to complete the installation of the bracket 2 on the second step plate 5 of the two panels 12. After installation, weld the connecting seams between the second step plate 5, the reinforcing beam 3 and the bracket 2. After welding, place the batteries on the bracket 2 from bottom to top through the through holes 6 of the panel 12, and fix the batteries to the corresponding bracket 2 with bolts. After the battery is installed, the new energy battery frame with the battery installed can be hoisted to the frame for installation through the hoisting plate on the crane hoisting frame 1.
