Furthermore, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Currently, commercially available rear battery packs are welded and solidified as a single unit, typically measuring 2460mm in length, 850mm in width, and 2300mm in height. Their large size and weight lead to the following difficulties: 1. Surface treatment is relatively difficult, especially since the electric pool volume needs to be relatively large to meet the process requirements.

[0018] 2. Storage of semi-finished and finished products requires a large area.

[0019] 3. Moving materials within the workshop is cumbersome.

[0020] 4. The transportation costs for semi-finished and finished products are very high. Because the entire assembly needs to be done as a single unit, the requirements for overall assembly and welding are high, as are the requirements for tooling and welding.

[0021] In view of the above problems, a detachable back-mounted battery frame was designed. The design concept is as follows: 1. The strength of the battery frame must be ensured.

[0022] 2. The battery frame can be disassembled into four large sections, making electrophoresis, handling, and transportation convenient.

[0023] 3. Welding large sections separately reduces the requirements for overall welding.

[0024] 4. Segmented and packaged storage solves the problem of having too much storage space.

[0025] This utility model provides a detachable rear battery frame.

[0026] Please see Figures 1-4 The detachable rear battery frame provided by this utility model includes a base 1, which has an upper end in the height direction; a main bracket 2, which is detachably disposed at the upper end of the base 1 in the height direction; a connecting frame 3, which is disposed at the end of the main bracket 2 away from the base 1 and is detachably connected to the main bracket 2, and the base 1, the main bracket 2 and the connecting frame 3 together form an accommodating area; and a mounting frame 4, which is disposed within the accommodating area and is detachably connected to the main bracket 2, and the mounting frame 4 divides the accommodating area into several mounting areas.

[0027] In this invention, the base 1, main support 2, connecting frame 3, and mounting frame 4 can be assembled to form a complete battery frame for battery installation. During production, square tubes can be welded sequentially to form the base 1, main support 2, connecting frame 3, and mounting frame 4. After welding, the base 1, main support 2, connecting frame 3, and mounting frame 4 are coated with an electrophoretic process. Since the base 1, main support 2, connecting frame 3, and mounting frame 4 are in a separate state, the process is relatively convenient. At the same time, after the base 1, main support 2, connecting frame 3, and mounting frame 4 are produced, they can be packaged and stored in sections, which is convenient for handling and transportation, solving the problem of excessive space occupation in existing technologies.

[0028] Please see Figure 1In one embodiment of this utility model, it further includes: a connecting structure 5, which includes a connecting block 501 and a connecting plate 502. The connecting block 501 is fixedly disposed at both ends of the main support 2 in the height direction. The connecting plate 502 is detachably connected to the connecting block 501, and one end of the connecting plate 502 protrudes from the end of the connecting block 501 away from the main support 2. The protruding end of the connecting plate 502 is detachably connected to the adjacent base 1 or connecting frame 3 by bolts.

[0029] In this embodiment, a connecting mechanism structure 5 is provided, which includes a connecting block 501 and a connecting plate 502. During production, the connecting block 501 is welded to both ends of the main support 2 in the height direction, and through holes are opened on the connecting plate 502. Simultaneously, through holes are also opened on the connecting block 501, the base 1, and the connecting frame 3 corresponding to these through holes. During installation, the through holes on the connecting plate 502 are aligned with the through holes on the connecting block 501, the base 1, and the connecting frame 3. Bolts are then installed into the through holes to achieve a detachable connection. Thus, assembly is... It is relatively convenient. Of course, the connecting block 501 can also be directly connected to the base 1 or the connecting frame 3 using bolts. In this case, there are two ways to install the connecting frame 3. One is to install the connecting frame 3 between the main brackets 2. This method requires the bolt to pass through the main bracket 2 and the connecting frame 3 in the horizontal direction at the same time. This will increase the length of the bolt, and the longer the bolt, the easier it is to break. The other method is to install the connecting frame 3 at the top of the main bracket 2. This method requires the bolt to pass through the main bracket 2 and the connecting frame 3 in the vertical direction at the same time. This will also increase the length of the bolt.

[0030] Please see Figure 1 In one embodiment of this utility model, it further includes: a connecting lug 6, which is disposed in the installation area and is disposed along the height direction of the main bracket 2; and a connecting angle bracket 7, which is fixedly disposed at one end of the mounting frame 4, the mounting frame 4 is placed at the upper end of the connecting angle bracket 7, and the connecting angle bracket 7 and the connecting lug 6 are detachably connected by bolts.

[0031] In this embodiment, by setting the connecting lug 6 and the connecting bracket 7, the cross-section of the connecting bracket 7 is U-shaped, and through holes are opened on both the connecting lug 6 and the connecting bracket 7. When the connecting bracket 7 is snapped onto the connecting lug 6, the connecting lug 6 can support the mounting frame 4. The assembly personnel do not need to support the mounting frame 4 all the time, which effectively reduces the assembly difficulty.

[0032] Please see Figure 1 In one embodiment of the present invention, it further includes: a mounting beam 8, which is disposed at the lower end of the base 1 in the height direction.

[0033] In this embodiment, two mounting beams 8 are provided, with an installation space reserved between the two mounting beams 8. Through holes are opened in the thickness direction of the two mounting beams 8. In use, the gap between the two mounting beams 8 is aligned with the vehicle frame, so that the bolts pass through the through holes on the mounting beams 8 and through the vehicle frame to install the battery frame on the vehicle frame.

[0034] Please see Figure 1 In one embodiment of this utility model, it further includes: a reinforcing rib 9, one end of which is connected to the mounting beam 8, and the other end of which is connected to the main support 2.

[0035] In this embodiment, since one end of the reinforcing rib 9 is connected to the main support 2, the load-bearing capacity of the main support 2 can be improved. Since the load at the lower end of the main support 2 is large, the reinforcing rib 9 is connected to the lower end of the main support 2 to prevent the lower end of the main support 2 from deforming under heavy pressure.

[0036] Please see Figure 1 In one embodiment of this utility model, it further includes: a reinforcing rod 11, one end of which is connected to the mounting beam 8, and the other end of which is connected to both ends of the base 1 in the width direction.

[0037] In this embodiment, since the load on the lower end of the main support 2 is large, a reinforcing rod 11 is provided to connect the reinforcing rod 11 to the lower end of the main support 2 to prevent the lower end of the main support 2 from deforming under heavy pressure.

[0038] Please see Figure 1 In one embodiment of the present invention, it further includes a reinforcing bracket 10, which is disposed in the installation area, is connected to the adjacent main bracket 2, and is connected to the base 1.

[0039] In this embodiment, since the load at the lower end of the main support 2 is relatively large, a reinforcing support 10 is also provided. The reinforcing support 10 is also placed at the lower end of the main support 2 to prevent it from deforming.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
