[0028] Please see Figure 1-8 A mobile energy storage battery includes a housing 1 with one open side and a cover 2 covering the opening of the housing 1. A support frame is installed inside the housing 1. The support frame includes a first partition 3 and a second partition 4. The first partition 3 is connected at both ends to the two inner walls of the housing 1, respectively, to divide the internal space of the housing 1 into an upper receiving cavity 5 and a lower receiving cavity. One end of the second partition 4 is connected upwards to the first partition 3, and the other end is connected downwards to the bottom wall of the housing 1, to divide the lower receiving cavity into a left receiving cavity 6 and a right receiving cavity 7. (See also...) Figure 2-3 The first partition 3 has a main wire hole 31 and several auxiliary wire holes 32 that connect the upper accommodating cavity 5 and the right accommodating cavity 7 for cables to pass through. A battery module 8 is installed in the left accommodating cavity 6. Several fixing clips 9 are provided at intervals on the side wall of the second partition 4 to integrate and fix the cables in the right accommodating cavity 7.

[0029] In this embodiment, the opening area of ​​the main wire hole 31 is larger than the opening area of ​​the secondary wire hole 32. The main wire hole 31 is used for large cables to pass through, and the secondary wire hole 32 is used for small wires to pass through. The top surface of the first partition 3 has text engraved on one side of the main wire hole 31 and the secondary wire hole 32 to distinguish wire harnesses of different specifications and types.

[0030] This utility model enables centralized management of cables by dividing the internal space of the housing 1 into different parts for assembling different modules. Different specifications and types of wire harnesses or cables are integrated through the main wire hole 31 and several auxiliary wire holes 32 on the first partition 3. Furthermore, the wire harnesses are fixed on the second partition 4 by the fixing clip 9 located in the right accommodating cavity 7, which avoids tangling between different wire harnesses, facilitates installation and maintenance, and makes the cable arrangement reasonable. The cable storage and installation are convenient, saving time and costs for cable installation and subsequent maintenance.

[0031] Please see Figure 3 The fixing clip 9 has a C-shaped groove at the end away from the second partition 4, and a strap is wrapped around the fixing clip 9. When installing cables, first insert cables of the same specification or type into the C-shaped groove, and then use the strap to secure the cables in the C-shaped groove, thereby avoiding the cables from being distributed haphazardly in the right accommodating cavity 7. The cables are reasonably distributed and clearly categorized, which is beneficial for installation and maintenance.

[0032] In this embodiment, the top surface of the first partition 3 is formed with a plurality of mounting slots 33 for installing other modules, and the main wire hole 31 and a plurality of auxiliary wire holes 32 are opened in the rightmost mounting slot 33.

The bottom end of the second partition plate 4 is connected to the top surface of the support plate 102. A first clearance groove 103 is provided at the connection between the support plate 102 and the top of one of the square tubes 101. In this embodiment, the connection between the support member 10 and the inner wall of the housing 1 is welded. When welding the support member 10 to the inner wall of the housing 1, the welding must be carried out in the first clearance groove 103. This method can avoid the appearance of welding protrusions at the connection between the support plate 102 and the inner wall of the housing 1, and prevent the welding protrusions from protruding and hitting the battery module 8 in the left accommodating cavity 6, thereby improving battery safety.

[0034] Please see Figure 3 A protective component 11 is installed on one side wall of the housing 1, located within the left accommodating cavity 6. The protective component 11 has a hollow inner cavity. A second clearance groove 111 is provided at the connection between the protective component 11 and the inner wall of the housing 1. The function of the second clearance groove 111 is the same as that of the first clearance groove 103, which is to prevent welding protrusions from interfering with the battery module 8. A shock-absorbing pad (not shown in the figure) is provided on the inner wall of the housing 1 facing the cover 2. The shock-absorbing pad has a shock-absorbing function and can also protect the battery module 8.
