Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery technology, and in particular to a bracket for fixing a lithium battery pack. Background Technology
[0002] High-strength metal materials, such as aluminum alloy and stainless steel, are typically used. Aluminum alloy is lightweight and corrosion-resistant, effectively reducing the weight of the entire bracket while maintaining good performance under complex environmental conditions. Stainless steel has higher strength and better corrosion resistance, making it suitable for applications with extremely high requirements for structural strength and durability. The bracket has multiple clamps inside to fix different sides of the lithium battery pack. The clamps are usually made of materials with a certain degree of elasticity, such as engineering plastics or rubber-coated metal plates. The elastic material can ensure the fixing force while avoiding scratches and squeezing damage to the surface of the battery pack. The clamps may also have some protrusions and grooves, which can better fit the shape of the battery pack shell and further enhance the fixing effect.
[0003] The clamps are connected to the frame body using bolts and nuts to secure the lithium battery pack. The specifications of the bolts and nuts are selected based on the size of the bracket and the required fixing strength. Generally, high-strength stainless steel is used to prevent rust and loosening. However, currently, when the size of the lithium battery pack is slightly larger or smaller than the bracket's design size, it either cannot be placed in the bracket or cannot be effectively fixed after placement, leaving room for movement. This can cause displacement of the electrodes and separator structure inside the battery when the equipment is subjected to vibration, affecting battery performance and lifespan.

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4An embodiment of this utility model provides a bracket for fixing a lithium battery pack, including a hollow box 1. T-shaped brackets 19 can be fixedly connected to the bottom left and right sides of the hollow box 1. A baffle 18 is fixedly connected between adjacent T-shaped brackets 19. A cylindrical lithium battery 11 is installed between adjacent baffles 18. A support plate 8 is fixedly connected to the top of the baffle 18. The hollow box 1 is fixedly connected to the top left side of the support plate 8. An elongated block 10 is fixedly connected to the top of the support plate 8. A connector 20 is fixedly connected to the top right side of the support plate 8. Insertion holes 9 are opened on the left side of the connector 20. An elongated block 22 is fixedly connected to the top rear side of the support plate 8. A top cover 4 is rotatably connected to the top of the inner side of the hollow box 1. Threaded holes 3 are opened at the four corners of the top of the hollow box 1. Bolts 2 are threadedly connected to the inner side of the threaded holes 3.
[0031] Specifically, the T-shaped brackets 19 not only provide support and fixation but also make the entire structure more stable. A baffle 18 is fixedly connected between two adjacent T-shaped brackets 19, which effectively separates the space and facilitates the subsequent installation of components. A cylindrical lithium battery 11 is installed, which serves as the power source for the entire device to ensure that it can meet the needs of long-term operation. The installation position of the cylindrical lithium battery 11 has also been optimized to ensure its safety and stability during use and to withstand forces from all directions, providing strong support for the entire structure. The top of the support plate 8 has a reasonable layout, with a hollow box 1 fixedly connected to the left and a connector 20 fixedly connected to the right. On the rear top of the support plate 8, an elongated block 2 12 is also fixedly connected. This elongated block 2 12 increases the stability of the entire structure and provides more possibilities for the subsequent installation of components.
[0032] Please see the appendix Figure 3 and attached Figure 5 The top cover 4 has four long plates 5 fixedly connected to the top corners. The top of the long plates 5 is rotatably connected to the handle 7. The outer wall of the handle 7 is fixedly connected to the anti-slip sleeve 6. The upper left rear end of the hollow box 1 is fixedly connected to the plus / minus switch 15. The left rear end of the hollow box 1 is fixedly connected to the GPS 13. The top left rear end of the hollow box 1 is fixedly connected to the converter 14. The left front end of the hollow box 1 is fixedly connected to the charging port 16. The left front end of the hollow box 1 is fixedly connected to the outlet 17 near the edge.
[0033] Specifically, these elongated plates 5 not only enhance the structural strength of the top cover 4 but also provide a stable foundation for subsequent installation. A rotating handle 7 is rotatably connected to the top of the elongated plate 5, allowing users to easily open or close the top cover 4. The outer wall of the rotating handle 7 is also carefully fixed with an anti-slip sleeve 6, which uses high-quality anti-slip material to ensure the stability and safety of the user when using the rotating handle 7, allowing for easy operation even with wet or sweaty hands. A GPS 13 is also fixedly connected to the left rear end of the hollow box 1. This GPS 13 module can locate the current position of the device in real time. The converter 14 can convert the DC power provided by the lithium battery into the AC power required by the device, thereby ensuring the normal operation of the device. Near the edge of the left front end of the hollow box 1, an outlet 17 is also fixedly connected. This outlet 17 can be used to discharge any exhaust gas that may be generated inside the device, thereby ensuring the clean and safe operation of the device.
[0034] Working principle: When it is necessary to fix the cylindrical lithium battery 11, first open the top cover 4 rotatably connected to the hollow box 1. Then fix the T-shaped bracket 19 to the bottom inside the hollow box 1 and fix it with the baffle 18. Then pick up the cylindrical lithium battery 11 that needs to be fixed and snap it into the corresponding baffle 18 to block it. The baffle 18 can limit its position. Then fix the support plate 8 to the top of the baffle 18 to limit and block it. This will prevent the cylindrical lithium battery 11 from shaking during the movement, so that the cylindrical lithium battery 11 will not be loose. This will improve the service life of the cylindrical lithium battery 11 and meet the needs of the user.
