Technical Field

[0001] This application relates to the field of shock absorption and protection technology for energy storage batteries, and in particular to a shock-absorbing energy storage battery. Background Technology

[0002] As a core component of energy storage, energy storage batteries play a crucial role in electric vehicles, grid energy storage, and portable electronic devices. With the rapid development of new energy technologies, the demand for energy storage batteries has increased significantly, and their performance directly affects the operating efficiency and stability of various devices. Especially in applications under extreme conditions, the reliability and safety of energy storage batteries have become a key focus of the industry. Whether it's improving range or extending lifespan, technological advancements in energy storage batteries have provided strong support for the development of modern energy systems. In practical applications, to improve the stability and safety of energy storage batteries, the industry typically employs various methods to protect them. For example, adding a rigid protective shell to the battery to prevent external impacts, or filling the space between the battery and the shell with cushioning materials to absorb vibration energy. In addition, methods include limiting the battery's movement by adding fixed supports, and using elastic components to suspend the battery within the shell to reduce vibration transmission. These methods can alleviate battery damage caused by vibration or impact to some extent, but their implementation methods and technical approaches each have their own emphasis. However, existing protective measures generally suffer from a problem: they cannot effectively isolate mechanical vibrations and impacts during transportation. Especially under complex road conditions, battery components are still subject to significant vibrations, leading to performance degradation and even safety hazards. Therefore, how to further optimize the vibration damping design of batteries has become an urgent technical challenge. Utility Model Content

[0003] The purpose of this application is to overcome the above-mentioned technical problems and provide a shock-absorbing energy storage battery.

[0004] A shock-absorbing energy storage battery includes a housing with a cavity inside. A battery assembly is disposed within the cavity, and a shock-absorbing component is installed on the inner wall of the cavity. The shock-absorbing component includes a shock-absorbing frame disposed within the housing, detachably connected to the top and bottom of the battery assembly to prevent direct contact between the battery assembly and the inner wall of the housing. A shock-absorbing spring and a support rod are provided on the inner wall of the housing, and a shock-absorbing spring is installed between the shock-absorbing frame and the support rod. By adopting this technical solution, during transportation, when the energy storage battery experiences bumps or collisions, the vibration of the housing is transmitted to the shock-absorbing frame through the shock-absorbing spring. The deformation of the shock-absorbing spring can dissipate the shock waves, further reducing the transmission of shock waves to the shock-absorbing frame, thereby reducing the vibration of the battery assembly. Preferably, the support rod is U-shaped, and the shock-absorbing frame passes through the support rod. By adopting this technical solution, during user operation, the support rod limits the movement of the shock-absorbing frame, preventing it from swinging excessively, thus reducing the vibration and sway of the battery assembly. Preferably, one end of the shock-absorbing spring is hinged to the shock-absorbing frame, and the other end is hinged to the support rod. By adopting the above technical solution, the hinged design increases the range of motion of the shock-absorbing spring during use, allowing it to swing vertically and horizontally, further dissipating shock waves and reducing damage to the battery assembly. Preferably, the top and bottom of the shock-absorbing frame are respectively fixedly connected to connecting rods, and the battery assembly is bolted to the connecting rods. By adopting the above technical solution, during use, the bolts connect and fix the battery assembly to the connecting rods, facilitating disassembly and installation between the battery assembly and the shock-absorbing frame. Preferably, the bottom of the housing is provided with four shock-absorbing feet. By adopting the above technical solution, during use, the shock-absorbing feet can reduce the transmission of vibration to the housing, further reducing the transmission of shock waves to the battery assembly. Preferably, the shock-absorbing feet include a support cylinder, inside which a return spring is fixedly connected. The return spring is vertically positioned, and a positioning plate is fixedly connected to the bottom of the housing, with the top of the return spring fixedly connected to the bottom of the positioning plate. By adopting the above technical solution, when the user experiences bumps or impacts, the return spring is compressed or stretched. The deformation of the return spring can absorb the shock wave and reduce its upward transmission. Preferably, a bellows is fixedly connected between the support cylinder and the positioning plate. By adopting the above technical solution, when the user experiences vibration, the bellows will stretch or compress along with the support cylinder, without affecting the deformation of the return spring. Simultaneously, it can prevent dust and impurities from entering the support cylinder and clogging the return spring. Preferably, multiple baffles are fixedly connected to the bottom of the positioning plate, with the baffles evenly spaced along the circumference of the positioning plate and inserted into the support cylinder. By adopting the above technical solution, when vibration causes the return spring to deform, the baffles abut against the inner wall of the support cylinder, limiting the deformation of the return spring and preventing it from exceeding its elastic limit and being damaged.

[0010] The following will be combined with the appendix Figure 1-4 This application provides a clear and complete description of the technical solutions in the embodiments of this utility model. The described embodiments are merely possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can, in conjunction with the embodiments of this utility model, obtain other embodiments without creative effort, and these embodiments are also within the protection scope of this utility model. The inventors of this application have discovered that energy storage batteries cannot effectively isolate mechanical vibration and impact during transportation, leading to battery components being easily affected by vibration, resulting in performance degradation and even safety hazards. Therefore, this application mainly adopts the following solution, achieving the effect of effectively protecting battery components from vibration and impact through a multi-level shock absorption structure. The following is a further detailed description of this application. An embodiment of this application provides a shock-absorbing energy storage battery, referring to... Figure 1 and Figure 2 The system includes a housing 1, a battery assembly 12, and a shock-absorbing assembly 2. The housing 1 has a cavity 11, within which the battery assembly 12 is housed. The shock-absorbing assembly 2 includes a shock-absorbing frame 21, a support rod 22, and a shock-absorbing spring 23. The shock-absorbing frame 21 is detachably connected to the top and bottom of the battery assembly 12, preventing direct contact between the battery assembly 12 and the inner wall of the housing 1. The shock-absorbing spring 23 connects the shock-absorbing frame 21 and the support rod 22, effectively isolating external vibrations from being transmitted to the battery assembly 12. This effect occurs because when the housing 1 is subjected to vibration, the deformation of the shock-absorbing spring 23 absorbs most of the vibration energy, thereby reducing the transmission of vibration to the battery assembly 12.

[0011] Two handles 14 are fixedly connected to the top of the housing 1, which facilitate the transfer of the energy storage battery.

[0012] Reference Figure 3 Specifically, the support rod 22 is U-shaped. The shock absorber 21 passes through the support rod 22, and the support rod 22 limits the shock absorber 21, effectively supporting it.

[0013] Specifically, the top and bottom of the shock absorber 21 are fixedly connected to connecting rods 211, and the battery assembly 12 is bolted to the connecting rods 211. The connecting rods 211 can be made of carbon fiber composite material, which is lightweight and high-strength, and can effectively reduce the overall weight; the bolts can be made of stainless steel and are cylindrical in shape, which can prevent the battery assembly 12 from shifting during vibration.

[0014] Reference Figure 3 and Figure 4 Four shock-absorbing feet 13 are added to the bottom of the housing 1. Each shock-absorbing foot 13 includes a support cylinder 131, a return spring 132, and a positioning plate 133. The positioning plate 133 is fixedly connected to the bottom of the housing 1. The return spring 132 is fixedly connected inside the support cylinder 131, and the top of the return spring 132 is fixedly connected to the bottom of the positioning plate 133. The positioning plate 133 is fixedly fixed to the bottom of the housing 1. By adding shock-absorbing feet 13, the transmission of vibration to the housing 1 can be further reduced, thereby reducing the transmission of shock waves to the battery assembly 12. Specifically, a bellows 134 is also fixedly connected between the support cylinder 131 and the positioning plate 133. The bellows 134 is made of flexible material and can be stretched or compressed along with the support cylinder 131, while preventing dust and impurities from entering the support cylinder 131 and protecting the normal operation of the return spring 132. The bellows 134 can be made of high-temperature resistant rubber and is cylindrical in shape, with good expansion and contraction performance and sealing performance.

[0015] In addition, multiple baffles 135 are fixedly connected to the bottom of the positioning disk 133. The baffles 135 are evenly distributed along the circumference of the positioning disk 133 and are inserted into the support cylinder 131. When vibration causes the return spring 132 to deform, the baffles 135 abut against the inner wall of the support cylinder 131. The baffles 135 limit the deformation of the return spring 132 and prevent the return spring 132 from exceeding its elastic limit and being damaged.

[0016] The implementation principle of this embodiment is as follows: through the design of a multi-stage shock absorption structure, the impact of external vibrations on the battery assembly 12 can be effectively isolated. First, the shock-absorbing spring 23 between the shock-absorbing frame 21 and the support rod 22 can absorb most of the vibration energy, reducing the transmission of vibration to the battery assembly 12; second, the connection structure between the shock-absorbing frame 21 and the battery assembly 12 can ensure the stability of the battery assembly 12 and prevent it from shifting during vibration; finally, the fixing structure between the support rod 22 and the housing 1 can ensure the strength and reliability of the overall structure. These designs significantly improve the stability and safety of the energy storage battery during transportation and solve the problems existing in the prior art.

[0017] By optimizing the design of the shock-absorbing support 13, the overall performance of the energy storage battery can be further improved. The combination of the return spring 132 and the bellows 134 not only absorbs vibration energy from the ground but also prevents dust and impurities from entering the support cylinder 131, protecting the normal operation of the return spring 132. The limiting function of the stop bar 135 prevents the return spring 132 from exceeding its elastic limit and being damaged, ensuring the reliability of the overall structure. These designs significantly improve the stability and safety of the energy storage battery under complex road conditions and solve the problems existing in the prior art. The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
