Description

Technical Field

[0001] The utility model relates to the technical field of solid-state lithium batteries, in particular to a solid-state lithium battery protection buffer device capable of reducing collisions. Background Art

[0002] Solid-state lithium batteries are batteries that use solid electrolytes instead of liquid electrolytes in traditional lithium batteries. Compared with traditional lithium-ion batteries, solid-state lithium batteries have higher safety and higher energy density because solid electrolytes can provide better ionic conductivity and are not prone to leakage and explosion. Existing solid-state lithium batteries are usually fixed in the use area using a fixed structure during use. Due to certain impacts and vibrations in the external environment, the internal structure of the battery is easily damaged, affecting its performance and lifespan. Therefore, we have proposed a solid-state lithium battery protection buffer device that can reduce collisions in order to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the problem of existing solid-state lithium batteries, fixed structures are usually used to fix the lithium batteries in the use area. Due to certain impacts and vibrations in the external environment, the internal structure of the battery can be easily damaged, affecting its performance and life.

[0005] Preferably, the anti-collision plate is connected to the protective frame through the spring, so that when a collision occurs, the anti-collision plate can absorb and disperse the impact force, reduce the direct damage of the impact to the battery unit, reduce the frequency of battery replacement, and improve the safety of the battery. When the two sets of anti-collision plates are hit and use the spring to rebound, the movable plate is used to assist in telescopic buffering along the inside of the fixed plate, thereby increasing the energy absorption area, so that it can better adapt to the collision force and direction during the collision, and the fixed plate is combined with the movable rod to increase the stable connection of the entire anti-collision plate, thereby improving the buffering effect. After the battery body is installed inside the bracket, multiple sets of pressure plates are used for gluing and positioning, thereby ensuring that the battery body has a better fit with the bracket during the installation process, effectively reducing the risk of loosening and displacement of the battery due to vibration and impact during vehicle operation, and improving the overall stability. At the same time, the limit buckle connects the positioning plate and the bracket to fix it, and assists in supporting and positioning the battery, ensuring that the battery body is in the correct position during installation, thereby improving installation stability.

By adopting the anti-collision plate connecting spring to connect to the protective frame, the anti-collision plate can absorb and disperse the impact force in the event of a collision, reduce the direct damage of the impact to the battery cell, reduce the frequency of battery replacement, and improve the safety of the battery.

A connecting frame is provided at one end of the connecting frame, multiple groups of plugs are provided inside the connecting frame, and a partition is provided inside the connecting frame.

[0025] When working, first use the tool docking screws 206 to thread the protective frame and the bracket 207, then put multiple groups of solid-state lithium batteries into the bracket 207, and use multiple groups of pressing plates 208 to stick and fit them to ensure that the battery body 1 has a better fit with the bracket 207 during the installation process, effectively reducing the risk of loosening and displacement of the battery due to vibration and impact during vehicle operation.
