Description

Lithium battery protection board mounting structure Technical Field The utility model relates to the technical field of lithium battery protection plates, in particular to a lithium battery protection plate mounting structure. Background The lithium battery protection board mounting structure mainly relates to the design and optimization of a lithium battery management system, and particularly how to effectively protect a lithium battery from multiple risks such as overcurrent, overvoltage and over-temperature in the charging and discharging processes, the lithium battery is widely applied to the fields of portable electronic products, electric automobiles and the like due to high energy density and long service life of the lithium battery, but due to the complexity of internal chemical reaction of the lithium battery, problems such as thermal runaway, battery short circuit, battery overcharge or overdischarge and the like can occur in the using process of the lithium battery, and fire or explosion is caused in severe cases, so that the effect of the lithium battery protection board is very important, and the safety and stability of the battery in the charging and discharging processes can be effectively ensured. The utility model discloses a lithium battery protection shield shock attenuation mounting structure as disclosed in bulletin number CN219086118U, including the battery frame, the equal fixedly connected with curb plate in inside both ends of battery frame, curb plate outer wall one side is provided with down the mounting bracket, the equal fixedly connected with pterygoid lamina in mounting bracket both sides down, one side fixedly connected with rubber pad that the pterygoid lamina is close to the curb plate, one side that the battery frame was kept away from to the mounting bracket down is provided with the mounting bracket, the holding tank has all been seted up to one side that the mounting bracket is close to each other with the lower mounting bracket. According to the lithium battery protection board, the upper mounting frame, the lower mounting frame, the buffer mechanism and the insulating rubber cover are matched, the insulating rubber cover is arranged at the corner of the protection board, the upper mounting frame and the lower mounting frame are sleeved outside the insulating rubber cover, meanwhile, the buffer mechanism is arranged outside the mounting frame, when the protection board and the lithium battery work, the protection board is protected and buffered outside the protection board, impact force is prevented from directly acting on the protection board, and the protection board is effectively protected, so that the protection board is not easy to loosen and damage. The above-mentioned patent design can provide the damping effect to a certain extent, but when facing great vibration or pressure, its damping effect still shows inadequately, is difficult to effectively to strong impact or continuous high-pressure environment, and in this case, damping system can not fully exert its due effect, leads to the protection shield still to receive great impact or displacement, influences holistic stability and life, therefore, need further optimize damping structure, strengthen its bearing capacity under high-intensity vibration or pressure to ensure that equipment can all keep good performance and reliability under various complicacy operational environment.
