Description

Battery cell fall protection structure Technical Field The utility model relates to the technical field of battery protection, in particular to a battery cell falling protection structure. Background The battery cell refers to an electrochemical cell which comprises a positive electrode and a negative electrode, and is not generally directly used. The battery is different from a battery which comprises a protection circuit and a shell, and can be directly used, wherein the battery core is divided into an aluminum shell battery core, a soft package battery core (also called a polymer battery core) and a cylindrical battery core. In general, the battery of the mobile phone adopts an aluminum shell battery core, the digital products such as Bluetooth and the like mostly adopt a soft package battery core, and the battery of the notebook computer adopts a serial-parallel combination of cylindrical battery cores. In the patent application CN113906614B, a battery core is disclosed that includes a flexible housing, first and second electrodes, an electrolyte, and at least one sealing region. The flexible housing includes a peripheral seal at which the housing seals around its periphery. The first and second electrodes each include a first region and a second region protruding from the first region, wherein the first and second regions of the first and second electrodes are disposed within the flexible housing. The battery cells mentioned in the comparative literature are soft package battery cells, and the battery cells are soft due to the fact that the battery cells are exposed outside, and therefore the battery cells are easy to fall and damage before being used and installed. Disclosure of utility model The utility model aims to provide a battery cell falling protection structure, which solves the problem that the existing battery cell is easy to fall and damage. In order to achieve the purpose, the technical scheme is that the battery cell falling protection structure comprises a battery cell and an adjusting sleeve, wherein the upper end and the lower end of the battery cell are respectively clamped with an end sleeve, the side edge of each end sleeve is fixedly connected with a bump, a threaded rod is sleeved in the adjusting sleeve, the tail end of the threaded rod is fixedly connected with a clamping block, the clamping block is clamped with the bumps, the surface of the end sleeve is attached with an end cover, a pole piece protecting sleeve is arranged on the end cover in a communicating manner, and an electrode piece of the battery cell is inserted into the pole piece protecting sleeve. Preferably, a groove is formed in the end sleeve, and the outline of the groove is identical to the outline of the battery cell. Through the setting of recess, the end cover joint of being convenient for is at the tip of battery cell. Preferably, a waist groove is formed in the middle of the end sleeve, and the waist groove penetrates through the end sleeve. Through the arrangement of the waist groove, the electrode plate of the battery cell conveniently passes through the end sleeve. Preferably, the upper end and the lower end of the adjusting sleeve are provided with thread grooves, and the threaded rod is positioned in the thread grooves. Through the design of the bidirectional thread groove, the synchronous reverse movement between the threaded rods can be realized. Preferably, the bottom fixedly connected with rubber card pearl of end cover, rubber card pearl and end cover joint.
