technical field

The utility model relates to the technical field of accumulators, in particular to an anti-extrusion lead-carbon accumulator.

Background technique

At present, electric bicycles are more and more favored by consumers due to their faster, time-saving and labor-saving features than bicycles, and the driving power of electric bicycles comes from batteries. Therefore, the performance of batteries directly affects the use of electric bicycles. , when the storage battery is in the process of transportation or installation, the bottom of the battery tank or the battery shell may be broken due to uncertain external impacts, resulting in battery leakage and loss of electrical performance, while the shell of the existing lead-carbon battery Generally, resin is used as raw material, and its thickness is designed according to the assembly pressure and the internal pressure requirements that may be generated when the battery is charged and discharged. Therefore, when the battery receives an uncertain external impact, the battery shell may rupture, resulting in battery leakage and electrical performance. For example, the patent No. 201320882427.X includes safety valves, terminals, battery covers, battery tanks, plate groups, and electrolytes. Several ventilation holes arranged in parallel up and down are arranged between the battery cells. The ventilation hole runs through the entire battery along the front and back directions. Although it can solve the battery swelling and cracking caused by temperature rise, when the battery receives an uncertain external impact, the battery case will rupture.
