Embodiment Construction
[0020] see figure 1 , figure 2 The storage battery of the present invention includes a battery tank 2 and a battery cover 1. Each cell of the battery tank is equipped with a pole group. The pole group includes a pole plate 4 and a separator 3. The positive and negative pole plates are alternately arranged, and the adjacent pole plates separated by partitions. In order to solve the problem that the busbar is easily broken due to the vibration of the battery, the present invention has improved the design. Several plate feet 5 are arranged on the lower part of the lower frame of each pole plate, and at the same time, the bottom of the battery tank is provided with plate feet at the positions corresponding to the plate feet. Slot 2-1, the board foot is matched and inserted into the board foot slot, and the board foot slot and the board foot are bonded together by the resin glue layer 6 . The separator of the present invention has a single-piece structure, and the lower part of ...

A lead-acid storage battery with a high-strength vibration-resistant structure comprises a battery jar and a battery cover, pole groups are assembled in single cells of the battery jar, each pole group comprises pole plates and partition plates, plate feet are arranged on the lower portion of the lower frame edge of each pole plate, plate foot inserting grooves are formed in the positions, corresponding to the plate feet, of the bottom of the battery jar, and the plate feet are inserted into the plate foot inserting grooves in a matched mode. And the plate foot inserting grooves and the plate foot are bonded into a whole through a resin adhesive layer. According to the invention, the plate foot and the plate foot slot form a mode of bonding the plate group with the storage battery groove, so that the plate group in the whole storage battery shakes along with the whole storage battery, the amplitude difference of different positions of the busbar is reduced, when the plate group vibrates downwards, the busbar plate lug is not stressed any more, the plate foot becomes a main stress point, and the breakage of the busbar plate lug is reduced. In addition, when the storage battery is vibrated, the pole group does not collide with the shell any more, and the shell is prevented from being damaged.
Description
technical field [0001] The invention relates to a storage battery, in particular to a lead-acid storage battery with a high-strength vibration-resistant structure, belonging to the technical field of storage batteries. Background technique [0002] During the use of the vehicle, the lead-acid battery will vibrate continuously with the driving of the vehicle. With the extension of the use time and the influence of the bad road conditions, the battery is prone to damage, and the breakage of the bus bar is an important factor of damage. Analyze the internal force during the vibration process of the lead-acid battery. When the battery vibrates upwards, the pole group and the shell are in close contact, and the pole group is supported by the upward support force of the shell. At this time, the pole group and the shell vibrate simultaneously without deformation of the busbar ; When the battery vibrates downward, the electrode group is subjected to gravity and the downward pressure...
