Description

Technical Field

[0001] The utility model relates to the technical field of battery pole groups, in particular to a battery pole group fastening support structure. Background Art

[0002] A battery pole group is usually composed of multiple positive plates and negative plates arranged alternately. These plates are immersed in electrolyte. The positive and negative plates are separated by separators (also called separator paper, diaphragms) to prevent short circuits and allow ions in the electrolyte to pass freely to complete electrochemical reactions. The pole group is a key part of the battery for storing and converting electrical energy. Support plates are usually located at the top and bottom of the battery pole group to support the entire pole group structure. Fixing bars are important components connecting the support plates and the pole group. They firmly fix the pole group to the support plates through structures such as slots, slides, threaded rods and fastening nuts. The design of the fixing bars needs to have a certain degree of flexibility and adjustability to accommodate pole groups of different sizes and shapes. Through the joint action of the support plate and the fixing bar, the pole group is fixed inside the battery to prevent it from moving or deforming during operation.

[0003] When the support plate cooperates with the fixing bar to position the battery pole group, if the fixing bar is collided during use, the fixing bar may be deformed, resulting in a movable space between the support plate and the battery pole group, thereby reducing the fastening effect of the battery pole group. Therefore, a battery pole group fastening support structure is proposed to address the above problem. Utility Model Content
