Abstract
The present disclosure provides a battery module including a plurality of batteries arranged sequentially in a length direction and a cushion pad disposed between two adjacent batteries in the length direction. The cushion pad can include a main body portion and an extending portion extending outwardly from an end surface of the main body portion in a height direction. The extending portion can include a pair of convex portions and a concave portion between the pair of convex portions. The design can ensure that the cushion pad does not exceed the corresponding surface of the battery in the height direction when pressed, and thus does not affect the flatness of the corresponding surface of the battery.
Claims12
A battery module, comprising:
- (a) a plurality of batteries arranged sequentially in a length direction;
- and
- (b) a cushion pad made of an elastic compressible material disposed between two adjacent batteries in the length direction;
- the cushion pad comprising:
- a main body portion;
- and
- an extending portion extending outwardly from an end surface of the main body portion in a height direction and arranged on the end surface on a lower side of the main body portion in the height direction;
- the extending portion comprising:
- a pair of convex portions arranged in a width direction from two sides of the extending portion and protruding outwardly in the height direction;
- and
- a concave portion located between the pair of convex portions and recessed inwardly in the height direction with respect to the pair of convex portions,
- when the cushion pad is pressed, its deformation leads to formation of an apex from the extending portion,
- wherein the apex and the main body portion do not exceed a corresponding surface of the battery in the height direction.
