Abstract

The invention discloses a reinforcing rib for the lower casing of the battery pack, a battery pack and a vehicle. The reinforcing rib is suitable for being fixed on the lower casing body of the lower casing of the battery pack. The reinforcing rib includes a top wall and a first side wall. and the second side wall, the first side wall and the second side wall extend downwards from the two side edges of the top wall respectively, the lower end of the first side wall and the lower end of the second side wall are respectively provided with a first side wall flanging and a The second side wall flanging, the first side wall flanging and the second side wall flanging respectively extend in a direction away from each other, and a filling space is defined between the first side wall, the second side wall and the top wall, and the filling space Filled with thermosetting resin. According to the reinforcing rib of the embodiment of the present invention, the design thickness of the lower case of the battery pack can be reduced while ensuring high strength of the lower case of the battery pack, thereby reducing the weight of the battery pack and further reducing the weight of the entire vehicle.

Description

technical field

[0001] The invention relates to the field of vehicle manufacturing, in particular to a reinforcing rib for a lower case of a battery pack, a battery pack with the rib and a vehicle with the battery pack. Background technique

[0002] In order to improve the power of the vehicle and reduce fuel consumption, it is necessary to reduce the weight of the vehicle while ensuring the overall strength of the vehicle. In the related art, the battery pack in the vehicle is installed on the vehicle body through the lower shell of the battery pack, which is made of a solid metal plate. Since the lower shell of the battery pack needs to have strong structural strength, the lower shell of the battery pack The design thickness of the body is relatively thick, which increases the weight of the shell under the battery pack and further increases the weight of the vehicle. Contents of the invention

[0003] The present invention aims to solve one of the technical problems in ...
