Cushioning explosion-proof battery pack bottom support device for new energy automobile

Abstract

The invention discloses a cushioning explosion-proof battery pack bottom support device for a new energy automobile. The bottom support comprises a bottom support shell, a threaded rod, an air storagebag, a first cushioning air bag and a top cover; a supporting plate is welded to the outer side of the bottom support shell; a threaded rod is connected with the inner side of a sliding groove through a bearing; a bracket is arranged on the inner side of the bottom support shell; an accommodating groove is formed in the bracket; a movable plate is connected with the upper portion of an extrusionpush plate; the first cushioning air bag is embedded in the inner wall of the bottom support shell; heat dissipation holes are formed in the surface of the bottom support shell; a hidden groove is formed in the surface of a connecting shaft; a movable piece is arranged on the outer side of the movable cylinder; and the top cover is fixed to the upper portion of the bottom support shell through bolts. The cushioning explosion-proof battery pack bottom support device for the new energy automobile can perform effective cushioning protection on the battery pack, and can automatically and quickly extinguish fire when the battery is accidentally combusted, so that continuous combustion and explosion of the battery pack are avoided, and the loss is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a shock-absorbing and explosion-proof battery pack bottom support device for new energy vehicles. Background technique [0002] As the reserves of fossil energy continue to decrease and people's awareness of environmental protection continues to increase, new energy vehicles have emerged at the historic moment. Different from traditional vehicles, new energy vehicles are completely driven by electricity. Therefore, the core technology of new energy vehicles lies in batteries. The quality of the battery system determines the quality of new energy vehicles. During the production and assembly of new energy vehicles, in order to effectively install and support the battery pack, it is necessary to use the battery pack bottom support device, but the current battery pack bottom support on the market There are still some deficiencies in the device, such as: [0003] 1. Becau...
