Description
Technical field
The utility model relates to automobile technical fields；More particularly to a kind of automobile B-pillar reinforcement plate structure.
Background technique
The development of new-energy automobile at present is to realize that China is marched toward one of manufacturing power crucial direction by manufacturing big country, with
Conventional fuel oil automobile is compared, and electric car can cause more negative effects colliding, except considering structure caused by colliding
Changing also needs to consider that battery is squeezed outside the injury for causing occupant to receive causes explosion on fire, the installation harm such as point failure.
Battery pack is arranged in below floor more, to guarantee that power battery is not under compression when colliding, battery mounting bracket
And the intensity of battery pack design is larger, so after body bottom transverse strength increase, the floor in body bottom section region and sill strip
The energy for reducing collision cannot be released effectively in lower part so that the more energy of upper body receiving, cause top by deformation
Major injury occupant is crossed in body structure deformation.
Therefore, how can provide one kind can more preferably protect driver and passenger, can preferably absorb caused by collision
Energy can be improved the automobile B-pillar reinforcement plate structure of driver and passenger's safety, and becoming those skilled in the art has skill to be solved
Art problem.
Utility model content
In view of the above shortcomings of the prior art, the technical problem to be solved by the utility model is to how to provide a kind of energy
Enough more preferable protection driver and passenger, can preferably absorb energy caused by collision, can be improved the automobile B of driver and passenger's safety
Column reinforcement plate structure.
In order to solve the above-mentioned technical problem, the utility model uses the following technical solution:
A kind of automobile B-pillar reinforcement plate structure, including whole elongated structure and vertical B column reinforcement plate, B column is reinforced
