A highly protected battery box

Abstract

The invention discloses a battery box with high efficiency protection, comprising the following steps: a sealing ring is arranged in the upper cover of the box body; when the upper cover of the box body and the lower case body are closed, the sealing ring is fitted between the inner surface of the upper cover of the box body and the outer surface of the lower case body; when the upper cover of thebox body and the lower case body are closed, the sealing ring is fitted between the inner surface of the upper cover and the outer surface of the lower case body. The panel of the lower box is a sandwich board structure composed of two carbon fiber boards and spider web sandwich. A BMS management system circuit board and a honeycomb-like battery mount rack are arranged in the cavity of the lowerbox body, and the honeycomb-like mount rack is fixedly connected with the lower box body through bolts; The honeycomb-like battery mounting bracket is made of aluminum material and has a hexagonal honeycomb structure. Each hexagonal honeycomb is provided with a cylindrical battery mounting hole. Between that hexagonal honeycomb and the cylindrical battery mount hole, a reinforcing rib is arrange;The ribs of the honeycomb battery mounting frame are filled with a warp knitted spacer fabric and a magnesium hydroxide flame retardant; The axial position of honeycomb-like battery mounting bracket coincides with the direction of travel of the vehicle.

Description

technical field [0001] The invention relates to the field of electric vehicle battery components, in particular to an electric vehicle battery box. Background technique [0002] With the rapid development of electric vehicles in recent years, more and more electric vehicles have emerged and become a new and convenient means of transportation for people. However, in the complex traffic environment, traffic accidents will inevitably occur, which will give people While threatening life safety, it also brings different degrees of property loss. Compared with fuel vehicles, electric vehicles not only need to consider the protection of occupants in collisions, but also battery safety issues unique to electric vehicles. However, the traditional battery box is mainly made of sheet metal stamping, which has a simple structure and lacks the necessary frame structures such as energy absorption and buffering. When an accident occurs, the traditional battery box can not play a good rol...

However, the traditional battery box is mainly made of sheet metal stamping, which has a simple structure and lacks the necessary frame structures such as energy absorption and buffering

When an accident occurs, the traditional battery box can not play a good role in absorbing and protecting the battery, especially when the vehicle is in a high-speed state, causing the battery to withstand a large amount of impact energy, causing short-circuit explosion and other hazards, posing a serious threat to the safety of passengers
