#-shaped vehicle body rolling protection device of new energy vehicle

Abstract

The invention discloses a #-shaped vehicle body rolling protection device of a new energy vehicle, and the device comprises a connecting frame, wherein the connecting frame is a vehicle body frame, one side of the connecting frame is connected with a column A, the bottom of the column A is connected with the front end of a vehicle, the other end of the connecting frame is connected with a column C, and the column C is connected with the tail of the vehicle body; a B column, wherein one end of the column B is connected to the connecting frame, and the other end of the column B is connected to the vehicle body chassis; and a protection mechanism. According to the invention, the structural strength of the B column is enhanced through the connecting plate, when the B column bears large force, the force of the B column is transmitted to the connecting plate, so that the strength of the B column is enhanced, meanwhile, part of impact force is transmitted to the non-impact side during impact, the impact force is further dispersed, the strength of the whole frame is further improved, a large living space is reserved for people in the automobile, the automobile door is easier to open when the B column does not deform, and self rescue of the people in the automobile is facilitated.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a rollover protection device for a well-shaped body of a new energy vehicle. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Vehicles with new technology and new structure, new energy vehicles include four types of hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV), other new energy sources (such as supercapacitors, high-efficiency energy storage such as flywheels) automobiles, etc. Unconventional vehicle fuels refer to fuels other than gasoline and diesel. Electric vehicles (BEV) refer to vehicles powered by on-board power su...

AI Technical Summary

Problems solved by technology

[0005] Electric vehicles rely on the battery inside the chassis to power the vehicle system. The battery pack of an electric vehicle is heavy, and most of the weight is concentrated on the chassis. Parallel rollover, the B-pillar is directly impacted, and the impact force on the B-pillar is relatively large, which makes the B-pillar easily deformed during rollover, thereby reducing the living space of the driver and rear passengers, and the B-pillar is deformed. The doors on both sides of the seat are not convenient to open
