Description

A left and right cross beam for electric vehicle

Technical Field

The utility model relates to left and right cross beams used for electric vehicles, belonging to the technical field of automobile cross beams.

Background technique

An electric vehicle is a vehicle that uses an onboard power source as its motive force, uses an electric motor to drive the wheels, and complies with all requirements of road traffic and safety regulations. Since its impact on the environment is relatively small compared to traditional vehicles, its prospects are widely optimistic. The engine and battery pack of an electric vehicle are installed in the chassis, so gravity will act on the connection between the bottom plate and the left and right beams. The connection only by bolts can easily lead to the risk of misalignment. In order to avoid serious damage in the event of a car collision, an energy absorption box will be installed on the front beam. However, in order to stabilize the rigidity of the existing energy absorption box, the energy absorption effect of the energy absorption box itself is reduced.

Utility Model Content

In view of the problems in the related technology, the utility model proposes a left and right cross beam for an electric vehicle to overcome the above technical problems existing in the existing related technology.

To this end, the specific technical solutions adopted by the utility model are as follows:

A left and right cross beam for an electric vehicle comprises a cross beam body, reinforcement rods are evenly fixed between the cross beam bodies, both ends of the reinforcement rods are fixedly connected to the cross beam body through mounting plates, fixing plates are fixedly provided at both front and rear ends of the cross beam body, energy absorption boxes are fixedly installed on the fixing plates, reinforcement rings are evenly fixed on the energy absorption boxes, and energy absorption plates are provided in the inner cavity of the energy absorption boxes.

Preferably, mounting blocks are evenly fixedly provided on the top of the crossbeam body, and the mounting blocks are fixedly connected to the body of the electric vehicle, and mounting seats are evenly fixedly provided on the reinforcing rods.

Preferably, a positioning groove is provided on the inner wall of the beam body, positioning plates are fixedly provided at both ends of the reinforcing rod, the positioning plates are embedded in the positioning grooves, and the mounting plate is located on the top of the positioning plate and is arranged in an L shape.

Preferably, mounting holes are provided on the mounting plate and on the top of the beam body, and fixing bolts are fixed in the mounting holes.

Preferably, connecting plates are fixedly provided at both ends of the energy absorbing box, and the connecting plates are fixedly connected to the fixing plates by connecting bolts, and a fixing block is fixedly provided on the mounting plate, and the fixing block is in contact with the energy absorbing plate.

Preferably, the energy absorbing plate comprises end plates arranged at both ends, bending plates are evenly fixed between the end plates, and the bending plates are all arranged in a zigzag shape, through holes are evenly opened on the bending plates, and the bending surfaces of the bending plates are in contact with each other.

The beneficial effects of the utility model are:

By setting the reinforcing rod, during installation, the mounting plates at both ends of the reinforcing rod can be dropped on the crossbeam body and fixedly connected by fixing bolts, so as to maintain the overall strength of the crossbeam body. When the reinforcing rod is supported, it will drop on the crossbeam body through the mounting plate, thereby ensuring the reliability of the overall installation of the electric vehicle;

By setting up an energy absorption box, the front and rear cross beams of the electric vehicle are fixedly connected to the energy absorption box. When a collision occurs between the front and rear of the vehicle, the impact force generated by the collision will continuously squeeze the energy absorption box. When the impact force is too large, the energy absorbing blocks in the energy absorption box will be squeezed and deformed. The energy absorption box further absorbs the impact force during the collision, thereby protecting the floor of the electric vehicle and the people inside the vehicle, thereby improving its practicality.
