Description

Electric vehicle

The present invention relates to an electric vehicle, and more particularly, to an electric vehicle in which a lower cross member on which a battery pack is mounted protects the battery pack in a front collision.

A car is a means of transporting passengers or cargo on the road by generating power from its engine and delivering it to the wheels. Automobiles can be divided into a chassis (body) and the various devices that are organically connected to form a large appearance. The chassis includes the main engines such as power transmission, steering, suspension and braking, as well as the automobile engine that drives driving.

The engine is the driving force for running the automobile. Most automotive engines are four-stroke internal combustion engines. A four-stroke internal combustion engine is an internal combustion engine that finishes one cycle by four strokes of intake, compression, explosion, and exhaust, and is the most common example of a reciprocating engine. Internal combustion engines, which mainly use volatile fuels, compress the fuel in a well-mixed state to achieve complete combustion with oxygen in the air, and then directly obtain the kinetic energy by using the thermal energy generated by the combustion.

Internal combustion engines using these volatile fuels have caused environmental pollution and exhaustion of petroleum resources due to exhaust gas, and as an alternative, electric vehicles powered by electricity have emerged. Electric vehicles are pollution-free cars with no emissions or noise. However, high production costs, low running speeds and short running distances have not been practical.

In recent years, high oil prices and tighter exhaust gas regulations have speeded up the development of electric vehicles, and the market is growing rapidly.

It is an object of the present invention to provide an electric vehicle that can install a battery pack on the lower side of the floor.

Another object of the present invention is to provide an electric vehicle that can prevent the breakage of the battery pack by effectively dispersing the force transmitted when the lower cross member on which the battery pack is mounted.

An electric vehicle according to the present invention for solving the above problems is a front side member; A front side member rear coupled to the rear of the front side member; An outer side member coupled to one side of the front side member rear; A lower reinforcement member coupled to the other side of the front side member rear; A front floor lower side member coupled to the outer side member; A lower cross member coupled to the rear of the front side member rear and coupled to the front floor lower side member and the lower reinforcement member 5 and formed to extend left and right; It includes a battery pack coupled to the lower cross member.

The battery pack may be bolted to the lower cross member.

The battery pack may be coupled to the front floor lower side member.

The battery pack may be bolted to the front floor lower side member.

The front side member may include a front inner side member coupled to the front side member rear, and a front outer side panel coupled to the front inner side panel.

According to the present invention, the force transmitted to the front side member through the front side member is distributed to the front floor lower side member and the lower cross member through the front side member rear, the lower reinforcement member and the outer side member during the front collision of the electric vehicle. Therefore, there is an advantage that collision energy can be efficiently distributed and protect the battery pack.
