Description

Simplified electric vehicle frame

Technical Field

The utility model relates to an electric motor car field especially relates to a simplify shape electric motor car frame.

Background

The structural style of the frame limit pipe of present electric motor car is the pipe structure, the reinforcement also is ordinary straight board turn-ups sheet metal component between limit pipe and the side pipe, structural strength is difficult to guarantee, it connects to need supplementary relevant indisputable support of welding and combine relevant welded nut to connect in the fastening connection who moulds the piece with the outside, because the outside has moulded to increase indisputable support as the changeover part between piece and the frame limit pipe, the changeover part is more, the poor will be big more of assembly that the later stage exists, so welding precision to indisputable support and frame limit pipe is just higher, and more indisputable support is yielding, welding stability hardly guarantees, the stability of welding is also not strong, relevant frame weight and cost are all higher.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simplify shape electric motor car frame.

The utility model discloses an innovation point lies in the utility model discloses in the frame limit pipe by the pipe change square pipe into, square limit pipe has great moment of inertia and section modulus than round limit pipe, has great anti-bending antitorque ability for the intensity of whole frame is better. The upper end of the square tube is a plane which is easier to assist the connection of other part structures in terms of the frame structure, the upper end of the frame needs to assist the connection of plastic parts, the square tube can be directly connected with a nut when in use, and the connection of an iron bracket and a welding nut used on the round tube in the past is cancelled by connecting related plastic parts, so that the problem of large assembly difference is solved; in addition, welding parts can be reduced, weight is reduced, welding tools are simplified, and the frame structure is simplified.

In order to realize the purpose of the utility model, the technical proposal of the utility model is that:

the simplified electric vehicle frame comprises a main beam pipe and a lower edge pipe, wherein frame edge pipes are arranged on two sides of the main beam pipe, one ends of the two frame edge pipes are connected to the main beam pipe, the other ends of the two frame edge pipes are connected to the lower edge pipe, and the frame edge pipes are square pipes.

Furthermore, a plurality of welding holes are formed in the frame side pipe, nuts are arranged in the welding holes, and the nuts are connected with the frame side pipe through welding, laser welding or riveting. The welding is easy in the welding hole, and the nut is fixed more firmly.

Furthermore, a plurality of side supports are arranged between the frame side pipe and the lower side pipe, the top of each side support is welded with the frame side pipe, the bottom of each side support is welded with the lower side pipe, each side support comprises a middle outer convex part and side plates located on two sides of the outer convex part, tie holes are formed in the side plates, and T-shaped step nuts are arranged on the outer convex parts. The side brackets increase the strength of the side brackets through the outer convex parts, and the frame side pipes and the lower side pipes are connected through a plurality of side brackets to increase the overall strength of the frame of the electric vehicle; the T-shaped step nut can assist in fixing and assembling the lower plastic bottom support, and the binding hole can assist in inserting the bolt type binding belt in an inserting mode, so that the internal wiring harness is better fixed.

Further, the lower portion of the side bracket is slightly inclined inward. On the one hand, the strength can be increased, on the other hand, the upper part of the side support is a flat end, so that the side support can be better attached and welded with a square pipe, and the lower part of the side support is slightly inclined inwards, so that the side support can be better welded with a lower side pipe.

Further, the top height of the outer convex part is lower than that of the side plate, and the bottom height of the outer convex part is higher than that of the side plate. The bending out of the outer convex part is easier.

The utility model has the advantages that:

1. the utility model discloses change frame limit pipe into square pipe by the pipe, square limit pipe has great moment of inertia and section modulus than the round limit pipe, has great anti-bending antitorque ability for the intensity of whole frame is better. From the frame structure, the upper end of the square pipe is a plane to facilitate the connection of other part structures, the upper end of the frame needs to assist the connection of plastic parts, the square pipe can be directly connected with a nut, and the connection of an iron bracket and a welding nut used on the conventional round pipe is cancelled by connecting related plastic parts, so that the problem of large assembly difference is solved; in addition, welding parts can be reduced, weight is reduced, welding tools are simplified, and the frame structure is simplified.

2. The utility model provides a limit support has increased the intensity of self through outer convex part, has increased electric motor car frame's bulk strength through a plurality of limit leg joint between frame limit pipe and the lower border pipe.
