A new energy vehicle frame based on mortise and tenon technology and its manufacturing process

Abstract

The invention discloses a new energy vehicle frame based on mortise and tenon technology, which comprises a front cover, a battery cover, a front baffle, a bottom plate, side panels, a rear cover and a rear baffle, and the two sides of the bottom plate pass through The mortise and tenon structure is connected with side plates, and the bottom plate and the side plates on both sides form a U-shaped frame structure in cross section. The two sides of the bottom plate and the corresponding side plates are fixedly connected to the battery cover through the tenon structure; the frame The front and rear ends of the structure are respectively provided with a front baffle and a rear baffle, and the front baffle and the rear baffle are respectively connected to the bottom plate and the side plates through a mortise and tenon structure. The opening through which the plate passes. The vehicle frame proposed by the present invention is composed of FRP honeycomb panels as a whole, which is fireproof, low in density and light in weight. The mortise and tenon structure + epoxy adhesive is used between the parts, and the mortise and tenon structure can effectively limit the torsion between the parts in all directions. move, while other connections cannot.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a new energy vehicle frame based on mortise and tenon technology and its manufacturing process. Background technique [0002] Mortise and tenon is a concave-convex connection method used on two wooden components. The protruding part is called tenon (or tenon); the concave part is called tenon (or tenon, tenon and groove), and the tenon and tenon bite together to play a connecting role. This is the main structure of ancient Chinese buildings, furniture and other wooden instruments. The mortise and tenon structure is the combination of tenon and tenon. It is an ingenious combination of more and less, high and low, long and short wood pieces, which can effectively limit the twisting of wood pieces in all directions. The most basic mortise and tenon structure is composed of two components, the mortise of one is inserted into the mortise of the other, so that the two components ar...

Problems solved by technology

However, the use of bolts also has shortcomings, that is, they will become loose after long-term use, resulting in smaller constraints and shaking. Therefore, the use of mortise and tenon structures in conjunction with bolts and nuts can improve the stability and firmness of key positions.
