Technical Field
The utility model belongs to the technical field of the vehicle, concretely relates to small-size electric automobile lightweight automobile body.
Background
At present, the chassis adopted by the electric automobile is complex, the covering parts are more, the automobile body adopts a metal plate, and a pressure-resistant component is arranged in the automobile body, so that the safety of the automobile is improved. Because the battery capacity adopted by the small-sized electric automobile is relatively small, the vehicle body weight seriously restricts the endurance mileage.
The vehicle chassis in the prior art mainly comprises two longitudinal beams, a plurality of cross beams arranged between the two longitudinal beams and various reinforcing areas used for connecting upright posts and the like, so that the mass is overlarge. The horizontal stress bearing capacity of the chassis is good, but when the chassis faces a rugged road, the horizontal chassis is easy to twist, so that deformation and loosening of the upper connecting piece are caused. The pressure-resistant component of the vehicle body is made of corrugated metal plates or perforated pattern metal plates, and is influenced by the quality of the pressure-resistant component, and the component is thinner, so that the strength is still not high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem that the automobile body of the small and medium-sized electric automobile in the prior art has heavy weight and low strength, and providing a light-weight automobile body of the small electric automobile to solve the defects of the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a light vehicle body of a small electric vehicle comprises a light vehicle body and a chassis, wherein the chassis comprises two longitudinal beams arranged at the bottom of the vehicle body; upper supporting beams are respectively arranged on the longitudinal beams; the front end and the rear end of each upper supporting beam are respectively connected with the longitudinal beam, and a plurality of connecting supports are arranged between the two upper supporting beams; the vehicle body comprises an outer cladding layer, a reinforcing layer, a bottom plate layer, a cavity and an inner lining plate which are sequentially arranged from outside to inside; the reinforcing layer is in a vertical parallel semicircular arc shape protruding outwards.
Furthermore, the front end and the rear end of the longitudinal beam are respectively provided with a front anti-collision beam and a rear anti-collision beam; the two sides of the longitudinal beams are provided with edge beams extending outwards, and a plurality of supports are arranged between the two longitudinal beams.
Furthermore, the front end of the upper supporting beam is connected with the longitudinal beam through a downward arc-shaped bent part, and the rear end of the upper supporting beam is connected with the longitudinal beam through a splayed supporting leg.
Further, the outer cladding layer is made of an aluminum alloy material; the reinforcing layer and the bottom plate layer are made of epoxy resin plates.
Furthermore, the end part of the outer cladding layer is bent inwards to wrap the reinforcing layer and the bottom plate layer and is buckled with the lining plate.
Furthermore, foam strips or sponge strips are arranged in gaps of the reinforcing layer.
Furthermore, be equipped with soundproof cotton layer in the cavity, glass-frame riser, circuit and audio amplifier.
The utility model discloses rational in infrastructure, through the optimization to chassis and automobile body, reduced the weight of automobile body, automobile body intensity not only does not reduce moreover, and certain promotion has in addition, the effectual technical problem who exists among the prior art of having solved.
