Abstract
The utility model relates to a bearing type aluminum alloy vehicle body of an electric automobile. The vehicle body comprises a vehicle body upper part and a vehicle body lower part, wherein all parts of the vehicle body upper part are made of aluminum alloy, a process is of punch forming of aluminum alloy plates via a die, and an aluminum welding technology is adopted for welding all the parts of the vehicle body upper part; and all the parts of the vehicle body lower part are made of the aluminum alloy, the process is of blank-forming of the aluminum alloy plates and aluminum alloy pipes, and the aluminum welding technology is also adopted for welding all the parts of the vehicle body lower part. The aluminum alloy vehicle body has the advantages of very high bearing strength, anti-bending stiffness and anti-torsion stiffness; and after the aluminum alloy material is adopted, the dead weight of a vehicle is greatly reduced and the mileages of continuation of the vehicle can be greatly increased.
Description
One, technical field
The utility model relates to self-supporting body, specifically is a kind of electronlmobil bearing-type car body of aluminum alloy.
Two, background technology
Global oil resources deficient day by day with environmental pollution day by day seriously time; The New-energy electric vehicle of environmental protection becomes market " new lover " gradually; Receive customer's the favor and the approval in market, but the vehicle body of electronlmobil is a bearing-type steel plate vehicle body at present, because the steel plate vehicle body is too heavy; Increase the sole mass of car load greatly, had a strong impact on the mileages of continuation of vehicle.
Three, summary of the invention
The purpose of the utility model is exactly the defective that exists to prior art, provides a kind of safe and reliable and increase the electronlmobil bearing-type car body of aluminum alloy of vehicle mileages of continuation.
Its technical scheme is: this vehicle body comprises body top section and body bottom section; Body top section is made up of left and right sides car door (03), left and right sides gusset (04), back wall (06), back cover (07), top cover (11), base plate (15), preceding cover (17), preceding enclosing (21); The material of each parts of body top section is aluminum alloy; Technology be aluminium alloy plate through the die stamping moulding, adopt the aluminium welding technology to be welded into body top section with top; Body bottom section is made up of preceding shockproof mount (01), middle cant beam (02), back insurance beam (05), back shockproof mount (08), back cant beam (09), after cross member (10), back arm seat (12), left longeron (13), right vertical beam (14), front cross rail (16), front arm seat (18), preceding cant beam (19), preceding insurance beam (20); The material of each parts of body bottom section is aluminum alloy; Technology is aluminium alloy plate and aluminium-alloy pipe blanking forming, adopts the aluminium welding technology to be welded into body bottom section with top; Adopt the aluminium welding technology that body top section and body bottom section weld together are become electronlmobil bearing-type car body of aluminum alloy then; Body top section and the body bottom section common bearing load that becomes one; Body bottom section is each assembly to be installed and to be born the matrix of various load, and body top section helps the load of reinforcing body bottom section and sharing body bottom section to a certain extent.
The rigidity space structure of the utility model electronlmobil bearing-type car body of aluminum alloy has very high loading strength, counter-bending and torsion proof rigidity; After adopting aluminum alloy material, alleviated the sole mass of vehicle greatly, and increased the mileages of continuation of vehicle greatly, data show: vehicular gross combined weight alleviates 25%-30%, and the mileages of continuation of vehicle has increased more than 35%.
