The utility model discloses structural design is simple, reasonable, and the design of automobile body skeleton lightweight has improved the intensity and the torsional rigidity of automobile body, has reduced power consumption, and is energy-conserving, has reduced manufacturing cost.
Description
Technical field
The utility model relates to lightweight vehicle technology field, particularly relates to a kind of lightweight four-wheel electric motor car vehicle body framework construction.
Background technology
Four-wheel electric motor car is the vehicle that meets arteries of communication, legislative control on safety requirements, to the environmental concerns less, and the discharge capacity of energy savings and minimizing carbon dioxide, prospect is better.The electrokinetic cell that four-wheel electric motor car adopts mainly is the battery of the types such as plumbic acid, ni-mh and lithium cell.The problems such as the battery-driven car ubiquity total quality of commonly using is larger, and the travelled distance that once charges is few, and consumption of current is larger have restricted applying of battery-driven car.
Electric vehicle body generally adopts the moulding of a plurality of parts steel plate punched, and some adopts high strength steel, but these can not satisfy the power consumption demand of electronlmobil far away.Body structure is complicated, and manufacture difficulty is large, and material is many, not only greatly increased weight and the cost of vehicle frame, and bus body strength is relatively poor, and traveling comfort is relatively poor.The a large amount of electric quantity consumption of battery alleviates tare on body quality, energy savings becomes trend.
Summary of the invention
Based on this, be necessary the problem for the shortcoming of prior art, a kind of lightweight four-wheel electric motor car vehicle body framework construction is provided, its structure design is simple, reasonable, and easy to assembly, body lightening has reduced electric quantity consumption.
A kind of lightweight four-wheel electric motor car vehicle body framework construction, described vehicle body framework construction is high-intensity aluminum alloy framework structure, and described aluminum alloy framework comprises two girders, and two girders be arranged in parallel, the cross sectional shape of described girder is the hollow rectangle ring, is provided with support underframe between described two girders.
Therein among embodiment, described girder one end is provided with front support stand, the other end of described girder is provided with rear bumper, also be provided with bracket of rear mounting between two girders, described bracket of rear mounting is near described rear bumper, the material of described front support stand and rear bumper is high-intensity plastic cement material, and described bracket of rear mounting is the steel-made support frame.
Among embodiment, described support underframe is provided with for the strut bar that supports the seat therein.
Above-mentioned lightweight four-wheel electric motor car vehicle body framework construction, the aluminum alloy framework structure that described vehicle body framework construction adopts high strength, lightweight has not only realized the light-weight design of vehicle body, and has improved intensity and the torsion stiffness of vehicle body.
The body framwork light-weight design, decrease total quality, adopt less capacity of cell can improve the travelled distance of battery-driven car simultaneously, reduced electric quantity consumption, reduce and produce and use cost, prolonged the service life of battery-driven car.
Description of drawings
Fig. 1 is the utility model structural representation.
Below be the explanation of the utility model parts sign flag:
Vehicle body framework construction 100, girder 110, the first kink 111, the second kink 112, support underframe 120, front support stand 130, rear bumper 140, bracket of rear mounting 150, strut bar 160.
The specific embodiment
For further understanding feature of the present utility model, technological means and the specific purposes that reach, function, resolve advantage of the present utility model and spirit, by below in conjunction with accompanying drawing and the specific embodiment detailed description of the present utility model being further understood.
Vehicle body framework construction 100 described in the utility model is the aluminum alloy framework structure of high strength, lightweight.Described aluminum alloy framework comprises two girders that be arranged in parallel 110, and the cross sectional shape of described girder 110 is the hollow rectangle ring.Be provided with support underframe 120 between two girders 110.The material of described support underframe 120 is high-intensity plastic cement material.Described girder 110 is hollow structure, and described aluminum alloy framework has not only been realized the light-weight design of vehicle body, and has improved intensity and the torsion stiffness of vehicle body.Aluminum alloy has that excellent weldability, extrusion forming and machinability are good, and resistance to corrosion is good, the advantage such as indeformable after the high and processing of toughness.
Described girder 110 has the first kink 111 and the second kink 112, and described girder 110 1 ends are provided with front support stand 130, and described front support stand 130 is arranged on described the first kink 111, and the other end of described girder 110 is provided with rear bumper 140.Also be provided with bracket of rear mounting 150 between two girders 110, described bracket of rear mounting 150 is arranged on described the second kink 112.Described bracket of rear mounting 150 is near described rear bumper 140, and the material of described front support stand 130 and rear bumper 140 is high-intensity plastic cement material, and described bracket of rear mounting 150 is the steel-made support frame.
Described support underframe 120 is provided with for the strut bar 160 that supports the seat.
In sum, the aluminum alloy framework structure that vehicle body framework construction 100 described in the utility model adopts high strength, lightweight has not only realized the light-weight design of vehicle body, and has improved intensity and the torsion stiffness of vehicle body.The body framwork light-weight design, decrease total quality, reduced electric quantity consumption, reduce to produce and use cost, prolonged the service life of battery-driven car.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
