Abstract
A non-bearing frame for an electric automobile belongs to the technical field of manufacturing of electric automobiles and mainly comprises an arched straight longitudinal beam (3) with a downward-bent bottom, a front axle cross beam (2), a front cross beam (1), a rear axle cross beam (6) and a rear cross beam (7) which are arranged at two ends of the straight longitudinal beam (3), a middle cross beam (4) with a threshold (5) arranged at the bottom of the straight longitudinal beam (3), and the like. The utility model discloses a longeron frame structure is straightened to arch, reasonable in design, the structure is simple and easy light and handy, and manufacturing process is simple, and is with low costs. The automobile seat cushion is elastically fixed with an automobile body through the spring or the rubber pad, so that the position of a rider can be correspondingly improved, the requirement of wide visual field of a driver is better met, and a considerable part of impact force during frontal collision is shared. Is particularly suitable for being assembled with a reinforced fiber resin composite material vehicle body and an engineering plastic vehicle body into a whole. The device not only brings convenience to the modification and refitting of the vehicle body, but also is easy to maintain the vehicle body.
Description
Technical field
The utility model relates to a kind of used for electric vehicle non-bearing formula vehicle frame, belongs to the manufacturing technology field of electronlmobil.
Background technology
Vehicle body is an important component part of automobile.By its vehicle body bearing mode classification, can be divided into self-supporting body, body-chassis frame construction and semi-integral body in the existing fuel-engined vehicle.Self-supporting body is made with the sheet metal cold punching, and vehicle frame and vehicle body fuse, and does not have straight girder work.The constructional feature of body-chassis frame construction is that independently vehicle frame is arranged, and its structure mainly contains ladder type frame, peripheral shape vehicle frame, spine shape vehicle frame, truss formula vehicle frame etc.Because the principle of work and the system architecture of electronlmobil all are different from fuel-engined vehicle, therefore, the vehicle frame that above-mentioned fuel-engined vehicle is used is difficult to adapt to the operating needs of electronlmobil.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, and it is light and handy to have a simple structure, the used for electric vehicle non-bearing formula vehicle frame of characteristics such as manufacturing process is simple, and cost is low.
The utility model is a used for electric vehicle non-bearing formula vehicle frame, comprises straight longeron, places the propons crossbeam at straight longeron two ends, front cross rail, back axle crossbeam, after cross member, it is characterized in that straight longeron is an arch configuration curved under the bottom, the bottom of described straight longeron also is provided with the intermediate transverse girder of band threshold.
That described straight longeron can adopt is hollow, thin-walled, rectangle section bar, makes with hot bending process on special-purpose machinery.The material of described straight longeron can be low-carbon alloy steel 08 or 09MnL, structural carbon steel Q235-AF.
The utility model adopts the straight longeron body frame structure for automotive of arch, and reasonable in design, simple structure is light and handy, and manufacturing process is simple, and cost is low.Flexibly fix by spring or rubber pad with vehicle body, can be corresponding raising occupant's position, both satisfied the open requirement of driver's seat better, the impulsive force of considerable part when having shared head-on crash again.Compared with prior art have following outstanding advantage and good effect:
1,, and is connected for elasticity between vehicle frame and the vehicle body because the vibration of automobile is to reach the vehicle body of taking the district by vehicle frame.Therefore, the suffered impulsive force of vehicle body is little, vibrates for a short time, has improved the comfort of taking, and has also reduced the suffered load of vehicle body.
2, for the electronlmobil of body-chassis frame construction, its chassis assembly, electrical motor, speed-changing mechanism, electrokinetic cell etc. are directly installed on the vehicle frame, so be particularly suitable for dressing up one with fortifying fibre resin composite materials vehicle body and engineering plastics body subsystem.Not only remodeling and the repacking to vehicle body brought convenience, and, also be easy to the maintenance of vehicle body.
3, when automobile during, can bear bending, the tersional stress of most of vehicle body, improve bending resistance, the torsional property of electronlmobil at bad road traveling.
Description of drawings
Fig. 1 is an integral structure front view of the present utility model;
Fig. 2 is an integral structure birds-eye view of the present utility model;
Fig. 3 is a working state schematic representation of the present utility model.
The specific embodiment
The utility model places propons crossbeam 2, front cross rail 1, back axle crossbeam 6, the after cross member 7 at straight longeron 3 two ends mainly by the curved down straight longeron 3 of arch in bottom, places intermediate transverse girder 4 formations such as grade of straight longeron 3 bottom band thresholds 5.
The utility model elder generation hot bending on special-purpose machinery is made the straight longeron 3 of arch, on unit clamp, weld each grade crossbeams such as propons crossbeam 2, front cross rail 1, back axle crossbeam 6, after cross member 7, intermediate transverse girder 4 then respectively, and then the threshold 5 of burn-oning gets final product, and manufacture craft is very simple.
The utility model is flexibly fixed with vehicle body by spring or rubber pad.In the electric automobile during traveling process, when being subjected to head-on crash, its impulsive force P will decompose along the crooked position of the straight longeron of arch, promptly transmit (direction shown in arrow in the accompanying drawing 3) to the back lower place, thereby reduced the impulsive force that encloses forward, avoided the intrusion of collision, the safety when having improved collision to operator's compartment 8.
Claims (3)
1, a kind of used for electric vehicle non-bearing formula vehicle frame, comprise straight longeron (3), place the propons crossbeam (2) at straight longeron (3) two ends, front cross rail (1), back axle crossbeam (6), after cross member (7) is characterized in that straight longeron (3) is the curved down arch configuration in bottom, and the bottom of described straight longeron (3) also is provided with the intermediate transverse girder (4) of band threshold (5).
2,, it is characterized in that described straight longeron (3) adopts hollow, thin-walled, rectangle section bar, makes with hot bending process on special-purpose machinery by the described used for electric vehicle non-bearing of claim 1 formula vehicle frame.
3, by claim 1 or 2 described used for electric vehicle non-bearing formula vehicle frames, the material that it is characterized in that described straight longeron (3) is low-carbon alloy steel 08 or 09MnL, structural carbon steel Q235-AF.
