Description
Technical field
The invention belongs to vehicle technology fields, are related to a kind of electromobile frame, especially a kind of vehicle of electric bicycle
Frame.
Background technique
Traditional electromobile frame is all made of steel-tube construction welding assembly and is formed, for example, disclosed in Chinese patent literature it is electronic
Vehicle carriage【Application number 201521000053.X】Or a kind of two-wheeled mothers and sons electromobile frame【Application number 201420146511.X】
Deng.For traditional electromobile frame since the flexural strength of steel pipe itself is smaller, vehicle frame integral strength is lower, is unfavorable for electricity
The driving safety of motor-car；Since steel pipe is round tube, in order to install the accessory of electric vehicle on steel pipe type vehicle frame, need in steel pipe
Corresponding position welding has the installation sheet of mounting hole, then secures fitments to and realize installation on installation sheet, due to every installation sheet
It is required to be also required to weld between welding and steel pipe, causes the welding point pole of vehicle frame more, and the position of installation sheet is also required to guarantee
In place, therefore the welding sequence of entire vehicle frame is very many and diverse, causes the production efficiency of vehicle frame lower, and higher to labor claim,
Cost of labor is higher；It further, is to require to be directed to being adapted to different battery trucks since the area coverage of steel pipe is smaller
The vehicle frame of the battery truck design specialized of the type, that is, the versatility of the vehicle frame made of steel pipe are lower.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, a kind of electromobile frame is proposed, the present invention
The technical issues of solution is to increase the intensity of electromobile frame and promote versatility.
Object of the invention can be realized by the following technical scheme：
A kind of electromobile frame, including preceding standpipe, back rest frame and the bracket for connecting preceding standpipe and back rest frame, feature exists
