Abstract
A frame on an electric bicycle or a bicycle comprises a front beam, a middle beam and a rear beam, one end of the middle beam is connected with the front beam, the other end of the middle beam is connected with the rear beam, the front beam, the middle beam and the rear beam form a front triangle, the upper portion of the front beam is connected with a handlebar, the lower portion of the front beam is connected with a front fork of the electric bicycle or the bicycle, and the upper portion of the rear beam is connected with a saddle while the lower portion of the rear beam is connected with a transmission. The middle beam is composed of a plurality of branch pipes in parallel, a shock absorbing spring is arranged in the space formed by the branch pipes. The frame on the electric bicycle or the bicycle is capable of increasing strength of the integral frame, adopts a plurality of light branch pipes rather than a heavy frame on the electric bicycle, not only is firmer, but can reduce weight of the electric bicycle or the bicycle, and accordingly saves cost.
Description
Technical field
The utility model relates to the assembly of making on a kind of bicycle or the battery-driven car, is specifically related to the vehicle frame on a kind of battery-driven car or the bicycle.
Background technology
On bicycle or battery-driven car, the header portion of traditional vehicle frame all is the pipe fitting of steel.
But traditional header portion is owing to be single steel pipe, and its weight is bigger, is difficult to allow product lightly carry easily, does not meet the lightening development tendency of product.
In addition, the header portion of vehicle frame is made with a pipe fitting, and the intensity of vehicle frame is also poor, influences safety.Simultaneously, the big and heavy external form of crossbeam also influences attractive in appearance.
The utility model content
At above-mentioned defective, the utility model provides the vehicle frame on a kind of battery-driven car or the bicycle, with the bicycle of solution prior art or the not enough problem of frame strength of battery-driven car.
For achieving the above object, the utility model has adopted following technical scheme:
Vehicle frame on a kind of battery-driven car or the bicycle, comprise front-axle beam, central sill and the back rest, one end of central sill connects front-axle beam, the other end connects the back rest, triangle before front-axle beam, central sill and the back rest are formed, and, the top of front-axle beam connects handle portion, its underpart connects the front fork part of car, and the top of the back rest connects the seat cushion part, and its underpart connects the variable part.
Before forming, front-axle beam, central sill and the back rest in the triangular space, shock-proof spring is set.
Central sill is made of side by side some arms, in the space that those arms are formed shock-proof spring is set.
Front-axle beam, central sill and the back rest are made up of arm respectively, and those arms are hollow tube body.
Front-axle beam comprises the bend pipe with certain radian.
Owing to adopted above technical characterictic, made the utility model have following advantage and good effect than prior art:
In sum, adopt the vehicle frame on battery-driven car of the present utility model or the bicycle, can promote the intensity of whole vehicle frame.
In addition, the utility model need not vehicle frame big and heavy on standard bicycle or the battery-driven car, and only uses several light-duty arms, and is not only more firm, can also alleviate the weight of vehicle, saves cost.
Central sill is made of side by side some arms, in the space that those arms are formed shock-proof spring is set, and this mode has also reduced the space.
Description of drawings
Fig. 1 is the structural representation of a kind of car embodiment of the present utility model;
Fig. 2 is the structural representation of a kind of embodiment of vehicle frame among Fig. 1;
The specific embodiment
Below in conjunction with accompanying drawing, the utility model done being described in further detail.
Please consult Fig. 1 to Fig. 2 respectively, vehicle frame 10 on a kind of battery-driven car or the bicycle, comprise that front-axle beam 12, central sill 11 and an end of the back rest 13. central sills 11 are connected front-axle beam 12, the other end connects the back rest 13. central sills 11 and is made up of side by side some arms 111, the top that shock-proof spring 14. front-axle beams 12 are set in the space that those arms 111 are formed connects handle portion 21, and its underpart connects the front fork part 22 of car.Front-axle beam comprises the bend pipe with certain radian.The top of the back rest 13 connects seat cushion part 23, and its underpart connects variable part 24.Front-axle beam 12, central sill 11 and the back rest 13 are formed preceding triangle, have strengthened the intensity of vehicle frame.In addition, front-axle beam 12, central sill 11 and the back rest 13 can be formed preceding triangular space, and shock-proof spring (not illustrating) is set therein.
Also have, front-axle beam 12, central sill 11 and the back rest 13 are made up of arm respectively, and those arms can be hollow tube body, and also can be the body of entity, like this, can adopt other as materials such as PVC, can expendable weight.
In sum, adopt the vehicle frame on battery-driven car of the present utility model or the bicycle, need not vehicle frame big and heavy on standard bicycle or the battery-driven car, and only use several light-duty arms, not only more firm, can also alleviate the weight of vehicle, save cost.
More than disclosed only be preferred embodiment of the present utility model; but be not to be used for limiting itself, anyly have the knack of those skilled in the art, under the situation of the utility model spiritual connotation; the equalization of being done changes and changes, and all should drop in the protection domain of the present utility model.
