Abstract

A kind of three folding bicycles, by vertical tube of front fork, front-axle beam, central sill, the back rest, preceding hinge, hinge and vehicle seat standpipe are constituted afterwards, front-axle beam, central sill, by hinge connection between the back rest, vertical tube of front fork is connected with front-axle beam, vehicle seat lower riser end axis is connected on the back rest, when contraction bicycle, vertical tube of front fork is folded back upon, vehicle seat standpipe is rolled over forward, central sill and back rest doubling, at this moment vertical tube of front fork, central sill and the back rest and vehicle seat standpipe gather together, achieve the effect that vehicle body is made to reduce rapidly, two related wheels just close up together, in left and right side by side relationship, so that entire bicycle is in volume and in shape quite convenient for carrying and parking.

Description

Three folding bicycles

Technical field

The utility model is related to three folding bicycles, the three folding bicycles that are especially convenient for carrying.

Background technology

Now, there are many portable scooters, such as small wheels folding bicycle, electric motor bicycle with folding etc., but do not had A kind of scooter can be widely used, even the people that ordinary bicycle uses is also fewer and fewer, reason is these vehicles in side Just property, comfort, safety, economy etc. Shortcomings, shared bicycle have convenience, safe, economic feature, So be favourably welcome, shared bicycle has the defects of damage rate is high, big age person will not have with, samll cities and towns, although having Portable electric vehicle or bicycle the advantages of having had been provided with safe ready, but have uneconomical, what is had is uncomfortable, so not by It accepts extensively.

Utility model content

In order to overcome the shortcomings of existing portable tool instead of walk, the utility model provides a kind of three folding bicycles, with three folding vehicles Bicycle advantage made of frame is that folding is simple and quick, and volume after folding is small, regular shape is easy to carry, very easy to use, Either go shopping, visit exhibition, the place either to go to office of going home can be with.

The utility model adopts the following technical solution：

Three folding bicycles, including vertical tube of front fork 1, front-axle beam 2, front-wheel 3, preceding hinge 4, rear hinge 5, central sill 6, vehicle seat standpipe 7, The back rest 8, trailing wheel 9, front-axle beam 2 are connected on vertical tube of front fork 1, and front-axle beam 2 and central sill 6 are connected by preceding hinge 4, and central sill 6 and the back rest 8 are by rear Hinge 5 connects, and vehicle seat standpipe 7 is fixed on by cutting with scissors frame on the back rest 8 and trailing wheel 9, and front-wheel 3 is installed on vertical tube of front fork 1, trailing wheel 9 It is installed on the back rest 8.

With the back rest 8 against hinge frame is bent backward after the bending of vehicle seat standpipe 7.

The preceding hinge 4 is opened, and vertical tube of front fork 1 is bent backward, and rear hinge 5 is opened, 8 forward fold of the back rest, and three foldings are certainly Driving is in folded state.

The utility model will be convenient, comfortable safe in one as shared bicycle using bicycle energy made of the vehicle frame Body, comfort level is better than shared bicycle in many cases,.

Specific implementation mode

To keep the purpose of this utility model, technical solution and advantage clearer, below technical side in the utility model Case is clearly and completely described, it is clear that and described embodiment is the utility model a part of the embodiment, rather than all Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise Lower obtained every other embodiment, shall fall within the protection scope of the present invention.

As shown in Figs 1-4, the three folding bicycles of the utility model, including vertical tube of front fork 1, front-axle beam 2, front-wheel 3, preceding hinge 4, Hinge 5, central sill 6, vehicle seat standpipe 7, the back rest 8, trailing wheel 9, front-axle beam 2 are connected on vertical tube of front fork 1 afterwards, and front-axle beam 2 and central sill 6 are by preceding hinge Chain 4 connects, and central sill 6 and the back rest 8 are connected by rear hinge 5, and vehicle seat standpipe 7 is fixed on by cutting with scissors frame on the back rest 8 and trailing wheel 9, front-wheel 3 Be installed on vertical tube of front fork 1, trailing wheel 9 is installed on the back rest 8, the vehicle seat standpipe 7 bending after with the back rest 8 against, hinge frame to After bend, facilitate folding to park.

The preceding hinge 4 is opened, and vertical tube of front fork 1 is bent backward, and rear hinge 5 is opened, 8 forward fold of the back rest, and three foldings are certainly Driving is in folded state, and vertical tube of front fork 1, central sill 6, vehicle seat standpipe 7, the back rest 8 gather together, and having reached makes vehicle body reduce rapidly Effect, related two wheels just close up together so that entire bicycle is in volume and in shape quite convenient for taking It band and parks, either goes shopping, the place visiting exhibition, go home or go to office can carry, in many situations Under, comfort level is better than shared bicycle.

Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that： It still can be with technical scheme described in the above embodiments is modified, or is carried out to which part technical characteristic etc. With replacement；And these modifications or replacements, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution The spirit and scope of scheme.
