Description

The folding bicycle of the double; two tail wheel of band

Technical field

This utility model relates to a kind of folding bicycle, in particular to a kind of folding bicycle with double; two tail wheels.

Background technology

Folding bicycle is favored by increasing user due to its simple in construction, easy to use and foldability, but, folding bicycle is after folding, sometimes it is also required to move, for reaching the purpose that folding bicycle can easily be moved after folding, the technology that steamboat is combined by existing multiple trial with folding bicycle at present.Making a general survey of existing various scheme, existence structure more or less is complicated, use is inconvenient, manufacturing cost is high and the problem of mobile effect and placement poor effect after folding.

Therefore how to design a kind of folding bicycle welcome by vast user and there is important practical significance.

Summary of the invention

The purpose of this utility model be in that to provide a kind of simple in construction, easy to use, low cost of manufacture and folding after mobile effect and place the folding bicycle of the double; two tail wheel of respond well band.

For achieving the above object, this utility model adopts the following technical scheme that

A kind of folding bicycle with double; two tail wheels, including chassis assembly, front-wheel, trailing wheel, transmission component, seat-assembly and back rest frame, described chassis assembly includes front end chassis assembly and rear end chassis assembly, described front end chassis assembly and rear end chassis assembly are connected by folding fastener, and it is different in that: both sides, described back rest frame rear end are provided with tail wheel.

As a kind of preferred version, a kind of folding bicycle with double, two tail wheels, including chassis assembly, front-wheel, trailing wheel, transmission component, seat-assembly and back rest frame, described chassis assembly includes front end chassis assembly and rear end chassis assembly, described front end chassis assembly and rear end chassis assembly are connected by folding fastener, it is different in that: described back rest frame also includes double, two tail-wheel assembly, described pair of tail-wheel assembly includes the framework being made up of both sides and transverse link mated with mounting, transverse shaft is set at back-end framework, tail wheel is installed at transverse shaft two ends, described pair of tail-wheel assembly is connected with back rest frame by the connecting rod of framework both sides and transverse direction.

In technique scheme, described pair of tail-wheel assembly is connected by framework and back rest frame are fixing.

In technique scheme, described pair of tail-wheel assembly is removably connected by buckle or rope binding with back rest frame by framework.

In technique scheme, described framework adopts aluminium alloy, titanium alloy or carbon fiber to make.

Beneficial effects of the present invention:

(1) this utility model by increasing double; two tail-wheel assembly on back rest frame, greatly improves the stability of the movement after folding bicycle folds and placement.

(2) fixed position of double; two tail-wheel assemblies that this utility model increases has alternative, under folding bicycle riding condition and folding rear state, brings too big change, the movement after conveniently riding and folding all without to the physical dimension of folding bicycle.

(3) double; two tail-wheel assembly simple in construction that this utility model increases, easily manufactured, production cost is low, compared with other similar products, has the extremely strong market competitiveness.

Fig. 2 is the structural representation of the folding bicycle of the double; two tail-wheel assembly of this utility model back rest frame band；

In figure: chassis assembly 1 (front end chassis assembly 11, rear end chassis assembly 12, folding fastener 13), front-wheel 2, trailing wheel 3, transmission component 4, seat-assembly 5 and back rest frame 6 (double; two tail-wheel assemblies 61, framework 611, transverse shaft 612, tail wheel 613).

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail:

Embodiment 1

As it is shown in figure 1, the folding bicycle of the double; two tail wheel of band of the present utility model, it is made up of chassis assembly 1, front-wheel 2, trailing wheel 3, transmission component 4, seat-assembly 5 and back rest frame 6.

Described chassis assembly 1 is included front end chassis assembly 11 and rear end chassis assembly 12, described front end chassis assembly 11 and rear end chassis assembly 12 and is connected by folding fastener 13.It is different in that, both sides, described back rest frame 6 rear end are respectively arranged with tail wheel 613.

Embodiment 2

As in figure 2 it is shown, the folding bicycle of the double; two tail wheel of band of the present utility model, it is made up of chassis assembly 1, front-wheel 2, trailing wheel 3, transmission component 4, seat-assembly 5 and back rest frame 6.

Described chassis assembly 1 is included front end chassis assembly 11 and rear end chassis assembly 12, described front end chassis assembly 11 and rear end chassis assembly 12 and is connected by folding fastener 13.It is different in that: described back rest frame 6 also includes double; two tail-wheel assembly 61, described pair of tail-wheel assembly 61 includes the framework 611 being made up of both sides and transverse link mated with mounting 6, described framework 611 adopts aluminium alloy to make, transverse shaft 612 is set in framework 611 rear end, tail wheel 613 is installed at transverse shaft 612 two ends, and described pair of tail-wheel assembly 61 is connected with back rest frame 6 by rope binding by framework 611 both sides.

Embodiment 3

In the present embodiment, described pair of tail-wheel assembly 61 is connected with back rest frame 6 by buckle by framework 611 both sides, and meanwhile, described framework 611 adopts carbon fiber to make, and other structures are similar to Example 2.

One of the purpose of this utility model, it is exactly that the folding bicycle being under folded state can easily be promoted as luggage case and drag, for realizing this purpose, this utility model realizes by setting up tail wheel 613 on back rest frame 6, the tail wheel 613 set up has two ways to be connected with back rest frame 6, one is directly to be respectively provided with tail wheel 613 in both sides, back rest frame rear end, as described in Example 1；Another is to set up double; two tail-wheel assembly 61 on back rest frame 6, and described pair of tail-wheel assembly 61 includes the framework 611 being made up of both sides and transverse link mated with mounting 6, sets transverse shaft 612 in framework 611 rear end, and tail wheel 613 is installed at transverse shaft 612 two ends；Another object of the present utility model, it is simply that the folding bicycle being under folded state can steadily be placed, the folding bicycle of the double; two tail wheel of this utility model band, can steadily be placed by double; two tail wheels and seat-assembly 5 or double; two tail wheel and trailing wheel 3 in a folded configuration.Compared with similar products, the simple in construction of tail wheel 613 associated component that this utility model is set up, low cost of manufacture, use procedure facilitates easily-controllable, actual promotes and dragging effect and place respond well, has the stronger market competitiveness.
