Description
Technical field
The utility model relates to a kind of folding bicycle.
Background technology
At present, folding bicycle on market generally adopts circle or oval tubing to make vehicle frame, the front and back attaching parts of burst mostly is single tube, and the front fork of vehicle frame and rear fork are " U " shape to the bilateral support of wheel, the shortcoming existing is: one, after side-foldable, car load becomes " A " shape, thickness is thicker, and volume is larger, and it is very inconvenient to carry and deposit; Two, single tube form makes vehicle rigidity deficiency, increases thickness of pipe and makes again vehicle heaviness; Three, to have profile mechanical, single for these vehicle frames, can not meet current people the aesthetic feeling of material life is pursued.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem proposing in above-mentioned background technology, the utility model provides a kind of folding bicycle, vehicle frame mainly adopts rectangle material, metal sense is stronger, unique style, front and back wheel adopts monolateral support technology to make folding rear integral thickness thinner, carries and deposits conveniently.
The utility model solves the technical scheme that its technical matters adopts: a kind of folding bicycle, vehicle frame has the front pipe that front fork is installed and the middle pipe that vehicle seat is installed, the back vent that on described middle pipe, setting is stretched out backward, described front pipe is connected by the bracing frame of " X " shape with middle pipe, described bracing frame has the first pole and second pole of intersection, be provided with side-foldable device the first pole and the second pole cross part, described front fork is the monolateral stay fork to front wheel supporting, described back vent is the monolateral stay fork that trailing wheel is supported, the first described pole and the cross-sectional plane of the second pole for the benefit of dwindle the rectangle of folding space.The first pole and the second pole can be respectively the forms of single, also can be the forms of two.
In order to make this vehicle frame lighter, in frame materials, can select alloy in lightweight material or carbon fibre material or engineering plastics, so, described vehicle frame is taking side-foldable device as being divided into front frame and rear portion vehicle frame, part and rear portion vehicle frame that described front frame is removed front fork are all the integrative-structure of compression molding respectively, described side-foldable utensil has the part being arranged on front frame, and described side-foldable device also has the part being arranged on the vehicle frame of rear portion.
More specifically, the acute angle angle forming between the first described pole and the second pole is 15 °～40 °, and acute angle angle refers to the angle towards front pipe.
The beneficial effects of the utility model are: folding bicycle of the present utility model has the following advantages:
One, front and back wheel adopts the version of monolateral support, has saved material, and after car body is folding, size is less, and the integral thickness after folding be only 1/4th of common folded bicycle, outward appearance novelty, ultralight ultra-thin, carry and deposit convenience, simple to operate;
Two, main body of vehicle frame structure is mainly used the rectangular material of cross sectional shape, make the metal sense of vehicle frame entirety stronger, unique style, manifest sharp-featured flat form, have more stereovision and rigidity makings, and make the vehicle after folding be " H " shape in conjunction with advantage one, risers is narrower, make folding after size less;
Three, the multiple triangles hollow part forming in whole vehicle frame, not only makes vehicle frame profile concision and compact, also can be convenient to other accessory appliancess such as portable and storing convenient bag.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, front fork, 2, front pipe, 3, middle pipe, 4, back vent, 5, the first pole, 6, the second pole, 7, side-foldable device.
Detailed description of the invention
The vehicle frame of the utility model folding bicycle as shown in Figure 1, vehicle frame has the front pipe 2 that front fork 1 is installed and the middle pipe 3 that vehicle seat is installed, the back vent 4 stretching out is backward set on middle pipe 3, front pipe 2 is connected by the bracing frame of " X " shape with middle pipe 3, bracing frame has the first pole 5 and second pole 6 of intersection, be provided with side-foldable device 7 the first pole 5 and the second pole 6 cross parts, front fork 1 is the monolateral stay fork to front wheel supporting, back vent 4 is the monolateral stay fork that trailing wheel is supported, the version that the first pole 5 is arranged side by side for two poles, the version that the second pole 6 is single pole, this is mainly the problem of considering rigidity, so a pole is wherein arranged to form side by side.
It should be noted that: the left side of the monolateral stay fork of front fork 1 in vehicle frame in Fig. 1, when vehicle frame folding, front fork 1 Rotate 180 degree is to the right side of vehicle frame, the right side of the monolateral stay fork of back vent 4 in vehicle frame simultaneously, after folder folding, can make the front and back wheel of vehicle press close to by illustrated side like this, all outsides in front and back wheel of monolateral stay fork of front fork 1 and back vent 4, can be more convenient for carrying so simultaneously.
The cross-sectional plane of the first pole 5 and the second pole 6 for the benefit of dwindles the rectangle of folding space, has reduced the thickness of vehicle.Vehicle frame is taking side-foldable device 7 as being divided into front frame and rear portion vehicle frame, part and rear portion vehicle frame that front frame is removed front fork 1 are all the integrative-structure of compression molding respectively, side-foldable device 7 has the part being arranged on front frame, and side-foldable device 7 also has the part being arranged on the vehicle frame of rear portion.The acute angle angle forming between the first pole and the second pole is 30 °, and the first pole 5 and the second pole 6 are towards front pipe 2 or be 30 ° towards the angle of middle pipe 3.
Above-mentioned folding bicycle is as shown in Figure 1 a kind of embodiment of the present utility model, in fact the utility model is not limited to this kind of embodiment, can also do the change in some versions with reference to Fig. 1 those skilled in the art, as, wherein the first pole 5 can be also the version of single pole, the second pole 6 can be also the version that two poles are arranged side by side, or two kinds of forms that pole is all two poles.The first pole 5 and the second pole 6 can be also that other between 15 ° to 40 ° is arbitrarily angled towards front pipe 2 or towards the angle of middle pipe 3.
