Abstract
The utility model provides a bicycle frame relating to the technical field of bicycle, comprising a front fork, a back fork and a bending beam provided with a central axle hole and hinged with the back fork. The utility model is characterized in that the curved beam is connected with a lever by a pivot axle, the lever is positioned on one end of the front surface of the pivot axle, the front fork is sheathed by the lever, the lever is positioned on one end on the back surface of the pivot axle and an impact damper is positioned between the lever and the back fork. The bicycle made of the bicycle frame can improve the shock absorbing effect of the prior bicycle.
Description
Technical field
The utility model relates to technical field of bicycles, especially a kind of cycle frame that has bumper.
Background technology
Bicycle is one of contemporary the most widely used vehicle, and it is light with it, flexibly and cheap and extremely people's welcome.The used vehicle frame of traditional bicycle is not provided with bumper, and people run into Uneven road when walking along the street by bike, bicycle can be difficult to because of jolting controlling party to, need to reduce the speed of a motor vehicle, this not only increases the travel time, and the rider is endured run to the fullest extent the hardship of shake.Now existingly much bumper is housed at bicycle, but its bumper or be contained on the front fork of bicycle, or be contained on the back vent of bicycle, or all install bumper at the front fork and the back vent of bicycle.The front-wheel damping and the rear wheel shock-absorbing of the bicycle of this structure are separate, use poor effect.
Summary of the invention
The utility model provides a kind of cycle frame, and the bicycle that it is used for making can improve existing bicycle damping effect.
To achieve these goals, the scheme that the utility model adopts is: it includes front fork, back vent, and camber beam hinged with described back vent, which is provided with central axis hole, it is characterized in that: be connected with a lever by a hinge at described camber beam, this lever is positioned at described hinge fwd one end suit and described front fork, and this lever is equipped with bumper between end of described hinge back and described back vent.
The front end of above-mentioned camber beam is equipped with the handgrip assembly, and this handgrip assembly is cranked arm by an activity with the top of above-mentioned front fork and is connected.
The utility model compared with prior art has following beneficial effect:
1, owing to is connected with front fork, back vent respectively by lever, the bumper that is connected on the camber beam, the vehicle frame of this structure is used for bicycle, on the one hand, the two-wheel balleting obtains comprehensive and compensates the rear passing on the camber beam that supports human body before and after can making bicycle, thereby can reduce Uneven road to riding personnel's vibrations; On the other hand, bumper is equivalent to be contained in the structure on the short resistance arm of lever, can make the motion of bumper be significantly smaller than the front fork or the motion amplitude of back vent, and the inertia of its inner spring motion can be effectively dwindled in this motion by a small margin of bumper.Its The above results is to make bicycle obtain damping effect preferably.
2, all shared bumper of the forward and backward fork of this cycle frame can make the structure of bicycle more simple, cheap, easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:
Among the embodiment as shown in Figure 1, it includes front fork 2 the utility model, back vent 4 and with back vent 4 pivotally attached camber beams 1, this camber beam which is provided with central axis hole 9, on camber beam 1, be connected with lever 5 by hinge 8, this lever is positioned at hinge 8 fwds one end suit and front fork 2, this lever is equipped with bumper 7 between end of hinge 8 back and back vent 4, when the people runs into uneven road surface at the bicycle made with such vehicle frame of riding, the two-wheel balleting obtains just passing on the camber beam 1 that supports human body comprehensively and after the compensation before and after the bicycle, thereby reduced because Uneven road and vibrations that rider personnel are produced, bumper 7 is equivalent to be contained in the structure on the short resistance arm of lever 5, can make the motion of bumper 7 be significantly smaller than the front fork or the motion amplitude of back vent, the inertia of its inner spring motion can be effectively dwindled in bumper 7 this motions by a small margin, the front end of camber beam 1 is equipped with handgrip assembly 3, cranks arm by activity and 6 be connected in the top of this handgrip assembly and front fork 2.
Claims (2)
1, a kind of cycle frame, it includes front fork, back vent, and camber beam hinged with described back vent, which is provided with central axis hole, it is characterized in that: be connected with a lever by a hinge at described camber beam, this lever is positioned at described hinge fwd one end suit and described front fork, and this lever is equipped with bumper between end of described hinge back and described back vent.
2, cycle frame according to claim 1 is characterized in that: the front end of described camber beam is equipped with the handgrip assembly, and this handgrip assembly is cranked arm by an activity with the top of described front fork and is connected.
