Description

A kind of anti-vibration bicycle

Affiliated field:

The utility model relates to a kind of back anti-vibration structure of bicycle and can be used for the fast folding mode of this kind bicycle.

Technical background:

The higher bicycle of mountain bike and some class has all designed suspension system mostly, and its action principle is that the elastic buffer by Shock absorber absorbs the impact that causes because of road is uneven jockey's health.The production of Shock absorber has realized specialization, and the quality of its quality has direct influence to shock-proof effect, but the unitized construction of vehicle frame and Shock absorber is bigger to the shock-proof effect influence, so constantly design and improvement of people used rational structure, to improve its shock-proof effect.

Anti-vibration structure mainly contains three kinds behind the anti-vibration bicycle commonly used at present, one is a Washdown type, it is similar to the back suspension shock absorbing apparatus of motor bike, Shock absorber is directly installed on centre or both sides (as Fig. 1) of Seat stay, and the Shock absorber of this anti-vibration structure must have long stroke could improve shock-proof effect.

Second kind of structure is lever.Its vehicle frame is divided into front vehicle frame and Vee formation frame two parts, and Vee formation vehicle frame ABC shape triangular in shape is connected also and can rotates (as Fig. 2) around the A point with hinge with front vehicle frame at the A point.Shock absorber is bearing in the C point.When trailing wheel was subjected to ground supporting power f, can make Vee formation frame ABC make clockwise direction around the A point changeed, and it is subjected to the resilient mounting of Shock absorber at the C point, impact energy is absorbed, can directly not affact on the human body that is sitting on the seat cushion, because AB length is greater than AC, so the Shock absorber stroke can significantly reduce.

The third structure is a four link type.(as Fig. 3), front vehicle frame is the fixed triangle form, and back vehicle frame is formed quadrangle ABCD by one section limit of several groups of connecting rods and front vehicle frame, and its four contacts are all formed a four-bar linkage with the hinge connection.Shock absorber is bearing in the E point on the CD bar.When trailing wheel is subjected to ground-surface impulsive force f, can make the AB bar make clockwise direction and rotate around the A point, act on the CD bar by the BC bar, make the CD bar make clockwise direction and rotate, at E point compression Shock absorber, the Shock absorber spring absorbs impact energy, reaches the purpose of shock-absorbing.

Above-mentioned three kinds of anti-vibration structures all can play the shock-absorbing effect, but they have a common defective, but be exactly Shock absorber except the absorbed-in-fracture energy of absorbing vibration, having absorbed also that a part of jockey scrunches can energy.For example in Fig. 3, when jockey's step was stepped on, it is downward that its strength acts near axis (the A point), and at this moment trailing wheel is subjected to the supporting power increasing that ground makes progress, and this power can affact on the Shock absorber compression spring by four-bar linkage.Scrunch energy part like this and become the idle work of compression spring, this is concerning the contest driver who requires powerful force of explosion, and this part energy will cause to closing great influence his achievement.

Summary of the invention:

The purpose of this utility model just provides a kind of anti-vibration structure that is applicable to bicycle and battery-driven car, and releases a kind of fast folding mode that is fit to this kind structure.

Anti-vibration structure of the present utility model as shown in Figure 4, form by several sections such as vehicle frame 1, connecting rod 2, Chain stay 3, Chain stay 4, Shock absorbers 5, one end of the connecting rod 2 D point of hinge-coupled on vehicle frame, the other end connects at A point and Chain stay 3 usefulness hinges, one end of Seat stay 4 and Chain stay are connected in the B point, the other end is connected in C point on the vehicle frame with hinge, the lower end of Shock absorber is installed in by hinge and leans near the F point of A point on connecting rod 2 or the Chain stay 3, and the other end is installed in vehicle frame by hinge or Seat stay leans near the E point of C point.

When jockey's body weight was pressed on the cushion, trailing wheel was subjected to ground-surface supporting power f.Under the effect of f power, Seat stay 4 is tending towards doing clockwise direction and rotates, thereby pull back Chain stay 3, make connecting rod 2 be subjected to backward pulling force at the A point, this pulling force makes connecting rod 2 make clockwise direction around the D point and rotates, and the absorbed-in-fracture energy that the elastic support that Shock absorber is ordered at A produces f power is absorbed, and so reaches the purpose of shock-absorbing.

When the jockey stepped on pedal suddenly, action of gravity was downward in the A point, makes connecting rod make anticlockwise motion, at this moment, Shock absorber is tension state, and the outside size of Shock absorber rigidly fixes with modes such as screw thread or snap rings, therefore it can not tension extend, and can not absorb and pedal the energy of stepping on.On vehicle body, connects the purpose that position that hinge E point or F order can conveniently reach the adjusting shock-proof effect by changing Shock absorber.

This kind structure not only is fit to mountain bike, also is fit to the less city folded bicycle in wheel footpath, below is two kinds of folding modes of this kind structure shock-absorbing car.

A kind of folding mode of this kind structure shock-absorbing car is that Shock absorber 5 is adopted quick disassembled structure with the connection hinge E or the F of vehicle body, untie one of them hinge then bicycle promptly can be folded into shape as Fig. 6.

Another kind of folding mode such as Fig. 5, increase the pole 6 of a transition between the E point on Shock absorber upper end K and the vehicle frame 1, the pole two ends respectively with Shock absorber upper end K and vehicle frame on the E point be connected with hinge, 7 for stoping the shelves button of tenesmus, can change the elastomeric size of its suspension system by the distance of regulating between the EK.When normally driving, because pole 6 stressed making progress, 7 very little strength of need of retaining button can make its location.During folding, kick near the axis of A point downwards, it can be shrunk to shape as Fig. 6 with pin.Front-wheel steering when treating that axis is received the front-wheel top, must be gone back to front-wheel in the contraction process, promptly block axis and can not fall down.During expansion, front-wheel steering one need only be stepped on trailing wheel backward with pin, can be recovered the state that to drive.Though this folding mode can not be with the portable size of car, folding aftercarriage length reduces greatly, and the not increase of folding back thickness, parks by wall to reduce floor area greatly.Folding and expanding all can be finished in 1 second, is folding mode the most efficiently at present, preferablely is, still keeps the overall aesthetic of bicycle when parking after folding.
