Description

Damper bicycle frame

The utility model relates to a kind of bicycle rack, and specifically it belongs to a kind of bicycle rack that has spring vibration damper.

Traditional bicycle rack, generally by preceding pipe, go up pipe, pipe, standpipe, center tap, chain stay pipe, upright breeches pipe, flat upright fork-join sheet etc. are formed down, welding back integral structure is diamond pattern, pipe wherein, go up pipe, triangle before pipe, standpipe, center tap constitute down, standpipe, chain stay pipe, upright breeches pipe, flat upright fork-join sheet constitute Vee formation.Great majority such as the mountain bike of rising in recent years, sports type sport car, common car also adopt this structure, the two casts down of the general employing of the vehicle frame of lady's bicycle.No matter diamond pattern still is two casts down, its major defect is that this structure can't be avoided causing the vehicle body vibrations because of Uneven road, thereby cause road-holding property poor, long-distance riding is easy to generate fatigue, particularly spondylodynia, cardiac, long-distance riding is a kind of activity of danger on ups and downs road surface.In order to address this problem, people have thought thousand and one way, as modes such as the damping of employing saddle pipe, front fork dampings, but have poor, the complex structure and other problems of damping effect to some extent; Abroad the someone adopts all-hydraulic shock mitigation system, obtains better effects, but with high costs.

The purpose of this utility model is to propose strong, handsome in appearance, the simple in structure damping bicycle stand of a kind of road surface comformability.

The technical solution of the utility model is: a kind of damping bicycle stand, comprise preceding pipe, standpipe, following pipe, center tap, in the V-type that constitutes by standpipe, following pipe, center tap, compression spring is arranged, both ends of the spring has upper spring seat and lower spring cup, lower spring cup is hinged with following pipe, the front end of upper spring seat and A type guide plate is hinged, and the rear end of A type guide plate is connected with hind axle, and the middle part and the standpipe of A type guide plate are hinged.

A type guide plate can be formed by connecting through Connection Block by left guide plate, right guide plate, is fixed with a clip on the standpipe, and there is a flange centre of Connection Block, and flange and standpipe clip are hinged.

Spring and spring perch can adopt thread connecting mode, and lower spring cup is hinged with the clip that is fixed on V-type vehicle frame bottom.The rear end of A type guide plate is flat upright fork-join plate shape.

The utility model compared with prior art owing to used lever principle and adopted spring shock absorption, thus have that the road surface comformability is strong, good damping effect, handsome in appearance, rational in infrastructure, technology is simple, advantage such as with low cost.Experiment shows; bicycle of the present utility model is installed was being cut 10-12CM vertical dimension obstacle and car load when 200CM highly falls ground; the bicyclist does not have the sense of sharp pounding; therefore the utility model can be alleviated the infringement to human central nervous that causes because of vibrations suddenly; reduce long-distance fatigue of riding, especially spondylodynia, cardiac, disabled person are played the certain protection effect.

Further describe the utility model below in conjunction with drawings and Examples:

Wherein 1 is preceding pipe, the 2nd, last pipe, the 3rd, standpipe, the 4th, following pipe, the 5th, center tap, the 6th, right guide plate, the 7th, left guide plate, the 8th, bearing pin, the 9th, upper spring seat, the 10th, lower spring cup, the 11st, damping compression spring, the 12nd, bearing pin, the 13rd, standpipe clip, the 14th, lower tube clip, the 15th, bearing pin, the 16th, Connection Block.

Embodiment:

A kind of bicycle rack of damping is (as Fig. 1, shown in Figure 2), pipe 1 before comprising, last pipe 2, standpipe 3, under manage 4, center tap 5 etc., at standpipe 3, under manage and be welded with standpipe clip 13 and lower tube clip 14 on 4 respectively, protrude at the two ends of standpipe clip 13 and lower tube clip 14, middle porose, in preceding triangle, be provided with damping compression spring 11, upper spring seat 9, lower spring cup 10(as shown in Figure 4), spring perch (9,10) be with screw thread (as shown in Figure 5) on respectively, there is guide plate 6 axial both sides at rear axle, guide plate 7, in the middle of two guide plates the Connection Block 16 of being with wing is arranged, guide plate 6, the rear end of guide plate 7 is flat upright fork-join plate shape, and be connected with hind axle, guide plate 6, guide plate 7 is connected to integral body by the wing of Connection Block 16, form A type guide plate, the flange of Connection Block 16 is hinged (as Fig. 3 with the standpipe clip 13 usefulness bearing pins 12 that are welded on the standpipe 3 simultaneously, shown in Figure 7), it is the lever that can swing of fulcrum that A type guide plate is formed with bearing pin 12, the front end of A type guide plate also is a guide plate 6, and the front end of guide plate 7 and upper spring seat 9 usefulness bearing pins 8 are hinged; Lower spring cup 10 is hinged with the lower tube clip 14 usefulness bearing pins 15 that are welded in down on the pipe 4, adopts threaded connection mode between damping compression spring 11 and upper spring seat 9, the lower spring cup 10.

Because A type guide plate is hinged with bearing pin 12 and standpipe clip 13, thirty years of age pipe clamp 13 is fixed on again on the standpipe 3, is the lever of fulcrum so A type guide plate forms with bearing pin 12.Park on the level land or when riding, because vehicle body deadweight or add the people's that rides body weight, all give hind axle and compression spring 11 downward pressure, spring 11 distortion and generation elastic force make A type guide plate keep balance on certain angle.When rear wheel produces radial runout because of Uneven road, the stressed rear end that changes and pass to guide plate 6, guide plate 7 of trailing wheel, destroy original balance, again because A type guide plate is that fulcrum forms lever with bearing pin 12, so the front end of guide plate certainly leads to the pressure of variation, and passes to upper spring seat 9 with it, at this moment spring 11 stress deformations absorb or release energy, thereby the vibrations that trailing wheel produces are weakened greatly or eliminate, reach the purpose of damping.

The utility model also can adopt two casts down, and at this moment lower tube clip can be fixed under single pipe down or the double joint on the pipe, and other each component locations and connection structure are constant.

The utility model can also adopt bearing or other modes hinged.

The clip that the utility model is used for being hinged with lower spring cup also can be fixed on the lower end of standpipe, can play a supporting role equally.

The utility model also can directly punch on standpipe and be hinged with left guide plate, right guide plate without clip and Connection Block; Also can directly punch and be hinged on the pipe down with lower spring cup.Left and right guide plate can adopt connecting panel to be linked as integral body, also can not connect, and other each component locations and connection structure are constant.

The utility model is handsome in appearance, and rational in infrastructure, with low cost, road surface comformability is strong, good damping effect, can be used for 20 ", 22 ", 24 ", 26 ", 28 " wait each model men and women bicycle, market outlook are wide, have good prospect of export, remarkable in economical benefits.
