Description
Technical field
The utility model relates to a kind of bicycle, specifically refers to a kind of transverse tube and the adjustable bicycle of vehicle seat spacing.
Background technology
Bicycle is a kind of vehicle of energy-conserving and environment-protective, and it once was one of main vehicle in China town and country.At present, along with the development of economy and technology, four-wheeled vehicle, track traffic become the main traffic instrument of people's trip already in the city, still, along with mankind's activity to day by day increasing the weight of that the earth pollutes, so that the townie bicycle that originally fades out gradually begins again to obtain people's favor.Generally be divided into Collapsible bicycle or Foldable bicycle not in the existing bicycle, the actuating device that includes front-wheel, trailing wheel, front fork, back vent, handle rack, vehicle frame, vehicle seat and drive vehicle wheel rotation, existing driver train mainly comprises foot-operated the driving and driven by power, and the latter is called Electrical Bicycle.Existing handle rack is general main by transverse tube and handle riser are consisted of, transverse tube is installed in handle riser top, the handle riser lower end then be connected to the front-wheel wheel shaft on front fork be connected, so that vehicle frame comprises that the rider passes through the turning handle transverse tube and drives synchronously circumferentially rotation of front fork when turning to, thereby control front-wheel steering.And handle riser is positioned in the front standpipe of vehicle frame front end, and can rotate in front standpipe.
In existing bicycle and Electrical Bicycle, no matter be Collapsible bicycle or Foldable bicycle not, vehicle seat and all are the spacing between the transverse tube fixing can not significantly arbitrarily adjustings, particularly the sort of vehicle frame is that the corresponding described spacing of bicycle of del structure is changeless especially, so be difficult to adapt to the comparatively tall and big or comparatively short and small rider of figure to the demand that this spacing need strengthen or shorten, cause these riders not adjust to the comfortable position of riding vehicle seat and the distance between the transverse tube.If vehicle seat, need to extend arm, low stoop, the high new line to excessive the spacing between the transverse tube when rider rides, make rider's the long-time pressurized of cervical vertebra, easily to the health injury; If vehicle seat is to too small the spacing between the transverse tube, then because rider's trick is difficult to stretch, make vehicle seat, pedal, handle three fulcrum bearing distributions inappropriate, it is not nimble not only to turn, degree of safety reduction by bike; Also can make rider's perineum stressed larger, cause easily that blood flow is obstructed around the perineum, even may cause also that if things go on like this male sex rider suffers from the sterile danger of prostatitis, thus the healthy of rider affected.
The utility model content
The purpose of this utility model provides a kind of transverse tube and the adjustable bicycle of vehicle seat spacing, this bicycle is not under affecting the synchronous situation of circumferentially rotating with the realization front-wheel steering of transverse tube drive front fork, can also by regulate detent mechanism can with handle riser along the length direction of bicycle namely vertically before, after swing to suitable position and located again, so that riding the bicyclist of the suitable various figures of the spacing between transverse tube and the vehicle seat, both guaranteed the comfortable alerting ability of riding, improve the degree of safety ride, can avoid again the higher or shorter rider of figure healthy caused harmful effect.
Above-mentioned purpose of the present utility model realizes by following technical solution: a kind of transverse tube and the adjustable bicycle of vehicle seat spacing, it comprises front-wheel, trailing wheel, front fork, back vent, carrier, vehicle frame, vehicle seat and driver train, wherein, carrier comprises transverse tube and handle riser, vehicle frame then comprises front standpipe, manage behind pipe and the vehicle frame before the vehicle frame, front standpipe is positioned at the front end of the front pipe of vehicle frame, it is characterized in that: described bicycle is also set up one and is used for adjusting the adjusting detent mechanism of spacing between transverse tube and the vehicle seat, described adjusting detent mechanism is mainly by supporting sleeve, rotating connector and length adjustment mechanism form, wherein, the top of supporting sleeve is enclosed within the bottom of handle riser, and be connected in circumferential relatively turnable mode with handle riser, the bottom of described supporting sleeve and described front standpipe are hinged; Described rotating connector is one axially flexible, the member that circumferentially can rotate synchronously with handle riser, rotating connector is positioned at supporting sleeve, captive joint with handle riser in the upper end of rotating connector, captive joint in the upper end that lower end and front fork stretch out in the standpipe in the past, front fork keeps circumferentially rotating synchronously by rotating connector and handle riser, described length adjustment mechanism is comprised of length adjustment piece and locations, described locations is arranged on the front pipe of vehicle frame, described length adjustment piece arranges adjustable length and can cooperate with locations the adjustment structure of locating along its length direction, one end of this length adjustment piece is hinged on the supporting sleeve, the other end is selected some extension position location of matching with described locations in adjustment structure then, so that supporting sleeve, pipe consists of three-legged structure before length adjustment piece and the vehicle frame, locations before location by different length position on the length adjustment piece and the vehicle frame on the pipe cooperates, regulate the angle between the front pipe of handle riser and vehicle frame, thereby realize the spacing between transverse tube and the vehicle seat is regulated or folded.
The utility model is by setting up the adjusting detent mechanism between the handle riser of bicycle and front fork, make handle riser in regulating detent mechanism supporting sleeve and the combined action of length adjustment mechanism under can be vertically forward and backwardly swing to the suitable comfortable position of riding of rider and locate, adjust the spacing between transverse tube and the vehicle seat and folding purpose thereby reach, the rider can be adjusted the spacing between transverse tube and the vehicle seat according to self height, in order to allow bicycle can adapt to the comfortable demand of riding of rider of various builds, be conducive to the healthy of rider; Simultaneously, rotating connector in this adjusting detent mechanism plays transmitting torque, the moment of torsion that is about to handle riser passes to front fork, therefore but need it to have and axially flexible, circumferentially can rotate synchronously not only drift angle but also eccentric dual-use function with handle riser, so that when the rider turns to when riding, the turning handle standpipe, handle riser by rotating connector drive the front fork synchronous rotating to, turn to demand when satisfying cycling, simultaneously rotating connector can guarantee again handle riser when regulating the spacing between transverse tube and the vehicle seat nimbly and freely.But rotating connector does not play the supporting handle standpipe, and the load-carrying element of handle riser is described supporting sleeve, realizes by supporting sleeve upper end and the movable connection method of handle riser.
The length adjustment piece of length adjustment mechanism described in the utility model and the installation site of locations also can be exchanged with the described position of preamble, be that locations is arranged on the supporting sleeve, length adjustment piece one end is hinged on the front pipe of vehicle frame, and the other end is then selected a position and cooperated the location with locations in adjustment structure.
