Abstract
The utility model relates to a front-wheel driving bicycle. The bicycle comprises a bicycle frame, a front branch part, a front shaft and a hub of the front shaft supported by a rolling bearing, wherein a driving device with gear transmission as well as a pedal mechanism and a saddle connected with the driving device are mounted on one side of the hub of the front shaft of the front branch part. The bicycle is characterized in that the saddle adopts a back-and-forth push-pull saddle structure which comprises a stand pipe assembly structure, a bearing plate and a slide plate, wherein the manger-shaped bearing plate is fixed on the stand pipe assembly structure of the bicycle frame, and the slide plate fixed and integrated with the bottom of the saddle is connected with the bearing plate ina sliding manner. The utility model has the beneficial effects that the improved saddle can be adjusted back and forth in a push-pull manner, so that riders at different heights can comfortably sit onthe saddle with the back abutting against a saddle back; and a rear-wheel driving device is transformed into a front-wheel driving device according to human engineering theories, and by use of the saddle back, a rider sitting on the saddle can exert the force through the movement of the whole body while pedaling, thereby achieving more labor-saving riding.
Description
Technical field
The utility model belongs to bicycle, but relates in particular to a kind of before driving bicycle of seat fore-and-aft adjustment.
Background technology
At present, various forms of bicycles being arranged on market, is to adopt the back-wheel drive mode substantially.That is, trailing wheel is the active opinion, and the bicyclist scrunches pedal and rotates by the flywheel on wheel disc, chain and the trailing wheel, drives front-wheel, and bicycle is moved ahead.Rear drive configuration makes bicyclist's center of gravity all drop on crotch portion by the triangle saddle, damage easily the bicyclist some organ, pathology can appear for a long time.Particularly very big to teenager's harm.The applicant applies for that a kind of before driving does not have sprocket gear transmission bicycle patent, its structure comprises the axle skin that the vehicle frame of bicycle reaches preceding wooden fork part, front axle and supports by antifriction-bearing box, front axle skin one side of wooden fork is provided with gear-driven actuating device and pedal mechanism before described, the bicyclist can cosily be taken advantage of on the seat, near the chair back.Thoroughly avoid the vitals of human body.And the structure of preceding driving device adopts the gear transmission of no chain, can make structure compact more, and driving efficiency is higher.But owing to above-mentioned vehicle type structure reason, the mode that traditional vehicle seat can only be adjusted up and down can not adapt to the requirement of this kind vehicle.Its vehicle seat of bicyclist for different heights must move forward and backward adjustment.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of improved before driving bicycle is provided, but the seat fore-and-aft adjustment after the improvement can cosily be taken advantage of on the seat the bicyclist, near the chair back.Thoroughly avoid the vitals of human body.And the structure of preceding driving device adopts the gear transmission of no chain, can make structure compact more, and driving efficiency is higher.
The utility model for achieving the above object, by the following technical solutions: a kind of before driving bicycle, the vehicle frame and the preceding wooden fork part that comprise bicycle, front axle and the axle skin that supports by antifriction-bearing box thereof, front axle skin one side of wooden fork is provided with gear-driven actuating device and connected pedal mechanism and vehicle seat before described, it is characterized in that: plug-type saddle construction before and after described vehicle seat is made as, described saddle construction is by combination standpipe structure, back plate and slide plate are formed, fixing manger shape back plate on the combination standpipe structure of described vehicle frame describedly is fixed into single-piece slide plate and back plate sliding block joint with the vehicle seat bottom.
One sidewall of described back plate is provided with elongated slot and fixes by the quick detach binding bolt and the slide plate that pass.
Described combination standpipe structure is made up of the person in charge and two looped pipelines, and combination standpipe structure is the bikini areal of support and captives joint with back plate.
Described vehicle seat is made up of backrest and seat support.
Beneficial effect: the seat after the improvement can before and after plug-type adjustment, adapt to the bicyclist of different heights, the bicyclist can cosily be taken advantage of on the seat, near the chair back.It is a principle of utilizing human engineering, and the rear drive equipment of bicycle is become front driving device, can take advantage of on the seat for making the bicyclist, and effect that can the arm-chair back of the body when scrunching, whole body is had an effect.Make ride more laborsaving.Alleviate pressure simultaneously to crotch portion.People's both feet when riding scrunch forward, and health leans against on the chair back backward, and both hands are held the pressure that handlebar also can not bear health, can better concentrate the transmission of power when riding.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
As shown in the figure, a kind of before driving bicycle, the vehicle frame 1 and the preceding wooden fork part 2 that comprise bicycle, front axle 3 and the axle skin 4 that supports by the antifriction-bearing box (not shown) thereof, front axle skin one side of wooden fork is provided with gear-driven actuating device 5 and connected pedal mechanism 6 and vehicle seat 7 before described, plug-type saddle construction before and after described vehicle seat is made as, described saddle construction is made up of combination standpipe structure 8, back plate 9 and slide plate 10, fixing manger shape back plate on the combination standpipe structure of described vehicle frame describedly is fixed into single-piece slide plate and back plate sliding block joint with the vehicle seat bottom.One sidewall of described back plate is provided with elongated slot 11 and fixes with slide plate by the quick detach binding bolt 12 that passes.Described combination standpipe structure is formed by being responsible for 8-1 and two looped pipeline 8-2, and combination standpipe structure is the bikini areal of support and captives joint with back plate.Described vehicle seat is made up of backrest 7-1 and seat support 7-2.
Principle of work: the bicyclist scrunches behind the pedal through the transmission of secondary speedup, drives the flywheel rotation of oppositely installing at last, and the shifting shaft skin rotates the wheel speedup.Its speed speed is with the ratio of number of teeth decision of gear driving pair.Oppositely the flywheel of installing is active with cover in the flywheel, and overcoat is passive, with external tooth shifting shaft skin and wheel revolutions, bicycle is moved ahead.Seat can before and after plug-type adjustment, adapt to the bicyclist of different heights, the bicyclist can cosily be taken advantage of on the seat, near the chair back.This device can be used for bicycle, three-wheel vehicle or the double three-wheel vehicle that scrunches.When form was three-wheel vehicle, two trailing wheels were splayed, its separately the angle of inclination be the 12-14 degree, to improve the defective of easily overturning when traditional three-wheel vehicle is turned.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
