Description
Technical field
The wood utility model belongs to manually driven bicycle, three-wheel vehicle and moped field thereof.
Background technology
Existing crank mechanism forward type bicycle, the bicycle as chair type and recumbency are ridden because the position of crank mechanism is earlier, makes that the chain that drives trailing wheel is long.The less than of bringing thus one is that chain is difficult to arrange that it is attractive in appearance to influence vehicle; The 2nd, chain is difficult for blocking, and the chain that exposes twines cyclist's the shirt rim or the bottom of s trouser leg easily, causes train operation accident, has potential safety hazard; The 3rd, be unfavorable for the dustproof lubricated of chain, influence lubricating quality and reduce driving efficiency.In addition, the electric assisted bicycle of said structure, its storage battery, chain and car beam all are dispersed placement, cause vehicle structure not compact, use inconvenient.Also have, the seat of bicycle does not possess the massage functions of waving, and long distance causes easily that by bike waist muscle is tired.
Summary of the invention
The purpose of the utility model is to solve above-mentioned deficiency, and the latent chain type bicycle that provides a kind of chain and Che Liang to combine together is to make things convenient for the use of crank mechanism forward type bicycle.
Second purpose of the utility model is the basis with first purpose, is to provide a kind of storage battery and chain all to be hidden in the electric assisted bicycle in the car beam, and the structure with the reduced proper motion car is convenient for people to use.
The 3rd purpose of the utility model is the basis with first, second purpose, is to provide a kind of seat to have the bicycle that waves massage functions, and be tired to alleviate long-distance waist muscle by bike the time.
The basic embodiment of the utility model is: the front-wheel of bicycle is connected through hollow car beam and front fork with trailing wheel, and crank mechanism is positioned at the anterior of hollow car beam and is connected with the flywheel of trailing wheel through chain, it is characterized in that chain is positioned at hollow car beam.The hollow structure of car beam can be an osed top, also can be the hatch frame of flute profile.Chain also can replace with rope or axle.
Second scheme of the utility model is the basis with the first string, it is characterized in that hollow car beam is provided with multiplying wheel, and multiplying wheel is connected with the flywheel of crank mechanism and trailing wheel through chain.
The 3rd scheme of the utility model is the basis with first or second scheme, it is characterized in that being provided with storage battery in the hollow car beam.
The 4th scheme of the utility model is the basis with first or second or the 3rd scheme, and the rear end that it is characterized in that hollow car beam is the bathtub construction of widening, and constitutes beam groove integral type tail-bracket, in the bathtub construction storage battery can also be housed.
The 5th scheme of the utility model is the basis with first or second or the 3rd or the 4th scheme; It is characterized in that hollow car beam is provided with waves vertical beam; Wave vertical beam and be connected with hollow car beam with bumper through bearing pin, seat is equipped with in the upper end of waving vertical beam, and trailing wheel is equipped with in the lower end.
The advantage of the utility model is: the utility model has solved crank mechanism forward type bicycle, the aforementioned problems of bringing owing to chain is long; Also storage battery and chain and Che Liang are combined together, simplified the structure of bicycle effectively; Wave seat and have the effect of movable waist muscle, can alleviate long-distance tiredly by bike, increased the new function of bicycle.These all make the use of bicycle more convenient, and are more practical.Can promote the popular of chair type bicycle thus; Change people's mode by bike; Overcome the following deficiency of existing bicycle: the one, because vehicle seat is less; Cause cyclist's buttocks stressed too concentrated, make the poor blood circulation of this part muscle, cause that easily buttocks is uncomfortable or cause some disease; The 2nd, need forward lean in the time of by bike, make wrist stressed excessive, cause wrist pain or damage easily; The 3rd, owing to mainly be that propulsive effort to pedal receives the restriction of body weight downwards firmly to pedal by bike the time, the power of pedaling of shank can not be given full play to, and road speed, acceleration capability and the hill climbing ability of bicycle all are affected; The 4th,, people's the small of the back does not have hard point in the time of by bike, can only rely on hand that the grip force of handlebar is come balance or the power that supports to pedal to the antagonistic force of health, make from pin, leg, waist, abdomen nervously to whole-body muscles such as chest, arm and hands, cause easy fatigue by bike.
