Abstract

The invention discloses a bicycle. The structure thereof is based on the original bicycle which comprises a frame, pedals, wheel shafts fixed on the frame and a seat connected with the wheel shafts, and leads the rider to save labor by utilizing the weight of the bicycle body and directional conversion of force, and the structure is applicable to various bicycles and three-wheel vehicles and the like. The supporting mode of the seat is improved to be a front support and a rear support; a front supporting point is fixed on the frame (8), a rear supporting point is connected on the upper end (1) of a supporting rod and the lower end thereof is connected with the frame (2); as the supporting rod (3) is supported in an inclined manner, the seat is pressed to lead the frame (2) to produce a forward force. The front end of a rear clothes (articles) frame is connected with the frame (9) or (4), the rear end thereof is connected with the frame (9) or (4) by a supporting rod (6) and a central shaft (5) of the bicycle moves backward to be in the range of the front and the rear of the vertical line of the center of the gravity of the seat and has two modes of front and back adjustment or being fixed without adjustment. A rear wheel shaft is fixed on a special position of the frame (10).

Description

Bicycle

Technical field

The present invention relates to a kind of vehicle, relate in particular to a kind of bicycle.

Background technology

Existing bicycle structure is science not, because continuing always, the constraint people of the force of habit using, though bicycle has multiple now, but change ten thousand times without leaving the original aim or stand, be subjected to force direction unreasonable, the weight on the car body is not used, and Uneven road forms resistance, people are ridden for a long time feel to tire out, should cause enough attention.

Summary of the invention

Be problem and the defective that solves above-mentioned existence, the invention provides and a kind ofly riding comfortable, labour-saving bicycle and enjoy to people.This structure has been utilized the total weight on the car body.Becoming original vehicle seat center fixed supports, change now that vehicle seat is forward and backward can to rotate (attachment point is movable) up and down and support into, the vehicle seat front fulcrum is connected support with vehicle frame (8), the vehicle seat rear end is connected with small end (1) by support link (3), the lower end of support link (3) and front vehicle frame (2) can be dynamically connected, and its weight passes to vehicle frame (2) by support link and makes vehicle frame form a kind of power direction of the power (conversion) forward after vehicle seat is stressed.Becoming back clothing (thing) frame is become by original vertical support: the post upper (7) of clothing (thing) frame is connected in clothing (thing) frame, the lower end is connected in vehicle frame (9) or vehicle frame (4), its power that produces forward a kind of power and strut bar (3) generation is united two into one, make the cyclist laborsaving, this is an one.Its two be with axle for bicycle move to backward with the nearest distance range of vehicle seat center of gravity perpendicular line in, make the cyclist good stressed, cyclist's posture similar in appearance to people's running state also can be covert laborsaving.It three is that rear vehicle shaft has special-purpose fixed position to prevent because of assembling wheels makes forward and backward wheel accidentally not on the same line, produces resistance when riding the cyclist is required great effort.It four is that middle shaft position can forward and backward adjustment or do not adjust two kinds of forms and prevent that chain is long and short, and has special purpose parts to prevent axis and vehicle frame out of plumb.

Description of drawings

Accompanying drawing is that main car body improves scheme drawing.

The specific embodiment

Be purpose of the present invention, technical scheme and advantage are clearer, below in conjunction with accompanying drawing embodiment of the present invention are further described:

Embodiment:

Shown in the main car body structural representation, showed structure of the present invention, it has increased again and has supported other part (3) and displacement part (as the displacement etc. backward of vehicle seat standpipe (4) and clothing (thing) frame strut bar (6), axis (5)) in addition except the original in addition part of former car.

Described newly-increased other part is that its upper end of strut member (3) is connected in the strong point (1) behind the vehicle seat behind the vehicle seat, the lower end is connected in front vehicle frame (2), after vehicle seat is stressed, make vehicle frame produce forward a kind of power by vehicle seat strut member (3), can be laborsaving 50% through test, strut member (3) is long and short adjustable.Other part (4) of described displacement vehicle frame is determined the front and back position of its vehicle frame (4) in former car position unmodified situation at the guarantee vehicle seat, displacement in addition part axis (5) is preferably on the vehicle seat center of gravity perpendicular line (and can before and after suitably adjust or do not adjust), with special purpose parts ensure adjust after wherein shaft position perpendicular to vehicle frame.Back clothing (thing) part strut bar (6) adjustable length, the upper end is connected in clothing (thing) part (7), and the lower end is connected in vehicle frame (9) or (4), and point of connection (7) can not be preceding in the trailing wheel vertical center line, to guarantee safe in utilization being advisable.

This bicycle is the improvement (as figure) by body frame structure for automotive in sum, utilize the total weight on the car body to act on the vehicle frame, make vehicle frame obtain forward a kind of power, the person of riding is ridden for a long time reduce 50%～70% strength at repeated alternation, the final main purpose of present case that Here it is.

Though described the present invention by embodiment, those of ordinary skills know that the present invention utilizes the total weight of car body to be auxiliary power source, and its structure has many distortion and variation, and do not take off spirit of the present invention, the claim of application documents of the present invention comprises these distortion and variation.

Claims

1. bicycle, it is characterized in that: comprise vehicle frame, pedal, be fixed on wheel shaft and the continuous vehicle seat of wheel shaft on the vehicle frame based on former bicycle, utilize the total weight (people and thing) on the car body, vehicle seat front end (can rotate up and down) support and connection are in vehicle frame (8), rear end and post upper (1) are rotationally connected, and the strut bar lower end is rotationally connected with vehicle frame (2); Back clothing (thing) frame becomes original vertical support and is the support that turns forward, and post upper is connected in clothing (thing) frame (7), and the lower end is connected in vehicle frame (9) or vehicle frame (4); Bicycle middle shaft is moved to backward in the forward and backward nearest distance of vehicle seat center of gravity perpendicular line; Hind axle has dedicated location to fix.

2. bicycle according to claim 1, it is characterized in that: utilize total weight (people and the thing) vehicle seat on the car body to be back and front supporting by original center support change vehicle seat, front fulcrum is fixed on vehicle frame (8) and goes up (can rotate up and down connection), vehicle seat rear end and post upper (1) are rotationally connected up and down, strut bar lower end and vehicle frame (2) are rotationally connected, after vehicle seat bears a heavy burden, because strut bar tilts to bear a heavy burden to make vehicle frame (2) to produce a kind of power forward, for cyclist's acting, can be laborsaving 50%～60% through test, this body frame structure for automotive closes case and proposes to be patented product.
