Abstract

The utility model discloses a bicycle which comprises a bicycle frame, pedals, a wheel axle fixed on the bicycle frame and wheels connected with the wheel axle; the bicycle further comprises a bicycle seat support pipe (1) and an arm lever (2); the bicycle seat support pipe (1) is connected with the arm lever (2); the arm lever (2) is connected with an arm lever (4) through a support point (3); the arm lever (4) is connected with an elastomer (5) and pulls the elastomer (5); and the rear end of the pull elastomer (5) is connected with the bicycle frame. According to the bicycle provided by the utility model, as the bicycle frame is stressed forwards, the intensity of a rider is reduced, and thus the purpose of labor conservation is reached.

Description

A kind of bicycle

Technical field

The utility model relates to the vehicle, relates in particular to a kind of bicycle.

Background technology

Existing bicycle structure is science not, because the constraint of the force of habit, people continue always and using; Though bicycle has multiple pattern at present, changes ten thousand times without leaving the original aim or stand, force way is unreasonable; Science is not felt fatigue very after people are ridden for a long time, therefore should cause enough attention.

Summary of the invention

For solving above-mentioned middle problem and the defective that exists, the utility model provides a kind of comfortable labour-saving bicycle of riding to enjoy to people.Its keystone configuration utilizes the weight of people and object; After the support tube that is provided with below the vehicle seat is under pressure, act on the arm bar of fulcrum, owing to be the integrally bending connection between arm bar and the arm bar; Behind the arm bar pressurized; Make arm bar lower end displacement pulling elastic body forward through fulcrum, elastomeric rear end is connected in vehicle frame, and the exercise intensity that causes force structure more can rationally alleviate the cyclist reaches the labour-saving purpose.Said technical scheme is following:

A kind of bicycle comprises:

The wheel that comprises vehicle frame, pedal, is fixed on the wheel shaft on the vehicle frame and links to each other with wheel shaft; It is characterized in that; Said bicycle also comprises vehicle seat support tube (1) and arm bar (2), and said vehicle seat support tube (1) is connected with arm bar (2), and said arm bar (2) is connected with arm bar (4) through fulcrum (3); And arm bar (4) is connected with elastic body (5) and spurs elastic body (5), and the rear end of said elastic body (5) is connected in vehicle frame.

The beneficial effect of the technical scheme that the utility model provides is:

Through making vehicle frame forward stressed, alleviate cyclist's intensity, reach the labour-saving purpose.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model embodiment is done to describe in detail further below:

As shown in Figure 1; The structure of having showed the utility model, vehicle frame, pedal, the wheel that is fixed on the wheel shaft on the vehicle frame and links to each other with wheel shaft, said bicycle also comprises vehicle seat support tube 1 and arm bar 2; Said vehicle seat support tube 1 is connected with arm bar 2; Said arm bar 2 is connected with arm bar 4 through fulcrum 3, and arm bar 4 is connected with elastic body 5 and spurs elastic body 5, and the rear end of said elastic body 5 is connected in vehicle frame.Said elastic body can be that spring also can be other elastic.

Above-mentioned is after passing through vehicle seat support tube 1 pressurized through human body weight and lever principle; It is acted on the arm bar 2 to bottom offset; The arm of force lower end that makes arm bar 4 through fulcrum 3 is displacement pulling elastic body 5 (present embodiment elastic body 5 be example with the spring) forward; The rear end of spring 5 is connected in vehicle frame, makes that vehicle frame is stressed to drive cyclist acting forward, reaches the labour-saving purpose.

Above-mentioned said vehicle seat standpipe is a slide down dynamic formula standpipe; Said arm bar 2 connects as one through fulcrum 3 bendings with arm bar 4, being fixed on the lower frame rail of said fulcrum (3) rotary type.The vehicle seat standpipe is set to the form of sliding up and down so that behind the vehicle seat pressurized, utilize lever principle through fulcrum 3 and utilize support tube 1 to the effort of bottom offset on arm bar 2 and arm bar 4.Arm bar 4 pulling springs 5, spring 5 rear ends are connected in vehicle frame, thereby make the cyclist laborsaving.Arm bar 4 is designed to elastic body with spring 5, can be flexible body with the rigidity car body like this, and it is comfortable to ride, and slows down resistance.

Said arm bar 2 is provided with the track groove, and the lower end of said support tube 1 is equipped with a roller 10, and this roller 10 moves at said track groove intrinsic displacement; The saddle tube 1 of said supporting seat is arranged in the support tube.Said support tube is through vehicle frame 7 and vehicle frame 8 support fixation.

The strut bar 6 of vehicle seat support connects to ground behind the bicycle, and is skewed connection.When after vehicle seat also can play power-assisted effect after bearing a heavy burden.

Said bicycle also comprises a storage battery 9, and the rear portion that this storage battery is arranged on support tube 1 is positioned on the arm bar 2.

The preferred embodiment that the above is merely the utility model is not limited to the utility model, and is all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
