Bicycle

Abstract

The invention discloses a bicycle. The structure of the bicycle is based on the prior bicycle comprising a frame, pedals, a wheel axle fixed on the frame, and a bicycle base connected with the wheel axle, the total weight (comprising a person and materials, a battery and the like) on a bicycle body is used, and through the direction change of force, a cyclist saves labor, thus the structure is applicable to electric bicycles, electric tricycles and pedicabs. In addition to the parts of the prior bicycle, the stricture is added with a No.1 piece which is rotatablely connected with a No.2 pieceby using the upper end of the No.1 piece connected on the frame as a center of circle when people ride the bicycle and using the distance between the center of circle and the No.2 piece as a radius, when the No.2 piece is stressed, the No.1 piece plays a role in positioning the center of circle, and a No.5 piece is pressed to match with the No.2 piece to ensure that the No.2 piece performs arc movements up and down to pull (press) a spring 4 to make the bicycle generate forward assisting force. The upper end and the lower end of a No.3 piece are provided with a wear-resistant part respectively, a sliding part is arranged between the No.3 piece and the No.2 piece, and because of uneven road, the loading capacity on the bicycle body is vibrated up and down continuously to make wheels generate resistance, and the spring 4 is pushed or pressed continuously at the time of the vibration to make up the vibration resistance so as to achieve the function of saving labor.

Description

Technical field: [0001] The invention relates to a vehicle, in particular to a bicycle. Background technique: [0002] The structure of existing bicycles is unscientific. Due to the shackles of habitual forces, people continue to use them. Although bicycles have many styles, they remain the same. The direction of force is unreasonable. Unevenness forms resistance and makes people feel very tired after riding for a long time, so it should be paid enough attention to. Invention content: [0003] In order to solve the above-mentioned problems and defects, the present invention provides a comfortable and labor-saving bicycle for people to enjoy. Its main structure makes use of the total weight on the car body to make the No. 2 and No. 5 parts under the seat cooperate with each other and then move up and down in an arc, and pull (press) the moving spring 4 to achieve the direction conversion of the force, so that it can generate forward power. effect. [0004] The present in...

Problems solved by technology

[0002]The existing bicycle structure is unscientific. Due to the shackles of the force of habit, people continue to use it. Although there are many styles of bicycles, they remain unchanged. The direction of the force is unreasonable, the total weight on the car body is not applied, and the uneven road surface forms resistance, which makes people feel very tired after riding for a long time, so it should be paid enough attention
