Embodiment

[0007] Shown in the schematic diagram of the main car body structure, the structure of the present invention has been shown. It has added support parts (3) and displacement parts (as the seat riser (4) and Clothes (thing) frame support bar (6), central axis (5) displacement etc.).

[0008] The added part is the rear support member (3) of the vehicle seat. Its upper end is connected to the rear support point (1) of the vehicle seat, and the lower end is connected to the front frame (2). (3) Make the vehicle frame produce a force forward, which can save 50% of the labor through the test, and the length and length of the support (3) are adjustable. The other part (4) of the displacement vehicle frame determines the front and rear positions of the vehicle frame (4) under the condition that the vehicle seat is invariable in the original vehicle position, and the central axis (5) of the displacement vehicle frame is preferably on the vertical line of the center of gravity of the veh...

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

technical field [0001] The invention relates to a vehicle, in particular to a bicycle. Background technique [0002] The existing bicycle structure is unscientific, and people continue to use it because of the shackles of habitual forces. Although there are many kinds of bicycles, they remain the same. The resistance makes people feel very tired after riding for a long time, so it should be paid enough attention. Contents of the invention [0003] In order to solve the above existing problems and defects, the present invention provides a comfortable and labor-saving bicycle for people to enjoy. This structure utilizes the total weight on the vehicle body. Change the fixed support in the middle of the original car seat to the support that can be rotated up and down (fixed point is movable) before and after the car seat, the front fulcrum of the car seat is connected with the car frame (8) ) is connected with the upper end of the connecting rod (1), and the lower end of t...
