Shock-absorbing bicycle frame

Abstract

The invention provides a shock-absorbing bicycle frame. The shock-absorbing bicycle frame comprises a head pipe, an upper pipe, a lower pipe and a vertical pipe. The upper pipe comprises a left branchpipe and a right branch pipe, the insides of the left branch pipe and the right branch pipe are hollow, and inner cylinders are arranged in the left branch pipe and the right branch pipe. Moving rodsare arranged at one ends of the inner cylinders, springs A are arranged on the peripheries of the moving rods, and clamping grooves are formed in one ends of the moving rods. Connecting plates are arranged in the clamping grooves. The head pipe is internally provided with an inner pipe for mounting a handlebar rod, and an upper pressing plate is arranged at the upper end of the inner pipe. A spring B is arranged at the lower end of the upper pressing plate, and a lower pressing plate is arranged at the lower end of the spring B. According to the shock-absorbing bicycle frame, in the riding process, both the pressure on a saddle and the bumpy driving of a rear wheel on the rugged mountain road can effectively disperse the pressure brought to the branch pipes and can further provide a buffering force for the saddle and the whole frame to achieve a damping effect due to the restoring force and elastic force of the springs A; and meanwhile, the overall quality of the frame is improved, and the service life of the frame is greatly prolonged.

Description

technical field [0001] The invention relates to a shock-absorbing bicycle frame. Background technique [0002] Bicycles are the most commonly used and simplest means of road transportation. Especially today, with the enhancement of people's awareness of environmental protection, more and more bicycles are owned and used in various countries. At the same time, the brands of bicycles are more abundant, and the manufacturing technology has also been continuously improved. In order to meet the needs of different consumer groups, bicycle manufacturers have carried out continuous technological innovation in the structure, material and function of bicycle frames. The shock absorbing buffer devices of existing frames are generally additional components and Both are installed on the basis of the riser and the seat, and the cushioning effect mainly acts on the seat, but does not have a certain effect on the buffering of the overall frame, so the shock absorption effect is poor, and th...

Problems solved by technology

[0003] The problem to be solved by the present invention is that the shock-absorbing buffer device of the existing vehicle frame is generally an additional component and is installed on the basis of the standpipe and the vehicle seat, and its cushioning effect mainly acts on the vehicle seat. The cushioning of the overall frame does not have a certain effect, so its shock absorption effect is poor, and the structure is more complicated and the cost is higher
