Embodiment 1

[0053] Embodiment one: for the embodiment in the bicycle frame of short four-link structure:

[0054] Front frame 100 comprises standpipe 110, upper pipe 120, downtube 130 and bottom bracket 140, bottom bracket 140 is positioned at the lower end of standpipe 110 and downtube 130 and connects standpipe 110 and downtube 130, makes standpipe 110 1. The upper tube 120 and the lower tube 130 form a stable triangular structure;

[0055] The rear vehicle frame 200 is a triangular shape, and the rear vehicle frame 200 is provided with three fulcrums. The fulcrums are the upper fulcrum 210 at the upper position and the lower fulcrum 220 at the lower position respectively, and the lower fulcrum 220 is close to the bottom bracket 140 of the front frame 100;

[0056] Both ends and the middle position of the first active lever 310 are provided with hinge points 350, one end of the first active lever 310 is one of the hinge points 350, which is hinged on the upper fulcrum 210 of the rear v...

Abstract

The invention belongs to the technical field of bicycles, and in particular relates to a bicycle and an adjustable frame damping structure thereof. It is installed on the front frame and the rear frame, and it includes a shock absorption system and an adjustment device set on the shock absorption system. The adjustment device adjusts the position of the shock absorption system on the front frame and the rear frame to quickly adjust the front Frame and rear frame angles to adapt the same bike to different riding requirements. The invention also relates to a bicycle using the adjustable frame damping structure.

Description

technical field [0001] The invention belongs to the technical field of bicycles, in particular to an adjustable shock-absorbing structure of a vehicle frame. The invention also relates to a bicycle using the adjustable frame damping structure. Background technique [0002] At present, the bicycle frame with the shock absorption system is used more and more widely, and there are more and more bicycle competitions all over the world. Bicycles are widely used. [0003] Bikes for different competitions have different shock absorption strokes and body angles, such as off-road Crosscountry, Enduro, Downhill, etc. [0004] Generally speaking, bicycles that focus on downhill performance have a relatively large shock absorption stroke and a relatively rearward body angle, because a large shock absorption stroke is conducive to absorbing the impact from obstacles on the road when going downhill at high speed, and is more rearward. The inclined body angle is conducive to increasing ...
