TECHNICAL FIELD
[0001] The utility model belongs to bicycle seat cushion technical field, concretely relates to a bicycle seat cushion support. BACKGROUND
[0002] The conventional bicycle seat cushion support has many limitations in practical application. In terms of height adjustment, the mode is relatively single, and most of them are limited level adjustment mechanism. Taking the common quick-release seat cushion rod as an example, it can only be fixed at the preset slot position, and cannot accurately meet the individualized needs of different riders for the height of the seat cushion. Neither adults and children with significant height difference nor professional riders with high requirements for riding experience can obtain the most appropriate seat cushion height through such an adjustment mode. When dealing with bumpy roads, the damping and buffering performance of the existing seat cushion support is obviously insufficient. Most conventional supports are designed with rigid structure and lack effective damping components. When the bicycle passes through uneven roads such as potholes and speed bumps, the vibration will be directly and unbuffered transmitted to the seat cushion, causing the rider's hips to bear a large impact. After a long time of riding, not only will it cause the hips to feel sore, but it may also cause discomfort in the rider's waist, back and other parts, thereby significantly reducing the comfort of riding.

[0031] Working principle:
[0032] The bicycle cushion support, when the rider needs to adjust the height of the cushion 16, drives the connecting shaft 4 and the driving bevel gear 5 to rotate through the rotating disc 3, drives the adjusting shaft 6 to rotate through the driven bevel gear 7, and then drives the adjusting column 8 to move in the supporting pipe 1, adjusts the height of the cushion 16, moves the cushion 16 to the appropriate height, and then tightens the fixing bolt on the fixing ring 2, fixes the position of the rotating disc 3.
[0033] When the bicycle runs on uneven road and is vibrated, the elastic shock column 10 and the shock absorbing spring 11 will be elastically deformed, and a part of vibration energy is absorbed through the elastic deformation of the elastic shock column 10, and at the same time, the elastic shock column 10 is internally provided with a damping liquid filling chamber, and in the process of deformation of the elastic shock column 10, the damping liquid flows in the chamber, and the flow of the damping liquid produces a certain resistance, which can further consume vibration energy, effectively absorbs and buffers the vibration transmitted to the bicycle from the road, reduces the amplitude of the vibration transmitted to the cushion 16, and significantly improves the comfort of riding.
[0034] When the angle of the cushion 16 needs to be adjusted, the fixed pin 18 is pulled to separate the fixed pin 18 from the connecting block 15, the connecting block 15 is rotated, the angle of the cushion 16 is adjusted, the fixed pin 18 is released after the angle adjustment of the cushion 16 is completed, the fixed spring 20 supports the positioning ring 19, and the fixed pin 18 is inserted into the fixed hole of the connecting block 15, so that the position of the cushion 16 is fixed.
