Description

Improved shock absorber seatpost

This creation is related to a shock-absorbing seat tube structure related to bicycles, especially one that provides good cushioning and shock-absorbing effects that can be adjusted according to requirements, so that users can be more comfortable when riding a bicycle, and has a simple structure and Improved shock absorber seat tube for easy maintenance.

Bicycle is a kind of commonly used means of transportation. It uses human pedaling as its power source and does not need to use electricity or gasoline. It has an environmental protection concept and is very suitable for use as a general means of transportation or a leisure sports device.

In the current environment, there are few completely flat roads, so that when the user rides a bicycle and encounters rough and uneven roads, or when climbing a mountain and driving on stone roads, roads with drop terrain, etc., the bicycle will be damaged due to The unevenness of the ground causes vibrations. In order to solve this problem, most general bicycles are equipped with shock absorbers to absorb the vibrations, so that users can feel more comfortable when riding.

Most of the shock absorbers are installed on the handlebars, front forks, rear forks and the seat tube below the seat cushion of the bicycle, and for the current shock absorber seat tube, it includes an inner tube, an outer tube and a buffer unit; The top of the tube is connected to the seat cushion; the outer tube is sleeved with the inner tube, and the bottom of the outer tube is connected to the car body; the buffer unit is pierced with the outer tube, and the two ends are respectively against the inner tube and the outer tube, thereby providing the buffer force of the inner tube; but In the current common structural configuration, the air pressure or hydraulic structure is mainly used as the buffer unit, so that in addition to increasing the complexity of the structure, there will also be a problem that it is difficult to maintain. Therefore, the practicability of the aforementioned conventional technology is not sufficient. Ideal but in need of improvement.

Therefore, such as the Republic of China Patent Announcement No. M523651, the patent name "Shock-absorbing Seat Tube for Bicycles", please refer to Figures 2 to 4 of the younger brother, which includes an outer tube, an inner tube that passes through the outer tube, A seat tube lifting element arranged in the outer tube and connected to the inner tube, and a buffer unit arranged in the inner tube, wherein the buffer unit has a first sleeve, a second sleeve, and a buffer body, The first set The seat can be screwed to the inner tube or the outer tube and has two first half seats that are connected to each other.
