[0020] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] In the description of this utility model, unless otherwise specified, "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-5 As shown, the utility model provides a technical solution: a bicycle frame with a shock-absorbing effect, comprising a seat tube 1 and a seat cushion 3, a front bracket 8 fixedly connected to one side of the outer wall of the seat tube 1, a rear bracket 2 fixedly connected to the other side of the outer wall of the seat tube 1, a telescopic tube 4 inserted into the top end of the seat tube 1, and a supporting shock-absorbing mechanism 5 provided between the seat cushion 3 and the telescopic tube 4;

[0024] The supporting shock-absorbing mechanism 5 includes a pillar 504 and an electric push rod 505. A column hole 501 is provided at the top of the telescopic tube 4. The pillar 504 is movable through the column hole 501 to penetrate the top of the telescopic tube 4. The seat cushion 3 is fixedly installed on the top of the pillar 504. A mounting groove 506 is provided at the bottom end of the inner wall of the telescopic tube 4. The electric push rod 505 is fixedly installed on the inner wall of the mounting groove 506. A top plate 507 is fixedly installed on the output end of the electric push rod 505. A spring 510 is fixedly connected between the top end of the top plate 507 and the bottom end of the pillar 504. The top plate 507 is slidably connected to the inner wall of the telescopic tube 4. A damping plate 2 515 is fixedly installed on the outer wall of the pillar 504. A damping plate 1 502 is fixedly installed on the inner wall of the telescopic tube 4. The damping plate 1 502 is fitted with the damping plate 2 515. A buffer pad 503 is fixedly installed on the top of the inner wall of the telescopic tube 4.

[0025] Specifically, the above technical solution is that when the bicycle frame with shock-absorbing effect is in use, the rider sits on the seat 3. When the bicycle travels on a bumpy road section, the seat 3 will drive the column to move downward, causing the column to compress the spring 510, and the column drives the damping plate 2 515 to generate relative motion friction with the damping plate 1 502, thereby consuming vibration energy and playing a damping role. When riders of different weights use it, the electric push rod 505 can be started, and the electric push rod 505 drives the top plate 507 to move upward, causing the top plate 507 to compress the spring 510, which can increase the basic elastic force of the spring 510, thereby adjusting the shock-absorbing strength of the seat 3, so that the bicycle can adjust the shock-absorbing strength according to riders of different weights, ensuring the comfort of riders of different weights when using it, and solving the problem that it is difficult to adjust the shock-absorbing strength of existing bicycles according to riders of different weights when using them, resulting in different comfort for people of different weights when using the bicycle, thereby affecting the riding experience of the people.

[0029] Among them, by providing the damping plate 1 502 and the damping plate 2 515, the friction between the support 504 and the inner wall of the telescopic tube 4 can be increased, thereby improving the damping effect.
