Abstract

A bicycle frame with a shock-absorbing mechanism comprises a front triangle, a rear triangle and a middle axis assembly which rotatably connects the front triangle with the rear triangle. The front triangle consists of a middle tube, a front tube and a connecting tube which is respectively connected and fixed to the front tube and the middle tube at both ends. The rear triangle is rotatably connected to the middle part of the connecting tube through the middle axis assembly. The bottom end of the middle tube is supported on a fixed surface of the rear triangle by a shock-absorbing material. The upper end of the material is fixed to the bottom end of the middle tube by a clamping ring, and the lower end of the material is supported on the fixed surface of the rear triangle. A limiting mechanism which limits the amplitude of the middle tube's jumping is provided between the clamping ring and the fixed surface of the rear triangle. The present invention provides a bicycle frame with a shock-absorbing mechanism, which has a simple structure, good shock-absorbing effect and is easy to install.

Description

Technical Field

[0001] The invention relates to the technical field of bicycles, in particular to a bicycle frame with a shock-absorbing mechanism. Background Art

[0002] With the continuous development of bicycles, bicycles are not only used as a means of transportation for travel, but also become a favorite leisure sports device, or use bicycles to participate in related competitions. Therefore, bicycles have been widely popularized, and riders pay more and more attention to the performance and riding experience of bicycles during riding. Therefore, bicycles are constantly innovated and improved in structure, especially for bicycle vibration caused by uneven ground during riding, various shock absorption schemes are adopted, such as installing a shock absorption mechanism on the front fork of the bicycle, or installing a shock absorption mechanism on the seat or the seat rod. At present, the shock absorption mechanism mainly uses a compression spring assembly, which reduces the impact of the vibration of the front and rear wheels on the rider, and improves the riding comfort and riding experience during riding. However, the current shock absorption is mainly to install the shock absorption mechanism on the pipe fittings that transmit vibration of the existing bicycle frame, and no necessary improvement is made to the existing bicycle frame. Summary of the invention

[0003] In order to make up for the above shortcomings, the present invention provides a bicycle frame with a shock-absorbing mechanism. The bottom end of the middle tube of the frame is supported on the corresponding fixed surface of the rear triangle through the shock-absorbing mechanism to achieve a shock-absorbing effect. The structure is simple and the installation is convenient and practical.

[0004] The technical solution of the present invention is achieved as follows: a bicycle frame with a shock-absorbing mechanism comprises a front triangle, a rear triangle and a middle axis assembly rotatably connecting the front triangle with the rear triangle, the front triangle is composed of a middle tube, a front tube and a connecting tube with both ends respectively connected and fixed to the front tube and the middle tube, the rear triangle is rotatably connected to the middle part of the connecting tube through the middle axis assembly, and the bottom end of the middle tube is supported on the fixed surface of the rear triangle through the shock-absorbing mechanism.

[0005] As a further improvement of the present invention, the shock-absorbing mechanism is a shock-absorbing material piece, the upper end of the material piece is fixed to the bottom end of the middle tube through a clamping ring, and the lower end of the material piece is supported on the fixing surface of the rear tripod.

[0006] As a further improvement of the present invention, a limiting mechanism for limiting the jumping amplitude of the middle tube is provided between the clamping ring and the rear tripod fixing surface. The limiting mechanism includes a limiting groove provided on the clamping ring, and also includes a limiting strip with one end fixed to the rear tripod fixing surface and the other end always inserted into the limiting groove, and one end of the limiting strip is in a T-structure, so as to facilitate limiting the middle tube to the rear tripod fixing surface through the clamping ring.

[0007] As a further improvement of the present invention, one end of the limiting strip is fixed to the fixing surface by means of screws and a set of washers, so as to facilitate the adjustment of the height of the limiting mechanism.

[0008] The beneficial technical effect of the present invention is that the front triangle in the bicycle frame with a shock-absorbing mechanism is composed of a middle tube, a front tube and a connecting tube whose two ends are respectively connected and fixed to the front tube and the middle tube; the rear triangle is rotatably connected to the middle part of the connecting tube through the middle axis assembly; the bottom end of the middle tube is supported on the fixed surface of the rear triangle through the shock-absorbing mechanism; the shock-absorbing mechanism is a material piece with shock-absorbing function; the upper end of the material piece is fixed to the bottom end of the middle tube through a clamping ring, and the lower end of the material piece is supported on the fixed surface of the rear triangle; thus, the design structure is simple and the installation is convenient.

[0009] Furthermore, a limiting mechanism for limiting the vibration amplitude of the middle tube is provided between the clamping ring and the rear tripod fixing surface. The limiting mechanism includes a limiting groove provided on the clamping ring, and a limiting strip with one end fixed to the rear tripod fixing surface and the other end always inserted into the limiting groove. One end of the limiting strip is in a T-structure, which is convenient for limiting the middle tube to the rear tripod fixing surface through the clamping ring. One end of the limiting strip can also be fixed to the fixing surface by screws and a group of washers, which is convenient for adjusting the height of the limiting mechanism. In this way, not only the vibration of the middle tube can be limited, but also the vibration amplitude can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , make the following detailed statement:

[0023] A bicycle frame with a shock-absorbing mechanism (such as Figure 1 and Figure 2 As shown), it includes a front tripod, a rear tripod and a middle axis assembly that rotatably connects the front tripod and the rear tripod, and is characterized in that the front tripod is composed of a middle tube 1, a front tube 2 and a connecting tube 3 that is respectively connected and fixed to the front tube 2 and the middle tube 1 at both ends, and the rear tripod is rotatably connected to the middle part of the connecting tube 3 through the middle axis assembly 5, and the bottom end of the middle tube 1 is supported on the fixed surface 4 of the rear tripod through a shock-absorbing mechanism.

[0024] like Figure 3 As shown, the shock-absorbing mechanism 6 is a shock-absorbing material piece 62 , the upper end of which is fixed to the bottom end of the middle tube 1 through a clamping ring 61 , and the lower end of which is supported on the rear tripod fixing surface 4 .

[0025] In order to limit the vibration amplitude of the center tube and ensure the safety of the rider, such as 3 and Figure 4 As shown, a limiting mechanism for limiting the jumping amplitude of the middle tube 1 is provided between the clamping ring 61 and the rear tripod fixing surface 4. The limiting mechanism includes a limiting groove 611 provided on the clamping ring 61, and also includes a limiting strip 63 with one end fixed to the rear tripod fixing surface 4 and the other end always inserted into the limiting groove 611, and one end of the limiting strip 63 is in a T-structure, so that the middle tube 1 can be limited to the rear tripod fixing surface 4 through the clamping ring 61.

[0026] In order to adjust the vibration amplitude of the middle tube, it is beneficial for the rider to obtain a suitable vibration range, such as Figure 5 As shown, one end of the limit strip 63 is fixed to the fixed surface by screws and a set of washers 64, so as to facilitate the adjustment of the height of the limit mechanism. In this way, according to the actual riding conditions, the rider can adjust the vibration amplitude of the middle tube by adding or reducing washers.
