Description

Technical Field

[0001] The invention relates to the technical field of bicycle frames, and more particularly to a hidden micro-shock-absorbing frame. Background Art

[0002] The bicycle frame is the skeleton and main body of the bicycle and is the basic structure of the bicycle. It connects various components and bears the weight of the rider and cargo. The frame, as the skeleton of the entire bicycle, determines and affects the correctness and comfort of the riding posture to the greatest extent. The frame components are the basic structure of the bicycle and are also the skeleton and main body of the bicycle. Other components are also directly or indirectly installed on the frame.

[0003] With the popularity of bicycles, traditional four-link soft-tail and hard-tail mountain bikes can no longer meet the needs of different groups of people. This demand requires: no four-link assembly and maintenance, but shock absorption function; hard-tail mountain bikes do not have shock absorption function, and the assembly and maintenance of four-link soft-tail bikes are too expensive and complicated; therefore, traditional four-link soft-tail and hard-tail mountain bikes are not convenient for taking into account both low-cost maintenance and shock absorption function. In view of this, we propose a hidden micro-suspension frame. Summary of the invention

[0004] The purpose of the present invention is to provide a hidden micro-shock-absorbing frame to solve the technical problem that traditional four-link soft-tail bicycles and hard-tail mountain bikes are not convenient for taking into account both low-cost maintenance and shock-absorbing functions.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a hidden micro-shock-absorbing frame, comprising a main frame beam with an axle seat formed at one end;

[0006] The end of the axle seat away from the main frame beam is symmetrically structured to form a flexible rear lower fork arm, the flexible rear lower fork arm can be elastically bent and deformed, and the end of the flexible rear lower fork arm away from the axle seat is bent upward to form a flexible rear upper fork arm, the flexible rear upper fork arm can be elastically bent and deformed, and the end of the flexible rear upper fork arm away from the flexible rear lower fork arm is connected to form a mounting seat, the end of the main frame beam away from the axle seat is connected to the head tube, the outer surface of the head tube is formed with an upper connecting rod on the top of one side facing the flexible rear upper fork arm, and a section of the upper connecting rod away from the head tube is provided with a mounting groove;

[0007] The top of the mounting seat is symmetrically structured to form a U-shaped plate, and a damping structure for alleviating rebound vibration is detachably installed between the mounting grooves.

[0008] The present invention designs a flexible rear lower wishbone and a flexible rear upper wishbone. When a vehicle encounters vibration during driving, the flexible rear lower wishbone and the flexible rear upper wishbone are deformed to absorb the vibration, and the mounting seat and the U-shaped plate are pushed to move, so that the damping structure contracts, thereby absorbing the vibration. During the rebound process of the flexible rear lower wishbone and the flexible rear upper wishbone, the vibration during the rebound is alleviated by slowly releasing the damping structure, thereby achieving shock absorption. No four-link assembly and maintenance are required, which is beneficial to reducing maintenance costs while taking into account good shock absorption characteristics.

[0009] Preferably, the damping structure includes symmetrically arranged damping bearings, which are detachably connected to the ends of the mounting grooves, and a rebound damping rod is movably arranged between the damping bearings, and a damping groove is formed inside the damping bearings for the rebound damping rod to movably extend and retract.

[0010] Preferably, the damping structure further comprises a movable shaft detachably arranged between the U-shaped plates, a through hole is formed inside the movable shaft for one end of the rebound damping rod to pass through, and one end of the rebound damping rod passes through the through hole and is fixedly connected to the movable shaft.

[0011] Preferably, rotation holes are formed on both sides of the movable shaft, and gaskets are provided on the opposite sides of the symmetrically arranged U-shaped plates at positions corresponding to the rotation holes, and a locking bolt is provided on the side of the gasket away from the U-shaped plate, and one end of the locking bolt slides through the gasket and is screwed out of the U-shaped plate, and the end of the locking bolt that is screwed out of the U-shaped plate can be rotatably set in the rotation hole.

[0012] Preferably, a seat tube is formed on the top structure of the axle seat, and the seat tube is connected to the upper connecting rod structure. The symmetrically arranged bendable upper fork arms are respectively arranged on both sides of the seat tube and the ends extend to the mounting groove.

[0013] Preferably, the top end of the seat tube and the head tube are both hollow structures.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention designs a flexible rear lower wishbone and a flexible rear upper wishbone. When the vehicle encounters vibration during driving, the vibration is absorbed by the deformation of the flexible rear lower wishbone and the flexible rear upper wishbone, and the mounting seat and the U-shaped plate are pushed to move, so that the damping structure contracts, thereby absorbing the vibration. During the rebound process of the flexible rear lower wishbone and the flexible rear upper wishbone, the vibration during the rebound is alleviated by the slow release of the damping structure, thereby achieving shock absorption. No four-link assembly and maintenance are required, which is beneficial to reducing maintenance costs. At the same time, good shock absorption characteristics are taken into account, thereby solving the problem that traditional four-link soft-tail vehicles and hard-tail mountain bikes are not convenient for taking into account both low-cost maintenance and shock absorption functions.

[0020] In an embodiment of the present invention, the damping structure includes a symmetrically arranged damping bearing seat 11, which is detachably connected to the end of the mounting groove 5, and a rebound damping rod 10 is movably arranged between the damping bearing seats 11, and a damping groove is formed inside the damping bearing seat 11 for the rebound damping rod 10 to be movably extended and retracted. The damping structure also includes a movable shaft 9 detachably arranged between the U-shaped plates 8, and a through hole is formed inside the movable shaft 9 for one end of the rebound damping rod 10 to pass through. One end of the rebound damping rod 10 passes through the through hole and is fixedly connected to the movable shaft 9, and rotation holes are formed on both sides of the movable shaft 9.

[0021] When the locking bolt 13 is tightened, it will squeeze the gasket 12, so that the gasket 12 is compressed and deformed and generates stress, thereby achieving the purpose of locking the locking bolt 13 to prevent it from falling off.

[0022] A bearing for improving the rotation stability of the movable shaft 9 is arranged between the outer portion of one end of the locking bolt 13 extending into the rotation hole and the rotation hole.

[0023] In the embodiment of the present invention, the top structure of the axle seat is formed with a seat tube 6, which is connected to the upper connecting rod 4, and symmetrically arranged flexible upper fork arms 7 are respectively arranged on both sides of the seat tube 6 and the ends extend to the mounting groove 5.
