Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

As shown in fig. 1 to 5, a front fork assembly 1 according to the present invention includes a front fork 10, a head pipe assembly 20, a first damping member 30, and a first spring 40.

The head pipe assembly 20 is fitted over the stand pipe 101 of the front fork 10, and the head pipe assembly 20 is movable relative to the stand pipe 101 in the axial direction of the stand pipe 101. Specifically, as shown in fig. 1, the front fork 10 is connected to a front wheel in general, and the head pipe assembly 20 is connected to a handlebar, so that the front fork 10 moves together with the wheel when the wheel vibrates, and the head pipe assembly 20 and the stem pipe 101 move relative to each other in the axial direction of the stem pipe 101.

The first damping member 30 is disposed between the front fork 10 and the head tube assembly 20, one end of the first damping member 30 abuts against the front fork 10, and the other end of the first damping member 30 abuts against the head tube assembly 20. As shown in fig. 2 and 3, the first damping member 30 is sleeved on the seat tube 101, the lower end of the first damping member 30 abuts against the front fork 10, and the upper end of the first damping member 30 abuts against the head tube assembly 20. It will be appreciated that when the front fork 10 vibrates, the head tube assembly 20 moves down the stem 101, and the first damping member is compressed, and the deformation of the first damping member absorbs the vibration energy to reduce the transmission of vibration between the front fork 10 and the head tube assembly 20.

Further, as shown in fig. 2 and 3, the first spring 40 is sleeved on the first damping member 30, one end of the first spring 40 abuts against the front fork 10, the other end of the first spring 40 abuts against the head tube assembly 20, when the front fork 10 vibrates to compress the first damping member 30, along with the compression of the first damping member 30, the first damping member 30 expands in the circumferential direction to brace the first spring 40 sleeved on the first damping member 30, and in the subsequent compression process, the first damping member 30 needs to overcome the friction force and the binding force between the first damping member 30 and the first spring 40, so that the compression rate of the first damping member 30 can be reduced, and the relative motion between the head tube assembly 20 and the front fork 10 is smooth.

Further, after the front fork 10 disappears, the first damper 30 and the first spring 40 rebound, in the process, the first damper 30 retracts in the circumferential direction thereof along with the rebound of the first damper 30, and the rebound of the first damper 30 needs to overcome the friction force between the first damper 30 and the first spring 40 before the tension force between the first damper 30 and the first spring 40 disappears, so that the rebound rate of the first damper 30 can be slowed down, thereby enabling the relatively gentle rise of the head pipe assembly.

And when there is a tension force between the first damping member 30 and the first spring 40, the first spring 40 can no longer compress or rebound in a normal direction (the "normal direction" can be understood as the moving direction of the first spring 40 when being compressed without the first damping member 30 tensioning the first spring 40), thereby further slowing down the compression and rebound speed of the first spring 40.

In some embodiments, as shown in fig. 2 and 3, the front fork assembly 1 further comprises a first stop plate 50, the first stop plate 50 is disposed on the stem 101 and located between the first damping member 30 and the head pipe assembly 20, and a surface of the first stop plate 50 facing the front fork 10 is in contact with both the first damping member 30 and the first spring 40.

As shown in fig. 3, the lower side surface of the first stopper 50 is in contact with the first damper 30 and the upper end of the first spring 40, the upper side surface of the first stopper 50 is in contact with the lower end of the head pipe assembly 20, and the first stopper 50 is a flat sheet. Thus, the first stopper piece 50 may stop the first damper 30 and the first spring 40 when the front fork 10 vibrates, so that the compression and rebound processes of the first damper 30 and the first spring 40 are stabilized. Preferably, the first damping member 30 is a polyurethane sleeve

Further, as shown in fig. 2, the front fork assembly 1 further includes a shock absorbing ring 60, and the shock absorbing ring 60 is disposed between the first damping member 30 and the first stopper 50. Thus, the damping ring 60 can absorb high-frequency small vibration transmitted by the front fork 10, so as to improve the damping effect of the front fork assembly 1. Preferably, the damping ring and the first damping member 30 are integrally formed.

Further, as shown in fig. 2, the first damping member 30 is cylindrical or prismatic and is disposed outside the vertical tube 101, the first stop plate 50 is a circular ring or a regular polygonal ring, and the shock absorbing ring 60 is a circular ring. Therefore, the front fork assembly is high in appearance uniformity and simple in overall structure. The annular damper ring 60 may surround the outer circumference of the first damper 30 to optimize the appearance of the front fork assembly 1, and the volume of the damper ring can be increased in a unit space to improve the damping capacity of the damper ring 60.

In addition, the annular first stop piece 50 can be matched with the end face of the first damping member 30, so as to improve the reliability of stopping the first damping member 30 by the first stop piece 50.

In some embodiments, as shown in fig. 2 and 3, the front fork assembly 1 further comprises a limit nut 201, the limit nut 201 is mounted on the stem 101, a limit protrusion 202 is arranged in the head pipe assembly 20, and the limit nut 201 and the limit protrusion 202 are stopped to limit the relative movement distance between the head pipe assembly 20 and the stem 101.

As shown in fig. 3, a limit nut 201 is installed at the upper end of the stand pipe 101, when the inner circumferential surface of the head pipe assembly 20 has a limit protrusion 202, and the front fork 10 is in a non-vibration state, the limit nut 201 abuts against the end surface of the limit protrusion 202, when the front fork 10 vibrates to cause the head pipe assembly 20 to move downward relative to the stand pipe 101, the first damping member 30 and the first spring 40 are compressed, the limit protrusion 202 moves downward along with the head pipe assembly 20, the limit nut 201 is separated from the limit protrusion 202, after the front fork 10 vibrates, the first damping member 30 and the first spring 40 rebound to drive the head pipe assembly 20 to move upward relative to the stand pipe 101, and after the head pipe assembly 20 moves to the preset position, the limit nut 201 abuts against the end surface of the limit protrusion 202 again to prevent the head pipe assembly 20 from having a reset deviation.

In some embodiments, as shown in fig. 2 and 3, the standpipe 101 has an annular protrusion 1011, and the first damping member 30 wraps around the annular protrusion 1011. Thus, the first damping member 30 needs to overcome the resistance of the annular protrusion 1011 to the first damping member 30 during both compression and rebound, thereby reducing the compression and rebound velocity of the first damping member 30 and reducing the rate of movement of the head pipe assembly 20 relative to the seat pipe 101.

Further, as shown in fig. 2, the annular projection 1011 has opposite first and second annular end surfaces in the extending direction of the guide bar 211, the first annular end surface extending obliquely downward in the radial direction of the guide bar 211, and the second annular end surface extending obliquely upward in the radial direction of the guide bar 211. Therefore, the inclined and extended annular end surface can guide the deformation process of the first damping member 30, and the phenomenon of local deformation or blocking is avoided.

Further, the inclination angle of the first annular end surface is larger than that of the second annular end surface. Thus, during rebound of the first damping member 30, the annular protrusion 1011 provides a greater resistance, i.e., a slower rebound velocity than the first damping member 30 at the compression velocity, avoiding rapid rebound.

As shown in fig. 1, 4 and 5, the rear fork assembly 2 according to the embodiment of the present invention includes a rear fork 21, a second damping member 23 and a second spring 24. Specifically, as shown in fig. 4 and 5, a guide rod 211 is disposed on the rear fork 21, the second damping member 23 is sleeved on the guide rod 211, the second spring 24 is sleeved on the second damping member 23, the limiting member 25 is connected to an end of the guide rod 211, and the limiting member 25 is in contact with both the second damping member 23 and an end of the second spring 24 far away from the rear fork 21.

Specifically, the rear fork assembly 2 can be vertical and horizontal, and when the rear fork assembly 2 is vertical, reference is made to the structure and the movement process of the front fork assembly 1, which are not described herein again.

When the rear fork assembly 2 is horizontal, as shown in fig. 1 and 4, the rear fork assembly 2 includes a catch plate 22, the rear fork 21 is rotatably connected to the catch plate 22, a portion of the rear fork 21 is located in the catch plate 22, one end of a guide rod 211 is connected to the rear fork 21, the other end of the guide rod 211 extends out of the catch plate 22, a limiting member 25 is connected to the other end of the guide rod 211, and the second damping member 23 and the second spring 24 are located between the limiting member 25 and the catch plate 22.

When the rear fork 21 vibrates, the rear fork 21 is rotatable in a vertical plane to drive the guide rod 211 to move toward a direction close to the rear fork 21, the stopper 25 moves together with the guide rod 211 toward a direction close to the rear fork 21 to compress the second damping member and the second spring 24, and during the compression, the second damping member 23 expands in a circumferential direction thereof to tighten the second spring 24, so that the second spring 24 is compressed and rebounded slowly.

Further, the position-limiting member 25 includes a preload member 251 and a second stop tab 252, the second stop tab 252 stops against the second damping member 23 and the end of the second spring 24 away from the rear fork 21, and the preload member 251 passes through the second stop tab 252 and is screwed into the guide rod 211.

Thus, the preload of the second damping member 23 and the second spring 24 can be adjusted by adjusting the screwing depth of the preload member 251 according to the shock absorbing requirement of the rear fork assembly 2.

Further, the second damping member 23 may also be provided with a damping ring 60 to absorb small amplitude high frequency vibration.
