[0050] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0051] like Figure 1 As shown, the shock absorber 100 of the embodiment of the present invention includes an outer tube 1, an inner tube 2, a tube body 3 and an adjusting member 4.

[0052] The inner cylinder 2 is slidably assembled in the outer cylinder 1, the outer cylinder 1 is provided with a first cavity 11, and the inner cylinder 2 is provided with a second cavity 21. For example, the outer cylinder 1 and the inner cylinder 2 can both be substantially cylindrical structures, wherein the radial dimension of the inner cylinder 2 is smaller than the radial dimension of the outer cylinder 1, the inner cylinder 2 can be inserted into the outer cylinder 1 from the port at the top of the outer cylinder 1, and the inner cylinder 2 can freely slide in the up and down directions relative to the outer cylinder 1.

[0053] The internal space of the outer tube 1 can form a first cavity 11, and the internal space of the inner tube 2 can form a second cavity 21. Both the first cavity 11 and the second cavity 21 are used to store liquids such as shock absorber oil, and during use, the first cavity 11 and the second cavity 21 are relatively independent.

[0054] The tube body 3 is arranged in the first cavity 11 and extends into the second cavity 21. The tube body 3 is provided with a flow channel connecting the first cavity 11 and the second cavity 21. The flow channel is used for allowing the shock absorber fluid to flow back and forth between the first cavity 11 and the second cavity 21 when the inner tube 2 slides relative to the outer tube 1.

[0055] For example, Figure 1 As shown, the tube body 3 can be generally a tubular structure, specifically a round tube, and the tube body 3 can be installed in the outer tube 1. The bottom end of the tube body 3 can be connected and fixed to the outer tube 1, and the bottom end of the tube body 3 can be closed. The top end of the tube body 3 can pass through the bottom end of the inner tube 2 and extend into the inner tube 2.

[0056] A flow channel is provided on the tube body 3, and the flow channel can be formed by the inner cavity of the tube body 3 and the through hole provided on the tube wall of the tube body 3. When in use, the first cavity 11 and the second cavity 21 can be connected through the flow channel, so that when the inner tube 2 retracts into the outer tube 1, the liquid in the first cavity 11 can flow into the second cavity 21 through the flow channel, and when the inner tube 2 is pulled out from the outer tube 1, the liquid in the second cavity 21 can flow into the first cavity 11 through the flow channel, thereby achieving a shock-absorbing effect.

[0057] The adjusting member 4 is disposed in the tube body 3 and is movable relative to the tube body 3 . When the vehicle brakes, the adjusting member 4 moves relative to the tube body 3 and reduces the flow area of ​​the flow channel to enhance the support of the shock absorber 100 .

[0058] For example, Figure 1As shown, the adjusting member 4 can be a tubular structure, and the adjusting member 4 can be assembled in the flow channel of the tube body 3 and can slide up and down relative to the tube body 3. When in use, the adjusting member 4 can be driven to move relative to the tube body 3 by manual control, and the moving tube body 3 can achieve partial blocking of the flow channel, thereby reducing the flow area of ​​the flow channel, so that the flow speed of the liquid in the first cavity 11 and the second cavity 21 can be prevented, and then the support of the shock absorber 100 can be enhanced.

[0059] The shock absorber 100 of the embodiment of the present invention can improve the support when the vehicle brakes, avoid the situation that the front of the vehicle sinks instantly due to emergency braking, realize the instantaneous self-adjustment of the support, and improve the comfort and safety of the vehicle. Secondly, since the adjustment of the support of the shock absorber 100 and the braking are carried out simultaneously, the linkage control between the two is also realized.

[0060] In some embodiments, the shock absorber 100 includes a first elastic member 5 , which is disposed between the tube body 3 and the adjusting member 4 , and is used to reset the adjusting member 4 to release the flow-blocking effect of the adjusting member 4 on the flow channel.

[0061] For example, Figure 1 and Figure 2 As shown, the first elastic member 5 can be a spring, the first elastic member 5 can be installed at the bottom of the tube body 3, and the bottom end of the first elastic member 5 can abut against the tube body 3, and the top end of the first elastic member 5 can abut against the adjusting member 4.

[0062] When in use, the adjusting member 4 can be moved downward by manual control and partially block the flow channel. When the downward drive of the adjusting member 4 is released, the adjusting member 4 can move upward and reset itself under the action of the first elastic member 5, thereby realizing self-reset of the adjusting member 4, so that the adjusting member 4 can be prevented from blocking the flow channel in the riding state, thereby ensuring the comfort of the shock absorption adjustment of the shock absorber 100 in the riding state.

[0063] In some embodiments, Figure 1 and Figure 2 As shown, the shock absorber 100 includes a connecting pipe 6, which is disposed in the second cavity 21, and an adjusting member 4 is slidably mounted in the tube body 3. The tube body 3 is provided with an adjusting cavity 34 located at one end of the adjusting member 4, for example, Figure 3 As shown, the regulating chamber 34 can be arranged at the top of the tube body 3, the regulating chamber 34 can be located above the regulating member 4, and the regulating chamber 34 is a relatively sealed chamber.

[0064] One end of the connecting tube 6 is connected to the brake fluid path 500 for conveying brake fluid, and the other end of the connecting tube 6 is connected to the regulating chamber 34 . The connecting tube 6 is used to convey brake fluid into the regulating chamber 34 to realize the movement drive of the regulating member 4 .

[0065] For example, the top end of the connecting tube 6 can be sealed and passed through the top of the inner tube 2 and communicated with the brake fluid path 500, and the bottom end of the connecting tube 6 can be sealed and communicated with the regulating chamber 34. When in use, a portion of the brake fluid such as brake oil in the brake fluid path 500 can be transported to the regulating chamber 34 through the connecting tube 6. As the brake fluid enters, the pressure in the regulating chamber 34 will increase, thereby driving the regulating member 4 to move downward, thereby reducing the flow cross section of the flow channel.

[0066] It should be noted that the brake fluid circuit 500 will be connected to the brake handle assembly 200 during actual assembly. When the brake handle assembly 200 is operated, the adjusting member 4 can be driven at the same time, thereby realizing the supporting linkage between the brake and the adjusting shock absorber 100, further improving the convenience and timeliness of the operation.

[0067] In some embodiments, the tube body 3 includes a first end cap 32 and a tube body 31, the tube body 31 passes through the inner tube 2, one end of the tube body 31 is connected to the outer tube 1, the first end cap 32 is disposed in the inner tube 2 and connected to the other end of the tube body 31, and the regulating chamber 34 is disposed in the first end cap 32.

[0068] For example, Figure 2 and Figure 3 As shown, the tube body 31 can be generally in the shape of a circular tube, the first end head 32 can be in the shape of a circular ring as a whole, the tube body 31 is arranged in the first cavity 11, the bottom end of the tube body 31 can be connected and fixed to the outer cylinder 1, and the top end of the tube body 31 can be connected and fixed to the first end head 32. Part of the internal space of the first end head 32 can form the above-mentioned adjustment cavity 34.

[0069] Therefore, on the one hand, the formation of the adjustment chamber 34 is facilitated, and on the other hand, the first end head 32 can also be supported by the inner circumferential wall of the inner tube 2, that is, the inner tube 2 can be limited between the first end head 32 and the outer tube 1, thereby enhancing the sliding stability of the inner tube 2 relative to the outer tube 1.

[0070] In some embodiments, Figure 2 and Figure 5 As shown, the tube body 31 is provided with a first hole 311, and the first hole 311 can be provided on the tube wall at the bottom end of the tube body 31, and the first hole 311 communicates with the first cavity 11 and the inner cavity of the tube body 3, as shown in FIG. Figure 2 and Figure 3 As shown, the first end 32 is provided with a second hole 321 , and the second hole 321 communicates with the second cavity 21 and the inner cavity of the tube body 3 .

[0071] The adjusting member 4 is tubular, and the first hole 311, the second hole 321, and the inner hole 43 of the adjusting member 4 form a flow channel, that is, when riding, the shock absorber fluid in the first cavity 11 and the second cavity 21 can flow back and forth between the two through the first hole 311, the second hole 321, and the inner hole 43 of the adjusting member 4, thereby facilitating the formation of the flow channel.

[0072] In some embodiments, a groove 322 is provided on the outer circumference of the first end head 32 , the groove 322 extends along the axial direction of the inner tube 2 and penetrates the first end head 32 , and the groove 322 communicates between the second cavity 21 and the second hole 321 .

[0073] For example, Figure 4 As shown, the groove 322 may be a rectangular groove, and the groove 322 may pass through the first end 32 in the up-down direction, and the orifice of the outer end of the second hole 321 may be provided on the groove bottom wall of the groove 322. When the inner tube 2 retracts into the outer tube 1, the shock absorbing fluid in the first cavity 11 may flow into the groove 322 through the second hole 321, and then may flow into the second cavity 21 through the groove 322. Thus, the assembly requirement of the first end 32 and the inner wall of the inner tube 2 being in abutment contact is met, and the design requirement of connecting the first cavity 11 and the second cavity 21 is also met.

[0074] In some embodiments, Figure 4 As shown, the first end head 32 is provided with a plurality of second holes 321, which are arranged at intervals along the circumference of the first end head 32, and a plurality of grooves 322 are provided on the outer peripheral side of the first end head 32, which are arranged at intervals along the circumference of the first end head 32, and the plurality of second holes 321 are respectively connected to the plurality of grooves 322.

[0075] This improves the balance of the circumferential flow distribution of the shock absorber 100 at the first end 32 , which is beneficial to improving the overall structural stability of the shock absorber 100 , and is also beneficial to improving the flow efficiency of the shock absorber fluid between the first chamber 11 and the second chamber 21 .

[0076] In some embodiments, Figure 2 As shown, the adjusting member 4 is provided with a third hole 41 and a fourth hole 42. The third hole 41 is provided at one end of the adjusting member 4 facing the first end 32, and the fourth hole 42 is provided at one end of the adjusting member 4 away from the first end 32. Specifically, the third hole 41 can be provided at the top end of the adjusting member 4, and the fourth hole 42 can be provided at the bottom end of the adjusting member 4.

[0077] like Figure 3 As shown, the third hole 41 is connected between the second hole 321 and the inner hole 43 of the adjusting member 4, as shown in FIG. Figure 5As shown, the fourth hole 42 is connected between the first hole 311 and the inner hole 43 of the adjusting member 4. Thus, the use requirement of realizing the reciprocating flow of the shock absorbing fluid in the first cavity 11 and the second cavity 21 through the first hole 311, the second hole 321, the third hole 41 and the fourth hole 42 is met.

[0078] In some embodiments, at least one of the first hole 311 , the second hole 321 , the third hole 41 , and the fourth hole 42 is provided, and the flow area of ​​the at least one third hole 41 is greater than the flow area of ​​the at least one second hole 321 .

[0079] For example, there may be multiple second holes 321, and there may also be multiple third holes 41. The total flow area of ​​the multiple third holes 41 is larger than the total flow area of ​​the multiple second holes 321, thereby avoiding the situation where the setting of the adjusting member 4 reduces the normal shock absorption and comfort of the shock absorber 100, and ensuring the flow performance of the shock absorber fluid between the inner hole 43 of the adjusting member 4 and the second chamber 21.

[0080] In some embodiments, a flow area of ​​the at least one fourth hole 42 is greater than a flow area of ​​the at least one first hole 311 .

[0081] For example, a plurality of fourth holes 42 may be provided, and a plurality of first holes 311 may also be provided. The total flow area of ​​the plurality of fourth holes 42 shall be larger than the total flow area of ​​the plurality of first holes 311, thereby avoiding the situation where the setting of the adjusting member 4 reduces the normal shock absorption and comfort of the shock absorber 100, and ensuring the flow performance of the shock absorber fluid between the first chamber 11 and the inner hole 43 of the adjusting member 4.

[0082] In some embodiments, Figure 3 As shown, an annular cavity 35 is provided between the tube body 3 and the adjusting member 4, and the annular cavity 35 is provided on the outer peripheral side of the adjusting member 4, and the annular cavity 35 can be distributed on the first end 32 and the tube body 31 at the same time. The annular cavity 35 is connected between the second hole 321 and the third hole 41, and the displacement stroke of the adjusting member 4 relative to the tube body 3 is smaller than the length dimension of the annular cavity 35 along the axial direction of the tube body 3, that is, the displacement stroke of the adjusting member 4 in the up-down direction is smaller than the length dimension of the annular cavity 35 in the up-down direction.

[0083] Therefore, during the up and down movement of the adjusting member 4, the third hole 41 of the adjusting member 4 can always be connected to the second hole 321 through the annular cavity 35, avoiding the situation where the third hole 41 is blocked due to the up and down movement of the adjusting member 4, thereby ensuring the connectivity of the flow channel.

[0084] In some embodiments, a second end 22 is disposed in the inner tube 2 , and the second end 22 is used to communicate with the brake fluid path 500 . The connecting pipe 6 is connected between the first end 32 and the second end 22 .

[0085] For example, Figure 1 and Figure 2 As shown, the second end 22 can be arranged in the inner tube 2 and sealed at the top of the inner tube 2. The top of the connecting tube 6 can be connected to the second end 22, and the bottom of the connecting tube 6 can be connected to the first end 32. Through holes are provided in the first end 32 and the second end 22, thereby meeting the use needs of conveying brake fluid through the connecting tube 6.

[0086] In some embodiments, the shock absorber 100 includes a second elastic member 7, which is disposed in the inner tube 2 and elastically supported between the first end 32 and the second end 22. The connecting tube 6 is disposed in the second elastic member 7, and the connecting tube 6 extends in an axial spiral along the inner tube 2 and is deformable.

[0087] For example, Figure 1 and Figure 2 As shown, the second elastic member 7 can be a spring, the second elastic member 7 can be assembled in the second cavity 21, the top end of the second elastic member 7 can abut against the second end 22, and the bottom end of the second elastic member 7 can abut against the first end 32. The provision of the second elastic member 7 can further enhance the shock absorbing and buffering effect of the shock absorber 100. Secondly, it also facilitates the stretching and resetting of the shock absorber 100.

[0088] The connecting tube 6 can be a hose, and the second elastic member 7 can be sleeved on the outer peripheral side of the connecting tube 6. The connecting tube 6 as a whole can be spiral and extend spirally in the up-down direction. Therefore, after the inner tube 2 is pressed into the outer tube 1, the connecting tube 6 itself will also be compressed, thereby limiting the deformation of the connecting tube 6 and avoiding the risk of the connecting tube 6 interfering with the second elastic member 7 due to the uncertainty of deformation.

[0089] In some embodiments, the shock absorber 100 includes a seal 9, for example, Figure 1 As shown, the seal 9 can be an annular rubber plug, which is arranged in the inner tube 2 and sleeved on the outer peripheral side of the tube body 3, and the seal 9 is used to achieve the sealing isolation between the first cavity 11 and the second cavity 21. Thus, the use requirement of squeezing the first cavity 11 by the downward displacement of the inner tube 2 is also met.

[0090] In some embodiments, Figure 2 and Figure 3 As shown, the shock absorber 100 also includes a sealing ring 33, which can be a rubber ring. The sealing ring 33 can be assembled in the annular groove on the outer peripheral side of the tube body 31. The sealing ring 33 can achieve sealing between the tube body 31 and the inner peripheral wall of the inner tube 2, further enhancing the effect of sealing and isolating the first cavity 11 and the second cavity 21.

[0091] In some embodiments, Figure 5As shown, the shock absorber 100 also includes a fastener 8, which can be a bolt or the like. The fastener 8 can be threadedly assembled on the bottom end of the outer tube 1. A threaded hole is provided at the bottom of the tube body 3, and the fastener 8 is threadedly assembled in the threaded hole of the tube body 3 at the same time, thereby facilitating the fixation of the bottom of the tube body 3, and also realizing the sealing of the bottom of the tube body 3, thereby improving the convenience of assembly.

[0092] The brake damping linkage system according to an embodiment of the present invention is described below.

[0093] The brake damping linkage system of the embodiment of the present invention includes a shock absorber, and the shock absorber may be the shock absorber 100 described in any of the above embodiments.
