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

[0051] like Figure 1 As shown, the shock absorber 100 of this utility model embodiment includes an outer cylinder 1, an inner cylinder 2, a tube body 3, and an adjusting component 4.

[0052] The inner cylinder 2 is slidably assembled inside the outer cylinder 1. The outer cylinder 1 has a first cavity 11, and the inner cylinder 2 has a second cavity 21. For example, both the outer cylinder 1 and the inner cylinder 2 can be generally 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 top port of the outer cylinder 1, and the inner cylinder 2 can slide freely in the vertical direction relative to the outer cylinder 1.

[0053] The inner space of the outer cylinder 1 can form a first cavity 11, and the inner space of the inner cylinder 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-absorbing oil, and during use, the first cavity 11 and the second cavity 21 are relatively independent.

[0054] The tube body 3 is located 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 to allow the damping fluid to flow back and forth between the first cavity 11 and the second cavity 21 when the inner cylinder 2 slides relative to the outer cylinder 1.

[0055] For example, such as Figure 1 As shown, the tube body 3 can be generally tubular, specifically a cylindrical tube. The tube body 3 can be installed inside the outer cylinder 1, and the bottom end of the tube body 3 can be connected and fixed to the outer cylinder 1. 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 cylinder 2 and extend into the inner cylinder 2.

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

[0057] The adjusting element 4 is located on the pipe body 3 and its position relative to the pipe body 3 is adjustable. The adjusting element 4 is used to adjust the flow area of ​​the flow channel. For example, the adjusting element 4 can be a valve or other structure, and the adjusting element 4 can be driven by electromagnetic means. In use, the flow area of ​​the flow channel can be adjusted by adjusting the relative position of the adjusting element 4, thereby adjusting the overall support of the shock absorber 100.

[0058] Specifically, in this embodiment, the adjusting member 4 can be disposed inside 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.

[0059] For example, such as Figure 1 As shown, the adjusting component 4 can be a tubular structure. The adjusting component 4 can be installed inside the flow channel of the tube body 3 and can slide up and down relative to the tube body 3. In use, the adjusting component 4 can be moved relative to the tube body 3 by manual control. The moving tube body 3 can partially block the flow channel, thereby reducing the flow area of ​​the flow channel. This can prevent the flow velocity of the liquid in the first chamber 11 and the second chamber 21, thereby enhancing the support of the shock absorber 100.

[0060] The shock absorber 100 of this utility model embodiment can improve support when the vehicle brakes, avoiding the situation where the front of the vehicle sinks instantly due to emergency braking. It realizes instantaneous self-adjustment of support, improving the comfort and safety of vehicle driving. 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.

[0061] In some embodiments, the shock absorber 100 includes a first elastic element 5, which is disposed between the tube body 3 and the adjusting element 4, and the elastic element is used to reset the adjusting element 4 to release the obstruction effect of the adjusting element 4 on the flow channel.

[0062] For example, such as Figure 1 and Figure 2 As shown, the first elastic element 5 can be a spring. The first elastic element 5 can be installed at the bottom of the tube body 3, and the bottom end of the first elastic element 5 can abut against the tube body 3, while the top end of the first elastic element 5 can abut against the adjusting element 4.

[0063] In use, the adjusting component 4 can be manually controlled to move downward and partially block the flow channel. When the downward driving of the adjusting component 4 is released, the adjusting component 4 can move upward and reset itself under the action of the first elastic element 5, thereby realizing the self-reset of the adjusting component 4. This prevents the adjusting component 4 from blocking the flow channel during riding, ensuring the comfort of the shock absorber 100 shock absorption adjustment during riding.

[0064] In some embodiments, such as Figure 1 and Figure 2 As shown, the shock absorber 100 includes a connecting pipe 6, which is disposed within the second cavity 21. An adjusting member 4 is slidably assembled within the pipe body 3. The pipe body 3 has an adjusting cavity 34 located at one end of the adjusting member 4. For example, as shown... Figure 3 As shown, the adjustment cavity 34 can be located at the top of the tube body 3, the adjustment cavity 34 can be located above the adjustment member 4, and the adjustment cavity 34 is a relatively sealed chamber.

[0065] One end of the connecting pipe 6 is connected to the brake fluid circuit 500 for conveying brake fluid, and the other end of the connecting pipe 6 is connected to the adjustment chamber 34. The connecting pipe 6 is used to convey brake fluid into the adjustment chamber 34 to achieve the movement drive of the adjustment component 4.

[0066] For example, the top end of the connecting pipe 6 can be sealed through the top of the inner cylinder 2 and connected to the brake fluid circuit 500, while the bottom end of the connecting pipe 6 can be sealed to the regulating chamber 34. In use, a portion of the brake fluid, such as brake oil, in the brake fluid circuit 500 can be transported to the regulating chamber 34 via the connecting pipe 6. As the brake fluid enters, the pressure inside the regulating chamber 34 increases, thereby driving the regulating member 4 to move downward, which in turn reduces the flow cross-section of the flow channel.

[0067] It should be noted that the brake fluid circuit 500 is connected to the brake lever assembly 200 during actual assembly. When operating the brake lever assembly 200, the adjustment component 4 can be driven at the same time. This realizes the linkage between braking and the support of the shock absorber 100, further improving the convenience and timeliness of operation.

[0068] In some embodiments, the tube body 3 includes a first end 32 and a tube body 31. The tube body 31 passes through the inner cylinder 2, and one end of the tube body 31 is connected to the outer cylinder 1. The first end 32 is located inside the inner cylinder 2 and is connected to the other end of the tube body 31. The adjustment cavity 34 is located inside the first end 32.

[0069] For example, such as Figure 2 and Figure 3 As shown, the tube body 31 can be generally cylindrical, and the first end 32 can be an annular structure. The tube body 31 is located inside 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 32. Part of the internal space of the first end 32 can form the aforementioned adjustment cavity 34.

[0070] Thus, on the one hand, it facilitates the formation of the adjustment cavity 34, and on the other hand, the first end 32 can also be supported by the inner circumferential wall of the inner cylinder 2, that is, the inner cylinder 2 can be limited between the first end 32 and the outer cylinder 1, thereby enhancing the stability of the inner cylinder 2 sliding relative to the outer cylinder 1.

[0071] In some embodiments, such as Figure 2 and Figure 5 As shown, the pipe body 31 is provided with a first hole 311. The first hole 311 can be provided on the pipe wall at the bottom end of the pipe body 31. The first hole 311 connects the first cavity 11 and the inner cavity of the pipe body 3, as shown. Figure 2 and Figure 3 As shown, the first end 32 is provided with a second hole 321, which connects the second cavity 21 and the inner cavity of the tube body 3.

[0072] The adjusting component 4 is tubular, and the first hole 311, the second hole 321, and the inner hole 43 of the adjusting component 4 form a flow channel. That is, when riding, the damping fluid in the first chamber 11 and the second chamber 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 component 4, thereby facilitating the formation of the flow channel.

[0073] In some embodiments, a groove 322 is provided on the outer peripheral side of the first end 32. The groove 322 extends along the axial direction of the inner cylinder 2 and passes through the first end 32, and the groove 322 connects the second cavity 21 and the second hole 321.

[0074] For example, such as Figure 4 As shown, the groove 322 can be a rectangular groove, and the groove 322 can extend through the first end 32 in the vertical direction. The opening at the outer end of the second hole 321 can be located on the bottom wall of the groove 322. When the inner cylinder 2 retracts into the outer cylinder 1, the damping fluid in the first cavity 11 can flow into the groove 322 through the second hole 321, and then 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 cylinder 2 abutting against each other is satisfied, as well as the design requirement of connecting the first cavity 11 and the second cavity 21.

[0075] In some embodiments, such as Figure 4 As shown, the first end 32 is provided with a plurality of second holes 321, which are arranged at intervals along the circumference of the first end 32. The outer circumference of the first end 32 is provided with a plurality of grooves 322, which are arranged at intervals along the circumference of the first end 32. The plurality of second holes 321 are respectively connected to the plurality of grooves 322.

[0076] This improves the uniformity 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 also to improving the flow efficiency of the damping fluid between the first cavity 11 and the second cavity 21.

[0077] In some embodiments, such as Figure 2As shown, the adjusting member 4 is provided with a third hole 41 and a fourth hole 42. The third hole 41 is provided at the end of the adjusting member 4 facing the first end 32, and the fourth hole 42 is provided at the end of the adjusting member 4 away from the first end 32. Specifically, the third hole 41 can be provided at the top of the adjusting member 4, and the fourth hole 42 can be provided at the bottom of the adjusting member 4.

[0078] like Figure 3 As shown, the third hole 41 connects the second hole 321 and the inner hole 43 of the adjusting member 4, as... Figure 5 As shown, the fourth hole 42 connects the first hole 311 and the inner hole 43 of the adjusting member 4. This satisfies the need for reciprocating flow of damping fluid in the first cavity 11 and the second cavity 21 via the first hole 311, the second hole 321, the third hole 41, and the fourth hole 42.

[0079] 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 ​​at least one third hole 41 is greater than the flow area of ​​at least one second hole 321.

[0080] For example, multiple second holes 321 can be provided, and multiple third holes 41 can also be provided. The total flow area of ​​multiple third holes 41 is greater than the total flow area of ​​multiple second holes 321, thereby avoiding the situation where the setting of the adjusting element 4 reduces the normal damping and comfort of the shock absorber 100, and ensuring the flow performance of the damping fluid between the inner hole 43 of the adjusting element 4 and the second cavity 21.

[0081] In some embodiments, the flow area of ​​at least one fourth hole 42 is greater than the flow area of ​​at least one first hole 311.

[0082] For example, multiple fourth holes 42 can be provided, and multiple first holes 311 can also be provided. The total flow area of ​​multiple fourth holes 42 is greater than the total flow area of ​​multiple first holes 311, thereby avoiding the situation where the setting of the adjusting component 4 reduces the normal shock absorption and comfort of the shock absorber 100, and ensuring the flow performance of the damping fluid between the first cavity 11 and the inner hole 43 of the adjusting component 4.

[0083] In some embodiments, such as Figure 3 As shown, an annular cavity 35 is provided between the tube body 3 and the adjusting member 4. The annular cavity 35 is located on the outer periphery of the adjusting member 4 and can be distributed simultaneously on the first end 32 and the tube body 31. The annular cavity 35 connects 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 less 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 vertical direction is less than the length dimension of the annular cavity 35 in the vertical direction.

[0084] 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, thus ensuring the connectivity of the flow channel.

[0085] In some embodiments, the inner cylinder 2 is provided with a second end 22, which is used to communicate with the brake fluid circuit 500, and the connecting pipe 6 is connected between the first end 32 and the second end 22.

[0086] For example, such as Figure 1 and Figure 2 As shown, the second end 22 can be located inside the inner cylinder 2 and sealed at the top of the inner cylinder 2. The top end of the connecting pipe 6 can be connected to the second end 22, and the bottom end of the connecting pipe 6 can be connected to the first end 32. Both the first end 32 and the second end 22 are provided with through holes, thereby meeting the needs of conveying brake fluid through the connecting pipe 6.

[0087] In some embodiments, the shock absorber 100 includes a second elastic member 7, which is disposed inside the inner cylinder 2 and elastically supports the first end 32 and the second end 22. The connecting pipe 6 is disposed inside the second elastic member 7 and extends spirally along the axial direction of the inner cylinder 2 and is deformable.

[0088] For example, such as Figure 1 and Figure 2 As shown, the second elastic element 7 can be a spring. The second elastic element 7 can be assembled inside the second cavity 21. The top end of the second elastic element 7 can abut against the second end 22, and the bottom end of the second elastic element 7 can abut against the first end 32. The provision of the second elastic element 7 can further enhance the shock absorption and cushioning effect of the shock absorber 100. Secondly, it also facilitates the stretching and restoring of the shock absorber 100.

[0089] The connecting pipe 6 can be a flexible hose, and the second elastic element 7 can be sleeved on the outer periphery of the connecting pipe 6. The connecting pipe 6 as a whole can be spiral-shaped and extend spirally in the up-down direction. Thus, after the inner cylinder 2 is pressed into the outer cylinder 1, the connecting pipe 6 itself will also be compressed, thereby limiting the deformation of the connecting pipe 6 and avoiding the risk of interference between the connecting pipe 6 and the second elastic element 7 due to the uncertainty of deformation.

[0090] In some embodiments, the shock absorber 100 includes a seal 9, for example, such as Figure 1 As shown, the sealing element 9 can be an annular rubber plug. The sealing element 9 is located inside the inner cylinder 2 and sleeved on the outer periphery of the tube body 3. The sealing element 9 is used to achieve a sealed isolation between the first cavity 11 and the second cavity 21. This also satisfies the need for the first cavity 11 to be squeezed by the downward displacement of the inner cylinder 2.

[0091] In some embodiments, such as 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 fitted into the annular groove on the outer periphery of the tube body 31. The sealing ring 33 can achieve the sealing between the tube body 31 and the inner peripheral wall of the inner cylinder 2, further enhancing the sealing and isolation function of the first cavity 11 and the second cavity 21.

[0092] In some embodiments, such as Figure 5 As shown, the shock absorber 100 also includes a fastener 8, which can be a bolt or the like. The fastener 8 can be threaded onto the bottom end of the outer cylinder 1. The bottom of the tube body 3 is provided with a threaded hole. The fastener 8 is threaded into the threaded hole of the tube body 3, which facilitates the fixing of the bottom of the tube body 3 and also achieves the sealing of the bottom of the tube body 3, thus improving the ease of assembly.

[0093] The following describes the brake and shock absorption linkage system according to an embodiment of the present invention.

[0094] The brake damping linkage system of this utility model embodiment includes a shock absorber, which can be the shock absorber 100 as described in any of the above embodiments.

[0095] In some embodiments, such as Figure 6 As shown, the brake damping linkage system includes a brake lever assembly 200 and a brake 300. The brake 300 is used to brake the wheels. The adjusting component 4 is driven by brake fluid. Both the brake 300 and the damper 100 are connected to the brake lever assembly 200 through a brake fluid passage 500 for supplying brake fluid.

[0096] In use, the brake lever assembly 200 can be manually held. Under the action of the brake lever assembly 200, a portion of the brake fluid can be delivered along the brake fluid passage 500 to the brake 300, thereby achieving braking. Another portion of the brake fluid can be delivered along the brake fluid passage 500 to the shock absorber 100, and then through the aforementioned connecting pipe 6 to the adjustment chamber 34, thereby driving the adjustment component 4 and adjusting the support of the shock absorber 100. This achieves linked control of braking and shock absorber 100 adjustment via the brake lever assembly 200.

[0097] In some embodiments, such as Figure 6As shown, the brake damping linkage system includes a brake lock-up system 400, which is also known as ABS. The brake fluid circuit 500 includes a main line 501, a first branch line 503, and a second branch line 502. The main line 501 connects the brake lever assembly 200 and the brake lock-up system 400. The first branch line 503 connects the brake lock-up system 400 and the brake 300. The second branch line 502 connects the brake lock-up system 400 and the shock absorber 100. Thus, the brake lock-up system 400 enables the diversion of brake fluid, simplifying the layout of the brake fluid circuit 500.

[0098] In some embodiments, the wheels are front wheels, such as... Figure 6 As shown, there are two shock absorbers 100, and the front wheel is located between the two shock absorbers 100.
