[0058] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0059] As Figure 1 and Figure 7 shown, the shock absorption assembly of the embodiment of the present invention includes a front fork 1, a swing arm 2, a shock absorption component 3 and a wheel 4. Among them, the front fork 1 as a whole can be Y-shaped, and the material of the front fork 1 can be metal. As Figure 1 shown, the front fork 1 can include a pipe part 1A and a fork part 1B. The pipe part 1A can be generally circular tubular, and the pipe part 1A can be integrally formed on the top side of the fork part 1B. The fork part 1B can be generally V-shaped, and the opening of the fork part 1B can be arranged downward.

[0060] One end of the swing arm 2 is connected to the wheel 4, and a cavity 21 is provided at the other end of the swing arm 2. For example, as Figure 6 and Figure 8 shown, the swing arm 2 generally extends along the front-rear direction, and the front end of the swing arm 2 can be fixedly connected to the axle of the wheel 4. Specifically, as Figure 6 and Figure 8 shown, the front end of the swing arm can be provided with an assembly groove 23. The notch of the assembly groove 23 can be downward, and the axle of the wheel 4 can be horizontally embedded in the assembly groove 23, and the end of the axle can be locked and fixed to the swing arm 2 through a fastener 9 such as a nut.

[0061] As Figure 1 shown, the swing arm 2 generally extends along the front-rear direction, and the axial direction of the pipe part 1A of the above-mentioned front fork 1 is generally from the front lower to the rear upper direction, that is, the extension direction of the swing arm 2 and the axial direction of the pipe part 1A intersect. The fork part 1B can be connected between the pipe part 1A and the swing arm 2. Thus, during installation and arrangement, the axle of the wheel 4 can be made to be close to the axis of the pipe part 1A and generally located directly below the pipe part 1A, thereby improving the structural compactness of the assembly and also conforming to the ergonomic design, which can increase the riding comfort.

[0062] The rear end of the swing arm 2 can be integrally formed with a cavity 21 by means of casting or the like. The cavity 21 can be generally cylindrical, and the axis of the cavity 21 generally extends along the left-right direction. [[ID=4,7]]

[0063] The shock-absorbing assembly 3 includes a housing 31, a shock-absorbing member 32, and a shaft body 33. The housing 31 is non-rotatably assembled in the cavity 21. The shaft body 33 is assembled in the housing 31 and connected to the front fork 1. The shock-absorbing member 32 is assembled between the housing 31 and the shaft body 33, and the shock-absorbing member 32 can elastically deform to buffer the rotation of the rocker arm 2 and the housing 31 relative to the front fork 1 and the shaft body 33.

[0064] For example, as Figure 3 and 9 shown, the housing 31 can generally be cylindrical, the axial direction of the housing 31 can generally be the left-right direction, the material of the shock-absorbing member 32 can be a material with elastic deformation performance such as rubber, and the shock-absorbing member 32 can generally be cylindrical. The shock-absorbing member 32 can be sleeved and fixed on the outer peripheral side of the shaft body 33, and the housing 31 can be sleeved and fixed on the outer peripheral side of the shock-absorbing member 32.

[0065] During assembly, as Figure 4 shown, the housing 31 can be assembled in the cavity 21, and the housing 31 can be fixedly connected to the cavity 21, that is, the housing 31 and the cavity 21 can be regarded as an integral body and cannot rotate relative to each other. The end of the shaft body 33 can extend from the end of the housing 31 and be fixedly connected to the fork portion 1B of the front fork 1.

[0066] In the case of bumpy roads, the rocker arm 2 will swing up and down with the wheel 4, and the housing 31 will rotate synchronously with the rocker arm 2. Thus, due to the relative rotation of the housing 31 and the shaft body 33, the shock-absorbing member 32 in the housing 31 will be twisted and elastically deformed, so that the elastic deformation performance of the shock-absorbing member 32 can play a role in buffering and shock absorption.

[0067] In the shock-absorbing assembly of the embodiment of the present invention, compared with the case of spring shock absorption, the noise during the process of the shock-absorbing member 32 being twisted and squeezed is small, avoiding the situation of large noise caused by the up-and-down movement of the spring in the prior art. Secondly, the cavity 21 is integrally formed on the rocker arm 2, which can play a role in reducing the number of parts and ensuring the strength of the connection structure, and ensuring the structural stability during use. In addition, the shock-absorbing assembly 3 realizes modular design, and during assembly, the formed shock-absorbing assembly 3 can be directly assembled in the cavity 21, thereby improving the convenience of installation and subsequent maintenance.

[0068] In some embodiments, the front fork 1 includes two fork arms 11 arranged oppositely in the axial direction of the shaft body 33. One end of the shaft body 33 is fixed to one fork arm 11, and the other end of the shaft body 33 is fixed to the other fork arm 11. The housing 31 and the shock-absorbing member 32 are located between the two fork arms 1 eleven.

[0069] For example, as Figure 1 and Figure 5As shown, both of the two fork arms 11 can be in the shape of long plates. The two fork arms 11 can be arranged in parallel at intervals in the left - right direction, and the two fork arms 11 form the above - mentioned fork part 1B. During assembly, the shaft body 33 can be sandwiched between the two fork arms 11, and the left end of the shaft body 33 can be fixedly connected to the left - hand fork arm 11, and the right end of the shaft body 33 can be fixedly connected to the right - hand fork arm 11. The way of the fixed connection can be welding, screws, etc. Thus, the structural strength and stability of the assembly of the shaft body 33 and the two fork arms 11 are ensured.

[0070] In some embodiments, the shock - absorbing assembly includes end caps 5. There are two end caps 5, and both of the two end caps 5 are sleeved on the outer peripheral side of the shaft body 33. One end cap 5 is fitted between the housing 31 and one fork arm 11, and the other end cap 5 is fitted between the housing 31 and the other fork arm 11. The end cap 5 is used to abut against the end of the housing 31 to limit the axial movement of the shock - absorbing component relative to the cavity.

[0071] For example, as Figure 1 and Figure 4 shown, the end cap 5 can generally be in the shape of an annular ring. During assembly, one of the end caps 5 can be sleeved on the left end of the shaft body 33, and this end cap 5 can be located between the housing 31 and the left - hand fork arm 11 and can be in clearance fit with the housing 31 and the left - hand fork arm 11 respectively; the other end cap 5 can be sleeved on the right end of the shaft body 33, and this end cap 5 can be located between the housing 31 and the right - hand fork arm 11 and can be in clearance fit with the housing 31 and the right - hand fork arm 11 respectively.

[0072] During use, since the shaft body 33 and the housing 31 are connected by a shock - absorbing member 32 with the ability of elastic deformation, the shaft body 33 will move axially in the left - right direction relative to the housing 31, that is, the housing 31 of the shock - absorbing component will move left and right between the two fork arms 11. The setting of the end cap 5 can play a role in blocking and limiting the housing 31, and further can play a certain role in preventing the left - right movement, ensuring the stability of riding.

[0073] In some embodiments, at least part of the end cap 5 is embedded in the annular space between the multiple housings 31 and the shaft body 33. For example, as Figure 4 shown, an annular protrusion can be integrally formed on the inner side (the side for facing the housing 31) of the end cap 5. During assembly, the annular protrusion can extend into the housing 31 from the port of the housing 31, and the annular protrusion can play a role in radial limitation, further ensuring the structural stability of the assembly.

[0074] In some embodiments, the end cap 5 can be elastically deformed. For example, the end cap 5 can be processed from a material with elastic deformation properties. In some other embodiments, the end cap 5 can also have a structure similar to an elastic gasket. When the housing 31 of the shock absorption component moves between the two fork arms 11, the end cap 5 can elastically abut between the housing 31 and the corresponding fork arm 11, thereby playing a certain role in elastic buffering and damping shock absorption, and further enhancing the riding comfort.

[0075] In some embodiments, the shaft body 33 is connected to the fork arm 11 through a fixing member 6. A reinforcing block 111 is provided on the fork arm 11, and the fixing member 6 passes through the reinforcing block 111 and is connected to the shaft body 33. For example, as Figure 2 and Figure 4 shown, the fixing member 6 can be a bolt, a screw, etc. As Figure 5 shown, a reinforcing block 111 can be integrally formed at the bottom end of each fork arm 11. The reinforcing block 111 is generally in the shape of a flat cylinder, and through holes can be provided on the reinforcing block 111. As Figure 3 shown, a fixing hole 331 is provided at the end of the shaft body 33. The depth direction of the fixing hole 331 is the axial direction of the shaft body 33, and the fixing hole 331 can specifically be a threaded hole.

[0076] During assembly, the fixing member 6 can pass through the through hole on the reinforcing block 111 and be threadedly assembled with the fixing hole 331 on the shaft body 33, thus facilitating the installation and fixation of the shaft body 33 and the fork arm 11. The setting of the reinforcing block 111 ensures the structural strength of the installation position of the fixing member 6 and also meets the usage requirements of having a high shear strength during use.

[0077] In some embodiments, the shaft body 33 is connected to the fork arm 11 through a plurality of fixing members 6, and the plurality of fixing members 6 are arranged at intervals along the circumferential direction of the shaft body 33. For example, as Figure 4 shown, two fixing members 6 can be provided, and the two fixing members 6 can be arranged in parallel at intervals in the front and rear directions. In some other embodiments, the number of fixing members 6 can also be three, four, five, etc., thus fully ensuring the structural strength of the installation.

[0078] It should be noted that when a plurality of fixing members 6 are provided, as Figure 3 shown, a plurality of fixing holes 331 can be provided at the end of the shaft body 33, and the plurality of fixing members 6 can be threadedly assembled one by one in the corresponding fixing holes 331.

[0079] In some embodiments, as Figure 3 shown, a plurality of weight reduction holes 332 can also be provided on the shaft body 33. The number of weight reduction holes 332 can be the same as the number of fixing holes 331, and the plurality of weight reduction holes 332 and the plurality of fixing holes 331 can be arranged alternately one by one in the circumferential direction of the shaft body 33. Thereby, it can play a role in weight reduction and reducing consumables.

[0080] In some embodiments, the distance between at least part of the two fork arms 11 in the axial direction of the shaft body 33 gradually decreases in the direction approaching the cavity. For example, as Figure 6 shown, the two fork arms 11 can be arranged oppositely in the left - right direction. Each fork arm 11 can generally be Z - shaped, and the two fork arms 11 are generally arranged in mirror symmetry. And in the front - to - back direction, the distance between the two fork arms 11 remains unchanged first, then gradually decreases, and then remains unchanged.

[0081] Thus, on the one hand, the front - end distance between the two fork arms 11 is relatively large, meeting the usage requirement for installing the wheel. On the other hand, the rear - end distance between the two fork arms 11 is relatively small and can match the axial dimension of the cavity, so that not only the rear end of the rocker arm has high structural strength, but also it is convenient to assemble between the two fork arms 11.

[0082] In some embodiments, a plurality of openings 112 are provided on the fork arm 11. For example, as Figure 5 shown, a plurality of openings 112 can be provided on each fork arm 11. The openings 112 are through - holes and can penetrate the two fork arms 11 in the left - right direction. The openings 112 can be holes similar to triangles. Thus, it can play a role in weight reduction and reducing material consumption.

[0083] In some embodiments, the rocker arm 2 is provided with a first limiting portion 24, and the front fork 1 is provided with a second limiting portion 12. The first limiting portion 24 is used to block against the second limiting portion 12 to limit the upper limit value of the rotation angle of the rocker arm 2 relative to the front fork 1.

[0084] For example, as Figure 8 shown, the first limiting portion 24 can be integrally formed at the rear end of the rocker arm 2, specifically on the top side of the cavity 21. The first limiting portion 24 can generally be square - shaped. As Figure 10 shown, the second limiting portion 12 can be a plate - like structure and can be integrally formed on the front fork 1.

[0085] When the rocker arm 2 swings upward, the first limiting portion 24 will move backward and downward and be blocked by the second limiting portion 12. By the blocking cooperation between the first limiting portion 24 and the second limiting portion 12, it can play a role in limiting the maximum upward swing angle of the rocker arm 2 (that is, limiting the upper limit value of the rotation angle of the rocker arm 2), avoiding the problem of excessive swing amplitude of the rocker arm 2.

[0086] In some embodiments, as Figure 7As shown, the front fork 1 includes two fork arms 11 arranged oppositely in the left-right direction. The two fork arms 11 form the above-mentioned fork portion 1B. The two fork arms 11 are respectively connected to both ends of the shaft body 33. That is, the bottom end of the left fork arm 11 can be connected to the left end of the shaft body 33, and the bottom end of the right fork arm 11 can be connected to the right end of the shaft body 33.

[0087] The cavity 21 is located between the two fork arms 11. For example, the cavity 21 can abut between the two fork arms 11. The second limiting portion 12 can be provided between the two fork arms 11. For example, the second limiting portion 12 can be in a plate-like structure. The left side of the second limiting portion 12 can be fixedly connected to the left fork arm 11, and the right side of the second limiting portion 12 can be fixedly connected to the right fork arm 11. As Figure 8 shown, the first limiting portion 24 can be located at the middle position of the cavity 21 in the left-right direction. Thus, it is convenient for the limiting assembly of the first limiting portion 24 and the second limiting portion 12.

[0088] In some embodiments, the fork arm 11 is provided with an anti-rotation groove 113, and the shaft body 33 is provided with an anti-rotation portion 333. The anti-rotation portion 333 is in anti-rotation fit within the anti-rotation groove 113. For example, as Figure 7 shown, the bottom end of each fork arm 11 can be provided with an anti-rotation groove 113 with the notch facing downwards. The anti-rotation groove 113 can generally be a rectangular groove. As Figure 9 shown, the anti-rotation portion 333 can be integrally formed on the shaft body 33. The anti-rotation portion 333 can generally be a square column.

[0089] During assembly, the anti-rotation portion 333 can be horizontally inserted into the anti-rotation groove 113 from the notch of the anti-rotation groove 113. Through the blocking fit between the anti-rotation portion 333 and the groove wall of the anti-rotation groove 113, the anti-rotation assembly of the anti-rotation portion 333 and the anti-rotation groove 113 can be realized, thereby avoiding the relative rotation between the shaft body 33 and the front fork 1.

[0090] In some embodiments, the housing 31 is in interference fit within the cavity 21. Specifically, the inner diameter of the cavity 21 can be slightly smaller than the outer diameter of the housing 31. During assembly, the cavity 21 can be heated, and then the housing 31 can be directly inserted into the cavity 21. In some other embodiments, the housing 31 can also be fixedly installed to the cavity 21 by screws, bolts, etc.

[0091] In some embodiments, one of the inner peripheral wall of the cavity 21 and the outer peripheral wall of the housing 31 is provided with a protrusion 311, and the other is provided with a groove 211. The protrusion 311 is fitted within the groove 211 to realize the anti-rotation assembly of the housing 31 and the cavity 21.

[0092] For example, as Figure 11As shown, a plurality of grooves 211 may be provided on the inner peripheral wall of the cavity 21. The plurality of grooves 211 may be arranged at intervals along the circumferential direction of the cavity 21. Each groove 211 may extend along the axial direction (left - right direction) of the cavity 21 and penetrate through the cavity 21. As Figure 12 As shown, a plurality of protrusions 311 may be integrally formed on the outer peripheral wall of the housing 31. The protrusions 311 may be in the form of ribs. The plurality of protrusions 311 are arranged at intervals along the circumferential direction of the housing 31. Each protrusion 311 extends along the axial direction of the housing 31.

[0093] During the process of inserting the housing 31 into the cavity 21, the plurality of protrusions 311 may be inserted into the plurality of grooves 211 one by one. By the blocking and limiting of the protrusions 311 and the grooves 211, the anti - rotation assembly of the housing 31 and the cavity 21 can be achieved. At this time, the form between the cavity 21 and the housing 31 may be non - interference. Thus, both the structural stability of the assembly is ensured and it is beneficial to simplify the assembly process.

[0094] In some embodiments, the housing 31 is tightly fixed in the cavity 21. For example, as Figure 11 As shown, the cavity 21 may generally be a hoop - shaped structure, that is, the cavity 21 may be provided with a slot, and the slot connects the inner cavity of the cavity 21 with the outside. When assembling the housing 31, the housing 31 can be directly inserted into the cavity 21, and then the two parts of the cavity 21 on both sides of the slot can be connected and fixed by bolts or the like, so that the cavity 21 can be tightly fixed on the outer peripheral side of the housing 31, improving the convenience of assembly and disassembly.

[0095] In some embodiments, the shock absorption assembly may include a bushing 7. The end cap 5 may be fixed and sealed at the port of the cavity 21. The end cap 5 is provided with an end cap hole. The bushing 7 is anti - rotationally assembled on the outer peripheral side of the shaft body 33, and at least part of the bushing 7 is rotationally fitted in the end cap hole.

[0096] For example, as Figure 7 As shown, the end cap 5 may generally be a circular disk shape. The end cap 5 may be fixed to the left or right side of the cavity 21 by screws or the like. The inner through - hole of the end cap 5 is the end cap hole, and the end cap hole is a circular hole. The bushing 7 is annular, the outer peripheral contour of the bushing 7 is circular, and the inner hole of the bushing 7 may be a square hole.

[0097] During assembly, a part of the bushing 7 may be assembled in the end cap hole, and the bushing 7 can rotate freely in the end cap hole. The anti - rotation part 333 of the shaft body 33 can be fitted in the inner hole of the bushing 7. By the blocking cooperation between the inner hole wall and the anti - rotation part 333, the anti - rotation assembly of the shaft body 33 and the bushing 7 can be achieved. When the rocker arm 2 swings, the end cap 5 can rotate synchronously with the rocker arm 2, and the bushing 7 and the shaft body 33 can rotate freely in the end cap hole.

[0098] Optionally, the outer peripheral surface of the bushing 7 can be stepped, that is, the bushing 7 includes a large-diameter section with a larger outer diameter dimension and a small-diameter section with a smaller outer diameter dimension. The small-diameter section can be rotatably fitted in the end cap hole, and the large-diameter section can abut against the outer end surface of the end cap 5.

[0099] In some embodiments, the shock absorption assembly includes a compression ring 8 and a fastener 9. The compression ring 8 is sleeved on the outer peripheral side of the shaft body 33 and is located between the bushing 7 and the fastener 9. The fastener 9 is fixed to the end of the shaft body 33 and blocks and limits the compression ring 8 on the shaft body 33.

[0100] For example, as Figure 7 shown, the compression ring 8 can be a flat-round tubular shape, the fastener 9 can be a nut, the compression ring 8 can be sleeved on the end of the shaft body 33, and the fastener 9 can be threadedly assembled on the end of the shaft body 33. By the action of the fastener 9, the compression ring 8 can abut between the bushing 7 and the fastener 9, thereby realizing the limiting and fixing of the end of the shaft body 33 and avoiding the situation that the bushing 7 comes off from the end of the shaft body 33.

[0101] It should be noted that, as Figure 7 shown, end caps 5, bushings 7, compression rings 8 and fasteners 9 are correspondingly assembled at both the left and right ends of the shaft body 33, thereby realizing the fixing of both the left and right ends of the shaft body 33.

[0102] In some embodiments, as Figures 13 to 15 shown, the rocker arm 2 includes two arm bodies 22 arranged oppositely in the left-right direction. The wheel 4 is assembled between the two arm bodies 22, and the left end of the wheel axle of the wheel 4 can be fixedly connected to the front end of the left arm body 22, and the right end of the wheel axle of the wheel 4 can be fixedly connected to the front end of the right arm body 22. The rear ends of the two arm bodies 22 are integrally formed with the cavity 21.

[0103] In some embodiments, the cavity 21 and the shock absorption component 3 are located on the front side or the rear side of the wheel 4. For example, as Figure 10 shown, the fork arms 11 of the front fork 1 can be generally inclined in the direction from the front upper to the rear lower, and the fork arms 11 can be located at the rear side of the wheel 4. At this time, the rocker arm 2 and the wheel 4 are located at the front side of the fork arms 11, and the cavity 21 and the shock absorption component 3 are located at the rear side of the wheel 4.

[0104] In some other embodiments, as Figure 16 shown, the fork arms 11 of the front fork 1 can be generally inclined in the direction from the rear upper to the front lower, and the fork arms 11 can be located at the front side of the wheel 4. At this time, the rocker arm 2 and the wheel 4 are located at the rear side of the fork arms 11, and the cavity 21 and the shock absorption component 3 are located at the front side of the wheel 4. Thereby, the flexibility of the arrangement is improved, making it possible to configure according to actual needs.

[0105] The scooter of the embodiments of the present invention will be described below.

[0106] The scooter of the embodiment of the present invention includes a shock absorption assembly, which can be the shock absorption assembly described in any of the above embodiments. The scooter can be a vehicle such as a scooter or a bicycle, and of course, it can also be other scooters that need to install a shock absorption assembly.

[0107] In some embodiments, as Figure 16 shown, the scooter includes a fender 10 and a wheel 4. The wheel 4 is specifically the front wheel of the scooter. The axle of the wheel 4 is connected to the rocker arm 2, and the fender 10 covers the outer peripheral side of the wheel 4 and is connected to the rocker arm 2. For example, two extension parts can be integrally formed on the fender 10. The two extension parts can be generally arranged to extend in the direction from the front lower to the rear upper, and the bottom ends of the two extension parts can be connected and fixed to the corresponding rocker arm 2 by screws or the like. Thus, when the rocker arm 2 and the wheel 4 swing up and down, the fender 10 can also move synchronously with the wheel 4, ensuring the mud blocking effect.

[0108] Although the above embodiments have been shown and described, it can be understood that the above embodiments are exemplary and should not be construed as limitations of the present invention. Any changes, modifications, substitutions, and variations made by those of ordinary skill in the art to the above embodiments are within the protection scope of the present invention.
