[0002] Generally, a folding bicycle comprises a handlebar assembly, a front wheel assembly, a front fork, a seat tube, a seat handle, a rear fork, and a rear wheel assembly, wherein a shock-absorbing assembly is connected between the seat tube and the rear fork.

[0003] like Figure 13 The figure shows the structure and installation method of a suspension assembly on a folding bicycle in the prior art. The suspension assembly includes a locking seat 101, a first screw 102, a shock absorber column 103, and a second screw 104. The front end of the locking seat is provided with a locking slot and a first connecting hole, which extends through the front and rear ends of the locking seat. The first screw extends into the first connecting hole and connects to the shock absorber column, with the cap of the first screw located above the locking slot. The top crossbar 105 of the rear fork is provided with a connecting hole. Because the top crossbar of the rear fork is a hollow tube, two holes (a front hole and a rear hole) are provided on the front and rear walls of the hollow tube, and the two holes are aligned and extend through the front and rear sides. The folding assembly is provided on the seat tube for mounting the front end of the suspension assembly. Specifically, during installation, the locking slot of the locking seat is aligned with the locking hook of the folding assembly, and the second screw is then inserted through the connecting hole in the top crossbar of the rear fork to connect the top crossbar of the rear fork to the shock absorber column.

[0004] Due to the inevitable machining and assembly errors in the connection holes on the rear fork's top crossbar, the shock absorber assembly, and the folding assembly on the seat tube, the following results are inevitable: 1. Even if the second screw is properly aligned with the connection hole on the rear fork's top crossbar, there may be a large gap between the locking seat and the folding assembly, or even an unsatisfactory hook fit; 2. Even if the hook fit is perfect, the second screw may not align with the hole in the shock absorber column after passing through the connection hole on the rear fork's top crossbar. Therefore, the requirements for component machining and assembly accuracy are very high. Otherwise, assembly will be time-consuming and labor-intensive, requiring the replacement of parts and multiple attempts at matching and installation.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

Therefore, they cannot be understood as a limitation on the present invention.

[0043] like Figures 1 to 5 As shown, it shows the specific structure of embodiment 1:

[0044] A shock absorber assembly includes a locking seat 10 for connecting to a seat tube, a clamp 20 for connecting to a rear fork, and an annular spring piece 30 connected between the locking seat 10 and the clamp 20; the locking seat 10, the annular spring piece 30, and the clamp 20 are arranged in sequence along the front and back.

[0045] The front end of the locking seat 10 is provided with a locking groove 11 and a first connecting hole 12 , and the first connecting hole 12 passes through the front and rear ends of the locking seat 10 .

[0046] The clamp 20 includes a fixing seat 21 and an arcuate hoop piece 22 connected to the rear end of the fixing seat 21. A clamping cavity is formed between the rear side of the fixing seat 21 and the arcuate hoop piece 22, which is used to clamp and fix the clamp to the top crossbar 6' of the rear fork. The fixing seat 21 is located behind the locking seat 10. The fixing seat 21 is provided with a second connecting hole 211 that runs through the front and back. The arcuate hoop piece 22 is provided with a third connecting hole 221 that runs through the front and back. The third connecting hole 221 is arranged corresponding to the second connecting hole 211. The upper end of the arcuate hoop piece 22 is hinged to the upper end of the fixing seat 21, so that the arcuate hoop piece 22 can be flipped up and down to open and close. The lower end of the arcuate hoop piece 22 is detachably connected to the lower end of the fixing seat 21 via a locking screw 23. Furthermore, a mounting slot 212 is recessed rearwardly at the front end of the fixing seat 21 , an upper limit slot 213 is recessed upwardly at the top of the mounting slot 212 , and a lower limit slot 214 is recessed downwardly at the bottom of the mounting slot 212 .

[0047] The annular spring piece 30 includes a front end mounting plate portion 31, a rear end mounting plate portion 32, a left side arc-shaped spring piece portion 33 and a right side arc-shaped spring piece portion 34. The left side arc-shaped spring piece portion 33 is connected between the left side of the front end mounting plate portion 31 and the left side of the rear end mounting plate portion 32, and the right side arc-shaped spring piece portion 34 is connected between the right side of the front end mounting plate portion 31 and the right side of the rear end mounting plate portion 32; the front end mounting plate portion 31 is connected to the locking seat 10, and the rear end mounting plate portion 32 is connected to the fixing seat 21. The front mounting plate portion 31 is provided with a fourth connecting hole 311 which passes through the front and back, and the rear mounting plate portion 32 is provided with a fifth connecting hole 321 which passes through the front and back; the annular spring piece 30 is located between the locking seat 10 and the fixing seat 21; the fourth connecting hole 311 is provided corresponding to the first connecting hole 12, and the fifth connecting hole 321 is provided corresponding to the second connecting hole 211; usually, the annular spring piece 30 is an integrated metal spring piece, the left curved spring piece portion 33 and the right curved spring piece portion 34 are outwardly expanded arcs (for example, semicircular), which are elliptical (or runway-shaped) when viewed from above, and the front and rear widths are smaller than the left and right widths. The upper and lower heights of the annular spring piece 30 are greater than the thickness of its sheet. The thickness direction refers to the direction from the inner ring of the annular spring piece 30 to the outer ring. For the left curved spring piece portion 33 and the right curved spring piece portion 34, the sheet thickness is equal to the difference between the outer diameter and the inner diameter. The rear mounting plate portion 32 is positioned within the mounting slot 212, and the upper and lower ends of the rear mounting plate portion 32 extend into the corresponding upper and lower stop slots 213 and 214, thereby improving the installation reliability of the annular spring piece 30. Preferably, the diameter of the fifth connecting hole 321 is larger than the diameter of the second connecting hole 211, and the diameter of the fourth connecting hole 311 is larger than the diameter of the first connecting hole 12. This allows the annular spring piece 30 to move left and right relative to the mounting slot 212, the upper and lower stop slots 213, and the lower stop slot 214, reducing assembly difficulty and reserving a small amount of space for movement during shock absorption, which is beneficial to the fatigue resistance of the annular spring piece 30.

[0048] A guide screw 40 and a nut 50 are also provided; the cap of the guide screw 40 is located outside the front end of the locking seat 10 and above the locking groove 11, the rod of the guide screw 40 passes backward through the first connecting hole 12 and the fourth connecting hole 311, and the nut 50 is threadedly connected to the rear end of the rod.

[0049] A connecting screw 60 is also provided; the connecting screw 60 passes through the fifth connecting hole 321 and the second connecting hole 211 in sequence from front to back, and protrudes from the rear side of the fixing seat 21, so as to be inserted into the front connecting hole on the top cross bar 6' of the rear fork, mainly playing a locking role; an adjusting screw 24 is provided on the arc-shaped hoop piece 22, and the adjusting screw 24 passes through the third connecting hole 221 from the rear side to the front, and protrudes from the front side of the arc-shaped hoop piece 22, the front end outer diameter of the adjusting screw 24 is slightly smaller than the aperture of the rear connecting hole on the top cross bar 6' of the rear fork, so as to be inserted into the rear connecting hole on the top cross bar 6' of the rear fork, mainly playing a locking role, and can be fine-tuned to accommodate the original rear connecting hole on the bicycle and the processing error of the shock absorber assembly, ensuring that the top cross bar 6' of the rear fork is effectively locked and limited and clamped.

[0050] like Figures 6 to 8 As shown, it shows the specific structure of Example 2:

[0051] The second embodiment has the same basic structure as the first embodiment, differing primarily in that the second embodiment further includes a protective member 70 to prevent overpressure on the annular spring plate 30. The protective member 70 is located between the locking seat 10 and the fixing seat 21. Typically, the protective member 70 maintains a gap between the front mounting plate 31 and / or the rear mounting plate 32. The protective member 70 may be a cylindrical PU plastic member (or other material) with a built-in nut 50. This maintains a gap between the rear end of the protective member 70 and the rear mounting plate 32. Alternatively, the nut and protective member 70 may be provided separately. During assembly, a guide screw passes through the protective member 70, and the nut clamps the protective member 70 securely.

[0052] like Figure 9 As shown, it shows the specific structure of Example 3:

[0053] The basic structure of Example 3 is the same as that of Example 1, with the primary difference being the inclusion of a telescopic spring 80. Specifically, the telescopic spring 80 (or an elastic material shock-absorbing column) can be positioned between the front mounting plate 31 and the rear mounting plate 32. It is typically located at the center of the annular spring 30, with the left and right curved spring portions 33 and 34 symmetrically positioned relative to the telescopic spring or elastic material shock-absorbing column. The telescopic spring / elastic material shock-absorbing column is used to provide auxiliary elastic force.

[0054] like Figures 10 and 11The figure shows the specific structure of the fourth embodiment. The fourth embodiment has the same basic structure as the first embodiment, differing primarily in that it also includes a protective member 70 to prevent overpressure on the annular spring 30. The protective member 70 is located between the locking seat 10 and the fixing seat 21. Typically, the protective member 70 maintains a gap between the front mounting plate 31 and / or the rear mounting plate 32. The protective member 70 can be made of PU plastic (or other materials) and is U-shaped, comprising a horizontally extending upper stopper 71 and a lower stopper 72. The rear ends of the upper and lower stops 71 and 72 maintain a gap between the rear mounting plate 32 and the rear mounting plate 32. The gaps can be the same or different. The different gaps provide two levels of protection. The top of the upper stopper 71 provides a large flat area that can be used as a logo area 711 (for displaying a logo, etc.) or a decorative area. Similarly, a nut is built into the protective member 70 to control the gap between the rear end of the protective member 70 and the rear mounting plate 32. It is also possible to consider providing the nut and the protective member 70 separately. During assembly, the guide screw passes through the protective member 70 and the nut clamps and fixes the protective member 70 .

[0055] like Figure 12 As shown, it shows a folding bicycle, including a handlebar assembly 1, a front wheel group 2, a front fork 3, a seat tube 4, a seat handle 5, a rear fork 6, and a rear wheel group 7. A shock absorber assembly 8 is connected between the seat tube 4 and the rear fork 6, and the shock absorber assembly is a shock absorber assembly as described in any of the above items.

[0056] The design focus of the present invention is that the annular spring piece 30 and the clamp 20 are provided to improve the assembly versatility of the shock absorber assembly on the folding bicycle. At the same time, the annular spring piece 30 has a simple structure and a good shock absorption effect.

[0057] Secondly, the clamp 20 is provided with connecting screws and self-aligning screws 24, which form two-end stopper-type positioning for the two original holes on the top crossbar 6' of the rear fork. Under the clamping and positioning action of the clamp 20, the positioning is further strengthened, and the stopper is prevented from rotating relative to the top crossbar 6' of the rear fork, making the installation of the shock absorber assembly and the rear fork more stable and reliable. In the actual design, the front end outer diameter of the self-aligning screw 24 is slightly smaller than the hole diameter of the rear side connecting hole on the top crossbar 6' of the rear fork, which can be fine-tuned to adjust the center of the third connecting hole 221 on the arc-shaped clamp plate 22 to better align with the hole position on the top crossbar 6' of the rear fork.

[0058] Furthermore, the annular elastic sheet 30 may be provided with an anti-overpressure protection member 70 , and / or a telescopic spring / elastic material shock-absorbing column may be provided to provide auxiliary elastic force.

[0059] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
