Description
Technical Field
[0001] The utility model relates to a seat cushion tube shock-absorbing stroke pre-adjusting structure, which is mainly used in the technical field of bicycles. Background Art
[0002] Bicycles are widely used as a means of transportation, leisure, or exercise, and are being adopted by users with diverse needs. The development of various bicycle components is also becoming increasingly diverse and functional. Take the seat assembly, for example. It is no longer simply for the rider to sit on. To accommodate the rider's height, existing seat assemblies utilize a seat tube mounted on a vertical tube of the frame, allowing the seat height to be adjusted. Furthermore, to accommodate varying road conditions, the seat assembly has been further developed to provide a shock-absorbing and cushioning effect. This is achieved by installing a seat bar at the top of the seat tube for the seat to lock onto, and a shock-absorbing structure with an elastic cushioning effect inside the seat tube, providing the rider with a better riding experience.
[0003] However, the suspension structure within the seat tube has a fixed travel, and therefore the resulting cushioning force is also fixed. When a bicycle is used on relatively flat urban roads, a stiffer suspension structure with a shorter travel is typically required. Conversely, when a bicycle is used on bumpy roads, such as in mountainous or suburban areas, a softer suspension structure with a longer travel is typically required to absorb greater shock. If the same suspension structure were used throughout the seat tube, the shock absorption would be unsmooth and unstable, affecting the ride comfort. Therefore, manufacturers typically need to prepare suspension structures with different travels during manufacturing, which inadvertently increases their material preparation costs.
[0004] In other words, the shock-absorbing structure of the existing bicycle seat assembly cannot be pre-adjusted to suit different bicycle models and needs further improvement. Utility Model Content

[0021] This invention creates a seat tube shock-absorbing travel pre-adjustment structure, such as Figure 1 As shown, it includes a shock-absorbing tube assembly 20, a seat bone 60, and an adjustment link assembly 40 disposed between the shock-absorbing tube assembly 20 and the seat bone 60. The seat bone 60 can be optionally locked with a seat pad (not shown). The adjustment link assembly 40 can be used to adjust the shock-absorbing stroke of the shock-absorbing tube assembly 20 to pre-adjust the rigidity of its buffering effect.
[0022] Its detailed composition is as follows Figure 2 、 Figure 3 and Figure 4 As shown, the shock absorber tube assembly 20 has a seat tube 21 that can be selectively assembled in a frame vertical tube (not shown in the figure), an elastic member 22 is abutted against the seat tube 21, and a bushing 23 is plugged into the top end of the seat tube 21. A brake slider 24 is slidably installed at the bottom end of a shock absorbing piston rod 35 on the seat tube 21 to abut against the top end of the elastic member 22, so that the elastic member 22 can be selectively compressed through the brake slider 24 to produce a buffering effect. A mounting seat 30 is locked at the top end of the seat tube 21. The axis of the mounting seat 30 has an axial hole 31 connected to the seat tube 21 for the shock absorbing piston rod 35 to slide through, and the shock absorbing The piston rod 35 can pass through the bushing 23 and abut against the top of the brake slider 24, so that the shock-absorbing piston rod 35 can selectively push the brake slider 24 to compress the elastic member 22, allowing the shock-absorbing piston rod 35 to generate an elastic shock-absorbing stroke relative to the seat tube 21. A top plug 36 can be provided at the top of the shock-absorbing piston rod 35 to form a flat abutment surface. Furthermore, the mounting seat 30 has a mounting lug 32 extending upward and obliquely on one side of its periphery. The mounting lug 32 has a first upper pivot hole 33 near the top end and a first lower pivot hole 34 near the bottom end for the pivotal mounting of the adjustment link assembly 40.
[0023] The seat frame 60 has a tie portion 61 for selectively locking the seat cushion. A seat frame lug 62 protrudes downward from the side of the seat frame 60 corresponding to the mounting lug 32. The seat frame lug 62 has a second upper pivot hole 63 near the top and a second lower pivot hole 64 near the bottom for pivoting the adjustment link assembly 40. Furthermore, an abutment surface 65 is formed on the side of the seat frame lug 62 corresponding to the mounting lug 32.
[0024] The adjusting link assembly 40 comprises an upper connecting seat 41 and a lower connecting seat 51, wherein the upper and lower connecting seats (41, 51) are respectively formed with side patches (42, 52) on both sides of the mounting lug 32 and the seat bone lug 62, and the side patches 42 on both sides of the upper connecting seat 41 have a first pivot hole 43 at one end corresponding to the mounting lug 32, for a first pivot rod 45 to penetrate the first pivot hole 43 of the upper connecting seat 41 and the first upper pivot hole 33 of the mounting lug 32, and the side patches 42 on both sides of the upper connecting seat 41 have a second pivot hole 44 at one end corresponding to the seat bone 60, for a second pivot rod 46 to penetrate the second pivot hole 44 of the upper connecting seat 41 and the seat bone 6 0, and the side patches 52 on both sides of the lower connecting seat 51 have a third pivot hole 53 at one end corresponding to the mounting lug 32, for a third pivot rod 55 to be pivoted through the third pivot hole 53 of the lower connecting seat 51 and the first lower pivot hole 34 of the mounting lug 32, and the side patches 52 on both sides of the lower connecting seat 51 have a fourth pivot hole 54 at one end corresponding to the seat bone 60, for a fourth pivot rod 56 to be pivoted through the fourth pivot hole 54 of the lower connecting seat 51 and the second lower pivot hole 64 of the seat bone 60, so that the upper and lower connecting seats (41, 51) of the adjustment link assembly 40 can be pivotally arranged between the mounting lug 32 of the mounting seat 30 and the seat bone lug 62 of the seat bone 60;
[0025] Furthermore, the upper connecting seat 41 has a locking hole 47 on one side of the surface corresponding to the lower connecting seat 51. The locking hole 47 can be selectively locked with a buffer pad 48. The buffer pad 48 can be selected from a thinner buffer pad 48A (such as Figure 4 As shown] or a thicker cushion block 48B [as Figure 6 As shown, the abutment surface 65 is configured to selectively abut against the seat frame lug 62, thereby generating a first preloaded shock absorbing stroke L1 or a second preloaded shock absorbing stroke L2 of varying lengths by changing the return position of the seat frame 60. The lower connecting seat 51 has a locking ear 57 on one side of the surface corresponding to the shock absorbing piston rod 35. The locking ear 57 can be locked to a wheel shaft 58 pivotally provided with a pressing roller 59, so that the pressing roller 59 can selectively press the top plug 36 of the shock absorbing piston rod 35. Figure 4 and Figure 5 As shown, the shock absorbing piston rod 35 is selectively actuated to compress the elastic member 22 in the seat tube 21 to produce a buffering effect, thereby forming a seat tube shock absorbing stroke pre-adjustment structure that can pre-adjust the buffering effect according to the installed vehicle model.
[0026] Through the above structural description, the seat tube shock absorber travel pre-adjustment structure of this invention is actually actuated as follows Figure 2 、 Figure 4 and Figure 5As shown, when the seat cushion is not subjected to load, the elastic member 22 in the seat tube 21 of the shock absorber tube assembly 20 is subjected to the restoring preload, and sequentially pushes the brake slider 24 and the shock absorbing piston rod 35 upward, so that the shock absorbing piston rod 35 pushes the pressing roller 59 of the adjustment link assembly 40, so that the upper connecting seat 41 and the lower connecting seat 51 of the adjustment link assembly 40 are upwardly deflected and reset, and the buffer pad 48A of the upper connecting seat 41 can be abutted against the abutting surface 65 of the seat bone lug 62 in the seat bone 60 to limit the height of the elastic member 22 pushing the shock absorbing piston rod 35 to reset. In contrast, when the buffer pad 48 is selected from the thinner buffer pad 48A (as shown in FIG. Figure 4 As shown in FIG, the elastic member 22 can be reset to a longer length and the shock absorbing piston rod 35 is pushed upward to a higher position (A), thereby obtaining a longer first preload shock absorbing stroke L1, and making the elastic member 22 have a lower rigidity buffering effect, so as to be suitable for mountaineering bicycles. On the contrary, when the buffer pad 48 is selected from the thicker buffer pad 48B (as shown in FIG, Figure 6 As shown in FIG. 1 , the elastic member 22 can be reset to a shorter length, pushing the shock-absorbing piston rod 35 upward to a lower position (B). This can achieve a shorter second preload shock-absorbing stroke L2, and thus the elastic member 22 has a higher rigidity for a cushioning effect, making it suitable for road-type bicycles.
[0027] like Figure 5 As shown, when the seat cushion carries the rider, the seat bone 60 will be pressed downward. At this time, the upper and lower connecting seats (41, 51) of the adjustment link assembly 40 can be actuated by the seat bone 60 to swing downward, so that the pressing roller 59 of the lower connecting seat 51 can push the shock-absorbing piston rod 35, and then use the shock-absorbing piston rod 35 to push the elastic member 22 in the seat tube 21 with the brake slider 24. In this embodiment, the buffer pad 48 of the adjustment link assembly 40 is selected to be thinner than the buffer pad 48A, and the elastic member 22 has a longer first pre-loaded shock-absorbing stroke L1. When the seat bone 60 with the seat cushion swings downward under force, the elastic member 22 in the seat tube 21 can produce a buffering effect, thereby improving the comfort of the rider.
[0028] From the above description, it can be seen that the seat cushion tube shock-absorbing stroke pre-adjustment structure of the present invention can utilize the adjustment link assembly 40 between the shock-absorbing piston rod 35 of the shock-absorbing tube assembly 20 and the seat bone 60 to generate a downward pressing and resetting swinging action. At the same time, the thickness of the buffer pad 48 on the upper connecting seat 41 of the adjustment link assembly 40 that can be abutted against the seat bone 60 can be adjusted to adjust the resetting height of the shock-absorbing piston rod 35 to adjust its relative shock-absorbing stroke. In this way, when assembling bicycles, the car manufacturer can select the buffer pad 48 of different thicknesses according to the different models of bicycles on the road conditions to change the shock-absorbing stroke of the shock-absorbing tube assembly 20, so that the shock-absorbing tube assembly 20 of the same specification can be suitable for different models, which can further effectively reduce the material preparation cost of the car manufacturer and greatly improve its practicality.
