[ detailed description ] embodiments
Referring to fig. 1-3, the bicycle cushion post 1 of the present invention has an outer tube 10 and an upper tube 20 positioned above the outer tube 10. The outer wall of the outer tube 10 is fixed to the frame of the bicycle at a location 11. A top end 21 of the upper tube 20 is provided with a locking device 22 for connecting the cushion; has a bottom end 23 extending from the top end of the outer tube 10 into the interior of the outer tube 10. A height adjusting device 3 for adjusting the height of the cushion and a shock absorbing and buffering device 4 for absorbing shock and buffering when the cushion is seated are disposed inside the cushion column 1.
The height adjusting device 3 is shown in fig. 1 and 3. Is a pneumatic rod or hydraulic rod, and is mostly disposed inside the outer tube 10. The present embodiment takes the pneumatic rod as an example, and includes a cylinder 30 and a tubular piston rod 31, which can be adjusted and displaced axially relative to each other, and a control unit 32. Wherein a top end 300 (also called a support end) of the cylinder 30 extends into the upper tube 20 for indirectly supporting the top end 21 of the upper tube 20. A top end 310 of the piston rod 31 extends into the cylinder 30, and a bottom end 311 is fixed to a fixing cap 12 fixed to the inside of the outer tube 10, so that the piston rod 31 is fixed. A striker 312 is disposed through the interior of the piston rod 31, the striker 312 can be pushed by the control unit 32 to open a valve inside the cylinder 30, so that the cylinder 30 and the piston rod 31 can perform relative axial displacement, and the upper tube 20 can adjust the height of the cushion along with the displacement of the cylinder 30. The control unit 32 is controllable via a control paddle fixed to the handlebar of the bicycle.
Fig. 1-2 show the shock absorbing and cushioning device 4. Is disposed inside the upper tube 20 and above the height adjusting device 3, and the cylinder 30 of the height adjusting device 3 has the function of indirectly supporting the upper tube 20 and the cushion through the installation of the shock absorbing and buffering device 4. Includes a sealed chamber 40, a buffer assembly 41 and a gas 42. The closed chamber 40 is located inside the upper tube 20 and is partitioned by a partition 400 (which may be a piston) disposed at the bottom end, an upper cover 401 disposed at the top end, and an inner wall of the upper tube 20. The outer wall of the spacer 400 is provided with an oil-blocking ring 402 and a wear-resistant ring 403 to contact the inner wall of the upper tube 20, so as to stop the oil flowing into the closed chamber 40 and prevent the spacer 400 from wearing against the inner wall of the upper tube 20. The bottom end of the spacer 400 contacts and supports the top end (support end) 300 of the cylinder 30 of the height adjusting device 3. The outer wall of the upper cover 401 is locked with a tooth surface 401a and a tooth surface 401b of the inner wall of the upper tube 20, as shown in fig. 2-3, the outer wall of the upper cover 401 has an air blocking ring 401c contacting with the inner wall of the upper tube 20 to block the air leakage. The upper lid 401 has a gas nozzle 401d, and the gas nozzle 401d is communicated from the outside of the sealed chamber 40 to the inside of the sealed chamber 40 for filling the gas 42 into the sealed chamber 40. The buffer member 41 is made of a material with elastic function (such as an elastic rubber or a compression spring). The buffer assembly 41 is disposed in the closed chamber 40, and the buffer assembly 41 has an axial through hole 410 in the middle, a bottom end contacting the spacer 400, and a top end contacting the upper cover 401, so that the buffer assembly 41 has an elastic supporting force for the top end 21 of the upper tube 20. The gas 42, which may be nitrogen, is filled into the sealed chamber 40 through the gas nozzle 401d, so that the sealed chamber 40 has a gas pressure.
In addition, a gap 24 between the inner wall of the upper tube 20 and the outer wall of the cylinder 30 is shown in fig. 3. The gap 24 is partitioned at its upper end by an oil control ring 402 of the spacer 400 and at its lower end by a lower oil control ring 25, and the lower oil control ring 25 is fixed to the inner wall of the bottom end 23 of the upper tube 20 to seal the gap 24. The gap 24 is filled with an oil 26, and the top end of the oil 26 has the effect of supporting the bottom end of the partition 400.
The above components are combined, as shown in fig. 1 and 3. When the height of the cushion is adjusted, the height adjusting device 3 is used to adjust the height of the cushion. When the control unit 32 is controlled to push the striker 312 upward to open the valve in the cylinder 30, the cylinder 30 can move axially, so that the upper tube 20 can adjust the height of the cushion along with the displacement of the cylinder 30. After the height of the cushion is adjusted, the height of the cushion can be fixed by releasing the control unit 32. After height adjustment, as shown in fig. 4, or lower in height as shown in fig. 5.
When a rider sits on the seat cushion (no matter the seat cushion is just sitting or riding on a bumpy road), the shock absorbing and buffering effect is achieved by mainly applying the shock absorbing and buffering device 4, as shown in fig. 6-7. When a rider sits on the seat cushion or rides on a bumpy road surface, the upper tube 20 moves axially downward due to the downward pressure, and at this time, the top end of the cushion element 41 is compressed and deformed along with the downward movement of the upper tube 20, so that the seat cushion has a shock absorbing and cushioning effect, as shown in fig. 7. Because the space in the closed chamber 40 decreases as the upper pipe 20 moves downward, the closed chamber 40 is originally filled with air 42, and the air 42 has air pressure, and the amount of the air pressure has the effects of adjusting the shock absorption and buffering stroke distance and buffering the hardness. Therefore, the rider can adjust the cushioning stroke distance and the cushioning softness of the seat cushion by filling the air nozzle 401d with air 42 to adjust the air pressure in the sealed chamber 40. Moreover, the cushioning force and the hardness of the cushion can be adjusted at any time according to the weight and the preference of the rider.
