[0002] The motorcycle shock absorber is an important component of the motorcycle. Its main function is to absorb and reduce the impact and vibration of the motorcycle during driving, thereby improving driving stability and comfort.

[0003] Many motorcycle front shock absorbers offer adjustable features to suit different road conditions and rider needs. Adjustments include adjusting preload, damping, or rebound speed. For example, preload can be adjusted to accommodate riders of different weights, while damping can be adjusted to control compression and rebound resistance.

[0004] The above-mentioned damping adjustment is only performed before riding, and cannot be adjusted at any time according to road conditions after riding, thereby causing the existing shock absorber to have a poor bottoming-out function. Summary of the Invention

[0026] The present invention will be further described below in conjunction with the accompanying drawings:

[0027] like Figure 1 — Figure 5As shown, this embodiment provides an intelligent anti-bottoming motorcycle shock absorber, including a spring system 1, a damping system 2 and an inertial variable diameter system 3. The spring system 1 includes an upper spring mounting seat 11, a main spring 12 and a lower spring mounting seat 13 installed in sequence. The main spring 12 is used to absorb impact and store energy. The damping system 2 has a frame end component 21 and a wheel end component 22. The frame end component 21 of the damping system 2 is installed on the upper spring mounting seat 11, and the wheel end component 22 of the damping system 2 is installed on the lower spring mounting seat 13. The wheel end component 22 slides with the frame end component 21 through a sliding pair. A damping channel 211 is provided in the frame end component 21. When the wheel end component 22 slides along the frame end component 21, it pushes the damping oil in the damping channel 211. The inertia variable diameter system 3 includes an inertia rod device 31, an air pressure generating device 32 and a variable diameter device 33. The variable diameter device 33 is installed on the damping channel 211. The inertia rod device 31 is slidably installed on the wheel end component 22. The air pressure generating device 32 is installed on the wheel end component 22. The inertia rod device 31 is transmission-connected to the air pressure generating device 32. The air pressure generating device 32 is connected to the inertia variable diameter system 3. When subjected to a large impact, the inertia rod device 31 drives the air pressure generating device 32 to increase the pressure, so that the variable diameter device 33 is activated and thereby reduces the diameter of the damping channel 211. The biggest difference between this shock absorber and a conventional shock absorber is that this shock absorber can automatically increase the damping when subjected to a large impact to avoid bottoming out.

[0028] Specifically, the frame end component 21 includes a main shock absorber cylinder 212 and a nitrogen tank device 213. The nitrogen tank device 213 is installed on the main shock absorber cylinder 212. The nitrogen tank device 213 includes an oil chamber 2131 and a nitrogen chamber 2132. The main shock absorber cylinder 212 and the oil chamber 2131 are connected through a damping channel 211 to generate damping. The wheel end component 22 slides along the main shock absorber cylinder 212 in a sealed manner. A main oil seal 2121 is provided between the wheel end component 22 and the main shock absorber cylinder 212 to prevent oil leakage.

[0029] Specifically, the wheel end component 22 includes a damping rod 221 and a damping piston 222. The damping piston 222 is installed on the damping rod 221. The damping piston 222 slides sealed along the main shock absorber cylinder 212 of the frame end component 21 and pushes the piston oil through the damping channel 211. The damping rod 221 is rotatably mounted with the tire of the motorcycle. When the tire passes through a bumpy section, the damping rod 221 pushes the damping piston 222 to slide along the main shock absorber cylinder 212, allowing the piston oil to pass through the damping channel 211 and generate damping.

[0030] Specifically, the inertia rod device 31 includes an inertia sliding rod 311 and a pre-compression spring 312. The pushing force of the pre-compression spring 312 is equal to the gravity of the inertia sliding rod 311. The pre-compression spring 312 is used to overcome the gravity of the inertia sliding rod 311. Under the pushing of the pre-compression spring 312, when the damping rod 221 moves under the bumpy road surface, the inertia sliding rod 311 slides along the damping rod 221, thereby causing the sliding groove 3111 to fluctuate. The inertia sliding rod 311 is provided with a sliding groove 3111 that cooperates with the air pressure generating device 32. The sliding groove 3111 is used to generate air pressure. After the sliding groove 3111 follows the ups and downs of the inertia sliding rod 311, the sliding groove 3111 pushes the air pressure generating device 32 to pressurize. After the air pressure generating device 32 is pressurized, the diameter reducing device 33 changes the diameter of the damping channel 211, thereby realizing automatic increase in the damping of the shock absorber on bumpy roads.

[0031] Specifically, the air pressure generating device 32 includes an air pressure generating airbag 321 and an air pressure generating plate 322. The air pressure generating plate 322 is installed on the air pressure generating airbag 321. The air pressure generating plate 322 is provided with an air pressure generating protrusion 3221 adapted to the sliding groove 3111. After the sliding groove 3111 follows the inertial sliding rod 311 and rises and falls, the sliding groove 3111 pushes the air pressure generating protrusion 3221 to squeeze the air pressure generating plate 322, so that the air pressure in the air pressure generating airbag 321 increases. Because the air pressure generating airbag 321 is connected to the reducing device 33, the air pressure generating airbag 321 pushes the reducing device 33 to move, thereby changing the diameter of the damping channel 211. The higher the degree of bumpiness, the higher the degree to which the air pressure generating airbag 321 pushes the reducing device 33 to move, making the damping channel 211 smaller and the damping of the shock absorber higher.

[0032] Specifically, the air pressure generating protrusion 3221 points to the middle of the sliding groove 3111, which increases the air pressure in the air pressure generating airbag 321 when a large bump occurs, increases the damping of the damping channel 211, and prevents bottoming out.

[0033] Specifically, the reducing device 33 includes a reducing airbag 331, a reducing plug 333 and a reducing piston 332. The reducing piston 332 slides along the reducing plug 333. The reducing piston 332 points to the damping channel 211. The reducing plug 333 is installed on the damping channel 211. The reducing airbag 331 is installed on the reducing plug 333. The reducing airbag 331 is used to push the reducing piston 332 to move. The reducing airbag 331 is connected to the air pressure generating airbag 321, so that the air pressure change of the air pressure generating airbag 321 is fed back to the reducing airbag 331 in the first time, thereby realizing rapid damping adjustment.

[0034] Specifically, the air pressure generating device 32 is connected to the inertial variable diameter system 3 via a spiral air pipe 34 , and the spiral air pipe 34 adapts to the fluctuation of the damping rod 221 , so that the air supply is stable.
