Description

Technical Field

[0001] The present invention relates to the technical field of shock absorbers, and particularly to a self-detecting intelligent motorcycle shock absorber for damage. Background Art

[0002] Many motorcycle shock absorbers have adjustable functions to adapt to different road conditions and rider needs. The adjustment functions include adjusting preload, damping, or rebound speed, etc. For example, the preload is adjusted to adapt to riders of different weights, and the damping is adjusted to control the resistance during compression and rebound. Regular maintenance is also crucial to ensure the performance of the shock absorber, including regularly replacing the shock absorber oil and performing maintenance to avoid performance degradation caused by the deposition of metal debris.

[0003] Since the damping control of the shock absorber is achieved by controlling the diameter of the oil flow passage of the shock absorber oil, there is a possibility of oil leakage in the shock absorber after long-term use. At the beginning, the change in the driving experience is not obvious when the oil starts to leak, but as the oil leakage continues, the shock absorber oil gradually leaks and loses damping, and finally the damping of the shock absorber fails. Existing shock absorbers do not have the function of sensing oil leakage. Often, when the driver feels it, the impact on the handling performance of the motorcycle has reached a relatively serious level, resulting in serious safety hazards in driving. Summary of the Invention

[0004] To overcome the technical defects existing in the prior art, the present invention provides a self-detecting intelligent motorcycle shock absorber for damage, which has a self-detection function for damage.

[0005] The technical solution adopted by the present invention is:

[0006] The self-detecting intelligent motorcycle shock absorber includes a spring system, a damping system, and an oil leakage sensing system. The spring system includes an upper spring mounting seat, a main spring, and a lower spring mounting seat that are sequentially installed. The damping system has a frame end component and a wheel end component. The frame end component and the wheel end component are slidably arranged relative to each other. The frame end component of the damping system is installed on the upper spring mounting seat, and the wheel end component of the damping system is installed on the lower spring mounting seat. The oil leakage sensing system includes a conductive contact plate device and a sensing protrusion device. The conductive contact plate device is installed at the bottom of the frame end component, and the sensing protrusion device is installed on the wheel end component. The conductive contact plate device conducts electricity when it contacts the sensing protrusion device. The surface of the sensing protrusion device is provided with an oil-attached plane. When the oil-attached plane has oil stains, the circuit between the conductive contact plate device and the sensing protrusion device is blocked. The sensing protrusion device is provided with an electric key adapted to the conductive contact plate device.

[0007] Preferably, the frame end component includes a main shock absorber cylinder and a nitrogen tank device. The nitrogen tank device is installed on the main shock absorber cylinder.

[0008] Preferably, the wheel end component includes a damping rod and a damping piston. The damping piston is installed on the damping rod. The damping piston slides sealingly along the frame end component.

[0009] Preferably, the conductive contact plate device includes two elastic conductive plates. Each elastic conductive plate is installed at the bottom of the frame end component. Each elastic conductive plate moves relative to the sensing protrusion device. The movement path of each elastic conductive plate passes through the sensing protrusion device.

[0010] Preferably, the sensing protrusion device includes a protrusion nut and an oil guide sleeve. The protrusion nut is installed on the wheel end component through a thread pair. The oil guide sleeve is installed on the protrusion nut. An oil-impregnated cotton layer is provided between the oil guide sleeve and the damping rod of the wheel end component. A unified oil outlet hole is provided on the oil guide sleeve.

[0011] Preferably, the middle of the protrusion nut is thick and the two ends are thin. The protrusion nut is provided with an electric key adapted to the elastic conductive plate.

[0014] The beneficial effects of the present invention are:

After oil leakage, since the sensing protrusion device will be contaminated with oil stain, an insulation effect will occur after the conductive touch plate device contacts the sensing protrusion device, causing the conductive touch plate device to lose power, thereby sensing oil leakage.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] AsFigure 1 — Figure 5 As shown in Figure 5 , this embodiment provides a self-detecting damaged intelligent motorcycle shock absorber, which includes a spring system 1, a damping system 2, and an oil leakage sensing system 3. The spring system 1 includes an upper spring mount 11, a main spring 12, and a lower spring mount 13 installed in sequence. The main spring 12 is used to absorb shocks. The damping system 2 has a frame-end component 21 and a wheel-end component 22, and the frame-end component 21 and the wheel-end component 22 are slidably arranged relative to each other. The frame-end component 21 of the damping system 2 is installed on the upper spring mount 11, and the wheel-end component 22 of the damping system 2 is installed on the lower spring mount 13. The frame-end component 21 and the wheel-end component 22 generate damping during their relative movement. The oil leakage sensing system 3 includes a conductive contact plate device 31 and a sensing protrusion device 32. The conductive contact plate device 31 is installed at the bottom of the frame-end component 21, and the sensing protrusion device 32 is installed on the wheel-end component 22. When the conductive contact plate device 31 contacts the sensing protrusion device 32, it conducts electricity. The surface of the sensing protrusion device 32 is provided with an oil-attached plane. When there is oil stain on the oil-attached plane, the circuit between the conductive contact plate device 31 and the sensing protrusion device 32 is blocked. After oil leakage, since the sensing protrusion device 32 will be stained with oil stain, an insulation effect will occur after the conductive contact plate device 31 contacts the sensing protrusion device 32, causing the conductive contact plate device 31 to lose power, thereby sensing oil leakage.

[0027] Specifically, the frame-end component 21 includes a main shock absorber cylinder 211 and a nitrogen tank device 212. The nitrogen tank device 212 is installed on the main shock absorber cylinder 211. The nitrogen tank device 212 includes an oil chamber and a nitrogen chamber. The main shock absorber cylinder 211 is communicated with the oil chamber, thereby generating damping during the sliding process of the wheel-end component 22. The wheel-end component 22 slides sealingly along the main shock absorber cylinder 211. A main oil seal is provided between the wheel-end component 22 and the main shock absorber cylinder 211 to prevent shock absorber oil from leaking. The greater the nitrogen pressure filled in the nitrogen chamber, the more sufficient the support for the wheel-end component 22. Thus, the preload of the shock absorber is adjusted by controlling the nitrogen pressure filled in the nitrogen chamber.

[0028] Specifically, the wheel-end component 22 includes a damping rod 222 and a damping piston 223. The damping piston 223 is installed on the damping rod 222. The damping piston 223 slides sealingly along the main shock absorber cylinder 211 of the frame-end component 21, thereby pushing the shock absorber oil to flow from the main shock absorber cylinder 211 into the oil chamber. Damping is generated when the shock absorber oil flows, thereby making the shock absorber produce a damping effect.

[0029] Specifically, the conductive contact plate device 31 includes two elastic conductive plates 311. Each elastic conductive plate 311 is installed at the bottom of the vehicle frame end component 21. Each elastic conductive plate 311 moves relative to the sensing protrusion device 32, and the movement path of each elastic conductive plate 311 passes through the sensing protrusion device 32. It conducts electricity when the movement path of the elastic conductive plate 311 passes through the sensing protrusion device 32. However, when oil leaks, the sensing protrusion device 32 will be contaminated with oil. The oil-attached plane mentioned above refers to the surface of the sensing protrusion device 32. The oil-attached plane is contaminated with shock-absorbing oil, which leads to insulation. Since there is no current, the vehicle-mounted controller externally connected to the conductive contact plate device 31 senses that there is no electrical signal input, and thus senses oil leakage.

[0030] Specifically, the sensing protrusion device 32 includes a protruding nut 321 and an oil guide sleeve 322. The protruding nut 321 is installed on the wheel end component 22 through a thread pair, and the oil guide sleeve 322 is installed on the protruding nut 321 to guide the flow of shock-absorbing oil. In order to absorb all the leaked shock-absorbing oil and reliably block the electrical signal with the leaked damping oil, an oil-impregnated cotton layer 323 is provided between the oil guide sleeve 322 and the damping rod 222 of the wheel end component 22. The oil guide sleeve 322 is made of rubber, and a unified oil outlet hole 3221 is provided on the oil guide sleeve 322. After the elastic conductive plate 311 presses on the oil guide sleeve 322, the oil guide sleeve 322 squeezes the oil-impregnated cotton layer 323, so that the shock-absorbing oil in the oil-impregnated cotton layer 323 leaks out from the unified oil outlet hole 3221. Subsequently, the elastic conductive plate 311 is contaminated with shock-absorbing oil after passing through the unified oil outlet hole 3221, thereby blocking the electrical connection between the elastic conductive plate 311 and the protruding nut 321.

[0031] Specifically, the middle of the protruding nut 321 is thick and the two ends are thin to prevent the conductive contact plate device 31 from rigidly hitting the protruding nut 321. In order to prevent the protruding nut 321 from being always charged, an electric key 3211 adapted to the elastic conductive plate 311 is provided on the protruding nut 321. When the elastic conductive plate 311 presses on the electric key 3211, the electric key 3211 is energized, making the protruding nut 321 charged. That is to say, only when the elastic conductive plate 311 presses on the electric key 3211, the test is carried out, avoiding false alarms of oil leakage when the load is light because the protruding nut 321 and the elastic conductive plate 311 never contact and there is no current passing through. When there is no oil leakage, the conduction path is sequentially the elastic conductive plate 311, the electric key 3211, the protruding nut 321 and the other elastic conductive plate 311. Since the two elastic conductive plates 311 are externally connected to a commercially available vehicle-mounted controller, the electrical signal is transmitted to the vehicle-mounted controller. The vehicle-mounted controller is electrically connected to the electric key 3211. When the electric key 3211 is energized but the elastic conductive plate 311 and the protruding nut 321 are insulated due to shock-absorbing oil, the vehicle-mounted controller senses that the electric key 3211 is pressed and there is no electrical signal between the elastic conductive plate 311 and the protruding nut 321, thereby realizing intelligent detection.

[0032] Specifically, the oil leakage sensing system 3 further includes an oil scraping device, and the oil scraping device is an oil scraping sleeve 33 installed on the frame end member 21. The oil scraping sleeve 33 slides along the wheel end member 22, thereby accelerating the scraping of the leaked oil, preventing the leaked oil from being smeared on the damper rod 222, further preventing dust from gradually contaminating and covering the leaked shock absorber oil, and preventing the shock absorber oil from losing the ability to flow downward.

[0033] Specifically, the wheel end member 22 is provided with an avoidance groove 221 for avoiding the conductive contact plate device 31, so as to prevent the conductive contact plate device 31 from hitting the lower spring mounting seat 13.
