Dustproof type shock absorber with oil leakage detection function

Abstract

The invention relates to a dustproof type shock absorber with an oil leakage detection function. The dustproof type shock absorber comprises a connecting block, a piston rod, a first spring, an oil seal, a first piston, a stop valve, an oil storage chamber, an oil cylinder and at least two oil holes, and further comprises a detection mechanism and a dust removal mechanism, wherein the detection mechanism comprises a check assembly, an oil tank and two alarm assemblies, and the dust removal mechanism comprises two fixing rods, a second baffle, a first bearing seat, a cleaning brush, a first gear and a driving assembly. In the dustproof type shock absorber with the oil leakage detection function, oil leakage can be timely detected through the detection mechanism when slight oil leakage occurs in the shock absorber, and meanwhile, an alarm signal is sent to remind people, so that the probability of accidents caused by oil leakage of the shock absorber is reduced; and dust on the piston rod can be cleared away thoroughly through the dust removal mechanism, so that the probability of the dust being brought into the shock absorber by the piston rod is reduced, then the interior of the shock absorber can be kept clean, and the probability of faults of the shock absorber is reduced.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a dust-proof shock absorber with an oil leakage detection function. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles. , Extended range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, other new energy vehicles, etc. [0003] As an important part of new energy vehicles, the shock absorber is prone to oil leakage due to the aging and loosening of the oil seal during the long-term driving of the new energy vehicle, thus making the shock absorber lose its shock absorbing effect , a serious threat to the driving safety of new energy vehicles, not only...

Problems solved by technology

[0003] As an important part of new energy vehicles, the shock absorber is prone to oil leakage due to the aging and loosening of the oil seal during the long-term driving of the new energy vehicle, thus making the shock absorber lose its shock absorbing effect , a serious threat to the driving safety of new energy vehicles, not only that, but the piston rod of the general shock absorber tends to accumulate dust, so that the piston rod is easy to bring dust into the interior of the oil cylinder during the expansion and contraction process, resulting in dust reduction. The valve inside the shock is blocked, which reduces the performance of the shock absorber, thereby reducing the comfort of passengers riding in new energy vehicles
