Description

Technical Field

[0001] The utility model relates to the technical field of anti-seepage of automobile swing arms, in particular to an automobile swing arm with an anti-seepage structure. Background Art

[0002] The automobile swing arm assembly is a key component of the chassis suspension system. Its main body is usually made of metal and has relatively stable quality. However, the quality of the matching ball head sub-assembly, front rubber bushing, rear rubber bushing and intermediate bushing varies greatly. The design of these accessories directly determines the performance of the swing arm assembly. For example, the structural design of the rubber bushing is related to its fatigue resistance and shock absorption effect, while the design of the ball head affects its rotation stability and durability.

[0003] The current automobile swing arm design does not include oil leakage monitoring and instant warning functions. When oil leaks and is not discovered in time, it may lead to insufficient lubrication of the ball head. Insufficient lubrication not only increases the wear of the device, but also may cause abnormal noise during operation, thereby shortening the service life of the swing arm assembly and potentially affecting driving safety. For example, the prior art represented by the comparative document, an automobile swing arm with an anti-leakage structure (publication number CN218906818U), is a patented technology that sets the connecting rod to tilt and squeezes one side of the baffle, so that the return spring is compressed and the gas inside the annular cylinder is compressed, driving the other side of the baffle to fit tightly with the side wall of the connecting rod, and the rubber ring is tightly fitted with the slot, so as to seal the gap generated when the ball pin and the connecting rod move to avoid oil leakage, thereby effectively solving the problems of the prior art, but its structure still needs to be improved, as follows:

[0004] In this solution, a connecting rod is used to tilt and squeeze the baffle, and the return spring is compressed to compress the gas inside the annular cylinder, driving the other side of the baffle to fit tightly with the side wall of the connecting rod, and fit tightly with the slot through a rubber ring. During daily use, the swing arm will be impacted by the bumps of the car, and the swing arm has high strength and will not be affected by the impact. However, the above-mentioned anti-leakage structure will be damaged by the impact, which can easily lead to failure of the above-mentioned structure. Therefore, a car swing arm with an anti-leakage structure is needed to improve the above-mentioned problem. Utility Model Content

[0017] The utility model can realize oil leakage monitoring and instant warning by arranging an anti-leakage component in the automobile swing arm with an anti-leakage structure. The humidity sensor generates data on the humidity of the inner cavity of the corrugated telescopic tube in real time. At the same time, the humidity sensor generates an electrical signal which is transmitted to the controller through a wire. When the set value is reached, the controller controls the buzzer to emit a buzzing sound to prompt personnel to perform maintenance, thereby solving the problem that when oil leakage occurs and is not discovered in time, the ball head may be insufficiently lubricated. Insufficient lubrication not only increases the wear of the device, but also may cause abnormal noise during operation, thereby shortening the service life of the swing arm assembly and potentially affecting driving safety.
