Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of automobile parts, especially relates to a high-efficiency detachable universal wiper. BACKGROUND
[0002] As a vital component on the car, the wiper bears the heavy responsibility of removing rain, snow and dust on the windshield, ensuring the driver's clear vision and thus ensuring driving safety. Its structure usually covers core components such as motor, transmission mechanism, rocker and wiper holder, and through the motor driving the transmission mechanism, the rocker and wiper holder are driven to move back and forth in order to realize the water scraping function.
[0003] However, after analyzing the technical status of the existing wiper, we can easily find that it has many limitations:
[0004] Firstly, the existing wiper design usually only allows the wiper holder to be detached on the rocker, and the rocker itself, as a long and easily stressed component, lacks an effective disassembly and replacement mechanism. Once the rocker is damaged, the wiper assembly often needs to be replaced as a whole, increasing the maintenance cost and time cost, and causing unnecessary resource waste; secondly, the wiper holder design of the existing wiper is often single, and it is difficult to flexibly adapt to the shape and curvature of the windshield of different types of cars. This design limitation leads to poor water scraping effect of the wiper on some car models, and even may damage the windshield due to mismatch, affecting the driver's vision and driving safety; in addition, in actual use, impurities such as sand and leaves will inevitably adhere to the car windshield. The presence of these impurities can easily cause the wiper holder to be blocked during normal sliding, affecting the water scraping effect, and even may damage the wiper holder or the windshield.
[0005] Therefore, it is necessary to invent a high-efficiency detachable universal wiper. CONTENT OF THE UTILITY MODEL
