[0002] Wipers are crucial components on cars, clearing rain, snow, dust, and dirt from the windshield to ensure a clear view for the driver and enhance driving safety. Wiper types and usage scenarios can be categorized into standard wipers and smart wipers. Standard wipers primarily clear rainwater, while smart wipers automatically adjust wiper speed based on rainfall and can even identify rainy or snowy conditions, providing a more intelligent driving experience.

[0003] The wiper bearing is an important component of the automobile wiper system. It mainly supports and fixes the wiper arm, allowing the wiper blade to move smoothly on the windshield and remove rainwater and debris. As shown in the prior art of publication number CN207470606U, although the capping plate is installed by a fixing bolt in the prior art, since the baffle provided at the bottom of the outer ring can support the roller, the roller is first placed in the gap between the inner ring and the outer ring during installation, and then covered by the capping plate. In this way, the roller will not fall out, allowing the bearing to be used normally. In addition, the fixing bolt used by the capping plate is provided with a movable column inside. When the movable column is pressed down, the first and second rotating shafts drive the crossbar to extend to both sides, so that the crossbar can be just stuck into the limit hole. However, the installation steps of the capping plate in the prior art are relatively cumbersome, requiring the insertion of multiple fixing bolts and the pressing of the movable column inside the fixing bolt for subsequent fixation, which affects the operating efficiency.
