Description

Technical Field

[0001] This invention relates to a wiper structure, and more particularly to a waterproof wiper structure. Background Technology

[0002] The windshield wiper assembly is located on the outer side of the car glass. It is connected to the wiper drive arm, which applies force to the wiper and causes it to swing repeatedly on the glass surface to remove rainwater or dirt and other foreign objects from the glass.

[0003] Furthermore, a typical windshield wiper structure mainly includes a mounting bracket, a metal spring, a deflector, and a wiper blade. The mounting bracket connects the metal spring and the wiper blade, and the deflector is then installed on top of the mounting bracket and connected to the wiper drive arm. The wiper drive arm then moves the wiper blade to clean the car's windshield.

[0004] However, because the connection between the windshield deflector and the metal spring in the aforementioned wiper structure is not sealed, rainwater can easily seep into the deflector and wet the metal spring, causing it to corrode and shorten its service life. Especially in cold environments, the metal spring may lose its original elasticity due to freezing, thus requiring further improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a sealed wiper structure that maintains the sealing of the internal components of the wiper, thereby maintaining the elastic compressive force of the metal spring and extending the service life of the wiper.

[0006] To achieve the above objectives, the present invention provides a sealed wiper structure comprising a fastener, a support seat, a spring, a waterproof sleeve, and an adhesive strip assembly. The support seat is attached to the bottom side of the fastener and includes a support plate and a support frame connecting the support plate. The support plate has a through groove, and the support frame has a receiving groove. The spring passes through the through groove and extends to both sides of the support seat. The waterproof sleeve includes a housing, an inner space disposed within the housing, and an outer space formed outside the housing. The support seat is disposed within the inner space. The adhesive strip assembly includes a through strip and a scraper strip connecting the through strip. The through strip is disposed within the outer space, and the scraper strip is exposed outside the waterproof sleeve.

[0007] It further includes a fixing seat, which is attached to the fastening seat, and the fixing seat covers the fastening seat and supports one end of a wiper drive arm.

[0008] It further includes a card holder with a pair of through holes, which are respectively provided on both sides of the support plate.

[0009] The support frame is composed of multiple claw hooks arranged opposite each other.

[0010] The housing includes a top wall that is attached to the fastener, an inner bottom wall that is attached to the support plate relative to the top wall, and two side walls that connect the top wall and the inner bottom wall. The thickness of the top wall is greater than the thickness of the two side walls.

[0011] It further includes a locking device that is sequentially inserted through the fastener, the top wall, the spring, the support plate, and the inner bottom wall.

[0012] The inner space and the outer space are both U-shaped, and one side of the outer space is an opening.

[0013] The adhesive strip assembly further includes a connecting section between the threading strip and the scraping strip, the connecting section being erected in the opening.

[0014] It further includes a pair of end plugs, which are arranged at both ends of the housing and seal the inner space.

[0015] Each end plug assembly includes an inner end plug and an outer end plug. The inner end plug is adhered to the housing, and the outer end plug is fitted over the inner end plug.

[0016] The present invention provides a sealed wiper structure in which the thickness of the top wall of the waterproof sleeve is greater than the thickness of the side wall, thereby enabling the waterproof sleeve to maintain the required structural strength and flexibility, and to maintain a good appearance without wrinkling.

[0017] The present invention provides a sealed wiper structure, wherein the two ends of the waterproof sleeve are connected to end plugs to seal the waterproof sleeve, so that the spring inserted inside can be isolated from external moisture.

[0018] Compared to existing technologies, the sealed wiper structure of the present invention is provided with a waterproof sleeve, and the spring passes through the support seat and is placed in the inner space of the waterproof sleeve. In addition, the end plug assembly is set at both ends of the waterproof sleeve and seals the inner space, thereby forming a sealed space, so that the spring placed in the inner space can isolate external moisture, thereby achieving the purpose of waterproofing and maintaining the necessary elasticity.
