Technical Field

The present invention relates to a wiper structure, and more particularly, to a waterproof wiper structure.

Background

The automobile windshield wiper is arranged on the outer side face of the automobile glass and is connected with the windshield wiper driving arm, the windshield wiper driving arm applies acting force to the windshield wiper and drives the windshield wiper to swing repeatedly on the glass face so as to scrape off foreign objects such as rainwater or dirt on the glass.

In addition, the general windshield wiper structure mainly comprises a buckling seat, a metal elastic sheet, a guide cover and a windshield wiper adhesive tape. The buckling seat is combined with the metal elastic sheet and the windshield wiper rubber strip, and the air guide sleeve is installed at the top of the buckling seat and connected with the windshield wiper driving arm, so that the windshield wiper rubber strip is driven to move through the windshield wiper driving arm to clean the glass surface of the automobile.

However, since the combination between the air guide sleeve and the metal spring in the windshield wiper structure is not sealed, rainwater easily permeates into the air guide sleeve and infiltrates into the metal spring, so that the metal spring is easily rusted and the service life is shortened. Particularly, when the metal spring plate is used in an ice-cold environment, the original elastic force of the metal spring plate can be lost due to ice formation, so that the metal spring plate needs to be further improved.

In the present embodiment, the elastic sheet 30 penetrates the through groove 210 and extends to two sides of the carrier 20. Preferably, the spring 30 is a metal spring.

The waterproof socket 40 includes a casing 41, an internal space 42 provided in the casing 41, and an external space 43 formed outside the casing 41. The bearing seat 20 is inserted into the inscription space 43. Specifically, the internal space 42 and the external space 43 are respectively U-shaped, and one side of the external space 43 is an opening 44.

In more detail, the case 41 includes a top wall 411 attached to the fastening base 10, an inner bottom wall 412 opposite to the top wall 411 and attached to the carrier 21, and two side walls 413 connecting the top wall 411 and the inner bottom wall 412. It should be noted that, in the present embodiment, the thickness of the top wall 411 is greater than the thickness of the two side walls 413, so that the waterproof socket 40 can maintain the required structural strength and flexibility without buckling and maintain a good appearance. In the present embodiment, the thickness of the top wall 411 is about 0.5mm to 1mm; the thickness of the side wall 413 is 0.3mm to 0.6mm.

The waterproof socket 40 is made of a polyolefin thermoplastic elastomer (TPV, thermoplastic Vulcanizate). The polyolefin thermoplastic elastomer is a stable elastomer which is formed by mixing two substances of ethylene propylene diene monomer (EPDM, ethylene Propylene Diene Monomer) and Polypropylene (PP, polypropylene) which are dynamically vulcanized, and has the characteristics of no toxicity, environmental protection, good ageing resistance, small change of hardness along with temperature and the like. In addition, the TPV does not contain cancerogenic substances such as nitrite, does not contain heavy metals and can be recycled, so that the TPV achieves the sanitation grade, passes SGS authentication and accords with the European Union ROHS specification. In addition, the use temperature of the TPV can reach-30 ℃ to 120 ℃, and the encourage hardness change is not higher than 5A within the temperature range of-20 ℃ to 40 ℃, which is superior to the prior PVC and EPDM materials.
