Abstract

The utility model discloses an automobile windshield washer sealing ring which comprises a sealing ring body, wherein a windshield washer water spray motor shaft is sleeved with the sealing ring body. Two inward bulge loops are arranged at the upper position and the lower position of the inner circumferential face of the sealing ring body, two outward bulge loops are arranged at the upper position and the lower position of the outer circumferential face of the sealing ring body, a stiffening ring is arranged on the outer circumferential face of the bottom of the sealing ring body, the section of each inward bulge loop inclines upwards, and the section of each outward bulge loop is in a triangular shape. The automobile windshield washer sealing ring has the advantages of being capable of greatly enhancing the sealing property of a water spray motor, enabling sealing to be stable and durable and greatly reducing fault rate.

Description

The automobile washing pot seal ring

Technical field

The utility model relates to automobile manufacturing field, especially relates to a kind of automobile washing pot seal ring.

Background technology

Windscreen wiper water-injection system before and after current wiper washing system adopts more, windscreen wiper washing system before and after large multi-vehicle-type has, generally all be equipped with two water spray motors on Windshield Washer, feedback vehicle washing system fault is arranged on automotive aftermarket at present more, remove outside the customer complaints such as rain shaving electrical machine fault, windshield wiper are unclean, the Windshield Washer fault is also a major failure of customer complaint, and the Main Patterns of Windshield Washer fault is the water spray electrical fault.The major cause that causes this fault is that current car and light-duty micro-objective windscreen wiper Windshield Washer motor adopt single lip rubber seal more, this type of ring structure is simple, but water resistance is good not, after long-term the use, the easy dilatating and deformable of seal ring lip, water tightness reduces greatly, makes water spray motor internal waterproof bad, and the motor entering water corrosion was lost efficacy.

Summary of the invention

The utility model purpose is to provide a kind of automobile washing pot seal ring that strengthens water spray motor water resistance.

For achieving the above object, the utility model can be taked following technical proposals:

Automobile washing pot seal ring described in the utility model, comprise the seal ring body be sleeved on Windshield Washer water spray motor shaft; In described seal ring body inner peripheral surface upper and lower position, place is provided with respectively the first internal projecting ring, the second internal projecting ring, and in seal ring body outer peripheral face upper and lower position, place is provided with respectively the first outer bulge loop, the second outer bulge loop; In seal ring body bottom, outer peripheral face is provided with ring stiffener.

Described the first internal projecting ring, the second internal projecting ring cross section are for being tilted to upper setting; The described first outer bulge loop, the second outer bulge loop cross section are triangle.

The utility model advantage is that this device can strengthen the sealing property of water spray motor greatly, makes and seals more stability and durability, greatly reduces fault rate.
