Description

Detachable flexible windscreen wiper shaft sheath and mounting structure thereof

Technical Field

The utility model relates to an automobile windscreen wiper field, concretely relates to detachable flexible windscreen wiper axle sheath and mounting structure thereof.

Background

With the improvement of the living standard of substances, the requirements of consumers on the quality of automobiles are higher and higher, and people pay more and more attention to the perception quality, water tightness, NVH performance and the like of the automobiles. The area where the front windshield glass, the lower window trim, and the wiper are matched is not the most important surface, but is more and more important in the current design.

The design scheme of traditional motorcycle type here is generally to design the via hole that supplies the windscreen wiper axle to pass through under the windscreen on the decorative board to leave great clearance, be favorable to the windscreen wiper like this and easily pass through when the assembly, and avoid mutual interference in the windscreen wiper motion process.

However, a large cavity is formed between the wiper shaft and the via hole in the lower decorative plate of the windshield, so that the internal structure is easy to see, rainwater easily flows into the cavity from the hole, and then possibly flows onto a wiper transmission mechanism and a motor, so that the problems of corrosion, circuit failure and the like of the wiper are easily caused.

Therefore, a rubber sheath is designed to be mounted on a wiper shaft in common vehicle types, but the scheme has the defect of poor appearance perception quality, so that most luxury vehicles are integrally molded with a rubber sheath structure on a decorative plate under a windshield, but the scheme adopts secondary injection molding, so that the part size is large, the mold cost is high, and the cost control is not facilitated.

The utility model provides a mounting structure of detachable flexible windscreen wiper axle sheath, the sheath main part passes through annular buckle installs and establishes on the installation via hole of decorative board under the windscreen, the windscreen wiper axle is followed wear-resisting ring's center passes.

Preferably, the wiper shaft is in clearance fit with the wear-resistant ring, so that smooth operation of the wiper shaft is ensured, and other impurities can be prevented from entering an inner area from the position.

Preferably, the lower decorative plate of the windshield sinks along the edge position of the mounting through hole to form a second groove, and the annular buckle is clamped on the lower edge of the second groove.

Compared with the prior art, the utility model, have following advantage:

1. the windscreen wiper shaft sheath is arranged on the lower decorative plate of the windscreen wiper, so that the appearance perception quality is effectively improved, and rainwater can be prevented from directly impacting a windscreen wiper transmission mechanism and a motor;

2. due to good tightness, NVH is favorably improved;

3. the size deviation of the windscreen wiper in the installation or movement process can be well absorbed through the telescopic corrugations, and the long-term movement of the windscreen wiper to damage the sheath can be avoided through the wear-resisting rings;

4. the sheath is connected with the lower decorative plate of the air window through the annular buckle, and the installation and the disassembly are convenient;

5. the sheath is standardized design, can be general on a plurality of motorcycle types, is favorable to reduce cost.
