Bent Axis Assemblies for Shades and Bent Axis Shades

Abstract

The invention provides a bent shaft assembly (1) for a sunshade, the bent shaft assembly (1) comprising: a bent shaft (20); a plurality of sleeves (10), the plurality of sleeves (10 ) is set on the bent shaft (20), and a plurality of first teeth (11) are provided at the first end, and a plurality of second teeth (12) are provided at the second end, wherein adjacent sleeves pass through A plurality of said first teeth (11) and a plurality of said second teeth (12) are mutually meshed and coupled to each other; wherein, said first teeth (11) and said second teeth (12) are respectively horizontal formed across the wall thickness of said first end and said second end of said sleeve (10). The present invention also relates to a bent axis sunshade comprising the above bent axis assembly. Utilizing the bent shaft assembly of the present invention can improve the strength and fit precision, reduce friction and running noise, and can adapt to the application environment with larger stroke and larger curvature.

Description

technical field [0001] The invention relates to the field of sunshades, in particular to a bent shaft assembly for a sunshade and a bent shaft sunshade comprising the bent shaft assembly. Background technique [0002] In order to block the sun's rays, the skylights of cars, boats or sunrooms are usually equipped with sunshades or sunshades. For larger-sized sunroofs, such as panoramic sunroofs in cars, sunshades that can be rolled up and stored are widely used. In the stowed state, the curtain is wound on the shaft of the sunshade. However, in common designs of existing sunshades, the shaft of the sunshade is usually straight. As a result, such products take up more headspace when installed on skylights with curvature. [0003] In addition, in the prior art, there is also a shaft of a sunshade that is curved, which can reduce the head space occupied by the sunshade and improve user comfort. The bent shaft assembly of this product generally includes a bent shaft, a multi-...

AI Technical Summary

Problems solved by technology

However, in the teeth of this two-layer structure, the teeth are relatively thin and weak

Especially for a relatively long sunshade, the winding torque is large, and the connection strength of the sleeve may be insufficient, which may easily cause the teeth of the sleeve to break, etc.

At the same time, for a curved shaft with a large curvature, the included angle between two adjacent sleeves will be relatively large. In this way, the fit between the teeth of the sleeves will become worse, and the gap will become larger, which will easily cause larger gaps when the sleeve rotates. high friction and noise

Therefore, this two-layer tooth structure sleeve cannot adapt to the curved shaft with large curvature.
