Magnetic sunshade curtain anti-sagging structure assembly

Abstract

This utility model relates to a magnetic sunshade curtain anti-sagging structure assembly, including a curtain fabric and glass conductive wires. Multiple glass conductive wires are evenly spaced along the front-to-back direction of the sunroof glass and are either embedded within the sunroof glass or plated onto its inner surface. Multiple radially magnetized permanent magnet strips are integrally sewn evenly spaced along the front-to-back direction onto the inner or upper surface of the curtain fabric. By controlling the magnetic field on the side of the curtain fabric, Ampere forces are generated on the current in the glass conductive wires, causing them to attract or repel each other. The attraction helps to lift the curtain fabric and prevent sagging.

Description

Technical Field

[0001] This utility model relates to the field of sunshade curtains, specifically a magnetic sunshade curtain anti-sagging structure assembly. Background Technology

[0002] In sunroof sunshade technology, in pursuit of comfort, performance, and aesthetics, sunshades used on large-span or large-sized sunroofs tend to sag under their own weight, affecting aesthetics and taking up roof space. Current domestic manufacturers use a structure similar to plastic strips spanning the sunshade to reinforce the fabric and prevent sagging. However, integrating these plastic strips with the fabric affects its overall flatness and leads to aging and failure after prolonged use on the sun-facing side, causing problems such as winding and jamming. Summary of the Invention

[0003] This utility model provides a magnetic anti-sagging structure assembly for sunshade curtains that is simple in structure and can take into account both the aesthetics of the curtain fabric and the ability to prevent sag when rolled up.

[0004] The technical solution adopted by this utility model is: a magnetic sunshade curtain anti-sagging structure assembly, including a curtain fabric, characterized in that: it includes glass conductive wires, multiple glass conductive wires are evenly spaced and built into the sunroof glass or plated on the inner surface of the sunroof glass along the front and back direction, and multiple radially magnetized permanent magnet strips are integrally sewn evenly spaced along the front and back direction of the curtain fabric inside or on the upper surface of the curtain fabric.

[0005] The two adjacent glass conductive wires are connected to currents flowing in different directions.

[0006] The glass conductive wire is connected to the vehicle's low-voltage battery power supply or the sunroof's built-in power supply.

[0007] Multiple conductive wires are integrally sewn at even intervals along the front-to-back direction of the curtain on the inner or upper surface of the curtain.

[0008] The multiple conductive wires of the fabric are connected to currents in the same direction, or two adjacent conductive wires of the fabric are connected to currents in different directions.

[0009] A magnetic sunshade curtain anti-sagging structure assembly includes a curtain fabric, characterized in that: it includes a magnetic film, multiple magnetic films are evenly spaced along the front-to-back direction of the sunroof glass and are built into the sunroof glass or disposed on the inner surface of the sunroof glass, and multiple radially magnetized permanent magnet strips or multiple magnetic films are integrally sewn evenly spaced along the front-to-back direction of the curtain fabric inside or on the upper surface of the curtain fabric.

[0010] The permanent magnet strips and magnetic films are magnetized in the same direction, or the magnetic films on the sunroof glass are magnetized in different directions at intervals.

[0011] The beneficial effects of this invention are as follows: A glass conductive wire is installed inside or on the lower surface of the skylight glass to control the direction of current flow, forming a magnetic field on the glass side. A radially magnetized permanent magnet strip is installed inside or on the upper surface of the curtain. The magnetic field on the curtain side formed by the permanent magnet strip corresponds to the magnetic field on the glass side. The magnetic field on the curtain side generates an Ampere force on the current in the glass conductive wire, attracting or repelling each other. The attraction helps lift the curtain and prevent sagging, or the attraction and repulsion alternate to lift and press down the curtain, ensuring its suspension and preventing sagging, while also facilitating smooth curtain unwinding. Alternatively, a curtain conductive wire can be used instead of a permanent magnet strip, achieving the same attraction or repulsion effect. A magnetic film can also be used; when the magnetization direction is consistent, an overall magnetic surface can be formed, enhancing the interaction between the skylight glass and the curtain, ensuring sufficient attraction and lifting of the curtain. Furthermore, magnetic films with opposite magnetization directions are spaced on the glass, achieving alternating attraction and repulsion when corresponding to the magnetic fields generated by the permanent magnet strip, conductive wire, or magnetic film on the curtain.

[0016] The following description, in conjunction with the accompanying drawings and embodiments, provides further details.

[0017] Figure 1 The first embodiment shown describes a magnetic sunshade anti-sagging structure assembly. A glass conductive wire 3 is plated on the lower surface of the sunroof glass 1. Multiple glass conductive wires 3 are evenly spaced along the front-to-back direction of the sunroof glass 1. Two adjacent glass conductive wires are connected to currents flowing in different directions by a low-voltage battery power supply 6 built into the vehicle. Multiple radially magnetized permanent magnet strips 4 are integrally sewn onto the upper surface of the curtain fabric 2, evenly spaced along the front-to-back direction.

[0018] Figure 2 The second embodiment shown describes a magnetic sunshade anti-sagging structure assembly. A glass conductive wire 3 is plated on the lower surface of the sunroof glass 1. Multiple glass conductive wires 3 are evenly spaced along the front-to-back direction of the sunroof glass 1. Adjacent glass conductive wires are connected to currents flowing in different directions by the vehicle's built-in low-voltage battery power supply 6. Multiple curtain conductive wires 5 are integrally sewn onto the upper surface of the curtain fabric 2, evenly spaced along the front-to-back direction. These curtain conductive wires 5 are connected to currents by the vehicle's built-in low-voltage battery power supply 6.

[0019] Figure 3 The third embodiment shown describes a magnetic sunshade curtain anti-sagging structure assembly. Multiple magnetic films 7 are evenly spaced on the lower surface of the sunroof glass 1 along the front-to-back direction of the sunroof glass. Multiple magnetic films are correspondingly arranged on the curtain fabric 2, with the magnetic films having the same magnetization direction.

[0020] Based on Example 3, any magnetic thin film can be replaced with a permanent magnet strip or a conductive wire.

[0021] Based on the above embodiments, the two sides of the curtain are constrained in the grooves of the guide rail. The magnetic attraction or repulsion only ensures that the curtain does not sag on the plane. The curtain will not come off the groove constraint of the guide rail and adhere to the glass or come off the groove constraint downward.

[0022] In the above embodiments, connecting the conductive wire to the vehicle's built-in or sunroof's built-in power supply is a simple process of generating a magnetic field through energization, and the techniques for controlling the current direction are existing technologies. Vehicle low voltage is typically 12V or 24V, which is a safe voltage, making it safe for the curtains and glass to be electrified.
