[0002] With the rapid development of the automobile industry, cars generally have sunroofs. When the sunroof is opened, it not only provides sufficient ventilation, but also has good lighting performance. In addition, ordinary sunroofs have a low manufacturing cost and are widely popular.

[0003] The sunroof opening is usually equipped with a sunshade and an insect-proof net. By unfolding the sunshade, direct sunlight can be blocked from entering the cab, and by unfolding the insect-proof net, mosquitoes can be prevented from entering the cab, thereby improving the riding comfort of the occupants.

[0004] In the related art, sunshades and insect-proof nets are arranged in upper and lower layers. Each sunshade and insect-proof net has two sets of slide rails or one set of double-layer slide rails to realize unfolding and retracting movements. The corresponding handles are used to manually drive the relevant beams and curtains to slide in the slide rails to realize the unfolding or retracting of the sunshade or insect-proof net.

[0005] However, the sunshade and insect screen use two sets of slide rails or one set of double-layer slide rails. There are the following problems:

[0047] The embodiments of the present application provide a sunroof electric roller blind with a single-layer guide rail and a vehicle, which can solve the problem that the sunshade and insect-proof net in the related art use two sets of slide rails or one set of double-layer slide rails, which has a relatively complex structure and high cost.

[0048] See also Figure 1 As shown, in a first aspect, an embodiment of the present application provides a sunroof electric roller blind with a single-layer guide rail, comprising:

[0049] The slide rail assembly 10 includes two single-layer guide rails 11 that are parallel to each other and spaced apart, and a crossbeam 12 that is slidably connected to the two single-layer guide rails 11. The crossbeam 12 is located between the two single-layer guide rails 11, one end of the crossbeam 12 is slidably connected to one of the single-layer guide rails 11, and the other end of the crossbeam 12 is slidably connected to the other single-layer guide rail 11.

[0050] The insect-proof rolling curtain 20 includes an insect-proof net reel 21 located at one end of the two single-layer guide rails 11, the insect-proof net reel 21 and the cross beam 12 are parallel to each other, and an insect-proof net 22 wound on the insect-proof net reel 21 and connected to the cross beam 12. One end of the insect-proof net 22 is a fixed end and connected to the insect-proof net reel 21, and the other end of the insect-proof net 22 is a free end and connected to the cross beam 12. A coil spring is provided in the insect-proof net reel 21, and the coil spring is used to drive the insect-proof net reel 21 to rotate to automatically reel up the insect-proof net 22.

[0051] The sunshade roller blind 30 includes a sunshade roller shaft 31 located at the other end of the two single-layer guide rails 11, the sunshade roller shaft 31 and the cross beam 12 are parallel to each other, and a sunshade cloth 32 wound on the sunshade roller shaft 31 and connected to the cross beam 12. One end of the sunshade cloth 32 is a fixed end and connected to the sunshade roller shaft 31, and the other end of the sunshade cloth 32 is a free end and connected to the cross beam 12. A coil spring is provided in the sunshade roller shaft 31, and the coil spring is used to drive the sunshade roller shaft 31 to rotate to automatically retract the sunshade cloth 32.

[0052] The single-layer guide rail sunroof electric roller blinds of the embodiment of the present application are provided with an insect-proof roller blind 20 at one end of the two single-layer guide rails 11, and a sunshade roller blind 30 is provided at the other end of the two single-layer guide rails 11. The sunshade roller blind 30 and the insect-proof roller blind 20 are relatively spaced apart and share the two single-layer guide rails 11, which simplifies the structure of the slide rail assembly and significantly reduces the manufacturing cost of the slide rail assembly.

[0053] The insect-proof net 22 of the insect-proof roller blind 20 and the sunshade curtain 32 of the sunshade roller blind 30 are both connected to the crossbeam 12 that is slidably connected to the two single-layer guide rails 11. When the crossbeam 12 slides on the two single-layer guide rails 11, the opening ratio of the insect-proof net 22 and the sunshade curtain 32 can be freely adjusted, thereby freely adjusting the amount of light entering the skylight.

[0054] The light transmittance of the insect-proof net 22 of the embodiment of the present application is 50%, and the light transmittance of the sunshade curtain 32 is 5%. The opening and closing of the insect-proof net 22 and the sunshade curtain 32 have three states, which are as follows:

[0055] The crossbeam 12 slides on the two single-layer guide rails 11 toward the direction approaching the sunshade curtain roller 31. When the sunshade curtain roller 31 blocks the crossbeam 12, the insect-proof net 22 is in a fully unfolded state, and the sunshade curtain cloth 32 is in a fully retracted state. At this time, the light transmittance at the skylight is 50%, and the ventilation efficiency is the highest.

[0056] The crossbeam 12 slides on the two single-layer guide rails 11 toward the direction approaching the insect-proof net reel 21. When the insect-proof net reel 21 blocks the crossbeam 12, the insect-proof net 22 is in a fully retracted state, the sunshade curtain 32 is in a fully unfolded state, the light transmittance at the skylight is 5%, and the sunshade effect is best.

[0057] When the crossbeam 12 moves on the two single-layer guide rails 11 to any position between the sunshade curtain reel 31 and the insect-proof net reel 21, the insect-proof net 22 and the sunshade curtain 32 are both in a partially open and partially closed state. The crossbeam 12 is in different positions, and the light transmittance at the skylight can be freely adjusted from 5% to 50%, and the ventilation efficiency can also be freely adjusted accordingly.

Guide chutes 15 for slidably connecting cross beams 12 are provided on both of the two single-layer guide rails 11 of the electric skylight roller blind, and the openings of the guide chutes 15 on the two single-layer guide rails 11 face each other. Sliders 13 for slidably connecting with the guide chutes 15 of each single-layer guide rail 11 are respectively provided at both ends of the cross beam 12, and the sliders 13 slide along the length direction of the single-layer guide rail 11 within the guide chutes 15.

[0059] In the embodiment of the present application, guide chutes 15 for slidably connecting cross beams are provided on one side where the two mutually parallel single-layer guide rails 11 are close to each other. Each single-layer guide rail 11 has only one layer of guide chutes 15, so it is called a single-layer guide rail 11. Compared with using upper and lower two-layer slide rails or opening upper and lower two-layer chutes on one slide rail, the structure of the single-layer guide rail 11 is more simplified, which is convenient for processing and manufacturing and has a lower cost.

[0060] Sliders 13 for slidably connecting with the guide chutes 15 of each single-layer guide rail 11 are respectively provided at both ends of the cross beam 12. A card slot 14 for connecting the sliders 13 is provided at the top of the cross beam 12, and the card slot 14 extends along the length direction of the cross beam 12. The sliders 13 enable the cross beam 12 to move along the length direction of the guide chutes 15 of each single-layer guide rail 11, so as to keep the cross beam 12 sliding along a set track on the single-layer guide rail 11.

[0061] In some alternative embodiments: Refer to Figure 1 、 Figure 5 and Figure 6 As shown in the figure, an embodiment of the present application provides an electric skylight roller blind with a single-layer guide rail.

[0065] A limiting notch 134 matched with the limiting convex edge 16 is provided at the connection between the lower elastic arm 133 and the plug-in arm 131. The limiting convex edge 16 is located in the limiting notch 134. The limiting convex edge 16 and the limiting notch 134 cooperate with each other to limit the slider 13 from escaping from the guide groove 15, so that the slider 13 can still reliably slide in contact with the guide groove 15 after wear, thereby improving the positioning accuracy in the width direction of the vehicle.
