Description

Technical Field

[0001] The invention relates to a rolling curtain device, in particular to a rolling curtain device which can be installed on a window or skylight of a motor vehicle to provide a sunshade function. Background Art

[0002] An electric roller blind device currently used in motor vehicles to provide a sunshade function is installed at the window or sunroof of the motor vehicle, and a frame is installed on the inner side of the window or the inner side of the sunroof. The frame has two parallel guide rails, and the two guide rails are respectively arranged on opposite sides of the window or the sunroof. The electric roller blind device includes a roller blind and a drive component. The roller blind has a cloth curtain and a cloth curtain roller shaft that can automatically roll up the cloth curtain. The cloth curtain roller shaft is installed on the window outside of the frame. The drive component has a drive component that can be driven by a motor. The drive component is connected to the movable edge of the cloth curtain, so that the drive component can drive the cloth curtain to unfold and fold with a drive arm driven by the motor.

[0003] In order to ensure that the curtain moves smoothly during the process of unfolding and folding, and to ensure that the curtain is supported by the frame after unfolding, the existing rolling curtain device is provided with a hard guide edge on both long sides of the curtain. The hard guide edge can move along the guide rail, and the hard guide edge is limited in the curtain guide groove of the guide rail, so that the long sides of the curtain are supported by the guide rail and prevented from detaching from the guide rail.

[0004] In the above-mentioned existing rolling curtain device, the purpose of preventing the long sides of the curtain from escaping from the guide rail can be achieved by limiting the hard guide edges of the long sides of the curtain in the curtain guide groove of the guide rail. However, the hard guide edges of the long sides of the curtain have a certain hardness based on the requirement of being wound on the curtain reel, but still have to be flexible. Therefore, when the curtain is pulled and unfolded, the hard guide edges of the long sides of the curtain move along the guide rail, and the hard guide edges may still fall out of the guide rail. Especially for curtains with a larger area, the unfolded curtains are prone to drooping due to their own weight, which makes it easy for the hard guide edges to fall out of the guide rail. Further improvements are needed in this regard. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a rolling curtain device to solve the problem that the hard guide edges on both sides of the long sides of the cloth curtain of the existing rolling curtain device are insufficient in preventing the hard guide edges from falling off the guide rail.

[0006] The technical solution proposed by the present invention is to provide a rolling curtain device, which is used to be installed in a frame with a window, and the rolling curtain device includes a rolling curtain, the rolling curtain has a curtain roller and a curtain connected to the curtain roller, and the two guide edges of the curtain can move along two guide rails on opposite sides of the window respectively, wherein:

[0007] The two guide edges of the curtain are each provided with a plurality of guide through holes which are arranged in a straight line with equal spacing parallel to the length direction of the guide rail;

[0008] The rolling curtain device includes two spiral bars and a driving mechanism. The two spiral bars are respectively installed in the two guide rails, and the two spiral bars are respectively spirally passed through the guide through holes of the two guide edges of the cloth curtain. The driving mechanism connects the two spiral bars and can drive the two spiral bars to rotate forward and reverse. The rotating two spiral bars can synchronously change the length of the spiral bars screwed on the two guide edges to drive the cloth curtain to unfold and fold.

[0009] In the rolling curtain device as described above, the driving mechanism and the curtain roller are respectively mounted on opposite side ends of the frame along the guide rail, one end of the spiral strip facing the curtain roller is a spiral head end, and the other end of the spiral strip is a connecting end. The two spiral strips are connected to the driving mechanism via the connecting ends, and the spiral head ends of the two rotating spiral strips can be sequentially screwed into the guide through-holes of the guide edge or screwed out of the guide through-holes.

[0010] In the rolling blind device as described above, the wire diameter of the spiral strip is smaller than the hole diameter of the guide through hole, and the pitch of the spiral strip is equal to the center distance between every two adjacent guide through holes.

[0011] In the rolling blind device as described above, the driving mechanism has two motors, and each of the motors is connected to a corresponding connecting end of the spiral strip.

[0012] In the rolling blind device as described above, the driving mechanism comprises a motor and a gear train transmission assembly connected to the motor, and the gear train transmission assembly is connected to the connecting ends of the two spiral strips.

[0013] In the rolling curtain device as described above, the curtain has a movable side strip that can move along the two guide rails; the rolling curtain device also includes a curtain auxiliary unfolding mechanism, which is connected to the movable side strip and provides a force to pull the curtain when the curtain is unfolded.

[0014] In the rolling curtain device as described above, the curtain auxiliary unfolding mechanism includes a wire winding shaft, at least one flexible wire and an auxiliary motor. The wire winding shaft can be rotatably mounted on the other side of the window relative to the curtain rolling shaft. The two ends of the flexible wire are respectively connected to the wire winding shaft and the movable side strip. The auxiliary motor is connected to the wire winding shaft. The auxiliary motor can drive the wire winding shaft to rotate forward and reverse, and can assist in driving the curtain to unfold and fold through the flexible wire.

[0015] In the rolling curtain device as described above, the rolling curtain device has a curtain support rod, which is arranged in the frame and located between the window and the curtain roller. The curtain extends from the curtain roller and passes around the curtain support rod and is then screwed to the two spiral strips.

[0016] In the rolling curtain device as described above, the curtain has a soft cloth material, the guide edge has a colloid fixed to the long edge of the soft cloth material by heat pressing, and the guide perforation passes through the long edge of the soft cloth material and fixes the colloid on the long edge.

[0017] In the rolling curtain device as described above, the curtain has a soft fabric, the guide edge has a film fixed to the long edge of the soft fabric, and the guide perforation passes through the long edge of the soft fabric and the film fixed to the long edge.

[0018] The beneficial effect that can be achieved by the present invention is that the rolling curtain device utilizes spiral strips respectively installed in two guide rails of the frame to screw together two guide edges of the curtain with guide holes. The spiral strips are restricted in the guide rails. The two spiral strips driven to rotate by the driving mechanism can change the positions of the guide holes screwed on the two guide edges of the curtain to drive the curtain to unfold or fold, and the spiral strips located in the guide rails are used to connect the guide edges of the curtain to effectively prevent the guide edges of the curtain from detaching from the guide rails.

[0019] The rolling curtain device of the present invention can also be provided with a curtain auxiliary unfolding mechanism, which is connected to the movable edge strip of the curtain. During the unfolding process of the curtain, the curtain auxiliary unfolding mechanism provides auxiliary force to pull the curtain to unfold, thereby offsetting a part of the retracting force of the curtain roller on the curtain, so that the movement of the two spiral strips driven to rotate to drive the curtain to unfold is smoother.

[0020] The rolling curtain device of the present invention can also add a support rod between the frame, the window and the curtain roller, so that the curtain pulled out from the curtain roller can be flattened by the support rod first, and then enter the guide rail to be screwed to the spiral strip, thereby allowing the curtain to be smoothly driven by the two spiral strips to unfold and fold.

[0060] The following further describes the technical means adopted by the present invention to achieve the predetermined purpose of the invention in conjunction with the accompanying drawings and preferred embodiments of the present invention.

[0061] The rolling curtain device of the present invention is suitable for window sunshades or sunroof sunshades of motor vehicles, or other products that use cloth curtains to provide opening and closing functions. Figure 1 and Figure 2 As shown, two preferred embodiments of the rolling curtain device 2 of the present invention are disclosed. The rolling curtain device 2 is used to be installed in a frame 1 having a window 11. The frame 1 can be set in the body of a motor vehicle and is located on the side of the window or sunroof. An axial direction is defined in the window 11 of the frame 1. The frame 1 has a first side 101 and a second side 102 on opposite sides along the axial direction. The frame 1 has a guide rail 12 on opposite sides of the window 11 parallel to the axial direction, that is, the length direction of the guide rail 12 is parallel to the axial direction. Each of the guide rails 12 has a curtain guide groove 121 opening toward the window 11, and the width of the opening of the curtain guide groove 121 is smaller than the width of the internal space of the curtain guide groove 121. The structure of the frame 1 and its guide rail 12 belongs to the prior art and will not be repeated here.

[0062] like Figure 1 and Figure 2As shown, the rolling curtain device 2 includes a rolling curtain 20, two spiral strips 30 and a driving mechanism 40. The rolling curtain 20 includes a curtain reel 21 and a curtain 22. The curtain reel 21 includes a shaft tube and a retractor installed in the shaft tube. The curtain reel 21 is an existing product. The curtain roller 21 can be rotatably mounted on the first side 101 of the frame 1, one side end of the curtain 22 is connected to the curtain roller 21, and the other side end of the curtain 22 has a movable side strip 223. The curtain 22 can be automatically rolled up on the curtain roller 21 and folded, and the curtain 22 can be pulled out from the curtain roller 21 and unfolded. The two opposite side edges of the curtain 22 parallel to the axial direction are respectively a guide edge 221. When the curtain 22 is unfolded and folded, the two guide edges 221 can respectively extend into the curtain guide groove 121 of the guide rail 12 at the corresponding position and can move along the guide rail 12. The two guide edges 221 are respectively provided with a plurality of guide through holes 222 arranged in a straight line with equal intervals along the axial direction.

[0063] like Figure 3 As shown, the cloth curtain 22 can be made of a soft cloth material 220 such as a random-grain cloth or other woven cloth, and the guide edge 221 of the cloth curtain 22 has a colloid 221a fixed to the long edge 2201 of the soft cloth material 220 parallel to the axial direction by heat pressing, and the guide through hole 222 passes through the long edge 2201 of the soft cloth material 220 and the colloid 221a fixing the long edge 2201. Or, as Figure 4 As shown, the guide edge 221 has a film 221b fixed to the long side 2201 of the soft fabric 220 parallel to the axial direction by means of adhesion or sewing, and the guide through hole 222 passes through the long side 2201 of the soft fabric 220 and the film 221b fixed to the long side 2201. By combining the guide edge 221 with the long side 2201 of the soft fabric 220 by the colloid 221a or the film 221b, the guide edge 221 of the curtain 22 has appropriate hardness and bending elasticity, so that the soft fabric 220 and the guide edge 221 of the curtain 22 can be wound together on the curtain reel 21, and the long side 2201 of the soft fabric 220 is not easy to fall off and has good wear resistance after combining the colloid 221a or the film 221b.

[0064] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the two spiral strips 30 are respectively installed in the two guide rails 12, and the two spiral strips 30 respectively spiral through the guide holes 222 of the two guide edges 221 of the curtain 22. The two spiral strips 30 can be synchronously driven to rotate to change the length of the two guide edges 221 screwed on the curtain 22, thereby driving the curtain 22 to unfold and fold. It is defined that the two spiral strips drive the curtain 22 to move in the unfolding direction as positive rotation, and the two spiral strips drive the curtain 22 to move in the folding direction as reverse rotation. It should be further explained that the two spiral strips 30 are respectively screwed to the two guide edges 221 on the opposite sides of the cloth curtain 22, so the two spiral strips 30 are synchronously driven to rotate forward (reverse) means that the two spiral strips 30 rotate in opposite directions at the same time, that is, when the forward rotation of one spiral strip 30 is clockwise, the forward rotation of the other spiral strip 30 is counterclockwise, thereby synchronously driving the two guide edges 221 of the cloth curtain 22 to move in the same direction; similarly, when the reverse rotation of one spiral strip 30 is counterclockwise, the reverse rotation of the other spiral strip 30 is clockwise.

[0065] In the above, one end of the two spiral strips 30 each has a spiral head end 31, and the other end of the two spiral strips 30 is a connecting end 32. The spiral head end 31 is located at one end of the spiral strip 30 adjacent to the curtain roller 21 and is a free end. The connecting end 32 is located at the other end of the spiral strip 30 away from the curtain roller 21 and extends out of the guide rail 12. The connecting end 32 is located at the center line of the spiral strip 30. The two spiral strips 30 can be driven to rotate synchronously in the positive direction. And reverse rotation, wherein, through the forward rotation of the two spiral strips 30, the spiral head end 31 can be screwed from a guide hole 222 in the guide edge 221 of the curtain 22 into the next guide hole 222 to drive the curtain 22 to unfold, and, through the reverse rotation of the two spiral strips 30, the spiral head end 31 is sequentially detached from the guide hole 222 in the guide edge 221 of the curtain 22, and the curtain 22 is automatically rolled up by the curtain roller 21, so that the curtain 22 is folded.

[0066] like Figure 5 and Figure 6 As shown, in this preferred example, the wire diameter of the spiral strip 30 is smaller than the hole diameter of the guide hole 222, and the pitch of the spiral strip 30 is equal to the center distance between every two adjacent guide holes 222, thereby making it easy for the spiral strip 30 to pass through the guide hole 222 of the curtain 22 and detach from the guide hole 222.

[0067] like Figure 1 , Figure 2As shown, the driving mechanism 40 is installed on the second side 102 of the frame 1, so that the driving mechanism 40 and the curtain roller 21 are respectively located on the opposite sides of the frame 1 along the axial direction. The driving mechanism 40 is connected to the connecting ends 32 of the two spiral strips 30 and can drive the two spiral strips 30 to rotate forward and reverse synchronously. The spiral head ends 31 of the two synchronously rotating spiral strips 30 can be sequentially screwed into the guide through hole 222 of the guide edge 221 or screwed out of the guide through hole 222, thereby changing the length of the screws on the two guide edges 221 to drive the curtain 22 to unfold and fold.

[0068] like Figure 1 As shown, the driving mechanism 40 may have two motors 41, each motor 41 corresponding to a connecting end 32 connected to a spiral strip 30. Alternatively, as Figure 2 As shown, the driving mechanism 40 has a motor 41 and a gear transmission assembly 42 connected to the motor 41, and the gear transmission assembly 42 is used to connect the connecting ends 32 of the two spiral bars 30, replacing the aforementioned mechanism in which the two motors 42 drive the two spiral bars 30 respectively. The gear transmission assembly 42 can be a pulley set or other equivalent gear transmission assembly.

[0069] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, regarding the use of the aforementioned rolling curtain device 2, when the cloth curtain 22 is folded, the cloth curtain 22 is wound on the cloth curtain reel 21, so that the window 11 of the frame 1 is not covered. When the cloth curtain 22 is unfolded, the driving mechanism 40 drives the two spiral strips 30 to rotate synchronously in the positive direction, and the spiral head ends 31 of the rotating two spiral strips 30 are screwed from one guide through hole 222 in the guide edge 221 of the cloth curtain 22 into the next guide through hole 222, so that the spiral strips 30 increase the length of the screw-connected guide edge 221, thereby driving the cloth curtain 22 to unfold and cover the window 11 of the frame 1.

[0070] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, when folding, the driving mechanism 40 drives the two spiral strips 30 to rotate in the opposite direction, so that the spiral head ends 31 are sequentially disengaged from the guide holes 222 in the guide edge 221 of the curtain 22, and under the action of the curtain roller 21 automatically rolling up the curtain 22, the curtain 22 is gradually wound around the curtain roller 21 to the folded state.

[0071] like Figure 1 and Figure 7In the preferred embodiment shown, the rolling curtain device 2 can also be provided with a support rod 23 between the window 11 and the curtain roller 21 in the frame 1, so that after the curtain 22 of the rolling curtain 20 extends from the curtain roller 21, it first passes over the support rod 23 to be leveled, and then extends into the guide rail 12 and is screwed to the two spiral strips 30. In this way, the curtain 22 can be smoothly driven by the two spiral strips 30 to unfold and fold.

[0072] The combination of the two spiral strips 30 driven by the driving mechanism 40 and the guide holes 222 of the two guide edges 221 of the curtain 22, together with the curtain roller 21 connected to the curtain 22, is sufficient to enable the curtain 22 to unfold and fold. Figure 8 and Fig. 9 As shown, the rolling curtain device 2 can also be provided with a curtain auxiliary unfolding mechanism 50, and the curtain auxiliary unfolding mechanism 50 is connected to the movable side strip 223 of the curtain 22. During the unfolding process of the curtain 22, the curtain auxiliary unfolding mechanism 50 provides an auxiliary force for pulling the curtain 22 to unfold, thereby offsetting a part of the retracting force of the curtain roller 21 on the curtain 22, so that the movement of the two spiral strips 30 driven to rotate to drive the curtain 22 to unfold is smoother.

[0073] like Figure 8 and Fig. 9 In the preferred embodiment shown, the curtain auxiliary unfolding mechanism 50 includes a wire winding shaft 51, at least one flexible wire 52 and an auxiliary motor 53. The wire winding shaft 51 can be rotatably mounted on the second side 102 of the frame 1. The two ends of the flexible wire 52 are respectively connected to the wire winding shaft 51 and the movable side strip 223. In the preferred embodiment shown in the figure, two flexible wires 52 are used to be connected to the wire winding shaft 51 and the movable side strip 223 in an interval and parallel arrangement to provide a balancing force to the movable side strip 223. The auxiliary motor 53 is connected to the wire winding shaft 51, and the auxiliary motor 53 can drive the wire winding shaft 51 to rotate forward and reverse, so that the rotating wire winding shaft 51 can wind and release the flexible wire 52. When the wire winding shaft 51 rotates forward, the flexible wire 52 wound around it can exert a pulling force on the movable side strip 223 of the curtain 22, thereby assisting the two spiral strips 30 in pulling the curtain 22 to unfold. When the wire winding shaft 51 rotates reversely, the wire winding shaft 51 releases the flexible wire 52, so that the curtain 22 is automatically retracted under the action of the rewinding force of the curtain winding shaft 21.

[0074] The above is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician in the field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
