Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a sunshade device and vehicle. Background Technology

[0002] Sunroof sunshades on vehicles block out sunlight when open. In related technologies, the opening and closing of sunroof sunshades can be achieved in two ways: one relies on a motor driving a flexible shaft (connected to the front end of the sunshade fabric) and a spring or coil spring structure on the roller tube. The flexible shaft is prone to producing abnormal noise during operation and is structurally heavy, reducing the user experience. The other method involves a motor driving a winding drum, which in turn drives a pull cord, which in turn moves a slider to unfold the sunshade. When retracting, the motor drives the curtain roller to retract the sunshade. This latter method is unstable and has limited curtain tension, making it prone to wrinkling. Utility Model Content

[0003] This application provides a sunshade device and vehicle, which has a simple and lightweight structure and allows for smoother movement of the curtain.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include:

[0005] In a first aspect, embodiments of this application provide a sunshade device, including a frame, a roller assembly, a movable part, a curtain fabric, and a drive assembly. The frame includes a first beam and a second beam, which are arranged opposite to each other in a left-right direction. The roller assembly is connected between the first beam and the second beam. In the left-right direction, the movable part has a first end and a second end arranged opposite to each other, the first end being slidably connected to the first beam, and the second end being slidably connected to the second beam. One end of the curtain fabric is wound around the roller assembly, and the other end is connected to the movable part. The drive assembly includes a drive mechanism, a winding wheel, and a pull cord, the drive end of which is connected to the winding wheel. The pull wires include a first pull wire, a second pull wire, and a third pull wire. One end of the first pull wire is wound around the reel, and the other end of the first pull wire is connected to the first end. One end of the second pull wire is connected to the first end, and a portion of the second pull wire is located on the side of the first end away from the drive mechanism. The other end of the second pull wire is connected to the second end after being turned. One end of the third pull wire is connected to the second end, and a portion of the third pull wire is located on the side of the second end away from the drive mechanism. The other end of the third pull wire is wound around the reel after being turned. The first pull wire and the second pull wire are wound in opposite directions on the reel.

[0006] The sunshade device proposed in this application has a first pull cord and a third pull cord wound in opposite directions around a winding reel. The first pull cord extends from the winding reel and connects to the first end of the movable part. One end of the second pull cord connects to one end of the movable part and then, after turning, connects to the second end of the movable part. One end of the third pull cord connects to the second end of the movable part and then, after turning, winds around the winding reel.

[0010] Optionally, the sunshade device further includes a first sleeve, a second sleeve, and a third sleeve, wherein the first sleeve is sleeved on the first pull line, the second sleeve is sleeved on the portion of the second pull line located between the third steering member and the second end, and the third sleeve is sleeved on the portion of the third pull line located between the fourth steering member and the winding reel.

[0011] In the above scheme, the setting of the first sleeve, the second sleeve and the third sleeve can improve the positional accuracy of the first pull wire, the second pull wire and the third pull wire, have stronger tolerance, are easier to install, and make the movement of the first pull wire, the second pull wire and the third pull wire smoother.

[0012] Optionally, the sunshade device further includes a fixing base and two fixing tubes. The two fixing tubes are respectively located at both ends of the fixing base in the left-right direction. The driving mechanism is located on the fixing base. The first pull wire and the third pull wire pass through the inner hole of the corresponding fixing tube.

[0013] In the above scheme, after the first pull wire extends from the winding wheel, it passes through the inner hole of the fixed tube. The fixed tube can guide and limit the first pull wire. After the third pull wire extends from the winding wheel, it passes through the inner hole of the fixed tube. The fixed tube can guide and limit the third pull wire.

[0014] Optionally, the inner hole of the fixing tube includes a first sub-segment and a second sub-segment, the first sub-segment being closer to the winding reel than the second sub-segment, and the inner diameter of the first sub-segment being smaller than the inner diameter of the second sub-segment to form a first stepped surface; the end of the first sleeve near the winding reel and the end of the third sleeve near the winding reel respectively abut against the corresponding first stepped surface.

[0015] In the above scheme, the first step surface is used to limit the position of the corresponding first sleeve and third sleeve, thereby improving the accuracy of the first pull wire and the third pull wire.

[0016] Optionally, along the unfolding direction of the curtain, both the first beam and the second beam are provided with sliding grooves; the movable part includes a main body and two sliders, the main body is connected to the other end of the curtain, the two sliders are respectively disposed at both ends of the main body and slide in cooperation with the corresponding sliding grooves, the other end of the first pull line and one end of the second pull line are connected to one of the sliders, and the other end of the second pull line and one end of the third pull line are connected to the other slider.

[0017] In the above scheme, when the drive mechanism drives the winding wheel to rotate, the movement of the first pull line, the second pull line and the third pull line can pull the slider to move along the slide groove, thereby causing the main body to drive the curtain to unfold or rewind.

[0018] Optionally, the slide groove includes a first slide groove and a second slide groove, which are spaced apart along the left-right direction; the slider includes a main body, a first part and a second part, which are both connected to the main body and are spaced apart along the left-right direction, with the first part slidingly engaged with the first slide groove and the second part slidingly engaged with the second slide groove.

[0048] Currently, there are basically two ways to open electric car sunshades. One method relies on a motor to drive a flexible hose with gears. The hose slides and moves the curtain to unfold the sunshade. The sunshade is then retracted by a spring or coil spring mechanism on the roller shutter tube. This structure is relatively complex and costly. The friction between the hose and the guide rail is relatively large, requiring a larger motor. The friction is also prone to producing abnormal noise. Furthermore, this structure is heavy and occupies a large area, resulting in a reduced field of vision.

[0049] One method involves a motor driving a winding drum, which in turn drives a pull cord. The pull cord then moves a slider to unfold the curtain, and during retraction, the motor drives a curtain roller to retract the curtain. However, the rotation of the winding drum is unstable and prone to slipping off the roller, the curtain tension is limited, leading to wrinkles, and the pull cord is prone to friction and noise. Therefore, this application provides a sunshade device that is low-cost, lightweight, operates more smoothly, and has a simpler structure.

[0050] Firstly, reference Figure 1 and Figure 2This application provides a sunshade device, which includes a frame 1, a roller assembly 2, a movable part 3, a curtain fabric 4, and a drive assembly 5. The frame 1 includes a first beam 11 and a second beam 12, which are arranged opposite to each other in the left-right direction X. The roller assembly 2 is connected between the first beam 11 and the second beam 12. In the left-right direction X, the movable part 3 has a first end 31 and a second end 32 arranged opposite to each other. The first end 31 is slidably connected to the first beam 11, and the second end 32 is slidably connected to the second beam 12. One end of the curtain fabric 4 is wound around the roller assembly 2, and the other end is connected to the movable part 3. The drive assembly 5 includes a drive mechanism 51, a winding wheel 52, and a pull cord. The drive end of the drive mechanism 51 is connected to the winding wheel 52. The pull cord includes a first pull cord 531, a second pull cord 532, and a third pull cord 533. One end of the first pull cord 531 is wound around the reel 52, and the other end of the first pull cord 531 is connected to the first end 31. One end of the second pull cord 532 is connected to the first end 31, and a portion of the second pull cord 532 is located on the side of the first end 31 away from the drive mechanism 51. The other end of the second pull cord 532 is connected to the second end 32 after being turned. One end of the third pull cord 533 is connected to the second end 32, and a portion of the third pull cord 533 is located on the side of the second end 32 away from the drive mechanism 51. The other end of the third pull cord 533 is wound around the reel 52 after being turned. The first pull cord 531 and the second pull cord 532 are wound in opposite directions on the reel 52.

[0051] The frame 1 can be connected to the vehicle body. The two ends of the roller assembly 2 are respectively connected to the first beam 11 and the second beam 12. The two ends of the movable part 3 are respectively slidably engaged with the first beam 11 and the second beam 12. One end of the two parts is wrapped around the roller assembly 2, and the other end is connected to the movable part 3. The movable part 3 slides along the first beam 11 and the second beam 12 toward the direction closer to the roller assembly 2. The curtain 4 is rolled up in the roller assembly 2. The movable part 3 slides along the first beam 11 and the second beam 12 toward the direction away from the roller assembly 2, and the curtain 4 unfolds.

[0052] Along the unfolding direction Z of the curtain fabric 4, the drive mechanism 51 and the movable part 3 are located on opposite sides of the roller assembly 2. The first pull cable 531 and the third pull cable 533 are wound in opposite directions on the winding reel 52. The first pull cable 531 extends from the winding reel 52 and connects to the first end 31 of the movable part 3. One end of the second pull cable 532 connects to one end of the movable part 3 and then, after turning, connects to the second end 32 of the movable part 3. One end of the third pull cable 533 connects to the second end 32 of the movable part 3 and then, after turning, winds around the winding reel 52. For example, the portion of the second pull cable 532 connected to the first end 31 is in the same direction as the extension of the first pull cable 531. The other portion of the second pull cable 532, after turning, is parallel to the first pull cable 531, and then the second pull cable 532 is connected to the second end 32. The portion of the third pull cable 533 that connects to the second end 32 extends in the same direction as the portion of the second pull cable 532 that connects to the second end 32. Another portion of the third pull cable 533, after a turn, becomes parallel to the portion of the second pull cable 532 that connects to the second end 32. Then, the third pull cable 533, after another turn, connects to the winding reel 52. Of course, the positional relationship between the first pull cable 531, the second pull cable 532, and the third pull cable 533 can also be other possible forms, as long as they can be tightened and allow the movable part 3 to slide.

[0053] When the drive mechanism 51 drives the winding reel 52 to rotate, one of the first pull cable 531 and the third pull cable 533 unfolds, while the other is wound back into the winding reel 52. The unfolding direction Z of the curtain fabric 4 is the direction in which one end of the curtain fabric 4 moves away from or towards the roller assembly 2. Exemplarily, the drive mechanism 51 can be a motor, and the winding reel 52 is engaged with the drive end of the drive mechanism 51 via gears or splines. For example, if the drive end of the motor has a gear, the inner circumferential wall of the winding reel 52 has meshing teeth that mesh with the gear. In this application, the first pull cable 531 unfolds and the third pull cable 533 is wound back into the winding reel 52 when the drive mechanism 51 rotates forward, and the first pull cable 531 is wound back into the winding reel 52 and the third pull cable 533 unfolds when the drive mechanism 51 rotates in reverse. When the drive mechanism 51 rotates forward, the first pull cable 531 unfolds, the winding wheel 52 winds up the third pull cable 533, the third pull cable 533 pulls the second end 32 of the movable part 3 to slide away from the winding assembly 2, the movable part 3 pulls the second pull cable 532, the second pull cable 532 pulls the first end 31 of the movable part 3 to slide away from the winding assembly 2, so that the curtain 4 unfolds; when the drive mechanism 51 rotates in reverse, the third pull cable 533 unfolds, the winding wheel 52 winds up the first pull cable 531, the first pull cable 531 pulls the first end 31 of the movable part 3 to slide towards the winding assembly 2, the movable part 3 pulls the second pull cable 532, the second pull cable 532 pulls the second end 32 of the movable part 3 to slide towards the winding assembly 2, so that the curtain 4 is wound into the winding assembly 2.

[0054] The sunshade device in this application has a simple structure and is lightweight. During the rolling or unfolding of the curtain 4, the first pull line 531, the second pull line 532, and the third pull line 533 are always taut, which makes the movement of the moving part 3 and the curtain 4 more stable. In addition, the first pull line 531, the second pull line 532, and the third pull line 533 experience less friction during movement, resulting in less noise and a better user experience.

[0055] Optionally, refer to Figure 1 and Figure 2 The sunshade device also includes a first steering component 61 and a second steering component 62. The first steering component 61 is located on the side of the first end 31 away from the roller assembly 2, and the second steering component 62 is located on the side of the second end 32 away from the roller assembly 2. The second pull wire 532 is wound around the first steering component 61, and the third pull wire 533 is wound around the second steering component 62.

[0056] The first steering member 61 and the second steering member 62 are located on the side of the movable part 3 away from the reel assembly 2. The first steering member 61 can be fixed to the end of the first beam 11 away from the reel assembly 2 to steering the second pull line 532 extending from the first end 31 of the movable part 3. The second steering member 62 can be fixed to the end of the second beam 12 away from the reel assembly 2 to steering the third pull line 533 extending from the second end 32 of the movable part 3. The first steering member 61 and the second steering member 62 can be fixed pulleys, with circumferential grooves for the second pull line 532 and the third pull line 533 to be wound around. For example, the first steering component 61 and the second steering component 62 are fixed to the first beam 11 and the second beam 12 respectively, and the rotation axis of the first steering component 61 and the second steering component 62 is perpendicular to the plane defined by the first beam 11 and the second beam 12. That is, the rotation axis of the first steering component 61 and the second steering component 62 extends along the vertical direction Y, where the vertical direction Y is the vertical direction Y of the vehicle, and the left and right direction X can be the left and right direction X of the vehicle, or the left and right direction X can be the front and rear direction of the vehicle.

[0057] Optionally, the sunshade device further includes a third steering member 63 and a fourth steering member 64. The third steering member 63 is located on the side of the first end 31 away from the first steering member 61, and the fourth steering member 64 is located on the side of the second steering member 62. The second pull wire 532 is wound around the third steering member 63, and the third pull wire 533 is wound around the fourth steering member 64.

[0058] The third steering member 63 and the fourth steering member 64 are located on the side of the movable part 3 near the spool assembly 2. The third steering member 63 can be fixed to the end of the first beam 11 near the spool assembly 2, and the fourth steering member 64 can be fixed to the end of the second beam 12 near the spool assembly 2. That is, the first steering member 61 and the second steering member 62 are located on the side of the frame 1 away from the spool assembly 2, and the third steering member 63 and the fourth steering member 64 are located on the side of the frame 1 near the spool assembly 2. In other words, the first steering member 61 and the second steering member 62, and the third steering member 63 and the fourth steering member 64 are respectively located on both sides of the movable part 3. The second pull cable 532 is led out from the first end 31 of the movable part 3, passes around the first steering member 61 for the first steering, passes around the third steering member 63 for the second steering, and then connects to the second end 32 of the movable part 3. The third pull cable 533 is led out from the second end 32 of the movable part 3, passes around the second steering member 62 for the first steering, passes around the fourth steering member 64 for the second steering, and then connects to the reel 52.

[0059] After the second pull wire 532 and the third pull wire 533 are turned by the first steering member 61, the second steering member 62, the third steering member 63 and the fourth steering member 64, a drive mechanism 51 drives the winding wheel 52 to rotate, and at the same time, one of the first pull wire 531 and the third pull wire 533 unfolds and the other is wound up, thereby driving the unfolding or winding of the curtain fabric 4.

[0060] Among them, the third steering component 63 and the fourth steering component 64 can be fixed pulleys, and the fixed pulleys are provided with circumferential grooves for the second pull wire 532 and the third pull wire 533 to be wound.

[0061] For example, the first steering component 61 and the third steering component 63 can be connected to the first beam 11 via brackets, and the second steering component 62 and the fourth steering component 64 can be connected to the second beam 12 via brackets.

[0062] Optionally, refer to Figure 1 and Figure 2 The sunshade device also includes a first sleeve 71, a second sleeve 72 and a third sleeve 73. The first sleeve 71 is sleeved on the first pull wire 531, the second sleeve 72 is sleeved on the part of the second pull wire 532 located between the third steering member 63 and the second end 32, and the third sleeve 73 is sleeved on the part of the third pull wire 533 located between the fourth steering member 64 and the winding wheel 52.

[0063] The first sleeve 71, the second sleeve 72, and the third sleeve 73 can be plastic tubes with a certain strength and flexibility. The first sleeve 71 is fitted onto the first pull cable 531. By changing the position or direction of the first sleeve 71, the first pull cable 531 can be positioned at a predetermined location or redirected. For example, if the first sleeve 71 is set along the contour of the frame 1, when the winding reel 52 drives the first pull cable 531 to move, the first pull cable 531 slides within the first sleeve 71 without affecting the movement of the curtain 4. By fitting the second sleeve 72 onto the portion of the second pull cable 532 located between the third steering member 63 and the second end 32, the position or direction of the second sleeve 72 can be changed, allowing the second pull cable 532 to extend along a predetermined route to the second end 32. For example, the second sleeve 72 can be positioned along the contour of the frame 1 from the first beam 11 near the winding reel. One end of the shaft assembly 2 extends to the end of the second beam 12 near the roller assembly 2, and then extends to the second end 32 of the movable part 3. When the winding wheel 52 drives the second pull cable 532 to move, the second pull cable 532 slides in the second sleeve 72 and does not affect the movement of the curtain 4. The third pull cable 533 is located between the fourth steering member 64 and the winding wheel 52 and is provided with the third sleeve 73. The third pull cable 533 can be set in a predetermined position or achieve the purpose of steering by changing the position or direction of the third sleeve 73. For example, if the third sleeve 73 is set along the outline of the frame 1, when the winding wheel 52 drives the third pull cable 533 to move, the third pull cable 533 slides in the third sleeve 73 and does not affect the movement of the curtain 4.

[0064] The installation of the first sleeve 71, the second sleeve 72, and the third sleeve 73 can improve the positional accuracy of the first pull wire 531, the second pull wire 532, and the third pull wire 533, with stronger tolerance and easier installation, and can make the movement of the first pull wire 531, the second pull wire 532, and the third pull wire 533 more stable.

[0065] Optionally, refer to Figure 2 The sunshade device also includes a fixing base 81 and two fixing tubes 82. Along the left-right direction X, the two fixing tubes 82 are respectively located at both ends of the fixing base 81. The drive mechanism 51 is located on the fixing base 81. The first pull wire 531 and the third pull wire 533 pass through the inner hole of the corresponding fixing tube 82.

[0066] The mounting bracket 81 can be fixed to the vehicle body. The first pull cable 531 extends out from the winding wheel 52 and passes through the inner hole of the fixing tube 82. The fixing tube 82 can guide and limit the first pull cable 531. The third pull cable 533 extends out from the winding wheel 52 and passes through the inner hole of the fixing tube 82. The fixing tube 82 can guide and limit the third pull cable 533.

[0067] Optionally, refer to Figure 3The inner hole of the fixed tube 82 includes a first segment 821 and a second segment 822. The first segment 821 is closer to the winding wheel 52 than the second segment 822. The inner diameter of the first segment 821 is smaller than the inner diameter of the second segment 822 to form a first stepped surface 823. The end of the first sleeve 71 near the winding wheel 52 and the end of the third sleeve 73 near the winding wheel 52 respectively abut against the corresponding first stepped surface 823.

[0068] The first segment 821 is used to guide and position the first pull wire 531 and the third pull wire 533. The first sleeve 71, which is sleeved on the first pull wire 531, abuts against the corresponding first step surface 823 at one end near the winding wheel 52 to limit the position of the first sleeve 71 and reduce its movement, thereby improving the accuracy of the first pull wire 531. The third sleeve 73, which is sleeved on the third pull wire 533, abuts against the corresponding first step surface 823 at one end near the winding wheel 52 to limit the position of the third sleeve 73 and reduce its movement, thereby improving the accuracy of the third pull wire 533.

[0069] For example, the end of the first sleeve 71 furthest from and near the first end 31 of the movable part 3 can abut against the movable part 3. Alternatively, a sleeve can be provided at the location where the first pull line 531 connects to the movable part 3, with the end face of the sleeve abutting against the end face of the first sleeve 71 to further restrict the movement of the first sleeve 71, thereby improving the accuracy of the first pull line 531. The end of the third sleeve 73 furthest from and near the fourth steering member 64 can abut against the bracket connecting the fourth steering member 64 and the second beam 12. Alternatively, a sleeve can be provided at the location where the third pull line 533 connects to the bracket connecting the fourth steering member 64 and the second beam 12, with the end face of the sleeve abutting against the end face of the third sleeve 73 to further restrict the movement of the third sleeve 73, thereby improving the accuracy of the third pull line 533. One end of the second sleeve 72 can abut against the bracket connecting the third steering component 63 and the first beam 11, or a sleeve that abuts against the second sleeve 72 is provided at the position where the fourth steering component 64 and the bracket connecting the second beam 12 are connected. The other end of the second sleeve 72 can abut against the second end 32, or a sleeve is provided at the position where the second pull line 532 is connected to the second end 32 of the movable part 3. The end face of the sleeve abuts against the end face of the second sleeve 72 to restrict the movement of the second sleeve 72, thereby improving the accuracy of the second pull line 532.

[0070] In other words, the turning of the first guy wire 531 can be achieved through the first sleeve 71, the turning of the part of the second guy wire 532 that is sleeved in the second sleeve 72 can be achieved through the second sleeve 72, and the turning of the part of the third guy wire 533 that is sleeved in the third sleeve 73 can be achieved through the third sleeve 73.

[0071] Optionally, refer to Figure 2 , Figure 4 and Figure 5Along the unfolding direction Z of the curtain 4, both the first beam 11 and the second beam 12 are provided with sliding grooves 13; the movable part 3 includes a main body 33 and two sliders 34. The main body 33 is connected to the other end of the curtain 4. The two sliders 34 are respectively located at both ends of the main body 33 and slide in cooperation with the corresponding sliding grooves 13. The other end of the first pull line 531 and one end of the second pull line 532 are connected to one of the sliders 34. The other end of the second pull line 532 and one end of the third pull line 533 are connected to the other slider 34.

[0072] The two sliders 34 and the main body 33 can be an integral structure or a plug-in structure. One end of the first pull cable 531 is connected to the winding wheel 52, and the other end is connected to the slider 34 at the first end 31. One end of the second pull cable 532 is connected to the slider 34 at the first end 31, and the other end is connected to the slider 34 at the second end 32. One end of the third pull cable 533 is connected to the slider 34 at the second end 32, and the other end is connected to the winding wheel 52. When the drive mechanism 51 drives the winding wheel 52 to rotate, the movement of the first pull cable 531, the second pull cable 532, and the third pull cable 533 can pull the slider 34 to move along the slide groove 13, thereby causing the main body 33 to drive the curtain 4 to unfold or rewind.

[0073] Optionally, refer to Figure 5 and Figure 6 The slide groove 13 includes a first slide groove 131 and a second slide groove 132, which are spaced apart along the left-right direction X. The slider 34 includes a main body 341, a first part 342 and a second part 343, both of which are connected to the main body 341. The first part 342 and the second part 343 are spaced apart along the left-right direction X. The first part 342 is slidably engaged with the first slide groove 131 and the second part 343 is slidably engaged with the second slide groove 132.

[0074] The first part 342 of the slider 34 is slidably engaged with the first groove 131, and the second part 343 is slidably engaged with the second groove 132. The first groove 131 and the second groove 132 guide the movement of the slider 34, making the movement of the slider 34 more stable.

[0075] Optionally, along the vertical direction Y, the second slide groove 132 includes a first sidewall 1321 and a second sidewall 1322 disposed opposite to each other; the lower end face of the second part 343 abuts against the first sidewall 1321, and the upper end face of the second part 343 is provided with a spring piece 344, which elastically abuts against the second sidewall 1322.

[0076] Specifically, one end of the spring piece 344 is connected to the second part 343, and the other end of the spring piece 344 extends along the unfolding direction Z of the curtain 4 and is spaced apart from the upper end face of the second part 343. The lower end face of the second part 343 abuts against the first side wall 1321. After being pressed, the other end of the spring piece 344 can move toward the upper end face of the second part 343 to ensure that the upper end face of the spring piece 344 abuts against the second side wall 1322, thereby limiting the displacement of the slider 34 in the vertical direction Y. The first part 342 is accommodated in the first slide groove 131 to limit the displacement of the slider 34 in the horizontal direction X, thereby making the movement of the slider 34 more stable.

[0077] Optionally, refer to Figure 7 The roller assembly 2 includes a spindle 21, a sleeve 23, and a torsion spring 22. Along the left-right direction X, both ends of the spindle 21 are connected to the first beam 11 and the second beam 12, respectively. The torsion spring 22 is sleeved on the spindle 21, and the sleeve 23 is sleeved on the spindle 21. The torsion spring 22 is located between the spindle 21 and the sleeve 23, with one end connected to the spindle 21 and the other end connected to the sleeve 23. When the movable part 3 drives the curtain 4 to unfold, the torsion spring 22 stores energy; when the curtain 4 is rolled up, the torsion spring 22 drives the sleeve to rotate, and the rotation of the sleeve drives the curtain 4 to roll up.

[0078] Secondly, embodiments of this application provide a vehicle including the sunshade device described in any of the above embodiments. The vehicle in this embodiment has the beneficial effects of the sunshade device described in any of the above embodiments.

[0079] In this application, the third pull wire 533 extends from the winding wheel 52, passes around the fourth steering member 64 and the second steering member 62, and connects to the slider 34 of the second end 32. One end of the second pull wire 532 is connected to the slider 34 of the second end 32, extends along the second beam 12 toward the winding assembly, turns toward the first beam 11, passes around the third steering member 63 and the first steering member 61, and connects to the slider 34 of the first end 31. One end of the first pull wire 531 extends from the winding wheel 52 and connects to the slider 34 of the first end 31.

[0080] When the drive mechanism 51 rotates forward, the first pull cable 531 unfolds, the winding wheel 52 winds up the third pull cable 533, the third pull cable 533 pulls the slider 34 of the second end 32 to slide away from the winding assembly 2, the slider 34 of the second end 32 pulls the second pull cable 532, the second pull cable 532 pulls the slider 34 of the first end 31 to slide away from the winding assembly 2, so that the curtain 4 unfolds. During the unfolding process of the curtain 4, the curtain 4 drives the sleeve 23 to rotate, and at the same time the torsion spring 22 stores energy. When the drive mechanism 51 reverses, the third pull cable 533 unfolds, the winding wheel 52 winds up the first pull cable 531, the first pull cable 531 pulls the slider 34 at the first end 31 to slide towards the winding assembly 2, the slider 34 at the first end 31 pulls the second pull cable 532, the second pull cable 532 pulls the slider 34 at the second end 32 to slide towards the winding assembly 2, at the same time, the torsion spring 22 drives the sleeve 23 to rotate, so that the curtain 4 is wound into the winding assembly 2. The whole movement process is smooth and has low noise.
