Description

Technical Field

[0001] This application relates to the field of sunshade tool technology, and in particular to a sunshade curtain drive mechanism, a sunshade curtain assembly, a window assembly and equipment. Background Technology

[0002] In related technologies, the curtain fabric in a direct-drive sunshade is wound around a pull rod and a roller at the front and rear, respectively. A winding wheel is set at one end of the roller, and two reversing fixed pulleys are set on both sides of the front end of the sunroof frame. Slider blocks are connected to both ends of the pull rod. Two curtain cords are wound synchronously on the winding wheel. The two curtain cords are released towards the pull rod and wound around the reversing fixed pulleys. One curtain cord is connected to the slider at one end of the pull rod from the reversing fixed pulley at the front end of the sunroof frame at one end of the roller, and the other curtain cord is connected to the slider at the other end of the pull rod from the reversing fixed pulley at the front end of the sunroof frame at the other end of the roller. Two curtain cords are released from a single-sided winding wheel. One cord is reversed by a reversing fixed pulley and a reversing movable pulley on this side and pulls this end of the pull rod. The other cord is wound around a reversing fixed pulley on this side to the reversing fixed pulley on the other side of the sunroof frame and then pulled by the reversing movable pulley at the other end of the pull rod. The winding power of the curtain cords at both ends of the pull rod is controlled by the same winding wheel, resulting in high stability and synchronization.

[0003] However, this type of sunshade structure requires a direct drive motor to drive the winding wheel to tighten the curtain cords when closing the sunshade. After prolonged use, the two curtain cords become longer and cannot be adjusted, which can easily lead to operational deviations during the operation of the sunshade. Utility Model Content

[0087] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0088] As described in the background section, in related technologies, the two curtain cords of a sunshade structure tend to lengthen after a period of use and cannot be adjusted, leading to operational deviations during operation. Therefore, this application provides a novel sunshade drive mechanism and sunshade assembly that solves the technical problem of operational deviations that easily occur in sunshade structures after a period of use in related technologies. The sunshade drive mechanism and sunshade assembly of this application will be described and explained in detail below with reference to the accompanying drawings.

[0089] See Figures 1 to 3 As shown, according to an embodiment of this application, a sunshade assembly is provided, which includes a sunshade drive mechanism 100 and a curtain fabric 23. The sunshade drive mechanism 100 includes a mounting frame 10 and a roller blind mechanism 20.

[0090] Combination Figures 1 to 4As shown, the mounting frame 10 has a first side 111 and a second side 112 opposite to the first side 111. The roller blind mechanism 20 includes a roller blind shaft 21, a support beam 22, a first pull cable 24, a second pull cable 25, a first elastic element 26, a second elastic element 27, and a reversing assembly 28. The roller blind shaft 21 is rotatably disposed on the first side 111 about its own axis, and the support beam 22 is parallel to the roller blind shaft 21 and can reciprocate between the first side 111 and the second side 112. In actual assembly, the curtain fabric 23 is connected between the support beam 22 and the roller blind shaft 21. The reversing assembly 28 is disposed on the mounting frame 10 and located on the second side 112. The first end of the first pull cable 24 and the first end of the second pull cable 25 are both connected to the roller blind shaft 21. The second end of the first pull cable 24 passes around the reversing assembly 28 and is connected to the support beam 22 through the first elastic element 26. The second end of the second pull cable 25 passes around the reversing assembly 28 and is connected to the support beam 22 through the second elastic element 27.

[0091] In actual use, the sunshade drive mechanism 100 of this embodiment is installed on a predetermined window, and the mounting frame 10 has a window 11. If the sunshade function needs to be activated, simply rotate the roller blind shaft 21 around its own axis, causing the first pull cable 24 and the second pull cable 25 connected to the roller blind shaft 21 to wind and roll up onto the roller blind shaft 21. At this time, the first pull cable 24 and the second pull cable 25 bypass the reversing assembly 28 and pull the support beam 22 toward the second side 112 closer to the window 11. At the same time, the roller blind shaft 21 unrolls the curtain 23, and as the support beam 22 moves toward the second side 112, it can pull the curtain 23 to cover the window 11. If the sunshade function does not need to be activated, simply rotate the roller blind shaft 21 around its own axis, causing the first pull cable 24 and the second pull cable 25 connected to the roller blind shaft 21 to release from the roller blind shaft 21. During this process, the roller shutter shaft 21 synchronously winds the curtain fabric 23, driving the support beam 22 to move towards the first side 111. This allows the curtain fabric 23 to avoid the opening window 11 on the mounting frame 10, and simultaneously straightens the first pull cable 24 and the second pull cable 25, preventing redundant accumulation of the first pull cable 24 and the second pull cable 25 from getting tangled with other external structures.

[0092] In this application, since the second end of the first cable 24 is connected to the support beam 22 through the first elastic element 26, and the second end of the second cable 25 is connected to the support beam 22 through the second elastic element 27, when the first cable 24 or the second cable 25 becomes longer after a period of use, the first elastic element 26 or the second elastic element 27 can absorb the deformation of the first cable 24 and the second cable 25 by means of its own elasticity, thereby adaptively adjusting the tension of the first cable 24 and the second cable 25, which can effectively improve the running deviation of the first cable 24 and the second cable 25 after a period of use, and improve the stability and reliability of the sunshade drive mechanism 100.

[0093] Furthermore, in this application, the second end of the first cable 24 is connected to the support beam 22 via the first elastic element 26, and the second end of the second cable 25 is connected to the support beam 22 via the second elastic element 27. The first elastic element 26 and the second elastic element 27 are independent of each other, and the tension of the first cable 24 and the second cable 25 can be adjusted separately to avoid mutual interference between the tensions of the first cable 24 and the second cable 25. This facilitates the separate adjustment of the operating error of the first cable 24 and the second cable 25, ensures the consistency of the operation of the first cable 24 and the second cable 25, and facilitates subsequent maintenance of the sunshade drive mechanism 100.

[0094] For example, in this embodiment, at least one of the first elastic element 26 and the second elastic element 27 includes a tension spring, which has a simple structure and a long service life. Of course, in other embodiments of this application, the first elastic element 26 and the second elastic element 27 can also be structures such as elastic rubber strips. Any other variation within the concept of this application is within the protection scope of this application.

[0095] See Figure 1 As shown, in some embodiments, the mounting frame 10 can be a square frame, a rectangular frame, a circular frame, a trapezoidal frame, or other irregularly shaped frames. Figure 1 The image shows the case where the mounting frame 10 is a rectangular frame. The mounting frame 10 can be formed by connecting multiple crossbeams or can be integrally molded; this application does not impose any specific limitations.

[0096] In some embodiments, the support beam 22 can be a hollow beam. In actual installation, the first elastic element 26 and the second elastic element 27 are installed inside the hollow beam. The first cable 24 and the second cable 25 extend at least partially into the hollow beam and are connected to the first elastic element 26 and the second elastic element 27 respectively. The structure is more stable, the appearance is intact, and it is not easily affected by external structures.

[0097] In addition, this application uses two cables, namely the first cable 24 and the second cable 25, which are respectively connected to the support beam 22, so that the support beam 22 can be moved smoothly, which can further improve the structural stability of the sunshade drive mechanism 100.

[0098] In some embodiments, at least one of the first cable 24 and the second cable 25 comprises a galvanized steel cable and a stainless steel cable. That is, the first cable 24 can be either a galvanized steel cable or a stainless steel cable, and the second cable 25 can also be either a galvanized steel cable or a stainless steel cable. Using galvanized steel cables and stainless steel cables for the first cable 24 and the second cable 25 results in high structural strength, excellent moisture and rust resistance, and a long service life. Of course, in other embodiments of this application, the first cable 24 and the second cable 25 can also be plastic ropes, nylon ropes, etc. Any other variations within the concept of this application are within the scope of protection of this application.

[0099] In some embodiments, a sliding assembly 30 is provided between the support beam 22 and the mounting frame 10, and the support beam 22 slides along the sliding assembly 30 to reciprocate between a first side 111 and a second side 112. By providing the sliding assembly 30 between the support beam 22 and the mounting frame 10 and allowing the support beam 22 to slide along the sliding assembly 30, this application can improve the smoothness of movement of the support beam 22.

[0100] Optionally, the sliding assembly 30 includes a first guide rail 31, a second guide rail 32, a first slider 33, and a second slider 34. The first guide rail 31 and the second guide rail 32 are both mounted on the mounting frame 10 and extend along a direction from the first side 111 to the second side 112. The first guide rail 31 and the second guide rail 32 are located on the third side 113 and the fourth side 114 of the mounting frame 10, respectively. The third side 113 is located between the corresponding first ends of the first side 111 and the second side 112, and the fourth side 114 is located between the corresponding second ends of the first side 111 and the second side 112. The first slider 33 is disposed at the first end of the support beam 22 and slidably disposed on the first guide rail 31. The second slider 34 is disposed at the second end of the support beam 22 and slidably disposed on the second guide rail 32. Thus, when the roller shutter shaft 21 rotates around its own axis and releases and winds the first cable 24, the second cable 25 and the curtain 23, it can pull the first slider 33 and the second slider 34 at both ends of the support beam 22 to slide along the first guide rail 31 and the second guide rail 32 respectively. The structure is simple and has high stability.

[0101] Combination Figures 1 to 4 As shown, a first guide portion 331 is provided on the first slider 33, and the first cable 24 is at least partially disposed on the first guide portion 331. By providing the first guide portion 331 on the first cable 24, this application facilitates the guidance of the first cable 24 and improves the neatness of the cable routing.

[0102] For example, in some embodiments, the first guide portion 331 includes a first arc-shaped guide groove 3311. The first end of the first arc-shaped guide groove 3311 extends to the side of the first slider 33 near the reversing assembly 28, and the second end extends to the side of the first slider 33 near the second end of the support beam 22. Thus, after reversing via the reversing assembly 28, the first cable 24 can enter the first arc-shaped guide groove 3311 from the side of the first slider 33 near the reversing assembly 28 and exit from the side of the first slider 33 near the second end of the support beam 22, facilitating connection with the first elastic member 26 disposed on the support beam 22. Simultaneously, the first arc-shaped guide groove 3311 improves the smoothness of movement of the first cable 24, preventing interference or wear between the first slider 33 and the first cable 24. Of course, in other embodiments of this application, the first guide portion 331 can also be an arc-shaped guide hole; any other variations within the scope of this application are within the protection scope of this application.

[0103] Furthermore, the first slider 33 is provided with a first limiting part 332, which is disposed on the outer side of the first guide part 331 to at least limit the first cable 24 within the first guide part 331, i.e., the first arc-shaped guide groove 3311, thereby further improving the installation stability of the first cable 24. It is understood that in this embodiment, the outer side of the first guide part 331 refers to the outer periphery of the first guide part 331 in its extending direction. Specifically, it can be the outer side of the end of the first arc-shaped guide groove 3311, or any position on the outer edge of the first arc-shaped guide groove 3311, as long as it can limit the first cable 24 within the first guide part 331.

[0104] In some embodiments, the first limiting portion 332 includes at least one first limiting block 3321. Exemplarily, the first limiting block 3321 can be one, two, three, or more than four. When multiple first limiting blocks 3321 are provided, they are spaced apart along the length direction of the first guide portion 331, i.e., the length direction of the first arc-shaped guide groove 3311. During actual installation, the first limiting block 3321 is located outside the first arc-shaped guide groove 3311 and is at least partially suspended above the top of the first guide portion 331, thus confining the first cable 24 within the first arc-shaped guide groove 3311.

[0105] Furthermore, a second guide portion 341 is provided on the second slider 34, and the second cable 25 is at least partially disposed on the second guide portion 341. By providing the second guide portion 341 on the second cable 25, this application facilitates the guidance of the second cable 25 and improves the neatness of the cable routing.

[0106] For example, in some embodiments, the second guide portion 341 includes a second arc-shaped guide groove 3411. The first end of the second arc-shaped guide groove 3411 extends to the side of the second slider 34 near the reversing assembly 28, and the second end extends to the side of the second slider 34 near the first end of the support beam 22. Thus, after being reversed by the reversing assembly 28, the second cable 25 can enter the second arc-shaped guide groove 3411 from the side of the second slider 34 near the reversing assembly 28 and exit from the side of the first slider 33 near the first end of the support beam 22, facilitating connection with the second elastic member 27 disposed on the support beam 22. Simultaneously, the provision of the second arc-shaped guide groove 3411 can improve the smoothness of movement of the second cable 25, preventing interference or wear between the second slider 34 and the second cable 25. Of course, in other embodiments of this application, the second guide portion 341 can also be an arc-shaped guide hole; any other variations within the concept of this application are within the scope of protection of this application.

[0107] Furthermore, the second slider 34 is provided with a second limiting part 342, which is disposed on the outer side of the second guide part 341 to at least limit the second cable 25 within the second limiting part 342, i.e., the second arc-shaped guide groove 3411, thereby further improving the installation stability of the second cable 25. It is understood that in this embodiment, the outer side of the second guide part 341 refers to the outer periphery of the second guide part 341 in its extending direction. Specifically, it can be the outer side of the end of the second arc-shaped guide groove 3411, or any position on the outer edge of the second arc-shaped guide groove 3411, as long as it can limit the first cable 24 within the second arc-shaped guide groove 3411.

[0108] In some embodiments, the second limiting portion 342 includes at least one second limiting block 3421. Exemplarily, the second limiting portion 342 can be one, two, three, or more than four blocks. When multiple second limiting portions 342 are provided, they are spaced apart along the length direction of the second guide portion 341, i.e., the length direction of the second arc-shaped guide groove 3411. During actual installation, the second limiting portion 342 is located outside the second arc-shaped guide groove 3411 and is at least partially suspended above the top of the second limiting portion 342, thus confining the second cable 25 within the second arc-shaped guide groove 3411.

[0109] Furthermore, the sunshade drive mechanism 100 also includes a first fixed base 40, which is fixed to the support beam 22. A first elastic element 26 is connected between the first fixed base 40 and the first pull cable 24. By providing the first fixed base 40, the assembly of the first elastic element 26 is facilitated. Optionally, the sunshade drive mechanism 100 also includes a second fixed base 50, which is fixed to the support beam 22. A second elastic element 27 is connected between the second fixed base 50 and the second pull cable 25, facilitating the assembly of the second elastic element 27.

[0110] Optionally, the first fixing seat 40 and the second fixing seat 50 can be structures such as fixing blocks. The first fixing seat 40 and the second fixing seat 50 are set on the support beam 22 by at least one of the following methods: snap-fit, screw-fit, and welding. The structure is simple and easy to assemble.

[0111] In some embodiments, the first elastic element 26 is connected to the first fixed base 40 by at least one of snap-fit, screw-fit, and welding, which is simple in structure and easy to implement.

[0112] In some embodiments, the second elastic element 27 is connected to the second fixed base 50 by at least one of snap-fit, screw-fit, and welding, which is simple in structure and easy to implement.

[0113] Furthermore, in this application, the first end of the first cable 24 and the first end of the second cable 25 are both connected to the first end of the roller blind shaft 21. Compared to the method of separately setting the first cable 24 and the second cable 25 on the roller blind shaft 21, in this application, by connecting the first end of the first cable 24 and the first end of the second cable 25 to the first end of the roller blind shaft 21, the operating error caused by coaxiality error during the winding process of the first cable 24 and the second cable 25 can be effectively reduced, and the operating synchronization of the first cable 24 and the second cable 25 can be improved.

[0114] In some embodiments, the second side 112 has a mounting end 1121 opposite to the first end of the roller blind shaft 21, that is, the mounting end 1121 and the first end of the roller blind shaft 21 are located on the same side of the mounting frame 10, and the reversing assembly 28 includes a first reversing wheel 281, a second reversing wheel 282 and a third reversing wheel 283, wherein the first reversing wheel 281 is rotatable about its own axis and is mounted on the mounting end 1121, and the axis of the first reversing wheel 281 is perpendicular to or inclined to the plane where the mounting frame 10 is located; the second reversing wheel 282 is rotatable about its own axis and is mounted on the mounting end 1121, and the axis of the second reversing wheel 282 is perpendicular to or inclined to the plane where the mounting frame 10 is located; the third reversing wheel 283 is rotatable about its own axis and is disposed on the other end of the second side 112 opposite to the mounting end 1121, and the axis of the third reversing wheel 283 is perpendicular to or inclined to the plane where the mounting frame 10 is located. It is understood that the plane where the mounting frame 10 is located in this embodiment is the same plane where the positioning window 11 is located. The second cable 25 is wound around the first reversing wheel 281 and the third reversing wheel 283, guiding the second cable 25 to change direction and connecting it to the support beam 22 from the second slider 34; the first cable 24 is wound around the second reversing wheel 282, guided to change direction via the second reversing wheel 282, and connected to the support beam 22 from the first slider 33. In this way, the first cable 24 and the second cable 25 can respectively pull the support beam 22 from both ends, further improving the movement stability of the support beam 22.

[0115] In other words, the reversing component 28 of this application can guide the first cable 24 and the second cable 25 along the first side 111 of the mounting frame 10 to the second side 112 and to the two ends of the support beam 22 respectively, thereby smoothly pulling the support beam 22 back and forth between the first side 111 and the second side 112.

[0116] Meanwhile, in this embodiment, by making the axes of the first reversing wheel 281, the second reversing wheel 282, and the third reversing wheel 283 perpendicular or inclined to the plane where the window 11 is located, it is convenient to reverse the direction of the first cable 24 and the second cable 25, ensuring that the first cable 24 and the second cable 25 pull the support beam 22 from the first side 111 of the window 11 to the second side 112.

[0117] like Figure 3 As shown, in some embodiments, the first reversing wheel 281 and the second reversing wheel 282 are coaxially arranged. This arrangement can improve the structural compactness of the entire sunshade drive mechanism 100 and reduce the production and processing cost of the sunshade drive mechanism 100 of this application to a certain extent.

[0118] like Figure 5As shown, in some embodiments, the roller shutter mechanism 20 further includes a guide component 29, which is disposed in the mounting frame 10 and located between the first side 111 and the second side 112 of the window 11. The first pull cable 24 and the second pull cable 25 are both guided to the reversing component 28 through the guide component 29, which can further improve the routing regularity of the first pull cable 24 and the second pull cable 25.

[0119] Specifically, the guide assembly 29 includes a first guide wheel 291 and a second guide wheel 292. The axis of the first guide wheel 291 is parallel to the axis of the roller blind shaft 21. The first guide wheel 291 is rotatable around its own axis and is mounted on the mounting frame 10. The first pull cable 24 is attached to the first guide wheel 291. The axis of the second guide wheel 292 is parallel to the axis of the roller blind shaft 21. The second guide wheel 292 is rotatable around its own axis and is mounted on the mounting frame 10. The second pull cable 25 is attached to the second guide wheel 292. Through the action of the first guide wheel 291 and the second guide wheel 292, the first pull cable 24 and the second pull cable 25 can be guided in a direction closer to the reversing assembly 28, respectively.

[0120] Furthermore, the guide assembly 29 also includes a connecting shaft 293, which is parallel to the roller blind shaft 21 and fixed to the mounting frame 10. The first guide wheel 291 and the second guide wheel 292 are both sleeved on the connecting shaft 293 and can move along the axial direction of the connecting shaft 293. This arrangement ensures that when the first pull cable 24 and the second pull cable 25 are taut under tension, the first guide wheel 291 and the second guide wheel 292 can move axially along the connecting shaft 293, preventing interference and wear between the first pull cable 24 and the first guide wheel 291, or interference and wear between the second pull cable 25 and the second guide wheel 292. This improves the service life and flexibility of the entire sunshade drive mechanism 100.

[0121] Combination Figures 5 to 10 As shown, the sunshade drive mechanism 100 of this application also includes a winding structure 60, which is fixedly connected to the first end of the roller blind shaft 21. The first end of the first pull cable 24 and the first end of the second pull cable 25 are both connected to the winding structure 60. By winding the first end of the first pull cable 24 and the first end of the second pull cable 25 around the winding structure 60, the synchronicity of the operation of the first pull cable 24 and the second pull cable 25 can be guaranteed, and the coaxiality error and relative error of the first pull cable 24 and the second pull cable 25 during operation can be reduced.

[0122] In some embodiments, the winding structure 60 includes a first winding wheel 61 and a second winding wheel 62. The first winding wheel 61 is coaxially arranged with the roller blind shaft 21, and a first spiral winding groove 611 is provided on the outer peripheral surface of the first winding wheel 61. The first end of the first pull cable 24 is fixed to the first spiral winding groove 611, specifically fixed to the side of the first spiral winding groove 611 away from the second end of the roller blind shaft 21. The second winding wheel 62 is connected to the side of the first winding wheel 61 near the second end of the roller blind shaft 21, and the second winding wheel 62 is coaxially arranged with the roller blind shaft 21. The outer peripheral surface of the second winding wheel 62 is provided with a second spiral winding groove 621, and the first end of the second pull cable 25 is fixed to the second spiral winding groove 621, specifically fixed to the side of the second spiral winding groove 621 near the second end of the roller blind shaft 21. When the roller blind shaft 21 rotates in the first direction, the first winding wheel 61 and the second winding wheel 62 simultaneously wind the first pull cable 24 and the second pull cable 25. This causes the first pull cable 24 and the second pull cable 25 to pull the support beam 22 towards the second side 112 closer to the window 11, facilitating the unfolding of the curtain 23 to cover the window 11 for sun shading. When the roller blind shaft 21 rotates in the second direction opposite to the first direction, the first winding wheel 61 and the second winding wheel 62 simultaneously release the first pull cable 24 and the second pull cable 25, allowing the curtain 23 to be wound around the roller blind shaft 21 and simultaneously pulling the support beam 22 towards the first side 111 closer to the window 11 to open the window 11. It is understood that the first direction in this application can be clockwise or counterclockwise. When the first direction is clockwise, the second direction is counterclockwise, and when the first direction is clockwise, the second direction is clockwise. The specific direction can be set according to the rotation direction of the first spiral winding groove 611 and the second spiral winding groove 621. This application does not make specific limitations.

[0123] Furthermore, both the first winding wheel 61 and the second winding wheel 62 are conical winding wheels, and the first winding wheel 61 and the second winding wheel 62 are symmetrically arranged about the connecting surface 80 of the first winding wheel 61 and the second winding wheel 62. In this way, when the roller blind shaft 21 rotates, it can drive the first pull cable 24 and the second pull cable 25 to wind and release synchronously, which can improve the synchronicity of the operation of the support beam 22.

[0124] For example, the cross-section of the first winding wheel 61 gradually increases from the first end to the second end of the roller blind shaft 21; the cross-section of the second winding wheel 62 gradually decreases from the first end to the second end of the roller blind shaft 21. That is to say, the winding structure 60 is a structure that is thick in the middle and thin at both ends, which facilitates the steady speed increase or deceleration release and winding of the first pull cable 24 and the second pull cable 25. The structure is simple and easy to use.

[0125] It is understood that the cross-section of the first winding wheel 61 in this application refers to the cross-section obtained by cutting the first winding wheel 61 along a direction perpendicular to its axis; the cross-section of the second winding wheel 62 refers to the cross-section obtained by cutting the second winding wheel 62 along a direction perpendicular to its axis. The first spiral winding groove 611 and the second spiral winding groove 621 are coaxially arranged with the roller blind shaft 21.

[0126] In some embodiments, a positioning protrusion 612 is provided on one of the sides of the first winding wheel 61 near the second winding wheel 62 and the side of the second winding wheel 62 near the first winding wheel 61, and a positioning groove 622 adapted to the positioning protrusion 612 is provided on the other side. That is, when the positioning protrusion 612 is provided on the side of the first winding wheel 61 near the second winding wheel 62, the positioning groove 622 is provided on the side of the second winding wheel 62 near the first winding wheel 61; when the positioning groove 622 is provided on the side of the first winding wheel 61 near the second winding wheel 62, the positioning protrusion 612 is provided on the side of the second winding wheel 62 near the first winding wheel 61. Through the cooperation of the positioning protrusion 612 and the positioning groove 622, it is convenient to install and position the first winding wheel 61 and the second winding wheel 62, which can improve the coaxiality and assembly speed when the two are connected.

[0127] In some embodiments, the first winding wheel 61 and the second winding wheel 62 are connected by at least one of screwing, bonding, snapping or welding, which is simple in structure and easy to implement. The accompanying drawings of this application show the case in which the first winding wheel 61 and the second winding wheel 62 are connected by screws and bolts.

[0128] In some embodiments, the filament winding structure 60 and the roller blind shaft 21 are connected by at least one of screwing, bonding, snap-fitting or welding, which is simple in structure and easy to implement.

[0129] Combination Figures 1 to 2 ,as well as Figure 11 As shown, the sunshade drive mechanism 100 of this application also includes a drive assembly 70, which is connected to the roller blind shaft 21 to drive the roller blind shaft 21 to rotate around its own axis, facilitating automatic control. Exemplarily, the drive assembly 70 and the roller blind shaft 21, as well as the roller blind shaft 21 and the mounting frame 10, are connected by at least one of the following methods: screw connection, welding, and snap-fit ​​connection.

[0130] In some embodiments, the drive assembly 70 includes a motor 71 and an adapter sleeve 72. The adapter sleeve 72 is connected between the motor 71 and the second end of the roller blind shaft 21. The rotation of the motor 71 drives the adapter sleeve 72 and the roller blind shaft 21 to rotate. This structure is simple and easy to implement. Meanwhile, by placing the winding structure 60 and the motor 71 at opposite ends of the roller blind shaft 21, the stress on both ends of the roller blind shaft 21 can be balanced, which can improve the structural strength and service life of the sunshade drive mechanism 100 of this application to a certain extent. The adapter sleeve 72 and the roller blind shaft 21 are engaged by a snap-fit ​​mechanism, which is simple in structure and easy to assemble and disassemble.

Therefore, this window assembly includes all the technical effects of the aforementioned sunshade drive mechanism 100 and sunshade assembly.
