Description

Technical Field

[0001] This utility model relates to the field of skylight curtain manufacturing technology, specifically to an electric day and night skylight curtain. Background Technology

[0002] Skylight blinds are a type of blind that are typically laid flat or tilted on a glass ceiling. They provide multiple functions, including sunshade, heat insulation, and light control, by adjusting the opening and closing of the blinds manually or electrically.

[0003] Existing electric skylight blinds include a motor, a winding device, and a traction line. One end of the traction line is fixed to the winding device, and the other end is set through the curtain in the opening and closing direction. The winding device is connected to the power output end of the motor through a rotating shaft. The motor drives the winding device to rotate and wind up and unwind the traction line, thereby realizing the opening and closing action of the curtain.

[0004] The disadvantage of the above-mentioned transmission method using a winding reel is that during the winding process, the winding reel is prone to uneven winding and knotting, which can lead to unstable opening and closing of the curtain or even jamming.

[0005] The disadvantage of the above-mentioned transmission method using a cable reel is that the cable reel, shaft, and motor are coaxially arranged, the shaft is directly connected to the motor, and both the motor and shaft are installed on the frame structure of the skylight curtain. When the motor needs to be disassembled, the shaft must also be disassembled. Specifically, the connecting parts between the motor and the frame structure (such as screws) need to be removed, the connecting parts between the shaft and the frame structure (such as bearings) need to be removed, and then the shaft needs to be removed from the motor (the coupling needs to be removed). The motor installation process is performed in reverse, making the motor disassembly and assembly process quite cumbersome. Utility Model Content

The driving wheels of the first pulley assembly and the second pulley assembly are both mounted on the upper end cap, and the driven wheels of the first pulley assembly and the second pulley assembly are both mounted on the lower end cap.

[0016] As a further improvement of this utility model, the upper rail includes a detachable cover plate.

[0017] As a further improvement of this utility model, the first motor, the second motor, the power supply module, and the electronic control module are arranged in a straight line inside the upper rail.

[0035] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0036] Please see Figures 1 to 10 An electric day and night skylight blind includes a frame, a day curtain, a night curtain, a first motor 1, and a second motor 2. The frame includes an upper rail 31, a lower rail 32, and a side rail 33. The day curtain includes a first fabric 41 and a first sliding rail 42. The night curtain includes a second fabric 51 and a second sliding rail 52. The electric day and night skylight blind also includes a first transmission mechanism and a second transmission mechanism.

[0037] The main difference between the first fabric 41 and the second fabric 51 in the day curtain and night curtain lies in their light transmittance. The upper edge of the first fabric 41 is fixedly connected to the upper rail 31, and the lower edge of the first fabric 41 is fixedly connected to the first sliding rail 42, moving with the first sliding rail 42. The lower edge of the second fabric 51 is fixedly connected to the lower rail 32, and the upper edge of the second fabric 51 is fixedly connected to the second sliding rail 52, moving with the second sliding rail 52.

[0038] The first transmission mechanism is used to drive the opening and closing of the day curtain between the first motor 1 and the first moving rail 42. The second transmission mechanism is used to drive the opening and closing of the night curtain between the second motor 2 and the second moving rail 52. Compared with the conventional transmission method that uses a reel to wind the traction line, the transmission method using gear pairs, shafts, pulley assemblies, and pulleys has the advantage of stable power transmission.

[0039] The first transmission mechanism includes a first rotating shaft 61, a first pulley assembly 62, a first gear pair 63, and a first trolley 64. The first pulley assembly 62 is provided on both sides of the frame. The ends of the first rotating shaft 61 are respectively connected to the two sets of first pulley assemblies 62. The first rotating shaft 61 is connected to the first motor 1 through the first gear pair 63. The first trolley 64 is fixedly connected to the belt of the first pulley assembly 62. The first trolley 64 extends into the end of the first transfer rail 42.

[0040] When the sunshade needs to be opened and closed, the first motor 1 drives the first rotating shaft 61 to rotate through the first gear pair 63. The first rotating shaft 61 transmits the power of the first motor 1 to the drive wheel of the first pulley assembly 62 on both sides (the drive wheel is preferably a gear to ensure friction with the belt), thereby driving the first pulley assembly 62 to run. Each side of the first pulley assembly 62 is connected to a first trolley 64. The first trolley 64 is generally L-shaped. One side of the first trolley 64 is fixedly connected to the belt so as to move with the belt, and the other side extends into the end of the first moving rail 42 so as to drive the first moving rail 42 to move in the opening and closing direction of the sunshade.

[0041] The second transmission mechanism includes a second rotating shaft 71, a second pulley assembly 72, a second gear pair 73, and a second trolley 74. The second pulley assembly 72 is provided on both sides of the frame. The ends of the second rotating shaft 71 are respectively connected to the two sets of second pulley assemblies 72. The second rotating shaft 71 is connected to the second motor 2 through the second gear pair 73. The second trolley 74 is fixedly connected to the belt of the second pulley assembly 72. The second trolley 74 extends into the end of the second transfer rail 52.

[0042] When the night curtain needs to be opened and closed, the second motor 2 drives the second shaft 71 to rotate through the second gear pair 73. The second shaft 71 transmits the power of the second motor 2 to the drive wheel of the second pulley assembly 72 on both sides (the drive wheel is preferably a gear to ensure friction with the belt), thereby driving the second pulley assembly 72 to run. Each side of the second pulley assembly 72 is connected to a second trolley 74. The second trolley 74 is generally L-shaped. One side of the second trolley 74 is fixedly connected to the belt so as to move with the belt, and the other side extends into the end of the second guide rail 52 so as to drive the second guide rail 52 to move in the opening and closing direction of the night curtain.

[0043] The upper rail 31 is provided with a gearbox 8 and a first mounting base 9. The first motor 1 and the second motor 2 are connected to the upper rail 31 through the gearbox 8 and the first mounting base 9. The gearbox 8 and the first mounting base 9 are connected to the upper rail 31 through a quick-release structure.

[0044] In this embodiment, there are two first mounting seats 9, located on opposite sides of the gearbox 8. The power output ends of the first and second motors face the gearbox 8 to facilitate transmission connection with the first and second gear pairs. The gearbox 8 and the first mounting seats 9 are respectively provided with limiting grooves that mate with the end housings of the first and second motors. The end housings of the first and second motors are inserted into the limiting grooves, allowing the first and second motors to be installed inside the upper rail 31. The gearbox 8 and the first mounting seats 9 are connected to the upper rail 31 via a quick-release structure. In practice, when the first and second motors and the first and second gear pairs use a quick-release transmission connection structure (for example, a hexagonal shaft is coaxially mounted on the driving wheel of the first and second gear pairs, and an inner hexagonal bushing is mounted on the power output shaft of the first and second motors to engage with the hexagonal shaft), disassembling and assembling the first and second motors only requires removing the first mounting seat 9 from the upper rail 31.

[0045] Furthermore, the upper rail 31 is provided with an electronic control module 10, a power supply module 11, and a second mounting base 12. The electronic control module 10 and the power supply module 11 are connected to the upper rail 31 through the first mounting base 9 and the second mounting base 12, and the second mounting base 12 is connected to the upper rail 31 through a quick-release structure.

[0046] The power module 11 is connected to external AC power and supplies power to the first and second motors after voltage conversion. The electronic control module 10 is used to control the operation of the first and second motors, thereby controlling the opening and closing of the day curtain and night curtain. The human-machine interaction mode of the electronic control module 10 can include button control, remote control, voice control, etc.

[0047] There are two second mounting bases 12, which are located outside the two first mounting bases 9 respectively. The second mounting bases 12 and the first mounting bases 9 are respectively provided with limiting grooves that cooperate with the housings at both ends of the electronic control module 10 and the power module 11. The two ends of the electronic control module 10 and the power module 11 are inserted into the limiting grooves, so that the electronic control module 10 and the power module 11 are installed inside the upper rail 31.

[0048] Furthermore, the quick-release structure includes a gearbox body 8, a first mounting base 9, a boss 13 on the upper and lower end faces of the second mounting base 12, and a positioning port 14 on the upper rail 31 that mates with the boss 13.

[0049] It should be noted that the upper rail 31 is made of aluminum alloy and has a certain degree of elasticity. Positioning openings 14 (cutouts) matching the size of the boss 13 are provided on the upper and lower sides of the upper rail 31. When installing the gearbox body 8, the first mounting base 9, and the second mounting base 12, simply align the gearbox body 8, the first mounting base 9, and the second mounting base 12 with the corresponding positioning openings 14 and press them down, causing the boss 13 to engage with the positioning openings 14. For disassembly, simply pull the gearbox body 8, the first mounting base 9, and the second mounting base 12 to disengage the boss 13 from the positioning openings 14.

[0050] Furthermore, the first gear pair 63 and the second gear pair 73 are located inside the gearbox 8. In addition to serving as the mounting carrier for the first and second gear pairs, the gearbox 8, as described above, also functions to cooperate with the first mounting base 9 to fix the first and second motors.

[0051] Furthermore, both the first transmission mechanism and the second transmission mechanism include a first transmission box 15 and a second transmission box 16. The first transmission box 15 is located at the corner of the upper rail 31 and the side rail 33, and the second transmission box 16 is located at the corner of the lower rail 32 and the side rail 33. The first transmission box 15 is provided with an upper end cap 151, and the second transmission box 16 is provided with a lower end cap 161. The driving wheels of the first pulley assembly 62 and the second pulley assembly 72 are both mounted on the upper end cap 151, and the driven wheels of the first pulley assembly 62 and the second pulley assembly 72 are both mounted on the lower end cap 161.

[0052] It should be noted that in the prior art, the upper end cap 151 is disposed at both ends of the upper rail 31, serving to seal the ends of the upper rail 31, and the lower end cap 161 is disposed at both ends of the lower rail 32, serving to seal the ends of the lower rail 32. In this utility model, the upper end cap 151 and the lower end cap 161 also serve as mounting carriers for the first and second pulley assemblies.

[0053] Furthermore, the upper rail 31 includes a removable cover plate 311. Users can remove the cover plate 311 to facilitate the disassembly and adjustment of the internal structure of the upper rail 31.

[0054] Furthermore, the first motor 1, the second motor 2, the power module 11, and the electronic control module 10 are arranged in a straight line within the upper rail 31. This straight-line arrangement minimizes the width of the upper rail 31, resulting in a more aesthetically pleasing ceiling curtain design.

[0055] Furthermore, the sun curtain includes a first support line 17, which consists of two lines. One end of the first support line 17 is fixedly connected to the upper rail 31. The first support line 17 is set along the opening and closing direction of the sun curtain, passes through the first fabric 41, and is guided by the first guide member 18 on the first transfer rail 42. It extends towards the end of the first transfer rail 42 and then towards the lower rail 32. The other end of the first support line 17 is connected to the second winding device 1611 on the lower end cap 161, so that the first support line 17 can be tightened by rotating the second winding device 1611.

[0056] The night curtain includes two second support lines 19. One end of the second support line 19 is fixedly connected to the lower rail 32. The second support line 19 is set through the second fabric 51 along the opening and closing direction of the night curtain and guided by the second guide member 20 on the second transfer rail 52. It extends towards the end of the second transfer rail 52 and then towards the upper rail 31. The other end of the second support line 19 is connected to the first winding device 1511 on the upper end cap 151 so that the second support line 19 can be tightened by rotating the first winding device 1511.

[0057] The first guide member 18 and the second guide member 20 are roller structures or have an arc surface structure, used to guide the first support line 17 and the second support line 19 to change direction.

[0058] It should be noted that during the use of the skylight blinds, the first and second support lines are taut and stationary, and are not used to drive the opening and closing of the day and night blinds. The first and second support lines only serve to support the first and second fabrics. Specifically, since the skylight blinds are installed horizontally or at an angle, and the first and second fabrics are soft materials, when the opening area of ​​the day and night blinds is large, the middle part of the first and second fabrics (the middle area in the opening and closing direction) will collapse under the influence of gravity. The first and second support lines, threaded inside the first and second fabrics, can support the first and second fabrics and prevent them from collapsing.

[0059] Compared with the prior art, the technical advantages of this utility model are as follows:

[0060] The first and second transmission mechanisms of this utility model realize the power transmission between the motor and the moving rail through gear pairs, rotating shafts, pulley assemblies, and trolleys, which has the advantages of stable power transmission and smooth and reliable opening and closing of day and night curtains.

[0061] The motor and the rotating shaft are set to be opposite to each other and are driven by a gear pair. When disassembling and assembling the motor, it is not necessary to disassemble and assemble the rotating shaft at the same time. In addition, the motor mounting components can be quickly connected to the upper rail 31, which also has the advantage of convenient motor disassembly and assembly.

[0062] By designing the electronic control module 10 and the power supply module 11 inside the upper rail 31, the integration is high, the appearance is beautiful, and the problem of the electronic control module 10 and the power supply module 11 being exposed to the sun and rain, which affects their service life, can be avoided.

[0063] By arranging the first motor 1, the second motor 2, the power module 11, and the electrical control module 10 in a straight line inside the upper rail 31, the width of the upper rail 31 can be minimized, making the width of the upper rail 31 close to the width of other rails, resulting in a more harmonious and aesthetically pleasing overall shape of the skylight curtain.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
