Description

Technical Field

[0001] This invention relates to the field of electric skylight blinds, and more particularly to an electric skylight blind that is easy and quick to assemble. Background Technology

[0002] Electric skylight blinds typically consist of a window frame with drive belts on both sides. A drive motor at the top of the frame synchronously drives these belts. The upper part of the curtain body is fixedly connected to the top of the frame, and the lower part connects to a movable beam. Both ends of the movable beam are connected to the belts on either side. The synchronous transmission of the belts causes the movable beam to slide up and down along the window frame, thus opening and closing the curtain. This type of electric skylight blind requires extremely high horizontality of the movable beam, posing significant safety challenges. If the movable beam is not level after assembly, light leakage is likely. Traditionally, a dual-output shaft drive motor is used to drive the belts. One output shaft of the drive motor is directly connected to the upper end of one belt, while the other output shaft needs to be connected to a transmission rod via a connecting sleeve before connecting to the upper end of the other belt. The current assembly structure is complex, and the connecting sleeve is prone to slippage. Over time, the transmission at both ends will deviate, causing the moving crossbeam to be non-level, resulting in light leakage. Moreover, the cost of dual-output shaft drive motors is also high. Currently, there are also single-output shaft drive motors on the market that use gear assemblies to drive the transmission rod, which is then connected to belts on both sides. Although single-output shaft drive motors are cheaper, it is difficult to level the moving crossbeam, making it very easy for light to leak. This is because the transmission rods are mostly square or hexagonal structures with an angular deviation of 90 degrees or 60 degrees. After one side of the belt is connected, the other side will have an angular deviation, making it difficult to assemble the moving crossbeam horizontally. During assembly, the belts on both sides need to be carefully adjusted to ensure that the moving crossbeam can be assembled horizontally. This requires extremely high skill from the assemblers, and the assembly is troublesome, difficult, time-consuming, and labor-intensive. Summary of the Invention

[0003] In view of the current state of the prior art, the technical problem to be solved by the present invention is to provide an electric skylight blind that is easy and quick to assemble, saves time and effort in installation, and ensures that the moving beam is installed horizontally and is not prone to light leakage.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an electric skylight blind that is easy and quick to assemble, including a blind frame, which is formed by an upper rail, a lower rail and two side rails. A blind body is provided inside the blind frame. The upper end of the blind body is fixedly connected to the upper rail. The lower end of the blind body is connected to a movable crossbeam. The movable crossbeam slides with the blind frame along the opening and closing direction of the blind body. A single-output motor and a transmission rod are provided in the upper rail. The single-output motor drives the transmission rod through a gear assembly. The single-output motor and the transmission rod are arranged vertically parallel. Each side rail is provided with a belt assembly. The belt assembly drives the transmission rod and the movable crossbeam. The transmission rod has a first end and a second end. The first end of the transmission rod is connected to the belt assembly on one side through a quick connector. The second end of the transmission rod is connected to the belt assembly on the other side.

[0005] Furthermore, the belt assembly includes a drive pulley, a belt, and a driven pulley. The two ends of the belt are respectively fitted onto the drive pulley and the driven pulley. The drive pulley is located at the upper end of the side rail, and the driven pulley is located at the lower end of the side rail. The first end of the transmission rod is connected to the drive pulley of one side of the belt assembly via a quick connector. This drive pulley is the first drive pulley. The second end of the transmission rod is connected to the drive pulley of the other side of the belt assembly. This drive pulley is the second drive pulley. The first drive pulley has an external spline integrally formed on it. One end of the quick connector has an internal spline that mates with the external spline, and the other end has a connecting groove that connects to the transmission rod. The second drive pulley has a connecting hole that connects to the transmission rod. The first drive pulley, the second drive pulley, and the transmission rod rotate synchronously.

[0006] Furthermore, the single-output motor is located at one end of the upper rail and close to the first end of the transmission rod. The gear assembly includes an input gear and an output gear. The input gear meshes with the output gear for transmission. The output end of the single-output motor is connected to the input gear for transmission. The first end of the transmission rod is in transmission engagement with the output gear, and the output gear is in transmission engagement with the first drive wheel.

[0007] Furthermore, the gear assembly also includes at least one transition gear that meshes between the input gear and the output gear, the output gear being integrally formed with the first drive wheel.

[0008] Furthermore, a shock-absorbing assembly is connected between the output end of the single-output motor and the input gear. The shock-absorbing assembly includes an input head, an output head, and a shock-absorbing sleeve. The input head is connected to the output end of the single-output motor, the output head is connected to the input gear, and the shock-absorbing sleeve is connected between the input head and the output head to prevent direct contact between the input head and the output head. The shock-absorbing sleeve is a flexible shock-absorbing sleeve.

[0009] Furthermore, the input head extends towards the end of the shock-absorbing sleeve with symmetrically arranged first protrusions, and the output head extends towards the end of the shock-absorbing sleeve with symmetrically arranged second protrusions. The shock-absorbing sleeve is provided with grooves for the first protrusions and the second protrusions to be inserted at intervals, and the length of the grooves is greater than the length of the first protrusions and the second protrusions.

[0010] Furthermore, the two ends of the movable crossbeam are fixedly connected to the belts on both sides by fasteners, and the movable crossbeam is synchronously driven by the belts on both sides.

[0011] Furthermore, the upper rail is provided with a first mounting cavity, a second mounting cavity and a third mounting cavity from top to bottom. The first mounting cavity is used to install a single-output motor, the second mounting cavity is used to install a transmission rod, and the third mounting cavity is used to install the upper end of the curtain body. The first mounting cavity is provided with a positioning component for limiting the single-output motor at the opposite end of the output end of the single-output motor.

[0012] Furthermore, the first mounting cavity is provided with a motor mounting position for mounting a single-output motor and a power supply mounting position for mounting a power supply. The positioning member is located between the motor mounting position and the power supply mounting position. The power supply mounting position contains a power supply, and the single-output motor is electrically connected to the power supply.

[0013] Furthermore, the front end face of the upper rail is a rotatable flip-top structure.

[0014] Furthermore, the upper rail is connected to the two side rails by upper connecting corner covers, namely the first upper connecting corner cover and the second upper connecting corner cover. The lower rail is connected to the two side rails by lower connecting corner covers. Each lower connecting corner cover is provided with a driven wheel mounting position. The first upper connecting corner cover is provided with an input gear mounting position, a transition gear mounting position and a first driving wheel mounting position in sequence. The second upper connecting corner cover is provided with a second driving wheel mounting position.

[0015] Furthermore, the second upper connecting corner cover is provided with a through hole communicating with the second drive wheel mounting position, and the through hole corresponds to the connecting hole so that the transmission rod can pass through.

[0016] Furthermore, the single-output motor has an exposed antenna for receiving signals, and the first upper connecting corner cover has an antenna mounting position for mounting the antenna, which is located above the input gear mounting position.

[0017] Furthermore, the electric skylight curtain also includes two symmetrically arranged pull cords, namely a first pull cord and a second pull cord. The upper end of the first pull cord is fixedly connected to the upper rail, and the lower end of the first pull cord passes through the curtain body, exits from the left side of the moving beam, and is fixedly connected to the lower connecting corner cover or the lower rail. The upper end of the second pull cord is fixedly connected to the upper rail, and the lower end of the second pull cord passes through the curtain body, exits from the right side of the moving beam, and is fixedly connected to the lower connecting corner cover or the lower rail.

[0018] Compared with the prior art, the advantages of the present invention are as follows: The present invention sets up a quick connector to connect the transmission rod to one of the belt assemblies, so that after the transmission rod is connected to one of the belt assemblies, it can quickly connect to another belt assembly without affecting the horizontal installation of the moving crossbeam, reducing assembly difficulty, improving assembly efficiency, and achieving rapid assembly. The quick connector can ensure that the transmission does not slip, reduce the deviation of the assembly angle, avoid the tilting of the moving crossbeam, reduce rework, and improve work efficiency.

[0039] The present invention will be further described below with reference to specific embodiments.

[0040] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] like Figure 1 , 2 As shown, a convenient and quick-assembly electric skylight blind includes a curtain frame 1, which is formed by an upper rail 1.1, a lower rail 1.2, and two side rails 1.3. A curtain body 2 is housed within the curtain frame 1. The upper end of the curtain body 2 is fixedly connected to the upper rail 1.1, and the lower end of the curtain body 2 is connected to a movable crossbeam 3. The movable crossbeam 3 slides along the opening and closing direction of the curtain body 2 with the curtain frame 1. A single-output motor 4 and a transmission rod 5 are housed within the upper rail 1.1. The single-output motor 4 drives the transmission rod 5 via a gear assembly 6. The output motor 4 and the transmission rod 5 are arranged vertically parallel to avoid mutual interference. Each side rail 1.3 is equipped with a belt assembly 7, which drives the transmission rod 5 and the moving beam 3. Through the transmission of the belt assembly 7, the moving beam 3 is driven to slide up and down along the curtain frame 1, thereby realizing the electric opening and closing of the curtain. The transmission rod 5 has a first end 5.1 and a second end 5.2. The first end 5.1 of the transmission rod 5 is connected to the belt assembly 7 on one side through a quick connector 8, and the second end 5.2 of the transmission rod 5 is connected to the belt assembly 7 on the other side.

[0045] This invention connects the transmission rod 5 to one of the belt assemblies 7 via a quick connector 8. This allows the transmission rod 5 to quickly connect with another belt assembly 7 after being connected to the first one, without affecting the horizontal installation of the moving crossbeam 3. This reduces assembly difficulty, improves assembly efficiency, and enables rapid assembly. The quick connector 8 ensures that the transmission does not slip and reduces the deviation of the assembly angle, preventing the moving crossbeam 3 from tilting, reducing rework, and improving work efficiency. Furthermore, a single-output motor 4 can be used to replace the original dual-output motor, reducing costs.

[0046] Among them, see Figure 2-6The belt assembly 7 includes a drive pulley, a belt 7.3, and a driven pulley 7.4. The two ends of the belt 7.3 are respectively fitted onto the drive pulley and the driven pulley 7.4. The drive pulley is located at the upper end of the side rail 1.3, and the driven pulley 7.4 is located at the lower end of the side rail 1.3. The first end 5.1 of the transmission rod 5 is connected to the drive pulley of one side of the belt assembly 7 via a quick connector 8; this drive pulley is the first drive pulley 7.1. The second end 5.2 of the transmission rod 5 is connected to the drive pulley of the other side of the belt assembly 7; this drive pulley is the second drive pulley 7.2. The first drive pulley 7.1 has an integrally formed external spline 7.1.1. One end of the quick connector 8 has an internal spline 8.1 that mates with the external spline 7.1.1. It should be noted that the positions of the internal spline and the external spline... The components are interchangeable, with the preferred structure described above facilitating quick and easy insertion without requiring careful alignment. The other end of the quick connector 8 has a connecting groove 8.2 for connecting to the transmission rod 5. The second drive wheel 7.2 has a connecting hole 7.2.1 for connecting to the transmission rod 5. During assembly, the first end 5.1 of the transmission rod 5 passes through the connecting hole 7.2.1 and inserts into the connecting groove 8.2 of the quick connector 8. Then, the inner spline 8.1 of the quick connector 8 connects to the outer spline 7.1.1 on the first drive wheel 7.1, achieving quick assembly without the need for time to calibrate the angle. The angle deviation is small, preventing the moving beam 3 from tilting due to angle deviation. If the existing cross-section is taken as square... Taking a shaped transmission rod as an example, without a quick-connect coupling, both the first and second drive wheels have connecting holes that match the cross-sectional shape of the transmission rod. When the transmission rod passes through the connecting hole of the second drive wheel, it is crucial that the connecting holes of the first and second drive wheels are perfectly aligned. Even a slight deviation will prevent the transmission rod from smoothly connecting to the first drive wheel. Since the lower moving beam has already been leveled and installed, the misalignment necessitates rework and readjustment of the belt assemblies on both sides. This ensures that the moving beam is horizontally installed while maintaining perfect alignment between the connecting holes of the first and second drive wheels. This perfect alignment means that when the first and second drive wheels are axially aligned, the connecting holes completely overlap. Since there is no angular deviation, the existing structure is difficult to install. However, the quick connector 8 uses an internal spline 8.1 and an external spline 7.1.1 mating structure, making the outer peripheral assembly structure almost as close to a cylindrical structure. Therefore, even if there is an angular deviation when the transmission rod 5 is inserted into the connecting hole 7.2.1 of the second drive wheel 7.2, it will not affect the docking of the quick connector 8, greatly reducing the installation difficulty and rework. The first drive wheel 7.1, the second drive wheel 7.2 and the transmission rod 5 rotate synchronously. The shape of the connecting groove 8.2 and the connecting hole 7.2.1 is the same as the cross-sectional shape of the transmission rod 5, such as a regular square, regular pentagon, regular hexagon, etc., thereby ensuring that the transmission rod 5 can link the quick connector 8, the second drive wheel 7.2 and the first drive wheel 7.1.

[0047] Among them, see Figure 2 , 6 11. The single-output motor 4 is located at one end of the upper side rail 1.1 and near the first end 5.1 of the transmission rod 5. The gear assembly 6 includes an input gear 6.1 and an output gear 6.2. The input gear 6.1 and the output gear 6.2 mesh and transmit power. The output end of the single-output motor 4 is connected to the input gear 6.1. The first end 5.1 of the transmission rod 5 is connected to the output gear 6.2, and the output gear 6.2 is connected to the first driving wheel 7.1. Specifically, the output gear 6.2 can be coaxially connected to the first driving wheel 7.1 for synchronous transmission, or the output gear 6.2 and the first driving wheel 7.1 can be integrally formed, with the output gear 6.2 formed between the first driving wheel 7.1 and the external spline 7.1.1. 1.1 The inner spline 8.1 of the quick connector 8 is connected to the quick connector 8. The connecting groove 8.2 of the quick connector 8 is sleeved with the first end 5.1 of the transmission rod 5. The single output motor 4 outputs power to drive the input gear 6.1 to rotate. The input gear 6.1 drives the output gear 6.2. The output gear 6.2, the first driving wheel 7.1, and the outer spline 7.1.1 are an integral structure that rotate together. The outer spline 7.1.1 is linked to the quick connector 8. The quick connector 8 is linked to the transmission rod 5. The transmission rod 5 is linked to the second driving wheel 7.2. The second driving wheel 7.2 winds the belt 7.3. The first driving wheel 7.1 winds the belt 7.3, thereby synchronously moving the horizontal beam 3 to slide up and down to open and close the curtain. The gear assembly 6 not only transmits power but also reduces speed and changes the direction of power transmission.

[0048] The gear assembly 6 further includes at least one transition gear 6.3, which meshes between the input gear 6.1 and the output gear 6.2. The transition gear 6.3 can further reduce speed and can accommodate the vertical distance between the single output motor 4 and the transmission rod 5. When the vertical distance between the single output motor 4 and the transmission rod 5 is large, multiple transition gears 6.3 can be installed. The specific assembly can be selected according to the actual structure. The attached figure shows an example of adding one transition gear 6.3.

[0049] Among them, see Figure 7 , 8To reduce the operating noise of the single-output motor 4, a vibration damping assembly 9 is connected between the output end of the single-output motor 4 and the input gear 6.1. The vibration damping assembly 9 includes an input head 9.1, an output head 9.2, and a vibration damping sleeve 9.3. The input head 9.1 is connected to the output end of the single-output motor 4, the output head 9.2 is connected to the input gear 6.1, and the vibration damping sleeve 9.3 is connected between the input head 9.1 and the output head 9.2 to prevent direct contact between them. As a flexible damping sleeve, a damping component 9 is added between the output end of the single-output motor 4 and the input gear 6.1 to reduce noise. In this damping component 9, a damping sleeve 9.3 is used as a transition between the output head 9.2 and the input head 9.1. This not only enables power transmission but also transforms a rigid connection into a flexible connection, reducing vibration and noise. The rigid connection refers to the direct connection of non-flexible material components, which results in greater noise. The flexible connection refers to the addition of a flexible material transition connection between non-flexible material components, which weakens vibration and reduces noise.

[0050] The input head 9.1 extends symmetrically with a first protrusion 9.1.1 towards the end facing the shock-absorbing sleeve 9.3, and the output head 9.2 extends symmetrically with a second protrusion 9.2.1 towards the end facing the shock-absorbing sleeve 9.3. The shock-absorbing sleeve 9.3 has a groove 9.3.1 for the first protrusion 9.1.1 and the second protrusion 9.2.1 to interlock. The length of the groove 9.3.1 is greater than the length of the first protrusion 9.1.1 and the second protrusion 9.2.1. The first protrusion 9.1.1 and the second protrusion 9.2.1 are interlocked with the groove 9.3.1 on the shock-absorbing sleeve 9.3, which makes the force more balanced and the transmission more stable during transmission. In addition, the length of the groove 9.3.1 is greater than the length of the first protrusion 9.1.1 and the second protrusion 9.2.1, ensuring that the input head 9.1 and the output head 9.2 do not come into contact at all, realizing a soft connection to transmit power, reducing vibration and noise.

[0051] Among them, see Figure 2 The two ends of the movable crossbeam 3 are fixedly connected to the belts 7.3 on both sides through the fixing parts 10. The movable crossbeam 3 and the belts 7.3 on both sides are synchronously driven to ensure that the movable crossbeam 3 slides horizontally up and down and is not prone to tilting and light leakage.

[0052] Among them, see Figure 2 , 9The upper rail 1.1 is provided with a first mounting cavity 1.1.1, a second mounting cavity 1.1.2, and a third mounting cavity 1.1.3 from top to bottom. The first mounting cavity 1.1.1 is used to install the single-output motor 4, the second mounting cavity 1.1.2 is used to install the transmission rod 5, and the third mounting cavity 1.1.3 is used to install the upper end of the curtain body 2. The first mounting cavity 1.1.1 has a positioning member 11 for limiting the single-output motor 4 at the opposite end of the output end of the single-output motor 4. The positioning member 11 can prevent the single-output motor 4 from sliding axially and play a role in limiting and fixing it. As a preferred embodiment, see [reference]. Figure 16 The positioning component 11 can be a fixing block, which has expansion holes (not shown in the figure) for screwing in screws. During installation, the fixing block is slid into the first mounting cavity 1.1.1 and placed at the tail of the single-output motor 4 for pre-positioning. Then, the screws are screwed into the expansion holes, causing the fixing block to expand towards both sides of the first mounting cavity 1.1.1, thereby abutting against both sides of the first mounting cavity 1.1.1. The fixing support is installed in the first mounting cavity 1.1.1, achieving axial limitation of the single-output motor 4. This structure does not require screw holes in the first mounting cavity 1.1.1, reducing damage to the upper rail 1.1, and is also more aesthetically pleasing. As another preferred option, see [reference needed]. Figure 14 , 15 The positioning component 11 is a fixing clip with screw holes. During installation, the fixing clip is slid into the first mounting cavity 1.1.1 and positioned at the tail of the single-output motor 4. Then, screws are screwed into the screw holes. As the screws are turned, the fixing clip moves upward along the screws until it is pressed or locked against the edge of the first mounting cavity 1.1.1. The pressing structure can be that the end of the folded edge of the fixing clip is pressed against the stepped surface of the edge of the first mounting cavity 1.1.1. The locking structure can be that the edge of the first mounting cavity 1.1.1 has a locking position, and the fixing clip has a hook that engages with the locking position, thereby fixing the fixing clip in the first mounting cavity 1.1.1 and achieving axial positioning of the single-output motor 4. This structure does not require screw holes in the first mounting cavity 1.1.1, reducing damage to the upper rail 1.1 and making the structure more aesthetically pleasing.

[0053] Among them, see Figure 2 , 1416. The first mounting cavity 1.1.1 is provided with a motor mounting position 1.1.1.1 for mounting a single-output motor 4 and a power supply mounting position 1.1.1.2 for mounting a power supply 12. The positioning member 11 is located between the motor mounting position 1.1.1.1 and the power supply mounting position 1.1.1.2. The power supply mounting position 1.1.1.2 is provided with a power supply 12. The single-output motor 4 is electrically connected to the power supply 12. The above structure has high space utilization, compact structure, and the power supply 12 and the single-output motor 4 are not easy to slide or shift freely, and the power supply 12 and the single-output motor 4 will not interfere with each other.

[0054] Among them, see Figure 2 , 9 10. To facilitate the installation, maintenance, and replacement of the power supply 12 and the single-output motor 4, the front end face 1.1.4 of the upper rail 1.1 is a rotatable flip-top structure, which is convenient for opening and closing and easier to use. As a preferred flip-top structure, the top of the upper rail 1.1 is provided with a hinge shaft, and the top of the front end face 1.1.4 is provided with a hinge groove that rotatably engages with the hinge shaft. Through the hinge engagement between the hinge shaft and the hinge groove, the front end face 1.1.4 can be flipped, making it convenient for opening and closing. It should be noted that the positions of the hinge groove and the hinge shaft can be interchanged and are not limited to one. In addition, the flip-top structure can also be implemented with other hinge structures or magnetic structures, as long as it can achieve the flipping and opening of the front end face 1.1.4, which will not be elaborated further.

[0055] Among them, see Figure 1 , 2 11, 12, 13. The upper rail 1.1 is connected to the two side rails 1.3 by upper connecting corner covers, namely the first upper connecting corner cover 1.4 and the second upper connecting corner cover 1.5. The lower rail 1.2 is connected to the two side rails 1.3 by a lower connecting corner cover 1.6. Each lower connecting corner cover 1.6 is provided with a driven wheel mounting position 1.6.1. The first upper connecting corner cover 1.4 is provided with an input gear mounting position 1.4.1, a transition gear mounting position 1.4.2 and a first driving wheel mounting position 1.4.3 in sequence. The second upper connecting corner cover 1.5 is provided with a second driving wheel mounting position 1.5.1. The setting of the upper and lower connecting corner covers facilitates the assembly of the curtain frame 1 and the assembly of other components.

[0056] Among them, see Figure 12 The second upper connecting corner cover 1.5 is provided with a through hole 1.5.2 communicating with the second drive wheel mounting position 1.5.1. The through hole 1.5.2 corresponds to the connecting hole 7.2.1 for the transmission rod 5 to pass through. The through hole 1.5.2 is preferably circular to facilitate the transmission rod 5 to be quickly inserted. The through hole 1.5.2 is larger than the connecting hole 7.2.1 to facilitate the transmission rod 5 to be quickly connected with the connecting hole 7.2.1 when it is inserted.

[0057] Among them, see Figure 2 , 11 The single-output motor 4 has an exposed antenna 13 for receiving signals. The first upper connecting corner cover 1.4 has an antenna mounting position 1.4.4 for mounting the antenna 13. The antenna mounting position 1.4.4 is located above the input gear mounting position 1.4.1. Preferably, the antenna 13 is a PCB board antenna. Setting the antenna 13 inside the first upper connecting corner cover 1.4 can better receive signals. Moreover, the mounting position of the antenna 13 is compact, making better use of the mounting space of the first upper connecting corner cover 1.4. Furthermore, the first upper connecting corner cover 1.4 is made of non-conductive material, which is safe and does not shield the signal.

[0058] Among them, see Figure 17 The electric skylight curtain also includes two symmetrically arranged pull cords 14, namely a first pull cord and a second pull cord. The upper end of the first pull cord is fixedly connected to the upper rail 1.1, and the lower end of the first pull cord passes through the curtain body 2, exits from the left side of the moving beam 3, and is fixedly connected to the lower connecting corner cover 1.6 or the lower rail 1.2. The upper end of the second pull cord is fixedly connected to the upper rail 1.1, and the lower end of the second pull cord passes through the curtain body 2, exits from the right side of the moving beam 3, and is fixedly connected to the lower connecting corner cover 1.6 or the lower rail 1.2. The lower rail 1.2 is provided with corresponding cord fixing positions, and the lower connecting corner cover 1.6 is provided with cord fixing holes. The method of fixing the pull cords 14 can be selected according to the actual assembly structure. Figure 17 Taking the example of the lower end of the pull rope 14 being fixed on the lower rail 1.2, the pull rope 14 can support the curtain 2 and prevent the curtain 2 from collapsing or drooping during opening and closing. The curtain 2 can open and close along the pull rope 14, making the opening and closing smoother.

[0059] During assembly, after assembling the curtain frame 1, single-output motor 4, shock-absorbing assembly 9, gear assembly 6, belt assembly 7, curtain body 2, pull cord 14, and moving beam 3, adjust the moving beam 3 to a horizontal position. Then, the first end 5.1 of the transmission rod 5 passes through the through hole 1.5.2 and the connecting hole 7.2.1 from the side of the curtain frame 1, and is inserted into the connecting groove 8.2 of the quick connector 8. Then, the inner spline 8.1 of the quick connector 8 is sleeved with the outer spline 7.1.1 to achieve quick installation of the transmission rod 5 without affecting the horizontal position of the moving beam 3. To prevent light leakage caused by tilting of the moving beam 3, the quick-connect coupling 8 is designed with an internal spline 8.1 and an external spline 7.1.1 to minimize the impact of angular deviation, enabling rapid assembly, reducing rework, and improving work efficiency. When the curtain is in operation, the single-output motor 4 transmits power to the shock-absorbing component 9 through its output end. The shock-absorbing component 9 is linked to the input gear 6.1, which in turn links the transition gear 6.3 and the output gear 6.2. The output gear 6.2 drives the first drive wheel 7.1 and the external spline 7.1.1. Synchronous rotation, the external spline 7.1.1 is linked to the quick connector 8, the quick connector 8 is linked to the transmission rod 5, the transmission rod 5 is linked to the second drive wheel 7.2, the first drive wheel 7.1 and the second drive wheel 7.2 respectively drive the corresponding belts 7.3 to rotate, the two side belts 7.3 drive the moving beam 3 to keep horizontal and slide up and down along the opening and closing direction of the curtain 2, realizing the opening and closing of the curtain 2. In addition, it should be noted that when the present invention is installed on a building, it can be installed upright, that is, the upper side rail 1.1 is located at the top and the lower side rail 1.2 is located at the bottom, and the curtain 2 is installed from top to bottom. The curtain can be installed in two ways: it can be opened to block light and closed to let light in from bottom to top; it can also be installed in reverse, with the upper rail 1.1 at the bottom and the lower rail 1.2 at the top, with the curtain opening to block light from bottom to top and closing to let light in from top to bottom; it can also be installed on the side, with the upper rail 1.1 at the left and the lower rail 1.2 at the right, with the curtain opening to block light from left to right and closing to let light in from right to left; or, with the upper rail 1.1 at the right and the lower rail 1.2 at the left, with the curtain opening to block light from right to left and closing to let light in from left to right. The installation direction can be chosen according to people's usage habits.
