They are made by processing curtain fabric with resin, rolling it into a cylinder, and raising and lowering it using a pull cord or chain. They are simple and convenient to operate, and have a clean and aesthetically pleasing appearance, making window frames look neat and tidy, and the entire room appear spacious and minimalist.

The roller shutter rod is rotatably connected to the housing. The second gear is sleeved on the roller shutter rod and fixedly connected to it. The drive gear and the second gear mesh with each other. The sliding rotating component passes through the drive gear and is slidably engaged with it. The clutch drive component is used to drive the sliding rotating component to slide towards or away from the drive gear, and the sliding rotating component is used to drive the drive gear to rotate.

[0004] In actual operation, the electric roller shutter lift in related technologies suffers from uneven lifting and lowering of the shutter rod, prone to jamming and shaking. Especially after prolonged use, the wear of the gear mechanism accelerates, further impacting the equipment's reliability and lifespan. Furthermore, the clutch mechanism in existing technologies is relatively simple and cannot flexibly handle the manual and automatic switching needs in different scenarios, causing inconvenience for users. Utility Model Content

[0005] To improve the operating efficiency and stability of the system, this application provides a swing mechanism and a roller shutter lift.

[0006] The swing mechanism and roller shutter lift provided in this application adopt the following technical solution:

[0007] A swing mechanism includes a swing frame and a gear mechanism. The gear mechanism includes a drive gear and at least one intermediate gear. The drive gear is rotatably connected to the swing frame, and the intermediate gear is rotatably connected to the swing frame. The drive gear and the intermediate gear mesh with each other.

[0008] By adopting the above technical solution, the design of the swing mechanism enables the active gear and the intermediate gear to mesh, achieving efficient power transmission. The swing frame, as a support structure, ensures stable connection and reliable movement of all components. This design not only simplifies the mechanical structure and reduces manufacturing costs but also improves the operating efficiency and stability of the roller blind lift. Especially when applied to roller blind lifts, this swing mechanism effectively reduces jamming and shaking during the lifting process, enhancing the user experience.

[0009] Optionally, there are two intermediate gears, and the driving gear meshes with the two intermediate gears.

[0010] By adopting the above technical solution, the two intermediate gears work together in the transmission, reducing the transmission deviation caused by manufacturing errors or wear of a single gear and improving the accuracy of the overall transmission system. The design of the double intermediate gears distributes the load, reduces the pressure on a single gear, extends the service life of the gears, and enhances the reliability of the system under high load conditions. Multi-point meshing makes the power transmission more uniform, reduces vibration and impact, and improves the smoothness and quietness of equipment operation, which is especially suitable for applications that require frequent starts and stops. By rationally arranging the positions of the two intermediate gears, more complex mechanical actions can be achieved in a limited space, improving design flexibility and compactness.

[0011] Optionally, the swing frame includes a connecting shaft, a first swing block, and a second swing block. One end of the connecting shaft is connected to the first swing block, and the other end of the connecting shaft is connected to the second swing block. The intermediate gear corresponds one-to-one with the connecting shaft, and the intermediate gear is sleeved on the connecting shaft and rotatably connected to the connecting shaft.

[0012] By adopting the above technical solution, the swing frame includes a connecting shaft, a first swing block, and a second swing block. One end of the connecting shaft is connected to the first swing block, and the other end is connected to the second swing block. An intermediate gear corresponds one-to-one with the connecting shaft and is sleeved on it, rotatably connected to the connecting shaft. This design ensures that the intermediate gear maintains a stable rotational state during swinging, improving the accuracy and reliability of the transmission. Simultaneously, the two ends of the connecting shaft are connected to the first and second swing blocks respectively, enhancing the overall structural strength of the swing frame and enabling it to maintain good stability even under heavy loads. Furthermore, the mating design between the intermediate gear and the connecting shaft effectively reduces frictional loss and extends the service life of the device.

[0013] Optionally, a first guide cylinder is provided between the drive gear and the first swing block, the sliding rotating member passes through the first guide cylinder, the sliding rotating member slides and engages with the first guide cylinder, and the sliding rotating member is rotatably connected to the first guide cylinder; one side of the drive gear abuts against the first guide cylinder, the other side of the drive gear abuts against the second swing block, and the drive gear is rotatably disposed between the first guide cylinder and the second swing block.

[0014] By adopting the above technical solution, the design of the first guide cylinder between the drive gear and the first swing block, and the sliding rotating component passing through and sliding with the first guide cylinder, makes the sliding rotating component more stable during movement, reducing the possibility of wobbling and deviation. Simultaneously, the rotational connection design between the sliding rotating component and the first guide cylinder ensures smooth rotation of the sliding rotating component, reduces mechanical wear, and extends the service life of the equipment. Furthermore, the double-support structure, with one side of the drive gear abutting the first guide cylinder and the other side abutting the second swing block, further enhances the stability of the drive gear, making it more reliable during operation and avoiding imbalance problems caused by single-point support. Overall, these designs effectively improve the overall performance and reliability of the swing mechanism.

[0015] Optionally, a second guide cylinder is provided between the intermediate gear and the second swing block, and the connecting shaft passes through the second guide cylinder; one side of the intermediate gear abuts against the second guide cylinder, and the other side of the intermediate gear abuts against the second swing block, and the intermediate gear is rotatably disposed between the second swing block and the second guide cylinder.

[0016] By adopting the above technical solution, the second guide cylinder installed between the intermediate gear and the second swing block enhances the support stability of the intermediate gear and avoids wear and deformation problems caused by long-term use. This design not only improves the rotational accuracy of the intermediate gear but also extends the overall service life of the gear mechanism. Simultaneously, the design of the connecting shaft passing through the second guide cylinder allows the intermediate gear to rotate smoothly between the second swing block and the second guide cylinder, further improving the system's operational stability and reliability.

[0017] Optionally, a roller shutter lift includes the swing mechanism described in any of the above claims, and further includes a housing, with the swing mechanism located within the housing; the housing also includes a roller shutter rod, a clutch mechanism, and a drive mechanism; the clutch mechanism includes a sliding rotating member, a limiting member, and a clutch drive member, the sliding rotating member being slidably engaged with the housing and rotatably connected to the housing, and the drive mechanism being used to drive the sliding rotating member to rotate; the limiting member is disposed within the housing, the sliding rotating member being slidably engaged with the limiting member and rotatably connected to the limiting member; a swing frame is sleeved on the sliding rotating member and rotatably connected to the sliding rotating member, the swing frame being rotatably connected to the limiting member, and a gear mechanism being used to link the roller shutter rod and the swing frame; the sliding rotating member passes through the gear mechanism and is slidably engaged with the gear mechanism, and the clutch drive member is used to drive the sliding rotating member to slide towards or away from the drive mechanism.

[0018] By adopting the above technical solution, this lifting platform achieves a compact structure and comprehensive functionality through an integrated shell design incorporating a swing mechanism. The shell cleverly houses the roller shutter rod, clutch mechanism, and drive mechanism. The clutch mechanism consists of a sliding rotating component, a limiting component, and a clutch drive component; their sliding and rotating coordination ensures precise and smooth clutch operation. The drive mechanism drives the sliding rotating component to rotate, while the clutch drive component controls the sliding rotating component's proximity or distance from the drive mechanism, thus flexibly switching between clutch states. The swing frame is mounted on the sliding rotating component and is linked to the roller shutter rod via a gear mechanism, achieving efficient power transmission and roller shutter lifting and lowering control. This not only improves the automation and ease of operation of the roller shutter lifting but also enhances the overall structural stability and durability through the precise coordination between components, providing users with a more efficient and reliable roller shutter experience.

[0019] Optionally, a driven gear is fitted on the roller shutter rod, the driven gear is fixedly connected to the roller shutter rod, and the intermediate gear meshes with the driven gear.

[0020] By adopting the above technical solution, the driven gear is fixedly connected to the roller shutter rod, and the intermediate gear meshes with the driven gear. This allows the intermediate gear to effectively transmit power to the roller shutter rod during oscillation, thereby achieving smooth raising and lowering of the roller shutter. Furthermore, this meshing method improves the system's transmission efficiency and reliability, reduces jamming and vibration caused by gear backlash, and extends the equipment's service life.

[0021] Optionally, during the swinging process, at least one intermediate gear meshes with the driven gear.

[0022] By adopting the above technical solution, during the swinging process, at least one intermediate gear meshes with the driven gear. Since the roll material is wound on the roller shutter rod, the roller shutter will drive the roll material rod to rotate under its own weight. The roller shutter rod drives the driven gear to rotate. Since the worm gear structure is unstable under vibration, the driven gear drives one of the intermediate gears to rotate. The driving gear and the other intermediate gear have a limit function on the driven gear, thus effectively ensuring the stable rotation of the roll material rod and the smooth opening and closing of the roller shutter.

[0023] Optionally, the driven gear has a larger diameter than the driving gear, and the driven gear has a larger diameter than the intermediate gear.

[0024] By adopting the above technical solution, the diameter of the driven gear is larger than that of the driving gear and the intermediate gear. This design effectively increases the meshing contact area between the driven gear and the intermediate gear, improving the stability and reliability of the transmission system. Simultaneously, the larger diameter driven gear can better distribute the load, reducing the pressure on individual teeth and extending the gear's service life. Furthermore, the larger driven gear can also improve the transmission ratio, making the raising and lowering of the roller shutter rod smoother, avoiding jamming and shaking, and enhancing the user experience.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting the drive gear to mesh with at least one intermediate gear, stable power transmission can be maintained during the swinging process, effectively reducing the jamming and shaking during the raising and lowering of the roller shutter rod, and improving the reliability and service life of the equipment;

[0027] 2. The design of the intermediate gear and the driven gear meshing with each other ensures the power transmission efficiency of the gear mechanism even after long-term use, further enhancing the stability and durability of the system;

[0028] 3. The rotational connection between the swing frame and the sliding rotating component, as well as the linkage design of the gear mechanism, make the lifting and lowering action of the roller shutter rod smoother. At the same time, the clutch drive component can flexibly switch between manual and automatic modes, greatly improving the user's operational convenience and flexibility. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Unless otherwise defined, the technical or scientific terms used in this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0040] Example 1

[0041] This application provides a swing mechanism, referring to... Figure 1 and Figure 2The swing mechanism includes a swing frame 7 and a gear mechanism 8. The gear mechanism 8 includes a drive gear 81 and at least one intermediate gear 82. The drive gear 81 is rotatably connected to the swing frame 7, and the intermediate gear 82 is also rotatably connected to the swing frame 7. The drive gear 81 and the intermediate gear 82 mesh with each other. This improves the stability and reliability of the system and solves the problem of unstable lifting and lowering of the roller shutter rod 2 in the prior art.

[0042] Specifically, the swing frame 7 includes a connecting shaft 71, a first swing block 72, and a second swing block 73. One end of the connecting shaft 71 is connected to the first swing block 72, and the other end of the connecting shaft 71 is connected to the second swing block 73. An intermediate gear 82 corresponds one-to-one with the connecting shaft 71, and the intermediate gear 82 is sleeved on the connecting shaft 71 and rotatably connected to it. This design ensures the stability of the intermediate gear 82 during the swinging process and reduces wear caused by vibration.

[0043] Specifically, a first guide cylinder 74 is provided between the drive gear 81 and the first swing block 72. A sliding rotating member 3 passes through the first guide cylinder 74, and the sliding rotating member 3 is slidably engaged with the first guide cylinder 74 and rotatably connected to the first guide cylinder 74. One side of the drive gear 81 abuts against the first guide cylinder 74, and the other side of the drive gear 81 abuts against the second swing block 73. The drive gear 81 is rotatably disposed between the first guide cylinder 74 and the second swing block 73. This can further improve the positioning accuracy of the drive gear 81, reduce friction during operation, and extend the service life of the component. Specifically, a second guide cylinder 75 is provided between the intermediate gear 82 and the second swing block 73, and the connecting shaft 71 passes through the second guide cylinder 75. One side of the intermediate gear 82 abuts against the second guide cylinder 75, and the other side of the intermediate gear 82 abuts against the second swing block 73. The intermediate gear 82 is rotatably disposed between the second swing block 73 and the second guide cylinder 75. This design not only increases the stability of the intermediate gear 82, but also reduces the friction between the components, further improving the system's performance.

[0044] The implementation principle of this embodiment is as follows: by optimizing the design of the gear mechanism 8, especially by increasing the number of intermediate gears 82 and rationally arranging the various components, the entire system is made to operate more smoothly, reducing the wear rate and improving the reliability and service life of the equipment.

[0045] Example 2

[0046] This embodiment discloses a roller shutter lift, including the swing mechanism of Embodiment 1, and further including a housing 1, a roller shutter rod 2, a clutch mechanism, and a drive mechanism 6. The housing 1 houses the roller shutter rod 2, the clutch mechanism, and the drive mechanism 6. The clutch mechanism includes a sliding rotating member 3, a limiting member 4, and a clutch drive member 5. The sliding rotating member 3 is slidably engaged with the housing 1 and rotatably connected to it. The drive mechanism 6 drives the sliding rotating member 3 to rotate. The limiting member 4 is disposed within the housing 1, and the sliding rotating member 3 is slidably engaged with it and rotatably connected to it. A swing frame 7 is sleeved on the sliding rotating member 3 and rotatably connected to it. The swing frame 7 is rotatably connected to the limiting member 4. A gear mechanism 8 is used to link the roller shutter rod and the swing frame 7. The sliding rotating member 3 passes through the gear mechanism 8 and is slidably engaged with it. The clutch drive member 5 drives the sliding rotating member 3 to slide towards or away from the drive mechanism 6.

[0047] The housing 1 includes a mounting shell 11 and a cover 12. One side of the mounting shell 11 is open, and the cover 12 is fixed to the mounting shell 11 by multiple bolts, which increases the convenience for workers to install and remove the cover 12.

[0048] Reference Figure 3 The gear mechanism 8 also includes a driven gear 83, which is sleeved on the roller shutter rod 2 and fixedly connected to it. Intermediate gears 82 mesh with the driven gear 83. During the swinging process of the swing frame 7, at least one intermediate gear 82 meshes with the driven gear 83, thereby increasing the stability of the gear mechanism 8 transmission. In this embodiment, the diameter of the driven gear 83 is larger than the diameter of the driving gear 81, and the diameter of the driven gear 83 is larger than the diameters of the two intermediate gears 82.

[0049] Reference Figure 3 and Figure 4 The swing frame 7 is rotatably connected to the limiting member 4 via two rotatably connected rotating cylinders 9. The swing frame 7 includes a connecting shaft 71, a first swing block 72, and a second swing block 73. In this embodiment, there are two connecting shafts 71. One end of each connecting shaft 71 is connected to the first swing block 72, and the other end of each connecting shaft 71 is connected to the second swing block 73, thereby increasing the convenience for workers to install and disassemble the swing frame 7. An intermediate gear 82 corresponds one-to-one with the connecting shaft 71, and the intermediate gear 82 is sleeved on the connecting shaft 71 and rotatably connected to it. Both the first swing block 72 and the second swing block 73 are sleeved on the sliding rotating member 3. The first swing block 72 slides and is rotatably connected to the sliding rotating member 3.

[0050] Continue to refer to Figure 3and Figure 4 A first guide cylinder 74 is provided between the drive gear 81 and the first swing block 72. The sliding rotating member 3 passes through the first guide cylinder 74 and slides with the first guide cylinder 74. The sliding rotating member 3 is rotatably connected to the first guide cylinder 74. One side of the drive gear 81 abuts against the first guide cylinder 74, and the other side of the drive gear 81 abuts against the second swing block 73. The drive gear 81 is rotatably positioned between the first guide cylinder 74 and the second swing block 73, thereby increasing the stability of the rotation of the drive gear 81.

[0051] Reference Figure 4 The sliding rotating component 3 is rotatably connected to the housing 1, and simultaneously slides with the housing 1 and the drive gear 81. The clutch drive component 5 drives the sliding rotating component 3 to slide towards or away from the drive gear 81, thereby driving the drive gear 81 to rotate. The drive mechanism 6 is mounted on the housing 1 and drives the sliding rotating component 3 to rotate. Notably, when the sliding rotating component 3 slides into and meshes with the drive gear 81, the drive mechanism 6, while driving the sliding rotating component 3 to rotate, causes the drive gear 81 to rotate. The drive gear 81 then drives one of the intermediate gears 82 to rotate, or simultaneously drives both intermediate gears 82 to rotate. The intermediate gears 82 drive the driven gear 83 to rotate, and the driven gear 83 drives the roller shutter rod 2 to rotate, thus facilitating automated control of the roller shutter's opening and closing. When the sliding rotating part 3 slides to the outside of the driving gear 81, the sliding rotating part 3 disengages from the driving gear 81. At this time, the driving action of the driving mechanism 6 on the driving gear 81 is released, which makes it easier for the staff to manually rotate the roller shutter rod 2, thereby realizing the manual operation of the roller shutter.

[0052] Reference Figure 3 and Figure 4 In this embodiment, the limiting member 4 includes a first limiting block 41, a second limiting block 42, and three fixing rods 43. One end of each fixing rod 43 is fixedly connected to the first limiting block 41, and the other end of each fixing rod 43 abuts against the surface of the first limiting block 41. The first limiting block 41 and the second limiting block 42 are parallel to each other. Bolts are threaded through each of the three fixing rods 43. The end of the bolt away from the nut passes through the second limiting block 42 and is threaded into the housing 1. The nut of the bolt and the housing 1 have a clamping effect on the limiting rods and the second limiting block 42, thereby fixing the limiting member 4 inside the housing 1. One side of the driving gear 81 abuts against the inner sidewall of the housing 1, and the other side of the driving gear 81 abuts against the sidewall of the first limiting block 41, thereby increasing the rotational stability of the driving gear 81.

[0053] Continue to refer to Figure 3 and Figure 4The sliding rotating component 3 includes a sliding rod 31, a driving flange 32, and a sliding post 33. The sliding rod 31 and the sliding post 33 are respectively fixed to the two ends of the driving flange 32. A driving groove 85 is formed on the side of the drive gear 81 near the limiting component 4. The depth of the driving groove 85 is less than the thickness of the gear. The thickness of the driving flange 32 is the same as the depth of the driving groove 85, and the driving flange 32 and the driving groove 85 slide in engagement.

[0054] Reference Figure 3 and Figure 5 The drive mechanism 6 includes a worm gear 61, a worm 62, a motor 63, and a drive rod 64. The drive rod 64 is rotatably connected to the housing 1. The worm gear 61 is sleeved on the drive rod 64 and fixedly connected to it. The worm 62 is rotatably disposed inside the housing 1, and the worm gear 61 and the worm 62 mesh with each other. The motor 63 is fixedly mounted on the housing 1, and its output shaft is fixedly connected to the end of the worm 62. A connector 65 is fixedly mounted on the drive rod 64. A connector groove 332 is formed at the end of the sliding rotating part 3. The depth of the connector groove 332 is greater than the depth of the connector 65. The connector 65 is inserted into the connector groove 332, and the connector 65 slides in the connector groove 332. Because the clutch drive 5 drives the sliding rotating member 3 to slide towards or away from the drive gear 81, when the sliding rotating member 3 slides into the drive gear 81 and meshes with it, the insertion rod 65 slides into the insertion slot 332, and the depth of the insertion slot 332 is greater than the depth of the insertion rod 65. The cross-section of the insertion rod 65 is not circular; in this embodiment, the cross-section of the insertion rod 65 is a regular hexagon, and the insertion slot 332 is also a regular hexagonal slot. During the rotation, the insertion rod 65 can always drive the sliding rotating member 3 to rotate. When the worm gear 62 is driven to rotate by the motor 63, the worm gear 62 drives the worm wheel 61 to rotate, the worm wheel 61 drives the drive rod 64 to rotate, the drive rod 64 drives the insertion rod 65 to rotate, the insertion rod 65 drives the sliding rotating member 3 to rotate, the sliding rotating member 3 drives the drive gear 81 to rotate, the drive gear 81 drives the second gear to rotate, and the second gear drives the roller shutter rod 2 to rotate, thereby facilitating the automatic raising and lowering of the roller shutter.

[0055] Reference Figure 6 and Figure 7 Specifically, the clutch drive component 5 includes a drive block 51, which is movably mounted on the housing 1. A drive groove 511 is provided on the drive block 51, and the depth of one end of the drive groove 511 is greater than the depth of the other end of the drive groove 511.

[0056] Reference Figure 2 , Figure 3 and Figure 4The end of the sliding rod 31 away from the driving flange 32 slides into the driving groove 511. A convex ring 34 is fixedly provided on the outer wall of the sliding column 33. The clutch drive component 5 also includes a spring 52, which is sleeved on the sliding column 33. One end of the elastic element abuts against the convex ring 34, and the other end of the spring 52 abuts against the second limiting block 42. The convex ring 34 and the second limiting block 42 respectively limit the two ends of the spring 52. At the same time, as the sliding rotating component 3 slides towards the limiting component 4, the convex ring 34 and the second limiting block 42 exert a squeezing effect on the spring 52, thereby facilitating the storage of elastic potential energy by the spring 52.

[0057] Reference Figure 4 and Figure 6 In this embodiment, the drive block 51 is rotatably connected to the housing 1. Correspondingly, the drive groove 511 is an arc-shaped groove, and the center of the drive groove 511 coincides with the rotation center of the drive block 51, thereby ensuring that the end of the sliding rod 31 away from the sliding column is always located in the drive groove 511 during the rotation of the drive block 51.

[0058] Reference Figure 6 and Figure 7 A guide block 13 is fixedly installed on the outer wall of the cover 12, and a guide groove 512 is provided on the drive block 51. The guide block 13 is an arc-shaped block, and the guide groove 512 is an arc-shaped groove. The center of the guide block 13 coincides with the center of the drive groove 511, and the center of the guide groove 512 also coincides with the center of the drive groove 511. The guide block 13 and the guide groove 512 slide in fit. The guide block 13 and the guide groove 512 guide the drive block 51, increasing the stability of the drive block 51's movement. In this embodiment, the cross-section of both the guide block 13 and the guide groove 512 is L-shaped. Therefore, during the movement of the drive block 51, the guide block 13 not only guides the drive block 51 but also prevents it from detaching, further increasing the stability of the drive block 51's movement.

[0059] Continue to refer to Figure 6 and Figure 7 Of course, the drive block 51 can also slide with the housing 1. Correspondingly, the drive groove 511, guide block 13 and guide groove 512 are all waist-shaped grooves or rectangular grooves.

[0060] Reference Figure 4 and Figure 7 A limiting hole 513 is provided at the shallower end of the drive groove 511. When the end of the sliding rotating member 3 slides to the shallower end of the drive groove 511, the end of the sliding rotating member 3 abuts against the limiting hole 513. When the end of the sliding rotating member 3 abuts against the inside of the limiting hole 513, the limiting hole 513 has a limiting effect on the end of the sliding rotating member 3, thereby preventing the sliding rotating member 3 from sliding in the drive groove 511 under the action of the spring 52.

[0061] Continue to refer to Figure 4 and Figure 7 The width of the drive groove 511 is greater than the diameter of the sliding rod 31. Because the width of the drive groove 511 is greater than the diameter of the sliding rod 31, the friction between the sliding rod 31 and the drive groove 511 is reduced during the sliding process of the sliding rod 31 in the drive groove 511, so that the operator can control the movement of the drive block 51 with less force.

[0062] Continue to refer to Figure 4 and Figure 7 The end of the sliding rod 31 is hemispherical, and rounded corners 514 are provided on both opposite sides of the drive groove 511. The rounded corners 514 further reduce the friction between the sliding rod 31 and the drive groove 511, so that the operator can control the movement of the drive block 51 with less force.

[0063] Continue to refer to Figure 4 and Figure 7 When the end of the sliding rod 31 abuts against the deeper end of the drive groove 511, the drive flange 32 abuts against the inner wall of the drive groove 85. When the end of the sliding rod 31 abuts against the shallower end of the drive groove 511, the drive flange 32 moves to the outside of the drive groove 85. Since the sliding rotating member 3 includes the drive flange 32 and the drive gear 81 has a drive groove 85, and when the end of the sliding rod 31 abuts against the deeper end of the drive groove 511, the drive flange 32 abuts against the inner wall of the drive groove 85, the sliding rotating member 3 can easily drive the drive gear 81 to rotate during rotation. Therefore, the movement of the roller shutter rod 2 can be automatically controlled by the drive mechanism 6, thereby facilitating the automatic opening and closing of the roller shutter. When the end of the sliding rod 31 abuts against the shallower end of the drive groove 511, the drive flange 32 moves to the outside of the drive groove 85. At this time, although the drive mechanism 6 can drive the sliding rotating part 3 to rotate, since the drive flange 32 moves to the outside of the drive groove 85, the sliding rotating part 3 cannot drive the drive gear 81 to rotate during the rotation process. This makes it easier for the operator to manually control the roller shutter rod 2 to achieve the opening and closing of the roller shutter.

[0064] Continue to refer to Figure 4 and Figure 7When manual control of the roller blind retraction is required, the operator pushes the drive block 51 to move the end of the sliding rotating part 3 against the shallower end of the drive groove 511. During the movement, the drive block 51 pushes the sliding rotating part 3 towards the spring 52. At this time, the sliding rotating part 3 disengages from the drive gear 81, making it easier for the operator to manually control the roller blind retraction. At the same time, the sliding rotating part 3 compresses the spring 52, allowing the spring 52 to store elastic potential energy. When automatic control of the roller blind retraction is required, the operator pushes the drive block 51 to move the end of the sliding rotating part 3 against the deeper end of the drive groove 511. Under the action of the spring force of the spring 52, the sliding rotating part 3 moves towards the drive block 51, thereby engaging the sliding rotating part 3 with the drive gear 81. When the drive mechanism 6 drives the sliding rotating part 3 to rotate, the sliding rotating part 3 can easily drive the drive gear 81 to rotate, thus facilitating the automatic retraction of the roller blind.

[0065] The implementation principle of the above embodiment is as follows: the sliding rotating part 3 is driven to rotate by the drive mechanism 6, while the clutch drive part 5 controls the sliding rotating part 3 to slide within the housing 1, moving closer to or away from the drive mechanism 6 to achieve the clutch function. The sliding and rotational cooperation between the sliding rotating part 3 and the limiting part 4 ensures the stability and accuracy of the movement. The swing frame 7 is sleeved on the sliding rotating part 3 and linked with the gear mechanism 8, thereby controlling the lifting and lowering of the roller shutter rod 2. The entire mechanism is ingeniously designed, realizing stable and efficient lifting operation of the electric roller shutter lift, improving the reliability and ease of use of the equipment.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
