[0002] The drive motor structure for a corded Venetian blind disclosed in CN213144336U includes an upper fixed plate and a lower fixed plate. A corded gear 1 and a corded gear 2 are rotatably connected between the upper fixed plate and the lower fixed plate. The inner side of the upper fixed plate and / or the lower fixed plate has a tubular positioning pin. The corded gear 1 and the corded gear 2 are respectively sleeved around the corresponding positioning pin.

[0003] The end face of its positioning pin has several expansion portions arranged circumferentially. An adjusting screw is screwed into the positioning pin. The outer circumferential surface of the adjusting screw has a conical expansion section. When the adjusting screw is fed inward, the expansion section can drive the expansion portion to expand radially outward and increase the resistance of the rotation of the first and second pull rope gears.

[0004] The technical solution in the prior art document is easier to install and debug, but the defects are also more obvious. For example, when operating the Venetian blinds, it is still necessary to manually operate the device to move the pull beads to drive the Venetian blinds to open and close. The degree of automation is low and the structure is relatively complex. This solution is not very convenient for opening and closing Venetian blinds. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drive motor structure for Venetian blinds, which solves the problem that when operating Venetian blinds, it is still necessary to manually operate the device to move the pull beads to drive the Venetian blinds to open and close, resulting in low automation and a relatively complex structure. This solution is not very convenient for opening and closing Venetian blinds.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drive motor structure for a Venetian blind, including a drive motor, a quick-release assembly fixedly connected to the output end of the drive motor, a drive assembly fixedly connected to the side of the quick-release assembly, and a remote control template provided on the back of the drive motor;

[0007] The drive assembly includes a coil fixedly connected to the side of the quick-release assembly. The coil has a rotatable sleeve inside, and the surface of the sleeve has several grooves arranged in a circular array. The side of the sleeve has a socket, and the inside of the socket has a limit structure arranged axially symmetrically.

[0008] In one specific embodiment, the limiting structure includes a sleeve hole opened inside the insertion hole, and a spring is sleeved inside the sleeve hole, with one end of the spring fixedly connected to a limiting bead.

[0009] In one specific embodiment, the inner diameter of the groove matches the outer diameter of the Venetian blind bead, and the bottom surface of the coil has an opening for moving the bead.

[0010] In one specific embodiment, a plug rod is inserted into the inside of the socket, and a limiting groove that matches the limiting bead is opened on the surface of the plug rod. One end of the plug rod is fixedly connected to a side plate.

[0011] In one specific embodiment, the quick-release assembly includes a square tube fixedly connected to the output end of the drive motor, and a square rod is inserted inside the square tube. Limiting holes are provided on the sides of both the square tube and the square rod, and a limiting rod is inserted inside the limiting holes.

[0012] In one specific embodiment, both ends of the limiting rod are provided with circular holes, and elastic inserts for limiting are inserted into the inside of the circular holes.

[0013] Compared with the prior art, this utility model provides a drive motor structure for a Venetian blind, which has the following advantages:

[0014] In the technical solution disclosed in this utility model, the pull beads of the Venetian blinds are placed inside the coil. The pull beads are aligned with the grooves opened on the surface of the coil. The drive motor drives the coil to rotate through the quick-release assembly fixed at the output end, so that the grooves on the surface drive the pull beads to start moving, automatically opening and closing the Venetian blinds.

[0015] The drive assembly of this invention places the beaded string of the Venetian blinds inside the coil, aligns the beaded string with the groove on the surface of the coil, and inserts the rod fixed to the side of the side panel into the insertion hole on the side of the coil. The spring returns, causing the limit bead to reset and engage with the limit groove on the side of the rod, completing the installation of the side panel. Then, the drive motor is controlled by the remote control module to start working, causing the quick-release assembly fixed to its output end to rotate. The quick-release assembly causes the coil fixed to the side to rotate, moving the beaded string that fits in the groove on the surface of the coil, thus opening and closing the Venetian blinds. This achieves the effect of moving the beaded string without manual operation, improving automation and simplifying the structure. Attached Figure Description

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figures 1-4 As an embodiment of the present invention, a drive motor structure for a Venetian blind includes a drive motor 1, a quick-release assembly 2 fixedly connected to the output end of the drive motor 1, a drive assembly 3 fixedly connected to the side of the quick-release assembly 2, and a remote control template provided on the back of the drive motor 1.

[0024] The specific problem addressed in this embodiment is that the operation of Venetian blinds still requires manual movement of the pull beads to open and close the blinds, resulting in low automation and a complex structure, which makes the operation of Venetian blinds inconvenient. This invention utilizes a device where the pull beads of the Venetian blinds are placed inside a coil 31. The pull beads are aligned with grooves on the surface of a mounting plate 32. A drive motor 1, via a quick-release assembly 2 fixed to its output end, rotates the mounting plate 32, causing the grooves on the surface to move the pull beads, thus automating the opening and closing of the Venetian blinds.

[0025] The drive assembly 3 includes a coil 31 fixedly connected to the side of the quick-release assembly 2. The coil 31 has a rotatable sleeve 32 inside, and the surface of the sleeve 32 has a plurality of grooves arranged in a circular array. The side of the sleeve 32 has an insertion hole, and the inside of the insertion hole is symmetrically provided with a limiting structure 33. In this specific embodiment, the limiting structure 33 includes a sleeve hole opened inside the insertion hole, and a spring 331 is sleeved inside the sleeve hole. One end of the spring 331 is fixedly connected to a limiting bead 332. The beaded string of the Venetian blinds is placed inside the coil 31. The beaded string is then aligned with the groove on the surface of the sleeve 32. The insert rod 4, which is fixed to the side of the side panel 5, is inserted into the insertion hole on the side of the sleeve 32. The spring 331 rebounds, causing the limit bead 332 to reset and engage with the limit groove on the side of the insert rod 4, thus completing the installation of the side panel 5. Then, the drive motor 1 is controlled by the remote control module to start working, driving the quick-release assembly 2 fixed at its output end to rotate. The quick-release assembly 2 drives the sleeve 32 fixed to the side to rotate, causing the beaded string that fits in the groove on the surface of the sleeve 32 to move, opening and closing the Venetian blinds. This achieves the effect of moving the beaded string without the need for a manual operating device, improving the degree of automation and simplifying the structure.

[0026] In this specific embodiment, the quick-release assembly 2 includes a square tube 21 fixedly connected to the output end of the drive motor 1, and a square rod 22 is inserted inside the square tube 21. Limiting holes are opened on the sides of both the square tube 21 and the square rod 22, and limiting rods 23 are inserted inside the limiting holes. Both ends of the limiting rods 23 are provided with round holes, and elastic inserts 6 for limiting are inserted inside the round holes. The drive motor 1 is an electrical device with a certain probability of failure. When it needs to be replaced or repaired, the elastic inserts 6 and the limiting rods 23 can be pulled out in sequence, so that the square rod 22 is separated from the square tube 21, and further the drive motor 1 fixed on the side of the square tube 21 and the coil 31 fixed at one end of the square rod 22 are separated, thus completing the disassembly of the drive motor 1 and facilitating its replacement and repair.
