Description

Technical Field

[0001] This utility model relates to the field of electric curtains, and in particular to an embedded curtain motor. Background Technology

[0002] With the development of technology, smart homes are gradually becoming more common in daily life, with motorized curtains being the most widely used. Motorized curtains mainly consist of a motor, transmission box, track, and curtain fabric. Users can remotely control the motor to automatically open and close the curtains.

[0003] In real life, most users choose to cut grooves in the ceiling or suspended ceiling and then hide the rest of the structure except for the curtain in the grooves. However, the motors used in electric curtains are currently large. Even if the motor is placed at the deepest part of the groove, the tail of the motor will still be exposed on the ceiling, which is very abrupt and affects the overall visual appeal of the interior decoration. Therefore, miniaturization of curtain motors is an important research and development direction in the industry. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model proposes an embedded curtain motor, see reference. Figure 1 , 2 The system includes a positioning housing 1, a driving cavity 11 inside the positioning housing 1, and a plug-in hole 12 on one side of the driving cavity 11, which can be used to connect a curtain track; a driving motor 2 is fixed inside the driving cavity 11, and an output shaft 21 is provided on the driving motor 2, and a positioning boss 22 is provided on the outer peripheral side of the driving motor 2.

[0026] A synchronous pulley 3 is fitted onto the drive motor 2, see reference. Figure 2 The synchronous pulley 3 has a recessed cavity 31, and the drive motor 2 is located in the recessed cavity 31. The synchronous pulley 3 and the drive motor 2 are nested together. The synchronous pulley 3 is fixedly connected to the output shaft 21, which drives the synchronous pulley 3 to rotate. A rotating groove 32 is provided below the opening of the recessed cavity 31. The rotating groove 32 is rotatably connected to the positioning boss 22 to ensure the stable operation of the synchronous pulley 3 during rotation. A synchronous belt 33 is fitted on the synchronous pulley 3, and the synchronous belt 33 extends out of the drive cavity 11 through the insertion hole 12. This design nests the drive motor 2 and the synchronous pulley 3 together, simplifying the transmission structure and reducing the overall size of the motor assembly, thereby achieving miniaturization of the curtain motor.

[0027] See Figure 1 , 2The top surface of the clearance cavity 31 is provided with a plug-in shaft 311, and the top end of the output shaft 21 is provided with a transmission hole 211. The plug-in shaft 311 is plugged into and fixed in the transmission hole 211, thereby realizing the transmission effect between the output shaft 21 and the synchronous pulley 3. The cross-section of the plug-in shaft 311 and the transmission hole 211 can be polygonal. Through the orientation effect of the polygon, the plug-in shaft 311 and the transmission hole 211 only need to be plugged in to realize the transmission, which facilitates production assembly and subsequent disassembly.

[0028] See Figure 1 The drive motor 2 is covered with a protective shell 23. In order to reduce the structural damage to the drive motor 2, the fixed connection position between the drive motor 2 and the drive cavity 11 can be set on the protective shell 23. Of course, the fixed connection position can also be set on the drive motor 2. The positioning boss 22 is set on the protective shell 23. The top of the protective shell 23 is provided with a clearance hole 231. The output shaft 21 extends out of the protective shell 23 through the clearance hole 231.

[0029] See Figure 1 , 3 The positioning boss 22 is fitted with a first rotating bearing 24, which is embedded in the rotating groove 32. The first rotating bearing 24 makes the rotation of the synchronous wheel 3 smoother. At the same time, the side wall of the drive cavity 11 is provided with an anti-detachment edge 13. The edge of the synchronous wheel 3 is located above the anti-detachment edge 13. The synchronous wheel 3 and the anti-detachment edge 13 do not directly contact each other. The anti-detachment edge 13 is annular or can be multiple discontinuous arcs. The inner diameter of the anti-detachment edge 13 is similar to the outer diameter of the synchronous wheel 3. The anti-detachment edge 13 can prevent the synchronous wheel 3 from falling off and can also provide a certain orientation effect for the rotating synchronous wheel 3.

[0030] See Figure 1 The synchronous pulley 3 is provided with a connecting boss 34 on its top, and a second rotary bearing 35 is sleeved on the connecting boss 34. The top surface of the drive cavity 11 is provided with an annular support boss 14. In the combined state, the annular support boss 14 abuts against the second rotary bearing 35. The second rotary bearing 35 can prevent the synchronous pulley 3 from directly contacting the top surface of the drive cavity 11, ensuring smooth rotation of the synchronous pulley 3.

[0031] See Figure 1 The positioning housing 1 includes an upper housing 15 and a lower housing 16 that are spliced ​​together. The driving cavity 11 is formed by the upper housing 15 and the lower housing 16 surrounding each other. The anti-detachment edge 13 is provided at the opening of the lower housing 16. The bottom of the lower housing 16 is provided with a detachable sealing cover 161. The driving motor is fixed on the sealing cover 161. The sealing cover can be assembled with the lower housing by means of threaded connection, snap-fit ​​connection, etc. The sealing cover is set to be detachable, which can provide convenience for the replacement and maintenance of the motor in the future.
