[0003] In current motorized curtains, the motor is usually installed perpendicular to the curtain track, and the motor protrudes significantly from the track. This protruding part of the motor may interfere with the use of other furniture. For example, if there is a balcony cabinet on the balcony, the motor at the end of the curtain track is very close to the cabinet door. When the cabinet door is opened, it is very likely to hit the motor, causing damage. At the same time, the protruding part of the motor greatly affects the aesthetics of the curtain track. Therefore, how to improve the overall flatness of the motor and the curtain track is an urgent problem to be solved. Utility Model Content

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] 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.

[0031] This utility model proposes a flat curtain motor, the combination state of the motor and the track body 4 is as follows: Figure 1 As shown, the motor includes a protective housing 1, and a power chamber 11 is provided inside the protective housing 1. The power chamber 11 has an opening on its side wall.

[0032] See Figure 2 , 5 A drive motor 2 is horizontally placed inside the power chamber 11. The drive motor 2 is provided with an output shaft 21. The output shaft 21 is located below the axis of the drive motor 2. This type of motor is commonly known as an off-axis motor. A drive gear 22 is provided on the output shaft 21.

[0033] See Figure 3 , 5The drive motor 2 is provided with a transmission mechanism 3 on one side, which is also located in the power cavity 11. The drive motor 2 and the transmission mechanism 3 are perpendicular to each other. The transmission mechanism 3 includes a positioning shell 31, a synchronous pulley 32 and a transmission wheel 33. The positioning shell 31 is fixedly connected to the power cavity 11. A synchronous belt 34 is sleeved on the synchronous pulley 32. The bottom of the positioning shell 31 is provided with a first clearance groove 311 and the bottom of the synchronous pulley 32 is provided with a second clearance groove 321. The transmission wheel 33 is rotatably connected to the first clearance groove 311. The positioning shell 31 extends into the second clearance groove 321. The synchronous pulley 32 is rotatably connected to the positioning shell 31. A clutch is provided between the transmission wheel 33 and the synchronous pulley 32. The transmission wheel 33 meshes with the drive gear 22. The synchronous belt 34 extends out of the protective shell 1 through the opening and then extends into the track body.

[0034] The transmission principle of drive motor 2 and transmission mechanism 3 is as follows: When drive motor 2 is the power output source, the clutch controls the transmission wheel 33 and the synchronous wheel 32 to rotate synchronously. The drive gear 22 on drive motor 2 meshes with the transmission wheel 33, thereby driving the synchronous wheel 32 to rotate. Then, the synchronous wheel 32 drives the synchronous belt 34 to control the opening and closing of the curtain. When drive motor 2 is de-energized, the clutch releases the synchronization effect, the transmission wheel 33 meshes with the drive gear 22 and remains stationary, and the synchronous wheel 32 can rotate freely. At this time, the user can manually pull the curtain to open and close it.

[0035] See Figure 5 This product features a horizontally positioned drive motor 2, with the synchronous pulley 32, positioning housing 31, and transmission pulley 33 nested in layers. The drive motor 2 is an off-axis motor, which increases the overlap in height between the drive motor 2 and the transmission mechanism 3, thereby reducing the longitudinal space required after the drive motor 2 and the transmission mechanism 3 are combined. This allows the overall height of the power output section to be basically flush with the track body 4, effectively reducing the probability of interference between the drive motor 2 and other furniture with cabinet doors or inward-opening windows in practical applications, ensuring the safety of the drive motor 2, and making the overall appearance of the electric curtains smoother and improving its overall aesthetics, thus promoting the market promotion of electric curtains.

[0036] See Figure 2The clutch includes a clutch seat 35 and two magnetic beads 36. The clutch seat 35 is elliptical and has an iron core at its center. The magnetic beads 36 are located on both sides of the clutch seat 35. The clutch seat 35 is fixedly connected to the transmission wheel 33. The top surface of the second clearance groove 321 is provided with a rotating groove 322. The clutch seat 35 is rotatably connected in the rotating groove 322. The side wall of the rotating groove 322 is provided with two positioning grooves 323. When the drive motor 2 is not powered, the magnetic beads 36 are magnetically attracted to both sides of the elliptical minor axis of the clutch seat 35. The magnetic beads 36 are not in contact with the synchronous pulley 32, which can rotate freely. At this time, the clutch does not have a synchronizing effect. When the drive motor 2 is powered, the drive motor drives the transmission wheel 33 to rotate, which in turn drives the clutch seat 35 to rotate synchronously. Under the action of centrifugal force, the two magnetic beads 36 move along the arc surface of the clutch seat 35 to opposite sides until the magnetic beads 36 on both sides are respectively stuck between the clutch seat 35 and the positioning groove 323, as shown in the specific state. Figure 4 As shown, at this time, the clutch seat 35 can drive the synchronous pulley 32 to rotate, that is, the clutch produces a synchronizing effect.

[0037] See Figure 3 The second clearance groove 321 has a rotating boss 324 on its top surface. The rotating boss 324 is preferably located at the center. The clutch seat 35 has a rotating groove 351. Through the rotational engagement of the rotating boss 324 and the rotating groove 351, friction between the clutch seat 35 and the side of the second clearance groove 321 is avoided, thus ensuring the safe operation of the transmission mechanism.

[0038] See Figure 2 , 4 The positioning groove 323 is arc-shaped, and the two positioning grooves 323 are symmetrically arranged on the side wall of the rotating groove 322. When the clutch is activated, the two magnetic beads 36 can be locked at both ends of the clutch seat to achieve the transmission effect between the clutch seat 35 and the synchronous pulley 32.

[0039] See Figure 3 , 6 The clutch seat 35 is provided with a connecting post 352, the positioning shell 31 is provided with a through hole 312, and the transmission wheel 33 is provided with a connecting groove 331. The connecting post 352 passes through the through hole 312 and is inserted and fixed in the connecting groove 331, thereby realizing the fixed connection between the clutch seat 35 and the transmission wheel 33.

[0040] See Figure 3 , 5The transmission wheel 33 is a face gear, and the side of the positioning shell 31 is provided with a linkage port 313. The drive gear 22 is located in the linkage port 313. The linkage port 313 is used to further reduce the total height occupied by the drive motor 2 and the transmission mechanism 3, so that the thickness of the power part is as close as possible to the track body 4, thereby improving the overall flatness of the product.

[0041] See Figure 2 , 3 The top surface of the synchronous pulley 32 is provided with a first engaging boss 325, and the bottom surface of the transmission pulley 33 is provided with a second engaging boss 332. A first bearing 326 is engaged on the first engaging boss 325, and a second bearing 333 is engaged on the second engaging boss 332. The upper and lower surfaces of the power cavity 11 are respectively provided with an upper engaging groove 111 and a lower engaging groove 112. The first bearing 326 is engaged in the upper engaging groove 111, and the second bearing 333 is engaged in the lower engaging groove 112. The rotation effect of the transmission pulley 33 and the synchronous pulley 32 is achieved through the arrangement of the bearings.

[0042] See Figure 2 , 3 The top surface of the first clearance groove 311 is provided with a positioning groove 314, and an annular gasket 37 is provided in the positioning groove 314. The annular gasket 37 is coaxially arranged with the through hole 312. The annular gasket 37 can prevent the transmission wheel 33 from directly rubbing against the top surface of the first clearance groove 311, thereby extending the service life of the transmission wheel 33.

[0043] See Figure 3 The protective housing 1 includes an upper housing 12 and a lower housing 13 that are spliced ​​together. The bottom surface of the lower housing 13 is provided with a maintenance port 131. A removable sealing plate 132 is provided inside the maintenance port 131. The drive motor 2 is located above the sealing plate 132. When the drive motor 2 needs maintenance, the user only needs to remove the sealing plate 132 to take the drive motor 2 out of the power chamber 11, which provides convenience for later maintenance.

[0044] Referring to Figure 2, the synchronous pulley 32 has a plurality of synchronous teeth 327 on its circumferential side surface, and an anti-detachment edge 328 is provided on the lower edge of the synchronous pulley 32. The synchronous belt 34 has a meshing groove, which meshes with the synchronous teeth 327 to achieve transmission. During use, the anti-detachment edge 328 can prevent the synchronous belt 34 from falling off the synchronous pulley 32, so as to ensure the stability of the synchronous transmission effect.

[0045] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
