[0029] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] The present invention proposes a straight curtain motor, the combination of the motor and the track body 4 is as follows Figure 1 As shown, the motor includes a protective housing 1, a power cavity 11 is provided in the protective housing 1, and an opening is provided on the side wall of the power cavity 11;

[0032] See Figure 2 、 5 A drive motor 2 is placed horizontally in the power chamber 11. The drive motor 2 is provided with an output shaft 21. The output shaft 21 is located on the lower side of 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 、 5, a transmission mechanism 3 is provided on one side of the drive motor 2, and the transmission mechanism 3 is also located in the power cavity 11. The drive motor 2 and the transmission mechanism 3 are in a vertical relationship. The transmission mechanism 3 includes a positioning shell 31, a synchronous wheel 32 and a transmission wheel 33. The positioning shell 31 is fixedly connected to the power cavity 11, and a synchronous belt 34 is sleeved on the synchronous wheel 32. A first give way groove 311 is provided at the bottom of the positioning shell 31, and a second give way groove 321 is provided at the bottom of the synchronous wheel 32. The transmission wheel 33 is rotatably connected to the first give way groove 311, and the positioning shell 31 extends into the second give way groove 321. The synchronous wheel 32 is rotatably connected to the positioning shell 31. A clutch is provided between the transmission wheel 33 and the synchronous wheel 32. The transmission wheel 33 meshes with the driving gear 22, and 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 the drive motor 2 and the transmission mechanism 3 is as follows: when the drive motor 2 is used as the power output source, the clutch controls the transmission wheel 33 and the synchronous wheel 32 to achieve synchronous rotation, and the drive gear 22 on the drive motor 2 engages with the transmission wheel 33, thereby driving the rotation of the synchronous wheel 32, and then the synchronous belt 34 is driven by the synchronous wheel 32 to control the opening and closing of the curtains; when the drive motor 2 is powered off, the clutch releases the synchronization effect, the transmission wheel 33 engages with the drive gear 22 and remains stationary, and the synchronous wheel 32 can rotate freely. At this time, the user can open and close the curtains by manually pulling them.

[0035] See Figure 5 In this product, the drive motor 2 is placed horizontally, and the synchronous wheel 32, the positioning shell 31 and the transmission wheel 33 are nested layer by layer. The drive motor 2 adopts an off-axis motor, which can increase the overlapping space 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, so that the overall height of the power output part can 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 and inward-opening windows in actual applications, ensuring the safety of the drive motor 2, and at the same time making the overall appearance of the electric curtain smoother, improving its overall aesthetics, thereby 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 an iron core is provided at the center of the clutch seat 35. 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. A rotating groove 322 is provided on the top surface of the second give way groove 321. The clutch seat 35 is rotatably connected to the rotating groove 322. Two positioning grooves 323 are provided on the side walls of the rotating groove 322. When the drive motor 2 is not powered, the magnetic beads 36 are adsorbed on both sides of the elliptical minor axis of the clutch seat 35 by the magnetic effect, and the magnetic beads 36 do not contact the synchronous wheel 32, and the synchronous wheel 32 can rotate freely. At this time, the clutch does not have a synchronization effect; when the drive motor 2 is powered, the drive motor drives the transmission wheel 33 to rotate, and then the transmission wheel 33 drives the clutch seat 35 to rotate synchronously. Under the action of centrifugal force, the two magnetic beads 36 move toward the opposite sides along the curved surface of the clutch seat 35 until the magnetic beads 36 on both sides are respectively stuck between the clutch seat 35 and the positioning groove 323. The specific state is as follows Figure 4 As shown, at this time, the clutch seat 35 can drive the synchronous wheel 32 to rotate, that is, the clutch produces a synchronization effect.

[0037] See Figure 3 A rotating boss 324 is provided on the top surface of the second give way groove 321, and the rotating boss 324 is preferably provided at the center. A rotating groove 351 is provided on the clutch seat 35. Through the rotational cooperation between the rotating boss 324 and the rotating groove 351, friction between the clutch seat 35 and the side of the second give way groove 321 is avoided, thereby 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 walls of the rotating groove 322. When the clutch is in effect, the two magnetic beads 36 can be located at the two end sides of the clutch seat to achieve the transmission effect of the clutch seat 35 and the synchronous wheel 32.

[0039] See Figure 3 、 6 The clutch seat 35 is provided with a connecting column 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 column 352 passes through the through hole 312 and is fixed in the connecting groove 331, thereby realizing a 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 a linkage opening 313 is provided on the side of the positioning shell 31. The driving gear 22 is arranged in the linkage opening 313. The linkage opening 313 is used to further reduce the total height occupied by the driving motor 2 and the transmission mechanism 3, thereby making the thickness of the power part as close to the track body 4 as possible to improve the overall flatness of the product.

[0041] See Figure 2 、 3 The top surface of the synchronous wheel 32 is provided with a first clamping boss 325, and the bottom surface of the transmission wheel 33 is provided with a second clamping boss 332. The first clamping boss 325 is clamped with a first bearing 326, and the second clamping boss 332 is clamped with a second bearing 333. The upper and lower surfaces of the power chamber 11 are respectively provided with an upper clamping groove 111 and a lower clamping groove 112. The first bearing 326 is clamped in the upper clamping groove 111, and the second bearing 333 is clamped in the lower clamping groove 112. The rotation effect of the transmission wheel 33 and the synchronous wheel 32 is achieved through the setting of the bearings.

[0042] See Figure 2 、 3 A positioning groove 314 is provided on the top surface of the first give way groove 311, 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 give way groove 311, thereby extending the service life of the transmission wheel 33.

[0043] See Figure 3 The protective shell 1 includes an upper shell 12 and a lower shell 13 spliced ​​together. A maintenance port 131 is provided on the bottom surface of the lower shell 13. A removable sealing plate 132 is provided in the maintenance port 131. The drive motor 2 is located above the sealing plate 132. When the drive motor 2 needs to be repaired, 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 subsequent maintenance.

[0044] Referring to FIG. 2 , a plurality of synchronous teeth 327 are provided on the circumferential side surface of the synchronous wheel 32, an anti-slip edge 328 is provided on the lower edge of the synchronous wheel 32, and an engaging tooth groove is provided on the synchronous belt 34. The engaging tooth groove engages with the synchronous teeth 327 to realize transmission. During use, the anti-slip edge 328 can prevent the synchronous belt 34 from falling off the synchronous wheel 32, thereby ensuring the stability of the synchronous transmission effect.
