The first part 301 and the second part 302 are communicated with each other. The first part 301 of the first shell 300 is a driving box, and the second part 302 of the first shell 300 and the second shell 400 are transmission boxes.

[0036] The driving part 200 comprises a first driving mechanism 1 and a second driving mechanism 2, preferably, both of the driving mechanisms are tubular motors, and the axial directions of the two tubular motors are parallel to each other and are parallel to the length direction of the track 100.

[0037] The transmission part comprises a driving transmission mechanism and a driven transmission mechanism, the driving transmission mechanism is mainly arranged in the second part 302 of the first shell 300, and comprises a first transmission shaft 31, a second transmission shaft 32, a third transmission shaft 33, a fourth transmission shaft 34, a third bevel gear 35, a fourth bevel gear 36, a fifth bevel gear 37 and a sixth bevel gear 38. The axial directions of the first transmission shaft 31, the second transmission shaft 32 and the third transmission shaft 33 are perpendicular to the axial directions of the driving mechanisms, and the axial direction of the fourth transmission shaft 34 is parallel to the axial directions of the driving mechanisms.

[0038] The third bevel gear 35 is fixedly arranged on the outer periphery of the first transmission shaft 31, so that the third bevel gear 35 and the first transmission shaft 31 are coaxial and can rotate synchronously. The first bevel gear 11 on the first driving mechanism 1 is engaged with the third bevel gear 35, so that the first transmission shaft 31 can be driven to rotate around its own axis.

[0039] The second transmission shaft 32 and the third transmission shaft 33 are coaxially arranged and synchronously rotate, and can be integrally formed or connected by a split structure (such as a key groove to enable synchronous rotation).

[0040] The arrangement of the above-mentioned driving part 200 (the first driving mechanism 1 and the second driving mechanism 2 arranged side by side) and the driving mechanism (each transmission shaft and bevel gear) reduces the size of the driving device located at the end of the track 100, which refers to the length in the length direction of the track 100, that is, the size in the left-right direction as shown in FIG. 1, and reduces the occupied space. Figure 3

[0041] The driving mechanism further includes a driving gear 39 fixedly arranged on the outer periphery of the first transmission shaft 31, so that the two synchronously rotate. The driven transmission mechanism further includes a synchronous belt 41 and a driven gear 42. The second housing 400 is provided with a support seat 401, and the driven gear 42 is rotatably supported on the support seat 401. The rotation axes of the driven gear 42 and the driving gear 39 (that is, the axial direction of the first transmission shaft 31) are parallel to each other, and both extend in the front-rear direction (that is, the width direction of the track 100) in the normal installation state and are located on the same horizontal plane. The synchronous belt 41 is annular and is wound around the driving gear 39 and the driven gear 42. Thus, the synchronous belt 41 is in a vertical installation form (rotated by 90° relative to the prior art), part of which is located between the top portions of the driving gear 39 and the driven gear 42, and part of which is located between the bottom portions of the driving gear 39 and the driven gear 42. The synchronous belt 41 meshes with the driving gear 39 and the driven gear 42, respectively, so that the driving gear 39 and the driven gear 42 can rotate clockwise or counterclockwise as shown in FIG. 1. Figure 3

[0042] ​​The motorized vertical blind further comprises a light adjusting shaft 500 and a plurality of carriages 600, one of the carriages 600 is fixedly connected with the synchronous belt 41, and the blind sheet (not shown) of the vertical blind is fixedly connected with the carriage 600, so that the carriage 600 is translated during the rotation of the synchronous belt 41, and the blind sheet of the vertical blind is driven to open and close. The light adjusting shaft 500 is coaxially arranged and fixed with the fourth transmission shaft 34, so that the light adjusting shaft 500 and the fourth transmission shaft 34 can synchronously rotate, the light adjusting shaft 500 is used for adjusting the rotation angle of the blind sheet, the light adjusting shaft 500 passes through the carriages 600 and enters into the second housing 400, and is rotatably supported in the second housing 400. The connection mode of the synchronous belt 41, the carriage 600 and the light adjusting shaft 500 with the blind sheet is the same as that of the prior art, and will not be described here.

[0043] Referring to Figs. 1 and 2 again, Figure 2 and Figure 3 The carriage 600 is partially arranged in the track 100 and partially arranged below the track 100. The synchronous belt 41 and the carriage 600 are arranged in parallel and spaced apart along the width direction of the track 100 (the front-rear direction in the normal installation state, that is, the axial direction of the first transmission shaft 31). Compared with the prior art in which the synchronous belt 41 is horizontally arranged above the carriage 600, the present application can reduce the overall height of the track 100 in the up-down direction. At least one of the carriages 600 is connected with the synchronous belt 41 through a connecting seat 601, and the connecting seat 601 is located between the carriage 600 and the synchronous belt 41, so that the connecting seat 601 is translated along with the rotation of the synchronous belt 41. The track 100 is provided with a guide 101 in the form of a horizontally arranged T-shaped head (that is, the head is a stroke extending upward and downward at this time), and the guide 101 enters into the connecting seat 601, so that the connecting seat 601 can move along the guide 101, and the T-shaped head limits the position of the connecting seat 601 along the width direction of the track 100 and limits the up-down position of the connecting seat 601, so that the connecting seat 601 can only move along the length direction of the track 100.

[0044] The position, at which the carriage 600 is arranged to pass out of the bottom of the track 100, forms an opening 102, and the track 100 is provided with a gasket 103 on the inner side of the opening 102, which is attached to the corresponding position of the carriage 600, so as to reduce the friction and noise. The gasket 103 can be a plastic gasket.
