A first chamber 11 for accommodating a belt and a second chamber 12 provided below the first chamber 11 for accommodating a boom and a hanger wheel body are formed in a space formed by the two side portions 13 and the top portion 14, and the first chamber 11 and the second chamber 12 both extend in the length direction of the rail 1. The up-and-down arrangement structure of the first chamber 11 and the second chamber 12 enables the whole width of the electric curtain rail to be narrowed, and the electric curtain rail is suitable for places with narrow installation environments.

A partition board 111 is longitudinally arranged in the first chamber 11 along the length direction of the track 1, the partition board 111 divides the first chamber 11 into a third chamber 112 and a fourth chamber 113 for the belt to penetrate through, the third chamber 112 and the fourth chamber 113 are respectively communicated with the second chamber 12, and an opening 121 is formed in the bottom of the second chamber 12.

Referring to fig. 3, the motorized window treatment track further includes a mounting assembly 2, the mounting assembly 2 includes a connecting portion 21 capable of butting two adjacent tracks 1, and a top-mounting portion 22 capable of fixing the butted tracks 1 to an external mounting base (e.g., a ceiling), and the connecting portion 21 and the top-mounting portion 22 are an integrally formed structure. The integral forming structure of the connecting part 21 and the top mounting part 22 not only reduces the number of accessories, but also reduces the installation steps of the electric curtain rail, and can also increase the matching coaxiality between the rails 1, thereby reducing the noise when the electric curtain is used.

Referring to fig. 4, the outer side of each side portion 13 of the rail 1 is provided with a first catching groove 133 longitudinally arranged in the length direction of the rail 1, the first catching groove 133 being formed by the outer side surface of the side portion 13 being inwardly recessed. The connecting portion 21 includes a first engaging portion 211 that engages with the first card slot 133. The top 14 of the rail 1 is provided with a second catching groove 141 arranged laterally in the length direction of the rail 1, the second catching groove 141 being formed by a top surface of the top 14 being depressed downward. The connecting portion 21 further includes a second engaging portion 214 engaged with the second card slot 141. Through the cooperation between connecting portion 21 and first draw-in groove 133, the second draw-in groove 141 for in track 1 can insert installation component 2, and accurate completion butt joint in installation component 2 reduces because of the produced step phenomenon of butt joint between two tracks 1. Each of the first engaging portions 211 extends in the longitudinal direction, the second engaging portion 214 is located between the tops of the two first engaging portions 211, and the second engaging portion 214 extends in the lateral direction.

The two top-mounting portions 22 extend laterally from the junction between the second engaging portion 214 and the first engaging portion 211 in a direction away from the second engaging portion 214.

The upper end of the side portion 13 of the rail 1, the side far away from the first cavity 11, is bent downward to form a first bent portion 131, and the connecting portion 21 has a first bayonet 212 adapted to the first bent portion 131. The lower end of the side portion 13, which is away from the second chamber 12, is bent upward for a certain distance and then bent toward the second chamber 12, thereby forming a hook-shaped second bent portion 132. The connecting portion 21 has a second bayonet 213 adapted to the second bent portion 132. The two ends of the top 14 of the rail 1 corresponding to each top-mounted portion 22 and the side far away from the first cavity 11 are respectively bent and extended towards the middle to form a third bending portion 142, and a third bayonet 215 adapted to the third bending portion 142 is formed between the second engaging portion 214 and the top-mounted portion 22.

The first engaging portion 211 has a side positioning hole 2111, and the second engaging portion 214 has an upper positioning hole 2141. After the two rails 1 are inserted into the mounting assembly 2, fasteners, such as bolts, are inserted through the side positioning holes 2111 and the upper positioning holes 2141 of the mounting assembly 2 to abut against the side portions 13 and the top portion 14 of the rails 1, respectively, thereby completing the butt fastening of the two rails 1.

When the bolts abut against the side portions 13 and the top portion 14 of the rail 1, a force toward the inside of the rail 1 is generated from the two side portions 13 and the top portion 14, so that the first bent portion 131 and the first bayonet 212, the second bent portion 132 and the second bayonet 213, and the third bent portion 142 and the third bayonet 215 are fitted more closely, the rail 1 is further shaped by the connecting portion 21, and the coaxiality of the butted rail 1 is improved. The step error generated after the adjacent two rails 1 are connected due to the deformation of the side parts 13 and the top part 14 is reduced, and the noise generated by the translation of the curtain roller in the rail 1 is reduced, so that the electric curtain rail is more silent.

After the rail 1 is butted by the mounting component, the whole electric curtain rail is finally fixed on the mounting position through the top mounting hole 221 arranged on the top mounting part 22.
