[0035] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0036] As an embodiment of the present application, Figures 1 to 8 As shown, a vertical curtain track assembly is disclosed, comprising: a guide rail 600 for hanging curtains, a main transmission box 100 disposed at one end of the guide rail 600, and a motor 200 connected to the main transmission box 100. The motor 200 provides power to the guide rail 600 for opening and closing the curtains, and the main transmission box 100 transmits the power generated by the motor 200 to the guide rail 600. The main transmission box 100 and the motor 200 are detachably connected.

[0037] Vertical curtains are a type of automatic curtains, commonly known as dream curtains, and are a new type of curtain. The most common types of automatic curtains are vertical roller blinds, left and right opening and closing curtains, and horizontal Venetian blinds. The present application is for vertical curtains, and the way they change from light transmission to light blocking is similar to that of ordinary horizontal Venetian blinds, but each blind is vertically set and hung on a guide rail, and the angle of each blind is adjusted by a motor to achieve light blocking and light transmission. At the same time, the present application is for a vertical curtain with a gauze curtain on the blinds, so that the curtain can be adjusted between full light blocking and semi-light blocking, so it is commonly known as a dream curtain.

[0038] Vertical curtains operate differently from standard electric curtains. Their motor and track are inseparable. The motor is a key component of automated curtains and is also the most prone to failure. Currently, the motor and track are inseparable. When a motor malfunctions and requires repair or replacement, the entire vertical curtain track must be disassembled to remove the motor for repair or replacement.

[0039] The main transmission case 100 of the present application is connected to the motor 200 via a detachable connection. The motor 200 is a single unit. If the motor 200 malfunctions and requires repair or replacement, the entire automatic curtain track does not need to be disassembled, making it very convenient to remove the motor 200 for repair or replacement. On the other hand, if the motor 200 and curtain track were integrated, the opening, closing, and dimming of the automatic curtains would have to be performed separately. However, with the motor 200 now being a single unit, simultaneous operations are possible. Furthermore, the motor 200 is compact and can be packaged separately, making it less susceptible to damage.

[0040] Specifically, the main transmission box 100 includes a box housing 110 and a driving gear 120. The driving gear 120 is arranged in the box housing 110 to transmit the power generated by the motor 200. The motor 200 includes a motor housing 210, a connector 220 and a motor 240; the connector 220 is connected to the transmission shaft 241 of the motor 240; the end of the connector 220 away from the transmission shaft 241 of the motor 240 is engaged with the end of the driving gear 120 close to the motor 200; the motor housing 210 is fixedly connected to the box housing 110 by a detachable connection. It should be noted that, if Figure 4 and Figure 5 As shown in the example, the embedding described here refers to a connection method in which the protruding structure of one side is inserted into the groove structure of the other side, and the protruding structure of the other side is inserted into the groove structure of one side, and the two sides are in mutual embedding contact.

[0041] The specific method for fixing the motor housing 210 to the box housing 110 through a detachable connection method can be that the motor housing 210 and the box housing 110 are connected through a threaded connection. Specifically, after the track assembly is installed on the wall, threaded holes are set on the ground surfaces of the motor housing 210 and the box housing 110, and then the motor 200 is fixed to the main transmission box 100 with screws to ensure that the motor 200 is fixed.

[0042] In this solution, when the motor 200 needs to be removed, the fixed connection between the motor housing 210 and the box housing 110 is first separated. Because the end of the connector 220 away from the transmission shaft 241 of the motor 240 is engaged with the end of the driving gear 120 close to the motor 200, the motor 200 can then be directly removed without disassembling the entire automatic curtain track. The connection method in which the end of the connector 220 away from the transmission shaft 241 of the motor 240 is engaged with the end of the driving gear 120 close to the motor 200 not only facilitates the removal of the motor 200, but also ensures that the motor 240 can normally drive the driving gear 120.

[0043] The motor 200 also includes a spring 300. The motor housing 210 includes a main body 211 and a cover head 212 connected to the main body; the cover head 212 is close to the main transmission case 100, while the main body 211 is away from the main transmission case 100. The cover head 212 is provided with a receiving cavity 212a, and a first boss 212b is provided at one end of the receiving cavity 212a near the main transmission case 100.

[0044] The connector 220 includes a mating portion 221 that is embedded in the driving gear 120, a connector body 222 that is connected to the mating portion 221, and a second boss 223 that is arranged on the connector body 222 and within the accommodating cavity 212a; the connector body 222 is provided with a mating cavity 222a that is mated with the transmission shaft 241 of the motor 240.

[0045] The motor 240 is disposed within the main body 211, and the transmission shaft 241 of the motor 240 extends from the main body 211 into the accommodating cavity 212a. The connector body 222 is disposed within the accommodating cavity 212a, and the transmission shaft 241 of the motor 240 is inserted into the mating cavity 222a. The connector 220 can move relative to the transmission shaft 241 in the axial direction and be fixed relative to the transmission shaft 241 in the radial direction. Specifically, the transmission shaft 241 can be configured as a polygonal prism, and the mating cavity 222a can be configured to correspond to the shape of the transmission shaft 241. The spring 300 is disposed within the accommodating cavity 212a and is sleeved on the connector body 222, located between the second boss 223 and the bottom of the accommodating cavity 212a.

[0046] The spring 300 pushes the connector 220 toward the main transmission box 100, the first boss 212b clamps the second boss 223, and the mating portion 221 extends out of the accommodating cavity 212a; after the mating portion 221 is subjected to pressure in the direction of the motor 240, it is compressed in the accommodating cavity 212a.

[0047] This solution realizes the elastic connection between the connector 220 and the transmission shaft 241 of the motor 240 through the above-mentioned specific structure. When the motor 200 is installed in position, the matching portion 221 is not required to be completely engaged with the end of the driving gear 120 close to the motor 200 during installation. For example, if the two are not completely engaged, the matching portion 221 will be temporarily compressed within the accommodating cavity 212a after being subjected to pressure in the direction of the motor 240. At this time, the motor 200 can also be installed normally. After the motor 200 is installed, as soon as it is started, the matching portion 221 rotates, and at the same time, under the elastic force of the spring 300, it automatically fully engages with the end of the driving gear 120 close to the motor 200, thereby driving the driving gear 120 to rotate normally. When disassembly is required, after loosening the motor housing 210 and the box housing 110, the motor 200 can be directly removed without disassembling the entire automatic curtain track.

[0048] A third boss 212 c is further provided on the inner surface of the accommodating cavity 212 a . When the matching portion 221 is compressed in the accommodating cavity 212 a , the third boss 212 c clamps the second boss 223 to limit the displacement of the connector 220 .

[0049] Specifically, the mating portion 221 is a fourth boss 221a disposed at intervals, which is a bump. Correspondingly, the end of the driving gear 120 near the motor 200 is provided with a fifth boss 121 disposed at intervals, which is a bump. The fourth boss 221a and the fifth boss 121 can be interlocked. The cross-sections of the fourth boss 221a and the fifth boss 121 can be sector-shaped.

[0050] The fourth boss 221a and the fifth boss 121 may also be loosely fitted. The gap between the fourth boss 221a and the fifth boss 121 can provide a buffer space and prevent the fourth boss 221a and the fifth boss 121 from getting stuck with each other, which would affect the disassembly of the motor 200. Specifically, there are two fourth bosses 221a and five bosses 121, and the central angle between each fourth boss 221a and the fifth boss is 80°. After the fourth boss 221a and the fifth boss 121 are engaged, a gap will exist between the fourth boss 221a and the fifth boss 121.

[0051] The height of the fourth boss 221a and the fifth boss 121 is 3 mm.

[0052] The cover head 212 is provided with an alignment portion 230, which is arranged on the outer side of the accommodating cavity 212a near one end of the main transmission case 100. Correspondingly, the case housing 110 is provided with an alignment groove 111 that cooperates with the alignment portion 230. The alignment portion 230 and the alignment groove 111 facilitate the alignment of the motor 200 with the main transmission case 100, thereby facilitating installation of the motor 200.

[0053] The track assembly also includes a dimming motor 400, which is arranged in the main transmission box 100 and is used to adjust the inclination angle of the curtain venetian blinds. At present, the opening and closing and dimming of automatic curtains share a motor 200, and the clutch switches between opening and closing and dimming to achieve the opening and closing or dimming function. With such a design of automatic curtains, because they share a motor 200, opening and closing and dimming must be performed separately. Dimming cannot be performed at the same time when opening and closing, and opening and closing cannot be performed at the same time when dimming. This solution sets a dimming motor 400 to control the curtain venetian blinds separately, so that opening and closing and dimming can be achieved.

[0054] The track assembly also includes a secondary transmission box 500, which is arranged on the end of the guide rail 600 opposite to the main transmission box 100; the secondary transmission box 500 cooperates with the main transmission box 100 to transmit the power generated by the motor 200 to the guide rail 600, thereby ensuring the transmission effect of the automatic curtain.

[0055] The above content is a further detailed description of the present application in conjunction with specific optional implementation methods, and the specific implementation of the present application cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, they can make several simple deductions or substitutions without departing from the concept of the present application, which should be considered to fall within the scope of protection of the present application.
