Description

Technical Field

[0001] This utility model relates to the field of curtain track technology, specifically to an electric Roman rod curtain track. Background Technology

[0002] A Roman rod is a horizontal rod used to hang curtains. The rod is cylindrical, about four centimeters in diameter, and its length depends on the size of the window. The two ends of the rod are gourd-shaped capitals, which serve a decorative purpose. It is named for its resemblance to the style of ancient Roman architecture.

[0003] Electric blinds are blinds that open and close by using a motor to drive pulleys. Electric blinds are usually used in conjunction with Roman rods, but Roman rods still have some problems during use:

[0004] 1. Currently, when designing an electric curtain system based on a Roman rod, in order to achieve automatic opening and closing of the curtains, in addition to the track and motor, a control device is also required.

[0005] 2. Currently, when designing curtain tracks, end caps are designed at both ends of the track to enable the transmission components to convert power. The end caps are generally designed with a large space, which increases the installation space of the entire curtain track and also increases the weight.

[0006] 3. In existing curtain tracks, the trolleys used to move the curtains when they are open are obstructed by the curtains, causing their sliding parts to become misaligned within the track. This prevents the trolleys from sliding smoothly in a straight line within the track, resulting in unstable movement of the curtains. Utility Model Content

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] (1) By setting up a Duya motor, the present invention not only has the characteristics of high efficiency and low noise, but also supports a variety of intelligent control methods, including remote control by mobile phone APP, voice assistant operation, etc., so that the electric curtain system designed on the basis of Roman rod can realize the automatic opening and closing of the curtain without adding a control device.

[0027] (2) By setting up a main and auxiliary transmission box, the main transmission box is provided with a first support seat for supporting the active gear and an active wheel that is sleeved with the active gear. The shaft of the Duya motor drives the active gear to rotate through the active wheel. At the same time, the first box of the main transmission box is provided with a first arc-shaped channel for the active gear to drive the belt to move. This allows the rotational motion of the Duya motor shaft to be converted into linear motion within the limited space of the main transmission box, thereby driving the opening and closing of the curtain. Moreover, this design can ensure that the curtain remains stable during the opening and closing process, reduce the vibration and wear that may be caused by direct drive, and thus extend the service life of the curtain.

[0028] (3) This utility model uses a Duya motor to drive the active gear to rotate, and with the assistance of the driven gear, the belt moves back and forth in the track housing. The first straight section of the belt drives the first trolley to move back and forth, and the second straight section drives the second trolley to move back and forth. The first trolley and the second trolley move in opposite directions, so that the second trolley, driven indirectly by the drive motor, drives the left curtain to move to the left or right, and the first trolley drives the right curtain to move to the right or left, thereby achieving the opening and closing of the curtains at the same speed and with the same stroke. Moreover, by lengthening the trolley, the connecting arm pulls two sliding blocks to move, and the two sliding blocks are movably connected by the connecting rod. When the curtain is opened, the curtain on the connecting plate is blocked by the other curtains, and the sliding block connected to the connecting arm is also blocked and tilted. This prevents it from sliding normally in a straight line in the sliding channel, while the other sliding block can still pull the trolley to slide in a straight line in the sliding channel, so that the entire trolley can move smoothly and quickly in a straight line, thereby making the entire curtain move stably.

The base plate 103 has a sliding channel 12, and the pulley sliding cavity 10 is connected to the lower long groove 7 through the sliding channel 12. The belt 203 includes a first straight section 2031 and a second straight section 2032 located at the front and rear, and a curved section 2 connecting the two ends of the first straight section 2031 and the second straight section 2032. 033, the curved sections 2033 at both ends are respectively fitted onto the driving gear 201 and the driven gear 202; the main transmission box 4 includes a first box body 401 set on the top of the Duya motor 204, and a first support seat 402 for supporting the driving gear 201 is set inside the first box body 401. A first circular hole is opened in the middle of the first support seat 402, and a first lower bushing 403 is connected to the bottom of the first circular hole. The driving gear 201 is connected to the lower side of the driving bushing 2011. The driving bushing 2011 passes through the first circular hole and is fitted onto the first lower bushing 403. A driving wheel 205 with the same central axis as the first lower bushing 403 is set at the top of the middle of the first support seat 402. The driving gear 201 is fitted onto the driving wheel 205. The top of the shaft of the Duya motor 204 is successively... The drive shaft sleeve 2011 and the first circular hole pass through the drive wheel 205 and are sleeved on the drive wheel 205; the auxiliary transmission box 5 includes a second box body 501 and a second cover plate 502 for sealing the second box body 501. The second box body 501 is provided with a second support seat 503 for supporting the driven gear 202. The second support seat 503 has a second circular hole in the middle. The bottom of the second circular hole is connected to a second lower shaft sleeve 504. The driven gear 202 is connected to the lower side of the driven shaft sleeve 2021. The driven shaft sleeve 2021 passes through the second circular hole to the second lower shaft sleeve 504 and is sleeved on the second lower shaft sleeve 504. The top of the second support seat 503 is provided with a driven wheel 206 with the same central axis as the second lower shaft sleeve 504. The driven gear 202 is sleeved on the driven wheel 206.The trolley structure 3 includes a first trolley 13 and a second trolley 14. The first trolley 13 is disposed on the first straight section 2031, and the second trolley 14 is disposed on the second straight section 2032. Both the first trolley 13 and the second trolley 14 include a sliding part slidably connected to the track housing 101, a mounting part installed on the belt 203 and connected to the sliding part, and a connecting part extending out of the track housing 101.

The other sliding block 301 still pulls the trolley to slide linearly on the sliding channel 12, thus preventing the entire trolley from deviating from its original track, allowing the entire trolley to move smoothly and quickly in a straight line, thereby stabilizing the movement of the entire curtain.

[0044] In this embodiment, as Figure 7 As shown, the inner side of the top wall of the first housing 401 is connected to a first upper bushing 4011, a first arc-shaped plate 4012, a pair of parallel first straight plates 4013 connected to the first arc-shaped plate 4012, and a first frame plate 4014. The first upper bushing 4011 is sleeved between the shaft of the Duya motor 204 and the drive wheel 205. A first opening 4015 for the belt 203 to pass through is opened on the inner wall of the first housing 401 on the side connected to the track 1. The first straight plate 4013 is away from the first arc-shaped plate. One end of 4012 and one end of the first frame plate 4014 are both connected to the inner wall with the first opening 4015. A first arc-shaped channel 15 is provided between the first arc plate 4012 and the drive wheel 205 for the drive gear 201 to drive the belt 203 to move. A first straight channel 16 is provided between the first straight plate 4013 and the first frame plate 4014 for the belt 203 to move. One end of the first straight channel 16 is connected to the first arc channel 15, and the other end is connected to the first opening 4015.

[0045] Specifically, under the rotation of the shaft of the Duya motor 204, the drive wheel 205 drives the drive gear 201 to rotate, and the rotation of the drive gear 201 drives the belt 203 to move. The belt 203, which enters the first housing 401 from the track 1 through the first opening 4015, passes through a first straight channel 16, a first arc channel 15 and another first straight channel 16, and then returns to the track 1 through the first opening 4015.

[0046] In this embodiment, as Figure 1 and Figure 7 As shown, the top of the first housing 401 is provided with a first hollow column 4016 for mounting the first upper bushing 4011, and the first hollow column 4016 extends to the surface of the first housing 401. The first arc plate 4012, the first straight plate 4013 and the first frame plate 4014 all extend to the surface of the first housing 401. This top design of the first housing 401 corresponds to its internal design, making the main transmission box 4 compact and space-saving.

[0047] In this embodiment, as Figure 6 As shown, the inner side of the top wall of the second housing 501 is connected to a second upper bushing 5011, a second arc-shaped plate 5012, a pair of parallel second straight plates 5013 connected to the second arc-shaped plate 5012, and a second frame plate 5014. The driven wheel 206 is fitted onto the second upper bushing 5011. A second opening 5015 for the belt 203 to pass through is provided on the inner wall of the side of the second housing 501 connected to the track 1. The end of the second straight plate 5013 away from the second arc-shaped plate 5012 is... One end of the second frame plate 5014 is connected to the inner wall with the second opening 5015. A second arc-shaped channel 17 is provided between the second arc plate 5012 and the driven wheel 206 for the driven gear 202 to drive the belt 203 to move.

One end of the second straight channel 18 is connected to the second arc channel 17, and the other end is connected to the second opening 5015.

[0048] Specifically, under the action of the driving gear 201 driving the driven gear 202 to rotate through the belt 203, the belt 203 entering the second housing 501 from the track 1 through the second port 5015 passes through a second straight channel 18, a second arc channel 17 and another second straight channel 18, and then returns to the track 1 through the second port 5015.

[0049] In this embodiment, as Figure 1 and Figure 6As shown, the top of the second housing 501 is provided with a second hollow column 5016 for mounting the second upper bushing 5011, and the second hollow column 5016 extends to the surface of the second housing 501. The second arc plate 5012, the second straight plate 5013 and the second frame plate 5014 all extend to the surface of the second housing 501. This top design of the second housing 501 corresponds to its internal design, making the auxiliary transmission box 5 compact and space-saving.

[0050] In this embodiment, as Figure 1 and Figure 2 As shown, decorative heads 19 are connected to the ends of the main transmission box 4 and the auxiliary transmission box 5 that are away from the track housing 101.

[0051] In this embodiment, as Figure 4 As shown, the connecting arm 304 includes a connecting section 3041 and an extension section 3042. The connecting arm 304 is mounted on the bottom side of the sliding block 301 by bolts 305 and clamping plate 306. The extension section 3042 has a first mounting hole 3043 for mounting the curtain.

[0052] In this embodiment, as Figure 2 As shown, the connecting part of the first trolley 13 extends to the outside of the second straight segment 2032, and the connecting part of the second trolley 14 extends to the outside of the first straight segment 2031, so that the sliding edges of the curtains on the left and right sides can be folded back and forth to better block sunlight.

[0053] In this embodiment, as Figure 1 and Figure 2 As shown, universal alloy wheels 20 and several nano silent wheels 21 are slidably connected to the track housing 101 on both sides of the first trolley 13 and the second trolley 14. The universal alloy wheels 20 and nano silent wheels 21 are slidably connected in the pulley sliding cavity. Limiting plates 22 are fixedly connected to both ends of the track housing 101. A first mounting plate 23 for installing curtains is connected under the limiting plate 22.

[0054] Specifically, the universal alloy wheel 20 allows the edge of the curtain to move in multiple directions; the nano silent wheel 21 reduces noise when the curtain rollers move within the track 1; the limiting plate 22 prevents the rollers on the track 1 from moving; and the first mounting plate 23 is used to fix the edge of the curtain to the stationary side.

[0055] In this embodiment, as Figure 2As shown, several second mounting plates 24 are also snapped into the upper long groove 6. The second mounting plates 24 have second mounting holes (not marked in the figure). The top of the track housing 101 is provided with the same number of mounting rods 9 as the second mounting plates 24. The bottom of the mounting rods 9 has mounting grooves corresponding to the track housing 101 (not marked in the figure), and the mounting rods 9 have third mounting holes (not marked in the figure) that communicate with the mounting grooves. The track housing 101 is installed at the bottom of the mounting rods 9 by screws passing through the third mounting hole, the mounting groove and the second mounting hole in sequence.

[0056] Before use, the operator first installs the mounting rod 9 on the top of the track housing 101, and then installs the mounting rod 9 on the wall above the window, so that the electric track 1 is installed above the window. During use, the operator powers on the Duya motor 204, and then inputs commands via a mobile app or speaks commands through the voice assistant function. The Duya motor 204 rotates the shaft forward and backward according to the commands. The forward and reverse rotation of the shaft drives the drive gear 201 to rotate forward and backward via the drive wheel 205. With the assistance of the driven gear 202, the belt 20... 3. The belt 203 moves back and forth within track 1. The first straight section 2031 of the belt 203 drives the first trolley 13 to move back and forth, and the second straight section 2032 drives the second trolley 14 to move back and forth.
