[0028] The purpose of this utility model is to provide a curtain electric trolley, curtain track, and curtain trolley track assembly to solve the problems existing in the prior art. It has a simple structure, long service life, and low manufacturing cost.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] As shown in Figures 1-3, this embodiment provides a curtain electric trolley 100, including a drive element 4, a gear transmission assembly, a walking element, a limiting element 2, and a hanging element 1. The power output end of the drive element 4 is connected to the power input end of the gear transmission assembly to realize power input. The power output end of the gear transmission assembly is connected to the walking element, thereby realizing power transmission through the gear transmission assembly to drive the walking element to move. Compared with the traditional belt drive, the curtain electric trolley 100 in this embodiment is simple to assemble, low in cost, and not easily damaged. The walking element is connected to the hanging element 1, and the walking element... Used to move within the curtain track 200, the moving element moves by the friction between itself and the curtain track 200 when it rotates, thereby driving the hanging element 1 to move. The lower end of the hanging element 1 extends out of the curtain track 200 and connects to one side of the upper end of the curtain, so that the curtain can be opened and closed by the hanging element 1. The limiting element 2 is connected to the hanging element 1 and is electrically connected to the driving element 4. The limiting element 2 can control the driving element 4 to stop driving when the hanging element 1 moves into position, so as to ensure that the driving element 4 can stop driving after the curtain is opened or closed in position, thus avoiding damage to the driving element 4.

[0032] As a specific embodiment, the drive element 4 is preferably a worm gear reducer motor. Those skilled in the art may also select other forms of drive element 4 according to actual needs.

[0033] Furthermore, the drive element 4 can also be driven or stopped by receiving radio frequency signals transmitted by the remote control, so as to enable the curtain to perform opening, closing or stopping actions.

[0034] As a specific embodiment, the gear transmission assembly includes a first transmission gear 5 and a second transmission gear 6. The first transmission gear 5 is coaxially connected to the output shaft of the drive element 4, and the outer periphery of the first transmission gear 5 meshes with the outer periphery of the second transmission gear 6. The second transmission gear 6 is coaxially connected to the walking element, and then the drive element 4 drives the first transmission gear 5 to rotate. The first transmission gear 5 drives the second transmission gear 6 to rotate, and the second transmission gear 6 drives the walking element to rotate. By means of the rotation of the walking element and the friction between the walking element and the curtain track 200, the walking function of the walking element is realized.

[0035] In one specific embodiment, the walking element includes a driving wheel 7 and a driven wheel 8. The driving wheel 7 is coaxially connected to the second transmission gear 6 and is connected to one end of the hanging element 1. The driven wheel 8 is connected to the other end of the hanging element 1. The driving wheel 7 acts as a drive wheel, enabling the hanging element 1 to move. Simultaneously, the hanging element 1 drives the driven wheel 8 to move, thus the driven wheel 8 assists in the movement of the hanging element 1, ensuring the stability of the hanging element 1 during movement. Both the driving wheel 7 and the driven wheel 8 are used to contact the curtain track 200. As the driving wheel 7 and the driven wheel 8 rotate on the curtain track 200, they move under the action of friction with the curtain track 200.

[0036] Furthermore, there are two active walking wheels 7 and two driven walking wheels 8. The positions of the two active walking wheels 7 and the two driven walking wheels 8 correspond one-to-one. The two active walking wheels 7 are located on both sides of one end of the hanging element 1, and the two driven walking wheels 8 are located on both sides of the other end of the hanging element 1. That is, the two active walking wheels 7 and the two driven walking wheels 8 are located at the four corners of the hanging element 1, thereby providing stable support for the hanging element 1 and ensuring the smooth and stable movement of the hanging element 1.

[0037] In a preferred embodiment, the two second transmission gears 6 are located on opposite sides of the two first transmission gears 5, thereby shortening the overall length of the curtain electric trolley 100 to a certain extent.

[0038] The limiting element 2 includes two tactile switches, which are respectively installed at both ends of the hanging element 1. The tactile switches are electrically connected to the driving element 4, so that when the hanging element 1 moves into position in the opening direction of the curtain and when it moves into position in the closing direction of the curtain, the tactile switches can be touched and pressed by obstacles on the curtain track 200, so as to control the driving element 4 to stop driving through the tactile switches and avoid damage to the driving element 4.

[0039] As a specific embodiment, when the hanging element 1 moves to fully open the curtain, one of the tactile switches contacts an obstacle on the curtain track 200. At this time, the tactile switch is pressed by the obstacle on the curtain track 200, so as to control the corresponding drive element 4 to stop driving through the tactile switch. When the hanging element 1 moves to fully close the curtain, another tactile switch contacts an obstacle on the curtain track 200. At this time, the tactile switch is pressed by the obstacle on the curtain track 200, so as to control the corresponding drive element 4 to stop driving through the tactile switch.

[0040] In a preferred embodiment, both the tactile switch and the driving element 4 are electrically connected to a motor control board 11. Thus, when the tactile switch is pressed, it can transmit a signal to the motor control board 11 and control the operation of the driving element 4 through the motor control board 11.

[0041] Furthermore, the motor control board 11 can control the drive element 4 to turn on or off by receiving radio frequency signals transmitted by the remote control, so that the user can control and use it.

[0042] In one specific embodiment, the lower end of the hanging element 1 is provided with a hanging ring 3. The hanging ring 3 is used to hang the hook at the upper end of the curtain to achieve a stable connection between the hanging element 1 and the curtain, ensuring that the hanging element 1 can drive the curtain to open and close. In this embodiment, the form of the hanging ring 3 at the lower end of the hanging element 1 and the specific connection method between the hanging ring 3 and the curtain are not specifically limited. Those skilled in the art can choose arbitrarily according to actual needs, as long as a stable connection with the curtain can be achieved and it can be disassembled.

[0043] In a preferred embodiment, the mounting element 1 can be an encapsulated housing, which is disposed inside the curtain track 200. The drive element 4, gear transmission assembly and walking element are all encapsulated inside the encapsulated housing, improving the overall integrity. The lower end of the walking element extends out of the encapsulated housing and its rotation is not affected, ensuring that the walking element can smoothly contact the curtain track 200 and realize the walking function. The limiting element 2 is located outside the encapsulated housing, ensuring that the limiting element 2 can smoothly pass through the curtain track 200 for limiting.

[0044] In this embodiment, in order to facilitate the installation of the drive element 4, the package housing can be designed as a split type. The package side wall 13 of the package housing is connected to the upper cover 14 by a short pin, and the lower cover of the package housing is connected to the end side wall 15 of the package housing by a long pin. A circular hole for the output shaft of the drive element 4 to pass through can be formed between the end side wall 15 and the upper cover 14.

[0045] Example 2

[0046] As shown in Figure 4, this embodiment provides a curtain track 200 for installing the curtain motor trolley 100 in Embodiment 1. It includes a track body 9 and two end caps 10. The track body 9 provides an installation and movement area for the curtain motor trolley 100. The two end caps 10 are respectively encapsulated at both ends of the track body 9, thereby sealing both ends of the track body 9. This improves the overall integrity and also limits the movement of the curtain motor trolley 100. The inner top surface of the track body 9 is provided with positive and negative copper strips 12, preventing the positive and negative copper strips 12 from interfering with the curtain motor trolley. The active and passive wheels 7 and 8 of the 100 series are in contact to avoid affecting the positive and negative copper strips 12, improving stability during use and extending service life. A battery pack is installed inside the end cap 10 to supply power. In this embodiment, the power supply can also be plug-in type. The battery pack is connected to positive and negative electrical connecting pieces, which are electrically connected to the positive and negative copper strips 12 to realize the transmission of power. Through the arrangement of the battery pack, positive and negative electrical connecting pieces, and positive and negative copper strips 12, power is supplied to the drive element 4 to maintain the normal operation of the drive element 4. The track body 9 is preferably a C-shaped track, that is, an elongated hole is formed at the lower end of the track body 9. The lower end of the hanging element 1 can extend to the outside of the track body 9 through the elongated hole. The elongated hole avoids affecting the normal movement of the hanging element 1. At the same time, two walking platforms are formed on both sides of the elongated hole for the walking elements on both sides. That is, there is an active wheel 7 and a passive wheel 8 on each side of the elongated hole. Through the above design, the curtain track 200 in this embodiment can provide a moving platform for the curtain electric trolley 100, and can also avoid affecting the movement of the hanging element 1.

[0047] Specifically, a trolley stopping element is also provided in the middle of the track body 9. The trolley stopping element is an obstacle used to cooperate with the touch switch of the curtain electric trolley 100. Preferably, the trolley stopping element is a limiting plate installed in the track body 9. The two sides of the trolley stopping element are used to limit the two sets of curtain electric trolleys 100 respectively, and the two end caps 10 can be used to limit the two sets of curtain electric trolleys 100 respectively. That is, there are two sets of curtain electric trolleys 100 in the track body 9. The curtain motor trolley 100 is used to drive the opening and closing of two curtains. When one set of curtain motor trolleys 100 drives the corresponding curtain to open, a tactile switch in the curtain motor trolley 100 will contact the end cap 10 on the corresponding side and be pressed, thereby causing the tactile switch to control the corresponding drive element 4 to stop driving. When the curtain motor trolley 100 drives the corresponding curtain to close, another tactile switch in the curtain motor trolley 100 will contact one side of the trolley stop element and be pressed, thereby causing the tactile switch to control the corresponding drive element 4 to stop driving.

[0048] As another implementation method, when there is only one curtain, the curtain electric trolley 100 in the track body 9 is also only set up. In this case, the trolley stopping element does not need to be set up. The limit can be achieved directly by the end caps 10 set at both ends of the track body 9 after the curtain is opened or closed.

[0049] Example 3

[0050] As shown in Figures 4-7, this embodiment provides a curtain trolley track assembly 300, including the curtain electric trolley 100 in Embodiment 1 and at least one curtain track 200 in Embodiment 2. The curtain electric trolley 100 is installed inside the curtain track 200. In this embodiment, the number of curtain tracks 200 inside the curtain electric trolley 100 is not specifically limited. Those skilled in the art can make adaptive adjustments according to the actual number of curtain panels, so that one curtain corresponds to one curtain electric trolley 100, so that each curtain is controlled by an individual curtain electric trolley 100 to achieve individual opening and closing.
