[0028] The purpose of the present invention is to provide an electric curtain pulley, a curtain track and a curtain pulley track group to solve the problems existing in the prior art, with simple structure, long service life and low manufacturing cost.

[0029] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Embodiment 1

[0031] As Figures 1 - 3 shown, this embodiment provides an electric curtain pulley 100, including a driving element 4, a gear transmission assembly, a running element, a limiting element 2 and a hanging element 1. The power output end of the driving element 4 is connected to the power input end of the gear transmission assembly to achieve power input. The power output end of the gear transmission assembly is connected to the running element, and then the power is transmitted through the gear transmission assembly to drive the running element to run. Compared with the traditional belt drive, the electric curtain pulley 100 in this embodiment is simple to assemble, low in cost and not easily damaged. The running element is connected to the hanging element 1, and the running element is used to run in the curtain track 200. The running of the running element is realized by the friction force between the running element and the curtain track 200 when the running element rotates, and then the hanging element 1 is driven to move. The lower end of the hanging element 1 is used to extend out of the curtain track 200 and connect to one side of the upper end of the curtain to drive the curtain to open and close through the hanging element 1. The limiting element 2 is connected to the hanging element 1, the limiting element 2 is electrically connected to the driving element 4, and the limiting element 2 can control the driving element 4 to stop driving when the hanging element 1 moves in place, so as to ensure that the driving element 4 can stop driving after the curtain opens and closes in place, avoiding damage to the driving element 4.

[0032] As a specific embodiment, the driving element 4 is preferably a worm and gear reduction motor, and those skilled in the art can also select other forms of driving elements 4 according to actual needs.

[0033] Further, the driving element 4 can also be driven or stopped by receiving the radio frequency signal transmitted by the remote control, so as to drive the traction curtain to perform an opening action, a closing action or a stopping action.

[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 driving element 4. 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. Then, by driving the driving element 4 to rotate the first transmission gear 5, 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. Through the rotation of the walking element and by means of the friction force between the walking element and the curtain track 200, the walking function of the walking element is realized.

[0035] As a specific embodiment, the walking element includes a driving walking wheel 7 and a driven walking wheel 8. The driving walking wheel 7 is coaxially connected to the second transmission gear 6, and the driving walking wheel 7 is connected to one end of the hanging element 1. The driven walking wheel 8 is connected to the other end of the hanging element 1. The driving walking wheel 7 serves as a driving wheel and can drive the hanging element 1 to move. At the same time, the hanging element 1 drives the driven walking wheel 8 to walk. Then, the driven walking wheel 8 assists the movement of the hanging element 1 to ensure the stability of the hanging element 1 during the movement process. Both the driving walking wheel 7 and the driven walking wheel 8 are used to contact the curtain track 200. Then, as the driving walking wheel 7 and the driven walking wheel 8 rotate on the curtain track 200, the driving walking wheel 7 and the driven walking wheel 8 realize walking under the action of the friction force with the curtain track 200.

[0036] Further, there are two driving walking wheels 7 and two driven walking wheels 8 respectively. The two driving walking wheels 7 and the two driven walking wheels 8 are in one-to-one correspondence in position, and the two driving walking wheels 7 are respectively located on both sides of one end of the hanging element 1, and the two driven walking wheels 8 are respectively located on both sides of the other end of the hanging element 1. That is, the two driving walking wheels 7 and the two driven walking wheels 8 are respectively located at the four corners of the hanging element 1, so as to provide stable support for the hanging element 1 and ensure the smooth and stable movement of the hanging element 1.

[0037] As a preferred embodiment, the two second transmission gears 6 are respectively located on the side where the two first transmission gears 5 are far away from each other, so as to shorten 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. Thus, after the hanging element 1 moves in place in the curtain opening direction and in the curtain closing direction, 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, avoiding 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, this tactile switch is pressed by the obstacle on the curtain track 200, so as to control the corresponding driving element 4 to stop driving through this tactile switch. When the hanging element 1 moves to fully close the curtain, the other tactile switch contacts an obstacle on the curtain track 200. At this time, this tactile switch is pressed by the obstacle on the curtain track 200, so as to control the corresponding driving element 4 to stop driving through this tactile switch.

[0040] As 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 action of the driving element 4 through the motor control board 11.

[0041] Furthermore, the motor control board 11 can control the driving element 4 to turn on or off by receiving the radio frequency signal emitted by the remote control, so as to facilitate the user to control and use.

[0042] As a specific embodiment, a hanging ring 3 is provided at the lower end of the hanging element 1. The hanging ring 3 is used to hang the hook at the upper end of the curtain, so as to realize the stable connection between the hanging element 1 and the curtain and ensure 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, and those skilled in the art can arbitrarily select them according to actual needs, as long as the stable connection with the curtain can be realized and it can be disassembled.

[0043] As a preferred embodiment, the hanging element 1 can be a sealed housing, and the sealed housing is arranged inside the curtain track 200. Thus, the driving element 4, the gear transmission assembly and the walking element are all encapsulated inside the sealed housing, improving the integrity. And the lower end of the walking element extends out of the sealed housing and the rotation is not affected, ensuring that the walking element can smoothly contact the curtain track 200 and realize the walking function, while the limiting element 2 is located outside the sealed housing, ensuring that the limiting element 2 can be smoothly limited by the curtain track 200.

[0044] In this embodiment, for the convenience of installing the driving element 4, the encapsulation housing can adopt a split design. The encapsulation side wall 13 of the encapsulation housing is connected to the upper cover 14 through short pins, and the lower cover of the encapsulation housing is connected to the end side wall 15 of the encapsulation housing through long pins. A circular hole for the output shaft of the driving element 4 to pass through can be formed by buckling between the end side wall 15 and the upper cover 14.

[0045] Embodiment 2

[0046] As Figure 4 shown, this embodiment provides a curtain track 200 for installing the curtain electric pulley 100 in Embodiment 1, including a track body 9 and two end closures 10. The track body 9 is used to provide an installation and movement area for the curtain electric pulley 100. The two end closures 10 are respectively encapsulated at both ends of the track body 9, thereby realizing the sealing of both ends of the track body 9, which can not only improve the integrity but also play a role in limiting the curtain electric pulley 100. The inner top surface of the track body 9 is provided with positive and negative copper strips 12, so that the positive and negative copper strips 12 do not contact the driving wheels 7 and the driven wheels 8 of the curtain electric pulley 100, avoiding affecting the positive and negative copper strips 12, improving the stability during use, and at the same time extending the service life. A battery pack is installed in the end closure 10, and the battery pack is used to supply electric energy. In this embodiment, plug-in power supply can also be selected for the provision of electric energy. The battery pack is connected with positive and negative electrical connection pieces, and the positive and negative electrical connection pieces are electrically connected to the positive and negative copper strips 12 to realize the transmission of electric energy. Thus, through the settings of the battery pack, the positive and negative electrical connection pieces, and the positive and negative copper strips 12, power is supplied to the driving element 4 to maintain the normal operation of the driving element 4. The track body 9 is preferably a C-shaped track, that is, a long strip hole is formed at the lower end of the track body 9, and the lower end of the hanging element 1 can extend out of the track body 9 through the long strip hole. Thus, through the setting of the long strip hole, the normal movement of the hanging element 1 is not affected. At the same time, two walking platforms are formed on both sides of the long strip hole, which are respectively used for the walking of the walking elements on both sides, that is, a driving wheel 7 and a driven wheel 8 are correspondingly arranged on both sides of the long strip hole. Through the above design, the curtain track 200 in this embodiment can not only provide a moving platform for the curtain electric pulley 100 but also avoid affecting the movement of the hanging element 1.

[0047] Specifically, a trolley stopping element is further provided in the middle of the track body 9. The trolley stopping element is an obstacle for cooperating with the touch switch of the curtain electric trolley 100. The trolley stopping element is preferably a limiting plate installed in the track body 9. The two sides of the trolley stopping element are respectively used to limit the two groups of curtain electric trolleys 100, and the two end closures 10 can respectively be used to limit the two groups of curtain electric trolleys 100. That is, two groups of curtain electric trolleys 100 are provided in the track body 9, and the two groups of curtain electric trolleys 100 are respectively used to drive the opening and closing of two curtains. When one group of curtain electric trolleys 100 drives the corresponding curtain to open in place, a touch switch in the curtain electric trolley 100 will contact the end closure 10 on the corresponding side and be pressed, thereby causing the touch switch to control the corresponding driving element 4 to stop driving. When the curtain electric trolley 100 drives the corresponding curtain to close in place, another touch switch in the curtain electric trolley 100 will contact one side of the trolley stopping element and be pressed, thereby causing the touch switch to control the corresponding driving element 4 to stop driving.

[0048] As another implementation manner, when only one curtain is provided, only one group of curtain electric trolleys 100 is provided in the track body 9. At this time, the trolley stopping element may not be provided, and the end closures 10 provided at both ends of the track body 9 can directly achieve the limit after the curtain is opened or closed in place.

[0049] Embodiment III

[0050] As Figures 4 - 7 shown, this embodiment provides a curtain trolley track group 300, which includes the curtain electric trolley 100 in Embodiment I and at least one curtain track 200 in Embodiment II, and the curtain electric trolley 100 is installed in the curtain track 200. In this embodiment, the number of curtain tracks 200 in the curtain electric trolley 100 is not specifically limited, and those skilled in the art can make adaptive adjustments according to the actual number of curtain sheets, and make one curtain correspond to one curtain electric trolley 100, so that each curtain is controlled by a separate curtain electric trolley 100 to achieve independent opening and closing.

[0051] Specific examples are used in the present invention to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation of the present invention.
