Abstract
Description
Technical Field
[0001] This utility model relates to the field of curtain machine technology, and in particular to a self-adjusting mechanism for curtain machines. Background Technology
[0002] An electric curtain motor is a device that enables curtains to open and close automatically. Currently, one type of transmission method for electric curtain motors on the market, as shown in patent documents such as CN201263033Y (publication number CN201263033Y) or 202423057746.4, involves two conductive strips and a rack within the curtain track. A movable body is also arranged within the curtain track. This movable body is equipped with brushes, a drive wheel, and a motor that drives the gears. The brushes conduct electricity in contact with the conductive strips, and the drive wheel on the movable body meshes with the rack on the curtain track. When the motor drives the gears to rotate, the gears move the movable body within the curtain track. By passing electricity of different polarities through the two conductive strips, the forward and reverse rotation of the motor can be controlled, and the movement of the movable body enables the curtains to open and close.
[0003] However, when this transmission structure is applied to curved tracks, the moving body cannot adapt to the bending changes on the curved track, resulting in it being unable to move smoothly and getting stuck on the curtain track, thus making it impossible to achieve the curved track configuration. Utility Model Content
[0004] In view of this, the present invention proposes a self-adjusting mechanism for curtain machines, which aims to solve the problem that the moving body in the curtain machine cannot adapt to the bending changes of the curtain track.
[0005] The solution provided by this utility model includes:
[0006] A self-adjusting mechanism for a curtain machine, the curtain machine including a curtain rail and a movable body slidably disposed on the curtain rail, the self-adjusting mechanism being disposed on the movable body, the self-adjusting mechanism including two sets of elastic side pressure components distributed on both sides of the curtain rail;
[0007] The elastic side-pressure assembly includes a first side-pressure roller and a second side-pressure roller. The first side-pressure roller and the second side-pressure roller are spaced apart along the length of the curtain rail. Both the first side-pressure roller and the second side-pressure roller are configured to abut against the side of the curtain rail under the action of elastic force. The forces exerted by the two sets of elastic side-pressure assemblies on the side of the curtain rail are opposite.
[0008] As a further optional solution, the elastic side-pressure assembly is disposed outside the curtain rail, with the first side-pressure roller and the second side-pressure roller abutting against the outer surface of the curtain rail.
[0009] As a further optional solution, the elastic side-pressure assembly is disposed inside the curtain track, with the first side-pressure roller and the second side-pressure roller abutting against the inner side of the curtain track.
[0010] As a further optional solution, the elastic side-pressure assembly also includes a swing arm and a first elastic element;
[0011] The swing arm has two arms, which correspond to the first side pressure wheel and the second side pressure wheel respectively; the first end of the swing arm is hinged to the moving body around a vertical pivot, and the second end of the swing arm is rotatably connected to the first side pressure wheel / second side pressure wheel.
[0012] The first elastic element causes the swing arm to swing about its first end.
[0013] As a further alternative, the first elastic element is a tension spring, with two swing arms connected to its two ends to bring the two swing arms closer together.
[0014] As a further alternative, the first elastic element is a spring, and there are four first elastic elements, which correspond to two first side pressure rollers and two second side pressure rollers respectively.
[0015] As a further alternative, the first elastic element is a torsion spring, which acts on the first end of the swing arm to cause the first end of the swing arm to rotate about the vertical axis.
[0016] Compared with the prior art, the self-adjusting mechanism for curtain machines in this application has at least the following advantages:
[0017] By incorporating two sets of elastic side-pressure components distributed on both sides of the curtain track on the moving body, when running on curved tracks, the first and second side-pressure rollers in each set are tightly pressed against the side of the curtain track due to elastic force. As the moving body approaches a curve, the contact state between the side-pressure rollers and the side of the curtain track dynamically changes according to the curvature of the track. This change guides the moving body's direction of movement to automatically adapt to the curvature of the track, achieving a self-adjusting function. This ensures that the moving body can smoothly and easily pass through curved tracks, effectively avoiding the problem of traditional structures easily getting stuck on curved tracks, and greatly expanding the application possibilities of electric curtain motors in complex track environments.
[0018] Furthermore, the two sets of elastic side pressure components exert opposite forces on the sides of the curtain track, enabling the moving body to maintain a stable posture when moving on the curtain track, reducing swaying and deviation during movement, and improving the smoothness and reliability of the curtain machine operation.

Example 1
[0036] refer to Figure 1 and Figure 2 An embodiment of this utility model shows a self-adjusting mechanism for a curtain machine, wherein the self-adjusting mechanism 4 is disposed on a movable body 2 on a curtain guide rail 1.
[0037] The curtain track 1 includes a track body 11. The track body 11 has conductive strips 13 and transmission belts 12 extending along its length on both sides. In this embodiment, the conductive strips 13 and transmission belts 12 are arranged opposite to each other. The movable body 2 is slidably disposed along the guide rail body 11; the movable body 2 is provided with a conductive contact 22 and a transmission wheel 21, the transmission wheel 21 is located on one side of the guide rail body 11 and meshes with the transmission belt 12, the conductive contact 22 is in contact with the conductive strip 13 and conducts electricity; the conductive contact 22 is configured to be held against the conductive strip 13 by elastic force; the movable body 2 is provided with a driver 3, the driver 3 is a motor, the driver 3 drives the transmission wheel 21 on the movable body 2 to rotate, thereby realizing the movement of the movable body 2 on the curtain guide rail 1, the driver 3 forms an electrical connection with the conductive strip 13 through the conductive contact 22; for the cooperation method and materials of the conductive contact 22 and the conductive strip 13, please refer to the patent information with application number 202423057746.4.
[0038] refer to Figure 3 and Figure 4 The self-adjusting mechanism 4 includes two sets of elastic side-pressure components 41 distributed on both sides of the curtain rail 1. Each elastic side-pressure component 41 includes a first side-pressure roller 411 and a second side-pressure roller 412, which are spaced apart along the length of the curtain rail 1. Both the first and second side-pressure rollers are configured to abut against the side of the curtain rail 1 under elastic force. The forces exerted by the two sets of elastic side-pressure components 41 on the side of the curtain rail 1 are opposite. In this embodiment, the elastic side-pressure components 41 are located outside the curtain rail 1, and the first and second side-pressure rollers 411 and 412 abut against the outer surface of the curtain rail 1.
[0039] Specifically, the elastic side pressure assembly 41 further includes a swing arm 413 and a first elastic element 414; the swing arm 413 is provided with two arms, which correspond to the first side pressure wheel 411 and the second side pressure wheel 412 respectively; the first end of the swing arm 413 is hinged to the moving body 2 around a vertical pivot 415, and the second end of the swing arm 413 is rotatably connected to the first side pressure wheel 411 / the second side pressure wheel 412; the first elastic element 414 causes the swing arm 413 to swing around its first end.
[0040] The first side pressure wheel 411 and the second side pressure wheel 412 in the elastic side pressure assembly 41 are symmetrically arranged front and back along the length of the curtain rail 1. In the initial state, the two sets of elastic side pressure assemblies 41 are symmetrical on both sides of the rail body 11. The initial state is when the two elastic side pressure assemblies 41 are subjected to the same force.
[0041] like Figure 5 As shown, when the moving body 2 is located on the straight section of the curtain rail 1, the two elastic side pressure components 41 are symmetrical from left to right, and the first side pressure wheel 411 and the second side pressure wheel 412 in one elastic side pressure component 41 are symmetrical from front to back.
[0042] like Figure 6 As shown, when the moving body 2 is located on the curved section of the curtain track 1, the first side pressure roller 411 and the second side pressure roller 412 in each set of elastic side pressure components 41 are tightly pressed against the side of the curtain track 1 by the elastic force, so that the moving direction of the moving body 2 automatically adapts to the curvature of the curved track, realizing the self-adjustment function. Furthermore, in this embodiment, the two sets of elastic side pressure components 41 are clamped on both sides of the curtain track 1, so that the moving body 2 can maintain a stable posture when moving on the curtain track 1, reducing swaying and deviation during movement, and improving the smoothness and reliability of the curtain machine operation.
[0043] There are multiple implementation methods for the first elastic element 414 to drive the first side pressure roller 411 and the second side pressure roller 412 to press against the side of the curtain rail 1:
[0044] For example, see Figure 3 or Figure 5 The first elastic element 414 is a tension spring, and the two ends of the tension spring are respectively connected to two swing arms 413 to make the two swing arms 413 move closer to each other. In this embodiment, only one first elastic element 414 needs to be provided in an elastic side pressure assembly 41, and the first side pressure wheel 411 and the second side pressure wheel 412 can be subjected to the same elastic action, thereby improving their symmetry.
[0045] For example, see Figure 7 The first elastic element 414 is a spring, and there are four first elastic elements 414, which correspond to two first side pressure rollers 411 and two second side pressure rollers 412 respectively. In this embodiment, the two first side pressure rollers 411 and the two second side pressure rollers 412 are driven by independent first elastic elements 414, which provides strong independence.
[0046] For example (not shown in this embodiment), the first elastic element 414 is a torsion spring, which acts on the first end of the swing arm 413 to make the first end of the swing arm 413 rotate around the vertical axis 415.
[0047] In addition, the first elastic element 414 can also be a spring sheet or other structure with elastic function, which will not be listed here. Example 2
[0048] refer to Figure 8 and Figure 9The second embodiment is basically the same as the first embodiment, except that the self-adjusting mechanism 4 in the second embodiment is set inside the curtain track 1.
[0049] The curtain track 1 also includes a track body 11, a conductive strip 13 and a drive belt 12, but the conductive strip 13 and the drive belt 12 are arranged on two opposite inner sides inside the track body 11;
[0050] The movable body 2 (not shown in Embodiment 2) is provided with transmission wheels 21 and conductive contact parts 22 on both sides; the transmission and cooperation principle between the movable body 2 and the curtain rail 1 is the same as that in Embodiment 1, only the positions are different.
[0051] In this embodiment, two sets of elastic side-pressure components 41 are respectively disposed on both sides of the movable body 2. The elastic side-pressure components 41 are disposed inside the curtain rail 1, and the first side-pressure wheel 411 and the second side-pressure wheel 412 abut against the inner side of the curtain rail 1.
[0052] It should be noted that in this embodiment, if the curtain track 1 is a curved track, the width of the internal space of the curtain track 1 can be larger than the designed width of the movable body 2, so that the movable body 2 can have enough space to swing inside the curtain track 1 to adapt to the curvature of the curved track. Naturally, the greater the curvature of the curtain track 1, the greater the space provided for the movable body 2 to swing should be; this can be set according to actual needs.
[0053] In summary, this application provides a self-adjusting mechanism 4 for a curtain motor. This mechanism 4 comprises two sets of elastic side-pressure components 41 distributed on both sides of the curtain rail 1 on the moving body 2. When running on a curved track, the first side-pressure roller 411 and the second side-pressure roller 412 in each set of elastic side-pressure components 41 are tightly pressed against the side of the curtain rail 1 by elastic force. When the moving body 2 reaches a bend, the contact state between the side-pressure rollers and the side of the curtain rail 1 dynamically changes according to the degree of curvature of the track. This change guides the moving body 2 to automatically adapt to the curvature of the track, achieving a self-adjusting function. This ensures that the moving body 2 can smoothly and easily pass through the curved track, effectively avoiding the problem of traditional structures easily getting stuck on curved tracks, and greatly expanding the application possibilities of electric curtain motors in complex track environments.
[0054] Furthermore, the two sets of elastic side pressure components 41 exert opposite forces on the side of the curtain rail 1, which enables the moving body 2 to maintain a stable posture when moving on the curtain rail 1, reducing swaying and deviation during movement, and improving the smoothness and reliability of the curtain machine operation.
[0055] It should be noted that the self-adjusting mechanism 4 is not necessarily used on curved tracks; it can also be applied to straight tracks, at least improving the smoothness of the movement of the moving body 2 on the curtain track 1.
[0056] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
