Description

Technical Field

[0001] This utility model relates to the field of curtain machine technology, and in particular to a positioning 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] When the curtain track is uneven or affected by external vibrations, the moving body may bounce or undulate when moving on the curtain track, resulting in unstable movement and noise during the movement. Utility Model Content

[0004] In view of this, the present invention proposes a positioning mechanism for a curtain machine, the purpose of which is to achieve longitudinal positioning of the moving body on the curtain guide rail and improve the movement stability of the moving body.

[0005] The solution provided by this utility model includes:

[0006] A positioning mechanism for a curtain machine, the positioning mechanism being disposed on a movable body on a curtain track, the positioning mechanism comprising:

[0007] The hanging part is a roller rotatably mounted on the movable body and is hung on the curtain track;

[0008] Two sets of longitudinal pressure rollers are disposed on the movable body and configured to abut against the curtain rail upward under the action of elastic force; the two sets of longitudinal pressure rollers are positioned at a height difference with the position of the hanging part, and the two sets of longitudinal pressure rollers are located in front of and behind the hanging part in the length direction of the main body of the rail, so that the hanging part and the two sets of longitudinal pressure rollers are distributed in a triangular position.

[0009] As a further alternative, the longitudinal pressure roller is rotatably mounted on a wheel frame, the wheel frame is slidably mounted vertically on the moving body, and the moving body is also provided with an elastic element for driving the wheel frame to move upward.

[0010] As a further alternative, the elastic element is a spring.

[0011] As a further alternative, the longitudinal pressure roller abuts against the bottom of the curtain track.

[0012] As a further optional solution, the longitudinal pressure roller is a rubber roller.

[0013] As a further alternative, two sets of longitudinal pressure rollers are symmetrically arranged in front of and behind the suspension.

[0014] Compared with the prior art, the positioning mechanism for curtain machines in this application has at least the following advantages:

[0015] The suspension section provides primary support and guidance, while two sets of longitudinal pressure rollers, through elasticity, firmly press against the curtain track, limiting the vertical swaying of the moving part. This significantly enhances the stability of the moving part on the curtain track, ensuring smooth and stable operation and reliable curtain opening and closing. The smoother movement of the moving part on the curtain track reduces collisions and friction between components caused by bouncing and undulation. The more orderly relative movement between components avoids abnormal noise caused by unstable movement. This creates a quiet and comfortable user environment, especially suitable for noise-sensitive spaces such as bedrooms and studies, enhancing the user experience. Attached Figure Description

[0030] refer to Figures 1 to 6 An embodiment of this utility model shows a positioning mechanism 5 for a curtain machine, wherein the positioning mechanism 5 is disposed on a movable body 2 on a curtain guide rail 1;

[0031] The curtain track 1 includes a track body 11, on which a conductive strip 13 and a transmission belt 12 extending along its length are provided; a movable body 2 is slidably disposed along the track body 11; the movable body 2 is provided with a conductive contact 22 and a transmission wheel 21, the transmission wheel 21 meshing with the transmission belt 12, and the conductive contact 22 contacting and conducting electricity with the conductive strip 13; 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, which is a motor, and 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 track 1; the driver 3 forms an electrical connection with the conductive strip 13 through the conductive contact 22; the cooperation principle and materials of the conductive contact 22 and the conductive strip 13 can be referred to the patent application information with application number 202423057746.4.

[0032] refer to Figure 4 The positioning mechanism 5 includes a suspension part 24 and two sets of longitudinal pressure rollers 51. The suspension part 24 is a roller rotatably mounted on the movable body 2 and is hung on the curtain rail 1. The longitudinal pressure rollers 51 are mounted on the movable body 2 and are configured to abut against the curtain rail 1 upward under the action of elastic force. The two sets of longitudinal pressure rollers 51 are positioned at a height difference from the suspension part 24, and the two sets of longitudinal pressure rollers 51 are located in front of and behind the suspension part 24 in the length direction of the rail body 11, so that the suspension part 24 and the two sets of longitudinal pressure rollers 51 are distributed in a triangular position.

[0033] Specifically, the movable body 2 is suspended on the guide rail body 11 of the curtain rail 1 via the suspension part 24. The suspension part 24 uses rollers, which reduces the frictional resistance between the movable body 2 and the guide rail body 11, resulting in smoother movement. Furthermore, two sets of longitudinal pressure rollers 51 firmly press against the curtain rail 1 through elastic force, effectively clamping the curtain rail 1 longitudinally with the suspension part 24. This restricts the up-and-down swaying of the movable body 2, greatly enhancing its stability on the curtain rail 1 and ensuring smooth and stable operation, thus guaranteeing the reliability of the curtain opening and closing operation. Because the movement of the movable body 2 on the curtain rail 1 is more stable, collisions and friction between components caused by bouncing and undulation are reduced.

[0034] In some embodiments, such as Figures 4 to 6 As shown, the longitudinal pressure roller 51 is rotatably mounted on a wheel frame 53, the wheel frame 53 is slidably mounted on the moving body 2 along the vertical direction, and the moving body 2 is also provided with an elastic element 52 for driving the wheel frame 53 to move upward.

[0035] In this embodiment, by setting the wheel frame 53, the longitudinal pressure roller 51 is rotatable and movable, so that the longitudinal pressure roller 51 rolls against the curtain rail 1, reducing frictional resistance; and the longitudinal pressure roller 51 is elastically pressed against the curtain rail 1, thereby clamping the curtain rail 1.

[0036] Specifically, in the above scheme, the elastic element 52 is a spring; a spring is a common and low-cost elastic element that is readily available on the market. Using a spring as the elastic element 52 can reduce the manufacturing cost of the positioning mechanism 5, while also facilitating procurement and assembly during the production process and improving production efficiency. Of course, in other embodiments, the elastic element 52 can also be a spring sheet, tension spring, or other parts with elastic force, capable of applying an upward driving force to the wheel frame 53.

[0037] Specifically, in the above scheme, the longitudinal pressure roller 51 abuts against the bottom of the curtain track 1. When the longitudinal pressure roller 51 abuts against the bottom of the curtain track 1, the friction between it and the curtain track 1 can provide a certain lateral restraint force.

[0038] Specifically, in the above scheme, the longitudinal pressure roller 51 is a rubber roller. Rubber rollers have good elasticity and cushioning properties. When the longitudinal pressure roller 51 contacts the curtain track 1, the rubber roller can absorb some vibration and impact, reducing noise and component wear caused by unevenness of the curtain track 1 or external vibration. At the same time, it can also alleviate the bumpy feeling during the movement of the movable body 2 to a certain extent, making the opening and closing of the curtains more stable and quiet.

[0039] Specifically, in the above scheme, two sets of longitudinal pressure rollers 51 are symmetrically arranged in front of and behind the suspension part 24. The symmetrical arrangement of the two sets of longitudinal pressure rollers 51 in front of and behind the suspension part 24 can make the constraint force on the moving body 2 on the curtain rail 1 more uniform and balanced.

[0040] In summary, this application provides a positioning mechanism 5 for a curtain machine. The hanging part 24 provides primary support and guidance, while the two sets of longitudinal pressure rollers 51, through elastic force, firmly press against the curtain rail 1, limiting the up-and-down swaying of the moving body 2. This significantly enhances the stability of the moving body 2 on the curtain rail 1, enabling it to operate smoothly and reliably, ensuring the reliability of the curtain opening and closing operation. Because the movement of the moving body 2 on the curtain rail 1 is more stable, collisions and friction between components caused by bouncing and undulation are reduced. The relative movement between components is more orderly, avoiding abnormal noise caused by unstable movement. This creates a quiet and comfortable user environment, especially suitable for noise-sensitive places such as bedrooms and studies, improving the user experience.

[0041] 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 in other embodiments.

[0042] 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.
