Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shading, in particular to an opening and closing curtain, and more particularly to a dual-motor direct-drive power device. Background Art
[0002] The existing curtain powertrain is driven by a single motor, and the clutch assembly is provided with two independent clutch structures, which can realize the movement of the transmission belts of the two tracks to realize the opening and closing movement of the curtain. Although this design realizes the intelligent control of the curtain to a certain extent, there are still some technical problems and challenges.
[0003] The single motor mechanism makes the structure of the clutch assembly complicated, which may affect the reliability and maintainability of the entire system. The complex structure may lead to an increase in production costs and make subsequent maintenance more difficult. Since the clutch assembly needs to control the drive belts of two tracks at the same time, this increases the complexity of controlling the curtain opening and closing function. In actual operation, there may be problems such as asynchronous opening and closing of the curtains or inaccurate control. The design of a single motor driving two tracks may wear or fail in long-term use, affecting the normal use of the curtains. Once the motor or clutch fails, the entire curtain system may not work properly.

[0038] Furthermore, the other ends of the first motor assembly 20 and the second motor assembly 30 are also limited to maintain the stability of the overall installation form. Among them, the dual-motor direct-drive power device 100 also includes a bracket 50, and the bracket 50 and the mounting bracket 40 respectively define the two ends of the first motor assembly 20 and the second motor assembly 30.

[0040] The structural and functional forms of the first motor assembly 20 and the second motor assembly 30 are substantially the same. The first motor assembly 20 is taken as an example for illustrative description below, and the second motor assembly 30 can be understood by reference, and will not be described in detail here.
[0041] In one embodiment, the first motor assembly 20 includes a first motor 24, a first reducer 23 connected to the first motor 24, a clutch mechanism 22 connected to the first reducer 23, and a sensing mechanism 60 installed on the mounting bracket 40. The clutch mechanism 22 is arranged around a plurality of detection positions spaced apart from the center line of the first reducer 23, and the sensing mechanism 60 is located on the rotation path of the detection position. The first motor 24 is responsible for providing rotational power, and the first reducer 23 is connected to the first motor 24. The first reducer 23 reduces the speed of the motor output and increases the torque to meet different work requirements. The first motor 24 and the first reducer 23 are assembled together to form a stable power output with controllable speed.
[0042] The dual-motor direct-drive power device 100 further includes a sensing mechanism 60 mounted on the mounting bracket 40, and the sensing mechanism 60 is used to detect the rotation angle of the first output terminal 21. The sensing mechanism 60 detects the rotation angle of the first output terminal 21 through Hall sensing or photoelectric sensing to determine the opening and closing movement timing of the curtain. The sensing mechanism 60 includes a sensing end mounted on the mounting bracket 40 and a movable end mounted on the first motor assembly 20.
[0043] Preferably, the shell part connected to the first output terminal 21 is provided with a plurality of gratings 2211, and the grating 2211 itself or the space between two adjacent gratings 2211 constitutes a detection position. During the rotation of the first output terminal 21, the sensing end outputs an electrical signal at the detection position, thereby constituting a detection. Optionally, the sensing mechanism 60 is configured as a Hall element, and when each grating 2211 moves to the sensing end, the sensing mechanism 60 outputs an electrical signal. Optionally, the sensing mechanism 60 is configured as a photoelectric sensor, and when each grating 2211 moves to the sensing end, the sensing mechanism 60 outputs an electrical signal. The sensing mechanism 60 can output an electrical signal, and the control board 51 can control the start and stop of the first motor assembly 20 based on the electrical signal.
[0044] like Figures 4 to 6 As shown, the first motor assembly 20 includes a first motor 24, a first reducer 23 connected to the first motor 24, and a clutch mechanism 22 connected to the first reducer 23, and the first output end 21 and the clutch mechanism 22 are in an integrated structure. During operation, the grating 2211 is arranged on the clutch mechanism 22, and the grating 2211 is arranged at intervals around the center line of the first reducer 23. When the clutch mechanism 22 rotates, the sensing mechanism 60 can detect these detection positions, thereby determining the position or motion state of the clutch mechanism 22, and then determining the opening and closing stroke of the curtain through the rotation angle of the first motor assembly 20, thereby determining whether the curtain is opened and closed in place.
[0045] The clutch mechanism 22 includes a clutch 222 connected to the first reducer 23, a sleeve member 221 covering the clutch 222, a ferromagnetic ring 224 located at the lower side of the clutch 222, and a magnetic bead 223 movable on the ferromagnetic ring 224. The first output end 21 is an integral structure with the sleeve member 221. The sleeve member 221 is provided with a slot 2212, the clutch 222 rotates and drives the magnetic bead 223 to move to the slot 2212, and the magnetic bead 223 drives the sleeve member 221 to rotate. The ferromagnetic ring 224 is made of a material that can be adsorbed by a magnet, such as iron, steel and other materials. The magnetic bead 223 can be a spherical structure made of magnetic material, which is magnetically adsorbed on the ferromagnetic ring 224 and can roll along the surface of the ferromagnetic ring 224. The clutch 222 rotates along the surface of the ferromagnetic ring 224 and drives the magnetic bead 223 to move.
[0046] The magnetic bead 223 moves in the space between the clutch 222 and the sleeve 221, and the power transmission is connected or disconnected by the cooperation among the magnetic bead 223, the clutch 222 and the sleeve 221. Specifically, when the magnetic bead 223 moves to the slot 2212, the clutch 222 and the sleeve 221 are in close contact, so that the power transmission is realized; when the magnetic bead 223 leaves the slot 2212, the contact between the clutch 222 and the sleeve 221 becomes loose, so that the power transmission is disconnected.
[0047] The number of the slots 2212 on the sleeve member 221 can be set to one or more, and the sleeve member 221 is covered outside the clutch member 222 and can rotate relative to the clutch member 222. The magnetic beads 223 roll on the surface of the ferromagnetic ring 224, and the magnetic beads 223 are moved during the rotation of the clutch member 222. There is a spacing distance between the ferromagnetic ring 224 and the slots 2212, and the spacing distance is smaller than the outer diameter of the magnetic beads 223. When the magnetic beads 223 are partially inserted into the slots 2212, the ferromagnetic rings 224 and the ferromagnetic rings 224 keep in contact with each other. When the clutch member 222 rotates in the opposite direction, the magnetic beads 223 are disengaged from the slots 2212 under the magnetic force of the ferromagnetic ring 224, thereby realizing the engagement and separation of the clutch mechanism 22. The magnetic bead 223 is located on the upper surface of the ferromagnetic ring 224 and moves between the sleeve member 221 and the clutch member 222. When the first motor 24 is running, the clutch member 222 drives the magnetic bead 223 to move to the direction of the slot 2212 and engages with the slot 2212, thereby driving the sleeve member 221 to rotate. When the first motor 24 stops running, due to the retreat of the first motor 24, the magnetic bead 223 no longer abuts against the slot 2212 of the sleeve member 221, and can be separated from the slot 2212 under the magnetic force of the ferromagnetic ring 224, thereby disconnecting the clutch mechanism 22. Preferably, the sleeve member 221 is provided with two symmetrically distributed slots 2212, and two magnetic beads 223 are provided and are respectively distributed on both sides of the clutch member 222. The two slots 2212 can improve the thrust force balance of the magnetic bead 223 and the sleeve member 221.
[0048] The clutch mechanism 22 in the first motor assembly 20 achieves precise control of power transmission through the cooperation of the rotating bearing and the ferromagnetic ring 224 .

The cam portion is approximately an elliptical structure, and a guide curved surface 2221 is provided on the outer peripheral wall of the cam portion. The guide curved surface 2221 ensures that the magnetic beads 223 in contact with it can move according to a predetermined path. Among them, the curve radius of the guide curved surface 2221 gradually increases from one end to the other end, providing the magnetic beads 223 with a continuously changing contact force, and the magnetic beads 223 can enter or leave the card slot 2212 under the guidance of the guide curved surface 2221. Preferably, the outer peripheral wall of the cam portion is provided with four sections of guide curved surfaces 2221, wherein the two sections of guide curved surfaces 2221 located on the same long side of the cam portion are symmetrically arranged.
[0050] In one embodiment, the first reducer 23 includes a plurality of planetary gear sets 231 connected to the first motor 24, an inner gear sleeve 232 sleeved on the planetary gear set 231, and an output shaft frame 233 connected to the planetary gear set 231, the inner gear sleeve 232 is meshed and connected with the planetary gear set 231, and the output shaft frame 233 is connected to the clutch 222.
