Description

Technical Field

[0001] This utility model relates to the field of window opener technology, and more specifically to a dual-clutch motor structure. Background Technology

[0002] Window openers enable automatic opening and closing of windows. Among them, chain window openers drive the opening and closing of window sashes through a chain system. Existing electric window openers generally have a manual mode, which is equipped with a clutch function in the transmission mechanism to achieve the function of switching between manual and electric modes.

[0003] In electric curtain systems, tubular motors are used. To enable manual operation of the electric curtains, a magnetic bead clutch is installed inside the tubular motor. Manually pulling the curtains will not affect the motor of the tubular motor.

[0004] Existing electric window openers cannot manually push or pull curtains when the window is in electric open or closed mode. The motor must be turned off first, and then the manual mode must be switched, which is quite complicated. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dual-clutch motor structure, so that the window can be manually pushed or pulled when the window is electrically opened or closed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-clutch motor structure, including a housing, a motor slidably connected inside the housing, a transmission component rotatably connected to the housing, the motor including an output component and a reducer, a magnetic bead clutch provided between the output component and the reducer to disconnect or connect the transmission path between the reducer and the output component, a clutch mechanism provided between the output component and the transmission component, and the motor sliding relative to the housing to disconnect or connect the transmission path between the output component and the transmission component through the clutch mechanism.

[0007] As a further improvement of this utility model, the magnetic bead clutch includes a clutch component, an iron component, and two magnetic beads. The clutch component is fixedly connected to the output end of the reducer, the iron component is fixedly connected inside the motor, and the magnetic beads are attracted to the iron component and located on opposite sides of the clutch component. The output component has a receiving groove at one end facing the reducer, and the magnetic beads are located in the receiving groove. Two opposing grooves adapted to the magnetic beads are formed on the inner wall of the receiving groove.

[0008] As a further improvement of this utility model, the reducer is a planetary gear reducer.

[0009] As a further improvement of this utility model, the reducer includes an inner gear sleeve, and the iron part meshes with the inner gear sleeve.

[0010] As a further improvement of this utility model, a bearing is connected between the transmission component and the housing.

[0011] As a further improvement of this utility model, the clutch mechanism includes an elastic reset component, and the transmission component is connected to the output component through the elastic reset component.

[0012] As a further improvement of this utility model, the elastic reset assembly includes an elastic element and a connecting element. The transmission element has a first spline groove at one end facing the output element. The connecting element's end away from the output element engages with the first spline groove. The elastic element is disposed between the connecting element and the bottom wall of the first spline groove.

[0013] As a further improvement of this utility model, the output component has a second spline groove on the side facing the connector, and the end of the connector away from the transmission component engages with the second spline groove.

[0014] As a further improvement of this utility model, the elastic element is a compression spring.

[0015] As a further improvement of this utility model, the connector is provided with a slot, and the transmission member is inserted with a rod that passes through the first spline groove, the rod passing through the slot.

[0016] The beneficial effects of this utility model are as follows: The addition of a magnetic bead clutch in this utility model allows the user to directly push or pull the window while the motor is working normally to open or close the window. This speeds up the opening or closing process without affecting the motor and preventing motor damage. Compared to a single clutch mechanism, where the user needs to stop the motor and manually disengage the clutch before pushing the window, the dual-clutch structure eliminates this series of operations.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] Reference Figures 1 to 6 As shown, a dual-clutch motor structure of this embodiment includes a housing 1, and a window opener frame is also fitted outside the housing 1; a motor 2 is slidably connected inside the housing 1, and a transmission component 3 is rotatably connected to the housing 1. Preferably, the transmission component 3 is a bevel gear. A transmission mechanism is also provided in the housing 1. The transmission mechanism includes at least a plurality of gears. The bevel gear meshes with one of its adjacent gears to realize transmission and drive the chain of the chain window opener to move.

[0026] The motor 2 includes an output component 21 and a reducer 22. In this solution, the reducer 22 is set inside the motor 2, which is more integrated and easier to install as a whole. In the prior art, the reducer is generally set inside the transmission mechanism, and the reduction gears need to be installed one by one.

[0027] The reducer 22 is a planetary gear reducer, which facilitates multi-stage reduction.

[0028] A magnetic bead clutch is provided between the output component 21 and the reducer 22 to disconnect or connect the transmission path between the reducer 22 and the output component 21. The clutch of the tubular motor used on the curtain is applied to this window opener and cooperates with the clutch mechanism to form a dual-clutch structure.

[0029] A clutch mechanism is provided between the output component 21 and the transmission component 3. The motor 2 slides relative to the housing 1 to disconnect or connect the transmission path between the output component 21 and the transmission component 3 through the clutch mechanism. A lever is installed on the housing 1 to drive the motor 2 to move along its axial direction.

[0030] During the window opening process, the magnetic bead clutch and the clutch mechanism are both in a connected state. When the user pushes the window while the motor 2 is working, the magnetic bead clutch can be disengaged. If the motor 2 does not stop working, the window can be pushed directly. At this time, the clutch mechanism is in a connected state.

[0031] Compared to a single clutch mechanism, where the user needs to stop motor 2 and manually disengage the clutch before pushing the window while motor 2 is running, the dual-clutch structure eliminates this series of operations.

[0032] Reference Figure 2 , Figure 3 and Figure 4 As shown, preferably, the magnetic bead clutch includes a clutch element 41, an iron element 42, and two magnetic beads 43. The clutch element 41 is fixedly connected to the output end of the reducer 22, the iron element 42 is fixedly connected to the motor 2, and the magnetic beads 43 are attracted to the iron element 42 and are located on opposite sides of the clutch element 41. The output element 21 has a receiving groove 211 at one end facing the reducer 22, and the magnetic beads 43 are located in the receiving groove 211. Two opposite grooves 44 adapted to the magnetic beads 43 are opened on the inner wall of the receiving groove 211.

[0033] The clutch mechanism structure from the opening and closing curtain tube motor was misappropriated;

[0034] The motor 2 also includes a motor, which is connected to the input end of the reducer 22. When the motor rotates forward, the reducer 22 causes its output end to rotate forward. At this time, the clutch 41 rotates forward, driving the magnetic bead 43 to partially embed into the corresponding groove 44, causing the output part 21 to rotate forward and the window to be opened.

[0035] When the user pushes the window at this time, the speed at which the window opens is greater than the speed at which the window opens when motor 2 works;

[0036] The output component 21 continues to rotate forward, and the speed of the forward rotation is greater than the driving speed of the clutch component 41; thereby causing the output component 21 to disengage from the magnetic bead 43, that is, the magnetic bead 43 disengages from the corresponding groove 44; thus realizing the disengagement function of the magnetic bead clutch.

[0037] When the motor reverses, the window is closed. When the curtains are pulled, the output component 21 reverses, which works on the same principle as forward rotation.

[0038] With the magnetic bead clutch, users can quickly open or close the window while the motor 2 is running.

[0039] The iron part 42 is fixedly connected to the housing of the motor 2, and can be fixed with screws;

[0040] Reference Figure 3 As shown, preferably, the reducer 22 includes an inner gear sleeve, and an iron piece 42 meshes with the inner gear sleeve. The iron piece 42 is located between the inner gear sleeve and the output piece 21, thereby forming a positioning. Through the meshing between the iron piece 42 and the inner gear sleeve, the iron piece 42 can be prevented from rotating as the magnetic bead 43 moves.

[0041] Reference Figure 2 , Figure 3 and Figure 5 As shown, a bearing 11 is connected between the transmission component 3 and the housing 1 to increase the rotational stability of the transmission component 3.

[0042] The clutch mechanism includes an elastic reset component 5. The transmission component 3 is connected to the output component 21 through the elastic reset component 5. When the moving motor 2 moves toward the transmission component 3, the output component 21 may not be engaged with the transmission component 3. At this time, the elastic reset component 5 can provide elastic deformation to prevent damage to the output component 21 and the transmission component 3.

[0043] The elastic reset assembly 5 includes an elastic element 51 and a connecting element 52. The elastic element 51 can be a spring sheet, preferably a compression spring. Compression springs have a longer service life and are easier to install.

[0044] The transmission component 3 has a first spline groove 31 at one end facing the output component 21. The end of the connecting component 52 away from the output component 21 engages with the first spline groove 31. The elastic component 51 is disposed between the connecting component 52 and the bottom wall of the first spline groove 31. The first spline groove 31 facilitates the installation of the elastic component 51 and provides the connecting component 52 with a sliding space. When the user drives the motor 2 to move towards the transmission component 3 via the lever, if the output component 21 fails to engage with the connecting component 52, the output component 21 will push the connecting component 52 to move towards the transmission component 3, thereby compressing the elastic component 51 and preventing damage to the output component 21.

[0045] When the motor 2 rotates, the output component 21 will rotate, and the output component 21 will re-align with the connecting component 52. Under the action of the restoring force of the elastic component 51, the output component 21 will re-engage with the connecting component 52.

[0046] Preferably, the output component 21 and the connecting component 52 are also connected by a spline. The output component 21 has a second spline groove 212 on the side facing the connecting component 52. The end of the connecting component 52 away from the transmission component 3 engages with the second spline groove 212. An external spline is provided on the connecting component 52.

[0047] Reference Figure 5 and Figure 6 As shown, the connector 52 has a slot 521, and the transmission component 3 has a rod 522 that passes through the first spline groove 31. The rod 522 passes through the slot 521 and restricts the movement range of the connector 52 to a certain extent, which can prevent the connector 52 from separating from the first spline groove 31 on the transmission component 3 and facilitates installation.

[0048] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
