Description

Technical Field

[0001] This utility model relates to the technical field of power control mechanisms for wing fans, and in particular to a control mechanism and a window opener. Background Technology

[0002] A window opener is installed on the sash part that moves around a pivot axis, such as on a window, to control the automatic opening and closing of the window. For example, the publication document with announcement number CN103883197A provides a window opener stroke control mechanism. This control mechanism uses a circuit board to record the number of pulse or current changes to determine the number of motor rotations, and the number of rotations corresponds to the precise stroke of the window opener.

[0003] The window opener uses a motor to drive the opening mechanism in both forward and reverse rotation to achieve the opening angle. However, when the window opener has manual and automatic switching functions, the opening angle cannot be determined solely by the number of motor rotations. Furthermore, it is necessary to determine whether the window opener is currently in manual or automatic mode to avoid technical issues related to inconsistent operation. Therefore, improvements are needed. Utility Model Content

Detailed Implementation

[0024] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0025] like Figures 1 to 5 As shown, this utility model provides a control mechanism 20, which is applied to a window opener and can control the window opening mechanism 40 of the window opener to perform automatic opening and closing functions. The window opener includes a housing 10 and a sliding drive assembly 30. The drive assembly 30 serves as the power output part of the window opener. The drive assembly 30 slides relative to the housing 10, thereby switching the on / off state of the power output part so that the window opener can perform manual and automatic opening and closing functions. The drive assembly 30 uses sliding to switch between the manual and automatic positions of the window opener to realize manual and automatic driving of the window opener.

[0026] The drive assembly 30 includes a motor, and a magnetic component 223 is fixedly connected to the output end of the motor. Preferably, the magnetic component 223 is a magnetic ring with at least two magnetic poles.

[0027] The control mechanism 20 includes a control component 21, which includes at least one first Hall element 221 and at least one second Hall element 222. There is a gap between the first Hall element 221 and the second Hall element 222, and the line connecting the first Hall element 221 and the second Hall element 222 in the horizontal projection direction is parallel to the central axis of the motor.

[0028] The first Hall element 221 is located in the sliding direction of the magnetic component 223. The first Hall element 221 is used to sense the position parameters of the magnetic component 223 and is electrically connected to the control component 21. After the magnetic component 223 slides into the sensing area, the first Hall element 221 outputs an electrical signal. The control component 21 receives this signal and outputs an indication message. The first Hall element 221 and the magnetic component 223 work together to determine the position of the drive component 30, thereby allowing the control component 21 to output the corresponding operating status, facilitating the user's judgment of the window opener's operating parameters.

[0029] The second Hall element 222 is used to sense the rotation parameters of the magnetic component 223. The first Hall element 221 and the second Hall element 222 are distributed at intervals along the sliding direction of the magnetic component 223. The second Hall element 222 can detect the rotation angle of the magnetic component 223 to calculate the number of rotations and the angle of the magnetic component 223.

[0030] Optionally, a single first Hall element 221 may be configured. When the magnetic element 223 moves with the driving assembly 30 to the sensing area of ​​the first Hall element 221, the first Hall element 221 outputs a position signal. When the magnetic element 223 moves away from the sensing area of ​​the first Hall element 221 with the driving assembly 30, the first Hall element 221 outputs a disengagement signal.

[0031] Optionally, two first Hall elements 221 are provided, and the line connecting the two first Hall elements 221 is perpendicular to the central axis of the motor;

[0032] Two first Hall elements 221 are disposed opposite to each other on the control component 21. The magnetic element 223 moves with the drive component 30 and slides between the two first Hall elements 221 to realize position detection. When the magnetic element 223 moves to the position of the first Hall element 221, the window opener is in manual drive mode.

[0033] Preferably, two second Hall elements 222 are provided, and the line connecting the two second Hall elements 222 is perpendicular to the center line of the motor;

[0034] The second Hall element 222 and the first Hall element 221 are spaced apart along the sliding direction of the magnetic element 223. The two second Hall elements 222 are positioned relative to each other on the control assembly 21, and the magnetic element 223 moves with the drive assembly 30. When the magnetic element 223 moves between the two second Hall elements 222, the two second Hall elements 222 can detect the rotation angle of the magnetic element 223 as it rotates, and output an electrical signal corresponding to the rotation angle and number of rotations of the magnetic element 223. Optionally, when the magnetic element 223 moves between the two second Hall elements 222, the window opener is in automatic operation.

[0035] Optionally, the spacing between the two first Hall elements 221 is equal to the spacing between the two second Hall elements 222. This ensures that both the first Hall element 221 and the second Hall element 222 can sense the magnetic element 223.

[0036] like Figures 3 to 5 As shown, the first Hall element 221 and the second Hall element 222 are located within a portion of the sliding area of ​​the drive assembly 30. The first Hall element 221 is positioned to detect the working position of the drive assembly 30, while the second Hall element 222 detects the rotation angle of the magnetic component 223. The first Hall element 221 and the second Hall element 222 are spaced apart along the sliding direction of the drive assembly 30 to prevent mutual interference while simultaneously outputting detection electrical signals at corresponding positions.

[0037] In a preferred embodiment, the control component 21 includes a first control board 211, and the first Hall element 221 and the second Hall element 222 are both electrically connected to the first control board 211;

[0038] The first control board 211 is mounted on the housing 10, and the first Hall element 221 and the second Hall element 222 are both mounted on the first control board 211. The position and height of the first control board 211 on the housing 10 are adjustable, thereby adapting the mounting positions of the first Hall element 221 and the second Hall element 222 to the active area of ​​the magnetic component 223. The first Hall element 221 can accurately sense the position of the magnetic component 223, and the sensing areas of the first Hall element 221 and the magnetic component 223 can be easily adjusted and matched.

[0039] In a preferred embodiment, the first control plate 211 is provided with a first clearance notch 213, which extends to the first Hall element 221. When there is one first Hall element 221, it is located on one side of the first clearance notch 213. When there are two first Hall elements 221, they are located on both sides of the first clearance notch 213. At least part of the magnetic element 223 extends into the first clearance notch 213. The first clearance notch 213 is provided in a notch shape along the first control plate 211. The magnetic element 223 slides along the first clearance notch 213, thereby being detected and sensed by the first Hall element 221 and the second Hall element 222.

[0040] In another preferred embodiment, the control component 21 includes a first control board 211 and a second control board, the first control board 211 and the second control board being arranged vertically spaced apart, and the first Hall element 221 and the second Hall element 222 being electrically connected to the first control board 211 and the second control board, respectively.

[0041] The first control board 211 and the second control board are detachably connected. The two control boards are distributed in parallel and connected by studs to adjust the installation height, thereby flexibly setting the range and angle of the sensing area of ​​the magnetic component 223.

[0042] Preferably, both the first control board 211 and the second control board are provided with second clearance notches, and both second clearance notches extend to the first Hall element 221.

[0043] The two second clearance gaps can reduce the distance between the first control plate 211 and the second control plate, and prevent interference between the first control plate 211 and the second control plate and the magnetic component 223.

[0044] The control component 21 also includes an indicator element 212.

[0045] At least one indicator element 212 is provided on the first control board 211 or the second control board. The indicator element 212 outputs corresponding indicator information according to the signal from the detection component 22. The indicator element 212 is used to output indicator information such as light, sound or prompt tone so that the operator can identify the operating status of the window opener.

[0046] Preferably, the indicating element 212 includes one or more of an indicator light, a buzzer, a display, and a speaker. The indicator light can output a light signal, such as a flashing light signal or a light signal that changes color. The buzzer can output a sound of varying duration. The display can directly output text or images to visually show the corresponding parameters. The speaker can directly output speech information for the operator's convenience.

[0047] The control mechanism 20 disclosed in the above embodiments is applied to a window opener, wherein the window opener includes a window opening mechanism 40 and a control mechanism 20. The control component 21 determines whether the window opening mechanism 40 is in a manual or electric state based on the output signal of the first Hall element 221. When the drive component 30 moves, the first Hall element 221 detects the drive component 30 and outputs a corresponding electrical signal, which indicates whether the window opener is in a manual or electric state.
