[0029] In a specific embodiment, the manual-automatic window opener includes an output shaft 4, a hand-cranked input shaft 5, a spur gear and a motor 11. The axial direction of the output shaft 4 is perpendicular to the axial direction of the hand-cranked input shaft 5. The lower end of the hand-cranked input shaft 5 is provided with a first conical tooth 51, and the input end of the output shaft 4 is provided with a second conical tooth 41. The output shaft 4 is connected to the hand-cranked input shaft 5 by meshing the second conical tooth 41 with the first conical tooth. The motor shaft of the motor 11 is connected to the spur gear 61 through the planetary gear set 7. The motor input shaft 6 of the spur gear 61 is provided with a third conical tooth facing the output shaft 4 and the hand-cranked input shaft 5. Through the transmission connection after the engagement of the second bevel teeth 41, in the first driving mode, the motor 11 drives the planetary gear set 7 to rotate until the planetary gears of the planetary gear set 7 engage with the spur gear 61, thereby driving the motor input shaft 6, the hand-cranked input shaft 5, and the output shaft 4 to rotate. In the second driving mode, the hand-cranked input shaft 5 is controlled to rotate in a first direction, driving the motor input shaft 6, the spur gear 61, and the planetary gear set 7 to rotate in turn, so that the planetary gear set 7 is separated from the motor shaft of the motor. Afterwards, the hand-cranked input shaft 5 is controlled to rotate in a second direction to drive the output shaft 4 to rotate, wherein the first direction is opposite to the second direction.

[0030] By connecting the spur gear 61 and the motor 11 through the planetary gear set 7, in the first driving mode, the motor drives the planetary gear set 7 to rotate until the planetary gears of the planetary gear set 7 are engaged with the spur gear 61, thereby driving the motor input shaft 6, the hand-cranked input shaft 5, and the output shaft 4 to rotate; in the second driving mode, the hand-cranked input shaft 5 is controlled to rotate in a first direction, driving the motor input shaft 6, the spur gear 61, and the planetary gear set 7 to rotate in turn, so that the planetary gear set 7 is separated from the motor shaft of the motor; thereafter, the hand-cranked input shaft 5 is controlled to rotate in a second direction to drive the output shaft 4 to rotate, wherein the first direction is opposite to the second direction, thereby realizing the manual and automatic integrated function of the window opener, and realizing the motor separation during manual operation, thereby reducing the rotational force required for manual operation.

[0031] In order to further reduce the difficulty of manufacturing and assembly, in one embodiment, the first conical teeth and the third conical teeth have the same shape and size, the axial direction of the output shaft 4 of the motor is parallel to the axial direction of the output shaft 4 and the axial direction of the motor input shaft 6 of the spur gear 61, and the motor input shaft 6 of the spur gear 61 is collinear with the axis of the output shaft 4.

[0032] By designing the first conical teeth and the third conical teeth to be of the same shape and equal size, during use, if the third conical teeth are smaller, then the number of teeth distributed circumferentially is smaller, and the angle of rotation of the unit tooth becomes larger, which makes the resistance during rotation greater and increases the difficulty of use. The third conical teeth will not be larger, which will increase the overall size and the difficulty of installation. At the same time, the number of rotations required to disengage from the motor will be increased, which will prolong the time of single use and reduce the efficiency of use.

[0033] In this application, there is no limitation on the shape, size, etc. of the first conical teeth and the third conical teeth, and there is no limitation on the relative arrangement positions of the various devices.

The base 2 is provided with a gear rack 9 and a motor connector 10. The output shaft 4, the spur gear 61, and the hand-cranked input shaft 6 are fixed to the gear rack 9, and the motor connector 10 is used to fix the motor 11.

[0035] By setting up a base 2 and a gear rack 9, the relevant gear structure is fixed. The base 2 can carry the relevant components and can also be installed at the required installation position through the base 2, which improves the convenience of installation and protects the relevant components at the same time. During use, the vibration generated by the relevant components can be eliminated by the base 2, thereby improving the efficiency and reliability of use.

[0036] The present application does not limit the structure of the base 2 and the gear rack 9 and the installation method of related components.

[0037] In order to further facilitate the control of the use of the motor, in one embodiment, the manual-automatic window opener also includes an adjustable stall plate 8 fixed to the base 2 and connected to the motor, and a dial 3 arranged on the adjustable stall plate 8. The adjustable stall plate 8 is used to limit the maximum current input to the motor, and the dial 3 is used to adjust the current value input to the motor, thereby controlling the output torque of the motor.

[0039] The present application includes but is not limited to the adjustable stall plate 8 and the dial 3, and there is no limitation on the installation method of the adjustable stall plate 8 and the dial 3.

[0042] By providing the upper cover 1, all components are wrapped and protected, and corresponding through holes are provided to facilitate external input and output of internal components, thereby improving ease of use.

[0043] The material, shape, structure and installation method of the upper cover 1 are not limited in this application.

[0044] The upper cover 1 is in the shape of a cuboid, a semi-cylinder, a hemisphere, or other shapes.

[0045] In order to further improve the efficiency of use, in one embodiment, the manual-automatic window opener also includes a clutch state detection device for detecting the connection state between the spur gear and the planetary gear set 7, and the clutch state detection device is a photoelectric clutch state detection device or a current clutch state detection device.

[0046] By detecting the connection status between the spur gear and the planetary gear set 7 through the clutch status detection device, the clutch status can be obtained in real time. In the subsequent process of changing from automatic to manual, on the one hand, the clutch status detection device can be used to determine whether the operation is proper and in place without the need for subsequent clutch operation.

[0050] The present application does not limit the type of prompt device, and the prompt device may be an LED indicator light or a voice indication device, or other prompt devices.

[0051] In one embodiment, the manual-automatic window opener has a cover 1 secured to a base 2 with screws and includes an output shaft 4 and a hand-cranked input shaft 5. The cover 1 has a square hole 11 for convenient adjustment of the dial 3. The output shaft 4 connects to the hand-cranked window opener; the hand-cranked input shaft 5 connects to the hand crank to manually open the window opener. The dial 3 controls the motor's output torque by controlling the stall current.

[0052] The clutch control system is used as follows:

[0053] Electric engagement:

[0054] Counterclockwise: The motor rotates counterclockwise after being energized, and the planetary gear set 7 rotates counterclockwise until the first planetary gear 71 engages with the spur gear 61 on the electric input shaft 6, thereby driving the electric input shaft 6, the hand-cranked input shaft 5, and the output shaft to rotate 4.

[0055] Clockwise: When the motor is powered on, it rotates clockwise, and the planetary gear set 7 rotates clockwise until the second planetary gear 72 engages with the spur gear 61 on the electric input shaft 6, thereby driving the electric input shaft 6, the hand crank input shaft 5, and the output shaft to rotate 4.

[0056] Manual separation:

[0057] After the motor stops running counterclockwise, the first planetary gear 71 meshes with the spur gear 61. Counterclockwise rotation of the hand crank input shaft 5 drives the electric input shaft 6 counterclockwise. This rotation of the electric input shaft 6 then drives the planetary gear set 7 clockwise, causing the planetary gear set 7 to passively disengage, thereby achieving motor disengagement during manual cranking. After disengagement, the hand crank input shaft 5 only drives the output shaft 4 clockwise.

[0058] After the motor stops running clockwise, the first planetary gear 71 meshes with the spur gear 61. Clockwise rotation of the hand-crank input shaft 5 drives the electric input shaft 6 clockwise. This rotation of the electric input shaft 6 then drives the planetary gear set 7 counterclockwise, causing the planetary gear set 7 to passively disengage, thereby achieving motor disengagement during manual cranking. After disengagement, the hand-crank input shaft 5 only drives the output shaft 4 counterclockwise.

[0059] The output shaft 4 is provided with a gear 41 which meshes with the helical gear 51 on the hand-cranked output shaft 5 .

[0060] A bevel gear 51 is provided on the hand-cranked output shaft 5 , which meshes with the bevel gear 41 on the output shaft 4 and the bevel gear 62 on the electric input shaft 6 ; a bevel gear 62 is provided on the electric output shaft 6 , which meshes with the bevel gear 51 on the hand-cranked output shaft 5 .

[0061] A spur gear 61 is provided on the electric input shaft 6 for controlling the engagement and disengagement of the planetary gear set 7 .

[0062] The planetary gear set 7 is provided with a first planetary gear 71 and a second planetary gear 72 for controlling engagement and disengagement with the spur gear 61 .

[0063] The adjustable stall plate 8 is provided with a dial 3, through which the stall current can be adjusted, thereby controlling the output torque of the motor.

[0064] The above solution can realize manual and automatic operation of the window opener; it can realize motor separation during manual operation, reducing the rotational force required for manual cranking; the output force of the device can be adjusted to prevent excessive torque from damaging the hand-cranked chain box.

[0065] To sum up, the manual-automatic window opener provided by the embodiment of the present invention is connected between the spur gear and the motor through a planetary gear set. In a first driving mode, the motor drives the planetary gear set to rotate until the planetary gears of the planetary gear set are engaged with the spur gear, thereby driving the motor input shaft, the hand-cranked input shaft, and the output shaft to rotate. In a second driving mode, the hand-cranked input shaft is controlled to rotate in a first direction, driving the motor input shaft, the spur gear, and the planetary gear set to rotate in turn, so that the planetary gear set is separated from the motor shaft of the motor. Thereafter, the hand-cranked input shaft is controlled to rotate in a second direction to drive the output shaft to rotate, wherein the first direction is opposite to the second direction, thereby realizing the manual-automatic function of the window opener, and realizing the motor separation during manual operation, thereby reducing the rotational force required for manual operation.

[0066] The above describes in detail the manual-automatic window opener provided by the present invention.
