Description

Technical Field

[0001] The utility model relates to a planetary swing gear clutch device. Background Art

[0002] Electric actuators such as smart door locks, electric curtains, automatic doors and windows, security and fire protection have been widely promoted and applied in modern buildings. Various intelligent electric actuators are becoming more and more widely used, especially the electric door and window openers of automatic doors and windows. Most of them only have electric opening and closing functions. When there is a power outage or the motor and control fail, they cannot be opened or closed, and they cannot be switched freely between manual opening and automatic opening.

[0003] At present, some electric door and window openers on the market also have manual opening and closing functions, but they all have manual release or manual clutch devices. Before manually opening and closing doors and windows, the manual release or manual clutch device must be operated first, which is troublesome to operate and affects the appearance of door and window products and building decoration.

[0004] The utility model patent (authorization announcement number: CN210178797 U) proposes a solution based on a manual-automatic clutch with a movable planetary gear, but lacks a binding mature technical solution for the effective engagement and disengagement of the planetary gear and the drive gear, which needs further improvement and perfection. Utility Model Content

[0008] Two planetary gear shafts are symmetrically arranged at both ends of the planetary gear carrier, and planetary gears are arranged on the two planetary gear shafts.

[0009] The utility model transitionally connects the front driving gear and the rear reduction gear through a novel planetary swing gear clutch device, and the planetary gear and the rear reduction gear are in a meshing or disengaging state through the swing of the planetary swingable component, thereby realizing the automatic and manual integrated function of the door opening curtain machine.

[0015] A novel planetary swing gear clutch device is characterized in that it includes a front drive gear 11, a central gear set 01, a planetary gear swingable component, and a rear reduction gear 08; the central gear set 01 includes a central gear shaft 12, on which a front meshing gear 09 and a sun gear 10 are mounted, and the sun gear 10 is coaxially fixed to the front meshing gear 09, wherein the front meshing gear 09 is meshed with the front drive gear 11; the planetary gear swingable component includes a planetary gear carrier 02, a planetary gear shaft fixed to the planetary gear carrier 02, a clamping spring 07, a planetary gear 06, and a pressure plate 05 in sequence; the planetary gear 06 is mounted on the planetary gear carrier 02 through the planetary gear shaft, and is located between the clamping spring 07 and the pressure plate 05; the planetary gear A magnetic column 04 is fixed on one side of the gear frame; the planetary gear oscillating component is mounted on the root of the sun gear 10, and the sun gear 10 is meshed with the planetary gear 06; the front driving gear 11 is driven to mesh with the front meshing gear 09 to rotate, and the planetary gear 06 generates friction with the pressure plate 05 under the action of the compression spring 07. The friction causes the planetary gear 06 to be unable to rotate smoothly. The sun gear 10 drives the planetary gear frame 02 to swing synchronously around the central gear shaft 12, so that the planetary gear 06 can be in a state of meshing or disengagement in the opposite direction with the rear reduction gear 08; when the driving force reaches the point where the friction on the upper and lower sides of the planetary gear 06 is overcome, the sun gear 10 meshes with the planetary gear 06 to make it rotate normally, thereby driving the rear reduction gear 08 to rotate normally.

[0016] Furthermore, two planetary gear shafts are symmetrically arranged at both ends of the planetary gear carrier 02, and planetary gears 06 are arranged on both planetary gear shafts.

[0017] In this embodiment, the planetary gear automatic clutch device is normally open, that is, the static state is disengaged (such as Figure 2 state); when it is necessary to open the door and window, the controller opens the command to control the motor to rotate (forward) through the front drive gear 11 to drive the front meshing gear 09 of the central gear group to rotate, and the sun gear 10 runs synchronously. The sun gear 10 meshes with the planetary gear 06. The planetary gear 06 generates friction with the pressure plate 05 under the action of the compression spring 07. The friction makes the planetary gear 06 mesh with the sun gear 10 but cannot smoothly rotate. The planetary gear 06 drives the planetary gear carrier 02 to rotate and swing synchronously around the central gear shaft 12 until the planetary gear 06 contacts and meshes with the rear reduction gear 08 and swings into place (such as Figure 3 state); when the driving force reaches the level of overcoming the friction between the upper and lower sides of the planetary gear 06, the sun gear 10 meshes with the planetary gear 06, and the planetary gear 06 rotates normally, thereby driving the rear reduction gear 08 to rotate normally, and transmitting power downward to the output mechanism through the gear meshing with it, driving the door curtain machine to open the door curtain. After the door curtain is fully opened or the stop command is executed, the electric motor instantly rotates in the opposite direction (reverses) for a certain number of circles, and the planetary gear 06 drives the planetary gear frame 02 to rotate and swing synchronously around the central gear shaft 12. When the magnetic column of the planetary gear frame 02 corresponds to the Hall position detection circuit simultaneously provided in the housing of the door curtain machine, it stops in place; at this time, the planetary gear 06 has swung back and away from the gear meshing with it, and returned to the clutch disengaged state (such as Figure 2 When the doors and windows need to be closed, the controller closes the command to control the curtain machine to perform the opposite action to the opening of the doors and windows. When the doors and windows are closed, the meshing state (such as Figure 4 After the clutch is fully closed or the stop command is executed, the electric motor instantly rotates in the opposite direction (reverses) for a certain number of circles, and the planetary gear 06 drives the planetary gear carrier 02 to rotate and swing synchronously around the central gear shaft 12, returning to the clutch disengaged state (as shown in FIG. Figure 2 state).

[0018] During the process of the planetary gear and the rear reduction gear being disengaged, there may be a situation where the planetary gear on the other side is not disengaged enough or the swing angle is too large, causing the planetary gear on the other side to mesh with the reduction gear. Therefore, a magnetic column is set between the two planetary gears on the planetary gear rack, and a Hall position detection circuit is set at the corresponding position in the housing of the door opening curtain machine to determine whether the planetary gear and the rear reduction gear are in a completely disengaged state. If they are not completely disengaged, the control circuit of the door opening curtain machine drives the motor to rotate forward or reverse for a second disengagement to ensure that the planetary gear and the rear reduction gear are in a completely disengaged state (such as Figure 2 status), waiting for manual opening or electric opening and closing of door curtains.

[0019] Furthermore, the novel planetary swing gear clutch device may also include a motor, a worm gear, a central gear set 01, a planetary gear swingable component, and a rear reduction gear 08; the rear reduction gear 08 drives a chain, a rack, a swing arm, etc. to promote the opening and closing of doors, windows, curtains or other electric actuators.

[0020] Furthermore, the front meshing reduction mechanism of the central gear set 01 can be set as a worm gear and several gears, but is not limited to a worm gear reduction mechanism. It can be other transmission reduction mechanisms, and can also be realized in meshing combination with a planetary swing gear clutch device to achieve automatic seamless automatic clutch.

[0021] This embodiment is only an implementation case to illustrate the principle of automatic clutch execution of the door opening curtain machine. In actual applications, the design structure of the present invention can also be used to adopt other front or rear transmission mechanisms to realize door opening curtain machines different from the implementation case, all of which are protected by the present utility model.
