detailed description

The present invention will be further specifically described below with reference to the drawings. An electric door opening and closing device with a clutch device, which includes a main body 1 and a trigger 2 mounted on a living hinge, the main body 1 is provided with an accommodating groove 3, and a draw rod 4 and a pull bar 5 are installed in the accommodating groove 3, One end of the pull rod 4 is articulated with the trigger 2 and the other end is hinged with the pull bar 5. The other end of the pull bar 5 is movably placed in the accommodating groove 3 through the guide pin 6. The accommodating groove 3 is also provided with a spring 7. One end of the spring 7 is connected to the pull rod 4 and the other end is connected to the main body 1. The main body 1 is also equipped with an electric drive device. The electric drive device is connected to the pull rod 5 through a clutch device. The electric drive device is connected to the clutch device The driving brace 5 moves in the accommodating groove 3 and indirectly drives the trigger 2 to swing.

The clutch device is a through hole 92 provided on both sides of the connecting plate 9, and an elastic boss 93 is installed in the through hole 92 and passes through the through hole 92 and protrudes from the side wall of the connecting plate 9. Correspondingly: the pull bar 5 A positioning hole 51 is provided, the connecting plate 9 is placed inside the brace 5 and the elastic boss is caught in the positioning hole 51.

The electric drive device is an electric screw 81 driven by a reduction motor 8. The electric screw 81 is screwed to the screw hole 91 on the connecting plate 9, and the other end of the connecting plate 9 is connected to the brace 5.

The elastic boss 93 is a dome boss provided on both sides of the U-shaped plate 94. The dome boss and the U-shaped plate 94 are integrally formed.

The inner side of the connecting plate 9 is provided with a mounting groove 95, and the two supporting legs of the U-shaped plate 94 are elastically installed in the mounting groove. The U-shaped plate is provided with a positioning hole 96, and a positioning pin 97 passes through the positioning hole 96 to connect The board 9 is connected.

The reduction gear motor 8 and the main body are installed through a motor frame 82. The electric screw 81 is fixed to the front end of the reduction motor. The electric screw 81 extends through the main body of the motor frame 82 into the connecting plate 9.

The motor frame 8 is also provided with a limiting plate 83, and a limiting slot 84 is provided on the limiting plate 83, and the electric screw 81 passes through the limiting slot 84 and is screwed to the connecting plate.

The surface of the electric screw 81 is also surrounded by a stop plate 85, and the stop plate 85 is located between the limiting plate 83 and the main body of the motor frame.

Working principle: As shown in FIGS. 4, 5 and 6, the electric drive device is an electric screw 81 driven by a reduction motor 8. The electric screw 81 is screwed to the threaded hole 91 on the connecting plate 9, and the other end of the connecting plate 9 is connected to Pull bar 5 is connected. When it is necessary to open and close the door, the control system energizes the electric screw 81 to make it rotate. When the electric screw rotates, it is screwed with the threaded hole 91 on the connecting plate 9 to drive the connecting plate to move, and the connecting plate drives the pull rod to realize the drive The trigger swings to finally open and close the box door.

Among them, in order to prevent the user from being unable to open or close the cabinet door due to the external force unable to drive the electric screw during the power outage during use, in this case, a clutch device is provided between the electric drive device and the pull bar 5. Among them, the clutch device includes through holes 92 provided on both sides of the connecting plate 9, and an elastic boss 93 is installed in the through hole 92 and passes through the through hole 92 and protrudes from the side wall of the connecting plate 9, correspondingly: the pull bar 5 is provided There is a positioning hole 51, the connecting plate 9 is placed inside the brace 5, and the elastic boss is locked in the positioning hole 51. When a power outage occurs, or the user does not know that the device is manually opened for electric opening, the user's force forces the elastic boss 93 to separate from the positioning hole 51 on the pull bar 5, at this time, the hinge becomes manual operation Door hinges. When the power supply is restored, the user operates the cabinet door and drives the pull bar to move, so that the positioning hole on the pull bar is again docked with the elastic boss 93, the connecting plate can be connected to the pull bar 5 again, and the electric drive device drives the connecting plate When in motion, the pull rod can be driven by the clutch device. Therefore, the unique clutch device in this case can make the structure manually open the cabinet door at any time when the power is cut off. When a user does not know that the cabinet door is electrically driven, and when the cabinet door is opened by mistake, the clutch device is separated, thereby avoiding damage to the electric device, so it can be widely used.
