Abstract

This design is for automatically opening and closing the reinforcement door using a conventional hydraulic hinge, and consists of a motor, a clutch, and a position sensor instead of a spring and a hydraulic device.

For this purpose, the position sensor for measuring the rotation angle of the motor 6 and the worm gear 3 with the reduction gear 5, the clutch disk 11 connected to the gear, the clutch disk 12 connected to the rotation shaft 1, and the door- It consists of a slit disc 8 and a photo coupler 7.

Due to this disc clutch, it is safe for collision with the human body during opening and closing, and does not transmit excessive force to the device.

Description

Auto Door Hinge {Auto Door Hinge}

Existing manual reinforcement door uses spring and hydraulic device in hinge to close automatically, so strong force is needed to open it and lubricating oil is inserted between cylinder and piston to control spring restoring force.

Existing reinforced doors can be fixed and opened only at 90 and 115 degrees.

In addition, the existing hydraulic reinforcement doors need to be replaced and repaired frequently because the air is introduced into the room due to the gap between the door and the door or the frame surface due to the spring's relaxation or the hydraulic leakage.

This design takes the form of the hydraulic hinge of the reinforcement door and converts the interior from the spring, hydraulic to the automatic opening and closing. More specifically, the hinge consisting of the existing spring and the hydraulic device is replaced with the motor, clutch and position instead of the spring. The sensor was used to open and close automatically.

Therefore, this design eliminates the inconvenience of using the reinforcement door and configures the same shape as the existing hydraulic hinge, so that the hydraulic hinge installed in the reinforcement door can be easily replaced with the automatic hinge.

In order to achieve the above object, the present invention has the same external shape as a conventional hydraulic hinge device, and has a clutch disc 11 and a rotating shaft connected to a motor 6 and a worm gear 3 having a reduction gear therein instead of a hydraulic device. It is composed of (position sensor-slit disc and photocoupler) for measuring the rotation angle of the connected clutch disk 12 door, and is an automatic opening and closing device of the reinforcement door composed of a controller for driving control of the motor and a position sensor and interlocking control. .

In the present invention, in order to control the force (torque) and speed for automatically opening and closing the reinforcement door, a reduction gear (5) was installed in the motor (6). A worm gear 3 was used between the reduction gear 5 and the clutch disk 11 of the motor to transmit to (1).

The clutch disk 11 and the clutch disk 12 are configured to mitigate the impact when colliding with the user during the automatic opening and closing of the reinforcement door and to smoothly operate automatically and manually even when the user opens or closes the hands during operation. It was.

Permanent magnets 9 were inserted between the clutch disc 11 and the disc 12 to maximize the friction force of the motor in order to sufficiently transfer the rotational force of the motor to the axis of rotation while minimizing wear between the clutch discs.

Position sensor-slit disk (8) and photo coupler (7)-rotated by the gear (15) above the clutch disc (12) connected to the rotating shaft (1) to determine the open and closed angles of the reinforcement door. Was constructed. In addition, there is a controller for controlling the driving speed of the motor and the position sensor, and the direction and position of the automatic opening / closing are controlled by controlling the rotation direction and speed of the motor in the control according to the signal input by the sensor installed in the door of the reinforcement door. Control.

According to this design, in the existing reinforcement door, simply replace the lower hydraulic hinge with the same automatic hinge to convert the reinforcement door into an electric automatic door to make the passengers comfortable, and it is possible to use both automatic and manual to prevent accidents of the passengers. Automatic control of the door is possible.

Existing manual reinforcement doors use springs and hydraulic devices on the hinges to automatically close, so not only the elderly or children need to use the power to open the door, but also the strongness of the doors by the spring when several people enter the door. Resilience may cause injuries to future people, especially for the elderly and children. In addition, even when carrying a baggage in both hands or pushing a stroller or cart, it is safe and convenient to access.

In addition, the existing reinforcement door can be fixed and opened only at 90 degrees, 115 degrees, but this design can be opened at any angle desired by the user at the same time as the automatic opening and closing of the door.

Existing hydraulic reinforcement doors need to be replaced and repaired frequently due to the gap between door and door or frame surface due to spring loosening or lack of hydraulic pressure. It is closed by position sensor irrespective of the need for maintenance.

In order to replace the existing reinforced doors with sliding automatic doors, not only space constraints but also the entire door and frame must be replaced, resulting in time and financial constraints.

This design is simple because the hydraulic hinge of the existing reinforcement door can be replaced with the automatic hinge, so it can be used manually in case of power failure and can be installed at a relatively low cost compared to the sliding type.
