Description

Technical Field

[0001] This utility model relates to the technical field of electric door opening, specifically to an electric hinge and an electric door that can automatically open and close. Background Technology

[0002] Most electric door openers on the market today are derived from door closers in terms of appearance and operating principle. Whether surface-mounted or concealed with sliding rails, they still require additional hinges to complete the opening and closing action. After the door is opened, the door opener is always visible, affecting the overall appearance of the door. Most door openers with a central shaft are derived from floor springs in appearance and operating principle. Others are installed on the top of the door, with a similar working principle. This type of door opener, installed within the door leaf pivot, results in a larger gap between the door and frame, preventing the installation of a sealing step on the hinge side of the door frame and making it impossible to install a weatherstripping.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0020] like Figure 1-3 As shown, this utility model discloses an electric hinge for automatically opening and closing doors, including a lower hinge cover 15. The lower end of the lower hinge cover 15 is connected to a lower hinge base 25 via a motor fixing screw 24, and the upper end of the lower hinge cover 15 is connected to a motor 14 via a motor fixing screw 24. Specifically, the motor fixing screw 24 passes through the lower hinge base 25 and the lower hinge cover 15 in sequence and connects to the motor 14. A mounting groove 1 is formed on the lower end face of the lower hinge cover 15, and a mounting groove 2 is formed on the upper end face of the lower hinge base 25. The mounting groove 1 and the mounting groove 2 combine to form a gear mounting cavity. The cavity contains a motor starting gear 23, a relay gear 21, and an output gear 17. The middle part of the motor starting gear 23 is fixed to the motor shaft of the motor 14 by a motor shaft key pin 22. The middle part of the relay gear 21 is connected to the positioning shaft 19 by a needle roller bearing 20. The output gear 17 is connected to the lower hinge cover 15 and the lower hinge base 25 by a combined needle roller bearing 16 and a deep groove ball bearing 18. The motor starting gear 23 is connected to the output gear 17 through the relay gear 21. Specifically, the motor starting gear 23 is meshed with the relay gear 21, and the relay gear 21 is meshed with the output gear 17.

[0021] According to this utility model, an electric door is also disclosed, including a door frame 3, a door leaf 4 installed inside the door frame 3, an electric lock 6 installed on the left side of the door leaf 4, a face recognition panel 5 installed on the outer side of the door leaf 4, the face recognition panel 5 being electrically connected to a control box 10 via a communication cable 7, the control box 10 being connected to a switching power supply 8 via a power cord 9, a door leaf upper hinge 2 being connected to the upper right side of the door leaf 4 via a self-tapping screw, and a door frame upper hinge 1 being connected to the upper right side of the door frame 3 via a self-tapping screw. The door leaf upper hinge 2 is connected via... The driven shaft is rotatably connected to the upper hinge 1 of the door frame. The lower right side of the door leaf 4 is connected to the electric hinge 11 (specifically, the lower hinge base 25 is connected to the lower right side of the door leaf 4 via the self-tapping screw 26). A ground hinge seat 12 is provided below the electric hinge 11. The lower end of the rotating flat shaft of the output gear 17 is fixedly connected to the ground hinge seat 12. The ground hinge seat 12 is connected to the ground via the self-tapping screw 4. The motor plug 13 of the motor 14 is electrically connected to the control box 10.

[0022] In a specific embodiment of this application, after the motor 14 is started, the motor starting gear 23 connected to the motor shaft drives the relay gear 21 to rotate, and the rotation of the relay gear 21 drives the output gear 17 to rotate. Since the rotating flat shaft at the lower end of the output gear 17 is fixed to the ground hinge seat 12, when the motor 14 is started, it drives the door to rotate to open or close the door.

[0023] In a specific embodiment of this application, when the door 4 is closed, the face recognition panel 5 recognizes a registered face, and the electric lock 6 automatically unlocks. After unlocking, the unlocking information is transmitted to the control box 10 via the communication cable 7. The control box 10 drives the motor 14 of the electric hinge 11 to open the door. When the door opens to a certain angle, it will automatically stop. After a delay, the motor of the electric hinge 11 will drive the door to close automatically. When the door is closed, the electric lock 6 will automatically lock. Thus, one cycle of automatic door opening ends.
