detailed description

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Combining Figures 1 to 6, an Internet-based intelligent safety door closing device includes a vibration sensor 1, a single-chip microcomputer 2, a wireless module 3, a gear set 4, a visual signal processor 5, a battery 6, a motor 7, a camera 8, and a limit Switch 9, shell 10, rotating rod 11, indicator light group 12 and connecting rod 13.

Shake sensor 1, single-chip microcomputer 2, wireless module 3, gear set 4, visual signal processor 5, battery 6, motor 7, limit switch 9 are all arranged in the shell 10, and the shell 10 is fixed on the door frame, and one end of the rotating rod 11 It is rotatably connected with the door, and the other end extends into the casing 10 to connect with the gear set 4. The motor 7 is set on the top surface of the gear set 4, and its output shaft is fixedly connected with the gear set 4. The limit switch 9 is set on the gear set 4, and the door is closed. , the limit switch 9 is in contact with the connecting rod 13, the camera 8 is fixed on the casing 10, and the situation outside the door is photographed, and the indicator light group 12 is arranged on the casing 10. When the motor 7 rotates, the torque of the rotation is increased by the deceleration effect of the gear set 4, thereby driving the rotating rod 11 to rotate to realize closing and opening the door.

The single-chip microcomputer 2 is respectively connected with the wireless module 3, the motor 7, the camera 8, the limit switch 9, the shake sensor 1, the visual signal processor 5, the indicator light group 12, and the storage battery 6 through wires.

The visual signal processor 5 is used for receiving and processing the signal of the camera 8 .

Storage battery 6 is connected with single-chip microcomputer.

Gear set 4 The gear set 4 includes four sets of gears meshing in sequence to increase the torque, wherein the first set is provided with a limit switch 9, the second set is connected with the rotating rod 11, and the third set is fixedly connected with the motor 7

When the door of the user's house is opened, the limit switch 9 therein can distinguish the opening and closing situation of the door, thereby sending this situation to the mobile phone of the user through the wireless module 3 .

The user can receive the information collected by the camera 8 through the mobile phone, observe the situation at the door, and decide the next step. If the door needs to be closed, the user can realize closing the door through the reverse rotation of the motor 7 in the mobile phone control device.
