Device capable of achieving silence automatic door closing based on non-Newtonian fluid principle

Abstract

The invention relates to the technical field of smart home, and discloses a device capable of achieving silence automatic door closing based on the non-Newtonian fluid principle. A door frame and a shell are included. A fluid pipe is fixedly connected in the door frame and internally movably connected with a magnetic pole. Non-Newtonian fluid is arranged in the fluid pipe. A motor is fixedly connected in the shell. The top of the motor is fixedly connected with a bevel gear. A long rod is fixedly connected in the shell. Under the interaction of a second gear, a supporting rod, a rotation rod,a first contact point, a first spring, an electromagnet, a clamp groove, a second spring, a second contact point, a magnet, a buckle and a pull ring, a stirring rod at the outer portion of the secondgear can jack the end, in the shell, of the rotation rod, the first contact point makes contact with the second contact point under the action of the rotation rod, the electromagnet is powered on, themagnet can be attracted, under magnetic force attraction of the buckle and the clamp groove, a door can be completely closed, and accordingly the effect of automatic door closing can be achieved.

Description

Technical field [0001] The invention relates to the technical field of smart homes, in particular to a device that can realize silent and automatic door closing based on the principle of non-Newtonian fluid. Background technique [0002] Doors, entrances and exits of buildings or devices that can be opened and closed at entrances and exits, are an entity that divides a limited space and can connect and block the entrances and exits of two or more spaces. The classification of doors can be divided into the following categories, according to location: outer door, inner door; according to material: wooden door, steel door, aluminum alloy door, plastic door, iron door, aluminum wooden door, stainless steel door, glass door; according to account opening Methods are divided into: flat door, spring door, sliding door, folding door, revolving door, rolling door, ecological door. There are many types of doors, which is dazzling; therefore, a systematic understanding of the types of doors...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a device based on the principle of non-Newtonian fluid that can realize silent automatic door closing, which has the advantages of automatic door closing with time delay and noise reduction, and solves some human factors such as excessive force of the door closing person. Or the influence of some natural factors such as wind will cause the door to collide with the door frame to produce a huge noise, and the long-term collision will cause the door frame to be out of position, which will affect the use of the door.
