Intelligent anti-collision door stopper

Abstract

The invention discloses an intelligent anti-collision door stopper. The intelligent anti-collision door stopper comprises a fixed plate installed on the wall surface, and a fixed rod installed on a door body, a magnetic suction seat is fixedly connected to the side wall of the fixed plate, a first reflux groove, a second reflux groove, an annular groove body and a cylindrical groove body are formed in the magnetic suction seat, the first reflux groove and the second reflux groove are symmetrically distributed on the side upper part of the cylindrical groove body, a first communicating cavity and a second communicating cavity are correspondingly formed between the first reflux groove, the second reflux groove and the cylindrical groove body, a solenoid coil is installed in the annular groove body, the solenoid coil is coaxial with the cylindrical groove body, a permanent magnetic block is slidably arranged in the cylindrical groove body in a sealed mode, and a magnetic ball is fixedly connected to the end, away from the door body, of the fixed rod. According to the intelligent anti-collision door stopper, the structure is simple, the collision between the fixed plate and the magnetic suction seat can be effectively avoided by using the force between magnetic fields, the greater the moving speed of the door body is, the more obvious the deceleration and buffering effect is, and the intelligent anti-collision door stopper is suitable for different use environments.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to an intelligent anti-collision door stopper. Background technique [0002] The anti-collision door stopper is a component installed on the door body and the wall or on the ground to prevent the door body from colliding with the wall. When people push the door quickly, the anti-collision door stopper can prevent the door body from directly colliding with the wall, thereby damaging the door body and the wall. play a protective role. [0003] Common anti-collision door stoppers are usually a combination of metal balls and permanent magnets. The door body is fixed by the attraction of the permanent magnets to the metal ball. Because people sometimes use too much force when pushing the door, the anti-collision door stopper After long-term use, there will be structural damage due to multiple collisions between the permanent magnet block and the metal ball. Some new anti-collision do...

Problems solved by technology

[0003] Common anti-collision door stoppers are usually a combination of metal balls and permanent magnets. The door is fixed by the attraction of the permanent magnets to the metal ball. Because people sometimes use too much force when pushing the door, the anti-collision door stopper After long-term use, there will be structural damage due to multiple collisions between the permanent magnet block and the metal ball. Some new anti-collision door stoppers are provided with a magnetic ring that repels the permanent magnet block fixed on the wall outside the metal ball. , to slow down the collision between the metal ball and the permanent magnet block, if the magnetic force of the additional magnetic ring is too large, the magnetic ring and the permanent magnetic block will repel each other, and the door stopper cannot play the role of fixing the door body; if the magnetic force of the additional magnetic ring is small , when people push the door hard, the metal ball will still collide with the permanent magnet block, and if things go on like this, the structure of the door stopper will still be damaged
