An intelligent anti-collision door suction

Abstract

The invention discloses an intelligent anti-collision door stopper, which comprises a fixed plate installed on the wall and a fixed rod installed on the door body, the side wall of the fixed plate is fixedly connected with a magnetic suction seat, and the magnetic suction The seat is provided with a first backflow groove, a second backflow groove, an annular groove body and a cylindrical groove body, the first backflow groove and the second backflow groove are symmetrically distributed above the side of the cylindrical groove body, and the first backflow groove 1. A first communication cavity and a second communication cavity are respectively provided between the second return tank and the cylindrical tank body. A solenoid coil is installed in the annular tank body, and the coil coil is coaxial with the cylindrical tank body. The cylindrical tank body A permanent magnet block is arranged in the groove for sealing and sliding, and a magnetic ball is fixedly connected to the end of the fixing rod away from the door body. The invention has a simple structure, utilizes the force between the magnetic fields, can effectively avoid the collision between the fixed plate and the magnetic seat, and the greater the moving speed of the door body, the more obvious the deceleration and buffering effect, and 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.

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
