Novel door opener and control circuit thereof

Abstract

The novel door opener comprises a shell, a push-pull rod, a screw rod, a driving mechanism and a limiting mechanism are arranged in the shell, the screw rod is in threaded connection with the push-pull rod, the driving mechanism is used for driving the screw rod to rotate, a telescopic opening is formed in the left end of the shell, and the push-pull rod is matched with the telescopic opening; the limiting mechanism comprises a mechanical switch, a Hall sensor, a magnet, a fluted disc and a limiting mounting shell, the limiting mounting shell is mounted in the shell, the mechanical switch and the Hall sensor are arranged in the limiting mounting shell, the Hall sensor is mounted at the right end of the mechanical switch, the fluted disc is mounted on the screw and corresponds to the front of the Hall sensor, and the magnet is arranged in the limiting mounting shell. The magnet is installed on the limiting installation shell and corresponds to the rear portion of the Hall sensor. According to the novel door opener and the control circuit thereof, the Hall sensor and the mechanical switch are combined in series, accurate positioning can be achieved, damage to the motor can be avoided without arranging a check block, and potential safety hazards can also be reduced.

Description

technical field [0001] The invention belongs to the field of door opener devices, and in particular relates to a novel door opener and a control circuit thereof. Background technique [0002] In the use of the swing door operator, the opening and closing positions of the door body need to be limited by a specific limit mechanism. There are currently two options in the industry: [0003] One solution is to use the trigger signal of a mechanical switch. By adjusting the position of the mechanical switch installed inside the door opener, it provides the door opener controller with a stop signal to open and close the door. Due to the installation structure of this solution, the adjustment of the position of the mechanical switch inside the door opener will cause a great deviation in the positioning of the door opening and closing, and it is difficult to achieve accurate positioning. It needs to be adjusted several times during installation. Installation and use bring some tro...
