Electromagnetic lock device, storage cabinet and takeaway box

Abstract

The application provides an electromagnetic lock device, including: a weak magnet, a strong magnet, and a threshold unit arranged on the first bearing plate and / or the second bearing plate; the weak magnet has the function of making the first bearing plate and the second bearing plate absorb The first adsorption force of the threshold unit; when the first bearing plate and the second bearing plate are in the adsorption state, the strong magnet cannot be powered; when the first bearing plate and the second bearing When the magnet is electrified, the strong magnet generates a second adsorption force that makes the first bearing plate and the second bearing plate absorb; the second adsorption force is stronger than the first adsorption force. The electromagnetic lock device provided by the present application can realize the opening and locking of the door only by setting the weak magnet, the strong magnet and the threshold unit, which simplifies the complexity of the existing electronic lock and also reduces the frequency of failure of the electronic lock. In addition, the strong magnet only works when the door is opened without authorization, which reduces the power consumption of the electronic lock, thereby reducing the cost of using the electronic lock.

Description

technical field [0001] The present application relates to the field of door locks, in particular to an electromagnetic lock device, a storage cabinet, and a takeaway box. Background technique [0002] With the rapid development of science and technology, the application of electronic locks has gradually spread to all walks of life. For example, in the takeaway transportation industry and the express delivery industry, electronic locks are applied to takeaway boxes and parcel storage cabinets, which are used to lock the takeaway boxes and the storage cabinets respectively. Most of the existing electronic locks are composed of electronic control modules and mechanical moving parts, that is, the action of opening and locking the door requires the cooperation of the electronic control module and the mechanical moving parts to complete. [0003] However, based on the complex structure of mechanical moving parts, failures often occur, which makes the electronic lock unable to wor...
