Power supply door lock device

Abstract

The invention relates to a power supply door lock device. In the invention, a power supply electromagnetic coil in a power supply seat generates an alternating magnetic field by utilizing external alternating power supply equipment; when a gate is closed, the alternating magnetic field acts on a power taking induction closing coil in a power taking seat; because the magnetic flux in the power taking induction closing coil changes continuously, the power taking induction closing coil produces induction current; and the induction current charges a charging circuit in an electronic door lock. Because a power taking contact panel and a power taking seat panel adopted by the invention are integrally formed by injection molding, an attractive appearance can be achieved; the power taking seat panel is thin, so the power taking electromagnetic coil on the inner side of the power taking seat panel can conveniently induce the magnetic field; the structure has the advantages of a few components, simple assembly and low cost; meanwhile, the power supply seat is also designed in the same way. Thus, compared with the conventional similar products, the device has the characteristics of compact structure, a few components, simple assembly, low cost and attractive appearance and overcomes the disadvantages such as fatigue life and the like caused by using an elastic contact key of a spring in the prior art.

Description

technical field [0001] The invention relates to the technical field of accessories related to electronic door locks, in particular to a power supply door lock device with compact structure and beautiful appearance, which adopts wireless electromagnetic induction technology to supply power to electronic door locks. Background technique [0002] With the development of locksets, more and more electronic door locks are widely used in hotels, guesthouses, families and other occasions. Existing electronic door locks are divided into electronic door locks with batteries and independent power supply and electronic door locks with external power supply lines. Although the structure of electronic door locks without batteries can be made smaller and more compact, the wires for power supply Installation is very troublesome, and the power cord needs to be wound on the door to affect the appearance. After long-term use, the power cord is easily broken due to fatigue and damage caused by ...

Problems solved by technology

Existing electronic door locks are divided into electronic door locks with batteries and independent power supply and electronic door locks with external power supply lines. Although the structure of electronic door locks without batteries can be made smaller and more compact, the wires for power supply The installation is very troublesome, and the power cord needs to be wound on the door, which affects the appearance. After long-term use, the power cord is easily broken due to fatigue and damage caused by the back and forth rotation of the door, causing failures, causing great inconvenience and safety hazards to users.

[0003] Therefore, a wireless power supply device based on the electromagnetic induction principle of an electromagnetic coil emerges at the historic moment. Most of the existing wireless power supply devices have complex structures, and their structures use spring-supported contact keys to achieve close contact. , with the aging of the spring, it is easy to have problems with the coordination; and this elastic contact key needs to be installed with a spring, which has many parts and troublesome installation, and the protruding elastic contact key affects the appearance of the product. Therefore, it is necessary to design a structure more Optimize existing structures for compact wireless power supply units
