Intelligent lock with virtual keyboard

Abstract

The invention discloses an intelligent lock with a virtual keyboard. The intelligent lock comprises a door body, an intelligent lock keyboard, a control CPU, a light sensation sensor and a virtual floating projector; reserved holes are formed in the upper side and the lower side of the inner side of the door body; the right side of the door body is connected with an intelligent lock body; the intelligent lock keyboard is arranged in the middle of the inner side of the intelligent lock body; an inner cavity is formed in the middle of the intelligent lock body; a mounting plate is fixed to the left side of the intelligent lock body; a heat dissipation pad is fixed to the middle of the left side of the intelligent lock body; and a mounting suction cup is arranged on the left side of the heatdissipation pad. The intelligent lock with the virtual keyboard is stable in performance, energy-saving, environment-friendly, flexible in combination and safer; projection imaging has a certain angle; other people cannot see the virtual numeric keyboard from the side surface, and cannot know what a password is specifically pressed down; a fingerprint cannot be left like a physical keyboard; and triggering is performed in a non-contact manner, so that the risk of cross infection of infectious diseases in the locking and unlocking process of people is reduced.

Description

technical field [0001] The invention relates to the technical field related to intelligent locks, in particular to an intelligent lock with a virtual keyboard. Background technique [0002] Smart locks are more intelligent locks in terms of user identification, security, and management, and are widely used. However, for existing smart locks, there are still some defects, such as: [0003] (1) The keyboards of the existing smart locks are all physical keyboards, which can only be triggered by pressing the password after being touched by human fingers, which has the risk of spreading diseases, and it is easy to leave fingerprints after touching, and the password is easy to be stolen by criminals; [0004] (2) The installation of the existing smart locks is not convenient enough, and the stability after installation is poor, which affects the service life of the smart locks; [0005] (3) When the smart lock is in use, it is inconvenient to dissipate the heat of the internal co...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a smart lock with a virtual keyboard to solve the above-mentioned background technology. The keyboards of the existing smart locks are all physical keyboards, which can only be triggered by pressing a password after being touched by a human finger, which has the risk of spreading diseases, and touch It is easy to leave fingerprints later, and it is easy for criminals to steal passwords. The installation of smart locks is not convenient enough, and the stability after installation is poor, which affects the service life of smart locks. It is not convenient for the heat dissipation of internal components, and the use has limitations.
