Description

Technical Field

[0001] The utility model relates to the technical field of intelligent locks, in particular to a full-metal intelligent lock. Background Art

[0002] Intelligent locks are the perfect combination of computer information technology, electronic technology, mechanical technology and modern hardware technology. Fingerprint authentication has the characteristics of convenience, speed and accuracy. With the popularization of science and technology and the development of smart home, more and more people begin to choose fingerprint locks.

[0003] Ordinary fingerprint locks or password locks are both provided with two touch screens on the panel, one larger for entering the password to unlock and one smaller for fingerprint recognition. Since the materials of the touch screens generally use non-metallic materials such as glass or silicon, they need to be spliced with the metal shell of the lock, which not only has complex technology but also is prone to technological defects, and the safety performance is also poor.

[0004] In order to solve the above technical problems, the prior art such as the technical solution disclosed in Chinese Patent CN113374355A: A password lock structure, including a metal panel, a handle, a control module and a lock assembly; the handle, the control module and the lock assembly are all connected to the metal panel, a key area is provided on the metal panel, a concave cavity is provided on the back of the key area, several deformation grids are provided in the concave cavity, the control module is connected to the concave cavity, and through holes corresponding to the deformation grids are also provided on the control module; the lock assembly is electrically connected to the control module, and the handle is also connected to the lock assembly.

However, its sensitivity to metal deformation is weak, and a relatively large pressing force is required to recognize specific keys.
