AI Technical Summary

Technical Problem

Existing fingerprint recognition modules are usually installed with screws, requiring specific tools to disassemble and assemble, and are troublesome to install. At the same time, the height of the cover is a fixed value, which cannot adapt to the recognition module sensor chip of different thicknesses, reducing practicality.

Method used

A low-cost assembled door lock fingerprint chip module is designed, using an adjustable mounting housing and fixing mechanism, electrically connected to the identification module sensor chip through wires, placing the plate and threaded rod to achieve the fixation of chips of different heights, and simplifying the installation and disassembly process through the design of cover plates and insert rods.

Benefits of technology

It realizes flexible fixation of sensor chips for different thickness identification modules, improves the practicality of the module, and reduces installation costs and labor costs by simplifying the installation process, and solves the complexity of traditional screw installation.

Abstract

The utility model relates to a low-cost assembled door lock fingerprint chip module, which belongs to the technical field of fingerprint chip modules, and comprises a circuit board body, an identification module sensor chip and a mounting shell, the circuit board body is electrically connected with one end of the identification module sensor chip through a lead, and the other end of the identification module sensor chip is electrically connected with the mounting shell; the identification module sensor chip is placed in the mounting shell, and a fixing mechanism is arranged on the upper surface of the mounting shell. According to the low-cost assembled door lock fingerprint chip module, a rotating block is rotated to drive a threaded rod to rotate in a connecting rod, and a placement plate can move up and down in a mounting shell under the action of mutual cooperation between sliding rods on the left side and sliding blocks on the right side and sliding blocks; therefore, the identification module sensor chips with different thicknesses can be fixed in the mounting shell, the number of the cooling fins is not less than two, and the cooling fins are attached to the lower surfaces of the identification module sensor chips for cooling, so that the working stability is improved.
