Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, in particular to a novel Hall enabling structure of a smart pen. Background Art

[0002] The reading pen is a new generation of intelligent reading and learning tool developed using the latest international optical image recognition technology and advanced digital voice technology. It embodies the perfect integration of electronic products and the education industry, and realizes the concept of people-oriented technology. The reading pen can simultaneously realize many functions such as point reading, repetition, follow-up reading, recording, and entertainment.

[0003] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "scan-read, point-read, and handwrite three-purpose smart pen", and its application number is "202121929600.8". The patent mainly includes a bottom shell, a top shell, and a pen head. The top shell is movably arranged on one side of the bottom shell, and a display screen is fixedly arranged inside the top shell. The bottoms of the bottom shell and the top shell are movably connected to the pen head and the pen tail cover. The bottoms of the bottom shell and the top shell are provided with a pen core and a PCB board, and a pressure sensor is provided on the PCB board; one end of the pen core passes through the pen head, and the other end is connected to the pressure sensor. The pen head is provided with a lens assembly, which is electrically connected to the PCB board; the pen head is also provided with a pen opening, which is convenient for the lens assembly to scan, point read and recognize, and handwrite recognize. After the scanning, point reading and handwriting three-purpose smart pen is turned on by a switch button, the pressure sensor is in a working state, and the picture taken by the lens assembly is sent to the MCU on the PCB board. If the MCU parses that the picture has code points, the point reading and handwriting mode will be started; if the MCU parses that the picture has no code points, the scanning and translation mode will be started, but there is a lack of protection for the pen tip, which is easily damaged by bumps.

[0004] In the prior art, the smart pen scans data through the built-in camera, and the pressure caused by writing triggers the pressure sensor; after the pressure sensor is triggered, the camera is turned on to shoot, and 4 Hall chips are installed on the camera. A magnet is installed in the pen cap, and the power is turned on and off through the Hall circuit induction; the pen cap is removed to turn on, and the pen cap is covered to turn off. Since the Hall induction has a limited range, the setting position of the Hall induction in the prior art is far away from the magnet, and even if multiple Hall detection terminals are set, the problem of insensitive switch cannot be solved; at the same time, the pen cap is easily ejected when it is bumped, causing the smart pen to automatically turn on.

[0005] To this end, we propose a "new Hall-enabled structure for a smart pen" that optimizes the magnet sensing position while ensuring that the pen cap is not easily unlocked to solve the above-mentioned problems. Utility Model Content
