Description

Technical Field

[0001] The utility model relates to the field of magnetic induction switches, in particular to a magnetic induction switch structure. Background Art

[0002] A magnetic axis keyboard is a keyboard that uses the Hall effect for triggering, which is different from traditional mechanical keyboards. The axis body of the magnetic axis keyboard adopts Hall effect technology, which can trigger keys more quickly and stably, and also has higher durability and longer service life. The magnetic axis keyboard is more suitable for environments that require efficient and quiet work due to its fast response and mute characteristics, bringing users an excellent use experience.

[0003] In the prior art, the Hall elements on the keyboard are fixed on the main control PCB board of the keyboard. Since the travel between the Hall elements on the main control PCB board of the keyboard and each keyboard switch is inconsistent, a long travel means slow response and a short travel means fast response. Therefore, it affects the keyboard use experience. Moreover, there is only one magnet in the existing magnetic induction switch structure, and some main control PCB boards of keyboards do not have Hall elements and cannot be compatible with magnetic induction switches. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a magnetic induction switch structure to solve the technical problems mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A magnetic induction switch structure includes a base, on the top of which an upper cover is installed, and an operating shaft is movably installed inside the upper cover. A magnet is arranged at the bottom of the operating shaft. A magnetic sensing module is installed at the bottom of the base. A Hall element is arranged at the bottom of the magnetic sensing module, and multiple groups of metal terminals are installed inside the magnetic sensing module. Multiple groups of limiting components are fixed at the bottom of the base.

[0006] By adopting the above technical solution, it is convenient to fix the magnetic sensor module at the bottom of the base through the setting of buckles for assembly. By setting pins, the magnetic induction switch can be fixedly connected to the main control PCB board on the keyboard during installation, so that the metal terminals on the magnetic sensor module can be in close contact with the terminals on the main control PCB board of the keyboard to improve the contact stability. When the operating shaft slides downward, it drives the magnet to approach the magnetic sensor module for magnetic induction control to output a signal. The magnetic sensor module is integrated inside the base, so that when it is installed on the keyboard, the travel of the magnet and the Hall element can be unified, and the keyboard can be compatible with the functions of both magnetic induction switches and ordinary keyboard switches.

[0007] The utility model is further set as that multiple groups of buckles are arranged at the bottom of the base.

[0008] By adopting the above technical solution, the buckle is provided to conveniently fix the magnetic sensor module at the bottom of the base for easy assembly.

[0009] The present utility model is further configured such that the limiting component includes pins fixed to the bottom of the base, and an opening is formed inside the pins, and protrusions are fixed to the outer wall of the pins.

[0010] By adopting the above technical solution, the limiting component provided can conveniently connect the base to the keyboard main control PCBA board.

[0011] The present utility model is further configured such that a spring is provided inside the base.

[0012] By adopting the above technical solution, the spring provided can conveniently reset the key shaft when pressed.

[0013] In summary, the present utility model mainly has the following beneficial effects:

[0014] The present utility model is provided with pins, a magnetic induction module, a magnet and protrusions. By providing a buckle, the magnetic sensor module can be conveniently fixed at the bottom of the base for easy assembly. By providing pins, the magnetic induction switch can be fixedly connected to the main control PCB board on the keyboard during installation, so that the metal terminals on the magnetic sensor module can be in close contact with the terminals on the main control PCB board of the keyboard to improve the contact stability. When the key shaft slides downward, it drives the magnet to approach the magnetic sensor module for magnetic induction control to output a signal. The magnetic sensor module is integrated inside the base, so that when it is installed on the keyboard, the stroke of the magnet and the Hall element can be unified, and the keyboard can be compatible with the functions of both magnetic induction switches and ordinary keyboard switches.
