Description

Technical Field

[0001] This utility model relates to the field of mechanical keyboard switch technology, specifically a mechanical keyboard switch based on a Hall sensor. Background Technology

[0002] Mechanical keyboards have a switch base on the underside of the keycaps. When the core inside the switch base is pressed down, the permanent magnet connected to the core will move downward, causing the Hall sensor at the bottom of the switch base to sense the change in magnetic field, and then output an electrical signal to execute the corresponding key operation.

[0003] Existing mechanical keyboards have a permanent magnet mounted on the center of the lower side of the switch base. The keyboard backlight is transmitted upward through a strip-shaped light-transmitting hole on the outer side of the switch base. The amount of light transmitted is small, and the markings on the keycaps cannot be effectively illuminated by the light, making it difficult to accurately locate the keyboard keys. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a mechanical keyboard switch holder based on a Hall sensor. Through the light-transmitting column set in the center of the switch holder, and the permanent magnet, through hole and transparent structure positioning cross shaft set on the side of the light-transmitting column, the backlight on the keyboard is transmitted upward through the light-transmitting column. The light shines upward through the positioning cross shaft of the transparent structure and illuminates the keycaps, so that the markings on the keycaps can be clearly illuminated, making it easy to accurately find the keys. This can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical keyboard switch base based on a Hall sensor, comprising a switch base, a light-transmitting column disposed at the center of the bottom side of the switch base, a permanent magnet disposed on one side of the light-transmitting column, a switch cover disposed on the upper side of the switch base, a magnet sleeve disposed on the lower side of the switch cover corresponding to the position of the permanent magnet, and a through hole opened on the lower side of the switch base corresponding to the position of the permanent magnet.

[0006] Furthermore, a limiting shaft is provided at the center of the shaft cover, and a positioning cross shaft is provided on the inner side of the upper end of the limiting shaft.

[0007] Furthermore, a limiting protrusion is integrally formed on the outer side of the limiting shaft, and a limiting groove is provided inside the shaft seat corresponding to the position of the limiting protrusion.

[0008] Furthermore, the shaft seat and the shaft cover are connected by a snap-fit, and the magnet sleeve is bonded to the permanent magnet.

[0009] Furthermore, a spring is provided between the light-transmitting column and the shaft cover, and the limiting shaft is connected to the shaft seat through the limiting protrusion and the limiting groove.

[0010] Furthermore, the positioning cross shaft portion is a transparent structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a light-transmitting column set in the center of the keycap, and a permanent magnet, through hole and transparent structure positioning cross axis set on the side of the light-transmitting column. The light on the keyboard is transmitted upward through the light-transmitting column, and the light shines upward through the positioning cross axis of the transparent structure onto the keycap, so that the markings on the keycap can be clearly illuminated, making it easy to accurately find the key.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This embodiment provides a technical solution: a mechanical keyboard switch base based on a Hall sensor, including a switch base 2, a light-transmitting column 5 is provided at the center of the bottom side of the switch base 2, a permanent magnet 6 is provided on one side of the light-transmitting column 5, a switch cover 1 is provided on the upper side of the switch base 2, a magnet sleeve 8 is provided on the lower side of the switch cover 1 corresponding to the position of the permanent magnet 6, and a through hole 7 is opened on the lower side of the switch base 2 corresponding to the position of the permanent magnet 6.

[0020] like Figure 1-4As shown, the lower part of the switch seat 2 is connected to the keyboard. The keycap is installed on the positioning cross-axis 4 through the cross-axis groove. When the keycap is pressed down, the limiting axis 3 slides down along the limiting groove 9 through the limiting protrusion 10, thereby causing the permanent magnet 6 inside the magnet housing 8 to move down. Through the through hole 7, the permanent magnet 6 approaches the Hall sensor, thereby changing the magnetic field of the Hall sensor, which is then converted into an electrical signal output. The light-transmitting column 5 allows the light on the keyboard to be transmitted to the positioning cross-axis 4, thereby illuminating the markings on the keycaps, making the markings on the keyboard clearly identifiable and improving the accuracy of keyboard key recognition.

[0021] A limiting shaft 3 is provided at the center of the shaft cover 1, and a positioning cross shaft 4 is provided on the inner side of the upper end of the limiting shaft 3.

[0022] The outer side of the limiting shaft 3 is integrally formed with a limiting protrusion 10, and the inside of the shaft seat 2 is provided with a limiting groove 9 corresponding to the position of the limiting protrusion 10.

[0023] The bearing seat 2 and the bearing cover 1 are connected by a snap fastener, and the magnet sleeve 8 is bonded to the permanent magnet 6.

[0024] A spring is provided between the light-transmitting column 5 and the shaft cover 1, and the limiting shaft 3 and the shaft seat 2 are connected by the limiting protrusion 10 and the limiting groove 9.

[0025] The positioning cross axis has four transparent parts.

[0026] The working principle of the mechanical keyboard switch holder based on a Hall sensor provided by this utility model is as follows: Figures 1-4 As shown, the lower part of the switch seat 2 is connected to the keyboard. The keycap is installed on the positioning cross-axis 4 through the cross-axis groove. When the keycap is pressed down, the limiting axis 3 slides down along the limiting groove 9 through the limiting protrusion 10, thereby causing the permanent magnet 6 inside the magnet housing 8 to move down. Through the through hole 7, the permanent magnet 6 approaches the Hall sensor, thereby changing the magnetic field of the Hall sensor, which is then converted into an electrical signal output. The light-transmitting column 5 allows the light on the keyboard to be transmitted to the positioning cross-axis 4, thereby illuminating the markings on the keycaps, making the markings on the keyboard clearly identifiable and improving the accuracy of keyboard key recognition.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
