Description

Technical Field

[0001] This utility model relates to the field of keyboard key axis technology, specifically a keyboard pin-fixed magnetic axis structure. Background Technology

[0002] A key switch is the individual switch under each key on a mechanical keyboard, also known as a mechanical switch. It is the core component of a mechanical keyboard, responsible for key actuation and tactile feedback. There are various types of mechanical switches, including black, blue, brown, and red switches, each with different feel, sound, and suitable applications. The working principle of a keyboard magnetic switch is mainly based on three stages: magnetic field sensing, actuation, and return.

[0003] A search revealed that patent application number CN202420283415.3 discloses a magnetic axis keyboard structure. The axis includes a switch housing, a spring, a key slidably connected to the switch housing, and a switch PCB board fixed to the switch housing. The spring connects the key to the inner bottom wall of the switch housing. A magnet is fixed on the key. A Hall effect sensor is provided on the switch PCB board. A prompting device is provided inside the keyboard housing. Both the Hall effect sensor and the prompting device are connected to the main PCB board. Using this invention results in improved tactile feedback. By setting different contrast values ​​on the main PCB board, the prompting device is activated after the key is pressed for different distances, allowing for various tactile settings and precise adjustment of different keyboard feel, with improved overall tactile feedback.

[0004] Currently, ordinary keyboard magnetic switches lack positioning pins and rely on the keyboard panel for positioning. Therefore, screw posts are added to the panel to fix the PCB, ensuring a tight connection between the PCB, magnetic switch, and panel. However, screws used in this method cannot be fully tightened, often resulting in partial separation, especially when the press deviates from the screw position, causing inaccurate triggering and frequent asynchronous responses. Furthermore, the copper leads of ordinary mechanical switches are relatively soft and easily bent. During assembly, these copper leads can easily deviate from the lead holes and bend under the switch body, leading to functional loss and rework. Therefore, we need to propose a keyboard magnetic switch structure with fixed pins. Utility Model Content

[0005] The purpose of this invention is to provide a keyboard pin-fixed magnetic shaft structure. With the fixed pin design, screws are not needed to fix the PCB board, magnetic shaft and keyboard panel. The pins of the shaft are used for fixing, which can better reduce material costs. The fixed pin is made of nickel-plated iron, which is harder than the copper pins of ordinary machinery and is not easy to bend. This can improve the problem that copper pins are easy to bend and cause the pins to deviate from the pin holes and bend under the shaft during assembly, thus solving the problems mentioned in the background art.

[0008] The base has triangular positioning elements on two non-adjacent sides, which abut against the edge of the positioning hole.

[0009] The upper cover is provided with a through hole, and the shaft is movably installed inside the through hole.

[0012] One end of the spring is connected to the shaft core, and the other end of the spring is connected to the inner wall of the base.

[0013] The conductive sheet includes a moving sheet and a stationary sheet. The stationary sheet is fixed on the base, the top of the moving sheet is connected to the shaft core, and the fixed pin is integrally formed and set at the bottom of the moving sheet.

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a keyboard pin-fixed magnetic shaft structure, including a magnetic shaft body 1 mounted on a sound-absorbing cotton plate. The magnetic shaft body 1 includes an upper cover 11 and a base 16 that are snapped together. A shaft core 12 for connecting keycaps and automatically resetting is movably mounted on the upper cover 11. The upper cover 11 is made of PC material, the base 16 is made of PA66 material, and the shaft core 12 is made of POM material. It should be noted that a permanent magnet is also provided inside the shaft core 12.

[0027] The bottom of the base 16 is connected to a limiting post 18 for positioning the magnetic shaft body 1. The end of the limiting post 18 is frustum-shaped, and the outer wall of the limiting post 18 is provided with a positioning strip. One end of the positioning strip is beveled to increase the positioning effect of the magnetic shaft body 1. A conductive sheet and a spring are installed between the top cover 11 and the base 16. The conductive sheet is integrally formed with a fixing pin 19 that connects to the PCB board and is used to fix the PCB board, the magnetic shaft body 1, and the keyboard panel.

[0028] There are at least two (multiples of two) fixed pins 19. Two fixed pins 19 can be used as a circuit jumper, reducing the difficulty of routing in PCB design.

[0029] The magnetic shaft body 1 of this application does not require screws to fix the PCB, magnetic shaft and panel. It can be directly fixed by fixed pins 19, which reduces material costs and saves the material costs of screws and screw posts, as well as the time cost of installing screws.

[0030] Optionally, a copper sleeve is installed on the fixed pin 19 to enable the single magnetic shaft body 1 to be plugged in and replaced.

[0031] The fixed pin 19 is made of nickel-plated iron, which is harder than the copper pins of ordinary machinery and is not easily bent. This improves the problem that copper pins are easy to bend, causing the pins to deviate from the pin holes and bend under the shaft during assembly.

[0032] The sound-absorbing cotton plate has a positioning hole, through which the magnetic shaft body 1 passes and is fixed inside the positioning hole.

[0033] Triangular positioning elements 17 are provided on two non-adjacent sides of the base 16. The positioning elements 17 abut against the edge of the positioning hole to limit the base 16 to the bottom of the sound-absorbing cotton board.

[0034] The top cover 11 is provided with a through hole 15, and the spindle core 12 is movably installed inside the through hole 15. Under the action of the spring, the spindle core 12 can move up and down. When the spindle core 12 (i.e. the keycap) is pressed, the spindle core 12 moves downward to realize the input of the command. When the keycap is released, the spindle core 12 moves upward to reset under the action of the spring force.

[0035] The upper cover 11 has upper locking parts 14 on two non-adjacent sides, and the base 16 has lower locking parts 110 on the other two non-adjacent sides. The upper locking parts 14 and the lower locking parts 110 are fastened together to facilitate the connection between the upper cover 11 and the base 16.

[0036] The top cover 11 has flanges 13 at each of its four corners. The flanges 13 abut against the edge of the positioning hole and are used to limit the top cover 11 to the top surface of the sound-absorbing cotton board.

[0037] One end of the spring is connected to the shaft core 12, and the other end of the spring is connected to the inner wall of the base 16. The spring is located at the center of the magnetic shaft body 1.

[0038] The conductive sheet includes a moving sheet and a stationary sheet. The stationary sheet is fixed on the base 16, the top of the moving sheet is connected to the shaft core 12, and the fixed pin 19 is integrally formed and set at the bottom of the moving sheet.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
