Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of keyboard shafts, in particular to a keyboard shaft integrating magnetism and electrostatic capacitance. Background Art
[0002] Capacitive keyboards detect key triggers through the insulating layer between two capacitor plates. Since capacitive sensors can detect tiny changes in capacitance, capacitive keyboards can achieve faster trigger responses with shorter strokes and lighter key forces. Magnetic axis keyboards use mechanical trigger switches. When a key is pressed, the magnetic reed in the keyboard will close due to the magnetic field, thereby triggering a key event. The feel and noise of a magnetic axis keyboard are similar to those of a traditional mechanical keyboard, but it is lighter than a traditional mechanical switch.
[0003] At present, capacitive keyboards use non-trigger key axes, so the key axes have a lighter touch and are softer than magnetic axis keyboards, which is suitable for long-term typing. At the same time, since there is no physical trigger, the noise is relatively small, which is an ideal choice for users who pursue a quiet environment, but its key axis has a lower feel. Magnetic axis keyboards use mechanical trigger switches, so the key axes feel more impactful and may be more suitable for users who like force, but the noise is relatively large. However, at present, keyboards are either all capacitive keyboard axes or all magnetic keyboard axes, which requires different molds to produce the keyboard axes during production, thereby increasing the production cost of the keyboard axes.
[0004] Therefore, it is particularly important to design a keyboard axis that integrates magnetism and electrostatic capacitance to solve the above-mentioned defects. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model designs a magnetic and electrostatic capacitive integrated keyboard axis, which aims to solve the technical problem that under the prior art keyboards are either all capacitive keyboard axes or all magnetic keyboard axes, which requires different molds to be used for keyboard axis production, thereby increasing the production cost of the keyboard.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] The magnetic and electrostatic capacitance integrated keyboard axis comprises a keyboard axis body and a PCB board, wherein the keyboard axis body is composed of a rebound silicone rubber, a spring, a switch handle, a magnet and a switch housing, wherein the rebound silicone rubber is mounted on the top of the PCB board, the spring is mounted inside the rebound silicone rubber, the switch handle is mounted on the top of the rebound silicone rubber, the magnet is mounted on the inner side of the bottom end of the switch handle, and the switch housing is mounted on the outer side of the switch handle.
[0008] As a preferred solution of the utility model, an electrostatic capacitor adapted for use with a spring is installed on the top of the PCB board, and a Hall switch adapted for use with a magnet is installed on the bottom of the PCB board.
[0009] As a preferred solution of the utility model, a positioning ring is fixedly connected to the outer side of the bottom end of the resilient silicone rubber, a positioning sleeve is symmetrically connected to the top of the positioning ring, a positioning column is fixedly connected to the outer side of the switch housing at a position opposite to the positioning sleeve, and a positioning hole is opened on the inner side of the positioning sleeve to match the positioning column.
[0010] As a preferred solution of the utility model, a connecting sleeve is fixedly connected to the outer side of the switch handle, the connecting sleeve is plugged into the resilient silicone rubber through a plug hole, and the magnet is installed on the inner side of the connecting sleeve through a mounting hole.
[0011] As a preferred solution of the utility model, the outer side of the switch handle is fixedly connected to a limiting sleeve, both ends of the limiting sleeve are fixedly connected to limiting blocks, and the inner side of the switch housing is provided with a limiting groove adapted for use with the limiting block.
[0012] As a preferred solution of the utility model, a positioning through hole is opened inside the switch housing, and the top end of the switch handle is slidably connected to the positioning through hole.

[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] In the utility model, through the coordinated design of the keyboard shaft and the PCB board, when the consumer uses the electrostatic capacitive keyboard, the magnet inside the keyboard shaft can be removed, so that it can respond to the spring and the electrostatic capacitor sheet when in use; when the consumer uses the magnetic keyboard, the magnet inside the keyboard shaft is retained inside, and then the magnet and the Hall switch respond after the keyboard shaft is pressed, so that the keyboard shaft only needs to produce one kind of keyboard shaft that integrates magnetism and electrostatic capacitance, and there is no need to open molds and produce them separately. The keyboard shaft can be used for two purposes, which not only reduces the cost of keyboard shaft production, but also improves the applicability of the keyboard shaft.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] Example:
[0024] See also Figure 1-Figure 5 , the utility model provides a technical solution:
[0025] The magnetic and electrostatic capacitance integrated keyboard axis includes a keyboard axis body 1 and a PCB board 2. The keyboard axis body 1 is composed of a rebound silicone rubber 3, a spring 4, a switch handle 5, a magnet 6 and a switch housing 7. The rebound silicone rubber 3 is installed on the top of the PCB board 2, the spring 4 is installed inside the rebound silicone rubber 3, the switch handle 5 is installed on the top of the rebound silicone rubber 3, the magnet 6 is installed on the inner side of the bottom end of the switch handle 5, and the switch housing 7 is installed on the outer side of the switch handle 5.
[0026] First, an electrostatic capacitor 201 adapted to be used with the spring 4 is installed on the top of the PCB board 2, and a Hall switch 202 adapted to be used with the magnet 6 is installed on the bottom of the PCB board 2. When consumers use the electrostatic capacitor keyboard, they can remove the magnet 6 on the inner side of the keyboard shaft 1, so that it can respond to the spring 4 and the electrostatic capacitor 201 when in use. When consumers use the magnetic keyboard, the magnet 6 on the inner side of the keyboard shaft 1 remains on the inside. At this time, after the keyboard shaft 1 is pressed, the magnet 6 and the Hall switch 202 respond, so that the keyboard shaft 1 only needs to produce a keyboard shaft that integrates magnetism and electrostatic capacitance, and there is no need to open molds for production separately. The keyboard shaft 1 can be used for two purposes, which not only reduces the cost of keyboard shaft production, but also improves the applicability of the keyboard shaft 1.
[0027] Furthermore, a positioning ring 301 is fixedly connected to the outer side of the bottom end of the rebound silicone rubber 3, and a positioning sleeve 302 is symmetrically connected to the top of the positioning ring 301. A positioning column 303 is fixedly connected to the outer side of the switch housing 7 at a position opposite to the positioning sleeve 302. A positioning hole 304 adapted for use with the positioning column 303 is provided on the inner side of the positioning sleeve 302. When assembling the keyboard shaft 1, the positioning column 303 on the outer side of the switch housing 7 is inserted into the positioning hole 304 in the positioning sleeve 302, so as to connect and assemble the rebound silicone rubber 3 and the switch housing 7. When the magnet 6 is disassembled, it is also convenient to separate the rebound silicone rubber 3 and the switch housing 7. After the keyboard shaft 1 is installed into the inner side of the keyboard, the positioning ring 301 presses against the PCB board 2 on the inner side of the keyboard to protect the surface of the PCB board 2.
[0028] Then, the outer side of the switch handle 5 is fixedly connected with a connecting sleeve 501, and the connecting sleeve 501 is plugged into the rebound silicone rubber 3 through the plug hole 305. The magnet 6 is installed on the inner side of the connecting sleeve 501 through the mounting hole 502. When the keyboard shaft 1 is assembled, the switch handle 5 is plugged into the plug hole 305 through the connecting sleeve 501, so that the switch handle 5 is installed on the top of the rebound silicone rubber 3, and the magnet 6 is installed in the mounting hole 502 on the inner side of the connecting sleeve 501. When the magnet 6 is disassembled, the rebound silicone rubber 3 and the switch housing 7 are separated, and then the switch handle 5 is pulled out from the top of the rebound silicone rubber 3 to expose the magnet 6 for disassembly.
[0029] Furthermore, the outer side of the switch handle 5 is fixedly connected to the limiting sleeve 503, and both ends of the limiting sleeve 503 are fixedly connected to the limiting blocks 504. The inner side of the switch housing 7 is provided with a limiting groove adapted for use with the limiting blocks 504. After the switch handle 5 is assembled, it is located on the inner side of the switch housing 7. When the consumer uses it, the keycap is pressed to press the switch handle 5, and the limiting blocks 504 slide in the limiting groove on the inner side of the switch housing 7. This not only allows the switch handle 5 to be pressed and reset stably, but also prevents the switch handle 5 from rotating after assembly, which affects the subsequent docking assembly of the keycap and the switch handle 5.
[0030] Secondly, a positioning through hole 701 is opened inside the switch housing 7, and the top end of the switch handle 5 is slidably connected to the positioning through hole 701. When the keyboard shaft 1 is assembled, the switch housing 7 is sleeved on the outside of the switch handle 5 through the positioning through hole 701. After the switch housing 7 is connected and assembled with the rebound silicone rubber 3, the top end of the switch handle 5 passes through the inner side of the positioning through hole 701, and at the same time, the key cap is also assembled with the top end of the switch handle 5 through the positioning through hole 701.
[0031] Finally, the left and right sides of the switch housing 7 are fixedly connected with buckles 702, and the switch housing 7 is connected to the keyboard through the buckles 702. When the keyboard shaft 1 is assembled and installed in the keyboard, it is clamped in the keyboard through the buckles 702, thereby facilitating the disassembly and assembly of the keyboard shaft 1 and the keyboard.
[0032] In this embodiment, the implementation scenario is specifically as follows: when assembling the keyboard shaft body 1, first put the spring 4 into the inner side of the rebound silicone rubber 3, then install the magnet 6 in the installation hole 502 on the inner side of the connecting sleeve 501, and then insert the switch handle 5 into the plug hole 305 through the connecting sleeve 501, so that the switch handle 5 is installed on the top of the rebound silicone rubber 3, and finally insert the positioning column 303 on the outer side of the switch housing 7 into the positioning hole 304 in the positioning sleeve 302, so as to connect and assemble the rebound silicone rubber 3 and the switch housing 7, thereby completing the assembly of the keyboard shaft body 1. When the keyboard shaft body 1 is assembled and installed into the keyboard, it is clamped in the keyboard through the buckle 702, and the PCB board 2 is located inside the keyboard. After the keyboard shaft body 1 is installed into the inner side of the keyboard, the positioning ring 30 1 is against the PCB board 2 to protect the surface of the PCB board 2. When the consumer uses the electrostatic capacitive keyboard, the magnet 6 on the inner side of the keyboard shaft body 1 can be removed, so that it can be used by the spring 4 and the electrostatic capacitor sheet 201 in response. When the consumer uses the magnetic keyboard, the magnet 6 on the inner side of the keyboard shaft body 1 is retained on the inner side. At this time, after the keyboard shaft body 1 is pressed, the magnet 6 and the Hall switch 202 are used in response, so that the keyboard shaft body 1 only needs to produce a keyboard shaft that integrates magnetism and electrostatic capacitance. The whole operation process is simple and convenient. Compared with the existing keyboard shaft, the utility model can be used as a magnetic keyboard shaft or a capacitive keyboard shaft through design, and can be used for both purposes. There is no need to open molds for production separately, which not only reduces the production cost of the keyboard shaft, but also improves the applicability of the keyboard shaft.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
