Description

Technical Field

[0001] The utility model is applied to the technical field of keyboard shafts, and particularly relates to a keyboard key magnetic shaft. Background Art

[0002] Keyboards are very common input devices, often used in computers, mobile phones, industrial control equipment, processing equipment, and more. Magnetic axis keyboards are popular in esports and gaming because they can adjust the conduction stroke, allowing for quick response and a good feel. However, due to the physical properties of the magnetic field, the magnetic field at the Hall IC of the magnetic axis is weak at high strokes, reducing the accuracy of the Hall IC and making it difficult to precisely control the feel. Currently, the main method for adjusting sensitivity is to increase the magnetic field at the Hall IC by increasing the size or magnetic force of the magnet. However, larger size increases the axis weight and, with long-term use, puts greater pressure on the spring or axis, resulting in a shorter service life. If a keyboard key magnetic axis with a simple structure and clear key press feedback could be designed, and ferrite is used to enhance the magnetic field of the Hall IC during magnetic axis movement, making it easier for the Hall IC to control the trigger stroke, and a higher magnetic axis sensitivity, then this problem could be solved. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a keyboard key magnetic axis with a simple structure, obvious key press feedback, and enhanced magnetic field of the Hall IC when the magnetic axis moves by ferrite, making it easier for the Hall IC to control the trigger stroke and having higher magnetic axis sensitivity.

[0004] The technical solution adopted by the present invention is as follows: the present invention includes a key base and a shaft body, the key base includes a base upper cover and a base lower cover, the shaft body includes an axis, a magnet and a spring, an axis mounting groove is provided in the middle of the base lower cover, the axis is limitedly matched with the axis mounting groove, the spring is provided between the axis and the base lower cover, a ferrite and a Hall IC are provided at the lower end of the base lower cover, the magnet is provided on one side of the axis, and the axis drives the magnet to cooperate with the ferrite to enable the Hall IC to realize signal conversion.

[0005] Furthermore, the ferrite is arranged on the side of the lower end of the base lower cover corresponding to the magnet, and the Hall IC is arranged on the lower end of the base lower cover and close to the lower end of the ferrite, and the ferrite cooperates with the magnet and the Hall IC respectively.

[0006] Furthermore, a water drop notch buckle is provided on one side of the axis, and the magnet is limitedly engaged with the water drop notch buckle.

[0007] Furthermore, the base upper cover is provided with an axial opening, and the upper end of the axis is limitedly engaged with the axial opening.

[0008] Furthermore, a sliding shaft is provided at the lower end of the axis, a sliding channel is provided in the middle of the base lower cover, the sliding shaft and the sliding channel are slidably matched, and the axis is floatingly matched with the base lower cover through the sliding shaft, the sliding channel and the spring.

[0009] Furthermore, base buckles are provided on both sides of the base lower cover, and the base lower cover cooperates with the base upper cover through the base buckles.

[0010] The beneficial effect of the present invention is as follows: during the movement of a general magnetic axis, the distance between the magnet and the Hall IC changes from large to small, and the magnetic field at the Hall IC also changes from weak to strong. As a result, when the magnetic axis just starts to move, the magnetic field at the Hall IC is small and the amount of change in the magnetic field is small, which makes it difficult for the Hall IC to control the trigger stroke of the magnetic axis when the magnetic axis just starts to move. The present utility model patent, based on a general magnetic axis, introduces ferrite. Through the magnetic conductivity of the ferrite, the magnetic field of the Hall IC is enhanced when the magnetic axis starts to move, making it easier for the Hall IC to control the trigger stroke, thereby improving the sensitivity of the entire magnetic axis. The ferrite is arranged on the lower cover of the base and will not exert pressure on the axis center and the spring, which can ensure that the overall shaft is lightweight, has a longer service life, and has a higher sensitivity.

[0015] like Figures 1 to 4As shown, in this embodiment, the utility model includes a button base 1 and a shaft body 2, the button base 1 includes a base upper cover 3 and a base lower cover 4, the shaft body 2 includes an axis 5, a magnet 6 and a spring 7, the middle of the base lower cover 4 is provided with an axis mounting groove 8, the axis 5 is limitedly matched with the axis mounting groove 8, the spring 7 is arranged between the axis 5 and the base lower cover 4, the lower end of the base lower cover 4 is provided with a ferrite 9 and a Hall IC 10, the magnet 6 is arranged on one side of the axis 5, the axis 5 drives the magnet 6 to cooperate with the ferrite 9 to enable the Hall IC 10 to realize signal conversion. It can be seen that the axis 5 is installed between the base upper cover 3 and the base base 4, and the spring 7 is installed between the axis 5 and the base bottom cover 4. The spring 7 provides elastic force for the axis 5 to improve the feel of the magnetic axis. According to the magnetic permeability of the ferrite 9, the ferrite is installed near the Hall IC10 to enhance the magnetic field strength at the Hall IC10, so that the change in the magnetic field strength of the Hall IC10 is more obvious, thereby improving the sensitivity of the magnetic axis.

[0016] like Figure 1 and Figure 2 As shown, in this embodiment, the ferrite 9 is arranged on the side of the lower end of the base lower cover 4 corresponding to the magnet 6, and the Hall IC 10 is arranged on the lower end of the base lower cover 4 and close to the lower end of the ferrite 9. The ferrite 9 cooperates with the magnet 6 and the Hall IC 10 respectively. As can be seen, the ferrite 9 is arranged on the same side as the magnet 6 and the Hall IC 10 is close to the lower end of the ferrite 9, so that the magnetic conductivity of the ferrite is more fully exerted.

[0017] like Figure 2 and Figure 3 As shown, in this embodiment, a water drop notch buckle 11 is provided on one side of the axis 5, and the magnet 6 is limitedly engaged with the water drop notch buckle 11. It can be seen that the axis 5 has a water drop notch buckle 11, and the water drop notch buckle 11 is used to install and fix the magnet 6, so that the magnet 6 is fixed on the axis.

[0018] like Figure 2 As shown, in this embodiment, the base cover 3 is provided with an axis opening 12, and the upper end of the axis 5 is limitedly engaged with the axis opening 12. It can be seen that the axis opening 12 can provide space for the axis 5 to move up and down and can limit the movement range of the axis 5.

[0019] like Figure 1 and Figure 2As shown, in this embodiment, a sliding shaft 13 is provided at the lower end of the shaft 5, and a sliding channel 14 is provided in the middle of the base lower cover 4. The sliding shaft 13 and the sliding channel 14 are in sliding engagement with each other, and the shaft 5 is in floating engagement with the base lower cover 4 through the sliding shaft 13, the sliding channel 14, and the spring 7. Thus, it can be seen that the sliding shaft 13 and the sliding channel 14 are adapted to fix the direction of up and down movement, and the spring 7 provides a restoring force and a floating feel.

[0020] like Figure 2 As shown, in this embodiment, base buckles 15 are provided on both sides of the base lower cover 4, and the base lower cover 4 is matched with the base upper cover 3 through the base buckles 15. It can be seen that the base buckles 15 can assemble the base upper cover 3 and the base lower cover 4 into a whole, and can also be unlocked and disassembled to facilitate component replacement.

[0021] The working principle of the present invention is as follows: when a key needs to be triggered, the axis 5 is pressed down, the magnet 6 descends, the ferrite 9 is attracted and cooperated with the magnet 6, the magnetic attraction force changes, and the magnetic force change is transmitted to the top of the Hall IC 10 through the magnetic conductivity of the ferrite 9. The Hall IC 10 senses the magnetic force change, and the Hall IC 10 triggers the stroke to trigger the key, thereby achieving high-sensitivity pressing of the magnetic axis key position.

[0022] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
