Description

Technical Field

[0001] This utility model relates to the field of keyboard switch technology, and specifically discloses a keyboard key with good stability. Background Technology

[0002] With the rapid development of computer keyboard technology, magnetic induction keys are becoming increasingly popular among computer gamers and have been successfully applied to keyboards. Magnetic induction keys include a vertically pressable key shaft and a housing that supports the vertical movement of the key shaft. A magnet is installed on the key shaft, and a Hall switch is installed in the housing. The magnetic induction key moves the magnet up and down by vertically pressing the key shaft. By changing the distance between the magnet and the Hall switch, the signal change of the Hall switch is sensed, thus realizing the function of the magnetic induction key.

[0003] In existing magnetic induction buttons, a downward-facing mounting groove is usually set at the bottom of the button shaft. The magnet is inserted into the mounting groove through the opening. To prevent the magnet from falling out, the magnet and the mounting groove are usually assembled with an interference fit. This installation method can easily cause the mounting groove to be squeezed and deformed, causing the magnet to shift in position within the mounting groove. This affects the stability of the magnetic induction during button use and can also easily lead to the magnet loosening and falling off, affecting the lifespan of the button. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a keyboard key with good stability, which can avoid magnet displacement caused by compression deformation and improve the stability of magnetic induction during key use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stable keyboard key includes a base with a top cover fastened to it. The top of the top cover has an opening, and the base and top cover, when fastened together, form a receiving cavity. A key shaft and an elastic reset mechanism for resetting the key shaft upwards are disposed within the receiving cavity. The upper part of the key shaft protrudes from the opening at the top of the top cover. The key shaft has a downwardly extending limiting post, and the limiting post has a downward-opening mounting groove. A magnetic element is disposed within the mounting groove, and the periphery of the magnetic element maintains a distance from the inner wall of the mounting groove. A cover is provided at the lower opening of the mounting groove, and the lower end of the magnetic element abuts against the cover. By providing a cover at the opening of the mounting groove, an interference fit is not required when installing the magnetic element, avoiding deformation of the mounting groove that could cause displacement of the magnetic element, thereby improving the stability of the magnetic induction signal during key use.

[0007] As a preferred technical solution, the distance between the periphery of the magnetic element and the inner wall of the mounting groove is 0 to 0.2 mm.

[0008] As a preferred technical solution, the cover is provided with a connecting part, and the opening of the mounting groove is provided with a connecting groove corresponding to the connecting part.

[0033] First, please refer to Figure 1-4As shown, an embodiment of the present invention provides a keyboard key with good stability, including a base 10, on which a top cover 20 is fastened. The top of the top cover 20 has an opening. After the base 10 and the top cover 20 are fastened together, they form a receiving cavity 30. The receiving cavity 30 contains a key shaft 40 and an elastic reset mechanism (not shown) for resetting the key shaft 40 upward. The upper end of the key shaft 40 has a cross-shaped connecting post 48, which protrudes from the opening at the top of the top cover 20. The key shaft 40 has a downwardly extending limiting post 41. The base 10 has a limiting sleeve 11 corresponding to the limiting post 41, and the limiting post 41 is slidably disposed within the limiting sleeve 11. The limiting post 41 has a downward-opening mounting groove 42, in which a magnetic element 43 is disposed. A cover 44 is provided at the lower opening of the mounting groove 42, and the lower end of the magnetic element 43 abuts against the cover 44. A gap is maintained between the periphery of the magnetic element 43 and the inner wall of the mounting groove 42, and the gap is 0–0.2 mm. In this invention, the limiting sleeve 11 is open at the upper end and closed at the lower end. In actual use, a Hall switch can be installed inside the limiting sleeve 11. When the limiting post 41 moves up and down within the limiting sleeve 11, a signal change is generated.

[0034] This invention provides a cover 44 at the opening of the mounting groove 42, thereby eliminating the need for an interference fit when installing the magnetic element 43. This prevents the mounting groove 42 from being squeezed and deformed, which could lead to displacement of the magnetic element 43, thus improving the stability of the magnetic induction signal during button use.

[0035] Specifically, the cover 44 is provided with a connecting part 45, and the opening of the mounting groove 42 is provided with a connecting groove 46 corresponding to the connecting part 45. During assembly, the cover 44 is fixed to the opening of the mounting groove 42 by being engaged in the connecting groove 46 through the connecting part 45. In this utility model, the connecting part 45 is provided on the edge of the cover 44, and the connecting part 45 protrudes upward in an arc shape. The connecting groove 46 penetrates the inner and outer sides and the lower side of the sidewall of the mounting groove 42. During assembly, the cover 44 is embedded in the inner side of the lower opening of the mounting groove 42, and the connecting part 45 engages with the connecting groove 46 upward. To avoid the connecting part 45 affecting the movement of the limiting post 41, the outer surface of the connecting part 45 is located inside the connecting groove 46 or flush with the peripheral surface of the limiting post 41. It should be understood that in actual use, the connecting groove 46 can also be provided on the inner sidewall of the mounting groove 42, and the connecting part 45 engages with the connecting groove 46 from the inner side of the mounting groove 42.

[0036] Specifically, the sidewall of the receiving cavity 30 forms a limiting slide 31, and the outer side of the key shaft 40 forms a protrusion 47 corresponding to the limiting slide 31, the protrusion 47 being slidably connected to the limiting slide 31. The upper cover 20 is provided with a downwardly extending first hook 21, the first hook 21 being disposed inward, and the base 10 is provided with a first slot 12 corresponding to the first hook 21. The upper cover 20 is hooked into the first slot 12 by the first hook 21 and fastened to the base 10. To facilitate the installation of the key on the keyboard, the lower edge of the upper cover 20 is also provided with a downwardly extending second hook 22, the second hook 22 being disposed outward, and the periphery of the base 10 is provided with a relief groove 13 corresponding to the second hook 22. During assembly, the second hook 22 is embedded in the relief groove 13 from top to bottom.

[0037] like Figure 5 As shown, in actual use, a surrounding plate 49 can also be provided on the outside of the cross connecting post 48 on the key shaft 40. The surrounding plate 49 surrounds the cross connecting post 48. During assembly, the surrounding plate 49 and the cross connecting post 48 are exposed at the opening at the top of the cover 20.

[0038] In summary, this utility model, by setting a cover at the opening of the mounting slot, eliminates the need for an interference fit when installing magnetic components, preventing the mounting slot from being squeezed and deformed, which could lead to displacement of the magnetic components and thus improving the stability of the magnetic induction signal during button use. Simultaneously, the cover also prevents the magnetic components from falling out of the mounting slot. Since the lower end of the magnetic component abuts against the cover, a properly designed mounting slot depth also ensures that the magnetic components remain secure within the slot, preventing any abnormal noises caused by loosening.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
