[0031] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the utility model.

[0032] In the description of the utility model, it is understood that the orientation or position relationship indicated by the terms "center", "lateral", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side" and the like is based on the drawings attached Figure 1 The orientation or position relationship indicated by the terms "center", "lateral", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side" and the like is based on the drawings attached

[0033] In the description of the utility model, still need to explain, unless another explicit provision and limitation, term '' install '' '' link '' '' connection '' should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be direct connection, also can through intermediate medium indirectly connect.

[0034] Reference Figures 1 to 5 The utility model provides a ring shape bottom structure magnetic switch, including button 2, magnetic assembly 3, elastic component 4 and base 5,

[0035] Button 2 is movably connected with the base 5, and preferably forms a sliding connection between the button 2 and the base 5, so that the button 2 can move relative to the base 5.

[0036] The elastic component 4 is located between the button 2 and the base 5, and can be compressed when the button 2 moves towards the base 5 under pressure, and can drive the button 2 to rebound after the pressure is removed.

[0037] The magnetic assembly 3 is connected to the bottom of the button 2, and the base 5 is provided with a ring-shaped boss 53, so that the ring-shaped boss 53 is in a state of upward protrusion. When the magnetic assembly 3 is moved to the limit position by the button 2, the bottom surface of the magnetic assembly 3 can be in contact with and parallel to the top surface of the ring-shaped boss 53. Since the projection range of the magnetic assembly 3 on the horizontal plane completely surrounds the projection range of the ring-shaped boss 53 on the horizontal plane, the ring-shaped boss 53 is more inwardly contracted than the magnetic assembly 3, which facilitates the entire top surface of the ring-shaped boss 53 to form overall contact with the magnetic assembly 3, making the pressing bottom between the magnetic assembly 3 and the ring-shaped boss 53 very stable, and the sound of impact is more crisp, greatly improving the user's experience.

[0038] As an optional implementation, the button 2 is provided with a first guide 21, and the base 5 is provided with a second guide 51. When the button 2 moves towards the base 5, the first guide 21 can penetrate into the interior of the second guide 51.

[0039] The button 2 can be moved up and down in a certain direction by cooperating between the first guide 21 and the second guide 51, ensuring that the button 2 will not be stuck during movement, which helps the normal use of the product.

[0040] As an optional implementation, the interior of the second guide 51 is provided with a guide groove, which provides a moving space for the first guide 21. The bottom surface of the guide groove is provided with a ring-shaped boss 53 at the center, which is located at the center and can form better pressing contact with the magnetic assembly 3.

[0041] As an optional implementation, the magnetic component 3 is a magnet, the magnet is in a cylindrical structure, and the outer diameter of the magnet is greater than the outer diameter of the annular boss 53. In this way, the pressing experience can be further improved, and the bottom pressing is more stable, and the impact sound is more crisp.

[0042] In addition, the keyboard with such a magnetic switch is usually provided with a Hall element or other sensing device matched with the magnet, so as to realize the principle of the switch, which is a conventional prior art and thus will not be described further and is not shown in the drawings.

[0043] As an optional implementation, the bottom of the first guide 21 is provided with a containing groove, and the magnet is in interference fit with the containing groove. The interference fit can make the connection between the magnet and the first guide 21 firm and improve the stress effect.

[0044] As an optional implementation, the elastic component 4 is a spring, the spring is sleeved on the outside of the second guide 51, and the spring has good elasticity and can be elastically deformed when subjected to pressure and can rebound when the pressure is removed.

[0045] As an optional implementation, the upper cover 1 is connected with the base 5, and the connection is preferably detachable connection, so that the two are convenient to disassemble and maintain.

[0046] The upper cover 1 is provided with an opening through which the button 2 passes, and the button 2 can move up and down relative to the upper cover 1. By setting the opening, the movement of the button 2 is avoided.

[0047] As an optional implementation, the upper cover 1 is provided with a light guide mirror 11, and the light guide mirror 11 can pass through the light emitted by the light emitting component at the lower part of the keyboard. In the embodiment, the light guide mirror 11 is preferably in the shape of an upwardly protruding arc surface. In this way, the light effect is better, more dazzling, and the user's experience is further improved.

[0048] As an optional implementation, the base 5 is provided with an opening 52 at the annular boss 53, and the opening 52 is located below the center of the annular boss 53. Whether the opening 52 is provided at this position can be flexibly selected according to actual use requirements.

[0049] As an optional implementation, referring to the accompanying Figure 6 The utility model also provides a computer keyboard key, and the computer keyboard key applies the annular bottom structure magnetic switch.

[0050] As an optional implementation, referring to the accompanying Figure 7 The utility model also provides a notebook computer, and the notebook computer applies the computer keyboard key.

[0051] The above merely illustrates the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
