Description

Technical Field

[0001] This utility model relates to the field of keyboards, specifically to a mute key and a mute keyboard. Background Technology

[0002] With the rapid development of information technology and electronic devices, various keyboards have been widely used in office equipment, consumer electronics, industrial control, and other fields. Traditional keyboards mainly achieve input functions through the mechanical structure of the keys. However, in actual use, due to the large mechanical contact and collision during the pressing and releasing of the keys, noticeable noise is easily generated. Especially when used in quiet environments, this can easily cause auditory interference to users and affect their user experience.

[0003] To address the aforementioned issues, existing technologies have proposed several silent key structure solutions. These include optimizing the connection structure between the keycap and key base, adding cushioning components to contact areas, or using flexible materials for sound absorption and noise reduction. However, existing silent key structures still have the following shortcomings: First, their noise reduction effect is limited, especially in controlling noise during key rebound. Second, their complex structure or demanding manufacturing processes lead to high production costs, making them difficult to widely apply in low- to medium-cost products. Third, the design of the cushioning and positioning structures often fails to balance silent operation with consistent key feel, affecting the overall product performance. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a silent button and a silent keyboard, featuring a reasonable structure, significant noise reduction effect, and a silent button structure that balances cost and tactile feedback, thus overcoming the shortcomings of existing technologies.

[0005] This utility model is achieved through the following technical solution: a mute button, comprising:

[0006] One or more keycaps, each keycap having a key switch at its bottom, the keycaps being mounted on a key socket via the key switches;

[0007] The key shaft has elastic connecting sections on both sides. Each elastic connecting section has a locking hook on its bottom outer side. The locking hook has a hollow cavity inside, which allows the locking hook to elastically deform.

[0008] A filler is provided inside the hollow cavity to absorb some of the noise generated by the reciprocating motion of the keycaps.

[0009] A buffer positioning mechanism is provided at the contact position between the keycap and the key base to reduce impact noise when the keycap is pressed down.

[0010] As a preferred technical solution, the buffer positioning mechanism includes a conical protrusion disposed on the upper end of the key seat, and a conical buffer portion disposed on the lower end face of the keycap corresponding to the conical protrusion, wherein the conical buffer portion is provided with a conical positioning groove.

[0011] As a preferred technical solution, both the conical protrusion and the conical buffer portion are made of elastic rubber material.

[0012] As a preferred technical solution, both the front and rear ends of the locking hook are open, and the filling material is made of honeycomb cotton to absorb some of the impact noise.

[0013] As a preferred technical solution, two longitudinally arranged slots are opened on both sides of the key shaft, and the elastic connecting section is formed in the middle through the slots on both sides.

[0014] As a preferred technical solution, the inner side of the key seat is provided with a limiting step surface corresponding to the position of each locking hook.

[0015] As a preferred technical solution, the upper surface of the locking hook is an inclined contact surface, and the limiting step surface and the upper surface of the locking hook are in line contact.

[0016] This utility model discloses a silent keyboard, which includes one or more mute keys.

[0017] The beneficial effects of this utility model are: by setting locking hooks with elastic deformation capability on both sides of the key shaft and forming a hollow cavity inside the locking hooks, and further filling it with honeycomb cotton material with sound absorption properties, this utility model can effectively absorb some of the impact noise generated during the key pressing and rebound process, thereby reducing the overall operating noise of the key, and making it easier to remove the keycaps, reducing the squeezing force when removing the keycaps, and reducing the wear of the locking hook position.

[0018] The buffer positioning mechanism of this utility model, located at the contact position between the keycap and the key base, adopts a conical structure design and is combined with elastic rubber material. It not only provides a good buffering effect, but also enhances the positioning stability after the key is pressed down, and improves the feedback feel during use.

[0019] The key shaft of this invention forms an elastic connecting section through longitudinal slots on both sides, which, together with the locking hook and the limiting step surface in the key seat, achieves stable installation. Furthermore, the locking hook and the limiting step have a line contact inclined surface structure, which reduces the impact area and lowers noise. Attached Figure Description

[0025] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0026] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0027] like Figure 1 and Figure 2 As shown, the present invention proposes a silent button with a reasonable structural design that can effectively reduce noise during operation while maintaining a good button feel. The following describes the implementation of the present invention in detail with reference to the accompanying drawings and specific structure.

[0028] In practical implementation, the mute button includes one or more keycaps 2, each keycap 2 having a key shaft 22 at its bottom. The keycap 2 is mounted on the key socket 28 via the key shaft 22. The keycap 2 is a common key shell component, with a key shaft 22 portion at its lower end that can be inserted into the key socket 28. The key shaft 22 forms a vertically movable connection structure by inserting into the key socket 28, realizing the rebound and pressing action of the keycap 2.

[0029] To enhance the connection flexibility and noise reduction of the key shaft 22, elastic connection sections 27 are formed on both sides of the key shaft 22. Specifically, longitudinally arranged slots are provided on both sides of the key shaft 22, and the slots penetrate the key shaft 22 to a certain depth, so that the part located between the two sides forms a connection section with elastic deformation capability.

[0030] Each elastic connecting segment 27 has a locking hook 24 on its bottom outer side, which is used to position and engage with the key seat 28. The locking hook 24 has a hook-shaped structure with openings at both ends, and a hollow cavity 25 is formed inside. The hollow cavity 25 allows the locking hook 24 to undergo controllable elastic deformation during insertion or disassembly, thereby improving the flexible deformation capability of the locking hook 24.

[0031] A filler 26 is provided inside the hollow cavity 25. The filler 26 is preferably a honeycomb cotton material with good sound absorption and resilience. This material can make full use of the space provided by the hollow cavity 25 and play a role in absorbing impact sound during the deformation of the hook 24 and the key action, thereby effectively reducing the noise generated when the keycap 2 moves up and down.

[0032] In addition, the softness of the filler 26 itself can also buffer the local pressure on the locking hook 24 during the removal of the keycap 2, reduce the wear of the locking hook 24 caused by frequent removal, and improve the service life of the whole machine.

[0033] A buffer positioning mechanism is also provided at the contact position between the keycap 2 and the key base 28. This buffer positioning mechanism is used to further reduce the impact noise when the keycap 2 is pressed down and improve the stability of the key.

[0034] The mechanism specifically includes a tapered protrusion 23 disposed on the upper end of the key base 28, and a tapered buffer portion 21 disposed on the lower end face of the keycap 2. The inner side of the tapered buffer portion 21 is provided with a tapered positioning groove for engaging with the tapered protrusion 23.

[0035] The aforementioned tapered structure not only provides a flexible buffer area to reduce mechanical impact during the pressing process, but also achieves precise positioning after the button rebounds, improving the consistency and tactile feedback of the button.

[0036] To further enhance the cushioning effect and structural elasticity, both the conical protrusion 23 and the conical buffer part 21 are made of elastic rubber material. This material has good deformation recovery ability, can be used repeatedly without easily deforming, and can continuously provide stable cushioning performance during use.

[0037] In order to ensure the structural stability of the locking hook 24 and prevent the key shaft 22 from loosening in the key seat 28, a limiting step surface 29 is provided on the inner side of the key seat 28 corresponding to the position of each locking hook 24;

[0038] The limiting step surface 29 is used to limit the insertion force and disengagement depth of the locking hook 24, ensuring that the key shaft 22 forms a stable position after being inserted into the key seat 28.

[0039] Furthermore, in order to reduce the impact area between structures and optimize the noise reduction effect, the upper surface of the locking hook 24 is designed as an inclined contact surface, and the limiting step surface 29 and the inclined contact surface form a line contact structure. This contact method can significantly reduce the noise generated by the impact compared with the surface contact structure, while avoiding the deformation concentration problem caused by a large contact surface.

[0040] Based on the above-mentioned structure, this utility model can also be widely applied to various silent keyboard structures. A silent keyboard may include one or more of the above-mentioned silent keys, each key is independently equipped with the above-mentioned noise reduction structure, thereby improving the overall quietness of key input and user comfort.

[0041] This utility model introduces honeycomb cotton filling for sound absorption, a conical buffer positioning structure, and an elastic locking hook 24 in conjunction with a limiting step for snapping, achieving an effective balance between noise reduction, structural stability, and user feel, and is suitable for various types of silent input devices.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
