Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, specifically to a keyboard with vibration damping effect. Background Technology

[0002] A keyboard, as a peripheral electronic input device, is composed of different key technologies and electronic switch systems. Its main function is to input data, and it can also be used in a computer system to operate other machines or devices.

[0003] Gasket keyboards are a type of mechanical keyboard design inspired by gasket-mounted keyboards. Their key feature is the use of rubber pads between the keyboard's base and the keyboard plate to provide a floating and vibration-damping effect. These rubber pads are typically located around the perimeter of the keyboard and can be divided into several small areas. This design allows the keyboard to create an independent damping space around each key, providing a more balanced and stable typing experience. Additionally, the rubber pads can adjust the keyboard's sensitivity and rebound force.

[0004] Currently, Gasket keyboards on the market typically have elastic elements set on the outer edge of the circuit board module. For example, a soft and springy noise-absorbing keyboard and its manufacturing method are described in patent publication number CN118538559A. This keyboard achieves a soft and springy pressing effect by arranging multiple silicone soft springs on the outer edge of the circuit board module, and reduces the vibration frequency during the key pressing process by using the silicone soft springs, thereby reducing the keyboard's operating noise.

[0005] In practical use, the inventors found that the structure design of placing the elastic element directly on the outer edge of the circuit board module has limited rebound effect. Relying solely on the elasticity of silicone makes it difficult to achieve a greater rebound amplitude. Furthermore, the contact area between the elastic element and the outside of the circuit board module is limited, which can easily lead to the twisting and deformation of the elastic element, which is not conducive to the long-term use of the keyboard. Summary of the Invention

[0006] This invention provides a keyboard with vibration damping effect, which adopts an outwardly extending cantilever structure connected to an elastic element, thereby improving the stability of the connection. The outwardly extending cantilever structure also increases the rebound amplitude of the key press, solving the technical problem of limited key rebound effect.

[0007] The objective of this utility model is achieved through the following means:

[0008] A keyboard with vibration damping effect includes a housing, a circuit board, and keys disposed on the circuit board. A middle plate for fixing the keys is suspended inside the housing by a vibration damping assembly. The vibration damping assembly includes a plurality of elastic members surrounding the outer edge of the middle plate. The outer edge of the middle plate is provided with an outwardly extending cantilever structure, and the cantilever structure is connected to the elastic members.

[0009] Furthermore, the cantilever structure consists of cantilever bodies spaced at the outer edge of the middle plate and a connecting portion disposed at one end of the cantilever bodies.

[0010] Furthermore, two cantilever bodies are symmetrically arranged, and the two cantilever bodies are arranged parallel to each other at intervals on the outer edge of the middle plate.

[0011] Furthermore, the elastic element is composed of an elastic body for supporting the cantilever body and a positioning protrusion integrally formed on the upper end of the elastic body, and the positioning protrusion is engaged with the connecting part.

[0012] Furthermore, the middle plate is provided with outwardly extending positioning parts around its perimeter, and the outer shell is provided with limiting grooves for fitting and cooperating with the positioning parts, with a gap between the positioning parts and the limiting grooves.

[0013] Furthermore, a sound-absorbing layer is provided between the middle plate and the circuit board.

[0014] Furthermore, the outer shell is composed of a top cover and a base, with a light-transmitting frame between the base and the top cover, and the top cover and the base are fixedly connected by screws and / or buckles.

[0015] Furthermore, several buffer feet are installed on the bottom of the circuit board.

[0016] Furthermore, a vibration damping pad is provided at the bottom of the housing, and a plurality of support columns for supporting the circuit board are evenly arranged on the vibration damping pad.

[0017] Furthermore, the bottom of the vibration damping pad is integrally formed with a honeycomb structure.

[0018] This invention uses an outwardly extending cantilever structure connected to an elastic element, which not only improves the stability of the connection but also significantly enhances the rebound amplitude of the key press, providing users with a more comfortable and smooth typing experience.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] In this embodiment, refer to Figure 1 - Figure 7 The keyboard with vibration damping effect is specifically implemented as follows: it includes a shell 1, a circuit board 2 and keys 3 set on the circuit board 2. A middle plate 4 for fixing the keys 3 is suspended and installed in the shell 1 by a vibration damping component. The vibration damping component includes a number of elastic elements 5 arranged around the outer edge of the middle plate 4. The outer edge of the middle plate 4 is provided with an outwardly extending cantilever structure 4A, which is connected to the elastic elements 5.

[0029] Furthermore, the cantilever structure 4A comprises cantilever bodies 41A spaced apart on the outer edge of the middle plate 4 and a connecting portion 42A located at one end of the cantilever bodies 41A. Two cantilever bodies 41A are symmetrically arranged, with parallel spacing between them on the outer edge of the middle plate 4. The symmetrical arrangement of the two cantilever bodies 41A provides a more uniform force distribution on the middle plate 4, and the parallel spacing not only provides space for deformation of the cantilever bodies 41A but also reduces the space occupied by the cantilever bodies 41A, effectively reducing the peripheral area of ​​the keyboard.

[0030] Furthermore, the elastic element 5 consists of an elastic body 501 for supporting the cantilever body 41A and a positioning protrusion 502 integrally formed on the upper end of the elastic body 501. The positioning protrusion 502 engages with the connecting part 42A. This engagement design between the cantilever structure 4A and the elastic element 5 effectively prevents the elastic element 5 from twisting and deforming, extending the keyboard's lifespan. Moreover, using the elastic body 501 to support the cantilever body 41A increases the contact area between the cantilever structure 4A and the elastic element 5, significantly improving the stability of the key 3 when pressed.

[0031] Furthermore, the middle plate 4 is provided with outwardly extending positioning parts 4B on all four sides, and the outer shell 1 is provided with limiting grooves 101 for engaging with the positioning parts 4B, thereby preventing significant left and right displacement of the middle plate 4 and the circuit board 2 structure. In addition, the gap between the positioning parts 4B on all four sides of the middle plate 4 and the limiting grooves 101 in the outer shell 1 provides a certain amount of movement space for the keyboard, further enhancing the vibration damping effect.

[0032] Furthermore, a sound-absorbing layer 6 is provided between the middle plate 4 and the circuit board 2, which effectively reduces the noise generated when the button 3 is operated, creating a quieter user environment.

[0033] In this embodiment, the sound-absorbing layer 6 is made of commonly available sound-absorbing cotton material, and the elastic element 5 and the vibration damping pad 8 are made of silicone material.

[0034] Furthermore, the outer casing 1 is composed of a top cover 1A and a base 1C. A light-transmitting frame 1B is provided between the base 1C and the top cover 1A. The top cover 1A, the light-transmitting frame 1B, and the base 1C are fixedly connected by snap-fit ​​fasteners. The structure is sturdy and easy to disassemble and repair. The design of the light-transmitting frame 1B also enhances the overall aesthetics of the keyboard and improves the user experience.

[0035] Furthermore, several buffer feet 7 are fitted and installed at the bottom of the outer edge of the circuit board 2, and a vibration damping pad 8 is provided at the bottom of the outer casing 1. Several support pillars 801 for supporting the circuit board 2 are evenly arranged on the vibration damping pad 8. The buffer feet 7 at the bottom of the circuit board 2, together with the vibration damping pad 8 and support pillars 801 at the bottom of the outer casing 1, constitute a multi-layer vibration damping structure, making the keyboard more stable during use and reducing the impact of vibration on the surrounding environment.

[0036] Furthermore, the bottom of the vibration damping pad 8 is integrally formed with a honeycomb structure, which enhances the strength and stability of the vibration damping pad 8, allowing the keyboard to maintain stable performance even after long-term use.

[0037] This invention employs an outwardly extending cantilever structure 4A connected to an elastic element 5, which not only improves the stability of the connection but also significantly enhances the rebound amplitude of the key 3, providing users with a more comfortable and smooth typing experience. In summary, the keyboard with vibration damping provided by this invention has the advantages of structural stability, good rebound effect, vibration reduction and noise reduction, and long service life, providing users with a superior typing experience.
