Description

Technical Field

[0001] The utility model relates to the technical field of buttons, in particular to a novel noise reduction button. Background Art

[0002] As an indispensable data input tool in many electronic devices and automated machines, key keyboards play a vital role in inputting key information such as data and text. The quality of key switches is undoubtedly an important indicator to measure the quality of an input device experience. It not only requires a comfortable feel, but also a long service life. In the operating mechanism of the keyboard keys, the user gently presses the keycap to make the key shaft move down smoothly after being pressed, and then quickly returns to its position and moves up with the elastic force. This series of fine movements ensures the instant establishment or disconnection of the electrical connection, thereby completing the data input efficiently and accurately. This precise and efficient operation mode makes key keyboards an indispensable partner in our daily lives.

[0003] The key switches of common mechanical keyboards on the market will collide with the upper cover of the shell when the key rebounds upward, making noise. In order to solve the noise problem, existing key switches usually use noise reduction materials such as elastic sponge or silicone to fill between the shaft core and the shell, but this method often has problems such as poor noise reduction effect, easy aging of materials, and short life. As a result, the noise reduction effect of the key switch gradually weakens during later use, and the noise problem becomes more serious, affecting the user experience. Therefore, the utility model proposes a key switch with a new buffer structure to achieve noise reduction function. Summary of the invention

[0004] The utility model provides a novel noise reduction key, which solves the problem of noise generated when the shaft core rebounds by adopting a novel buffer structure.

[0007] Furthermore, one end of the sound reducing bone is tilted upward.

[0008] Furthermore, the sound reducing bone is provided with a contact portion protruding upward.

[0009] Furthermore, the shell is provided with a contact structure for cooperating with the sound reducing bone.

[0010] Furthermore, the sound-reducing bones are integrally formed on both sides of the shaft core.

[0011] Furthermore, the shell is provided with a track, and guide blocks cooperating with the track are provided on both sides of the shaft core.

[0012] Furthermore, the guide block and the sound reducing bone are integrally formed.

[0013] Furthermore, the shell includes a combinable upper cover and a lower cover, and the upper cover and the lower cover are respectively provided with mutually matching buckles and slots.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Embodiment 1:

[0029] In this embodiment, refer to Figure 1-Figure 8 , a new type of noise reduction key is specifically implemented, including a shell 1 and a shaft core 2, the shaft core 2 is slidably installed in the shell 1 through a spring 3, sound-reducing bones 4 are provided on both sides of the shaft core 2, and a clearance 2A is provided between the sound-reducing bones 4 and the shaft core 2. When the shaft core 2 rebounds upward, the sound-reducing bones 4 can first contact the shell 1 to form a buffering effect, effectively reducing the noise generated by the collision between the shaft core 2 and the shell 1. This design not only improves the noise reduction performance of the key switch, but also ensures that the shaft core 2 is more stable when rebounding, significantly improving the user experience. The clearance 2A makes the sound-reducing bones 4 have a certain elasticity, which can be deformed when contacting the shell, thereby providing a buffering effect.

[0030] like Figure 8 As shown, a gap is left between one side of the sound-absorbing bone 4 and the shaft core 2, so that the sound-absorbing bone 4 can extend independently from the shaft core 2, and the sound-absorbing bone 4 can be slightly deformed when subjected to external force, thereby improving the buffering effect. One end of the sound-absorbing bone 4 is tilted and tilted upward. The upward tilting design enables the sound-absorbing bone 4 to first come into contact with the housing 1 when the shaft core 2 rebounds, and to produce a greater deformation, thereby absorbing more impact energy, further improving the buffering and noise reduction effects.

[0031] Furthermore, the sound reducing bone 4 is provided with a contact portion 4A protruding upward. The protruding contact portion 4A increases the contact area between the sound reducing bone 4 and the housing 1, thereby improving the uniformity and stability of noise reduction. In addition, the shape and size of the contact portion 4A can be adjusted according to actual needs to adapt to the design of different housings 1, so that the key switch has better versatility and adaptability.

[0032] Furthermore, the sound-absorbing bones 4 are integrally formed on both sides of the shaft core 2. The integrally formed design makes the sound-absorbing bones 4 more stable and more firmly connected to the shaft core 2, thereby ensuring the effectiveness of the sound-absorbing bones 4 in reducing the rebound noise of the key switch. The manufacturing process is simplified, the stability of the structure is improved, and the reliability of the key switch is further ensured.

[0033] Furthermore, a track 9 is provided in the housing 1, and guide blocks 10 are provided on both sides of the shaft core 2 to cooperate with the track 9. Through the cooperation between the track 9 and the guide blocks 10, the shaft core 2 slides more stably and smoothly in the housing 1, reducing the shaking and jitter of the shaft core 2 during the sliding process, and further improving the stability and service life of the key switch.

[0034] Furthermore, the guide block 10 is integrally formed with the sound reducing bone 4. The integrally formed design of the guide block 10 and the sound reducing bone 4 not only ensures the stable sliding of the shaft core 2 in the housing 1, but also enhances the effect of the sound reducing bone 4 in reducing noise. When the shaft core 2 rebounds, the guide block 10 moves smoothly along the track 9, driving the contact portion 4A of the sound reducing bone 4 to contact the housing 1 to form a buffering effect, thereby reducing the noise generated by the collision between the shaft core 2 and the housing 1.

[0035] Furthermore, the housing 1 includes a combinable upper cover 1A and a lower cover 1B. The combinable upper cover 1A and the lower cover 1B cooperate with each other, making the assembly and maintenance of the key switch more convenient. The upper cover 1A and the lower cover 1B are respectively provided with a buckle 5 and a slot 6 that cooperate with each other. The buckle 5 and the slot 6 are engaged with each other, so that the upper cover 1A and the lower cover 1B are firmly connected, and the overall stability of the key switch is ensured.

[0036] Furthermore, the lower cover 1B is provided with a guide structure 7 for cooperating with the buckle 5, and the upper cover 1A is provided with a through slot 8 corresponding to the guide structure 7. The guide structure 7 enables the buckle 5 to slide more smoothly when cooperating with the slot 6, thereby reducing damage caused by improper assembly. At the same time, the design of the through slot 8 enables that when the shaft core 2 needs to be replaced, a card or other item is inserted through the through slot 8, and the guide structure 7 guides it to the middle of the buckle 5 and the slot 6, and the two are quickly separated, so that the upper cover 1A and the lower cover 1B can be separated without removing the entire housing 1, and the shaft core 2 can be quickly replaced.

[0037] Furthermore, a magnet 11 is embedded and installed at the lower end of the shaft core 2, and a through hole 12 corresponding to the magnet 11 is provided below the housing 1. The magnet 11 is used to connect with the outside to form a Hall switch, and the design of the through hole 12 makes the magnetic field interaction between the magnet 11 and the external device smoother, thereby ensuring the accuracy and stability of the Hall switch.

[0038] Furthermore, a fixing member 13 for connecting with the outside is provided at the lower end of the housing 1. The key switch can be quickly installed to a preset position by the fixing member 13, and the fixing effect is achieved by the interference fit between the fixing member 13 and the outside.

[0039] Furthermore, a light guide column 14 is provided on one side of the housing 1. The light guide column 14 allows the light at the lower end of the housing 1 to quickly pass through the key switch housing 1 and emit light to the key cap, thereby making the key cap glow, which increases the aesthetics while allowing the user to clearly see the position of the key in scenes such as dim lighting, thereby improving the user's convenience and operating experience.

[0040] Furthermore, the upper end of the shaft core 2 is provided with a cross key block 15 protruding from the shell 1, and the cross key block 15 can be matched with an external keycap, etc., and the cross key block 15 is composed of mutually perpendicular bones. In order to avoid errors in the installation direction of the keycap, edges with increased thickness are provided on both sides of the bone, and a slot 6 for matching with the keycap is provided at one end of the bone to improve the stability of the keycap installation.

[0041] The utility model provides a key switch with significant noise reduction effect. By arranging noise reduction bones 4 on both sides of the shaft core 2, when the shaft core 2 rebounds upward, the noise reduction bones 4 can first contact with the housing 1 to form a buffering effect, effectively reducing the noise generated by the collision between the shaft core 2 and the housing 1. This design not only improves the noise reduction performance of the key switch, but also ensures that the shaft core 2 is more stable when rebounding, significantly improving the user experience.

[0042] Embodiment 2:

[0043] like Fig. 9 As shown, the difference between this embodiment and the first embodiment is that the housing 1 is provided with a contact structure 1C that cooperates with the sound-reducing bone 4. The contact structure 1C protrudes from the housing 1 and contacts with the sound-reducing bone 4 when the shaft core 2 rebounds upward, so that the sound-reducing bone 4 forms a buffering effect, thereby reducing the noise generated by the collision between the shaft core 2 and the housing 1.
