Technical Field
[0001] This utility model relates to the technical field of a computer keyboard safety anti-collision and noise reduction device, and more specifically, to a computer keyboard safety anti-collision and noise reduction device. Background Technology
[0002] A computer keyboard is a set of arranged number keys, letter keys, or function keys used to input information into a terminal and send it into a predetermined system. It is one of the most important input devices of a computer system. A switchless mechanical keyboard is a special type of mechanical keyboard. Its characteristic is that it does not have a traditional physical switch structure. This type of keyboard usually adopts a switchless and keycapless design, which makes it more noise-reducing and quiet to use, and can avoid fatigue caused by prolonged use.
[0003] However, most keyboards currently on the market make a considerable amount of noise when the keycaps are struck, which can attract attention, especially in quiet places like libraries or conference rooms. Moreover, keyboards are relatively lightweight, making them easy to drop and damage if not handled carefully.
[0004] A search revealed that Chinese patent CN114546126A discloses a computer keyboard safety anti-collision and noise reduction device, which can achieve noise reduction when the keycaps are pressed.
[0005] However, this structure is not effective in protecting the keyboard casing from impacts in actual use. It can only protect the bottom of the keyboard casing. When the four corners of the keyboard casing fall to the ground, it is difficult to protect the four corners of the keyboard. Therefore, this utility model proposes a computer keyboard safety anti-collision and noise reduction device. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a computer keyboard safety anti-collision and noise reduction device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a computer keyboard safety anti-collision and noise reduction device, including a keyboard shell, the surface of which is provided with multiple grooves, each groove having a noise reduction structure inside, and a protective structure installed on the outside of the keyboard shell.
[0008] To ensure effective impact protection by installing four anti-collision corners at the four corners of keyboard shells of different sizes, the protective structure preferably includes multiple anti-collision corners, each installed at one of the four corners of the keyboard shell. All anti-collision corners are made of rubber. A sleeve is provided between every two anti-collision corners. Inside each sleeve are two extension rods, one end of which is fixedly connected to the surface of the corresponding anti-collision corner. Both extension rods are slidably connected inside the sleeve. A support block is installed at the center of the sleeve's inner cavity. A movable block is fixedly installed inside the sleeve at one end of each extension rod. A tension spring is provided between the support block and the movable block. The support block is fixedly installed at the center of the sleeve's inner cavity, and the movable block is slidably connected inside the sleeve. Both ends of the tension spring are fixedly connected to the support block and the movable block.
[0009] To reduce the noise generated by keycap striking and achieve a noise reduction effect, preferably, the noise reduction structure includes a mounting block slidably installed inside a groove. The mounting block has grooves on both sides of its outer wall, and the inner walls of the grooves are filled with sound-absorbing cotton. A keycap is mounted on the top of the mounting block, and the lower surfaces of both ends of the keycap are slidably connected to the outer surfaces of the sound-absorbing cotton inside the grooves. A sound-insulating pad is fixedly mounted on the upper surface of the mounting block, and the bottom of the keycap is fixedly connected to the upper surface of the mounting block via the sound-insulating pad. A first fixing block is fixedly installed at the bottom of the inner cavity of the groove, and the inside of the groove is filled with a waterproof rubber pad. A rubber tube is mounted on the top of the first fixing block, and a second fixing block is fixedly mounted at the bottom of the inner cavity of the keycap. The top end of the rubber tube passes through the mounting block and the keycap sequentially and is fixedly connected to the second fixing block.
[0010] The technical effects and advantages of this utility model are as follows:
[0011] 1. By setting up a protective structure, the distance between each pair of anti-collision corners can be adjusted according to the size of the keyboard by stretching the two extension rods respectively, which is convenient for protecting keyboard shells of different sizes. After the four adjusted anti-collision corners are installed at the four corners of the keyboard shell, they can be tightly installed at the four corners of the keyboard shell by the tension of the spring. The anti-collision corners can protect the four corners of the keyboard shell.
[0012] When a keyboard is dropped or impacted, the corner protectors will first come into contact with the impacted surface. The rubber corner protectors can mitigate the impact force, preventing the impact force from acting directly on the keyboard casing. Therefore, no matter from which angle the keyboard is dropped or impacted, the corner protectors can provide good impact protection and extend the keyboard's lifespan.
[0013] 2. By setting up a noise reduction structure, the force of pressing the keycap causes the keycap to squeeze the sound-absorbing pad. The sound-absorbing pad absorbs the friction noise between the keycap and the sound-absorbing pad. The squeezing of the sound-absorbing pad causes the keycap to slide on the groove opened on the mounting block. The sound-absorbing cotton in the groove absorbs the friction noise between the keycap and the groove, thereby reducing the noise generated by keycap striking and achieving the noise reduction effect.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] As attached Figure 1-4 The computer keyboard safety anti-collision and noise reduction device shown includes a keyboard housing 1, a plurality of grooves 2 are formed on the surface of the keyboard housing 1, and a noise reduction structure is provided inside the plurality of grooves 2. A protective structure is installed on the outside of the keyboard housing 1.
[0021] In a specific embodiment, as shown in the appendix Figure 1 , 2As shown in Figure 3, the protective structure includes multiple anti-collision corners 3, which are respectively installed at the four corners of the keyboard housing 1. All anti-collision corners 3 are made of rubber. A sleeve 4 is provided between every two anti-collision corners 3. Two extension rods 5 are provided inside the sleeve 4. One end of each extension rod 5 is fixedly connected to the surface of the corresponding anti-collision corner 3, and both extension rods 5 are slidably connected inside the sleeve 4. A support block 6 is installed in the center of the inner cavity of the sleeve 4. A movable block 7 is fixedly installed inside the sleeve 4 at one end of the extension rod 5. A tension spring 8 is provided between the support block 6 and the movable block 7. The support block 6 is fixedly installed in the center of the inner cavity of the sleeve 4, and the movable block 7 is slidably connected inside the sleeve 4. Both ends of the tension spring 8 are fixedly connected to the support block 6 and the movable block 7.
[0022] Specifically, the structure can be installed on the outside of the keyboard housing 1 to provide good anti-collision effect for the keyboard. Specifically, depending on the specific size of the keyboard, the two extension rods 5 extend and slide to both sides respectively, so that the movable block 7 slides inside the sleeve 4 to adjust the distance between each pair of anti-collision corners 3, which is convenient for protecting keyboard housings 1 of different sizes.
[0023] The four adjusted anti-collision corners 3 are respectively installed at the four corners of the keyboard housing 1. Since the support block 6 is fixedly installed in the center of the inner cavity of the sleeve 4, the movable block 7 will cause the tension spring 8 to be stretched and reset after sliding inside the sleeve 4. Then, after the tension spring 8 is reset, it provides the opposite tension, which can tightly install the four anti-collision corners 3 at the four corners of the keyboard housing 1. The anti-collision corners 3 are made of rubber material, which can protect the four corners of the keyboard housing 1.
[0024] Therefore, if the keyboard is dropped or impacted, the anti-collision corner 3 will first come into contact with the impacted surface. The rubber anti-collision corner 3 can mitigate the impact force, so that the impact force or shock force will not directly act on the keyboard shell 1, thus providing a good anti-collision effect for the keyboard and improving the service life of the keyboard.
[0025] In a specific embodiment, as shown in the appendix Figure 1 , 4As shown, the noise reduction structure includes a mounting block 9 that is slidably installed inside the groove 2. Slide grooves 10 are provided on both sides of the outer wall of the mounting block 9. The inner wall of the slide grooves 10 is filled with sound-absorbing cotton 11. A keycap 12 is provided on the top of the mounting block 9. The lower surfaces of both ends of the keycap 12 are slidably connected to the outer surfaces of the sound-absorbing cotton 11 inside the slide grooves 10. A sound-insulating pad 13 is fixedly provided on the upper surface of the mounting block 9. The bottom of the keycap 12 is fixedly connected to the upper surface of the mounting block 9 through the sound-insulating pad 13. A first fixing block 14 is fixedly installed at the bottom of the inner cavity of the groove 2. The inside of the groove 2 is filled with a waterproof rubber pad 15. A rubber tube 16 is provided on the top of the first fixing block 14. A second fixing block 17 is fixedly provided at the bottom of the inner cavity of the keycap 12. The top end of the rubber tube 16 passes through the mounting block 9 and the keycap 12 sequentially and is fixedly connected to the second fixing block 17.
[0026] Specifically, in this structure, the pressing of the keycap 12 can achieve a good noise reduction effect. Specifically, when the keycap 12 is pressed, the pressing force causes the keycap 12 to squeeze the sound-absorbing pad 13, and the sound-absorbing pad 13 absorbs the friction sound between the keycap 12 and the sound-absorbing pad 13 at the same time.
[0027] The pressure of the sound-absorbing pad 13 will cause the keycap 12 to slide on the groove 10 opened on the mounting block 9. The sound-absorbing cotton 11 in the groove 10 will absorb the friction sound between the keycap 12 and the groove 10.
[0028] At the same time, the rubber tube 16, which is fixedly connected to the second fixing block 17 inside the keycap 12, is also squeezed. The rubber tube 16 deforms and applies elastic force to the first fixing block 14, which is fixedly connected to the rubber tube 16, inside the groove 2. When the pressure on the keycap 12 disappears, the elastic force of the rubber tube 16 resets the keycap 12, achieving the effect of pressing and resetting the keycap 12. The waterproof rubber pad 15 is used to prevent water from entering the interior of the keyboard shell 1, thereby reducing the noise generated by the keycap 12 being struck, achieving the effect of noise reduction.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
