Description

A soft-touch keyboard that prevents rattling and popping. Technical Field

[0001] This utility model relates to the field of keyboard structure technology, specifically a soft-touch keyboard that prevents abnormal noise. Background Technology

[0002] A keyboard typically consists of a base, a base plate, a circuit board, and keys. When a key is pressed, it causes the base plate and circuit board to move downwards towards the base. Springs are usually used to reset the keys. Pressing a key causes the base plate to collide with the base, resulting in noise. Although the springs provide cushioning for the base plate and base, because the springs are made of metal, the impact between the springs and the base plate, as well as the impact between the springs and the base, will produce noise. There are usually multiple springs between the base plate and the base, and the noise produced by multiple springs is chaotic, affecting the user experience. Summary of the Invention

[0003] This utility model discloses a soft-touch keyboard that prevents abnormal noises, in order to solve the technical problems of noise and abnormal sounds.

[0004] To solve the above-mentioned technical problems, the present invention proposes the following optimized technical solution:

[0005] A soft-touch keyboard with noise prevention includes a base, a base plate, a circuit board, a rebound assembly, and multiple keys. The top of the base is provided with a receiving groove. The base plate, the circuit board, and the multiple keys are connected from bottom to top and housed in the receiving groove. The rebound assembly is located between the base and the base plate.

[0006] The bottom of the receiving groove of the base is provided with a guide post, and the rebound assembly includes an upper rubber pad, a spring and a lower rubber pad, which are sequentially fitted onto the guide post from bottom to top; the base plate presses on the upper rubber pad.

[0007] Furthermore, the bottom of the base is provided with an anti-slip structure.

[0008] Furthermore, the upper and lower adhesive pads are made of TPU material.

[0009] Furthermore, there are multiple guide posts, and the number of rebound components is the same as the number of guide posts, with each rebound component corresponding to a guide post.

[0010] Furthermore, both the upper rubber pad and the lower rubber pad include a base and a connecting part, the diameter of the base is larger than the diameter of the connecting part, and the spring is sleeved on the connecting part of the upper rubber pad and the connecting post of the lower rubber pad.

[0011] Furthermore, the base plate has holes through which the circuit board portion passes and is connected to the base plate.

[0012] Furthermore, the base is provided with a power hole, through which a power cord passes to connect to the circuit board.

[0013] Furthermore, it also includes a keypad, which is located between the circuit board and the plurality of buttons, with the lower end of each button passing through the keypad and connecting to the circuit board.

[0014] The present invention has the following advantages over the prior art:

[0015] The anti-noise soft-tumble keyboard provided by this utility model is equipped with a rebound component. The rebound component is equipped with a lower rubber pad, a spring, and an upper rubber pad. The spring is located between the lower rubber pad and the upper rubber pad. When the key is pressed, the base plate compresses the spring. The upper rubber pad is between the spring and the base plate, and the lower rubber pad is between the spring and the base. That is, the spring and the base, and the spring and the base plate play a role in complete sound insulation. The simple structure cleverly achieves the anti-noise and soft-tumble effect.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Referring to Figures 1-6, a soft-touch keyboard with anti-noise mechanism includes a base 1, a base plate 2, a circuit board 3, a rebound assembly 14, and multiple keys 4. The top of the base 1 is provided with a receiving groove 5. The base plate 2, the circuit board 3, and the multiple keys 4 are connected from bottom to top and housed in the receiving groove 5. The rebound assembly 14 is located between the base 1 and the base plate 2.

[0025] The bottom of the receiving groove 5 of the base 1 is provided with a guide post 6. The rebound assembly 14 includes an upper rubber pad 7, a spring 8 and a lower rubber pad 9. The lower rubber pad 9, the spring 8 and the upper rubber pad 7 are sequentially fitted onto the guide post 6 from bottom to top. The base plate 2 presses on the upper rubber pad 7.

[0026] When in use, press down button 4. Button 4 moves downward, causing circuit board 3 and base plate 2 to compress spring 8 downward. Both ends of spring 8 are covered by upper rubber pad 7 and lower rubber pad 9 respectively, which achieves complete silence and soft and elastic effect.

[0027] In this embodiment, the bottom of the base 1 is provided with an anti-slip structure 10, which plays an anti-slip role and prevents the base 1 from sliding on the table.

[0028] In this embodiment, the upper adhesive pad 7 and the lower adhesive pad 9 are made of TPU material, which is a soft material and can play a role in noise reduction.

[0029] In this embodiment, there are multiple guide posts 6, and the number of rebound components 14 is the same as the number of guide posts 6. Each rebound component 14 is fitted onto a guide post 6 in a one-to-one correspondence. The multiple guide posts 6 and rebound components 14 are designed to better function as a spring 8 on the base plate 2.

[0030] In this embodiment, both the upper rubber pad 7 and the lower rubber pad 9 include a base 11 and a connecting portion 12. The diameter of the base 11 is larger than the diameter of the connecting portion 12. The spring 8 is sleeved on the connecting portion 12 of the upper rubber pad 7 and the connecting post of the lower rubber pad 9. Specifically, the spring 8 is sleeved on the connecting portion 12 of the upper rubber pad 7 and the connecting post of the lower rubber pad 9, with both ends of the spring 8 abutting against the base 11 of the upper rubber pad 7 and the base 11 of the lower rubber pad 9, thereby achieving the effect of wrapping the spring 8 between the upper rubber pad 7 and the lower rubber pad 9.
