Description

Technical Field

[0001] This utility model relates to the field of sound-producing buttons, and in particular to mechanical sound-producing buttons and their keyboards. Background Technology

[0002] A computer keyboard is the channel through which control information for text is input into a computer, evolving from the keyboard of an English typewriter. Early keyboards were almost entirely mechanical, also known as mechanical contact keyboards. These keyboards used electrical contacts as markers and mechanical metal springs as the elastic mechanism. They had a firm feel, long key travel, and quick, crisp changes in key resistance, closely resembling the feel of a typewriter keyboard. Therefore, they were very popular at the time, and even today, a considerable number of people still fondly remember the feel of this type of keyboard.

[0003] However, traditional mechanical keyboards, such as the one protected by the patent application number CN201610014135.2 entitled "A Mechanical Keyboard", have poor stability, complex structure, and high cost. Utility Model Content

[0004] Therefore, it is necessary to provide a mechanical sound button to address the technical problems of poor stability, complex structure, and high cost of traditional mechanical keyboards.

[0005] A mechanical sound-emitting button includes: a keycap, a receiving plate, a spring-loaded silicone cap, a PCB board, a light-emitting receiving plate, and a support base; A sliding tube is provided in the middle area of ​​the inner wall of the sealing end of the keycap. The sliding tube has elastic openings on both sides of the end away from the keycap. An elastic plate is provided at each elastic opening of the sliding tube. Sliding protrusions are provided on the outer wall of the movable end of the elastic plate. A striking plate is provided on both sides of the opening end of the keycap. The middle area of ​​the receiving plate has a through opening, and the side of the receiving plate facing the keycap has a receiving slide tube that communicates with the through opening. Two sliding grooves are symmetrically formed on the inner wall of the receiving slide tube. An arc-shaped sliding plate is provided at one corner of the side of the receiving plate facing away from the receiving slide tube. The sliding tube is adapted to the receiving slide tube, inserted into the receiving slide tube and slidably connected to it. Sliding protrusions are adapted to the sliding grooves, with each sliding protrusion correspondingly inserted into a sliding groove and slidably connected to the receiving slide tube. The spring-loaded silicone cap is disposed on the PCB board, and a contact rod is provided on the inner wall of the sealing end of the spring-loaded silicone cap. The contact rod is used to contact the touch module on the PCB board. The spring-loaded silicone cap passes through the through-hole and is housed in the receiving slide tube. The PCB board is disposed on the light-emitting receiving plate, and a light-emitting strip is provided on the light-emitting receiving plate. The slide tube abuts against the sealing end of the spring-loaded silicone cap. The two striking plates can impact the receiving middle plate. The support base includes a support base plate, a support vertical plate, and an arc-shaped receiving slide plate; the support vertical plate is perpendicularly connected to the middle area of ​​the support base plate; the support vertical plate abuts against the side of the light-emitting receiving plate facing away from the PCB board; the arc-shaped receiving slide plate is connected to a corner of the side of the support base plate facing the support vertical plate; the arc-shaped receiving slide plate is adapted to the arc-shaped slide plate, and the arc-shaped slide plate is inserted into the arc-shaped receiving slide plate.

[0006] In one embodiment, the outer wall of the sealing end of the keycap is provided with a pressing groove.

[0007] In one embodiment, a retaining ring is provided on the side of the receiving plate facing away from the keycap, and the retaining ring abuts against the PCB board.

[0008] In one embodiment, the sliding tube is integrally formed with the keycap.

[0009] In one embodiment, the elastic plate is integrally formed with the keycap.

[0010] In one embodiment, the sliding protrusion is integrally formed with the elastic plate.

[0011] In one embodiment, the receiving slide tube and the receiving middle plate are integrally formed.

[0012] In one embodiment, the arc-shaped sliding plate and the receiving middle plate are integrally formed.

[0013] In one embodiment, the contact rod is integrally formed with the spring-loaded silicone cap.

[0014] A keyboard including the mechanical sound-producing buttons described in any of the above embodiments.

[0015] During operation, striking the aforementioned mechanical sound button causes the keycap to move a sliding tube into the receiving slide tube and downwards along it. During this process, each sliding protrusion corresponds to a sliding groove and moves downwards along it. Ultimately, the sliding tube compresses the spring-loaded silicone cap, causing the two striking plates to strike the receiving plate, producing a crisp sound. When the spring-loaded silicone cap is compressed, the contact rod on it abuts against the touch module on the PCB board. After striking, the spring-loaded silicone cap returns to its elastic deformation, driving the keycap away from the receiving plate via the sliding tube. During this process, each sliding protrusion corresponds to a sliding groove and moves upwards along it. This mechanical sound button exhibits high structural stability, a simple and ingenious design, low cost, and produces a crisp striking sound. Attached Figure Description
