Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, specifically a mechanical keyboard with easily detachable keycaps. Background Technology

[0002] Mechanical keyboards gradually gained popularity in the 1970s and 1980s. They were initially designed to meet the high demands of professional typists and computer operators for the feel and reliability of input devices. Each key on a mechanical keyboard consists of an independent mechanical switch, providing better tactile feedback and key lifespan.

[0003] Currently, in existing technologies, some mechanical keyboards are prone to keycap damage if the keycaps are not removed properly. For example, some keycaps are fixed to the switches by a clip structure. If the force is applied in the wrong direction or too much force when removing the keycaps, the clip may break, rendering the keycaps unusable. In view of this, we propose a mechanical keyboard that makes it easy to remove keycaps. Utility Model Content

[0004] The main objective of this invention is to provide a mechanical keyboard with easily detachable keycaps, which can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model proposes a mechanical keyboard with easily removable keycaps, comprising a keyboard body, an indicator light on the keyboard body, a key switch housing fixedly connected to the inner wall of the keyboard body, a keycap snapped onto the key switch housing, and an installation / removal device provided on the key switch housing, the installation / removal device comprising:

[0006] The key shaft housing has a clearance groove on its surface. A roller is rotatably connected in the clearance groove. Multiple sets of rollers are provided. A fixing strip is fixedly connected to the outer wall of a set of rollers near the clearance groove.

[0007] A spring assembly is provided on the outer wall of the key shaft housing. The spring assembly includes a fixed shaft, which is fixedly connected to the outer wall of the key shaft housing. The fixed shaft is elastically connected to the rotating cylinder through a spring.

[0008] An arc-shaped plate, wherein the rotating cylinder is fixedly connected to the arc-shaped plate, and multiple sets of the arc-shaped plate are provided, and an extrusion column is fixedly connected to one end of the arc-shaped plate near the fixed strip;

[0009] A sliding groove is provided on the surface of the key shaft housing, and a pressing strip is slidably connected to the sliding groove. The pressing strip is limited by an arc plate.

[0010] Preferably, the inner wall of the key switch housing is provided with an anti-misalignment component, which includes a trapezoidal block. The trapezoidal structure of the trapezoidal block can guide the keycap to accurately enter the center position of the key switch housing, preventing the keycap from shifting during insertion.

[0011] Preferably, a trapezoidal block is fixedly connected to the inner wall of the key switch housing. The trapezoidal block is arranged in a circumferential array of multiple sets. The trapezoidal block effectively prevents the keycap from shifting during the installation process between the keycap and the key switch housing, thus playing a role in positioning and preventing deviation.

[0012] Preferably, a fixing block is fixedly connected to the outer wall of the trapezoidal block, and the fixing block is fixedly connected to the elastic sheet.

[0013] Preferably, the elastic sheet is provided in multiple sets, and two sets of the elastic sheet are elastically connected by a return spring. The squeezing force will cause the elastic sheet to elastically deform. Once the keycap is fully inserted, the elastic sheet returns to its original position under the action of the return spring.

[0014] Preferably, the elastic sheet is fixedly connected to the round bump, so that when the keycap is inserted into the key switch housing, the round bump will contact the keycap first.

[0015] Preferably, multiple sets of the elastic sheet, the return spring, and the round protrusion are provided.

[0016] This invention provides a mechanical keyboard with easily removable keycaps. It offers the following advantages:

[0017] (1) The mechanical keyboard with easy-to-remove keycaps uses an installation and removal device. When the keycap is inserted downwards, it contacts the roller in the clearance groove. The rolling friction makes the keycap operation smoother. At the same time, the rotation of the last set of rollers drives the fixing strip to flip downwards. As the fixing strip flips downwards, the fixing strip presses down the squeezing column, which drives the arc plate to flip. The arc plate pushes the pressing strip to slide upwards in the sliding groove, which is located between the keycap and the key switch housing. This makes it easy for the user to press the raised part of the pressing strip with an external part, which drives the arc plate to flip and push the fixing strip to rotate upwards. The rotation of the roller causes the keycap to disengage from the locking limit of the key switch housing, realizing a convenient and safe disassembly operation.

[0018] (2) The mechanical keyboard with easy-to-remove keycaps uses an anti-misalignment component. When the keycap is inserted or removed, the trapezoidal structure of the trapezoidal block guides the keycap to the center of the key switch housing accurately, preventing the keycap from shifting during insertion. When the keycap is inserted into the key switch housing, the round bump will contact the keycap first. The elastic sheet on the round bump will deform elastically and return to its original position under the action of the return spring. When the keycap is pressed, the key switch housing will be subjected to external force. The trapezoidal block and round bump on the key switch housing can continuously position and fix the keycap, so that the round bump always maintains stable support for the keycap and reduces misoperation caused by keycap misalignment.

[0030] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0031] 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.

[0032] Please see Figures 1-5 This utility model proposes a mechanical keyboard with easily removable keycaps, including a keyboard body 1, an indicator light 2 on the keyboard body 1, a key switch housing 4 fixedly connected to the inner wall of the keyboard body 1, and keycaps 3 snapped onto the key switch housing 4. The indicator light 2 on the keyboard is mainly used to provide feedback to the user on the current working status of the keyboard. Common indicator lights 2 include Num Lock, Caps Lock, and Scroll Lock. The keycaps 3 are the parts on the keyboard body 1 used for striking, usually made of plastic. The key switch is mainly composed of key switch housing 4, a core, a spring, and contacts. When a key is pressed, the core is pressed down, activating the internal metal contacts, closing the circuit, and thus sending a key signal to the computer. The key switch housing 4 is provided with an installation and removal device 5, which includes a recessed groove 51.

[0033] Furthermore, a clearance groove 51 is formed on the surface of the key switch housing 4, and a roller 52 is rotatably connected in the clearance groove 51. Multiple sets of rollers 52 are provided. A fixing strip 53 is fixedly connected to the outer wall of the set of rollers 52 closest to the clearance groove 51. When the keycap 3 is inserted downwards, it contacts the roller 52 in the clearance groove 51. The rolling friction of the roller 52 has a much lower coefficient of friction than sliding friction. Sliding friction will occur between the keycap 3 and the key switch housing 4. This friction will gradually wear down the keycap 3 and the key switch housing 4, while the roller 52 has… This effectively reduces friction, making the operation of keycap 3 smoother. Simultaneously, the rotation of the last set of rollers 52 causes the fixed strip 53 to flip downwards. A spring assembly 54 is provided on the outer wall of the key switch housing 4. The spring assembly 54 includes a fixed shaft 541, which is fixedly connected to the outer wall of the key switch housing 4. The fixed shaft 541 is elastically connected to the rotating cylinder 543 via a spring 542. The rotating cylinder 543 rotates under force, causing the spring 542 to tighten, deforming it and generating a force that compresses the fixed shaft 541. During the compression process, the spring 542 converts the work done by the external force into elastic potential energy and stores it. When the external force disappears, the elastic potential energy stored in the spring 542 is released, pushing the fixed shaft 541 back to its initial position. The rotating cylinder 543 is fixedly connected to the arc plate 55. Multiple sets of arc plates 55 are provided. An extrusion column 56 is fixedly connected to one end of the arc plate 55 near the fixed strip 53. As the fixed strip 53 flips downward, the fixed strip 53 presses down on the extrusion column 56, causing the arc plate 55 to flip. The surface of the key shaft housing 4 has a sliding opening. The movable groove 57 and the sliding groove 57 are slidably connected to the pressing strip 58. The pressing strip 58 is limited by the arc plate 55. In the initial state, the pressing strip 58 is set inside the lower part of the keyboard body 1. The flipping of the arc plate 55 pushes the pressing strip 58 to slide upward in the sliding groove 57, which is located between the keycap 3 and the key switch housing 4. This makes it convenient for the user to press the raised part of the pressing strip 58 with an external part, which drives the arc plate 55 to flip and push the fixing strip 53 to rotate upward. The rotation of the roller 52 causes the keycap 3 to disengage from the locking limit of the key switch housing 4.

[0034] Example 2

[0035] Based on Example 1, please refer to Figures 6-8The inner wall of the key switch housing 4 is provided with an anti-misalignment component 6, which includes a trapezoidal block 61. The trapezoidal structure of the trapezoidal block 61 can guide the keycap 3 to accurately enter the center position of the key switch housing 4, preventing the keycap 3 from shifting during insertion. The trapezoidal block 61 is fixedly connected to the inner wall of the key switch housing 4. There are multiple sets of trapezoidal blocks 61 in a circumferential array. The trapezoidal blocks 61 effectively prevent the keycap 3 from shifting during the installation of the keycap 3 and the key switch housing 4, playing a positioning and anti-misalignment role. The outer wall of the trapezoidal block 61 is fixedly connected with a fixing block 62, which is fixedly connected to an elastic sheet 63. There are multiple sets of elastic sheets 63, and two sets of elastic sheets 63 are elastically connected by a return spring 64. The compressive force will cause the elastic sheet 63 to shift. 3. After elastic deformation, once the keycap 3 is fully inserted, the elastic sheet 63 returns to its original position under the action of the return spring 64. The elastic sheet 63 is fixedly connected to the round bump 65. When the keycap 3 is inserted into the key switch housing 4, the round bump 65 will contact the keycap 3 first. When the keycap 3 is pressed, the key switch housing 4 will be subjected to external force. Due to the presence of the anti-displacement component 6, the trapezoidal block 61 and the round bump 65 on the key switch housing 4 can continuously position and fix the keycap 3. Even when frequent key presses cause the keycap 3 to be subjected to forces in different directions, the synergistic effect of the elastic sheet 63 and the return spring 64 can ensure that the round bump 65 always maintains stable support for the keycap 3, reducing misoperation caused by the keycap 3 being displaced.

[0036] When the keycap 3 is inserted downwards, it contacts the roller 52 in the recess 51. The rolling friction of the roller 52 has a much lower coefficient of friction than sliding friction. Sliding friction occurs between the keycap 3 and the key switch housing 4, which gradually wears down the keycap 3 and the key switch housing 4. The roller 52 effectively reduces this friction, making the keycap 3 operate more smoothly. At the same time, the rotation of the last set of rollers 52 causes the fixing strip 53 to flip downwards. As the fixing strip 53 flips downwards, it presses down and squeezes... The column 56 drives the arc plate 55 to rotate, causing the rotating cylinder 543 on the arc plate 55 to rotate under force, which in turn causes the spring 542 to tighten, causing the spring 542 to deform and generate a force that compresses the fixed shaft 541. During the compression process, the spring 542 converts the work done by the external force into elastic potential energy and stores it. The rotation of the arc plate 55 pushes the pressing strip 58 to slide upward in the sliding groove 57, which is located between the keycap 3 and the key switch housing 4, making it convenient for the user to press the raised part of the pressing strip 58 with an external part, thereby driving the arc plate 56 to rotate. 5. Flipping the roller 52 causes the keycap 3 to disengage from the key switch housing 4, enabling convenient and safe disassembly. During keycap insertion and removal, the trapezoidal structure of the trapezoidal block 61 guides the keycap 3 accurately into the center of the key switch housing 4, preventing it from shifting during insertion. When the keycap 3 is inserted into the key switch housing 4, the round protrusion 65 contacts it first, and the elastic sheet 63 on the protrusion 65 elastically deforms. Once the keycap 3 is fully inserted... Under the action of the return spring 64, the elastic sheet 63 returns to its original position. When the keycap 3 is pressed, the key switch housing 4 is subjected to external force. Due to the presence of the anti-displacement component 6, the trapezoidal block 61 and the round protrusion 65 on the key switch housing 4 can continuously position and fix the keycap 3. Even when frequent key presses cause the keycap 3 to be subjected to forces in different directions, the synergistic effect of the elastic sheet 63 and the return spring 64 can ensure that the round protrusion 65 always maintains stable support for the keycap 3, reducing misoperation caused by the keycap 3 being displaced.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
