Description

Technical Field

[0001] The utility model relates to the technical field of computer keyboards, in particular to a shock-absorbing keyboard with bowl-shaped convex points on the bottom. Background Art

[0002] A computer keyboard is an input device used to input information such as text, symbols and commands into a computer system. It is usually composed of a series of keys, each of which represents a character or function. When using a computer now, a cushioning keyboard with a bowl-shaped protrusion on the bottom is usually used to provide a softer key touch and reduce hand fatigue caused by long-term use of the keyboard. The protrusion under the key can absorb part of the impact force generated by hitting the key, making the keyboard operation more comfortable.

[0003] A Chinese patent application numbered CN202221153499.6 discloses a cushioning keyboard with a bowl-shaped protrusion on the bottom. Since a soft rubber layer with a bowl-shaped protrusion is arranged under the PCB board, the vibration of the keyboard when the key shaft is pressed is alleviated, which has a mute effect and does not affect the original tapping feeling of the key shaft. The bowl-shaped protrusions are distributed between the key shafts, which not only achieves stable cushioning, but also maintains the stability of the entire keyboard. However, when the cushioning keyboard with a bowl-shaped protrusion on the bottom is used, the keycap, PCB board, key shaft, and hard rubber positioning layer are connected. The soft rubber layer with bowl-shaped bumps is connected with screws and then installed in the base plate and the shell to complete the assembly of the keyboard. The key shaft is stabilized and cushioned by the bowl-shaped bumps to maintain the stability of the entire keyboard. However, it is not convenient to quickly separate the keycaps from the base plate and the shell, and the screws need to be removed by tools, which makes the maintenance and repair of the keyboard cumbersome. The replacement or repair of the internal components of the keyboard is inefficient, time-consuming and labor-intensive, which makes it inconvenient to replace or repair the internal components of the keyboard, affecting the practicability of the cushioned keyboard.

Please refer to the comparative document (application number CN202221153499.6, named A shock-absorbing keyboard with bowl-shaped bump on the bottom) for details, which will not be repeated here.

[0030] As can be seen from the above, when in use, the shell 1 is placed where the keyboard needs to be used, the hard glue positioning layer 7 is connected through the PCB board 3 and the bowl-shaped convex soft glue layer 6, the hard glue positioning layer 7 is matched with the keycap 2, and then the accessories are placed in the shell 1, so that the keycap 2 is connected to the shell 1. At this time, the keycap 2 is plugged and fixed on the key shaft inside the shell 1, thereby completing the assembly of the keyboard. When the user presses the keycap 2, the key shaft can achieve shock absorption through the bowl-shaped convex soft glue layer 6, so that the convex point under the key can absorb part of the impact force generated by hitting the key, making the keyboard operation more comfortable.

[0031] refer to Figure 1-Figure 4As shown, a disassembly mechanism 4 is located between the keycap 2 and the shell 1, and the disassembly mechanism 4 is used to quickly separate the keycap 2 from the shell 1. The disassembly mechanism 4 includes fixing grooves opened on both sides of the top of the shell 1 and fixing blocks 41 fixed on both sides of the keycap 2. The two fixing blocks 41 correspond to the two fixing grooves, and a positioning mechanism for positioning the two fixing blocks 41 is arranged between the two fixing blocks 41 and the two fixing grooves. The positioning mechanism includes a movable rod 42 inserted on one side of the shell 1 and a positioning groove penetrating through one side of the fixing block 41. The movable rod 42 is plugged into the positioning groove, and a reset mechanism for resetting the movable rod 42 is arranged between the movable rod 42 and the shell 1. A control block 45 is fixed on one side of the movable rod 42. The reset mechanism includes a movable groove opened in the shell 1 and a baffle 43 fixed on the outer wall of the movable rod 42. A first spring 44 is connected between the baffle 43 and the movable groove, and the first spring 44 is sleeved on the outside of the movable rod 42.

[0032] Through the above technical solution:

[0033] When in use, first pull the control block 45 to drive the movable rod 42 to move, and the movement of the movable rod 42 drives the baffle 43 to move, so that the baffle 43 moves in the movable groove, and the movement of the baffle 43 drives the first spring 44 to contract. The contraction of the first spring 44 separates the movable rod 42 from the positioning groove. After the movable rod 42 is separated from the positioning groove, the keycap 2 and the shell 1 can be quickly separated without the need to remove the screws with tools, making it easier to maintain and repair the keyboard, thereby greatly improving the efficiency of replacing or repairing the internal components of the keyboard.

[0034] In addition, refer to Figure 1-Figure 3 , Figure 5 and Figure 6 As shown, a supporting mechanism 5 for supporting the shell 1 is provided on one side of the shell 1, and the supporting mechanism 5 includes a fixed plate 51 fixed on one side of the shell 1 and a rotating seat 52 rotatably installed inside the fixed plate 51, a supporting plate 53 is fixed to the bottom of the rotating seat 52, and an anti-slip seat is installed at the bottom of the supporting plate 53, and a limiting mechanism for limiting the rotating seat 52 is provided between the rotating seat 52 and the fixed plate 51, and the limiting mechanism includes a moving plate 54 installed on the top of the fixed plate 51 and an extrusion seat 56 fixed at the bottom of the moving plate 54, and a plurality of friction blocks are fixed on one side of the extrusion seat 56, and the plurality of friction blocks correspond to the rotating seat 52, and an extrusion mechanism for extruding the moving plate 54 is provided between the moving plate 54 and the fixed plate 51, and a linkage plate 55 is fixed on one side of the moving plate 54, and the extrusion mechanism includes a groove cavity opened on the top of the fixed plate 51 and a moving block 57 installed inside the groove cavity, a second spring 58 is connected between the moving block 57 and the groove cavity, and the moving block 57 is fixed to the moving plate 54.

[0035] Through the above technical solution:

[0036] When in use, the linkage plate 55 is pushed to drive the moving plate 54 to move, and the movement of the moving plate 54 drives the moving block 57 to move, and the movement of the moving block 57 drives the second spring 58 to contract, and the contraction of the second spring 58 makes the moving plate 54 drive the extrusion seat 56 to move, and the extrusion seat 56 is separated from the rotating seat 52 by the movement of the extrusion seat 56. After the mutual separation of the extrusion seat 56 and the rotating seat 52, the rotating seat 52 drives the supporting plate 53 to rotate, and the rotation of the supporting plate 53 drives the anti-slip seat to rotate synchronously, so that the shell 1 can be supported, and the support angle can be adjusted conveniently, so as to reduce the fatigue of the hands and wrists and the discomfort caused by using the keyboard for a long time.
