[0025] The keyboard of the application embodiment can be applied in cash register equipment and other electronic product fields, such as computer keyboard, calculator, etc.

[0026] Referring to Figures 1 to 2 The keyboard comprises a silica gel pad 1 and a plurality of keycaps 2. The silica gel pad 1 is used in cooperation with the plurality of keycaps 2, and when the keycaps 2 are pressed, the silica gel pad 1 is pressed downward. The silica gel pad 1 can play a role of triggering the switch of the keyboard; the silica gel pad 1 can also reduce the cavity sound and collision sound generated when the keyboard is struck, so that the typing is more quiet, thereby playing a role of reducing noise; the silica gel pad 1 can also improve the hand feeling of the keyboard; and the silica gel pad 1 can also play a certain buffering role to protect the circuit board and other components inside the keyboard from being damaged.

[0027] In some embodiments, the keyboard comprises a circuit board (not shown) located below the silica gel pad 1, and the circuit board is provided with a switch (not shown). When the keycaps 2 are pressed downward, part of the silica gel pad 1 moves downward to trigger the switch; when the keycaps 2 are released, the silica gel pad 1 rebounds, and the switch is not triggered.

[0028] In some embodiments, the top surface of part of the plurality of keycaps 2 is substantially square, the top surface of part of the plurality of keycaps 2 is substantially small rectangular, and the top surface of at least one of the plurality of keycaps 2 is substantially large rectangular.

[0029] In some embodiments, the length of the small rectangular is the same as the width of the square, and the width of the small rectangular is smaller than the width of the square. The length of the large rectangular is greater than the width of two squares, and the width of the large rectangular is the same as the width of the square.

[0030] In other embodiments, the length of the large rectangular can also be greater than the width of one square, and can also be greater than the width of a plurality of squares, which is not limited in the application.

[0031] In other embodiments, the length of the small rectangular can also be greater than the width of the square, which is not limited in the application.

[0032] The keycap 2 with a top surface in a substantially large oblong shape is relatively long, and can be a confirmation key, a return key, a space bar, etc.

[0033] In some embodiments, the keycap 2 is made of plastic, and the silica gel pad 1 is made of silica gel.

[0034] Referring to FIG. 1, a keyboard 1 is shown. The keyboard 1 includes a plurality of keycaps 2 and a silica gel pad 1. Figures 2 to 3 In some embodiments, the silica gel pad 1 includes a main body 11, a plurality of inclined walls 12, and a plurality of protruding parts 13. The plurality of inclined walls 12 are respectively connected with the main body 11. The plurality of protruding parts 13 are respectively connected with the plurality of inclined walls 12 and respectively located in spaces surrounded by the plurality of keycaps 2. When the keycap 2 is pressed, it presses the protruding part 13 downward, and the protruding part 13 supports the keycap 2 to improve the pressing feeling and prevent the key from being stuck.

[0035] In some embodiments, a part of the plurality of protruding parts 13 is in a cylindrical shape, and a part is in an elliptical cylindrical shape. At least one protruding part 13 includes a first end 131 and a second end 132 arranged oppositely along the length direction of the keycap 2, and a connecting part 133 connecting the first end 131 and the second end 132. The connecting part 133 is in a waist shape.

[0036] The protruding part 13 in the cylindrical shape is located in the space surrounded by the keycap 2 with a top surface in a substantially square shape. The protruding part 13 in the elliptical cylindrical shape is located in the space surrounded by the keycap 2 with a top surface in a substantially small oblong shape. The protruding part 13 with the waist-shaped connecting part 133 is located in the space surrounded by the keycap 2 with a top surface in a substantially large oblong shape.

[0037] The protruding part 13 with the waist-shaped connecting part 133 has the following advantages. First, the first end 131 and the second end 132 provide two contact points, and when the two ends of the keycap 2 are pressed, the keys of the keyboard can be triggered, and a good feeling can be ensured. Second, the connecting part 133 in the middle connects the first end 131 and the second end 132 into one, and the problem of layered feeling is avoided. Third, the connecting part 133 in the middle is thin, which can reduce the influence of the connecting part 133 in the middle on the feeling. The silica gel pad 1 not only ensures the feeling experience of the user, but also reduces the cost compared with the complex structure of using a balance bar.

[0038] In some embodiments, the plurality of protruding parts 13 are arranged in an array on the main body 11. The plurality of protruding parts 13 can be aligned or staggered.

[0039] In some embodiments, the edge of the first end 131 is in a circular arc shape.

[0040] In some embodiments, the edge of the second end 132 is in a circular arc shape.

[0041] In some embodiments, the protruding part 13 is in a solid structure, which can provide better support force and prevent deformation when pressed, so as to avoid affecting the feeling and even causing the key to be stuck.

[0042] The feel of the keyboard depends on the inclined wall 12. In some embodiments, the cavity enclosed by the inclined wall 12 gradually narrows in the direction from the main body 11 to the protrusion 13, so as to provide a better feel.

[0043] In some embodiments, the thickness of the inclined wall 12 is smaller than the thickness of the main body 11, and the thickness of the main body 11 is smaller than the thickness of the protrusion 13.

[0044] In some embodiments, the central axis of the protrusion 13 is collinear with the central axis of the keycap 2, i.e. the protrusion 13 is located at the center of the keycap 2, so as to provide a better support effect.

[0045] Referring to FIG. 1, the silicone pad 1 includes a main body 11, a protrusion 13, and an inclined wall 12. Figures 4 to 7 In some embodiments, the main body 11 includes a top surface 111 and a bottom surface 112 arranged opposite to the top surface 111. The inclined wall 12 is arranged protruding from the top surface 111. The main body 11 is provided with a plurality of openings 113 penetrating the top surface 111 and the bottom surface 112. The inclined wall 12 encloses a plurality of cavities 121. The plurality of openings 113 respectively communicate with the plurality of cavities 121.

[0046] In some embodiments, the shape of the opening 113 is the same as the shape of the cross section of the protrusion 13.

[0047] In some embodiments, the area of the opening 113 is the same as the area enclosed by the bottom end of the inclined wall 12. The bottom end of the inclined wall 12 is connected with the main body 11, the top end of the inclined wall 12 is connected with the protrusion 13, and the area enclosed by the top end of the inclined wall 12 is smaller than the area enclosed by the bottom end of the inclined wall 12.

[0048] In some embodiments, the silicone pad 1 includes a protruding column 14 extending from the bottom of the protrusion 13 into the cavity 121 enclosed by the inclined wall 12. When the keycap 2 is pressed, the protruding column 14 triggers the switch on the circuit board.

[0049] In some embodiments, one protruding column 134 is arranged below the first end 131 and below the second end 132 respectively.

[0050] In some embodiments, the height of the protruding column 14 is lower than the depth of the cavity 121, so as to provide a moving space for the keycap 2, so as to provide an operation feel.

[0051] In some embodiments, the main body 11 is provided with a plurality of recesses 114 recessed from the bottom surface 112, and the plurality of recesses 114 respectively communicate with two adjacent openings 113, so as to vent air and prevent the silicone pad 1 from being unable to rebound due to suction.

[0052] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structure described in the above embodiments and shown in the accompanying drawings; any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
