Specific embodiments

[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] A Bluetooth leather case keyboard integrating anti - accidental touch touch buttons and a touchpad, referring to Figures 1-5 , includes a keyboard main body 1 provided on a leather case (not shown in the figure). The keyboard main body 1 includes an upper shell 13 and a bottom shell 16. The inner surface of the upper shell 13 is attached with a PCBA main board 15. Above the PCBA main board 15, a touchpad 131 and a plurality of honeycomb - shaped touch buttons 136 are provided on the upper shell 13. The upper surface of the PCBA main board 15 is integrated with touch chips corresponding to the touch buttons 136 and the touchpad 131. When a finger touches a certain button, the touch chip reports the coordinate information to the MCU (integrated on the PCBA main board 15). After the MCU reads the coordinates, it will determine which button is pressed, and then synchronously send the code of the corresponding button to the system to achieve the button function. The above - designed touchpad 131 can share a PCBA main board 15 with the key core part, so that the functions of the key core part, the PCBA main board 15 and the touchpad 131 can be integrated on one board to complete. In this way, the assembly process can be simplified to avoid errors and costs can be saved.

[0025] Among them, the touch chip (IC) is an existing technology that has been realized, and will not be elaborated here specifically.

The protruding plastic optical fiber 12 can define a single button area to prevent the user from accidentally touching other buttons.

[0028] Further, the light-emitting component is integrated on the PCBA main board 15. A hole 132 is provided on the groove 133 directly above the light-emitting component. A light guide portion 121 is provided at the tail end of the plastic optical fiber 12. The tail end of the light guide portion 121 extends into the hole 132 and is disposed on the light-emitting front surface of the light-emitting component. A light-emitting component (not shown in the figure) is installed on the PCBA main board 15. The tail end of the plastic optical fiber 12 is placed on the light-emitting front surface of the light-emitting component, and the backlight of the corresponding color will appear on the entire keyboard, replacing the traditional way of emitting light under the keys, which can ensure the brightness of the emitted light. At the same time, the plastic optical fiber 12 is of an integrated design, which can reduce the overall assembly process and production cost while ensuring uniform light emission.

[0029] Among them, the light-emitting component is preferably a high-brightness RGB LED lamp, but no limitation is made here.

[0030] Further, a protrusion 135 protruding upward is provided at the center of each touch key 136. The provided protrusion 135 can provide tactile feedback to the user to ensure that the current key has been pressed.

[0031] Among them, the protrusion 135 is preferably circular, but no limitation is made on the specific shape here.

[0032] Further, an upwardly protruding annular convex surface is further provided on the periphery of the touchpad 131. The annular convex surface can be used to define and inform the user of the touch area of the touchpad.

[0033] Further, the keyboard body 1 further includes a plurality of hemispherical fixing brackets 11. The hemispherical fixing brackets 11 are correspondingly disposed on the plastic optical fiber 12. A plurality of buckle portions are circumferentially provided at the bottom end of the hemispherical fixing brackets 11. A card slot 134 for the buckle portions to be inserted into is correspondingly provided on the periphery of the groove 133. During assembly, first place the plastic optical fiber 12 in the groove 133, and then insert the hemispherical fixing brackets 11 into the corresponding card slots 134, and the installation position of the plastic optical fiber 12 can be defined by the hemispherical fixing brackets 11.

[0034] Further, the upper shell 13 and the bottom shell 16 are covered to form an accommodation space. The PCBA main board 15 is placed in the accommodation space. The keyboard body 1 further includes a battery 14 (which can be charged through an external power supply). The battery 14 is placed in the accommodation space and is electrically connected to the PCBA main board 15 through a connecting wire. The battery 14 can provide a power source for the overall operation of the keyboard.

[0035] Further, key position symbols are correspondingly provided on the touch keys 136. The provided key position symbols can facilitate the user to touch the desired key position and prevent misoperation.

[0036] In summary, by using the touch keys 136 to replace the traditional mechanical keys, the touchpad 131 can share a PCBA main board 15 with the key core module. At the same time, the lighting part is integrated on the PCBA main board 15, so that the functions of the key core module, the backlight module, the main board and the touchpad 131 can be integrated on one board to complete. This can not only simplify the assembly process and avoid errors, but also save costs, and is worthy of promotion.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
