Description

Portable touch interactive keyboard

Technical Field

The invention belongs to the field of electronic products, and particularly relates to a portable touch interactive keyboard.

Background

A keyboard is a device for inputting instructions and data for operating a computer device, and also refers to a set of function keys (e.g., typewriter, computer keyboard) arranged by the system to operate a machine or device.

The keyboard is the most commonly used and main input device, and english letters, chinese characters, numerals, punctuation marks and the like can be input into a computer through the keyboard, so that commands, input data and the like can be sent to the computer. There are also keyboards with various shortcuts. Over time, independent products with various shortcut functions are sold separately in the market, and special driving and setting software is provided, so that personalized operation can be realized on a compatible machine.

With the development of the age, a variety of touch sensors are becoming more accurate, and a user can accurately judge the motion state of a finger by using the touch sensors, and the touch sensitive input device provides more intuitive input options to help the user create more powerful and various input commands.

However, the existing keyboard still has a certain disadvantage in terms of shortcut key input, for example, when a user wants to input a shortcut key with a relatively long key distance such as shift+t+enter, the user has to move the finger from the touch pad to the corresponding shortcut key, and after pressing the shortcut key, the user moves the finger back to the touch pad. Frequently, inputting a shortcut key can lead to a disorder of the rhythm of a user during work, and the input of the shortcut key in such a complex way has violated the original purpose of simplicity and convenience of the shortcut key. Although some keyboards additionally add encoder modules or keys to achieve quick input of combination keys, this approach inevitably leaves the finger from the touch pad area, adding additional limb movement.

Disclosure of Invention

In order to solve the problems, the invention provides the portable touch interactive keyboard, which is characterized in that a touch sensor is embedded in a specific position on a shell, whether a finger touches or slides the specific position of the shell is monitored in real time through the touch sensor, and a specific shortcut combination instruction can be input to external equipment only by touching or sliding the shell with a thumb without moving the finger to open a touch typing area.

The portable touch interactive keyboard is characterized in that: the keyboard comprises a keyboard shell, a touch sensor, a shaft body positioning plate, a circuit board integrating a hot plug socket, RGB lamp beads, a main control chip, a power management module and a communication module, and an upper computer; the touch sensor is embedded with the keyboard housing and electrically connected with the circuit. When the touch sensor is activated, the portable touch interactive keyboard outputs a corresponding shortcut instruction to external equipment.

Further, the touch sensor is integrated on the keyboard shell, and the touch sensor is placed at a position on the keyboard shell where both hands can naturally touch.

Further, the touch sensor is one or a combination of more than two of a capacitive touch sensor, a resistive touch sensor, an ultrasonic touch sensor, an infrared touch sensor and a coding roller type touch sensor.

Further, the touch sensor is a capacitive sensing element.

Further, when the touch sensor is not touched, the magnitude of the sensing capacitor is unchanged, when the touch sensor is touched, the sensing capacitor is changed under the belt, and whether the sensor is touched can be judged by detecting the magnitude of the sensing capacitor.

Further, the touch sensor is an infrared sensing element.

Further, a small hole is formed in a specific position on the keyboard shell, and an infrared sensing element is arranged below the small hole. In a normal state, the infrared echo signal is weak. In case the sensor is touched, the infrared echo signal is enhanced. By comparing the intensity of the infrared echo signals, whether the sensor is touched at the moment can be judged.

Further, the touch sensor is a resistive sensing element.

Further, the communication module is one or a combination of more than two of Bluetooth, a data line, a 2.4G wireless module and a WIFI module and is connected with external equipment.

Further, the RGB lamp beads are arranged under each key cap and are electrically connected with the main control chip.

Further, the shortcut key instruction stored in the current keyboard can be seen through the on-off condition of the upper computer or the RGB lamp beads.

Further, the keyboard can modify the shortcut instruction output to the external device by controlling the combination key through the upper computer or the keyboard.

Further, the number of the touch sensors may be one or more, and the plurality of touch sensors may detect not only whether the finger is touching but also whether the finger is sliding. The plurality of touch sensors may output different shortcut instructions to the external device according to a direction in which the finger slides.

Further, the touch sensor detects that the touch function can be turned on or off through the upper computer or a combination key on the keyboard.

The invention has the beneficial effects that: according to the invention, the specific shortcut key can be conveniently input to the external device by touching or sliding the specific area on the shell under the condition that the hands do not leave the touch pad.

Description of the embodiments

It should be noted that, in the embodiment of the present invention, directional indications (such as up, down, left, right, front, rear, top, bottom, inner, outer, vertical, lateral, longitudinal, counterclockwise, clockwise, circumferential, radial, axial … …) are referred to, and the directional indications are merely used to explain a relative positional relationship, a movement condition, etc. between the next views in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are correspondingly changed.

Touch sensors are embedded in specific locations on the keyboard for detecting hand information on the keyboard housing to enable real-time tracking of an adversary. When the function of the touch sensor for outputting a shortcut key is not activated, touching or sliding the keyboard housing by hand does not have any effect. When the function of outputting a shortcut key by the touch sensor is activated, the keyboard can output a specific shortcut instruction to the external device by touching or sliding the keyboard housing with a hand. Thus, or a convenient and efficient solution to the conventional implementation that requires frequent hand separation from the touch pad when entering a shortcut key.

To prevent false touches (e.g., when a user moves his thumb or makes an unintended touch action), the controller key may be used to perform a touch or slide detection function, in some embodiments the controller may be a combination of "MENU" and "F8" keys on a standard QWERT-style keyboard. In operation, when a user needs to turn on the function, he or she can press the "MENU" key and the "F8" key simultaneously to turn on the function. When the user needs to close the function, the user can close by pressing the MENU key and the F8 key again.

In some embodiments, the user may modify the combination of the currently output shortcut key by combining keys of the "MENU" key with the "F9" key on a standard QWERT-style keyboard. Taking an example of some embodiment, if the shortcut key output by the keyboard is duplicated when the user wants to touch the shell, namely the key of "CTRL" and the key of "F9" are first pressed by the user to enter the editing interface, at this time, the RGB backlight lamps under all keys are turned off, after the key of "CTRL" is pressed by the user, the RGB backlight lamps on the key of "CTRL" are turned from the off state to the normally on state, and similarly, the RGB backlight lamps on the key of "C" are turned from the off state to the normally on state after the key of "C" is pressed by the user. When the user presses the "MENU" key+"≡key, the combination key of the CTRL key plus the C key is stored as a shortcut key output when the user slides left.
