[0025] In order to make the purpose, technical solution and advantages of the present application clearer, the specific embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. It is understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for the sake of ease of description, only the parts related to the present application are shown in the accompanying drawings, rather than all the contents.

[0026] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] Figure 1 A principle block diagram of a human body sensing keyboard provided in an embodiment of the present application is given, referring to Figure 1 The human body sensing keyboard includes a circuit board body 1, a main control module 2, a detection module 3 and a sensing electrode sheet 4.

[0028] Among them, a routing area is set on the circuit board body 1, and a detection area is set on the circuit board body 1 and / or outside the circuit board body 1. For example, the detection area can be set on the circuit board body 1, and the detection area can also be set at a position outside the circuit board body 1, or the detection area can be set on the circuit board body 1 and at a position outside the circuit board body 1 at the same time. Figure 1 As shown, the range corresponding to the solid line frame S11 in the figure is the routing area, the range corresponding to the solid line frame S21 is the detection area set on the circuit board body 1, and the dotted line frame S22 is the detection area set outside the circuit board body 1.

[0029] The human body sensing keyboard provided in this solution can be a wired keyboard, a wireless keyboard, or a keyboard with both wired and wireless connection functions, and the main control module 2 is connected to or has one or more corresponding communication modules built in. The main control module 2 can be connected to an external device (such as a mobile phone, a computer, etc.) through the communication module based on the set communication protocol, and send corresponding keyboard operation information to the external device.

[0030] The main control module 2 and the detection module 3 provided in this solution are installed in the wiring area, the sensing electrode sheet 4 is installed in the detection area, and the sensing electrode sheet 4 is connected to the detection module 3, and the detection module 3 is connected to the main control module 2.

[0031] In one embodiment, the sensing electrode sheet 4 provided in the present solution can be an electrode sheet that is copper-clad on the circuit board body 1 and is connected to the circuit board body 1 through a wire. By arranging the sensing electrode sheet 4 on the electrode sheet that is copper-clad on the circuit board body 1, the integrity and stability of the circuit board body 1 are improved.

[0032] In one embodiment, copper grounding can be set in the routing area of ​​the circuit board body 1. The copper grounding can effectively enhance the anti-interference ability of the keyboard, reduce the external radiation of the keyboard, and ensure the stable operation of the keyboard.

[0033] In one embodiment, the detection area provided by the present solution is set on the keyboard housing. For example, the detection area set outside the circuit board body 1 can be set on the inner side and / or outer side of the keyboard housing, and connected to the circuit board body 1 through a wire. By setting the detection area on the keyboard housing, when the user uses the keyboard, the distance between the sensing electrode sheet 4 and the human body can be effectively shortened, thereby improving the sensitivity and accuracy of the sensing electrode sheet 4 in detecting the human body.

[0034] Furthermore, the detection module 3 can be used to detect a human body through the sensing electrode sheet 4 and send human body detection information to the main control module 2. For example, when a human body approaches the sensing electrode sheet 4, the capacitance of the sensing electrode sheet 4 changes, causing the voltage value detected by the port connected to the sensing electrode sheet 4 in the detection module 3 to change. Based on this, the detection module 3 can determine whether a human body is approaching the sensing electrode sheet 4 according to the change in the voltage value of the port connected to the sensing electrode, and output human body detection information indicating to the main control module 2 whether a human body is detected or not.

[0035] The main control module 2 provided in this solution can work in working mode and sleep mode respectively. In the working mode, the main control module 2 can output corresponding keyboard operation information in response to the user's keyboard input operation on the keyboard. In the sleep mode, the keyboard stands by with lower power consumption (for example, reducing the power supply voltage of some functional modules and electrical components, cutting off the power supply to some functional modules and components, etc.) until awakened.

[0036] The main control module 2 provided in this solution can also be used to receive human body detection information sent by the detection module 3, and when the keyboard is in sleep mode (in sleep mode, the keyboard is in standby mode with lower power consumption than that in working mode), upon receiving human body detection information indicating that a human body has been detected, a set wake-up action is performed based on the human body detection information indicating that a human body has been detected. Among them, after the main control module 2 executes the set wake-up action, the keyboard switches from sleep mode to working mode, and the user does not need to actively tap the keys on the keyboard to wake up the keyboard. The user can directly perform keyboard input operations after approaching the keyboard, realizing automatic wake-up of the keyboard without feeling. The keyboard wake-up speed is higher, which can effectively solve the problem in the related technology that when the user tries to wake up the keyboard, the keyboard will respond to the operation of the key to output the corresponding character, and the user also needs to roll back or cancel the character, effectively improving the user experience.

[0037] Optionally, when the main control module 2 performs a set wake-up action based on the human body detection information indicating that a human body has been detected, it can also execute one or more set operations. The set operation can be to turn on or off a light module (such as a keyboard light, indicator light, etc.) installed on the keyboard and connected to the main control module 2 for a lighting prompt, or it can be a set voice prompt using a speaker installed on the keyboard and connected to the main control module 2.

[0038] The main control module 2 provided in the present solution can also be used to execute a set sleep action based on human body detection information indicating that a human body is not detected. Exemplarily, when the main control module 2 receives human body detection information indicating that a human body is not detected and detects a keyboard input operation on the keyboard within a set time length, it executes a set sleep action to switch the keyboard from a working mode to a sleep mode, thereby reducing the power consumption of the keyboard, and realizing automatic sleep when the keyboard is not in use and automatic wake-up when in use, thereby achieving the effect of autonomous power saving while ensuring the normal use of the keyboard.

[0039] In a possible embodiment, the present solution sets a distance between the wiring area and the detection area of ​​the circuit board body 1, so that an insulating area is formed between the wiring area and the detection area of ​​the circuit board body 1. Figure 1 An insulating area is provided between the wiring area S11 and the detection area S21. This solution effectively reduces the interference of components in the wiring area on the sensing electrode sheet 4 on the wiring area by providing an insulating area S31 between the wiring area S11 and the detection area S21 of the circuit board body 1, improves the accuracy of human body detection, ensures that the keyboard correctly enters the sleep mode and wakes up from the sleep mode, and improves the user experience.

[0040] In one possible embodiment, Figure 2 As shown in the schematic diagram of the first detection area setting, the detection area provided by this solution can be arranged in a ring shape on the periphery of the circuit board body 1. Figure 2The detection area S23 is a continuous area, which surrounds the periphery of the circuit board body 1 and surrounds the wiring area S13 on the circuit board body 1, and an insulating area S33 (the shaded area in the figure) is formed between the detection area S23 and the wiring area S13. This solution arranges the detection area in a ring around the periphery of the circuit board body 1, so that the sensing electrode sheet 4 can be installed around the periphery of the circuit board body 1, which is conducive to the installation and layout of various components in the wiring area on the circuit board body 1, and improves the installation and development efficiency of the circuit board body 1.

[0041] In one embodiment, the detection area provided by the present solution may be single or multiple. When setting multiple detection areas, the shapes and sizes of different detection areas may be the same or different, and the distances between different adjacent detection areas may be the same or different. Optionally, one or more sensing electrode sheets 4 may be installed in one or more detection areas, respectively. For example, the number and installation positions of the sensing electrode sheets 4 may be flexibly determined in the detection area according to the range, angle, and sensitivity requirements for human body detection. Optionally, the sensing electrode sheets 4 may be installed in all detection areas, or in some of the detection areas. By installing one or more sensing electrode sheets 4 in the detection area, the installation flexibility of the sensing electrode sheets 4 is improved, and the flexibility of human body sensing detection is improved.

[0042] In one possible embodiment, Figure 3 As shown in the schematic diagram of the second detection area setting, the present solution provides a plurality of detection areas, and the plurality of detection areas are arranged at intervals in a ring shape on the periphery of the circuit board body 1 .

[0043] Figure 3 The detection area is a plurality of intermittent detection areas S24, and the plurality of detection areas S24 are arranged around and at intervals on the periphery of the circuit board body 1, and the plurality of surrounding detection areas S24 surround the wiring area S14 on the circuit board body 1, and an insulating area S34 (the shaded area in the figure) is formed between the plurality of surrounding detection areas S24 and the wiring area S14. This solution arranges a plurality of detection areas at intervals in a ring around the periphery of the circuit board body 1, so that the sensing electrode sheet 4 can be installed around the periphery of the circuit board body 1, which is conducive to the installation and layout of various components in the wiring area on the circuit board body 1, improves the installation and development efficiency of the circuit board body 1, and the detection areas arranged at intervals can avoid the positions where components or wiring need to be installed in the circuit board body 1, and the circuit layout of the circuit board body 1 is more flexible.

[0044] In one possible embodiment, Figure 4 As shown in the schematic diagram of the third detection area setting, the present solution provides a plurality of detection areas, and the plurality of detection areas are arranged at intervals in the middle of the circuit board body 1 . Figure 4 Multiple detection areas S25 are surrounded by the wiring area S15, and an insulating area S35 (the shaded area in the figure) is formed between each detection area S25 and the wiring area S15. This solution arranges multiple detection areas at intervals in the middle of the circuit board body 1, but the distribution of the detection areas is more uniform, which effectively improves the sensitivity of human body detection and detects the human body more accurately. In addition, a large area of ​​copper can be laid on the circuit board body 1, which effectively enhances the anti-interference ability of the keyboard, reduces the external radiation of the keyboard, and ensures the stable operation of the keyboard.

[0045] As mentioned above, by installing the main control module 2 and the detection module 3 in the routing area of ​​the circuit board body 1, installing the sensing electrode sheet 4 in the detection area, connecting the sensing electrode sheet 4 and the detection module 3, and connecting the detection module 3 and the main control module 2, the detection module 3 can perform human body detection through the sensing electrode sheet 4 and send human body detection information to the main control module 2. The main control module 2 can execute the set wake-up action based on the human body detection information indicating that a human body has been detected, and actively wake up the keyboard when a human body is detected. There is no need for the user to actively tap a key to wake up the keyboard, which effectively improves the keyboard wake-up efficiency.

The present application is not limited to the specific embodiments provided herein, and various obvious changes, readjustments and substitutions that can be made by those skilled in the art will not deviate from the scope of protection of the present application.
