[0002] A Bluetooth keyboard is a keyboard that uses the Bluetooth protocol for wireless transmission and performs Bluetooth communication within an effective range (within 10m). It is actually a short-range radio technology. Using "Bluetooth" technology, it can effectively simplify the communication between mobile communication terminal devices such as PDAs, laptops and mobile phones.

[0011] In a preferred embodiment, guide plates are extended outwardly on both sides of the bottom end of the upper cover, and sliding grooves are provided on both sides of the bottom wall of the mounting groove to meet the needs of the guide plate to slide.

[0012] In a preferred embodiment, one side of the Bluetooth keyboard body also has a charging port.

[0013] To sum up, due to the adoption of the above-mentioned technical scheme, the beneficial effect of the utility model is as follows: a detachable human body sensing module is added to the main body of the Bluetooth keyboard.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] A Bluetooth keyboard with a detachable human body sensing module, referring to Figure 1-3 , including a Bluetooth keyboard body 1, which contains a main control board, the upper surface of the Bluetooth keyboard body 1 is sunken to form a mounting groove 102, a human body sensing module 2, which is detachably mounted in the mounting groove 102 and is electrically connected to the main control board of the Bluetooth keyboard body 1, the human body sensing module 2 includes an upper cover 201, a PCBA main board 204 and a bottom plate 205, the PCBA main board 204 is integrated with a sensor 203, the sensor 203 is an infrared thermoelectric sensor, the human body sensing module 2 is used to detect the surrounding environmental signals, and send them to the main control board of the Bluetooth keyboard body 1, and the main control board detects the environmental signals according to the received signals. The working state of the Bluetooth keyboard body 1 is adjusted according to the information. A detachable human body sensing module 2 is added to the Bluetooth keyboard body 1. When a person approaches the Bluetooth keyboard body 1, the human body temperature is sensed by the sensor 203, and the PCBA mainboard 204 transmits the sensed signal to the main control board (not shown in the figure), and the main control board controls the backlight and the Bluetooth function to be automatically turned on, which can greatly improve the intelligence of the keyboard. At the same time, when the human body leaves the sensing range, the human body sensing module 2 does not receive the human body signal, and the main control board controls the Bluetooth keyboard body 1 to enter sleep immediately, so as to save energy and power.

[0020] Among them, the keyboard's automatic sleep function and automatic backlight function are technologies that have been implemented in current Bluetooth keyboards, and the specific structure and circuit will not be explained here.

[0021] It should also be mentioned that the infrared thermoelectric sensor is an electrothermal converter. Its temperature measurement principle is to use the thermal radiation energy of an object, divide the infrared spectrum into different bands, and convert these bands into electrical signals, thereby realizing the temperature measurement of the target object. When a human body approaches the keyboard, the sensor 203 detects the temperature change and outputs a high level. At this time, the keyboard main control board receives the high level and automatically turns on the backlight and reconnects to the Bluetooth function. When the human body leaves the sensing range, it automatically outputs a low level. At this time, the keyboard MCU (main control board) receives a low level and controls the keyboard to enter sleep immediately.

[0022] Furthermore, a pogopin female socket 101 is embedded in the inner end surface of the installation groove 102, and the pogopin female socket 101 is electrically connected to the main control board through a flat cable. A pogopin male socket 206 that is compatible with the pogopin female socket 101 is also integrated on one side of the PCBA main board 204. By plugging the pogopin male socket 206 and the pogopin female socket 101, the electrical connection between the Bluetooth keyboard body 1 and the human body sensing module 2 can be achieved. When the human body sensing module 2 needs to be disassembled, it can be pulled out to one side.

[0023] Furthermore, one end of the mounting slot 102 extends to the edge of the Bluetooth keyboard body 1 . The above design can facilitate inserting the human body sensing module 2 into the Bluetooth keyboard body 1 or removing it from the Bluetooth keyboard body 1 .

[0024] Furthermore, the upper cover 201 and the bottom plate 205 are fixed by screws or buckles, and the PCBA mainboard 204 is accommodated in the accommodating space formed between the upper cover 201 and the bottom plate 205. A slot for the pogopin male socket 206 to extend is opened on the side of the upper cover 201. A protective cover 202 is provided on the upper cover 201 directly above the sensor 203. The protective cover 202 can protect the internal sensor 203. The protective cover 202 is preferably made of transparent plastic material, but is not limited to the above material.

[0025] Furthermore, guide plates 207 are extended outward on both sides of the bottom end of the upper cover 201, and sliding grooves are provided on both sides of the bottom wall of the installation groove 102 to meet the guiding sliding of the guide plate 207. Through the cooperation of the sliding grooves and the guide plates 207, an auxiliary guiding effect can be played for the installation of the human body sensing module 2 to ensure the docking accuracy of the pogopin female seat 101 and the pogopin male seat 206. Secondly, the upper and lower positions of the human body sensing module 2 can be limited to ensure the strength after installation.

[0026] Furthermore, one side of the Bluetooth keyboard body 1 also has a charging interface 103, and the interior of the Bluetooth keyboard body 1 also accommodates a battery electrically connected to the charging interface 103 and the main control board. The charging interface 103 can be used to charge the battery, and the charging interface 103 can be connected to AC power or a power supply to charge the battery, thereby providing a power source for the overall operation of the Bluetooth keyboard body 1.

[0027] Among them, the charging interface 103 is preferably a USB interface, but is not limited to the above interface.

[0028] To sum up, a detachable human body sensing module 2 is added to the Bluetooth keyboard body 1. When a person approaches the keyboard, the human body temperature is sensed by the human body sensing module 2, and the sensed signal is transmitted to the main control board of the Bluetooth keyboard body 1. The main control board is used to control the automatic lighting of the backlight and the reconnection to the Bluetooth function, which can greatly improve the intelligence of the keyboard.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
