Description

Technical Field

[0001] The utility model relates to the technical field of keyboards, in particular to a keyboard with an earthquake reminder function. Background Art

[0002] An earthquake is a phenomenon in which a local rupture of the earth's internal medium generates shock waves, which causes ground vibrations within a certain range. The acceleration of gravity also changes within a certain range, and the direction of the geomagnetic field also changes. Earthquakes often cause serious casualties and damage to buildings and other engineering facilities, especially in public places and densely populated areas, which are more likely to cause serious losses. Therefore, earthquake warnings are particularly important.

[0003] With the development of science and technology, mobile phones are all equipped with earthquake reminder functions, making earthquake reminders more convenient.

[0004] However, there are still some groups whose mobile phones are out of the work area or in silent mode during work, and they cannot receive earthquake alarm reminders in time. Computer equipment is an indispensable equipment at work, so a keyboard with earthquake reminder function is provided. Utility Model Content

[0005] In order to solve the technical defects in the prior art and to promptly remind working personnel of the occurrence of an earthquake, the utility model provides a keyboard with an earthquake reminder function, including a keyboard, on which an earthquake display light and an alarm horn are arranged, the earthquake display light and the alarm horn are electrically connected to a PCB board with an MCU, and a Bluetooth module is also arranged on the PCB board.

[0006] Furthermore, four bar-shaped holes are arranged in sequence on the keyboard.

[0007] Furthermore, the earthquake display light is installed in the strip-shaped hole, and the earthquake display light is a strip-shaped LED light.

[0008] Furthermore, the keyboard is provided with a sound amplification hole.

[0009] Furthermore, the alarm speaker is installed below the sound amplification hole.

[0010] In summary, the beneficial effects of the utility model include providing a keyboard with an earthquake reminder function, which has a simple structure and can promptly remind working personnel of the occurrence of an earthquake. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Example 1: Reference Figure 1-2As shown, the utility model provides a keyboard with an earthquake reminder function, including a keyboard 1, on which an earthquake display light 2 and an alarm speaker 3 are arranged, and the earthquake display light 2 and the alarm speaker 3 are electrically connected to a PCB board 5 with an MCU4, and a Bluetooth module 6 is also arranged on the PCB board 5.

[0020] Furthermore, four strip-shaped holes 11 are arranged in sequence on the keyboard 1 .

[0021] Furthermore, the earthquake display light 2 is installed in the strip-shaped hole 11, and the earthquake display light 2 is a strip-shaped LED light.

[0022] Furthermore, the keyboard 1 is provided with a sound amplification hole 12 .

[0023] Furthermore, the alarm speaker 3 is installed below the sound expansion hole 12 .

[0024] Specifically, based on the existing keyboard 1 structure, the width of the keyboard 1 is widened, and four strip holes 11 are arranged in sequence above the indicator light area above the numeric keys. Earthquake display lights 2 are installed in sequence in the four strip holes 11. The earthquake display lights 2 are strip LED lights for displaying different earthquake magnitudes. For example, if the earthquake magnitude is weak, one strip LED light is lit, if the earthquake magnitude is felt, two strip LED lights are lit, if the earthquake magnitude is medium-strong, three strip LED lights are lit, and if the earthquake magnitude is strong, four strip LED lights are lit.

[0025] A sound amplification hole 12 is provided on the right side of the strip hole 11 , and an alarm speaker 3 is installed inside the keyboard below the sound amplification hole 12 .

[0026] The earthquake display light 2 and the alarm speaker 3 are electrically connected to the PCB board 5 through wires, and are connected to the MCU4 through the lines on the PCB board 5. The MCU adopts STM32C0. A Bluetooth module 6 is also provided on the PCB board 5, and its model is EW-M0D02. EW-M0D02 supports broadcast mode, and the Bluetooth module 6 is also connected to the MCU4 through the lines on the PCB board 5.

[0027] In the application, for the staff who need to mute their mobile phones, they can connect to the mobile phone through the Bluetooth module 6. When the mobile phone receives an earthquake reminder, the MCU4 receives the earthquake reminder information through the Bluetooth module 6, and determines the magnitude of the earthquake based on the content of the earthquake reminder information, so as to control the number of earthquake display lights 2 that light up, and at the same time control the alarm speaker 3 to emit a buzzer to remind the personnel in the working state.

[0028] For workers who need to temporarily store their mobile phones away from the work area, the EW-M0D02 Bluetooth module 6 supports broadcast mode and can also receive earthquake broadcasts.

[0029] The PCB board 5 is electrically connected to the circuit board of the keyboard 1 through wires, so as to provide power to the PCB board 5 and the components on the board.

[0030] The installation method of the PCB board 5 in the keyboard is prior art and will not be described in detail.

[0031] In summary, the beneficial effects of the utility model include providing a keyboard with an earthquake reminder function, which has a simple structure and can promptly remind working personnel of the occurrence of an earthquake.

[0032] For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
