In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0015] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intermediate element at the same time. On the contrary, when an element is said to be "directly" connected to another element, there is no intermediate element.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0017] See also Figure 1: A mobile power supply with a warning function, comprising a control module 1, a human body sensor 2, a mode switching button 3, a Bluetooth module 4, an input charging interface 5, an output charging interface 6, a battery 7, a power switch 9 and a sound module 10, wherein the human body sensor 2, the mode switching button 3, the input charging interface 5, the output charging interface 6, the battery 7, the power switch 9 and the sound module 10 are electrically connected to the control module 1 respectively, the signal output end of the control module 1 is connected to the signal input end of the Bluetooth module 4, and the signal output end of the Bluetooth module 4 is connected to the signal input end of an external handheld device 200.

[0018] In one embodiment, the mobile power supply with warning function further includes a light component 8, and the light component 8 is electrically connected to the control module 1 for providing an alarm prompt.

[0019] In one embodiment, the lighting assembly 8 includes an energy-saving lamp or an LED lamp.

[0020] In one embodiment, the human body sensor 2 includes a radar sensor, an infrared sensor, or a human body proximity sensor.

[0021] In one embodiment, the control module 1 includes a single chip microcomputer or an MCU module.

[0022] Turn on the power switch 9, and the mobile power supply starts working. The control module 1 is a single-chip microcomputer or MCU module. The control module 1 is installed on a circuit board. The circuit board has a charging circuit and a power supply circuit. The battery 7 is a rechargeable battery. The input charging interface 5 is connected to an external charging device. The current charges the battery 7 through the input charging interface 5 and the charging circuit on the circuit board. When it is necessary to charge an external device, the external device to be charged is connected to the output charging interface 6, and the battery 7 releases electricity to charge the external device through the power supply circuit and the output charging interface 6. The sound module 10 can be a sounder or a speaker. When a person or other moving object is found approaching, the control module 1 can control the sound module 10 to emit a preset sound, which can serve as a warning.

[0023] The mobile power supply of the present application has two modes, namely night mode, alarm mode and controlled switch mode. Use the mode switch button 3 to switch. When the mobile power supply 100 is in the controlled switch mode, the human body sensor 2 is not enabled and can be used as an ordinary mobile power supply. For example, the night mode is represented by the binary number "0", and the alarm mode is represented by the binary number "1". The mode is switched by pressing the mode switch button 3. When the control module 1 receives "0", it switches to the night mode, and when it receives "1", it switches to the alarm mode.

[0024] When the mobile power supply 100 is in the alarm mode, for example, the mobile power supply 100 is placed at the entrance of a hotel or an outdoor tent, when the human body sensor 2 detects that a human body or other animal is approaching, a detection signal is sent to the control module 1, and the control module 1 sends an alarm signal to the user's mobile phone through the Bluetooth module 4 to remind the user that a person or animal is approaching.

[0025] When the mobile power supply is in night mode; for example, the mobile power supply is placed at the bedside, the user can wave his arm at a close distance, and when the human body sensor 2 sends a human body signal to the control module 1, the control module 1 can light up the light component 8 to play a lighting role, making the mobile power supply more versatile. The light component 8 includes an energy-saving lamp or an LED lamp, which can play a better energy-saving role. The light component 8 is powered by a battery 7.

[0026] In this way, a mobile power supply with an alarm function is provided through the coordinated arrangement of the control module 1, the human body sensor 2, the mode switching button 3, and the Bluetooth module 4. When the mode switching button 3 is pressed to send a control signal to the control module 1, the mobile power supply is in the alarm mode. The mobile power supply 100 is placed at the entrance of a hotel or an outdoor tent. When the human body sensor 2 detects that a human body or other animals are approaching, the control module 1 controls the Bluetooth module 4 to send an alarm signal to the user's mobile phone to remind the user that other people are approaching, which plays a certain safety warning role and makes the mobile power supply 100 more functional.

[0027] In one embodiment, the human body sensor 2 includes a radar sensor, an infrared sensor, or a human body proximity sensor.

[0028] Doppler radar is a special radar that uses the Doppler effect principle to measure the speed of targets at different distances. It transmits microwave signals to a given target and then analyzes the frequency changes of the reflected signal. The difference between the transmitted frequency and the reflected frequency can accurately measure the target's speed relative to the radar and other information.

[0029] Infrared sensors are sensors that use the physical properties of infrared rays to perform measurements. Infrared rays, also known as infrared light, have properties such as reflection, refraction, scattering, interference, and absorption. Any substance, as long as it has a certain temperature (above absolute zero), can radiate infrared rays. When measuring, infrared sensors do not come into direct contact with the object being measured, so there is no friction, and they have the advantages of high sensitivity and fast response.

[0030] The human proximity sensor is a sensor based on the microwave Doppler principle, with a planar antenna as the sensing system and a microprocessor as the control. The human proximity sensor transmits and receives at a microwave frequency of 10.525GHz. The key components of the whole machine are all imported devices. The design and selection of devices ensure the reliability of the product. It adopts non-contact detection, stable performance and long life. The sensor is not affected by temperature, humidity, noise, airflow, dust, light, etc., and is suitable for harsh environments. It has strong anti-RF interference ability and strong penetration ability. It is small in size and easy to install flexibly.

[0031] In one embodiment, the control module 1 includes a single chip microcomputer or an MCU module. The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and utility model concept of the utility model, shall be covered by the protection scope of the utility model.
