Description

TECHNICAL FIELD

[0001] The present application relates to the field of energy storage power supply, in particular to an energy storage power supply. BACKGROUND

[0002] With the rapid development of new energy technology and the popularity of outdoor lifestyle, portable energy storage power supply is increasingly widely used in camping, emergency power supply and other scenarios. Traditional energy storage power supply is usually equipped with AC output port (such as AC socket), DC output port (such as car charging interface) and USB charging interface, which can supply power to various electronic devices. However, the existing energy storage power supply still has the following problems in actual use:

[0003] (1) In the case of outdoor camping or night emergency, users often need to carry additional lighting equipment (such as flashlight, camping lamp, etc.) to see the position of the output port of the energy storage power supply, otherwise it is difficult to accurately plug in the equipment. This not only increases the carrying burden, but also reduces the convenience of use.

[0004] (2) The traditional energy storage power supply usually needs to turn on the main power switch first, and then manually enable the independent switch of each output port (such as AC switch, DC switch, etc.). This step-by-step operation is inefficient in emergency situations and is prone to power failure due to misoperation.

[0005] (3) In outdoor environment, the output port is easy to be invaded by dust, rain or foreign matter, affecting electrical safety. Although some products use physical flip cover to protect the port, the opening and closing of the flip cover is not linked to the power supply function, and the user may forget to turn on the power, resulting in the device cannot be charged.

[0006] In view of the above problems, some improvement schemes have been proposed in the prior art, for example:

[0007] Add LED lighting lamp on the energy storage power supply, but need to be manually turned on, which cannot be automatically adjusted according to the ambient light;

[0008] Use mechanical switch linked with flip cover, but the structure is complex and the reliability is low;

[0009] Control the output port through APP remotely, but it depends on network and the operation is delayed. CONTENT OF THE INVENTION

[0010] The purpose of the present application is to provide an intelligent energy storage power supply which can automatically detect ambient light to provide lighting and automatically control power supply through flip cover status, thereby simplifying the operation process, improving the convenience of night use, and ensuring the reliability of port protection.

[0011] In order to achieve the above purpose, the present application provides the following technical solutions:

[0012] The energy storage power supply for outdoor or home use comprises a plurality of output ports, an LED lighting assembly and a control circuit, each of the output ports is provided with a protective cover, and a magnet is arranged in the protective cover; a detection module and an MCU are arranged in the control circuit; the detection module comprises a magnetic induction unit for detecting the opening and closing state of the protective cover and a light induction unit for detecting the ambient light intensity; the MCU is configured to automatically enable the corresponding output port when the magnetic induction unit detects that the protective cover is opened and automatically turn on the LED lighting assembly when the light induction unit detects that the ambient light is lower than a threshold.

[0013] Further, the magnet is a strong magnet.

[0014] Further, the magnetic induction unit is a Hall sensor.

[0015] Further, the light induction unit is a photosensitive sensor.

[0016] Further, the protective cover is a protective flip cover.

[0017] Further, the model of the MCU is CY8C6116BZI-F54.

[0018] Further, the energy storage power supply further comprises a main circuit and a control circuit, the main circuit comprises a lithium battery, a BMS protection module, an inverter module, a direct current module, a USB module, an output module and a charging management module; the lithium battery is connected with the BMS protection module and is further connected with the inverter module, the direct current module, the USB module and the charging management module respectively, the inverter module, the direct current module and the USB module are connected with the output module respectively, the control circuit comprises an auxiliary power supply and an LED lamp module; the auxiliary power supply is connected with the BMS protection module and the MCU respectively, the MCU is connected with the LED lamp module and the detection module, and the LED lamp module and the detection module are further connected with the output module respectively.

[0019] Further, the output module comprises an alternating current output port, a direct current output port and a USB output port.

[0020] Further, the inverter module is a bidirectional inverter, and the bidirectional inverter comprises an LLC boost circuit and an H-bridge rectifier circuit.

[0021] The application has the following beneficial effects:

[0022] (1) The application detects the ambient light intensity in real time by setting a light sensing unit (such as a photosensitive sensor), and when the light is lower than the set threshold, the MCU automatically controls the LED lighting assembly to turn on, providing clear port lighting for the user. Users do not need to carry a flashlight or camping lamp to quickly locate the output port in a dark environment, reducing the burden of equipment. Only when the ambient light is insufficient, the lighting is started, avoiding unnecessary power consumption and prolonging the use time of the energy storage power supply.

[0023] (2) The application detects the opening and closing state of the protective cover through a magnetic sensing unit (such as a Hall sensor), and when the user opens the cover, the MCU automatically enables the corresponding output port, eliminating the need for manual switching steps. Users only need to open the protective cover to directly plug in the device for power supply, which is especially suitable for quick response in emergency situations. After closing the cover, the power is automatically turned off to avoid the risk of electric shock or short circuit caused by long-term exposure of the port, and to prevent children from being accidentally touched.

[0024] (3) The protective cover of the application has a dual role: it protects the port from dust and rain erosion, and realizes non-contact switching control through the cooperation of the magnet and the sensor, avoiding mechanical wear. The magnetic sensing unit and the light sensing unit work independently and are cooperatively controlled, with high system stability and low failure rate. BRIEF DESCRIPTION OF DRAWINGS
