Description

Technical Field

[0001] The invention relates to the field of flashlights and mobile power sources, and in particular to a modular device with mobile power source and flashlight functions. Background Art

[0002] Currently, there is a combination of a flashlight and a mobile power source. Since the parts in the combination that are only used for the flashlight function cannot be disassembled, the user has to carry the parts that are only used for the flashlight function when only using the mobile power source, which reduces portability.

[0003] Currently, there is a type of USB flashlight lamp head, which is connected to the USB output interface of a mobile power supply to form a flashlight. The USB flashlight lamp head is detachable, and the user only needs to move the power supply without carrying the USB flashlight lamp head, thereby improving portability; however, most USB flashlight lamp heads do not have a dimming function, which brings inconvenience to the user. The current solution is to set a button and a dimming circuit on the USB flashlight lamp head, which increases the cost; since the USB flashlight lamp head will occupy a USB output interface, a mobile power supply with only a single USB output interface cannot charge a mobile device at the same time after connecting the USB flashlight lamp head, which brings inconvenience to the user; since the USB flashlight lamp head and the mobile power supply are separately designed and randomly combined, the shape and weight of the mobile power supply and the USB flashlight lamp head are uncertain, and the shape and weight of the flashlight may not be suitable for the user to hold, and the shape of the flashlight may not be beautiful; this type of USB flashlight lamp head is only fixed to the mobile power supply through the USB output interface. When the user runs with the flashlight in his hand, the USB flashlight lamp head is easy to fall off from the mobile power supply, which brings inconvenience to the user. Summary of the invention

[0004] The present invention provides a modular device with mobile power supply and flashlight functions, which solves the deficiencies of the above background technologies.

[0005] The technical solution adopted by the present invention is:

[0006] A modular device with mobile power supply and flashlight functions comprises a mobile power supply and a flashlight module. The mobile power supply is provided with a charging interface for connecting an external power supply and the flashlight module. The flashlight module is connected to the mobile power supply to form a flashlight.

[0007] The mobile power supply is provided with a charging circuit and a battery. The charging interface is connected to an external power supply to power the charging circuit. The mobile power supply realizes the power supply, switching and dimming of the flashlight module through the charging interface. The charging interface is a USB-Type-C female connector, and the flashlight module is provided with a corresponding USB-Type-C male connector.

[0008] The mobile power supply is equipped with an MCU, a button, and a power display LED. The MCU, the button, and the power display LED are used to display the remaining power of the mobile power supply; the button and the MCU are also used to switch and dim the flashlight; the MCU is also used to detect whether a flashlight module is connected to the mobile power supply.

[0009] An iron sheet is arranged at one end of the mobile power source where the charging interface is arranged, and a magnet sheet is arranged in the flashlight module. In the flashlight, the magnet sheet attracts the iron sheet, so that the flashlight module is adsorbed on the mobile power source.

[0010] The side profile of the mobile power supply is a rounded rectangle or a circle. In the flashlight, the side of the flashlight module provided with a USB-Type-C male connector overlaps with the side of the mobile power supply provided with a USB-Type-C female connector.

[0011] The beneficial effects of the present invention are:

[0012] The present invention solves the problem of combining a flashlight and a mobile power source; a flashlight module is connected to a mobile power source to form a flashlight; the flashlight module is detachable; when a user only needs the mobile power source, the user does not need to carry the flashlight module, thereby improving portability.

[0013] The invention solves the problem of a USB flashlight lamp head. A flashlight module is connected to a mobile power source to form a flashlight. A button and an MCU in the mobile power source are used to display the remaining power of the mobile power source and are also used to switch and dim the flashlight. It is not necessary to set a separate button and dimming circuit on the flashlight module, thereby reducing the cost. The charging interface of the mobile power source is used to connect an external power source and the flashlight module. It is not necessary to set an interface for connecting the flashlight module separately. The appearance is more concise and beautiful. The USB output interface on the mobile power source is not occupied. The user can use the flashlight function and the mobile power source function at the same time. Since the flashlight module and the mobile power source module are designed together, the weight of the flashlight is within 200g. The mobile power source is used as a handheld part of the flashlight. Its side shape is a rounded rectangle or a circle. The shape and weight of the flashlight are suitable for handholding and are more beautiful. An iron sheet is arranged at one end of the mobile power source where the charging interface is arranged. A magnet sheet is arranged in the flashlight module. When the flashlight module is connected to the mobile power source, the magnet sheet in the flashlight module attracts the iron sheet in the mobile power source, thereby preventing the flashlight module from falling off easily.
