Description

Technical Field

[0001] This utility model belongs to the technical field of mobile power devices, specifically a mobile power structure with a flight mode that can completely cut off the power supply function of the mobile power supply through a physical switch, thereby improving safety during use and transportation. Background Technology

[0002] In recent years, there have been incidents of portable power banks used to charge mobile communication devices exploding during flights. Currently, most commercially available portable power banks have wireless or wired charging functions, and most cannot completely shut down their internal power systems. Therefore, even when not charging, portable power banks still have standby current, which cannot avoid electromagnetic interference or safety concerns during transportation. Extreme caution must be exercised to avoid improper operation that could lead to flight safety incidents.

[0003] The following are the current regulations of various airlines regarding the carrying and use of power banks: 1. Capacity restrictions: Below 100Wh (approximately 20,000mAh): Can be carried on board, but some airlines limit the number; 100Wh~160Wh (approximately 20,000mAh~32,000mAh): Requires airline approval, with a maximum of 2 units allowed; Over 160Wh: Prohibited from being carried on board. 2. Restrictions on use during flight: Most airlines prohibit the use or charging of power banks during flight. 3. Storage recommendations: Power banks should not be placed in the overhead luggage compartment. It is recommended to place them in your carry-on bag and ensure that the ports are covered or insulated with tape to prevent short circuits. 4. Clear labeling: Many airports and airlines now require power banks to have a Wh (watt) rating or a sticker provided by the brand to be carried on board. Furthermore, portable power banks cannot be placed in checked baggage and can only be placed in carry-on baggage. Especially in air transport or certain sensitive environments, there is a need for devices that can completely shut off the power source. Therefore, specially designed portable power banks are necessary to meet the needs of both airlines and travelers.

[0004] In light of this, the creator, drawing upon years of extensive experience in structural design, has conceived and proposed a mobile power bank structure with a flight mode. This structure features a physical flight mode switch and can completely shut down all output and input terminals. The physical switch controls the switching between two modes: a normal charging mode, allowing the power bank to be used for wired and wireless charging, and a flight mode. When switched, the circuit between the internal battery cells and the charging / discharging connection ports is completely disconnected, shutting down all charging and discharging functions and eliminating standby current. This prevents accidental power-on or charging, reduces the risk of fire or electromagnetic interference, improves safety during use and transportation, and extends battery life. Furthermore, in addition to general civilian mobile power banks, it can also be applied to fields requiring strict electromagnetic interference control, such as medical equipment, aerospace equipment, and military equipment. Utility Model Content

[0005] One objective of this invention is to provide a mobile power bank structure with a flight mode, comprising a housing, a battery unit, and a control circuit board. The battery unit and the control circuit board are housed within the housing.

The first microcontroller has a flight mode switching button, and the second microcontroller has a power button. By quickly and intuitively operating the flight mode switching button, the power supply switch can be controlled, allowing the charging / discharging connection port to be turned on or completely disconnected, thereby improving safety during use and transportation.

Detailed Implementation

[0015] To ensure a clear understanding of the contents of this utility model, please refer to the following description and accompanying drawings.

[0016] Please see Figure 1 , Figure 2 , Figure 3 ,and Figures 4-5 The figures below show exploded perspective views of various aspects of the preferred embodiment of the present invention, as well as its assembled perspective view, its appearance diagram during installation, and its various operational diagrams during use. As shown in the following figures, the mobile power supply structure 1 with flight mode of the present invention includes a housing 11, a battery unit 12, and a control circuit board 13.

[0017] The outer shell 11 is made into a rectangular cube, and the interior of the outer shell 11 is provided with an accommodating space 111, and the accommodating space 111 is provided with a plurality of openings 112 relative to the surface of the outer shell 11.

[0018] The battery unit 12 is generally formed by electrically connecting common lithium battery packs, multiple lithium iron batteries, or safer semi-solid batteries or solid batteries, and is located in the accommodating space 111 for storing and discharging energy.

[0019] The control circuit board 13 is located within the accommodating space 111 and is electrically connected to the battery cell 12. The control circuit board 13 includes a first microcontroller 131, a battery protection circuit 132, a power supply switch 133, a power management chip 134, a second microcontroller 135, at least one charging / discharging connection port 136, and a digital power display module 137. The battery protection circuit 132 and the first microcontroller 131 are connected in parallel and are electrically connected to the battery cell 12 and the power supply switch 133. The power supply switch 133 is electrically connected to the power management chip 134. The power management chip 134 is electrically connected to the second microcontroller 135, the charging / discharging connection port 136, and the digital power display module 137. The first microcontroller 131 is provided with a flight mode switching key 1311, the second microcontroller 135 is provided with a power button 1351, and the digital power display module 137 is provided with an indicator panel 1371. It should be noted that the charging / discharging connection port 136, the flight mode switching key 1311, and the power button 1351 of this utility model are respectively disposed in each of the openings 112, so that each component is separated and exposed on the surface of the housing 11. In this way, it is not easy to accidentally touch or interfere with each other during operation. The charging / discharging connection port 136 is selected from one of the following: TYPE C, USB 2.0, USB 3.0, or wireless charging coil, so wired charging and discharging and wireless discharging can be performed.

[0020] Furthermore, based on the current design and usage of portable power banks, the digital power display module 137 displays the power level in several different ways: First, the digital power display module 137 includes a power detection unit 1372 and a digital display screen 1373. The power detection unit 1372 detects the remaining power of the battery unit 12, and the digital display screen 1373 is located on the surface of the housing 11 and displays the remaining power level on the digital display screen; Second, the digital power display module 137 includes the power detection unit 1372 and... Multiple LED indicator lights 1374 are provided. The power detection unit 1372 detects the remaining power of the battery unit 12. The multiple LED indicator lights 1374 are located on the surface of the housing 11. There are two ways to display this using LEDs. The first is that after the power detection unit 1372 is electrically connected to the multiple LED indicator lights 1374, the corresponding number of LED indicator lights 1374 will light up one by one according to the remaining power. The second is that the multiple LED indicator lights 1374 will emit different colors of light according to the remaining power.

[0021] Accordingly, when operating the mobile power supply structure 1 with flight mode of this utility model, pressing the power button 1351 enables the battery unit 12 to output electrical energy normally to the charging and discharging connection port 136. Alternatively, electrical energy can be input from the outside into the battery unit 12 for storage. When in use, the power level is displayed through the digital power display module 137. When flight mode is desired, operating the flight mode switch button 1311 directly controls the power supply switch 133, completely disconnecting the charging and discharging connection port 136, thereby improving safety during use and transportation. Moreover, its operation is quite intuitive and can be operated immediately without additional instruction.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, any equivalent or easy changes made by those skilled in the art without departing from the spirit and scope of the present utility model should be included within the scope of the present utility model.
