Description

Technical Field

[0001] This utility model relates to the field of emergency power supply technology, and in particular to a portable emergency power supply. Background Technology

[0002] Portable emergency power supplies are widely used in emergency response, environmental protection, power, medical, and telecommunications industries, solving the problem of emergency power supply for various instruments and equipment outdoors and becoming the best supporting role in outdoor work. They can ensure continuous operation of equipment even when outdoor power sources are difficult to access, inconvenient to use, or the equipment itself has insufficient power, ensuring the smooth conduct of outdoor rescues and drills.

[0003] When used outdoors, the emergency power supply needs to be moved to the required location, hence the handle installed on it. There are two installation methods for the handle: 1. Vertical installation: directly fixed to the outer casing of the emergency power supply, resulting in a large space occupation; 2. Rotating installation: the handle is rotatably connected to the outer casing of the emergency power supply, allowing it to rotate freely relative to the power supply. However, because the power supply contains batteries and other circuit components, it is heavy and prone to wobbling when moved, exhibiting poor stability and causing significant inconvenience and portability, failing to meet usage requirements. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a portable emergency power supply with a simple and reasonable structure, high stability and convenient use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A portable emergency power supply includes a housing and a handle, wherein a circuit is installed inside the housing, and an input port and an output port connected to the circuit are installed on the housing;

[0007] The handle includes two symmetrically arranged grips, each grip being U-shaped, with both ends of the grip serving as mounting ends. The outer shell has two mounting slots for accommodating the grips. A limiting block is formed between the opposite ends of the two mounting slots. The mounting ends of the grips are rotatably connected to the outer shell, and a limiting opening is formed between the mounting ends of the grips and the limiting block. When the grip is rotated to a vertical position, the limiting block and the limiting opening are engaged.

[0008] In this way, during use, the two handles rotate into the mounting slots, making the top of the emergency power supply flat and minimizing its space occupation. When it is necessary to move the emergency power supply, rotate the two handles to a vertical position, where they fit together to form a handle. Simultaneously, the limiting block aligns with the limiting opening, allowing the emergency power supply to be moved by holding the handles. Because the limiting block aligns with the limiting opening, and the two handles are located on either side of the limiting block, rotation of the handles in opposite directions is restricted, keeping the positions of the handles and the emergency power supply relatively fixed, facilitating movement. The battery is charged through the input port, and the output port is used for power output. Various output port designs are available to meet different output requirements.

[0009] Preferably, the mounting end of the grip is provided with a through hole, and the outer shell is provided with a through hole and a threaded hole opposite to the through hole. The through hole is located outside the through hole, and the bolt passes through the through hole and the through hole and is connected to the threaded hole.

[0010] Preferably, magnets with opposite polarities are fixedly installed on the two handles respectively, and the two magnets attract each other when the two handles are in contact.

[0011] Preferably, the outer shell has a clearance notch facing the grip.

[0012] Preferably, the outer casing has heat dissipation holes.

[0013] In summary, this portable emergency power supply has the advantages of simple and reasonable structure, high stability, and ease of use. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0019] like Figure 1-4 As shown, a portable emergency power supply includes a housing 1 and a handle. A circuit is installed inside the housing, and an input port 2 and an output port 3 connected to the circuit are installed on the housing.

[0020] The handle includes two symmetrically arranged grips 4, each grip being U-shaped, with both ends of the grip serving as mounting ends; the outer shell has two mounting grooves 5 for accommodating the grips; a limiting block 6 is formed between the opposite ends of the two mounting grooves; the mounting ends of the grips are rotatably connected to the outer shell, and a limiting opening 7 is formed between the mounting ends of the grips and the limiting block; when the grip is rotated to a vertical position, the limiting block and the limiting opening are engaged.

[0021] In this way, during use, the two handles rotate into the mounting slots, making the top of the emergency power supply flat and minimizing its space occupation. When it is necessary to move the emergency power supply, rotate the two handles to a vertical position, where they fit together to form a handle. Simultaneously, the limiting block aligns with the limiting opening, allowing the emergency power supply to be moved by holding the handles. Because the limiting block aligns with the limiting opening, and the two handles are located on either side of the limiting block, rotation of the handles in opposite directions is restricted, keeping the positions of the handles and the emergency power supply relatively fixed, facilitating movement. The battery is charged through the input port, and the output port is used for power output. Various output port designs are available to meet different output requirements.

[0022] In specific implementation, the mounting end of the grip has a through hole 8. The outer shell has a through hole and a threaded hole opposite the through hole. The through hole is located outside the through hole. The bolt 9 passes through the through hole and the through hole and connects to the threaded hole. By connecting the grip to the outer shell with the bolt, the mounting end of the grip can rotate relative to the bolt, facilitating quick assembly. In actual installation, a thread can be provided at the end of the bolt, leaving the rest of the bolt with a smooth shaft, which also facilitates the rotation of the grip.

[0023] In practice, magnets 10 with opposite polarities are fixedly installed on each of the two grips. When the two grips are placed together, the two magnets attract each other, making the grips more stable when they are in contact. The two magnets with opposite polarities, namely the S pole and the N pole, are able to attract each other.

[0024] In a specific implementation, the outer shell has a clearance notch 11 facing the handle, which facilitates rotating the handle outward from the receiving groove.

[0025] In specific implementation, the outer casing is provided with heat dissipation holes 12 to facilitate heat dissipation during use of the emergency power supply.

[0026] The circuit includes a power supply module, a charging module, and an output module. The power supply module includes at least one detachable lithium battery pack. The charging module is used to charge the lithium battery pack and is connected to the input port. The output module is used to convert the electrical energy from the lithium battery pack into DC output via a DC-DC converter circuit and / or to convert the electrical energy stored in the power supply module into AC output via an AC-AC converter circuit, and is connected to the output port. The circuit structure is existing; for details, please refer to the solar emergency power supply disclosed in patent CN111371150A. This application does not modify the circuit of the emergency power supply; this application is only for improving the portability of the emergency power supply.

[0027] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
