Technical Field

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

[0002] An emergency power supply box typically includes a housing, a driver circuit board, and a battery. Both the driver circuit board and the battery are housed within the housing. The driver circuit board is electrically connected to the battery. The battery's input terminal is electrically connected to a first set of connecting wires, used to connect to an external power source to charge the battery. The driver circuit board's output terminal is electrically connected to a second set of connecting wires, used to connect to an LED light to power the LED light. When people go on outdoor adventures, they carry LED lights and LED emergency power supply boxes. However, during use, the power is constantly being consumed, and with prolonged use, the power becomes insufficient to meet their needs. Therefore, people often choose solar-powered emergency power supply boxes.

[0003] Currently used solar emergency power boxes integrate solar panels on top of the box for easy portability. Because the solar emergency power box contains a battery, it is heavy and needs to be carried by hand during movement. To prevent the box from shaking due to the handle's flexibility, the handle is fixed to the box. However, the handle blocks the sunlight from the solar panel, affecting the utilization rate of sunlight. 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 an emergency power box that can adjust the handle position, has high stability, and is highly practical.

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

[0006] An emergency power supply box includes a box body, a solar panel, and a handle;

[0007] The box includes an outer shell, with end caps fixedly installed at both ends of the outer shell. The outer shell and the end caps form a cavity for accommodating emergency components. Input ports and output ports for connecting to emergency components are respectively provided on both sides of the outer shell. A solar panel is fixedly installed on the top of the outer shell.

[0008] The handle is U-shaped; a disc is fixedly installed on the outer side of both end caps, and a pin is fixedly installed on the outer side of each disc. The two ends of the handle are rotatably connected to the pins, and a position locking structure for locking the handle is installed on one of the pins.

[0009] In this way, when used outdoors, the battery in the emergency components can be charged via the solar panel or the input port. The output port is used for power output, and various output port designs are available to meet different output needs. When charging the battery, the position locking mechanism unlocks, and the handle is rotated to one side of the casing to avoid obstructing the solar panel. The position locking mechanism then secures the handle in place. When the emergency power box needs to be moved, the position locking mechanism keeps the handle in a vertical position for easy movement.

[0010] Preferably, the position locking structure includes a locking disc, the pin is provided with a sliding hole along the axial direction, the two ends of the sliding hole are connected to limit holes, the locking disc is fixedly installed with a slider that slides with the sliding hole, the two ends of the slider are fixedly installed with limit blocks that can slide with the limit holes, a tension spring is provided in the sliding hole, one end of the tension spring is fixedly connected to the disc body, and the other end of the tension spring is fixedly connected to the slider;

[0011] Two plugs are fixedly installed on the locking disc, with adjacent plugs set at 180 degrees. The handle has four holes that can be inserted and cooperate with the plugs, with adjacent holes set at 90 degrees.

[0012] Preferably, the outer end of the locking disc has a handle.

[0013] Preferably, four feet arranged in a rectangular pattern are fixedly installed at the lower end of the outer casing.

[0014] Preferably, an emergency light and a switch button are installed on one side of the housing.

[0021] 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.

[0022] like Figure 1-5 As shown, an emergency power supply box includes a box body, a solar panel 1, and a handle 2;

[0023] The box body includes an outer shell 3, with end caps 4 fixedly installed at both ends of the outer shell. The outer shell and the end caps form a cavity for accommodating emergency components. An input port 5 and an output port 6 for connecting to the emergency components are respectively provided on both sides of the outer shell. A solar panel is fixedly installed on the top of the outer shell.

[0024] The handle is U-shaped; a disc body 7 is fixedly installed on the outer side of both end caps, and a pin 8 is fixedly installed on the outer side of each disc body. The two ends of the handle are rotatably connected to the pins, and a position locking structure for locking the handle is installed on one of the pins.

[0025] In this way, when used outdoors, the battery in the emergency components can be charged via the solar panel or the input port. The output port is used for power output, and various output port designs are available to meet different output needs. When charging the battery, the position locking mechanism unlocks, and the handle is rotated to one side of the casing to avoid obstructing the solar panel. The position locking mechanism then secures the handle in place. When the emergency power box needs to be moved, the position locking mechanism keeps the handle in a vertical position for easy movement.

[0026] The emergency components installed within the housing include, in addition to the battery, a charging module. The charging module includes at least a solar module and a lithium battery management module that are electrically connected in the direction of power input and supply power to the battery. The output module of the emergency components includes a DC-DC converter circuit that converts the power stored in the battery into DC output and / or an AC-DC converter circuit that converts the power stored in the power module into AC output. The output port includes an output interface electrically connected to the DC-DC converter circuit and / or the AC-DC converter circuit. The solar charging panel connects to the charging interface of the solar module of the emergency components. The structure of the emergency components is existing; for details, please refer to the solar emergency power supply disclosed in patent CN111371150A. This application does not modify the structure of the emergency components of the solar emergency power supply; this application only aims to improve the utilization rate of sunlight by the solar panel.

[0027] In a specific implementation, the position locking structure includes a locking disc 9, a sliding hole 10 is provided along the axial direction of the pin shaft, and limit holes 11 are provided at both ends of the sliding hole. A slider 12 that slides with the sliding hole is fixedly installed on the locking disc. Limiting blocks 13 that slide with the limit holes are fixedly installed at both ends of the slider. A tension spring 14 is provided in the sliding hole. One end of the tension spring is fixedly connected to the disc body, and the other end of the tension spring is fixedly connected to the slider.

[0028] Two plugs 15 are fixedly installed on the locking disc, with adjacent plugs set at 180 degrees. The handle has four sockets 16 that can be inserted and cooperate with the plugs, with adjacent sockets set at 90 degrees.

[0029] In this way, when the emergency power box needs to be moved, turn the handle to the vertical position. Under the action of the tension spring, the plug will be inserted into the two opposite holes of the handle. When the solar panel needs to be used, pull the locking disc outward. The locking disc will drive the slider to move outward, the tension spring will be stretched, and after turning the handle 90 degrees, the locking disc will be released, the tension spring will return to its original position, and the plug will be inserted into the hole, thus locking the current position of the handle.

[0030] Specifically, a position locking structure is all that is needed to meet the usage requirements. The rotation of the handle is limited by the position locking structure, which is simple and easy to operate.

[0031] In practice, the outer end of the locking disc has a handle for easy hand grip.

[0032] In practice, four rectangularly arranged foot pads are fixedly installed at the lower end of the outer shell to improve wear resistance.

[0033] In a specific implementation, an emergency light 17 and a switch button are installed on one side of the housing. Both the emergency light 17 and the switch button are electrically connected to emergency components, which is an existing structure.

[0034] 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.
