[0029] The present invention will be further described below in conjunction with specific embodiments:

[0030] An outdoor battery pack includes a battery pack body 1, in which a battery pack 2 is arranged. The battery pack body 1 is provided with at least one output port 5, and a transformer module 4 is provided between the battery pack 2 and the output port 5. The transformer module 4 is electrically connected to the battery pack 2 and outputs voltage through the output port 5. The battery pack body 1 is also provided with a voltage regulating switch 6. Driving the voltage regulating switch 6 can control the transformer module 4 to regulate the voltage, thereby adjusting the working voltage output by the battery pack 2.

[0031] The present invention discloses an outdoor battery pack which can be used outdoors and can be adapted to supply power to lithium-ion tools of different voltages. The battery pack has a battery group 2 inside and has a long battery life. A transformer module 4 is provided inside a battery pack body 1. The transformer module 4 is connected to the battery group 2 and can transform the uniform working voltage of the battery group 2. A voltage regulating switch 6 and an output port 5 are provided on the battery pack body 1. The output port 5 can output the electricity transformed by the transformer module 4. When the user connects the battery pack on the lithium-ion tool to the output port 5, the transformer module 4 can output the transformed voltage through the output port 5. The battery pack can provide stable power support for these lithium-ion tools of different voltages, and there is no need to carry a variety of power adapters of different specifications, which greatly improves the convenience of use. The voltage regulating switch 6 can accurately control the working state of the transformer module 4 to avoid damage to the equipment due to excessively high or low voltage.

[0032] Preferably, a display module is provided on the battery pack body 1, and the display module includes a circuit board 7 and a display screen 8. The circuit board 7 is electrically connected to the transformer module 4 and can display the working voltage in real time. The design of the display module allows the user to understand the voltage condition of the current working voltage after the transformer module 4 adjusts the voltage in real time, and it is convenient to observe the voltage value on the display screen 8.

[0033] Preferably, the voltage regulating switch 6 is a button switch or a knob switch. When the voltage regulating switch 6 is a button switch, the voltage is changed by pressing it, and the circuit board 7 of the inner panel is changed into electricity with different working voltages according to the system settings. When the voltage regulating switch 6 is a knob switch, different working voltages can be changed by rotating different angles according to the set settings.

[0034] Preferably, a heat dissipation device 10 is provided in the battery pack body 1, and a plurality of heat sinks 11 are provided in the heat dissipation device 10. Gaps are set between the heat sinks 11, and the heat sinks 11 are stacked layer by layer. The heat sinks 11 are made of metal, which is essential for ensuring the normal operation of the battery pack 2 and extending its service life. The stacked heat sinks 11 in the heat dissipation device 10 greatly increase the heat dissipation area. When the battery pack 2 generates heat during operation, these heat sinks 11 can quickly absorb the heat and dissipate the heat to the surrounding environment through their own large surface area. Air can flow between the heat sinks 11 to form good convection, accelerate the dissipation of heat, and the metal material has good thermal conductivity.

[0035] Preferably, a cooling fan 13 is further provided in the battery pack body 1. The cooling fan 13 is arranged above the heat sink 11. The blades in the cooling fan 13 are facing the heat sink 11 and can dissipate heat from the heat sink 11. The cooling fan 13 accelerates the heat dissipation and dissipates the heat from the heat sink 11 in time to avoid the heat conduction of the heat sink 11 reaching the maximum value and causing the heat dissipation to be unable to continue.

[0036] Preferably, the transformer module 4 includes a transformer circuit board 21 , a reactance 22 and a capacitor 23 , and the heat dissipation device 10 is disposed on the transformer circuit board 21 .

[0037] Preferably, an upper air outlet 14 and a lower air outlet 15 are respectively provided on the battery pack body 1, wherein the upper air outlet 14 is close to the cooling fan 13, and the lower air outlet 15 is close to the transformer module 4, so as to facilitate heat dissipation from different directions and not limited to one air outlet. The two air outlets are close to various components, which can blow air better and faster.

[0038] Preferably, an arc-shaped plate 16 is provided on the battery pack main body 1, and the lower air outlet 15 is provided on the arc-shaped plate 16. The arc-shaped plate 16 is concave inwardly, close to one side of the transformer module 4, and is placed in an arc direction below the heat dissipation device 10. When the blades of the cooling fan 13 blow air to the heat dissipation device 10, the blown air can directly contact the lower air outlet 15 on the arc-shaped plate 16, so that it can be blown out better and faster, avoiding the downward hot air from still being in contact with the transformer module 4 for a long time and requiring natural wind to blow out.

[0039] Preferably, there are two output ports 5, both of which are provided with dustproof covers. The battery pack body 1 is also provided with a battery socket 17, which is electrically connected to the power output board. The two output ports 5 can charge multiple lithium-ion tools at the same time, and the battery socket 17 can charge the battery. The dustproof cover can effectively prevent dust from entering the battery pack body 1.

[0040] Preferably, the battery pack body 1 is also provided with a main switch 18, a USB output port 12 and a battery charging port 19. A handle 20 is provided on the top of the battery pack body 1, which is convenient for the user to carry the battery pack over a long distance. A shoulder strap can also be provided on the battery pack body 1, so that the battery pack body 1 can be carried on the body, which is convenient for free hands to operate lithium-ion tools. Before operation, the user presses the main switch 18, and then the voltage regulating switch 6 can be pressed. The battery charging port 19 can charge the battery pack 2, and the USB output port can be connected to a USB data cable.

[0041] Preferably, the battery pack body 1 is also provided with a light emitting module, which may be an LED lamp, and the LED lamp may provide lighting outdoors.

[0042] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
