Description

Technical Field

[0001] The utility model relates to the technical field of mobile charging, and particularly relates to a portable outdoor power supply. Background Art

[0002] With the continuous improvement of people's living standards, outdoor camping has gradually become a popular tourism project. However, when people go camping outdoors, they usually need to carry a large number of electronic devices, resulting in a large demand for electricity. For this reason, outdoor mobile power supplies have emerged. These outdoor mobile power supplies can store a large amount of electricity to meet the electricity consumption of the entire camping team.

[0003] However, at present, most of the 2Kw outdoor power supplies on the market weigh about 20kg, which is heavy and difficult to carry. At the same time, when used outdoors, it is inevitable that there will be situations such as dropping and bumping, which also puts forward new requirements for the strength of the outdoor power supply.

[0004] Therefore, a portable outdoor power supply that is convenient to carry and has high strength is needed. Summary of the Utility Model

[0005] The utility model provides a portable outdoor power supply, which can be conveniently carried and the overall strength can be improved.

[0006] In order to solve the above technical problems, the present application provides the following technical solutions:

[0007] A portable outdoor power supply includes a battery pack, a metal frame, a housing, a pull rod, a handle and a mobile wheel set;

[0009] The mobile wheel set is rotatably connected to the rear side of the bottom of the metal frame;

[0010] The number of handles is two, which are respectively fixed on the front side and the rear side of the top of the metal frame;

[0011] The housing wraps the metal frame.

[0012] The principle and beneficial effects of the basic solution are as follows:

[0013] This solution adds a roller set at the bottom of the power supply, which makes it easier for users to carry it. At the same time, the rollers are easy to process and have a strong load-bearing capacity. The rollers also raise the contact height between the outdoor power supply and the ground, which can isolate the ground water to a certain extent when encountering outdoor rainy or humid environments. A retractable pull rod is also added to the bottom, which can be used in conjunction with the roller to better reduce the burden on users. The pull rod can adjust the angle and height to adapt to users of different heights and different usage needs. Adding a pull rod can also increase its stability when dragging, preventing the outdoor power supply from tilting or tipping over due to uneven ground. Setting a handle provides a fulcrum for users, making it convenient for users to move the power supply vertically.

[0014] This solution sets a metal frame, and the battery pack is protected by the metal frame, so that the power supply as a whole has higher strength and can prevent the battery pack from being damaged in harsh outdoor environments.

[0015] Furthermore, the shell includes an upper cover, a lower cover, a left cover, a right cover, a front panel and a rear panel; the upper cover, the lower cover, the left cover, the right cover, the front panel and the rear panel are all fixedly connected to the metal frame.
