Description

Due to its portability and practicality, outdoor power supply plays an increasingly important role in modern life.

[0003] At present, the basic structure of an outdoor power supply is usually composed of a shell, a power supply body, a battery pack, a control module and an output interface. The power supply body contains the battery pack and the control module, and provides power to external devices through the output interface. The existing outdoor power supply protection structure is mostly in the form of a shell wrapping. The shell is usually made of metal or plastic and has certain impact resistance and protection capabilities. When installed and used, the power supply body is placed inside the shell, and the shell is fixedly connected to the power supply body through fixings to form an overall protection structure, which can protect the outdoor power supply from the external environment to a certain extent.

[0004] However, the existing outdoor power supply protection structure still has some obvious defects. First, the material and structural design of the shell are often too simple to effectively cope with the complex and changeable outdoor environment, such as extreme weather, strong vibration, etc. The existing outdoor power supply is usually set with a large area of ​​heat dissipation holes to ventilate and dissipate heat for the power supply body. However, after the heat dissipation holes are opened, when used in harsh environments, foreign matter such as dust and moisture outside can easily enter through the heat dissipation holes, thereby causing damage and interference to the internal power supply body, affecting the use of the power supply outdoors. In addition, the existing protection structure generally only has simple heat dissipation holes or shutters to naturally dissipate heat for the power supply body. The heat dissipation effect is not good, which can easily lead to rapid loss of the power supply, thereby affecting the use and failing to meet the needs of outdoor activities. Utility Model Content
