[0002] With the development of social economy, the demand for mobile energy storage devices has gradually emerged, such as outdoor power consumption problems, equipment backup power problems, and power outage problems. Due to power outages, work cannot continue; due to power outages, equipment, machinery, and tools stop working; due to power outages, people's normal daily life is disturbed; due to geographical restrictions, there is no power in remote areas such as outdoors, which makes it impossible to work and interferes with normal daily life and work. The mobile energy storage device is a multifunctional portable AC / DC emergency treatment large-capacity power bank device. It has a safe power lithium-ion battery and inverter conversion technology, and is a "backup power station" with light weight, high capacity, and high power.

[0003] Existing mobile energy storage devices have good portability and can be moved to a location without a power supply to provide power. However, they have the following defects: (1) Existing mobile energy storage devices install the battery pack for power storage and the control module for controlling the power supply voltage inside the device casing. During inspection and maintenance, the cover on the casing needs to be removed. Existing cover plates are tightened with multiple screw assemblies, which is time-consuming and labor-intensive to remove. As a result, the inspection and maintenance of the mobile energy storage device is inconvenient and time-consuming. To this end, we propose a mobile energy storage device. Utility Model Content

At the same time, after inspection and maintenance, the container box is directly pushed to be sent into the shell again, and the docking column is inserted into the docking groove to be fixed, so that the utility model is convenient and fast for inspection and maintenance, saving time and effort. The designed magnetic block is connected to the docking block by magnetic adsorption. On the end surface of the groove, the fixing effect of the docking column of the container box of the utility model when inserted into the docking groove is improved. The designed baffle is used to limit the pulling and pulling of the container box to prevent it from being pulled out of the pulling cavity due to excessive pulling and affecting the subsequent assembly. The designed spring exerts an elastic extrusion effect on the container box, causing the container box to slide inward, thereby improving the connection firmness of the docking column when inserted into the docking groove. The designed through hole and sliding rod are used to support and correct the spring to prevent the spring from being dislocated from one side of the baffle and losing its elastic extrusion effect.
