Description

Technical Field

[0001] This utility model relates to the field of brain electrical equipment technology, and in particular to a charging case for a brain electrical data acquisition device. Background Technology

[0002] Electroencephalogram (EEG) signals are a synthesis of local neuronal electrical activity recorded from inside or outside the brain's scalp. They contain a wealth of physiological information and can be used to assess a wearer's attention and relaxation levels. They can also be used in the detection and treatment of brain diseases and in the field of intelligent control.

[0003] As shown in the patent document with publication number CN117297614A, the most commonly used EEG signal acquisition device is currently the EEG cap-type acquisition system. In addition to the EEG cap, the EEG cap-type acquisition system is usually equipped with a certain length of electrode wire between the EEG cap and the EEG signal acquisition host. The preparation work before using the EEG cap-type acquisition system is cumbersome and not portable.

[0004] To address the aforementioned issues, as illustrated in the existing patent document CN 115590519 A, portable EEG acquisition devices have emerged on the market. These devices are convenient to carry and use due to their small size, detachable design, and rechargeability. Existing portable EEG acquisition devices generally consist of a main unit, a charging base, and a headband. The main unit can be detached and placed on the charging base for charging, improving battery life. However, while existing portable EEG acquisition devices include a charging base or charging compartment, the structure and function of this base are limited, only allowing for simple charging and placement of the main unit. Furthermore, they typically use a USB interface for connection, requiring users to repeatedly align and unplug the terminals to charge. This results in poor contact between the main unit and the charging base or compartment, leading to unstable charging and making it difficult to meet long-term usage requirements. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a charging case for an EEG acquisition device, which can at least solve one of the problems in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a charging compartment for an EEG collector, which is used in conjunction with the EEG collector.

[0014] In some embodiments, a first magnetic attractor is provided on the positioning post, and a second magnetic attractor is provided on the bottom cover to magnetically engage with the first magnetic attractor.

[0015] In some embodiments, the charging compartment for the EEG collector also includes a cover, one end of which is movably connected to the outer shell and the other end of which can be moved away from or close to the inner shell. When the cover is closed, it can cover the first receiving cavity.
