Description

Technical Field

[0001] The utility model belongs to the technical field of electroencephalographs, and in particular relates to a wearable electroencephalograph for simulated automobile driving. Background Art

[0002] The wearable EEG device used in car simulation driving is a device that can monitor the driver's brain electrical activity in real time. This device can understand the driver's attention, fatigue level and reaction state by measuring the brain's electrical waves, thereby improving driving safety and driving experience.

[0003] At present, wearable EEG devices capture electrical signals generated by brain activity by placing electrodes on the scalp. The collected electrical signals are amplified and filtered by a display terminal to remove noise and extract effective information. Algorithms are used to analyze brain wave patterns and evaluate the driver's status, such as concentration and nervousness. The analysis results are fed back to the driving simulator or the user so that corresponding adjustments can be made, such as changing driving behavior or taking a rest. The wearable EEG devices for simulated car driving in the prior art have the following disadvantages during use: when the user wears the wearable EEG device, the position of the wearable EEG device is limited only by cables and straps, and it is difficult to accurately locate it on the head. In addition, the wearable EEG device will be in a state of human activity during simulated car driving. Since the user's hair is slippery, once the head shakes, the position of the wearable EEG device will shift, and the electrodes placed on the scalp will easily shift. In order to improve the stability of the wearable EEG device, a wearable EEG device for simulated car driving is needed. Utility Model Content

[0010] As a preferred embodiment, a groove is provided at one end of the plug block near the center of the connecting disk, and a clamping spring is fixed to the inner top wall of the groove. The bottom end of the clamping spring is in a downward arc-shaped structure when the plug block is not inserted into the slot.

[0011] Compared with the prior art, the wearable electroencephalogram for simulated automobile driving provided by the utility model has at least the following beneficial effects:

[0012] In the utility model, when the wearable electroencephalograph for simulated automobile driving is used, the electroencephalograph body can be worn on the head, and the head cover can be covered on the head. In order to ensure the stability of the electroencephalograph body after being worn, the stud can be rotated by a knob, so that the connection plate is moved downward, and a plurality of compression springs respectively drive the rubber ball connected to the bottom airbag to be pressed on the human scalp, thereby effectively ensuring the stability of the electroencephalograph body after being worn.

[0023] Example

[0024] At present, wearable EEG captures electrical signals generated by brain activity by placing electrodes on the scalp.

The wearable EEG for simulated driving in the prior art has the following disadvantages during use: when the user wears it, the position of the wearable EEG is limited only by cables and straps, and it is difficult to accurately locate it on the head. In addition, the wearable EEG is in a state of human activity during simulated driving.
