The rotating driving mechanism 412 is used to drive the rotating rod 413 to rotate. The gear 414 is sleeved on the rotating rod 413. The sliding tooth plate 415 is arranged on the lifting fixing block 411 in a lifting and sliding manner. The gear 414 is engaged with the sliding tooth plate 415. The connecting arm 42 is connected to the sliding tooth plate 415. The rotating rod 413 is driven to rotate by the rotating driving mechanism 412, so as to drive the gear 414 to rotate. Since the gear 414 is engaged with the sliding tooth plate 415, the rotation of the gear 414 can drive the sliding tooth plate 415 to move linearly, thereby driving the connecting arm 42 and the electrode sheet 5 to lift.

[0028] More specifically, the rotating driving mechanism 412 comprises a driving motor 412a, a first transmission wheel 412b, a second transmission wheel 412c and a synchronous transmission member 412d.

[0031] Please refer to Figure 1In an embodiment, the electroencephalogram anti-falling detection cap 100 further comprises two magic tapes 7, one end of each of the two magic tapes 7 is connected to the bottom of the auxiliary fixing frame 1, and the other end of each of the two magic tapes 7 is detachably connected together.

[0032] In combination Figures 1 to 4 The specific working principle of the electroencephalogram anti-falling detection cap 100 is as follows:

[0033] When it is necessary to adjust the size of the head circumference space 21 between the two head covers 2, the limiting rod 361 of the moving limiting component 36 of the two anti-falling mechanisms 3 is driven to move, the limiting rod 361 moves away from the clamping position 351 of the limiting chuck 35, and at the same time, the movement of the limiting rod 361 drives the sliding block 362 to slide and press the second elastic element 363, thereby releasing the threaded rod 31, and then the threaded rod 31 is driven to rotate, so as to drive the connecting barrel 32 to move in the direction of approaching or moving away from the head cover 2, thereby pushing or pulling the push rod 33 to move through the first elastic element 34, so that the two head covers 2 move towards each other or away from each other, and the size of the head circumference space 21 between the two head covers 2 is adjusted. When the size of the head circumference space 21 between the two head covers 2 is adjusted, the threaded rod 31 is released, so that the sliding block 362 moves back to the original position under the action of the second elastic element 363, thereby driving the limiting rod 361 to move back to the original position, and the limiting rod 361 is clamped on the other clamping position 351 of the limiting chuck 35, so as to lock the position of the threaded rod 31. Then, the rotating rod 413 is driven to rotate by the rotating driving mechanism 412 of the lifting adjustment module 41, so as to drive the gear 414 to rotate. Since the gear 414 is engaged with the sliding gear plate 415, the rotation of the gear 414 can drive the sliding gear plate 415 to move up and down linearly, thereby driving the connecting arm 42 and the electrode sheet 5 to move up and down. At the same time, the connecting arm 42 can be rotated relative to the sliding gear plate 415, so as to adjust the angle position of the electrode sheet 5, and the electrode sheet 5 can be firmly attached to the head of the patient.

[0034] In summary, the electroencephalogram anti-falling detection cap 100 can adjust the size of the head circumference space 21 between the two head covers 2, so as to adapt to the size of the head circumference of different patients, ensure that different patients can stably wear the electroencephalogram anti-falling detection cap 100, effectively prevent the cap from falling off, improve flexibility, and greatly improve the accuracy of detection. In addition, the electrode sheet 5 of the electroencephalogram anti-falling detection cap 100 can be adjusted in height and angle according to the curvature of the head of the patient, so as to be firmly attached to the head of the patient, and the electroencephalogram anti-falling detection cap 100 has practicality.
