[0055] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0056] It should be noted that the "up", "down", "left", "right" and other orientation words described in the embodiments of the present application are described at the angle shown in the drawings, and should not be understood as a limitation of the embodiments of the present application. In addition, in the context, it is also understood that when referring to an element connected to another element "on" or "below", it can be directly connected to another element "on" or "below", or indirectly connected to another element "on" or "below" through an intermediate element.

[0057] Embodiment 1: The present embodiment provides a magnetoencephalography helmet structure, comprising: a device body sliding rail assembly, a front end positioning mechanism and a rear end positioning mechanism, etc. The device body is divided into an upper device body upper half and a lower device body lower half distributed in the upper and lower directions.

[0058] In this example, the lower device body lower half has a lower helmet adapted to the rear half of the human head (the occipital region) on the upper surface of the lower device body lower half and the front end surface.

[0059] In this embodiment, the upper device body upper half has an upper helmet adapted to the front half of the human head (the forehead region) on the lower surface of the upper device body upper half and the front end surface.

[0060] In this example, the upper device body upper half is movably mounted on the lower device body lower half through a sliding rail assembly. The sliding rail assembly has a sliding rail fixed to the upper surface of the lower device body lower half. The sliding rail extends from the front end to the rear end. A sliding block is mounted on the sliding rail and fixedly connected to the lower surface of the upper device body upper half.

[0061] In this embodiment, the front end positioning mechanism can position the upper device body upper half at a first position for forward and backward movement. When the upper device body upper half is positioned at the first position, the upper helmet and the lower helmet correspond in the up and down positions, and can be combined into a complete helmet structure.

[0062] The front end positioning mechanism in the example comprises a knob, a locking base, a locking tongue block, a knob cover, a knob cover plate, a silica gel column and a ceramic ball. The locking base is fixed to the side surface of the upper half of the equipment body and is in the shape of a disc with a notch (3 / 4 of a circle). The locking tongue block is fixed to the lower half of the equipment body and is adapted to the notch of the locking base (1 / 4 of a circle) and can be combined with the locking base to form a complete disc. The knob is provided with a circular mounting groove on the inner end surface thereof, which is adapted to the disc formed by the locking base and the locking tongue block. The knob is provided with a notch channel on the side wall thereof, through which the locking tongue block passes. The knob is mounted on the locking base and can rotate around the center of the disc of the locking base.

[0063] In the example, one end of the silica gel column is fixed to the locking base and the other end is connected to the ceramic ball. The inner end surface of the knob is provided with two notches corresponding to the position of the ceramic ball. When the notch channel of the knob is completely corresponding to the notch position of the locking base, the ceramic ball corresponds to one of the notches on the knob. When the knob is turned by 90° so that the notch channel of the knob is completely misaligned with the notch position of the locking base, the ceramic ball corresponds to the other notch on the knob.

[0064] In the example, an arc-shaped groove is provided on the inner end surface of the knob, and the center of the arc-shaped groove corresponds to the rotation center of the knob. The locking base is connected to a locking screw. One end of the locking screw is fixed to the locking base and the other end extends into the arc-shaped groove on the knob and cooperates with the arc-shaped groove to limit the rotation range of the knob.

[0065] In the example, the center of the knob is provided with a center through hole which is adapted to the circular cover plate and is provided with a step. The knob cover plate has a circular cover plate with a diameter adapted to the diameter of the center through hole. The circular cover plate is fixed to the locking base and is arranged concentrically and coaxially with the locking base. The knob cover has an annular cover plate with an inner diameter smaller than the diameter of the circular cover plate. The annular cover plate is fixed to the knob and is arranged concentrically and coaxially with the knob.

[0066] In the example, the circular cover plate is located in the center through hole of the knob. The inner end side of the circular cover plate is a step of the center through hole, and the outer end side of the circular cover plate is an annular cover plate. The step cooperates with the knob cover to form a clamping groove adapted to the circular cover plate, and the knob can rotate around the circular cover plate.

[0067] The working principle of the front end positioning mechanism in the example is as follows:

[0068] When locking and positioning, the notch channel on the side wall of the knob corresponds to the notch position of the locking base when the knob is rotated. The upper half of the equipment body is moved forward to make the locking base and the locking tongue block relatively close to each other, so that the locking tongue block enters the notch position on the locking base through the notch channel (at this time, the upper half of the equipment body is moved to the first position). Finally, the knob is rotated to misalign the notch channel with the notch position on the locking base.

[0069] When the unlocking is performed, the notch channel on the side wall of the knob corresponds to the notch position on the locking base when the knob is rotated, the rear part of the upper half of the device body moves away to make the locking base and the locking tongue block relatively far away, and the locking tongue block moves out of the knob through the notch channel to realize the separation of the locking base and the locking tongue block.

[0070] In this example, the rear positioning mechanism includes a buckle structure and a locking assembly, wherein the buckle structure has a buckle fixing part, a buckle one and a buckle two, the buckle fixing part is installed on the upper half of the device body, and the buckle one and the buckle two are sequentially installed thereon; the locking assembly has a locking adapter plate and a locking buckle, the locking adapter plate is installed on the lower half of the device body, and the locking buckle is installed thereon.

[0071] In this embodiment, when the upper half of the device body moves to the second position, the buckle two contacts the locking buckle, triggers the locking buckle to enter the locking state, thereby locking the upper half of the device body, and the upper half of the device body can only move backward; when the upper half of the device body moves to the third position which is located behind the second position, the buckle one contacts the locking buckle, triggers the locking buckle to enter the unlocking state, and the upper half of the device body can move forward and backward again.

[0072] In this embodiment, the wiring assembly is arranged in the upper half of the device body, which includes a wiring support frame, an upper layer soft cable fixing plate, an upper layer cable fixing frame, an optical fiber fixing plate, a lower layer cable fixing frame, a lower layer soft cable fixing plate, a bottom layer soft cable fixing plate, a bottom layer cable fixing plate and the like.

[0073] In this example, the wiring support frame is connected to the helmet fixing frame of the upper half of the device body, the upper layer cable fixing frame is connected to the helmet fixing frame, the optical fiber fixing plate and the upper layer soft cable fixing plate are connected to the upper layer cable fixing frame, the lower layer cable fixing frame is connected to the helmet fixing frame, and the lower layer soft cable fixing plate is connected to the lower layer cable fixing frame; the bottom layer soft cable fixing plate and the bottom layer cable fixing plate are connected to the base of the upper half of the device body.

[0074] In this embodiment, the sensor soft cable is connected to the probe and the PCB through the bottom layer soft cable fixing plate, the lower layer soft cable fixing plate and the upper layer soft cable fixing plate, and the optical fiber is connected to the external laser through the optical fiber fixing plate and the bottom layer cable fixing plate. Through various cable fixing assemblies, the cable inside the helmet can not be shaken randomly with the movement of the upper helmet.

[0075] In this embodiment, the sound guide assembly is arranged at the front end position of the lower half of the device body to provide sound guidance for the patient.
