[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0019] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for the sake of convenience of description, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0020] Furthermore, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0021] Refer to Figures 1-6, A brain-computer interface connector with an interface fixing and interconnecting device, comprising a first fixing band 1 and a second fixing band 2. A fixing component 3 is arranged between the first fixing band 1 and the second fixing band 2. Connection seats 4 are arranged at one ends of the first fixing band 1 and the second fixing band 2. A fixing ring 5 is arranged on one side of the connection seat 4. A housing 6 is sleeved on the outer side of the fixing ring 5. A rotating block 7 is rotatably arranged on one side of the connection seat 4. A pair of rotating rings 8 are rotatably arranged on the rotating block 7. A double-row connector 61 for processing electroencephalogram signals is arranged inside the housing 6, and the double-row connector 61 is a PIN MALE NANO double-row connector structure with guide post holes. A plurality of sensors are arranged on the inner wall of the rotating ring 8, and the sensors are closely attached to the user's head for collecting electroencephalogram signals.

[0022] Both ends of the fixing ring 5 are connected to the first fixing band 1 and the second fixing band 2 through the connection seat 4. The distance between the fixing ring 5 and the first fixing band 1 and the second fixing band 2 can be adjusted through the connection seat 4, which is convenient for different users to wear the brain-computer interface device. The first fixing band 1 and the second fixing band 2 are quickly connected through the fixing component 3, which is convenient for the user to wear and disassemble the brain-computer interface device. A double-row connector 61 for processing electroencephalogram signals is arranged inside the housing 6. The housing 6 can slide along the fixing ring 5, which is convenient for adjusting the installation position of the housing 6. By rotating the two rotating rings 8 on the rotating block 7, the sensors on the inner wall of the rotating ring 8 are closely attached to the user's head for collecting electroencephalogram signals.

[0023] In the specific implementation process, as Figure 2 , Figure 4 and Figure 5 shown, the fixing component 3 includes a fixing block 31 arranged on one side of the first fixing band 1. A slot 32 is opened on one side of the fixing block 31. An insertion block 33 is fixedly connected to one side of the second fixing band 2. The insertion block 33 is inserted into the inside of the slot 32. A semi-circular rod 34 is rotatably arranged on the inner wall of the fixing block 31. A clamping block 35 is arranged in a fitting manner on one side of the semi-circular rod 34. A clamping groove 36 for cooperating with the clamping block 35 is opened on one side of the insertion block 33. The clamping block 35 is inserted into the clamping groove 36.

[0024] One end of the second fixing band 2 is inserted into the slot 32 inside the fixing block 31 at one end of the first fixing band 1 through the insertion block 33. By rotating the semi-circular rod 34 inside the fixing block 31, the rotation of the semi-circular rod 34 drives the clamping block 35 to move to one side, so that the clamping block 35 is inserted into the clamping groove 36 on one side of the insertion block 33, quickly fixing the insertion block 33, thereby facilitating the quick connection between the first fixing band 1 and the second fixing band 2. When the semi-circular rod 34 is rotated again, the clamping block 35 is separated from the clamping groove 36 on one side of the insertion block 33. At this time, the insertion block 33 can be easily removed from the slot 32, quickly disassembling the first fixing band 1 and the second fixing band 2.

[0025] One side of the connecting seat 4 is inserted with a first connecting rod 9, and one side of the two first connecting rods 9 is fixedly connected to one end of the first fixing belt 1 and the second fixing belt 2 respectively.

[0026] One side of the connecting seat 4 is inserted with a second connecting rod 10, and both ends of the two second connecting rods 10 are fixedly connected to the fixing ring 5.

[0027] The inner walls of the first connecting rod 9 and the second connecting rod 10 are both screwed with a screw rod 11. Moving grooves 12 which are used in cooperation with the screw rod 11 are opened at the top and bottom of the connecting seat 4. One end of the screw rod 11 is fixedly connected with a knob 13.

[0028] By sliding the first connecting rod 9 and the second connecting rod 10 in the connecting seat 4, the distance between the first fixing belt 1 and the second fixing belt 2 and the fixing ring 5 is adjusted. When the first connecting rod 9 and the second connecting rod 10 move, the screw rod 11 slides in the moving groove 12, and the screw rod 11 is rotated by the knob 13 to fix the first connecting rod 9 and the second connecting rod 10.

[0029] A rotating shaft 14 is fixedly connected to the inner wall of the semi-circular rod 34. A turntable 15 is fixedly connected to the top of the rotating shaft 14. A rotating rod 16 is fixedly connected to one side of the turntable 15.

[0030] The turntable 15 is driven to rotate by the rotating rod 16, so that the rotating shaft 14 drives the semi-circular rod 34 to rotate.

[0031] Guide blocks 17 are fixedly connected to the top and bottom of the block 35. The outer sides of the guide blocks 17 are slidably connected to the inner wall of the fixed block 31. When the block 35 moves in the fixed block 31, the guide blocks 17 at the top and bottom of the block 35 slide on the inner wall of the fixed block 31 to guide and limit the block 35, improving the stability of the block 35 when it moves.

[0032] In use, both ends of the fixing ring 5 are connected to the first fixing band 1 and the second fixing band 2 through the connecting seat 4. The distance between the fixing ring 5 and the first fixing band 1 and the second fixing band 2 can be adjusted through the connecting seat 4, which is convenient for different users to wear the brain-computer interface device. One end of the second fixing band 2 is inserted into the slot 32 inside the fixing block 31 at one end of the first fixing band 1 through the insertion block 33. The semi-circular rod 34 rotates inside the fixing block 31, and the rotation of the semi-circular rod 34 drives the clamping block 35 to move to one side, so that the clamping block 35 is inserted into the clamping slot 36 on one side of the insertion block 33 to quickly fix the insertion block 33, thus facilitating the quick connection between the first fixing band 1 and the second fixing band 2. When the semi-circular rod 34 is rotated again, the clamping block 35 is separated from the clamping slot 36 on one side of the insertion block 33. At this time, the insertion block 33 can be easily removed from the slot 32, quickly disassembling the first fixing band 1 and the second fixing band 2, which is convenient for the user to wear and disassemble the brain-computer interface device. Inside the housing 6, there is a double-row connector 61 for processing electroencephalogram signals. The housing 6 can slide along the fixing ring 5, which is convenient for adjusting the installation position of the housing 6. By rotating two rotating rings 8 on the rotating block 7, the sensors on the inner wall of the rotating ring 8 are closely attached to the user's head to collect electroencephalogram signals.
