[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-2 As shown, a portable brain-computer interface device includes a main body 1. A support component 2 is fixedly installed on the lower surface of the main body 1 for easy carrying of the device.

A power supply module for providing necessary power support to the system is installed inside the signal processing module 5. Graphene electrodes 7 for capturing brain activity signals are installed on the lower surfaces of both the signal acquisition module 6 and the signal processing module 5.

[0030] The support assembly 2 includes two support rings 21. The upper surface of the upper support ring 21 is fixedly installed to the lower surface of the main body 1. The support ring 21 includes a shell 211 that disperses impact energy and protects the head. An outer layer 212 that provides good breathability and durability while reducing the feeling of stuffiness in the head is fixedly installed on the inner side of the shell 211. The shell 211 is made of a composite material with impact resistance and high strength, and the outer layer 212 is made of polyester fiber.

[0031] The support component 2 consists of two support rings 21, which can minimize the weight of the device to improve comfort and facilitate carrying when going out. The outer shell 211 has the characteristics of high strength, low density, corrosion resistance, heat resistance, wear resistance and durability, which can disperse impact energy and protect the user's head, improving the safety of use. Furthermore, the outer layer 212 can provide good breathability and durability for the support component 2 while reducing the feeling of stuffiness on the head, which can effectively improve the wearing comfort and safety of the support ring 21.

[0032] The fixing strap 3 is made of cotton fiber to provide a soft touch and good moisture absorption. It is fixedly installed on the right side of the lower surface of the lower support ring 21 and the right end of the fixing strap 3. A vertical plate 10 is fixedly installed on the left side of the lower surface of the lower support ring 21. A straight groove plate 12 is fixedly installed on the left side of the vertical plate 10. A pressure plate 9 is rotatably connected to the left end of the straight groove plate 12. When the pressure plate 9 is in a vertical state, it forms a cross shape with the straight groove plate 12 to press and limit the fixing strap 3. Several straight grooves 11 are opened through the left side of the fixing strap 3. The inner cavity of the straight groove 11 matches the outer side of the straight groove plate 12.

[0033] In use, the support component 2 is placed on the user's head, so that the main body 1 and the signal processing module 5 fit the user's head so that the graphene electrode 7 can collect signals of brain activity. The fixing strap 3 is placed on the user's jaw. When the tightness needs to be adjusted, the pressure plate 9 is rotated from a vertical position to a horizontal position to release the restriction on the fixing strap 3. The straight grooves 11 on the fixing strap 3 are moved according to the usage requirements. One straight groove 11 represents a fixed distance. After moving to the appropriate position, the straight groove 11 is inserted into the outside of the straight groove plate 12 so that the pressure plate 9 is exposed on the outside of the fixing strap 3. The pressure plate 9 is rotated from a horizontal position to a vertical position to press and fix the fixing strap 3, thereby adjusting the tightness of the wearing to provide a good wearing experience.

[0034] like Figure 2 , Figure 5 As shown, cylindrical connecting columns 22 are fixedly installed between the opposite sides of the two support rings 21 and are arranged in a ring array. The outer side of the support rings 21 is provided with through holes 23 to reduce weight. There are six through holes 23 arranged in a ring array.

[0035] By connecting the two support rings 21 into one unit through the connecting column 22 and cooperating with multiple through holes 23, the weight of the device can be effectively reduced to improve comfort and facilitate carrying when going out.

[0036] like Figure 6 As shown, an inner liner 213 is fixedly installed on the inner side of the outer layer 212 to absorb and disperse impact energy and reduce direct impact on the head. The material of the inner liner 213 is polyurethane foam.

[0037] Liner 213 has excellent cushioning properties, effectively reducing the transmission of impact force and direct impact on the head, while providing good comfort and support.

[0038] like Figure 6 As shown, a nonwoven lining 214 that provides a good fit and breathability is fixedly installed on the inside of the lining 213.

[0039] Nonwoven lining 214 is a lightweight, soft, and breathable material that effectively reduces stuffiness around the head.

[0040] like Figure 6 As shown, memory foam 215 for enhancing comfort is fixedly installed on the inside of the nonwoven lining 214.

[0041] Memory foam 215 is a slow-rebound material that can adjust its firmness according to the user's body temperature and pressure changes, thereby reducing discomfort caused by prolonged wear and providing a good fit and support, reducing pressure and friction on the skin.

[0042] like Figures 1-2As shown, a hanging plate 4 with a storage fixing strap 3 is fixedly installed on the rear side of the support component 2.

[0043] The hanging plate 4 is used to hang the fixing strap 3, making it easy to carry.

[0044] The working principle of this utility model is as follows: During use, the support component 2 is placed on the user's head, ensuring the main body 1 and signal processing module 5 are in close contact with the user's head so that the graphene electrode 7 can collect signals of brain activity. The fixing strap 3 is then placed around the user's jaw. To adjust the tightness, the pressure plate 9 is rotated from a vertical to a horizontal position, releasing the restriction on the fixing strap 3. The straight grooves 11 on the fixing strap 3 are moved according to usage requirements; one straight groove 11 represents a fixed distance. After moving to the appropriate position, the straight grooves 11 are inserted into the outside of the straight groove plate 12, exposing the pressure plate 9 on the outside of the fixing strap 3. The pressure plate 9 is then rotated from a horizontal to a vertical position, tightening and fixing the fixing strap 3, thereby adjusting the tightness of the fit. To provide a good wearing experience, when it is necessary to carry it, the fixing strap 3 is hung on the hanging plate 4, and the support component 2 is composed of two support rings 21 and through holes 23, which can minimize the weight of the device to improve comfort and facilitate carrying when going out. Through the composite use of shell 211, outer layer 212, inner lining 213, non-woven lining 214 and memory foam 215, the wearing comfort and safety of support ring 21 can be effectively improved. Memory foam 215 has the characteristics of strong shock absorption, good temperature response and good breathability. It can adjust the hardness according to the user's body temperature and pressure changes to provide a good fit and support, reduce pressure and friction on the skin, and thus reduce the discomfort caused by prolonged wear.
