Description

Technical Field

[0001] This invention belongs to the fields of neural engineering and brain-computer interface technology, specifically relating to a brain-computer interface connection structure that can conform to the curvature of the brain. Background Technology

[0002] Brain-computer interfaces (BCIs) refer to the direct connection created between the brain of a person or animal and an external device, enabling information exchange between the brain and the device. BCI technology is a revolutionary human-computer interaction technology. Its mechanism of action bypasses peripheral nerves and muscles, directly establishing a new communication and control channel between the brain and external devices. By capturing brain signals and converting them into electrical signals, it enables information transmission and control.

[0003] In order to better adapt to the curvature of the head, many existing brain-computer interface devices either fix electrodes on soft plastic parts or use cloth headband devices commonly used in laboratories. However, the electrodes need to be fixed on a hard shell so that they can better contact the skin and collect higher quality EEG data. If the entire device is made of hard materials, it is difficult to match the curvature of the head.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a brain-computer interface connection structure to solve the problem of fitting between the device and the human brain in the prior art.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a brain-computer interface connection structure to solve the problem of fitting between the device and the human brain in the prior art.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] This utility model discloses a brain-computer interface connection structure, including a first shell, a second shell, and a connector. The first shell and the second shell are used to carry the acquisition electrodes. The connector is made of flexible material and is connected and fixed between the first shell and the second shell, so that the first shell and the second shell can form a certain angle.

[0009] In one or more embodiments of this utility model, the connector is detachably connected to the first housing and the second housing.

[0010] In one or more embodiments of this utility model, a fixing hole and a fixing post that can be inserted into the fixing hole are provided between the connector and the first housing and the second housing.

[0011] In one or more embodiments of this utility model, the fixing holes are formed at opposite ends of the connector, and the fixing posts protrude from the first outer shell and the second outer shell.

[0012] In one or more embodiments of this utility model, the two ends of the connector are respectively provided with a plurality of fixing holes, and the first outer shell and the second outer shell are respectively provided with a plurality of fixing posts protruding in an array.

[0013] In one or more embodiments of the present invention, a first notch is formed on the first housing to match the shape of one end edge of the connector, and the fixing post on one side of the first notch surrounds the first notch.

[0014] In one or more embodiments of the present invention, a second notch is formed on the second housing to match the shape of the other edge of the connector, and the fixing post on one side of the second notch surrounds the second notch.

[0015] In one or more embodiments of this utility model, mounting strips protrude from the two ends of the connector, and the fixing holes are formed on the mounting strips.

[0016] In one or more embodiments of this utility model, the connector is further provided with a weight-reducing groove, which is located between the fixing holes at both ends of the connector.

[0017] In one or more embodiments of this utility model, there are two second outer shells, which are respectively disposed on both sides of the first outer shell via the connector.

[0018] Compared with existing technologies, the brain-computer interface connection structure of this invention is relatively simple.

[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0025] like Figure 1-2 As shown, a brain-computer interface connection structure 100 in one embodiment of this utility model includes a first outer shell 10, a second outer shell 20, and a connector 30. The first outer shell 10 and the second outer shell 20 are used to support the acquisition electrodes, and the connector 30 is used to connect the first outer shell 10 and the second outer shell 20. It is made of a flexible material. According to the connection structure 100 in this embodiment, the first outer shell 10 and the second outer shell 20, which are made of rigid materials, can better support and fix the acquisition electrodes, while the connector 30, which is made of flexible material, corresponds to the curvature of the human brain. It can be better integrated and connected with the rigid first outer shell 10 and the second outer shell 20 at both ends, and can be subjected to secondary injection molding. This not only ensures better fixation and installation of the acquisition electrodes, but also allows adjustment of the device curvature to better fit the surface of the human brain, ensuring higher quality of monitored and acquired EEG data.

[0026] Preferably, the connector 30 is made of rubber and is detachably fixed to the first outer shell 10 and the second outer shell 20 on both sides, facilitating the disassembly, maintenance, movement, and transportation of the entire brain-computer interface device. Specifically, the first outer shell 10, the second outer shell 20, and the connector 30 are respectively provided with matching fixing posts and fixing holes, and fixing is achieved by inserting the fixing posts into the fixing holes. For example, in this embodiment, the fixing holes 31 are opened at the edges of opposite ends of the connector 30, and a first fixing post 11 protrudes from the first outer shell 10 at the corresponding fixing position, while a second fixing post 21 is also opened from the second outer shell 20 at the corresponding fixing position. Of course, in other embodiments, they can be interchanged, that is, positioning holes are opened on the first outer shell 10 and the second outer shell 20, and positioning posts protrude from the connector 30. This embodiment is not limited.

[0027] Furthermore, to improve the fixing effect and prevent the first outer shell 10, the second outer shell 20 from abnormally detaching from the connector 30, multiple fixing holes 31 are arrayed at both ends of the connector 30, the same number of first fixing posts 11 protrude from the corresponding fixing position of the first outer shell 10, and the same number of second fixing posts 21 protrude from the corresponding fixing position of the second outer shell 20 as the number of fixing holes 31 on the corresponding side of the connector 30.

[0028] like Figure 2 As shown, a first notch 12 is formed in the first housing 10 at the fixed position corresponding to the connector 30, which matches the edge shape of the connector 30 on that side. Since the fixing holes 31 are arrayed on the edge of the connector 30, the first fixing posts 11 are arranged around the first notch 12 on that side. It is easy to imagine that a second notch 22 is formed in the second housing 20 at the fixed position corresponding to the connector 30, which matches the edge shape of the connector 30 on the corresponding side, and similarly, the second fixing posts 21 are arranged around the second notch 22.

[0029] Preferably, mounting strips 32 protrude from opposite ends of the connector 30, and fixing holes 31 are respectively formed on the corresponding mounting strips 32. The thickness of the mounting strips 32 is less than the thickness of the main body of the connector 30, so the connector 30 will not protrude from the first outer shell 10 and / or the second outer shell 20 after fixing, thus improving the overall integrity.

[0030] like Figure 2 As shown, a weight-reducing groove 33 is also provided on the connector 30, which extends between the fixing holes 31 at both ends. The weight-reducing groove 33 can better realize secondary injection molding, and can also allow the connector 30 to deform better to fit the curvature of the human brain, thereby ensuring that the EEG device collects higher quality EEG signal data.

[0031] In this embodiment, two second outer shells 20 are connected to both sides of the first outer shell 10. Of course, the specific number, shape and position of the outer shells can be set according to the actual situation, and this embodiment is not limited.

[0032] In this embodiment, the acquisition electrode can be directly fixed to a rigid material (first housing 10 and second housing 20). The housings used to fix the acquisition electrode are connected by a connector 30, making the fixed acquisition electrode more secure and stable. The flexible connector 30 is used to bend to accommodate the curvature of the head. Therefore, compared to using all soft materials or cloth strips, both flexibility and stability of the acquisition electrode are ensured, improving the quality of signal data monitoring. At the same time, the first housing 10, the second housing 20, and the connector 30 are connected by fixing holes 31 and interlock with the first fixing post 11 and the second fixing post 21, which facilitates assembly and disassembly and is beneficial to the tensile strength of the plastic after secondary injection molding.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
