[0026] A wearable multi-lead EEG collector in an embodiment of the present invention is described in detail below.

[0027] See also Figure 1-Figure 3 As shown, the embodiment of the present utility model proposes a wearable multi-lead EEG collector, including a signal acquisition structure 1 and an amplifier structure 2;

[0030] Specifically, Figure 1The structure of the wearable multi-lead EEG collector is shown schematically.

The wearable multi-lead EEG collector is used on an EEG cap, and the signal acquisition structure 1 is fixed to the signal acquisition end of the EEG cap. The rear cover of the signal acquisition structure 1 is an L-shaped structure formed by a first rear cover and a second rear cover that are perpendicular to each other. The second rear cover is provided with a plurality of holes, and a plurality of wires on the EEG cap can be passed through the plurality of holes and connected to a plurality of female pins 12.

[0031] The signal acquisition structure 1 further includes a front cover plate, which is detachably connected to the rear cover plate. The detachable connection can be a snap connection or a threaded connection, and the detachable connection is not specifically limited here.

[0032] The amplifier structure 2 is mainly composed of a housing and a bottom cover 21. The rear cover of the signal acquisition structure 1 and the bottom cover of the amplifier structure 2 are connected by magnetic attraction.

[0033] The bottom cover 21 of the amplifier structure 2 is provided with a through hole that matches the base 22 of the spring pin male connector, so that multiple spring pin male connectors 23 are exposed through the through hole in the bottom cover 21. The rear cover of the signal acquisition structure 1 is provided with a through hole that matches the female connector 11. The female connector 11 is sealed and fixed to the through hole in the rear cover. Multiple female pins 12 are sealed and fixed to the female connector 11. The multiple female pins 12 pass through the through hole in the rear cover. The multiple female pins 12 are higher than the horizontal plane of the first rear cover. The multiple female pins 12 are brought into contact with the multiple spring pin male connectors 23 through magnetic attraction, and the EEG signals are transmitted to the amplifier through the multiple female pins 12 and the multiple spring pin male connectors 23.

[0034] In this embodiment, the signal acquisition structure 1 further includes a plurality of first magnets, the rear cover is provided with a plurality of first grooves, and the plurality of first magnets are fixedly disposed in the plurality of first grooves.

[0035] For example, the number of the plurality of first magnets of the signal acquisition structure 1 can be five, and the number of the plurality of first grooves provided on the rear cover can be three, with two of the three first grooves being adjacent to each other, and one first groove being spaced apart from two first grooves. Five first magnets can be provided in the three first grooves.

[0036] In this embodiment, the multiple first magnets include multiple first preset magnets and multiple first target magnets. Multiple first preset magnets are fixedly provided on one side of the mother base 11, and multiple first target magnets are provided on the other side of the mother base 11 at preset distances.

[0037] The plurality of first preset magnets are a portion of the plurality of first magnets, and the plurality of first target magnets are another portion of the plurality of first magnets except for the portion of the magnets.

[0038] Exemplarily, two first preset magnets are fixedly provided on one side of the mother base 11, and the two first preset magnets are stacked and arranged in a first groove; on the other side of the mother base 11, three first target magnets are arranged at a preset distance, and two of the three first target magnets are stacked in a first groove, and one of the three first magnets is arranged adjacent to the two first target magnets and arranged in a first groove.

[0039] The rear cover of the signal acquisition structure 1 is equipped with a plurality of first magnets, which can provide sufficient suction force. Meanwhile, the magnets are installed in a fixed order to prevent mistakes during use.

[0040] In this embodiment, a plurality of first openings adapted to the plurality of female needles 12 are opened on the female base 11 , and the plurality of female needles 12 are inserted into the female base 11 through the plurality of first openings.

[0041] Specifically, the plurality of first openings are evenly distributed in the female base 11, and the plurality of first openings are used to install and fix the plurality of female pins 12. The number of the plurality of first openings is the same as the number of the plurality of female pins 12, and one female pin is inserted into one first opening in the female base 11.

[0042] In this embodiment, the rear cover and the female socket 11 are sealed and installed by means of sealant, and the female socket 11 and the plurality of female pins 12 are sealed and installed by means of sealant.

[0043] Specifically, the rear cover is sealed and installed with the female socket 11 by using sealant. The female socket 11 and each female pin are interference fit and sealed with sealant. This ensures that the signal acquisition structure 1 is waterproof and reaches IPX7 waterproof level.

[0044] The front cover and the rear cover of the signal collection structure 1 can be sealed and installed by using sealant.

[0045] In this embodiment, the amplifier structure 2 further includes a plurality of second magnets 24 , and the bottom cover 21 is provided with a plurality of second grooves, and the plurality of second magnets 24 are fixedly disposed in the plurality of second grooves.

[0046] For example, the number of the plurality of second magnets 24 of the amplifier structure 2 can be three, and the number of the plurality of second grooves provided on the bottom cover 21 can be three, with two of the three second grooves being adjacent to each other, and one second groove being spaced apart from two second grooves. Three first magnets can be provided in the three second grooves.

[0047] The bottom cover 21 is provided with a through hole adapted to fit the pogo pin male connector base 22 , and a plurality of pogo pin male connectors 23 can be seen through the through hole of the bottom cover 21 .

[0048] In this embodiment, the number of the plurality of first grooves is the same as the number of the plurality of second grooves.

[0049] The second grooves are positioned at the same position as the first grooves, and are disposed in a one-to-one correspondence with the first grooves. Accordingly, the second magnets 24 are positioned at the same position as the first magnets, and are disposed in a one-to-one correspondence with the first magnets.

[0050] In this embodiment, the plurality of second magnets include a second preset magnet and a plurality of second target magnets. A second preset magnet is fixedly provided on one side of the spring pin male connector base 22, and a plurality of second target magnets are provided on the other side of the spring pin male connector base 22 at preset intervals.

[0051] The plurality of second preset magnets are a portion of the plurality of second magnets 24 , and the plurality of second target magnets are another portion of the plurality of second magnets 24 excluding the portion of the magnets.

[0052] Exemplarily, one side of the spring pin male connector base 22 is fixedly provided with a second preset magnet, and the second preset magnet is arranged in a second groove; on the other side of the spring pin male connector base 22, two second target magnets are arranged at a preset distance, and the two second target magnets are arranged adjacent to each other, and the two second target magnets are respectively arranged in a second groove.

[0053] Figure 2 The bottom cover 21 of the amplifier structure 2 is schematically shown. The bottom cover 21 of the amplifier structure 2 is provided with three second grooves, two of the three second grooves are adjacent to each other, and the two second grooves are spaced apart from the remaining second groove. A second target magnet is respectively provided in the two adjacent second grooves, and the two second target magnets in the corresponding two adjacent second grooves are adjacent to each other. The two adjacent second target magnets are spaced apart by a preset distance and are fixedly provided on one side of the spring pin male connector base 22. A second preset magnet is provided in the remaining second groove, and the second preset magnet is fixedly provided on the other side of the spring pin male connector base 22.

[0054] The bottom cover 21 of the amplifier structure 2 is equipped with a plurality of second magnets 24 , which can cooperate with the plurality of first magnets for magnetic attraction, thereby fixing the amplifier structure 2 .

[0055] A plurality of second magnets 24 are installed inside the bottom cover 21. The magnetic attraction of the magnets can compress the male spring pin so that the male spring pin and the female spring pin come into contact, thereby ensuring the stability of EEG signal transmission during strenuous exercise.

[0056] In this embodiment, a plurality of second openings adapted to the plurality of pogo pin male connectors 23 are formed in the pogo pin male connector base 22 , and the plurality of pogo pin male connectors 23 are inserted into the pogo pin male connector base 22 through the plurality of second openings.

[0057] Specifically, multiple second openings are evenly distributed in the pogo pin male connector base 22. These second openings are used to install and secure multiple pogo pin male connectors 23. The number of these second openings is the same as the number of pogo pin male connectors 23. One pogo pin male connector is inserted into one second opening in the pogo pin male connector base 22. The number of pogo pin male connectors 23 is the same as the number of female pins 12.

[0058] The number of male and female spring pins can be increased or decreased as needed, enabling thousands of leads to be connected.

[0059] In this embodiment, the bottom cover 21 and the pogo pin male connector base 22 are sealed and installed by means of sealant, and the pogo pin male connector base 22 and the plurality of pogo pin male connectors 23 are sealed and installed by means of sealant.

[0060] Specifically, the bottom cover 21 is sealed against the pogo pin male connector base 22 using sealant. The pogo pin male connector base 22 forms an interference fit with each pogo pin male connector, and the sealant seals the pogo pin male connector base against each pogo pin male connector. This ensures that the pogo pin portion of the amplifier structure 2, namely the pogo pin male connector base 22 and each pogo pin male connector, is completely waterproof. The bottom cover of the amplifier structure is also waterproof.

[0061] When EEG signals need to be collected, the signal collection structure 1 and the amplifier structure 2 are attracted to each other via the multiple first magnets and multiple second magnets 24, bringing them into contact. The multiple female pins 12 extending through the through-holes in the rear cover come into contact with the multiple male spring pins 23 visible through the through-holes in the bottom cover 21, allowing the EEG signals collected by the signal collection structure 1 to be transmitted to the amplifier structure 2. During the contact between the multiple female pins 12 and the multiple male spring pins 23, the multiple first magnets and multiple second magnets 24 provide sufficient pressure to ensure sufficient compression between the multiple female pins 12 and the multiple male spring pins 23, ensuring stable EEG signal transmission.

[0062] The signal acquisition structure 1 and the amplifier structure 2 are fixed by magnetic attraction of a plurality of first magnets and a plurality of second magnets 24, and the overall use process is more portable and can be taken out whenever needed.

[0063] Figure 3The schematic diagram shows the contact structure of the male and female spring pins. The female base 11 has multiple evenly distributed first openings, which are compatible with the multiple female pins 12. Each female pin passes through one of the first openings and is inserted into the female base 11. The male spring pin base 22 has multiple evenly distributed second openings, which are compatible with the multiple male spring pins 23. Each male spring pin is inserted into one of the second openings in the male spring pin base 22. When EEG signals need to be collected, the signal collection structure 1 and the amplifier structure 2 are attracted to each other via the multiple first magnets and the multiple second magnets 24, providing sufficient pressure to compress the multiple male spring pins 23, bringing the multiple female pins 12 into contact with the multiple male spring pins 23. The EEG signals collected by the signal collection structure 1 are transmitted to the amplifier structure 2.

[0064] Since the overall volume of the spring pin male and female pins is relatively small and wireless signal transmission can be achieved, the entire wearable multi-lead EEG collector can be made smaller, effectively compressing the volume of the wearable multi-lead EEG collector and reducing the mass of the wearable multi-lead EEG collector. A plurality of first magnets are arranged on the back cover and a plurality of second magnets 24 are arranged on the bottom cover 21, making the use of the wearable multi-lead EEG collector more convenient and quick. The spring pin structure composed of the female seat 11, the plurality of female pins 12, the spring pin male base 22 and the plurality of spring pin males 23 is easier to achieve sealing, meets the overall waterproof and dustproof performance, and is easy to clean. The signal acquisition structure 1, the bottom cover 21 and the spring pin part of the amplifier structure 2 can be effectively sealed and can reach the IPX7 waterproof level.

[0065] The wearable multi-lead EEG collector of an embodiment of the present utility model includes a signal acquisition structure 1 and an amplifier structure 2; the signal acquisition structure 1 includes a rear cover, a female seat 11 and multiple female pins 12, the female seat 11 is sealed and fixed on the rear cover, and multiple female pins 12 are sealed and fixed on the female seat 11, and the multiple female pins 12 are used to receive EEG signals transmitted by multiple wires; the amplifier structure 2 includes a bottom cover 21, a spring pin male head base 22 and multiple spring pin male heads 23, the spring pin male head base 22 is sealed and fixed on the bottom cover 21, and multiple spring pin male heads 23 are sealed and fixed on the spring pin male head base 22. In this way, the female seat 11 is sealed and fixed on the back cover of the signal acquisition structure 1, and multiple female pins 12 are sealed and fixed on the female seat 11. The spring pin male head base 22 is sealed and fixed on the bottom cover 21 of the amplifier structure 2, and multiple spring pin male heads 23 are sealed and fixed on the spring pin male head base 22, so that the female seat 11, multiple female pins 12, spring pin male head base 22 and multiple spring pin male heads 23 can be waterproof, and thus the signal acquisition structure, the bottom cover of the amplifier structure and the spring pin part can be waterproof; the spring pin is smaller in size and can be arranged in space more effectively, so that the EEG cap can arrange more acquisition electrodes, making it easy to achieve multi-lead.
