Description

Technical Field

[0001] This invention relates to the field of transcranial electrical stimulation (TCS) devices, specifically a TCS device with adaptive function. Background Technology

[0002] Transcranial electrical stimulation (tES) is a non-invasive neuromodulation technique that uses low-intensity current (typically 0-2 mA) to stimulate target areas of the cerebral cortex, modulating neuronal excitability, regulating brain wave rhythms, promoting neural remodeling and repair, and improving cerebral blood supply. Since Prior discovered the bidirectional effects of transcranial direct current (tDCS) on the cerebral cortex, tES technology has made significant progress, evolving from a single transcranial direct current to a variety of techniques including transcranial direct current (tDCS), transcranial alternating current (tACS), transcranial pulsed current (tPCS), and transcranial random noise (tRNS). Based on the nature of the stimulation current, tES can be divided into two main categories: transcranial direct current stimulation and transcranial alternating current stimulation. Transcranial electrical stimulation (TES) devices are non-invasive neurostimulation devices that deliver specific, low-intensity currents through the scalp to specific brain regions to alter neuronal activity and regulate mental disorders such as anxiety and depression. This technology is widely used in fields such as cognitive enhancement, mood regulation, pain management, and neurorehabilitation. Traditional transcranial electrical stimulation devices typically use fixed electrode arrangements, which lack the ability to adapt to different user head shapes, sizes, and hair densities. This results in unstable contact between the electrodes and the scalp during wear, making them prone to displacement or detachment, thus affecting the consistency and safety of the stimulation effect. Summary of the Invention

[0003] The purpose of this invention is to provide a transcranial electrical stimulation device with adaptive function to solve the problem of slippage and displacement of the wearing device in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A transcranial electrical stimulation device with adaptive function includes a device body and a wearable device, the wearable device including a fixing component and a moving component; The fixing component includes a connecting mechanism, which is connected to the device body; The moving component includes a first moving mechanism and a second moving mechanism. The first moving mechanism is connected to a connecting mechanism, and the second moving mechanism is connected to the first moving mechanism. The first moving mechanism and the second moving mechanism are used to adjust different wearing sizes. Both the connecting mechanism and the first moving mechanism are equipped with stimulation components, which are connected to the circuit of the device body and are used to apply a weak current.

[0005] The moving component moves the stimulation component, allowing it to conform to and adjust to the head. At the same time, the stimulation component passes through the hair and contacts the scalp. The moving component then further secures the device to the head, preventing it from slipping or shifting. When the moving component is in the retracted state, it wraps around and covers the stimulation component, further protecting it.

[0006] Preferably, the connecting mechanism includes a connector and a fixing plate, wherein the connector is connected to the fixing plate; The first moving mechanism includes a plurality of first connecting groups and a first moving plate, wherein the first connecting groups are respectively connected to a fixed plate and a first moving plate; The second moving mechanism includes several second connecting groups and a second moving plate. The second connecting groups are respectively connected to the first moving plate and the second moving plate. The second moving plate is provided with an adsorption component.

[0007] When it is necessary to wear it, first rotate the second moving plate to the side away from the fixed plate. The second moving plate rotates around the axis of the second connecting group. Then, the second moving plate drives the adsorption component to rotate when it rotates. During the movement, the adsorption component disengages from the first moving plate. Then, the second moving plate rotates to the side of the first moving plate away from the fixed plate. After the second moving plate has moved, several first moving plates and second moving plates form a hemisphere that radiates outward from the fixed plate. The device is then worn on the head, allowing the stimulation components on the fixed plate and the first movable plate to penetrate the hair and contact the scalp. The first movable plate covers the area around the fixed plate and is deflected and adjusted by the first connecting group, so that several first movable plates fit the scalp. The second movable plate is deflected and adjusted by the second connecting group, causing the second movable plate to move the adsorption component, which then adsorbs onto the head, further fixing the device in place. This prevents problems with the electrical stimulation caused by the device shifting during the electrical stimulation process, thus avoiding damage to the head. When the wearable device is retrieved, the second movable plate rotates towards the side closer to the fixed plate. As the second movable plate rotates around the second connecting group, it comes into contact with the first movable plate, thereby bringing the adsorption component into contact with the electrode posts on the first movable plate. This allows the adsorption component to enclose the electrode posts, preventing them from being exposed and thus avoiding damage during storage or transportation. This effectively protects the electrode posts. Meanwhile, the electrode posts on the fixed plate are supported by the first movable plates, which move the second movable plate towards the side closer to the fixed plate. The first and second movable plates form a support structure that encloses the bottom of the fixed plate, further isolating the electrode posts from the outside and protecting them from external elements.

[0008] Preferably, the adsorption assembly includes an adsorption group and a support group, which are respectively disposed on both sides of the second movable plate.

[0009] When the wearable device is unfolded, the adsorption group works in conjunction with the support group to adsorb and hold the head, thereby fixing the wearable device in place. When the adsorption group shrinks during device retraction, it covers and wraps around the electrode post, providing protection. At the same time, the interaction between the support groups generates a certain amount of compressive and frictional force, thereby fixing the first and second moving plates in their retracted state and achieving a limiting effect.

[0010] Preferably, the adsorption group includes a plurality of suction cups, and the plurality of suction cups are disposed on one side of the second movable plate; The support assembly includes at least two support columns, each with a support plate mounted on it, and the support plate is rotatably connected to the support column.

[0011] During the deployment of the device, after the second movable plate detaches from the first movable plate, the suction cup also detaches from the electrode post on the first movable plate. When the second movable plate is in place, the suction cup, like the electrode post on the first movable plate, faces the wearer's head. As the electrode post passes through the hair and contacts the scalp, the suction cup also contacts the scalp, thus achieving adsorption and fixation. While the suction cup is adsorbing, the support plate rotates around the support post, causing the support plate to rotate towards the side closer to the head. This allows the two support plates to clamp and fix the areas on both sides of the second movable plate, further improving the fixation effect of the device. During the retraction of the wearing device, the support plate rotates towards the side closer to the support post, causing the support plate to retract into the second moving plate. At the same time, the suction cup detaches from the scalp. The second moving plate drives the suction cup and the support plate to rotate towards the side closer to the fixed plate, so that the second moving plate comes into contact with the first moving plate during the movement. During the movement, the suction cup covers and wraps the electrode post on the first moving plate. At the same time, because the support plates on the two adjacent second moving plates are in contact with each other, the two support plates squeeze and support each other, thus generating a certain friction between the two support plates. Under the influence of friction, the movement of the first and second moving plates is restricted, thereby keeping the wearing device in a retracted state.

[0012] Preferably, an elastic element is provided between the support column and the second movable plate.

[0013] When the second movable plate detaches from the first movable plate, the support plate will rotate around the support column under the action of the elastic element due to the loss of the support of the adjacent support plate. When the second movable plate is in the contracted state, the two adjacent support plates are squeezed against each other under the action of the elastic element, thereby generating a certain amount of squeezing force and friction between the two support plates, so that the wearable device remains in the contracted state.

[0014] Preferably, the first connecting group includes a first rotating seat, a second rotating seat, and a first rotating column. The first rotating seat is connected to a fixed plate, the second rotating seat is connected to a first movable plate, and the first rotating seat and the second rotating seat are rotatably connected to the first rotating column. The second connecting group includes a third rotating seat, a fourth rotating seat, and a second rotating column. The third rotating seat is connected to the first moving plate, the fourth rotating seat is connected to the second moving plate, and the third and fourth rotating seats are rotatably connected to the second rotating column.

[0015] The first and second rotating seats are deflected and adjusted around the first rotating column, while the third and fourth rotating seats are deflected and adjusted around the second rotating column. This allows the first and second moving plates to adapt to different head shapes of wearers, thereby better adsorbing and fixing the head and further preventing the wearing device from slipping off.

[0016] Preferably, the stimulation component includes a plurality of electrode posts, which are respectively arranged on a fixed plate and a first movable plate, and the electrode posts are electrically connected to the device body through connectors.

[0017] The device itself transmits current to several electrode posts through circuitry, and finally releases it to the head area through the electrode posts, thereby generating electrical stimulation.

[0018] Preferably, the second movable plate is folded toward the side closer to the fixed plate, and when the second movable plate comes into contact with the first movable plate, the electrode post extends into the suction cup.

[0019] Preferably, the first and second moving mechanisms are hemispherical when deployed.

[0020] Preferably, the first and second moving mechanisms form a polyhedron when retracted.

[0021] Compared with the prior art, the beneficial effects of the present invention are: By employing adjustable moving and adsorption components, an adaptive fit to the wearer's head shape is achieved, ensuring stable electrode contact with the scalp and effectively preventing the device from slipping or falling off during stimulation. Specifically, the first and second moving mechanisms can flexibly adjust their angles according to the head contour, allowing the electrodes to pass through the hair and fit tightly against the scalp. The suction cups and support plates in the adsorption components further enhance the device's fixation effect and improve wearing stability. In addition, when the device retracts, the moving components can automatically wrap around and protect the electrode posts, preventing them from being damaged during storage or transportation. This not only improves the device's applicability and safety but also extends the service life of key components. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example: Figures 1-9 As shown, the present invention provides a technical solution: a transcranial electrical stimulation device with adaptive function, including a device body 100 and a wearable device 1, wherein the wearable device 1 includes a fixing component 2 and a moving component 3; The fixing component 2 includes a connecting mechanism 21, which is connected to the device body 100; The moving component 3 includes a first moving mechanism 31 and a second moving mechanism 32.

The first moving mechanism 31 and the second moving mechanism 32 are used to adjust different wearing sizes. Both the connecting mechanism 21 and the first moving mechanism 31 are provided with stimulation components 4. The stimulation components 4 are electrically connected to the device body 100 and are used to apply a weak current.

[0026] In one specific embodiment of the present invention, the first moving mechanism 31 and the second moving mechanism 32 are hemispherical when unfolded.

[0027] In one specific embodiment of the present invention, the first moving mechanism 31 and the second moving mechanism 32 form a polyhedron when retracted.

[0028] In one specific embodiment of the present invention, the connecting mechanism 21 includes a connector 22 and a fixing plate 23, wherein the connector 22 is connected to the fixing plate 23; The first moving mechanism 31 includes a plurality of first connecting groups 33 and a first moving plate 34, wherein the first connecting groups 33 are respectively connected to the fixed plate 23 and the first moving plate 34; The second moving mechanism 32 includes several second connecting groups 35 and second moving plates 36. The second connecting groups 35 are respectively connected to the first moving plate 34 and the second moving plate 36. The second moving plate 36 is provided with an adsorption component 37.

[0029] In a specific embodiment of the present invention, the first connecting group 33 includes a first rotating seat 331, a second rotating seat 332 and a first rotating column 333. The first rotating seat 331 is connected to the fixed plate 23, the second rotating seat 332 is connected to the first moving plate 34, and the first rotating seat 331 and the second rotating seat 332 are rotatably connected to the first rotating column 333. The second connecting group 35 includes a third rotating seat 351, a fourth rotating seat 352, and a second rotating column 353. The third rotating seat 351 is connected to the first moving plate 34, the fourth rotating seat 352 is connected to the second moving plate 36, and the third rotating seat 351 and the fourth rotating seat 352 are rotatably connected to the second rotating column 353.

[0030] In one specific embodiment of the present invention, the adsorption assembly 37 includes an adsorption group 38 and a support group 39, which are respectively disposed on both sides of the second movable plate 36.

[0031] In one specific embodiment of the present invention, the adsorption group 38 includes a plurality of suction cups 381, and the plurality of suction cups 381 are disposed on one side of the second moving plate 36. The support group 39 includes at least two support columns 391, and a support plate 392 is provided on the support column 391. The support plate 392 is rotatably connected to the support column 391.

[0032] In one specific embodiment of the present invention, an elastic element (a torsion spring, one end of which is connected to the support column 391 and the other end of which is connected to the second movable plate 36) is provided between the support column 391 and the second movable plate 36.

[0033] In one specific embodiment of the present invention, the stimulation component 4 includes a plurality of electrode posts 41, which are respectively arranged on the fixed plate 23 and the first movable plate 34. The electrode posts 41 are electrically connected to the device body 100 through the connector 22.

[0034] In one specific embodiment of the present invention, the second movable plate 36 is folded toward the side closer to the fixed plate 23. When the second movable plate 36 and the first movable plate 34 come into contact with each other, the electrode post 41 extends into the suction cup 381.

[0035] Working principle of the invention: When it is necessary to wear it, firstly rotate the second movable plate 36 to the side away from the fixed plate 23. The second movable plate 36 rotates around the axis of the second connecting group 35. Then, when the second movable plate 36 rotates, it drives the adsorption component 37 to rotate. During the movement, the adsorption component 37 disengages from the first movable plate 34. Then, the second movable plate 36 rotates to the side of the first movable plate 34 away from the fixed plate 23. After the second movable plate 36 has moved, several first movable plates 34 and second movable plates 36 form a hemispherical shape radiating outward from the fixed plate 23 as the center. The first rotating seat 331 and the second rotating seat 332 are deflected and adjusted around the first rotating column 333, while the third rotating seat 351 and the fourth rotating seat 352 are deflected and adjusted around the second rotating column 353, so that the first moving plate 34 and the second moving plate 36 can adapt to the head shape of different wearers, thereby better adsorbing and fixing the head, and further preventing the wearing device 1 from slipping off. The device 1 is then worn on the head, so that the stimulation components 4 on the fixed plate 23 and the first movable plate 34 pass through the hair and come into contact with the scalp. The first movable plate 34 covers the area around the fixed plate 23 and is deflected and adjusted by the first connecting group 33, so that several first movable plates 34 are in contact with the scalp. The second movable plate 36 is deflected and adjusted by the second connecting group 35, so that the second movable plate 36 drives the adsorption component 37 to move, and then the adsorption component 37 adsorbs onto the head, further fixing the device 1. This avoids problems with the electrical stimulation caused by the device 1 shifting during the electrical stimulation process, which could lead to damage to the head. During the deployment of the wearing device 1, after the second moving plate 36 detaches from the first moving plate 34, the suction cup 381 also detaches from the electrode post 41 on the first moving plate 34. When the second moving plate 36 is in place, the suction cup 381, like the electrode post 41 on the first moving plate 34, faces the wearer's head. As the electrode post 41 passes through the hair and contacts the scalp, the suction cup 381 also contacts the scalp skin, thus achieving adsorption and fixation. While the suction cup 381 is adsorbing, the support plate 392 rotates around the support post 391, causing the support plate 392 to rotate towards the side closer to the head. This allows the two support plates 392 to clamp and fix the areas on both sides of the second moving plate 36, further improving the fixation effect of the wearing device 1. The device body 100 transmits current to several electrode posts 41 through a circuit, and finally releases it to the head area through the electrode posts 41, thereby forming electrical stimulation. When the wearable device 1 is retrieved, the second moving plate 36 is rotated towards the side closer to the fixed plate 23. During the rotation of the second moving plate 36 around the second connecting group 35, the second moving plate 36 comes into contact with the first moving plate 34. This causes the adsorption component 37 to come into contact with the electrode post 41 on the first moving plate 34, so that the adsorption component 37 wraps the electrode post 41, preventing the electrode post 41 from being exposed and thus avoiding damage to the electrode post 41 during storage or transportation. This achieves the effect of protecting the electrode post 41. As the first moving plates 34 drive the second moving plate 36 to move towards the side closer to the fixed plate 23, the first moving plates 34 and the second moving plate 36 form a support structure and wrap the bottom of the fixed plate 23, thereby isolating the electrode post 41 from the outside and further protecting the electrode post 41 on the fixed plate 23. The support plate 392 rotates towards the side closer to the support post 391, causing the support plate 392 to rotate and retract into the second moving plate 36. At the same time, the suction cup 381 detaches from the head skin. The second moving plate 36 drives the suction cup 381 and the support plate 392 to rotate towards the side closer to the fixed plate 23, so that the second moving plate 36 contacts the first moving plate 34 during the movement. During the movement, the suction cup 381 covers and wraps the electrode post 41 on the first moving plate 34. At the same time, because the support plates 392 on the two adjacent second moving plates 36 are in contact with each other, the two support plates 392 squeeze and support each other, so that a certain frictional force is generated between the two support plates 392. Under the influence of the frictional force, the first moving plate 34 and the second moving plate 36 are restricted from moving, so that the wearing device 1 remains in a retracted state. When the second movable plate 36 disengages from the first movable plate 34, the support plate 392 loses its support from the adjacent support plate 392, causing the support plate 392 to rotate around the support column 391 under the action of the elastic element. When the second movable plate 36 is in the contracted state, the two adjacent support plates 392 are pressed against each other under the action of the elastic element, thereby generating a certain amount of compressive force and friction between the two support plates 392, thus keeping the wearing device 1 in the contracted state.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
