Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation equipment, and in particular to a brain-computer device and a rehabilitation apparatus. Background Art

[0002] Existing brain-computer interface (BCI) technologies are mainly divided into two categories: invasive and non-invasive. Invasive BCI requires electrodes to be implanted in the user's brain, which has high requirements for the user and the operating environment and is not conducive to widespread promotion. In contrast, non-invasive BCI uses non-invasive EEG signal monitoring technology and has wider application potential.

[0003] The rehabilitation exoskeleton robot is an exoskeleton device that helps patients with limb disabilities to conduct rehabilitation training. It is an effective rehabilitation method that uses the principle of motor imagery to collect the patient's motor imagery intention through the brain-computer interface device and drives the exoskeleton robot to assist the patient in limb activity training. This technology combines the advantages of brain-computer interface and exoskeleton devices, providing patients with a new means of rehabilitation.

[0004] However, existing non-invasive brain-computer interface devices still have some inconveniences in use. The traditional bandage-type electrode cap cannot adapt well to the head shapes of different people, so that the contact surface between the electrode cap and the user's scalp cannot be effectively guaranteed during use, and the collected signal is unstable. At the same time, the collection of EEG signals has high requirements for the environment. Noisy sounds and visual interference will affect the accuracy of the signal. When used in combination with an exoskeleton robot, the brain-computer device requires the patient to concentrate on motor imagination, which places high demands on the patient's concentration.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0046] The first aspect of the present invention provides a brain-computer device, such as Figure 1 and Figure 2 As shown, it includes a binding component 1, an auditory immersion component 2, an adjustment belt 3 and a collection component 4;

[0047] The binding component 1 is used to fix the brain-computer device to the user's head;

[0048] The auditory immersion component 2 is connected to the binding component 1, and the auditory immersion component 2 is used to be buckled on the ear of the user;

[0049] The adjustment belt 3 is connected to the auditory immersion component 2. The adjustment belt 3 is used to be worn on the top of the user's head. The length of the adjustment belt 3 and the angle relative to the auditory immersion component 2 are adjustable.

[0050] The collection component 4 is connected to the adjustment belt 3, and the collection component 4 is used to collect the user's brain electrical signals.

[0051] Reference Figure 1 and Figure 2 As shown, when in use, the binding component 1 is bound to the user's head to fix the brain-computer device. On this basis, the length of the adjustment belt 3 can be adjusted. For users with larger heads, the length of the adjustment belt 3 can be extended so that the auditory immersion components 2 on both sides of the adjustment belt 3 can be accurately buckled on the user's ears, reducing the interference of external noise and facilitating the patient to concentrate on motor imagery; on the contrary, for users with smaller heads, the length of the adjustment belt 3 can be shortened. Figure 2 As shown, the user can also adjust the angle of the adjustment belt 3 relative to the auditory immersion component 2. By rotating the adjustment belt 3 forward, the collection component 4 on the adjustment belt 3 will be closer to the user's forehead. By rotating the adjustment belt 3 backward, the collection component 4 on the adjustment belt 3 will be closer to the back of the user's head. The user can adjust the adjustment belt 3 to a suitable position according to habit, so that the collection component can fit the scalp better and ensure the stability of the collected signal.

[0052] The auditory immersion component 2 is described in detail below:

[0053] In an optional embodiment, if Figure 3 and Figure 4 As shown, the auditory immersion component 2 includes an earmuff 21, a knob 22 and a first brake member 23, wherein:

[0054] The earmuff 21 is fixedly mounted on the binding assembly 1, the end of the adjustment belt 3 extends into the earmuff 21 and rotates with the earmuff 21, and the knob 22 is movably matched with the earmuff 21;

[0055] The first brake member 23 is located in the earmuff 21 and slides with the earmuff 21 in a direction gradually approaching or moving away from the adjusting belt 3 . When the first brake member 23 contacts the end of the adjusting belt 3 , the first brake member 23 is engaged with the adjusting belt 3 .

[0056] Combination Figure 4 The use process of the above-mentioned auditory immersion component 2 is specifically described:

[0057] When the angle of the adjusting belt 3 needs to be adjusted, the gap between the first brake member 23 and the adjusting belt 3 is increased by turning the knob 22, and the engagement between the first brake member 23 and the adjusting belt 3 is cancelled. At this time, the adjusting belt 3 can be rotated. After the adjusting belt 3 is rotated to a suitable angle, the gap between the first brake member 23 and the adjusting belt 3 is reduced by turning the knob 22, so that the first brake member 23 and the adjusting belt 3 are engaged. Since the first brake member 23 slides with the earmuff 21 in a direction gradually approaching or moving away from the adjusting belt 3, the first brake member 23 will limit the rotation of the adjusting belt 3, ensuring that the adjusting belt 3 is fixed at the above-mentioned angle.

[0058] The auditory immersion component 2 has a simple structure, and the user can adjust the angle of the adjustment belt 3 by turning the knob 22, which is convenient for the user to operate.

[0059] Specifically, the knob 22 can be threadedly matched with the earmuff 21. When the knob 22 is rotated relative to the earmuff 21, the end of the knob 22 extending into the earmuff 21 can be Figure 4 As shown, the first brake member 23 is pushed to the right or retracted to the left.

[0060] There are many ways to engage the first brake member 23 with the adjusting belt 3. For example, a protrusion is provided on one side of the first brake member 23 facing the end of the adjusting belt 3, and the adjusting belt 3 has a groove. When the protrusion extends into the groove, the first brake member 23 engages with the adjusting belt 3.

[0061] In an optional embodiment, if Figure 4As shown, the first brake member 23 has a first tooth surface 231 on the side facing the end of the adjusting belt 3, and the end of the adjusting belt 3 has a second tooth surface 321 for engaging with the first tooth surface 231. When the first brake member 23 abuts against the adjusting belt 3 under the action of the knob 22, the first tooth surface 231 meshes with the second tooth surface 321, and the first brake member 23 restricts the rotation of the adjusting belt 3; when the knob 22 is withdrawn to the left, the first brake member 23 cancels the pressing of the adjusting belt 3, and the second tooth surface 321 can rotate forward and backward relative to the first tooth surface 231.

[0062] Specifically, two earmuffs 21 are provided, one earmuff 21 is connected to one end of the adjustment belt 3, and the other earmuff 21 is connected to the other end of the adjustment belt 3, and they are buckled on the left and right ears of the user respectively.

[0063] In an optional embodiment, if Figure 5 As shown, the earmuff 21 may include a first cover body 211 and a second cover shell 212. The first cover body 211 and the second cover shell 212 are buckled with each other, and the fixing method of the two may be snap connection, bonding or screw connection.

[0064] like Figure 4 and Figure 5 As shown, a fixed shaft 216 is connected to the first cover body 211, the first brake member 23 slides with the fixed shaft 216 along the axial direction of the fixed shaft 216, the end of the adjusting belt 3 rotates with the fixed shaft 216, the knob 22 can be threadedly engaged with the second cover shell 212, and when the knob 22 rotates, the end of the knob 22 extending into the earmuff 21 can push the first brake member 23 to slide relative to the fixed shaft 216, so that the first tooth surface 231 on the first brake member 23 engages with the second tooth surface 321 on the adjusting belt.

[0065] Specifically, a sliding groove extending in a direction parallel to the axial direction of the fixed shaft 216 may be provided on the fixed shaft 216 , and a protrusion 232 slidably matched with the sliding groove may be provided on the first braking member 23 .

[0066] In addition, if Figure 5 As shown, the first cover body 211 is the side of the earmuff 21 close to the user's face. The first cover body 211 is provided with an ear electrode cloth 24, and the ear electrode cloth 24 is silver-plated to collect electrode signals at the position of the user's ear.

[0067] In an optional embodiment, if Figure 5 As shown, the first cover body 211 and the second cover shell 212 are internally equipped with structures such as a battery 213, a speaker 214 and a control board 215. The battery 213 provides power for the speaker 214 and the control board 215. The speaker 214 can transmit the sound of the device to the human ear for voice guidance or playing light music.

[0068] In an optional embodiment, if Figure 5 As shown, one of the two earmuffs 21 has a switch button 217, which is mounted on the second housing 212 and electrically connected to the control board 215. The switch button 217 can be pressed to turn the device on and off.

[0069] In order to make the user more comfortable, a sponge is provided on the side of the first cover body 211 facing the face, so that the face is more comfortable when it fits against the first cover body 211, and the earmuff 21 also has a better sound-collecting effect.

[0070] The structure of the adjustment belt 3 is described in detail below:

[0071] In an optional embodiment, if Figure 5 and Figure 6 As shown, the adjustment belt 3 includes a first telescopic belt 31 and a second telescopic belt 32 arranged at both ends of the first telescopic belt 31. One end of the second telescopic belt 32 extends into the knob 22 and rotates with the fixed shaft 216, and the other end slides with the end of the first telescopic belt 31 along the extension direction of the first telescopic belt 31 and is provided with a limiting structure 33.

[0072] When in use, the first telescopic band 31 can be pulled out from the second telescopic band 32 to lengthen the length of the adjustment band 3, or the distance extended into the second telescopic band 32 can be increased to shorten the length of the adjustment band 3. After the adjustment is completed, the limiting structure 33 limits the distance that the first telescopic band 31 extends relative to the second telescopic band 32.

[0073] The above-mentioned adjustment belt 3 is segmented to facilitate length adjustment. In a preferred embodiment, the second telescopic belt 32 is configured as two, one second telescopic belt 32 slides with one end of the first telescopic belt 31, and the other second telescopic belt 32 slides with the other end of the first telescopic belt 31, thereby realizing two-way adjustment of the two ends of the first telescopic belt 31.

[0074] It should be noted that there are many optional structures of the limiting structure 33. For example, the limiting structure 33 includes a plurality of slots provided on the first telescopic band 31 and a buckle provided on the second telescopic band 32. The plurality of slots are spaced apart along the extension direction of the first telescopic band 31, and the buckle can be snapped into any one of the slots.

[0077] The elastic component 333 and the second brake member 332 are both disposed in the second telescopic band 32 and are slidably matched with the button 331 in a direction gradually approaching or moving away from the end of the first telescopic band 31;

[0078] The pry bar 334 is rotatably installed in the second telescopic belt 32 , one end of the pry bar 334 abuts against the button 331 , and the other end of the pry bar 334 abuts against the elastic component 333 .

[0079] When in use, the elastic component 333 presses the second brake member 332 against the end of the first telescopic band 31 under the action of its own elastic force, and the second brake member 332 locks the position of the first telescopic band 31 relative to the second telescopic band 32; when it is necessary to adjust the extension distance of the first telescopic band 31 relative to the second telescopic band 32, the button 331 is pressed, and the pry bar 334 squeezes the elastic component 333 under the pressure of the button 331, and the elastic component 333 cancels the pressing of the second brake member 332 against the end of the first telescopic band 31, and the extension distance of the first telescopic band 31 relative to the second telescopic band 32 is adjustable. After the adjustment is completed, the button 331 is reset under the action of the reset member 335, and the position of the first telescopic band 31 relative to the second telescopic band 32 is locked.

[0080] When the limiting structure 33 is used, the user only needs to press the button 331 downward. The button 331 can be reset when no force is applied, which is convenient for the user to operate.

[0081] The reset member 335 may be, but is not limited to, a coil spring.

[0082] In an optional embodiment, if Figure 6 As shown, a guide column 3311 is provided on the button 331, and the elastic component 333 includes a spring 3331 and a limit plate 3332 both slidably mounted on the guide column 3311, one end of the spring 3331 abuts against the button 331, and the other end abuts against the limit plate 3332.

[0083] The second brake member 332 is located on the side of the limiting plate 3332 away from the spring 3331, and the second brake member 332 is slidably sleeved on the end of the guide column 3311. When in use, the elastic force of the spring 3331 itself is transmitted to the second brake member 332 through the limiting plate 3332, so that the second brake member 332 squeezes the end of the first telescopic band 31; the side of the limiting plate 3332 away from the spring 3331 also abuts against the pry bar 334, when the button 331 is pressed, the pressing of the pry bar 334 at the button 331 squeezes the spring 3331 through the limiting plate 3332, at this time, the second brake member 332 cancels the pressing of the first telescopic band 31, and the first telescopic band 31 can be freely extended.

[0084] Among them, Figure 6As shown, a support member 322 is fixed inside the second telescopic band 32, and the middle part of the pry bar 334 is rotatably connected to the support member 322, the first extending end of the pry bar 334 abuts against the pressing rod extending from the middle part of the button 331, and the second extending end of the pry bar 334 abuts against the side of the limit plate 3332 away from the spring 3331.

The plurality of electrode heads 43 are used to contact the user's scalp.

[0092] Specifically, the electrode head 43 includes an electrode cluster 431, and the electrode cluster 431 includes dozens of flexible support rods 4311. The bottom of the flexible support rods 4311 that contacts the user's head has an electrode protrusion 4312, and the electrode protrusion 4312 is an elliptical surface to avoid the user feeling uncomfortable when the scalp is pressed tightly.

[0093] Among them, the flexible support rod 4311 can include an inner layer and an outer layer. The inner layer is made of conductive material, and the conductive material is in contact with the electrode protrusion 4312. The outer layer is made of polypropylene material with good flexibility. With good toughness support, the electrode protrusion 4312 can pass through human hair smoothly.
