Description

Technical Field

[0001] This utility model relates to information collection and analysis equipment, and more particularly to an EEG-fNIRS data collection and analysis equipment. Background Technology

[0002] EEG-fNIRS (electroencephalography-functional near-infrared spectroscopy) is a neuroimaging technique that combines electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS). This technique can simultaneously measure changes in the brain's electrical activity and hemodynamics, making it an important tool in neuroscience research, clinical diagnosis, and brain function monitoring. EEG-fNIRS combines the high temporal resolution of EEG with the spatial resolution of fNIRS, providing multidimensional information about the brain's functional state and finding wide application in various fields such as brain science, neuroscience, and cognitive function research.

[0003] Currently, common signal acquisition devices in EEG-fNIRS systems include a signal acquisition cap, an analysis device, wiring harnesses, and an adjustment device. For example, the existing Chinese utility model patent CN219331639U discloses a signal acquisition cap that integrates multiple EEG electrodes and an fNIRS probe for acquiring brain signals. Furthermore, the device includes multiple EEG and fNIRS connection cables, through which signals are transmitted to the analysis device. The adjustment device in this patent uses an adjustment rod rotatably mounted on the analysis device, with multiple elastic unidirectional claw units arranged sequentially on the adjustment rod for supporting and adjusting the positions of the first and second adjustment sleeves.

[0004] While the aforementioned signal acquisition cap design improves temporal and spatial resolution and facilitates device adjustment, it still presents some practical inconveniences. Particularly when moving the second adjustment sleeve, the process is cumbersome. Users must first remove the pin, then adjust it to the designated position, and finally reinsert it. Because the pin is located at the top of the overall structure, operation is not straightforward, especially for shorter users. Therefore, it is necessary to provide a new data collection and analysis device to address these issues. Utility Model Content

The side of the first adjusting member away from the guide sleeve includes a first plane, a first inclined plane, and a second plane. The first plane is parallel to the second plane, and the first plane abuts against the side of the first positioning member facing the guide sleeve. The second plane protrudes from the first plane on the side away from the guide sleeve. The first plane is smoothly connected to the second plane through the first inclined plane.

[0027] The distance between the second plane and the first plane is configured such that when the first positioning member abuts against the second plane on the side facing the guide sleeve, the first locking block separates from the first positioning groove.

[0053] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0054] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this application. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0055] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0056] like Figure 1 and Figure 4 As shown, a preferred embodiment of this application provides a collection and analysis device, including a main body 1, a first guide assembly, a second guide assembly, a first limiting sleeve 19, and a second limiting sleeve 13. The main body 1 includes a mounting plane. The first guide assembly includes a first guide shaft 2 and a guide sleeve 18. One end of the first guide shaft 2 is connected to the mounting plane, and the axis of the first guide shaft 2 is perpendicular to the mounting plane. The guide sleeve 18 is movably sleeved outside the first guide shaft 2 and moves controllably along the axial direction of the first guide shaft 2. The second guide assembly includes a second guide shaft 3 and a sliding sleeve assembly. The second guide shaft 3 is fixedly installed at the end of the first guide shaft 2 away from the mounting plane, and the axis of the second guide shaft 3 is perpendicular to the axis of the first guide shaft 2. The sliding sleeve assembly is movably sleeved outside the second guide shaft 3 and moves controllably along the axial direction of the second guide shaft 3. The first limiting sleeve 19 is connected to the guide sleeve 18, and the second limiting sleeve 13 is connected to the sliding sleeve assembly.

[0057] Specifically, the main body 1 is an EEG-fNIRS collection and analysis device. This device is a neuroimaging system that combines electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) technologies to simultaneously measure and analyze changes in brain electrical activity and hemodynamics. This device is widely used in neuroscience research, brain function monitoring, cognitive research, and clinical diagnosis, providing researchers and physicians with multi-dimensional information on brain function. The main body 1 includes a mounting plane that is horizontal during device use. The cross-sectional shape of the first guide shaft 2 can be circular, rectangular, or irregularly shaped; for example, a rectangle... Figure 1 As shown, the first guide shaft 2 is a quadrangular prism, and the guide sleeve 18 is a hollow quadrangular short prism to match it. The shape and size of the cross-sectional profile of its hollow part are adapted to the shape and size of the cross-sectional profile of the first guide shaft 2. The shape and structure of the second guide shaft 3 can be similar to that of the first guide shaft 2. The functions of the first limiting sleeve 19 and the second limiting sleeve 13 are the same as those of the first adjusting sleeve and the second adjusting sleeve disclosed in CN219331639U.

[0058] This implementation, through the cooperation of the guide sleeve 18 and the sliding sleeve assembly with the first guide assembly and the second guide assembly respectively, achieves the function of controlling the first limiting sleeve 19 and the second limiting sleeve 13 to move axially along the first guide shaft 2 and the second guide shaft 3 respectively. This avoids the cumbersome steps of removing the pin in the traditional technology, effectively solving the problem of inconvenient adjustment operation in the prior art. Especially for users with shorter stature, the new design improves the convenience of equipment adjustment, thereby realizing simpler and faster adjustment operation, improving user experience, and improving the efficiency and comfort of equipment use.

[0059] In some embodiments, a limiting disc 4 for limiting the range of motion of the sliding sleeve assembly is fixedly connected to one end of the second guide shaft 3 away from the first guide shaft 2.

[0060] In some embodiments, to allow the first limiting sleeve 19 to move in a controlled manner, such as Figures 4 to 7As shown, a plurality of first positioning grooves 17 are provided on one side of the first guide shaft 2, and the extension direction of each first positioning groove 17 is perpendicular to the axial direction of the first guide shaft 2. Furthermore, a first through groove 20 is provided on one side of the guide sleeve 18, and the first through groove 20 and the first positioning grooves 17 are located on the same side. The collection and analysis device also includes a first positioning component, which includes a first locking block 21. The first locking block 21 is movably connected to the guide sleeve 18, and the first locking block 21 is aligned with the first through groove 20. The first locking block 21 is configured such that when the first through groove 20 is aligned with a first positioning groove 17, the first locking block 21 moves towards the first guide shaft 2 to allow the first locking block 21 to pass through the first through groove 20 and engage with the first positioning groove 17; or when the first locking block 21 moves away from the first guide shaft 2, the first locking block 21 separates from the first positioning groove 17.

[0061] In this embodiment, the collection and analysis device employs a cooperative structure between the first limiting sleeve 19 and the first positioning groove 17, the first through groove 20, and the first locking block 21 on the first guide shaft 2. This allows the first limiting sleeve 19 to move precisely. Furthermore, the controlled positioning and flexible adjustment of the first limiting sleeve 19 are achieved through the engagement and disengagement of the first locking block 21 with the first positioning groove 17. This effectively solves the problems of insecure engagement and cumbersome operation of the first limiting sleeve 19 during adjustment and positioning in the prior art, thereby achieving stable positioning and convenient adjustment of the first limiting sleeve 19 and improving the accuracy and convenience of device operation.

[0062] Furthermore, in some embodiments, in order to achieve automatic locking of the position of the first limiting sleeve 19, such as... Figures 5 to 6 As shown, the first positioning assembly also includes a first positioning element 22 and a first elastic element 24. The first positioning element 22 is connected to the side of the first locking block 21 opposite to the first guide shaft 2, so that the first locking block 21 moves with the first positioning element 22.

[0063] The first positioning member 22 is connected to the guide sleeve 18 through the first elastic member 24. The first elastic member 24 applies a spring force to the first positioning member 22 pointing towards the guide sleeve 18, so that the first positioning member 22 has a tendency to move towards the guide sleeve 18.

[0064] In this embodiment, the collection and analysis device employs a cooperative structure of the first positioning element 22, the first locking block 21, and the first elastic element 24. This allows the first locking block 21 to automatically engage with and stably lock into the first positioning groove 17 during movement. Furthermore, the elastic force applied by the first elastic element 24 ensures that the first positioning element 22 moves towards the guide sleeve 18, thereby achieving automatic locking of the first limiting sleeve 19. This effectively solves the problems of unstable positioning and difficult manual operation in the prior art, thereby achieving automatic position locking and precise adjustment, and improving the automation level and ease of operation of the device.

[0065] Among them, guide rods 23 that restrict the movement trajectory of the first positioning member 22 are fixedly connected to the opposite sides of the guide sleeve 18. The first positioning member 22 has a guide groove that matches the guide rod 23. The guide rod 23 is inserted into the guide groove, and there are multiple guide grooves. The number of guide rods 23 is the same as the number of guide grooves, and the two are matched in position. The first elastic element 24 is sleeved on the outside of the guide rod 23. The number of the first elastic elements 24 is adapted to the number of guide rods 23. When the first elastic element 24 is a spring, the two ends of the first elastic element 24 abut against the limiting structure on the side of the guide rod 23 away from the guide sleeve 18 and abut against the side of the first positioning element 22, respectively. Alternatively, the two ends of the first elastic element 24 are connected to the side of the first positioning element 22 facing the guide sleeve 18 and the side of the guide sleeve 18, respectively. It should be noted that the first elastic element 24 is in a stretched state at this time. Both of the above installation methods of the first elastic element 24 will apply a spring force to the first positioning element 22 pointing towards the guide sleeve 18, so that when no external force is applied, the first locking block 21 is pushed into the first positioning groove 17 by the spring force of the first elastic element 24, thereby completing the locking.

[0066] Furthermore, in some embodiments, to facilitate the release of the self-locking state of the first limiting sleeve 19, such as... Figures 5 to 6 As shown, a collection and analysis device further includes a first adjustment component, which includes a first adjustment member 27. The first adjustment member 27 is movably installed between the first positioning member 22 and the guide sleeve 18. The side of the first adjustment member 27 facing the guide sleeve 18 abuts against the side of the guide sleeve 18. The side of the first adjustment member 27 away from the guide sleeve 18 includes a first plane, a first inclined plane, and a second plane. The first plane is parallel to the second plane, and the first plane abuts against the side of the first positioning member 22 facing the guide sleeve 18. The second plane protrudes from the first plane on the side away from the guide sleeve 18. The first plane is smoothly connected to the second plane through the first inclined plane. The distance between the second plane and the first plane is configured such that when the side of the first positioning member 22 facing the guide sleeve 18 abuts against the second plane, the first locking block 21 separates from the first positioning groove 17.

[0067] In this embodiment, the collection and analysis device adopts the design of a first adjusting member 27 with a first plane, a first inclined plane and a second plane, which enables the first locking block 21 to separate from the first positioning groove 17, thereby releasing the self-locking state of the first limiting sleeve 19. This technical means effectively solves the problem of complex and inefficient operation of releasing the self-locking state in the prior art, thereby realizing convenient release of the self-locking state, improving the flexibility and convenience of operation, and enhancing the adjustment performance and adaptability of the device.

[0068] In some embodiments, such as Figures 5 to 7As shown, there are two first positioning members 22. In order to achieve the purpose of quick unlocking, the number of first adjusting members 27 should also be the same as that of the first positioning members 22. In addition, in order to facilitate the simultaneous control of the two first adjusting members 27 to move at the same time, the two first adjusting members 27 can be connected into one piece by the push plate 26, so that the two first positioning members 22 can be pushed to move together while the push plate 26 is pushed.

[0069] In some embodiments, to avoid the problem of mis-locking of the first limiting sleeve 19, such as Figure 5 As shown, the first adjustment assembly also includes a second elastic element 28. The first adjustment element 27 is connected to the guide sleeve 18 through the second elastic element 28. The second elastic element 28 applies elastic force to the first adjustment element 27 so that the second plane of the first adjustment element 27 tends to move away from the first positioning element 22.

[0070] In this embodiment, the collection and analysis device employs a design where the second elastic element 28 applies elastic force to the first adjusting element 27, causing the second plane of the first adjusting element 27 to tend to move away from the first positioning element 22. This effectively avoids the problem of mis-locking of the first limiting sleeve 19. This technical means effectively solves the problem of misoperation or mis-locking that may occur when releasing the self-locking mechanism in the prior art, thereby achieving operational stability and safety, and improving the reliability of the device and the user experience.

[0071] In some embodiments, a limiting rod 25 for restricting the movement trajectory is fixedly connected to the side of the guide sleeve 18. A limiting hole is provided on the push plate 26, and the limiting rod 25 is inserted into the limiting hole so that the push plate 26 can slide relative to the limiting rod 25. To prevent the first limiting sleeve 19 from mis-locking, a second elastic element 28 is sleeved on the outside of the limiting rod 25. The second elastic element 28 can be selected as a spring, and its two ends abut against the limiting structure at the end of the limiting rod 25 away from the guide sleeve 18 and the side of the guide sleeve 18, respectively. When it is necessary to lower the guide sleeve 18 during use, the first locking block 21 can be separated from the first positioning groove 17 by pushing the push plate 26. During this process, the push plate 26 will also compress the second elastic element 28 at the same time as it moves. After moving to the unlocked position, the guide sleeve 18 is adjusted to move along the axial direction of the first guide shaft 2. Then, the push plate 26 can be released to automatically reset the push plate 26 under the action of the second elastic element 28, so that the first locking block 21 can be re-engaged with the first positioning groove 17 at another position to prevent the guide sleeve 18 from accidentally slipping off.

[0072] In some embodiments, to enable the first limiting sleeve 19 to move rapidly along the first guide shaft 2 in a direction away from the main body 1, such as... Figure 6As shown, the first locking block 21 has a retaining slope on the side away from the main body 1. The retaining slope abuts against the inner wall of the first through groove 20. The retaining slope is configured such that when the guide sleeve 18 has a tendency to move in the direction away from the main body 1, the first locking block 21 has a tendency to move in the direction away from the guide sleeve 18 under the action of the retaining force applied by the inner wall of the first through groove 20.

[0073] In this embodiment, the collection and analysis device employs a design where the inclined surface abuts against the inner wall of the first through groove 20. This design allows the first locking block 21 to move rapidly away from the guide sleeve 18 as the guide sleeve 18 moves away from the main body 1, thanks to the supporting force. This technique effectively solves the problem of lag or jamming that may occur during the movement of the first limiting sleeve 19 in the prior art, thereby achieving rapid and stable movement of the first limiting sleeve 19 and improving the adjustment efficiency and ease of operation of the device.

[0074] like Figure 4 As shown, a second through groove 5 is provided on the outer side of the second guide shaft 3, and the second through groove 5 extends along the axial direction of the second guide shaft 3. The sliding sleeve assembly includes a first sliding member 11 and a connecting member 10. The first sliding member 11 is disposed on the side of the second guide shaft 3 away from the main body 1, and the first sliding member 11 moves along the axial direction of the second guide shaft 3. One side of the connecting member 10 is connected to the first sliding member 11, and the connecting member 10 is inserted into the second through groove 5 so that it moves within the second through groove 5 when the sliding sleeve assembly moves along the axial direction of the second guide shaft 3. The side of the connecting member 10 away from the first sliding member 11 is connected to the second limiting sleeve 13 so that the second limiting sleeve 13 moves together with the connecting member 10.

[0075] In this embodiment, the collection and analysis device employs a design with a second through groove 5 and a connecting piece 10, enabling the sliding sleeve assembly to move stably axially along the second guide shaft 3. Furthermore, the connecting piece 10 connects it to the second limiting sleeve 13, ensuring that the second limiting sleeve 13 adjusts synchronously with the movement of the sliding sleeve assembly. This technique effectively solves the problem of unstable adjustment of the second limiting sleeve 13 in the prior art, thereby achieving precise coordinated movement between the sliding sleeve assembly and the second limiting sleeve 13, improving the adjustment accuracy and operational stability of the device.

[0076] In some embodiments, to allow the second limiting sleeve 13 to move in a controlled manner, such as Figures 1-4As shown, a second positioning groove 7 is formed on the outer side of the second guide shaft 3. The connecting member 10 extends to the outside of the second through groove 5 from the side opposite to the first sliding member 11. The collection and analysis device also includes a second positioning assembly, which includes a second positioning member 12, a second sliding member 8, and a third elastic member 16. The second positioning member 12 is adapted to the second positioning groove 7. The second positioning member 12 is disposed on the side of the first sliding member 11 facing the second guide shaft 3. The second sliding member 8 is disposed outside the second guide shaft 3 and is configured to move along the axial direction of the second guide shaft 3. The first sliding member 11 is connected to the second sliding member 8 through the third elastic member 16. The third elastic member 16 applies a force to the first sliding member 11 pointing towards the second guide shaft 3, causing the second positioning member 12 to engage with the second positioning groove 7 to restrict the movement of the first sliding member 11. The distance by which the connecting member 10 extends to the outside of the second through groove 5 is configured such that when the second limiting sleeve 13 abuts against the second guide shaft 3, the second positioning member 12 separates from the second positioning groove 7.

[0077] In this embodiment, the collection and analysis device employs a design of a second positioning member 12, a second sliding member 8, and a third elastic member 16. This design allows the second positioning member 12 to precisely engage with the second positioning groove 7, thereby restricting the movement of the first sliding member 11. Simultaneously, the connecting member 10 extends to the outside of the second through groove 5, ensuring effective contact between the second limiting sleeve 13 and the second guide shaft 3, preventing mis-engagement or failure of the positioning components. This technical approach effectively solves the problem of unstable movement or mispositioning of the second limiting sleeve 13 in the prior art, thereby achieving precise control and stable movement of the second limiting sleeve 13, and improving the adjustment accuracy and reliability of the collection and analysis device.

[0078] In some embodiments, a sliding groove 6 is provided on the side of the second guide shaft 3, and a fitting member is constructed on the side of the second sliding member 8 facing the second guide shaft 3 to fit into the sliding groove 6, so that the second sliding member 8 is slidably connected to the second guide shaft 3, and the second sliding member 8 can only move along the extension direction of the sliding groove 6 under the cooperation of the fitting member and the sliding groove 6, and the extension direction of the sliding groove 6 is parallel to the axial direction of the second guide shaft 3.

[0079] Furthermore, in some embodiments, to make the second slider 8 move synchronously with the first slider 11, such as... Figures 2 to 3 As shown, the second sliding member 8 is also provided with a limiting groove 9. When the second sliding member 8 is connected to the first sliding member 11, the connecting member 10 is engaged in the limiting groove 9 to install the second sliding member 8 on the first sliding member 11, so that the second sliding member 8 can move synchronously with the first sliding member 11.

[0080] Furthermore, in some embodiments, such as Figure 2As shown, sliding blocks 14 are constructed on both opposite sides of the connector 10. A sliding guide groove 15 is provided on the inner wall of the second sliding member 8 at the position corresponding to the sliding block 14. The extending direction of the sliding guide groove 15 is parallel to the axial direction of the first guide shaft 2. The sliding block 14 is movably embedded in the sliding guide groove 15. A third elastic member 16 is disposed in the sliding guide groove 15. The two ends of the third elastic member 16 abut against the inner wall of the sliding guide groove 15 and the sliding block 14 respectively, so as to apply an elastic force away from the second guide shaft 3 to the sliding block 14, thereby enabling the sliding sleeve assembly to achieve self-locking.

[0081] When the collection and analysis device of this application is in use, the horizontal position of the second limiting sleeve 13 can be adjusted by pushing the second limiting sleeve 13 upward. As the second limiting sleeve 13 moves, it synchronously drives the connecting member 10 to move. After the connecting member 10 moves, it synchronously drives the sliding block 14 to move. After the sliding block 14 moves, it presses against the third elastic member 16. Simultaneously, as the connecting member 10 moves, it synchronously drives the second positioning member 12 to move with the help of the first sliding member 11. After the second positioning member 12 moves, it disengages from the second positioning groove 7. At this point, the second limiting sleeve 13 can be slid left and right. When sleeve 13 slides, it simultaneously drives the second sliding member 8 to slide. After sliding to the designated position, by releasing the second limiting sleeve 13, the second limiting sleeve 13 drives the connecting member 10 to descend. At the same time, the third elastic member 16 also pushes the sliding block 14 to reset, thereby driving the first sliding member 11 and the second positioning member 12 to reset through the connecting member 10. After the second positioning member 12 resets, it re-locks into the second positioning groove 7, thus completing the position locking. When the first limiting sleeve 19 moves upward, it can be moved by directly pushing the first limiting sleeve 19 upward. When the first limiting sleeve 19 moves, it simultaneously drives the connecting member 10 to descend. The guide sleeve 18 drives the first locking block 21 to move. Since the upper surface of the first locking block 21 is a retaining slope, when the first locking block 21 moves, it is pressed by the first positioning groove 17, causing the first locking block 21 to disengage from the first positioning groove 17. Simultaneously, the first positioning member 22 stretches the first elastic member 24, allowing the first limiting sleeve 19 to move freely. After moving and realigning with the first positioning groove 17, the elastic force of the first elastic member 24 pushes the first locking block 21 back into the first positioning groove 17, thus completing the locking process. When the guide sleeve 18 needs to be lowered, the push plate 26 is pushed, and the push plate 26 simultaneously drives the first adjusting member 27 to move. After the first adjusting member 27 moves, the first inclined surface contacts the first positioning member 22, thereby pushing the first positioning member 22 to move horizontally. When the first positioning member 22 moves, it will simultaneously drive the first locking block 21 to move. When the first locking block 21 moves, it will disengage from the first positioning groove 17. When the push plate 26 moves, it will also simultaneously compress the second elastic member 28. After moving to the designated location, the push plate 26 can be reset. In summary, the above settings can facilitate the analysis and collection of data and improve the effect of analysis and collection.
