Technical Field
[0001] This invention relates to the field of electroencephalogram (EEG) acquisition equipment technology, and in particular to a portable EEG acquisition equipment conversion device. Background Technology
[0002] The electroencephalogram (EEG) acquisition device consists of a motherboard, a bioelectric chip, control buttons, a wireless transmission module, electrode wires, and electrodes. It is capable of guiding human or animal brainwaves through electrodes into the device, where they are filtered, amplified, and digitized by the bioelectric chip before being wirelessly transmitted to a computer.
[0003] A patent application with application number 201720827681.8 and authorization announcement date of April 6, 2018, discloses a portable EEG acquisition device conversion device. The device includes a conversion unit and a portable EEG acquisition device connected to the conversion unit. The conversion unit has a housing with a guide rail. The portable EEG acquisition device is slidably mounted on the conversion unit via the guide rail. A high-density male interface is provided on the side of the conversion unit that interfaces with the portable EEG acquisition device. A high-density female interface is provided on the portable EEG acquisition device corresponding to the male interface. The conversion unit also has a Touchproof interface array and a built-in battery connected to the high-density male interface. This invention effectively routes the electrode pathways between the EEG device and a traditional EEG cap, and provides additional power to the portable EEG device, extending its operating time.
[0004] Although the portable EEG acquisition device conversion device can perform conversion and connection work, during operation, the conversion device and the portable EEG acquisition device are only connected through male and female ports. During this process, the male and female ports will be subjected to great pressure. Especially when the user is carrying the device, the male port is very easy to break inside the female port, thus rendering the device unusable. The wear rate of device parts is high. To address this, we propose a portable EEG acquisition device conversion device. Summary of the Invention
[0005] To address the technical problem of high wear and tear rate of components in portable EEG acquisition device conversion devices, this invention provides a portable EEG acquisition device conversion device.
[0006] This invention is achieved using the following technical solution: A portable EEG acquisition device conversion device includes a loading box and a handle fixed to one end of the loading box. A mounting plate is provided above the loading box, and a connecting assembly for connecting the mounting plate is also provided on the loading box. A conversion device is provided on one side of the mounting plate. An EEG acquisition device is slidably connected inside the conversion device.

Slots are provided at the opposite ends of the conversion device and the EEG acquisition device. The strip engages with the corresponding slot. The inner wall of the protective shell has multiple connecting teeth that mesh with the connecting gears. The protective shell also contains protective components. The EEG acquisition device can be supported by the carrier plate on the conversion device. The conversion device and the EEG acquisition device can be connected through the male connector on the conversion device and the female connector on the EEG acquisition device to perform information conversion. When the male connector on the conversion device is inserted into the female connector on the EEG acquisition device, the connecting strip will enter the slot, limiting the conversion device and the EEG acquisition device, reducing the pressure on the male and female connectors, and preventing the male connector from breaking inside the female connector when the user is carrying the device, thus reducing the wear rate of the device components.
[0007] As a further improvement to the above solution, the protective assembly includes a shield hinged to the inner wall of the protective shell. The shield is used to block the connection port of the conversion device and the EEG acquisition device. A connecting plate is hinged to the outer side of the shield, and a connecting block is hinged to the movable end of the connecting plate. A sliding groove is formed on the inner wall of the protective shell, and a slider is slidably connected inside the sliding groove. Multiple connecting springs fixed to the slider are fixed to the inner wall of the end of the sliding groove. Both the conversion device and the EEG acquisition device have sliding grooves, and sliding blocks are slidably connected inside the sliding grooves. A stabilizing block fixed to an adjacent protective shell is fixed on the sliding block. A connecting post one is fixed to one end of the protective shell outside the EEG acquisition device, and a connecting post two is fixed to the other end of the protective shell outside the EEG acquisition device. A loading plate is provided on the side of the conversion device away from the mounting plate. A rotating hole one is formed at the end of both the mounting plate and the loading plate near the EEG acquisition device. The connecting post one and the connecting post two...

An extension block is fixed at the other end of the linkage block away from the linkage spring. The other end of the linkage spring away from the linkage block is fixed to the loading plate. Through the cooperation of the protective components, the connection port of the conversion device and the EEG acquisition device can be blocked and protected to prevent external debris and dust from entering the connection port of the conversion device and the EEG acquisition device, thereby improving the protective performance of the device. Moreover, the conversion device and the EEG acquisition device can be flexibly adjusted according to the usage requirements.
[0008] As a further improvement to the above solution, the connecting assembly includes a support plate fixed to the inner wall of the loading box.

When the male connector on the conversion device 3 is inserted into the female connector on the EEG acquisition device 4, the connecting rack 17 will enter the slot 20 to limit the conversion device 3 and the EEG acquisition device 4, reduce the pressure on the male and female connectors, and prevent the male connector from breaking inside the female connector when the user is carrying the device, thereby reducing the wear rate of the device components.
[0034] Example 2:
[0035] Combination Figure 2 , 4-8. This embodiment, based on embodiment 1, further improves upon the following: the protective component includes a shield 6 hinged to the inner wall of the protective shell 5. The shield 6 is used to block the connection port between the conversion device 3 and the EEG acquisition device 4. A connecting plate 7 is hinged to the outer side of the shield 6. A connecting block 10 is hinged to the movable end of the connecting plate 7. A sliding groove 8 is provided on the inner wall of the protective shell 5. A slider 9 is slidably connected inside the sliding groove 8. Multiple connecting springs 11 fixed to the slider 9 are fixed to the inner wall at the end of the sliding groove 8. Both the conversion device 3 and the EEG acquisition device 4 are provided with sliding grooves. A sliding block is slidably connected inside the sliding groove. A stabilizing block fixed to an adjacent protective shell 5 is fixed on the sliding block. A connecting post 13 is fixed to one end of the protective shell 5 located outside the EEG acquisition device 4. A connecting post 15 is fixed to the other end of the protective shell 5 outside the EEG acquisition device 4. A loading plate 12 is provided on the side of the conversion device 3 away from the mounting plate 2. A rotating hole 1 is provided at the end of both the mounting plate 2 and the loading plate 12 near the EEG acquisition device 4. Connecting posts 13 and 25 rotate within adjacent rotating holes 1. A connecting post 3 14 is fixed to one end of the protective shell 5 outside the conversion device 3. A rotating hole 2 is provided at the end of the mounting plate 2 near the conversion device 3. Connecting post 3 14 rotates within rotating hole 2. A connecting block 21 is fixed to the end of the mounting plate 2 near the EEG acquisition device 4. A receiving groove 22 is provided on the inner wall of the connecting block 21. A connecting block 23 is slidably connected inside the receiving groove 22. Multiple fixed blocks are fixed to the inner wall of the end of the receiving groove 22. The linkage block 23 has a linkage spring 25. An extension block 24 is fixed to the other end of the linkage block 23 away from the linkage spring 25. The other end of the linkage spring 25 away from the linkage block 23 is fixed to the loading plate 12. The shield 6 can block and protect the connection port between the conversion device 3 and the EEG acquisition device 4, preventing external debris and dust from entering the connection port and improving the device's protective performance. When the device needs to be used, the loading plate 12 can be pulled, causing it to move vertically. When the connecting column 3 14 disengages from the rotating hole 2, the conversion device 3 and the EEG acquisition device 4 can be pushed, causing them to deflect. When the conversion device 3 and the EEG acquisition device 4 are in contact with the mounting plate 2... After the loading plate 12 is misaligned, the conversion device 3 can be pushed. When the male head of the conversion device 3 is inserted into the female head of the EEG acquisition device 4, the connecting rack 17 will enter the slot 20. At this time, the connecting rack 17 will be displaced by the thrust. When the connecting rack 17 meshes with the connecting gear 18, the displaced connecting rack 17 will drive the connecting gear 18 to rotate. The rotating connecting gear 18 will drive the protective shell 5 to move by working with the connecting gear. The displaced protective shell 5 will drive the cover plate 6 to deflect, causing the cover plate 6 to open the connection port between the conversion device 3 and the EEG acquisition device 4. At this time, the user can use the connection port between the conversion device 3 and the EEG acquisition device 4.
[0036] Furthermore, when the user needs to detach the conversion device 3 and the EEG acquisition device 4 from the protective assembly, the loading plate 12 can be pulled to move the loading plate 12 vertically. After the connecting column 3 14 is disengaged from the interior of the rotating hole 2, the conversion device 3 and the EEG acquisition device 4 can be pulled. After the connecting column 1 13 is disengaged from the interior of the rotating hole 1, the conversion device 3 and the EEG acquisition device 4 can be pulled horizontally. After the conversion device 3 and the EEG acquisition device 4 are separated from the loading plate 12 and the mounting plate 2, the user can then use the conversion device 3 and the EEG acquisition device 4.
[0037] Example 3:
[0038] Combination Figure 3 and Figure 9This embodiment, based on embodiment 2, further improves upon the following: the connecting assembly includes a support plate 38 fixed to the inner wall of the loading box 1. A loading block 35 is hinged to the end of the support plate 38 away from the loading box 1. A mounting plate 2 is fixed to the loading block 35. The loading block 35 has a sliding groove 33, and a sliding block 32 is slidably connected inside the sliding groove 33. The loading plate 12 is fixed to the sliding block 32 and slides inside the opening of the sliding groove 33. A motor 27 is fixed to the inner wall of the end of the loading box 1. The motor 27 is a forward and reverse reversible motor, and its output end drives... A lead screw 28 is rotatably connected to the inner wall of the loading box 1. A drive sleeve is threaded onto the outer wall of the lead screw 28. A transmission plate 36 is hinged to the outer side of the drive sleeve. The movable end of the transmission plate 36 is hinged to the outer side of the movable end of the loading block 35. An opening 37 is provided on the top of the loading box 1. The mounting plate 2 and the loading plate 12 slide with the opening 37. A closing plate 29 is provided on the top of the loading box 1 to close the opening 37. A transmission shaft 34 is rotatably connected to the inner wall of the loading box 1 and fixed to the end of the closing plate 29. A bevel gear is fixedly sleeved on the outer wall of the transmission shaft 34. The outer wall of the lead screw 28 is fixedly... A bevel gear two, which meshes with bevel gear one, is fixedly sleeved. The motor 27 drives the lead screw 28 to rotate. The rotating lead screw 28, through its threaded engagement with the drive sleeve, causes the drive sleeve to shift, leading to the deflection of the transmission plate 36. This deflection of the transmission plate 36 then causes the loading block 35 to deflect, which in turn causes the loading plate 12 and mounting plate 2 to deflect, consequently causing the conversion device 3 and the EEG acquisition device 4 to deflect. When the conversion device 3 and the EEG acquisition device 4 enter the loading box 1 through the opening 37... After being placed inside the loading box 1, the conversion device 3 and the EEG acquisition device 4 are collected inside the loading box 1. When the lead screw 28 rotates, it will drive the bevel gear 2 to rotate. At this time, the rotating bevel gear 2 can drive the bevel gear 1 to rotate, which in turn drives the transmission shaft 34 to rotate. The rotating transmission shaft 34 will drive the sealing plate 29 to rotate. After the conversion device 3 and the EEG acquisition device 4 are collected inside the loading box 1, the rotating sealing plate 29 will close the opening 37, thereby effectively storing and protecting the conversion device 3 and the EEG acquisition device 4.
[0039] The loading box 1 has a loading hole, and the transmission shaft 34 rotates inside the loading hole. Through the loading hole, the transmission shaft 34 can rotate flexibly.
[0040] The length of the loading box 1 is greater than the length of the mounting plate 2, and the length of the opening 37 is greater than the length of the mounting plate 2. The mounting plate 2 can be flexibly deflected through the opening 37, which is longer than the length of the mounting plate 2.
[0041] The inner wall of the loading box 1 is hinged with a crash plate 30, and multiple buffer springs 31 are fixed to the crash plate 30 on the inner wall of the loading box 1. When the conversion device 3 and the EEG acquisition device 4 enter the interior of the loading box 1, the crash plate 30 can protect the conversion device 3 and the EEG acquisition device 4, preventing the deflected conversion device 3 and the EEG acquisition device 4 from having a hard collision with the inner wall of the loading box 1, thus effectively protecting the conversion device 3 and the EEG acquisition device 4.
[0042] A hinged door is provided on one side of the loading box 1, and a sealing ring is provided on the outside of the door. An observation window is installed on the other side of the loading box 1. By opening the door, the user can easily operate the components inside the loading box 1.
[0043] The depth of the receiving groove 22 is greater than the length of the linkage block 23. The linkage block 23 is a rectangular block. The height of the protective shell 5 is greater than the length of the connecting block 21. The linkage block 23 can be effectively stored through the receiving groove 22, which is deeper than the length of the linkage block 23.
[0044] The connecting block 21 is offset from the cover plate 6. The connecting rack 17 has a through hole. A guide rod 19 fixed to the inner wall of the mounting groove 16 slides through the through hole. A push spring 26 is sleeved on the outside of the guide rod 19. The connecting rack 17 can be flexibly moved through the through hole.
[0045] The length of connecting column 2 15 is greater than the length of connecting column 3 14, and the length of sliding groove 33 is greater than the thickness of loading plate 12. Through sliding groove 33, which is longer than the thickness of loading plate 12, loading plate 12 can be vertically displaced.
[0046] Working principle: The shield 6 can block and protect the connection port of the conversion device 3 and the EEG acquisition device 4, preventing external debris and dust from entering the connection port and improving the device's protective performance. When the device needs to be used, the loading plate 12 can be pulled, causing it to move vertically. After the connecting post 3 14 is disengaged from the rotating hole 2, the conversion device 3 and the EEG acquisition device 4 can be pushed, causing them to deflect. When the conversion device 3 and the EEG acquisition device 4 are misaligned with the mounting plate 2 and the loading plate 12, the conversion device 3 can be pushed. When the male connector on the conversion device 3 is inserted into the female connector on the EEG acquisition device 4, information conversion can begin. When the male connector on the conversion device 3 is inserted into the female connector on the EEG acquisition device 4, the connecting rack 17 will enter the slot 20, restricting the conversion device 3 and the EEG acquisition device 4, reducing pressure on the male and female connectors, and preventing the male connector from breaking inside the female connector when the user is carrying the device, thus reducing the wear rate of device components. After the connecting rack 17 enters the slot 20, it will be displaced by the pushing force. When the connecting rack 17 meshes with the connecting gear 18, the displaced connecting rack 17 will drive the connecting gear 18 to rotate. The rotating connecting gear 18, through its interaction with the connecting rack, will drive the protective shell 5 to move. The displaced protective shell 5 will... The movable cover 6 deflects, opening the connection port between the conversion device 3 and the EEG acquisition device 4. At this time, the user can use the connection port of the conversion device 3 and the EEG acquisition device 4. When the user needs to detach the conversion device 3 and the EEG acquisition device 4 from the protective assembly, they can pull the loading plate 12, causing it to move vertically. After the connecting post 3 14 disengages from the interior of the rotating hole 2, the conversion device 3 and the EEG acquisition device 4 can be pulled. After the connecting post 1 13 disengages from the interior of the rotating hole 1, the conversion device 3 and the EEG acquisition device 4 can be pulled horizontally. After the conversion device 3 and the EEG acquisition device 4 are separated from the loading plate 12 and the mounting plate 2, the user can then use the conversion device 3 and the EEG acquisition device 4 via the motor. When 27 is activated, the drive screw 28 rotates. The screw 28 engages with the threaded drive sleeve, causing it to shift and deflect the transmission plate 36. This deflection of the transmission plate 36 then deflects the loading block 35, which in turn deflects the loading plate 12 and mounting plate 2, consequently the conversion device 3 and the EEG acquisition device 4. Once the conversion device 3 and the EEG acquisition device 4 enter the loading box 1 through the opening 37, they are collected inside. Furthermore, the rotation of the screw 28 drives the bevel gear 2, which in turn drives the bevel gear 1 to rotate.The drive shaft 34 rotates, which in turn causes the sealing plate 29 to rotate. Once the conversion device 3 and the EEG acquisition device 4 are collected inside the loading box 1, the rotating sealing plate 29 closes the opening 37, effectively protecting and storing the conversion device 3 and the EEG acquisition device 4.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
