Description

Memory training device

[0001] This application claims priority to Chinese patent application number 202410169922.9, filed on February 6, 2024, entitled “A Memory Training Device”, the disclosure of which is incorporated herein by reference. Technical Field

[0002] The present application belongs to the field of mechanical technology, and specifically relates to a memory training device. Background Art

[0003] Active recall methods focus on active participation by the individual, that is, actively extracting information from the brain, which helps strengthen the relevant memory neural connections. By actively recalling and retelling information, this method promotes memory enhancement and effectively stimulates the brain's memory retrieval and storage capabilities. Some related technologies use active recall methods to train memory, but some devices have complex structures. Others offer a poor user experience and fail to effectively train memory.

[0004] Therefore, there is a need in the art for a memory training device with a simpler structure and better user experience. Summary of the Invention

[0005] In view of the problems existing in the above-mentioned prior art, a memory training device is proposed. The memory training device has a relatively simple structure and a good user experience.

[0006] This application provides the following solutions.

[0007] In a first aspect, the present application provides a memory training device comprising: a cylindrical housing and a plurality of memory pieces, the cylindrical housing comprising a storage cylinder and a memory piece outlet selection ring axially connected to each other and rotatable relative to each other about an axis; wherein,

[0008] The storage barrel is used to accommodate a plurality of memory chips therein and enable the memory chips to move axially along the storage barrel, and the storage barrel is provided with a memory chip inlet at a first end portion in the axial direction and connected to a first end portion of a memory chip outlet selection ring at a second end portion opposite to the first end portion;

[0009] The memory piece outlet selection ring is provided with a memory piece outlet at a second end portion opposite to the first end portion thereof;

[0010] Different memory marks are sequentially arranged on the edge of the memory sheet along the circumferential direction, and different memory marks are sequentially arranged on the outer surface of the cylindrical shell along the circumferential direction;

[0011] The memory chip outlet selection ring is rotated to different angles relative to the storage tube to indicate different memory marks set on the cylindrical shell. When the memory chip outlet selection ring is rotated so that the memory mark it indicates matches the target memory mark on the target memory chip, the target memory chip can pass through the second end of the storage tube into the memory chip outlet selection ring and exit from the memory chip outlet, wherein the target memory chip is the memory chip closest to the memory chip outlet in the storage tube.

[0012] In some possible embodiments, one of the memory plate and the memory plate outlet selection ring is provided with an axially penetrating and radially open positioning groove, and the other is provided with a positioning protrusion matching the positioning groove;

[0013] When the memory chip outlet selection ring is rotated so that the memory mark indicated by it matches the target memory mark on the target memory chip, the positioning protrusion can pass through the positioning groove, thereby allowing the target memory chip passing through the second end of the storage cartridge to enter the memory chip outlet selection ring and exit from the memory chip outlet.

[0014] In some possible embodiments, when the memory chip outlet selection ring is rotated so that the memory mark indicated by it does not match the target memory mark on the target memory chip, the positioning protrusion blocks the target memory chip and prevents it from leaving the memory chip outlet.

[0015] In some possible embodiments, the storage cartridge is further provided with an alternating blocking member at its second end, which switches between at least two blocking positions for selectively blocking the corresponding memory piece from passing through the second end of the storage cartridge and entering the memory piece outlet selection ring.

[0016] In some possible embodiments, the alternating blocking member switches between a first blocking position and a second blocking position, and the multiple memory pieces include a first type of memory piece and a second type of memory piece. When the alternating blocking member is in the first blocking position, it can block the first type of memory piece from passing through the second end of the storage barrel into the memory piece outlet selection ring and allow the second type of memory piece to pass through the second end of the storage barrel into the memory piece outlet selection ring. When the alternating blocking member is in the second blocking position, it can block the second type of memory piece from passing through the second end of the storage barrel into the memory piece outlet selection ring and allow the first type of memory piece to pass through the second end of the storage barrel into the memory piece outlet selection ring.

[0017] In some possible embodiments, the alternating blocking member is annular, sleeved on the second end of the storage cartridge, and rotatable relative to the second end of the storage cartridge between a first blocking position and a second blocking position. At least one blocking protrusion extending radially inward is provided on the inner wall of the alternating blocking member. The edge of the first type memory plate is provided with the same number of circumferentially penetrating and radially open first alternating grooves as the number of different memory marks. The edge of the second type memory plate is provided with the same number of circumferentially penetrating and radially open second alternating grooves as the number of different memory marks. The size of the blocking protrusion is such that it can pass through the first and second alternating grooves.

[0018] When the alternating blocking member is in the first blocking position, the blocking protrusion is misaligned with the corresponding first alternating groove and aligned with the corresponding second alternating groove; when the alternating blocking member is in the second blocking position, the blocking protrusion is misaligned with the corresponding second alternating groove and aligned with the corresponding first alternating groove;

[0019] Preferably, the memory plate outlet selection ring is sleevedly connected to the alternating blocking member and is circumferentially rotatable relative to the alternating blocking member.

[0020] In some possible embodiments, the different memory marks provided on the cylindrical housing are located on the outer side of the alternating blocking members and are arranged in an order opposite to the order of the memory marks on the memory sheet along the circumferential direction.

[0021] In some possible embodiments, when the memory chip exit selection ring is rotated so that the memory mark indicated by it does not match the target memory mark on the target memory chip, the target memory chip can only partially enter the memory chip exit selection ring, and is thereby stuck at the first end of the memory chip exit selection ring and cannot leave the memory chip exit.

[0022] In some possible embodiments, the positioning protrusion includes a protrusion extension with a reduced transverse dimension on a side facing the positioning groove. At least one sliding groove is further provided on one of the memory plate and the memory plate outlet selection ring, which allows the protrusion extension to enter but does not allow the positioning protrusion to enter as a whole. When the memory plate outlet selection ring is rotated so that the memory mark indicated by it does not match the target memory mark on the target memory plate, only the protrusion extension enters the sliding groove at the corresponding position, causing a jam.

[0023] Alternatively, a first sliding groove and at least one second sliding groove are provided on one of the memory piece and the memory piece outlet selection ring, and a stepped protrusion is provided on the other of the memory piece and the memory piece outlet selection ring. The size of the stepped protrusion is such that it can enter the first sliding groove as a whole but can only partially enter the second sliding groove. When the memory piece outlet selection ring is rotated so that the memory mark indicated by it matches the target memory mark on the target memory piece, the stepped protrusion enters the first sliding groove as a whole, thereby allowing the memory piece to enter the memory piece outlet selection ring and leave the memory piece outlet; when the memory piece outlet selection ring is rotated so that the memory mark indicated by it does not match the target memory mark on the target memory piece, the stepped protrusion partially enters the second sliding groove and becomes stuck.

[0024] In some possible embodiments, the central portion of the positioning protrusion of the memory chip inlet selection ring is made of a hard material, and the edge portion of the positioning protrusion of the memory chip inlet selection ring is made of a flexible material;

[0025] The area of ​​the central portion of the positioning protrusion of the memory plate inlet selection ring in the circumferential plane is smaller than the area of ​​the positioning groove in the circumferential plane;

[0026] The area of ​​the positioning protrusion including the edge portion in the circumferential plane is larger than the area of ​​the positioning groove in the circumferential plane;

[0027] The memory piece rotates relative to the memory piece inlet selection ring so that the edge portion is compressed when the positioning groove is aligned with the positioning protrusion, so that the memory piece can pass through the memory piece inlet selection ring and enter the storage cylinder.

[0028] In some possible embodiments, at least one guide rail is provided on the inner wall of the storage barrel, for passing through corresponding sliding grooves and / or positioning grooves provided on the memory piece, so that the memory piece can move axially along the storage barrel.

[0029] In some possible embodiments, the cylindrical housing further includes an end support cylinder axially disposed at the first end of the storage cylinder for accommodating an axial thrust block therein; the axial thrust block is axially movable relative to the end support cylinder.

[0030] In some possible embodiments, an elastic component is provided between the end support cylinder and the axial thrust block, for applying elastic force to the axial thrust block so that the axial thrust block is axially pressed against the memory piece in the storage cylinder;

[0031] The axial thrust block is provided with a pulling protrusion extending through the end support tube; or, a sliding groove is provided on the side wall of the end support tube for the pulling protrusion to move axially therein.

[0032] In some possible embodiments, the axial thrust block is provided with a handle passing through the end of the terminal support tube, and the handle is used for a user to pull to make the axial thrust block move axially in the terminal support tube;

[0033] Preferably, the storage cylinder is axially provided with a first guide rail and a second guide rail in sequence, the first guide rail and the second guide rail are on the same straight line, and the second guide rail is wider than the first guide rail, the axial thrust block is coaxial with the end support cylinder, and the outer surface of the end support cylinder is provided with a first groove and a second groove;

[0034] When the user pulls the handle, the first groove slides along the first guide rail; when the axial thrust block and the end support cylinder are pulled to the bottom end, the second guide rail abuts against the first groove;

[0035] A sliding gap is provided between the first guide rail and the second guide rail, and when the end support cylinder is pulled to the bottom end, the sliding gap enables the end support cylinder to rotate circumferentially relative to the storage cylinder;

[0036] The second groove is axially connected to the first groove, and the second groove is wider than the first groove. When the end support cylinder rotates axially relative to the storage cylinder, the second guide rail rotates in the second groove. The positions of the first groove and the first guide rail are staggered, so that the end support cylinder is stuck in the axial direction, and the axial thrust block and the end support cylinder can rotate relative to each other.

[0037] In some possible embodiments, it is characterized in that one end of the axial thrust block close to the memory plate is used for anti-rotation cooperation with the central part of the memory plate;

[0038] The axial thrust block is rotatable relative to the storage barrel in a circumferential direction, so that one end of the axial thrust block close to the memory plate enters into anti-rotation cooperation with the central portion of the memory plate.

[0039] In some possible embodiments, a memory piece inlet selection ring is further included, which is disposed in a circumferential sliding track formed on the inner wall of the second end portion of the storage barrel and is rotatable relative to the storage barrel about an axis.

[0040] The memory chip inlet selection ring is radially formed with a positioning protrusion that matches the positioning groove on the memory chip. When the memory chip rotates relative to the memory chip inlet selection ring so that the positioning groove on the memory chip is aligned with the positioning protrusion of the memory chip inlet selection ring, the memory chip can pass through the memory chip inlet selection ring and enter the storage cylinder.

[0041] An axial protrusion is provided on the side of the memory piece inlet selection ring facing the memory piece outlet, and a slope is provided on the side wall of the sliding track facing the axial protrusion. When the memory piece inlet selection ring rotates relative to the storage cylinder along a first circumferential direction, the axial protrusion repeats the process of climbing and falling on the slope. When the memory piece inlet selection ring rotates relative to the storage cylinder along a second circumferential direction opposite to the first circumferential direction, the axial protrusion is stuck by the slope.

[0042] In some possible embodiments, the positioning protrusion of the memory piece inlet selection ring at least partially extends out of a flexible portion made of a flexible material along its circumference;

[0043] When the positioning groove of the memory piece adjacent to the memory piece inlet selection ring in the storage cartridge is axially aligned with the positioning protrusion of the memory piece inlet selection ring, the flexible portion is used to abut against the side wall of the positioning groove of the memory piece to generate resistance, which prevents the memory piece in the storage cartridge from passing through the memory piece inlet selection ring and leaving the storage cartridge due to its own gravity;

[0044] When the positioning groove of the memory plate located on the side of the memory plate inlet selection ring facing away from the storage tube is axially aligned with the positioning protrusion of the memory plate inlet selection ring, the axial thrust block can overcome the resistance generated by the abutment between the flexible part and the side wall of the positioning groove of the memory plate, thereby allowing the memory plate to pass through the memory plate inlet selection ring and enter the storage tube.

[0045] In some possible embodiments, a position mark is provided on the side of the axial thrust block, and a marking window matching the position mark is provided on the end support cylinder. When the axial thrust block is rotated to the target angle, the position mark is visible in the marking window.

[0046] In some possible embodiments, the cylindrical housing further includes a covering component;

[0047] The storage cartridge is provided with a visual window on the side wall, through which the target memory mark on the memory piece contained in the storage cartridge can be observed, and the covering component is used to cover at least a portion of the visual window;

[0048] Preferably, the covering member is detachable or movable.

[0049] The present invention provides a memory training device in which a user can recall a memory marker on a memory piece in a storage cartridge, rotate the memory piece outlet selection ring to match the indicated memory marker with a target memory marker on the memory piece, and thereby remove the memory piece from the storage cartridge. In this manner, the memory training device provided in the present invention can train the user to memorize the memory marker on the memory piece by removing the memory piece, thereby training the user's ability to actively recall.

[0076] It should also be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0077] As shown in FIG1 , an embodiment of the present application provides a memory training device comprising: a cylindrical housing 1 and a plurality of memory discs 2. The cylindrical housing 1 includes a storage barrel 3 and a memory disc outlet selection ring 4, which are axially connected to each other and rotatable relative to each other about an axis. The storage barrel 3 is used to internally accommodate the plurality of memory discs and enable the memory discs to move axially along the storage barrel 3. The storage barrel 3 is provided with a memory disc inlet at a first axial end and is connected to the first end of the memory disc outlet selection ring 4 at a second end opposite the first end.

[0078] In an embodiment of the present application, the memory piece outlet selection ring 4 is provided with a memory piece outlet 5 at the second end opposite to the first end thereof; different memory marks are arranged in sequence along the circumferential direction on the edge of the memory piece, and different memory marks are arranged in sequence along the circumferential direction on the outer surface of the cylindrical shell 1; the memory piece outlet selection ring 4 is rotated to different angles relative to the storage barrel 3 to indicate different memory marks set on the cylindrical shell 1 respectively. When the memory piece outlet selection ring 4 is rotated so that the memory mark indicated by it matches the target memory mark on the target memory piece, the target memory piece can pass through the second end of the storage barrel 3, enter the memory piece outlet selection ring 4 and leave the memory piece outlet 5, wherein the target memory piece is the memory piece 2 in the storage barrel 3 that is closest to the memory piece outlet 5.

[0079] As can be seen, the memory training device provided by the embodiment of the present application allows the user to recall the memory mark on the memory piece in the storage cartridge, rotate the memory piece outlet selection ring so that the memory mark indicated matches the target memory mark on the memory piece, and then remove the memory piece from the storage cartridge. In this way, when using the memory training device provided by the embodiment of the present application, the user can train the ability of active recall by memorizing and recalling the memory mark on the memory piece.

[0080] As a possible embodiment, one of the memory disc 2 and the memory disc outlet selection ring 4 is provided with an axially extending and radially opening positioning groove, and the other is provided with a positioning protrusion that matches the positioning groove. As an example, the memory disc 2 shown in Figure 2 is provided with an axially extending and radially opening positioning groove (6a and 6b). The memory disc outlet selection ring 4 shown in Figure 3 is provided with positioning protrusions (7a and 7b) that match the positioning groove (6a and 6b). When the memory disc outlet selection ring 4 is rotated so that the memory mark indicated by it matches the target memory mark on the target disc, the positioning protrusions (7a and 7b) can pass through the positioning groove, thereby allowing the target disc passing through the second end of the storage tube 3 to enter the memory disc outlet selection ring 4 and exit from the memory disc outlet 5. In this embodiment of the present application, when the memory disc outlet selection ring 4 is rotated so that the memory mark indicated by it does not match the target memory mark on the target disc, the positioning protrusions (7a and 7b) block the target disc from exiting from the memory disc outlet 5. As a possible embodiment, the cylindrical housing in this embodiment of the present application also includes an alternating blocking member 8. 4 , an alternating blocking member 8 can be provided at the second end of the storage cartridge 3 . The alternating blocking member 8 switches between at least two blocking positions for selectively blocking the corresponding memory disc from passing through the second end of the storage cartridge 3 into the memory disc outlet selection ring 4 .

[0081] As a possible embodiment, the alternating blocking member 8 switches between a first blocking position and a second blocking position, and the plurality of memory chips 2 may include a first type memory chip 201 as shown in FIG5 and a second type memory chip 202 as shown in FIG6. It should be noted that when the alternating blocking member is in the first blocking position, it can block the first type memory chip 201 from passing through the second end of the storage barrel 3 and entering the memory chip outlet selection ring 4, while allowing the second type memory chip 202 to pass through the second end of the storage barrel 3 and enter the memory chip outlet selection ring 4. When the alternating blocking member 4 is in the second blocking position, it can block the second type memory chip 202 from passing through the second end of the storage barrel 3 and entering the memory chip outlet selection ring 4, while allowing the first type memory chip 201 to pass through the second end of the storage barrel 3 and enter the memory chip outlet selection ring 4.

[0082] As a possible embodiment, the alternating blocking member 8 is annular, sleeved over the second end of the storage cartridge 3, and rotatable relative to the second end of the storage cartridge 3 between a first blocking position and a second blocking position. At least one blocking protrusion 9 extending radially inward is provided on the inner wall of the alternating blocking member 8. The edge of the first-type memory sheet 201 is provided with a circumferentially continuous and radially open first alternating grooves 1001, the same number as the different memory markings. The edge of the second-type memory sheet 202 is provided with a circumferentially continuous and radially open second alternating grooves 1002, the same number as the different memory markings. The blocking protrusions are sized to pass through the first and second alternating grooves 1001, 1002.

[0083] When the alternating blocking member 8 is in the first blocking position, the blocking protrusions 9 are offset from the corresponding first alternating grooves 1001 and aligned with the corresponding second alternating grooves 1002. When the alternating blocking member 8 is in the second blocking position, the blocking protrusions 9 are offset from the corresponding second alternating grooves 1002 and aligned with the corresponding first alternating grooves 1001. Preferably, the memory plate outlet selection ring 4 is sleeved and connected to the alternating blocking member 8 and is rotatable relative to the alternating blocking member 8.

[0084] The first memory sheet 201 and the second memory sheet 202 are both provided with memory marks that match the memory marks on the cylindrical shell. As an example, the memory marks on the cylindrical shell can match the memory marks on the first memory sheet 201 and the second memory sheet 202, and the memory marks on the cylindrical shell are arranged in an order opposite to the order of the memory marks (1101 and 1102) on the memory sheet along the circumferential direction. As a possible embodiment, the different memory marks (1101 and 1102) provided on the cylindrical shell 1 can be located on the outer side of the alternating blocking member 8. The different memory marks provided on the cylindrical shell 1 can also be provided on the storage tube 3 or other components of the cylindrical shell, and the embodiments of the present application are not limited thereto.

[0085] The storage tube 3 shown in Figure 7 is provided with a visual window 12 on the side wall, through which the target memory mark among the multiple memory marks on the memory piece 2 contained in the storage tube 3 can be observed. In an embodiment of the present application, the target memory mark can be a user-visible memory mark among the multiple memory marks on the memory piece 2, such as a memory mark exposed in the visual window 12. In an embodiment of the present application, the cylindrical shell 1 may further include a covering component 17 as shown in Figure 8. The covering component 17 is used to cover at least a partial area of ​​the visual window 12. Preferably, the covering component is detachable or movable. As a possible embodiment, at least one guide rail 15 is provided on the inner wall of the storage tube 3 for passing through the corresponding sliding grooves and / or positioning grooves provided on the memory piece, so that the memory piece can move axially along the storage tube 3.

[0086] It should be noted that the user can first open the cover member 17 to observe the target memory mark on the memory chip 2 contained in the storage cartridge 3, and then close the cover member 17 to cover the memory mark on the memory chip in the visible window 12. The user can then rotate the memory chip outlet selection ring 4 according to the target memory mark on the target memory chip closest to the memory chip outlet selection ring 4. When the memory mark indicated by the memory chip outlet selection ring 4 matches the target memory mark on the target memory chip, the target memory chip can pass through the second end of the storage cartridge 3, enter the memory chip outlet selection ring 4, and exit from the memory chip outlet 5. In this embodiment of the present application, the memory chip outlet 5 at the second end of the storage cartridge 3 may also be provided with a cover plate 16 as shown in Figure 9.

[0087] As an example, when the memory chip outlet selection ring 4 is rotated so that the memory mark 1101 indicated by it matches the target memory mark 1101 on the target memory chip, the target memory chip can pass through the second end of the storage tube 3 into the memory chip outlet selection ring 4 and exit from the memory chip outlet 5.

[0088] As a possible implementation, when the memory chip outlet selection ring 4 is rotated so that the memory mark indicated by it does not match the target memory mark on the target memory chip, the target memory chip can only partially enter the memory chip outlet selection ring 4, and is thereby stuck at the first end of the memory chip outlet selection ring 4 and cannot leave the memory chip outlet 5.

[0089] As an example, the positioning protrusion 7a includes a laterally reduced protrusion extension on the side facing the positioning grooves (6a and 6b), and at least one sliding groove is provided on one of the memory plate 2 and the memory plate outlet selection ring 4, which allows the protrusion extension to enter but does not allow the positioning protrusions (7a and 7b) to enter as a whole. As a possible embodiment, the memory plate outlet selection ring 4 shown in Figure 3 can be provided with a laterally reduced protrusion extension 13 on the side of the positioning protrusion 7a facing the positioning groove. The memory plate shown in Figure 2 includes a positioning protrusion sliding groove 14, and the sliding groove 14 only allows the protrusion extension to enter but does not allow the positioning protrusions (7a and 7b) to enter as a whole. Moreover, the radial opening depth of the positioning groove 6b in this application is less than the opening depth of the positioning groove 7b, but the opening depth of the positioning groove 6b is greater than the radial height of the protrusion extension 13. Therefore, when the memory plate outlet selection ring 4 is rotated so that the memory mark indicated by it does not match the target memory mark on the target memory plate, only the protruding extension 13 enters the sliding groove 14 or the positioning groove 6b at the corresponding position to form a jam.

[0090] As another example, a first sliding groove and at least one second sliding groove are provided on one of the memory piece and the memory piece outlet selection ring 4, and a stepped protrusion is provided on the other of the memory piece and the memory piece outlet selection ring 4. The size of the stepped protrusion is such that it can enter the first sliding groove as a whole but can only partially enter the second sliding groove. When the memory piece outlet selection ring 4 is rotated so that the memory mark indicated by it matches the target memory mark on the target memory piece, the stepped protrusion enters the first sliding groove as a whole, thereby allowing the memory piece to enter the memory piece outlet selection ring 4 and exit from the memory piece outlet 5; when the memory piece outlet selection ring 4 is rotated so that the memory mark indicated by it does not match the target memory mark on the target memory piece, the stepped protrusion partially enters the second sliding groove and becomes stuck.

[0091] As shown in Figure 10a, the cover plate 16, the memory piece outlet selection ring 4, the alternating blocking member 8, the covering component 17, the storage cylinder 3 and the memory piece 2 can constitute the memory piece outlet structure of the memory training device provided in the embodiment of this application. The inlet structure of the memory training device provided in the embodiment of this application is introduced below.

[0092] In the embodiment of the present application, the cover plate 16 and the memory chip outlet selection ring 4 can be connected by means of snaps, bolts, or magnetism, which is not limited in the embodiment of the present application. As an example, when the cover plate 16 and the memory chip outlet selection ring 4 are connected by magnetism, the cover plate 16 can be provided with a magnet inside, and the memory chip outlet selection ring 4 can be provided with an iron sheet corresponding to the magnet inside.

[0093] In an embodiment of the present application, as shown in Figure 10b , the storage cartridge 3 may further include a memory chip inlet 27. This inlet is used to insert a memory chip removed from the memory chip outlet by the user for reuse. The cylindrical housing 1 may further include an end support cylinder 18 . This end support cylinder 18 is axially disposed at the first end of the storage cartridge 3 . This end support cylinder 18 is configured to accommodate an axial thrust block 19 , as shown in Figure 12 , within the end support cylinder 18 . This axial thrust block 19 is axially movable relative to the end support cylinder 18 .

[0094] As a possible embodiment, an elastic member may be provided between the end support tube 18 and the axial thrust block 19 to apply elastic force to the axial thrust block 19, causing the axial thrust block 19 to axially press against the memory piece 2 in the storage tube 3. The axial thrust block may be provided with a pulling protrusion extending through the end support tube; alternatively, a sliding groove may be provided on the side wall of the end support tube for the pulling protrusion to move axially therein.

[0095] As another possible embodiment, as shown in FIG14 , the axial thrust block 19 is provided with a handle 21 that passes through the end of the terminal support tube 18. The handle 21 is used for the user to pull to cause the axial thrust block 19 to move axially within the terminal support tube 18. In actual application, the handle 21 may also be equipped with an end decorative piece 22 as shown in FIG15 at the end opposite the terminal support tube 18.

[0096] Preferably, as shown in FIG18 , the storage cylinder 3 is provided with a first guide rail 301 and a second guide rail 302 in sequence along the axial direction. The first guide rail 301 and the second guide rail 302 are collinear, and the second guide rail 302 is wider than the first guide rail 301. The axial thrust block 19 is coaxial with the end support cylinder 18. As shown in FIG11 , the outer surface of the end support cylinder 18 is provided with a first groove 1801 and a second groove 1802.

[0097] When the user pulls handle 21, first groove 1801 slides along first guide rail 301. When axial thrust block 19 and end support cylinder 18 are pulled to the bottom, second guide rail 302 abuts against first groove 1801. A sliding gap 303 is provided between first guide rail 301 and second guide rail 302. When axial thrust block 19 and end support cylinder 18 are pulled to the bottom, sliding gap 303 allows end support cylinder 18 to rotate circumferentially relative to storage cylinder 3. As shown in FIG11 , second groove 1802 is axially connected to first groove 1801, and the second groove is wider than the first groove. When end support cylinder 18 rotates axially relative to storage cylinder 3, second guide rail rotates within the second groove. The first groove and first guide rail are offset, causing end support cylinder 18 to be locked in the axial direction, while axial thrust block 19 and end support cylinder 18 can rotate relative to each other.

[0098] It should be noted that when the user pulls the handle 21, the axial thrust block 19 and the end support tube 18 are pulled to the bottom. The user can then rotate the end support tube 18 circumferentially relative to the storage tube 3, causing the end support tube 18 to be locked axially. The user can then insert a memory chip into the storage tube 3 through the memory chip inlet 27. Preferably, a bearing 23, as shown in Figure 13, can be provided between the axial thrust block 19 and the end support tube 18 to assist in the relative rotation between the axial thrust block 19 and the end support tube 18.

[0099] In the embodiment of the present application, the end of the axial thrust block 19 close to the memory plate is in anti-rotational cooperation with the central part 20 of the memory plate; the axial thrust block 19 can rotate circumferentially relative to the storage tube 3, so that the end of the axial thrust block 19 close to the memory plate enters into anti-rotation cooperation with the central part 20 of the memory plate.

[0100] The memory training device may also include a memory piece entrance selection ring 24 as shown in Figure 16, which is arranged in a circumferential sliding track formed on the inner wall of the second end of the storage tube 3, and can rotate circumferentially relative to the storage tube 3 around the axis; the memory piece entrance selection ring 24 radially forms a positioning protrusion (7c and 7d) that matches the positioning groove on the memory piece, and the memory piece can pass through the memory piece entrance selection ring 24 into the storage tube 3 when the positioning groove (6a and 6b) is aligned with the positioning protrusion (7c and 7d).

[0101] As a possible embodiment, as shown in FIG16 , the positioning protrusions (7c and 7d) of the memory disc inlet selection ring 24 at least partially extend a flexible portion made of a flexible material. When the positioning groove of a memory disc adjacent to the memory disc inlet selection ring 24 in the storage cartridge is axially aligned with the positioning protrusions (7c and 7d) of the memory disc inlet selection ring 24, the flexible portion is configured to abut against the sidewalls of the positioning groove of the memory disc to generate resistance. This resistance can prevent the memory disc in the storage cartridge from passing through the memory disc inlet selection ring 24 under its own weight and leaving the storage cartridge. When the positioning groove of the memory disc located on the side of the memory disc inlet selection ring 24 facing away from the storage cartridge is axially aligned with the positioning protrusions (7c and 7d) of the memory disc inlet selection ring 24, the axial thrust block can overcome the resistance generated by the abutment of the flexible portion against the sidewalls of the positioning groove of the memory disc, thereby allowing the memory disc to pass through the memory disc inlet selection ring 24 and enter the storage cartridge.

[0102] As a possible embodiment, in the embodiment of the present application, the central portion of the positioning protrusions (7c and 7d) of the memory plate inlet selection ring 24 can be made of a hard material, and the edge portion of the positioning protrusions (7c and 7d) of the memory plate inlet selection ring 24 can be made of a flexible material. When the edge portion of the positioning protrusions (7c and 7d) of the memory plate inlet selection ring 24 is made of a flexible material, the area of ​​the central portion of (7c and 7d) in the circumferential plane is smaller than the area of ​​the positioning grooves (6a and 6b) in the circumferential plane. The area of ​​the positioning protrusions (7c and 7d) including the edge portion in the circumferential plane is larger than the area of ​​the positioning grooves (6a and 6b) in the circumferential plane. When the memory plate rotates relative to the memory plate inlet selection ring so that the positioning grooves (6a and 6b) are aligned with the positioning protrusions (7c and 7d), the flexible material of the edge portion of the positioning protrusions (7c and 7d) of the memory plate inlet selection ring 24 is compressed under the action of the axial force, thereby allowing the memory plate to pass through the positioning groove. After the target memory chip passes through the positioning groove, the flexible material of the positioning protrusion edge portion of the memory chip inlet selection ring 24 prevents the memory chip from passing through the positioning groove in the reverse direction.

[0103] An axial protrusion 25 is provided on the side of the memory piece inlet selection ring 24 facing the memory piece outlet 5, and a slope is provided on the side wall of the sliding track facing the axial protrusion. When the memory piece inlet selection ring 24 rotates relative to the storage cylinder 3 along a first circumferential direction, the axial protrusion 25 repeats the process of climbing and falling on the slope. When the memory piece inlet selection ring 24 rotates relative to the storage cylinder 3 along a second circumferential direction opposite to the first circumferential direction, the axial protrusion 25 is stuck by the slope.

[0104] As a possible embodiment, as shown in FIG12 , a position mark 1901 is provided on the side of the axial thrust block 19 , and as shown in FIG10 b , the storage cylinder 3 is provided with a marking window 26 that matches the position mark 1901 . When the axial thrust block 19 is rotated to the target angle, the position mark 1901 is visible in the marking window 26 .

[0105] It can be seen that, as shown in Figure 17, the storage cylinder 3, the memory piece 2, the memory piece inlet selection ring 24, the axial thrust block 19, the bearing 23, the end support cylinder 18, the handle 21 and the end decorative piece 22 can constitute the memory piece inlet structure of the memory training device provided in the embodiment of this application.

[0106] In actual use, after inserting a memory chip, the user can use handle 21 to rotate the axial thrust block 19 relative to the end support cylinder 18, causing the position mark 1901 to change direction. The user can then rotate the end support cylinder 18 relative to the storage cylinder 3, realigning the first groove 1801 on the end support cylinder 18 with the first guide rail 301 on the storage cylinder 3. This allows the storage cylinder to slide axially along the first guide rail toward the memory chip, causing the end of the axial thrust block 19 closest to the memory chip to abut against the central portion 20 of the memory chip. Because the end of the axial thrust block 19 closest to the memory chip is anti-rotationally engaged with the central portion 20 of the memory chip, the user can then rotate the axial thrust block 19 in the first circumferential direction using handle 21, causing the newly inserted memory chip to rotate along the first circumferential direction. Due to friction, the newly inserted memory chip also rotates the memory chip entry selector ring 24 along the first circumferential direction, causing the axial protrusion 25 on the entry selector ring 24 to repeatedly climb and fall along the slope.

[0107] As an example, the user can directly rotate the axial thrust block 19 to any angle. As another example, if the user has previously used the handle 21 to relatively rotate the axial thrust block 19 and the end support cylinder 18 so that the position mark 1901 changes direction, the user can also rotate the axial thrust block 19 to the target angle so that the position mark 1901 is visible in the mark window 26, thereby rotating the axial thrust block 19 to an undetermined angle and thus placing the inlet selection ring 24 in an undetermined direction.

[0108] Then, the user can rotate the axial thrust block 19 along the second circumferential direction using the handle 21. After the inlet selection ring 24 is driven to rotate along the second circumferential direction by a certain angle, the axial protrusion 25 is caught by the slope. The user can continue to rotate the axial thrust block 19 along the second circumferential direction using the handle 21. The newly inserted memory disc can then rotate relative to the inlet selection ring 24 along the second circumferential direction until the memory disc rotates relative to the memory disc inlet selection ring so that the positioning grooves (6a and 6b) and the positioning protrusions (7a and 7b) are aligned. The newly inserted memory disc can then pass through the memory disc inlet selection ring 24 and enter the storage cartridge 3. It should be noted that the above-mentioned device arrangement of the present application can make the inlet selection ring 24 be in a random direction, so that the memory mark displayed in the visual window 12 of the memory disc aligned with the inlet selection ring 24 is also random.

[0109] In summary, the embodiment of the present application provides a memory training device, in which the user can recall the memory mark of the memory piece in the storage tube, rotate the memory piece outlet selection ring so that the memory mark indicated by it matches the target memory mark on the memory piece, and thus remove the memory piece from the storage tube. In this way, the memory training device provided by the embodiment of the present application can train the ability of active recall by means of memorizing and recalling the memory marks on the memory piece. In addition, through the memory piece inlet structure of the memory training device provided by the present application, the user can display a random memory mark in the visual window of the inserted memory piece, which is convenient for the user to replenish the memory piece with a random memory mark in the storage tube, so that the user can recycle the memory pieces in the memory training device provided by the present application for memory training.
