[0001] Cross-references to related applications
[0002] This application claims priority to Chinese Patent Application No. 202510386747.3, filed on March 27, 2025, entitled "A Memory", the entire contents of which are incorporated herein by reference. Technical Field
[0003] This application relates to the field of storage device technology, and more particularly to a memory. Background Technology
[0004] The development of information technology has placed higher demands on storage media. Compared with traditional semiconductor storage technology, magnetic memory with magnetic tunnel junction (MTJ) as storage unit has the advantages of high storage capacity, low cost and long and stable data retention time.
[0005] In magnetic storage devices (MSDs), the magnetic tape is wound onto a reel, which rotates under the drive of a motor. This rotation causes relative movement between the magnetic tape and the magnetic head, allowing the head to sequentially record or read data from the tape. In related technologies, to improve the reliability of MSDs, many complex structures are incorporated, such as locking mechanisms to prevent tape damage, breakage, or tangling, or cleaning structures for cleaning the magnetic heads. These structures often occupy excessive internal space, compressing the tape length and hindering the design of large-capacity MSDs. Summary of the Invention
[0006] This application provides a memory to improve the operational reliability and storage capacity of the memory.
[0007] In a first aspect, this application provides a memory, which includes a housing, a magnetic tape, a reel, and a magnetic head. A handle is provided at one end of the housing, which can be embedded in the housing in a non-use state and extended from the housing in a use state, allowing the user to remove the memory from the electronic device via the handle. The magnetic tape, the reel, and the magnetic head are disposed within the housing; the magnetic tape is wound on the reel, and the magnetic head is used to read and write data on the magnetic tape. The memory also includes a reel locking mechanism, a handle locking mechanism, a head cleaning mechanism, and a drive mechanism disposed in the housing. The reel locking mechanism has a reel locked state and a reel unlocked state, and can be used to lock the reel in the locked state and unlock the reel in the unlocked state. The handle locking mechanism has a handle locking state and a handle unlocked state, and can be used to lock the handle within the housing in the locked state and unlock the handle in the unlocked state. The head cleaning mechanism's cleaning brush can switch between a first position and a second position within the housing. The cleaning brush is used to clean the head in the first position and away from the head in the second position. The drive mechanism is used to drive the reel locking mechanism to switch from the reel locked state to the reel unlocked state during a first drive stroke, and to drive the handle locking mechanism to switch from the handle unlocked state to the handle locked state, and to drive the cleaning brush to lock in the second position.
[0008] In this application, the drive mechanism, during the first drive stroke, drives the reel locking mechanism to switch from a reel locked state to a reel unlocked state, and drives the handle locking mechanism to switch from a handle unlocked state to a handle locked state. It also locks the cleaning brush in a second position. Thus, during normal operation, the cleaning brush can be positioned away from the magnetic head, the reel can move the magnetic tape relative to the magnetic head under the drive of the winding motor, and the handle can be locked inside the housing, thereby improving the reliability of the memory. Furthermore, since the memory can control the reel locking mechanism, handle locking mechanism, and magnetic head cleaning mechanism through a single drive mechanism, the structural and installation space required to implement the reel locking, handle locking, and magnetic head cleaning functions can be reduced, allowing the memory to provide more space for the magnetic tape, thereby contributing to an increase in storage capacity.
[0009] In some implementations, the drive mechanism can also be used to drive the reel locking mechanism to remain in the unlocked state during the second drive stroke, drive the handle locking mechanism to remain in the locked state, and drive the cleaning brush to move from the second position to the first position, enabling the cleaning brush to clean the magnetic head in the first position. Additionally, in this application scenario, the continued locking of the handle prevents the memory from being suddenly pulled out of the electronic device by the user during cleaning, reducing the risk of tape damage.
[0010] In some implementations, the drive mechanism may include a motor, a worm gear, and a turbine. The worm gear is fixedly connected to the output shaft of the motor and can rotate synchronously under the drive of the motor. The turbine meshes with the worm gear so that it can also rotate synchronously with the worm gear. The turbine is driven by a reel locking mechanism, a handle locking mechanism, and a magnetic head cleaning mechanism, respectively. In this way, the turbine can drive the reel locking mechanism, the handle locking mechanism, and the magnetic head cleaning mechanism to switch or maintain their states during rotation.
[0011] For example, the rotation axis of the worm and the rotation axis of the turbine can be orthogonal to reduce the size of the drive mechanism, thereby reducing the space occupied by the drive mechanism in the housing.
[0012] In some implementations, the drive mechanism includes a first drive rod, which is pultrusively connected to the reel locking mechanism, and the first drive rod is provided with a first sliding column. The turbine shaft includes a first end, and the circumferential surface of the turbine shaft is provided with a first sliding groove and a second sliding groove. The first and second sliding grooves extend circumferentially along the turbine shaft, and the first and second sliding grooves communicate with each other. The distance between the first sliding groove and the first end is different from the distance between the second sliding groove and the first end. During the first drive stroke of the drive mechanism, the motor drives the turbine to rotate, which in turn drives the first sliding column to slide from the first sliding groove to the second sliding groove, thereby causing a change in the overall position of the first drive rod. By utilizing the change in the position of the first drive rod, the reel locking mechanism can be switched from the reel locked state to the reel unlocked state.
[0013] In some implementations, during the second drive stroke of the drive mechanism, the motor drives the turbine to rotate, and the turbine can drive the first slide column to slide in the second slide groove. Since the positions of all parts of the second slide groove are at the same height of the turbine shaft, the overall position of the first drive rod does not change, thereby driving the reel locking mechanism to remain in the reel unlocked state.
[0014] In some embodiments, the first and second slides can be connected by a first connecting groove, which is inclined relative to the end face of the first end of the turbine shaft. Furthermore, at the connection point between the first connecting groove and the first slide, the walls of the first connecting groove and the first slide are connected by curved surfaces to achieve a smooth transition between them; similarly, at the connection point between the second connecting groove and the second slide, the walls of the first connecting groove and the second slide are also connected by curved surfaces to achieve a smooth transition between them. This design not only reduces the risk of the first sliding column getting stuck between the first and second connecting grooves but also allows the first sliding column to slide relatively smoothly from the first slide to the second slide, thereby improving the driving smoothness of the reel locking mechanism.
[0015] In some embodiments, the drive mechanism further includes a second drive rod, which is connected to the magnetic head cleaning mechanism and has a second sliding column. The turbine shaft includes a first end, and a third and fourth sliding groove are provided on the circumferential surface of the turbine shaft. The third and fourth sliding grooves extend circumferentially along the turbine shaft and are connected. The distances between the third and fourth sliding grooves and the first end are different. During the first drive stroke of the drive mechanism, the motor drives the turbine to rotate, which in turn drives the second sliding column to slide within the third sliding groove. Since all positions of the third sliding groove are at the same height of the turbine shaft, the overall position of the second drive rod does not change, thereby driving the cleaning brush to remain in the second position.
[0016] In some implementations, during the second drive stroke of the drive mechanism, the motor drives the turbine to rotate, and the turbine can drive the second slide column to slide from the third slide groove to the fourth slide groove, thereby causing the overall position of the second drive rod to change. By utilizing the position change of the second drive rod, the cleaning brush can be driven to switch from the second position to the first position, so that the cleaning brush can clean the magnetic head.
[0017] In some implementations, the drive mechanism further includes a connecting shaft and a third drive rod. The connecting shaft is connected to one axial end of the turbine, and the end face of the connecting shaft opposite to the turbine includes an eccentrically positioned third sliding column. As the connecting shaft rotates with the turbine, the third sliding column can perform circular motion. The third drive rod is located on the side of the connecting shaft opposite to the turbine and has a fifth sliding groove. The fifth sliding groove includes a first sub-groove and a second sub-groove that are connected. The extension direction of the first sub-groove is perpendicular to the extension direction of the third drive rod, and the second sub-groove is an arc-shaped groove. During the first drive stroke of the drive mechanism, the motor drives the turbine to rotate, and the turbine can drive the third sliding column to slide within the first sub-groove. Because the third sliding column performs circular motion, and the first sub-groove is a straight groove, the position of the third drive rod changes when the third sliding column moves. This change in the position of the third drive rod can be used to switch the handle bar locking mechanism from the handle bar unlocked state to the handle bar locked state.
[0018] In some implementations, during the second drive stroke of the drive mechanism, the motor drives the turbine to rotate, and the turbine can drive the third slide column to slide in the second sub-slot. Since the second sub-slot is an arc-shaped slot, and the shape of the second sub-slot is approximately the same as the movement path of the third slide column, the position of the third drive rod will not change significantly. Therefore, the handle bar locking mechanism can be driven to remain in the handle bar locked state.
[0019] In some implementations, the distance between the center of the third sliding column and the center of the connecting column can be equal to the radius of the second sub-slot. That is, the movement radius of the third sliding column is equal to the radius of the second sub-slot. Thus, during the sliding of the third sliding column in the second sub-slot, the position of the third drive rod can be kept in the same position, so that the handle bar locking mechanism can be reliably kept in the handle bar locking state.

Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. The same reference numerals in the figures denote the same or similar structures, and therefore repeated descriptions of them will be omitted. The terms expressing position and direction described in the embodiments of this application are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this application. The accompanying drawings of the embodiments of this application are only for illustrating relative positional relationships and do not represent actual scale.
[0035] It should be noted that specific details are set forth in the following description to facilitate understanding of this application. However, the embodiments of this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the embodiments of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0036] Magnetic storage devices enable large-capacity data storage and high-speed data retrieval. A typical magnetic storage device consists of magnetic tape, a reel, and a magnetic head. The magnetic tape is wound on the reel, which rotates under the drive of a motor, thus moving the tape relative to the magnetic head. The magnetic head sequentially records or retrieves data from the tape via electromagnetic conversion. However, because the tape rotates freely when the motor is de-energized, it is prone to breakage or tangling.
[0037] Magnetic storage devices (MSDs) can be plugged into the chassis of electronic devices. These MSDs are typically equipped with a handle, which is usually embedded in the casing. To remove the MSD from the device, the handle must be unlocked after the MSD has stopped operating, allowing it to pop out of the casing for easy removal. If the MSD is suddenly pulled out of the device while it is in operation, the system may not be able to stop the motor driving the tape reel in time, potentially damaging the magnetic tape.
[0038] In addition, since the surface of the magnetic tape is coated with magnetic powder, the magnetic powder may wear off and fall off when the tape and the magnetic head move relative to each other. Over time, the magnetic powder will accumulate on the surface of the magnetic head, causing a decrease in magnetic flux, affecting the reading and writing accuracy of the magnetic head, increasing the bit error rate, and in severe cases, even making reading and writing impossible.
[0039] In related technologies, in order to improve the working reliability of magnetic storage devices, many complex structures are often set in the magnetic storage device, such as locking structures to prevent the magnetic tape from being damaged, broken or tangled, or cleaning structures for cleaning the magnetic head. These structures often occupy too much internal space of the magnetic storage device, thereby compressing the length of the magnetic tape and affecting the large-capacity design of the magnetic storage device.
[0040] In view of this, embodiments of this application provide a memory that can control the reel locking, handle locking, and magnetic head cleaning functions through a set of drive mechanisms. This memory has a simple structure and requires relatively little installation space, thereby improving its operational reliability and storage capacity. The magnetic memory will be further described in detail below with reference to specific embodiments.
[0041] Figure 1 is a schematic diagram of the structure of the memory 1000 provided in an embodiment of this application. Referring to Figure 1, the memory 1000 provided in this embodiment can be applied to various electronic devices to store various data and programs in the electronic device. The electronic device is provided with a frame, and the memory 1000 can be inserted into the frame and electrically connected to the internal components of the electronic device through a connector, so that the electronic device can record or read data in the memory 1000.
[0042] For example, electronic devices may be, but are not limited to, information and communications technology (ICT) devices, computing devices (such as servers), artificial intelligence computing clusters, terminal devices (such as laptops or desktops), or storage devices (such as storage arrays).
[0043] In this embodiment, the memory 1000 includes a housing 100, a magnetic tape 200, a reel 300, and a magnetic head 400. The housing 100 can be used to house the magnetic tape 200, the reel 300, the magnetic head 400, and other structures. The housing 100 has a first end 100a disposed opposite to the second end 100a, which is provided with a connector (not shown) for electrical connection with an electronic device. After the memory 1000 is assembled into the electronic device, the first end 100a of the housing 100 is inserted into a mounting frame, while the second end 100b of the housing 100 is exposed outside the mounting frame. The second end 100b of the housing 100 is provided with a handle 500. The handle 500 can be embedded in the housing 100 when not in use to reduce the risk of accidental contact or collision during transportation or use of the memory 1000. When in use, the handle 500 can extend from the housing 100, allowing the user to remove the memory 1000 from the mounting frame using the handle 500.
[0044] There are two reels 300, which are arranged side by side and rotatably connected to the housing 100. The two reels are defined as the first reel 300a and the second reel 300b. The magnetic tape 200 is wound on the first reel 300a and the second reel 300b. When the first reel 300a and the second reel 300b rotate synchronously, the magnetic tape 200 can be released from the first reel 300a and wound onto the second reel 300b, or released from the second reel 300b and wound onto the first reel 300a.
[0045] A magnetic head 400 can be disposed between a first reel 300a and a second reel 300b, and the magnetic head 400 is positioned toward the magnetic tape 200 between the first reel 300a and the second reel 300b. During the process of the magnetic tape 200 being wound from one reel 300 to another, the magnetic tape 200 moves relative to the magnetic head 400, and the magnetic head 400 can sequentially write data into or read data from the magnetic tape 200. For example, during the process of the magnetic tape 200 being wound from the first reel 300a to the second reel 300b, the magnetic head can sequentially write data into the magnetic tape 200; during the process of the magnetic tape 200 being wound from the second reel 300b to the first reel 300a, the magnetic head can sequentially read data from the magnetic tape 200.
[0046] In some embodiments, the memory 1000 further includes a winding motor 310 corresponding to each of the tape reels 300. The winding motor 310 can drive the tape reels 300 to rotate, thereby causing the magnetic tape 200 to move relative to the magnetic head 400. When writing or reading data, the two tape reels 300 can rotate in the same direction or in opposite directions under the drive of the corresponding winding motor 310. The specific design can be based on the winding method of the magnetic tape 200 on the two tape reels 300, which is not limited in this application.
[0047] Please continue to refer to Figure 1. The memory 1000 also includes a reel locking mechanism 600, a handle locking mechanism 700, a head cleaning mechanism 800, and a drive mechanism 900. The drive mechanism 900 can adjust the working state of the reel locking mechanism 600, the handle locking mechanism 700, and the head cleaning mechanism 800, thereby controlling the locking of the reel 300, the locking of the handle 500, and the cleaning of the head 400 in a time-sequence manner.
[0048] The reel locking mechanism 600 includes a reel locked state and a reel unlocked state. The reel locking mechanism 600 can be used to lock the reel 300 in the locked state and to unlock the reel 300 in the unlocked state. The reel locking mechanism 600 can be disposed between two reels 300 to control the two reels 300, facilitating simultaneous locking or unlocking of both reels 300, thereby enabling the two reels 300 to stop or rotate synchronously. For example, the reel locking mechanism 600 may include a clamping structure, which can clamp and position the reel in its locked state to achieve the locking function; alternatively, the reel locking mechanism 600 may also include a friction plate structure, which can be fixed to the reel through friction in its locked state to achieve its locking function. This application does not limit the specific structure and implementation of the tape reel locking mechanism 600, as long as it can achieve the locking and unlocking functions of the tape reel.
[0049] When the winding motor 310 is powered off, the reel locking mechanism 600 locks both reels 300. After the two reels 300 stop rotating synchronously, the magnetic tape 200 can maintain the same tension as during normal operation, thereby preventing the magnetic tape 200 from breaking or tangling due to the free rotation of the winding motor 310, and improving the reliability of the memory 1000. When the winding motor 310 is powered on, the reel locking mechanism 600 unlocks the two reels 300, allowing them to rotate under the drive of their respective winding motors 310.
[0050] The handle bar locking mechanism 700 includes a handle bar locked state and a handle bar unlocked state. The handle bar locking mechanism 700 can be used to lock the handle bar 500 within the housing 100 in the locked state, and can be used to unlock the handle bar 500 in the unlocked state. Exemplarily, the handle bar locking mechanism 700 may also include a latching structure, allowing it to engage and fix with the handle bar in its locked state to achieve the locking function of the handle bar.
[0051] During the transportation or use of the memory 1000, the handle locking mechanism 700 locks the handle 500 inside the housing 100 to reduce the risk of accidental contact or impact to the handle 500. When it is necessary to remove the memory 1000 from the electronic device's mounting frame, the handle locking mechanism 700 unlocks the handle 500, allowing it to extend from the housing 100 for easy pulling by the user.
[0052] The magnetic head cleaning mechanism 800 includes a cleaning brush 810, which can be switched between a first position A and a second position B within the housing 100. The first position A is located close to the magnetic head 400, and the second position B is located away from the magnetic head 400. The cleaning brush 810 can clean the magnetic head 400 in the first position A. When the magnetic head cleaning mechanism 800 adjusts its cleaning brush 810 to the first position A, it can use the cleaning brush 810 to clean the magnetic head 400. When the magnetic head cleaning mechanism 800 adjusts its cleaning brush 810 to the second position B, the cleaning brush 810 is located away from the magnetic head 400.
[0053] In one implementation, the first position A can be located on one side of the two reels 300 of the magnetic head 400. When the cleaning brush 810 moves to the first position A, the cleaning brush 810 or other support structure in the magnetic head cleaning mechanism 800 can lift the magnetic tape 200 away from the magnetic head 400, so that the cleaning brush 810 is located between the magnetic head 400 and the magnetic tape 200 to clean the magnetic head 400.
[0054] When the memory 1000 is not installed in an electronic device (e.g., in a transportation scenario or a scenario where it is to be used), the reel locking mechanism 600 is in the reel locking state, the handle locking mechanism 700 is in the handle locking state, and the cleaning brush 810 of the cleaning mechanism is locked in the second position B. This can prevent problems such as the reel 300 breaking or getting tangled and the handle 500 extending during transportation or other scenarios. After the memory 1000 is plugged into the electronic device, the drive mechanism 900 is used to drive the reel locking mechanism 600 from the reel locked state to the reel unlocked state during the first drive stroke, and to drive the handle locking mechanism 700 from the handle unlocked state to the handle locked state, and to drive the cleaning brush 810 to lock in the second position B. In this way, during normal operation, the memory 1000 can keep the cleaning brush 810 away from the magnetic head 400, and the reel 300, driven by the winding motor 310, can move the magnetic tape 200 relative to the magnetic head 400, while preventing the handle 500 from extending out of the housing 100, thereby improving the operational reliability of the memory 1000. The drive stroke of the drive mechanism can be understood as the movement stroke of the drive component in the drive mechanism. For example, when the drive component is a motor, the drive stroke of the drive component is the rotation stroke of the motor's output shaft.
[0055] Furthermore, since the memory 1000 can control the reel locking mechanism 600, the handle locking mechanism 700, and the head cleaning mechanism 800 through a set of drive mechanisms 900, the reel locking mechanism 600, the handle locking mechanism 700, and the head cleaning mechanism 800 can switch or maintain their states within the same drive stroke of the drive mechanism 900. In other words, the reel locking mechanism 600, the handle locking mechanism 700, and the head cleaning mechanism 800 are linked together through the drive mechanism 900, thus effectively reducing the difficulty of controlling the timing of each mechanism's actions. Moreover, compared to existing technologies, this embodiment can reduce the structural and installation space required to implement the functions of locking the reel 300, locking the handle 500, and cleaning the head 400, allowing the memory 1000 to provide more space for the magnetic tape 200, thereby helping to increase the storage capacity of the memory 1000.
[0056] In some embodiments, the drive mechanism 900 can also be used to drive the reel locking mechanism 600 to remain in the reel unlocked state during the second drive stroke, drive the handle locking mechanism 700 to remain in the handle locking state, and drive the cleaning brush 810 of the magnetic head cleaning mechanism 800 to move from the second position B to the first position A, so that the cleaning brush 810 can clean the magnetic head 400 at the first position A. In this scenario, the handle locking mechanism 700 remains in the locked state, which can prevent the memory 1000 from being suddenly pulled out of the electronic device by the user during the cleaning process, reducing the risk of damage to the magnetic tape 200.
[0057] For ease of description, in the following embodiments, the scenario in which the memory 1000 is not installed in an electronic device is defined as a non-working scenario, the scenario in which the memory 1000 is working normally is defined as a working scenario, and the scenario in which the magnetic head 400 is cleaned is defined as a cleaning scenario.
[0058] Figure 2 is a structural schematic diagram of the drive mechanism 900 provided in this embodiment of the application in a non-working scenario, and Figure 3 is a partial structural exploded view of the drive mechanism 900 provided in this embodiment of the application. Referring to Figures 2 and 3 together, in this embodiment of the application, the drive mechanism 900 includes a motor 910, a worm gear 920, and a turbine 930. The worm gear 920 is connected to the output shaft of the motor 910 to rotate synchronously under the drive of the motor 910. The turbine 930 meshes with the worm gear 920, so that the worm gear 920 can also drive the turbine 930 to rotate synchronously during rotation. The angle between the rotation axis of the worm gear 920 and the rotation axis of the turbine 930 is greater than 0 degrees and less than 180 degrees. Exemplarily, the rotation axis of the worm gear 920 and the rotation axis of the turbine 930 are orthogonal to reduce the size of the drive mechanism 900.
[0059] The turbine 930 is connected to the reel locking mechanism 600, the handle bar locking mechanism 700 and the magnetic head cleaning mechanism 800 respectively. The turbine 930 can drive the reel locking mechanism 600, the handle bar locking mechanism 700 and the magnetic head cleaning mechanism 800 to switch or maintain their states during rotation.
[0060] In this embodiment, the turbine 930 includes a turbine body 931 and a turbine shaft 932. The turbine body 931 meshes with the worm gear 920, and the turbine shaft 932 is connected to one axial end of the turbine body 931. The turbine body 931 and the turbine shaft 932 can be an integral structure, or they can be independently processed and then assembled and fixed. This application does not limit this.
[0061] Figure 4 is a schematic diagram of the turbine 930 of the drive mechanism provided in an embodiment of this application. Referring to Figures 3 and 4 together, the turbine shaft 932 includes a first end 932a arranged axially. Exemplarily, the first end 932a of the turbine shaft 932 can be the end of the turbine shaft 932 that is away from the turbine body 931. A first groove 9321 and a second groove 9322 are provided on the circumferential surface of the turbine shaft 932. The first groove 9321 and the second groove 9322 extend circumferentially along the turbine shaft 932, and the first groove 9321 communicates with the second groove 9322. The distance between the first groove 9321 and the first end 932a of the turbine shaft 932 is different from the distance between the second groove 9322 and the first end 932a of the turbine shaft 932. This can also be understood as taking the axial direction of the turbine shaft 932 as its height direction; the height of the first groove 9321 is the same at all points, and the height of the second groove 9322 is the same at all points, but the heights of the first groove 9321 and the second groove 9322 are different. For example, the distance between the first groove 9321 and the first end 932a of the turbine shaft 932 is less than the distance between the second groove 9322 and the first end 932a of the turbine shaft 932.
[0062] The drive mechanism 900 may include a first drive rod 940, which is connected to the reel locking mechanism 600. The first drive rod 940 is provided with a first sliding post 941, which is slidably disposed within a first groove 9321 and a second groove 9322. When the first sliding post 941 slides from the first groove 9321 to the second groove 9322, or from the second groove 9322 to the first groove 9321, the first drive rod 940 can drive the reel locking mechanism 600 to change its state. In non-operating scenarios, the first sliding post 941 is located within the first groove 9321.
[0063] Furthermore, the first slide groove 9321 and the second slide groove 9322 can be connected by a first connecting groove 9323. The first connecting groove 9323 is inclined relative to the end face of the first end 932a of the turbine shaft 932. At the connection position between the first connecting groove 9323 and the first slide groove 9321, the groove wall of the first connecting groove 9323 and the groove wall of the first slide groove 9321 are connected by curved surfaces to achieve a smooth transition. Similarly, at the connection position between the first connecting groove 9323 and the second slide groove 9322, the groove wall of the first connecting groove 9323 and the groove wall of the second slide groove 9322 can also be connected by curved surfaces to achieve a smooth transition. Through this design, on the one hand, the risk of the first slide column 941 getting stuck can be reduced, and on the other hand, the first slide column 941 can slide relatively smoothly from the first slide groove 9321 to the second slide groove 9322, thereby improving the driving smoothness of the reel locking mechanism 600.
[0064] In some embodiments, the circumferential surface of the turbine shaft 932 may also be provided with a third groove 9324 and a fourth groove 9325. The third groove 9324 and the fourth groove 9325 extend circumferentially along the turbine shaft 932, and the third groove 9324 and the fourth groove 9325 are in communication. The distance between the third groove 9324 and the first end 100a is different from the distance between the fourth groove 9325 and the first end 100a. This can also be understood as the third groove 9324 having the same height at all points, and the fourth groove 9325 having the same height at all points, but the heights of the third groove 9324 and the fourth groove 9325 being different. For example, the distance between the third groove 9324 and the first end 932a of the turbine shaft 932 is greater than the distance between the fourth groove 9325 and the first end 932a of the turbine shaft 932.
[0065] In one implementation, the third groove 9324 and the fourth groove 9325 may be located on the side of the second groove 9322 away from the first end 932a of the turbine shaft 932. Of course, in some other implementations, the third groove 9324 and the fourth groove 9325 may also be located on the side of the first groove 9321 facing the first end 100a.
[0066] Please continue referring to Figures 3 and 4. The drive mechanism 900 also includes a second drive rod 950, which is connected to the magnetic head cleaning mechanism 800. The second drive rod 950 is provided with a second sliding column 951, which is slidably disposed within the third sliding groove 9324 and the fourth sliding groove 9325. When the second sliding column 951 slides from the third sliding groove 9324 to the fourth sliding groove 9325, or from the fourth sliding groove 9325 to the third sliding groove 9324, the first drive rod 940 can drive the cleaning brush 810 of the magnetic head cleaning mechanism 800 to change position. In the non-working scenario, the second sliding column 951 is located within the third sliding groove 9324, and the cleaning brush 810 of the magnetic head cleaning mechanism 800 is located in the second position B.
[0067] Similarly, the third slide groove 9324 and the fourth slide groove 9325 can be connected by a second connecting groove 9326. The second connecting groove 9326 is inclined relative to the end face of the first end 932a of the turbine shaft 932. At the connection position between the second connecting groove 9326 and the third slide groove 9324, the groove wall of the second connecting groove 9326 and the groove wall of the first slide groove 9321 can be smoothly transitioned by a curved surface connection. At the connection position between the second connecting groove 9326 and the fourth slide groove 9325, the groove wall of the second connecting groove 9326 and the groove wall of the fourth slide groove 9325 can also be smoothly transitioned by a curved surface connection. Through this design, on the one hand, the risk of the first slide column 941 getting stuck can be reduced, and on the other hand, the first slide column 941 can slide relatively smoothly from the first slide groove 9321 to the second slide groove 9322, thereby improving the driving smoothness of the reel locking mechanism 600.
[0068] In some embodiments, at least a portion of the third groove 9324 and at least a portion of the first groove 9321 are staggered along the axial direction of the turbine shaft 932 to reduce the risk of interference between the second drive rod 950 and the first drive rod 940 in non-operating scenarios. Similarly, at least a portion of the fourth groove 9325 and at least a portion of the second groove 9322 are staggered along the axial direction of the turbine shaft 932 to reduce the risk of interference between the second drive rod 950 and the first drive rod 940 in other scenarios.
[0069] Referring to Figures 3 and 4, the drive mechanism 900 may further include a connecting shaft 960 and a third drive rod 970. The connecting shaft 960 may be connected to one axial end of the turbine 930. For example, in one implementation, the connecting shaft 960 is connected to the end of the turbine body 931 facing away from the turbine shaft 932. In one implementation, the end face of the connecting shaft 960 facing the turbine 930 is provided with a shaped plug 961. The cross-sectional shape of the shaped plug 961 can be any shape other than a circle, such as a rhombus, square, serrated, etc. The end face of the turbine body 931 facing away from the turbine shaft 932 is provided with a shaped hole 9311, the cross-sectional shape of which is the same as the cross-sectional shape of the shaped plug 961. The irregularly shaped plug 961 of the connecting shaft 960 can be inserted into the irregularly shaped hole 9311 of the turbine body 931. Through the cooperation between the irregularly shaped plug 961 and the irregularly shaped hole 9311, the connecting shaft 960 can rotate synchronously with the turbine 930 under the drive of the turbine 930. Of course, in some other embodiments, the connecting shaft 960 and the turbine 930 can also be connected by means of threaded connection, adhesive bonding, etc.
[0070] The end face of the connecting shaft 960 facing away from the turbine 930 includes a third sliding column 962. The third sliding column 962 is eccentrically positioned relative to the axis of the connecting shaft 960, allowing it to rotate in a circular motion as the connecting shaft 960 rotates with the turbine 930. A third drive rod 970 is located on the side of the connecting shaft 960 facing away from the turbine 930. The third drive rod 970 has a fifth sliding groove 971, which includes a first sub-groove 9711 and a second sub-groove 9712 that are connected. The first sub-groove 9711 extends perpendicularly to the extension direction of the third drive rod 970, while the second sub-groove 9712 is an arc-shaped groove. The third sliding column 962 is slidably positioned within the fifth sliding groove 971, and when the memory 1000 is not in operation, the third sliding column 962 is located within the first sub-groove 9711.
[0071] In a specific implementation, the second sub-slot 9712 can be approximately semi-circular, and the radius of the second sub-slot 9712 is equal to the distance between the center of the third sliding column 962 and the center of the connecting shaft 960. That is, the radius of the second sub-slot 9712 is equal to the movement radius of the third sliding column 962.
[0072] Please refer to Figure 3 again. During the first drive stroke of the drive mechanism 900, the motor 910 drives the turbine 930 to rotate at a certain angle through the worm gear 920, so that the turbine 930 drives the first slide column 941, the second slide column 951 and the third slide column 962 to slide.
[0073] Figures 5a to 5c show the positional relationship between the first drive lever 940 and the turbine 930 in non-working, working, and cleaning scenarios, respectively; Figures 6a to 6c show the positional relationship between the second drive lever 950 and the turbine 930 in non-working, working, and cleaning scenarios, respectively; Figures 7a to 7c show the positional relationship between the third drive lever 970 and the turbine 930 in non-working, working, and cleaning scenarios, respectively.
[0074] Referring to Figures 5a and 5b, the first sliding column 941 slides from the first sliding groove 9321 to the second sliding groove 9322 under the drive of the turbine 930. Since the heights of the first and second sliding grooves 9321 and 9322 are different, the height of the first sliding column 941 also changes, thereby causing the overall position of the first drive rod 940 to change. This positional change of the first drive rod 940 can drive the reel locking mechanism to switch from the reel locked state to the reel unlocked state. For example, the first drive rod 940 can change the position of the reel locking mechanism within the housing, thereby locking or unlocking the reel.
[0075] Referring to Figures 6a and 6b, the second slide column 951 slides within the third slide groove 9324 under the drive of the turbine 930. Since the height of each part of the third slide groove 9324 is the same, the height position of the second slide column 951 remains unchanged, and the overall position of the second drive rod 950 does not change, so that the cleaning brush 810 of the magnetic head cleaning mechanism 800 can continue to be held in the second position B (refer to Figure 1).
[0076] Referring to Figures 7a and 7b, the third sliding column 962 slides within the first sub-slot 9711. Since the third sliding column 962 performs circular motion, and the first sub-slot 9711 is a straight groove, the movement of the third sliding column 962 applies a force to the groove wall of the first sub-slot 9711 in the same direction as the extension of the third drive rod 970. Driven by this force, the position of the third drive rod 970 moves. Using the displacement of the third drive rod 970, the handle bar locking mechanism can be switched from the handle bar locked state to the handle bar unlocked state. For example, the third drive rod 970 can change the position of the handle bar locking mechanism within the housing, thereby locking or unlocking the handle bar.
[0077] As can be seen, through the above structural design, the drive mechanism can adjust the reel locking mechanism, the magnetic head cleaning mechanism, and the handle locking mechanism to the state required by the memory in the working scenario during its first drive stroke, thereby ensuring the reliability of the memory in the working scenario.
[0078] Referring again to Figure 3, during the second drive stroke of the drive mechanism 900, the motor 910 continues to drive the turbine 930 to rotate via the worm gear 920, and the turbine 930 continues to drive the first slide 941, the second slide 951, and the third slide 962 to slide. Furthermore, the direction of rotation of the turbine 930 in the second drive stroke is the same as its direction of rotation in the first drive stroke.
[0079] Referring to Figures 5b and 5c, the first sliding column 941 slides within the second sliding groove 9322 under the drive of the turbine 930. Since the height of each part of the second sliding groove 9322 is the same, the height position of the first sliding column 941 remains unchanged, and the overall position of the first drive rod 940 will not change, so that the winding reel locking mechanism can remain in the unlocked state.
[0080] Referring to Figures 6b and 6c, the second slide column 951 slides from the third slide groove 9324 to the fourth slide groove 9325 under the drive of the turbine 930. Since the heights of the third slide groove 9324 and the fourth slide groove 9325 are different, the height of the second slide column 951 will also change, thereby causing the overall position of the second drive rod 950 to change. By utilizing the position change of the second drive rod 950, the cleaning brush 810 of the magnetic head cleaning mechanism 800 can be driven to switch from the second position B to the first position A (refer to Figure 1).
[0081] Referring to Figures 7b and 7c, the third sliding column 962 slides from the first sub-slot 9711 to the second sub-slot 9712 under the drive of the worm gear 920. Since the radius of the second sub-slot 9712 is equal to the radius of motion of the third sliding column 962, the position of the third driving rod 970 will not change during the sliding of the third sliding column 962 in the second sub-slot 9712, so that the handle bar locking mechanism 700 can be kept in the locked state.
[0082] It can be seen that the drive mechanism can adjust the reel locking mechanism, the magnetic head cleaning mechanism, and the handle locking mechanism to the state required by the memory in the cleaning scenario during its second drive stroke, so that the cleaning brush can clean the magnetic head 400 in the first position.
[0083] In some embodiments, the drive mechanism may further include a third drive stroke. During this third drive stroke, the drive mechanism can drive the reel locking mechanism to remain in the unlocked state, drive the handle bar mechanism to remain in the locked state, and drive the cleaning brush of the magnetic head cleaning mechanism to move from the first position to the second position, thereby changing the memory from a cleaning scenario to a working scenario. It is readily understood that the movement strokes of the various components of the drive mechanism (including the motor, worm gear, turbine, first drive rod, second drive rod, and third drive rod) during the third drive stroke are opposite to the movement strokes of the various components of the drive mechanism during the second drive stroke. Therefore, the driving process of the drive mechanism during the third drive stroke will not be described in detail here.
[0084] In some embodiments, the drive mechanism may further include a fourth drive stroke. During this fourth drive stroke, the drive mechanism can switch the reel locking mechanism from an unlocked state to a locked state, switch the handle locking mechanism from a locked state to an unlocked state, and hold the magnetic head cleaning mechanism in a second position, thereby adjusting the memory from a working state to a non-working state, allowing the memory to be removed from the electronic device. It is readily understood that the movement strokes of the various components of the drive mechanism (including the motor, worm gear, turbine, first drive rod, second drive rod, and third drive rod) during the fourth drive stroke are opposite to the movement strokes of the various components during the first drive stroke. Therefore, the driving process of the drive mechanism during the fourth drive stroke will not be described in detail here.
[0085] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
