Description

Technical Field

[0001] This invention relates to the field of mobile storage device technology, specifically a magnetic connector mobile hard drive with magnetic field guiding function. Background Technology

[0002] A magnetic connector portable hard drive with magnetic field guidance is a portable solid-state drive that connects and transmits data to host devices (such as computers and mobile phones) via a magnetic interface. When connected, the magnetic force will automatically attract the connector and align it with the port on the hard drive, enabling easy connection and quick disconnection.

[0003] In practical use, magnetic connectors use magnetic force to make docking convenient, but the process of unplugging them creates new problems: First, when unplugging a traditional connector, the user needs to shake the connector left and right to pull it out because of the friction between the connector and the interface. This operation itself will cause the plug to apply uneven mechanical stress to the metal spring and the surrounding structure inside the port. Long-term repeated shaking and plugging will accelerate the fatigue and wear of the port's physical structure.

[0004] With the introduction of magnetic connectors, due to the magnetic attraction, users need to apply a much greater vertical pulling force (more violent left and right shaking of the connector) when pulling out the connector. In practice, this operation is often difficult to be performed purely vertically and is easily converted into a lateral prying force on the interface port, which may lead to port loosening, poor contact, or even permanent mechanical damage. Its potential wear rate is higher than that of traditional plug-in interfaces.

[0005] Furthermore, the interface ports of magnetic hard drives are often exposed and lack effective physical protection. This exposes the internal metal contacts to direct corrosion from environmental contaminants such as dust, moisture, and oil, potentially leading to contact oxidation or buildup, affecting signal transmission quality and connection stability. More seriously, because the ports themselves are magnetic, they easily attract ferromagnetic metal debris from the environment, such as staples and metal dust in an office setting. Once these conductive foreign objects accumulate inside the port, they can easily cause short circuits between the power and data pins, potentially resulting in data transmission errors and even posing a serious safety hazard of burning out the device's interface chip.

[0006] Although designs have been developed that incorporate dust covers and other components at the interface, the core value of magnetic connection technology lies in achieving "easy connection without precise alignment" through magnetic attraction. However, the independent dust plugs or protective covers introduced to address the issue of interface exposure objectively restructure the operational logic during use. Users must perform the additional step of "precisely inserting and removing the dust plug" in order to achieve or maintain the protective state of the interface. This operation is inherently contradictory to the "alignment-free" convenience pursued by magnetic connections. Therefore, while such external protection solutions improve the reliability of the interface environment, they inevitably make the usage process more cumbersome.

[0007] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing magnetic connector portable hard drives. Summary of the Invention

[0008] The present invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. Specifically, the purpose of the present invention is to provide a magnetic connector portable hard drive with magnetic field guidance function, so as to solve the problems mentioned in the background technology, such as the difficulty in pulling out the connector due to magnetic force, which leads to damage; the connector being exposed to the outside and susceptible to corrosion and damage; and the fact that adding a protective cover makes the usage process cumbersome.

[0014] The clamping sleeve is connected to the magnetic interface body;

[0015] The pressure bars all extend through both sides of the hard drive casing;

[0016] The first self-locking mechanism includes a locking block disposed at the bottom of the outer wall of the pressure rod, and the bottom of the locking block is movably provided with a locking groove;

[0017] The second self-locking mechanism includes insert rods disposed on both sides of the magnetic interface body, and movable blocks are movably disposed on the outer wall of the insert rods.

[0018] Preferably, a return spring is provided on the outer wall of the pressure rod, and a connecting rod is provided on one side of the return spring;

[0019] One end of the connecting rod is connected to the outer wall of the pressure rod;

[0020] The other end of the connecting rod is connected to a protective plate.

[0021] Preferably, a first telescopic rod is provided at the bottom of the slot, and a first spring is provided around the outer wall of the first telescopic rod;

[0022] The outer wall of the card slot has a groove.

[0023] Preferably, one end of the insertion rod is provided with a fixing head;

[0024] One end of the pressure rod is provided with a cavity, and a second telescopic rod is movably provided at the top of the pressure rod cavity. A second spring is arranged around the outer wall of the second telescopic rod.

[0025] One end of the second telescopic rod is provided with a locking head, and one side of the outer wall of the locking head is inclined.

[0026] Preferably, the lifting plate is provided with a sliding groove, and the sliding rod is adapted to the sliding groove provided with the lifting plate;

[0027] The chute of the lifting plate is inclined.

[0028] Preferably, both sides of the bottom of the outer wall of the hard disk housing are provided with sliding grooves, and the protective plates are movably connected to the sliding grooves of the hard disk housing.

[0029] The hard disk housing has sliding grooves on both sides of the bottom of the inner wall, and the connecting rod passes through the hard disk housing and is located in the sliding groove of the hard disk housing.

[0030] Preferably, one end of the card block is round, and the shape of one end of the card block is adapted to the shape of the card slot.

[0031] Both the material of one end of the card block and the material of the card slot are rubber.

[0032] Preferably, the outer wall of the movable block is inclined, and the inclination angle of the outer wall of the movable block is the same as the inclination angle of one side of the outer wall of the card head.

[0033] Preferably, the diameter of the fixing head is adapted to the diameter of the cavity at one end of the pressure rod;

[0034] The fixing head can slide within the cavity of the slide rod.

[0035] Preferably, one end of the reset spring is connected to one side of the inner wall of the hard disk housing, and the other end of the reset spring is connected to the outer wall of the pressure rod.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] 1. Through a press-and-pull mechanism and a linkage protection mechanism, the magnetic interface body can be automatically retracted into the hard drive housing when disconnection is required, achieving "non-destructive disconnection" of the interface. By pressing the pressure rods on both sides of the housing with their fingers, the sliding rod and the lifting plate can drive the clamping sleeve connected to the magnetic interface body, causing the magnetic interface body to move vertically upward, smoothly "disengaging" from the port and retracting into the housing. This avoids the need for the user to shake the hard drive housing left and right to pull out the magnetic interface body due to the friction between the magnet and the components. It fundamentally avoids damage to the port spring and solder joints by lateral forces, greatly improving the mechanical life of the interface, thereby ensuring the long-term stability of data transmission and reducing the failure rate and maintenance costs of the equipment.

[0038] 2. The pressing and pulling mechanism allows the magnetic interface body to retract as the pressing rod slides, while the connecting rod simultaneously slides the protective plate to one side, automatically sealing the interface opening at the bottom of the hard drive casing. This keeps the magnetic interface body in a closed environment inside the hard drive casing, effectively isolating it from dust, moisture, and metal foreign objects. It also prevents the risk of short circuits caused by magnetic adsorption of iron filings and other impurities, thereby improving the stability of the device and reducing the risk of data loss due to device damage.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Please see Figures 1 to 15 The present invention provides a technical solution: a magnetic connector portable hard drive with magnetic field guiding function, including a hard drive housing 1, a magnetic interface body 5 movably disposed at the bottom of the hard drive housing 1, and further including:

[0057] The active mechanism 2 is located on both sides of the inside of the hard drive casing 1.

[0058] The first self-locking mechanism 3 is located at the bottom of the press-pull mechanism 2;

[0059] The second self-locking mechanism 4 is provided on both sides of the magnetic interface body 5;

[0060] The pressing and pulling mechanism 2 includes a pressure rod 201 movably disposed on both sides of the hard disk housing 1. A slide rod 203 is provided on one side of the outer wall of the pressure rod 201. A lifting plate 204 is movably disposed at one end of the slide rod 203. A clamping sleeve 205 is connected to one side of the outer wall of the lifting plate 204.

[0061] The clamping sleeve 205 is connected to the magnetic interface body 5;

[0062] The pressure rods 201 extend through both sides of the hard disk housing 1;

[0063] The first self-locking mechanism 3 includes a locking block 301 disposed at the bottom of the outer wall of the pressure rod 201, and a locking groove 304 is movably disposed at the bottom of the locking block 301;

[0064] The second self-locking mechanism 4 includes insert rods 401 disposed on both sides of the magnetic interface body 5, and movable blocks 402 are movably disposed on the outer wall of the insert rods 401.

[0065] In this embodiment, the pressing and pulling mechanism 2 and the linkage protection mechanism enable the magnetic interface body 5 to be automatically retracted into the hard drive housing 1 when disconnection is required, achieving "non-destructive removal" of the interface. By pressing the pressure rods 201 on both sides of the housing with their fingers, the sliding rod 203 and the lifting plate 204 can drive the clamping sleeve 205 connected to the magnetic interface body 5, causing the magnetic interface body 5 to move vertically upward, so that it can be smoothly "detached" from the port and retracted into the housing. This avoids the need for the user to shake the hard drive housing 1 left and right to pull out the magnetic interface body 5 due to the friction between the magnet and the components. It fundamentally avoids damage to the port spring and solder joints by lateral force, greatly improves the mechanical life of the interface, and ensures the long-term stability of data transmission, reducing the failure rate and maintenance cost of the equipment.

[0066] A return spring 202 is provided on the outer wall of the pressure rod 201, and a connecting rod 206 is provided on one side of the return spring 202;

[0067] One end of the connecting rod 206 is connected to the outer wall of the pressure rod 201;

[0068] The other end of the connecting rod 206 is connected to a protective plate 207.

[0069] In this embodiment, by pressing and pulling out the mechanism 2, while the pressure rod 201 slides and drives the magnetic interface body 5 to retract, the connecting rod 206 can drive the protection plate 207 to slide to one side synchronously, automatically sealing the interface opening at the bottom of the hard disk housing 1. This allows the magnetic interface body 5 to be kept in the closed environment inside the hard disk housing 1, so that the magnetic interface body 5, which was originally exposed, enters a sealed state. This can effectively isolate the intrusion of dust, moisture and metal foreign objects, and prevent the risk of power short circuit caused by magnetic adsorption of impurities such as iron filings, thereby improving the stability of the device.

[0070] A first telescopic rod 302 is provided at the bottom of the slot 304, and a first spring 303 is provided around the outer wall of the first telescopic rod 302;

[0071] The outer wall of the card slot 304 has a groove.

[0072] In this embodiment, the force and magnetic force are opposite when the magnetic interface body 5 is inserted. However, since the card block 301 and the card slot 304 are in a docking state at this time, and the material of one end of the card block 301 and the material of one end of the card slot 304 are both rubber, a certain friction force will be generated between the card block 301 and the card slot 304. This allows the attraction and friction force between the magnetic interface body 5 and the interface to offset the pushing force during insertion to a certain extent. At this time, the user can push the hard drive housing 1 to insert the magnetic interface body 5 into the interface. (When the card block 301 is reset, the first telescopic rod 302 will be driven by the card slot 304 to retract until the card block 301 and the card slot 304 are re- docked. After that, the first spring 303 will drive the first telescopic rod 302 to reset.)

[0073] A fixing head 403 is provided at one end of the insertion rod 401;

[0074] One end of the pressure rod 201 is provided with a cavity, and a second telescopic rod 404 is movably provided on the top of the cavity of the pressure rod 201. A second spring 405 is arranged around the outer wall of the second telescopic rod 404.

[0075] One end of the second telescopic rod 404 is provided with a clamp 406, and one side of the outer wall of the clamp 406 is inclined.

[0076] In this embodiment, when the pressure rod 201 slides to one side, one end of it will cause the insertion rod 401 to be inserted into the cavity of the pressure rod 201. The locking head 406 provided in the cavity of the pressure rod 201 will be first pushed up by the fixing head 403. As the pressure rod 201 moves, the locking head 406 will be locked on one side of the outer wall of the fixing head 403. When the user releases his hand, in order to prevent the return spring 202 from contracting and causing the pressure rod 201 to reset, the locking state of the locking head 406 and the fixing head 403 can make the pressure rod 201 only move to one side and cannot move in the reset direction. At this time, since the pressure rod 201 is in a state where it can only move to one side, the lifting plate 204, the clamping sleeve 205, the magnetic interface body 5 and the protective plate 207 are all in a fixed state.

[0077] The lifting plate 204 is provided with a sliding groove, and the sliding rod 203 is adapted to the sliding groove provided with the lifting plate 204;

[0078] The chute on the lifting plate 204 is inclined.

[0079] In this embodiment, when the pressure rod 201 is pressed, it slides to one side. At this time, the reset spring 202 is in a stretched state. When the pressure rod 201 moves, the slide rod 203 drives the lifting plate 204 to slide upward through the slide groove opened in the lifting plate 204. When the lifting plate 204 slides, it drives the clamping sleeve 205 to slide upward. The clamping sleeve 205 is connected to the magnetic interface body 5. When the clamping sleeve 205 moves synchronously, it drives the magnetic interface body 5 to move upward synchronously, so that the magnetic interface body 5 "retracts" into the interior of the hard disk housing 1. At the same time, when the pressure rod 201 slides to one side, it drives the protection plate 207 to slide synchronously through the connecting rod 206. When the protection plate 207 slides, it seals the bottom of the magnetic interface body 5 for protection.

[0080] Both sides of the bottom of the outer wall of the hard disk housing 1 are provided with sliding grooves, and the protective plates 207 are movably connected to the sliding grooves of the hard disk housing 1.

[0081] The bottom of the inner wall of the hard disk housing 1 is provided with sliding grooves on both sides, and the connecting rod 206 passes through the hard disk housing 1 and is set in the sliding groove of the hard disk housing 1.

[0082] In this embodiment, the clamping sleeve 205 is connected to the magnetic interface body 5. When the clamping sleeve 205 moves synchronously, it will drive the magnetic interface body 5 to move upward synchronously, so that the magnetic interface body 5 "retracts" into the interior of the hard disk housing 1. At the same time, when the pressure rod 201 slides to one side, it will drive the protection plate 207 to slide synchronously through the connecting rod 206. When the protection plate 207 slides, it will seal the bottom of the magnetic interface body 5 for protection.

[0083] One end of the card block 301 is round, and the shape of one end of the card block 301 is adapted to the shape of the slot 304.

[0084] Both the material of one end of the card block 301 and the material of the slot 304 are rubber.

[0085] In this embodiment, since the card block 301 and the card slot 304 are small in size, the frictional force generated is not large. It only plays a slight limiting role on the magnetic interface body 5. Due to the magnetic attraction, the magnetic interface body 5 itself is close to the interface. Therefore, the force required to push the magnetic interface body 5 into the socket is very small. Moreover, the working process of the magnetic interface body 5 is to automatically attract into the interface through magnetic force. In the actual process, the user only needs to push the magnetic interface body 5 slightly to achieve complete docking.

[0086] The outer wall of the movable block 402 is inclined, and the inclination angle of the outer wall of the movable block 402 is the same as the inclination angle of one side of the outer wall of the card head 406.

[0087] In this embodiment, the locking head 406 is first lifted by the movable block 402, and then descends after reaching one side of the movable block 402. The other side of the outer wall of the locking head 406 is straight. As the return spring 202 contracts, the pressure rod 201 moves to the other side, which drives the movable block 402 to move to the fixed head 403 and fits against it. After the movable block 402 and the fixed head 403 fit together, the locking head 406 continues to move and is lifted by the movable block 402 and the fixed head 403. As the return spring 202 resets, it can drive the pressure rod 201 to move back to the initial position. As the pressure rod 201 resets, the magnetic interface body 5 will extend out of the hard disk housing 1 again, and the protective plate 207 will open synchronously.

[0088] The diameter of the fixing head 403 is matched with the diameter of the cavity at one end of the pressure rod 201;

[0089] The fixed head 403 can slide within the cavity of the slide bar 203.

[0090] In this embodiment, when the pressure rod 201 slides to one side, one end will cause the insertion rod 401 to be inserted into the cavity of the pressure rod 201. The locking head 406 provided in the cavity of the pressure rod 201 will be first pushed up by the fixing head 403. As the pressure rod 201 moves, the locking head 406 will be locked on one side of the outer wall of the fixing head 403. When the user releases his hand, in order to prevent the return spring 202 from contracting and causing the pressure rod 201 to return to its original position, the locking state between the locking head 406 and the fixing head 403 can make the pressure rod 201 only move to one side.

[0091] One end of the reset spring 202 is connected to one side of the inner wall of the hard disk housing 1, and the other end of the reset spring 202 is connected to the outer wall of the pressure rod 201.

[0092] In this embodiment, as the return spring 202 contracts, the pressure rod 201 moves to the other side, which in turn drives the movable block 402 to the fixed head 403 and makes it fit against it. After the movable block 402 fits against the fixed head 403, the pressure rod 406 continues to move and is pushed up by the movable block 402 and the fixed head 403. As the return spring 202 resets, the pressure rod 201 can be moved back to the initial position. As the pressure rod 201 resets, the magnetic interface body 5 will extend out of the hard disk housing 1 again, and the protection plate 207 will open synchronously.

[0093] Working principle: When using this magnetic connector portable hard drive with magnetic field guidance function, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The image shows the hard drive casing 1 in preparation for docking with the interface. At this time, the magnetic interface body 5 is in a semi-fixed state. The user can align the magnetic interface body 5 with the interface and insert it into the interface using the magnetic force of the magnetic interface body 5 to read data. The method to achieve the semi-fixed state of the magnetic interface body 5 is as follows:

[0094] First, the magnetic connector body 5 itself possesses a certain magnetic force. When it approaches the connector, the magnetic force attracts the magnetic connector body 5 to insert into the connector. The force exerted when the magnetic connector body 5 is inserted is opposite to the magnetic force. However, because the locking block 301 and the slot 304 are in a mating state at this time, and both ends of the locking block 301 and the slot 304 are made of rubber, a certain amount of friction is generated between the locking block 301 and the slot 304. (Due to the small size of the locking block 301 and the slot 304, the friction generated is not significant, only slightly affecting the magnetic connector body 5.) The micro-limiting effect allows the attraction and friction between the magnetic interface body 5 and the interface to offset the pushing force during insertion to a certain extent (because of the magnetic attraction, the magnetic interface body 5 is already close to the interface, so the force used to push the magnetic interface body 5 into the socket is very small, and the working process of the magnetic interface body 5 is to automatically attract into the interface through magnetic force. In the actual process, the user only needs to push the magnetic interface body 5 slightly to fully connect). At this time, the user can push the hard drive casing 1 to insert the magnetic interface body 5 into the interface.

[0095] like Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11The image shows the device in a state where it has been used and needs to be removed. Due to the magnetic attraction between the magnetic connector body 5 and the interface, plus the friction between the magnetic connector body 5 and the interface, it is necessary to shake it left and right while pulling it out. This can cause some damage to the magnetic connector body 5. The user can use the pressing and pulling mechanism 2 and the second self-locking mechanism 4 to retract the magnetic connector body 5 into the hard drive housing 1. The specific operation method is as follows:

[0096] The user pinches the levers 201 on both sides of the hard drive housing 1 with their fingers and presses them. When the levers 201 are pressed, they slide to one side. At this time, the reset spring 202 is in a stretched state. When the levers 201 move, the slide bar 203 will drive the lifting plate 204 to slide upward through the slide groove opened in the lifting plate 204. When the lifting plate 204 slides, it will drive the clamping sleeve 205 to slide upward. The clamping sleeve 205 is connected to the magnetic interface body 5. When the clamping sleeve 205 moves synchronously, it will drive the magnetic interface body 5 to move upward synchronously, so that the magnetic interface body 5 "retracts" into the interior of the hard drive housing 1. At the same time, when the levers 201 slide to one side, they will drive the protection plate 207 to slide synchronously through the connecting rod 206. When the protection plate 207 slides, it will seal the bottom of the magnetic interface body 5 for protection.

[0097] Simultaneously, when the pressure rod 201 slides to one side, one end will cause the insertion rod 401 to be inserted into the cavity of the pressure rod 201. The locking head 406 set in the cavity of the pressure rod 201 will be first pushed up by the fixing head 403. As the pressure rod 201 moves, the locking head 406 will be locked on one side of the outer wall of the fixing head 403. When the user releases his hand, in order to prevent the return spring 202 from contracting and causing the pressure rod 201 to reset, the locking state of the locking head 406 and the fixing head 403 allows the pressure rod 201 to move only to one side and cannot move in the reset direction. At this time, since the pressure rod 201 is in a state where it can only move to one side, the lifting plate 204, the clamping sleeve 205, the magnetic interface body 5 and the protective plate 207 are all in a fixed state, so that the equipment is closed.

[0098] Finally, to remove the magnetic interface body 5 again, the user only needs to press the lever 201 once more. When the lever 201 is pressed, it will continue to move towards the movable side. As the lever 201 moves, it will cause the locking head 406 to move synchronously. Since one side of the locking head 406's outer wall is at the same angle as the outer wall of the movable block 402, the locking head 406 will be first lifted by the movable block 402, and then descend after reaching one side of the movable block 402. The other side of the locking head 406's outer wall is straight, and as the return spring 202 retracts... When the compression causes the pressure rod 201 to move to the other side, it will drive the movable block 402 to move to the fixed head 403 through the locking head 406 and fit against it. After the movable block 402 fits against the fixed head 403, the locking head 406 will continue to move and will be pushed up by the movable block 402 and the fixed head 403. As the reset spring 202 resets, it can drive the pressure rod 201 to move back to the initial position. As the pressure rod 201 resets, the magnetic interface body 5 will extend out of the hard disk housing 1 again, and the protection plate 207 will open synchronously.

[0099] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
