Description

Technical Field

[0001] This invention relates to the field of hard disk storage technology, and in particular to a magnetic hard disk enclosure. Background Technology

[0002] Currently, for live streamers and photography enthusiasts, mobile phones with photo and video recording functions have become essential devices for daily life and work, and relying solely on the phone's internal storage is completely insufficient.

[0003] Chinese utility model patent CN221175778U discloses a "magnetically connected circular solid-state drive," specifically a circular solid-state drive that magnetically connects to the iPhone 15, an Apple mobile phone with MagSafe magnetic attachment and external video recording capabilities. This circular solid-state drive connects magnetically to the smartphone, providing external storage for smartphone video recording. The video can be edited directly on a PC, eliminating the need for transferring videos from the smartphone to the PC.

[0004] Since external storage devices are powered by the phone and consume the phone's battery power, the phone's battery life may be relatively reduced after connecting an external hard drive.

[0005] To address this issue, Chinese utility model patent CN221151414U proposes a power-enabled expansion device. The control circuit board has multiple interfaces coupled to it, at least one of which is connected to an external power source, and simultaneously, at least one of these interfaces is connected to the mobile device via a data cable. This device not only expands the storage capacity of the mobile device but also charges it. The hard drive has an interface for connecting to an external power source and also an interface for connecting to the mobile device, allowing the hard drive (expansion device) to continuously receive power and charge the mobile device. This enables functions such as simultaneous recording and charging, hard drive power supply, and mobile phone charging, and allows for uninterrupted power supply. In other words, this type of external storage capable of video recording largely eliminates the problem of battery life.

[0006] Furthermore, the Chinese utility model with announcement number CN222300311U has been expanded to disclose a magnetic hard drive box that can also be used as a similar mobile phone stand. The magnetic hard drive box also includes a bracket, which is rotatably mounted on the bottom cover, and the bracket and the bottom cover are connected by a hinge assembly.

[0007] Furthermore, Chinese utility model patent CN221225842U expands upon this, disclosing a magnetic hard drive enclosure that allows simultaneous magnetic attachment of two devices. The enclosure includes: a body, a circuit board housed within the body, an upper cover sealing the opening of the body, a first magnetic attachment on the upper cover, and a second magnetic attachment at the bottom of the body. Different types of magnetic devices can be attached using the first and second magnetic attachments. For example, the first magnetic attachment can attach to an external magnetic heatsink, while the second magnetic attachment attaches to the back of a mobile phone; or the first magnetic attachment can attach to an external magnetic power bank, while the second magnetic attachment attaches to the back of a mobile phone.

[0008] The aforementioned expansion results in a significant change in the force distribution between the phone and the magnetic hard drive enclosure: For example, when the magnetic hard drive enclosure rotates to open the stand so that it can magnetically attach to the phone while simultaneously supporting the phone (i.e., the magnetic hard drive enclosure also functions as a phone stand), the supporting force of the stand is directly applied to the magnetic attachment points between the phone and the magnetic hard drive enclosure. The magnetic attachment between the magnetic hard drive enclosure and the phone stand needs to withstand a greater separation force; and this separation force becomes even greater when the user taps the phone.

[0009] For example, when the magnetic hard drive enclosure is attached to the external magnetic heat sink via the first magnetic component and to the back of the phone via the second magnetic component, the magnetic adhesion between the magnetic hard drive enclosure and the phone holder needs to withstand greater separation force, that is, it needs to withstand the weight of the magnetic hard drive enclosure and the magnetic heat sink at the same time.

[0010] To prevent the magnetic hard drive from slipping off when supporting or attaching an external magnetic heatsink, a stronger magnet is usually needed to ensure a more secure attachment to the phone. However, this stronger magnet also makes the magnetic hard drive enclosure more difficult to remove from the phone after use, making it a double-edged sword. Summary of the Invention

[0011] To overcome the shortcomings mentioned above, this invention aims to provide a magnetic hard drive enclosure that can controllably increase the connection force between the magnetic hard drive enclosure and the magnetically attached device when used for extended applications such as mobile phone stands or magnetic external attachments, and controllably restore the connection force between the magnetic hard drive enclosure and the magnetically attached device when such extensions are not required.

[0012] To achieve the above objectives, the present invention provides the following technical solution: a magnetic hard drive enclosure, comprising a enclosure body, a main control module, a memory module and a power module disposed inside the enclosure body, and multiple openings provided on the enclosure body, and interfaces or plugs corresponding to the openings are also provided on the enclosure body; The box has a magnetic surface and a functional surface that are arranged opposite to each other; The box is equipped with magnetic components that correspond to the magnetic surface of the device, and the box is magnetically attached to the device by the corresponding magnetic components.

The box is also equipped with an additional connector, which has a switchable connection state and a disconnection state; When the additional connector is in the connected state, it is configured to increase the connection force between the magnetic surface of the device and the magnetically attracted device; when the additional connector is in the disconnected state, it is configured to restore the connection force between the magnetic surface of the device and the magnetically attracted device to the force before the increase. When the functional expansion component is used, the additional connector can be controlled to switch to the connected state; After the functional expansion component has been used or is not in use, the additional connector can be controlled to switch to the disconnected state.

[0013] As a further aspect of the present invention: the additional connector is an electromagnetic connector, which generates magnetic force by energizing the additional connector and cancels the generation of magnetic force by de-energizing the additional connector.

This direct current in the same direction constitutes the magnetic field generated by the energized coil, the direction of which is indicated from the magnetic attraction surface of the device.

[0016] As a further aspect of the present invention: the box body is also provided with a status identification element for identifying the usage status of the functional expansion component; When the main control module identifies the function expansion component as being in use through the status recognition component, the main control module correspondingly controls the coil to be energized through the control circuit. When the main control module identifies that the extended function component is not in use, it will control the coil to cut off power through the control circuit.

[0017] As a further aspect of the present invention: the functional expansion component is a bracket rotatably connected to the functional surface of the box body; The status recognition component is a sensor used to detect whether the bracket has rotated and opened.

[0018] As a further aspect of the present invention: the status identification element is a micro switch installed inside the housing and with its contacts extending through an opening in the functional surface; When the bracket is rotated and opened, the triggering part on the bracket is disengaged from the triggering pressure on the contact of the micro switch.

When the bracket is determined to be rotating open relative to the box, it is identified as being in use; when the bracket is determined not to be rotating open relative to the box, it is identified as being in use.

[0019] As a further aspect of the present invention: the functional expansion component is a second magnetic ring; a second annular positioning groove is formed on an inner wall of the box body near the functional surface, and the second magnetic ring is correspondingly positioned in the second annular positioning groove. The functional surfaces of the box are magnetically connected to the external magnetically attached components via a second magnetic ring; The status recognition component is used to detect whether there is an external magnetically attached component on the functional surface.

If the second magnetic ring successfully attaches the external magnetically attracted component to the functional surface, it is identified as being in use; if the second magnetic ring fails to attach the external magnetically attracted component to the functional surface, it is identified as being in unused.

[0021] As a further aspect of the present invention: the magnetic component is a magnetic ring, and an annular positioning groove is formed on an inner wall of the box body near the magnetic surface of the device, and the magnetic ring is positioned in the annular positioning groove accordingly.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-3 A magnetic hard drive enclosure includes a housing 1, and a main control module 2, a memory module 3 and a power module 4 are disposed inside the housing 1.

[0028] The box body 1 has multiple openings 101, and the box body 1 is also provided with an interface 5 or plug 6 corresponding to the openings.

[0029] For example, it can be connected to a mobile phone through one of the interfaces or plugs 6, and connected to an external power source through the second interface 5 or plug. In this way, the magnetic hard drive enclosure can be continuously powered by an external power source, and the mobile phone can be charged through the magnetic hard drive enclosure, realizing functions such as charging and recording at the same time, powering the hard drive, and charging the mobile phone.

[0030] In some embodiments, the plurality of openings also include a microphone interface 501, which can be used to connect an external microphone 14, thereby adding a sound acquisition device during live streaming or video recording and improving audio quality.

[0031] In this embodiment, the box body 1 has a device magnetic surface 102 and a functional surface 103 arranged opposite to each other.

[0032] The box body 1 is provided with a magnetic component 7 corresponding to the magnetic surface 102 of the device. The box body 1 can be magnetically attached to the magnetically attached device through the magnetic component 7.

[0033] The magnetic component 7 is, for example, a magnetic ring, and the box 1 can be magnetically attached to the back of the mobile phone 13 with MagSafe magnetic attachment function via the magnetic ring.

[0034] In some embodiments, an annular positioning groove 104 is formed on an inner wall of the housing 1 near the magnetic surface 102 of the device, and the magnetic ring is positioned in the annular positioning groove 104.

[0035] In this embodiment, the box body 1 is provided with a functional expansion component corresponding to the functional surface 103.

[0036] Functional expansion components can extend the functionality of the magnetic hard drive enclosure, such as enabling it to be used as a mobile phone stand, or allowing it to magnetically attach to external magnetic heat sinks, etc.

[0037] Correspondingly, the above-mentioned functional expansion results in: the functional expansion component increases the separation force between the magnetic surface of the device and the magnetically attracted device when in use.

[0038] In this embodiment, the housing 1 is also provided with an additional connector 8, which has a switchable connection state and a disconnection state.

[0039] When the auxiliary connector 8 is in the connected state, the connection force between the magnetic surface 102 of the device and the magnetically attracted device is increased; when the auxiliary connector 8 is in the disconnected state, the connection force between the magnetic surface 102 of the device and the magnetically attracted device returns to the force before the increase.

[0040] Thus, when the functional expansion component is used, the additional connector 8 can be switched to the connected state to increase the connection force between the magnetic surface 102 of the device and the magnetically attached device, making it difficult for the housing 1 and the magnetically attached device to separate. After the functional expansion component is no longer in use, the additional connector 8 can be switched to the disconnected state to restore the connection force between the magnetic surface 102 of the device and the magnetically attached device to the force before it was increased, making it easier for the user to remove the magnetic hard drive enclosure for storage.

[0041] Combination Figure 1 , 2In some embodiments, the box body 1 can be cylindrical in shape. The magnetic surface 102 and the functional surface 103 correspond to the two end faces of the box body 1. The opening 101 is set on the outer peripheral surface of the box body 1. The insertion direction of the interface 5 is parallel to the magnetic surface 102 and the functional surface 103, and they are not easy to collide or limit each other.

[0042] In some embodiments, the additional connector 8 is an electromagnetic connector that generates a magnetic force by energizing the additional connector 8 and cancels the generation of the magnetic force by de-energizing the additional connector 8.

[0043] When the additional connector 8 is powered on and generates a magnetic force, the direction of the magnetic force is set to be pointed out from the magnetic surface 102 of the device, so as to further magnetically attract the magnetically attracted device.

[0044] In some embodiments, a coil positioning groove 106 is formed on an inner wall of the housing 1 near the device magnetic surface 102, and the additional connector 8 includes a coil disposed in the coil positioning groove 106.

[0045] In some embodiments, the main control module 2 is provided with a corresponding control circuit 9. The main control module 2 uses the control circuit 9 to perform switchable power-on / power-off control on the coil, so that the auxiliary connector 8 has a switchable connection state and disconnection state.

[0046] In some embodiments, when the coil is energized, a direct current in the same direction is applied, which causes the magnetic field generated by the energized coil to be directed from the magnetic attraction surface 102 of the device, so that the additional connector 8 can provide a magnetic attraction force in the same direction.

[0047] In some embodiments, the housing 1 is further provided with a status identification element 10 for identifying the usage status of the functional expansion component.

[0048] When the main control module 2 identifies the extended function component as being in use via the status recognition element 10, it correspondingly controls the coil to be energized via the control circuit 9. This energizes the coil to generate a magnetic field, causing the housing 1 to be magnetically attracted to the back of the phone with MagSafe magnetic attraction through the magnetic field generated by the coil. In other words, at this time, the housing 1 can be strongly magnetically attracted to the back of the phone 13 with MagSafe magnetic attraction through the magnetic ring and the magnetic field generated by the energized coil, making it difficult for the magnetic hard drive enclosure to detach from the magnetically attracted device.

[0049] When the main control module 2 identifies the extended function component as unused via the status recognition element 10, it correspondingly controls the coil to cut off power through the control circuit 9, thereby canceling the generation of the magnetic field. In this case, the housing 1 is magnetically attached to the back of a phone with MagSafe magnetic attachment only via the magnetic ring, making it easier for the user to remove the magnetic hard drive enclosure from the magnetically attached device.

[0050] By automatically identifying whether the expansion component is in use, the system ensures that the additional connector 8 is in the "use" state when the expansion component is in use, guaranteeing a stable connection between the magnetic hard drive enclosure and the magnetically attached device. Conversely, when the expansion component is not in use, the additional connector 8 is in the "unused" state, allowing users to more easily remove the magnetic hard drive enclosure from the magnetically attached device. This effectively prevents hardware from falling due to a failure to promptly control the connection force of the additional connector when the expansion component is in use, making it smarter and safer to use.

[0051] In some embodiments, the functional expansion component is, for example, a bracket 11 rotatably connected to the functional surface 103 of the housing.

[0052] The status recognition element 10 is, for example, a sensor used to detect whether the bracket 11 has rotated and opened.

[0053] For example, the status recognition component 10 is a micro switch installed inside the housing 1 and whose contacts extend through the opening of the functional surface 103, that is, the functional surface 103 has an opening corresponding to the micro switch.

[0054] When the bracket 11 is rotated open, the triggering part on the bracket 11 is disengaged from the triggering pressure on the contact of the micro switch. By determining whether the micro switch is triggered, it can be determined whether the bracket 11 is rotated open relative to the housing 1.

[0055] When the bracket 11 is determined to be rotating open relative to the box 1, it is identified as being in use; when the bracket 11 is determined not to be rotating open relative to the box 1 (also known as being in rotation retracted), it is identified as being in unused state.

[0056] By automatically recognizing whether the bracket 11 has rotated and opened, the connection between the magnetic hard drive enclosure and the magnetically attached device is automatically strengthened when the magnetic hard drive enclosure is used as a phone holder. Users only need to rotate the bracket 11 to open it. While fulfilling the function of supporting a phone, it is more intelligent and safer to use, and it is less likely to detach from the magnetically attached device during use.

[0057] In some embodiments, the functional extension component is, for example, a second magnetic ring 12. A second annular positioning groove 105 is formed on an inner wall of the housing 1 near the functional surface 103, and the second magnetic ring 12 is correspondingly positioned in the second annular positioning groove 105.

[0058] The functional surface 103 of the box can be magnetically connected to the magnetic heat sink (not shown) via the second magnetic ring 12.

[0059] The status identification element 10 is, for example, used to detect whether an external magnetically attached component (not shown) is magnetically attached to the functional surface 103.

[0060] For example, the status recognition component 10 is a micro switch installed inside the housing and whose contacts extend through an opening on the functional surface 103, that is, the functional surface 103 has an opening corresponding to the micro switch.

[0061] When the magnetic heat sink is magnetically attracted and attached to the functional surface 103 by the second magnetic ring 12, the triggering part on the magnetic heat sink will press and trigger the contact of the micro switch. By determining whether the micro switch is triggered, it can be determined whether the second magnetic ring 12 has magnetically attached the external magnetically attracted component to the functional surface 103.

[0062] When the second magnetic ring 12 is determined to magnetically attach the external magnetically attached component to the functional surface 103, it is identified as being in use; when the second magnetic ring 12 is determined not to magnetically attach the external magnetically attached component to the functional surface 103, it is identified as being in unused.

[0063] By automatically identifying whether the second magnetic ring 12 magnetically attaches the external magnetically attached component to the functional surface 103, the connection between the magnetic hard drive enclosure and the magnetically attached device is automatically enhanced when the magnetic hard drive enclosure is used as an intermediate connector. Users simply need to magnetically attach the external magnetically attached component (such as a magnetic heatsink) to the functional surface 103. This provides a more intelligent and safer experience while fulfilling the intermediate connection function, and it is less likely to detach from the magnetically attached device (such as a mobile phone) when used as an intermediate connector.

[0064] In some embodiments, the second magnetic ring 12 is also configured to adapt to the MagSafe magnetic structure of the mobile phone. That is, the magnetic surface 102 and the functional surface 103 of the device can be selectively used to magnetically attach to the back of a mobile phone with MagSafe magnetic functionality.

[0065] For example, when a mobile phone is connected to a component that can be used as a user handheld device, such as a selfie stick, mobile phone gimbal, or mobile phone cage with a magnetic coupling structure, via a magnetic hard drive enclosure as an intermediate connector, the magnetic surface 102 of the device can be switched to be magnetically attached to the aforementioned handheld device (not shown) with a magnetic coupling structure, and then the functional surface 103 can be magnetically attached to the back of the mobile phone. The status recognition component 10 recognizes that the mobile phone is magnetically attached to the functional surface 103. The main control module 2 controls the coil to be energized through the control circuit 9, so that the magnetic hard drive enclosure can be more securely magnetically connected to the aforementioned handheld device with a magnetic coupling structure.

[0066] In this way, when the user holds the aforementioned handheld device, the magnetic hard drive enclosure with the mobile phone attached is less likely to fall off the handheld device.

[0067] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
