Description

Technical Field

[0001] The present application relates to the field of mobile backup technology, and in particular to a mobile backup connector and a mobile backup combination device. Background Art

[0002] In some current usage scenarios of mobile terminals (such as mobile phones or tablets), when the phone's memory is insufficient, it is necessary to transfer data from the mobile terminal to an external storage module (such as a hard drive or flash memory card) to free up the mobile terminal's memory space. In current related technologies, the mobile terminal is generally connected to the storage module via a connector, and the mobile terminal needs to power the connector. However, in scenarios where large amounts of data are being transferred, this can easily lead to the mobile terminal's battery being depleted. Alternatively, related technologies exist in which the connector has a built-in power supply, allowing the connector to power itself. However, in scenarios where the mobile terminal has sufficient power, the built-in power supply can result in the connector being larger and heavier. Utility Model Content

[0003] In view of this, it is necessary to provide a mobile backup connector and a mobile backup combination device, which can be self-powered or can reduce size and weight in different scenarios.

[0004] In one embodiment of the present application, a mobile backup connector is provided, including a main body and a power supply. The main body has a slot, a terminal interface and a power supply interface. The slot is used to accommodate a storage module, the terminal interface is used to connect a mobile terminal, the main body is used to connect the storage module and the mobile terminal, so that the storage module and the mobile terminal transmit data. The power supply is detachably connected to the main body, and the power supply is provided with a power connector, which is detachably plugged into the power supply interface. The power supply is used to power the main body.

[0005] When the above-mentioned mobile backup connector is in use, the main body connects the mobile terminal and the storage module to transmit data. In the scenario where the mobile terminal has sufficient power, the mobile terminal supplies power to the main body, and the power supply can be separated from the main body to reduce the overall volume and weight of the mobile backup connector. The user only needs to carry the main body, which improves the convenience of use. In the scenario where the mobile terminal has insufficient power, the main body is connected to the power supply, the power supply supplies power to the main body, and the mobile terminal does not supply power to the main body, so as to save power of the mobile terminal. Therefore, by detachably connecting the main body and the power supply, the user can selectively connect or separate the main body and the power supply in different usage scenarios. When connecting the main body and the power supply, the power of the mobile terminal can be saved, and when separating the main body and the power supply, the overall volume and weight of the mobile backup connector can be reduced, making it easier for the user to carry.

In actual production or use, there may be states that are approximately perpendicular or parallel. For example, in combination with numerical descriptions, perpendicular can refer to the angle between two straight lines being in the range of 90°±10°, perpendicular can also refer to the dihedral angle between two planes being in the range of 90°±10°, and perpendicular can also refer to the angle between a straight line and a plane being in the range of 90°±10°. It is not an absolute description in geometry.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] The following is combined with Figures 1 to 8 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0028] The present application provides a mobile backup connector 100 and a mobile backup assembly device 200, such as Figure 1 As shown, mobile backup device 200 includes a mobile backup connector 100 and a storage module 201. Storage module 201 is detachably mounted on mobile backup connector 100. Mobile backup connector 100 is used to connect storage module 201 to an external mobile terminal 300 and enable data transmission between storage module 201 and mobile terminal 300. For example, mobile backup connector 100 can be a portable backup device; mobile terminal 300 can be a portable electronic product such as a mobile phone, tablet computer, or electronic watch, or a non-portable electronic product such as a desktop computer; storage module 201 can be a hard drive, a flash memory card, or a card reader with a flash memory card; and mobile backup device 200 can be sold in combination with a backup device and a hard drive, a flash memory card, or a card reader with a flash memory card.

[0029] Specifically, in some embodiments, Figures 1 to 3 As shown, the mobile backup connector 100 includes a main body 10 and a power supply 20. The main body 10 has a slot 11, a terminal interface 12, and a power supply interface 13. The slot 11 is used to accommodate a storage module 201, and the terminal interface 12 is used to connect to a mobile terminal 300. The main body 10 is used to connect the storage module 201 to the mobile terminal 300, enabling data transmission between the storage module 201 and the mobile terminal 300. The power supply 20 is detachably connected to the main body 10 and is provided with a power connector 21, which is detachably plugged into the power interface 13. When the power supply 20 is connected to the main body 10, the power connector 21 plugs into the power interface 13, and the power supply 20 supplies power to the main body 10. When the power supply 20 is disconnected from the main body 10, the power connector 21 detaches from the power interface 13, and the power supply 20 does not supply power to the main body 10. For example, the terminal interface 12 can be used to connect to the connector of a data cable to connect to the mobile terminal 300.

[0030] When the mobile backup connector 100 is in use, the main body 10 connects the mobile terminal 300 and the storage module 201 to transmit data. When the mobile terminal 300 has sufficient power, the mobile terminal 300 supplies power to the main body 10, and the power supply 20 can be detached from the main body 10, thereby reducing the overall volume and weight of the mobile backup connector 100. The user only needs to carry the main body 10, improving ease of use. When the mobile terminal 300 has insufficient power, the main body 10 is connected to the power supply 20, and the power supply 20 supplies power to the main body 10, while the mobile terminal 300 does not supply power to the main body 10, thereby saving power in the mobile terminal 300. Therefore, by detachably connecting the main body 10 and the power supply 20, the user can selectively connect or detach the main body 10 and the power supply 20 in different usage scenarios. Connecting the main body 10 and the power supply 20 can save power in the mobile terminal 300, while separating the main body 10 and the power supply 20 can reduce the overall volume and weight of the mobile backup connector 100, making it easier for the user to carry. Therefore, compared with the connectors with built-in power or connectors without built-in power in the related art, the mobile backup connector 100 of the present application can be adaptively changed according to different usage scenarios, thereby improving the user experience.

[0031] In some embodiments, as Figure 4 and Figure 6 As shown, the main body 10 includes a first magnetic part 14, and the power supply 20 includes a second magnetic part 22. When the power supply 20 is connected to the main body 10, the first magnetic part 14 and the second magnetic part 22 are attracted to each other, so that the connection between the power supply 20 and the main body 10 is more stable, reducing the risk of the power supply 20 and the main body 10 being separated.

[0032] In some embodiments, as Figure 2 、 Figure 7 and Figure 8 As shown, the power supply 20 is provided with a storage slot 23. The power connector 21 can rotate relative to the power supply 20 between a storage position and a charging position. When the power connector 21 is in the storage position, it is located within the storage slot 23, facilitating storage of the power supply 20. When the power connector 21 is in the charging position, the power connector 21 extends out of the storage slot 23 to plug into the power interface 13. Because the power connector 21 can be stored in the storage slot 23, when the power supply 20 is not connected to the main body 10, the power connector 21 is protected, reducing the risk of wear and tear on the power connector 21. This also makes it easier to carry or store the power supply 20, improving the user experience of the power supply 20.

[0033] In some embodiments, as Figure 2 and Figure 3As shown, the main body 10 has a first end surface 15, and the power supply 20 has a second end surface 24. The first end surface 15 is formed with a groove 151, and the second end surface 24 is formed with a protrusion 241. When the power supply 20 is connected to the main body 10, the groove 151 accommodates the protrusion 241, and the sidewalls of the groove 151 oppose the sidewalls of the protrusion 241, thereby limiting the main body 10 and the power supply 20. In the illustrated embodiment, the main body 10 and the power supply 20 are connected along the X direction, and the first end surface 15 and the second end surface 24 are arranged opposite each other along the X direction. The sidewalls of the groove 151 and the sidewalls of the protrusion 241 can limit the main body 10 and the power supply 20 in the Y and Z directions, reducing relative shaking between the main body 10 and the power supply 20 in the Y and Z directions and improving the connection stability between the main body 10 and the power supply 20.

[0034] Further optionally, the bottom wall of the groove 151 is parallel to the first end face 15, and the side walls of the groove 151 are inclined relative to the first end face 15, so that the cross-sectional area of ​​the groove 151 gradually decreases from the outside to the inside; the top wall of the protrusion 241 is parallel to the second end face 24, and the side walls of the protrusion 241 are inclined relative to the second end face 24, so that the cross-sectional area of ​​the protrusion 241 gradually decreases from the inside to the outside. When the power supply 20 is connected to the main body 10, the first end face 15 abuts against the second end face 24, and / or the bottom wall of the groove 151 abuts against the top wall of the protrusion 241, thereby limiting the main body 10 and the power supply 20 in the X direction, and the side wall of the protrusion 241 abuts against the side wall of the groove 151, thereby limiting the main body 10 and the power supply 20 in the Y direction and the Z direction. In addition, since the side wall of the groove 151 and the side wall of the protrusion 241 are inclined, they can guide the protrusion 241 to be inserted into the groove 151, thereby improving the feel of connecting the power supply 20 and the main body 10.

[0035] It can also be understood that in other embodiments, the side walls of the groove 151 may also be perpendicular to the first end face 15, and the side walls of the protrusion 241 may also be perpendicular to the second end face 24, so that the side walls of the groove 151 and the side walls of the protrusion 241 both extend parallel to the X direction, so that when the main body 10 is connected to the power supply 20, the side walls of the protrusion 241 and the side walls of the groove 151 can abut against each other in a direction perpendicular to the Y direction and the Z direction, thereby more stably limiting the main body 10 and the power supply 20 in the Y direction and the Z direction, thereby improving the connection stability between the power supply 20 and the main body 10.

[0036] In some embodiments, as Figure 4 、 Figure 5 and Figure 6As shown, the main body 10 includes a main body shell 16, a first end cap 17, a second end cap 18, a circuit board 19, and a bracket 10a. The main body shell 16 extends in the X direction and has a rectangular cylindrical shape. The first end cap 17 and the second end cap 18 are respectively disposed at opposite ends of the main body shell 16 in the X direction. A main body cavity 161 is formed between the main body shell 16, the first end cap 17, and the second end cap 18. The main body cavity 161 is used to accommodate the bracket 10a and the circuit board 19. The bracket 10a includes a surrounding plate 10b and an end plate 10c. The surrounding plate 10b extends in the X direction and has a rectangular cylindrical shape. The end plate 10c is disposed at the end of the surrounding plate 10b facing the second end cap 18. The slot 11 is formed between the end plate 10c and the surrounding plate 10b. The first end cap 17 has an opening 171 connected to the slot 11. The opening 171 is used to allow the storage module 201 to enter and exit the slot 11. The circuit board 19 is disposed between the end plate 10c and the second end cover 18. The end plate 10c is provided with a first through-hole 10d. The circuit board 19 has a storage module connector 191. The storage module connector 191 extends into the slot 11 through the first through-hole 10d and is used to plug the storage module 201, thereby achieving an electrical connection between the storage module 201 and the circuit board 19. The power interface 13 and the terminal interface 12 are both provided on the circuit board 19. The main housing 16 has a second through-hole 162 for exposing the terminal interface 12, and the second end cover 18 has a third through-hole 181 for exposing the power interface 13.

[0037] The second end cap 18 is provided with a first mounting groove 182 on one side within the main body cavity 161, and the first mounting groove 182 is used to mount the first magnetic member 14. The first end surface 15 is formed on the side of the second end cap 18 facing away from the first end cap 17, and the groove 151 is recessed relative to the second end cap 18 in the direction toward the first end cap 17. Further optionally, a third through hole 181 is provided in the center of the second end cap 18, and the second end cap 18 is provided with a first mounting groove 182 on opposite sides of the third through hole 181. Each first mounting groove 182 is provided with a first magnetic member 14, which can improve the connection stability between the main body 10 and the power supply 20.

[0038] In some embodiments, the main housing 16 is provided with a first lamp hole 164 , and the circuit board 19 is provided with a first lamp 192 . Light emitted by the first lamp 192 is emitted from the main housing 16 through the first lamp hole 164 , so that the user can observe the working status of the main body 10 .

[0039] In some embodiments, as Figure 4 、 Figure 5 and Figure 6As shown, the main body 10 further includes a flip door 10e, a rotating shaft 10f, and a first elastic return member 10g. The rotating shaft 10f is disposed on the first end cover 17 and is located within the main body cavity 161. The flip door 10e is rotatably disposed on the rotating shaft 10f and can flip about the rotating shaft 10f relative to the first end cover 17 between a closed position and an open position. When the flip door 10e is in the closed position, it covers the opening 171 to protect the slot 11 and reduce the risk of contamination. When the flip door 10e is in the open position, it opens the opening 171 to allow the storage module 201 to enter the slot 11. The first elastic return member 10g connects the rotating shaft 10f and the flip door 10e and applies force to the flip door 10e, causing it to rotate from the open position to the closed position, so that the flip door 10e can automatically return to its original position and close the opening 171. Exemplarily, the first elastic return member 10g can be a torsion spring wrapped around the rotating shaft 10f.

[0040] Specifically, when a user inserts the storage module 201 into the slot 11, the storage module 201 pushes the flip door 10e, causing it to rotate from the closed position to the open position. Simultaneously, the first elastic return member 10g deforms and generates elastic force until the storage module 201 is plugged into the storage module connector 191. The storage module 201 is then fully installed with the main body 10. At this point, part of the storage module 201 is located inside the slot 11, while the other part is located outside. The storage module 201 presses against the flip door 10e, maintaining it in the open position. When the user removes the storage module 201 from the slot 11, the flip door 10e automatically rotates from the open position to the closed position under the force of the first elastic return member 10g, protecting the slot 11 and reducing the risk of contamination.

[0041] In some embodiments, as Figure 4 、 Figure 5 and Figure 6As shown, the bracket 10a further includes at least one partition 10h, which is positioned within the slot 11 and connects the enclosure 10b and the end plate 10c. The at least one partition 10h divides the slot 111 into at least two layers of sub-slots 111, each layer of sub-slots 111 being configured to accommodate a storage module 201. The first end cap 17 is provided with at least one partition bar 172 in the opening 171, which divides the opening 171 into at least two sub-openings 171a. The number of sub-openings 171a is the same as the number of sub-slots 111, and each sub-opening 171a is configured to allow a storage module 201 to enter and exit the corresponding sub-slot 111. The first end cap 17 is provided with a rotating shaft 10f between each two adjacent sub-openings 171a, and a flip door 10e is provided at each sub-opening 171a. The two adjacent flip doors 10e are rotatably connected to the rotating shaft 10f therebetween, and each rotating shaft 10f is provided with a first elastic return member 10g to return the two adjacent flip doors 10e to their original positions. The circuit board 19 has at least two storage module connectors 191, and the end plate 10c is provided with a first through hole 10d corresponding to each layer of the sub-slot 111. Each storage module connector 191 extends into the corresponding sub-slot 111 through the corresponding first through hole 10d to plug into the storage module 201 in the corresponding sub-slot 111, so that the main body 10 can install more than one storage module 201, so that the mobile terminal 300 can transmit data with two or more storage modules 201 at the same time, thereby improving transmission efficiency.

[0042] Exemplarily, the bracket 10a includes a partition 10h that divides the slot 11 into two sub-slots 111. The first end cap 17 includes a partition bar 172 at the opening 171, dividing the opening 171 into two sub-openings 171a. The circuit board 19 includes two storage module connectors 191. The end plate 10c includes two first through-holes 10d, allowing the main body 10 to simultaneously accommodate two storage modules 201. It is understood that in other embodiments, the number of partitions 10h, sub-slots 111, partition bars 172, and sub-openings 171a may be increased to three or four, etc., as needed. Alternatively, the partitions 10h and partition bars 172 may be omitted, so that the slot 11 and opening 171 only accommodate one storage module 201, thereby making the main body 10 thinner.

[0043] In some embodiments, as Figure 7 and Figure 8As shown, the power supply 20 further includes a power supply housing 25, a third end cap 26, a fourth end cap 27, a battery 28, a battery main board 29, and a second elastic return member 20a. The power supply housing 25 extends in the X direction and is shaped like a rectangular cylinder. The third end cap 26 and the fourth end cap 27 are respectively disposed at opposite ends of the power supply housing 25. A power supply cavity 251 is formed between the power supply housing 25, the third end cap 26, and the fourth end cap 27. The power supply cavity 251 is used to accommodate the battery 28 and the battery main board 29. The battery 28 is disposed in the fourth end cap 27, and the battery main board 29 is disposed in the third end cap 26 and connected to the battery 28. The battery 28 is used to power the circuit board 19 in the main body 10, and the battery main board 29 provides protection for the battery 28 during charging and discharging. A receiving slot 23 is formed in the third end cap 26. The power connector 21 is rotatably mounted on the battery main board 29 and is exposed outside the power supply cavity 251 through the receiving slot 23. The second elastic return member 20a connects the power connector 21 to the battery mainboard 29 and applies force to the power connector 21, causing it to rotate from the charging position toward the storage position, thereby automatically retracting the power connector 21 into the storage slot 23. The battery mainboard 29 also has a charging port 291. The power housing 25 has a fourth through-hole 252 to expose the charging port 291. The charging port 291 is used to connect to external power to charge the battery 28. Exemplarily, the second elastic return member 20a is a metal spring.
