[0031] Combination Figure 1 and Figure 3 As shown, this application embodiment provides a backup device, including a housing 10, a circuit board 20, a data cable 30, and a suction cup 40. The housing 10 is provided with a first through hole 11 and a second through hole 12. The circuit board 20 is disposed inside the housing 10 and is provided with a charging interface and a memory card slot. The charging interface is directly opposite to the first through hole 11, and the memory card slot is directly opposite to the second through hole 12. One end of the data cable 30 extends into the housing 10 and is electrically connected to the circuit board 20. The other end of the data cable 30 is provided with a connector 50. The suction cup 40 is disposed on the housing 10.

[0032] During use, the memory card is inserted into the memory card slot through the second through hole 12 of the housing 10. The memory card provides external storage space. After the connector 50 on the data cable 30 is inserted into a device such as a mobile phone or computer, documents, photos, or videos stored on the device can be transferred to the memory card via the circuit board 20. When the backup device needs to be charged, an external power source is inserted into the charging port through the first through hole 11 of the housing 10, allowing the external power source to charge the device via the circuit board 20 and the data cable 30. During use, the suction cup 40 on the housing 10 can also be used to attach the housing 10 to the device, ensuring a secure connection and preventing detachment.

[0033] When the housing 10 is attached to the device using the suction cup 40, the housing 10 is connected to the device via a data cable 30, which is flexible and can be bent freely, allowing the housing 10 to be stacked vertically with the device. In actual use, the housing 10 can be attached to the back cover of a mobile phone or tablet using the suction cup 40. Of course, in actual use, users can attach the backup device to smooth surfaces such as desktops and walls, depending on the usage scenario.

[0034] In one embodiment, such as Figure 2 As shown, there are multiple suction cups 40 arranged in a rectangular array. By setting multiple suction cups 40 in a rectangular array, the connection reliability between the backuper and the device can be improved, effectively preventing the backuper from becoming detached from the mobile phone and ensuring stable backup operations. For example, the number of suction cups 40 shown in the figure is in two columns, with each column containing three suction cups 40. Of course, in other embodiments, the number of suction cups 40 can be three, four, five, or more columns, and the number of suction cups 40 in each column can be two, four, five, or more; this is not limited.

[0035] In one embodiment, the suction cup 40 is a silicone suction cup 40. The silicone suction cup 40 has good softness and elasticity, which not only avoids damaging the surface of the device but also allows it to deform according to the shape of the device, thereby enhancing the adsorption effect and improving the connection reliability between the backup device and the device.

[0036] In one embodiment, a charging indicator light is provided on the housing 10, and the charging indicator light is electrically connected to the circuit board 20. The charging indicator light is used to indicate the charging status of the device through light, allowing the user to know the charging status of the device without checking the device's battery level, thereby improving the user experience. Specifically, when the connector 50 of the data cable 30 is inserted into the device, and an external power source is inserted into the charging port through the first through hole 11 of the housing 10, the charging indicator light illuminates to indicate that the device is charging. When the device is fully charged, the color of the charging indicator light can change to indicate that the device is fully charged. For example, when the device is charging, the color of the charging indicator light can be red or yellow, or it can transition from red to yellow. When the device is fully charged, the color of the charging indicator light changes to green.

[0037] In one embodiment, the charging indicator light and the first through hole 11 are located on the same side of the housing 10. By placing the charging indicator light and the first through hole 11 on the same side of the housing 10, when the user inserts an external power source into the charging port through the first through hole 11 of the housing 10, they can directly observe whether the charging indicator light on the same side is lit, making it easier for the user to determine whether the device is charging successfully. In addition, by placing the charging indicator light and the first through hole 11 on the same side of the housing 10, the user is prompted that the first through hole 11 is a charging port, making it easier for the user to distinguish the first through hole 11 from other holes of the housing 10, thus improving ease of use.

[0038] In one embodiment, such as Figure 1 As shown, the housing 10 has a fourth through hole 14, which is located on the same side of the housing 10 as the first through hole 11. The charging indicator light is disposed within the fourth through hole 14. By opening the fourth through hole 14 in the housing 10 and placing the charging indicator light within it, the charging indicator light can be prevented from being exposed, thus enhancing its protection. Furthermore, the charging indicator light can be prevented from protruding from the outer surface of the housing 10, thereby improving the aesthetic appearance of the backup device.

[0039] In one embodiment, such as Figure 3As shown, the housing 10 has a third through hole 13. A cable end clip 60 is provided at the end of the data cable 30 away from the connector 50. The cable end clip 60 passes through the third through hole 13 and partially extends into the housing 10. A locking protrusion 61 is provided on the portion of the cable end clip 60 extending into the housing 10, and the locking protrusion 61 is engaged with the inner wall surface of the housing 10. By providing a cable end clip 60 at the end of the data cable 30 connected to the housing 10, the data cable 30 can be protected, effectively preventing deformation and breakage. The locking protrusion 61 on the portion of the cable end clip 60 extending into the housing 10 engages with the inner wall surface of the housing 10, thus securing the data cable 30 and preventing it from detaching from the housing 10. Furthermore, it covers the gap between the cable end clip and the wall of the third through hole 13, providing a certain degree of waterproofing and dustproofing.

[0040] In one embodiment, combined Figure 1 , Figure 2 and Figure 3 As shown, the housing 10 includes a top plate 15, a bottom plate 16, and side plates 17. The top plate 15 and the bottom plate 16 are arranged parallel to each other and spaced apart. The opposite sides of the side plates 17 are connected to the top plate 15 and the bottom plate 16, respectively. The top plate 15, the bottom plate 16, and the side plates 17 enclose a mounting cavity 18, in which the circuit board 20 is disposed. A suction cup 40 is disposed on the bottom plate 16. The first through hole 11 and the second through hole 12 are both opened in the side plates 17 and are both connected to the mounting cavity 18. The end of the data cable 30 away from the connector 50 passes through the side plates 17 and extends into the mounting cavity 18. The housing 10 is formed by the side plates 17 and the parallel top plate 15 and bottom plate 16, and has the advantages of simple structure, easy manufacturing, and low manufacturing cost. A first through-hole 11 is formed in the side panel 17, allowing an external power source to be inserted into the first through-hole 11 in a direction parallel to the bottom plate 16. The charging interface is set parallel to the bottom plate 16, corresponding to the insertion direction of the external power source. Compared to the charging interface being perpendicular to the bottom plate 16, this reduces the height of the housing 10, i.e., reduces the gap between the top plate 15 and the bottom plate 16, making the backup device more compact and thus improving portability. A second through-hole 12 is formed in the side panel 17, allowing a memory card to be inserted into the second through-hole 12 in a direction parallel to the bottom plate 16. The memory card slot is set parallel to the bottom plate 16, corresponding to the insertion direction of the memory card. Compared to the memory card slot being perpendicular to the bottom plate 16, this reduces the height of the housing 10, i.e., reduces the gap between the top plate 15 and the bottom plate 16, making the backup device more compact and thus improving portability. When the housing 10 is attached to the device by the suction cup 40 on the base plate 16, instead of having the end of the data cable 30 away from the connector 50 pass through the top plate 15 of the housing 10, by having the end of the data cable 30 away from the connector 50 pass through the side plate 17 of the housing 10, it is easier to bend the data cable 30 so that the connector 50 can be connected to the device.

[0041] In one embodiment, the base plate 16 is detachably connected to the side panel 17. The detachability of the base plate 16 and the side panel 17 facilitates the installation of the circuit board 20.

[0042] In one embodiment, combined Figure 1 and Figure 3 As shown, the first through hole 11, the second through hole 12, and the third through hole 13 are respectively provided on the three sides of the side panel 17. Compared with the first through hole 11, the second through hole 12, and the third through hole 13 all being provided on the same side of the side panel 17, by providing the first through hole 11, the second through hole 12, and the third through hole 13 on the three sides of the side panel 17 respectively, it is possible not only to avoid the size of the housing 10 being too large in a certain direction, making the backup device more compact and thus improving portability, but also to make it easier for users to distinguish the first through hole 11 and the second through hole 12, thus improving the convenience of use.

[0043] In one embodiment, combined Figure 1 and Figure 2 As shown, the side panel 17 includes a first side panel 171, a second side panel 172, a third side panel 173, and a fourth side panel 174 connected end to end. The first side panel 171 and the third side panel 173 are arranged opposite each other, and the second side panel 172 and the fourth side panel 174 are arranged opposite each other. The side panel 17 is formed by the first side panel 171, the second side panel 172, the third side panel 173, and the fourth side panel 174, which has the advantages of simple structure, easy manufacturing, and low manufacturing cost. Specifically, the first side panel 171, the second side panel 172, the third side panel 173, the fourth side panel 174, the top panel 15, and the bottom panel 16 are all square plates, which enclose a cuboid shape, making it aesthetically pleasing and forming a cuboid mounting cavity 18, which facilitates the installation of the circuit board 20. For example, a first through hole 11 is formed in a first side plate 171, a third through hole 13 is formed in a third side plate 173, and a second through hole 12 is formed in a second side plate 172 or a fourth side plate 174. In another embodiment, the positions of the first through hole 11 and the third through hole 13 can be interchanged. In another embodiment, the positions of the first through hole 11 and the second through hole 12 can be interchanged. In another embodiment, the positions of the second through hole 12 and the third through hole 13 can be interchanged.

[0044] In one embodiment, the second through hole 12 is tapered towards the mounting cavity 18. This tapering of the second through hole 12 facilitates the insertion of the memory card into the memory card slot, enhancing the user experience.

[0045] In one embodiment, the charging interface is a Type-C interface. Using a Type-C charging interface has at least the following advantages: 1. Reversible insertion, convenient to use; 2. Fast data transfer speed; 3. Supports high-power charging; 4. Rich and diverse functions, supporting the transmission of audio, video, and other signals in addition to charging and data transfer; 5. Good durability and long service life; 6. Stable connection, not easily loosened; 7. Small size, which is conducive to the miniaturization design of the backup device, thereby improving its portability.

[0046] In one embodiment, the connector 50 is a Type-C connector 50. Using a Type-C connector 50 has at least the following advantages: 1. Reversible insertion, convenient to use; 2. Fast data transmission speed; 3. Supports high-power charging; 4. Rich and diverse functions, supporting the transmission of audio, video, and other signals in addition to charging and data transmission; 5. Good durability and long service life; 6. Stable connection, not easily loosened; 7. Small size; 8. Strong compatibility, adaptable to most mobile phones, tablets, laptops, etc.

[0047] In one embodiment, the memory card slot is a Micro-SD card slot. The use of a Micro-SD card slot for inserting Micro-SD cards offers the advantage of small size, facilitating miniaturization of the backup device and improving its portability.

[0048] It should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
