[0033] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0034] The data storage device provided in the embodiments of the present disclosure is primarily applicable to portable data storage devices. For example, the data storage device includes an interface electrically connected to a storage component and transmits data to another device (e.g., a terminal) through the interface. For example, the data storage device involved in the embodiments of the present disclosure may be a USB flash drive.

[0035] In the related art, a data storage device includes a storage component, an interface, a shell and a cap. The storage component is located inside the shell, the interface is electrically connected to the storage component, and the interface includes a protruding portion protruding from the shell. The protruding portion of the interface is protected by the cap. Currently, the protection of the interface mostly adopts a split cap covering structure, an integrated push-pull or rotating covering structure. The split cap covering structure is prone to causing the cap to fall off and become confused, especially for a USB flash drive with multiple interfaces, which is not convenient to use. The integrated push-pull or rotating covering structure pushes or rotates the interface out when in use, but these two forms do not provide enough protection for the interface, and the interface is prone to dust accumulation. In addition, the cap of the rotating covering structure can rotate flexibly, but the flexibly rotating cap can easily touch other devices, causing damage to the cap.

[0036] In view of this, an embodiment of the present disclosure provides a data storage device, which includes a cap body with a pull-out structure. The cap body can be rotatably connected to protect the interface connected to the storage component, facilitate use, and prevent the cap body from falling off.

[0037] Figure 1 is a structural diagram showing a data storage device in a closed state according to an exemplary embodiment. Figure 4 is an exploded diagram of a data storage device according to an exemplary embodiment. Figure 5 is a structural diagram of a housing according to an exemplary embodiment. Figure 6 FIG is a structural diagram of a cap body according to an exemplary embodiment. Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown, the data storage device includes a storage component 12, an interface 13, a housing 1, and a cap 2. The storage component 12 is located within the housing 1. The interface 13 is electrically connected to the storage component 12 and includes a protruding portion 133 that protrudes from the housing 1. The housing 1 has a first side surface 15, which is provided with a guide rail 14. The guide rail 14 has a first stopper 141 and a second stopper 142. The cap 2 has a connecting portion 21 that is slidably connected to the guide rail 14 and has a first positioning portion 211. The first stopper 141 and the second stopper 142 are used to limit the first positioning portion 211 as the connecting portion 21 slides along the guide rail 14. When the first stopper 141 limits the first positioning portion 211, the cap 2 engages the protruding portion 133 of the interface 13, and when the second stopper 142 limits the first positioning portion 211, the connecting portion 21 is rotatably connected to the guide rail 14.

[0038] The protruding portion 133 of the interface 13 of the data storage device is used for data transmission with other terminals, and the cap body 2 is used to provide protection for the interface 13. The cap body 2 is connected to the guide rail 14 of the housing 1 via the connecting portion 21. As the connecting portion 21 slides on the guide rail 14, the relative position between the cap body 2 and the housing 1 changes. When the connecting portion 21 slides to the first limit portion 141, as shown in FIG. Figure 1 As shown, the cap body 2 is buckled on the protruding portion 133 of the interface 13 to protect the interface 13. When the connecting portion 21 slides to the second limiting portion 142, the connecting portion 21 is rotatably connected to the guide rail 14. Figure 2 FIG. 4 is a structural diagram showing a data storage device in an open state according to an exemplary embodiment. Figure 3 FIG. 1 is a structural diagram of a data storage device in a folded state according to an exemplary embodiment. When the connecting portion 21 slides to the second limiting portion 142, as shown in FIG. Figure 2 and Figure 3 As shown, the cap body 2 is removed from the interface 13. Since the connecting portion 21 is rotatably connected to the guide rail 14 when the connecting portion 21 slides to the second limiting portion 142, the cap body 2 can be rotated within the extension plane of the first side surface 15, so that the cap body 2 can rotate with the connecting portion 21 to avoid the protruding portion 133 of the interface 13, making it easier for the interface 13 to be inserted into other devices.

[0039] The data storage device provided in the embodiment of the present disclosure utilizes a cap body 2 and a connecting portion 21 connected to the housing 1. The connecting portion 21 is slidably connected to the guide rail 14, thereby achieving a retractable structure for the data storage device. This facilitates the cap body 2's protection of the interface 13. Furthermore, the cap body 2 is rotatably connected to the guide rail 14, facilitating the insertion of the interface 13 into other devices, facilitating use and avoiding the risk of the cap body 2 being lost during use.

[0040] In some embodiments, as Figure 6As shown, the main body of the cap body 2 is a shell structure, and one end of the cap body 2 is provided with an opening for buckling onto the interface 13. One end of the connecting portion 21 is connected to the end of the cap body 2 with the opening, and the other end of the connecting portion 21 is provided with a first positioning portion 211, and the connecting portion 21 is slidably connected to the guide rail 14 through the first positioning portion 211.

[0041] In some embodiments, when the second stopper 142 limits the first positioning portion 211, the connecting portion 21 can be rotated to a predetermined position on the guide rail 14 and secured. The protruding portion 133 of the interface 13 protrudes from the housing 1 in a predetermined direction. When the connecting portion 21 is rotated to the predetermined position, the cap body 2 avoids the protruding portion 133 of the interface 13 in the predetermined direction. This allows the protruding portion 133 of the interface 13 to be inserted into the terminal in the predetermined direction without the cap body 2 interfering with the insertion.

[0042] In some embodiments, the preset direction can be understood as the direction in which the interface 13 is inserted into other devices. The preset direction is generally parallel to the direction in which the guide rail 14 extends. The preset direction can also be understood as the direction in which the cap body 2 can be buckled onto the protruding portion 133 of the interface 13 or away from the protruding portion 133 of the interface 13 when the cap body 2 slides back and forth along the guide rail 14.

[0043] In some embodiments, the data storage device may be provided with two interfaces 13 , the protruding directions of the two interfaces 13 are both parallel to the extending direction of the guide rail 14 , and the protruding directions of the two interfaces 13 are opposite.

[0044] In some embodiments, the preset position includes at least one first position and at least one second position. The connecting portion 21 rotates clockwise from the initial position to the first position by a preset angle and is fixed at the first position. The connecting portion 21 rotates counterclockwise from the initial position to the second position by a preset angle and is fixed at the second position. When the connecting portion 21 is in the initial position, the cap body 2 and the protruding portion 133 of the interface 13 overlap in the preset direction. Figure 2 As shown, the connecting portion 21 slides along the guide rail 14, that is, the connecting portion 21 slides along the preset direction to the position where the first positioning portion 211 is connected to the second limiting portion 142, which is the initial position. The preset angle of rotation of the connecting portion 21 from the initial position to the first position or the second position is sufficient to allow the cap body 2 to clear the protruding portion 133 of the interface 13 in the preset direction.

[0045] In some embodiments, the preset angle is greater than or equal to 90°. Figure 3 As shown, the cap body 2 is rotated 90° clockwise to the first position, so that the cap body 2 completely avoids the protruding portion 133 of the interface 13.

[0046] In some embodiments, the position of the second stopper 142 is adjustable. The clockwise or counterclockwise rotation angle of the cap body 2 can be adjusted based on the position of the second stopper 142. For example, when the second stopper 142 moves away from the interface, the clockwise or counterclockwise rotation angle of the cap body 2 can be less than 90°. In this case, the cap body 2 can still avoid the protruding portion 133 of the interface 13 in the predetermined direction.

[0047] In some embodiments, the guide rail 14 is provided with a third limiting portion 143. When the second limiting portion 142 limits the first positioning portion 211, the third limiting portion 143 is used to limit the rotation position of the connecting portion 21, thereby causing the cap body 2 to rotate with the connecting portion 21 to avoid the protruding portion 133 of the interface 13 and be fixed at the position corresponding to the third limiting portion 143. That is, the setting position of the third limiting portion 143 can be understood as the first position and the second position involved above. In the embodiment of the present disclosure, the setting of the third limiting portion 143 facilitates the fixation of the cap body 2. For example, the cap body 2 will not continue to rotate during the process of inserting the interface 13 into the terminal.

[0048] In some embodiments, the position of the third limiting portion 143 includes the first position where the connecting portion 21 is rotated 90° clockwise around the second limiting portion 142 in the extension plane of the first side surface 15, that is, the position where the cap body 2 is turned downward by 90°, see Figure 3 The position of the third limiting portion 143 includes the position where the connecting portion 21 is rotated 90° counterclockwise around the second limiting portion 142 in the extension plane of the first side surface 15, that is, the position where the cap body 2 is turned upward by 90°, which is not shown in the figure.

[0049] In some embodiments, the connecting portion 21 is further provided with a second positioning portion 212. The third limiting portion 143 is used to limit the second positioning portion 212 during the rotation of the connecting portion 21. During the rotation of the connecting portion 21, the second positioning portion 212 cooperates with the third limiting portion 143 to fix the connecting portion 21 in the first and second positions.

[0050] In some embodiments, Figure 5 FIG. 4 is a structural diagram of a housing according to an exemplary embodiment. Figure 6 FIG is a structural diagram of a cap body according to an exemplary embodiment. Figure 5 and Figure 6 As shown, the third limiting portion 143 includes a third limiting hole 151, which mates with the second positioning protrusion 214. During the rotation of the connecting portion 21, the second positioning protrusion 214 engages with the third limiting hole 151, thereby limiting the rotational position of the connecting portion 21. By providing multiple third limiting holes 151, the connecting portion 21 can be limited to multiple positions (such as the first position and the second position mentioned in the above example).

[0051] In some embodiments, there are two third limiting holes 151. The two third limiting holes 151 are respectively located on opposite sides of the width direction of the guide rail 14. Figure 4 As shown, when the second positioning protrusion 214 is engaged with the two third limiting holes 151 , the connecting portion 21 can be maintained at the first position or the second position.

[0052] In some embodiments, continue to refer to Figure 5 and Figure 6 As shown, the first positioning portion 211 includes a first positioning protrusion 213, and the second positioning portion 212 includes a second positioning protrusion 214. The first positioning protrusion 213 and the second positioning protrusion 214 are arranged adjacent to each other. The first limiting portion 141 includes a first limiting hole 149, and the second limiting portion 142 includes a second limiting hole 150. The first limiting hole 149 and the second limiting hole 150 respectively match the first positioning protrusion 213, that is, the first positioning protrusion 213 can be snapped into the first limiting hole 149 to ensure that the cap body 2 remains stable when buckled onto the interface 13. The first positioning protrusion 213 can be snapped into the second limiting hole 150 to enable the connecting portion 21 to be rotatably connected.

[0053] In some embodiments, continue to refer to Figure 5 and Figure 6 As shown, the guide rail 14 includes a guide groove 144. The first positioning protrusion 213 is located in the guide groove 144, and the guide groove 144 has a length direction that is in the same direction as the preset direction. The first positioning protrusion 213 can slide in the guide groove 144 along the length direction of the guide groove 144. That is, the sliding direction of the first positioning protrusion 213 is controlled by the guide groove 144, thereby realizing the sliding connection between the connecting portion 21 and the guide rail 14. Among them, the length direction of the guide groove 144 is consistent with the orientation of the interface 13. The first limiting hole 149 and the second limiting hole 150 are opened on the inner side wall of the guide groove 144, and are used to limit the first positioning protrusion 213 located in the guide groove 144. The third limiting hole 151 is opened on the outer side wall of the guide groove 144, that is, the third limiting hole 151 is opened on the first side surface 15 of the shell 1, and is used to limit the second positioning protrusion 214. When the first positioning protrusion 213 of the connecting portion 21 slides in the guiding groove 144 to the second limiting hole 150 and is engaged with the second limiting hole 150 , the second positioning protrusion 214 is engaged with the third limiting hole 151 .

[0054] In some embodiments, the embodiment of the present disclosure can provide a third limiting hole 151 adjacent to the second limiting hole 150. The third limiting hole 151 is located on one side of the length direction of the guide rail 14, so that when the second positioning protrusion 214 is inserted into the third limiting hole 151, the connecting portion 21 can be fixed in the initial position.

[0055] In some embodiments, the guide groove 144 is provided with a boss 145. The boss 145 is located on the inner side wall of the guide groove 144. The second limiting hole 150 is provided on the boss 145. A first chamfer 146 is provided on one side of the boss 145 facing the length direction of the guide groove 144. By providing the second limiting hole 150 on the boss 145, unstable engagement between the first positioning protrusion 213 and the second limiting hole 150 due to the depth difference between the second limiting hole 150 and the guide groove 144 is avoided. In addition, by providing the second limiting hole 150 on the boss 145, excessive squeezing of the first positioning protrusion 213 on the guide groove 144 can be avoided, thereby allowing the first positioning protrusion 213 to slide more smoothly in the guide groove 144. By providing the boss 145, the depth from the bottom of the second limiting hole 150 to the extended plane of the first side surface 15 is the same as the depth from the bottom of the guide groove 144 to the extended plane of the first side surface 15, thereby ensuring that the first positioning protrusion 213 can slide within the guide groove 144 and engage within the second limiting hole 150. The provision of the first chamfer 146 facilitates the first positioning protrusion 213 to slide to the side of the boss 145 where the second positioning protrusion 214 is provided.

[0056] In some embodiments, the first limiting hole 149 and the second limiting hole 150 are respectively disposed on two bosses.

[0057] In some embodiments, as Figure 6 As shown, the main body of the first positioning protrusion 213 is a columnar structure, one end of the first positioning protrusion 213 is connected to the connecting portion 21, and the other end is provided with a third chamfer 148 to facilitate the first positioning protrusion 213 to slide to the side of the boss 145 where the second positioning protrusion 214 is provided.

[0058] In some embodiments, the guide groove 144 includes a dovetail groove, and the first positioning protrusion 213 is a truncated cone structure that matches the dovetail groove to enhance the connection stability between the guide groove 144 and the first protrusion.

[0059] In some embodiments, the width of the opening of the guide groove 144 is smaller than the width of the bottom of the guide groove 144. The main body of the first positioning protrusion 213 is a frustum structure, and one side of the upper bottom surface of the frustum structure of the first positioning protrusion 213 is connected to the connecting portion 21. The diameter of the upper bottom surface of the frustum structure of the first positioning protrusion 213 is smaller than the width of the opening of the guide groove 144. The diameter of the lower bottom surface of the frustum structure of the first positioning protrusion 213 is larger than the width of the opening of the guide groove 144, and the diameter of the lower bottom surface of the frustum structure of the first positioning protrusion 213 is smaller than the width of the bottom of the guide groove 144.

[0060] For example, Figure 7a FIG is a schematic diagram of the guide groove 144 and the first positioning protrusion 213 according to an exemplary embodiment. Figure 7aAs shown, the length of the guide groove 144 is its guiding direction. The width of the opening of the guide groove 144 is the distance between the two ends of the opening in the width direction of the guide groove 144, which is the preset length B. The bottom width of the guide groove 144 is the distance between the two opposite sides of the bottom in the width direction of the guide groove 144, which is the preset length D. The diameter of the upper bottom surface of the frustum structure of the first positioning protrusion 213 is the preset length A. The diameter of the lower bottom surface of the frustum structure of the first positioning protrusion 213 is the preset length C.

[0061] Figure 7b 1 is a schematic diagram of the guide groove 144 and the first positioning protrusion 213 according to another exemplary embodiment. Figure 7b As shown, the guide groove 144 is a T-shaped groove, and the first positioning protrusion 213 is a T-shaped structure matching it.

[0062] In some embodiments, the end 152 of the guide rail 14 facing the preset direction is provided with a second chamfer 147 , and the second chamfer 147 is used to cooperate with the first positioning protrusion 213 to slide into the guide groove 144 for easy installation.

[0063] In some embodiments, as Figure 5 As shown, housing 1 includes a second side surface 16 and a third side surface 17 connected to first side surface 15. The edges of second side surface 16 and third side surface 17 protrude from first side surface 15 in a direction perpendicular to first side surface 15 to form a sliding stopper 11. Sliding stopper 11 and first side surface 15 form a limiting space 19 extending along guide rail 14. Sliding stopper 11 limits the position of connecting portion 21, allowing connecting portion 21 to slide within limiting space 19.

[0064] In some embodiments, the sliding limiting portion 11 and the connecting portion 21 may be in direct contact to ensure stable sliding, or a gap may be left therebetween to ensure smooth sliding.

[0065] The sliding stopper 11 is used to limit the sliding process of the connecting portion 21, so that when the first positioning protrusion 213 is engaged with the first limiting hole 149 and slides from the first limiting hole 149 to the second limiting hole 150, the connecting portion 21 can only slide and cannot rotate, so that the cap body 2 is buckled onto the interface 13. When the first positioning protrusion 213 is engaged with the second limiting hole 150, the connecting portion 21 leaves the sliding stopper 11, which does not affect the rotation of the connecting portion 21.

[0066] In some embodiments, the guide rail 14 is provided with sliding limit portions 11 located on both sides of the guide groove 144. The sliding limit portions 11 protrude from the surface of the guide rail 14 and extend in the same direction as the guide rail 14. The sliding limit portions and the guide rail 14 form a limit space 19 extending along the guide rail 14. The sliding limit portions are used to limit the connection portion 21 so that the connection portion 21 slides within the limit space 19.
