[0021] Reference Figures 1 to 10, an embodiment of the present invention provides a USB flash drive, comprising a first shell 1 and a second shell 2, wherein the second shell 2 has a first rotating shaft 291, and the first shell 1 is provided with a first sliding groove 191 extending along a first direction, wherein the first rotating shaft 291 is arranged in the first sliding groove 191, so that the first rotating shaft 291 slides between a first position and a second position and the second shell 2 can rotate relative to the first shell 1 with the axis of the first rotating shaft 291 as the rotation axis, and the interval between the first position and the second position is less than or equal to the length of the first sliding groove; Reference Figures 1 to 3 The first housing 1 is provided with a first interface 3, a conversion mainboard 91 and a second interface 4, wherein the first interface 3 is used to connect to an external device, and the first interface 3 and the second interface 4 are connected by signals through the conversion mainboard 91; The second housing 2 is provided with a storage mainboard 92, a third interface 5 and a fourth interface 6, the third interface 5 and the fourth interface 6 are provided on different sides of the second housing 2, and the third interface 5 and the fourth interface 6 are connected to the storage mainboard 92 by signals; When the first rotating shaft 291 is located at the first position, the third interface 5 is plugged into the second interface 4, so that the first interface 3 is connected to the storage mainboard 92 by signal; When the first rotating shaft 291 is located at the second position, the third interface 5 is disengaged from the second interface 4, and the third interface 5 and the fourth interface 6 rotate around the first rotating shaft 291 so that at least one of the third interface 5 and the fourth interface 6 can be aligned and inserted into the corresponding interface of the external device.

[0022] In this embodiment, the first interface 3 is a USB interface, the second interface 4 is a Type-C female interface, the third interface 5 is a Type-C male interface, and the fourth interface 6 is a lightning interface. In this embodiment, the second interface 4 and the third interface 5 belong to the same type of interface, and the first interface 3, the second interface 4 and the fourth interface 6 belong to different types of interfaces.

[0023] The third interface 5 and the fourth interface 6 are directly connected to the storage mainboard 92. When the third interface 5 or the fourth interface 6 is directly connected to the external device, data can be directly transmitted to the storage mainboard 92. The first interface 3 needs to be connected to the storage mainboard 92 after the second interface 4 and the third interface 5 are connected. The first interface 3 and the second interface 4 are of different types, so a conversion mainboard 91 needs to be set between the first interface 3 and the second interface 4 to convert the signal of the first interface 3 into the signal of the second interface 4.

[0024] See attached Figures 4 to 6In this embodiment, when the third interface 5 and the fourth interface 6 are directly connected to external devices (such as mobile phones, computers, and mobile hard disks, etc.), refer to Figure 4 (a) Figure 4 (b) Figure 4 (c) First press the first rotating shaft, then directly push the second housing to the second position, push the fourth interface out of the gap between the first clamping plate and the second clamping plate, so that the fourth opening is exposed to the outside, and then insert the fourth interface into the corresponding interface of the external device.

[0025] Refer to Figure 5 (a) Figure 5 (b) and Figure 5 (c) First, press the first rotating shaft to move the second housing to the second position, and then rotate the second housing 2 to a suitable angle to facilitate the third interface 5 to be plugged into an external device to complete data transmission.

[0026] Refer to Figure 6 (a) Figure 6 (b) and Figure 6 (c) When the first interface 3 is inserted into an external device (such as a computer), the third interface 5 needs to be inserted into the second interface 4 first, so that the first interface 3 can convert the data received by the USB interface into data that can be received by the Type-C interface through the conversion motherboard 91, and transmit the converted data to the storage motherboard 92 via the second interface 4 and the third interface 5.

[0027] As an example, the first housing 1 has a base 11, a first clip 12, and a second clip 13. The first interface 3 and the second interface 4 are arranged on opposite sides of the base 11. The second interface 4, the first clip 12, and the second clip 13 are arranged on the same side of the base 11. The first clip 12 and the second clip 13 are arranged at intervals along the second direction. The second interface 4 and the second housing 2 are both arranged in the interval between the first clip 12 and the second clip 13. The first sliding groove 191 is arranged on one of the first clip 12 and the second clip 13, and the first rotation axis 291 is arranged on one side of the second housing 2 along the second direction.

[0028] In this embodiment, the base 11 is in a square shape, and the base 11 has an inner cavity. The inner cavity of the base 11 has a first opening and a second opening. The first opening is arranged on one side of the first direction of the base 11, and the second opening is arranged on the other side of the first direction of the base 11. The first connector is arranged in the first opening, the second interface 4 is arranged in the second opening, and the conversion motherboard 91 is arranged in the inner cavity of the base 11.

[0029] More specifically, in this embodiment, the base 11 also includes an interface shell 14, which is made of plastic. The interface shell 14 is installed in the inner cavity of the base 11, and the interface shell 14 has a cavity. A first mounting port and a second mounting port are respectively arranged on both sides of the cavity. The first mounting port is connected to the first opening, and the second mounting port is connected to the second opening. The first interface 3 is installed in the first mounting port, and the second interface 4 is installed in the second mounting port.

[0030] In this embodiment, the second shell 2 is in the shape of a long block, and the second shell 2 has an inner cavity. A third opening and a fourth opening are provided on opposite sides of the inner cavity of the second shell 2. The third interface 5 is installed in the third opening, and the fourth interface 6 is installed in the fourth opening. The storage motherboard 92 is installed in the inner cavity of the second shell 2.

[0031] Specifically, the second shell 2 in this embodiment includes a first sub-shell 201 and a second sub-shell 202, the first sub-shell 201 and the second sub-shell 202 enclose an inner cavity of the second shell 2, the third opening is set on the first sub-shell 201, and the fourth opening is set on the second sub-shell 202, and the first sub-shell 201 and the second sub-shell 202 are connected into a whole by bonding.

[0032] The base 11, the first clip 12 and the second clip 13 are all made of metal. The first clip 12 and the second clip 13 have a certain elasticity. The first clip 12 and the second clip 13 have a tendency to approach each other. During installation, the second shell 2 can be inserted into the gap between the first clip 12 and the second clip 13. After the second shell 2 is inserted, the first clip 12 and the second clip 13 clamp the second shell 2 to prevent the second shell 2 from falling off from the gap between the first clip 12 and the second clip 13.

[0033] Reference Figure 2 and Figure 3 , and refer to Figures 7 to 10 As an example, the first sliding groove 191 is provided on the first clamping piece 12, the second sliding groove 192 is provided on the second clamping piece 13, the second sliding groove 192 penetrates the second clamping piece 13 along the second direction, and the second sliding groove 192 is parallel to the first sliding groove 191; The second clamping piece 13 is provided with a second rotating shaft 292 , and the second rotating shaft 292 slides in the second sliding groove 192 , so that the second rotating shaft 292 slides in the second sliding groove 192 and rotates around its own axis.

[0034] In this embodiment, the first sliding groove 191 and the second sliding groove 192 are opposite to each other, and the length of the first sliding groove 191 is the same as the length of the second sliding groove 192 .

[0035] In this embodiment, the first sliding groove 191 does not penetrate the first clip 12, that is, the recessed depth of the first sliding groove 191 is less than the thickness of the first clip 12 along the second direction. However, the second sliding groove 192 penetrates the first clip 12 along the second direction, so that the second rotation axis 292 is built into the second sliding groove 192, and a person can push the second housing 2 or push the second rotation axis 292 located in the second sliding groove 192, thereby driving the second housing 2 to rotate or slide.

[0036] Reference Figure 2 and Figure 3 , and refer to Figures 7 to 10 As an example, a first guide column is provided on a side of the first clip 12 close to the second clip 13, and a first guide groove 21 and a second guide groove 22 are provided on the surface of the base 11, the first guide groove 21 is arranged around the first rotating shaft 291, the second guide groove 22 is a linear groove, and one end of the second guide groove 22 is connected to the first guide groove 21; when the first rotating shaft 291 slides between the first position and the second position, the first guide column slides along the second guide groove 22; when the first rotating shaft 291 rotates around its own axis at the second position, the first guide column slides in the first guide groove 21.

[0037] In this embodiment, the cooperation between the first guide column and the first guide groove 21 and the second guide groove 22 is mainly used to limit the trajectory of the second housing 2. Specifically, when the second housing 2 is located at the second position and rotates in situ around the first rotation axis 291, the first guide column is located in the first guide groove 21 and rotates in the annular first guide groove 21. The first guide column allows the second housing 2 to rotate stably to prevent the second housing 2 from deviating during the rotation process.

[0038] When the second shell 2 slides toward the base 11 or away from the base 11, since the first guide groove 21 is connected to the second guide groove 22, the second shell 2 is rotated so that the second guide groove 22 and the first sliding groove 191 are parallel. At this time, the first guide column can enter the second guide groove 22 from the first guide groove 21 and slide along the second guide groove 22, thereby being able to slide repeatedly between the first position and the second position.

[0039] Reference Figure 2 and Figure 3 , and refer to Figures 7 to 10As an example, a first ball protrusion 15 is provided on one side of the first clamp 12 close to the second clamp 13, and the first ball protrusion 15 and the first guide column are arranged at intervals along the first direction; a circular first blind hole is provided on the surface of one side of the second shell 2 close to the first clamp 12, and a first limiting disc 23 is provided in the first blind hole. The first limiting disc 23 and the side wall of the first blind hole surround the first guide groove 21, and a plurality of first limiting holes 25 are provided on the first limiting disc 23, and the plurality of first limiting holes 25 are distributed at intervals around the first rotating shaft 291. The first blind hole, the first limiting disc 23 and the first rotating shaft 291 are coaxial, and when the second shell 2 is located in the second position and rotates with the axis of the first rotating shaft 291 as the rotation axis, the ball protrusion can be inserted into any one of the first limiting holes 25.

[0040] In this embodiment, when the second shell 2 is located at the second position and rotates in place around the first rotation axis 291, as the second shell 2 gradually rotates, the ball protrusion can be inserted from one first limiting hole 25 into another first limiting hole 25. When the ball protrusion is inserted into one of the first limiting holes 25, in the absence of external force, the angle of the second shell 2 relative to the first shell 1 can be maintained at this time.

[0041] In this embodiment, due to the existence of the first guide groove 21, the first guide column can be restricted from sliding toward the base 11 during the rotation process. In other words, when the second housing 2 is located at the second position and rotates in situ, at this time, the first guide column is located in the first guide groove 21, and when the first guide column is subjected to a force toward the base 11 but the second guide column has not moved to a position where the first guide groove 21 and the second guide groove 22 are connected, the first guide column abuts against the side wall of the first limiting disc 23 during this process, and the first limiting disc 23 can restrict the first guide column from moving toward the base 11.

[0042] In this embodiment, when the first rotating shaft 291 is located at the first position, the first rotating shaft 291 is located at one end of the first sliding groove 191, and when the first rotating shaft 291 is located at the second position, the first rotating shaft 291 does not reach the other end of the first sliding groove 191, that is, when the first rotating shaft 291 is in the second position, the side wall of the first rotating shaft 291 and the side walls of the two end portions of the first sliding groove 191 are spaced apart. In this embodiment, the spacing distance between the first position and the second position is less than the length of the first sliding groove.

[0043] In this embodiment, although the length of the first sliding groove 191 is such that the first rotating shaft 291 does not abut the side wall of the end of the first sliding groove 191 when in the second position, the existence of the side wall of the first limiting disk 23 can still limit the movement of the first rotating groove and the second rotating groove between the first position and the second position.

[0044] In actual processing, if the interval between the first position and the second position is completely equal to the length of the first sliding groove 191, the processing is difficult and the cost is high. Therefore, the length of the first sliding groove 191 is slightly increased to facilitate assembly and reduce production costs. When the first guide column needs to move toward the base 11, the second shell 2 is rotated so that the first guide column is located at a position where the first guide groove 21 and the second guide groove 22 are connected. At this time, a force is applied to the first guide column to move toward the base 11, which can drive the first guide column to enter the second guide groove 22, thereby realizing the reciprocating motion of the second shell 2 along the first direction.

[0045] Reference Figure 2 and Figure 3 , and refer to Figures 7 to 10 As an example, a second guide column is provided on the side of the second clamp 13 close to the first clamp 12, and a third guide groove 26 and a fourth guide groove 27 are provided on the surface of the base 11, the third guide groove 26 is arranged around the second rotating shaft 292, the fourth guide groove 27 is a linear groove, one end of the fourth guide groove 27 is connected to the third guide groove 26, and the fourth guide groove 27 is parallel to the second guide groove 22; when the second rotating shaft 292 slides between the first position and the second position, the second guide column slides along the fourth guide groove 27; when the second rotating shaft 292 rotates around its own axis at the second position, the second guide column slides in the third guide groove 26.

[0046] In this embodiment, the third guide groove 26 has the same structure as the first guide groove 21, that is, the orthographic projection of the third guide groove 26 on the surface of the second shell 2 provided with the first guide groove 21 coincides with the orthographic projection of the bottom wall of the first guide groove 21 on the surface of the second shell 2 provided with the first guide groove 21. Similarly, the orthographic projections of the second guide groove 22 and the fourth guide groove 27 on the surface of the second shell 2 provided with the first guide groove 21 coincide. In this embodiment, the first rotating shaft 291 and the second rotating shaft 292 are coaxial. Through the above arrangement, when the second shell 2 slides or rotates, the two side surfaces of the second shell 2 can be synchronized, so that the rotation or sliding action is smooth, and the jamming phenomenon that occurs when the second shell 2 slides or rotates is reduced.

[0047] As an example, a second ball protrusion 16 is provided on the side of the second clamp 13 close to the first clamp 12, and the second ball protrusion 16 and the second guide column are arranged at intervals along the first direction; a circular second blind hole is provided on the surface of the side of the second shell 2 close to the first clamp 12, and a second limiting disk is provided in the second blind hole, and the second limiting disk and the side wall of the second blind hole surround the third guide groove 26, and a plurality of second limiting holes 28 are provided on the second limiting disk, and the plurality of second limiting holes 28 are distributed at intervals around the first rotating axis 291, and the second blind hole, the second limiting disk and the first rotating axis 291 are coaxial, and when the second shell 2 is located at the second position and rotates with the axis of the second rotating axis 292 as the rotation axis, the second ball protrusion 16 can be inserted into any one of the second limiting holes 28.

[0048] The working principle of the second ball protrusion 16 is the same as that of the first ball protrusion 15 and will not be described in detail.

[0049] Reference Figure 3 , Fig. 9 and Fig.10 As an example, an avoidance groove 24 is provided on the first limiting disc 23, one end of the avoidance groove 24 is connected to the first limiting hole 25, and the other end of the avoidance groove 24 is connected to the first guide groove 21, and the avoidance groove 24 is parallel to the second guide groove 22; when the second position moves to the first position, the first ball protrusion 15 can enter the second guide groove 22 along the first limiting hole 25 and the avoidance groove 24 in sequence.

[0050] Reference Figure 2 and Figure 3 , and refer to Figures 7 to 10In this embodiment, when sliding from the second position to the first position, the first ball protrusion 15 needs to slide from the first limiting hole 25 into the first guide groove 21, and then the first ball protrusion 15 enters the second guide groove 22 from the first guide groove 21. At the same time, the second ball protrusion 16 needs to slide from the second limiting hole 28 into the third guide groove 26, and then the second ball protrusion 16 enters the fourth guide groove 27 from the third guide groove 26. In the process that the first ball protrusion 15 enters the first guide groove 21 from the first limiting hole 25 and the second ball protrusion 16 enters the third guide groove 26 from the second limiting hole 28, the second ball protrusion 16 needs to jump from the second limiting hole 28 to the surface of the second limiting disc, and then fall from the surface of the second limiting disc into the third guide groove 26. The avoidance groove 24 provided on the first limiting disc 23 in this embodiment allows the first ball protrusion 15 to enter the first guide groove 21 directly along the avoidance groove 24, without the need for the first ball protrusion 15 to jump from the first limiting hole 25 to the surface of the first limiting disc 23, and without the need to fall from the surface of the first limiting disc 23 into the first guide groove 21. That is, when the second housing 2 slides from the second position to the first position, due to the existence of the avoidance groove 24, when the second ball protrusion 16 jumps from the second limiting hole 28 to the surface of the second limiting disc, the end of the second housing 2 away from the first housing 1 will tilt toward the inclined first clip 12, thereby reducing the jumping of the second ball protrusion 16.

[0051] If the avoidance groove 24 is not provided on the first limiting disc 23, the first ball protrusion 15 jumps from the first limiting hole 25 to the surface of the second shell 2, and the second ball protrusion 16 jumps to the surface of the second shell 2 at the same time. The above two actions will open the first clip 12 and the second clip 13 so that the first clip 12 and the second clip 13 face away from each other, which can easily cause the second shell 2 to break away from the first clip 12 and the second clip 13, affecting normal operation. Even if the second shell 2 does not break away from the first shell 1 when the first clip 12 and the second clip 13 are opened, the user needs to increase the force applied to push the second shell 2 when the second shell 2 slides from the second position to the first position. The increased force is used to overcome the first ball protrusion 15 and the second ball protrusion 16 jumping to the corresponding surface of the second shell 2 at the same time, affecting the user's experience.

[0052] As an example, the second housing 2 further includes a pushing member, which includes a pushing screw and a pushing block 72. The pushing screw is inserted into the second sliding groove 192, one end of the pushing screw is connected to the pushing block 72, and the other end of the pushing screw is connected to the second rotating shaft 292. The side surface of the pushing block 72 away from the pushing bolt 71 is away from the first clamping piece 12 and protrudes out of the second sliding groove 192. In this embodiment, the second sliding groove 192 is a stepped groove, the pushing block 72 is located on the side of the second clamping piece 13 away from the first clamping piece 12, and the pushing block 72 is located outside the second sliding groove 192. The user applies a thrust to the pushing block 72 to drive the second housing 2 to reciprocate along the first direction.

[0053] Compared with the stepped second sliding groove 192 in the above embodiment, in other embodiments, the second sliding groove 192 does not need to be a stepped groove, and the push block 72 is located on the side of the second clip 13 away from the first clip 12 , and the user can directly push the push block 72 .

[0054] In other embodiments, the second sliding groove 192 is also a stepped groove, which includes two grooves, one large and one small, wherein the larger groove is located on the side of the second clip 13 away from the first clip 12, and the pushing block 72 is located in the larger groove of the second sliding groove 192. The surface of the pushing block 72 away from the first clip 12 protrudes out of the second sliding groove 192 in the direction away from the first clip 12. The user can push the part exposed in the second sliding groove 192, thereby driving the second shell 2 to be pushed.

[0055] As an example, the first shell 1 also includes a protective shell and a plug-in cover 82, wherein a housing cavity is provided in the protective shell, and the plug-in cover 82 is provided in the protective shell, and the plug-in cover 82 has a plug-in cavity for accommodating the first interface 3, and the first interface 3 is plugged into the plug-in cover 82. In this embodiment, the protective cover 81 is made of metal, and the plug-in sleeve is made of plastic. The plug-in sleeve is fixed in the protective cover 81 by bonding, and a plurality of convex strips 83 are provided on the side wall of the plug-in cavity, wherein the convex strips 83 and the plug-in sleeve are integrally formed, and when the first interface 3 is inserted into the plug-in cavity, the plurality of convex strips 83 contact the first interface 3, and the plurality of convex strips 83 are used to clamp the first interface 3, and the friction between the plurality of convex strips 83 and the first interface 3 is used to realize the detachable connection between the two.

[0056] In this embodiment, the protective cover 81, the base 11, the first clip 12 and the second clip 13 are all made of metal, and the second shell 2 is also made of metal. The metal material can reduce the damage to the surface of the USB flash drive due to collision, falling, etc.
