[0040] like Figure 1-7 FIG. 1 is a schematic diagram of an embodiment of a dual-interface data storage device provided by the utility model.

[0041] Please refer to Figure 1-7 This embodiment is used for data storage, and includes a shell 1, the shell 1 is provided with a first outlet 11 and a second outlet 12 arranged opposite to each other, a storage motherboard 2 is provided inside the shell 1, and the storage motherboard 2 is connected to a first USB interface 21 and a second USB interface 22.

[0042] The housing 1 is provided with a driving assembly 3, and the driving assembly 3 rotates to drive the storage mainboard 2 to move linearly, so as to push the first USB interface 21 out of the first outlet 11 to the outside of the housing 1, or to move the first USB interface 21 from the outside of the housing 1 to the inside of the housing 1. The driving assembly 3 rotates to drive the storage mainboard 2 to move linearly, so as to push the second USB interface 22 out of the second outlet 12 to the outside of the housing 1, or to move the second USB interface 22 from the outside of the housing 1 to the inside of the housing 1.

[0043] A gear rack transmission method is adopted between the driving component 3 and the storage mainboard 2. The circular motion of the driving component 3 is converted into the linear motion of the storage mainboard 2 by the gear rack method, driving the storage mainboard 2 to move back and forth inside the shell, and then driving the first USB interface 21 and the second USB interface 22 connected to the storage mainboard 2 to extend and retract inside and outside the shell 1.

[0044] USB interfaces can be classified into three types: USB-Type A, USB-Type B, and USB-Type C. This embodiment adopts two interface structures, USB-Type A and USB-Type C, where the first USB interface is USB-Type A and the second USB interface is USB-Type C.

[0045] In one embodiment, the driving assembly 3 is located in the middle of the housing 1 and is connected to the storage mainboard 2 through the fixing bracket 4. The driving assembly 3 includes a knob 31 and a transmission member 32, wherein the knob 31 is disposed outside the housing 1, the transmission member 32 passes through the surface of the housing 1, the upper side of the transmission member 32 is located outside the housing 1, the upper side of the transmission member 32 is fixedly connected to the knob 31, and the lower side of the transmission member 32 is provided with a gear 33, which is located inside the housing 1 and meshes with the rack 41 of the fixing bracket 4.

[0046] The fixing bracket 4 matches the width and height of the inner side of the housing 1, and the transmission member 32 and the gear 33 are an integrated structure. The knob 31 is a cylindrical cover, and a cross key protrusion connected to the transmission member 32 is provided in the middle of the inner side, and a cross groove is provided on the top surface of the upper side of the transmission member 32 to match and position the cross key protrusion.

[0047] Furthermore, a groove 42 for accommodating the gear 33 is provided on the upper side of the fixing bracket 4, and a rack 41 is provided on the vertical side of the groove 42. The direction in which the rack 41 is arranged is parallel to the moving direction of the first USB interface 21 and the second USB interface 22. A buckle 43 is provided on the lower side of the fixing bracket 4, and the buckle 43 fixes the storage motherboard 2 inside the fixing bracket 4. The first USB interface 21 and the second USB interface 22 extend from the front and rear sides of the fixing bracket 4, respectively. The front and rear sides of the fixing bracket 4 are respectively a first limiting portion 44 and a second limiting portion 45. The width of the first limiting portion 44 is greater than the width of the first outlet 11, and is used to limit the length of the first USB interface 21 extending out of the first outlet 11; the width of the second limiting portion 45 is greater than the width of the second outlet 12, and is used to limit the length of the second USB interface 22 extending out of the second outlet 12.

[0048] In addition, the bottom surface of the gear 33 is provided with an annular boss 331, the surface of the annular boss 331 is an arc surface, and the annular boss 331 contacts the bottom of the groove 42. The structural design of the annular boss 331 is used to reduce the friction between the gear 33 and the groove of the fixing bracket 4 when rotating.

[0049] Specifically, the interior of the shell 1 is a cubic cavity, and the fixed bracket 4 corresponds to a cubic structure. The width and height of the fixed bracket 4 respectively match the width and height of the internal space of the shell 1, and the sum of the lengths of the fixed bracket 4, the first USB interface 21 and the second USB interface 22 is approximately the length of the internal space of the shell 1.

[0050] The storage motherboard 2 is accommodated inside the fixing bracket 4, and a groove 42 is provided on the upper surface thereof. A rack 41 is provided on the side wall of the groove 42. A plurality of parallel buckles 43 are provided on the lower side of the fixing bracket 4, and the buckles 43 clamp and fix the edge of the storage motherboard 2.

[0051] The front and rear sides of the fixed bracket 4 are respectively the first limiting portion 44 and the second limiting portion 45 . The front and rear sides specifically refer to the sides opposite to the first outlet 11 or the second outlet 12 . The length of the fixed bracket 4 is the length of the movable range of the fixed bracket 4 inside the shell 1 .

[0052] like Figure 2 As shown, the knob 31 is rotated in the first direction to make the first limit portion 44 abut against the inner wall of the housing 1. At this time, the second USB interface 22 is located inside the housing 1, the first USB interface 21 is located outside the housing 1, and the first USB interface 21 is in the first use position. The first use position is the use position of the first USB interface 21. At this time, the length of the first USB interface 21 outside the housing 1 can be connected to the data socket of the electronic product.

[0053] The knob 31 is rotated in the second direction so that the second limit portion 45 abuts against the inner wall of the housing 1. At this time, the first USB interface 21 is located inside the housing 1, the second USB interface 22 is located outside the housing 1, and the second USB interface 22 is in the second use position. The second use position is the use position of the second USB interface 22. At this time, the length of the second USB interface 22 outside the housing 1 can be connected to the data socket of the electronic product.

[0054] The first direction and the second direction are clockwise or counterclockwise respectively, which are determined according to the direction of engagement between the gear 33 and the rack 41. In this embodiment, the rack 41 is located on the left side of the gear 33, and the rack 41 is engaged with the left side of the gear 33. Therefore, the counterclockwise direction is the first direction and the clockwise direction is the second direction.

[0055] In one embodiment, the middle of the housing 1 protrudes outward to form a boss 13, the knob 31 is covered on the boss 13, the middle of the boss 13 is opened for mounting the transmission member 32, and the inner circumference of the boss 13 is provided with a circle of internal gears 131. The boss 13 is a cylinder, matching the inner shape of the knob 31, the housing 1 protrudes outward to form the boss 13, and a depression is formed inside the corresponding housing 1, and the internal gear 131 is located on the vertical curved surface of the inner depression.

[0056] A symmetrical elastic cantilever 34 is provided on the side of the transmission member 32, and the end of the elastic cantilever 34 is meshed with the inner gear 131. When the knob 31 is rotated, the elastic cantilever 34 is driven to rotate around the center of the transmission member 32. When the first USB interface 21 or the second USB interface 22 is inserted into the socket of the electronic product, a thrust force is applied, and the thrust force causes the rack 41 inside the housing 1 to push the gear 33 to rotate, causing the interface to retreat into the housing 1 and affect the use. The elastic cantilever 34 is used to interfere with the rotation of the gear 33 caused by the thrust force on the interface, so as to avoid the interface retreating during use and affecting the use.

[0057] Furthermore, notches 342 are provided on both sides of the elastic cantilever 34, and the end of the elastic cantilever 34 is an arc surface to reduce the friction when the top of the end engages with the internal gear 131. The elastic cantilever 34 is provided with a positioning protrusion 341, and the inner end surface of the boss 13 is provided with a positioning hole 132, and the shapes of the positioning protrusion 341 and the positioning hole 132 match each other.

[0058] The positioning protrusion 341 is in the positioning hole 132, and at this time, the first USB interface 21 and the second USB interface 22 are completely inside the housing 1. The positioning protrusion 341 and the positioning hole 132 are designed to indicate that the first USB interface 21 and the second USB interface 22 are completely stored inside the housing 1.

[0059] Since the elastic cantilever 34 is elastic, it will deform when rotating with the transmission member 32, so the positioning protrusion 341 can be pulled out from the positioning hole 132. The notch 342 can increase the elastic force of the elastic cantilever 34.

[0060] In one embodiment, the first outlet 11 is a tapered port, the diameter of the port located inside the housing is larger than the first USB interface 21, and the diameter of the port located outside the housing matches the first USB interface 21. The second outlet 12 is a tapered port, the diameter of the port located inside the housing is larger than the second USB interface 22, and the diameter of the port located outside the housing matches the second USB interface 22. This outlet design prevents the interface from getting stuck when it is pushed out.

[0061] In one embodiment, the surface of the knob 31 is provided with a texture 311. The texture 311 can increase the friction when the user uses it, making it easier to rotate the knob 31. The texture 311 can be specifically provided on the end surface or side surface of the knob 31.

[0062] In one embodiment, the outer surface of the housing 1 is provided with a mounting groove 14 for mounting a sign. There may be multiple mounting grooves 14, and the sign is specifically used to display information such as the trademark logo, storage size, etc. of the storage device.

[0063] To summarize, the embodiment provided in this embodiment includes two types of USB interfaces, which are connected through a storage motherboard. When the rotary drive rotates, it pushes the storage motherboard to move linearly, thereby driving the two USB interfaces connected thereto to move linearly. Depending on the direction of rotation, the two USB interfaces respectively pass through the first outlet and the second outlet, thereby realizing the USB interface extending to the outside of the shell or retracting to the inside of the shell.
