[0053] like Figure 1 , Figure 2 and Figure 3 As shown, the USB flash drive provided in this embodiment of the present invention includes a PCB board assembly 100, a housing 200, and a hook 300. The PCB board assembly 100 is disposed inside the housing 200, and the housing 200 has an opening 210 for the PCB board assembly 100 to enter and exit. The hook 300 includes a hook ear 310 and a rotating shaft 320. The hook ear 310 is located outside the housing 200. The two ends of the rotating shaft 320 are connected to the two ends of the hook ear 310 to form a ring structure. The rotating shaft 320 is disposed inside the housing 200 and is rotatably connected to the housing 200. The hook 300 is adapted to switch between a first position and a second position. In the first position, the hook ear 310 is parallel to the surface where the opening 210 is located. In the second position, the hook ear 310 is perpendicular to the surface where the opening 210 is located.

[0054] The USB flash drive of this utility model embodiment mainly consists of a PCB board assembly 100, a housing 200, and a hook 300. The housing 200 has an inner cavity 220 and an opening 210. The PCB board assembly 100 is disposed in the inner cavity 220 and can enter and exit the inner cavity 220 through the opening 210, thus forming the main structure of the USB flash drive. The hook 300 consists of a hook ear 310 and a rotating shaft 320. The two ends of the hook ear 310 are connected by the rotating shaft 320 to form a ring-shaped hook 300 structure. The rotating shaft 320 is rotatably disposed inside the housing 200, and the hook ear 310 is exposed outside the housing 200, thereby forming a rotatable hook 300 on the main structure of the USB flash drive.

[0055] During rotation, the hook 300 can reach a first position and a second position. In the first position, the hook ear 310 is parallel to the surface of the housing 200 where the opening 210 is located. In the second position, the hook ear 310 is perpendicular to the surface of the housing 200 where the opening 210 is located. That is, the hook 300 can switch between the first position and the second position by rotating 90°, which also satisfies the relative rotation between the hook 300 and the USB flash drive body.

[0056] The hook 300 allows for easy attachment of the USB flash drive, solving the problem of it being easily lost. The rotatable ear 310 structure causes a relative change in the position of the housing 200 when rotated, avoiding surrounding objects. This solves the problem of the USB flash drive being easily damaged or worn when it collides with objects attached to the ear 310, which is fixed to the main body of the flash drive. At the same time, when the USB flash drive receives a hard impact at the location where the hook 300 is set, the rotatable ear 310 can also act as a buffer by rotating, reducing the impact force on the main body of the USB flash drive.

[0057] In this embodiment, the housing 200 has an opening 210 on the surface formed in its width and height directions. Therefore, when the hook 300 is in the first position, the hook ear 310 extends along the height direction of the housing 200. At this time, the hook ear 310 is parallel to the surface formed in the width and height directions of the housing 200. When the hook 300 is in the second position, the hook ear 310 extends along the length direction of the housing 200. At this time, the hook ear 310 can be parallel to the surface formed in the width and length directions of the housing 200, or it can be parallel to the surface formed in the height and length directions of the housing 200.

[0058] like Figure 3 , Figure 4 and Figure 5 As shown, according to an embodiment of the present invention, the USB flash drive further includes a fixing block 400, which is disposed on the housing 200. The fixing block 400 is provided with a first groove 410, the extension direction of the first groove 410 is parallel to the surface where the opening 210 is located, and the rotating shaft 320 is disposed in the first groove 410.

[0059] In this embodiment, the USB flash drive mainly consists of a PCB board assembly 100, a housing 200, a hook 300, and a fixing block 400. The fixing block 400 is disposed in the inner cavity 220 of the housing 200. A first groove 410 is provided on the surface of the fixing block 400. The extending direction of the first groove 410 is consistent with the axial direction of the rotating shaft 320, that is, parallel to the surface where the opening 210 is located. The rotating shaft 320 is disposed in the first groove 410 and can rotate within the first groove 410. This means that the fixing block 400 cooperates with the housing 200 to limit the rotation of the rotating shaft 320.

[0060] According to an embodiment of the present invention, the rotating shaft 320 is provided with a protrusion 321, and the surface of the first groove 410 extends into the fixing block 400 to form a first limiting groove 411. In the second position, the protrusion 321 is embedded in the first limiting groove 411. The fixing block 400 is provided with a limiting surface 430. In the first position, the protrusion 321 is located on the limiting surface 430, and the height of the limiting surface 430 is between the opening and the bottom of the first limiting groove 411.

[0061] In this embodiment, a protrusion 321 is provided on the surface of the rotating shaft 320, and a first limiting groove 411 is also provided in the first groove 410. The first limiting groove 411 corresponds to the protrusion 321. During the process of the hook 300 rotating from the first position to the second position, the rotating shaft 320 rotates in the first groove 410, and the protrusion 321 rotates synchronously with the rotating shaft 320 and enters the first limiting groove 411. The protrusion 321 is fixed in the first limiting groove 411, and the hook 300 reaches the second position. In this way, by setting the first limiting groove 411, the rotating shaft 320 is fixed in the first groove 410, preventing the rotating shaft 320 from moving along the axial direction in the first groove 410. At the same time, after the hook 300 rotates from the first position to the second position in the forward direction, the hook 300 can be fixed in the second position and no longer continue to rotate in the forward direction, ensuring the positioning of the hook 300 in the second position.

[0062] In this embodiment, the first groove 410 is an arc-shaped groove that matches the shape of the rotating shaft 320. The two sides of the opening of the first groove 410 are the surfaces of the fixing block 400. The surface near the opening 210 is a limiting surface 430, which is lower than the surface on the other side but higher than the bottom of the first groove 410. This forms a first groove 410 that is higher on one side and lower on the other along a direction perpendicular to the surface where the opening 210 is located. The rotation of the hook 300 between the first and second positions is also achieved on the side where the limiting surface 430 is located. When the hook 300 moves from the second position to the first position, the protrusion 321 rotates from the first limiting groove 411 toward the limiting surface 430 until it moves out of the first limiting groove 411 and the first groove 410 and reaches above the limiting surface 430. When the hook 300 moves from the first position to the second position, the protrusion 321 rotates from the limiting surface 431 toward the first limiting groove 411 until it moves into the first groove 410 and reaches inside the first limiting groove 411. Therefore, the limiting surface 430 can provide spatial limitation and support for the positioning of the hook 300 in the first position.

[0063] like Figure 6 As shown, according to an embodiment of the present invention, the inner wall of the housing 200 is provided with a second limiting groove 230, which is correspondingly provided with the first limiting groove 411. In the first position, the protrusion 321 is embedded in the second limiting groove 230.

[0064] In this embodiment, a second limiting groove 230 is provided on the inner wall of the housing 200. The position of the second limiting groove 230 corresponds to the first limiting groove 411, and the second limiting groove 230 is set directly opposite the limiting surface 430. During the process of the hook 300 rotating from the second position to the first position, the rotating shaft 320 rotates in the first groove 410, and the protrusion 321 rotates synchronously with the rotating shaft 320 and enters the second limiting groove 230. The protrusion 321 is fixed in the second limiting groove 230, and the hook 300 reaches the first position. In this way, by setting the first limiting groove 411, the rotating shaft 320 is fixed in the first groove 410, preventing the rotating shaft 320 from moving along the axial direction in the first groove 410. At the same time, after the hook 300 rotates from the second position to the first position in the reverse direction, the hook 300 can be fixed in the first position and no longer continue to rotate in the reverse direction, ensuring the positioning of the hook 300 in the first position.

[0065] According to one embodiment of the present invention, the inner wall of the housing 200 is provided with a second groove 240, which is correspondingly provided with the first groove 410, and the rotating shaft 320 is provided between the first groove 410 and the second groove 240.

[0066] In this embodiment, a second groove 240 is provided on the inner wall of the housing 200. The extension direction of the second groove 240 is consistent with the axial direction of the rotating shaft 320, that is, it is parallel to the surface where the opening 210 is located. The second groove 240 is directly opposite to the first groove 410, which means that the second groove 240 and the first groove 410 cooperate to surround the outside of the rotating shaft 320. The rotating shaft 320 rotates in the space between the first groove 410 and the second groove 240. The fixing block 400 cooperates with the housing 200 to limit the rotation of the rotating shaft 320.

[0067] According to one embodiment of the present invention, the housing 200 includes an upper cover 250 and a lower cover 260, and a fixing block 400 is disposed between the upper cover 250 and the PCB board assembly 100; the edge of the lower cover 260 is detachably connected to the edge of the upper cover 250, and the lower cover 260 is provided with an opening 210.

[0068] In this embodiment, the housing 200 consists of an upper cover 250 and a lower cover 260. The upper cover 250 and the lower cover 260 are fastened together to form an inner cavity 220. The fixing block 400 cooperates with the fastener 500 to install the hook 300 on the upper cover 250. The lower cover 260 has an opening 210. The fixing block 400 is located between the upper cover 250 and the PCB board assembly 100. The surface of the fixing block 400 facing the upper cover 250 has a first groove 410 and a limiting surface 430. The surface of the upper cover 250 facing the fixing block 400 has a second groove 240 and a second limiting groove 230.

[0069] The upper cover 250 and the lower cover 260 are detachably connected. After disassembly, the upper cover 250 and the hook 300 are integrated, and the lower cover 260 and the PCB board assembly 100 are integrated, which facilitates disassembly and assembly and prevents parts from being scattered and lost due to disassembly and shaking.

[0070] According to one embodiment of the present invention, the USB flash drive further includes a fastener 500, a fixing hole 270 is provided on the inner wall of the housing 200, a mounting through hole 420 is provided on the fixing block 400, and the fastener 500 passes through the mounting through hole 420 and is fastened to the fixing hole 270; the fixing block 400 is provided with a notch 440, and the notch 440 abuts against the edge of the side of the lower cover 260 where the opening 210 is provided.

[0071] In this embodiment, the USB flash drive mainly consists of a PCB board assembly 100, a housing 200, a hook 300, a fixing block 400, and a fastener 500. The fastener 500 fixes the fixing block 400 to the inner wall of the housing 200. The fixing block 400 is also provided with a through mounting hole 420. Correspondingly, a fixing hole 270 is provided on the inner wall of the housing 200 at the position corresponding to the mounting through hole 420. One end of the fastener 500 passes through the mounting through hole 420 and then enters the fixing hole 270, thereby installing and fastening the fixing block 400 to the inner wall of the housing 200.

[0072] The fixing block 400 also has a notch 440 on the surface facing the PCB board assembly 100. The notch 440 is located at the end of the fixing block 400 near the opening 210. The edge of the lower cover 260 has a positioning groove 261 at the position corresponding to the opening 210. The notch 440 abuts against the positioning groove 261 on the edge of the lower cover 260. On the one hand, it can support the fixing block 400, and on the other hand, it can provide positioning for the installation of the lower cover 260 and the upper cover 250, so as to avoid misalignment and movement.

[0073] In this embodiment, the fastener 500 can be a screw, the fixing hole 270 can be a threaded hole, and the mounting through hole 420 can be a smooth hole or a threaded hole. The fastener 500 is threadedly fastened to the housing 200.

[0074] According to one embodiment of the present invention, the USB flash drive further includes a bracket 600 and a push-pull button 700. The bracket 600 is connected to the outside of the PCB board assembly 100. The bracket 600 has a support 610 on the side near the top cover 250, and the support 610 has a mounting hole 611. The top cover 250 has a guide hole 251, the extension direction of the guide hole 251 is perpendicular to the surface where the opening 210 is located, and the guide hole 251 is correspondingly set with the mounting hole 611. The push-pull button 700 has a fixing post 710, which passes through the guide hole 251 and is inserted into the mounting hole 611.

[0075] In this embodiment, the USB flash drive mainly consists of a housing 200, a PCB board assembly 100, a hook 300, a fixing block 400, a fastener 500, a bracket 600, and a push-pull button 700. The bracket 600 is snapped onto the PCB board assembly 100. A support 610 is provided on the top of the bracket 600, and a mounting hole 611 is provided on the support 610. A guide hole 251 is provided in the middle of the upper cover 250 at the position corresponding to the support 610. The extension direction of the guide hole 251 is the length direction of the housing 200. The push-pull button 700 is located outside the upper cover 250, directly opposite the guide hole 251. A fixing post 710 is provided on the side of the push-pull button 700 near the upper cover 250 to fix it so that it can pass through the guide hole 251 and be inserted into the mounting hole 611 of the support 610, thereby realizing the connection between the push-pull button 700, the bracket 600, and the PCB board assembly 100.

[0076] When the push-pull button 700 is pushed, the fixed post 710 can move along the guide hole 251, thereby driving the bracket 600 and the PCB board 110 to move back and forth in a direction perpendicular to the surface of the opening 210. The PCB board assembly 100 can extend out of the opening 210 or retract into the inner cavity 220 of the housing 200, thus satisfying the user's action of pushing the PCB board assembly 100 out of the opening 210 and then pulling the PCB board assembly 100 back out of the opening 210. This ensures the protection of the PCB board assembly 100 inside the housing 200 and facilitates its use. The guide hole 251 guides and positions the PCB board assembly 100 in the direction of movement in and out of the opening 210.

[0077] In this embodiment, the keycap of the push-pull button 700 is elongated. A snap-fit ​​block 620 is provided on the bracket 600, and a snap-fit ​​slot 130 is provided on the PCB board assembly 100.
