Description

Technical Field

[0001] This utility model belongs to the field of USB flash drive development technology, specifically relating to a USB flash drive with a flip-type cap that does not fall off. Background Technology

[0002] A USB flash drive is a miniature, high-capacity portable storage device that uses a USB interface. It connects to a computer via USB for plug-and-play functionality. USB flash drives are widely used due to their small size and portability. However, with repeated use, the cap often needs to be removed. As the cap is inserted and removed repeatedly, it can loosen, causing it to fall off or even be lost. Therefore, a flip-type USB flash drive with a cap that prevents it from falling off was designed to solve these problems.

[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a USB flash drive with a flip-type cap that does not fall off.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a flip-type USB flash drive with a non-detachable cap, comprising: a housing, the first end of which has an opening communicating with its interior; a circuit board, the circuit board being disposed inside the housing, with a USB interface at one end facing the opening; a cap, the cap being detachably connected to both ends of the housing; and a bracket, one end of which is fixedly connected to the cap, and the other end of which is movably connected to the housing, the cap being able to slide and flip back and forth between the first and last ends of the housing via the bracket.

[0006] Furthermore, the housing includes an upper cover disposed above the circuit board and a lower cover disposed below the circuit board, the upper cover and the lower cover being fixedly connected. In this design, the upper cover and the lower cover can be fixed by ultrasonic welding to prevent the gap between the upper cover and the lower cover from widening and causing the bracket to detach, and also to prevent users from disassembling it themselves, thus affecting the lifespan of the USB flash drive.

[0007] Furthermore, the bracket includes a left connecting rod and a right connecting rod. The sides of the housing are respectively provided with left and right sliding grooves that are adapted to the shapes of the left and right connecting rods. The left and right connecting rods are slidably engaged with the left and right sliding grooves, respectively. In this design, the sliding grooves are adapted to the shapes of the connecting rods, ensuring precise and controllable movement trajectories and preventing skewing or jamming during sliding. The connecting rods, as moving parts, are embedded in the sliding grooves, saving external space and resulting in a compact structure.

[0008] Furthermore, both the left and right slide grooves have T-shaped cross-sections. In this design, the T-shaped slide groove structure effectively prevents the connecting rod from dislodging from the groove opening during movement.

[0009] Furthermore, the left connecting rod has a left retaining rod bent at one end connecting to the left slide groove, and the right connecting rod has a right retaining rod bent at one end connecting to the right slide groove. The bent retaining rods can be embedded into the inner groove of the T-shaped slide groove, preventing them from easily loosening. The left retaining rod and the right retaining rod face opposite directions. This design of two retaining rods facing opposite directions simultaneously constrains the upper and lower edges of the slide groove. The upper and lower retaining rods naturally guide the slide groove to maintain its centered position during sliding, reducing jamming problems caused by assembly errors.

[0010] Furthermore, the inner sides of both the left and right locking rods are provided with planes that fit the groove walls of the left and right sliding grooves, respectively. In this design, the rod is prone to rotation when moving within the groove, and the planes of the locking rods contacting the groove walls can restrict the circumferential rotation of the rods, improving the controllability of the sliding direction.

[0011] Furthermore, the cap and the front end of the housing, as well as the cap and the rear end of the housing, are each provided with a matching snap-fit ​​structure. In this design, the snap-fit ​​structure can be assembled by pressing or snapping, making it easy to operate.

[0012] Furthermore, both the left and right sliding grooves have raised stop points on their inner walls. In this design, the raised points form "stop points," requiring the rod to overcome a certain resistance to slide over them, thus allowing it to stay stably at a specific position and achieving multi-position positioning to meet the need for stopping at different locations.

[0013] Furthermore, the housing is provided with an auxiliary slot for inserting fingers. In this design, the auxiliary slot assists in applying force with the fingers when the USB port is plugged into the computer, making it easier to insert and remove the USB flash drive.

[0014] Furthermore, the housing is equipped with an indicator light, which is electrically connected to the circuit board. In this design, when the USB interface is plugged into a device such as a computer, the indicator light illuminates when the insertion is complete, making it easy to identify whether the insertion is successful.

[0015] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0016] The USB flash drive with a flip-type cap that does not fall off can be installed by pulling and flipping the cap with a bracket, allowing the cap to switch positions back and forth between the two ends of the casing. The flip-type cap design makes it less likely to fall off or be lost, and it is flexible and convenient to operate. This design effectively solves the problem of the cap easily falling off and has high practical value. Attached Figure Description

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] Example:

[0031] See appendix Figure 3 Appendix Figure 4 and attached Figure 5As shown, this embodiment provides a flip-type USB flash drive with a non-detachable cap, including: a housing 1, with an opening at the front end communicating with its interior; a circuit board 2, disposed inside the housing 1, with a USB interface 3 at one end facing the opening; a cap 4, detachably connected to both ends of the housing 1; and a bracket 5, one end of which is fixedly connected to the cap 4, and the other end of which is movably connected to the housing 1. The cap 4 can be flipped back and forth by sliding between the front and rear ends of the housing 1 via the bracket 5, that is: the cap 4 can be flipped back and forth by sliding between the front and rear ends of the housing 1 via the bracket 5.

[0032] See appendix Figure 1 and attached Figure 3 As shown, the housing 1 includes an upper cover 101 disposed above the circuit board 2 and a lower cover 102 disposed below the circuit board 2, with the upper cover 101 and the lower cover 102 fixedly connected. The upper cover 101 and the lower cover 102 together fix the circuit board 2, preventing deformation or loosening caused by unilateral pressure and ensuring even force distribution.

[0033] The upper cover 101 and the lower cover 102 are fixedly connected to prevent the gap between the upper cover 101 and the lower cover 102 from becoming too large and causing the bracket to fall off. It also prevents users from disassembling it themselves, which would affect the lifespan of the USB flash drive.

[0034] Specifically, the upper cover 101 and the lower cover 102 are connected by, but not limited to, ultrasonic welding. Ultrasonic welding provides excellent sealing for the tiny structures at the seams of the USB flash drive, effectively preventing dust and moisture. After the materials at the welded parts are fused, their strength is close to that of the main body, and their resistance to drops and vibrations is superior to traditional glue bonding methods. Ultrasonic welding can avoid glue overflow that could contaminate the internal circuitry or appearance. Ultrasonic welding does not require a curing time and can proceed directly to the next process. Ultrasonic welding is usually completed within 0.1 to 1 second, which is much faster than glue or other fixing methods. The material cost is also low, making it suitable for mass production.

[0035] See appendix Figure 1 and attached Figure 7As shown, the bracket 5 includes a left connecting rod 501 and a right connecting rod 502. The housing 1 has left sliding grooves 103 and right sliding grooves 104 on its two sides, respectively, which are adapted to the shapes of the left connecting rod 501 and right connecting rod 502. The left connecting rod 501 and right connecting rod 502 are slidably engaged with the left sliding grooves 103 and right sliding grooves 104, respectively. The sliding grooves are adapted to the shapes of the connecting rods, ensuring precise and controllable motion trajectory and preventing skewing or jamming during sliding. The connecting rods, as moving parts, are embedded in the sliding grooves, saving external space and resulting in a compact structure. The snap-fit ​​installation eliminates the need for additional fasteners, reducing assembly complexity. The symmetrical layout on both sides balances the force, avoiding stress concentration on one side. The cross-sections of the left sliding groove 103 and right sliding groove 104 are both T-shaped. The T-shaped groove structure effectively prevents the connecting rod from coming out of the groove opening during movement. The larger contact area between the T-shaped groove and the connecting rod results in a more uniform stress distribution, reducing localized wear.

[0036] See appendix Figure 2 As shown, the left connecting rod 501 has a left retaining rod 503 bent at one end connecting to the left slide groove 103, and the right connecting rod 502 has a right retaining rod 504 bent at one end connecting to the right slide groove 104. The bent retaining rods can be embedded in the inner groove of the T-shaped slide groove, and are not easily loosened even under reverse force, resulting in higher reliability and reduced maintenance requirements. The left retaining rod 503 is oriented in the opposite direction to the right retaining rod 504. When the left retaining rod 503 at the end of the left connecting rod 501 bends upward, the right retaining rod 504 at the end of the right connecting rod 502 bends downward, and vice versa. The design of the two retaining rods facing opposite directions can simultaneously constrain the upper and lower edges of the slide groove. The upper and lower retaining rods will naturally guide the slide groove to maintain a centered position during sliding, reducing jamming problems caused by assembly errors; it can also prevent the retaining rods from slipping out of the slide groove when the cap 4 is flipped by the bracket 5. The inner sides of both the left locking rod 503 and the right locking rod 504 are provided with planes 6 that fit the groove walls of the left sliding groove 103 and the right sliding groove 104, respectively. When the rod moves within the groove, it is easy for it to rotate. The planes 6 of the locking rods contact the groove walls, which can limit the circumferential rotation of the rods and improve the controllability of the sliding direction. The rods with planes 6 cut out on their inner sides reduce radial occupation and can be adapted to narrower sliding grooves.

[0037] See appendix Figure 3 As shown, both the head cap 4 and the front end of the housing 1, and the rear end of the head cap 4 and the housing 1, are equipped with mutually compatible snap-fit ​​structures 7. The snap-fit ​​structures 7 can be assembled by pressing or snapping, eliminating complex procedures and allowing for manual operation, making it convenient and efficient. The snap-fit ​​structures 7 are typically integrated inside or on the edge of the component, without occupying extra space. The snap-fit ​​structures 7 can be repeatedly disassembled and reassembled without easily damaging the main body.

[0038] See appendix Figure 1 Appendix Figure 3 Or attached Figure 6As shown, the housing 1 has an auxiliary slot 8 for inserting fingers. The auxiliary slot 8 assists in applying force when the USB port 3 is plugged into the computer, making it easier to insert and remove the USB flash drive. The housing 1 has an indicator light 9, which is electrically connected to the circuit board 2. When the USB port 3 is plugged into a computer or other device, the indicator light 9 illuminates when it is fully inserted, making it easy to identify whether it is properly inserted.

[0039] In this embodiment, one end of the bracket 5 is fixedly connected to the cap 4, and the other end is inserted into the sliding grooves on both sides of the USB flash drive housing 1. The upper cover 101 and lower cover 102 of the USB flash drive both have mounting slots on their sides, which, when combined, form T-shaped grooves on both sides. In use, first open the cap 4, then refer to the attached... Figure 3 Pull the cap 4 forward as shown, then refer to the appendix. Figure 4 As shown, rotate 90°, then move backward and rotate 180°, and finally see the appendix. Figure 5 As shown, the cap 4 is inserted into the tail of the USB flash drive casing 1.

[0040] In some other embodiments, the inner walls of the left slide groove 103 and the right slide groove 104 are provided with raised stop points. The raised points are designed to form "stop points" so that the rod needs to overcome a certain resistance to pass over the raised points when sliding, thereby stopping stably at a specific position (such as between the raised points) to achieve multi-position positioning and meet the need for stopping at different positions.

[0041] The USB flash drive with the flip-type non-detachable cap 4 designed in this utility model can be flipped and rotated by the bracket 5, so that the cap 4 can switch positions back and forth between the two ends of the shell 1 and be installed therewith. The flip-type cap 4 is not easy to fall off or lose, and it is flexible and convenient to operate. This design effectively solves the problem of the cap falling off easily and has high practical value.

[0042] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
