Description

Technical Field

[0001] This utility model relates to the field of USB flash drive technology, specifically a USB flash drive with a closed structure. Background Technology

[0002] A USB flash drive with a sealed structure is a portable data storage device that uses an integrated sealed design to effectively prevent dust and water damage.

[0003] Existing common rotating or sliding USB flash drives have poor physical sealing, making them difficult to effectively resist the intrusion of dust and moisture. Furthermore, when their casings are impacted or dropped, the impact force is directly transmitted to the core chips and circuits, leading to data loss or device damage. Although some separate protective cases exist on the market, they are often loosely structured and cumbersome to operate, failing to organically combine protection and convenience. Therefore, there is an urgent need for a USB flash drive protection solution that can provide comprehensive, high-strength physical protection, especially improving sealing and buffering performance, to fundamentally ensure the safety and durability of storage devices in complex usage environments. Utility Model Content

[0004] The purpose of this invention is to provide a USB flash drive with a closed structure to solve the problem of insufficient protection.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a USB flash drive with a closed structure, including a USB flash drive sleeve, a USB flash drive housing fitted on the outside of the sleeve, a USB flash drive cover hinged to the front end of the housing, the sleeve including a cover, a through hole in the center of the cover, the USB flash drive body fixedly disposed in the through hole, a push button on the upper side of the cover, movable ball joints symmetrically arranged on both sides of the cover, outwardly protruding push posts on both sides of the cover, a rubber rear edge connected to the rear of the push post, a bottom spring connected to the bottom of the cover, and an arc ball joint connected to the bottom end of the bottom spring. The USB flash drive housing includes... The device includes an outer box, with an inner box top on the inner side of the outer box. The inner box top has a ball-holding hole adapted to the movable ball. The top of the outer box has a button passage for the push button to pass through. The bottom of the outer box has a spring passage for the bottom spring and the arc ball plate to move. The USB flash drive cover includes a perforated cover door and a pin-type cover door that are hinged to each other by a pin structure. The outer sides of the perforated cover door and the pin-type cover door are connected to the inner wall of the outer box through a switch spring. The inner sides of the perforated cover door and the pin-type cover door have an arc surface that contacts the push post.

[0006] Furthermore, the front end of the rubber rear edge is provided with multiple post holes, which fit against the rear side of the cover.

[0007] Furthermore, the movable ball is hemispherical and can be slidably accommodated in a plurality of ball-holding holes arranged in an array on the top of the inner box.

[0008] Furthermore, the edge of the push key is provided with a wedge-shaped surface.

[0009] Furthermore, the flat end of the arc ball plate is fixedly connected to the bottom spring, and its sliding convex surface is arranged downwards.

[0010] Furthermore, the perforated cover and the pin-mounted cover engage with the semi-circular outer side of the push column via their inner arc surfaces.

[0011] This utility model has the following beneficial effects: (1) This utility model forms a dynamic sealing interface by tightly fitting the cover and the rubber rear edge, which effectively prevents dust and moisture from entering from the back of the USB flash drive. At the same time, the buffer system composed of the bottom spring and the arc ball plate moves in the spring channel, which can absorb the impact force generated by the drop or impact through the deformation of the spring and the sliding of the arc ball plate, avoiding the impact force from being directly transmitted to the core USB flash drive body. This integrated protection solution constructed by sealing and buffering components fundamentally solves the problem of insufficient physical protection caused by poor sealing and lack of buffering in existing USB flash drives.

[0012] (2) This utility model utilizes the clever cooperation between the push column and the arc surface of the USB flash drive cover to automatically open the cover when the USB flash drive is pushed out, and automatically close the perforated cover and the pin cover with the help of the pull force of the switch spring when it is retracted. This realizes the integrated automatic operation of pushing out the USB flash drive for use and retracting the USB flash drive for protection. The design seamlessly integrates the action of opening and closing the cover with the core process of inserting and removing the USB flash drive, solving the problem of cumbersome operation caused by manually opening and closing the protective cover, and greatly improving the convenience of use and user experience.

[0013] (3) This utility model provides a clear and stable multi-level positioning feel and self-locking function for the push and pull of the USB flash drive by sliding and engaging between the movable ball and the ball holes arranged in an array on the top of the inner box. At the same time, the push key slides under the precise guidance of the key channel, ensuring the smoothness and stability of the operation process. This precise mechanical interaction solves the problems of the existing rotating or sliding USB flash drive with vague feel and easy loosening, as well as the loose structure and inconvenient operation of the separate protective box.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 As shown, this utility model is a USB flash drive with a closed structure, including a USB flash drive sleeve 1, a USB flash drive box 2 sleeved on the outside of the USB flash drive sleeve 1, a USB flash drive cover 3 hinged to the front end of the USB flash drive box 2, the USB flash drive sleeve 1 includes a cover 11, a through hole is opened in the center of the cover 11, and the USB flash drive body 12 is fixedly installed in the through hole. A push button 13 is provided on the upper side of the cover 11, and movable locking balls 14 are symmetrically arranged on both sides of it; The cover 11 is also provided with outwardly protruding push posts 15 on both sides, and a rubber rear edge 16 is connected to its rear side; A bottom spring 17 is connected to the bottom of the cover 11, and an arc ball plate 18 is connected to the bottom end of the bottom spring 17; The front end of the rubber rear edge 16 is provided with multiple post holes and fits against the rear side of the cover 11.

[0019] The movable ball 14 is hemispherical and can be slidably accommodated in a plurality of ball-holding holes 23 arranged in an array on the top 22 of the inner box; The edge of the push key 13 is provided with a wedge-shaped surface; The flat end of the arc ball plate 18 is fixedly connected to the bottom spring 17, and its sliding convex surface is arranged downwards; In this process, the user applies force to the wedge-shaped surface of the push key 13, causing the entire cover 11 and its components to move along a predetermined path. At the same time, the symmetrically arranged movable retaining balls 14 slide within the track of the external structure and sequentially engage with the retaining balls 23 at different positions, achieving multi-level precise positioning during the extension and retraction of the USB flash drive cover 1. Throughout the movement, the rubber rear edge 16 on the rear side of the cover 11 is tightly fitted with the cover 11 through multiple post holes at its front end, dynamically maintaining a sealed interface and effectively preventing dust and moisture from entering from the rear. When the device is subjected to vibration or impact, the impact force is transmitted through the cover 11 to the bottom spring 17. The bottom spring 17 deforms to absorb energy, and the arc ball plate 18 at its bottom end disperses and guides the remaining impact force using its downward sliding convex surface, thereby preventing the impact from directly acting on the USB flash drive body 12. The USB flash drive box 2 includes an outer box body 21, and an inner box top 22 is provided on the top of the inner side of the outer box body 21. The inner box top 22 is provided with a ball-holding hole 23 that is adapted to the movable ball 14. The top of the outer box 21 has a button passage 24 for the push button 13 to pass through, and the bottom inside has a spring passage 25 for the bottom spring 17 and the arc ball plate 18 to move. When the USB flash drive sleeve 1 moves inside the USB flash drive enclosure 2, the outer enclosure 21 serves as an overall support and guide frame. The button passage 24 on its top precisely constrains and guides the forward and backward sliding trajectory of the push button 13, ensuring smooth operation without wobbling. At the same time, the ball-holding holes 23 arranged in an array on the top 22 of the inner enclosure engage and disengage with the movable ball 14 on the USB flash drive sleeve 1 in sequence, providing a multi-level stable positioning function for the extension and retraction of the USB flash drive sleeve 1. At the bottom of the USB flash drive sleeve 1, the spring passage 25 formed on the bottom side inside the outer enclosure 21 provides sufficient and uninterrupted space for the compression and rebound of the bottom spring 17 and the sliding of the arc ball plate 18, ensuring that the buffer mechanism can work effectively. The USB flash drive cover 3 includes a perforated cover door 31 and a pin-mounted cover door 32 that are hinged to each other through a pin structure. The outer sides of the perforated cover door 31 and the pin-mounted cover door 32 are connected to the inner wall of the outer casing 21 through a switch spring 33. The inner sides of the perforated cover door 31 and the pin-mounted cover door 32 form an arc surface that contacts the push column 15; The perforated cover door 31 and the pin-mounted cover door 32 are fitted with the semi-circular outer side of the push column 15 through their inner arc surfaces; When the USB flash drive sleeve 1 is pushed forward, the push posts 15 on both sides move forward and come into contact with the inner arc surfaces of the perforated cover 31 and the pin-mounted cover 32. As the push posts 15 continue to move forward, their semi-circular outer sides cooperate with the arc surfaces of the two covers, converting the horizontal thrust into a torque that causes the two covers to rotate outward around the central pin structure. This overcomes the tension of the switch spring 33 and opens the covers smoothly. When the USB flash drive sleeve 1 is retracted, the push posts 15 disengage from the arc surfaces. At this time, the restoring force of the switch spring 33, which is always connected between the inner wall of the outer casing 21 and the covers, pulls the perforated cover 31 and the pin-mounted cover 32 to rotate around the axis, causing them to close automatically.

[0020] In use, the user pushes the push button 13, which slides in the button passage 24 on the top of the outer casing 21. Its wedge-shaped surface provides operating friction. Pushing the button 13 causes the entire USB flash drive sleeve 1 to slide forward inside the USB flash drive casing 2. At this time, the movable retaining balls 14 on both sides of the sleeve cover 11 slide and position themselves step by step in the retaining ball holes 23 on the top of the inner casing 22. Simultaneously, the push posts 15 on both sides of the sleeve cover 11 move forward, contacting and pressing the inner arc surfaces of the perforated cover door 31 and the pin-type cover door 32 of the USB flash drive cover 3. This forces the two covers to overcome the tension of the switch spring 33 and rotate outward around the perforated pin structure to open. At the same time, the bottom spring 17 and the arc ball plate 18 at the bottom of the sleeve cover 11 slide in the spring passage 25 at the bottom of the outer casing 21 and provide cushioning. Finally, the USB flash drive body 12 is fully extended, and the rubber rear edge 16 remains in contact with the rear side of the sleeve cover 11 to maintain internal sealing. The retraction process is the reverse, requiring the user to push the push button 13. Slide backward in the button passage 24, the USB flash drive sleeve 1 moves backward, the movable ball 14 is re-locked in the ball hole 23, the push post 15 disengages from the cover arc surface, and the switch spring 33 automatically pulls the perforated cover 31 and the pin-mounted cover 32 to close, restoring the fully enclosed state.
