Description

Technical Field

[0001] This utility model belongs to the field of mobile storage device technology, specifically relating to a foldable interface-protected mobile storage card. Background Technology

[0002] Existing portable memory cards or USB flash drives are widely used in office, educational, and industrial control fields as portable data storage and transmission tools. Traditional USB flash drives mostly use rigid interfaces to connect directly to the storage device. While this meets basic data transmission needs, it presents a certain structural vulnerability in actual use. Firstly, during insertion and removal, if tilting or accidental impact occurs, the rigid interface is easily subjected to external force, causing bending, breakage, or loosening, leading to unstable data transmission or even interface failure. Secondly, when not in use, traditional USB flash drives often use simple plastic or metal covers for interface protection. These protective structures are prone to loosening and detachment during frequent opening and closing, and the protection method is mostly a single physical cover, failing to provide cushioning when subjected to external forces. Long-term use can easily cause interface wear or damage.

[0003] In addition, although some improved USB flash drives have added movable covers or sliding structures to cover the interface area when not in use, such structures usually only serve to prevent dust. They still lack effective buffering protection against tilting forces or external impacts during insertion and removal. Furthermore, the guiding positioning is not precise enough during opening and closing, which can easily lead to jamming or unstable positioning, affecting the user experience. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a foldable interface-protected mobile memory card. It can effectively protect the interface, provide buffering and shock absorption during insertion and removal, and also has a foldable storage function, so as to solve the shortcomings of traditional structures in terms of interface protection and impact resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foldable interface-protected mobile storage card includes a storage interface and a USB flash drive body. The storage interface and the USB flash drive body are fixedly connected by a flexible sleeve. A wire for electrically connecting the storage interface and the USB flash drive body is threaded through the inside of the flexible sleeve.

[0007] A cover is provided on the left end of the storage interface, and rotating arms are fixedly connected to the cover on both the front and rear sides of the storage interface. A dust cover is fixed on the right side of the cover and fitted onto the storage interface. Guide blocks are fixed on both the front and rear sides of the USB flash drive body. The guide blocks guide and restrict the rotation of the rotating arms when they move left and right. When the guide blocks are located at the rightmost end of the rotating arms, they do not restrict their rotation.

[0008] Furthermore, a first collar is fixed to the right end of the storage interface and fitted onto the outside of the flexible sleeve, and a first through hole is opened at the center of the right end face of the storage interface, and several evenly distributed first hanging posts are fixed to the edge of the right end face of the storage interface.

[0009] Furthermore, a second ring is fixed to the left end of the USB flash drive body and is fitted onto the outside of the flexible sleeve. A second wire hole is opened in the center of the left end face of the USB flash drive body. Several evenly distributed second hanging posts are fixed to the edge of the left end face of the USB flash drive body. A circular hanging platform is fixed to the end of the first hanging post and the second hanging post.

[0010] Furthermore, the flexible sleeve is a rubber sleeve, and both ends of the flexible sleeve are fixed with connecting edges extending inward, and uniformly arranged sleeve holes are opened on both the left and right connecting edges.

[0011] Furthermore, the guide block is designed as a long strip, with arc-shaped features on both the left and right ends. The guide block has slots on both the upper and lower sides, and a baffle is fixed to one end of the guide block that passes through the rotating arm.

[0012] Furthermore, a long guide groove is provided near the right end of the rotating arm, and protruding buckle ribs are fixed on the upper and lower side walls of the guide groove, and a rotating hole is provided at the right end of the guide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] To address the problem that rigid interfaces of existing mobile memory cards or USB flash drives are prone to bending, breakage, or loosening due to external impacts during insertion or removal, especially when subjected to tilting or accidental collisions, this invention incorporates a flexible sleeve structure between the storage interface and the USB flash drive body. Multiple independent insulated wires are threaded through the flexible sleeve for electrical connection. The two ends of the flexible sleeve are engaged with the first and second mounting posts via sleeve holes. Combined with the buffering properties of highly elastic and wear-resistant rubber, this effectively absorbs impacts and disperses stress when the interface area is subjected to external forces, significantly reducing the risk of interface breakage or deformation and improving the structural durability and lifespan of the interface.

[0015] To address the issues of traditional USB flash drives relying solely on simple caps or sliding covers for protection when not in use, which can easily lead to interface exposure due to loosening or wear, and lack of precise positioning and limiting, this invention incorporates a shielding cover, a dust cover, and a slidable and rotatable rotating arm at the storage interface. The rotating arm achieves smooth sliding through the cooperation of a guide block and a guide groove, and securely locks in the closed state through the engagement of a latching groove and a latching rib. When opened, it unlocks by rotating through a rotating hole at the end of the guide groove. This provides reliable physical protection and a sealing effect when not in use, and allows for quick and smooth switching to the open state when in use, ensuring both reliable interface protection and ease of operation.

[0016] While existing improved USB flash drives have added movable covers or sliding mechanisms, they still lack shock resistance while providing dust protection, and their guidance is not precise enough and they are prone to jamming during opening and closing. The protective structure of this utility model designs the guide block as a long strip with arcs at both ends, which, combined with the internal baffle, forms a physical limit. This reduces sliding friction resistance and ensures smooth operation of the rotating arm in the guide path, avoiding jamming or dislocation caused by inaccurate positioning or excessive sliding. At the same time, the buffering characteristics of the flexible sleeve ensure that the interface remains stable when subjected to external impact, thus taking into account dust protection, shock resistance, and smooth operation.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] Example 1:

[0027] like Figure 1As shown, the foldable interface-protected mobile storage card includes a storage interface 3 and a USB flash drive body 5. The storage interface 3 and the USB flash drive body 5 are fixedly connected by a flexible sleeve 4. A wire for electrically connecting the storage interface 3 and the USB flash drive body 5 is threaded through the inner side of the flexible sleeve 4. The flexible sleeve 4 is made of highly elastic rubber material, which provides cushioning and shock absorption when connected to withstand impacts caused by accidental collisions, tilting during insertion / removal, or lateral forces during use, thereby reducing the risk of breakage or bending that traditional rigid interfaces are prone to under similar conditions. A cover 1 is provided at the left end of the storage interface 3, and covers 1 are provided on both the front and rear sides of the storage interface 3. The rotating arm 7 is fixedly connected, and a dust cover 2 is fixedly fitted on the right side of the cover 1 to the storage interface 3. When the storage interface 3 is not in use, the dust cover 2 can effectively prevent dust, moisture and small particles from entering the interface area, improving the durability of the interface. Guide blocks 6 are fixed on both the front and rear sides of the USB flash drive body 5. The guide blocks 6 guide and restrict the rotation of the rotating arm 7 when it moves left and right, ensuring that the position of the rotating arm 7 is accurate during the opening and closing process, and avoiding jamming or loosening of the protective structure due to inaccurate positioning. When the guide block 6 is located at the rightmost end of the rotating arm 7, it does not restrict its rotation, so that the user can rotate the cover 1 to the fully open state for data transmission operations.

[0028] like Figure 2 As shown, a first collar 31 is fixed to the right end of the storage interface 3 and fitted onto the outside of the flexible sleeve 4. The first collar 31 is used to cooperate with the outer wall of the port of the flexible sleeve 4 to achieve stable mechanical fixation, and at the same time form a transition connection between the interface end and the buffer structure to avoid damage to the electrical contacts due to direct force. A first wire hole 32 is opened in the center of the right end face of the storage interface 3. The first wire hole 32 is used to accommodate the wires to pass through and to be soldered to the internal circuit board to achieve a reliable connection for data transmission and power supply. Several evenly distributed first hanging posts 33 are fixed to the edge of the right end face of the storage interface 3. After the first hanging posts 33 are fitted onto the connecting edge 42 of the flexible sleeve 4 through the sleeve hole 41, they provide stable limiting and fixing functions to prevent the flexible sleeve 4 from displacing or falling off under the action of external force.

[0029] like Figure 3As shown, a second collar 51 is fixed to the left end of the USB flash drive body 5, which is sleeved on the outside of the flexible sleeve 4. The second collar 51 cooperates with the first collar 31 to form a complete protective buffer link at both ends of the flexible sleeve 4 in the connected state, further improving the impact resistance of the interface area. A second wire hole 52 is opened in the center of the left end face of the USB flash drive body 5. The second wire hole 52 corresponds to the first wire hole 32, which facilitates the wire to pass through and connect to the storage control chip inside the USB flash drive body 5, so as to realize high-speed and stable data interaction. Several evenly distributed second hanging posts 53 are fixed on the edge of the left end face of the USB flash drive body 5. The second hanging posts 53 are similar in structure to the first hanging posts 33. A circular hanging platform is fixed at the end of each post. After the circular hanging platform is inserted into the sleeve hole 41 of the flexible sleeve 4, it forms a reliable mechanical limit to ensure the firm connection between the buffer structure and the two ends of the body.

[0030] like Figure 4 As shown, the flexible sleeve 4 is a rubber sleeve. The material of the flexible sleeve 4 has high elasticity and wear resistance, which can maintain the deformation recovery ability during long-term use and provide flexible buffer when the interface area is subjected to force. Both ends of the flexible sleeve 4 are fixed with connecting edges 42 extending inward. The presence of connecting edges 42 makes the flexible sleeve 4 form a stable end snap-fit ​​structure with the first collar 31 and the second collar 51. The connecting edges 42 on both the left and right sides are provided with uniformly arranged sleeve holes 41. The sleeve holes 41 are used to engage with the first hanging post 33 and the second hanging post 53 to prevent the buffer sleeve from slipping when subjected to external force, while maintaining the stable layout of the internal wires and the reliability of the electrical connection.

[0031] like Figure 5 As shown, the guide block 6 is elongated, and both ends of the guide block 6 are provided with arc-shaped structures to facilitate smooth guidance of the rotating arm 7 when it slides along it, reducing frictional resistance. The guide block 6 has a locking groove 62 on both the upper and lower sides, which is used to reliably engage with the locking rib 71 on the rotating arm 7. When the protective structure is closed, it can effectively limit the accidental movement of the rotating arm 7. A baffle 61 is fixed to one end of the guide block 6 that passes through the rotating arm 7. When the baffle 61 moves to the end of the guide groove 72, it forms a physical limit to prevent the rotating arm 7 from sliding out excessively and causing the protection to fail.

[0032] like Figure 6As shown, a long guide groove 72 is provided near the right end of the rotating arm 7. The shape of the guide groove 72 matches the shape of the guide block 6, ensuring that the rotating arm 7 moves smoothly along the guide block 6. The upper and lower side walls of the guide groove 72 are fixed with protruding buckle ribs 71. When the buckle ribs 71 are in the protective closed state, they are engaged with the buckle grooves 62 on the guide block 6, thereby stably locking the position of the rotating arm 7 and preventing it from being released due to vibration or accidental contact. A rotating hole 73 is provided at the right end of the guide groove 72. When the guide block 6 moves to this position, the rotating arm 7 can be unlocked in the horizontal direction and rotated freely, so that the cover 1 can be completely removed from the interface area for the user to perform plugging and unplugging operations. At the same time, when not in use, it can be reversed to close and protect the interface, thereby improving the service life and damage resistance of the storage interface 3.

[0033] Example 2:

[0034] See Figures 1-6 A foldable interface-protected mobile storage card includes a storage interface 3, a USB flash drive body 5, a flexible sleeve 4, a shielding cover 1, a dust cover 2, a rotating arm 7, a guide block 6, a first collar 31, a second collar 51, a first wire hole 32, a second wire hole 52, a first hanging post 33, a second hanging post 53, a circular hanging platform, a connecting edge 42, a sleeve hole 41, a baffle 61, a buckle groove 62, a guide groove 72, a buckle rib 71, and a rotating hole 73. The right end of the storage interface 3 is fixedly connected to one end of the flexible sleeve 4 via the first collar 31, and the left end of the USB flash drive body 5 is fixedly connected to the other end of the flexible sleeve 4 via the second collar 51. Multiple independently insulated wires are evenly arranged inside the flexible sleeve 4. The front end of each wire passes through the first wire hole 32 and is electrically connected to a metal contact piece inside the storage interface 3. The other end of each wire passes through the second wire hole 52 and is soldered to a storage control circuit board inside the USB flash drive body 5, thereby realizing data transmission and power supply functions. The flexible sleeve 4 is made of highly elastic and wear-resistant rubber. The connecting edges 42 at both ends are respectively fitted onto the first hanging post 33 and the second hanging post 53 through the sleeve holes 41. The ends of the first hanging post 33 and the second hanging post 53 are fixed with circular hanging platforms to prevent the connecting edges 42 from falling off under external force. This structure enables the flexible sleeve 4 to absorb and disperse the impact force from the interface direction during insertion, removal or collision, reducing the risk of breakage.

[0035] In the protective structure, a cover 1 is fixed to the left end of the storage interface 3. The two sides of the cover 1 are connected to the front and rear sides of the storage interface 3 through rotating arms 7. The right end of the rotating arm 7 is fixedly connected to the dust cover 2. The dust cover 2 is made of flexible plastic and its internal dimensions match the shape of the storage interface 3. It is used to cover the storage interface 3 to form a sealed protection when the device is not in use. Guide blocks 6 are fixed to the front and rear sides of the USB flash drive body 5. The surface of the guide block 6 is provided with a buckle groove 62 and a baffle 61 runs through it. The baffle 61 is used to form a physical limit when the rotating arm 7 moves to the limit position to prevent excessive sliding and dislocation. The rotating arm 7 is provided with a guide groove 72 inside. Buckle ribs 71 are fixed on the upper and lower side walls of the guide groove 72. Buckle ribs 71 can engage with buckle grooves 62 on the guide block 6 to ensure the stability of the protective closed state. The right end of the guide groove 72 is provided with a rotating hole 73. When the guide block 6 moves to this position, the rotating arm 7 can rotate around the connection point to realize the switching between the protective state and the use state.

[0036] Its operation is as follows: When not in use, the rotating arm 7 is in the closed position on the left, the dust cover 2 completely covers the storage interface 3, and the buckle 71 and the buckle groove 62 are tightly fastened to form a lock, preventing the interface from being exposed due to vibration or friction; when needed, the user holds both sides of the cover 1 and slides the rotating arm 7 parallel to the left. At this time, the guide block 6 slides along the guide groove 72, and the baffle 61 enters the range of the rotating hole 73 at the end of the slide, so that the rotating arm 7 is released from the horizontal limit. The user can then rotate the rotating arm 7 together with the cover 1 to the fully open position on the right, exposing the storage interface 3 for insertion and removal operations; during the insertion and removal process, the wires inside the flexible sleeve 4 maintain a stable electrical connection and rely on the elastic properties of the rubber material to absorb external impacts or skew forces, avoiding damage to the rigid interface caused by external forces; after use, the user rotates the rotating arm 7 in the opposite direction to the left and pushes it to the closed position along the guide groove 72. The dust cover 2 is re-covered on the storage interface 3, and the buckle 71 and the buckle groove 62 are fastened again, completing the protective storage process.

[0037] Through the above operation process, the storage interface 3 can be effectively protected against dust and shock when not in use, and has a flexible folding and rotating structure during use. The overall durability and damage resistance are improved by the buffering effect of the flexible sleeve 4, which solves the problems of easy breakage, lack of buffering and insufficient protection of traditional mobile storage device interfaces.

[0038] The working principle of this utility model is as follows:

[0039] During the state switching process, the storage interface 3 is first connected to the USB flash drive body 5 through the flexible sleeve 4. Multiple independent insulated wires are evenly arranged inside the flexible sleeve 4. The front end passes through the first wire hole 32 and is electrically connected to the metal contact piece inside the storage interface 3. The rear end passes through the second wire hole 52 and is soldered to the storage control circuit board inside the USB flash drive body 5, thereby realizing data transmission and power supply functions. The two ends of the flexible sleeve 4 are connected to the first hanging post 33 and the second hanging post 53 respectively through the sleeve hole 41, and are limited by the circular hanging platform at the end of the hanging post to ensure that the buffer structure is stable and reliable. When plugging or unplugging or collision, the elasticity of the rubber material can absorb the impact of external force and reduce the risk of interface breakage or deformation.

[0040] During interface protection operation, when the USB flash drive is not in use, the cover 1 is fixed to the front end of the storage interface 3 by the rotating arm 7, and the dust cover 2 completely covers the outside of the storage interface 3 to prevent dust, moisture and small particles from entering the interface area; the two ends of the rotating arm 7 cooperate with the guide block 6, and the guide block 6 engages with the buckle rib 71 of the guide groove 72 inside the rotating arm 7 through the buckle groove 62 to achieve stable locking in the closed state and prevent the protective structure from being accidentally loosened during carrying or moving.

[0041] When in use, the user pushes the rotating arm 7 to the left along the direction of the guide block 6, causing the guide block 6 to slide in the guide groove 72. When the baffle 61 moves to the end of the guide groove 72 and enters the position of the rotating hole 73, the horizontal limit of the rotating arm 7 is released. At this time, it can be rotated around the connection point to turn the shielding cover 1 and the dust cover 2 to the right side, thereby fully exposing the storage interface 3 for insertion and removal. During data transmission, the buffering effect of the flexible sleeve 4 can absorb stress when the interface is subjected to tilted insertion or accidental impact, ensuring stable wire connection and reliable signal transmission.

[0042] When closing the storage, rotate the rotating arm 7 in the opposite direction to the left position and push it to the right along the guide groove 72 so that the dust cover 2 is put back on the storage interface 3. At the same time, the buckle 71 and the buckle groove 62 are engaged again to achieve protection and locking. At this time, the interface area is sealed and protected to prevent dust and external force damage, and the folding storage is completed.

[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
