Description

Technical Field

[0001] This utility model relates to the field of flash memory card technology, specifically to a flash memory card. Background Technology

[0002] Flash memory cards, as non-volatile storage devices based on flash memory technology, play a crucial role in modern electronic devices. Their working principle is based on floating-gate transistors within the flash memory chip, controlling the charge of the floating gate to achieve data storage and retrieval. Compared to traditional storage media, flash memory cards offer significant advantages such as small size, light weight, fast read / write speeds, strong shock resistance, and the ability to maintain data storage without an external power supply. These characteristics make flash memory cards widely used in various mobile devices such as digital cameras, smartphones, tablets, and portable music players, serving as a key carrier for data storage and exchange.

[0003] However, current flash memory cards on the market still have some problems that urgently need to be solved. Firstly, when not in use, the gold fingers of the flash memory card are usually directly exposed. As a key conductive component connecting the memory card to the device, direct exposure makes them susceptible to scratches from external forces. These damages can severely affect the stability of the electrical connection between the gold fingers and the device interface, leading to data transmission failures or even rendering the memory card unusable. Secondly, when users need to use the card on devices that do not support native flash memory card interfaces, they often need to purchase a compatible adapter. This not only increases the user's cost and the burden of carrying the device, but may also cause data transmission instability or recognition failures due to compatibility issues between the adapter and the memory card or target device, greatly reducing the user experience and limiting the ease of use and application range of flash memory cards.

[0004] Therefore, this application provides a flash memory card. Utility Model Content

[0005] The purpose of this invention is to provide a flash memory card to solve the problems mentioned in the background art, such as the easy damage to the gold fingers of flash memory cards and the need to purchase a matching adapter separately.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flash memory card, comprising: The flash memory card body has a gold finger soldered to one side of its lower wall. The protective mechanism is slidably connected to the outer wall of the flash memory card body. A conversion head is hinged to the lower end of the protective mechanism. A second gold finger, which is compatible with the first gold finger, is welded to the outer wall of the left side of the conversion head. A third gold finger is welded to the outer wall of the upper end of the conversion head.

[0007] Based on the above technical solution and the usage of flash memory cards, the specific form and operation method of the flash memory card are as follows: When the flash memory card is in use, the protective mechanism is located on the side of the flash memory card body away from the gold fingers. By holding the protective mechanism, the flash memory card body can be inserted into the device to use flash storage. When the flash memory card is not in use, by pulling the protective mechanism, the protective mechanism is moved to the side of the flash memory card body close to the gold finger. At this time, the conversion head at the lower end of the protective mechanism moves directly under the gold finger, thereby blocking the gold finger and effectively preventing the gold finger from being scratched by external force. When the flash memory card is in the conversion state, the protective mechanism is pulled to move the protective mechanism to the side of the flash memory card body close to the gold fingers. Then, the conversion head is rotated to rotate the second gold finger on one side of the conversion head to contact the first gold finger, thereby connecting the flash memory card body to the conversion head. The conversion is achieved through the third gold finger on the other side of the conversion head.

[0008] Preferably, the upper surface of the protective mechanism has two symmetrically arranged mounting slots, and each mounting slot has a fixed column slidably connected inside.

[0009] By using the above technical solution, the lower end of the fixing post is pressed tightly against the upper surface of the flash memory card body, thereby fixing the protective mechanism at any position on the outside of the flash memory card body.

[0010] Preferably, the outer walls on both sides of the fixing column are provided with symmetrically arranged locking grooves, and symmetrically arranged spring pieces are fixedly installed on both sides of the mounting groove by bolts.

[0011] Using the above technical solution, the position of the fixing post is fixed by the spring and locking groove. At the same time, when the locking groove at the upper end of the outer wall of the fixing post engages with the spring, the lower end of the fixing post presses against the upper wall of the flash memory card body, so that the flash memory card body and the protective mechanism are in a locked state. When the locking groove at the lower end of the outer wall of the fixing post engages with the spring, the lower end of the fixing post no longer exerts pressure on the upper wall of the flash memory card body, so that the flash memory card body and the protective mechanism are in an unlocked state, and the position of the protective mechanism can be changed at will.

[0012] Preferably, the upper surface of the flash memory card body has openings corresponding to the position and number of fixing posts.

[0013] By adopting the above technical solution, the protective mechanism always moves in a straight line.

[0014] Preferably, the converter head has a circuit board inside, and the output terminal of the circuit board is electrically connected to the second gold finger and the third gold finger, respectively.

[0015] Preferably, the outer walls on both sides of the protective mechanism are integrally provided with anti-slip protrusions.

[0016] The above technical solution improves the friction on the outside of the protective mechanism.

[0017] Preferably, when the converter head is in a horizontal state, two sides of its outer gold fingers face the protective mechanism, and three sides of its gold fingers face the flash memory card body.

[0018] By adopting the above technical solution, when the converter head is not in use, the second and third gold fingers are blocked by the protective mechanism and the flash memory card body, respectively, which can effectively prevent the second and third gold fingers from being scratched.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This flash memory card: 1. Through the coordinated design of the protective mechanism and the built-in adapter, the problem of exposed and vulnerable gold fingers is completely solved. When not in use, pulling the protective mechanism to the gold finger side allows the adapter to naturally droop and shield gold finger one. Simultaneously, gold fingers two and three of the adapter itself are also shielded by the protective mechanism and the memory card body, forming comprehensive protection. This design effectively prevents scratches on the gold fingers from external forces, ensures a stable electrical connection between the gold fingers and the device interface, reduces data transmission failures, and significantly extends the overall lifespan of the memory card.

[0020] 2. The adapter and protective mechanism are integrated into one design, eliminating the need for users to purchase separate adapter accessories and significantly reducing usage costs. Simultaneously, the adapter can rotate around the hinge point, precisely aligning with the memory card's gold fingers one via gold finger two, and then using gold finger three to adapt to different interface devices, ensuring compatibility with mainstream interface types. This avoids recognition failures or unstable transmissions caused by compatibility issues with external adapters, allowing for more flexible switching between various devices.

[0021] 3. The sliding locking mechanism of the protective structure is simple to operate; simply press the fixing post to unlock and lock. The anti-slip protrusions allow users to easily pull and adjust the position without complicated steps. Whether exposing the gold fingers during normal use, protecting and storing it when not in use, or converting the interface to adapt to different devices, the state can be quickly switched with a simple operation, without the need for tools. This convenient design allows the memory card to easily adapt to various scenarios such as daily storage, carrying it when traveling, and data exchange with multiple devices, greatly improving the user experience.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Example: Please see Figure 1-5 This utility model provides a technical solution: a flash memory card, comprising: The flash memory card body 10 serves as the data storage core of the entire device, encapsulating key components for data storage and processing, enabling stable data writing, reading, and saving. Structurally, a gold finger 11 is soldered to one side of the lower wall of the flash memory card body 10. This gold finger 11 is a crucial conductive component connecting the memory card to external devices, and its pin layout matches conventional device interfaces, ensuring a smooth electrical connection and facilitating data transmission. Simultaneously, to facilitate the sliding of the protective mechanism 20, a guide groove 12 is formed on the upper surface of the flash memory card body 10, corresponding to the position and number of the fixing posts 22. The length of the guide groove 12 matches the sliding stroke of the protective mechanism 20, and its width matches the lower end dimension of the fixing posts 22, precisely limiting the sliding direction of the protective mechanism 20. As a crucial component ensuring the durability and compatibility of the memory card, the protective mechanism 20 employs a frame structure that conforms to the shape of the flash memory card body 10. It can slide tightly and flexibly onto the outer wall of the flash memory card body 10, ensuring uninterrupted normal use of the memory card while providing comprehensive protection when needed. Both sides of the protective mechanism 20 are integrally equipped with anti-slip protrusions 28. These protrusions 28 feature an uneven surface structure, effectively increasing the friction between the user's hand and the protective mechanism 20. When the user needs to pull the protective mechanism 20 to adjust its position, the anti-slip protrusions 28 prevent hand slippage, allowing for easier and more stable application of force, improving operational convenience and safety. The anti-slip effect is particularly noticeable when hands are sweaty or gloves are worn. The upper surface of the protective mechanism 20 has two symmetrically arranged mounting slots 21. The position and size of the mounting slots 21 are precisely designed to ensure that they can provide stable installation and sliding space for the fixing posts 22. The fixing posts 22 are slidably connected inside each mounting slot 21. The fixing posts 22 can move up and down within the mounting slots 21. The fixing and unlocking of the protective mechanism 20 is achieved by the contact and separation between the lower end of the fixing post 22 and the upper surface of the flash memory card body 10. Specifically, when the protective mechanism 20 needs to be fixed, the fixing post 22 is pressed downwards, causing its lower end to press tightly against the upper surface of the flash memory card body 10, using the friction between them to restrict the sliding of the protective mechanism 20. When the position of the protective mechanism 20 needs to be adjusted, the fixing post 22 is pulled upwards, causing its lower end to detach from the upper surface of the flash memory card body 10. At this time, the protective mechanism 20 can slide freely along the outer wall of the memory card body 10. To further enhance the stability of the fixed post 22 in fixing the position of the protective mechanism 20, symmetrical locking grooves 24 are provided on both outer walls of the fixed post 22. The locking grooves 24 have an arc-shaped structure and can form a stable engagement relationship with the spring pieces 23. At the same time, symmetrical spring pieces 23 are fixedly installed on both sides of the mounting groove 21 by bolts. The spring pieces 23 are made of metal with good elasticity and tend to move towards the center of the mounting groove 21 in their natural state. The position of the fixing post 22 can be precisely fixed by the cooperation of the spring piece 23 and the locking groove 24: when the outer wall of the fixing post 22 is located at the upper locking groove 24 and the spring piece 23 is engaged, the spring piece 23 is inserted into the upper locking groove 24, which forms downward pressure on the fixing post 22, so that the lower end of the fixing post 22 is tightly pressed against the upper wall of the flash memory card body 10, thereby keeping the flash memory card body 10 and the protective mechanism 20 in a stable locked state, effectively preventing the protective mechanism 20 from accidentally sliding during use; when the outer wall of the fixing post 22 is located at the lower locking groove 24 and the spring piece 23 is engaged, the spring piece 23 is inserted into the lower locking groove 24, at which time the position of the fixing post 22 moves upward, and the lower end no longer exerts pressure on the upper wall of the flash memory card body 10, so that the flash memory card body 10 and the protective mechanism 20 are in an unlocked state, and the user can easily change the position of the protective mechanism 20; The lower end of the protective mechanism 20 is connected to the adapter head 25 via a hinge structure. The hinge design allows the adapter head 25 to rotate flexibly around the hinge point, providing a structural basis for switching between different usage states. As the core component of the interface conversion, the adapter head 25 has a second gold finger 26 welded to its left outer wall, which is compatible with the first gold finger 11. The number and arrangement of the pins of the second gold finger 26 are completely identical to those of the first gold finger 11, ensuring stable electrical conduction when the two are in contact. At the same time, a third gold finger 27 is welded to the upper outer wall of the adapter head 25. The third gold finger 27 adopts a universal interface specification and can be adapted to various external devices with different interface types, such as the common Type-C interface and USB-A interface, greatly expanding the applicability of memory cards. In addition, the converter 25 contains a signal conversion circuit board. This circuit board is the core component of the converter 25, enabling its interface conversion function. Its output and input terminals are electrically connected to the second gold finger 26 and the third gold finger 27 via wires, respectively. The circuit board integrates key components such as signal conversion chips and filtering elements, enabling precise conversion of the signal transmitted by the first gold finger 11, ensuring it is compatible with the interface protocol of the device connected to the third gold finger 27. This guarantees the stability and compatibility of data transmission between different devices, preventing signal loss and transmission interruptions. It is worth noting that when the adapter 25 is in a horizontal position, its outer gold fingers 26 face the protective mechanism 20, and its outer gold fingers 27 face the flash memory card body 10. This structural design ensures that when the adapter 25 is not in use, the gold fingers 26 are shielded by the inner wall of the protective mechanism 20, and the gold fingers 27 are shielded by the outer wall of the flash memory card body 10, preventing both from being directly exposed and effectively preventing scratches to the gold fingers 26 and 27 from external forces.

[0026] Working principle: No interface conversion is required under normal use.

[0027] Unlocking the protection mechanism: Press the fixing post 22 to disengage the spring piece 23 from the upper locking groove 24 of the fixing post and slide it into the lower locking groove 24. At this time, the lower end of the fixing post disengages from the guide groove 12 of the memory card body, and the protection mechanism 20 is in the unlocked state. Sliding protection mechanism: Pull the protection mechanism 20 along the guide slide 12 to move it to the side of the flash memory card body 10 away from the gold finger 11; Locking and Use: Press the fixing post 22 again, the spring piece 23 will be inserted into the upper locking groove 24 of the fixing post, and the lower end of the fixing post will press against the inner wall of the guide slide 12 to lock the position of the protective mechanism; at this time, the gold finger 11 is fully exposed, and the memory card can be inserted into the device interface by holding the anti-slip protrusion 28 of the protective mechanism.

[0028] Gold finger protection when not in use

[0029] After unlocking the protective mechanism, pull the protective mechanism 20 in the opposite direction to move it to the side closer to the gold finger 11; At this time, the conversion head 25 at the lower end of the protective mechanism naturally hangs down to directly below the gold finger 11, completely blocking the gold finger 11; Press the fixing post 22 to lock the protective mechanism and prevent slippage, thus achieving dustproof and scratch-proof protection for the gold finger 11.

[0030] The interface is used to adapt to different devices.

[0031] When not in use, move the protective mechanism 20 to the side of the gold finger 11 and lock it; Rotate the converter head 25 around the hinge point to a vertical position so that the gold fingers 26 of the converter head are fully engaged with the gold fingers 11 of the memory card body, and the signal is conducted through the circuit board. At this point, the gold fingers 327 of the adapter are exposed, allowing direct insertion into devices with compatible interface types, such as Type-C computers or USB-A flash drives, without the need for an additional adapter.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
