Description

Technical Field

[0001] This utility model relates to the field of storage product structure, specifically to a high-speed flash drive structure. Background Technology

[0002] Currently, USB Type-A flash drives that support the USB 3.1 Gen2 protocol specification use traditional USB Type-A connectors. The plastic core occupies a large space, and the controller chip, flash memory chip, and other circuit components of USB 3.1 Gen2 are more numerous and larger in size. This results in a larger circuit board size, which, combined with the equally large USB Type-A connector, prevents the entire flash drive from being miniaturized. In addition, flash drives have a transfer rate of up to 500MB / s. The performance improvement results in greater power consumption and heat generation. Common flash drives use metal casings, but even though metal casings are small and thin, they are still noticeably hot to the touch, and the burning sensation affects the user experience.

[0027] Reference Figure 1 , Figure 2A high-speed flash drive structure includes a circuit board module 1, a metal tube 2, a heat sink 3, and a U-shaped plastic component 4. The circuit board module 1 is the core component of the high-speed flash drive, responsible for circuit connections, signal transmission, and processing. The circuit board module 1 is installed inside the metal tube 2, providing protection and support to prevent damage. The heat sink 3 is located outside the metal tube 2, allowing heat generated during operation to dissipate through the metal tube 2 and the heat sink 3, ensuring stable operation of the flash drive. The U-shaped plastic component 4 engages with both sides of the metal tube 2 and the heat sink 3, featuring a lightweight U-shaped design. This design also allows for more direct air contact between the metal tube 2 and the heat sink 3, improving heat dissipation efficiency. The plastic material also facilitates easy insertion and removal of the flash drive. Both the heat sink 3 and the U-shaped plastic component 4 are located at the rear end of the metal tube 2, allowing the front end of the metal tube 2 to combine with the circuit board module 1 to form a USB TYPE. Connector A is small in size and meets usage requirements, making it convenient for connecting flash drives to other devices.

[0028] Reference Figure 3 , Figure 4 In an embodiment of this utility model, the circuit board module 1 includes a circuit board 11, a 5P onboard connector 12, and a controller chip 13. The 5P onboard connector 12 and the controller chip 13 are connected to the circuit board 11. The 5P onboard connector 12 is located at the front end of the circuit board 11 and forms a USB TYPEA connector with the front end of the metal tube 2, which facilitates the connection between the flash drive and external devices. The controller chip 13 is located at the rear end of the circuit board 11 and realizes functions such as signal transmission of the flash drive.

[0029] Specifically, the 5P board connector 12 is provided with a first limiting recess 121, and the top of the metal tube 2 is provided with a second limiting recess 21. The second limiting recess 21 is located inside the first limiting recess 121. By fixing the circuit board module 1 through the limiting stamping recess, it is beneficial to improve the firmness of the 5P board connector 12 and further enhance the stability of the circuit board module 1 inside the metal tube 2.

[0030] Specifically, the front end of the metal tube 2 is provided with a limiting groove 22, and the front ends of the circuit board 11 are provided with limiting plate edges 111 on both sides. The limiting plate edges 111 are engaged in the limiting groove 22 to realize the upper and lower limiting fixation of the circuit board 1 in the metal tube 2. The front end of the circuit board 11 is provided with a slanted guide edge 112 to facilitate the insertion and removal of the flash drive.

[0031] Specifically, the top of the metal tube 2 is also provided with a heat dissipation hole 23, which is located above the controller chip 13. The heat dissipation component 3 is located outside the heat dissipation hole 23. By contacting the heat dissipation hole 23 area on the metal tube 2, the heat generated by the controller chip 13 is quickly dissipated, thereby achieving effective heat dissipation.

[0032] Reference Figure 3 , Figure 5 In an embodiment of this utility model, the heat sink 3 includes a cover plate 31 and fin protrusions 32. The cover plate 31 is provided with a plurality of fin protrusions 32, which increases the heat dissipation area, allowing heat to be transferred more effectively from the controller chip 13 to the air. The spaced arrangement of the fin protrusions 32 facilitates airflow and further improves heat dissipation efficiency. The lower end of the cover plate 31 is provided with a positioning pin 33, and the top of the metal tube 2 is provided with a connecting hole 24. The positioning pin 33 is disposed in the connecting hole 24 to precisely position and fix the heat sink 3 on the metal tube 2. At the same time, the heat sink 3 covers the heat dissipation hole 23 area above the controller chip 13, and the cover plate 31 provides a large heat dissipation area, enhancing the heat dissipation effect.

[0033] Reference Figure 3 , Figure 4 , Figure 6 In an embodiment of this utility model, the inner wall of the U-shaped plastic part 4 is provided with an installation groove 41, and the metal tube 2 and the cover plate 31 are snapped into the installation groove 41, so that the U-shaped plastic part 4 can stably wrap and fix the metal tube 2 and the cover plate 31 of the heat dissipation component 3 to form an integral structure. The U-shaped plastic part 4 can play a good role in preventing scalding and slipping.

[0034] Specifically, the mounting groove 41 has slots 42 on both sides, and the metal tube 2 has wings 25 on both sides. The wings 25 are disposed within the slots 42, forming a secure snap-fit ​​connection between the U-shaped plastic part 4, the metal tube 2, and the heat sink 3, ensuring the structural integrity and stability of the entire flash drive. Furthermore, the recesses, holes, and wings on the metal tube 2 can be manufactured using a bending and stamping process. This processing technology is mature, low-cost, and ensures the shape and dimensional accuracy of the flash drive.

[0035] Specifically, the U-shaped plastic component 4 is designed with a narrower front and wider back, conforming to ergonomic principles and making it more comfortable for users to hold the device. Furthermore, the outer side of the U-shaped plastic component 4 has multiple anti-slip protrusions 43, increasing friction when the user holds the flash drive and preventing it from slipping or sliding, thus improving safety. In addition, the tail of the U-shaped plastic component 4 has a lanyard hole 44, and the lanyard hole is triangular in shape, forming an aesthetic design with the overall shape of the flash drive, enhancing its overall appearance. It also allows users to easily hang the flash drive around their neck or fix it in a certain position for convenient carrying and use.

[0036] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments.
