Technical Field
[0001] This utility model relates to the field of hard disk technology, and in particular to a high-efficiency heat dissipation portable solid-state drive. Background Technology
[0002] In today's digital age, data is exploding, particularly in the gaming and video production industries. As game graphics become increasingly sophisticated and storylines richer, game file sizes are also growing exponentially. Similarly, the widespread adoption of high-definition and even ultra-high-definition video recording technologies has resulted in massive amounts of video data. The demand for storage capacity is constantly rising to accommodate these enormous amounts of game and video data.
[0003] Meanwhile, data transfer rates are rapidly increasing. Against this backdrop, solid-state drives (SSDs), with their significant advantages over traditional hard disk drives (HDDs), have gradually become one of the mainstream choices in the storage field. SSDs use flash memory chips as the storage medium, eliminating the mechanical structure of traditional HDDs, thus achieving a huge breakthrough in data transfer speeds. Their high transfer rates can meet users' needs for quickly copying and loading large files.
[0004] Because of these characteristics of SSDs, users have begun to directly store large files such as large drawings, massive game installation files, or long high-definition videos on external SSDs. This approach brings great convenience; as long as the computer can recognize the external SSD, users can easily run large files stored on it on different computers without having to store the same large files on each computer repeatedly. This effectively saves local storage space on each computer and facilitates data sharing and use across multiple devices.
[0005] However, direct use of portable SSDs has also revealed some problems that urgently need to be addressed. When users run large files directly on portable SSDs, the SSDs often need to maintain high-speed operation for extended periods. For example, when running demanding AAA games, the game constantly reads and writes data to the portable SSD, causing it to operate under high load for extended periods. Prolonged high-speed operation generates a significant amount of heat inside the portable SSD, and if this heat cannot be dissipated in time, it will severely impact the performance and lifespan of the portable SSD.
[0006] To ensure that portable SSDs can maintain stable high-speed operation for extended periods, a common practice is to incorporate a heat dissipation structure. Most existing heat dissipation structures utilize a metal casing for heat conduction. The metal casing can absorb some of the heat generated inside the portable SSD and conduct it to the external environment. However, this method of heat dissipation relying solely on a metal casing has significant limitations.
[0007] On the one hand, the heat dissipation efficiency of a metal casing is relatively limited. When a portable SSD is under prolonged high-intensity operation, the metal casing alone may not be able to dissipate heat effectively and in a timely manner, leading to excessively high internal temperatures. On the other hand, due to the inherent structural limitations of portable SSDs, it is always difficult to implement more efficient water-cooling or air-cooling solutions in a suitable way. Portable SSDs are typically small and compact, with limited internal space, making it difficult to accommodate complex water-cooling or air-cooling components. Moreover, adding these cooling components may also affect the portability of the portable SSD, which contradicts the original intention of portable SSDs to be easy to carry and use anytime, anywhere.
[0008] In conclusion, given the increasing demand for high-capacity, high-speed storage devices in the current data-driven era, the heat dissipation problem faced by portable solid-state drives during use has become a key factor restricting their performance improvement and continuous stable operation, urgently requiring an improved technical solution to effectively address this issue. Utility Model Content
[0009] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.
[0010] A high-efficiency heat-dissipating portable solid-state drive includes a hard drive body with a metal casing and a main circuit board disposed inside the metal casing. The main circuit board has a data transmission interface extending from the front of the metal casing. It also includes a heat dissipation body, which includes a fan bracket, a cooling fan mounted on the fan bracket, and power supply wires electrically connected between the cooling fan and the main circuit board. At each of the four corners of the fan bracket, a swing arm mounting base extends downwards, and a swing arm support is hinged to the swing arm mounting base. At each of the four corners of the metal casing, there is a docking port for engaging the swing arm mounting base. Sliding grooves are provided on both sides of the metal casing, with the two ends of the sliding grooves engaging with the docking ports. Sliding blocks, which can slide to abut against the docking ports, are slidably connected at the front and rear positions within the sliding grooves. The sliding blocks are hinged to the swing arm support, and a compression spring is provided between the sliding blocks and the sliding groove to drive the sliding blocks to abut against the docking ports.
[0011] Preferably, the main circuit board integrates a main control chip, a flash memory chip, a cache chip, and a power management chip. The flash memory chip, cache chip, power management chip, data transmission interface, and power supply wires are all electrically connected to the main control chip.
[0012] Preferably, the swing arm is configured such that when the swing arm fixing seat is mated with the mating socket, the end of the swing arm hinged to the swing arm fixing seat is deeper in the mating socket than the end of the swing arm hinged to the sliding block is in the mating socket.
[0013] Preferably, the swing arm is configured such that when the sliding block abuts the docking port, the swing arm is in an inclined state, so that when the heat dissipation body is pressed down, it can generate a component force on the sliding block that overcomes the compression spring.
[0014] Preferably, a concave-convex structure is provided between the inner wall of the swing arm fixing seat and the docking port, so that the swing arm fixing seat can be locked in place by the concave-convex structure after it is docked with the docking port.
[0015] Preferably, there are blocking strips on both sides of the sliding groove that abut against the upper end of the sliding block, and the two blocking strips are spaced apart so that the swing rod can move between the two blocking strips.
[0016] Preferably, both the sliding block and the swing arm support are provided with hinge seats, and the sliding block and the swing arm support are respectively hinged to both ends of the swing rod through the hinge seats.
[0017] Preferably, the sliding block is further provided with a spring rod, a compression spring is sleeved on the spring rod, and a blocking block is provided in the middle of the sliding groove, with the other end of the compression spring engaging with the blocking block.
[0018] Preferably, a heat dissipation cover is provided at the upper end of the metal casing, and heat dissipation fins are provided on the heat dissipation cover facing the cooling fan.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] By incorporating a heatsink on the hard drive body, and cleverly connecting it to the hard drive body using four corners with a swing-out support, the hard drive body and heatsink can be closed together when not in use for easy portability. When the hard drive body is under high load, the heatsink is raised and held in place, maintaining a certain distance between it and the hard drive body. When the cooling fan on the heatsink operates, it blows cool air onto the hard drive body to dissipate heat. Furthermore, the raised heatsink significantly improves airflow, allowing the cooling fan to work more efficiently on the hard drive body, resulting in more effective heat dissipation.
[0021] Structurally, the design employs a swing arm, a swing arm mounting base, a sliding block, a sliding groove, and a compression spring. The swing arm is hinged to the swing arm mounting base and the sliding block at both ends. The sliding block is held in place in the sliding groove by the compression spring, generating a certain elastic restraint force. When the heatsink is opened, the compression spring exerts an elastic force on the sliding block, causing it to abut against the docking port, keeping the swing arm upright. The interaction of the four swing arms maintains the heatsink at a certain height above the hard drive body. This design is simple and user-friendly. Users simply lift the heatsink slightly to a certain distance, and the compression spring automatically raises the swing arm. To close the heatsink, a slight downward pressure closes it to the hard drive body, completing the opening and closing action.

Detailed Implementation
[0033] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] Please see Figure 1-7 In this embodiment of the present invention, a high-efficiency heat-dissipating portable solid-state drive includes a hard drive body 10. The hard drive body 10 has a metal casing 11 and a main circuit board 12 disposed inside the metal casing 11. The main circuit board 12 is provided with a data transmission interface 13 extending out of the front side of the metal casing 11. It also includes a heat dissipation body 20 that can be covered on the upper part of the metal casing 11. The heat dissipation body 20 includes a fan bracket 21, a heat dissipation fan 22 disposed on the fan bracket 21, and a power supply wire 23 electrically connected between the heat dissipation fan 22 and the main circuit board 12. Swing arms are respectively provided at the four corners of the fan bracket 21. A fixed seat 24 is provided, and a swing arm support rod 25 is hinged to the fixed seat 24. At the four corners of the metal shell 11, there are docking ports 14 for docking with the fixed seat 24. Sliding grooves 15 are provided on both sides of the metal shell 11, and the two ends of the sliding grooves 15 are respectively docked with the docking ports 14. Sliding blocks 16 are slidably connected at the front and rear positions in the sliding grooves 15, and can slide to abut against the docking ports 14. The sliding blocks 16 are hinged to the swing arm support rod 25, and a compression spring 17 is provided between the sliding blocks 16 and the sliding grooves 15 to drive the sliding blocks 16 to abut against the docking ports 14.
[0035] In the above technical solution, by setting a heat dissipation body 20 on the hard disk body 10, the heat dissipation body 20 and the hard disk body 10 are cleverly connected by utilizing the four corner positions, and the connection method is to use a swing support rod 25 to connect them, so that the hard disk body 10 and the heat dissipation body 20 can cover each other when not in use, thereby achieving the purpose of easy portability.
[0036] When the hard drive body 10 is operating under high load, by raising and holding the heat sink 20 to maintain a certain distance between the heat sink 20 and the hard drive body 10, when the cooling fan 22 on the heat sink 20 is working, it can blow cold air towards the hard drive body 10 to dissipate heat from the surface of the hard drive body 10. Moreover, since the heat sink 20 is raised, the air circulation is greatly improved, so that the cooling fan 22 can work efficiently on the hard drive body 10, thereby achieving a more efficient heat dissipation effect.
[0037] In terms of structural design, the system employs a swing arm 25, a swing arm fixing seat 24, a sliding block 16, a sliding groove 15, and a compression spring 17. The swing arm 25 is hinged to the swing arm fixing seat 24 and the sliding block 16 at both ends. The sliding block 16 is elastically restrained within the sliding groove 15 by the compression spring 17. When the heat dissipation body 20 is opened, the compression spring 17 exerts an elastic force on the sliding block 16, causing it to abut against the docking port 14, keeping the swing arm 25 upright. The interaction of the four swing arms 25 maintains the heat dissipation body 20 at a height higher than the hard drive body 10. This structure is simple and easy for users to operate. If necessary, a control switch can be installed on the hard drive body 10 to flexibly control the operation of the cooling fan 22, allowing the cooling fan 22 to be turned on for heat dissipation when not needed.
[0038] Please see Figure 7In this embodiment of the invention, the main circuit board 12 integrates a main control chip 121, a flash memory chip 122, a cache chip 123, and a power management chip 124. The flash memory chip 122, cache chip 123, power management chip 124, data transmission interface 13, and power supply wire 23 are all electrically connected to the main control chip 121. The main control chip 121 manages the data read / write operations of the flash memory chip 122, rationally arranges the data transmission sequence, and ensures the efficiency and accuracy of data read / write. Simultaneously, the main control chip 121 also controls the operation of the cooling fan 22. If necessary, a temperature sensor can be installed inside the metal casing 11 to detect the internal temperature of the metal casing 11 in real time. When the internal temperature of the metal casing 11 reaches a preset high temperature value, the main control chip controls the cooling fan 22 to run and cool the metal casing 11. When the temperature of the metal casing 11 falls below a preset low temperature value, the main control chip 121 will turn off the cooling fan 22. If a control switch is provided, this operation can be manually performed via the control switch. The flash memory chip 122 is the actual carrier for data storage in the solid-state drive (SSD), and its performance and quality directly affect key indicators such as storage capacity and read / write speed. Some SSDs are equipped with a cache chip 123, whose main function is to improve data read / write speed and performance. The power management chip 124 is responsible for managing and regulating the power supply to the SSD, ensuring that all components operate normally under a stable voltage. The power supply cable 23 can be located at the rear of the hard drive body 10 and the heat sink body 20, passing through the fan bracket 21 and the metal casing 11 to connect the cooling fan 22 and the main circuit board 12. A receiving slot is provided at the rear of the metal casing 11, so that the power supply cable 23 is placed in the receiving slot after the casing is closed.
[0039] Please see Figure 4-5In this embodiment of the invention, the swing support rod 25 is further configured such that, when the swing arm fixing seat 24 is engaged with the docking socket 14, the end of the swing support rod 25 hinged to the swing arm fixing seat 24 is deeper in the docking socket 14 than the end of the swing support rod 25 hinged to the sliding block 16. This configuration allows the compression spring 17 to enhance the tightness of the cover between the heat dissipation body 20 and the hard disk body 10. Specifically, when the heat dissipation body 20 is closed on the hard disk body 10, the elastic force applied by the compression spring 17 to the swing support rod 25 will generate a downward component force on the end of the swing support rod 25 hinged to the swing arm fixing seat 24. Since the heat dissipation body 20 is closed on the hard disk body 10, the swing arm fixing seat 24 cannot move downwards, thus ensuring that the heat dissipation body 20 is firmly closed on the hard disk body 10. On the main body 10; during the opening of the heat dissipation body 20, a certain force is required to make the position of the end of the swing support rod 25 hinged to the swing arm fixing seat 24 within the docking socket 14 shallower than the position of the end of the swing support rod 25 hinged to the sliding block 16 within the docking socket 14. This allows the elastic force applied by the compression spring 17 to the swing support rod 25 to generate an upward component force on the end of the swing support rod 25 hinged to the swing arm fixing seat 24, enabling the compression spring 17 to drive the sliding block 16 and thus stand the swing support rod 25 upright. In addition, the swing support rod 25 is set to be in an inclined state when the sliding block 16 abuts against the docking socket 14, so that when the heat dissipation body 20 is pressed down, it can generate a component force on the sliding block 16 that overcomes the compression spring 17. Through this setting, combined with the state of the swing support rod 25 after the heat dissipation body 20 is closed, the user's operational convenience in closing and lifting the heat dissipation body 20 can be greatly improved.
[0040] Please see Figure 6 In this embodiment of the present invention, a concave-convex structure 26 is further provided between the inner wall of the swing arm fixing seat 24 and the docking port 14, so that the swing arm fixing seat 24 can be locked by the concave-convex structure 26 after docking with the docking port 14. With this setting, the hard disk body 10 and the heat dissipation body 20 after being covered can be more efficiently and firmly locked, thereby better ensuring the stability of the whole when carried.
[0041] Please see Figure 4-6In this embodiment of the utility model, it is further proposed that both sides of the sliding groove 15 are provided with blocking strips 151 that abut against the upper end of the sliding block 16, and the two blocking strips 151 are spaced apart, so that the swing support rod 25 can move between the two blocking strips 151. This structure is simple. In the production process, the metal shell 11 is mainly made of the lower shell 113 and the heat dissipation cover 111. The lower shell 113 is formed by aluminum extrusion molding and forms the structure of the sliding groove 15. The front and rear positions of the sliding groove 15 are CNC machined to form the structure of the mating socket 14. Finally, the heat dissipation cover 111 and the lower shell are respectively provided with front and rear covers to cover them. The front and rear covers and the heat dissipation cover 111 can be made of aluminum material. In particular, the heat dissipation cover 111 needs to ensure that it has a high thermal conductivity and heat dissipation effect. If necessary, heat dissipation fins 112 facing the cooling fan 22 can be provided on the heat dissipation cover 111 to enable the heat dissipation cover 111 to dissipate heat more efficiently. To ensure insulation, the front cover with the data transmission interface 13 can also be made of insulating material, and the heat dissipation cover 111 and the lower shell can be fixed by screws to the front cover and the rear cover.
[0042] Please see Figure 4-5 In this embodiment of the utility model, it is further proposed that both the sliding block 16 and the swing arm support are provided with hinge seats, and the sliding block 16 and the swing arm support are respectively hinged to both ends of the swing support rod 25 through the hinge seats; the sliding block 16 is also provided with a spring rod 161, the compression spring 17 is sleeved on the spring rod 161, and a blocking block 152 is provided in the middle of the sliding groove 15. The other end of the compression spring 17 is pressed and engaged with the blocking block 152, so that two sliding blocks 16 with opposite directions and complementary interference can be installed in one sliding groove 15 at the same time.
[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
