[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] This utility model embodiment provides a network storage device, such as... Figures 1 to 5 As shown, the network storage device includes a housing 1, a hard disk rack 2, a hard disk 3, a fan 4, a main control circuit board 5, and a connecting circuit board 6; the housing 1 includes a main shell 11 and a bottom shell 12, the bottom shell 12 being installed at the bottom of the main shell 11; a partition 111 is provided inside the main shell 11, the partition 111 dividing the interior of the main shell 11 into a bottom mounting cavity 112 and an upper cavity 113.

[0029] The hard drive inner frame 2 is installed in the upper cavity 113, and the hard drive 3 is detachably inserted into the hard drive inner frame 2; the connecting circuit board 6 is installed at the bottom of the hard drive inner frame 2 and is electrically connected to the hard drive 3; the main control circuit board 5 is installed in the bottom mounting cavity 112 and is electrically connected to the connecting circuit board 6; the partition 111 has a mounting port 1111, the fan 4 is installed in the mounting port 1111 and is electrically connected to the main control circuit board 5.

[0030] The bottom shell 12 is provided with a first air vent 121, and the main shell 11 is provided with a second air vent 114 on the side corresponding to the bottom mounting cavity 112; the first air vent 121 is located below the main control circuit board 5, and the second air vent 114 is located above the main control circuit board 5.

[0031] The network storage device of this utility model divides the interior of the main shell 11 into a bottom mounting cavity 112 and an upper cavity 113 by setting a partition 111. The hard disk inner frame 2 is installed in the upper cavity 113, the connecting circuit board 6 is installed at the bottom of the hard disk inner frame 2, the main control circuit board 5 is installed in the bottom mounting cavity 112, and the fan 4 is installed in the mounting port 1111. Further, a first air vent 121 is provided on the bottom shell 12, and a second air vent 114 is provided on the side of the main shell 11 corresponding to the bottom mounting cavity 112. The first air vent 121 is located below the main control circuit board 5, and the second air vent 114 is located above the main control circuit board 5. In this way, when fan 4 is working, outside air enters the bottom mounting cavity 112 from the first air vent 121 and the second air vent 114 respectively. That is, the air enters the bottom mounting cavity 112 from below and above the main control circuit board 5, first comprehensively and quickly removing the heat generated by the main control circuit board 5 from both below and above. The second air vent 114 is located above the main control circuit board 5, ensuring that the airflow is not blocked by the main control circuit board 5, guaranteeing the airflow volume and speed. Then, the air passes through the partition 111 and blows towards the connecting circuit board 6 and the hard drive 3, ultimately removing the heat from the connecting circuit board 6 and the hard drive 3, further improving the heat dissipation effect of the network storage device. Of course, in another embodiment, the first air vent 121 and the second air vent 114 can also serve as air outlets, allowing the internal air of the network storage device to flow out through the first air vent 121 and the second air vent 114.

[0032] The internal hard drive rack 2 provides mounting support for the hard drive 3 and features a removable design, allowing users to easily replace or upgrade the hard drive 3 according to their storage needs, enhancing the flexibility and scalability of the device. The hard drive 3, as the core component for data storage, is responsible for storing various user data information. Its removable installation within the internal hard drive rack 2 facilitates management and maintenance. The fan 4 is installed in the mounting port 1111 on the partition 111 and is electrically connected to the main control circuit board 5, providing heat dissipation for the network storage device. This ensures that the main control circuit board 5 and other components operate stably in a suitable temperature environment, extending the device's lifespan. The main control circuit board 5, installed in the bottom mounting cavity 112, is the core control unit of the network storage device, responsible for handling critical tasks such as data storage and transmission. It is electrically connected to the connecting circuit board 6, enabling smooth data transmission and storage management between the hard drive 3 and the main control circuit board 5. The connecting circuit board 6, installed at the bottom of the internal hard drive rack 2 and electrically connected to the hard drive 3, is responsible for transmitting data transmission signals from the hard drive 3 to the main control circuit board 5, ensuring the stability and reliability of data transmission. It serves as a bridge for communication between the hard drive 3 and the main control circuit board 5.

[0033] Furthermore, multiple vents 21 are provided at the bottom of the hard drive inner frame 2, corresponding to the fan 4. The hard drive 3 generates heat during operation, especially when multiple hard drives 3 are working simultaneously, resulting in significant heat accumulation. By providing vents 21 at the bottom of the hard drive inner frame 2, corresponding to the fan 4, the airflow from the fan 4 can directly blow onto the hard drive 3, carrying away the heat generated by the hard drive 3. This effectively reduces the temperature of the hard drive 3, making the cooling airflow more concentrated and efficient, preventing heat from accumulating inside the hard drive inner frame 2, and ensuring that the hard drive 3 operates stably at a suitable temperature.

[0034] Specifically, the network storage device further includes a top cover 7, which is detachably mounted on the end of the main housing 11 away from the bottom housing 12. The top cover 7 has a third vent 71, allowing it to be removed from the main housing 11 for disassembly. The top cover 7 provides additional protection to the top of the network storage device, effectively preventing dust, liquids, and other foreign objects from entering the device from the top. Magnets can be installed on the ends of the top cover 7 and the main housing 11 away from the bottom housing 12 for magnetic closure. The third vent 71 provides an exhaust channel for hot air inside the network storage device, allowing it to be smoothly discharged from the device to the external environment. This effectively reduces the internal temperature of the network storage device, preventing damage to electronic components due to overheating, thereby improving the stability and reliability of the device. Alternatively, in another embodiment, the third vent 71 can also serve as an air inlet, allowing external air to enter the network storage device through it.

[0035] The hard drive inner frame 2 is mounted on the partition 111 via the first mounting structure 8; the fan 4 is mounted on the bottom of the hard drive inner frame 2 via the second mounting structure 9 and is located in the mounting port 1111; the main control circuit board 5 is mounted in the bottom mounting cavity 112 via the third mounting structure 10. This solution achieves the installation of the hard drive inner frame 2, the fan 4, and the main control circuit board 5 through the first mounting structure 8, the second mounting structure 9, and the third mounting structure 10.

[0036] Specifically, the first mounting structure 8 consists of first studs 81 respectively disposed on the bottom of the hard disk inner frame 2 and on the partition 111. The hard disk inner frame 2 is mounted on the partition 111 by the first studs 81 and screws. The first studs 81 on the bottom of the hard disk inner frame 2 and on the partition 111 correspond to each other. When the screw passes through the stud on the bottom of the hard disk inner frame 2 and is screwed into the stud on the partition 111, the hard disk inner frame 2 can be firmly fixed on the partition 111, ensuring that the hard disk inner frame 2 will not shift or fall off during operation. Even under the vibration generated by the operation of the hard disk 3 and external impacts, it can remain stable, thereby providing stable support for the hard disk 3 and ensuring the normal operation of the hard disk 3 and the safe storage of data. Specifically, first studs 81 are provided at the four corners of the bottom of the hard disk inner frame 2, and corresponding studs are provided on the partition 111 to cooperate with the first studs 81.

[0037] The second mounting structure 9 consists of a second stud 91 located at the bottom of the hard drive inner frame 2 and a first screw hole located on the fan 4. The fan 4 is mounted on the bottom of the hard drive inner frame 2 via the second stud 91 and the first screw. The second stud 91 is located at the bottom of the hard drive inner frame 2, and the first screw hole is located on the fan 4. When the fan 4 is installed via the first stud 91, the first screw hole, and the screw, the cooperation between the stud and the screw hole provides precise positioning, ensuring that the fan 4 is installed in the correct position at the bottom of the hard drive inner frame 2.

[0038] The third mounting structure 10 consists of a third stud 101 disposed in the bottom mounting cavity 112 and a second screw hole 102 disposed on the main control circuit board 5. The main control circuit board 5 is mounted in the bottom mounting cavity 112 via the third stud 101, the second screw hole 102, and a second screw. The third stud 101 is disposed in the bottom mounting cavity 112, and the second screw hole 102 is disposed on the main control circuit board 5. Through the cooperation of the third stud 101, the second screw hole 102, and the screw, the main control circuit board 5 can be precisely positioned and securely mounted in the bottom mounting cavity 112. This design ensures the correct position of the main control circuit board 5 inside the network storage device, maintaining a suitable distance and connection relationship with other components such as the connecting circuit board 6 and the hard disk 3, which is beneficial for data transmission and heat dissipation. Simultaneously, the stable mounting method prevents the main control circuit board 5 from shifting or falling off due to vibration or external impact during operation, ensuring its stable operation and reducing problems such as poor contact or damage caused by circuit board displacement, thereby improving the reliability and stability of the entire network storage device.

[0039] Furthermore, the second stud 91 has an axially extending limiting rib 911 on its peripheral wall, and a buffer ring 20 is fitted onto the second stud 91, the buffer ring 20 abutting between the limiting rib 911 and the first screw hole. The limiting rib 911 can axially position the buffer ring 20, ensuring the correct position of the buffer ring 20 on the second stud 91. When the buffer ring 20 is fitted onto the second stud 91, the limiting rib 911 can prevent the buffer ring 20 from moving axially, keeping it within a set position range. The buffer ring 20 can absorb the vibration generated by the fan 4 during operation, reducing the impact of vibration on the hard drive inner frame 2 and the hard drive 3, thereby improving the stability and reliability of the hard drive 3. The buffer ring 20 is usually made of a material with a certain degree of elasticity, such as rubber or elastic rings. Furthermore, when the buffer ring 20 abuts between the limiting rib 911 and the first screw hole, it generates a certain preload. This preload can enhance the connection stability between the fan 4 and the hard drive inner frame 2, ensuring that the fan 4 will not loosen or shift during operation. Specifically, the bottom of the hard drive inner frame 2 is provided with second studs 91 corresponding to the four corners of the fan 4, and the four corners of the fan 4 are provided with first screw holes.

[0040] The bottom shell 12 is provided with a first support leg 122 for supporting the network storage device. The first support leg 122 has a support cavity 1221. The second screw passes through the support cavity 1221 into the bottom mounting cavity 112 and is screwed onto the third stud 101 through the second screw hole 102. The first support leg 122 serves as a support structure for the network storage device, enabling the device to be placed stably on a desktop or other supporting surface. The support cavity 1221 provides space for the second screw to pass through, allowing the screw to enter the bottom mounting cavity 112 from the outside. This design makes the installation and removal of the main control circuit board 5 more convenient and also hides the second screw. Specifically, the third stud 101 is located on the side of the partition 111 facing the bottom mounting cavity 112.

[0041] A dustproof mesh is attached to the inner side of the second air vent 114, while no dustproof mesh is installed at the first air vent 121. The dustproof mesh attached to the inner side of the second air vent 114 effectively filters dust and impurities from the air entering the network storage device. When air enters through the second air vent 114, dust is intercepted by the dustproof mesh, preventing it from entering the device and thus reducing dust contamination and damage to components such as the main control circuit board 5, connecting circuit board 6, and hard drive 3, extending the service life of these components. The first air vent 121, located below the main control circuit board 5, is one of the key channels for heat dissipation. The absence of a dustproof mesh reduces airflow resistance, allowing air to enter the bottom mounting cavity 112 more smoothly, quickly carrying away the heat generated by the main control circuit board 5 and improving the heat dissipation efficiency of the network storage device.

[0042] The bottom shell 12 is provided with a mounting base 123 extending toward the bottom mounting cavity 112, and the first support leg 122 is installed in the mounting base 123.
