Description

Technical Field

[0001] This utility model relates to the field of hard disk copying devices, and specifically to a hard disk cloning machine. Background Technology

[0002] Traditional external hard drive docks typically require a computer connection to complete data copying between hard drives. This high dependence on a computer causes many inconveniences in practical use. For example, traditional devices cannot meet the needs of copying data between two hard drives when a computer is unavailable.

[0003] To address this issue, hard drive copying devices that support offline copying have emerged on the market. However, multi-bay offline copying devices generally generate a lot of heat due to the large data processing load, which not only affects data transfer efficiency but may also shorten the device's lifespan. Utility Model Content

[0004] To address at least one of the aforementioned problems, according to one aspect of the present invention, a hard disk cloning machine is provided.

[0005] This hard drive cloning machine includes a base; the base is equipped with a cloning mechanism and a heat dissipation mechanism; the cloning mechanism is configured to clone at least one hard drive; the heat dissipation mechanism is configured to simultaneously dissipate heat from the cloning mechanism and the hard drive mounted on it. This not only ensures the stability of the cloning mechanism's operation but also prevents hard drive failure due to overheating, thereby extending the lifespan of the hard drive cloning machine while maintaining data transfer efficiency.

[0006] In some embodiments, the heat dissipation mechanism includes a first vent, a second vent, and a fan; the cloning mechanism includes at least one hard disk interface for inserting a hard disk; the first vent and the second vent are disposed on a chassis, and the chassis is also provided with a first receiving cavity for accommodating the fan, the first vent and the second vent communicate the first receiving cavity with the outside, and the hard disk interface is disposed on the side of the first receiving cavity facing the second vent.

[0007] Therefore, by using a fan to blow cool air from the first vent through the first cavity and then out through the second vent, the hard drive connected to the hard drive interface facing the second vent in the first cavity can be cooled, which greatly improves the cooling efficiency compared with natural cooling.

[0008] In some embodiments, the first vent is located at the bottom of the base, and the bottom of the base is provided with legs to suspend the first vent. This allows cold air from the bottom of the base to enter the first receiving cavity through the first vent.

[0009] In some embodiments, the insertion direction of the hard drive interface is perpendicular to the communication direction between at least one of the first and second vents and the first receiving cavity. Therefore, when the cold air flowing into the first receiving cavity through the first vent exits the first receiving cavity through the second vent, the contact area with the hard drive inserted into the hard drive interface is maximized, thereby maximizing heat dissipation for the hard drive. Furthermore, when the first vent is located at the bottom of the chassis, the insertion direction of the hard drive interface can be parallel to the horizontal plane, so that the surface of the chassis where the second vent is located supports the hard drive inserted into the hard drive interface.

[0010] In some embodiments, the second vent is located on the side of the base opposite to the side where the first vent is located. This allows the cold air entering the first receiving cavity through the first vent to flow out quickly and smoothly through the second vent, thereby ensuring heat dissipation by maintaining the airflow rate.

[0011] In some implementations, multiple sets of second vents are provided, and the base between adjacent second vents forms connecting ribs that separate the hard drive from the fan. Thus, the hard drive connected to the hard drive interface is isolated from the fan by the connecting ribs, ensuring the stability of the hard drive cloning machine.

[0012] In some embodiments, at least two hard drive interfaces are provided; all hard drive interfaces are arranged side by side along a communication direction perpendicular to the second vent and the first receiving cavity, so that when the cold air flowing into the first receiving cavity through the first vent flows out of the first receiving cavity through the second vent, it can cool the hard drives connected to all hard drive interfaces; and / or adjacent hard drive interfaces are configured such that there is a gap between the hard drives connected thereto, so that when the cold air flowing into the first receiving cavity through the first vent flows out of the first receiving cavity through the second vent, it can flow out through the gap between the hard drives connected to adjacent hard drive interfaces, so as to ensure the smooth flow of cold air, ensure the flow rate of cold air, and thus ensure cooling efficiency.

[0013] In some embodiments, the hard drive cloning machine further includes a top cover, which is movably mounted on the base to cover the hard drive connected to the hard drive interface between itself and the base, or to connect the opening of the hard drive interface to the outside. The top cover is provided with a third vent that connects the second vent to the outside. Thus, not only can the stability of the hard drive connection to the hard drive interface be ensured by the top cover and the base when the hard drive connected to the hard drive interface is covered between itself and the base, but the third vent on the top cover also ensures that the cold air flowing into the first receiving cavity through the first vent, after flowing out of the first receiving cavity through the second vent, can flow out through the third vent, thus ensuring smooth cold air flow.

[0014] In some implementations, the chassis is provided with a clamping mechanism that presses the free end of the hard drive connected to the hard drive interface against the chassis. This clamping mechanism ensures the stability of the hard drive connection to the hard drive interface.

[0015] In some implementations, one end of the top cover is rotatably connected to the chassis, while the other end is detachably connected to the chassis to press the free end of the hard drive connected to the hard drive interface firmly against the chassis. This ensures the stability of the hard drive connection to the hard drive interface through the top cover.

[0016] In some embodiments, at least one of the first, second, and third vents is a honeycomb vent. This ensures the airflow velocity of the cold air passing through the vents.

[0017] In some implementations, the cloning mechanism also includes a control module connected to the hard drive interface, which is disposed within the first receiving cavity. This allows for cooling not only the control module but also the hard drive connected to the hard drive interface, ensuring data transmission efficiency while extending the lifespan of the hard drive cloning machine.

[0018] In some implementations, the fan is a silent fan. This avoids the fan affecting the stability of the hard drive interface and hard drive connection, ensuring the stability of data cloning.

[0019] In some embodiments, the side of the base near the control module is provided with at least one of the following: a fourth vent, a power interface, a USB interface, a working mode button, a switch, and an indicator light. At least one of these components is connected to the control module. Thus, the cold air entering the first receiving cavity from the first vent can also dissipate heat for the control module by flowing out through the fourth vent. Furthermore, the hard drive cloning machine can be connected to an external power source via the power interface to provide power. The hard drive cloning machine can connect to external data sources or connect to external devices such as computers via the USB interface to receive commands from external devices. The working mode control button receives user input for selecting the working mode (e.g., moving the button to the left indicates offline copying, while moving it to the right indicates connecting to an external device to copy external data to the hard drive). The switch receives power-on or power-off operations for the hard drive cloning machine. The indicator light displays the cloning status of the hard drive connected to the hard drive interface.

[0020] In some implementations, the connection between the control module and the hard drive interface is a PCIe connection. This enables high-speed read and write operations on the hard drive connected to the hard drive interface.

[0021] In some embodiments, the fan is configured to draw air from outside the first vent into the first receiving cavity to form cool air, and to exhaust air from the first receiving cavity through the second vent to cool the cloning mechanism and the hard drive connected to the hard drive interface.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0036] Figures 1 to 5 The diagram schematically illustrates a hard disk cloning machine according to a first embodiment of the present invention.

[0037] like Figure 4As shown, the hard disk cloning machine includes a base 20, a hard disk interface 211, and a fan 223; the base 20 is integrally formed or machined with a first receiving cavity 23, and a first ventilation port 221 and a second ventilation port 222 communicating the first receiving cavity 23 with the outside; the fan 223 is disposed in the first receiving cavity 23; the hard disk interface 211 is disposed on the side of the first receiving cavity 23 facing the second ventilation port 222, that is, the hard disk interface 211 is disposed on the side of the second ventilation port away from the first receiving cavity 23; the hard disk interface 211 is provided in at least one set and is used to insert a hard disk 100. When there is one set of hard disk interfaces 211, data can be cloned to the hard disk 100 inserted into that hard disk interface 211; when there are two sets of hard disk interfaces 211, data can be cloned to the hard disks 100 inserted into the two sets of hard disk interfaces 211 respectively, or data from one of the hard disks 100 inserted into the two sets of hard disk interfaces 211 can be cloned to the other hard disk 100; when there are four sets of hard disk interfaces 211, data can be cloned to the hard disks 100 inserted into the four sets of hard disk interfaces 211 respectively, or data from one of the hard disks 100 inserted into the four sets of hard disk interfaces 211 can be cloned to the other three hard disks 100; and so on. When there are N sets of hard disk interfaces 211, data can be cloned to the hard disks 100 inserted into the N sets of hard disk interfaces 211 respectively, or data from one of the hard disks 100 inserted into the N sets of hard disk interfaces 211 can be cloned to the other N-1 hard disks 100.

[0038] In some embodiments, the fan 223 is configured to draw air from outside the first vent 221 into the first receiving cavity 23 to generate cool air, and to exhaust air from the first receiving cavity 23 through the second vent 222 to dissipate heat from the hard drive 100 connected to the hard drive interface 211. In some embodiments, such as Figure 4 As shown, to facilitate the installation of the fan 223, the mounting base 20 includes a detachably connected upper housing 201 and a base 202, which together form a first receiving cavity 23 when connected. In some preferred embodiments, the fan 223 is a silent fan 223 to avoid affecting the stability of the connection between the hard disk interface 211 and the hard disk 100, thus ensuring the stability of data cloning.

[0039] When using this hard drive cloning machine, the fan 223 blows the cold air from the first vent 221 through the first receiving cavity 23 and then out through the second vent 222 to cool the hard drive interface 211 located in the first receiving cavity 23 facing the second vent 222 and the hard drive 100 connected thereto. Compared with natural cooling, this greatly improves the cooling efficiency, ensures the stability of the cloning work, and extends the service life of the hard drive cloning machine.

[0040] In some embodiments, such as Figures 1 to 5 As shown, the first vent 221, the second vent 222, and the fan 223 constitute the heat dissipation mechanism 22 of one embodiment of this application.

[0041] In some embodiments, such as Figure 2 and Figure 4 As shown, the first ventilation opening 221 is integrally formed or machined on the bottom of the base 20. The bottom of the base 20 is integrally formed, machined, or connected to a support leg 24 to elevate the first ventilation opening 221, allowing cold air from the bottom of the base 20 to enter the first receiving cavity 23 through the first ventilation opening 221. When the base 20 includes an upper housing 201 and a base 202, the support leg 24 is integrally formed, machined, or connected to the base 202. In some preferred embodiments, such as... Figure 4 As shown, in order to ensure that the hard drive cloning machine can be placed stably, a foot pad 241 is provided at the bottom of the support 24. The pad can be made of a cushioning material such as silicone to make the bottom of the support 24 have an anti-slip function.

[0042] In some embodiments, such as Figure 4 As shown, the second vent 222 is located on the side of the base 20 opposite to the side where the first vent 221 is located. Preferably, the first vent 221 and the second vent 222 are located on opposite sides of the fan 223 so that the cold air entering the first receiving cavity 23 through the first vent 221 can flow out quickly and smoothly through the second vent 222, thereby ensuring the heat dissipation effect by ensuring the flow rate of the cold air.

[0043] In some embodiments, such as Figure 1 As shown, multiple sets of second ventilation openings 222 are provided. The base 20 between adjacent second ventilation openings 222 forms a connecting rib 25 that separates the hard disk 100 from the fan 223. The connecting rib 25 separates the hard disk 100 connected to the hard disk interface 211 from the fan 223 to ensure the stability of the hard disk cloning machine.

[0044] In some embodiments, at least one of the first vent 221 and the second vent 222 is a honeycomb vent to ensure the airflow speed of cold air through the vent. Compared with only the fan 223, the airflow is increased by 30%. Compared with the passive cooling solution (fanless solution 223), the temperature of the hard drive 100 is reduced by 12°C to 18°C ​​during multi-disk cloning, avoiding speed reduction or interruption due to high temperature.

[0045] In some embodiments, continue to refer to Figure 4As shown, the hard disk cloning machine also includes a control module 212 connected to the hard disk interface 211. When there is more than one set of hard disk interfaces 211, the control module 212 can enable data transfer between hard disks 100 connected to different hard disk interfaces 211, thereby realizing the offline cloning function.

[0046] In some embodiments, the interconnected hard disk interface 211 and control module 212 constitute a cloning mechanism 21 of an embodiment of this application.

[0047] In some embodiments, such as Figure 1 , Figures 3 to 5 As shown, the insertion direction of the hard disk interface 211 is perpendicular to the communication direction between at least one of the first vent 221 and the second vent 222 and the first receiving cavity 23. This maximizes the contact area between the cold air flowing into the first receiving cavity 23 through the first vent 221 and the hard disk 100 inserted into the hard disk interface 211 when it flows out of the first receiving cavity 23 through the second vent 222, thereby maximizing the heat dissipation of the hard disk 100. Furthermore, when the first vent 221 is located at the bottom of the chassis 20, the insertion direction of the hard disk interface 211 can also be parallel to the horizontal plane, so that the surface of the chassis 20 where the second vent 222 is located can support the hard disk 100 inserted into the hard disk interface 211.

[0048] In some embodiments, at least two hard disk interfaces 211 are provided; all hard disk interfaces 211 are arranged side by side along a communication direction perpendicular to the second vent 222 and the first receiving cavity 23, so that when the cold air flowing into the first receiving cavity 23 through the first vent 221 flows out of the first receiving cavity 23 through the second vent 222, it can cool the hard disks 100 connected to all hard disk interfaces 211; and / or adjacent hard disk interfaces 211 are configured such that there is a gap 101 between the hard disks 100 connected thereto, so that when the cold air flowing into the first receiving cavity 23 through the first vent 221 flows out of the first receiving cavity 23 through the second vent 222, it can flow out through the gap 101 between the hard disks 100 connected to adjacent hard disk interfaces 211, so as to ensure the smooth flow of cold air, ensure the flow rate of cold air, and thus ensure cooling efficiency. Preferably, when the second vent 222 is located on the side of the base 20 opposite to the side where the first vent 221 is located, and the adjacent hard disk interfaces 211 are configured such that there is a gap 101 between the hard disks 100 connected thereto, so that when the cold air flowing into the first receiving cavity 23 through the first vent 221 flows out of the first receiving cavity 23 through the second vent 222, it can flow out through the gap 101 between the hard disks 100 connected to the adjacent hard disk interfaces 211, thus forming a directional airflow on the hard disk cloning machine to precisely cool the concentrated heat source when cloning multiple disks simultaneously.

[0049] In some embodiments, such as Figure 4 As shown, the control module 212 is disposed in the first receiving cavity 23 so that the heat dissipation mechanism 22 dissipates heat from the control module 212 and the hard disk interface 211 and the hard disk 100 connected thereto. This enables the heat dissipation mechanism 22 to simultaneously dissipate heat from the cloning mechanism 21 and the hard disk 100 installed on the cloning mechanism 21, ensuring data transmission efficiency and extending the service life of the hard disk cloning machine.

[0050] In some embodiments, such as Figures 1 to 5 As shown, the base 20 has at least one of the following on one side of the proximity control module 212: a fourth ventilation port 271, a power interface 272, a USB interface 273, a working mode button 274, a switch, and an indicator light 275. At least one of these components is connected to the control module 212, allowing the cold air entering the first receiving cavity 23 from the first ventilation port 221 to also dissipate heat from the control module 212 by flowing out through the fourth ventilation port 271. Furthermore, the hard drive cloning machine can be connected to an external power source via the power interface 272 to provide power. It can also connect to external data or external devices such as computers via the USB interface 273 to receive commands from external devices. The working mode control button receives user input for selecting the working mode, and the switch receives power-on or power-off operations. The indicator light 275 displays the cloning status of the hard drive 100 connected to the hard drive interface 211. The fourth ventilation port 271, power interface 272, USB interface 273, working mode button 274, switch and indicator light 275 can be set on different sides of the base 20 as needed, as long as they are close to the control module 212.

[0051] In some embodiments, the connection between the control module 212 and the hard disk interface 211 is a PCIe connection to enable high-speed read and write of the hard disk 100 connected to the hard disk interface 211. Relying on the high bandwidth (theoretically 128GB / s) and low latency characteristics of PCIe 4.0, efficiency is improved through multi-channel parallel transmission. When four sets of hard disk interfaces 211 are set, the x4 channel of PCIe 4.0 can provide approximately 8GB / s bandwidth, with a maximum single disk read and write speed of 7400MB / s, and cloning 1TB of data can be completed in as little as 8 minutes.

[0052] Figures 6 to 8 A hard disk cloning machine according to the second embodiment of this application is shown as an example.

[0053] like Figure 6 and Figure 8As shown, the difference between this embodiment of the hard disk cloning machine and the previous embodiment is that, based on the previous embodiment, it further includes a top cover 30. The top cover 30 is movably mounted on the base 20 to cover the hard disk 100 connected to the hard disk interface 211 between itself and the base 20, or to connect the opening of the hard disk interface 211 to the outside. The top cover 30 is provided with a third ventilation port 31 that can connect the second ventilation port 222 to the outside. This ensures that, not only when the top cover 30 covers the hard disk 100 connected to the hard disk interface 211 between itself and the base 20, the stability of the hard disk 100 connected to the hard disk interface 211 is guaranteed by the top cover 30 and the base 20; the third ventilation port 31 on the top cover 30 also ensures that the cold air flowing into the first receiving cavity 23 through the first ventilation port 221, after flowing out of the first receiving cavity 23 through the second ventilation port 222, can flow out through the third ventilation port 31, thus ensuring smooth flow of cold air. In some preferred embodiments, such as... Figure 6 and Figure 8 As shown, the third vent 31 is a honeycomb vent to ensure the airflow speed of cold air passing through the vent.

[0054] In some embodiments, such as Figure 8 As shown, the base 20 is provided with a pressure plate 261 that can rotate about a direction perpendicular to the hard disk 100 insertion interface 211. That is, the pressure plate 261 rotates about a first rotating shaft relative to the base 20. The pressure plate 261 is located on one side of the first rotating shaft. The rotation of the pressure plate 261 can press the free end of the hard disk 100 connected to the hard disk interface 211 onto the base 20, or release the free end of the hard disk 100 connected to the hard disk interface 211 that is pressed onto the base 20, so as to ensure the stability of the hard disk 100 connected to the hard disk interface 211.

[0055] In some embodiments, such as Figure 8 As shown, a pressure plate 261, which is rotatably connected to the base 20 in a direction perpendicular to the hard disk 100 insertion interface 211, constitutes a clamping mechanism 26 in one embodiment of this application.

[0056] In some embodiments, such as Figures 6 to 8 As shown, one end of the top cover 30 is rotatably connected to the base 20, and the other end is detachably connected to the base 20, so as to press the free end of the hard disk 100 connected to the hard disk interface 211 onto the base 20, so as to ensure the stability of the hard disk 100 connected to the hard disk interface 211 through the top cover 30.

[0057] In one embodiment where the upper cover 30 and the base 20 are detachably connected, the upper cover 30 and the base 20 are provided with magnets 32 that can be magnetically connected to each other when the upper cover 30 is closed on the base 20; or one of the upper cover 30 and the base 20 is provided with a magnet 32 ​​and the other is a ferromagnetic material, so that when the upper cover 30 is closed on the base 20, the magnet 32 ​​can be magnetically connected to the ferromagnetic material.

[0058] As another embodiment of the cloning mechanism 21, the cloning mechanism 21 includes only the hard disk interface 211 and does not include the control module 212.

[0059] As another embodiment of the heat dissipation mechanism 22, the heat dissipation mechanism 22 includes only the first vent 221 and the second vent 222, and does not include the fan 223.

[0060] Regardless of which of the above implementation methods is adopted, the module of the hard disk cloning machine of this application can be referenced. Figure 9 The implementation is as shown, namely, electrically connected to the main chip of the control module 212 via a data interface (e.g., USB interface 273); the main chip is connected to multiple hard disk interfaces 211 (e.g., M.2 hard disk interfaces) via multiple PCIe controllers; and it also uses CRC (Cyclic Redundancy Check) verification with the PCIe controllers to achieve independent speed measurement, full disk comparison, and clone verification error correction functions. In some embodiments, the main chip can be an ASM2464PDX chip.

[0061] The hard disk cloning machine described in this application can be used in scenarios requiring high data consistency, such as data center backup and multi-camera synchronous storage for film and television production.

[0062] In this invention, the connection or installation is a fixed connection unless otherwise specified. A fixed connection can be implemented as a detachable or non-detachable connection commonly used in the prior art. A detachable connection can be implemented using existing technologies, such as threaded connections or keyed connections. A non-detachable connection can also be implemented using existing technologies, such as welding or adhesive bonding.

[0063] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
