[0025] Please refer to Figure 1 , Figure 1 The utility model discloses a multifunctional mobile hard disk module schematic diagram, and the utility model discloses a multifunctional mobile hard disk includes hard disk body 1 and hard disk box 2. The hard disk box 2 is multifunctional hard disk box of the utility model. The hard disk box 2 includes casing 21, internal circuit 22, a plurality of interfaces 23, magnetic attraction module 24 and cooling fan 25. Internal circuit 22, cooling fan 23 and magnetic attraction module 24 all are arranged in the inside of casing 21. The casing 21 is equipped with hard disk installation cavity 211, and the hard disk installation cavity 211 is equipped with the contact point connected with internal circuit 22. The hard disk body 1 is installed in the hard disk installation cavity 211, is connected with internal circuit 22 through the contact point in the hard disk installation cavity 211. Internal circuit 22 is connected with a plurality of interfaces 23, and a plurality of interfaces 23 are used for connecting the host computer of outside, and therefore the hard disk body 1 can be connected with the host computer of outside through internal circuit 22 and a plurality of interfaces 23, to carry out data transmission with the host computer of outside. Magnetic attraction module 24 is installed at the back of hard disk box 2 and is used for adsorbing the shell of the host computer of outside, so that the mobile hard disk can be adsorbed and fixed on the shell of the host computer of outside. The air outlet of cooling fan 25 is arranged at the back of hard disk box and is used for assisting the heat dissipation of hard disk body 1 and / or the host computer of outside.
[0026] Please refer to Figures 2-3 , Figure 2 It is the structure schematic diagram of the front of multifunctional hard disk box of the utility model, Figure 3 It is the structure schematic diagram of the back of multifunctional hard disk box of the utility model.
[0027] Specifically, the casing 21 is a cuboid. For the convenience of description, the cuboid casing 21 can be remembered as follows, Figure 2 The side facing the observer is the front, Figure 2 The side facing away from the observer is the back, Figure 2 The side on the left is the left side, Figure 2The right side of the right side surface, Figure 2 The upward-facing surface is a top surface, Figure 2 The downward-facing surface is a bottom surface. In this embodiment, the hard disk mounting cavity 211 of the shell 21 is located at the upper left of the front surface of the hard disk case 2.
[0028] Specifically, the plurality of interfaces 23 include a first interface 231 and other interfaces. The first interface 231 is a male head, which is arranged outside the shell 21 and connected to the internal circuit 22 through a data line L. The other interfaces are female seats, which are arranged inside the shell 21 and directly connected to the internal circuit 22. The shell 21 is also provided with a first interface receiving groove 212, which is matched in shape and position with the first interface male head 231. The first interface male head 231 can be received by being inserted into the first interface receiving groove 212.
[0029] The conventional hard disk case usually only provides an interface, and if the user needs to use a data line, the user needs to additionally purchase and install the data line, which is inconvenient to use. The hard disk case of the present application is provided with a fixed data line L for the first interface 231 with a high frequency of use, so that the user no longer needs to additionally purchase and install the data line, which is more convenient to use. Since the data line L and the first interface male head 231 are exposed outside the shell 21, in order to facilitate storage and aesthetics, the present application also provides the first interface male head 231 with a first interface receiving groove 212. The type of the first interface 231 and the other interfaces can be determined by the actual needs of those skilled in the art. Considering that the USB-C interface has a high frequency of use at present, in this embodiment, the first interface 231 is a USB-C interface, and the other interfaces include an HDMI interface 232, a USB 3.0 interface 233, and a USB 2.0 interface 234.
[0030] Further, since the data line L of the first interface male head 231 is exposed outside the shell 21, if the position of the data line L is not limited, the data line L can be easily tangled, which makes storage inconvenient. In order to store the data line L of the first interface male head 231 so that the data line L can be closely attached to the hard disk case 2 in the storage state, the bottom surface of the shell 21 is in a stepped shape, i.e., the bottom surface of the shell 21 is divided into a convex side and a concave side, the convex height of the convex side is higher than the convex height of the concave side, and the first interface receiving groove 212 is arranged at the top of the first side surface of the shell 21 close to the concave side. In this embodiment, the convex side refers to the left side of the bottom surface shown in Figure 2 The concave side refers to the right side of the bottom surface shown in Figure 2 The first side surface refers to the right side surface close to the concave side (i.e., the right side). Figure 2
[0031] The data cable L is divided into the following sections from root to tip: a root bend L1, a bottom straight section L2, a corner bend L3, and a side straight section L4. The root of the data cable L is fixed to the concave side of the bottom surface of the housing (i.e., Figure 2 Located at the innermost position on the right side, its extension direction is perpendicular to the bottom surface of the housing, and it is connected to the straight portion L2 on the bottom surface through the root bend L1. The straight portion L2 on the bottom surface is in close contact with the concave side of the bottom surface of the housing (i.e., Figure 2 On the right side), it is connected to the side straight portion L4 via the corner bend L3, and the bottom straight portion L2 and the side straight portion L4 together form a bent "L" shape. The side straight portion L4 is in close contact with the first side of the housing (i.e., Figure 2 Right side), from the first side of the housing (i.e. Figure 2 The bottom of the right side extends to the first side (i.e. Figure 2 The top of the right side (i.e., the top of the right side). The first male connector 231 (i.e., the USB male connector) is located inside the end of the straight section L4 on the side of the data cable L, so that the first male connector 231 (i.e., the USB male connector) can be stored in the first side (i.e., the top of the right side). Figure 2 The first male connector is located in the top of the right side (the first interface male connector storage slot 212).
[0032] Furthermore, the first side of the housing (i.e. Figure 2 The right side has corresponding connection ports for other interfaces (i.e., HDMI interface 232, USB 3.0 interface 233, and USB 2.0 interface 234) in its center. When the first male connector 231 (i.e., the USB male connector) is stored in the first male connector storage slot 212, the straight side portion L4 of the data cable covers the corresponding connection ports of the other interfaces, providing protection and dust prevention for the other interfaces. The HDMI male connector, USB 3.0 male connector, and / or USB 2.0 male connector of the external host can be inserted into the corresponding connection ports of the HDMI interface 232, USB 3.0 interface 233, and / or USB 2.0 interface 234 to connect the HDMI interface 232, USB 3.0 interface 233, and / or USB 2.0 interface 234, thereby enabling data transmission with the hard disk body 1 through the internal circuit 22.
[0033] The reason why the bottom surface of the housing 21 is stepped is to accommodate the root bend L1 and the straight bottom part L2 of the data cable L, so that the concave side of the bottom surface of the housing 21 (i.e. Figure 2 The height of the protrusion on the right side, plus the height of the root bend L1 and the straight bottom part L2 of the data cable L, can be aligned with the convex side of the bottom surface of the housing 21 (i.e., the right side). Figure 2the convex side of the bottom surface of the shell 21 (i.e. Figure 2 the convex side of the bottom surface of the shell 21 (i.e. Figure 2 the convex side of the bottom surface of the shell 21 (i.e.
[0034] Further, since the root bending portion L1 and the bottom linear portion L2 of the data line L do not need to be moved in actual use, in order to facilitate storage, the position of the root bending portion L1 and the bottom linear portion L2 of the data line L is also limited. The bottom end of the front surface and the back surface of the shell 21 extends to be flush with the convex side of the bottom surface of the shell (i.e. Figure 2 The shell is also provided with a cover plate 213; the cover plate 213 is perpendicular to the front surface and the back surface of the shell 21, parallel to the bottom surface of the shell 21, and covers the outside of the root bending portion L1 and the bottom linear portion L2 of the data line L. It can be seen that the front surface and the back surface of the shell 21 and the cover plate 213 together enclose the root bending portion L1 and the bottom linear portion L2 of the data line L, thereby limiting the position of the root bending portion L1 and the bottom linear portion L2 of the data line, so that the bottom linear portion L2 of the data line L remains close to the bottom surface of the shell, facilitating storage and arrangement.
[0035] Specifically, please refer to Figure 3 , the magnetic attraction module 24 is arranged on the back surface of the hard disk box 2, which is used to attract the shell of an external host, so that the user can magnetically fix the mobile hard disk on the surface of the external host when using the mobile hard disk. In this embodiment, the magnetic attraction module is specifically a MagSafe magnetic attraction module, which is arranged on the upper middle part of the back surface of the hard disk box 2.
[0036] Specifically, please refer to Figures 2-3 , the heat dissipation fan 25 is a turbine fan, and the air outlet direction thereof faces the back surface of the hard disk box 2. The back surface of the shell 21 is provided with an air outlet 214 opposite to the air outlet position of the heat dissipation fan. In this embodiment, the heat dissipation fan 25 is arranged on the lower left part of the front surface of the hard disk box.
[0037] Further, the heat dissipation fan 25 has two working modes, including automatic mode and performance mode.
[0038] Further, the internal circuit 22 of the hard disk box is provided with a thermistor for detecting the working temperature of the mainboard storage particle area in the hard disk body 1; the main control chip of the internal circuit 22 of the hard disk box obtains the working temperature through the thermistor. When the heat dissipation fan is in automatic mode, the main control chip of the internal circuit 22 of the hard disk box adaptively controls the power supply voltage of the heat dissipation fan 25 according to the working temperature; when the heat dissipation fan 25 is in performance mode, the main control chip of the internal circuit 22 of the hard disk box forces the heat dissipation fan to work at the maximum power supply voltage.
[0039] Further, when the heat dissipation fan is in automatic mode, the main control chip of the internal circuit 22 of the hard disk box adaptively controls the power supply voltage of the heat dissipation fan 25 according to the working temperature, specifically including: when the working temperature is < 35℃, the heat dissipation fan 25 is controlled to stop working; when the working temperature is in the interval [35℃, 50℃], the heat dissipation fan 25 is controlled to work at a power supply voltage of 3.3V, and until the working temperature drops to < 30℃, the heat dissipation fan is controlled to stop working; when the working temperature is > 50℃, the heat dissipation fan 25 is controlled to work at the maximum power supply voltage of 5V.
[0040] Further, the front surface of the hard disk box shell 21 is also provided with a PSSD function opening switch 217 connected with the internal circuit 22. The PSSD function opening switch 217 is a toggle switch, which is used to control the mobile hard disk to open or close the PSSD function.
[0041] The use method and technical effects of the utility model are as follows:
[0042] 1. When storing, the user inserts the first male connector 231 into the first interface storage slot 212 of the housing 21. At this time, the straight part L4 of the data line L of the first male connector 231 is close to the first side of the housing 21 and covers the other interfaces. On the one hand, it fixes the position of the data line L and the first male connector 231, making it easy to store. On the other hand, the data line L covering the other interfaces also plays a role in protecting and preventing dust from the other interfaces.
[0043] 2. In use, the user places the hard disk body 1 into the hard disk mounting cavity 211 to assemble the portable hard disk; pulls the first interface male connector 231 out of the first interface storage slot 212 to expose other interfaces; inserts other interface male connectors of the external host into the other interfaces, or inserts the first interface male connector 231 into the first interface female connector of the external host, so that the portable hard disk can establish a connection with the external host and perform data transmission.
[0044] 3. When using the external hard drive, the user can also bring the back of the hard drive enclosure close to the metal casing of the host. At this time, the magnetic module 24 of the hard drive enclosure will be attracted to the casing of the external host, so that the external hard drive is fixed on the surface of the external host. This can reduce the amount of desktop space occupied and keep the work area tidy, and also prevent the connection from being interrupted due to the movement of the external hard drive.
[0045] 4. When the cooling fan 25 of the hard drive enclosure is working, it can accelerate the heat dissipation of the portable hard drive and prevent overheating of the motherboard storage chip area of the hard drive body 1. When the portable hard drive is magnetically attached to the external casing of the host, the cooling fan 25 can also assist in radiating the heat of the host to the environment through the host casing, thereby accelerating the heat dissipation of the host. The user can switch the working mode of the cooling fan by pressing the mode switch and check the current working status of the cooling fan through the mode indicator light.
[0046] In summary, this utility model's hard drive enclosure, in addition to its basic functions of accommodating a hard drive and providing an interface, also features magnetic fixation, auxiliary heat dissipation, data cable provision, and storage of male connectors, thus simultaneously meeting multiple user needs. In an example involving gamers, who have high requirements for storage capacity, grip comfort, and heat dissipation capabilities of electronic devices, this utility model's portable hard drive can expand the storage capacity of electronic devices, automatically attach to the back of the device, and assist in heat dissipation, thus simultaneously satisfying multiple needs of gamers and demonstrating good practicality and broad market prospects.
