Description

Technical Field

[0001] The present invention relates to the field of computer peripherals, and in particular to a USB device storage device with an encryption function. Technical Background

[0002] As USB devices become increasingly powerful and mature, their use has increased. However, as USB devices shrink in size, they are often easily lost. This is especially true when users own multiple USB devices. Due to their size, switching between devices and storing them becomes inconvenient. Furthermore, some USB devices lack encryption, making it difficult to manage access permissions and ensure data security during use.

[0003] To address the aforementioned issues, the present invention provides a USB device storage device with encryption capabilities. Multiple USB devices can be centrally stored and managed. It connects to a computer via an external USB port. Furthermore, the USB device storage device features both mobile app wireless encryption and key encryption. Individual devices within the USB device storage device can be enabled or disabled using a mobile app or a key code set on the device. To achieve the aforementioned effects, the present invention utilizes the following technical solutions. Summary of the Invention

[0004] A USB device storage device with encryption function mainly consists of a functional mainboard, a heat dissipation mainboard connected to the functional mainboard, a shell, a back cover, a hanging ring and a retractable USB connecting cable.

[0005] The shell is provided with heat dissipation holes for heat dissipation, a hanging ring for tying a rope and hanging, and reserved function motherboard button openings, function motherboard indicator light openings, and function motherboard data line lead-out openings.

[0006] The functional motherboard has buttons and LED indicators on its back, and on its front are the main control module, USB hub module, wireless module, encryption module, power module, temperature control module, memory card slot, multiple USB ports for connecting USB devices, pin headers for connecting to the heat dissipation motherboard, and two USB ports for connecting to the retractable USB cable.

[0007] The temperature control module, connected to the main control module, monitors and controls the temperature within the USB device storage device. USB devices generate significant heat during operation, impacting device performance. Therefore, when the temperature control module detects excessive temperature, it sends a signal to the main control module. The main control module then controls the power module to supply power to the heat dissipation motherboard, cooling it down.

[0008] The heat dissipation mainboard houses a heat dissipation module, a battery module, a power interface, and pin headers for connecting to the functional mainboard. The heat dissipation module consists of an upper heat dissipation module and a lower heat dissipation module. Both modules are composed of circuit boards equipped with fans and semiconductor cooling modules.

[0009] The upper and lower heat dissipation modules are then assembled, connected, and secured to the heat dissipation mainboard using screws through pre-reserved openings and screw holes on the circuit board. Finally, the battery module is connected to the corresponding power connectors on the heat dissipation modules via power cables, ultimately providing integrated power to the heat dissipation mainboard.

[0010] The power module, in addition to controlling the power supply of the heat dissipation mainboard, also has the function of controlling the charge and discharge of the battery module on the heat dissipation mainboard and powering the entire machine.

[0011] The encryption module is composed of multiple analog switch chips. When the control pin of the analog switch chip inputs a high or low level, the corresponding group of output pins on the chip can be turned on or off, thereby opening or closing a switch.

[0012] Preferably, the analog switch chip is 74HC1G66GW.

[0013] The retractable USB connecting cable is a common retractable USB data cable currently available on the market.

[0014] The wireless module is a wireless communication module capable of communicating with a mobile phone app. By connecting to the mobile phone app, the phone can communicate with the wireless module. Because the wireless module is connected to the main control module, the main control module can control the opening or closing of a switch in the connected encryption module using commands transmitted from the wireless module. In other words, the corresponding USB interface can be opened or closed through the wireless module, the main control module, and the encryption module through operations on the mobile phone app.

[0015] Preferably, the wireless module is a WIFI module.

[0016] The USB HUB is a USB hub, which is a device that can expand one USB interface into multiple ones and make these multiple interfaces usable at the same time.

[0017] The functional motherboard includes multiple USB interfaces for connecting USB devices, with data pins of some interfaces connected in parallel to a single USB interface, which is one of the interfaces on the functional motherboard used to connect to the retractable USB cable. The other interfaces are USB interfaces extended from the USB HUB module.

[0018] The power supply pins of the multiple USB interfaces are connected to the power supply circuit via an encryption module. The encryption module includes an analog switch chip. The power supply terminal of the USB interface is connected to one end of the analog switch chip, and the other end of the analog switch chip is connected to the power supply. Because the control terminal of the analog switch chip in the encryption module is connected to the main control module, when the main control module outputs a corresponding instruction, it can turn on a circuit corresponding to the chip, thereby connecting the power supply circuit of the corresponding USB interface and making the interface usable.

[0019] Furthermore, the interface distributed on the functional mainboard and connected to the retractable USB cable can power the entire device through the power supply pin of the USB interface of the computer when it is inserted into the computer via the USB cable.

[0020] Furthermore, the power supply pins of the multiple USB interfaces distributed on the mainboard are connected to the power supply circuit via an encryption module. The encryption module is in turn connected to the main control module. When the user enters the correct password using the buttons on the functional mainboard, the user can further select whether to turn a certain USB device on or off using the buttons. When a certain USB interface is selected for opening, the main control module sends an instruction to the encryption module, connecting the power supply pin of the USB interface to the power supply circuit. This interface can then be used normally. Since the data interfaces of some of the USB interfaces on the main control module are connected in parallel, and since the data circuit is shared, only one of these USB interfaces can be opened at a time. When another interface needs to be opened, the current interface needs to be closed. However, the other USB interfaces extended through the USBHUB can be opened and used simultaneously.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] As shown in the accompanying drawings, the present invention primarily comprises a functional motherboard 39, a heat sink motherboard 38 connected to the functional motherboard, a housing 3, a rear cover 8, and a retractable USB cable 7. The housing of the USB device storage device is provided with buttons 4, a status indicator 5, and a battery indicator 6. Before use, open the rear cover 8 of the USB device storage device to reveal the heat sink motherboard 38. The heat sink motherboard 38 and the functional motherboard 39 are connected via pin headers 25. This allows the heat sink motherboard to be easily removed from the functional motherboard. To use the device, first open the rear cover 8 and remove the heat sink motherboard 38. The USB port 14 and memory card holder 13 reserved on the functional motherboard are then visible. The USB port 14 is divided into two parts. One part, which includes the USB port and memory card slot, is extended from the USB HUB module 15. The USB HUB module 15 is connected to one of the ports of the USB port 16, which is connected to the retractable USB cable. The data pins of the other part of the USB port, which is connected to another port of the USB port 16, are shared in parallel with the other port. The power supply pins of these multiple USB ports 14 are connected to the encryption module, which is connected to the main control module. Insert the USB device you want to store and manage into the USB port or install the memory card device into the card holder. Reinstall the heat sink motherboard and back cover. This completes the installation. At this time, if the user presses and holds any button for 3 seconds, the password function is activated. Wait for the password to be entered. After entering the correct password, select the corresponding USB device to be turned on by pressing the button corresponding to the internal USB port. The device is turned on, and the indicator corresponding to LED status indicator 5 lights up to indicate that the corresponding USB device is currently enabled. Connect the USB connector of the retractable USB cable to the computer end to access the corresponding USB device in the USB device storage device.

[0029] Because the USB device storage device's functional mainboard 39 also includes a wireless module 10, stored USB devices can be managed without the need for keystrokes. This wireless module 10 is connected to the main control module 18. Once the user connects to the wireless module through a mobile app, they can enter a password as prompted to enable or disable a specific USB port, thus achieving wireless encryption.

[0030] The functional mainboard also includes a wireless module 10, an encryption module 11, a power module 12, a memory card holder 13, multiple USB ports 14 for connecting to USB devices, a USB hub module 15, a USB port 16 for connecting to a retractable USB cable, a temperature control module 17, and a main control module 18.

[0031] When using the wireless encryption function, the mobile phone app connects to the wireless module 10. The user selects the USB port to be opened or closed on the phone and enters the password as prompted. The wireless module 10 receives the data from the phone and sends it to the main control module 18. The main control module 18 controls the encryption module 11 based on the data content, turning the power supply circuit of the corresponding USB port on or off.

[0032] When the key encryption function is used, the key data is transmitted to the main control module 18 through the relevant operation of the key 4 on the function main board. The main control module 18 controls the encryption module 11 according to the content of the key data to open or close the power supply line of the corresponding USB interface.

[0033] In addition, this USB device storage device with encryption function can automatically dissipate heat during operation to ensure the normal use of USB devices. This function is achieved through the heat dissipation motherboard.

[0034] The heat dissipation mainboard is mainly composed of a lower heat dissipation module 31 and an upper heat dissipation module 21 installed on the heat dissipation mainboard and a battery module 9.

[0035] The upper heat dissipation module further comprises an upper cooling fan 22 and an upper heat dissipation module circuit board 23 on which the upper cooling fan 22 is mounted. The upper cooling fan 22 is bonded to the upper heat dissipation module circuit board 23 with thermally conductive silicone grease. The upper heat dissipation module circuit board 23, on which the upper cooling fan 22 is mounted, also features a power connector 24 for connecting to the lower heat dissipation module circuit board 27, a power interface 42 for connecting to the battery module 9 via the power cable 19, and screw holes 35 for securing the module to the heat dissipation mainboard.

[0036] Furthermore, the lower heat dissipation module 31 is composed of a lower heat dissipation fan 26, a lower heat dissipation module circuit board 27, and a semiconductor refrigeration module 28 with a reserved power interface 29. One side of the lower heat dissipation module circuit board 27 is bonded and fixed to the lower heat dissipation fan 26 by thermal conductive silicone grease, and the other side is bonded and fixed to one side of the semiconductor refrigeration module 28 by thermal conductive silicone grease.

[0037] Furthermore, the lower heat dissipation module circuit board 27 is also provided with an interface 30 corresponding to the power connector 24 of the upper heat dissipation module circuit board, an interface 40 corresponding to the power interface 29 of the semiconductor refrigeration module, and screw holes for fixing to the heat dissipation main board.

[0038] The upper and lower heat dissipation modules are connected and assembled to the heat dissipation mainboard via reserved openings 32, 37 and screw holes 33 on the heat dissipation mainboard. The semiconductor cooling module 28 of the lower heat dissipation module passes through the reserved opening 32 of the heat dissipation mainboard. It is adhered to the side opposite the upper heat dissipation module circuit board 23 using thermally conductive silicone grease. The upper and lower heat dissipation modules are secured to the heat dissipation mainboard using screws through screw holes 33, 35, and 36. This completes the assembly of the upper and lower heat dissipation modules and the heat dissipation mainboard.

[0039] The assembled heat sink mainboard is powered by a power cable 19 that connects the power interface 34 of the battery module 9 to the power interface 42 on the upper heat sink circuit board 21. The reserved power connector 24 on the upper heat sink circuit board 21 connects to the power interface 30 on the lower heat sink circuit board via an opening 37 on the heat sink mainboard 38. The power interface 40 on the lower heat sink circuit board is then connected to the power interface 29 on the semiconductor cooling module 28 via a power cable 41. Finally, the wires 43 on the battery module 9 are connected to the heat sink mainboard. The power supply wires 45 for the upper and lower cooling fans 22 and 26 are connected to the power interface 44 on the heat sink mainboard. This completes the power supply of the entire heat sink mainboard.

[0040] The heat dissipation mainboard is connected to the functional mainboard via pin headers 25. The power module 12 on the functional mainboard not only controls the charging and discharging of the battery module 9, but also cooperates with the main control module 18 and temperature control module 17 to control the cooling system's on and off state. It also provides power to the entire system, including the functional mainboard.
