The double-layer structure of the fingerprint sensor and the flash memory chip U _2a ( U _2b Both are connected to the USB controller U ₃ , and the USB connector is double-layered to the PCB board 2 for connection with the USB controller U ₃ .

该指纹传感器用于感应用户手指移动方向及点击动作等类似于鼠标操控的信号，同时也能通过被动式扫描获取用户指纹的数字化图像信号。具有实现该功能能力的指紋传感器典型型号为由 ATRU A公司生产的 ATW 31 X , 其性能稳定、优越性较好。 The fingerprint sensor is used to sense a mouse-like signal such as a user's finger movement direction and a click action, and can also obtain a digitized image signal of the user's fingerprint through passive scanning. A typical model of the fingerprint sensor capable of realizing this function is the ATW 31 X manufactured by ATRU A, which has stable performance and superiority.

该闪存芯片 U_2a、 U_2b用于存储用户资料和应用程序，两块闪存芯片在 U盘初始化后均被分区形成公开区和经指纹认证后允许访问读写操作的保密区两部分，供用户选择性地进行资料存取操作。闪存芯片 U_2a还进一步划分形成只读区和隐藏区两个分区，分别存放软件程序及预设的指纹特征数据。其中的软件程序包括鼠标控制程序 I、指紋识别程序 II、 U盘加密许可访问程序 III、计算机文件和目录加密程序 IV、计算机屏保程序 V、计算机开机安全保护程序 VI , 以及网络账号和密码自动保护程序 VII等扩展性程序。闪存芯片的型号通用性较大，本例中选用的是：三星公司生产的 84b K98G08UB_o 该 USB控制器 U₃主要用于接收信号，并调用软件程序进行运算控制、信号转换，并向 USB接头输出控制信号。本例中，其型号为 PL2520-LPQ64的单片机芯片。 The flash memory chips U _2a and U _{2b are} used for storing user data and application programs. After the U disk is initialized, the two flash memory chips are partitioned into a public area and a secret area that allows access to read and write operations after fingerprint authentication, for the user. Selective data access operations. The flash memory chip U _2a is further divided into two partitions, a read-only area and a hidden area, for respectively storing software programs and preset fingerprint feature data. The software program includes mouse control program I, fingerprint recognition program II, U disk encryption permission access program III, computer file and directory encryption program IV, computer screen saver program V, computer boot security program VI, and automatic protection of network account and password. Extended program such as program VII. Flash memory chip models greater versatility, in the present embodiment is selected: manufactured by Samsung the USB controller 84b K98G08UB _o U ₃ is mainly used for receiving signals, and the calling software program calculates a control signal conversion, to the USB connector Output control signals. In this example, the model is a single chip of PL2520-LPQ64.

该 USB接头 U₄—体化设置于智能闪存 U盘的外壳 1 内，负责整个设备的电源供电，并与 PCB板 2欢层焊接。 The USB connector U ₄ is disposed in the outer casing 1 of the smart flash USB flash drive, and is responsible for power supply of the entire device and soldering with the PCB board 2 .

上述各组成部分在完成 PCB的双层焊装后使用时，将该 USB接头 U₄通过延长线接入计算机的通用串行总线控制器（USB 端口）后，该指紋传感器 Ui首先将感应用户手指移动方向及点击动作等类鼠标操作，并将感应信号传输至 USB控制器 U₃; 然后由该 USB控制器 U₃调用存储在闪存芯片 U_2a只读区内的鼠标控制程序 I , 将指纹传感器 II,的感应信号转换成符合计算机控制语言格式的电信号；接着再由 USB接头 U₄向计算机输出等同鼠标或游戏操纵杆操控的电信号。其中，该指紋传感器用来判断手指点击动作和移动方向的依据是指纹传感器与手指的接触时间、连续按压次数及位置变化。 When the above components are used after the double-layer soldering of the PCB, the USB connector U _{4 is} connected through the extension cable. After entering the universal serial bus controller (USB port) of the computer, the fingerprint sensor Ui first senses a mouse operation such as a user's finger movement direction and a click action, and transmits the sensing signal to the USB controller U ₃ ; The controller U ₃ calls the mouse control program I stored in the read-only area of the flash chip U _{2a to} convert the sensing signal of the fingerprint sensor II into an electrical signal conforming to the computer controlled language format; and then outputs the USB connector U ₄ to the computer. Equivalent to the electrical signal controlled by the mouse or joystick. The fingerprint sensor is used to determine the finger click action and the moving direction based on the contact time of the fingerprint sensor with the finger, the number of consecutive presses, and the position change.

除上述鼠标操控功能得以实现外，该智能闪存 U盘同样具有指紋加密功能。连接计算机后的智能闪存 U盘，首先该指紋传感器 11,通过被动式滑动扫描获取用户指纹图像并将数字化的图像信号传输至 USB控制器 U₃; 然后由 USB控制器 U₃调用闪存芯片 U 只读区内的指紋识别程序 II及隐藏区内的指纹特征数据进行匹配；最后经匹配认证后由 USB控制器 U₃调用只读区内的 U盘加密许可访问程序 III , 允许对所述闪存芯片 U_2a ( U_2b )保密区的访问读写，但如果经匹配后无法得到认证，则智能闪存 U 盘继续保持对闪存芯片保密区的禁止访问，有效保证了这一分区内资料的安全性。实施例二 In addition to the above mouse control functions, the smart flash USB flash drive also has a fingerprint encryption function. After the computer is connected to the smart flash USB flash drive, the fingerprint sensor 11 first acquires the user fingerprint image through passive sliding scanning and transmits the digitized image signal to the USB controller U ₃ ; then the flash controller U is called by the USB controller U _{3 .} The fingerprint identification program II in the area and the fingerprint feature data in the hidden area are matched; finally, after the matching authentication, the U disk encryption permission access program III in the read-only area is called by the USB controller U _{3 to} allow the flash memory chip U to be _2a ( U _2b ) access and reading in the security zone, but if the authentication cannot be obtained after matching, the smart flash USB disk continues to maintain the forbidden access to the flash chip security zone, effectively ensuring the security of the data in the zone. Embodiment 2

如图 4 所示，是本发明另一实施例的横向剖面示意图。其中与实施例一相似的结构部分本例中不再贅述。结合图 1 中虚线部分及图 4 可以看到，该兼具鼠标功能的智能闪存 U盘还具有一扩展存储容量的闪存芯片 U_2b，该闪存芯片 U_2b主要是针对对存储空间要求较大的特殊用户设置的，贴片焊接在 PCB板 2相对于闪存芯片 U_2a的另一层，并同样与 USB控制器形成连接 ϋ₃。实施例三 4 is a schematic cross-sectional view showing another embodiment of the present invention. The structural part similar to the first embodiment will not be described in detail in this example. As can be seen in the dotted line portion of FIG. 1 and FIG. 4, the flash memory U disk with the mouse function also has a flash memory chip U _2b with an extended storage capacity, and the flash memory chip U _{2b is} mainly for a large storage space requirement. The chip is soldered to another layer of the PCB 2 relative to the flash chip U _2a and is also connected to the USB controller ϋ ₃ . Embodiment 3

如图 5和图 6所示，分别是本发明兼具鼠标功能的智能闪存 U盘演进的原理拓朴图和演进实施例的横向剖面示意图。从图中可见，该智能闪存 U盘透过或穿过外壳 1 , 另接设有一指示光发射单元 U₅。由于 USB接头 U₄是整个闪存 U盘的供能源头，因此为达到简化结构的目的，对该指示光发射单元 U₅的供能同样落在了 USB接头 U₄上。同时，该指示光发射单元 U₅是通过用户手指点击指紋传感器后，由该 USB控制器 U₃响应软件程序的指令触发的，从而实现闪存 U盘的电子教鞭功能化。本实施例其他部分与实施例二均相同，故不再赘述。实施例四 As shown in FIG. 5 and FIG. 6, respectively, it is a schematic diagram of a schematic diagram and a horizontal cross-section of an evolutionary embodiment of a smart flash USB disk evolution of the present invention. As can be seen from the figure, the smart flash USB flash drive passes through or through the outer casing 1 and is additionally provided with an indicator light emitting unit U ₅ . Since the USB connector U ₄ is an energy supply head for the entire flash memory U disk, the power supply to the indicator light emitting unit U ₅ also falls on the USB connector U ₄ for the purpose of simplifying the structure. At the same time, the indicator light emitting unit U ₅ is triggered by the USB controller U _{3 in} response to a software program after the user clicks the fingerprint sensor, thereby realizing the electronic pointer function of the flash memory U disk. The other parts of this embodiment are the same as those of the second embodiment, and therefore will not be described again. Embodiment 4

如图 7 所示，是本发明又一实施例的横向剖面示意图。从图中可以看到，延续了以上三个实施例的共同核心特征，本实施例把实现方法集中到 USB接头 U₄上来，将原本需要通过延长线连接的闪存 U盘变换为将 USB接头采用线圈伸缩式延长线 3收纳在外壳一端的形式。当需要将该闪存 U盘连接至计算机时，只需将 USB接头 U₄延伸拉出即可；使用完毕后又可以方便地将其收纳回去，给用户的携带、使用带来了进一步的方便。 Figure 7 is a schematic cross-sectional view showing still another embodiment of the present invention. As can be seen from the figure, it continues The common core features of the above three embodiments, the embodiment concentrates the implementation method on the USB connector U ₄ , and converts the flash memory U disk that originally needs to be connected by the extension cable to the USB connector to be housed in the outer casing by using the coil telescopic extension cable 3 The form of one end. When the flash USB flash drive needs to be connected to the computer, only the USB connector U ₄ can be extended and pulled out; after use, it can be conveniently stored back, which brings further convenience to the user for carrying and using.

除以上介绍的四个实施例外，本发明还可以有其他多样性的实施方式。例如，该外壳 1 的外形不仅仅局限于图示的矩形立方体，各种便携、美观的外壳结构均可适用于本发明的智能闪存 U盘；而且上述指紋传感器、 USB控制器及闪存芯片均可随着电子元器件的更新换代在型号及容量上有所替换、变化；以及如图 8 所示的指纹传感器设置方向与前述实施例相对垂直，为闪存 U盘在插接计算机背面的 USB端口时提供使用便利性。 In addition to the four embodiments described above, the invention may have other diverse embodiments. For example, the outer shape of the outer casing 1 is not limited to the rectangular cube shown in the drawing, and various portable and beautiful outer casing structures can be applied to the smart flash USB flash drive of the present invention; and the above fingerprint sensor, USB controller and flash memory chip can be used. As the replacement of electronic components is replaced and changed in terms of model and capacity; and the orientation of the fingerprint sensor as shown in FIG. 8 is relatively perpendicular to the foregoing embodiment, when the flash USB flash drive is plugged into the USB port on the back of the computer. Provides ease of use.

通过以上多个实施例介绍，本发明兼具鼠标功能的智能闪存 U 盘的有益效果显而易见：基于闪存 U盘的存储功能，通过一个 USB接头与通用串行总线控制器的连接，实现了闪存、鼠标、游戏操纵杆，甚至电子教鞭的功能整合，为用户携带电脑外设提供了方便，并且节省了计算机设备有限的 USB 端口资源；同时结合指纹加密技术，提高了保存资料及使用电脑的安全性。 Through the above various embodiments, the beneficial effects of the smart flash USB flash drive with the mouse function of the present invention are obvious: Based on the storage function of the flash USB flash drive, the flash memory is realized by connecting a USB connector to the universal serial bus controller. The function integration of mouse, game joystick, and even electronic pointer provides convenience for users to carry computer peripherals, and saves limited USB port resources of computer equipment. At the same time, combined with fingerprint encryption technology, it improves the security of saving data and using computer. .

综上所述，全面展现了本发明设计的结构特征、实施过程及有益效果。但并非以此限制本发明实施方式的多样性。因此，但凡对于以上实施例进行筒单修改或等效替换所形成的技术方案，能够在 U 盘设备上实现鼠标功能，均应视为本发明申请保护的范围内。 In summary, the structural features, implementation process and beneficial effects of the design of the present invention are fully demonstrated. However, the diversity of embodiments of the invention is not limited thereby. Therefore, if the technical solution formed by the modification or equivalent replacement of the above embodiment is implemented, the mouse function can be implemented on the U disk device, which should be regarded as the scope of protection of the present invention.
