[0002] In this era of diverse information technologies, electronic computers, as office and entertainment devices, have become quite popular and are an indispensable tool in people's daily work and life. Therefore, electronic computers usually store a large amount of users' work materials and personal documents. To ensure that the users' work materials and personal documents are not leaked, the security of using electronic computers is particularly important. In addition to ensuring the security when the electronic computer is turned on, it is also very important to protect the documents displayed on the screen when the user leaves the electronic computer briefly.
[0003] Currently, during the use of an electronic computer, the security of turning on the electronic computer can be guaranteed by setting a startup password, and the security of the information presented on the electronic computer screen can also be guaranteed by setting a screen saver or entering a screen-off state when the user does not operate the electronic computer for a certain period of time. However, for the former, the password can be tried wrong unlimited times, and the power supply of the electronic computer will not be disconnected, and the startup password is also very easy to be changed; for the latter, it cannot be ensured that the screen is automatically turned off and locked after the user leaves the electronic computer. Moreover, if the set time is too long, it will not play an effective protective role, and if the set time is too short, it will affect the normal use of the user. It can be seen that the existing protection methods cannot effectively guarantee the security of using the electronic computer.
[0004] In particular, as a portable personal computer, laptop computers are being used more and more widely, and more and more users are used to using laptop computers for data processing and storage.

[0022] To further elaborate on the technical means and effects adopted by the present utility model, the following provides a detailed description in conjunction with the preferred embodiments of the present utility model and their accompanying drawings.
[0023] The present utility model provides an electronic computer, which includes a host module, a display module, a camera module, and a status hold switch for user operation. Among them, the display module is electrically connected to the host module. The host module includes a body and a power module and a main board disposed in the body. A control unit is provided on the main board, and the control unit is electrically connected to the power module, the camera module, the status hold switch, and the display module. Among them, when the camera module detects that the user leaves a preset usage position when the electronic computer is in a working state, it sends a departure warning signal to the control unit. The control unit receives the departure warning signal and detects the switch state of the status hold switch. When the status hold switch is in an off state, it controls the display module to turn off the screen and the electronic computer to enter a power-saving and safe mode; when the status hold switch is in a closed state, it keeps the electronic computer in the working state, or controls the display module to turn off the screen and the electronic computer to enter a power-saving and safe mode after a set time.
[0024] Taking the electronic computer as a laptop computer as an example below, the electronic computer of the present utility model is described in detail. As Figure 1 and Figure 2 shown, the electronic computer of the present utility model includes a host module 10, a display module 20, a camera module 30, and a status hold switch 40 for user operation. Among them, the display module 20 is rotatably connected to the host module 10 relative to the host module 10.
[0025] The host module 10 includes a body 11 and a power module 12 and a main board (not shown in the figure) disposed in the body 11. Referring to Figure 3 shown, a control unit 14 is provided on the main board, and the control unit 14 is electrically connected to the power module 12, the camera module 30, the status hold switch 40, and the display module 20.
[0026] Among them, when the camera module 30 detects that the user leaves a preset usage position when the electronic computer is in a working state, it sends a departure warning signal to the control unit 14. The control unit 14 receives the departure warning signal and detects the switch state of the status holding switch 40. When the status holding switch 40 is in an open state, it controls the display module 20 to turn off the screen and the electronic computer to enter a power-saving and safe mode; when the status holding switch 40 is in a closed state, it keeps the electronic computer in the working state, or controls the display module 20 to turn off the screen and the electronic computer to enter a power-saving and safe mode after a set time.
[0027] Thus, when the electronic computer of the present invention is in a working state and the camera module 20 detects that the user leaves a preset usage position, the control unit 14 can not only control the display module 20 to turn off the screen and the electronic computer to enter a power-saving and safe mode, but also, according to the user's setting of the status holding switch 40, choose to immediately control the display module 20 to turn off the screen and the electronic computer to enter a power-saving and safe mode, or control the display module 20 to turn off the screen and the electronic computer to enter a power-saving and safe mode after a set time, or keep the working state. That is to say, before leaving the preset usage position, the user can, by operating the status holding switch 40, make the display module 20 immediately turn off the screen and the electronic computer immediately enter a power-saving and safe mode after leaving the preset usage position, or the display module 20 turns off the screen and the electronic computer enters a power-saving and safe mode after a set time, or keeps the working state.
[0028] In this way, the electronic computer of the present invention can not only ensure the usage safety after the user leaves the electronic computer, but also effectively guarantee the usage safety of the electronic computer (especially a laptop computer) in a timely manner according to the user's operation when the user leaves.
[0029] Specifically, when the status holding switch 40 is in a closed state, whether the control unit 14 keeps the electronic computer in the working state or controls the display module to turn off the screen and the electronic computer to enter a power-saving and safe mode after a set time can be determined by the setting of the control unit 14.
[0030] In addition, by setting the status retention switch 40, the electronic computer can also implement the above two working modes simultaneously. In one embodiment, the status retention switch 40 has a first closed state and a second closed state. When the camera module 30 detects that the user leaves the preset usage position when the electronic computer is in the working state, it sends a departure warning signal to the control unit 14. The control unit 14 receives the departure warning signal and detects the switch state of the status retention switch 40. When the status retention switch 40 is in the first closed state, after a set time, it controls the display module 20 to turn off the screen and the electronic computer to enter the power-saving and safe mode. When the status retention switch 40 is in the second closed state, it keeps the electronic computer in the working state and does not enter the state where the display module 20 turns off the screen and the electronic computer enters the power-saving and safe mode. At this time, the status retention switch 40 can adopt a multi-position switch to achieve different closed states.
[0031] Specifically, the status retention switch 40 is exposed on the surface of the electronic computer for the user to perform pressing or touching operations. In the embodiments as Figure 1 and Figure 2 shown, the status retention switch 40 is arranged on the main board and is exposed on the surface of the laptop through the through hole 15 provided on the body 11 corresponding to the status retention switch 40 for the user to perform pressing operations. The status retention switch 40 can be a mechanical switch or an electronic switch.
[0032] The camera module 50 is arranged in the display module 20, and the display module 20 is provided with a first through hole 25 corresponding to the camera module 50.
[0033] Furthermore, a face recognition unit 16 electrically connected to the control unit 14 is also arranged on the main board of the electronic computer of the present utility model for face recognition.
[0034] Specifically, the control unit 14 receives the start instruction transmitted by the power supply module 12 and sends a shooting instruction to the camera module 30. The camera module 30 takes an image according to the shooting instruction and transmits the image to the control unit 14. The control unit 14 controls the face recognition unit 16 to perform face recognition on the image. When the recognition result of the face recognition unit 16 for face recognition is a preset legal user, it transmits a legal signal to the control unit, and the control unit 14 controls the electronic computer to enter the working state. When the recognition result of the face recognition unit 16 for face recognition is an illegal user, it transmits an illegal signal to the control unit 14, and the control unit 14 controls the electronic computer to enter the power-off state.
[0035] Specifically, when the electronic computer of the present utility model is powered on and started, the power supply module 12 receives an input instruction from the user to generate a start instruction, and transmits the start instruction to the control unit 14. When the control unit 14 receives the start signal, it immediately controls the camera module 30 and the face recognition unit 16 to perform face recognition on the user. When it is recognized and confirmed that the user is a preset legal user, the electronic computer enters the working state; if it is recognized and confirmed that the user is not a preset legal user, that is, an illegal user, the control unit 14 directly controls the electronic computer to enter the power-off state.
[0036] The above process is not limited to the power-on and start process of the electronic computer of the present utility model, and can also be applied to the process of the electronic computer of the present utility model switching from the power-saving and safe mode to the working state. That is to say, when the electronic computer of the present utility model wants to switch from the power-saving and safe mode to the working state, the power supply module 12 can also generate the start instruction according to the input instruction of the user, and transmit the start instruction to the control unit 14. When the control unit 14 receives the start signal, it also executes the above recognition and confirmation process, which will not be elaborated here.
[0037] Therefore, when the electronic computer of the present utility model is powered on and started by the user and when the user returns to the side of the electronic computer and wants to make the electronic computer re-enter the working state from the power-saving and safe mode, it can perform face recognition on the user. Only when it is recognized and confirmed that the user is a preset legal user, will it enter the working state. Other illegal users cannot make the electronic computer powered on and enter the working state, thereby further improving the use safety of the electronic computer.
[0038] Further, the electronic computer of the present utility model may further include an infrared detection module 50, and the infrared detection module 50 is electrically connected to the control unit 14. The control unit 14 receives the start instruction transmitted by the power supply module 12 and sends a detection instruction to the infrared detection module 50. The infrared detection module 50 detects whether there is a human body at the usage position according to the detection instruction of the control unit 14, and sends a notification signal to the control unit 14 when it detects that there is a human body at the usage position. The control unit 14 receives the notification signal and sends a shooting instruction to the camera module 30. The camera module 30 shoots an image according to the shooting instruction and transmits the image to the control unit 14, and the control unit 14 controls the face recognition unit 16 to perform face recognition on the image. When the recognition result of the face recognition by the face recognition unit 16 is a preset legal user, the face recognition unit 16 transmits a legal signal to the control unit 14, and the control unit 14 controls the electronic computer to enter the working state; when the recognition result of the face recognition by the face recognition unit 16 is an illegal user, the face recognition unit 16 transmits an illegal signal to the control unit 14, and the control unit 14 controls the electronic computer to enter the power-off state.
[0039] Thus, when the control unit 14 receives the start instruction transmitted by the power supply module 12, it first sends a detection instruction to the infrared detection module 50. The infrared detection module 50 detects whether there is a human body at the usage position. In the case of the presence of a human body, the control unit 14 then controls the camera module 30 and the face recognition unit 16 to perform face recognition on the user.
[0040] In another embodiment, in the working state of the electronic computer, the infrared detection module 50 may detect whether there is a human body at the usage position according to a preset time or frequency, and send a notification signal to the control unit 14 when it detects that there is a human body at the usage position. The control unit 14 receives the notification signal and sends a shooting instruction to the camera module 30. The camera module 30 shoots an image according to the shooting instruction and transmits the image to the control unit 14, and the control unit 14 controls the face recognition unit 16 to perform face recognition on the image. When the recognition result of the face recognition by the face recognition unit 16 is a preset legal user, the face recognition unit 16 transmits a legal signal to the control unit 14, and the control unit 14 controls the electronic computer to be in the working state; when the recognition result of the face recognition by the face recognition unit 16 is an illegal user, the face recognition unit 16 transmits an illegal signal to the control unit 14, and the control unit 14 controls the electronic computer to enter the power-off state.
[0041] Therefore, during the operation of the electronic computer, it can authenticate its user at a preset interval. Moreover, during the operation of the electronic computer, the infrared detection module 50 remains in the working state, and the camera module 30 starts to work only when the infrared detection module 50 detects a human body at the usage position. This can greatly save the power of the electronic computer and extend the service life of the camera module 30.
[0042] In the embodiments such as Figure 1 and Figure 2 shown, the display module 20 of the electronic computer of the present invention includes a front frame 21, a rear shell 22, and a display screen 23 located between the front frame 21 and the rear shell 22. The display screen 23 is installed in the rear shell 22, and the front frame 21 is installed on the rear shell 22. A groove 24 is provided on the rear shell 22. The groove 24 is located above the display screen 23. The camera module 30 and the infrared detection module 50 are installed in the groove 24. The front frame 21 is respectively provided with a first through hole 25 and a second through hole 26 corresponding to the camera module 30 and the infrared detection module 50.
[0043] In another embodiment, as described above, the camera module 30 is provided in the display module 20, and the display module 20 is provided with a first through hole 25 corresponding to the camera module 30; the infrared detection module 50 is provided in the main body 11, and a second through hole corresponding to the infrared detection module 50 is correspondingly provided on the main body 11.
[0044] In summary, through the settings of the camera module and the status retention switch, the electronic computer of the present utility model can detect when the user leaves the usage position. When it detects that the user has left the usage position, it can not only control the display module to turn off the screen and the electronic computer to enter the power-saving and safe mode, but also, according to the user's setting of the status retention switch, choose to immediately or after a set time, control the display module to turn off the screen and the electronic computer to enter the power-saving and safe mode. Of course, it can also maintain the working state unchanged. Thus, it can not only ensure the usage safety after the user leaves the electronic computer, but also effectively guarantee the usage safety of the electronic computer in a timely manner according to the user's operation when the user leaves. Further, through the settings of the camera module and the face recognition unit, when the control unit receives a startup instruction from the power module, the electronic computer of the present utility model can perform face recognition on the user. Only when it is recognized and confirmed that the user is a preset legitimate user can it enter the working state, and no other illegal users can turn on the electronic computer to enter the working state, thereby further enhancing the usage safety of the electronic computer. In addition, the electronic computer of the present utility model is further provided with an infrared detection module to detect the human body at the usage position and perform face recognition after detecting the presence of a human body, further optimizing the authentication of the user by the electronic computer during startup and operation.
[0045] The electronic computer of the present utility model is not limited to the laptop computer listed in the embodiments, and can also be applicable to desktop computers, all-in-one computers, etc.
[0046] As described above, for those of ordinary skill in the art, various corresponding changes and deformations can be made according to the technical solutions and technical concepts of the present utility model, and all such changes and deformations should fall within the protection scope of the claims of the present utility model.
