Description

Technical Field

[0002] In this era of booming information technology, portable computers have become quite popular in people's work and life. Lightweight and thinner and more intelligent operation are the development trends of portable computers. At the same time, with the continuous improvement of people's living standards, people's awareness of personal privacy and data security is constantly improving, so higher requirements are also put forward for the safety of portable computers.

[0003] Portable computers are usually equipped with built-in cameras to provide users with various conveniences, such as video communication, webcasting, and surveillance equipment. The opening and closing of the camera of a portable computer is usually controlled by software and can be achieved by clicking on a desktop menu or application. However, using a mouse or touchpad to click and trigger the camera often takes a relatively long time and the camera cannot be turned on or off immediately.

[0004] Moreover, with the development of network communication technology, the networking function of cameras has been continuously enhanced and gradually combined with cloud technology. The camera of a portable computer can be turned on and off through remote operation software. Although this brings convenience to people's use, there is a risk of the camera being maliciously remotely controlled by others, leading to the leakage of user privacy.

[0005] In order to prevent the camera from being remotely controlled by others and causing people's privacy to be leaked, some portable computers are equipped with physical shielding mechanisms, such as shielding plates and shielding covers, etc. When the camera is not in use, the shielding mechanism is located in front of the camera to physically shield the camera. When the camera is in use, the shielding mechanism is moved away so that the camera can shoot normally, thereby ensuring the safety of the camera. However, when the physical shielding mechanism is set, the camera is usually located behind the shielding mechanism, which is equivalent to adding another layer of shielding body to the lens of the camera, which increases the thickness of the portable computer. In addition, the shielding mechanism itself has many parts and a complex structure, and occupies a large space. It not only destroys the appearance style of the portable computer, but also does not meet the requirements of the development of portable computers to be thin and light and intelligent, and the user experience is not high.

[0024] In order to further illustrate the technical means and effects adopted by the present invention, the preferred embodiments of the present invention and the accompanying drawings are described in detail below.

[0025] like Figure 1-Figure 4 As shown, the utility model provides a portable computer, including a body 1 and a camera module 30, a gesture sensing module 40, a control unit 50 and a circuit switch 60 arranged on the body 1. The camera module 30 includes a camera 31 and a circuit board 32, and the circuit board 32 is provided with a driving circuit 33 of the camera 31. The gesture sensing module 40 is connected to the control unit 50, and the control unit 50 is connected to the driving circuit 33 via the circuit switch 60. Among them, the gesture sensing module 40 is used to sense the movement direction of the user's hand within a predetermined distance and generate a corresponding sensing signal, and transmit the sensing signal to the control unit 50; the control unit 50 controls the circuit switch 60 to be turned on or off according to the received sensing signal, so that the driving circuit 33 turns on or off the camera 31.

[0026] Therefore, based on the settings of the gesture sensing module 40, the control unit 50 and the circuit switch 60, the portable computer of the utility model can realize the opening and closing of the camera by sensing the user's gesture, which is convenient for opening and closing the camera and can ensure the safe use of the camera, making the operation of the portable computer more intelligent and improving the user experience.

[0027] Specifically, the sensing signal generated by the gesture sensing module 40 sensing that the movement direction of the user's hand within the predetermined distance is a first movement direction is a first sensing signal, and the control unit 50 controls the circuit switch 60 to be turned on according to the first sensing signal, so that the drive circuit 33 turns on the camera 31; the sensing signal generated by the gesture sensing module 40 sensing that the movement direction of the user's hand within the predetermined distance is a second movement direction is a second sensing signal, and the control unit 50 controls the circuit switch 60 to be turned off according to the second sensing signal, so that the drive circuit 33 turns off the camera 31; wherein, the first movement direction is opposite to the second movement direction.

[0028] In a preferred embodiment, the gesture sensing module 40 may include a first infrared sensor 41, a second infrared sensor 42 and a computing circuit 43, wherein the first infrared sensor 41 and the second infrared sensor 42 are connected to the computing circuit 43, and the computing circuit 43 is connected to the control unit 50. The body 1 is provided with a first through hole 21 and a second through hole 22 corresponding to the first infrared sensor 41 and the second infrared sensor 42, respectively. The first infrared sensor 41 is used to sense the user's hand within the predetermined distance, and outputs a first signal to the computing circuit 43 when sensing the user's hand; the second infrared sensor 42 is used to sense the user's hand within the predetermined distance, and outputs a second signal to the computing circuit 43 when sensing the user's hand; the computing circuit 43 generates the first sensing signal or the second sensing signal according to the sequence and time difference of the first signal and the second signal.

[0029] In a specific implementation, the first infrared sensor 41 and the second infrared sensor 42 can be arranged on the body 1 of the portable notebook of the utility model at a certain distance, for example, arranged in a left-right arrangement on the portable notebook, and sense the user's hand through the first through hole 21 and the second through hole 22 correspondingly arranged on the body 1.

[0030] When the user's hand slides from left to right within the predetermined distance from the first infrared sensor 41 and the second infrared sensor 42, the first infrared sensor 41 on the left side senses the user's hand first and outputs a first signal to the operation circuit 43; the second infrared sensor 42 on the right side senses the user's hand later and outputs a second signal to the operation circuit 43. The operation circuit 43 amplifies, filters, linearizes, and performs analog-to-digital conversion on the time difference between the first signal and the second signal to generate the first sensing signal, and transmits the first sensing signal to the control unit 50. The control unit 50 controls the circuit switch 60 to turn on according to the first sensing signal, so that the drive circuit 33 turns on the camera 31.

[0031] When the user's hand slides from right to left within the predetermined distance from the first infrared sensor 41 and the second infrared sensor 42, the second infrared sensor 42 on the right side senses the user's hand first and outputs the second signal to the operation circuit 43; the first infrared sensor 41 on the left side senses the user's hand later and outputs the first signal to the operation circuit 43.

The control unit 50 controls the circuit switch 60 to be disconnected according to the second sensing signal, so that the drive circuit 33 turns off the camera 31.

[0032] Thus, the portable computer of the present invention can control the camera 31 or turn off the camera 31 by sensing the movement direction of the user's hand within a predetermined distance through the gesture sensing module 40. The predetermined distance can be set according to the actual needs of the user, for example, it can be 100 mm. It is noted here that the specific processing process of the time difference between the first signal and the second signal by the operation circuit 43 is easy to implement for ordinary technicians in this technical field, so it is not repeated here.

[0033] The specific positions of the gesture sensing module 40, especially the first infrared sensor 41 and the second infrared sensor 42 on the main body 1, can be set in accordance with the overall design of the portable computer and the convenience of the user.

[0035] The camera module 30 is arranged in the display module 20, the camera 31 of the camera module 30 and the gesture sensing module 40 are arranged on the circuit board 32 of the camera module 30, and the first infrared sensor 41 and the second infrared sensor 41 of the gesture sensing module 40 are located at opposite ends of the circuit board 32.

[0038] In a preferred embodiment, the camera module 30 may further include an LED light 34, which is disposed on the circuit board 32 and connected to the drive circuit 33. The drive circuit 33 turns on the LED light 34 when the camera 31 is turned on, and turns off the LED light 34 when the camera 31 is turned off. That is, the LED light 34 is used to indicate whether the camera 31 is in the on state or in the off state. The front frame 24 of the display module 20 is also provided with a fourth through hole 27 corresponding to the LED light 34.

[0039] The host module 10 includes a housing 11 and a mainboard 12 disposed in the housing 11 . The control unit 50 and the circuit switch 60 are disposed on the mainboard 12 .

[0040] The driving circuit 33 of the camera module 30 and the gesture sensing module 40 are arranged on the circuit board 32, and the circuit board 32 is connected to the corresponding connector of the main board 12 through wires, so as to realize the communication connection between the gesture sensing module 40 and the control unit 50 and the communication connection between the driving circuit 33 and the circuit switch 60, and the necessary electrical connection between the driving circuit 33 and the gesture sensing module 40 and the main board 12.

[0041] In this way, Figure 1 As shown, when the user's hand is in front of the display module 20 and within the predetermined distance from the first infrared sensor 41 and the second infrared sensor 42, and slides from left to right, the first infrared sensor 41 and the second infrared sensor 42 can successively sense the user's hand and output the first signal and the second signal to the operation circuit 43, so that the operation circuit 43 generates the first sensing signal and transmits it to the control unit 50, and the control unit 50 controls the circuit switch 60 to be turned on, so that the drive circuit 33 turns on the camera 31 and turns on the LED light 34; when the user's hand is in front of the display module 20 and within the predetermined distance from the first infrared sensor 41 and the second infrared sensor 42, and slides from right to left, the second infrared sensor 42 and the first infrared sensor 41 successively sense the user's hand and output the second signal and the first signal to the operation circuit 43, so that the operation circuit 43 generates the second sensing signal and transmits it to the control unit 50, and the control unit 50 controls the circuit switch 60 to be turned off, so that the drive circuit 33 turns off the camera 31 and turns off the LED light 34.

[0042] As can be seen from the above description, the portable computer of the utility model can realize the opening and closing of the camera by sensing the user's gesture through the setting of the gesture sensing module 40, the control unit 50 and the circuit switch 60, which is convenient for opening and closing the camera and can ensure the safety of the camera, solves the problem of relatively long operation time and easy leakage of user privacy in the prior art of the camera switch through software, and makes the operation of the portable computer more intelligent. Moreover, the setting of the gesture sensing module 40, the control unit 50 and the circuit switch 60 of the portable computer of the utility model requires little space, especially, the gesture sensing module 40 is set on the circuit board 32 of the camera module 30, and the control unit 50 and the circuit switch 60 are set on the main board 12, which has almost no effect on the appearance and thickness design of the portable computer, and is more in line with the requirements of thin and light portable computers.

[0043] In a preferred embodiment, the control unit 50 is an embedded controller EC, and the circuit switch 60 is a power switch chip.

[0044] Furthermore, as a camera auxiliary switch mode, the portable computer of the present utility model can also control the opening and closing of the camera 31 by setting a mechanical switch 70. Figure 1 , Figure 2 , Figure 4 As shown, the mechanical switch 70 is disposed on the mainboard 12 of the host module 10 and exposed on the surface of the housing 11 through the mounting hole 13 disposed on the housing 11 corresponding to the mechanical switch 70.

[0045] In this way, through the setting of the mechanical switch 70 , the user can manually turn on or off the camera 31 by operating the mechanical switch 70 .

[0046] Preferably, the mechanical switch 70 is a toggle switch ( Figure 2 The switch body of the toggle switch (arranged on the main board 12) and the button cap used to be sleeved on the switch body are arranged separately. The structure of the toggle switch is well known to ordinary technicians in this technical field and will not be described in detail here. Figure 5As shown, in a preferred embodiment, the control unit 50 is an embedded controller EC, and the circuit switch 60 is a power switch chip, whose model can be G524B1T11U.
