Description
Technical Field
[0001] The utility model relates to the technical field of computers, in particular to a notebook computer. Background Art
[0002] In this era of diversified information technology, computers have become quite popular as office and entertainment equipment, and their functions are becoming more and more abundant. As a small and easy-to-carry personal computer, laptops are becoming thinner and lighter while also having more and more functions to provide users with various conveniences.
[0003] For the convenience of use, existing laptops are usually equipped with wireless network communication (WiFi) modules, Bluetooth (BlueTooth) modules, cameras, microphones, etc., so as to realize network connection, wireless transmission, video communication, webcasting, remote monitoring and other functions. However, the opening and closing of these modules or devices are completely controlled by software. Once the laptop is invaded by external forces, such as being implanted with malware or hacked, it is easy to cause the WiFi or Bluetooth function to be automatically turned on, resulting in data being stolen, or the camera and microphone being remotely controlled by others, resulting in people's daily life being secretly photographed and privacy being leaked.
[0004] In view of the above-mentioned situations that may lead to data theft or privacy leakage, most laptops can only enhance the security of use by enhancing software control. However, as long as the power is not cut off, there is always the possibility of external intrusion. Some laptops avoid privacy leakage by setting corresponding components for specific functions. For example, a shield is set for the camera. When the camera is not in use, the shield is placed in front of the camera to block the camera. When the camera is in use, the shield is moved away so that the camera can shoot normally to ensure the safety of the camera. However, this shield usually has many parts, a complex structure, and occupies a large space, which does not meet the requirements of the development of thin and light laptops; or, a separate power switch is set for the camera. However, as mentioned above, the existing laptops have various functions. Setting a switch for each functional component will not only make the structure of the laptop more complicated, which is not conducive to its simple and beautiful appearance, but also complicate the operation.
