However, during the ICU visit, the patient may have difficulty moving, and after a small movement due to illness, the camera cannot be aligned with the patient's face again, and the patient's face cannot be automatically tracked in the center of the screen. Moreover, during use, the terminal screen may suddenly drop due to mechanical loosening, causing harm to the patient. In addition, it is not convenient to adjust the distance between the terminal screen and the patient and the output volume according to the actual situation.

[0014] The present application has the following advantages:

[0015] 1. This invention uses a linear drive starting mechanism to control the lifting mechanism to achieve lateral displacement, thereby adjusting the left and right positions of the display terminal. This allows for lateral adjustment of the display terminal according to the patient's needs. Simultaneously, when the distance to the display terminal is increased, the linear drive starting mechanism can also control the automatic volume adjustment structure to adjust the volume of the display terminal, increasing the volume to facilitate the patient's reception of video and audio. Conversely, it can automatically decrease the volume to avoid the loud volume affecting the patient's hearing. At the same time, the lifting mechanism can adjust the vertical position of the display terminal, and together with the multi-position adjustment mechanism, the placement angle of the display terminal can be adjusted, so that the display terminal and camera can achieve multi-position adjustment, thereby meeting the daily use needs of patients in various lying positions.

[0016] 2. When the accelerometer detects the display terminal falling rapidly, the present invention can convert the acceleration signal of the falling display terminal into an electrical signal to control the alarm for audible and visual alarm, so that relevant personnel can detect and deal with it in time. When the display terminal falls, it can quickly drag the second rope downward. The second rope pulls the reel and drives the second shaft to move rapidly. Due to the centrifugal force of the second shaft, the locking block overcomes the elastic force of the second spring and is thrown into the locking groove of the locking plate. At this time, the locking block and the locking groove can be locked by tightening force, which can play a locking role and avoid the display terminal falling directly and causing damage or injury to patients.

[0017] 3. In this invention, the screw is driven to rotate by the first motor, which causes the screw to move the threaded frame to the right. When the contact block presses the switch, the switch controls the electric hydraulic rod to start, which in turn controls the telescopic frame to retract upward, thereby driving the display terminal to move upward. At the same time, the display terminal continues to move upward, so that the display terminal corresponds to the right side wing plate of the mounting bracket and enters the right side wing plate of the mounting bracket, thus providing storage and protection for the display terminal during use.
