Keyboard supporting pad

The utility model discloses a keyboard supporting pad which comprises a shell, a display module, a control module, an alarm module, two heart rate sensors and two gravity acceleration sensors. The shell is of a hexahedral structure; the top plate of the shell is integrated with the first side surface; the top plate is in radian connection with the first side surface to form a flexible curved surface conforming to human wrist part engineering; the display module is fixedly connected to the outer surface of the top plate of the shell; the control module and the alarm module are fixedly connected to the inner side of a bottom plate of the shell; the heart rate sensor and the gravity acceleration sensor are electrically connected with the control module. The two heart rate sensors are bilaterally symmetrically arranged along the center line of the bottom plate; the two gravitational acceleration sensors are arranged in a bilateral symmetry mode along the center line of the bottom plate. The system can detect and
