Claim:
1. An electronic apparatus, including: a first body, the first body including a touch control unit; a second body; a connection device including: a connection body through which the first body is connected with the second body, wherein, an angle value of the first body relative to the second body can vary by rotating around the connection device; a first torque generator including a first recess member and a first protrusion member interacted with each other to generate a torque and provided inside the connection body; and a second torque generator including a second recess member and a second protrusion member interacted with each other to generate a torque and provided inside the connection body; the first torque generator further includes a first elastic device that can be pressed under the interaction between the first recess member and the first protrusion member, the second torque generator further includes a second elastic device that can be pressed under the interaction between the second recess member and the second protrusion member; wherein, one of the first recess member and second recess member and the respective first protrusion member and second protrusion member is fixedly connected to one of the first body and the second body, and the other of the first recess member and second recess member and the respective first protrusion member and second protrusion member is fixedly connected to the other one of the first body and the second body such that rotation of one of the first body or the second body with respect to the other of the first body or the second body enables the recess member and the protrusion member to interact to generate torque; and wherein when the angle value is in a first preset threshold range, the first torque generator generates a first torque for balancing a second torque generated by a gravitational effect generated by a weight of the first body, and a torque generated by the second torque generator remains zero or constant; and when the angle value is larger than a maximum value of the first preset threshold range, the first torque generator generates a third torque, which is greater than the torque generated by it when the angle value is in the first preset threshold range, and the second torque generator generates a fourth torque, the third torque and the fourth torque balancing a fifth torque generated by a first composite force, wherein, the first composite force is a composition of the gravitational effect and a push force acting on the touch control unit.
