  • Patent number: 9699934
    Abstract: An electronic apparatus includes a first body; a second body; a connection device including: a connection body through which the first body is connected with the second body; with a first torque generator and a second torque generator provided inside the connection body. When an angle value is in a first preset threshold range, the first torque generator generates a first torque for balancing a second torque generated by gravitation of the first body. When the angle value is larger than a maximum value of the first preset threshold range, the first torque generator generates a third torque 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, which is the composite force of the gravitation of the first body and a push force acting on a touch control unit.
