Honor Terminal Co., Ltd. announced a new patent for the hinge of a folding screen phone, “Rotating Mechanism and Foldable Electronic Devices”, which can solve the problem of unstable damping force of the rotating mechanism in the existing technology and poor opening and closing feel. technical problem.
A patent summary is attached:
This application provides a rotating mechanism and a foldable electronic device. The rotating mechanism includes a base, a first fixed frame, a first damping swing arm and a first damping structure. One end of the first damping swing arm is rotationally connected to the base, and the other end is slidingly connected to the first fixed frame.
The first elastic member and the first pressure block of the first damping structure are both installed on the first damping swing arm, and the first pressure block is located on one side of the first elastic member. One end of the first connecting rod is rotatably connected to the first pressing block, and the other end is rotatably connected to the first fixed frame. When the rotating mechanism is in the unfolded state and the folded state, the length direction of the first connecting rod intersects the length direction of the base, the first elastic member is elastically compressed, the first connecting rod resists the first pressure block, and the first pressure block resists the first pressure block. A damping swing arm, the first damping swing arm resists the first fixed frame and causes the first fixed frame to receive a damping force.
The rotating mechanism provided by this application can solve the technical problems in the prior art that the damping force of the rotating mechanism is unstable and the opening and closing feel is not good.
It is understood that the rotating mechanism is the core structure to realize the unfolding and folding of the folding machine, and the damping structure can achieve a damping feel. Most damping structures in the prior art provide damping force through concave cams.
The cam in this damping structure is always subject to friction during rotation, and the joint surface of the cam is prone to wear, making the damping force provided by the concave cam unstable, which in turn affects the opening and closing feel of the folding machine.
