A new patent for the hinge of the Honor foldable machine is released, solving the problems of unstable damping and poor opening and closing feel

According to news from this site on January 22, Honor Terminal Co., Ltd. announced a new patent for the hinge of a folding screen mobile phone "Rotating mechanism and foldable electronic device", 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 abstract is attached to this site:

1. This application provides a rotating mechanism and a foldable electronic device.

2. The rotating mechanism includes:

   • base
   • first fixed frame
   • first damping swing arm
   • first damping structure
3. One end of the first damping swing arm is rotationally connected to the base, and the other end is connected to the base. The first fixed frame is slidingly connected.

4. The first damping structure includes:

   • The first elastic member
   • The first pressure block, installed on the first damping swing arm

5. The first connecting rod:

   • One end and the first pressure block Rotating connection
   • The other end is rotatably connected to the first fixed frame

6. When the rotating mechanism is unfolded and folded:

   • The length direction of the first connecting rod intersects with the length direction of the base
   • The first elastic member is elastically compressed
   • The first connecting rod resists the first pressure block
   • The first pressure block resists the first damping swing arm
   • The first damping swing arm resists the first fixed frame, giving damping force
7. This rotating mechanism solves the problem of existing The technology’s damping force is unstable and the opening and closing feel is poor.

   

   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 of the damping structures in the existing technology 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, which makes the damping force provided by the concave cam unstable, which in turn affects the opening and closing of the folding machine. Feel.

The above is the detailed content of A new patent for the hinge of the Honor foldable machine is released, solving the problems of unstable damping and poor opening and closing feel. For more information, please follow other related articles on the PHP Chinese website!
