Rotating shaft mechanism and foldable electronic device

A foldable electronic device, comprising:

• a rotating shaft mechanism comprising a base and a rotating assembly that are rotatably connected to each other, wherein the rotating assembly comprises:
• a support, spaced apart from the base;
• a linkage member, arranged between the base and the support;
• wherein the linkage member comprises a body and a driving portion provided at the body, one end of the body being rotatably connected to the base, another end of the body being slidably connected to the support;
• and
• a guide member, comprising a connecting portion and a guiding portion, wherein the connecting portion is arranged at one side of the support and is rotatably connected to the support, the guiding portion is arranged between the connecting portion and the support and is slidably connected to the driving portion of the linkage member;
• a first housing, connected to the support;
• a second housing, connected to the base;
• and
• a foldable screen, connected to the first housing and the second housing, and stacked over the guide member.

A foldable electronic device, comprising:

• a rotating shaft mechanism comprising a base and two rotating assemblies that are rotatably connected to two opposite sides of the base, respectively, wherein each rotating assembly comprises:
• a support, spaced apart from the base;
• a linkage member, arranged between the base and the support;
• wherein the linkage member comprises a body and a driving portion provided at the body, one end of the body being rotatably connected to the base, another end of the body being slidably connected to the support;
• and
• a guide member, comprising a connecting portion and a guiding portion, wherein the connecting portion is arranged at a side of the support and is rotatably connected to the support, the guiding portion is arranged between the connecting portion and the support and is slidably connected to the driving portion of the linkage member;
• a first housing, connected to the support of one of the two rotating assemblies;
• and
• a second housing, connected to the support of the other one of the two rotating assemblies.
