Description

Foldable electronic device Technical Field The present application relates to the field of electronic devices, and in particular, to foldable electronic devices. Background Some multi-fold folding devices, such as tri-fold devices, require two or more folds. In use, the folding device can be folded to a required fully folded state by folding the machine bodies in sequence according to a set sequence. However, the folding apparatus of the known art is relatively prone to the problem that it is folded in a wrong order in use and cannot be folded normally to the desired fully folded state. Disclosure of Invention The present application provides a foldable electronic device to solve the problem that the folding device in the known art is relatively easy to fold in wrong order in use. An embodiment of the application provides foldable electronic equipment, which comprises a first machine body, a second machine body, a third machine body, a first rotating shaft assembly and a second rotating shaft assembly. The second body is arranged between the first body and the third body. The first body is provided with a first magnetic piece. The first rotating shaft assembly is rotatably connected between the first machine body and the second machine body. The second rotating shaft assembly is rotatably connected between the second machine body and the third machine body. The second rotating shaft assembly comprises a locking mechanism, and the locking mechanism is provided with a magnetic lock catch. The first magnetic piece and the magnetic lock catch correspond to each other along the circumferential direction, so that the first magnetic piece can be close to or far away from the magnetic lock catch along with the folding or unfolding of the first machine body relative to the second machine body, and the third machine body and the second machine body are prevented from being folded relatively through the second rotating shaft assembly. When the first machine body and the second machine body are in an unfolding state, the first magnetic piece is far away from the magnetic lock catch, the magnetic lock catch is in a first position, and the locking mechanism locks the second rotating shaft assembly. When the first machine body and the second machine body are in a folding state, the first magnetic piece is close to the magnetic lock catch so as to drive the magnetic lock catch to move to a second position, so as to unlock the second rotating shaft assembly, and allow the third machine body and the second machine body to be folded relatively through the second rotating shaft assembly. When the first machine body is folded to a position overlapped with the second machine body, the first magnetic piece moves to a position close to the magnetic lock catch so as to drive the magnetic lock catch to move, and then the second rotating shaft assembly is unlocked, and at the moment, the third machine body can be folded relative to the second machine body through the second rotating shaft assembly. Namely, the foldable electronic equipment can ensure that the foldable electronic equipment is folded according to the sequence of folding the first machine body first and then folding the third machine body through the first magnetic piece and the magnetic lock catch corresponding to the positions, so that the problems possibly caused by folding the third machine body first and then folding the first machine body are avoided, such as damage caused by mechanical interference, incapability of being folded in place correctly and the like. For example, a wrong folding sequence may damage the folding screen or the spindle assembly (e.g., the first spindle assembly). In one possible embodiment, the second spindle assembly further includes a first member and a second member that are relatively loose-fitting. The locking mechanism is matched with the first component and the second component, when the magnetic lock catch is in the first position, the magnetic lock catch locks relative movement between the first component and the second component so as to lock rotation of the second rotating shaft assembly, and when the magnetic lock catch is in the second position, the magnetic lock catch unlocks relative movement between the first component and the second component so as to unlock rotation of the second rotating shaft assembly. In this embodiment, through the first mechanism and the second mechanism of locking mechanism cooperation second pivot subassembly for locking mechanism can set up on the second pivot subassembly, and need not occupy the space of second organism, also need not change the original structure and the spatial arrangement of second organism. In one possible implementation, the second rotating shaft assembly comprises a second middle beam, a second swing arm and a second connecting block, wherein one end of the second swing arm is movably connected with the second middle beam, the other end of the second swing arm is movably con
