Referring to fig. 13, fig. 13 is a cross-sectional view of the rotating mechanism 100 shown in fig. 5.
The damper assembly 40 is mounted to the fixed base 10. Wherein, the synchronizing gear 43, the hinge member 1 and the damping member 2 are located in the fixed base 10, and the first damping swing arm 41 and the second damping swing arm 42 are respectively located at two opposite sides of the fixed base 10 in the X direction. The second end 412 of the first damping swing arm 41 is located in the first sliding slot 216 of the first fixing plate 21 and is slidably connected with the first fixing plate 21. The fourth damping swing arm 42 is located in the second sliding slot of the second fixing plate 22 and is slidably connected to the second fixing plate 22. Meanwhile, the first magnetic body 46 is hinged to the hinge member 1, the first hinge member 44 is hinged to the first hinge seat 464, and the second hinge member 45 is hinged to the second hinge seat 465.
When the first fixing plate 21 rotates relative to the fixed base 10, the first damping swing arm 41 is driven to rotate, and the first damping swing arm 41 slides in the first sliding slot 216. Meanwhile, when the first damping swing arm 41 rotates, the first gear 431 is driven to rotate synchronously, so that the second gear 432 is driven to rotate through the third gear 433 and the fourth gear 434, the second damping swing arm 42 is driven to rotate, the second fixing plate 22 is driven to rotate, and the first fixing plate 21 and the second fixing plate 22 are further driven to rotate synchronously.
It should be noted that when the first gear 431 rotates, the first hinge 44 is rotated. When the first hinge 44 rotates, the first protrusion 441 rotates out of the third recess 4642 of the first hinge base 464 to the third protrusion 4641, and then rotates into the third recess 4642 from the third protrusion 4641, so as to repeatedly push the first hinge base 464 to slide along the first fixing rod 481, and drive the first magnetic body 46 to slide, so that the distance between the first magnetic body 46 and the second magnetic body 47 decreases, and the magnetic repulsive force F1 between the first magnetic body 46 and the second magnetic body 47 increases. Meanwhile, when the second gear 432 rotates, the second hinge member 45 is driven to rotate. When the second hinge 45 rotates, the second protrusion 451 rotates out of the fourth recess 4652 of the second hinge seat 465 to the fourth protrusion 4651, and then rotates into the fourth recess 4652 from the fourth protrusion 4651, so as to repeatedly push the second hinge seat 465 to slide along the fourth fixing rod 484, and together with the first hinge seat 464, drive the first magnetic body 46 to slide toward the second magnetic body 47, so that the distance between the first magnetic body 46 and the second magnetic body 47 decreases, and thus the magnetic repulsive force F1 between the first magnetic body 46 and the second magnetic body 47 increases, thereby providing a damping force for the rotation of the first damping swing arm 41 and the second damping swing arm 42. The damping force of first damping swing arm 41 acts on first casing 210 through first fixed plate 21, and the damping force of second damping swing arm 42 acts on second casing 220 through second fixed plate 22 to for the user provides the damping and feels, promote user's use and experience.

The force applied by the first magnetic body 46 to the hinge 1 is the magnetic repulsive force F1 between the second magnetic body 47 and the first magnetic body 46. It is understood that the damping force received by the damping assembly 40 when rotating is the magnetic repulsive force F1 exerted by the second magnetic body 47 on the first magnetic body 46. In this embodiment, the smaller the distance between the first magnetic body 46 and the first magnetic body 46 is, the larger the magnetic repulsive force F1 exerted by the second magnetic body 47 on the first magnetic body 46 is, the larger the damping force received by the first damping swing arm 41 and the second damping swing arm 42 in the rotation process is, and the more obvious the damping hand feeling provided by the rotation mechanism 100 to the user is.
This embodiment is through setting up first magnetic substance 46 and second magnetic substance 47 at damping piece 2 to provide damping force for first damping swing arm 41 and second damping swing arm 42 through magnetic repulsion F1 between first magnetic substance 46 and the second magnetic substance 47, thereby promote the damping that slewing mechanism 100 provided for the user and feel, experience with the use that promotes the user and feel. In this embodiment, the first magnetic body 46 and the second magnetic body 47 are both permanent magnets, and have a simple structure and a simple processing process, thereby reducing the cost. And, the first magnetic substance 46 and the second magnetic substance 47 that adopt the permanent magnet preparation are magnetic stable, and slewing mechanism 100 is rotating the in-process, and the damping force change that damping subassembly 40 provided is stable to can further promote user's use and experience. Meanwhile, in the present embodiment, the sizes of the first magnetic element 46 and the second magnetic element 47 can be adjusted according to the space in the fixed base 10, so that the space utilization rate of the rotating mechanism 100 can be improved, the size of the rotating mechanism 100 can be reduced, the thickness of the rotating mechanism 100 can be reduced, and the foldable electronic device can be thinned. In addition, the rotating mechanism 100 provided by the embodiment can realize damping hand feeling without arranging an elastic part, and the number of parts of the rotating mechanism 100 is reduced, so that the structure of the rotating mechanism 100 can be simplified, and the assembly difficulty, weight and cost of the rotating mechanism 100 are reduced.

In this embodiment, the first magnetic portion 461 is an N-pole, and the second magnetic portion 462 is an S-pole. The third magnetic portion 471 is an N-pole, and the fourth magnetic portion 472 is an S-pole. In other embodiments, the first magnetic part 461 may be an S-pole and the second magnetic part 462 may be an N-pole.

Referring to fig. 19, fig. 19 is a partial structural schematic view of a rotating mechanism 100 according to a third embodiment of the present application.
The difference from the first and second embodiments is that the damping assembly 40 further includes an elastic member 49. The elastic member 49 is located between the first magnetic body 46 and the second magnetic body 47, and an elastic elongation direction of the elastic member 49 is parallel to the Y direction. In this embodiment, the number of the elastic members 49 is four, and the elastic members 49 are springs. The third fixing rod 483 and the fourth fixing rod 484 extend to the second magnetic body 47 and are fixedly connected to the second magnetic body 47. An elastic member 49 is fitted around the outer circumference of the first fixing bar 481 and is slidable along the corresponding fixing bar 48.
When the first damping swing arm 41 rotates, the first hinge 44 is driven to rotate and abuts against the first hinge seat 464; when the second damping swing arm 42 rotates, the second hinge element 45 is driven to rotate and abuts against the second hinge seat 465, so that the first magnetic element 46 moves towards the direction close to the second magnetic element 47, the magnetic repulsive force F1 between the first magnetic element 46 and the second magnetic element 47 is increased, and the elastic element 49 is compressed, so that the elastic element 49 generates the elastic restoring force F2. The elastic restoring force F2 acts on the first and second hinge members 44 and 45 through the first magnetic member. At this time, the damping force provided by the damping member 2 to the first hinge 44 and the second hinge 45 is a resultant force of the elastic restoring force F2 and the magnetic repulsive force F1, so that the damping force applied to the first damping swing arm 41 and the second damping swing arm 42 can be increased to further improve the damping hand feeling provided by the rotating mechanism 100 to the user, thereby improving the user experience.
The above embodiments and embodiments of the present application are only examples and embodiments, and the scope of the present application is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present application, and all the changes or substitutions should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
