In some embodiments, the first support 210 and the second support 220 can be used to carry devices such as batteries, processors, sensors, etc. and can be electrically connected by wiring structures such as the flexible wiring board 250. However, in the actual manufacturing process, the flexible printed circuit board 250 is often exposed at the position of the rotating shaft assembly 230 due to the mutual rotation relationship between the first bracket 210 and the second bracket 220. Not only the appearance structure between the first bracket 210 and the second bracket 220 is affected, but also the flexible circuit board 250 is easily damaged. Based on this, the embodiment of the present application further designs the mating relationship and related structure between the first bracket 210 and the second bracket 220 to ensure that the flexible circuit board 250 is kept inside the first bracket 210 and the second bracket 220 without being exposed.

The first bracket 210 and the second bracket 220 are in an unfolded state, a closed state and a moving state, and the opening 212 is kept in the second bracket 220. So that the flexible wiring board 250 passing through the opening 212 is not exposed to the outside. When the first bracket 210 and the second bracket 220 are in the unfolded state, as shown in fig. 13, the opening 212 is close to the second sidewall 221 of the second bracket 220, and the opening 212 is blocked by the second sidewall 221. When the first and

second brackets

210 and 220 are in the closed state, as shown in fig. 10, the opening 212 is adjacent to the second outer cover 270, and the opening 212 is blocked by the second outer cover 270. When the first and

second brackets

210 and 220 are in other states, as shown in fig. 11 and 12, the opening 212 is located between the second sidewall 221 and the second cover 270 without being exposed.

The flexible wiring board 250 in the second housing 220 may pass through the through hole 2252. A wireway structure may be provided in the second cradle 220 to place the flexible circuit board 250.

Fig. 18 to 21 show a first perspective view of an elastic element in a rotating mechanism according to an embodiment of the present application, fig. 18 is a second perspective view of the elastic element in the rotating mechanism according to the embodiment of the present application, fig. 20 is an exploded view of the elastic element in the rotating mechanism according to the embodiment of the present application, and fig. 21 is a cross-sectional view of the elastic element in the rotating mechanism according to the embodiment of the present application in one direction. The elastic member 240 may be disposed in one of the first bracket 210 and the second bracket 220, such as the elastic member 240 disposed in the first bracket 210. It is understood that the elastic member 240 provided in the first bracket 210 according to the embodiment of the present invention is only for illustration and does not limit the position where the elastic member 240 is provided, such as the elastic member 240 may be provided in the second bracket 220.

The elastic member 240 may be disposed in the second receiving space 2122 of the first bracket 210 to which the fixing portion 212 is connected and the first receiving space 2113 of the rotating portion 211 is connected. That is, a portion of the elastic member 240 may be disposed in the first receiving space 2113, and another portion of the elastic member 240 may be disposed in the second receiving space 2122. When the first bracket 210, the second bracket 220, the rotation shaft assembly 230, and the elastic assembly 240 are assembled together, the elastic assembly 240 may abut against the stopper 2323 of the rotation shaft assembly 230. When the first bracket 210 rotates around the rotation shaft assembly 230 relative to the second bracket 220, the stopper 2323 does not rotate, and the elastic assembly 240 rotates around the rotation shaft assembly 230 relative to the second bracket 220 along with the first bracket 210. The peripheral outer surface of the stop 2323 gradually changes from the elastic component 240, and because the distance from the outer surface of the cross section of the stop 2323 to the axis of the rotating shaft component 230 is at least partially different, such as changes, the stop 2323 generates different deformation quantities for the elastic component 240 to drive the elastic component 240, so that the elastic component 240 applies an acting force to the first bracket 210, and the first bracket 210 applies an acting force to the rotating shaft component 230 and the second bracket 220, so that the first bracket 210 and the second bracket 220 have an acting force no matter in a rotating state, or in an unfolding state or a closing state, and a certain stability between the first bracket 210 and the second bracket 220 is maintained.

In order to increase the stability of the fit between the stop 2323 and the elastic component 240, and the stop 2323 drives the elastic component 240 to generate different actions, so that the elastic component 240 generates different deformation amounts. The embodiment of the present application may provide the peripheral outer surface of the block 2323 with a configuration having several sides, and may also be understood as at least two side configurations, such as two, three, four, etc. Wherein the shape of at least two sides is different. Such as one of the sides being arcuate with a first arc, one of the sides being arcuate with a second arc, one of the sides being rectangular, etc. The outer peripheral surface of the stopper 2323 according to the embodiment of the present application can be set according to actual requirements.

In some embodiments, the elastic assembly 240 may include an elastic member 242 and a sliding member 243, the elastic member 242 and the sliding member 243 may be fixed in the first bracket 210, such as one end of the elastic member 242 is fixed in the first bracket 210, the other end of the elastic member 242 is engaged with one end of the sliding member 243, and the sliding member 243 may move in the first bracket 210 to drive the elastic member 242 to generate elastic deformation. The other end of the sliding member 243 may abut against the stop 2323, and during the movement of the sliding member 243, the elastic member 242 exerts an elastic force on the sliding member 243, so that the abutting relationship between the sliding member 243 and the stop 2323 may be maintained. The stopper 2323 may drive the sliding member 243 to move, such as slide, so as to deform the elastic member 242.

The elastic member 242 may be an elastic structure such as a spring or a leaf spring that can be deformed. The sliding member 243 may be a structure adapted to the elastic member 242, and the shape of the sliding member 243 may be adapted according to the shape of the elastic member 242.

In order to increase the stability of the elastic member 242 and the sliding member 243 in cooperation with each other and during movement.
