[0035] Reference is made below Figures 1 to 3 A rotating mechanism of the first aspect of the utility model is described in detail.

[0036] Reference Figures 1 to 3 According to the rotating mechanism, the elastic piece group includes a plurality of elastic pieces 200 which are stacked along the axial direction of the rotating shaft 100, each of the elastic pieces 200 includes opposite first elastic parts 210 and second elastic parts 220, the first elastic parts 210 and the second elastic parts 220 are limited to form a penetrating hole 200a, the rotating shaft 100 is detachably arranged in each of the penetrating holes 200a in sequence, and the first elastic parts 210 and the second elastic parts 220 in the same elastic piece 200 are in abutment with the rotating shaft 100; wherein when the rotating shaft 100 rotates forward, the first elastic parts 210 store elastic potential energy under the action of the rotating shaft 100, the second elastic parts 220 release elastic potential energy under the action of the rotating shaft 100, and the elastic force is provided for the forward rotation of the rotating shaft 100; when the rotating shaft 100 rotates reversely, the second elastic parts 220 store elastic potential energy under the action of the rotating shaft 100, and the first elastic parts 210 release elastic potential energy under the action of the rotating shaft 100, so as to provide the elastic force for the reverse rotation of the rotating shaft 100.

[0037] In the rotating mechanism of the embodiment, when the rotating shaft 100 rotates forward under the action of external force, frictional forces are generated between the rotating shaft 100 and the first elastic part 210 and the second elastic part 220, so that the rotating shaft 100 is subjected to certain damping when rotating forward. Meanwhile, in the process of forward rotation of the rotating shaft 100, the first elastic part 210 is away from the second elastic part 220 under the action of frictional force between the rotating shaft 100 and the first elastic part 210, so as to store certain elastic potential energy. The second elastic part 220 has a tendency to approach the first elastic part 210 under the action of frictional force between the rotating shaft 100 and the second elastic part 220, but the second elastic part 220 will not be elastically deformed due to the limiting of the rotating shaft 100. When the rotating shaft 100 stops forward rotation, the first elastic part 210 has a tendency to push the rotating shaft 100 to rotate reversely under the action of its own elasticity, so that the rotating shaft 100 can rotate reversely under the action of smaller external force in the initial stage of reverse rotation. When the rotating shaft 100 rotates reversely under the action of external force, frictional forces are generated between the rotating shaft 100 and the first elastic part 210 and the second elastic part 220, so that the rotating shaft 100 is subjected to certain damping when rotating reversely. Meanwhile, in the process of reverse rotation of the rotating shaft 100, the second elastic part 220 is away from the first elastic part 210 under the action of frictional force between the rotating shaft 100 and the second elastic part 220, so as to store certain elastic potential energy. The first elastic part 210 has a tendency to approach the second elastic part 220 under the action of frictional force between the rotating shaft 100 and the first elastic part 210, but the first elastic part 210 will not be elastically deformed due to the limiting of the rotating shaft 100. When the rotating shaft 100 stops reverse rotation, the second elastic part 220 has a tendency to push the rotating shaft 100 to rotate forwardly under the action of its own elasticity, so that the rotating shaft 100 can rotate forwardly under the action of smaller external force in the initial stage of forward rotation.

[0038] It can be understood that each elastic part 200 in the elastic part group can provide certain damping when the rotating shaft 100 rotates, so that the worker can increase or decrease the number of elastic parts 200 in the elastic part group to increase or decrease the damping suffered by the rotating shaft 100 when rotating. Meanwhile, since the damping provided by each elastic part 200 is certain, the worker can more accurately adjust the damping suffered by the rotating shaft 100 when rotating by increasing or decreasing the number of elastic parts 200, and the rotating structure of the application is more convenient to adjust the size of the torque.

[0039] It can be understood that since the elastic part group is composed of elastic parts 200 of the same specification, each elastic part 200 in the elastic part group can be integrally formed by using a mold of the same specification, so that the manufacturing process of the elastic part group is simpler and the manufacturing cost is lower.

[0040] Reference Figure 2 In some embodiments of the present application, the elastic member 200 further comprises a mounting portion 230, the first elastic portion 210 comprises a first abutting section 211 and a first connecting section 212 connected with each other, the second elastic portion 220 comprises a second abutting section 221 and a second connecting section 222 connected with each other, the first connecting section 212 and the second connecting section 222 are connected with the mounting portion 230, and the first connecting section 212 and the second connecting section 222 are both spaced apart from the rotating shaft 100, and the first abutting section 211 and the second abutting section 221 are both arranged in close contact with the rotating shaft 100.

[0041] It can be understood that, by setting the first elastic portion 210 into two sections, and arranging the first abutting section 211 in close contact with the rotating shaft 100, and arranging the first connecting section 212 to be spaced apart from the rotating shaft 100, and setting the second elastic portion 220 into two sections, and arranging the second abutting section 221 in close contact with the rotating shaft 100, and arranging the second connecting section 222 to be spaced apart from the rotating shaft 100, when the rotating shaft 100 rotates relative to the elastic member set, the rotating shaft 100 only generates frictional force with the first abutting section 211 in the first elastic portion 210 and the second abutting section 221 in the second elastic portion 220, so that the contact area between the rotating shaft 100 and the elastic member set is relatively small, so that the frictional force acting on the rotating shaft 100 during rotation is relatively small, so that the external force required to drive the rotating shaft 100 to rotate is relatively small, so as to ensure smooth rotation of the rotating shaft 100.

[0042] As Figure 1 and Figure 3 shown, in some embodiments of the present application, the rotating mechanism further comprises a first connecting member 300, and the mounting portion 230 of each elastic member 200 is detachably connected with the first connecting member 300. It can be understood that, by detachably connecting the mounting portion 230 of each elastic member 200 with the first connecting member 300, when it is necessary to adjust the number of elastic members 200, it is only necessary to mount the elastic member 200 on the first connecting member 300, or to detach part of the elastic members 200 in the elastic member set from the first connecting member 300.

[0043] As Figure 2As shown in some embodiments, the first connecting piece 300 is provided with a clamping groove 310, the extending direction of the clamping groove 310 is parallel to the axial direction of the rotating shaft 100, and the mounting portion 230 is at least partially slidably arranged in the clamping groove 310. It can be understood that by sliding the mounting portion 230 of the elastic member 200 into the clamping groove 310 of the first connecting piece 300, the mounting of the elastic member 200 on the first connecting piece 300 is realized, so as to increase the number of elastic members 200 in the elastic member group; by sliding the elastic member 200 in the elastic member group out of the clamping groove 310 to separate from the first connecting piece 300, the dismounting of the elastic member 200 on the first connecting piece 300 is realized, so as to reduce the number of elastic members 200 in the elastic member group.

[0044] As shown in some embodiments, Figure 2 and Figure 3 As shown in some embodiments, the first connecting piece 300 is provided with a counterbore groove 320, the extending direction of the counterbore groove 320 is parallel to the axial direction of the rotating shaft 100, and the clamping groove 310 is arranged at the groove bottom of the counterbore groove 320, and the groove side wall of the counterbore groove 320 leaves a clearance with the elastic member 200. It can be understood that in the rotating process of the rotating shaft 100, the first elastic portion 210 and / or the second elastic portion 220 will be deformed, and due to the clearance between the first elastic portion 210 and the second elastic portion 220 and the groove side wall of the counterbore groove 320, the first elastic portion 210 and / or the second elastic portion 220 have sufficient deformation space when they are elastically deformed.

[0045] As shown in some embodiments, Figure 3 As shown in some embodiments, the rotating mechanism further comprises a second connecting piece 400, the second connecting piece 400 is provided with a waist-shaped hole 410, and the rotating shaft 100 is clamped in the waist-shaped hole 410. It can be understood that by clamping the rotating shaft 100 with the waist-shaped hole 410 of the second connecting piece 400, when the second connecting piece 400 rotates, the rotating shaft 100 can rotate with the second connecting piece 400, and when it is necessary to separate the second connecting piece 400 from the rotating shaft 100, it is only necessary to move the second connecting piece 400 along the rotating shaft 100 to make the rotating shaft 100 separate from the waist-shaped hole 410, the connection form between the second connecting piece 400 and the rotating shaft 100 is simple, and the dismounting of the second connecting piece 400 on the rotating shaft 100 is more convenient.

[0046] As shown in some embodiments, Figure 1 and Figure 3In some embodiments of the utility model, the shaft shoulder 110 is arranged on the rotating shaft 100, the rotating mechanism further comprises a gasket 500, the gasket 500 is installed on the rotating shaft 100 and located on the side of the elastic piece group away from the shaft shoulder 110, and the gasket 500 is used for limiting the elastic piece group in the axial direction of the rotating shaft 100 in cooperation with the shaft shoulder 110. It can be understood that by arranging the gasket 500 and the shaft shoulder 110 on the opposite sides of the elastic piece group in the axial direction of the rotating shaft 100 respectively, the positions of each elastic piece 200 in the elastic piece group in the axial direction of the rotating shaft 100 can be limited, so as to prevent the elastic piece 200 from being separated from the rotating shaft 100.

[0047] The utility model is described in detail below Figures 1 to 4 The electronic device of the second aspect of the utility model is described in detail.

[0048] Reference Figure 4 According to the electronic device of the second aspect of the utility model, the rotating mechanism of the first aspect of the utility model is included, and the electronic device further comprises a bottom plate 600 and a folding plate 700, the bottom plate 600 is connected with the first connecting piece 300, and the folding plate 700 is connected with the second connecting piece 400. It can be understood that in the process of opening the electronic device, the folding plate 700 rotates forward relative to the bottom plate 600 to move away from the bottom plate 600, at this time, the second connecting piece 400 drives the rotating shaft 100 to rotate forward, so that the first elastic part 210 stores a part of elastic potential energy under the action of the rotating shaft 100, and the second elastic part 220 releases the stored elastic potential energy, so that the user only needs to exert a small force in the initial stage of opening the electronic device, when the user needs to close the electronic device, the folding plate 700 rotates reversely relative to the bottom plate 600 to move close to the bottom plate 600, the second connecting piece 400 drives the rotating shaft 100 to rotate reversely, the second elastic part 220 stores a part of elastic potential energy under the action of the rotating shaft 100, and the first elastic part 210 releases the stored elastic potential energy, so that the user only needs to exert a small force in the initial stage of closing the electronic device.

[0049] As Figure 4 shown, in some embodiments of the utility model, two rotating mechanisms are arranged, and the two rotating mechanisms are symmetrically distributed along the axial direction of the rotating shaft 100. It can be understood that by symmetrically distributing the two rotating mechanisms along the axial direction of the rotating shaft 100, the second connecting piece 400 in the two rotating mechanisms can be prevented from separating from the corresponding rotating shaft 100.

[0050] As Figure 1 and Figure 3As shown, in some embodiments of the utility model, the first connecting piece 300 is provided with lugs 330, and the lugs 330 are detachably connected with the bottom plate 600 through threaded connectors. It can be understood that by providing the lugs 330 on the first connecting piece 300, the user can connect the lugs 330 with the bottom plate 600 by screwing the threaded connectors.
