Usually, a rotating mechanism is provided in the electronic device, and the two ends of the rotating mechanism are respectively connected to the first shell and the second shell of the electronic device, so that the first shell and the second shell can be close to each other or away from each other, so that the electronic device can switch between a folded state and an unfolded state.

[0003] In the related art, the rotating mechanism includes a rotating shaft assembly, to which a relatively complex gear structure is connected. The transmission of the gear structure requires a certain amount of time, which leads to the problem that the two ends of the rotating mechanism cannot move synchronously when the rotating mechanism switches between the folded state and the unfolded state. Summary of the invention

[0004] The embodiments of the present application provide a rotating mechanism and an electronic device to solve the problem in the related art that the two ends of the rotating mechanism cannot move synchronously when the rotating mechanism switches between a folded state and an unfolded state.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, an embodiment of the present application provides a rotation mechanism, the rotation mechanism comprising: a rotation assembly, a rotating shaft assembly, and a transmission fluid cylinder assembly;

[0007] The shaft assembly comprises a first shaft and a second shaft, the first shaft and the second shaft are spaced apart, the first shaft and the second shaft are both fixedly connected to the rotating assembly, the first end of the transmission fluid cylinder assembly is sleeved on the first shaft, the second end of the transmission fluid cylinder assembly is sleeved on the second shaft, and the transmission fluid is stored in the transmission fluid cylinder assembly;

[0008] The rotating assembly has an unfolded state and a folded state. When the rotating assembly drives the first rotating shaft to rotate, the first rotating shaft drives the transmission fluid to flow in the transmission fluid cylinder assembly to make the second rotating shaft rotate synchronously, so that the rotating assembly switches between the unfolded state and the folded state.

[0009] In a second aspect, an embodiment of the present application provides an electronic device, wherein the electronic device includes the rotating mechanism described in the first aspect.

[0010] In the embodiment of the present application, since the first rotating shaft and the second rotating shaft are arranged at intervals, and the first rotating shaft and the second rotating shaft are both fixedly connected to the rotating shaft assembly, the rotating assembly can drive the first rotating shaft and / or the second rotating shaft to rotate. Since the first end of the transmission fluid cylinder assembly is sleeved on the first rotating shaft, the second end of the transmission fluid cylinder assembly is sleeved on the second rotating shaft, and the transmission fluid is stored in the transmission fluid cylinder assembly, when the rotating assembly drives the first rotating shaft to rotate, the first rotating shaft can drive the transmission fluid to flow in the transmission fluid cylinder assembly, and the transmission fluid is incompressible, so that the second rotating shaft is synchronously rotated through the transmission fluid, so that the rotating assembly switches between the unfolded state and the folded state. That is, in the embodiment of the present application, the transmission fluid cylinder assembly is sleeved on the first rotating shaft and the second rotating shaft, so that when the rotating assembly drives the first rotating shaft to rotate, the first rotating shaft causes the transmission fluid in the transmission fluid cylinder assembly to flow, so that the second rotating shaft synchronizes with the rotating shaft, so that the rotating assembly can switch between the expanded state and the folded state, thereby avoiding the problem that a more complex gear structure is connected to the rotating shaft assembly, so that the two ends of the rotating assembly cannot move synchronously when the rotating assembly switches between the folded state and the expanded state.

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present application. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0019] Reference Figure 1 , showing a schematic diagram of a rotating assembly provided in an embodiment of the present application in an unfolded state; referring to Figure 2 , showing a schematic diagram of a rotating assembly provided in an embodiment of the present application in a folded state; referring to Figure 3 , showing a schematic diagram of a first inner wall provided in an embodiment of the present application being sleeved on a first rotating shaft; referring to Figure 4 , shows a schematic diagram of a second inner wall provided in an embodiment of the present application being sleeved on a second rotating shaft. Figures 1 to 4 As shown, the rotating mechanism includes: a rotating assembly 10, a rotating shaft assembly 20 and a transmission fluid cylinder assembly 30.

[0020] The shaft assembly 20 includes a first shaft 21 and a second shaft 22, the first shaft 21 and the second shaft 22 are spaced apart, the first shaft 21 and the second shaft 22 are both fixedly connected to the rotating assembly 10, the first end of the transmission fluid cylinder assembly 30 is sleeved on the first shaft 21, the second end of the transmission fluid cylinder assembly 30 is sleeved on the second shaft 22, and transmission fluid is stored in the transmission fluid cylinder assembly 30. The rotating assembly 10 has an unfolded state and a folded state. When the rotating assembly 10 drives the first shaft 21 to rotate, the first shaft 21 drives the transmission fluid to flow in the transmission fluid cylinder assembly 30, so that the second shaft 22 rotates synchronously, so that the rotating assembly 10 switches between the unfolded state and the folded state.

[0021] In the embodiment of the present application, since the first rotating shaft 21 and the second rotating shaft 22 are arranged at intervals, and the first rotating shaft 21 and the second rotating shaft 22 are both fixedly connected to the rotating shaft assembly 20, the rotating assembly 10 can drive the first rotating shaft 21 and / or the second rotating shaft 22 to rotate. Since the first end of the transmission fluid cylinder assembly 30 is sleeved on the first rotating shaft 21, the second end of the transmission fluid cylinder assembly 30 is sleeved on the second rotating shaft 22, and the transmission fluid is stored in the transmission fluid cylinder assembly 30, when the rotating assembly 10 drives the first rotating shaft 21 to rotate, the first rotating shaft 21 can drive the transmission fluid to flow in the transmission fluid cylinder assembly 30, and the transmission fluid is incompressible, so that the second rotating shaft 22 is synchronously rotated through the transmission fluid, so that the rotating assembly 10 switches between the unfolded state and the folded state. That is, in the embodiment of the present application, the transmission fluid cylinder assembly 30 is sleeved on the first rotating shaft 21 and the second rotating shaft 22, so that when the rotating assembly 10 drives the first rotating shaft 21 to rotate, the first rotating shaft 21 causes the transmission fluid in the transmission fluid cylinder assembly 30 to flow, so that the second rotating shaft 22 rotates synchronously, so that the rotating assembly 10 switches between the unfolded state and the folded state, thereby avoiding the problem that a more complex gear structure is connected to the rotating shaft assembly 20, so that the rotating assembly 10 switches between the folded state and the unfolded state, and the two ends of the rotating assembly 10 cannot move synchronously.

[0022] It should be noted that, in the embodiment of the present application, the transmission fluid can be selected according to actual needs, for example, the transmission fluid can be water, oil, or other flowable liquids. In addition, when the types of transmission fluids are different, the viscosities of the transmission fluids are also different, that is, transmission fluids of different viscosities can be stored in the transmission fluid cylinder assembly 30.

[0023] In addition, in the embodiment of the present application, by providing the transmission fluid cylinder assembly 30, the transmission fluid is stored in the transmission fluid cylinder assembly 30. When the first rotating shaft 21 drives the transmission fluid to flow in the transmission fluid cylinder assembly 30, the second rotating shaft 22 rotates synchronously under the action of the transmission fluid, which is equivalent to transmission through the transmission fluid, thereby avoiding the use of a more complex recording mechanism such as gears, thereby avoiding the noise generated by structures such as gears. That is, by using the transmission fluid cylinder assembly 30, the noise of the rotating structure can also be reduced.

[0024] In addition, in some embodiments, the transmission fluid cylinder assembly 30 may include a first cylinder body 31 and a second cylinder body 32. The first cylinder body 31 includes a first inner wall 311 and a first outer wall 312, the first inner wall 311 and the first outer wall 312 are enclosed to form a first accommodating chamber, and the first inner wall 311 and the first outer wall 312 are rotatable, and the first accommodating chamber contains transmission fluid. The second cylinder body 32 includes a second inner wall 321 and a second outer wall 322, the second inner wall 321 and the second outer wall 322 are enclosed to form a second accommodating chamber, and the second inner wall 321 and the second outer wall 322 are rotatable, and the second accommodating chamber contains transmission fluid. The first accommodating chamber is connected to the second accommodating chamber, the first inner wall 311 is penetrated by the first rotating shaft 21, and the second inner wall 321 is penetrated by the second rotating shaft 22.

[0025] Since the first inner wall 311 and the first outer wall 312 are enclosed to form a first accommodation cavity, the first inner wall 311 and the first outer wall 312 are rotatable, and the first inner wall 311 is provided through the first rotating shaft 21, therefore, when the first rotating shaft 21 rotates, the first rotating shaft 21 can drive the first inner wall 311 to rotate. Since the second inner wall 321 and the second outer wall 322 are enclosed to form a second accommodation cavity, the second inner wall 321 and the second outer wall 322 are rotatable, and the second inner wall 321 is provided through the second rotating shaft 22, therefore, when the second rotating shaft 22 rotates, the second rotating shaft 22 can drive the second inner wall 321 to rotate. Since the first accommodating chamber and the second accommodating chamber both contain transmission fluid, and the first accommodating chamber is connected to the second accommodating chamber, when the first rotating shaft 21 is turned, the first rotating shaft 21 can drive the first inner wall 311 to rotate, so that the transmission fluid in the first accommodating chamber flows into the second accommodating chamber. After the transmission fluid flows to the second accommodating chamber, the transmission fluid can drive the second inner wall 321 to rotate, so that the second rotating shaft 22 rotates synchronously, so that the rotating component 10 switches between the unfolded state and the folded state.

[0026] It should be noted that the first cylinder body 31 may be a first end of the transmission fluid cylinder assembly 30 , and the second cylinder body 32 may be a second end of the transmission fluid cylinder assembly 30 .

[0027] In addition, in some embodiments, a first movable plate 3112 may be provided on the first inner wall 311, the first movable plate 3112 is located in the first accommodation chamber, a first end of the first movable plate 3112 is fixedly connected to the first inner wall 311, a second end of the first movable plate 3112 is sealedly connected to the first outer wall 312, and the first movable plate 3112 is rotatable relative to the first outer wall 312. A first fixed plate 3121 may be provided on the first outer wall 312, the first fixed plate 3121 is located in the first accommodation chamber, a first end of the first fixed plate 3121 is fixedly connected to the first outer wall 312, a second end of the first fixed plate 3121 is sealedly connected to the first inner wall 311, and the first inner wall 311 is rotatable relative to the first fixed plate 3121, the first movable plate 3112 and the first fixed plate 3121 divide the first accommodation chamber into two first sub-accommodation chambers, and the transmission fluid is located in one of the first sub-accommodation chambers. A second movable plate 3212 may be provided on the second inner wall 321, the second movable plate 3212 is located in the second accommodation chamber, the first end of the second movable plate 3212 is fixedly connected to the second inner wall 321, the second end of the second movable plate 3212 is sealedly connected to the second outer wall 322, and the second movable plate 3212 is rotatable relative to the second outer wall 322. A second fixed plate 3221 may be provided on the second outer wall 322, the second fixed plate 3221 is located in the second accommodation chamber, the first end of the second fixed plate 3221 is fixedly connected to the second outer wall 322, the second end of the second fixed plate 3221 is sealedly connected to the second inner wall 321, and the second inner wall 321 is rotatable relative to the second fixed plate 3221. The second movable plate 3212 and the second fixed plate 3221 divide the second accommodation chamber into two second sub-accommodation chambers, and the transmission fluid is located in one of the second sub-accommodation chambers. The first sub-accommodation chamber containing the transmission fluid is connected to the second sub-accommodation chamber containing the transmission fluid.

[0028] Since the first end of the first movable plate 3112 is fixedly connected to the first inner wall 311, the second end of the first movable plate 3112 is sealedly connected to the first outer wall 312, the first movable plate 3112 is rotatable relative to the first outer wall 312, the first end of the first fixed plate 3121 is fixedly connected to the first outer wall 312, and the second end of the first fixed plate 3121 is sealedly connected to the first inner wall 311, therefore, when the first inner wall 311 rotates, the first inner wall 311 can drive the first movable plate 3112 to rotate, so that the space between the first movable plate 3112 and the first fixed plate 3121 changes, or when the first movable plate 3112 is rotated under force, the first movable plate 3112 drives the first inner wall 311 to rotate, and the space between the first movable plate 3112 and the first fixed plate 3121 changes. In addition, the first movable plate 3112 and the first fixed plate 3121 divide the first accommodating chamber into two first sub-accommodating chambers, and there is transmission fluid in one first sub-accommodating chamber, so that when the first movable plate 3112 rotates relative to the first fixed plate 3212, the first movable plate 3112 will apply force to the transmission fluid to make the transmission fluid flow, that is, make the transmission fluid flow into the second accommodating chamber.

[0029] Since the first end of the second movable plate 3212 is fixedly connected to the second inner wall 321, the second end of the second movable plate 3212 is sealedly connected to the second outer wall 322, the second movable plate 3212 is rotatable relative to the second outer wall 322, the first end of the second fixed plate 3221 is fixedly connected to the second outer wall 322, and the second end of the second fixed plate 3221 is sealedly connected to the second inner wall 321, therefore, when the second inner wall 321 rotates, the second inner wall 321 can drive the second movable plate 3212 to rotate, so that the space between the second movable plate 3212 and the second fixed plate 3221 changes, or when the second movable plate 3212 is rotated under force, the second movable plate 3212 drives the second inner wall 321 to rotate, and the space between the second movable plate 3212 and the second fixed plate 3221 changes. In addition, the second movable plate 3212 and the second fixed plate 3221 divide the second accommodating chamber into two second sub-accommodating chambers, and there is transmission fluid in one second sub-accommodating chamber, so that when the second movable plate 3212 rotates relative to the second fixed plate 3221, the second movable plate 3212 will apply force to the transmission fluid to make the transmission fluid flow, that is, make the transmission fluid flow into the first accommodating chamber.

[0030] When the first rotating shaft 21 rotates, the first rotating shaft 21 drives the first inner wall 311 to rotate, and the first inner wall 311 drives the first movable plate 3112 to rotate relative to the first outer wall 312, so that the first movable plate 3112 can apply force to the transmission fluid in a first sub-accommodating chamber, so that the transmission fluid flows out of the first sub-accommodating chamber and flows into the second sub-accommodating chamber with the transmission fluid. The transmission fluid flowing into the second sub-accommodating chamber with the transmission fluid will apply force to the second movable plate 3212, so that the second movable plate 3212 rotates, so that the second movable plate 3212 drives the second inner wall 321 to rotate, so that the second inner wall 321 drives the second rotating shaft 22 to rotate. It is equivalent to that the first rotating shaft 21 and the second rotating shaft 22 can rotate synchronously.

[0031] Similarly, when the second rotating shaft 22 rotates, the second rotating shaft 22 drives the second inner wall 321 to rotate, and the second inner wall 321 drives the second movable plate 3212 to rotate relative to the second outer wall 322, so that the second movable plate 3212 can apply force to the transmission fluid in a second sub-accommodating chamber, so that the transmission fluid flows out of the second sub-accommodating chamber and flows into the first sub-accommodating chamber with the transmission fluid. The transmission fluid flowing into the first sub-accommodating chamber with the transmission fluid will apply force to the first movable plate 3112, so that the first movable plate 3112 rotates, so that the first movable plate 3112 drives the first inner wall 311 to rotate, so that the first inner wall 311 drives the first rotating shaft 21 to rotate. It is equivalent to that the first rotating shaft 21 and the second rotating shaft 22 can rotate synchronously.

[0032] In addition, by making the first end of the first fixed plate 3121 fixedly connected to the first outer wall 312, the second end of the first fixed plate 3121 sealedly connected to the first inner wall 311, the first end of the first movable plate 3112 fixedly connected to the first inner wall 311, and the second end of the first movable plate 3112 sealedly connected to the first outer wall 312, it is possible to prevent the transmission fluid from leaking into another first sub-accommodating chamber when the transmission fluid flows in one first sub-accommodating chamber. Similarly, by making the first end of the second fixed plate 3221 fixedly connected to the second outer wall 322, the second end of the second fixed plate 3221 sealedly connected to the second inner wall 321, the first end of the second movable plate 3212 fixedly connected to the second inner wall 321, and the second end of the second movable plate 3212 sealedly connected to the second outer wall 322, it is possible to prevent the transmission fluid from leaking into another second sub-accommodating chamber when the transmission fluid flows in one second sub-accommodating chamber.

[0033] In addition, in some embodiments, the second end of the first movable plate 3112 may be provided with a first seal, the first seal is fixedly connected to the second end of the first movable plate 3112, and the first seal contacts the first outer wall 312. The second end of the first fixed plate 3121 may be provided with a second seal, the second seal is fixedly connected to the second end of the first fixed plate 3121, and the second seal contacts the first inner wall 311. The second end of the second movable plate 3212 may be provided with a third seal, the third seal is fixedly connected to the second end of the second movable plate 3212, and the third seal contacts the second outer wall 322. The second end of the second fixed plate 3221 may be provided with a fourth seal, the fourth seal is fixedly connected to the second end of the second fixed plate 3221, and the fourth seal contacts the second inner wall 321.

[0034] When the second end of the first movable plate 3112 is provided with a first seal, the first seal is fixedly connected to the second end of the first movable plate 3112, and the first seal contacts the first outer wall 312, at this time, when the first movable plate 3112 is rotated under force, the first movable plate 3112 drives the first seal to move, and the first seal is always in contact with the first outer wall 312, so that the first seal always makes the second end of the first movable plate 3112 sealed and connected to the first outer wall 312. Similarly, the second end of the first fixed plate 3121 can be provided with a second seal, the second seal is fixedly connected to the second end of the first fixed plate 3121, and the second seal contacts the first inner wall 311, so that when the first inner wall 311 rotates, the second seal is always in contact with the first inner wall 311, so that the second seal always makes the second end of the first fixed plate 3121 sealed and connected to the first inner wall 311. Thus, by providing the first seal and the second seal, the first movable plate 3112 and the second movable plate 3212 divide the first receiving chamber into two independent first sub-receiving chambers, and the transmission fluid in the first sub-receiving chamber containing the transmission fluid will not flow into the other first sub-receiving chamber.

[0035] In addition, when the second end of the second movable plate 3212 is provided with a third seal, the third seal is fixedly connected to the second end of the second movable plate 3212, and the third seal is in contact with the second outer wall 322, at this time, when the second movable plate 3212 is rotated by force, the second movable plate 3212 drives the third seal to move, and the third seal is always in contact with the second outer wall 322, so that the third seal always makes the second end of the second movable plate 3212 sealed and connected with the second outer wall 322. Similarly, the second end of the second fixed plate 3221 can be provided with a fourth seal, the fourth seal is fixedly connected to the second end of the second fixed plate 3221, and the fourth seal is in contact with the second inner wall 321, so that when the second inner wall 321 rotates, the fourth seal is always in contact with the second inner wall 321, so that the fourth seal always makes the second end of the second fixed plate 3221 sealed and connected with the second inner wall 321. Therefore, by providing the third seal and the fourth seal, the second movable plate 3212 and the second movable plate 3212 divide the second receiving chamber into two independent second sub-receiving chambers, and the transmission fluid in the second sub-receiving chamber containing the transmission fluid will not flow into another second sub-receiving chamber.

[0036] It should be noted that the first seal, the second seal, the third seal and the fourth seal can all be silicone. Of course, they can also be other components, such as rubber. This embodiment of the present application does not limit this.

[0037] In addition, in some embodiments, the rotating assembly 10 may further include a conducting tube 40. A first conducting hole is provided on the first outer wall 312, a second conducting hole is provided on the second outer wall 322, one end of the conducting tube 40 is sealedly connected to the first conducting hole, and the other end of the conducting tube 40 is sealedly connected to the second conducting hole.

[0038] Since one end of the conducting tube 40 is sealed and connected to the first conducting hole on the first outer wall 312, and the other end of the conducting tube 40 is sealed and connected to the second conducting hole on the second outer wall 322, it is equivalent to that the first accommodating chamber and the second accommodating chamber are connected through the conducting tube 40, so that the transmission fluid in the first accommodating chamber can flow out from the first accommodating chamber, flow into the conducting tube 40, and then flow to the second accommodating chamber through the conducting tube 40, or the transmission fluid in the second accommodating chamber can flow out from the second accommodating chamber, flow into the conducting tube 40, and then flow to the first accommodating chamber through the conducting tube 40. That is, by providing the conducting tube 40, the conducting tube 40 can make the transmission fluid in the first accommodating chamber flow to the second accommodating chamber, or make the transmission fluid in the second accommodating chamber flow to the first accommodating chamber, so as to facilitate the flow of the transmission fluid in the first accommodating chamber and the second accommodating chamber, and facilitate the connection between the first accommodating chamber and the second accommodating chamber.

[0039] It should be noted that the sealing connection between one end of the conducting tube 40 and the first conducting hole can be: one end of the conducting tube 40 can be welded at the first conducting hole, so that the one end of the conducting tube 40 is sealed and connected to the first conducting hole. Of course, the sealing connection between one end of the conducting tube 40 and the first conducting hole can also be other ways. For example, one end of the conducting tube 40 is embedded in the first conducting hole, and a sealing ring is provided between the conducting tube 40 and the hole wall of the first conducting hole.

[0040] In addition, the manner in which the other end of the conducting tube 40 is sealed and connected to the second conducting hole can be referred to the manner in which one end of the conducting tube 40 is sealed and connected to the first conducting hole, and will not be described in detail here.

[0041] In addition, in some embodiments, the rotating assembly 10 may include a first rotating plate 11 and a second rotating plate 12. The first rotating plate 11 is fixedly connected to the first rotating shaft 21, and the second rotating plate 12 is fixedly connected to the second rotating shaft 22.

[0042] Since the first rotating plate 11 is fixedly connected to the first rotating shaft 21, when the first rotating plate 11 rotates, the first rotating plate 11 drives the first rotating shaft 21 to rotate. Since the first inner wall 311 is provided through the first rotating shaft 21, when the first rotating shaft 21 rotates, the first rotating shaft 21 can drive the first inner wall 311 to rotate relative to the first outer wall 312, so that the transmission fluid in the first accommodating chamber can flow. In addition, since the second rotating plate 12 is fixedly connected to the second rotating shaft 22, when the second rotating plate 12 rotates, the second rotating plate 12 drives the second rotating shaft 22 to rotate. Since the second inner wall 321 is provided through the second rotating shaft 22, when the second rotating shaft 22 rotates, the second rotating shaft 22 can drive the second inner wall 321 to rotate relative to the second outer wall 322, so that the transmission fluid in the second accommodating chamber can flow. Since the first accommodating chamber is connected to the second accommodating chamber, when the first rotating shaft 21 rotates, the transmission fluid in the first accommodating chamber can flow into the second accommodating chamber, and when the second rotating shaft 22 rotates, the transmission fluid in the second accommodating chamber can flow into the first accommodating chamber, so that the transmission fluid in the first accommodating chamber and the second accommodating chamber can flow. In addition, since the liquid is incompressible, that is, the transmission fluid is incompressible, after the first rotating shaft 21 rotates, the transmission fluid in the first accommodating chamber at least partially flows out of the first accommodating chamber and flows into the second accommodating chamber, so that the volume of the transmission fluid flowing out of the first accommodating chamber is equal to the volume of the transmission fluid flowing into the second accommodating chamber, and the transmission fluid flowing into the second accommodating chamber causes the second inner wall 321 to rotate, so that the second inner wall 321 drives the second rotating shaft 22 to rotate, so that the second rotating shaft 22 drives the second rotating plate 12 to rotate, so that the first rotating plate 11 and the second rotating plate 12 rotate at the same time, and the first rotating plate 11 and the second rotating plate 12 are close to each other or away from each other, so that the rotating assembly 10 switches between the unfolded state and the folded state.

[0043] Similarly, after the second rotating shaft 22 rotates, at least part of the transmission fluid in the second accommodating chamber flows out of the second accommodating chamber and flows into the first accommodating chamber, so that the volume of the transmission fluid flowing out of the second accommodating chamber is equal to the volume of the transmission fluid flowing into the first accommodating chamber, and the transmission fluid flowing into the first accommodating chamber causes the first inner wall 311 to rotate, so that the first inner wall 311 drives the first rotating shaft 21 to rotate, so that the first rotating shaft 21 drives the first rotating plate 11 to rotate, so that the first rotating plate 11 and the second rotating plate 12 rotate at the same time, and the first rotating plate 11 and the second rotating plate 12 approach each other or move away from each other, so that the rotating assembly 10 switches between the unfolded state and the folded state.

[0044] The above description is directed to the process of the rotating assembly 10 switching between the unfolded state and the folded state when the first rotating plate 11 is rotated by an external force, or the second rotating plate 12 is rotated by an external force. Of course, the first rotating plate 11 and the second rotating plate 12 can be rotated by an external force at the same time. At this time, the transmission fluid in the first accommodating chamber and the transmission fluid in the second accommodating chamber can flow into the conducting tube 40, so that the first rotating plate 11 and the second rotating plate 12 can move closer to each other or farther away from each other, that is, the rotating assembly 10 switches between the unfolded state and the folded state.

[0045] It should be noted that when the first rotating plate 11 is fixedly connected to the first rotating shaft 21, and the second rotating plate 12 is fixedly connected to the second rotating shaft 22, at this time, the first rotating shaft 21 can be rotated by applying force to the first rotating plate 11, so that the second rotating shaft 22 is rotated by the action of the transmission fluid, and finally the second rotating plate 12 is rotated, so that the first rotating plate 11 and the second rotating plate 12 are moved closer to each other or farther away from each other. Similarly, force can also be applied to the second rotating plate 12 to rotate the second rotating shaft 22, so that the first rotating shaft 21 is rotated by the action of the transmission fluid, and finally the first rotating plate 11 is rotated, so that the first rotating plate 11 and the second rotating plate 12 are moved closer to each other or farther away from each other.

[0046] In addition, in the embodiment of the present application, after the first inner wall 311 is penetrated by the first rotating shaft 21 and the second inner wall 321 is penetrated by the second rotating shaft 22, different structures can be set on the first inner wall 311 and the first rotating shaft 21, so that the first rotating shaft 21 drives the first inner wall 311 to rotate, or the first inner wall 311 drives the first rotating shaft 21 to rotate. Similarly, different structures can also be set on the second inner wall 321 and the second rotating shaft 22, so that the second rotating shaft 22 drives the second inner wall 321 to rotate, or the second inner wall 321 drives the second rotating shaft 22 to rotate. The following examples are used for specific description:

[0047] Method (1): The first inner wall 311 may be provided with a first slot 3111, the first shaft 21 may be provided with a first boss 211, and the first boss 211 is engaged in the first slot 3111. The second inner wall 321 may be provided with a second slot 3211, the second shaft 22 may be provided with a second boss 221, and the second boss 221 is engaged in the second slot 3211.

[0048] When the first boss 211 is engaged in the first slot 3111, when the first shaft 21 is rotated under force, the first boss 211 applies force to the slot wall of the first slot 3111, so that the slot wall of the first slot 3111 moves, that is, the first inner wall 311 rotates with the rotation of the first shaft 21. When the first inner wall 311 is rotated under force, when the first slot 3111 is rotated under force, the slot wall of the first slot 3111 applies force to the first boss 211, so that the first boss 211 moves, that is, the first shaft 21 rotates with the rotation of the first inner wall 311.

[0049] Similarly, when the second boss 221 is engaged in the second slot 3211, when the second shaft 22 is rotated under force, the second shaft 22 will apply force to the slot wall of the second slot 3211, so that the slot wall of the second slot 3211 moves, that is, the second inner wall 321 rotates with the rotation of the second shaft 22. When the second inner wall 321 is rotated under force, at this time, the slot wall of the second slot 3211 will apply force to the second boss 221, so that the second boss 221 moves, that is, the second shaft 22 rotates with the rotation of the second inner wall 321.

[0050] That is, by providing the first slot 3111 on the first inner wall 311, providing the first boss 211 on the first rotating shaft 21, and the first boss 211 being engaged in the first slot 3111, the first inner wall 311 can drive the first rotating shaft 21 to rotate, or the first rotating shaft 21 can drive the first inner wall 311 to rotate. Similarly, by providing the second slot 3211 on the second inner wall 321, providing the second boss 221 on the second rotating shaft 22, and the second boss 221 being engaged in the second slot 3211, the second inner wall 321 can drive the second rotating shaft 22 to rotate, or the second rotating shaft 22 can drive the second inner wall 321 to rotate.

[0051] Method (2): A third boss may be provided on the first inner wall 311, a third slot may be provided on the first rotating shaft 21, and the third boss is engaged in the third slot. A fourth boss may be provided on the second inner wall 321, a fourth slot may be provided on the second rotating shaft 22, and the fourth boss is engaged in the fourth slot.

[0052] When the third boss is engaged in the third slot, at this time, when the first rotating shaft 21 is rotated under force, the slot wall of the third slot will apply force to the third boss, so that the third boss moves, that is, the first inner wall 311 rotates with the rotation of the first rotating shaft 21. When the first inner wall 311 is rotated under force, at this time, the third boss will apply force to the slot wall of the third slot, so that the slot wall of the third slot moves, that is, the first rotating shaft 21 rotates with the rotation of the first inner wall 311.

[0053] Similarly, when the fourth boss is engaged in the fourth slot, when the second shaft 22 is rotated under force, the slot wall of the fourth slot applies force to the fourth boss, so that the fourth boss moves, that is, the second inner wall 321 rotates with the rotation of the second shaft 22. When the second inner wall 321 is rotated under force, at this time, the fourth boss applies force to the slot wall of the fourth slot, so that the slot wall of the fourth slot moves, that is, the second shaft 22 rotates with the rotation of the second inner wall 321.

[0054] That is, by providing a third slot on the first inner wall 311, providing a third boss on the first rotating shaft 21, and the third boss being engaged in the third slot, the first inner wall 311 can drive the first rotating shaft 21 to rotate, or the first rotating shaft 21 can drive the first inner wall 311 to rotate. Similarly, by providing a fourth slot on the second inner wall 321, providing a fourth boss on the second rotating shaft 22, and the fourth boss being engaged in the fourth slot, the second inner wall 321 can drive the second rotating shaft 22 to rotate, or the second rotating shaft 22 can drive the second inner wall 321 to rotate.

[0055] Of course, in the embodiment of the present application, the first inner wall 311 is provided through the first rotating shaft 21, and the first inner wall 311 and the first rotating shaft 21 can be interference fit, so that the first inner wall 311 drives the first rotating shaft 21 to rotate, or the first rotating shaft 21 drives the first inner wall 311 to rotate. Similarly, the second inner wall 321 is provided through the second rotating shaft 22, and the second inner wall 321 and the second rotating shaft 22 can be interference fit, so that the second inner wall 321 drives the second rotating shaft 22 to rotate, or the second rotating shaft 22 drives the second inner wall 321 to rotate.

[0056] In addition, in some embodiments, the rotating mechanism may further include a supporting assembly 50. Both ends of the supporting assembly 50 are respectively matched with the transmission fluid cylinder assembly 30.

[0057] Since both ends of the support assembly 50 are respectively matched with the transmission cylinder assembly 30, the support assembly 50 can support the transmission cylinder assembly 30, thereby supporting the rotating assembly 10, thereby avoiding the problem of the rotating assembly 10 having an excessively large unfolding angle when the rotating assembly 10 switches between the unfolded state and the folded state.

[0058] It should be noted that, when the transmission cylinder assembly 30 includes a first cylinder body 31 and a second cylinder body 32 , at this time, the first cylinder body 31 and the second cylinder body 32 can be matched with two ends of the support assembly 50 respectively.

[0059] In the embodiment of the present application, since the first rotating shaft 21 and the second rotating shaft 22 are arranged at intervals, and the first rotating shaft 21 and the second rotating shaft 22 are both fixedly connected to the rotating shaft assembly 20, the rotating assembly 10 can drive the first rotating shaft 21 and / or the second rotating shaft 22 to rotate. Since the first end of the transmission fluid cylinder assembly 30 is sleeved on the first rotating shaft 21, the second end of the transmission fluid cylinder assembly 30 is sleeved on the second rotating shaft 22, and the transmission fluid is stored in the transmission fluid cylinder assembly 30, when the rotating assembly 10 drives the first rotating shaft 21 to rotate, the first rotating shaft 21 can drive the transmission fluid to flow in the transmission fluid cylinder assembly 30, and the transmission fluid is incompressible, so that the second rotating shaft 22 is synchronously rotated through the transmission fluid, so that the rotating assembly 10 switches between the unfolded state and the folded state. That is, in the embodiment of the present application, the transmission fluid cylinder assembly 30 is sleeved on the first rotating shaft 21 and the second rotating shaft 22, so that when the rotating assembly 10 drives the first rotating shaft 21 to rotate, the first rotating shaft 21 causes the transmission fluid in the transmission fluid cylinder assembly 30 to flow, so that the second rotating shaft 22 rotates synchronously, so that the rotating assembly 10 switches between the unfolded state and the folded state, thereby avoiding the problem that a more complex gear structure is connected to the rotating shaft assembly 20, so that the rotating assembly 10 switches between the folded state and the unfolded state, and the two ends of the rotating assembly 10 cannot move synchronously.

[0060] An embodiment of the present application provides an electronic device, which includes the rotating mechanism in any one of the above embodiments.

[0061] It should be noted that in the embodiment of the present application, the electronic device includes a first shell and a second shell, and the rotating component 10 in the rotating mechanism is respectively connected to the first shell and the second shell. When the rotating component 10 switches between the unfolded state and the folded state, the rotating component 10 drives the first shell and the second shell to move closer to or away from each other, so that the electronic device switches between the unfolded state and the folded state.

[0062] In addition, when the rotating assembly 10 includes the first rotating plate 11 and the second rotating plate 12 , at this time, the first rotating plate 11 may be connected to the first housing, and the second rotating plate 12 may be connected to the second housing.

[0063] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

Therefore, the appended claims are intended to be interpreted as including optional embodiments and all changes and modifications that fall within the scope of the present application.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that an article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such article or terminal device.
