[0048] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0049] In the related art, a foldable electronic device switches between a folded state and an unfolded state by applying force to the electronic device from the outside, for example, a user folds or unfolds the electronic device by himself.

[0050] However, relying on users to switch the electronic device between a folded state and an unfolded state is not conducive to the intelligent development of the electronic device.

[0051] In order to solve the above technical problem, a folding assembly 1 is provided according to an embodiment of the present disclosure.

[0052] Figure 1 It is a schematic structural diagram of a folding assembly according to an exemplary embodiment. Figure 2 It is a schematic structural diagram of a driving mechanism according to an exemplary embodiment.

[0053] In some embodiments, Figure 1 As shown, the folding assembly 1 mainly includes a plurality of shells 2 , a rotating shaft 3 and a driving mechanism 4 .

[0054] like Figure 1 or Figure 2 As shown, two adjacent housings 2 among the plurality of housings 2 are rotatably connected to opposite sides of the rotating shaft 3, and at least a portion of the driving mechanism 4 can be connected to the housing 2. The driving mechanism 4 can have a first form and a second form, and the driving mechanism 4 drives the two adjacent housings 2 to rotate relative to the rotating shaft 3 when switching between the first form and the second form.

[0055] The folding assembly 1 can have an unfolded state and a folded state. When the driving mechanism 4 is in a first state, the folding assembly 1 can be in an unfolded state. When the driving mechanism 4 is in a second state, the folding assembly 1 can be in a folded state.

[0056] In this embodiment, at least a portion of the drive mechanism 4 that can change its shape is connected to multiple housings 2, and the drive mechanism 4 can transmit the force of the drive mechanism 4 to the housing 2 through the portion connected to the housing 2. When the drive mechanism 4 changes its shape, it drives at least one housing 2 to rotate relative to the rotating shaft 3, so as to realize the automatic folding or unfolding of the folding assembly 1 and / or the electronic device 100. In addition, since the drive mechanism 4 that can change its shape does not need an additional transmission device to cooperate with the housing 2, it occupies less space, which is conducive to the trend of thinning and lightening of the electronic device 100.

[0057] It should be noted that, in a possible case, the multiple shells 2 can be two, and the two shells 2 are rotatably arranged on the rotating shaft 3, and the folding or unfolding of the folding assembly 1 is achieved by rotating at least one of the two shells 2 relative to the rotating shaft 3.

[0058] However, the present disclosure is not limited to this. In another possible case, the multiple shells 2 can also be any number of three or more, and the multiple shells 2 can be rotatably arranged on the rotating shaft 3. The folding or unfolding of the folding component 1 can also be achieved by rotating at least one shell 2 among the multiple shells 2 relative to the rotating shaft 3.

[0059] It is understandable that the present disclosure does not specifically limit the specific number of the multiple shells 2. The above situation is only an exemplary description of the number of multiple shells 2, but is not limited to the situation described in the above embodiment. As long as there are two or more, it is fine. In other words, as long as it is under this condition, those skilled in the art can adjust the specific number of the multiple shells 2 according to the actual situation.

[0060] It should be noted that the multiple shells 2 can be folded by rotating the shaft 3. In a possible case, Figure 1 As shown, the rotating shaft 3 may be a physical rotating shaft 3 , and at least one shell 2 among the plurality of shells 2 may rotate relative to the physical rotating shaft 3 .

[0061] However, the present disclosure is not limited thereto. In another possible case, the rotation axis may also be a virtual rotation axis. When the rotation axis is a virtual rotation axis, the rotation axis is not completely composed of physical components of the folding assembly 1, but is a virtual rotation line formed by shape constraints and displacement constraints of different components in the folding assembly 1 during relative movement. When the multiple shells 2 of the folding assembly 1 move relatively, at least one shell 2 among the multiple shells 2 will rotate relatively around the virtual rotation axis.

[0062] It is understandable that the present disclosure does not specifically limit the specific form of the rotating shaft. The above situation is only an exemplary description of the forms in which the rotating shaft can exist, but is not limited to the situations described in the above embodiments. As long as at least one of the multiple shells 2 can rotate relative to the rotating shaft. In other words, as long as this condition is met, those skilled in the art can adjust the specific form of the rotating shaft according to actual conditions.

[0063] It should be noted that the driving mechanism 4 can be a component that generates power, and the driving mechanism 4 can convert energy into mechanical energy. The driving mechanism 4 can connect multiple shells 2, so as to transmit mechanical energy to at least one shell 2 among the multiple shells 2, thereby driving at least one shell 2 to rotate.

[0064] The driving mechanism 4 can have a first form and a second form, and the first form and the second form can be two different shape states of the driving mechanism 4. The first form and the second form can be converted into each other, and the transition between the two shape states can drive relative movement between multiple shells 2, thereby realizing the unfolding or folding of the folding component 1.

[0065] As can be seen from the above, in the exemplary embodiment of the present disclosure, the driving mechanism 4 may include at least one of a shape memory alloy, an electroactive polymer, or a shape memory composite material. In the following description, the shape memory alloy is used as an example, but the present disclosure is not limited thereto.

[0066] The first form and the second form of the driving mechanism 4 can be converted into each other. When the driving mechanism 4 is in the first form, the folding component can be in the unfolded state, or the folding component can also be in the folded state. Since the driving mechanism 4 is connected to multiple shells 2, when the driving mechanism 4 is deformed from the first form to the second form, it can drive at least one shell 2 among the multiple shells 2 to rotate relative to the rotating shaft 3 to realize the transformation of the folding component 1 from the unfolded state to the folded state, or realize the transformation of the folding component 1 from the folded state to the unfolded state.

[0067] Among them, shape memory alloys (Shape Memory Alloys, SMA) are metal materials with shape memory effect. Shape memory alloys can undergo phase change at a specific temperature, thereby changing their shape. It can be understood that the shape memory alloys disclosed in the present invention can be titanium-nickel alloys, copper-based alloys, nickel-cobalt alloys, etc., but the present disclosure does not specifically limit the type of shape memory alloys, that is, those skilled in the art can adjust the type according to actual conditions, as long as the material can undergo phase change, thereby changing its shape.

[0068] Electroactive polymer (EAP) is a polymer material that can produce deformation or movement through electric field stimulation. The electroactive polymer disclosed in the present invention may include ion conductive electroactive polymer, electrostrictive electroactive polymer (such as polyvinylidene fluoride PVDF, polyaniline PANI), electrochemically active electroactive polymer (such as polypyrrole PPY) or piezoelectric electroactive polymer (such as polymethyl methacrylate PMMA), etc., but the present disclosure does not specifically limit the type of electroactive polymer, that is, those skilled in the art can adjust its type according to actual conditions, as long as the material can produce deformation or movement through electric field stimulation.

[0069] The shape memory composite material can be a composite material of shape memory alloy and elastomer, a composite material of shape memory alloy and plastic, a composite material of shape memory alloy and ceramic, or a composite material of shape memory alloy and carbon fiber, etc., but the present disclosure does not specifically limit the type of shape memory composite material, that is, those skilled in the art can adjust its type according to actual conditions.

[0070] Figure 3 is an exploded view of a first driving mechanism according to an exemplary embodiment.

[0071] In some embodiments, Figure 3 As shown, the driving mechanism 4 may include a first driving mechanism 41, and the first driving mechanism 41 may include a plurality of first connecting parts 42 and a deformation part 43. The plurality of first connecting parts 42 may be connected to the plurality of shells 2 one by one, and the deformation part 43 may be located between the plurality of first connecting parts 42. When the deformation part 43 is deformed, the first driving mechanism 41 may be deformed from the first form to the second form.

[0072] In this embodiment, the mechanical connection between the first driving mechanism 41 and the multiple shells 2 is realized by multiple first connecting parts 42. The deformation part 43 is located between the first connecting parts 42. When the shape of the deformation part 43 changes, the movement and deformation of the deformation part 43 can be directly transmitted to the first connecting parts 42 connected on both sides, and then transmitted to the corresponding shell 2 by the first connecting parts 42, thereby driving the shell 2 to produce relative movement.

[0073] Specifically, the first connection portion 42 can serve as a mechanical arm extending from the deformation portion 43 to both sides, transmitting the deformation movement of the deformation portion 43 to the corresponding shell 2 connected to the other end thereof, thereby driving the shell 2 to generate relative movement.

[0074] In some embodiments, when the first driving mechanism 41 is at a predetermined temperature, the driving mechanism 4 can switch the form.

[0075] It should be noted that the first drive mechanism 41 may include a one-way shape memory alloy, and when the first drive mechanism 41 is heated to a predetermined temperature, it may be deformed, for example, from a first shape to a second shape. When the first drive mechanism 41 is cooled, it may maintain the shape after heating, or it may be transformed from the second shape to the first shape by an external force.

[0076] In this embodiment, by switching the form of the first driving mechanism 41, the driving mechanism 4 can be transformed from the first form to the second form, and then the folding component 1 can be transformed from the unfolded state to the folded state, thereby realizing automatic folding of the folding component 1.

[0077] It should be noted that the predetermined temperature can be the temperature value required for the first drive mechanism 41 to deform. Specifically, when the first drive mechanism 41 is heated to this predetermined temperature, it can be deformed from the first form to the second form. The predetermined temperature is a controllable parameter and can be predetermined in the following ways, for example: according to the material properties of the drive mechanism 4, its phase change temperature or softening temperature is predetermined as the predetermined temperature, or the temperature threshold required for the deformation of the drive mechanism 4 is obtained through testing and set as the predetermined temperature, or the material properties, geometric structure, loading conditions and other factors of the drive mechanism 4 are combined to predict the temperature required for deformation by finite element simulation, and set it as the predetermined temperature, or a temperature control system is set to monitor the temperature of the drive mechanism 4 in real time, and the temperature value recorded at the beginning of the deformation is the predetermined temperature. In the above manner, the temperature value that causes the deformation of the drive mechanism 4 can be predetermined to guide the subsequent heating control, so that the temperature control of the drive mechanism 4 can be achieved in a targeted manner.

[0078] In one possible scenario, Figure 3 As shown, the multiple first connection parts 42 can be two, the multiple shells 2 can be two, the two first connection parts 42 are respectively connected to the two shells 2, and the deformation part 43 can be located between the two first connection parts 42. When the driving mechanism 4 is in the first form, when the first driving mechanism 41 is at a predetermined temperature, the deformation part 43 can be deformed. At this time, the first driving mechanism 41 can be deformed from the first form to the second form. The first driving mechanism 41 is mechanically connected with the multiple shells 2 through the first connection part 42, thereby transmitting the motion to the multiple shells 2, thereby driving the multiple shells 2 to move relative to the rotating shaft 3, and then the folding component 1 is transformed from the unfolded state to the folded state.

[0079] However, the present disclosure is not limited thereto. In another possible case, the number of the multiple shells 2 may be three or more, and the number of the multiple first connection parts 42 corresponds to the number of the multiple shells 2, that is, the number of the multiple first connection parts 42 may be three or more. The deformation part 43 connects the multiple first connection parts 42, and when the deformation part 43 is deformed, it can also transmit the motion to the multiple first connection parts 42, so that the multiple first connection parts 42 are correspondingly transmitted to the multiple shells 2.

[0080] It is understandable that the present disclosure does not specifically limit the specific number of the multiple first connection parts 42. The above situation is only an exemplary description of the number of the multiple first connection parts 42, but is not limited to the situation described in the above embodiment. As long as there are two or more, it is fine. In other words, as long as it is under this condition, those skilled in the art can adjust the specific number of the multiple first connection parts 42 according to the actual situation.

[0081] In some embodiments, Figure 3 As shown, the deformation portion 43 may include a first deformation portion 431 and a second deformation portion 432 . The first deformation portion 431 may be located on a first side of the first driving mechanism 41 , and the second deformation portion 432 may be located on a second side of the first driving mechanism 41 .

[0082] In this embodiment, by arranging the first deformation part 431 and the second deformation part 432 on different sides of the first driving mechanism 41 , the deformation of the first driving mechanism 41 can be made more uniform and controllable, and the mechanical strength of the first driving mechanism 41 can be enhanced.

[0083] In some embodiments, at least one of the first deforming portion 431 and the second deforming portion 432 may be arc-shaped.

[0084] In a first possible case, the first deformation portion 431 may be arc-shaped, and the second deformation portion 432 may be in other shapes.

[0085] In a second possible case, the first deformation portion 431 may be in other shapes, and the second deformation portion 432 may be in an arc shape.

[0086] In a third possible case, the first deformation portion 431 may be arc-shaped, and the second deformation portion 432 may also be arc-shaped.

[0087] Specifically, in some embodiments, Figure 3As shown, when the folding component 1 is in the unfolded state, the bending direction of the first deformation portion 431 can be the first direction D1, and the bending direction of the second deformation portion 432 can be the second direction D2. When the folding component 1 is in the folded state, the bending direction of the first deformation portion 431 can be the first direction D1, and the bending direction of the second deformation portion 432 can be the first direction D1. The first direction D1 can be opposite to the second direction D2.

[0088] It should be noted that the bending direction refers to the direction in which the convex surface (convex part) of the deformable portion 43 faces when the deformable portion 43 is bent. For example, when the first deformable portion 431 convexes downward, the bending direction is the downward direction.

[0089] In this embodiment, when the folding assembly 1 is in the unfolded state, the first deformable portion 431 bends toward the first direction D1, that is, the convex surface of the first deformable portion 431 faces the first direction D1, and the second deformable portion 432 can bend toward the second direction D2, that is, the convex surface of the second deformable portion 432 faces the second direction D2. The convex surfaces of the first deformable portion 431 and the second deformable portion 432 face opposite directions, which can produce twisting deformation and output a larger driving force.

[0090] Specifically, when the folding assembly 1 is in the unfolded state, the convex surface of the first deformable portion 431 faces the first direction D1, and the convex surface of the second deformable portion 432 faces the second direction D2. The convex surfaces of the two deformable portions 43 face opposite directions, which can produce twisting deformation and output a larger driving force.

[0091] When the first driving mechanism 41 is transformed from the first form to the second form, the first deformable portion 431 increases the curvature of the bending, and the second deformable portion 432 changes the bending direction and bends in the opposite direction. This coordinated deformation can generate a larger output torque, which is beneficial to the transformation of the folding assembly 1 from the unfolded state to the folded state. When the first driving mechanism 41 is in the second form, that is, when the folding assembly 1 is in the folded state, the bending directions of the two deformable portions 43 can both be the first direction D1, which is beneficial to the reset of the deformable portion 43 and prepares for the next round of unfolding.

[0092] Compared with a single bending direction structure, the first deformation portion 431 and the second deformation portion 432 have different bending directions, which can have a larger deformation amount and higher output energy during twisting deformation.

[0093] In some embodiments, Figure 3 As shown, there may be a gap 433 between the first deformation portion 431 and the second deformation portion 432 .

[0094] In this embodiment, a gap 433 is formed between the first deformation portion 431 and the second deformation portion 432. The gap 433 allows the first deformation portion 431 and the second deformation portion 432 to move relative to each other within a certain range without constraining each other, which is conducive to the relative independent deformation of the first deformation portion 431 and the second deformation portion 432 and avoids mutual constraints between the two.

[0095] In some embodiments, Figure 3 As shown, the first driving mechanism 41 may further include a first heating element 44. The first heating element 44 may be disposed on the deformation portion 43. The first heating element 44 may be used to heat the temperature of the deformation portion 43 to a predetermined temperature.

[0096] In this embodiment, the deformation portion 43 is heated by the first heating element 44 , so that the deformation portion 43 can be deformed, thereby realizing the deformation of the driving mechanism 4 from the first form to the second form.

[0097] The first heating element 44 may be a resistance wire, an electric heating film, a heat conducting element, etc., but the present disclosure does not specifically limit the specific type of the first heating element 44, that is, those skilled in the art may adjust its type according to actual conditions. For example, taking the first heating element 44 as a resistance wire as an example, as long as the first heating element 44 can heat the deformation part 43 to cause the deformation part 43 to deform, it can be used.

[0098] In an exemplary embodiment of the present disclosure, the working principle of the first driving mechanism 41 is as follows.

[0099] The first heating element 44 can be a resistance wire heating sheet structure, which is bonded to the shape memory alloy folding structure by double-sided tape or dispensing tape. The first heating element 44 is responsible for heating the shape memory alloy folding structure so that it can deform when heated to the rated temperature, thereby realizing the deformation of the shape memory alloy driving structure and further realizing the folding action of the folding component 1.

[0100] The two ends of the shape memory alloy are hard-connected to the housing 2 by means of screws or glue dispensing, and the middle structure of the shape memory alloy is shaped as follows: Figure 3 As shown, the middle is designed with folding redundancy to ensure that the folding assembly 1 can be folded normally. The redundancy form is not limited to the following: Figure 3 The original state of shape memory alloy is as follows Figure 3 In the straight line unfolded state shown, after being heated, the shape memory alloy structure folds, driving the two shells 2 to fold. This shape memory alloy is a one-way memory alloy, which deforms after heating and will not return to its original shape after cooling, and can be restored to its original shape by external force.

[0101] Figure 4 The diagram is a structural perspective view of a second driving mechanism according to an exemplary embodiment viewed from the rear side. Figure 5 The diagram is a structural perspective view of a second driving mechanism according to an exemplary embodiment viewed from the front side. Figure 6 is a structural perspective view of a second driving mechanism and a housing according to an exemplary embodiment.

[0102] In some embodiments, the drive mechanism 4 may include a second drive mechanism 45, such as Figure 6 As shown, at least a portion of the second driving mechanism 45 can be connected to the housing 2, and when the second driving mechanism 45 is at a predetermined temperature, the driving mechanism 4 can switch the form.

[0103] It should be noted that the second driving mechanism 45 may include a one-way shape memory alloy, and when the second driving mechanism 45 is heated to a predetermined temperature, it may be deformed, for example, from the second shape to the first shape. When the second driving mechanism 45 is cooled, it may maintain the shape after heating, or it may be transformed from the first shape to the second shape by an external force.

[0104] In this embodiment, at least a portion of the second driving mechanism 45 is connected to the shell 2, and the second driving mechanism 45 can transmit the force of the second driving mechanism 45 to the shell 2 through the portion connected to the shell 2. When the temperature of the second driving mechanism 45 reaches a predetermined temperature, the shape of the second driving mechanism 45 changes, and the force of the shape change is transmitted to the shell 2. The shell moves with the shape change of the second driving mechanism 45. Under the action of the movement of the shell 2, the shape of the driving mechanism 4 can also change accordingly, so that the folding component 1 can be changed from a folded state to an unfolded state, thereby realizing automatic unfolding of the folding component 1.

[0105] It should be noted that the predetermined temperature may also be a temperature value required for the second driving mechanism 45 to deform. For example, when the second driving mechanism 45 is heated to the predetermined temperature, deformation from the second form to the first form will occur. It should be noted that the predetermined method of the predetermined temperature can refer to the description of the aforementioned embodiment, and the present disclosure will not repeat it here.

[0106] In some embodiments, Figure 4 or Figure 5 As shown, the second driving mechanism 45 may include multiple second connecting parts 451, a fixed part 452 and a plurality of bendable parts 453, the multiple second connecting parts 451 may be connected to the multiple shells 2, the fixed part 452 may be arranged on the rotating shaft 3, and the multiple bendable parts 453 may be arranged between the fixed part 452 and the multiple second connecting parts 451.

[0107] In this embodiment, the second connecting portion 451 of the second driving mechanism 45 can be connected to the multiple housings 2 in a one-to-one correspondence, so as to realize the connection between the second driving mechanism 45 and the multiple housings 2. The fixed portion 452 can be arranged on the rotating shaft 3, which is conducive to the stability of the second driving mechanism 45 relative to the rotating shaft 3. The multiple bendable portions 453 can be respectively arranged between the fixed portion 452 and the multiple second connecting portions 451, that is, the bendable portion 453 can realize the connection between the fixed portion 452 and the multiple second connecting portions 451, the bendable portion 453 can realize the shape change of the second driving mechanism 45, and the second connecting portion 451 can realize the transmission of motion.

[0108] In one possible scenario, Figure 6 As shown, the multiple second connection parts 451 can be two, the multiple shells 2 can be two, the two second connection parts 451 are respectively connected to the two shells 2, the fixed part 452 is arranged on the rotating shaft 3, the multiple bendable parts 453 can be two, the two bendable parts 453 are arranged between the fixed part 452 and the two second connection parts 451, when the driving mechanism 4 is in the second form, when the second driving mechanism 45 is at a predetermined temperature, the bendable part 453 can be deformed, at this time, the second driving mechanism 45 can be deformed from the second form to the first form, the second driving mechanism 45 drives the multiple shells 2 to move relative to the rotating shaft 3, and during the movement of the multiple shells 2, the first driving mechanism 41 is driven to change from the second form to the first form, thereby making the folding component 1 change from the folded state to the unfolded state.

[0109] However, the present disclosure is not limited thereto. In another possible case, the number of the multiple shells 2 may be any number of three or more, and the number of the multiple second connection parts 451 corresponds to the number of the multiple shells 2, that is, the number of the multiple second connection parts 451 may be any number of three or more. The multiple bendable parts 453 may correspond to the number of the multiple second connection parts 451, and the multiple bendable parts 453 may also transmit the motion to the multiple second connection parts 451 when deformed, so that the multiple second connection parts 451 transmit the motion to the multiple shells 2 accordingly.

[0110] It is understandable that the present disclosure does not specifically limit the specific number of the multiple second connection parts 451 and the multiple bendable parts 453. The above situation is only an exemplary description of the number of the multiple second connection parts 451 and the multiple bendable parts 453, but is not limited to the situation described in the above embodiment. As long as there are two or more, it is fine. In other words, as long as it is under this condition, those skilled in the art can adjust the specific number of the multiple second connection parts 451 and the multiple bendable parts 453 according to the actual situation.

[0111] In some embodiments, Figure 4 or Figure 5As shown, the second connection portion 451 may include a first limiting portion 4511 , the housing 2 may include a second limiting portion 201 , and the first limiting portion 4511 may be movably connected to the second limiting portion 201 .

[0112] In this embodiment, by movably connecting the first limiting portion 4511 with the second limiting portion 201, the first connecting portion 42 can allow a certain range of relative movement between the second connecting portion 451 and the shell 2 when transmitting the force to the shell 2. That is to say, the movable connection method can help the second connecting portion 451 to conform to and transmit the relative movement of the shell 2, which is beneficial to the matching of the movement between the second connecting portion 451 and the shell 2, improves the coordination of the drive, and can also avoid excessive stress between the second connecting portion 451 and the shell 2.

[0113] Specifically, in some exemplary embodiments of the present disclosure, when the folding assembly 1 is working, there will be relative movement between the multiple shells 2, and the relative movement will generate tension or pressure on the second connection part 451. If the second connection part 451 and the shell 2 are fixedly connected, the relative movement of the shell 2 will directly act on the second connection part 451, resulting in excessive stress. In this embodiment, the movably connected method allows the second connection part 451 to move relative to the shell 2 within a certain range. In other words, when the shell 2 produces relative movement, the second connection part 451 can move in a certain range in the direction of movement of the shell 2 due to the movably connected. This compliant movement can relieve the stress on the second connection part 451 and avoid the generation of excessive stress. At the same time, within the movable range, the second connection part 451 can still maintain connection with the shell 2 and continue to transmit the relative movement of the shell 2. In other words, through the "buffering" effect of this movably connected, it can be ensured that the second connection part 451 can both comply with the movement of the shell 2 and effectively transmit the movement of the shell 2, thereby realizing the driving function of the second connection part 451.

[0114] In some embodiments, Figure 6 As shown, the second driving mechanism 45 may further include a second heating element 454. The second heating element 454 may be disposed on the bendable portion 453. The second heating element 454 may be used to heat the bendable portion 453 to a predetermined temperature.

[0115] In this embodiment, the bendable portion 453 can be heated by the second heating element 454 to achieve temperature control of the bendable portion 453, that is, the bendable portion 453 is heated to a predetermined temperature by the second heating element 454, thereby achieving deformation of the bendable portion 453, and further achieving deformation of the driving mechanism 4 from the second form to the first form.

[0116] In a possible case, the second heating element 454 may be one, and one second heating element 454 may cover all of the multiple bendable portions 453, for example, Figure 6 As shown, the second heating member 454 is one, and the heating range of the second heating member 454 covers the plurality of bendable portions 453 , so that the plurality of bendable portions 453 can be heated to a predetermined temperature.

[0117] However, the present disclosure is not limited to this. In another possible case, there may be multiple second heating elements 454. The multiple second heating elements 454 may be arranged corresponding to the multiple bendable portions 453, and the multiple bendable portions 453 may be heated to a predetermined temperature.

[0118] Figure 7 is an exploded perspective view of a housing and a third driving mechanism according to an exemplary embodiment. Figure 8 is a structural perspective view of a third driving mechanism according to an exemplary embodiment.

[0119] In some embodiments, the plurality of shells 2 may include a first shell and a second shell. Figure 7 As shown, the driving mechanism 4 may include a third driving mechanism 46, which may be arranged on the first shell, and the first end 461 of the third driving mechanism 46 may be connected to the first shell. When the driving mechanism 4 is in the first form, the second end 462 of the third driving mechanism 46 may abut the second shell, and the third driving mechanism 46 is used to provide a force for the shell 2 to move relative to the rotating shaft 3.

[0120] In this embodiment, the third driving mechanism 46 can assist in the relative movement of the driving shell 2, which can make the process of switching the folding component 1 from the unfolded state to the folded state more controllable, and can increase the driving force of the driving mechanism 4 and improve the driving effect.

[0121] Specifically, during the operation of the folding assembly 1, when the unfolded state is changed to the folded state, a large resistance needs to be overcome between the multiple shells 2. The third drive mechanism 46 can assist the first drive mechanism 41 to jointly drive the movement of the shell 2. That is, the first end 461 of the third drive mechanism 46 can be set on the first shell, and the second end 462 can abut against the second shell. The third drive mechanism 46 can use its own deformation to push the first shell and the second shell to move relative to the rotation shaft 3, playing the role of "advanced drive".

[0122] That is to say, when the folding assembly 1 changes from the unfolded state to the folded state, the third driving mechanism 46 will generate a driving effect before the first driving mechanism 41. The driving effect of the third driving mechanism 46 occurs before the first driving mechanism 41, and the housing 2 is driven "in advance". This advance driving can play a "boosting" role, assisting the first driving mechanism 41 to jointly drive the housing 2. Through the advance driving of the third driving mechanism 46, the driving pressure of the first driving mechanism 41 can be reduced.

[0123] Among them, the third driving mechanism 46 may include shape memory alloys, electroactive polymers or shape memory composite materials, but the present disclosure does not specifically limit the specific type of the third driving mechanism 46, that is, those skilled in the art can adjust its type according to actual conditions. For example, taking the third driving mechanism 46 as a shape memory alloy as an example, as long as the third driving mechanism 46 can use its own deformation to drive the first shell and the second shell to move relative to the rotation axis 3, it can be used.

[0124] In one possible case, the third drive mechanism 46 may include a bidirectional shape memory alloy, and when the third drive mechanism 46 is heated to a predetermined temperature, it may be deformed and transformed from a first form to a second form. When the third drive mechanism 46 is not at the predetermined temperature, it may be restored to the first form. Specifically, the third drive mechanism 46 may be electrically connected to the power supply assembly, and after the power supply assembly inputs different currents or voltages into the third drive mechanism 46, the heat of the third drive mechanism 46 may change, and when the predetermined temperature is reached, the third drive mechanism 46 may achieve a shape transformation, from the first form to the second form.

[0125] However, the present disclosure is not limited thereto. In another possible case, the third driving mechanism 46 may also include a one-way shape memory alloy. When the third driving mechanism 46 is heated to a predetermined temperature, it may be deformed and transformed from the first shape to the second shape. When the third driving mechanism 46 is not at the predetermined temperature, it may maintain the shape after heating, that is, the second shape, or it may be transformed from the second shape to the first shape by an external force.

[0126] It is understandable that the present disclosure does not specifically limit the specific type of the third drive mechanism 46. The above situation is only an exemplary description of the types of the third drive mechanism 46, but is not limited to the situation described in the above embodiment. As long as the third drive mechanism 46 can use its own deformation to drive the first shell and the second shell to move relative to the rotation axis 3. In other words, as long as this condition is met, those skilled in the art can adjust the specific type of the third drive mechanism 46 according to actual conditions.

[0127] Among them, the third drive mechanism 46 can be fixedly connected, assembled, etc. to the first shell, but the present disclosure does not specifically limit the connection method between the third drive mechanism 46 and the first shell, that is, technical personnel in this field can adjust its type according to actual conditions, as long as the third drive mechanism 46 can be relatively fixed to the first shell.

[0128] In one possible scenario, Figure 7 As shown, the first housing may be provided with a mounting portion 202 that matches the third drive mechanism 46, and the third drive mechanism 46 may be fixedly connected or assembled with the mounting portion 202. By providing the mounting portion 202 on the first housing, a space position that can accommodate the third drive mechanism 46 can be provided between the first housing and the second housing.

[0129] In some embodiments, Figure 8 As shown, the third driving mechanism 46 may include a telescopic portion 463, and the telescopic portion 463 may be located between the first end 461 and the second end 462. When the telescopic portion 463 is extended, the driving mechanism 46 may be deformed from the first form to the second form. The extension of the telescopic portion 463 may drive the overall form of the third driving mechanism 46 to change, and the telescopic portion 463 of the third driving mechanism 46 may realize the function of "pre-driving".

[0130] In some embodiments, when the driving mechanism 4 is in the first form, the driving mechanism 4 can be converted from the first form to the second form after receiving an electrical signal, and / or, when the driving mechanism 4 is in the second form, the driving mechanism 4 can be converted from the second form to the first form after receiving an electrical signal.

[0131] In the present disclosure, the driving mechanism 4 can trigger and control the shape transformation of the driving mechanism 4 by receiving an electrical signal, thereby realizing the control of automatic unfolding or folding of the folding component 1.

[0132] In one possible case, the first heating element 44 and / or the second heating element 454 in the driving mechanism 4 may be electrically controlled heating elements, that is, by inputting different currents or voltages into the first heating element 44 and / or the second heating element 454, the heat generation thereof changes to reach a predetermined temperature, and the driving mechanism 4 realizes the shape transformation after sensing the predetermined temperature.

[0133] Fig. 9 is a front view of a folding assembly according to another exemplary embodiment.

[0134] In some embodiments, there may be multiple driving mechanisms 4 , and at least a portion of each driving mechanism 4 may be connected to the housing 2 .

[0135] In this embodiment, at least a portion of each driving mechanism 4 may be connected to the housing 2. For example, in the first possible case of this embodiment, Fig. 9 As shown, the plurality of driving mechanisms 4 can be two, and the two driving mechanisms 4 can be respectively arranged at the upper and lower ends of the plurality of shells 2, so that the shells 2 can be driven cooperatively at the upper and lower ends. Specifically, the driving force can be distributed at both ends of the shell 2 to avoid the imbalance of single-end driving, and the driving force can also be increased, which is conducive to balancing the distribution of the driving force in the shell 2.

[0136] In a second possible case of this embodiment, one of the plurality of driving mechanisms 4 may also be disposed at a middle position of the housing 2 , and another driving mechanism 4 may also be disposed at any end point of the housing 2 .

[0137] It is understandable that the present disclosure does not specifically limit the specific setting positions of the multiple drive mechanisms 4. The above situation is only an exemplary description of the positions where the multiple drive mechanisms 4 can be set, but is not limited to the situation described in the above embodiment. As long as at least a part of each drive mechanism 4 is connected to the housing 2. In other words, as long as this condition is met, those skilled in the art can set and adjust the specific setting positions of the multiple drive mechanisms 4 according to actual conditions.

[0140] It can be understood that the folding assembly 1 involved in the present disclosure can be applicable to any electronic device 100 listed below.

[0141] It is understood that the electronic device 100 involved in the present disclosure may also be referred to as a terminal device, a terminal, a user equipment (UE), a mobile station (MS), an electronic device (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, the electronic device 100 may be a handheld device, a vehicle-mounted device, etc. with a wireless connection function. At present, examples of the electronic device 100 may include: a smart phone (MobilePhone), a pocket computer (Pocket Personal Computer, PPC), a handheld computer, a personal digital assistant (Personal Digital Assistant, PDA), a laptop computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the electronic device 100 may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the electronic device 100. In the following description, a mobile phone is taken as an example for explanation, but the present disclosure is not limited to this.

[0142] In some embodiments, Fig.10 As shown, the flexible display screen 110 can be connected to the housing 2 of the folding component 1, and the foldable portion 120 of the flexible display screen 110 can be arranged corresponding to the rotating shaft 3 of the folding component 1. With this arrangement, the folding state or unfolding state of the flexible display screen 110 can be synchronized with the folding component 1, thereby realizing the automatic folding or unfolding of the folding electronic device 100.

[0143] Among them, the flexible display screen 110 can be a flexible OLED display screen, a flexible QLED display screen or a flexible Micro-LED display screen, etc., but the present disclosure does not specifically limit the type of the flexible display screen 110, that is, those skilled in the art can adjust its type according to actual conditions. For example, taking the flexible display screen 110 as a flexible OLED display screen as an example, as long as the flexible display screen 110 has a foldable portion 120, it can be used.

[0144] In some embodiments, the electronic device 100 may further include a main board (not shown), which may be electrically connected to the driving mechanism 4 of the folding assembly 1 .

[0145] In this embodiment, the driving mechanism 4 can be powered or sent a control signal through the mainboard, and the driving mechanism 4 can work under the control of the mainboard, which is beneficial for the electronic device 100 to achieve system-level intelligent control of the folding component 1.

[0146] Based on the same concept, an embodiment of the present disclosure further provides an accessory for an electronic device, wherein the accessory for an electronic device includes the folding assembly 1 of any one of the above embodiments.

[0149] The embodiment of the disclosure is connected to multiple housings 2 through a drive mechanism 4 that can change its shape. When the shape of the drive mechanism 4 changes, it drives at least one housing 2 to rotate relative to the rotating shaft 3, so as to realize the automatic folding or unfolding of the folding assembly 1 and / or the electronic device 100. In addition, since the drive mechanism 4 that can change its shape does not require an additional transmission device to cooperate with the housing 2, it occupies less space, which is conducive to the trend of thinning and lightening of the electronic device 100.

[0150] It is to be understood that in the present disclosure, "plurality" refers to two or more than two, and other quantifiers are similar.
