[0056] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0057] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0058] The embodiments of this application will now be described in detail.

[0059] like Figure 1 , Figure 2 and Figure 13 As shown, this application provides an electrically driven folding device, including an electric drive assembly 10, a transmission assembly 20, a first connector 30, and a second connector 40. The transmission assembly 20 is connected to the electric drive assembly 10, and the electric drive assembly 10 provides power output to the transmission assembly 20. The first connector 30 and the second connector 40 are respectively connected to the transmission assembly 20, with the first connector 30 extending towards a first side of the transmission assembly 20 and the second connector 40 extending towards a second side of the transmission assembly 20 opposite to the first side. The transmission assembly 20 transmits power to at least one of the first connector 30 and the second connector 40. The first connector 30 can be used to connect to a first body 80, and when the first connector 30 is connected to the transmission assembly 20, the first connector 30 transmits power to the first body 80, causing the first body 80 to rotate. The second connector 40 can be used to connect to a second body 90, and when the second connector 40 is connected to the transmission assembly 20, the second connector 40 transmits power to the second body 90, causing the second body 90 to rotate.

[0060] In some embodiments, the electric folding device further includes a fixing housing 60 for supporting and fixing the electric folding device. The electric drive assembly 10 and the transmission assembly 20 are both fixedly connected to the fixing housing 60.

[0061] In some embodiments, the surface of the fixed shell 60 is arc-shaped, which can shield and protect the internal components of the electric folding device, thereby improving the aesthetics and reliability of the electric folding device.

[0062] The electric drive assembly 10 drives at least one of the first connecting member 30 and the second connecting member 40 to rotate via the transmission assembly 20, thereby unfolding or folding the electric folding device. In some embodiments, the electric drive assembly 10 drives the first connecting member 30 to rotate via the transmission assembly 20, while the second connecting member 40 remains stationary. In other embodiments, the electric drive assembly 10 drives the second connecting member 40 to rotate via the transmission assembly 20, while the first connecting member 30 remains stationary. In still other embodiments, the electric drive assembly 10 can drive the first connecting member 30 and the second connecting member 40 to rotate synchronously via the transmission assembly 20. For example, the first connecting member 30 and the second connecting member 40 rotate synchronously in opposite directions, wherein the rotation angles of the first connecting member 30 and the second connecting member 40 during synchronous rotation can be the same or different, thereby improving transmission efficiency and making the folding method of the electric folding device more flexible.

[0063] The angle between the first body and the second body can be 0°-90°, or 0°-180°, etc. In some embodiments, the rotation angle range of the first connector 30 and / or the second connector 40 is 0°-90°. In other embodiments, the rotation angle range of the first connector 30 and / or the second connector 40 can be 0°-180°. In still other embodiments, the rotation angle range of the first connector 30 and / or the second connector 40 can be 0°-45°. The rotation range of the first connector 30 and the second connector 40 is not limited here.

[0064] In some embodiments, the electrically folding device may have an unfolded state and a folded state. In the unfolded state, the first connecting member 30 and the second connecting member 40 extend in opposite directions and are parallel or approximately parallel. Correspondingly, the first connecting member 30 and the second connecting member 40 may be at a 180° or approximately 180° angle. In the folded state, the first connecting member 30 extends perpendicularly to or approximately perpendicularly to the second connecting member 40. Correspondingly, the first connecting member 30 and the second connecting member 40 are at a 90° or approximately 90° angle. Alternatively, in the folded state, the first connecting member 30 and the second connecting member 40 extend in the same direction and are parallel or approximately parallel. Correspondingly, the first connecting member 30 and the second connecting member 40 may be at a 0° or approximately 0° angle, for example, the first connecting member 30 and the second connecting member 40 may be stacked, etc. The specific implementation of the unfolded and folded states of the electrically folding device is not limited in the embodiments of this application.

[0065] In some embodiments, the electric drive assembly 10 includes a motor 11 and a gearbox 12 disposed on at least one side of the motor 11. The gearbox 12 is connected to the transmission assembly 20 via an output shaft 13. Optionally, the gearbox 12 includes multiple sets of planetary gears for increasing torque. One end of the output shaft 13 is connected to the gearbox 12, and the other end is connected to the transmission assembly 20. In some examples, the transmission assembly 20 includes at least one gear 23, and the output shaft 13 can be connected to at least one gear 23 to output power to at least one gear 23. For example, the gear may include a body with a hole or groove in its central region and serrations on the periphery of the body. The output shaft 13 can be inserted into the hole or groove of the gear and output power to the gear, but the embodiments of this application are not limited to this.

[0066] In some embodiments, the electric drive assembly 10 further includes an electric drive fastener 14 for fixing the electric drive assembly 10 to the mounting housing 60. For example, the mounting housing 60 is provided with a fixing part 61, and the electric drive fastener 14 is bolted to the fixing part 61. However, this application does not limit the fixing method of the electric drive fastener 14.

[0067] Please refer to Figures 3 to 5 In some embodiments, the transmission assembly 20 includes at least one of a first transmission member 21 and a second transmission member 22. The first transmission member 21 is connected to a first connecting member 30, for example, in a fixed or movable connection, and the second transmission member 22 is connected to a second connecting member 40, for example, in a fixed or movable connection. The electric drive assembly 10 is used to drive at least one of the first transmission member 21 and the second transmission member 22 to rotate, thereby driving the first connecting member 30 connected to the first transmission member 21 and / or the second connecting member 40 connected to the second transmission member 22 to rotate.

[0068] In some embodiments, the first transmission member 21 and the second transmission member 22 may be symmetrically arranged, and / or the first connector 30 and the second connector 40 may be symmetrically arranged on both sides of the transmission assembly 20, but the embodiments of this application are not limited thereto.

[0069] In such Figure 6 In the example shown, at least one of the first transmission member 21 and the second transmission member 22 includes a gear portion 201 and a torsion bar portion 202. The gear portion 201 may include one or more gears for rotating under the drive of the electric drive assembly 10. One end of the torsion bar portion 202 is connected to the gear portion 201 and can move as the gear portion 201 rotates. The other end of the torsion bar portion 202 is connected to the first connector 30 or the second connector 40 for driving the first connector 30 or the second connector 40 to rotate.

[0070] In some embodiments, the gear portion 201 and the torsion bar portion 202 are fixedly connected. For example, the torsion bar portion 202 includes a connector for fixing the torsion bar portion 202 to the gear portion 201. Alternatively, the gear portion 201 and the torsion bar portion 202 may be integrally formed, but the embodiments of this application are not limited thereto.

[0071] exist Figure 4 In the example shown, the first transmission member 21 includes a first torsion bar 212 and a first gear 211 fixedly connected to the first torsion bar 212, and the first torsion bar 212 is movably connected to the first connecting member 30. The second transmission member 22 includes a second torsion bar 222 movably connected to the second connecting member 40 and a second gear 221 fixedly connected to the second torsion bar 222. In other examples, at least one of the first transmission member 21 and the second transmission member 22 may also include other gears, and this application embodiment does not limit this.

[0072] In some embodiments, the first transmission member 21 is connected to the second transmission member 22, and the electric drive assembly 10 is connected to one of the first transmission member 21 and the second transmission member 22. The first transmission member 21 and the second transmission member 22 connected to the electric drive assembly 10 are used to transmit power to the other. As an example, the electric drive assembly 10 is connected to the first transmission member 21 and can be used to output power to the first transmission member 21. The first transmission member 21 can be used to drive the first connecting member 30 while simultaneously transmitting power to the second transmission member 22, causing the second transmission member 22 to drive the second connecting member 40.

[0073] exist Figure 4In the example shown, the first transmission component 21 and the second transmission component 22 respectively include a first gear 211 and a second gear 221. The first gear 211 can mesh with the second gear 221 to achieve power transmission. As an example, the output shaft 13 of the electric drive assembly 10 is connected to the first gear 211. Thus, the electric drive assembly 10 drives the first gear 211 to rotate, and the rotation of the first gear 211 drives the first torsion bar 212 connected to it to rotate, which in turn drives the first connecting member 30 to rotate. At the same time, the rotation of the first gear 211 drives the second gear 221 meshing with it to rotate, and the rotation of the second gear 221 drives the second torsion bar 222 connected to it to rotate, which in turn drives the second connecting member 40 to rotate.

[0074] In some embodiments, the transmission assembly further includes at least one gear 23, which comprises one or more meshing gears. The at least one gear 23 is located between and connected to the first transmission member 21 and the second transmission member 22, respectively. The electric drive assembly 10 is connected to the at least one gear 23, so that the at least one gear 23 can transmit power output from the electric drive assembly 10 to the first transmission member 21 and the second transmission member 22. For example, the at least one gear 23 may include a gear meshing with the gear of the first transmission member 21, a gear meshing with the gear of the second transmission member 22, and a gear connected to the electric drive assembly 10 to achieve power transmission. At least two of the gear meshing with the gear of the first transmission member 21, the gear meshing with the gear of the second transmission member 22, and the gear connected to the electric drive assembly 10 may be the same or different. Figure 4In the illustrated embodiment, at least one gear 23 includes two meshing gears, namely a third gear 231 and a fourth gear 232. The electric drive assembly 10 is connected to the third gear 231; for example, the output shaft 13 of the electric drive assembly 10 is connected to the third gear 231. The third gear 231 meshes with the first gear 211, and the fourth gear 232 meshes with the second gear 221. Thus, the third gear 231 can transmit the power output from the electric drive assembly 10 to the first gear 211. The rotation of the first gear 211 drives the first torsion bar 212 connected to it to move, thereby driving the first connecting member 30 to move. Simultaneously, it can transmit the power output from the electric drive assembly 10 to the fourth gear 232, which in turn transmits it to the second gear 221 meshing with the fourth gear 232. The rotation of the second gear 221 drives the second torsion bar 222 connected to it to move, thereby driving the second connecting member 40 to move. The above examples illustrate the transmission assembly including at least one gear 23. In some embodiments, at least one of the first transmission member 21 and the second transmission member 22 includes two or more meshing gears. For example, the gear section 201 includes two or more meshing gears, and its transmission method is similar to the above examples, so it will not be described again here.

[0075] like Figure 3 As shown, in some embodiments, the transmission assembly 20 includes a first transmission section 26, a second transmission section 27, and a synchronizing rod 24 located between the first transmission section 26 and the second transmission section 27, wherein the two ends of the synchronizing rod 24 are respectively connected to the first transmission section 26 and the second transmission section 27. In some embodiments, the electric drive assembly 10 has only one output end. In this case, one of the first transmission section 26 and the second transmission section 27 is connected to the electric drive assembly 10, and is used to drive the synchronizing rod 24 to rotate under the drive of the electric drive assembly 10. The rotation of the synchronizing rod 24 drives the other of the first transmission section 26 and the second transmission section 27 to move, so as to realize the synchronous rotation of both sides of the electric folding device, making the movement of the electric folding device more stable and improving the transmission efficiency.

[0076] In the example shown in the attached figure, the synchronizing rod 24 is arranged parallel or approximately parallel to the output shaft 13 of the electric drive assembly 10. The first transmission part 26 and the second transmission part 27 are located at the left and right ends of the synchronizing rod 24, respectively. The first connecting member 30 and the second connecting member 40 are located on the upper and lower sides of the first transmission part 26 and / or the second transmission part 27, respectively, but this is not limited here.

[0077] The first transmission unit 26 and the second transmission unit 27 can be implemented in various ways. In some embodiments, at least one of the first transmission unit 26 and the second transmission unit 27 may include a gear transmission module 28 and at least one torsion bar transmission module 29. The gear transmission module may be connected to the electric drive assembly 10 or the synchronizing rod 24. One end of the torsion bar transmission module 29 is connected to the gear transmission module 28, and the other end is connected to the first connector 30 or the second connector 40. The gear transmission module 28 can rotate under the drive of the electric drive assembly 10 or the synchronous rod 24. The torsion bar transmission module is connected to the gear transmission module 28 and can move with the rotation of the gear transmission module. The torsion bar transmission module 29 is movably connected to the first connector 30 or the second connector 40, thereby driving the first connector 30 or the second connector 40 to move. For example, the torsion bar transmission module 29 can use the torque between itself and the first connector 30 or the second connector 40 to drive the first connector 30 or the second connector 40 to rotate.

[0078] The gear transmission module 28 may include one or more gears, such as at least one gear 23 in the above embodiments, or the gear section 201 in the above embodiments. The torsion bar transmission module 29 may include at least one torsion bar, such as the torsion bar section 202 in the above embodiments, or include a torsion bar and a gear fixedly connected. For example, the torsion bar transmission module 29 includes the first transmission member 21 and / or the second transmission member 22 in the above embodiments. In this case, at least one of the first transmission section 26 and the second transmission section 27 may further include or omit the gear transmission module 28, which is not limited here.

[0079] There are various ways to connect the synchronizing rod 24 and / or the electric drive assembly 10 to the gear transmission module 28. In some embodiments, the central region of one or more gears included in the gear transmission module 28 may be provided with a hole or groove, and the output shaft 13 of the synchronizing rod 24 and / or the electric drive assembly 10 is inserted into the hole or groove. In some embodiments, please refer to... Figure 7 In the example shown, the output shaft 13 of the electric drive assembly 10 has a flat structure 131 at its end. The shape of the hole or groove in the gear portion is adapted to the flat structure 131. The flat structure 131 is inserted into the hole or groove in the gear portion, so that the output shaft 13 and the gear portion are precisely matched, which enhances the stability of the connection and the torque transmission capability, while avoiding the slippage problem that may occur in traditional matching methods, thereby improving the overall system's working efficiency, durability and reliability.

[0080] In some embodiments, the end of the synchronizing rod 24 may also be provided with the above-mentioned flat structure 131, but the embodiments of this application are not limited thereto.

[0081] In some embodiments, at least one of the first transmission part 26 and the second transmission part 27 may include one or more torsion bar transmission modules 29, for example, two torsion bar transmission modules 29, which are movably connected to the first connector 30 and the second connector 40, respectively. In some embodiments, at least one of the first connector 30 and the second connector 40 may be sleeved on the torsion bar of the torsion bar transmission module 29, but the embodiments of this application are not limited thereto.

[0082] In this embodiment, the rotation axis of the torsion bar, torsion bar member, or torsion bar portion connected to the first connecting member 30 and / or the second connecting member 40 may be different from that of the first connecting member 30 and / or the second connecting member 40, causing relative movement between the two during rotation. Therefore, the transmission assembly 20 can be movably connected to the first connecting member 30 and / or the second connecting member 40. Please refer to... Figure 8 In the example shown, at least one of the first connector 30 and the second connector 40 is provided with a guide groove 32 to accommodate a torsion bar. The torsion bar can extend into the guide groove 32 and move along the guide groove 32. Thus, when the torsion bar moves with the rotation of the gear, it can drive the first connector 30 or the second connector 40 to rotate, and the torsion bar can slide within the guide groove 32. The torsion bar acts as a torque arm to realize the automatic folding or unfolding of the electric folding device.

[0083] In some embodiments, the electric folding device includes multiple first connectors 30 and second connectors 40. For example, the electric folding device includes first connectors 30 and second connectors 40 respectively connected to the first transmission part 26, and first connectors 30 and second connectors 40 connected to the second transmission part 27, but this is not limited here.

[0084] The first transmission section 26 and the second transmission section 27 may be arranged symmetrically with respect to the synchronizing rod 24. In some embodiments, the structures of the first transmission section 26 and the second transmission section 27 may be similar or identical, which is not limited here.

[0085] In some examples, the first transmission unit 26 includes a first torsion bar transmission module movably connected to the first connector 30, a second torsion bar transmission module movably connected to the second connector 40, and a first gear transmission module disposed between the first torsion bar transmission module and the second torsion bar transmission module. The second transmission unit 27 may include a third torsion bar transmission module movably connected to the first connector 30, a fourth torsion bar transmission module movably connected to the second connector 40, and a second gear transmission module disposed between the third torsion bar transmission module and the fourth torsion bar transmission module. The two ends of the synchronizing rod 24 are respectively connected to the first gear transmission module and the second gear transmission module.

[0086] At this time, assuming the first transmission unit 26 is connected to the electric drive assembly 10, optionally, the first gear transmission module can be connected to the electric drive assembly 10 and rotate under the drive of the electric drive assembly 10. The first gear transmission module can drive at least one of the first torsion bar transmission module and the second torsion bar transmission module connected to it to move, thereby driving the first connecting member 30 connected to the first torsion bar transmission module and / or the second connecting member 40 connected to the second torsion bar transmission module to move. At the same time, the rotation of the first gear transmission module drives the synchronous rod 24 connected to it to rotate, thereby driving the second gear transmission module connected to the other end of the synchronous rod 24 to rotate. The rotation of the second gear transmission module can drive the third torsion bar transmission module and the fourth torsion bar transmission module connected to it to move, thereby driving the first connecting member 30 connected to the third torsion bar transmission module and the second connecting member 40 connected to the fourth torsion bar transmission module to move.

[0087] As an example, at least one of the first gear transmission module and the second gear transmission module can be implemented as at least one gear 23, at least one of the first torsion bar transmission module and the third torsion bar transmission module can be implemented as a first transmission member 21 or a torsion bar portion 202, and at least one of the second torsion bar transmission module and the fourth torsion bar transmission module can be implemented as a second transmission member 22 or a torsion bar portion 202, but the embodiments of this application are not limited thereto.

[0088] In other embodiments, the first transmission unit 26 includes a first torsion bar transmission module connected to the first connector 30 and a second torsion bar transmission module connected to the second connector 40. The second transmission unit 27 may include a third torsion bar transmission module connected to the first connector 30 and a fourth torsion bar transmission module connected to the second connector 40. Here, one or more torsion bar transmission modules may include at least one gear and a torsion bar, such as the gear part 201 and the torsion bar part 202 in the above embodiments, and are connected to the electric drive assembly 10 and / or the synchronizing rod 24 through the gear.

[0089] In some other embodiments, at least one of the first transmission part 26 and the second transmission part 27 may include a torsion bar transmission module 29, which includes at least one gear part 201 and two torsion bar parts 202 disposed on both sides of the at least one gear part 201, or includes at least one gear and two torsion bars connected to the at least one gear, which is not limited here.

[0090] The electric drive assembly 10 can be implemented in various ways. For example, in the above embodiment, the electric drive assembly 10 has only one output terminal, connected to the first transmission unit 26 or the second transmission unit 27, and is used to output power to the first transmission unit 26 or the second transmission unit 27 connected to it. In other embodiments, the electric drive assembly 10 may have two output terminals, respectively connected to the first transmission unit 26 and the second transmission unit 27. In this case, the electric drive assembly 10 may output power to the first transmission unit 26 and the second transmission unit 27 simultaneously, or selectively output power to either the first transmission unit 26 or the second transmission unit 27. Accordingly, the electric drive assembly 10 may include one or more motors 11 and gearboxes 12, which is not limited here. The specific configuration and transmission method of the transmission assembly 20 can also be adaptively adjusted according to different configurations of the electric drive assembly 10, and this application does not limit this.

[0091] In some embodiments, the electric folding device further includes a limiting component 50, which is movably connected to at least one of the first connector 30 and the second connector 40, for limiting the rotation of the first connector 30 and / or the second connector 40.

[0092] In some embodiments, the limiting component 50 includes a limiting bracket 51 and a sliding member 52. The limiting bracket 51 is fixed to the fixed housing 60. The electric drive component 10 and the transmission component 20 are respectively located on both sides of the limiting bracket 51. The limiting bracket 51 is provided with clearance holes, through which the output shaft 13 of the electric drive component 10 passes to connect to the first transmission member 21, and both ends of the synchronizing rod 24 pass through clearance holes to connect to a pair of second transmission members 22. At least one end of the synchronizing rod 24 is provided with a bushing 25, and the bushing 25 is sleeved on the output shaft 13 of the electric drive component 10. The bushing 25 passes through the clearance holes to reduce friction between the output shaft 13, the synchronizing rod 24, and the limiting bracket 51, thereby improving transmission efficiency.

[0093] Please refer to the following at the same time Figures 8 to 10 The limiting bracket 51 is provided with a first limiting part 511, and the first end of the sliding member 52 is provided with a second limiting part 521 that slides and engages with the first limiting part 511. The second end of the sliding member 52 is movably connected to the first connecting member 30 and / or the second connecting member 40. One of the first limiting part 511 and the second limiting part 521 is a sliding wall, and the other is a sliding groove. The sliding wall is engaged in the sliding groove and can slide along the track of the sliding groove.

[0094] Please refer to Figure 11In the example shown, in some embodiments, both the first limiting portion 511 and the second limiting portion 521 are arc-shaped. During the rotation of the slider 52, the second limiting portion 521 slides in contact with the first limiting portion 511. Under the constraint of the first limiting portion 511, the slider 52 rotates around the arc center of the first limiting portion 511.

[0095] In some embodiments, the first connecting member 30 and / or the second connecting member 40 are provided with a third limiting portion 31, and the limiting assembly is provided with a fourth limiting portion 522 that slides with the third limiting portion 31. Optionally, the limiting assembly 50 includes a limiting bracket 51 and a sliding member 52. The sliding member 52 is provided with a fourth limiting portion 522 that slides with the third limiting portion 31. The fourth limiting portion 522 is located at one end of the sliding member 52 away from the second limiting portion 521. One of the third limiting portion 31 and the fourth limiting portion 522 is a sliding wall, and the other is a sliding groove.

[0096] Optionally, both the third limiting part 31 and the fourth limiting part 522 are arc-shaped. During the movement of the electric folding device, the rotation of the first connecting member 30 and / or the second connecting member 40 drives the sliding member 52 to rotate through the cooperation of the third limiting part 31 and the fourth limiting part 522. During the rotation of the sliding member 52, the second limiting part 521 slides in cooperation with the first limiting part 511. Under the restriction of the first limiting part 511, the sliding member 52 and the first connecting member 30 and / or the second connecting member 40 all rotate around the arc center of the first limiting part 511, thereby limiting the first connecting member 30 and / or the second connecting member 40.

[0097] In some embodiments, the limiting assembly 50 further includes a support plate 53. The support plate 53 is fixed to the slider 52 and rotates together with the first connector 30 and / or the second connector 40. Optionally, the support plate 53 is also fixed to the sliders 52 located at both ends of the electric folding device to ensure that the rotation of the first connector 30 and / or the second connector 40 is synchronized.

[0098] When the electric folding device folds, the torsion bar 202 or the torsion bar transmission module 29 drives the first connecting member 30 and the second connecting member 40, which are movably connected to it, to move. The movement of the first connecting member 30 and the second connecting member 40 drives the sliding member 52 to move through the sliding engagement of the third limiting part 31 and the fourth limiting part 522. Through the engagement of the arc-shaped first limiting part 511 and the second limiting part 521, the first connecting member 30 and the second connecting member 40 are ensured to rotate around the arc center of the first limiting part 511. After the first connecting member 30 and the second connecting member 40 rotate 90°, the folding is achieved, making the side shape of the flexible screen 70 of the electronic device approximately teardrop-shaped.

[0099] The electric folding device can achieve the suspension of the first connector 30 and the second connector 40 at any angle under the control of the electronic device's control module. The electric folding device is equipped with a Hall magnet coaxial with the output shaft 13. When the Hall magnet rotates, the magnetic field changes, and the signal of the magnetic field change is transmitted to the control device to accurately identify the rotation angle of the first connector 30 or the second connector 40.

[0100] When the control module inputs a drive signal to the motor 11, the motor 11 rotates, thereby driving the gearbox 12 to rotate and amplify the torque output, which in turn drives the electric folding device to fold and unfold electrically. When the input drive signal stops, it can hover freely. In some embodiments, the electric folding device can also interact with the matrix microphone module of the electronic device via voice, allowing voice control of the folding and unfolding of the electric folding device.

[0101] In some embodiments, such as Figure 12 As shown, the limiting assembly 50 includes a connecting rod 54. A first connecting member 30 and / or a second connecting member 40 are movably connected to at least one connecting rod 54. One end of the connecting rod 54 is connected to the fixed housing 60, and the other end is connected to the first connecting member 30 and / or the second connecting member 40. The connecting rod 54 can be used to limit the first connecting member 30 and / or the second connecting member 40 during their movement.

[0102] This application also provides an electronic device, such as Figure 13 As shown, the device includes a first body 80, a second body 90, and an electrically operated folding device connected to the first body 80 and the second body 90, respectively. The electrically operated folding device may include an electric drive assembly 10, a second connector 40 connected to the first body 80, and a first connector 30 connected to the second body 90, for driving at least one of the first body 80 and the second body 90 to rotate, thereby placing the electronic device in a folded or unfolded state.

[0103] In some embodiments, the electric folding device can be implemented as the electric folding device in any of the above embodiments, and no limitation is made here.

[0104] In some embodiments, the second connector 40 can be fixedly connected to the first body 80 in various ways, and the first connector 30 can be fixedly connected to the second body 90 in various ways. For example, at least one positioning element 33 is provided on the first connector 30 or the second connector 40, and the fixing is achieved by cooperating with at least one adapter on the second body 90 or the first body 80. The positioning element 33 and the adapter can be implemented as a screw hole and a screw, a positioning hole and a positioning hole, etc., and are not limited here.

[0105] In some embodiments, such as Figure 11As shown, the electronic device also includes a flexible screen 70. The flexible screen 70 is fixed to the support plate 53. During the rotation of the first main body 80 and the second main body 90, the flexible screen 70 unfolds or bends with the unfolding or folding of the electric folding device. Optionally, the flexible screen 70 is fixed to the support plate 53 by adhesive.

[0106] In some embodiments, the housing of the first main body 80 forms a first receiving cavity 811, and the housing of the second main body 90 forms a second receiving cavity 821. The two sides of the electrically folding device are respectively housed within the second receiving cavity 821 and the first receiving cavity 811. This makes the electronic device more compact and smaller, saving space and improving portability. Furthermore, by placing the electrically folding device within the internal cavity of the electronic device, the overall appearance of the electronic device becomes more streamlined and concise, enhancing its harmony and aesthetics.

[0107] The second body 90 includes a first surface 8201 (the example in the figure shows the front of the second body 90) and at least one camera 822 disposed on the first surface 8201, enabling the electronic device to perform recording functions such as taking pictures and recording videos. The following description uses one camera 822 as an example, but the number of cameras 822 can also be multiple, and this application embodiment does not limit this.

[0108] The electric folding device can rotate at least one of the second body 90 and the first body 80, causing the first surface 8201 to be exposed or covered. The electric folding device can automatically change the angle or folding angle between the second body 90 and the first body 80, thereby adjusting the shooting angle of the camera 822.

[0109] In some embodiments, the electronic device has an unfolded state, a folded state, and an intermediate state. In the unfolded state, such as... Figure 13 and Figure 14 In the example shown, the angle between the second body 90 and the first body 80 is 180°. In the intermediate state, as... Figure 16 In the example shown, the angle between the second body 90 and the first body 80 is greater than 0° and less than 180°. In the folded state, as... Figure 17 In the example shown, the angle between the second body 90 and the first body 80 is 0°.

[0110] During the transition of the electronic device from an unfolded or intermediate state to a folded state, the first surface 8201 gradually approaches the first body 80. In the folded state, the first surface 8201 is in contact with the first body 80. Thus, the camera 822 located on the first surface is shielded by the first body 80 in the folded state, protecting user privacy through physical shielding and enhancing security. Simultaneously, it effectively prevents physical collisions and scratches to the camera 822, reducing the possibility of damage to the electronic device and extending its lifespan. Furthermore, in the folded state, the electronic device has a compact structure, making it easy to carry and store.

[0111] The electronic device in this application embodiment is driven by an electric folding device, which enables the second main body 90 to rotate automatically relative to the first main body 80. The angle between the two varies from 0° to 180°, thereby realizing the conversion between different states, improving the shooting effect of the camera 822, and can be flexibly applied in different scenarios to meet the diverse needs of users.

[0112] In some embodiments, the electric folding device can drive the second main body 90 to rotate while the first main body 80 remains stationary. In this case, the angle range of the rotation of the second main body 90 driven by the electric folding device can be from 0° to 180°. In other embodiments, the electric folding device can drive the first main body 80 to rotate while the second main body 90 remains stationary. In still other embodiments, the electric folding device can drive the first main body 80 and the second main body 90 to rotate synchronously. For example, the second main body 90 and the first main body 80 rotate synchronously in opposite directions, wherein the rotation angles of the first main body 80 and the second main body 90 during synchronous rotation can be the same or different, thereby improving transmission efficiency and making the change of shooting angle more flexible.

[0113] In some embodiments, the electronic device of this application further includes a control module (not shown in the figures) for controlling the rotation angle of the second body 90 and / or the first body 80. The control module can achieve autonomous rotation shooting recognition based on information collected by the camera 822. The control module can be implemented as a software-based control module or a hardware-based control module, such as a microcontroller, microprocessor, programmable logic circuit, application-specific integrated circuit, control circuit, etc. The control module can control the rotation angle of the second body 90 and / or the first body 80 based on one or more types of information.

[0114] In some embodiments, the control module can determine the rotation angle of the second main body 90 and / or the first main body 80, or determine the target angle between the second main body 90 and the first main body 80, based on the image information captured by the camera 822, and then control the electric folding device to rotate the second main body 90 and / or the first main body 80. For example, the image captured by the camera 822 can be processed to obtain an image recognition result, and the target angle between the second main body 90 and the first main body 80 can be determined based on the image recognition result. The image recognition result may include whether a target object or a specific type of object is included, whether the included object is complete, the current shooting scene, etc.

[0115] In some embodiments, the electronic device further includes an angle detection module (not shown) for detecting the angle of the second body 90 or the first body 80 relative to the electrically folding device. This angle detection module can be a Hall sensor or other components. Optionally, the control module can also determine the rotation angle of the second body 90 and / or the first body 80 based on the detection result of the angle detection module. For example, the control module can control the electrically folding device to rotate the second body 90 and / or the first body 80 based on the difference between the current angle and the target angle between the second body 90 and the first body 80. The target angle can be determined according to user instructions, the current shooting scene, or image information captured by the camera 822, etc., and is not limited here. In this way, the rotation of the second body 90 and / or the first body 80 can be controlled by the control module to adjust the shooting angle of the camera 822, thereby achieving the best shooting or recognition effect.

[0116] In some embodiments, the electronic device can be used for user activity recording or for assisting health management. When the control module detects food in the image captured by the camera 822, it can determine and record the calories of the detected food, thereby providing users with health information such as food intake calorie and / or nutritional analysis.

[0117] In some embodiments, the electronic device may include a microprocessor for performing at least a portion of the above-described image processing, angle recognition, and other processing procedures. For example, the microprocessor may identify images captured by the camera 822 to determine whether the image contains food, or whether the objects in the image are complete, etc. As another example, the microprocessor may process signals acquired by the angle detection module to obtain the current angle between the second subject 90 and the first subject 80. As yet another example, the microprocessor may perform instruction recognition processing on user operations received by the electronic device to obtain the user instructions corresponding to the user operations. And so on; the functionality of the microprocessor is not limited here.

[0118] In some embodiments, the electronic device of this application may further include a wireless communication module for communicating with other electronic devices. For example, it may interact with smart terminal devices such as mobile phones or servers. In this case, any processing involved in the embodiments of this application may be completed by a microprocessor and other electronic devices in cooperation, or by other electronic devices alone. As an example, the electronic device may transmit image information captured by the camera 822 to a terminal device or server through the wireless communication module. The terminal device or server may process the received image information to obtain image recognition results, or further obtain food calories.

[0119] As another example, electronic devices can transmit food intake information (such as food images, food recognition results, food calories, or at least one of these) to terminal devices or servers. Based on the user's food intake information, the terminal devices or servers can obtain a summary or suggestion of the user's food intake over a certain period of time. For example, whether the user's daily calorie intake exceeds the reference or expected value, or whether the user's food intake over a day or week meets the reference nutritional standards, etc.

[0120] In some embodiments, the terminal device or server can also acquire the user's exercise data and, based on the user's exercise data and food intake data, obtain the user's health results or suggestions within a specific time period. For example, it can obtain the difference between the user's food calorie intake and exercise calorie expenditure in a day, and determine whether the difference meets the user's health goals or reference standards. Another example is obtaining the user's already consumed food calories in a day, and, based on the difference between the already consumed food calories and the daily food calorie intake target, obtaining the food calorie intake that can be consumed for the remaining time of the day. Yet another example is comparing the calories of currently captured food with the corresponding food calorie target to determine whether the currently captured food meets the calorie control target, or, if it is determined that the currently captured food exceeds the calorie control target, providing the user with exercise suggestions to consume that excess calorie value, and so on.

[0121] In other embodiments, by cooperating with a smart terminal device or server, the electronic device can provide users with at least one of the following based on their attribute information, health goals, dietary habits, historical dietary data, exercise habits, and historical exercise data: nutritional references, dietary suggestions, exercise suggestions, a diet plan for a certain period of time, and a workout plan for a certain period of time. Thus, the electronic device of this application can cooperate with other electronic devices to provide suggestions for the user's dietary health, becoming the user's personal health assistant.

[0122] In some embodiments, the electronic device of this application further includes a folding control component 812. The folding control component 812 is disposed on the side of the housing of the first main body 80 and is used to receive a user's folding control command. The folding control command is used to control the electronic device to switch to a folded state. The folding control component 812 can be implemented in various ways. In some embodiments, the folding control component 812 can be a button, a knob, a touch-sensitive component, or other interactive components. In other embodiments, the folding control component 812 can include a slot and a torsion member disposed within the slot. The user can issue a folding control command or an unfolding control command by changing the position of the torsion member within the slot, for example, by tossing the torsion member. In other embodiments, the user can also issue a folding control command or an unfolding control command through voice, specific gestures, or specific actions, etc., which is not limited here.

[0123] Thus, in some embodiments, when the electronic device is in an unfolded state or an intermediate state, the user can issue a folding control command by operating the folding control component 812. The folding control component 812 can respond to the folding control command and control the electric folding device to drive the second body 90 and / or the first body 80 to rotate to the folded state, thereby realizing a one-click conversion of the electronic device to the folded state.

[0124] In other embodiments, when the electronic device is in a folded or intermediate state, the user can issue an unfolding control command by operating the folding control component 812. The folding control component 812 can respond to the unfolding control command by controlling the electric folding device to rotate the second main body 90 and / or the first main body 80, thereby switching the electronic device to the unfolded state, achieving a one-click switch to the unfolded state. In some embodiments, the camera 822 can be automatically activated in response to the electronic device switching to the unfolded state, but this is not limited to this.

[0125] As can be seen, on the one hand, the electronic device in this application embodiment can automatically switch between different states with the cooperation of devices such as camera 822 and control module. On the other hand, the electronic device can manually switch between different states through folding control component 812, so that the electronic device can flexibly respond to different scenarios, improve usage efficiency, and enhance interactive experience.

[0126] Please refer to Figure 15In some embodiments, the housing of the first body 80 includes a first region 8101 and a second region 8102, wherein the thickness of the second region 8102 is greater than the thickness of the first region 8101. The first region 8101 is located close to the second body 90, at the upper part of the first body 80, while the second region 8102 is located away from the second body 90, at the lower part of the first body 80. In some examples, the first region 8101 and the second region 8102 may be distributed along the length of the first surface of the main body housing and both occupy the entire width of the first surface of the main body housing, but this embodiment is not limited in this respect. Optionally, the first region 8101 can be connected to the second body 90 via an electric folding device. The second region 8102 and the second body 90 are located on opposite sides of the first region 8101.

[0127] When the electronic device is folded, the second main body 90 can overlap at least a portion of the first region 8101, causing the camera 822 to be obscured by the first region 8101. This allows for a relatively small thickness in the first region 8101, providing space for the placement of the second main body 90 when the device is folded, thus reducing the overall thickness of the electronic device in this state. Simultaneously, the relatively large thickness of the second region 8102 provides more space for internal electronic components, facilitating miniaturization and a thinner, lighter design.

[0128] In some embodiments, the cross-sectional area of ​​the first region 8101 may be larger than the cross-sectional area of ​​the second region 8102, thereby facilitating better accommodation of the second body 90 and improving the visual thinness of the electronic device. In some examples, the cross-sectional area of ​​the first region 8101 may be much larger than the cross-sectional area of ​​the second region 8102, for example, the cross-sectional area of ​​the first region 8101 may be 2 times, 2.5 times, 3 times or more than that of the second region 8102, and this is not limited here.

[0129] Please refer to Figure 17 In some embodiments, in the folded state, the total thickness of the second body 90 and the first region 8101 stacked together is the same as or similar to the thickness of the second region 8102, making the appearance of the electronic device smoother and more streamlined even in the folded state. In some embodiments, the thickness of the first region 8101 is the same as or similar to the thickness of the second body 90, which is not limited here. Furthermore, in some embodiments, the cross-sectional area of ​​the first region 8101 may be equal to or slightly larger than the cross-sectional area of ​​the first surface of the second body 90 to improve the visual integrity of the device in the folded state.

[0130] In some embodiments, one or more electronic devices may be disposed inside the housing of the second region 8102. Please refer to... Figure 18The electronic device also includes a speaker unit 813 disposed within the second region 8102. The speaker unit 813 includes a speaker housing 8131, a sound-generating component 8132, a sound-emitting port 8133, a circuit board 8134, and a diaphragm 8135.

[0131] The speaker housing 8131 may include a front speaker housing 1311 and a rear speaker housing 1312. Both the front speaker housing 1311 and the rear speaker housing 1312 may be made of plastic material and are fixedly connected, providing a acoustic cavity volume for the sound-generating assembly 8132. The speaker unit 813 can be fixed within the main body housing via the speaker housing 8131. As an example, at least one of the front speaker housing 1311 and the rear speaker housing 1312 is fixed to the housing of the first main body 80 by bolts.

[0132] One or more sound-emitting holes 8133 are formed on the speaker housing 8131. In some embodiments, multiple sound-emitting holes 8133 are formed on the speaker housing 8131, and the total area of ​​the multiple sound-emitting holes 8133 is greater than a certain value, for example, greater than 25 square millimeters, to improve the performance of the speaker unit 813. Figure 18 In the example shown, the speaker holes 8133 are opened on the front housing 1311 of the speaker, and there are two of them, but this application embodiment does not limit this.

[0133] In addition, such as Figure 18 As shown, a balance diaphragm 8135 is also provided on the speaker housing 8131 to maintain the air pressure balance inside and outside the speaker housing 8131, prevent sound distortion, and thus provide a better listening experience.

[0134] The sound-generating component 8132 is disposed on a circuit board 8134 inside the speaker housing 8131. In some embodiments, the circuit board 8134 may be a flexible printed circuit (FPC), but this is not a limitation.

[0135] In this way, by setting an independent speaker unit 813 within the first main body 80, better sound output can be provided to meet the user's needs for audio interaction.

[0136] In some embodiments, a second region 8102 of the housing of the first body 80 is provided with a sound outlet array 1021 to allow sound emitted by the speaker unit 813 to exit the housing. Optionally, the coverage area of ​​the sound outlet array 1021 may be greater than at least one speaker hole 8133 to improve sound output. Figure 19 In the example shown, the sound hole array 1021 can be set on the first surface of the housing of the first body 80, that is, the front shell of the first body 80, and basically cover most or the entire area of ​​the first surface, but this is not limited here.

[0137] Please refer to the following at the same time Figure 19 and Figure 20 In some embodiments, the second region 8102 of the housing of the first main body 80 is further provided with a keypad 814. The keypad 814 includes a first sub-region 8141 and a second sub-region 8142. The first sub-region 8141 forms a first button 8143, and the second sub-region 8142 forms a second button 8144, so that the user can realize human-computer interaction by pressing the buttons. Optionally, the sound hole array 1021 can be disposed on the keypad 814. In this way, the keypad 814 can realize both sound output function and interaction function, which can reduce the hardware cost of the device and reduce the thickness of the device.

[0138] In some examples, the first sub-region 8141 and the second sub-region 8142 can occupy most or the entire cross-section of the keypad 814 to increase the operating area of ​​the key control and improve the user's key feel.

[0139] The first button 8143 and the second button 8144 can be implemented in various ways. In some embodiments, the second region 8102 of the housing of the first body 80 further includes a fixing shaft 8145. One side of the fixing shaft 8145 is fixed to the housing of the first body 80, and the other side is connected to the button plate 814. Figure 19 In the example shown, an elastic element 8146 is sleeved on the fixed shaft 8145, and the keypad 814 abuts against the elastic element 8146, but this is not limited here.

[0140] The button panel 814 can be divided into a first sub-region 8141 and a second sub-region 8142 with a fixed axis 8145 as the boundary, and can rotate around the fixed axis 8145, so that when one of the first button 8143 and the second button 8144 is pressed, the other button is lifted, thereby realizing a seesaw-type button. In some embodiments, the first button 8143 and the second button 8144 are provided with pressing protrusions to provide good tactile feedback and improve button recognition.

[0141] In some embodiments, a press detection module is provided inside the housing of the first main body 80.

The at least two button levers 8147 can be respectively disposed corresponding to the first sub-region 8141 and the second sub-region 8142. When the user does not press the button panel 814, the at least two button levers 8147 are in a free state, with their ends respectively close to and spaced apart from the button panel 814 and the membrane key 8148, or in contact with the button panel 814 and the membrane key 8148 without any interaction force. When the user presses the first button 8143 or the second button 8144, the first button 8143 or the second button 8144 is pressed down and comes into contact with the button lever 8147 in the corresponding area. The button lever 8147 in the corresponding area is pressed down and moves down to come into contact with the membrane button 8148. The sensor can detect the press by detecting the force or other parameters applied to the membrane button 8148.

[0142] In some embodiments, the housing of the first body 80 has at least one opening at a position corresponding to the first sub-region 8141 and the second sub-region 8142, respectively. One end of the button lever 8147 is disposed inside the housing of the first body 80, and the other end extends out of the housing from the opening. Furthermore, the button lever 8147 can be movably connected to the housing of the first body 80. In one example, the button lever 8147 has at least one limiting groove, and at least one limiting post is disposed inside the housing of the first body 80. One end of the limiting post is fixed inside the housing of the first body 80, and the other end is disposed in the limiting groove and can move up and down within the limiting groove. The embodiments of this application do not limit the implementation and fixing method of the button lever 8147.

[0143] In some embodiments, at least one matrix microphone module 815 is also provided on the side of the electronic device for receiving user voice input.

Optionally, the electronic device of this embodiment can transmit the voice input to other electronic devices, such as terminal devices or servers, through a wireless communication module, so that the other electronic devices can recognize the voice input and return a voice recognition result. Accordingly, the electronic device can respond based on the received voice recognition result, or the terminal device or server can return a response to the voice recognition result. At this time, the electronic device can output the response to the user, such as displaying corresponding content on the display screen, etc. In this way, the matrix microphone module 815 can cooperate with the speaker unit 813 to realize voice interaction. In some embodiments, there are multiple matrix microphone modules 815, which are distributed on the same side of the housing of the first main body 80, but the embodiments of this application are not limited to this.

[0144] Please refer to Figure 14 and Figure 17 The electronic device in this embodiment of the application is further provided with a display screen 823 for displaying images captured by the camera 822, or outputting responses to user input, or outputting content sent by other electronic devices to the user, which is not limited here. In some embodiments, the display screen 823 may be disposed on the second surface 8202 of the second body 90 opposite to the first surface 8201 (the example in the figure is the back of the second body 90). In some embodiments, the display screen 823 may be a touch screen, but this is not limited here.

[0145] In some embodiments, the first surface 8201 of the second body 90 is further provided with at least one light strip module 824, which can be used to emit prompts, provide supplementary lighting, or function as an ambient light. For example, it can indicate the current battery level of the electronic device, indicate low battery status, provide call reminders, message reminders, or task reminders. Furthermore, the light strip module 824 can provide supplementary lighting in dark or low-light environments, thereby meeting the user's shooting needs in such conditions. Additionally, the light strip module 824 can be used as an ambient light to enhance the technological feel of the device.

[0146] In some examples, the electronic device can automatically control the lighting or extinguishing of the LED strip module 824. For instance, if the electronic device determines that the brightness of the image captured by the camera 822 is below a certain threshold, it will control at least a portion of the LED strip module 824 to light up. In other examples, the user can issue LED strip control commands to control the lighting or extinguishing of the LED strip module 824, or further control the display brightness of the LED strip module 824. The user can issue LED strip control commands through the display screen 823, the first button 8143, the second button 8144, or other means; this is not limited to these methods. Optionally, the surface of the LED strip module 824 is covered with a PCI film, which can effectively prevent physical damage or chemical corrosion from external factors, thereby improving the durability of the LED strip module 824.

[0147] In some embodiments, the electronic device further includes at least one of a microprocessor, a memory, and a gyroscope. The memory can be used to store various types of data to support the operation of the electronic device, such as caching image data captured by the camera 822. The microprocessor can be used to perform various operations of the electronic device, such as recognizing user input commands and rotation angles. The gyroscope is used to provide good image stabilization, ensuring that the video footage captured by the electronic device is stable and clear in various usage scenarios.

[0148] In some embodiments, the gyroscope is a six-axis gyroscope, which is mounted on a motherboard inside the second body 90. When the electronic device is in motion or when the second body 90 rotates relative to the first body 80, the gyroscope enables the camera 822 to achieve image stabilization.

[0149] The electronic device in this application embodiment provides multiple image stabilization levels for the user to choose from. The user can manually switch the image stabilization options during shooting according to different usage scenarios and needs. In one example, information related to multiple image stabilization options is output to the user through a display screen 823, a speaker unit 813, or other output components for the user to select and switch. The electronic device may output information related to multiple image stabilization options when it determines that the quality of the currently captured image does not meet expectations or when it determines that the shooting environment or scene has changed, or it may output information related to multiple image stabilization options upon receiving a viewing command from the user, etc., etc., without limitation.

[0150] In some embodiments, the electronic device may also determine at least one of the user's motion state and the usage scenario, and automatically adjust the image stabilization parameters based on at least one of the motion state and the usage scenario to achieve the best shooting effect. For example, it may automatically increase the image stabilization intensity in scenarios where the user is moving vigorously, and automatically decrease the image stabilization intensity in scenarios where the user is stationary or moving gently; this is not limited to these specific scenarios.

[0151] In some embodiments, electronic devices can embed gyroscope data into the captured video file by default, or can convert gyroscope data into CSV or JSON format files to support users in performing offline image stabilization on the video after shooting.

[0152] In some embodiments, the electronic device further includes at least one sensor, such as one or more physiological parameter sensors, environmental sensors, motion sensors, etc.

[0153] In other embodiments, to reduce device hardware costs and achieve miniaturization of the electronic device, the electronic device may not have internal sensors, but instead acquire sensor data by connecting to an external multifunctional device. Accordingly, this application also provides a multifunctional device including at least one sensor, to which the electronic device can connect and acquire sensor data. The at least one sensor included in the multifunctional device may include at least one of a physiological parameter sensor, a motion sensor, and an environmental sensor.

[0154] In some embodiments, the multifunctional device may include multiple environmental sensors, such as at least one of a gas sensor (e.g., a carbon dioxide sensor, a carbon monoxide sensor, a harmful gas sensor, etc.), an ultraviolet (UV) sensor, a PM2.5 sensor, an infrared sensor, an ambient temperature sensor, an ambient humidity sensor, an ambient brightness sensor, a positioning sensor, and a barometric pressure sensor.

[0155] In some embodiments, the multifunctional device may include a housing and a circuit board disposed within the housing, with multiple environmental sensors disposed on the circuit board. In some embodiments, at least one venting groove may be provided on the housing of the multifunctional device to enable sensor data acquisition by the environmental sensors.

[0156] In some embodiments, the multifunctional device may further include a battery unit and a charging unit, or further include a microcontroller unit and a memory. In some embodiments, the multifunctional device may contain as few electronic components as possible to facilitate its miniaturization design. For example, the multifunctional device may omit human-computer interaction components such as a display screen and a speaker, but this is not a limitation.

[0157] In some embodiments, multiple environmental sensors may be disposed on the same circuit board, such as on the same side or different sides of the same circuit board. Multiple environmental sensors and other electronic components, such as battery cells, may be disposed on the same or different circuit boards. As an example, multiple environmental sensors and at least one other electronic component may be disposed on the same circuit board, wherein the multiple environmental sensors are disposed on a first surface of the circuit board, and at least one other electronic component is disposed on a second surface of the circuit board opposite to the first surface, in order to minimize device space and achieve miniaturized design of a multifunctional device.

[0158] In some embodiments, the multifunctional device may include a connecting portion, through which it can be detachably connected to the first body 80. As an example, the connecting portion may include a first magnetic element and / or a positioning element, and correspondingly, a second magnetic element and / or a positioning adapter is provided on the bottom of the main unit. Thus, the multifunctional device and the first body 80 can be magnetically connected via the first and second magnetic elements. Alternatively, the multifunctional device can be detachably connected to the first body 80 via a positioning element and a positioning adapter, wherein the positioning element can be implemented as, for example, a snap-fit, and the positioning adapter can be implemented as, for example, a slot, etc., without limitation.

[0159] In some embodiments, the multifunctional device may be provided with a charging interface for connecting to an external power source.

[0160] In some embodiments, the connection portion may further include at least one first charging terminal for connecting to at least one second charging terminal at the bottom of the first body 80 and for providing power to the first body 80 or receiving power provided by the first body 80.

[0161] In some embodiments, when the multifunctional device is connected to the first body 80 and an external power source respectively, power supplied by the external power source can be transmitted to the first body 80.

[0162] In some embodiments, when the multifunctional device is not connected to an external power source, it can transmit power from its battery cell to the first body 80, or it can receive power transmitted from the first body 80.

[0163] In some embodiments, the connection portion may further include at least one first data transmission terminal, such as a serial port terminal, for interacting with an electronic device and / or transmitting data with the electronic device when connected to a second data transmission terminal at the bottom of the first body 80.

[0164] In some embodiments, the multi-functional device is provided with at least one first USB terminal for data transfer with electronic devices when connected to a second USB terminal on the bottom of the host. In some embodiments, the multi-functional device can also be connected to other electronic devices (such as computers) via the first USB terminal to achieve data transfer with other electronic devices. The first USB terminal and the charging terminal may be located on the same side or different sides of the multi-functional device, or they may share the same terminal.

[0165] In some embodiments, the multifunctional device does not have a wireless communication module. In this case, when the multifunctional device is physically connected to the first main body 80, the multifunctional device can transmit sensor data detected by at least one sensor to an electronic device. The microprocessor of the electronic device can process the received sensor data to obtain a detection result. Alternatively, the electronic device can transmit the received sensor data directly or after processing to other electronic devices, where the sensor data is processed and a detection result is obtained, or the detection result is presented to the user by other electronic devices. In other embodiments, the multifunctional device can process the sensor data to obtain a detection result, and then transmit the detection result to an electronic device, which provides the detection result to the user or performs an alarm or reminder. Alternatively, the electronic device can further transmit the data to other electronic devices for alarm or reminder processing.

[0166] In some embodiments, the shooting parameters of the camera 822 and / or the angle of the second subject 90 can be adjusted based on environmental data collected by the environmental sensor. For example, when the UV sensor detects strong ultraviolet radiation, the control module can control the camera 822 to activate the UV protection filter or adjust the image color to avoid overexposure or damage to the device, etc.

[0167] In some embodiments, the user's current scene can be determined based on environmental data collected by environmental sensors, and the target object to be captured by the camera can be determined based on that scene. For example, if the user is determined to be dining in a restaurant based on the environmental data collected by the environmental sensors, then the target object to be captured by the camera is determined to be food, and the angle of the second body 90 and / or the camera 822 is controlled so that the image captured by the camera 822 includes food.

[0168] In some embodiments, the state of other electronic components and / or the electronic device can be controlled based on environmental data collected by an environmental sensor. For example, when the ambient brightness data collected by an ambient brightness sensor determines that the current ambient brightness is low, such as below a certain threshold, at least a portion of at least one light strip module 824 can be activated, or the brightness of the activated light strip module 824 can be further controlled, or the flash of the camera 822 can be turned on. As another example, when the ambient brightness data collected by the ambient brightness sensor indicates that the current ambient brightness does not meet preset or current shooting conditions, and / or the PM2.5 data collected by the PM2.5 sensor indicates that the current PM2.5 concentration in the air does not meet preset or current shooting conditions, the electronic device can be controlled to switch from an unfolded state to a folded state.

[0169] In other embodiments, environmental data collected by environmental sensors can be used as image capture annotation data synchronously captured by camera 822 to form a video log. Users can view the video log to understand the environmental information during shooting. In other embodiments, the environmental data collected by environmental sensors and the image data synchronously captured by camera 822 can be sent to a terminal device or server so that the terminal device or server can process the image data based on the environmental data.

[0170] In some embodiments, user health monitoring can be performed, at least in part, based on environmental data collected by environmental sensors, and / or alerts can be issued to the user when an abnormal environment is detected or specific alert conditions are met. For example, the user may be alerted when the ambient temperature is detected to be too high or too low; or when the ambient humidity is detected to be too high or too low, the user may be alerted to turn on a humidifier or dehumidifier; or when a high concentration of harmful gases is detected (e.g., exceeding a specific threshold), the user may be alerted to evacuate, turn on an air purifier, or close windows to protect their health. For example, when a high PM2.5 concentration is detected or reaches a specific air pollution standard, the user may be alerted to wear a mask, etc. For example, when an infrared sensor detects that the local ambient temperature is too high or a hot object is rapidly approaching the user (e.g., the temperature exceeds a specific threshold and / or the speed at which the object approaches the user exceeds a specific threshold), the user may be alerted to immediately move away to avoid being burned.

[0171] In some embodiments, the method of alerting the user can also be determined at least in part based on environmental data collected by environmental sensors. For example, if the environmental data collected by the environmental sensors determines that the user is currently in a noisy environment with high noise levels, a prompt message can be output through the display screen. As another example, if the environmental data collected by the environmental sensors determines that the user is currently in an environment with high ultraviolet radiation concentration, a prompt message can be output through voice. Yet another example, if the environmental data collected by the environmental sensors and image data captured by a camera determine that the user may be in danger, a reminder message can be sent to a preset device or preset number, and so on.

[0172] In some embodiments, sleep quality analysis and / or sleep recommendations can be performed, at least in part, based on environmental data collected by environmental sensors. For example, sleep environment parameters (such as sleep light, carbon dioxide concentration, temperature, humidity, noise, etc.) can be detected by environmental sensors, and combined with sleep monitoring data obtained from motion sensors and / or physiological parameter sensors, to perform sleep quality analysis, obtain the user's sleep quality, or further obtain environmental parameters that affect the user's sleep quality, and provide the user with targeted sleep recommendations.

[0173] In other embodiments, the multifunctional device or electronic device may also include one or more motion sensors, such as accelerometers, gyroscopes, geomagnetic sensors, etc., for collecting motion data of the multifunctional device or electronic device.

[0174] In some embodiments, the electronic device can interact with other electronic devices (such as wrist-worn devices, ring devices, earphone devices, head-mounted devices, etc.). For example, the electronic device can acquire one or more health data, such as motion data, sleep data, and physiological parameter measurement data, from other electronic devices via a wireless communication module, or acquire environmental data from a physically connected multifunctional device, and combine it with at least one of the health data, environmental data, and image data to obtain the user's personal health data. Optionally, the electronic device can also present the obtained personal health data to the user, for example, by displaying it on the screen 823, or by providing the user with health advice or health reminders. In other embodiments, the electronic device can also send the image data captured by the camera 822 and / or the environmental data captured by the environmental sensor to other electronic devices for analysis and processing.

[0177] In some embodiments, a charging port 842 may be provided on one side of the charging base 840 for connecting to an external power source. Thus, when the charging base 840 is connected to both the first main body 80 and an external power source, power supplied by the external power source can be transmitted to the first main body 80. In some embodiments, the charging base 840 may include a power module or a battery storage module. When the charging base 840 is not connected to an external power source, power from the power module or battery storage module can be transmitted to the first main body 80; this is not limited to any particular embodiment.

[0178] In this way, by setting the charging circuit in the charging base 840 and setting the charging base 840 to be detachably connected to the first body 80, it is possible to reduce the weight and size of the first body 80 and the second body 90 while providing charging convenience.

[0179] Please refer to Figure 14 As shown, in some embodiments, the electronic device may further include a fixing member 850, which is detachably connected to the first body 80. The fixing member 850 may be detachably connected to the first body 80 via magnetic attraction, clamping, snap-fit, or other means, which are not limited here. As an example, the fixing member 850 may be detachably disposed on the back of the first body 80, facilitating the user to fix the electronic device, for example, to items such as the chest, mobile phone, helmet, bicycle, or handheld pole, to better adapt to different application scenarios. In some embodiments, the fixing member 850 includes a clamping plate with at least one through hole 851 for engaging with a strap, so as to fix the electronic device to the human body via the strap.

[0180] In some embodiments, the length of the electronic device in the unfolded state is 80mm-120mm (along...). Figure 13 (as shown in the vertical direction), width is 30mm-60mm (along...) Figure 13(as shown in the left-right direction), the thickness of the second main body 90 is 8mm-12mm (along the left-right direction). Figure 13 (As shown in the front-back direction), the thickness of the upper part of the first main body 80 is 8mm-12mm, and the thickness of the lower part is 16mm-24mm. It is small, lightweight, and easy to carry.

[0181] The thickness of the electric folding device is less than the thickness of the second body 90. In some embodiments, the thickness of the second body 90 is about 10 mm, and the thickness of the electric folding device is less than 8 mm, but this is not a limitation.

[0182] The electric folding device and electronic device of this application, by setting an electric drive component 10, and causing the electric drive component 10 to drive at least one of the first connector 30 and the second connector 40 to rotate through the transmission component 20, can automatically complete the unfolding or folding of the electric folding device, avoiding frequent manual adjustments by the user, improving ease of use, and saving effort and increasing efficiency.
