Description

Technical Field

[0001] This invention relates to the field of mechanical technology, and in particular to a synchronization mechanism and terminal equipment. Background Technology

[0002] With the advancement of technology, mobile phones have become increasingly diverse, and foldable phones are a new type of mobile phone. Foldable phones generally consist of two sets of shells, and the two sets of shells can be folded and rotated synchronously by a mechanism.

[0003] However, traditional synchronization mechanisms still have some drawbacks in use. For example, most traditional synchronization mechanisms cannot be fully placed in limited spaces, affecting the overall thickness of the machine. Furthermore, some synchronization mechanisms have complex structures and high manufacturing costs, leading to an increase in the overall cost of the machine. Summary of the Invention

[0004] In view of the above problems, embodiments of the present invention are proposed to provide a synchronization mechanism and terminal device that solve the above problems.

[0005] In one embodiment of the present invention, a synchronization mechanism is provided, comprising:

[0006] support;

[0007] A synchronization slider is disposed on one side of the bracket, the synchronization slider is movably connected to the bracket, and can move relative to the bracket along a first direction;

[0008] Two swinging components are located on opposite sides of the synchronous slider and are rotatably connected to the bracket and drively connected to the synchronous slider, respectively.

[0009] When one of the swinging components rotates relative to the bracket, it synchronously drives the synchronous slider to move along the first direction, so as to drive the other swinging component to rotate synchronously relative to the bracket in the opposite direction.

[0010] In some embodiments, the two swing members are rotatably connected to the two rotation axes of the bracket, which are parallel to each other, and the first direction is perpendicular to the plane containing the two rotation axes.

[0013] In some embodiments, one of the first limiting structure and the second limiting structure is a groove structure, and the other is a protrusion structure used in conjunction with the groove structure.

[0014] In some embodiments, one of the bracket and the swing member is provided with a first rotating shaft, and the other is provided with a first shaft hole for use with the first rotating shaft, wherein the first rotating shaft and the first shaft hole are rotatably connected; or

[0015] Both the bracket and the swing member are provided with a second shaft hole. A second rotating shaft passes through the second shaft hole on the bracket and the swing member to realize the rotatable connection between the swing member and the bracket.

[0016] In some embodiments, the synchronous slider is provided with a first hinge structure at each of the opposite ends corresponding to the swing member, and the swing member is provided with a second hinge structure at the position corresponding to the first hinge structure, and the first hinge structure and the second hinge structure are movably hinged together.

[0017] When one of the swinging components rotates relative to the bracket, the swinging component drives the synchronizing slider to move relative to the bracket in the first direction through the second hinge structure, so as to drive the other swinging component to rotate synchronously through the synchronizing slider.

[0018] In some embodiments, the first hinge structure is a hinge slot or a hinge hole, and the second hinge structure is a moving block used in conjunction with the hinge slot or the hinge hole;

[0019] The moving block can move relative to the hinge slot or the hinge hole along a second direction, which is perpendicular to the first direction.

[0020] In some embodiments, one end of the swing member is provided with an adapter ring, and the swing member is rotatably connected to the bracket through the adapter ring;

[0021] The moving block is disposed on the axial end face of the adapter ring on the side facing the synchronous slider. When the swing member rotates relative to the bracket, it drives the moving block to move circumferentially along the adapter ring through the adapter ring. At the same time, the moving block moves relative to the synchronous slider along the second direction, so as to drive the synchronous slider to move along the first direction.

[0049] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Unless otherwise defined, all technical and scientific terms used in the embodiments of the present invention have the same meaning as commonly understood by those skilled in the art. The terminology used in the specification of the embodiments of the present invention is for the purpose of describing specific embodiments only and is not intended to limit the embodiments of the present invention.

[0050] Figure 1 This is a schematic diagram of a synchronization mechanism provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of a planar structure of a synchronization mechanism provided in an embodiment of the present invention, as shown below. Figure 1 and Figure 2 As shown.

[0051] In one embodiment of the present invention, a synchronization mechanism is provided, comprising: a support 10, a synchronization slider 20, and two swing members 30. The synchronization slider 20 is disposed on one side of the support 10, movably connected to the support 10, and movable relative to the support 10 along a first direction. The two swing members 30 are respectively located on opposite sides of the synchronization slider 20, rotatably connected to the support 10, and drively connected to the synchronization slider 20. When one swing member 30 rotates relative to the support 10, it synchronously drives the synchronization slider 20 to move along the first direction, thereby causing the other swing member 30 to rotate synchronously relative to the support 10 in the opposite direction.

[0052] For example, see Figure 1 and Figure 2 In one feasible embodiment, the synchronization mechanism includes a support 10, a synchronization slider 20, and two oscillating members 30, namely oscillating member 30a and oscillating member 30b. The support 10 provides support for the oscillating members 30 and the synchronization slider 20. One end of each of the two oscillating members 30 is rotatably connected to the support 10 and is drively connected to the synchronization slider 20. The synchronization slider 20 can move relative to the support 10 along a first direction. One implementation of the first direction is as follows: Figure 1 and Figure 2 Taking the orientation as an example, the synchronous slider 20 can move up and down relative to the support 10 along the thickness direction of the support 10, which is the first direction. Or, Figure 2 The direction of the extension of the Y-axis in the diagram is the first direction. Alternatively, as... Figure 1As shown, the two swinging members 30 are rotatably connected to the bracket 10 via two parallel axes of rotation, which are respectively... Figure 1 The rotation axes L1 and L2, shown by the dashed lines, have their first direction perpendicular to the plane containing the two rotation axes.

[0053] by Figure 1 and Figure 2 Taking the orientation as an example, when the swing element 30a rotates clockwise relative to the support 10, as the swing element 30a rotates, it will drive the synchronous slider 20 to move downward. When the synchronous slider 20 moves downward, it will drive the swing element 30b to rotate counterclockwise relative to the support 10. At this time, the swing elements 30a and 30b rotate in opposite directions, which are... Figure 2 As indicated by the solid arrow, the ends of the swing members 30a and 30b furthest from the transition position move closer to each other. The movement of the synchronized slider 20 and the counter-clockwise rotation of the swing member 30b are synchronized with the clockwise rotation of the swing member 30a. Therefore, the synchronized rotation of the two swing members 30 is achieved, and the rotation directions of the swing members 30a and 30b are opposite, thus achieving the synchronized folding action of the two swing members 30. When the swing members 30a and 30b stop rotating towards each other, their positions are the first stop positions. When the swing members 30a and 30b are in the first stop positions, they stop rotating, and at this time, the swing members 30a and 30b are in a folded state.

[0054] When the swing element 30a rotates counterclockwise relative to the bracket 10, the swing element 30a can synchronously drive the swing element 30b to rotate clockwise via the synchronous slider 20. At this time, the swing elements 30a and 30b rotate in opposite directions, which are... Figure 2 As indicated by the dashed arrow, the ends of swing members 30a and 30b furthest from the transition position move away from each other, thus achieving synchronous deployment of the two swing members 30. When swing members 30a and 30b stop rotating in opposite directions, their positions are the second stop positions. When swing members 30a and 30b are in the second stop positions, they stop rotating and are in an deployed state.

[0055] Of course, it should be noted that in some feasible embodiments, when the swing member 30a rotates clockwise relative to the support 10, it can also be unfolded, and when the swing member 30a rotates counterclockwise relative to the support 10, it can also be folded. No specific limitation is made here.

[0056] The technical solution provided by the embodiments of the present invention has a simple synchronization mechanism structure. While realizing the synchronous rotation of the swinging parts, it can effectively reduce the space occupied in the thickness direction, thereby enabling the synchronization mechanism to be fully placed in a limited space. This reduces the difficulty of the installation space requirements during the assembly of the synchronization mechanism, has a wide range of applications, and has low overall processing difficulty. The assembly is simple, flexible and easy to implement, thereby reducing production costs.

[0057] In this embodiment of the invention, the synchronization mechanism can be applied to various devices and mechanisms that require folding actions, including but not limited to foldable phones, laptops, foldable stands, and foldable tablets. For example, when applied to a foldable phone, the foldable phone includes two outer shells, each connected to one of two swinging members 30, thereby enabling synchronous rotation of the two outer shells, i.e., folding and unfolding of the phone. As another example, when the synchronization mechanism is applied to a laptop, the laptop includes a screen and a body, each connected to one of the two swinging members 30, thereby enabling synchronous rotation of the screen and body, i.e., folding and unfolding of the screen and body.

[0058] For example, see Figure 3 A terminal device, such as a mobile phone, includes a main body 40, which includes, but is not limited to, a hinge cover. The main body 40 has a pair of foldable components 41, namely foldable component 41a and foldable component 41b. The foldable components 41 include, but are not limited to, the phone's casing or the phone's screen. Simultaneously, the main body 40 is also provided with a synchronization mechanism. To ensure that the two foldable components 41 receive more even force and move more smoothly when performing folding and unfolding actions, the main body 40 may be provided with multiple synchronization mechanisms, such as... Figure 3 In the embodiment shown, the main body 40 is provided with two synchronization mechanisms, that is, a synchronization mechanism is provided at point A and point B at both ends of the main body 40. Of course, depending on different needs, one or more synchronization mechanisms can also be provided at the position between point A and point B, which is not specifically limited here.

[0059] Combination Figure 3 See Figure 4 and Figure 5 The two swinging members 30 of the synchronization mechanism are respectively connected to a foldable component 41. For example, swinging member 30a is connected to foldable component 41a, and swinging member 30b is connected to foldable component 41b, so that the two foldable components 41 can be driven to perform actions synchronously through the synchronization mechanism.

[0060] Taking the phone's initial state as an example Figure 3Taking the unfolded state shown as an example, when one of the foldable components 41, such as foldable component 41a, rotates clockwise, foldable component 41a drives the swinging component 30a to rotate clockwise. As the swinging component 30a rotates, it drives the synchronous slider 20 to move downward. When the synchronous slider 20 moves downward, it drives the swinging component 30b to rotate counterclockwise relative to the bracket 10. At the same time, the swinging component 30b drives the foldable component 41b to rotate counterclockwise. Based on the synchronization mechanism, the clockwise rotation of foldable component 41a and the counterclockwise rotation of foldable component 41b are performed synchronously. Therefore, the synchronous folding action of the two foldable components 41 is achieved. The state of the foldable component 41 after completing the folding action can be seen in [reference needed]. Figure 6 As shown.

[0061] When you need to take your phone from... Figure 6 When unfolded from the folded state shown, the foldable component 41a rotates counterclockwise relative to the support 10. The foldable component 41a then rotates the swinging component 30a counterclockwise relative to the support 10. The swinging component 30a, via the synchronous slider 20, synchronously rotates the swinging component 30b clockwise. The swinging component 30b then rotates the foldable component 41b clockwise, thus achieving synchronous unfolding of the two foldable components 41. The unfolded state of the foldable component 41 can be seen in [reference needed]. Figure 3 As shown.

[0062] See also Figure 1 and Figure 2 In some feasible embodiments of the present invention, the first direction can be implemented in various ways. One feasible way is that the first direction is the thickness direction of the support 10.

[0063] Another possible way to achieve the first direction is, as follows: Figure 1 As shown, the two swinging members 30 are rotatably connected to the bracket 10 via two parallel axes of rotation, which are respectively... Figure 1 The rotation axes L1 and L2 are shown by the dashed lines. Rotation axes L1 and L2 are parallel to each other, and the first direction is perpendicular to the plane containing the two rotation axes. Further, see... Figure 2 The plane shown by the X-axis is the plane containing the two rotation axes, and the extension direction of the Y-axis perpendicular to the X-axis is the first direction.

[0064] Another possible way to achieve the first direction is, Figure 2 The direction of the Y-axis in the diagram is the first direction. One implementation of the Y-axis is that when the two oscillating members 30 rotate in opposite directions to the first stop position, the two oscillating members 30 are in an extended state, such as... Figure 2 The state shown is that the two swinging members 30 are in the extended state, facing each other. Figure 2 The direction indicated by the solid arrow. When the two swinging members 30 rotate to the second stop position in opposite directions, the two swinging members 30 are in a folded state, i.e., in opposite directions. Figure 2 The direction indicated by the dashed arrow.

[0065] Specifically, when the swinging components 30a and 30b stop rotating towards each other, their positions are designated as the first stop position. At this first stop position, the swinging components 30a and 30b cease rotation and are in a folded state. When the swinging components 30a and 30b stop rotating in opposite directions, their positions are designated as the second stop position. At this second stop position, the swinging components 30a and 30b cease rotation and are in an unfolded state.

[0066] A directional coordinate system is established with the extension direction of the swing member 30 in its unfolded state as the X-axis and the extension direction of the swing member 30 in its folded state as the Y-axis. The extension direction of the Y-axis is the first direction. Figure 2 Taking the Chinese position as an example, the extension direction of the Y-axis is also the up and down direction, or the extension direction of the Y-axis is the vertical direction, and correspondingly, the extension direction of the X-axis is the horizontal direction.

[0067] See also Figure 1 and Figure 2 To enable the synchronous slider 20 to better complete the transmission action, in some feasible embodiments of the present invention, the bracket 10 is provided with a first limiting structure 11. The synchronous slider 20 is provided with a second limiting structure 21, which is movably connected to the first limiting structure 11, and the first limiting structure 11 limits the movement of the second limiting structure 21 along a first direction. The bracket 10 can effectively limit the movement direction of the synchronous slider 20 through the first limiting structure 11 and the second limiting structure 21, for example, with Figure 1 and Figure 2 Taking the center position as an example, the first limiting structure 11 and the second limiting structure 21 limit the synchronous slider 20 to move up and down relative to the bracket 10 along the thickness direction of the bracket 10, thereby reducing the movement of the slider 20.

[0068] The irregular movement of the synchronous slider 20 reduces the loss of transmission action, enabling the synchronous slider 20 to transmit the transmission action to the swing member 30 faster and more directly, thereby better realizing the synchronous rotation of the two swing members 30.

[0069] Furthermore, in some feasible embodiments of the present invention, the first limiting structure 11 and the second limiting structure 21 can be implemented in various ways. One feasible method is, see [link to relevant documentation]. Figure 1 One of the first limiting structure 11 and the second limiting structure 21 is a groove structure, and the other is a protrusion structure used in conjunction with the groove structure. For example, the first...

[0070] The limiting structure 11 is a groove structure, and the second limiting structure 21 is a protrusion structure. The groove opening faces the direction of the synchronous slider 0 20, so that the protrusion structure on the synchronous slider 20 can extend into the groove structure. Depending on different requirements, the groove...

[0071] The structure can form a slide for the protruding structure to move along the thickness direction of the support 10, i.e., along the first direction. The slide may or may not penetrate the support 10, or may only penetrate the top or bottom of the support 10. When one of the two swing members 30 rotates relative to the support 10, for example, when the swing member 30a rotates clockwise, as the swing member 30a rotates, the base...

[0072] Due to the limiting effect of the groove and protrusion structures, the synchronous slider 20 can only move in the upward and downward directions limited by the groove and protrusion structures. That is, when the swing member 30a rotates clockwise, the swing member 30a will drive the synchronous slider 20 to move downward.

[0073] When the step slider 20 moves downward, it drives the oscillating member 30b to rotate counterclockwise relative to the bracket 10, thus achieving synchronous rotation of the two oscillating members 30 in opposite directions. Due to the limiting effect of the groove and protrusion structures, the synchronous slider 20 only moves vertically and not in other directions, allowing for rapid and direct transmission of the motion to the oscillating member 30b, thereby achieving synchronous movement of the two oscillating members 30.

[0074] Of course, depending on different needs, the first limiting structure 11 can also be a protruding structure, and the second limiting structure 21 can be a groove.

[0075] Alternatively, the first limiting structure 11 may be a combination of a protruding structure and a groove structure, and the second limiting structure 21 may be a concave-convex structure used in conjunction with the first limiting structure 11. The embodiments of the present invention are not specifically limited here.

[0076] In some feasible embodiments of the present invention, the rotatable connection between the swing member 30 and the bracket 10 can be achieved in various ways. One feasible way is to continue reading... Figure 1 and Figure 2 One of the bracket 10 and the swing member 30 is provided with a first rotating shaft 12, and the other is provided with a first shaft hole 31 for use with the first rotating shaft 12. The first rotating shaft 12 and the first shaft hole 31 are connected.

[0077] A shaft hole 31 allows for rotatable connection. For example, the bracket 10 has a first rotating shaft 12, and the swing member 30 has a first shaft hole 31. The swing member 30 is sleeved on the first rotating shaft 12 through the first shaft hole 31 and can rotate around the ground-mounted first rotating shaft 12. Alternatively, the bracket 10 has a first shaft hole 31, and the swing member 30 has a first rotating shaft 12. The swing member 30 is rotatably connected via...

[0078] The first rotating shaft 12 is inserted into the first shaft hole 31 and can rotate around the first rotating shaft 12. Further, to better achieve rotation between the first rotating shaft 12 and the first shaft hole 31, the contact portion between the first rotating shaft 12 and the first shaft hole 31...

[0079] The components may be provided with a self-lubricating layer, such as a Teflon material layer on the surface of the first rotating shaft 12 and the inner surface of the first shaft hole 31.

[0080] Another possible way to achieve the rotatable connection between the swing member 30 and the bracket 10 is that both the bracket 10 and the swing member 30 are provided with second shaft holes, and a second rotating shaft passes through the second shaft holes on the bracket 10 and the swing member 30 to achieve swinging.

[0081] The component 30 is rotatably connected to the bracket 10. When connecting the bracket 10 and the swing component 30, the positions of the second shaft holes 5 on the bracket 10 and the swing component 30 are aligned accordingly. Then, the second rotating shaft passes through the two second shaft holes respectively. The second rotating shaft is interference-fitted with the second shaft hole on the bracket 10 or the second shaft hole on the swing component 30, so that the second rotating shaft is fixedly connected to one of the bracket 10 and the swing component 30, and rotatably connected to the other, thereby realizing the rotatable connection between the swing component 30 and the bracket 10. Of course, a self-lubricating layer can also be provided on the second rotating shaft.

[0082] Depending on different requirements, the transmission methods between the synchronous slider 20 and the oscillating component 30 include various methods. One transmission method 0 is... (See...) Figure 1 and Figure 2The synchronizer slider 20 has a first hinge structure 22 at each end corresponding to the swing member 30, and the swing member 30 has a second hinge structure 32 at the position corresponding to the first hinge structure 22. The first hinge structure 22 and the second hinge structure 32 are movably hinged together. When one swing member 30 rotates relative to the support 10, the swing member 30 drives the synchronizer slider 20 to move relative to the support 10 in a first direction through the second hinge structure 32, so as to drive the other swing member 30 to rotate synchronously. For example, when the swing member 30a rotates relative to the support 10, the second hinge structure 32 rotates synchronously around the first axis 12 as the swing member 30 rotates. To prevent the first hinge structure 22 from obstructing the rotation of the second hinge structure 32, the second hinge structure 32 will move relative to the first hinge structure 22 when it rotates. At the same time, as the second hinge structure 32 moves, it will drive the synchronous slider 20 to move. The movement of the synchronous slider 20 will drive the swing member 30b to rotate synchronously with the swing member 30a, thereby realizing that the swing member 30b moves synchronously with the swing member 30a.

[0083] Furthermore, in some feasible embodiments of the present invention, one possible implementation of the first hinge structure 22 and the second hinge structure 32 is that the first hinge structure 22 is a hinge slot or hinge hole, and the second hinge structure 32 is a moving block used in conjunction with the hinge slot or hinge hole. The moving block can move relative to the hinge slot or hinge hole along a second direction, which is perpendicular to the first direction. The second direction is a horizontal direction, or as... Figure 2 As shown, the direction in which the X-axis extends is the second direction.

[0084] One implementation of the hinge slot or hinge hole is that the hinge slot or hinge hole extends in a horizontal direction or in a second direction to form a space for the movement of the moving block. The moving block includes, but is not limited to, a cylindrical structure.

[0085] For example, see [link to previous article] Figure 1 and Figure 2 The swing member 30a is rotatably connected to the bracket 10 via a first shaft hole 31 and a first rotating shaft 12 on the bracket 10. The moving block is fixed on one end face of the swing member 30a. When the swing member 30a rotates, it drives the moving block to move synchronously around the circumferential direction of the first rotating shaft 12. The swing member 30b is rotatably connected to the bracket 10 via a first shaft hole 31 and another first rotating shaft 12 on the bracket 10. The moving block is fixed on one end face of the swing member 30b. When the swing member 30b rotates, it drives the moving block to move synchronously around the circumferential direction of the other first rotating shaft 12.

[0086] The synchronous slider 20 has two hinge slots corresponding to the swing members 30a and 30b respectively. The synchronous slider 20 also has a protrusion that engages with the groove structure on the support 10. The moving blocks on the two swing members 30 are movably hinged to their corresponding hinge slots, meaning the moving blocks can move relative to the hinge slots along the extension direction of the slots to achieve a sliding fit. The protrusion structure and the groove structure are in sliding fit. When one of the swing members 30a and 30b rotates relative to the support 10, as shown in the figure... Figure 1 and Figure 2 Taking the orientation as an example, the swing member 30 is initially in the unfolded state. When the swing member 30a rotates clockwise, it drives the moving block on it to move clockwise around the first rotating shaft 12. The moving block moves relative to the hinge slot along the second direction, that is, first to the right a certain distance, and then to the left. At the same time, the movement of the moving block drives the synchronous slider 20 to move downward. When the synchronous slider 20 moves downward, it drives the moving block on the swing member 30b to move along the second direction through another hinge slot, thereby realizing the synchronous mirror motion of the two moving blocks, and thus making the swing member 30a and the swing member 30b move synchronously in a mirror manner.

[0087] Furthermore, in some possible embodiments of the present invention, see also... Figure 1 and Figure 2 One configuration of the moving block is as follows: one end of the swing member 30 is provided with a transition ring 301, and the swing member 30 is rotatably connected to the bracket 10 through the transition ring 301. The moving block is disposed on the axial end face of the transition ring 301 facing the synchronous slider 20. When the swing member 30 rotates relative to the bracket 10, it drives the moving block to move circumferentially along the transition ring 301 through the transition ring 301. Simultaneously, the moving block moves relative to the synchronous slider 20 in a second direction, thereby driving the synchronous slider 20 to move in a first direction. When the swing member 30 rotates relative to the bracket 10, the transition ring 301 rotates synchronously. As the transition ring 301 rotates, the moving block moves circumferentially along the transition ring 301, and the movement trajectory is an arc. At the same time, the moving block moves relative to the synchronous slider 20 along the extension direction of the hinge groove or hinge hole, that is, along the second direction. The trajectory of the movement is a horizontal straight line. Through the movement of the moving block in both arc and straight lines, the moving block can drive the synchronous slider 20 to move along the first direction, thereby realizing the synchronous mirror motion of the swing member 30a and the swing member 30b.

[0088] Furthermore, another transmission method between the synchronous slider 20 and the oscillating member 30 is, see [link to relevant documentation] Figure 7 and Figure 8The synchronizer slider 20 has a first gear set 23 at each end corresponding to the swing member 30, and a second gear set 33 at the position corresponding to the first gear set 23 on the swing member 30. The first gear set 23 and the second gear set 33 are engaged. Both the first gear set 23 and the second gear set 33 include multiple teeth for engagement. When one swing member 30 rotates relative to the support 10, the swing member 30 drives the synchronizer slider 20 to move relative to the support 10 in a first direction through the second gear set 33, so as to drive the other swing member 30 to rotate synchronously. For example, when the swing member 30a rotates relative to the support 10, the second gear set 33 rotates synchronously around the first rotating shaft 12 as the swing member 30 rotates. As the second gear set 33 moves, it drives the first gear set 23 to move synchronously, thereby driving the synchronizer slider 20 to move. The movement of the synchronizer slider 20 causes the swing member 30b to rotate synchronously with the swing member 30a.

[0089] For example, the swing member 30a is rotatably connected to the support 10 via a first shaft hole 31 and a first rotating shaft 12 on the support 10. The second gear set 33 is fixed on the end face of the swing member 30a facing the synchronous slider 20. When the swing member 30a rotates, it drives the second gear set 33 to move synchronously. The swing member 30b is rotatably connected to the support 10 via a first shaft hole 31 and another first rotating shaft 12 on the support 10. The second gear set 33 is fixed on the end face of the swing member 30b facing the synchronous slider 20. When the swing member 30b rotates, it drives the second gear set 33 to move synchronously.

[0090] The synchronous slider 20 is provided with first gear sets 23 corresponding to the swing members 30a and 30b respectively. The second gear sets 33 on the two swing members 30 are respectively engaged with their corresponding first gear sets 23. When one of the swing members 30a and 30b rotates relative to the support 10, as shown in the figure... Figure 3 and Figure 4 Taking the orientation as an example, when the swing member 30a rotates clockwise, it drives the second gear group 33 on it to rotate clockwise. The second gear group 33 moves relative to the first gear group 23, thereby driving the synchronous slider 20 to move downward through the first gear group 23. When the synchronous slider 20 moves downward, it drives the second gear group 33 on the swing member 30b to move through another first gear group 23, thus realizing the synchronous mirror motion of the two second gear groups 33, making the swing member 30a and the swing member 30b move synchronously in a mirror manner.

[0091] Furthermore, in some possible embodiments of the present invention, see also... Figure 7 and Figure 8One configuration of the second gear group 33 is as follows: one end of the swing member 30 is provided with a transition ring 301, and the swing member 30 is rotatably connected to the bracket 10 through the transition ring 301. The second gear group 33 is disposed on the circumferential side of the transition ring 301 facing the synchronous slider. This configuration of the second gear group 33 facilitates the meshing connection between the swing member 30 and the synchronous slider 20, and also facilitates the application of force by the swing member 30 to the synchronous slider 20, making the movement of the synchronous slider 20 driven by the swing member 30 less strenuous and easier to operate.

[0092] Furthermore, depending on the different rotation amplitude requirements of the oscillating member 30, the arc length of the area on the adapter ring 301 used to set the second tooth group 33 can also be set accordingly. For example, when the required rotation amplitude of the oscillating member 30 is large, the second tooth group 33 can be set in a region with a longer arc length, so that the second tooth group 33 can contain a larger number of teeth, thereby cooperating with the first tooth group 23 on the synchronous slider 20 to achieve a larger rotation amplitude of the oscillating member 30. Correspondingly, when the required rotation amplitude of the oscillating member 30 is small, the second tooth group 33 can be set in a region with a shorter arc length, so that the second tooth group 33 can contain a smaller number of teeth, thereby cooperating with the first tooth group 23 on the synchronous slider 20 to achieve a smaller rotation amplitude of the oscillating member 30. In some embodiments of the present invention, the arc length of the region on the adapter ring 301 where the second tooth group 33 is provided is at least 1 / 4 of the circumference of the outer ring of the adapter ring 301, thereby satisfying that the rotation amplitude of the oscillating member 30 is 1 / 4 circle. Of course, in this embodiment of the invention, the arc length of the area on the adapter ring 301 where the second tooth group 33 is provided is not limited, and the arc length of the area on the adapter ring 301 where the second tooth group 33 is provided can be set according to different needs.

[0093] In some feasible embodiments of the present invention, the synchronization mechanism described above, achieved through different transmission methods between the synchronization slider 20 and the swing member 30, can be applied individually to the terminal device or combined together for application to the terminal device. See also Figure 9 and Figure 10 Two or more synchronization mechanisms can be set simultaneously on the terminal device. The transmission methods between the synchronization slider 20 and the swing member 30 on different synchronization structures can be the same or different. For example, when two or more synchronization mechanisms are set on the terminal device, the transmission method between the synchronization slider 20 and the swing member 30 on some of the synchronization mechanisms can be as follows: Figure 1 and Figure 2 The hinged connection shown can be used as follows: the transmission method between the synchronizing slider 20 and the swing member 30 on the other part of the synchronizing mechanism can be as follows: Figure 7 and Figure 8 The meshing method is shown.

[0094] Taking a mobile phone as an example, see Figures 3 to 5 A synchronization mechanism is installed at points A and B on the mobile phone, respectively. See Figure 4 The synchronization mechanism located in area A has a synchronization slider 20 that is movably hinged to the second hinge structure 32 of the swing member 30 via a first hinge structure 22. The synchronization mechanism located in area B has a synchronization slider 20 that is engaged with the second meshing gear group 33 of the swing member 30 via a first meshing gear group 23.

[0095] Alternatively, the transmission method between the synchronization slider 20 and the swing element 30 on all synchronization mechanisms of the terminal equipment is as follows: Figure 1 and Figure 2 The hinge method shown, or all of them are as follows Figure 7 and Figure 8 The meshing method is shown. The transmission method between the synchronizing slider 20 and the swinging member 30 in the synchronizing mechanism can be set according to different needs, and the embodiments of the present invention do not make specific limitations.

[0096] Furthermore, in some feasible embodiments of the present invention, the hinge and engagement methods can also be combined. One feasible method is that, along the direction from near to far from the support 10, the synchronous slider 20 includes a connecting section, a first transmission section, and a second transmission section. The first transmission section has a third gear set, and the second transmission section has a third hinge structure. The connecting section is movably connected to the support 10. The swing member 30 has a fourth gear set at a position corresponding to the third gear set, and the third and fourth gear sets are engaged. The swing member 30 has a fourth hinge structure at a position corresponding to the third hinge structure, and the third and fourth hinge structures are movably hinged. When the swing member 30 rotates relative to the support 10, the swing member 30 synchronously drives the synchronous slider 20 to move relative to the support 10 through the fourth gear set and the fourth hinge structure, so that the synchronous slider 20 drives the two swing members 30 to rotate synchronously. The articulation and engagement methods are integrated into a single synchronous slider 20, which allows the synchronous slider 20 and the swing member 30 to be connected and transmitted in multiple ways. The diverse connection and transmission methods, along with multiple connection points, make the connection more stable, thereby making the transmission action of the synchronous slider 20 more stable and better achieving synchronization of the actions of the two swing members 30.

[0097] The implementation methods of the third and fourth gear groups can refer to the implementation methods of the first gear group 23 and the second gear group 33 in the above embodiments. The implementation methods of the third and fourth hinge structures can refer to the implementation methods of the first hinge structure 22 and the second hinge structure 32 in the above embodiments. They will not be described in detail here.

[0098] Furthermore, in some feasible embodiments of the present invention, the synchronization mechanism can be provided with different numbers of supports 10 according to different needs, thereby further improving the performance of the synchronization mechanism. One possible implementation is, see [link to relevant documentation]. Figure 1 and Figure 4 The bracket 10 consists of one unit, and the synchronous slider 20 is located on one side of the bracket 10. This arrangement effectively reduces the number of parts, thereby achieving synchronous movement of the swing component 30 with fewer parts, simplifying the structure, reducing space occupation, and reducing manufacturing costs.

[0099] Another possible way to achieve this is, see [link to relevant documentation] Figure 5 There are two brackets 10, and the synchronous slider 20 is located between the two brackets 10. In this configuration, the two brackets 10 can simultaneously provide support and limit for the synchronous slider 20, which can better ensure the stability of the position and movement of the synchronous slider 20, reduce the possibility of erroneous movement of the synchronous slider 20, and thus affect the synchronous movement of the two swinging parts 30.

[0100] Furthermore, in some feasible embodiments of the present invention, to better facilitate the assembly between the synchronization mechanism and other components on the terminal device, the bracket 10 is provided with a mating structure 101 for accommodating the assembly of external components. External components refer to components other than the synchronization mechanism. The mating structure 101 includes, but is not limited to, an arc-shaped groove, which can be adapted to the installation of other components, making the structure of the terminal device more compact, allowing for more rational use of space, and resulting in a more rational layout between components.

The main body 40 has two foldable components 41, which are respectively connected to two swinging members 30 on the synchronization mechanism, so that the synchronization mechanism drives the two foldable components 41 to perform actions synchronously.

Furthermore, in... Figure 1 , Figure 2 , Figures 7 to 10 The foldable component 41 on the main body 40 is also not shown.

The implementation method of the synchronization mechanism will not be repeated here. If there is no structural conflict, the implementation method of the synchronization mechanism in this embodiment can refer to or draw on the implementation method of the synchronization mechanism described in the above embodiments.

[0105] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
