[0010] In one embodiment, in a direction perpendicular to the first frame body and the second frame body, in a first state, a distance between the first connection end and the second frame body is greater than a distance between the first connection end and the second frame body in a second state.

[0011] In one embodiment, in a direction perpendicular to the first frame and the second frame, a distance between the three connection ends and the second frame is smaller than a distance between the four connection ends and the second frame.

[0017] The technical solutions provided by the embodiments of the present disclosure may have the following beneficial effects:

[0018] The float plate adjustment mechanism in this embodiment includes a bracket, a middle frame, a connecting assembly, and a float plate. The first frame has a guide groove, the float plate has a guide block positioned within the guide groove, and the connecting assembly is rotatably connected to the float plate, the second frame, and the bracket. As the middle frame rotates relative to the bracket, the connecting assembly can drive the float plate to move in the direction guided by the guide groove. When the bracket, the float plate, and the first frame are aligned, this provides better support for components located on the bracket, the float plate, and the first frame. When the middle frame and bracket are bent, the float plate moves closer to the second frame. In this case, the distance between the float plate and the second frame is smaller than when the bracket, the float plate, and the first frame are aligned. This increases the space in the area where the float plate faces away from the second frame, thereby providing more space for other components. When the middle frame and bracket are bent, if there are bendable components on the bracket and the first frame, this provides more room for these components to bend.

[0019] For example, this floating plate adjustment structure can be applied to foldable electronic devices with displays. This increases the distance between the floating plate and the display when the middle frame and bracket are bent, providing more room for the display to bend. This reduces the aggravation of creases caused by a smaller bending space and improves the crease quality of the display. It also reduces the pressure exerted by the floating plate on the display, thereby minimizing the excessive stress between the floating plate and the display caused by contact between the display and the floating plate during a fall or other collision. This reduces damage to the display, reduces the risk of display failure, and increases the display's service life.

[0020] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0032] refer to Figure 1 , is a schematic diagram of a floating plate adjustment mechanism, Figure 2 is another schematic diagram of the floating plate adjustment mechanism. Figure 3 is another schematic diagram of the floating plate adjustment mechanism. Figure 4 A schematic diagram of a middle frame. Figure 5 A schematic diagram of a floating plate, combined with Figures 1 to 5 , the agency includes:

[0033] Bracket 1.

[0034] The middle frame 2 includes a first frame body a and a second frame body b connected in a stepped manner, wherein the first frame body a is higher than the second frame body b; and a guide groove a1 is formed on the first frame body a.

[0035] The floating plate 3 overlaps with the second frame b; wherein the floating plate 3 has a guide block 301, and the guide block 301 is located in the guide groove a1.

[0036] The connecting assembly 4 is rotatably connected to the bracket 1 , the second frame b and the floating plate 3 , respectively, and is at least used to drive the floating plate 3 to move along the guide groove a1 .

[0037] In the first state, the floating plate 3, the bracket 1, and the first frame a are flush, and a first distance h1 exists between the floating plate 3 and the second frame b. In the second state, the bracket 1 and the middle frame 2 are bent, and a second distance h2 exists between the floating plate 3 and the second frame b. The first distance h1 is greater than the second distance h2.

[0038] The floating plate adjustment mechanism can be applied to at least foldable terminal devices, such as foldable mobile phones, foldable tablet computers, foldable wearable devices, and other foldable terminal devices. Exemplarily, at least the folding area of ​​these foldable terminal devices has a display screen.

[0039] The bracket 1 can serve as a support component for the display screen of the hinge portion of a foldable terminal device. The foldable terminal includes a hinge, a first terminal body, and a second terminal body. The first terminal body and the second terminal body are respectively connected to the hinge. The first terminal body and the second terminal body can rotate about the hinge, thereby realizing the first terminal body and the second terminal body to be unfolded and folded. It can also realize a state between unfolding and folding, such as hovering. The hovering angle is between unfolding and folding, and the hovering angle can be between 0 degrees and 180 degrees.

[0040] Exemplarily, the bracket 1 may include a support plate, such as a flat plate.

[0041] Exemplarily, the bracket 1 can serve as a rotating shaft.

[0042] The structure, size and shape of the bracket 1 are not limited and can be determined according to actual needs. Figures 1 to 3 As shown, the bracket 1 is a cubic structure. The size of the bracket 1 can be determined according to the size of the foldable terminal device, and the size of the bracket 1 may be different in different foldable terminal devices.

[0043] The middle frame 2 is the middle frame of the foldable terminal device. The middle frame 2 can be the middle frame of the first terminal body and the second terminal body. The middle frame 2 can include a first frame body a and a second frame body b. The first frame body a and the second frame b are connected. The first frame body a and the second frame b together serve as the middle frame 2. Figure 4 The first frame a and the second frame b are connected in a stepped manner, the first frame a is higher than the second frame b, and the first frame a has a guide groove a1.

[0044] The depth, inner diameter and shape of the guide groove a1 can be determined according to requirements and are not limited here. The guide groove a1 is used to guide the moving path of the floating plate 3.

[0045] For example, the thickness of the first frame a is greater than that of the second frame b. The first frame a has a first surface and a second surface that are opposite to each other, and the second frame b has a third surface and a fourth surface that are opposite to each other. The first surface and the third surface are on the same horizontal plane, that is, the first surface and the third surface are flush; the plane where the second surface is located and the plane where the fourth surface is located are staggered and are not on the same plane. Figure 4 As shown, the second surface is represented by a0 and the fourth surface is represented by b2.

[0046] Exemplarily, the first frame body a and the second frame body b are integrally formed.

[0047] The shape, size, and material of the middle frame 2 can be determined according to the foldable device terminal.

[0048] The floating plate 3 can be a flat-plate component, and the size of the floating plate 3 can be the same as that of the second frame b, or smaller than the second frame b. The larger the floating plate 3 is, the larger the contact area with the display screen 5 is, which is more conducive to supporting the display screen 5 and facilitating better display of the display screen 5.

[0049] Since the first frame a and the second frame b are connected in a stepped manner, the first frame a is higher than the second frame b, so there is a height difference between the second frame b and the first frame a, and there is space above the second frame b to accommodate the floating plate 3. The floating plate 3 can overlap with the second frame b, refer to Figures 1 to 3 , which shows a positional relationship among the floating plate 3, the second frame b and the first frame a.

[0050] refer to Figure 5 The floating plate 3 has a guide block 301 located in the guide groove a1. The size and shape of the guide block 301 can match the guide groove a1. The guide block 301 moves along the guide groove a1, thereby guiding the movement path of the floating plate 3.

[0051] Connecting assembly 4 is rotatably connected to bracket 1, second frame b, and floating plate 3, and is configured to at least drive floating plate 3 along guide groove a1. Connecting assembly 4 may include one or more components configured to drive floating plate 3 along guide groove a1 during relative motion between bracket 1 and middle frame 2.

[0052] Connecting assembly 4 connects bracket 1 and middle frame 2. Connecting assembly 4 is rotationally connected to bracket 1, allowing relative rotation of the two components. For example, if bracket 1 is fixed, connecting assembly 4 can rotate around bracket 1 with bracket 1 as the rotation center. Connecting assembly 4 achieves a rotational connection with middle frame 2 through a rotational connection with second frame b. Connecting assembly 4 and second frame b are rotatable, for example, connecting assembly 4 can rotate relative to second frame b.

[0053] The connection assembly 4 can be rotatably connected to the bracket 1 and the middle frame 2 in various ways, including through a rotating shaft or a gear or other connection methods that can achieve a rotatable connection.

[0054] The connecting assembly 4 is also rotationally connected to the floating plate 3, and the connecting assembly 4 can rotate relative to the floating plate 3. For example, the connecting assembly 4 and the floating plate 3 are connected via a rotating shaft. When the floating plate 3 is fixed, the connecting assembly 4 can rotate about the rotating shaft. The connecting assembly 4 and the floating plate 3 can also be connected via gears or other connection methods that can achieve a rotational connection.

[0055] During the relative movement between the bracket 1 and the middle frame 2, the bracket 1 and the middle frame 2 may be in a first state and a second state. Figure 2 , shows the positional relationship between the floating plate 3, the bracket 1, the first frame a, and the second frame b in the first state. In the first state, the floating plate 3, the bracket 1, and the first frame a are flush, and there is a first distance h1 between the floating plate 3 and the second frame b.

[0056] refer to Figure 1 and Figure 3 , showing the positional relationship between the floating plate 3, bracket 1, first frame a, and second frame b in the second state. In the second state, the bracket 1 and middle frame 2 are bent, and a second distance h2 is defined between the floating plate 3 and the second frame b. The first distance h1 is greater than the second distance h2.

[0057] Figure 1 In the second state shown, the distance between the floating plate 3 and the second frame b is less than Figure 3 In the second state shown, there is a distance between the floating plate 3 and the second frame b.

[0058] For example, Figure 1 In the second state shown, the second distance between the floating plate 3 and the second frame b is the minimum distance between the floating plate 3 and the second frame b. Figure 2In the second state shown, the second distance h1 between the floating plate 3 and the second frame b is the maximum distance between the floating plate 3 and the second frame b.

[0059] From the first state to the second state, the distance between the floating plate 3 and the second frame b gradually decreases, including from maximum to minimum. From the second state to the first state, the distance between the floating plate 3 and the second frame b gradually increases, including from minimum to maximum.

[0060] During the rotation of the middle frame 2 relative to the bracket 1, the connecting assembly 4 can drive the floating plate 3 to move along the direction guided by the guide groove a1. Figure 2 , shows a schematic diagram in a first state, where the bracket 1, the floating plate 3 and the first frame a are flush, that is, in the first state, better support can be provided for the components located on the bracket 1, the floating plate 3 and the first frame a (such as the display screen 5).

[0061] When the middle frame 2 and bracket 1 are bent, i.e., in the second state, the floating plate 3 moves closer to the second frame body b. In this state, the distance between the floating plate 3 and the second frame body b is smaller than in the first state. This increases the space in the area of ​​the floating plate 3 facing away from the second frame body b, providing more room for other components. When the middle frame 2 and bracket 1 are bent, if there are any bendable components on the bracket 1 and the first frame body b, this provides more space for these components to flex.

[0062] For example, this floating plate adjustment structure can be applied to a foldable electronic device with a display screen 5. This increases the distance between the floating plate 3 and the display screen 5 when the middle frame 2 and the bracket 1 are in a bent state, providing more bending space for the display screen 5. This reduces the aggravation of creases caused by a smaller bending space, thereby improving the crease of the display screen. It can also reduce the pressure of the floating plate 3 on the display screen 5, thereby reducing the excessive stress between the floating plate 3 and the display screen 5 caused by the display screen contacting the floating plate 3 when it falls or otherwise impacts. This reduces damage to the display screen 5, reduces the risk of failure of the display screen 5, and increases the service life of the display screen 5.

[0063] In one embodiment, reference Figure 5 , the floating plate 3 includes:

[0064] Floating board body 302;

[0065] Guide block 301;

[0066] The connecting member 303 is connected to the guide block 301 and the floating plate body 302 respectively; wherein the maximum outer diameter of the guide block 301 is greater than the maximum outer diameter of the connecting member 303 .

[0067] The floating plate body 302 serves as the main body of the floating plate 3. The size of the floating plate body 302 is the same as or smaller than the size of the second frame b. When the floating plate body 302 is smaller than the second frame b, the floating plate body 302 can be prevented from protruding from the second frame b, thereby reducing the impact of the floating plate body 302 on other components.

[0068] Connector 303 connects floating plate body 302 and guide block 301. During movement of floating plate body 302, guide block 301 moves along the guide direction of guide groove a1, thereby enabling movement of floating plate body 302. Movement of floating plate body 302 can include movement toward second frame body b, i.e., transitioning from the second state to the first state, and movement away from second frame body b, i.e., transitioning from the first state to the second state.

[0069] The maximum outer diameter of the guide block 301 is greater than the maximum outer diameter of the connecting member 303 , which can prevent the guide block 301 from escaping from the guide groove a1 during the movement of the floating plate 3 , thereby allowing the floating plate 3 to move along the guide groove a1 .

[0070] refer to Figure 6 , which is a schematic diagram of the positional relationship between the floating plate and the middle frame.

[0071] For example, the shape of the connecting member 303 can be determined according to actual needs. Figure 5 One of them is shown, and the connecting member 303 can also be a bent-shaped component, such as a bent plate-like structure.

[0072] In one embodiment, reference Figure 4 , the first frame a also has:

[0073] The opening a2 is located on the side wall of the guide groove a1 and is used to accommodate the connector 303. The opening a2 facilitates the connection of the floating plate 3 with the first frame a through the guide block 301, thereby reducing the overall thickness of the floating plate 3 and facilitating switching to the first state.

[0074] For example, the position of the opening a2 is not limited and can be determined according to actual needs. Figure 4 and Figure 7 As shown, Figure 7 This is a schematic diagram of another floating plate adjustment mechanism, which can be located in the guide groove a1 close to the second frame b and facing the side wall of the bracket 1.

[0075] For example, the opening a2 can also be located on the side wall of the first frame body a near the second frame body b and facing the bracket 1. The opening a2 is connected to the guide groove a1, and the opening a2 and the guide groove a1 form a connecting passage. The inner diameter and shape of the connecting passage can be determined according to needs, and the outer diameter of the connecting member 303 matches the inner diameter of the connecting passage.

[0076] In one embodiment, the depth of the guide groove a1 is less than or equal to the difference, where the difference is the height difference between the first frame a and the second frame b.

[0077] Due to the height difference between the first frame a and the second frame b, the floating plate 3 moves toward the second frame b, but only to the point where it abuts the second frame b. Therefore, the depth of the guide groove a1 is less than or equal to the height difference between the first frame a and the second frame b. This reduces the likelihood that the guide groove a1 will penetrate the first frame a, reduces the depth of the guide groove a1, and thus reduces the impact of the guide groove a1 on the strength of the first frame a.

[0078] In one embodiment, reference Figure 7 , is another schematic diagram of a floating plate adjustment mechanism; Figure 8 , is another schematic diagram of a floating plate adjustment mechanism; Figure 9 , is another schematic diagram of a floating plate adjustment mechanism; combined Figures 7 to 9 , the connection component 4 includes:

[0079] The first connecting arm 401 has a first connecting end 4011 and a second connecting end 4012 . The first connecting end 4011 is rotatably connected to the bracket 1 , and the second connecting end 4012 is rotatably connected to the second frame b.

[0080] The second connecting arm 402 has a third connecting end 4021 and a fourth connecting end 4022 . The third connecting end 4021 is rotatably connected to the first connecting arm 401 , and the fourth connecting end 4022 is rotatably connected to the floating plate 3 .

[0081] The first connecting arm 401 and the second connecting arm 402 may include a swing arm or a connecting rod. The size and shape of the first connecting arm 401 and the second connecting arm 402 are not limited and may be cylindrical, plate-shaped or other shapes.

[0082] The bracket 1 and the middle frame 2 are connected via the first connecting arm 401, and the floating plate 3 is connected to the first connecting arm 401 via the second connecting arm 402. The combination of the first connecting arm 401 and the second connecting arm 402 allows the first connecting arm 401 to drive the second connecting arm 402 during the switching process between the first state and the second state, thereby driving the floating plate 3 to move. This allows the floating plate 3 to be adjusted so that it can change in response to changes in the relative position or shape between the middle frame 2 and the bracket 1.

[0083] In one embodiment, in a direction perpendicular to the first frame a and the second frame b, in the first state, a distance h3 between the first connection end 4011 and the second frame b is greater than a distance h4 between the first connection end 4011 and the second frame b in the second state.

[0084] Figure 2 shows the distance h3 between the first connection end 4011 and the second frame b in the first state, Figure 1 and Figure 3 The diagram shows that in the second state, the distance h4 between the first connection end 4011 and the second frame b is greater than h4, and h3 is greater than h4. During the transition from the second state to the first state, the distance between the first connection end 4011 and the second frame b gradually increases. Since the connection point between the second connection end 4012 and the second frame b is a fixed point, the second connection end 4012 is fixed relative to the second frame b. Therefore, after the distance between the first connection end 4011 and the second frame b gradually increases, the third connection end 4021 moves toward the first frame a, thereby driving the floating plate 3 to move away from the second frame b, increasing the distance between the floating plate 3 and the second frame b.

[0085] On the contrary, during the process of switching from the first state to the second state, the distance between the first connection end 4011 and the second frame b gradually decreases, and the third connection end 4021 moves in the direction away from the first frame a, thereby driving the floating plate 3 to move in the direction close to the second frame b, so that the distance between the floating plate 3 and the second frame b is reduced.

[0086] In one embodiment, according to Figures 1 to 3 as well as Figure 9 , showing that in a direction perpendicular to the first frame and the second frame, the distance between the third connection end 4021 and the second frame b is smaller than the distance between the fourth connection end 4022 and the second frame b.

[0087] In this way, during the transition from the first state to the second state, after the first connecting arm 401 drives the second connecting arm 402, the second connecting arm 402 drives the floating plate 3 toward the second frame b, thereby reducing the distance between the floating plate 3 and the second frame b. Alternatively, during the transition from the second state to the first state, after the first connecting arm 401 drives the second connecting arm 402, the second connecting arm 402 drives the floating plate 3 toward the second frame b, thereby increasing the distance between the floating plate 3 and the second frame b.

[0088] In one embodiment, reference Figure 7 and Figure 9 The first frame a has a first protrusion a3, and the first protrusion a3 has a first connecting shaft a4. The second connecting end 4012 has a first shaft hole (not shown in the figure), and the first connecting shaft a4 is located in the first shaft hole.

[0089] In one embodiment, the first protrusion a3 has a first axial hole, the second connecting end 4012 has a first connecting shaft, and the first connecting shaft is located in the first axial hole.

[0090] In one embodiment, the first connecting arm 401 further has a second connecting shaft 4013 , and the third connecting end 4021 has a second shaft hole (not shown in the figure), and the second connecting shaft 4013 is located in the second shaft hole.

[0091] In one embodiment, the first connecting arm 401 has a second axial hole (not shown in the figure), and the third connecting end 4021 has a second connecting shaft, which is located in the second axial hole.

[0092] The above embodiment provides several different rotational connection modes between the first connecting arm 401 and the second connecting arm 402 .

[0093] In one embodiment, reference Figure 8 The floating plate 3 has a third connecting shaft 304, and the fourth connecting end 4022 has a third shaft hole (not shown in the figure), and the third connecting shaft 304 is located in the third shaft hole.

[0094] In one embodiment, the floating plate 3 has a third axial hole, the fourth connecting end 4022 has a third connecting shaft, and the third connecting shaft is located in the third axial hole.

[0095] In one embodiment, a folding mechanism is also provided, referring to Figures 1 to 3 as well as Figures 7 to 9 , the folding mechanism comprises:

[0096] The two floating plate adjustment mechanisms in any of the above-mentioned embodiments, i.e., the number of floating plate adjustment mechanisms is two, and the floating plate adjustment mechanisms include a bracket 1, and the two floating plate adjustment mechanisms share the same bracket 1. The structures of the two floating plate adjustment mechanisms in the folding mechanism can be identical, and the brackets in the two plate adjustment mechanisms can be integrally formed and combined into a single bracket. The two floating plate adjustment mechanisms in the folding mechanism are arranged relative to each other. In a first state, the two floating plate adjustment mechanisms are respectively located on either side of the bracket, and the middle frames in the two floating plate adjustment mechanisms can rotate around the bracket to switch states. Each floating plate adjustment mechanism can switch between a first state and a second state.

[0097] For example, the two float adjustment mechanisms in the folding mechanism can be referred to as a first float adjustment mechanism and a second float adjustment mechanism. The middle frame in the first float adjustment mechanism can be referred to as a first middle frame, the float in the first float adjustment mechanism can be referred to as a first float, the bracket in the first float adjustment mechanism can be referred to as a first bracket, and the connecting assembly in the first float adjustment mechanism can be referred to as a first connecting assembly. The middle frame in the second float adjustment mechanism can be referred to as a second middle frame, the float in the second float adjustment mechanism can be referred to as a second float, the bracket in the second float adjustment mechanism can be referred to as a second bracket, and the connecting assembly in the second float adjustment mechanism can be referred to as a second connecting assembly. The first bracket and the second bracket are integrally formed.

[0098] refer to Figures 1 to 3 , also shows a folding mechanism, Figure 2 The folding mechanism is shown in its unfolded state. In the third state, the middle frames of the two floating plate adjustment mechanisms are unfolded, the floating plates, the first frame, and the bracket are flush with each other, and a first distance exists between the floating plates and the second frame of the floating plate adjustment mechanism. For example, in the third state, the middle frames of the two floating plate adjustment mechanisms are located on either side of the bracket.

[0099] Figure 1 It also shows the effect of the folding mechanism in the folded state. Figure 3 The effect of the folding mechanism in the hovering state is shown. In the second state, the middle frames of the two floating plate adjustment mechanisms are bent or fitted together by the brackets, and a second distance exists between the floating plate and the second frame; wherein the first distance is greater than the second distance.

[0100] This folding mechanism can be applied to a foldable electronic device having a display screen 5. This increases the distance between the floating plate 3 and the display screen 5 when the middle frame 2 and the bracket 1 are in a bent state, providing more bending space for the display screen 5. This reduces the aggravation of the crease caused by the small bending space and improves the crease of the display screen. It also reduces the pressure of the floating plate 3 on the display screen 5, thereby reducing the excessive stress between the floating plate 3 and the display screen 5 caused by the display screen contacting the floating plate 3 due to external force in the event of a fall or other collision. This reduces damage to the display screen 5, reduces the risk of failure of the display screen 5, and increases the service life of the display screen 5.
