[0001] The present disclosure relates to the technical field of electronic equipment, and in particular to a rotating module and a terminal device. Background Art

[0002] With the development of flexible organic light-emitting semiconductor (OLED) technology, foldable screen mobile phones have gradually become an important development direction for terminal devices.

[0057] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims

[0058] Figure 1 is a structural schematic diagram of a rotation module shown according to an exemplary embodiment Figure 1 . Figure 2 is a structural schematic diagram of a rotation module shown according to an exemplary embodiment Figure 2 . As Figure 1 and Figure 2 shown, the rotation module 100 includes:

[0059] a hinge bracket 101;

[0060] a moving bar 102, located on the hinge bracket 101, including a first engaging portion 102a facing the hinge bracket 101 and a second engaging portion 102b facing away from the hinge bracket 101;

[0061] two rotating structures 103, distributed on both sides of the moving bar 102, and one of the rotating structures meshes with the first engaging portion 102a; the other rotating structure meshes with the second engaging portion 102b;

[0062] wherein, when the moving bar 102 moves, the two rotating structures 103 rotate synchronously and the rotating directions of the two rotating structures 103 are opposite

[0063] In the embodiments of the present disclosure, the rotation module can be applied to a terminal device with a folding function such as a folding mobile phone. For example, the rotation module can enable the two folding parts to move synchronously during the folding process of the folding mobile phone, so as to realize uniform and symmetric stress on the screen of the folding mobile phone during the bending process; it can also enable a fixed bending angle on the inner sides of the two folding parts during the folding process of the folding mobile phone

[0064] The above-mentioned moving bar is located on the hinge bracket and can move relative to the hinge bracket. In some embodiments, the contact surface between the moving bar and the hinge bracket is smooth. In this way, the smooth contact surface enables the moving bar to move better on the hinge bracket.

[0065] In the embodiments of the present disclosure, the moving bar extends in opposite directions to form a first engaging portion and a second engaging portion. The above-mentioned rotating structure at least includes gears, and the two gears in the two rotating structures can be respectively used to engage with the first engaging portion and the second engaging portion.

[0066] In some embodiments, both the first engaging portion and the second engaging portion can be parallel to the hinge bracket. In some embodiments, the first engaging portion and the second engaging portion can be located on the same plane; in other embodiments, the first engaging portion and the second engaging portion can be located on different planes. In some embodiments, as Figure 2 shown, the moving bar further includes: a connecting column connecting the first engaging portion 102a and the second engaging portion 102b. The connecting column can be perpendicular to the plane where the first engaging portion and the second engaging portion are located. In other embodiments, the moving bar is in a Z shape.

[0067] It should be noted that the connecting column can be used as a limiting member for the gear to rotate on the first engaging portion or the second engaging portion. For example, the connecting column can limit the gear from continuing to rotate in the direction of the first engaging portion or the second engaging portion, thereby being able to limit the rotation angle of the gear. In other embodiments, the connecting column can also be used as a separator to isolate the two gears located on the moving member and reduce the interference generated when the two gears rotate.

[0068] The above-mentioned rotating structure can rotate relative to the hinge bracket. For example, by applying an external force to the rotating structure, the rotating structure can rotate relative to the hinge bracket. Another example is that through the movement of the moving bar, the rotating structure is driven to rotate relative to the hinge bracket.

[0069] In the embodiments of the present disclosure, when the moving bar moves, the two rotating structures rotate synchronously. That is to say, when one of the two rotating structures rotates, the other rotating structure among the two rotating structures will also rotate. Furthermore, based on the engagement of the moving bar and the two rotating structures, synchronous transmission of the two rotating structures on both sides of the moving bar can be achieved.

[0070] It should be noted that both the first engaging portion and the second engaging portion have teeth, and the teeth distribution of the first engaging portion and the teeth distribution of the second engaging portion are the same. For example, the interval between adjacent teeth is the same and / or the tooth size is the same. In this way, when the two rotating structures rotate synchronously, the rotation angles of the two rotating structures are the same.

[0071] In the embodiments of the present disclosure, when the moving bar moves, the rotation directions of the two rotating structures are opposite. That is to say, through the first meshing portion and the second meshing portion facing in opposite directions, the two rotating structures located on opposite sides of the moving bar can be rotated in opposite directions. For example, the rotation direction of one rotating structure can be clockwise rotation, and the rotation direction of the other rotating structure can be counterclockwise rotation.

[0072] It should be noted that the two rotating structures can be connected to two middle frames of a terminal device with a folding screen. Through the synchronous rotation of the two rotating structures, the folding screen of the terminal device can be switched between the unfolded state and the folded state. For example, when the two rotating structures simultaneously rotate away from the hinge bracket until the included angle between the two rotating structures increases to 180 degrees, the two middle frames of the terminal device are in the same plane, and the folding screen of the terminal device is in the unfolded state.

[0073] For another example, when the two rotating structures simultaneously rotate towards the hinge bracket until the included angle between the two rotating structures shrinks to 0 degrees, the two middle frames of the terminal device are parallel, and the folding screen of the terminal device is in the folded state. In the embodiments of the present disclosure, the synchronous rotation of the two rotating structures is achieved through the first meshing portion and the second meshing portion of the moving bar, which can reduce the components for achieving synchronous rotation, reduce the large fitting clearance caused by the accumulation of assembly tolerances due to the assembly of multiple complex components in the rotating module, and improve the effect of synchronous rotation. Furthermore, during the process of driving the folding screen to fold, the folding screen can achieve precise synchronous folding or synchronous unfolding.

[0074] In the embodiments of the present disclosure, the two rotating structures are distributed on opposite sides of the moving bar, and when the moving bar moves, the two rotating structures rotate synchronously and the rotation directions of the two rotating structures are opposite. That is to say, in the embodiments of the present disclosure, only one moving bar is needed to drive the two rotating structures to rotate synchronously and in opposite directions. In this way, the structure of the rotating module can be simplified, the large fitting clearance caused by the accumulation of assembly tolerances due to the complex assembly of the rotating module can be reduced, and the synchronous effect of the rotating module can be improved.

[0075] Moreover, when the moving bar moves, the rotation directions of the rotating structures are opposite. That is to say, the moving bar can drive the two rotating structures to rotate in opposite directions. Furthermore, when the two rotating structures simultaneously rotate away from the hinge bracket, the two rotating structures can be unfolded relative to the hinge bracket; and when the two rotating structures simultaneously rotate towards the hinge bracket, the two rotating structures can be folded relative to the hinge bracket.

[0076] In some embodiments, as Figure 1 and Figure 3 shown, the rotating structure includes: a rotating slider 103a and a gear 103b connecting the rotating slider 103a and the moving bar 102;

[0077] The moving bar is engaged with the gear, and the gear is engaged with the rotating slider; wherein, when the moving bar 102 moves, the two gears 103b of the two rotating structures 103 rotate in opposite directions, and driven by the two gears 103b, the two rotating sliders 103a of the two rotating structures 103 rotate in opposite directions.

[0078] In the embodiments of the present disclosure, one rotating structure corresponds to one rotating slider and one gear. The rotating slider and the gear can cooperate with each other. The rotation of the gear can drive the rotation of the rotating slider, and the rotation of the rotating slider can also drive the rotation of the gear.

[0079] The two gears of the above two rotating structures are distributed on both sides of the moving bar. When the moving bar moves, the two gears connected to the moving bar rotate synchronously and in opposite directions. For example, when the moving bar moves, the rotation direction of one gear can be clockwise, and the rotation direction of the other gear can be counterclockwise.

[0080] Moreover, driven by the two gears, the two rotating sliders connecting the two gears rotate in opposite directions. That is to say, the two rotating sliders in the embodiments of the present disclosure can achieve synchronous rotation through two gears and one moving bar, thereby enabling the rotating module to have a simple structure. Compared with the existing six gears, only two gears are required in the embodiments of the present disclosure, which can reduce the gear meshing points required for synchronization, thereby reducing the meshing virtual positions and reducing the large fitting clearance caused by the accumulation of assembly tolerances due to the complex assembly of multiple gears, improving the synchronous effect of the rotating module.

[0081] In some embodiments, as Figure 3 shown, the rotating slider has a third engaging portion, and the two rotating structures include a first rotating structure A and a second rotating structure B;

[0082] The first engaging portion 102a and the third engaging portion of the rotating slider 103a of the first rotating structure A are respectively engaged at opposite ends of the gear 103b of the first rotating structure A;

[0083] The second engaging portion 102b and the third engaging portion of the rotating slider 103a of the second rotating structure B are respectively engaged at opposite ends of the gear 103b of the second rotating structure B.

[0084] In the embodiments of the present disclosure, the above gear may include a long strip gear, or may also include a gear with teeth at both ends, and the embodiments of the present disclosure do not make any restrictions.

[0085] Among them, the gear of the first rotating structure includes: a first co-rotating shaft, a first set of teeth, and a second set of teeth; the first set of teeth and the second set of teeth are located at both ends of the first co-rotating shaft; the first set of teeth meshes with the first engaging portion; the second set of teeth meshes with the third engaging portion of the rotating slider of the first rotating structure. Among them, the third engaging portion has teeth, and the teeth of the third engaging portion and the second set of teeth are teeth of the same size and shape.

[0086] The gear of the second rotating structure includes: a second co-rotating shaft, a third set of teeth, and a fourth set of teeth; the third set of teeth and the fourth set of teeth are located at both ends of the second co-rotating shaft; the third set of teeth meshes with the second engaging portion; the fourth set of teeth meshes with the third engaging portion of the rotating slider of the second rotating structure. Among them, the third engaging portion has teeth, and the teeth of the third engaging portion and the fourth set of teeth are teeth of the same size and shape.

[0087] In the embodiments of the present disclosure, the first engaging portion and the third engaging portion of the rotating slider of the first rotating structure are respectively meshed at opposite ends of the gear of the first rotating structure. That is to say, the first engaging portion, the third engaging portion of the rotating slider of the first rotating structure, and the gear of the first rotating structure mesh with each other to form the transmission between the first rotating structure and the moving bar.

[0088] The second engaging portion and the third engaging portion of the rotating slider of the second rotating structure are respectively meshed at opposite ends of the gear of the second rotating structure. That is to say, the first engaging portion, the third engaging portion of the rotating slider of the second rotating structure, and the gear of the second rotating structure mesh with each other to form the transmission between the second rotating structure and the moving bar.

[0089] It should be noted that the gear includes a gear shaft and teeth connected to both ends of the gear shaft. The first engaging portion and the third engaging portion of the rotating slider of the first rotating structure can mesh with the teeth located at both ends of the gear in the first rotating structure; the second engaging portion and the third engaging portion of the rotating slider of the second rotating structure can mesh with the teeth located at both ends of the gear in the second rotating structure.

[0090] In some embodiments, as Figure 4 shown, the rotating slider 103a includes:

[0091] a rotating portion 103a1;

[0092] a third engaging portion 103a2, which is located at opposite ends of the rotating slider 103a from the rotating portion 103a1 and can mesh with the gear 103b;

[0093] Among them, when an external force acts on the rotating portion to rotate, the moving bar is driven to move through the third engaging portion and the gear.

[0094] In the embodiments of the present disclosure, the two rotating structures include a first rotating structure and a second rotating structure. When an external force acts on the rotating part of the rotating slider in the first rotating structure, the moving bar can be driven through the third engaging part of the rotating slider in the first rotating structure, the gear of the first rotating structure, and the first engaging part. When the moving bar moves, the rotating part of the second rotating structure can be driven through the second engaging part, the gear of the second rotating structure, and the third engaging part of the rotating slider in the second rotating structure. Furthermore, the transmission between the first rotating structure, the moving bar, and the second rotating structure is realized, so that the rotating sliders of the first rotating structure and the second rotating structure can rotate synchronously.

[0095] It should be noted that the two rotating parts in the two rotating structures can be respectively fixedly connected to the two middle frames of the terminal device. Furthermore, when an external force acts on the rotating part through the middle frame, the two middle frames can rotate synchronously relative to the hinge bracket, and thus the folding or unfolding of the two middle frames can be realized.

[0096] In some embodiments, as Figure 3 shown, the rotating slider further includes:

[0097] A trajectory limiting part, which is oppositely arranged to the third engaging part and is on the same side of the rotating slider as the third engaging part. Wherein, the trajectory limiting part has an arc-shaped guiding groove 103c;

[0098] The surface of the hinge bracket facing the gear has an arc-shaped protrusion 101a;

[0099] The arc-shaped protrusion 101a is embedded in the arc-shaped guiding groove 103c.

[0100] In the embodiments of the present disclosure, the trajectory limiting part is used to limit the rotation trajectory of the rotating slider.

[0101] The above-mentioned arc-shaped protrusion and arc-shaped guiding groove are matched so that the arc-shaped protrusion and arc-shaped guiding groove can slide relative to each other. The matching of the arc-shaped protrusion and arc-shaped guiding groove includes: the size of the arc-shaped protrusion matches the size of the arc-shaped guiding groove; or, the shape of the arc-shaped protrusion matches the shape of the arc-shaped guiding layer.

[0102] It should be noted that when the rotating slider rotates, based on the mutual cooperation of the arc-shaped protrusion and arc-shaped guiding groove, the purpose of limiting the rotation trajectory of the rotating slider can be realized, making the rotation trajectory of the rotating slider more accurate.

[0103] In some embodiments, the trajectory limiting part includes a first arc-shaped block and a second arc-shaped block spaced from the first arc-shaped block;

[0104] The first arc-shaped block and the second arc-shaped block enclose the arc-shaped guiding groove.

[0105] In the embodiments of the present disclosure, the spacing distance between the first arc-shaped block and the second arc-shaped block matches the width of the arc-shaped protrusion. In this way, the arc-shaped protrusion and the arc-shaped guiding groove can cooperate better, and can better limit the movement track of the rotating slider.

[0106] Exemplarily, the first arc-shaped block and the second arc-shaped block may both be half-round blocks or quarter-round blocks, and the embodiments of the present disclosure do not make any restrictions.

[0107] In some embodiments, as Figure 5 and Figure 6 shown, the gear includes a coaxial shaft 103b1 and gear teeth 103b2 located at both ends of the coaxial shaft 103b1;

[0108] The hinge bracket has a fixing groove 101b;

[0109] The gear teeth 103b2 at both ends of the coaxial shaft are located outside the fixing groove, and the middle part 103b3 between the two ends is located inside the fixing groove.

[0110] In the embodiments of the present disclosure, the gear teeth included in the gear are arranged at opposite ends of the coaxial shaft, so that the rotating slider and the moving strip can be respectively engaged with the opposite ends of the gear.

[0111] It should be noted that the middle part between the two ends of the coaxial shaft is located inside the fixing groove of the hinge bracket and can rotate relative to the fixing groove. In some embodiments, the surface of the middle part is smooth. In this way, when the gear rotates, the hindrance of the hinge bracket to the middle part can be reduced, so that the gear can rotate better.

[0112] In the embodiments of the present disclosure, the middle part of the gear is located inside the fixing groove, and the position of the gear relative to the hinge bracket can be regarded as a fixed position, and the position of the rotating slider engaged with the gear relative to the hinge bracket changes as the rotating structure rotates. For example, the rotating slider can rotate close to the hinge bracket, or the rotating slider can rotate away from the hinge bracket, and the embodiments of the present disclosure do not make any restrictions.

[0113] In some embodiments, as Figure 5 and Figure 6 shown, the rotating module further includes:

[0114] A gear pressing block 104, fixed on the hinge bracket 101 and covering the opening of the fixing groove 101b;

[0115] The middle part 103b3 is located between the gear pressing block 104 and the hinge bracket 101.

[0116] That is to say, by covering the opening of the fixed groove with the gear pressing block, the gear can be fixed on the hinge bracket without affecting the rotation of the gear.

[0117] The above-mentioned gear pressing block can be fixed on the hinge bracket through nuts and screws. For example, nuts are provided on the hinge bracket, through holes are provided on the gear pressing block, and screws pass through the through holes and are connected to the nuts to fix the gear pressing block on the hinge bracket.

[0118] In some embodiments, as Figure 6 shown, the moving bar 102 is located between two gear pressing blocks 104 on the two gears.

[0119] In the embodiments of the present disclosure, by arranging the moving bar between two gear pressing blocks, the moving bar can be restricted to move only in the direction perpendicular to the connection between the two gear pressing blocks, and cannot move in the connection direction between the two gear pressing blocks, thereby playing a role in restricting the moving direction of the moving bar.

[0120] In some embodiments, as Figure 2 shown, a moving guide groove 101c is formed on the hinge bracket 101;

[0121] The second engaging portion 102b is embedded in the moving guide groove 101c.

[0122] That is to say, the second engaging portion of the moving bar can move in the moving guide groove. The moving guide groove can be used to restrict the moving distance and moving direction of the moving bar.

[0123] In the embodiments of the present disclosure, the contact surface between the second engaging portion and the bottom of the moving guide groove is smooth, so that the second engaging portion can move better in the moving guide groove.

[0124] The embodiments of the present disclosure also propose a terminal device, as Figure 7 shown, the terminal device includes:

[0125] A first middle frame 201;

[0126] A second middle frame 202;

[0127] At least one rotation module 100 in one or more of the above embodiments, located in a hinge groove 203 formed by the first middle frame and the second middle frame, and two rotation structures of the rotation module 100 are respectively fixed on the first middle frame and the second middle frame;

[0128] Wherein, when the two rotation structures rotate synchronously, the first middle frame and the second middle frame are driven to rotate synchronously.

[0129] The above-mentioned terminal device is a terminal device provided with a flexible screen. The terminal device includes a wearable electronic device or a mobile device. The mobile device includes a mobile phone, a notebook, and a tablet computer. The wearable electronic device includes a smart bracelet, which is not limited in the embodiments of the present disclosure.

[0130] A hinge groove is formed between the first middle frame and the second middle frame, including: a first groove is recessed at the first side of the first middle frame; a second groove is recessed at the second side of the second middle frame; when the first side and the second side are spliced, the first groove and the second groove communicate to form a hinge groove.

[0131] The two rotating structures in the above-mentioned rotating module are respectively fixed on the first middle frame and the second middle frame, including: the two rotating parts of the two rotating sliders in the two rotating structures are respectively fixed on the first middle frame and the second middle frame. The fixing method includes but is not limited to being fixed by screws and nuts.

[0132] It should be noted that when the two rotating structures rotate synchronously, they drive the first middle frame and the second middle frame to rotate synchronously. That is to say, the rotating module can realize the synchronous rotation of the first middle frame and the second middle frame of the terminal device. Moreover, the rotating module in the embodiments of the present disclosure only needs one moving bar to drive the two rotating structures to rotate synchronously, which can simplify the structure of the rotating module, reduce the large fitting clearance caused by the accumulation of assembly tolerances due to complex assembly, improve the synchronous effect of the rotating module, and thus can better realize the folding or unfolding between the first middle frame and the second middle frame of the terminal device.

[0133] In some embodiments, the terminal device includes:

[0134] A folding screen, covering the first middle frame and the second middle frame, and capable of folding at the rotating module.

[0135] In the embodiments of the present disclosure, the folding screen is a flexible screen and can be bent. When the rotating module drives the first middle frame and the second middle frame to rotate synchronously, the terminal device can realize the switching between the unfolded state and the folded state of the folding screen.

[0136] It should be noted that the two rotating structures of the rotating module include a first rotating structure and a second rotating structure. The rotating part of the rotating slider of the first rotating structure is fixedly connected to the first middle frame, and the rotating part of the rotating slider of the second rotating structure is fixedly connected to the second middle frame.

[0137] The process of synchronously rotating the first middle frame and the second middle frame of the terminal device in the embodiments of the present disclosure is as follows: (1) When an external force acts on the first middle frame, it drives the rotating slider of the first rotating structure to rotate; (2) When the rotating slider of the first rotating structure rotates, it drives the gear of the first rotating structure to rotate; (3) When the gear of the first rotating structure rotates, it pushes the moving bar to move in the moving guide groove; (4) When the moving bar moves, it drives the gear of the second rotating structure to rotate; (5) When the gear of the second rotating structure rotates, it drives the rotating slider of the second rotating structure to rotate, thereby realizing the synchronous rotation of the second middle frame driven by the rotating slider of the second rotating structure. In this way, when the terminal device switches between the folded state and the unfolded state, the first middle frame and the second middle frame can be flattened or folded synchronously.
