[0007] The connecting bracket is provided with a slide groove, and an end of the first swing arm away from the rotating shaft is arranged in the slide groove;

[0008] The locking assembly is connected to or abuts against the first swing arm.

[0009] Wherein, when the locking assembly is in the first state, the locking assembly presses the first swing arm and the side wall of the slide slot to limit the relative sliding between the swing arm assembly and the connecting bracket;

[0031] The embodiment of the present application provides a hinge module 100, an electronic device and a control method. Figures 1 to 6 The hinge module 100, electronic device and control method according to the embodiment of the present application are described in detail.

[0032] The following first introduces the hinge module provided in the embodiment of the present application.

[0033] See also Figure 1 , Figure 1 It is a schematic diagram of the split structure of the hinge module of an embodiment of the present application.

[0034] like Figure 1 As shown, the present application provides a hinge module 100, comprising a rotating shaft 10, a swing arm assembly 20, a connecting bracket 30 and a locking assembly 40. The swing arm assembly 20 comprises a first swing arm 21, and the first swing arm 21 is connected to the rotating shaft 10. The connecting bracket 30 is provided with a slide groove 31, and one end of the first swing arm 21 away from the rotating shaft 10 is arranged in the slide groove 31. The locking assembly 40 is connected or abutted with the first swing arm 21, wherein when the locking assembly 40 is in a first state, the locking assembly 40 presses the first swing arm 21 against the side wall of the slide groove 31 to limit the relative sliding between the swing arm assembly 20 and the connecting bracket 30; when the locking assembly 40 is in a second state, the swing arm assembly 20 can be slidably arranged in the slide groove 31.

[0035] In the present application, the hinge module 100 is used as a structural component of the electronic device. The hinge module 100 is connected to the housing in the electronic device, and the housing can be folded or unfolded through the hinge module 100. The connecting bracket 30 is connected to the housing, that is, the hinge module 100 is connected to the housing through the connecting bracket 30, the swing arm assembly 20 is connected to the rotating shaft 10, and the first swing arm 21 is sleeved on the rotating shaft 10 and rotates synchronously with the rotating shaft 10. When an external force acts on the hinge module 100, the first swing arm 21 rotates and the end of the first swing arm 21 away from the rotating shaft 10 slides in the slide groove 31 of the connecting bracket 30.

[0036] In the present application, there is at least one swing arm assembly 20 in the hinge module 100 , and the swing arm assembly 20 is connected to the rotating shaft 10 and the connecting bracket 30 .

[0037] Optionally, the hinge module 100 includes two swing arm assemblies 20, which are arranged on both sides of the rotating shaft 10. Correspondingly, the number of connecting brackets 30 is also two, and each connecting bracket 30 is arranged on the side of the corresponding swing arm assembly 20 away from the rotating shaft 10, and each swing arm assembly 20 at least slides relative to the corresponding connecting bracket 30.

[0038] In some embodiments of the present application, the swing arm assembly 20 includes at least a first swing arm 21, and the first swing arm 21 is connected to the rotating shaft 10 and the connecting bracket 30, wherein the connecting bracket 30 is provided with a slide groove 31, and one end of the first swing arm 21 away from the rotating shaft 10 is arranged in the slide groove 31, so that when the hinge module 100 rotates from the unfolded state to the folded state or from the folded state to the unfolded state, the swing arm assembly 20 can slide in the slide groove 31 of the connecting bracket 30. In this embodiment, the first swing arm is a synchronous swing arm that rotates synchronously with the rotating shaft 10. In other embodiments of the present application, the first swing arm 10 can also be a virtual swing arm, which is not specifically limited here.

[0039] In the present application, the locking assembly 40 has a first state and a second state. When the locking assembly 40 is in the first state, the locking assembly 40 presses the first swing arm 21 against the side wall of the slide slot 31, increases the pressure between the first swing arm 21 and the side wall of the slide slot 31, and limits the relative sliding between the swing arm assembly 20 and the connecting bracket 30 based on the friction force. When the pressure between the first swing arm 21 and the side wall of the slide slot 31 is large enough, it can ensure that the first swing arm 21 and the slide slot 31 are relatively still, completely preventing the sliding between the two, thereby achieving anti-rubbing and hovering. Based on the locking principle of the locking assembly 40, when the locking assembly 40 of the present application is in the first state, the first swing arm 21 cannot slide relative to the connecting bracket 30, so that the first swing arm 21 and the rotating shaft 10 connected to the first swing arm 21 can stop rotating, thereby ensuring that the hinge assembly can achieve reliable hovering and locking at any angle.

[0040] When the locking assembly 40 is in the second state, the locking assembly 40 does not squeeze the first swing arm 21, so that the first swing arm 21 is separated from the side wall of the slide slot 31 to ensure smooth relative sliding between the swing arm assembly 20 and the connecting bracket 30. When the locking assembly 40 is in the second state, the first swing arm 21 and the rotating shaft 10 can continue to rotate, thereby ensuring that the hinge assembly can be freely opened and closed after the hovering and locking states are released.

[0041] In some embodiments of the present application, when the locking assembly 40 is in the first working state, the locking assembly 40 can change its own shape to press the first swing arm 21 of the swing arm assembly 20 against the side wall of the slide groove 31, or the first swing arm 21 can be pressed against the side wall of the slide groove 31 by moving the locking assembly 40.

[0042] In the hinge module 100 provided in the embodiment of the present application, the locking assembly 40 of the hinge module 100 is connected to or abuts against the first swing arm 21, and the locking assembly 40 can be controlled to be in different states to adjust the first swing arm 21 and the side wall of the slide groove 31 to switch between compression and non-compression, thereby controlling the swing arm assembly 20 and the connecting bracket 30 to switch between a relatively static first state and a relatively slidable second state, thereby achieving reliable locking and hovering of the hinge module, avoiding rubbing of the hinge module when it is in a folded state, and effectively improving the user experience.

[0043] The locking assembly 40 of the present application presses the first swing arm 21 and the side wall of the slide groove 31, so that the first swing arm 21 and the slide groove 31 are based on the principle of limiting displacement by increasing friction resistance, so as to limit the relative sliding between the swing arm assembly 20 and the connecting bracket 30, thereby fundamentally solving the defect of rubbing of the hinge module 100.

[0044] In some embodiments of the present application, Figure 1As shown, the hinge module 100 includes two connecting brackets 30, which are located on both sides of the rotating shaft 10 and are symmetrical to each other. Each connecting bracket 30 is provided with a screw hole, and each connecting bracket 30 is fastened to the shell by screws. Therefore, the hinge module 100 is connected to the shell in the electronic device through the connecting bracket 30.

[0045] In some embodiments of the present application, Figure 1 As shown, the swing arm assembly 20 includes two connecting brackets 30 and two swing arm assemblies 20, each connecting bracket 30 is connected to its corresponding swing arm assembly 20, wherein the swing arm assembly 20 also includes a virtual swing arm 23, and the virtual swing arm 23 is connected to the connecting bracket 30 and the rotating shaft 10. A bearing structure is designed at one end of the virtual swing arm 23, which can slide and rotate around the slide groove 31 on the rotating shaft 10. The other end of the virtual swing arm 23 is provided with a pin shaft, which is connected to the shaft hole on the connecting bracket 30. When the outside world applies a force to the hinge module 100, it will drive the first swing arm 21 and the virtual swing arm 23 to rotate. In addition, the connecting bracket 30 can serve as a connecting structure for the motion transmission between the virtual swing arm 23 and the first swing arm 21.

[0046] In some embodiments of the present application, Figure 1 As shown, the swing arm assembly 20 also includes a synchronous gear 24, which cooperates with the gear on the first swing arm 21 to ensure that the first swing arm 21 and the rotating shaft 10 can rotate synchronously.

[0047] In some embodiments of the present application, the hinge module 100 further includes a damping module 50, which provides torque to achieve the hovering function of the hinge module 100. The damping module 50 includes three parts: a compression spring, a cam seat, and a pin shaft, wherein the pin shaft is used to fix the compression spring, the cam seat, and the first swing arm 21 on the rotating shaft 10; the cam on the cam seat engages with the cam on the first swing arm 21, and generates torque together with the compression spring to achieve the hovering of the hinge module 100 at any angle.

[0048] In some embodiments of the present application, the rotating shaft 10 is the base of the entire hinge module 100 and is used for connecting the virtual swing arm 23 , the first swing arm 21 , the synchronous gear 24 and the damping module 50 .

[0049] See also Figure 2 , Figure 2 is a partial structural schematic diagram of a hinge module according to an embodiment of the present application; Figure 3 It is a schematic diagram of the partial structure of the locking assembly in the hinge module of the embodiment of the present application.

[0050] In some embodiments, Figures 1 to 3As shown, the locking assembly 40 includes a first pressing portion 41, a slider 42 and a driving member 43. The first pressing portion 41 is slidably disposed at one end of the slider 42, and the first pressing portion 41 is located between the slider 42 and the side wall of the slide slot 31. The slider 42 is provided with a first guide structure 421, and the first pressing portion 41 is provided with a second guide structure 411 for guiding in cooperation with the first guide structure 421. When the slider 42 moves along the first direction x driven by the driving member 43, the first guide structure 421 causes the first pressing portion 41 to press the first swing arm 21 against the side wall of the slide slot 31 through the second guide structure 411.

[0051] In some embodiments of the present application, the locking assembly 40 includes a first pressing portion 41, a slider 42, and a driving member 43. The first pressing portion 41 is located between the slider 42 and the side wall of the slide slot 31. When the slider 42 moves along the first direction x, the first guide structure 421 cooperates with the second guide structure 411, so that the first pressing portion 41 presses the first swing arm 21 and the side wall of the slide slot 31. The first direction x is parallel to the extension direction of the side wall of the slide slot 31.

[0052] In some embodiments of the present application, when the slider 42 moves along the first direction x under the push of the driving member 43, the slider 42 can slide on the bottom of the slide groove 31, and the slider 42 can also slide on the other side wall of the slide groove 31 away from the first clamping portion 41. It is only necessary to meet the condition that the first clamping portion 41 can clamp the first swing arm 21 and the side wall of the slide groove 31 when the slider 42 moves along the first direction x.

[0053] Optionally, the first clamping portion 41 and the slider 42 are separately nested and cooperated. When the slider 42 moves along the first direction x, the first guide structure 421 cooperates with the second guide structure 411 to make the first clamping portion 41 move along the second direction y, and the second direction y intersects or is perpendicular to the first direction x, wherein the first direction x is the extension direction of the slide groove 31. Such an arrangement enables the first clamping portion 41 to quickly clamp the first swing arm 21 and the side wall of the slide groove 31 under the premise that the slider 42 moves a short distance along the first direction x.

[0054] Exemplarily, the slider 42 is provided with a first guide structure 421 which is a screw, and the first clamping portion 41 is provided with a second guide structure 411 which is a threaded sleeve or a threaded hole sleeved on the screw, and the screw is threadedly matched with the threaded sleeve or the threaded hole. When the slider 42 moves along the first direction x under the push of the driving member 43, the screw is screwed out of the threaded sleeve or the threaded hole, so that the first clamping portion 41 moves away from the slider 42, that is, the first clamping portion 41 presses the first swing arm 21 and the side wall of the slide groove 31.

[0055] Exemplarily, a fixing pin is provided on the slider 42, and a guide groove or a guide opening is provided on the first clamping portion 41. The fixing pin is arranged in the guide groove or the guide opening and is movable. When the slider 42 moves along the first direction x under the push of the driving member 43, the fixing pin moves along the guide groove or the guide opening, so that the first clamping portion 41 moves away from the slider 42, that is, the first clamping portion 41 clamps the first swing arm 21 and the side wall of the slide groove 31.

[0056] In these optional embodiments, the first guide structure 421 of the slider 42 cooperates with the second guide structure 411 of the first pressing portion 41, and when the slider 42 moves along the first direction x under the push of the driving member 43, the first guide structure 421 causes the first pressing portion 41 to press the first swing arm 21 against the side wall of the slide slot 31 through the second guide structure 411, so as to limit the relative sliding between the swing arm assembly 20 and the connecting bracket 30. When the swing arm assembly 20 and the connecting bracket 30 slide relative to each other, the first guide structure 421 does not need to press the first swing arm 21 against the side wall of the slide slot 31, so as not to affect the continued sliding between the swing arm assembly 20 and the connecting bracket 30. Moreover, the locking assembly 40 occupies a relatively small internal space of the hinge module 100, further improving the overall layout compactness of the hinge module 100, and does not affect the overall structure of the hinge module 100.

[0057] In some embodiments, Figure 1 and Figure 2 As shown, the swing arm assembly 20 further includes a second swing arm 22, the first swing arm 21 and the second swing arm 22 are both connected to the rotating shaft 10, one end of the second swing arm 22 away from the rotating shaft 10 is disposed in the slide slot 31, and the locking assembly 40 is disposed between the first swing arm 21 and the second swing arm 22. The slide slot 31 has a first side wall 311 and a second side wall 312. When the locking assembly 40 is in the first state, the locking assembly 40 presses the first swing arm 21 against the first side wall 311 and presses the second swing arm 22 against the second side wall 312 to limit the relative sliding between the swing arm assembly 20 and the connecting bracket 30.

[0058] In some embodiments of the present application, the swing arm assembly 20 includes a first swing arm 21 and a second swing arm 22. The first swing arm 21 and the second swing arm 22 are two independent structures. The first swing arm 21 and the second swing arm 22 are located on the same side of the rotating shaft 10 and are respectively slidably connected to the slide groove 31 of the connecting bracket 30. The slide groove 31 has a first side wall 311 and a second side wall 312. The first swing arm 21 is located at the first side wall 311, and the second swing arm 22 is located at the second side wall 312. The locking assembly 40 is arranged between the first swing arm 21 and the second swing arm 22. The locking assembly 40 can realize synchronous control of the first swing arm 21 and the second swing arm 22, so as to press the first swing arm 21 against the first side wall 311, and press the second swing arm 22 against the second side wall 312.

[0059] In some embodiments of the present application, the locking assembly 40 moves between the first swing arm 21 and the second swing arm 22, thereby pressing the first swing arm 21 against the first side wall 311 and pressing the second swing arm 22 against the second side wall 312 to limit the relative sliding between the swing arm assembly 20 and the connecting bracket 30.

[0060] Exemplarily, the locking assembly 40 includes a movable groove and two movable blocks, and the two movable blocks are movably arranged in the movable groove. When the two movable blocks move to the first position, that is, when the locking assembly 40 is in the first state, the two movable blocks abut against the first swing arm 21 and the second swing arm 22 respectively, and press the first swing arm 21 against the first side wall 311 and the second swing arm 22 against the second side wall 312. When the two movable blocks move to the second position, the movable blocks are separated from the first swing arm 21 and the second swing arm 22 or do not press the first swing arm 21 and the second swing arm 22.

[0061] Exemplarily, the locking assembly 40 is a retractable member, which can be retracted and extended between the first swing arm 21 and the second swing arm 22, wherein, when the retractable member is extended, the retractable member abuts against the first swing arm 21 and the second swing arm 22, and presses the first swing arm 21 against the first side wall 311 and the second swing arm 22 against the second side wall 312; when the retractable member is retracted, the retractable member is separated from the first swing arm 21 and the second swing arm 22 or does not squeeze the first swing arm 21 and the second swing arm 22.

[0062] Optionally, the first swing arm 21 and the second swing arm 22 are both synchronous swing arms.

[0063] In these optional embodiments, the swing arm assembly 20 is designed to be a first swing arm 21 and a second swing arm 22 of a split structure, so that a locking assembly 40 is arranged between the first swing arm 21 and the second swing arm 22, and it can be ensured that the first swing arm 21 and the second swing arm 22 can be pressed in the slide groove 31 at the same time. When the hinge module 100 is in a suspended state, the locking assembly 40 presses the first swing arm 21 against the first side wall 311 and the second swing arm 22 against the second side wall 312 to limit the relative sliding between the swing arm assembly 20 and the connecting bracket 30, thereby reducing the relative movement between the swing arm assembly 20 and the connecting bracket 30, and reducing the defect of rubbing of the hinge module 100.

[0064] In some embodiments, Figure 2 and Figure 3As shown, the locking assembly 40 includes a first pressing portion 41, a second pressing portion 44 and a driving member 43, and the driving member 43 is used to drive the first pressing portion 41 and the second pressing portion 44 to move closer to each other or away from each other. In the process of switching the locking assembly 40 from the second state to the first state, the driving member 43 drives the first pressing portion 41 and the second pressing portion 44 to move away from each other, the first pressing portion 41 presses the first swing arm 21 and the first side wall 311, and the second pressing portion 44 presses the second swing arm 22 and the second side wall 312. In the process of switching the locking assembly 40 from the first state to the second state, the driving member 43 drives the first pressing portion 41 and the second pressing portion 44 to move closer to each other.

[0065] In some embodiments of the present application, the locking assembly 40 includes a first clamping portion 41, a second clamping portion 44 and a driving member 43. The first clamping portion 41 and the second clamping portion 44 are arranged between the first swing arm 21 and the second swing arm 22. The driving member 43 can drive the first clamping portion 41 and the second clamping portion 44 to realize the movement of the first clamping portion 41 and the second clamping portion between the first swing arm 21 and the second swing arm 22. It can be understood that the first clamping portion 41 and the second clamping portion 44 are moved to different positions by the driving of the driving member 43, so as to be in a state of being away from or close to each other.

[0066] Exemplarily, the first clamping portion 41 is a first magnet, the second clamping portion 44 is a second magnet, and the driving member 43 is a magnetic induction coil. When the locking assembly 40 is in the first state, the magnetic induction coil is adjusted so that the first magnet and the second magnet are to have the same magnetic poles. Based on the repulsion of like poles, the first magnet and the second magnet repel each other and move away from each other. The first magnet squeezes the first swing arm 21 to press the first swing arm 21 and the first side wall 311, and the second magnet squeezes the second swing arm 22 to press the second swing arm 22 and the second side wall 312. When the locking assembly 40 is in the second state, the magnetic induction coil is adjusted so that the first magnet and the second magnet are to have opposite magnetic poles. The first magnet and the second magnet attract each other and approach each other.

[0067] Exemplarily, the first clamping portion 41 is a first moving block, the second clamping portion 44 is a second moving block, and the driving member 43 is a driving motor. When the locking assembly 40 is in the first state, the driving motor drives the first moving block and the second moving block to move in directions away from each other, and the first moving block squeezes the first swing arm 21 to press the first swing arm 21 and the first side wall 311, and the second moving block squeezes the second swing arm 22 to press the second swing arm 22 and the second side wall 312. When the locking assembly 40 is in the second state, the driving motor drives the first moving block and the second moving block to move in a direction approaching each other.

[0068] Optionally, the moving directions of the first pressing portion 41 and the second pressing portion 44 are parallel to the direction of the shortest path between the first swing arm 21 and the second swing arm 22 .

[0069] In these optional embodiments, the driving member 43 can drive the first clamping portion 41 and the second clamping portion 44 to move closer to or away from each other, and the driving member 43 can continue to work to continuously control the states of the first clamping portion 41 and the second clamping portion 44, thereby ensuring the reliability and uniformity of the clamping of the first swing arm 21 and the first side wall 311 and the clamping of the second swing arm 22 and the second side wall 312.

[0070] In some embodiments, Figure 2 and Figure 3 As shown, the locking assembly 40 further includes a slider 42, the slider 42 has a first end and a second end opposite to each other, the first pressing portion 41 is slidably disposed at the first end of the slider 42, and the second pressing portion 44 is slidably disposed at the second end of the slider 42. A first guide structure 421 is disposed on the slider 42, and a second guide structure 411 for guiding in cooperation with the first guide structure 421 is disposed on the first pressing portion 41 and the second pressing portion 44. When the slider 42 moves along the first direction x driven by the driving member 43, the first guide structure 421 makes the first pressing portion 41 and the second pressing portion 44 approach or move away from each other through the second guide structure 411.

[0071] In some embodiments of the present application, the driving member 43 can directly drive the slider 42 to move in the first direction x. When the slider 42 moves along the first direction x, the first guide structure 421 cooperates with the second guide structure 411 to make the first clamping portion 41 and the second clamping portion 44 approach each other or move away from each other to limit the relative sliding between the swing arm assembly 20 and the connecting bracket 30.

[0072] Optionally, the slider 42 includes a first end and a second end, the first end and the second end are arranged opposite to each other, the first end of the slider 42 is provided with a first guide structure 421, the second end of the slider 42 is also provided with a first guide structure 421, and the first pressing portion 41 and the second pressing portion 44 arranged on both sides of the slider 42 are both provided with a second guide structure 411. When the slider 42 moves along the first direction x and away from the rotation axis 10, the first guide structure 421 cooperates with the second guide structure 411, so that the first pressing portion 41 moves away from the slider 42 and toward the first swing arm 21. In the case where the slider 42 moves along the first direction x and close to the direction of the rotating shaft 10, the first guiding structure 421 cooperates with the second guiding structure 411 to make the first clamping portion 41 move away from the first swing arm 21 and toward the slider 42, and the second clamping portion 44 moves away from the second swing arm 22 and toward the slider 42, that is, the first clamping portion 41 and the second clamping portion 44 move close to each other.

[0073] Optionally, the first pressing portion 41 and the second pressing portion 44 move along the second direction y between the first swing arm 21 and the second swing arm 22. The second direction y intersects or is perpendicular to the first direction x.

[0074] In these optional embodiments, the slider 42 is driven to move along the first direction x by the driving member 43, so that the first guide structure 421 at the first end of the slider 42 cooperates with the second guide structure 411 of the first swing arm 21, and the first guide structure 421 at the second end of the slider 42 cooperates with the second guide structure 411 of the second swing arm 22, so as to realize that the first clamping portion 41 and the second clamping portion 44 approach each other or move away from each other, and the first clamping portion 41 and the second clamping portion 44 move independently of each other, which can reduce the mutual influence between the first clamping portion 41 and the second clamping portion 44 during the movement, thereby effectively ensuring the anti-rubbing effect of the hinge module 100.

[0075] In some embodiments, the first guide structure 421 is a fixed pin fixed to the slider 42. The second guide structure 411 includes a guide groove or a guide opening, and the extension direction of the guide groove or the guide opening forms a non-zero angle with the first direction x.

[0076] In some embodiments of the present application, the second guide structure 411 includes a guide groove or a guide opening, so that the fixing pin can move in the guide groove or the guide opening. Moreover, a non-zero angle is formed between the extension direction of the guide groove or the guide opening and the first direction x, so that when the slider 42 reciprocates along the first direction x, the first pressing portion 41 and the second pressing portion 44 approach or move away from each other.

[0077] Exemplarily, during the movement of the slider 42 along the first direction x away from the rotating shaft 10, the fixing pin moves with the slider 42 and the fixing pin moves in the guide groove or the guide opening, so that the first clamping portion 41 and the second clamping portion 44 move toward the side wall close to the slide groove 31, that is, the first clamping portion 41 and the second clamping portion 44 move away from each other, and then the first clamping portion 41 squeezes the first side wall 311 and the second clamping portion 44 squeezes the second side wall 312.

[0078] Exemplarily, during the movement of the slider 42 along the first direction x toward the rotating shaft 10, the fixing pin moves with the slider 42 and moves in the guide groove or the guide opening, so that the first clamping portion 41 and the second clamping portion 44 move toward the side wall away from the slide groove 31, that is, the first clamping portion 41 and the second clamping portion 44 move away from each other.

[0079] Optionally, the slider 42 is provided with at least two first guide structures 421 .

[0080] Exemplarily, the slider 42 is provided with at least two fixing pins, and the arrangement direction of the at least two fixing pins is the same as the extension direction of the guide groove or the guide opening on the slider 42, that is, they are arranged at a non-zero angle with the first direction x.

[0081] Optionally, a fixing pin and a matching pin hole are provided on the slider 42 , and the fixing pin passes through the pin hole and extends along both ends and protrudes from the slider 42 .

[0082] Optionally, a non-zero angle is formed between the extension direction of the guide groove or the guide opening and the first direction x, and the angle is less than 90°. Further optionally, the angle is 20° to 50°. When the angle formed between the extension direction of the guide groove or the guide opening and the first direction x is large, the first pressing portion 41 can be accelerated to squeeze the first swing arm 21 and the second pressing portion 44 can be accelerated to squeeze the second swing arm 22.

[0083] In these optional embodiments, when the slider 42 moves along the first direction x under the push of the driving member 43, the fixing pin cooperates with the guide groove or the guide opening to achieve the first clamping portion 41 and the second clamping portion 44 approaching or moving away from each other, and the structures of the upper components are simple and easy to manufacture and industrially produce.

[0084] In some embodiments, the first pressing portion 41 has a connecting groove, and the first pressing portion 41 is sleeved on the first end of the sliding block 42 through the connecting groove.

[0085] Optionally, the slider 42 is a wedge-shaped structure, and a first end of the slider 42 has a protrusion, which cooperates with a connecting groove of the first pressing portion 41 to form a nested structure.

[0086] Optionally, the first pressing portion 41 has a connecting groove, and a groove wall of the connecting groove is provided with a second guide structure 411. More optionally, the second guide structure 411 includes a guide groove or a guide opening.

[0087] In these optional embodiments, the connecting groove of the first clamping portion 41 and the first end of the slider 42 form a nested structure, which can provide a guide for the movement of the slider 42 along the first direction x. Moreover, the nested cooperation between the first clamping portion 41 and the slider 42 can also save the space occupied by the locking assembly 40, thereby further improving the overall layout tightness of the hinge module 100.

[0088] In some embodiments, the locking assembly 40 is disposed in the slide groove 31 , and the bottom surface of the slide groove 31 is provided with a first limit stopper 32 and a second limit stopper 33 , and the slider 42 moves between the first limit stopper 32 and the second limit stopper 33 under the push of the driving member 43 .

[0089] In some embodiments of the present application, the first limit stopper 32 is selected from a protrusion or a protruding plate, and is fixedly connected to the connecting bracket 30 .

[0090] In some embodiments of the present application, the second limit stopper 33 is selected from a protrusion or a protruding plate, and is fixedly connected to the connecting bracket 30 .

[0091] Optionally, the gap between the first limit stopper 32 and the second limit stopper 33 is equal to the length of the first pressing portion 41 along the first direction x and / or the gap between the first limit stopper 32 and the second limit stopper 33 is equal to the length of the second pressing portion 44 along the first direction x.

[0092] In these optional embodiments, the slider 42 moves between the first limit stopper 32 and the second limit stopper 33, thereby planning the movement path of the first pressing portion 41 and the second pressing portion 44. In addition, the first limit stopper 32 and the second limit stopper 33, 33 can also limit the first pressing portion 41 and the second pressing portion 44 from moving along the first direction x, thereby effectively preventing the first pressing portion 41 and the second pressing portion 44 from driving the swing arm assembly 20 to move along the first direction x.

[0093] In some embodiments, Figure 2 and Figure 3 As shown, the driving member 43 includes a pushing structure 431 and a reset structure 432. The pushing structure 431 and the reset structure 432 are respectively arranged on opposite sides of the slider 42 along the side wall extension direction of the slide groove 31. The pushing structure 431 is connected or abutted with the slider 42, and the reset structure 432 is connected or abutted with the slider 42.

[0094] In some embodiments of the present application, the pushing structure 431 applies a pushing force to the slider 42 so that the slider 42 moves in the direction of the reset structure 432, and the reset structure 432 applies a force to the slider 42 so that the slider 42 moves in the direction of the pushing structure 431. When the pushing structure 431 does not do work on the slider 42 or the pushing force applied by the pushing structure 431 to the slider 42 is less than the force of the reset structure 432, the reset structure 432 causes the slider 42 to move in the direction of the pushing structure 431; when the pushing structure 431 does work on the slider 42 or the pushing force applied by the pushing structure 431 to the slider 42 is greater than the force of the reset structure 432, the pushing structure 431 causes the slider 42 to move in the direction of the reset structure 432, thereby realizing reciprocating motion of the slider 42 in the first direction x.

[0095] In these optional embodiments, the pushing structure 431 and the reset structure 432 are arranged on both sides of the slider 42. The pushing structure 431 and the reset structure 432 work together to realize the reciprocating motion of the slider 42 in the first direction x (that is, the extension direction of the side wall of the slide groove 31), thereby limiting the relative sliding between the swing arm assembly 20 and the connecting bracket 30 or continuing the relative sliding between the swing arm assembly 20 and the connecting bracket 30, thereby realizing the adjustment of the hinge module 100 at any angle.

[0096] In some embodiments, the pushing structure 431 includes a driving part 4311 and a rotating part 4312. The rotating part 4312 abuts against the slider 42. The rotating part 4312 includes a cam or an eccentric cylindrical wheel. The driving part 4311 drives the cam or the eccentric cylindrical wheel to rotate to push the slider 42 to move through the cam or the eccentric cylindrical wheel.

[0097] In some embodiments of the present application, the pushing structure 431 includes a driving part 4311 and a rotating part 4312. The rotating part 4312 abuts against the slider 42.

[0098] In these optional embodiments, the rotating portion 4312 includes a cam or an eccentric cylindrical wheel. Through the design of the shape of the rotating portion 4312, when the driving portion 4311 drives the cam or the eccentric cylindrical wheel to rotate, the difference in the pushing force of the pushing structure 431 on the slider 42 can realize the reciprocating motion of the slider 42 along the first direction x. Moreover, the design of the above-mentioned rotating portion 4312 can also simplify the structure of the locking assembly 40.

[0099] Combined with reference Figure 4 , Figure 4 It is a structural schematic diagram of the hinge module of an embodiment of the present application.

[0100] In some embodiments, Figure 4 As shown, the locking assembly 40 includes two first clamping parts 41, two second clamping parts 44, two sliders 42 and a driving member 43, the driving member 43 includes a driving part 4311 and a rotating part 4312, the two sliders 42 are arranged on both sides of the rotating part 4312, and the rotating part 4312 abuts against the slider 42, the first end of the slider 42 is provided with a first clamping part 41 and the second end is provided with a second clamping part 44, the rotating part 4312 includes a cam or an eccentric cylindrical wheel, and the driving part 4311 drives the cam or the eccentric cylindrical wheel to rotate so as to push the slider 42 to move through the cam or the eccentric cylindrical wheel.

[0101] In these optional embodiments, a first clamping portion 41, a second clamping portion 44 and a sliding block 42 are provided on both sides of the driving member 43. The provision of the two first clamping portions 41 can further increase the degree of clamping between the first swing arm 21 and the first side wall 311, and the provision of the two second clamping portions 44 can also further increase the degree of clamping between the second swing arm 22 and the second side wall 312, thereby further increasing the friction resistance between the swing arm assembly 20 and the slide groove 31, thereby more effectively limiting the relative sliding between the swing arm assembly 20 and the connecting bracket 30.

[0102] In some embodiments, Figure 2 and Figure 3 As shown, the pushing structure 431 also includes a central axis 4313, and a shaft hole is provided on the connecting bracket 30, and the central axis 4313 is rotatably arranged in the shaft hole. The driving part 4311 includes a driving motor 4311a and a gear 4311b, wherein the driving motor 4311a is arranged on a side of the connecting bracket 30 away from the special-shaped disk, the driving motor 4311a is connected to the connecting bracket 30, and the gear 4311b is connected to the driving motor 4311a and the central axis 4313, and the driving motor 4311a drives the central axis 4313 to rotate through the gear 4311b.

[0103] In some embodiments of the present application, the driving motor 4311a is connected to the gear 4311b, the gear 4311b is connected to the central axis 4313, the driving motor 4311a drives the gear 4311b to rotate, the rotating gear 4311b drives the central axis 4313 to rotate, the central axis 4313 is connected to the rotating part 4312, and the central axis 4313 can drive the turntable rotating part 4312 to rotate.

[0104] Optionally, the connecting bracket 30 is provided with a through hole, and the central axis 4313 passes through the through hole and is rotatably connected in the through hole.

[0105] Optionally, the driving portion 4311 and the rotating portion 4312 are respectively arranged at two ends of the central axis 4313 .

[0106] Exemplarily, the middle shaft 4313 is connected to the eccentric cylindrical wheel and drives the eccentric cylindrical wheel to rotate. The driving motor 4311a drives the eccentric cylindrical wheel to rotate through the gear 4311b and the middle shaft 4313. During the rotation of the eccentric cylindrical wheel, the difference in distance between the wheel edge of the eccentric cylindrical wheel and the abutment point of the sliding block and the middle shaft 4313 is used to adjust the movement of the slider 42, thereby controlling the degree to which the first clamping part 41 squeezes the first swing arm 21 and the degree to which the second clamping part 44 squeezes the second swing arm 22. When the eccentric cylindrical wheel rotates to the point where the distance between the abutment point and the middle shaft 4313 is the largest, the first clamping part 41 and the second clamping part 44 move away from each other, the first clamping part 41 exerts the largest squeezing force on the first swing arm 21, and the second clamping part 44 exerts the largest squeezing force on the second swing arm 22, thereby utilizing friction to limit the relative sliding between the swing arm assembly 20 and the connecting bracket 30.

[0107] In these optional embodiments, the driving portion 4311 and the rotating portion 4312 are separated by the design of the central axis 4313, which can reduce the influence of the driving portion 4311 on the rotating portion 4312. Moreover, the driving portion 4311 and the rotating portion 4312 do not need to be designed on the same side of the connecting bracket 30, so the structure of the locking assembly 40 can be reasonably planned.

[0108] In some embodiments, the reset structure 432 is an elastic member, the locking assembly 40 is disposed in the slide groove 31, the bottom surface of the slide groove 31 is provided with a first limit stopper 32, one end of the elastic member is connected to the slider 42, and the other end of the elastic member is connected to the first limit stopper 32.

[0109] In some embodiments of the present application, the elastic member can be selected from one of a linear spring, a torsion spring, a spring, a solid elastic rubber, a porous elastic rubber, a solid elastic plastic, a porous elastic plastic, a memory metal and a magnetic component.

[0110] In these optional embodiments, when the driving part 4311 drives the slider 42 to move away from the elastic member, the elastic member is in a tension state, and based on the elastic force (tension) after the elastic member is stretched, the slider 42 is driven to move in a direction away from the driving part 4311; when the driving part 4311 drives the slider 42 to move close to the elastic member, the elastic member is in a contraction deformation due to the external load, and based on the elastic force (thrust) after the elastic member is contracted, the slider 42 is driven to move in a direction close to the driving part 4311, thereby realizing the reciprocating motion of the slider 42 along the first direction x. The setting of the elastic member can also improve the buffering of the slider 42 to prevent the slider 42 from rigidly colliding with the first limit stopper 32.

[0111] Combined with reference Figure 5 and Figure 6 , Figure 5 is a structural schematic diagram of a slider in a hinge module of an embodiment of the present application; Figure 6 It is a schematic diagram of the partial structure of the hinge module of an embodiment of the present application.

A limit groove 423 is provided at one end of the slider 42 close to the second limit stopper 33, and the limit groove 423 is located on the center line b of the slide slot 31.

[0115] Optionally, the line connecting the first guide structure 421 located at the first end of the slider 42 and the first guide structure 421 located at the second end of the slider 42 has a first perpendicular bisector, the line connecting the second guide structure 411 on the first clamping portion 41 and the second guide structure 411 on the second clamping portion 44 has a second perpendicular bisector, the first perpendicular bisector is parallel to the second perpendicular bisector, and the center line c of the limit groove 423 and the center line b of the slide groove 31 are both located on the plane determined by the first perpendicular bisector and the second perpendicular bisector.

[0120] See also Figure 7 , Figure 7 It is a flow chart of the control method of an embodiment of the present application.

[0121] like Figure 7 As shown, the control method provided in the embodiment of the present application is applied to the electronic device provided in the above embodiment, and the method includes:

[0122] S10, the locking assembly 40 receives a state control signal;

[0123] S21, when the state control signal is the first control signal, in response to the first control signal, the locking assembly 40 is controlled to be in the first state, in which the locking assembly 40 presses the first swing arm 21 and the side wall of the slide groove 31 to limit the relative sliding between the swing arm assembly 20 and the connecting bracket 30;

[0124] S22. When the state control signal is the second control signal, in response to the second control signal, the locking assembly 40 is controlled to be in the second state. In the second state, the swing arm assembly 20 is slidably disposed in the slide groove 31.

[0125] Exemplarily, the electronic device outputs a state control signal to the drive motor 4311a in the locking assembly 40, and the state control signal is an angle signal of the hinge module 100 at a position between folding 0° and flattening 180°.

[0126] When the state control signal is the first control signal, the driving motor 4311a receives the first control signal and responds to the first control signal. The driving motor 4311a drives the gear 4311b to rotate 180° counterclockwise, and the gear 4311b drives the central axis 4313 to rotate. The eccentric cylindrical wheel at the other end of the central axis 4313 rotates 180° counterclockwise with the central axis 4313. During the rotation of the eccentric cylindrical wheel, the distance from the rotation center of the eccentric wheel to the abutting edge of the slider 42 increases continuously, and the force of the eccentric cylindrical wheel on the slider 42 gradually increases, and the slider 42 moves along the first direction x. The slider 42 moves in the direction away from the eccentric cylindrical wheel. During the movement of the slider 42, the fixing pin at one end of the slider 42 moves along the guide groove of the first clamping part 41, and the fixing pin at the other end of the slider 42 moves along the guide groove of the second clamping part 44. The first clamping part 41 and the second clamping part 44 move away from each other in the direction away from the slider 42. The first clamping part 41 presses the first swing arm 21 and the first side wall 311, and the second clamping part 44 presses the second swing arm 22 and the second side wall 312 to limit the relative sliding between the swing arm assembly 20 and the connecting bracket 30, and the hinge module 100 is in a suspended state.

[0127] Exemplarily, the electronic device outputs a state control signal to the drive motor 4311a in the locking assembly 40, and the state control signal is an angle signal that the hinge module 100 is at a position between folding 0° and flattening 180°.

The drive motor 4311a drives the gear 4311b to rotate 180° clockwise, and the gear 4311b drives the central axis 4313 to rotate. The eccentric cylindrical wheel at the other end of the central axis 4313 rotates 180° clockwise with the central axis 4313. During the rotation of the eccentric cylindrical wheel, since the distance from the rotation center of the eccentric wheel to the abutment edge of the slider 42 is continuously reduced, the eccentric cylindrical wheel is The force gradually weakens, and the slider 42 is subjected to the reverse elastic force applied by the elastic member in the accommodating portion 422 of the slider 42, so that the slider 42 moves along the first direction x towards the direction close to the eccentric cylindrical wheel. During the movement of the slider 42, the fixing pin at one end of the slider 42 moves along the guide groove of the first clamping portion 41, and the fixing pin at the other end of the slider 42 moves along the guide groove of the second clamping portion 44. The first clamping portion 41 and the second clamping portion 44 move towards each other in the direction close to the slider 42. The first clamping portion 41 reduces the pressure on the first swing arm 21 and the first side wall 311, and the second clamping portion 44 reduces the pressure on the second swing arm 22 and the second side wall 312. The swing arm assembly 20 and the connecting bracket 30 can continue to slide relative to each other, and the hinge module 100 rotates.
