Description

Technical Field

[0001] This application relates to the field of hinge folding technology, and particularly to hinge mechanisms and electronic devices. Background Technology

[0002] Electronic devices are products that meet users' functional needs, and they are generally foldable to make them easy for users to store.

[0003] In related technologies, electronic devices generally include a hinge mechanism, which achieves folding and unfolding through two relatively rotatable parts. Because the two parts require a mechanism to synchronize their rotation, the structure is relatively complex. Utility Model Content

[0004] In view of this, this application provides a hinge mechanism and an electronic device to simplify their structure.

[0005] Specifically, the following technical solutions are included:

[0006] A first aspect of this application provides a hinge mechanism, the hinge mechanism comprising a first rotating assembly, a second rotating assembly, and an elastic element, wherein...

[0007] The elastic element is located between one side of the first rotating assembly and one side of the second rotating assembly, and is drivingly connected to the first rotating assembly and the second rotating assembly;

[0008] When either the first rotating assembly or the second rotating assembly rotates, the elastic element can undergo elastic deformation to drive the other one to rotate.

[0009] In some possible implementations, the elastic element includes a first elastic portion and a second elastic portion, wherein the first elastic portion is drive-connected to the first rotating assembly, and the second elastic portion is drive-connected to the second rotating assembly.

[0010] With the above arrangement, the first elastic part can undergo elastic deformation when the first rotating assembly rotates, and this elastic deformation can drive the second rotating assembly to rotate. Similarly, the second elastic part can undergo elastic deformation when the second rotating assembly rotates, and this elastic deformation can drive the second rotating assembly to rotate. Through the first and second elastic parts, the elastic element can receive the forces from the first and second rotating assemblies and undergo elastic deformation, thereby causing them to rotate synchronously.

[0011] In some possible implementations, the first elastic portion includes a first deformation groove, the first rotating assembly includes a first tooth, the first tooth is rotatable, and the first tooth is used to extend into the first deformation groove and abut against the wall of the first deformation groove to cause elastic deformation of the elastic element; and / or, the second elastic portion includes a second deformation groove, the second rotating assembly includes a second tooth, the second tooth is rotatable, and the second tooth is used to extend into the second deformation groove and abut against the wall of the second deformation groove to cause elastic deformation of the elastic element.

[0012] With the above arrangement, the elastic force generated by the compression of the first deformation groove by the first gear tooth and the elastic force generated by the compression of the second deformation groove by the second gear tooth can interact with each other. For example, the elastic force generated by the first deformation groove can cause the wall of the second deformation groove to abut against the second gear tooth, thereby driving the second gear tooth to rotate and realizing the synchronous rotation of the first rotating component and the second rotating component. The reverse is also true, which will not be elaborated here.

[0013] In some possible implementations, the first elastic portion includes a first mating plate and a second mating plate, one side of the first mating plate is connected to one side of the second mating plate, and the other side of the first mating plate and the other side of the second mating plate form an opening of the first deformation groove, the opening of the first deformation groove facing the side where the first gear tooth of the first rotating assembly is located; and / or, the second elastic portion includes a third mating plate and a fourth mating plate, one side of the third mating plate is connected to one side of the fourth mating plate, and the other side of the third mating plate and the other side of the fourth mating plate form an opening of the second deformation groove, the opening of the second deformation groove facing the side where the second gear tooth of the second rotating assembly is located.

[0014] With the above arrangement, the cooperation between the first mating plate and the second mating plate can cause the elastic element to undergo elastic deformation, thereby causing the third mating plate and the fourth mating plate to press against the second gear tooth, thus achieving synchronous rotation of the first rotating assembly and the second rotating assembly.

[0015] In some possible implementations, the elastic element includes a force-transmitting portion located between the first elastic portion and the second elastic portion, one end of the force-transmitting portion being connected to the side of the first elastic portion facing the second elastic portion, and the other end of the force-transmitting portion being connected to the side of the second elastic portion facing the first elastic portion.

[0016] With the above arrangement, the force transmission part can transmit the elastic force generated by the first elastic part and the second elastic part. This transmission effect is conducive to the same degree of elastic deformation between the first elastic part and the second elastic part, so that the first rotating component and the second rotating component rotate to the same degree, achieving a synchronous effect.

[0017] In some possible implementations, there are multiple first elastic parts, multiple second elastic parts, and multiple force transmission parts. The multiple first elastic parts, multiple second elastic parts, and multiple force transmission parts are arranged along a first direction. The first elastic part includes a first deformation groove, the second elastic part includes a second deformation groove, and there is a compression cavity between two adjacent force transmission parts. The compression cavity is located between the first deformation groove and the second deformation groove that are opposite to each other.

[0018] With the above arrangement, after each first elastic part and each second elastic part undergoes elastic deformation, on the one hand, they can transmit force to each other through the force transmission part; on the other hand, after elastic deformation, the adjacent structure can continue to abut against the first rotating component or the second rotating component, thereby continuing to undergo elastic deformation.

[0019] In some possible implementations, the compression chamber extends through the opposite ends of the elastic member along the extension direction of the rotation axis of the first rotating assembly.

[0020] With the above arrangement, this shape makes the extrusion cavity tend to deform under the driving action of the first elastic part and the second elastic part, which is beneficial for the extrusion cavity to rotate synchronously by undergoing elastic deformation.

[0021] In some possible implementations, the force transmission part includes a guide part located at the edge of the opening of the extrusion chamber.

[0022] With the above arrangement, each extrusion chamber can undergo elastic deformation in sequence under the guidance of the guide part, and the first deformation groove and the second deformation groove can undergo elastic deformation synchronously. This is beneficial for the first elastic part and the second elastic part to rotate synchronously, so that the first rotating assembly and the second rotating assembly can rotate.

[0023] A second aspect of this application provides an electronic device that includes a hinge mechanism as described in the above technical solutions.

[0024] In some possible implementations, the electronic device includes a first mid-frame and a second mid-frame, wherein the first rotating component is tractively connected to the first mid-frame and the second rotating component is tractively connected to the second mid-frame.

[0025] By rotating the first and second middle frames, electronic devices can be in an unfolded or folded state, which makes it easier for users to store electronic devices.

[0026] In some possible implementations, the electronic device includes a first magnetic clasp and a second magnetic clasp, the first magnetic clasp being located in the first middle frame and the second magnetic clasp being located in the second middle frame. The first rotating assembly and the second rotating assembly can be rotated to make the first magnetic clasp and the second magnetic clasp be positioned opposite each other. When the first rotating assembly and the second rotating assembly are rotated to a folded position, the elastic element is compressed.

[0027] With the above arrangement, when the first rotating assembly and the second rotating assembly rotate to the folded position, the elastic element is compressed, which makes it easy for both to rotate to the unfolded position. By arranging the first magnetic element and the second magnetic element, both can maintain the folded state through magnetic attraction when they are in the folded position.

[0028] The beneficial effects of the technical solution provided in this application include at least the following: the first rotating component and the second rotating component can be folded and unfolded through relative rotation. The elastic element, through elastic deformation, can apply a force to the other when one of the first and second rotating components rotates, allowing them to rotate synchronously. Furthermore, the generated force can also serve as a source of damping for the user and assist the user in driving the first and second rotating components to rotate. By achieving synchronous rotation, providing damping for the user, and assisting the user in driving the first and second rotating components to rotate through the elastic element, the structure of this application is simplified.

Detailed Implementation

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0046] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0047] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0048] The first aspect of this application provides a hinge mechanism, such as Figure 1 and Figure 2 As shown, the hinge mechanism includes a first rotating assembly 1, a second rotating assembly 2, and an elastic element 3, wherein,

[0049] The elastic element 3 is located between one side of the first rotating assembly 1 and one side of the second rotating assembly 2, and is connected to the first rotating assembly 1 and the second rotating assembly 2 in a transmission manner;

[0050] When either the first rotating assembly 1 or the second rotating assembly 2 rotates, the elastic element 3 can undergo elastic deformation to drive the other one to rotate.

[0051] With the above arrangement, the first rotating assembly 1 and the second rotating assembly 2 can be folded and unfolded through relative rotation. The elastic element 3, through elastic deformation, can apply a force to the other when one of the first rotating assembly 1 and the second rotating assembly 2 rotates, allowing them to rotate synchronously. Furthermore, the generated force can also provide a damping sensation for the user and assist the user in driving the rotation of the first rotating assembly 1 and the second rotating assembly 2. By achieving synchronous rotation, providing a damping sensation for the user, and assisting the user in driving the rotation of the first rotating assembly 1 and the second rotating assembly 2 through the elastic element 3, the structure of this application is simplified.

[0052] In related technologies, the structures for achieving synchronous rotation, providing damping sensation, and providing driving force to assist the rotation of the first rotating component 1 and the second rotating component 2 are generally three different structures, thus making the overall hinge mechanism quite complex.

[0053] In this embodiment, the structures of the first rotating component 1 and the second rotating component 2 can be the same or different, as long as the elastic element 3 undergoes elastic deformation when they rotate.

[0054] In this embodiment, the elastic element 3 is connected to the first rotating assembly 1 and the second rotating assembly 2. This means that when the first rotating assembly 1 rotates, it exerts a force on the elastic element 3, causing the elastic element 3 to undergo elastic deformation. The elastic force generated by this elastic deformation can act on the second rotating assembly 2, causing the second rotating assembly 2 to rotate synchronously. At the same time, when the second rotating assembly 2 rotates, it exerts a force on the elastic element 3, causing the elastic element 3 to undergo elastic deformation. The elastic force generated by this elastic deformation can act on the first rotating assembly 1, causing the first rotating assembly 1 to rotate synchronously.

[0055] In this embodiment, the elastic element 3 can provide a damping sensation when the user applies rotation. This can refer to the state of the elastic element 3 in the hinge mechanism, such as when the first rotating assembly 1 and the second rotating assembly 2 are in the unfolded position, the elastic element 3 is in a stretched or unforced state. Thus, when the first rotating assembly 1 and the second rotating assembly 2 rotate from the unfolded position to the folded position, the elastic element 3 is continuously compressed, thereby undergoing elastic deformation. The elastic force generated by the elastic deformation resists the user's rotation and provides a damping sensation. When the first rotating assembly 1 and the second rotating assembly 2 rotate from the folded position to the unfolded position, the elastic element 3 causes the first rotating assembly 1 and the second rotating assembly 2 to rotate and unfold through the force generated by the elastic deformation.

[0056] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the elastic member 3 includes a first elastic part 31 and a second elastic part 32, wherein the first elastic part 31 is connected to the first rotating assembly 1 in a transmission manner, and the second elastic part 32 is connected to the second rotating assembly 2 in a transmission manner.

[0057] With the above arrangement, the first elastic part 31 can undergo elastic deformation when the first rotating assembly 1 rotates, and this elastic deformation can drive the second rotating assembly 2 to rotate. Similarly, the second elastic part 32 can undergo elastic deformation when the second rotating assembly 2 rotates, and this elastic deformation can drive the second rotating assembly 2 to rotate. Through the first elastic part 31 and the second elastic part 32, the elastic member 3 can receive the forces from the first rotating assembly 1 and the second rotating assembly 2 and undergo elastic deformation, thereby causing the two to rotate synchronously.

[0058] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the first elastic part 31 includes a first deformation groove 3101, and the first rotating assembly 1 includes a first gear 11. The first gear 11 is rotatable and is used to extend into the first deformation groove 3101 and abut against the wall of the first deformation groove 3101 to cause the elastic member 3 to undergo elastic deformation.

[0059] With the above arrangement, the first gear 11 can rotate with the first rotating component 1. When the first gear 11 rotates, it abuts against the wall of the first deformation groove 3101, which causes the first deformation groove 3101 to deform. This deformation can cause the elastic member 3 to undergo elastic deformation as a whole, which is beneficial for the second elastic part 32 to drive the second rotating component 2 to rotate synchronously.

[0060] In some embodiments of this application, such as Figure 3 and Figure 4As shown, the second elastic part 32 includes a second deformation groove 3201, and the second rotating assembly 2 includes a second gear 21. The second gear 21 is rotatable and is used to extend into the second deformation groove 3201 and abut against the wall of the second deformation groove 3201 to cause the elastic member 3 to undergo elastic deformation.

[0061] With the above arrangement, the second gear 21 can rotate with the second rotating component 2. When the second gear 21 rotates, it abuts against the wall of the second deformation groove 3201, which causes the second deformation groove 3201 to deform. This deformation can cause the elastic member 3 to undergo elastic deformation as a whole, which is beneficial for the first elastic part 31 to drive the first rotating component 1 to rotate synchronously.

[0062] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the first elastic part 31 includes a first deformation groove 3101, and the first rotating assembly 1 includes a first gear 11. The first gear 11 is rotatable and is used to extend into the first deformation groove 3101 and abut against the wall of the first deformation groove 3101 to cause the elastic member 3 to undergo elastic deformation. The second elastic part 32 includes a second deformation groove 3201, and the second rotating assembly 2 includes a second gear 21. The second gear 21 is rotatable and is used to extend into the second deformation groove 3201 and abut against the wall of the second deformation groove 3201 to cause the elastic member 3 to undergo elastic deformation.

[0063] With the above arrangement, the elastic force generated by the compression of the first deformation groove 3101 by the first gear tooth 11 and the elastic force generated by the compression of the second deformation groove 3201 by the second gear tooth 21 can interact with each other. For example, the elastic force generated by the first deformation groove 3101 can cause the wall of the second deformation groove 3201 to abut against the second gear tooth 21, thereby driving the second gear tooth 21 to rotate, realizing the synchronous rotation of the first rotating component 1 and the second rotating component 2, and vice versa. This will not be elaborated here.

[0064] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the first elastic part 31 includes a first mating plate 311 and a second mating plate 312. One side of the first mating plate 311 is connected to one side of the second mating plate 312. The other side of the first mating plate 311 and the other side of the second mating plate 312 form an opening of a first deformation groove 3101. The opening of the first deformation groove 3101 faces the side where the first gear tooth 11 of the first rotating assembly 1 is located.

[0065] With the above arrangement, the first mating plate 311 and the second mating plate 312 can be squeezed by the first gear tooth 11, or squeezed by the first gear tooth 11, thereby driving the second gear tooth 21 to rotate under the action of the first gear tooth 11, or driving the first gear tooth 11 to rotate when the elastic member 3 is elastically deformed by the second elastic part 32. This is conducive to achieving synchronous rotation of the first rotating assembly 1 and the second rotating assembly 2.

[0066] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the second elastic part 32 includes a third mating plate 321 and a fourth mating plate 322. One side of the third mating plate 321 is connected to one side of the fourth mating plate 322. The other side of the third mating plate 321 and the other side of the fourth mating plate 322 form an opening of the second deformation groove 3201. The opening of the second deformation groove 3201 faces the side where the second gear tooth 21 of the second rotating assembly 2 is located.

[0067] With the above arrangement, the third mating plate 321 and the fourth mating plate 322 can be squeezed by the second gear tooth 21, or squeezed by the second gear tooth 21, thereby driving the first gear tooth 11 to rotate under the action of the second gear tooth 21, or driving the first gear tooth to rotate when the elastic member 3 undergoes elastic deformation caused by the first elastic part 31. This is beneficial to achieve synchronous rotation of the first rotating assembly 1 and the second rotating assembly 2.

[0068] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the first elastic part 31 includes a first mating plate 311 and a second mating plate 312. One side of the first mating plate 311 is connected to one side of the second mating plate 312, and the other side of the first mating plate 311 and the other side of the second mating plate 312 form an opening of a first deformation groove 3101. The opening of the first deformation groove 3101 faces the side where the first gear tooth 11 of the first rotating assembly 1 is located. The second elastic part 32 includes a third mating plate 321 and a fourth mating plate 322. One side of the third mating plate 321 is connected to one side of the fourth mating plate 322, and the other side of the third mating plate 321 and the other side of the fourth mating plate 322 form an opening of a second deformation groove 3201. The opening of the second deformation groove 3201 faces the side where the second gear tooth 21 of the second rotating assembly 2 is located.

[0069] With the above arrangement, the cooperation between the first mating plate 311 and the second mating plate 312 can cause the elastic member 3 to undergo elastic deformation, thereby causing the third mating plate 321 and the fourth mating plate 322 to press against the second gear tooth 21, thus achieving synchronous rotation of the first rotating assembly 1 and the second rotating assembly 2.

[0070] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the elastic member 3 includes a force transmission part 33, which is located between the first elastic part 31 and the second elastic part 32. One end of the force transmission part 33 is connected to the side of the first elastic part 31 facing the second elastic part 32, and the other end of the force transmission part 33 is connected to the side of the second elastic part 32 facing the first elastic part 31.

[0071] Through the above arrangement, the force transmission part 33 can transmit the elastic force generated by the first elastic part 31 and the second elastic part 32. This transmission effect is conducive to the same degree of elastic deformation between the first elastic part 31 and the second elastic part 32, so that the first rotating component 1 and the second rotating component 2 rotate to the same degree, achieving a synchronous effect.

[0072] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, there are multiple first elastic parts 31, multiple second elastic parts 32 and multiple force transmission parts 33. The multiple first elastic parts 31, multiple second elastic parts 32 and multiple force transmission parts 33 are arranged along the first direction X. The first elastic part 31 includes a first deformation groove 3101, the second elastic part 32 includes a second deformation groove 3201, and there is a compression cavity 301 between two adjacent force transmission parts 33. The compression cavity 301 is located between the opposite first deformation groove 3101 and second deformation groove 3201.

[0073] With the above arrangement, after each first elastic part 31 and each second elastic part 32 undergoes elastic deformation, on the one hand, they can transmit force to each other through the force transmission part 33; on the other hand, after elastic deformation, the adjacent structure can continue to abut against the first rotating assembly 1 or the second rotating assembly 2, thereby continuing to undergo elastic deformation. Furthermore, after a single first deformation groove 3101 and second deformation groove 3201 undergoes elastic deformation, its internal space is generally insufficient to accommodate the first rotating assembly 1 and the second rotating assembly 2. Multiple first elastic parts 31 and second elastic parts 32 facilitate continuous contact between the first rotating assembly 1 and the second rotating assembly 2, thereby causing the elastic element 3 to continuously undergo elastic deformation. In addition, the extrusion cavity 301 also facilitates the extrusion of the first deformation groove 3101 and the second deformation groove 3201.

[0074] In this embodiment, when the first deformation groove 3101 and the second deformation groove 3201 are compressed along the first direction X, the extrusion chamber 301 can be compressed to a similar degree simultaneously. This facilitates the simultaneous compression of both, thereby causing the elastic member 3 to undergo elastic deformation.

[0075] In some embodiments of this application, such as Figure 3 and Figure 4As shown, the extrusion chamber 301 extends through the two opposite ends of the elastic member 3 along the extension direction of the rotation axis of the first rotating assembly 1.

[0076] With the above arrangement, the extrusion cavity 301 can reduce the interference between its walls caused by deformation during deformation. At the same time, the extrusion cavity 301 of this shape also tends to be compressed and stretched along the first direction X, which is beneficial for the elastic member 3 to generate a force that makes the two rotate synchronously under the action of the first elastic part 31 and the second elastic part 32.

[0077] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the force transmission part 33 includes a guide part 331, which is located at the edge of the opening of the extrusion chamber 301.

[0078] With the above arrangement, each extrusion chamber 301 can undergo elastic deformation in sequence under the guidance of the guide part 331, and the first deformation groove 3101 and the second deformation groove 3201 can undergo elastic deformation synchronously. This is beneficial for the first elastic part 31 and the second elastic part 32 to rotate the first rotating assembly 1 and the second rotating assembly 2 synchronously.

[0079] A second aspect of this application provides an electronic device that includes a hinge mechanism as described above.

[0080] Because of the hinge mechanism of the above embodiments, the electronic device of this application has the same technical effects as the above embodiments, which will not be repeated here.

[0081] In this application embodiment, the electronic device can be a smartphone, tablet computer, smartwatch, or other similar product.

[0082] In some embodiments of this application, such as Figure 1 , Figure 2 and Figure 5 As shown, the electronic device includes a first middle frame 4 and a second middle frame 5. The first rotating component 1 is driven to the first middle frame 4, and the second rotating component 2 is driven to the second middle frame 5.

[0083] By rotating the first middle frame 4 and the second middle frame 5, the electronic device can be in an unfolded or folded state, which makes it easier for users to store the electronic device.

[0084] In some embodiments of this application, such as Figure 5As shown, the electronic device includes a first magnetic 6 and a second magnetic 7. The first magnetic 6 is located in the first middle frame 4, and the second magnetic 7 is located in the second middle frame 5. The first rotating assembly 1 and the second rotating assembly 2 can be rotated to make the first magnetic 6 and the second magnetic 7 be arranged opposite each other. When the first rotating assembly 1 and the second rotating assembly 2 are rotated to the folded position, the elastic member 3 is compressed.

[0085] With the above arrangement, when the first rotating component 1 and the second rotating component 2 rotate to the folded position, the elastic element 3 is compressed, which makes it easy for both to rotate to the unfolded position. By arranging the first magnetic element 6 and the second magnetic element 7, both can maintain the folded state through magnetic attraction when they are in the folded position.

[0086] In addition, the elastic element 3, which is in a compressed state, can be restored and drive the first rotating component 1 and the second rotating component 2 to rotate to the unfolded position; during the process of the first rotating component 1 and the second rotating component 2 rotating to the folded position, it is subjected to the elastic force generated by compression, thus providing the user with a damping sensation.

[0087] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
