Description
TECHNICAL FIELD

[0002] With the development of science and technology, and with the extreme pursuit of users for use experience, the functions of electronic devices such as mobile phones and tablet computers are becoming more and more rich. Foldable electronic devices have received widespread attention from users because they can balance a large display area and a small storage volume. In actual application, a hinge mechanism is usually provided in the foldable electronic device to realize switching between an unfolded state and a folded state through rotation of the hinge mechanism.
[0003] In the related art, the hinge structure can specifically include a synchronous swing arm, a door plate and the like, the synchronous swing arm is usually provided with a door plate shaft and a protruding support portion, and the door plate is provided with a sliding groove for guiding movement of the door plate shaft. When the electronic device falls in the folded state, in order to control the support portion on the synchronous swing arm to abut against the door plate, so as to avoid sliding of the synchronous swing arm along the thickness direction of the electronic device, the end of the sliding groove of the door plate needs to be enlarged to avoid the door plate shaft from coming out. However, in the case where the electronic device needs to be opened at a small angle, the design of enlarging the end of the sliding groove may cause scratching noise when the door plate crosses the support portion, resulting in the phenomenon that the electronic device is not smooth when opened at a small angle, which greatly affects the use experience of the user for the foldable electronic device. That is, the existing foldable electronic device is difficult to balance the reliable support of the synchronous swing arm when falling in the folded state and the smoothness when opened at a small angle.

Refer to Figure 13 A structural schematic diagram of the synchronous swing arm in the hinge mechanism is shown. Refer to Figure 14 A structural schematic diagram of the synchronous swing arm in the hinge mechanism is shown.
[0046] As shown in Figures 1 to 8 , the hinge mechanism can specifically include: a hinge body 10, and a synchronous swing arm 11, a door plate 12, and an elastic member 13 connected to the hinge body 10; wherein the synchronous swing arm 11 is provided with a first sliding shaft 111 and a support portion 112 protruding towards the door plate 12; the door plate 12 is provided with a sliding groove 121, and the first sliding shaft 111 is inserted into the sliding groove 121 and can move along the sliding groove 121; the elastic member 13 can include a guide section 131, and the elastic member 13 is arranged between the door plate 12 and the synchronous swing arm 11, and the guide section 131 abuts against one of the door plate 12 or the support portion 112.
[0047] In the embodiment of the present application, the elastic member 13 is arranged between the door plate 12 and the support portion 112 of the synchronous swing arm 11, the elastic member 13 has a guide section 131, and the guide section 131 abuts against one of the door plate 12 or the support portion 112 of the synchronous swing arm 11. In the case that the electronic device is in a folded state and is hit, the elastic member 13 can absorb the impact force applied by the synchronous swing arm 11 to the door plate 12 by deforming, so as to reliably support the synchronous swing arm 11 and limit the sliding of the synchronous swing arm 11 along the thickness direction of the electronic device. In the case that the electronic device needs to be opened at a small angle, due to the supporting effect of the guide section 131 on the synchronous swing arm 11, there can be sufficient clearance between the support portion 112 of the synchronous swing arm 11 and the door plate 12, so that the door plate 12 can smoothly cross the support portion 112. That is, the hinge mechanism provided by the embodiment of the present application can not only achieve reliable support of the synchronous swing arm 11 when the electronic device falls in a folded state, but also take into account the smoothness of the electronic device when it is opened at a small angle.
[0048] In specific applications, the hinge body 10 serves as the main structural component of the hinge mechanism, and may specifically include a hinge bracket 101, a virtual swing arm 102, and a mid-frame bracket 14. Both the synchronous swing arm 11 and the door panel 12 can be connected to the hinge body 10. Specifically, the synchronous swing arm 11 can be slidably connected to the mid-frame bracket 14, while the door panel 12 can be rotatably connected to the mid-frame bracket 14. The synchronous swing arm 11 can be rotatably connected to the hinge bracket 101 via a pivot.
[0049] like Figure 4 As shown, a first sliding shaft 111 is provided on the synchronous swing arm 11, and a sliding groove 121 is provided on the door panel 12. The first sliding shaft 111 is inserted into the sliding groove 121 and can slide along the sliding groove 121 to realize the relative movement between the door panel 12 and the synchronous swing arm 11. Typically, the first sliding groove 121 is located at the end of the sliding groove 121 ( Figure 4 When the electronic device is in the top position (at the top of the panel), it is usually in a folded state. During the unfolding of the electronic device, the first sliding shaft 111 can move along the slide groove 121 to press the door panel 12 towards the center, thereby unfolding the electronic device.
[0050] like Figure 3 As shown, the synchronous swing arm 11 is also provided with a support portion 112 protruding towards the door panel 12. The hinge mechanism in the electronic device is in... Figure 1 In the folded state shown and under impact, the synchronous swing arm 11 may be subjected to impact along the thickness direction of the electronic device. Figure 3 (In the direction indicated by the middle arrow) the door panel 12 moves. Since the door panel 12 and the support portion 112 are positioned opposite each other, during the movement of the synchronous swing arm 11 along the thickness direction of the electronic device, the door panel 12 may abut against the support portion 112, restricting further movement of the synchronous swing arm 11. That is, the cooperation between the door panel 12 and the support portion 112 can be used to limit the amount of slippage of the synchronous swing arm 11. Furthermore, in order to reliably limit the door panel 12 against the support portion 112, it is necessary to prevent the first sliding shaft 111 from disengaging from the end of the slide groove 121 and pressing the door panel 12 towards the center when the synchronous swing arm 11 is subjected to impact.
[0051] like Figure 1 As shown, since an elastic element 13 is provided between the support portion 112 of the synchronous swing arm 11 and the door panel 12, when the electronic device is in a folded state and is impacted, the elastic element 13 can absorb the impact force exerted by the synchronous swing arm 11 on the door panel 12 by deformation, thereby achieving reliable support for the synchronous swing arm 11. This prevents the first sliding shaft 111 on the synchronous swing arm 11 from dislodging from the end of the slide groove 121 and squeezing the door panel 12 towards the center under impact. The door panel 12 and the support portion 112 can always remain in place. Figure 2The positional relationship shown means that the door panel 12 can always be positioned relative to the support part 112 in the thickness direction of the electronic device, so as to limit the sliding amount of the synchronous swing arm 11 in the thickness direction of the electronic device by means of the door panel 12.
[0052] Moreover, the electronic device is in Figure 5 As shown in the case of opening at a small angle. Figure 6 As shown, due to the supporting effect of the guide section 131 on the elastic member 13 on the synchronous swing arm 11, there can be a sufficient gap between the support part 112 of the synchronous swing arm 11 and the door panel 12 (e.g., Figure 7 As shown in the figure, this allows the door panel 12 to smoothly pass over the support portion 112. That is, the hinge mechanism provided in this embodiment can not only reliably support the synchronous swing arm 11 when the electronic device is in a folded state and falls, but also ensure the smoothness of the electronic device when it is opened at a small angle.
[0053] like Figure 2 and Figure 6 As shown, the elastic element 13 can be connected to the door panel 12. For example... Figures 12 to 14 As shown, a second sliding shaft 113 is provided on the synchronous swing arm 11, and the second sliding shaft 113 abuts against the guide section 131. Figure 2 As shown, when the electronic device is in a folded state and is impacted, the impact on the synchronous swing arm 11 can be applied to the guide section 131 of the elastic member 13 through the second sliding shaft 113. After being impacted, the guide section 131 of the elastic member 13 can collapse and deform, converting the impact kinetic energy into elastic potential energy, preventing the first sliding shaft 111 on the synchronous swing arm 11 from pressing the door panel 12 towards the center. This ensures reliable support of the door panel 12 for the synchronous swing arm 11, limiting the amount of slippage of the synchronous swing arm 11. In practical applications, after the impact on the electronic device is removed, the guide section 131 of the elastic member 13 can quickly return to its initial contour shape.
[0054] In practical applications, by connecting the elastic element 13 to the door panel 12, the elastic element 13 can be reliably fixed between the door panel 12 and the synchronous swing arm 11, thus achieving reliable support for the synchronous swing arm 11 by the elastic element 13. At the same time, since the structure of the door panel 12 is relatively simple, the layout and connection operation of connecting the elastic element 13 to the door panel 12 are also relatively simple.
[0055] It should be noted that, in specific applications, those skilled in the art can also connect the elastic element 13 to the synchronous swing arm 11 according to actual needs, or connect it independently between the door panel 12 and the synchronous swing arm 11. The embodiments of this application do not specifically limit the position of the elastic element 13.
[0056] In actual application, in order to realize reliable support for the synchronous swing arm 11, the trajectory of the guide segment 131 on the elastic member 13 is usually different from the trajectory of the sliding groove 121 on the door plate 12. In the embodiment of the present application, in order to enable the second sliding shaft 113 to always closely fit and move along the guide segment 131, and to enable the first sliding shaft 111 to always closely fit and move along the sliding groove 121, as shown in Figures 12 to 14 the first sliding shaft 111 and the second sliding shaft 113 can be arranged in a non-aligned manner along the axial direction of the hinge mechanism.
[0057] In actual application, the first sliding shaft 111 and the second sliding shaft 113 can be arranged in a staggered manner in the thickness direction of the electronic device, or can be arranged in a staggered manner in the width direction of the electronic device, and the embodiment of the present application does not make specific limitation on the positional relationship between the first sliding shaft 111 and the second sliding shaft 113. Moreover, in specific operation, the first sliding shaft 111 and the second sliding shaft 113 can be arranged on the same component in the synchronous swing arm 11, or can be arranged on different components in the synchronous swing arm 11, and the embodiment of the present application does not make specific limitation on the specific arrangement position of the first sliding shaft 111 and the second sliding shaft 113 in the synchronous swing arm 11.
[0058] As shown in Figures 9 to 11 the guide segment 131 is arranged in an arc shape at least in part, and the elastic member 13 can further include a connecting segment 132 connected to the guide segment 131; wherein the connecting segment 132 is connected to the door plate 12 or the synchronous swing arm 11. In actual application, by arranging a special connecting segment 132 to connect the elastic member 13 to the door plate 12 or the synchronous swing arm 11, the operation of directly connecting the guide segment 131 to the door plate 12 or the synchronous swing arm 11 can be avoided, so that the deformation amount of the guide segment 131 can be further increased, to realize reliable support of the guide segment 131 for the synchronous swing arm 11.
[0059] Optionally, the shape of the connecting segment 132 is adapted to the door plate 12 or the synchronous swing arm 11 connected thereto, to enhance the connection reliability between the connecting segment 132 and the door plate 12 or the synchronous swing arm 11 connected thereto. For example, in the case where the connecting segment 132 is connected to the door plate 12, in the case where the door plate 12 is a planar structure, the connecting segment 132 can correspondingly be a flat segment, to enhance the connection reliability therebetween.
[0060] As shown in Figures 9 to 11As shown, the elastic member 13 further comprises a reinforcing segment 133, and the guide segment 131 is arranged between the connecting segment 132 and the reinforcing segment 133. In a specific application, the reinforcing segment 133 can be used to strengthen the guide segment 131, and facilitate the guide segment 131 to quickly return to the initial state after deformation, thereby further improving the support reliability of the elastic member 13 to the synchronous swing arm 11.
[0061] Optionally, the reinforcing segment 133 is folded towards the guide segment 131, so that on the one hand, the arrangement of the reinforcing segment 133 is easy to implement, and on the other hand, by folding the reinforcing segment 133 into the space enclosed by the connecting segment 132 and the guide segment 131, the reinforcing segment 133 can also avoid occupying the space outside the elastic member 13. Thus, the space occupied by the elastic member 13 can be reduced, which is conducive to the overall layout of the elastic member 13 in the hinge mechanism.
[0062] In some optional embodiments of the present application, as shown in Figures 9 to 12 As shown, the door plate 12 can comprise a flat portion, the connecting segment 132 is a flat segment, and the connecting segment 132 is connected to the flat portion of the door plate 12 to achieve reliable connection between the connecting segment 132 and the door plate 12; the guide segment 131 is an arc-shaped protrusion, one end of the guide segment 131 is connected to the connecting segment 132, and the other end of the guide segment 131 is connected to the reinforcing segment 133; the reinforcing segment 133 is folded towards the guide segment 131 away from the end connected to the guide segment 131, so as to enhance the strength of the guide segment 131. The reinforcing segment 133 has the same extension direction as the connecting segment 132, so that the overall volume of the elastic member 13 is smaller, and the layout of the elastic member 12 between the synchronous swing arm 11 and the door plate 12 is facilitated.
[0063] Optionally, the connecting segment 132 is welded to the door plate 12 or the synchronous swing arm 11 to achieve the connection reliability between the elastic member 13 and the door plate 12 or the synchronous swing arm 11. Moreover, since welding is a relatively simple process, the operability of welding the connecting segment 132 to the door plate 12 or the synchronous swing arm 11 is stronger.
[0064] It should be noted that in actual applications, those skilled in the art can also connect the connecting segment 132 to the door plate 12 or the synchronous swing arm 11 by means of bonding or clamping, and the embodiments of the present application do not make specific limitations on the connection mode of the connecting segment 132 on the door plate 12 or the synchronous swing arm 11.
[0065] In some optional embodiments of the present application, the elastic member 13 can be a metal spring piece, so that the elastic member 13 can have a larger elastic force to achieve reliable support for the synchronous swing arm 11.
[0066] It should be noted that in actual applications, a component capable of elastic deformation such as a spring can also be selected as the elastic member 13 in the embodiments of the present application, and the embodiments of the present application do not make a specific limitation in this regard.
[0067] Optionally, as shown in Figure 9 and Figure 11 The shape of the guide segment 131 can be a convex arc shape, and the second sliding shaft 113 of the synchronous swing arm 11 can be reliably supported by pressing or moving along the arc-shaped guide segment 131. Since the arc-shaped guide segment 131 has a simple shape, it is easy to implement.
[0068] Optionally, the shape of the guide segment 131 can also be a coiled shape, and the outermost end of the coiled guide segment 131 can be connected to the synchronous swing arm 11 or the door panel 12 by welding or bonding. The second sliding shaft 113 of the synchronous swing arm 11 can be reliably supported by pressing or moving along the coiled guide segment 131. Since the coiled guide segment 131 has a complex shape and can absorb more buffer force, when the shape of the guide segment 131 is coiled, it is beneficial to design a more complex trajectory, and it can have greater impact absorption capacity, which is beneficial to further improve the support reliability of the synchronous swing arm 11.
[0069] It should be noted that in specific applications, the shape of the guide segment 131 can be set to an arc shape or a coiled shape according to actual needs, and the embodiments of the present application do not make a specific limitation on the shape of the guide segment 131.
[0070] In summary, the hinge mechanism described in the embodiments of the present application can at least have the following advantages:
[0071] In the embodiment of the present application, the elastic member is arranged between the door plate and the support part of the synchronous swing arm, the elastic member has a guide segment, and the guide segment abuts against one of the door plate or the support part of the synchronous swing arm. In the case that the electronic device is in the folded state and is impacted, the elastic member can absorb the impact force applied by the synchronous swing arm to the door plate by deforming, so as to reliably support the synchronous swing arm and limit the sliding of the synchronous swing arm along the thickness direction of the electronic device. In the case that the electronic device needs to be opened at a small angle, due to the support effect of the guide segment on the synchronous swing arm, the support part of the synchronous swing arm and the door plate can have sufficient clearance, so that the door plate can smoothly cross the support part. That is, the hinge mechanism provided in the embodiment of the present application can not only achieve reliable support of the synchronous swing arm when the electronic device falls in the folded state, but also take into account the smoothness of the electronic device when it is opened at a small angle.
