Fig. 1 is a schematic structural diagram of a hinge component 100 according to an exemplary embodiment. FIG. 2 is an exploded schematic view of the hinge component 100 in FIG. 1 . The hinge component 100 may include an unfolded state and a folded state. When the hinge component 100 is switched between the unfolded state and the folded state, the electronic device configured with the hinge component 100 may be driven to perform a corresponding state change. For example, when the hinge component 100 is in an unfolded state, the electronic device configured with the hinge component 100 is in a flat state, and when the hinge component 100 is in a folded state, the electronic device configured with the hinge component 100 is in a folded state. In this folded state, the flexible screen of the electronic device is correspondingly folded in half. It is understandable that when the flexible screen is bent, the bent area of the flexible screen needs to occupy a certain space for deformation, and the space The size is closely related to the internal stress of the flexible screen after deformation. Therefore, the coordination between the state switching of the hinge component 100 and the bending track and posture of the flexible screen has become an important research object of foldable electronic devices.

Based on this, the present disclosure provides a hinge component 100 as shown in FIGS. 1 and 2 . The hinge component 100 may include a rotating assembly 1 , a first support 2 and a second support 3 . The first support 2 includes a first support surface, and the second support 3 includes a second support surface. Both the first support surface and the second support surface can be used to support the flexible screen of the electronic device to improve the flexibility of the flexible screen. rigidity. The rotating assembly 1 can be used to switch the state of the hinge part 100, for example, the rotation of the rotating assembly 1 can drive the hinge part 100 to switch to a folded state or an unfolded state; overlapping, and the first support member 2 and the rotating assembly 1 can be slidably connected along the first direction; the second support member 3 can be flexibly connected with the rotating assembly 1, so that when the rotating assembly 1 rotates, the second supporting member 3 can correspondingly Part of the structural movement of the rotating assembly 1 causes the hinge component 100 to switch to an unfolded state or a folded state. Wherein, the first direction is the direction shown by arrow A in FIG. The flexible connection may include a sliding connection or a rotating connection, and the specific design is based on the fact that the second support member 3 will not be stuck when the rotating assembly 1 rotates.

3-5 schematically show the relative positional relationship between the flexible screen and the first support 2 and the second support 3 when the hinge component 100 is in different states. Specifically, when the hinge component 100 is in the unfolded state as shown in FIG. 3 , the flexible screen is in a flat state, and the first support surface of the first support member 2 and the second support surface of the second support member 3 are located on the same plane. , and the first support surface and the second support surface can be arranged side by side along the second direction. At this time, the first support surface of the first support member 2 and the second support surface of the second support member 3 cooperate to support the flexible screen, avoiding the The first support surface and the second support surface are arranged in a step shape, which causes deformation of the flexible screen, and at the same time can help to improve the rigidity of the flexible screen and reduce the deformation of the flexible screen. Wherein, the second direction is perpendicular to the first direction, as shown in FIG. 3 , the second direction is the direction indicated by arrow B.

FIG. 4 shows a diagram of an intermediate state when the hinge component 100 switches from the unfolded state to the folded state. As shown in FIG. 4 , when the hinge part 100 switches from the unfolded state to the folded state, the rotating assembly 1 can rotate along the axis, and the rotation of the rotating assembly 1 can drive the first support member 2 to slide toward the rotating assembly 1 along the first direction. Sliding, the second supporting member 3 rotates with the part connected to the rotating assembly 1 until the hinge part 100 is switched to the folded state shown in FIG. 5 . When the hinge part 100 is in the folded state, the first support surface of the first support member 2 and the second support surface of the second support member 3 form a first preset angle, such as the first support surface and the second support surface shown in FIG. The support surfaces may form an angle α.

Since the first support member 2 slides toward the rotating assembly 1 along the first direction when the hinge part 100 is switched to the folded state, it is assumed that in the unfolded state, the axes of the first support member 2 and the rotating assembly 1 are in the first direction. There is a first distance upward, and in the folded state, the first support member 2 and the axis of the rotating assembly 1 are separated by a second distance in the first direction, then the first distance will be greater than the second distance. Therefore, when the flexible screen bends along with the folding of the hinge part 100, due to the movement of the first support member 2 toward the rotating assembly 1, an avoidance space can be provided for the bending of the flexible screen, so that the flexible screen can be bent in a larger space. Bending reduces the excessive deformation of the flexible screen caused by the cooperation of the first support member 2 and the second support member 3, which is beneficial to reduce the internal stress of the flexible screen; and when the hinge part 100 switches from the folded state to the unfolded state, the first support member The first support surface of 2 and the second support surface of the second support member 3 move towards the same plane, which is beneficial to support the various positions of the flexible screen after it is flattened, and is beneficial to avoid bending of the flexible screen. Wherein, as shown in FIG. 5 , the first preset angle can be an acute angle, so that the end of the second support 3 close to the first support 2 can cooperate with the first support 2 to form a larger avoidance space, It is beneficial to reduce the internal stress of the flexible screen. Of course, only the first preset angle is described as an acute angle. In other embodiments, the first preset angle may also include a right angle or an obtuse angle, which is not limited in the present disclosure.

In the embodiment shown in FIGS. 1-5 , the hinge component 100 includes two second supports 3 , and when the hinge component 100 is in an unfolded state, one of the second supports 3 is located on one side of the first support 2 . On one side, the other supporting member is located on the other side opposite to the first supporting member 2 , so that the flexible screens located on both sides of the first supporting member 2 can be supported by the two second supporting members 3 . Of course, in the embodiment provided by the present disclosure, the hinge part 100 includes two second supports 3 as an example for illustration. In other embodiments, the hinge part 100 may also include three or more than three The second support 3, wherein when the hinge part 100 is in the unfolded state, at least one second support 3 is located on one side of the first support 2, and at least one second support 3 is located on the other side opposite to the first support 2. On the other hand, the specific number of the second support members 3 can be designed as required, which is not limited in the present disclosure.

Similarly, in the embodiments provided in the present disclosure, the hinge component 100 includes a single first support member 2 as an example for illustration. In other embodiments, the hinge component 100 may also include two or more first supports 2, and the two or more first supports 2 may be arranged side by side along the axial direction of the rotating assembly 1, Each first support member 2 can be connected with one or more rotating assemblies 1 . For example, in the embodiment provided by the present disclosure, the hinge component 100 may include two rotating assemblies 1, the first end of the first support member 2 arranged along the axial direction of the rotating assemblies 1 is connected to one of the rotating assemblies 1, and the first The second end of the support member 2 disposed along the axial direction of the rotating assembly 1 is connected to another rotating assembly 1 . Alternatively, in other embodiments, the hinge component 100 may also be a single rotating assembly 1 , or the hinge component 100 may include three or more rotating assemblies 1 , which is not limited in the present disclosure.

The structure included in the hinge component 100 will be described in detail below based on the hinge component 100 provided in the present disclosure as an example. It should be noted that, in the following embodiments, when the hinge component 100 includes multiple identical structures, one of them will be used for illustration, and the others can be referred to accordingly, which will not be repeated in this disclosure.

The axis of the second shaft part 122 and the axis of the third shaft part 123 are not in the same plane. For example, as shown in FIG. The axis of 122 and the axis of the third rotating shaft portion 123 are beneficial to meet the position requirements of the first support member 2 . Of course, in some other embodiments, the second preset included angle can also be equal to 180°, at this time, the axis of the first shaft part 121, the axis of the second shaft part 122 and the axis of the third shaft part 123 are on the same plane . Wherein, the first connecting portion 124 and the second connecting portion 125 may be arranged in a rod-shaped structure.
