[0057] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0058] Figure 1Schematic diagram of the structure of a rotating shaft mechanism of an electronic device provided in an embodiment of the present application. Figure 1 It can be seen that the rotating shaft mechanism 10 may include: a first rotating component 101 and a second rotating component 102 .

[0059] The first rotating assembly 101 may be located in the first body of the electronic device, and the first rotating assembly 101 may be used to be fixedly connected to the first body. The second rotating assembly 102 may be located in the second body of the electronic device, and the second rotating assembly 102 may be used to be fixedly connected to the second body. Furthermore, the first rotating assembly 101 may be rotatably connected to the second rotating assembly 102, thereby realizing the relative rotation of the first body and the second body of the electronic device.

[0060] Figure 2 yes Figure 1 An exploded schematic diagram of the shaft mechanism is shown. Figure 3 is a schematic diagram of the structure of a first rotating assembly provided in an embodiment of the present application. Figure 2 and Figure 3 , the first rotating component 101 may have a first through hole 101a. Figure 4 is a schematic diagram of the structure of a second rotating assembly provided in an embodiment of the present application. Figure 2 and Figure 4 , the second rotating component 102 may have a second through hole 102a.

[0061] Combination Figures 1 to 4 , the first through hole 101a is connected to the second through hole 102a, and the axis A1 of the first through hole 101a and the axis A2 of the second through hole 102a may both intersect with the target rotation axis X. The target rotation axis X is the rotation axis between the first rotating component 101 and the second rotating component 102. For example, the axis A1 of the first through hole 101a and the axis A2 of the second through hole 102a may both be perpendicular to the target rotation axis X.

[0062] refer to Figure 5 The first through hole 101a and the second through hole 102a can be used to set the flexible circuit board 20 of the electronic device. That is, the flexible circuit board 20 of the electronic device can be set in the first through hole 101a and the second through hole 102a, thereby preventing the flexible circuit board 20 from being damaged, and the reliability of the electronic device is higher. In addition, the flexible circuit board 20 is set inside the hinge mechanism 10, which has a better aesthetic appearance.

[0063] In summary, the embodiment of the present application provides a hinge mechanism of an electronic device, wherein the first rotating assembly in the hinge mechanism has a first through hole, and the second rotating assembly has a second through hole. The flexible circuit board of the electronic device can be arranged in the first through hole and the second through hole, so that the first rotating assembly and the second rotating assembly can protect the flexible circuit board and avoid damage to the flexible circuit board, and the reliability of the electronic device is high. In addition, the flexible circuit board is arranged inside the hinge mechanism, which has a better aesthetic appearance.

[0064] Combination Figure 3 and Figure 6 It can be seen that the first rotating assembly 101 may include: a first plate 1011 and a first protruding structure 1012. The first surface 1011a of the first plate 1011 may be fixedly connected to the first protruding structure 1012, and the second surface 1011b of the first plate 1011 may be used to be fixedly connected to the first body of the electronic device. The first through hole 101a may pass through the first protruding structure 1012 and the first plate 1011, and the axis A1 of the first through hole 101a may be perpendicular to the second surface 1011b of the first plate 1011.

[0065] Since the first through hole 101a passes through the first protruding structure 1012 and the first plate body 1011, one end of the flexible circuit board 20 of the electronic device can pass through the first through hole 101a and be located on a side of the first plate body 1011 away from the first protruding structure 1012, and the other end of the flexible circuit board 20 can be located on a side of the first protruding structure 1012 away from the first plate body 1011. That is, the two ends of the flexible circuit board 20 can be located on both sides of the first rotating component 101, respectively.

[0066] Combination Figure 4 and Figure 7 It can be seen that the second rotating assembly 102 may include: a second plate 1021 and a second protruding structure 1022. The first surface 1021a of the second plate 1021 may be fixedly connected to the second protruding structure 1022, and the first surface 1021a of the second plate 1021 may also be used to be fixedly connected to the second body of the electronic device. The second through hole 102a may be provided on the second protruding structure 1022, and the axis A2 of the second through hole 102a may be perpendicular to the second surface 1021b of the second plate 1021.

[0067] refer to Figure 7It can be seen that the second plate body 1021 may have a third through hole 1021c. The second protruding structure 1022 has a groove (not shown in the figure) connected to the third through hole 1021c and the second through hole 102a on one side close to the second plate body 1021. The first protruding structure 1012 of the first rotating component 101 may pass through the third through hole 1021c and be located in the groove. In addition, the first protruding structure 1012 is rotatably connected to the second protruding structure 1022, thereby realizing the rotatable connection between the first rotating component 101 and the second rotating component 102.

[0068] Since the groove of the second protruding structure 1022 is connected to the second through hole 102a, and the first protruding structure 1012 is located in the groove, the first through hole 101a and the second through hole 102a can be connected through the groove of the second protruding structure 1022. Thus, one end of the flexible circuit board 20 of the electronic device can pass through the second through hole 102a and the first through hole 101a in sequence, and be located on the side of the first rotating component 101 away from the second rotating component 102. The other end of the flexible circuit board 20 can be located on the side of the second rotating component 102 away from the first rotating component 101. That is, the two ends of the flexible circuit board 20 can be located on both sides of the first rotating component 101 and the second rotating component 102, respectively.

[0069] refer to Figure 3 It can be seen that the first surface 1011a of the first plate body 1011 may include: a first plane 1011a1 and a second plane 1011a2. Figure 1 and Figure 3 The angle α formed by the side of the first plane 1011a1 close to the second surface 1011b of the first plate 1011 and the side of the second plane 1011a2 close to the second surface 1011b of the first plate 1011 is an obtuse angle. This facilitates the relative rotation between the first rotating assembly 101 and the second rotating assembly 102, and ensures the reliability of the rotation of the first rotating assembly 101 and the second rotating assembly 102.

[0070] In the embodiment of the present application, after the first protrusion structure 1012 passes through the third through hole 1021c of the second plate body 1021 and is located in the groove of the second protrusion structure 1022, the first surface 1011a of the first plate body 1011 is close to the second surface 1021b of the second plate body 1021 relative to the second surface 1011b of the first plate body 1011.

[0071] Furthermore, since the angle α formed by the side of the first plane 1011a1 close to the second surface 1011b of the first plate 1011 and the side of the second plane 1011a2 close to the second surface 1011b of the first plate 1011 is an obtuse angle, the first plane 1011a1 and the second plane 1011a2 of the first plate 1011 are not coplanar. Furthermore, the second surface 1021b of the second plate 1021 can contact the intersection of the first plane 1011a1 and the second plane 1011a2, thereby ensuring the tightness between the first rotating assembly 101 and the second rotating assembly 102, preventing water vapor or dust from entering the shaft mechanism from the gap between the first plate 1011 and the second plate 1021, and the reliability of the shaft mechanism is high.

[0072] After the first rotating assembly 101 and the second rotating assembly 102 rotate relative to each other, the second surface 1021b of the second plate 1021 may contact one of the first plane 1011a1 and the second plane 1011a2.

[0073] In the embodiment of the present application, the sum of the angle β formed by the second surface 1021b of the second plate body 1021 and the first plane 1011a1, the angle γ formed by the second surface 1021b of the second plate body 1021 and the first plane 1011a1, and the angle α formed by the first plane 1011a1 and the second plane 1011a2 can be equal to 180° (degrees), that is, α+β+γ=180°.

[0074] The angle α formed by the first plane 1011a1 and the second plane 1011a2 can be a fixed value. The angle β formed by the second surface 1021b of the second plate 1021 and the first plane 1011a1, and the angle γ formed by the second surface 1021b of the second plate 1021 and the first plane 1011a1 can change with the rotation of the first rotating component 101 and the second rotating component 102.

[0075] Assuming that the angle α formed by the first plane 1011a1 and the second plane 1011a2 is 160°, the sum of the angle of the angle β formed by the second surface 1021b of the second plate 1021 and the first plane 1011a1 and the angle γ formed by the second surface 1021b of the second plate 1021 and the second plane 1011a2 may be 20°. Assuming that the angle α formed by the first plane 1011a1 and the second plane 1011a2 is 120°, the sum of the angle β formed by the second surface 1021b of the second plate 1021 and the first plane 1011a1 and the angle γ formed by the second surface 1021b of the second plate 1021 and the first plane 1011a1 may be 60°.

[0076] Assuming that the angle α formed by the first plane 1011a1 and the second plane 1011a2 is 160°, if the second surface 1021b of the second plate 1021 contacts the first plane 1011a1 (the angle β formed by the second surface 1021b of the second plate 1021 and the first plane 1011a1 is 0°), then the angle γ formed by the second surface 1021b of the second plate 1021 and the second plane 1011a2 is 20°. Alternatively, assuming that the angle α formed by the first plane 1011a1 and the second plane 1011a2 is 160°, if the second surface 1021b of the second plate 1021 contacts the second plane 1011a2 (the angle γ formed by the second surface 1021b of the second plate 1021 and the second plane 1011a2 is 0°), then the angle β formed by the second surface 1021b of the second plate 1021 and the first plane 1011a1 is 20°.

[0077] In the embodiment of the present application, the angle β formed by the second surface 1021b of the second plate body 1021 and the first plane 1011a1, and the sum of the angles of the angle γ formed by the second surface 1021b of the second plate body 1021 and the second plane 1011a2 (β+γ=180°-α) can be called the maximum rotation angle allowed by the rotating shaft mechanism 10. It can be seen from this that the maximum rotation angle allowed by the rotating shaft mechanism 10 is negatively correlated with the angle α formed by the first plane 1011a1 and the second plane 1011a2. That is, the larger the angle α formed by the first plane 1011a1 and the second plane 1011a2, the smaller the maximum rotation angle allowed by the rotating shaft mechanism 10, and the smaller the angle α formed by the first plane 1011a1 and the second plane 1011a2, the larger the maximum rotation angle allowed by the rotating shaft mechanism 10.

[0078] Optionally, the maximum rotation angle allowed by the hinge mechanism 10 may be equal to the sum of a first maximum rotation angle allowed by the second rotating component 102 relative to the first rotating component 101 in the first direction B1 and a second maximum rotation angle allowed by the second rotating component 102 relative to the first rotating component 101 in the second direction B2.

[0079] The first direction B1 may be a direction in which the second surface 1021b of the second plate 1021 is away from the first plane 1011a1 and close to the second plane 1011a2. The second direction B2 may be a direction in which the second surface 1021b of the second plate 1021 is away from the second plane 1011a2 and away from the first plane 1011a1.

[0080] In order to ensure the symmetry of the rotation of the first rotating assembly 101 and the second rotating assembly 102, the first maximum rotation angle may be equal to the second maximum rotation angle. The first maximum rotation angle may be equal to the angle β formed by the second surface 1021b of the second plate 1021 and the first plane 1011a1 of the first plate 1011 when the second surface 1021b of the second plate 1021 is parallel to the second surface 1011b of the first plate 1011. The second maximum rotation angle may be equal to the angle γ formed by the second surface 1021b of the second plate 1021 and the second plane 1011a2 of the first plate 1011 when the second surface 1021b of the second plate 1021 is parallel to the second surface 1011b of the first plate 1011.

[0081] refer to Figure 3 It can be seen that the axis Y of the first protruding structure 1012 can be parallel to the intersection line Z of the first plane 1011a1 and the second plane 1011a2. Therefore, the first protruding structure 1012 can be symmetrical with respect to the intersection line Z of the first plane 1011a1 and the second plane 1011a2, thereby ensuring the structural symmetry of the first rotating assembly 101, and further ensuring the stability of the rotation of the first rotating assembly 101 and the second rotating assembly 102.

[0082] refer to Figure 3 and Figure 6 , the first protruding structure 1012 may have a fourth through hole 1012a, and the axis of the fourth through hole 1012a may be parallel to the target rotation axis X. Figure 4 and Figure 7 , the second protruding structure 1022 may have a fifth through hole 1022a, and the axis of the fifth through hole 1022a may be parallel to the target rotation axis X. Figure 8 It can also be seen that the shaft mechanism 10 may further include: a first connecting member 103. The first connecting member 103 may pass through the fifth through hole 1022a and be connected to the fourth through hole 1012a.

[0083] In the embodiments of the present application, Fig. 9 is a partial cross-sectional view of a first rotating assembly and a second rotating assembly provided in an embodiment of the present application. Fig. 9, the fourth through hole 1012a can be a non-through hole. Thus, the first through hole 101a disposed on the first protruding structure 1012 and the fourth through hole 1012a disposed on the first protruding structure 1012 are not connected, so as to avoid the mutual influence between the first connecting member 103 disposed in the fourth through hole 1012a and the flexible circuit board 20 disposed in the first through hole 101a, thereby ensuring the reliability of the rotating shaft mechanism 10. In addition, since the first connecting member 103 needs to pass through the fifth through hole 1022a to connect with the fourth through hole 1012a, the fifth through hole 1022a needs to pass through the second protruding structure 1022.

[0084] refer to Fig. 9 , the first protruding structure 1012 may have two fourth through holes 1012a, and the second protruding structure 1022 may have two fifth through holes 1022a corresponding to the two fourth through holes 1012a. Fig.10 , the shaft mechanism 10 may include two first connecting members 103. Each first connecting member 103 may pass through a fifth through hole 1022a and be connected to a fourth through hole 1012a corresponding to the fifth through hole 1022a.

[0085] refer to Figure 4 and Figure 7 The second protrusion structure 1022 may have a groove 1022b, and the fifth through hole 1022a may be disposed in the groove 1022b. Fig.10 The head 1031 of the first connector 103 may be located in the groove 1022b, and the connecting portion 1032 of the first connector 103 may be located in the fifth through hole 1022a, so as to prevent the head 1031 of the first connector 103 from protruding from the surface of the second protruding structure 1022 and ensure the flatness of the structure.

[0086] Optionally, the first connecting member 103 may be a pin. Of course, the first connecting member 103 may also be other structures, such as a screw. The embodiment of the present application does not limit the first connecting member 103, and only needs to ensure that the first connecting member 103 can effectively connect the first protruding structure 1012 and the second protruding structure 1022.

[0087] refer to Figure 8 It can be seen that the shaft mechanism 10 may further include: a sealing member 104. The sealing member 104 may be located between the first rotating assembly 101 and the second rotating assembly 102. Fig.11 The sealing member 104 may have a sixth through hole 104 a. The sixth through hole 104 a may be connected to the first through hole 101 a and the second through hole 102 a respectively, and the sixth through hole 104 a may be used to set the flexible circuit board 20 .

[0088] By providing a seal 104 between the first rotating assembly 101 and the second rotating assembly 102, the sealing performance of the hinge mechanism 10 can be improved to prevent water vapor or dust from entering the first body and the second body of the electronic device through the hinge mechanism 10, thereby ensuring the quality of the electronic device.

[0089] In the embodiment of the present application, one end of the flexible circuit board 20 of the electronic device can pass through the second through hole 102a, the sixth through hole 104a and the first through hole 101a in sequence, and be located on a side of the first rotating component 101 away from the sealing member 104.

The first surface of the third connecting member 106 and the second surface of the third connecting member 106 can be two opposite surfaces.

[0098] Optionally, the first surface of the third connecting member 106 may be bonded to the first surface 1021 a of the second plate 1021 in the second rotating assembly 102 .

[0099] In the embodiment of the present application, the second connector 105 and the third connector 106 can both be made of foam, thereby preventing water vapor or dust from entering the first body and the second body of the electronic device, thereby preventing the components disposed in the first body and the second body from being corroded, and ensuring the quality of the electronic device.
