Description

Technical Field

[0001] The present invention relates to the technical field of mobile terminals, and in particular to a rotating shaft assembly and a terminal device. Background Art

[0002] Terminal devices with foldable screens have become a key area of competition for major terminal manufacturers. To ensure the normal folding function of the terminal devices, a hinge is provided at the position where the screen folds to connect the two middle frames. To prevent the folding part of the screen from being concave when the screen is flattened, a support member that matches the hinge is generally provided at the bottom of the screen. When the screen is folded, the bend will bulge outward, which is easy to interfere with the support member, causing the screen to be unable to fold normally. Therefore, the support member will rotate with the rotation of the hinge to provide a certain amount of avoidance space for the screen. In the related art, the hinge components of terminal devices with foldable screens are numerous and complex in structure, which not only reduces the reliability of the device, but also takes up a lot of space, slows the response of the support member, and easily interferes with the screen. Summary of the Invention

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] The following describes the shaft assembly according to an embodiment of the present invention with reference to the accompanying drawings.

[0035] like Figure 1 As shown, the shaft assembly of the embodiment of the present invention includes: a base 1, a first rotating member 2, a connecting member 3 and a supporting member 4.

[0036] One end of the first rotating member 2 (such as Figure 1 The left end of the first rotating member 2 is rotatably connected to the base 1, and the connecting member 3 has a first supporting surface 31. The first supporting surface 31 refers to Figure 2 The upper surface of the middle connecting member 3, the connecting member 3 and the other end of the first rotating member 2 (such as Figure 1 The right end of the first rotating member 2 is rotatably connected, and the support member 4 has a second supporting surface 41. The second supporting surface 41 refers to Figure 2 The upper surface of the middle support member 4, one end of the support member 4 (such as Figure 1The right end of the middle support member 4 is rotatably connected to the connecting member 3. During the rotation process, the first rotating member 2 can drive the support member 4 to rotate between the first position and the second position through the connecting member 3, and the rotation direction of the first rotating member 2 relative to the base 1 is consistent with the rotation direction of the support member 4 relative to the connecting member 3. In the first position, the first supporting surface 31 and the second supporting surface 41 are located in the same plane. In the second position, the extension surface of the first supporting surface 31 intersects with the extension surface of the second supporting surface 41.

[0037] It can be understood that the first support surface 31 on the connecting member 3 and the second support surface 41 on the supporting member 4 are both used to support the screen. In the first position, Figure 2 As shown, the first support surface 31 and the second support surface 41 are located in the same plane, which means that the screen is in a flat state, and the support member 4 is raised to support the screen; in the second position, as shown Figure 3 As shown, the extension surface of the first support surface 31 intersects with the extension surface of the second support surface 41, which means that the screen is in a folded state, and the support member 4 is folded to the left to make corresponding space for the screen to avoid relative interference between the support member 4 and the screen, thereby ensuring the normal folding function of the terminal device.

[0038] Therefore, the first position refers to a state where the support member 4 is raised and supports the screen, and the second position refers to a state where the support member 4 is retracted and avoids the screen.

[0039] For example, the rotation direction of the first rotating member 2 relative to the base 1 is consistent with the rotation direction of the support member 4 relative to the connecting member 3. It should be understood that when the support member 4 changes from the first position to the second position, Figure 2 and Figure 3 As shown, the first rotating member 2 deflects counterclockwise relative to the base 1 , and the supporting member 4 deflects counterclockwise relative to the connecting member 3 .

[0040] Specifically, if Figure 1 and Figure 2 As shown, the left end of the first rotating member 2 is rotatably connected to the base 1, the connecting member 3 is rotatably connected to the right end of the first rotating member 2, the first supporting surface 31 is the upper surface of the connecting member 3, the second supporting surface 41 is the upper surface of the supporting member 4, and the right end of the supporting member 4 is rotatably connected to the connecting member 3. When the rotating shaft assembly changes from the first position (supporting state) to the second position (folding state) (that is, from Figure 2 The state changes to Figure 3 ), the base 1 is stationary, the first rotating member 2 deflects counterclockwise relative to the base 1, the first rotating member 2 drives the connecting member 3 to deflect counterclockwise, thereby driving the supporting member 4 to deflect counterclockwise relative to the connecting member 3.

[0041] The hinge assembly of the embodiment of the present invention is provided with a support member 4 at the folding part of the screen, which avoids the screen from sinking at the folding part when the screen is flattened, ensures the normal folding function of the terminal device, and provides avoidance space for the screen. During the folding process of the screen, the screen and the support member 4 at the bending part will not interfere with each other, thereby improving the feasibility of screen folding. Moreover, the structure of the hinge assembly is simple and compact, the space occupancy rate is low, and it can adapt well to the changes of the screen without causing pulling and squeezing to the screen.

[0042] In some embodiments, as Figure 1 As shown, it also includes a second rotating member 5, one end of the second rotating member 5 (as shown Figure 1 The left end of the second rotating member 5) is rotatably connected to the base 1, and the rotation center of the second rotating member 5 is different from the rotation center of the first rotating member 2. The other end of the second rotating member 5 (such as Figure 1 The right end of the second rotating member 5 is slidably connected to the connecting member 3, and the connecting member 3 drives the supporting member 4 to rotate through the second rotating member 5.

[0043] Specifically, if Figure 1 and Figure 2 As shown, the left end of the second rotating member 5 is rotatably connected to the base 1, and the rotation center of the second rotating member 5 is located below the rotation center of the first rotating member 2. The right end of the second rotating member 5 is slidably connected to the connecting member 3, and the connecting member 3 drives the support member 4 to rotate through the second rotating member 5. When the first rotating member 2 deflects counterclockwise relative to the base 1, the second rotating member 5 also deflects counterclockwise relative to the base 1. At the same time, relative sliding occurs between the second rotating member 5 and the connecting member 3, causing the support member 4 to deflect counterclockwise relative to the connecting member 3, thereby achieving the folding of the shaft assembly.

[0044] Further, if Figure 1 As shown, one end of the second rotating member 5 (as Figure 1 A first connecting portion 52 is provided at the left end of the second rotating member 5, and a second connecting portion 13 corresponding to the first connecting portion 52 is provided on the base 1. The first connecting portion 52 and the second connecting portion 13 are rotatably matched, and the first connecting portion 52 is a pin shaft or a pin hole.

[0045] It should be understood that there is a pin feature between the base 1 and the second rotating member 5, and the pin feature is the rotatable fit between the first connecting portion 52 and the second connecting portion 13, so as to achieve the effect that the base 1 and the second rotating member 5 can rotate relative to each other.

[0046] Specifically, if Figure 1 As shown, the first connecting portion 52 is a pin, and the pin is along Figure 1 The first connecting portion 52 is located at the left end of the second rotating member 5. The second connecting portion 13 is a pin hole. Figure 1The first connecting portion 52 is inserted into the second connecting portion 13, and the first connecting portion 52 is rotatable along the central axis of the first connecting portion 52 in the second connecting portion 13. In some embodiments, as Figures 1 to 3 As shown, the connecting member 3 is provided with a first groove 32 and a first through hole 36 communicating with the first groove 32. One end of the second rotating member 5 (as shown in FIG. Figure 2 The right end of the second rotating member) along the length direction of the second rotating member 5 (such as Figure 2 The left and right directions in Figure 3 The first engaging portion 33 is provided in the first groove 32, and the second rotating member 5 is provided with a third engaging portion 51 corresponding to the first engaging portion 33. The support member 4 is provided with a second engaging portion 42 corresponding to the first engaging portion 33. The third engaging portion 51 and the second engaging portion 42 on the support member 4 are both engaged with the first engaging portion 33.

[0047] Alternatively, as Figure 1 As shown, the first meshing portion 33 is a gear, rotatably connected to the first groove 32 via a shaft arranged in the front-to-back direction. The third meshing portion 51 is a rack formed on the second rotating member 5. The third meshing portion 51 is located on the upper surface of the second rotating member 5, below the first meshing portion 33, and meshes with the first meshing portion 33. The second meshing portion 42 functions similarly to a partial gear. The second meshing portion 42 is located at the right end of the support member 4, above the first meshing portion 33, and is constantly meshed with the first meshing portion 33.

[0048] Specifically, if Figures 1 to 3 As shown, the first groove 32 is formed on the upper surface of the connecting member 3, the left end of the first groove 33 passes through the left surface of the connecting member 3, and the first groove 32 extends from the left end of the connecting member 3 to the right end of the connecting member 3. The first through hole 36 passes through the right surface of the connecting member 3 and extends from the right end of the connecting member 3 to the left end of the connecting member 3 to communicate with the first groove 36. The right end of the second rotating member 5 is along the length direction of the second rotating member 5 (as shown in FIG. Figure 2 The first groove 32 and the first through hole 36 are slidably disposed in the first groove 32 and the first through hole 36 (in the left and right directions).

[0049] When the support member 4 is in the first position, Figure 2 As shown, the first engaging portion 33 is engaged with the third engaging portion 51. When the first rotating member 2 deflects counterclockwise, the second rotating member 5 and the connecting member 3 slide relative to each other, and the second rotating member 5 drives the first engaging portion 33 to rotate. The first engaging portion 33 rotates and drives the support member 4 to deflect inward and retract, thereby causing the support member 4 to deflect from the first position to the second position, completing the folding of the shaft assembly.

[0050] When the support member 4 is in the second position, Figure 3 As shown, the first meshing portion 33 and the third meshing portion 51 are disengaged from each other. When the first rotating member 2 deflects clockwise, the second rotating member 5 and the connecting member 3 slide relative to each other. The third meshing portion 51 on the second rotating member 5 gradually approaches the first meshing portion 33 and meshes with the first meshing portion 33, thereby driving the first meshing portion 33 to rotate. The first meshing portion 33 rotates and drives the support member 4 to deflect outward and rise. The support member 4 deflects from the second position to the first position, so that the support member 4 rises to support the screen.

[0051] Therefore, the hinge assembly of this embodiment of the present invention has a high transmission speed. The third engaging portion 51 on the second rotating member 5 allows the support member 4 to quickly make room for the screen in the initial folded state. When the space is maximized, the third engaging portion 51 disengages. Conversely, when the device is nearly flattened, the third engaging portion 51 reengages the first engaging portion 33, providing fast and stable support for the screen, effectively adapting to changes in the screen's position without causing any strain or pressure on the screen.

[0052] In some embodiments, as Figures 1 to 3 As shown, the connecting member 3 is further provided with a second groove 34 , and one end of the first rotating member 2 is rotatably disposed in the second groove 34 .

[0053] Specifically, if Figure 1 As shown, the second groove 34 is located in front of the first groove 32. The second groove 34 is formed on the upper surface of the connecting member 3. The left end of the second groove 34 passes through the left surface of the connecting member 3 and extends from the left end to the right end of the connecting member 3. The right end of the first rotating member 2 is rotatably disposed in the second groove 34. The provision of the second groove 34 on the connecting member 3 allows the deflection of the first rotating member 2 to occur within the second groove 34, further reducing the space occupied by the shaft assembly and making the shaft assembly structure more compact.

[0054] Furthermore, a third connecting portion 22 is provided at one end of the first rotating member 2, and a fourth connecting portion 37 corresponding to the third connecting portion 22 is provided on the connecting member 3. The third connecting portion 22 and the fourth connecting portion 37 are rotatably matched via a pin shaft.

[0055] It can be understood that the relative rotation between the first rotating member 2 and the connecting member 3 is achieved by the matching relationship between the third connecting portion 22 and the fourth connecting portion 37 .

[0056] Specifically, if Figure 1 As shown, the third connecting portion 22 is located at the right end of the first rotating member 2. Figure 1The pin hole is arranged in the front-back direction, and the fourth connecting portion 37 is located in the second groove 34. The fourth connecting portion 37 is along Figure 1 The pin holes are arranged in the front-to-back direction, and the positions of the third connecting part 22 and the fourth connecting part 37 correspond to each other. The pin shaft is inserted into the third connecting part 22 and the fourth connecting part 37 to realize the relative rotation between the first rotating member 2 and the connecting member 3.

[0057] In some embodiments, as Figures 1 to 3 As shown, the connecting member 3 also has an inclined surface 35 connected to the first supporting surface 31. The inclined surface 35 is located on the side of the first supporting surface 31 adjacent to the base 1. The support member 4 is connected to the side of the inclined surface 35 adjacent to the first supporting surface 31. In the second position, the support member 4 is against the inclined surface 35.

[0058] It is understandable that if Figure 3 As shown, in the second position, the support member 4 is retracted and abuts against the inclined surface 35, thereby leaving a folding space for the screen.

[0059] Specifically, if Figure 1 As shown, the inclined surface 35 is located on the left side of the first support surface 31, and the support member 4 is connected to the right side of the inclined surface 35. In the second position, the lower surface of the support member 4 abuts against the inclined surface 35 of the connecting member 3. During the process of the support member 4 deflecting from the first position to the second position, when the lower surface of the support member 4 abuts against the inclined surface 35 of the connecting member 3, the third engaging portion 51 disengages from the first engaging portion 33.

[0060] Further, if Figure 1 As shown, the support member 4 is provided with a fifth connecting portion 44, and the connecting member 3 is provided with a sixth connecting portion 38 corresponding to the fifth connecting portion 44. The fifth connecting portion 44 and the sixth connecting portion 38 are rotatably matched through a pin shaft.

[0061] It can be understood that the relative rotation between the support member 4 and the connecting member 3 is achieved by the matching relationship between the fifth connecting portion 44 and the sixth connecting portion 38 .

[0062] Specifically, if Figure 1 As shown, the fifth connecting portion 44 is located at the right end of the support member 4, and the fifth connecting portion 44 is along Figure 1 The pin holes are arranged in the front and rear directions, and the sixth connecting portion 38 is located at the upper part of the connecting member 3. The sixth connecting portion 38 is along Figure 1 The pin holes are set in the front-to-back direction, the sixth connecting part 38 passes through the connecting member 3, the positions of the fifth connecting part 44 and the sixth connecting part 38 correspond to each other front-to-back, and the relative rotation between the support member 4 and the connecting member 3 is achieved by inserting the pin shaft into the fifth connecting part 44 and the sixth connecting part 38.

[0063] In some embodiments, as shown in the figure, a first notch 43 for avoiding the first rotating member 2 is provided at a position on one side of the support member 4 adjacent to the base 1 and opposite to the first rotating member 2 .

[0064] It is understandable that if Figure 4 As shown, when the rotating shaft assembly is folded, part of the first rotating member 2 is located in the first notch 43 , which solves the problem of interference between the first rotating member 2 and the supporting member 4 during the rotation process.

[0065] Specifically, if Figure 1 As shown, a first notch 43 is provided on the left side of the support member 4. The path of the first notch 43 is set along the length direction of the support member 4. Part of the first rotating member 2 can pass through the first notch 43, so that during the process of the support member 4 changing from the first position to the second position or from the second position to the first position, the deflection of the first rotating member 2 and the support member 4 will not interfere with each other.

[0066] In some embodiments, as Figure 1 As shown, the upper surface of the base 1 has a third supporting surface 11 . In the first position, the third supporting surface 11 , the first supporting surface 31 and the second supporting surface 41 are located in the same plane.

[0067] Specifically, if Figure 2 As shown, the first support surface 31 on the connecting member 3, the second support surface 41 on the supporting member 4 and the third support surface 11 on the base 1 are located in the same plane, jointly supporting the screen of the terminal device, thereby better supporting the screen and further reducing the probability of the screen being sunken and bent.

[0068] In some embodiments, as Figures 1 to 4 As shown, an arc-shaped guide portion 21 is provided at one end of the first rotating member 2 , and an arc-shaped shaft groove 12 corresponding to the guide portion 21 is provided on the base 1 , and the guide portion 21 is rotatably fitted in the shaft groove 12 .

[0069] Specifically, if Figure 1 As shown, the left end of the first rotating member 2 is provided with an arc-shaped guide portion 21, the arc of the guide portion 21 is semicircular, and the front end of the base 1 is provided with a semicircular shaft groove 12 arranged along the front and rear directions. The guide portion 21 can be rotatably engaged in the shaft groove 12, and the guide portion 21 rotates around the axis of the shaft groove 12.

[0070] The rotational cooperation between the guide portion 21 and the shaft groove 12 makes the process of raising and retracting the support member 4 smoother and gentler.

[0071] Further, if Figure 1 As shown, the width direction of the base 1 (such as Figure 1 A second notch 14 is provided at the end portion (in the left and right directions) for avoiding the first rotating member 2.

[0072] It is understandable that if Figure 1 and 2 As shown, in the first position, the first rotating member 2 is tilted downward, and part of the first rotating member 2 is located in the second notch 14. The lower surface of the first rotating member 2 is against the cutting surface of the base 1 where the second notch 14 is opened. The second notch 14 provides an escape space for the first rotating member 2.

[0073] Specifically, if Figure 1 As shown, the second notch 14 is opened on a side of the shaft groove 12 close to the connecting member 3 , and the second notch 14 is communicated with the shaft groove 12 .

[0074] In some embodiments, there are two first rotating members 2 , two connecting members 3 and two supporting members 4 , and the two first rotating members 2 , the two connecting members 3 and the two supporting members 4 are respectively arranged on two sides of the base 1 in the width direction.

[0075] It can be understood that a first rotating member 2, a connecting member 3 and a supporting member 4 located on one side in the width direction of the base 1 are a first group of supporting mechanisms, and a first rotating member 2, a connecting member 3 and a supporting member 4 located on the other side in the width direction of the base 1 are a second group of supporting mechanisms. The first group of supporting mechanisms and the second group of supporting mechanisms jointly support the screen on the terminal device to improve the stability of the hinge assembly.

[0076] A terminal device according to another embodiment of the present invention includes the hinge assembly described in any one of the above embodiments.

[0077] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0078] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0079] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0080] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary.
