[0071] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0072] In related technologies, the hinge structure of a foldable mobile terminal includes a bracket, a first movable member, and a second movable member. The terminal device includes a device housing, which comprises a first shell and a second shell. The first shell is connected to the first movable member, and the second shell is connected to the second movable member. Multiple gears mesh to drive the first and second movable members, enabling synchronous movement of the first and second shells. However, due to the inherent structural limitations of the gears, their radial dimensions are relatively large, resulting in a thicker hinge structure, which is detrimental to the slim and lightweight design of the terminal device.

[0073] The hinge assembly of this disclosure is used in a terminal device. The terminal device further includes a device housing and a display panel. The device housing includes a first housing and a second housing, both of which are connected to the hinge assembly. The hinge assembly enables simultaneous movement of the first and second housings, as well as the folding and unfolding of the display panel, thereby realizing the folding and unfolding of the terminal device. The display panel is a foldable flexible display panel.

[0074] The hinge assembly 100 of the present invention is described below according to an embodiment of the present invention.

[0075] like Figures 1 to 7 As shown, the hinge assembly 100 of this embodiment includes a bracket 1, a movable member 2, a first movable member 31, a second movable member 32, a first support member 41, and a second support member 42.

[0076] Moving part 2 along the first direction (e.g.) Figure 1 The first movable member 31 and the second movable member 32 are movably mounted on the support 1 in the vertical direction shown. Each of them is pivotally mounted on the support 1, and the pivot axis of the first movable member 31 and the pivot axis of the second movable member 32 are both along the first direction (e.g., vertical direction shown). Figure 1 (Extends in the vertical direction as shown).

[0077] The first movable member 31 and the second movable member 32 are both movably connected to the moving member 2. The moving member 2 is used to drive the first movable member 31 and the second movable member 32 to swing simultaneously by moving along the first direction.

[0078] The first movable member 31 is connected to the first housing 201 of the terminal device, and the second movable member 32 is connected to the second housing 202 of the device housing, such that each of the first housing 201 and the second housing 202 is swayable relative to the support 1. When the first housing 201 sways, the first movable member 31 sways with the first housing 201, and when the second housing 202 sways, the second movable member 32 sways with the second housing 202; similarly, when the first movable member 31 sways, the first housing 201 sways with the first movable member 31, and when the second movable member 32 sways, the second housing 202 sways with the second movable member 32.

[0079] Both the first movable component 31 and the second movable component 32 are movably connected to the movable component 2, and the movable component 2 moves along the first direction ( Figure 1The movement (as shown in the up-down direction) allows for the simultaneous swinging of the first housing 201 connected to the first movable member 31 and the second housing 202 connected to the second movable member 32. For example, when the first movable member 31 swings, the driving member 2 moves in the up-down direction, thereby causing the second movable member 32 to swing, achieving simultaneous swinging of the first and second movable members 31; when the second movable member 32 swings, the driving member 2 moves in the up-down direction, thereby causing the first movable member 31 to swing, achieving simultaneous swinging of the first and second movable members 31. This, in turn, enables the simultaneous swinging of the first housing connected to the first movable member 31 and the second housing connected to the second movable member 32.

[0080] In this embodiment of the hinge assembly 100, the movable member 2 only needs to satisfy the requirement of being able to move along a first direction, and converting the swinging of the first movable member 31 into the movement of the movable member 2 along the first direction, and converting the movement of the movable member 2 along the first direction into the swinging of the second movable member 32. In short, the hinge assembly 100 of this embodiment of the present disclosure utilizes the movement of the movable member 2 to achieve the simultaneous swinging of the first movable member 31 and the second movable member 32. Compared with related technologies that utilize gear structures to achieve the simultaneous swinging of the first and second movable members, this significantly reduces the impact of the movable member 2 in the third direction (…). Figure 1 The dimensions (shown in the front-back direction) are adjusted to reduce the overall thickness of the hinge assembly 100, facilitating a thinner and lighter design for terminal devices incorporating the hinge assembly 100. The third direction is perpendicular to the first direction.

[0081] Furthermore, the first support member 41 is swayably mounted on the first movable member 31, and the second support member 42 is swayably mounted on the second movable member 32. The sway axis of the first support member 41 and the sway axis of the second support member 42 are both along the first direction (e.g., Figure 1 (Extends in the vertical direction as shown).

[0082] Both the first support member 41 and the second support member 42 are used to support the display panel of the terminal device. For example, the display panel includes a first display portion and a second display portion, the first support member 41 is used to support the first display portion, and the second support member 42 is used to support the second display portion. For example, when the terminal device is in the unfolded state, the first support member 41 swings with the first movable member 31 to... Figure 2 As shown, the second support member 42 swings with the second movable member 32 to... Figure 2The state shown is such that the first support member 41 supports the first display portion of the display panel, and the second support member 42 supports the second display portion of the display panel. When the terminal device is folded, in addition to swinging a first preset angle (e.g., 90°) with the first movable member 31 and the second movable member 32 respectively, the first support member 41 and the second support member 42 can also swing a second preset angle (e.g., 10°) respectively under the interaction of the first and second display portions of the display panel. At this time (e.g.... Figure 3 As shown, a teardrop-shaped accommodating space is formed between the first support member 41, the second support member 42, the first movable member 31, and the second movable member 32 to better accommodate the bent part of the display panel, avoid the formation of obvious creases in the bent part of the display panel, and help improve the user experience and extend the service life of the display panel.

[0083] Therefore, the hinge assembly 100 of the present disclosure has advantages such as thinness.

[0084] The terminal device having the hinge assembly 100 of the present disclosure has advantages such as thinness and long service life.

[0085] To make the technical solution of this application easier to understand, the following describes the technical solution of this application further, taking the first direction being consistent with the up-down direction as an example, the second direction being consistent with the left-right direction as an example, and the third direction being consistent with the front-back direction as an example. The up-down direction, left-right direction, and front-back direction are as follows: Figure 1 As shown.

[0086] For example, the movable member 2 can move vertically on the support 1. Both the first movable member 31 and the second movable member 32 are oscillatingly connected to the support 1, with the oscillation axis of both the first movable member 31 and the second movable member 32 extending vertically. The first movable member 31 and the second movable member 32 are spaced apart horizontally; for example, the first movable member 31 is located to the left of the second movable member 32. The first movable member 31 and the second movable member 32 can oscillate horizontally, and both are movably connected to the movable member 2.

[0087] The first support member 41 and the second support member 42 are spaced apart in the left-right direction. For example, the first support member 41 is located to the left of the second support member 42. The swing axis of the first support member 41 and the swing axis of the second support member 42 both extend in the up-down direction, and the first support member 41 and the second support member 42 can swing in the front-back direction.

[0088] Hinge assembly 100 from folded state ( Figure 3 (As shown) Move to the unfolded state ( Figure 2During the process shown, under the action of the first movable member 31, the second movable member 32 and the moving member 2, the first housing 201 and the second housing 202 swing backward in opposite directions at the same time; the first support member 41 and the second support member 42 swing backward in opposite directions at the same time, and finally the display panel and the device housing are fully unfolded. At this time, the first display part of the display panel is supported by the first support member 41 and the second display part of the display panel is supported by the second support member 42.

[0089] Hinge assembly 100 from the unfolded state ( Figure 2 (As shown) Move to the folded state ( Figure 3 During the process shown, under the action of the first movable member 31, the second movable member 32 and the moving member 2, the first housing 201 and the second housing 202 swing forward in opposite directions at the same time; the first support member 41 and the second support member 42 swing forward in opposite directions at the same time, and finally the display panel and the device housing are folded up. At this time, the bent part of the display panel is located in the "teardrop" shaped receiving space formed by the first movable member 31, the second movable member 32, the first support member 41 and the second support member 42.

[0090] In some embodiments, the movable member 2 has a first guide portion 21, and the first movable member 31 has a second guide portion 311, the first guide portion 21 being along a first direction (e.g., Figure 1 (As shown in the up-down direction) can be movably engaged with the second guide part 311.

[0091] The moving member 2 has a third guide portion 22, and the second movable member 32 has a fourth guide portion (not shown in the figure). The third guide portion 22 is along a first direction (e.g., Figure 1 (As shown in the up-down direction) can be movably engaged with the fourth guide section.

[0092] For example, such as Figure 1 As shown, the first guide part 21 and the second guide part 311 cooperate with each other, so that when the first movable member 31 swings, it can drive the moving member 2 to move, or when the moving member 2 moves, it can drive the first movable member 31 to swing.

[0093] The third guide part 22 and the fourth guide part cooperate with each other. Thus, when the second movable member 32 swings, it can drive the moving member 2 to move, or when the moving member 2 moves, it can drive the second movable member 32 to swing.

[0094] When the first movable member 31 swings, it can drive the movable member 2 to move, which in turn drives the second movable member 32 to swing; or, when the second movable member 32 swings, it can drive the movable member 2 to move, which in turn drives the first movable member 31 to swing.

[0095] Therefore, through the cooperation of the first guide part 21 and the second guide part 311, and the cooperation of the third guide part 22 and the fourth guide part, the movement of the moving part 2 can be guided, so that the moving part 2 moves along a preset path parallel to the first direction, which is beneficial to improving the reliability of the hinge assembly 100.

[0096] In some embodiments, one of the first guide portion 21 and the second guide portion 311 is along a first direction (e.g., ...). Figure 1 The first arc-shaped protrusion extends in the vertical direction (as shown), and the other of the first guide portion 21 and the second guide portion 311 is along the first direction (such as...). Figure 1 The first arc-shaped groove extends in the vertical direction (as shown).

[0097] For example, the projections of the outer periphery of the first guide portion 21 and the outer periphery of the second guide portion 311 onto a plane perpendicular to the front-rear direction are curved. Figure 1 As shown, the first guide portion 21 is a first arc-shaped protrusion, and the second guide portion 311 is a first arc-shaped groove that mates with the first arc-shaped protrusion; or, the first guide portion 21 is a first arc-shaped groove, and the second guide portion 311 is a first arc-shaped protrusion that mates with the first arc-shaped groove. The first arc-shaped protrusion is movably disposed within the first arc-shaped groove in the vertical direction. The first arc-shaped protrusion has a first end and a second end opposite to each other in a first direction, and the first end and the second end are arranged along a second direction.

[0098] Through the cooperation of the first arc-shaped protrusion and the first arc-shaped groove, the first movable member 31 can drive the movable member 2 to move when it swings, or the movable member 2 can drive the first movable member 31 to swing when it moves. Therefore, the structure of the first guide part 21 and the second guide part 311 is simple and easy to process and manufacture.

[0099] In some embodiments, one of the third guide portion 22 and the fourth guide portion is along a first direction (e.g., Figure 1 The second arc-shaped protrusion extends in the vertical direction (as shown), and the other of the third guide portion 22 and the fourth guide portion extends along the first direction (as shown). Figure 1 The second arc-shaped groove extends in the vertical direction (as shown).

[0100] For example, the projections of the outer periphery of the third guide portion 22 and the outer periphery of the fourth guide portion onto a plane perpendicular to the front-rear direction are curved. Figure 1As shown, the third guide portion 22 is a second arc-shaped protrusion, and the fourth guide portion is a second arc-shaped groove that mates with the second arc-shaped protrusion; or, the third guide portion 22 is a second arc-shaped groove, and the fourth guide portion is a second arc-shaped protrusion that mates with the second arc-shaped groove. The second arc-shaped protrusion is movably disposed within the second arc-shaped groove in the vertical direction. The second arc-shaped protrusion has a first end and a second end opposite to each other in the first direction, and the first end and the second end are arranged along the second direction.

[0101] Through the cooperation of the second arc-shaped protrusion and the second arc-shaped groove, the second movable member 32 can drive the moving member 2 to move when it swings, or the moving member 2 can drive the second movable member 32 to swing when it moves. Therefore, the third guide part 22 and the fourth guide part have simple structures and are easy to process and manufacture.

[0102] In some embodiments, the first movable member 31 and the second movable member 32 are along a second direction (e.g., Figure 1 Arranged in the left-right direction (as shown), the first movable member 31 and the second movable member 32 are in the third direction (e.g., in the left-right direction). Figure 1 In the front-back direction shown, it is located on the same side as the moving part 2, in the second direction (such as...). Figure 1 The left and right directions shown are perpendicular to the first direction (e.g., the left and right directions shown are perpendicular to the first direction). Figure 1 (as shown in the up and down directions), the third direction is perpendicular to each of the second and first directions.

[0103] For example, such as Figures 1 to 5 As shown, the first movable member 31 is located to the left of the second movable member 32, and both the first movable member 31 and the second movable member 32 are located in front of the movable member 2.

[0104] Therefore, the first movable member 31 and the second movable member 32 do not overlap in the front-back direction (thickness direction of the hinge assembly 100), which is beneficial to further reduce the thickness of the hinge assembly 100 and further beneficial to the thin and light design of the terminal device having the hinge assembly 100.

[0105] In some embodiments, the bracket 1 has a first clearance portion (not shown in the figure), and the movable member 2 is disposed within the first clearance portion.

[0106] For example, the first clearance portion can be a groove, and the shape of the first clearance portion is adapted to the shape of the movable member 2, so that the movable member 2 can be embedded in the first clearance portion. It should be noted that, in the first direction, the size of the first clearance portion is larger than the size of the movable member 2, so that the movable member 2 can move in the first direction within the first clearance portion 11.

[0107] Therefore, at least a portion of the movable member 2 is located within the bracket 1 in the front-rear direction, which is beneficial to further reduce the thickness of the hinge assembly 100 and further facilitates the thinner and lighter design of the terminal device having the hinge assembly 100.

[0108] In some embodiments, the first guide portion 21 and the third guide portion 22 are along a first direction (e.g., Figure 1 The vertical (as shown) interval settings.

[0109] For example, such as Figure 1 As shown, the first guide section 21 is above the third guide section 22. That is, the first guide section 21 and the third guide section 22 are staggered in the vertical direction.

[0110] Therefore, while ensuring that the moving part 2 has sufficient structural strength, the size of the moving part 2 in the second direction can be effectively reduced, making the overall structure of the hinge assembly 100 more compact, and utilizing the thin and light design of the terminal device with the hinge assembly 100.

[0111] In some embodiments, the movable member 2 has a fifth guide portion 23, and the bracket 1 has a sixth guide portion, the fifth guide portion 23 being along a first direction (e.g., Figure 1 (As shown in the up-down direction) can slide and engage with the sixth guide part.

[0112] Specifically, the fifth guide portion 23 and the sixth guide portion are connected and can slide relative to each other. The fifth guide portion 23 and the sixth guide portion have many structures. For example, the fifth guide portion 23 and the sixth guide portion are engaged by snap-fit ​​or hook-hook, thereby realizing the connection between the fifth connecting portion and the sixth connecting portion. Furthermore, the fifth guide portion 23 and the sixth guide portion extend along the vertical direction so that the fifth guide portion 23 and the sixth guide portion can slide relative to each other in the vertical direction.

[0113] Therefore, the cooperation of the fifth guide portion 23 and the sixth guide portion can guide the movement of the moving member 2, thereby enabling the moving member 2 to move along a preset path parallel to the first direction, which helps to improve the reliability of the hinge assembly 100. In some embodiments, there are multiple fifth guide portions 23 and multiple sixth guide portions, with each fifth guide portion 23 cooperating with the corresponding sixth guide portion.

[0114] For example, such as Figure 1 As shown, the movable part 2 has two fifth guide parts 23, and the bracket 1 has two sixth guide parts. Each fifth guide part 23 can cooperate with the corresponding sixth guide part.

[0115] Therefore, by cooperating with multiple fifth guide parts 23 and multiple sixth guide parts, the moving part 2 moves more smoothly, which helps to improve the stability of the hinge assembly 100.

[0116] It is understandable that the fifth guide section 23 and the sixth guide section can also be 3, 4, etc.

[0117] Of course, in some other embodiments, one fifth guide portion 23 and one sixth guide portion may also be provided.

[0118] In some embodiments, the plurality of fifth guide portions 23 are along a second direction (e.g. Figure 1 The left and right directions are shown in the interval settings.

[0119] For example, such as Figure 1 As shown, a fifth guide portion 23 is provided on the left and right sides of the movable part 2, so that the left and right sides of the movable part 2 can slide smoothly, and the multiple fifth guide portions 23 can ensure that the movable part 2 has sufficient structural strength, thereby improving the stability of the hinge assembly 100.

[0120] In some embodiments, one of the fifth guide portion 23 and the sixth guide portion is along a first direction (e.g. Figure 1 The third arc-shaped protrusion extends in the vertical direction (as shown), and the other of the fifth guide portion 23 and the sixth guide portion extends along the first direction (as shown). Figure 1 The third arc-shaped groove extends in the vertical direction (as shown).

[0121] The fifth guide portion 23 is a straight, third arc-shaped protrusion extending in the first direction, and the sixth guide portion is a straight, third arc-shaped groove extending in the first direction; or the sixth guide portion is a third arc-shaped protrusion, and the fifth guide portion 23 is a third arc-shaped groove. The third arc-shaped protrusion is movably disposed within the third arc-shaped groove in the vertical direction.

[0122] Therefore, the fifth guide portion 23 and the sixth guide portion have simple structures and are easy to manufacture. In some embodiments, the bracket 1 has a first mating portion 13, and the first movable member 31 has a second mating portion 312, which is rotatably mated with the first mating portion 13 along the swing axis of the first movable member 31.

[0123] For example, such as Figure 1 As shown, the first mating part 13 is on the left side of the bracket 1, and the second mating part 312 is on the right side of the first movable member 31. The first mating part 13 and the second mating part 312 are connected and can rotate relative to each other. The structure of the first mating part 13 and the second mating part 312 can be varied. For example, the first mating part 13 can be a rotating shaft, and the second mating part 312 can be a hole. Alternatively, the first mating part 13 can be an arc-shaped protrusion, and the second mating part 312 can be an arc-shaped groove.

[0124] Therefore, through the cooperation of the first mating part 13 and the second mating part 312, the rotation of the first movable part 31 can be guided, so that the first movable part 31 can swing relative to the moving part 2, which is beneficial to improving the reliability of the hinge assembly 100.

[0125] In some embodiments, the bracket 1 has a third mating part (not shown in the figure), and the second movable member 32 has a fourth mating part 322, which is rotatably mated with the second mating part 312 along the swing axis of the second movable member 32.

[0126] For example, such as Figure 1 As shown, the third mating part is on the right side of the bracket 1, and the fourth mating part 322 is on the left side of the second movable member 32. The third mating part and the fourth mating part 322 are connected and can rotate relative to each other. The structure of the third mating part and the fourth mating part 322 can be varied. For example, the third mating part can be a rotating shaft, and the fourth mating part 322 can be a hole. Alternatively, the third mating part can be an arc-shaped protrusion, and the fourth mating part 322 can be an arc-shaped groove.

[0127] Therefore, through the cooperation of the third and fourth mating parts 322, the rotation of the second movable member 32 can be guided, so that the second movable member 32 can swing relative to the moving member 2, which is beneficial to improving the reliability of the hinge assembly 100.

[0128] In some embodiments, one of the first mating part 13 and the second mating part 312 is along a second direction (e.g., ...). Figure 1 The fourth arc-shaped protrusion extends in the left-right direction (as shown), and the other of the first mating part 13 and the second mating part 312 is along the second direction (as shown). Figure 1 The fourth arc-shaped groove extends in the left-right direction (as shown). The fourth arc-shaped protrusion is movably disposed within the fourth arc-shaped groove in the left-right direction.

[0129] For example, such as Figure 1 As shown, both the fourth arc-shaped protrusion and the fourth arc-shaped groove extend in the left-right direction so that the first movable member 31 can swing relative to the bracket 1 in the left-right direction. The first mating part 13 is the fourth arc-shaped protrusion and the second mating part 312 is the fourth arc-shaped groove, or the first mating part 13 is the fourth arc-shaped groove and the second mating part 312 is the fourth arc-shaped protrusion.

[0130] Therefore, by utilizing the fourth arc-shaped protrusion and the fourth arc-shaped groove, the first movable part 31 can swing smoothly relative to the support 1. Moreover, the structure of the fourth arc-shaped protrusion and the fourth arc-shaped groove is simple and easy to process and manufacture.

[0131] In some embodiments, one of the third mating portion and the fourth mating portion 322 is along the second direction (e.g., ...). Figure 1 The fifth arc-shaped protrusion extending in the left-right direction (as shown), the other of the third and fourth mating parts 322 is along the second direction (as shown). Figure 1 The fifth arc-shaped groove extends in the left and right directions (as shown).

[0132] For example, such as Figure 1As shown, both the fifth arc-shaped protrusion and the fifth arc-shaped groove extend in the left-right direction, so that the second movable member 32 can swing relative to the bracket 1 in the left-right direction. The third mating part is the fifth arc-shaped protrusion, and the fourth mating part 322 is the fifth arc-shaped groove, or the third mating part is the fifth arc-shaped groove, and the fourth mating part 322 is the fifth arc-shaped protrusion. The fifth arc-shaped protrusion is movably disposed within the fifth arc-shaped groove in the left-right direction.

[0133] Therefore, by utilizing the fifth arc-shaped protrusion and the fifth arc-shaped groove, the second movable part 32 can swing smoothly relative to the support 1. Moreover, the structure of the fifth arc-shaped protrusion and the fifth arc-shaped groove is simple and easy to process and manufacture.

[0134] In some embodiments, the second guide portion 311 and the second mating portion 312 are along a first direction (e.g. Figure 1 The vertical (as shown) interval settings.

[0135] For example, the second guide portion 311 and the second mating portion 312 are arranged in the vertical direction, that is, the second guide portion 311 and the second mating portion 312 are arranged in a direction perpendicular to the front and back direction. This helps to reduce the size of the first moving part 31 in the front and back direction, making the overall structure of the hinge assembly 100 more compact and conducive to the lightweight design of the terminal device.

[0136] In some embodiments, the fourth guide portion and the fourth mating portion 322 are aligned along a first direction (e.g., ...). Figure 1 The vertical (as shown) interval settings.

[0137] For example, the fourth guide portion 321 and the fourth mating portion 322 are arranged in the vertical direction, that is, the fourth guide portion 321 and the fourth mating portion 322 are arranged in a direction perpendicular to the front and back direction. This helps to reduce the size of the second moving part 32 in the front and back direction, making the overall structure of the hinge assembly 100 more compact and conducive to the lightweight design of the terminal device.

[0138] In some embodiments, such as Figures 1 to 5 As shown, the hinge assembly 100 also includes an intermediate support 7, which is located in the second direction (e.g., Figure 1 The intermediate support 7 is located between the first support 41 and the second support 42 in the left-right direction (as shown), and is positioned along a third direction (e.g., in the left-right direction). Figure 1 The intermediate support 7 is movably mounted on the bracket 1 in the front-to-back direction (as shown) so that it can move between the first position and the second position.

[0139] For example, the intermediate support 7 is movable in the front-to-back direction. The first position is located below the second position. The display panel includes a third part. When the intermediate support 7 is in the second position, it supports the third part of the display panel. When the intermediate support 7 is in the first position, the first movable member 31 and the second movable member 32 are in a folded state; when the intermediate support 7 is in the second position, the first movable member 31 and the second movable member 32 are in an unfolded state.

[0140] For example, when the hinge assembly 100 is in the unfolded state, the intermediate support 7 is in the second position. At this time, the intermediate support 7 can contact and support the third part of the display panel. When the hinge assembly 100 is in the folded state, the intermediate support 7 is in the second position so as to provide more space for the folded part of the display panel, thereby improving the user experience of the terminal device with the hinge assembly 100.

[0141] In some embodiments, such as Figure 4 As shown, the intermediate support 7 has a first pushing part 72, and at least one of the first movable part 31 and the second movable part 32 has a second pushing part 73. The second pushing part 73 is used to push the first pushing part 72 in a direction away from the bracket 1, so that at least one of the first movable part 31 and the second movable part 32 drives the intermediate support 7 to move from the first position to the second position.

[0142] For example, the first movable member 31 is provided with a second pushing part 73, or the second movable member 32 is provided with a second pushing part 73, or both the first movable member 31 and the second movable member 32 are provided with second pushing parts 73. Thus, the second pushing part 73 pushes the first pushing part 72, thereby moving the intermediate support member 7 from the first position to the second position, so as to support the display panel with the intermediate support member 7.

[0143] Therefore, the first movable member 31 or the second movable member 32 can be used to easily drive the intermediate support member 7 from the first position to the second position, which helps to simplify the overall structure of the hinge assembly 100 and facilitates the processing and manufacturing of the hinge assembly 100.

[0144] Optionally, the second pushing part 73 and the first pushing part 72 are pushing planes.

[0145] In some embodiments, the hinge assembly 100 further includes a hinge housing 8, which is movably disposed on the support 1 along a third direction to allow the hinge housing 8 to move between a third position and a fourth position.

[0146] Specifically, when the hinge housing 8 is in the third position, the intermediate support 7 is in the first position; when the hinge housing 8 is in the fourth position, the intermediate support 7 is in the second position.

[0147] Specifically, such as Figure 2 As shown, when the hinge assembly 100 is in the unfolded state, the hinge housing 8 is in the third position; when the hinge assembly 100 is in the folded state, the hinge housing 8 is in the fourth position.

[0148] Understandably, when the hinge assembly 100 needs to be unfolded, the hinge housing 8 moves away from the bracket 1. Figure 2 The hinge housing 8 moves forward (inward) to avoid other parts on the hinge assembly 100; when the hinge assembly 100 needs to be folded, the hinge housing 8 moves towards the support 1 (i.e., towards the front ...). Figure 2 (Moves to the rear) to cover the bracket 1 and other components inside the hinge housing 8, preventing the components inside the hinge housing 8 from being exposed.

[0149] Therefore, the hinge assembly 100 of the present disclosure has the advantage of reducing the risk of external leakage of the hinge assembly 100.

[0150] Furthermore, when the hinge assembly 100 is in the unfolded state, the hinge housing 8 is in the third position and the intermediate support 7 is in the first position. In this state, the intermediate support 7 can support the third part of the display panel, allowing the hinge housing 8 to avoid other components on the hinge assembly 100. When the hinge assembly 100 is in the folded state, the hinge cover is in the fourth position and the intermediate support 7 is in the second position. In this state, the intermediate support 7 can provide more space for the display panel, and the hinge housing 8 can conceal components such as the bracket 1 within the hinge housing 8, better meeting user needs.

[0151] In some embodiments, the hinge housing 8 has a third pushing portion 82, and at least one of the first movable member 31 and the second movable member 32 has a fourth pushing portion 83, which is used to push the third pushing portion 82 in a direction away from the support 1, so that at least one of the first movable member 31 and the second movable member 32 drives the hinge housing 8 to move from the third position to the fourth position.

[0152] For example, the first movable member 31 is provided with a fourth pushing part 83, or the second movable member 32 is provided with a fourth pushing part 83, or both the first movable member 31 and the second movable member 32 are provided with a fourth pushing part 83.

[0153] Therefore, the fourth pushing part 83 pushes the third pushing part 82, thereby moving the hinge housing 8 from the third position to the fourth position. This simplifies the overall structure of the hinge assembly 100 and facilitates its manufacturing.

[0154] Optionally, the third jacking part 82 and the fourth jacking part 83 are jacking planes.

[0155] The second position is located in front of the first position, and the fourth position is located behind the third position.

[0156] like Figure 2 As shown, when the hinge assembly 100 switches from the folded state to the unfolded state, the intermediate support 7 moves from the first position to the second position, and the hinge housing 8 moves from the third position to the fourth position, with the intermediate support 7 and the hinge housing 8 moving away from each other in the front-back direction.

[0157] Therefore, the hinge housing 8 can be easily driven to move between the third and fourth positions by using the first movable member 31 or the second movable member 32, which helps to simplify the overall structure of the hinge assembly 100 and facilitates the processing and manufacturing of the hinge assembly 100.

[0158] In some embodiments, the hinge assembly 100 further includes a first magnetic element 71 and a second magnetic element 81. The first magnetic element 71 is disposed on the intermediate support member 7, and the second magnetic element 81 is disposed on the hinge housing 8. The first magnetic element 71 and the second magnetic element 81 can attract each other to drive the intermediate support member 7 to move from a second position to a first position, while simultaneously driving the hinge housing 8 to move from a fourth position to a third position.

[0159] For example, the first magnetic element 71 has a first magnetic pole, the second magnetic element 81 has a second magnetic pole, the first magnetic pole and the second magnetic pole are arranged opposite to each other, the first magnetic pole and the second magnetic pole are opposite magnetic poles (for example, the first magnetic pole is the S pole and the second magnetic pole is the N pole), the first magnetic pole and the second magnetic pole attract each other, driving the intermediate support 7 to move from the second position to the first position and the hinge housing 8 to move from the fourth position to the third position.

[0160] During the folding process of the hinge assembly 100 moving from the unfolded state, there is no interaction force between the first pushing part 72 and the second pushing part 73, and there is no interaction force between the third pushing part 82 and the fourth pushing part 83. The first magnetic element 71 and the second magnetic element 81 attract each other, causing the intermediate support 7 to move from the second position to the first position under the action of magnetic attraction, and at the same time causing the hinge housing 8 to move from the fourth position to the third position under the action of magnetic attraction.

[0161] Therefore, the first magnetic component 71 and the second magnetic component 81 facilitate the movement of the intermediate support 7 from the second position to the first position under magnetic attraction, and the hinge housing 8 moves from the fourth position to the third position under magnetic attraction. The reset structure at the intermediate support 7 and the hinge housing 8 is simple, which facilitates the processing and assembly of the hinge assembly 100.

[0162] The first magnetic component 71 can be fixed to the intermediate support component 7 by means of bonding, snapping, etc., and the second magnetic component 72 can be fixed to the hinge housing 8 by means of bonding, snapping, etc.

[0163] In some embodiments, the first magnetic element 71 and the second magnetic element 81 are along a second direction (e.g., Figure 1 The left and right directions are shown in the interval settings.

[0164] For example, such as Figures 1 to 3 As shown, the first magnetic element 71 is located to the right of the second magnetic element 81, which helps to further reduce the size of the hinge assembly 100 in the front-back direction and further facilitates the thinner and lighter design of the terminal device having the hinge assembly 100.

[0165] Of course, in other embodiments, the first magnetic element 71 and the second magnetic element may also be arranged along a third direction. Optionally, the bracket 1 has a through hole along a third direction, and the first magnetic element 71 and the second magnetic element 72 are movably disposed in the through hole along the third direction.

[0166] Hinge assembly 100 from folded state ( Figure 3 (As shown) Move to the unfolded state ( Figure 2 During the process shown, the first magnetic element 71 and the second magnetic element 72 move away from each other; the hinge assembly 100 moves from the unfolded state (as shown). Figure 2 (As shown) Move to the folded state ( Figure 3 During the process shown, the first magnetic component 71 and the second magnetic component 72 approach each other.

[0167] In some embodiments, the hinge assembly 100 further includes a first locking member 51, a first elastic member 61, a second locking member 52, and a second elastic member 62.

[0168] The first locking member 51 is along the first direction (e.g.) Figure 1 The first locking member 51 is movably mounted on the first movable member 31 (shown in the vertical direction), and is rotatably connected to the bracket 1. The first locking member 51 has a first locking portion 511, the bracket 1 has a second locking portion 15, and a first elastic member 61 is disposed between the first locking member 51 and the first movable member 31. The first elastic member 61 applies a spring force to the first locking member 51 toward the second locking portion 15, so that the first locking portion 511 moves along a first direction (e.g., vertical direction). Figure 1 (As shown in the up and down direction) Stops the second locking part 15.

[0169] For example, the first locking member 51 can move vertically relative to the first movable member 31, and the first locking member 51 swings with the first movable member 31. The first elastic member 61 is a compression spring. The first locking part 511 is located above the second locking part 15, and the compression spring is located above the first locking part 511. The compression spring can apply a downward elastic force to the first locking part 511, so that the first locking part 511 stops against the second locking part 15, allowing the first movable member 31 to stop at more angles. This allows the terminal device with the hinge assembly 100 to stop at more unfolded angles, further improving the user experience.

[0170] Optionally, the first locking part 511 includes a first plane, a second plane, a first inclined surface, and a second inclined surface. The first plane, the first inclined surface, the second plane, and the second inclined surface are arranged sequentially around the rotation axis of the first movable member 31. The first plane is higher than the second plane. One end of the first inclined surface and the second inclined surface are connected to the first plane, and the other end of the first inclined surface and the second inclined surface are connected to the second plane. Correspondingly, the second locking part 15 includes a third plane, a fourth plane, a third inclined surface, and a fourth inclined surface. The third plane, the third inclined surface, the fourth plane, and the fourth inclined surface are arranged sequentially around the rotation axis of the first movable member 31. The third plane is lower than the fourth plane. One end of the third inclined surface and the fourth inclined surface are connected to the third plane, and the other end of the third inclined surface and the fourth inclined surface are connected to the fourth plane.

[0171] For example, the first plane is located above the second plane, and the third plane is located below the fourth plane. When the hinge assembly 100 is in the unfolded state, the rotation angle of the first movable member 31 is 0°, at which time the first plane is in contact with the third plane, and the second plane is in contact with the fourth plane. When the hinge assembly 100 rotates by a first angle (e.g., 10°), the first inclined surface is in contact with the third inclined surface, and under the elastic force of the first elastic member 61, the hinge assembly 100 tends to move towards the unfolded state. When the hinge assembly 100 rotates by a second angle (e.g., 60°), the first plane is in contact with the fourth plane, and at this time, the frictional force applied between the first and fourth planes by the first elastic member 61 is large. Under the elastic force of the first elastic member 61, the hinge assembly 100 can be suspended at any unfolded angle. When the hinge assembly 100 rotates by a third angle (e.g., 80°), the first inclined surface is in contact with the fourth inclined surface, and at this time, under the elastic force of the first elastic member 61, the hinge assembly 100 automatically moves towards the unfolded state.

[0172] The second locking element 52 is along the first direction (e.g.) Figure 1 The second locking member 52 is movably mounted on the second movable member 32 (shown in the vertical direction), and is rotatably connected to the bracket 1. The second locking member 52 has a third locking portion 521, the bracket 1 has a fourth locking portion 16, and a second elastic member 62 is disposed between the second locking member 52 and the second movable member 32. The second elastic member 62 applies a spring force to the second locking member 52 toward the fourth locking portion 16, so that the fourth locking portion 16 moves along a first direction (e.g., vertical direction). Figure 1 (As shown in the up and down direction) Stop at the third locking part 521.

[0173] For example, the second locking member 52 can move vertically relative to the second movable member 32, and the second elastic member 62 is a compression spring. The third locking part 521 is located below the fourth locking part 16, and the compression spring is located below the third locking part 521. The compression spring can apply an upward elastic force to the third locking part 521, thereby causing the third locking part 521 to stop against the fourth locking part 16, allowing the second movable member 32 to stop at more angles. This allows the terminal device with the hinge assembly 100 to stop at more unfolded angles, further improving the user experience.

[0174] It is understandable that the third locking part 521 can also adopt the structure of the first locking part 511 described above, that is, the third locking part 521 has multiple inclined surfaces and multiple planes, and the fourth locking part 16 can also adopt the structure of the second locking part 51 described above, that is, the fourth locking part 16 has multiple inclined surfaces and multiple planes. The hinge assembly 100 can be opened to multiple different angles through the cooperation of the third locking part 521 and the fourth locking part 16.

[0175] In some embodiments, the first support member 41 has a fifth mating portion 411, and the first movable member 31 has a sixth mating portion 314. The fifth mating portion 411 is rotatably mated with the sixth mating portion 314 along the swing axis of the first support member 41.

[0176] For example, such as Figure 1 As shown, the fifth mating part 411 and the sixth mating part 314 are rotatably mated along the swing axis of the first support member 41. Thus, through the mating of the fifth mating part 411 and the sixth mating part 314, the rotation between the first support member 41 and the first movable member 31 can be guided, which helps to improve the reliability of the hinge assembly 100.

[0177] In some embodiments, the second support member 42 has a seventh mating portion 421, and the second movable member 32 has an eighth mating portion 324. The seventh mating portion 421 is rotatably mated with the eighth mating portion 324 along the swing axis of the second support member 42.

[0178] For example, such as Figure 1 As shown, the seventh mating part 421 and the eighth mating part 324 are rotatably mated along the swing axis of the second support member 42. Thus, the mating of the seventh mating part 421 and the eighth mating part 324 guides the rotation between the second support member 42 and the second movable member 32, thereby improving the reliability of the hinge assembly 100.

[0179] In some embodiments, one of the fifth mating part 411 and the sixth mating part 314 is along the second direction (e.g., ...). Figure 1 The sixth arc-shaped protrusion extends in the left-right direction (as shown), and the other of the fifth mating part 411 and the sixth mating part 314 is along the second direction (as shown). Figure 1 The sixth arc-shaped groove extends in the left and right directions (as shown).

[0180] For example, both the sixth arc-shaped protrusion and the sixth arc-shaped groove extend in the left-right direction so that the fifth mating part 411 and the sixth mating part 314 can slide relative to each other in the left-right direction. The fifth mating part 411 is the sixth arc-shaped protrusion, and the sixth mating part 314 is the sixth arc-shaped groove; or the fifth mating part 411 is the sixth arc-shaped groove, and the sixth mating part 314 is the sixth arc-shaped protrusion. The sixth arc-shaped protrusion is movably disposed within the first arc-shaped groove in the left-right direction.

[0181] Thus, through the cooperation of the sixth arc-shaped protrusion and the sixth arc-shaped groove, the first support member 41 can rotate smoothly relative to the first movable member 31. Moreover, the structure of the sixth arc-shaped protrusion and the sixth arc-shaped groove is simple and easy to process and manufacture.

[0182] The fifth mating part 411 and the sixth mating part 314 may each be provided in one or more.

[0183] In some embodiments, one of the seventh mating part 421 and the eighth mating part 324 is along the second direction (e.g., ...). Figure 1 The seventh arc-shaped protrusion extends in the left-right direction (as shown), and the other of the seventh mating part 421 and the eighth mating part 324 is along the second direction (as shown). Figure 1 The seventh arc-shaped groove extends in the left and right directions (as shown).

[0184] For example, both the seventh arc-shaped protrusion and the seventh arc-shaped groove extend in the left-right direction so that the seventh mating part 421 and the eighth mating part 324 can slide relative to each other in the left-right direction. The seventh mating part 421 is the seventh arc-shaped protrusion, and the eighth mating part 324 is the seventh arc-shaped groove; or the seventh mating part 421 is the seventh arc-shaped groove, and the eighth mating part 324 is the seventh arc-shaped protrusion. The seventh arc-shaped protrusion is movably disposed within the seventh arc-shaped groove in the up-down direction.

[0185] Thus, through the cooperation of the seventh arc-shaped protrusion and the seventh arc-shaped groove, the second support member 42 can rotate smoothly relative to the second movable member 32. Moreover, the structure of the seventh arc-shaped protrusion and the ninth arc-shaped groove is simple and easy to process and manufacture.

[0186] The seventh mating part 421 and the eighth mating part 324 may each be provided with one or more.

The left end of the first part 316 is connected to the upper end of the second part 317. Thus, the second mating part 312 and the sixth mating part 314 are arranged in a direction perpendicular to the thickness direction of the hinge assembly 100, which is beneficial for the thin and light design of the terminal device.

[0189] In some embodiments, the second movable member 32 includes a third part 326 and a fourth part 327, the third part 326 and the fourth part 327 being arranged in an L-shape, a fourth mating part 322 being disposed on the third part 326, and an eighth mating part 324 being disposed on the fourth part 327.

[0190] For example, such as Figure 1 As shown, the third part 326 extends in the left-right direction, and the fourth part 327 extends in the up-down direction. The right end of the third part 326 is connected to the lower end of the fourth part 327. Thus, the fourth mating part 322 and the eighth mating part 324 are arranged in a direction perpendicular to the thickness direction of the hinge assembly 100, which is beneficial for the thinner and lighter design of the terminal device. Optionally, the bracket 1 has a first groove 17 and a second groove 18.

[0192] A portion of the first part 316 is disposed within the first groove 17, such that a portion of the first movable member 31 is located within the bracket 1; a portion of the third part 326 is disposed within the second groove 18, such that a portion of the second movable member 32 is located within the bracket 1. This facilitates further reduction in the thickness and weight of the hinge assembly 100, and promotes lightweight design of terminal devices incorporating the hinge assembly 100.

[0193] In some embodiments, the first locking member 51 has a seventh guide portion 512, and the first movable member 31 has an eighth guide portion 313, the eighth guide portion 313 being along a first direction (e.g., Figure 1 (As shown in the up-down direction) can be slidably engaged with the seventh guide part 512.

[0194] For example, such as Figure 1 As shown, the seventh guide portion 512 and the eighth guide portion 313 are connected and can slide relative to each other.

[0202] Therefore, when the fourth mating part 322 and the eighth mating part 324 rotate, they can drive the tenth guide part 323 to rotate, which in turn drives the second locking member 52 to rotate, so that the second locking member 52 and the second moving member 32 rotate synchronously, which makes it easier for the second locking member 52 to lock the second moving member 32, and helps to improve the reliability of the hinge assembly 100.

[0203] In some embodiments, the eighth guide portion 313 is provided on the second portion, and the sixth mating portion 314 and the eighth guide portion 313 are provided on opposite sides of the second portion 317.

[0204] For example, such as Figure 1 As shown, the eighth guide portion 313 is located on the right side of the second part 317, and the sixth mating portion 314 is located on the left side of the second part. Thus, the sixth mating portion 314 and the eighth guide portion 313 are arranged in a direction perpendicular to the thickness direction of the hinge assembly 100, which is beneficial to the thin and light design of the terminal device.

[0205] In some embodiments, the tenth guide portion 323 is provided on the fourth portion, and the eighth mating portion 324 and the tenth guide portion 323 are provided on opposite sides of the fourth portion.

[0212] Therefore, the third locking portion 521 and the ninth guide portion 522 are arranged in a direction perpendicular to the thickness direction of the hinge assembly 100, which is beneficial for the thinner and lighter design of the terminal device. In some embodiments, one of the seventh guide portion 512 and the eighth guide portion 313 is arranged in a first direction (e.g., ...). Figure 1 The eighth arc-shaped protrusion extends in the vertical direction (as shown), and the other of the seventh guide portion 512 and the eighth guide portion 313 is along the first direction (as shown).
