Description

Technical Field

[0001] This application relates to the field of electronic product technology, specifically to a hinge mechanism and a smart terminal. Background Technology

[0002] With the continuous development of electronic products, foldable screen devices are becoming increasingly popular. Foldable screen devices include flexible foldable screens and hinge mechanisms. The hinge mechanism includes a base, a swing arm, a slider, and a floating plate. The swing arm is rotatably connected to the base and slidably connected to the slider. The floating plate is rotatably connected to the slider, and the slider is used to connect to the mid-frame on the flexible foldable screen.

[0003] In conceiving and implementing this application, the inventors discovered at least the following problems: In some solutions, a guide groove is provided on the floating plate, and a guide post is provided on the swing arm. When the flexible folding screen is folded or unfolded, the relative sliding of the guide post and the guide groove limits the rotation angle of the floating plate relative to the slider, ensuring that the floating plate always abuts against the flexible folding screen. However, when limiting the rotation angle of the floating plate in the above manner, the guide post is located at one end of the guide groove in the folded state and at the other end in the unfolded state. This results in a long guide groove and a correspondingly large width required for the floating plate. Therefore, the hinge mechanism occupies a large space overall, affecting the layout of other components inside the folding screen device.

[0057] As shown in the background, the intelligent terminal includes a flexible folding screen and a hinge mechanism, the hinge mechanism includes a base, a swing arm, a sliding block and a floating plate, the swing arm is rotationally connected with the base and slidingly connected with the sliding block, the floating plate is rotationally connected with the sliding block, and the sliding block is used for being connected with a middle frame on the flexible folding screen. The floating plate abuts against the flexible folding screen, when the folding screen is folded, the floating plate rotates relative to the sliding block to push the flexible folding screen inward, so as to ensure that two parts of the flexible folding screen connected with the middle frame remain parallel in the folded state, and the appearance of the intelligent terminal in the folded state is improved.

[0058] In some schemes, a guide groove is formed on the floating plate, and a guide column is arranged on the swing arm, when the flexible folding screen is folded or unfolded, the rotation angle of the floating plate relative to the sliding block is limited through the relative sliding of the guide column and the guide groove, and it is ensured that the floating plate always abuts against the flexible folding screen.

[0059] However, when the rotation angle of the floating plate is limited by the above-mentioned manner, the guide column is located at one end of the guide groove in the folded state, and the guide column is located at the other end of the guide groove in the unfolded state, which leads to that the length of the guide groove is relatively long, and the width of the floating plate needs to be relatively large, so that the space occupied by the hinge mechanism as a whole is relatively large, and the layout of other elements inside the intelligent terminal is affected.

[0060] In view of the above technical problems, the embodiments of the present application provide a hinge mechanism and an intelligent terminal, the hinge mechanism includes a base, a synchronous rotation assembly and a floating plate, the intelligent terminal includes a support and a folding screen, the folding screen includes two symmetrical folding areas, the support is connected with the folding areas, the synchronous rotation assembly is rotationally connected with the base, and the synchronous rotation assembly is connected with the support, when the folding screen is unfolded or folded, the support and the synchronous rotation assembly rotate synchronously relative to the base.

[0061] Optionally, the floating plate is rotationally connected with at least part of the structure of the synchronous rotation assembly, when the synchronous rotation assembly rotates relative to the base, the floating plate rotates relative to the synchronous rotation assembly, so as to ensure that at least part of the structure of the floating plate abuts against the folding screen, when the folding screen is in the folded state, the floating plate pushes the folding screen inward, and the inclination angle of the part of the folding screen connected with the floating plate relative to the base is increased, so as to ensure that the two folding areas of the folding screen connected with the support remain parallel, and the appearance of the intelligent terminal is improved. Optionally, the floating plate has a first limiting structure and a second limiting structure, in the unfolded state, the second limiting structure is limitedly matched with the synchronous rotation assembly, so that the floating plate remains parallel with the folding screen, and the folding screen is supported, in the folded state, the first limiting structure is limitedly matched with the synchronous rotation assembly, so as to adjust the angle of the floating plate, and the floating plate pushes the folding screen inward.

[0062] In this way, the first limiting structure and the second limiting structure are arranged as two separate structures, two independent structures can be arranged on the synchronous rotating assembly to cooperate with the first limiting structure and the second limiting structure respectively, the first limiting structure and the second limiting structure can be arranged in a staggered manner, compared with the prior art in which only one guide groove for limiting is arranged, the sum of the lengths of the first limiting structure and the second limiting structure in the width direction of the floating plate is less than the length of the guide groove in the width direction of the floating plate, so that the width of the floating plate can be shortened, the space occupied by the hinge structure as a whole is reduced, more space inside the intelligent terminal is released, and the layout of other elements inside the intelligent terminal is facilitated.

[0063] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings:

[0064] Optionally, the hinge mechanism provided in the embodiments of the present application can be applied to various intelligent terminals.

[0065] The intelligent terminal provided in the embodiments of the present application comprises a hinge mechanism 100, a support and a folding screen. Optionally, the specific structure and working principle of the hinge mechanism 100 will be described in the specific embodiments below. The support is two, and the two supports are arranged on the two sides of the hinge mechanism 100 respectively and are connected with the two synchronous rotating assemblies 120 of the hinge mechanism 100 respectively. The folding screen comprises folding areas corresponding to the supports, and each folding area is connected with the corresponding support. When the folding screen is unfolded or folded, the folding areas rotate relative to the base 110 of the hinge mechanism 100, the folding areas drive the synchronous rotating assemblies 120 of the hinge mechanism 100 to rotate synchronously through the supports, and the two folding areas are arranged symmetrically relative to the hinge mechanism 100.

[0066] Referring to Figures 1 to 13As shown, the hinge mechanism 100 provided by the embodiment of the present application comprises a base 110, synchronous rotation assemblies 120 and a floating plate 130. The number of the synchronous rotation assemblies 120 can be two, and the two synchronous rotation assemblies 120 are respectively arranged on the two sides of the base 110. The two synchronous rotation assemblies 120 are connected with two supporting members of the intelligent terminal in correspondence. When the folding screen is unfolded or folded, the supporting members drive the synchronous rotation assemblies 120 to rotate relative to the base 110. The floating plate 130 is connected with the synchronous rotation assemblies 120. The floating plate 130 and at least part of the structure of the synchronous rotation assemblies 120 are rotatably connected, and the floating plate 130 is arranged on the side of the at least part of the structure close to the base 110. When the synchronous rotation assemblies 120 rotate relative to the base 110, the floating plate 130 rotates relative to the synchronous rotation assemblies 120, so as to ensure that at least part of the structure of the floating plate 130 abuts against the folding screen.

[0067] Optionally, Figure 1 In the embodiment, the X direction is the first direction, and the Y direction is the second direction. Figure 7 In the embodiment, the Z direction is the third direction. The floating plate 130 is provided with at least a first limiting structure 1321a and a second limiting structure 1322a. The first limiting structure 1321a and the second limiting structure 1322a are used to control the rotation angle of the floating plate 130 relative to the synchronous rotation assemblies 120. Optionally, the second limiting structure 1322a is used to limit the synchronous rotation assemblies 120 in the unfolded state, so that the floating plate 130 is parallel to the folding screen, thereby supporting the folding screen. The first limiting structure 1321a is used to limit the synchronous rotation assemblies 120 in the folded state, so that the floating plate 130 pushes the folding screen inward, thereby increasing the inclination angle of the part of the folding screen connected with the floating plate 130 relative to the base 110, so as to ensure that the two folding areas connected with the supporting members on the folding screen are parallel, thereby improving the appearance of the intelligent terminal. Optionally, under the action of the floating plate 130, the folding area and the part of the folding screen close to the base 110 are not in the same plane, and there is a certain included angle between them. Since the folding screen is a flexible display screen, the included angle does not affect the use of the folding screen and does not damage the folding screen.

[0068] Optionally, a guide slot is arranged on the floating plate 130, and a guide column is arranged on the synchronous rotating component 120; when the guide column is at one end of the guide slot, the floating plate 130 and the synchronous rotating component 120 are limited in the folding state; when the guide column is at the other end of the guide slot, the floating plate 130 and the synchronous rotating component 120 are limited in the unfolding state; that is, the guide slot is used to limit the two states, so the length of the guide slot should be greater than or equal to the relative sliding distance between the floating plate 130 and the synchronous rotating component 120, and the width of the floating plate 130 along the first direction should be greater than or equal to the length of the guide slot, so the width of the floating plate 130 is large, and the space occupied by the hinge mechanism 100 is large.

[0069] Optionally, in the embodiment of the present application, the first limiting structure 1321a and the second limiting structure 1322a are arranged on the floating plate 130, and two independent structures are arranged to limit the rotating angle of the floating plate 130 in the folding state and the unfolding state respectively; two independent cooperating structures can be arranged on the synchronous rotating component 120, and the two cooperating structures are spaced apart along the first direction; the first limiting structure 1321a and the second limiting structure 1322a can be staggered along the second direction, so that the first limiting structure 1321a and the second limiting structure 1322a partially overlap along the first direction; the distance between the end of the first limiting structure 1321a and the end of the second limiting structure 1322a along the first direction is equal to the relative sliding distance between the first limiting structure 1321a and the synchronous rotating component 120 minus the distance between the two cooperating structures. In the prior art, the length of the guide slot along the first direction is equal to the relative sliding distance between the floating plate 130 and the synchronous rotating component 120, so the distance between the end of the first limiting structure 1321a and the end of the second limiting structure 1322a along the first direction is less than the length of the guide slot along the first direction in the prior art, so the width of the floating plate 130 along the first direction can be reduced, which is beneficial to reducing the width of the hinge mechanism 100 along the first direction, and further releasing more space inside the intelligent terminal to reasonably optimize the layout of other elements inside the intelligent terminal. Optionally, the two cooperating structures can be two independent structures, or one structure with two limiting directions, and the embodiment of the present application does not limit this.

[0070] In some possible implementation manners, referring to Figures 1 to 6As shown, the floating plate 130 of the embodiment of the present application comprises a floating plate body 131 and a limiting baffle 132. Optionally, the floating plate body 131 is slidingly matched with the synchronous rotating assembly 120. The limiting baffle 132 extends along the sliding direction of the floating plate body 131. The limiting baffle 132 has a first end 1321 close to the base 110 and a second end 1322 away from the base 110. The first end 1321 is connected with the floating plate body 131, and the second end 1322 is spaced apart from the floating plate body 131. A first limiting structure 1321a is located at the first end 1321, and a second limiting structure 1322a is arranged at the second end 1322.

[0071] Optionally, the floating plate body 131 extends along the second direction. The floating plate body 131 and the synchronous rotating assembly 120 are rotationally connected along the part close to the base 110 in the first direction, and are slidingly matched along the part away from the base in the first direction. Thus, it can be ensured that the floating plate body 131 and the folding screen always keep in contact to support or push the folding screen during the rotation of the synchronous rotating assembly 120. The limiting baffle 132 is arranged on the floating plate body 131, and the relative position of the limiting baffle 132 and the floating plate body 131 remains unchanged. The first limiting structure 1321a is arranged at the first end 1321.

[0072] When in the unfolded state, the first limiting structure 1321a is limitedly matched with the synchronous rotating assembly 120 to drive the floating plate body 131 parallel to the folding screen, thereby supporting the folding screen and keeping the surface of the folding screen smooth and flat. The second limiting structure 1322a is arranged at the second end 1322. When in the folded state, the second limiting structure 1322a is limitedly matched with the synchronous rotating assembly 120 to make the second end 1322 inclined towards the base 110, thereby driving the floating plate body 131 as a whole to be inclined towards the base 110, so that the part of the folding screen close to the base 110 can be pushed inward from both sides, thereby keeping the two folding areas of the folding screen parallel and improving the appearance of the intelligent terminal.

[0073] Optionally, the first end 1321 is connected with the floating plate body 131, and the second end 1322 is spaced apart from the floating plate body 131, so that the first limiting structure 1321a and the second limiting structure 1322a are not in the same plane, thereby realizing the staggered arrangement of the first limiting structure 1321a and the second limiting structure 1322a, which is beneficial to shorten the width of the floating plate body 131 along the first direction and reduce the size of the hinge mechanism 100.

[0074] In some implementable manners, referring to Figures 1 to 6 As shown, the first limiting structure 1321a of the embodiment of the present application is located between the limiting baffle 132 and the floating plate body 131, and the second limiting structure 1322a is located on the side of the limiting baffle 132 away from the floating plate body 131.

[0075] Optionally, since the first limiting structure 1321a is used to limit the engagement with the synchronous rotation component 120 in the folded state, and the main function of the floating plate 130 is to push against the folded screen in the folded state, the first limiting structure 1321a needs to be set as a more stable structure to fix the floating plate body 131 at a certain angle and enable the floating plate body 131 to apply a certain pushing force to the folded screen. Therefore, the first limiting structure 1321a is set between the limiting baffle 132 and the floating plate body 131 to ensure the stability of the first limiting structure 1321a. The second limiting structure 1322a is used to limit the engagement with the synchronous rotation component 120 in the unfolded state. At this time, the floating plate 130 only plays a certain supporting role and does not need to apply additional pressure to the folded screen. Therefore, in order to make the second limiting structure 1322a staggered from the first limiting structure 1321a, the second limiting structure 1322a can be set on the side of the limiting baffle 132 facing away from the floating plate body 131.

[0076] See also some of the possible implementation methods. Figure 1 and Figures 4 to 12 As shown, the limiting baffle 132 of this application embodiment includes: a first limiting groove and a second limiting groove. Optionally, the first limiting structure 1321a is formed as a first limiting groove located between the limiting baffle 132 and the float body 131, with the first limiting groove having an opening at one end facing away from the base 110. The second limiting structure 1322a is formed as a second limiting groove, with the second limiting groove having an opening at one end facing the base 110.

[0077] Optionally, the first limiting structure 1321a is a first limiting groove. When the hinge mechanism 100 changes from an unfolded state to a folded state, the first end 1321 of the limiting baffle 132 tends to slide away from the base 110 relative to the synchronous rotation assembly 120. Optionally, the opening of the first limiting groove faces away from the base 110 to ensure that when the hinge mechanism 100 is in the folded state, the bottom of the first limiting groove abuts against the mating structure on the synchronous rotation assembly 120 to achieve a limiting fit. The second limiting structure 1322a is formed as a second limiting groove. When the hinge mechanism 100 changes from a folded state to an unfolded state, the second end 1322 of the limiting baffle 132 tends to slide closer to the base 110 relative to the synchronous rotation assembly 120. Therefore, the opening of the second limiting groove faces the base 110 to ensure that when the hinge mechanism 100 is in the unfolded state, the bottom of the second limiting groove abuts against the mating structure on the synchronous rotation assembly 120 to achieve a limiting fit.

[0078] Optionally, the first limiting groove and the second limiting groove can be respectively provided on opposite sides of the limiting baffle 132 along the second direction, such as... Figure 14 and Figure 15 As shown, Figure 14 and Figure 15respectively, are structural schematic views of the first limiting groove and the second limiting groove observed from two opposite sides of the limiting baffle 132 along the second direction, so that the first limiting groove and the second limiting groove are staggered, which is beneficial to further saving the width of the floating plate 130 along the first direction.

[0079] In some implementable manners, referring to Figure 1 and Figures 4 to 15 shown, the second limiting groove of the embodiment of the present application has a first groove wall 1322a1 and a second groove wall 1322a2; the first groove wall 1322a1 is located at one side of the second limiting groove facing the floating plate body 131, and the second groove wall 1322a2 is located at one side of the second limiting groove away from the floating plate body 131, and the projection of the second groove wall 1322a2 on the floating plate body is shorter than the projection of the first groove wall 1322a1 on the floating plate body 131.

[0080] Optionally, since the second limiting groove is located at one side of the limiting baffle 132 away from the floating plate body 131, in order to avoid interference with the connection between the floating plate 130 and the folding screen, the length of the second groove wall 1322a2 can be set to be shorter than the length of the first groove wall 1322a1, that is, the length of the limiting baffle 132, so that the flatness of the surface of the floating plate 130 can be maintained as much as possible without affecting the limiting effect of the second limiting groove, so as to ensure the stability of the connection between the floating plate 130 and the folding screen.

[0081] Optionally, the two groove walls of the first limiting groove are respectively formed by the part of the floating plate body 131 and the limiting baffle 132, and the first limiting groove is separated from the folding screen by the second limiting groove, so that the lengths of the two groove walls of the first limiting groove can be set to be equal, which can play a certain guiding role while forming a limiting cooperation with the cooperating structure, so as to avoid the cooperating structure from sliding out of the first limiting groove.

[0082] In some implementable manners, referring to Figures 1 to 13 shown, the synchronous rotating assembly 120 of the embodiment of the present application includes a swing arm 121, the swing arm 121 is rotatably connected with the base 110, the swing arm 121 includes a first cooperating structure 1212 and a second cooperating structure 1213, the first cooperating structure 1212 is in limiting cooperation with the first limiting structure 1321a; and the second cooperating structure 1213 is in limiting cooperation with the second limiting structure 1322a.

[0083] Optionally, when the hinge mechanism 100 is converted from the unfolded state to the folded state, the first matching structure 1212 enters the first limiting groove and slides along the groove wall of the first limiting groove to the bottom of the first limiting groove, thereby realizing the angle limitation of the floating plate 130 in the folding process; when the hinge mechanism 100 is converted from the folded state to the unfolded state, the second matching structure 1213 enters the second limiting groove and slides along the groove wall of the second limiting groove to the bottom of the second limiting groove, thereby realizing the angle limitation of the floating plate 130 in the unfolding process.

[0085] In some realizable modes, as shown in Figure 1 , Figure 5 , Figure 7 , Figure 8 and Figure 13 , the distance between the first matching structure 1212 and the base 110 is greater than the distance between the second matching structure 1213 and the base 110.

[0086] In this way, the first matching structure 1212 and the second matching structure 1213 have a certain interval in the first direction, and the groove bottoms of the first limiting groove and the second limiting groove corresponding to the first matching structure 1212 and the second matching structure 1213 also have a certain interval in the first direction, so that the projection of the first limiting groove and the second limiting groove in the second direction partially overlaps, thereby shortening the total length of the first limiting groove and the second limiting groove in the first direction, which is beneficial to shorten the length of the limiting baffle 132, thereby reducing the width of the floating plate body 131, and releasing more space inside the folding screen.

[0087] In some realizable modes, as shown in Figure 1 , Figure 5 , Figure 7 , Figure 8 and Figure 13 , the distance between the first matching structure 1212 and the base 110 is greater than the distance between the second matching structure 1213 and the base 110.As shown, the swing arm 121 of the embodiment of the present application further comprises a swing arm body, the swing arm body is in sliding fit with the floating plate body 131, the swing arm body is provided with an avoiding groove 1211 matched with the limiting baffle 132, the avoiding groove 1211 has a third groove wall 1211a and a fourth groove wall 1211b opposite along the axial direction of the base 110, one of the first matching structure 1212 and the second matching structure 1213 is arranged on the third groove wall 1211a, and the other is arranged on the fourth groove wall 1211b.

[0088] Optionally, the width of the avoiding groove 1211 along the second direction should be greater than the width of the limiting baffle 132, the two groove walls opposite along the second direction of the avoiding groove 1211 are the third groove wall 1211a and the fourth groove wall 1211b, the first matching structure 1212 and the second matching structure 1213 are arranged on the third groove wall 1211a and the fourth groove wall 1211b respectively, and the positions of the first limiting groove and the second limiting groove correspond to the first matching structure 1212 and the second matching structure 1213, the first matching structure 1212 and the second matching structure 1213 arranged on the two groove walls can avoid the interference between the first matching structure 1212 and the second limiting groove or the second matching structure 1213 and the first limiting groove when the swing arm 121 rotates, thereby affecting the sliding between the swing arm body and the floating plate body 131.

When the width of the floating plate 130 is reduced, the distance between the rotating shaft slider 122 and the base 110 is also shortened accordingly, thereby further reducing the width of the hinge mechanism 100 along the first direction.
