Description

Technical Field

[0001] This application relates to the field of hinge structure technology, and in particular to a hinge structure, a foldable screen module, and electronic products. Background Technology

[0002] Compared to traditional electronic product designs, multi-screen electronic products have more screens for information interaction. However, electronic products are currently trending towards thinner and lighter designs. Therefore, when increasing the number of screens, it is necessary to avoid increasing or excessively increasing the size of the electronic product.

[0003] When using multi-screen electronic products, multiple screens are unfolded to obtain a larger display screen. When not in use, some screens are stored by folding or shrinking.

[0004] In existing foldable laptops, the extended screen is located below the original display. When not in use, the extended screen is stored at the bottom of the system. When in use, the extended screen slides out from the bottom of the system and forms a larger screen with the original display.

[0005] The foldable screen is connected to a sliding base via a hinge. The base and the foldable screen slide synchronously. If a traditional hinge structure is used, the foldable screen and the base can rotate relative to each other when the foldable screen is not in use. This creates a gap between the two when the foldable screen is at the bottom of the system, which affects the normal use of the laptop. Summary of the Invention

[0006] To address at least the above-mentioned technical problems existing in the prior art, this application provides a hinge structure, a foldable screen module, and an electronic product.

[0008] In some embodiments, the hinge assembly includes a hinge body, a first connecting piece, and a second connecting piece. The first connecting piece is fixedly connected to the hinge body, and the second connecting piece is rotatably connected to the hinge body. The first connecting piece is connected to the foldable screen, and the hinge body is connected to the connecting end, while the second connecting piece is connected to the base.

[0009] In some embodiments, the connecting end includes a limiting protrusion, the locking end includes a limiting groove, the limiting protrusion is connected to the rotating shaft body, and the triggering component is used to drive the limiting groove to lock or unlock with the limiting protrusion; when the limiting groove is locked with the limiting protrusion, the limiting protrusion and the limiting groove are inserted into each other, and the limiting groove limits the rotation of the limiting protrusion; when the limiting groove is unlocked from the limiting protrusion, the limiting protrusion and the limiting groove are separated.

[0010] In some embodiments, the first connecting piece is disposed at one end of the rotating shaft body, and the limiting protrusion is disposed at the end of the rotating shaft body away from the first connecting piece; the triggering component is located on one side of the rotating shaft body and is used to drive the limiting groove to extend and retract along the axial direction of the rotating shaft body.

[0011] In some embodiments, the locking end further includes a rotating sleeve, the opening of which is disposed facing the limiting protrusion, and the limiting groove is disposed at the end of the rotating sleeve away from the opening; the connecting end further includes a rotating column, one end of which is fixedly connected to the rotating shaft body, and the other end of which is disposed of the limiting protrusion; when the limiting groove and the limiting protrusion are unlocked, the rotating column rotates within the rotating sleeve.

[0012] In some embodiments, the opening end of the rotating sleeve is provided with a snap-fit ​​protrusion, and the end of the rotating shaft body is provided with a snap-fit ​​groove; when the limiting groove is locked with the limiting protrusion, the snap-fit ​​protrusion snaps into the snap-fit ​​groove.

[0013] In some embodiments, the triggering component includes a bracket, a telescopic shaft, and a triggering end; the bracket is connected to the second connecting piece or the base, the bracket has a through hole, the telescopic shaft passes through the through hole, one end of the telescopic shaft is connected to the locking end, and the other end is connected to the triggering end; the triggering end is used to drive the telescopic shaft to move axially, so that the locking end locks or unlocks the connecting end.

[0014] In some embodiments, the triggering component further includes an elastic element and a guide element. The elastic element is sleeved on the telescopic shaft, and the guide element is disposed on the travel distance of the triggering end. When the folding screen moves, the pivot structure and the base move synchronously. The guide element is used to drive the triggering end to move axially along the telescopic shaft. When the guide element drives the triggering end to move, the telescopic shaft overcomes the rebound force of the elastic element, causing the locking end to unlock from the connecting end. When the drive of the guide element on the triggering end disappears, the elastic element drives the telescopic shaft to reset, causing the locking end to lock with the connecting end.

[0015] This application also provides a foldable screen module, including the aforementioned hinge structure.

Conversely, when the foldable screen needs to be used, it needs to be rotated at a certain angle. A trigger component unlocks the locking end and the connecting end, thus satisfying the rotation requirements of the foldable screen. In this technical solution, the locking component, in conjunction with the trigger component, can lock or unlock the connecting end, ensuring stability during use. Furthermore, the locking state can be switched synchronously when the foldable screen's state changes. The triggering operation of the locking component is simple and quick, improving efficiency.

[0032] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] This application provides a hinge structure for connecting a base and a foldable screen, including a hinge assembly, a locking assembly, and a triggering assembly. The hinge assembly connects the base and the foldable screen. When rotated, the hinge assembly performs an angular rotation action and provides torque. The locking assembly and the triggering assembly cooperate to lock or unlock the hinge assembly.

[0034] The following description, in conjunction with the accompanying drawings, details the components of the rotating shaft structure provided in the embodiments of this application, the positional relationships between the components, and the connection relationships.

[0035] In this embodiment, the hinge structure is applied between the base and the folding screen. The electronic product includes a display screen and an extended screen. Under normal application conditions, only the display screen is used and the extended screen is not used. However, when a larger display interface is required, the extended screen needs to be pulled out and flipped at a certain angle for use.

[0036] Multiple pivot structures can be set between the connection end of the base and the connector. The pivot structure allows the extended screen to rotate. At the same time, it can switch between locked and unlocked states. In the locked state, the base and the connector are relatively fixed and there will be no relative angular change.

[0037] like Figures 1 to 3As shown, the locking assembly 40 includes a connecting end 41 and a locking end 42. The connecting end 41 is connected to the rotating shaft assembly 30, and the locking end 42 is connected to the triggering assembly 50. The connecting end 41 can be connected to or separated from the locking end 42. When the two are connected, the rotating shaft assembly 30 is locked and cannot rotate. When the two are separated, the rotating shaft assembly 30 is unlocked and can rotate. The connection or separation of the locking end 42 and the connecting end 41 is triggered by the triggering assembly 50. Specifically:

[0038] In this embodiment of the application, the pivot assembly 30 includes a pivot body 31, a first connecting piece 32 and a second connecting piece 33. The first connecting piece 32 is fixedly connected to the pivot body 31, and the second connecting piece 33 is rotatably connected to the pivot body 31. The first connecting piece 32 is connected to the folding screen 20, and the pivot body 31 is connected to the connecting end 41, and the second connecting piece 33 is connected to the base 10.

[0039] In the unlocked state, the shaft body 31 can rotate under the action of the first connecting piece 32 and / or the second connecting piece 33. In this embodiment, a connecting end 41 is provided on the shaft body 31. By locking or unlocking the connecting end 41, the rotation of the shaft body 31 can be controlled.

[0040] For example, the connecting end 41 is located at one end of the rotating shaft body 31 and extends along the axial direction of the rotating shaft body 31. For example, the connecting end 41 includes a limiting protrusion 43, and the locking end 42 includes a limiting groove 44. The limiting protrusion 43 is connected to the rotating shaft body 31, and the trigger component 50 is used to drive the limiting groove 44 to lock or unlock the limiting protrusion 43. When the limiting groove 44 and the limiting protrusion 43 are locked, the limiting protrusion 43 and the limiting groove 44 are inserted into each other, and the limiting groove 44 limits the rotation of the limiting protrusion 43. When the limiting groove 44 and the limiting protrusion 43 are unlocked, the limiting protrusion 43 and the limiting groove 44 are separated.

[0041] For example, the first connecting piece 32 is located at one end of the rotating shaft body 31, and the limiting protrusion 43 is located at the end of the rotating shaft body 31 away from the first connecting piece 32; the trigger component 50 is located on one side of the rotating shaft body 31 and is used to drive the limiting groove 44 to extend and retract along the axial direction of the rotating shaft body 31, wherein the moving distance of the limiting groove 44 satisfies the insertion or separation with the limiting protrusion 43, and the axial driving method of the trigger component 50 is described below.

[0042] For example, the limiting protrusion 43 is a non-cylindrical protrusion structure, and the limiting groove 44 is adapted to the shape of the limiting protrusion 43. That is, when the limiting protrusion 43 is inserted into the limiting groove 44, the limiting protrusion 43 cannot rotate within the limiting groove 44, thus avoiding ineffective limiting. For example, the limiting protrusion 43 is a rectangular protrusion structure, and the corresponding limiting groove 44 includes a rectangular groove.

[0043] Continue to refer to Figures 4 to 5 As shown in the embodiment of this application, the locking end 42 further includes a rotating sleeve 45, the opening of the rotating sleeve 45 is disposed facing the limiting protrusion 43, and a limiting groove 44 is disposed at the end of the rotating sleeve 45 away from the opening; the connecting end 41 further includes a rotating column 46, one end of the rotating column 46 is fixedly connected to the rotating shaft body 31, and the other end is disposed of the limiting protrusion 43; when the limiting groove 44 and the limiting protrusion 43 are unlocked, the rotating column 46 rotates inside the rotating sleeve 45.

[0044] The rotating sleeve 45 has a certain depth. When the limiting protrusion 43 and the limiting groove 44 separate, the rotating column 46 is not completely pulled out of the rotating sleeve 45. The interface shape of the rotating sleeve 45 and the rotating column 46 is circular. When the rotating shaft body 31 rotates, the rotating column 46 rotates inside the rotating shaft sleeve. By setting the structure of the rotating sleeve 45 and the rotating column 46, the two can cooperate to rotate and further limit the movement, and prevent the limiting protrusion 43 from being exposed, thus providing protection.

[0045] For example, in this embodiment of the application, the opening end of the rotating sleeve 45 is provided with a snap-fit ​​protrusion 47, and the end of the rotating shaft body 31 is provided with a snap-fit ​​groove 48; when the limiting groove 44 and the limiting protrusion 43 are locked, the snap-fit ​​protrusion 47 and the snap-fit ​​groove 48 snap together.

[0046] For example, multiple snap-fit ​​protrusions 47 are spaced circumferentially at the open end of the rotating sleeve 45, and multiple snap-fit ​​grooves 48 are provided circumferentially at the end of the rotating shaft body 31. The number of snap-fit ​​protrusions 47 and snap-fit ​​grooves 48 is the same. In the locked state, the snap-fit ​​protrusions 47 are inserted into the snap-fit ​​grooves 48, which further plays a limiting role. By cooperating with the snap-fit ​​protrusions 47 and snap-fit ​​grooves 48, the force when the rotating shaft body 31 rotates is not concentrated between the limiting protrusions 43 and the limiting grooves 44. The force is distributed and the stability in the locked state can be ensured.

[0047] In this embodiment, the triggering component 50 includes a bracket 51, a telescopic shaft 52, and a triggering end 53. The bracket 51 is connected to the second connecting piece 33 or the base 10. The bracket 51 is provided with a through hole 54. The telescopic shaft 52 passes through the through hole 54. One end of the telescopic shaft 52 is connected to the locking end 42, and the other end is connected to the triggering end 53. The triggering end 53 is used to drive the telescopic shaft 52 to move axially so that the locking end 42 locks or unlocks the connecting end 41.

[0048] By adjusting the trigger end 53 to adjust the axial movement of the telescopic shaft 52, the locking end 42 can move closer to or further away from the connecting end 41. In this embodiment, when the folding screen 20 is in use, it is necessary to move the distance between the folding screen 20 and the base 10 horizontally. Therefore, the telescopic shaft 52 can be driven during the movement.

[0049] For example, the trigger assembly 50 also includes an elastic element 55 and a guide element 56. The elastic element 55 is sleeved on the telescopic shaft 52, and the guide element 56 is located on the travel of the trigger end 53. For example, the elastic element 55 is a spring. In the locked state, under the action of the spring, the locking end 42 and the connecting end 41 remain locked. When the folding screen 20 moves, the pivot structure and the base 10 move synchronously. The guide element 56 is used to drive the trigger end 53 to drive the telescopic shaft 52 to move axially. For example, the guide element 56 is a slide rail arranged along the moving direction. The slide rail has a set width. The guide element 56 moves within the slide rail. As the guide element 56 moves, the width of the slide rail decreases. There is an inclined guide surface 57 between the wide part and the relatively narrow part of the slide rail.

[0050] When the guide member 56 moves in contact with the guide surface 57, the telescopic shaft 52 overcomes the rebound force of the elastic member 55, causing the locking end 42 to be unlocked from the connecting end 41. In the contact-locked state, the rotating shaft assembly 30 can rotate.

[0051] When it is necessary to reset the folding screen 20 and the base 10, the folding screen 20 is rotated to reset. Then, the folding screen 20 and the base 10 are moved in the opposite direction. The guide 56 moves from the relatively narrow part of the slide rail to the wide part. At this time, when the drive of the guide 56 to the trigger end 53 disappears, the elastic element 55 drives the telescopic shaft 52 to reset, so that the locking end 42 is locked with the connecting end 41.

[0052] This application provides a foldable screen module, including the aforementioned hinge structure. The foldable screen module includes a display body and a foldable screen 20, which are connected to the display body via the hinge structure.

[0053] When the foldable screen 20 is not in use, it is locked to the base 10 and will not rotate relative to each other, ensuring the stability of the foldable screen module during use.

[0054] This application provides an electronic product that includes the aforementioned hinge structure or the aforementioned foldable screen module. Taking a laptop computer as an example, the laptop's display 60 and foldable screen 20 are connected by a U-shaped hinge, and the foldable screen 20 and base 10 are connected by the hinge structure.

[0055] like Figure 6As shown, when the laptop is not in use or when only the screen of the display end 60 is used, the hinge structure is in a locked state, so that the base 10 and the folding screen 20 remain in a horizontal state and are in contact with the bottom of the system end 70.

[0056] like Figure 7 As shown, when the foldable screen 20 of the laptop is in use, the foldable screen 20 and the base 10 slide horizontally at the bottom of the system terminal 70. The hinge structure slides to the edge of the system terminal 70, at which point the hinge structure is unlocked. The foldable screen 20 is rotated through the hinge structure, forming a larger display structure with the display screen of the system terminal 70. When the foldable screen 20 is not in use, the operation is reversed. First, the foldable screen 20 is rotated to a horizontal position, and then it slides synchronously with the base 10 to the bottom of the system terminal 70, while the base 10 and the foldable screen 20 remain locked.

[0057] This application provides a hinge structure, a foldable screen module, and an electronic product. When the foldable screen 20 is not in use, the locking end 42 and the connecting end 41 are locked, thus restricting the rotation of the hinge assembly 30 and preventing gaps between the folding end and the bottom of the system end 70. Conversely, when the foldable screen 20 needs to be used, it needs to be rotated at a certain angle. The locking end 42 and the connecting end 41 are unlocked by the trigger component 50, thereby satisfying the rotation requirements of the foldable screen 20. In this technical solution, the locking component, in conjunction with the trigger component 50, can lock or unlock the connecting end 41, ensuring stability during use. Furthermore, the locking state can be switched synchronously when the state of the foldable screen 20 changes. The triggering operation of the locking component 40 is simple and quick, improving efficiency.
