Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] In related technologies, the design of electronic devices that allow for screen storage is mostly a foldable screen design. However, when the screen is folded, a small folding angle is formed, which causes greater stress at the bending point, which can damage the screen's lifespan and affect the user experience. Summary of the Invention

[0003] This application aims to provide an electronic device that can solve or improve the technical problem in the related art where the lifespan of the screen is affected by the screen folding design in retractable electronic devices.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, this application provides an electronic device, comprising:

[0006] case;

[0007] A hinge assembly is mounted on the housing, and the hinge assembly has a coiled state and a straight state;

[0008] A flexible screen assembly is located on the hinge assembly, and the flexible screen assembly moves with the hinge assembly;

[0009] The drive component is connected to the hinge component. The drive component has a first state and a second state. When the drive component is in the first state, the hinge component is in a coiled state. When the drive component is in the second state, the hinge component is in a straight state.

[0010] In the embodiments of this application, the electronic device includes a housing, a hinge assembly, a flexible screen assembly, and a driving assembly. The hinge assembly is disposed on the housing, the flexible screen assembly is disposed on the top cover of the hinge assembly, and the driving assembly is connected to the hinge assembly. It can drive the hinge assembly to be wound into a wound state or unfolded into a flat state. Furthermore, the flexible screen assembly can move synchronously with the movement of the hinge assembly to roll up and unfold, thereby changing the state of the flexible screen assembly to adapt to different scenario requirements.

[0011] Specifically, the driving component also has two states, namely a first state and a second state. When the driving component is in the first state, it pulls the hinge component, causing the hinge component to roll up to achieve a rolled-up state, and the flexible screen component rolls up along with the hinge component.

[0012] When the drive component is in the second state, the hinge component is pulled to unfold the hinge component to achieve a flat state, and the flexible screen component unfolds along with the unfolding of the hinge component.

[0013] As shown above, by switching the state of the driving component, the hinge component can switch between the unfolded state and the rolled state. Moreover, the rolling of the hinge component produces a larger bending angle compared to the bending form. Therefore, when the hinge component is in the rolled state, the possibility of creases on the flexible screen component can be reduced, thus improving the screen's lifespan.

[0027] The following is combined Figures 1 to 5 This application describes an electronic device 100 according to an embodiment of the present application.

[0028] like Figure 1 and Figure 2As shown, in its first aspect, this application provides an electronic device 100, comprising: a housing 110; a hinge assembly 120 disposed on the housing 110, the hinge assembly 120 having a wound state and a straight state; a flexible screen assembly 130 disposed on the hinge assembly 120, the flexible screen assembly 130 moving with the hinge assembly 120; and a drive assembly 140 connected to the hinge assembly 120, the drive assembly 140 having a first state and a second state. When the drive assembly 140 is in the first state, the hinge assembly 120 is in the wound state, and when the drive assembly 140 is in the second state, the hinge assembly 120 is in the straight state.

[0029] In the embodiments of this application, the electronic device 100 includes a housing 110, a hinge assembly 120, a flexible screen assembly 130, and a drive assembly 140. The hinge assembly 120 is disposed on the housing 110, the flexible screen assembly 130 is disposed on the top cover of the hinge assembly 120, and the drive assembly 140 is connected to the hinge assembly 120. The drive assembly 140 can drive the hinge assembly 120 to be wound into a wound state or unfolded into a flat state. Furthermore, the flexible screen assembly 130 can move synchronously with the movement of the hinge assembly 120 to roll up and unfold, thereby changing the state of the flexible screen assembly 130 to adapt to different scenario requirements.

[0030] Specifically, the drive component 140 also has two states, namely the first state and the second state.

[0031] like Figure 1 As shown, when the drive component 140 is in the first state, it pulls the hinge component 120, causing the hinge component 120 to roll up to achieve a rolled-up state. The flexible screen component 130 rolls up along with the hinge component 120.

[0032] like Figure 2 As shown, when the drive component 140 is in the second state, the hinge component 120 is pulled to unfold the hinge component 120 to achieve a flat state, and the flexible screen component 130 unfolds along with the unfolding of the hinge component 120.

[0033] Furthermore, the flexible screen component 130 can adopt a modular design, allowing for the replacement of the main screen with more layers and a larger aspect ratio according to usage requirements.

[0034] As described above, by switching the state of the drive component 140, the hinge component 120 is switched between the unfolded state and the rolled state. Furthermore, the rolling of the hinge component 120 produces a larger bending angle compared to the bending form. Therefore, when the hinge component 120 is in the rolled state, the possibility of creases on the flexible screen component 130 can be reduced, thereby improving the lifespan of the screen.

[0035] Among them, the flexible screen component 130 can be a rollable screen.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in one possible implementation, the drive assembly 140 includes: a traction member 142 connected to the hinge assembly 120; and a drive member 144 drivenly connected to the traction member 142, wherein the drive member 144 can drive the traction member 142 to pull the hinge assembly 120, causing the hinge assembly 120 to enter a wound state or a straight state. The drive member 144 is disposed on the housing 110.

[0037] Specifically, the drive assembly 140 includes a traction member 142 and a drive member 144. The drive member 144 and the traction member 142 are drivably connected. The drive member 144 pulls the hinge assembly 120 to move via the traction member 142, causing the hinge assembly 120 to switch states. That is, by adjusting the relative length of the traction member 142, the drive member 144 can switch the hinge assembly 120 between a straight state and a wound state. The traction member 142 can be a nylon belt, steel wire belt, rubber belt, resin belt, or plastic belt, etc.

[0038] like Figure 1 As shown, the driving component 144 drives the traction component 142 to pull the hinge assembly 120, thereby causing the hinge assembly 120 to be wound up, that is, the driving component 140 enters the first state, so that the hinge assembly 120 is in the wound state.

[0039] like Figure 2 As shown, the driving component 144 drives the traction component 142 to pull the hinge assembly 120, thereby causing the hinge assembly 120 to unfold, that is, the driving component 140 enters the second state, so that the hinge assembly 120 is in a straight state.

[0040] Furthermore, by driving the traction member 142 through the driving member 144, the hinge assembly 120 carrying the flexible screen assembly 130 can switch between the unfolded state and the rolled-up state.

[0041] like Figure 1 and Figure 2 As shown, in one possible implementation, the hinge assembly 120 includes: a plurality of hinge bodies 122; a pivot 124, wherein adjacent hinge bodies 122 are connected by the pivot 124; wherein the plurality of hinge bodies 122 can be wound or stretched by the drive assembly 140.

[0042] Specifically, the hinge assembly 120 includes a plurality of hinge bodies 122, adjacent hinge bodies 122 are connected by a pivot 124, and the plurality of hinge bodies 122 form a chain-like hinge assembly 120 through the pivot 124. Furthermore, the pivot 124 allows the plurality of hinge bodies 122 to be rolled up and unfolded, and the flexible screen assembly 130 can be attached to the plurality of hinge bodies 122.

[0043] Furthermore, such as Figure 4 As shown, in order to reduce weight and cost, the shaft 124 can adopt a hollow structure, that is, a cavity 126 is formed in the middle of the shaft 124, so as to reduce the amount of material used and reduce weight.

[0044] Specifically, the hinge body 122 can be made of carbon fiber, metal or plastic, etc., and the pivot 124 can be made of carbon fiber, metal or plastic, etc.

[0045] like Figure 4 As shown, in one possible implementation, there are multiple hinge assemblies 120, which are arranged at intervals, and the pivot 124 in the multiple hinge assemblies 120 is an integral structure. There are multiple drive assemblies 140, which are arranged correspondingly to the hinge assemblies 120.

[0046] Specifically, there are multiple hinge components 120, which are arranged at intervals. The flexible screen component 130 is disposed on the multiple hinge components 120. Since the flexible screen component 130 moves with the hinge components 120, the multiple hinge components 120 can increase the driving force of the hinge components 120 on the flexible screen component 130, thereby improving the stability of the movement of the flexible screen component 130.

[0047] Furthermore, the pivot 124 in the multiple hinge assemblies 120 is an integral structure, thereby ensuring that the multiple hinge assemblies 120 can move synchronously and improving the uniformity of the movement of the hinge assemblies 120.

[0048] There are also multiple drive components 140, with one drive component 140 driving the movement of one hinge component 120, thus increasing the driving force.

[0049] like Figure 4 As shown, there can be two hinge assemblies 120. The pivot 124 in the two hinge assemblies 120 is an integral structure. The flexible screen assembly 130 can be attached to the pivot 124 and sandwiched between the hinge bodies 122 of the two hinge assemblies 120.

[0050] like Figure 1 and Figure 2As shown, in one possible implementation, both ends of the traction member 142 are connected to the hinge body 122 or the rotating shaft 124 located at one end of the hinge assembly 120. The two ends of the traction member 142 are respectively located on both sides of the rotating shaft 124, and the traction member 142 bypasses the hinge body 122 located at the other end of the hinge assembly 120. The driving member 144 can drive the traction member 142 to move to both an equal-length state and an unequal-length state. When the traction member 142 is in the unequal-length state, the hinge assembly 120 is in a wound state; when the traction member 142 is in the equal-length state, the hinge assembly 120 is in a straight state. A wear-resistant coating may be provided on the hinge body 122 and / or the rotating shaft 124.

[0051] Specifically, the two ends of the traction member 142 are connected to the hinge body 122 located at one end of the hinge assembly 120. The two ends of the traction member 142 are located on both sides of the pivot 124, and the traction member 142 passes around the hinge body 122 at the other end of the hinge assembly 120. That is, the traction member 142 is approximately "U" shaped and passes around the hinge assembly 120.

[0052] like Figure 1 As shown, when the traction member 142 is in a state of unequal length on both sides and the support component is in a flexible state, the traction member 142 pulls the hinge assembly 120 to the side with the shorter length of the traction member 142 to wind it, thereby making the hinge assembly 120 in a wound state.

[0053] like Figure 2 As shown, with the traction member 142 in an equal-length state on both sides, the hinge assembly 120 can unfold into a flat state, allowing the support component to be in a supporting state and support the hinge assembly 120, thus allowing the hinge assembly 120 to switch between a coiled state and a straight state. The traction member 142 enables the hinge assembly 120 to switch back and forth between a coiled state and a straight state, thereby increasing the bending angle, eliminating creases, and improving the user experience.

[0054] Specifically, such as Figure 3 As shown, the driving component 144 includes a motor 152 and a winch 154, which are connected. The winch 154 is located on one side of the hinge assembly 120. The traction component 142 bypasses the winch 154 and connects to the hinge body 122 at the other end of the hinge assembly 120, thus realizing the driving component 144 driving the traction component 142. The output shaft of the motor 152 rotates, driving the winch 154 to rotate, thereby driving the change in length of both sides of the traction component 142. When the length of one side of the traction component 142 increases, the length of the other side of the traction component 142 will decrease. That is, the operation of the driving component 144 allows a length difference to appear on both sides of the traction component 142. Specifically, as... Figure 3As shown by the middle arrow, when the motor 152 drives the winch 154 to rotate to the left, the traction member 142 will also move to the left, and the left side of the traction member 142 will lengthen while the right side will shorten, thus entering an unequal length state.

[0055] Driven by the drive member 144, the traction member 142 is transferred from one side to the other by friction, thereby realizing the adjustment of the traction member 142 in the state of equal length on both sides and the state of unequal length on both sides.

[0056] The traction member 142 can be connected to the hinge body 122, with at least one of the adjacent hinge bodies 122 connected to the traction member 142. Alternatively, it can be connected to the rotating shaft 124, with at least one of the adjacent rotating shafts 124 connected to the traction member 142.

[0057] like Figure 1 and Figure 2 As shown, in one possible implementation, the traction member 142 is connected to each hinge body 122; or the traction member 142 is connected to each pivot 124.

[0058] Specifically, the traction member 142 can be connected to each hinge body 122, so that when the traction member 142 moves, each hinge body 122 is pulled by the traction member 142, thereby making the movement of the hinge assembly 120 smoother and improving the stability of the movement of the hinge assembly 120.

[0059] The traction member 142 can be connected to each rotating shaft 124, so that when the traction member 142 moves, each rotating shaft 124 is pulled by the traction member 142, thereby making the movement of the hinge assembly 120 smoother and improving the stability of the movement of the hinge assembly 120.

[0060] like Figure 1 and Figure 2 As shown, in one possible implementation, the drive assembly 140 further includes an auxiliary mechanism 146, which is disposed in the hinge assembly 120 and arranged along the extension direction of the hinge assembly 120. The auxiliary mechanism 146 has a supporting state and a curled state. When the drive member 144 drives the traction member 142 to move, so that the hinge assembly 120 is in the curled state, the auxiliary mechanism 146 is in the curled state. When the drive member 144 drives the traction member 142 to move, so that the hinge assembly 120 is in the straight state, the auxiliary mechanism 146 is in the supporting state.

[0061] Specifically, the drive assembly 140 also includes an auxiliary mechanism 146, which is disposed on the hinge assembly 120 along the extension direction of the hinge assembly 120. The auxiliary mechanism 146 has a supporting state and a curled state, and thus the auxiliary mechanism 146 can assist the drive member 144 and the traction member 142 in driving the hinge assembly 120 to move.

[0062] When the traction member 142 is in an unequal length state, the greater the length difference between the two ends of the traction member 142, the smaller the diameter of the hinge assembly 120 and the flexible screen assembly 130 in the wound state, and the greater the friction and wear of the surface contact between the hinge bodies 122. Therefore, the auxiliary mechanism 146 is provided to increase the driving force on the hinge assembly 120. Under the combined action of the tension of the traction member 142 and the auxiliary force of the auxiliary mechanism 146, the hinge assembly 120 can be wound to a smaller state, and the stiffness of the hinge assembly 120 in the straight state can also be improved.

[0063] Specifically, as the hinge assembly 120 transitions from a coiled state to a straight state, the driving member 144 pulls the traction member 142 from an equal-length state to an unequal-length state. Simultaneously, the auxiliary mechanism 146 switches from a coiled state to a supporting state, causing the hinge assembly 120 to gradually unfold and eventually reach a straight state. The auxiliary mechanism 146 can operate after the driving member 144 has started working, or it can operate before the driving member 144 has started working.

[0064] The hinge assembly 120 transitions from a straight state to a coiled state. The driving member 144 pulls the traction member 142 from an unequal-length state to an equal-length state. Simultaneously, the auxiliary mechanism 146 switches from a supporting state to a coiled state, causing the hinge assembly 120 to gradually coil and ultimately reach a coiled state. The auxiliary mechanism 146 can operate after the driving member 144 has started working, or it can operate before the driving member 144 has started working.

[0065] like Figure 1 and Figure 2 As shown, in one possible implementation, the auxiliary mechanism 146 includes: a pipe body 148; and a pump body 150 connected to the pipe body 148. After the pump body 150 pumps the medium into the pipe body 148, the auxiliary mechanism 146 is in a supported state. After the pump body 150 pumps the medium out of the pipe body 148, the auxiliary mechanism 146 is in a wound state. The pump body 150 is disposed on the housing 110.

[0066] Specifically, the auxiliary mechanism 146 includes a tube 148 and a pump body 150. The tube 148 is located in the hinge assembly 120 and is arranged along the extension direction of the hinge assembly 120.

[0067] like Figure 1 As shown, the pump body 150 pumps the medium out of the pipe body 148. Since there is no medium inside the pipe body 148, the pipe body 148 changes to a coiled state. Then, the pipe body 148, the traction member 142 and the driving member 144 cooperate to provide driving force for the hinge assembly 120, so that the hinge assembly 120 switches to the coiled state more smoothly.

[0068] When there is no medium inside the tube 148, the tube 148 is in a curled state.

[0069] like Figure 2 As shown, the pump body 150 is connected to the pipe body 148. The pump body 150 pumps the medium into the pipe body 148. The medium can provide support for the pipe body 148, thereby increasing the rigidity of the pipe body 148 and reducing the possibility of the pipe body 148 being compressed. In other words, the auxiliary mechanism 146 is in a supporting state at this time, which can provide support for the hinge assembly 120, thereby keeping the hinge assembly 120 in a straight state. The support of the pipe body 148 prevents the flexible screen assembly 130 from exhibiting wavy patterns.

[0070] The pump body 150 can pump either gas or liquid.

[0071] Furthermore, during the process of the hinge assembly 120 changing from a coiled state to a straight state, the drive assembly 140 operates, causing the drive assembly 140 to change from a first state to a second state. That is, the drive member 144 drives the traction member 142 to switch from an unequal length state to an equal length state. Meanwhile, the pump body 150 pumps the medium into the pipe body 148, causing the pipe body 148 to change from a coiled state to a supported state. As a result, the hinge assembly 120 gradually unfolds. After the drive assembly 140 is fully in the second state, that is, the drive member 144 drives the traction member 142 to be in an equal length state and the pipe body 148 is in a supported state, the hinge assembly 120 is fully unfolded and in a straight state.

[0072] During the process of hinge assembly 120 changing from a straight state to a coiled state, drive assembly 140 operates, causing drive assembly 140 to change from a second state to a first state. That is, drive member 144 drives traction member 142 to switch from an equal-length state to an unequal-length state. Meanwhile, pump body 150 extracts medium from pipe body 148, causing pipe body 148 to change from a supported state to a coiled state. As a result, hinge assembly 120 gradually coils. After drive assembly 140 is completely in the first state, that is, drive member 144 drives traction member 142 to an unequal-length state and pipe body 148 is in a coiled state, hinge assembly 120 is completely coiled and is in a coiled state.

[0073] The rotating shaft 124 can be provided with mounting holes in its radial direction, and the tube 148 passes through the mounting holes, so that the tube 148 can better cooperate with the hinge assembly 120. In addition, the support points of the tube 148 for the hinge assembly 120 are increased, thereby improving the reliability of the hinge assembly 120.

[0074] Furthermore, when the auxiliary mechanism 146 is in a curled state, the tube 148 may be completely devoid of medium or may contain a portion of medium.

[0075] As one possible implementation, the pump body 150 is a liquid pump.

[0076] Specifically, the pump body 150 is a liquid pump, that is, the pump body 150 delivers or extracts liquid into the pipe body 148. The liquid has strong compressive strength, which increases the rigidity of the pipe body 148 in the supported state and increases the rigidity of the hinge assembly 120 in the straight state.

[0077] When the medium inside the tube 148 is pumped out, air may enter the tube 148, causing the winding force to differ from that at the factory. At this time, the processor 170 can correct the extraction force of the pump body 150 on the software side, thereby achieving a consistent extraction force and further ensuring that the diameter of the tube 148 is consistent when it is in the coiled state, thus ensuring the consistency of the operation of the tube 148 and the traction component 142.

[0078] like Figure 5 As shown, in one possible implementation, the electronic device 100 further includes: a length detection component 160 for detecting the length of the traction member 142; and a processor 170, wherein the length detection component 160 and the drive member 144 are both electrically connected to the processor 170, and the processor 170 controls the motion parameters of the drive member 144 according to the length of the traction member 142.

[0079] Specifically, the electronic device 100 also includes a length detection component 160 and a processor 170. The length detection component 160 is used to detect the length of the traction member 142 in the screen module. Furthermore, both the length detection component 160 and the drive member 144 are connected to the processor 170. Since the traction member 142 will inevitably change in length during prolonged use, the processor 170 controls the motion parameters of the drive member 144 based on the length of the traction member 142. This allows the drive member 144 to more precisely control the traction member 142 to switch between equal and unequal length states on both sides, ensuring that the length difference of the traction member 142 remains consistent in the unequal length state, and thus maintaining a consistent diameter of the hinge assembly 120 in the wound state over a long period.

[0080] like Figure 4 As shown, in one possible implementation, a protective film layer 180 is provided on the side of the flexible screen assembly 130 away from the hinge assembly 120, and a steel sheet 182 is provided on the side of the flexible screen assembly 130 facing the hinge. The steel sheet 182 is attached to the hinge assembly 120 by adhesive 184. Foam 186 is provided on the side of the hinge assembly 120 away from the flexible screen assembly 130 and is attached to the hinge assembly 120.

[0081] The protective film layer 180 can be a glass layer and / or a polyethylene terephthalate (PET) layer, etc. Attaching the flexible screen assembly 130 only to a portion of the hinge assembly 120 is for better stress relief during bending and to reduce the force required to drive bending. Furthermore, on the opposite side of the flexible screen assembly 130, a protective layer of foam 186 and / or PET is attached to the hinge assembly 120 to optimize feel and touch.

[0082] The protective film layer 180 can also be a composite layer of ultra-thin glass and polyethylene terephthalate (PET).

[0083] like Figure 1 and Figure 2 As shown, in one possible implementation, the electronic device 100 further includes: a button 188 disposed on the housing 110 and electrically connected to the processor 170; and a battery 190 disposed within the housing 110 for powering various components of the electronic device 100. Specifically, the button 188 can be a power button, a volume button, or a separate button 188. Triggering the button 188 controls the switching of the state of the hinge assembly 120. Furthermore, the button 188 can also be a fingerprint recognition device. Users can control the hinge assembly 120 via fingerprint, thereby improving user security.

[0084] like Figure 1 and Figure 2 As shown, in one possible implementation, a secondary screen 192 may be provided on the side of the housing 110 away from the hinge assembly 120. The secondary screen 192 can display prompt information, etc., when the hinge assembly 120 is in a wound state.

[0085] As one possible implementation, the electronic device 100 includes mobile phones, tablets, laptops, e-books, or wearable devices.
