[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] Since foldable electronic devices require the use of a hinge assembly, when the existing hinge assembly is in use, the moving parts may shake during movement due to the existence of assembly gaps, resulting in noise and unstable movement, which affects the service life of the hinge assembly.

[0020] Based on this, the inventor of the present application has proposed an electronic device with a hinge assembly after long-term research, which can avoid shaking and noise during rotation.

[0021] The content of this application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, this embodiment provides an electronic device 10. The electronic device 10 in this application can be a mobile phone or a smart phone (for example, a phone based on iPhone TM, a phone based on Android TM), a portable gaming device (for example, Nintendo DS TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), a laptop, a PDA, a portable Internet device, a music player, and a data storage device, other handheld devices, etc. The electronic device 10 can also be other wearable devices.

[0023] Please also read Figure 1 and Figure 2 This embodiment provides an electronic device 10, which is foldable. Figure 1 The electronic device 10 is shown in the unfolded state. Figure 2 The electronic device 10 is shown in a folded state. The electronic device 10 provided in this embodiment is described by taking a mobile phone as an example.

[0024] The electronic device 10 may further include a display screen 30, a battery 50, etc., and the mainboard 40 and the battery 50 are both disposed inside the electronic device 10. The electronic device 10 may also be provided with a front camera (not shown), which is disposed on one side of the electronic device 10 where the display screen 30 is disposed.

[0025] Please continue reading Figure 1 and Figure 2The electronic device 10 is foldable. Specifically, the electronic device 10 includes a first frame 100, a second frame 200, and a hinge assembly 300. The hinge assembly 300 is connected between the first frame 100 and the second frame 200. The first frame 100 is folded or unfolded relative to the second frame 200 through the hinge assembly 300. The folding means that the first frame 100 and the second frame 200 are stacked in an overlapping posture. During the relative folding of the first frame 100 and the second frame 200, the hinge assembly 300 may be bent. In some embodiments, the first frame 100 and the second frame 200 are axially symmetrical along the hinge assembly 300, that is, when the first frame 100 and the second frame 200 are in the folded state, the first frame 100 and the second frame 200 can completely overlap, that is, the areas of the first frame 100 and the second frame 200 are approximately equal. In some other implementations, the first frame body 100 and the second frame body 200 may not completely overlap when in the folded state. In this case, the areas of the first frame body 100 and the second frame body 200 may not be equal, which is not limited in this embodiment.

[0026] The first frame 100 has a first side and a second side opposite to the first side, wherein the first side and the second side are stacked along the thickness direction of the first frame 100. In some embodiments, the first frame 100 may include a middle frame and a back cover, the back cover is mounted on the middle frame to form a cavity, and the back cover may be assembled with the middle frame by bonding or clamping, and in some embodiments, the back cover may be made of glass, ceramic, plastic, metal, or other materials.

[0027] The second frame 200 has a third side and a fourth side opposite to the third side, wherein the third side and the fourth side are stacked along the thickness direction of the second frame 200. In some embodiments, the second frame 200 can also be composed of a middle frame and a back cover, the back cover is installed on the middle frame to form a cavity, and the back cover can be assembled with the middle frame by bonding or clamping. In some embodiments, the back cover can be made of glass, ceramic, plastic, metal, etc. When the first frame 100 and the second frame 200 are in a flattened state, the first side can be flush with the third side, and the second side can be flush with the fourth side.

[0028] In one embodiment, the display screen 30 may be a foldable flexible display screen, which is continuously assembled on the first frame 100 and the second frame 200. When the first frame 100 and the second frame 200 are folded, the display screen 30 is folded accordingly. It is understandable that when the first frame 100 and the second frame 200 are in a relatively folded state, the display screen 30 may be located on the inside and not exposed, that is, the electronic device 10 is an inward folding electronic device at this time, and the display screen 30 may also be located on the outside and exposed on the surface of the electronic device 10, that is, the electronic device 10 is an outward folding electronic device at this time.

[0029] In another embodiment, the display screen 30 may be two, and the two display screens 30 are respectively arranged on the first frame 100 and the second frame 200. In this case, the display screen 30 may use an LCD (Liquid Crystal Display) screen for displaying information, and the LCD screen may be a TFT (Thin Film Transistor) screen or an IPS (In-Plane Switching) screen or an SLCD (Splice Liquid Crystal Display) screen. In other embodiments, the display screen 30 may use an OLED (Organic Light-Emitting Diode) screen for displaying information, and the OLED screen may be an AMOLED (Active Matrix Organic Light Emitting Diode) screen or a Super AMOLED (Super Active Matrix Organic Light Emitting Diode) screen or a SuperAMOLED Plus (Super Active Matrix Organic Light Emitting Diode Plus, Magic Screen) screen, which will not be described in detail here.

[0030] In addition, the electronic device 10 may further include a secondary screen (not shown), which is arranged in the first frame 110 or the second frame 120 and is located on the side opposite to the display screen 30. The secondary screen may be one or more, and this embodiment does not limit this.

[0031] Figure 4 A cross-sectional structure of a rotating shaft assembly 300 is shown. Figure 4 The hinge assembly 300 includes a base 320, a hinge 310, and rotating parts 330 arranged on both sides of the base 320, wherein the rotating parts 330 arranged on both sides of the base 320 are respectively used to connect the first frame 100 and the second frame 200, the hinge 310 is rotatably arranged on the base 320, and the rotating part 330 rotates synchronously with the hinge 310, thereby driving the first frame 100 and the second frame 200 to fold or unfold relative to each other.

[0032] Specifically, the base 320 is used to install and accommodate the rotating shaft 310 and part of the rotating part 330. In this embodiment, the rotating shaft 310 includes a first rotating shaft 311 and a second rotating shaft 312. The first rotating shaft 311 and the second rotating shaft 312 are arranged side by side, and the extension direction of the first rotating shaft 311 is the same as the extension direction of the second rotating shaft 312 and the extension direction of the rotation axis. The first rotating shaft 311 and the second rotating shaft 312 rotate synchronously. Specifically, the first rotating shaft 311 and the second rotating shaft 312 are engaged by gears, so that the first rotating shaft 311 and the second rotating shaft 312 can rotate synchronously. The first frame 100 is located on a side of the first rotating shaft 311 away from the second rotating shaft 312, and the second frame 200 is located on a side of the second rotating shaft 312 away from the first rotating shaft 311.

[0033] There are multiple rotating parts 330, and multiple rotating parts 330 are arranged on both sides of the base 320. The rotating parts 330 can be used to connect the first frame 100 or the second frame 200, and the rotating parts 330 can also be used to install the display screen. The number of rotating parts 330 can be an even number, and the even number of rotating parts 330 are symmetrically distributed on both sides of the base 320. Specifically, in this embodiment, the number of rotating parts 330 is 4, of which 2 rotating parts 330 are used to connect the first frame 100, and the 2 rotating parts 330 are located on the side of the first rotating shaft 311 away from the second rotating shaft 312, and are respectively close to the two ends of the first rotating shaft 311. The remaining 2 rotating parts 330 are used to connect the second frame 200, and the 2 rotating parts 330 are located on the side of the second rotating shaft 312 away from the first rotating shaft 311, and are respectively close to the two ends of the second rotating shaft 312.

[0034] Each rotating part 330 includes a rotating member 340, a guide rail member 360 and an elastic member 380. The rotating member 340 is rotatably connected to the base 320 and rotates synchronously with the rotating shaft 310. The guide rail member 360 is rotatably connected to the base 320. The elastic member 380 elastically abuts between the guide rail member 360 and the rotating member 340. The rotating member 340 and the guide rail member 360 can move relative to each other. The elastic member 380 is arranged between the guide rail member 360 and the rotating member 340 so that the guide rail member 360 and the rotating member 340 remain stable in the non-movement direction to prevent the rotating member 340 from shaking during the sliding process relative to the guide rail member 360. The non-movement direction refers to a direction other than the relative sliding direction of the guide rail member 360 and the rotating member 340.

[0035] The guide rail member 360 is rotatably connected to the base 320, and is used to connect to the first frame body 100 or the second frame body 200, so that the first frame body 100 or the second frame body 200 can rotate relative to the base 320. Specifically, the guide rail member 360 located on the side of the first rotating shaft 311 away from the second rotating shaft 312 is connected to the first frame body 100, for example, it can be connected to the first frame body 100 by screws; the guide rail member 360 of the rotating part 330 located on the side of the second rotating shaft 312 away from the first rotating shaft 311 is connected to the second frame body 200, for example, it can be connected to the second frame body 200 by screws.

[0036] The rotation axis of the rotating member 340 is inconsistent with the rotation axis of the guide member 360 , so the rotation path of the rotating member 340 relative to the base 320 is different from the rotation path of the guide member 360 relative to the base 320 , and there is a path difference. Figure 5 The structure of the rotating part 330 in the rotating shaft assembly 300 is shown. Figure 4 and Figure 5 The guide rail member 360 is provided with a guide groove 364, and the rotating member 340 is at least partially slidably embedded in the guide groove 364. Since there is a path difference between the rotation path of the rotating member 340 relative to the base 320 and the rotation path of the guide rail member 360 relative to the base 320, the rotating member 340 and the guide rail member 360 will slide relative to each other. In order to make the relative sliding between the rotating member 340 and the guide rail member 360 smooth, there is an assembly gap between the portion of the rotating member 340 embedded in the guide groove 364 and the guide groove 364.

[0037] Please continue reading Figure 5 In this embodiment, the guide rail member 360 includes a bottom plate 361, a first baffle plate 362, and a second baffle plate 363. The bottom plate 361 is arranged opposite to the rotating member 340. The first baffle plate 362 and the second baffle plate 363 are connected to the bottom plate 361 and arranged opposite to each other. An accommodation space is formed between the first baffle plate 362 and the second baffle plate 363, and the rotating member 340 can be embedded in the accommodation space. A guide groove 364 is formed on the first baffle plate 362 and the second baffle plate 363. Specifically, the first baffle plate 362 and the second baffle plate 363 are both provided with the guide groove 364, and the guide groove 364 provided on the first baffle plate 362 is opposite to the guide groove 364 provided on the second baffle plate 363. In this embodiment, the guide rail member 360 may further include a mounting portion 366, which is connected to the bottom plate 361 and is rotatably assembled with the base 320 through the rotating connecting member 420.

[0038] The guide groove 364 is configured as a substantially arc-shaped groove, and the guide groove 364 is adapted to the rotation track of the rotating member 340, so that the rotating member 340 can slide along the extension direction of the guide groove 364. The rotating shaft assembly 300 further includes a support plate 410, which is assembled and connected to the guide rail member 360 and relatively fixed, and is used to install the display screen. The support plate 410 is opposite to the bottom plate 361, and the first baffle plate 362 and the second baffle plate 363 are located between the bottom plate 361 and the support plate 410.

[0039] Please combine Figure 4 and Figure 5 In this embodiment, the rotating member 340 includes a rotating mounting portion 341, an assembly portion 342, and a sliding portion 343. The rotating mounting portion 341 is rotatably disposed on the base 320 and rotates synchronously with the rotating shaft 310. Specifically, the rotating mounting portion 341 can be installed on the base 320 by pivoting, and at the same time, the rotating mounting portion 341 and the rotating shaft 310 are meshed through gears. Specifically, the rotating mounting portion 341 of the rotating portion 330 located on the side of the first rotating shaft 311 away from the second rotating shaft 312 can be meshed with the first rotating shaft 311 through gears, thereby achieving the purpose of synchronous rotation with the first rotating shaft 311; the rotating mounting portion 341 of the rotating portion 330 located on the side of the second rotating shaft 312 away from the first rotating shaft 311 can be meshed with the second rotating shaft 312 through gears, thereby achieving the purpose of synchronous rotation with the second rotating shaft 312.

[0040] The assembly portion 342 is connected to the rotating mounting portion 341 and extends toward the side of the base 320. The sliding portion 343 is connected to the assembly portion 342 and is used to assemble with the guide rail member 360. Specifically, the assembly portion 342 extends into the accommodation space between the first baffle plate 362 and the second baffle plate 363. The sliding portion 343 is connected to the assembly portion 342 and embedded in the guide groove 364. The sliding portion 343 can be configured as a columnar structure and can slide along the extension direction of the guide groove 364. In order to ensure that the sliding portion 343 can slide more smoothly relative to the guide rail member 360, the sliding portion 343 and the guide groove 364 have a certain assembly gap.

[0041] Please continue reading Figure 5 The elastic member 380 elastically abuts between the guide member 360 and the rotating member 340, so that an elastic force is generated between the guide member 360 and the rotating member 340. The direction of the elastic force can be roughly perpendicular to the bottom plate 361 of the guide member 360. The elastic force causes the guide member 360 and the rotating member 340 to repel each other in the thickness direction of the electronic device, and causes the sliding part 343 to contact with the wall surrounding the guide groove 364, thereby preventing the sliding part 343 from shaking in the guide groove 364.

[0042] Specifically in this embodiment, the elastic member 380 is abutted between the bottom plate 361 and the assembly portion 342. The elastic member 380 can be fixed to the guide member 360 or the rotating member 340.

[0043] As a more specific implementation, Figure 6 shows a structure of an elastic member 380, Figure 7 Shows Figure 6 For the cross-sectional structure of the middle elastic member 380, please refer to Figure 6 and Figure 7 The elastic member 380 includes a connecting portion 381 and a cantilever 386 connected to each other. The connecting portion 381 is connected to the guide rail member 360. The cantilever 386 elastically abuts between the guide rail member 360 and the rotating member 340 to generate an elastic force between the guide rail member 360 and the rotating member 340. Specifically, the cantilever 386 abuts between the bottom plate 361 of the guide rail member 360 and the assembly portion 342 of the rotating member 340. The cantilever 386 is an elastically deformable structure. After abutting with the guide rail member 360 and the rotating member 340, an elastic force is generated on the guide rail member 360 and the rotating member 340. The cantilever 386 can be set to various structures, which are not limited in this embodiment.

[0044] Specifically in this embodiment, the cantilever 386 is a roughly plate-like structure, and the cantilever 386 includes a first protrusion 387 and a second protrusion 388. The protrusion directions of the first protrusion 387 and the second protrusion 388 are opposite. The first protrusion 387 abuts against the guide rail member 360, and the second protrusion 388 abuts against the rotating member 340. In this way, abutment is formed between the cantilever 386 and the guide rail member 360 and the rotating member 340. Since the protrusion directions of the first protrusion 387 and the second protrusion 388 are opposite, the forces acting on the cantilever 386 by the guide rail member 360 and the forces acting on the rotating member 340 are opposite in direction, and the cantilever 386 can maintain a stable state. It can be understood that the force exerted by the cantilever 386 on the guide member 360 and the force exerted on the rotating member 340 are not along the sliding direction of the rotating member 340 relative to the guide member 360, that is, the force exerted by the cantilever 386 on the guide member 360 and the force exerted on the rotating member 340 are both along the non-movement direction of the guide member 360 and the rotating member 340, and therefore will not interfere with the relative sliding of the guide member 360 and the rotating member 340.

[0045] Furthermore, in order to improve the abutment effect of the cantilever 386, the end 389 of the cantilever 386 away from the connecting portion 381 abuts against the guide rail member 360, so that the contact points between the cantilever 386 and the guide rail member 360 can be increased, thereby improving stability. Among them, the second protrusion 388 can be located between the first protrusion 387 and the end 389, so that the first protrusion 387, the second protrusion 388 and the end 389 can form a triangular structure, making the structure of the cantilever 386 more stable. Of course, it can be understood that in some other embodiments, the end 389 of the arm away from the connecting portion 381 can also abut against the rotating member 340, and at the same time, the first protrusion 387 is located between the second protrusion 388 and the end 389, which is not limited in this embodiment.

[0046] In this embodiment, the connecting portion 381 is connected to the guide rail member 360. Specifically, the connecting portion 381 is connected to the bottom plate 361 of the guide rail member 360. This arrangement is conducive to assembling and fixing the elastic member 380. At the same time, since the guide rail member 360 is relatively fixed relative to the first frame 100 or the second frame 200, connecting the connecting portion 381 to the guide rail member 360 can be conducive to maintaining the stability of the elastic member 380, and will not cause more mechanical fatigue to the elastic member 380, resulting in failure. The connecting portion 381 can be connected to the guide rail member 360 by bonding, magnetic adsorption, etc., or by fasteners such as screws, which are not limited in this embodiment.

[0047] In this embodiment, the connecting portion 381 is clamped to the guide member 360, specifically, the connecting portion 381 is clamped to the bottom plate 361 of the guide member 360. The clamping method is more convenient during assembly and easy to maintain. As a more specific implementation, the connecting portion 381 is provided with a clamping groove 384, and the clamping groove 384 is clamped to the edge of the guide member 360, that is, the bottom plate 361 of the guide member 360 is partially embedded in the clamping groove 384, so that the connecting portion 381 is suspended from the guide member 360. And the clamping groove 384 can also be configured to have an elastic structure, so that an elastic extrusion force is generated between the connecting portion 381 and the guide member 360, so that the elastic member 380 can be more stably fixed on the guide member 360.

[0048] Specifically, the connecting portion 381 includes a first connecting plate 382 and a second connecting plate 383, the first connecting plate 382 is connected to the cantilever 386, one end of the second connecting plate 383 is connected to the first connecting plate 382 and is bent relative to the first connecting plate 382, ​​and a slot 384 is formed between the first connecting plate 382 and the second connecting plate 383. In order to enable the slot 384 to be more stably fixed to the guide rail member 360, the entrance of the slot 384 is set to be narrower, so that the guide rail member 360 can be stably clamped by the first connecting plate 382 and the second connecting plate 383 after being inserted into the slot 384.

[0049] In order to further improve the fixing effect of the elastic member 380, please combine Figure 7 and Figure 8 The bottom plate 361 of the guide rail member 360 includes a first surface and a second surface facing each other, the first surface faces the rotating member 340, and the second surface is provided with a fixing groove 367. When the edge of the bottom plate 361 is inserted into the slot 384, the end of the second connecting plate 383 away from the first connecting plate 382 is engaged in the fixing groove 367, so that the connecting portion 381 is difficult to be separated from the guide rail member 360, ensuring that the elastic member 380 can continuously act on the guide rail member 360 and the rotating member 340. Preferably, the end of the second connecting plate 383 away from the first connecting plate 382 forms an elastic protrusion 385, and the elastic protrusion 385 is embedded in the fixing groove 367. At the same time, the edge of the elastic protrusion 385 can be located outside the fixing groove 367, so that when the elastic member 380 needs to be disassembled, it is only necessary to pull the edge of the elastic protrusion 385, which is faster and more convenient.

[0050] In order to better fix the elastic member 380 and prevent the elastic member 380 from sliding along the bottom plate 361 after being clamped on the bottom plate 361, the elastic member 380 may also include a stopper ear 390, which is connected to the side edge of the connecting portion 381. In this embodiment, there are two stopper ears 390, which are respectively connected to the side edges of the connecting portion 381. The stopper ears 390 may abut against the first baffle plate 362 or the second baffle plate 363, thereby limiting the elastic member 380 and preventing the elastic member 380 from shifting or shaking, thereby affecting the stability between the guide member 360 and the rotating member 340. At the same time, by providing the stopper ears 390, foolproof performance can also be formed to avoid assembly errors by operators during assembly.

[0051] It is understandable that the number of the elastic member 380 may be one or more. When there are more than one elastic member 380 , the multiple elastic members 380 may be arranged at intervals, which is not limited in this embodiment.

[0052] In some other embodiments, the elastic member 380 may also be configured in other forms. For example, in one embodiment, the elastic member 380 may be a spring disposed between the guide member 360 and the rotating member 340. In other embodiments, the elastic member 380 may also be elastic rubber, silicone, etc., disposed between the guide member 360 and the rotating member 340, which is not limited in this embodiment.

[0053] Please refer again Figure 1The electronic device 10 further includes a mainboard 40 and a battery 50. The mainboard 40 can be arranged in the first frame 100, and the battery 50 can be arranged in the second frame 200. In order to improve the endurance of the electronic device 10, the battery 50 can be a large-capacity battery 50, for example, the area of ​​the battery 50 can cover at least 80% of the area of ​​the second frame 200. The mainboard 40 can be electrically connected to the battery 50 to obtain power supply. Various processors 60, memories, and other devices can be integrated on the mainboard 40, so when the mainboard 40 is working, more heat will be generated. In one embodiment, the electronic device 10 can also include a secondary battery (not shown in the figure), which can be arranged in the first frame 100 and adjacent to the mainboard 40. The secondary battery can be electrically connected to the mainboard 40, and the secondary battery can supply power to the mainboard 40, so that the battery 50 does not need to be connected to the first frame 100 to supply power to the electrical components in the first frame 100. The battery 50 can be electrically connected to the display screen to supply power to the display screen.

[0054] Among them, the processor 60 may include one or more processing cores. The processor 60 uses various interfaces and lines to connect various parts within the entire electronic device 10, and executes various functions and processes data of the electronic device 1010 by running or executing instructions, programs, code sets or instruction sets stored in the memory, and calling data stored in the memory. Optionally, the processor 60 can be implemented in at least one hardware form of digital signal processing (Digital Signal Processing, DSP), field programmable gate array (Field-Programmable Gate Array, FPGA), and programmable logic array (Programmable Logic Array, PLA). The processor 60 can integrate one or a combination of a central processing unit 60 (Central Processing Unit, CPU), a graphics processing unit 60 (Graphics Processing Unit, GPU) and a modem. Among them, the CPU mainly processes the operating system, user interface and application programs; the GPU is responsible for rendering and drawing display content; and the modem is used to process wireless communications. It can be understood that the above-mentioned modem may not be integrated into the processor 60, but may be implemented separately through a communication chip.

[0055] The hinge assembly 300 and the electronic device 10 provided in the embodiment of the present application are provided with an elastic member 380 between the rotating member 340 and the guide member 360. The elastic member 380 can abut against the rotating member 340 and the guide member 360, so that the positions of the rotating member 340 and the guide member 360 remain fixed in the non-movement direction. In this way, the rotating member 340 and the guide member 360 will not shake in the non-movement direction during the relative sliding process, thereby avoiding noise during the rotation process and avoiding collision and damage of the rotating member 340 and the guide member 360 due to shaking, which is beneficial to extending the life of the hinge assembly 300. At the same time, since the action direction of the elastic member 380 is the non-movement direction of the guide member 360 and the rotating member 340, it does not affect the relative sliding of the guide member 360 and the rotating member 340. When the user folds the first frame body 100 and the second frame body 200, the elastic force of the elastic member 300 can also have a certain damping effect, so that the first frame body 100 and the second frame body 200 remain suspended.

[0056] It should also be noted that, in this embodiment, expressions such as "first", "second", "third", and "fourth" are only used for distinction and do not represent limitations on the specific structure.

[0057] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
