Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to an electronic device. Background Art

[0002] With the rapid development of the electronics industry, electronic devices have more and more functions. In order to meet the demand for display area of ​​electronic devices in different scenarios, foldable screen electronic devices have been widely used in recent years.

[0003] In the prior art, the display screen of a foldable electronic device is usually set as a large-sized flexible screen. The flexible screen is bent to meet the user's demand for a large-sized screen with a small footprint. However, a large-sized flexible screen not only has strict production process requirements, low production efficiency, and high production costs, but also, in actual application, the flexible screen needs to be bent repeatedly, which can easily cause damage to the flexible screen, resulting in high maintenance costs for electronic devices. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem that the flexible screen of existing foldable electronic devices is easily damaged and has high cost.

[0005] An embodiment of the present application provides an electronic device, the electronic device comprising: a first screen body, a second screen body and a hinge structure;

[0006] The first screen body and the second screen body are connected via the hinge structure and can be switched between a folded state and an unfolded state;

[0007] The hinge structure includes: a main hinge, and connecting members arranged on both sides of the main hinge and rotatably connected to the main hinge respectively; one of the connecting members is rotatably connected to the first screen body, and the other connecting member is rotatably connected to the second screen body;

[0008] When the electronic device is in the folded state, the first screen body and the second screen body are stacked, and the two connecting members are stacked; when the electronic device is in the unfolded state, the screens of the first screen body and the second screen body are spliced ​​together, or the screens of the first screen body and the second screen body are separated, and the two connecting members are sandwiched between the first screen body and the second screen body.

[0009] In the embodiment of the present application, since the first screen body and the second screen body are connected by the main hinge and the connecting parts on both sides thereof, the first screen body and the second screen body can be respectively rotated along the main hinge, the first screen body and the second screen body through the connecting parts, so that the first screen body and the second screen body can be switched between a folded state and an unfolded state. Therefore, in the embodiment of the present application, the screens in the first screen body and the second screen body can both use hard screens (LCD screens or OLED screens) with lower costs than flexible screens. The large-screen function can be achieved by splicing the first screen body and the second screen body, or the first screen body and the second screen body can be separated so that the two first screen bodies and the second screen bodies can be used and work separately. In this way, not only can the screen cost and damage rate of the electronic device be reduced, but also the functionality and fun of screen use can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] 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 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.

[0034] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0035] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0036] The electronic device described in the embodiment of the present application may be a smart phone, a computer, a multimedia player, an electronic reader, a wearable device, etc. In the embodiment of the present application, the electronic device is a smart phone as an example to illustrate its structure and principle, and other references can be made.

[0037] Reference Figures 1 to 12 , showing a schematic diagram of different states of the electronic device described in an embodiment of the present application.

[0038] In the embodiment of the present application, the electronic device may specifically include: a first screen body 10, a second screen body 20 and a hinge structure 30; the first screen body 10 and the second screen body 20 are connected by the hinge structure 30 to switch between a folded state and an unfolded state; the hinge structure 30 includes: a main hinge 31, and connecting members 32 arranged on both sides of the main hinge 31 and rotatably connected to the main hinge 31 respectively; one of the connecting members 32 is rotatably connected to the first screen body 10, and the other connecting member 32 is rotatably connected to the second screen body 20; when the first screen body 10 and the second screen body 20 are in a folded state, the first screen body 10 and the second screen body 20 are stacked, and the two connecting members 32 are stacked; when the electronic device is in an unfolded state, the screens of the first screen body 10 and the second screen body 20 are spliced ​​together, or the screens of the first screen body 10 and the second screen body 20 are separated, and two connecting members 32 are sandwiched between the first screen body and the second screen body.

[0039] In the embodiment of the present application, the screens in the first screen body 10 and the second screen body 20 can both use screens with lower costs than flexible screens (LCD screens or OLED screens). The large screen function is achieved by splicing the screens of the first screen body 10 and the second screen body 20. The first screen body 10 and the second screen body 20 are separated to achieve the function of using and working the two screens separately. This can not only reduce the screen cost and damage rate of the electronic device, but also improve the functionality and fun of screen use.

[0040] like Figures 1 to 12 As shown, the electronic device described in the embodiment of the present application can also be understood as a folding screen mobile phone. In the embodiment of the present application, the screens of the first screen body 10 and the second screen body 20 can be conventional non-foldable screens, such as LCD screens, OLED screens, etc. In the embodiment of the present application, the screens of the first screen body 10 and the second screen body 20 can be hard screens or soft screens, which is not limited in the embodiment of the present application.

[0041] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the first screen body 10 and the second screen body 20 can realize a large screen function by splicing the screens. Figures 3 to 5 As shown, the first screen body 10 and the second screen body 20 can also be separated and used as a separate screen to achieve their respective corresponding functions and effects.

[0042] like Figure 1 As shown, a front camera 101 can also be provided on either the first screen body 10 or the second screen body 20 to realize the front camera function of the electronic device. In addition, an integrated loud speaker 103 with a large volume can also be provided on both the first screen body 10 and the second screen body 20 to improve the user's convenience. It should be noted that in the embodiment of the present application, the speaker 103 of the electronic device can be used to answer low-decibel voices and can also be used as a high-decibel external speaker. In voice mode, any speaker 103 on the first screen body 10 and the second screen body 20 works. For example, which screen the user is using, the speaker 103 corresponding to which screen works; in external speaker mode, the speakers 103 on both the first screen body 10 and the second screen body 20 can work together as a stereo function output to enhance the sound quality effect. In addition, the external earpiece and the internal earpiece of any speaker 103 can be simply interconnected in structure, so that the effect of external or internal answering can be achieved, without the need to add an additional external speaker, which is beneficial to cost saving of electronic equipment.

[0043] In an embodiment of the present application, when the electronic device is in a folded state, it may include: a first folded state and a second folded state; when the electronic device is in the first folded state, the screens of the first screen body 10 and the second screen body 20 are opposite to each other; when the electronic device is in the second folded state, the screens of the first screen body 10 and the second screen body 20 are back to back; at least one of the first screen body 10 and the second screen body 20 drives the connecting member 32 connected thereto to rotate around the main hinge 31, so that the electronic device switches between the first folded state and the second folded state.

[0044] In the embodiment of the present application, the first folding state can also be understood as positive folding, that is, the first screen body 10 and the second screen body 20 are both in a position and an angle with respect to the connecting member 32 connected thereto remain unchanged, at least one of the first screen body 10 and the second screen body 20 is folded inwardly with the main hinge 31 as the axis to be stacked, and the screens of the first screen body 10 and the second screen body 20 are both invisible to the outside (such as Figures 6 to 8 The second folding state can be understood as a reverse folding state, which can be understood as a state in which the first screen body 10 and the second screen body 20 are both in a state in which the position and angle of the connecting member 32 connected to them remain unchanged, at least one of the first screen body 10 and the second screen body 20 is folded outwardly with the main hinge 31 as the axis to be stacked, and the screens of the first screen body 10 and the second screen body 20 are both visible to the outside (as shown in FIG. Figures 3 to 5 In other words, when the electronic device switches between the first folding state and the second folding state, the first screen body 10 and the second screen body 20 can be switched by rotating either of them around the main hinge 31, which is simple and convenient.

[0045] In the embodiment of the present application, the electronic device may also have multiple unfolding states. Specifically, the unfolding states may include: a first unfolding state and a second unfolding state; wherein, when the electronic device is in the first unfolding state, the connecting member 32 is located on the same side of the first screen body 10 and the second screen body 20, and the connecting member 32 is perpendicular to the first screen body 10 and the second screen body 20; when the electronic device is in the second unfolding state, the first screen body 10, the two connecting members 32 and the second screen body 20 are located in the same plane; the first screen body 10 and the second screen body 20 are close to or away from each other, and one end of the connecting member 32 rotates around the first screen body 10 or the second screen body 20, and the other end rotates around the main hinge 31, so that the electronic device switches between the first unfolding state and the second unfolding state.

[0046] In the embodiment of the present application, the first unfolded state may also be referred to as the screen splicing state, and the second unfolded state may also be referred to as the screen separation state or the fully unfolded state. In the fully unfolded state, the first screen body 10 and the second screen body 20 are separated, and the first screen body 10, the second screen body 20 and the connecting member 32 may all be understood to be located in the same plane (e.g. Figures 9 to 11 as shown).

[0047] In the embodiment of the present application, by rotating the first screen body 10 or the second screen body 20 around the connecting member 32 connected thereto and around the main hinge 31, the electronic device can also have multiple intermediate states between the unfolded state and the folded state. Fig.12 As shown, it can be understood that the electronic device is in the third unfolded state, and the third unfolded state can be understood as a state when the angle between the first screen body 10 and the second screen body 20 is an acute angle, a right angle, or an obtuse angle. In practical applications, by adjusting the angle between the first screen body 10 and the connecting member 32 connected thereto, and the angle between the second screen body 20 and the connecting member 32 connected thereto, the angle between the first screen body 10 and the second screen body 20 can be an acute angle, a right angle, or an obtuse angle. Fig.12 As shown, when the angle between the first screen body 10 and the second screen body 20 is an obtuse angle, the screen of one of the first screen body 10 and the second screen body 20 can be used as the current display screen, and the screen of the other can be used as an input screen such as a virtual keyboard. At this time, the hinge structure 30 can act as a bracket to facilitate the placement of the electronic device and the user's viewing of the screen content.

[0048] In the embodiment of the present application, a secondary screen 104 and a receiver (such as a receiver) may be provided on the back side (the side opposite to the screen) of either the first screen body 10 or the second screen body 20. Figure 6 As shown), the display area of ​​the secondary screen 104 is smaller than the screen area of ​​either the first screen body 10 or the second screen body 20. In this way, when the mobile phone is in the folded state, the mobile phone can be in standby or sleep state, and the secondary screen 104 is used to display information such as the clock and operator; when the mobile phone is in the folded state and there is an incoming call to be answered, the secondary screen 104 is used to display the incoming call information and the answer button. In other states, it can be used to display received push information, etc. In this way, a series of tedious operations such as using the first screen body 10 or the second screen body 20 to answer the call are avoided. It is simple to operate, saves power, and improves the battery life of the mobile phone.

[0049] like Figure 7As shown, a rear camera 102 and the like can be disposed on the other side opposite to the secondary screen 104. It can be understood that the above is only an introduction to an achievable embodiment when the electronic device is in different states. In actual applications, when the mobile phone is in the folded state, it can also have other functions, which will not be described in detail in the embodiments of this application.

[0050] like Figures 9 to 11 As shown, when the mobile phone is in the second unfolded state, the first screen body 10, the second screen body 20 and the connectors 32 on both sides of the main hinge 31 are all in the same plane. The peripheral side surfaces of the first screen body 10 and the second screen body 20 can be provided with headphone jacks, USB interfaces, sound inlets, etc. according to user needs. In the embodiment of the present application, since an integrated speaker that is a two-in-one speaker and receiver can be provided, there is no need to reserve external holes and sound cavity structures on the peripheral side surfaces of the first screen body 10 and the second screen body 20, so that more space can be reserved for the layout of the mobile phone antenna. Of course, external holes and sound cavity structures can also be reserved on the peripheral side surfaces of the first screen body 10 or the second screen body 20, and those skilled in the art can set this according to actual needs.

[0051] In the embodiment of the present application, the hinge structure 30 can not only play the role of rotatably connecting the first screen body 10 and the second screen body 20, but also play the role of supporting the mobile phone holder. The hinge structure 30 serves as a bridge connecting the first screen body 10 and the second screen body 20. Through a main hinge 31 and two connecting parts 32, the angle range between the first screen body 10 and the second screen body 20 can be adjusted by 360°. It has a simple structure, low cost and higher reliability.

[0052] like Figure 2 As shown, when the screens of the first screen body 10 and the second screen body 20 are in a spliced ​​state, the connecting parts 32 on both sides of the main hinge 31 are stacked and perpendicular to the planes where the first screen body 10 and the second screen body 20 are located. At this time, the screens of the first screen body 10 and the second screen body 20 are spliced ​​together and can be used as a large screen.

[0053] In the embodiment of the present application, when the first screen body 10 and the second screen body 20 are switched from the first unfolded state of screen splicing to the second unfolded state of screen separation, one end of the connecting member 32 connected to the first screen body 10 rotates 90° around the main body of the first screen body 10, and the other end rotates 90° around the main hinge 31; one end of the connecting member 32 connected to the second screen body 20 rotates 90° around the main body of the second screen body 20, and the other end rotates 90° around the main hinge 31. In this way, the first screen body 10, the two connecting members 32 and the second screen body 20 are arranged in sequence on the same horizontal plane.

[0054] In practical applications, since the movement is relative, the connecting member 32 rotates around the screen body (the first screen body 10 or the second screen body 20) connected thereto, which can also be understood as the screen body connected to the connecting member 32 rotating around the connecting member 32. Figure 2 The first expanded state shown switches to Figure 5 The second folding state shown can be understood as the first screen body 10 rotating 90° counterclockwise around the connecting member 32 connected thereto, and the second screen body 20 rotating 90° clockwise around the connecting member 32 connected thereto, so that a 180-degree right angle is formed between the connecting members 32 connected thereto of the first screen body 10 and the second screen body 20.

[0055] In the embodiment of the present application, the non-vertical angle between the connecting member 32 and the plane where the screen body to which it is connected is located can be understood as the angle between the connecting member 32 and the plane where the screen body to which it is connected is located can be any angle within the range of 0 to 180° (excluding 90°).

[0056] In the embodiment of the present application, since the two connecting members 32 are respectively rotatably connected to the main hinge 31, one connecting member 32 is rotatably connected to the first screen body 10, and the other connecting member 32 is rotatably connected to the second screen body 20, therefore, by respectively adjusting the angle between the first screen body 10 and the connecting member 32 connected to it, the angle between the two connecting members 32, and the angle between the second screen body 20 and the connecting member 32 connected to it, the electronic device can be freely switched between a variety of unfolded states, a variety of folded states, and a variety of states between unfolding and folding, and the state of the electronic device can be more diverse and more interesting.

[0057] Reference Fig.13 , shows a schematic diagram of the structure of the main hinge according to an embodiment of the present application. Fig.13 As shown, the main hinge 31 may specifically include: a first rotating shaft 311, and a plurality of first support rods 312 sleeved on the first rotating shaft 311; the plurality of first support rods 312 are arranged at intervals along the first rotating shaft 311, and one end of each first support rod 312 is rotatably connected to the first rotating shaft 311, and the other end is rotatably connected to the connecting member 32; the plurality of first support rods 312 are alternately arranged on the connecting members 32 on both sides of the first rotating shaft 311. In the embodiment of the present application, the first supporting rods 312 are alternately arranged on the connecting members 32 on both sides of the first rotating shaft 311, so that the first rotating shaft 311 and the connecting member 32 can be rotatably connected to the first rotating shaft 311, so that the connecting member 32 can achieve 360° rotation around the first rotating shaft 311, and the structure is simpler.

[0058] It should be noted that in order to make the support of the first support rod 312 more stable and reliable, two first support rods 312 can be respectively set at the two ends of the first rotating shaft 311, and the two first support rods 312 located at the same end are symmetrically arranged, one of the first support rods 312 is connected to the first rotating shaft 311, and the other first support rod 312 is connected to the connecting member 32.

[0059] In the embodiment of the present application, a shaft groove may be further provided on the first shaft 311, and the first support rod 312 is embedded in the shaft groove. The shaft groove serves to fix and limit the first support rod 312, and the structure is simpler.

[0060] In the embodiment of the present application, when the first screen body 10 and the second screen body 20 rotate relative to each other, the main hinge 31 can also have a damping function. Specifically, the main hinge 31 can also include: a first elastic member 313, the first elastic member 313 is sleeved on the first rotating shaft 311, and at least one first elastic member 313 is sandwiched between two adjacent first support rods 312, and the first elastic member 313 can play the role of elastic supporting force (or elastic restoring force) on the first support rods 312 at both ends thereof, so that the elastic force of the first elastic member 313 on both sides of the first support rod 312 on the first support rod 312 can achieve a damping effect when the first support rod 312 rotates along the first rotating shaft 311. In the embodiment of the present application, the first elastic member 313 can specifically be a spring, an elastic block, etc.

[0061] In practical applications, in order to make the main hinge 31 have a better damping effect, the main hinge 31 also includes: a first damping member 314; the first damping member 314 is sleeved on the first rotating shaft 311, and the first damping member 314 is sandwiched between the first support rod 312 and the first elastic member 313. In the embodiment of the present application, the damping member can be made of a plastic member or a metal member. Under the elastic force of the first elastic member 313, the damping member increases the friction between the damping member and the first support rod 312 when the first support rod 312 rotates, thereby achieving a damping function. The damping member can also prevent the first support rod 312 from rotating too flexibly, thereby affecting the splicing effect and user experience.

[0062] In the embodiment of the present application, in order to achieve the aesthetic appearance of the main hinge 31 and prevent dust and other impurities from entering between the elastic member and the first rotating shaft 311 to affect the rotation effect, the main hinge 31 may also include: a sleeve 315 sleeved outside the first elastic member 313. It should be noted that when the main hinge 31 structure 30 also includes a damping member, the sleeve 315 is sleeved outside the first elastic member 313 and the damping member at the same time to protect the first elastic member 313 and the first damping member 314 and prevent the two from being misaligned. In practical applications, in order to prevent the sleeve 315 from blocking the first support rod 312 from rotating, the number of sleeves 315 is multiple, and each sleeve 315 can also be understood as being arranged between two adjacent first support rods 312. Specifically, the sleeve 315 can be a metal sleeve 315, a plastic sleeve 315, etc. In order to improve the aesthetics of the main hinge 31, different colors and patterns can also be set on the sleeve 315, and the embodiment of the present application is not limited to this.

[0063] In some embodiments, in order to limit the first support rods 312 located at both ends of the first rotating shaft 311 to prevent the first support rods 312 from falling off the first rotating shaft 311, as shown in FIG. Fig.14 As shown, a shaft cap 3111 structure can also be provided at both ends of the first shaft 311, and the outer diameter of the shaft cap 3111 is larger than the shaft diameter of the first shaft 311, so as to limit the first support rod 312, the first elastic member 313, and the first damping member 314. Optionally, a self-locking nut can also be used as the shaft cap, and threads matching the self-locking nut can be provided at both ends of the first shaft 311, so that the structure is simpler and easier to implement. In practical applications, the shaft cap can also be implemented by other structures, which will not be described in detail in the embodiments of this application.

[0064] In the embodiment of the present application, the first support rod 312 can be directly connected to the connecting member 32, or can be connected to the connecting member 32 through an adapter. In an achievable embodiment of the present application, in order to make the connection between the first support rod 312 and the connecting member 32 simpler and more reliable, the main hinge 31 may also include: fixed shafts 316 arranged on both sides of the first rotating shaft 311; the fixed shaft 316 is parallel to the first rotating shaft 311, and the fixed shaft 316 is connected to the connecting member 32; the other end of the first support rod 312 is rotatably sleeved on the fixed shaft 316, so that one end of the first support rod 312 is rotatably connected to the first rotating shaft 311, and the other end is rotatably connected to the fixed shaft 316. By fixing the fixed shaft 316 on the connecting member 32, the connection between the main hinge 31 and the connecting member 32 can be achieved, and the first support rod 312 rotates around the first rotating shaft 311 or the fixed shaft 316, so that the connecting member 32 rotates around the first rotating shaft 311 360°. In the present application, the connection between the main hinge 31 and the connecting member 32 can be made simpler by fixing the shaft 316 .

[0065] like Fig.15 As shown, in the embodiment of the present application, in order to make the structure of the first support rod 312 simpler, the first support rod 312 may include: a support ring body 3121, and connecting parts 3122 provided at both ends of the support ring body 3121, and the connecting parts 3122 are provided with first rotating holes 3123, and the first rotating shaft 311 and the fixed shaft 316 are respectively passed through the first rotating holes 3123 on the connecting parts at both ends, so as to realize the rotatable connection between the first support rod 312 and the first rotating shaft 311 and the fixed shaft 316. In practical applications, the outer size and shape of the connecting part can be matched with the outer size and shape of the main hinge 31, so as to make the structure of the hinge structure 30 more compact and more beautiful in appearance.

[0066] In the embodiment of the present application, the connecting member 32 and the first screen body 10, and the connecting member 32 and the second screen body 20 can be directly rotatably connected, or can be rotatably connected through a hinge or other adapter. In some achievable embodiments of the present application, the hinge structure 30 may also include: a secondary hinge 33; the connecting member 32 is connected to the first screen body 10 or the second screen body 20 through the secondary hinge 33. In the embodiment of the present application, the connecting member 32 can be set in a one-to-one correspondence with the secondary hinge 33, or any one of the two connecting members 32 can be connected to its corresponding screen body through the secondary hinge 33. In this regard, those skilled in the art can set it according to actual needs.

[0067] like Fig.16As shown, the secondary hinge 33 may specifically include: a second rotating shaft 331, and a plurality of second support rods 332 sleeved on the second rotating shaft 331; the plurality of second support rods 332 are arranged at intervals along the second rotating shaft 331, and one end of each second support rod 332 is rotatably connected to the second rotating shaft 331; wherein, in the secondary hinge 33 connected to the first screen body 10, the other ends of the plurality of second support rods 332 are alternately connected between the connecting member 32 adjacent thereto and the first screen body 10; and in the secondary hinge 33 connected to the second screen body 20, the other ends of the plurality of second support rods 332 are alternately connected between the connecting member 32 adjacent thereto and the second screen body 20. In the embodiment of the present application, the connecting member 32 is rotatably connected to the first screen body 10, and the connecting member 32 is rotatably connected to the second screen body 20 through the secondary hinge 33, the structure is simple, and the connection is more stable and reliable.

[0068] like Fig.16 As shown, in the embodiment of the present application, the secondary hinge 33 may also have a damping function. The second rotating shaft 331 may be sleeved with a second elastic member 333 and / or a second damping member 334, and the damping function of the connecting member 32 during the rotation process around the second rotating shaft 331 is realized by the second elastic member 333 and the second damping member 334. It should be noted that the structure and function of the second elastic member 333 on the second rotating shaft 331 can be specifically referred to the structure and function of the first elastic member 313 on the first rotating shaft 311, which will not be repeated here. The structure between the second damping member 334 and the second rotating shaft 331, the second elastic member 333 and the second support rod 332 can refer to the settings on the first damping member 314 and the first rotating shaft 311, and their structures and functions are the same, which will not be repeated here.

[0069] It should be noted that, in the embodiment of the present application, since one end of the second support rod 332 is rotatably disposed on the second rotating shaft 331, and the other end is fixedly connected to the connecting member 32 or the first screen body 10 or the second screen body 20, the second support rod 332 can be regarded as a deformation of the first support rod 312. Specifically, Fig.17 As shown, one end of the second support rod 332 may be provided with a second rotation hole 3321 matching the second rotation shaft 331, the second rotation shaft 331 is inserted into the second rotation hole 3321, and the other end of the second support rod 332 is directly fixedly connected to the connecting member 32, the first screen body 10 or the second screen body 20. In practical applications, the other end of the second support rod 332 and the connecting member 32, the other end of the second support rod 332 and the first screen body 10, and the other end of the second support rod 332 and the second screen body 20 may be fixedly connected by screws, rivets, etc., or may be connected by injection molding, etc. In the embodiment of the present application, the second support rod 332 can be prepared by injection molding, which has a simple structure and lower cost.

[0070] It is understandable that the secondary hinge 33 may further include a sleeve 315 , and the sleeve 315 is sleeved outside the second elastic member 333 and the second damping member 334 , so as to achieve the aesthetics of the secondary hinge 33 structure 30 .

[0071] It should be noted that the ends of the second rotating shaft 331 and the fixed shaft 316 can also be provided with a rotating shaft cap structure like the ones at the two ends of the first rotating shaft 311, so as to limit the first support rod 312, the second support rod 332 and other parts through the rotating shaft caps. For this, please refer to the specific structure and principle of the rotating shaft caps at the two ends of the first rotating shaft 311, which will not be repeated here.

[0072] In an embodiment of the present application, when the first screen body 10 and the second screen body 20 are connected to their corresponding connecting parts 32 through a secondary hinge 33, in order to avoid interference between the first screen body 10 and the second screen body 20 during the splicing process, a avoidance structure can be provided on the first screen body 10, the second screen body 20 and the connecting part 32.

[0073] In some feasible embodiments, the first screen body 10 and the second screen body 20 are both provided with a first inclined surface 21 at one end connected to the connecting member 30; the connecting member 32 is provided with a second inclined surface 321 and a third inclined surface 322 at one end connected to the first screen body 10 or the second screen body 20; when the electronic device is in an unfolded state or a folded state, the second inclined surface 321 or the third inclined surface 322 cooperates with the first inclined surface 21. In the embodiment of the present application, the first inclined surface 21 can limit the second inclined surface 321 or the third inclined surface 322, so as to make the electronic device more structurally stable when in the unfolded state or the folded state.

[0074] In the embodiment of the present application, when the second inclined surface 321 or the third inclined surface 322 cooperates with the first inclined surface 21, the first screen body 10 and the second screen body 20 and their corresponding connecting members 32 can be spliced ​​at a right angle or a flat angle. Figure 2 As shown, the angle between the second inclined surface 321 and the third inclined surface 322 is a, the angle between the first inclined surface 21 and the screen 11 of the first screen body 10 is b, or the angle between the first inclined surface 21 and the screen 11 of the second screen body 20 is also angle b. In the embodiment of the present application, a+2b=180°, that is, a and 2b are complementary. Figure 2As shown, in the embodiment of the present application, an angle a of 90° and an angle b of 45° are used as an example for exemplary description. In practical applications, angle b can be any value in the range of 0 to 90° (excluding 0° and 90°). For example, angle b can be 30°, 40°, 45°, 60°, 75°, etc. It can be understood that when angle b is 30°, angle a is 120°; when angle b is 45°, angle a is 90°; when angle b is 50°, angle a is 80°; when angle b is 60°, angle a is 60°; when angle b is 75°, angle a is 30°. In practical applications, those skilled in the art can set angle a and angle b according to actual conditions, and the embodiments of the present application will not be listed one by one.

[0075] like Figure 2 As shown, when the electronic device is in the first unfolded state and the screens of the first screen body 10 and the second screen body 20 are in a spliced ​​state, the first inclined surface 21 abuts against the third inclined surface 322, one of the connecting members 32 forms a 90° angle with the first screen body 10, and the other connecting member 32 also forms a 90° angle with the second screen body 20. Fig.10 and Fig.11 As shown, when the electronic device is in the second unfolded state and the screens of the first screen body 10 and the second screen body 20 are in a separated state, the first inclined surface 21 abuts against the second inclined surface 321, and the first screen body 10 and its corresponding connecting member 32 are in the same plane, and the second screen body 20 and its corresponding connecting member 32 are also in the same plane. Of course, in actual applications, the end faces of the first screen body 10 and the second screen body 20 can also be provided with inclined surfaces of other angles, as long as the first screen body 10 and its corresponding connecting member 32 form a right angle when in the spliced ​​state, and the first screen body 10 and its corresponding connecting member 32 form a flat angle when in the fully unfolded state.

[0076] In the embodiment of the present application, the first screen body 10 and the connecting member 32 connected thereto are matched through the inclined surface, which can not only avoid the interference problem between the first screen body 10 and the connecting member 32 during the rotation process, but also enable the electronic device to be in a folded state or an unfolded state, so that the first screen body 10 and the connecting member 32 abut against each other through the inclined surface to form a limit, thereby enabling the first screen body 10 to be in a folded state or an unfolded state more accurately and stably. The above is only an exemplary description of the principle and effect between the first screen body 10 and the connecting member 32 connected thereto, and the connection between the second screen body 20 and the connecting member 32 connected thereto can refer to the first screen body 10 and its corresponding connecting member 32, which will not be repeated here.

[0077] like Fig.18As shown, the first screen body 10 and the second screen body 20 are connected through a main hinge 31, a secondary hinge 33 and a connecting member 32. One end of each connecting member 32 is connected to a main hinge 31, and the other end is connected to a secondary hinge 33. Each connecting member 32 can rotate around the first rotating shaft 311 of the main hinge 31, and can also rotate around the second rotating shaft 331 of the secondary hinge 33. In practical applications, it can be understood that the connecting member 32 rotates around the first rotating shaft 311 and the second rotating shaft 331 respectively, thereby realizing the splicing and separation between the first screen body 10 and the second screen body 20, and the structure is simple.

[0078] like Fig.19 As shown, during the splicing process of the first screen body 10 and the second screen body 20, the user can simultaneously apply a horizontal inward thrust F to the first screen body 10 and the second screen body 20. At this time, the secondary hinge 33 connecting the connecting member 32 and the screen body will be subjected to a vertical thrust F1, and then the connecting member 32 will rotate synchronously with the first rotating shaft 311 of the main hinge 31 in the direction h, and continue to apply the horizontal thrust F until the two connecting members 32 are close to each other and perpendicular to the plane where the first screen body 10 and the second screen body 20 are located (such as Figure 2 As shown), the first screen body 10 and the second screen body 20 are spliced ​​into a large screen, and the splicing of the first screen body 10 and the second screen body 20 is completed.

[0079] like Fig. 20 As shown, during the process of switching the first screen body 10 and the second screen body 20 from the folded state to the unfolded state, the user can simultaneously apply a horizontal outward pulling force F to the first screen body 10 and the second screen body 20. At this time, a horizontal pulling force F2 will be synchronously generated at the secondary hinge 33 between the screen body and the connecting member 32 connected thereto, and then the connecting member 32 can synchronously rotate in the g direction along the first rotating axis 311 of the main hinge 31; at this time, the vertical thrust f continues to be applied to make the first screen body 10 and the second screen body 20 rotate in the z direction along the second rotating axis 331 of the corresponding secondary hinge 33, respectively, until the first screen body 10 and the second screen body 20 are in the same plane, and the two connecting members 32 are perpendicular to the plane where the first screen body 10 and the second screen body 20 are located, the first screen body 10 and the second screen body 20 slowly close the screen to reach the "splicing" state, and then the screen can be achieved. Figure 1 or Figure 2 It should be noted that, when the first screen body 10 and the second screen body 20 are switched from the folded state to the unfolded state, there is no absolute order of operation for the rotation of the main hinge 31 and the rotation of the secondary hinge 33, as long as the safety regulations are met.

[0080] In the embodiment of the present application, when the mobile phone is in a folding state, that is, the screens of the first screen body 10 and the second screen body 20 are close to each other, in order to avoid hard-to-hard contact between the two screens and damage to the screen, at least one of the first screen body 10 and the second screen body 20 is provided with a buffer protrusion 34 at the side edge, and the buffer protrusion 34 faces away from the plane where the first screen body 10 or the second screen body 20 is located, and extends along the side edge. In the embodiment of the present application, since the buffer protrusion 34 can be understood as protruding from the plane where the mobile phone screen is located, when the mobile phone is folded, the buffer protrusion 34 can play a buffering role when the mobile phone is folded, and play a protective role for the first screen body 10 and the second screen body 20. Specifically, in the embodiment of the present application, the buffer protrusion 34 can be provided at the edge of the shell of the first screen body 10 or the shell of the second screen body 20. For example, the buffer protrusion 34 can be provided at the edge of the middle frame. The buffer protrusion 34 and the middle frame can be an integral structure formed by mold injection molding, or can be a rubber strip attached to the middle frame. For example Figure 8 As shown, the buffer protrusion 34 can be set on the side edge of the middle frame parallel to the main hinge 31 to play a better buffering and protective role.

[0081] In the embodiment of the present application, the electronic device being in the first unfolded state may also be referred to as the electronic device being in the extended mode. Fig.21 , shows a control flow chart of the electronic device described in the embodiment of the present application. Fig.21As shown, in step 101, after the electronic device is turned on and running, the current state of the first screen body 10 and the second screen body 20 can be first obtained, for example, whether the first screen body 10 and the second screen body 20 are in the first unfolded state or the second unfolded state. In step 102, when the first screen body 10 and the second screen body 20 are in the first unfolded state, since the screens of the first screen body 10 and the second screen body 20 are in a spliced ​​state, the screens of the first screen body 10 and the second screen body 20 are displayed as a whole to display the current running interface. For example, when the screens of the first screen body 10 and the second screen body 20 are in a spliced ​​state, it is considered that the first screen body 10 and the second screen body 20 can work together, and the screens of the first screen body 10 and the second screen body 20 are used as a display screen to display the currently running application or system interface. When the screens of the first screen body 10 and the second screen body 20 are in a separated state, different applications can be displayed on the first screen body 10 and the second screen body 20 respectively according to the preset rules. For example, when the screens of the first screen body 10 and the second screen body 20 are in a separated state, it is defaulted that the screens of the first screen body 10 and the second screen body 20 are displayed independently. At this time, the currently running application can be displayed on the first screen body 10 according to the priority of the running application, and the dormant application can be displayed on the second screen body 20; or, when there is no application currently running, the non-system application currently running in the system can be obtained, and the system main page can be displayed on the screen of the first screen body 10, and the system settings page can be displayed on the screen of the second screen body 20.

[0082] In the embodiment of the present application, when the screens of the first screen body 10 and the second screen body 20 are in a spliced ​​state, the screens of the first screen body 10 and the second screen body 20 work together as a whole display screen, which can effectively increase the area of ​​the display screen and improve the convenience of user operation; when the screens of the first screen body 10 and the second screen body 20 are in a separated state, the screens of the first screen body 10 and the second screen body 20 work independently, which can not only reduce the screen cost and damage rate of the electronic device, but also improve the functionality and fun of screen use.

[0083] It should be noted that in actual applications, multiple sensors need to be installed inside the electronic device to cooperate with different application scenarios to obtain and control the status of both the first screen body 10 and the second screen body 20, which will not be elaborated in this application.

[0084] like Figures 6 to 8As shown, when the user does not need to use a large screen, or the electronic device is in a dormant state, the electronic device can be set to a positive folding state, that is, both display screens are turned inward and are not visible to the outside. At this time, the clock, answering calls, etc. can be displayed through the secondary screen 104 on the first screen body 10 or the second screen body 20, which can not only effectively reduce power consumption, but also avoid wear and tear caused by exposure of the display screen. In the embodiment of the present application, whether the first screen body 10 and the second screen body 20 are turned inward to a positive folding state or turned outward to a reverse folding state, compared with conventional folding mobile phones, they have the advantages of thinner thickness, lighter weight, and easier for users to carry.

[0085] In actual application, since the width of the first screen body 10 and the second screen body 20 is narrow when they are in the reverse folded state, it is convenient for the user to operate with one hand. Therefore, when the user has only one display screen, it can be divided into left single-hand mode and right single-hand mode according to the user's habits. Figure 4 As shown in FIG. 1 , it can be regarded as a left-handed mode, which means holding the electronic device with the left hand. Figure 3 As shown, it can be regarded as the right single-handed mode, that is, holding the electronic device with the right hand. Specifically, light distance sensors can be respectively set on the first screen body 10 and the second screen body 20, and the state of the light distance sensors on the two screen bodies can be used to determine whether the electronic device is currently in call mode or non-call mode, and then the facial information obtained by the front camera 101 can be used to determine whether it is the left single-handed mode or the right single-handed mode, so that it can be switched between the first screen body 10 and the second screen body 20 according to the user's current holding state, so as to facilitate user operation. Moreover, in the embodiment of the present application, since the first screen body 10 and the second screen body 20 are in the reverse folding state, the existence of the hinge structure 30 is more conducive to reducing the occurrence of accidental touches of the screen in the one-handed mode. It should be noted that the above is only an exemplary description. In actual applications, other sensors can also be used to judge the current holding state, so that the user can selectively switch between the first screen body 10 and the second screen body 20. In the embodiment of the present application, single-screen one-handed operation is achieved by switching between the first screen body 10 and the second screen body 20, which not only makes the user operation simpler and more convenient, but also effectively saves screen power consumption and effectively improves the battery life of the electronic device.

[0086] In the embodiment of the present application, the hinge structure 30 can not only serve as a connecting bridge between the first screen body 10 and the second screen body 20, but also serve as a mobile phone holder to place the electronic device at a more convenient viewing angle for the user. Fig.12 As shown, when the hinge structure 30 is used as a bracket, it can not only better meet the user's viewing needs, but also make the center of gravity of the electronic device more stable compared to a conventional folding mobile phone, the angle control more flexible, and the user experience more comfortable.

[0087] In summary, the electronic device described in the embodiments of the present application has at least the following advantages:

[0088] In the embodiment of the present application, since the first screen body and the second screen body are connected by the main hinge and the connecting parts on both sides thereof, the first screen body and the second screen body can be respectively rotated along the main hinge, the first screen body and the second screen body through the connecting parts, so that the first screen body and the second screen body can be switched between a folded state and an unfolded state. Therefore, in the embodiment of the present application, the screens in the first screen body and the second screen body can both use hard screens (LCD screens or OLED screens) with lower costs than flexible screens. The large-screen function can be achieved by splicing the first screen body and the second screen body, or the first screen body and the second screen body can be separated so that the two first screen bodies and the second screen bodies can be used and work separately. In this way, not only can the screen cost and damage rate of the electronic device be reduced, but also the functionality and fun of screen use can be improved.

[0089] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
