In this embodiment, the adjusting member 257 includes an adjusting screw 2572 and an elastic member 2574, the adjusting screw 2572 can connect the connecting member 254 and the positioning member 255, and the elastic member 2574 elastically abuts between the connecting member 254 and the positioning member 255. Specifically, the elastic member 2574 is a spring.

As shown in fig. 3, the flexible screen 30 includes a flexible screen body 35 and a supporting sheet 36 attached to the back of the flexible screen body 35, and the supporting sheet 36 covers the bendable region 31 of the flexible screen 30. The support sheet 36 may be a thin metal sheet such as copper foil, liquid metal sheet, memory alloy sheet, plastic sheet or other suitable material. In this embodiment, the support sheet 36 is a liquid metal sheet.

The term liquid metal in this application refers to an alloy which is heated to a molten state and then cooled at an ultra-fast cooling rate to solidify the alloy crystal lattice as it is not in a well-ordered arrangement, and is also referred to as an amorphous alloy, liquid metal or metallic glass because it is in an amorphous state like glass. The liquid metal has the characteristics of long-range disorder (short-range order), metastable state, certain physical property isotropy, no definite melting point, glass transition temperature point and the like, has the characteristics of solid state, metal and glass, and can have high strength, high hardness, plasticity, heat conduction, wear resistance and the like under certain conditions. That is, the liquid metal referred to in the present invention is substantially solid at normal temperature, but has some properties close to those of liquid, and is therefore referred to as liquid metal. The liquid metal can be an alloy material of one or more materials of copper, titanium, iron, zirconium, silver, nickel, gallium, gold, antimony, cadmium, zinc, indium, silicon and the like, and the specific metal preferably can obtain other mechanical properties such as lower elastic modulus, hardness, extensibility and the like.

The reason why the liquid metal sheet is selected as the support sheet 36 in this embodiment is that the liquid metal sheet has better wear resistance. On one hand, the supporting piece 36 can effectively resist the friction generated by the hinge device 25, and is not easy to wear; on the other hand, the liquid metal sheet has a low elastic modulus, and when the electronic device 100 is bent by the hinge device 25, the supporting sheet 36 can be stretched synchronously or approximately synchronously with the flexible screen, so that the flexible screen is prevented from being damaged due to a large difference in stretching amplitude when being bent. The liquid metal can be copper-based, titanium-based, iron-based, zirconium-based, silver-based, nickel-based, gallium-based, gold-based, antimony-based, cadmium-based, zinc-based, indium-based, silicon-based and other liquid metals, and compared with the existing materials with lower elastic modulus, such as silica gel, foam, plastic and the like, the liquid metal has higher strength and better wear resistance, and can effectively support the flexible screen.

The support sheet 36 has a modulus of elasticity greater than that of the flexible screen (the modulus of elasticity of the flexible screen is the average modulus of elasticity of the film layers). Because the elastic modulus of each membrane material (such as luminescent layer, stratum basale, cathode layer, anode layer, TFT layer etc.) of flexible screen all is in lower scope, if adopt commonly used sheetmetal, material such as steel sheet, aluminum plate is fixed as the direct and flexible screen laminating of protective layer, then because the elastic modulus of common sheetmetal is far greater than the elastic modulus of each membrane material of flexible screen, will be easily because the tensile volume difference is too big and lead to the condition that flexible screen 35 damaged when buckling together with flexible screen 35. Therefore, the present invention uses the liquid metal with the elastic modulus more closely matched with the flexible screen body 35 as the protection sheet, and compared with the common metal sheet, the present invention has the elastic modulus more closely matched with the flexible screen body 35, and can provide sufficient hardness to support the flexible screen body 35, so the present invention is an ideal material.

Referring to fig. 2 to 8, when the housing 20 of the electronic device 100 is assembled, the first connecting portion 212 of the first frame 21 is connected to the first mounting portion 2510 of the hinge main body 251, so that the positioning block 2513 of each connecting strip 2511 is clamped in the corresponding positioning hole 214, each connecting piece 2512 is attached to the corresponding connecting block 216, and the plurality of locking members pass through the connecting holes of the connecting piece 2512 and are locked in the corresponding connecting holes 2162. Each connecting mechanism 252 is assembled by passing the adjusting screw 2572 through the positioning member 255 and connecting to the connecting member 254, and specifically, the adjusting screw 2572 is threaded into the screw hole 2542 of the connecting piece 2541 after passing through the through hole 2556 of the connecting piece 2553 and the elastic member 2574. At this time, the elastic member 2574 is sleeved on the adjusting screw 2572, one end of the elastic member 2574 is accommodated in the accommodating groove 2554, and the elastic member 2574 is elastically clamped between the connecting member 254 and the positioning member 255. The connecting members 254 of the two connecting mechanisms 252 are inserted into the mounting grooves 2517 of the two connecting frames 2515, respectively, such that each connecting rack is engaged with the gear in the corresponding mounting groove 2517, and the pair of guide bars 2546 of the connecting members 254 are slidably received in the pair of guide grooves 2518 of the connecting frames 2515. The second connecting portion 232 of the second frame 23 is connected to the second mounting portion 2514 of the hinge body 251, and it is checked whether the positioning block 2551 of the positioning element 255 of each connecting mechanism 252 is aligned with the corresponding fixing hole 234 of the second frame 23, that is, whether the positioning block 2551 is directly clamped in the fixing hole 234. If the positioning block 2551 is just opposite to the corresponding fixing hole 234, the positioning block 2551 is directly clamped in the fixing hole 234; if the positioning block 2551 is not aligned with the corresponding fixing hole 234, that is, since the tolerance of the overall length of the hinge body 251 is relatively large, the positioning block 2551 is offset from the corresponding fixing hole 234. By adjusting the adjusting screw 2572 of the connecting mechanism 252, the positioning block 2551 moves relative to the connecting member 254, that is, the relative distance between the positioning member 255 and the connecting member 254 changes, and the elastic member 2574 elastically abuts between the positioning member 255 and the connecting member 254 until the positioning block 2551 directly faces the fixing hole 234. The positioning block 2551 of each positioning element 255 is clamped in the corresponding fixing hole 234, and the guide plate 2544 of the connecting element 254 is slidably received in the receiving groove 235. Each connecting piece 2516 is attached to the corresponding connecting block 236, and a plurality of locking pieces pass through the connecting holes of the connecting pieces 2516 and are locked in the corresponding connecting holes 2362. Of course, the connection mechanism may be fixed to the second housing, the second mounting portion 2514 of the hinge body 251 may be fixed to the second connecting portion 232 of the second frame 23, the connecting piece 2516 of the hinge body 251 may be fixed to the connecting block 236, and then the distance between the positioning piece 255 and the connecting piece 254 may be adjusted so that the rack on the connecting piece 254 is aligned with and abutted to the gear in the mounting groove 2517 of the hinge body 251, thereby achieving the overall mounting.

Further, the distance between the positioning member 255 and the connecting member can be finely adjusted by screwing a screw so that a specific tooth on the rack of the connecting member 254 is aligned with and engaged with the gear of the hinge body 251 for the purpose of precise fitting. Since the tolerance stack-up of the hinge body 251 is not so large, generally in the range of 1 to several teeth in width, only the fine adjustment of the connection mechanism is required to adjust to the corresponding teeth, so that the tolerance stack-up of the overall length of the hinge device 25 in the direction perpendicular to the bending axis of the hinge body 251 can be compensated for to facilitate the mounting of the hinge device 25 to the housing 20.

The flexible screen 30 is mounted on the housing 20, specifically, the bendable region 31 of the flexible screen 30 is attached to the front surface of the hinge device 25, and the two non-bendable regions 33 of the flexible screen 30 are respectively connected to the front surfaces of the first frame 21 and the second frame 23. The housing 20 is bent or unfolded by the hinge device 25, and the flexible screen 30 is bent or unfolded along the bendable region 31 with the hinge device 25.

In other embodiments, the connecting mechanism 252 may be installed between the first frame body 21 and the hinge body 251, that is, a fixing hole is opened at a side of the first frame body 21 adjacent to the hinge body 251, the connecting mechanism 252 is disposed at a side of the hinge body 251 adjacent to the first frame body 21, and the positioning block 2551 of the connecting mechanism 252 is clamped in the fixing hole.

In other embodiments, the first frame 21 and the hinge body 251 and the second frame 23 and the hinge body 251 are connected by a connection mechanism 252.

In the assembled state, if the positioning block 2551 is not aligned with the corresponding fixing hole 234, the positioning block 2551 is offset from the corresponding fixing hole 234. By loosening the locking screw 2576, the pressing of the locking screw 2576 to the adjusting strip 2575 is released, the positioning piece 255 is moved to enable the adjusting strip 2575 to move in the through hole 2547, that is, the relative distance between the positioning piece 255 and the connecting piece 254 is changed until the positioning piece 2551 is right aligned with the fixing hole 234, and then the locking screw 2576 is tightened to press and fix the adjusting strip 2575. At this time, the positioning blocks 2551 can be clamped in the corresponding fixing holes 234.

The connection mechanism 252a of this embodiment can adjust the distance between the connection member 254 and the positioning member 255 by loosening the locking screw 2576 and sliding the positioning member 255 to move the adjustment bar 2575 in the through hole 2547, so as to compensate for the tolerance stack-up of the overall length of the hinge body 251.

It is to be understood that the term "relative sliding" in the present invention does not limit the direct contact and relative sliding between two elements, but may also include the relative sliding of a third-party element, and the third-party element is not limited to a solid element, such as a sheet, a film, etc., but may also include a non-solid element, such as a gap, a space, etc., or a combination of a solid element and a non-solid element; the third party element is also not limited to one, but may include a plurality. That is, as long as two elements have a relative sliding kinematic relationship, regardless of the actual positions of the two elements, they can be considered to be within the scope of what is referred to herein as "relative sliding".

It should be noted that, in the above embodiments, when bending, the opposite ends of the hinge body actively drive the first frame body and the second frame body to move toward the hinge body, so as to compensate the problem of the radius difference caused by bending, and prevent the flexible screen from being stretched. The hinge with the structure drives the first frame body and the second frame body to move by converting relative rotation between the chains of the hinge into translation through the gear, and the active compensation mode is adopted, so that more parts are needed, the problem of larger tolerance caused by poor control is easy to generate during assembly, and the hinge cannot be accurately fixed to the corresponding position of the shell. Therefore, a connection mechanism is required to compensate for the tolerance. For the passive compensation mode, that is, the first frame and the second frame are pulled by the flexible screen to compensate the radius difference, but not the situation that the first frame and the second frame are actively driven by the hinge to move, because the elastic members are usually arranged between the first frame and the hinge and between the second frame and the hinge to keep the first frame and the second frame moving relative to the hinge, the elastic members themselves have the function of compensating for a certain tolerance, and therefore, an additional connecting mechanism is not required to be arranged to compensate for the tolerance in general. However, the present invention does not exclude the case where the connection mechanism is provided on the passive compensation hinge. In addition, when a virtual axis type hinge is used, the centers of the mutual rotation of the hinges are located on the flexible screen, and the assembly of the hinge also has tolerance problems, so that a connecting mechanism is also required to compensate the tolerance.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
