For example, the display 30 may be a folded-in display, specifically, the display 30 has a display surface 38, when the display 30 is in a flat state, as shown in fig. 1, the display surface 38 of the display 30 is disposed flatly, and the display surface 38 may display a picture, as shown in fig. 2, when the display 30 is in a folded state, the display surface 38 is located inside the display 30, and the display 30 is in a curved shape, it can be understood that the display 30 is better protected by adopting the folded-in mode shown in fig. 1 and 2. Of course, the present application is not limited thereto, and the display 30 may be folded outwards.

It should be noted that, in practical research, the inventor finds that, particularly, in an electronic device of a pin-in-pin folding type, when the electronic device is switched between a folding state and an unfolding state, the relative length of the display screen and the housing changes, but the display screen cannot be stretched, which requires designing a stretching mode of the housing.

According to the electronic device 1 of the embodiment of the present application, at least two adjacent connecting members 12 can move relatively to adjust the length of the telescopic mechanism 10 along the arrangement direction of the plurality of connecting members 12, so that in the process of folding the first plane portion 32 relative to the second plane portion 36, the telescopic mechanism 10 can extend to flexibly support the bendable portion 34, which is beneficial to reducing contact stress, thereby being beneficial to reducing the generation of creases, ensuring the working reliability of the display screen 30, and prolonging the service life of the electronic device 1.

It will be appreciated that the greater the number of links 12, the more rounded the bend line of the mechanism 10 after bending. However, the greater the number of links 12, the more complex the mechanism 10 and the higher the cost of manufacture, and the higher the maintenance costs due to the fact that damage to one of the parts affects the use of the entire mechanism 10.

In order to maintain a good bending effect and simplify the structure of the telescopic mechanism 10, in the telescopic mechanism 10 of the present application, the number of the connecting members 12 may be three, four, five, six, seven or eight, etc.

Referring to fig. 3, two adjacent connecting members 12 form a group of connecting member groups, the telescopic mechanism 10 includes rotating shafts 14 (see fig. 2), the number of the rotating shafts 14 is the same as that of the connecting member groups, one of the connecting members 12 in the group of connecting members is provided with a first pivot hole 1222 and the other is provided with a second pivot hole 1242, one end of the rotating shaft 14 is immovably inserted into the first pivot hole 1222, and the other end of the rotating shaft 14 is movably inserted into the second pivot hole 1242. The rotating shaft 14 may be a pin. Therefore, the rotatable and movable connection between the two connecting pieces 12 in one group of connecting piece groups is convenient to realize, and the structure is simple and the connection is reliable.

For example, referring to fig. 3 and 4, the first connecting element 12a and the third connecting element 12b form a group of connecting elements, the first connecting element 12a and the third connecting element 12b are connected by a pin, the third connecting element 12b is provided with a first pivot hole 1222, the first connecting element 12a is provided with a second pivot hole 1242 aligned with the first pivot hole 1222, the diameter of the pin is the same as that of the first pivot hole 1222, one end of the pin is inserted into the first pivot hole 1222, and the other end of the pin is rotatably and movably inserted into the second pivot hole 1242.

Referring to fig. 3, the first pivot hole 1222 is formed as a circular hole, and the second pivot hole 1242 is formed as an oblong hole. Therefore, the two connecting pieces 12 in one group of connecting piece groups can be matched reliably, the structure is simple, and the processing and forming of the connecting pieces 12 are facilitated.

Further, referring to fig. 3 and 6, any two adjacent connecting members 12 can move relatively, and each connecting member 12 is provided with a first pivot hole 1222 and a second pivot hole 1242. This is advantageous in that the telescopic capability of the telescopic mechanism 10 is improved, the contact stress is reduced, and the effect of the telescopic mechanism 10 in flexibly supporting the bendable portion 34 is improved.

Referring to fig. 6, 7 and 8, each of the connectors 12 is identical in size and shape. Therefore, the telescopic mechanism 10 is simple in structure, convenient to assemble and maintain and beneficial to reducing production and maintenance cost.

As shown in fig. 4 and 5, the connecting member 12 is a metal member. For example, the connector 12 may be a stainless steel piece. This is advantageous in improving the corrosion resistance of the telescopic mechanism 10 and prolonging the service life of the telescopic mechanism 10.

Referring to fig. 1 and 2, the first link 12a is rotatably coupled to the first housing 50, and the second link 12c is rotatably coupled to the second housing 70. For example, the first connecting member 12a is rotatably connected to the first housing 50 by a pin, and the second connecting member 12c is rotatably connected to the second housing 70 by a pin. It can be appreciated that by having the first connector 12a rotatably connected to the first housing 50 and the second connector 12c rotatably connected to the second housing 70, the foldable angle of the electronic device 1 is increased, and the first plane portion 32 is conveniently switched between the folded 180 degrees and the unfolded state with respect to the second plane portion 36. Of course, the application is not limited thereto, and the first connecting member 12a may be non-rotatably connected with the first housing 50, for example, the first connecting member 12a is fixedly connected or detachably connected with the first housing 50; the second connecting member 12c may also be non-rotatably connected to the second housing 70, for example, the second connecting member 12c may be fixedly connected to or detachably connected to the second housing 70.

Referring to fig. 9, each of the connection members 12 includes a main body portion 124 and a protrusion portion 122, the main body portion 124 and the protrusion portion 122 are arranged in an arrangement direction of the plurality of connection members 12, a fitting groove 126 is provided on the main body portion 124, a side of the fitting groove 126 adjacent to the foldable portion 34 is opened to form a first opening 1262, a side of the fitting groove 126 facing the connection member 12 adjacent to the fitting groove 126 is opened to form a second opening 1264, the first opening 1262 communicates with the second opening 1264, a first pivot hole 1222 is formed on the protrusion portion 122 and penetrates through the protrusion portion 122, and a second pivot hole 1242 is provided at the fitting groove 126 and penetrates through the main body portion 124.

It can be understood that the protruding portion 122 can rotate around the central axis of the rotating shaft 14 in the corresponding matching groove 126, and the matching groove 126 can limit the rotation of the protruding portion 122, so that the connecting members 12 can rotate around the corresponding rotating shaft 14 at a certain angle, which is beneficial to limiting the rotation angle between two adjacent connecting members 12, thereby being beneficial to preventing the folding R angle of the display screen 30 from being too small in the bending process, and further overcoming the problem of the crease caused by the over-folding of the display screen 30.

As shown in fig. 9 and 10, the fitting groove 126 has a first side wall 1266 and a second side wall 1268 adjacent to each other, the first side wall 1266 is provided opposite to the first opening 1262, the second side wall 1268 is provided opposite to the second opening 1264, the protrusion 122 abuts against the first side wall 1266 of the fitting groove 126 fitted to the protrusion 122 in the folded state, and the protrusion 122 abuts against the second side wall 1268 of the fitting groove 126 fitted to the protrusion 122 in the unfolded state. Alternatively, in the folded state, the folding angle of the entire telescopic mechanism 10 may take any one of 80 degrees to 100 degrees.

For example, as shown in fig. 1, when the display screen 30 is flattened (i.e., the bending portion 34 is flattened), the first connecting member 12a, the third connecting member 12b and the second connecting member 12c are parallel to each other, the rotating shaft 14 moves to the middle of the second pivot hole 1242 engaged with the rotating shaft 14, the protrusion 122 abuts against the second side wall 1268 of the engaging groove 126 engaged with the protrusion 122 to perform a limiting function, and the length of the entire telescopic mechanism 10 is shortest at this time.

As shown in fig. 2, when the display screen 30 is folded by 180 degrees, the first connecting member 12a, the third connecting member 12b and the second connecting member 12c are rotated by a certain angle to make the telescopic mechanism 10 reach a folded position (for example, as shown in fig. 2, the whole telescopic mechanism 10 is folded by 90 degrees), at this time, the protrusion 122 abuts against the first side wall 1266 of the matching groove 126 matched with the protrusion 122 to perform a limiting function, and the length of the whole telescopic mechanism 10 is longest at this time.

From this, be favorable to preventing the folding R angle undersize at the in-process display screen 30 of buckling, and then overcome the problem that produces the crease because of display screen 30 is overfold, simultaneously, fold condition and can all realize spacing to every connecting piece 12 with unfolding the state, telescopic machanism 10 can realize the reliable support to bendable portion 34, is favorable to improving the reliability that electronic equipment switched between flat state of exhibition and folding 180 degrees states, guarantees that display screen 30 is not destroyed.
