Referring to fig. 3 and 7, the supporting mechanism 13 further includes a first supporting body 134 and a second supporting body 136. The telescoping mechanism 130 is connected between the first support 134 and the second support 136. Specifically, the first supporting body 134 and the second supporting body 136 are spaced apart from each other to form a receiving space 138. The telescopic mechanism 130 is disposed in the receiving space 138. One end of the flexible band 11 is connected to the first support 134, and the other end is connected to the second support 136.

The supporting mechanism 13 further includes an elastic element 139 disposed in the second supporting body 136, and the other end of the flexible belt 11 is fixed to the elastic element 139. In this embodiment, the elastic element 139 is an elastic winding shaft. The elastic winding shaft is composed of a rotating shaft and coil springs fixed at two opposite ends of the rotating shaft. The coil spring may be resilient so that the rotatable shaft has a tendency to automatically gyrate when rotated.

The other end of the flexible belt 11 passes through the telescopic mechanism 130, extends into the second supporting body 136 and is fixed on the elastic element 139. The flexible band 11 moves following the telescopic movement of the telescopic mechanism 130. During the stretching of the telescopic mechanism 130, the elastic member 139 gradually releases the portion of the flexible band 11 wound around the elastic member 139 to allow the telescopic mechanism 130 to be stretched without being held by the elastic member 139. During the compression of the retracting mechanism 130, the portion of the flexible belt 11 released by the retracting mechanism 130 due to the contraction is timely wound and retracted by the elastic element 139. Through timely releasing or winding the flexible belt 11 by the elastic element 139, the flexible belt 11 threaded on the telescopic mechanism 130 is always in a tight state, and thus the flexible belt 11 can well support the flexible screen 20 on the flexible belt 11. A rotatable roller is provided directly above the elastic member 139 for changing the extending direction of the flexible belt 11 so that the flexible belt 11 can be fixed to the elastic member 139. It will be appreciated that the elastic element 139 may be replaced by a spring, i.e. one end of the spring is fixed to the end of the flexible band 11 extending into the second support 136, and the other end is fixed to the second support 136, e.g. the top of the back plate 1363 of the second support 136.

More specifically, the first supporting body 134 and the second supporting body 136 are similar in structure and each have a hollow box shape with one open end. Referring also to fig. 4, the opening 1340 of the first supporting body 134 and the opening 1360 of the second supporting body 136 are disposed opposite to each other. The resilient element 139 is disposed within the opening 1360 of the second support 136. In addition, the first supporting body 134 and the second supporting body 136 are configured to accommodate electronic components therein, which is not described herein again.

The first pivot portion 1344 includes two opposite pivot holes 1345 and a receiving slot 1346. The two pivot holes 1345 are disposed at two sides of the receiving slot 1346. The two pivot holes 1345 are respectively communicated with the receiving slots 1346. The first supporting body 134 further includes a first through slot 1347 disposed on a side of the first supporting plate 1341 away from the opening 1340. The first through groove 1347 is formed to penetrate the first support plate 1341 and then communicate with the inside of the first support 134. The first through groove 1347 is parallel to the first pivot portion 1344.

Further specifically, the second support 136 is similar in structure to the first support 134. The second support 136 includes a second support plate 1361 and a back plate 1363 disposed opposite to each other. The second support 136 includes a second pivot 1364 disposed in the second support plate 1361 proximate to the opening 1360. The second pivot portion 1364 includes two opposite pivot holes 1365 and a receiving slot 1366. The two pivoting holes 1365 are disposed at two sides of the receiving slot 1366. The two pivoting holes 1365 are respectively communicated with the accommodating groove 1366. The second support 136 also includes a second through slot 1367 disposed in the second support plate 1361 distal from the opening 1360. The second through groove 1367 penetrates the second support plate 1361 and is communicated with the inside of the second support 136. The second through groove 1367 is disposed in parallel with the second pivot portion 1364. The elastic member 139 is disposed in the second supporter 136 and fixed. Specifically, the elastic element 139 is disposed in the second supporting body 136 and fixed above the back plate 1363, such as being inserted into a side plate of the second supporting body 136, and the position of the elastic element 139 is opposite to the position of the second through-slot 1367.

When the telescopic mechanism 130 is located in the accommodating space 138, one end of the telescopic mechanism 130 is pivotally connected to the first supporting body 134, and the other end is pivotally connected to the second supporting body 136. Specifically, one end of the telescopic mechanism 130 is pivotally connected to the first pivot portion 1344 of the first supporting body 134, and the other end is pivotally connected to the second pivot portion 1364 of the second supporting body 136. After passing through the telescopic mechanism 130, the flexible band 11 is fixed at one end to the first support 134, preferably, fixed in the first support 134 after passing through the first through-hole 1347 of the first support 134, and fixed at the other end in the second support 136 by the elastic member 139 after passing through the second through-hole 1367 of the second support 136.

One end of the flexible screen 20 penetrates through the first through slot 1347 of the first support 134 and is fixed inside the first support 134, and the other end of the flexible screen 20 penetrates through the second through slot 1367 of the second support 136 and is fixed inside the second support 136. The second support 136 may be provided with a reel therein for winding up the flexible screen 20.

The through shaft 132 is further disposed between the first support 134 and the telescoping mechanism 131, or between the second support 136 and the telescoping mechanism 131.

Referring to fig. 8, during the stretching of the telescopic mechanism 130, the included angle a between each pair of connecting rods 133 is increased, so that the telescopic mechanism 130 becomes more flat, and therefore, a longer flexible band 11 is required to be threaded on a plurality of telescopic mechanisms 130, and the elastic element 139 gradually releases a part of the flexible band 11 wound on the elastic element 139 to allow the telescopic mechanism 130 to become more flat without being held by the elastic element 139. Referring to fig. 8, in the process of compressing the telescopic mechanism 130, the included angle a between each pair of connecting rods 133 is decreased, so that the telescopic mechanism 130 becomes thinner, and therefore, a shorter flexible belt 11 is required to be inserted into a plurality of telescopic mechanisms 130, and a portion of the flexible belt 11 released by the telescopic mechanism 130 due to contraction is timely wound and retracted by the elastic element 139. Through timely releasing or winding the flexible belt 11 by the elastic element 139, the flexible belt 11 penetrating through the plurality of telescopic mechanisms 130 is always in a tight state, and thus the flexible belt 11 can well support the flexible screen 20 on the flexible belt 11.

It will be appreciated that the flexible strap 11 may also cover the upper connecting shaft 131 directly without penetrating into the slot 1313, and may also serve as a better support. In this case, the through shaft 133 located at the third pivot hole 1373 can be omitted.

It should be understood that the telescopic mechanism 130 is not limited to the above-mentioned form of the connecting rod 133 cooperating with the connecting shaft 131, but may also include other forms of telescopic mechanisms, such as a slide-rail type drawing structure, an accordion type folding structure, etc., which are all applicable to the present application.

It should be understood that the support mechanism 13 is not limited to the telescopic mechanism 130, and may be a fixed form structure, a bendable form structure, a foldable form structure, or the like, and may be applied to the present application.

It will also be appreciated that instead of using a spring or elastic member 139 such as an elastic take-up reel to maintain the tension in the flexible band 11, a flexible band may be used which is inherently elastic, i.e. the elastic flexible band remains tensioned after stretching, thus eliminating the need for the use of an elastic member. Since the flexible band 11 is used as a member for supporting the flexible screen 20, it can provide a better support for the flexible screen 20 as long as it can maintain a tensioned state.

The utility model provides a supporting component and electronic equipment through the flexible band of tensioning for the bottom of flexible screen has sufficient effective support area, thereby also can obtain good support after the flexible screen is tensile, has increased the life of equipment.

The foregoing is a preferred embodiment of the present application and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present application, and such improvements and modifications are also considered as the scope of the present application.
