The electronic equipment comprises a first screen and a second screen, the first screen and the second screen can rotate around a rotating shaft in the folding process, and the folding angle between the first screen and the second screen is changed correspondingly. In actual operation, the first screen can be controlled to rotate around the shaft, so that the folding angle between the first screen and the second screen is changed, and the second screen can be controlled to rotate around the shaft, so that the folding angle is changed. When the electronic device comprises more than two screens, any two adjacent screens which are rotatably connected through the rotating shaft can be used as the first screen and the second screen.
The first screen and the second screen are connected through the first connecting portion and the second connecting portion respectively, in the process that the first screen and the second screen rotate relatively, the first connecting portion and the second connecting portion can rotate relatively, the first connecting portion is provided with a notch, the direction of the notch can face the second connecting portion, a target area on the surface of the second connecting portion is exposed in the notch, and the detection device can detect the size of the first sub-area or the second sub-area in the target area through the notch.
As shown in FIG. 2, the target area (shown within the dashed box) corresponding to the notch includes a coating that is alternating black and white; the target region may also be a region as shown in fig. 3 (shown within the dashed box), including a partially black region and a partially white region. The black area may be a light absorbing area, i.e., a first sub-area, and the white area may be a light reflecting area, i.e., a second sub-area.
As shown in fig. 3, the surface area of the second connection part includes a black and white coating, and the surface area is unfolded to be rectangular corresponding to 0 ° to 180 ° of the rotation axis, that is, a folding angle range between the first screen and the second screen. The entire surface area is divided into a plurality of target areas, the coating distribution in each target area is different, and the coating distribution at different positions on the surface of the half rotating shaft corresponds to different positions of 0-180 degrees, so that the folding angle between the screens can be determined.
Specifically, the folding angle between the first screen and the second screen can be obtained by acquiring the sizes of the black area and the white area. Wherein the detection means may be a light detector for determining the size of the first sub-area or the second sub-area by emitting light to the target area and detecting the light intensity of the reflected light; the detection means may also be a camera for detecting the size of the first and second sub-areas by taking an image comprising the first and second sub-areas.

In this embodiment, the first and second sub-regions may be a light absorbing region and a light reflecting region, respectively. The light detector emits incident light towards the target area, wherein one part of the incident light is absorbed by the light absorption area, the other part of the incident light is reflected by the light reflection area, and the data processing module can determine the size of the light reflection area according to the intensity of the reflected light. In addition, the electronic apparatus may also directly set a correspondence between the intensity of the reflected light and the folding angle, so that the folding angle between the first screen and the second screen may be acquired according to the acquired intensity of the reflected light.
As shown in fig. 3, the rotating shaft is unfolded into a rectangular shape, and half of the rotating shaft is preset to be light-absorbing dark-colored image coating, and the other half is preset to be white coating which hardly absorbs light; the entire rectangular area can also be divided according to 0 ° to 180 ° into a corresponding plurality of target areas, each of which specifies a coating of a certain absorption ratio. The ratio of absorbed to reflected light is different for each target area.
As shown in fig. 4, the coatings added to the shaft in two different ways are shown within the dashed rectangle. The whole coating surface can be superposed with a light-transmitting protective layer to cover the surface of the rotating shaft. The area corresponding to 0 to 180 degrees can be divided into n small rectangular areas, namely n target areas, wherein the n target areas comprise light absorption coatings with different light absorption ratios, so that different positions of the rotating shaft correspond to the coatings with different light absorption ratios and also correspond to different folding angles, and n is a positive integer.
When n is constant, the angle corresponding to each small rectangular region is 180/n, the angle can be customized and divided into a storage table in advance, n can be determined according to the light detection sensor and the actual angle detection precision requirement, and if n is 180, the angle corresponding to each small rectangular region is 1 degree.
The light detector is used for inputting light with certain intensity and detecting the intensity of the reflected light, and the intensity of the light absorbed by each small rectangular area is changed linearly. The folding angle between the first screen and the second screen may be determined according to a preset correspondence between the light intensity and the angle, and the intensity of the reflected light. In addition, the corresponding relation between the proportion of the light absorption area occupying the target area and the folding angle can be preset, and the folding angle value can be obtained according to the obtained reflected light intensity and the emitted light intensity.
The detection device can further comprise a data processing module, and the data processing module acquires the folding angle between the first screen and the second screen according to the preset corresponding relation between the light intensity and the angle and the intensity of the reflected light.

In this embodiment, the outer shaft is provided with a through slot, and the target area in the outer surface area of the inner shaft is exposed within the through slot. Light emitted by the light detector is emitted to the target area through the through groove and is reflected by the light reflecting area, and the light detector detects the intensity of the reflected light.
The outer surface area of the inner shaft includes a plurality of target areas, each having a different ratio of light reflecting areas to light absorbing areas. When the inner shaft and the outer shaft rotate relatively, a plurality of target areas in the outer surface area of the inner shaft are exposed in the through grooves in sequence, the light detector can detect the proportion of the light reflecting area and the light absorbing area in different target areas in sequence through the through grooves, and the folding angle between the first screen and the second screen can be obtained. Because the angle between the proportion and the screen is a preset corresponding relation, or the intensity of the reflected light and the angle of the screen are a preset corresponding relation, the folding angle obtained according to any corresponding relation is high in accuracy.
Alternatively, as shown in fig. 5, the first connecting portion 31 is an inner shaft, and the second connecting portion 32 is an outer shaft;

In this embodiment, a target area in an inner surface area of the outer shaft is exposed into the slot, and light emitted by the light detector emits light through one side of the slot and through the slot to the target area.
The inner surface area of the outer shaft includes a plurality of target areas that are sequentially exposed within the slots upon relative rotation of the outer shaft and the inner shaft. The light emitted from the light detector is emitted to the target area through the notch, and the light can be reflected by the light reflecting area, so that the intensity of the reflected light can be acquired. The data processing module 42 may determine the folding angle between the first screen and the second screen according to the intensity of the reflected light and a preset correspondence between the light intensity and the screen angle.
Because the intensity of the reflected light and the screen angle are in a preset corresponding relation, the folding angle obtained according to any corresponding relation is high in accuracy.

wherein the size of the surface area corresponds to a range of folding angles between the first screen and the second screen, and the size of each of the first sub-areas or each of the second sub-areas corresponds to a one-to-one correspondence to a folding angle between the first screen and the second screen.
As shown in fig. 3, the surface area of the second connecting portion provided with the coating is a rectangular area, the surface area can be divided into a plurality of target areas, the size of each target area can be the same, and the proportion of the first sub-area to the second sub-area in each target area is different. When the first connecting part and the second connecting part rotate to the target position, the target area corresponding to the notch can be determined according to the position, and the size of the first sub-area and the size of the second sub-area in the target area are obtained, so that the folding angle between the first screen and the second screen corresponding to the area size is determined.
