Specifically, when the first angle and the second angle are equal and equal to the predetermined angle α, a formula is adopted

Referring to fig. 5, the distance between the first sub-ranging unit 410 and the rotating shaft 300 is the first distance d1, and the distance between the second sub-ranging unit 420 and the rotating shaft 300Is a second distance d2, and the first distance d1 is equal to the second distance d2, the processor 200 obtains a first sub-ranging distance c1 between the first sub-ranging unit 410 and the position where the first sub-ranging signal reaches the second fold 120 according to the first sub-ranging unit 410, obtains a second sub-ranging distance c2 between the second sub-ranging unit 420 and the position where the second sub-ranging signal reaches the second fold 120 according to the second sub-ranging unit 420, takes an average value of the first sub-ranging distance c1 and the second sub-ranging distance c2 as the detection distance c, and calculates a folding angle between the first fold 110 and the second fold 120 according to the detection distance c
Figure BDA0001937788280000072
The first sub-ranging unit 410 and the second sub-ranging unit 420 may be the same ranging unit 400 or different ranging units 400.

In the above embodiment, when the first distance d1 between the first sub ranging unit 410 and the rotation shaft 300 and the second distance d2 between the second sub ranging unit 420 and the rotation shaft 300 are equal, the first sub ranging unit 410 and the second sub ranging unit 420 are located at the edge region of the first folding part 110 and are symmetrically disposed about the plane orthogonal to the rotation shaft 300, which bisects the first folding part 110. That is, the first sub ranging unit 410 and the second sub ranging unit 420 are symmetrical with respect to one plane of the electronic device 10.
Further, when the first angle between the first sub-probe signal and the first folding portion 110 and the second sub-probe signal and the first folding portion 110When the second angle between the first folding portions 110 is equal, on one hand, the same calculation formula can be adopted to calculate the distance parameter c, and on the other hand, the first sub ranging unit 410 and the second sub ranging unit 420 are arranged to be matched with each other, so that the precision of measuring the distance parameter c can be improved, and then the accurate folding angle can be obtained according to the ranging parameter c
Figure BDA0001937788280000074
Thus, the measurement of the folding angle can be improved while improving the data processing efficiency
Figure BDA0001937788280000075
And by mutual rectification of the first sub-ranging unit 410 and the second sub-ranging unit 420, the error of the measurement may be reduced. At this time, an average value of the first sub-ranging distance c measured by the first sub-ranging unit 410 and the second sub-ranging distance c measured by the second sub-ranging unit 420 is taken as the detection distance c, and the folding angle between the first folding part 110 and the second folding part 120 is calculated according to the detection distance c
Figure BDA0001937788280000076
In this embodiment, since the first angle is equal to the second angle and the first distance d1 is equal to the second distance d2, the possibility of mutual interference between the first sub-probe signal and the second sub-probe signal is high, and thus the first sub-probe distance c1 and the second sub-probe distance c2 are considered to be acquired with errors, and therefore, the first sub-probe distance c1 and the second sub-probe distance c2 need to be processed first to avoid generating accumulated errors, which results in the finally acquired folding angle

With a large error. Then, an average value of the first sub probe distance c1 and the second sub probe distance c2 is calculated, and the average value of the first sub probe distance c1 and the second sub probe distance c2 is used as the probe distancec, and calculating a folding angle between the first folding part 110 and the second folding part 120 according to the detected distance c

Referring to fig. 9, the second folding portion 120 is provided with a correction distance measuring unit 500, a distance from the correction distance measuring unit 500 to the rotating shaft 300 is consistent with a distance from the distance measuring unit 400 to the rotating shaft 300, the correction distance measuring unit 500 transmits a correction signal towards the first folding portion 110 at a preset angle α to obtain a correction distance between the correction distance measuring unit 500 and a position where the correction signal reaches the first folding portion 110, and the processor 200 corrects the detection distance c according to the correction distance, wherein a direction of the correction signal is orthogonal to the rotating shaft 300.
The correcting and ranging unit 500 is configured to correct the distance parameter measured by the ranging unit 400, and the correcting and ranging unit 500 is configured to refer to the distance parameter measured by the ranging unit 400.
The distance measurement precision of the distance measurement unit 400 is a first precision, the distance measurement precision of the correction distance measurement unit 500 is a second precision, and the first precision is greater than the second precision, that is, the value corresponding to the first precision is smaller than the value corresponding to the second precision. That is, the distance measuring unit 400 adopts relatively high measuring precision, the correcting distance measuring unit 500 adopts relatively low measuring precision, the cost can be saved, the measuring parameters of the distance measuring unit 400 are corrected through the correcting distance measuring unit 500, and more accurate folding angle can be obtained
Figure BDA0001937788280000121
Is measured.
When the difference between the distance c obtained by the distance measuring unit 400 with the first precision and the distance c obtained by the distance measuring unit 400 with the position where the detection signal reaches the second folding part 120 and the distance c obtained by the distance measuring unit 400 with the second precision and the position where the detection signal reaches the second folding part 120 by the correction distance measuring unit 500 is within the preset difference range, it is considered that the distance c obtained by the distance measuring unit 400 with the first precision and the distance c obtained by the distance measuring unit 400 with the position where the detection signal reaches the second folding part 120 are accurate, otherwise, it is considered that the distance c obtained by the distance measuring unit 400 with the first precision and the distance c obtained by the detection signal reaches the second folding part 120 have an error, and re-measurement is required.
For example, the first precision corresponds to a precision value of 0.5 mm, the second precision corresponds to a precision value of 1 mm, when the distance measurement unit 400 obtains with the first accuracy that the detection distance c between the distance measurement unit 400 and the position where the detection signal reaches the second folding portion 120 is 11.5 mm, when the rectification ranging unit 500 acquires with the second accuracy that the detection distance c between the ranging unit 400 and the position where the detection signal reaches the second folding portion 120 is 11 mm or 12 mm, it is considered that the detection distance c between the distance measuring unit 400 and the position where the detection signal reaches the second folding portion 120, which is measured by the distance measuring unit 400, is accurate, and at this time, the folding angle is calculated according to the first accuracy obtained by the distance measuring unit 400 that the detection distance c between the distance measuring unit 400 and the position where the detection signal reaches the second folding portion 120 is equal to 11.5 mm.
Figure BDA0001937788280000122
If the corrected distance measuring unit 500 obtains, with the second accuracy, that the detection distance c between the distance measuring unit 400 and the position where the detection signal reaches the second folding portion 120 is 14 mm or 15 mm, it needs to be considered whether the detection distance c between the distance measuring unit 400 and the position where the detection signal reaches the second folding portion 120, which is measured by the distance measuring unit 400, is accurate, so as to measure the detection distance c again. Thus, the correction measureThe distance unit 500 is used as a reference for the distance unit 400 to evaluate the measurement parameters of the distance unit 400.
In the above embodiment, when the difference between the correction distance and the detection distance c is smaller than or equal to a first preset difference, the detection distance c is considered to be more accurate, and at this time, the processor 200 calculates the folding angle according to the detection distance c

Considering the calculated folding angle
Figure BDA0001937788280000124
And is also more accurate.
In the above embodiment, when the difference between the corrected distance and the detected distance c is greater than a first preset difference and smaller than a second preset difference, the processor 200 assigns a first weight coefficient to the detected distance c, the processor 200 assigns a second weight coefficient to the corrected distance, obtains a first calculated distance according to the detected distance c and the first weight coefficient, obtains a second calculated distance according to the corrected distance and the second weight coefficient, and calculates the folding angle according to an average value of the first calculated distance and the second calculated distance
Figure BDA0001937788280000131
Wherein the first weight coefficient is greater than the second weight coefficient, and the first preset difference is smaller than the second preset difference. That is, a larger weight coefficient is assigned to the detected distance c, a smaller weight coefficient is assigned to the corrected distance, and both the detected distance c and the corrected distance are used as the calculated folding angle
