As shown in fig. 4(a), the electronic apparatus 100 includes: a connection unit 301, a main body 302, a main body 303, and a display screen 194. Wherein the connecting unit 301 is used to connect the main body 302 and the main body 303. The body 302 and the body 303 may be the same size or different sizes. The thickness of the body 302 and the body may be the same. The display screen 194 covers the connection unit 301, the main body 302, and the main body 303. The display screen 194 may be bent inward or outward by the connection unit to change an angle between the bodies. As shown in fig. 4(b), an angle a between the main body 302 and the main body 303 is an included angle between the main body 302 and the main body 303 (i.e., an angle smaller than 180 degrees).
Illustratively, as shown in fig. 5(a) and 5(b), the electronic device is in a flat state, which may also be referred to as an unfolded state. At this time, the main body 302 and the main body 303 are located on the same horizontal plane. The angle a between the body 302 and the body 303 is 180 degrees. As the user bends the display screen 194, the electronic device may be moved from a flat state to a folded state, or from a folded state to a flat state. As shown in fig. 5(b) and 5(d), the electronic apparatus is in a folded state. At this time, the main body 302 and the main body 303 are parallel to each other, the display screen 194 faces the inside of the electronic apparatus, and an angle α between the main body 302 and the main body 303 is 0 degree. When the display screen 194 is folded inward from the flat state to the folded state, the main body 302 and/or the main body 303 is/are rotated inward about the axis of the connection unit (as shown by the dotted line in fig. 5 (a)), the angle between the main body 302 and the main body 303 is gradually reduced, and the angle between the main body 302 and the main body 303 is gradually reduced from 180 degrees to 0 degree. The display screen 194 is folded outward from the folded state to the flat state, the main body 303 and/or the main body 303 is/are rotated outward about the axis of the connection unit, the angle between the main body 302 and the main body 303 is gradually increased, and the angle between the main body 302 and the main body 303 is increased from 0 degree to 180 degrees.
As shown in fig. 6(a) to 6(b), an object 500 to be tested is placed on any one of the main bodies of the electronic apparatus (e.g., the main body 302), and the other main body of the electronic apparatus (e.g., the main body 303) is bent inward so that the other main body rotates around the connection unit (e.g., the connection unit 301) until the object 500 to be tested comes into contact with the other main body. For example, the object 500 to be tested is in contact with the main body 303, the contact point being a point 600. Then, as shown in fig. 6(c), according to the sine law, the calculation formula of the height h of the object to be measured is shown as formula 1:

As shown in FIG. 6(d), L 1 Is the distance from the contact (e.g., point 600) to the connection unit (e.g., connection unit 301). The distance from the contact to the connection unit is the distance from the contact to the axis of the connection unit. For convenience of description, the axis of the connection unit may be referred to as a connection shaft.
That is, if the angle a between the two bodies and the distance L from the contact to the connection unit connecting the two bodies can be known 1 The height h of the object to be measured can be calculated.

Wherein the coordinate system is shown in FIG. 8(a) and FIG. 8(c), and x 3 The axis is the horizontal direction of the plane of the display screen 194; y is 3 The axis being in the plane of the display screen 194 and x 3 The axis is vertical.
For example, as shown in fig. 8(b), the object 500 to be measured is placed on the main body 302, the main body 303 is bent inward, the main body 303 is rotated inward around the axis of the connection unit 301 until being in contact with the object, a force acts on the point 600, the capacitance at the point 600 changes, the pressure sensor 701 determines the position of the point 600, and the coordinates (x, y) of the point 600 are output. It will be appreciated that, at this time, the distance L 1 Namely, the contact (e.g., point 600)Is different from the abscissa x of the touch point (e.g., point 600). Alternatively, as shown in fig. 8(d), the object 500 to be measured is placed on the main body 303, the main body 302 is bent inward, the main body 302 is rotated inward around the axis of the connection unit 301 until contacting the object 500, a force acts on the point 601, the capacitance at the point 601 changes, the pressure sensor 701 determines the position of the point 601, and the coordinates (x, y) of the point 601 are output.

alternatively, the electronic device 100 may determine the angle between the bodies through the gyro sensor 180B. For example, the electronic device may include a plurality of gyro sensors respectively provided in the bodies. The electronic apparatus may detect angular velocities of respective axes (e.g., x-axis, y-axis, and z-axis) of respective bodies (e.g., body 302, body 303) by gyro sensors provided in the respective bodies, may determine postures of the respective bodies (e.g., posture of body 302 and posture of body 303) from the detected angular velocities of the respective axes, and may further determine an angle between any one body and another body (e.g., determine an angle between body 302 and body 303 from the posture of body 302 and the posture of body 303).
Taking the bi-fold phone described in fig. 4 as an example, the electronic device 100 may include a first gyro sensor and a second gyro sensor. Wherein, the first gyro sensor is disposed at the main body 302; the second gyro sensor is provided in the main body 303. The electronic device 100 may calculate the posture of the main body 302 from the angular velocity detected by the first gyro sensor, and calculate the posture of the main body 303 from the angular velocity detected by the second gyro sensor; then, from the posture of the body 302 and the posture of the body 303, the electronic device may determine an angle between the body 302 and the body 303.
It should be noted that, in the embodiments of the present application, the method of identifying the angle between the bodies includes, but is not limited to, the above examples. For example, the electronic device 100 may determine an angle between the bodies through the acceleration sensor 180E and the gyro sensor 180B. As another example, the electronic device 100 also includes a rotation sensor. The electronic apparatus 100 may determine an angle between any one body and another body by detecting a rotation angle of the bodies by a rotation sensor.
In summary, the electronic device can identify the included angle (i.e., the angle less than 180 degrees) between the bodies.
Thus, the angle a between the body 302 and the body 303 identified by the electronic device and the distance L from the contact (e.g., point 600 or point 601) to the connection unit 301 1 The electronic device can calculate the height h of the object to be measured (e.g., the object 500), thereby measuring the height of the object. The method for measuring the height utilizes the deformable electronic equipment to measure the height of the object, and is simple to operate.
In the above embodiment, the object to be measured is taken as a cube as an example for description. It can be understood that the method for measuring height provided by the embodiment of the application can be used for measuring the height of objects with various shapes. For example, as shown in fig. 10 (a) and 10(b), the object to be measured may also be an irregularly shaped object such as a cone (e.g., object 501) or a trapezoid (e.g., object 502).
In the above embodiments, the object to be measured is placed on any one of the bodies of the electronic device, and the other body of the electronic device is bent inward. Optionally, according to another method for measuring height provided by the embodiment of the application, the object to be measured can be clamped between any one main body and another main body of the electronic device for measurement.
As shown in fig. 11(a), an object to be measured (e.g., an object 503) is sandwiched between two bodies (e.g., a body 302 and a body 303) so that one end of the object to be measured is in contact with any one body of the electronic apparatus (e.g., the body 303) with a first contact (e.g., a point 602), the other end of the object to be measured is in contact with the other body of the electronic apparatus (e.g., the body 302) with a second contact (e.g., a point 603). According to the cosine law, the calculation formula of the height h of the object to be measured is shown as formula 6:
h 2 ＝L 2 2 +L 3 2 -2L 2 L 3 cos alpha (formula 6)
Where, a is an angle between the two bodies (e.g., the angle between the body 302 and the body 303). L is 2 Is the distance from the first contact (e.g., point 602) to the connection unit (e.g., connection unit 301). L is 3 Is the distance from the second contact (e.g., point 603) to the connection unit (e.g., connection unit 301).
The distance from the first contact to the connection unit is a distance from the first contact to an axis of the connection unit, and the distance from the second contact to the connection unit is a distance from the second contact to the axis of the connection unit.
Therefore, according to the angle alpha between the two main bodies identified by the electronic equipment and the distance L from the first contact to the connecting unit 1 And a distance L from the second contact to the connection unit 2 The electronic device can calculate the height h of the object to be measured (e.g., the object 503), thereby measuring the height of the object. Wherein the electronic device can recognize the distance L from the first contact to the connection unit by means of the pressure sensor 2 Distance L of the second contact to the connection unit 3 . The electronic device identifies a distance L from the first contact to the connection unit 2 Method L of distance of second contact to connection unit 3 For reference, the above embodiments are not described herein again.
Therefore, the electronic equipment can measure the object to be measured with higher height.
It should be noted that, in the above embodiments, the double-folding mobile phone is taken as an example for description, and it is understood that the electronic device may be connected to more main bodies through more connecting units. For example, the electronic device may be a tri-fold phone. Fig. 12 is a schematic structural diagram of another electronic device 100 according to an embodiment of the present application. As shown in fig. 12, the electronic apparatus 100 includes: a connection unit 401, a connection unit 402, a body 403, a body 404, and a body 405. The connection unit 401 is used to connect the body 403 and the body 404, and the connection unit 402 is used to connect the body 404 and the body 405. The display screen 194 covers the connecting unit 401, the connecting unit 402, the main body 403, the main body 404, and the main body 405. The body 402, 403 and 404 may be the same size or the same thickness. The display screen 194 may be bent inward or outward by the connection unit 401, whereby the main body 403 and the main body 404 may be rotated about an axis (shown by a dotted line on the left side of fig. 12) of the connection unit 401 to change an angle between the main body 403 and the main body 404; the display screen 194 may be bent inward or outward by the connection unit 402, whereby the main body 404 and the main body 405 may be rotated about an axis of the connection unit 403 (as shown by a dotted line on the right side of fig. 12) to change an angle between the main body 404 and the main body 405.
In the above embodiment, the electronic device 100 in which the main body 301 and the main body 302 have the same size is taken as an example for explanation, and it is understood that the main body 302 and the main body 303 may have different sizes. For example, as shown in fig. 13(a), the body 302 may be larger in size than the body 303. The body 403, body 404 and body 405 may also be different sizes. For example, as shown in fig. 13 (b), the sum of the widths of the body 403 and the body 405 is equal to the width of the body 404.
It will be appreciated that, similarly, the electronic device 100 may identify an angle between any two bodies, such as: the angle between body 403 and body 404, the angle between body 404 and body 405, and the angle between body 403 and body 405.

Reference is made to the description of fig. 9, which is not repeated herein.
It is understood that electronic device 100 similarly includes one or more pressure sensors. For example, the electronic device 100 may include pressure sensors 700a, 700b, 700 c. The pressure sensor 700a is provided on the main body 403, the pressure sensor 700b is provided on the main body 404, and the pressure sensor 700c is provided on the main body 405. The electronic device 100 may identify a distance from any contact to the connection unit through the pressure sensor, and the detailed method refers to the description of the above embodiments and is not described herein again.
It is to be understood that, similarly, as shown in fig. 14, an object to be measured is placed on either main body, and then the other main body is brought into contact with the object to be measured by bending the display screen 194. The electronic apparatus 100 identifies an angle a between the arbitrary two bodies and a distance L from the contact to the connection unit 1 According to the angle alpha and the distance L 1 And calculating to obtain the height of the object to be measured. Although not shown in the drawings, an object to be measured may be placed between any two main bodies, the display screen 194 is bent so that one end of the object contacts with any one main body, the other end of the object contacts with the other main body, and then an angle a between the main bodies of the electronic device, a distance L from the first contact to the connection unit 2 And the distance L from the second contact to the connection sheet 3 According to the angle alpha, the distance L 2 And a distance L 3 And calculating to obtain the height of the object to be measured. The detailed process is described with reference to fig. 6 to 11, and is not repeated herein.
The method provided by the embodiment shown in fig. 15 below is applied to the electronic device provided by each of the foregoing embodiments. As shown in fig. 15, an embodiment of the present invention provides a method for measuring height, including:
step 1501, the electronic device receives a first input of a user.
Wherein the first input is for instructing the electronic device to begin measuring the height of the object.
Illustratively, as shown in fig. 16(a), the user touches an icon 801 to open a measurement application. In response to the icon 801 being touched, the electronic device opens a measurement application. As shown in fig. 16(b) and 16(c), the electronic device may display interface 902 and/or interface 903. Interface 902 or interface 903 may include instructions for informing a user how to measure the height of an object using the electronic device. Interface 902 or interface 903 may include a start measurement button 802. The measurement button 802 is used to instruct the electronic device to start measuring the height of the object. The electronic device receives a first input from a user. Illustratively, the first input may be: the user touches the start measurement button 802.
Step 1502, in response to the first input, the electronic device triggers the pressure sensor.
In step 1503, the electronic device detects whether the object to be detected is in contact with the main body of the electronic device through the pressure sensor.
If so, go to step 1504; if not, step 1503 is repeated.
Specifically, the user places the object to be measured on the first main body, bends the second main body inwards, and the second main body rotates around the axis of the connecting unit until the vertex of the object to be measured contacts the second main body. When the vertex of the object to be measured is in contact with the second main body, a force acts on the pressure sensor arranged on the second main body, the capacitance between the electrodes of the pressure sensor is changed, and the electronic equipment determines that the object to be measured is in contact with the second main body. On the contrary, when the object is not in contact with the second body, the capacitance between the electrodes of the pressure sensor arranged on the second body is not changed, and the electronic device determines that the object to be measured is not in contact with the second body. If the electronic device determines that the object to be tested is in contact with the second body, step 1504 is executed. If the electronic device determines that the object to be tested is not in contact with the second main body, step 1503 is executed repeatedly.
Illustratively, as shown in fig. 17(a) to 17(b), the user places the object 500 to be tested on the main body 302, and bends the main body 303 inward until the vertex a of the object 500 to be tested contacts the main body 303. When a force acts on the pressure sensor 700b, the capacitance between the electrodes of the pressure sensor 700b changes, and the electronic device determines that the object to be measured is in contact with the main body 303. It is understood that, at this time, the first body is the body 302, and the second body is the body 303.
For example, as shown in fig. 17(d) to 17(e), the user places the object 500 to be tested on the main body 404 and bends the main body 405 inward until the vertex a of the object 500 to be tested contacts the main body 405. It will be appreciated that at this point, the first body is body 404 and the second body is body 405.
Alternatively, although not shown in the drawings, the user may place the object between the first body and the second body, and bend the first body and/or the second body inward until one end of the object to be measured contacts the first body and the other end of the object to be measured contacts the second body. When one end of the object to be detected is in contact with the first main body, a force acts on the pressure sensor arranged on the first main body, the capacitance between the electrodes of the pressure sensor is changed, and the electronic equipment determines that the object to be detected is in contact with the first main body. On the contrary, when the object is not in contact with the first body, the capacitance between the electrodes of the pressure sensor arranged on the first body is not changed, and the electronic equipment determines that the object to be measured is not in contact with the first body. When the other end of the object to be measured is in contact with the second main body, a force acts on the pressure sensor arranged on the second main body, the capacitance between the electrodes of the pressure sensor is changed, and the electronic equipment determines that the object to be measured is in contact with the second main body. On the contrary, when the object is not in contact with the second body, the capacitance between the electrodes of the pressure sensor arranged on the second body is not changed, and the electronic device determines that the object to be measured is not in contact with the second body. When the electronic device determines that the object is in contact with the first body and the object is in contact with the second body, step 1504 is performed. When the electronic device determines that the object is not in contact with the first body or the object is not in contact with the second body, step 1503 is repeatedly performed.
At step 1504, the electronic device identifies an angle a between the first body and the second body.
Illustratively, as shown in fig. 17(b), the angle between the first body and the second body is the angle between the body 302 and the body 303. Alternatively, as shown in fig. 17(e), the angle between the first body and the second body is the angle between the body 404 and the body 405. The method for the electronic device to identify the angle between the first body and the second body is described in the above embodiments, and is not repeated here.
Step 1505, the electronic device identifies a distance of the contact to a connection unit connecting the first body and the second body.
Specifically, the electronic apparatus recognizes a distance L from the contact to the connection unit connecting the first body and the second body 1 。
Illustratively, as shown in fig. 17(b), the distance from the contact to the connection unit connecting the first body and the second body is the distance from the point 604 to the connection unit 301. Alternatively, as shown in fig. 17(e), the distance from the contact to the connection unit connecting the first body and the second body is the distance from the point 605 to the connection unit 402. The method for identifying the distance by the electronic device is described in the above embodiments, and is not described herein again.
Alternatively, the electronic device identifies the distance L from the first contact to the connection unit 2 And a distance L from the second contact to the connection unit 3 . The method for determining the distance of the electronic device is described in the above embodiments, and is not described herein again.
And step 1506, the electronic equipment calculates the height of the object to be measured according to the angle and the distance.
Specifically, the electronic device may be configured to determine the angle a and the distance L according to the angle a 1 And calculating the height h of the object to be measured.
Angle alpha and distance L 1 The electronic device can calculate the height h of the object to be measured according to formula 1.
Alternatively, the electronic device may be configured to use the angle a and the distance L 2 The distance L 3 And calculating the height h of the object to be measured. Angle alpha and distance L 2 The distance L 3 The electronic device can calculate the height h of the object to be measured according to formula 6.
Step 1507, the electronic device outputs the height h.
For example, as shown in fig. 17(c) and 17(f), the electronic device may display the height h on the display screen 194. Alternatively, for convenience of the user's view, the electronic device may display the height on a display screen 194 covering the second body, as shown in fig. 17 (c); alternatively, as shown in fig. 17(f), the electronic device may display the height on the display screen 194 overlaid on other bodies (e.g., the body 403) other than the first body and the second body.
Alternatively, the electronic device may output the height h in speech. For example, the electronic device may output a voice message of "measure the height of the object is 5 cm".
It should be noted that, in the height measuring method illustrated in fig. 15, the position of the contact is detected by the pressure sensor to measure the height of the object. It will be appreciated that alternatively, the electronic device may detect the location of the contact point via the touch sensor.
Alternatively, as shown in fig. 18, the electronic device may also display a reference line on the display screen, so that the user can place the object to be measured by aligning the reference line.
Illustratively, as shown in fig. 18(a), the electronic device displays a reference line 1400 on the main body 303. The distance between the reference line 1400 and the connection unit 301 is D 1 . As shown in fig. 18(b) and 18(c), the user bends the main body 303 inward so that the apex of the object 500 contacts the main body 303 and the point of contact is on the reference line 1400. The electronic device identifies an angle a between the body 302 and the body 303. The electronic equipment is based on the distance D 1 And calculating the height h of the object by the angle alpha, wherein a calculation formula is shown as formula 7:
h＝D 1 xsin alpha (formula 7)
Alternatively, in order to facilitate the measuring operation of the user, when the object to be measured is a regular object such as a cube, as shown in fig. 18(D), the electronic device may also display the reference line 1400 on the main body 302, where the distance between the reference line 1400 and the connection unit 301 is D 2 . As shown in fig. 18(e) and 18(f), the user bends the body 303 inward so that the apex of the object 500 comes into contact with the body 303. The electronic device identifies an angle a between the main body 302 and the main body 303. The electronic equipment calculates the height h of the object according to the distance D2 and the angle alpha, and a calculation formula is shown in formula 8:
h＝D 2 x tan alpha (formula 8)
In summary, according to another height measuring method provided by the embodiment of the present application, the step of detecting the contact point by the pressure sensor can be omitted by displaying the reference line on the display screen. The method can be used for electronic devices without pressure sensors.
