The detection device is arranged on the flexible cavity 40, parameters of the detection device change along with the deformation of the flexible cavity 40, and the parameters of the detection device correspond to the folding angles between the first display screen 10 and the second display screen 20.
Specifically, in order to enable the flexible cavity to feed back the folded state of the two display screens quickly, and the placement position of the flexible cavity cannot affect the relative rotation between the two folded screens, the groove 301 is formed in the folded portion 30 in the present embodiment, the flexible cavity 40 is embedded into the groove 301, and the first side 401 of the flexible cavity is connected to the first display screen 10, the second side 402 of the flexible cavity is connected to the second display screen 20, in order to enable the feedback of the flexible cavity to be more accurate, the position of the flexible cavity can be further fixed, and the present embodiment can bond the surface of the flexible cavity, which is in contact with the folded portion, to the folded portion through the optical transparent adhesive.
In the embodiment of the invention, as the flexible cavity is embedded into the folding parts respectively connected with the first display screen and the second display screen, the flexible cavity is deformed under the condition that the first display screen rotates relative to the second display screen; because the detection device is arranged on the flexible cavity, the parameters of the detection device can change along with the deformation of the flexible cavity under the condition that the flexible cavity is deformed; and because the parameters of the detection device and the folding angle between the two display screens have corresponding relations, the folding angle between the two display screens can be determined according to the parameters of the detection device. Therefore, this embodiment detects folding angle's simple structure, and the flexible cavity of embedding folding portion can feed back the fold condition of two display screens fast, and the testing process is difficult for receiving external environment's interference, and measurement accuracy is high, can provide the application that different folding angles correspond for the user accuracy, effectively improves human-computer interaction's accuracy.
In the embodiment of the invention, the detection device comprises a light sensor and a light source; the light source is arranged on the first side face, the optical sensor is arranged on the second side face, light rays emitted by the light source are received by the optical sensor through diffuse reflection of the flexible cavity, and the optical sensor is used for determining a light intensity value of the light rays; the parameter of the detection device is a light intensity value, and the light intensity value changes along with the deformation of the flexible cavity.
Referring to fig. 2 to 5 in particular, fig. 2 shows a top view of the structure of a folding screen of the electronic device of the present invention, fig. 3 is a schematic structural diagram of a flexible cavity when the folding angle of the folding screen of the electronic device is 180 degrees according to the embodiment of the present invention, fig. 4 shows a schematic structural diagram of a flexible cavity when the folding angle of the folding screen of the electronic device is 0 deg. according to an embodiment of the present invention, figure 5 shows a schematic structural diagram of a flexible cavity when a folding angle of a folding screen of an electronic device is 360 degrees according to an embodiment of the invention, the detecting device comprises a light source 60 and a light sensor 50, the light source 60 can be a light emitting element such as a light emitting diode capable of emitting light, the light sensor 50 should match with the light source 60, and oppositely arranged, as shown in fig. 2 to 4, the light source 60 is arranged on the right side 401 of the flexible cavity, and the light sensor is arranged on the left side 402 of the flexible cavity. For example, if the light source 60 is an ultraviolet light emitting diode and the light sensor 50 is an ultraviolet light sensor, the specific types of the light source and the light sensor are not limited in the embodiment of the present invention, and of course, on the premise of the same function, a light source and a light sensor with low cost may be preferentially considered to reduce the total cost of the whole structure.
Specifically, the light emitted from the light source 60 is received by the light sensor 50 through the diffuse reflection of the flexible cavity 40, and it can be understood that, when a beam of incident light emitted from the light source 60 is incident on each surface inside the flexible cavity 40, because each surface of the flexible cavity 40 is a rough surface, the light on each surface is emitted toward all directions, a part of the emitted light is received by the light sensor 50, and the light sensor 50 determines the light intensity value thereof according to the received light, where the light intensity value in this embodiment is a parameter of the detection device. As shown in fig. 3 to 5, when a user manually folds the first display screen 10 or the second display screen 20, the flexible cavity 40 is deformed along with the folded state of the two display screens. Under the condition that the flexible cavity is deformed, the intensity of light reflected to the light sensor by light emitted by the light source can be changed, namely, the light intensity value determined by the light sensor is changed along with the deformation of the flexible cavity. Therefore, in practical application, the degree of deformation of the flexible cavity can be controlled by manually changing the folding state of the two display screens by a user, so that the light intensity value determined by the light sensor can be controlled by the degree of deformation of the flexible cavity.
In practical applications, the electronic device includes a processor 70 (not shown in the figures), the processor 70 is electrically connected to the light sensor 50, and the processor 70 may store a corresponding relationship between the light intensity value and the folding angle in advance, so that the processor 70 may determine the folding angle between the first display screen 10 and the second display screen 20 according to the corresponding relationship. For example, after each light intensity value and folding angle is obtained, a correspondence between the light intensity value and the folding angle may be established, for example, the light intensity values include: a0 and a1 … … a360, the folding angles corresponding to the light intensity values comprise: 0. 10 … … 360, the correspondence between the light intensity values and the fold angles can be as shown in table 1 below:
table 1:
| value of light intensity | Folding angle |
| a0 | 0 |
| |
10 |
| …… | …… |
| a36 | 360 |
After establishing the correspondence between each light intensity value and the folding angle, a table may be established, and the correspondence may be saved in the processor.
Of course, the folding angle may also be an angle interval, such as an interval every 10 °, and the light intensity values include: a0 and a1 … … a36, the folding angles corresponding to the light intensity values are 0-10 and 11-20 … … 350-360, and the corresponding relationship between the light intensity values and the folding angles can be shown in the following table 2:
Table 2:
| value of light intensity | Interval of folding angle |
| a0 | 0～10 |
| |
10～20 |
| …… | …… |
| a36 | 350～360 |
After establishing the correspondence between each light intensity value and the folding angle, a table may be established, and the correspondence may be saved in the processor.
In practical application, the deformation of the flexible cavity can feed back the folding angles of the two display screens in real time, so that the light sensor can send the light intensity value determined along with the deformation of the flexible cavity to the processor in real time, the processor can accurately determine the folding angle according to the corresponding relation between the prestored light intensity value and the folding angle, and thus, a user can accurately experience the application corresponding to different folding angles, and the accuracy of man-machine interaction is improved. In addition, the process of determining the folding angle is not easily influenced by external environment, such as the influence of a magnetic field, and the measurement precision is high.
In an embodiment of the present invention, the deformation of the flexible cavity is a change of a first distance, wherein the first distance is a distance between the first side surface and the second side surface.
Specifically, as shown in fig. 3 to 5, when a user folds the first display screen 10 or the second display screen 20, the two display screens rotate relatively, the flexible cavity 40 on the folding portion deforms along with the change of the folded state, when the folding angle is changed from 180 ° to 0 °, the distance between the left side 401 provided with the light source 60 and the right side 402 provided with the light sensor 50 becomes smaller, and when the folding angle is changed from 180 ° to 360 °, the distance between the first side 401 provided with the light source 60 and the second side 402 provided with the light sensor 50 becomes larger, that is, the distance between the first side 401 and the second side 402 increases along with the increase of the folding angle.
In the embodiment of the invention, the light-transmitting medium is filled in the flexible cavity, and the light intensity value decreases along with the increase of the first distance.
In practical applications, the flexible cavity 40 may be a sealed flexible light-transmitting cavity, and the flexible light-transmitting cavity may be made of a light-transmitting plastic material. The flexible light-transmitting cavity is internally provided with a containing cavity, the containing cavity is filled with a light-transmitting medium, and light can pass through the light-transmitting medium in the containing cavity. The light-transmitting medium of the embodiment may be a medium with a light-transmitting capacity that is weakened, so that when the distance between the first side surface provided with the light source and the second side surface provided with the light sensor is increased, the light-transmitting medium is increased, the light transmittance of the light emitted by the light source is reduced, and thus the light intensity value determined by the sensor according to the received light intensity is reduced, that is, the light intensity value is reduced along with the increase of the first distance, and conversely, the light intensity value is increased along with the reduction of the first distance.
In an embodiment of the present invention, the light transmissive medium is ozone.
Specifically, the light-transmitting medium according to the embodiment of the present invention may be a gas that reduces light penetration, such as ozone, or may be another gas, and the embodiment of the present invention does not limit the specific type of the light-transmitting medium.
In the embodiment of the invention, as the flexible cavity is embedded into the folding parts respectively connected with the first display screen and the second display screen, the flexible cavity is deformed under the condition that the first display screen rotates relative to the second display screen; because the flexible cavity has the first side and the second side that set up relatively, the light source sets up in first side, and light sensor sets up in the second side, and the light that the light source sent is received by light sensor through flexible cavity's reflection, and under the flexible cavity condition of taking place to warp, light sensor is according to the light intensity value of receiving light intensity affirmation, and the folding angle between two display screens can be confirmed to the processor according to the corresponding relation between light intensity value and the folding angle of prestoring. Therefore, this embodiment detects folding angle's simple structure, and the flexible cavity of embedding folding portion can feed back the fold condition of two display screens fast, and the testing process is difficult for receiving external environment's interference, and measurement accuracy is high, can provide the application that different folding angles correspond for the user accuracy, effectively improves human-computer interaction's accuracy.
In an embodiment of the present invention, the detecting device includes a first resistive plate and a second resistive plate; the flexible cavity comprises a first sub-cavity and a second sub-cavity which are communicated, and electrolyte solution is filled in the first sub-cavity and the second sub-cavity; the first resistance polar plate is arranged on the first side face of the first sub-cavity, the second resistance polar plate is arranged on the second side face of the first sub-cavity, and the electrolyte solution between the first resistance polar plate and the second resistance polar plate flows along with the deformation of the first sub-cavity, so that the resistance value between the first resistance polar plate and the second resistance polar plate changes.
Specifically, referring to fig. 6 to 8, fig. 6 shows a schematic structural diagram of a flexible cavity when a folding angle of a folding screen of another electronic device according to an embodiment of the present invention is 180 °, fig. 7 shows a schematic structural diagram of a flexible cavity when a folding angle of a folding screen of another electronic device according to an embodiment of the present invention is 0 °, and fig. 8 shows a schematic structural diagram of a flexible cavity when a folding angle of a folding screen of another electronic device according to an embodiment of the present invention is 360 °. Since the flexible cavity 40 includes a first sub-cavity 411 and a second sub-cavity 412 which are communicated with each other, the two sub-cavities are filled with electrolyte solution, and a first resistance plate 80 and a second resistance plate 90 are respectively arranged on two opposite sides of the first sub-cavity 411. Thus, under the condition that the first display screen 10 rotates relative to the second display screen 20, the flexible cavity 40 deforms, the electrolyte solution between the two resistance plates flows along with the deformation of the first sub-cavity 411, and a corresponding current value is generated, it can be understood that the two resistance plates can be respectively regarded as a positive electrode lead and a negative electrode lead, under the condition that the first sub-cavity 411 deforms, positive ions and negative ions in the electrolyte solution respectively move towards the negative electrode and the positive electrode under the action of an electric field, an oxidation-reduction reaction occurs on the electrodes, the positive ions obtain electrons at the negative electrode, and the negative ions transfer the electrons to the positive electrode, so that current can be formed and a corresponding current value is generated.
Specifically, the processor 70 in the electronic device is electrically connected to the first resistive plate 80 and the second resistive plate 90, respectively, since the voltage of the foldable screen mobile phone is a rated voltage, the processor 70 can calculate a resistance value according to a current value between the two resistive plates, and since the processor 70 stores a corresponding relationship between the resistance value and the folding angle in advance, the processor 70 can determine the folding angle between the first display screen 10 and the second display screen 20 according to the corresponding relationship. For example, after each resistance value and the folding angle are acquired, a correspondence between the resistance value and the folding angle may be established, for example, the resistance value includes: a0 and a1 … … a360, the folding angles corresponding to the resistance values comprise: 0. 10 … … 360, the correspondence between the resistance value and the fold angle can be as shown in table 1 below:
table 1:
after establishing the corresponding relationship between each resistance value and the folding angle, a table may be established, and the corresponding relationship may be saved in the processor.
Of course, the folding angle may also be an angle interval, such as an interval every 10 °, and the resistance value includes: a0, a1 … … a36, the folding angles corresponding to the resistance values are 0-10, 11-20 … … 350-360,
The correspondence between the resistance value and the folding angle can be as shown in the following table 2:
table 2:
| resistance value | Interval of folding angle |
| a0 | 0～10 |
| |
10～20 |
| …… | …… |
| a36 | 350～360 |
After establishing the corresponding relationship between each resistance value and the folding angle, a table may be established, and the corresponding relationship may be saved in the processor.
In practical application, since the first side 401 of the first sub-cavity 411 is connected to the first display screen 10 and the second side 402 of the first sub-cavity 411 is connected to the second display screen, when the first display screen 10 rotates relative to the second display screen 20, the first sub-cavity 411 deforms, taking the folding angle as a reference, and when the folding angle decreases from 180 ° to 0 °, as shown in fig. 6 and 7, the first sub-cavity 411 is squeezed, and the electrolyte solution in the first sub-cavity 411 flows into the second sub-cavity 412; as shown in fig. 6 and 8, when the folding angle increases from 180 ° to 360 °, first sub-chamber 411 is stretched and electrolyte solution in second sub-chamber 412 flows into first sub-chamber 411.
In practical application, the deformation of the flexible cavity can feed back the folding angles of the two display screens in real time, in this way, the current value between the first resistance polar plate and the second resistance polar plate determined along with the deformation of the first sub-cavity is sent to the processor, the processor calculates the resistance value according to the current value, then the folding angle is accurately determined according to the corresponding relation between the prestored resistance value and the folding angle, and thus, a user can accurately experience the application corresponding to different folding angles, and the accuracy of man-machine interaction is improved. In addition, the process of determining the folding angle is not easily influenced by external environment, such as the influence of a magnetic field, and the measurement precision is high.
In the embodiment of the invention, the deformation of the flexible cavity is the volume change of the first sub-cavity, and the resistance value is reduced along with the reduction of the volume.
Specifically, as shown in fig. 6 to 8, since the first side 401 of the first sub-chamber 411 is connected to the first display screen 10, and the second side 402 of the first sub-chamber 411 is connected to the second display screen 20, when the first display screen 10 rotates relative to the second display screen 20, the folding angle between the two display screens changes, the first sub-chamber 411 will deform correspondingly with the change of the folding angle, taking the folding angle as a reference of 180 °, when the folding angle decreases from 180 ° to 0 °, as shown in fig. 6 to 7, the first side 401 and the second side 402 are pressed, so that the volume of the first sub-chamber 411 decreases, the redundant electrolyte solution in the first sub-chamber 411 is squeezed into the second sub-chamber 412, the volume of the electrolyte solution in the first sub-chamber 411 decreases, and a current is generated due to the movement of positive and negative ions, so that, if the volume of the first sub-chamber 411 becomes smaller, the electrolyte solution in the first sub-chamber is less remained, the ion concentration is higher, and the current value is higher; the resistance plates on the two sides of the first sub-cavity 411 are respectively connected to the processor 70, and since the voltage of the folding screen mobile phone is the rated voltage, the processor 70 can calculate the resistance value between the two resistance plates according to the following formula 1 stored in advance,
R ═ U/I formula 1
In formula 1, R is resistance, U is voltage, and I is current. As can be seen from equation 1, the resistance is inversely proportional to the current, so that the resistance value decreases as the volume of the first sub-cavity decreases; conversely, when the folding angle is increased from 180 ° to 360 °, as shown in fig. 6 and 8, the first side 401 and the second side 402 are stretched, so that the volume of the first sub-chamber 411 is increased, that is, the second sub-chamber 412 is squeezed, and the extra electrolyte solution in the second sub-chamber 412 is squeezed into the first sub-chamber 411, so that the volume of the electrolyte solution in the first sub-chamber 411 is increased, and a current is generated due to the movement of positive and negative ions, so that if the volume of the first sub-chamber 411 becomes larger, the increased electrolyte solution in the first sub-chamber 411 is increased, the ion concentration is decreased, and the current value is decreased; the resistance plates on the two side surfaces of the first sub-cavity 411 are connected with the processor 70 respectively, and since the voltage of the folding screen mobile phone is the rated voltage, the processor 70 can calculate the resistance value between the two resistance plates according to the prestored formula 1, and the resistance value is inversely proportional to the current, so that the resistance value is increased along with the increase of the volume of the first sub-cavity 411.
In the embodiment of the invention, an insulating partition plate is arranged between the first sub-cavity and the second sub-cavity; the insulating partition plate is symmetrically provided with a first flow guide hole and a second flow guide hole, each flow guide hole is internally provided with a one-way valve, and the inlet directions of the two one-way valves are opposite.
Specifically, as shown in fig. 6 to 8, an insulating spacer 100 is disposed between the first sub-chamber 411 and the second sub-chamber 412; referring to fig. 9, which illustrates a schematic structural diagram of an insulating partition board in another flexible cavity of an electronic device according to an embodiment of the present invention, a first diversion hole 101 and a second diversion hole 102 are symmetrically disposed on the insulating partition board 100, each diversion hole is disposed with a check valve 103, and the inlet directions of the two check valves 103 are opposite, so that if the inlet direction of the check valve 103 on the first diversion hole 101 is from bottom to top, an electrolyte solution can only flow into the second sub-cavity 412 from the first sub-cavity 411, and if the inlet direction of the check valve 103 on the second diversion hole 102 is from top to bottom, the electrolyte solution can only flow into the first sub-cavity 411 from the second sub-cavity 412. In practical application, the folding angle is taken as 180 ° as a reference, when the folding angle is reduced from 180 ° to 0 °, the electrolyte solution in the first sub-chamber 411 flows into the second sub-chamber 412 from the first diversion hole 101, and when the folding angle is increased from 180 ° to 360 °, the electrolyte solution in the second sub-chamber 412 flows into the first sub-chamber 411 from the second diversion hole 102, so that the electrolyte solution can flow towards one direction, and the problem that the resistance value cannot be specifically determined due to backflow of the electrolyte solution, and further the folding angle cannot be accurately determined is avoided.
Optionally, a folding axis is formed in the folding portion after the first display screen and the second display screen are folded, and the flexible cavity is disposed in a central region of the folding axis.
Specifically, as shown in fig. 1, a folding axis 302 is formed in the folding portion 30 after the first display screen 10 and the second display screen 20 are folded, and the flexible cavity is disposed in a central area of the folding axis in this embodiment, because the precision of the folding angle between the two display screens fed back by the flexible cavity is higher, the flexible cavity may be disposed in other positions of the folding axis 302, and the specific disposition position is not specifically limited in this embodiment and is flexibly disposed according to actual requirements.
In practical application, as shown in fig. 2, a rotating shaft 100 may be disposed between the first display screen 10 and the second display screen 20, and the first display screen 10 and the second display screen 20 are rotatably connected through the rotating shaft 100, specifically, the rotating shaft 100 may include a first rotating shaft and a second rotating shaft, the second rotating shaft is disposed through the first rotating shaft, the first rotating shaft is connected with the first display screen 10 and can move along with the first display screen 10, and the second rotating shaft is connected with the second display screen 20 and can move along with the second display screen 20, so that when the first display screen 10 and the second display screen 20 are folded, the first rotating shaft and the second rotating shaft have relative motion.
