The states whose distance is gradually remote can be sequentially defined as a first intermediate state, a second intermediate state, a third intermediate state, and the like.

It can be understood that, when the first carrier 10 and the second carrier 20 are in the first intermediate state, for example, the distance that the first carrier 10 and the second carrier 20 move away from the first intermediate state is a quarter H, The first carrier 10 and the second carrier 20 can still move away from each other to reach the second intermediate state, for example, the distance between the first carrier 10 and the second carrier 20 in the second intermediate state is one-half H. . It should be noted that, one or more intermediate states of the first carrier 10 and the second carrier 20 in the embodiments of the present application are merely illustrative, and do not constitute an intermediate state between the first carrier 10 and the second carrier 20 in the embodiments of the present application.

Furthermore, the flexible screen assembly 30 in the embodiment of the present application can be folded and unfolded electrically and magnetically, or can be folded and unfolded manually by the user.

It can be understood that, the first rotating shaft 41 can be directly or indirectly connected with the power mechanism 45 , so that the first rotating shaft 41 can rotate under the action of the power mechanism 45 . For example, the first rotating shaft 41 can be directly connected with the rotating shaft of the power mechanism 45; for another example, the first rotating shaft 41 can be connected with the power mechanism 45 through other connecting pieces.

It can be understood that, the second rotating shaft 42 can be connected to the first rotating shaft 41 through but not limited to transmission parts 44 such as belts, chains, racks and the like. The second rotating shaft 42 may be a passive rotating shaft, and the second rotating shaft 42 can rotate only when the first rotating shaft 41 is driven.

It can be understood that the moving gear shaft 43 can be directly or indirectly connected with the second rotating shaft 42. For example, as shown in FIG. 5 and FIG. 6, the moving gear shaft 43 can be directly coaxially disposed with the second rotating shaft 42 and directly connected , when the second rotating shaft 42 rotates, the moving gear shaft 43 can also rotate. For another example, as shown in FIG. 4 , the moving gear shaft 43 can be indirectly connected to the second rotating shaft 42 through other connecting parts including but not limited to connecting parts such as transmission gears.

For another example, please refer to FIG. 7. FIG. 7 is a schematic cross-sectional structure diagram of the electronic device shown in FIG. 2 along the M1-M2 direction. The moving gear shaft 43 can be connected to the second carrier 20, and the second carrier 20 can be connected to the flexible screen.

It can be understood that the above is only an exemplary description of the first transmission mechanism 40 in the embodiment of the present application, and the structure of the first transmission mechanism 40 in the embodiment of the present application is not limited to this. Others can make the flexible screen assembly 30 realize the first The structures of the switching first transmission mechanism 40 of the form and the second form are all within the protection scope of the embodiments of the present application.

It can be understood that the first shaft 41 can be connected to the first carrier 10 , the moving gear shaft 43 can be connected to the second carrier 20 , and the second shaft 42 can be connected to both the first carrier 10 and the second carrier 20 .

Exemplarily, as shown in FIG. 7 , when the second rotating shaft 42 is connected to the first carrier 10, since both the first rotating shaft 41 and the second rotating shaft 42 are located on the first carrier 10, the relative distance between them is not equal. Therefore, a transmission member 44 such as a transmission belt, a transmission rack, a transmission gear belt, etc. with a certain length is directly sleeved on the first rotating shaft 41 and the second rotating shaft 42. The length of the transmission member 44 can be the same as that of the first rotating shaft 41 and The distances between the second rotating shafts 42 are equal, and the transmission connection between the first rotating shaft 41 and the second rotating shaft 42 can be realized by the cyclic rotation of the first rotating shaft 41 and the second rotating shaft 42 of the transmission member 44 . At this time, since the moving gear shaft 43 is connected to the second carrier 20, when the second carrier 20 moves relative to the first carrier 10 in the direction of approaching or moving away from each other, the moving gear shaft 43 can be connected to the second carrier 20, flexible The screen assemblies 30 move together.

For example, please continue to refer to FIG. 4 , when the second shaft 42 is connected to the second carrier 20 , since the second carrier 20 can move relative to the first carrier 10 , the distance between the second shaft 42 and the first shaft 41 is It is not a fixed value, but also moves with the movement of the second carrier 20 . At this time, the length of the transmission member 44 sleeved on the first rotating shaft 41 and the second rotating shaft 42 may be equal to the distance between the first rotating shaft 41 and the second rotating shaft 42 after the electronic device 100 is unfolded. One end of the transmission member 44 is fixed to the second carrier 20 , and the other end of the transmission member 44 is wound around the first rotating shaft 41 and the second rotating shaft 42 and connected to the second rotating shaft 42 . When the first carrier 10 and the second carrier 20 are folded relative to each other, the conveyor belt can be retracted counterclockwise under the driving of the first rotating shaft 41 and the second rotating shaft 42 and wound on the second rotating shaft 42 . When the first carrier 10 and the second carrier 20 are unfolded relative to each other, the conveyor belt can be unfolded clockwise under the driving of the first rotating shaft 41 and the second rotating shaft 42 .

5 and 6, the second transmission mechanism 50 can be rotated under the driving of the moving gear shaft 43. At this time, the displacement detection component 60 can detect the rotational state of the driven gear 51, and the flexibility can be obtained according to the rotational state. The displacement parameter of the screen assembly 30 in the switching between the first form and the second form. Exemplarily, as shown in FIGS. 5 and 6 , the second transmission mechanism 50 may include a passive gear 51 , which may be meshed with the moving gear shaft 43 , and the passive gear 51 may also be directly or indirectly connected to the displacement detection assembly 60 . connect. Furthermore, under the action of the power provided by the power mechanism 45, when the moving gear shaft 43 is moved under the driving of the second rotating shaft 42, the driven gear 51 can also rotate with the movement of the moving gear shaft 43, so that the displacement detection assembly 60 also rotates. It can rotate with the rotation of the driven gear 51, and the displacement detection component 60 can detect the rotation state of the driven gear 51 and obtain the rotation parameters of the driven gear 51. When the two rotating shafts 42 are driven to move, the two move synchronously. Therefore, the displacement parameters of the flexible screen assembly 30 can be obtained according to the rotation parameters.

In the electronic device 100 of the embodiment of the present application, after the displacement detection component 60 detects the rotation parameter of the driven gear 51 , the motion state of the flexible screen component 30 can be obtained according to the displacement coefficient of the driven gear 51 and the moving gear shaft 43 . It can be understood that the coefficient of displacement can be the gear ratio between the gears. Since the speed of the gear with a large diameter is naturally slower than that of the gear with a small diameter, at the same speed, the rotation angles of the gears with different diameters are different, so in the When calculating the motion state of the flexible screen assembly 30 , the displacement coefficient among the driven gear 51 , the motion gear shaft 43 , and the displacement detection assembly 60 needs to be considered.

It can be understood that the gear sizes of the passive gear 51 and the moving gear shaft 43 can be equal, so that the displacement coefficient of the passive gear 51 and the moving gear shaft 43 is 1, so as to reduce the amount of calculation of the motion state of the flexible screen assembly 30 .

It can be understood that, as shown in FIG. 5 and FIG. 6 , the driven gear 51 can be coaxially connected with the displacement detection assembly 60. Under the same power, the rotation angle of the displacement detection assembly 60 and the driven gear 51 is consistent, and further, In the embodiment of the present application, there is no need to additionally calculate the displacement coefficient of the displacement detection component 60 and the driven gear 51 , and the structure of the second transmission mechanism 50 can be simplified.

Wherein, the second transmission mechanism 50 can also move linearly under the driving of the moving gear shaft 43 . At this time, the displacement detection component 60 can detect the linear motion state of the driven gear 51, and according to the linear motion state, the displacement parameter of the flexible screen component 30 in the switching between the first form and the second form can be obtained. Illustratively, please refer to FIG. 8 , which is a schematic structural diagram of a second transmission mechanism of an electronic device provided in an embodiment of the present application.

The second transmission mechanism 50 may include a link structure, and the link structure may include a first link 52, a second link 53 and a third link 54, wherein the first link 52 may be connected with the moving gear shaft 43, The first link 52 can move linearly with the moving gear shaft 43 under the driving of the moving gear shaft 43 . The second connecting rod 53 is hinged with the first connecting rod 52 , and a limiting through hole 531 is formed on the second connecting rod 53 . The third link 54 may include a fixed end and a moving end, the fixed end may be fixed with other parts of the electronic device 100 , and the moving end is limited in the limiting through hole 531 . When the first link 52 is driven linearly by the moving gear shaft 43 , the second link 53 drives the moving end of the third link 54 to linearly move within the limiting through hole 531 . Based on this, the displacement detection assembly 60 can be connected to the moving end of the third link 54, and further, under the action of the power provided by the power mechanism 45, when the moving gear shaft 43 is driven by the second rotating shaft 42, the entire The link structure can also move linearly with the movement of the moving gear shaft 43, so that the displacement detection component 60 can also move linearly with the movement of the entire link structure, and the displacement detection component 60 can detect the linear motion state of the link structure and obtain the linear motion. Displacement parameter, since both the flexible screen assembly 30 and the displacement detection assembly 60 are driven by the first rotating shaft 41 and the second rotating shaft 42, and the two move synchronously, therefore, the displacement of the flexible screen assembly 30 can be obtained according to the linear displacement parameter. parameter.

The second transmission mechanism 50 in the embodiment of the present application includes a link structure, and the link structure can increase the linear displacement ratio between the moving gear shaft 43 and the displacement detection assembly 60 . For example, when the moving gear shaft 43 drives the first link 52 of the link structure to move by 50 mm, under the action of the second link 53 and the third link 54 of the link structure, the displacement detection assembly 60 can only be displaced by 5 mm. At this time, the linear displacement ratio between the motion gear shaft 43 and the displacement detection assembly 60 is 10:1, so that the displacement detection assembly 60 can detect the larger motion gear shaft 43 and the flexible screen assembly 30 within a smaller linear motion range. The linear displacement parameter of , facilitates the detection of the displacement detection component 60 and improves the detection accuracy of the displacement detection component 60 .

It can be understood that the above is only an exemplary description of the second transmission mechanism 50 in the embodiment of the present application, and the structure of the second transmission mechanism 50 in the embodiment of the present application is not limited to this. Others can drive the displacement detection assembly 60 to detect the flexible screen. The second transmission mechanism 50 of the moving state of the assembly 30 in the switching state of the first state and the second state is within the protection scope of the embodiment of the present application.

Please refer to FIG. 9 , which is a schematic structural diagram of the displacement detection assembly shown in FIG. 5 . The displacement detection assembly 60 may include a fixed member 61 and a moving member 62 arranged at intervals, and the moving member 62 may be directly or indirectly connected with the second transmission mechanism 50 , for example, the moving member 62 is connected to the above-mentioned driven gear 51 and the moving end of the third link 54 Connected, and further, driven by the first transmission mechanism 40 and the second transmission mechanism 50 , the moving member 62 can move synchronously with the second carrier 20 and the flexible screen assembly 30 . The fixing member 61 can be directly or indirectly connected to the first carrier 10 , for example, the fixing member 61 is directly connected to the inner surface of the first carrier 10 , or the fixing member 61 can be connected to the circuit board 80 inside the first carrier 10 to realize Indirect connection to the first carrier 10 . The fixed part 61 can detect the movement state of the moving part 62. Since the moving part 62 moves synchronously with the movement of the flexible screen assembly 30, the movement state of the flexible screen assembly 30 can be detected according to the movement state of the moving part 62, and finally the flexible screen assembly is obtained. 30 displacement parameters.

The fixed member 61 can detect the linear motion state of the moving member 62 to obtain the linear displacement parameter of the moving member 62. For example, the moving member 62 can be linearly displaced under the driving of the second transmission mechanism 50 such as the moving end of the third link 54. The fixed member 61 can detect the linear movement distance of the moving part 62, and combined with the linear displacement ratio of the moving gear shaft 43 and the displacement detection component 60 generated by the link structure, the specific displacement parameters of the flexible screen component 30 can be detected. For example, when the moving member 62 moves from one end of the limiting through hole 531 of the third link 54 to a certain position under the driving of the link structure, when the fixed member 61 detects that the linear displacement distance of the moving member 62 is L , combined with the above-mentioned linear displacement ratio N, the specific displacement parameters S1 of the moving gear shaft 43 and the flexible screen assembly 30 can be calculated, S1=L·N, for example, when the fixed part 61 detects that the linear displacement distance of the moving part 62 is When L is 3 mm and the linear displacement ratio N is 10:1, the specific displacement parameter S1 of the moving gear shaft 43 and the flexible screen assembly 30 is 30 mm.

It can be understood that, the fixed member 61 can determine the linear movement distance of the moving member 62 according to the change of the magnetic flux, that is, the displacement detection component 60 can be a Hall linear displacement detection system. At this time, the moving member 62 may be a magnet, and the magnet is connected to the moving end of the third link 54 of the link structure. The fixing member 61 may be a magnetic sensor, and the magnetic sensor may be fixed on the circuit board 80 of the electronic device 100 and electrically connected with the circuit board 80 . Due to the characteristics of the magnet strength distribution of the permanent magnet, the magnetic sensor can detect magnetic fields of different sizes during the movement of the magnet. And the size of the magnetic field is linearly decreasing from the N pole of the magnet to the S pole of the magnet. The magnetic sensor can determine the displacement of the magnet by acquiring the change of the magnetic field strength.

In the electronic device 100 of the embodiment of the present application, the displacement detection assembly 60 adopts a Hall linear displacement detection system, and through the cooperation of the connecting rod structure, the magnetic sensor can detect the larger displacement of the flexible screen assembly 30 under the smaller displacement of the magnet, On the one hand, the displacement distance of the magnet is small, which can save the volume of the displacement detection assembly 60; more acurrate.

The fixed member 61 can also detect the rotation state of the moving member 62 to obtain the rotation parameters of the moving member 62. For example, the moving member 62 can rotate under the driving of the second transmission mechanism 50 such as the driven gear 51, and the fixed member 61 can detect the moving member. 62 Rotation parameters such as the number of turns and angles of rotation, and according to the rotation parameters, combined with the specific transmission structures of the first transmission mechanism 40 and the second transmission mechanism 50, the displacement parameters of the flexible screen assembly 30 can be detected. For example, it can be calculated according to the formula S2=(2πRA)/360. In this formula, S2 is the displacement parameter of the flexible screen assembly 30 , R is the radius of the driven gear 51 , and A is the rotation angle of the moving member 62 . Suppose, if the moving member 62 rotates two and a half turns driven by the driven gear 51, then A is 900 degrees, and the displacement parameter S2 of the flexible screen assembly 30 is S2=5πR.

It can be understood that the fixed member 61 can detect the position of a marking point 63 on the moving member 62 to determine the rotation parameter of the moving member 62 . For example, the fixing member 61 can detect the horizontal and vertical coordinates of the marking point 63, and calculate the rotation angle of the moving member 62 according to the horizontal and vertical coordinates of the marking point 63 at different positions. Exemplarily, please continue to refer to FIG. 6 , the fixing member 61 may be an angular Hall sensor, and the moving member 62 may be a circular magnet.

The fixing member 61 can be directly or indirectly connected to the first carrier 10. For example, the angular position Hall sensor can be fixed on the circuit board 80 of the electronic device 100, so as to be connected to the first carrier 10 through the circuit board 80, and the angular position Hall sensors may be electrically connected to the circuit board 80 to receive control from the circuit board 80 . The circular magnet may be coaxially connected to the driven gear 51 . For example, the circular magnet may be directly connected to one side of the driven gear 51 . Also, the circular magnet can rotate synchronously with the driven gear 51 .

The angular Hall sensor can be provided with a chip, an X-axis sensor, and a Y-axis sensor. The X-axis sensor can be used to detect the X-axis coordinates of the marking point 63 , and the Y-axis sensor can be used to detect the Y-axis coordinate of the marking point 63 . , so that the X-axis sensor and the Y-axis sensor can construct an XY coordinate system, and the coordinate origin O _{1 is} the intersection detected by the X-axis sensor and the Y-axis sensor. In addition, the X-axis sensor and the Y-axis sensor may be electrically connected to the chip, respectively, so as to store the detected X-axis coordinates and Y-axis coordinates of the marked point 63 in the chip.

It may include a uniform circular magnets N and S poles, the magnet magnetic fluxes circular center point O ₂ in the circumferential radiation therefrom. The center point O _{2 of the} circular magnet can be coaxial with the origin O ₁ of the XY coordinate system, and each magnetic field line of the circular magnet is mapped in the XY coordinate system as a radiation line radiating _{from the origin O 1 to the surrounding.} The starting point is the origin O ₁ , and the endpoints of the radiation line fall in the XY coordinate system. When the circular magnet rotates by a certain angle, when the X-axis sensor and Y-axis sensor of the angular Hall sensor detect the end point coordinates of one of the target magnetic lines of force mapped in the XY coordinate system, combined with the known initial position of the circular magnet, that is, The rotation angle of the center magnet can be detected. Exemplarily, assuming that when the circular magnet is in the initial position, the coordinates of the initial endpoint of the radiation line are (m1, 0), and after it rotates by a certain angle, the coordinates of the final endpoint of the radiation line are (m2, n), then you can The rotation angle A is calculated, tanA=n/m2.

It can be understood that the circular magnet can be located between the angular Hall sensor and the flexible screen assembly 30. At this time, the circumferential surface of the circular magnet, the XY coordinate system plane established by the angular Hall sensor, and the The display surfaces can be parallel to each other. Furthermore, the installation of the round magnet is smoother.

At this time, a Z-axis sensor can also be set in the angular Hall sensor, so that the X-axis sensor, the Y-axis sensor and the Z-axis sensor in the angular Hall sensor can establish a three-dimensional coordinate system, and the origin of the three-dimensional coordinate system ( Not shown in the figure) is _{coaxial with the center point O 2} of the circular magnet, and through this three-dimensional coordinate system, the coordinates of the endpoints of the target magnetic field lines mapped in the three-dimensional coordinate system can also be detected.

It can be understood that a gap can be set between the circular magnet and the angular Hall sensor to facilitate the distribution of the magnetic field lines. The distance of the gap can be 0.5 to 2 mm. Within this range, the magnetic field distribution of the circular magnet is more stable. , the change of the magnetic field line detected by the angular Hall sensor is more stable.

It can be understood that if the center point O _{2 of the} circular magnet is not coaxial with the XY coordinate system established by the internal sensor of the angular Hall sensor or the origin O _{1 of the} three-dimensional coordinate system, calibration needs to be done at this time, and the angular Hall The sensor can control the internal X-axis sensor, Y-axis sensor, and Z-axis sensor to replace the origin coordinates, so that the origin of the XY coordinate system or the three-dimensional coordinate system after calibration is coaxial with the center point of the circular magnet.

The fixed part 61 can obtain the motion state of the passive gear 51 by detecting the motion state of the moving part 62. Since both the passive gear 51 and the flexible screen assembly 30 are driven by the moving gear shaft 43, according to the movement of the passive gear 51 The motion state and displacement parameters of the flexible screen assembly 30 can be obtained from the motion state.

Wherein, after the electronic device 100 is powered on, the movement state of the flexible screen assembly 30 can be constantly detected by the displacement detection assembly 60 .
