Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.
An electronic device 100 according to an embodiment of the application is described below with reference to fig. 1-3. The electronic device 100 may be a mobile phone, a tablet computer, etc.
As shown in fig. 1-2, an electronic device 100 according to an embodiment of the present application includes: flexible screen 1, trigger 2 and first sensor 3.
Specifically, at least a part of the flexible screen 1 is rollable, the flexible screen 1 has a first state and a second state, and an unfolded area of the flexible screen 1 in the first state is larger than an unfolded area of the flexible screen 1 in the second state. It follows that in the first state the developed area of the flexible screen 1 is relatively large. In the second state, the unfolded area of the flexible screen 1 is relatively small. It is understood that the larger the spread area of the flexible screen 1, the larger the display area of the electronic device 100 viewable by the user. The smaller the spread area of the flexible screen 1, the smaller the display area of the electronic device 100 viewable by the user. Therefore, the size of the display area can be changed by changing the unfolding area of the flexible screen 1, so that different visual requirements of users can be met, and the comfort of the users in using the electronic equipment 100 is improved.
The trigger 2 is fixedly connected with the free end of the flexible screen 1 to move synchronously with the free end of the flexible screen 1. It should be noted that the free end refers to the unfixed, movable end of the flexible screen 1. Thus, the flexible screen 1 can be moved between the first state and the second state by driving the free end of the flexible screen 1 to move, so that the size of the display area of the electronic device 100 can be changed to meet different visual requirements of users.
It can be seen that when the flexible screen 1 moves between the first state and the second state, the trigger 2 can move synchronously with the free end of the flexible screen 1, and when the trigger 2 moves to different positions, the trigger can be opposite to the first sensor 3 at different positions, and then the first sensor 3 at the corresponding position can detect that the trigger 2 is opposite to the trigger and emit a signal. The electronic control module of the electronic device 100 can thus obtain the signal emitted by the first sensor 3 and calculate the specific position of the free end of the flexible screen 1 from this signal. Further, the stroke of the flexible screen 1 can be effectively positioned, the position of the flexible screen 1 is determined, the unfolding area of the flexible screen 1 is determined, and the position and the size of the display area of the electronic device 100 are determined. Thereby, the electronic device 100 is made more intelligent. And meanwhile, the electronic equipment 100 is enabled to be simple and reliable in a mode of positioning the flexible screen 1.
According to the electronic device 100 of the embodiment of the application, at least a part of the flexible screen 1 is enabled to be curled, the trigger member 2 is fixedly connected with the free end of the flexible screen 1 to move synchronously with the free end of the flexible screen 1, the plurality of first sensors 3 are sequentially arranged in the moving direction of the free end of the flexible screen 1, the trigger member 2 sequentially opposes the plurality of first sensors 3 when the flexible screen 1 moves between the first state and the second state, each first sensor 3 is used for detecting whether the trigger member 2 opposes to the first sensor 3, and when the trigger member 2 opposes to the first sensor 3, the corresponding first sensor 3 emits a signal. Therefore, the size of the display area can be changed by changing the unfolding area of the flexible screen 1, so that different visual requirements of users can be met, and the comfort of the users in using the electronic equipment 100 is improved. The stroke of the flexible screen 1 can be effectively positioned, the position of the flexible screen 1 is determined, and the unfolding area of the flexible screen 1 is determined, so that the position and the size of the display area of the electronic device 100 are determined. Thereby, the electronic device 100 is made more intelligent. Meanwhile, the electronic device 100 can be positioned in a simple and reliable manner on the flexible screen 1.
According to some embodiments of the present application, the free end of the flexible screen 1 is movable between a first position and a second position, the flexible screen 1 being in a first state when the free end of the flexible screen 1 is moved to the first position; when the free end of the flexible screen 1 is moved to the second position, the flexible screen 1 is in the second state. It can be seen that, in the electronic device 100 in the embodiment of the present application, when the flexible screen 1 is in the first state, the free end of the flexible screen 1 is located at the first position, and at this time, the unfolded area of the flexible screen 1 is the largest, that is, the display area of the electronic device 100 is the largest, and the free end of the flexible screen 1 cannot move continuously in the direction from the second position to the first position. When the flexible screen 1 is in the second state, the free end of the flexible screen 1 is located at the second position, and at this time, the unfolding area of the flexible screen 1 is the smallest, that is, the display area of the electronic device 100 is the smallest, and the free end of the flexible screen 1 cannot move continuously in the direction from the first position to the second position. It will thus be appreciated that the first and second positions are extreme positions of the free end of the flexible screen 1.
As shown in fig. 1 and 2, in some embodiments of the present application, the electronic device 100 further includes a second sensor 4 and a third sensor 5, the trigger 2 is in contact with the second sensor 4 to cause the second sensor 4 to emit a signal when the flexible screen 1 is moved to the first state, and the trigger 2 is in contact with the third sensor 5 to cause the third sensor 5 to emit a signal when the flexible screen 1 is moved to the second state.
Therefore, when the free end of the flexible screen 1 moves to the first position, the trigger 2 contacts the second sensor 4, so that the second sensor 4 emits a signal, and after the electronic control module of the electronic device 100 acquires the signal, it can be determined that the free end of the flexible screen 1 has moved to the first position, the expansion area of the flexible screen 1 has reached the maximum, and the free end of the flexible screen 1 cannot move continuously in the direction from the second position to the first position. When the free end of the flexible screen 1 moves to the second position, the trigger 2 contacts with the third sensor 5, so that the third sensor 5 transmits a signal, and after the electronic control module of the electronic device 100 acquires the signal, it can be confirmed that the free end of the flexible screen 1 has moved to the second position, the expansion area of the flexible screen 1 has reached the minimum, and the free end of the flexible screen 1 cannot move continuously in the direction from the first position to the second position. Therefore, the electronic device 100 according to the embodiment of the application can effectively confirm the contraction limit and the expansion limit of the flexible screen 1 by setting the second sensor 4 and the third sensor 5, effectively remind the user that the flexible screen 1 has reached the movement limit, and is beneficial to avoiding the failure of the electronic device 100 caused by the fact that the user always applies external force to the flexible screen 1 when the flexible screen 1 needs the user to manually change the expansion area. And the safety and reliability of the use of the electronic device 100 can be improved. And the user can be clearly informed of the expansion area range of the flexible screen 1 of the electronic apparatus 100, i.e., the range of the display area.
In some embodiments of the present application, when the flexible screen 1 moves to the first state, the trigger member 2 presses the second sensor 4, and the second sensor 4 can detect the position of the trigger member 2 using ultrasonic waves and piezoresistance and emit a first limit signal; when the flexible screen 1 moves to the second state, the trigger 2 presses the third sensor 5, and the third sensor 5 detects the position of the trigger 2 by using ultrasonic waves and piezoresistance and emits a second limit signal. Therefore, when the free end of the flexible screen 1 moves to the first position, the trigger member 2 contacts the second sensor 4, and due to the inertia of the trigger member 2, there is a pressing force on the second sensor 4, and then the second sensor 4 can detect the position of the trigger member 2 by using the ultrasonic wave and the piezoresistive force and transmit the first limit signal, it can be understood that the first limit signal includes two signals (one is a signal transmitted after the detection by using the ultrasonic wave, and the other is a signal transmitted after the detection by using the piezoresistive force), thereby reminding the user that the spreading area of the flexible screen 1 has reached the maximum. When the free end of the flexible screen 1 moves to the second position, the trigger member 2 contacts the third sensor 5, and due to the inertia of the trigger member 2, there is an extrusion force on the third sensor 5, and then the third sensor 5 can detect the position of the trigger member 2 by using two modes, namely ultrasonic wave and pressure resistance, and transmit a second limit signal, it can be understood that the second limit signal includes two signals (one is a signal transmitted after detecting by using ultrasonic wave, and the other is a signal transmitted after detecting by using pressure resistance), thereby reminding a user that the spreading area of the flexible screen 1 has reached the minimum. Thereby making the use of the second sensor 4 and the third sensor 5 more reliable while the reliability of the electronic device 100 can be improved. Optionally, the second sensor 4 and the third sensor 5 are both modules of USM10000 manufactured by Ultra Sense.
According to some embodiments of the present application, the first sensor 3 may detect whether the triggering member 2 is opposite thereto using ultrasonic waves. It can be understood that, when the free end of the flexible screen 1 is moving, the triggering member 2 may be opposite to a different first sensor 3, and when the triggering member 2 is opposite to the first sensor 3, the corresponding first sensor 3 may detect the approach of an object by ultrasonic waves and output a signal. Therefore, the stroke of the flexible screen 1 can be effectively positioned, the position of the flexible screen 1 is determined, the unfolding area of the flexible screen 1 is determined, and the position and the size of the display area of the electronic device 100 are determined. Optionally, the first sensor 3 is a module of USM10000 manufactured by Ultra Sense. Specifically, the outer dimension of the first sensor 3 may be 1.4mm by 2.6mm, and when the first sensors 3 are arranged in different directions (for example, the front-back direction and the left-right direction in fig. 1 and 2), it is known that different positioning accuracies can be achieved, for example, when the first sensors 3 are arranged in the front-back direction, the width of each first sensor 3 is 1.4mm, and the positioning accuracy can reach 1.7mm (the width of the first sensor 3 is 1.4mm + the minimum spacing of the device patches is 0.3mm), when the first sensors 3 are arranged in different directions.
In some embodiments of the present application, the trigger 2 is a skin-like material. It is thus ensured that when the triggering part 2 is opposite the first sensor 3, the corresponding first sensor 3 can effectively detect the triggering part 2 and emit a signal. Or when the trigger 2 presses the second sensor 4 or the third sensor 5, the second sensor 4 or the third sensor 5 can effectively detect the position of the trigger 2 and transmit a signal. Therefore, the reliability of the electronic device 100 can be improved, and the effect of positioning the stroke of the flexible screen 1 by the electronic device 100 can be improved.
As shown in fig. 1 and 2, according to some embodiments of the present application, the electronic device 100 further includes a sliding member 6, the sliding member 6 is fixedly connected to the free end of the flexible screen 1 to move synchronously with the free end of the flexible screen 1, and the trigger member 2 is provided on the sliding member 6. It will thus be appreciated that the slider 6, the free end of the flexible screen 1 and the trigger 2 can be moved in synchronism. The trigger 2 is arranged on the sliding part 6, so that the trigger 2 can be supported by the sliding part 6, and the reliability of matching of the trigger 2 and the first sensor 3 is improved. Wherein slider 6 can be a slide rail, can set up another track with slider 6 complex in the electronic equipment 100 to slider 6 can slide in corresponding complex track, also can play spacing and guide effect to the removal of the free end of flexible screen 1 to a certain extent from this, improves the accuracy and the reliability that flexible screen 1 removed.
As shown in fig. 1 and 2, in some embodiments of the present application, the electronic device 100 further includes a connecting member 7, and the connecting member 7 is used for connecting the sliding member 6 and the free end of the flexible screen 1, so that the trigger member 2 and the free end of the flexible screen 1 move synchronously. Therefore, after the sliding part 6 is connected with the free end of the flexible screen 1 through the connecting part 7, the reliability of synchronous movement of the sliding part 6 and the flexible screen 1 can be guaranteed, and further the reliability of synchronous movement of the triggering part 2 and the free end of the flexible screen 1 can be guaranteed, so that the reliability of the stroke of the electronic device 100 for positioning the flexible screen 1 can be guaranteed, and the reliability of the electronic device 100 can be improved.
In some embodiments of the present application, the connecting member 7 is detachably connected to the sliding member 6 and the flexible screen 1, respectively. Therefore, the sliding part 6 and the flexible screen 1 can be conveniently connected and detached, the sliding part 6, the trigger part 2 and the flexible screen 1 can be conveniently maintained and replaced, and the service life of the electronic device 100 can be prolonged.
In some embodiments of the present application, the electronic device 100 further comprises a driving member, which cooperates with the sliding member 6 to drive the sliding member 6 to slide so as to drive the free end of the flexible screen 1 to move. Therefore, the electronic device 100 can finally drive the free end of the flexible screen 1 to move through the driving piece, so that the expansion area of the flexible screen 1 can be adjusted, different visual requirements of a user can be met, the comfort of the user using the electronic device 100 is improved, and the intelligent degree of the electronic device 100 is improved. Certainly, in other embodiments of the present application, a user may manually change the size of the expansion area of the flexible screen 1, so as to improve the experience of the user.
As shown in fig. 1 and 2, according to some embodiments of the present application, the electronic device 100 further includes a fixing member 8 and a PCB 9, the PCB 9 is disposed on the fixing member 8, and the plurality of first sensors 3 are disposed on the PCB 9. Therefore, the fixing member 8 can effectively support the PCB 9 and the plurality of first sensors 3, and facilitate the installation and fixation of the plurality of first sensors 3, thereby improving the reliability of the plurality of first sensors 3.
According to some embodiments of the present application, at least one of the two opposite ends of the flexible screen 1 is a free end, and each free end is provided with a trigger 2. It can be seen that, in the specific embodiment of the present application, one of the two opposite ends of the flexible screen 1 may be a free end, and also both of the two opposite ends of the flexible screen 1 may be free ends. The change in the developed area of the flexible screen 1 can thus be adjusted by moving only one of the free ends, or by moving both free ends simultaneously. And when the two opposite ends of the flexible screen 1 are free ends and one of the trigger pieces 2 is invalid or damaged, the unfolding area of the flexible screen 1 can be adjusted by moving the free end of the flexible screen 1 corresponding to the effective trigger piece 2, so that the stroke of the flexible screen 1 is positioned, and the position of the flexible screen 1 is determined. Thereby making the use of the electronic device 100 more flexible.
As shown in fig. 3, according to some embodiments of the present application, the electronic device 100 further includes a housing 10, a free end of the flexible screen 1 is located in the housing 10 and is movable relative to the housing 10, and the flexible screen 1 gradually extends into the housing 10 when the flexible screen 1 moves from the first state to the second state. Therefore, when the flexible screen 1 moves from the first state to the second state, the free end of the flexible screen 1 is located in the housing 10 and can move to gradually extend the flexible screen 1 into the housing 10, so that the unfolding area of the flexible screen 1 can be reduced, and the display area of the electronic device 100 can be reduced. When the flexible screen 1 moves from the second state to the first state, the free end of the flexible screen 1 is located in the housing 10 and can move to make the flexible screen 1 gradually extend out of the housing 10, so that the unfolding area of the flexible screen 1 can be increased, and the display area of the electronic device 100 can be increased. Moreover, the free end of the flexible screen 1 is arranged in the housing 10, so that the interference of the free end of the flexible screen 1 by external objects during movement can be effectively avoided, the housing 10 can protect the flexible screen 1 to a certain extent, and the reliability of the electronic device 100 is further improved.

According to the positioning method of the flexible screen 1 of the electronic device 100, the stroke of the flexible screen 1 can be positioned, the position of the flexible screen 1 is determined, the unfolding area of the flexible screen 1 is determined, and therefore the position and the size of the display area of the electronic device 100 are determined. Thereby, the electronic device 100 is made more intelligent. Meanwhile, the electronic device 100 can be positioned in a simple and reliable manner on the flexible screen 1.
According to some embodiments of the present application, the free end of the flexible screen 1 is movable between a first position and a second position, the flexible screen 1 being in a first state when the free end of the flexible screen 1 is moved to the first position; when the free end of the flexible screen 1 moves to the second position, the flexible screen 1 is in a second state; the electronic device 100 further comprises a second sensor 4 and a third sensor 5, the trigger 2 being in contact with the second sensor 4 to cause the second sensor 4 to emit a signal when the flexible screen 1 is moved to the first state, and the trigger 2 being in contact with the third sensor 5 to cause the third sensor 5 to emit a signal when the flexible screen 1 is moved to the second state.
Therefore, when the flexible screen 1 is in the first state, the free end of the flexible screen 1 is located at the first position, and at this time, the unfolded area of the flexible screen 1 is the largest, that is, the display area of the electronic device 100 is the largest, and the free end of the flexible screen 1 cannot move continuously in the direction from the second position to the first position. When the flexible screen 1 is in the second state, the free end of the flexible screen 1 is located at the second position, and at this time, the unfolding area of the flexible screen 1 is the smallest, that is, the display area of the electronic device 100 is the smallest, and the free end of the flexible screen 1 cannot move continuously in the direction from the first position to the second position. It will thus be appreciated that the first and second positions are extreme positions of the free end of the flexible screen 1. When the free end of the flexible screen 1 moves to the first position, the trigger piece 2 contacts with the second sensor 4, so that the second sensor 4 emits a signal, and after the electronic control module of the electronic device 100 acquires the signal, it can be confirmed that the free end of the flexible screen 1 has moved to the first position, the expansion area of the flexible screen 1 is maximized, the free end of the flexible screen 1 cannot move continuously in the direction from the second position to the first position, and then the maximum expansion position of the flexible screen 1 can be determined. When the free end of the flexible screen 1 moves to the second position, the trigger 2 contacts with the third sensor 5, so that the third sensor 5 emits a signal, and after the electronic control module of the electronic device 100 acquires the signal, it can be confirmed that the free end of the flexible screen 1 has moved to the second position, the expansion area of the flexible screen 1 is minimized, the free end of the flexible screen 1 cannot move continuously in the direction from the first position to the second position, and then the maximum contraction position of the flexible screen 1 at the moment can be determined.
The positioning method of the flexible screen 1 further comprises the following steps: acquiring a signal transmitted by any one of the first sensor 3, the second sensor 4 and the third sensor 5, and calculating the position of the free end of the flexible screen 1 according to the signal to position the flexible screen 1.
Therefore, according to the positioning method of the flexible screen 1 in the embodiment of the application, after the signal transmitted by any one of the first sensor 3 to the third sensor 5 is acquired, the position of the flexible screen 1 can be effectively confirmed, and the flexible screen 1 is positioned. Meanwhile, the contraction limit and the expansion limit of the flexible screen 1 can be effectively confirmed, the user is effectively reminded that the flexible screen 1 reaches the movement limit, and the electronic device 100 is beneficial to avoiding the failure of the electronic device 100 caused by the fact that the user always applies external force to the flexible screen 1 when the flexible screen 1 needs to manually change the expansion area. And the safety and reliability of the use of the electronic device 100 can be improved. And the user can be clearly informed of the expansion area range of the flexible screen 1 of the electronic apparatus 100, i.e., the range of the display area.
In some embodiments of the present application, the first sensor 3 may detect whether the trigger 2 is opposite thereto using ultrasonic waves, and the second sensor 4 and the third sensor 5 may detect the position of the trigger 2 and transmit signals using ultrasonic waves and piezoresistance, respectively. Thereby, the electronic device 100 is made reliable in the way of verifying the stroke of the flexible screen 1.
Specifically, as shown in fig. 1, when the flexible screen 1 is in the second state, the triggering member 2 is located at an initial position, at this time, the triggerable member 2 may be opposite to one of the leftmost ends of the plurality of first sensors 3, and the corresponding first sensor 3 may detect the triggering member 2 and send a signal to the electronic control module of the electronic device 100.
When the flexible screen 1 is gradually unfolded (i.e. moves from the second state to the first state), the trigger 2 will move synchronously (e.g. gradually move to the right in fig. 1 and 2) along with the free end of the flexible screen 1, the trigger 2 will sequentially contact with the plurality of first sensors 3 during the moving process, and each first sensor 3 will emit a detection signal when detecting that the trigger 2 is opposite to the first sensor 3, so as to determine the stroke of the flexible screen 1.
As shown in fig. 2, when the free end of the flexible screen 1 moves to the first position, it is described that the flexible screen 1 enters the first state, at this time, the trigger member 2 contacts the second sensor 4, and there is an extrusion force on the second sensor 4 due to the motion inertia of the trigger member 2, so that the second sensor 4 detects the trigger member 2 in two ways by using ultrasonic waves and piezoresistance, and transmits two interrupt signals to the electronic control module, thereby confirming that the expansion area of the flexible screen 1 reaches the maximum.
When the flexible screen 1 is gradually contracted (i.e. moved from the first state to the second state), the trigger 2 will move synchronously along with the free end of the flexible screen 1 (e.g. gradually move to the left in fig. 1 and 2), and the positioning principle of the flexible screen 1 is the same as that when the flexible screen 1 is gradually expanded, which is not described herein again.
As shown in fig. 1, when the free end of the flexible screen 1 moves to the second position, it is described that the flexible screen 1 enters the second state, at this time, the trigger 2 contacts with the third sensor 5, and there is an extrusion force on the third sensor 5 due to the motion inertia of the trigger 2, so that the third sensor 5 detects the trigger 2 in two ways by using ultrasonic waves and piezoresistance, and transmits two interrupt signals to the electronic control module, thereby confirming that the expansion area of the flexible screen 1 reaches the minimum.
