Detailed Description
Reference will now be made in detail to the 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 accompanying drawings are illustrative 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. 1-4. The electronic device 100 may be a mobile phone or a tablet computer.
As shown in fig. 1 to 3, an electronic device 100 according to an embodiment of the present application includes: the device comprises a shell 1, a state detection device 6, an electrowetting member 2 based on the electrowetting effect and a control device 7.
The condition detection means 6, the control means 7 and the electrowetting element 2 are located within the housing 1. Thus, the housing 1 can protect the components placed inside the housing 1, and the appearance of the electronic apparatus 100 can be improved.
Specifically, the state detection device 6 may be configured to detect a current motion state of the electronic apparatus 100, the state detection device 6 is electrically connected to the control device 7, and the current motion state of the electronic apparatus 100 detected by the state detection device 6 may be fed back to the control device 7, so that the control device 7 performs a corresponding action.
The control device 7 is electrically connected with the electrowetting element 2, and when the state detection device 6 detects that the electronic device 100 is in a falling state and the electronic device 100 is not parallel to the horizontal plane, the control device 7 applies a voltage to the electrowetting element 2 to adjust the falling posture of the electronic device 100.
It can be understood that the Electrowetting element 2 is processed based on the Electrowetting effect, and Electrowetting (EW) refers to a phenomenon that wettability of a liquid drop on a substrate is changed by changing voltage between the liquid drop and an insulating substrate, that is, a contact angle is changed, so that the liquid drop is deformed and displaced, wherein wetting refers to a process that one fluid on a solid surface is replaced by another fluid, the liquid can spread on the solid surface, and a solid-liquid contact surface has a tendency to expand, that is, an adhesive force of the liquid to the solid surface is greater than a cohesive force of the liquid, and wetting refers to wetting. The liquid can not spread on the solid surface, and the contact surface has the tendency of shrinking into a spherical shape, namely, the liquid is not wetted, or the liquid has smaller adhesive force to the solid surface than the cohesive force.
Specifically, the electrowetting element 2 comprises a body and a conductive liquid 24, wherein the body is provided with a closed space, and the conductive liquid 24 is positioned in the closed space and can move in the closed space. Specifically, referring to fig. 4, the body includes a first plate 21 and a second plate 22, the first plate 21 and the second plate 22 are disposed opposite to each other, and further, in order to form a sealed space, the body further includes a surrounding wall 23, the surrounding wall 23 surrounds the first plate 21 and the second plate 22 to define the sealed space with the first plate 21 and the second plate 22, the first plate 21 includes a first substrate 211, a transparent electrode 212, and a hydrophobic film 213, the transparent electrode 212 is disposed on a side of the first substrate 211 facing the second plate 22, the hydrophobic film 213 is disposed on a side of the transparent electrode 212 facing the second plate 22, the second plate 22 includes a second substrate 221, a micro-electrode array 222, an insulating layer 223, and a hydrophobic layer 224, the micro-electrode array 222 is disposed on a side of the second substrate 221 facing the first plate 21, the insulating layer 223 is disposed on a side of the micro-electrode array 222 facing the first plate 21, the hydrophobic layer 224 is disposed on a side of the insulating layer 223 facing the first electrode plate 21, the conductive liquid 24 is disposed between the hydrophobic layer 224 and the hydrophobic film 213, and the surrounding of the conductive liquid 24 may be air. Specifically, the movement of the conductive liquid 24 on the microelectrode array 222 is controlled by applying a voltage to the electrodes in the microelectrode array 222 and the transparent electrode 212, and when the voltage applied to one of the electrodes in the microelectrode array 222 reaches a certain value, the conductive liquid 24 moves to the charged electrode under the action of surface tension, so that the moving direction of the conductive liquid 24 can be controlled according to actual needs. The specific working principle of the electrowetting element 2 is well known to those skilled in the art and will not be described in detail here.
Generally, due to the influence of factors such as the position distribution of electronic components with different masses in the electronic device 100 and the airflow in the air, a certain included angle exists between a plane where the electronic device 100 is located and a horizontal plane in the process of dropping the electronic device 100, so that one corner of the electronic device 100 impacts the ground. In the electronic device 100 in the related art, although the area of the display screen is large, since the display screen does not extend to the side of the electronic device 100, the striking manner of the corner described above is not so much damage to the display screen because the middle frame 11 of the electronic device 100 is struck first. However, the inventors have surprisingly found in experiments that, for a full-screen electronic device 100 in which the display screen extends to the side and the corner of the electronic device 100, the above-mentioned impact manner is more likely to damage the full-screen electronic device 100 due to stress concentration at the corner of the electronic device 100.
In view of this, in the embodiments of the present application, the state detection means 6 may be used to detect the current motion state of the electronic device 100, when the state detection device 6 detects that the electronic apparatus 100 is in a falling state, and the electronic apparatus 100 is not parallel to the horizontal plane, the control means 7 may control the electrowetting element 2 to apply different voltages to the transparent electrode 212 and the array of microelectrodes 222, so that the conductive liquid 24 of the electrowetting element 2 can be moved upwards in the closed space, so that the centre of gravity of the electronic device 100 can be adjusted, and then adjust and fall the gesture, can make electronic equipment 100 strike with the ground with the gesture of falling that is parallel with ground to a certain extent at least, be favorable to making electronic equipment 100 fall the four corners or the side of in-process display screen and do not receive the impact to a certain extent at least to can play the effect of protection display screen to a certain extent at least.
According to the electronic device 100 of the embodiment of the application, by arranging the electrowetting element 2, when the state detection device 6 detects that the electronic device 100 is in a falling state, and the electronic device 100 is not parallel to a horizontal plane, the control device 7 can control the electrowetting element 2 to apply different voltages to the transparent electrode 212 and the microelectrode array 222, so that the conductive liquid 24 of the electrowetting element 2 can move upwards in a closed space, thereby adjusting the falling posture of the electronic device 100, and at least to a certain extent, the electronic device 100 can be impacted with the ground in a falling posture parallel to the ground, which is beneficial to at least protecting four corners or sides of the display screen in the falling process of the electronic device 100 from impact, thereby at least to a certain extent playing a role in protecting the display screen.
In some embodiments of the present application, as shown in fig. 2, the housing 1 includes: a middle frame 11 and a rear shell 12, the rear shell 12 is arranged at the rear side of the middle frame 11 and connected with the middle frame 11, the control device 7 is arranged on the middle frame 11, and the electrowetting element 2 is positioned between the middle frame 11 and the rear shell 12. Thereby, not only the structure is simple, but also the control device 7 is arranged relatively close to the electrowetting element 2, facilitating the connection between the two.
In some embodiments of the present application, as shown in fig. 3, a side surface of the rear case 12 facing the middle frame 11 is provided with a groove 121 recessed toward a direction away from the middle frame 11, and the electrowetting element 2 is located in the groove 121. Thus, by providing the recess 121 and disposing the electrowetting element 2 in the recess 121, the overall thickness dimension of the electronic device 100 is advantageously reduced.
In some embodiments of the present application, the battery 4 is mounted on a surface of the middle frame 11 facing the rear case 12, and the electrowetting element 2 is directly opposite to the battery 4 in a thickness direction of the electronic device 100. Specifically, for the electronic apparatus 100, the battery 4 is a relatively heavy device, and by aligning the electrowetting element 2 with the battery 4 in the thickness direction of the electronic apparatus 100, the electrowetting element 2 can be disposed adjacent to the center of gravity of the electronic apparatus 100, thereby being more advantageous for adjusting the falling posture of the electronic apparatus 100.
In some embodiments of the present application, a surface of the middle frame 11 facing the rear case 12 is provided with a mounting groove (not shown) recessed toward a direction away from the rear case 12, and the battery is located in the mounting groove. Thereby, the overall thickness dimension of the electronic apparatus 100 is advantageously reduced.
In some embodiments of the present application, a portion of the electrowetting element 2 extends into the mounting slot, and the electronic device 100 further comprises a sealing foam (not shown) filled between an outer circumferential wall of the electrowetting element 2 and an inner circumferential wall of the mounting slot. This is advantageous for improving the protection effect of the battery and the electrowetting element 2 and for avoiding the shaking of the electrowetting element 2 and the battery 4.
According to some embodiments of the application, in a plane m parallel to the electronic device 100, an outer contour of a projection of the battery 4 in the plane m coincides with an outer contour of a projection of the electrowetting element 2 in the plane m. Therefore, the electronic device 100 is not only simple in structure, but also more beneficial to adjusting the falling posture of the electronic device 100.
According to some embodiments of the present application, the electrowetting element 2 is attached to the surface of the rear shell 12 on the side facing the center frame 11 by means of an adhesive layer 5. Specifically, for example, a groove 121 recessed toward a direction away from the center frame 11 is provided on a surface of the rear case 12 on a side facing the center frame 11, and the electrowetting element 2 is stuck in the groove 121 by the adhesive layer 5. This is advantageous in that the mounting of the electrowetting element 2 is simplified and is secure.
In some specific examples, the adhesive layer 5 is a double-sided adhesive layer. Thus, the cost is low.
In some embodiments of the present application, a surface of the rear housing 12 facing the middle frame 11 is provided with a hook (not shown) extending toward a direction close to the middle frame 11, and a hook portion of the hook hooks a side surface of the electrowetting device 2 facing the middle frame 11. Specifically, for example, a groove 121 recessed in a direction away from the middle frame 11 is provided on a side surface of the rear case 12 facing the middle frame 11, the electrowetting element 2 is located in the groove 121, a hook is provided on a portion of the surface of the rear case 12 facing the middle frame 11, which surrounds the groove 121, and extends in a direction close to the middle frame 11, and a hook portion of the hook hooks a side surface of the electrowetting element 2 facing the middle frame 11 to confine the electrowetting element 2 within the groove 121. Therefore, the structure is simple, the electrowetting element 2 and the rear shell 12 can be detachably mounted, and the mounting and the dismounting are convenient.
In order to further improve the reliability of the mounting of the electrowetting element 2, in some specific examples, a groove 121 recessed toward a direction away from the middle frame 11 is provided on a side surface of the rear casing 12 facing the middle frame 11, the electrowetting element 2 is adhered in the groove 121 by the adhesive layer 5, a hook is provided on a portion of the surface of the rear casing 12 facing the middle frame 11 surrounding the groove 121, the hook extends toward a direction close to the middle frame 11, and a hook portion of the hook is hooked on a side surface of the electrowetting element 2 facing the middle frame 11 to restrain the electrowetting element 2 in the groove 121.
In some embodiments of the present application, the depth dimension of the groove 121 ranges from 0.5 mm to 1.2 mm. For example, the depth dimension of the groove 121 is 1 mm. This is advantageous in reducing the thickness of the electronic apparatus 100 while ensuring the structural strength of the rear case 12.
In some embodiments of the present application, the hooks are plural, and the plural hooks are disposed at intervals in the circumferential direction of the groove 121. Thereby, it is advantageous to further securely confine the electro wetting member 2 within the groove 121.
Further, a plurality of hooks are provided at regular intervals in the circumferential direction of the groove 121. Thereby, it is advantageous to further securely confine the electro wetting member 2 within the groove 121.
According to some embodiments of the present application, the catch is in one piece with the back shell 12. For example, the hook is integrally formed with the rear housing 12. Therefore, the production process is simplified, the production cost is reduced, the connection strength between the clamping hook and the rear shell 12 is improved, and the clamping hook is prevented from being damaged in the long-term use process.
In some embodiments of the present application, in order to further improve the adjustment effect of the electrowetting element 2 on the falling posture of the electronic device 100, the electrowetting element 2 is multiple, and the multiple electrowetting elements 2 are arranged in the thickness direction of the electronic device 100.
Optionally, a plurality of electrowetting elements 2 are connected in parallel. Therefore, when any one of the electrowetting elements 2 is damaged after long-term use, the falling posture of the electronic device 100 can be adjusted by using the other electrowetting elements 2, which is beneficial to further ensuring the adjustment effect of the falling posture of the electronic device 100.
In some embodiments of the present application, the electrowetting element 2 is electrically connected to the control device 7 via the flexible circuit board 3. Specifically, for example, the micro-electrode array 222 and the transparent electrode 212 described above are electrically connected to the control device 7 through one flexible circuit board 3, respectively. Therefore, the connection is convenient and the reliability is high.
In some embodiments of the present application, the electrowetting element 2 has a thickness dimension of 1.5-2.5 mm. For example, the electrowetting element 2 has a thickness of 1.8mm, 2mm or 2.1 mm. Here, it is to be explained that the thickness of the electrowetting element 2 is in the same direction as the thickness of the electronic device 100, i.e. in the above-mentioned direction of separation of the first plate 21 and the second plate 22. Thus, by limiting the thickness dimension of the electrowetting element 2 to within 1.5-2.5mm, on the one hand, the problem of inconvenient mounting and the problem of an increase in the overall thickness dimension of the electronic device 100 due to setting the thickness of the electrowetting element 2 too large is avoided, and on the other hand, the problem of insignificant drop attitude adjustment of the electronic device 100 due to too light weight of the conductive liquid 24 in the electrowetting element 2 due to setting the thickness of the electrowetting element 2 too small is also avoided.
In some embodiments of the present application, the state detection device 6 includes an acceleration sensor and a gyroscope. Therefore, the structure is simple and the cost is low.
Further, the state detection device 6 may further include a magnetic force sensor.
In some embodiments of the present application, the electronic device 100 further includes a storage module, in which a dimension value in a three-dimensional angular coordinate of the electronic device 100 in a target posture in which the electronic device 100 is parallel to a horizontal plane is stored, the state detection device 6 may compare the detected motion state of the electronic device 100 with the target posture, and when the state detection device 6 detects that the electronic device 100 is in a falling state and not in the target posture, the control device 7 applies a voltage to the electrowetting element 2 to adjust the falling posture of the electronic device 100.
