All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The smart watch provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, a schematic structural diagram of a smart watch according to an embodiment of the present application is shown. Referring to fig. 2, a cross-sectional schematic view of the smart watch shown in fig. 1 along one direction is shown. Referring to fig. 3, a cross-sectional schematic view of the smart watch shown in fig. 1 in another direction is shown.
In this embodiment of the application, the smart watch specifically may include: a case 20, a bezel 10 and a position detecting assembly 30; the bezel 10 is disposed on the case 20 and can move or rotate relative to the case 20; the position detecting assembly 30 includes a first electrode plate 31 and a second electrode plate 32, the first electrode plate 31 is disposed on the surface of the bezel 10 opposite to the case 20, the second electrode plate 32 is disposed on the surface of the case 20 opposite to the bezel 10, and the position detecting assembly 30 determines the relative movement information between the bezel 10 and the case 20 according to the capacitance between the first electrode plate 31 and the second electrode plate 32, and triggers the function corresponding to the relative movement information.
In practical applications, the bezel 10 may be a rotatable dial of a smart watch, the case 20 may be a lower dial (or a lower case) of the smart watch, and the bezel 10 may move or rotate relative to the case 20, which may be understood as that the rotatable dial may rotate 360 ° relative to the lower dial, or may move (or be understood as sliding, translating, etc.) in any direction and in a small degree.
In the embodiment of the present application, the relative motion information includes: relative position information, and/or time information; the relative movement information between bezel 10 and case 20 may specifically include: information on the relative position between the bezel 10 and the case 20, and/or information on the time taken for the bezel 10 to rotate or move to the current position of the case 20.
In practical applications, the relative movement information between the bezel 10 and the case 20 may be associated with various functions of the smart watch. For example, in the case where the relative movement information includes only the relative position information, it may be arranged that when the bezel 10 is rotated clockwise by 90 ° with respect to the case 20, the camera of the smart watch is turned on, and then the bezel 10 is turned off counterclockwise by 90 ° with respect to the case 20. Or, when a call comes, the bezel 10 is pushed leftwards, so that the bezel 10 moves leftwards by a small margin relative to the housing 20, and the call is answered, and after the call is ended, the bezel 10 is pushed rightwards, so that the bezel 10 moves rightwards by a small margin relative to the housing 20, and the call is hung up. In the case where the relative movement information includes the relative position information and the time information, it may be further set that: when bezel 10 rotates 90 clockwise and rotates for a long time and be less than 3s relative casing 20, then the camera of intelligent wrist-watch is opened, when bezel 10 rotates 90 clockwise and rotates for a long time and be greater than 3s relative casing 20, then the warning is sent out to the intelligent wrist-watch, reminds the user to confirm whether open the intelligent wrist-watch camera. In practical application, when the bezel 10 rotates clockwise by 90 degrees relative to the case 20 and the rotation time is longer than 3s, the rotation time is longer, which may cause misoperation of a user in the movement process, so that the smart watch can send out actions such as reminding and warning to prevent misoperation. In the embodiment of the application, when the relative motion information comprises the relative position information and the time information, misoperation can be effectively avoided, and the accuracy of function triggering of the intelligent watch is further improved.
In the embodiment of the present application, the time information may be acquired in various ways. For example, a processor within the smart watch may detect the length of time for the bezel to rotate or move through a time detection circuit. In the embodiments of the present application, the manner of obtaining the time information may be the same as that in the prior art, and details thereof are not described in the embodiments of the present application.
In the embodiment of the present application, the following explains, in detail, the determination of the relative position information between the bezel 10 and the case 20 through the capacitance information between the first electrode plate 31 and the second electrode plate 32 by using specific embodiments and application scenarios with reference to the drawings.
In the embodiment of the present application, the first electrode plate 31 may be an uncharged metal plate, that is, in an uncharged state, and the second electrode plate 32 may be a normally-charged metal plate, that is, in a long-distance charged state, because the first electrode plate 31 is opposite to the second electrode plate 32, under the action of the voltage of the second electrode plate 32, charges are accumulated at a position on the first electrode plate 31 opposite to the second electrode plate 32, a potential difference exists between the first electrode plate 31 and the second electrode plate 32, and the first electrode plate 31 and the second electrode plate 32 form a capacitor and have voltages at two ends. In practical applications, when the relative distance, the facing area, and the like between the first electrode plate 31 and the second electrode plate 32 change, the capacitance value (or the voltage value) between the first electrode plate 31 and the second electrode plate 32 also changes, so that when the bezel 10 drives the first electrode plate 31 to rotate or move on the case 20, the relative movement information between the bezel 10 and the case 20 can be determined according to the change of the voltage value between the first electrode plate 31 and the second electrode plate 32, and a corresponding function is triggered. In the embodiment of the application, the position change between the bezel 10 and the housing 20 is detected by using the capacitance sensing principle, and then the corresponding function is triggered, so that the identification precision is high, the controllability is good, and the use experience of a user can be effectively improved.
In practical application, the first electrode plate 31 and the second electrode plate 32 also have the advantages of small size and low cost, so the corresponding smart watch also has the advantages of small size and low cost.
In the embodiment of the present application, one way of achieving the movable connection between bezel 10 and case 20 may be: the watch ring 10 is connected with the casing 20 through a ball shaft, and the ball shaft can rotate 360 degrees, so that the watch ring 10 connected through the ball shaft can rotate 360 degrees or translate along a small amplitude relative to the casing 20.
Optionally, the housing 20 may be provided with a receiving groove 21; the bezel 10 is provided with an accommodating portion 11, the accommodating portion 11 is rotatably disposed in the accommodating groove 21, and/or the accommodating portion 11 is movably disposed in the accommodating groove 21, and the accommodating portion 11 has a first sidewall opposite to a groove wall of the accommodating groove 21, and a gap is formed between the first sidewall and the groove wall of the accommodating groove 21; the first electrode plate 31 is disposed on the first sidewall, and the second electrode plate 32 is disposed on the wall of the accommodating groove 21.
In the embodiment of the present application, first electrode board 31 and second electrode board 32 all set up in holding tank 21 in other words, so both can make the connection of first electrode board 31 and second electrode board 32 walk the line simpler, have also avoided first electrode board 31 and second electrode board 32 to expose the influence that sets up dust steam etc. in leading to receiving the environment, can effectively promote the stability of the voltage that forms between first electrode board 31 and the second electrode board 32, and then promote the recognition accuracy of smart watch.
In practical applications, the accommodating groove 21 may be a cavity for accommodating an electronic device on the smart watch. Specifically, the accommodating groove 21 may be circular or approximately circular. The housing 11 of the bezel 10 may be a portion of the rotatable dial that protrudes into the receiving groove 21. In the case where the receiving groove 21 is circular, the receiving portion 11 may have an annular structure, and the first side wall, i.e., the side wall of the receiving portion 11 opposite to the groove wall of the receiving groove 21, and the gap formed between the groove wall of the receiving groove 21 and the first side wall is annular.
In the embodiment of the present application, the accommodating portion 11 is movably disposed in the accommodating groove 21, and specifically may include: the accommodating portion 11 may be rotatably disposed in the accommodating groove 21, and/or the accommodating portion 11 may be movably disposed in the accommodating groove 21. For example, can set up rotatable dial plate on the smart watch, rotatable dial plate both can carry out 360 rotations, can follow certain direction parallel promotion again or press, and the relative smart watch of rotatable dial plate takes place the small-amplitude removal or the translation down the dial plate, like this, neither can increase the volume of smart watch, can make the structural easier realization of smart watch again, and can also effectively promote user's nature controlled and recreational, promotes user experience.
In practical applications, since the first electrode plate 31 is disposed on the first side wall of the accommodating portion 11, and the second electrode plate 32 is disposed on the wall of the accommodating groove 21, when the accommodating portion 11 rotates in the accommodating groove 21, the relative area between the first electrode plate 31 and the second electrode plate 32 can be changed, which can be simply understood that the first electrode plate 31 can be changed from being opposite to the second electrode plate 32 to not being opposite along with the rotation of the accommodating portion 11, when the first electrode plate 31 and the second electrode plate 32 are opposite to each other, a capacitor is formed, and the voltage is applied between the first electrode plate 31 and the second electrode plate 32, and when the first electrode plate 31 and the second electrode plate 32 are not opposite to each other (misaligned), the capacitor cannot be formed between the first electrode plate 31 and the second electrode plate 32, and the voltage between the first electrode plate 31. Therefore, the relative position of the first electrode plate 31 and the second electrode plate 32 (the first electrode plate 31 and the second electrode plate 32 are opposite or not opposite) and the time length for the first electrode plate 31 to move to the current position can be judged through the voltage values at the two ends of the first electrode plate 31 and the second electrode plate 32, so as to determine the relative motion information between the bezel 10 and the case 20 and trigger the function corresponding to the relative motion information.
In the embodiment of the present application, in order to more accurately position the relative movement information between the bezel 10 and the case 20, that is, the rotation angle and the rotation direction of the bezel 10 relative to the case 20, and/or the moving distance and the moving direction of the bezel 10 relative to the case 20, the number of the second electrode plates 32 may be provided in plural, and the plural second electrode plates 32 are uniformly distributed on the groove wall of the accommodating groove 21 along the circumferential direction of the accommodating portion 11; the first electrode plate 31 is opposite to at least one second electrode plate 32; the smart watch may further include: the processor is respectively connected with the first electrode plate 31 and the second electrode plate 32; under the condition that the accommodating part 11 rotates in the accommodating groove 21, the second electrode plates 32 opposite to the first electrode plates 31 are switched one by one, and the processor is used for determining the rotation angle and the rotation direction of the accommodating part 11 in the accommodating groove 21 according to the capacitance value between the first electrode plates 31 and the second electrode plates 32 and triggering the corresponding functions; in the case that the accommodating part 11 moves in the accommodating groove 21, the first electrode plate 31 is close to or away from the second electrode plate 32 opposite to the first electrode plate 31, and the processor is configured to determine the moving distance and moving direction of the accommodating part 11 in the accommodating groove 21 according to the capacitance values before and after the first electrode plate 31 and the second electrode plate 32 move, and trigger the corresponding functions thereof.
In practical applications, the first electrode plate 31 may be opposite to one or more second electrode plates 32, and the plurality of second electrode plates 32 are uniformly distributed on the wall of the accommodating groove 21 along the circumferential direction of the accommodating portion 11, so that when the accommodating portion 11 rotates in the accommodating groove 21, the first electrode plate 31 rotates along with the accommodating portion 11, and the second electrode plates 32 opposite to the first electrode plate 31 are switched one by one, and the first electrode plate 31 is switched from being opposite to one of the second electrode plates 32 to being opposite to the other second electrode plate 32, that is, the second electrode plates 32 forming a capacitor with the first electrode plate 31 are switched one by one. When the second electrode plate 32 is opposite to the first electrode plate 31, the two ends thereof can detect a voltage, and when the second electrode plate is not opposite to the first electrode plate 31, the two ends thereof do not have a potential difference, and the voltage can be understood as 0. It can be understood that the rotation angle of the accommodating portion 11 is positively correlated with the number of the second electrode plates 32 switched. When one first electrode plate 31 is opposite to one second electrode plate 32, the structure is simple, and the rotation angle and the rotation direction of the accommodating part 11 can be positioned only by judging the position of the second electrode plate 32 generating voltage with the first electrode plate 31. When each first electrode plate 31 is simultaneously opposite to two or more second electrode plates 32, the rotation angle and the rotation direction of the accommodating part 11 can be positioned by simultaneously detecting the voltage between the first electrode plate 31 and the two or more second electrode plates 32 opposite to the first electrode plate 31, so that the accuracy of the rotation angle and the rotation direction of the accommodating part 11 can be effectively improved. In the embodiment of the present application, the position of the second electrode plate 32 generating voltage with the first electrode plate 31 can be detected, so as to determine the rotation angle and the rotation direction of the accommodating portion 11 in the accommodating groove 21, which is simple, fast and accurate in positioning.
Optionally, the number of the first electrode plates 31 is multiple, and each first electrode plate 31 is opposite to at least one second electrode plate 32.
In the embodiment of the present application, the relative positional relationship (the rotation angle and the rotation direction, the movement distance and the movement direction) between the bezel 10 and the case 20 can be determined by detecting the voltage change between each first electrode plate 31 and the plurality of second electrode plates 32 to determine the position of the second electrode plate 32 relative to the first electrode plate 31. In practical applications, in order to improve the accuracy of positioning the relative position relationship between the bezel 10 and the case 20, the number of the first electrode plates 31 may also be set to be plural, and the relative position relationship between the bezel 10 and the case 20 can be determined more accurately by detecting the voltages at two ends of the plural first electrode plates 31 and the plural second electrode plates 32.
Referring to the drawings, the embodiment of the present invention will be described in detail below with reference to a case where one first electrode plate 31 simultaneously faces three second electrode plates 32, and when the bezel rotates relative to the case, the change of the voltage (or capacitance) between the first electrode plate 31 and the plurality of second electrode plates 32 is described.
In the embodiment of the present application, each first electrode plate 31 and the plurality of second electrode plates 32 may form a group of capacitor terminal arrays. In practical application, each capacitor terminal array formed by the first electrode plates and the second electrode plates can be coded, and when the first electrode plates 31 rotate or move along with the bezel 10, the relative position relationship between the bezel 10 and the case 20 can be determined by detecting the change condition of the codes.
Referring to fig. 4, a second schematic structural diagram of the smart watch according to the embodiment of the present application is shown. As shown in fig. 4, the first electrode plate 31 is represented by a1, a2, … … a6, the second electrode plate 32 is represented by b1, b2, b3 … … b10, and the plurality of second electrode plates 32 are sequentially arranged on the groove wall of the accommodating groove 21. In the initial position, the first electrode plate a1 is simultaneously opposite to the second electrode plates b1, b2, and b 3. When the first electrode plate and the second electrode plate are in positive alignment, a capacitor is formed between the first electrode plate and the second electrode plate, and then voltage can be detected at two ends of the capacitor, the reading is recorded as 1, otherwise, the reading is recorded as 0. The readings of the bezel 10 at rest (initial position), one rotation counterclockwise and one rotation clockwise are shown in table 1 below:
as shown in table 1, the corresponding voltage codes when the bezel 10 rotates counterclockwise (or clockwise) by 2 frames and 3 frames … … can be sequentially deduced according to the change rule of the above table. In practical application, the rotation angle of one lattice of clockwise rotation of the bezel 10 can be set to be 5 degrees, the rotation angle of one lattice of counterclockwise rotation of the bezel 10 is set to be-5 degrees, and the rotation angle and the rotation direction of the bezel 10 can be easily obtained according to the change rule of the codes shown in table 1 by measuring the voltages at the two ends of the first electrode plate 31 and the plurality of second electrode plates 32. Obviously, when the bezel 10 rotates relative to the case 20, the voltage change between the first electrode plate 31 and the plurality of second electrode plates 32 can satisfy the first change rule, so that when the voltage at the two ends of the first electrode plate 31 and the plurality of second electrode plates 32 is detected to have the first change rule, it can be obtained that the bezel 10 rotates relative to the case 20, and then the rotation direction and the rotated position of the bezel 10 are deduced according to the change rule of the table 1, which is simple and convenient.
It is understood that, a person skilled in the art may set the angle value corresponding to each rotation of the bezel 10 according to practical situations, and this is not particularly limited in the embodiment of the present application.
The principle of determining the moving direction and the moving distance of the bezel 10 relative to the case 20 in the case of the change of the voltage (or the capacitance) between the first electrode plate and the three second electrode plates opposite to the first electrode plate 31 will be described in detail below with reference to the accompanying drawings by taking the case where one first electrode plate 31 simultaneously faces the three second electrode plates 32 as an example.
Referring to fig. 5, an enlarged view of the position C in fig. 4 is shown. As shown in fig. 5, when the bezel 10 receives the urging force F, the accommodating portion 11 moves in the accommodating groove 21 by the urging force F, and the gap formed between the first side wall and the groove wall of the accommodating groove 21, that is, the distance d between the first electrode plate 31 and the second electrode plate 32 becomes smaller. Since the first electrode plate 31 is opposite to the second electrode plate 32, a capacitor is formed between the first electrode plate 31 and the second electrode plate 32, according to a general formula of the capacitor:
Q＝CU
C＝εS/4πkd
q: the charge quantity of the first electrode plate in the intelligent watch is always kept to be a fixed quantity;
c: a capacitance value of the capacitor;
u: the voltage between two electrode plates (a first electrode plate and a second electrode plate) of the capacitor;
epsilon: the dielectric constant of the medium between the electrode plates, which is air in the present application, can be regarded as a fixed value;
s: the area of the first electrode plate opposite to the area of the second electrode plate is a fixed value;
k: is the constant of the electrostatic force;
d: the distance between the electrode plates, the distance between the first electrode plate and the second electrode plate after receiving the thrust force F, changes, and thus the value changes;
in the embodiment of the present application, U-Q/C-Q4 pi kd/epsilon S, and the voltage U is proportional to the distance d, that is, if the voltage between the electrode plates is detected to be smaller, the distance between the first electrode plate 31 and the second electrode plate 32 after the thrust F is also smaller, and vice versa, that is, the voltage between the electrode plates is positively correlated to the distance between the electrode plates. Therefore, in practical applications, the direction and the moving distance of the accommodating portion 11 subjected to the thrust force F, that is, the moving direction and the moving distance of the bezel 10 relative to the case 20, can be determined by detecting the change in the capacitance value between each first electrode plate 31 and the three second electrode plates 32 opposite thereto.
In the embodiment of the present application, in the case that the number of the second electrode plates 32 is plural, in the plural second electrode plates 32, the energizing voltages of the second electrode plates 32 may be the same or different. The first electrode plate 31 may be a non-charged metal plate, that is, the first electrode plate 31 may be non-charged, and the second electrode plate 32 is long-charged. The principle of the above two schemes is explained in detail below.
In the embodiment of the present application, under the condition that the energization voltages of the plurality of second electrode plates 32 are all the same, the plurality of second electrode plates 32 are uniformly distributed on the groove wall of the accommodating groove 21 along the circumferential direction of the accommodating portion 11, so that the capacitance values of the capacitors formed between the first electrode plate a1 and the second electrode plates b1, b2 and b3 opposite thereto have the same voltage in the default state, and when the first electrode plate a1 rotates along with the accommodating portion 11 in the accommodating groove 21, the rotation direction and the rotation angle thereof can be determined according to the changes in the following table 2. And when the second electrode plate is opposite to the first electrode plate, voltage is formed at two ends of the second electrode plate, the reading is 1, and otherwise, the reading is 0.
Table 2: reading of watch ring in standing, anticlockwise rotating by 1 grid and clockwise rotating by 1 grid
In practical applications, the reading of the voltage between the two plates in table 2 can be used to quickly obtain the change of each capacitance value, and further determine the rotation direction and rotation angle of the accommodating portion (which can also be understood as the rotation direction and rotation stopped position of the first dial).
As shown in fig. 5, when the bezel 10 (the accommodating portion) receives the thrust F and moves in the accommodating groove 21, according to the formula of U/C-Q4 pi kd/e s, since U and d are positive correlations, when the voltage U corresponding to a certain capacitor is detected to have the largest variation, the displacement d of the corresponding movement is the largest, and further, the movement direction and the movement distance of the bezel 10 can be inferred.
In the embodiment of the present application, in the case where the energization voltages of the plurality of second electrode plates 32 are different from each other, the energization voltages of the plurality of second electrode plates 32 may sequentially increase or decrease in the circumferential direction of the accommodating portion. In the embodiment of the present application, the example that the energization voltages of the plurality of second electrode plates 32 are sequentially arranged in a decreasing manner along the counterclockwise direction is described.
Assuming that the charge amounts of the plurality of second electrode plates 32 are, in order, in the counterclockwise direction: b1 ═ b2+ q ═ b3+2q ═ … … ═ bx + (x-1) q; where q represents an electric quantity, x represents the number of the second electrode plates 32, and the larger x, the lower its detection accuracy. B1, b2 and b3 voltages corresponding to a1 are U1, b4, b5 and b6 voltages corresponding to a2 are U2, and so on, quantized sampling is performed according to U1, U2 and U3 … … Ux, for example, the quantized sampling is 8 bits, and then binary representation is:
U1＝00000001
U2＝00000010
U3＝00000011
…
expressed in decimal system, Ux is x;
in practical applications, each second electrode plate 32 has a specific voltage value, and when the bezel 10 drives the first electrode plate 31 to rotate, the capacitance value of the capacitor formed between the corresponding second electrode plate 32 changes, that is, the voltage values at the two ends of the first electrode plate 31 and the second electrode plate 32 change. When the bezel 10 rotates the first electrode plate 31, the voltage of the second electrode plate 32 changes as shown in table 3, and the changes are sequential. The voltage codes at the two ends of the first electrode plate and the second electrode plate are read when the watch ring 10 is in a standing state, rotates anticlockwise for 1 grid and rotates clockwise for 1 grid as shown in table 3.
As shown in table 3When the voltage value on the second electrode plate 32 side changes according to the above rule, it is determined that the bezel 10 rotates, and the rotation angle and the rotation direction of the bezel 10 relative to the case 20 can be obtained according to the change of the specific voltage value of the second electrode plate 32. When the voltage value on the second electrode plate 32 side changes irregularly, it is determined that the bezel 10 moves relative to the case 20, and it is assumed that the voltage of the second electrode plate 32 is changed from the default state U0＝Q/C＝Q4πkd0Change of/ε S to U1＝Q/C＝Q4πkd1S,/epsilon S, due to U1/U0＝d1/d0D due to default state0Is the same, therefore, when the U of the second electrode plate is among them1/U0＝d1/d0When the value is the largest, it can be determined that the bezel 10 has the largest displacement at the position corresponding to the second electrode plate, and further, it can be determined that the movement direction and the movement distance of the bezel 10 relative to the case 20 have occurred.
In the embodiment of the present application, in order to further improve the accuracy of detecting the relative position relationship between the bezel 10 and the case 20, the plurality of first electrode plates 31 may be symmetrically disposed on the first side wall in pairs. In practical application, when bezel 10 moves relative to case 20, the distance between two first electrode plates 31 that the symmetry set up respectively and its corresponding second electrode plate 32 changes the same, therefore, can be through the capacitance change of two electrode plates of the above-mentioned symmetry of simultaneous detection to promote the degree of accuracy that intelligent wrist-watch position detected.
Hereinafter, the case of simultaneously detecting the capacitance change of two electrode plates that are symmetrical will be explained in detail with reference to the accompanying drawings.
Referring to fig. 6, a schematic diagram of the displacement change of the bezel in the embodiment of the present application is shown. As shown in fig. 6, a1 represents the position of case 20, a2 represents the position after bezel 10 has been moved by a pushing force, A3 represents the initial position (default state/position at rest) of bezel 10, B1 represents the first electrode plate, B2 represents the second electrode plate facing B1, and d01、d02Representing the distance between the first electrode plate and the second electrode plate at the initial position; d11、d12Indicating the distance between the first electrode plate and the second electrode plate after being pushed, when the bezel is at the initial position, U01＝Q4πkd01/εS，U02＝Q4πkd02ε S; after the watch ring moves under the thrust, the U11＝Q4πkd11/εS，U12＝Q4πkd12ε S; at this time, the left and right side displacement variation can be calculated as follows: d1＝d01-d11＝(U01-U11)εS/Q4πk，D2＝d12–d02＝(U12-U02) ε S/Q4 π k. In the embodiment of the application, the first electrode plates are symmetrically arranged in pairs, so that the first electrode plates can pass through the electrode plates D1＝D2And the detection of the two data can effectively improve the position detection accuracy.
In practical application, different displacement thresholds (rotation direction and rotation angle, movement direction and movement distance) can be set for different scene applications, so that operability and entertainment of the intelligent watch are improved. For example, it may be set that when the displacement of the bezel 10 from the initial position to one side is detected to be greater than a certain threshold, the incoming call is regarded as the answering action, and when the displacement from the initial position to the direction opposite to the answering action is detected to be greater than a certain threshold, the incoming call is regarded as the rejecting action.

in the embodiment of the present application, since the bezel is disposed on the case and can move or rotate relative to the case, and since the first electrode plate is disposed on the surface of the bezel opposite to the case, and the second electrode plate is disposed on the surface of the case opposite to the bezel, when a capacitor can be formed between the first electrode plate and the second electrode plate, a voltage is applied to two ends of the first electrode plate and the second electrode plate. In practical application, when the relative distance, the facing area and the like between the first electrode plate and the second electrode plate are changed, the capacitance value or the voltage value between the first electrode plate and the second electrode plate is changed, so that when the watch ring drives the first electrode plate to move on the shell, the relative movement information between the watch ring and the shell can be determined according to the change of the voltage value between the first electrode plate and the second electrode plate, and the corresponding function is triggered. In the embodiment of the application, utilize the capacitance induction principle, detect the position change between bezel and the casing, and then trigger corresponding function, not only the recognition accuracy is high, but also the controllability is better, can effectively promote user to use experience.
The embodiment of the application also provides an interaction method which is applied to the intelligent watch. Referring to fig. 8, a flowchart illustrating steps of an interaction method according to an embodiment of the present application is shown, which may specifically include the following steps:
Specifically, the position relationship between the first electrode and the second electrode in the position detection assembly in the smart watch may refer to the above-mentioned embodiment of the smart watch, and details are not repeated here.
In the embodiment of the present application, the first state and the second state may respectively indicate that the bezel is located at different positions of the case. For example, the first capacitance value in the first state may represent a capacitance value between the first electrode plate and the second electrode plate when the bezel is in the initial state, or may represent a capacitance value between the first electrode plate and the second electrode plate when the bezel rotates or moves to a certain position; the second capacitance value in the second state may be represented as a capacitance value between the first electrode plate and the second electrode plate when the bezel rotates or moves from the position of the first state to the position of the second state. In the embodiment of the present application, each of the first state and the second state may be an intermediate state in which the bezel is rotated or moved to a certain position of the case. In practice, the relative positions of the bezel and the case in the first and second states may be the same or different.
For example, when the bezel rotates clockwise for one grid, the capacitance between the first electrode plate and the second electrode plate may be a first capacitance in the first state, and the bezel continues to rotate until the bezel rotates clockwise for three grids, at this time, the capacitance between the first electrode plate and the second electrode plate may be a second capacitance in the second state, if the bezel continues to rotate, the second capacitance in the second state may continue to be recorded as a first capacitance in the next first state, and then when the bezel continues to rotate to the next position, the capacitance between the first electrode plate and the second electrode plate may be taken as a second capacitance in the second state. That is to say, in the embodiment of the present application, when the bezel is located at any position, the capacitance value between the corresponding first electrode plate and the corresponding second electrode plate can be both recorded as a first capacitance value in the first state or a second capacitance value in the second state.
In the embodiment of the application, when the first capacitance value in the first state and the second capacitance value in the second state are obtained, time information used for converting the first capacitance value in the first state to the second capacitance value in the second state can be obtained synchronously, and then different functions can be triggered correspondingly according to the rotation speed of the bezel.
In the embodiment of the present application, the relative movement information between the bezel and the case may include relative position information, or, relative position information and time information. For example, when the bezel is in the initial position, the capacitance between the first electrode plate and the second electrode plate can be denoted as a first capacitance in the first state, and when the bezel is shifted leftward by the distance d, the capacitance between the first electrode plate and the second electrode plate can be denoted as a second capacitance in the second state. In practical application, the time for the bezel to translate by the distance d from the initial position can be synchronously acquired, and then different functions are determined and triggered according to three technical parameters, namely the first capacitance value in the first state, the second capacitance value in the second state and the translation time.
Optionally, the step of determining the relative movement information between the bezel and the case according to the first capacitance value and the second capacitance value may specifically include: determining that the bezel rotates when the change of the second capacitor relative to the first capacitor meets a first preset rule; determining the rotation direction and the rotation angle of the bezel according to the change value of the second capacitor relative to the first capacitor; or, determining that the bezel moves when the change of the second capacitance relative to the first capacitance meets a second preset rule; and determining the moving direction and the moving distance of the bezel according to the change value of the second capacitor relative to the first capacitor.
In the embodiment of the present application, taking an example that one first electrode plate directly faces three second electrode plates, along the clockwise direction, 8 second electrode plates are selected as a group to be encoded, when the first electrode plate and the second electrode plate are directly opposite, they form a capacitor, there is a potential difference between both ends to detect voltage, the reading is recorded as 1, otherwise, the reading is recorded as 0, taking the three second electrode plates directly opposite to the first electrode plate as the initial position, and the reading of the bezel when standing (initial position), rotating counterclockwise by one grid, and rotating clockwise by one grid is as shown in the following table 4:
as shown in table 4, when the bezel rotates, the second electrode plates directly opposite to the first electrode plate are switched one by one, so that the change of each code group is regular, that is, only when the bezel is aligned with the first electrode plate, the voltage reading is recorded as 1, otherwise, the voltage reading is zero. Therefore, in practical application, when the second capacitance value is detected to have the change rule relative to the first capacitance value, the watch ring can be judged to rotate relative to the shell, and then the rotation direction and the rotation angle of the watch ring can be obtained according to the change rule. When the bezel moves, for example, the bezel translates relative to the case, since the second electrode plate directly opposite to the first electrode plate does not change, and only the distance between the first electrode plate and the second electrode plate changes, the voltage detected by the second electrode plate opposite to the first electrode plate, that is, the voltage reading is still recorded as 1, that is, when the bezel translates relative to the case, the code value is unchanged, and the second change rule, that is, the code does not change.
In practical application, when it is detected that the voltage code corresponding to the second capacitance value does not change relative to the voltage code corresponding to the first capacitance value, it can be determined that the bezel has moved (translated) relative to the case, and then the displacement distance and the displacement direction of the bezel are respectively calculated according to a general formula Q ═ CU, C ═ S/4 π kd of the capacitance. Specifically, the displacement distance and the displacement direction of the bezel are calculated according to the above formula, which can refer to the above embodiments and will not be described herein again.
In the embodiment of the application, multiple functions can be correspondingly set according to the difference of the rotating direction and the rotating angle of the bezel relative to the shell, or multiple functions can be correspondingly set according to the difference of the moving distance and the moving direction of the bezel relative to the shell. In addition, the processor of the intelligent watch can be used for detecting the time when the bezel rotates or moves relative to the shell, and when the bezel rotates or moves relative to the shell, the rotation or movement time can be set to be different, and the corresponding functions are different. Therefore, the intelligent watch can be controlled by utilizing the principle of capacitance induction and in a rotating or pushing mode, the operational interest of the intelligent watch is enhanced, meanwhile, the control mode is enriched, and the defect that a display screen does not sense when a touch screen swims underwater can be overcome, or the intuitiveness of control during map navigation is improved.
