DETAILED DESCRIPTION

[0062] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0063] Figure 1 This is a schematic diagram of an application scenario involved in this application, where a wearable device is worn on a user's wrist. Currently, the tightness of the wearable device is manually adjusted by the user, which reduces the accuracy of health monitoring.

[0064] In view of the above problems, the inventors found in the process of studying this field that by using a conductor as the main body of the magnetic strap of a wearable device, when the bracelet or watch is measuring health data, the transmission current inside the strap is increased to enhance the magnetic force between the internal structures of the strap, thereby achieving automatic contraction of the strap. After the data detection is completed, the current inside the strap decreases, the magnetic force weakens accordingly, and the strap returns to a relaxed state.

[0065] The watchband control method of the present application can be used in wearable devices such as smart watches and smart bracelets.

[0066] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0067] Figure 2 This is a flow chart of Embodiment 1 of the method for controlling a watch strap provided in the present application, as shown in FIG. Figure 2 As shown, the method includes:

[0068] S101. Acquire strap contraction information, where the strap contraction information includes a health data measurement identifier and / or a strap tension value.

[0069] In some embodiments, a tension sensor is provided between the strap and the dial, and the strap tension value data in the tension sensor needs to be acquired in real time.

[0070] In some embodiments, the strap contraction information includes a health data measurement identifier, that is, when the user selects a health item to be measured on the watch body, the health data measurement identifier is obtained, and different health measurement items have different identifiers.

[0071] In some embodiments, both the health data measurement identifier and the strap tension value are obtained.

[0072] S102: Determine a target current according to the strap contraction information.

[0073] Whether the contraction condition is met is determined based on the strap contraction information. The contraction condition is receiving a user's request to start health data measurement (i.e., receiving a health data measurement identifier), and / or detecting that the tension value of the strap is greater than a preset value.

[0074] When any contraction condition is met, subsequent operations are triggered.

[0075] If the contraction condition is met, a target current under the contraction condition is obtained, and the target current is greater than an initial current when the strap is initially worn.

[0076] Under different contraction conditions, the current in the corresponding strap is determined in different ways, and the resulting current value is also different. Therefore, it is necessary to determine which contraction condition is met.

[0077] If it is detected that the user turns on the health data measurement and meets the contraction condition, the identifier of the health data measurement turned on by the user is obtained. Different identifiers correspond to different measurement items, and different measurement items pre-set different current values ​​in the strap. The first mapping relationship includes the current corresponding to each health data measurement identifier. Therefore, a unique target current can be determined according to the health data measurement identifier. Obtain the health data measurement identifier;

[0078] Exemplarily, the health data measurement items set in the smart wearable device include heart rate measurement, sleep measurement, blood oxygen measurement, etc., and different items correspond to different current values.

[0079] If the tension value of the strap is detected to be greater than a preset value and the contraction condition is met, the tension value in the tension sensor is obtained, and different tension value intervals are preset to correspond to different current values. The second mapping relationship includes the current corresponding to each tension range, so a unique target current can be determined according to the tension value.

[0080] When the watch strap is initially worn, the initial current is determined according to the user's settings. The initial current may be 0, that is, there is no current, and the watch strap is worn relying on mechanical force.

[0081] In some embodiments, if it is detected that the user turns on health data measurement and the pulling force value is greater than a preset value, it is considered that the user needs health data measurement, and the target current is determined based on the health data measurement identifier.

[0082] S103, setting the current in the watchband as a target current, wherein the watchband includes two groups of conductors, and the force generated by the target current input into the two groups of conductors causes the watchband to contract.

[0083] In this step, conductors are provided in the watch strap. After the target current is input into the watch strap, one group of conductors will generate a magnetic field to act on the other group of conductors. By setting the direction of the current, the direction of the action between the two groups of conductors can be controlled, so that the two conductors generate a force of mutual attraction, so that the two groups of conductors are brought closer together and the watch strap shrinks.

[0084] How to set two groups of conductors in the watch strap will be introduced in the subsequent embodiments.

[0085] The present embodiment provides a method for controlling a watchband, wherein two groups of conductors are arranged in the watchband. When current is passed through the two groups of conductors, a force is generated to cause the watchband to contract. Therefore, when the contraction condition is met, a target current is determined according to the contraction condition, and the target current is input into the watchband to cause the watchband to contract.

[0086] Based on the above embodiment, when the contraction condition ends, that is, when the health data measurement started by the user ends, or the detected tension value changes from greater than a preset value to less than a preset value, the current in the strap is set to the initial current.

[0087] During daily use, users may need to adjust the tightness of the initial wearing state. The following is an introduction on how to adjust the tightness of the initial wearing state using an embodiment.

[0088] Figure 3 The flowchart of the second embodiment of the control method of the watch strap provided by the present application is as follows: Figure 3 As shown, the method includes:

[0089] S201. In response to a user's operation of adjusting an initial wearing contraction gear, an initial contraction gear is obtained.

[0090] In this solution, different contraction gears are pre-set in the watch, and the user selects the required initial contraction gear on the watch screen.

[0091] S202: Determine a new initial current according to the initial contraction gear.

[0092] Different contraction gears correspond to different initial current values, so the new initial current can be determined according to the initial contraction gear.

[0093] S203, setting the current in the strap to a new initial current.

[0094] Through this embodiment, the user can adjust the initial contraction state of the watchband to meet the user's needs by selecting the required contraction gear and adjusting the initial current in the watchband.

[0095] The following two examples introduce the strap retraction control method.

[0096] Example 1

[0097] Figure 4 This is a flow chart of an embodiment of a method for controlling a watch strap provided in the present application. Figure 4 As shown, the method includes:

[0098] S301. The user measures health data.

[0099] S302, presetting different sensors and different strap retraction positions.

[0100] In this step, different sensors are preset in the watch to measure different health data, and different strap retraction positions are set according to different health data measurement indicators.

[0101] S303: The user selects the item to be measured.

[0102] S304: Determine whether the test item requires the strap to be retracted.

[0103] Some pre-configured test items do not require the strap to be retracted, that is, the strap can be in the initial retracted position without changing the current in the strap. Therefore, whether the strap needs to be retracted is determined according to the test item.

[0104] If contraction expression is required, execute step S305.

[0105] If contraction expression is not required, execute step S307.

[0106] S305, increasing the internal current of the strap, and shrinking the strap to a corresponding gear position.

[0107] S306: The strap is retracted and the measurement of health data begins.

[0108] S307: Measurement ends.

[0109] S308: Reduce the internal current of the watch strap and restore the default wearing position.

[0110] In this step, after the measurement is completed, the current in the strap is reduced to the initial current value, that is, the default wearing position is restored.

[0111] Through this example, when the user measures health data, the current in the strap is changed to shrink the strap, which can make the watch fit better and improve measurement accuracy.

[0112] Example 2

[0113] When the user puts on or takes off the strap, the strap will be subjected to external tension. A tension sensor is set between the strap and the dial to measure the tension value. Determine whether the tension value exceeds the critical value. If it exceeds the critical value, increase the current inside the strap to shrink the strap. Continue to determine whether the tension value exceeds the critical value. If it is detected that the tension value does not exceed the critical value, adjust the current inside the strap to the initial current and the strap returns to normal.

[0114] Through the method of this example, when the strap is subjected to a large tensile force, resistance is automatically generated to prevent the device from falling off, thereby improving the safety and stability of wearing.

[0115] Several embodiments are used below to introduce the arrangement of the conductor inside the watchband to implement the above-mentioned watchband contraction control method.

[0116] Watchband structure embodiment 1

[0117] The strap includes two sets of conductors, a current input interface and a current output interface.

[0118] Each set of conductors is wrapped with an insulating sleeve, and the currents of the two sets of conductors flow in the same direction horizontally. The current-carrying wires can generate a magnetic field around them. Because the currents of the two sets of conductors flow in the same direction horizontally, the other set of current-carrying wires is acted upon by the Ampere force in the magnetic field, generating a force that can shrink the watch strap.

[0119] For example, Figure 5 The structure of the strap provided for this application Figure 1 ,like Figure 5 As shown, the watch strap includes: one group of conductors is AC, the other group of conductors is DC, the current input interfaces are A and D, and the current output interface is C, wherein the ends of the conductors are fixed on the insulating layer on the outside of the watch strap. A linking hub is provided between the two conductors at C, that is, the two conductors are fixed together, which can be mechanically fixed, wire harness fixed, etc., which are not limited here. The insulating sleeve wrapped around the outside of each group of conductors is not shown in the figure, and the ends of the conductors are fixed on the insulating layer on the outside of the watch strap.

[0120] exist Figure 5 Multiple groups of conductors are shown, including another pair of two groups of conductors BC and FC, which together form a group of contraction structures.

[0121] When the strap needs to be retracted, a current is passed through the strap in the direction shown in the figure. When the conductor AC is passed with current, the conductor AC will generate a magnetic field. When the conductor CD is passed with current as shown in the figure, according to Ampere's screw law, under the magnetic field generated by the conductor AC, CD will be subjected to a force diagonally upward to the left. According to the action and reaction force, or according to the magnetic field generated by DC, AC will be subjected to a force diagonally downward to the left. Similarly, BC will be subjected to a force diagonally downward to the right due to the magnetic field generated by the conductor FC; FC will be subjected to a force diagonally upward to the right due to the magnetic field generated by the conductor BC. An overall analysis shows that because the two groups of conductors attract, the distance between the two groups of conductors becomes smaller, thereby achieving the effect of contraction.

[0122] Figure 5 In the figure, two conductor lines are arranged side by side in each conductor group, which increases the magnetic field near the conductor and can also superimpose electromagnetic forces to increase the contraction effect. In some other methods, a single conductor line layout method or a plurality of conductor line layout methods can also be adopted.

[0123] It should be noted that the magnitudes of the currents between the two groups of conductors may be the same or different.

[0124] The electromagnetic force between the two sets of conductors is:

[0125]

[0126] Where μ is the vacuum magnetic permeability, I1 is the current in one set of conductors, I2 is the current in the other set of conductors, and d is the effective distance between the two conductors. To solve the effective distance, the average distance between the two conductors can be used instead, or the force at each position can be solved by integration.

[0127] Figure 6 The structure of the strap provided for this application Figure 2 ,like Figure 6 As shown, multiple groups of Figure 5 Similar contraction structure improves the contraction effect inside the strap.

[0128] exist Figure 6 The number of contraction structures in the strap is affected by the length of the strap and the distance between the two contraction structures, and the distance between the two contraction structures is not limited. Separating the two groups of contraction structures can also avoid the influence of each other's magnetic fields.

[0129] Figure 7 The structure of the strap provided for this application Figure 3 ,like Figure 7 As shown, multiple groups of Figure 5Similar contraction structures improve the contraction effect inside the strap, and the two sets of contraction structures coincide with the connection points outside the strap, forming a chain structure that can serve as the supporting body of the entire strap.

[0130] exist Figure 7 In the connection method shown, in order to avoid the magnetic force consumption generated by the two contraction structures, it is necessary to control the current direction, such as Figure 7 As shown, the magnetic field generated by the current in DE is the same as the magnetic field generated by AC in the CD space, so there is a superposition effect, which will increase the force F on CD. According to the force analysis, there is an upward component in the force generated by ED on DC, and DC generates a downward component of force on ED, and the force between ED and EG is shown in the figure, and the two are also mutually attractive. The force analysis of EF and EH will not be repeated. According to the above force analysis, after power is turned on, there is a trend of decreasing distance between point A and point D, and there is a trend of decreasing distance between point D and point G, which can achieve a contraction effect.

[0131] At this time, the position of point E is the current input point of the multiple conductor structures in a group of contraction structures.

[0132] In one implementation, Figure 7 In the layout method in , the currents of AC, FC, ED, and EH are greater than the currents of other conductor segments.

[0133] Figure 8 The structure of the strap provided for this application Figure 4 ,like Figure 8 As shown, two sets of conductors are arranged in parallel. Figure 5 It can be seen from the formula in the embodiment that, compared with the inclined placement, this arrangement can maximize the distance between the two wires and maximize the magnetic force of attraction between them.

[0134] There is mutual attraction between the two groups of conductors to shorten the distance between the conductors. When setting other conductor structures, it is necessary to avoid interference with the magnetic force, or to increase the magnetic force by setting the current direction.

[0135] Fig. 9 The structure of the strap provided for this application Figure 5 In the figure, the distance between the two conductors AB and DF is in the order of millimeters. The other set of abdf contraction structures should be away from the ABDF contraction structure, otherwise the current in ab will cause the conductor ab to attract DF and weaken the force between AB and DF. Therefore, the two need to be separated by a certain distance.

[0136] In another way, you can also not take the distance approach, Fig.10 The structure of the strap provided for this application Figure 6 ,like Fig.10As shown, the current of the second group of contraction structures is opposite to that of the first group of contraction structures. In this way, DF and ab repel each other, increasing the contraction effect between the two groups of conductors in one group of contraction structures. The contraction structures in the strap are sequentially set with opposite currents.

[0137] It should be noted that there is a fixed support between D and a in the strap, and the distance between them will not change, while there is no fixed support between a and d, and the distance between them can be changed by force.

[0138] Based on the above embodiments, according to the current flow direction preset in the conductor, when the strap needs to be retracted, the retraction can be achieved by determining the preset value of each group of conductors according to the preset mapping relationship.

[0139] Due to the limitation of the safety voltage of the wearable device, the maximum current in the device is also limited. Therefore, the magnetic field generated by the conductor current is limited, and the contraction force generated is also limited. In order to increase the contraction effect, a magnetic field device is added to the conductor, such as a permanent magnet or an electromagnet. The magnetic field of the electromagnet or permanent magnet can be adjusted in advance, so the direction of the magnetic field can be set as needed in the subsequent embodiments.

[0140] Fig.11 The structure of the strap provided for this application Figure 7 ,exist Figure 7 In the figure, the magnetic field device is marked with a magnet. The magnet is set between two sets of conductor structures and fixed on the watch strap. After power is turned on, the Ampere force brings the two closer together to achieve a contraction effect.

[0141] For adjacent contraction structures, magnets such as Fig.11 In the arrangement shown, the magnetic fields generated by the two magnets can be superimposed, thereby increasing the effect of the Ampere force and enhancing the contraction effect.

[0142] The magnetic device mentioned above can be arranged in any of the above-mentioned strap embodiments to enhance the magnetic field and the contraction effect.
