[0036] Some embodiments of the present disclosure will be described in detail with reference to the drawings, of which examples are shown. The following description, in relation to the drawings, refers to the same or similar elements using the same or similar reference numerals unless otherwise indicated. The implementations described in the following description of some embodiments of the present disclosure are not meant to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] Wearable devices have various style types, such as business style, casual style, sports style, and so on. However, due to the difference in style, the same wearable device cannot be adapted to all occasions, and the user can only replace the wearable device that is adapted to the occasion in a new occasion, which is extremely inconvenient.

[0038] The existing wearable device is designed with a detachable shell. Different magnetic pieces are arranged in different shells, and a magnetic sensitive sensor is arranged in the wearable device main body to detect the magnetic field of the magnetic piece. The magnetic piece is identified to identify the shell, so as to control the display interface of the wearable device to change to the interface adapted to the shell. In this way, by replacing the shell with different styles, the style of the wearable device can be adapted to various occasions. However, the existing wearable device shell is only provided with a simple magnetic piece, and the magnetic sensitive sensor detects the north and south poles of the magnetic piece to identify the type of the shell. In this way, the number of shell types is small, and the type of style change of the wearable device is small.

[0039] To solve the above technical problems, the present disclosure provides a wearable device. A plurality of magnets are arranged in a frame ring which is detachably arranged in a frame area of the wearable device, and a magnetic detection device is arranged in the frame area. The magnetic detection device includes a plurality of magnetic sensitive sensors which have a corresponding relationship with the positions of the magnets when the frame ring is assembled with the frame area. When the frame ring is assembled with the frame area, a control device determines the type of the frame ring based on the magnetic induction strength array sensed by the magnetic detection device, and controls the display interface of the wearable device to change accordingly. The present disclosure can arrange a plurality of magnets with different magnetic induction strength combinations in the frame ring, so that the frame ring has a plurality of types. The display interface, function, configuration, and the like of the wearable device can be adjusted based on the type of the frame ring, so as to enhance the interest and practicality of the wearable device, and improve the user experience.

[0040] An example embodiment of the present disclosure provides a wearable device, which is described with reference to Figures 1 to 4As shown, the wearable device 100 can include a smart watch, a smart bracelet, smart glasses, and the like electronic device that a user can wear on the body. In the following, the smart watch is taken as an example of the wearable device 100 to exemplarily illustrate the embodiments of the present disclosure. It should be noted that the wearing fixing device and the like structure of the wearable device 100 are omitted in the drawings in the present disclosure, and only the bezel ring 10, the bezel area 20, the device main body 30, the magnetic detection device 40, the display interface 50, and the like of the wearable device 100 related to the technical content of the present disclosure are illustrated.

[0041] The wearable device 100 includes the bezel ring 10, which can be in a ring shape. The bezel ring 10 is detachably arranged with the bezel area 20, which is in a ring shape and arranged radially outward of the wearable device 100. The bezel area 20 is the edge area of the device main body 30 of the wearable device 100. The bezel area 20 can be arranged in a groove shape to fix and accommodate the position of the bezel ring 10 when the bezel ring 10 is assembled in the bezel area 20. The bezel ring 10 and the bezel area 20 can be detachably assembled by, for example, a spring sheet, a buckle, and the like. The bezel ring 10 can be used to protect the core components of the watch. When the bezel ring 10 is assembled in the bezel area 20 of the wearable device 100, the bezel ring 10 can play a role of impact resistance, and can also cover the bezel area 20 to play a role of waterproofing and the like. In addition, since the bezel ring 10 can be provided with design elements such as a time scale and a scale, the style, color, and the like of the bezel ring 10 can also be designed based on the needs of the user, and the bezel ring 10 can also play a decorative role for the wearable device 100. It can be understood that when the wearable device 100 includes a smart watch, the bezel ring 10 can include a watch ring or a watch case.

[0042] A plurality of magnets 11 can be arranged in the bezel ring 10. The magnet 11 is a substance or material capable of generating a magnetic field. The magnet 11 can be, for example, a permanent magnet capable of maintaining magnetism for a long time. The material of the magnet 11 can include, but is not limited to, high-carbon steel, alnico magnet, samarium-cobalt magnet, ferrite magnet, neodymium-iron-boron magnet, and the like. The magnet 11 can be accommodated in the bezel ring 10, or the magnet 11 can be mounted on the side of the bezel ring 10 facing the bezel area 20, so that the user can observe the complete surface of the bezel ring 10, and the arrangement of the magnet 11 will not damage the appearance design of the bezel ring 10.

[0043] The number of magnets 11 in the bezel 10 is not limited in the present disclosure, for example, it can be 2, 3, 4, 5, etc. The plurality of magnets 11 can be arranged along the annular shape of the bezel 10. It can be understood that, in order to reduce the interference of the magnetic field between adjacent magnets 11, when the plurality of magnets 11 is arranged on the bezel 10, there is a certain interval between adjacent magnets 11, or the interval distance between adjacent magnets 11 is equal. Taking the bezel 10 as an annular ring for example, when two magnets 11 are arranged on the bezel 10, the connecting line between the two magnets 11 can pass through the axis 12 of the bezel 10, that is, the two magnets 11 can be arranged at the positions farthest away from each other on the bezel 10. For another example, when three magnets 11 are arranged on the bezel 10, the included angle between adjacent magnets 11 around the axis 12 of the bezel 10 can be 120°, so that the adjacent magnets 11 have the same and larger interval distance.

[0044] In some examples, with reference to Figures 3 to 5 When a plurality of magnets 11 is arranged in the bezel 10, the included angle α between adjacent two magnets 11 around the axis 12 of the bezel 10 can be a preset included angle α, which can be an included angle at which the mutual interference of the magnetic field between adjacent magnets 11 is lighter, so that the magnetic sensitive sensor 41 in the magnetic detection device 40 can accurately sense the magnetic induction intensity of the magnet 11 corresponding to its position. For example, through a large number of experiments, the preset included angle α between adjacent magnets 11 around the axis 12 of the bezel 10 can be greater than or equal to 35°, for example, it can be 35°, 36°, 40°, 45°, etc., so as to reduce the mutual interference of the magnetic field between adjacent magnets 11. Based on the preset included angle α between adjacent magnets 11, up to ten magnets 11 can be arranged in the annular bezel 10.

[0045] With reference to Figure 2 , Figure 4 and Figure 5 The magnetic detection device 40 of the wearable device 100 is arranged in the bezel area 20 of the wearable device 100, for example, arranged inside the bezel area 20, and the material of the bezel area 20 covers and protects the magnetic detection device 40. The magnetic detection device 40 is used to detect the magnetic field generated by the magnet 11 on the bezel 10. For example, the magnetic detection device 40 can include a plurality of magnetic sensitive sensors 41, and the number of magnetic sensitive sensors 41 can be the same as the number of magnets 11 arranged on the bezel 10. The arrangement mode of the plurality of magnetic sensitive sensors 41 in the bezel area 20 is the same as the arrangement mode of the magnet 11 in the bezel 10, so that when the bezel 10 and the bezel area 20 are assembled, the positions of the magnetic sensitive sensor 41 and the magnet 11 have a corresponding relationship, so that the magnetic sensitive sensor 41 can sense the magnetic induction intensity of the magnet 11.

[0046] In some examples, the positional correspondence between the magnetic sensor 41 and the magnet 11 can be misaligned, i.e., the magnetic sensor 41 and the magnet 11 are staggered in the thickness direction of the wearable device 100, and there is a certain distance between the magnetic sensor 41 and the magnet 11. In the case where the magnetic sensor 41 can detect the magnetic induction intensity of the magnet 11, the thickness of the wearable device 100 can be reduced to improve the portability of the wearable device 100. In other examples, the positional correspondence between the magnetic sensor 41 and the magnet 11 can also be aligned, i.e., the magnetic sensor 41 and the magnet 11 are aligned in the thickness direction of the wearable device 100, which can improve the accuracy of the magnetic sensor 41 in detecting the magnetic induction intensity of the magnet 11. Figure 4 and Figure 5 In the case where the positional correspondence between the magnetic sensor 41 and the magnet 11 is aligned, the magnetic sensor 41 and the magnet 11 are aligned in the thickness direction of the wearable device 100, which can improve the accuracy of the magnetic sensor 41 in detecting the magnetic induction intensity of the magnet 11.

[0047] When the frame ring 10 is assembled with the frame area 20, since the magnets 11 have a certain arrangement in the frame ring 10, when each magnetic sensor 41 senses the magnetic induction intensity of the magnet 11, the magnetic sensor 41 can sense the comprehensive magnetic induction intensity reaching its sensing range due to the magnetic field information released by the plurality of magnets 11. Since the positions of different magnetic sensors 41 in the frame area 20 are different, the magnetic induction intensity of the magnet 11 sensed by each magnetic sensor 41 is also different. Therefore, the control device can receive the magnetic induction intensity array output by the magnetic detection device 40 including the plurality of magnetic sensors 41, so as to identify different types of frame rings 10.

[0048] Exemplarily, the magnetic induction intensity sensed by the magnetic sensor 41 is a physical quantity for characterizing the strength and direction of the magnetic field of the magnet 11, and the magnetic induction intensity is a vector. Therefore, it should be noted that the magnetic induction intensity of the magnet is the same only when the strength of the magnetic field of the magnet is the same and the direction of the magnetic field is the same. When the strength of the magnetic field of two magnets is the same, but the direction of the magnetic field is opposite, the magnetic induction intensity of the two magnets is also different.

[0049] Exemplarily, the magnetic sensor 41 capable of sensing the magnetic induction intensity can include a Hall sensor, a fluxgate sensor, a magnetoresistance sensor, etc. The Hall sensor is a sensor designed based on the Hall effect. When a magnet is close to a conductive plate with current, the magnetic field of the charge carriers in the conductive plate is distorted, thereby disturbing the straight flow of the charge carriers. The negatively charged electrons will be deflected to one side of the plate, and the positively charged holes will be deflected to the other side of the plate, thereby generating a potential difference between the two sides of the plate, i.e., a Hall voltage. The Hall voltage measured by the Hall sensor appears in a direction orthogonal to both the current and the direction of the magnetic field. Therefore, the Hall voltage can feedback the information of the direction and strength of the magnetic field of the magnet close to the Hall sensor, i.e., the magnetic induction intensity of the magnet.

[0050] The fluxgate sensor is an instrument for sensing an external magnetic field by using the electromagnetic induction phenomenon of a soft magnetic core with high permeability under the action of an external magnetic field. The fluxgate sensor includes a magnetic core made of a material with high permeability and easy saturation, and an excitation coil and a signal coil formed around the magnetic core. Under the magnetization of an alternating excitation signal, the magnetic permeability characteristics of the magnetic core change periodically between saturation and non-saturation, so that the signal coil around the magnetization induces an induced signal proportional to the external magnetic field. The even harmonics in the induced signal can feedback the information of the magnetic field direction and the magnetic field strength of the external magnetic field, i.e., the magnetic induction intensity of the external magnetic field.

[0051] The magnetoresistive sensor is a sensor designed based on the magnetoresistance effect. The resistance value of the magnetic material in the magnetoresistive sensor changes with the strength and direction of the external magnetic field. By measuring the change in resistance, the magnetic field direction and the magnetic field strength of the external magnetic field are fed back, i.e., the magnetic induction intensity of the external magnetic field.

[0052] In some examples, the magnetic sensor 41 is arranged opposite to the magnet 11, so that when the bezel ring 10 and the bezel area 20 are assembled, each magnetic sensor 41 can sense the magnetic induction intensity of the magnet 11 corresponding to its position. When the magnetic induction intensities of the plurality of magnets 11 arranged on different bezel rings 10 are different, the magnetic sensor 41 can sense the magnetic induction intensity of the magnet 11 corresponding to its position, so that the magnetic detection device 40 outputs different magnetic induction intensity arrays, and the control device can recognize different types of bezel rings 10.

[0053] Reference Figure 2 , Figure 4 and Figure 5 The wearable device 100 further includes a control device (not shown in the figure), which can be a device integrated with data storage and data processing, for example, can include a processor and a memory. The control device is connected with the magnetic detection device 40, for example, can be electrically connected or communicatively connected, so that when the bezel ring 10 and the bezel area 20 of the wearable device 100 are assembled, the magnetic induction intensity array formed by the magnetic induction intensity of the magnet 11 corresponding to the position of each magnetic sensor 41 in the magnetic detection device 40 can be transmitted to the control device. The control device can recognize the type of the bezel ring 10 assembled on the bezel area 20 based on the obtained magnetic induction intensity array.

[0054] It should be noted that since the array refers to a sequence of multiple data of the same type arranged in a certain order, the magnetic induction strength array includes multiple magnetic induction strengths arranged in a certain order. In this way, for the same set of magnets 11, when the placement positions of the magnets 11 in the frame ring 10 are different, the ordering sequence of the multiple magnetic induction strengths in the magnetic induction strength array is different, and then the magnetic induction strength array sensed by the magnetic detection device 40 is also different, thereby increasing the number of types of frame rings 10 that the control device can identify. For example, when two magnets 11 are arranged in the frame ring 10, for two magnets 11 with magnetic induction strengths of +70T and -30T respectively, based on the different placement positions of the magnets 11 in the frame ring 10, the magnetic induction strength array sensed by the magnetic detection device 40 can be (+70T, -30T) or (-30T, +70T), thereby setting two different types of frame rings 10. Wherein, T (Tesla) is the unit of magnetic induction strength, and the symbols "+" and "-" only represent the direction of the magnetic field generated by the magnet 11, and do not represent the positive and negative of the value.

[0055] Reference Figure 3 , Figure 4 and Figure 5 , based on the different magnetic induction strengths of the magnets 11 arranged in the frame ring 10 and the different placement positions of the magnets 11, to distinguish a plurality of different types of frame rings 10. Different types of frame rings 10 can be one or more of different materials, shapes, colors, styles, logos, patterns, etc. So that when the user assembles different types of frame rings 10 in the frame area 20, the control device can determine the type of the frame ring 10 based on the magnetic induction strength array sensed by the magnetic detection device 40, and control the display interface 50 of the wearable device 100 to change to adapt to the frame ring 10 assembled on the wearable device 100. Exemplarily, the control device can control the display interface 50 of the wearable device 100 to change and change one or more of the text style, text color, background pattern style, background pattern color, decoration pattern style, decoration pattern color, interface layout, interface theme, icon shape, etc. in the display interface 50 based on the type of the frame ring 10, so that the appearance effect presented in the display interface 50 adapts to the frame ring 10, thereby changing the style and appearance presented by the wearable device 100 to the user, so that the wearable device 100 can adapt to various scenes.

[0056] Since the magnetic sensor 41 in the present disclosure can sense the magnetic induction intensity of the magnet 11 corresponding to its position, and the control device determines the type of the bezel ring 10 based on the magnetic induction intensity array output by the magnetic detection device 40. By setting the magnets 11 in the bezel ring 10 that can generate different magnetic field directions, different magnetic field strength degrees, and setting the magnets 11 at different positions in the bezel ring 10, so that the magnetic detection device 40 can sense a large number of magnetic induction intensity arrays, thereby satisfying that a large number of types of bezel rings 10 can be set to improve the style variability of the wearable device 100. When the user needs to change the style of the wearable device 100, the user only needs to replace the bezel ring 10 to get a wearable device 100 that can provide a completely new appearance effect, improve the interest and practicality of the wearable device 100, and also reduce the cost of the user to get a wearable device 100 with a completely new appearance effect, improve the user's experience and satisfaction.

[0057] In some possible implementations, with reference to Figure 3 , Figure 4 and Figure 5 , since the volume of the wearable device 100 is small, the size of the bezel ring 10 is limited, and the size of the magnet 11 arranged on the bezel ring 10 is also limited, therefore, although the material and the saturation degree of magnetization of the magnet 11 can be changed, for the magnet 11 with limited size, the magnetic induction intensity of the magnet 11 is also within a limited range. In some examples, the magnetic induction intensity of the magnet 11 is within a preset interval, which is determined based on the size and material of the magnet 11. Exemplarily, when the size of the magnet 11 is determined, the magnetic induction intensity of the magnet 11 made of the material with the maximum magnetism and magnetized to the oversaturation degree is taken as the maximum value B max of the preset interval. Of course, it can be understood that since the magnet 11 has magnetism, the magnetic induction intensity of the magnet 11 should be greater than 0, therefore, the preset interval can be represented as (0, B max ]. Further, in order to avoid the magnetism of the magnet 11 disappearing over time, the minimum value of the preset interval can be a larger value greater than 0, for example, it can be 10, 20, etc., and the preset interval can be represented as [B min , B max ].

[0058] It should be noted that since the magnetic induction intensity is a physical quantity used to represent the strength and direction of the magnetic field of the magnet 11, for different magnets 11 in terms of the direction of the magnetic field, the magnetic induction intensity thereof is within the preset interval. Since the magnet 11 has two magnetic poles, i.e., a south pole and a north pole, and the magnetic induction lines around the magnet 11 are all from the south pole to the north pole, the magnetic induction intensity of the magnet 11 is obtained by sensing the magnetic field around the magnet 11, and therefore, the symbol "+" can be used to represent the south pole magnetic field of the magnet 11, and the symbol "-" can be used to represent the north pole magnetic field of the magnet 11. Therefore, for the preset interval of the magnetic induction intensity of the magnet 11, it can include a preset interval of the magnetic induction intensity generated by the south pole magnetic field of the magnet 11, and a preset interval of the magnetic induction intensity generated by the north pole magnetic field of the magnet 11.

[0059] In the preset interval, the magnetic induction intensity of different magnets 11 can have a preset interval, which can be a magnetic induction intensity value that avoids sensing errors of the magnetic sensor 41. In some examples, the range of the preset interval can be 15T-25T, for example, it can be 15T, 16T, 18T, 20T, 23T, 24T, 25T, etc., to avoid the situation that the magnetic sensor 41 senses the magnetic induction intensity of the magnets 11 with different magnetic field strengths, and the values of the magnetic induction intensity obtained by the magnets 11 are the same, so that the control device recognizes the type of the bezel ring 10 and errors occur.

[0060] When the magnetic induction intensity of the magnet 11 is within the preset interval, and the magnetic induction intensity of the magnet 11 has a preset interval, it can be determined that the magnet 11 can have a first preset number n of kinds of magnetic induction intensity, which can be considered that the bezel ring 10 can be provided with a first preset number n of different types of magnets 11. For example, when the preset interval of the magnetic induction intensity of the magnet 11 is [20T, 80T], and the preset interval is 20T, based on the different magnetic poles of the magnet 11 close to the magnetic sensor 41, the magnetic induction intensity of the magnet 11 provided in the bezel ring 10 can be ±20T, ±40T, ±60T, and ±80T. That is, when the preset interval of the magnetic induction intensity of the magnet 11 is [20T, 80T], and the preset interval is 20T, the magnet 11 has a first preset number eight of kinds of magnetic induction intensity in the preset interval, and the bezel ring 10 can be provided with eight magnets 11 with different magnetic induction intensities. In this example, the numerical value is only used for example illustration, and cannot be regarded as a limitation of the actual embodiment.

[0061] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5The magnetic induction intensity array sensed by the magnetic detection device 40 can be different based on the placement position of the magnets 11 in the bezel ring 10. When the number of magnets 11 arranged in the bezel ring 10 is the second preset number r, from the first preset number of types n of magnets 11, the second preset number r of magnets 11 can be taken out each time, and the magnets 11 with the same magnetic induction intensity can be repeatedly taken out and arranged in a row as a repeatable arrangement. For a repeatable arrangement, the arrangement order of different types of magnets 11 in the bezel ring 10 is the same as the arrangement mode of different types of magnets 11 in the repeatable arrangement. That is, a repeatable arrangement can determine an arrangement mode of the magnets 11 in the bezel ring 10, and thus can determine a type of the bezel ring 10. Then, from the first preset number of types n of different magnets 11, the second preset number r of magnets 11 can be taken out each time, and the types of magnets 11 are allowed to appear repeatedly, and the number of repeatable arrangements formed is the number of types of the bezel ring 10 that can be arranged.

[0062] Exemplarily, the number of types of the bezel ring 10 can be denoted as wherein n represents the number of types of magnetic induction intensity of the magnets 11 that can be selected in the preset interval, that is, the first preset number of types, and r represents the number of magnets 11 arranged in the bezel ring 10, represents the total number of repeatable arrangements formed by taking out r magnets 11 each time from n different magnets 11 and allowing the types of magnets 11 to appear repeatedly, that is, the number of types of the bezel ring 10 that can be arranged.

[0063] For example, when the preset interval of the magnetic induction intensity of the magnets 11 is [20T, 80T] and the preset interval is 20T, the magnets 11 have a first preset number of types n = 8 of magnetic induction intensity in the preset interval. When the second preset number of magnets 11 in the bezel ring 10 is r = 2, the two magnets 11 in the bezel ring 10 can have n r = 8 2 = 8x8 = 64 types of arrangement modes, that is, 64 different types of bezel rings 10 can be arranged. When the second preset number of magnets 11 in the bezel ring 10 is r = 3, the three magnets 11 in the bezel ring 10 have n r = 8 3 = 8x8x8 = 512 types of arrangement modes, that is, 512 different types of bezel rings 10 can be arranged. In this example, the numerical values are only used for example and cannot be used as a limitation of the actual embodiments.

[0064] It can be understood that the reference Figure 3 , Figure 4 and Figure 5Since the size of the magnet 11 is limited, the preset range of the magnetic induction intensity of the magnet 11 is also limited, and the first preset number of categories of the magnet 11 in the preset range is also small, therefore, the number of magnets 11 arranged in the frame ring 10 can be increased to increase the number of types of frame rings 10 that can be arranged, and the selectability of the user can be increased. At the same time, the number of magnetic sensors 41 in the magnetic detection device 40 needs to be increased to increase the number of magnetic induction intensity arrays sensed by the magnetic detection device 40, so that the control device can identify more types of frame rings 10, and control the display interface of the wearable device 100 to change accordingly based on the type of the frame ring 10.

[0065] In some examples, referring to Figure 2 , Figure 4 and Figure 5 , based on the positions of the magnetic sensors 41 on the bezel area 20, the plurality of magnetic sensors 41 can be numbered in the magnetic detection device 40. For example, the magnetic sensor 41 closest to the crown (not shown in the figure) can be numbered one, and the plurality of magnetic sensors 41 can be numbered in the clockwise direction as the first sensor, the second sensor, and so on; or in the counterclockwise direction as the first sensor, the second sensor, and so on. In this way, the plurality of magnetic induction intensities sensed by the plurality of magnetic sensors 41 are sequentially arranged to obtain a magnetic induction intensity array. For example, the plurality of magnetic induction intensities in the magnetic induction intensity array are sequentially arranged based on the number of the magnetic sensors 41, which can be arranged from small to large based on the number, or from large to small based on the number, and so on. In this way, the magnetic induction intensity array sensed by the magnetic detection device 40 can reflect the arrangement of the plurality of magnets 11 on the frame ring 10, and the type of the frame ring 10 is one-to-one corresponding to the magnetic induction intensity array sensed by the magnetic detection device 40, thereby ensuring that the control device can accurately identify the type of the frame ring 10.

[0066] In some examples, referring to Figure 4 and Figure 5When the frame ring 10 is assembled with the frame area 20, the magnet 11 is vertically opposite to the position of the magnetic sensor 41 on the frame area 20, and when the magnet 11 is assembled with the frame ring 10, the magnetization direction of the magnet 11 is the same as the extension direction of the axis 12 of the frame ring 10. The magnetization direction is the orientation direction of the applied magnetic field when the magnet 11 is magnetized to obtain magnetism, and the magnetization direction can reflect the positions of the south pole and the north pole in the magnet 11. In this way, when the magnet 11 is assembled with the frame ring 10, the magnetization direction of the magnet 11 is axial, that is, the south pole or the north pole of the magnet 11 can be vertically opposite to the magnetic sensor 41. For the magnet 11 with the same magnetism, when the south pole or the north pole of the magnet 11 is vertically opposite to the magnetic sensor 41, the magnetic field at the pole of the magnet 11 is the strongest, so that the magnetic sensor 41 can obtain the maximum magnetic induction intensity, and the sensing sensitivity of the magnetic sensor 41 is improved. In this way, when the number of types of the frame ring 10 is large, the magnetic detection device 40 can accurately sense the magnetic induction intensity of the magnet 11 in each type of the frame ring 10, and the control device can accurately identify the type of the frame ring 10.

[0067] For example, when the preset interval of the magnetic induction intensity of the magnet 11 is [20T, 80T] and the preset interval is 20T, the magnetic induction intensity of the magnet 11 can be ±20T, ±40T, ±60T and ±80T respectively according to different positions of the magnet 11 close to the pole of the magnetic sensor 41. When the magnet 11 is assembled with the frame ring 10, the magnetization direction of the magnet 11 is axial, that is, the magnetization direction is the same as the extension direction of the axis of the frame ring 10, and the magnetic induction intensity sensed by the magnetic sensor 41 is close to the real magnetic induction intensity of the magnet 11. Since there is a certain distance between the magnet 11 and the magnetic sensor 41, the actual magnetic induction intensity sensed by the magnetic sensor 41 corresponding to the position of the magnet 11 can be ±15T, ±35T, ±55T and ±75T respectively, and the magnetic sensor 41 can accurately identify the type of the magnet 11 in the frame ring 10, so that the control device can accurately identify the type of the frame ring 10.

[0068] However, when the magnet 11 is assembled with the frame ring 10, the magnetization direction of the magnet 11 is radial, that is, the magnetization direction of the magnet 11 is perpendicular to the axis of the frame ring 10, and the magnetism of the middle region of the magnet 11 and the side surface of the magnet 11 is small. For the magnet 11 with a real magnetic induction intensity of 80T, the actual magnetic induction intensity sensed by the magnetic sensor 41 can be only 30T-40T, and for the current structure of the wearable device 100, the type of the magnet 11 that can be identified by the magnetic sensor 41 will be reduced, and the control device can not accurately identify the type of the frame ring 10.

[0069] In some examples, with reference to Figure 2 , Figure 4 and Figure 5 , the magnetic sensitive sensors 41 in the magnetic detection device 40 can include 3D Hall sensors, which can sense the magnetic field in three-dimensional directions of X-axis, Y-axis and Z-axis with the position of the magnetic sensitive sensors 41 as the origin, and output the magnetic induction intensity sensed by the X-axis, Y-axis and Z-axis respectively.

[0070] The Z-axis of the 3D Hall sensor is the first detection axis in the same direction as the axis 12 of the frame ring 10, that is, the Z-axis of the 3D Hall sensor can be configured to sense the magnetic induction intensity of the magnet 11 corresponding to its position. Since the magnetization direction of the magnet 11 is the same as the direction of the axis 12 of the frame ring 10 when the magnet 11 is assembled in the frame ring 10, and the magnet 11 and the position of the magnetic sensitive sensor 41 are vertically opposite, the magnetic induction intensity Bz output by the Z-axis of each 3D Hall sensor is the magnetic induction intensity of the magnet 11 corresponding to its position, to form a magnetic induction intensity array.

[0071] Since multiple magnets 11 can be arranged in the frame ring 10, and the degree of electrification in the wearable device 100 is high, when the Z-axis of the 3D Hall sensor senses the magnetic field of a certain magnet 11 corresponding to its position, the magnetic field of other magnets 11 in the frame ring 10 or the magnetic field generated by the operation of electronic components may interfere with the magnetic field of the magnet 11, causing the magnetic induction intensity Bz sensed by the Z-axis of the 3D Hall sensor corresponding to the position of the magnet 11 to deviate from the true magnetic induction intensity of the magnet 11. That is, the magnetic induction intensity Bz sensed by the Z-axis of the 3D Hall sensor can be the magnetic induction intensity after superposition of multiple magnetic fields, and the magnetic induction intensity deviates, which is easy to cause the control device to misidentify the type of the frame ring 10.

[0072] Since the magnetization direction of the magnet 11 is parallel to the Z axis of the 3D Hall sensor, and the X axis and Y axis of the 3D Hall sensor also sense the surrounding magnetic field, the X axis and Y axis can only weakly sense the magnetic field of the magnet 11 corresponding to the position of the 3D Hall sensor, but the X axis and Y axis can sense the magnetic field of other magnets 11 in the bezel ring 10 and the magnetic field generated by the electrical components in the wearable device 100. Therefore, the X axis and Y axis of the 3D Hall sensor can be configured to sense the environmental magnetic field information around the 3D Hall sensor, and Bx and By can be obtained, respectively. In some examples, Bx and By sensed by the X axis and Y axis can be used to compensate Bz sensed by the Z axis, so that the Bz output by the Z axis of the 3D Hall sensor approaches the true magnetic induction intensity of the magnet 11 corresponding to the position of the 3D Hall sensor, thereby reducing the probability of misidentifying the type of the bezel ring 10 by the control device, or avoiding misidentifying the type of the bezel ring 10 by the control device. When Bx and By sensed by the X axis and Y axis are used to compensate Bz sensed by the Z axis, for example, a compensation coefficient can be calculated based on the linear relationship between Bx, By and Bz output by the X axis, Y axis and Z axis, to compensate Bz sensed by the Z axis.

[0073] It should be noted that when the magnetic sensor 41 is a 3D Hall sensor, the magnetization direction of the magnet 11 is still set to be the same as the extension direction of the axis of the bezel ring 10, i.e., the magnetization direction of the magnet 11 is axial, so that when the bezel ring 10 is assembled in the bezel area 20, the magnetic pole of the magnet 11 is in a position directly opposite the 3D Hall sensor, and the Bz output by the Z axis of the 3D Hall sensor approaches the true magnetic induction intensity of the magnet 11. If the magnetization direction of the magnet 11 is radial, the X axis or Y axis of the 3D Hall sensor is used to sense the magnetic induction intensity of the magnet 11, however, the sensing of the X axis or Y axis is more affected by the external environmental magnetic field than the sensing of the Z axis, and the magnetic induction intensity output by the X axis or Y axis deviates greatly; secondly, when the bezel ring 10 is assembled in the bezel area 20, the magnet 11 cannot be directly opposite the 3D Hall sensor, and the magnet 11 is in a relatively parallel state with the 3D Hall sensor, the X axis or Y axis can only sense the magnetic induction line on one side of the magnet 11, and the magnetic induction intensity output by the X axis or Y axis is much lower than the true magnetic induction intensity of the magnet 11. Based on the above two reasons, the magnetization direction of the magnet 11 is set to be axial, and the magnetic sensor 41 identifies more types of magnets 11, so that the control device can identify more types of bezel rings 10.

[0074] In one example embodiment, the present disclosure provides a control method of a wearable device, which can be applied to the control device of the wearable device provided in the above-mentioned embodiments of the present disclosure, and with reference to the Figure 6 The control method of the wearable device includes the following steps:

[0075] Step S100: When the frame ring of the wearable device is assembled with the frame area of ​​the wearable device, obtain the magnetic induction intensity array corresponding to the multiple magnets on the frame ring;

[0076] Step S200: Determine the type of the border ring based on the magnetic induction intensity array;

[0077] Step S300: Based on the type of the bezel, control the display interface of the wearable device to change accordingly.

[0078] In step S100, refer to Figures 1 to 5 As shown, since the bezel ring 10 of the wearable device 100 is detachably connected to the bezel area 20 of the wearable device 100, the user can remove the original bezel ring 10 from the bezel area 20 and assemble a new bezel ring 10 with the bezel area 20. Since each bezel ring 10 is provided with multiple magnets 11, a magnetic detection device 40 can be installed in the bezel area 20. The magnetic detection device 40 can include multiple magnetic sensors 41, which can include Hall sensors, fluxgate sensors, magnetoresistive sensors, 3D Hall sensors, and other devices capable of sensing the strength and direction of a magnetic field.

[0079] When the frame ring 10 of the wearable device 100 is assembled with the frame area 20 of the wearable device 100, the position of the magnet 11 on the frame ring 10 can correspond to the position of the magnetic sensor 41 on the frame area 20. This positional correspondence can be, for example, staggered; in the thickness direction of the wearable device 100, the magnetic sensor 41 and the magnet 11 are not directly opposite each other, but are staggered, with a certain distance between them. Since multiple magnets 11 release magnetic field information, each magnetic sensor 41, when sensing the magnetic induction intensity of a magnet 11, can sense the combined magnetic induction intensity within its sensing range, thereby outputting a magnetic induction intensity. Because different magnetic sensors 41 are located in different positions within the frame area 20, each magnetic sensor 41 senses a different magnetic induction intensity of the magnet 11. Multiple magnetic induction intensities can be arranged in a certain order, forming a magnetic induction intensity array, which is the magnetic induction intensity array corresponding to the multiple magnets 11 output by the magnetic detection device 40. The magnetic detection device 40 can be connected to the control device of the wearable device. The magnetic detection device 40 can transmit the magnetic induction intensity array to the control device so that the control device can obtain the magnetic induction intensity array.

[0080] In other examples, the positional correspondence between the magnetic sensor 41 and the magnet 11 can be that they are positioned vertically opposite each other, as shown in the reference. Figure 4 and Figure 5In the thickness direction of the wearable device 100, the magnetic sensor 41 is positioned directly opposite the magnet 11. The magnetic sensor 41 can sense the magnetic flux density of the magnet 11 corresponding to its position. The magnetic flux density data of multiple magnets 11 sensed by multiple magnetic sensors 41 can be arranged in a certain order to form a magnetic flux density array output by the magnetic detection device 40. The magnetic detection device 40 can be connected to the control device of the wearable device, and can transmit the magnetic flux density array to the control device so that the control device can acquire the magnetic flux density array.

[0081] In step S200, refer to Figures 1 to 5 As shown, since the bezel 10 is detachable from the wearable device 100, various types of bezels 10 can be provided for users to choose from, thereby changing the appearance of the wearable device 100. Different types of bezels 10 can differ in one or more elements such as material, shape, color, style, logo, and pattern. Furthermore, different types of bezels 10 may contain magnets 11 with different magnetic induction intensities, or the magnets 11 may be positioned differently within the bezel 10, ensuring that for each type of bezel 10, the magnetic induction intensity array formed by the ordered magnetic induction intensities of multiple magnets 11 is unique. Thus, when the bezel 10 is mounted on the bezel area 20, the control device can determine the type of bezel 10 based on the magnetic induction intensity array transmitted by the magnetic detection device 40.

[0082] In some possible implementations, step S200, determining the type of the border ring based on the magnetic induction intensity array, includes:

[0083] Step S210: Obtain configuration information. The configuration information is used to characterize the correspondence between the magnetic induction intensity array and the type of the bounding ring.

[0084] Step S220: Determine the type of the border ring corresponding to the magnetic induction intensity array based on the configuration information and the magnetic induction intensity array.

[0085] In this embodiment, reference Figures 1 to 5 As shown, the configuration information is used to characterize the correspondence between the magnetic induction intensity array and the type of the frame ring 10. The configuration information can be pre-set in the memory of the wearable device 100. Since the magnetic induction intensity array formed by the magnetic induction intensity of multiple magnets 11 in each type of frame ring 10 is unique, the magnetic induction intensity array corresponding to each type of frame ring 10 can be sensed and recorded before the wearable device 100 leaves the factory, and a correspondence can be formed with the type of frame ring 10, so as to form configuration information stored in the memory of the wearable device 100.

[0086] After acquiring the magnetic induction intensity array, the control device indicates that the frame ring 10 has been assembled on the frame area 20 of the wearable device 100. The control device can retrieve the configuration information in the memory, traverse the target magnetic induction intensity array that is completely consistent with the current magnetic induction intensity array in the configuration information, and determine the type of the frame ring 10 corresponding to the target magnetic induction intensity array, which is the type of the frame ring 10 assembled on the frame area 20.

[0087] Understandably, the configuration information can use names like Type 1, Type 2, etc., to distinguish different types of bezels 10, and the configuration information can detail the material, shape, color, style, logo, pattern, and other information of each type of bezel 10. Of course, the configuration information can also store the settings of the display interface 50 corresponding to each type of bezel 10, so that after the control device identifies the type of bezel 10, it can control the display interface 50 of the wearable device 100 to adapt to the bezel 10.

[0088] In step S300, refer to Figures 1 to 5 As shown, the control device can control the display interface 50 of the wearable device 100 to change accordingly based on the type of the border ring 10. For example, the control device can replace and change one or more elements in the display interface 50, such as text style, text color, background pattern style, background pattern color, decorative pattern style, decorative pattern color, interface layout, interface theme, and icon shape, so that the appearance of the display interface 50 is adapted to the border ring 10, thereby changing the style and appearance presented to the user by the wearable device 100, making the wearable device 100 adaptable to various scenarios. For each type of border ring 10, the wearable device 100 can pre-store the design elements of the display interface 50 corresponding to each type of border ring 10, so that after the control device determines the type of border ring 10, it can further control the display interface 50 of the wearable device 100 to change.

[0089] For example, when the watch dial is circular, the display area of the display interface 50 is circular by default. When the inner ring of the bezel ring 10 with a polygonal shape is assembled with the wearable device 100, the display area of the display interface 50 can be set to be polygonal to adapt to the shape of the inner ring of the bezel ring 10, so as to avoid that part of the patterns or characters in the display interface 50 are blocked by the bezel ring. For another example, when the bezel ring 10 with a metal material is assembled with the wearable device 100, the background pattern of the display interface 50 can be set to have a metal texture, for example, the color of the background pattern is changed to silver white, silver gray, black gray and the like with a metal texture. For another example, when the bezel ring 10 with a plastic material and a color is assembled with the wearable device 100, the background color of the display interface 50 can be set to adapt to the color of the bezel ring 10, and the interface theme is replaced by a theme of a sports and leisure style, and the like. For another example, when the bezel ring 10 with a vehicle logo is assembled with the wearable device 100, the decoration pattern of the display interface 50 is set to be a vehicle, the color of the vehicle can be the same as the color of the bezel ring 10, and the interface theme is replaced by a vehicle theme, and the like.

[0090] Since the wearable device provided by the above-mentioned embodiments of the present disclosure has a large number of types of bezel rings, the user can replace the bezel ring based on the use demand, so that the wearable device can adapt to various scenes and improve the practicability of the wearable device. Meanwhile, the various types of bezel rings can also increase the interest of the wearable device and improve the user experience.

[0091] In some possible implementation manners, in the process of implementing the step S100, i.e., when the bezel ring of the wearable device is assembled with the bezel area of the wearable device, before the magnetic induction intensity array is acquired, the control method of the wearable device further includes:

[0092] The step S101 detects the magnetization direction of the magnet, and determines whether the magnetization direction of the magnet is the same as the extension direction of the axis of the bezel ring.

[0093] In the step S100, the magnetic induction intensity array is acquired, including:

[0094] When it is determined that the magnetization direction of the magnet is the same as the extension direction of the axis of the bezel ring, the magnetic induction intensity array is acquired.

[0095] In the embodiment, the magnetic induction intensity array is acquired by the following steps. Figures 1 to 5As shown, due to the complex magnetic field environment around the magnetic sensor 41, when the frame ring 10 is placed beside the wearable device 100 before the frame ring 10 is assembled in the frame area 20, or when the wearable device 100 is in a strong magnetic environment, the magnetic sensor 41 in the magnetic detection device 40 can also sense certain magnetic field information, and the magnetic detection device 40 can also output a magnetic induction intensity array including multiple magnetic induction intensities. In this way, it is easy to cause the control device to misidentify, and the user's experience is not high.

[0096] Since the magnetization direction of the magnet 11 in the frame ring 10 is the same as the extension direction of the axis 12 of the frame ring 10, when the frame ring 10 is assembled with the frame area 20 of the wearable device 100, the magnetization direction of the magnet 11 in the frame ring 10 can be detected by the magnetic sensor 41 in the magnetic detection device 40 first, and after it is determined that the magnetization direction of the magnet 11 is the same as the extension direction of the axis 12 of the frame ring 10, the magnetic detection device 40 obtains the magnetic induction intensity array. In this way, on the one hand, it can be ensured that the magnetic sensor 41 senses the magnetic field of the magnet 11 after the frame ring 10 is assembled in the frame area 20, avoiding mis-sensing of the magnetic sensor 41; on the other hand, this method can identify whether the frame ring 10 is a fake counterfeit product, avoiding the type of the frame ring 10 not matching the changed display interface 50 controlled by the control device subsequently, or avoiding the display interface 50 not changing accordingly after the user replaces the frame ring 10.

[0097] Exemplarily, since the magnetization direction of the magnet 11 in the frame ring 10 is the same as the extension direction of the axis 12 of the frame ring 10, and the position of the magnet 11 and the position of the magnetic sensor 41 can be arranged vertically opposite, during the assembly of the frame ring 10 and the frame area 20 of the wearable device 100, the distance between the magnetic pole of the magnet 11 and the magnetic sensor 41 gradually decreases, and the value of the magnetic induction intensity sensed by the magnetic sensor 41 gradually increases as the distance between them decreases. That is, during the assembly of the frame ring 10 and the frame area 20 of the wearable device 100, when the values of the magnetic induction intensities sensed by the multiple magnetic sensors 41 all show a linear increasing trend, it can be determined that the magnetization direction of the magnet 11 in the frame ring 10 is the same as the extension direction of the axis 12 of the frame ring 10.

[0098] After the frame ring 10 and the frame area 20 are assembled, the maximum value of the magnetic induction intensity in the linear curve corresponding to each magnetic sensor 41 can be taken as the magnetic induction intensity of the magnet 11 corresponding to the position of the magnetic sensor 41. The multiple magnetic induction intensities are sorted in a predetermined manner as the magnetic induction intensity array output by the magnetic detection device 40 and transmitted to the control device.

[0099] It should be noted that when the magnetic sensor 41 is set as a 3D Hall sensor, in the process of assembling the frame ring 10 and the frame area 20 of the wearable device 100, when the magnetic induction intensity value output by the first sensing axis (i.e. Z axis) of the 3D Hall sensor in the same direction as the axis 12 of the frame ring 10 gradually increases linearly as the distance between the magnet 11 and the magnetic sensor 41 gradually decreases, and the magnetic induction intensity values sensed by the X axis and Y axis of the 3D Hall sensor remain basically unchanged, it can be determined that the magnetizing direction of the magnet 11 in the frame ring 10 is the same as the extension direction of the axis 12 of the frame ring 10.
