Description

Technical Field

[0001] This application relates to the field of wearable device technology, and more particularly to a crown assembly, a watch body, and a wearable device. Background Technology

[0002] Smartwatches are gaining increasing attention due to their small size, diverse communication functions, and stylish appearance. Smartwatches include a mechanism that detects the movement of the crown. To ensure functionality, this mechanism and other components of the smartwatch must be waterproofed, placing high demands on its waterproofing and resulting in a complex and multifaceted waterproofing system. Summary of the Invention

[0003] This application provides a crown assembly, a watch body, and a wearable device. This application enables effective detection of crown movement and achieves waterproofing of the magnetic detection element, with minimal and simple waterproofing components.

[0004] In a first aspect, embodiments of this application provide a crown assembly applied to a watch body, the watch body including a magnetic detection element. The crown assembly includes an outer frame, a waterproof component, a crown, and a magnetic component. The waterproof component is fixed to the inner wall of the outer frame, the waterproof component and a first frame body of the outer frame forming a first cavity, the waterproof component and a second frame body of the outer frame forming a second cavity, the second cavity being used to install the magnetic detection element, and the waterproof component preventing water from entering the second cavity from the first cavity. The crown includes a crown cap and a crown rod, the crown cap being located outside the outer frame, a first end of the crown rod being fixedly connected to the crown cap, a second end of the crown rod extending into the first cavity, and the magnetic component being fixed to the second end.

[0005] The movement of the crown drives the movement of the magnetic component, and the change in the magnetic field of the magnetic component affects the output signal of the magnetic detection component to detect the movement of the crown.

[0006] This embodiment of the application uses a magnetic component fixed to the second end of the crown. A magnetic detection component detects the crown's movement by sensing changes in the magnetic field of the magnetic component at its location. This magnetic detection design allows detection to be achieved even when the magnetic component and the magnetic sensor are in different spaces. By placing the magnetic component in the first cavity and the magnetic sensor in the second cavity, a waterproof component isolates the magnetic component and the magnetic sensor in different spaces, providing waterproof protection for the magnetic sensor. By placing the waterproof magnetic sensor in the second cavity, there is no need for waterproofing the first cavity, and no waterproof structure is required between the crown stem and the first frame, resulting in a simpler and less complex waterproofing structure. During crown movement, the waterproof component remains stationary, meaning its position relative to the outer frame is fixed. This ensures high reliability and stability of the waterproof component, and provides excellent waterproofing for the magnetic sensor with a high waterproof rating.

[0007] In one possible implementation, the first frame and the second frame enclose a mounting cavity, wherein the first cavity is part of the mounting cavity and the second cavity is another part of the mounting cavity. Isolating the mounting cavity into a first cavity and a second cavity using a waterproof component facilitates the installation of necessary structural components within the first and second cavities as required.

[0008] In one possible implementation, the waterproof component includes a first surface and a second surface, with the first surface facing the first cavity and the second surface facing the second cavity. The second surface is used to fix the magnetic detection component. By fixing the magnetic detection component to the second surface of the waterproof component, the distance between the magnetic detection component and the magnetic component is closer, enabling accurate acquisition of the magnetic field changes of the magnetic component at the location of the magnetic detection component, thus improving detection accuracy. In other embodiments, the magnetic detection component and the waterproof component can also be arranged alternately, that is, the magnetic detection component is not located on the second surface of the waterproof component. This application does not limit this aspect.

[0009] In one possible implementation, the second surface is provided with a groove for mounting the magnetic sensor. By positioning the magnetic sensor within the groove, the space occupied by the magnetic sensor and the waterproof component in the mounting cavity of the crown assembly can be reduced, which is beneficial for the miniaturization of wearable devices, and the waterproof component can protect the magnetic sensor.

[0010] In one possible implementation, the central axis of the crown, the central axis of the magnetic component, and the central axis of the magnetic detection component are collinear. This embodiment of the application, by setting the central axes of the magnetic detection component, the magnetic component, and the crown to be collinear, makes the detection of the crown more accurate and simpler, avoiding the need for the wearable device system to correct the collected data when the central axes of the magnetic detection component, the magnetic component, and the crown are not collinear.

[0011] In one possible implementation, the magnetic poles of the magnetic component are arranged along the extending direction of the crown, or the magnetic poles are arranged in a direction perpendicular to the extending direction of the crown. Arranging the magnetic poles along the extending direction of the crown allows for the detection of crown pressing; arranging them perpendicular to the extending direction of the crown allows for the detection of crown pressing, rotation, and shaking. The arrangement of the magnetic poles offers high flexibility and can be adapted to various application scenarios.

[0012] In one possible implementation, the crown assembly includes a damping element located between the first frame and the crown lever. The damping element may be made of plastic. The damping element is used to increase the tactile feedback of the crown's movement.

[0013] In one possible implementation, the first frame has a through hole communicating with the first cavity. The crown assembly includes a ball bearing surrounding and fixedly connected to the crown rod. The ball bearing is located within the through hole, and the crown can be rocked around the ball bearing. This embodiment of the application, by allowing the crown to rock, increases the crown's freedom of movement, providing possibilities for realizing more functions in wearable devices.

[0014] In one possible implementation, the crown assembly includes a retaining member fixed to the through-hole, with the ball located within the retaining member. The retaining member defines the space for crown movement.

[0015] In one possible implementation, the waterproof component is made of plastic. By making the waterproof component of plastic, the influence of the waterproof component on the magnetic field of the magnetic component is avoided, thereby improving the accuracy of the magnetic detection component in detecting the movement of the crown.

[0016] Secondly, this application provides a watch body, including a motherboard, a magnetic detector, a processor, an analog-to-digital converter, and a crown assembly as described in any of the foregoing embodiments. The magnetic detector, the processor, and the analog-to-digital converter are all electrically connected to the motherboard. The analog-to-digital converter is used to acquire the output signal of the magnetic detector, and the processor is used to process the digital signal converted by the analog-to-digital converter.

[0017] In one possible implementation, the magnetic sensor is a chip, which is used to detect movement of the crown along the extension direction of the crown, and / or, the magnetic sensor is used to detect rotation of the crown in the circumferential direction, and / or, the magnetic sensor is used to detect shaking of the crown.

[0018] In one possible implementation, the magnetic detection element is provided with a trigger threshold and a release threshold. The trigger threshold is used to indicate that the crown moves to a preset pressing position, and the release threshold is used to indicate that the crown moves from the preset pressing position to the initial position. The trigger threshold and the release threshold are different.

[0019] Thirdly, this application provides a wearable device, including a watch strap and a watch body as described in any of the foregoing embodiments, wherein the watch strap is connected to the watch body.

[0020] On the other hand, this application provides a crown assembly. The crown assembly is applied to a watch body, which is used in a wearable device. The crown assembly includes an outer frame, a crown, and a ball bearing. The outer frame has a through hole, and the crown includes a crown cap and a crown rod. The crown cap is located outside the outer frame, and one end of the crown rod is fixedly connected to the crown cap and extends into the through hole. The ball bearing surrounds the crown rod and is fixedly connected to it, and is located in the through hole. The crown can be rocked around the ball bearing. This application improves the crown's freedom of movement by allowing it to rock, providing possibilities for more functions in wearable devices. Understandably, a crown assembly including an outer frame, a crown, and a ball bearing can be applied to a watch body and a wearable device.

[0021] In one possible implementation, the crown assembly includes a retaining member fixed to the inner wall of the through-hole, with the ball located within the retaining member. The retaining member defines the space for crown movement. Attached Figure Description

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] It should be understood that the terms "first," "second," etc., used in this application are for distinguishing purposes only and should not be construed as indicating or implying relative importance or order.

[0053] In the description of this application, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, a mating connection, or an integral connection; those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0055] like Figure 1 and Figure 2 As shown, Figure 1 This is a structural diagram of a wearable device 100. Figure 2 for Figure 1 The diagram shows a partial structural schematic of the crown assembly 50. The wearable device 100 can be a smartwatch. In addition to telling time, the wearable device 100 typically has one or more functions such as reminders, navigation, calibration, monitoring, and interaction. For example, the wearable device 100 can make calls, send and receive text messages, monitor sleep, monitor heart rate, provide sedentary reminders, track steps, take photos remotely, play music, record video, and act as a compass. The multifunctional design and stylish appearance of the wearable device 100 meet user needs and have broad application prospects.

[0056] Wearable device 100 may include a watch strap 101 and a watch body 30. The watch strap 101 may be a single, integrated strap with both ends connected to the watch body 30. Alternatively, the watch strap 101 may be a separate strap, for example, comprising a first strap 10 and a second strap 20. The first strap 10 is connected to one end of the watch body 30, and the second strap 20 is connected to the other end of the watch body 30. Exemplarily, the first strap 10 may be rotatably connected to one end of the watch body 30, and the second strap 20 may be rotatably connected to the other end of the watch body 30. The strap and watch body 30 may be fixedly connected or detachably connected. The strap may be made of metal, leather, nylon, or ribbon, etc.

[0057] The first watch strap 10 and the second watch strap 20 can be connected by a connecting structure ( Figure 1(Not shown) Connection. The connection structure may include a pin buckle. The pin buckle may include a pin connected to the first strap 10 and a plurality of eyelets spaced apart along the length of the second strap 20. The pin can be fixed to the eyelets, connecting the first strap 10 and the second strap 20. It is understood that the tightness of the strap can also be adjusted by adjusting the pin's fixation to the eyelets at different positions.

[0058] The connecting structure may include a butterfly clasp. The two ends of the butterfly clasp can be connected to the first strap 10 and the second strap 20, respectively. When the butterfly clasp is folded and fastened, the first strap 10 and the second strap 20 are relatively close together to fit snugly against the user's wrist or other wearing area, securing the watch around the wrist; when the butterfly clasp is unfolded, the first strap 10 and the second strap 20 are relatively far apart, making it easier to remove the watch from the wrist.

[0059] The connection structure may include a magnetic clasp. For example, the magnetic clasp may include two magnetic tabs respectively disposed on the first watch strap 10 and the second watch strap 20, the two magnetic tabs attracting each other to connect the first watch strap 10 and the second watch strap 20. It is understood that by adjusting the position of the magnetic tabs, the tightness of the watch strap can also be adjusted.

[0060] The connection structure may include Velcro. For example, Velcro may be respectively disposed on the first watch strap 10 and the second watch strap 20, and the two Velcro straps are glued together to connect the first watch strap 10 and the second watch strap 20. It is understood that the tightness of the watch strap can be adjusted by adjusting the position of the Velcro straps.

[0061] After the wearable device 100 is placed on the wrist or other part of the body, the first strap 10 and the second strap 20 can be fastened together, enabling the wearable device 100 to be worn. When the wearable device 100 is no longer needed, the first strap 10 and the second strap 20 can be unfastened to remove the wearable device 100 from its wearing position.

[0062] The watch body 30 may include a motherboard 40 and a crown assembly 50. The motherboard 40 may be a circuit board, housing key components such as a central processing unit, memory, and radio chip, as well as various components connecting the wearable device 100, ensuring the normal operation of the wearable device 100 and its communication with other devices. The motherboard 40 is not limited to... Figure 2 The square shape shown can be replaced by a circular or other shape, and the shape of the motherboard 40 can be designed according to the internal space of the wearable device 100.

[0063] See Figure 1 and Figure 2The crown assembly 50 may include an outer frame 51, which surrounds the edge of the mainplate 40. The outer frame 51 may be round or square, etc. The outer frame 51 may be made of metal, such as aluminum alloy or titanium alloy. Aluminum alloy, as a lightweight and high-strength metal material, not only has excellent wear resistance and corrosion resistance, but also effectively reduces the overall weight of the watch, improving wearing comfort. Titanium alloy is lightweight and high-strength, while also having good corrosion resistance, maintaining stable performance in various environments. The outer frame 51 may also be made of other materials.

[0064] The outer frame 51 may include a first frame 511 and a second frame 512 fixedly connected, with the first frame 511 and the second frame 512 forming a mounting cavity 513. The first frame 511 and the second frame 512 can be an integrally formed structure, resulting in high structural strength, simple manufacturing process, and high manufacturing efficiency for the outer frame 51. Alternatively, the first frame 511 and the second frame 512 can be separate structures assembled and fixed to form the outer frame 51.

[0065] The crown assembly 50 may include a crown 53. The crown 53 serves as a physical button on the wearable device 100, providing a crucial human-computer interaction interface. On a smartwatch, it can integrate operations such as pressing and rotating. Depending on the application scenario, pressing can enable selection and return functions, while rotating can enable menu sliding, volume adjustment, zooming in or out, and other functions.

[0066] The outer frame 51 may have a through hole 5111, into which the crown 53 extends. The crown of the wearable device 100 may be a power button, an operation button, a function button, or other buttons. The crown 53 may be located at the 2 o'clock position, the 3 o'clock position, or the 10 o'clock position of the wearable device 100, etc., and this embodiment does not limit this.

[0067] This application embodiment Figure 1 Taking one crown 53 as an example. In other embodiments, the wearable device 100 may also have two crowns, three crowns, or four crowns, etc. The number of crowns is not limited in this application embodiment.

[0068] The watch body 30 may also include a display screen 60, a front cover 501, and a back cover. Figure 1(Not shown). For example, the front cover 501 may be arranged in a ring around the display screen 60, and the front cover 501 at least partially covers the light-emitting surface of the display screen 60. One end of the outer frame 51 is fixedly connected to the front cover 501, and the other end of the outer frame 51 is fixedly connected to the rear cover. Along the thickness direction of the watch body 30, the display screen 60 and the rear cover are spaced apart on opposite sides of the outer frame 51, that is, the rear cover and the display screen 60 are opposite each other. When the wearable device 100 is worn, the outer surface of the rear cover can contact the user's wrist. In some embodiments, the front cover 501, the outer frame 51, and the rear cover may be integrally formed.

[0069] The front cover 501, the display screen 60 and the back cover can be together with the outer frame 51 to form a mounting cavity 513, which is used to accommodate the main board 40, battery and other components of the watch body 30.

[0070] The display screen 60 has a display function and can display pictures or images to meet user needs. The display screen 60 can be a liquid crystal display, an active matrix organic light-emitting diode display, a miniature light-emitting diode, a miniature organic light-emitting diode display, a quantum dot light-emitting diode display, or an organic light-emitting diode display, etc.

[0071] The battery is located within the mounting cavity 513 of the watch body 30 and can be fixed to the interior of the watch body 30 by a bracket. The battery is used to power the components inside the wearable device 100. The battery is generally large in size, occupying a significant amount of internal space in the wearable device 100. The battery can be square, round, or irregularly shaped, etc., and the shape and position of the battery are not specifically limited in this embodiment.

[0072] The device 30 may also include a processor 31 and an analog-to-digital converter 32, both of which are electrically connected to the motherboard 40. The analog-to-digital converter 32 is used to collect data from the magnetic detection element. Figure 1 Not shown, see reference Figure 2 The processor 31 processes the digital signal converted by the analog-to-digital converter 32 and calculates related operation actions. Figure 1 The position, shape, size, etc. of the processor 31 and the analog-to-digital converter 32 are only schematic representations and can be set as needed. This application embodiment does not limit them.

[0073] Figure 1 The wearable device 100 in this application is only schematic and its size, shape, and specific structure can be customized as needed. This application does not limit the specific structure of the wearable device 100.

[0074] See Figure 1 and Figure 2The crown assembly 50 includes an outer frame 51, a waterproof component 52, a crown 53, and a magnetic component 54. The waterproof component 52 is located in the mounting cavity 513 and fixed to the inner wall 514 of the outer frame 51. Understandably, the inner wall of the first frame 511 and the inner wall of the second frame 512 are integrally connected to form the inner wall 514 of the outer frame 51. The waterproof component 52 and the first frame 511 enclose a first cavity 5131, which is part of the mounting cavity 513. The waterproof component 52 and the second frame 512 enclose a second cavity 5132, which is another part of the mounting cavity 513. In other words, the mounting cavity 513 includes the first cavity 5131 and the second cavity 5132, and the waterproof component 52 isolates the mounting cavity 513 into the first cavity 5131 and the second cavity 5132, which are not interconnected. Isolating the mounting cavity 513 into a first cavity 5131 and a second cavity 5132 by using the waterproof component 52 facilitates the installation of the required structural components in the first cavity 5131 and the second cavity 5132 as needed.

[0075] See Figure 1 and Figure 2 The waterproof component 52 is used to prevent water from entering the second cavity 5132 from the first cavity 5131. The waterproof component 52 can abut against structural members of the watch body 30 to form a closed second cavity 5132. Exemplarily, the open end of the waterproof component 52 is fixedly connected to the inner wall 514 of the outer frame 51, the front side of the waterproof component 52 can abut against the front cover 501 of the watch body 30, and the rear side of the waterproof component 52 can abut against the back cover of the watch body 30, so that the waterproof component 52 can prevent water from entering the second cavity 5132 from the first cavity 5131, making the second cavity 5132 a closed cavity. The waterproof component 52 can also abut against other structures of the watch body to form a closed second cavity 5132. Understandably, the waterproof component 52's prevention of water from entering the second cavity 5132 from the first cavity 5131 helps protect the structure within the second cavity 5132.

[0076] The waterproof component 52 and the outer frame 51 can be integrally molded, or the waterproof component 52 and the front cover 501 of the watch body 30 can be integrally molded, or the waterproof component 52 and the back cover of the watch body 30 can be integrally molded. This provides high structural strength, good sealing performance, and a simple manufacturing process. In other embodiments, the waterproof component 52 and the outer frame 51 can be separate structures assembled and fixed as one unit, or the waterproof component 52 and the front cover 501 of the watch body 30 can be separate structures assembled and fixed as one unit, or the waterproof component 52 and the back cover of the watch body 30 can be separate structures assembled and fixed as one unit.

[0077] Understandably, some structural components that do not require waterproofing or that do not require electrical connection to the motherboard 40 can be housed within the first cavity 5131.

[0078] The crown 53 may include a crown cap 531 and a crown lever 532 that are fixedly connected. The crown cap 531 and crown lever 532 can be a single molded structure, resulting in high structural strength, simple manufacturing process, and high manufacturing efficiency for the crown 53. Alternatively, the crown cap 531 and crown lever 532 can be separate structures assembled to form the crown 53. Textures may be provided on the crown cap 531 to facilitate finger twisting and adjustment of the smartwatch.

[0079] The through hole 5111 of the outer frame 51 can be located in the first frame 511, and the through hole 5111 communicates with the first cavity 5131. The crown cap 531 is located outside the outer frame 51, the first end 5321 of the crown rod 532 is fixedly connected to the crown cap 531, and the second end 5322 of the crown rod 532 extends into the first cavity 5131.

[0080] The crown assembly 50 may include a limiting structure 56, which is located in the first cavity 5131 and connected to the second end 5322 of the crown lever 532. The limiting structure 56 prevents the crown 53 from moving out of the first cavity 5131 along a first direction A1 and disengaging from the outer frame 51. The first direction A1 is the extension direction of the crown 53. The limiting structure 56 may be a nut or similar structure.

[0081] The magnetic element 54 can be fixed to the crown 53 at the second end 5322 of the crown lever 532. Understandably, the magnetic element 54 is located in the first cavity 5131. The shape of the magnetic element 54 can be circular, square, or other shapes; this embodiment does not limit this.

[0082] The watch body 30 may include a magnetic detection element 55. The magnetic detection element 55 is mounted to the second cavity 5132, and detects the movement of the crown 53 by detecting changes in the magnetic field of the magnetic element 54 at the location of the magnetic detection element 55. Understandably, changes in the magnetic field of the magnetic element 54 will affect the signal output of the magnetic detection element 55, and the movement of the crown 53 can be detected based on the output signal of the magnetic detection element 55.

[0083] On the wearable device 100, functions can be adjusted by operating the crown 53. During the movement of the crown 53, the magnetic component 54 moves. The magnetic detection component 55 detects the movement of the crown 53 by detecting changes in the magnetic field of the magnetic component 54, and then performs the corresponding operation. The magnetic detection component 55 can be a chip, etc. The magnetic detection component 55 needs to be waterproof to prevent damage from contact with water.

[0084] In this embodiment, a magnetic component 54 is fixed to the second end 5322 of the crown 53. A magnetic detection component 55 detects the movement of the crown 53 by detecting changes in the magnetic field of the magnetic component 54 at the location of the magnetic detection component 55. This magnetic detection design allows the magnetic detection component 55 and the magnetic component 54 to be in different spaces while still achieving detection. By placing the magnetic component 54 in the first cavity 5131 and the magnetic detection component 55 in the second cavity 5132, a waterproof component 52 isolates the magnetic component 54 and the magnetic detection component 55 in different spaces, thus providing waterproof protection for the magnetic detection component 55. By placing the magnetic detection component 55, which requires waterproof protection, in the second cavity 5132, there is no requirement for waterproof performance in the first cavity 5131. Furthermore, no waterproof structure is needed between the crown stem 532 and the through hole 5111 of the first frame 511, resulting in a simpler and less complex waterproof structure. During the movement of the crown 53, the waterproof component 52 remains stationary, meaning that the position of the waterproof component 52 relative to the outer frame 51 is fixed. This ensures that the waterproof component 52 has high reliability and stability, and provides good waterproofing to the magnetic detection component 55 with a high waterproof rating.

[0085] In some embodiments, the waterproof component 52 may be made of plastic to avoid the influence of the magnetic field of the magnetic component 54 on the waterproof component 52, thereby improving the accuracy of the magnetic detection component 55 in detecting the movement of the crown 53. The waterproof component 52 may also be made of other materials, which are not limited in this embodiment.

[0086] In some embodiments, the crown assembly 50 is provided with a flexible circuit board ( Figure 2 (Not shown), the flexible circuit board is fixed to the second surface 522, the magnetic detection element 55 is fixed and electrically connected to the flexible circuit board, and the flexible circuit board is electrically connected to the main board 40 (see...). Figure 1 This enables the magnetic detection component 55 to be electrically connected to the motherboard 40.

[0087] See Figure 1 and Figure 2 In some embodiments, since the magnetic detection element 55 is located in the second cavity 5132, the second cavity 5132 needs to be waterproofed by the waterproof element 52, while the first cavity 5131 may not require waterproofing. Because the magnetic element 54 is located in the open first cavity 5131, which is connected to the outside world through a through-hole 5111, it can come into contact with air, water, and other external substances. To protect the magnetic element 54, a plating layer (the plating material can be nickel) can be applied to its surface, followed by an epoxy resin spray coating to prevent oxidation and other factors that could affect its magnetic field performance.

[0088] See Figure 2The magnetic detector 55, magnetic component 54, and crown 53 can be arranged sequentially along the first direction A1. The central axes of the magnetic detector 55, magnetic component 54, and crown 53 can be collinear and parallel to the first direction A1. This embodiment of the application, by setting the central axes of the magnetic detector 55, magnetic component 54, and crown 53 to be collinear, makes the detection of the crown 53 more accurate and simpler, avoiding the need for the wearable device system to correct the collected data when the central axes of the magnetic detector 55, magnetic component 54, and crown 53 are not collinear. It is understood that in other embodiments, the central axes of the magnetic detector 55, magnetic component 54, and crown 53 may not be collinear, depending on the specific requirements.

[0089] For example, the waterproof component 52 may include a first side portion 524, a second side portion 525, and a third side portion 526. The magnetic detection component 55 may be located on the second side portion 525 such that the central axis of the magnetic detection component 55, the central axis of the magnetic component 54, and the central axis of the crown 53 are collinear and parallel to the first direction A1. In other embodiments, the magnetic detection component 55 may be located on the first side portion 524 or the third side portion 526. Figure 2 The structure, shape, and size of the waterproof component 52 are only schematic representations and can be set as needed.

[0090] In some embodiments, the waterproof component 52 may include a first surface 521 and a second surface 522. The first surface 521 faces the first cavity 5131, and the second surface 522 faces the second cavity 5132, with the first surface 521 and the second surface 522 positioned opposite to each other. The magnetic detection component 55 may be fixed to the second surface 522 of the waterproof component 52, making the distance between the magnetic detection component 55 and the magnetic component 54 relatively close. This allows for accurate acquisition of the magnetic field changes of the magnetic component 54 at the location of the magnetic detection component 55, improving detection accuracy. In other embodiments, the magnetic detection component 55 and the waterproof component 52 may be spaced apart, meaning the magnetic detection component 55 may not be located on the second surface 522 of the waterproof component 52. This application does not limit this aspect.

[0091] See Figure 2 and Figure 3 , Figure 3 for Figure 2The diagram shows the structure of the magnetic component 54. The magnetic component 54 may include a first magnetic pole 541 and a second magnetic pole 542, which can be arranged along a first direction A1. The first magnetic pole 541 can be an N pole, and the second magnetic pole 542 can be an S pole, or vice versa. When the magnetic detection component 55 detects the movement of the crown 53 along the first direction A1, the crown 53 drives the magnetic component 54 to move along the first direction A1. By arranging the first magnetic pole 541 and the second magnetic pole 542 along the first direction A1, the magnetic detection component 55 can detect changes in the magnetic field of the magnetic component 54 at the location of the magnetic detection component 55.

[0092] See Figure 2 The crown assembly 50 may include a damping element 57, which is located between the first frame 511 and the crown lever 532. The damping element 57 is fitted onto the outside of the crown lever 532 and located in the through hole 5111 of the first frame 511. The damping element 57 may be made of plastic. The damping element 57 is used to increase the tactile feel of adjusting the movement of the crown 53.

[0093] like Figure 4 As shown, Figure 4 for Figure 1 This is a partial structural schematic diagram of another crown assembly 50. The second surface 522 of the waterproof component 52 has a groove 523, and the magnetic detection component 55 is located within the groove 523. Exemplarily, the surface 551 of the magnetic detection component 55 may be flush with the surface of the waterproof component 52, or the surface 551 of the magnetic detection component 55 may be located within the groove 523, or the surface 551 of the magnetic detection component 55 may be located outside the groove 523, i.e., the magnetic detection component 55 protrudes from the groove 523. A flexible circuit board may be fixed to the bottom wall of the groove 523, the magnetic detection component 55 is fixed and electrically connected to the flexible circuit board, and the flexible circuit board is electrically connected to the main board.

[0094] By positioning the magnetic detector 55 within the groove 523, the space occupied by the magnetic detector 55 and the waterproof component 52 in the mounting cavity 513 of the crown assembly 50 can be reduced, which is beneficial for the miniaturization of the wearable device 100, and the waterproof component 52 can protect the magnetic detector 55.

[0095] Figure 2 and Figure 4 The magnetic detection element 55 of the crown assembly 50 can detect the movement of the crown 53 along the first direction A1. Figure 2 For example, the crown component 50 in the watch, see Figure 5 , Figure 6 and Figure 7 , Figure 5 for Figure 2 The diagram shows the crown 53 of the crown assembly 50 in the pressed state. Figure 6 for Figure 2 The diagram shows the crown 53 of the crown assembly 50 in the released state. Figure 7 for Figure 2 The changes in the magnetic field detected by the magnetic sensor 55 and the output signal of the crown 53 of the crown assembly 50 shown during pressing and releasing.

[0096] The magnetic detection element 55 can be a magnetic switch chip. Figure 5 The middle indicates that the crown 53 can be pressed to the left along the first direction A1. Figure 5 The arrow in the image indicates the direction in which crown 53 is pressed. Figure 6 The text indicates that crown 53 can be released to the right along the first direction A1, i.e., crown 53 can be loosened. Figure 6 The arrow in the diagram indicates the direction in which the crown 53 is released. The crown 53 can be repeatedly pressed and released along the first direction A1 to perform corresponding operations, such as selection or return.

[0097] Figure 7 The diagram shows the relationship between the magnetic field strength at the location of the magnetic detection element and the chip output. (See Crown 53) Figure 5 During the pressing process, the magnetic field strength gradually increases as the pressing stroke progresses, reaching the magnetic detection element 55 (see...). Figure 5 After the threshold is reached, the chip output changes from 0 to 1, and the microprocessor ( Figure 7 (Not shown) A press action was detected. Crown 53 (see...) Figure 6 During the release process, as the magnetic field strength gradually decreases during the release journey, it reaches the magnetic detection element 55 (see...). Figure 6 After the threshold is reached, the chip output changes from 1 to 0, returning to its initial state. The wearable device performs corresponding operations based on the output of the magnetic detector.

[0098] Understandably, when the magnetic detector 55 is located at the first side 524 or the third side 526, the waveform of the output signal of the magnetic detector 55 is similar to... Figure 7 They can be basically the same.

[0099] In some embodiments, the magnetic sensor 55 has a trigger threshold and a release threshold. The trigger threshold indicates that the crown 53 moves to a preset pressing position, triggering a pressing action. The release threshold indicates that the crown 53 moves from the preset pressing position back to the initial position, ending the pressing action. The initial position refers to the position of the crown 53 when there is no pressing action. The trigger threshold and the release threshold are different. To reduce the jitter caused by the magnetic field strength sensed by the magnetic sensor 55 fluctuating around the trigger threshold / release threshold, resulting in a large number of false touches, the magnetic sensor 55 is typically designed with a difference between the trigger threshold and the release threshold, rather than the same magnetic field strength, to reduce the resulting jitter.

[0100] like Figure 8 and Figure 9 As shown, Figure 8 for Figure 1 A partial structural schematic diagram of another crown component 50 is shown. Figure 9 for Figure 8 The diagram shows the structure of the magnetic component 54. Figure 8 and Figure 9 The crown assembly 50 shown is... Figures 2-7 The differences in the crown assembly 50 shown include, but are not limited to, the different arrangement directions of the magnetic poles of the magnetic element 54, the different types of the magnetic detection element 55, and the fact that the crown 53 can be pressed and rotated.

[0101] The first magnetic pole 541 and the second magnetic pole 542 of the magnetic component 54 can be arranged along the second direction A2. The second direction A2 is perpendicular to the first direction A1. The first magnetic pole 541 can be the N pole and the second magnetic pole 542 can be the S pole, or the first magnetic pole 541 can be the S pole and the second magnetic pole 542 can be the N pole.

[0102] The magnetic detection element 55 can be a magnetic angle sensing chip. The magnetic angle sensing chip can detect the pressing and rotation of the crown 53. When the magnetic detection element 55 detects the pressing movement of the crown 53 along the first direction A1, the crown 53 drives the magnetic element 54 to move along the first direction A1. By arranging the first magnetic pole 541 and the second magnetic pole 542 along the second direction A2, the magnetic detection element 55 can detect the change in the magnetic field of the magnetic element 54 at its location. When the magnetic detection element 55 detects the rotation of the crown 53 in the circumferential direction, the crown 53 drives the magnetic element 54 to rotate in the circumferential direction. By arranging the first magnetic pole 541 and the second magnetic pole 542 along the second direction A2, the magnetic detection element 55 can detect the change in the magnetic field of the magnetic element 54 at its location, thereby determining the rotation angle and rotation speed of the crown 53.

[0103] like Figure 10 , Figure 11 and Figure 12 , Figure 10 for Figure 8 The diagram shows the crown 53 of the crown assembly 50 in the pressed state. Figure 11 for Figure 8 The diagram shows the crown 53 of the crown assembly 50 in the released state. Figure 12 for Figure 8 The changes in the magnetic field detected by the magnetic sensor 55 and the output signal of the crown 53 of the crown assembly 50 shown during pressing and releasing.

[0104] Figure 10 The middle indicates that the crown 53 can be pressed to the left along the first direction A1. Figure 10 The arrow in the image indicates the direction in which crown 53 is pressed. Figure 11The text indicates that crown 53 can be released to the right along the first direction A1, i.e., crown 53 can be loosened. Figure 11 The arrow in the diagram indicates the direction in which the crown 53 is released. The crown 53 can be repeatedly pressed and released along the first direction A1 to perform corresponding operations, such as selection or return.

[0105] Figure 12 The diagram illustrates the relationship between the magnetic field strength at the location of the magnetic detection element 55 and the chip output. When the crown is pressed along the first direction, the magnetic element at the end of the crown moves along the first direction. The magnetic detection element acquires two signals, Vx and Vy, which are orthogonal to each other, and their values ​​increase with the pressing of the crown. The change in magnetic field strength in the first direction can be obtained by calculating the vector sum of the Vx and Vy signals. The change in magnetic field strength in the first direction is positively correlated with the gap distance between the magnetic element and the magnetic angle sensing chip. By setting a corresponding trigger threshold, the pressing action of the crown can be detected. X The signal is an X-axis signal, V Y This is the Y-axis signal. Both the X-axis and Y-axis are perpendicular to the first direction.

[0106] like Figure 13 As shown, Figure 13 for Figure 8 The diagram shows the crown 53 of the crown assembly 50 in a rotating state. Figure 13 The crown 53 can rotate along the circumferential direction A3, causing the magnetic element 54 at the end of the crown 53 to rotate along the circumferential direction A3. The rotation angle range of the crown 53 can be greater than 0° and less than or equal to 360°. The specific rotation angle can be operated as needed, and this embodiment does not limit it.

[0107] Understandably, taking a circular end face 5311 of the crown cap 531 away from the crown lever 532 as an example, the plane containing the circumferential direction A3 can be parallel to the circular end face 5311. The circumferential direction A3 is also the direction of the circumference of the circular end face 5311. In other embodiments, the end face 5311 of the crown cap 531 away from the crown lever 532 can also be square or other shapes.

[0108] like Figure 14 As shown, Figure 14 for Figure 13 The crown 53 of the crown assembly 50 shown outputs a signal from the magnetic sensor 55 during rotation. When the crown rotates circumferentially, it causes the magnetic component at the end of the crown to rotate circumferentially as well. The magnetic angle sensing chip acquires two signals, which are orthogonal V... X Signal and V Y Signal, V X Signal and V YThe signal value changes as the magnetic component rotates. According to the formula: The collected output V X Signal and V Y The signals are substituted into the AV in the formula. X and BV Y After calculation, the actual angle θ of the magnetic component can be obtained. By calculating the difference in angle change, the rotation of the crown can be detected. A and B both represent the output amplitude coefficients, V X The signal is an X-axis signal, V Y This is the Y-axis signal. Both the X-axis and Y-axis are perpendicular to the first direction.

[0109] like Figure 15 , Figure 16 and Figure 17 As shown, Figure 15 for Figure 1 A partial structural schematic diagram of another crown component 50 is shown. Figure 16 for Figure 15 A three-dimensional structural diagram of another partial structure of the crown assembly 50 is shown. Figure 16 Structure and Figure 15 Their structures are not entirely the same. Figure 16 Taking the outer frame 51 as an example. Figure 17 for Figure 16 An enlarged view of a partial three-dimensional structure of another crown component 50 is shown. Figure 15 , Figure 16 and Figure 17 The crown assembly 50 shown is... Figures 2-7 The differences in the crown assembly 50 shown include, but are not limited to, the different arrangement directions of the magnetic poles of the magnetic element 54, the different types of magnetic detection elements 55, and the fact that the crown 53 can be pressed, rotated, and shaken.

[0110] The first magnetic pole 541 and the second magnetic pole 542 of the magnetic component 54 can be arranged along the second direction A2. The second direction A2 is perpendicular to the first direction A1. The first magnetic pole 541 can be the N pole and the second magnetic pole 542 can be the S pole, or the first magnetic pole 541 can be the S pole and the second magnetic pole 542 can be the N pole.

[0111] The crown assembly 50 may include a ball 58 and a limiting member 59. The limiting member 59 is fixed to the inner wall of the through hole 5111. The ball 58 surrounds and is fixedly connected to the crown lever 532, and is located within the limiting member 59; in other words, the ball 58 is located within the through hole 5111. The limiting member 59 defines the space for the crown 53 to rock. The crown 53 can rock about the ball 58.

[0112] The magnetic detection element 55 can be a three-dimensional magnetic induction chip. The three-dimensional magnetic induction chip can detect the pressing, rotation, and shaking of the crown 53. When the magnetic detection element 55 detects the pressing movement of the crown 53 along the first direction A1, the crown 53 drives the magnetic element 54 to move along the first direction A1. By arranging the first magnetic pole 541 and the second magnetic pole 542 along the second direction A2, the magnetic detection element 55 can detect the change in the magnetic field of the magnetic element 54 at its location. When the magnetic detection element 55 detects the rotation of the crown 53 in the circumferential direction, the crown 53 drives the magnetic element 54 to rotate in the circumferential direction. By arranging the first magnetic pole 541 and the second magnetic pole 542 along the second direction A2, the magnetic detection element 55 can detect the change in the magnetic field of the magnetic element 54 at its location, thereby determining the rotation angle and rotation speed of the crown 53. When the crown 53 is shaken, the magnetic detector 55 detects the movement of the magnetic component 54. By setting the first magnetic pole 541 and the second magnetic pole 542 to be arranged along the second direction A2, the magnetic detector 55 can detect the change in the magnetic field of the magnetic component 54 at the location of the magnetic detector 55, so as to determine the shaking direction, angle, speed, etc. of the crown 53.

[0113] like Figure 18 , Figure 19 and Figure 20 , Figure 18 for Figure 15 The diagram shows the crown 53 of the crown assembly 50 in the pressed state. Figure 19 for Figure 15 The diagram shows the crown 53 of the crown assembly 50 in the released state. Figure 20 for Figure 15 The changes in the magnetic field detected by the magnetic sensor 55 and the output signal of the crown 53 of the crown assembly 50 shown during pressing and releasing.

[0114] Figure 18 The middle indicates that the crown 53 can be pressed to the left along the first direction A1. Figure 18 The arrow in the image indicates the direction in which crown 53 is pressed. Figure 19 The text indicates that crown 53 can be released to the right along the first direction A1, i.e., crown 53 can be loosened. Figure 19 The arrow in the diagram indicates the direction in which the crown 53 is released. The crown 53 can be repeatedly pressed and released along the first direction A1 to perform corresponding operations, such as selection or return.

[0115] Figure 20The diagram illustrates the relationship between the magnetic field strength at the location of the magnetic detection element 55 and the chip output. When the crown is pressed along the first direction, the magnetic element at the end of the crown moves along the first direction. The three-dimensional magnetic induction chip acquires three signals: an X-axis signal, a Y-axis signal, and a Z-axis signal. These signals are orthogonal to each other, and their values ​​change with the pressing of the magnetic element. For the press detection, the change in magnetic field strength in the XY plane can be obtained by calculating the vector sum of the X-axis and Y-axis signals. The change in magnetic field strength in the XY plane is positively correlated with the distance between the magnetic element and the three-dimensional magnetic induction chip. By setting a corresponding trigger threshold, the pressing action of the crown can be detected. It can be understood that the Z-axis is parallel to the first direction, and the X-axis and Y-axis are both perpendicular to the Z-axis.

[0116] like Figure 21 As shown, Figure 21 for Figure 15 The diagram shows the crown 53 of the crown assembly 50 in a rotating state. Figure 21 The crown 53 can rotate along the circumferential direction A3, causing the magnetic element 54 at the end of the crown 53 to rotate along the circumferential direction A3. The rotation angle range of the crown 53 can be greater than 0° and less than or equal to 360°. The specific rotation angle can be operated as needed, and this embodiment does not limit it.

[0117] like Figure 22 As shown, Figure 22 for Figure 21 The crown 53 of the crown assembly 50 shown outputs the magnetic sensor 55 during rotation. When the crown rotates circumferentially, it drives the magnetic component at the end of the crown to rotate circumferentially as well. The three-dimensional magnetic induction chip acquires three signals: an X-axis signal, a Y-axis signal, and a Z-axis signal, which are orthogonal to each other. The magnitudes of the X-axis and Y-axis signals change with the rotation of the magnetic component. According to the formula: Substitute the amplitude values ​​of the acquired X-axis and Y-axis signals into the AV value in the formula. X and BV Y By calculation, the actual angle θ of the magnetic component can be obtained. By calculating the difference in angle change, the rotation of the crown can be detected.

[0118] like Figure 23 , Figure 24 and Figure 25 , Figure 23 for Figure 15 The diagram shows a crown 53 of the crown assembly 50 that is rocked in one direction. Figure 24 for Figure 15 A schematic diagram of the structure of the crown 53 of the crown assembly 50 shown, which is rocked in another direction.

[0119] Figure 23 The middle indicates that crown 53 can be rocked upwards, that is, crown 53 can be raised. Figure 24 The text indicates that crown 53 can be rocked downwards, i.e., pressed down, to perform the corresponding operation. Understandably, Figure 23 The direction of the crown 53's shaking is the same as Figure 24 The crown can be rocked in the opposite direction or not, and the crown 53 can also be rocked in other directions. This application embodiment does not limit the rocking direction of the crown 53. By setting the crown 53 to be rockable, this application embodiment increases the degree of freedom of movement of the crown 53, providing possibilities for the realization of more functions of wearable devices.

[0120] Figure 25 for Figure 15 The output of the magnetic detection element 55 during the shaking process of the crown 53 of the crown assembly 50 shown. The crown can be shaken in the XY plane. When the crown is shaken in various directions such as lifting, pressing down, moving left, and moving right, the crown will drive the magnetic element at the end of the crown to move accordingly. The three-dimensional magnetic induction chip will acquire three signal information along the X, Y, and Z axes, where the signal magnitudes of the X, Y, and Z axes change to different degrees with the movement of the magnetic element. By calculating the three-dimensional signals, the actual translational movement of the magnetic element can be obtained, thereby obtaining the action detection capability of the crown in various directions such as lifting, pressing down, moving left, and moving right.

[0121] Understandably, after the magnetic detector 55 outputs one-dimensional, two-dimensional, or three-dimensional analog signals, the analog-to-digital converter acquires the data, converts the analog quantity into a digital signal, processes it through an algorithm, and generates the result of pressing, rotating, or shaking. The wearable device then processes and responds to the reported information.

[0122] Understandably, in some embodiments, when the magnetic element 54 and the magnetic detection element 55 are not provided, or when the magnetic detection element 55 is not located in the second cavity 5132, the crown 53 can be set to rock around the ball 58.

[0123] like Figure 26 As shown, Figure 26 This is a schematic diagram illustrating an application scenario of the wearable device 100. The wearable device 100 in this embodiment of the application can have underwater touch interaction functionality.

[0124] Wearable device 100 can use a capacitive screen. Capacitive screen technology works by utilizing the electrical current sensing of the human body. When a finger touches the metal layer, due to the human body's electric field, a coupling capacitor is formed between the user and the touchscreen surface. For high-frequency currents, the capacitor is a direct conductor, so the finger draws a small current from the contact point. This current flows out from the electrodes at the four corners of the touchscreen, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. The controller determines the position of the touch point by accurately calculating the ratio of these four currents. Capacitive screens have advantages such as fast response speed, multi-touch support, clear display, easy cleaning, smooth operation, high durability, low light loss and system power consumption, and less prone to accidental touches.

[0125] Currently, capacitive screens are typically unusable underwater due to the water's influence. The three crown components of this application, offering pressing, pressing and rotating, and pressing, rotating, and shaking designs respectively, enable capacitive screens to perform human-computer interaction functions underwater. Taking a wearable device 100 with a crown component 50 that allows pressing, rotating, and shaking as an example, any watch human-computer interaction function can be completed using only the movement of the crown 53. For instance, pressing activates the shortcut menu, and pressing, rotating, and shaking allow for application processing, quickly activating and selecting applications, editing messages, etc.

[0126] like Figure 27 As shown, Figure 27 This is a schematic diagram illustrating another application scenario of the wearable device 100. The wearable device 100 of this application embodiment can have the function of operating a smart car via a watch. Taking the wearable device 100 with a crown assembly 50 that allows for pressing, rotating, and shaking as an example, any human-computer interaction function of the watch can be completed using only the movement of the crown 53. For instance, by shaking the crown 53, the car 200 can be controlled within the parking lot 300 to perform simple exit control operations, enabling the car 200 to move within the parking lot 300.

[0127] like Figure 28 As shown, Figure 28 This is a schematic diagram illustrating another application scenario of the wearable device 100. The wearable device 100 of this application embodiment can have the function of operating a drone via a watch. Taking a wearable device 100 with a crown component 50 that allows for pressing, rotating, and shaking as an example, any human-computer interaction function of the watch can be completed simply by using the movement of the crown 53. For example, the angle of the gimbal camera on the drone 400 can be controlled by shaking the crown 53, and the flight behavior of the drone 400 can be controlled by the watch face.

[0128] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
