Description

Technical Field

[0001] This invention relates to the field of electronic product technology, and more particularly to a crown and a watch. Background Technology

[0002] With the rapid development of technology, drones have been widely used in many fields such as aerial photography, surveying, and logistics, and their operation and control methods are constantly being innovated. As a convenient wearable device, smartwatches, with their multiple sensors and communication functions, are gradually being explored for controlling drones, with the aim of achieving a more convenient and portable drone control experience.

[0003] However, current solutions for controlling drones using smartwatches still have many problems. In terms of hardware design, while existing joystick-based smartwatches include joystick controls, the protruding structure of the joystick makes accidental touches very easy to occur during daily use, affecting the normal operation of the drone. For smartwatches without joysticks, operation relies mainly on gestures or rotating the crown, which is less precise than a professional remote control. In follow-up shooting scenarios, even subtle changes in the user's gestures can cause the drone to misjudge its direction, and the object being followed can easily deviate from the center of the frame. Furthermore, the user experience is unsatisfactory. Smartwatches have a long delay when controlling drones via gestures, making real-time control impossible. This severely impacts the operational effectiveness in scenarios requiring quick reactions, and users cannot simultaneously pay attention to the drone's surroundings, increasing the risk of collisions and other accidents. A solution that balances everyday wearability and professional operation is needed. Summary of the Invention

[0004] Based on the above, the purpose of this invention is to provide a crown and watch that enable the control of a drone to perform corresponding operations via a joystick, thereby improving the efficiency, accuracy, and comfort of drone operation. The joystick can also be locked and stored inside the crown to prevent accidental triggering, significantly improving the reliability of use and meeting both daily wear and professional operation needs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] On one hand, a crown is provided, including a housing and a rocker assembly; the rocker assembly includes a limiting outer shell, a rocker, and an adjusting component, the housing having a first through hole, the limiting outer shell having a limiting hole, the limiting outer shell being disposed within the housing, the rocker passing through the first through hole and the limiting hole, the rocker having a limiting piece, the adjusting component being connected to the rocker, the adjusting component being configured to adjust the position of the rocker, the position of the rocker including at least a first position and a second position, in the first position, the limiting piece is not embedded in the limiting hole, and the rocker can swing; in the second position, when the limiting piece is embedded in the limiting hole, the rocker cannot swing.

[0007] As a preferred technical solution for the crown, a swing gap is provided between the limiting outer shell and the housing. The rocker arm passes through the first through hole, the swing gap and the limiting hole in sequence. In the first position, the limiting piece moves into the swing gap so that the rocker arm can swing.

[0008] As a preferred embodiment of the crown, the adjustment component includes a drive inner housing and a rocker base; the rocker arm elastically abuts against the rocker base;

[0009] The limiting housing is provided with a plurality of first limiting notches and a plurality of second limiting notches at one end near the rocker base. The first limiting notches and the second limiting notches are alternately arranged circumferentially. The length of the first limiting notch along the axis of the limiting hole is greater than the length of the second limiting notch along the axis of the limiting hole.

[0010] The driving inner shell is slidably connected to the limiting outer shell, and the driving inner shell is driven to the rocker base. The rocker base is provided with a limiting protrusion. When the rocker is pressed, the driving inner shell is used to drive the rocker base to rotate so that the limiting protrusion is aligned with the first limiting notch or the second limiting notch. When the rocker is released, the limiting protrusion is embedded in the aligned first limiting notch or the second limiting notch.

[0011] When the limiting protrusion is embedded in the first limiting notch, the limiting piece is located in the swing gap; when the limiting protrusion is embedded in the first limiting notch, the limiting piece is embedded in the limiting hole.

[0012] As a preferred technical solution for the crown, the adjustment component further includes a first elastic element, a second elastic element, and a third elastic element. The first elastic element is located between the limiting piece and the inner wall of the housing. The second elastic element is located between the end of the driving inner housing away from the rocker base and the limiting outer housing. The third elastic element elastically abuts against the end of the rocker base away from the rocker. The elastic force of the third elastic element is greater than the sum of the elastic forces of the first elastic element and the second elastic element.

[0013] The drive inner housing is provided with a plurality of first guide slopes at circumferential intervals at one end near the rocker base. The limiting protrusion is provided with a second guide slope that cooperates with the first guide slopes. When the limiting protrusion is embedded in the first limiting notch and the second limiting notch, the second guide slope abuts against the middle position of the first guide slope.

[0014] As a preferred technical solution for the crown, a third guide slope that cooperates with the second guide slope is provided at the opening of the first limiting notch and the second limiting notch.

[0015] As a preferred technical solution for the crown, there are four limiting protrusions, four first limiting notches, and four second limiting notches; and eight first guide slopes.

[0016] As a preferred technical solution for the crown, the inner wall of the limiting shell is provided with a plurality of guide grooves spaced apart circumferentially, and the outer wall of the driving inner shell is provided with a plurality of guide protrusions spaced apart circumferentially, the guide protrusions being slidably connected to the guide grooves.

[0017] As a preferred technical solution for the crown, the rocker assembly further includes a waterproof component, which is disposed between the rocker and the rocker base. The waterproof component has a sealing groove, and the end of the rocker near the rocker base is sealed to the opening of the sealing groove. A circuit board is disposed inside the sealing groove.

[0018] As a preferred technical solution for the crown, the bottom of the sealing groove is provided with a first wiring hole, the rocker base is provided with a second wiring hole, the waterproof component is sealed against the end face of the second wiring hole, and the wiring harness of the circuit board passes through the first wiring hole and the second wiring hole.

[0019] On the other hand, a watch is provided, including a watch strap and a crown as described in any of the above embodiments, the watch strap being connected to the crown.

[0020] The beneficial effects of this invention are as follows:

[0021] This invention provides a crown and a watch. When the watch is needed to control a drone, an adjusting component adjusts the position of the joystick. The adjusting component moves the joystick to a first position, where the limiting plate is not engaged in the limiting hole, allowing the joystick to swing. The joystick controls the drone to perform corresponding operations, achieving drone control. Compared to gesture control, this significantly improves the efficiency, precision, and comfort of drone operation, making it particularly suitable for professional aerial photography and complex environment operations. When the watch is not needed to control the drone, the adjusting component moves the joystick to a second position, where the limiting plate is engaged in the limiting hole. In this position, the joystick cannot swing but can only rotate, locked and stored inside the crown, preventing accidental triggering and significantly improving reliability.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0031] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0034] like Figures 1-4 As shown, this embodiment provides a watch, including a watch strap and a crown. The watch strap is connected to the crown, which includes a housing 1 and a rocker assembly 2. The rocker assembly 2 includes a limiting housing 21, a rocker 22, and an adjusting component 23. The housing 1 is provided with a first through hole 11, and the limiting housing 21 is provided with a limiting hole 211. The limiting housing 21 is disposed inside the housing 1. The rocker 22 passes through the first through hole 11 and the limiting hole 211. The rocker 22 is provided with a limiting piece 221. The adjusting component 23 is connected to the rocker 22 and is configured to adjust the position of the rocker 22. The position of the rocker 22 includes at least a first position and a second position. In the first position, the limiting piece 221 is not embedded in the limiting hole 211, and the rocker 22 can swing. In the second position, when the limiting piece 221 is embedded in the limiting hole 211, the rocker 22 cannot swing.

[0035] When the watch is needed to control the drone, the adjusting component 23 adjusts the position of the joystick 22. The adjusting component 23 adjusts the joystick 22 to the first position. At this time, the limiting piece 221 is not embedded in the limiting hole 211, and the joystick 22 can swing. The joystick 22 controls the drone to perform corresponding operations, thus achieving drone control. Compared with gesture control, this significantly improves the efficiency, accuracy, and comfort of drone control, making it especially suitable for professional aerial photography, complex environment operations, and other scenarios. When the watch is not needed to control the drone, the adjusting component 23 adjusts the joystick 22 to the second position, so that the limiting piece 221 of the joystick 22 is embedded in the limiting hole 211. At this time, the joystick 22 cannot swing under the limitation of the inner wall of the limiting hole 211, but can only rotate. The joystick 22 is locked and stored inside the crown, thus avoiding accidental triggering and significantly improving the reliability of use. It can meet both daily wear and professional operation needs.

[0036] Preferably, a swing gap 12 is provided between the limiting outer shell 21 and the housing 1. The rocker arm 22 passes through the first through hole 11, the swing gap 12, and the limiting hole 211 in sequence. In the first position, the limiting piece 221 moves into the swing gap 12, and the swing gap 12 provides swing space for the limiting piece 221 of the rocker arm 22 so that the rocker arm 22 can swing. In the second position, the limiting hole 211 restricts the swing of the limiting piece 221.

[0037] Preferably, the rocker arm 22 is provided with a knob 222 at one end located outside the housing 1, which can be pressed or rotated by the operator to improve the ease of operation.

[0038] Furthermore, the adjusting component 23 includes a driving inner shell 231 and a rocker base 232; the rocker 22 elastically abuts against the rocker base 232; the limiting outer shell 21 near the rocker base 232 is provided with a plurality of first limiting notches 212 and a plurality of second limiting notches 213, the first limiting notches 212 and the second limiting notches 213 are alternately arranged circumferentially, the length of the first limiting notch 212 along the axis of the limiting hole 211 is greater than the length of the second limiting notch 213 along the axis of the limiting hole 211; the driving inner shell 231 is slidably connected inside the limiting outer shell 21, and the driving inner shell 231 is drivenly connected to the rocker. The base 232 and the rocker base 232 are provided with a limiting protrusion 2321. When the rocker 22 is pressed, the inner shell 231 drives the rocker base 232 to rotate so that the limiting protrusion 2321 is aligned with the first limiting notch 212 or the second limiting notch 213. When the rocker 22 is released, the limiting protrusion 2321 is embedded in the aligned first limiting notch 212 or the second limiting notch 213. When the limiting protrusion 2321 is embedded in the first limiting notch 212, the limiting piece 221 is located in the swing gap 12. When the limiting protrusion 2321 is embedded in the first limiting notch 212, the limiting piece 221 is embedded in the limiting hole 211. When it is necessary to switch the state of the joystick 22, press the joystick 22. The joystick base 232 moves away from the limiting shell 21 until the limiting protrusion 2321 disengages from one of the first limiting notch 212 and the second limiting notch 213. The inner shell 231 drives the joystick base 232 to rotate so that the limiting protrusion 2321 aligns with the other of the first limiting notch 212 and the second limiting notch 213. Then release the joystick 22, and the limiting protrusion 2321 is embedded in the aligned first limiting notch 212 or second limiting notch 213. Since the first limiting notch 212 and the second limiting notch 213 have different lengths along the first direction... Furthermore, the rocker arm 22 elastically abuts against the rocker arm base 232, and the rocker arm base 232 can rotate relative to the rocker arm 22 and abut against the rocker arm 22 in real time. When the limiting protrusion 2321 of the rocker arm base 232 is embedded in the first limiting notch 212, the rocker arm base 232 is closer to the limiting hole 211, and the rocker arm base 232 drives the limiting piece 221 of the rocker arm 22 to move to the swing gap 12. When the limiting protrusion 2321 of the rocker arm base 232 is embedded in the second limiting notch 213, the rocker arm base 232 is further away from the limiting hole 211, and the limiting piece 221 of the rocker arm 22 can be embedded in the limiting hole 211 to realize the storage of the rocker arm 22. When not in use, pressing down on the limiting protrusion 2321 of the rocker arm 22 to the second limiting notch 213 activates the knob mode, locking the rocker arm 22 inside the housing 1 to prevent accidental triggering. When needed, it can be ejected to return to rocker arm mode. This maintains the watch's integrated appearance while significantly improving reliability.

[0039] Furthermore, the adjusting component 23 also includes a first elastic element 233, a second elastic element 234, and a third elastic element 235. The first elastic element 233 is located between the limiting piece 221 and the inner wall of the housing 1, so that the rocker arm 22 elastically abuts against the rocker arm base 232. The second elastic element 234 is located between the end of the driving inner housing 231 away from the rocker arm base 232 and the limiting outer housing 21, ensuring that the driving inner housing 231 elastically abuts against the rocker arm base 232. The third elastic element 235 elastically abuts against the end of the rocker arm base 232 away from the rocker arm 22, and the rocker arm base 232 can rotate relative to the third elastic element 235. The elastic force of the third elastic element 235 is greater than that of the first elastic element 233 and the second elastic element 234. The sum of the elastic forces of the first elastic element 233 and the second elastic element 234 is such that when the pressing force of the rocker arm 22 is released, the third elastic element 235 can overcome the elastic forces of the first elastic element 233 and the second elastic element 234, so that the limiting protrusion 2321 of the rocker arm base 232 is embedded in the first limiting notch 212 or the second limiting notch 213; the drive inner shell 231 is provided with a plurality of first guide slopes 2311 at intervals along the circumference at one end near the rocker arm base 232, and the limiting protrusion 2321 is provided with a second guide slope 2322 that cooperates with the first guide slope 2311. When the limiting protrusion 2321 is embedded in the first limiting notch 212 and the second limiting notch 213, the second guide slope 2322 abuts against the middle position of the first guide slope 2311. For example, when the rocker arm 22 is in a swingable state, the limiting protrusion 2321 is embedded in the first limiting notch 212. Pressing the rocker arm 22 causes the rocker arm base 232 to move away from the limiting hole 211. Under the elastic force of the second elastic member 234, the second guide slope 2322 always abuts against the middle position of the first guide slope 2311. After the rocker arm 22 drives the limiting protrusion 2321 to disengage from the first limiting notch 212, the second guide slope 2321... 322 begins to rotate under the guidance of the first guide slope 2311 until the second guide slope 2322 abuts against the end of the first guide slope 2311 away from the rocker base 232, so that the limiting protrusion 2321 aligns with the second limiting notch 213. Then, the rocker 22 is stopped from being pressed, and the limiting protrusion 2321 is embedded in the second limiting notch 213 by the elastic force of the third elastic member 235. At this time, the limiting piece 221 of the rocker 22 is located in the limiting hole 211, and the rocker 22 cannot swing. Similarly, when the rocker 22 is pressed and released again, the limiting protrusion 2321 moves from the second limiting notch 213 to the first limiting notch 212. At this time, the limiting piece 221 of the rocker 22 is located in the swing gap 12, and the rocker 22 can swing. It should be noted that when the rocker arm 22 is in its retracted state, the limiting piece 221 always slides within the limiting hole 211 during the pressing of the rocker arm 22, preventing the rocker arm 22 from tilting. In other embodiments, the first elastic element 233 can also be omitted, and the rocker arm 22 can be directly connected to the rocker arm base 232.

[0040] In this embodiment, the first elastic element 233, the second elastic element 234 and the third elastic element 235 are all springs. One end of the third elastic element 235 elastically abuts against the rocker base 232, and the other end elastically abuts against the base 236 fixed in the housing 1.

[0041] Preferably, a third guide slope 214 that cooperates with the second guide slope 2322 is provided at the opening of the first limiting notch 212 and the second limiting notch 213. When the limiting protrusion 2321 disengages from the first limiting notch 212 and the second limiting notch 213, the second guide slope 2322 begins to rotate under the guidance of the first guide slope 2311. The second guide slope 2322 abuts against the end of the first guide slope 2311 away from the rocker base 232, releasing the rocker 22. The second guide slope 2322 can then be embedded in the first limiting notch 212 or the second limiting notch 213 under the guidance of the third guide slope 214, improving operational reliability.

[0042] In this embodiment, there are four limiting protrusions 2321, four first limiting notches 212, and four second limiting notches 213; and eight first guide slopes 2311. Each time the joystick 22 is pressed, the joystick base 232 rotates 45 degrees.

[0043] In this embodiment, a second through hole 2313 is provided at one end of the drive inner shell 231 near the second elastic member 234. The drive inner shell 231 is provided with a receiving cavity, and the rocker arm 22 passes through the second through hole 2313 and extends into the receiving cavity. The end of the drive inner shell 231 near the rocker arm base 232 is serrated, and the serration includes eight serrated grooves. One sidewall of the serrated groove is a first guide slope 2311. The first limiting notch 212 is elongated, and a third guide slope 214 is provided at the opening of the first limiting notch 212 near the previous second limiting notch 213. The second limiting notch 213 is triangular, and one sidewall of the second limiting notch 213 is the third guide slope 214, while the other sidewall extends along the axial direction of the limiting hole 211.

[0044] In this embodiment, the inner wall of the limiting shell 21 is provided with a plurality of guide grooves 215 at intervals along the circumference, and the outer wall of the driving inner shell 231 is provided with a plurality of guide protrusions 2312 at intervals along the circumference. The guide protrusions 2312 are slidably connected to the guide grooves 215, thereby enabling the driving inner shell 231 to be slidably connected to the limiting shell 21 and unable to rotate relative to it, and enabling the rocker base 232 to rotate under the guidance of the first guide inclined surface 2311.

[0045] In this embodiment, there are two joystick assemblies 2, spaced apart on one side of the housing 1. This enables dual-joystick control of the drone, simplifying the operation logic: users do not need to memorize complex compound operations, such as "left hand for lateral movement, right hand for elevation and steering," lowering the learning curve. It also reduces hand fatigue: prolonged operation with the rotating crown can cause fatigue; the dual joysticks 22 distribute the pressure, making it suitable for extended flights. The dual-joystick design, by separating control dimensions and supporting parallel operation, significantly improves the efficiency, accuracy, and comfort of drone control, making it particularly suitable for professional aerial photography and complex environment operations. Furthermore, a well-designed human-computer interaction system further optimizes the user experience.

[0046] Furthermore, the joystick assembly 2 also includes a waterproof component 24, which is disposed between the joystick 22 and the joystick base 232. The waterproof component 24 has a sealing groove 241, and one end of the joystick 22 near the joystick base 232 is sealed to the opening of the sealing groove 241. A circuit board is disposed inside the sealing groove 241. The user can operate the joystick 22 to move it in four directions (forward, backward, left, and right) to generate control signals on the circuit board, thereby controlling the drone to perform corresponding operations and achieving drone control.

[0047] Furthermore, the bottom of the sealing groove 241 is provided with a first wiring hole 242, and the rocker base 232 is provided with a second wiring hole 2323. The waterproof component 24 is sealed against the end face of the second wiring hole 2323. The circuit board's wiring harness passes through the first wiring hole 242 and the second wiring hole 2323 to enable the circuit board to conduct electricity. The function of the waterproof component 24 is to prevent water or other liquids from entering the sealing groove 241 and affecting the normal operation of the circuit board, thus helping to extend the watch's service life. When water or other liquids enter the housing 1, they are blocked by the waterproof component 24 and will not flow into the first wiring hole 242 and the second wiring hole 2323. Simply inverting the housing 1 will allow the water or other liquids to be poured out.

[0048] Preferably, a main board is provided inside the crown, which is electrically connected to the circuit board. The main board is equipped with an antenna for transmitting signals with the drone. When the user wears the watch and faces it roughly forward, the antenna can be roughly oriented towards the drone, improving the signal transmission effect. The two rocker assemblies 2 are equipped with GPS antennas, which are directional antennas. When the watch is facing the person directly in front, its normal direction is roughly oriented towards the satellite, which is beneficial for receiving satellite signals.
