Description

Technical Field

[0001] This release belongs to the field of smart wearable technology, and specifically relates to a wireless charging smart ring and its operating method. Background Technology

[0002] With the development of modern electronic technology, smart rings not only serve as decorative accessories but also offer a smarter lifestyle. However, as intelligent devices, smart rings inevitably require electricity. Due to their small size and relatively small battery capacity, battery life is a challenge. Currently, charging smart rings typically requires removing them from the user's finger, which can be inconvenient. While some technologies offer wireless charging options, such as patent application CN2015205586461, which describes a similar method, existing technologies also exist. The circuit structure of this patent application facilitates wireless charging of the smart ring by setting up a wireless charging receiver protection circuit, coils, and batteries; it is waterproof. However, the structure of this patent application is relatively simple, and it does not consider the cost and efficiency issues caused by the number of wireless coils and their placement, nor does it consider that the smart ring still needs to be wirelessly charged at a separate fixed point. Patent application CN201610617185X provides a modular connection structure for a smart ring, which improves the smart ring's battery life by providing a battery swapping method on the side of the ring. This is an effective way to improve battery life, but it has certain structural requirements, and the waterproofing issue is also more difficult to handle due to the swapping structure. Summary of the Invention

[0003] This invention discloses a wireless charging smart ring, comprising: a first annular shell and a second annular shell, the second annular shell being disposed on the outer ring of the first annular shell and nested therewith, and the second annular shell being rotatable along the first annular shell; at least two wireless charging coils being spaced apart on the inner surface of the second annular shell; metal contacts being spaced apart on the second annular shell; and a metal sheet being provided on the first annular shell; when the second annular shell is pressed down, the metal contacts, when in the correct position, can contact and conduct electricity with the metal sheet.

[0004] The wireless charging smart ring described above has a battery module, NFC, a wireless communication module, and a processor housed in the first annular shell.

[0005] In the aforementioned wireless charging smart ring, the metal contacts are initially disconnected from the metal plate. The number of metal contacts is the same as the number of wireless charging coils, and the metal contacts and the wireless charging coils are arranged on a straight line with the same radius as the center of a circle.

[0006] The wireless charging smart ring, wherein the first annular shell includes a first annular body, a first protrusion, a second protrusion, a third protrusion, a fourth protrusion, and a spring-loaded component. The first annular body is a ring with a certain width. The lower surface of the ring contacts the user's finger wearing the smart ring. The first, second, third, and fourth protrusions are evenly arranged on the upper surface of the ring. The first, second, third, and fourth protrusions are parallel to each other and perpendicular to the upper surface of the ring. The first and fourth protrusions are perpendicularly positioned at the two outermost edges of the upper surface of the ring in the width direction. The second and third protrusions are equally spaced between the first and fourth protrusions. A first spring-loaded component is provided between the first and second protrusions, and a second spring-loaded component is provided between the third and fourth protrusions. The metal sheet is disposed between the second and third protrusions. Through holes are provided on the sides of the second and third protrusions, and the through holes are arranged in a ring around the second and third protrusions. The through holes are used to facilitate the nesting of the second annular housing. The battery module, NFC, wireless communication module, and processor are disposed inside the first annular body, and the battery module is connected to the metal contacts.

[0007] The wireless charging smart ring, wherein the second annular shell includes a second annular body, a first nesting portion and a second nesting portion; the first nesting portion includes a first vertical plate and a first nesting protrusion disposed at the front end of the first vertical plate, the second nesting portion includes a second vertical plate and a second nesting protrusion disposed at the front end of the second vertical plate, the first nesting protrusion is disposed in the through hole of the second protrusion, the second nesting protrusion is disposed in the through hole of the third protrusion, and the metal contact is disposed on the lower surface of the second annular body.

[0008] The operation method of the wireless charging smart ring as described in any of the above includes the following steps:

[0009] When the smart ring is brought close to the terminal, the terminal reads the smart ring via NFC. The terminal sends a successful read signal to the processor of the smart ring. After receiving the successful read signal from the terminal, the processor sends a vibration control signal to control the smart ring to vibrate to alert the user.

[0010] After receiving the vibration alert, the user squeezes the smart ring forcefully against the terminal, causing the portion of the smart ring's second annular shell that contacts the terminal to move closer to the first annular shell. Once the portion of the second annular shell that contacts the terminal moves closer to the first annular shell, the rebound component sends a squeezing signal to the processor. Upon receiving the squeezing signal, the processor sends a display command to the terminal. Upon receiving the display command, the terminal displays the position of the wireless charging coil of the smart ring on its screen and provides a specific rotation reference value based on the position of the wireless charging coil.

[0011] The user rotates the second annular shell according to the rotation reference value, and then continues to move the part of the second annular shell of the smart ring that contacts the terminal towards the first annular shell, so that the metal contacts on the same radius of the wireless charging coil are connected to the metal plate. After the connection is completed, a connection completion signal is sent to the processor.

[0012] After receiving the connection completion signal, the processor sends a wireless charging start signal to the terminal. After receiving the wireless charging start signal, the terminal wirelessly charges the smart ring through the wireless power supply coil.

[0013] The operation method of the wireless charging smart ring as described in any of the above claims, wherein the smart ring includes a micro-driving component, includes the following steps:

[0014] When the smart ring is brought close to the terminal, the terminal reads the smart ring via NFC. The terminal sends a successful read signal to the processor of the smart ring. After receiving the successful read signal from the terminal, the processor sends a vibration control signal to control the smart ring to vibrate to alert the user.

[0015] After receiving the vibration alert, the user squeezes the smart ring forcefully against the terminal, causing the portion of the smart ring's second annular shell that contacts the terminal to move closer to the first annular shell. Once the portion of the second annular shell that contacts the terminal moves closer to the first annular shell, the rebound component sends a squeezing signal to the processor. Upon receiving the squeezing signal, the processor sends a display command to the terminal. Upon receiving the display command, the terminal displays the position of the wireless charging coil of the smart ring on its screen and provides a specific rotation reference value based on the position of the wireless charging coil.

[0016] The rotation reference value is directly operated on the terminal's display interface. The terminal transmits the control signal corresponding to the rotation reference value to the processor of the smart ring. After receiving the control signal, the processor controls the micro drive component to rotate. After rotation, the second annular shell is rotated to a suitable position. Then, the part of the second annular shell of the smart ring that contacts the terminal is moved closer to the first annular shell so that the metal contacts on the same radius as the wireless charging coil are connected to the metal plate. After the connection is completed, a connection completion signal is sent to the processor.

[0017] After receiving the connection completion signal, the processor sends a wireless charging start signal to the terminal. After receiving the wireless charging start signal, the terminal wirelessly charges the smart ring through the wireless power supply coil.

[0018] This invention proposes a wireless charging smart ring and its operating method. This invention allows the smart ring to be charged while worn, facilitating extended use. Since smart rings generally require sufficient battery power to function, wireless charging often involves the issue of coil alignment. The technical solution of this invention simplifies coil alignment, improving charging efficiency. Furthermore, because users frequently use their devices, the smart ring can be charged simultaneously, eliminating the inconvenience of removing the ring for charging and enhancing the user experience. One of the main improvements of this invention is that it allows users to charge the smart ring while using the terminal, improving the user experience, facilitating long-term use of the smart ring, and reducing the inconvenience of removing the smart ring for charging. Another important improvement is that it helps users locate and confirm the wireless charging coil during the charging process. When not charging, the wireless charging coil is not connected to the metal plate via metal contacts, avoiding unnecessary interference signals that could interfere with the internal performance of the smart ring. Furthermore, the number of wireless coils does not completely cover the second annular shell, reducing the number of coils used, saving costs, and without adding extra weight to the smart ring. Yet another improvement is that the second annular shell can rotate around the first annular shell, which helps adjust the contact position between the wireless coil and the terminal, improving the wireless charging coupling coefficient and increasing charging efficiency.

[0029] In the aforementioned wireless charging smart ring, the metal contacts are initially disconnected from the metal plate. The number of metal contacts is the same as the number of wireless charging coils, and the metal contacts and the wireless charging coils are arranged on a straight line with the same radius as the center of a circle.

[0030] Preferably, when there are 3, 4, or 6 wireless charging coils, the number of metal contacts is also set to 3, 4, or 6.

[0031] The wireless charging smart ring, wherein the first annular shell includes a first annular body, a first protrusion, a second protrusion, a third protrusion, a fourth protrusion, and a spring-loaded component. The first annular body is a ring with a certain width. The lower surface of the ring contacts the user's finger wearing the smart ring. The first, second, third, and fourth protrusions are evenly arranged on the upper surface of the ring. The first, second, third, and fourth protrusions are parallel to each other and perpendicular to the upper surface of the ring.

[0033] Preferably, the first and fourth protrusions are used to wrap the second annular shell, which can prevent external water from entering the smart ring to a certain extent, and on the other hand, can protect the second annular shell, thus providing good support and protection. The second and third protrusions are used to facilitate the rotation of the second annular shell. In one embodiment of the second annular shell in this application, the second annular shell is rotated by manual operation by the user. The user can directly move the outer surface of the second annular shell to make it rotate along the first annular shell.

[0034] More preferably, a toggle button is provided, which allows the user to rotate the second annular housing along the first annular housing using the toggle button and the rotating shaft.

[0035] More preferably, the second annular housing can be equipped with an automatically rotating operating component, such as a micro drive motor, which can be operated directly on the terminal's display interface. This allows the terminal's control signal to be transmitted to the smart ring's processor. Upon receiving the control signal, the processor controls the micro drive motor to rotate, which in turn rotates the second annular housing to a suitable position, enabling the user to wirelessly charge the smart ring directly.

[0036] like Figure 3 The diagram shown is an embodiment of the operation method of the wireless charging smart ring of the present invention. The operation method of the wireless charging smart ring as described in any of the above claims includes the following steps:

[0037] When the smart ring is brought close to the terminal, the terminal reads the smart ring via NFC. The terminal sends a successful read signal to the processor of the smart ring. After receiving the successful read signal from the terminal, the processor sends a vibration control signal to control the smart ring to vibrate to alert the user.

[0038] After receiving the vibration alert, the user squeezes the smart ring forcefully against the terminal, causing the portion of the smart ring's second annular shell that contacts the terminal to move closer to the first annular shell. Once the portion of the second annular shell that contacts the terminal moves closer to the first annular shell, the rebound component sends a squeezing signal to the processor.

After the connection is completed, a connection completion signal is sent to the processor.

Upon receiving the squeezing signal, the processor sends a display command to the terminal. Upon receiving the display command, the terminal displays the position of the wireless charging coil of the smart ring on its screen and provides a specific rotation reference value based on the position of the wireless charging coil.

[0044] A second annular shell can be configured with an automatically rotating operating component, such as a micro drive motor, which can be operated directly on the terminal's display interface. The terminal's control signal can then be transmitted to the smart ring's processor. Upon receiving the control signal, the processor controls the micro drive motor to rotate, which in turn rotates the second annular shell to a suitable position, allowing the user to wirelessly charge the smart ring directly. Then, the portion of the smart ring's second annular shell that contacts the terminal is moved closer to the first annular shell so that the metal contacts on the same radius as the wireless charging coil connect with the metal plate. Once the connection is complete, a connection completion signal is sent to the processor.

[0045] After receiving the connection completion signal, the processor sends a wireless charging start signal to the terminal. After receiving the wireless charging start signal, the terminal wirelessly charges the smart ring through the wireless power supply coil.
