Description

Technical Field

[0001] This invention belongs to the field of smart ring technology, and in particular relates to a smart ring and a smart ring set. Background Technology

[0002] Smart rings are wearable devices worn on the fingers. Due to their small size, portability, and ease of operation, they have been widely used in health monitoring, information reminders, and pedometer functions, becoming an indispensable portable device in daily smart living. When designing a smart ring, the charging port layout needs to balance aesthetics and practicality, but current technology struggles to achieve this balance.

[0003] Some smart rings, for aesthetic reasons, design the charging port to protrude from the inside of the ring. However, this protruding port will come into contact with and rub against the skin of the finger, reducing wearing comfort. To improve comfort, some smart rings use a button-type hidden design, storing the charging port inside to avoid direct contact with the skin. However, this design requires an additional operation to reveal the port, increasing the charging steps and making the operation cumbersome. Summary of the Invention In view of this, the present invention provides a smart ring and a smart ring set, aiming to solve the problem that it is difficult to balance aesthetics, wearing comfort and charging convenience in the existing smart ring charging interface design.

[0004] The technical solution of this invention is implemented as follows: This invention provides a smart ring, comprising a ring-shaped body and a power receiving assembly. The inner surface of the ring-shaped body is recessed with a relief groove, and the bottom of the relief groove has a through hole communicating with the inner cavity of the ring-shaped body. The power receiving assembly is disposed within the ring-shaped body and includes a power receiving post extending from the through hole into the relief groove, having an inner end located within the inner cavity of the ring-shaped body and an outer end located outside the inner cavity of the ring-shaped body. The power receiving post is extendable and retractable along the depth direction of the through hole. The device has two states: an extended state protruding from the inner ring of the annular body and a retracted state retracted into the recess; wherein, an elastic element is provided in the inner cavity of the annular body, the elastic element being located between the charging post and the annular body, for elastically restoring the charging post to the retracted state; and a first magnetic attraction part is provided at the outer end of the charging post; the first magnetic attraction part is used to magnetically attract with a second magnetic attraction part on the side of the charging post to overcome the elastic force of the elastic element, so that the charging post is in the extended state and connected to the charging post.

[0005] In one embodiment, the inner end of the power contact post is provided with a laterally protruding protrusion; the elastic element includes a spring, which is sleeved on the power contact post, with one end abutting against the protrusion and the other end abutting against the inner edge of the through hole.

[0006] In one embodiment, the first magnetic attraction part includes a magnet for magnetic attraction with a second magnetic attraction part configured as an electromagnet on the charging post.

[0007] In one embodiment, the outer end face of the terminal post includes a positive electrode contact area and a negative electrode contact area spaced apart, and the magnet is embedded in the spaced area between the positive electrode contact area and the negative electrode contact area.

[0008] In one embodiment, one of the positive electrode contact area and the negative electrode contact area is annular and the other is circular, and the magnet has an annular structure; the positive electrode contact area, the negative electrode contact area, and the outer end face of the magnet are arranged concentrically.

[0009] In one embodiment, a first marking portion is provided on one end face of the annular body at the position corresponding to the clearance groove.

[0010] In one embodiment, a rubber plug is provided at the opening of the relief groove. One end of the rubber plug is a fixed end and the other end is an open end. The fixed end is connected to the annular body, and the open end can be rotated around the fixed end to open or close the relief groove.

[0011] This invention also provides a smart ring set, comprising a smart ring and a charging case. The charging case includes a charging base and a charging post disposed at the top of the charging base. A second magnetic part is provided on the side of the charging post corresponding to the first magnetic part of the charging post. When the first magnetic part and the second magnetic part are magnetically attracted, the elastic element is compressed, and the charging post switches from a retracted state to an extended state, so that the outer end of the charging post is connected to the side of the charging post. When the first magnetic part separates from the second magnetic part, the elastic element at least partially recovers its elasticity, so that the charging post switches from the extended state back to the retracted state, and the outer end of the charging post retracts into the recessed groove. The smart ring includes a ring-shaped body and a charging assembly. The inner surface of the ring-shaped body is recessed with a recessed groove, and the bottom of the recessed groove has a connection to the ring. The main body has a through hole in its inner cavity; the power receiving assembly is disposed within the annular main body, the power receiving assembly includes a power receiving post, the power receiving post extends from the through hole into the relief groove, and has an inner end located within the inner cavity of the annular main body and an outer end located outside the inner cavity of the annular main body; the power receiving post is telescopically arranged along the depth direction of the through hole, having an extended state protruding into the relief groove in the inner ring direction of the annular main body, and a retracted state retracted into the relief groove; wherein, the inner cavity of the annular main body is provided with an elastic member, the elastic member being located between the power receiving post and the annular main body, for elastically restoring the power receiving post to the retracted state, and the outer end of the power receiving post is provided with a first magnetic attraction part; the first magnetic attraction part is used to magnetically attract with a second magnetic attraction part on the side of the charging post to overcome the elastic force of the elastic member, so that the power receiving post is in the extended state and connected to the charging post.

[0012] In one embodiment, a second marking portion is provided on the peripheral sidewall of the charging column corresponding to the position of the second magnetic part.

[0013] In one embodiment, the peripheral sidewall of the charging post is provided with a plug-in groove, the edge area of ​​the plug-in groove is an inclined guide surface, the guide surface gradually narrows from the outside to the inside, so as to guide the outer end of the charging post to slide into the plug-in groove, so that the outer end of the charging post is connected to the charging post.

[0014] This invention provides a smart ring that utilizes a first magnetic attraction at the outer end of the charging post, which engages with a second magnetic attraction on the side of the charging post. The magnetic force automatically drives the charging post to overcome the elastic force of an elastic element, switching it from a retracted state to an extended state, thus achieving connection with the charging post. This eliminates the need for manual button operation or plugging / unplugging, greatly simplifying the charging process. When charging is complete or the ring separates from the charging post, the elastic force automatically returns the charging post to its retracted state, concealing its outer end within a recessed groove. This avoids the friction between the ring and the skin of the fingers that occurs with traditional protruding interfaces during daily wear, significantly improving wearing comfort. Furthermore, the concealed design of the charging post in the non-charging state ensures the flatness of the inner surface of the ring body and maintains the overall aesthetic appeal.

[0021] Smart rings are wearable devices worn on the fingers. Due to their small size, portability, and ease of use, they have been widely used in health monitoring, information reminders, and pedometer functions, becoming an indispensable portable device in daily smart living. When designing a smart ring, the charging port layout needs to balance aesthetics and practicality, but current technology struggles to achieve this balance. Some smart rings, for aesthetic reasons, design the charging port to protrude from the inside of the ring, but this protrusion causes contact and friction with the skin, reducing wearing comfort. To improve comfort, some smart rings use a button-style hidden design, concealing the charging port inside to avoid direct skin contact. However, this design requires additional steps to access the port, increasing the charging process and making it more cumbersome. In view of this, embodiments of the present invention provide a smart ring and a smart ring set, aiming to solve the problem that it is difficult to balance aesthetics, wearing comfort and charging convenience in the existing smart ring charging interface design.

[0022] Please see Figure 1 and Figure 2 The smart ring 100 includes a ring-shaped body 1 and a power-connecting component 2. The ring-shaped body 1 serves as the basic structure of the smart ring 100. The inner surface 11 of the ring-shaped body 1 has a recessed groove 111, which provides space for the retraction of the power-connecting post 21 in the non-working state. The bottom of the recessed groove 111 has a through hole 1111 communicating with the inner cavity 10 of the ring-shaped body 1. This through hole 1111 not only guides the extension and retraction of the power-connecting post 21 but also allows the power-connecting post 21 to pass through the wall of the ring-shaped body 1, thus connecting the inner cavity 10 with the outside.

[0023] The charging assembly 2, as the core component for enabling the charging function of the smart ring 100, is located within the inner cavity 10 of the annular body 1 to ensure good protection and maintain the integrity of the ring's appearance. The charging assembly 2 includes a charging post 21, which extends from the through hole 1111 into the recess 111. Its two ends are an inner end 211 located within the inner cavity 10 of the annular body 1 and an outer end 212 located outside the inner cavity 10 of the annular body 1. The charging post 21 is extendable along the depth direction of the through hole 1111, allowing it to operate in two states: one is an extended state protruding into the recess 111 towards the inner ring of the annular body 1 (e.g.,...). Figure 4 and Figure 5 As shown), at this time, the outer end 212 of the charging post 21 is exposed and can be connected to the external charging structure; another is the retracted state into the relief groove 111 (as shown). Figure 1 and Figure 2 As shown in the figure, at this time, the outer end 212 of the power connection post 21 does not protrude from the inner side 11 of the ring body 1, effectively avoiding direct contact and friction with the skin during daily wear.

[0024] To achieve automatic reset of the contact post 21, an elastic element 3 is provided in the inner cavity 10 of the annular body 1. This elastic element 3 is located between the contact post 21 and the annular body 1, and its main function is to elastically reset the contact post 21 to its retracted state. For details, please refer to... Figure 1 and Figure 2 When the external charging structure separates from the charging post 21, the elastic restoring force of the elastic member 3 pushes the charging post 21 to retract inward until its outer end 212 is completely hidden in the recess 111. The outer end 212 of the charging post 21 is provided with a first magnetic attraction part 2121, the function of which is to interact with the second magnetic attraction part 2011 on the side of the charging post 201 (e.g., ...). Figure 6 (As shown) Magnetic attraction. Please refer to... Figure 4 and Figure 5 When the smart ring 100 needs to be charged, it connects to the first magnetic part 2121 and the second magnetic part 2011 (e.g., Figure 6 The magnetic attraction generated between the two (as shown) overcomes the elastic force of the elastic element 3, pulling the charging post 21 from the retracted state to the extended state, thereby connecting the outer end 212 of the charging post 21 with the charging post 201 to achieve the transmission of electrical energy. This design, which controls the extension and retraction of the charging post 21 through magnetic attraction, eliminates the need for additional mechanical operations by the user, greatly simplifying the charging process.

[0025] Please combine Figure 6In practical use, when a user needs to charge the smart ring 100, they simply place the smart ring 100 over the charging post 201, ensuring that the first magnetic part 2121 of the outer end 212 of the charging post 21 corresponds to the second magnetic part 2011 on the side of the charging post 201. At this time, the magnetic attraction between the first magnetic part 2121 and the second magnetic part 2011 overcomes the elastic force of the elastic element 3 in the inner cavity 10 of the annular body 1, pulling the charging post 21 outward along the depth direction of the through hole 1111, switching it from a retracted state to an extended state. After the charging post 21 extends, its outer end 212 contacts the side of the charging post 201 and establishes a connection, thus initiating charging. During the charging process, due to the continuous action of the magnetic attraction and the guiding effect of the through hole 1111, the charging post 21 remains in the extended state, ensuring stable charging. When charging is complete or the user needs to remove the smart ring 100, simply remove the smart ring 100 from the charging post 201. At this time, the first magnetic part 2121 separates from the second magnetic part 2011, and the magnetic attraction disappears. The elastic element 3 is no longer overcome by the magnetic attraction, and its own elastic restoring force will push the charging post 21 back towards the inner cavity 10 of the annular body 1, causing the charging post 21 to switch from the extended state back to the retracted state. The outer end 212 of the charging post 21 retracts back into the relief groove 111 and no longer protrudes from the inner side 11 of the annular body 1. This design allows the charging post 21 to be hidden in the relief groove 111 when the smart ring 100 is not charging, avoiding direct contact and friction between the charging post 21 and the skin of the finger during daily wear.

[0026] In summary, the smart ring 100 provided in this embodiment of the invention includes an annular body 1 and a power receiving component 2. The inner surface 11 of the annular body 1 is recessed with a relief groove 111, and the bottom of the relief groove 111 has a through hole 1111 communicating with the inner cavity 10 of the annular body 1. The power receiving component 2 is disposed within the annular body 1 and includes a power receiving post 21. The power receiving post 21 extends from the through hole 1111 into the relief groove 111 and has an inner end 211 located within the inner cavity 10 of the annular body 1 and an outer end 212 located outside the inner cavity 10 of the annular body 1. The power receiving post 21 can extend along the depth direction of the through hole 1111. The telescopic design includes an extended state protruding into the inner ring of the annular body 1 through a recessed groove 111, and a retracted state retracting into the recessed groove 111. An elastic element 3 is provided within the inner cavity 10 of the annular body 1, located between the charging post 21 and the annular body 1, to elastically reset the charging post 21 to the retracted state. A first magnetic attraction portion 2121 is provided at the outer end 212 of the charging post 21. The first magnetic attraction portion 2121 is magnetically attracted to the second magnetic attraction portion 2011 on the side of the charging post 201 to overcome the elastic force of the elastic element 3, allowing the charging post 21 to be in the extended state and connected to the charging post 201.

[0027] This invention, through a first magnetic attraction part 2121 provided at the outer end 212 of the charging post 21, which cooperates with the second magnetic attraction part 2011 on the side of the charging post 201, utilizes magnetic attraction to automatically drive the charging post 21 to overcome the elastic force of the elastic member 3, switching it from a retracted state to an extended state, thus achieving connection with the charging post 201. This eliminates the need for manual operation of buttons or plugging / unplugging interfaces, greatly simplifying the charging process. When charging is complete or the ring separates from the charging post 201, the elastic force of the elastic member 3 automatically resets the charging post 21 to the retracted state, hiding its outer end 212 within the recessed groove 111. This avoids the contact and friction between the traditional protruding interface and the skin of the fingers during daily wear, significantly improving wearing comfort. Simultaneously, the concealed design of the charging post 21 in the non-charging state also ensures the flatness of the inner side 11 of the ring body 1 and the overall aesthetic appearance.

[0028] In some embodiments, please refer to Figure 2 and Figure 5 In order to enable the power connection post 21 to extend and retract stably and improve the installation reliability of the elastic element 3, a laterally protruding protrusion 2111 is provided at the inner end 211 of the power connection post 21; the elastic element 3 includes a spring 31, which is sleeved on the power connection post 21, with one end abutting against the protrusion 2111 and the other end abutting against the inner edge of the through hole 1111.

[0029] The protrusion 2111 provides a stable support point for the spring 31, reducing the spring 31's offset during compression and reset. The spring 31 is sleeved on the contact post 21, allowing its elastic force to act evenly on the contact post 21, improving the smoothness of the contact post 21's extension and retraction. The inner edge of the through hole 1111 serves as the abutment surface for the other end of the spring 31. The annular structure of the inner edge limits the spring 31, simplifying the installation structure of the elastic element 3 and enhancing overall stability and durability. When the contact post 21 extends outward under magnetic attraction, the protrusion 2111 compresses the spring 31, allowing the spring 31 to store elastic potential energy. When the magnetic attraction disappears, the spring 31 releases its elastic potential energy, pushing the protrusion 2111 to retract the contact post 21 into the relief groove 111. This structural design is simple and compact, effectively realizing the automatic extension, retraction, and reset functions of the contact post 21.

[0030] In some embodiments, please continue reading Figure 2 and Figure 5 In order to form a stable and controllable magnetic attraction between the first magnetic attraction part 2121 and the second magnetic attraction part 2011 on the charging post 201, the first magnetic attraction part 2121 includes a magnet to magnetically attract the second magnetic attraction part 2011 on the charging post 201, which is configured as an electromagnet.

[0031] Specifically, the outer end 212 of the charging post 21 is fixedly equipped with the aforementioned magnet, which can be a permanent magnet structure, capable of maintaining magnetic attraction for a long time. Correspondingly, an electromagnet is assembled on the side of the charging post 201. This electromagnet can be electrically connected to the control circuit of the charging base 202 to achieve controllable power on / off operation. When the smart ring 100 needs to be charged, the charging base 202 controls the electromagnet to be energized, and the electromagnet generates magnetism, forming a magnetic attraction between it and the magnet at the outer end 212 of the charging post 21. This attraction can overcome the elastic force of the elastic element 3 in the inner cavity 10 of the annular body 1, driving the charging post 21 to move along the depth direction of the through hole 1111 towards the inner ring direction of the annular body 1, switching from a retracted state into the relief groove 111 to an extended state protruding from the relief groove 111, thereby achieving stable connection between the charging post 21 and the charging post 201, and ensuring smooth charging.

[0032] Once charging is complete, the charging base 202 de-energizes the electromagnet, causing its magnetism to disappear. This releases the magnetic attraction force, allowing the elastic restoring force of the elastic element 3 to be released, pushing the contact post 21 to move in the opposite direction and retract back into the recess 111. This ensures that the contact post 21 does not protrude from the inner side 11 of the ring-shaped body 1, guaranteeing wearing comfort and a clean product appearance. The combined design of the magnet and electromagnet improves the reliability of the magnetic attraction force, enabling accurate extension and retraction of the contact post 21. Furthermore, the on / off control of the electromagnet allows for on-demand activation and deactivation of the magnetic attraction, enhancing the automation and ease of use of the smart ring 100's charging operation.

[0033] In some embodiments, please continue reading Figure 2 and Figure 5 In order to improve the stability of power connection and the reliability of magnetic alignment, and reduce the mutual interference between the contact area and the magnetic components, the outer end 212 surface of the power connection post 21 includes a positive contact area surface 2122 and a negative contact area surface 2123 that are spaced apart, and the magnet is embedded in the spaced area between the positive contact area surface 2122 and the negative contact area surface 2123.

[0034] The positive contact area 2122 and the negative contact area 2123 are respectively used to contact the positive contact 2012 and the negative contact 2013 on the side of the charging post 201 to achieve bidirectional current transmission. A magnet is embedded in the space between these two contact areas, so that the positive contact area 2122, the negative contact area 2123, and the magnet are separated and do not interfere with each other. On the one hand, the two contact areas can accurately match the corresponding contacts on the side of the charging post 201, independently achieving positive and negative polarity conduction, reducing the risk of misalignment and short circuit, and improving the stability of bidirectional current transmission during charging and data transmission (if any). On the other hand, the magnet embedded in the space can form a stable magnetic attraction force with the second magnetic attraction part 2011 on the side of the charging post 201, reliably driving the charging post 21 to overcome the elastic force of the elastic member 3 and achieve accurate alignment.

[0035] To further optimize the structural layout of the outer end 212 of the power connection post 21 and improve the accuracy of the connection with the charging post 201, one of the positive contact area surface 2122 and the negative contact area surface 2123 is annular and the other is circular, and the magnet is annular; the positive contact area surface 2122, the negative contact area surface 2123 and the outer end 212 surface of the magnet are arranged concentrically.

[0036] For example, the positive contact area 2122 is designed as an outermost ring, and its ring structure can increase the contact area with the positive contact 2012 of the charging post 201, so that stable contact can still be guaranteed even when there is a slight radial offset between the charging post 201 and the power connection post 21; the negative contact area 2123 is located on the inner side and has a circular structure, which can accurately correspond to the negative contact 2013 at the center of the charging post 201; while the magnet adopts a ring structure, which is fitted on the outer periphery of the circular negative contact area 2123 and located on the inner periphery of the annular positive contact area 2122. All three are arranged concentrically with the same center. This concentric design allows the terminal post 21 to extend smoothly along the axial direction when subjected to magnetic attraction, reducing skew caused by uneven force and improving the accuracy of the alignment between the positive contact area 2122 and the positive contact 2012 of the charging post 201, and between the negative contact area 2123 and the negative contact 2013 of the charging post 201. This further enhances the electrical connection stability and alignment accuracy during charging. Simultaneously, the combination of annular and circular layouts makes the outer end 212 of the terminal post 21 more compact, making full use of limited space and balancing functionality and structural rationality.

[0037] In some embodiments, please refer to Figure 1 and Figure 4 In order to facilitate users to quickly locate the position of the power connection post 21 and improve the convenience of aligning the power connection post 21 with the charging post 201 during charging, a first marking part 12 is provided on one end face of the annular body 1 at the position corresponding to the clearance groove 111.

[0038] The first marking part 12 can take the form of color marking, pattern engraving, or micro-embossed texture. For example, a ring-shaped color band that contrasts sharply with the main body color can be set at the edge of the end face of the ring body 1, or an arrow symbol can be engraved to point to the location of the clearance groove 111. It can also be designed with fine concave and convex textures to provide tactile feedback. When the user needs to put the smart ring 100 on the outside of the charging post 201 for charging, there is no need to carefully observe the inner side 11 of the ring to find the position of the charging post 21. The user can quickly determine the position of the clearance groove 111 and the charging post 21 by visually recognizing the color or pattern of the first marking part 12, or by touching the texture with their fingers. This allows the user to accurately align the first magnetic part 2121 of the outer end 212 of the charging post 21 with the second magnetic part 2011 on the side of the charging post 201, effectively reducing charging delays or poor contact caused by alignment deviations, and further improving the convenience of charging operation and user experience.

[0039] In some embodiments, please refer to Figure 3 In order to effectively protect the relief groove 111 and the power terminal 21 inside the groove, a rubber plug 4 is provided at the opening of the relief groove 111. One end of the rubber plug 4 is a fixed end and the other end is an open end. The fixed end is connected to the annular body 1, and the open end can be rotated around the fixed end to open or close the relief groove 111.

[0040] The rubber stopper 4 possesses excellent flexibility, wear resistance, and waterproof performance, allowing it to tightly conform to the contour of the recess 111, preventing sweat, dust, and other foreign objects from entering the recess 111 during daily wear. When the smart ring 100 finishes charging, the user rotates the rubber stopper 4, causing its open end to cover and close the recess 111. At this time, the outer surface of the rubber stopper 4 smoothly transitions to the inner surface 11 of the ring body 1, preventing indirect contact between the outer end 212 of the charging post 21 and the skin, and enhancing the ring's waterproof and dustproof capabilities. When charging is needed, the user simply flips the open end of the rubber stopper 4 to expose the charging post 21 inside the recess 111, without affecting the magnetic attraction between the first magnetic part 2121 and the second magnetic part 2011 or the extension of the charging post 21. The fixed end of the rubber stopper 4 can be integrated with the ring body 1 through integral molding or detachable connection, and its open end edge can be designed with a micro-flange for easy finger manipulation, improving ease of operation. This rubber plug 4 design provides additional physical protection for the power connection post 21 without increasing the complexity of the charging process, extending the service life of the power connection component 2, and also improving wearing comfort and overall sealing when not charging.

[0041] This invention also provides a smart ring set.

[0042] Please see Figures 1 to 6The smart ring set includes a charging case 200 and a smart ring 100 provided in any of the above embodiments. The charging case 200 includes a charging base 202 and a charging post 201 disposed at the top of the charging base 202. The structure of the charging post 201 is adapted to the power receiving component 2 of the smart ring 100. Its side is provided with a second magnetic part 2011 corresponding to the first magnetic part 2121 of the outer end 212 of the power receiving post 21, and a positive contact 2012 and a negative contact 2013 respectively connected to the positive contact area surface 2122 and the negative contact area surface 2123 of the outer end 212 of the power receiving post 21.

[0043] When the smart ring 100 is fitted onto the charging post 201, the second magnetic part 2011 on the side of the charging post 201 attracts the first magnetic part 2121 on the outer end 212 of the charging post 21, causing the charging post 21 to extend from its retracted state against the elastic force of the elastic member 3. This causes the positive contact area 2122 of the outer end 212 of the charging post 21 to contact the positive contact 2012 of the charging post 201, and the negative contact area 2123 to contact the negative contact 2013 of the charging post 201, thus forming a complete charging circuit to charge the battery inside the smart ring 100.

[0044] The charging dock 202 is equipped with an interface 2021 for connecting to an external circuit or power source, as well as a control circuit for controlling the charging process. This control circuit can detect the charging status (such as battery level, charging current, charging voltage, etc.) and automatically cut off the charging circuit after the battery is fully charged to prevent overcharging and ensure charging safety. Preferably, the interface 2021 on the charging dock 202 can be a Type-C interface 2021. This Type-C interface 2021 can be used with common cables such as mobile phone charging cables and computer data cables, eliminating the need for a separate dedicated charger and greatly improving the versatility and portability of the charging dock 202. In daily use, users can directly connect the charging dock 202 with a Type-C data cable used for charging mobile phones to charge the smart ring 100, significantly reducing the number of chargers to carry when traveling and improving ease of use.

[0045] The charging box 200 serves as an intermediary between the smart ring 100 and a household power source during the charging process. To improve charging efficiency, a large coil design can be adopted. By configuring a large coil, the charging power transmission efficiency can be increased, effectively improving the charging speed. At the same time, with the voltage stabilization and current limiting processing of the control circuit, the charging efficiency can be improved while avoiding damage to the smart ring 100 battery caused by voltage and current fluctuations, thus balancing charging speed and battery protection.

[0046] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 6In order to further improve the alignment efficiency between the smart ring 100 and the charging post 201 and facilitate the user to quickly locate the position of the second magnetic part 2011, a second marking part 2014 is provided on the peripheral side wall of the charging post 201 corresponding to the position of the second magnetic part 2011.

[0047] The second marking part 2014 can adopt a design form that echoes the first marking part 12. For example, it can be provided with a ring of raised or recessed textures on the peripheral wall of the charging post 201, which is a different color from the body of the charging post 201, or it can be sprayed with a marking ring of the same color as the first marking part 12 on the smart ring 100. When the user brings the smart ring 100 close to the charging post 201, they can visually observe the position of the second marking part 2014 and align it with the first marking part 12 on the smart ring 100, thereby quickly aligning the first magnetic part 2121 of the outer end 212 of the charging post 21 with the second magnetic part 2011 on the side of the charging post 201. This dual marking design can significantly reduce the difficulty of alignment for the user when wearing the device (especially when visibility is poor). Through dual cues of color, texture, or structure, it guides the user to quickly complete the orientation matching between the smart ring 100 and the charging post 201.

[0048] In some embodiments, please refer to Figure 6 In order to improve the connection stability of the power connection post 21 and the charging post 201, and to improve the smoothness of their alignment, the peripheral side wall of the charging post 201 is provided with a plug groove 2015. The edge area of ​​the plug groove 2015 is an inclined guide surface, which gradually narrows from the outside to the inside to guide the outer end 212 of the power connection post 21 to slide into the plug groove 2015, so that the outer end 212 of the power connection post 21 and the charging post 201 are connected.

[0049] The stability of the connection between the charging post 21 and the charging post 201 directly affects the reliability of the charging process. If there is a misalignment between the two or if there is shaking after the connection, it can easily lead to problems such as poor contact and charging interruption. By opening a plug groove 2015 on the side wall of the charging post 201, the structural dimensions of the plug groove 2015 are adapted to the outer end 212 of the charging post 21. When the outer end 212 of the charging post 21 extends into the groove, the groove wall of the plug groove 2015 can effectively limit the radial movement of the charging post 21, effectively restricting the relative displacement between the charging post 21 and the charging post 201, avoiding loosening of the connection due to external interference or slight shaking during the charging process, and significantly improving the connection stability.

[0050] Meanwhile, considering that there may be a slight positional deviation between the outer end 212 of the connector 21 and the opening of the insertion slot 2015 during the actual alignment process, the edge area of ​​the insertion slot 2015 is set as an inclined guide surface. This guide surface has a smoothly transitioning inclined structure, gradually converging from the outside of the slot to the inside, forming a natural guiding channel. When the connector 21 extends under the magnetic attraction force, even if there is a slight deviation from the slot opening, its outer end 212 will first contact the inclined guide surface, automatically correct its position under the guidance of the guide surface, and smoothly slide into the insertion slot 2015 without the need for repeated manual adjustments by the user.

[0051] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
