Description

Technical Field

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

[0002] With the development of wearable smart devices, smart rings have gradually become a new type of smart terminal following smartwatches and smart bracelets due to their advantages of small size, comfortable wear, high concealment, and convenient all-day continuous monitoring. Currently, most smart rings on the market integrate various basic health management functions such as heart rate monitoring, blood oxygen detection, sleep analysis, and activity tracking.

[0003] However, existing smart rings have fixed functions. Typically, a single model of smart ring only has a fixed number of functional modules. The limited space in a smart ring limits the number of functional modules that can be set. This fixed number of functional modules cannot meet the needs of users with different functional preferences, nor can it fulfill users' desire for a single smart ring to have more functions. Furthermore, as the application scenarios for smart rings increase, users are no longer satisfied with functional modules that are only passively detected or controlled by external devices. Users also need functional modules that can be actively triggered by the smart ring itself. Existing technologies do not have designs for functional modules that can be actively triggered. Summary of the Invention

[0004] The main objective of this invention is to propose a smart ring that addresses the technical problems of existing smart rings, such as limited space, the inability of a fixed number of functional modules to meet the needs of users with different functional preferences, the demand for more functions in a single smart ring, and the lack of actively triggered functional modules.

[0005] To achieve the above objectives, the present invention proposes a smart ring, comprising: The ring body has a mounting cavity formed therein, and the ring body has a plurality of assembly slots spaced apart therein at the position corresponding to the mounting cavity, and the plurality of assembly slots are all connected to the mounting cavity. A circuit board assembly, comprising a flexible circuit board and a touch circuit board electrically connected to each other, the flexible circuit board and the touch circuit board extending circumferentially along the mounting cavity and arranged sequentially to form the circuit board assembly circumferentially disposed within the mounting cavity, a plurality of mounting slots being provided corresponding to the flexible circuit board, and a touch module being provided on the touch circuit board; Multiple functional modules, each of which is shaped to match at least one of the assembly slots and is detachably inserted into the assembly slots, and each of the functional modules is able to communicate with the flexible circuit board when inserted into the assembly slot that matches its shape; The ring body has a touch area corresponding to the position of the touch module. The touch module is used to trigger when the touch area is touched and send an instruction to the touch circuit board. The functional module can send a signal to the flexible circuit board or work when it receives the instruction transmitted by the flexible circuit board.

[0006] In one embodiment, each of the functional modules includes a housing and a functional component assembled within the housing. Each housing is shaped to match at least one of the mounting slots and is insertably engaged with the mounting slots. Each of the functional components is conductive to the flexible circuit board when the housing is inserted into the mounting slot that matches its shape. The functional components include an active functional component, a passive functional component, and a triggering functional component. The passive functional component is used to operate when the housing is inserted into the assembly slot that matches its shape and to send a transmission signal to the flexible circuit board. The active functional component is used to operate when the instruction is received. The triggering functional component is used to send a trigger signal to the flexible circuit board when it is triggered.

[0007] In one embodiment, the housing includes an inner sidewall disposed near the inner wall of the annulus and an outer sidewall disposed near the outer wall of the annulus; The active functional components are disposed on the outer side wall, and each active functional component is one of a camera device, a speaker device, a microphone device, and an infrared emitting device; The triggering components are located on the outer side wall, and each triggering component is one of a joystick assembly, a button assembly, a switch assembly, and a trackball device.

[0008] In one embodiment, an antenna module is also integrated on the touch circuit board; The passive functional component, the camera device, and the microphone device are used to transmit the collected data through the flexible circuit board to the antenna module on the touch circuit board and then send it to an external device. The joystick assembly, the button assembly, the switch assembly, and the trackball device are used to emit a trigger signal when triggered. The trigger signal is transmitted to the antenna module on the touch circuit board via the flexible circuit board and then sent to an external device.

[0009] In one embodiment, the inner wall of the ring is provided with clearance holes corresponding to the positions of each of the assembly slots, which communicate with the mounting cavity. The flexible circuit board is provided with positioning holes corresponding to each of the clearance holes, which communicate with the clearance holes. The passive functional component is provided with sensor contacts protruding from the housing toward the inner wall of the ring. When the housing is inserted into the assembly slot that matches its shape, the sensor contacts pass through the positioning holes and extend into the clearance holes.

[0010] In one embodiment, each of the functional modules is provided with a conductive contact, and the flexible circuit board is provided with a connecting contact corresponding to each of the assembly slots. When the functional module is inserted into the assembly slot that matches its shape, the conductive contact is connected to the corresponding connecting contact, so that the functional module is connected to the flexible circuit board.

[0011] In one embodiment, each of the assembly slots is provided with a fixing frame. The inner end and outer end of the fixing frame are respectively a hinge end and a snap-fit ​​end arranged radially along the ring body. The slot opening of the assembly slot is arranged outward. Each of the functional modules has a snap-fit ​​hole on one side corresponding to the snap-fit ​​end. The hinge end is hinged to the bottom wall of the assembly slot. The snap-fit ​​end can swing from the relaxed position toward the position closer to the functional module when the functional module is inserted into the assembly slot through the slot, so as to snap into the snap-fit ​​hole; the snap-fit ​​end can also swing from the snap-fit ​​position to the relaxed position away from the functional module, so as to disengage from the snap-fit ​​hole.

[0012] In one embodiment, the snap-fit ​​end is provided with a snap-fit ​​block protruding toward the mounting groove and a lever extending in a direction away from the mounting groove. The snap-fit ​​block is used to snap into the snap-fit ​​hole, and the lever is used to drive the snap-fit ​​end to swing from the snap-fit ​​position to the release position when pushed in a direction away from the mounting groove, so that the snap-fit ​​end disengages from the snap-fit ​​hole, and pushes the functional module toward the slot through the hinge end to push it away from the mounting groove.

[0013] In one embodiment, the hinge end protrudes towards the assembly groove to form an abutment block, and the functional module has an abutment groove on one side corresponding to the inner wall of the ring. When the functional module is inserted into the assembly groove that matches its shape, the abutment groove abuts against the abutment block and drives the fixing frame to rotate, thereby driving the locking end to swing from the relaxed position to the locking position. The abutment block is also used to swing towards the opening of the assembly groove when the paddle is pushed away from the assembly groove, so as to abut against the abutment groove and push the functional module towards the opening to push it away from the assembly groove.

[0014] In one embodiment, each of the assembly slots is provided with two first magnetic attractors on opposite sides along the extension direction of the ring body, and each of the functional modules is provided with two second magnetic attractors on opposite sides along the circumferential direction of the ring body. The two first magnetic attractors are used to magnetically engage with the two second magnetic attractors respectively after the functional module is inserted into the assembly slot that matches its shape.

[0015] In this invention, multiple mounting slots are formed on the ring body, and each functional module is designed to match the shape of at least one mounting slot and be detachably inserted. This allows users to select different functional modules to insert into the mounting slots according to their preferences or needs, thus customizing the functional modules of the smart ring. Furthermore, different functional modules can be selected for different usage scenarios, improving the applicability of the smart ring. Additionally, a touch module is set on the touch circuit board, and a touch area is set at the corresponding position on the ring body. This allows users to trigger the touch module by touching the touch area, sending commands to the functional modules to actively activate them. This invention, through the detachable insertion design of functional modules and mounting slots, enables the customization and adjustment of the smart ring's functional modules. This satisfies the needs of users with different functional preferences and allows a single smart ring to select different functional modules for different usage scenarios, fulfilling users' needs for more functions within a single smart ring. Simultaneously, the design of the touch module and touch area ensures that some functional components only start working when actively triggered by the user, without requiring additional external devices. This can be achieved simply by touching the touch area on the ring body, satisfying the user's need for functional modules that can be actively triggered by the smart ring.

[0023] Existing smart rings have fixed functions, with each model typically having only a fixed set of functional modules. The limited space in a smart ring restricts the number of these modules. This fixed number of modules fails to meet the diverse functional preferences of different users, and also fails to fulfill users' needs for more advanced features. Furthermore, as the application scenarios for smart rings expand, their functional modules are no longer limited to passive detection types; there are also modules that require active triggering, and existing technologies lack designs capable of such active triggering.

[0024] Please combine Figures 1 to 4 To address the aforementioned issues, this application provides a smart ring 100, comprising a ring body 1, a circuit board assembly 2, and multiple functional modules 3. The ring body 1 has a mounting cavity 11 arranged circumferentially within it, and multiple mounting slots 12 spaced circumferentially from the mounting cavity 11 at positions corresponding to the mounting cavity 11. All mounting slots 12 are connected to the mounting cavity 11. The circuit board assembly 2 includes a flexible circuit board 21 and a touch circuit board 22 electrically connected to each other. The flexible circuit board 21 and the touch circuit board 22 extend circumferentially from the mounting cavity 11 and are arranged sequentially to form a circuit board assembly 2 encircling the mounting cavity 11. Multiple mounting slots 12 are provided corresponding to the flexible circuit board 21, and a touch module is provided on the touch circuit board 22; each functional module 3 matches the shape of at least one mounting slot 12 and is detachably inserted into the mounting slot 12, and each functional module 3 can be connected to the flexible circuit board 21 when inserted into the mounting slot 12 that matches its shape; a touch area 13 is formed in the ring body 1 corresponding to the position of the touch module, and the touch module is used to trigger when the touch area 13 is touched and send an instruction to the touch circuit board 22. The functional module 3 can send a signal to the flexible circuit board 21 or work when it receives an instruction from the flexible circuit board 21.

[0025] In the technical solution of the present invention, by opening multiple assembly slots 12 on the ring body 1 and setting each functional module 3 to be detachably inserted and matched with at least one assembly slot 12, users can select different functional modules 3 to insert into the assembly slots 12 according to their own preferences or needs, thereby realizing the customization of the functional modules 3 of the smart ring 100. Furthermore, different functional modules 3 can be selected according to different usage scenarios, improving the applicability of the smart ring 100. In addition, by setting a touch module on the touch circuit board 22 and setting a touch area 13 at the position of the touch module on the ring body 1, users can trigger the touch module by touching the touch area 13, sending instructions to the functional module 3 to actively trigger the functional module 3 to start working. This invention, through the detachable insertion and assembly of functional module 3 and assembly slot 12, enables the customized adjustment of functional module 3 of the smart ring 100. This satisfies the needs of users with different functional preferences and allows a single smart ring 100 to select different functional modules 3 according to different usage scenarios, thus fulfilling users' needs for more functions in a single smart ring 100. At the same time, through the design of the touch module and touch area, some functional components 32 only start working when actively triggered by the user, and no additional external device control is required. This can be achieved by touching the touch area 13 of the ring body 1, thus meeting the user's need for functional modules that can be actively triggered by the smart ring 100.

[0026] In one embodiment, each assembly slot 12 has the same shape and size, and each housing 31 has the same shape and size.

[0027] All assembly slots 12 have the same shape and size, and all housings 31 have the same shape and size, allowing each housing 31 to be fitted into any assembly slot 12. This design improves the versatility between the functional modules 3 and the assembly slots 12, allowing different types of functional modules 3 to be selectively installed in any assembly slot 12. This further enhances the smart ring 100's ability to customize the functional modules 3, enabling users to freely combine the positions and types of functional modules 3 according to their needs, thus enhancing the smart ring 100's flexibility, adaptability, and expandability. Simultaneously, the unified structural design facilitates mass production and assembly, reducing manufacturing costs and structural complexity.

[0028] Please combine Figure 5 and Figure 10In one embodiment, each functional module 3 includes a housing 31 and a functional component 32 assembled within the housing 31. Each housing 31 is shaped to match at least one assembly slot 12 and can be inserted into the assembly slot 12. Each functional component 32 can communicate with the flexible circuit board 21 when the housing 31 is inserted into the assembly slot 12 that matches its shape. The functional component 32 includes an active functional component 32, a passive functional component 32, and a triggering functional component 32. The passive functional component 32 is used to operate when the housing 31 is inserted into the assembly slot 12 that matches its shape and to send a transmission signal to the flexible circuit board 21. The active functional component 32 is used to operate when it receives an instruction. The triggering functional component 32 is used to send a trigger signal to the flexible circuit board 21 when it is triggered.

[0029] It should be noted that the active functional component 32 can be a camera device, speaker device, microphone device, infrared transmitter device, or other device that can actively operate after receiving a command. When the active functional component 32 is an output device, such as a speaker device or infrared transmitter device, it outputs data after receiving a command. When the active functional component 32 is a receiving device, such as a camera device or microphone device, it collects data after receiving a command and sends it to the flexible circuit board 21, which can then transmit it to an external device. The trigger functional component 32 can be a joystick assembly, button assembly, switch assembly, trackball device, or other device that can be triggered to receive a command trigger signal. When the functional component 32 receives an instruction, the trigger signal formed by its input instruction is sent to the flexible circuit board 21, and can be sent to an external device through the flexible circuit board 21, thus achieving the effect of sending instructions outward through the trigger functional component 32. The passive functional component 32 can be a commonly used sensor module, such as an optical heart rate sensor (PPG), an electrical activity sensor (EDA), a temperature sensor, an accelerometer, a geomagnetic sensor, an NFC chip, a GPS chip, a barometer, an ambient light sensor, a gyroscope, etc., which do not require instructions but passively detect data and send transmission signals. The detected data is sent to the flexible circuit board 21, and can be sent to an external device through the flexible circuit board 21. By designing active functional components 32, passive functional components 32, and trigger functional components 32 with different functions and usage scenarios, the user's customization range is expanded, the applicable scenarios and functionality of the ring are increased, and the user experience is improved.

[0030] and, Figure 2 The active functional component 32 is a speaker device. Figure 3 The trigger function 32 in the middle is a switch component.

[0031] In one embodiment, the housing 31 includes an inner sidewall disposed near the inner wall of the ring body 1 and an outer sidewall disposed near the outer wall of the ring body 1. Active functional components 32 are disposed on the outer sidewall, and each active functional component 32 is one of a camera device, a speaker device, a microphone device, and an infrared emitting device. Trigger functional components 32 are disposed on the outer sidewall, and each trigger functional component 32 is one of a joystick assembly, a button assembly, a switch assembly, and a trackball device.

[0032] The active functional components 32 are disposed on the outer wall of the corresponding housing 31 corresponding to the ring 1, and each active functional component 32 is specifically defined as one of a camera device, a speaker device, a microphone device, and an infrared emitting device. This allows the active functional components 32 to be arranged in the most advantageous outer position for their operation without being restricted by the internal space of the ring 1. Since the active functional components 32 usually need to interact directly with the external environment, for example, the camera device needs an unobstructed shooting angle, the speaker device and the microphone device need a good sound channel, and the infrared emitting device needs an unobstructed emission direction, by disposing of the active functional components 32 on the outer wall of the corresponding housing 31 corresponding to the ring 1, the performance of the active functional components 32 can be fully utilized, avoiding the obstruction of effect due to installation inside the ring 1, thereby improving the overall working quality of the active functional components 32. The trigger function 32 is positioned on the outer wall of the corresponding ring 1 of its housing 31, and is limited to one of the following: a joystick assembly, a button assembly, a switch assembly, and a trackball device. This allows the user to operate the smart ring 100 directly through its outer surface without touching its internal structure, thereby improving ease of operation and response efficiency. Since the trigger function 32 requires direct force or contact from the user's hand, its placement on the outer surface of the smart ring 100 ensures a reasonable trigger position and intuitive operation.

[0033] In one embodiment, an antenna module (not shown) is also integrated on the touch circuit board 22; the passive functional component 32, the camera device, and the microphone device are used to transmit the collected data to the antenna module on the touch circuit board 22 via the flexible circuit board 21 and then send it to an external device; the joystick assembly, the button assembly, the switch assembly, and the trackball device are used to emit a trigger signal when triggered, and the trigger signal is transmitted to the antenna module on the touch circuit board 22 via the flexible circuit board 21 and then sent to an external device.

[0034] Since the flexible circuit board 21 and the touch circuit board 22 are arranged in a ring within the mounting cavity 11, a complete signal transmission link is formed between the antenna module, the flexible circuit board 21, and each functional component 32. Therefore, after the passive functional component 32, the camera device, and the microphone device collect data, they can directly transmit the data through the flexible circuit board 21 to the antenna module on the touch circuit board 22, and then send it to an external device through the antenna module. This allows the smart ring 100 to upload the collected data in real time, thereby enhancing the smart ring 100's data interaction capabilities. The trigger signals generated when the joystick assembly, button assembly, switch assembly, and trackball device are triggered can also be transmitted through the flexible circuit board 21 to the antenna module on the touch circuit board 22 and then sent to an external device. This allows the external device to receive the user's operation commands in real time, thereby realizing interactive control between the smart ring 100 and the external device.

[0035] Please combine Figure 4 and Figure 7 In one embodiment, the inner wall of the ring body 1 is provided with clearance holes 14 corresponding to the positions of each assembly slot 12, which are connected to the mounting cavity 11. The flexible circuit board 21 is provided with positioning holes 212 corresponding to each clearance hole 14, which are connected to the clearance holes 14. The passive functional component 32 is provided with sensor contacts 33 protruding from the housing 31 toward the inner wall of the ring body 1. When the housing 31 is inserted into the assembly slot 12 that matches its shape, the sensor contacts 33 pass through the positioning holes 212 and extend into the clearance holes 14.

[0036] After the functional module 3 is inserted into the assembly slot 12, the sensor contact 33 passes through the positioning hole 212 and extends into the clearance hole 14, allowing the sensor contact 33 to be directly exposed at the opening position of the inner wall of the ring body 1 and to make direct contact with the skin of the user when wearing the smart ring 100. By allowing the sensor contact 33 to directly contact the skin, the attenuation or obstruction of the sensor signal by the material of the ring body 1 can be significantly reduced, avoiding signal attenuation, delay or accuracy reduction caused by the thickness of the ring body 1, thereby improving the sensor's sensitivity and detection accuracy for physiological signals (such as temperature, heart rate, blood oxygen, skin electrical signals, etc.).

[0037] Please see Figure 4 In one embodiment, the circuit board assembly 2 further includes a battery 23, which is correspondingly disposed at the touch circuit board 22 and electrically connected to the touch circuit board 22. The battery 23 and the touch circuit board 22 are arranged radially along the ring 1.

[0038] In one embodiment, each functional module 3 is provided with a conductive contact 311, and the flexible circuit board 21 is provided with a connecting contact 211 at each assembly slot 12. When the functional module 3 is inserted into the assembly slot 12 that matches its shape, the conductive contact 311 is connected to the corresponding connecting contact 211 so that the functional module 3 is connected to the flexible circuit board 21.

[0039] When the functional module 3 is inserted into the assembly slot 12 that matches its shape, the conductive contact 311 can conduct with the corresponding connection contact 211, thereby achieving a reliable electrical connection between the functional module 3 and the flexible circuit board 21. This design ensures that the functional module 3 can achieve electrical conduction without additional soldering or complex connection operations during assembly, simplifying the assembly process of the smart ring 100. At the same time, it allows users to easily disassemble or replace the functional module 3 according to their personal needs, realizing the flexibility of customizing the functional module 3.

[0040] Please combine Figure 5 , Figure 6 , Figure 8 and Figure 9 In one embodiment, each assembly slot 12 is provided with a fixing frame 41. The inner end and outer end of the fixing frame 41 are respectively a hinge end 411 and a snap-fit ​​end 412 arranged radially along the ring body 1. The slot opening of the assembly slot 12 is arranged outward. Each functional module 3 has a snap-fit ​​hole 312 on one side corresponding to the snap-fit ​​end 412. The hinge end 411 is hinged to the bottom wall of the assembly slot 12. The snap-fit ​​end 412 can swing between the relaxed position and the snap-fit ​​position. When the functional module 3 is inserted into the assembly slot 12 through the slot opening, the snap-fit ​​end 412 can swing from the relaxed position toward the direction closer to the functional module 3 to the snap-fit ​​position so as to snap-fit ​​with the snap-fit ​​hole 312. The snap-fit ​​end 412 can also swing from the snap-fit ​​position to the relaxed position in the direction away from the functional module 3 so as to disengage from the snap-fit ​​hole 312.

[0041] When the functional module 3 is inserted into the assembly slot 12, the snap-fit ​​end 412 automatically swings from the relaxed position toward the snap-fit ​​position and engages with the snap-fit ​​hole 312, achieving an automatic locking effect. This eliminates the need for manual operation when inserting the functional module 3, improving assembly convenience. Simultaneously, the snap-fit ​​end 412 can also swing from the snap-fit ​​position away from the functional module 3 to the relaxed position, disengaging from the snap-fit ​​hole 312 and pushing the functional module 3 away from the assembly slot 12. This facilitates easy disassembly and replacement of the functional module 3. The conductive contact 311 is located on one side of the corresponding inner end of the functional module 3, ensuring that the snap-fit ​​engagement of the snap-fit ​​end 412 with the snap-fit ​​hole 312 does not interfere with the conduction between the functional module 3 and the conductive contact 311 of the connecting contact point 211, guaranteeing the stability of the electrical connection.

[0042] In one embodiment, the snap-fit ​​end 412 is provided with a snap-fit ​​block 4121 protruding toward the mounting groove 12 and a lever 4122 extending in a direction away from the mounting groove 12. The snap-fit ​​block 4121 is used to snap-fit ​​with the snap-fit ​​hole 312, and the lever 4122 is used to drive the snap-fit ​​end 412 from the snap-fit ​​position to the release position when it is pushed in a direction away from the mounting groove 12, so that the snap-fit ​​end 412 is disengaged from the snap-fit ​​hole 312, and the functional module 3 is pushed toward the groove opening through the hinge end 411 to push it away from the mounting groove 12.

[0043] The snap-fit ​​end 412 is provided with a snap-fit ​​block 4121 protruding towards the mounting groove 12 and a lever 4122 extending away from the mounting groove 12. The snap-fit ​​block 4121 is used to snap into the snap-fit ​​hole 312, so that the functional module 3 can be reliably locked after being inserted into the mounting groove 12, which further improves the positional stability of the functional module 3 during wearing and avoids the functional module 3 from loosening or falling off due to vibration, shaking or collision. In addition, the design of the lever 4122 makes the disassembly of the functional module 3 more convenient. The lever 4122 increases the force application area, making it easier for the user to push the lever 4122. The user only needs to push the lever 4122 away from the mounting groove 12 to automatically release the snap-fit ​​and partially push away the functional module 3, reducing the need for manual prying or forceful pulling and avoiding damage to the functional module 3 or the mounting groove 12.

[0044] In one embodiment, the hinge end 411 protrudes towards the assembly groove 12 to form an abutment block 4111. The functional module 3 is provided with an abutment groove 313 on one side of the inner wall of the ring body 1. When the functional module 3 is inserted into the assembly groove 12 that matches its shape, the abutment groove 313 abuts against the abutment block 4111 and drives the fixing frame 41 to rotate, so as to drive the locking end 412 to swing from the relaxed position to the locking position. The abutment block 4111 is also used to swing towards the opening of the assembly groove 12 when the paddle 4122 is pushed away from the assembly groove 12, so as to abut against the abutment groove 313 and push the functional module 3 towards the opening to push it away from the assembly groove 12.

[0045] The interaction between the abutment block 4111 and the abutment groove 313 enables the linkage between the insertion of the functional module 3 and the automatic locking action of the locking end 412. This allows the locking structure to fix the functional module 3 without additional manual intervention, improving the ease of insertion and ensuring reliable and stable locking action, thus enhancing the user experience during insertion. Furthermore, the linkage between the abutment block 4111 and the abutment groove 313 during disassembly provides an auxiliary pushing effect, allowing the functional module 3 to automatically disengage from the assembly groove 12 when the user pushes the lever 4122 away from the assembly groove 12. This reduces the force required for the user to directly pull the functional module 3, preventing wear or damage to the functional module 3 or the assembly groove 12 due to excessive force.

[0046] Understandably, the snap-fit ​​component 4 can be set on the side of the assembly groove 12 along the extension direction of the ring 1, or on the side of the assembly groove 12 along the axial direction of the ring 1, or both the side of the assembly groove 12 along the extension direction of the ring 1 and the side of the assembly groove 12 along the axial direction of the ring 1 can be provided with snap-fit ​​component 4. The number of snap-fit ​​components 4 is not limited and can be adjusted according to the size of the functional module 3 and the design requirements.

[0047] In one embodiment, the fixing frame 41 includes two swing arms 414 and a crossbeam 413 extending axially along the ring body 1. The two swing arms 414 are respectively disposed at both ends of the crossbeam 413 in the extending direction, and the swing arms 414 extend from the corresponding ends of the crossbeam 413 toward the inner wall of the ring body 1. The end of each swing arm 414 facing away from the crossbeam 413 forms a hinge end 411. The two hinge ends 411 are respectively hinged to the bottom wall of the mounting groove 12 on both sides along the axial direction of the ring body 1, and each hinge end 411 forms an abutment block 4111. The crossbeam 413 forms a locking end 412, and the locking block 4121 is disposed on the crossbeam 413 and located between the two swing arms 414. Specifically, the locking block is disposed at the middle of the crossbeam 413 in its extending direction.

[0048] Both ends of the crossbeam 413 are equipped with swing arms 414. When the fixed frame 41 is under force at the snap-fit ​​end 412, the force can be distributed to the hinge end 411 through the two swing arms 414, avoiding structural deformation or loose snap-fit ​​caused by unilateral force, and improving the overall strength and service life of the snap-fit ​​assembly 4. The hinge ends 411 of the two swing arms 414 each form abutment blocks 4111, so that when the functional module 3 is inserted into the assembly slot 12, the two abutment blocks 4111 can simultaneously abut against the abutment slot 313 on the functional module 3, and push the fixed frame 41 to rotate from two directions, so that the snap-fit ​​end 412 can swing stably from the relaxed position to the snap-fit ​​position, thereby improving the synchronicity and reliability of the snap-fit ​​action. Furthermore, the locking block 4121 is located in the middle of the crossbeam 413 along its extension direction, so that the limiting force applied by the locking block 4121 to the functional module 3 is also located in the middle of the functional module 3, avoiding uneven force on both sides causing the functional module 3 to tilt and causing the conducting contact 311 and the connecting contact 211 to separate, thus improving the stability of the connection of the functional module 3.

[0049] In one embodiment, each assembly slot 12 is provided with two snap-fit ​​components 4, which are respectively disposed on opposite sides of the assembly slot 12 along the circumference of the ring body 1.

[0050] The locking components 4 on opposite sides of the extension direction of the ring 1 can generate a more balanced locking force on the functional module 3, improving the overall fixing stability and preventing the functional module 3 from tilting, shaking, or partially disengaging due to unilateral force during wearing or movement of the smart ring 100. This improves the reliability of the functional module 3 within the assembly slot 12. Furthermore, compared to multiple locking components 4, two locking components 4, while ensuring stable fixing of the functional module 3, do not occupy excessive space in the assembly slot 12. The ring 1 also has more usable space in its extension direction, making it easier to install the locking components 4. Unlike locking components 4 located on opposite sides of the ring 1's axial direction, they do not occupy space in the width direction of the ring 1, allowing for a reduction in the size of the ring 1.

[0051] Please combine Figure 4 and Figure 5In one embodiment, each assembly slot 12 is provided with two first magnetic attractors 121 on opposite sides along the extension direction of the ring body 1, and each functional module 3 is provided with two second magnetic attractors 314 on opposite sides along the extension direction of the ring body 1. The two first magnetic attractors 121 are used to magnetically engage with the two second magnetic attractors 314 one by one after the functional module 3 is inserted into the assembly slot 12.

[0052] A stable magnetic force is formed between the functional module 3 and the assembly slot 12, ensuring that the functional module 3 maintains a precise position and stable state within the assembly slot 12. This prevents the functional module 3 from loosening, shifting, or falling off due to daily wear or external forces, thereby improving the assembly reliability and safety of the functional module 3. Simultaneously, the magnetic connection eliminates the need for additional mechanical locking components or complex operations during insertion or removal of the functional module 3, enabling convenient installation and disassembly. This further ensures the flexibility of customizing the smart ring 100's functional module 3, allowing users to easily replace the functional module 3 according to their needs.

[0053] Furthermore, please combine Figures 4 to 6 In one embodiment, the crossbeam 413 and the two swing arms 414 form a clearance space 415 extending along the axial direction of the ring body 1. Each assembly slot 12 is provided with two first magnetic suction members 121 on opposite sides of the ring body 1 along the circumference. The clearance space 415 of each first magnetic suction member 121 and the fixing member provided on the same side are correspondingly provided. Each functional module 3 is provided with two second magnetic suction members 314 on opposite sides of the circumference of the ring body 1. The two first magnetic suction members 121 are used to magnetically engage with the two second magnetic suction members 314 respectively after the functional module 3 is inserted into the assembly slot 12 that matches its shape.

[0054] Each first magnetic component 121 is positioned in a clearance space 415 corresponding to the fixing frame 41 on the same side, so that the first magnetic component 121 can be arranged in the assembly slot 12 without interfering with the swing path of the fixing frame 41 or affecting the action of the snap-fit ​​end 412, and the magnetic path will not be affected by the fixing frame 41, and the magnetic attraction effect will not be weakened due to the partition of the fixing component, so that the first magnetic component 121 and the second magnetic component 314 can be attracted more stably, thereby improving the stability of the functional module 3.

[0055] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
