Description

Technical Field

[0001] This utility model relates to the field of wearable electronic device technology, specifically a compact wearable electronic module and jewelry structure. Background Technology

[0002] Current smart wearable devices, such as smart rings and bracelets, generally adopt an integrated design, embedding electronic components firmly inside the jewelry's casing. However, the rigid connection between the electronic module and the jewelry body prevents users from changing jewelry parts to suit different usage scenarios or personal preferences. The traditional layout of the circuit board and battery severely limits the product's aesthetic design, making it difficult to meet consumers' pursuit of aesthetic value. Furthermore, because the electronic components of existing smart rings are tied to the ring size, different ring sizes require customized batteries and circuit boards, significantly increasing production and inventory costs. Traditional smart rings typically use a flexible circuit board integrated design for their NFC function modules, which not only limits signal strength but also necessitates maintaining a specific orientation during use, impacting the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a compact wearable electronic module and jewelry structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a compact wearable electronic module, comprising: a main electronic module, including a processor, a sensor group, and a communication module; a foldable structure, wherein the foldable structure is composed of a flexible circuit board, and the main electronic module occupies less space by folding; the main electronic module is provided with an electromagnetic shielding layer and a thermal insulation layer inside, for reducing electromagnetic interference and temperature interference caused by folding.

[0005] In one feasible implementation, the system further includes a battery sandwiched between folded flexible circuit boards, with the battery casing surface and the contact surface of the flexible circuit board forming a folded support surface. The battery is electrically connected to the main electronic module via a pad structure.

[0006] In one feasible implementation, the outer surface of the main electronic module is provided with a connection structure, which is a magnetic adsorption area or a mechanical snap-fit ​​groove, for the purpose of enabling detachable assembly.

[0007] An ornament structure includes an ornament shell, the interior of which is provided with an installation cavity; the installation cavity is provided with a corresponding connection structure that matches the connection structure of the main electronic module, the corresponding connection structure being a magnetic component or a snap-fit ​​component, for detachably assembling the main electronic module into the installation cavity of the ornament shell.

[0008] In one feasible implementation, the jewelry shell is a ring structure, including a ring setting and a ring band; the base of the ring setting is provided with a groove, and the connecting structure and a corresponding connecting structure are embedded in the edge of the groove.

[0009] In one feasible implementation, the ring is an openable metal structure for adjusting the finger circumference.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 6 This utility model provides a technical solution: a compact wearable electronic module, including: a main electronic module 2, comprising a processor, a sensor group, a communication module, and a foldable structure. The foldable structure is composed of a flexible circuit board 3, which compresses the three-dimensional space occupied by the main electronic module 2 through folding. The main electronic module 2 has an electromagnetic shielding layer and a thermal insulation layer inside to reduce electromagnetic interference and temperature interference caused by folding. This application achieves compactness and customizability of the electronic module while ensuring functional integrity through a modular and detachable structure and a three-dimensional folding design. The mounting cavity of the jewelry shell 1 provides space for modular assembly, allowing users to replace jewelry parts with different appearances according to their needs. The main electronic module 2 is detachable and assembled through a connection structure, solving the problem of non-replaceability caused by traditional rigid connections. The foldable structure uses a flexible circuit board 3, which compresses the occupied space through three-dimensional folding, breaking through the limitations of traditional circuit board layout on appearance design, while providing clamping space for components such as the battery 4. The electromagnetic shielding layer and thermal insulation layer added inside the main electronic module 2 respectively suppress electromagnetic signal interference caused by folding and heat conduction during the operation of electronic components, ensuring that the module still meets electromagnetic compatibility and thermal stability requirements in the folded state.

[0022] In some examples, this further includes a battery 4 sandwiched between folded flexible circuit boards 3, with the surface of the battery 4's outer shell and the contact surface of the flexible circuit board 3 forming a folding support surface. The battery 4 is electrically connected to the main electronic module 2 via a pad structure 5. By embedding the battery 4 into the sandwich of the folded flexible circuit board 3, and utilizing the physical properties of the contact surface between the battery 4's outer shell and the flexible circuit board 3 to form a folding support structure, space compression is achieved while maintaining the overall strength of the module. The bendable nature of the flexible circuit board 3 allows the battery 4 and the circuit board to form a three-dimensional stacked layout, breaking through the limitations of traditional planar layouts on the thickness of the jewelry. The electrical connection method of the pad structure 5 ensures circuit conduction and achieves modular separation of the battery 4 and the main electronic module 2, allowing batteries 4 of different sizes to be flexibly adapted and arranged in the jewelry according to finger size requirements. The folding support surface formed by the contact surface between the battery 4's outer shell and the flexible circuit board 3 replaces the independent support components in traditional designs, reducing the number of parts while avoiding structural deformation caused by folding operations.

[0023] In some examples, the outer surface of the main electronic module 2 is further provided with a connection structure, which is a magnetic adsorption area or a mechanical snap-fit ​​groove, for the purpose of enabling detachable assembly.

[0024] A jewelry structure includes a jewelry shell 1 with an internal mounting cavity. The mounting cavity contains a corresponding connection structure that matches the connection structure of a main electronic module 2. This corresponding connection structure is either a magnetic suction component or a snap-fit ​​component, used to detachably assemble the main electronic module 2 into the mounting cavity of the jewelry shell 1. The detachable assembly of the main electronic module 2 and the jewelry shell 1 is achieved through a physical connection via magnetic suction or snap-fit. The magnetic suction component utilizes the principle of magnetic adsorption to quickly complete a non-contact positioning connection between the main electronic module 2 and the mounting cavity while maintaining sufficient stability. The snap-fit ​​component achieves physical locking through a mechanical interlocking structure, ensuring that the module will not accidentally fall off during wear. A corresponding suction area or snap-fit ​​groove on the outer surface of the main electronic module 2 forms a matching snap-fit ​​with the connection structure inside the mounting cavity, ensuring positioning strength during assembly and disassembly while avoiding the complexity of rotation required by traditional threaded connections. This overcomes the limitations of the integrated structure of traditional smart jewelry, allowing users to freely replace jewelry shells 1 with different designs without affecting electronic functions.

[0025] In some examples, the jewelry shell 1 is further designed as a ring structure, including a ring setting 10 and a ring band 11. The base of the ring setting 10 has a groove, and the edge of the groove is fitted with connecting structures and corresponding connecting structures. By defining the jewelry shell 1 as a separate ring structure comprising the ring setting 10 and the ring band 11, and by providing a groove with connecting structures on the base of the ring setting 10, the electronic module and the ring band structure are decoupled. Specifically, the separate design of the ring setting 10 and the ring band 11 allows for independent adjustment of the ring size without altering the electronic module structure. The connecting structures embedded in the groove provide positioning for the electronic module, and the modular assembly method allows electronic modules of the same specification to be adapted to ring bands 11 of different sizes. This fundamentally solves the customization production problem caused by the integration of the electronic module and the ring band in traditional smart rings, while providing the universality of standardized electronic modules for users with different finger sizes.

[0026] In some examples, the ring band 11 is further designed as an openable metal structure for adjusting finger size. By designing the ring band 11 as an openable metal structure, the finger size can be freely adjusted. The openable structure allows users to manually adjust the opening angle of the ring band 11 through its mechanical deformation properties, directly changing the inner diameter of the ring band 11 to accommodate differences in finger circumference among different users. Using metal material ensures structural strength while leveraging the elastic deformation properties of metal to achieve repeatable adjustment, avoiding the mold development costs and inventory management pressures associated with traditional fixed ring bands 11 that require separate production for different finger sizes. This eliminates size fit issues for users while maintaining the overall rigidity of the jewelry.

[0027] In some examples, the ring 11 further includes a segmented NFC embedding area 111 and a base shell area 112. The NFC embedding area 111 is used to house the NFC coil module. The NFC coil module is electrically connected to the main electronic module 2 via another pad structure 5. The connection area between the main electronic module 2 and the NFC coil module is located within the base shell area 112. By dividing the ring 11 into functional zones, the independent and optimized assembly of the NFC module is achieved. Specifically, the segmented connection between the NFC embedding area 111 and the base shell area 112 ensures independent installation space for the NFC coil module and avoids signal interference through physical isolation. The NFC embedding area 111 is specifically designed to house the NFC coil module, allowing this functional module to be electromagnetically shielded independently, improving signal transmission stability. The connection to the main electronic module 2 via another pad structure 5 forms a modular circuit interface, simplifying the manufacturing process and enhancing maintainability. The connection area between the main module and the NFC module is located within the base shell area 112, utilizing the rigid structural characteristics of this area to ensure the reliability of the electrical connection while avoiding the impact of the connecting components on wearing comfort. This allows products with different finger sizes to be produced with only adjustments to the basic shell area 112, while the NFC function module can maintain standardized production, significantly reducing customization costs.

[0028] In some examples, the NFC embedding area 111 is further detachably connected to the base housing area 112 via a snap-fit ​​structure. The base housing area 112 has a through-hole groove 113, within which at least one of an electrode interface, a heart rate sensor, and a temperature sensor connected to the main electronic module 2 is disposed. The snap-fit ​​structure enables the detachable connection between the NFC embedding area 111 and the base housing area 112, allowing the NFC module and the main electronic module 2 to be maintained and replaced independently, while also ensuring the stability of signal transmission. The through-hole groove 113 in the base housing area 112 integrates the heart rate sensor or temperature sensor, utilizing the groove's penetrating properties to allow the sensor to directly contact the skin surface, improving detection accuracy while preventing sensor exposure from affecting the appearance of the jewelry. The electrode interface facilitates connection to an external charger, forming a power supply circuit for the battery 4. The snap-fit ​​structure and the through-hole groove 113 meet the flexible assembly requirements of the functional modules and optimize sensor layout space.
