Description

Technical Field

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

[0002] As a new type of wearable electronic device, a smart ring typically includes an outer ring, an inner ring, and a functional integrated module sealed between the two. To fit the ring's circular shape, the functional integrated module often uses a flexible printed circuit (FPC) as the mounting carrier, on which various electronic components such as batteries, information detection sensors, microprocessors, and wireless communication modules are arranged, thus forming a complete functional unit that can bend and fit the ring cavity.

[0003] In actual assembly, the aforementioned functional integration module needs to be placed entirely within the annular installation space defined between the outer and inner rings. However, due to the compact geometry of the smart ring, the available installation space inside is extremely limited. Directly placing the functional integration module, which uses a flexible circuit board as a carrier, into this narrow space is difficult due to the limited operating space, making it hard for assembly tools and the operator's fingers to apply force flexibly. This results in low assembly efficiency. Furthermore, the flexible circuit board is prone to uncontrollable deformation such as local bending, twisting, or warping during insertion or compression, causing the electronic components it carries, such as batteries and sensors, to deviate from their preset assembly positions.

[0004] Misalignment of components can cause not only short circuits, signal interference, or mechanical interference, but also affect the relative positioning accuracy between the sensor and the ring housing, ultimately reducing the yield and reliability of the smart ring. Summary of the Invention

[0005] The main objective of this invention is to provide a smart ring that reduces the assembly difficulty between the housing and the functional integration module.

[0006] To achieve the above objectives, the smart ring proposed in this invention includes: A housing, the housing comprising an outer ring and an inner ring; and An integrated module includes a functional integration module and a support member. The support member has multiple constraint edges, which enclose a constraint space. The functional integration module is disposed in the constraint space and connects to the surfaces of each constraint edge. The outer ring and the inner ring are respectively disposed on the outer and inner sides of the support member along the radial direction of the smart ring.

[0007] In one embodiment of the present invention, the support member includes an upper ring, a lower ring, and a constraint edge. The upper ring and the lower ring are correspondingly arranged along the axial direction of the smart ring, and each constraint edge extends along the axial direction of the smart ring. The two ends of each constraint edge are respectively connected to the upper ring and the lower ring. The outer ring is connected to the outer side of the upper ring and the lower ring along the radial direction of the smart ring, and the inner ring is connected to the inner side of the upper ring and the lower ring along the radial direction of the smart ring.

[0008] In one embodiment of the present invention, the outer ring extends a first length along the axial direction of the smart ring, and the inner ring extends a second length along the axial direction of the smart ring, wherein the first length is greater than the second length. Both the upper ring and the lower ring are bent and have a first connecting end face and a second connecting end face. The first connecting end face is further away from the radial center of the smart ring in the axial direction of the smart ring than the second connecting end face. The two ends of the outer ring are respectively connected to the first connecting end faces of the upper ring and the lower ring, and the two ends of the inner ring are respectively connected to the second connecting end faces of the upper ring and the lower ring.

[0009] In one embodiment of the present invention, the upper ring is provided with a first annular limiting groove, and the lower ring is provided with a second annular limiting groove. The first annular limiting groove and the second annular limiting groove are connected to form the constraint space.

[0010] In one embodiment of the present invention, each of the constraint edges is spaced apart along the circumferential direction of the smart ring.

[0011] In one embodiment of the present invention, both the outer ring and the inner ring are integrally formed structures.

[0012] In one embodiment of the present invention, the outer ring and the inner ring are manufactured by injection molding, so that the outer ring, the inner ring and the support member are integrally formed.

[0013] The present invention also proposes a ring assembly process for assembling a smart ring as described above, the ring assembly process comprising: The functional integration module is installed into the constraint space formed by the support member to form an integrated module; The outer ring and the inner ring are respectively installed on the outer and inner sides of the support member to obtain the smart ring.

[0014] The present invention also proposes a ring assembly process, the ring assembly process comprising: The functional integration module is installed into the constraint space formed by the support member to form an integrated module; The integrated module is injection molded so that the injection molding material forms an outer ring on the radially outer side and an inner ring on the radially inner side of the support, thereby forming the smart ring.

[0015] The present invention also proposes a ring kit comprising a smart ring as described in any of the above-described embodiments.

[0016] In this technical solution, the smart ring provided by the present invention adopts a structure in which the functional integration module is pre-connected to the constrained space of the support to form an integrated module, and the outer ring and inner ring are respectively set on the outer and inner sides of the support. This can effectively solve the problems of difficult assembly operation, easy deformation of flexible circuit board and deviation of electronic components from the preset position caused by directly stuffing the functional integration module of the flexible circuit board carrier into the narrow internal space of the ring. Specifically, during assembly, the functional integration module is first placed within the constrained space formed by the support component. Precise positioning and fixation of the module on the support component are achieved through surface connections with each constrained edge, ensuring a stable structural form and preventing uncontrollable bending or twisting of the flexible circuit board in a free state. Subsequently, the stabilized integrated module is treated as a single unit, with the outer and inner rings radially positioned on the outside and inside of the support component, respectively. At this point, only the fit accuracy between the outer and inner rings and the support component needs to be ensured, eliminating the need to directly adjust the position of the flexible circuit board or individual electronic components within a confined space. This significantly reduces assembly difficulty and improves assembly efficiency. Furthermore, since the functional integration module is connected to the support component before assembly, electronic components such as batteries and sensors can be precisely maintained in their designed positions. During subsequent assembly of the outer and inner rings, they will not shift due to compression or vibration, avoiding quality defects such as short circuits, signal interference, or sensor misalignment caused by component displacement. Ultimately, this significantly improves the yield and reliability of the smart ring. Attached Figure Description

[0024] To achieve the above objectives, please refer to Figure 1The smart ring 100 proposed in this invention includes: Housing 10, housing 10 includes an outer ring 11 and an inner ring 12; and The integrated module 20 includes a functional integration module 21 and a support member 22. The support member 22 has multiple constraint edges 223, which enclose a constraint space. The functional integration module 21 is located in the constraint space and connects to the surfaces of each constraint edge 223. The outer ring 11 and the inner ring 12 are respectively located on the outer and inner sides of the support member 22 along the radial direction of the smart ring 100.

[0025] Specifically, the housing 10 serves as the external structure of the smart ring 100, and its overall shape is circular to fit the human finger. The housing 10 includes an outer ring 11 and an inner ring 12. The outer ring 11 forms the outer peripheral surface of the smart ring 100, that is, the side away from the finger skin when worn, and mainly serves a decorative and protective function. The inner ring 12 forms the inner peripheral surface of the smart ring 100, that is, the side that contacts the finger skin when worn, and has skin-friendly and comfortable characteristics.

[0026] The outer ring 11 and the inner ring 12 can be two independent components, which are connected to the support 22 through subsequent assembly; or they can be a continuous structure integrally formed by injection molding or other processes, forming an annular space between them to accommodate the integrated module 20.

[0027] The materials of the outer ring 11 and the inner ring 12 can be selected according to functional requirements. The outer ring 11 can be made of metal (such as stainless steel, titanium alloy), ceramic or polymer materials (such as polycarbonate) to provide structural strength and appearance texture, while the inner ring 12 can be made of medical-grade plastic, silicone or flexible materials to improve wearing comfort.

[0028] The integrated module 20 is the core functional unit inside the smart ring 100, and its entirety is housed within the annular space between the outer ring 11 and the inner ring 12. The integrated module 20 includes a functional integration module 21 and a support component 22. The support component 22 is an intermediate structural component independent of the housing 10. Its material can be plastic (such as liquid crystal polymer, polyetheretherketone) or composite material, and it has a certain degree of rigidity, which can provide structural support for the functional integration module 21.

[0029] The support member 22 has multiple constraint edges 223, which are protruding structures on the support member 22 extending toward the functional integration module 21. Their shape can be plate-like, column-like, or rib-like, and is not limited here. The multiple constraint edges 223 are distributed circumferentially or around the support member 22, and together they enclose a constraint space. The outer contour of this constraint space matches the outer contour of the functional integration module 21, and the area of ​​the constraint space is used to accommodate the functional integration module 21.

[0030] In some embodiments, the number of constraint edges 223 is at least two, preferably three or more, in order to limit the functional integration module 21 from multiple directions. Therefore, the number of constraint edges 223 is not limited.

[0031] The extension direction of the constraint edge 223 is consistent with the axial direction of the smart ring 100, so that the constraint space is also along the axial direction of the smart ring 100, thereby adapting to the shape of the smart ring 100. The constraint space can be a continuous area jointly defined by the inner surface of the constraint edge 223 or a continuous area jointly defined by the outer surface of the constraint edge 223. That is, the functional integration module 21 can be sleeved on the outside of the support member 22 or disposed inside the support member 22, which is not limited here.

[0032] The functional integration module 21 is an assembly that uses a flexible circuit board as its mounting carrier and integrates electronic components such as a battery, information detection sensor, microprocessor, and wireless communication module on the flexible circuit board. The flexible circuit board has the characteristic of being flexible, allowing it to adapt to the annular contour of the smart ring 100. The functional integration module 21 is disposed in the constrained space formed by the support member 22 and is connected to the surface of each constraining edge 223. The connection between the functional integration module 21 and each constraining edge 223 can be a direct connection, such as temporary fixation through an interference fit between the constraining edge 223 and the functional integration module 21, or permanent bonding of the two through an adhesive layer; or it can be an indirect connection, such as wrapping and fixing the functional integration module 21 and the constraining edge 223 together through an injection-molded covering layer. Regardless of the connection method used, the purpose is to ensure that the functional integration module 21 is accurately positioned on the support member 22, and that the two are combined to form a stable and non-deformable integral unit. Because the enclosure structure of the constraint edge 223 limits the functional integration module 21 from multiple directions, the flexible circuit board can maintain its preset bending shape after connection and will not bend, twist or warp freely in subsequent operations.

[0033] When the functional integration module 21 and the support member 22 are combined into one unit in the above manner, an integrated module 20 is formed. This integrated module 20, as a complete pre-assembly unit, is positioned between the outer ring 11 and the inner ring 12. Specifically, the outer ring 11 is positioned on the outside of the support member 22 along the radial direction of the smart ring 100, and the inner ring 12 is positioned on the inside of the support member 22 along the radial direction of the smart ring 100. The outer ring 11 and the support member 22, and the inner ring 12 and the support member 22, can be connected in various ways, such as snap-fit, interference fit, bonding, ultrasonic welding, or injection molding, etc., without limitation. Based on this, the outer ring 11 and the inner ring 12 can be independently connected to the support member 22, or they can be formed simultaneously and wrap the outer and inner sides of the support member 22 through a single injection molding process.

[0034] Regardless of the assembly method used, the core is that the integrated module 20 is held or wrapped by the outer ring 11 and the inner ring 12 from both radially inner and outer sides as a whole unit, thus forming a complete smart ring 100 structure.

[0035] In this technical solution, the smart ring 100 provided by the present invention adopts a structure in which the functional integration module 21 is pre-connected to the constrained space of the support member 22 to form an integrated module 20, and the outer ring 11 and inner ring 12 are respectively set on the outer side and the inner side of the support member 22. This can effectively solve the problems of difficult assembly operation, easy deformation of flexible circuit board and deviation of electronic components from the preset position caused by directly stuffing the functional integration module 21 of the flexible circuit board carrier into the narrow internal space of the ring. Specifically, during assembly, the functional integration module 21 is first placed within the constrained space enclosed by the support member 22. Precise positioning and fixation of the functional integration module 21 on the support member 22 are achieved through surface connections with each constraining edge 223, ensuring a stable structural form for the functional integration module 21 and preventing uncontrollable bending or twisting of the flexible circuit board in a free state. Subsequently, the integrated module 20, with its stable structure formed, is treated as a single unit. The outer ring 11 and inner ring 12 are respectively positioned radially on the outer and inner sides of the support member 22. At this point, only the fitting accuracy between the outer ring 11, inner ring 12, and support member 22 needs to be ensured; there is no need to directly adjust the position of the flexible circuit board or individual electronic components within a confined space, thus significantly reducing assembly difficulty and improving assembly efficiency. Simultaneously, since the functional integration module 21 is connected to the support member 22 before assembly, electronic components such as batteries and sensors on it can be precisely maintained in their designed positions. During the subsequent assembly of the outer ring 11 and inner ring 12, they will not shift due to compression or vibration, avoiding quality defects such as short circuits, signal interference, or sensor misalignment caused by component shifting.

[0036] Through the above structure, the present invention transfers the complex positioning operation that originally needed to be completed in the narrow space inside the ring to be completed in advance outside the shell 10. After the functional integration module 21 is positioned in the constrained space and connected to the constrained edge 223, it forms a stable and easy-to-operate integrated module 20 together with the support member 22. Assembly can be completed simply by setting the outer ring 11 and the inner ring 12 on the outside and inside of the integrated module 20, respectively. This significantly reduces the assembly difficulty and improves the yield of finished products, while achieving efficient and reliable production and manufacturing.

[0037] In one embodiment of the present invention, please refer to Figure 2The support member 22 includes an upper ring 221, a lower ring 222, and constraint edges 223. The upper ring 221 and the lower ring 222 are correspondingly arranged along the axial direction of the smart ring 100. Each constraint edge 223 extends along the axial direction of the smart ring 100, and the two ends of each constraint edge 223 are respectively connected to the upper ring 221 and the lower ring 222. The outer ring 11 is connected to the outer side of the upper ring 221 and the lower ring 222 along the radial direction of the smart ring 100, and the inner ring 12 is connected to the inner side of the upper ring 221 and the lower ring 222 along the radial direction of the smart ring 100.

[0038] In this embodiment, both the upper ring 221 and the lower ring 222 are annular components. The upper ring 221 and the lower ring 222 are positioned opposite each other and spaced apart along the axial direction of the smart ring 100 (i.e., the direction in which the finger is inserted or pulled out), thereby forming the two end structures of the smart ring 100.

[0039] The upper ring 221 and lower ring 222 can be made of plastic (such as liquid crystal polymer, polyetheretherketone) or composite materials, possessing high rigidity and dimensional stability, and are used to provide structural boundaries for the entire support member 22 at both axial ends. The constraint edges 223 extend along the axial direction of the smart ring 100, with their ends fixedly connected to the upper ring 221 and lower ring 222 respectively, thus connecting the upper ring 221 and lower ring 222 into a whole. Multiple constraint edges 223 are distributed circumferentially along the smart ring 100, forming a cage-like structure together with the upper ring 221 and lower ring 222. The interior of this cage-like structure forms a receiving area extending along the axial direction of the smart ring 100, and its overall shape is roughly cylindrical or lantern-shaped. Because the upper ring 221 and lower ring 222 connect and fix multiple constraint edges 223 from both ends, the entire support member 22 has extremely high structural rigidity in the axial, radial, and circumferential directions. Even under external force, there will be no relative displacement or deformation between the constraint edges 223.

[0040] The outer ring 11 is connected to the outer side of the upper ring 221 and the lower ring 222 along the radial direction of the smart ring 100. That is, the inner circumferential surface of the outer ring 11 is opposite to and in contact with the outer circumferential surface of the upper ring 221 and the outer circumferential surface of the lower ring 222. It can be fixedly connected by means of adhesive, snap, interference fit or ultrasonic welding.

[0041] Similarly, the inner ring 12 is connected to the inner side of the upper ring 221 and the lower ring 222 along the radial direction of the smart ring 100. That is, the outer circumferential surface of the inner ring 12 is opposite to and in contact with the inner circumferential surface of the upper ring 221 and the inner circumferential surface of the lower ring 222, and can also be fixedly connected in a corresponding manner. The upper ring 221 and the lower ring 222 act as a connecting bridge, enabling the outer ring 11 and the inner ring 12 to be precisely aligned and firmly connected with the support member 22 from the radially outer side and the radially inner side, respectively.

[0042] Based on the above, the cage-like support structure formed by the upper ring 221, lower ring 222, and constraint edge 223 provides all-round rigid support for the functional integration module 21. After the functional integration module 21 is fitted onto the outside or inside of the constraint edge 223, its shape is forced to maintain the designed posture, and the flexible circuit board cannot be freely bent or twisted, which significantly improves the overall structural rigidity of the integrated module 20. Secondly, the upper ring 221 and lower ring 222, as independent ring components, provide a clear ring connection interface for the outer ring 11 and the inner ring 12. This structure ensures that the outer ring 11 and inner ring 12 are precisely aligned and firmly connected, avoiding potential positional deviations or insufficient connection strength caused by direct connection with the constraint edge 223. Finally, this structure clearly separates the connection interfaces between the outer ring 11, inner ring 12 and support member 22, allowing the outer ring 11 and inner ring 12 to be manufactured separately using different materials and processes (e.g., wear-resistant metal for the outer ring 11 and skin-friendly soft rubber for the inner ring 12) before assembly. This satisfies the differentiated needs for appearance and wearing comfort while reducing overall manufacturing costs.

[0043] In one embodiment of the present invention, please refer to Figure 1 and Figure 3 The outer ring 11 extends a first length along the axial direction of the smart ring 100, and the inner ring 12 extends a second length along the axial direction of the smart ring 100, with the first length being greater than the second length. The upper ring 221 and the lower ring 222 are both bent and have a first connecting end face 22a and a second connecting end face 22b. The first connecting end face 22a is farther away from the radial center of the smart ring 100 along the axial direction of the smart ring 100 than the second connecting end face 22b. The two ends of the outer ring 11 are respectively connected to the first connecting end face 22a of the upper ring 221 and the lower ring 222, and the two ends of the inner ring 12 are respectively connected to the second connecting end face 22b of the upper ring 221 and the lower ring 222.

[0044] In this embodiment, the outer ring 11 extends a first length along the axial direction of the smart ring 100, which is greater than the second length of the inner ring 12 extending in the same direction. This length difference allows the outer ring 11 to cover a wider area axially, while the inner ring 12 is relatively shorter, exposing part of the inner structure of the support member 22. The materials of the outer ring 11 and the inner ring 12 can be selected according to functional requirements. The outer ring 11 can be made of metal or hard plastic to provide structural protection and decorative appearance, while the inner ring 12 can be made of skin-friendly soft rubber or medical-grade plastic to improve wearing comfort.

[0045] Both the upper ring 221 and the lower ring 222 employ a bent structure, thereby forming two first connecting end faces 22a and 22b at different axial positions. Specifically, the first connecting end face 22a is further away from the radial center of the smart ring 100 along the axial direction than the second connecting end face 22b. The "radial center" refers to the center of the central axis of the smart ring 100, meaning the first connecting end face 22a is located at the end of the ring, while the second connecting end face 22b is located inward from the end of the ring. Through this bent design, the upper ring 221 and the lower ring 222 form a stepped connection interface in the axial direction, with the first connecting end face 22a located radially outward and axially outward, and the second connecting end face 22b located radially inward and axially inward.

[0046] Since the first connecting end face 22a is located on the outer side of the axis, the outer ring 11 can cover the entire radial outer side of the support member 22 and part of the axial end area after connection, forming a relatively complete outer peripheral protective layer; since the second connecting end face 22b is located on the inner side of the axis, the inner ring 12 is accommodated in the space enclosed by the outer ring 11 after connection, and its two axial ends are recessed inward relative to the ends of the outer ring 11, forming a stepped appearance profile.

[0047] In this invention, the design of the outer ring 11 being longer than the inner ring 12 allows the outer ring 11 to completely wrap around the upper ring 221, lower ring 222, and constraint edge 223 of the support member 22 from the outside, forming a continuous and complete outer circumferential surface, which improves the overall aesthetics and structural protection of the smart ring 100. The relatively short inner ring 12 design ensures that the inner ring 12 only contacts a part of the finger when worn, which not only ensures the necessary friction to prevent the ring from slipping off, but also avoids the pressure or discomfort that may be caused by an excessively long inner ring 12.

[0048] Furthermore, the upper ring 221 is provided with a first annular limiting groove, and the lower ring 222 is provided with a second annular limiting groove. The first annular limiting groove and the second annular limiting groove are connected to form a constraint space.

[0049] In this embodiment, the upper ring 221 serves as one axial end structure of the support member 22, and a first annular limiting groove is provided on the side facing the constraint edge 223. The first annular limiting groove is an annular groove that extends continuously along the circumferential direction of the smart ring 100, and its opening direction is towards the constraint space. Similarly, the lower ring 222 serves as the other axial end structure of the support member 22, and a second annular limiting groove is provided on the side facing the constraint edge 223. The second annular limiting groove is an annular groove that extends continuously along the circumferential direction of the smart ring 100, and its opening direction is towards the constraint space.

[0050] The first and second annular limiting grooves are arranged opposite each other in the axial direction and are interconnected through the internal space of the support member 22, thereby forming an annular cavity extending in the axial direction. This annular cavity is the constraint space for accommodating the functional integration module 21. The cross-sectional shape of the first and second annular limiting grooves can be rectangular, trapezoidal, arc-shaped, or V-shaped, and their specific shapes can be adapted to the contour of the end of the functional integration module 21.

[0051] In one embodiment, the first annular limiting groove and the second annular limiting groove are located on the outer side of the upper ring 221 and the lower ring 222, respectively. At this time, the constraint space is formed on the outer surface of the support member 22. During assembly, the functional integration module 21 is sleeved on the outer surface of the support member 22.

[0052] In another embodiment, the first annular limiting groove and the second annular limiting groove are located inside the upper ring 221 and the lower ring 222, respectively. In this case, the constraint space is formed on the inner surface of the support member 22. During assembly, the functional integration module 21 is located inside the support member 22.

[0053] During actual assembly, the two ends of the functional integration module 21 are respectively embedded in the first annular limiting groove and the second annular limiting groove, so that the functional integration module 21 can be accurately positioned in the axial direction. At the same time, the sidewall of the limiting groove can also restrict the movement of the functional integration module 21 in the radial direction.

[0054] Thus, the annular limiting grooves on the upper ring 221 and lower ring 222 provide a clear and continuous positioning reference for both ends of the functional integration module 21 along its axial direction, ensuring that the axial position of the functional integration module 21 within the support 22 is precisely locked, avoiding sensor alignment deviations or poor circuit contact caused by inaccurate axial positioning. Secondly, the continuous structure of the annular limiting grooves provides uniform support and constraint to the ends of the functional integration module 21 in the circumferential direction. Compared to end positioning using only discrete constraint edges 223, the limiting grooves provide a larger contact area and a more stable holding force, effectively preventing the functional integration module 21 from shifting or warping in the axial direction. Thirdly, the limiting grooves and constraint edges 223 work together to form a multi-dimensional constraint system of "axial limiting + circumferential limiting + radial limiting," completely fixing the functional integration module 21 within the support 22. Even without the use of adhesives or injection molding materials, it maintains a stable posture, greatly facilitating the subsequent assembly of the outer ring 11 and inner ring 12. Finally, the structural design of the annular limiting groove simplifies the assembly operation of the functional integration module 21. The operator only needs to push the two ends of the functional integration module 21 into the first annular limiting groove and the second annular limiting groove respectively to quickly complete the initial positioning without complicated alignment procedures, which significantly improves assembly efficiency and is especially suitable for batch operations on automated production lines.

[0055] In one embodiment of the present invention, please refer to Figure 2 Each constraint edge 223 is spaced apart along the circumferential direction of the smart ring 100.

[0056] In this embodiment, the number of constraint edges 223 can be selected according to the size and functional requirements of the support member 22, typically three, four or more, to achieve structural optimization while ensuring sufficient constraint force. The cross-sectional shape of the constraint edge 223 can be rectangular, trapezoidal, arc-shaped or other geometric shapes, and its circumferential width can be set according to the structural strength requirements.

[0057] Any two adjacent constraint edges 223 are spaced apart along the circumferential direction of the smart ring 100, forming through gaps, giving the support member 22 an overall cage-like or fence-like appearance. This spaced arrangement makes the through gaps between adjacent constraint edges 223 open areas on the support member 22. These through gaps are evenly distributed along the circumference of the smart ring 100, connecting the radially inner space and the radially outer space of the support member 22.

[0058] When the functional integration module 21 is fitted inside or outside the constraint edge 223, these through-holes remain open, forming a channel connecting the inner and outer sides of the support member 22. The size of the through-holes can be adjusted according to actual needs; they can be designed as narrow gaps for fluid or medium passage only, or as wide openings to facilitate the insertion or observation of assembly tools.

[0059] In this embodiment, firstly, the spacing of the constraint edges 223 significantly reduces the overall weight of the support 22. For wearable devices like the smart ring 100, which require high wearing comfort, the weight reduction directly improves the user's wearing experience and reduces the burden during prolonged wear. Secondly, the through gaps formed between the spaced constraint edges 223 can serve as channels for the flow of injection molding material during subsequent injection molding sealing or potting processes. This allows the sealing medium to flow freely between the radially inner and radially outer sides of the support 22, enabling the filling of all gaps in a single injection without the need for multiple injection ports or multiple injection molding processes, simplifying the production process and improving production efficiency. Finally, the spacing of the constraint edges 223 also reduces the contact area between the support 22 and the functional integration module 21. When bonding or encapsulation is required for fixation, this saves on the amount of fixing medium used and provides more space and pathways for the filling and curing of the fixing medium, which is conducive to forming a more uniform and reliable fixing effect.

[0060] In one embodiment of the present invention, both the outer ring 11 and the inner ring 12 are integrally formed structures.

[0061] In this embodiment, the outer ring 11 and the inner ring 12 are two independent components, each manufactured using an integral molding process. The outer ring 11 is a complete annular component with an overall ring shape, used to form the outer peripheral surface and part of the end face contour of the smart ring 100. The integral molding of the outer ring 11 can be achieved by metal injection molding, precision casting, CNC machining, or injection molding. Its material can be selected according to design requirements, such as metal (e.g., stainless steel, titanium alloy), ceramic, or polymer materials (e.g., polycarbonate, polyamide). Since the outer ring 11 is integrally molded, its structure is continuous and seamless, with a smooth and flat surface, presenting a good appearance and structural integrity.

[0062] The inner ring 12 is also a complete ring component, with an overall circular shape, used to form the inner circumference of the smart ring 100, that is, the part that directly contacts the skin of the finger. The one-piece molding of the inner ring 12 can be achieved by injection molding or compression molding, and its material is usually selected from skin-friendly materials such as medical-grade plastic, thermoplastic elastomer, or silicone to ensure comfort and safety when wearing it.

[0063] After manufacturing, the outer ring 11 and inner ring 12 are stored and prepared as independent components, and will be assembled with the integrated module 20 during subsequent assembly. At the same time, as two independent components, the outer ring 11 and inner ring 12 are completely decoupled in terms of material selection. The outer ring 11 can be made of hard material to provide structural protection and decorative effect, while the inner ring 12 can be made of soft material to improve wearing comfort. The two do not restrict each other.

[0064] During assembly, the functional integration module 21 is first combined with the support component 22 to form an integrated module 20. Then, the integrally formed outer ring 11 and inner ring 12 are respectively installed on the outer and inner sides of the integrated module 20. The outer ring 11 is fixedly connected to the outer surface of the support component 22 (i.e., the outer circumferential surfaces of the upper ring 221 and lower ring 222) through methods such as bonding, snap-fitting, interference fit, or ultrasonic welding; the inner ring 12 is similarly fixedly connected to the inner surface of the support component 22 (i.e., the inner circumferential surfaces of the upper ring 221 and lower ring 222) through the same method. After the outer ring 11 and inner ring 12 are connected to the support component 22, the three together constitute the complete structure of the smart ring 100.

[0065] Based on this, the outer ring 11 and inner ring 12 each adopt a one-piece molding structure, allowing for independent selection and optimization of their materials, colors, and surface treatment processes. The outer ring 11 can prioritize high hardness, wear resistance, and a metallic texture, while the inner ring 12 can prioritize softness, skin-friendliness, and biocompatibility. This ensures product reliability while simultaneously meeting the dual requirements of aesthetic appeal and wearing comfort. Furthermore, as independent components, the outer ring 11 and inner ring 12 can be mass-produced and quality-controlled separately, reducing the manufacturing cost of individual components, improving overall production efficiency, and facilitating inventory management and supply chain coordination. Finally, this modular structure gives the smart ring 100 excellent repairability and customizability. When the outer ring 11 or inner ring 12 shows wear or scratches, or when the user wishes to change the appearance to a different color or material, only the corresponding component needs to be replaced, without scrapping the entire ring. This extends the product's lifespan and meets the user's personalized needs.

[0066] In one embodiment of the present invention, the outer ring 11 and the inner ring 12 are manufactured by injection molding, so that the outer ring 11, the inner ring 12 and the support member 22 are integrally formed.

[0067] In this embodiment, the outer ring 11 and the inner ring 12 are integrated with the support member 22 through an injection molding process. Specifically, the support member 22 (i.e., the integrated module 20) that has completed the assembly of the functional integration module 21 is first placed as an insert into the cavity of the injection mold. The cavity of the mold is designed to accommodate the integrated module 20, and a space is reserved on its radially outer side for forming the outer ring 11 and a space is reserved on its radially inner side for forming the inner ring 12.

[0068] After the mold is closed, molten thermoplastic (such as polycarbonate, polyamide, thermoplastic polyurethane or liquid crystal polymer) is injected into the mold cavity through an injection molding machine. The injection material flows under pressure and fills the space on the radially outer side and the radially inner side of the integrated module 20 respectively, and at the same time makes close contact with the outer surface and the inner surface of the support 22.

[0069] After the injection molding material cools and solidifies, an outer ring 11 is formed on the radially outer side of the support 22 and an inner ring 12 is formed on the radially inner side. The outer ring 11 and the inner ring 12 are connected to the support 22 by melting and bonding during the injection molding process to form a strong integrated connection.

[0070] The outer ring 11 and inner ring 12 can be made of the same injection molding material, or different materials can be selected using two-color injection molding or two-stage injection molding processes to meet the differentiated needs of appearance, texture, and wearing comfort. For example, the outer ring 11 can be made of polycarbonate with high hardness to provide wear resistance and gloss, while the inner ring 12 can be made of soft thermoplastic elastomer to improve wearing comfort. After injection molding, the product is removed from the mold, resulting in a semi-finished or finished smart ring 100 with the outer ring 11, inner ring 12, and support component 22 integrally formed. Subsequently, the functional integration module 21 can be further installed or subsequent processing can be performed as needed.

[0071] In this invention, the outer ring 11 and inner ring 12 are simultaneously formed through injection molding, and both are firmly integrated with the support component 22. This eliminates the need for separate manufacturing of the outer ring 11 and inner ring 12, as well as subsequent assembly processes, significantly simplifying the production process and improving manufacturing efficiency, making it particularly suitable for mass automated production. Secondly, the injection-molded outer ring 11 and inner ring 12 achieve a seamless connection with the support component 22, eliminating the gaps or relative movement that may occur in separate assembly methods. This greatly enhances the overall structural strength and impact resistance of the smart ring 100, while also eliminating any abnormal noises or looseness that may result from gaps. Thirdly, the one-piece molding structure ensures the relative positional accuracy between the outer ring 11 and inner ring 12 directly through mold precision, eliminating the need for additional alignment adjustments during assembly and effectively preventing appearance defects or functional abnormalities caused by assembly deviations. Furthermore, during the curing process, the injection molding material can fill the through gaps formed by the spaced constraint edges 223 on the support member 22, so that the outer ring 11 and the inner ring 12 are connected to each other at these gaps to form a whole, thereby forming a "riveted" anchoring structure between the inner and outer sides of the support member 22, which further enhances the bonding strength between the outer ring 11, the inner ring 12 and the support member 22, and will not delaminate or detach even after long-term use or when subjected to external impact.

[0072] This invention also proposes a ring assembly process for assembling the smart ring 100 as described above. Please refer to [link to relevant documentation]. Figure 4 The ring assembly process includes: S10: The functional integration module 21 is installed into the constrained space formed by the support member 22 to form the integrated module 20; S20: Install the outer ring 11 and the inner ring 12 on the outer and inner sides of the support member 22 respectively to obtain the smart ring 100.

[0073] In step 10, the operator first obtains the support member 22, which has multiple constraint edges 223, and the constraint edges 223 together enclose a constraint space. The support member 22 can be made of plastic (such as liquid crystal polymer, polyetheretherketone) or composite material, has a certain rigidity, and its overall shape is a cage-like or fence-like structure, used to provide structural support for the functional integration module 21.

[0074] Meanwhile, the operator acquires the functional integration module 21, which is a component that uses a flexible circuit board as the mounting carrier and integrates electronic components such as batteries, information detection sensors, microprocessors, and wireless communication modules.

[0075] Because flexible circuit boards are bendable, their shape is unstable in a free state. The operator manually or using an automated fixture aligns the functional integration module 21 with the opening of the constraint space and then places it into the constraint space.

[0076] During the placement process, the surface of the constraint edge 223 will contact or be close to the outer edge of the functional integration module 21, guiding and limiting the circumferential and radial positions of the module, so that the functional integration module 21 naturally falls into the preset axial and radial positions.

[0077] The functional integration module 21 and the constraint edge 223 can be a clearance fit, a transition fit, or a slight interference fit to form a preliminary temporary fixation.

[0078] After the functional integration module 21 is placed into the support member 22, the functional integration module 21 is constrained from multiple directions by the constraint edge 223, preventing it from undergoing significant displacement, rotation, or warping during subsequent handling or assembly. This forms an integrated module 20 composed of the support member 22 and the functional integration module 21. Essentially, this step transfers the complex positioning operations that would normally be performed in the confined space inside the housing 10 to a spacious, open environment outside the housing 10, avoiding the deformation risks associated with directly manipulating the flexible circuit board in a limited space. Simultaneously, the support member 22 strengthens the structural form of the functional integration module 21, preventing deformation.

[0079] In step 20, the operator obtains the pre-assembled integrated module 20 and the independently manufactured outer ring 11 and inner ring 12, wherein the outer ring 11 and inner ring 12 are both annular components, the outer ring 11 is used to form the outer peripheral surface of the smart ring 100, and the inner ring 12 is used to form the inner peripheral surface of the smart ring 100.

[0080] The outer ring 11 and the inner ring 12 can be pre-made as a single piece through injection molding, casting or machining. The material can be selected according to functional requirements. The outer ring 11 can be made of metal or hard plastic to provide structural protection and decoration, while the inner ring 12 can be made of skin-friendly soft rubber or medical-grade plastic to improve wearing comfort.

[0081] The operator manually or using an automated clamp grips the support component 22 of the integrated module 20. First, the outer ring 11 is fitted onto the outside of the support component 22 along the radial direction of the smart ring 100, so that the inner circumferential surface of the outer ring 11 is opposite to and in contact with the outer surface of the support component 22. The outer ring 11 is fixedly connected to the support component 22 by means of bonding, snap-fit, interference fit or ultrasonic welding.

[0082] Subsequently, the inner ring 12 is positioned on the inner side of the support member 22 along the radial direction of the smart ring 100, so that the outer peripheral surface of the inner ring 12 is opposite to and in contact with the inner surface of the support member 22, and the inner ring 12 is fixedly connected to the support member 22 in the same manner.

[0083] The installation order of the outer ring 11 and the inner ring 12 can be adjusted according to the specific structural design. The outer ring 11 can be installed first, followed by the inner ring 12, or vice versa, or they can be installed simultaneously. Since the functional integration module 21 is reliably positioned by the constraint edge 223 in step S10, its overall shape is stable and not easily deformed. Therefore, no further adjustments to the flexible circuit board or any electronic components are required during the installation of the outer ring 11 and the inner ring 12. After the outer ring 11 and the inner ring 12 are connected to the support member 22, the three together constitute the complete structure of the smart ring 100, with the functional integration module 21 securely encapsulated between the outer ring 11 and the inner ring 12.

[0084] In some embodiments, after the functional integration module 21 is installed into the constraint space of the support member 22, the two can be integrally encapsulated using an injection molding process. This involves placing the pre-assembled semi-finished product into an injection mold, injecting molten thermoplastic (such as polyamide, thermoplastic polyurethane, or liquid crystal polymer), filling the gap between the constraint edge 223 and the functional integration module 21 with the injection molding material, and forming a covering layer after cooling and solidification. This covering layer firmly bonds the functional integration module 21 and the constraint edge 223 together, forming an inseparable, morphologically stable integrated module 20. After injection molding and curing, the position of the functional integration module 21 in the support member 22 is locked, and its flexible circuit board is completely encapsulated and protected by the injection molding material. Even if subjected to large assembly forces or vibrations during the subsequent installation of the outer ring 11 and inner ring 12, no displacement or deformation will occur, further improving the reliability of the assembly and the durability of the product.

[0085] In other embodiments, after the functional integration module 21 is installed into the constraint space of the support member 22, before installing the outer ring 11 and inner ring 12 on the outer and inner sides of the support member 22, a tooling can be used to fix the functional integration module 21 in the integrated module 20 relative to the support member 22. This tooling can apply clamping or positioning forces from the outside, so that the functional integration module 21 maintains a stable posture in the constraint space enclosed by the constraint edge 223, preventing relative movement due to operating forces during the subsequent installation of the outer ring 11 and inner ring 12. The tooling can be removed after the outer ring 11 and inner ring 12 are installed in place, or after the outer ring 11 and inner ring 12 are initially fixed to the support member 22. With the assistance of the tooling, even if the integrated module 20 only uses a temporary fixing method (such as clearance fit) in step S10, it can maintain a high-precision relative position in step S20, ensuring the alignment accuracy of the outer ring 11 and inner ring 12 during installation, thereby further improving the assembly yield and product consistency.

[0086] This invention also proposes a ring assembly process; please refer to [link / reference]. Figure 5 The ring assembly process includes: S11: The functional integration module 21 is installed into the constraint space formed by the support member 22 to form the integrated module 20; S21: Injection molding is performed on the integrated module 20, so that the injection molding material forms an outer ring 11 on the radially outer side of the support 22 and an inner ring 12 on the radially inner side, to form a smart ring 100.

[0087] In step 11, the operator first obtains the support member 22, which has multiple constraint edges 223, all of which together enclose a constraint space. The support member 22 can be made of plastic (such as liquid crystal polymer, polyetheretherketone) or composite material, has a certain rigidity, and its overall shape is a cage-like or fence-like structure, used to provide structural support for the functional integration module 21. The constraint edges 223 are arranged at intervals along the circumference of the smart ring 100, and through gaps are formed between adjacent constraint edges 223. These gaps can serve as channels for the flow of injection molding material during the subsequent injection molding process.

[0088] Simultaneously, the operator acquires the functional integration module 21, which is an assembly that uses a flexible circuit board as a mounting carrier and integrates electronic components such as a battery, information detection sensor, microprocessor, and wireless communication module. Because the flexible circuit board has bendable characteristics, its shape is unstable in a free state.

[0089] During the placement process, the surface of the constraint edge 223 will contact or be close to the outer edge of the functional integration module 21, guiding and limiting the circumferential and radial positions of the module, so that the functional integration module 21 naturally falls into the preset axial and radial positions.

[0090] The functional integration module 21 and the constraint edge 223 can be a clearance fit, a transition fit, or a slight interference fit to form a preliminary temporary fixation.

[0091] After the functional integration module 21 is placed into the support member 22, the functional integration module 21 is constrained from multiple directions by the constraint edge 223, preventing it from undergoing significant displacement, rotation, or warping during subsequent handling or assembly. This forms an integrated module 20 composed of the support member 22 and the functional integration module 21. Essentially, this step transfers the complex positioning operations that would normally be performed in the confined space inside the housing 10 to a spacious, open environment outside the housing 10, avoiding the deformation risks associated with directly manipulating the flexible circuit board in a limited space. Simultaneously, the support member 22 strengthens the structural form of the functional integration module 21, preventing deformation.

[0092] In step 21, the operator obtains the integrated module 20 formed in step S11 and places it as an insert into the cavity of the injection mold. The cavity of the mold is designed to accommodate the integrated module 20, with space reserved on its radially outer side for forming the outer ring 11 and space reserved on its radially inner side for forming the inner ring 12. The outer ring 11 forms the outer peripheral surface of the smart ring 100, and the inner ring 12 forms the inner peripheral surface of the smart ring 100. The outer ring 11 and the inner ring 12 are integrally formed with the support member 22 through an injection molding process. Their materials can be selected according to functional requirements. For example, the outer ring 11 can be made of hard plastic to provide structural protection and decoration, and the inner ring 12 can be made of soft thermoplastic elastomer to improve wearing comfort. The two can be formed separately through two-color injection molding or two-stage injection molding processes, or they can be formed in one step using the same injection molding material.

[0093] After the operator accurately places the integrated module 20 in the predetermined position of the mold, the mold is closed, and molten thermoplastic (such as polycarbonate, polyamide, thermoplastic polyurethane, or liquid crystal polymer) is injected into the mold cavity using an injection molding machine. The injection material flows under pressure. Due to the circumferential spacing of the constraint edges 223, the through gaps between adjacent constraint edges 223 provide a flow path for the injection material, allowing it to flow freely between the radially outer and radially inner spaces of the support member 22. This ensures that the injection material in the outer ring 11 and inner ring 12 areas is simultaneously and uniformly filled. During the flow process, the injection material fills the radially outer and radially inner spaces of the integrated module 20, respectively, and simultaneously makes close contact with the outer and inner surfaces of the support member 22. After the injection material cools and solidifies, an outer ring 11 is formed on the radially outer side of the support member 22, and an inner ring 12 is formed on the radially inner side. The outer ring 11 and inner ring 12 are bonded to the support member 22 through fusion bonding during the injection molding process, forming a strong integrated connection. During the curing process, the injection molding material physically interlocks with and even microscopically fuses with the surface of the support component 22, forming an inseparable integrated structure. After injection molding, the product is removed from the mold, resulting in a smart ring 100 with the outer ring 11, inner ring 12, and support component 22 integrally formed. The functional integration module 21 is securely encapsulated between the outer ring 11 and inner ring 12, and its flexible circuit board and electronic components are completely encapsulated and protected by the injection molding material. This step simultaneously forms the outer ring 11 and inner ring 12 through a single injection molding process, integrating them with the support component 22 and functional integration module 21 into a single unit. This eliminates the need for separate manufacturing and assembly of the outer ring 11 and inner ring 12 components, achieving integrated molding of the smart ring 100.

[0094] In some embodiments, between steps S11 and S21, an injection molding process can be used to encapsulate the functional integration module 21 and the support member 22 as a whole to further enhance the structural stability of the integrated module 20. Specifically, the pre-assembled semi-finished product is placed into an injection mold, and molten thermoplastic (such as polyamide, thermoplastic polyurethane, or liquid crystal polymer) is injected to fill the gap between the constraint edge 223 and the functional integration module 21. After cooling and solidification, a covering layer is formed. This covering layer firmly binds the functional integration module 21 and the constraint edge 223 together, forming an inseparable and structurally stable integrated module 20. After injection molding and solidification, the position of the functional integration module 21 in the support member 22 is locked, and its flexible circuit board is completely encapsulated and protected by the injection molding material. Even during the subsequent high-temperature and high-pressure injection molding process in step S21, no displacement or deformation will occur, further improving the reliability of the process and the durability of the product.

[0095] In some other embodiments, before placing the integrated module 20 into the injection mold, a tooling can be used to fix the functional integrated module 21 in the integrated module 20 relative to the support member 22. This tooling can apply clamping or positioning forces from the outside, ensuring that the functional integrated module 21 maintains a stable posture within the constraint space enclosed by the constraint edge 223, preventing relative movement due to vibration or impact under mold closing or injection pressure. The tooling can be removed after the integrated module 20 is placed into the mold and initially positioned, or it can work with the mold to complete the positioning function. With the assistance of the tooling, even if the integrated module 20 is only temporarily fixed in step S11 (such as with a clearance fit), it can maintain a high-precision relative position during the injection molding process in step S21, ensuring the accurate position of the functional integrated module 21 in the smart ring 100 after injection molding, thereby further improving product yield and consistency.

[0096] In this technical solution, the outer ring 11 and inner ring 12 are formed simultaneously through a single injection molding process, eliminating the need for separate manufacturing of the outer ring 11 and inner ring 12 and subsequent assembly. This significantly simplifies the production process and improves manufacturing efficiency, making it particularly suitable for mass automated production. Simultaneously, the injection-molded outer ring 11 and inner ring 12 achieve a seamless connection with the support component 22, eliminating the gaps or relative movement that may occur in separate assembly methods. This greatly enhances the overall structural strength and impact resistance of the smart ring 100, while also eliminating any abnormal noises or looseness that might result from gaps.

[0097] The present invention also proposes a ring kit, which includes a smart ring 100 as described above. For example, the ring kit includes a charging case and the smart ring 100 as described above. The charging case is used to store the smart ring 100 and charge the smart ring 100. The specific structure of the smart ring 100 is as described in the above embodiments. Since the ring kit proposed by the present invention adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0098] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
