Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to a smart ring device. Background Technology

[0002] Most smart ring devices have electrode pads on their inner ring for detecting skin conductance. However, since the inner ring is usually thin, stress concentration areas can form near the electrode pads. Furthermore, the inner ring is often made of resin. If the smart ring device is subjected to external impact, the aforementioned stress concentration areas are prone to cracking. These cracks can easily extend into the smart ring device, causing damage to the internal electronic components. Summary of the Invention

[0003] This application proposes a smart ring device, comprising: The housing assembly has an inner peripheral wall for contacting the user's finger skin when the smart ring device is worn. The inner peripheral wall includes an arcuate wall segment and a mounting wall segment, which are arranged circumferentially along the inner peripheral wall. An electrode sheet is disposed on the mounting wall section. The electrode sheet has an end face that contacts the inner peripheral wall in the circumferential direction. A mating surface is formed on the side of the electrode sheet facing away from the axis of the housing assembly. The mating surface extends from the end face to the middle of the electrode sheet. The mating surface is located inside the housing assembly; the distance between the mating surface and the axis of the housing assembly is less than or equal to the radius of the arc-shaped wall segment.

[0004] In some examples, the direction of the end face extension is offset relative to the axis of the housing assembly.

[0005] In some examples, the mating surface is a convex curved surface facing away from the axis of the housing assembly.

[0006] In some examples, in a section perpendicular to the axis of the housing assembly, the profiles of at least a portion of the mating surfaces lie on the same circumference as the profiles of the arcuate wall segments.

[0007] In some examples, protrusions and / or recesses are formed on the end face that are embedded within the housing assembly.

[0008] In some examples, the mounting wall segment includes a connecting segment that connects the end face and the arcuate wall segment; In this case, at least some of the connecting segments have a curvature greater than that of the arc-shaped wall segments.

[0009] In some examples, the connecting segment includes a first connecting segment and a second connecting segment. The first connecting segment is connected to the arcuate wall segment, and the second connecting segment is connected between the first connecting segment and the end face. The curvature of the first connecting segment is greater than the curvature of the second connecting segment, and the curvature of the first connecting segment is greater than the curvature of the arcuate wall segment.

[0010] In some examples, the second connecting segment is planar or near-planar.

[0011] In some examples, smart ring devices also include: An electronic component is disposed within a housing assembly. The electronic component includes a first circuit board located on the side of the electrode sheet facing away from the axis of the housing assembly. The electrode sheet includes a sheet body and a connecting portion. The end face and the mating surface are formed on the sheet body, and the connecting portion is used to connect the sheet body and the first circuit board.

[0012] In some examples, the electronic components also include: Second circuit board; Multiple light-emitting elements are disposed on one side of the second circuit board facing the axis of the housing assembly, and the light-emitting elements are electrically connected to the second circuit board; A light shield is disposed on one side of the second circuit board facing the housing assembly. Multiple light-emitting elements are located inside the light shield, and a light outlet is provided at the end of the light shield away from the second circuit board. A reinforcing rib is provided at the end of the light shield away from the second circuit board, and the reinforcing rib divides the light outlet into at least two light outlet sub-ports; Each photon port corresponds to at least one light-emitting element.

[0013] In some examples, there are multiple electrode sheets, which are arranged at circumferential intervals along the inner peripheral wall. Among them, at least two electrode plates are mirror-symmetric about the axial section of the housing assembly.

[0014] The smart ring device provided in this application embodiment can maintain a relatively large distance between the mating surface and the outer peripheral wall of the housing assembly. This keeps the mating surface and the aforementioned stress concentration area relatively far away from the electronic components inside the housing assembly. In the event of cracks appearing in the aforementioned stress concentration area, the mating surface can improve its guiding effect on the crack propagation direction, causing the crack to tend to propagate along the extension direction of the mating surface. This reduces the risk of the crack expanding significantly in the radial direction of the housing assembly. Consequently, it can reduce the probability of damage to electronic components when the smart ring device is subjected to external impact, which is beneficial to improving the user experience of the product.

[0021] In the description of this specification, the terms "one embodiment," "some embodiments," "specific embodiment," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0022] It should be noted that, referring to Figure 1 and Figure 2 Most smart ring devices have electrode pads 200 on the inner ring 120 for detecting skin conductance. However, since the thickness of the inner ring 120 is usually small, a stress concentration area 100c will form on the part of the inner ring 120 adjacent to the electrode pads 200 when the electrode pads 200 are provided. In addition, the inner ring 120 is often made of resin material. If the smart ring device is subjected to external impact, the aforementioned stress concentration area 100c is prone to cracking. This crack is easy to extend into the interior of the smart ring device, causing damage to the electronic components inside the smart ring device.

[0023] In view of this, such as Figures 3 to 11 As shown, an embodiment of this application proposes a smart ring device, comprising: a housing assembly 100 having an inner peripheral wall 100a, the inner peripheral wall 100a being used to contact the user's finger skin when the smart ring device is worn, the inner peripheral wall 100a including an arc-shaped wall segment 101 and a mounting wall segment 102, the arc-shaped wall segment 101 and the mounting wall segment 102 being arranged circumferentially along the inner peripheral wall 100a; an electrode sheet 200 disposed on the mounting wall segment 102, the electrode sheet 200 having an end face 201 that contacts the inner peripheral wall 100a circumferentially, a mating surface 202 formed on the side of the electrode sheet 200 facing away from the axis of the housing assembly 100, the mating surface 202 extending from the end face 201 toward the middle of the electrode sheet 200; wherein, the mating surface 202 is located inside the housing assembly 100; the distance R2 between the mating surface 202 and the axis of the housing assembly 100 is less than or equal to the radius R1 of the arc-shaped wall segment 101.

[0024] The smart ring device provided in this application embodiment includes the aforementioned housing assembly 100 and the aforementioned electrode sheet 200. The housing assembly 100 has an inner peripheral wall 100a for contacting the user's finger skin when the smart ring device is worn. The inner peripheral wall 100a includes a mounting wall segment 102 with the electrode sheet 200 and an arc-shaped wall segment 101 arranged circumferentially along the inner peripheral wall 100a with the mounting wall segment 102. In practical applications, an electronic component 300 is disposed inside the housing assembly 100; the end face 201 of the electrode plate 200 in the circumferential direction of the inner peripheral wall 100a is connected to the inner peripheral wall 100a, and the mating surface 202 formed on the side of the electrode plate 200 facing away from the housing assembly 100 is located inside the housing assembly 100. The mating surface 202 extends from the end face 201 towards the middle of the electrode plate 200, that is, the end of the electrode plate 200 in the circumferential direction of the inner peripheral wall 100a can contact and mate with the housing assembly 100 through the aforementioned end face 201 and mating surface 202. Correspondingly, a stress concentration area 100c is easily formed in the portion of the housing assembly 100 adjacent to the aforementioned end face 201 and mating surface 202; by setting the distance R2 between the mating surface 202 and the axis of the housing assembly 100 to be less than or equal to the specified distance, the electrical system can effectively prevent the electrical system from interfering with the electrical system. By using a method equal to the radius R1 of the arc-shaped wall segment 101, the smart ring device provided in this application embodiment can maintain a relatively large distance between the mating surface 202 and the outer peripheral wall 100b of the housing assembly 100. This makes the mating surface 202 and the aforementioned stress concentration area 100c relatively far away from the electronic components 300 inside the housing assembly 100. In the event of a crack appearing in the aforementioned stress concentration area 100c, the guiding effect of the mating surface 202 on the crack propagation direction can be improved, causing the crack to tend to propagate along the extension direction of the mating surface 202. This reduces the risk of the crack expanding significantly in the radial direction of the housing assembly 100, thereby reducing the probability of damage to electronic components when the smart ring device is subjected to external impact, which is beneficial to improving the user experience of the product.

[0025] It should be noted that in some designs, such as Figure 1 and Figure 2 As shown, the distance R2 between the mating surface 202 and the axis of the housing assembly 100 is greater than the radius R1 of the arc-shaped wall segment 101. If the radial distance between the outer peripheral wall 100b of the housing assembly 100 and the arc-shaped wall segment 101 is taken as the thickness of the housing assembly 100, then the smart ring device proposed in this application is compared with... Figure 1 and Figure 2The design shown allows the mating surface 202 and the aforementioned stress concentration region 100c to be relatively far away from the electronic component 300 inside the housing assembly 100, given a certain thickness of the housing assembly 100. It can also maximize the guiding effect of the mating surface 202 on the direction of crack propagation, causing the crack propagation direction to deviate from the radial direction of the housing assembly 100. This reduces the risk of cracks formed in the stress concentration region 100c propagating significantly towards the electronic component 300, thereby helping to reduce the probability of damage to the electronic component 300. Figure 2 and Figure 6 The arrow F in the diagram is used to schematically indicate the direction of crack propagation.

[0026] It should be noted that in this application, regarding Figure 1 and Figure 2 The description of the design shown is not limited. Figure 1 and Figure 2 The design shown is based on existing technology.

[0027] It should be noted that, Figure 1 , Figure 3 and Figure 8 The bounding box corresponding to the stress concentration region 100c does not indicate the specific size and shape of the stress concentration region 100c. It is only used to schematically indicate the location of the stress concentration region 100c. The specific size and shape of the stress concentration region 100c may vary due to factors such as the ring model and the composition of the resin on the inner wall.

[0028] It is understood that the housing assembly 100 has a ring-shaped structure, including an outer ring 110 and an inner ring 120 connected to the outer ring 110. The aforementioned inner peripheral wall 100a is the side of the inner ring 120 facing away from the outer ring 110, and the aforementioned outer peripheral wall 100b of the housing assembly 100 is the side of the outer ring 110 facing away from the inner ring 120. In practical applications, the outer ring 110 can be made of metal or resin, and the inner ring 120 can be made of resin. The aforementioned electronic component 300 is disposed between the inner ring 120 and the outer ring 110. The arc-shaped wall segment 101 is the main part of the inner peripheral wall 100a in the circumferential direction and extends in an arc direction. Correspondingly, the arc-shaped wall segment 101 is coaxial with the housing assembly 100. The mounting wall segment 102 is directly or indirectly connected to the arc-shaped wall segment 101 in the circumferential direction of the inner peripheral wall 100a.

[0029] It is understood that the electrode sheet 200 is partially embedded within the housing assembly 100 and partially protrudes from the inner peripheral wall 100a, so as to facilitate the fixing of the electrode sheet 200 and its contact with the user's finger skin when the smart ring device is worn. Both ends of the electrode sheet 200 in the axial direction of the inner peripheral wall 100a may have the aforementioned end face 201, that is, the electrode sheet 200 may have two end faces 201, such as... Figure 6 , Figure 10 and Figure 11 As shown, the aforementioned two end faces 201 include a first end face 2011 and a second end face 2012; correspondingly, a first mating surface 2021 and a second mating surface 2022 are formed on the side of the electrode sheet 200 facing away from the axis of the housing assembly 100, wherein the first mating surface 2021 extends from the first end face 2011 toward the middle of the electrode sheet 200, and the second mating surface 2022 extends from the second end face 2012 toward the middle of the electrode sheet 200.

[0030] It is understood that the aforementioned mating surface 202 extending from the end face 201 to the middle of the electrode sheet 200 means that one end of the mating surface 202 is connected to the end face 201 and the other end extends to the middle of the housing assembly 100, but it does not restrict the end of the mating surface 202 away from the end face 201 to be located in the middle of the electrode sheet 200.

[0031] Understandably, in order to further improve the stress concentration phenomenon in the stress concentration region 100c of the housing assembly 100, the end face 201 and the mating surface 202 can be rounded. Correspondingly, the formation of angular structures in the transition area between the end face 201 and the mating surface 202 of the housing assembly 100 can be avoided, which helps to reduce the stress concentration phenomenon in the stress concentration region 100c of the housing assembly 100.

[0032] like Figure 5 As shown, in some examples, the extension direction C1 of the end face 201 is offset relative to the axis of the housing assembly 100.

[0033] In this technical solution, the extension direction C1 of the end face 201 can be offset by a certain amount e from the axis of the housing assembly 100, that is, the extension direction C1 of the end face 201 and the axis of the housing assembly 100 do not intersect and are separated by a distance e. Based on the aforementioned setting, the extension direction C1 of the end face 201 is not radial to the housing assembly 100. Therefore, in the event of a crack appearing in the stress concentration area 100c, the end face 201 can further prevent the crack from being guided to propagate radially along the housing assembly 100, and can guide the crack to develop in a direction deviating from the radial direction of the housing assembly 100. Combined with the aforementioned setting of the mating surface 202, the crack can be concentrated in the shallow inner circumference area of ​​the housing assembly 100, further reducing the probability of damage to electronic devices and improving the user experience of the product.

[0034] It is understood that when end face 201 includes a first end face 2011 and a second end face 2012, the offset of the extension direction C1 of the aforementioned end face 201 relative to the axis of the housing assembly 100 refers to the offset of the extension direction of at least one of the first end face 2011 and the second end face 2012 relative to the axis of the housing assembly 100.

[0035] like Figure 6 and Figure 10 As shown, in some examples, the mating surface 202 is a convex curved surface facing away from the axis of the housing assembly 100.

[0036] In this technical solution, the mating surface 202 can be a convex curved surface facing away from the axis of the housing assembly 100. Based on the aforementioned configuration, the mating surface 202 can have a curved mating relationship with the housing assembly 100, thereby improving the smoothness of the fit between the mating surface 202 and the housing assembly 100 and reducing the stress concentration phenomenon in the aforementioned stress concentration region 100c. On the other hand, it can enhance the guiding effect of the mating surface 202 on the cracks that appear in the aforementioned stress concentration region 100c, which is conducive to the circumferential expansion of the cracks along the housing assembly 100 during the crack propagation process, thereby reducing the risk of the cracks expanding significantly into the radial direction of the housing assembly 100 in the stress concentration region 100c, and further reducing the probability of damage to electronic devices.

[0037] It is understood that when the mating surface 202 includes the first mating surface 2021 and the second mating surface 2022, the aforementioned mating surface 202 being a convex curved surface facing away from the axis of the housing assembly 100 means that at least one of the first mating surface 2021 and the second mating surface 2022 is a convex curved surface facing away from the axis of the housing assembly 100.

[0038] like Figure 6 As shown, in some examples, in a cross section perpendicular to the axis of the housing assembly 100, the profile of at least a portion of the mating surface 202 is located on the same circumference as the profile of the arcuate wall segment 101.

[0039] In this technical solution, the extension form and position of at least a portion of the mating surface 202 are constrained. Based on the aforementioned configuration, at least a portion of the mating surface 202 is an arc surface located on the same circumference as the arc-shaped wall segment 101. Correspondingly, the mating surface 202 can be surface-fitted with the housing assembly 100 through its arc-shaped portion, and the distance between the arc-shaped portion of the mating surface 202 and the outer peripheral wall 100b of the housing assembly 100 can be approximately equal to the thickness of the housing assembly 100. This improves the smoothness of the fit between the mating surface 202 and the housing assembly 100, reducing the stress concentration phenomenon in the aforementioned stress concentration region 100c; on the other hand... The mating surface 202 can enhance the guiding effect of the mating surface 202 on the cracks that appear in the stress concentration area 100c, which is conducive to the circumferential expansion of the crack along the shell assembly 100 during the crack propagation process, and reduces the risk of the crack expanding significantly in the radial direction of the shell assembly 100. On the other hand, it can make the thickness of the part of the inner ring 120 of the shell assembly 100 where the electrode sheet 200 is provided approximately the same as the thickness of the rest of the inner ring 120, ensuring the thickness uniformity of the inner ring 120, improving the load-bearing performance of the inner ring 120, and reducing the risk of cracking of the inner ring 120.

[0040] It should be noted that, Figure 6 The dashed line C2 in the diagram is used to schematically represent the circumference of the arc-shaped wall segment 101.

[0041] It is understood that when the mating surface 202 includes the first mating surface 2021 and the second mating surface 2022, the outline of at least a portion of the mating surface 202 and the outline of the arcuate wall segment 101 are located on the same circumference, which means that at least a portion of the outline of at least one of the first mating surface 2021 and the second mating surface 2022 is located on the same circumference as the outline of the arcuate wall segment 101.

[0042] In some examples, a protrusion and / or a recess 203 are formed on the end face 201 that are embedded in the housing assembly 100.

[0043] In this technical solution, the aforementioned protruding structure and / or recessed structure 203 can be formed on the end face 201, thereby increasing the contact area between the electrode sheet 200 and the inner ring 120 of the housing assembly 100, thereby enhancing the resin stability of the inner ring 120 near the electrode sheet 200, and thus reducing the risk of cracks in the aforementioned stress concentration area 100c when the smart ring device is subjected to external impact.

[0044] It is understood that when end face 201 includes the aforementioned first end face 2011 and second end face 2012, the formation of a protruding structure and / or a recessed structure 203 embedded in the housing assembly 100 on the aforementioned end face 201 means that at least one of the first end face 2011 and the second end face 2012 has the aforementioned protruding structure and / or recessed structure 203 formed. Specifically, as Figure 11 As shown, both the first end face 2011 and the second end face 2012 have recessed structures 203. Of course, it can be understood that both the first end face 2011 and the second end face 2012 can also have protruding structures; or, one of the first end face 2011 and the second end face 2012 has a recessed structure 203 and the other has a protruding structure; or, the first end face 2011 and the second end face 2012 have both the aforementioned protruding structure and recessed structure 203.

[0045] like Figure 3 , Figures 5 to 8 As shown, in some examples, the mounting wall segment 102 includes a connecting segment 1021 that connects the end face 201 and the arcuate wall segment 101; wherein at least a portion of the connecting segment 1021 has a curvature greater than that of the arcuate wall segment 101.

[0046] In this technical solution, the mounting wall segment 102 may include the aforementioned connecting segment 1021. Based on the aforementioned configuration, the mounting wall segment 102 can connect and transition between the end face 201 of the electrode sheet 200 and the arc-shaped wall segment 101 through the connecting segment 1021 with a larger curvature, which can improve the stress concentration phenomenon in the stress concentration area 100c, thereby reducing the risk of cracks in the aforementioned stress concentration area 100c when the smart ring device is subjected to external impact.

[0047] It is understood that the aforementioned first end face 2011 and the aforementioned second end face 2012 may both be connected to the aforementioned connecting segment 1021.

[0048] like Figure 8 As shown, in some examples, the connecting segment 1021 includes a first connecting segment 1021a and a second connecting segment 1021b. The first connecting segment 1021a is connected to the arcuate wall segment 101, and the second connecting segment 1021b is connected between the first connecting segment 1021a and the end face 201. The curvature of the first connecting segment 1021a is greater than the curvature of the second connecting segment 1021b, and the curvature of the first connecting segment 1021a is greater than the curvature of the arcuate wall segment 101.

[0049] In this technical solution, the connecting segment 1021 may include the aforementioned first connecting sub-segment 1021a and second connecting sub-segment 1021b. Based on the aforementioned configuration, the connecting segment 1021 can connect to the arc-shaped wall segment 101 through the first connecting sub-segment 1021a with a relatively large curvature, and connect to the end face 201 of the electrode sheet 200 through the second connecting sub-segment 1021b with a relatively small curvature. That is, the connecting segment 1021 has a curvature change in the direction from the arc-shaped wall segment 101 to the end face 201, which can realize a gradient curvature transition between the end face 201 of the electrode sheet 200 and the arc-shaped wall segment 101, thereby reducing the stress concentration phenomenon in the stress concentration area 100c of the housing assembly 100. When the smart ring device is subjected to external impact, it is beneficial to disperse the local concentrated stress in the housing assembly 100 and reduce the risk of cracks appearing at the connecting segment 1021.

[0050] It is understandable that the smooth transition between the first connecting segment 1021a and the second connecting segment 1021b can prevent stress sharp corners from forming in the transition area between the first connecting segment 1021a and the second connecting segment 1021b due to abrupt curvature changes.

[0051] In some examples, the second connector segment 1021b is planar or near-planar.

[0052] In this technical solution, by setting the second connecting segment 1021b to be planar or near-planar, the curvature of the second connecting segment 1021b can be relatively low, which facilitates a smoother connection transition between the second connecting segment 1021b and the end face 201 of the electrode sheet 200, reduces the stress peak at the connection between the connecting segment 1021 and the end face 201, and further helps to reduce the risk of cracks in the connecting segment 1021.

[0053] It is understandable that the aforementioned second connecting segment 1021b is planar or nearly planar, that is, the curvature of the second connecting segment 1021b is 0 or close to 0.

[0054] like Figure 5 , Figure 6 and Figure 9 As shown, in some examples, the smart ring device further includes: an electronic component 300 disposed within the housing assembly 100, the electronic component 300 including a first circuit board 310 located on the side of the electrode sheet 200 facing away from the axis of the housing assembly 100; wherein, the electrode sheet 200 includes a sheet body 210 and a connecting portion 220, an end face 201 and a mating face 202 formed on the sheet body 210, and the connecting portion 220 is used to connect the sheet body 210 and the first circuit board 310.

[0055] In this technical solution, the smart ring device may further include the aforementioned electronic component 300, and the electrode plate 200 may include the aforementioned plate body 210 and the connecting portion 220. Based on the aforementioned configuration, the connecting portion 220 can, on the one hand, support the plate body 210 on the first circuit board 310 and enable a certain gap to be formed between the plate body 210 and the first circuit board 310, thereby facilitating the plate body 210 to be positioned relatively close to the axis of the housing assembly 100. On the other hand, it can also realize the electrical connection between the plate body 210 and the first circuit board 310, facilitating signal transmission between the plate body 210 and the first circuit board 310.

[0056] It is understood that the connecting part 220 can be disposed on the side of the plate body 210 facing away from the axis of the housing assembly 100 and located in the middle of the plate body 210, thereby reducing the obstruction of the mating surface 202 by the connecting part 220, which is conducive to the mating surface 202 playing a crack guiding role and reducing the risk of damage to the electronic component 300; the connecting part 220 and the plate body 210 can be an integral structure, thereby reducing the manufacturing difficulty of the electrode plate 200; the connecting part 220 can be connected to the side of the first circuit board 310 facing the axis of the housing assembly 100.

[0057] Understandably, the chip body 210 is partially embedded within the housing assembly 100 and partially protrudes from the inner peripheral wall 100a, so that the chip body 210 can be fixed and contact the user's finger skin when the smart ring device is worn.

[0058] like Figure 5 and Figure 9 As shown, in some examples, the electronic component 300 further includes: a second circuit board 320; a plurality of light-emitting elements 330 disposed on one side of the second circuit board 320 toward the axis of the housing assembly 100, and the light-emitting elements 330 being electrically connected to the second circuit board 320; a light shield 340 disposed on one side of the second circuit board 320 toward the axis of the housing assembly 100, the plurality of light-emitting elements 330 being located inside the light shield 340, and a light-emitting port 3401 being provided at one end of the light shield 340 away from the second circuit board 320; and a reinforcing rib 350 disposed at one end of the light shield 340 away from the second circuit board 320, the reinforcing rib 350 dividing the light-emitting port 3401 into at least two light-emitting sub-ports 3401a; wherein each light-emitting sub-port 3401a corresponds to at least one light-emitting element 330.

[0059] In this technical solution, the electronic component 300 may further include the aforementioned second circuit board 320, light shield 340, reinforcing rib 350, and multiple light-emitting elements 330. The light shield 340 may be fixed to the second circuit board 320 by means of welding, gluing, snap-fitting, etc. Based on the aforementioned configuration, the light emitted by the light-emitting element 330 during operation can be directed to the inner peripheral wall 100a through the corresponding light-emitting port 3401a, and can then pass through the inner peripheral wall 100a to act on the user's finger skin, thereby facilitating optical detection of the user by the smart ring device. The light shield 340 can block the light emitted by the light-emitting element 330 that deviates from the light-emitting port 3401a, which helps to prevent light leakage from other surfaces of the housing assembly 100. The aforementioned reinforcing rib 350 can, on the one hand, divide the light-emitting port 3401 of the light shield 340 into multiple independent light-emitting ports 3401a, so as to configure relatively independent optical path channels for multiple light-emitting elements 330. On the other hand, it can also prevent the formation of a large-area and continuously distributed hollow structure on the light shield 340, thereby enhancing the structural strength of the light shield 340. This can prevent the light shield 340 from deforming, at least during the injection molding of the inner ring 120 and the installation of the light shield 340, which helps to ensure the production yield of the smart ring device.

[0060] It should be noted that in the production process of smart ring devices, electronic components 300 and electrode plates 200 are usually pre-assembled onto the outer ring 110 of the housing component 100, and then the inner ring 120 is injection molded. Due to the small size and thinness of the light shield 340, and the large number of light-emitting components 330, there are high requirements for the area of ​​the light outlet 3401 of the light shield 340. As a result, the structural strength of the light shield 340 is often low, and it is easy to deform during the injection molding of the inner ring 120, affecting the light shielding effect of the light shield 340. Based on the aforementioned setting of this technical solution, this application can strengthen the structural strength of the light shield 340 while dividing the light path using the reinforcing rib 350, and at least during the injection molding of the inner ring 120 and the installation of the light shield 340, it can prevent the light shield 340 from deforming.

[0061] Understandably, in practical applications, smart ring devices can use electrode pads 200 and the aforementioned light-emitting element 330 to perform skin electrical activity detection and optical detection on users, so as to collect a variety of different biological parameters of users.

[0062] Understandably, the reinforcing rib 350 and the light shield 340 can be a single integrated structure, which can reduce the processing difficulty of the smart ring device.

[0063] like Figure 5 and Figure 7 As shown, in some examples, there are multiple electrode plates 200, which are arranged circumferentially at intervals along the inner peripheral wall 100a; wherein at least two electrode plates 200 are mirror-symmetric about the axial section of the housing assembly 100.

[0064] In this technical solution, multiple electrode pads 200 can be provided on the inner peripheral wall 100a, and the multiple electrode pads 200 are arranged at intervals along the circumferential direction of the inner peripheral wall 100a. At least two of the multiple electrode pads 200 are arranged in a mirror-symmetrical manner with respect to the axial section of the housing assembly 100, so as to facilitate the smart ring device to collect changes in electrical signals within a certain range of the user's finger skin through multiple electrode pads 200 during use, thereby realizing the collection of the user's biological parameters.

[0065] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
