Description

Technical Field

[0001] This application relates to the field of wearable devices, and in particular to smart rings. Background Technology

[0002] Near-eye display includes VR (Virtual Reality), AR (Augmented Reality), MR (Mixed Reality), XR (Extended Reality), etc. Near-eye display can create virtual images in the field of vision of a single eye or binoculars. Near-eye display is a technology that uses a display device placed within the non-visual distance of the human eye to render light field information to the human eye, thereby reconstructing a virtual scene in front of the eyes.

[0003] When using the above-mentioned devices, it is often necessary to perform related interactive operations, such as sliding, switching, and confirming. During long-term use, the pressed parts of the existing devices are prone to loosening due to uneven force, which eventually leads to damage to the devices. Utility Model Content

[0004] This application provides a smart ring to address the technical problem of poor structural stability in existing devices.

[0005] To achieve the above-mentioned technical effects, one technical solution adopted in this application is: providing a smart ring, comprising: a housing, including an inner shell; a circuit board assembly having a processor and a wireless transceiver electrically connected to each other, the wireless transceiver being configured to communicate with at least one external device; a battery, the battery and the circuit board assembly being electrically connected to each other and connected to the inner shell; a support base connected to the inner shell, the support base having a first latching portion disposed opposite to each other; a triggering component disposed on the support base and electrically connected to the circuit board assembly; a cover plate, the cover plate and the support base both extending circumferentially along the inner shell, wherein the cover plate has a second latching portion disposed opposite to each other, the first latching portion and the second latching portion being arranged circumferentially along the inner shell, the first latching portion and the second latching portion being interconnected to cover the triggering component between the cover plate and the support base, the cover plate being configured to receive external physical contact and allow the triggering component to perform a first operation on the external device.

[0006] This application houses the circuit board assembly, battery, etc., within the inner shell, with a support base connected to the inner shell. A first latching portion is provided on the support base, and a trigger component is mounted on the support base and electrically connected to the circuit board assembly. Both the cover plate and the support base extend circumferentially along the inner shell, effectively increasing the touch contact area for the trigger component. A second latching portion is provided on the cover plate, with both the first and second latching portions arranged circumferentially along the inner shell. The first and second latching portions are interconnected, covering the trigger component between the cover plate and the support base. The cover plate is configured to receive external physical contact and allow the trigger component to perform a first operation on an external device. This application makes the circumferential connection between the cover plate and the support base more stable. The relative connection of the first and second latching portions further stabilizes the circumferential connection, effectively reducing the risk of the cover plate loosening relative to the support base.

[0026] See also Figure 1-14 This application provides a smart ring 100, including: a housing 10, the housing 10 further having a receiving cavity 101; the receiving cavity 101 is used to place various electrical components, etc. The housing 10 can be annular or arc-shaped with an opening, etc. During assembly or manufacturing, the housing 10 can be constructed from multiple sub-housings. The receiving cavity 101 is easily visible in the early stages of manufacturing. In the final product form, any excess space in the receiving cavity 101 can be partially or completely filled, for example, by applying glue or potting glue to partially or completely fill or seal it. In all these cases, it can be understood that the housing 10 has a receiving cavity 101. The housing 10 can include an inner shell 14 and an outer shell 16. The outer shell 16 is located on the outer periphery of the inner shell 14 and forms the receiving cavity 101. It can be understood that the inner shell 14 can have a receiving cavity 101, or the outer shell 16 can have a receiving cavity 101, or the inner shell 14 and the outer shell 16 can together form the receiving cavity 101. The inner shell 14 has a first through hole 12, which can be a polygon, a circle, a combination of an arc and a straight edge, or an arc with a notch. The first through hole 12 can accommodate the fingers of the wearer and is suitable for accommodating the wearer's fingers. The outer shell 16 has a notch 161. The circuit board assembly 20 is located in the accommodating cavity 101. The circuit board assembly 20 is provided with a processor 22 and a wireless transceiver 24. The processor 22 and the wireless transceiver 24 can be spaced apart and electrically connected. The processor 22 can be a microcontroller or microchip with processing capabilities, etc. The wireless transceiver 24 can use communication protocols such as Wi-Fi, Bluetooth, or 2.4G. In some embodiments, the processor 22 and the wireless transceiver 24 can also be integrated into the same chip. In this case, only the antenna of the wireless transceiver 24 needs to be brought out. The antenna of the wireless transceiver 24 can be a patch antenna or a ceramic antenna, etc. The wireless transceiver 24 is configured to communicate with at least one external device 200, external device 300. The external device 200 can be a near-eye or head-mounted device that can present digital content, such as smart glasses, augmented reality devices, virtual reality devices, or mixed reality devices. The external device 300 can also include terminals such as smartphones, computers, or tablets. In some embodiments, the external device 300 can also include remote servers, cloud computing, or databases, etc. It is understood that the electrical connection described in this application can be an electrical connection that is electrically conductive when energized and physically connected by wires or printed wires when not energized, or the electrical connection can also include wireless or radio frequency or electromagnetic induction coupling.

[0027] In some embodiments, the smart ring 100 may further include a memory 28 electrically coupled to the processor 22. The memory 28 optionally includes high-speed random access memory and also optionally includes non-volatile memory, such as one or more disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. The processor 22 and the memory 28 may be one or more, and the one or more processors 22 run or execute various software programs and / or instruction sets stored in the memory 28 to perform various functions of the device 100 and process data, which can be sent to external devices 200 and 300 to achieve interactive control of the external devices. It is understood that the smart ring 100 can communicate with the external device 200 to achieve user interface interaction with, for example, a mobile phone 300. The smart ring 100 and the external device (e.g., a near-eye device or smart glasses device 200) can communicate to achieve data transmission, interaction, etc., for example, to achieve user interface interaction with a near-eye device, without directly operating on the external devices 200 and 300 themselves.

[0028] The battery 30 and circuit board assembly can be connected to the inner shell, such as by bonding or snapping. The battery 30 can be located in the accommodating cavity 101. The battery 30 and the flexible circuit board assembly 20 are electrically connected and supply power to the processor 22 and the wireless transceiver 24. The battery 30 can be a rechargeable battery, such as a rechargeable lithium battery, etc. Of course, a disposable non-rechargeable battery is also feasible. The battery 30 can be arc-shaped, for example, arranged along the circumference of the first through hole 12. In some embodiments, an insulating layer or protective layer (not shown) can be provided between the battery 30 and the inner shell 14, and between the battery 30 and the outer shell 16. The support base 40 is connected to the inner shell 14. The support base 40 has a first latching portion 410 arranged opposite to each other, and the cover plate 60 has a second latching portion 610 arranged opposite to each other. Both the first latching portion 410 and the second latching portion 610 are arranged circumferentially around the inner shell 14, meaning they can be arranged opposite each other circumferentially to the inner shell 14. The number of the first latching portion 410 and the second latching portion 610 can be 2, 4, etc., and the number of the first latching portion 410 and the second latching portion 610 can be the same and maintain a one-to-one correspondence. The first latching portion 410 and the second latching portion 610 are interconnected to cover the trigger assembly 50 between the cover plate 60 and the support base 40. The first latching portion 410 and the second latching portion 610 may include mutually cooperating snaps, sliders, latching elements, threads, pins, hooks, slots, and / or combinations thereof to couple and / or fix the cover plate 60 to the support base 40. A trigger assembly 50 is located between the cover plate 60 and the support base 40. The relative arrangement of the first latching portion 410 and the second latching portion 610 in the circumferential direction makes the connection more stable throughout the circumferential direction, effectively reducing the risk of the cover plate loosening relative to the support base during prolonged pressing and / or touching of the cover plate. The cover plate 60 is configured to receive external physical contact and allow the trigger assembly 50 to perform a first operation on the external devices 200 and 300. It is understood that, for example, physical contact with the cover plate 60 by a finger causes the trigger assembly 50 to be electrically triggered and perform the first operation on the external devices 200 and 300; wherein the physical contact may include touching, rolling, sliding, or pressing, etc., and the physical contact may be static or dynamic, single-point, multi-point, continuous, or arbitrary contact or touch. The cover plate 60 covers the trigger component 50. As long as the trigger component 50 is located under the projected area of ​​the cover plate 60, a touch operation at any position can execute the first operation. The first operation can realize the user graphical interface of the associated external device, such as moving up, down, left, or right, dragging, swiping, page turning, confirming selection, etc. For example, specific functions may include page movement on external devices 200 and / or 300, adjusting volume, playing / pausing, liking, long press / short press selection, etc. The first operation can be a static, dynamic, or combined static and dynamic user graphical interface display or functional interaction on the external device.In some embodiments, the processor 22 and the wireless transceiver 24 can be located on opposite sides of the trigger component 50, thereby reducing radio frequency interference to the wireless transceiver 24 from other electrical components. In other embodiments, the processor 22 and the wireless transceiver 24 can be located on the same side, and the processor 22 and the wireless transceiver 24 can be electrically connected to the trigger component 50 and spaced apart. By setting the support base 40 independently of the inner shell 14, the processing and molding costs of the shell 10 can be effectively reduced. At the same time, the circumferential bending of the support base 40 and the cover plate 60 can accommodate a larger trigger component 50, effectively increasing the touch contact area of ​​the trigger component 50 and improving the accuracy and reliability of touch operation. In addition, the support base 40 and the cover plate 60 are further connected to each other on opposite sides in the circumferential direction by the first latching part 410 and the second latching part 610, further reducing the risk of the cover plate 60 tilting relative to the support base 40 due to frequent operation of one side by the user, effectively improving product stability.

[0029] In some embodiments, in conjunction with reference to Figure 4 , 6 -9. The support base 40 may include a base 44. First engaging portions 410 are located on opposite sides of the base 44. The cover plate 60 includes a cover body 61. Second engaging portions 610 are located on opposite sides of the cover body 61. The number of first engaging portions 410 and second engaging portions 610 is the same, and each includes at least two. For example, there are two first engaging portions 410, respectively located on opposite sides of the base 44; and two second engaging portions 610, respectively located on opposite sides of the cover body 61. Alternatively, there may be four first engaging portions 410 and four second engaging portions 610, spaced apart from each other. The number of both can remain the same. The first engaging portions 410 and second engaging portions 610 can engage with each other, effectively ensuring a secure connection between the cover plate 60 and the support base 40.

[0030] In some embodiments, the references continue to be used. Figure 4 , 6 -9, the first engaging portion 410 may include four engaging holes 414 disposed on opposite sides of the base 44, wherein two engaging holes 414 are located on the first side and the other two engaging holes 414 are located on the second side in the circumferential direction; the second engaging portion 610 includes four latches 620 disposed on opposite sides of the cover 61, wherein two latches 620 are located on the first side and the other two latches 620 are located on the second side in the circumferential direction; the latches 620 engage with the engaging holes 414 respectively. In some embodiments, such as Figure 7-8 The first latching portion 410 may further include a latching wall 415, which is spaced apart from the base 44, and a latching hole 414 is located between the base 44 and the latching wall 415; Figure 9The second latching portion 610 may further include a first arm 612 and a second arm 614, wherein a first end of the first arm 612 is connected to the cover 61, and a corresponding second end extends away from the cover 61; the second arm 614 is connected to the second end of the first arm 612 and is bent relative to the first arm 612; after assembly, as Figure 4 For example, the second arm 614 can abut against the snap-fit ​​wall 415. During assembly, the second arm 614 in the second snap-fit ​​portion 610 on one side of the cover 61 can be snapped into the snap-fit ​​hole 414. Since the snap-fit ​​hole 414 can fully accommodate the second arm 614, the second arm 614 in the second snap-fit ​​portion 610 on the opposite side of the cover 61 can then be snapped into the snap-fit ​​hole 414 by the slight deformation of the cover 61 itself, thus achieving the snap-fit ​​between the cover 60 and the support base 40 on opposite sides in the circumferential direction. In this way, even during long-term use, the second arm 614 is not easy to come out of the snap-fit ​​hole 414, thereby effectively reducing the risk of the cover 61 tilting relative to the support base 40.

[0031] In some embodiments, the inner shell 14 may be provided with a first connecting portion 18, and the support base 40 may be provided with a first receiving groove 42 and a second connecting portion 41 connected to the first connecting portion 18. The first receiving groove 42 can effectively reduce the material and weight of the support base 40. The first connecting portion 18 and the second connecting portion 41 may be connected by snap-fit, adhesive, or welding. The support base 40 may be made of plastic, and the inner shell 14 may be made of metal. Before the smart ring 100 is assembled, the support base 40 is an independent component relative to the inner shell 14, thus effectively reducing the complexity of the inner shell 14 and lowering the processing and molding costs of the inner shell 14. The trigger component 50 is at least partially located in the first receiving groove 42 and electrically connected to the circuit board assembly 20. It can be understood that a part of the trigger component 50 may be located within the first receiving groove 42, and another part of the trigger component 50 may protrude relative to the first receiving groove 42. The cover plate 60 is connected to the trigger assembly 50 and covers the notch 161. Both the cover plate 60 and the support base 40 are bent circumferentially along the inner shell 14. It can be understood that the trigger assembly 50 is bent at least partially along the inner shell 14, which effectively ensures that the cover plate 60 has a large contact area to cover the trigger assembly 50. The circumferential bending of the support base 40 allows the first receiving groove 42 to have a larger receiving space to accommodate a larger trigger assembly 50. The larger trigger assembly 50 can effectively ensure a larger physical contact area. The cover plate 60 is configured to receive external physical contact and allow the trigger assembly 50 to perform a first operation on the external devices 200 and 300.

[0032] In some embodiments, in conjunction with reference Figure 6-8In the first connecting portion 18, a first arcuate abutment surface 143 may be provided circumferentially along the inner shell 14. The second connecting portion 41 includes a second arcuate abutment surface 412. The first arcuate abutment surface 143 and the second arcuate abutment surface 412 are bonded to each other. The first arcuate abutment surface 143 is located on the inner wall on the side opposite to the first through hole 12 and may extend circumferentially along the inner shell 14. The second arcuate abutment surface 412 may be located on the side of the support base 40 opposite to the first receiving groove 42. The area of ​​the first arcuate abutment surface 143 and the second arcuate abutment surface 412 may be the same or different. The first arcuate abutment surface 143 and the second arcuate abutment surface 412 may be a partial surface contact ring area or a surface contact ring area composed of multiple points. In some embodiments, one or both of the first arcuate abutment surface 143 and the second arcuate abutment surface 412 form a groove, so as to fully accommodate the adhesive bonding. It is understood that the first arc-shaped contact surface 143 and the second arc-shaped contact surface 412 can be bonded together with adhesive. After the adhesive cures, an adhesive layer 53 can be formed between the first arc-shaped contact surface 143 and the second arc-shaped contact surface 412. The thickness of this adhesive layer 53 can be less than the thickness of the cover plate 60 and the inner shell 14, respectively, as long as the support base 40 can be fixedly bonded to the inner shell 14. It is understood that in the relevant embodiments of this application, the adhesive layer formed by adhesive or double-sided tape is exemplified by 53. Those skilled in the art should know that the structure, size, shape, and size of the adhesive layer 53 can be adjusted as needed, and will not be elaborated here.

[0033] In some embodiments, in conjunction with reference to Figure 5-8 10. The inner shell 14 may also be provided with a third connecting part 144 arranged opposite to each other, and the base 44 may also be provided with a fourth connecting part 48 arranged opposite to each other. The third connecting part 144 and the fourth connecting part 48 can be interlocked with each other. The number of the third connecting part 144 and the fourth connecting part 48 can be the same, for example, two or three of each. The third connecting part 144 can be a protruding structure, and the fourth connecting part 48 can be a groove or a through hole structure. During assembly, the support base 40 can be pre-fixed to the inner shell 14 through the connection between the third connecting part 144 and the fourth connecting part 48, which can effectively reduce the displacement of the two and ensure the assembly accuracy of other components. In addition, it can also effectively improve the stability between the support base 40 and the inner shell 14.

[0034] In some embodiments, combined with Figure 4-6In circuit board assembly 20, a light-emitting device 29 may be included. The light-emitting device 29 may include a light-emitting diode (LED), a micro LED, or an organic light-emitting diode, etc. The light-emitting device 29 and trigger assembly 50 are spaced apart and electrically connected to processor 22. In some embodiments, the first connection portion 18 includes a first through-hole (not shown), and the second connection portion 41 includes a light-transmitting column (not shown). The light-transmitting column is connected to the first through-hole and corresponds to the light-emitting device 29. The light-transmitting column can be spaced apart from the second arc-shaped abutment. That is, the snap-fit ​​of the light-transmitting column does not affect the adhesion of the second arc-shaped abutment. The light-transmitting column can be made of transparent or light-transmitting materials, such as transparent resin or plastic. Light from the light-emitting device 29 can be emitted through the light-transmitting column 411, thereby enabling the status display of the smart ring 100, such as the battery level, charging process, and full charge status of the battery 30. For example, the light-emitting device 29 displays red when the battery is low, green when fully charged, and flashes during the charging process, etc.

[0035] In some embodiments, in conjunction with reference to Figure 6 and 10 The inner shell 14 may also be provided with a groove 145. The inner shell 14 may be made of a light-transmitting material. The groove 145 is provided corresponding to the light-emitting device 29. The groove 145 and the light-emitting device 29 are provided to each other in the radial direction of the inner shell 14. For example, they are aligned with each other in the radial direction of the inner shell 14. The groove 145 may be provided at intervals with the third connecting part 144. By providing the groove 145 on the inner shell 14, the wall thickness of the inner shell 14 can be effectively reduced, and the light transmission efficiency can be effectively improved. Thus, the light from the light-emitting device 29 can be transmitted through the corresponding groove 145.

[0036] In some embodiments, continue to combine Figure 4-8The support base 40 may include an abutment portion 47 disposed on the base 44. The abutment portion 47 may be a protruding structure relative to the bottom wall of the base 44. The trigger assembly 50 also includes an electrosensor 51 and a push-button switch 56. The electrosensor 51 and the push-button switch 56 are electrically connected to the processor 22. The electrosensor 51 is bent circumferentially along the inner shell 14 and connected to the cover plate 60. The electrosensor 51 faces the cover plate 60, and the push-button switch 56 faces away from the cover plate 60. The abutment portion 47 and the push-button switch 56 abut against each other, that is, the electrosensor 51 and the push-button switch 56 are located on two different sides, so touch and press operations can be realized simultaneously. The cover plate 60 is configured to allow receiving external presses to trigger the travel deformation of the push-button switch 56 and perform a second operation on the external devices 200 and 300. The cover plate 60 is configured to receive external physical contact and allow the electrosensor 51 to perform a first operation on the external devices 200 and 300. It is understood that pressing the cover plate 60 can deform the button switch 56, ultimately causing the button switch 56 to be pressed, thereby generating an electrical signal to the processor 22. After processing the signal, the processor 22 transmits it to the external device 200 (such as smart glasses or a mobile phone terminal) via the wireless transceiver 24, realizing the second operation control of the external device 200. The second operation is different from the first operation. For example, the first operation can be a non-functional interface operation related to content browsing, such as pulling up or down, selecting freely up, down, left or right, or sliding on the external device 200. The second operation can be a functional interface operation related to the external device 200, such as yes / or, confirm, play or pause. Touching any area of ​​the electrosensor 51 below the front projection of the cover plate 60 realizes the electrical triggering of the electrosensor 51 to the processor 22, thereby executing the first operation (such as a movement selection operation). Pressing the button switch 56 below the front projection of the cover plate 60 realizes the electrical triggering of the button switch 56 to the processor 22, thereby executing the second operation (such as confirming an option). The abutting part 47 effectively increases the distance between the button switch 56 and the base 44, improving the tactile feedback during operation. It also facilitates pre-fixation when installed on the base 44, reducing the probability of positional shift during installation. The support base 40 can be made entirely of a translucent material, reducing the cost of separate manufacturing.

[0037] In some embodiments, the support base 40 may further include a first receiving groove 42, a first baffle 45 and a second baffle 46. The base 44 may be arc-shaped. The first receiving groove 42 is located between the first baffle 45 and the second baffle 46. The first receiving groove 42 may be formed by the bottom wall of the base 44, the first baffle 45 and the second baffle 46. The second connecting part 41 is located on the side of the base 44 away from the first receiving groove 42. The first baffle 45 physically separates the light-emitting device 29 and the triggering component 50 in the circumferential direction of the inner shell 14, and the second baffle 46 physically separates the triggering component 50 and the battery 30 in the circumferential direction of the inner shell 14. This physical separation can be understood as a physical barrier between the first receiving groove 42 and the receiving cavity 101. The first baffle 45 separates the light-emitting device 29 and the triggering component 50 in the circumferential direction. The light-emitting device 29 and the triggering component 50 can be disposed on a common flexible circuit board, through which the first baffle 45 can pass. The second baffle 46 separates the triggering component 50 and the battery 30. A cover plate 60 is located between the first baffle 45 and the second baffle 46. The cover plate 60 may not be fixedly connected to the first baffle 45 and the second baffle 46, nor may it be fixedly connected to the outer shell 16. In some embodiments, an adhesive seal can be provided at the connection between the first baffle 45, the second baffle 46, and the outer shell 16. In other embodiments, components such as the battery 30 and the light-emitting device 29 can be encapsulated and cured in the accommodating cavity 101. After the smart ring 100 is assembled, the physical barriers of the first baffle 45 and the second baffle 46 prevent liquids such as water from easily entering the accommodating cavity 101 through the assembly gap between the cover plate 60 and the outer shell 16.

[0038] In some embodiments, the trigger component 50 includes an electrical sensing unit 51 and a push-button switch 56. The trigger component 50 is located at a position corresponding to the notch 161, and the cover plate 60 covers the notch 161. The electrical sensing unit 51 and the push-button switch 56 are electrically connected to the processor 22. The push-button switch 56 can be a micro switch with a single or double press stroke, or a spring switch, or a pressure-sensitive switch, etc. The electrical sensing unit 51 can include a contact touch sensor, such as a capacitive or resistive touch sensor. That is, when a finger touches different areas of the cover plate 60, it will affect the capacitance or resistance value of the corresponding area on the contact touch sensor 51. The processor 22 can send the value change of this area to the transceiver 24, thereby sending it to the external devices 200 and 300, thereby realizing the first operation of the user interface on the external device. For the first operation, please refer to the relevant description of the above embodiments. The smart ring may also include an adhesive layer 53, which is located between the cover 61 and the electrical sensing part 51 and bonds the two together. The electrical sensing part 51 is bent circumferentially along the inner shell 14 and connected to the cover plate 60, for example, by adhesive or double-sided tape to form the adhesive layer 53. It is understood that the adhesive layer 53 involved in other related embodiments of this application may be the same or different adhesive materials. The figure only partially illustrates a reference example of the adhesive layer. In fact, the adhesive layer 53 may also be located between the second arcuate abutment surface 412 of the support base 40 and the first arcuate abutment surface 143 of the inner shell 14, the adhesive layer 53 may also be located between the cover plate 60 and the electrical sensing part 51, the adhesive layer 53 may also be located between the electrical sensing part 51 and the first wall 541 (described below), or the adhesive layer may also be located between the battery 30 and the inner shell 14, or the adhesive layer may also be located between the circuit board assembly 20 and the inner shell 14.

[0039] In some embodiments, the trigger assembly 50 further includes a resilient seat (not shown), which may be made entirely of silicone, rubber, or other resilient materials. The resilient seat is located between the electrical sensing unit 51 and the support base 40. The resilient seat has a second receiving groove. The push-button switch 56 is located on the side of the electrical sensing unit 51 opposite to the cover plate 60 and is at least partially located within the second receiving groove. The push-button switch 56 may be completely contained within the second receiving groove, or it may be partially located within the second receiving groove and partially protrude above it. The resilient seat is configured to receive external physical pressure on the cover plate 60, causing deformation and triggering the push-button switch 56 to perform a second operation on the external device 200, 300. It is understood that pressing the cover plate 60 can compress the resilient seat 54, ultimately pressing the push-button switch 56 to generate an electrical signal sent to the processor 22. The processor 22 processes this signal and transmits it to the external device 200 (e.g., smart glasses or a mobile terminal) via the wireless transceiver 24, thereby enabling second operation control of the external device 200. The second and first operations can be described with reference to the above embodiments.

[0040] In some embodiments, in conjunction with reference Figure 3-6In addition to 12, the circuit board assembly 20 also includes a first flexible circuit board 210 and a second flexible circuit board 220 that are electrically connected to each other. The first flexible circuit board 210 includes a first flexible substrate 211, and an electrical sensing part 51 and a push-button switch 56 are respectively disposed on different sides of the first flexible substrate 211, that is, the electrical sensing part 51 faces the cover plate 60 side and the push-button switch 56 faces the support base 40 side. The second flexible circuit board 220 includes a second flexible substrate 221 that is electrically connected to the battery 30 and the first flexible circuit board 210. The first flexible substrate 211 and the second flexible substrate 221 are further provided with reinforcing plates 213. The first flexible substrate 211 and the second flexible substrate 221 are configured to bend and are arranged circumferentially along the inner shell 14. The reinforcing plates 213 are not allowed to bend and there are multiple reinforcing plates 213 arranged at intervals along the circumferential direction of the inner shell 14. The processor 22 and / or the wireless transceiver 24 are connected to the first flexible substrate 211 and supported by the reinforcing plates 213, facing away from the inner shell 14. The second flexible substrate 221 is also provided with a charging interface 25. The charging interface 25 may include metal contacts or a USB interface, etc., which can be plugged into an external interface to charge the battery 30. In other embodiments, the charging interface 25 may also include a wireless induction coil, that is, a wireless charging transmitter can be used to wirelessly power it. In some embodiments, the charging interface 25 may also be provided with magnetic elements (not shown in the figure) at intervals, so that it can be easily magnetically attracted with an external charging cable or charging box for convenient and stable charging. The charging interface 25 is supported by the reinforcing plates 213 and faces away from the outer shell 16. Other basic components, such as resistors 201, capacitors 202, or inductors, may also be provided on the first flexible substrate 211 and the second flexible substrate 221. The figure is only a reference example of the processor 22, transceiver 24, and various basic components, and their positions can be adjusted according to actual design requirements. The first flexible substrate 211 and the second flexible substrate 221 overlap at least partially in the circumferential direction of the inner shell 14. It can be understood that the first flexible substrate 211 and the second flexible substrate 221 are two independent flexible substrates, which are electrically connected together by welding and then assembled into the shell 10. The strength of the reinforcing plate 213 is greater than the strength of the first flexible substrate 211 and the second flexible substrate 221. The first flexible substrate 211 and the second flexible substrate 221 can be elongated strips before being designed or installed into the housing 10. When installed into the inner housing 14, the first flexible substrate 211 and the second flexible substrate 221 are allowed to be bent and are arranged along the circumference of the first through hole 12. The reinforcing plate 213 is not allowed to be bent. There are multiple reinforcing plates 213, which are spaced apart along the circumference of the first through hole 12. The reinforcing plates 213 can be made of insulating material. The reinforcing plates 213 located on the first flexible substrate 211 and the reinforcing plates 213 located on the second flexible substrate 221 can abut against each other, thereby reducing the electrical contact of various electrical devices on the first flexible substrate 211 and the second flexible substrate 221.It is understood that the circuit board assembly 20 is arranged circumferentially along the first through hole 12. The processor 22, wireless transceiver 24, memory 28, and peripheral electrical components such as capacitors, resistors, inductors, and light sources are arranged on the first flexible substrate 211 and electrically connected to each other. The charging interface 25, capacitors, resistors, etc. are arranged on the second flexible substrate 221 and electrically connected to each other. The first flexible substrate 211 and the second flexible substrate 221 can be electrically connected using single-layer or multi-layer printed electrical wires. The battery 30 can supply power to the above-mentioned electrical components. In some application scenarios, the above-mentioned electrical components are arranged on a single flexible substrate, and then the flexible substrate is bent to make the charging interface 25 inside the inner shell 14. This method will result in the flexible substrate being too long and thick after bending. This application sets two independent first flexible substrates 211 and second flexible substrates 221, and the two can at least partially overlap in the circumferential direction relative to the inner shell 14, which can effectively reduce the length of the substrate and the thickness caused by bending, thereby effectively reducing the thickness between the inner shell 14 and the outer shell 16. In order to reduce the risk of solder joints of the electrical components falling off due to bending of the first flexible substrate 211 and the second flexible substrate 221 during assembly and use, a reinforcing plate 213 is added to the back of the first flexible substrate 211 and the second flexible substrate 221 on which the electrical components are located. This prevents the electrical components from being bent, thereby improving the electrical stability of the entire electrical component and reducing the risk of damage to the electrical components during assembly and subsequent use.

[0041] In some embodiments, in conjunction with reference Figure 2-6 10. The smart ring 100 may also include an insulating base 70, which may be made of resin, plastic, rubber, or ceramic. The inner shell 14 also has a second through hole 142. The insulating base 70 is fitted around the outer periphery of the charging interface 25, allowing the charging interface 25 to be at least partially exposed relative to the inner shell 14. This facilitates external charging devices charging the battery 30 through the charging interface 25. The insulating base 70, located in the second through hole 142, electrically isolates the charging interface 25 from the inner shell 14. The inner shell 14 may be made of metal, and the charging interface 25 may use metal contacts. For example, the charging interface 25 may include a center contact and peripheral contacts surrounding the center contact, where one of the center contact and the peripheral contact is positive and the other is negative. This allows charging via an external charger through the charging interface 25. The insulating base 70 has a through hole 71, and the charging interface 25 is located within the through hole 71. Thus, the insulating base 70 separates the charging interface 25 from the inner shell 14, effectively preventing electrical connection to the inner shell 14 during charging.

[0042] In some embodiments, the thickness of the outer casing 16 at the location corresponding to the charging interface 25 is less than the thickness of the outer casing 16 at the location corresponding to the battery 30. The outer casing 16 has a corresponding groove 162 at the location corresponding to the charging interface 25. The projection of the first flexible substrate 211 and the second flexible substrate 221 at least partially overlaps with each other and corresponds to the location of the groove 162. Since the overlap of the first flexible substrate 211 and the second flexible substrate 221 causes the circuit board assembly to be thicker at this location than at other locations, the design of the groove 162 can ensure that the entire ring 100 has a uniform thickness in the circumferential direction. On the other hand, it is also beneficial for the outer casing 16 to be pried open and snapped onto the inner casing 14.

[0043] In some embodiments, the battery 30 and circuit board assembly 20 are sealed within the accommodating cavity 101. The inner shell 14 is further provided with a step 146 and a broken wall 147. The step 146 can be arranged circumferentially along the inner shell 14, for example, two steps can be arranged in parallel. The step 146 can be broken at the position corresponding to the abutment surface 143 (first connecting part 18) to form the broken wall 147. The broken wall 147 is provided on both sides of the first connecting part 18. The outer shell 16 is provided with protrusions 163 on both sides of the notch 161. The protrusions 163 protrude towards the inner shell 14. The shell 16 is bonded to the step 146, sealing the battery 30 and circuit board assembly 20 within the accommodating cavity 101. It can be understood that an adhesive layer can be formed at the connection between the shell 16 and the support 40 by applying glue at the step 146. Alternatively, the circuit board assembly 20, battery 30, and trigger assembly 40 can be potted and sealed after installation into the inner shell 14, and then the shell 16 can be fitted onto the cover plate 60 to complete the seal. This sealed connection effectively reduces the entry of liquids such as water into the battery or circuit board assembly during touch or pressing operations. The protrusion 163 and the wall 147 are interconnected, for example, abutting against each other. One protrusion 163 may include two spaced apart, allowing the wires electrically connecting the electrical sensing unit 51 and the circuit board assembly 20 to pass through the gap. The shape of the other protrusion 163 can be the same or different; since allowing wires to pass through is not required, a gap is not necessary. The aforementioned mutual abutment scheme can reduce the risk of the outer shell 16 rotating relative to the inner shell 14, which is conducive to the stable assembly of the outer shell 16 and the inner shell 14 and improves installation efficiency.

[0044] In some embodiments, in conjunction with reference to Figure 13-14The battery 30 may include at least a first battery 32 and a second battery 34 electrically connected to each other, with the first battery 32 and the second battery 34 arranged circumferentially along the inner shell 14. The first battery 32 may include one or more, and the second battery 34 may also include one or more. The specific number can be adjusted according to the size or inner diameter of the inner shell 14. It is understood that when it involves three or more batteries, it can also be described as a first battery, a second battery, a third battery, etc. The first battery 32 and the second battery 34 can be electrically connected to each other via a metal wire 36, metal contacts, solder joints, or electrical connectors. The central angle b corresponding to the curvature of the first battery 32 and the central angle c corresponding to the curvature of the second battery 34 are respectively between 30° and 90°. For example, the ranges of the central angles b and c corresponding to the circumferential curvature of the two types of batteries are, for example, 30°, 40°, 41°, 43°, 45°, 50°, 51°, 53°, 55°, 60°, 65°, 70°, 80°, or 90°, etc. In some scenarios, if a single type of battery 30 is used, its curvature will be fixed. However, smart rings need to accommodate different users with different sizes, so batteries with fixed curvatures are difficult to install on inner shells 14 of various sizes. It is understood that the first battery 32 and the second battery 34 are not a whole, but rather two or more separate batteries electrically connected and arranged around the inner shell 14. This application uses two types of batteries, the first battery 32 and the second battery 34, which can make the curvature of the battery smaller, so that it can be installed on the shell 10 of more other sizes or inner diameters, greatly improving the compatibility and adaptability of the battery components and effectively reducing the customization cost of battery models.

[0045] In some embodiments, after the support base 40 is installed onto the inner shell 14, the two ends of the cover plate 16 are snapped into the support base 40 and bonded together. Then, the outer shell 16 is fitted around the battery, circuit board assembly, and other peripheral components, and finally, it is placed over the outer perimeter of the inner shell 14 to seal the battery and circuit board. Of course, this application does not strictly follow the above assembly sequence, and the sequence can be adjusted according to the actual situation. This application has fewer components, and the assembly is more robust, effectively improving the service life.

[0046] In some embodiments, in conjunction with reference Figure 3-4The central angle α corresponding to the circumferential curvature of the electrical sensing units 51 (9 and 11) along the inner shell 14 ranges from 40° to 55°, for example, 40°, 41°, 43°, 45°, 50°, 51°, 53°, or 55°, etc. A longer curvature can increase the area for finger touch and improve accuracy during interaction. The degree of the central angle α in the above embodiments can fluctuate within a certain range according to actual needs, and will not be detailed here. The electrical sensing unit 51 includes a contact touch sensor, such as a capacitive or resistive touch sensor, allowing the user's finger to move freely within the corresponding area to achieve touch interaction with the external device 200. The cover plate 60 completely covers the electrical sensing unit 51 and is bonded to it, thereby allowing the user to perform touch operation on the electrical sensing unit 51 when touching the cover plate 60. The cover plate 60 is configured to allow the electrical sensing unit 51 to move synchronously relative to the outer shell 16 when pressed at its surface position. It is understood that the cover plate 60 and the support base 40 are firmly connected, and there is a gap between the cover plate 60 and the outer shell 16. The cover plate 60 can be bonded to the inductive part 51. The inductive part 51 and the push-button switch 56 are embedded between the cover plate 60 and the support base 40. When the cover plate 60 is pressed, the cover plate 60 and the inductive part 51 are pressed down synchronously to realize the pressing of the push-button switch 56. When the cover plate 60 is touched, the electrical touch operation of the inductive part 51 can be realized. The cover plate 60 of this application can move relative to the entire body. The cover plate 60 corresponds to the full projected area and curvature of the inductive part 51, providing a larger touch area, effectively improving the accuracy of operation, and allowing direct pressing of the cover plate 60 to realize the pressing operation, effectively improving the pressing feel.

[0047] The accompanying drawings in this application are merely simplified examples to facilitate understanding of the overall assembly sequence or the material combinations of different components. The smart ring provided in this application may also include one or a combination of sensors such as vital signs sensors, position sensors, vibration sensors, or inertia sensors electrically connected to the processor 22, which can provide additional feedback or operational functions.

[0048] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
