[0003] Near-to-eye display includes VR (Virtual Reality), AR (Augmented Reality), MR (Mixed Reality), XR (Extended Reality), etc. Near-to-eye display can create a virtual image in a single eye or binocular field of view. Near-to-eye display renders light field information to the human eye through a display device placed in the non-visual distance of the human eye, and then reconstructs a virtual scene in front of the eye.

[0004] When using the above-mentioned device, it is often necessary to perform related interactive operations, such as sliding, switching, confirmation, etc. Most existing devices directly set mechanical buttons, etc. on the near-eye device shell to achieve interactive control. However, when the user is not easy or difficult to free both hands, the above-mentioned operation and interaction mode is relatively difficult, especially in complex and variable real-life environments, such as rain, sports, and various other scenarios. The resulting operation and device problems cause inconvenience to the user. On the other hand, there is an increasing demand for wearable devices that are more compatible with the hand, and production and manufacturing costs also need to be considered. SUMMARY

[0005] The present application provides a smart ring to solve at least one related technical problem of the incompatibility of existing devices with hand operation.

[0006] To achieve the above technical effects, one technical solution adopted by the present application is to provide a smart ring, comprising: a shell provided with a first through hole, the first through hole being adapted to accommodate a wearer's finger, the shell further being provided with a receiving cavity;

[0067] A battery 30 is located in the accommodating cavity 101, and the battery 30 is electrically connected with the flexible circuit board assembly 20 and supplies 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 non-rechargeable battery is also feasible.

In some embodiments, the processor 22 and the wireless transceiver 24 can be respectively located on both sides of the trigger assembly 40, thereby reducing the radio frequency interference of other electrical devices to the transceiver 24.

[0069] The cover seat 500 is sealingly connected with the shell 10, the material of the cover seat 500 and the material of the shell 10 can be the same or different, for example, a waterproof sealing rubber ring can be used or adhesive fixing can be used or glue filling can be used or secondary injection molding can be used to sealingly connect the cover seat 500 with the shell 10, thereby reducing the probability of water entering the accommodation cavity 101 through the connecting gap to damage the internal flexible circuit board assembly 20, battery 30 and trigger assembly 40 and other electrical devices, wherein the trigger assembly 40 includes a contact portion 41 and an electrical sensing portion 42, the projection area of the cover seat 500 in the first direction A is greater than the projection area of the contact portion 41 in the first direction A and allows the contact portion 41 to be physically contacted, and the flexible circuit board assembly 20, the battery 30 and the electrical sensing portion 42 are completely sealed in the accommodation cavity 101. It can be understood that the projection area can be the shape projection of the overall outer contour, the center can have a local hole, the first direction A can be the radial direction of the first through hole 12, as shown in FIGS. 2(a) and 2(b), the axial direction of the first through hole is B, and the radial direction and the axial direction can be perpendicular to each other, in some embodiments, the first direction A can also be the direction from the outer periphery of the first through hole 12 to the center. The outer contour area of the cover seat 500 can be greater than the outer contour area of the contact portion 41, the size of the cover seat 500 can be smaller than the size of the shell 10, from the perspective of the entire ring 100, the cover seat 500 can only occupy a part of the shell 10 in the circumferential direction, thereby greatly reducing the design of the cover seat 500 and reducing the production cost of the cover seat 500. During assembly of the ring 100, the flexible circuit board 20, the trigger assembly 40 and the battery can be placed into the accommodation cavity 101 first, then the cover seat 500 is assembled, and finally the cover seat 500 and the shell 10 are completely sealed. The above assembly can not use fasteners such as screws, so that the production cost and difficulty of the cover seat 500 can be reduced, the assembly efficiency can be improved and the cost can be reduced, in addition, the cover seat 500 can fully cover the contact portion 41 in all directions, for example, the contact portion 41 can be fully covered in the circumferential direction and / or the radial direction, regardless of whether the wearer is in motion, sweating, washing hands or using in a rainy environment, the above structure can reduce water entering the smart ring 100 through the assembly gap and improve the waterproof performance.

[0070] In some embodiments, the triggering component 40 comprises a contact portion 41, an electric sensing portion 42 and a button switch 46, the contact portion 41 is at least partially exposed relative to the cover seat 500; the contact portion 41 is configured to rotate relative to the shell 10 to trigger the electric sensing portion 42 and perform a first operation on the external device 200 and / or the device 300; the contact portion 41 is further configured to perform a first movement towards the first through hole 12 to trigger the button switch 46 and perform a second operation on the external device; the first operation is different from the second operation. Wherein the second operation and the first operation are different, for example, the first operation can be an interface operation of up and down pulling, up and down and left and right arbitrary selection or sliding, etc. related to content browsing, and the second operation can be an interface operation of yes or no, confirmation, play or pause, etc. related to functional decision. It can be understood that the rotation and the movement are both completed at the same position of the shell 10, that is, different actions can be realized at the same position of the shell 10 to realize different first operations and second operations on the external device, thereby reducing the probability that the user often needs to press different positions for operation, and improving the efficiency of remote interaction operation.

[0071] In some embodiments, the contact portion 41 is further configured to perform a second movement towards the first through hole 12 to trigger the button switch 46 and perform a third operation on the external device, the distance of the second movement is greater than the distance of the first movement, and the third operation is different from the second operation. For example, the first operation can be moving or sliding, the second operation can be currently selected (but not confirmed) but not selected for the time being, and the third operation can be final confirmation. Taking an interaction scenario of a charging application program as an example, the first operation corresponding to the rotation or sliding of the contact portion 41 can be the movement of the shooting area on the camera application graphical interface, the second operation corresponding to the first movement of the button switch 46 can be preliminary focusing, and the third operation corresponding to the second movement of the button switch 46 on the basis of the first movement can be final confirmation of shooting. The rotation, the first movement and the second movement correspond to the same region of the cover seat 500, for example, the rotation, the first movement and the second movement all correspond to a part of the arc of the cover seat 500, for example, a part of the arc of the cover seat 500, by concentrating all the actions at the same position, the settings of the keys and the like of other parts of the shell 10 can be effectively simplified, and the appearance of the ring can be more concise.

[0072] In some embodiments, referring to FIGS. 3, 5, 6, 8, 10 and 11, the flexible circuit board assembly 20 includes a flexible substrate 21 and a reinforcing plate 23 disposed on the substrate 21, wherein the reinforcing plate 23 has a strength greater than the flexible substrate 21, the substrate 21 can be straight before the design or installation to the housing 10, the substrate 21 is configured to allow bending and disposed along the circumference of the first through hole 12, the reinforcing plate 23 does not allow bending, the reinforcing plate 23 is multiple and disposed along the circumference of the first through hole 12 at intervals, the reinforcing plate 23 can be made of insulating material, thereby also reducing the electrical contact between the flexible substrate 21 and the inner housing 14. The processor 22 and / or the wireless transceiver 24 are located on the substrate 21 and supported by the reinforcing plate 23, the side of the reinforcing plate 23 away from the flexible substrate 21 can not be provided with any components, thereby the entire flexible substrate 21 can be attached to the inner wall of the housing 10. It can be understood that the flexible circuit board assembly 20 is disposed along the circumference of the first through hole 12, the processor 22, the wireless transceiver 24, the memory 28 and the peripheral electrical components 26 such as capacitors, resistors, inductors, light sources and the like are disposed on the flexible substrate 21 and electrically connected to each other, for example, by a single layer or multiple layers of printed electrical conductors of the flexible substrate 21, the battery 30 can power the above-mentioned electrical components. It can be understood that in order to reduce the risk of the above-mentioned electrical component soldering points falling off due to the bending of the flexible substrate 21 during assembly and use, the reinforcing plate 23 is added to the back of the flexible substrate 21 provided with electrical components, thereby avoiding the above-mentioned electrical components being bent, thereby improving the electrical stability of the entire electrical components and reducing the risk of damage to the electrical components during assembly and later use.

The push button switch 46 is located on the side of the first accommodating groove 102 away from the contact portion 41. The contact portion 41 is at least partially exposed relative to the cover seat 500. It can be understood that the cover seat 500 can be provided with a through hole 502, and the contact portion 41 is exposed relative to the through hole 502. The contact portion 41 is configured to allow movement in the first direction A to press the push button switch 46 and perform a second operation on the external device 200, 300. The movement in the first direction A can be understood as pressing the contact portion 41 directly in the first direction A or in a direction towards the center of the first through hole 12. The contact portion 41 abuts against the push button switch 46, thereby triggering the push button switch. When the contact portion 41 is not pressed, the contact portion 41 can be restored to the initial position by the elastic member 407 or the spring inside the push button switch 46. The second operation is different from the first operation. For example, the first operation can be an interface operation of up and down pulling, or any selection of up, down, left and right, or sliding, etc., which is a non-functional decision of content browsing. The second operation can be an interface operation of yes / no, confirmation, play or pause, etc., which is a functional decision.

[0074] In some embodiments, referring to FIG. 2(b), 8-12, the trigger assembly 40 can include an elastic support seat 44, which can be made of silicone or rubber or other materials that can rebound. The elastic support seat 44 is arranged in the first accommodating groove 102. The elastic support seat 44 is provided with a second accommodating groove 443. The electric sensing portion 42 includes a contact touch sensor 48, such as a capacitive or resistive touch sensor. The contact portion 41 includes a touch panel 47, which can be made of glass or plastic, etc. The electric sensing portion 42 and the contact portion 41 are arranged in parallel. The touch panel 47 is configured to receive a touch operation of a finger. The contact touch sensor 48 generates a signal according to the touch, and performs a first operation on the external device 200, 300. That is, after the finger touches different areas of the touch panel 47, the capacitance or resistance value of the corresponding different area of the contact touch sensor 48 will be affected. The processor 22 can send the value change of this area to the transceiver 24, and thus to the external device 200, 300, thereby realizing the first operation on the user interaction interface of the external device. The first operation can be referred to the above-mentioned embodiments.

[0075] In some embodiments, with reference to FIGS. 2(b), 8-12, the trigger assembly 40 can further include an adhesive layer 43, which can be formed by curing glue or the like, located between and bonding the contact portion 41 and the electrical sensing portion 42, the contact portion 41 is provided with a connecting post 401 on the side facing the electrical sensing portion 42, the adhesive layer 43 and the electrical sensing portion 42 are provided with second through holes 403, and the elastic support seat 44 is correspondingly provided with holes 444, the number and size of the holes 444 and the second through holes 403 can be the same, the connecting post 401 is fixedly connected to the contact portion 41 and the elastic support seat 44 by penetrating the second through holes 403 and the holes 444, and the button switch 46 is sealed in the second accommodating groove 443, so that when the contact portion 41 is pressed, the risk of water entering the second accommodating groove 443 to damage the button switch 46 is reduced. The button switch 46 is located on the side of the electrical sensing portion 42 away from the contact portion 41 and in the second accommodating groove 443, and the elastic support seat 44 is configured to be deformed by receiving the pressing of the contact portion 41 by the finger and triggering the button switch 46. It can be understood that the button switch 46 is located on the side of the electrical sensing portion 42 away from the contact portion 41, and after the contact portion 41 is pressed, the contact portion 41, the adhesive layer 43, the electrical sensing portion 42 and the button switch 46 are pressed and extruded as a whole to the elastic support seat 44, since the contact portion 41, the adhesive layer 43, the electrical sensing portion 42 and the button switch 46 are all rigid devices, they are not easy to be pressed and deformed, so the stroke pressing of the button switch 46 is realized by the deformation of the elastic support seat 44.

[0076] In some embodiments, referring to FIG. 2(b), 8-12, the elastic support base 44 can include a first surface 441 and a second surface 442 opposite to the first surface 441, the circumference of the first surface 441 is used to support the electric sensing part 42 and the contact part 41, the center of the first surface 441 is provided with a second accommodating groove 443, the bottom wall of the second accommodating groove 443 is in contact with the button switch 46; on the orthographic projection area of the second accommodating groove 443, the second surface 442 is provided with a convex part 446 and a concave part 445, the concave part 445 is arranged around the convex part 446, the convex part 446 is arranged corresponding to the button switch 46, the concave part 445 is described from the perspective of the second surface 442, the concave part 445 can be convex from the perspective of the first surface 441, in some embodiments, the concave part 445 can be wavy, in some embodiments, the concave part 445 can further include multiple segments arranged concentrically, the distance from the concave part 445 to the bottom wall of the first accommodating groove 102 is greater than the distance from the convex part 446 to the bottom wall of the first accommodating groove 102, wherein the convex part 446 and the bottom wall of the first accommodating groove 102 can directly abut, the first concave part 445 is configured to deform after the contact part 41 is pressed. The entire pressing process can be understood as follows: after the contact part 41 is pressed, the contact part 41, the adhesive layer 43, the electric sensing part 42 and the button switch 46 sink as a whole, the concave part 445 located at the outer circumference deforms to cause the outer circumference of the second surface 442 to move as a whole towards the first accommodating groove 102, while the convex part 446 corresponding to the button switch 46 still abuts the bottom wall of the first accommodating groove 102 without moving, along with the continuous pressing, the stroke of the button switch 46 is pressed to trigger the electrical signal, when the finger is no longer pressed, the elastic deformation of the concave part 445 recovers, and the contact part 41, the adhesive layer 43, the electric sensing part 42 and the button switch 46 return to the initial position as a whole. It can be understood that the present application adopts the contact type touch sensor 48 and the button switch 46 on different sides of the same axis, i.e. the button switch 46 is located at the back of the contact type touch sensor 48, so that the touch operation and the pressing operation can be realized in the same area to realize different interactive operations on the external device, without separately arranging the button switch 46 and the touch assembly 40, the internal space is fully utilized, and the structure of the ring as a whole is more compact. On the other hand, during the pressing process, the cover base 500 will not be pressed to move, and the cover base 500 and the shell 10 remain sealed and connected, so that the pressing process is still not easy to be affected by water and the like entering the internal battery 30 and the circuit board assembly 20.

[0077] In some embodiments, referring to FIG. 7(b), the contact portions 41 and the electrical sensing portions 42 are arranged along the circumference of the first through hole 12. It can be understood that the contact portions 41 and the electrical sensing portions 42 are located on the same radial line, and the contact portions 41 and the electrical sensing portions 42 are not spaced along the circumference of the first through hole 12. The central angle θ corresponding to the arc of the contact portions 41 and the electrical sensing portions 42 ranges between 25° and 90°, for example, 25°, 30°, 45°, 60°, 75°, 80°, 90°, etc. The button switch 46 includes one, i.e., for the contact portion 41 with a shorter arc. In some embodiments, the contact portions 41 and the electrical sensing portions 42 can both be arc-shaped, and a button switch 46 can be arranged on the side of the electrical sensing portion 42 away from the contact portion 41, which can ensure that the overall size is small.

[0078] In some embodiments, the central angle θ corresponding to the arc of the contact portions 41 and the electrical sensing portions 42 ranges between 60° and 90°, for example, 60°, 66°, 70°, 76°, 80°, 85°, 90°, etc. The button switch 46 includes two or more, and each button switch 46 is uniformly spaced along the circumference of the first through hole 12, wherein each button switch 46 has the same function. It can be understood that a longer arc can increase the area of the finger touch and improve the accuracy during the interaction. In addition, the plurality of spaced button switches 46 can ensure that the finger can be pressed on any contact portion 41 to achieve the same function. It can be understood that the degrees of the central angle θ in the above embodiments can be floating within a certain range according to actual needs, which will not be enumerated in detail here.

[0079] In some embodiments, referring to FIGS. 2(a), 3-6 and 7(a), the trigger assembly 40 of the ring 100 of the embodiments of the present application further includes a support plate 27. The support plate 27 can be made of rigid material, and the strength of the support plate 27 can be greater than that of the flexible substrate 21. The support plate 27 can also be rigid and have the same thickness as the reinforcing plate 23. The area of the support plate 27 can be greater than that of the reinforcing plate 23, so as to sufficiently support the electrical sensing portions 42 and the button switch 46. The support plate 27 is connected to the flexible substrate 21 and located in the first accommodating groove 102. The first accommodating groove 102 can have a flat bottom wall, so as to be adapted to the flat support plate 27. The support plate 27 can not be bent. The electrical sensing portions 42 and the button switch 46 are electrically connected to the flexible substrate 21 and supported by the support plate 27, which can ensure that the electrical welding installation of the electrical sensing portions 42 and the button switch 46 is more firm.

[0080] The contact portion 41 can further include a ball 410, a rotating portion 420, and a magnet 430.

The rotating portion 420 can be cylindrical or substantially cylindrical. The rotating portion 420 can have a roughness of 3-120 μm. The magnet 430 can be connected to the end of the rotating portion 420. The magnet 430 can be cylindrical or substantially cylindrical.

[0081] In some embodiments, referring to FIGS. 3-6 and 7(a), the support plate 27 is provided with a first hole 270. The charging interface 25 is electrically connected to the flexible substrate 21 through the first hole 270. The charging interface 25 is located on the side of the support plate 27 that is away from the contact portion 41 and the electric sensing portion 42. It can be understood that, since the button switch 46 is located on the side of the support plate 27 that faces the contact portion 41 and the electric sensing portion 42, the charging interface 25 can be arranged on the side of the support plate 27 that is away from the contact portion 41 and the electric sensing portion 42. Thus, the overall space can be fully utilized. In addition, since the processor 22 and the transceiver 24 are respectively located on the two sides of the triggering assembly 40, compared with arranging the charging interface at a distal position on the other circumferential direction, arranging the charging interface 25 directly below the support plate 27 (or the triggering assembly 40) can effectively shorten the electrical track layout and improve the electrical stability. In addition, by concentrating the charging interface 25 and other electrical components, the possibility of the overall thickness being too thick due to the arrangement of the charging interface 25 at other positions on the circumferential direction can be effectively reduced. The thickness of the entire shell 10 on the circumferential direction can have a gradual change in appearance, and the problem of the overall weight and volume being large due to maintaining a uniform thickness to be compatible with other positions can be effectively avoided.

[0082] Continuing to refer to FIGS. 3-6 and 7(a), in the first direction, which can be a radial direction along the first through hole 12 or a direction towards the center of the first through hole 12, the charging interface 25 does not overlap with the button switch 46 and the electric sensing portion 42. The charging interface 25 includes a metal column 250 that protrudes away from the support plate 27. During charging, for example, when the metal column 250 is used for charging, the physical contact of the charging interface 25 with the external charging seat will not cause physical extrusion to the electrical soldering points of the button switch 46 and the electric sensing portion 42 on the back. Thus, the stability of the soldering points of the button switch 46, the electric sensing portion 42, and the metal column 250 on the flexible substrate 21 on different sides can be effectively improved. The corresponding electrical soldering points are less likely to be loosened or damaged, so that the above-mentioned electrical devices have a longer service life.

[0083] In some embodiments, on the side of the flexible substrate 21 of the button switch 46 and the electric sensing part 42, the area corresponding to the metal column 250 in the first direction is not provided with an electric device. Thus, it is ensured that the metal column 250 does not cause looseness or damage to any relevant electric device during the charging process.

The electrical sensing part 51 can be attached to the first surface 547 of the first wall 541 and the first surface 547 of the second wall 542 by adhesion, etc., for example, thereby forming an adhesive layer 53. A second surface 548 of the first wall 541 and a second surface 548 of the second wall 542 are at least partially spaced apart from the arc-shaped base 44, wherein the first surface 547 and the second surface 548 can be two opposite surfaces, the first surface 547 faces the cover plate 600, and the second surface 548 faces the inner shell 14.

Among them, the first abutting portion 545 and the second abutting portion 546 can be located at the center position of the annular arc-shaped portion 544, and the first abutting portion 545 and the second abutting portion 546 can be opposite convex, concave, or a combination structure of convex and concave, etc. In other embodiments, the first abutting portion 545 can be the bottom wall of the second accommodating groove 543, and the second abutting portion 546 can be a convex. The second abutting portion 546 can be connected to the base 44, for example, abutting each other, that is, through the abutting support at the center position, the second surface 548 of the first wall 541 and the second surface 548 of the second wall 542 are spaced apart from the arc-shaped base 44.It can be understood that when the cover plate 600 is not pressed, the second surface 548 of the first wall 542 and the second surface 548 of the second wall 542 are both spaced apart from the bottom wall of the arc-shaped base 44, and the spacing is the largest.

Since the first abutting part 545 abuts against the button switch 56 and the second abutting part 546 is connected to the bottom wall of the base 44, the switch stroke of the button switch 56 is pressed to achieve electrical triggering. By arranging the button switch 56 on the side away from the electric sensing part 51 and cooperating with the elastic deformation of the elastic seat 54, the pressing and touching operations can be realized at the same time. The arrangement of the elastic seat 54 can effectively improve the user's pressing perception feedback. When the user presses the cover plate 600 to the position corresponding to the first wall 541 or the second wall 542, the pressing of the button switch 56 can still be effectively realized, and the pressing operation experience is improved.

The inner shell 14 is provided with a corresponding groove 162 at the position corresponding to the charging interface 25, and the projection of the first flexible substrate 211 and the second flexible substrate 221 at least partially overlapping each other and the position of the groove 162 correspond. Due to the overlapping part of the first flexible substrate 211 and the second flexible substrate 221, the thickness of the circuit board assembly at this position is thicker than other positions. The design of the groove 162 can ensure that the entire ring 100 has a uniform thickness in the circumferential direction, and on the other hand, it is also beneficial for the outer shell 16 to be pried open and clamped to the inner shell 14.

[0108] In some embodiments, the battery 30 and the circuit board assembly 20 are sealed and connected in the accommodation cavity 101, for example, the connection between the outer shell 16 and the support seat 80 can be sealed by glue, of course, the circuit board assembly 20, the battery 30 and the trigger assembly 40 can be sealed by glue after being installed to the inner shell 14, and then the outer shell 16 is sleeved to the cover plate 600 to complete the sealing. The sealed connection can effectively reduce the entry of water and other liquids into the battery or the circuit board assembly during the touch or pressing operation. In some embodiments, the assembly method of the ring 100 of the present application can be that the support seat 80 is connected to the first connecting part 18 through the second connecting part 81 to be fixed to the inner shell 14, the elastic seat 54 and the electric sensing part 51 are bonded on the first surface and the button switch 56 is accommodated in the second accommodation groove 543, the cover plate 600 is bonded to the second surface of the electric sensing part 51, the insulating seat 70 is clamped in the second hole 105, the first flexible substrate 211, the second flexible substrate 221 and the battery 30 are electrically connected around the inner shell 14, the charging interface 25 is clamped to the insulating seat 70, and the outer shell 16 can be appropriately pried open and sleeved to the outer periphery of the inner shell 14 due to the gap 161, and finally sealed by glue. Of course, the present application does not strictly follow the above assembly sequence for assembly, and the sequence can be adjusted according to the actual situation.

[0109] In some embodiments, referring to FIG. 13(b), 14-15 and 16(d), the circumferential bending arc of the electric sensing portion 51 corresponds to a central angle a of the circle ranging between 40°-55°, such as 40°, 41°, 43°, 45°, 50°, 51°, 53° or 55°, etc. A longer arc can increase the area of the finger touch and improve the accuracy during the interaction. The above embodiments regarding the degree of the central angle a can be within a certain range according to actual needs, which will not be listed in detail here. The electric sensing portion 51 includes a contact touch sensor, such as a capacitive or resistive touch sensor, which allows the user's finger to move arbitrarily within the corresponding area to achieve touch interaction with the external device 200. The cover plate 600 completely covers and is bonded to the electric sensing portion 51, thereby allowing the user to achieve touch operation on the electric sensing portion 51 when touching the cover plate 600. The cover plate 600 is configured to allow the electric sensing portion 51 to move synchronously relative to the shell 16 after the surface position of the cover plate 600 is pressed. It can be understood that there is a gap between the cover plate 600 and the shell 60. The cover plate 600 can be bonded to the electric sensing portion 51, and the cover plate 600 can also be partially clamped between the shell 16 and the support seat 80. When the cover plate 600 is pressed, the cover plate 600 and the electric sensing portion 51 are simultaneously pressed downward due to the elastic deformation of the elastic seat 54, thereby achieving the pressing of the stroke of the button switch 56. The cover plate 600 of the present application can move integrally. The complete projection area of the cover plate 600 corresponding to the electric sensing portion 51 and the bending provide a larger touch area, effectively improve the operation accuracy, and allow direct pressing of the cover plate 600 to achieve pressing operation, effectively improve the pressing feeling.

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 20. In some embodiments, an insulating layer or a protective layer (not shown in the figure) can be provided between the battery 30 and the inner shell 14, and between the battery 30 and the outer shell 16. The support seat 90 is connected with the inner shell 14, and the support seat 90 is provided with oppositely arranged first clamping parts 910.

The first clamping parts 910 and the second clamping parts 610 are connected with each other to cover the trigger assembly 50 between the cover plate 60 and the support seat 90. The first clamping parts 910 and the second clamping parts 610 can include mechanisms such as buckles, sliders, clamping parts, threads, pins, hooks, clamping grooves and / or combinations thereof to couple and / or fix the cover plate 60 and the support seat 90 together. The trigger assembly 50 is located between the cover plate 60 and the support seat 90. The first clamping parts 910 and the second clamping parts 610 are connected with each other through the opposite arrangement along the circumference, so that the connection along the entire circumference is more stable, effectively reducing the risk of loosening of the cover plate relative to the support seat during long-term pressing and / or touching the cover plate. The cover plate 60 is configured to receive external physical contact and allow the trigger assembly 50 to perform the first operation on the external device 200, 300. It can be understood that, for example, physical contact of the cover plate 60 by a finger causes the trigger assembly 50 to be electrically triggered and perform the first operation on the external device 200, 300; wherein the physical contact can include touching, rolling, sliding or pressing, etc. The physical contact can include static or dynamic single-point, multi-point, continuous or arbitrary contact or touch. The cover plate 60 covers the trigger assembly 50. As long as there is a trigger assembly 50 under the orthographic projection area of the cover plate 60, the execution of the first operation by the touch operation at any position can be realized. The first operation can realize the associated external device user graphical interface, such as up, down, left and right movement, pulling, sliding, page turning, confirmation selection, etc. For example, specific functions can include external device 200 and / or 300 page movement, volume adjustment, play / pause, like, long / short press selection, etc. The first operation can be a static, dynamic or static-dynamic combination user graphical interface display or function interaction of the graphical display interface of the external device.In some embodiments, the processor 22 and the wireless transceiver 24 can be located on two sides of the trigger assembly 50 respectively, thereby reducing the radio frequency interference of the wireless transceiver 24 by other electrical devices. 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 and spaced apart from the trigger assembly 50 respectively. By being arranged independently of the inner shell 14 by the support seat 90, the processing and mold opening cost of the shell 10 can be effectively reduced, and the circumferential bending of the support seat 90 and the cover plate 60 can accommodate a larger trigger assembly 50, effectively increasing the touch contact area of the trigger assembly 50 and improving the accuracy and reliability of the touch operation. In addition, the support seat 90 and the cover plate 60 are further connected to each other on the opposite sides in the circumferential direction by the first clamping portion 910 and the second clamping portion 610, further reducing the risk of the cover plate 60 being warped relative to the support seat 90 due to the user frequently operating one side, and effectively improving the product stability.

[0114] In some embodiments, referring to FIGS. 20, 22-23 and 24(a), the support seat 90 can include a base 94, and the first clamping portion 910 is located on opposite sides of the base 94.

After assembly, as shown in FIG. 20, the second arm 614 can abut against the clamping wall 915. During assembly, the second arm 614 on one side of the cover 60 can be clamped into the clamping hole 914, and since the clamping hole 914 can fully accommodate the second arm 614, the second arm 614 on the other side of the cover 60 can be clamped into the clamping hole 914 by means of the micro deformation of the cover 60 itself, so as to finally realize the clamping of the cover 60 and the support base 90 on the two opposite sides in the circumferential direction. Through the above-mentioned manner, even during long-term use, the second arm 614 is not easy to be pulled out of the clamping hole 914, thereby effectively reducing the risk of the cover 60 being lifted up relative to the support base 90.

It can be understood that the trigger assembly 50 is at least partially curved along the circumference of the inner shell 14, so that the cover plate 60 has a larger contact area to cover the trigger assembly 50. The support base 90 is curved in the circumferential direction, so that the first accommodating groove 92 has a larger accommodating space to accommodate a larger size trigger assembly 50. The larger trigger assembly 50 can effectively ensure a larger physical contact area, and the cover plate 60 is configured to receive external physical contact and allow the trigger assembly 50 to perform the first operation on the external device 200, 300.

In some embodiments, one or both of the first arc-shaped abutting surface 108 and the second arc-shaped abutting surface 912 are provided with grooves, so as to sufficiently accommodate the glue. It can be understood that the first arc-shaped abutting surface 108 and the second arc-shaped abutting surface 412 can be adhered by glue, and after the glue is cured, an adhesive layer 53 can be formed between the first arc-shaped abutting surface 108 and the second arc-shaped abutting surface 412. The thickness of the 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 seat 90 can be fixedly adhered to the inner shell 14. It can be understood that the adhesive layer formed by the connection of glue or double-sided adhesive tape and the like in the related embodiments of the present application is all shown by 53. It should be understood by those skilled in the art that the structure, size, shape, size, etc. of the adhesive layer 53 can be adjusted as needed, and will not be described here.

The light-transmitting column can be spaced apart from the second arc-shaped abutment. That is, the clamping of the light-transmitting column does not affect the bonding 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 by the light-transmitting column 411, so that the state of the smart ring 100 can be displayed, such as the state of the battery 30, the charging process, and the full charge, for example. For example, the light emitting device 29 displays red when the battery 30 is low, green when the battery 30 is fully charged, and flashes when the battery 30 is charging.

By providing the first recess 145 on the inner shell 14, the wall thickness of the inner shell 14 can be effectively reduced, and the light-transmitting efficiency can be effectively improved. Thus, light from the light emitting device 29 can be transmitted through the first recess 145.

It can be understood that pressing the cover plate 60 can squeeze the push button switch 56 to deform, and finally the switch stroke of the push button switch 56 is pressed to generate an electrical signal to the processor 22, and the processor 22 processes the signal and sends it to the external device 200 (such as a smart glasses or a mobile phone terminal) through the wireless transceiver 24, to realize the second operation control of the external device 200.

The above-mentioned physical separation can be understood as being physically blocked between the first accommodating groove 92 and the accommodating cavity 101. The first baffle 95 separates the light emitting device 29 and the trigger assembly 50 in the circumferential direction, and the light emitting device 29 and the trigger assembly 50 can be arranged on a common flexible circuit substrate, which can pass through the first baffle 45. The second baffle 96 separates the trigger assembly 50 and the battery 30, and the cover plate 60 is located between the first baffle 95 and the second baffle 96. The cover plate 60 can not be fixedly connected with the first baffle 95 and the second baffle 96, and the cover plate 60 can also not be fixedly connected with the outer shell 16. In some embodiments, glue sealing can be arranged at the connection between the first baffle 95, the second baffle 96 and the outer shell 16. In other embodiments, the components such as the battery 30 and the light emitting device 29 can be glued and cured in the accommodating cavity 101. After the smart ring 100 is assembled and formed, water and other liquids are not easy to enter the accommodating cavity 101 through the assembly gap between the cover plate 60 and the outer shell 16 due to the physical separation of the first baffle 95 and the second baffle 96.

The elastic seat is configured to be deformed by receiving physical pressing from the outside of the cover plate 60 and triggering the button switch 56 to perform the second operation on the external device 200, 300. It can be understood that pressing the cover plate 60 can squeeze the elastic seat 54 to deform, and finally drive the switch stroke of the button switch 56 to be pressed to generate an electrical signal to the processor 22, and the processor 22 processes the signal and sends it to the external device 200 (such as smart glasses or a mobile phone terminal) through the wireless transceiver 24, thereby realizing the second operation control of the external device 200.

The first flexible substrate 211 and the second flexible substrate 221 can be respectively provided with other basic components such as resistors 201, capacitors 202 or inductors, etc. The figures only show reference examples of the processor 22, the transceiver 24 and the basic components, which can be adjusted in position according to actual design needs. The first flexible substrate 211 and the second flexible substrate 221 at least partially overlap in the circumference 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 connected together by soldering and electrical plugging and then assembled to the housing 10. The strength of the reinforcing plate 213 is greater than that 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 long strips before early design or installation to the housing 10. When installed to the inner shell 14, the first flexible substrate 211 and the second flexible substrate 221 allow bending and are arranged along the circumference of the first through hole 12, the reinforcing plate 213 does not allow bending, the reinforcing plate 213 is a plurality of and is arranged at intervals along the circumference of the first through hole 12, the reinforcing plate 213 can be made of an insulating material, the reinforcing plate 213 located on the first flexible substrate 211 and the reinforcing plate 213 located on the second flexible substrate 221 can abut each other, thereby also reducing the electrical contact of the electrical components on the first flexible substrate 211 and the second flexible substrate 221.It can be understood that the circuit board assembly 20 is arranged along the circumference of the first through hole 12 as a whole, the processor 22, the wireless transceiver 24, the memory 28, and the peripheral electrical devices such as capacitors, resistors, inductors, light sources, etc. are arranged on the first flexible substrate 211 and electrically connected to each other, the charging interface 25, the capacitors, the 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 by using single-layer or multi-layer printed electrical conductors, and the battery 30 can supply power to the above-mentioned electrical devices. In some application scenarios, the above-mentioned electrical components are arranged on a whole flexible substrate, and then the flexible substrate is bent to realize that the charging interface 25 is on the inner side of the inner shell 14. This mode will cause the flexible substrate to be too long and the thickness after bending to be relatively thick.

[0126] In some embodiments, referring to FIGS. 13(a), 19(a), 20-22, and 25(b), the smart ring 100 can further include an insulating seat 70, which can be made of resin, plastic, rubber, or ceramic, etc. The inner shell 14 is further provided with a second hole 105, and the insulating seat 70 is sleeved on the outer circumference of the charging interface 25 and allows the charging interface 25 to be at least partially exposed relative to the inner shell 14, so that the external charging device can conveniently charge the battery 30 through the charging interface 25, and the insulating seat 70 is arranged in the second hole 105 and electrically insulates the charging interface 25 and the inner shell 14. The inner shell 14 can be made of metal material, and the charging interface 25 can be made of metal contact, for example, the charging interface 25 can include a central contact and a peripheral contact surrounding the central contact, one of which is positive and the other of which is negative, so that the external charger can charge through the charging interface 25. The insulating seat 70 is provided with a through hole 71, and the charging interface 25 is located in the through hole 71, so that the insulating seat 70 separates the charging interface 25 and the inner shell 14, thereby effectively avoiding electrical connection to the inner shell 14 during charging.

[0127] In some embodiments, the thickness of the shell 16 corresponding to the position of the charging interface 25 is less than the thickness of the shell 16 corresponding to the position of the battery 30. The shell 16 is provided with a corresponding second groove 162 at the position corresponding to the projection of the first and second flexible substrates 211 and 221 at least partially overlapping each other, and the position of the second groove 162. Due to the overlapping part of the first and second flexible substrates 211 and 221, the thickness of the circuit board assembly at this position is thicker than at other positions. The design of the second groove 162 can ensure that the entire ring 100 has a uniform thickness in the circumferential direction, and on the other hand, it is also beneficial for the shell 16 to be pried open and clamped to the inner shell 14.

[0128] In some embodiments, the battery 30 and the circuit board assembly 20 are sealed and connected in the accommodation cavity 101, and 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 parallel arrangements. The step 146 can be disconnected at the position corresponding to the abutting surface 143 (the first connecting part 18) to form the broken wall 147. The broken wall 147 is arranged on both sides of the first connecting part 18. The shell 16 is provided with a protruding part 163 on both sides of the gap 161, which protrudes towards the inner shell 14. The shell 16 is bonded with the step 146 and seals and connects the battery 30 and the circuit board assembly 20 in the accommodation cavity 101. It can be understood that a bonding layer can be formed by gluing at the connecting part of the step 146 between the shell 16 and the support seat 90. Of course, the circuit board assembly 20, the battery 30 and the trigger assembly 40 can be glued and sealed after being installed in the inner shell 14, and then the shell 16 is set corresponding to the cover plate 60 to complete the sealing. The sealed connection can effectively reduce the entry of water and other liquids into the battery or circuit board assembly during the touch or pressing operation. The protruding part 163 and the broken wall 147 are connected to each other, for example, abutting each other. One of the protruding parts 163 can include two and be arranged at intervals, so that the wires electrically connected between the electric sensing part 51 and the circuit board assembly 20 can pass through the middle of the interval. The shape of the other protruding part 163 can be the same or different. Since it is not necessary to allow the wires to pass through, the interval can not be provided. The above-mentioned abutting scheme can reduce the risk of rotation of the shell 16 relative to the inner shell 14, and is beneficial to the stable assembly of the shell 16 and the inner shell 14, and improves the installation efficiency.

[0129] In some embodiments, referring to FIGS. 19(b)-24(a), the battery 30 can include at least a first battery 32 and a second battery 34 electrically connected to each other, and the first battery 32 and the second battery 34 are arranged circumferentially along the inner shell 14. The first battery 32 can include one or more, and the second battery 34 can also include one or more, and the specific number can be adjusted according to the size or inner diameter of the inner shell 14. It can be understood that when referring to, for example, three or more batteries, the description can also be expressed as a first battery, a second battery, a third battery, and the like. The first battery 32 and the second battery 34 can be electrically connected to each other by a metal wire 36 or a metal contact or a welding point or an electrical socket, etc. 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 range between 30°-90°, for example, the central angle b and the central angle c corresponding to the circumferential curvature of the two types of batteries range, for example, 30°, 40°, 41°, 43°, 45°, 50°, 51°, 53°, 55°, 60°, 65°, 70°, 80°, or 90°, and the like. In some scenarios, if a battery 30 is directly used, the curvature of the battery will be fixed, and the smart ring has different sizes to adapt to different users, so it is difficult to install the battery with fixed curvature to the inner shell 14 with various sizes. It can be understood that the first battery 32 and the second battery 34 are not an integral whole, but are electrically connected by two or more separate batteries and are arranged circumferentially on the inner shell 14. The present application uses two types of batteries, namely 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 more other size or inner diameter shells 10, greatly improving the compatibility of the battery component, and effectively reducing the customization cost of the battery model.

[0130] In some embodiments, the present application can install the support seat 90 to the inner shell 14, then clamp the both ends of the cover plate 16 into the support seat 90 and bond the two, then surround the peripheral components such as the battery, the circuit board assembly, and finally set the outer shell 16 on the outer circumference of the inner shell 14 to cover the battery and the circuit board. Of course, the present application does not strictly follow the above assembly sequence, and the sequence can be adjusted according to the actual situation. The components of the present application are less, and the assembly is more firm, effectively improving the service life.

[0131] In some embodiments, referring to FIGS. 13(a), 20, 24(a) and 25(b), the circumferential bending arc of the electric sensing portion 51 corresponds to a central angle a of the circle ranging between 40° and 55°, such as 40°, 41°, 43°, 45°, 50°, 51°, 53° or 55°, etc. A longer arc can increase the area of the finger touch and improve the accuracy in the interaction process. The above embodiments regarding the degree of the central angle a can be varied within a certain range according to actual needs, which will not be further illustrated in detail here. The electric sensing portion 51 includes a contact touch sensor, such as a capacitive or resistive touch sensor, which allows the user's finger to move arbitrarily within the corresponding area range to realize the touch interaction with the external device 200. The cover plate 60 completely covers and is bonded to the electric sensing portion 51, thereby allowing the user to realize the touch operation on the electric sensing portion 51 when the cover plate 60 is touched. The cover plate 60 is configured to allow the electric sensing portion 51 to move synchronously relative to the shell 16 after the surface position thereof is pressed. It can be understood that the cover plate 60 is firmly connected to the support seat 90, and the cover plate 60 has a gap between the shell 16. The cover plate 60 can be bonded to the electric sensing portion 51, and the electric sensing portion 51 and the button switch 56 are embedded between the cover plate 60 and the support seat 90. When the cover plate 60 is pressed, the cover plate 60 and the electric sensing portion 51 are synchronously pressed as a whole to realize the pressing of the stroke of the button switch 56. When the cover plate 60 is touched, the electrical touch operation on the electric sensing portion 51 can be realized. The cover plate 60 of the present application can move as a whole. The cover plate 60 provides a larger touch area and bending corresponding to the complete projection area of the electric sensing portion 51, effectively improves the operation accuracy, and allows the cover plate 60 to be directly pressed to realize the pressing operation, effectively improving the pressing feeling.
