[0040] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0042] This invention provides a ring, which includes:

[0043] An annular body 1, having a first through hole 11;

[0044] The transmitting electrode group 3 and the receiving electrode group 4 are both disposed within the annular body 1.

[0045] The conductive elastomer 5, at least part of which is located in the first through hole 11 to be fixed on the annular body 1, is electrically connected to the transmitting electrode group 3 and the receiving electrode group 4. The conductive elastomer 5 is provided with a second through hole 53, which penetrates the conductive elastomer 5 and is coaxially arranged with the first through hole 11. The second through hole 53 allows the user's finger to pass through.

[0046] When the ring is worn on the user's first finger, the conductive elastomer 5, the user's first finger, and the second finger in contact with the user's first finger can together form a signal transmission path.

[0047] like Figures 1 to 3 As shown, the ring body 1 is the outer shell structure of the ring. The ring body 1 is usually designed with insulation to improve the security of wearing the ring. Figure 1 As shown, a first through hole 11 is provided on the annular body 1. The first through hole 11 is used for the user's fingers to pass through so as to facilitate wearing.

[0048] like Figure 1 and Figure 7 As shown, both the transmitting electrode group 3 and the receiving electrode group 4 are disposed within the annular body 1. For example, an accommodating space can be formed within the annular body 1, and the transmitting electrode group 3 and the receiving electrode group 4, etc., are disposed within the accommodating space within the annular body 1. This facilitates the arrangement of the transmitting electrode group 3 and the receiving electrode group 4, and also allows the annular body 1 to form a seal and protection for the transmitting electrode group 3 and the receiving electrode group 4, reducing interference from foreign objects to the transmitting electrode group 3 and the receiving electrode group 4, ensuring that the transmitting electrode group 3 and the receiving electrode group 4 can work normally, and also improving the structural reliability of the ring.

[0049] like Figure 1 and Figure 2 As shown, this embodiment of the invention also includes a conductive elastomer 5. At least a portion of the conductive elastomer 5 is located in the first through hole 11, that is, at least a portion of the conductive elastomer 5 is embedded in the annular body 1 and can be fixed on the annular body 1. This fully utilizes the internal space of the annular body 1, improving the space utilization rate of the ring and ensuring the aesthetics of the ring itself. The conductive elastomer 5 has a certain degree of elasticity, which can improve the comfort of the user when wearing it. The conductive elastomer 5 also has conductivity, and its conductivity is close to that of human skin. On the one hand, this allows the conductive elastomer 5 to form an electrical connection with the transmitting electrode group 3 and the receiving electrode group 4 to facilitate signal transmission, and on the other hand, it can also improve the safety of wearing the ring.

[0050] The conductive elastomer 5 is generally an annular structure to facilitate its adaptation to the annular body 1. The body 51 of the conductive elastomer 5 can be located in the first through hole 11, while the annular flanges 52 on both sides of the conductive elastomer 5 extend from the first through hole 11, so as to improve the reliability of the contact between the user's finger and the conductive elastomer 5 by utilizing the annular flanges 52 on both sides.

[0051] A second through hole 53 is provided on the conductive elastomer 5. The second through hole 53 penetrates the conductive elastomer 5 and is arranged coaxially with the first through hole 11. That is, both the first through hole 11 and the second through hole 53 are arranged along the axial direction of the annular body 1. The second through hole 53 allows the user's finger to pass through. Figure 3 As shown, when worn, the inner wall of the second through hole 53 can contact the user's finger. The contact effect between the conductive elastomer 5 and the user's finger can be adjusted by adjusting the size of the second through hole 53. For example, the size of the second through hole 53 can be appropriately reduced so that the user's finger can fully contact the conductive elastomer 5.

[0052] Furthermore, the conductive elastomer 5 is electrically connected to the transmitting electrode group 3, and the conductive elastomer 5 is electrically connected to the receiving electrode group 4, enabling signal transmission between the conductive elastomer 5 and the transmitting electrode group 3, and between the conductive elastomer 5 and the receiving electrode group 4. For example, the conductive elastomer 5 can be made to abut against the transmitting electrode group 3 and the receiving electrode group 4 to improve the reliability of the electrical connection between the conductive elastomer 5 and the transmitting electrode group 3, and between the conductive elastomer 5 and the receiving electrode group 4. This allows the transmitting electrode group 3, the conductive elastomer 5, the user's first finger, the second finger in contact with the user's first finger, and the receiving electrode group 4 to form a closed signal transmission path. This facilitates signal interaction with external terminals (such as VR, AR, PC, mobile phones, etc.) via the antenna group 7, meaning the ring can provide a hardware structure for signal interaction with external terminals.

[0053] like Figure 1 and Figure 2 As shown, the antenna assembly 7 can be housed within the annular body 1. The antenna assembly 7 includes an antenna 71, a fourth electrical connector 72, and an antenna bracket 73. The antenna bracket 73 is located at the top edge of the annular body 1, facilitating interaction between the antenna 71 and external terminals. Both the antenna 71 and the fourth electrical connector 72 are located within the annular body 1. The antenna 71 is fixed to the antenna bracket 73, and the antenna 71 is electrically connected to the circuit board 2 within the annular body 1 via the fourth electrical connector 72.

[0054] When a user wears a ring, for example Figure 3When a user wears a ring on their index finger (first finger) and their thumb (second finger) is in contact with it, the circuit board 2 emits a signal through the transmitting electrode group 3. This signal is transmitted sequentially through the conductive elastomer 5, the user's index finger, and the user's thumb to the receiving electrode group 4, and then back to the circuit board 2 through the receiving electrode group 4. This creates a closed signal transmission path between the transmitting electrode group 3, the conductive elastomer 5, the user's index finger, the user's thumb, and the receiving electrode group 4. When the user's thumb contacts, separates from, or slides on the index finger, the signal is turned on, disconnected, or its propagation path changes accordingly. Based on the changing signal transmitted by the receiving electrode group 4, the circuit board 2 can interact with external terminals (such as VR, AR, PC, mobile phones, etc.) through the antenna group 7, thereby realizing the interaction function between the user's finger movements and the external terminal.

[0055] Depending on the user's wearing needs, the ring can also be worn on other fingers, and the interaction between the user's finger movements and the external terminal can be achieved using the two fingers that can make contact.

[0056] Optionally, it also includes a shielding electrode group 6 and a circuit board 2. The transmitting electrode group 3 and the receiving electrode group 4 are electrically connected to the circuit board 2, respectively. The shielding electrode group 6 and the circuit board 2 are both located inside the annular body 1, and the two ends of the shielding electrode group 6 are respectively connected to the circuit board 2 and the conductive elastomer 5. The shielding electrode group 6 is used to isolate the transmitting electrode group 3 and the receiving electrode group 4.

[0057] like Figure 1 and Figure 7 As shown, both the circuit board 2 and the shielding electrode group 6 are located within the annular body 1. For example, an accommodating space can be formed within the annular body 1, and the circuit board 2 and shielding electrode group 6, etc., can be arranged within the accommodating space within the annular body 1. This facilitates the arrangement of the circuit board 2 and shielding electrode group 6, and also allows the annular body 1 to seal and protect the circuit board 2 and shielding electrode group 6, reducing interference from foreign objects on the circuit board 2 and shielding electrode group 6, ensuring that the circuit board 2 and shielding electrode group 6 can work normally, and improving the structural reliability of the ring.

[0058] The circuit board 2 can be a printed circuit board (PCB) to improve its strength; alternatively, it can be a flexible printed circuit (FPC), which utilizes its flexibility and bendability to adapt to different spatial requirements within the annular body 1, thus improving the layout flexibility of the circuit board 2. Furthermore, the transmitting electrode group 3 and the receiving electrode group 4 are electrically connected to the circuit board 2, enabling signal transmission between the transmitting electrode group 3 and the circuit board 2, as well as between the receiving electrode group 4 and the circuit board 2.

[0059] like Figure 7 As shown, one end of the shielding electrode assembly 6 is connected to the circuit board 2, and the other end is connected to the conductive elastomer 5, thus forming electrical connections between the shielding electrode assembly 6 and the circuit board 2, as well as between the shielding electrode assembly 6 and the conductive elastomer 5. Furthermore, the shielding electrode assembly 6 is located between the transmitting electrode assembly 3 and the receiving electrode assembly 4, thereby spatially isolating the transmitting electrode assembly 3 and the receiving electrode assembly 4 and preventing the signal emitted by the transmitting electrode assembly 3 from being directly transmitted to the receiving electrode assembly 4, thus ensuring the reliability of the ring's signal transmission.

[0060] Optionally, along the axial direction of the ring, the receiving electrode group 4, the shielding electrode group 6, and the transmitting electrode group 3 are arranged in sequence at intervals.

[0061] like Figure 7 As shown, in this embodiment of the invention, the receiving electrode group 4, the shielding electrode group 6, and the transmitting electrode group 3 are arranged sequentially and at intervals along the axial direction of the ring, so that the shielding electrode group 6 can be located between the transmitting electrode group 3 and the receiving electrode group 4. This allows the transmitting electrode group 3 and the receiving electrode group 4 to be spatially isolated by the shielding electrode group 6, preventing the signal emitted by the transmitting electrode group 3 from being directly transmitted to the receiving electrode group 4, thereby ensuring the reliability of the signal transmission of the ring.

[0062] In addition, the receiving electrode group 4, the shielding electrode group 6, and the transmitting electrode group 3 can be arranged at equal intervals, which can reduce the difficulty of arranging the receiving electrode group 4, the shielding electrode group 6, and the transmitting electrode group 3, facilitate the production and assembly of the ring, and also improve the structural symmetry of the ring.

[0063] The spacing between the receiving electrode group 4, the shielding electrode group 6, and the transmitting electrode group 3 can be adjusted according to the specific structure of the actual ring. This ensures that the shielding electrode group 6 provides good shielding between the transmitting electrode group 3 and the receiving electrode group 4, while also controlling the axial dimensions of the ring, which facilitates the miniaturization of the ring.

[0064] Optionally, an installation groove is provided on the inner wall of the first through hole 11, and the receiving electrode group 4, the shielding electrode group 6 and the transmitting electrode group 3 are all disposed in the installation groove.

[0065] Specifically, in this embodiment of the invention, three mounting slots can be provided on the inner wall of the first through hole 11, and the receiving electrode group 4, the shielding electrode group 6 and the transmitting electrode group 3 can be arranged in the mounting slots one by one. This facilitates the quick and reliable arrangement of the receiving electrode group 4, the shielding electrode group 6 and the transmitting electrode group 3, reduces the assembly difficulty of the ring, and also makes it easier to make full use of the internal space of the ring body 1, thereby improving the internal space utilization rate of the ring body 1.

[0066] In addition, by setting an installation groove on the inner wall of the first through hole 11 and placing the receiving electrode group 4, the shielding electrode group 6 and the transmitting electrode group 3 in the installation groove, it is also convenient for the conductive elastomer 5 located in the first through hole 11 to make full contact with the receiving electrode group 4, the shielding electrode group 6 and the transmitting electrode group 3 in the installation groove, thereby improving the reliability of the ring signal transmission.

[0067] Optionally, the annular body 1 also has a receiving cavity, which is connected to the mounting groove, and the circuit board 2 is located in the receiving cavity;

[0068] The emitting electrode assembly 3 includes an emitting electrode 31 and a first electrical connector 32. One end of the first electrical connector 32 is connected to the emitting electrode 31, and the other end of the first electrical connector 32 is connected to the circuit board 2.

[0069] The shielding electrode assembly 6 includes a shielding electrode 61 and a second electrical connector 62. One end of the second electrical connector 62 is connected to the shielding electrode 61, and the other end of the second electrical connector 62 is connected to the circuit board 2.

[0070] The receiving electrode group 4 includes a receiving electrode 41 and a third electrical connector 42. One end of the third electrical connector 42 is connected to the receiving electrode 41, and the other end of the third electrical connector 42 is connected to the circuit board 2.

[0071] like Figure 1 , Figure 6 and Figure 7 As shown, in this embodiment of the invention, the annular body 1 also has a receiving cavity for housing the circuit board 2 and the antenna group 7, thereby making full use of the internal space of the annular body 1 and improving the internal space utilization rate of the annular body 1. Furthermore, the receiving cavity is connected to the mounting slot, allowing the receiving electrode group 4, shielding electrode group 6, and transmitting electrode group 3 located in the mounting slot to fully contact the circuit board 2 located in the receiving cavity. This improves the reliability of the electrical connection between the receiving electrode group 4, shielding electrode group 6, and transmitting electrode group 3 and the circuit board 2, and also improves the reliability of signal transmission in the ring.

[0072] like Figure 1 , Figure 4 and Figure 7 As shown, the transmitting electrode group 3 may include a transmitting electrode 31 and a first electrical connector 32. The transmitting electrode 31 is connected to the conductive elastomer 5. One end of the first electrical connector 32 is electrically connected to the transmitting electrode 31, and the other end of the first electrical connector 32 is electrically connected to the circuit board 2, so that a signal transmission path can be formed between the circuit board 2, the first electrical connector 32, the transmitting electrode 31 and the conductive elastomer 5.

[0073] like Figure 1 , Figure 4 and Figure 7As shown, the receiving electrode group 4 may include a receiving electrode 41 and a third electrical connector 42. The receiving electrode 41 is connected to the conductive elastomer 5. One end of the third electrical connector 42 is electrically connected to the receiving electrode 41, and the other end of the third electrical connector 42 is electrically connected to the circuit board 2, so that a signal transmission path can be formed between the conductive elastomer 5, the receiving electrode 41, the third electrical connector 42 and the circuit board 2, thereby enabling it to cooperate with the transmitting electrode group 3 and interact with external terminals (such as VR, AR, PC, mobile phone, etc.) through the antenna group 7.

[0074] like Figure 1 , Figure 4 and Figure 7 As shown, the shielding electrode group 6 may also include a shielding electrode 61 and a second electrical connector 62. The shielding electrode 61 is connected to the conductive elastomer 5. One end of the second electrical connector 62 is electrically connected to the shielding electrode 61, and the other end of the second electrical connector 62 is electrically connected to the circuit board 2. This allows the shielding electrode 61 and the second electrical connector 62 to form an isolation between the transmitting electrode 31 and the receiving electrode 41, preventing the signal emitted by the transmitting electrode group 3 from being directly transmitted to the receiving electrode group 4, thereby ensuring the reliability of the signal transmission of the ring.

[0075] Among them, the first electrical connector 32, the second electrical connector 62 and the third electrical connector 42 are all electrical connection components, such as conductive pillars, conductive needles and other conductive components.

[0076] Optionally, the receiving electrode group 4 includes a receiving electrode 41, the shielding electrode group 6 includes a shielding electrode 61, and the transmitting electrode group 3 includes a transmitting electrode 31.

[0077] The receiving electrode 41, the shielding electrode 61, and the transmitting electrode 31 are all annular metal structures. The inner wall of the first through hole 11 has an annular groove, and the annular metal structure is correspondingly embedded in the annular groove. The inner wall of the annular metal structure abuts against the outer wall of the conductive elastomer 5.

[0078] like Figures 5 to 7 As shown, in this embodiment of the invention, the receiving electrode 41, the shielding electrode 61, and the transmitting electrode 31 are all annular metal structures. The mounting groove on the inner wall of the corresponding first through hole 11 is an annular groove, and the annular metal structure is embedded within it. This facilitates convenient and reliable assembly of the receiving electrode 41, the shielding electrode 61, and the transmitting electrode 31, reducing the assembly difficulty of the ring. Furthermore, by configuring the receiving electrode 41, the shielding electrode 61, and the transmitting electrode 31 as annular metal structures, they can be easily electrically connected to the circuit board 2 via corresponding electrical connectors. This also facilitates the flexible arrangement of the first electrical connector 32, the second electrical connector 62, and the third electrical connector 42.

[0079] Furthermore, the inner wall of the annular metal structure abuts against the outer wall of the conductive elastomer 5, meaning the annular metal structure is fitted onto the outer wall of the conductive elastomer 5. This ensures full contact between the receiving electrode 41, the shielding electrode 61, and the transmitting electrode 31 and the conductive elastomer 5. As a result, when the user wears the ring, any point of the conductive elastomer 5 that comes into contact with the corresponding electrode can generate a signal, thereby improving the reliability of the ring's signal transmission and enhancing the user's wearing comfort.

[0080] In addition, setting the shielding electrode 61 as a ring-shaped metal structure further enhances the shielding effect of the shielding electrode 61 between the transmitting electrode 31 and the receiving electrode 41, thereby further improving the reliability of the signal transmission of the ring.

[0081] Optionally, the conductive elastomer 5 has a hollow cylindrical structure, and both the first through hole 11 and the second through hole 53 are circular through holes, and the outer wall of the conductive elastomer 5 is in contact with the inner wall of the first through hole 11.

[0082] like Figure 1 , Figure 2 and Figure 7 As shown, in this embodiment of the invention, the conductive elastomer 5 is configured as a hollow cylindrical structure, that is, along the axial direction of the ring, the cross-section of the conductive elastomer 5 is a circular ring structure. The first through hole 11 on the annular body 1 and the second through hole 53 on the conductive elastomer 5 are both circular through holes, which facilitates the assembly of the conductive elastomer 5 and the annular body 1, and also makes it easier for the conductive elastomer 5 to adapt to the user's wearing.

[0083] The outer wall of the conductive elastomer 5 is designed to fit against the inner wall of the first through hole 11. For example, the diameter of the first through hole 11 can be reduced so that the conductive elastomer 5 can abut against the first through hole 11. This ensures that the conductive elastomer 5 is in full contact with the receiving electrode group 4, the shielding electrode group 6 and the transmitting electrode group 3 in the mounting groove of the first through hole 11, thereby improving the reliability of the ring's signal transmission.

[0084] Optionally, the conductive elastomer 5 includes a body 51 and an annular flange 52 connected to both sides of the body 51. The body 51 is located inside the annular body 1, and the annular flange 52 extends out from the first through hole 11.

[0085] like Figure 1 and Figure 7 As shown, the conductive elastomer 5 in this embodiment of the invention may include a body 51 and annular flanges 52 connected to both sides of the body 51. The body 51 is located inside the annular body 1 and is in contact with the inner wall of the first through hole 11 to ensure that the conductive elastomer 5 is in full contact with the receiving electrode group 4, the shielding electrode group 6 and the transmitting electrode group 3 in the mounting groove of the first through hole 11.

[0086] The annular flanges 52 on both sides extend from the sides of the first through hole 11. On the one hand, the annular flanges 52 on both sides can ensure the reliability and stability of the fit between the body 51 and the first through hole 11. On the other hand, the setting of the annular flanges 52 also avoids direct contact between the user's fingers and the annular body 1, improving the user's wearing comfort.

[0087] Optionally, the conductive elastomer 5 is a conductive foam elastomer, the conductivity of the conductive elastomer 5 is in the range of 1000 Ω·cm to 1500 Ω·cm, and the resistance of the conductive elastomer 5 after compression is in the range of 3% to 7%.

[0088] Specifically, in this embodiment of the invention, the conductive elastomer 5 is configured as a conductive foam elastomer, enabling it to conduct electricity. This allows the conductive elastomer 5, the user's first finger, and the second finger in contact with the first finger to collectively form a signal transmission path when the ring is worn on the user's first finger. Simultaneously, the conductive elastomer 5 also possesses sufficient elasticity to accommodate users with different finger sizes, thus increasing the ring's adaptability and ensuring wearing comfort.

[0089] The conductivity of the conductive elastomer 5 can be in the range of 1000 Ω·cm to 1500 Ω·cm, and the resistance of the conductive elastomer 5 after compression can be in the range of 3% to 7%. This ensures that the conductive elastomer 5 has good conductivity and elasticity, and its conductivity is close to that of human skin, thereby improving the reliability of the ring's signal interaction.

[0090] In one embodiment, the conductivity of the conductive elastomer 5 can be set to 1000 Ω·cm, and the change in resistance after compression of the conductive elastomer 5 is 5%. This ensures that the conductive elastomer 5 has good conductivity and good elasticity, thereby improving the reliability of the ring signal interaction and ensuring the stability of the conductive elastomer 5's own structure.

[0091] Optionally, the conductive elastomer 5 is made by foaming and vulcanizing a conductive material doped into an elastic substrate, the conductive material including at least one of carbon powder, silver powder, PEDOT and carbon nanotubes.

[0092] Specifically, in this embodiment of the invention, the conductive elastomer 5 can be made by doping conductive materials into an elastic substrate and then processing it through foaming and vulcanization. This allows the conductivity of the conductive elastomer 5 to be close to that of the user's finger, and it also has a good elastic compression ratio.
