When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.

[0036] Please see Figures 1 to 4 , Figure 1This is a schematic diagram of the overall structure of the revealed smart ring; Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure of the revealed smart ring; Figure 3 yes Figure 1 The diagram shows the overall structural breakdown of the smart ring. Figure 4 yes Figure 1 The schematic diagram of the circuit module revealed;

[0037] The smart ring 1000 includes an outer shell 200, a circuit module 100, and an inner shell 400. The outer shell 200, the circuit module 100, and the inner shell 400 are stacked sequentially, and the circuit module 100 is disposed in the receiving space formed by the outer shell 200 and the inner shell 400.

[0038] It should be noted that the outer casing 200 is made of non-metallic material, such as plastic, glass, ceramic, rubber, or nanomaterials, etc., and there are no specific limitations. It is understood that, unlike the metallic materials used in existing technologies, metallic materials are prone to causing significant interference to signal transmission and reception during use, often resulting in insensitive sensing. In this embodiment, the outer casing 200 is preferably made of ceramic material. The ceramic material used can increase the sensitivity and stability of electric field sensing. When a user touches the outer casing 200, the ceramic material of the outer casing 200 and the capacitor plate 301 of the circuit module 100 are used as capacitive sensing elements, forming an electric field on the surface of the outer casing 200. When a finger touches the outer casing 200, due to the conductivity of the human body, the electric field changes, thereby changing the capacitance at a certain location on the outer casing 200. The circuit module 100 accurately determines the touch location by monitoring the change in capacitance.

[0039] In this embodiment, the outer casing 200 is a smooth curved surface, and a touchable area 2011 is provided in at least a portion of the outer casing 200. The touchable area 2011 corresponds to the capacitor plate 301 of the circuit module 100. In similar prior art, windows or holes are usually provided in the outer casing 200 to install sensing components. However, this arrangement often results in limited sensing sensitivity. The performance of the sensing component is limited by the position and shape of the opening, especially when the sensing area is not completely fitted to the outer casing 200, which can lead to insufficient touch sensitivity or false touches. Furthermore, when the sensing component senses external signals through windows or holes, it is affected by the outer casing material (such as the metal shielding effect), resulting in a less than expected sensing effect. Moreover, the design of the window or hole affects the accuracy of touch sensing, especially in multi-touch or high-precision applications, where insufficient touch sensitivity or false touches may occur. Furthermore, the presence of windows or holes weakens the overall structural strength of the outer casing 200, especially in thin-walled designs or when the outer casing 200 material is brittle. This design may lead to damage, cracks, or deformation of the outer casing 200. Therefore, in this embodiment, the outer wall 201 of the housing 200 is a smooth curved surface. The outer wall 201 is firmly fitted with the capacitor plate 301 of the circuit module 100. Precise touch control can be achieved without opening windows and holes. In addition, while meeting the material strength requirements, the housing 200 is made of non-metallic material, which strengthens the signal transmission with the capacitor plate 301 to increase touch sensitivity.

[0040] In this embodiment, the smart ring 1000 is a ring. When wearing the smart ring 1000, the user's hand is in close contact with the inner shell 400, allowing for direct touch operation on the user's fingers. Due to its compact design and ergonomic construction, users can easily wear it in daily life without affecting normal hand movements. Users can control it with simple finger movements. For example, a user only needs to lightly touch the surface of the ring to complete basic operations such as swiping and clicking. This facilitates functions such as controlling smart devices and viewing notifications, avoiding the frequent picking up and operation of traditional touch devices (such as mobile phones and tablets). In other embodiments, the smart ring can also be a watch or a bracelet; there are no specific limitations.

[0041] Please refer to the following: Figure 4 , Figure 5 and Figure 6 , Figure 4 yes Figure 1 The schematic diagram of the circuit module revealed; Figure 5 yes Figure 1 The diagram illustrates the sliding motion of the smart ring within the touchable area. Figure 6 yes Figure 4 A schematic diagram of the capacitor plate structure;

[0042] In this embodiment, the length and width of the touch module 30 are adapted to the length and width of the housing 200 to expand the user's effective touch range and increase the touch sensitivity.

[0043] Furthermore, the touch module 30 is a rectangular strip structure. In other embodiments, the touch module 30 can have other shapes, and there are no specific limitations. The touch module 30 includes a capacitor plate 301 and a chip 302. The capacitor plate 301 is a capacitive touch sensor plate, which senses touch by changing the electric field. The human body is conductive, and when a finger touches or approaches the touch screen, a tiny change in the electric field is generated near the touch area. The capacitor plate 301 can detect this change and determine the touch position and intensity by the change in capacitance value. The chip 302 is a touch management chip 302, which is responsible for processing the signals from the capacitor plate 301 and converting them into digital information for transmission to the processor 10. The functions of the touch management chip 302 include signal processing, noise suppression, touch detection, multi-touch, anti-mistouch, and sensitivity adjustment, etc. The specific functions are not limited, and users can set them according to actual needs.

[0044] Furthermore, the capacitor plate 301 has at least two spaced capacitor units 3011, and a plurality of capacitor units 3011 are arranged in an array, with a first gap between the plurality of capacitor units 3011; adjacent plurality of capacitor units 3011 form a first gap region 3014 at the first gap.

[0045] It should be noted that the spacing between the capacitor units 3011 helps distinguish touch signals from different areas. When a user touches the screen, their finger affects the electric field of the contact area, causing a change in the capacitance value of the capacitor unit 3011. The touch management chip 302 identifies the touch location based on this capacitance change. Each capacitor unit 3011 can independently sense a touch, and multiple capacitor units 3011 interact to form a complete touch sensing grid, increasing the sensitivity and accuracy of touch detection.

[0046] Specifically, please refer to Figure 5 , Figure 5The area indicated by the arrow is the touchable area 2011. When a user's hand slides across the touchable area 2011, the hand touches the capacitive unit 3011. The capacitive unit 3011 or multiple capacitive units 3011 sense the change in capacitance to realize touch recognition operations such as swiping up, swiping down, single click, double click, and long press. It can be understood that one capacitive unit 3011 can realize the function of recognizing a single click or double click, while multiple capacitive units 3011 can realize the function of swiping up, swiping down, single click, double click, and long press.

[0047] It should be noted that the first gap area 3014 facilitates the user to bend and install the capacitor plate inside the housing.

[0048] It should be noted that the capacitor unit 3011 includes a first capacitor 3012 and a second capacitor 3013. The first capacitor 3012 and the second capacitor 3013 are combined to form the capacitor unit 3011, which is used to improve the sensing capability and anti-interference capability of the touch area. The first capacitor 3012 and the second capacitor 3013 of each capacitor unit 3011 can work independently or work together in the entire capacitor unit 3011 to sense touch or proximity signals in different areas. The shape and number of the capacitor units 3011 are not specifically limited.

[0049] It should be noted that a second gap is provided between the second capacitor 3013 and the first capacitor 3012 to facilitate the sensing of user touch recognition operations such as swiping left, swiping right, single click, double click, and long press.

[0050] Please see Figure 6 , Figure 6 yes Figure 4 The schematic diagram of the capacitor plate shows that, in this embodiment, the first capacitor 3012 and the second capacitor 3013 are triangular and diagonally arranged. The first capacitor 3012 and the second capacitor 3013 form the capacitor unit 3011, and the capacitor unit 3011 is arranged in an array.

[0051] Please see Figure 7 , Figure 7 yes Figure 4 Another embodiment of the capacitor plate is shown in the schematic diagram. In one embodiment, the capacitor unit 3011 can also be integrally arranged, and the capacitor unit 3011 can be arranged in an array.

[0052] Please see Figure 8 , Figure 8 yes Figure 4A schematic diagram of another embodiment of the capacitor plate is shown. In another embodiment, the first capacitor 3012 and the second capacitor 3013 are square and symmetrically arranged. The first capacitor 3012 and the second capacitor 3013 form the capacitor unit 3011, and the capacitor unit 3011 is arranged in an array.

[0053] It should be noted that in one of the capacitor units 3011, the second capacitor 3013 and the first capacitor 3012 are symmetrically arranged. This symmetrical arrangement helps to evenly distribute the electric field, ensuring that each capacitor unit 3011 can uniformly sense the touch point during a touch. Through this symmetrical design, the system can accurately detect the touch position, especially in multi-touch scenarios, ensuring that touch events are not affected by deviations. The symmetrical layout also enhances the symmetry of the electric field distribution, thereby reducing signal errors caused by uneven layout of the touchscreen area.

[0054] It should be noted that the first gap region 3014 and the second gap region 3015 can further isolate the signals of adjacent units, avoiding interference between the capacitor units. This gap design is crucial for improving the signal-to-noise ratio, reducing false touches, and enhancing touch sensitivity. The gap setting affects the electric field distribution of the touchpad; changes in the electric field at the gaps can effectively guide the touch signal, thereby improving signal accuracy.

[0055] In this embodiment, the range of the first gap area 3014 is 0.3mm to 2mm. Extensive experiments have shown that when the gap is greater than 2mm or less than 0.3mm, the sensing sensitivity decreases by about 40%. Therefore, the preferred range of the first gap area 3014 is 0.3mm to 2mm, which has the effect of increasing touch sensitivity.

[0056] In this example, the range of the second gap area 3015 is 0.3mm to 2mm. Extensive experiments have shown that when the gap is greater than 2mm or less than 0.3mm, the sensing sensitivity decreases by about 40%. Therefore, the range of the second gap area 3015 is preferably 0.3mm to 2mm, which has the effect of increasing touch sensitivity.

[0057] In this embodiment, the flexible circuit board 50 includes a flexible connection portion 501 and a circuit board 502. After the flexible connection portion 501 and the circuit board 502 are connected, an arc-shaped structure 503 is formed. The arc-shaped structure 503 formed by the flexible circuit board 50 includes an inner side surface 5031 and an outer side surface 5032 that are disposed opposite to each other.

[0058] It should be noted that the material of the flexible connection part 501 is polyimide (PI) film, polyester film, etc., and there is no specific limitation. Flexible materials not only have good electrical properties, but also have good bending resistance, high temperature resistance and tensile strength, which can meet the electrical connection requirements in different directions.

[0059] It should be noted that the flexible circuit board 50 uses a flexible connecting part 501 to connect the adjacent circuit board 502, which satisfies the material strength requirements while also allowing bending or winding within a limited space, thereby improving the compactness of the overall structural layout.

[0060] In this embodiment, the touch module 30 is disposed on the outer surface 5032 of the arc-shaped structure 503 via the flexible connecting portion 501. One end of the touch module 30 is connected to the circuit board 502 via the flexible connecting portion 501, while the other end of the touch module 30 is freely disposed. It is understood that the touch module 30 is disposed on the outer surface 5032 of the arc-shaped structure 503, and is located at the periphery of the circuit board 502, typically the most easily accessible area, facilitating touch input and ensuring convenient operation by the user.

[0061] In this embodiment, the chip 302 is sandwiched at the overlap between the capacitor plate 301 and the flexible circuit board 50. The chip 302 supports the capacitor plate 301 so that the capacitor plate 301 is connected to the outer surface of the arc-shaped battery 70 to form a smooth curved surface.

[0062] It should be noted that the chip 302, sandwiched at the overlap between the capacitor plate 301 and the flexible circuit board 50, primarily supports the capacitor plate 301 and provides it with electrical connection. The chip 302 not only performs signal processing but also physically supports the capacitor plate 301, ensuring it remains stably positioned in the predetermined location within the circuit design. Supported by the chip 302, the capacitor plate 301 can connect seamlessly with the outer surface of the curved battery 70, forming a smooth curved surface. This ensures a smooth interface between the capacitor plate 301 and the device surface, increasing structural strength without compromising the overall aesthetics of the device.

[0063] In this embodiment, the circuit module 100 also includes at least one of the following structures: Bluetooth module, motion sensor module, temperature sensor module, charging management module, optical sensor module 80, and vibration module. The specific structure is not limited, and it can realize functions such as heart rate detection, blood oxygenation, step counting, detection of human body surface temperature, and human-computer interaction.

[0064] In this embodiment, the outer shell 200 includes an outer wall 201 and a side wall 202, and the inner shell 400 includes a second inner wall 202 and a second outer wall 402. The second inner wall 202 has a filling portion formed in the direction away from the outer shell 200. The filling portion is provided with a convex bulge. The convex bulge is provided with a light shield 401. The convex bulge corresponds to any one of the structures of the Bluetooth module, motion sensor module, temperature sensor module, charging management module, optical sensor module 80, and vibration module of the circuit module 100. The second inner wall 202 is connected to the second outer wall 402. The circuit module 100 is disposed between the second inner wall 202 and the side wall 202 to fix the circuit module 100.

[0065] Furthermore, the material of the convex bulge can be resin, plastic, silicone, rubber, or other materials.

[0066] Furthermore, the inner shell 400 is made of non-metallic material.

[0067] Compared to existing technologies, by using a non-metallic outer shell 200, a flexible circuit board 50 is mounted on the outer shell 200, and a foldable touch module 30 is mounted on the flexible circuit board 50. The touch module 30 is equipped with multiple spaced-apart capacitor units 3011, enabling precise touch sensing. Furthermore, the touch module 30 is fitted snugly to the non-metallic outer shell 200, eliminating the need for openings or holes in the outer shell 200, thus improving touch accuracy and reducing production costs.

[0068] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
