Description

Technical Field

[0001] This application relates to the field of wearable device technology, and in particular to a ring casing and a smart ring. Background Technology

[0002] A smart ring is a wearable device worn on a user's finger that can have functions such as health management, exercise monitoring, and communication.

[0003] In related technologies, the finger size of smart rings is often difficult to adjust, making it difficult for smart rings to accurately fit fingers of different sizes. Summary of the Invention

[0004] This application provides a ring casing and a ring to solve the problem of difficulty in adjusting the finger size of smart rings in the prior art.

[0005] A first aspect of this application provides a ring casing, which includes a casing body. The casing body has a ring-shaped structure and includes a first end and a second end, which are slidably connected. The casing body is made of a shape memory alloy, and when the casing body deforms, the first end can slide relative to the second end along the extending direction of the casing body.

[0006] The ring casing provided in this application embodiment is made of shape memory alloy. By changing the temperature, the casing body can transition between austenitic and martensitic phases. Utilizing the elastic changes of the casing body in these phases, the shape of the casing body can be easily adjusted and stably maintained. This allows for adjustment and maintenance of the smart ring's finger circumference. Consequently, the ring circumference can be easily adjusted according to the user's finger size, ensuring accurate fit and stable wear. This meets the needs of users with varying finger sizes and reduces the difficulty of manufacturing, managing, and selling smart rings.

[0007] In addition, the outer shell is made of shape memory alloy, which makes it easy to adjust the overall shape of the outer shell and maintain the adjusted shape relatively stably. In other words, when adjusting the finger size of the smart ring, both the inner and outer diameters of the smart ring can be adjusted, which can reduce the thickness change of the smart ring during the finger size adjustment process. This makes it less likely that the gap between the finger wearing the smart ring and the adjacent fingers will change significantly, and the squeezing sensation of the smart ring on the adjacent fingers will not change significantly, which helps to improve the comfort of wearing the smart ring.

[0008] Furthermore, the sliding connection between the first and second ends, and the fact that the first end can slide relative to the second end along the extension direction of the outer shell body, allows the ring size to be changed by deforming the outer shell body while maintaining the ring-shaped form of the ring shell, minimizing changes in the appearance of the smart ring due to ring size adjustments. Moreover, the sliding connection between the first and second ends also facilitates stable and reciprocating deformation of the outer shell body, enabling reversible changes in its shape and thus facilitating reversible adjustments to the ring size.

[0009] In one possible implementation, the first end has a first sliding cavity, and the second end slides in contact with the inner wall of the first sliding cavity.

[0010] In this way, the first sliding cavity can restrict the relative movement between the first end and the second end, making the sliding connection between the first end and the second end more stable, which is conducive to the stable and reciprocating deformation of the outer shell body, and facilitates the reversible change of the shape of the outer shell body, thereby facilitating the reversible adjustment of the finger size of the smart ring.

[0011] In one possible implementation, the second end is inserted into the first sliding cavity, and the first end and the second end at least partially overlap, so that the outer shell body forms a closed annular structure.

[0012] In this way, the first and second ends at least partially overlap, making it easier to form a closed ring structure on the ring casing. This closed ring structure provides better stability to the ring casing and facilitates the sliding connection between the first and second ends. Furthermore, the second end is inserted into the first sliding cavity, which, while simplifying the formation of the closed ring structure, also ensures a stable sliding connection between the first and second ends. This facilitates stable and reciprocating deformation of the casing, allowing for reversible changes in its shape and thus enabling reversible adjustment of the smart ring's finger size.

[0013] In one possible implementation, the outer shell body further includes a main body segment, with a first end and a second end respectively connected to the two ends of the main body segment. Both the second end and the main body segment are sheet-like structures. The inner wall of the first sliding cavity includes an outer peripheral wall and an inner peripheral wall. The second end includes a first part and a second part. The first part slides in engagement with the outer peripheral wall of the first sliding cavity, and the second part slides in engagement with the inner peripheral wall of the first sliding cavity.

[0014] Both the outer and inner peripheral walls of the first sliding cavity extend circumferentially along the outer shell body, and are located on opposite radial sides of the first sliding cavity within the outer shell body. After the smart ring is worn on the user's finger, the inner peripheral wall of the first sliding cavity is located closer to the finger where the smart ring is located, while the outer peripheral wall is located further away from the finger where the smart ring is located.

[0015] This design facilitates easier deformation of the main body and second end of the sheet-like structure, allowing for greater deformation of the outer shell and increasing the adjustment range of the smart ring's finger size. Furthermore, the first part of the second end slides against the outer peripheral wall of the first sliding cavity, and the second part slides against the inner peripheral wall of the first sliding cavity. This ensures a relatively stable sliding connection between the second end of the sheet-like structure and the inner wall of the first sliding cavity. This allows for greater deformation of the outer shell, increasing the adjustment range of the smart ring's finger size, while simultaneously enabling stable and reciprocating deformation of the outer shell. This facilitates a significant degree of reversible change in the shape of the outer shell, thus enabling reversible adjustment of the smart ring's finger size over a wide range.

[0016] The main body, the first end, and the second end are an integral structure. The main body, the first end, and the second end are made of the same material, which is shape memory alloy.

[0017] In one possible implementation, the ring casing also includes a skateboard bridge. The first end and the second end are connected by the skateboard bridge, which has an arc-shaped structure. The main body of the ring and the skateboard bridge together form a closed ring structure. When the main body of the ring deforms, the first end can slide relative to the skateboard bridge along the extension direction of the skateboard bridge.

[0018] In this way, the ring casing can form a closed ring structure with the main body of the casing via the sliding bridge. This closed ring structure provides good structural stability for the ring casing. Furthermore, the first and second ends are connected by the sliding bridge, allowing for a sliding connection between the two ends while also enabling diverse aesthetic designs at both ends to meet the needs of smart ring appearance design. Additionally, connecting the first and second ends via a sliding bridge independent of the main body of the casing facilitates easier connection between the two ends.

[0019] In one possible implementation, the second end is fixedly connected to the skateboard bridge.

[0020] In this way, the skateboard bridge is more securely connected to the main body of the shell, and the skateboard bridge is not easy to fall off the main body of the shell, which is conducive to a more stable sliding connection between the first end and the second end through the skateboard bridge.

[0021] In one possible implementation, the second end is slidably connected to the skateboard bridge, and when the outer shell body deforms, the second end can slide relative to the skateboard bridge along the extension direction of the skateboard bridge.

[0022] In this way, both the first and second ends are slidably connected to the skateboard bridge, making it less likely for the skateboard bridge to get stuck or jammed when sliding between it and the main body of the outer shell. This also makes it easier for the main body of the outer shell to deform, which is beneficial for adjusting the ring size.

[0023] In one possible implementation, the second end has a second sliding cavity, and the slide bridge is inserted into the second sliding cavity and the first sliding cavity at the first end, with the slide bridge slidingly engaging with the inner wall of the second sliding cavity and the inner wall of the first sliding cavity.

[0024] In this way, the first and second sliding cavities can restrict the relative movement between the sliding bridge and the outer shell body. The sliding connection between the sliding bridge and the outer shell body is relatively stable, which is conducive to the stable and reciprocating deformation of the outer shell body and facilitates the reversible change of the shape of the outer shell body, thereby facilitating the reversible adjustment of the finger size of the smart ring.

[0025] In one possible implementation, the first end and the second end are spaced apart in the circumferential direction of the outer shell body, and a gap is formed between the first end and the second end in the outer shell body. The appearance of the smart ring can be formed by utilizing the gap between the first end and the second end in the outer shell body.

[0026] In some examples, the direction of the gap extends obliquely to the direction of the main body of the shell.

[0027] This makes it easier for the smart ring to achieve the desired appearance.

[0028] In some examples, the direction of the gap is perpendicular to the direction of the outer shell body.

[0029] This allows for a greater range of sliding between the first end and the skateboard bridge, as well as between the second end and the skateboard bridge, which in turn allows for greater deformation of the ring's outer shell, enabling the smart ring to adjust the finger size over a wider range.

[0030] In one possible implementation, the skateboard bridge is made of shape memory alloy.

[0031] In this way, by changing the temperature, the skateboard bridge can be transformed between the austenitic and martensitic phases, making it easier to adjust the shape of the skateboard bridge and maintain the adjusted shape more stably. By changing the shape of the skateboard bridge, it is easier to adjust the shape of the ring casing with the skateboard bridge, facilitating a greater degree of adjustment to the shape of the ring casing and maintaining the adjusted shape more stably. This allows for a wider range of adjustments to the ring's circumference and the maintenance of the adjusted circumference.

[0032] In other examples, the skateboard bridge can also be made of elastic or rigid materials.

[0033] In one possible implementation, at least one of the first end and the second end is provided with a limiting structure for limiting the range of relative sliding between the first end and the second end in the extension direction of the outer shell body.

[0034] In this way, the limiting structure can restrict the deformation of the outer shell, making it less likely to damage the smart ring due to excessive opening or contraction when the outer shell deforms. Furthermore, restricting the sliding of the first and second ends within a certain range helps maintain the ring-shaped structure of the ring shell, reducing the difficulty of reverse change due to excessive opening or contraction of the outer shell. This facilitates reversible changes in the shape of the outer shell, thereby enabling reversible adjustment of the ring's circumference.

[0035] In one possible implementation, the limiting structure includes a limiting groove and a protrusion. The protrusion passes through the limiting groove and is slidable along the extending direction of the outer shell body. The protrusion is used to abut against the end of the limiting groove to limit the range of relative sliding between the first end and the second end in the extending direction of the outer shell body.

[0036] In this way, by abutting the end of the protrusion and the limiting groove, it is easy to limit the relative sliding range of the first end and the second end in the extension direction of the outer shell body, and the limiting structure is relatively simple.

[0037] In one possible implementation, when the first end and the second end at least partially overlap: one of the first end and the second end has a protrusion, and the other of the first end and the second end has a limiting groove. This facilitates limiting the ring casing where the first end and the second end at least partially overlap.

[0038] In one possible implementation, when the ring casing includes a skateboard bridge and the first end and the second end are connected by the skateboard bridge: one of the first end and the skateboard bridge has a protrusion, and the other of the first end and the skateboard bridge has a limiting groove. This facilitates limiting the ring casing with the skateboard bridge.

[0039] In one possible implementation, when the second end is slidably connected to the skateboard bridge: the first end and the second end are provided with protrusions, the skateboard bridge is provided with a limiting groove, and the two ends of the limiting groove abut against the protrusions provided at the first end and the second end respectively, so as to limit the range of relative sliding between the first end and the second end in the extension direction of the outer shell body.

[0040] In this way, when both the first and second ends are slidably connected to the skateboard bridge, the first and second ends can be limited by the same limiting groove, making the structure of the first and second ends relatively simple and the forming of the limiting structure relatively easy.

[0041] In one possible implementation, the protrusion is an integral structure with the skateboard bridge of the outer shell or ring shell.

[0042] This reduces the number of parts and simplifies the structure of the ring case with protrusions, thus reducing the assembly steps between the protrusions and the main body of the case or the skateboard bridge.

[0043] In one possible implementation, the ring casing also includes a limiting member, which is fixedly connected to the casing body or the sliding bridge of the ring casing, and the limiting member includes a protrusion.

[0044] In this way, the formation of the protrusion is less restricted by the shape and material of the outer shell or the skateboard bridge, making it easier to form the protrusion. In addition, the protrusion can have high strength, which is conducive to a stable abutment between the protrusion and the end of the limiting groove.

[0045] A second aspect of this application provides a smart ring, which includes an electronic device and a ring casing as described in any of the above embodiments. The electronic device is disposed on the main body of the ring casing.

[0046] In one possible implementation, the smart ring also includes a soft rubber component, in which electronic devices are embedded. An assembly groove is formed on the inner side of the outer shell, and the soft rubber component is snapped into the assembly groove to house the electronic devices on the outer shell.

[0047] In this way, the soft rubber component is flexible, and its shape can change with the shape of the main body of the outer shell. The soft rubber component does not easily restrict the shape changes of the main body, allowing for adjustments to the ring's circumference while simultaneously ensuring a stable fit between the electronic components and the main body. Furthermore, multiple electronic components can be housed within the same soft rubber component, making the assembly of the smart ring more convenient. Additionally, the flexible nature of the soft rubber component allows for better contact with the user's fingers, enhancing the wearing comfort of the smart ring. Moreover, by securing the soft rubber component within the mounting slot to hold the electronic components within the main body, easy disassembly and reassembly between the soft rubber component and the main body facilitates maintenance and replacement of the electronic components.

[0077] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0078] This application provides a smart ring for wearing on the finger. In addition to its decorative function, the smart ring can also be used to realize one or more functions such as health management, sports monitoring, and communication.

[0079] Figure 1 This is a schematic diagram of a smart ring provided in an embodiment of this application.

[0080] like Figure 1 As shown, the smart ring includes a ring casing 10 and electronic components (not shown). The ring casing 10 has a ring-shaped structure and is used to limit the ring's circumference, allowing the smart ring to be worn securely on the user's finger. The electronic components are housed in the ring casing 10, which also serves to support them.

[0081] For example, the ring casing 10 has an assembly cavity, in which at least a portion of the electronic device can be disposed to facilitate assembly between the electronic device and the ring casing 10. With at least a portion of the electronic device disposed within the assembly cavity, the ring casing 10 also serves to protect the electronic device.

[0082] For example, the ring casing 10 includes an inner peripheral wall and an outer peripheral wall, both extending circumferentially along the ring casing 10. The inner and outer peripheral walls are located on opposite radial sides of the ring casing 10, and the mounting cavity is located between the inner and outer peripheral walls. After the smart ring is worn on the user's finger, the inner peripheral wall of the ring casing 10 is located on the side closer to the finger where the smart ring is located, and the outer peripheral wall is located on the side farther from the finger where the smart ring is located.

[0083] For example, the ring casing 10 is a closed ring structure, which makes the structure of the ring casing 10 more stable.

[0084] For example, a smart ring may include multiple electronic devices. These devices may include sensors, processors, batteries, communication devices, etc. The sensors, communication devices, and batteries may all be electrically connected to the processor. The battery may be used to power the sensors, processor, and communication devices. The processor may acquire signals detected by the sensors and process the acquired signals. The processor may communicate with other devices through the communication devices.

[0085] For example, a smart ring may include one or more sensors. For instance, a smart ring may include one or more of the following sensors: a photoplethysmography (PPG) sensor, a temperature sensor, a heart rate monitoring sensor, a gyroscope, an accelerometer, etc.

[0086] In some related technologies, the ring casing can be formed by stamping, stretching, and machining metal materials. The shape of the resulting casing is difficult to change, making it challenging to adjust the ring's finger size. Because the ring's size is difficult to adjust, it may become difficult to wear or loosen when the user's finger size changes. Furthermore, the limited adjustment makes it difficult for smart rings to accurately fit different finger sizes. This often necessitates manufacturing ring casings for different finger sizes, significantly increasing the difficulty of manufacturing, managing, and selling smart rings.

[0087] In some related technologies, the inner diameter of a smart ring can be adjusted by changing the shape of the inner wall of the ring's outer casing, thereby allowing for adjustment of the ring's finger size. However, in this method, the shape of the outer wall of the ring's outer casing often cannot be adjusted, meaning the outer diameter of the smart ring usually remains unchanged. When adjusting the finger size of the smart ring, its thickness changes accordingly. To ensure a secure fit on fingers with smaller finger sizes, the inner diameter of the smart ring needs to be reduced. This increases the ring's thickness, creating a larger gap between the finger wearing the smart ring and adjacent fingers. This results in a stronger feeling of pressure on adjacent fingers, leading to poor wearing comfort.

[0088] like Figure 1 As shown, based on this, in the embodiments of this application, the ring shell 10 includes a shell body 100, the shell body 100 is a ring structure, the shell body 100 is used to limit the finger circumference of the smart ring, the electronic device is disposed in the shell body 100, and the shell body 100 can play the role of carrying the electronic device.

[0089] For example, the housing body 100 has an assembly cavity, and after at least a portion of the electronic device is disposed in the assembly cavity, the housing body 100 can protect the electronic device.

[0090] For example, the outer casing 100 includes an inner peripheral wall and an outer peripheral wall, both extending circumferentially along the outer casing 100. The inner and outer peripheral walls are located on opposite radial sides of the outer casing 100. The inner peripheral wall of the outer casing 100 forms at least a portion of the inner peripheral wall of the ring casing 10, and the outer peripheral wall of the outer casing 100 forms at least a portion of the outer peripheral wall of the ring casing 10. That is, at least a portion of the inner peripheral wall of the ring casing 10 is the inner peripheral wall of the outer casing 100, and at least a portion of the outer peripheral wall of the ring casing 10 is the outer peripheral wall of the outer casing 100. An assembly cavity is located between the inner and outer peripheral walls of the outer casing 100.

[0091] After the smart ring is worn on the user's finger, the inner peripheral wall of the outer casing 100 is located on the side closer to the finger where the smart ring is located, and the outer peripheral wall of the outer casing 100 is located on the side farther away from the finger where the smart ring is located. The inner peripheral wall of the outer casing 100 is used to limit the inner diameter of the smart ring, and the outer peripheral wall of the outer casing 100 is used to limit the outer diameter of the smart ring.

[0092] Figure 2 for Figure 1 A cross-sectional schematic diagram of the smart ring provided in the image.

[0093] like Figure 2 As shown, and see Figure 1 In this embodiment, the outer shell body 100 includes a first end 110 and a second end 120, which are slidably connected. The outer shell body 100 is made of shape memory alloy. When the outer shell body 100 deforms, the first end 110 can slide relative to the second end 120 along the extending direction of the outer shell body 100.

[0094] Thus, the outer shell 100 is made of shape memory alloy, which allows it to transition between austenitic and martensitic phases by changing the temperature. Utilizing the elastic changes of the outer shell 100 in these phases, its shape can be easily adjusted and stably maintained. This enables adjustment of the smart ring's finger size and its maintenance. Consequently, the smart ring can be easily adjusted to fit different finger sizes and wear stably, meeting the needs of users with varying finger sizes and reducing the difficulty of manufacturing, managing, and selling smart rings.

[0095] Furthermore, the outer shell 100 is made of shape memory alloy, which facilitates the adjustment of the overall shape of the outer shell 100 (including the inner and outer peripheral walls of the outer shell 100) and the relatively stable maintenance of the adjusted shape. In other words, when adjusting the finger circumference of the smart ring, both the inner and outer diameters of the smart ring can be adjusted, which can reduce the change in thickness of the smart ring during the finger circumference adjustment process. This makes it less likely that the gap between the finger wearing the smart ring and the adjacent fingers will change significantly, and the squeezing sensation of the smart ring on the adjacent fingers will not change significantly after it is worn on the finger, which helps to improve the comfort of wearing the smart ring.

[0096] Furthermore, the first end 110 and the second end 120 are slidably connected, and the first end 110 can slide relative to the second end 120 along the extending direction of the outer shell body 100. This allows the ring size of the smart ring to be changed by deforming the outer shell body 100, while maintaining the ring-shaped form of the outer shell body 100, thus minimizing changes in the appearance of the smart ring caused by adjusting the ring size. Moreover, the slidable connection between the first end 110 and the second end 120 also facilitates stable and reciprocating deformation of the outer shell body 100, enabling reversible changes in the shape of the outer shell body 100, thereby facilitating reversible adjustment of the ring size.

[0097] In some examples, the outer shell body 100 can be made of a bidirectional shape memory alloy.

[0098] In some examples where the outer shell 100 is made of a bidirectional shape memory alloy, when the finger size of the smart ring needs to be adjusted, the temperature of the outer shell 100 can first be raised above its phase transition temperature. After the temperature of the outer shell 100 is higher than its phase transition temperature, the outer shell 100 can automatically open, making the finger size of the smart ring larger. After the finger size of the smart ring is larger, the smart ring can be placed on the user's finger or a reference post that matches the finger size of the user's finger. Then, the temperature of the outer shell 100 is lowered below its phase transition temperature. After the temperature of the outer shell 100 is lower than its phase transition temperature, the outer shell 100 can automatically shrink to fit the user's finger or the reference post, so as to adjust the finger size of the smart ring to fit the user's finger.

[0099] In other examples, the outer shell body 100 may be made of a unidirectional shape memory alloy.

[0100] In some examples where the outer shell 100 is made of unidirectional shape memory alloy, when the finger size of the smart ring needs to be adjusted, the temperature of the outer shell 100 can first be raised above its phase transition temperature. After the temperature of the outer shell 100 is higher than its phase transition temperature, the outer shell 100 can automatically open, making the finger size of the smart ring larger. After the finger size of the smart ring is larger, the smart ring can be placed on the user's finger or a reference post that matches the finger size of the user's finger. Then, the temperature of the outer shell 100 is lowered below its phase transition temperature. After the temperature of the outer shell 100 is lowered below its phase transition temperature, the outer shell 100 can be contracted under the action of external force to fit the user's finger or the reference post, so as to adjust the finger size of the smart ring to fit the user's finger.

[0101] In other examples where the outer shell 100 is made of a unidirectional shape memory alloy, when the finger size of the smart ring needs to be adjusted, the outer shell 100, whose temperature is lower than its phase transition temperature, can be opened under the action of external force, making the finger size of the smart ring larger. After the finger size of the smart ring is larger, it can be placed on the user's finger or a reference post that matches the finger size of the user's finger. Then, the temperature of the outer shell 100 is made higher than its phase transition temperature. After the temperature of the outer shell 100 is higher than its phase transition temperature, the outer shell 100 can automatically shrink to fit the user's finger or the reference post, so as to adjust the finger size of the smart ring to fit the user's finger.

[0102] For example, the phase transition temperature can be higher than room temperature, so that the outer shell 100 can maintain its shape relatively stably at room temperature, thereby making the ring size of the smart ring relatively stable at room temperature.

[0103] For example, shape memory alloys may include, but are not limited to, nickel-titanium alloys, copper-based alloys, titanium-based alloys, gold-based alloys, etc.

[0104] Figure 3 for Figure 1 An explosion diagram of the smart ring provided in the image.

[0105] like Figure 3 As shown, and see Figure 1 , Figure 2 In some possible implementations, the smart ring also includes a soft rubber component 20. Electronic devices are embedded within the soft rubber component 20. An assembly groove 310 is formed on the inner side of the outer casing 100, and the cavity of the assembly groove 310 forms an assembly cavity. The soft rubber component 20 is engaged within the assembly groove 310 to house the electronic devices within the outer casing 100.

[0106] Thus, the soft rubber component 20 is a flexible component, and its shape can change with the shape of the outer shell 100. The soft rubber component 20 does not easily restrict the shape changes of the outer shell 100, facilitating the adjustment of the smart ring's finger size while ensuring a relatively stable assembly of the electronic components to the outer shell 100. Furthermore, multiple electronic components can be mounted on the outer shell 100 using the same soft rubber component 20, making the assembly of the smart ring more convenient. Additionally, the flexible soft rubber component 20 can be used for contact with the user's fingers, improving the comfort of wearing the smart ring. Moreover, by securing the soft rubber component 20 within the mounting slot 310 to hold the electronic components in place, the soft rubber component 20 and the outer shell 100 can be easily detached, making maintenance and replacement of the electronic components easier and more convenient.

[0107] For example, electronic components can be encased within a soft rubber component 20, which can provide waterproofing for the encased electronic components, thereby improving the waterproof performance of the smart ring.

[0108] In other possible implementations, multiple electronic devices may be disposed on the housing body 100 by means of bonding or other methods, and the relative positions of different electronic devices may change when the housing body 100 is deformed.

[0109] Figure 4 for Figure 1 A cross-sectional schematic diagram of the ring casing of the smart ring provided in the image.

[0110] In some possible implementations, the first end 110 has a first sliding cavity 320, and the second end 120 slides in contact with the inner wall of the first sliding cavity 320.

[0111] In this way, the first sliding cavity 320 can restrict the relative movement between the first end 110 and the second end 120, making the sliding connection between the first end 110 and the second end 120 more stable, which is conducive to the stable and reciprocating deformation of the outer shell body 100, and facilitates the reversible change of the shape of the outer shell body 100, thereby facilitating the reversible adjustment of the finger circumference of the smart ring.

[0112] In some possible implementations, the first end 110 and the second end 120 at least partially overlap so that the housing body 100 forms a closed annular structure.

[0113] In this way, it is relatively simple to form a closed ring structure for the ring shell 10. The closed ring structure can make the structure of the ring shell 10 more stable and also facilitate the sliding connection between the first end 110 and the second end 120.

[0114] In some examples where the first end 110 and the second end 120 at least partially overlap, the second end 120 is inserted into the first sliding cavity 320 and slides against the inner wall of the first sliding cavity 320.

[0115] In this way, the closed ring structure of the ring shell 10 is relatively simple and facilitates the sliding connection between the first end 110 and the second end 120. At the same time, the sliding connection between the first end 110 and the second end 120 is relatively stable, which is conducive to the stable and reciprocating deformation of the shell body 100, and facilitates the reversible change of the shape of the shell body 100, thereby facilitating the reversible adjustment of the finger size of the smart ring.

[0116] In some other examples where the first end 110 and the second end 120 at least partially overlap, one of the first end 110 and the second end 120 may overlap the outside of the other of the first end 110 and the second end 120, so that the housing body 100 forms a closed ring structure.

[0117] Figure 5 for Figure 1 Another cross-sectional schematic diagram of the smart ring provided in the image.

[0118] like Figure 5 As shown, and see Figure 4 In some possible implementations, at least one of the first end 110 and the second end 120 is provided with a limiting structure 200, which limits the range of relative sliding between the first end 110 and the second end 120 in the extending direction of the housing body 100.

[0119] In this way, the limiting structure 200 can restrict the deformation of the outer shell 100, so that when the outer shell 100 deforms, it is not easy to damage the smart ring due to excessive opening or contraction. In addition, restricting the sliding of the first end 110 and the second end 120 within a certain range helps to keep the ring shell 10 in a ring-shaped structure, making it less likely that the outer shell 100 will have difficulty changing in reverse due to excessive opening or contraction. This facilitates the reversible change of the shape of the outer shell 100, and thus makes it easier to realize the reversible adjustment of the ring's finger size.

[0120] In some possible implementations, the limiting structure 200 includes a limiting groove 210 and a protrusion 220. The protrusion 220 passes through the limiting groove 210 and can slide along the extension direction of the outer shell body 100. The protrusion 220 is used to abut against the end of the limiting groove 210 to limit the range of relative sliding between the first end 110 and the second end 120 in the extension direction of the outer shell body 100.

[0121] In this way, by abutting the end of the protrusion 220 against the limiting groove 210, it is easy to limit the range of relative sliding of the first end 110 and the second end 120 in the extending direction of the outer shell body 100, and the limiting structure 200 is relatively simple.

[0122] The two ends of the limiting groove 210 extend along the extension direction of the outer shell body 100.

[0123] For example, the limiting structure 200 includes multiple limiting grooves 210 spaced apart along the width direction of the smart ring, and multiple protrusions 220 corresponding to the limiting grooves 210. The protrusions 220 pass through the corresponding limiting grooves 210 and abut against the ends of the corresponding limiting grooves 210. By having multiple protrusions 220 abut against the ends of the corresponding limiting grooves 210, the limiting effect can be improved. For example, the limiting structure 200 includes two limiting grooves 210 spaced apart along the width direction of the smart ring.

[0124] For example, multiple limiting grooves 210 can be arranged side by side, and multiple protrusions 220 can be arranged in rows along the arrangement direction of the multiple limiting grooves 210.

[0125] In some examples where the first end 110 and the second end 120 at least partially overlap, one of the first end 110 and the second end 120 is provided with a limiting groove 210, and the other of the first end 110 and the second end 120 is provided with a protrusion 220.

[0126] This facilitates the positioning of the ring casing 10, where the first end 110 and the second end 120 at least partially overlap.

[0127] In some examples where the second end 120 is inserted into the first sliding cavity 320, the first end 110 is provided with a protrusion 220 and the second end 120 is provided with a limiting groove 210, so that the groove wall of the protrusion 220 and the limiting groove 210 is less likely to come into contact with the user's finger or the reference post used when adjusting the finger size, which facilitates the smooth sliding of the protrusion 220 in the limiting groove 210 and also helps to improve the comfort of wearing the smart ring.

[0128] For example, the protrusion 220 is located within the first sliding cavity 320, so that the protrusion 220 has little impact on the comfort of wearing the smart ring.

[0129] In some examples where the first end 110 and the second end 120 at least partially overlap, the protrusion 220 is an integral structure with the outer shell body 100.

[0130] In this way, when the first end 110 and the second end 120 overlap at least partially, the ring case 10 with the protrusion 220 has fewer parts and a simpler structure, which can reduce the assembly steps between the protrusion 220 and the case body 100.

[0131] When the protrusion 220 and the outer shell body 100 are integrally structured, the material of the protrusion 220 is the same as that of the outer shell body 100. The protrusion 220 can have a certain degree of elasticity so that the second end 120 can be inserted into the first sliding cavity 320.

[0132] In some examples where the protrusion 220 is an integral part of the outer shell body 100, the protrusion 220 can be a flanged structure, that is, the protrusion 220 can be a partial flanged structure of the outer shell body 100.

[0133] Figure 6 This is a cross-sectional schematic diagram of yet another smart ring provided in an embodiment of this application. Figure 7 for Figure 6 A cross-sectional schematic diagram of the ring casing of the smart ring provided in the image.

[0134] like Figure 6 , Figure 7 As shown, in some examples where the protrusion 220 and the outer shell body 100 are integrally formed, the protrusion 220 can be an arched structure, which can arch towards the first sliding cavity 320. The arched structure can be formed by local stamping of the outer shell body 100.

[0135] Figure 8 This is a schematic diagram of yet another smart ring provided in an embodiment of this application. Figure 9 for Figure 8 The diagram showing the explosion of the smart ring provided in the image. Figure 10 for Figure 8 A cross-sectional schematic diagram of the ring casing of the smart ring provided in the image.

[0136] like Figures 8-10 As shown, in some possible embodiments, the outer shell body 100 further includes a body segment 130, with a first end 110 and a second end 120 respectively connected to the two ends of the body segment 130, and both the second end 120 and the body segment 130 are sheet-like structures.

[0137] In this way, the main body segment 130 and the second end 120 of the sheet-like structure are easier to deform, which is conducive to the large-scale deformation of the outer shell body 100 and to increasing the adjustment range of the finger circumference of the smart ring.

[0138] For example, the first end 110, the second end 120 and the main body segment 130 are an integral structure, and the first end 110, the second end 120 and the main body segment 130 are made of the same material, which is shape memory alloy.

[0139] In some examples where the outer shell body 100 includes a main body segment 130 and a second end 120 with a sheet-like structure, the inner wall of the first sliding cavity 320 includes an outer peripheral wall 322 and an inner peripheral wall 321, and the second end 120 includes a first part 121 and a second part 122. The first part 121 is slidably engaged with the outer peripheral wall 322 of the first sliding cavity 320, and the second part 122 is slidably engaged with the inner peripheral wall 321 of the first sliding cavity 320.

[0140] This facilitates a relatively stable sliding connection between the second end 120 of the sheet-like structure and the inner wall of the first sliding cavity 320. This allows for a greater degree of deformation of the outer shell body 100 and an increase in the adjustment range of the smart ring's finger size. Simultaneously, it enables stable and reciprocating deformation of the outer shell body 100, allowing for a greater degree of reversible change in the shape of the outer shell body 100. This, in turn, facilitates reversible adjustment of the smart ring's finger size within a wider range.

[0141] Both the outer peripheral wall 322 and the inner peripheral wall 321 of the first sliding cavity 320 extend circumferentially along the outer shell body 100. The outer peripheral wall 322 and the inner peripheral wall 321 of the first sliding cavity 320 are located on opposite sides of the first sliding cavity 320 in the radial direction of the outer shell body 100. After the smart ring is worn on the user's finger, the inner peripheral wall 321 of the first sliding cavity 320 is located on the side closer to the finger where the smart ring is located, and the outer peripheral wall 322 of the first sliding cavity 320 is located on the side farther away from the finger where the smart ring is located.

[0142] For example, the second end 120 also includes a third part 123, which is located between the first part 121 and the second part 122. The first part 121 is connected to the main body segment 130, and the first part 121 is connected to the second part 122 through the third part 123. The two ends of the third part 123 are spaced apart in the radial direction of the outer shell body 100.

[0143] The first part 121, the second part 122, the third part 123, the main body segment 130, and the first end 110 are an integral structure. The first part 121, the second part 122, the third part 123, the main body segment 130, and the first end 110 are all made of the same material, which is shape memory alloy. The first part 121, the second part 122, and the third part 123 can be formed by bending the second end 120.

[0144] In some examples where the second end 120 includes a first part 121 and a second part 122, the limiting structure 200 may be located at the second part 122. For example, the limiting groove 210 may be located at the second part 122. In this case, the limiting structure 200 is located close to the end face of the second end 120, which can improve the stability of the sliding connection between the first end 110 and the second end 120.

[0145] The two ends of the soft rubber component 20 can be respectively inserted into the two ends of the first sliding cavity 320. Specifically, one end of the soft rubber component 20 is inserted between the first part 121, the third part 123 and the inner peripheral wall 321 of the first sliding cavity 320, and the other end of the soft rubber component 20 is inserted between the inner peripheral wall 321 and the outer peripheral wall 322 of the first sliding cavity 320, and is located on the side of the second part 122 away from the first part 121. At this time, the first part 121, the outer peripheral wall 322 of the first sliding cavity 320 and the inner peripheral wall 321 of the first sliding cavity 320 can be used to form an assembly cavity.

[0146] Figure 11 for Figure 8 A cross-sectional schematic diagram of the smart ring provided in the image. Figure 12 for Figure 8 Another cross-sectional schematic diagram of the smart ring provided in the image.

[0147] like Figure 11 , Figure 12 As shown, in some possible embodiments, the ring casing 10 further includes a limiting member 400, which includes a protrusion 220 and is used to abut against the end of the limiting groove 210 to limit the range of relative sliding between the first end 110 and the second end 120 in the extending direction of the casing body 100.

[0148] In this way, the formation of the protrusion 220 is less restricted by the shape and material of the outer shell body 100, making it easier to form the protrusion 220. In addition, the protrusion 220 can have high strength, which is conducive to the stable contact between the protrusion 220 and the end of the limiting groove 210.

[0149] In some examples where the first end 110 and the second end 120 at least partially overlap, the limiting member 400 is fixedly connected to the housing body 100. Specifically, the limiting member 400 is fixedly connected to one of the first end 110 and the second end 120, and the other of the first end 110 and the second end 120 is provided with a limiting groove 210.

[0150] In some examples where the second end 120 is inserted into the first sliding cavity 320, the limiting member 400 can be fixedly connected to the first end 110, the second end 120 is provided with a limiting groove 210, and the protrusion 220 is located in the first sliding cavity 320, so that the protrusion 220 and the groove wall of the limiting groove 210 are less likely to come into contact with the user's finger or the reference post used when adjusting the finger size, which is conducive to the smooth sliding of the protrusion 220 in the limiting groove 210, and also helps to improve the comfort of wearing the smart ring.

[0151] For example, the limiting member 400 can be a rivet.

[0152] In some examples where the second end 120 includes a first part 121 and a second part 122, the limiting groove 210 may be provided in the second part 122 and extend through both sides of the second part 122 in the thickness direction. The limiting member 400 is located in the second part 122, and part of the limiting member 400 is located on the side of the second part 122 away from the inner peripheral wall 321 of the first sliding cavity 320.

[0153] Figure 13 This is a schematic diagram of yet another smart ring provided in an embodiment of this application. Figure 14 for Figure 13 The provided diagram shows the explosion of the smart ring. Figure 15 for Figure 13 A cross-sectional schematic diagram of the provided smart ring. Figure 16 for Figure 13 A cross-sectional schematic diagram of the ring casing of the provided smart ring.

[0154] like Figures 13-16 As shown, in some possible embodiments, the ring casing 10 further includes a sliding bridge 500, with the first end 110 and the second end 120 connected by the sliding bridge 500. The sliding bridge 500 has an arc-shaped structure, and the casing body 100 and the sliding bridge 500 together form a closed ring structure. When the casing body 100 deforms, the first end 110 can slide relative to the sliding bridge 500 along the extending direction of the sliding bridge 500.

[0155] In this way, the ring shell 10 can form a closed ring structure with the shell body 100 via the sliding bridge 500. This closed ring structure provides good structural stability for the ring shell 10. Furthermore, the first end 110 and the second end 120 are connected by the sliding bridge 500, allowing for a sliding connection between them while also enabling diverse aesthetic designs at both ends to meet the needs of smart ring appearance design. Additionally, connecting the first end 110 and the second end 120 via the sliding bridge 500, which is independent of the shell body 100, facilitates easier connection between the two ends.

[0156] The first end 110 is slidably connected to the skateboard bridge 500, so that the first end 110 is slidably connected to the second end 120 through the skateboard bridge 500.

[0157] In the example where the second end 120 slides into the inner wall of the first sliding cavity 320, the slide bridge 500 is inserted into the first sliding cavity 320 and slides into the inner wall of the first sliding cavity 320. The second end 120 slides into the inner wall of the first sliding cavity 320 through the slide bridge 500. The first sliding cavity 320 can restrict the relative movement between the first end 110 and the slide bridge 500, thereby restricting the relative movement between the first end 110 and the second end 120.

[0158] In some possible implementations, the second end 120 is fixedly connected to the skateboard bridge 500.

[0159] In this way, the skateboard bridge 500 is more securely connected to the outer shell 100, and the skateboard bridge 500 is less likely to fall off the outer shell 100, which facilitates a more stable sliding connection between the first end 110 and the second end 120 through the skateboard bridge 500.

[0160] For example, the second end 120 can be fixedly connected to the slide bridge 500 by a fastener 600. For example, the fastener 600 can be a threaded fastener.

[0161] For example, the second end 120 may have a fixed cavity, and one end of the slide bridge 500 is inserted into the fixed cavity and fixedly connected to the second end 120.

[0162] In some possible implementations, the skateboard bridge 500 is made of shape memory alloy.

[0163] In this way, by changing the temperature, the skateboard bridge 500 can be transformed between the austenitic and martensitic phases, making it easier to adjust the shape of the skateboard bridge 500 and maintain its adjusted shape more stably. By changing the shape of the skateboard bridge 500, it is easier to adjust the shape of the ring shell 10 with the skateboard bridge 500, facilitating a greater degree of adjustment to the shape of the ring shell 10 and maintaining its adjusted shape more stably. This allows for a wider range of adjustments to the ring's circumference and the maintenance of the adjusted circumference.

[0164] For example, the material of the skateboard bridge 500 can be the same as or different from the material of the outer shell body 100.

[0165] In other possible implementations, the skateboard bridge 500 may also be made of an elastic or rigid material.

[0166] In some examples where the ring casing 10 includes a skateboard bridge 500, a first end 110 and a second end 120 connected by the skateboard bridge 500, one of the first end 110 and the skateboard bridge 500 is provided with a protrusion 220, and the other of the first end 110 and the skateboard bridge 500 is provided with a limiting groove 210.

[0167] This facilitates the limiting of the ring casing 10 with the skateboard bridge 500.

[0168] In some examples, the first end 110 has a limiting groove 210, and the slide bridge 500 has a protrusion 220.

[0169] In some examples where the ring casing 10 includes a skateboard bridge 500 and a first end 110 and a second end 120 connected by the skateboard bridge 500, the limiting member 400 is fixedly connected to the casing body 100 or the skateboard bridge 500 of the ring casing 10. Specifically, the limiting member 400 is fixedly connected to one of the first end 110 and the skateboard bridge 500, and the other of the first end 110 and the skateboard bridge 500 is provided with a limiting groove 210.

[0170] In some examples, the first end 110 has a limiting groove 210, and the skateboard bridge 500 is fixedly connected to a limiting member 400. For example, the limiting member 400 can be a stud, the limiting member 400 can be threaded to the skateboard bridge 500, and the head of the limiting member 400 can be located in the limiting groove 210.

[0171] For example, the limiting member 400 and the fastener 600 can be respectively provided at both ends of the slide bridge 500.

[0172] Figure 17 This is a schematic diagram of yet another smart ring provided in an embodiment of this application. Figure 18 for Figure 17 The provided diagram shows the explosion of the smart ring. Figure 19 for Figure 17 A cross-sectional schematic diagram of the provided smart ring.

[0173] In some possible implementations, the second end 120 is slidably connected to the skateboard bridge 500, and when the outer shell body 100 deforms, the second end 120 can slide relative to the skateboard bridge 500 along the extension direction of the skateboard bridge 500.

[0174] In this way, both the first end 110 and the second end 120 are slidably connected to the skateboard bridge 500. The sliding between the skateboard bridge 500 and the outer shell body 100 is less likely to cause problems such as jamming. The sliding between the skateboard bridge 500 and the outer shell body 100 is relatively easy, making it easier for the outer shell body 100 to deform, which is beneficial for adjusting the finger size of the smart ring.

[0175] In some examples where the second end 120 is slidably connected to the skateboard bridge 500, the second end 120 has a second sliding cavity 330, the skateboard bridge 500 is inserted into the second sliding cavity 330 and the first sliding cavity 320 of the first end 110, and the skateboard bridge 500 slides in cooperation with the inner wall of the second sliding cavity 330 and the inner wall of the first sliding cavity 320.

[0176] In this way, the first sliding cavity 320 and the second sliding cavity 330 can restrict the relative movement between the sliding bridge 500 and the outer shell body 100. The sliding connection between the sliding bridge 500 and the outer shell body 100 is relatively stable, which is conducive to the stable and reciprocating deformation of the outer shell body 100, and facilitates the reversible change of the shape of the outer shell body 100, thereby facilitating the reversible adjustment of the finger circumference of the smart ring.

[0177] In some examples where the second end 120 is slidably connected to the skateboard bridge 500, the first end 110 and the second end 120 are provided with protrusions 220, and the skateboard bridge 500 is provided with a limiting groove 210. The two ends of the limiting groove 210 abut against the protrusions 220 provided at the first end 110 and the second end 120 respectively, so as to limit the range of relative sliding between the first end 110 and the second end 120 in the extending direction of the outer shell body 100.

[0178] In this way, when both the first end 110 and the second end 120 are slidably connected to the skateboard bridge 500, the first end 110 and the second end 120 can be limited by the same limiting groove 210, making the structure of the first end 110 and the second end 120 relatively simple and the forming of the limiting structure 200 relatively easy.

[0179] For example, the skateboard bridge 500 is provided with multiple limiting grooves 210, the first end 110 is provided with multiple protrusions 220 corresponding to the limiting grooves 210, and the second end 120 is provided with multiple protrusions 220 corresponding to the limiting grooves 210. The protrusions 220 of the first end 110 and the second end 120 pass through the corresponding limiting grooves 210.

[0180] In some examples where the ring casing 10 includes a skateboard bridge 500 and a first end 110 and a second end 120 connected by the skateboard bridge 500, the protrusion 220 is an integral structure with the casing body 100 or the skateboard bridge 500 of the ring casing 10.

[0181] In this way, when the ring casing 10 includes the skateboard bridge 500 and the first end 110 and the second end 120 are connected by the skateboard bridge 500, the structure of the ring casing 10 with the protrusion 220 can be simplified, and the assembly steps between the protrusion 220 and the casing body 100 or the skateboard bridge 500 can be reduced.

[0182] For example, the protrusion 220 can be formed by partial stamping of the housing body 100 or the slide bridge 500.

[0183] In some possible implementations, the first end 110 and the second end 120 are spaced apart in the circumferential direction of the housing body 100, and the housing body 100 forms a gap 340 between the first end 110 and the second end 120.

[0184] In some examples, the extension direction of the gap 340 formed between the first end 110 and the second end 120 of the outer shell body 100 is oblique to the extension direction of the outer shell body 100. That is, the extension direction of the gap 340 formed between the first end 110 and the second end 120 of the outer shell body 100 is inclined to the axial direction of the outer shell body 100, so that the smart ring can form a set appearance shape.

[0185] Figure 20 This is a schematic diagram of yet another smart ring provided in an embodiment of this application. Figure 21 for Figure 20 A cross-sectional schematic diagram of the provided smart ring.

[0186] In some possible implementations, the extension direction of the gap 340 formed between the first end 110 and the second end 120 of the housing body 100 is perpendicular to the extension direction of the housing body 100.

[0187] This facilitates a wider range of sliding between the first end 110 and the skateboard bridge 500, as well as between the second end 120 and the skateboard bridge 500, thereby allowing the ring casing 10 to deform to a greater extent, enabling the smart ring to adjust the finger circumference within a wider range.

[0188] For example, the smart ring may also include a decorative element 30, which may be disposed on the outer peripheral wall of the housing body 100 to achieve diverse appearance effects of the smart ring.
