Description

Technical Field

[0001] This application relates to the field of wearable device technology, and more particularly to a wearable device and electronic system. Background Technology

[0002] With the continuous development of information technology, microelectronics technology, and new materials processes, wearable devices such as smart rings and smart bracelets have gradually entered the consumer market, enriching users' choices. These wearable devices combine decorative attributes with portability, allowing them to seamlessly integrate into users' daily lives. They also offer functions such as health monitoring and information reminders, possessing high practical value and gradually gaining popularity among consumers.

[0003] However, the development of wearable devices still faces a key bottleneck: size adjustment. Due to significant differences in the size of the wearing area among different users, consumers often need to go through a cumbersome measurement process to determine the appropriate model when purchasing wearable devices, greatly impacting the buying experience. Therefore, designing a wearable device that allows for flexible size adjustment has become one of the important issues in the industry. Utility Model Content

[0004] Embodiments of this application provide a wearable device and electronic system to solve the problem of insufficient space for electronic components in wearable devices in related technologies.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, embodiments of this application provide a wearing device, including a wearing ring, an adjustment structure, and electronic components. The wearing ring is used to be fitted onto a wearing area, the wearing ring is broken in its circumferential direction, and the wearing ring has a first overlapping segment and a second overlapping segment at the break point. The first overlapping segment and the second overlapping segment overlap in the circumferential direction of the wearing ring, and the first overlapping segment and the second overlapping segment are arranged along the axial direction of the wearing ring. The wearing ring has a first receiving cavity, the first receiving cavity extends in the circumferential direction of the wearing ring, one end of the first receiving cavity extends into the first overlapping segment, and the other end of the first receiving cavity extends into the second overlapping segment. The electronic components are disposed in the first receiving cavity. The adjustment structure connects the first overlapping segment and the second overlapping segment, so that the overlap length of the first overlapping segment and the second overlapping segment in the circumferential direction of the wearing ring is adjustable, thereby making the size of the central opening of the wearing ring adjustable.

[0007] In the wearing device of this embodiment, since the first overlapping segment and the second overlapping segment overlap in the circumferential direction, one end of the first receiving cavity extends into the first overlapping segment, and the other end of the first receiving cavity extends into the second overlapping segment. That is, in addition to having a first receiving cavity along the entire circumference of the wearing ring, the overlapping segment of the wearing ring also has an additional first receiving cavity. This greatly increases the space of the first receiving cavity, which not only facilitates the arrangement of more electronic components within the wearing ring to expand the functionality of the wearing device, but also allows the electronic components to be arranged at different positions along the circumference of the wearing ring according to actual functional needs, thus facilitating optimized layout of the electronic components. Furthermore, since the first overlapping segment and the second overlapping segment are arranged along the axial direction of the wearing ring, this avoids the overlapping segment compressing the space of the central ring opening, thereby preventing interference between the overlapping segment and the wearing part that could affect the user's wearing comfort.

[0008] In some embodiments of the first aspect, the adjustment structure includes a first slot and a second receiving cavity disposed in the first overlapping section, a locking member disposed in the second receiving cavity, and a first pin disposed in the second overlapping section; the first slot extends circumferentially along the wearing ring body and communicates with the second receiving cavity; the locking member has a plurality of locking portions arranged circumferentially along the wearing ring body; the first pin extends into the second receiving cavity from the first slot; the first pin can be connected to and separated from the locking portions; when the first pin is connected to the locking portion, the locking member prevents the first pin from moving along the first slot to prevent the overlap length from changing; when the first pin is separated from the locking portion, the first pin can move along the first slot to allow the overlap length to change. This configuration allows for multi-level adjustment of the size (e.g., diameter) of the central opening of the wearing ring body; and when the first pin is connected to a locking portion, the wearing ring body exerts no clamping force on the user's wearing area, thereby increasing the comfort of the wearing device.

[0009] In some embodiments of the first aspect, the locking element is a rack with multiple ratchet teeth arranged circumferentially along the wearing ring body. Each ratchet tooth has a stop tooth surface and a guide tooth surface. The guide tooth surface is located on the side of the stop tooth surface near the end of the first overlapping section and is inclined relative to the stop tooth surface. The locking portion is a groove between two adjacent ratchet teeth, into which the end of the first pin extends. The wearing ring body is elastic. When the first pin moves out of the locking portion, under the action of the wearing ring body's own elasticity, the second overlapping section can drive the first pin to move towards the end of the first slot near the end of the first overlapping section, thereby reducing the overlapping length. With this configuration, when adjusting the size of the central opening of the wearing ring body, it is not necessary to manually move the first pin out of the locking portion, thus simplifying the user's operation. Furthermore, when the first pin moves out of the locking portion and the size of the central opening is adjusted, it can prevent the wearing ring body from generating a large clamping force on the wearing part, thereby making the wearing device more comfortable.

[0010] In some embodiments of the first aspect, the end of the first pin is provided with a pin bevel, the pin bevel being inclined relative to the length direction of the first pin, and the pin bevel being used to contact the guide tooth surface. This arrangement allows the first pin to engage more securely with the locking part.

[0011] In some embodiments of the first aspect, the second overlapping section is provided with a pin receiving groove, the pin receiving groove extending axially along the wearing ring body, a portion of the first pin slidingly engaging with the pin receiving groove, and another portion of the first pin extending from the first slot into the second receiving cavity; the adjustment structure further includes an elastic element disposed in the pin receiving groove, the elastic element being connected between the groove wall of the pin receiving groove and the first pin, and used to apply an elastic force to the first pin, the elastic force being used to move the first pin toward the locking member. With this configuration, the pin receiving groove can guide the first pin, preventing the first pin from deflecting during movement, thereby ensuring accurate connection and separation of the first pin with the locking part; by providing the elastic element, there is no need to manually adjust the position of the first pin and its connection with the locking part, thus simplifying the user's operation.

[0012] In some embodiments of the first aspect, the pin receiving groove has a slot on one side near the central opening of the wearing ring body, and a cover plate is provided at the slot, the cover plate covering a portion of the slot, and the other portion of the slot forming a clearance opening. A toggle part is fixedly provided on the first pin, and the toggle part extends from the clearance opening beyond the second overlapping section. This arrangement facilitates user operation of the first pin.

[0013] In some embodiments of the first aspect, the adjustment structure includes a first slot disposed in the first overlapping section and a first pin disposed in the second overlapping section. The first slot extends circumferentially along the wearing ring body, and the first pin extends into the first slot. The wearing ring body is a reverse characteristic shape memory alloy. When the temperature of the wearing ring body is higher than the phase transition temperature of its material, the wearing ring body can deform, allowing the first pin to move along the first slot, thereby making the overlap length adjustable. When the temperature of the wearing ring body is lower than the phase transition temperature of its material, the position of the first pin relative to the first slot is fixed, and the overlap length is fixed. This configuration enables stepless adjustment of the size of the central loop of the wearing ring body, allowing for better matching with the size of different users' wearing parts.

[0014] In some embodiments of the first aspect, the adjusting structure further includes a second receiving cavity disposed in the first overlapping section, the first slot communicating with the second receiving cavity, and the first pin extending from the first slot into the second receiving cavity; the first pin is provided with a first limiting portion located in the second receiving cavity and capable of stopping at the edge of the first slot to prevent the first pin from moving out of the first slot. With this configuration, the first limiting portion can axially limit the first pin, preventing the first pin from moving out of the first slot.

[0015] In some embodiments of the first aspect, the adjustment structure further includes a second slot disposed in the second overlapping segment and a second pin disposed in the first overlapping segment; the second slot extends circumferentially along the wearing ring body, and the second pin slides into the second slot; when the overlap length is at its maximum value, the first slot and the second slot are staggered circumferentially along the wearing ring body, and the first pin is located at the end of the first slot away from the end of the first overlapping segment, and the second pin is located at the end of the second slot away from the end of the second overlapping segment. This arrangement can suppress the end of the overlapping segment of the wearing ring body from warping due to stress, thus preventing it from affecting the shape of the wearing ring body.

[0016] In some embodiments of the first aspect, one end of the first slot extends to the end of the first overlapping segment, and one end of the second slot extends to the end of the second overlapping segment. This arrangement better prevents the end of the overlapping segment of the wearing ring from warping due to stress, thus affecting the shape of the wearing ring.

[0017] In some embodiments of the first aspect, the adjusting structure further includes a third receiving cavity disposed in the second overlapping section, the second slot communicating with the third receiving cavity, and the second pin extending from the second slot into the third receiving cavity; the second pin is provided with a second limiting portion located in the third receiving cavity and used to stop at the edge of the second slot to prevent the second pin from moving out of the second slot. With this configuration, the second limiting portion can axially limit the second pin, preventing the second pin from moving out of the second slot.

[0018] In some embodiments of the first aspect, the wearing ring includes a first semi-ring segment and a second semi-ring segment connected to each other. The first semi-ring segment includes a first overlapping segment, and the second semi-ring segment includes a second overlapping segment. The first semi-ring segment extends along a spatial curve, and the second semi-ring segment extends along a planar curve. The electronic device includes a battery and a flexible circuit board electrically connected to the battery. The battery is located in a first receiving cavity within the second semi-ring segment, and the flexible circuit board is located in the first receiving cavity within the first semi-ring segment. This arrangement allows for an optimized layout of the electronic device within the first receiving cavity of the wearing ring.

[0019] In some embodiments of the first aspect, the wearing ring body is a metal or alloy part, and the first overlapping segment and the second overlapping segment have surface treatment areas on the side surface away from the central opening of the wearing ring body, respectively. The surface treatment areas include a polishing area, a sandblasting area, and a brushing area arranged circumferentially along the wearing ring body, with the sandblasting area disposed between the polishing area and the brushing area. This arrangement can improve the recognizability of the wearing device.

[0020] Secondly, embodiments of this application provide an electronic system including a charging dock and a wearable device as described in any of the embodiments of the first aspect, wherein the charging dock is used to charge the wearable device.

[0021] The beneficial effects of the electronic system in this application embodiment are the same as those of the wearable device in the first aspect, and will not be repeated here.

[0022] Thirdly, embodiments of this application provide an electronic system including a charging base and a wearable device as described in some embodiments of the first aspect. The charging base has a charging area for mounting the wearable device, and the charging area has a heating element for heating the wearing loop of the wearable device.

[0023] The beneficial effects of the electronic system in this application embodiment are the same as those of the wearable device in the first aspect, and will not be repeated here. Attached Figure Description

[0043] With the continuous development of information technology, microelectronics technology, and new materials processes, wearable devices such as smart rings and smart bracelets have gradually entered the consumer market, enriching users' choices. These wearable devices combine decorative attributes with portability, allowing them to seamlessly integrate into users' daily lives. They also offer functions such as health monitoring and information reminders, possessing high practical value and gradually gaining popularity among consumers.

[0044] However, the development of wearable devices still faces a key bottleneck: size adjustment. Due to significant differences in the size of the wearing area among different users, consumers often need to go through a cumbersome measurement process to determine the appropriate model when purchasing wearable devices, greatly impacting the purchasing experience. On the other hand, to meet the needs of different users, manufacturers need to launch multiple size models for the same product. This not only increases the complexity of mold design and parts management in the production process but also raises operating costs in warehousing and transportation, hindering the large-scale production and market promotion of wearable devices.

[0045] Therefore, designing a wearable device that can be flexibly adjusted in size is of great significance for simplifying the user's purchasing process, improving the purchasing experience, and reducing production and operating costs. It is a key direction for promoting the further development and popularization of wearable device technology.

[0046] Figure 1 This is a structural diagram of a wearable device (smart ring) in related technologies. Figure 1As shown, the wearable device includes a device head 01, and a first flexible band 02 and a second flexible band 03 respectively connected to opposite sides of the device head 01. The device head 01 is used to house electronic devices such as batteries and functional components. The end of the first flexible band 02 is provided with a buckle 021, which protrudes from the surface of the first flexible band 02. The second flexible band 03 is provided with a plurality of spaced holes 031, and the end of the second flexible band 03 is provided with a strap frame 04.

[0047] When worn, the end of the first flexible band 02 passes through the strap frame 04, and the buckle 021 engages with the strap hole 031, so that the device head 01, the first flexible band 02, and the second flexible band 03 form a wearing ring structure, which is fitted onto the wearing area. The size of the wearing device can be adjusted by engaging the buckle 021 with different strap holes 031.

[0048] However, the electronic components of the wearable device can only be housed in the head 01 of the device, while other positions in the circumferential direction of the wearable device, such as the first flexible band 02 and the second flexible band 03, cannot accommodate the electronic components. This results in a relatively small and concentrated storage space for the wearable device, which not only limits the number of electronic components that can be installed, which is not conducive to the expansion of the wearable device's functions, but also makes it difficult to optimize the layout of the electronic components by concentrating them in the head 01 of the device.

[0049] Therefore, this application provides a wearable device and electronic system. The wearable device features a circumferentially broken wearing ring with two overlapping ends. These two ends are arranged axially along the wearing ring and connected by an adjustment structure. The adjustment structure allows for adjustment of the overlap length between the two ends of the wearing ring, thus adjusting the size of the wearable device. Furthermore, the electronic components of the wearable device can be arranged circumferentially along the wearing ring, which not only facilitates the expansion of the device's functionality but also allows for optimized layout of the electronic components.

[0050] The wearable device in this application embodiment can be, but is not limited to, a smart bracelet, a smart ring, a smart headband, or other ring-shaped wearable device. The wearable device in this application embodiment is described below using a smart ring as an example. Other types of wearable devices can be set up by referring to the structure in the smart ring embodiment.

[0051] Figure 2 This is a front view of the wearable device 100 in the first embodiment of this application. Figure 3 for Figure 2 The left view of the wearable device 100 shown. Figure 4 for Figure 2 The image shown is a stereoscopic view of the wearable device 100 from one perspective. Figure 5 for Figure 2A stereoscopic view of the wearable device 100 from another perspective.

[0052] like Figure 2 and Figure 3 As shown, the wearable device 100 includes a wearing ring 1, an adjustment structure 2, and electronic components 3.

[0053] like Figure 4 and Figure 5 As shown, the wearing ring 1 is used to be fitted onto the wearing part (such as a finger). The wearing ring 1 is broken in its circumferential direction P, and the wearing ring 1 has a first overlapping segment 11 and a second overlapping segment 12 at the break. The first overlapping segment 11 and the second overlapping segment 12 overlap in the circumferential direction P of the wearing ring 1, and the first overlapping segment 11 and the second overlapping segment 12 are arranged along the axial direction Z of the wearing ring 1.

[0054] It is necessary to understand that, such as Figure 1 and Figure 2 As shown, the axial direction Z of the wearing ring 1 is parallel to the central axis O of the wearing ring 1, as... Figure 1 As shown, in the main viewing direction of the wearing ring 1, the central axis O passes through the center of the wearing ring 1; wherein, as Figure 1 As shown, in the main viewing direction of the wearing ring 1, the wearing ring 1 can be a circular ring, and the center of the wearing ring 1 is the center of the circular ring; but it is not limited to this. In the main viewing direction of the wearing ring 1, the wearing ring 1 can also be an elliptical ring, and the center of the wearing ring 1 is the center of symmetry of the elliptical ring (i.e., the intersection of the minor axis and the major axis).

[0055] The wearing ring body 1 has a first receiving cavity 13, which extends along the circumferential direction P of the wearing ring body 1. One end of the first receiving cavity 13 extends into the first overlapping section 11, and the other end of the first receiving cavity 13 extends into the second overlapping section 12. The electronic device 3 is disposed in the first receiving cavity 13.

[0056] Among them, such as Figure 4 and Figure 5 As shown, the first receiving cavity 13 can be a receiving groove, with a receiving opening on the side near the central ring opening 10. The first receiving cavity 13 can be filled with encapsulating adhesive (not shown in the figure) to encapsulate the internal electronic device 3. However, it is not limited to this; the first receiving cavity 13 can also be a hollow cavity within the wearing ring body 1.

[0057] The adjustment structure 2 connects the first overlapping segment 11 and the second overlapping segment 12, making the overlap length of the first overlapping segment 11 and the second overlapping segment 12 in the circumferential direction P of the wearing ring 1 adjustable, thereby making the size of the central ring opening 10 of the wearing ring 1 adjustable. Thus, in actual use, the size of the central ring opening 10 of the wearing device 100 can be adjusted according to the size of the user's wearing area (such as the finger circumference), thereby meeting the wearing needs of different users.

[0058] In this embodiment of the wearable device 100, since the first overlapping segment 11 and the second overlapping segment 12 overlap in the circumferential direction P, one end of the first receiving cavity 13 extends into the first overlapping segment 11, and the other end of the first receiving cavity 13 extends into the second overlapping segment 12. In other words, in addition to having the first receiving cavity 13 around the entire circumference P, the overlapping segment of the wearable ring 1 also has an additional first receiving cavity 13. This greatly increases the space of the first receiving cavity 13, which not only facilitates the arrangement of more electronic devices 3 within the wearable ring 1 to expand the functionality of the wearable device 100, but also allows the electronic devices 3 to be arranged at different positions along the circumferential direction P according to actual functional needs, thus facilitating the optimized layout of the electronic devices 3. Furthermore, since the first overlapping segment 11 and the second overlapping segment 12 are arranged along the axial direction Z of the wearable ring 1, this avoids the overlapping segment compressing the space of the central ring opening 10, thereby preventing interference between the overlapping segment and the wearing part and affecting the user's wearing comfort.

[0059] In some embodiments, the adjustment structure 2 can be the following structure, such as Figure 6 , Figure 7 and Figure 8 As shown, Figure 6 for Figure 2 The exploded view of the wearable device 100 shown is shown. Figure 7 for Figure 5 A schematic diagram of the cross-section (the cross-section is perpendicular to the axis Z) of the wearable device 100 at the position of the adjustment structure 2. Figure 8 for Figure 5 A schematic diagram of a longitudinal section (the section is parallel to the axis Z) of the wearable device 100 at the position of the adjustment structure 2. The adjustment structure 2 includes a first slot 21 and a second receiving cavity 22 disposed in the first overlapping section 11, a locking member 23 disposed in the second receiving cavity 22, and a first pin 24 disposed in the second overlapping section 12.

[0060] like Figure 7 As shown, the first slot 21 extends along the circumferential direction P of the wearing ring 1 and communicates with the second receiving cavity 22; as Figure 5 and Figure 6As shown, the locking member 23 is provided with a plurality of locking parts 231 arranged along the circumferential direction P of the wearing ring body 1, and the first pin 24 extends into the second receiving cavity 22 from the first slot 21.

[0061] The first pin 24 can be connected to and disconnected from the locking part 231. For example... Figure 5 and Figure 8 As shown, when the first pin 24 is connected to the locking part 231, the locking member 23 prevents the first pin 24 from moving along the first slot 21, so as to prevent the overlap length of the first overlapping section 11 and the second overlapping section 12 from changing, thus fixing the size of the central ring opening 10 of the wearing ring body 1.

[0062] When the first pin 24 is separated from the locking part 231, the first pin 24 can move along the first slot 21 to change the overlap length of the first overlapping section 11 and the second overlapping section 12, so that the size of the central ring 10 of the wearing ring body 1 can be adjusted to meet the wearing needs of different users.

[0063] By configuring the adjustment structure 2 as described above, the first pin 24 is connected to multiple locking parts 231, allowing for multi-level adjustment of the size (e.g., diameter) of the central ring opening 10 of the wearing ring 1. When the first pin 24 is connected to a locking part 231, the locking part 231 locks the first pin 24 in a fixed position, thus fixing the size of the central ring opening 10. This eliminates the clamping force on the user's wearing area, increasing the comfort of the wearing device 100. Furthermore, this adjustment structure 2 is a mechanical structure, consumes no electrical energy, and does not affect the battery life of the wearing device 100.

[0064] In some embodiments, such as Figure 5 As shown, the second receiving cavity 22 is separated from the first receiving cavity 13 by a partition wall 17, and the adjustment structure 2 also includes a first cover plate (not shown in the figure), which covers the second receiving cavity 22.

[0065] The structure of the locking element 23 is not unique; in some embodiments, such as... Figure 5 and Figure 6 As shown, the locking member 23 can be a rack with multiple ratchet teeth 232 arranged circumferentially P along the wearing ring body 1; the ratchet teeth 232 have a stop tooth surface 2321 and a guide tooth surface 2322, the guide tooth surface 2322 being located on one side of the stop tooth surface 2321 near the end of the first overlapping section 11 (e.g. Figure 6 (As shown on the left), the guide tooth surface 2322 is inclined relative to the stop tooth surface 2321, and the locking part 231 is the tooth groove between two adjacent ratchet teeth 232, and the end of the first pin 24 extends into it.

[0066] The wearing ring 1 is elastic. When the first pin 24 separates from the locking part 231, under the action of the elastic force of the wearing ring 1 itself, the second overlapping section 12 can drive the first pin 24 to move towards the end of the first slot 21 near the end of the first overlapping section 11 (for example). Figure 6 (as shown at the left end of the first slot 21) to reduce the overlap length.

[0067] When it is necessary to adjust the size of the central opening 10 of the wearing ring 1, the user can manually squeeze the wearing ring 1 to move the first pin 24 out of the locking part 231 under the guidance of the guide tooth surface 2322, and to the side away from the end of the first overlapping section 11 (e.g. Figure 6 The right side shown moves along the locking member 23, thereby increasing the overlap length of the first overlapping segment 11 and the second overlapping segment 12, which in turn makes the central ring opening 10 of the wearing ring body 1 smaller until it reaches the preset size.

[0068] When the wearing ring 1 needs to be reset, the user moves the first pin 24 out of the locking part 231. At this time, under the action of the elastic force of the wearing ring 1 itself, the second overlapping section 12 can drive the first pin 24 towards the end of the first overlapping section 11 of the first slot 21 (e.g., Figure 6 The left end of the first slot 21 shown is moved to reduce the overlap length until the center ring 10 of the wearing ring body 1 becomes the largest.

[0069] By configuring the locking member 23 as a rack with ratchet teeth 232, when adjusting the size of the central ring opening 10 of the wearing ring 1, the user can manually squeeze the wearing ring 1 to move the first pin 24 along the locking member 23 towards the end away from the first overlapping section 11 under the guidance of the guide tooth surface 2322. This eliminates the need for the user to manually remove the first pin 24 from the locking part 231, simplifying the user's operation and improving the user experience. Furthermore, the elasticity of the wearing ring 1 reduces the overlap length between the first overlapping section 11 and the second overlapping section 12, meaning the elasticity of the wearing ring 1 enlarges the central ring opening 10. Therefore, when the first pin 24 is removed from the locking part 231 and the size of the central ring opening 10 is adjusted, the wearing ring 1 can avoid generating excessive clamping force on the wearing area, making the wearing device 100 more comfortable to wear.

[0070] The material of the wearing ring 1 can be a high-elasticity alloy, such as nickel-based elastic alloy (e.g., Ni-Cr-Co-Mo alloy), cobalt-based elastic alloy (e.g., Co-Ni-Cr-Mo alloy), iron-based elastic alloy (e.g., Fe-Cr-Ni-Ti alloy), etc.

[0071] Of course, the stop tooth surface 2321 and guide tooth surface 2322 of the ratchet 232 can also be interchanged, as follows: In some embodiments, the guide tooth surface 2322 is located on the side of the stop tooth surface 2321 away from the end of the first overlapping section 11. When the first pin 24 is separated from the locking part 231, under the action of the elastic force of the wearing ring 1, the second overlapping section 12 can drive the first pin 24 to move towards the end of the first slot 21 away from the end of the first overlapping section 11, so as to reduce the overlap length.

[0072] When the size of the central opening 10 of the wearing ring 1 needs to be adjusted, the user can pry the wearing ring 1 so that the first pin 24 moves out of the locking part 231 under the guidance of the guide tooth surface 2322 and moves along the locking member 23 towards the end of the first overlapping section 11. This reduces the overlap length between the first overlapping section 11 and the second overlapping section 12, thereby increasing the size of the central opening 10 of the wearing ring 1 until the preset size is reached. When the wearing ring 1 needs to be reset, the user moves the first pin 24 out of the locking part 231. At this time, under the action of the elastic force of the wearing ring 1 itself, the second overlapping section 12 can drive the first pin 24 to move towards the end of the first slot 21 away from the end of the first overlapping section 11, thereby increasing the overlap length until the central opening 10 of the wearing ring 1 becomes the smallest.

[0073] In some embodiments, such as Figure 6 , Figure 8 and Figure 9 As shown, Figure 9 for Figure 8 The diagram shows a partial structural view of the wearing device 100. The second overlapping section 12 has a pin receiving groove 121, which extends along the axial direction Z of the wearing ring body 1. A portion of the first pin 24 slides within the pin receiving groove 121, and the other portion of the first pin 24 extends from the first slot 21 into the second receiving cavity 22. The adjustment structure 2 also includes an elastic element 25 disposed in the pin receiving groove 121. The elastic element 25 is connected between the groove wall of the pin receiving groove 121 and the first pin 24, and is used to apply an elastic force to the first pin 24, which causes the first pin 24 to move towards the locking member 23.

[0074] By providing a pin receiving groove 121, the pin receiving groove 121 can guide the first pin 24, preventing the first pin 24 from deflecting during movement, thus ensuring that the first pin 24 accurately connects and separates from the locking part 231. By providing an elastic element 25, when the first pin 24 is positioned relative to the locking part 231, it can approach and connect to the locking part 231 under the elastic force of the elastic element 25. This eliminates the need for manual adjustment of the position of the first pin 24 to connect with the locking part 231, simplifying user operation and improving the user experience.

[0075] The type of elastic element 25 is not unique, for example Figure 8 and Figure 9 As shown, the elastic element 25 can be a spring, with one end of the spring abutting against the first pin 24 and the other end of the spring abutting against the groove wall of the pin receiving groove 121. However, it is not limited to this; the elastic element 25 can also be a spring sheet.

[0076] When it is necessary to remove the first pin 24 from the locking part 231, in order to facilitate user operation of the first pin 24, in some embodiments, such as Figure 8 , Figure 9 and Figure 10 As shown, Figure 10 for Figure 5 A schematic diagram of the structure of the first pin 24 of the wearable device 100 is shown. The pin receiving groove 121 has a slot 1211 on one side near the central ring opening 10 of the wearing ring body 1. A cover plate 122 is provided at the slot 1211, which covers a part of the slot 1211. The other part of the slot 1211 forms a clearance opening 1212. A toggle part 242 is fixedly provided on the first pin 24. The toggle part 242 extends from the clearance opening 1212 to the outside of the second overlapping section 12.

[0077] By providing the actuating part 242, the user can move the first pin 24, thus facilitating its operation. By providing the cover plate 122, a portion of the pin receiving groove 121 is covered, protecting the components within. By providing the clearance opening 1212, movement interference between the actuating part 242 and the cover plate 122 is avoided.

[0078] In some embodiments, such as Figure 5 As shown, the slot 1211 of the pin receiving groove 121 and the cavity opening of the second receiving cavity 22 are both positioned facing the central ring opening 10. This arrangement prevents the adjustment structure 2 from being exposed on the outside of the wearing ring body 1 (the side away from the central ring opening 10), thus avoiding affecting its appearance.

[0079] To ensure a more secure engagement between the first pin 24 and the locking portion 231 when the first pin 24 is inserted into the locking portion 231, in some embodiments, a pin bevel 241 is provided at the end of the first pin 24. The pin bevel 241 is inclined relative to the length direction Z of the first pin 24 and is used to contact the guide tooth surface 2322. By providing the pin bevel 241, the shape of the end of the first pin 24 can match the shape of the locking portion 231, increasing the contact area between the first pin 24 and the locking portion 231. This makes it less likely for the first pin 24 to disengage from the locking portion 231, thereby ensuring a more secure engagement between the first pin 24 and the locking portion 231.

[0080] The first pin 24 can have the following structure, such as Figure 9 and Figure 10 As shown, the first pin 24 includes an insertion section 243 and a mating section 244 connected to each other. The insertion section 243 extends into the second receiving cavity 22 and is connected to the locking member 23. The mating section 244 is slidably engaged with the pin receiving groove 121. The actuating part 242 is fixed to the mating section 244. The pin inclined surface 241 is provided at the end of the insertion section 243.

[0081] In some embodiments, such as Figure 9 and Figure 10 As shown, the first pin 24 also includes a connecting post 245, which is located on the side of the mating section 244 away from the insertion section 243. The elastic element 25 is a spring, with one end of the spring sleeved on the outside of the connecting post 245 and abutting against the mating section 244. By providing the connecting post 245 and sleeved the elastic element 25 on it, the connecting post 245 can limit one end of the elastic element 25, preventing significant misalignment between the elastic element 25 and the first pin 24, thereby improving the reliability of the connection between the elastic element 25 and the first pin 24.

[0082] In this embodiment, the locking member 23 can be a rack or pinion, or it can be a perforated plate. Along the circumferential direction P of the wearing ring 1, the perforated plate is provided with a plurality of pin holes, which are the locking parts 231.

[0083] In order to achieve an optimized layout of the electronic device 3 within the first receiving cavity 13 of the wearing ring 1, in some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, the wearing ring 1 includes a first semi-ring segment 14 and a second semi-ring segment 15 connected to each other. The first semi-ring segment 14 includes a first overlapping segment 11, and the second semi-ring segment 15 includes a second overlapping segment 12. The first semi-ring segment 14 extends along a spatial curve, and the second semi-ring segment 15 extends along a planar curve. The electronic device 3 includes a battery 31 and a flexible circuit board (not shown) electrically connected to the battery 31. The battery 31 is located in a first receiving cavity 13 within the second semi-ring segment 15, and the flexible circuit board is located in a first receiving cavity 13 within the first semi-ring segment 14.

[0084] The aforementioned spatial curve is a virtual curve reflecting the extension direction of the first semi-ring segment 14. Each point on the spatial curve is not in the same plane. For example, the spatial curve can be a spiral. The aforementioned planar curve is a virtual curve reflecting the extension direction of the second semi-ring segment 15. Each point on the planar curve is in the same plane. For example, the planar curve can be an arc.

[0085] By placing the battery 31 within the first receiving cavity 13 in the second semi-annular segment 15, damage caused by spatial distortion of the battery 31 can be avoided, thus ensuring the lifespan of the battery 31. By placing the flexible circuit board within the first receiving cavity 13 in the first semi-annular segment 14, the flexibility of the flexible circuit board can be fully utilized, allowing the flexible circuit board to adapt well to the spatial distortion within the first semi-annular segment 14.

[0086] In some embodiments, the electronic device 3 further includes sensors disposed on a flexible circuit board. The number of sensors can be one or more, such as an accelerometer, a pedometer, a gyroscope, a heart rate sensor, a pulse oximeter, a sleep monitor, a thermometer, and an electrocardiogram sensor. The sensors are configured to sense changes in the condition of the user to be monitored.

Figure 12 This is a schematic diagram of the wearable device 100 in the second embodiment of this application from a second perspective. Figure 13 for Figure 12 A partial view of the wearable device 100 at the first overlapping segment 11. Figure 14 for Figure 12 The shown is a longitudinal sectional view of the wearable device 100 at the first pin 24. Figure 15 This is a schematic diagram of the wearable device 100 in the second embodiment of this application from a third-person perspective. Figure 16 for Figure 15 A partial view of the wearable device 100 at the second overlapping segment 12. Figure 17 for Figure 15 The wearable device 100 shown is a longitudinal sectional view at the second pin 27.

[0088] Figures 11-17 The wearable device 100 shown is Figures 2 to 10 The main difference between the wearable devices 100 shown is that the specific structure of the adjustment structure 2 is different. Figures 11-17 The wearable device 100 shown omits the locking element 23, as detailed below:

[0089] In some embodiments, such as Figure 12 , Figure 13 and Figure 14 As shown, the adjustment structure 2 includes a first slot 21 disposed in the first overlapping section 11 and a first pin 24 disposed in the second overlapping section 12. The first slot 21 extends along the circumferential direction P of the wearing ring body 1, and the first pin 24 extends into the first slot 21.

[0090] Wearing ring 1 is a reverse characteristic shape memory alloy. When the temperature of wearing ring 1 is higher than the phase transition temperature of its material, wearing ring 1 can deform, allowing the first pin 24 to move along the first slot 21, thereby making the overlap length adjustable. When the temperature of wearing ring 1 is lower than the phase transition temperature of its material, the position of the first pin 24 relative to the first slot 21 is fixed, and the overlap length is fixed.

[0091] This embodiment achieves adjustment of the size of the central loop 10 by utilizing the temperature-dependent characteristics of the wearing ring 1. Adjusting the size of the central loop 10 requires heating the wearing ring 1 to above the phase transition temperature of its material. Then, by deforming the wearing ring 1, the first pin 24 can move along the first slot 21, thereby adjusting the size of the central loop 10 to a preset size. Once the wearing ring 1 cools below its material phase transition temperature and its shape is fixed, the adjustment is complete. This adjustment method allows for stepless adjustment of the size of the central loop 10 of the wearing ring 1, better matching the size of different users' wearing areas. Furthermore, this adjustment structure 2 is a mechanical structure, does not consume electrical energy, and does not affect the battery life of the wearing device 100.

[0092] Among them, inverse shape memory alloys are a type of smart material with a special temperature response mechanism. Their shape change pattern is exactly the opposite of that of conventional shape memory alloys. The core characteristic is that they "exhibit a deformable state at high temperatures and automatically recover and stably maintain the preset parent phase shape at low temperatures." This unique performance stems from the inverse phase transformation characteristics of their internal crystal structure—high temperature induces martensitic phase transformation, and low temperature triggers austenitic phase transformation, thereby realizing the functional logic of "high temperature shaping and low temperature fixation".

[0093] Reverse shape memory alloys include copper-based alloys, nickel-titanium-based alloys, and iron-based alloys. Copper-based alloys, such as the Cu-Zn-Al system, can have their phase transformation temperature controlled between 80℃ and 200℃ by adjusting their composition. They can be easily bent and stretched into complex temporary shapes at high temperatures, and automatically return to their initial stable form after cooling to room temperature. They are low-cost and have excellent processing performance. Nickel-titanium-based alloys, such as the Ni-Ti-Cu system, have their phase transformation temperature increased to 100℃ to 300℃ by doping with elements such as copper and niobium, and they also possess good corrosion resistance and fatigue performance. Iron-based alloys, such as the Fe-Mn-Si-Cr system, are inexpensive and have high strength, with a phase transformation temperature reaching 100℃ to 250℃, and outstanding high-temperature plasticity.

[0094] In order to prevent damage to the electronic device 3 due to high temperature when the wearing ring 1 is heated above the phase transition temperature, in some embodiments, the material of the wearing ring 1 is a copper-based alloy with a phase transition temperature of 80°C to 90°C.

[0095] To further prevent damage to the electronic device 3 due to high temperature when the wearing ring 1 is heated above the phase transition temperature, in some embodiments, an insulating layer is provided between the electronic device 3 and the surface of the wearing ring 1.

[0096] During use of the wearable device 100, to prevent the first pin 24 from moving out of the first slot 21, in some embodiments, such as Figure 12 and Figure 14 As shown, the adjustment structure 2 includes a second receiving cavity 22 disposed in the first overlapping section 11. The first slot 21 is connected to the second receiving cavity 22. The first pin 24 extends into the second receiving cavity 22 from the first slot 21. The first pin 24 is provided with a first limiting part 246, which is located in the second receiving cavity 22 and can stop at the edge of the first slot 21 to prevent the first pin 24 from moving out of the first slot 21. By providing the first limiting part 246 on the first pin 24, the first limiting part 246 can play the role of axially limiting the first pin 24, preventing the first pin 24 from moving out of the first slot 21, thereby ensuring the reliability of the connection between the first overlapping section 11 and the second overlapping section 12.

[0097] To prevent the ends of the overlapping sections of the wearing ring 1 from warping due to stress and affecting the shape of the wearing ring 1, in some embodiments, such as Figure 15 , Figure 16 and Figure 17 As shown, the adjustment structure 2 also includes a second slot 28 disposed in the second overlapping section 12 and a second pin 27 disposed in the first overlapping section 11; the second slot 28 extends circumferentially P along the wearing ring body 1, and the second pin 27 slides in engagement with the second slot 28. Figure 12 and Figure 15 As shown, when the overlap length is at its maximum value, the first slot 21 and the second slot 28 are staggered along the circumferential direction P of the wearing ring body 1, and the first pin 24 is located at one end of the first slot 21 away from the end of the first overlap segment 11, and the second pin 27 is located at one end of the second slot 28 away from the end of the second overlap segment 12.

[0098] With this configuration, the first pin 24 can limit the end of the first overlapping segment 11, preventing the end of the first overlapping segment 11 from warping due to stress; the second pin 27 can limit the end of the second overlapping segment 12, preventing the end of the second overlapping segment 12 from warping due to stress, thus ensuring the roundness of the wearing ring 1.

[0099] In some embodiments, such as Figure 12 and Figure 15As shown, one end of the first slot 21 extends to the end of the first overlapping segment 11, and one end of the second slot 28 extends to the end of the second overlapping segment 12. This configuration allows the first pin 24 to move to the end of the first overlapping segment 11, providing better restraint and preventing the end of the first overlapping segment 11 from warping due to stress. Similarly, the second pin 27 can move to the end of the second overlapping segment 12, providing better restraint and preventing the end of the second overlapping segment 12 from warping due to stress.

[0100] During use of the wearable device 100, to prevent the second pin 27 from moving out of the second slot 28, in some embodiments, such as Figure 15 and Figure 17 As shown, the adjustment structure 2 includes a third receiving cavity 29 disposed in the second overlapping section 12, the second slot 28 is connected to the third receiving cavity 29, and the second pin 27 extends into the third receiving cavity 29 from the second slot 28; the second pin 27 is provided with a second limiting part (not shown in the figure), the second limiting part is located in the third receiving cavity 29, and is used to stop at the edge of the second slot 28 to prevent the second pin 27 from moving out of the second slot 28.

[0101] By providing a second limiting part on the second pin 27, the second limiting part can play the role of axially limiting the second pin 27, preventing the second pin 27 from moving out of the second slot 28, thereby ensuring the reliability of the connection between the first overlapping section 11 and the second overlapping section 12.

[0102] In some embodiments, such as Figure 12 As shown, the adjustment structure 2 also includes a first cover plate (not shown in the figure) and a second cover plate (not shown in the figure). The first cover plate covers the second receiving cavity 22, and the second cover plate covers the third receiving cavity 29.

[0103] In some embodiments, such as Figure 12 As shown, both the second receiving cavity 22 and the third receiving cavity 29 are L-shaped.

[0104] In some embodiments, such as Figure 12 As shown, the openings of the second receiving cavity 22 and the third receiving cavity 29 are both positioned facing the central ring opening 10. This arrangement prevents the adjustment structure 2 from being exposed on the outside of the wearing ring body 1 (the side away from the central ring opening 10), thus avoiding affecting its appearance.

[0105] In some embodiments, such as Figure 11As shown, the wearing ring 1 is a metal or alloy part (such as the reverse characteristic shape memory alloy mentioned above). The first overlapping section 11 and the second overlapping section 12 are respectively provided with surface treatment areas 16 on the side surface away from the central ring opening 10 of the wearing ring 1. The surface treatment area 16 includes a polishing area 161 (also called a high-gloss area), a sandblasting area 162 and a wire drawing area 163 arranged along the circumferential direction P of the wearing ring 1. The sandblasting area 162 is disposed between the polishing area 161 and the wire drawing area 163.

[0106] Because the light reflectance of the polished area 161, the sandblasted area 162, and the wire drawing area 163 has significant differences, and the light reflectance of adjacent areas is distributed with one being high and the other low, the light reflected by the polished area 161, the sandblasted area 162, and the wire drawing area 163 can be easily recognized by the human eye, thereby improving the recognition of the wearable device 100.

[0107] In addition, by using different CMF (Color, Material, Finish) designs for the polished area 161, sandblasted area 162, and brushed area 163, and combining them with the colors of other parts of the wearing ring 1, such as PVD color, the appearance of the wearing device 100 can be improved, which helps to enhance the sophistication and technological feel of the wearing device 100.

[0108] The polished area has the smoothest surface (extremely low roughness, Ra is usually <0.1μm), mainly exhibiting specular reflection and the highest reflectivity. The polished surfaces of metallic materials (such as stainless steel and aluminum) can have a visible light reflectivity of 70%-90%, even approaching that of a mirror (such as chrome-plated polished parts with a reflectivity exceeding 90%). The light reflection direction is concentrated, resulting in a strong visual highlight.

[0109] Brushed area: The surface has regular linear textures (medium roughness, Ra about 0.1-1μm), mainly directional diffuse reflection, and the reflectivity is lower than that of the polished area. The visible light reflectivity of the brushed metal surface is usually 30%-60%, and the light is somewhat concentrated along the texture direction, but due to the scattering of the texture, the intensity of the highlights is weakened, presenting a uniform matte texture.

[0110] Sandblasted area: The surface is formed with irregular uneven textures by particle impact (highest roughness, Ra>1μm), mainly diffuse reflection, with the lowest reflectivity. The reflectivity of metal sandblasted surfaces to visible light is generally 10%-30%. The rough structure causes light to scatter in all directions, with almost no obvious highlights, and visually presents a matte or dull texture.

[0111] In some embodiments, such as Figure 11 As shown, the dividing lines between adjacent areas in the polishing area 161, sandblasting area 162, and wire drawing area 163 are engraved lines.

[0112] Figure 18This is a schematic diagram of the structure of an electronic system in some embodiments of this application. The electronic system includes a charging dock 200 and a wearable device 100 as described in any of the above embodiments, wherein the charging dock 200 is used to charge the wearable device 100.

[0113] The charging base 200 has a charging area 210 with charging contacts. The wearable device 100 has a connecting contact that abuts against the charging contacts to enable the charging base 200 to charge the wearable device 100.

[0114] In some embodiments, such as Figure 18 As shown, the charging dock 200 is a charging box, and includes a box body 230 and a box cover 240. The box body 230 has a box cavity, and a charging contact is provided in the box cavity. The box cavity constitutes the charging area 210 of the charging dock 200. The box cavity is used to place the wearable device 100. The box cover 240 is rotatably connected to the edge of the box body 230 and is used to open and close the box cavity of the box body 230.

[0115] In some embodiments, the charging contacts may be disposed on the side wall of the cavity; however, this is not a limitation, and in other embodiments, the charging contacts may also be disposed on the bottom wall of the cavity.

[0116] Of course, the charging stand 200 is not limited to a charging box; it can also be set to other shapes, such as a disc, depending on the actual situation.

[0117] Figure 19 This is a schematic diagram of the electronic system in some other embodiments of this application. Figure 19 The electronic system shown is Figure 18 The main difference between the electronic systems shown is: Figure 19 The charging dock 200 of the electronic system shown is equipped with a heating element 220, as described below:

[0118] like Figure 19 As shown, the electronic system includes a charging base 200 and a wearable device 100 as described in the second embodiment above. The charging base 200 is provided with a charging area 210 for setting the wearable device 100. The charging area 210 is provided with a heating element 220 for heating the wearing ring 1 of the wearable device 100.

[0119] By setting a heating element 220 in the charging area 210, when it is necessary to adjust the size of the central ring 10 of the wearing ring 1, the wearing ring 1 can be heated to above the phase change temperature by the heating element 220. The charging base 200 can both charge and heat, so there is no need to set up an additional heating component, which helps to reduce costs.

[0120] In some embodiments, such as Figure 19As shown, the charging dock 200 is a charging case, including a body 230 and a lid 240. The body 230 has a cavity containing charging contacts, which forms the charging area 210 of the charging dock 200. The cavity is used to hold the wearable device 100. The lid 240 is rotatably connected to the edge of the body 230 and is used to open and close the cavity. The heating element 220 is a heating layer covering the bottom wall of the cavity, and the charging contacts are located on the side wall of the cavity.
