Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] In one embodiment of this utility model, according to Figure 1-4 As shown, the device includes a wearable body 100 and a connecting strap 210. The wearable body 100 includes a housing 110; the housing 110 has a mounting cavity 120, and a heating element 130 is located within the mounting cavity 120. A first heat-conducting element 140 is located on the heating element 130. The housing 110 has symmetrical connecting slots 150 on both sides, connecting to the outside. The connecting strap 210 has connecting shafts 220 at both ends, which can be respectively inserted into the two connecting slots 150 to achieve a detachable connection between the wearable body 100 and the connecting strap 210. Specifically, the heating element 130 mainly consists of a chip, battery, and wireless communication module. Wearable products such as smartwatches and bracelets have a compact structure and limited internal heat dissipation space, resulting in limited heat dissipation methods. Furthermore, accessories such as the connecting strap 210 are usually designed to be detachable, making it difficult to transfer heat to the connecting strap 210. For a long time, accessories such as the connecting strap 210 have offered no benefit to heat dissipation or signal transmission. However, the connecting strip 210 has a large surface area, and if it can achieve thermal conductivity with the main body, it will have a very significant effect on improving heat output.

[0031] The first heat-conducting element 140 extends to both sides and abuts against the first wall surface 151 of the two connecting grooves 150. The connecting shaft 220 abuts against the second wall surface 152 of the connecting groove 150. The connecting strip 210 is embedded with a second heat-conducting element 160, which is connected to the connecting shaft 220. Both the connecting groove 150 and the connecting shaft 220 are made of heat-conducting material. The heat generated by the heating element 130 is conducted to the second heat-conducting element 160 through the first heat-conducting element 140, the connecting groove 150, and the connecting shaft 220 for auxiliary heat dissipation. Specifically, two connecting grooves 150 are symmetrically arranged on the side of the outer shell 110. The two connecting grooves 150 are not connected to the mounting cavity 120 but are connected to the outside. The side of the connecting groove 150 is connected to the outside through the first opening 153, and both ends of the connecting groove 150 are connected to the outside through the second opening 155. The first opening 153 and the two second openings 155 are also interconnected. Both the connecting groove 150 and the connecting shaft 220 are made of thermally conductive materials. The first thermally conductive element 140 conducts the heat from the heating element 130 to the first wall surface 151, and the first wall surface 151 conducts the heat to the second wall surface 152. The connecting shaft 220 abuts against the second wall surface 152, and the heat is conducted to the connecting shaft 220. The connecting band 210 is embedded with a second thermally conductive element 160, which is connected to the connecting shaft 220. The heat is conducted from the connecting shaft 220 to the second thermally conductive element 160. The length of the second thermally conductive element 160 can be equal to or slightly less than the length of the connecting band 210. With a long length and large area, the heat inside the wearable device can be quickly dissipated.

[0032] Specifically, by setting the connecting groove 150 and the connecting shaft 220, the wearable body 100 and the connecting strap 210 can be detachably connected. The connecting strap 210 can be replaced at will to meet different wearing needs. At the same time, the first heat-conducting element 140 and the second heat-conducting element 160 can transfer the heat inside the wearable body 100 to the connecting strap 210, which can quickly dissipate the heat inside the wearable device and meet the user's need for the wearable device not to overheat when wearing it.

[0033] Furthermore, both the connecting groove 150 and the connecting shaft 220 are made of thermally conductive materials, such as aluminum alloy, copper alloy, or other high thermally conductive materials.

[0034] Furthermore, the connecting shaft 220 of the wearable body 100 and the connecting strap 210 can be made of high thermal conductivity materials such as aluminum alloy and copper alloy, and the second thermal conductive component 160 is embedded in the middle of the strap through an integrated molding process.

[0035] Furthermore, the connecting shaft 220 may include a single shaft or a connecting shaft 220 composed of multiple shafts connected together. The number of shafts is not limited, and all are within the protection scope of this utility model patent. Multiple shafts can be understood as multiple shafts arranged in series and connected together by fasteners to form the connecting shaft 220, thereby increasing the contact area.

[0036] In another embodiment of this utility model, according to Figure 1-4 As shown, the connecting strap 210 can be integrally molded and fitted onto the hand, or it can consist of a first strap body 211 and a second strap body 212. The first strap body 211 and the second strap body 212 can be fitted and fixed onto the hand via a connecting assembly. Both the first strap body 211 and the second strap body 212 have a second heat-conducting element 160 embedded within them, with one end of the second heat-conducting element 160 abutting against the connecting shaft 220. The connecting assembly can be any quick-release structure available on the market, as long as it allows for a detachable connection between the first strap body 211 and the second strap body 212.

[0037] In another embodiment of this utility model, according to Figure 1 , 3 As shown in Figure 4, the connecting groove 150 includes a cavity 154 and a first opening 153 entering the cavity 154; the size of the first opening 153 is smaller than the size of the cavity 154. The connecting groove 150 also includes two second openings 155 entering the cavity 154, and the connecting shaft 220 can be inserted into the cavity 154 through either of the second openings 155. Specifically, the connecting shaft 220 can only be inserted through the second opening 155, and cannot be inserted through the first opening 153. The thickness of the connecting strip 210 is smaller than the diameter of the connecting shaft 220. The size of the connecting shaft 220 and the cavity 154 are mutually matched and fitted. When the connecting shaft 220 is inserted into the connecting groove 150 through the second opening 155, the connecting strip 210 is inserted through the first opening 153, and the connecting shaft 220 will not fall out of the first opening 153, thus ensuring structural stability.

[0038] Each connecting groove 150 is also provided with a locking component, including a pressing component 310; the connecting groove 150 is provided with a snap-fit ​​groove 320, and a pin 330 is provided in the snap-fit ​​groove 320. The pin 330 is connected to the pressing component 310. The connecting shaft 220 is provided with a snap-fit ​​hole 340, and an elastic reset snap-fit ​​member 350 is provided in the snap-fit ​​hole 340. When the connecting shaft 220 passes through the connecting groove 150, the elastic reset snap-fit ​​member 350 retracts into the snap-fit ​​hole 340. When it passes through to the designated position, the snap-fit ​​groove 320 and the snap-fit ​​hole 340 are arranged opposite to each other, and the elastic reset snap-fit ​​member 350 can extend into the snap-fit ​​groove 320 to achieve snap-fit ​​fastening. The pressing component 310 can control the extension and retraction of the pin 330 in the snap-fit ​​groove 320. When the pin 330 extends, it abuts against and presses the elastic reset snap-fit ​​member 350 to retract, releasing the snap-fit ​​fastening state.

[0039] It is understood that the elastic reset snap-fit ​​component 350 includes a spring and a snap-fit ​​block. The top of the snap-fit ​​block has a smooth arc corner. When the connecting shaft 220 passes through the connecting groove 150, the snap-fit ​​block touches the second wall surface 152. The force compresses the spring, and the snap-fit ​​block retracts into the snap-fit ​​hole 340. When it passes through to the designated position, the snap-fit ​​block is directly opposite the snap-fit ​​groove 320, and the force disappears. Under the action of the spring, the snap-fit ​​block can extend into the snap-fit ​​groove 320 to achieve the snap-fit ​​fastening of the connecting shaft 220 and the connecting groove 150. When it is necessary to remove the connecting band 210, the pressing component 310 includes a pressing block connected to a pin 330. Pressing the pressing block causes the pin 330 to extend upward and press against the snap-fit ​​block, which retracts into the snap-fit ​​hole 340, thereby releasing the snap-fit ​​fastening state. At this time, the connecting band 210 can be pulled out. It is also understood that the pressing component 310 may include a spring, which allows the pressing block to automatically reset after being pressed, making it more convenient.

[0040] In another embodiment of this utility model, according to Figure 3 and 4 As shown, the first heat-conducting component 140 includes a heat-conducting main body 141 in the middle and heat-conducting connecting parts 142 at both ends. The heat-conducting main body 141 and the heat-conducting connecting parts 142 at both ends are integrally formed. Each heat-conducting connecting part 142 has the same shape as the first wall surface 151 and is tightly attached to the first wall surface 151. Specifically, the fact that the heat-conducting connecting part 142 has the same shape as the first wall surface 151 can increase the contact area and improve the heat conduction effect.

[0041] In another embodiment of this utility model, according to Figure 1-4 As shown, the first heat-conducting element 140 can be one of graphite film, graphene film, copper foil, aluminum foil, and boron nitride film. The second heat-conducting element 160 can also be one of graphite film, graphene film, copper foil, aluminum foil, and boron nitride film. All of the above materials have good thermal conductivity. Graphite film and graphene film are preferred in the second heat-conducting element 160 because they have strong bending resistance; after 300,000 bends, the thermal conductivity remains almost unchanged. Meanwhile, when the connecting band 210 is embedded with conductive films such as copper foil and aluminum foil, and an electrical connection can be achieved between the watch band connecting shaft 220 and the connecting lock hole, the connecting band 210 can also act as a watch antenna, greatly enhancing the watch's signal transmission and reception capabilities.

[0042] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
