[0002] Smart watches are gradually becoming one of the main smart wearable devices. Smart watches are becoming more and more versatile, not only can they realize call and positioning functions, but also network communication, such as WeChat voice or WeChat video. However, due to the small size of smart watches, so many functions are integrated inside the smart watch. When the smart watch has more functions turned on (such as starting positioning and network communication at the same time), or when there is a malfunction in use (for example: the lithium battery inside the smart watch short-circuits abnormally), the bottom of the smart watch head will cause the heat to rise in temperature due to the inability to dissipate in time. When such an abnormality occurs, some users (such as the elderly or children wearing smart watches) may not be able to quickly remove the strap by themselves, which may easily cause burns to the user due to the bottom of the smart watch head being close to the user's skin. Summary of the invention

[0003] An embodiment of the present application provides a smart watch, which includes a strap and a watch head; the smart watch also includes a connecting mechanism and a thermal strain structure, the connecting mechanism includes a first connecting unit and a second connecting unit, the first connecting unit is fixedly connected to the strap, the second connecting unit is fixedly connected to the watch head, the first connecting unit can be aligned with the second connecting unit to achieve the connection between the strap and the watch head; the thermal strain structure is connected to the watch head and can be deformed by heat, so that the first connecting unit and the second connecting unit can be separated, thereby disconnecting the connection between the strap and the watch head.

[0004] The smart watch provided in the embodiment of the present application is designed with a structure that utilizes a thermal strain structure so that the strap and the watch head can be quickly separated when the watch head is overheated, thereby preventing the user from being scalded by overheating of the watch head.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The present application embodiment first provides a smart watch. Figure 1 , Figure 1 1 is a structural diagram of the connection state between the watch strap and the watch head of an embodiment of the smart watch of the present application, and the smart watch 10 includes a watch strap 100, a watch head 200, a connection mechanism 300 and a thermal strain structure 400. Specifically, the watch head 200 may include a housing, a display screen, a wireless communication device, a control circuit board, a battery, a speaker, a vibration device, etc. The detailed structure of the watch head 200 is within the scope of understanding of those skilled in the art and will not be repeated here.

[0024] Among them, the connection mechanism 300 in this embodiment includes a first connection unit 310 and a second connection unit 320, the first connection unit 310 is fixedly connected to the strap 100, and the second connection unit 320 is fixedly connected to the watch head 200, and the first connection unit 310 can be aligned with the second connection unit 320 to achieve the connection between the strap 100 and the watch head 200; optionally. In this embodiment, the thermal strain structure 400 is connected to the watch head 200 and can be deformed by heat, specifically, when the temperature of the watch head 200 is greater than the critical value of material deformation, the first connection unit 310 and the second connection unit 320 are separated, thereby disconnecting the connection between the strap 100 and the watch head 200.

[0025] Optionally, see Figure 2 , Figure 2 yes Figure 1 A schematic diagram of the structure of the smart watch in the embodiment in which the strap and the watch head are separated, wherein the first connection unit 310 and the second connection unit 320 in this embodiment are connected by snap fit, and the thermal strain structure 400 can support the first connection unit 310 so that the first connection unit 310 and the second connection unit are snap fit and separated. The specific snap fit structure of the first connection unit 310 and the second connection unit 320 can be the fit of a hook and a protrusion, etc. The detailed structural features of this part are within the scope of understanding of those skilled in the art and will not be described in detail here.

[0026] Optionally, the thermal strain structure 400 in this embodiment is a thermally variable material block 410, which can expand when heated, and then support the first connection unit 310, so that the first connection unit 310 and the second connection unit 320 are engaged and separated. In addition, in some other embodiments, the thermally variable material block 410 can also expand when heated to support the second connection unit 320. When the circuit of the watch head 200 is abnormal and causes heat, the temperature of the watch head 200 rises and is transmitted to the thermally variable material block 410, which then causes the thermally variable material block 410 to expand when heated. The buckle position at the squeeze connection is finally popped open, the strap 100 is separated from the watch head 200, and the smart watch falls off the user's wrist.

[0027] See also Figure 3 , Figure 31 is a structural diagram of the connection state between the watch strap and the watch head of another embodiment of the smart watch of the present application. Optionally, the smart watch 10 in this embodiment also includes a watch strap 100, a watch head 200, a connecting mechanism 300 and a thermal strain structure 400. Different from the previous embodiment, the first connecting unit 310 and the second connecting unit 320 of the connecting mechanism 300 in this embodiment are magnetic bodies that can be magnetically matched, and the thermal strain structure 400 can support the first connecting unit or the second connecting unit 320, so that the first connecting unit 310 and the second connecting unit 320 are magnetically separated. Among them, the first connecting unit 310 and the second connecting unit 320 can both be permanent magnets, such as magnets or magnetic materials.

[0028] Optionally, see Figure 4 , Figure 4 yes Figure 3 A schematic diagram of the structure of the smart watch in the embodiment in the state where the strap and the watch head are separated. The thermal strain structure 400 in this embodiment is a thermally variable material body 420. The thermally variable material body 420 and the second connecting unit 320 are arranged side by side and clamped between the watch head 200 and the first connecting unit 310. The thermally variable material body 420 can expand when heated, and then support the first connecting unit 310, so that a gap is generated between the first connecting unit 310 and the second connecting unit 320, thereby separating them by magnetic attraction.

[0029] Optionally, see Figure 5 , Figure 5 It is a structural schematic diagram of the connection state of the strap and the watch head of another embodiment of the smart watch of the present application, wherein the thermal strain structure 400 in this embodiment is also a thermally variable material body 420, and the thermally variable material body 420 is arranged side by side with the first connecting unit 310 and clamped between the strap 100 and the second connecting unit 320. The thermally variable material body 420 can expand when heated, and then support the second connecting unit 320, so that a gap is generated between the first connecting unit 310 and the second connecting unit 320, and then they are separated by magnetic attraction.

[0030] Optionally, see Figure 6 , Figure 6 This is a structural diagram of the connection between the strap and the watch head of another embodiment of the smart watch of the present application. The thermal strain structure 400 in this embodiment is a thermally variable material sheet 430, which is sandwiched between the first connecting unit 310 and the second connecting unit 320. The thermally variable material sheet 430 can expand when heated, and then support the first connecting unit 310 and the second connecting unit 320 on both sides, so that a gap is generated between the first connecting unit 310 and the second connecting unit 320, and then they are separated by magnetic attraction. Please refer to Figure 7 , Figure 7 yes Figure 6 A schematic structural diagram of a smart watch in an embodiment in which the strap and the watch head are separated.

[0031] in, Figures 3 to 7 The structure of the smart watch in the embodiment is that the watch head 200 and the watch strap 100 are connected by magnets, and a thermal strain structure 400 is designed at the attraction point of the watch head 200. When the abnormal circuit of the watch head 200 causes heat (the temperature of the watch head 200 rises), the thermal strain structure expands, and the expansion causes the magnets of the watch head 200 and the watch strap 100 to stagger with each other. At the same time, the distance between the two magnets is squeezed away, the suction force is weakened, the watch strap 100 and the watch head 200 are separated, and the smart watch falls off the user's wrist.

[0033] Optionally, the thermal strain structure 400 in this embodiment is a thermal deformation material block 440, which is arranged adjacent to the connecting wire 321 of the second connecting unit 320, and the two ends of the connecting wire 321 are respectively connected to the second connecting unit 320 and the control circuit board 210 of the meter head 200. The thermal deformation material block 440 can expand when heated, and support the connecting wire 321, so that the connecting wire 321 is disconnected, thereby disconnecting the second connecting unit 320, and the magnetic field disappears, and the first connecting unit 310 and the second connecting unit 320 are magnetically separated. Please refer to Fig. 9 , Fig. 9 yes Figure 8 A schematic structural diagram of a smart watch in an embodiment in which the strap and the watch head are separated.
