[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the specific embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. It is understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for the sake of ease of description, only the parts related to the present application are shown in the accompanying drawings, rather than all the contents.

[0029] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] Figure 1 A functional block diagram of a wearable device provided in an embodiment of the present application is given, referring to Figure 1 The wearable device includes a device body 1, a device housing 2, a heating module 3 and a processing module 4. Optionally, the wearable device provided by the present solution may be a smart watch, a smart bracelet, and the like.

[0031] The device housing 2 provided in the present solution is provided with a thermochromic material layer and / or the device housing 2 is a thermochromic housing. For example, a thermochromic material of a set mass or proportion is added to the plastic material used to manufacture the device housing 2, and the device housing 2 is made of the plastic material added with the thermochromic material, and the device housing 2 can change to different colors and / or transparencies at different temperatures. A thermochromic material layer can also be coated on the outer surface of the device housing 2, or a thermochromic material layer can be coated on the outer surface of the device housing 2 according to a set pattern, and when the device housing 2 is at different temperatures, the thermochromic material layer changes to different colors and / or transparencies with different temperatures.

[0032] Among them, thermochromic (TC) materials are functional materials whose absorption spectra change during the process of heating and cooling. They have the characteristics that the transmittance or color changes with temperature. They are generally referred to as materials that undergo stable and reversible optical changes under the action of different temperatures in the external field. In appearance, they often show reversible changes in color and transparency. Thermochromic materials undergo structural changes when stimulated by thermal energy, resulting in changes in their color. Its color change mechanism is that as the temperature rises, the vibration amplitude of the internal bonds of the molecules gradually increases until a certain temperature is reached, and structural changes occur inside the molecules, resulting in changes in its absorption and reflection spectra, thereby causing color changes. Thermochromic materials can be thermochromic materials, such as temperature-sensitive color change, photochromic, anti-counterfeiting fluorescence, liquid crystal materials, light storage materials, long-lasting aromatic materials, etc. The thermochromic material provided in this scheme can be vanadium dioxide, and the phase transition temperature can be changed by adding impurities to the vanadium dioxide, for example, by doping tungsten to reduce the phase transition temperature of vanadium dioxide to room temperature. For example, the phase transition temperature of vanadium dioxide doped with 1% tungsten by mass is 43°C, the phase transition temperature of vanadium dioxide doped with 1.5% tungsten by mass is 30°C, and the phase transition temperature of vanadium dioxide doped with 2% tungsten by mass is 20°C / 25°C.

[0033] Figure 2 A structural diagram of a wearable device provided in an embodiment of the present application, combined with Figure 1 and Figure 2 The device housing 2 and the processing module 4 provided in this solution are respectively connected to the device body 1, and the heating module 3 is connected to the device housing 2, and the processing module 4 is connected to the heating module 3. The processing module 4 provided in this solution can be used to control the temperature of the heating module 3, and the temperature of the device housing 2 connected to the heating module 3 is adjusted by controlling the temperature of the heating module 3, so that the thermochromic material on the device housing 2 changes in temperature, or remains within a set temperature range, so that the device housing 2 changes in color and / or transparency accordingly, or remains within a set color and / or transparency.

[0034] In one possible embodiment, Figure 3As shown in the circuit principle diagram of a heating module 3 provided, the heating module 3 provided in this solution includes a heating circuit 31 and a heat-conducting component 32. The heat-conducting component 32 provided in this solution can be a metal material heat-conducting component 32 with good thermal conductivity. The heat-conducting component 32 is in contact with the heating part of the heating circuit 31 to transfer the heat of the heating part in the heating circuit 31 to the heat-conducting part. In addition, a heat-conducting component 32 is provided in the device housing 2. When the heat-conducting component 32 is not actively heated, the heat-conducting component 32 can be used to quickly dissipate heat for the wearable device, thereby improving the heat dissipation performance of the system. At the same time, the device temperature can be accurately determined based on the pattern displayed on the device housing 2, and it can be accurately judged whether the device is overheated.

[0035] The heating circuit 31 is connected to the processing module 4 and the heat-conducting component 32. The processing module 4 can be used to control the temperature of the heat-conducting component 32 through the heating circuit 31, and transmit the temperature of the heating circuit 31 to the device housing 2 through the heat-conducting component 32, so that the temperature of the thermochromic material on the device housing 2 changes, or remains within a set temperature range, so that the device housing 2 changes in color and / or transparency, or remains at a set color and / or transparency. This solution uses the processing module 4 to control the temperature of the heating circuit 31, and transmits the temperature to the device housing 2 through the heat-conducting component 32, so as to accurately control the temperature of the device housing 2 and achieve a change in the appearance color of the device housing 2.

[0036] In one embodiment, Figure 3 As shown in the structural schematic diagram of the first device housing provided, the heat-conducting component 32 provided in the present solution can be arranged inside the device housing 2. For example, an interlayer cavity is provided inside the device housing 2 to accommodate the heat-conducting component 32 and surround it. The heat-conducting component 32 is provided in the interlayer cavity and surrounded by the device housing 2, so that the heat-conducting component 32 can evenly transfer heat to the device housing 2.

[0037] In one embodiment, Figure 4 As shown in the structural schematic diagram of the second device housing provided, the heat-conducting component 32 provided in this solution is arranged on the inner wall of the device housing 2 close to the device body 1. Optionally, the heat-conducting component 32 can be distributed in an annular manner on the inner wall of the device housing 2, so that the heat-conducting component 32 can more evenly transfer heat to the device housing 2. By arranging the heat-conducting component 32 on the inner wall of the device housing 2, while ensuring that the heat-conducting component 32 can normally transfer heat to the device housing 2, the configuration difficulty of the device housing 2 and the heat-conducting component 32 is reduced, the production efficiency of the wearable device is improved, and the production cost is reduced.

[0038] In one embodiment, Figure 5As shown in a schematic diagram of a heating circuit principle, the heating circuit 31 provided in this solution includes a switch component 311 and a heating resistor 312, and the heating resistor 312 is connected to the heat-conducting component 32 (for example, the heating resistor 312 is in direct contact with or fixedly connected to the heat-conducting component 32).

[0039] The switch component 311 provided in this solution is provided with a control terminal, a first connection terminal and a second connection terminal. The switch component 311 may be a MOS tube, a triode, etc. For example, when an NMOS tube is used as the switch component 311, the three control terminals, the first connection terminal and the second connection terminal of the switch component 311 are respectively a gate, a source and a drain. When an NPN triode is used as the switch component 311, the three control terminals, the first connection terminal and the second connection terminal of the switch component 311 are respectively a base, a collector and an emitter. In the figure, an NMOS tube is used as the switch component 311 as an example for description.

[0040] Among them, the control end of the switch component 311 is connected to the processing module 4, and the processing module 4 can control the connection and disconnection of the first connection end and the second connection end of the switch component 311 by sending a heating control signal (such as a PWM signal) to the control end of the switch component 311, that is, control the on and off of the switch component 311. Further, the switch end of the switch component 311 provided in this solution is connected to the power supply circuit of the heating resistor 312, for example, the second connection end of the switch component 311 is grounded, the first connection end is connected to the second connection end of the heating resistor 312, and the first connection end of the heating resistor 312 is connected to a power supply (such as a 12V power supply provided by a power module of a wearable device).

[0041] Among them, the processing module 4 can control the power supplied to the heating resistor 312 by controlling the on and off of the switch component 311, thereby controlling the heat generated by the heating resistor 312. For example, the processing module 4 sends a corresponding heating control signal to the control end of the switch component 311 according to the temperature of the change of the pattern on the device housing 2 of the wearable device, and heats the heating resistor 312 to a set temperature and maintains it, so that the device housing 2 changes and maintains the set pattern. This solution controls the operation of the heating resistor 312 through the switch component 311, accurately controls the temperature of the heat-conducting component 32, and accurately controls the pattern of the device housing 2.

[0042] In one embodiment, the present scheme provides a plurality of heat-conducting components 32 (the figure describes the arrangement of four heat-conducting components 32 as an example), and the plurality of heat-conducting components 32 are evenly arranged on the device housing 2, the heating resistors 312 correspond one to one with the heat-conducting components 32 (the heating resistors R3-R6 in the figure correspond to one heat-conducting component respectively), and each heating resistor 312 is connected to the corresponding heat-conducting component 32, that is, the temperature of each heat-conducting component 32 is controlled by a heating resistor 312, and the processing module 4 can uniformly control the operation of each switch component 311. By evenly arranging the plurality of heat-conducting components 32 on the device housing 2, the temperature of the device housing 2 can be controlled more accurately and evenly, and the pattern of the device housing 2 can be accurately controlled.

By evenly arranging the multiple heat-conducting components on the device casing, the control of the device casing temperature is more flexible, and the pattern of the device casing can be flexibly controlled at different temperatures at different positions of the device casing.

[0044] In a possible embodiment, the wearable device provided by the present solution further includes a first temperature detection module 5, and the first temperature detection module 5 is connected to the device housing 2 and the processing module 4. The first temperature detection module 5 provided by the present solution is used to detect the temperature of the device housing 2, and correspondingly, the processing module 4 can control the temperature of the heating module 3 according to the first temperature detection result output by the first temperature detection module 5.

[0045] For example, the processing module 4 detects the temperature of the device housing 2 in real time through the first temperature detection module 5 according to the first set temperature of the device housing 2 corresponding to the pattern to be displayed, and determines whether it is necessary to adjust the heating temperature of the device housing 2 according to the comparison result of the first temperature detection result and the first set temperature, and controls the heating power of the heating module 3 based on this. In this solution, the temperature of the device housing 2 is detected by the first temperature detection module 5, and the temperature of the device housing 2 is accurately controlled, so that the device housing 2 stably and accurately displays the corresponding pattern.
