Description

Technical Field

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

[0002] Current smart glasses, such as AR, XR, and MR smart glasses, generate a lot of heat in their circuit modules when they are working. Because smart glasses are designed to be lightweight and miniaturized, it is difficult to incorporate active cooling structures such as air cooling or water cooling into their structure. They often have to rely on heat sinks or thermal paste to passively cool the heat-generating circuit modules, which is inefficient and has poor heat dissipation performance. This can easily affect the stability and reliability of the smart glasses. Summary of the Invention

[0010] The control module is also used to control the Peltier module to stop working when the temperature of the heating module is less than or equal to a preset temperature threshold, based on the temperature detection signal.

[0011] Optionally, the control module includes:

[0012] Main controller;

[0013] A switching circuit, wherein the input terminal of the switching circuit is connected to the first power supply terminal, the output terminal of the switching circuit is connected to the power supply terminal of the Peltier module, and the controlled terminal of the switching circuit is electrically connected to the main controller;

[0014] The main controller is configured to, based on the temperature detection signal, control the switching circuit to open the path between the power supply terminal and the first power supply terminal of the Peltier module to enable the Peltier module to operate, or control the switching circuit to disconnect the path between the power supply terminal and the first power supply terminal of the Peltier module to enable the Peltier module to stop operating.

[0015] Optionally, the temperature detection module is disposed between the heat-generating module and the heat-absorbing surface of the Peltier module;

[0016] Alternatively, the temperature detection module and the heating module can be integrated into the same module.

[0017] Optionally, a heat-conducting medium is provided between the heat-absorbing surfaces of the heating module and the Peltier module.

[0023] The thermoelectric module is used to convert the heat released from the heat-dissipating surface of the Peltier module into a thermoelectric value and output a first voltage.

[0024] The charging module is used to convert the first voltage and output it to the battery to charge the battery.

[0025] Optionally, the thermoelectric module includes a temperature difference thermoelectric conversion module, which includes a cold surface and a hot surface arranged opposite to each other, and the hot surface of the temperature difference thermoelectric conversion module is fitted to the heat release surface of the Peltier module.

[0026] Optionally, the cold side of the thermoelectric conversion module is provided with a heat dissipation component.

[0027] Optionally, the glasses body is further provided with a heat dissipation part, and the smart glasses also include:

[0028] A heat-conducting module, one end of which is attached to the heat-dissipating surface of the Peltier module, and the other end of which is attached to the heat dissipation part; the heat-conducting module is used to conduct the heat released by the heat-dissipating surface of the Peltier module to the heat dissipation part.

[0035] The charging module is used to convert the first voltage and output it to the battery to charge the battery.

[0036] This application discloses smart glasses comprising a glasses body and a heating module disposed within the glasses body. The smart glasses also include a Peltier module, a temperature detection module, and a control module. The temperature detection module detects the temperature of the heating module and outputs a corresponding temperature detection signal. The control module controls the Peltier module to be in an active or inactive state based on the temperature detection signal, ensuring that the temperature of the heating module is less than or equal to a preset temperature threshold. Through this configuration, during the operation of the smart glasses, if the temperature of the heating module, which easily generates a large amount of heat, becomes too high, the control module will activate the Peltier module, which is attached to the surface of the heating module. This allows the heat-absorbing surface to absorb the heat generated by the heating module and release it through the heat-releasing surface, effectively reducing the temperature of the heating module. Because the Peltier module is small, can be attached to the device, and provides active heat dissipation, using a Peltier module to dissipate heat from the heating module within the smart glasses body effectively improves the heat dissipation performance of the smart glasses, thereby ensuring the stability of the smart glasses' operation.

[0050] Current smart glasses, such as AR, XR, and MR smart glasses, generate a lot of heat in their circuit modules when they are working. Because smart glasses are designed to be lightweight and miniaturized, it is difficult to incorporate active cooling structures such as air cooling or water cooling into their structure. They often have to rely on heat sinks or thermal paste to passively cool the heat-generating circuit modules, which is inefficient and has poor heat dissipation performance. This can easily affect the stability and reliability of the smart glasses.

[0051] Therefore, this application proposes a smart glasses, which includes a glasses body and a heating module 00 disposed within the glasses body. In the smart glasses, the heating module 00 can be a power module, an optomechanical module, a processor module, etc. In one embodiment of this application, reference is made to... Figure 1 and Figure 2 The smart glasses also include:

[0052] The Peltier module 10 has a heat-absorbing surface and a heat-releasing surface arranged opposite to each other. The heat-absorbing surface of the Peltier module 10 is attached to the heating module 00. The Peltier module 10 is used to absorb heat from the heat-absorbing surface and release heat from the heat-releasing surface when it is in working condition.

[0053] Temperature detection module 20, the temperature detection module 20 is used to detect the temperature of the heating module 00 and output a corresponding temperature detection signal;

[0054] Control module 30, which is electrically connected to temperature detection module 20 and Peltier module 10 respectively;

[0055] The control module 30 is used to control the Peltier module 10 to be in a working state or a stopped working state according to the temperature detection signal, so that the temperature of the heating module 00 is less than or equal to a preset temperature threshold.

[0056] In this embodiment, the Peltier module 10 can be made of a semiconductor material exhibiting the Peltier effect, such as lead telluride or Cu2Se-based materials. When the Peltier module 10 is powered on (in working condition), its heat-absorbing surface absorbs heat, thereby lowering the temperature and creating a cooling effect, while its heat-releasing surface releases heat. Therefore, the control module 30 can control whether the heating module 00 performs active cooling by controlling whether the Peltier module 10 is in working condition.

[0057] Optionally, the temperature detection module 20 can be implemented using an NTC resistive sensor, a thermocouple temperature sensor, or the like. For example, the temperature detection module 20 can be implemented using a voltage divider circuit formed by an NTC resistive sensor and a resistor with a fixed resistance value. The control module 30 can calculate the current temperature of the NTC resistor based on the voltage of the temperature detection signal output by the temperature detection module 20, the known power supply voltage, and the resistance value of the fixed resistor. Then, based on the pre-stored NTC resistance-temperature mapping table, the control module 30 can determine the current temperature of the heating module 00.

[0058] Optionally, in one embodiment, the main control module can be implemented using a main controller 31 and a power supply circuit for providing operating voltage, with the enable terminals of the main controller 31 and the power supply circuit electrically connected. The main controller 31 can be implemented using an MCU, DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), PLC, SOC (System on Chip), etc. The power supply circuit can convert the voltage of the battery 40 in the smart glasses and output an operating voltage that meets the requirements of the Peltier module 10. When the main controller 31 needs to control the Peltier module 10 to be in a working state, it will output a start signal to the enable terminal of the power supply circuit to enable the power supply circuit to start supplying power to the Peltier module 10; when the main controller 31 needs to control the Peltier module 10 to be in a stopped state, it will output a stop signal to the enable terminal of the power supply circuit to stop the power supply circuit, and the Peltier module 10 will then stop working.

[0059] Alternatively, in another embodiment, reference is made to... Figure 3The control module 30 includes: a main controller 31; and a switching circuit 32. The input terminal of the switching circuit 32 is connected to a first power supply terminal, the output terminal of the switching circuit 32 is connected to the power supply terminal of the Peltier module 10, and the controlled terminal of the switching circuit 32 is electrically connected to the main controller 31. The main controller 31 is used to control the switching circuit 32 to open the path between the power supply terminal and the first power supply terminal of the Peltier module 10 to put the Peltier module 10 into a working state, or to control the switching circuit 32 to close the path between the power supply terminal and the first power supply terminal of the Peltier module 10 to put the Peltier module 10 into a stopped working state, based on a temperature detection signal. In this embodiment, the main controller 31 can be implemented as described in the above embodiments, and the switching circuit 32 can be implemented using a switching transistor, such as an IGBT or a MOS switching transistor. The first power supply terminal is used to connect to the system voltage, which can be the power supply voltage for a certain module within the smart glasses. Thus, the Peltier module 10 can share a power module with a certain module within the smart glasses, effectively saving space within the glasses. When the main controller 31 needs to control the Peltier module 10 to be in a working state, it outputs a start signal to the controlled terminal of the switching circuit 32 to control the switching circuit 32 to open the path between the power supply terminal and the first power supply terminal of the Peltier module 10, thereby powering on the Peltier module 10 and putting it into a working state. When the main controller 31 needs to control the Peltier module 10 to be in a stopped working state, it outputs a stop signal to the controlled terminal of the switching circuit 32 to control the switching circuit 32 to disconnect the path between the power supply terminal and the first power supply terminal of the Peltier module 10, and the Peltier module 10 is then powered off and put into a stopped working state. In this way, through the above settings, the control module 30 can control the Peltier module 10 to be in a working state or a stopped working state. In the above embodiment, the main controller 31 can be a processor module in the smart glasses or a separate main controller 31.

[0060] Optionally, in one embodiment, the control module 30 is configured to control the Peltier module 10 to be in working state when the temperature of the heating module 00 is greater than a preset temperature threshold (preset by the R&D personnel) based on the temperature detection signal, and is also configured to control the Peltier module 10 to be in a stopped working state when the temperature of the heating module 00 is less than or equal to the preset temperature threshold based on the temperature detection signal.

[0061] Alternatively, in another embodiment, the control module 30 can also determine, based on the temperature detection signal, that although the temperature of the heating module 00 is less than the preset temperature threshold, the rate of change has reached the preset rate of change (preset by the R&D personnel). In this case, the control module 30 will also control the Peltier module 10 to be in working state so as to reduce the temperature of the heating module 00 in advance.

[0062] In summary, through the above-described configuration, during the operation of the smart glasses, if the temperature of the heat-generating module 00, which is prone to generating a large amount of heat, becomes too high, the control module 30 will activate the Peltier module 10, which is attached to the surface of the heat-generating module 00. This allows the heat-absorbing surface to absorb the heat generated by the heat-generating module 00 and release it from the heat-releasing surface, thereby effectively reducing the temperature of the heat-generating module 00. Since the Peltier module 10 is small in size, can be attached to the device, and provides active heat dissipation, using the Peltier module 10 to dissipate heat from the heat-generating module 00 within the smart glasses effectively improves the heat dissipation performance of the smart glasses, thus ensuring the stability of the smart glasses' operation.

[0063] Optionally, refer to Figure 1 In one embodiment of this application, the temperature detection module 20 is disposed between the heat-generating module 00 and the heat-absorbing surface of the Peltier module 10, thereby effectively improving the accuracy of temperature detection. Optionally, in another embodiment, the temperature detection module 20 and the heat-generating module 00 are integrated into the same module. In other words, the heat-generating module 00 has its own temperature detection function and is connected to the control module 30 to output the detection result to the control module 30.

[0064] Optionally, in one embodiment, a thermally conductive medium is disposed between the heat-absorbing surfaces of the heating module 00 and the Peltier module 10. In this embodiment, the thermally conductive medium can be implemented using thermal grease, thermal paste, or thermal pads, etc. This improves the heat absorption efficiency of the Peltier module 10's heat-absorbing surface during operation, thereby increasing the heat conduction rate and the temperature drop rate of the heating module 00, and further enhancing the reliability and stability of the smart glasses' operation.

[0065] It is important to understand that while the Peltier module 10 absorbs heat generated by the heating module 00 on its heat-absorbing surface to reduce the temperature of the heating module 00, it also releases the heat through its heat-releasing surface. Because the smart glasses are relatively small, if the heat released from the heat-releasing surface is not quickly conducted to the outside of the smart glasses or is dissipated, the overall temperature inside the smart glasses housing may rise over time, potentially affecting the reliability and stability of other internal components.

[0066] Therefore, optionally, in one embodiment of the application, reference is made to Figure 4 and Figure 5 The smart glasses also include:

[0067] Battery 40;

[0068] A charging module 50 is electrically connected to the battery 40.

[0069] Thermoelectric module 60 is attached to the heat-dissipating surface of Peltier module 10 and is electrically connected to charging module 50.

[0070] The thermoelectric module 60 is used to convert the heat released from the heat-dissipating surface of the Peltier module 10 into a thermoelectric value and output a first voltage.

[0071] The charging module 50 is used to convert the first voltage and output it to the battery 40 to charge the battery 40.

[0072] In this embodiment, the charging module 50 can be implemented using a charging management chip. The charging management chip can receive a first voltage from the thermoelectric module 60 and charge the battery 40. Furthermore, the charging management chip can also allocate power according to the current output power of the thermoelectric module 60. After satisfying the power supply needs of other devices in the smart glasses, the remaining power can be output to the battery 40 to charge the battery 40.

[0073] Optionally, the thermoelectric module 60 includes a thermoelectric conversion module with a cold surface and a hot surface arranged opposite each other. The hot surface of the thermoelectric conversion module is bonded to the heat-dissipating surface of the Peltier module 10. The thermoelectric conversion module can be made of a material exhibiting the Seebeck effect, such as Bi2Te3-based thermoelectric materials, Skutterudite thermoelectric materials, oxide thermoelectric materials, etc. The specific material can be selected by researchers during development based on the temperature of the heating module 00. With the hot surface of the thermoelectric conversion module bonded to the heat-dissipating surface of the Peltier module 10, when the heating module 00 generates heat and the Peltier module 10 starts working in the above embodiment, the heat-dissipating surface of the Peltier module 10 releases heat, thereby increasing the temperature of the hot surface of the thermoelectric conversion module. This creates a temperature difference between the hot and cold surfaces of the thermoelectric conversion module, resulting in the output of a first voltage. Furthermore, in one embodiment, in order to improve the output power of the thermoelectric conversion module and thus achieve more efficient utilization of the heat generated by the heating module 00, a heat dissipation component is provided on the cold side of the thermoelectric conversion module, thereby increasing the temperature difference between the cold and hot sides of the thermoelectric conversion module and thus improving its output power.

[0074] Alternatively, in another embodiment, the thermoelectric conversion module can also be implemented using a thermophotovoltaic module. The thermophotovoltaic module includes a thermal emitter and a group of 40 thermophotovoltaic cells. The thermophotovoltaic conversion module can generate corresponding thermal radiation (converting thermal energy into light energy) based on the heat released from the heat-dissipating surface of the Peltier module 10 and irradiate the group of 40 photovoltaic cells. The group of 40 photovoltaic cells converts the received thermal radiation into electrical energy and stores it (light energy converted into electrical energy). Then, the group of 40 photovoltaic cells outputs a first voltage to charge the battery 40 via the charging module 50.

[0075] In summary, the above-mentioned design not only improves the heat dissipation of the Peltier module 10 from accumulating inside the smart glasses, but also allows the heat to be recovered and converted into electrical energy to charge the battery 40 in the smart glasses, thereby effectively improving the battery life of the smart glasses.

[0076] Optionally, in another embodiment of this application, reference is made to... Figure 6 The glasses body is also provided with a heat dissipation part 80, and the smart glasses also include:

[0077] A heat-conducting module 70 is provided, with one end of which is attached to the heat-dissipating surface of the Peltier module 10 and the other end of which is attached to the heat dissipation part 80; the heat-conducting module 70 is used to conduct the heat released by the heat-dissipating surface of the Peltier module 10 to the heat dissipation part 80.

[0078] In this embodiment, the thermally conductive module 70 can be implemented using graphene thermally conductive sheets / films, thermally conductive silicone, heat pipe modules, etc.

[0079] A heat dissipation section 80 can be provided on the main body of the glasses for heat dissipation. The heat dissipation section 80 is equipped with a heat dissipation device that contacts the outside of the main body of the glasses, thereby conducting heat from inside the smart glasses to the air. Optionally, since some structures of the smart glasses, such as the temples, frame, bridge, and nose bridge, will come into contact with the user's skin during use, in order to prevent internal heat from being conducted to the user's skin through the heat dissipation section 80, in one embodiment, the main body of the glasses includes a frame and temples respectively disposed on both sides of the frame. The frame includes a front part and side parts disposed on both sides of the front part; the heat dissipation section 80 is disposed in the side parts. Since the side parts of the frame generally do not come into contact with the user's skin, when the heat dissipation section 80 conducts heat from inside the smart glasses to the air, it will not have a significant impact on the user, effectively improving the user experience.

[0080] In summary, the above-mentioned settings can effectively improve the accumulation of heat released from the heat-dissipating surface of the Peltier module 10 within the smart glasses, thereby further enhancing the stability of the smart glasses and their internal circuit modules.

[0081] Furthermore, based on the embodiment where a heat-conducting module 70 is provided in the glasses body, the smart glasses also include: a battery 40; a charging module 50, wherein the charging module 50 is electrically connected to the battery 40;

[0082] A thermoelectric module 60 is attached to the heat-conducting module 70 and electrically connected to the charging module 50. The thermoelectric module 60 is used to convert the heat conducted by the heat-conducting module 70 into a thermoelectric value and output a first voltage. The charging module 50 is used to convert the first voltage into a voltage value and output it to the battery 40 to charge the battery 40.

[0083] In this embodiment, the specific embodiments of the thermoelectric module 60 and the charging module 50 can be referred to the contents of the above embodiments, and will not be repeated here. In this way, not only can the heat released by the heat-dissipating surface of the Peltier module 10 be improved from accumulating inside the smart glasses, but the heat can also be recovered and converted into electrical energy to charge the battery 40 in the smart glasses, thereby effectively improving the battery life of the smart glasses.

[0084] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
