The appearance of this phrase in various places in the specification does not necessarily mean the same embodiment, nor is it independent or alternative to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0024] The present application proposes a temperature control device, as shown inFigure 1 and Figure 2 , Figure 1 is one of the structural schematic diagrams of an embodiment of the temperature control device of the present application, Figure 2 is another structural schematic diagram of an embodiment of the temperature control device of the present application, as Figure 1 and Figure 2 shown, the temperature control device comprises a thermoelectric refrigeration module 11, a vibration switch module 12 and a processing module 13.

[0025] The thermoelectric refrigeration module 11 is used for thermoelectric refrigeration processing of the cooled object.

[0026] The vibration switch module 12 is used for detecting environmental vibration and outputting a vibration signal.

[0027] The processing module 13 is connected to the thermoelectric refrigeration module 11 and the vibration switch module 12 respectively, and the processing module 13 is used for receiving the vibration signal and controlling the working mode of the thermoelectric refrigeration module based on the triggering frequency of the vibration signal.

[0028] Specifically, the cooled object can specifically include but is not limited to a mobile phone or any other type of device or object that needs to be cooled.

[0029] The vibration switch module 12 can output a corresponding vibration signal according to the detected environmental vibration, for example, output a vibration signal once for each environmental vibration.

[0030] The processing module 13 can determine the current condition of the environment according to the vibration signal, so as to control the working mode of the thermoelectric refrigeration module according to the current condition, for example, according to the frequency of the received vibration signal, that is, the triggering frequency of the vibration signal. For example, when the triggering frequency is low, the thermoelectric refrigeration module is controlled to be in a low-power working mode, and when the triggering frequency is high, the thermoelectric refrigeration module is controlled to be in a high-power working mode.

[0031] The thermoelectric refrigeration module 11 can specifically refer to a TEC (ThermoElectric Cooler, semiconductor cooler). The thermoelectric refrigeration module 11 can have a refrigeration end and a heat dissipation end. For example, the temperature control device is a device in a vehicle wireless charging device, and the refrigeration end of the temperature control device can be used to be attached to the mobile phone contact end or the wireless charging end of the vehicle wireless charging device. The thermoelectric refrigeration module 11 can dissipate heat by transferring heat from the refrigeration end to the heat dissipation end to achieve thermoelectric refrigeration.

[0032] In an example, the thermoelectric refrigeration module 11 can include a thermoelectric refrigeration device and a fan. The processing module 13 is connected to the thermoelectric refrigeration device and the fan respectively, and is specifically configured to control the refrigeration power of the thermoelectric refrigeration device and the rotating speed of the fan based on the triggering frequency of the vibration signal. Wherein, the thermoelectric refrigeration device can be used to transfer the heat of the end requiring refrigeration to the heat dissipation end, and the fan can be used to accelerate the heat transfer efficiency between the heat dissipation end and the air. For example, when the triggering frequency is low, the refrigeration power of the thermoelectric refrigeration device is controlled to be low, and the rotating speed of the fan is controlled to be low, and when the triggering frequency is high, the refrigeration power of the thermoelectric refrigeration device is controlled to be high, and the rotating speed of the fan is controlled to be high.

[0033] In addition, in other examples, the thermoelectric refrigeration module 11 can also include other types of cooling devices, and the processing module 13 is specifically configured to control the working mode of the other types of cooling devices based on the triggering frequency of the vibration signal.

[0034] Assuming that the temperature control device is a vehicle-mounted device (such as a vehicle-mounted wireless charging device), when the vehicle in which the vehicle-mounted device is located moves, the vibration switch module 12 in the temperature control device can detect the vibration caused by the movement of the vehicle, so as to determine that the vehicle is moving.

[0035] At this time, first, it can be determined that due to the movement of the vehicle, the user is more likely to start the navigation function of the cooled object (such as a mobile phone), which causes the mobile phone to have a high heat power. At this time, the temperature control device can be controlled to operate at a high power based on the processing module 13, that is, the refrigeration power of the thermoelectric refrigeration device in the thermoelectric refrigeration module 11 and the rotating speed of the fan are increased to improve the heat dissipation efficiency, so as to ensure that the temperature of the cooled object is kept in a safe range and the performance of the cooled object during vehicle navigation is improved.

[0036] Based on the above manner, whether the vehicle moves can be detected by the vibration switch module 12, and then it can be determined whether the user is likely to turn on the navigation function of the cooled object, and then the dynamic control of the thermoelectric refrigeration module 11 is realized based on the detection result, so as to ensure that when the heat power of the cooled object is increased due to the navigation function, the thermoelectric refrigeration power of the thermoelectric refrigeration module 11 is also increased correspondingly, so as to reduce the possibility of the temperature of the cooled object being too high, and the temperature control effect of the temperature control device is improved.

[0037] Secondly, it can be determined that the environmental noise caused by the movement in the vehicle is high, and the temperature control device can be controlled to operate at a higher power based on the processing module 13 at this time when it is determined that the environmental noise is high, that is, the cooling power of the thermoelectric cooling element in the thermoelectric cooling module 11 and the rotating speed of the fan are increased to improve the heat dissipation efficiency. At this time, the noise caused by the cooling power of the thermoelectric cooling element and the rotating speed of the fan is relatively small due to the excessive environmental noise, so the negative impact of the noise emitted by the temperature control device 22 can be minimized while improving the temperature control effect of the temperature control device.

[0038] For example, when the temperature control device is a vehicle-mounted wireless charging device, the above-mentioned method can solve the problem of excessive temperature of the mobile phone when it is simultaneously charged wirelessly and navigated, and improve the user experience.

[0039] For example, in actual use, assuming that the temperature control device is a vehicle-mounted device (such as a vehicle-mounted wireless charging device), when the vehicle to which the vehicle-mounted device belongs is stationary, the vibration switch module 12 is turned off because no vibration is detected. At this time, in response to detecting the off state of the vibration switch module 12, the processing module 13 can control the operating voltage of the thermoelectric cooling element to be 3.6 volts, and the duty cycle of the rotating speed control signal of the fan to be 67%. At this time, the noise generated by the thermoelectric cooling module 11 is small.

[0040] When the vehicle to which the vehicle-mounted device belongs moves, the vibration switch module 12 is turned on because vibration is detected. At this time, in response to detecting the on state of the vibration switch module 12, the processing module 13 can control the operating voltage of the thermoelectric cooling element to be a target voltage, which is greater than 3.6 volts, and the duty cycle of the rotating speed control signal of the fan to be a target duty cycle, which is greater than 67%. The target voltage and the target duty cycle can be positively correlated with the on frequency of the vibration switch module 12, respectively. At this time, although the noise generated by the thermoelectric cooling module 11 is large, since the vehicle itself moves, the environmental noise caused by the shaking of the equipment in the vehicle or other reasons is large, so the noise generated by the thermoelectric cooling module 11 is relatively small, which does not cause excessive negative impact in the case of a relatively noisy environment, and also improves the temperature control effect.

[0041] Differing from the prior art, in the technical solution of the application, the temperature control device comprises a thermoelectric refrigeration module, a vibration switch module and a processing module, the thermoelectric refrigeration module is used for thermoelectric refrigeration of the cooled object, the vibration switch module is used for detecting environmental vibration and outputting a vibration signal, and the processing module is connected to the thermoelectric refrigeration module and the vibration switch module, and is used for receiving the vibration signal and controlling the working mode of the thermoelectric refrigeration module based on the triggering frequency of the vibration signal. Based on the above mode, the processing module can detect, through the vibration switch module, whether the temperature control device is subjected to vibration due to the motion of a vehicle or other reasons at the location where the temperature control device is located. If vibration occurs, it can be determined that the vehicle in which the temperature control device is located is moving. At this time, the user has a high probability of starting the navigation function of the cooled object to navigate the vehicle. The heat generation power of the cooled object will be increased. Therefore, the working mode of the thermoelectric refrigeration module can be controlled based on the triggering frequency of the vibration signal to operate at a higher power, so as to improve the efficiency of thermoelectric refrigeration, thereby realizing effective heat dissipation of the cooled object even when the heat generation power of the cooled object is high, and improving the temperature control effect of the temperature control device.

[0042] In addition, based on the above mode, the processing module can also detect, through the vibration switch module, whether the temperature control device is subjected to vibration due to the motion of a vehicle or other reasons at the location where the temperature control device is located. If vibration occurs, it can be determined that the environmental noise of the environment in which the temperature control device is located is large. At this time, the negative influence of the noise generated by each device in the thermoelectric refrigeration module is smaller than the negative influence of the environmental noise. Therefore, the working mode of the thermoelectric refrigeration module can be controlled based on the triggering frequency of the vibration signal to operate at a higher power, so as to improve the efficiency of thermoelectric refrigeration, thereby realizing the improvement of the temperature control effect of the temperature control device in the case that the noise generated by the thermoelectric refrigeration module is small.

[0043] In an embodiment, as shown in Figure 1 and Figure 2 , one end of the vibration switch module 12 is used for receiving a power voltage, the other end of the vibration switch module 12 is connected to the input end of the processing module 13, and the output end of the processing module 13 is connected to the thermoelectric refrigeration module 11.

[0044] Specifically, the vibration switch module 12 can be used to turn on when detecting that the location where the vibration switch module 12 is located is vibrating, and turn off when detecting that the location where the vibration switch module 12 is located is not vibrating, or, turn on when detecting that the location where the vibration switch module 12 is located is not vibrating, and turn off when detecting that the location where the vibration switch module 12 is located is vibrating, so that the processing module 13 can detect whether the location where the vibration switch module 12 is located is vibrating based on the vibration switch module 12, and then the processing module 13 can control the thermoelectric refrigeration based on the result of the vibration detection, for example, increase the power of the thermoelectric refrigeration module 11 when vibrating, that is, the vibration switch module 12 can detect whether the vehicle is moving, and then determine whether the user is likely to open the navigation function of the cooled object, and then realize dynamic control of the thermoelectric refrigeration module 11 based on the detection result, to ensure that the cooled object can also synchronously increase the thermoelectric refrigeration power of the thermoelectric refrigeration module 11 while increasing the heat generation power due to the navigation function, to reduce the possibility of the cooled object appearing too high temperature, and improve the temperature control effect of the temperature control device.

[0045] Optionally, as shown in Figure 1 and Figure 2 , the temperature control device further comprises a first diode D1 and a second diode D2.

[0046] The negative electrode of the first diode D1 is used to receive the power supply voltage, the other end of the vibration switch module 12 is connected to the input end of the processing module 13, the positive electrode of the first diode D1 and the negative electrode of the second diode D2 respectively, and the positive electrode of the second diode D2 is grounded.

[0047] Specifically, when the voltage at the intersection point of the positive electrode of the first diode D1 and the negative electrode of the second diode D2 is greater than the sum of the power supply voltage VCC and the conduction voltage of the first diode D1, the first diode D1 will be turned on, and when the voltage at the intersection point is less than the conduction voltage of the negative second diode D2, the second diode D2 will be turned on. Based on the above-mentioned manner, the voltage at the intersection point can be limited to a voltage range with a maximum value of the sum of the power supply voltage VCC and the conduction voltage of the first diode D1, and a minimum value of the conduction voltage of the negative second diode D2, which has the effect of limiting the voltage of the signal input to the processing module 13 and protecting the processing module 13.

[0048] Optionally, as shown in Figure 1 and Figure 2 , the temperature control device further comprises a first resistor R1 and / or a second resistor R2.

[0049] One end of the first resistor R1 is used to receive the power supply voltage, and the other end of the first resistor R1 is connected to one end of the vibration switch module 12.

[0050] One end of the second resistor R2 is connected to the other end of the vibration switch module 12, and the other end of the second resistor R2 is connected to the input end of the processing module 13.

[0051] Specifically, by arranging the first resistor R1 and / or the second resistor R2 on the circuit through which the power voltage passes the vibration switch module 12 and is input to the processing module 13, the current on the circuit can be limited when the vibration switch module 12 is turned on, thereby protecting the processing module 13.

[0052] Optionally, as shown in Figure 1 and Figure 2 , the temperature control device further includes a first capacitor C1.

[0053] One end of the first capacitor C1 is connected to one end of the vibration switch module 12, and the other end of the first capacitor C1 is grounded.

[0054] Specifically, the first capacitor C1 can be used to filter the signal corresponding to the power voltage input to the vibration switch module 12, thereby improving the stability of the power supply to the vibration switch module 12 and improving the accuracy of the vibration detection by the vibration switch module 12, thereby improving the accuracy of the temperature control device when controlling the temperature.

[0055] Optionally, as shown in Figure 1 and Figure 2 , the temperature control device further includes a second capacitor C2.

[0056] One end of the second capacitor C2 is connected to the input end of the processing module 13, and the other end of the second capacitor C2 is grounded.

[0057] Specifically, the second capacitor C2 can be used to shape the waveform of the signal input to the processing module 13, and different capacitors C2 with different capacitance values can have different shaping effects on the waveform, thereby meeting the requirements of the processing module 13 used, improving the accuracy of the vibration detection by the vibration switch module 12, and improving the accuracy of the temperature control device when controlling the temperature.

[0058] In an embodiment, the vibration switch module 12 can include a spring vibration switch.

[0059] Specifically, in an example, the vibration switch module 12 can be a spring vibration switch, which is a mechanical trigger type switch, for example, which can be triggered to turn on when a vibration occurs and to turn off when no vibration occurs.

[0060] In other examples, the vibration switch module 12 can be a ball vibration switch, a piezoelectric vibration sensor, an electronic vibration module, and other types of switch devices that can be used for vibration detection, which can be determined according to actual needs, and is not limited here.

[0061] The application also provides a vehicle-mounted device, referring to Figure 3 , Figure 3 is a structural schematic diagram of an embodiment of the vehicle-mounted device of the application, as shown in Figure 3 The vehicle-mounted device 20 comprises a power supply device 21 and a temperature control device 22, and the power supply device 21 is connected to the temperature control device 22 for power supply.

[0062] The temperature control device 22 can be the temperature control device of any one of the foregoing embodiments, which will not be described herein.

[0063] Different from the prior art, in the technical solution of the application, the temperature control device comprises a thermoelectric refrigeration module, a vibration switch module and a processing module, the thermoelectric refrigeration module is used for thermoelectric refrigeration of the cooled object, the vibration switch module is used for detecting environmental vibration and outputting a vibration signal, and the processing module is connected to the thermoelectric refrigeration module and the vibration switch module, and is used for receiving the vibration signal and controlling the working mode of the thermoelectric refrigeration module based on the triggering frequency of the vibration signal. Based on the above mode, the processing module can detect whether the temperature control device is subjected to vibration due to vehicle movement or other reasons at the location thereof through the vibration switch module. If vibration occurs, it can be determined that the vehicle in which the temperature control device is located is moving. At this time, the user has a high probability of starting the navigation function of the cooled object for vehicle navigation, and the heat power of the cooled object will be increased. Therefore, the working mode of the thermoelectric refrigeration module can be controlled based on the triggering frequency of the vibration signal to operate at a higher power, so as to improve the efficiency of thermoelectric refrigeration, so that effective heat dissipation of the cooled object can be realized even in the case that the heat power of the cooled object is high, thereby improving the temperature control effect of the temperature control device.
