Technical Field

[0002] Embodiments of the present application relate to the field of electronic technology, and more particularly, to a heat dissipation method and electronic equipment. Background Art

[0003] Currently, electronic devices generally generate heat when used by users, especially in high-power scenarios such as playing games or watching videos. High temperatures can affect the performance of electronic devices.

[0004] In order to maintain good performance of electronic devices, heat dissipation is generally performed on the electronic devices. For example, a heat spreader or a graphite sheet can be used for heat dissipation. However, this solution relies on the back panel of the electronic device for heat dissipation and has a poor heat dissipation effect.

[0005] Therefore, how to efficiently dissipate heat from electronic equipment has become a technical problem that needs to be solved.

[0006] Summary of the Invention

[0007] The present application provides a heat dissipation method and an electronic device, so as to efficiently dissipate heat from the electronic device.

[0008] In a first aspect, a heat dissipation method is provided, which is applied to a first electronic device. The method includes: when the first electronic device is worn by a second electronic device, obtaining the temperature of the first electronic device; when the temperature of the first electronic device is greater than or equal to a first preset value, supplying power to the second electronic device and controlling the second electronic device to drive a heat dissipation medium to move at a first power.

[0009] Based on the embodiment of the present application, when a second electronic device is worn on a first electronic device, the temperature of the first electronic device can be obtained. When the temperature of the first electronic device is greater than or equal to a first preset value, power is supplied to the second electronic device and the second electronic device is controlled to drive the heat dissipation medium to move.

[0010] In this way, when the temperature is high, the first electronic device can accurately control the second electronic device to drive the heat dissipation medium to move to dissipate heat for the first electronic device. Since the second electronic device is worn on the first electronic device, when the heat dissipation medium in the second electronic device moves, it can quickly take away the heat on the back panel of the first electronic device, thereby achieving efficient heat dissipation of the first electronic device.

[0011] In combination with the first aspect, in an implementation of the first aspect, controlling the second electronic device to drive the heat dissipation medium to move with the first power includes: sending first indication information to the second electronic device, where the first indication information is used to instruct the second electronic device to drive the heat dissipation medium to move according to the first power.

[0012] Based on the embodiment of the present application, the first electronic device can send a first indication message to the second electronic device to instruct the second electronic device to drive the heat dissipation medium to move according to the first power, so that the first electronic device can accurately control the power of the second electronic device through the first indication message, thereby accurately controlling the heat dissipation of the first electronic device.

[0013] In other embodiments, the first electronic device may not send the first indication information to the second electronic device, but directly supply power to the second electronic device at the first power.

[0014] In combination with the first aspect, in an implementation of the first aspect, the method further includes: after a first preset time period, controlling the second electronic device to drive the heat dissipation medium to move with a second power, wherein the second power is less than the first power.

[0015] This application does not limit the specific value of the first preset time length. For example, the first preset time length can be 1 minute or 30 seconds.

[0016] According to the embodiment of the present application, since the second electronic device initially requires a large amount of power to drive the heat dissipation medium, and once the heat dissipation medium begins to flow, a smaller amount of power is required to maintain the flow. Therefore, after the first preset time period, the first electronic device controls the second electronic device to operate at the second power, thereby saving power consumption of the first electronic device.

[0017] In combination with the first aspect, in an implementation of the first aspect, the method further includes: when the temperature of the first electronic device is greater than or equal to a second preset value and less than the first preset value, sending second indication information to the second electronic device, wherein the second indication information is used to instruct the second electronic device to drive the heat dissipation medium to move according to a third power, wherein the third power is less than the first power.

[0018] Based on the embodiment of the present application, after the second electronic device starts working to dissipate heat for the first electronic device, the temperature of the first electronic device will decrease accordingly. When the temperature of the first electronic device is greater than or equal to the second preset value and less than the first preset value, second indication information can be sent to the second electronic device to instruct the second electronic device to drive the heat dissipation medium to move according to a third power that is less than the first power, thereby reducing the power consumption of the first electronic device while dissipating heat.

[0019] In combination with the first aspect, in an implementation manner of the first aspect, the method further includes: when the temperature of the first electronic device is lower than the second preset value, the first electronic device stops supplying power to the second electronic device.

[0020] Based on the embodiment of the present application, as the second electronic device operates, the temperature of the first electronic device decreases. When the temperature of the first electronic device is less than a second preset value, the first electronic device can stop supplying power to the second electronic device to stop heat dissipation, thereby avoiding the situation where the second electronic device is still operating when the temperature of the first electronic device is already low.

[0021] In combination with the first aspect, in an implementation manner of the first aspect, the method further includes: when the first electronic device is in the first state, the first electronic device stops supplying power to the second electronic device.

[0022] Exemplarily, the first state may include but is not limited to: a voice call state, a video call state, a recording state, and a low battery state.

[0023] According to the embodiment of the present application, since the second electronic device relies on the power supply of the first electronic device to operate, and the second electronic device generates a certain amount of vibration when operating, when the first electronic device is in the first state, the first electronic device can stop supplying power to the second electronic device, thereby reducing the impact on the current business of the first electronic device or saving the power consumption of the first electronic device.

[0024] In combination with the first aspect, in an implementation of the first aspect, before controlling the second electronic device to drive the heat dissipation medium to move with the first power, the method further includes: obtaining device information of the second electronic device; and determining that the second electronic device is a heat dissipation device through the device information.

[0025] Based on the embodiment of the present application, the first electronic device can also obtain the device information of the second electronic device, and further determine that the second electronic device is a heat dissipation device based on the device information. This technical solution is beneficial for the first electronic device to determine the device type of the second electronic device.

[0026] In combination with the first aspect, in an implementation of the first aspect, the method further includes: when the first electronic device is worn with the second electronic device for the first time, controlling the second electronic device to drive the heat dissipation medium to move for a second preset time period; when the first electronic device is not worn with the second electronic device for the first time, the first electronic device stops supplying power to the second electronic device.

[0027] Based on the embodiment of the present application, when the first electronic device is worn with the second electronic device for the first time, the second electronic device can be controlled to work for a second preset time period to show the user the heat dissipation effect of the second electronic device on the first electronic device; when the first electronic device is not worn with the second electronic device for the first time, the first electronic device stops supplying power to the second electronic device to save power consumption.

[0028] In combination with the first aspect, in an implementation of the first aspect, before supplying power to the second electronic device, the method further includes: determining, by using a Hall element, that the first electronic device is wearing the second electronic device.

[0029] Based on the embodiment of the present application, the first electronic device can conveniently determine whether the second electronic device is being worn through a Hall element.

[0030] In combination with the first aspect, in an implementation manner of the first aspect, the method further includes: the first electronic device supplies power to the second electronic device or stops supplying power to the second electronic device according to a user operation.

[0031] Based on the embodiment of the present application, the first electronic device can also supply power to the second electronic device or stop supplying power to the second electronic device according to the user's operation. In this way, the user can also independently decide whether to let the second electronic device dissipate heat for the first electronic device.

[0032] In combination with the first aspect, in an implementation of the first aspect, supplying power to the second electronic device includes: supplying power to the second electronic device in a wireless reverse charging manner.

[0033] Based on the embodiment of the present application, the first electronic device can have a wireless reverse charging function, so that it can conveniently power the second electronic device that is worn.

[0034] In other examples, the first electronic device may also supply power to the second electronic device in a wired manner, which is not limited in the embodiment of the present application.

[0035] In a second aspect, a heat dissipation device is provided. The method is applied to a second electronic device, and the method includes: receiving power from a first electronic device; and driving a heat dissipation medium to move with a first power.

[0036] Based on the embodiment of the present application, the second electronic device drives the heat dissipation medium to move with the first power according to the power supply of the first electronic device, thereby dissipating heat for the first electronic device according to the power supply of the first electronic device.

[0037] In combination with the second aspect, in an implementation of the second aspect, driving the heat dissipation medium to move with the first power includes: receiving first indication information sent by the first electronic device; and driving the heat dissipation medium to move according to the first power based on the first indication information.

[0038] Based on the embodiment of the present application, the second electronic device can receive the first instruction information sent by the first electronic device and drive the heat dissipation medium to move at the first power according to the first instruction information. In this way, the first electronic device can accurately control the power of the second electronic device.

[0039] In combination with the second aspect, in an implementation manner of the second aspect, the method further includes: after a first preset time period, driving the heat dissipation medium to move according to a second power, wherein the second power is less than the first power.

[0040] Based on the embodiment of the present application, after the heat dissipation medium starts to flow, the required power is relatively small. At this time, the second electronic device can drive the heat dissipation medium to move according to the second power, thereby saving power consumption.

[0041] In combination with the second aspect, in an implementation of the second aspect, the method further includes: receiving second indication information sent by the first electronic device; driving the heat dissipation medium to move according to a third power based on the second indication information, wherein the third power is less than the first power.

[0114] Currently, electronic devices generally generate heat when used by users, especially in high-power scenarios such as playing games or watching videos. High temperatures can affect the performance of electronic devices.

[0115] In order to maintain good performance of electronic devices, heat dissipation is generally performed on the electronic devices. For example, a heat spreader or a graphite sheet can be used for heat dissipation. However, this solution relies on the back panel of the electronic device for natural heat dissipation, and the heat dissipation effect is poor.

[0116] In view of this, the present application provides a heat dissipation method and electronic device. In this technical solution, when the electronic device is wearing a heat dissipation device, when it is determined that the temperature of the electronic device is greater than a preset value, the heat dissipation device can be controlled to drive the heat dissipation medium to move, thereby efficiently dissipating heat for the electronic device.

As shown in FIG3 , the heat dissipation device 200 may include at least a sensor module 210 , a power module 220 , a wireless communication module 230 , and a heat dissipation medium 240 .

[0118] Exemplarily, the heat dissipation device 200 may be a heat dissipation shell, which may be worn on an electronic device such as a mobile phone or a tablet, and may dissipate heat from the electronic device through instructions from the electronic device.

[0119] For example, the sensor module 210 may include a magnetic sensor, such as a hall element. The sensor module 210 may be used by an electronic device to determine whether the heat dissipation device 200 is worn.

[0120] In some embodiments, the wireless communication module 230 can be used to support wireless power supply for the heat dissipation device 200, and the power module 220 can drive the heat dissipation medium to move according to the power supply of the electronic device. For example, the wireless communication module 230 may include a receiving coil, and the electronic device wearing the heat dissipation device 200 has a wireless reverse charging function. When the electronic device wirelessly powers the heat dissipation device, the electronic device can transmit the power outward through the transmitting coil, and the receiving coil in the heat dissipation device senses the corresponding magnetic field and converts it into an induced voltage. After rectification, a DC power supply is obtained, and the DC power supply can act on the power module 220. The power module 220 can drive the heat dissipation medium to move to dissipate heat for the electronic device.

[0121] It should be understood that the wireless reverse charging may also be referred to as wireless reverse charging, reverse charging, etc.

[0122] In some embodiments, the electronic device can adjust the power of the power module 220 by wirelessly powering the heat dissipation device 200, thereby adjusting the speed of the heat dissipation medium. Alternatively, when supplying power to the heat dissipation device 200, the electronic device can send instruction information to the heat dissipation device 200, instructing the heat dissipation device to drive the heat dissipation medium at different power levels, thereby achieving the purpose of accurately controlling the temperature of the electronic device.

[0123] The power module 220 may be a micro pump, which can move the heat dissipation medium.

[0124] The heat dissipation medium 240 may be a liquid cooling medium, for example, the liquid cooling medium may include water, fluorinated liquid, mineral oil, etc., and the specific content of the liquid cooling medium is not limited in the embodiment of the present application. The heat dissipation medium may also be a liquid-gas mixture, etc.

[0125] In some embodiments, the heat dissipation medium 240 in the heat dissipation device 200 can be replaced by a fan, and the power module 220 can control the movement of the fan upon receiving a command from the electronic device to achieve the purpose of dissipating heat for the electronic device. Alternatively, the heat dissipation device 200 can include both the heat dissipation medium 240 and the fan, and the power module 220 can drive the heat dissipation medium and control the movement of the fan upon receiving a command from the electronic device, thereby achieving the purpose of quickly dissipating heat for the electronic device.

[0126] FIG4 is a schematic diagram of the architecture of an electronic device provided in an embodiment of the present application. As shown in FIG4 , the electronic device 300 may include at least a detection module 310 , an identification module 320 , and a control module 330 .

[0127] The detection module 310 can be used to detect whether the heat dissipation device 200 is in a wearable state. For example, the detection module 310 can be used to receive data from the sensor module 210 (such as hall components, etc.) of the heat dissipation device 200 and determine whether the heat dissipation device is in a wearable state based on the data.

[0128] In some embodiments, when the electronic device 300 is not wearing the heat dissipation device 200, the heat dissipation device 200 is worn on the electronic device 300. Taking the electronic device 300 including the hall component 1 and the sensor module 210 as an example, the hall component generally includes two output pins, which are used to output the magnetic north (north, N) pole proximity signal and the magnetic south (south, S) pole proximity signal respectively. When both output pins do not output a signal, the default output level is a high level; when both output pins output a signal, the output level is a low level. The detection module 310 can determine whether the heat dissipation device 200 is worn by sensing the changes in the output levels of the two output pins of the hall component 1 in the electronic device 300. For example, when the electronic device 300 is not wearing the heat dissipation device 200, the hall component 1 does not sense the change in the external magnetic field, and the levels output by the two output pins of the hall component 1 are high levels. The output pins of the hall component 1 are connected to the general-purpose input / output (GPIO) pins of the detection module 310, so that the detection module 310 can obtain the high-level signal, thereby determining that the electronic device 300 is not wearing the heat dissipation device 200; when the electronic device 300 is wearing the heat dissipation device 200, the hall component 1 will sense the magnetic field of the hall component 2, and the output pins of the hall component 1 may output an N-pole proximity signal or an S-pole proximity signal, and its output level is low. The detection module 310 can obtain the low-level signal, thereby determining that the electronic device 300 is wearing the heat dissipation device 200.

[0129] In some embodiments, when the electronic device 300 is wearing the heat dissipation device 200 and is in the off state, when the electronic device 300 changes from the off state to the on state, at this time, the detection module 310 of the electronic device 300 can also determine that the heat dissipation device 200 is in the wearing state through the low-level signal output by the output pin of the hall element 1.

[0130] In the embodiment of the present application, when the detection module 310 detects that the heat dissipation device 200 is in the worn state, the electronic device 300 can supply power to the heat dissipation device 200. For example, the electronic device 300 can have a wireless reverse charging function, so that the heat dissipation device 200 can be powered by the wireless reverse charging function.

[0131] The identification module 320 can be used to obtain device information of the heat dissipation device 200 through a wireless charging protocol (e.g., Qi protocol). The device information may include the product serial number, product type, configuration information, etc. of the heat dissipation device. Thus, the identification module 320 can determine whether the heat dissipation device 200 is a heat dissipation device based on the device information.

[0132] When the identification module 320 identifies the heat dissipation device 200 as a heat dissipation device, the control module 330 can determine whether to send an instruction to the heat dissipation device 200 according to the temperature of the electronic device 300 to enable the heat dissipation device 200 to work and dissipate heat for the electronic device 300.

[0133] In some embodiments, when the temperature of the electronic device is greater than a preset value, the control module 330 can control the electronic device 300 to send indication information to the heat dissipation device 200 through the wireless charging protocol to instruct the heat dissipation device 200 to work; the heat dissipation device 200 can drive the heat dissipation medium to move according to the indication information to achieve heat dissipation for the electronic device 300.

[0134] In some embodiments, when the temperature of the electronic device is greater than a preset value, the control module 330 can control the electronic device 300 to supply power to the heat dissipation device 200 through the wireless charging protocol, so that the heat dissipation device 200 can drive the heat dissipation medium to move, thereby achieving heat dissipation for the electronic device 300.

[0135] In other examples, the detection module 310 , the identification module 320 , and the control module 330 may be functional modules in the processor 110 mentioned above.

[0136] In an embodiment of the present application, an electronic device can determine whether a heat dissipation device is being worn. If the heat dissipation device is worn, and if the temperature of the electronic device is greater than a preset value, the device controls the heat dissipation device to operate, thereby driving the heat dissipation medium to dissipate heat from the electronic device. This technical solution can detect the temperature of the electronic device in real time and, when the temperature is high, control the heat dissipation device to operate in real time to dissipate heat from the electronic device, thereby achieving better heat dissipation for the electronic device.

[0137] The heat dissipation method in this application will be described in detail below with reference to FIG. 5 to FIG. 8 .

[0138] In the embodiment of the present application, the first electronic device may be a heat-dissipating device, such as a mobile phone, a tablet, etc., and the second electronic device may be a heat-dissipating device, such as a heat-dissipating mobile phone case.

[0139] For example, FIG5 is a schematic interactive diagram of a heat dissipation method provided by an embodiment of the present application. As shown in FIG5 , the method 400 may include steps 410 to 460 .

[0140] 410 , the first electronic device determines whether the first electronic device is worn by the second electronic device.

[0141] Exemplarily, both the first electronic device and the second electronic device may include hall components. The first electronic device may determine whether the first electronic device is wearing the second electronic device by determining the hall components. For details, please refer to the relevant description in the previous text. For the sake of brevity, it will not be repeated here.

[0142] 420. When it is determined that the first electronic device is worn by the second electronic device, the first electronic device supplies power to the second electronic device.

[0143] In some embodiments, the first electronic device has a wireless reverse charging function, so that the first electronic device can supply power to the second electronic device through the wireless reverse charging function.

[0144] In some embodiments, the first electronic device can also enable a wireless reverse charging function based on a user's operation to supply power to the second electronic device. For example, the battery management display interface of the first electronic device can include an on / off function button for the wireless reverse charging function, and the user can control the first electronic device to turn on or off the wireless reverse charging function by clicking the on / off function button.

[0145] In some implementations, the first electronic device may also supply power to the second electronic device in other ways, which are not limited in this embodiment of the present application. For example, the first electronic device may also supply power to the second electronic device in a wired manner.

[0146] 430. The first electronic device obtains device information of the second electronic device.

[0147] In some embodiments, when a first electronic device is powered by a second electronic device via a wireless reverse charging function, the first electronic device can obtain device information of the second electronic device via a wireless charging protocol. The device information may include one or more of the following information: the product serial number, product type, configuration information, and media access control (MAC) address of the second electronic device.

[0148] For example, the first electronic device may send a request message to the second electronic device. After receiving the request message, the second electronic device sends the device information of the second electronic device to the first electronic device, so that the first electronic device can obtain the device information of the second electronic device.

[0149] For another example, after the first electronic device wirelessly supplies power to the second electronic device, the second electronic device may actively send its device information to the first electronic device.

[0150] 440. The first electronic device determines, based on the device information of the second electronic device, that the second electronic device is a heat dissipation device.

[0151] After obtaining the device information of the second electronic device, the first electronic device may further determine that the second electronic device is a heat dissipation device based on the device information.

[0152] At 450, upon determining that the temperature of the first electronic device is greater than or equal to a preset value A, the first electronic device sends instruction information A to the second electronic device, where the instruction information A is used to instruct the second electronic device to drive the heat dissipation medium to move. Accordingly, the second electronic device receives the instruction information A.

[0153] The first electronic device can detect the temperature of the first electronic device in real time and, when determining that the temperature of the first electronic device is greater than or equal to a preset value A, send instruction information A to the second electronic device to instruct the second electronic device to drive the heat dissipation medium to move. Alternatively, the instruction information A can also be understood as instructing the second electronic device to operate.

[0154] The embodiment of the present application does not limit the specific numerical value of the preset value A. For example, the preset value A can be 40 degrees or 50 degrees.

[0155] In other embodiments, after the first electronic device determines that the second electronic device is a heat dissipation device, if the temperature of the first electronic device is less than a preset value A, the first electronic device may stop supplying power to the second electronic device to save power consumption of the first electronic device. Subsequently, if it is determined that the temperature of the first electronic device is greater than the preset value A, the first electronic device may resume supplying power to the second electronic device to enable the second electronic device to operate.

[0156] 460 , the second electronic device drives the heat dissipation medium to move according to the instruction information A.

[0157] After receiving the indication information A, the second electronic device can drive the heat dissipation medium to move according to the indication information A. Since the second electronic device is worn on the first electronic device, the second electronic device can take away the heat on the back panel of the first electronic device by driving the heat dissipation medium to move, thereby accelerating the heat dissipation speed of the back panel of the first electronic device and improving the heat dissipation effect of the first electronic device.

[0158] In other examples, since the second electronic device requires a large amount of power when it starts to drive the heat dissipation medium to move, but the required power will decrease after the heat dissipation medium flows, in order to reduce the power consumption of the first electronic device, the first electronic device can reduce the power supplied to the second electronic device after supplying power to the second electronic device for a preset time period T1. For example, the first electronic device can reduce the duty cycle of wireless power supply to the second electronic device after supplying power to the second electronic device for a preset time period T1 to reduce the power supplied to the second electronic device. For example, at a fixed power supply frequency, the first electronic device can reduce the power supply duration within each cycle, thereby reducing the duty cycle of wireless power supply to the second electronic device to reduce the power supplied to the second electronic device. In this way, the first electronic device can reduce the power consumption of the first electronic device while driving the second electronic device to work.

[0159] This application does not limit the specific value of the preset time length T1. For example, the preset time length T1 can be 5 seconds or 8 seconds.

[0160] It should be understood that the embodiments of the present application do not limit the specific execution order of steps 410-460. In other examples, some steps of steps 410-460 may not be executed or replaced by other steps. For example, the first electronic device may also determine whether the second electronic device is worn when it is determined that the temperature is greater than or equal to the preset value A, and may supply power to the second electronic device and control the second electronic device to drive the heat dissipation medium to move to dissipate heat for the first electronic device when it is determined that the second electronic device is worn.

[0161] In an embodiment of the present application, the first electronic device can determine whether the second electronic device is in a wearable state, and when it is determined that the second electronic device is in a wearable state, when it is determined that the temperature of the first electronic device is greater than a preset value A, it sends an indication information to the second electronic device to instruct the second electronic device to drive the heat dissipation medium to move, so that the second electronic device dissipates heat for the first electronic device.

[0162] In addition, this technical solution can detect the temperature of the first electronic device in real time, and when the temperature is high, control the second electronic device to work in real time to dissipate heat for the first electronic device, thereby improving the heat dissipation effect of the first electronic device.

[0163] In other examples, after step 440, the method 400 may further include:

[0164] 445 , the first electronic device determines whether it is the first time to wear the second electronic device.

[0165] In some embodiments, when the first electronic device determines that the second electronic device is being worn for the first time, it can send instruction information A1 to the second electronic device. Instruction information A1 can be used to instruct the second electronic device to operate for a preset duration T2. ​​In this way, the first electronic device can demonstrate to the user the effect of controlling the heat dissipation of the second electronic device.

[0166] Afterwards, the first electronic device can mark the second electronic device so that the first electronic device can determine that it is not the first time the second electronic device is worn next time, without showing the user the effect of the first electronic device controlling the second electronic device to dissipate heat.

[0167] The embodiment of the present application does not limit the specific duration of the preset duration T2. ​​For example, the preset duration T2 can be 2.5 minutes or 1 minute.

[0168] In some embodiments, when the first electronic device determines based on the tag information that the second electronic device is not being worn for the first time, if the temperature of the first electronic device is lower than a preset value A, the first electronic device may stop supplying power to the second electronic device. Alternatively, if the temperature of the first electronic device is lower than the preset value A, the first electronic device may supply power to the second electronic device but may not send an operation instruction to the second electronic device.

[0169] FIG6 is a schematic interactive diagram of another heat dissipation method provided by an embodiment of the present application. As shown in FIG6 , the method 500 may include steps 510 to 590 .

[0170] 510 , the first electronic device determines whether the first electronic device is worn by the second electronic device.

[0171] 520. When it is determined that the first electronic device is worn by the second electronic device, the first electronic device supplies power to the second electronic device.

[0172] 530. The first electronic device obtains device information of the second electronic device.

[0173] 540. The first electronic device determines, based on the device information of the second electronic device, that the second electronic device is a heat dissipation device.

[0174] It should be understood that steps 510 to 540 can refer to the relevant descriptions of steps 410 to 440 in the previous text, and for the sake of brevity, they are not repeated here.

[0175] At step 550 , upon determining that the temperature of the first electronic device is greater than or equal to a preset value B, the first electronic device sends instruction information B to the second electronic device. The instruction information B is used to instruct the second electronic device to drive the heat dissipation medium to move according to the power B. Accordingly, the second electronic device receives the instruction information B.

[0176] In some embodiments, the first electronic device can detect the temperature in real time, and when it is determined that the temperature of the first electronic device is greater than or equal to a preset value B, it sends indication information B to the second electronic device. The indication information B can be used to instruct the second electronic device to drive the heat dissipation medium to move according to power B.

[0177] In other embodiments, after the first electronic device determines that the second electronic device is a heat dissipation device, if the temperature of the first electronic device is less than a preset value B, the first electronic device may stop supplying power to the second electronic device to save power consumption of the first electronic device. Subsequently, when it is determined that the temperature of the first electronic device is greater than or equal to the preset value B, the first electronic device may resume supplying power to the second electronic device, allowing the second electronic device to operate at power B.

[0178] 560. The second electronic device drives the heat dissipation medium to move according to the instruction information B and the power B.

[0179] For example, the second electronic device can drive the heat dissipation medium to move at a speed of V1 under power B.

[0180] At step 570, when the first electronic device determines that the temperature of the first electronic device is greater than or equal to a preset value C and less than a preset value B, the first electronic device sends instruction information C to the second electronic device. The instruction information C is used to instruct the second electronic device to drive the heat dissipation medium to move according to the power C. In response, the second electronic device receives the instruction information C.

[0181] It should be understood that as the second electronic device operates, the heat dissipation medium is constantly in motion, dissipating heat for the first electronic device. After the second electronic device operates for a period of time, the temperature of the first electronic device will decrease. When it is determined that the temperature of the first electronic device is greater than or equal to a preset value C and less than a preset value B, instruction information C can be sent to the second electronic device to instruct the second electronic device to drive the heat dissipation medium to move according to power C. Power C can be less than power B, thereby saving power consumption of the first electronic device.

[0182] In the embodiment of the present application, the preset value B is greater than the preset value C. For example, the preset value B is 50 degrees and the preset value C is 40 degrees; or, the preset value B is 40 degrees and the preset value C is 30 degrees. The embodiment of the present application does not limit the specific values ​​of the preset value B and the preset value C.

[0183] In other examples, when it is determined that the temperature of the first electronic device is greater than or equal to a preset value C and less than a preset value B, the first electronic device can reduce the power supplied to the second electronic device from power B to power C, thereby saving power consumption of the first electronic device.

[0184] 580. The second electronic device drives the heat dissipation medium to move according to the instruction information C and the power C.

[0185] For example, the second electronic device can drive the heat dissipation medium to move at a speed of V2 under power C, where V2 is less than V1.

[0186] 590. When it is determined that the temperature of the first electronic device is less than a preset value C, the first electronic device stops supplying power to the second electronic device.

[0187] It should be understood that as the second electronic device operates, the temperature of the first electronic device will continue to decrease. When it is determined that the temperature of the first electronic device is less than a preset value C, the first electronic device can stop supplying power to the second electronic device. Since the temperature of the first electronic device has already decreased, the second electronic device can be controlled to stop operating to save power consumption of the first electronic device.

[0188] In an embodiment of the present application, the first electronic device can determine whether the second electronic device is in a worn state, and when it is determined that the second electronic device is in a worn state, when it is determined that the temperature of the first electronic device is high, it sends an indication message to the second electronic device to instruct the second electronic device to drive the heat dissipation medium to move with a larger power, thereby achieving the purpose of quickly dissipating heat for the first electronic device; when the temperature of the first electronic device drops a little, the first electronic device can control the second electronic device to drive the heat dissipation medium to move with a smaller power, thereby reducing the power consumption of the first electronic device while dissipating heat from the first electronic device; when it is determined that the temperature of the first electronic device drops below a preset value, the first electronic device can stop supplying power to the second electronic device, so that the second electronic device stops working.

[0189] In this way, this technical solution can control the operating power of the second electronic device in real time according to the temperature of the first electronic device, thereby adjusting the temperature of the first electronic device in real time.

[0190] In other examples, after step 540, the method 500 may further include:

[0191] 545 , the first electronic device determines whether it is the first time to wear the second electronic device.

[0192] For step 545 , please refer to the relevant description of step 445 above.

[0193] In some cases, when a first electronic device is supplying power to a second electronic device, if it determines that the first electronic device is in a specific state, such as a call or recording, the first electronic device may stop supplying power to the second electronic device, thereby not affecting the current state of the first electronic device. Alternatively, when the battery level of the first electronic device is low, the first electronic device may also stop supplying power to the second electronic device to save power. This technical solution will be described below with reference to FIG7 .

[0194] FIG7 is a schematic interactive diagram of another heat dissipation method provided by an embodiment of the present application. As shown in FIG7 , the method 600 may include steps 610 to 680 .

[0195] 610. The first electronic device determines whether the first electronic device is worn by the second electronic device.

[0196] 620. When it is determined that the first electronic device is worn by the second electronic device, the first electronic device supplies power to the second electronic device.

[0197] 630. The first electronic device obtains device information of the second electronic device.

[0198] 640. The first electronic device determines, based on the device information of the second electronic device, that the second electronic device is a heat dissipation device.

[0199] 650. When it is determined that the temperature of the first electronic device is greater than a preset value A, the first electronic device sends indication information A to the second electronic device.

[0200] 660 , the second electronic device drives the heat dissipation medium to move according to the instruction information A.

[0201] It should be understood that steps 610-660 can refer to the relevant description of steps 410-460 in the previous text, and for the sake of brevity, they are not repeated here.

[0202] 670. The first electronic device determines whether the first electronic device is in the first state.

[0203] Exemplarily, the first state may include but is not limited to: a voice call state, a video call state, a recording state, and a battery level lower than a preset battery level.

[0204] 680. When it is determined that the first electronic device is in the first state, the first electronic device stops supplying power to the second electronic device.

[0205] Since the second electronic device needs to drive the heat dissipation medium to move when the first electronic device supplies power to the second electronic device, some components in the second electronic device will vibrate slightly during operation; when the first electronic device is in the above-mentioned voice call state, video call state, and recording state, the vibration of some components in the second electronic device will affect the user's call quality or recording quality, so the first electronic device can stop supplying power to the second electronic device to reduce interference with the business of the first electronic device.

[0206] Similarly, when the battery level of the first electronic device falls below a preset level, continuing to supply power to the second electronic device will accelerate the power consumption of the first electronic device, causing it to be on the verge of shutting down. Therefore, the first electronic device can stop supplying power to the second electronic device to reduce the power consumption of the first electronic device.

[0207] The embodiment of the present application does not limit the specific value of the preset power value. For example, the preset power value is 20% or 25%.

[0208] The embodiment of the present application does not limit the specific execution order of the above steps 610-680. Some steps in these steps 610-680 may be omitted or replaced by other steps. In other embodiments, these steps 670-680 may be executed after step 650. In this case, even if the temperature of the first electronic device is high, if it is determined that the first electronic device is in the first state, the first electronic device may not supply power to the second electronic device. In this case, the method 600 may not execute step 660.

[0209] In an embodiment of the present application, during the process of a first electronic device supplying power to a second electronic device, or when the temperature of the first electronic device is greater than a preset value and is about to send indication information to the second electronic device, it can be determined whether the first electronic device is in a call, recording, low power, or other state; if it is determined that the first electronic device is in the above state, the first electronic device can stop supplying power to the second electronic device to ensure that the current business of the first electronic device can proceed smoothly or save power consumption of the first electronic device.

[0210] It is understandable that the various embodiments described above can be combined with each other or partially combined to form a new technical solution, and such a technical solution should not be considered to exceed the scope of protection of this application.

[0211] For example, in the method 500 above, in steps 550 and 570, the first electronic device can also determine whether the first electronic device is in the first state. If the first electronic device is not in the first state, the first electronic device can send an instruction message to the second electronic device to instruct the second electronic device to work; if the first electronic device is in the first state, the first electronic device can stop supplying power to the second electronic device.

[0212] FIG8 is a schematic flow chart of a heat dissipation method provided in an embodiment of the present application. As shown in FIG8 , the method 700 can be applied to an electronic device, and the method 700 can include steps 710 to 730 .

[0213] 710. When the first electronic device is worn by the second electronic device, obtain the temperature of the first electronic device.

[0214] For example, when a first electronic device is worn on a second electronic device, the first electronic device may obtain the temperature of the first electronic device through a temperature sensor or the like.

[0215] In some implementations, the first electronic device may also determine whether the second electronic device is being worn through a hall component. For details, please refer to the relevant description above.

[0216] It should be understood that the first electronic device can also determine whether the second electronic device is being worn through other methods. For example, the first electronic device can directly enable the reverse charging function. Then, if it can obtain information about the other device, it can determine that the second electronic device is being worn; otherwise, it can determine that the second electronic device is not being worn.

[0217] 720 , when the temperature of the first electronic device is greater than or equal to a preset value, supply power to the second electronic device and control the second electronic device to drive the heat dissipation medium to move at the first power.

[0218] When a first electronic device is worn with a second electronic device, the first electronic device can detect its temperature in real time. When the temperature of the first electronic device is greater than or equal to a first preset value, power is supplied to the second electronic device and the second electronic device is controlled to drive the heat dissipation medium to move at the first power.

[0219] The embodiment of the present application does not limit the specific value of the first preset value. For example, the first preset value can be 40 degrees or 50 degrees.

[0220] The way in which the first electronic device supplies power to the second electronic device may be wireless reverse charging or wired charging, which is not limited in the embodiment of the present application.

[0221] 730 , the second electronic device drives the heat dissipation medium to move at the first power.

[0222] The second electronic device can drive the heat dissipation medium to move with the first power according to the power supply of the first electronic device, thereby dissipating heat for the first electronic device through the movement of the heat dissipation medium.

[0223] The heat dissipation medium may be a liquid cooling medium, for example, the liquid cooling medium may include water, fluorinated liquid, mineral oil, etc. The specific content of the liquid cooling medium is not limited in the embodiment of the present application. The heat dissipation medium may also be a liquid-gas mixture, etc.

[0224] In an embodiment of the present application, when a first electronic device is worn on a second electronic device, the temperature of the first electronic device can be obtained. When the temperature of the first electronic device is greater than or equal to a first preset value, power is supplied to the second electronic device and the second electronic device is controlled to drive the heat dissipation medium to move. In this way, when the temperature of the first electronic device is high, the first electronic device can accurately control the second electronic device to drive the heat dissipation medium to move to dissipate heat from the first electronic device. Since the second electronic device is worn on the first electronic device, when the heat dissipation medium in the second electronic device moves, it can quickly remove heat from the back panel of the first electronic device, thereby achieving efficient heat dissipation of the first electronic device.

[0225] In other examples, the second electronic device may further include a fan, which may be driven by the second electronic device based on the power supply of the first electronic device to accelerate energy flow on the back panel of the first electronic device, thereby dissipating heat for the first electronic device. Alternatively, the second electronic device may further drive the fan to rotate and the heat dissipation medium to move based on the power supply of the first electronic device, thereby quickly dissipating heat for the first electronic device.

[0226] In some embodiments, the first electronic device controls the second electronic device to drive the heat dissipation medium to move at a first power, including:

[0227] The first electronic device sends first instruction information to the second electronic device, where the first instruction information is used to instruct the second electronic device to drive the heat dissipation medium to move according to the first power.

[0228] Exemplarily, the first electronic device and the second electronic device can negotiate the initial power for the second electronic device to start driving the heat dissipation medium to move. For example, the initial power may include multiple power levels corresponding to multiple working gears of the second electronic device, such as 5 watts (watt, W) corresponding to gear 1, 10W corresponding to gear 2, and 15 watts corresponding to gear 3. The first indication information can be used to indicate a specific wattage, or it can be used to indicate identification information of the corresponding wattage or gear.

[0229] Based on the embodiment of the present application, the first electronic device can send a first indication message to the second electronic device to instruct the second electronic device to drive the heat dissipation medium to move according to the first power, so that the first electronic device can accurately control the power of the second electronic device through the first indication message, thereby accurately controlling the heat dissipation of the first electronic device.

[0230] In other embodiments, the first electronic device may not send the first indication information to the second electronic device, but directly supply power to the second electronic device at the first power.

[0231] In some embodiments, the method 700 further includes:

[0232] After the first preset time period, the first electronic device controls the second electronic device to drive the heat dissipation medium to move at a second power, wherein the second power is less than the first power.

[0233] For example, the first power may be 10W, the second power may be 6W, and so on.

[0234] This application does not limit the specific value of the first preset time length. For example, the first preset time length can be 1 minute or 30 seconds.

[0235] In the embodiment of the present application, the second electronic device requires a relatively high power to initially drive the heat dissipation medium, but once the heat dissipation medium begins to flow, a relatively low power is required to maintain the flow. Therefore, after a first predetermined period of time, the first electronic device controls the second electronic device to operate at a second power, thereby saving power consumption of the first electronic device.

[0236] In some embodiments, the method 700 further includes:

[0237] When the temperature of the first electronic device is greater than or equal to the second preset value and less than the first preset value, the first electronic device sends second indication information to the second electronic device, where the second indication information is used to instruct the second electronic device to drive the heat dissipation medium to move according to a third power, wherein the third power is less than the first power.

[0238] The embodiments of the present application do not limit the specific values ​​of the first preset value and the second preset value. For example, the first preset value may be 50 degrees and the second preset value may be 40 degrees; or the first preset value may be 45 degrees and the second preset value may be 35 degrees.

[0239] The embodiment of the present application does not limit the specific values ​​of the first power and the third power. For example, the first power may be 15W, and the third power may be 10W.

[0240] In some embodiments, the second indication information may be used to indicate a specific wattage, or may be identification information used to indicate a corresponding wattage or gear position.

[0241] In an embodiment of the present application, after the second electronic device starts working to dissipate heat for the first electronic device, the temperature of the first electronic device will decrease accordingly. When the temperature of the first electronic device is greater than or equal to the second preset value and less than the first preset value, second indication information can be sent to the second electronic device to instruct the second electronic device to drive the heat dissipation medium to move at a third power that is less than the first power, thereby reducing the power consumption of the first electronic device while dissipating heat.

[0242] In another example, when a first electronic device is worn while a second electronic device is worn, and the temperature of the first electronic device is greater than or equal to a second preset value and less than a first preset value, the first electronic device can directly send the second indication information to the second electronic device. Thus, when the temperature of the first electronic device varies, the first electronic device can send different indication information to the second electronic device, instructing the second electronic device to drive the heat dissipation medium at different powers, thereby accurately dissipating heat for the first electronic device.

[0243] In some embodiments, the method 700 further includes:

[0244] When the temperature of the first electronic device is lower than a second preset value, the first electronic device stops supplying power to the second electronic device.

[0245] For example, when the first electronic device supplies power to the second electronic device via wireless reverse charging, when the temperature of the first electronic device is lower than a second preset value, the first electronic device may disable the wireless reverse charging function to stop supplying power to the second electronic device.

[0246] Based on the embodiment of the present application, as the second electronic device operates, the temperature of the first electronic device decreases. When the temperature of the first electronic device is less than a second preset value, the first electronic device can stop supplying power to the second electronic device to stop heat dissipation, thereby avoiding the situation where the second electronic device is still operating when the temperature of the first electronic device is already low.

[0247] In some embodiments, the method 700 further includes:

[0248] When the first electronic device is in the first state, the first electronic device stops supplying power to the second electronic device.

[0249] Exemplarily, the first state may include but is not limited to: a voice call state, a video call state, a recording state, and a low battery state.

[0250] According to the embodiment of the present application, since the second electronic device relies on the power supply of the first electronic device to operate, and the second electronic device generates a certain amount of vibration when operating, the first electronic device can stop supplying power to the second electronic device when the first electronic device is in the first state, thereby reducing the impact on the current business of the first electronic device or saving the power consumption of the first electronic device.

[0251] In some embodiments, before the first electronic device controls the second electronic device to drive the heat dissipation medium to move at the first power, the method 700 further includes:

[0252] The first electronic device obtains device information of the second electronic device;

[0253] The first electronic device determines, through the device information, that the second electronic device is a heat dissipation device.

[0254] In some embodiments, when a first electronic device is powered by a second electronic device via wireless reverse charging, the first electronic device can obtain device information of the second electronic device via a wireless charging protocol. This device information may include one or more of the following: the product serial number, product type, configuration information, MAC address, and the like of the second electronic device.

[0255] For example, the first electronic device may send a request message to the second electronic device. After receiving the request message, the second electronic device sends the device information of the second electronic device to the first electronic device, so that the first electronic device can obtain the device information of the second electronic device.

[0256] For another example, after the first electronic device wirelessly supplies power to the second electronic device, the second electronic device may actively send its device information to the first electronic device.

[0257] Based on the embodiment of the present application, the first electronic device can also obtain the device information of the second electronic device, and further determine that the second electronic device is a heat dissipation device based on the device information. This technical solution is beneficial for the first electronic device to determine the device type of the second electronic device.

[0258] In some embodiments, the method 700 further includes:

[0259] When the first electronic device is worn by the second electronic device for the first time, controlling the second electronic device to drive the heat dissipation medium to move for a second preset time period;

[0260] When it is not the first time that the first electronic device is worn with the second electronic device, the first electronic device stops supplying power to the second electronic device.

[0261] The embodiment of the present application does not limit the specific value of the second preset time length. For example, the second preset time length can be 1 minute or 2 minutes.

[0262] It should be understood that when the first electronic device is not worn for the first time, the first electronic device stops supplying power to the second electronic device on the premise that the temperature of the first electronic device is low and does not exceed the preset value.

[0263] Based on the embodiment of the present application, the first electronic device can also control the second electronic device to operate for a second preset time when the second electronic device is worn for the first time, so as to show the user the heat dissipation effect of the second electronic device on the first electronic device; when the first electronic device is not the first time the second electronic device is worn, the first electronic device stops supplying power to the second electronic device to save power consumption.

[0264] In some embodiments, before supplying power to the second electronic device, the method 700 further includes:

[0265] The first electronic device determines that the second electronic device is worn on the first electronic device through the Hall element.

[0266] Based on the embodiment of the present application, the first electronic device can conveniently determine whether the second electronic device is being worn through a Hall element.

[0267] In some embodiments, the method 700 further includes:

[0268] The first electronic device supplies power to the second electronic device or stops supplying power to the second electronic device according to a user operation.

[0269] In some embodiments, the display interface of the battery of the first electronic device may include a wireless reverse charging function button, and the user can use the wireless reverse charging function button to control the first electronic device to supply power to the second electronic device or stop supplying power to the second electronic device.

[0270] Based on the embodiment of the present application, the first electronic device can also supply power to the second electronic device or stop supplying power to the second electronic device according to the user's operation. In this way, the user can also independently decide whether to let the second electronic device dissipate heat for the first electronic device.

[0271] In some embodiments, a first electronic device supplies power to a second electronic device, including:

[0272] The first electronic device supplies power to the second electronic device in a wireless reverse charging manner.

[0273] Based on the embodiment of the present application, the first electronic device can have a wireless reverse charging function, so that it can conveniently power the second electronic device that is worn.

[0274] In other examples, the first electronic device may also supply power to the second electronic device in a wired manner, which is not limited in the embodiment of the present application.

[0275] In some embodiments, the second electronic device drives the heat dissipation medium to move at the first power, including:

[0276] The second electronic device receives the first indication information sent by the first electronic device;

[0277] The second electronic device drives the heat dissipation medium to move according to the first power according to the first instruction information.

[0278] Based on the embodiment of the present application, the second electronic device can receive the first instruction information sent by the first electronic device and drive the heat dissipation medium to move at the first power according to the first instruction information. In this way, the first electronic device can accurately control the power of the second electronic device.

[0279] In some embodiments, the method 700 further includes:

[0280] After the first preset time period, the second electronic device drives the heat dissipation medium to move according to a second power, wherein the second power is less than the first power.

[0281] Based on the embodiment of the present application, after the heat dissipation medium starts to flow, the required power is relatively small. At this time, the second electronic device can drive the heat dissipation medium to move according to the second power, thereby saving power consumption.

[0282] In some embodiments, the method 700 further includes:

[0283] The second electronic device receives the second indication information sent by the first electronic device;

[0284] The second electronic device drives the heat dissipation medium to move according to the second instruction information and at a third power, where the third power is less than the first power.

[0285] Based on the embodiment of the present application, the second electronic device can also receive the second instruction information sent by the first electronic device, and drive the heat dissipation medium to move according to the second instruction information at a third power that is less than the first power. This technical solution can save power consumption of the first electronic device.
