All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The electronic device and the control method provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, an embodiment of the present application provides an electronic device, including: the heating module comprises a deformation coil 100, a heating module 200, a controller 300, a switch module 400 and at least two functional modules;
at least part of the deformation coil 100 is formed by winding a memory metal strip, and the heating module 200 is arranged adjacent to the deformation coil 100 to heat the deformation coil 100;
the deformation coil 100 is connected with the at least two functional modules through the switch module 400, and the heating module 200 and the switch module 400 are respectively electrically connected with the controller 300;
the deformation coil 100 has at least two working temperatures corresponding to the at least two functional modules, and one working temperature corresponds to one functional module.
Since at least a portion of the deformation coil 100 is formed by winding a memory metal strip, when the temperature of the deformation coil 100 changes, the shape of the deformation coil 100 changes, and accordingly, as the shape of the deformation coil 100 changes, the inductance value of the deformation coil 100 also changes. The shape change of the deformation coil 100 may specifically be: referring to fig. 9, in a normal state, the turns of the deformation coil 100 are arranged relatively loosely and the whole deformation coil 100 is in an "outward expansion state", referring to fig. 10, when the deformation coil 100 is heated, the distance between the turns of the deformation coil 100 is reduced, and at the same time, the deformation coil 100 is shrunk inward, that is, the diameter of the turns of the deformation coil 100 is reduced. When the heating of the deformation coil 100 is stopped and the temperature of the deformation coil 100 is returned to the normal state, the shape of the deformation coil 100 may be returned to the normal state.
It can be seen that the deformation coil 100 has different shapes and different inductance values under different operating temperatures of the deformation coil 100. Due to the deformation of the coil 100 with different inductance values, it is possible to adapt to functional modules in different operating bands. Therefore, the working frequency bands of the at least two functional modules may be different, and meanwhile, the corresponding relationship between different working temperatures of the deformation coil 100 and different functional modules of the at least two functional modules may be preset, that is, one working temperature corresponds to one functional module. Like this, when needing to start arbitrary functional module in two at least functional modules, only need by controller 300 control heating module 200 with deformation coil 100 heating to the operating temperature who corresponds with the functional module that needs start, simultaneously, control switch module 400 switches on deformation coil 100 and the functional module that needs start, can realize corresponding functional module's start.
Specifically, the deformation coil 100 may be partially or entirely formed by winding the memory metal strip. The heating module 200 may be an electric heating element that is commonly used in the prior art and can generate heat when being energized, wherein the deformation coil 100 may directly contact with the heating module 200, or may have a certain gap with the heating module 200, for example, the heating module 200 may be plate-shaped, and at this time, one end surface of the deformation coil 100 may be fixed to one end surface of the heating module 200. Alternatively, the heating module 200 may be rod-shaped, and in this case, the heating module 200 may be inserted into the deformation coil 100.
The at least two functional modules may be various functional modules derived based on a near field communication technology, for example, the functional modules may be a wireless charging module 502, various NFC modules 501, and the like, where the NFC module 501 specifically may be: an access control NCF module, a remote control key NCF module, a Radio Frequency Identification (RFID) module, and the like. In one embodiment of the application, the operating frequency of the entrance guard NCF module is 13.65MHz, the operating frequency of the remote control key NCF module is 433MHz, and the operating frequency of the RFID module is 868 MHz.
The controller 300 may be various control chips in an electronic device, for example, a Central Processing Unit (CPU) in the electronic device.
The switch module 400 may be configured to turn on or off the electrical connection between the deformation coil 100 and any one of the functional modules, and specifically, the switch module 400 may turn on one of the at least two functional modules and the deformation coil 100 at a time, and turn off the electrical connection between the other functional modules and the deformation coil 100.

For example, when it is required to control the deformation coil 100 and the NFC module 501 to be turned on, the controller 300 may control the active end of the first switch 401 to contact with the first connection end of the first switch 401, and control the active end of the second switch 402 to contact with the first connection end of the second switch 402, so that the deformation coil 100 and the NFC module 501 form a closed loop. Correspondingly, when the deformation coil 100 and the wireless charging module 502 need to be controlled to be conducted, the controller 300 may control the active end of the first switch 401 to be in contact with the second connection end of the first switch 401, and control the active end of the second switch 402 to be in contact with the second connection end of the second switch 402.

Referring to fig. 3, in another embodiment of the present application, the at least two functional modules include a first wireless charging module 505 and a second wireless charging module 506, and the switch module 400 includes a first switch 401 and a second switch 402; the input end of the deformation coil 100 is electrically connected to the fixed end of the first switch 401, the output end of the first wireless charging module 505 is electrically connected to the first connection end of the first switch 401, and the output end of the second wireless charging module 506 is electrically connected to the second connection end of the first switch 401; the output end of the deformation coil 100 is electrically connected to the fixed end of the second switch 402, the person-conveying end of the first wireless charging module 505 is electrically connected to the first connection end of the second switch 402, and the input end of the second wireless charging module 506 is electrically connected to the second connection end of the second switch 402.

The specific control principle is similar to that of the above embodiment, and is not described herein again to avoid repetition.
Referring to fig. 8, in another embodiment of the present application, the at least two functional modules include a first functional module 507, a second functional module 508, a third functional module 509, and a fourth functional module 510, where working frequency bands of the first functional module 507, the second functional module 508, the third functional module 509, and the fourth functional module 510 are different, and a specific control principle thereof is similar to that of the above embodiment, and is not repeated here to avoid repetition.
In this embodiment, since at least a portion of the deformation coil 100 is formed by winding a memory metal strip, when the temperature of the deformation coil 100 changes, the shape of the deformation coil 100 changes, and when the shape of the deformation coil 100 changes, the inductance value of the deformation coil 100 changes. Like this, only need to change deformation coil 100's temperature value, can make same deformation coil 100 can adapt the functional module of different working frequency channels, only need set up a deformation coil 100 in electronic equipment promptly, can adapt the demand of the near field communication of the different functional modules in the electronic equipment, be favorable to saving electronic equipment's installation space.
Optionally, the electronic device further includes a temperature detection element 900, the temperature detection element 900 is electrically connected to the controller 300, and the temperature detection element 900 is disposed at a side portion of the deformation coil 100 to detect the temperature of the deformation coil 100.
The temperature detecting element 900 may be a temperature sensor, a temperature detecting chip, a temperature detecting circuit, or the like, which are commonly known in the art.
Specifically, since the deformation coil 100 has different shapes at different temperatures, and the deformation coils 100 of different shapes have different inductance values, the deformation coils 100 of different inductance values can be adapted to the functional modules of different operating frequency bands. Therefore, when the deformation coil 100 needs to be matched with a specific functional module, the deformation coil 100 generally needs to be heated to a specific temperature or a specific temperature range, so as to match the inductance value of the deformation coil 100 with the operating frequency band of the corresponding functional module.
Based on this, in this embodiment of the application, through setting up temperature detecting element 900, like this, in heating the deformation coil 100 through heating module 200, temperature detecting element 900 can real-time supervision the temperature of deformation coil 100 to with the real-time transmission of monitoring result to controller 300. When detecting that the temperature value of the deformation coil 100 reaches the set range, the controller 300 may control the heating module 200 to reduce the heating temperature of the deformation coil 100, so that the temperature of the deformation coil 100 is maintained within the set range. So that the inductance value of the deformation coil 100 is maintained within the temperature range, thereby ensuring stable operation of the corresponding functional module.
Referring to fig. 7-8, in an embodiment of the present application, the controller 300 may store a heating control logic and a switching control logic in advance, and the controller 300 is electrically connected to the deformation coil 100 through a driving circuit 600. The temperature detecting element 900 may send the detected temperature value of the deformation coil 100 to the controller 300 and the driving circuit 600, respectively, and after receiving the temperature value, the controller 300 may control the switch module 400 based on the switch control logic; accordingly, the driving circuit 600 may call a heating control logic from the controller 300 after receiving the temperature value, and control the heating module 200 based on the heating control logic.
In addition, the controller 300 may further receive a control instruction input by a user based on Application software (App) in the electronic device, and control the heating module 200 and the switch module 400 based on the heating control logic and the switch control logic when receiving the control instruction, so as to trigger different functional modules.
Optionally, the at least two functional modules include a wireless charging module 502, and the electronic device further includes a charging detection element for detecting the wireless charging device 1000, where the charging detection element is electrically connected to the controller 300;
under the condition that the charging detection element detects that the wireless charging device 1000 is located within the preset range of the electronic device, a first detection signal is sent to the controller 300, so that the controller 300 controls the heating module 200 to heat the temperature of the deformation coil 100 to a first working temperature, and controls the switch module 400 to conduct the deformation coil 100 and the wireless charging module 502, wherein the first working temperature corresponds to the wireless charging module 502.
The wireless charging device 1000 may refer to a wireless charging base, and the wireless charging device 1000 may include an interaction module interacting with the charging detection element, so that the charging detection element may interact with the interaction module of the charging detection element and the wireless charging device 1000 to determine a relative position between the wireless charging device 1000 and an electronic device.
The charging detection element may be intermittently turned on to detect the relative position between the wireless charging device 1000 and the electronic device, for example, the charging detection element may be turned on every preset time period. The first detection signal may be a trigger signal for triggering the wireless charging module 502, specifically, when the controller 300 receives the first detection signal, the controller may control the heating module 200 to heat the deformation coil 100 to the first working temperature, and control the switch module 400 to turn on the deformation coil 100 and the wireless charging module 502 based on the controller 300, where the first working temperature corresponds to the wireless charging module 502, that is, the first working temperature is: among the at least two operating temperatures, an operating temperature corresponding to the wireless charging module 502. That is, the operating frequency band of the wireless charging module 502 matches the inductance value of the deformation coil 100 at the first operating temperature.
In this embodiment, by detecting the relative position between the wireless charging device 1000 and the electronic device based on the charging detection element, when the wireless charging device 1000 is detected to be within the preset range of the electronic device, it can be considered that the electronic device is approaching the wireless charging device 1000, and at this time, a user may need to wirelessly charge the electronic device through the wireless charging device 1000. Therefore, in this case, the first detection signal may be sent to the controller 300 to trigger the wireless charging function of the electronic device in advance, so as to facilitate the user to wirelessly charge the electronic device.
Referring to fig. 4, in an embodiment of the present application, the charging detection element includes a Hall sensor 700(Hall sensor), and when the Hall sensor 700 detects that an external magnetic field strength variation of the electronic device exceeds a preset threshold, it is determined that the wireless charging device 1000 is located within a preset range of the electronic device.
Specifically, since the wireless charging device 1000 may form a magnetic field around it, the magnetic field around the electronic device will change when the electronic device approaches the wireless charging device 1000. Therefore, in the embodiment of the present application, the magnetic field variation of the electronic device may be detected by the hall sensor 700 to determine whether the electronic device is close to the wireless charging device 1000.
Referring to fig. 5 to 6, in another embodiment of the present application, the charging detection element includes a first Ultra Wide Band (UWB) antenna, the wireless charging device 1000 includes a second Ultra Wide Band (UWB) antenna 1001 and an induction coil 1002, and the first Ultra Wide Band (UWB) antenna 800 is configured to identify a position of the second Ultra Wide Band (UWB) antenna 1001 to determine whether the wireless charging device 1000 is located within a preset range of the electronic device.
In this embodiment, whether the electronic device is close to the wireless charging device 1000 is determined by detecting the relative position between the electronic device and the wireless charging device 1000 based on the UWB antenna.
Optionally, the heating module 200 comprises a heat spreader plate, and the deformation coil 100 is connected to the heat spreader plate.
In particular, since the inner wall of the soaking plate has a vacuum chamber of a fine structure, it is generally made of copper. Therefore, vapor chambers generally have better heat dissipation properties. Like this, can be through supplying power to the soaking plate, so that the soaking plate produces the heat to the realization heats deformation coil 100, when stopping to the soaking plate power supply, because the distinctive heat dispersion of soaking plate, can make deformation coil 100's temperature resume to the temperature value under the normality fast, be favorable to improving the speed that deformation coil 100 switched between different states.
Referring to fig. 11, an embodiment of the present application further provides a control method applied to the electronic device according to the foregoing embodiment, where the method includes:
step S1101, acquiring a first trigger signal, where the first trigger signal is used to trigger the first target module;
step S1102, in response to the first trigger signal, controlling the heating module 200 to heat the deformation coil 100 to the target temperature based on the controller 300, and controlling the switch module 400 to connect the deformation coil 100 and the first target module based on the controller 300.
The first trigger signal may be a signal generated by the electronic device actively detecting the external environment based on the detection element, or may be a user instruction received by an application program in the electronic device, or may be an instruction sent by another external device received by the electronic device, which is not limited to this.
Specifically, the first target module may be any one of the at least two functional modules, and an operating frequency band of the first target module is matched with an inductance value of the deformation coil 100 at the target temperature.
In this embodiment, when a first trigger signal for triggering a first target module is acquired, the controller 300 controls the heating module 200 to heat the deformation coil 100 to the target temperature, and the controller 300 controls the switch module 400 to connect the deformation coil 100 and the first target module, so as to trigger the first target module, so that the deformation coil 100 cooperates with the first target module to implement the near field communication function corresponding to the first target. Because the first target module is any one of the at least two functional modules, the near field communication requirements corresponding to the at least two functional modules can be met only by arranging one deformation coil 100, and the saving of the installation space in the electronic device is facilitated.

In this embodiment, by providing the temperature detection element 900, in the process of heating the deformation coil 100 by the heating module 200, the temperature detection element 900 can monitor the temperature of the deformation coil 100 in real time and transmit the monitoring result to the controller 300 in real time. When detecting that the temperature value of the deformation coil 100 reaches the set range, the controller 300 may control the heating module 200 to reduce the heating temperature of the deformation coil 100, so that the temperature of the deformation coil 100 is maintained within the set range. So that the inductance value of the deformation coil 100 is maintained within the temperature range, thereby ensuring stable operation of the corresponding functional module.
Optionally, in a case that the first target module is the wireless charging module 502 and the electronic device includes a charging detection element, the acquiring the first trigger signal includes:

in the case that the charging detection element detects that the wireless charging device 1000 is located within the preset range of the electronic device, the charging detection element sends the first trigger signal to the controller 300.
In this embodiment, by detecting the relative position between the wireless charging device 1000 and the electronic device based on the charging detection element, when the wireless charging device 1000 is detected to be within the preset range of the electronic device, it can be considered that the electronic device is approaching the wireless charging device 1000, and at this time, a user may need to wirelessly charge the electronic device through the wireless charging device 1000. Therefore, in this case, the first detection signal may be sent to the controller 300 to trigger the wireless charging function of the electronic device in advance, so as to facilitate the user to wirelessly charge the electronic device.
Optionally, after the controller 300 controls the switch module 400 to turn on the deformation coil 100 and the first target module, the method further includes:
detecting whether the wireless charging device 1000 is located outside a preset range of the electronic device based on the charging detection element;
in the case that the charging detection element detects that the wireless charging device 1000 is located outside the preset range of the electronic device, the charging detection element sends a second trigger signal to the controller 300;
in response to the second trigger signal, the controller 300 controls the heating module 200 to stop heating the deformation coil 100, and the controller 300 controls the switch module 400 to connect the deformation coil 100 and a second target module of the at least two functional modules.
The first target module and the second target module are different functional modules of the at least two functional modules, and the working frequency band of the second target module is matched with the inductance value of the deformation coil 100 under the condition of no heating.
In this embodiment, after the wireless charging function of the electronic device is started, the relative position between the electronic device and the wireless charging device 1000 may be further detected based on the charging detection element, and when the wireless charging device 1000 is located outside the preset range of the electronic device, it may be considered that the electronic device has been separated from the wireless charging device 1000, and at this time, the charging detection element may send a second trigger signal to the controller 300, where the second trigger signal is used for triggering the second target module. After receiving the second trigger signal, the controller 300 may control the heating module 200 to stop heating the deformation coil 100, so that the temperature of the deformation coil 100 is reduced to the unheated temperature, and meanwhile, the controller 300 may also control the switch module 400 to connect the deformation coil 100 and the second target module, so as to start the near field communication function corresponding to the second target module.
