The card holder 101 includes a card slot for mounting an electronic card of an electronic device, and the temperature controlled switch 102 includes a temperature sensing element 123, a signal processor 122, and a temperature controlled switch circuit 121, wherein the signal processor 122 is connected to the temperature sensing element 123 and the temperature controlled switch circuit 121.
The temperature sensing element 123 is configured to obtain a temperature parameter of the surface of the temperature sensing element 123, and send the obtained temperature parameter to the signal processor 122, where the signal processor 122 is configured to control a working state of the temperature control switch circuit 121 according to the temperature parameter.
Specifically, the electronic device may be a mobile phone, a tablet computer, and the like, which is not limited in this embodiment. The temperature control switch 102 may be connected to the card holder 101 by bonding, riveting, screw fastening, or fastening. The temperature control switch 102 and the card holder 101 realize space multiplexing, so that the space in the body of the electronic device is more compact and reasonable, and the electronic device is convenient to be designed in a light, thin and small mode.
In this embodiment, when the electronic device is in a standby state or a power-off state, if the user does not touch the surface of the temperature controlled switch 102, the temperature of the surface of the casing of the electronic device will be in a relatively constant state, that is, the temperature of the surface of the temperature controlled switch 102 will be in a relatively constant state. When the user needs the electronic device to execute the control function, the user needs to touch the temperature controlled switch 102 with a finger, and since a certain temperature difference exists between the temperature of the finger of the user and the temperature of the electronic device in the standby state or the shutdown state, when the user touches the temperature controlled switch 102 with the finger, the temperature of the surface of the temperature controlled switch 102 will change through heat conduction, that is, a temperature difference is caused on the surface of the temperature controlled switch 102.
The temperature sensing element 123 may be a pressure type temperature sensor, a resistance type temperature sensor, a thermocouple type temperature sensor, etc., which is not limited in this embodiment.
The temperature sensing element 123 is connected to the signal processor 122, that is, the output end of the temperature sensing element 123 is connected to the signal processor 122, and can send the obtained temperature parameter to the signal processor 122. The signal processor 122 is connected to the temperature-controlled switch circuit 121, and the signal processor 122 can control the on/off of the temperature-controlled switch circuit 121. Further, when the temperature switch circuit 121 is closed, the temperature switch circuit 121 will generate an electrical signal, and the electrical signal is transmitted to the motherboard 200 of the electronic device, and the motherboard 200 of the electronic device will control the electronic device to turn on or off, increase or decrease the volume, lock or unlock the screen, and so on according to the electrical signal.
The temperature sensing element 123 is used for sensing a temperature parameter of the surface of the temperature controlled switch 102, so that the signal processor 122 controls the operating state of the temperature controlled switch circuit 121 according to the temperature parameter. The temperature parameter may include a temperature difference, a number of temperature changes, and a temperature change duration at a unit time point or a unit time period. It can be understood that the touch or lift action of the user finger can be obtained according to the temperature parameter.
Further, in order to enrich the control functions of the temperature controlled switch assembly 100, a plurality of keys may be preset, for example, corresponding to a plurality of control functions, and different control functions corresponding to different temperature change times may be preset, such as turning on or off, increasing or decreasing the volume, locking or unlocking the screen, and so on. In the subsequent process, the signal processor 122 can determine whether the temperature change times on the surface of the temperature controlled switch 102 matches with the preset key stroke, and then control the temperature controlled switch circuit 121 to output electric signals corresponding to different control functions, so that the electronic device executes different control functions.
For example, the temperature-controlled switch 102 may be a temperature-controlled power switch, the electronic device includes a power supply, a first end of the temperature-controlled switch circuit 121 may be connected to the signal processor 122, a second end of the temperature-controlled switch circuit 121 may be connected to a motherboard, and the motherboard is connected to the power supply. At this time, it is possible to preset: when the electronic equipment is in a power-on state, the power-off state is determined when the temperature change times within the time threshold value are 2 times. Furthermore, when the electronic device is in the power-on state, if the temperature sensing element 123 is triggered 2 times within the time threshold, the signal processor 122 controls the temperature controlled switch circuit 121 to output an electrical signal indicating "power-off" so that the main board 200 of the electronic device controls the electronic device to power off and power off.
The temperature-controlled switch 102 may be a temperature-controlled volume switch, the electronic device includes a speaker, a first end of the temperature-controlled switch circuit 121 may be connected to the signal processor 122, a second end of the temperature-controlled switch circuit 121 may be connected to a motherboard, and the motherboard is connected to the speaker. At this point, it may be preset: when the electronic device is in a standby state, if the number of times of temperature change is 3 within the time threshold, the volume is increased. Furthermore, when the electronic device is in a standby state, if the temperature sensing element 123 is triggered 3 times within the time threshold, the signal processor 122 controls the temperature controlled switch circuit 121 to output an electric signal indicating "increase volume", so that the main board 200 of the electronic device controls the speaker to increase volume.
Different from the prior art, temperature detect switch 102 is established through covering at card support 101 structure surface to this application, wherein, signal processor 122 connects temperature-sensing element 123 and temperature detect switch circuit 121, temperature-sensing element 123 is used for obtaining the temperature parameter on temperature-sensing element 123 surface, and send the temperature parameter who obtains for signal processor 122, signal processor 122 is used for controlling the operating condition of temperature detect switch circuit 121 according to the temperature parameter, in order to carry out the multiple control function that preset the key journey corresponds, can reduce the quantity of the mechanical button structure on the electronic equipment, when promoting the whole pleasing to the eye degree of electronic equipment, can also promote the structural stability of electronic equipment casing.
In an embodiment, the temperature sensing element 123 is configured to obtain a first temperature value at a first time and a second temperature value at a second time, and send the first temperature value and the second temperature value to the signal processor 122. The signal processor 122 is configured to obtain a temperature difference between the first temperature value and the second temperature value according to the first temperature value and the second temperature value, and when the temperature difference is greater than or equal to a preset temperature threshold, the signal processor 122 is configured to control the temperature control switch circuit 121 to be closed to generate an electrical signal.
Specifically, when the electronic device is in a standby state, if the user does not touch the surface of the temperature-controlled switch 102, the temperature of the electronic device will be close to the ambient temperature. Since the ambient temperature changes with time, for example, the ambient temperature changes with seasons in one year, and the ambient temperature changes with day and night in one day, the temperature of the electronic device also changes with the change of the ambient temperature. Therefore, the temperature of the electronic device may be different according to the time point. When the user touches the electronic device in the standby state, the human body temperature of the user is generally maintained within a certain temperature range, and the temperature of the electronic device will change through heat conduction, that is, when the user touches the surface of the temperature controlled switch 102, a temperature difference will be caused on the surface of the temperature controlled switch 102, and the temperature difference will belong to the temperature difference range between the human body temperature and the temperature of the electronic device at the current time point.
Therefore, in order to more accurately determine whether the user touches the surface of the temperature controlled switch 102, a preset temperature threshold may be set, and the signal processor 122 is configured to control the temperature controlled switch circuit 121 to close to generate an electrical signal when the temperature difference is greater than or equal to the preset temperature threshold. The electrical signal is transmitted to the motherboard 200 of the electronic device, and the motherboard 200 of the electronic device controls the electronic device to power on or off, increase or decrease the volume, lock or unlock the screen, etc. according to the electrical signal.
The temperature sensing element 123 detects the temperature of the surface of the temperature controlled switch 102 to obtain a first temperature value, detects the temperature of the surface of the temperature controlled switch 102 at an interval of a sampling time to obtain a second temperature value, and sends the first temperature value and the second temperature value to the signal processor 122.

When the electronic device is in a standby state, whether a second temperature value obtained at the second time is the same as a first temperature value obtained at the first time may be determined to determine whether the temperature of the electronic device changes, and if it is determined that the second temperature value obtained at the second time is different from the first temperature value obtained at the first time, it indicates that the temperature of the electronic device changes, at this time, the signal processor 122 may calculate the temperature difference, and when the temperature difference is greater than or equal to a preset temperature threshold, the signal processor 122 is configured to control the temperature control switch circuit 121 to be closed to generate an electrical signal. For example, when the electronic device is in the standby state, the first temperature value is an ambient temperature of 20 ℃, the second temperature value is a human body temperature value {36.5 ℃ -37.5 ℃ }, and then the temperature difference value is {16.4 ℃ -17.5 ℃ }.

Specifically, when the electronic device is in a standby state, if the user does not touch the surface of the temperature-controlled switch, the temperature of the electronic device will approach the ambient temperature. Since the ambient temperature changes with time, for example, the ambient temperature changes with seasons in one year, and the ambient temperature changes with day and night in one day, the temperature of the electronic device also changes with the change of the ambient temperature. Therefore, the temperature of the electronic device may be different according to the time point.
When the user touches the electronic device in the standby state, the body temperature of the user is generally maintained within a certain temperature range, and the temperature of the electronic device changes through heat conduction, that is, when the user touches the surface of the temperature-controlled switch, a temperature difference is caused on the surface of the temperature-controlled switch, and the temperature difference belongs to the temperature difference range between the body temperature and the temperature of the electronic device at the current time point.
Therefore, in order to more accurately judge whether the user contacts the surface of the temperature controlled switch, a preset temperature threshold value can be set, and when the temperature difference value is greater than or equal to the preset temperature threshold value, the signal processor is used for controlling the temperature controlled switch circuit to be closed so as to generate an electric signal.

The user can set the sampling time according to the actual situation, for example, 0.1 to 5 seconds, that is, the interval between the first time and the second time is 0.1 to 5 seconds, for example, 0.1 second, 0.5 second, 1 second, or 5 seconds.
When the electronic equipment is in a standby state, whether a second temperature value acquired at a second time is the same as a first temperature value acquired at a first time can be judged to determine whether the temperature of the electronic equipment changes, if it is determined that the second temperature value acquired at the second time is different from the first temperature value acquired at the first time, the temperature of the electronic equipment changes, at the moment, the signal processor can calculate the temperature difference, and when the temperature difference is greater than or equal to a preset temperature threshold value, the signal processor is used for controlling the temperature control switch circuit to be closed so as to generate an electric signal.
