As shown in fig. 1, fig. 2 and fig. 3, an electronic device 1 according to an embodiment of the present invention includes a controller 2, a Proximity sensor (Proximity sensor)3, and at least one temperature sensor 4. The electronic device 1 may be a handheld device, such as a smart phone, a smart tablet, or a notebook, etc. for a user to perform operations, wherein fig. 2 and 3 are only examples of the smart phone, fig. 2 is a front view of the smart phone, and fig. 3 is a rear view of the smart phone. The controller 2 can be an embedded controller, a microprocessor, a processing unit, or an arithmetic logic unit, etc. for processing data and instructions of the electronic device 1. The proximity sensor 3 is connected to the controller 2, wherein the proximity sensor 3 is used to determine whether a human body approaches the electronic device 1. The at least one temperature sensor 4 is connected to the controller 2, wherein the at least one temperature sensor 4 is distributed on a housing surface 11 of the electronic device 1 for detecting a temperature of the housing surface 11 of the electronic device 1, and the position, shape, size and number of the temperature sensors 4 in fig. 2 and 3 are only examples, and a person skilled in the art can place the temperature sensors at different positions on the electronic device 1 according to actual requirements and design the shape, size and number of the temperature sensors, so the present invention is not limited thereto.
Fig. 4 is a flowchart of a temperature protection method for an electronic device according to an embodiment of the invention. In the present embodiment, the controller 2 in the electronic device 1 executes a temperature protection method, which includes: step S21: it is determined whether the temperature of a housing surface 11 of the electronic device 1 in a first operating state exceeds a temperature protection value, wherein the controller 2 senses whether the temperature of the housing surface 11 of the electronic device 1 in the first operating state exceeds the temperature protection value through at least one temperature sensor 4. The first operating state may be a fast charging state or a high performance state executed by the electronic device 1, wherein the fast charging state is a state in which the electronic device 1 receives an external power source and charges the electronic device with a large charging current, for example, 2 amperes (a), and the high performance state is a state in which the electronic device 1 operates in an over-frequency operation stage with a large operating current. The temperature protection value is preferably 48 degrees celsius, but the invention is not limited thereto, and those skilled in the art can adjust the value of the temperature protection value according to actual requirements. In detail, when the controller 2 determines that the temperature of the casing surface 11 of the electronic device 1 in the first operating state does not exceed the temperature protection value, the controller 2 continuously senses the temperature of the casing surface 11 of the electronic device 1 in the first operating state through the at least one temperature sensor 4. When the controller 2 determines that the temperature of the case surface 11 of the electronic device 1 in the first operation state exceeds the temperature protection value, it proceeds to step S23.
Step S23: it is determined whether a human body contacts the electronic device in the first operating state, wherein the controller 2 senses whether the human body contacts the case surface 11 of the electronic device 1 in the first operating state through the proximity sensor 3. In detail, when the controller 2 determines that the human body does not contact the case surface 11 of the electronic device 1 in the first operation state, the controller 2 continuously senses whether the human body contacts the case surface 11 of the electronic device 1 in the first operation state through the proximity sensor 3. When the controller 2 determines that the human body contacts the case surface 11 of the electronic device 1 in the first operation state, it proceeds to step S25.
Step S25: reducing an operating current of the electronic device 1 in the first operating state to bring the electronic device 1 from the first operating state into a second operating state, and bringing the temperature of the housing surface 11 of the electronic device 1 below the temperature protection value, wherein the controller 2 reduces an operating current of the electronic device 1 in the first operating state to bring the electronic device 1 from the first operating state into the second operating state. The second operating state may be a normal charging state or a normal performance state executed by the electronic device 1, wherein the normal charging state is a state in which the electronic device 1 receives an external power source and charges the electronic device with a normal charging current, for example, 0.5 amperes, and the normal performance state is a state in which the electronic device 1 operates in a down-conversion operating phase or a normal operating phase with a normal operating current. That is, when the controller 2 determines that the human body contacts the housing surface 11 of the electronic device 1 in the first operating state, the controller 2 reduces the charging current received by the electronic device 1 or reduces the operating current of the electronic device 1 to enable the electronic device 1 to enter the second operating state from the first operating state, thereby reducing the temperature of the electronic components inside the electronic device 1, achieving the purpose of reducing the surface temperature of the housing surface 11 of the electronic device 1, and reducing the probability of low-temperature scald of the user.
Step S27: it is determined whether the human body contacts the electronic device 1 in the second operation state, wherein the controller 2 senses whether the human body contacts the case surface 11 of the electronic device 1 in the second operation state through the proximity sensor 3. In detail, when the controller 2 determines that the human body contacts the case surface 11 of the electronic device 1 in the second operation state, the controller 2 continuously senses whether the human body contacts the case surface 11 of the electronic device 1 in the second operation state through the proximity sensor 3 and maintains the electronic device 1 in the second operation state. When the controller 2 determines that the human body does not contact the case surface 11 of the electronic device 1 in the second operation state, it proceeds to step S29.
Step S29: the operating current of the electronic device in the second operating state is increased to bring the electronic device from the second operating state into the first operating state, wherein the controller 2 increases the operating current of the electronic device 1 in the second operating state to bring the electronic device 1 from the second operating state into the first operating state. That is, when the controller 2 determines that the human body does not contact the housing surface 11 of the electronic device 1 in the second operating state, the controller 2 increases the charging current received by the electronic device 1 or increases the operating current of the electronic device 1 to enable the electronic device 1 to enter the first operating state from the second operating state, thereby increasing the charging current received by the electronic device 1 or increasing the operating current of the electronic device 1 to enable the electronic device 1 to enter the fast charging state or the high performance state again, so as to shorten the charging time of the electronic device 1 or enable the electronic device 1 to enter the optimal operating state.
In summary, the electronic device and the temperature protection method for the electronic device provided by the embodiments of the invention can determine whether the user touches the electronic device when the electronic device is in the fast charging state or the high-performance state, and can reduce the temperature of the surface of the housing of the electronic device when the user touches the electronic product, so as to reduce the probability of low-temperature scald. And when the electronic device is in a general charging state or a general performance state, whether a user touches the electronic device can be judged, and when the user does not touch the electronic product, the electronic device can be switched from the general charging state or the general performance state to a quick charging state or a high performance state, so that the charging time of the electronic device is shortened or the electronic device enters an optimal working state.
