Problems solved by technology
The ensuing problem is that the large-screen mobile terminal consumes a lot of power and needs a short charging cycle
However, existing mobile terminals generate a lot of heat when charging. Usually, when charging, the mobile terminal is close to the desktop, forming a narrow and tight space, which accelerates the accumulation of heat and forces the terminal to reduce the charging current to alleviate the heating problem of the mobile phone. , seriously restricting the charging speed of mobile phones
[0003]
In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

The invention provides a cooling device of a mobile terminal. The cooling device comprises a ventilation element, an electric driver and a sliding plate, wherein the ventilation element is rotatably arranged at a rear shell of the mobile terminal and is provided with a first connection element, the electric driver is connected with a cooling element and a driving rod, the sliding plate is connected with a second connection element through a rotation element, the second connection element is connected to the driving rod to achieve linkage, a first elastic element is connected between the sliding plate and the ventilation element, and the sliding plate is further connected with a second elastic element; when the first connection element and the second connection element are in a connection state, the first elastic element is in a stretching state, the second elastic element is in a compression state, and the ventilation element and the rear shell of the mobile terminal are arranged in the same plane; and when the electric driver drives the driving rod to move, the first connection element and the second connection element are separated, the ventilation element rotates, and a ventilation hole is formed in the rear shell of the mobile terminal. The invention also provides the mobile terminal comprising the abovementioned cooling device. Therefore, by the cooling device, the cooling effect during charging of a mobile phone can be improved.
Description
technical field [0001] The invention relates to the technical field of communications, in particular to a mobile terminal and a heat dissipation device thereof. Background technique [0002] With the development of communication technology, the application of intelligent mobile terminals has been widely popularized, and in order to improve user experience, mobile terminals are also gradually developing towards larger screens. The ensuing problem is that the large-screen mobile terminal consumes a lot of power and needs a short charging cycle. However, existing mobile terminals will generate more heat when charging. Usually, when charging, the mobile terminal is close to the desktop, forming a narrow and tight space, which accelerates the accumulation of heat and forces the terminal to reduce the charging current to alleviate the heating problem of the mobile phone. , seriously restricting the charging speed of the mobile phone. [0003] In summary, there are obviously inco...
