[0002] like Figure 1 As shown, it is a view of an existing hidden car door handle, including a door sheet metal 6 and a hidden handle 2. The door sheet metal 6 is provided with an avoidance groove 6a corresponding to the hidden handle 2. In order to reduce wind resistance during driving and increase the aesthetic appearance of the car, the hidden handle 2 is hidden and retracted into the avoidance groove 6a when the car is driving or parked. However, with the popularization of hidden door handles, a serious problem generally arises in the cold winter, that is, the weather in the north is relatively cold, especially in winter, there may even be blizzards with temperatures of dozens of degrees below zero, which will cause the gap between the hidden handle and the avoidance groove to be frozen. At this time, the hidden handle is unlocked using the smart key. The hidden handle will not pop out automatically due to being frozen, so the car door cannot be unlocked. At the same time, since the surface temperature of the hidden handle is low at low temperatures, the driver's hands will be frozen when unlocking the car through the hidden handle, and in severe cases, there is even the possibility of frostbite, which needs to be improved urgently.
