The first end of the drive assembly 3 is fixedly connected to the inner side of the handle body 1. The handle body 1 is movably mounted on the vehicle body. The electromagnetic locking assembly 2 drives the handle body 1 to a concealed position. When the electromagnetic locking assembly 2 is energized, it provides a locking force to retract the handle body 1 to the same position as the outer wall of the door. When the electromagnetic locking assembly 2 is de-energized, the electromagnetic locking assembly... 2. No longer providing locking force, under the elastic force of the drive component 3, the drive component 3 drives the handle body 1 to move to the first door opening position, that is, the handle body 1 protrudes from the car door and is separated from the outer wall of the car door. When the electromagnetic locking component 2 is energized, the door handle body 1 is in a hidden state. When the vehicle is involved in an emergency such as a collision or water ingress, the electromagnetic locking component 2 is de-energized, and the door handle body 1 actively unfolds to the first door opening position. Rescue personnel only need to pull the door handle body 1 to open the car door, which shortens the rescue time, reduces the difficulty of rescue, and also avoids the economic losses caused by violent damage to the car door.

Next, the other end of the electromagnetic coil 202 is a free end, wherein the free end of the magnetic core 201 is movably disposed inside the free end of the electromagnetic coil 202, and the free end of the magnetic core 201 extends into the free end of the electromagnetic coil 202. The electromagnetic coil 202 is connected to a power source. When the electromagnetic coil 202 is energized, the electromagnetic coil 202 generates a magnetic force. The direction of the magnetic field generated by the energized electromagnetic coil 202 is consistent with the original magnetic field direction of the magnetic core 201 (or the magnetic field direction after the magnetic core 201 is magnetized). An attractive force appears between the electromagnetic coil 202 and the magnetic core 201. When the electromagnetic coil 202 is de-energized, the attractive force between the electromagnetic coil 202 and the magnetic core 201 disappears.

[0033] Specifically, in one optional embodiment of this application, multiple electromagnetic locking components 2 and multiple driving components 3 are provided, and the multiple electromagnetic locking components 2 and multiple driving components 3 are respectively provided at both ends of the handle body 1 in the length direction; in this embodiment, two electromagnetic locking components 2 and two driving components 3 are provided, and the two electromagnetic locking components 2 and two driving components 3 are respectively provided at both ends of the handle body 1 in the length direction (front and rear direction of the vehicle body). Both ends of the handle body 1 in the length direction are provided with protective shells 5 extending along the direction close to the mounting base 4. One end of the protective shell 5 is close to the mounting base 4 of the handle body 1.
