1. A concealed door handle, comprising:
a handle body;
a handle base fixed in a body of a vehicle, the handle body being concealed in the handle base, and the handle body being rotatably connected to the handle base;
a deployment mechanism comprising a microswitch and microswitch trigger block, the microswitch arranged on the handle base and configured to detect a deployed position of the handle body and to maintain communication with a vehicle control module, wherein when the deployment microswitch is moved by the handle body from a triggered state into an untriggered state, the deployment microswitch sends an input signal for unlocking an electronic lock to the vehicle control module; and
a retraction microswitch configured to detect a retracted position of the handle body and to maintain communication with the vehicle control module, the retraction microswitch being arranged on the handle base, wherein:
the handle body has the retracted position, the deployed position and a release position in sequence as the position of a rear end of the handle body changes from inside to outside,
when the handle body is in the retracted position, the deployment microswitch is not triggered, and the retraction microswitch is triggered,
when the handle body is in the deployed position, the deployment microswitch is triggered, and the retraction microswitch is not triggered, and
when the handle body is in the release position, neither the deployment microswitch nor the retraction microswitch is triggered, then an input signal is sent for unlocking an electronic lock to the vehicle control module.
