Abstract
The utility model relates to an automobile door handle capable of realizing gesture signal acquisition, which comprises a plastic shell and a PCB (printed circuit board) fixedly connected in the plastic shell, the PCB is provided with at least one millimeter wave radar, a power connector and a communication connector, the communication connector is connected with an automobile LIN (local interconnect network) bus through a signal line, and the signal line is connected with the automobile LIN bus. The power connector is connected with an automobile power supply through a wire. According to the door handle, the PCB is installed in the plastic shell of the door handle, the millimeter wave radar is arranged on the PCB, the millimeter wave radar can be used for detecting gesture actions of a human body and sending action signals to the trip computer, and the trip computer can judge different instructions of unlocking, door opening, door closing, vehicle locking and the like of a vehicle owner according to the gesture actions; and the electronic lock on the vehicle door is controlled to execute instructions, so that operations such as remote-control unlocking, door opening, door closing and vehicle locking are realized. Due to the fact that the millimeter wave radar is wide in detection range, the technical problem that a traditional unlocking mode is large in limitation can be solved, and vehicle door unlocking convenience is improved.
