[0029] The signal generating mechanism 3 includes a signal generator 301, and a signal transmitting chip is arranged inside the signal generator 301 for transmitting an identification signal to the driverless car so that the driverless car can perform trajectory correction adjustment according to the signal. A flange base 302 is fixedly connected to the left side of the signal generator 301, and the flange base 302 is connected to the connecting flange plate 201. A wiring groove 304 is arranged on the left axis of the signal generator 301, and a wire is plugged into the wiring groove 304, and the wire extends to the battery compartment 104 for electrical connection.
