The invention discloses an electronic expansion valve, refrigeration equipment and an automobile. The electronic expansion valve comprises a valve body, a valve rod and a valve element. The valve body is provided with a valve port and a limiting groove. The valve rod is arranged in the valve body and is rotatably connected with the valve body; the valve element is movably arranged in the valve body between an opening position and a closing position, the valve element is divided into a valve needle and a limiting plate fixedly connected with the valve needle in a split mode, one end of the valve rod extends into the valve needle and is in threaded connection with the valve needle, a limiting part is arranged on the peripheral wall of the limiting plate in a protruding mode, and the limiting part is in threaded connection with the valve needle. The limiting part protrudes out of the peripheral wall of the valve needle in the radial direction of the valve body, and the limiting part is matched with the limiting groove in a limiting mode so as to limit rotation of the valve needle. According to the electronic expansion valve, the cutting amount of materials can be reduced.
