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 cavity, a valve port and a limiting groove, the valve rod is arranged in the valve cavity, and the valve rod is rotatably connected with the valve body; the valve element is movably arranged in the valve cavity between an opening position and a closing position, one end of the valve rod extends into the valve element and is in threaded connection with the valve element, the valve element is provided with a limiting part, and the limiting part is matched with the limiting groove in a limiting mode so as to limit rotation of the valve element; when the valve element is located at the closing position, the valve port is closed, and when the valve element is located at the opening position, the valve port is opened. According to the electronic expansion valve, abrasion between the valve element and the valve port can be avoided.
