The invention discloses an electronic expansion valve, refrigeration equipment and an automobile. The electronic expansion valve comprises a valve body, a bearing piece, a valve rod, a rotor assembly, a valve element and a limiting piece. The valve body is provided with a valve port. The bearing part is fixedly connected into the valve body; the valve rod is fixedly connected with the bearing piece, and the valve rod is provided with a first end and a second end which are oppositely arranged; the rotor assembly is arranged in the valve body and fixedly connected with the valve rod. The valve core is movably arranged in the valve body between an opening position and a closing position, and a first end of the valve rod extends into the valve core and is in threaded connection with the valve core; 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; the limiting piece is arranged in the valve body, a limiting hole is formed in the limiting piece, and the peripheral wall of the second end of the valve rod is matched with the limiting hole in a limiting mode. The electronic expansion valve can prevent the valve rod from swinging.
