The invention discloses an electronic expansion valve, refrigeration equipment and an automobile. The electronic expansion valve comprises a valve element seat, a valve body assembly and a sealing ring. The valve core seat is provided with a valve core cavity and a valve port communicated with the valve core cavity; the valve body assembly comprises a connecting base and a valve element assembly, the connecting base is connected with a valve element base, the valve element base is located at the end, facing the valve port, of the connecting base, and the connecting base is provided with a guide hole communicating with the valve element cavity. The valve element assembly is arranged on the connecting base and can reciprocate along the guide hole and the valve element cavity so as to be used for closing or opening the valve port. The valve element seat is provided with a blocking part which is annularly arranged on the periphery of the valve element assembly and isolates the valve element cavity from the guide hole; the sealing ring is connected among the valve element assembly, the blocking part and the connecting base in a sealed mode. According to the electronic expansion valve, parts inside the electronic expansion valve are reduced, and the production cost is reduced.
