Abstract: The present application relates to the field of storage equipment and provides a door opening device and storage equipment. The door opening device includes a plurality of electromagnetic push rod structures, where each of the plurality of electromagnetic push rod structures includes a push rod; and a controller electrically connected to the plurality of electromagnetic push rod structures and is configured to drive a plurality of push rods of the plurality of electromagnetic push rod structures to act synchronously. The door opening device according to the present application can reduce the thickness of the door opening device to a large extent under the condition of ensuring the pushing force through synchronous action of the plurality of electromagnetic push rod structures arranged in parallel, which is helpful to improve the application range of the door opening device.
