Description

Drive assembly and refrigeration equipment Technical Field The invention relates to the technical field of household appliances, in particular to a driving assembly and refrigeration equipment. Background At present, a door seal strip with a magnetic strip is commonly used for sealing between a door body and a box body of a refrigerator, the door seal strip is installed on the door body and integrally formed with the door body, and the door body is attracted on the box body by means of magnetic force of the door seal strip, so that sealing between the door body and the box body is realized, and the heat preservation effect of the refrigerator is achieved. Because the contact surface of the door seal and the box body is longer, and the refrigerator is internally provided with a closed space due to sealing between the box body and the door body, when the door body needs to be opened, the door can be opened only by the magnetic force and the negative pressure of the internal space, the door opening difficulty of the old and the children is higher, and particularly when the user has articles in both hands, the user needs to put down the articles in the hands and then open the door, so that the inconvenience of the user is increased, and the time and the labor are wasted. In the related art, the door body is automatically opened through electromagnetic driving and motor driving, wherein when the door body is automatically opened through electromagnetic driving, the thickness of an electromagnetic driving structure is larger, so that the universality is not high. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art or related art. To this end, a first aspect of the invention provides a drive assembly. The second aspect of the present invention also provides a refrigeration apparatus. In view of the above, a first aspect of the present invention provides a driving assembly, which includes a push rod, a plurality of magnetic assemblies, wherein the plurality of magnetic assemblies are arranged at intervals along a length direction of the push rod, a first through hole is formed in any one of the magnetic assemblies, the plurality of first through holes of the plurality of magnetic assemblies are correspondingly arranged, the push rod is arranged in the first through holes of the plurality of magnetic assemblies in a penetrating manner, and the plurality of magnetic assemblies can drive the push rod to move along the length direction of the push rod.
