Background

At present, most of clothes display adopts plastic mannequins, but the mannequins are standard models, and the characteristics of people are different, so that people can know whether the mannequins are suitable or not by finding corresponding products to try on when having buying intentions.

With the popularization of 5G technology, various forms of live online shopping in the new retail field of clothing can become mainstream in the future, and the customer-substitute fitting technology of the clothing under the 'person-goods' separation scene is indispensable. The solution of the industry at present is that the entity robot is deformed to try on for a guest, but the deformation range is small, one robot is expanded into one or two sizes at most from a small size during the simulation of important parameters such as three-dimensional space, and from XS size to XXXL size, the simulation of multiple sizes can be realized only by the connection and the matching of a plurality of sets of robots, so that the operation cost of retail merchants is increased.

The reason for this is the limitation of the push-out structure adopted by the existing fitting robot. The existing extrapolation technology adopts a traditional linear displacement structure no matter a guide rail push rod or a threaded screw rod, and is characterized in that the guide rail or the screw rod and the displacement direction are on the same horizontal line, so that the size of a transversely fixed guide rail must be very small under the condition that the original size of a model is very small, namely the retraction state of all moving positioning parts requires very small size, and the original size of the transverse guide rail serving as a support and orientation is also very small, thereby limiting the push stroke of a moving rod along the guide rail.

For example, in the waist of a small S-size female model, the original size waist width of hardware does not exceed 18 cm, the thickness of a skin material and the space occupied by an internal connecting piece are removed, the left and right unidirectional guide rails or screw rods are 6 cm at most, the sliders on the guide rails or the screw rods occupy 3 cm, and the horizontal expansion is 3 cm at most, so that only one size body type can be expanded.

Disclosure of Invention

The present invention is directed to a high expansion ratio structure and an expansion device for a deformable model to solve the above problems.

In order to achieve the purpose, the high expansion ratio structure for the deformable model comprises two supports which are arranged in parallel, wherein a cross connecting rod group is arranged between the two supports and comprises a plurality of connecting rods which are hinged in a cross mode, the connecting rods which are hinged in the cross mode form a parallelogram structure, and the end parts of the connecting rods on the lower sides of the two ends of the cross connecting rod group are hinged to the bottoms of the supports; the upper part of the bracket is provided with a through groove slide rail, a sliding table connecting piece is arranged in the through groove slide rail, and the end parts of the upper side connecting rods at the two ends of the cross connecting rod group are hinged to the sliding table connecting piece.
