  • Modular structure of an interior assembly
    Patent number: 11147350
    Abstract: A modular structure of an interior assembly relates to the field suitcases. A first snap-fit groove is provided around an outer side of a middle frame, and an opening of the first snap-fit groove is provided downward. A second snap-fit groove is provided around an inner side of the middle frame, a first protrusion and a sliding member are provided in the second snap-fit groove, and an opening of the second snap-fit groove is provided upward. An upper end of a shell is snap-fitted into the first snap-fit groove to be combined with the middle frame, and the card is combined with the inner assembled structure. Subsequently, the card is inserted into the second snap-fit groove, the second protrusion fixes the card in the second snap-fit groove through the sliding member and the first protrusion, and the step-like member and the sliding member are fixed by a snap-fit connection.

  • Device for automatically assembling shell and middle frame by glue and use method thereof
    Patent number: 10697487
    Abstract: A device for automatically assembling a shell and a middle frame by glue includes a locating mechanism of the middle frame, a glue coating mechanism, a feed mechanism, a press-in mechanism, and a pressure-keeping mechanism. Components to be assembled are transferred among the locating mechanism of the middle frame, the glue coating mechanism, the feed mechanism, the press-in mechanism, and the pressure-keeping mechanism through manipulators. An automatic assembly line is formed by the device to assemble various components of the case body, which considerably reduces the manual assembly cost, simplifies the complicated assembly process, effectively shortens the whole production period, and improves the production efficiency.
