Further, the mounting position of the foam box 102 can be realized by the mounting and matching structure of the hanging lug 1101 and the plurality of bosses 803 on the door liner 802, which are located at different positions.

In some embodiments, referring to fig. 8 and 9, the door liner 802 includes two liner ribs 804 arranged at intervals, the liner ribs 804 extend in a vertical direction, and the foam device 100 is installed between the two liner ribs 804; specifically, referring to fig. 8 and 11, the bosses 803 are symmetrically disposed on opposite sides of the two bladder ribs 804, and a plurality of sets of bosses are disposed at intervals along the vertical direction, and the hanging lugs 1101 are disposed on outer walls of two sides of the foam box 102 and are matched with the bosses 803. Therefore, when the foam device 100 is idle, the installation of the foam box 102 and the door bladder 802 is more stable, so that a stable and detachable storage container is formed; and further, the mounting position of the foam box 102 can be realized by the mounting and matching structure of the lugs 1101 and the plurality of bosses 803 positioned on different positions on the container rib 804.

In some embodiments, referring to fig. 2 and 9, the hanging lugs 1101 are further respectively disposed on the outer walls of two sides of the foam holder 101 and are matched with the bosses 803, so that the foam holder 101 can be detachably mounted on the bosses 803 of the door liner 802 through the hanging lugs 1101 on the outer walls of two sides, and the foam device 100 can be more flexibly mounted.

In some embodiments, referring to fig. 2 and 11, the outer walls of two sides of the foam box 102 are recessed inwards to form a concave portion 207, the rear end face of the concave portion 207 abuts against the front end face of the bladder rib 804, and when the hanging lug 1101 of the foam box 102 is assembled with the boss 803 of the bladder rib 804, the matching width of the rear end face of the concave portion 207 and the front end face of the bladder rib 804 in the left-right direction is w, wherein w is greater than 2 mm. It can be understood that, due to the factors of the forming process, the height of the boss 803 formed by vacuum forming along the left-right direction is limited, so the mating force point between the hanging lug 1101 of the foam box 102 and the boss 803 is not at the central position of the foam box 102, therefore, when the foam box 102 carries the object, under the action of the gravity of the carried object, a rotation torque is formed, so that the rear end face of the concave portion 207 and the front end face of the liner rib 804 are under the stress supporting action, and for the structural reliability, the mating width w along the left-right direction of the foam box 102 and the liner 804 needs to meet the requirement of the above range, so as to ensure the stability when the foam box 102 and the door liner 802 are installed.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
