Abstract: Systems, methods, and apparatuses for controlling objects being loaded or unloaded from a storage structure or vehicle, such as a trailer. In example embodiments, a plurality of parcels may be stored in or on a trailer that is attached to a cab of a delivery vehicle. Upon arrival at a deposit location, the trailer loaded with the one or more parcels may be removably secured to a an adjustable platform designed to be raised to a predetermined angle for unloading of the one or more parcels. Once the adjustable platform is raised to the predetermined angle, a plurality of adjustable dividing mechanisms may be configured to pivot, allowing for the movement of a controlled volume of the one or more parcels onto the receiving platform.

Abstract: A height-adjustable desk includes a desk board and a base. Two first lifting arms and one second lifting arm are disposed between the desk board and the base. The two first lifting arms are disposed at both sides of the desk board respectively. The second lifting arm is located between the two first lifting arms and spatially intersected with the two first lifting arms to be distributed in an X shape. The upper ends of the two first lifting arms are rotatably connected to a first end of the desk board, and the lower ends of the two first lifting arms are slidably connected to a first end of the base. The upper end of the second lifting arm is slidably connected to a second end of the desk board, and and the lower end of the second lifting arm is hinged to a second end of the base.

Abstract: A vehicle bottom structure includes a slope device including a slope plate and guide rails, floor crossmembers, and a floor panel structure. The floor crossmembers are arranged at intervals in the vehicle front-rear direction. The slope device is provided between paired floor crossmembers, and the slope device is provided below a standing-ride region. The floor panel structure is provided over the paired floor crossmembers such that the floor panel structure is placed above the slope device and serves as a floor material in the standing-ride region. The floor panel structure includes panel segments extended in the vehicle front-rear direction so as to be provided over the paired floor crossmembers, and the panel segments are shorter than the whole length of the standing-ride region in the vehicle width direction. The panel segments are arranged side by side in the vehicle width direction in the standing-ride region.
