    Abstract: An advanced chassis structure design offers more battery storage spaces than same-class electric vehicles. The chassis structure provides four battery storage spaces. The significance of these additional storage areas lies in their direct impact on extending the driving range of the vehicle. The chassis structure design further addresses the issue of battery replacement in an electric vehicle chassis. Typically, when an electric vehicle runs out of battery, it takes several minutes or even hours for the battery to be fully recharged. When the battery is broken, the replacement process often involves significant disassembly, which is also time-consuming. With the chassis structure design, the battery is positioned underneath the chassis and fastened within the battery tray and protective battery case. This means that when it comes to battery replacement, the battery can be swapped just by removing a few screws.

    Abstract: A two-level expandable house structure can be used on an innovative recreational vehicle or new kind of movable house. The two-level structure will offer more space to people. For the same footprint area, a two-floor house will have more square footage of living space. The second level can be formed over a main section, which defines the footprint of the expandable house in the collapsed state, and also over one of the first story expansion sections that extend from one or both sides of the main section. Thus, the expandable house may expand to provide about four times the living space as compared to the main structure. A balcony may be provided over the second first story expansion sections, accessible from the second story.

    Abstract: An electric vehicle chassis includes multiple battery compartments specifically arranged therein. The chassis can include a main structure extending longitudinally along a length of the electric vehicle which it supports. The main structure can include a first, upper main structure battery compartment. A lower main structure frame can be disposed below the first, upper main structure battery compartment to provide a second, lower main structure battery compartment. Side battery compartments can be attached to opposite sides of the main structure frame to provide third and fourth, side battery compartments. Thus, the vehicle chassis can provide four distinctly positioned battery compartments for the placement of batteries for the electric vehicle, providing more battery storage spaces than conventional same-class electric vehicles.

    Abstract: A table with four chairs can be stored together into a secure, flattened assembly. The four chairs can store under the table such that, when the legs of the table are folded to be adjacent a back side of the table, the folded legs act as a stopper to prevent the chairs from sliding out when moving the table. A leg turning mechanism allows the user to turn two adjacent legs 180 degrees to permit the legs to be disposed adjacent each other when folded and, when unfolded, to present a uniform appearance for each of the legs. The foldable chairs can include a foldable backrest and can have support beams between each pair of legs. The chairs can be folded in a flattened state to be disposed in a slot adjacent the underside of the top of the table.

    Abstract: An integrated ceiling mainly includes an air supply system, an air return system, a frame system and a multifunctional system. The air supply system and air return system include a plurality of air duct modules assembled together. The frame system supports all air system modules on the ceiling, so the frame system should be installed first. The multi-function system is a ceiling module system that can be installed with functions other than ventilation, and has a plurality of ceiling multi-function modules. In addition to the above hardware systems, an HVAC routing aid design system can automatically design one or more indoor air system plans based on the actual installation conditions, space, and requirements.
