A hollow chamber structural component includes a shell component which extends along a main extension direction. A cover component is attached to the shell component, wherein a hollow chamber is disposed between the shell component and the cover component and extends in the main extension direction. A reinforcing structure is arranged in the hollow chamber and comprises: a synthetic support structure, which follows at least in some sections the main extension direction and rests with at least some sections against an inside of the shell component; and at least one reinforcing element that follows at least in some sections the main extension direction and is joined to the synthetic support structure with the aid of a layer of adhesive.

The invention relates to a hydraulic support base. The hydraulic support base comprises a main reinforcement and two groove bodies defined by base plates. The main reinforcement comprises internal main reinforcement bodies and external main reinforcement bodies, an attached plate is arranged on the position, corresponding to a connecting hole of a connecting rod, of the internal side of the main reinforcement, and a reinforcing plate is arranged on the position, corresponding to a pillar nest, of the external side of the main reinforcement. The internal main reinforcement bodies and the external main reinforcement bodies are connected through a first horizontally-arranged cover plate, the adjacent internal main reinforcement bodies are connected through second obliquely-arranged cover plates, and a third obliquely-arranged cover plate connected with a gap bridge is arranged on the pillar nest and connected with the internal main reinforcement bodies and the external main reinforcement bodies. A second reinforcement plate is arranged outside the internal main reinforcement bodies in the length direction of the internal main reinforcement bodies, and a lifting lug is arranged on the second reinforcement plate. According to the hydraulic support base, by arranging the attached plate and the reinforcing plate on the main reinforcement, the strength and the anti-bending and anti-torque capacities of the hydraulic support base are improved, the stressed area of the base is increased, the overall length of the base and the length of a sidewalk are increased, the overall height of the hydraulic support base is decreased, and the hydraulic support base is suitable for exploitation of a thin coal seam.

The invention relates to the technical field of automobiles, in particular to an automobile body aluminum profile water tank column and an automobile. The automobile body aluminum profile water tank column comprises a main board, a first connecting frame and a second connecting frame. The first connecting frame and the second connecting frame are fixedly arranged on the same side of the main board; The first connecting frame comprises a first support plate and a second support plate; The first support plate and the second support plate together form a triangular cavity structure with the mainplate; The second connecting frame comprises a third support plate and a fourth support plate; The third support plate and the fourth support plate together with the main plate form a triangular cavity structure. The automobile body aluminum profile water tank column and the automobile provided by the invention are provided with two connecting frames arranged on the main board, so that one part isreliably connected with the other part at the same time by two identical side faces, and the cross-section structure enables the product to have higher strength, rigidity, bending and torsion resistance; Using aluminum alloy profile longitudinal / transverse beam, it has high strength and strength, and the investment of mould is low, and the production efficiency is high.

The invention provides a deformable biplane configuration. The configuration comprises an upper wing, a lower wing and a plurality of parallel distributed deformation mechanisms, wherein the upper wing and the lower wing are connected through the deformation mechanisms; each deformation mechanism comprises a connecting strut and 1 to 2 motion mechanisms; a drive mechanism and a locking device are arranged on each motion mechanism which is fixed on the upper wing or the lower wing; one end of the connecting strut is mechanically connected with the motion mechanism, while the other end of the connecting strut is mechanically connected with the motion mechanism or fixedly connected with the upper wing or the lower wing; the drive mechanism drives the motion mechanism to drive the connecting strut to ensure that the upper wing and the lower wing rotate in 0 to 180 degrees in the course direction and the height direction; and when the upper wing and the lower wing move to a set position, the locking device locks the motion mechanism, and positions of the upper wing and the lower wing are fixed. Regarding the wing configuration mode of a solar plane, the deformable biplane configuration is adopted, compared with single plane configuration, under a condition that the same wing type, the same wingspan and the same aspect ratio of a single wing are adopted, through the deformable biplane configuration, the takeoff weight can be increased, the effective load can be increased, the induced drag of the wings can be reduced, and the area of a solar cell panel can be increased, so that the solar energy absorption capacity can be improved, and the energy consumption of night flight can be reduced.

In order to overcome the problems of paint cracking and welding seam fatigue caused by insufficient rigidity and strength of existing car door and window structures, the present invention provides a car door and window frame structure, including door inner panels, door outer panels, window frame front components, window A frame rear assembly, a waistline reinforcement assembly and an upper sash, the sash front assembly includes a sash front outer panel and a sash front inner panel overlapping each other, the sash front outer panel and the sash front A first cavity is formed between the inner panels at the front of the window frame, the rear assembly of the window frame includes an outer panel at the rear of the window frame and an inner panel at the rear of the window frame which overlap each other, the outer panel at the rear of the window frame and the outer panel of the window frame A second cavity is formed between the inner panels at the rear of the window frame. At the same time, the invention also discloses an automobile comprising the above-mentioned vehicle door and window frame structure. The car door and window frame structure provided by the invention can ensure sufficient connection rigidity and strength of the window frame, and avoid paint cracking and sheet metal rusting caused by solder joints and seam welding cracks.
