This invention discloses a bending fatigue enhancement structure for flat cables, relating to the field of flat cable technology. It includes a wear-resistant outer sheath, a flexible skeleton, an elastic inner liner, and a composite conductor bundle. The wear-resistant outer sheath covers the flexible skeleton, with bending stress cores at the outer ends. The flexible skeleton is internally covered by an elastic inner liner, which contains two spaced-apart composite conductor bundles. The flexible skeleton has grooves filled with an anti-oxidation coating layer, within which the bending stress cores are fixed. The interior features stress-dispersing adhesive grooves intersecting with the grooves, and high-toughness reinforcing ribs with abrasion-resistant protective sleeves are installed at the four corners. The elastic inner liner has a water-blocking tape wrapping layer on its outer side and a flame-retardant isolation layer inside. The composite conductor bundles are wrapped with cable core fixing rings and an electromagnetic shielding layer. This structure, through multiple stress dispersion, protection, and positioning designs, significantly improves the cable's bending fatigue resistance, ensuring stable transmission and safe operation, and is suitable for high-frequency bending scenarios.

This invention discloses a magnesium-aluminum alloy for seat brackets, its preparation method, a seat bracket, and a vehicle, belonging to the field of automotive technology. Based on the total weight of the magnesium-aluminum alloy, its chemical composition, calculated by mass percentage, includes: aluminum: 2.5%-4.0%; zinc: 2.0%-3.5%; tin: 0.8%-1.5%; calcium: 0.3%-0.6%; cerium: 0.05%-0.2%; manganese: 0.2%-0.4%; with the remainder being magnesium and unavoidable impurities. By controlling the aluminum content to a low range, the coarse, brittle network phase β−Mg is suppressed at its source. 17 Al 12 The introduced calcium element preferentially reacts to form the Al2Ca phase, thereby maximally suppressing the formation of β−Mg. 17 Al 12 The formation of the phase, along with the introduction of tin, results in the formation of the high-hardness Mg2Sn phase with magnesium, which serves as the main precipitation strengthening phase. Trace amounts of cerium act as a synergistic phase morphology regulator, influencing the morphology of the Al2Ca and Mg2Sn phases during solidification and pinning them to the grain boundaries. Through this multi-phase regulation, the alloy achieves high strength while avoiding the toughness loss caused by the presence of a large number of brittle phases in traditional magnesium alloys.

This utility model relates to the field of DHA algal oil filtration technology, and more particularly to a filtration device for DHA algal oil, including a housing, a moving mechanism on the side of the housing, a thawing mechanism disposed within the moving mechanism, a first filtration mechanism fixedly installed below the thawing mechanism, and a second filtration mechanism fixedly installed below the first filtration mechanism. This utility model employs a split-type thawing box design in the thawing mechanism, which can quickly and evenly melt solidified algal oil raw materials, avoiding DHA oxidation loss caused by localized overheating. The moving mechanism, in conjunction with a sliding groove, allows for flexible pulling of the thawing box. The solenoid valve of the first filtration mechanism can precisely control the coarse filtration flow rate, while the second filtration mechanism further removes micron-sized impurities through silk mesh gradient filtration. The synergistic effect of the two stages ensures high light transmittance and low acid value of the algal oil. Real-time monitoring of the filtration process is achieved through a glass observation window and a weighing plate, and support legs and anti-slip pads enhance the equipment's resistance to displacement in vibration environments.
