ActiveCN118418538BImprove energy absorptionlight weightLamination ancillary operationsSynthetic resin layered productsTransfer moldingResin bonding
This invention relates to a one-piece molded Whipple's Shield impact protection structure textile composite material and its preparation method. The product comprises, from top to bottom, an impact-facing fabric layer, a spacer fabric layer, and a back fabric layer. The impact-facing fabric layer is a single-layer or multi-layer fabric, with adjacent layers bonded together by resin. The spacer fabric layer is a hollow multi-layer structure consisting of a top layer, a bottom layer, and a spacer layer. The back fabric layer is also a multi-layer fabric, with adjacent layers bonded together by resin. The spaces between the impact-facing fabric layer and the top layer of the spacer fabric layer, as well as between the bottom layer of the spacer fabric layer and the back fabric layer, are filled with resin. Resin is impregnated between the back fabric layer, the spacer fabric layer, and the impact-facing fabric layer using a vacuum-assisted resin transfer molding process. After impregnation, the vacuum is removed, and the product is cured and demolded to obtain the final product. This invention features a simple preparation method; the product has high energy absorption, low specific gravity, high damage tolerance, and good impact protection performance.

Anti-collision beam assembly and vehicle provided with same
ActiveCN224476908UImproved impact protectionAvoid the problem of large length restrictionsControl theoryMechanical engineering
This application relates to the field of vehicle body technology and provides a crash beam assembly and a vehicle equipped with it. The crash beam assembly includes a crash beam and energy-absorbing boxes disposed at both ends near the crash beam. Each end of the crash beam has a vehicle body connection portion, and both ends of the crash beam form a vehicle body connection end directly connected to a longitudinal beam of the vehicle body. The energy-absorbing boxes at each end are connected to the same end of the vehicle body connection end, and each energy-absorbing box is connected to the side of the same end of the vehicle body connection end facing away from the longitudinal beam of the vehicle body. This application allows for maximum design space for the energy-absorbing boxes, which helps to increase the energy-absorbing length of the energy-absorbing boxes, improve the energy-absorbing effect of the energy-absorbing boxes, and thus enhance the collision protection effect of the crash beam assembly.

Protective structure of rotary power device
PendingCN121871838AImproved impact protectionImprove the protective effectPropellerStructural engineering
The invention discloses a protective structure of a rotary power device, which relates to the technical field of unmanned equipment accessories and comprises a protective net assembly and a connecting assembly. The protective net assembly is in an ellipsoid shape and used for being arranged outside a propeller of the rotating power device in a covering mode. A plurality of through holes which are uniformly distributed are formed in the peripheral side of the protective net assembly, a flow guide structure is further arranged on the inner side of the protective net assembly, and the flow guide structure is configured to guide fluid to flow in the preset direction when the propeller rotates so as to discharge impurities in the through holes; the connecting assembly is used for fixing the protective net assembly to a protected device. Based on the technical scheme disclosed by the invention, the collision protection capability and the equipment safety can be improved, self-cleaning can be realized, the flow resistance can be reduced, the endurance time of the equipment can be prolonged, and the anti-winding effect can be greatly improved.

ActiveCN118977858Bimprove postural stabilityEasy to installPower plant fuel tanksFuel tank safety measuresFlight vehicleClassical mechanics
The present invention relates to the technical field of longitudinal unmanned helicopters, and discloses an anti-static and anti-vibration fuel tank for helicopters. A plurality of groups of inner baffles are equidistantly installed in the fuel tank body in a segmented shape through bonding perforated plates. The folding direction of the inner baffles is perpendicular to the blocking surface of the adjacent inner baffles, which can effectively reduce the oil ripples in the front and rear and up and down directions, and weaken the influence of the oil ripples on the attitude of the aircraft. The segmented inner baffles are connected by conductive connecting pieces arranged on the upper part, so that the upper ends of the inner baffles are connected into a whole, which can quickly and effectively release static electricity. The fuel tank body is installed by means of an installation box seat, which not only provides a stable support but also effectively improves the impact protection of the fuel tank. A blowing heating component is arranged on the side of the installation box seat, which can realize rapid preheating and heating of the aircraft oil circuit in severe cold weather, and the heating structure has no direct contact with the fuel tank body, which greatly improves the working safety of the device.
