The invention discloses a design method for a narrow area structure of a ship, and the method specifically comprises the following steps: S1, determining the minimum distance between a sharp corner of the narrow area and a longitudinal bone of a main deck, and determining the minimum distance between the sharp corner of the narrow area and the longitudinal bone on an inclined plate or a curved surface; s2, when the minimum value of the minimum distance between the sharp corner of the narrow area and the longitudinal bone of the main deck and the minimum distance between the sharp corner of the narrow area and the longitudinal bone on the inclined plate or the curved surface is smaller than 350 mm, the longitudinal bone at the uppermost end of the inclined plate or the curved surface is replaced with a transverse toggle plate; s3, the connection sizes of the transverse toggle plate and the longitudinal bone of the main deck and the longitudinal bone on the inclined plate or the curved surface are determined; and the transverse toggle plate is mounted in a narrow area. Longitudinal ribs are replaced by the transverse toggle plates, so that the welding complexity of a narrow area of a ship is reduced, a curved surface profile is omitted, the length of a welding seam is reduced, and the production cost is reduced.

The utility model provides a frame longitudinal beam, a frame structure and a vehicle. The frame longitudinal beam comprises a longitudinal beam body and an energy absorption piece arranged at the front end of the longitudinal beam body in the front-back direction of the whole vehicle. Wherein the longitudinal beam main body and the energy absorption piece are tubular, extend in the front-back direction of the whole vehicle, are integrally formed and are connected in an inserted mode. According to the frame longitudinal beam disclosed by the utility model, the longitudinal beam main body and the energy absorption piece are integrally formed, so that the number of parts of the frame longitudinal beam can be reduced, the welding length can be reduced, the precision and the force transmission effect of the frame longitudinal beam can be improved, and the rigidity and the strength of the frame longitudinal beam can be improved; therefore, the overall collision safety and durability of the frame can be improved; and the energy-absorbing piece is connected with the longitudinal beam main body in an inserted manner, so that the energy-absorbing piece is convenient to replace, and the maintenance cost of the frame longitudinal beam can be reduced.

This utility model discloses an IP54 protection rating lithium battery charger door panel structure, relating to the technical field of lithium battery charger door panels. The structure includes a charger door panel, an inner wall with a door lock, a cable routing groove fixedly connected to the inner wall of the door panel away from the door lock, a mounting component in the middle of the door panel, and a sealing component at the rear end. This utility model achieves reduced welding workload and improved work efficiency through folded edges and connecting components. The frame for mounting on the inner wall of the charger door panel uses a process of recessed folded edges on all four sides plus four connecting components for welding. While meeting waterproofing requirements, this greatly reduces the welding length, improves the aesthetic appearance of the door panel, and prevents deformation caused by prolonged heat exposure, while also reducing the workload of grinding the weld joints.

The utility model discloses a fuel tank structure for a large-tonnage loader, which belongs to the technical field of engineering machinery accessories and comprises a closed fuel tank main body formed by welding a U-shaped top plate and a U-shaped bottom plate, non-collinear mounting brackets are arranged on two sides of the fuel tank main body, and one side of the fuel tank main body is further connected with an oil filling pipe assembly capable of realizing flexible transition; and a first supporting oil baffle plate and a second supporting oil baffle plate are also arranged in the oil tank main body. The closed oil tank formed by welding the U-shaped top plate and the U-shaped bottom plate is small in welding seam number and short in welding seam length; a plurality of mounting brackets with height difference can relieve larger acceleration impact between the fuel tank main body and the mounting brackets; the flexible transition oil filling pipe assembly can reduce the pulling of lever force formed when the oil filling pipe extends outwards to the oil tank main body; the two supporting oil blocking partition plates welded to the bottom plate of the oil tank body can enhance the overall strength of the bottom plate, slow down the situation that fuel rapidly flows to the other side when a loader goes uphill and downhill, and avoid engine flameout caused by fuel suction.

This utility model provides a passive drainage structure for TPO roofs, relating to the field of roof drainage structures. It includes a strip-shaped drainage gutter and a siphon rainwater hopper. The drainage gutter, from bottom to top, comprises a galvanized steel plate, a vapor barrier, an insulation layer, and TPO roll material. The siphon rainwater hopper, from bottom to top, comprises an assemblable rainwater hopper support, a rainwater hopper base, and a guide hood body. The siphon rainwater hopper of this utility model is welded and fixed to the galvanized steel plate via the rainwater hopper support, avoiding the need to drill holes in the original insulation layer to reserve installation positions for the rainwater hopper, thus reducing damage to the gutter insulation layer and other structures. This utility model uses connecting supports welded to the galvanized steel plate, which, compared to the original full welding of the bottom of the siphon rainwater hopper, effectively reduces the welding length, improves construction efficiency, and greatly reduces gutter deformation caused by welding, improving construction quality and the appearance of the finished product.
