Luggage compartment door structure of big tourist coach

Abstract

The invention provides a luggage compartment door structure for a big tourist coach. Four lock bodies are fixedly connected with the upper side and the lower side of the left side edge and the right side edge of a compartment door respectively in pairs, two linkage devices are connected with the compartment door, each linkage device is connected with the two lock bodies through two lock pull rods, a cabin door lock opens the four lock bodies at the same time through linkage of the linkage devices and the lock pull rods, one end of a translation mechanism is hinged to the bus body framework of the big tourist coach, and the other end is hinged to the cabin door. A traditional framework design is abandoned, the latest design concept of framework and sheet metal part combination is introduced, a four-point locking double-lock-box mechanism is adopted for locking, and a manual translation mechanism and an air spring are adopted for auxiliary lifting in an opening and closing mode, so that the designed luggage compartment door structure is light in weight, high in rigidity, stable, convenient to open and close, free of site limitation, good in sealing effect, and high in the consistency of the appearance of a gantry.

Description

Technical field: [0001] The invention relates to a luggage compartment door structure for a large tourist. Background technique: [0002] The market has higher and higher requirements for passenger cars. In order to meet the needs of the passenger transport market, especially for tourist buses, in order to increase the number of passengers, the length of the body is constantly lengthening. difficult request. [0003] At present, in the domestic passenger car industry, fiberglass doors and aluminum doors are the mainstream in the market. Fiberglass doors are mainly used in front and rear panels, and the basic requirement for side doors is aluminum alloy. The aluminum alloy hatch has low density, corrosion resistance, good flatness, easy processing, and good plasticity. The production process adopts gluing or argon arc welding. Large tourist buses have high requirements on the consistency of the gantry curve of the body. When the size of the luggage compartment is large, the...

AI Technical Summary

Problems solved by technology

Large tourist buses have high requirements on the consistency of the gantry curve of the body. When the size of the luggage compartment is large, the thermal stress caused by welding, the size error of the installation, and the micro deformation caused by the opening and closing of the cabin door will cause the luggage compartment to be in contact with the side. The surrounding frame is not tightly fitted, causing dust and rainwater to enter the luggage compartment
