Description

Technical Field

[0001] The utility model relates to the field of truck carriage doors, and specifically, to a truck door panel assembly and a truck carriage. Background Art

[0002] A semi-trailer is a heavy transportation vehicle that connects a cargo carriage to a power truck head through a kingpin. Generally, a rear carriage door is provided at the rear end of the semi-trailer carriage. Common opening methods of the rear carriage door include double-leaf swing doors and flip doors. Among them, the carriage door designed with a flip door can be flipped up or down, which is convenient for loading and unloading and transporting goods. The carriage door designed with double-leaf swing doors is like two large open wings, which can make the loading and unloading of goods simple and fast.

[0003] The invention patent application with the publication number of CN118386975A discloses a semi-trailer carriage door structure, including a door frame, fixed blocks, a flip door panel, and lock catch rings. There are two fixed blocks symmetrically fixed on the inner walls of both sides of the door frame. Opposite the top surface of the door frame, double-leaf door panels are rotatably connected to both fixed blocks; the flip door panel is rotatably installed on the inner wall of the bottom of the door frame, and the top surface of the flip door panel is in contact with the bottom surfaces of the two double-leaf door panels. Three rotating plates are rotatably connected to the inner surface of the flip door panel at equal intervals, and an extension mechanism for synchronously rotating the three rotating plates is arranged on the inner surface of the flip door panel; there are two lock catch rings symmetrically fixed on the outer surfaces of both sides of the door frame, and a locking mechanism cooperating with the lock catch rings is arranged on the outer surface of the end of the flip door panel away from the rotating plates. This semi-trailer carriage door structure is convenient for releasing the rotational locking and limiting effect between the flip door panel and the door frame, facilitating the synchronous unfolding and storage of the three rotating plates, improving the convenience of loading and unloading personnel getting on and off the vehicle and during cargo loading and unloading, and thus improving the loading and unloading efficiency when loading and unloading goods. However, this structure is complex and not convenient for separately controlling and disassembling the flip door panel and the double-leaf door panels. Summary of the Utility Model

[0004] In order to be able to quickly disassemble a truck door and, according to the nature of goods, increase the opening methods of the carriage door, the technical solution adopted by the utility model is: a truck door panel assembly, including an upper flip door and a lower flip door. An upper locking handle for hooking on a carriage column is arranged on the upper part of the upper flip door. Lower columns are respectively connected to both sides of the lower part of the upper flip door. The lower flip door is arranged between a pair of the lower columns. Lower locking handles for hooking on the lower columns are arranged on both sides of the upper part of the lower flip door. Open-type hinges for connecting to a chassis side beam are respectively arranged at the bottom of the lower columns and the bottom of the lower flip door.

[0005] The open hinge includes an inverted U-shaped flipping socket and a flipping hook for hooking the inverted U-shaped flipping socket. The flipping hook is fixed on the side beam of the chassis, and the top is obliquely open. The bottom of the lower vertical column and the bottom of the lower flipping door are respectively provided with the inverted U-shaped flipping sockets, and a rotating shaft for the flipping hook to hook is arranged in the inverted U-shaped flipping socket.

[0006] Based on the above, the width value of the lower flipping door is smaller than the width value of the upper flipping door.

[0007] Based on the above, a handle card hole is opened on the lower vertical column corresponding to the lower locking handle.

[0008] Based on the above, in order to increase the flipping stability, a plurality of the open hinges are arranged at the bottom of the lower flipping door, and the plurality of open hinges are arranged at equal intervals.

[0009] Based on the above, the height value of the lower flipping door is smaller than the height value of the upper flipping door.

[0010] The present utility model further provides a freight car carriage, and the freight car carriage is installed with the above-mentioned freight car door panel assembly.

[0011] The present utility model has substantial features and progress compared with the prior art. Specifically, for the freight car door panel assembly and the freight car carriage provided by the present utility model, the freight car door panel assembly is designed into a structure of a door within a door, so that the freight car door has two opening modes, one is to open integrally, and the other is to only open the lower flipping door. Thus, according to the nature of the goods, the opening mode can be reasonably selected to realize the rapid loading and unloading of various goods, with convenient operation, safety and reliability. At the same time, by designing a specific open hinge for the freight car door panel assembly, the panel structure can also be quickly disassembled, and the part above the chassis can be quickly removed from the chassis as a whole, so that the chassis becomes a flatbed truck to adapt to loading larger and different goods. The freight car door panel assembly is convenient to use, install and disassemble. Description of the Drawings
