AI Technical Summary
The existing wing lifting structure lacks a locking function, which makes the wing unstable after lifting, posing a safety hazard. In addition, the lack of a sealing design allows humid air from the outside to enter the compartment and affect the quality of the cargo.
The system combines locking and sealing components. A servo motor drives a screw to rotate, which in turn causes a toothed plate to engage with a locking shaft. The bracket and the locking shaft generate friction to fix the wing plate. An electric push rod pushes a push wheel to make the trapezoidal block control plate fit tightly against the wing plate, eliminating gaps.
This design achieves stable fixation of the wing panels, preventing accidental closure and improving safety. It also eliminates gaps, protecting goods from external humid air and ensuring cargo quality.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle wing plate technology, and in particular relates to wing plate lifting structure. Background Technology
[0002] Wings are lifting and lowering structures on both sides of a truck bed. They are usually driven by a hydraulic system and are used to expand the loading and unloading area. Their design purpose is to improve loading and unloading efficiency, and they are especially suitable for the rapid loading of bulk or large goods. The raised wings can increase the unloading area, making it easier for forklifts or manual handling of goods. They are an important functional component of freight vehicles.
[0003] Existing wing lifting structures typically include a fixed base, a lifting arm, and a drive unit. One end of the lifting arm is connected to the base via a hinge, and the other end is connected to the wing. The drive unit acts on the lifting arm to provide lifting force for deploying and closing the wing.
[0004] However, this structure has its flaws. On the one hand, due to the lack of an effective locking function, the wing panels cannot be stably fixed after being lifted, and are prone to accidental closure under external force, increasing the risk. On the other hand, there is no sealing design between the wing panels and the container, leaving obvious gaps. During cargo transportation, external moisture can easily enter the container through these gaps, affecting the quality of the cargo and making it impractical.
[0005] To address these issues, we have developed a wingplate lifting structure. Utility Model Content
[0006] The purpose of this utility model is to provide a wing-plate lifting structure. By combining locking and sealing components, it solves the problem that existing wing-plate lifting structures lack locking and sealing functions, which can easily increase the risk during use. Furthermore, during transportation, gaps can allow humid air from the outside to enter the vehicle compartment, affecting the quality of the goods.

The door 6 facilitates the loading and unloading of goods. The positioning rod and positioning sleeve can increase the stability of the toothed plate 37 during movement.
[0030] The working principle of this utility model is as follows: When the wing plate body 2 needs to be lifted, the drive motor 42 starts, causing it to drive the rotating shaft 43 to rotate. The winding roller 44 on the rotating shaft 43 winds up the steel wire rope 45. The steel wire rope 45 pulls the wing plate body 2 to rotate and unfold around the hinge, realizing the lifting operation. During the lifting process, the rotating shaft 43 drives the locking shaft 32 to rotate synchronously, and the gear 33 on the locking shaft 32 rotates accordingly. After the lifting is completed, the servo motor 34 drives the screw 35 to rotate, controlling the threaded sleeve 36 to drive the toothed plate 37 to mesh with the gear 33. At the same time, the threaded sleeve 36 pushes the bracket 38 and the friction sleeve 39 closer to the locking shaft 32, so that the friction sleeve... Friction is generated by the tight contact between the 39 and the surface of the locking shaft 32. The double locking prevents the locking shaft 32 from rotating accidentally, thereby fixing the position of the wing body 2, preventing it from closing accidentally, and improving safety. When the wing body 2 is in the closed state, the electric push rod 52 pushes the push wheel 53 to move upward. The push wheel 53 squeezes the trapezoidal block 54 to move it and controls the pressure plate 55 to compress the spring 56. The pressure plate 55 moves and pushes the squeezing block 57 to make the wing body 2 fit tightly with the frame 1, eliminating gaps, preventing the outside humid air from entering the interior of the car, protecting the quality of the goods, and avoiding the gap between the wing body 2 and the frame 1 that would cause moisture to affect the goods.
