[0002] Semi-trailers are primarily used to transport bulky, difficult-to-break-down cargo, such as excavators. Barrier-type trailers are more suitable for transporting fresh goods, such as vegetables and fruit. Box-type trailers are more suitable for transporting bulk cargo and moisture-resistant, valuable goods. Siderails are typically installed on both sides of a semi-trailer to protect the cargo from falling due to vibration during transport.

[0003] In the prior art, the Chinese utility model patent with authorization announcement number CN221914423U discloses a semi-trailer with adjustable tailgate, including a vehicle body, side panels are symmetrically fixedly connected on both sides of the top end of the vehicle body, a cavity is provided inside the side panel, a telescopic plate is slidably connected inside the cavity, and a telescopic assembly is provided at the bottom end of the telescopic plate, the telescopic assembly includes a transmission shaft rotatably connected to the internal cavity of the side panel, the outer end of the transmission shaft is provided with a threaded ring, and the outer end of the threaded ring is threadedly connected to a connecting column. The utility model relates to the technical field of semi-trailers; the semi-trailer with adjustable tailgate rotates in the cavity inside the side panel through the transmission shaft, so that the two connecting columns move toward each other at the threaded ring at the outer end of the transmission shaft, thereby causing the two rotating rods to flip toward each other, and then drive the card plate and the telescopic plate clamped thereto to slide inside the side panel. At this time, the telescopic plate is extended to increase the height of the side panel, which is simple to operate and more labor-saving when adjusting the height of the side panel.

[0004] Compared with the existing technology, there are problems: the existing semi-trailer with partially adjustable sidewalls can only adjust the height of the trailer sidewall as a whole, and cannot adjust the trailer sidewall according to the different cargo heights at different positions of the trailer, resulting in a large waste of space above the cargo and inconvenience in fixing.

[0005] Therefore, there is a need for a semi-trailer with adjustable tailgate. Utility Model Content

[0010] As a further solution of the present invention: a pull ring is provided under the workbench for driving the workbench to move.

[0011] As a further solution of the present invention: a plurality of rollers are provided on the outer wall of the workbench to reduce the friction between the workbench and the bevel gear A.

[0012] As a further solution of the present invention: a slide groove is provided at one end of the lifting plate, and a plurality of limit plates are evenly provided on the inner wall of the side plate for lateral limitation of the lifting plate.

[0013] As a further solution of the present invention: a groove is provided at one end of the lifting plate, and a convex strip is provided at the other end of the lifting plate, and the groove cooperates with the convex strip to ensure that the multiple lifting plates are in the same plane.

[0015] 1. Pull rings are provided, and by pulling the pull rings at different positions, the workbench is driven to move along the limit slots. Under the rotation of multiple rollers, the bevel gear A is pushed to move along the square rod, thereby selecting the trailer side panels at different positions. Driven by the servo motor, the power is transmitted to the trailer side panels at different positions through the square rod, thereby adjusting the trailer side panels according to the different cargo heights at different positions of the trailer, avoiding the waste of a large space above the cargo, and improving the convenience of fixing cargo on the semi-trailer with adjustable side panels;

[0016] 2. By providing a bevel gear B, under the driving action of the bevel gear A at different positions, the bevel gear B drives the screw rod to rotate, and the screw rod drives the lifting plate to slide along the inner wall of the side plate, thereby automatically adjusting the height of multiple trailer side panels, thereby improving the accuracy of the height adjustment of the trailer side panels. The lifting plates on both sides drive the elastic straps to rise and fall at both ends, and use the elasticity to fix the goods at different heights, thereby ensuring the stability of the semi-trailer with adjustable side panels for cargo transportation.
