Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of semi-trailers, in particular to a semi-trailer compartment. BACKGROUND

[0002] The semi-trailer is a trailer with an axle placed behind the center of gravity of the vehicle and equipped with a coupling device capable of transmitting horizontal and vertical forces to the towing vehicle. The semi-trailer is generally a three-axle semi-trailer, which is classified into many types such as an eleven-meter van semi-trailer, a thirteen-meter van, a low flatbed semi-trailer, etc. It is a heavy transport vehicle connected to the semi-trailer head through a towing pin.

[0003] When the semi-trailer compartment is loaded with goods and the goods are tilted to one side during driving, sudden turning, jolting, collision, etc., the goods are likely to be dumped to the side and hit the side plate, causing the side plate to be crushed and spilled outside the compartment, resulting in damage to the goods and posing a safety hazard to other vehicles and pedestrians on the road. SUMMARY

[0004] The purpose of the present application is to provide a semi-trailer compartment that can automatically reinforce the side plate and improve the crashworthiness of the side plate after the side plate is subjected to extrusion and impact.

[0005] The above technical purpose of the present application is achieved by the following technical solution: a semi-trailer compartment comprising a bottom plate, two side plates mounted on the bottom plate, a plurality of reinforcing assemblies provided between each side plate and the bottom plate, a sliding seat provided in the vertical direction on the side plate, an active rod hingedly connected to the sliding seat at the upper end, a hydraulic cylinder mounted on the bottom plate, and a lower end of the active rod hingedly connected to the hydraulic cylinder piston rod; the side plate is provided with a detection plate, a plurality of springs are connected between the side plate and the detection plate, a pressure sensor is mounted between the side plate and the detection plate, the semi-trailer compartment further comprises a controller, and the pressure sensor and the hydraulic cylinder are connected to the controller.

[0006] By adopting the above technical solution, the goods are fixed on the bottom plate, and the active rod is in a horizontal or nearly horizontal state, which does not affect the loading and unloading of the goods. When the goods are tilted to one side during transportation, the detection plate is extruded and impacted, the detection plate is close to the side plate, the pressure sensor detects the pressure value and sends a signal to the controller, the controller controls the hydraulic cylinder piston rod to move, the upper end of the active rod rises, the lower end moves close to the side plate, and the active rod is in an inclined state, thereby strengthening and reinforcing the side plate.

[0007] The side plate is further provided with a plurality of adjusting seats which are connected to the slide seat in a one-to-one correspondence, the adjusting seat is located above the slide seat, the adjusting seat and the slide seat are connected through a rope, the adjusting seat is provided with a guide slope, the movable plate is in contact with the guide slope and drives the adjusting seat to rise when the movable plate is forced to approach the side plate, the adjusting seat drives the slide seat to rise, and the bottom plate is provided with a containing groove for the movable rod.

[0008] By adopting the above technical scheme, when the detection plate is not subjected to extrusion impact, the movable rod is in a horizontal state in the containing groove, and in fact, it can also be slightly inclined upward. When the detection plate is subjected to extrusion impact, it is difficult to adjust the horizontal movable rod to an inclined state only by relying on the hydraulic cylinder. Therefore, the adjusting seat is designed creatively, and during the process of approaching the side plate after the detection plate is subjected to extrusion impact, the detection plate is in contact with the guide slope and drives the adjusting seat to rise, the adjusting seat drives the slide seat to rise a small distance through the rope, so that the movable rod changes from a horizontal state to an inclined state, and then the movable rod is continuously moved by the hydraulic cylinder.

[0009] The further setting of the present application is that the rope is a steel wire rope.

[0010] By adopting the above technical scheme, the steel wire rope is firm.

[0011] The further setting of the present application is that two reinforcing components are arranged between each side plate and the bottom plate, and the two reinforcing components are respectively arranged at the front end and the rear end of the side plate.

[0012] The further setting of the present application is that a plurality of guide columns are fixed in the inner side of the side plate, and the detection plate is provided with a plurality of guide holes, and the guide columns are inserted into the guide holes.

[0013] By adopting the above technical scheme, the guide columns and the guide holes are used for guiding the movement of the detection plate, and also can support the detection plate, so as to avoid the downward misalignment and falling of the detection plate relative to the side plate.

[0014] The present application has the beneficial effects that: by arranging the reinforcing component, when the goods are not tilted to the side, the movable rod of the reinforcing component is in the containing groove of the bottom plate, and does not affect the loading and unloading operation of the goods. When the goods are tilted to the side, the movable rod of the reinforcing component is in an inclined state and plays a reinforcing and reinforcing role on the side plate subjected to extrusion impact, so as to automatically reinforce the side plate and improve the anti-collision performance of the side plate.
