Technical Field
[0001] The present invention relates to the technical field of logistics and transportation equipment, and in particular to an automatic loading and unloading device for a truck compartment. Background Art
[0002] In the field of logistics and transportation, loading and unloading operations in truck compartments are one of the key links that affect transportation efficiency. Traditional loading and unloading methods mainly rely on manual operation or the use of auxiliary equipment such as forklifts, which is not only time-consuming and labor-intensive, but also has many inconveniences in narrow or complex working environments. Especially in scenarios where frequent loading and unloading of goods is required, the low efficiency of traditional methods is particularly prominent, increasing logistics costs and time consumption. In the prior art, some automated loading and unloading devices have been proposed, such as conveyor belts, hydraulic lifting platforms or robotic arms. However, these devices often have disadvantages such as complex structure, large space occupied in the compartment, and high installation and maintenance costs. In addition, some devices are prone to vibration or impact during the loading and unloading process, which may cause damage to the goods and affect transportation safety. Therefore, how to simplify the device structure, reduce the difficulty of installation and maintenance, and ensure the smoothness of cargo handling while ensuring loading and unloading efficiency has become a technical problem to be solved in this field.
[0003] In response to the above problems, the present invention proposes the need for an automatic loading and unloading device for truck compartments that has a simple structure, efficient loading and unloading, and is easy to integrate, so as to improve the level of automation in logistics transportation, reduce manual intervention, and ensure the efficiency, safety, and reliability of cargo handling. Summary of the Invention
[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an automatic loading and unloading device for a truck compartment, comprising a truck compartment, a movable carrying device and a driving device, characterized in that: the movable carrying device is installed in the compartment guide rail of the truck compartment through a connecting plate, and is driven by the driving device to slide longitudinally along the guide rail; an inflatable carrying plate is provided on the movable carrying device, which lifts the cargo by inflation so that the carrying plate moves relative to the cargo, and then the driving device drives the movable carrying device body to slide to push the cargo in and out of the compartment, thereby realizing automatic loading and unloading.
[0005] The movable carrying device adopts an inflatable carrying plate as the cargo carrying component. The inflatable carrying plate is fixedly installed on the upper surface of the connecting plate. The two ends of the connecting plate are connected to the guide rails set on the side walls of the carriage by a sliding fit, and the bottom of the connecting plate forms a rigid connection structure with the cylinder of the driving device.
[0006] The inflatable supporting plate adopts a nested structural design, including two components, an upper shell and a lower shell, wherein the upper shell can slide up and down along the lower shell, and an inflatable and deflated air cushion structure is provided between the upper shell and the lower shell, and the relative displacement between the upper shell and the lower shell is achieved by controlling the inflation and deflation state of the air cushion.
[0007] The driving device adopts a pneumatic driving mode. The two ends of the cylinder piston rod are connected to the truck chassis through a hinged mode and pass through the cylinder. The cylinder slides along the piston rod by adjusting the air pressure in the cylinder.
[0008] The inflatable load plate and the driving device cooperate with each other during loading and unloading. The inflatable load plate is first inflated and moved forward (backward) by the driving device. Then the inflatable load plate is deflated and moved backward (forward) by the driving device, thereby realizing the forward (backward) movement of the goods.
[0009] Compared with the prior art, the present invention has the following beneficial effects: The automatic loading and unloading device for the truck compartment realizes the automatic loading and unloading operation of goods by setting up a movable load-bearing device and utilizing the synergistic effect of an inflatable load-bearing plate and a connecting plate, significantly improving the loading and unloading efficiency, while reducing the need for manual intervention and lowering labor costs. It is particularly suitable for logistics scenarios with frequent loading and unloading.
[0010] The automatic loading and unloading device for the truck compartment adopts an inflatable load-bearing plate design, which realizes the smooth lifting and lowering of the goods through a uniform inflation and deflation process, avoids the impact or vibration in the traditional mechanical loading and unloading process, ensures the safety of the cargo handling process, and effectively prevents the risk of damage to the goods during the handling process. It is especially suitable for the transportation of fragile or delicate goods.
[0011] The automatic loading and unloading device for the freight car compartment is provided with a car compartment guide rail structure, which accurately defines the longitudinal movement trajectory of the connecting plate and effectively suppresses the adverse effects of vibration generated during the operation of the cylinder on the cargo. The automatic loading and unloading device for a truck compartment is integrated into the bottom of the truck compartment and can directly replace the traditional compartment floor, thereby completely maintaining the original cargo capacity.
[0012] The automatic loading and unloading device for a truck carriage comprises a truck carriage, a movable carrying device, and a driving device. It has a simple structure and is easy to install, which is conducive to adding the device to the original carriage design. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The movable load-bearing device adopts an inflatable load-bearing plate as a cargo-bearing component. The inflatable load-bearing plate is fixedly mounted on the upper surface of the connecting plate by welding. Sliders are provided at both ends of the connecting plate, and a V-shaped guide rail (or C-shaped, T-shaped guide rail) with an angle of 90° set on the side wall of the carriage forms an H7 / g6 level clearance fit, allowing an axial sliding tolerance of ≤0.08mm, and the bottom of the connecting plate forms a rigid connection structure with the cylinder of the driving device.
[0022] The two ends of the connecting plate act as sliders and form a H7 / g6 clearance fit with the V-shaped guide rail (or C-shaped, T-shaped guide rail) with an angle of 90° set on the side wall of the carriage, allowing an axial sliding tolerance of ≤0.08mm.
[0023] The cylinder of the driving device is rigidly connected to the connecting plate of the movable bearing device by welding or other means.

The upper shell can slide up and down along the lower shell, and the upper and lower shells can be connected by a V-shaped or T-shaped slide rail structure. An inflatable and deflated air cushion structure is arranged between the upper shell and the lower shell. The air cushion material can be selected from materials with strong pressure-bearing capacity such as aramid fiber. The relative displacement between the upper shell and the lower shell is achieved by controlling the inflation and deflation state of the air cushion.
