Description

Technical Field

[0001] This utility model relates to the field of vehicle body technology, and in particular to an adjustable vehicle body for trailers. Background Technology

[0002] A trailer is a common means of transportation. It is a type of unpowered road vehicle that relies on other vehicles to tow it to move and operate normally. It is used to carry goods. A semi-trailer has its axle located behind the vehicle's center of gravity and is equipped with a coupling device that can transmit horizontal or vertical forces to the tractor.

[0003] For example, the adjustable trailer body disclosed in Chinese Patent No. CN218640744U works as follows: "It includes a trailer body, which has a placement cavity and a transverse cavity. The transverse cavity is located below the placement cavity. A drive motor is installed on the right side of the trailer body. The output shaft of the drive motor extends into the transverse cavity and is fixedly connected to a threaded rod. The two ends of the threaded rod are rotatably connected to the left and right inner walls of the transverse cavity. The upper end of the transverse cavity has a strip-shaped opening. A slider is threaded onto the threaded rod, and the slider is slidably connected to the inner wall of the transverse cavity. This trailer body can be used as a normal trailer body under normal conditions." When transporting two different types of goods, the partition can be raised to separate them. The position of the partition can be adjusted according to the quantity of goods, so that the space inside the compartment can be fully utilized. It is also equipped with a liftable vertical panel, which facilitates the overall storage of the partition and ensures that the two spaces are completely isolated, so that the two goods will not affect each other. However, the partition can only achieve single vertical obstruction, and the division method is fixed. It cannot flexibly adjust the division method according to the size and shape of the goods. It cannot achieve multi-area division of the compartment space, and the flexibility and adaptability of space division are insufficient, making it difficult to cope with diverse cargo loading scenarios. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an adjustable trailer body with a spatial barrier function of the dividing component. It can divide the overall space of the trailer body into multiple independent storage areas to meet the classification and storage needs of goods of different specifications and types. The dividing position and area size can be flexibly adjusted according to the amount of goods without disassembling or replacing additional parts.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable trailer body, including a trailer body, an internal space for the trailer body, two rotating and closing doors rotatably disposed on one side of the opening of the trailer body, two movable slots disposed on the bottom surface of the internal space for the trailer body, a lead screw driven by a motor disposed inside the movable slot, a movable block movably disposed inside the movable slot, the movable block being threaded onto the outside of the lead screw, a receiving plate fixedly connected above the movable block, and a dividing component for separating the trailer body disposed above the receiving plate.

[0006] As a preferred technical solution of this utility model, the dividing component includes an upper rotating plate and a lower rotating plate. A fixed shaft is fixedly arranged at the midpoint above the receiving plate. The upper rotating plate and the lower rotating plate are rotatably arranged around the fixed shaft.

The stretching plate is movably arranged inside the stretching grooves. Fixing plates are fixedly arranged on both sides of the upper rotating plate and the lower rotating plate. Fixing blocks are fixedly arranged on both sides of the stretching plate. Sliding grooves adapted to the fixing blocks are provided on both sides of the upper rotating plate and the lower rotating plate. The fixing plates and fixing blocks are fixed by bolts.

[0008] As a preferred embodiment of this utility model, a gap is left between the receiving plate and the bottom surface of the vehicle space, and a gap is left between the upper rotating plate and the lower rotating plate and the inner wall of the vehicle space.

[0009] As a preferred embodiment of this utility model, the maximum rotation angle between the upper rotating plate and the lower rotating plate is 90°.

[0010] As a preferred embodiment of this utility model, a cover plate is fixedly installed above the inside of the moving groove, and the cover plate penetrates the moving block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a receiving plate driven by a motor, lead screw, and moving block within the onboard space of the trailer body, and a dividing component above the receiving plate, flexible division and dynamic adjustment of the interior space of the trailer are achieved.

[0014] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0015] Please refer to Figure 1-3As shown, this utility model provides an adjustable trailer body, including a trailer body 10. The trailer body 10 has an internal space 11. The internal space 11 has two rotating closing doors 12 rotatably arranged on the opening side of the trailer body 10. The internal bottom surface of the internal space 11 has two moving slots 20. The moving slots 20 are equipped with lead screws 21 driven by motors. The moving slots 20 are movably arranged with moving blocks 23. The moving blocks 23 are threaded around the lead screws 21. A receiving plate 24 is fixedly connected above the moving blocks 23. A dividing component that can separate the internal space 11 is provided above the receiving plate 24.

[0016] In this case, by installing a receiving plate 24 driven by a motor, a lead screw 21, and a moving block 23 within the vehicle space 11 of the trailer body 10, and a dividing component above the receiving plate 24, flexible division and dynamic adjustment of the interior space of the trailer are achieved. The receiving plate 24 can move smoothly along the moving groove 20 with the help of the lead screw 21, causing the dividing component to change its position within the vehicle space 11. Combined with the spatial barrier effect of the dividing component, the overall space of the trailer can be divided into multiple independent storage areas to meet the classification and storage needs of goods of different specifications and types. The dividing position and area size can also be flexibly adjusted according to the amount of goods without disassembling or replacing additional parts. The space utilization method is flexible and versatile, effectively improving the adaptability and practicality of the trailer trailer and solving the problem that the space of the traditional fixed trailer cannot be flexibly adjusted.

[0017] The dividing assembly includes an upper rotating plate 26 and a lower rotating plate 27. A fixed shaft 25 is fixedly installed at the midpoint above the receiving plate 24. Both the upper rotating plate 26 and the lower rotating plate 27 are rotatably arranged around the fixed shaft 25. Rotary motors for driving the upper rotating plate 26 and the lower rotating plate 27 to rotate are provided at both ends of the fixed shaft 25. Extension components for extending their length are provided inside the upper rotating plate 26 and the lower rotating plate 27.

[0018] By designing the partition component as a combination structure of an upper rotating plate 26, a lower rotating plate 27, and a fixed shaft 25, and using the rotary motors at both ends of the fixed shaft 25 to drive the two rotating plates to rotate respectively, the flexibility of space partitioning is further optimized. The upper rotating plate 26 and the lower rotating plate 27 can rotate independently or synchronously. When rotating, the vehicle space 11 can be partitioned. With the length adjustment function of the extension component, it can adapt to the space partitioning requirements of different widths and heights, and can also meet the partitioning and isolation of multiple batches of small items. This greatly improves the functional diversity of the partition component and makes the planning of the vehicle space more in line with the actual loading scenario.

[0019] The extension assembly includes a stretching plate 29, and stretching grooves 28 are formed inside the upper rotating plate 26 and the lower rotating plate 27. The stretching plate 29 is movably arranged inside the stretching grooves 28. Fixing plates 210 are fixedly arranged on both sides of the upper rotating plate 26 and the lower rotating plate 27. Fixing blocks 211 are fixedly arranged on both sides of the stretching plate 29. Sliding grooves adapted to the fixing blocks 211 are formed on both sides of the upper rotating plate 26 and the lower rotating plate 27. The fixing plates 210 and the fixing blocks 211 are fixed by bolts 212.

[0020] By setting the extension components of the stretching groove 28 and the stretching plate 29 in the rotating plate, and combining the fixing structure of the fixing plate 210, the fixing block 211 and the bolt 212, the length of the rotating plate can be adjusted and locked securely. The stretching plate 29 can freely extend and retract along the stretching groove 28. The effective blocking length of the upper rotating plate 26 and the lower rotating plate 27 can be flexibly adjusted according to the width of the carriage, ensuring that the dividing components can fit tightly with the inner wall of the carriage and avoid gaps between the partitions that could cause the goods to shift. The bolt 212 fixing method is simple to operate and reliable to connect. It can keep the position of the stretching plate 29 stable during the bumpy transportation of goods and prevent the length from shifting due to vibration. This not only improves the adaptability of the extension components, but also ensures the stability of the spatial division. At the same time, the structure is simple, the manufacturing cost is low, and it is easy to maintain and replace later.

[0021] There is a gap between the receiving plate 24 and the bottom surface of the vehicle space 11, and there is a gap between the upper rotating plate 26 and the lower rotating plate 27 and the inner wall of the vehicle space 11.

[0022] By reserving gaps between the receiving plate 24 and the bottom surface of the vehicle space 11, and between the rotating plate and the inner wall of the vehicle space 11, structural interference problems are effectively avoided, ensuring the smooth operation of each component. The gap between the receiving plate 24 and the bottom surface can prevent the receiving plate 24 from rubbing against the bottom surface when it moves, reducing component wear. The gaps between the upper rotating plate 26, the lower rotating plate 27 and the inner wall provide sufficient room for their rotation and the extension and retraction of the stretching plate 29, avoiding obstruction of rotation and extension due to manufacturing errors or assembly deviations, ensuring the stable and reliable adjustment function of the segmented components, and improving the smooth operation and durability of the overall structure.

[0023] The maximum rotation angle of the upper rotating plate 26 and the lower rotating plate 27 is 90°.

[0024] By limiting the maximum rotation angle of the upper rotating plate 26 and the lower rotating plate 27 to 90°, the effectiveness of space division is ensured while also taking into account structural rationality and operational safety. The 90° rotation limit ensures that the rotating plates are positioned precisely to divide the vehicle space 11, achieving the optimal space division effect and preventing damage from collisions between the upper rotating plate 26, the lower rotating plate 27, and the inner wall or other components of the vehicle space 11 due to excessive rotation angle. At the same time, the clear rotation angle limit prevents the rotating plates from rotating excessively due to operational errors or motor overload, protecting the transmission structure of the rotating motor and the fixed shaft 25, reducing the failure rate, making the space division operation more controllable, and improving the safety and stability of the equipment.

[0025] A cover plate 22 is fixedly installed inside the upper part of the moving slot 20, and the cover plate 22 passes through the moving block 23.

[0026] By setting a baffle 22 that penetrates the moving block 23 inside the moving groove 20, a good protective and guiding function is achieved. The baffle 22 can effectively block the debris of the goods from entering the moving groove 20, prevent impurities from adhering to the surface of the lead screw 21 or jamming the moving block 23, ensure the smooth transmission of the lead screw 21, and reduce the wear and failure risk of components. At the same time, the baffle 22 forms a precise guide for the through structure of the moving block 23, ensuring that the moving block 23 moves smoothly and linearly along the moving groove 20, preventing it from deviating or shaking during the movement, improving the stability and positional accuracy of the receiving plate 24, thereby ensuring the spatial positioning accuracy of the dividing component and extending the service life of the overall structure.
