Description

Technical Field

[0001] This utility model relates to the field of refrigerated truck technology, specifically to a refrigerated truck with an unloading mechanism. Background Technology

[0002] Refrigerated trucks, as the core transportation tool of cold chain logistics, are widely used for transporting perishable goods such as frozen foods, dairy products, and fresh fruits and vegetables. Currently, unloading refrigerated trucks still mainly relies on manual handling, requiring staff to enter the refrigerated compartment and move the goods out one by one, which is cumbersome and labor-intensive.

[0003] To improve this situation, several auxiliary unloading solutions have emerged in the industry, but all have significant drawbacks: some refrigerated trucks attempt to use rail-mounted mobile trolleys inside the truck compartment for auxiliary unloading, such as the technology disclosed in CN201721043647.8 for a refrigerated truck. This requires first loading the goods onto the trolley, then pushing the trolley to the door for unloading. However, after unloading, the trolley must be manually pushed back to its original position before the next operation can begin. This frequent repositioning interrupts the unloading process, making continuous and efficient operation difficult. Furthermore, the trolley has limited carrying capacity, allowing only a small amount of goods to be transported at a time. When dealing with large quantities of goods, the overall efficiency improvement is limited, still requiring significant manual labor for handling.

[0004] Another approach involves fixing rollers to the floor of the refrigerated truck to reduce friction and facilitate cargo movement, as disclosed in CN201921010128.0, "Refrigerated Trucks for Convenient Loading and Unloading." However, rollers fixed to the floor always occupy space at the bottom of the truck. If goods are stacked on the rollers, the weight of the upper goods can easily press the lower layer against them, especially for fragile goods such as fruits, vegetables, and dairy products, which can easily cause packaging damage or spoilage. Reducing the stacking height to avoid compression would significantly waste the effective storage space of the refrigerated truck, reduce the amount of cargo transported per trip, and indirectly increase logistics costs.

[0005] In summary, existing refrigerated truck unloading assistance solutions are insufficient to meet the actual needs of cold chain logistics for efficient and safe unloading, necessitating a superior unloading mechanism to address these pain points. Therefore, this paper proposes a refrigerated truck equipped with an unloading mechanism. Summary of the Invention

[0006] The purpose of this invention is to provide a refrigerated truck with an unloading mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a refrigerated truck with an unloading mechanism, comprising a vehicle body, a refrigerated compartment mounted on the vehicle body, a plurality of independently foldable unloading components evenly mounted on the inner sidewall of the refrigerated compartment, and a plurality of compartment limiting components evenly mounted on the inner sidewall of the refrigerated compartment to restrict the position of the unloading components.

[0008] The refrigerated compartment is equipped with an external unloading assembly that can be flipped out of the refrigerated compartment on the side near the door. An external limiting assembly is installed on the upper inner side of the refrigerated compartment to restrict the position of the external unloading assembly.

[0009] Preferably, the unloading assembly inside the container includes a frame, with multiple first rollers rotatably connected to the inner side of the frame, two connecting plates symmetrically installed on one side of the frame, and a connecting seat installed on the inner wall of the refrigerated compartment, with the connecting seat rotatably connected to the connecting plate.

[0010] Preferably, the internal limiting component includes a mounting base, which is installed on the inner wall of the refrigerated compartment. A limiting baffle is rotatably connected to the mounting base. The frame has a folded edge on the side away from the connecting plate, and the folded edge is located between the limiting baffle and the inner wall of the refrigerated compartment.

[0011] Preferably, the external unloading assembly includes two support plates, and a plurality of second rollers are uniformly rotatably connected between the two support plates.

[0012] Preferably, the support plate includes a long plate and a short plate, the short plate is rotatably connected to the inner bottom wall of the refrigerated compartment, and the long plate is installed at one end of the short plate.

[0013] Preferably, the external limiting assembly includes a threaded cylinder and a threaded rod. The threaded cylinder is installed above the inner side wall of the refrigerated compartment, and the threaded rod passes through the long plate and is adapted to the threaded cylinder.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This refrigerated truck with an unloading mechanism, through the cooperation of independently foldable and retractable internal unloading components and foldable and connectable external unloading components, can specifically solve the unloading problems of existing refrigerated trucks, constructing a continuous channel for horizontal conveying inside the container and inclined conveying outside the container. The internal components can be unfolded as needed to avoid process interruption, significantly improving unloading efficiency and reducing manual handling. When the goods are fully loaded and close to the door, there is no need to fold down the internal components; only the external components are needed to shorten the unloading preparation time. When the goods are small and located deep inside the container, folding down the corresponding number of internal components forms a continuous conveying channel, avoiding the process of manually moving back and forth between the inside and outside of the container.

[0015] The components can be stored without unloading, allowing goods to be stacked directly on the flat bottom of the container, preventing fragile goods from being squeezed and damaged. The component storage does not occupy the core storage area of ​​the container, allowing goods to be stacked at the maximum load height, increasing the single transport volume and reducing logistics costs. At the same time, the overall operation is simple, and a single person can complete the unfolding and storage of the components. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-7 This utility model provides a technical solution: a refrigerated truck with an unloading mechanism, including a vehicle body 1. A refrigerated compartment 2 for storing goods requiring low-temperature preservation is fixedly installed on the cargo area of ​​the vehicle body 1. Multiple unloading components 3, which can be independently flipped and stored around connection points, are evenly installed on the inner sidewalls of the refrigerated compartment 2 along its length. When not in use, each unloading component 3 can be stored close to the inner sidewall of the refrigerated compartment 2 to avoid occupying storage space. When in use, multiple components can be unfolded according to the position of the goods to form a cargo transport support surface. An inner limit component 5 is installed on the inner sidewall of the refrigerated compartment 2 at the position corresponding to each unloading component 3 to restrict the storage state of the unloading component 3 and prevent accidental flipping of the unloading component 3.

[0026] An external unloading assembly 4 is installed on the bottom wall of the refrigerated compartment 2 near the door. It can be flipped around the connection point to the outside of the refrigerated compartment 2. After flipping, it can form an inclined support track, connecting the inside and outside of the refrigerated compartment 2 to facilitate the removal of goods. An external limiting assembly 6 is installed on the upper inner side of the refrigerated compartment 2 near the door to restrict the position of the external unloading assembly 4.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown: The unloading assembly 3 inside the box includes a frame 31 with a rectangular frame structure. Multiple first rollers 32 for reducing the sliding friction of goods are evenly rotatably connected to the inner side of the frame 31. Two connecting plates 34 for rotatable connection are symmetrically fixedly installed on one side of the frame 31. On the inner side wall of the refrigerated compartment 2, a connecting seat 33 is fixedly connected to the position corresponding to the connecting plate 34. The connecting seat 33 and the connecting plate 34 are rotatably connected by a pin, so that the frame 31 can be flipped around the pin to achieve storage or unfolding.

[0028] like Figure 6 As shown: The internal limiting assembly 5 includes a mounting base 51 that is detachably mounted on the inner wall of the refrigerated compartment 2 by bolts. A limiting baffle 52 is rotatably connected to the mounting base 51. A folded edge 35 is formed on the side of the frame 31 away from the connecting plate 34. The thickness of the folded edge 35 is adapted to the gap between the limiting baffle 52 and the inner wall of the refrigerated compartment 2. When the frame 31 is in the retracted state, the folded edge 35 is exactly located between the limiting baffle 52 and the inner wall of the refrigerated compartment 2, thereby restricting the position of the frame 31. At the same time, through holes for bolt connection are also provided on the folded edge 35 and the limiting baffle 52, and the position of the frame 31 is further fixed by bolts.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown: The external unloading assembly 4 includes two support plates 41, which are located on the bottom wall of the refrigerated compartment 2 near the door. Multiple second rollers 42, used to assist in the sliding of goods, are evenly rotatably connected between the two support plates 41 along their length.

[0030] like Figure 6 As shown: The support plate 41 includes a long plate 411 and a short plate 412. One end of the short plate 412 is rotatably connected to the inner bottom wall of the refrigerated compartment 2 near the door via a pin or a pivot. The short plate 412 and the long plate 411 are integrally formed. When the unloading assembly 4 is flipped to the outside of the refrigerated compartment 2, the short plate 412 fits against the inner bottom wall of the refrigerated compartment 2, forming an inclined cargo conveying track.

[0031] like Figure 4 and Figure 7As shown: The external limiting assembly 6 includes a threaded cylinder 61 on the upper part of the inner wall of the refrigerated compartment 2 and a threaded rod 62 adapted to the internal thread of the threaded cylinder 61. A circular through hole adapted to the diameter of the threaded rod 62 is provided on the long plate 411. When the external unloading assembly 4 is retracted, the support plate 41 is in a vertical state, the through hole is coaxially aligned with the threaded cylinder 61, and the threaded rod 62 passes through the through hole and is threadedly connected to the threaded cylinder 61, thus fixing the support plate 41.

[0032] Working principle: Before unloading, the unloading assembly 3 inside the box is unfolded. In the initial state, the unloading assembly 3 is stowed against the inner wall of the refrigerated compartment 2, and the limiting assembly 5 inside the box is fixed to it. A gap is formed between the limiting baffle 52 on the mounting base 51 and the inner wall of the refrigerated compartment 2. The folded edge 35 of the frame 31 is located in this gap, and the two are further locked by bolts to prevent accidental tipping. When unloading is required, first remove the fixing bolts between the folded edge 35 and the limiting baffle 52, and then rotate the limiting baffle 52 around the mounting base 51 to release the restriction on the folded edge 35. Then, the frame 31 is laid down, allowing it to flip around the rotation point of the connecting base 33 and the connecting plate 34 until the frame 31 is in a horizontal state, adhering to the inner bottom wall of the refrigerated compartment 2. At this time, the first roller shaft 32 on the inner side of the frame 31 forms a horizontal conveying support surface, providing a basis for the sliding of goods.

[0033] The external unloading assembly 4 is then deployed and initially stored inside the refrigerated compartment 2. The external limiting assembly 6 secures it. A threaded rod 62 passes through the through-hole of the long plate 411 and is threadedly connected to the threaded cylinder 61 above the inner wall of the refrigerated compartment 2, fixing the support plate 41 in a vertical position. During deployment, the threaded rod 62 is unscrewed, causing the support plate 41 to rotate around the rotation point of the short plate 412 and the inner bottom wall of the refrigerated compartment 2. At this time, the second roller 42 between the two support plates 41 forms an inclined conveying track.

[0034] The number of unloading components 3 that can be folded down can be freely selected according to the position of the goods inside the refrigerated compartment 2. When the goods are full and close to the door, the unloading components 3 do not need to be folded down, and the goods can be unloaded by using the unloading components 4 outside the compartment. When there are few goods and they are all inside the refrigerated compartment 2, 2-3 unloading components 3 can be folded down, so that the goods can be quickly moved to the door through multiple unloading components 3, saving the manual process of repeatedly going back and forth between the inside and outside of the compartment and saving the labor of workers.

[0035] During unloading, the goods inside the refrigerated compartment 2 are placed on the unloading assembly 3 inside the compartment. The bottom of the goods contacts the first roller 32, which rotates synchronously with the goods, greatly reducing the sliding friction of the goods. After the goods slide along the first roller 32 to the door of the refrigerated compartment 2, they pass through the inclined track of the unloading assembly 4 outside the compartment and contact the second roller 42. Under the action of gravity and with the assistance of the rotation of the second roller 42, the goods slide along the inclined track to the ground, completing the unloading operation.

[0036] After unloading, first flip the support plate 41 upwards so that the through hole of the long plate 411 is coaxially aligned with the threaded cylinder 61. Then, thread the threaded rod 62 through the through hole and screw it into the threaded cylinder 61 to fix the unloading assembly 4 outside the box. Then, flip the frame 31 in the opposite direction so that it fits the inner wall of the refrigerated compartment 2 again, so that the folded edge 35 is once again in the gap between the limiting baffle 52 and the inner wall. Rotate the limiting baffle 52 to limit it. Finally, tighten the fixing bolts to complete the storage of the unloading assembly 3 inside the box, so as to avoid occupying the internal storage space of the refrigerated compartment 2.
