Description

Technical Field

[0001] This utility model belongs to the field of logistics vehicles, and in particular relates to a cold chain logistics vehicle. Background Technology

[0002] With increasing societal demands for food safety and pharmaceutical quality, the cold chain logistics industry has developed rapidly. To facilitate the transportation of frozen or fresh goods, refrigerated logistics vehicles are typically used. These vehicles provide appropriate temperature and humidity conditions during transport, effectively extending the shelf life of food while inhibiting bacterial growth and ensuring food safety and hygiene.

[0003] Currently, loading and unloading of cold chain logistics vehicles typically relies on loading and unloading platforms or ramps on the ground. Loading and unloading platforms can be aligned with the height of the refrigerated truck's compartment, allowing goods to be directly loaded or unloaded using forklifts or lift trucks. However, this method is only suitable for large quantities of goods. For smaller goods or situations requiring delicate handling, manual loading and unloading remains the common practice. In this case, workers use handcarts, manual forklifts, and other equipment to move goods to the compartment door and then individually move them into or remove them from the compartment. However, due to the single-pass design of traditional cold chain logistics vehicles, workers can only enter and exit through the compartment door to load and unload goods. This not only reduces loading and unloading efficiency but also increases manpower consumption. Maintaining the low temperature of goods is crucial for cold chain logistics vehicles; therefore, a cold chain logistics vehicle with efficient and rapid loading and unloading capabilities is needed to prevent cold chain disruptions. Utility Model Content

[0004] The purpose of this invention is to provide a cold chain logistics vehicle that can improve loading and unloading efficiency and ensure the low temperature of goods.

[0005] The cold chain logistics vehicle includes a vehicle body and a cargo compartment. A loading plate is horizontally installed at the lower end of the cargo compartment. Sliding rails with a square frame structure are fixed to the left and right bottom of the cargo compartment. Several mounting blocks are provided in the two sliding rails and slide back and forth with them. The top of each sliding rail has a through groove that is open from top to bottom and has no front side wall. The upper end of all mounting blocks extends out of the through groove and is fixed to the bottom of the loading plate. Sliding wheels for reducing friction are installed on the left and right side walls of the lower end of all mounting blocks. The sliding wheels are in contact with the inner top and inner bottom of the sliding rails. A support component that can swing freely and is used to support the loading plate sliding out of the cargo compartment is installed at the bottom of the loading plate.

[0006] Furthermore, the top of the loading plate is provided with two vertically connected and parallel fixing grooves. Each fixing groove contains a groove body with its opening facing upwards. A lead screw and a guide rod are respectively installed in the two grooves. A slider with a threaded engagement is fitted on the lead screw, and a slider with a sliding engagement is also fitted on the guide rod. A baffle is provided above the loading plate, and both sliders are detachably connected to the lower end of the baffle through a mounting plate.

[0007] Furthermore, the mounting plate has an "L" shaped structure and its thickness is less than that of the baffle.

[0008] Furthermore, one end of the lead screw extends through the front sidewall of the corresponding groove and is fixed with a prismatic connector rod.

[0009] Furthermore, the carriage is equipped with a door for sealing the carriage.

[0010] Furthermore, when the loading plate moves backward to the point where it can no longer move, the front side wall of the loading plate is in contact with the closed carriage.

[0011] Furthermore, the loading plate is in the form of a grid.

[0012] Furthermore, a handle is fixed to the front top of the loading plate.

[0013] Furthermore, the support assembly includes a support rod, one end of which is equipped with a roller, and the other end is hinged to a hinge seat. The hinge seat is fixed to the bottom of the loading plate, and the support rod can be locked in a vertical state by a limiter.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention utilizes two sliding tracks and several mounting blocks that slide back and forth with the sliding tracks, with one end fixed to the bottom of the loading plate and the other end equipped with sliding wheels. This allows the loading plate to move only along the sliding tracks, enabling workers to easily and freely drive the loading plate into and out of the truck bed. Since the loading plate extends out of the truck bed and is no longer restricted by the truck bed, workers can load and unload goods from multiple directions simultaneously. Compared to unloading goods from a truck bed with only one passageway, this invention significantly improves the efficiency of loading and unloading goods, ensures the low temperature of the goods, and prevents cold chain breakage.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0022] Example 1

[0023] The cold chain logistics vehicle described in this embodiment includes a vehicle body 6 and a cargo compartment 1, such as... Figure 1 As shown, the carriage 1 is equipped with a door 12 for sealing the carriage 1. The vehicle body 6 can be a fuel vehicle or a new energy vehicle. The refrigeration of the carriage 1 can be independent, that is, equipped with a separate diesel engine to drive the compressor, which is not affected by the vehicle engine and is suitable for long-distance transportation. It can also be non-independent, that is, it relies on the vehicle engine power, which is low in cost but cannot refrigerate when parked.

[0024] A loading plate 4 is horizontally installed at the lower end of the carriage 1. In this embodiment, the cargo is placed on the loading plate 4 instead of being placed directly at the bottom of the carriage 1 (in practice, a wooden pallet is also placed underneath). The loading plate 4 is grid-shaped, which can ensure that cold air can circulate in the carriage 1 (the cold air in some models is generated from the bottom) and reduce the manufacturing cost of the loading plate 4 while ensuring the load-bearing capacity.

[0025] refer to Figure 1 , Figure 2 and Figure 3The bottom left and bottom right of the carriage 1 are both fixed with sliding rails 10 in the shape of square frames. Each sliding rail 10 has several mounting blocks 15 that slide back and forth with it. The top of each sliding rail 10 has a through groove that is vertically connected and has no front sidewall. The upper ends of all mounting blocks 15 extend through the through grooves and are fixed to the bottom of the loading plate 4. In this embodiment, the two sliding rails 10 and the several mounting blocks 15 that slide back and forth with the sliding rails 10 and are fixed to the bottom of the loading plate 4 allow the loading plate 4 to move along the sliding rails 10, thus enabling the worker to drive the loading plate 4 freely. Once the loading plate 4 extends out of the carriage 1, it is no longer restricted by the carriage 1. Workers can load and unload goods from multiple directions simultaneously. Compared to unloading goods from a carriage 1 with only one passage, this embodiment can significantly improve the efficiency of loading and unloading goods, ensure the low temperature of goods, and avoid cold chain breakage. At the same time, because the loading and unloading space is larger, more workers can participate in loading and unloading, thus reducing the manpower consumption of a single worker. Among them, the top front of the loading plate 4 is fixed with a handle 7, which makes it more convenient and less strenuous for workers to pull the loading plate 4.

[0026] In practical applications, when the loading plate 4 moves backward to the point where it can no longer move, the front side wall of the loading plate 4 is in contact with the closed compartment 1, thereby preventing the loading plate 4 from shaking during vehicle operation.

[0027] refer to Figure 1 , Figure 2 and Figure 3 All mounting blocks 15 have sliding wheels 14 installed on their lower left and right sidewalls to reduce friction. The sliding wheels 14 are in contact with the inner top and bottom of the sliding track 10. In this embodiment, the sliding wheels 14 not only reduce friction when the mounting blocks 15 slide, allowing workers to easily push the loading plate 4 in and out of the carriage 1, but also prevent the mounting blocks 15 from detaching from the sliding track 10 upwards when the loading plate 4 is under load, thus ensuring the stability of the mounting blocks 15. Figure 2 As shown, the mounting block 15 has an inverted "T" shaped structure. The left and right walls at both ends of the mounting block 15 are equipped with sliding wheels 14, which can further improve the load-bearing capacity and stability of the loading plate 4.

[0028] A support assembly 5, which can swing freely and is used to support the loading plate 4 as it slides out of the carriage 1, is installed at the bottom of the loading plate 4. In this embodiment, the swingable support assembly 5 can support the loading plate 4 as it swings out of the carriage 1. Figure 2 In the vertical position shown, the portion of the loading plate 4 extending out of the carriage 1 is supported to prevent the loading plate 4 from bending due to excessive force, thereby increasing the maximum load-bearing capacity of the loading plate 4. Simultaneously, the support assembly 5 can be swung to... Figure 1In the horizontal position shown, the support assembly 5 is completely retracted between the loading plate 4 and the inner bottom of the carriage 1, thus eliminating the need to find additional supports when the loading plate 4 needs support, thereby improving the efficiency of loading and unloading goods to some extent; Figure 1 and Figure 2 As shown, the support assembly 5 includes a support rod 5.1. One end of the support rod 5.1 is equipped with a roller 5.2, and the other end is hinged to a hinge seat 5.3. The hinge seat 5.3 is fixed to the bottom of the loading plate 4. The support rod 5.1 can be locked in a vertical position by a limiter, which can be a bolt or a positioning pin. The hinge seat 5.3 has an "n" shaped structure. The front side wall of the hinge seat 5.3 has a through hole. The front side wall of the support rod 5.1 has threaded holes that are concentric with the through hole when in a vertical position. Therefore, when the support rod 5.1 is swung to a vertical position, the bolt or positioning pin can be inserted into the through hole and the threaded hole in sequence to quickly lock the position of the support rod 5.1, preventing the support rod 5.1 from swaying as the loading plate 4 slides.

[0029] In this embodiment, the loading plate 4 is first pulled out of the carriage 1. When loading, it is pulled out completely and then pushed back into the carriage 1 little by little. When unloading, it is pulled out little by little. Then the support rod 5.1 is swung downward to a vertical position and fixed. Then the worker can load the goods onto the loading plate 4 or unload them from the loading plate 4.

[0030] Example 2

[0031] This embodiment further explains the technology. The top of the loading plate 4 has two parallel, vertically connected fixing grooves. Each groove contains an upward-facing groove body 3. A lead screw 9 and a guide rod are respectively installed in each groove body 3. A slider 8 with a threaded engagement is fitted onto the lead screw 9, and a slider 8 with a sliding engagement is also fitted onto the guide rod. A baffle 2 is provided above the loading plate 4. Both sliders 8 are detachably connected to the lower end of the baffle 2 via a mounting plate 11. In this embodiment, the drive of the lead screw 9 and the limiting position of the guide rod can drive the baffle 2 to move back and forth, thus holding the goods in place after loading and preventing them from slipping during vehicle movement, especially when the cargo compartment 1 is not full. Furthermore, since the baffle 2 is detachable, it will not obstruct the loading and unloading process. Figure 1 , Figure 2 and Figure 4 As shown, the mounting plate 11 and the baffle 2 are connected by bolts. The mounting plate 11 has an "L" shape and its thickness is less than that of the baffle 2, so as to ensure that the mounting plate 11 can contact the goods. The two ends of the lead screw 9 and the guide rod are installed in the groove 3 through bearings. The front end of the lead screw 9 passes through the front side wall of the corresponding groove 3 and is fixed with a prismatic plug rod 13. Through the prismatic plug rod 13, the worker can temporarily connect a rotating handle to rotate the lead screw 9 with less effort.
