Description

Technical Field

[0001] This application relates to the field of logistics vehicles, and more specifically, to a logistics vehicle with an extended structure. Background Technology

[0002] In today's booming modern logistics industry, efficiency and cost control in logistics transportation have become key factors in corporate competitiveness. As the core carrier of cargo transportation, the loading capacity and applicability of logistics vehicles directly affect the efficiency of logistics operations.

[0003] However, most common logistics vehicles on the market use fixed-size body structures, and their cargo loading space is determined at the factory, making it impossible to flexibly adjust according to the actual scale of the transported goods. When encountering situations where the quantity of goods is large, the volume is large, or bulk transportation is required, fixed-body logistics vehicles often need to make multiple round trips due to limited loading space. This not only increases transportation costs but also significantly reduces the efficiency of logistics transportation. Furthermore, stacking is subject to height restrictions. Therefore, this application proposes a logistics vehicle with an extended structure. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of existing technologies by providing a logistics vehicle with an extendable structure, thereby solving the problem that the fixed body structure of existing logistics vehicles makes it difficult to flexibly adjust according to the actual scale of transported goods.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A logistics vehicle with an extended structure includes a logistics vehicle body, on which a box girder is provided along its length, and a cargo box is mounted on the box girder. An extension beam arm is movably passed through one end of the box girder facing the rear of the logistics vehicle body. A pair of extension beam arms are arranged side by side, and one end of the pair of extension beam arms extending out of the box girder is connected to an extension bridge arm. A hydraulic push rod is also installed at the end of the box girder facing the rear of the logistics vehicle body, and the telescopic end of the hydraulic push rod extends out of the box girder and connects to the extension bridge arm.

[0008] Furthermore, the cargo compartments are provided in multiple ways, and the multiple cargo compartments are distributed along the length of the logistics vehicle body.

[0009] Furthermore, the box girder is equipped with a frame bridge arm, which is distributed along the width direction of the logistics vehicle body, and multiple frame bridge arms are arranged along the length direction of the logistics vehicle body, with the frame bridge arms and the extended bridge arms horizontally aligned.

[0010] Furthermore, the two ends of the frame bridge arm located at the rear of the logistics vehicle body are horizontally movably fitted with extension plates. A pair of extension plates are distributed side by side on both sides of a pair of extension beam arms, and the pair of extension plates are fixedly connected to the extension bridge arm.

[0011] Furthermore, the extension length of the extension beam arm, extension plate, and hydraulic push rod is greater than the length of the cargo box.

[0012] Furthermore, a hanger is provided at the bottom of the extended bridge arm, and a taillight is provided on the hanger.

[0013] Furthermore, multiple sets of guardrails are provided on the upper surfaces of each pair of extension plates on opposite sides, and the guardrails can be rotated and horizontally retracted toward the side of the extension beam arm.

[0014] Furthermore, the guardrail includes a lower strip, an upper strip disposed above the lower strip, and multiple vertical bars vertically connected between the lower strip and the upper strip. A boss is fixed on the upper surface of a pair of extension plates on opposite sides. An assembly groove is provided on the boss. A connecting shaft is fixed at the bottom of the lower strip. The connecting shaft is rotatably fitted into the assembly groove. The lower strip, the upper strip, and the vertical bars can rotate toward the extension beam arm side and fit against the extension plate through the connecting shaft. A positioning bolt is threaded through the vertical thread of the lower strip. The positioning bolt is inserted into the vertical thread of the boss.

[0015] The beneficial effects of this application are as follows:

[0016] By setting up extension beams, extension plates, and hydraulic push rods, the rear of the logistics vehicle body can be extended, increasing the cargo loading capacity of the logistics vehicle, meeting the transportation needs of goods of different sizes, and improving the efficiency of logistics transportation.

[0017] The guardrails effectively protect loose cargo loaded onto the logistics vehicle when it is extended, preventing goods from falling off due to shaking during transportation. Furthermore, the guardrails can be rotated and folded, reducing space usage when not in use and facilitating the operation and parking of the logistics vehicle. Attached Figure Description

Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0029] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0030] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Reference Figure 1-4 As shown, this utility model provides a logistics vehicle with an extended structure, including a logistics vehicle body 1, a box beam 2, cargo boxes 3, an extension beam arm 4, an extension plate 5, a frame bridge arm 6, an extension bridge arm 7, a hydraulic push rod 8, and a guardrail 10. The logistics vehicle body 1 is equipped with a box beam 2 along its length, and multiple cargo boxes 3 are mounted on the box beam 2. The multiple cargo boxes 3 are evenly distributed along the length of the logistics vehicle body 1 for storing goods.

[0032] Furthermore, in this embodiment, an extension beam arm 4 is movably inserted through one end of the box girder 2 facing the rear of the logistics vehicle body 1, and a pair of extension beam arms 4 are arranged side by side. One end of each pair of extension beam arms 4 extending outside the box girder 2 is connected to an extension bridge arm 7. A hydraulic push rod 8 is also installed at the end of the box girder 2 facing the rear of the logistics vehicle body 1, with its telescopic end extending outside the box girder 2 and connected to the extension bridge arm 7. Through the telescopic movement of the hydraulic push rod 8, the extension bridge arm 7 and the extension beam arm 4 can be driven to telescopically move, thereby realizing the extension function of the rear of the logistics vehicle body 1.

[0033] Furthermore, in this embodiment, a frame axle arm 6 is also mounted on the box girder 2. The frame axle arm 6 is distributed along the width direction of the logistics vehicle body 1, and multiple frame axle arms 6 are arranged along the length direction of the logistics vehicle body 1. The frame axle arm 6 is horizontally aligned with the extension axle arm 7, providing support for the assembly of the cargo box 3. Extension plates 5 are horizontally movable at both ends of the frame axle arm 6 located at the rear of the logistics vehicle body 1. A pair of extension plates 5 are distributed side by side on both sides of a pair of extension beam arms 4, and the pair of extension plates 5 are fixedly connected to the extension axle arm 7. When the extension beam arm 4 extends or retracts, the extension plates 5 move synchronously, expanding the loading space of the logistics vehicle. In order to ensure that the extension length of the extension beam arm 4, extension plates 5, and hydraulic push rod 8 can meet the actual needs, the extension length of the extension beam arm 4, extension plates 5, and hydraulic push rod 8 is greater than the length of the cargo box 3, so as to ensure that the logistics vehicle can load more goods in the extended state.

[0034] In this embodiment, a hanger 11 is provided at the bottom of the extended bridge arm 7, and a taillight 12 is provided on the hanger 11. The taillight 12 is used to provide warning signals during the operation of the logistics vehicle to ensure driving safety.

[0035] Furthermore, in this embodiment, multiple sets of guardrails 10 are provided on the upper surfaces of the pair of extension plates 5 on the opposite sides. Each guardrail 10 includes a lower strip 13, an upper strip 14 positioned above the lower strip 13, and multiple vertical bars 15 connecting the lower strip 13 and the upper strip 14. A boss 9 is fixed to the upper surface of the pair of extension plates 5 on the opposite sides, and an assembly groove 16 is provided on the boss 9. A connecting shaft 17 is fixed to the bottom of the lower strip 13, and the connecting shaft 17 is rotatably fitted into the assembly groove 16. Through the connecting shaft 17, the guardrail 10 can rotate horizontally and retract towards the side of the extension beam arm 4. When the guardrail 10 rotates and retracts towards the extension beam arm 4, it can retract towards the side of the box girder 2 along with the extension beam arm 4, reducing the space occupied. When the guardrail 10 is rotated to the upright position, a positioning bolt 18 is threaded through the vertical thread on the lower strip 13. The positioning bolt 18 is engaged with the vertical thread of the boss 9 to vertically position the guardrail 10 and prevent the guardrail 10 from shaking during use.

[0036] Working principle: When the loading space of this logistics vehicle with an extended structure needs to be expanded, the hydraulic push rod 8 is activated. The telescopic end of the hydraulic push rod 8 extends outward, pushing the extension bridge arm 7 to move outward. Since the extension bridge arm 7 is connected to the extension beam arm 4, the extension beam arm 4 will slide outward in the box girder 2. Meanwhile, because the extension plate 5 is fixedly connected to the extension bridge arm 7, the extension plate 5 will also extend outward as the extension bridge arm 7 and the extension beam arm 4 move, thereby expanding the cargo space. When the extended extension bridge arm 7 and the extension beam arm 4 are used to load the cargo box 3, the guardrail 10 is in the retracted state. The extension bridge arm 7 and the frame bridge arm 6 provide a loading platform for the cargo box 3. When loading bulk cargo, the guardrail 10 can be rotated around the connecting shaft 17 to the upright state, and then the positioning bolt 18 is rotated vertically downward to make it threaded into the threaded hole (not shown in the figure) on the boss 9, thereby fixing the guardrail 10 in the upright position. At the same time, wooden boards or iron sheets are laid on the extension bridge arm 7, the extension beam arm 4 and the extension plate 5 to load bulk cargo in the cargo box. The guardrail 10 can prevent the cargo from falling off during transportation.

[0037] When the transportation task is completed and the logistics vehicle needs to be restored to its initial state, the hydraulic push rod 8 is activated again, causing its telescopic end to retract inward, which in turn drives the extension bridge arm 7, extension beam arm 4, and extension plate 5 to retract inward. At the same time, the guardrail 10 is rotated horizontally around the connecting shaft 17 toward the extension beam arm 4, so that it retracts along with the extension beam arm 4 through the frame bridge arm 6 and back to both sides of the box girder 2, reducing the overall space occupied by the logistics vehicle.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
