Description

Technical Field

[0001] The invention relates to the technical field of freight vehicles, in particular to a freight vehicle. Background Art

[0002] Freight trucks, also known as trucks, are mainly used to transport goods. Depending on their purpose, load capacity and driving mode, freight trucks can be divided into many types, including light trucks, medium trucks, heavy trucks, etc.

[0003] The compartment of a freight truck is mainly formed by interconnected steel baffles, and the baffles are used to prevent the cargo from falling when the vehicle is transporting cargo. The baffles need to be opened and closed manually when loading and unloading cargo.

[0004] In order to overcome the above defects, the Chinese patent of prior art 1 (publication number: CN107499394B) discloses a car baffle assist device and a car car, which is provided with a slider, a connecting rod and an elastic member. When the car baffle is opened downward, the connecting rod converts the rotational motion of the car side wall into the linear motion of the slider, thereby compressing the elastic member and absorbing part of the potential energy of the baffle falling; and when the car baffle is closed upward, the elastic potential energy of the elastic member is released to compensate for part of the lifting force that makes the baffle rise, so as to achieve assist in the operation of the car baffle. Therefore, the present invention can provide assistance for operators to open and close the car baffle.

[0005] There is also a Chinese patent of prior art 2 (publication number: CN209176567U) that discloses an automatic opening and closing device for a dump truck compartment baffle. By controlling the extension of the piston rod of the oil cylinder, the rotating body rotates around the rotating pin shaft, and the movable compartment rear baffle is opened; conversely, when the compartment rear baffle needs to be closed, the piston rod of the oil cylinder is retracted, so that the rotating body rotates around the rotating pin shaft to achieve the closing of the compartment rear baffle. There is a clearance fit between the rotating body and the rotating pin shaft, and between the rotating body and the oil cylinder. By controlling the extension and retraction of the piston rod of the oil cylinder, the rotating body rotates 90° around the rotating pin shaft, thereby achieving the opening and closing needs of the movable baffle.

[0006] The above-mentioned prior art 1 converts the rotational motion of the side wall of the carriage into the linear motion of the slider through a connecting rod, thereby compressing the elastic part and absorbing part of the potential energy of the falling baffle, thereby realizing the assistance of the operation of the carriage baffle. Prior art 2 controls the extension and retraction of the piston rod of the oil cylinder to make the rotating body rotate 90° around the rotating pin axis, thereby realizing the opening and closing needs of the movable baffle. In actual use, the carriage baffle rotates around the axis at its bottom during movement. When the baffle moves to a state parallel to the ground, the space occupied by the baffle will reach the maximum, which is inconvenient to operate the baffle in a small space.

[0022] Furthermore, by simultaneously moving multiple drive bars, the cargo is moved in a direction away from the front panel of the carriage, thereby transporting the cargo to the end of the carriage floor away from the front panel of the carriage. Conversely, the cargo can be transported from the end of the carriage front panel away from the floor to one end of the carriage front panel in the carriage floor space, thereby reducing the physical exertion of personnel loading and unloading cargo.

[0048] Embodiment 2:

[0049] Based on the first embodiment, the specific working principle is as follows:

[0050] This kind of freight vehicle, when the vehicle is transporting goods, the vehicle will be Figure 1 In the state shown, the cargo will be located inside the compartment formed by the compartment floor 3, the compartment front panel 4, the compartment side panels 14 and the compartment rear panel 18. When the vehicle needs to load or unload cargo, the vehicle will be in a Figure 2 In the state shown, the side panels 14 and the rear panel 18 of the carriage will move to the bottom of the plane formed by the driving strip 24, so that the top of the carriage floor 3 forms an open structure, thereby facilitating the loading and unloading of goods;

[0051] When adjusting the side panel 14 of the carriage, the motor inside the vehicle body 2 is used to drive the screw rod 8 to rotate. Since the adjusting block 9 is threadedly connected to the outside of the screw rod 8, when the screw rod 8 rotates, the adjusting block 9 will move up and down on the outside of the screw rod 8. When the adjusting block 9 moves up and down on the outside of the screw rod 8, the adjusting block 9 will move the adjusting ring 10 on one side up and down, so that the adjusting ring 10 drives the end of the adjusting rod 11 to slide inside it. When the adjusting rod 11 moves with the adjusting block 9, the adjusting rod 11 will rotate around the fixed axis 5, and the adjusting rod 11 The ends slide inside the adjusting ring 10 at the same time. When the adjusting rod 11 rotates around the fixed shaft 5, the adjusting rod 11 will drive the driving rod 12 to rotate around the fixed shaft 5. When the driving rod 12 rotates around the fixed shaft 5, the end of the driving rod 12 away from the adjusting rod 11 and the fixed shaft 5 will rotate around the fixed shaft 5. The driving rod 12 drives the carriage side panels 14 to move through the connection between its ends and the adjusting shaft 15, so that the carriage side panels 14 move downward on both sides of the carriage floor 3, thereby adjusting the position of the carriage side panels 14 on the outer side of the carriage floor 3.

[0052] During the movement of the carriage side panel 14, the structural rod inside it will move with the adjustment shaft 15. Since the two fixed shafts 5 and the two carriage side panels 14, the driving rod 12 and the positioning rod 13 form a parallelogram structure, the driving rod 12 drives the carriage side panel 14 to move and always maintains a parallel state with the two fixed shafts 5. At the same time, the carriage side panel 14 will always maintain a direction perpendicular to the carriage floor 3 during the movement, so that the carriage side panel 14 will not rotate during the movement, thereby reducing the occupied area of ​​the carriage side panel 14 during the movement, so that the carriage side panel 14 can be normally adjusted in a relatively narrow position;

[0053] During the operation of the rear panel 18 of the carriage, firstly, the two second buckles 19 are separated from the second fixing ring 17, and the upper end of the rear panel 18 of the carriage will be in a free state. At this time, the mounting strip 20 at the bottom of the rear panel 18 of the carriage rotates around the rotating seat 21, so that the rear panel 18 of the carriage moves to the bottom of the plane formed by the driving strip 24, so that the rear side of the carriage is in an open state. The two side panels 14 of the carriage are controlled by the two screw rods 8, and the two side panels 14 of the carriage can be controlled independently of each other. When the side panels 14 of the carriage are installed on both sides of the top of the floor panel 3 of the carriage, the first buckle 16 and the first fixing ring 7 are connected to each other, so that the top of the side panels 14 of the carriage and the floor panel 3 are connected to each other as a whole, and each side panel 14 of the carriage and the rear panel 18 of the carriage can be connected to form a whole through the connection of the second fixing ring 17 and the second buckle 19, and the two side panels 14 of the carriage can be separated from the floor panel 3 or the rear panel 18 of the carriage separately, thereby improving the flexibility of loading and unloading goods in the carriage;

[0054] When the cargo is loaded inside the carriage, the cargo is located at the top of the plane formed by multiple equally spaced driving bars 24. At this time, the moving end 26 is driven to slide in the sliding hole 23 by the telescopic rod 27. First, multiple driving bars 24 are driven to move simultaneously, and the cargo is moved in the direction away from the carriage front plate 4 through the driving bars 24. The non-adjacent driving bars 24 are divided into two groups, and the two groups of driving bars 24 move in the direction of the space carriage front plate 4 in turn. At this time, half of the driving bars 24 at the bottom of the cargo are in motion, and half of the driving bars 24 will be in a stationary state, so that the friction forces on the bottom of the cargo in two directions are consistent. When the two groups of driving bars 24 move to fit with the installation box 22 respectively, the cargo on the top thereof will not move, and the cargo is moved in the direction away from the carriage front plate 4 through the simultaneous movement of multiple driving bars 24, thereby transporting the cargo to the end of the carriage floor 3 away from the carriage front plate 4. Conversely, the cargo can be transported from the end of the carriage front plate 4 away from the carriage floor 3 to the end of the carriage front plate 4 in the space of the carriage floor 3, thereby reducing the physical exertion of the personnel loading and unloading the cargo.
