Description

Technical Field

[0001] This utility model belongs to the field of logistics vehicle technology, and in particular relates to a logistics vehicle with an anti-collision structure. Background Technology

[0002] Logistics vehicles are unit-type mobile containerized equipment equipped with four casters for transporting and storing materials. They are commonly used in the logistics distribution of large supermarkets or the logistics turnover between processes in factories. During the transportation of goods, logistics vehicles are frequently subject to collisions, sudden braking, or instantaneous acceleration that can cause damage to the goods. This is especially true for fragile or explosive goods, such as ceramic products, high-precision instruments, and natural gas cylinders; even a slight collision can render the goods unusable or create a dangerous situation.

[0003] For example, patent CN210235071U discloses a collision-resistant logistics vehicle, including: a logistics vehicle floor, a logistics vehicle middle plate, a logistics vehicle upper pressure plate, and a logistics vehicle cover. The top of the logistics vehicle floor has a floor spring receiving groove and a cargo receiving groove; the bottom of the logistics vehicle middle plate has a middle plate spring lower receiving groove, both containing springs; the top of the logistics vehicle middle plate has a middle plate spring upper receiving groove and a cargo receiving groove; and the bottom of the logistics vehicle upper pressure plate has an upper pressure plate spring receiving groove and a cargo receiving groove, both containing springs. When the logistics vehicle collides or brakes suddenly, due to the spring action, the logistics vehicle middle plate and floor shift, as do the logistics vehicle upper pressure plate and middle plate, thus achieving a certain buffering effect, significantly improving transportation efficiency, and preventing damage to goods caused by collisions.

[0004] Existing logistics vehicles with anti-collision structures cannot protect against collisions from different directions, resulting in low anti-collision performance. Therefore, we propose a logistics vehicle with an anti-collision structure. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a logistics vehicle with a collision protection structure, thereby avoiding the problem of low collision protection performance of logistics vehicles due to the inability to protect against collisions from different directions.

[0006] In view of this, the present invention provides a logistics vehicle with an anti-collision structure, including a frame, with rollers installed at the four corners of the bottom edge of the frame, a push handle fixedly connected to the side wall of the frame, and columns fixedly connected to the four corners of the top edge of the frame. A fixed frame is fixedly connected to the outer wall of the column, and a buffer frame is fixedly connected to the outer wall of the column. A telescopic connecting plate is slidably connected to the inner wall of the buffer frame. A connecting rod is screwed to both ends of the telescopic connecting plate. A telescopic block is screwed to one end of the connecting rod and slidably connected to the inner wall of the buffer frame. A damping spring is fixedly connected to the connection part of the telescopic block and the buffer frame. A limit plate is slidably connected to the outer wall of the telescopic connecting plate. A protective plate is fixedly connected to the outer wall of the limit plate. A buffer pad is installed at the connection part of the protective plate and the column.

[0007] Based on the above structure, when the frame collides during transport, the protective plate initially cushions the uprights with a buffer pad. Then, the collision of the protective plate causes the telescopic connecting plate to slide horizontally along the inner wall of the buffer frame. At the same time, the movement of the telescopic connecting plate causes two sets of connecting rods to move synchronously, so that the movement of the telescopic connecting plate causes the telescopic block to slide vertically and horizontally along the buffer frame through the connecting rods. The telescopic block causes the damping spring to be compressed, which facilitates the conversion of the kinetic energy generated by the collision of the protective plate into the internal energy of the damping spring, thereby realizing the buffering operation of the protective plate. By setting a limit plate, it is beneficial to provide comprehensive protection against collisions from different directions of the protective plate.

[0008] Preferably, the outer wall of the fixed frame is mesh-like, and the cross-section of the column is square. In this embodiment, by setting a fixed frame with a mesh-like outer wall, it is beneficial to reduce the overall weight of the logistics vehicle and make it easier for staff to push the logistics vehicle smoothly.

[0009] Preferably, the buffer frame is provided in two sets, and the two sets of buffer frames are perpendicular to each other. In this embodiment, by providing two sets of buffer frames, it is beneficial to provide comprehensive protection against collisions from different directions of the protective plate.

[0010] Preferably, the protective plate has an "L" shaped cross-section. In this embodiment, by setting an "L" shaped protective plate, the column can be fully protected.

[0011] Preferably, a screw is screwed onto the inner wall of the frame, and a toothed plate is threaded onto the outer wall of the screw. A gear meshes with the meshing surface of the toothed plate. A coupling screwed onto the outer wall of the gear is fixedly connected to the outer wall of the frame. Both ends of the coupling are fixedly connected to driving plates. A driven plate is screwed onto the top of the driving plate. A lifting plate is screwed onto the top of the driven plate. A lifting frame slidably connected to the outer wall of the column is fixedly connected to the top of the lifting plate. In this embodiment, the rotation of the screw drives the coupling to rotate through the meshing of the toothed plate and the gear. The rotation of the coupling drives the two sets of driving plates to rotate synchronously. The rotation of the driving plate drives the lifting frame at the top of the lifting plate to slide vertically along the outer wall of the column through the driven plate, thereby realizing the lifting operation of the lifting frame, which is beneficial to improving the storage capacity of the logistics vehicle.

[0012] Preferably, the active plate and the driven plate are of equal length. In this embodiment, the rotation of the active plate drives the lifting frame at the top of the lifting plate to slide vertically along the outer wall of the column through the driven plate, thereby realizing the lifting operation of the lifting frame.

[0013] Preferably, the outer wall of the lifting frame is in contact with the inner wall of the fixed frame, and the outer wall of the lifting frame is mesh-like. In this embodiment, it is convenient for the lifting plate to slide and drive the lifting frame and the fixed frame to move relative to each other, so as to avoid deformation of the fixed frame and the lifting frame after long-term use.

[0014] The beneficial effects of this utility model are:

[0015] 1. This logistics vehicle with an anti-collision structure is equipped with an active plate and a driven plate. The rotation of the screw drives the coupling to rotate through the meshing of the toothed plate and gear. The rotation of the coupling drives the two sets of active plates to rotate synchronously. The rotation of the active plate drives the lifting frame at the top of the lifting plate to slide vertically along the outer wall of the column through the driven plate, thereby realizing the lifting operation of the lifting frame, which is conducive to improving the storage capacity of the logistics vehicle.

[0016] 2. This logistics vehicle with a collision protection structure, by setting up buffer pads and protective plates, allows the protective plates to initially cushion the uprights when the frame collides during transport. Then, the collision of the protective plates causes the telescopic connecting plate to slide horizontally along the inner wall of the buffer frame. At the same time, the movement of the telescopic connecting plate causes two sets of connecting rods to move synchronously, so that the movement of the telescopic connecting plate causes the telescopic block to slide vertically and horizontally along the buffer frame through the connecting rods. The telescopic block causes the damping spring to be compressed, which facilitates the conversion of the kinetic energy generated by the collision of the protective plate into the internal energy of the damping spring, thus realizing the buffering operation of the protective plate. By setting up a limit plate, it is beneficial to provide comprehensive protection against collisions of the protective plate from different directions. Attached Figure Description

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0024] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0025] This application discloses a logistics vehicle with an anti-collision structure, including a frame 1. Rollers 2 are installed at the four corners of the bottom edge of the frame 1. A push handle 3 is fixedly connected to the side wall of the frame 1. A column 4 is fixedly connected to the four corners of the top edge of the frame 1. A fixed frame 5 is fixedly connected to the outer wall of the column 4. A buffer frame 6 is fixedly connected to the outer wall of the column 4. A telescopic connecting plate 7 is slidably connected to the inner wall of the buffer frame 6. A connecting rod 8 is screwed to both ends of the telescopic connecting plate 7. A telescopic block 9 is screwed to one end of the connecting rod 8 and slidably connected to the inner wall of the buffer frame 6. A damping spring 10 is fixedly connected to the connection part between the telescopic block 9 and the buffer frame 6. A limit plate 11 is slidably connected to the outer wall of the telescopic connecting plate 7. A protective plate 12 is fixedly connected to the outer wall of the limit plate 11. A buffer pad 13 is installed at the connection part between the protective plate 12 and the column 4.

[0026] Based on the above structure, when the frame 1 collides during transport, the protective plate 12 initially cushions the column 4 through the buffer pad 13. Then, the collision of the protective plate 12 causes the telescopic connecting plate 7 to slide horizontally along the inner wall of the buffer frame 6. At the same time, the movement of the telescopic connecting plate 7 causes the two sets of connecting rods 8 to move synchronously, so that the movement of the telescopic connecting plate 7 causes the telescopic block 9 to slide vertically and horizontally along the buffer frame 6 through the connecting rods 8. The telescopic block 9 causes the damping spring 10 to be compressed, which facilitates the conversion of the kinetic energy generated by the collision of the protective plate 12 into the internal energy of the damping spring 10, thereby realizing the buffering operation of the protective plate 12. By setting the limiting plate 11, it is beneficial to provide comprehensive protection against collisions of the protective plate 12 from different directions.

[0027] In one embodiment, the outer wall of the fixed frame 5 is mesh-like, and the cross-section of the column 4 is square.

[0028] In this embodiment, by setting a fixed frame 5 with a mesh outer wall, it is beneficial to reduce the overall weight of the logistics vehicle and make it easier for staff to push the logistics vehicle smoothly.

[0029] In one embodiment, the buffer frame 6 is provided in two sets, and the two sets of buffer frames 6 are perpendicular to each other.

[0030] In this embodiment, by setting two sets of buffer frames 6, it is beneficial to provide comprehensive protection against collisions from different directions of the protective plate 12.

[0031] In one embodiment, the protective plate 12 has an "L" shaped cross-section.

[0032] In this embodiment, a protective plate 12 with an "L"-shaped cross-section is provided to achieve full protection of the column 4.

[0033] In one embodiment, a screw 14 is screwed onto the inner wall of the frame 1, and a toothed plate 15 is threaded onto the outer wall of the screw 14. A gear 16 meshes with the meshing surface of the toothed plate 15. A coupling 17, which is screwed onto the outer wall of the gear 16, is fixedly connected to the outer wall of the frame 1. Both ends of the coupling 17 are fixedly connected to a drive plate 18. A driven plate 19 is screwed onto the top of the drive plate 18. A lifting plate 20 is screwed onto the top of the driven plate 19. A lifting frame 21, which is slidably connected to the outer wall of the column 4, is fixedly connected to the top of the lifting plate 20.

[0034] In this embodiment, the rotation of the screw 14 drives the coupling 17 to rotate through the meshing of the toothed plate 15 and the gear 16. The rotation of the coupling 17 drives the two sets of active plates 18 to rotate synchronously. The rotation of the active plates 18 drives the lifting frame 21 at the top of the lifting plate 20 to slide vertically along the outer wall of the column 4 through the driven plate 19, thereby realizing the lifting operation of the lifting frame 21, which is beneficial to improving the storage capacity of the logistics vehicle.

[0035] In one embodiment, the active plate 18 and the driven plate 19 are of equal length.

[0036] In this embodiment, the rotation of the active plate 18 drives the lifting frame 21 at the top of the lifting plate 20 to slide vertically along the outer wall of the column 4 via the driven plate 19, thereby achieving the lifting operation of the lifting frame 21.

[0037] In one embodiment, the outer wall of the lifting frame 21 is attached to the inner wall of the fixed frame 5, and the outer wall of the lifting frame 21 is mesh-like.

[0038] In this embodiment, the lifting plate 20 is slidably driven to move the lifting frame 21 relative to the fixed frame 5, thus avoiding deformation of the fixed frame 5 and the lifting frame 21 after long-term use.

[0039] In this embodiment, the logistics vehicle with anti-collision structure is used by first raising the lifting frame 21. The operator rotates the screw 14, which drives the coupling 17 to rotate through the meshing of the toothed plate 15 and the gear 16. The rotation of the coupling 17 drives the two sets of active plates 18 to rotate synchronously. The rotation of the active plates 18 drives the lifting frame 21 at the top of the lifting plate 20 to slide vertically along the outer wall of the column 4 through the driven plate 19, thereby raising the lifting frame 21 and improving the storage capacity of the logistics vehicle.

[0040] Next, the staff put the materials into the logistics vehicle. Then, the staff pushed the handle 3, and the movement of the handle 3 transferred the frame 1 to a suitable location through the roller 2.

[0041] Finally, when the frame 1 collides during transport, the protective plate 12 initially cushions the column 4 through the buffer pad 13. Then, the collision of the protective plate 12 causes the telescopic connecting plate 7 to slide horizontally along the inner wall of the buffer frame 6. At the same time, the movement of the telescopic connecting plate 7 causes the two sets of connecting rods 8 to move synchronously, so that the movement of the telescopic connecting plate 7 causes the telescopic block 9 to slide vertically and horizontally along the buffer frame 6 through the connecting rods 8. The telescopic block 9 causes the damping spring 10 to be compressed, which facilitates the conversion of the kinetic energy generated by the collision of the protective plate 12 into the internal energy of the damping spring 10, thereby realizing the buffering operation of the protective plate 12. By setting the limit plate 11, it is beneficial to provide comprehensive protection against collisions of the protective plate 12 from different directions.
