Description

Technical Field

[0001] This utility model relates to the technical field of automobile chassis packaging boxes, specifically an automobile chassis packaging box. Background Technology

[0002] As the core load-bearing component of a car, the chassis has a complex structure and contains many precision connection parts. The quality of protection during transportation directly affects the subsequent assembly accuracy and safety of the entire vehicle.

[0003] However, it still has some drawbacks. For example, the current automotive chassis packaging boxes have a relatively simple structure during use, mostly using a single hard base plate or a small amount of foam filling for protection. They lack an effective elastic cushioning structure. When encountering bumps or impacts during transportation, the chassis and the inner wall of the packaging box are prone to hard contact, resulting in wear of the chassis surface coating, loosening of precision parts, and even structural deformation. This significantly increases transportation losses and subsequent maintenance costs. They usually rely on manual fixing methods such as rope binding and wooden block filling, which are cumbersome to operate and have poor fixing effects.

[0004] To address the aforementioned problems, this application proposes a car chassis packaging box. Summary of the Invention

[0005] The purpose of this utility model is to provide an automobile chassis packaging box to solve the problem of the relatively simple structure in the prior art mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car chassis packaging box, including a packaging box body, a connecting block detachably installed on the upper end of the packaging box body, a protective cover fixedly installed on the upper end of the connecting block, and movable boxes fixedly installed at both ends of the inner cavity of the packaging box body.

[0007] Preferably, a buffer spring is fixedly installed at the lower end of the inner cavity of the packaging box, a movable base plate is fixedly installed at the upper end of the buffer spring, and a support frame is fixedly installed at the rear end of the movable base plate.

[0008] Preferably, the upper end of the support frame has a through hole, a toothed block is fixedly installed on one side of the inner cavity of the through hole, and a gear is movably connected to one side of the toothed block.

[0009] Preferably, an upper gear plate and a lower gear plate are movably connected to the upper outer wall of the gear, a first connecting plate is fixedly connected to one side of the lower gear plate, a first sliding groove is provided on one side of the first connecting plate, and a first fixing plate is fixedly installed on one side of the first sliding groove.

[0010] Preferably, a second connecting plate is fixedly connected to one side of the upper toothed plate, a movable rod is fixedly connected to the lower end of the second connecting plate, a second sliding groove is provided on one side of the movable rod, a second fixing plate is fixedly installed on one side of the movable rod, and limit plates are fixedly installed on one side of the first fixing plate and the second fixing plate respectively.

[0011] Preferably, the number of buffer springs is multiple sets, the gear is located in the inner cavity of the through hole, the upper gear plate is located at the upper end of the gear, and the lower gear plate is located at the lower end of the gear.

[0012] Preferably, the upper toothed plate is movably located in the inner cavity of the first sliding groove, and the lower toothed plate is movably located in the inner cavity of the second sliding groove.

[0013] Preferably, the first fixing plate and the second fixing plate are movably located on both sides of the movable box, and the number of limiting plates is four sets.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes multiple sets of buffer springs, in conjunction with a movable base plate at the top, to provide flexible support for the car chassis placed on the movable base plate. During transport and bumpy conditions, the buffer springs can quickly absorb impact through elastic deformation, preventing hard contact between the chassis and the packaging box body, effectively reducing vibration damage to the chassis's precision structure. Compared to traditional single-structure packaging boxes, the protective performance is significantly improved. The support frame at the rear of the movable base plate, the toothed blocks and gears within the through holes, and the meshing upper and lower toothed plates form a linkage transmission structure. The gravity of the chassis during loading drives the gears to rotate, thereby driving the first connecting plate, the second connecting plate, and the movable rod linkage. The movement causes the first and second fixed plates to move closer to the movable box, and finally the chassis is automatically clamped and limited by four sets of limiting plates. This structure does not require additional manual fixing operations, and the limiting is firm, which can effectively prevent the chassis from lateral displacement during transportation and improve loading stability. The upper toothed plate can slide flexibly in the cavity of the first sliding groove, and the lower toothed plate can adjust its position in the cavity of the second sliding groove. With the meshing transmission of gears and tooth blocks, the clamping range of the first fixed plate, the second fixed plate and the limiting plates can be adaptively adjusted according to the size of different specifications of automobile chassis. There is no need to design a separate packaging box for a specific chassis, which broadens the application range of the device and reduces packaging costs. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1-2 This utility model provides a technical solution: a car chassis packaging box, including a packaging box body 1, a connecting block 2 detachably installed on the upper end of the packaging box body 1, a protective cover 3 fixedly installed on the upper end of the connecting block 2, movable boxes 4 fixedly installed at both ends of the inner cavity of the packaging box body 1, a buffer spring 5 fixedly installed at the lower end of the inner cavity of the packaging box body 1, and a movable base plate 6 fixedly installed on the upper end of the buffer spring 5. Multiple sets of buffer springs 5, together with the upper movable base plate 6, can form flexible support for the car chassis placed on the movable base plate 6. During transportation bumps, the buffer springs 5 ​​can quickly absorb the impact force through elastic deformation, avoiding hard contact between the chassis and the packaging box body 1, effectively reducing the damage of vibration to the precision structure of the chassis. Compared with the traditional single-structure packaging box, the protective performance is significantly improved. A support frame 7 is fixedly installed at the rear end of the movable base plate 6. A through hole 8 is opened at the upper end of the support frame 7. A toothed block 9 is fixedly installed on one side of the inner cavity of the through hole 8, and a gear 10 is movably connected to one side of the toothed block 9.

[0019] In this embodiment, as Figure 3As shown, an upper gear plate 11 and a lower gear plate 12 are movably connected to the upper outer wall of gear 10. Multiple sets of buffer springs 5 ​​are present. Gear 10 is located within the cavity of through hole 8. The upper gear plate 11 is located at the upper end of gear 10, and the lower gear plate 12 is located at the lower end of gear 10. A first connecting plate 13 is fixedly connected to one side of the lower gear plate 12. A first sliding groove 14 is formed on one side of the first connecting plate 13. A first fixing plate 15 is fixedly installed on one side of the first sliding groove 14. A second connecting plate 16 is fixedly connected to one side of the upper gear plate 11. A movable rod 17 is fixedly connected to the lower end of the second connecting plate 16. A second sliding groove 18 is formed on one side of the movable rod 17. The upper gear plate 11 is movably located within the cavity of the first sliding groove 14, and the lower gear plate 12 is movably located within the cavity of the second sliding groove 18. A fixed rod 17 is fixedly installed on one side of the movable rod 17. The first fixed plate 15 and the second fixed plate 19 are respectively fixedly installed on one side of the first fixed plate 15 and the second fixed plate 19. The first fixed plate 15 and the second fixed plate 19 are movably located on both sides of the movable box 4. There are four sets of limit plates 20. With the help of the support frame 7 at the rear end of the movable base plate 6, the toothed block 9 and gear 10 in the through hole 8, and the meshing upper toothed plate 11 and lower toothed plate 12, a linkage transmission structure is formed. The gravity of the chassis during loading can drive the gear 10 to rotate, thereby driving the first connecting plate 13, the second connecting plate 16 and the movable rod 17 to move closer to the movable box 4. Finally, the four sets of limit plates 20 realize the automatic clamping and limiting of the chassis, which can effectively prevent the chassis from lateral displacement during transportation and improve loading stability.

[0020] Working principle: Open the protective cover 3 and place the car chassis on the movable base plate 6 inside the packaging box body 1. Multiple sets of buffer springs 5 ​​fixedly installed at the lower end of the movable base plate 6 will generate adaptive compression according to the weight of the chassis, using elastic deformation to absorb the impact force generated during loading, while providing flexible support for the chassis to avoid damage caused by hard contact. After the chassis is placed, its gravity will drive the support frame 7 at the rear end of the movable base plate 6 to move down synchronously. The gear 10 in the inner cavity of the through hole 8 at the upper end of the support frame 7, which is movably connected to the tooth block 9, will rotate under pressure. Since gear 10 meshes with the upper gear plate 11 at the upper end and the lower gear plate 12 at the lower end respectively, the rotation of gear 10 will drive the upper gear plate 11 and the lower gear plate 12 to move in opposite linear directions. One side of the lower gear plate 12 is connected to the first fixed plate 15 through the first connecting plate 13, and one side of the upper gear plate 11 is fixed to the movable rod 17 through the second connecting plate 16. The movable rod 17 is also equipped with a second fixed plate 19. When the upper gear plate 11 slides along the inner cavity of the first sliding groove 14 and the lower gear plate 12 slides along the inner cavity of the second sliding groove 18, it will drive the first fixed plate 19 to move in opposite directions. Plate 15 and the second fixed plate 19 move closer to the movable box 4. The four sets of limiting plates 20 installed on one side of the first fixed plate 15 and the second fixed plate 19 move synchronously with the fixed plates until they are tightly fitted to both sides of the car chassis, forming multi-directional limiting to prevent the chassis from shifting laterally during transportation. At the same time, the protective cover 3 fixed to the upper end of the packaging box body 1 by the connecting block 2 can block external dust and debris from entering. Combined with the continuous elastic cushioning effect of the buffer spring 5, it can effectively resist the bumps and impacts during transportation and ensure the safety of chassis transportation.

[0021] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
