[0002] The statements herein only provide background art related to the present invention and do not necessarily constitute prior art.

[0003] With the rise of the Chinese automobile industry, the overseas export volume of Chinese automobiles has been increasing year by year. There are various export transportation methods, and the advantages of sea transportation are prominent. However, the difficulties of sea transportation are extremely challenging. The long sea transportation route, complex weather conditions, and the impact of huge waves on the hull cause the automobiles on the ship to also be tested under various complex working conditions.

[0004] The existing fixing methods for automobile sea transportation containers mainly include three types: 1. Fixing the tire wheel hub; 2. Fixing the subframe; 3. Fixing the front and rear towing hooks. Among them, for the first fixing method, the wheel hub is tied with a strap and then fixed to the fixing frame or the container hook. During sea transportation, under harsh working conditions, the tire wheel hub is easily damaged, and damage to the wheel hub or torque attenuation is likely to occur, resulting in after-sales risks. For the second fixing method, due to the buffer structure of the chassis parts, the relative fixation of the automobile to the container fixing point cannot be effectively controlled under harsh working conditions. After the automobile arrives at the shore, torque attenuation of the chassis parts may occur, and processes such as manual torque inspection and retightening of torque are required, resulting in waste of manpower and potential after-sales risks. For the third fixing method, due to the small number of fixing points and the increase in sea transportation routes in recent years, damage to the vehicle body may occur under extremely harsh working conditions.

Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0034] Embodiment 1

[0035] In a typical implementation manner of the present invention, as Figures 1-5 shown, a vehicle container sea - freight fixing system is provided, including a sea - freight sling, a vehicle body limit frame, and binding straps. The sea - freight sling is installed in the reserved hole 21 at the bottom of the vehicle body. The binding strap passes through the sea - freight sling to fix the vehicle on the vehicle body limit frame. The sea - freight sling includes a hook 15, a washer 16, and a sling 17. A threaded hole is provided on the sling 17, and a thread is provided on the hook. The hook passes through the washer 16 and is installed in the threaded hole of the sling 17 by means of the thread. A groove 23 is provided on the hook body 1502 of the hook 15, and the groove 23 engages with the sheet metal at the reserved hole 21 at the bottom of the vehicle body. By rotating the sling 17, the sheet metal is locked between the washer and the sling.

[0036] As Figure 2 , Figure 3 and Figure 5 shown, one end of the hook 15 is a rod 1501, and the other end is a hook body 1502. The rod 1501 and the hook body 1502 form an inverted L - shaped structure. A thread is provided on the rod 1501. The groove 23 is provided on the lower surface of the hook body and opens downward. Further, the circumference of the reserved hole at the bottom of the vehicle body is bent upward, and the bent edge 22 is located in the groove 23 on the hook body of the hook. During use, the hook body extends into the reserved hole, the bent edge on the reserved hole is located in the groove of the hook body, the end face of the hook body is a plane, and after installation, the end face of the hook body fits with the upper surface of the sheet metal. The outer surface of the hook body is an arc surface, which is convenient for entering the reserved hole and will not cause scratches to the sheet metal.

[0037] Further, a step surface 1503 is provided at the connection position of the rod member 1501 and the hook body 1502, and the step surface 1503 limits the washer 16. Specifically, the inner diameter of the washer 16 matches the diameter of the hook rod, and the outer diameter of the washer 16 is larger than the diameter of the reserved hole at the bottom of the vehicle body, so that the upper surface of the washer can be attached to the lower surface of the vehicle body sheet metal 19, and the inner ring of the washer is attached to the step surface.

[0038] In this embodiment, the surfaces of the hook and the washer in contact with the sheet metal are subjected to plastic coating treatment to form a plastic coating 18, so as to prevent the hanging ring structure from scratching the vehicle body.

[0039] As Figure 1 and Figure 4 shown, the vehicle limit frame is fixed on the container floor by bolts. Tire limit grooves 901 and fixing rings 902 are provided on the vehicle limit frame. The vehicle tires are placed in the tire limit grooves, and the tires are limited by the tire limit grooves 901. Multiple fixing rings are provided on the vehicle limit frame according to needs, and the fixing rings cooperate with the binding straps to position the vehicle.

[0040] In this embodiment, four reserved holes 21 are provided, which are respectively located on the sheet metal at the bottom of the vehicle body behind each wheel.

[0041] The binding straps include tire binding straps and sea transportation binding straps. The tire binding straps cooperate with the fixing rings on the vehicle limit frame to fix the vehicle tires, and the sea transportation binding straps cooperate with the sea transportation hanging rings and the fixing rings on the vehicle limit frame to fix the whole vehicle. As Figure 4 shown, the whole vehicle is specifically fixed by four tire binding straps 1-4, four sea transportation hanging ring binding straps 5-8 and four sea transportation hanging rings 11-14. Due to the limited Z-direction position of the vehicle body fixing points, the binding straps are directly pulled out from the sea transportation hanging rings, which is easy to interfere with the whole vehicle. The fixing rings on the vehicle limit frame change the direction of the binding straps through the hanging rings to avoid interference.

[0042] The usage method of the vehicle container sea transportation fixing system provided in this embodiment is as follows:

[0043] First, assemble the hook 15, the washer 16 and the hanging ring 17 together: first take the hook 15, then the washer 16 with the plastic-coated surface facing up, and put the washer 16 on along the thread of the hook 15. Finally, pre-twist the hanging ring 17 on the thread of the hook 15. The hanging ring 17 is only pre-twisted and does not fall off the hook 15. As long as there is as long a thread as possible reserved between the hook 15 and the washer 16, it is convenient for the hook 15 to pass through the vehicle body sheet metal hole 19 later.

[0044] Next, lift the vehicle by the tooling and the forklift, and the reserved holes at the bottom of the vehicle body can be seen.

[0045] Next, for the assembled marine sling structure 20, first pass the hook 15 (ensure that the contact area between the hook 15 and the vehicle body sheet metal 19 is plastisol-coated to avoid scratching the electrocoating on the vehicle body sheet metal 19) through the hole in the vehicle body sheet metal 19 with the hook orientation of the hook 15 facing towards the inside of the vehicle body, so as to pre-hang the hook on the vehicle body sheet metal 19. After confirming that the hook 15 is hooked on the vehicle body sheet metal 19, rotate the hook 15 as little as possible to avoid scratching the vehicle body sheet metal 19. Then pull the hook 15 downwards, and at the same time tighten the sling 17 upwards along the thread of the hook 15 so that the washer 16 is in contact with the vehicle body sheet metal 19. Note that it is the plastisol-coated side of the washer 16 that is in contact with the vehicle body sheet metal 19 to avoid scratching the electrocoating on the vehicle body sheet metal 19. Repeat the above operations to fix all the marine sling structures 20 on the vehicle body sheet metal 19. Generally, there are 2 slings at the front end of the vehicle body and 2 slings at the rear end of the vehicle body. Finally, pass a metal rod through the sling and retighten the sling.

[0046] The bundling method for the whole vehicle in the container: The whole vehicle limit frame is fixed on the container floor by bolts. The whole vehicle drives into the container, and the tires are limited within the limit frame.
