The design of the tail box takes into account efficiency, flexibility and safety, and can meet various tactical needs. In terms of structure, the tail box has a large volume, can accommodate a large amount of materials and personnel, and ensures high carrying capacity and stability. Reinforced steel is often used at the bottom of the tail box, the side walls and roof may be protected by armor plates or composite materials to provide ballistic and blast resistance. In addition, the tail box is equipped with shelves and fixing devices for easy loading and unloading to ensure the safety and stability of the materials during transportation, and the seat and armrest design ensures that personnel can quickly get on and off the vehicle. However, the current design of the tail box of the military truck usually makes the tail part higher from the ground, which is mainly to enhance the passability and carrying capacity of the vehicle, especially the driving ability on poor roads. However, this also poses a problem, that is, when personnel climb into the tail box of the vehicle, the personnel entering need to have certain upper limb and jumping ability. In an emergency, users need to quickly enter the tail box for evacuation or combat preparation. If the height of the tail box is too high, users not only need to spend extra time to climb and jump into the tail box, but also need certain physical strength and skills to ensure safety. For physically weak or injured personnel, the entry speed will be further reduced, affecting the overall transfer efficiency. SUMMARY

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts fall within the protection scope of the utility model.
[0020] Please refer to Figures 1-5 , the utility model provides an embodiment: a vehicle tail box climbing assembly, including U-shaped outer back frame 1 and inverted U-shaped inner frame 2 that is slidably installed on the left and right inner walls of U-shaped outer back frame 1, the top of inverted U-shaped inner frame 2 penetrates to the outside of U-shaped outer back frame 1, the left and right outer walls of U-shaped outer back frame 1 are provided with quick lock structure for locking U-shaped outer back frame 1 and inverted U-shaped inner frame 2, the top of inverted U-shaped inner frame 2 is integrally formed with right-angled buckle plate 3, the left and right inner walls of inverted U-shaped inner frame 2 are fixed with vertical plate, the same side outer wall of two vertical plates is installed with several equidistant cross beams 6 in the vertical direction, and the side outer wall of cross beam 6 away from vertical plate is provided with two symmetrical folding type footrest arms 7;
[0021] The user can also place both hands on the top edge of the trunk door or hold other parts of the vehicle body, and use the folding footrest arm 7 to assist the user's lower limbs to enter the trunk;
[0022] The U-shaped outer back frame 1, the inverted U-shaped inner frame 2, and the right-angle buckle plate 3 are all made of aluminum alloy components. The right-angle buckle plate 3 has a completely penetrating square hollow part on both sides.
[0023] The quick locking structure includes a plurality of equally spaced positioning holes 4 arranged on the outer walls of the inverted U-shaped inner frame 2 and a plurality of elastic positioning pins 5 installed on the left and right outer walls of the U-shaped outer back frame 1. The elastic positioning pin 5 is concentric with one of the positioning holes 4, and the plurality of positioning holes 4 are on the same vertical extension line. The user pulls the inverted U-shaped inner frame 2 upwards, so that the combined length of the inverted U-shaped inner frame 2 and the U-shaped outer back frame 1 is extended. At this time, the inverted U-shaped inner frame 2 is buckled on the trunk door plate through the right-angle buckle plate 3, and the bottom end of the U-shaped outer back frame 1 is in contact with the ground. Then, the U-shaped outer back frame 1 and the inverted U-shaped inner frame 2 are locked by the cooperation of the positioning holes 4 and the elastic positioning pins 5.
[0024] The folding footrest arm 7 includes shaft plates 701 fixed at both ends of the cross beam 6, a support column 702 fixed between the two shaft plates 701, and a square connection sleeve 703 sleeved on one end of the surface of the support column 702. The bottom end of the square connection sleeve 703 is fixed with a footrest arm body 704, and the surface of the cross beam 6 is provided with a notch part 601 for the square connection sleeve 703 to flip over.
[0025] When operating the folding footrest arm 7, the user holds the end of the footrest arm body 704 and flips the footrest arm body 704 and the square connection sleeve 703 downwards, so that the footrest arm body 704 and the square connection sleeve 703 are deflected around the support column 702 until the footrest arm body 704 is in a parallel state. It can be quickly folded and stored when not in use, keeping the space of the trunk clean and complete, and can be quickly unfolded when needed.
[0026] The U-shaped outer back frame 1 and the inverted U-shaped inner frame 2 are in a folded state and are tightly combined and placed in the trunk of the vehicle before use, at which time all components of the assembly are in a folded and locked state when not in use, so as to maximize the use of the trunk space of the vehicle and avoid hindering the storage of goods in the vehicle. When a person needs to enter the trunk, the U-shaped outer back frame 1 and the inverted U-shaped inner frame 2 are unlocked through the quick lock structure, and after being unlocked, the inverted U-shaped inner frame 2 can be quickly pulled out upward from the U-shaped outer back frame 1 until the inverted U-shaped inner frame 2 is pulled to the desired length, and then the U-shaped outer back frame 1 and the inverted U-shaped inner frame 2 are locked through the quick lock structure, and a stable climbing platform is provided by the U-shaped outer back frame 1 and the inverted U-shaped inner frame 2. Next, the inverted U-shaped inner frame 2 is fixed against the door panel of the trunk of the vehicle through the right-angled buckle plate 3, ensuring that the assembly and the trunk door do not loosen during operation. When the L-shaped structure of the right-angled buckle plate 3 contacts the trunk door of the vehicle, it can be quickly and firmly buckled, thereby preventing the U-shaped outer back frame 1 and the inverted U-shaped inner frame 2 from shifting or becoming unstable during climbing, and enhancing the support of the entire frame. After the frame is fully unfolded and fixed, each folding footrest arm 7 needs to be unfolded manually one by one. The unfolded folding footrest arms 7 form a structure similar to a ladder, on which the user can step and be stably supported at each step to gradually climb to the height of the trunk. The user can stand between the two rows of folding footrest arms 7, and each folding footrest arm 7 acts like a step, allowing the user to use it like a ladder, with both feet placed on the folding footrest arms 7 in turn to gradually climb upward. The person who has already entered the trunk can also pull the climber with both hands to assist him in climbing upward. Once the user climbs to the edge of the trunk, he can place his hands on the edge of the trunk or grab other parts of the vehicle body to complete the final action of climbing, at which time the right-angled buckle plate 3 and the quick lock structure on the trunk door remain stable. After the user successfully enters the trunk, the folding footrest arms 7 can be folded back by reversing the operation and the assembly can be removed from the trunk door.
