[0014] This design, through the first mounting plate, second mounting plate, connecting block, and third mounting plate forming an extendable plane, greatly improves loading and unloading efficiency and reduces labor intensity. When loading and unloading goods are required, workers can simply slide the mounting plate out of the mounting frame and unfold it to form an unloading platform, allowing goods to easily slide into or out of the truck without manual lifting or carrying, thus reducing physical labor and potential work injury risks. The cylindrical fit design of the sliding rod and the second sliding groove allows the first mounting plate to rotate freely, further adapting to loading and unloading needs at different angles and reducing the frequency of workers adjusting their posture. In addition, the design of the loading and unloading platform also considers... To address the friction issue between cargo and the platform, multiple arc-shaped protrusions are installed on the top of the mounting plate. These protrusions not only guide the cargo to slide smoothly into the truck bed but also reduce friction between the cargo and the platform, making cargo movement smoother. This design not only improves loading and unloading speed but also helps protect cargo from damage and reduces the labor intensity of workers, making the entire loading and unloading process more efficient and safer. At the same time, the design of the support mechanism also ensures the stability of the loading and unloading platform during use. Through the cooperation of the fixed plate and support block, as well as the locking of the plug rod, the platform can be ensured to be stable and reliable during use, preventing cargo from slipping or personnel from falling due to platform instability.

A first installation plate 300 is provided inside the installation frame 205, and the first installation plate 300 is installed inside the installation frame 205 via a movable mechanism. A second installation plate 301 is rotatably provided at the end of the first installation plate 300. A connecting block 302 is rotatably provided at the end of the second installation plate 301. A third installation plate 303 is rotatably connected at the end of the connecting block 302 away from the second installation plate 301. A support mechanism is provided at the bottom end of the third installation plate 303. A shielding mechanism is provided on the installation box 200 to prevent internal components from sliding out.
[0029] The sliding mechanism includes a first sliding groove 201 symmetrically opened on the inner wall of the mounting box 200, a slider 202 slidably disposed in the first sliding groove 201, and the slider 202 is mounted on both ends of the mounting frame 205, and a limiting component is provided on the slider 202.
[0030] The limiting component includes limiting blocks 204 symmetrically arranged on the slider 202, and a limiting groove 203 that cooperates with the limiting blocks 204 is provided in the first sliding groove 201.
[0031] The movable mechanism includes slide rods 305 disposed at both ends of the first mounting plate 300, and the slide rods 305 are cylindrical. The inner walls of the mounting frame 205 are provided with second sliding grooves 306 that cooperate with the slide rods 305.
[0032] The top of the first mounting plate 300, the second mounting plate 301 and the third mounting plate 303 are each provided with a plurality of arc-shaped protrusions 304.
[0033] The support mechanism includes fixed plates 400 symmetrically arranged at the bottom of the third mounting plate 303, a support block 401 rotatably arranged between the two fixed plates 400, and a locking component provided on the fixed plates 400.
[0034] The locking assembly includes a square groove 402 formed at one end of the fixing plate 400 and extending into the support block 401, and a rod 403 is inserted into the square groove 402.
[0035] The shielding mechanism includes a slot 500 formed on the mounting box 200, a baffle 501 slidably disposed in the slot 500, and a bolt 502 for fixing the baffle 501 is provided on one side of the mounting box 200.
[0036] Working principle: When it is necessary to unload the cargo inside the carriage body 100, first remove the bolt 502 to facilitate the downward sliding of the baffle 501. Under the action of the first slide groove 201 and the slider 202, the mounting frame 205 slides out, and under the action of the slide rod 305 and the second slide groove 306, the first mounting plate 300 slides out of the mounting frame 205. Under the action of multiple rotating shafts, the second mounting plate 301, the connecting block 302, and the third mounting plate 303 are rotated to flatten them, and the third mounting plate 300 is then... With end 03 placed on the ground, the first mounting plate 300, second mounting plate 301, connecting block 302, and third mounting plate 303 form a plane. Since the sliding rod 305 is cylindrical, and the second sliding groove 306 is a circular groove that slides in conjunction with the sliding rod 305, the first mounting plate 300 can rotate under the action of the sliding rod 305. When unloading, workers can unload goods from the carriage body 100 through this plane. When loading, simply open the support mechanism. The two insert rods 403 can be pulled out, thereby rotating the support block 401 so that it is perpendicular to the third mounting plate 303. The support block 401 is then placed on the ground, and the insert rods 403 are inserted into the support block 401 along the fixing plate 400, thus placing it on the ground. This makes it convenient for workers to lift the goods onto the mounting plate. With the help of the arc-shaped protrusion 304, the goods can be pushed forward until they enter the box. This design, through the combination of multiple mounting plates and arc-shaped protrusions 304, allows the goods to enter the carriage body 100 more easily, reducing manual handling and lowering the labor intensity of workers. The arc-shaped protrusion 304 can reduce the friction between the goods and the ramp, allowing the goods to move more quickly, thereby improving loading and unloading efficiency and shortening loading and unloading time. When not in use, the first mounting plate 300, the second mounting plate 301, and the third mounting plate 303 can be folded into the mounting box 200, and the sliding baffle 501 blocks the opening and is fixed with bolts 502. During vehicle operation, the internal components slide out.
