[0025] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Example

[0027] like Figure 1 As shown, the utility model proposes a trailer cargo positioning component, including a trailer cargo compartment 1, and also includes: two push plates 8 are slidably installed in the cargo compartment 1, and a driving device is provided in the cargo compartment 1 to drive the push plates 8 to move, which plays an auxiliary positioning role in cargo positioning, and elastic contact components that deform according to the shape of the cargo are provided on opposite sides of the two push plates 8.

[0028] like Figure 6 As shown, the elastic contact assembly includes a plurality of springs 9 fixed on the push plate 8, and the plurality of springs 9 are arranged in an array along the length direction of the push plate 8. A positioning rod 16 is fixed at one end of the spring 9, and the positioning rod 16 can be replaced with an appropriate length according to the needs of different goods. The deformation of the spring 9 drives the positioning rod to adjust and position goods of different shapes. A rubber pad 17 is fixed on the top of the positioning rod 16, and the rubber pad 17 can reduce damage to the goods during the positioning process and avoid unnecessary losses. It can also be replaced with polyurethane material. By adjusting the movement of the push plate 8, the position of the positioning rod 16 is adjusted to contact the goods until the spring 9 is compressed and matched with the plurality of positioning rods 16 to adjust the clamping position according to the shape of the clamped surface of the goods, so as to achieve the clamping and positioning of irregularly shaped goods and improve the stability of the positioning of irregular goods.

[0029] like Figure 6As shown, the elastic contact assembly also includes a positioning mechanism for fixing the positioning rod 16, the positioning mechanism includes a lower clamping plate 21 fixedly installed inside the cargo warehouse 1, a fixing seat 15 is fixedly installed at the bottom of the cargo warehouse 1, the top of the fixing seat 15 is fixedly connected to the first motor 7, a threaded rod 14 is rotatably connected to the bottom of the inner wall of the cargo warehouse 1, the fixing seat 15 cannot interfere with the rotation of the threaded rod 14, the threaded rod 14 is threadedly connected to the upper clamping plate 20 through a fixing block with a thread, and a pulley 11 and a pulley 2 13 are fixedly installed on the top of the threaded rod 14, a belt 12 is installed between the pulley 11 and the pulley 2 13, and the pulley 11 is rotatably connected to the output end of the first motor 7. The upper clamping plate 20 and the lower clamping plate 21 are of the same length, and a plurality of semicircular grooves are provided in parallel on the lower side of the upper clamping plate 20 and the opposite side of the lower clamping plate 21. The semicircular grooves are concentric with the positioning rod 16 but have different diameters. The diameter of the semicircular grooves shall not be greater than or equal to the diameter of the positioning rod 16, so that the positioning rod 16 will not slide in the circular grooves when clamped, thereby achieving the function of fixing the positioning rod. After the positioning rod 16 is deformed and the driving device completes the action, the threaded rod 14 is driven downward by the first motor 7, and the upper clamping plate 20 connected to the threaded rod 14 is also squeezed downward to complete the fixation of the positioning rod 16, thereby enhancing the stability during transportation and avoiding the shaking of the goods during transportation due to the elasticity of the spring 9 itself.

[0030] like Figure 6 As shown, the driving device includes a bidirectional screw rod 19 rotatably installed in the cargo hold 1, a second motor 10 is fixedly installed at the bottom of the inner wall of the cargo hold 1, and the output end of the second motor 10 is movably connected to the bidirectional screw rod 19, the bidirectional screw rod 19 is threadedly connected to two push plates 8, two guide rods 18 are fixed in the cargo hold 1, and the push plates 8 are slidably sleeved on the guide rods 18. After the positioning rod 16 completes the first stage of positioning of the goods, the second motor 10 is started, and the two push plates 8 are driven to move inward through the bidirectional screw rod 19, and the positioning rod 16 that cannot contact the goods is squeezed inward, thereby completing the positioning effect and improving the stability of the goods.

[0031] like Figure 4-5 As shown, a lifting mechanism 22 is provided inside the bottom of the cargo warehouse 1. The lifting mechanism 22 includes a lifting plate 3 slidably installed between two lower clamping plates 21. A cylinder 2 is fixed inside the bottom of the cargo warehouse 1. The piston rod of the cylinder 2 is fixed on the lifting plate 3. The purpose of setting two groups of cylinders 2 is to ensure that the lifting plate 3 is balanced when lifting and lowering to prevent the goods from tipping over. For goods of different heights, the positioning rod 16 may not be able to touch the goods. In this case, under the action of the cylinder 2, the lifting plate 3 can be lifted to a position where the positioning rod can touch the goods, thereby improving the fault tolerance of the positioning mechanism. The surface of the lifting plate 3 is coated with an epoxy resin protective layer, which cooperates with the rubber pad 17 to reduce the wear on the goods during handling and transportation. Similarly, it can also be replaced with natural rubber.

[0032] like Figure 5 As shown, four guide rods 5 are fixed to the bottom of the inner wall of the cargo hold 1, and the four guide rods 5 are slidably connected to the four corners of the lifting plate 3 through the fixing blocks 4. The top of the guide rods 5 is fixedly installed with a limiting block 6. The four guide rods 5 play a guiding role in the lifting process of the lifting plate 3.

[0033] Working principle: Place the goods on the lifting plate 3, and use the second motor 10 to drive the two push plates 8 to move inward at the same time, adjust the position of the positioning rod 16 to contact the goods, until the spring 9 is compressed and cooperates with multiple positioning rods 16 to adjust the clamping position according to the shape of the clamped surface of the goods, so as to achieve the clamping and positioning of irregularly shaped goods and improve the stability of positioning of irregular goods. Furthermore, the first motor 7 is started to drive the threaded rod 14 to rotate, and the upper clamping plate 20 threadedly connected to the threaded rod 14 moves downward, and the positioning rod 16 is clamped and fixed by the upper clamping plate 20 and the lower clamping plate 21 to prevent the goods from shaking due to the deformation of the spring 9 during transportation, and further assist in fixing the goods to improve the fixing effect of irregular goods.
