[0003] The carrying platform of the existing AGV vehicle is usually a fixed structure. Different sizes of AGV vehicles are used when transporting goods of different sizes. Moreover, when handling goods, it is difficult for the current AGV vehicle to limit the goods, resulting in the goods shifting, toppling during transportation, and even being damaged due to unstable clamping. Content of the Utility Model

[0004] The purpose of the utility model is to provide an AGV vehicle convenient for unloading to solve the problems raised in the above background technique.

[0005] It includes an AGV vehicle body. In the middle of the upper end of the AGV vehicle body, a pallet is connected. On one side of the upper end of the pallet, a baffle is connected. On both sides of the upper end of the pallet, conveyor belts are connected. On the upper part of one side of the baffle, a driving component is connected. On both sides of the driving component, side plates are connected. The two side plates are respectively located on both sides of the pallet. On the lower part of one side of the two side plates, guiding components are evenly connected. On the lower part of one side of the two side plates, sliding rods are connected. On both sides of the pallet, chutes are respectively opened corresponding to multiple sliding rods, and the multiple sliding rods are respectively inserted into the multiple chutes.

[0006] In the above technical solution, further, the driving component includes a support rod. The support rod is arranged in an L-shaped structure. At the upper end of the support rod, a motor is connected. The output end of the motor is connected with a gear.

[0007] In the above technical solution, further, the upper end of the gear is meshed and connected with a first rack bar, and the lower end of the gear is meshed and connected with a second rack bar. On one side of the first rack bar and one side of the second rack bar, fixing blocks are connected. The two fixing blocks are respectively located on both sides of the baffle.

[0008] In the above technical solution, further, the guiding component includes a moving cylinder. Rotating balls are circumferentially embedded in the inner wall of the moving cylinder. Rotating grooves are formed in the inner wall of the moving cylinder corresponding to the plurality of rotating balls. The plurality of rotating balls are respectively located inside the plurality of rotating grooves. A supporting roller is rotatably connected to the inner wall of the moving cylinder. One side of the outer wall of the supporting roller contacts one side of the plurality of rotating balls on the inner wall of the moving cylinder. One end of the supporting roller penetrates and extends to one side of the side plate. An opening is formed in the side plate corresponding to the supporting roller, and the supporting roller is located inside the opening.

[0009] In the above technical solution, further, a stabilizing rod is connected to the middle of one side of the inner wall of the moving cylinder. The shape of the stabilizing rod is arranged in an inverted T-shaped structure, and one end of the stabilizing rod penetrates and extends to one side of the supporting roller.

[0010] In the above technical solution, further, a stabilizing groove is formed in one side of the supporting roller corresponding to the stabilizing rod. One end of the stabilizing rod is located inside the stabilizing groove, and the shape of the inner wall of the stabilizing groove is adapted to the shape of one side of the outer wall of the stabilizing rod.

[0012] By adopting the above technical solution, the AGV trolley can automatically unload materials, and the stability of the materials above the AGV trolley is improved.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The motor drives the gear to rotate, which in turn drives the upper end of the gear to mesh with the first rack bar and the lower end to mesh with the second rack bar. Since the tooth directions of the upper and lower rack bars are opposite, when the gear rotates, it will push the two to move in opposite directions. The first rack bar and the second rack bar are respectively connected to the two side plates through fixing blocks. Therefore, when the first rack bar and the second rack bar move, the two side plates will move along the sliding rod to both sides of the supporting plate. The movement of the side plates can change the distance between the two side plates, and the conveyor belt is located on the supporting plate and between the two side plates, so the distance between the two side plates can be adjusted to adapt to the placement of goods of different widths;

[0015] When the side plates move, the moving cylinder moves with the side plates. The supporting roller is embedded in the inner wall of the moving cylinder, and its outer wall contacts the rotating balls. The rotating balls roll in the rotating grooves, converting the sliding friction between the supporting roller and the moving cylinder into rolling friction, reducing the moving resistance of the side plates. The position of the supporting roller remains unchanged, and the supporting roller inside the moving cylinder leaks out. Since the moving cylinder moves to one side, the stabilizing rod slides inside the stabilizing groove, improving the stability of one end of the supporting roller. The other end of the supporting roller rotates on one side of the fixing rod. When the conveyor belt conveys goods, both sides of the lower end of the goods move above the plurality of supporting rollers, and the supporting rollers rotate following the movement of the goods, so as to guide the goods.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: an AGV cart facilitating unloading, which includes an AGV cart body 1. The AGV cart body 1 is self - equipped with a power supply unit. In the middle of the upper end of the AGV cart body 1, a pallet 2 is connected. On one side of the upper end of the pallet 2, a baffle 3 is connected. On both sides of the upper end of the pallet 2, conveyor belts 4 are connected. On the upper part of one side of the baffle 3, a driving component is connected. On one side of the driving component, side plates 11 are connected respectively. The two side plates 11 are located on both sides of the pallet 2 respectively. On the lower part of one side of the two side plates 11, guiding components are evenly connected. On the lower part of one side of the two side plates 11, sliding rods 12 are connected respectively. At the positions corresponding to the multiple sliding rods 12 on both sides of the pallet 2, sliding grooves 13 are respectively opened. The multiple sliding rods 12 are respectively inserted into the multiple sliding grooves 13. The driving component includes a support rod 5. The support rod 5 is arranged in an L - shaped structure. At the upper end of the support rod 5, a motor 6 is connected. At the output end of the motor 6, a gear 7 is connected. At the upper end of the gear 7, a first rack bar 8 is meshed. At the lower end of the gear 7, a second rack bar 9 is meshed. On one side of the first rack bar 8 and on one side of the second rack bar 9, fixing blocks 10 are connected respectively. The two fixing blocks 10 are located on both sides of the baffle 3 respectively;

[0025] The pallet 2 can support the conveyor belt 4. The conveyor belt 4 is convenient for unloading the goods above the AGV cart body 1. The baffle 3 can block one side of the goods. Since the lengths of the first rack bar 8 and the second rack bar 9 are limited, the displacement distance between the two side plates 11 is limited. During the movement of the side plates 11, the sliding rods 12 will always be inside the sliding grooves 13, which can improve the stability of the side plates 11 during movement. The support rod 5 improves the stability of the motor 6. At the same time, the side plates 11 can limit both sides of the goods to ensure the stability of the goods during movement.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figures 5-6, the present utility model provides a technical solution: The guiding assembly includes a moving cylinder 14. Rotating balls 15 are circumferentially embedded in the inner wall of the moving cylinder 14. Rotating grooves are provided in the inner wall of the moving cylinder 14 corresponding to the plurality of rotating balls 15. The plurality of rotating balls 15 are respectively located inside the plurality of rotating grooves. A supporting roller 16 is rotatably connected to the inner wall of the moving cylinder 14. One side of the outer wall of the supporting roller 16 contacts one side of the plurality of rotating balls 15 on the inner wall of the moving cylinder 14. One end of the supporting roller 16 penetrates and extends to one side of the side plate 11. An opening is provided in the side plate 11 corresponding to the supporting roller 16. The supporting roller 16 is located inside the opening. A stabilizing rod 17 is connected to the middle of one side of the inner wall of the moving cylinder 14. The shape of the stabilizing rod 17 is arranged in an inverted T-shaped structure. One end of the stabilizing rod 17 penetrates and extends to one side of the supporting roller 16. A stabilizing groove 18 is provided in the supporting roller 16 corresponding to the stabilizing rod 17. One end of the stabilizing rod 17 is located inside the stabilizing groove 18. The shape of the inner wall of the stabilizing groove 18 is adapted to the shape of one side of the outer wall of the stabilizing rod 17. One side of the plurality of supporting rollers 16 is rotatably connected to a fixing rod 19. The lower end of the fixing rod 19 is connected to the upper end of the supporting plate 2;

[0028] The guiding assembly plays a crucial role in the process of goods handling. When the side plate 11 moves, the moving cylinder 14 moves synchronously. The design of the rotating balls 15 is the key to converting traditional sliding friction into rolling friction. In actual operation, the rolling of the rotating balls 15 in the rotating grooves is extremely smooth, greatly reducing the friction between the moving cylinder 14 and the supporting roller 16, making the movement of the side plate 11 easier. The cooperation between the stabilizing rod 17 and the stabilizing groove 18 provides reliable stability for the supporting roller 16. The rotational connection of one end of the supporting roller 16 to the fixing rod 19 enables it to flexibly adapt to different moving directions of the package. The sliding of the stabilizing rod 17 in the stabilizing groove 18 ensures that the supporting roller 16 will not experience excessive shaking or displacement during operation, always maintaining effective support and guidance for the goods, improving the accuracy and stability of goods handling, and reducing the risk of damage to the goods during transportation.

[0029] Working principle: When in use, adjust the positions of the two side plates 11 according to the width of the goods. Drive the gear 7 to rotate through the motor 6, and then drive the upper end of the gear 7 to mesh with the first rack bar 8 and the lower end to mesh with the second rack bar 9. Since the tooth directions of the upper and lower rack bars are opposite, when the gear rotates, it will push the two to move in opposite directions. The first rack bar 8 and the second rack bar 9 are respectively connected to the two side plates 11 through the fixing blocks 10. Therefore, when the first rack bar 8 and the second rack bar 9 move, the two side plates 11 will move along the sliding rod 12 to both sides of the supporting plate 2. The movement of the side plates 11 can change the distance between the two side plates 11. Since the conveyor belt 4 is located on the supporting plate 2 and between the two side plates 11, the spacing between the conveyor belts 4 can be adjusted in this way to adapt to the placement of goods with different widths;

[0030] When the side plate 11 moves, the moving cylinder 14 moves along with the side plate 11. The idler roller 16 is embedded in the inner wall of the moving cylinder 14, and its outer wall contacts the rotating ball 15. The rotating ball rolls in the rotating groove, converting the sliding friction between the idler roller 16 and the moving cylinder 14 into rolling friction, reducing the moving resistance of the side plate 11. The position of the idler roller 16 is inconvenient, and the idler roller 16 inside the moving cylinder 14 leaks out. Since the moving cylinder 14 moves to one side, the stabilizing rod 17 slides inside the stabilizing groove 18, improving the stability performance of one end of the idler roller 16. The other end of the idler roller 16 rotates on one side of the fixed rod 19. When the conveyor belt 4 conveys goods, both sides of the lower end of the goods move above multiple idler rollers 16, and the idler rollers 16 rotate following the movement of the goods, thereby being able to guide the goods.

[0031] When the AGV cart body 1 moves to the loading area, the conveyor belt 4 operates to guide the goods above the two conveyor belts 4. Multiple idler rollers 16 guide the goods. Subsequently, by adjusting the positions of the two side plates 11, the two side plates 11 clamp both sides of the goods to ensure the stability performance of the goods. When the goods are conveyed to the unloading area, the two side plates 11 release the clamping of the goods. By operating the two conveyor belts 4, the goods above the conveyor belt 4 are driven to one side, and multiple idler rollers 16 guide the goods to ensure the stability performance during the movement of the goods.
