[0032] Example 1

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figures 1 to 9 As shown, an AGV (Automated Guided Vehicle) for easy loading includes a vehicle body 1, at least two support legs 11, and at least two forks 12. An opening / closing assembly 2 connects the support legs 11 to the vehicle body 1. A linkage mechanism 3 is provided between the two opening / closing assemblies 2. A rotating component 4 is provided on each fork 12, and a support assembly 5 is slidably disposed within each fork 12. An auxiliary component 6 is also provided along the movement path of the rotating component 4. The opening / closing assembly 2 is used to drive the support legs 11 to unfold or close under the action of the linkage mechanism 3. The support assembly 5 is used for loading goods onto the forks 12. During the upward movement, the fork arm 12 is supported by the downward sliding of the rotating part 4 and the auxiliary part 6. First, before loading the large cargo 13, the support legs 11 on both sides of the vehicle body 1 are extended to both sides, and the fork arm 12 is lowered to the lowest point. After loading the cargo 13, the fork arm 12 moves upward, and the support block 52 extends downward to support the fork arm 12. Then the support leg 11 rotates inward to return to its original position. When the fork arm 12 descends again, the support block 52 is pulled back upward into the fork arm 12 by gravity.

[0035] like Figure 2 As shown, the opening and closing assembly 2 includes a fixed plate a21 and a fixed plate b22 fixedly mounted on the vehicle body 1. A first rotating shaft 23 is rotatably mounted between the fixed plate a21 and the fixed plate b22. A connecting plate 24 is fixedly mounted on the support leg 11. The connecting plate 24 is rotatably mounted on the first rotating shaft 23. A first gear 25 is rotatably mounted between the connecting plate 24 and the fixed plate a21. The first gear 25 is coaxial with the first rotating shaft 23.

[0036] likeFigure 4 As shown in the figure, the linkage mechanism 3 comprises a rotating assembly 7 and a transmission assembly 8. The rotating assembly 7 comprises a fixed frame 71 fixedly arranged on the vehicle body 1, a threaded rod 72 rotatably arranged on the fixed frame 71, a first rack 73 fixedly connected to one end of the threaded rod 72, and a rocker 74 fixedly connected to the other end of the threaded rod 72. The first rack 73 is fixedly arranged with limit blocks 75 on both sides, and the limit blocks 75 are slidingly arranged on the inner side of the fixed frame 71.

[0037] As shown in the figure, Figure 3 The transmission assembly 8 comprises a rotating shaft 81, a driving gear 82 rotatably arranged in the middle of the rotating shaft 81, and a driven gear 83 rotatably arranged on both ends of the rotating shaft 81. The driving gear 82 is engaged with the first rack 73, and the driven gear 83 is engaged with the first gear 25. A rotating seat 84 is sleeved on the rotating shaft 81, and the rotating seat 84 is fixedly arranged on the vehicle body 1. By arranging the rotating assembly 7, during the rotation of the threaded rod 72, the first rack 73 slides towards the driving gear 82 and rotates the driving gear 82 and the driven gears 83 on both sides under mutual engagement, while driving the first gear 25 to rotate, realizing that the supporting legs 11 can be expanded outward before the AGV carrier loads the wider and lower goods 13, and the fork arms 12 are lowered to the lowest position for loading the goods 13, solving the problem that the original fork arms 12 can only be lowered to the position where the rollers 15 of the supporting legs 11 are flush, some wider goods 13 and lower goods 13 cannot be loaded, and improving the versatility of the AGV carrier.

[0038] As shown in the figure, Figure 3 The supporting assembly 5 comprises a second rack 51 slidingly arranged in the fork arm 12 and a supporting block 52 fixedly arranged on the lower end face of the second rack 51. By arranging the second rack 51, the third rack 61, the second gear 43, and the third gear 44, when the fork arm 12 moves upward, the second gear 43 rotates counterclockwise under the engagement of the second gear 43 and the third rack 61, driving the third gear 44 to rotate clockwise and driving the second rack 51 to move downward, so that the supporting block 52 also moves downward to support the fork arm 12, and after loading the goods 13, the supporting legs 11 reduce the frictional force with the ground when returning to the original position.

[0039] As shown in the figure, Figure 3 The rotating member 4 comprises a connecting block 41 fixedly arranged on both sides of the fork arm 12, a second rotating shaft 42 and a third rotating shaft 45 rotatably arranged between the two connecting blocks 41, a second gear 43 rotatably arranged on the second rotating shaft 42, and a third gear 44 rotatably arranged on the third rotating shaft 45. The second gear 43 is engaged with the third gear 44, and the third gear 44 is engaged with the second rack 51.

[0040] As shown in the figure, Figure 2As shown, the auxiliary component 6 includes a third rack 61 fixedly mounted on the vehicle body 1, and the third rack 61 meshes with the second gear 43.

[0041] like Figure 3 As shown, a blocking component 9 is also provided above the rotating component 4. The blocking component 9 includes a lifting rod 91 slidably disposed in the fork arm 12, a push-pull rod 92 fixedly disposed on the upper end face of the lifting rod 91, and telescopic protrusions 93 slidably disposed on both sides of the lifting rod 91. A telescopic rod 94 and a spring 95 are fixedly disposed at the tail end of the telescopic protrusions 93. By setting the lifting rod 91 and the telescopic protrusions 93 slidably disposed in the lifting rod 91, when the support block 52 is fully extended, the telescopic protrusions 93 are locked between the second gear 43 and the third gear 44 when the lifting rod 91 descends, preventing the second gear 43 and the third gear 44 from rotating, causing the support block 52 to move upward. This method effectively improves the stability and sturdiness of the support block 52.

[0042] like Figure 2 As shown, a limit plate 14 is also provided on the inner side of the support leg 11. The limit plate 14 is fixedly installed on the vehicle body 1. By setting the limit plate 14, the support leg 11 can only rotate outward, preventing the support leg 11 from rotating inward, thus playing a limiting role.

[0043] like Figure 1 As shown, a roller 15 is rotatably mounted on the front end of the support leg 11, and the roller 15 is made of wear-resistant material.

[0044] Example 2

[0045] like Figure 1 As shown, the components that are the same as or corresponding to those in Embodiment 1 are referred to by the same reference numerals as those in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that the outer ring of the roller 15 is made of thermoplastic polyurethane elastomer.

[0046] In this embodiment, the outer ring of the roller 15 is made of thermoplastic polyurethane elastomer, which has the advantages of low resistance, low shrinkage rate and long service life, which helps the support leg 11 to rotate smoothly to its original position.
