[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see the appendix Figure 1 and attached Figure 2This utility model provides an embodiment of an AGV cargo platform with a folding irregular scissor structure, including a platform 1. Multiple supports 3 are fixedly connected to the top right side of the platform 1. Each support 3 has an inner wall with a groove 13. A fixed shaft 17 is slidably connected to the inner wall of the groove 13. Connecting rods 4 are rotatably connected to the front and rear ends of the outer wall of the fixed shaft 17. A connecting shaft 7 is rotatably connected to the inner wall of the connecting rod 4. A linkage rod 9 is rotatably connected to the outer wall of the connecting shaft 7. A connecting shaft 15 is rotatably connected to the inner wall of the linkage rod 9. Multiple fixing blocks 12 are fixedly connected to the top of the platform 1. The inner wall of fixed block 2 12 is rotatably connected to connecting rod 2 11. The inner wall of connecting rod 2 11 is rotatably connected to connecting shaft 3 16. The outer wall of connecting shaft 3 16 is rotatably connected to connecting rod 2 6. The outer wall of connecting rod 2 6 is rotatably connected to fixed block 1 10. The top of fixed block 1 10 is fixedly connected to shelf 1 27. The bottom of shelf 1 27 is fixedly connected to multiple brackets 2 5. The inner wall of multiple brackets 2 5 is provided with sliding groove 2 14. The top surface of shelf 1 is fixedly connected to cylinder 2 8. The top of shelf 1 27 is fixedly connected to rotating mechanism 2. Rotating mechanism 2 is used to unload goods from AGV cargo platform.
[0033] Specifically, bracket 3 and bracket 5 are fixed to the top right side of the shelf 1 and the bottom of the shelf 27, respectively. A groove 13 is formed on the inner wall of bracket 3 for sliding the fixed shaft 17. A groove 14 is formed on the inner wall of bracket 5 for sliding the connecting shaft 15. Connecting rod 4 is rotatably connected to the front and rear ends of the outer wall of the fixed shaft 17. Its inner wall is rotatably connected to connecting rod 9 via connecting shaft 7. Connecting rod 9 is then connected to groove 14 of bracket 5 via connecting shaft 15, forming a movable connection. Connecting rod 11 is rotatably connected to fixing block 12 on the top of the shelf 1. The inner wall is rotatably connected to the connecting rod 6 via the connecting shaft 3 16. The other end of the connecting rod 6 is rotatably connected to the fixed block 10, which is fixed to the bottom of the shelf 27. These components cooperate to form a complex four-bar linkage mechanism. The cylinder 2 8 is fixed in the middle of the top surface of the shelf 1, and its output end is fixedly connected to the inner wall of the fixed shaft 17. The cylinder 2 8 provides power to the entire scissor linkage mechanism through the extension and retraction of its output end, driving the fixed shaft 17 to slide in the slide groove 13, thereby driving the entire linkage mechanism to move and realize the lifting and lowering of the shelf 27.
[0034] Please see the appendix Figure 4 Appendix Figure 5 and attached Figure 6The rotating mechanism 2 includes a cylinder 204, the bottom of which is threadedly connected to the top of the shelf 27. A sliding block 201 is fixedly connected to the output end of the cylinder 204. A slide rail 207 is slidably connected to the bottom of the sliding block 201. Multiple support rods 208 are rotatably connected to the inner wall of the sliding block 201. Angle brackets 205 are rotatably connected to the outer wall of the multiple support rods 208. Multiple screws 206 are threadedly connected to the inner wall of the shelf 27. A fixing plate 202 is threadedly connected to the outer wall of the screws 206. Multiple fixing plates 203 are fixedly connected to the top right side of the shelf 27.
[0035] Specifically, the sliding block 201 is fixedly connected to the output end of the cylinder 204. Driven by the cylinder 204, it can slide linearly on the slide rail 207. The inner wall of the sliding block 201 is rotatably connected to multiple support rods 208, which are key components for power transmission and conversion. They convert the linear motion of the cylinder 204 into the rotation of the support rods 208. The slide rail 207 provides a stable track for the sliding block 201, ensuring the accurate movement direction of the sliding block 201, reducing friction and resistance during the movement, and improving the efficiency and stability of the transmission. One end of the support rod 208 is rotatably connected to the inner wall of the sliding block 201, and the other end is connected to the second shelf 19 through the angle bracket 205. The arrangement of multiple support rods 208 can distribute the force, enhance the stability and load-bearing capacity of the structure, and ensure that the second shelf 19 can be smoothly pushed to rotate during the unloading of goods. The screw 206 firmly connects the fixing plate 202 to the inner wall of the second shelf 27. The fixing plate 202 may serve as a fixed fulcrum and auxiliary support structure for the rotation of the second shelf 19, providing a stable support foundation for the entire rotating mechanism 2.
[0036] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 A controller 20 is fixedly connected to the front side of the platform 1. The controller 20 is electrically connected to cylinder 28 and cylinder 1 204 respectively. A nameplate 22 is provided near the edge of the front side of the platform 1. Multiple screws 23 are threadedly connected to the inner wall of the nameplate 22. Multiple connecting pieces 25 are fixedly connected to the bottom of the platform 1. A stop valve 24 is rotatably connected to the inner wall of each of the multiple connecting pieces 25.
[0037] Specifically, the controller 20 is electrically connected to cylinder 28 and cylinder 1204 respectively, indicating that it is the control core of the entire system and can accurately control the working state of these two cylinders. The nameplate 22 is threaded to the inner wall of the platform 1 by multiple screws 23. This connection method is firm and reliable, ensuring that the nameplate 22 will not fall off or be damaged during equipment operation and ensuring the long-term readability of information. Multiple stop valves 24 are installed on the inner wall of multiple connecting pieces 25 at the bottom of the platform 1 by rotational connection. This installation method allows the stop valves 24 to rotate freely within a certain angle range, making it easy to adjust their position and direction according to actual usage requirements.
[0038] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 5 The inner wall of the stop valve 24 is rotatably connected to a roller 18, the outer wall of the connecting shaft 2 15 is slidably connected to the inner wall of the slide groove 2 14, the inner wall of the fixing plate 1 202 is rotatably connected to a fixing shaft 2 26, the outer wall of the fixing shaft 2 26 is fixedly connected to a storage plate 2 19, the front and rear ends of the fixing shaft 1 17 are fixedly connected to a clamping plate 21, and the output end of the cylinder 2 8 is fixedly connected to the inner wall of the fixing shaft 1 17.
[0039] Specifically, the inner wall of the stop valve 24 is rotatably connected to the roller 18. This design allows the roller 18 to rotate relatively freely inside the stop valve 24. The outer wall of the connecting shaft 15 is slidably connected to the inner wall of the slide groove 14. This structure allows the connecting shaft 15 to make linear sliding motion within the limited range of the slide groove 14. The slide groove 14 provides guidance and constraint for the movement of the connecting shaft 15, ensuring that its movement trajectory is accurate and there will be no deviation or shaking. The inner wall of the fixing plate 202 is rotatably connected to the fixing shaft 26, and the outer wall of the fixing shaft 26 is fixedly connected to the shelf 19. The shelf 19 can rotate relative to the fixing plate 202 around the fixing shaft 26. The fixing plate 202 provides a fixed fulcrum for the rotation of the shelf 19, so that the shelf 19 can achieve a flipping action under the action of the cylinder, which is used for loading and unloading goods and position adjustment.
[0040] Working principle: First, after cylinder 28 starts, its output end generates thrust and pull. Since the output end of cylinder 28 is fixedly connected to the inner wall of fixed shaft 17, this force will directly act on fixed shaft 17, causing fixed shaft 17 to slide within the slide groove 13 opened in the inner wall of bracket 3. The front and rear ends of the inner wall of connecting rod 4 are rotatably connected to the outer wall of fixed shaft 17. When fixed shaft 17 slides, it will cause connecting rod 4 to rotate around fixed shaft 17. At the same time, the inner wall of connecting rod 4 is also rotatably connected to connecting shaft 7, and the outer wall of connecting shaft 7 is rotatably connected to linkage rod 9. This allows connecting rod 4 to transmit force to linkage rod 9 during rotation, causing linkage rod 9 to move together. Multiple fixed blocks 22 are fixedly connected to the top of the platform 1. The inner walls of multiple fixed blocks 22 are rotatably connected to linkage rod 21, and the inner walls of linkage rod 21 are rotatably connected to... A connecting shaft 16 is rotatably connected to a connecting rod 6 on its outer wall. A fixing block 10 is rotatably connected to the outer wall of the connecting rod 16. A shelf 27 is fixedly connected to the top of the fixing block 10. While the connecting rod 4 drives the linkage rod 9 to move, the linkage rod 11 also forms a four-bar linkage mechanism with the linkage rod 9, the connecting rod 4, and the connecting rod 26 through its rotatable connection with the connecting rod 26 and the fixing block 12. Therefore, when the cylinder 28 pushes the fixing shaft 17 to slide to the right, the angle between the connecting rod 4 and the linkage rod 9 increases, and the angle between the linkage rod 21 and the connecting rod 26 also changes accordingly, pushing the shelf 27 to rise. Conversely, when the cylinder 28 pulls the fixing shaft 17 to slide to the left, the angles of each rod decrease, and the shelf 27 lowers. Through this four-bar linkage, the overall structure can be smoothly raised and lowered, which can meet the needs of AGV cargo platforms for loading and unloading goods at different heights.
[0041] Then, when cylinder 204 is started, its output end will move linearly in a set direction. Since the output end of cylinder 204 is fixedly connected to sliding block 201, the force of this linear motion will be directly transmitted to sliding block 201, causing sliding block 201 to slide left and right within slide rail 207. Slide rail 207 provides stable guidance for the movement of sliding block 201, ensuring that sliding block 201 can only move along a predetermined linear trajectory. Since support rod 208 and sliding block 201 are rotatably connected, support rod 208 will rotate relative to sliding block 201, causing the angle between support rod 208 and the horizontal plane to gradually change. As the angle between the support rod 208 and the horizontal plane increases, the support rod 208 will exert a force on the second shelf 19 through the corner bracket 205. Since the second shelf 19 can rotate around the second fixed axis 26, under the push of this force, the second shelf 19 will rotate around the second fixed axis 26. As the sliding block 201 continues to move, the angle of the support rod 208 continues to increase, and the rotational force on the second shelf 19 also continues to increase, so that the rotation angle of the second shelf 19 gradually increases. When the second shelf 19 rotates to a certain angle, the goods on it will slide down the inclined surface of the second shelf 19 due to the action of gravity, thereby achieving the purpose of quick unloading.
