[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] A specific embodiment of this utility model provides a compact, ultra-thin AGV, combined with an attached... Figure 1 As shown, it mainly includes an AGV frame 1 and a lifting mechanism. In this embodiment, the AGV frame 1 is set as a rectangle. Drive wheels and support wheels are set at the bottom of the AGV frame 1 for the movement of the AGV vehicle. The lifting mechanism is embedded in the AGV frame 1. At the same time, a power supply device 11 and a control system 12 are embedded in the AGV frame 1. The power supply device 11 uses a lithium battery to provide power to the lifting mechanism and the control system 12. The control system 12 is electrically connected to the lifting mechanism and the drive wheels. A navigation system is built into the AGV frame 1 for running path identification.

[0026] Specifically, such as Figure 2 , Figure 3As shown, the lifting mechanism includes a base 2, an upper frame assembly 3, a guide seat 4, a drive motor 5, a reducer 6, and a detection switch 7. The guide seat 4 and the base 2 are bolted together. The base 2 has four mounting seats 21 symmetrically arranged. The number of drive motors 5 and reducers 6 is the same as the number of mounting seats 21. The reducers 6 are bolted together to the top of the mounting seats 21. The reducers 6 are arranged symmetrically in pairs, and the output ends of the reducers 6 are arranged in opposite directions. The drive motor 5 and the reducers 6 are bolted together. The detection switch 7 is bolted together to the base 2.

[0027] Specifically, the upper frame assembly 3 includes a frame body 31, guide wheel devices 32, limit seats 33, and switch sensing plates 34. The frame body 31 is a rectangular frame, and two support rods 311 are arranged parallel to each other in the inner circle of the frame body 31, dividing the frame body 31 into three equal areas. The central area can be left empty for the placement of other equipment, and the two side areas are equipped with guide wheel devices 32 and switch sensing plates 34. The frame body 31 at opposite ends of the two side areas is equipped with... The frame body 31 is bolted to a limit seat 33. The drive wheel device 32 is provided with a support column 321. On both sides of the support column 321, there are two moving wheels 323. The support column 321 is provided with two moving wheels on one side, arranged in a vertical line. The guide seat 4 is provided with a guide groove 41. The guide wheel 322 and the guide groove 41 are slidably connected. Since the position of the guide groove 41 is fixed, the lifting and lowering of the frame body 31 is limited by the movement of the guide wheel 322 in the guide groove 41. It can only move in the direction of the groove of the guide groove 41.

[0028] Specifically, an eccentric crankshaft 61 is provided at the output end of the reducer 6. Since the reducer 6 is mounted on the mounting base 21, a height difference is formed between the reducer 6 and the base 2. A support roller 62 is provided at the other end of the eccentric crankshaft 61. The support roller 62 is located in the limiting seat 33. The four limiting seats 33 correspond to the four positions of the reducer 6. When the eccentric crankshaft 61 rotates, the support roller 62 rotates in the limiting seat 33, ensuring lifting and limiting the position of the frame body 31 relative to the base 2. The drive motor 5 drives the reducer 6. The eccentric crankshaft 61 at the output end of the reducer 6 drives the frame body 1 to move through the height difference. Due to the guide groove 41 of the guide seat 4, the frame body 1 can only move vertically up and down.

[0029] Specifically, the detection switch 7 is equipped with a first switch 71 and a second switch 72, wherein the first switch 71 is located above the second switch 72. The switch sensing plate 34 corresponds to the detection switch 7. When the frame body 31 is in a low position, the switch sensing plate 34 faces the second switch 72 in the detection switch 7. When the lifting platform is in a high position, the switch sensing plate 34 faces the first switch 71 located above the detection switch 7. The function of the detection switch 7 is to detect the low and high positions of the frame body 31 and eliminate the cumulative error caused by the repetitive operation of the motor.

[0030] In this embodiment, four driving lifting mechanisms are used for lifting. The motor can be directly connected to the reducer and crankshaft, eliminating the need for an additional power transmission system to transmit the motor's power to the four crank lifting points of the lifting platform. This greatly reduces the space occupied by the lifting platform components. Furthermore, the minimum height of the frame body is consistent with the height of the AGV frame 1. The embedded design realizes the integrated design of the AGV frame 1 and the lifting mechanism. Equipment can be arranged in the placement slots of other equipment and the lifting mechanism within the AGV frame 1, greatly improving the integration.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
