[0030] Please see Figure 1 and Figure 2 As shown, the present invention provides a pin lifting mechanism 10, which includes a pin assembly 11, an automatic pin lowering assembly 12, and a manual pin lowering assembly 13. The pin assembly 11 is movably installed in the body of the AGV (Automated Guided Vehicle), and can be detachably connected to the material cart. The automatic pin lowering assembly 12 and the manual pin lowering assembly 13 are respectively connected to the pin assembly 11, and can drive the pin assembly 11 to move downward, thereby realizing the unhooking operation from the material cart.

[0031] Please see Figures 1-3 As shown, in this embodiment, the pin assembly 11 includes a mounting base 111, a guide shaft 112, a pin shaft structure 113, and an elastic element 114. The mounting base 111 is fixedly installed in the body of the AGV (Automated Guided Vehicle). The guide shaft 112 is longitudinally fixed on the mounting base 111. The pin shaft structure 113 is movably disposed through the guide shaft 112 and through the mounting base 111, guiding and limiting the lifting and lowering movement of the pin shaft structure 113 via the guide shaft 112. The automatic pin lowering assembly 12 and the manual pin lowering assembly 13 are respectively connected to the pin shaft structure 113. The elastic element 114 is movably disposed through the guide shaft 112 and between the mounting base 111 and the pin shaft structure 113, providing upward support to the pin shaft structure 113, thereby enabling the pin shaft structure 113 to engage with the material cart. Specifically, the elastic element 114 is a spring.

[0032] Please see Figure 3As shown, specifically, a bushing 1111 is fixedly mounted on the mounting base 111, and a pin shaft structure 113 is movably mounted through the bushing 1111, guiding the longitudinal movement of the pin shaft structure 113 through the bushing 1111; through holes 1112 and sliding grooves 1113 are respectively provided on the opposite side walls of the mounting base 111, and the automatic pin lowering component 12 is connected to the pin shaft structure 113 through the through hole 1112, while the manual pin lowering component 13 is connected to the pin shaft structure 113 through the sliding groove 1113; a first inductive switch 1114 and a second inductive switch 1115 are also fixedly mounted on the mounting base 111, and the first inductive switch 1114 and the second inductive switch 1115 respectively sense the movement position of the pin shaft structure 113. Specifically, the pin shaft structure 113 includes a sliding plate 1131, a pin shaft 1132, a first follower wheel 1133, and a sensing screw 1134; the automatic pin lowering assembly 12 is in contact with and driven by the sliding plate 1131, which drives the sliding plate 1131 to move longitudinally; the pin shaft 1132 is fixedly mounted on the sliding plate 1131 and movably mounted on the guide shaft 112, which guides the longitudinal movement of the pin shaft 1132; the first follower wheel 1133 is fixedly mounted on the side of the sliding plate 1131 and slidably mounted in the sliding groove 1113, and the manual pin lowering assembly 13 can be driven by the first follower wheel 1133, thereby driving the pin shaft structure 113 to move downward; the sensing screw 1134 is fixedly mounted on the sliding plate 1131 and can be sensed by the first sensing switch 1114 and the second sensing switch 1115 respectively.

[0033] Please see Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the automatic pin lowering assembly 12 includes a rotary motor 121 and an eccentric structure 122. The rotary motor 121 is fixedly mounted on the side of the mounting base 111, and its output shaft passes through the mounting base 111 via a through hole 1112. The eccentric structure 122 is fixedly mounted on the output shaft of the rotary motor 121 and is connected to the sliding plate 1131. The rotary motor 121 drives the pin shaft structure 113 to move downward through the eccentric structure 122, thereby automatically realizing the disengagement operation of the pin shaft structure 113 from the material cart. Specifically, the eccentric structure 122 includes a cam disk 1221 and a second follower wheel 1222. The cam disk 1221 is fixedly mounted on the output shaft of the rotary motor 121. The second follower wheel 1222 is eccentrically fixed on the cam disk 1221 and is connected to the sliding plate 1131.

[0034] Please see Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, the manual lowering pin assembly 13 includes a mounting cavity 131, a lever 132, and two return springs 133. The mounting cavity 131 is fixedly disposed through the side of the lurking AGV body. The lever 132 is rotatably disposed through the mounting cavity 131 and can contact and drive through the first follower wheel 1133. One end of the two return springs 133 is connected to the lever 132, and the other end is connected to the mounting cavity 131. By pressing the lever 132 to overcome the force of the return springs 133, the pin shaft structure 113 is contacted and driven through, causing the pin shaft structure 113 to move downward, thereby manually realizing the disengagement operation of the pin shaft structure 113 from the material cart.

[0035] Please see Figure 5 As shown, specifically, guide grooves 1311 are symmetrically provided through the opposite sides of the mounting cavity 131, and the two guide grooves 1311 limit and guide the rotation of the lever 132; a rotating shaft 1321 and a sliding shaft 1322 are respectively provided through the lever 132; the two ends of the rotating shaft 1321 are respectively provided on the mounting cavity 131, and the lever 132 rotates relative to the mounting cavity 131 through the rotating shaft 1321; the two ends of the sliding shaft 1322 are respectively slidably provided in the corresponding guide grooves 1311, and the rotation of the lever 132 is limited and guided by the cooperation of the sliding shaft 1322 and the guide grooves 1311.

[0036] Please see Figure 6 As shown, the present invention provides a hidden traction AGV including the pin lifting mechanism 10 of any of the above-mentioned features.

[0037] It should be noted that the specific working process of the pin lifting mechanism and the lurking traction AGV of this utility model is as follows: when the pin lifting mechanism 10 and the material cart need to perform automatic unhooking operation, the rotary motor 121 drives the pin shaft structure 113 to move downward through the cam disk 1221 and the second follower wheel 1222 in sequence. At the same time, the compression elastic element 114 accumulates the restoring force. When the pin shaft structure 113 moves downward to a certain position, the pin shaft structure 113 and the material cart realize the unhooking operation.

[0038] When manual disengagement of the pin lifting mechanism 10 and the material cart is required, pressing the lever 132 forcefully rotates it, causing the lever 132 to contact the second follower wheel 1222 on the pin shaft structure 113, thereby driving the pin shaft structure 113 downward. Simultaneously, the elastic element 114 is compressed to accumulate restoring force. When the pin shaft structure 113 moves downward to a certain position, it disengages from the material cart. When the external force disappears, the pin shaft structure 113 returns to its initial position under the restoring force of the elastic element 114. Simultaneously, the sensing screw 1134 senses the first sensing switch 1114 and the second sensing switch 1115 respectively, achieving precise control of the rotary motor 121.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
