Description

Technical Field

[0001] This utility model relates to an intelligent AGV vehicle, and more particularly to an intelligent AGV vehicle with expandable transport capacity. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Automated Guided Vehicles (AGVs), also known as AGV carts, are transport vehicles equipped with electromagnetic or optical automatic navigation devices. They can travel along a predetermined navigation path and possess safety protection and various transfer functions. In industrial applications, these driverless transport vehicles are powered by rechargeable batteries. Their movement and behavior are typically controlled by a computer, or their path is established using an electromagnetic path-following system. The electromagnetic track is attached to the floor, and the AGV moves based on the information transmitted by the track. In the transportation industry, AGV carts are frequently used to transport goods. When in use, goods are placed directly on the AGV's platform. However, since the platform size is fixed and cannot be adjusted according to the situation, this reduces transport efficiency. Therefore, a smart AGV with scalable transport capacity has been proposed.

[0004] In the prior art, patent publication number CN113998030B describes an intelligent AGV vehicle with expandable transport capacity. This addresses the problem that existing intelligent AGV vehicles have a fixed platform size, which cannot be adjusted according to the site conditions, thus reducing the efficiency of handling.

[0005] The above technical solution solves the problems in the prior art. However, the above technical solution adopts a comb-shaped protrusion structure. However, the plate structure of this protrusion structure is a comb-shaped structure and its width is narrower than the width of the platform. In addition, it adopts a load-bearing structure that can be extended on both sides. After the lower telescopic structure is extended, its height is not on the same plane as the upper layer, resulting in poor load-bearing effect.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] Purpose of the invention: The technical problem to be solved by this utility model is to provide an intelligent AGV trolley with expandable transportation capacity, which addresses the shortcomings of the existing technology.

[0008] To address the aforementioned technical problems, this utility model discloses an intelligent AGV (Automated Guided Vehicle) with expandable transport capacity, comprising:

[0009] The vehicle body has a top surface for carrying objects.

[0010] Drive components are fixedly installed on both sides of the trolley body. The drive components are fixedly connected to the rotating components and drive them to rotate.

[0011] The rotating assembly is fixedly connected to the side of the expansion plate.

[0012] Furthermore, the rotating component drives the extension plate to rotate;

[0013] When the extension plate turns to the trolley body and closes, the extension plate is placed horizontally on the loading plane on the top of the trolley body (1);

[0014] When the extension plate is rotated away from the trolley body and opened, the upper surface of the extension plate is flush with the loading plane.

[0015] Furthermore, the driving component includes:

[0016] A dual-axis motor is installed on the side of the trolley body, and the output ends of the dual-axis motor on both sides are fixedly connected to the worm gear respectively.

[0017] The worm gear drives the rotating assembly to rotate in a vertical plane.

[0018] Furthermore, the rotating assembly includes:

[0019] A rotating shaft meshes with the worm gear, and the rotating shaft is rotatably disposed on the upper side of the trolley body;

[0020] A connecting frame is fixed on the rotating shaft, and the other end of the connecting frame is fixed on the side of the expansion plate.

[0021] Furthermore, a connecting groove is provided on the rotating shaft; a connecting protrusion is inserted into the connecting groove, and the other end of the connecting protrusion is fixedly connected to the connecting frame.

[0022] Furthermore, the connecting frame and the rotating shaft are connected by fixing bolts.

[0023] Furthermore, the connecting frame is connected to the expansion plate via the fixing bolts.

[0024] Furthermore, the inner side of the connecting groove and the outer side of the connecting protrusion have the same shape and mesh with each other.

[0025] Furthermore, the inner side of the connecting groove and the outer side of the connecting protrusion are polygonal in shape.

[0026] Furthermore, the polygon is square.

[0027] Beneficial effects:

[0028] 1. This utility model involves placing goods on top of an extension board and then transporting them via a trolley. When the transport capacity needs to be expanded, a dual-axis motor drives a worm gear to rotate, which in turn drives a worm wheel to rotate. The worm wheel then drives a rotating shaft to rotate, which in turn drives a connecting frame to rotate, thereby rotating the extension board. After the extension board rotates 180 degrees and unfolds, the surface area of ​​the extension board and the trolley body doubles, thus increasing the transport capacity. Since the surface formed by the extension board and the upper part of the trolley body after unfolding is a flat surface with the same width as before, the transport capacity can be doubled.

[0029] 2. This utility model uses a connecting frame to connect to the outer end of the extension plate. The rotating shaft is located on the outside of the connecting plate, and the axis of the rotating shaft corresponds to the lower left corner of the extension plate and the upper left corner of the trolley body, thereby ensuring that the extension plate and the trolley body can form a flat surface after rotation.

Detailed Implementation

[0038] This utility model provides an intelligent AGV trolley with expandable transport capacity. The design principle is as follows: The intelligent AGV trolley includes a vehicle body, four drive wheels are rotatably connected to the side of the vehicle body, the vehicle body is equipped with a drive mechanism and an extension mechanism. The extension mechanism is extended by the drive mechanism to expand the originally overlapping load-bearing surface area, thereby increasing the transport capacity of the trolley. Moreover, the drive mechanism does not require manual operation, which greatly saves manpower and material resources, thereby improving work efficiency and effectiveness.

[0039] The technical solution adopted is:

[0040] A smart AGV (Automated Guided Vehicle) with scalable transport capacity, such as Figure 1 As shown, it includes a trolley body 1, with rotating shafts 20 rotatably mounted on both sides of the trolley body 1, worm gears 30 mounted on the rotating shafts 20, worm gears 31 meshing on the worm gears 30, and a dual-axis motor 32 connected to the worm gears 31.

[0041] like Figure 6 As shown, a connecting groove 21 is provided on the rotating shaft 20;

[0042] like Figure 5 As shown, a connecting protrusion 22 is inserted into the connecting groove 21, and a connecting bracket 23 is connected to the connecting protrusion 22;

[0043] like Figure 4 As shown, the connecting frame 23 and the rotating shaft 20 are connected by fixing bolts 24;

[0044] like Figure 3 As shown, the extension plate 4 is connected to the connecting frame 23 by fixing bolts 24.

[0045] During operation, under normal conditions, goods are transported by placing them on top of the extension plate 4 and then using the trolley body 1. Figure 2 As shown, when it is necessary to expand the cargo transportation capacity, the dual-axis motor 32 drives the worm gear 31 to rotate, the worm gear 31 rotates, the worm wheel 30 rotates, the worm wheel 30 rotates, the rotating shaft 20 rotates, the rotating shaft 20 rotates, the connecting frame 23 rotates, and in turn, the expansion plate 4 rotates. After the expansion plate 3 rotates 180 degrees and unfolds, the surface area of ​​the expansion plate 4 and the trolley body 1 doubles, thereby increasing the transportation capacity. Since the surface formed on the upper part of the expansion plate 4 and the trolley body 1 after unfolding is a flat surface and the surface width is the same as the original, the original transportation capacity can be fully increased by two times. In addition, the rotating shaft 20 is located outside the connecting frame 23, and the axis of the rotating shaft 20 corresponds to the lower left corner of the expansion plate 4 and the upper left corner of the trolley body 1, thereby ensuring that the expansion plate 4 and the trolley body 1 can form a flat surface after the rotation is completed.
