Description

Technical Field

[0001] The utility model relates to the technical field of AGV robots, in particular to a folding-frame AGV robot. Background Art

[0002] An AGV robot (Automated Guided Vehicle) is a handling device integrating automation and intelligent technologies. Through advanced navigation and obstacle avoidance systems, it can autonomously complete tasks such as item handling and transfer, and is widely used in industries such as automotive, home appliance, hardware, electronics, textile, warehousing, clothing, chemical industry, food, and papermaking, as well as various automated logistics distribution production systems. It can not only reduce the labor intensity of workers, improve the material handling efficiency, but also achieve unmanned transportation, reducing labor and operation costs. The design of the folding frame enables the robot to save space in the non-working state, facilitating storage and transportation.

[0003] Currently, common automated guided vehicles are often designed to be relatively small in order to cope with changing driving paths and complex working environments. However, the small size results in the load platform above the automated cart being unable to carry too many goods, leading to a lack of work efficiency. If the load platform is enlarged, the space occupied by the cart will be too large. Based on this, a folding-frame AGV robot is proposed, which can increase the quantity of goods that can be carried per transportation and improve the transportation efficiency.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0026] Embodiment 1:

[0027] Refer to Figures 1 - 5 , a folding frame AGV robot, including a vehicle body 1, further including: a first extension plate 23 is connected to the vehicle body 1 through a rotating shaft, and a second extension plate 24 is connected to the first extension plate 23 through a rotating shaft; a chute 241 is opened on the second extension plate 24, and a support plate 32 slides on the chute 241; a driven wheel 31 is connected to the lower side of the support plate 32 through a rotating shaft.

[0028] In the present utility model, a cylindrical rotating shaft is inserted into the support plate 32, and the cylindrical rotating shaft is clamped inside the chute 241, so that the support plate 32 can rotate while sliding inside the chute 241, and further, the driven wheel 31 can always keep in contact with the ground during the movement of the second extension plate 24 to provide a supporting force for the extended part.

[0029] Since the main supporting force of the extended part is provided by the driven wheel 31, the number of the driven wheels 31 and the support plates 32 can be added according to the upper limit of the mass to be carried. It is only necessary to open a plurality of grooves 241 on the second extension plate 24 and install the support plates 32 and the driven wheels 31 inside the chute.

[0030] When the first extension plate 23 and the second extension plate 24 are folded, their tops can support the lifting of goods and act as an adjustable lifting platform.

[0031] Embodiment 2:

[0032] Referring to Figures 1 - 5 , which is basically the same as Embodiment 1. Further: A plurality of support rods 22 are vertically fixed on the upper surface of the second extension plate 24. The lengths of the support rods 22 increase sequentially from bottom to top. The support rods 22 are connected with insertion rods 25 through rotating shafts. A telescopic sleeve rod 21 is sleeved on the insertion rod 25. A moving rod 45 is fixedly connected to the side wall of the support plate 32. The moving rod 45 is inserted and slid on the side wall of the vehicle body 1. The moving rod 45 is inserted with a threaded rod 44 through a thread. A driven bevel gear 43 is fixed on the threaded rod 44. A fixed plate 46 is fixed inside the vehicle body 1. The threaded rod 44 is inserted on the fixed plate 46. A servo motor 41 is fixed inside the vehicle body 1. The output end of the servo motor 41 is fixedly connected with a driving bevel gear 42. The driving bevel gear 42 meshes with the driven bevel gear 43. A driving wheel 11 is connected to the vehicle body 1 through a rotating shaft.

[0033] In the present utility model, the lengths of the support rods 22 increase sequentially from bottom to top, so that the telescopic sleeve rod 21 can still form a guardrail to protect the goods after the second extension plate 24 is extended. The thicknesses of the support rods 22 increase sequentially from top to bottom and extend outwards. The connection positions of the insertion rods 25 and the support rods 22 extend outwards sequentially from top to bottom, so as to prevent the lower insertion rod 25 from touching the upper support rod 22 during the movement of the second extension plate 24.

[0034] The fixed plate 46 is used to limit and support the threaded rod 44, so as to ensure the meshing of the driven bevel gear 43 and the driving bevel gear 42. The servo motor 41 drives the driving bevel gear 42 to rotate, thereby driving the driven bevel gear 43 and the threaded rod 44 to rotate. Further, the moving rod 45 drives the support plate 32 to move horizontally, and then the support plate 32 pulls the second extension plate 24 to expand and contract by rotation. At the same time, the moving rod 45 horizontally limits the support plate 32, so as to ensure that the driven wheel 31 can always contact the ground to provide a supporting force for the second extension plate 24.

[0035] Driven wheels 31 are fixed at both ends below the vehicle body 1, so as to ensure the overall balance of the vehicle body 1. Separate driving motors are provided on the driving wheels 11 on both sides of the vehicle body 1, so that the driving wheels 11 on both sides can rotate at different speeds simultaneously, and then the vehicle body 1 can complete a large-angle turn to cope with the complex terrain environment in the warehouse.

[0036] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
