Technical Field
[0001] The utility model relates to the technical field of automatic guided vehicles, in particular to an AGV automatic guided vehicle convenient for energy replenishment. Background Art
[0002] AGV, the full name is Automatic Guided Vehicle, is a highly automated handling robot. Its core lies in being equipped with advanced automatic guiding devices such as electromagnetic and optoelectronic ones. Such robots can accurately and errorlessly drive autonomously along the preset guiding path. AGV is famous for its high automation, excellent safety performance and flexible operation characteristics. It can seamlessly connect the material transfer between production lines or between the production line and the warehouse, greatly reducing the labor burden and significantly shortening the operation time. It is a powerful assistant for improving production efficiency and reducing costs.
[0003] However, for the existing AGV carts at present, due to the fixed design of the platform for loading goods, this greatly limits their working range. When it is necessary to carry goods at a relatively high position, the carts often cannot work. Similarly, it is also difficult for the carts to transport goods to a high place. This limitation not only restricts the flexibility of the carts' use but also directly leads to a decrease in the overall transportation efficiency.
[0004] Therefore, aiming at the situation that the platform for loading goods in the above-mentioned AGV carts is often fixed, resulting in a reduction in the efficiency of goods transportation, an AGV automatic guided vehicle convenient for energy replenishment can be designed. Through a scissor lift structure and a belt conveyor structure, while flexibly lifting the loading platform in the AGV cart, the efficiency of goods transportation is improved. Summary of the Utility Model
[0005] In order to overcome the problem that the platform for loading goods in the AGV cart is often fixed, resulting in a reduction in the efficiency of goods transportation.
[0006] The technical solution of the utility model is: an AGV automatic guided vehicle convenient for energy replenishment, including a cart, universal wheels, a charging interface, a through groove, a lifting module and a transportation module; four universal wheels with built-in self-locking structures are installed at the lower end of the cart, a charging interface for quickly charging the cart is installed at the right end of the cart, a slope is arranged at the right end of the cart and is located above the charging interface, a display screen is arranged at the upper end of the slope, a through groove is opened at the upper end of the cart, the lifting module is installed in the through groove, a sliding structure and a hinged structure are arranged in the lifting module, the transportation module is installed at the upper end of the lifting module, and a belt conveyor structure is arranged in the transportation module.
[0007] Preferably, the trolley is the main moving platform of the entire AGV (Automated Guided Vehicle). The omnidirectional wheels at its lower end not only provide the moving ability but also have a built-in self-locking structure to ensure that the trolley can be stably parked at the designated position when stationary, preventing accidental movement. The charging interface provides fast charging service for the trolley, facilitating energy replenishment. The display screen is used to display the status information of the trolley, such as battery level, working mode, and operation prompts. The lifting module realizes the lifting function through the built-in sliding structure and hinged structure, enabling the transportation module to move up and down to adjust the height of the goods, thus solving the problem of handling goods at high places. The transportation module is used to carry and transport goods, and its built-in belt conveyor structure can automatically convey the goods from one end to the other end, improving the transportation efficiency.
[0008] Preferably, the lifting module includes a hydraulic strut and a first hinge seat; the first hinge seat is fixedly connected to the bottom of the through groove, and the lower end of the hydraulic strut is rotatably connected within the first hinge seat. The hydraulic strut serves as the power source of the lifting module and drives the lifting of the lifting module through its telescopic movement. The hydraulic strut has the advantages of large force, good stability, and precise control, and is suitable for occasions that require a large lifting force and stability. The first hinge seat, as the rotational connection point at the lower end of the hydraulic strut, allows the hydraulic strut to rotate freely within it while maintaining a firm connection with the bottom of the through groove, ensuring the stability of the lifting process.
[0009] Preferably, the lifting module further includes slide rails, chutes, sliders, and second hinge seats; there are two slide rails that are symmetrically fixed to the bottom of the through groove front and back. Each slide rail is provided with a chute inside. There are two second hinge seats, and both ends of each second hinge seat are fixedly connected with sliders adapted to the chutes. The second hinge seats are slidably connected to the chutes through the sliders. The slide rails and chutes provide guidance and support for the lifting module. The chutes are opened inside the slide rails to guide the sliding of the sliders, ensuring that the lifting module can work smoothly during the lifting process. The sliding of the sliders in the chutes enables the second hinge seats to move horizontally along the slide rails.
[0010] Preferably, the lifting module further includes a third hinge seat, a cargo hold, a fourth hinge seat, and hinge rods. There are two third hinge seats, which are symmetrically fixed to the right side of the bottom of the through groove front and back.

The lower ends of each group of hinge rods are rotatably connected to the corresponding third hinge seats, and the upper ends of each group of hinge rods are rotatably connected to the corresponding fourth hinge seats. A connecting plate is fixedly connected between the two groups of hinge rods. One end of the connecting plate is connected to the telescopic end of the hydraulic strut. The third hinge seat serves as the rotational connection point for the lower end of the hinge rod, allowing the hinge rod to freely rotate inside it. The cargo hold is used to carry and transport goods. The fourth hinge seat serves as the rotational connection point for the upper end of the hinge rod. The hinge rods enable the cargo hold to maintain a relatively stable posture during the lifting process, avoiding tilting or shaking. A connecting plate is fixedly connected between the two groups of hinge rods, thereby converting the telescopic movement of the hydraulic strut into the lifting movement of the cargo hold.
[0011] Preferably, the transportation module includes a placement groove and a first rotary support seat. The upper end of the cargo hold is provided with a placement groove for accommodating goods. The right inner wall of the placement groove is fixedly connected with a first rotary support seat. The placement groove is used to accommodate and transport goods. The first rotary support seat serves as the rotational connection point for the right end of the driving transmission roller to ensure the stability of the driving transmission roller during rotation.
[0012] Preferably, the transportation module further includes a driving transmission roller, a rotary motor, and a coupling. The right end of the driving transmission roller is rotatably connected to the first rotary support seat. The left end of the driving transmission roller extends leftward to the left end of the cargo hold. A coupling is installed at the left end of the driving transmission roller and is connected to the output shaft of the rotary motor through the coupling. The driving transmission roller is the power transmission component of the transportation module. The rotary motor provides the power source for the transportation module. The coupling is used to connect the output shaft of the rotary motor and the left end of the driving transmission roller to achieve power transmission, ensuring that the rotary motor can stably drive the driving transmission roller to rotate.
[0013] Preferably, the transportation module further includes four second rotary support seats, a driven transmission roller, an auxiliary transmission roller, and a conveyor belt. The four second rotary support seats are respectively fixedly connected to the left and right inner walls of the placement groove. The left and right ends of the driven transmission roller are rotatably connected to two of the second rotary support seats. The left and right ends of the auxiliary transmission roller are rotatably connected to the other two second rotary support seats. The driving transmission roller, the driven transmission roller, and the auxiliary transmission roller are all commonly rotatably connected with the conveyor belt. The second rotary support seats provide rotational support for the driven transmission roller and the auxiliary transmission roller. The driven transmission roller and the driving transmission roller jointly support and drive the conveyor belt for transmission. The auxiliary transmission roller is used to support the conveyor belt and adjust its tension. The conveyor belt is wound around the driving transmission roller, the driven transmission roller, and the auxiliary transmission roller to form a closed-loop structure, thereby facilitating the transportation of goods.
[0014] The beneficial effects of the present utility model:
[0015] 1. Through the coordinated work of the lifting module and the transportation module, the height of the cargo hold can be flexibly adjusted, enabling the goods to be precisely lifted to the required height. This not only facilitates the transportation of goods to high places but also effectively transports the goods from high places to low places. In addition, the transportation module uses a belt transmission structure to ensure that the goods move smoothly and efficiently in the horizontal direction to the designated position, thus realizing the rapid loading and unloading of goods and greatly improving the flexibility and efficiency of goods transportation.
[0016] 2. The articulated rods enable the cargo hold to maintain a relatively stable posture during the lifting process, avoiding tilting or shaking. In addition, the connecting plate between the two groups of articulated rods converts the telescopic movement of the hydraulic strut into the lifting movement of the cargo hold.

[0028] Embodiment 1:
[0029] When it is necessary to lift goods from a lower position to a higher position, utilize the extension function of the hydraulic strut 501 to drive the articulated rod 510 to generate a rotational movement. This rotational action drives the second articulated seat 506 to smoothly slide along the chute 504 built in the slide rail 503. Through the coordinated action of the third articulated seat 507 and the fourth articulated seat 509, the cargo hold 508 is smoothly lifted.

[0030] Embodiment 2:
[0031] When it is necessary to transport goods from a high place to a low place, operate the hydraulic strut 501 to contract, which also causes the rotation of the articulated rod 510, and then pushes the second articulated seat 506 to move along the chute 504 in the slide rail 503. During this process, the third articulated seat 507 and the fourth articulated seat 509 cooperate closely again, so that the cargo hold 508 can descend smoothly. At the same time, the rotation motor 604 is activated to drive the active transmission roller 603 to rotate, which acts together with the driven transmission roller 607 and the auxiliary transmission roller 608 to make the conveyor belt 609 operate, so as to safely and smoothly transport the goods to the target location at the low place.
[0032] Through the above steps, through the coordinated work of the lifting module and the transportation module, the height of the cargo hold 508 can be flexibly adjusted, so that the goods can be accurately lifted to the required height. This not only facilitates the transportation of goods to high places, but also effectively transports the goods at high places to low places. In addition, the transportation module uses a belt transmission structure to ensure that the goods move smoothly and efficiently in the horizontal direction to the designated position, thus realizing the rapid loading and unloading of goods, greatly improving the flexibility and efficiency of goods transportation, and solving the problem that the loading platform in the AGV cart is often fixed, resulting in a reduction in the efficiency of goods transportation.
