[0002] AGVs, or Automated Guided Vehicles, are transport vehicles equipped with electromagnetic, optical, or vision-based automatic guidance devices. They can travel along a prescribed path and have safety protection and various transfer functions. They do not require manual driving and can autonomously complete path planning, start-stop, and turning actions through preset programs or control systems. They can also flexibly adjust their operating routes according to the needs of different scenarios to adapt to different working environments.

[0003] Currently, a loading mechanism for an AGV (Automated Guided Vehicle) with patent publication number CN219601434U discloses a frame, a drive unit, and two extension components. The frame has first grooves on both sides, and the drive unit is installed below the frame. The two extension components are symmetrically arranged on both sides of the frame. Each extension component includes an extension plate, a first rotating plate, a second rotating plate, and a limiting unit. One end of the extension plate has a first threaded hole, and one side of the extension plate is rotatably connected to one side of the frame. The two ends of the first rotating plate are rotatably connected to the lower part of the extension plate and one end of the second rotating plate, respectively.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] Please see Figures 1-3 This is the first embodiment of the present invention, which provides an AGV (Automated Guided Vehicle) telescopic loading structure, including...

[0025] The frame 1 has symmetrically distributed second sliding grooves 14 on its side surface. The second sliding grooves 14 provide a guide track for the sliding of the extension plate 3. With the sliding connection between the extension plate 3 and the second sliding groove 14, the extension plate 3 can be guaranteed to move smoothly along a fixed direction during the extension and retraction process, avoiding deviation or jamming, ensuring the stability and reliability of the extension plate 3 when it is extended or retracted, and thus ensuring the normal operation of the entire loading structure.

[0026] There are two expansion plates 3, and the two expansion plates 3 are slidably connected to the two second slide rails 14. The design of the two expansion plates 3 can be symmetrically unfolded to both sides, which effectively increases the loading area of ​​the AGV and can adapt to loading goods of different sizes and shapes, improving the versatility and practicality of the AGV. Through the sliding cooperation with the second slide rails 14, the extension and retraction operation of the expansion plates 3 is convenient and can be flexibly adjusted according to the actual loading needs. When not in use, they can be retracted to save space and facilitate the AGV to travel in narrow passages or spaces.

[0027] The adjustment support component includes a vertical plate 6 installed at the bottom center of the frame 1, and first electric cylinders 61 symmetrically arranged on the side surface of the vertical plate 6. The output end of the first electric cylinder 61 is connected to a movable box 5. The vertical plate 6 serves as the mounting base for the first electric cylinder 61, providing stable support and ensuring the stability of the first electric cylinder 61 during operation. This allows it to reliably drive the movable box 5 to move. The movable box 5 not only protects the second electric cylinder 7 from external impacts and dust but also provides it with installation space, facilitating the overall mounting of the frame. The inner bottom of the movable box 5 is equipped with a second electric cylinder 7, and the output shaft of the second electric cylinder 7 passes through the movable box 5 and is connected to a push plate 71 that can abut against the extension plate 3. When the extension plate 3 is extended, the second electric cylinder 7 drives the push plate 71 to move upward and abut against the bottom surface of the extension plate 3, providing additional support for the extension plate 3, effectively enhancing the load-bearing capacity of the extension plate 3, improving the strength of the extension plate 3, preventing the extension plate 3 from deforming or being damaged when carrying goods, extending the service life of the extension plate 3, and also improving the stability and safety of goods transportation.

[0028] In this embodiment, preferably, a sliding plate 53 is also provided at the bottom of the mobile box 5, and a first sliding groove 13 is opened in the bottom of the frame 1 for the sliding plate 53 to slide. The cooperation between the sliding plate 53 and the first sliding groove 13 provides smooth sliding guidance for the movement of the mobile box 5 in the frame 1, reduces the friction when the mobile box 5 moves, makes it easier and less strenuous for the first electric cylinder 61 to drive the mobile box 5 to move, and at the same time ensures the stability and accuracy of the movement of the mobile box 5, and ensures that the push plate 71 can accurately abut against the corresponding position on the bottom surface of the extension plate 3.

[0029] In this embodiment, preferably, a heat dissipation vent 51 is also provided on the mobile housing 5. The heat dissipation vent 51 allows the heat generated by the second electric cylinder 7 inside the mobile housing 5 during operation to be dissipated in a timely manner, preventing the component temperature from becoming too high due to heat accumulation, which would affect its performance and service life. This ensures that the second electric cylinder 7 can work stably in a suitable temperature environment. The dustproof net 510 set inside the heat dissipation vent 51 not only ensures the heat dissipation effect but also effectively blocks external dust and debris from entering the mobile housing 5, preventing dust from affecting the normal operation of the second electric cylinder 7 and preventing wear, jamming, and other problems caused by dust accumulation. This plays a protective role and improves the reliability and stability of the equipment.

[0030] In this embodiment, preferably, one end of the mobile box 5 is open. The opening design facilitates the installation, debugging, maintenance and repair of the second electric cylinder 7 inside the mobile box 5. One end of the mobile box 5 is hinged with a protective door 52. The protective door 52 can be closed when not in use to protect the internal components and prevent external factors from affecting the internal components. When it is necessary to operate the internal parts, it can be opened easily, making operation convenient and improving the convenience and efficiency of equipment maintenance.

[0031] In this embodiment, preferably, it also includes a connecting port 12 opened on the frame 1 and a limiting plate 4 disposed on the extension plate 3. The limiting plate 4 can slide within the connecting port 12. The connecting port 12 provides a channel for the sliding of the limiting plate 4. The limiting plate 4 cooperates with the connecting port 12 to limit and guide the movement of the extension plate 3 during the outward pulling process, further ensuring that the extension plate 3 moves in the correct direction. At the same time, it enhances the stability of the connection between the extension plate 3 and the frame 1, prevents the extension plate 3 from shaking or detaching, and ensures the safety and reliability of the operation of the extension plate 3.

[0032] In this embodiment, preferably, a controller 11 is installed on the front surface of the frame 1. The first electric cylinder 61 and the second electric cylinder 7 are both electrically connected to the controller 11. As the control core of the entire adjustment support component, the controller 11 can accurately control the actions of the first electric cylinder 61 and the second electric cylinder 7, realize automated control, and improve the convenience and accuracy of operation. At the same time, centralized control facilitates unified management and monitoring of the equipment, and improves the intelligence level and work efficiency of the equipment.

[0033] In this embodiment, preferably, a maintenance port is provided at the front end of the frame 1, and a maintenance plate 2 is detachably installed on the front end of the frame 1 outside the maintenance port. The maintenance port provides a maintenance channel for components such as the first electric cylinder 61 and the moving box 5 inside the frame 1. When these components malfunction or require maintenance, the internal components can be easily inspected, repaired, and replaced by disassembling the maintenance plate 2, which reduces the difficulty and cost of equipment maintenance and improves the maintainability of the equipment. The detachable maintenance plate 2 can close the maintenance port when not in use to protect the internal components from external influences. The maintenance plate 2 of this application is fixed to the frame 1 with screws, which increases the firmness of the maintenance plate 2. Example

[0034] Please see Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0035] A support plate 8 is installed at the front end of the frame 1, and the top of the support plate 8 has a socket 81. The bottom of the maintenance plate 2 is provided with a strip 21 that matches the socket 81. The support plate 8 provides the mounting base and support for the maintenance plate 2. The cooperation between the socket 81 and the strip 21 makes the installation and disassembly of the maintenance plate 2 more convenient and quick. During installation, simply insert the strip 21 into the socket 81 to complete the initial fixation of the maintenance plate 2, and then further fix it with screws to ensure that the maintenance plate 2 is firmly installed. During disassembly, the operation is reversed. This structural design improves the efficiency of the installation and disassembly of the maintenance plate 2 and facilitates the daily maintenance and repair of the equipment.

[0036] The working principle and usage process of this utility model: According to the size of the goods, if it is necessary to expand the loading area, input the command on the controller 11 to start the first electric cylinder 61. The first electric cylinder 61 extends and retracts, causing the sliding plate 53 at the bottom of the mobile box 5 to slide in the first sliding groove 13 at the bottom of the frame 1, moving the mobile box 5 to a suitable position, so that the second electric cylinder 7 and the push plate 71 inside the mobile box 5 are in a position that can provide support for the extension plate 3.

[0037] Manually pull the extension plate 3, and use the sliding connection between the extension plate 3 and the second slide groove 14 on the side surface of the frame 1 to pull the two extension plates 3 out symmetrically to both sides. During this process, the limiting plate 4 on the extension plate 3 slides in the connecting port 12 on the frame 1, which plays a limiting and guiding role in the movement of the extension plate 3, ensuring that the extension plate 3 extends out smoothly.

[0038] After the extension plate 3 is fully extended, the second electric cylinder 7 is activated again by the controller 11. The second electric cylinder 7 pushes the push plate 71 upward until the push plate 71 abuts against the bottom surface of the extension plate 3, providing additional support for the extension plate 3 and enhancing the load-bearing capacity of the extension plate 3.

[0039] Place the goods stably on the loading surface consisting of the frame 1 and the extension plate 3 to ensure that the goods are evenly and stably placed and to avoid the center of gravity shifting, which would affect transportation safety.

[0040] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
