Description

Technical Field

[0001] This utility model belongs to the field of AGV (Automated Guided Vehicle) vehicles, specifically, it relates to an AGV trackless shuttle vehicle. Background Technology

[0002] Trackless AGVs, also known as unmanned transport vehicles, automated guided vehicles, or laser-guided vehicles, are characterized by being driverless. Equipped with an automatic guidance system, AGVs can automatically travel along a predetermined route without human guidance, transporting goods or materials from the starting point to the destination. Another feature of AGVs is their flexibility, high degree of automation, and high level of intelligence, making them highly versatile.

[0003] Traditional AGV trackless shuttles have limited obstacle avoidance speed and processing capacity when faced with suddenly appearing dynamic obstacles, which may cause sudden stops and path blockages, causing the AGV trackless shuttle to tilt forward or backward, or even pose a collision risk.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an AGV trackless shuttle vehicle.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An AGV trackless shuttle includes an AGV support plate, with rollers on both sides and anti-slip and shock-absorbing pads. The AGV support plate has an internal placement slot containing two gyroscopes and sensors. LiDAR sensors are installed on both sides of the AGV support plate. T-shaped grooves are formed on both sides of the AGV support plate, with toothed plates and baffles slidingly fitted inside the T-shaped grooves. One side of the toothed plate is connected to one side of the baffle, and multiple Y-shaped top posts are installed on the other side of the baffle. Soft rubber pads are installed at the ends of the Y-shaped top posts. A drive unit is provided in the placement slot, with its output end extending through the bottom of the inner wall of the placement slot into the T-shaped groove. The drive unit cooperates with the toothed plate. Support components are slidably fitted on both sides of the AGV support plate.

[0008] Optionally, battery slots are provided on both sides of the AGV support plate, and batteries are installed inside the battery slots. A hidden handle is provided on one side of the battery.

[0009] Optionally, the drive unit includes a motor installed inside the placement slot. The bottom of the inner wall of the placement slot has a first through slot that communicates with the T-shaped slide. The output end of the motor is located in the first through slot and extends into the T-shaped slide. The output end of the motor is equipped with a gear that meshes with a gear plate.

[0010] Optionally, the support assembly includes limiting grooves on both sides of the AGV support plate, with a top plate slidably fitted inside each limiting groove. Two grooves are formed on one side of the inner wall of the limiting groove, and an electric telescopic rod is installed on one side of the inner wall of each groove. A movable frame is slidably fitted inside the groove, with one side of the movable frame connected to the telescopic end of the electric telescopic rod and the other side of the movable frame connected to one side of the top plate. A guide groove is formed on one side of the inner wall of the limiting groove, and an expansion plate is installed on one side of the top plate, with the expansion plate slidably fitted inside the guide groove.

[0011] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0012] The anti-slip and shock-absorbing pads on the support plate effectively increase the friction between the goods and the carrier. At the same time, the shock absorption effect buffers the vibration caused by uneven road surfaces or sudden stops and starts. It is especially suitable for transporting precision instruments, fragile items and other goods with high stability requirements. The drive unit drives the toothed plate and baffle to slide along the T-shaped slide and the soft rubber pad to provide support and stability to prevent the AGV support plate from tilting due to sudden braking. The lidar on both sides can scan the surrounding environment in real time. Combined with the internal sensors, it can realize real-time path planning, obstacle recognition and avoidance, avoid collisions with walls, equipment or other objects, and improve the safety of trackless operation. The two gyroscopes can monitor the tilt angle and running posture of the AGV in real time. With the help of the control system, the speed or direction of the rollers can be adjusted in time, thereby realizing and improving the stability of the AGV support plate.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Please see Figure 1-4 As shown, this embodiment provides an AGV trackless shuttle vehicle, including an AGV support plate 1. Rollers 3 are provided on both sides of the AGV support plate 1. Anti-slip and shock-absorbing pads 2 are installed on the AGV support plate 1. A placement groove 8 is opened inside the AGV support plate 1. Two gyroscopes 9 are installed inside the placement groove 8. A sensor 6 is installed inside the placement groove 8. A lidar 23 is provided on both sides of the AGV support plate 1. A T-shaped slide groove 25 is opened on both sides of the AGV support plate 1. A toothed plate 12 and a baffle 13 are slidably fitted inside the T-shaped slide groove 25. One side of the toothed plate 12 is connected to one side of the baffle 13. A plurality of Y-shaped top columns 14 are installed on the other side of the baffle 13. Soft rubber pads are installed at the ends of the Y-shaped top columns 14. A drive unit is provided in the placement groove 8. The output end of the drive unit extends through the bottom of the inner wall of the placement groove 8 into the T-shaped slide groove 25. The drive unit cooperates with the toothed plate 12. Support components are slidably fitted on both sides of the AGV support plate 1.

[0024] One application of this embodiment is as follows: The rollers 3 on both sides of the AGV support plate 1 serve as moving actuators, powered by built-in drive motors 10. Due to its trackless design, it does not rely on fixed tracks. Instead, dual gyroscopes 9 monitor the vehicle's running posture in real time and transmit the data to the control system. Meanwhile, the sensors 6 in the placement slot 8 scan the surrounding environment in real time using lidar 23 to detect obstacles or cargo positions, feeding signals back to the control system to trigger deceleration, stopping, or detour commands, ensuring operational safety. When cargo is placed on the anti-slip and shock-absorbing pads 2 of the AGV support plate 1, the sensors 6 detect that the cargo has been placed in position and send a signal to the control system, enabling it to... The roller 3 moves the goods on the AGV support plate 1 to the corresponding position. However, when an obstacle is encountered and a sudden stop occurs, the dual gyroscopes 9 will collect the tilt angle or tilt speed and acceleration data of the AGV in real time. The control system will immediately trigger an emergency stop. At the same time, the gyroscopes 9 will quickly transmit the abnormal signal to the control system, which will then transmit it to the drive unit. The drive unit will then start, and its output end will mesh with the toothed plate 12 in the T-shaped slide 25, causing the toothed plate 12 to slide along the T-shaped slide 25. This will then cause the multiple Y-shaped top columns 14 on the other side of the baffle 13 to move synchronously with the baffle. Finally, the soft rubber pads at the ends will contact the ground and provide support, thereby achieving and improving the stability of the AGV support plate 1.

[0025] In this embodiment, battery slots 22 are provided on both sides of the AGV support plate 1. A battery 4 is movably installed inside the battery slot 22, and a hidden handle is provided on one side of the battery 4.

[0026] The battery slots 22 on both sides of the AGV support plate 1 are used to install the battery 4, which provides power support for the operation of the entire vehicle, including the motor 10 that drives the roller 3, the lidar 23, the gyroscope 9, the sensor 6, and the drive unit. The invisible handle on one side of the battery 4 provides convenient operation for the installation and replacement of the battery 4.

[0027] The drive unit of this embodiment includes a motor 10 installed inside the placement groove 8. The bottom of the inner wall of the placement groove 8 has a first through groove 24 that communicates with the T-shaped slide groove 25. The output end of the motor 10 is located in the first through groove 24 and extends into the T-shaped slide groove 25. The output end of the motor 10 is equipped with a gear 11, which meshes with the gear plate 12.

[0028] The output end of the motor 10 and the gear 11 extend through the first through groove 24 into the T-shaped slide groove 25, so that the gear 11 and the teeth of the tooth plate 12 are precisely meshed. When the gear 11 rotates with the output end of the motor 10, the gear 11 rotates clockwise or counterclockwise, and the teeth meshing drives the tooth plate 12 to move laterally in a straight line along the T-shaped slide groove 25. The structure of the T-shaped slide groove 25 plays a strict guiding role for the movement of the tooth plate 12, ensuring that it can only slide stably in the horizontal direction, and avoiding the gear 11 from deviating or jamming due to force when meshing with the tooth plate 12. At the same time, as the tooth plate 12 slides, the Y-shaped top column 14 moves outward and contacts the ground, ensuring the overall stability.

[0029] The support assembly of this embodiment includes limiting grooves 15 on both sides of the AGV support plate 1. A top plate 19 is slidably fitted inside each limiting groove 15. Two grooves 16 are formed on one side of the inner wall of the limiting groove 15. An electric telescopic rod 17 is installed on one side of the inner wall of the groove 16. A movable frame 18 is slidably fitted inside the groove 16. One side of the movable frame 18 is connected to the telescopic end of the electric telescopic rod 17, and the other side of the movable frame 18 is connected to one side of the top plate 19. A guide groove 21 is formed on one side of the inner wall of the limiting groove 15. An expansion plate 20 is installed on one side of the top plate 19. The expansion plate 20 is slidably fitted inside the guide groove 21.

[0030] After receiving the control signal, the electric telescopic rod 17 in the groove 16 on the inner wall of the limiting groove 15 pushes the movable frame 18 connected to it to move linearly along the groove 16 to extend or retract. The other side of the movable frame 18 is fixedly connected to the top plate 19. Therefore, the top plate 19 moves synchronously with the movable frame 18. At the same time, the expansion plate 20 can slide and extend in the guide groove 21 to increase the effective support width of the top plate 19 and adapt to goods of different sizes.
