[0002] A self-balancing AGV vehicle is an automatic guided vehicle that can maintain balance and usually relies on gyroscopes and accelerometers to adjust its own stability. It can automatically adjust its attitude during driving to ensure that the vehicle body does not tilt, thereby improving the driving stability and safety. This technology makes it more flexible in complex environments. However, if the goods placed on the front and rear of the vehicle are not properly placed, it will cause the center of gravity to shift. This shift will affect the balance of the vehicle, making it prone to tilt or overturn during driving, especially for vehicles relying on the self-balancing system. This will lead to unstable operation, increase the risk of overturning, and further damage the equipment or cause loss of goods. Summary of the Utility Model

[0026] As Figures 1-6 Shown in the figure, a self-balancing AGV cart proposed by the present utility model includes a frame 1, and further includes: a storage board 2 rotatably installed on the frame 1, a plurality of anti-slip ridges 4 arranged linearly are provided in the middle of the storage board 2, a pair of rotation slots 21 are opened on the storage board 2, a pair of rotation seats 14 that are snapped into the rotation slots 21 are fixedly connected to the upper surface of the frame 1, and the rotation seats 14 are rotationally connected to the rotation slots 21; a pair of weighing mechanisms are arranged on the upper surface of the frame 1 to measure the goods at the front and rear ends on the storage board 2; rolling slots 22 corresponding to the weighing mechanisms are opened on the upper surfaces at both ends of the frame 1, and rolling mechanisms for moving the goods are provided inside the rolling slots 22.
[0027] Furthermore, the weighing mechanism includes weighing scales 11 arranged on the upper surfaces at both ends of the frame 1. The principle of the weighing scales 11 is the same as that of an electronic scale. When a weight acts on the weighing scales 11, this force is sensed by a sensor (usually a strain gauge). The strain gauge will deform due to the application of the weight and change its resistance value. The resistance change of the sensor is converted into an electrical signal. Usually, a bridge circuit is used to improve the accuracy of the signal. The electrical signal is amplified and converted into a digital signal. After being calculated by a microprocessor, the digital signal is displayed on a display screen to show the weight of the object. One end of the weighing scale 11 is fixedly connected to a support tube 12, and one end of the support tube 12 is fixedly connected to a display screen 13 that does not prevent the storage board 2 from rotating and is used to display the weight of the goods directly above one end of the storage board 2. The display screen 13 is the same as the screen of an electronic scale, but it extends out.
[0028] Among them, the rolling mechanism includes a plurality of pairs of rollers 23 arranged linearly and rotatably connected in the rolling slots 22. Some of the rollers 23 rotate freely, and some of the rollers 23 rotate driven by a rack 3. Opposite ends of each pair of rollers 23 are fixedly connected to a rotating rod 25. Support seats 24 for supporting the rotation of the rotating rod 25 are provided inside the storage board 2. Opposite ends of a plurality of pairs of rotating rods 25 are fixedly connected to a clamping block 26, and opposite ends of another plurality of rotating rods 25 are fixedly connected to a gear 27. An installation slot 5 is opened inside the storage board 2, and a driving mechanism for starting the rolling mechanism is provided inside the installation slot 5.
[0029] Further, the driving mechanism includes a pair of cylinders 34 reversely installed in the installation groove 5. The piston rods of the cylinders 34 are fixedly connected with connecting plates 33 slidably connected with the installation groove 5. The ends of the connecting plates 33 far from the cylinders 34 are fixedly connected with support rods 32. Between the support seats 24 inside the rolling groove 22, racks 3 meshed with the gears 27 are provided. One end of the rack 3 close to the cylinder 34 is fixedly connected with one end of the corresponding support rod 32.
[0030] In this embodiment, when the self-balancing AGV cart needs to be used, the goods are laid flat on the placement board 2 and stacked. When the goods at one end of the placement board 2 are heavier, the placement board 2 rotates towards the heavier side through the support of the rotating seat 14. At this time, the weight of the goods is measured by the weighing scale 11 at the bottom of the placement board 2, so that the weight of the goods is displayed on the display screen 13, and it can be known where the weight of the goods on the front and rear ends of the placement board 2 is larger. After the goods are placed on the placement board 2, it is not possible to make the goods at both ends of the placement board 2 reach almost balance by adding goods. Then, check the display screens 13 at both ends of the placement board 2. Whichever display screen 13 shows a heavier weight of the goods, start the cylinder 34 on the heavier side. After the cylinder 34 is started, the piston rod pushes the connecting plate 33, and the connecting plate 33 pushes the support rod 32 and the rack 3 to move. The balls 31 provided on the rack 3 make the rack 3 slide more smoothly in the rolling groove 22. Then, since the rack 3 and the gear 27 are meshed, the gear 27 drives the rotating rod 25 to rotate through the support of the support seat 24. The end of the rotating rod 25 far from the gear 27 drives the roller 23 to rotate, so that the goods thereon move towards the anti-slip convex strips 4 through the rotation of the plurality of rollers 23. Finally, through the lever principle, until the weights of the goods displayed on the pair of display screens 13 are not much different, the center of gravity of the placement board 2 can be at the central position of both ends of the vehicle frame 1, thus avoiding tilting or overturning caused by the offset of the center of gravity.
[0031] The preferred embodiments of the above utility model are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only the specific embodiments. Obviously, according to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments to better explain the principle and practical application of the utility model, so that those skilled in the relevant technical field can understand and utilize the utility model well. The utility model is only limited by the claims and their full scope and equivalents.
