[0022] 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.

[0023] Reference Figure 1 - Figure 2 This utility model provides an embodiment of an unmanned vehicle unloading conveyor belt, including an unmanned vehicle 1. The unmanned vehicle 1 serves as a mobile carrier, integrating positioning, navigation, and obstacle avoidance systems to enable autonomous transportation of goods to the unloading point. A storage box 2 is provided at the axle of the unmanned vehicle 1, providing a closed storage space for goods. The storage box 2 integrates layering, unloading, and auxiliary mechanisms, supporting quick disassembly and maintenance. A cover plate 3 is hinged to the front surface of the storage box 2, sealing the storage box 2 through the hinge structure to prevent goods from falling off during transportation. During unloading, it is opened by an electric telescopic support rod 48. A light-transmitting plate is provided at the axle of the front surface of the cover plate 3 to facilitate the entry of external light or the detection of the internal goods status by infrared sensors. An unloading assembly 4 is provided inside the storage box 2, and an auxiliary assembly 5 is provided on the lower side of the unloading assembly 4.

[0024] Reference Figure 2 - Figure 4The unloading assembly 4 includes a layered plate 41, which is fixedly installed on the rear surface of the inner wall of the storage box 2. The layered plate 41 divides the interior of the storage box 2 into upper and lower layers. The upper layer carries the storage box 45, and the lower layer accommodates the pushing mechanism. An electric telescopic rod 42 is fixedly installed on the rear surface of the inner wall of the storage box 2 near the lower side of the layered plate 41. The electric telescopic rod 42 provides horizontal thrust, driving the pushing plate 43 to push the storage box 45 out of the hatch. The pushing plate 43 is fixedly installed at the telescopic end of the electric telescopic rod 42. The pushing plate 43 slides in contact with the lower surface of the layered plate 41 and directly contacts the rear side of the storage box 45 to ensure uniform force during pushing. The upper surface of the pushing plate 43 contacts the lower surface of the layered plate 41. Slide grooves 44 are provided at both ends of the upper surface of the layered plate 41. The slide grooves 44 restrict the movement direction of the sliding plate 46 and reduce the frictional resistance when the storage box 45 is pushed out. The sliding plate 46 is slidably connected to the inner wall of the slide groove 44. The sliding plate 46 connects the storage box 45 and the slide 44, converting sliding friction into rolling friction and reducing energy consumption. The storage box 45 is fixedly installed on the upper surface of the sliding plate 46, independently carrying unit goods. The sliding plate 46 and the slide 44 cooperate to achieve quick loading and unloading. The left and right ends of the front surface of the storage box 2 are fixedly connected to the slide rails 47. The slide rails 47 provide an arc-shaped movement trajectory for the electric telescopic support rod 48, ensuring that the cover 3 opens at a preset angle. The rear surface of the cover 3 is fixedly installed with the mounting base 49. The inner wall of the mounting base 49 is hinged to the inner wall of the slide rail 47 through the electric telescopic support rod 48. One end of the electric telescopic support rod 48 is hinged to the slide rail 47, and the other end is hinged to the mounting base 49, realizing the 90°-180° rotation of the cover 3. The top 48 of the electric telescopic support rod is hinged to the inside of the mounting base 49. The mounting base 49 is fixed to the rear surface of the cover 3, allowing the electric telescopic support rod 48 to finely adjust the angle in three-dimensional space.

[0025] Reference Figure 2 - Figure 4The auxiliary component 5 includes a drawer 51, which is located on the lower surface of the inner wall of the storage box 2 and is hidden at the bottom of the storage box 2. The drawer 51 houses the auxiliary plate 55 and extends the length of the unloading platform when unfolded. Movable grooves 52 are provided on both the left and right ends of the inner wall of the drawer 51 to limit the linear movement path of the movable seat 54. A front limiting plate 53 prevents it from detaching. The front end of the movable groove 52 is fixedly connected to the limiting plate 53, which triggers a hard stop when the movable seat 54 slides to the front end, ensuring that the auxiliary plate 55 is fully unfolded. The movable seat 54 is slidably connected to the inner wall of the movable groove 52, and the movable seat 54 supports the auxiliary plate 55 through a bearing structure. It achieves a combined motion of horizontal sliding and vertical flipping. An auxiliary plate 55 is hinged inside the movable seat 54. After the auxiliary plate 55 is unfolded, it connects with the outlet of the storage box 2 to form an inclined slide, which guides the goods to slide down smoothly. Multiple sets of evenly distributed rollers 56 are opened on the upper surface of the auxiliary plate 55. The rollers 56 are evenly distributed on the surface of the auxiliary plate 55, which converts the sliding friction of the goods into rolling friction and prevents jamming. The rollers 56 are rolled in the grooves on the upper surface of the auxiliary plate 55. Handles 57 are fixedly connected to the left and right surfaces of the auxiliary plate 55. The handles 57 are used for manual gripping to manually unfold or retract the auxiliary plate 55. The surface is covered with a rubber layer to enhance grip strength.

[0026] Working principle: The unmanned vehicle 1 autonomously drives to the unloading point using its own positioning, navigation, and obstacle avoidance system. The storage box 2 is in a closed state, and the cover 3 is pressed against the box body by a hinged structure to prevent the goods from falling out. The light-transmitting plate continuously provides the status signal of the goods inside the box to the external sensors to ensure real-time monitoring by the system. After the vehicle reaches the designated coordinates, the control unit first verifies the position accuracy and then issues an opening command. One end of the electric telescopic support rod 48 is guided by the arc-shaped slide rail 47, and the other end is pulled by the mounting base 49 to flip the cover 3 backward and upward. The flipping angle can be set between 90° and 180° according to the program to avoid interference with external facilities. After the cover 3 is fully opened, the drawer 51 is unlocked, and the operator or remote command can continue to execute subsequent actions. The auxiliary plate 55 stored in the drawer 51 is in a folded state. Its left and right sides are embedded in the moving slot 52 by the moving seat 54, and the front end is mechanically limited by the limiting plate 53 to ensure that the drawer 51 will not come out as a whole when it is pulled out. The storage box 2 is divided into upper and lower layers by a layered plate 41. The upper layer is the cargo space. The storage box 45 forms a low-friction sliding pair with the sliding groove 44 on the layered plate 41 via a sliding plate 46. The control unit drives the electric telescopic rod 42 to extend, and the pusher plate 43 moves along the lower surface of the layered plate 41, pushing the storage box 45 horizontally towards the hatch. The sliding plate 46 converts sliding friction into rolling friction, reducing energy consumption and preventing jamming. When the storage box 45 is pushed to its limit position, its front end naturally rests on the auxiliary plate 55. At this time, a manual or electric mechanism uses the handle 57 to flip the folded auxiliary plate 55 downward around the moving seat 54, forming an inclined slide. The rollers 56 roll freely in the groove, further converting the sliding friction between the goods and the plate surface into rolling friction, so that the goods can smoothly slide down to the target platform or conveyor line. The limiting plate 53 ensures that the angle of the auxiliary plate 55 is fixed after it is fully extended, preventing rebound. After the goods are unloaded, the control unit drives the electric telescopic rod 42 to retract, which drives the pusher plate 43 to reset. The auxiliary plate 55 is manually or electrically retracted, folded back, and pushed into the storage box 2 with the drawer 51. The electric telescopic support rod 48 retracts, and the cover plate 3 closes with the cooperation of the slide rail 47 and the mounting base 49. The light-transmitting plate provides a locking confirmation signal again, and the unmanned vehicle 1 then enters the next round of transportation tasks.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
