[0001] The application relates to the technical field of unmanned vehicle devices, in particular to an AGV unmanned vehicle with an automatic navigation system. BACKGROUND

[0002] AGV is an automatic guided vehicle, which is equipped with an automatic guiding device such as an electromagnet or an optical device, can travel along a specified guiding path, has safety protection and various transfer functions, is an industrial application without a driver, uses a rechargeable battery as a power source, and can control the travel route and behavior of the vehicle through a computer or use an electromagnetic track to set the travel route. The electromagnetic track is attached to the floor, and the unmanned carrier follows the information brought by the electromagnetic track to move and act. AGV is characterized by wheel movement, has the advantages of fast movement, high work efficiency, simple structure, strong controllability, good safety, etc. Compared with other devices commonly used in material conveying, AGV does not need to lay tracks, supports and other fixed devices in the activity area, and is not limited by the site, road and space. Therefore, in the automatic logistics system, it can fully realize its automation and flexibility, realize efficient, economic and flexible unmanned production, and has high automation. The computer, electric control device, laser reflection plate and the like are controlled. When a certain link in the workshop needs auxiliary materials, the staff inputs relevant information to the computer terminal, the computer terminal sends the information to the central control room, and the professional technicians issue instructions to the computer. Under the cooperation of the electric control device, the instruction is finally accepted and executed by AGV to send the auxiliary materials to the corresponding place.

[0003] For example, the patent document with the announcement number CN 112147999 B discloses an automatic driving experiment AGV vehicle platform, which perceives the changes of complex traffic environment by an environment perception system, realizes accurate positioning by a positioning and navigation system, provides movable network data by a router, carries out various calculations for real vehicle control and vehicle data transmission and reception by a control decision system relying on an industrial computer as a core processor, mainly plans a path in an electronic map by a path planning system, inputs instructions of the industrial computer and provides a visual operation interface by a man-machine interaction system, realizes real-time data transmission of the vehicle by a data transmission bus, and controls the motion control of the AGV electric vehicle chassis by a motion control system relying on the AGV electric vehicle chassis. An artificial takeover system is also designed, which is a remote controller and has the highest control authority, and realizes one-key takeover of the AGV electric vehicle chassis in an emergency. The application is a low-cost, multi-functional and multi-platform automatic driving experiment AGV vehicle platform.

[0004] However, the structure cannot protect the core element structure of the device from the outside of the vehicle body during actual automatic navigation transportation operation. Once the AGV vehicle body is suddenly impacted by the surrounding, the core radar element of the device is easily affected by external force and cannot be buffered, but is transmitted to the radar surface, causing the whole to shake, which is harmful to the radar itself. Serious impact force can even cause the radar to stop running on the spot and need immediate repair, resulting in high subsequent maintenance cost. After the device is impacted, the whole vehicle body may still slip and translate due to the good instantaneous locking structure, causing secondary damage to the vehicle body, which is not conducive to daily use. Therefore, an AGV unmanned vehicle with an automatic navigation system is urgently needed to solve the above problems. SUMMARY

[0030] The front nose seat 15 is fixedly connected with one end of the AGV unmanned vehicle body 1, and the driving frame 16 is fixedly connected with the other end of the AGV unmanned vehicle body 1. The front nose seat 15 is fixedly connected with a protective front frame 17 away from one end of the AGV unmanned vehicle body 1. The inside of the protective front frame 17 is provided with a first retractable frame 18. The front of the first retractable frame 18 is provided with a first exhaust groove 19. The back of the first retractable frame 18 is provided with a first folding air bag 20. The back of the first folding air bag 20 is provided with a first air inlet valve 21. The driving frame 16 is fixedly connected with a protective rear frame 22 away from one end of the AGV unmanned vehicle body 1. The protective rear frame 22 is the same structure as the protective front frame 17. The driving frame 16 is fixedly connected with a mounting wheel frame 23 on both sides. The inside of the mounting wheel frame 23 is provided with a driving wheel 24. The end of the driving frame 16 close to the AGV unmanned vehicle body 1 is provided with a heat dissipation mesh groove 25. The end of the protective rear frame 22 close to the driving frame 16 is provided with a first monitoring outer valve 26. The end of the front nose seat 15 close to the AGV unmanned vehicle body 1 is provided with a controller 27. The front nose seat 15 is provided with a steering wheel 28 on both sides. The protective front frame 17 is fixedly connected with a buckle plate 29 on both ends. The first retractable frame 18 is fixedly connected with a buckle strip 30 on both ends.

The inside of the protective side frame 14 is provided with a second monitoring outer valve 42. The inside of the protective front frame 17 is provided with a third monitoring outer valve 43. Once the AGV unmanned vehicle body 1 moves forward and encounters an emergency collision problem, the first retractable frame 18 can be compressed into the protective front frame 17. When the third monitoring outer valve 43 of the protective front frame 17 detects air pressure backflow, the device will start all air suction pumps 4 at the same time, so that the air extraction operation at the air distribution frame 2 is carried out with full force, the air pressure is instantly boosted to the strongest, and then under the action of the relatively strong air pressure, the connection between the buckle plate 29 and the buckle strip 30 is broken, the first air inlet valve 21 in the first retractable frame 18 is expanded, thereby fully covering the front nose seat 15 of the AGV unmanned vehicle body 1, and effectively buffering and protecting. The protective rear frame 22 with the same structure and the protective side frame 14 with similar structure are expanded and protected under the impact of strong air pressure.

[0031] Working principle: in use, the user first starts the AGV unmanned vehicle body 1 as a whole, so that it moves and transports automatically. At this time, the air suction pump 4 in the pump rack 3 on the side of the air distribution rack 2 is started in turn, so that it slowly and evenly sucks air from the air collection frame 5. Then the air flow sucked into the air collection frame 5 is quickly transported to four directions of the AGV unmanned vehicle body 1 through the air distribution rack 2. With the assistance of the first communication pipe 40 and the second communication pipe 41, the air flow evenly enters the protection front frame 17 and the protection rear frame 22 at both ends of the AGV unmanned vehicle body 1 and the protection side frame 14 on both sides. The first contraction frame 18 and the second contraction frame 36 are in a slightly inflated state. At this time, the air flow is evenly discharged from the first air exhaust groove 19 at both ends of the first contraction frame 18 and the second air exhaust groove 38 at both ends of the second contraction frame 36, ensuring effective protection of the AGV unmanned vehicle body 1 around during daily use. If the AGV unmanned vehicle body 1 collides in the process of moving forward, the first contraction frame 18 can first be compressed into the protection front frame 17. When the third monitoring outer valve 43 of the protection front frame 17 detects air pressure backflow, the equipment will start all air suction pumps 4 at the same time to perform strong air extraction at the air distribution rack 2, so that the air pressure is instantly increased to the strongest. Then under the action of strong air pressure, the connection between the buckle plate 29 and the buckle strip 30 is broken, the first air inlet valve 21 in the first contraction frame 18 is expanded, and the front nose seat 15 of the AGV unmanned vehicle body 1 is fully covered, thereby effectively buffering and protecting. The protection rear frame 22 and the protection side frame 14 with similar structure design are also expanded and protected under the impact of strong air pressure, so that the entire protection structure is a whole design, which can quickly and comprehensively protect the surrounding position of the AGV unmanned vehicle body 1, so that the AGV unmanned vehicle body 1 remains stable after collision, thereby quickly and stably protecting the battery pack 11 and the millimeter wave radar 12 on the surface of the AGV unmanned vehicle body 1. During daily use, the air suction pump 4 can perform uniform air suction, the air collection frame 5 can generate efficient and continuous heat dissipation airflow, the heat generated by the laser radar 8, the display 9, the battery pack 11 and the millimeter wave radar 12 can be quickly sucked into the air collection frame 5, and the heat in the driving frame 16 can also be continuously discharged from the heat dissipation mesh 25 to the air collection frame 5, and then stably enter the protection side frame 14 or the protection front frame 17 through the air distribution rack 2 and the first communication pipe 40 and the second communication pipe 41. According to the thermal expansion and contraction of the air flow, the air flow with heat can better provide the inflation of the first folding air bag 20 and the second folding air bag 37 with sufficient power, thereby stably dissipating heat and improving the protection effect when the first folding air bag 20 and the second folding air bag 37 are ejected. When the second communication pipe 41 is filled with strong air flow,The air resistance valve 34 on both sides of the second communication pipe 41 can be opened by the air flow, so that the air flow quickly enters the solid wheel frame 13 along the conveying pipe 33, at this time, the pipe-shaped air bag 32 in the solid wheel frame 13 is quickly filled with air flow, under the limiting of the limiting rubber frame 31, the pipe-shaped air bag 32 quickly performs the wrapping operation on the wheel surface of the steering wheel 28 and the driving wheel 24, the equipment is quickly lifted as a whole, and secondary injury caused by the sliding of the equipment is avoided, and the above is the whole working principle of the application.

[0032] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments, but that the application can be implemented in other concrete forms without departing from the spirit or the essential characteristics thereof. The embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and it is intended that all changes and modifications which come within the meaning and range of equivalency of the elements recited in the claims are to be embraced by the application.
