Description

Technical Field

[0001] This utility model relates to the technical field of IGV vehicle body structure, and in particular to an IGV vehicle body structure with multi-level safety protection devices. Background Technology

[0002] With the development of intelligent manufacturing and logistics automation, Intelligent Guided Vehicles (IGVs) are widely used in complex environments such as warehouses, factories, and hospitals to undertake tasks such as material handling and path navigation. In actual operation, IGVs frequently need to navigate through narrow, densely populated, or equipment-rich areas, operating in complex and ever-changing environments. They are susceptible to external collisions, falls, or other unexpected situations, thus placing higher demands on the safety of their vehicle structure.

[0003] Most existing IGV (Indoor Gas Vehicle) body structures use a simple metal frame with outer shell panels, lacking an effective multi-stage buffer structure. This makes it difficult to absorb impact energy during a collision, leading to body damage, internal component deformation, and even system failure. Furthermore, many vehicles lack integrated real-time collision detection and alarm devices, failing to respond immediately and increasing safety hazards. In addition, the lack of effective fall prevention mechanisms when operating on elevated platforms or in multi-story warehouses can also lead to serious accidents.

[0004] In view of this, the inventors have specifically designed an IGV vehicle body structure with multi-level safety protection devices, which leads to this invention. Utility Model Content

[0028] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] This invention provides a vehicle body structure for an IGV (Intelligent Guided Vehicle) with multi-level safety protection devices, primarily designed to enhance the safety performance of IGVs in complex operating environments. Through layered design and modular combination, this body structure possesses multiple safety functions, including physical protection, energy buffering, collision detection, drop protection, and audible and visual alarms, significantly improving the vehicle's operational stability and resilience during handling and navigation. This structure is suitable not only for autonomous transportation equipment in logistics and warehousing systems but also for enclosed environments requiring precise navigation and high security, such as hospitals and libraries.

[0030] like Figure 1 As shown, the IGV vehicle body structure includes a vehicle body frame 1, an outer shell protective plate assembly 2, an energy-absorbing anti-collision layer 3, a collision detection module 4, an anti-fall device 5, and an optional audible and visual alarm device 7.

[0031] The vehicle body frame 1 is an integral welded or assembled structure, made of rectangular steel tubing or aluminum alloy profiles, possessing high structural strength and rigidity, and serving as the core load-bearing component of the entire vehicle. The frame can be equipped with upper and lower mounting bases, lateral support beams, embedded wiring channels, and sensor brackets, depending on actual usage requirements, to facilitate the assembly and wiring of other components. This frame can also incorporate finite element structural optimization technology to enhance its rigidity and fatigue resistance.

[0032] Several outer shell protective panel assemblies 2 installed on the exterior of the vehicle body frame 1 include a front protective panel 21, a rear protective panel 22, side protective panels 23, and a top protective panel 24. Each protective panel is connected to the frame by bolts or a snap-fit ​​structure 8, facilitating quick disassembly and maintenance. These protective panels can be made of ABS engineering plastic, composite sheets, or metal sheets, and are used to withstand minor external impacts and protect the internal structure from the effects of external factors such as rain and dust. Preferably, the protective panels adopt a modular design, so that when partial damage occurs, only the damaged parts need to be replaced, reducing maintenance costs.

[0033] like Figure 1 and Figure 3 As shown, an energy-absorbing anti-collision layer 3 is provided between the outer shell protective plate and the vehicle frame 1. This layer is used to absorb external impact energy during a vehicle collision and reduce the impact transmitted to important components inside the vehicle body. Preferably, the energy-absorbing anti-collision layer 3 can be made of materials such as EVA foam, honeycomb aluminum plate, or foamed rubber. It can also be set as a multi-layer structure, that is, multiple layers of buffer materials stacked sequentially along the thickness direction, with each layer having a different density and elastic coefficient to achieve graded buffering and progressive energy absorption effects. In specific environments, energy-absorbing materials with flame-retardant, antibacterial, and anti-aging functions can also be selected to improve the overall environmental adaptability of the system.

[0034] To enhance the vehicle's proactive safety response capabilities during actual operation, a collision detection module 4 is installed inside the energy-absorbing anti-collision layer 3. This module includes multiple piezoelectric sensors and / or Hall effect sensors, which are distributed and installed at key locations on the vehicle structure, such as the front, corners, and sides. These sensors generate electrical signals when subjected to external forces and transmit them to the vehicle's main control system via the CAN bus 6, enabling rapid identification and alarm processing of collision events. The main control system can further determine the collision level based on the sensor data and trigger preset actions, such as deceleration, stopping, or issuing an alarm, thereby improving the vehicle's intelligent safety response capabilities.

[0035] like Figure 2 As shown, to prevent the IGV from falling due to failure to recognize terrain changes during operation, anti-fall devices 5 are installed at the lower corners of the four corners of the vehicle frame 1. These devices include infrared sensors 51 and mechanical limiters 52. The infrared sensors 51 continuously monitor changes in terrain height at the bottom of the vehicle body. When a sudden change or loss of ground level is detected, a signal is immediately sent to the main control system, which can then stop the drive command. The mechanical limiters 52 serve as an emergency stop protection measure, providing physical obstruction in case of system response delays. To improve detection accuracy, the anti-fall device 5 can also be supplemented with an ultrasonic ranging module or a TOF (Time-of-Flight) sensor to achieve millimeter-level terrain recognition, making it suitable for more types of road surfaces and environments.

[0036] like Figure 1As shown, to further enhance the safety of human-machine collaboration, a sound and light alarm device 7 can be installed on the top of the vehicle. In the event of a collision, fall risk, or system malfunction, this device will alert nearby workers through flashing lights and a buzzer. This alarm device can be configured with LEDs of different colors and multi-band buzzers to differentiate alert levels and warning types, thereby enhancing the response efficiency of on-site personnel.

[0037] Furthermore, considering the differentiated functional requirements of IGVs in various operating scenarios, the structural design of this invention provides standardized expansion interfaces and mounting holes to facilitate the installation of other functional modules, such as camera modules, LiDAR, and wireless communication modules, thereby enhancing its automatic navigation, environmental recognition, and remote management capabilities. To meet industrial-grade standards, the structure also meets IP54 and higher protection requirements.

[0038] The structures and functions described in the above embodiments can be expanded to some extent according to actual needs. For example, the collision detection module 4 can be installed not only on the front and rear outer sides of the vehicle body, but also extended to the top corner to enhance the detection range; the anti-fall device 5 can also be combined with ultrasonic or TOF ranging sensors to achieve higher accuracy terrain perception; the protective plate material can also be made of flame-retardant, anti-static and other special modified materials to adapt to specific environmental requirements.

[0039] In summary, this utility model, through the structural support of the vehicle frame 1, the primary protection of the multi-faceted protective plates, the energy absorption of the buffer layer, the intelligent detection of the sensor module, the environmental adaptability of the anti-fall system, and the abnormal warning of the sound and light module, forms a multi-level safety protection IGV vehicle body structure that integrates passive defense and active response. It can effectively improve the reliability and safety of vehicles in complex industrial scenarios and has the beneficial effects of reasonable structure, complete functions, and strong expandability.

[0040] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
