Description

Technical Field

[0001] This utility model relates to the field of protective housing technology, specifically an AGV protective housing. Background Technology

[0002] AGVs, or Automated Guided Vehicles, are transport devices capable of automatically moving along pre-set paths, transporting goods or materials from a starting point to a destination without manual guidance. Their working principle relies on automated guidance systems. For example, some AGVs use a combination of high-precision gyroscopes and encoders for navigation, employing onboard electronic maps for positioning and path planning; others use magnetic navigation (such as the Mihai Heavy-Duty AGV, which navigates using magnetic tape tracks attached to the ground or invisible magnetic strip tracks buried underground) or lidar navigation (such as products that use lidar to create indoor maps for precise positioning and navigation). AGVs require protective casings for operation.

[0003] Chinese Patent No. CN201921525296.3 discloses an AGV protective shell, including a first protective plate, a magnetic base, a spring column, a second protective plate, a buffer layer, an arc-shaped rubber strip, a cooling fan, a fan cover, an air outlet, a fan mounting area, a spring column mounting area, a spring, a cylinder, and a column. Existing technology has poor monitoring performance during use and is prone to impacts. In the event of an impact, the protective shell is easily deformed, potentially damaging the AGV. Utility Model Content

[0004] The purpose of this invention is to provide a protective shell for AGVs to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an AGV protective shell, comprising a shell; protective plates are installed on both sides of the shell, and a buffer is installed between the protective plates and the shell. The buffer consists of a rod, a mounting cylinder, and a spring. One end of the rod is installed inside the protective plate, and the mounting cylinder is installed at both ends of the shell. One end of the rod is inserted into the mounting cylinder, and the spring is installed inside the mounting cylinder on one side of the rod. A controller is installed in the middle of the protective plate, and an infrared obstacle avoidance device is installed in the middle of the controller. A buzzer is installed on the upper side of the controller on one side of the infrared obstacle avoidance device, and a wireless transceiver module is installed on the upper side of the controller on the other side of the infrared obstacle avoidance device. An uninterruptible power supply is installed below the controller.

[0006] Preferably, a corrosion-resistant layer is provided on the outer side of the outer shell, and the corrosion-resistant layer is a corrosion-resistant coating layer.

[0007] Preferably, a raised strip is provided on the inner side of the outer casing, and the raised strip is welded to the inner side of the outer casing.

[0008] Preferably, rollers are provided on both sides of the protective plate, and the rollers are rotatably installed on both sides of the protective plate.

[0009] Preferably, a limiting plate is provided at the front end of the outer shell, and the limiting plate is welded to one end of the insertion rod.

[0010] Preferably, a rubber pad is provided at the front end of the protective plate, and the rubber pad is attached to the front end of the protective plate with adhesive.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Once power is available, the core sensing component, the infrared obstacle avoidance device, immediately begins operation, emitting infrared rays directionally in front of, behind, and to the sides of the AGV's travel path to form a "monitoring barrier." If obstacles such as personnel, equipment, or walls appear in the vicinity, the infrared rays will be quickly reflected and transmitted to the controller immediately. After receiving the signal, the controller instantly analyzes it and issues instructions: on the one hand, it transmits information such as the obstacle's position and distance to the AGV's main control system via the wireless transceiver module, allowing the system to determine whether to slow down, turn, or stop; on the other hand, if the obstacle's distance reaches a preset safety threshold, it immediately triggers a buzzer to sound an audible and visual alarm, reminding personnel to avoid the obstacle, thus buying time for the main control system to respond.

[0013] 2. When the outer shell, i.e. the transport vehicle, is impacted during movement, a buffer is used for cushioning protection. When in use, the buffer guides the impact force on the protective plate through the plug rod, and the impact force is buffered by the spring to avoid large impact force during use, which may cause damage to the outer shell and transport vehicle.

[0014] 3. The rollers are designed to reduce the impact when the protective plate is hit from both sides, and at the same time facilitate steering within a small range;

[0015] 4. The limit plate is designed to restrict the range of motion of the insertion rod, preventing the insertion rod from detaching from the mounting cylinder during use. Attached Figure Description

The buffer 5 is composed of a rod 9, a mounting cylinder 6 and a spring 7. One end of the rod 9 is installed inside the protective plate 2, and the mounting cylinder 6 is installed at both ends of the shell 1. One end of the rod 9 is inserted into the mounting cylinder, and the spring 7 is installed inside the mounting cylinder at one side of the rod 9. A controller 12 is installed in the middle of the protective plate 2, and an infrared obstacle avoidance device 15 is installed in the middle of the controller 12.

[0024] Furthermore, a corrosion-resistant layer 11 is provided on the outer side of the outer shell 1. The corrosion-resistant layer 11 is a corrosion-resistant coating layer. The corrosion-resistant coating layer used in the corrosion-resistant layer 11 has strong corrosion resistance, which can reduce the corrosion of the outer shell 1 during use and extend the service life of the outer shell 1. A protruding strip 10 is provided on the inner side of the outer shell 1. The protruding strip 10 is welded to the inner side of the outer shell 1. The protruding strip 10 is provided to support the outer shell 1 and prevent the outer shell 1 from deforming during use.

[0025] Furthermore, rollers 4 are provided on both sides of the protective plate 2. The rollers 4 are rotatably installed on both sides of the protective plate 2. The rollers 4 are provided to reduce the impact when the protective plate 2 is hit on both sides, and at the same time facilitate steering within a small range. A rubber pad 3 is provided at the front end of the protective plate 2. The rubber pad 3 is attached to the front end of the protective plate 2 with adhesive. The rubber pad 3 is relatively soft and can protect the protective plate 2 when it is hit, so as to prevent the protective plate 2 from deforming or twisting during use.

[0026] Furthermore, a limiting plate 8 is provided at the front end of the outer casing 1. The limiting plate 8 is welded to one end of the insertion rod 9. The limiting plate 8 is provided to limit the range of motion of the insertion rod 9 and prevent the insertion rod 9 from detaching from the mounting cylinder 6 during use.

[0027] The working principle and usage process of this utility model: The outer shell of the AGV transport vehicle protective shell is based on "sensing-response-protection", and relies on the cooperation of various components to achieve dual protection of the vehicle body and the environment. The operation process is compact and connected.

[0028] First, an uninterruptible power supply provides power to the protection system, ensuring that the controller, infrared obstacle avoidance device, buzzer, and wireless transceiver module are powered throughout the process, thus preventing protection failure due to power outages. This is the basis for function activation.

[0029] Once the power is available, the core sensing component, the infrared obstacle avoidance device, immediately starts working, emitting infrared rays in a directional manner in front of, behind, and to the sides of the AGV's travel path to form a "monitoring barrier." If obstacles such as people, equipment, or walls appear in the vicinity, the infrared rays will be quickly reflected and transmitted to the controller immediately.

[0030] After receiving the signal, the controller instantly analyzes it and issues instructions: on the one hand, it transmits information such as the position and distance of the obstacle to the AGV main control system through the wireless transceiver module, so that the system can determine whether to slow down, turn, or stop; on the other hand, if the distance to the obstacle reaches the preset safety threshold, it immediately triggers the buzzer to sound an audible and visual alarm, reminding personnel to avoid the obstacle, thus buying time for the main control system to respond.

[0031] In the event of a sudden delay in the main control system or rapid movement of obstacles, causing a minor collision with the AGV, the protective plate will first contact the obstacle. The impact force will push the protective plate towards the outer shell, causing the inner insert rod to slide into the mounting cylinder, compressing the spring inside. The spring, through its elastic deformation, absorbs most of the impact force, preventing damage to core components such as the AGV's drive system and cargo platform. After the impact force dissipates, the spring returns to its original position, pushing the insert rod and protective plate back to their original positions, ensuring the protective system can be reused.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
