Description

Technical Field

[0001] This application relates to the technical field of AGV vehicles, and specifically to a protective device for AGV vehicles. Background Art

[0002] An AGV vehicle is a driverless vehicle that can operate autonomously, specifically designed to perform various transportation and handling tasks in industrial and commercial environments. They are usually used to replace or assist traditional manual handling and transportation operations to improve efficiency, reduce costs, and enhance the degree of automation of production processes.

[0003] Existing AGV vehicles only rely on sheet metal shells for protection and do not have a dedicated protection mechanism. For collisions or accidental impacts at relatively high speeds, their protection ability is relatively limited. Only relying on the weak sheet metal shell for protection, the safety risk is relatively high. Collisions at relatively high speeds may cause serious damage and even affect the safety of operators. Summary of the Utility Model

[0004] In view of this, the purpose of the present utility model is to solve the disadvantages existing in the background art and propose a protective device for AGV vehicles to solve the problems existing in the prior art.

[0005] To achieve the above object, the present utility model provides a protective device for AGV vehicles, including a vehicle body. A heat sink is provided on the outer surface of the vehicle body. A fixed frame is fixedly connected to the outer surface of the vehicle body. A load-relieving frame is movably installed around the fixed frame through a buffer mechanism. A rotating shaft is fixedly connected to the inner side of the load-relieving frame. A rubber load-relieving cylinder is rotatably connected to the outer surface of the rotating shaft. A flow-disturbing mechanism is provided inside the load-relieving frame. The rubber load-relieving cylinder itself has a certain elastic buffering performance.

[0006] Preferably, the buffer mechanism includes a first guiding cylinder fixedly connected to the outer surface of the fixed frame. A spring is provided inside the first guiding cylinder. The buffer mechanism can effectively buffer and relieve the force after the AGV vehicle is impacted, reducing the damage to the vehicle.

[0007] Preferably, one end of the spring away from the first guiding cylinder is fixedly connected to a second guiding cylinder. One end of the second guiding cylinder away from the spring is fixedly connected to a fixed bracket. The outer surface of the fixed bracket is fixedly connected to the outer surface of the load-relieving frame.

[0008] Preferably, the flow-disturbing mechanism includes a fixed ring fixedly connected to the inner side of the load-relieving frame. A ball is provided inside the fixed ring. The flow-disturbing mechanism can be triggered simultaneously when the buffer mechanism is triggered, strengthening the agitation of the air flow around the heat sink and improving the heat dissipation effect.

[0009] Preferably, an inner shaft is rotatably connected to the inner side of the fixed ring, and a spoiler frame is fixedly connected to one end of the inner shaft away from the fixed ring.

[0010] Preferably, spoiler plates are arranged on the spoiler frame.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. For the protection device of the AGV vehicle, the design of the rubber force-relieving cylinder and the spring system effectively alleviates and disperses the force generated during impact. The rubber force-relieving cylinder, through its buffering performance and rotational characteristics, first absorbs the impact energy and changes the impact direction, so that the vehicle after impact no longer moves in a straight line continuously. Cooperating with the spring, it effectively alleviates and disperses the force generated during impact, so as to reduce the force transmitted to the vehicle body structure by the impact, thereby reducing the direct impact on the vehicle body structure and electronic equipment and lowering the risk of damage.

[0013] 2. For the protection device of the AGV vehicle, the design of the force-relieving frame not only considers the mechanical protection during impact, but also enhances the agitation of the air flow around the heat sink by linking the spoiler frame and the spoiler plates. This design enables the heat sink to make more effective use of the surrounding air and improves the heat dissipation effect. Especially during high-load or long-term operation, this improved heat dissipation effect can extend the service life and stability of the electronic equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figures 1-6 A protective device for an AGV vehicle comprises a vehicle body 1, a heat sink 2 is arranged on the outer surface of the vehicle body 1, a fixed frame 3 is fixedly connected to the outer surface of the vehicle body 1, a force unloading frame 8 is movably installed on the periphery of the fixed frame 3 through a buffer mechanism, a rotating shaft 9 is fixedly connected to the inner side of the force unloading frame 8, a rubber force unloading cylinder 10 is rotatably connected to the outer surface of the rotating shaft 9, and a spoiler mechanism is arranged on the inner side of the force unloading frame 8.

[0023] Through the above technical solution, the side of the body 1 of the AGV car will trigger the buffer mechanism after being hit. The buffer mechanism cooperates with the rubber unloading cylinder 10 to effectively buffer and unload the impact force. At the same time, the spoiler mechanism will be triggered synchronously to improve the heat dissipation effect of the heat sink 2.

[0024] Specifically, the buffer mechanism includes a first guide tube 4 fixedly connected to the outer surface of the fixed frame 3 , and a spring 5 is arranged inside the first guide tube 4 .

[0025] Through the above technical solution, the first guide tube 4 and the second guide tube 6 are connected via the spring 5, so the spring 5 can be deformed along the force direction after being subjected to force.

[0026] Specifically, one end of the spring 5 away from the first guide tube 4 is fixedly connected to the second guide tube 6 , and one end of the second guide tube 6 away from the spring 5 is fixedly connected to the fixing frame 7 , and the outer surface of the fixing frame 7 is fixedly connected to the outer surface of the unloading frame 8 .

[0027] Through the above technical solution, after the rubber unloading cylinder 10 in the unloading frame 8 is hit, the unloading frame 8 will transmit the impact force to the spring 5 through the four sets of fixing frames 7 at the corners.

[0028] Specifically, the spoiler mechanism includes a fixing ring 11 fixedly connected to the inner side of the unloading frame 8 , and a ball 12 is arranged inside the fixing ring 11 .

[0029] Through the above technical solution, the inner shaft 13 can rotate along the balls 12, and the balls 12 can effectively improve the smoothness of the inner shaft 13 during the rotation process.

[0030] Specifically, the inner side of the fixing ring 11 is rotatably connected to the inner shaft 13 , and one end of the inner shaft 13 away from the fixing ring 11 is fixedly connected to the spoiler frame 14 .

[0031] Through the above technical solution, during the momentary shaking of the unloading frame 8, the spoiler frame 14 can rotate synchronously with the inner shaft 13.

[0032] Specifically, spoiler plates 15 are provided on the spoiler frame 14.

[0033] Through the above technical solution, during the rotation of the spoiler frame 14, the spoiler plates 15 will be synchronously toggled, thereby churning the nearby air flow through the spoiler plates 15 to accelerate the air flow.

[0034] Working principle: When the side of the vehicle body 1 of this AGV vehicle is impacted, the rubber unloading cylinder 10 with a certain buffering performance will be impacted first. During this process, the rubber unloading cylinder 10 will rotate along the rotating shaft 9, buffering a certain amount of the impact force and unloading part of the impact force at the same time, thereby changing the impact direction of the impact vehicle, so that the impact vehicle will not continue to ram around, but will change its direction to a certain extent. This characteristic helps to reduce the inertia and continuous impact effect after the impact, making the overall impact event more controllable and reducing damage. The rubber unloading cylinder 10 can absorb and transfer the impact force, and this mechanism effectively reduces the impact force directly received by the vehicle body 1 during the impact, thereby reducing the risk of damage to the structure and electronic equipment of the vehicle body 1. During this period, the unloading frame 8 will transmit the impact force to the spring 5 through the fixing frame 7 and the second guiding cylinder 6. After being impacted, the spring 5 will deform and buffer the impact force to reduce the impact damage received by the vehicle body 1. So far, the rubber unloading cylinder 10 and the spring 5 system cooperate to effectively relieve and disperse the force generated during the impact, so as to reduce the force transmitted to the structure of the vehicle body 1, and play the role of protecting the vehicle body 1 and its internal electronic components. At the same time, during the process of the unloading frame 8 being impacted, the inner shaft 13 inside the unloading frame 8 will rotate inside the fixing ring 11 with the cooperation of the ball bearings 12, thereby driving the spoiler frame 14 and the spoiler plates 15 to rotate synchronously. During this period, the spoiler frame 14 cooperates with the spoiler plates 15 to increase the agitation of the air flow near the heat sink 2, thereby improving the heat dissipation effect of the heat sink 2. This mechanism, through the design of the unloading frame 8, utilizes the energy generated during the impact to drive the spoiler frame 14 and the spoiler plates 15, so as to enhance the control and agitation of the air flow around the heat sink 2, thereby effectively improving the heat dissipation effect of the heat sink 2.

[0035] In summary, the comprehensive design in this application is not only a response to the impact event, but also improves the overall performance and service life of the vehicle while protecting the vehicle and internal equipment, thereby ensuring the reliable operation and safety of the vehicle in a complex environment.
