Description

Technical Field

[0001] This utility model relates to the field of protection technology for warehouse exploration robots, specifically a front-mounted anti-collision component for warehouse exploration robots. Background Technology

[0002] Warehouse exploration robots play a vital role in modern warehousing and logistics management, and their front-end collision avoidance structure is a key component ensuring their safe and efficient operation. The main function of this structure is to prevent the robot from colliding with surrounding obstacles during movement, thereby protecting both the robot itself and the surrounding environment. The front-end collision avoidance structure typically consists of various sensors (such as lidar, ultrasonic sensors, and infrared sensors), cushioning materials, a robotic arm or protective cover, and an intelligent control system. The sensors monitor the environment in front of the robot in real time, and when an obstacle is detected, the control system quickly calculates the distance and position of the obstacle, then issues a deceleration or stop command to ensure the robot can avoid it in time. In addition, the design of the cushioning material enables it to absorb some of the impact force when a collision occurs, reducing damage to the robot and obstacles. However, at present, the front anti-collision component of the warehouse exploration robot uses a spring to force the cushioning part away from the body in order to ensure that its own cushioning part can be reset in time. Due to the limitation of the spring length, it will occupy a large space in the robot's forward direction. In the warehouse environment, space is often limited, especially in the aisles between shelves. The robot needs to move flexibly in narrow areas. If the front anti-collision component occupies too much space, it will prevent the robot from passing through narrow aisles smoothly, reducing its mobility. Utility Model Content

[0003] The purpose of this utility model is to provide a front-mounted anti-collision component for a warehouse exploration robot. The C-port sheet metal cover is bolted onto the warehouse exploration robot, and two steel columns perpendicular to the ground are installed on the front panel. A double-column planar elastic reset structure is set on the two steel columns. The double-column planar elastic reset structure supports the front arc-shaped baffle, thereby making the anti-collision component flat and reducing the space occupied by the anti-collision component in the forward direction of the warehouse exploration robot, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a front anti-collision component for a warehouse exploration robot, comprising a C-port sheet metal cover and two front guardrails symmetrically welded and fixed at both ends of the C-port sheet metal cover. A U-shaped guardrail is welded to the surface of the C-port sheet metal cover on one side of each front guardrail. A front arc-shaped baffle that can slide in the Y-axis direction is installed on the outer wall of the two U-shaped guardrails away from the C-port sheet metal cover. Steel columns are fixed on both sides of the surface of each front guardrail. A double-column planar elastic reset structure for connecting with the steel columns is installed on the back of each front arc-shaped baffle. The double-column planar elastic reset structure is used to force the front arc-shaped baffle to always stay away from the U-shaped guardrail.

[0005] Preferably, several positioning holes are provided on the outer walls of both sides of the C-port sheet metal cover.

[0006] Preferably, the C-shaped sheet metal cover, the front rail panel, and the U-shaped guardrail are all made of alloy steel components.

[0007] Preferably, two triangular seats are fixed on both sides of the front panel surface, and a short shaft is fixed between the two triangular seats. Both ends of the steel column are integrally formed with T-shaped heads, and the T-shaped heads and the short shaft are interlocked.

[0008] Preferably, both sides of the back of the front arc-shaped baffle are fixed with guide posts that extend to the outside of the U-shaped guardrail, and a baffle plate is fixed at the end of the guide post away from the front arc-shaped baffle.

[0009] Preferably, the double-column planar elastic reset structure includes an isosceles trapezoidal platform integrally formed on the back of the front arc baffle, trapezoidal sliding sleeves slidably installed at both ends of the steel column surface, and a rectangular corner stop integrally formed at the corner position on the back of the U-shaped guardrail. A reset spring is fitted on the surface of the steel column between the rectangular corner stop and the trapezoidal sliding sleeve. The isosceles trapezoidal platform and the trapezoidal sliding sleeve are in sliding contact through the inclined surface.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the front anti-collision component of the warehouse exploration robot adopts a double-column planar elastic reset structure, which can effectively reduce the space occupation of the anti-collision component in the forward direction of the warehouse exploration robot. The resulting flat design allows the robot to move flexibly in a limited space, avoiding the decrease in work efficiency caused by excessive space occupation. Thus, in warehouses with high-density storage, the robot can move freely in the narrow aisles between shelves, maximizing the use of warehouse space.

[0011] The dual-column planar elastic reset structure provides better support for the front arc baffle, enhancing the structural stability of the entire anti-collision component. The vertical design of the steel columns allows the baffle to effectively disperse the impact force when subjected to external impact, reducing the impact on the robot body. Furthermore, the dual-column planar elastic reset structure can quickly deform and reset itself when encountering obstacles, thereby effectively mitigating the impact of collisions. This flexible response mechanism enables the robot to quickly adapt and take corresponding measures when dealing with different types of obstacles, reducing the damage caused by collisions.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5An embodiment of this utility model provides a front anti-collision component for a warehouse exploration robot, including a C-shaped sheet metal cover 1 and two front guardrails 2 symmetrically welded and fixed at both ends of the surface of the C-shaped sheet metal cover 1. A U-shaped guardrail 3 is welded to the surface of the C-shaped sheet metal cover 1 on one side of the front guardrail 2. A front arc-shaped baffle 5 that can slide in the Y-axis direction is installed on the outer wall of the two U-shaped guardrails 3 away from the C-shaped sheet metal cover 1. Steel columns 4 are fixed on both sides of the surface of the two front guardrails 2. A double-column planar elastic reset structure 6 for connecting with the steel column 4 is installed on the back of the front arc-shaped baffle 5. The double-column planar elastic reset structure 6 is used to force the front arc-shaped baffle 5 to always stay away from the U-shaped guardrail 3.

[0020] Several positioning holes 101 are provided on the left and right outer walls of the C-shaped sheet metal cover 1. The C-shaped sheet metal cover 1, the front panel 2, and the U-shaped guardrail 3 are all made of alloy steel components. The C-shaped sheet metal cover 1 is fixed to the front shell of the robot's front end through the positioning holes 101 on the left and right outer walls and bolts.

[0021] Two triangular seats are fixed on both sides of the surface of the front railing 2, and a short shaft is fixed between the two triangular seats. The two ends of the steel column 4 are integrally formed with T-shaped heads, and the T-shaped heads and short shafts are interlocked. Guide posts 501 that penetrate to the outside of the U-shaped guardrail 3 are fixed on both sides of the back of the front arc baffle 5. A baffle plate is fixed at the end of the guide post 501 away from the front arc baffle 5. When the front arc baffle 5 contacts the obstacle, the front arc baffle 5 slides relative to the U-shaped guardrail 3 through the guide post 501, that is, the front arc baffle 5 can move stably in the direction of the U-shaped guardrail 3. A baffle plate is installed at the end of the guide post 501 away from the front arc baffle 5 to prevent the front arc baffle 5 and the U-shaped guardrail 3 from slipping.

[0022] The double-column planar elastic reset structure 6 includes an isosceles trapezoidal platform 601 integrally formed on the back of the front arc-shaped baffle 5, trapezoidal sliding sleeves 602 slidably installed at both ends of the surface of the steel column 4, and a rectangular corner stop 604 integrally formed at the corner of the back of the U-shaped guardrail 3. A reset spring 603 is fitted on the surface of the steel column 4 between the rectangular corner stop 604 and the trapezoidal sliding sleeves 602. The isosceles trapezoidal platform 601 and the trapezoidal sliding sleeves 602 slide in contact through a ramp surface. Each of the two ramp surfaces slides into contact with the inclined surface of a trapezoidal sleeve 602, thereby using the isosceles trapezoidal platform 601 to force the trapezoidal sleeve 602 to move closer to the rectangular stop angle 604. Subsequently, the return spring 603 is squeezed by the trapezoidal sleeve 602 and the rectangular stop angle 604. After the front arc baffle 5 separates from the obstacle, the return spring 603 forces the trapezoidal sleeve 602, the isosceles trapezoidal platform 601, and the front arc baffle 5 to return to their original positions, thereby reducing the stalling or damage caused by the collision.

[0023] In this embodiment, the operator first bolts the C-port sheet metal cover 1 to the front of the exploration robot. The C-port sheet metal cover 1 provides basic protection and also provides a foundation structure for the installation of other components. Under normal operating conditions, the exploration robot moves at a preset speed and direction. At this time, the C-port sheet metal cover 1, the front rail 2, and the U-shaped guardrail 3 form a protective shell. The front arc-shaped baffle 5 acts as a guide in front of the exploration robot. During the robot's operation, if an obstacle appears in front, the front arc-shaped baffle 5 will be the first to contact the obstacle. The design of the front arc-shaped baffle 5 allows it to effectively disperse the collision force and reduce the impact on the robot. The robot body is directly impacted, and during this process, the double-column planar elastic reset structure 6 begins to function. Its elastic properties allow the front arc-shaped baffle 5 to move backward, absorbing some of the collision energy. During this process, the steel column 4 provides necessary support, ensuring that the rapid movement of the front arc-shaped baffle 5 does not cause the entire structure to become unstable. At the moment of impact, the elastic deformation of the double-column planar elastic reset structure 6 can effectively disperse the collision force and reduce the impact on other parts of the robot. After the collision, the elastic properties of the double-column planar elastic reset structure 6 allow the robot to quickly reset and return to its original position, ensuring that the robot can continue to operate normally.
