Description

Technical Field

[0001] The utility model relates to the technical field of AGV vehicles, and particularly relates to a radar support plate for an AGV vehicle. Background Art

[0002] With the rapid development of Industry 4.0, the demand for AGVs is increasing. For the radar used for obstacle avoidance on AGVs, in order to accurately measure the specific position and larger measurement range of obstacles, the installation accuracy requirements of the obstacle avoidance radar are often relatively high. The higher the levelness of the installation of the obstacle avoidance radar, the more accurate the measured position of the obstacle. And the obstacle avoidance radar is usually installed at the front and rear ends of the AGV vehicle for monitoring obstacles.

[0003] At present, during the transportation of goods by most AGV vehicles, when the transportation workload is large, collisions are likely to occur between AGV vehicles, which is likely to cause damage to the AGV vehicles. Therefore, the patent of a double-drive AGV vehicle with the publication number CN213973496U includes a vehicle body, wheels and a drive wheel assembly, and the wheels and the drive wheel assembly are fixedly installed on the chassis at the bottom of the vehicle body; by setting anti-collision strips at the front and rear ends of the AGV vehicle, the overall safety of the AGV vehicle is increased, and the operation reliability of the equipment is ensured.

[0004] However, since the obstacle avoidance radar on the AGV vehicle is located at the front and rear ends of the AGV vehicle, when collisions occur between the front and rear ends of AGV vehicles, due to the lack of good protection for the obstacle avoidance radar, the impact object is likely to collide with the surface of the obstacle avoidance radar, causing damage or skew to its surface, thus affecting the accuracy of measuring the position of obstacles.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above defects. Content of the Utility Model

[0006] The purpose of the utility model is to provide a radar support plate for an AGV vehicle that can effectively solve the above technical problems.

[0007] To achieve the purpose of the utility model, the following technical scheme is adopted: A radar support plate for an AGV vehicle, comprising: a radar support seat for an AGV vehicle, a steering motor is fixedly installed at the middle position of the top of the radar support seat for an AGV vehicle, and a tray is fixedly installed at the output end of the steering motor. Obstacle avoidance radars are fixedly installed on both the front and rear sides of the top of the radar support seat for an AGV vehicle. Anti-collision buffer plates are arranged on the side walls of both the front and rear sides of the radar support seat for an AGV vehicle, and an anti-collision shielding component for protecting the front side of the obstacle avoidance radar is arranged between one side of the anti-collision buffer plate and the inside of the radar support seat for an AGV vehicle.

The other end of the activity rod is fixedly connected with a pressing block. The shielding block is slidably installed inside the through groove. The bottom of the shielding block is placed on one side of the top of the pressing block. A first return spring is sleeved on the surface of the activity rod, and one end of the first return spring is fixedly connected to one side of the anti-collision buffer plate. The other end of the first return spring is fixedly connected to the side wall of the radar support base of the AGV vehicle. A protection component is arranged between the bottom wall of the cavity and one side of the shielding block.

[0009] Furthermore, one side of the top of the pressing block is set as an inclined surface, and one side of the bottom of the shielding block is set as an inclined surface that matches the inclined surface on the top of the pressing block.

[0010] Furthermore, the protection component includes: a piston cylinder. The piston cylinder is fixedly installed on the bottom wall of the cavity.

One side of the airbag is fixedly installed on the surface of one side of the shielding block.

[0011] Furthermore, activity grooves are symmetrically opened on the side walls on the front and rear sides of the radar support base of the AGV vehicle, and a guiding rod is horizontally and movably inserted inside the activity groove. One end of the guiding rod is fixedly installed on the surface of one side of the anti-collision buffer plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects: In the utility model, a radar support plate for an AGV vehicle is provided with components such as an anti-collision buffer plate, an anti-collision shielding component, and a protection component. When the anti-collision buffer plate is subjected to external force collision and extrusion, through the setting of the anti-collision shielding component, the shielding block slidably installed inside the through groove can move upward to shield the front side of the obstacle avoidance radar, preventing the impact object from colliding with the surface of the obstacle avoidance radar, causing damage or skew on its surface, and affecting the accuracy of measuring the position of the obstacle. At the same time, under the action of the protection component, the airbag follows the shielding block to move upward and expand, which can prevent the shielding block from coming into hard contact with the obstacle avoidance radar, thereby further improving the protection effect of the obstacle avoidance radar.

[0021] As Figures 1 to 4 shown, a radar support plate for an AGV vehicle of the present utility model includes: an AGV vehicle radar support base 1. A steering motor 2 is fixedly installed at the middle position of the top of the AGV vehicle radar support base 1, and a tray 3 is fixedly installed at the output end of the steering motor 2. Obstacle avoidance radars 4 are fixedly installed on both the front and rear sides of the top of the AGV vehicle radar support base 1. Anti-collision buffer plates 5 are provided on the side walls of both the front and rear sides of the AGV vehicle radar support base 1, and an anti-collision shielding assembly 6 for protecting the front side of the obstacle avoidance radar 4 is provided between one side of the anti-collision buffer plate 5 and the inside of the AGV vehicle radar support base 1. Driving wheels 101 are installed around the bottom of the AGV vehicle radar support base 1. When the anti-collision buffer plate 5 is externally collided and squeezed, due to the setting of the anti-collision shielding assembly 6, the shielding block 605 slidably installed in the through groove 602 can move upward to shield the front side of the obstacle avoidance radar 4, avoiding the impact object from colliding on the surface of the obstacle avoidance radar 4, causing damage or skew on its surface and affecting the accuracy of measuring the position of the obstacle.

[0022] The anti-collision shielding component 6 includes: a cavity 601, a through groove 602, and a shielding block 605. The cavity 601 is opened on one side inside the radar support base 1 of the AGV cart. The through groove 602 is opened on one side of the top of the radar support base 1 of the AGV cart. The bottom of the through groove 602 is communicated with the inside of the adjacent cavity 601. An activity rod 603 is movably inserted horizontally inside the cavity 601, and one end of the activity rod 603 is fixedly connected to one side of the adjacent anti-collision buffer plate 5. The other end of the activity rod 603 is fixedly connected with a pressing block 604. The shielding block 605 is slidably installed inside the through groove 602. The bottom of the shielding block 605 is placed on one side of the top of the pressing block 604. A first return spring 606 is sleeved on the surface of the activity rod 603, and one end of the first return spring 606 is fixedly connected to one side of the anti-collision buffer plate 5, and the other end of the first return spring 606 is fixedly connected to the side wall of the radar support base 1 of the AGV cart. A protection component 7 is arranged between the bottom wall of the cavity 601 and one side of the shielding block 605. When the anti-collision buffer plate 5 is collided and extruded by an external force, the anti-collision buffer plate 5 pushes the activity rod 603 on one side to move inside the cavity 601 on one side of the radar support base 1 of the AGV cart, so that the inclined surface of the pressing block 604 at the other end of the activity rod 603 extrudes the inclined surface at the bottom of the shielding block 605 slidably installed on the inner wall of the through groove 602, thereby moving the shielding block 605 upward to shield the front side of the obstacle avoidance radar 4, avoiding the impact object from colliding on the surface of the obstacle avoidance radar 4, causing damage or skew on its surface, and affecting the accuracy of measuring the position of the obstacle.

[0023] One side of the top of the pressing block 604 is set as an inclined surface, and one side of the bottom of the shielding block 605 is set as an inclined surface matching the inclined surface at the top of the pressing block 604. Through the setting of the inclined surface at the top of the pressing block 604 and the inclined surface at the bottom of the shielding block 605, it is convenient for the pressing block 604 to extrude and push the shielding block 605 to move upward to shield the front side of the obstacle avoidance radar 4.

[0024] The protection component 7 includes: a piston cylinder 701, which is fixedly installed on the bottom wall of the cavity 601. A piston rod 702 is movably installed inside one end of the piston cylinder 701, and one end of the piston rod 702 extends to the outside of one end of the piston cylinder 701. A connecting block 703 is fixedly installed at one end of the piston rod 702, and one side of the connecting block 703 is placed on the surface of one side of the extrusion block 604. A second return spring 704 is sleeved on the surface of the piston rod 702, and one end of the second return spring 704 is fixedly connected to one side of the connecting block 703, and the other end of the second return spring 704 is fixedly connected to the surface of one end of the piston cylinder 701. A connecting hose 705 is fixedly connected to the top of the other end of the piston cylinder 701, and one end of the connecting hose 705 is fixedly connected to an airbag 706. One side of the airbag 706 is fixedly installed on the surface of one side of the shielding block 605. When the extrusion block 604 squeezes the shielding block 605 to move upward to shield the front side of the obstacle avoidance radar 4, the extrusion block 604 simultaneously squeezes the connecting block 703 at one end of the piston rod 702, so that the other end of the piston rod 702 squeezes the air inside the piston cylinder 701, and the air inside the piston cylinder 701 enters the inside of the airbag 706 through the connecting hose 705. At this time, the airbag 706 moves upward following the shielding block 605 and expands. The expanded airbag 706 can prevent the shielding block 605 from making hard contact with the obstacle avoidance radar 4, thereby further improving the protection effect of the obstacle avoidance radar 4.

[0025] Activity grooves 102 are symmetrically opened on the side walls on the front and rear sides of the radar support base 1 of the AGV vehicle, and a guide rod 501 is movably inserted inside the activity grooves 102. One end of the guide rod 501 is fixedly installed on the surface of one side of the anti-collision buffer plate 5. Through the arrangement of the guide rod 501, it plays a guiding role in the movement of the anti-collision buffer plate 5 and improves its stability.

[0026] Working principle: During the use of the AGV vehicle, when the anti-collision buffer plates 5 at the front and rear ends of the AGV vehicle are externally collided and squeezed, the anti-collision buffer plate 5 pushes the movable rod 603 on one side to move inside the cavity 601 on one side of the radar support base 1 of the AGV vehicle, so that the inclined surface of the extrusion block 604 at the other end of the movable rod 603 squeezes the inclined surface at the bottom of the shielding block 605 slidably installed on the inner wall of the through groove 602, thereby causing the shielding block 605 to move upward to shield the front side of the obstacle avoidance radar 4, avoiding the impact object from colliding on the surface of the obstacle avoidance radar 4 and affecting the accuracy of measuring the position of the obstacle. And when the extrusion block 604 squeezes the shielding block 605 to move upward to shield the front side of the obstacle avoidance radar 4, the extrusion block 604 simultaneously squeezes the connecting block 703 at one end of the piston rod 702, so that the other end of the piston rod 702 squeezes the air inside the piston cylinder 701, and the air inside the piston cylinder 701 enters the inside of the airbag 706 through the connecting hose 705. At this time, the airbag 706 moves upward following the shielding block 605 and expands. The expanded airbag 706 can prevent the shielding block 605 from making hard contact with the obstacle avoidance radar 4, thereby further improving the protection effect of the obstacle avoidance radar 4.
