Description

Technical Field

[0001] This utility model relates to the field of competitive machine technology, specifically to a competitive machine vehicle with a quick-change pusher structure. Background Technology

[0002] Competitive robots are devices used to participate in robot competitions. Operators modify these robots to enable them to compete. A competitive robot ball-pushing game is a robot competition that combines mechanical design, automatic control, and strategic combat, where points are scored by pushing a ball into the opponent's goal.

[0003] In the prior art, patent announcement number CN211328141U discloses a ball-pushing mechanism for an intelligent soccer competition robot. Its structure includes a connecting plate with a fitting groove and an adjusting bolt. The fitting groove is located on the right side inside the connecting plate. The adjusting bolt is threaded to the upper part of the connecting plate. A rotating ball is disposed inside the fitting groove. The rotating ball has a rough surface and a push plate. The rough surface is attached to the outer surface of the rotating ball. The push plate is welded to the right end of the rotating ball. The push plate has a support plate and protrusions. The support plate is welded to the lower end of the push plate. The protrusions are evenly distributed on the inner surface of the push plate. A bearing is disposed inside the support plate, and a fixed shaft is disposed at the center of the bearing.

[0004] During the game, the robotic car uses its designed mechanical structure to move a pusher plate, aiming to accurately push the ball into the goal. However, the robotic car can only rely on the movement of the pusher plate to accomplish this task; it cannot directly shoot the ball into the goal. Therefore, to achieve the goal, the robotic car needs to perform a series of complex movements, which usually means it must travel a relatively long distance to successfully push the ball into the goal. To address this, a competitive robotic car with a quick-change pusher structure is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a racing robot with a quick-change pusher structure to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a competitive robot car with a quick-change pusher structure, including a robot car, a mounting plate fixedly installed at the front end of the robot car, a pusher plate fixedly installed on the mounting plate, an inlet and outlet hole opened on the pusher plate, a ball pushing mechanism fixedly installed inside the robot car, the ball pushing mechanism including a positioning sleeve fixedly installed inside the robot car, a storage spring provided inside the positioning sleeve, a ball pushing rod movably installed inside the positioning sleeve, and a thrust adjustment mechanism installed below the positioning sleeve.

[0007] Preferably, the ball-pushing mechanism further includes a sliding support foot fixedly installed on the side wall of the ball-pushing stick and a movable groove opened on the positioning sleeve. A ball-pushing cap is fixedly installed at one end of the ball-pushing stick, and a movable slider is fixedly installed at the other end of the ball-pushing stick.

[0008] Preferably, a positioning frame is fixedly installed inside the robot car, and the positioning sleeve is fixedly installed inside the robot car through the positioning frame, and the push rod inside the positioning sleeve is aligned with the inlet and outlet holes on the push plate.

[0009] Preferably, the sliding support foot is slidably mounted on the positioning sleeve via a movable groove, the push rod is movably mounted inside the positioning sleeve via a movable slider, one end of the storage spring is connected to the movable slider, and the other end of the storage spring is connected to the end of the positioning sleeve.

[0010] Preferably, the thrust adjustment mechanism includes a mounting plate fixedly installed inside the robot car. A motor is fixedly installed on one side of the mounting plate, and positioning rods are fixedly installed on both sides of the mounting plate. A drive screw is rotatably installed in the middle of the mounting plate. A screw slider is slidably installed on the positioning rod and threaded onto the drive screw. A movable shaft is rotatably installed on the screw slider. Iron levers are fixedly installed at both ends of the movable shaft. A limiting cable is provided between the iron levers and the screw slider. Electromagnets are fixedly installed on both sides of the screw slider.

[0011] Preferably, the output end of the motor is provided with a coupling, and the drive screw is fixedly installed at the output end of the motor through the coupling.

[0012] Preferably, the iron lever is rotatably mounted on the lead screw slider via a movable shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this application, when the electromagnet is turned off, the iron lever is released, causing the sliding support to lose its obstruction. Subsequently, the energy storage spring releases its stored energy, which drives the push stick forward rapidly and strikes the ball inside the push plate. This impact causes the ball to be shot towards the goal from a greater distance, thus completing the shooting task without the need for the robotic vehicle to move to the goal, significantly improving the efficiency of the shooting task.

[0015] In this application, after the motor starts, the lead screw it drives rotates, which in turn moves the lead screw slider backward. As the lead screw slider moves backward, the iron lever also moves backward, causing the sliding support to move backward, thereby storing energy in the energy storage spring. By precisely controlling the stroke of the lead screw slider, the compression of the energy storage spring can be adjusted, thus achieving fine control of the push force of the push stick, allowing the ball to be launched at different speeds.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a competitive robot car with a quick-change pusher structure, including a robot car 1. A mounting plate 2 is fixedly installed at the front end of the robot car 1, and a pusher plate 3 is fixedly installed on the mounting plate 2. An inlet and outlet hole 4 is opened on the pusher plate 3. A ball pushing mechanism 5 is fixedly installed inside the robot car 1, and a thrust adjustment mechanism 6 is installed below the positioning sleeve 503. Through the cooperation of the ball pushing mechanism 5 and the thrust adjustment mechanism 6, the ball can be shot towards the goal from a greater distance, greatly improving the efficiency of the goal-scoring task.

[0023] like Figure 2 and Figure 3As shown, the ball-pushing mechanism 5 includes a positioning sleeve 503 fixedly installed inside the robot car 1. A storage spring 506 is provided inside the positioning sleeve 503. A ball-pushing rod 502 is movably installed inside the positioning sleeve 503. The ball-pushing mechanism 5 also includes a sliding support leg 504 fixedly installed on the side wall of the ball-pushing rod 502 and a movable slide groove 507 opened on the positioning sleeve 503. A ball-pushing cap 501 is fixedly installed at one end of the ball-pushing rod 502, and a movable slider 505 is fixedly installed at the other end of the ball-pushing rod 502. A positioning frame is fixedly installed inside the robot car 1. The positioning sleeve 503 is fixedly installed inside the robot car 1 through the positioning frame, and the ball-pushing rod 502 inside the positioning sleeve 503 is aligned with the inlet and outlet holes 4 on the push plate 3.

[0024] Specifically, after the electromagnet 607 is deactivated, it releases the connected iron lever 608. Once the iron lever 608 is released, the sliding foot 504 loses its original blocking function. At this time, the energy storage spring 506 begins to function, rapidly releasing its stored energy. During the energy release process, the energy storage spring 506 pushes the pusher stick 502 forward. As the pusher stick 502 moves forward, it strikes the ball inside the push plate 3, giving the ball sufficient kinetic energy. Subsequently, under the force of the push, the ball is launched towards the goal from a greater distance. This process eliminates the need for the robot car 1 to move near the goal, thus significantly improving the efficiency of the goal-scoring task.

[0025] like Figure 2 and Figure 4 As shown, the thrust adjustment mechanism 6 includes a mounting frame 602 fixedly installed inside the robot car 1. A motor 601 is fixedly installed on one side of the mounting frame 602. Positioning rods 603 are fixedly installed on both sides of the mounting frame 602. A drive screw 604 is rotatably installed in the middle of the mounting frame 602. A screw slider 609 is slidably installed on the positioning rods 603 and threaded onto the drive screw 604. A movable shaft 605 is rotatably installed on the screw slider 609. Iron levers 608 are fixedly installed at both ends of the movable shaft 605. A limiting cable 606 is provided between the iron levers 608 and the screw slider 609. Electromagnets 607 are fixedly installed on both sides of the screw slider 609. A coupling is provided at the output end of the motor 601. The drive screw 604 is fixedly installed at the output end of the motor 601 through the coupling.

[0026] Specifically, when motor 601 is started, it begins to rotate, causing drive screw 604 to rotate accordingly. As drive screw 604 rotates, screw slider 609 is subjected to force and moves backward. During the backward movement of screw slider 609, it further drives iron lever 608 to move backward as well. The backward movement of iron lever 608 triggers sliding foot 504 to move backward, and this series of movements ultimately causes energy storage spring 506 to begin accumulating energy. By precisely controlling the movement distance of screw slider 609, we can adjust the degree of compression of energy storage spring 506. Adjusting the degree of spring compression can then control the magnitude of the pushing force applied to the ball by push stick 502. In this way, the ball can be launched at different speeds depending on the amount of pushing force.

[0027] Working Principle: First, start motor 601. Starting motor 601 drives the lead screw 604 to rotate. The rotation of lead screw 604 then drives lead screw slider 609 to move backward. This backward movement of lead screw slider 609 drives the iron lever 608 to move backward. The iron lever 608 then moves the sliding foot 504 backward, causing the energy storage spring 506 to store energy. By controlling the stroke of lead screw slider 609, the compression degree of the energy storage spring 506 is adjusted, thereby adjusting the pushing force of the push rod 502, causing the ball to be launched at different speeds. After the energy storage spring 506 has fully stored energy, electromagnet 607 can be turned off. Turning off electromagnet 607 releases the iron lever 608, and the sliding foot 504 will then be unobstructed. At this time, the energy storage spring 506 will be released. After the energy storage spring 506 is released, it will push the push stick 502 to move forward quickly and hit the ball in the push plate 3, so that the ball in the push plate 3 will be shot towards the goal from a distance. The goal can be completed without the robot car 1 moving to the goal, which greatly improves the efficiency of the goal-scoring task.
