Description

Technical Field

[0001] The invention relates to the technical field of robots, and in particular to an amphibious robot mobile seat. Background Art

[0002] With the development of science and technology, robotics has been widely used in many fields, but most traditional robots are only applicable to a single land or water environment and are difficult to meet the increasingly complex real-world needs. In many practical scenarios, such as flood relief, ocean exploration, amphibious ecological monitoring, and amphibious border patrols, robots are required to have the ability to flexibly switch between land and water. However, some existing so-called "amphibious robots" face many problems in realizing amphibious functions, such as the power conversion between land and water is not smooth enough, the power system is complex and inefficient, resulting in poor movement speed and maneuverability of the robot in different environments. At the same time, for the steering system of amphibious robots, traditional designs are often not accurate and flexible enough, and it is difficult to achieve precise steering control, which affects the robot's navigation ability in complex terrain and water flow. Moreover, during the steering process, due to the lack of effective sealing measures, dust, water or other impurities are easily introduced into key components, affecting the reliability and stability of the steering system, thereby shortening the service life of the robot and increasing maintenance costs;

[0003] Therefore, for the overall design of amphibious robots, existing technologies usually ignore the integration of environmental perception and system protection, making it difficult for the robot to effectively perceive the surrounding environment and provide good protection for its key components during the water-land transition process. Therefore, there is an urgent need for an amphibious robot mobile seat with a more optimized structure and more complete functions to overcome the above problems and achieve better amphibious performance, steering control and sealing protection.

[0014] Beneficial effects: The device exhibits excellent amphibious performance. In a terrestrial environment, the motor 1 in the power chamber serves as a power source, and its output end is connected to a linkage rod, which in turn drives the toothed drum to rotate. The toothed drum cooperates with the rack on the inside of the transmission belt and the toothed groove on the outside of the rotating column to transmit power to the rotating column, and finally rotates the power rear wheel, providing stable forward and backward power for the robot on land. This land mobility allows the robot to easily cross different terrains, such as flat roads, rough sand, rugged mountain roads, etc., and is suitable for many tasks such as land transportation, inspection, and surveying. When entering the water, the motor 2 of the underwater power module starts to work, and its output end drives the power rod to rotate, and through the meshing transmission of the transmission bevel gear and the wedge-shaped right gear and the wedge-shaped left gear, the power propeller on the transmission crossbar starts to rotate. The water flow thrust generated by the power propeller drives the robot to sail freely in the water, realizing the efficient movement of the robot in the water. This amphibious performance enables the robot to switch freely between two completely different environments, water and land, greatly expanding the robot's operating range. For example, it plays an important role in complex tasks such as amphibious ecological environment monitoring and disaster relief, and enhances the robot's mission adaptability and versatility.

[0015] In terms of steering, the electric telescopic rod pushes the squeeze plate to slide in the squeeze chamber, changing the gas pressure in the squeeze chamber. The gas is transmitted to the sliding chamber through the connecting pipe, pushing the sliding plate, and driving the vertical rod to slide in the telescopic chamber through the L-shaped connecting plate and the sliding mouth, thereby realizing the steering operation of the steering wheel. This steering system has a compact structure and good response speed, which allows the robot to quickly adjust the direction of travel under various circumstances and improve maneuverability. In order to ensure the reliability and stability of the steering system, the steering system is equipped with multiple sealing components. The sealing ring on the outer wall of the vertical rod plays a key role. During the sliding process of the vertical rod, it can effectively prevent gas leakage and prevent external dust and impurities from entering the telescopic chamber, ensuring the cleanliness of the steering system and the stability of the air pressure. In water, the waterproof pad on the outer wall of the horizontal column can prevent water from entering the horizontal groove when the horizontal column rotates, ensuring that the key components such as the motor 2 and the transmission bevel gear in the underwater power module are not corroded by water, and ensuring the normal operation of the entire power system when the base is steering in water. This sealing performance enhances the durability and stability of the system, allowing the base to maintain a good working condition during long-term use and reducing the risk of failure caused by sealing problems.

[0028] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 1-11 As shown, an amphibious robot mobile seat is provided, including a body 1, a power chamber 2 is opened on the left side of the body 1, a rotation groove 3 is symmetrically opened inside the power chamber 2, a rotation column 4 is rotatably connected inside the rotation groove 3, a toothed groove 5 is opened on the outer wall of the rotation column 4, and a motor 16 is fixedly connected to the inner rear surface of the power chamber 2, a linkage rod 7 is fixedly connected to the output end of the motor 16, a toothed drum 8 is fixedly connected to the outer wall of the linkage rod 7, a transmission belt 9 is arranged on the outer wall between the toothed groove 5 and the toothed drum 8, a rack 10 is opened on the inner wall of the transmission belt 9, and the rack 10 is meshed and connected with the outer wall of the toothed groove 5 and the toothed drum 8, both ends of the rotation column 4 extend to the outer wall of the power chamber 2, and are fixedly connected with a power rear wheel 11, a steering wheel 12 is symmetrically arranged on the outer wall of the body 1, and a sealing gasket 43 is fixedly connected to the outer wall of the rotation column 4, which is located inside the power chamber 2;

[0031] The robot can be installed on the upper surface of the body 1. When the start command is received, the motor 6 starts to work, and its output end drives the linkage rod 7 to rotate, and the toothed drum 8 connected thereto rotates accordingly. When the toothed drum 8 rotates, it meshes with the rack 10 on the inner side of the transmission belt 9. Since the rack 10 of the transmission belt 9 also meshes with the toothed groove 5 on the outer wall of the rotating column 4, the rotating column 4 is driven to rotate in the rotating groove 3, and then the power rear wheels 11 at both ends of the rotating column 4 rotate, providing the robot with power to move forward or backward, and driving the robot to move. The sealing gasket 43 on the outer wall of the rotating column 4 is located in the power cavity 2. During the rotation of the rotating column 4, the sealing gasket 43 can prevent impurities such as water and dust from entering the power cavity 2, ensuring the normal operation of the internal motor 6, linkage rod 7, toothed drum 8 and other components, and ensuring the stability of power transmission. According to the needs, the steering wheel 12 is controlled. By adjusting the angle of the steering wheel 12 and combining the drive of the power rear wheel 11, the robot can move flexibly in different environments.

[0032] In this embodiment, the outer wall of the body 1 is symmetrically fixedly connected with a fixed plate 47, the outer wall of the fixed plate 47 is symmetrically fixedly connected with a rotating block 13, the outer wall of the rotating block 13 is rotatably connected with a rotating plate 14 with a hole, the front surface of the rotating plate 14 with a hole is commonly fixedly connected with a vertical plate 15, the front surface of the vertical plate 15 is fixedly connected with a short column 16, the opposite ends of the short column 16 are fixedly connected with the steering wheel 12, a steering cavity 17 is opened on the right side of the body 1, a telescopic cavity 18 is opened on the left side of the steering cavity 17, the interior of the telescopic cavity 18 is slidably connected with a vertical rod 48, an air squeezing cavity 19 is opened on the right side of the steering cavity 17, the interior of the air squeezing cavity 19 is slidably connected with an air squeezing plate 20, the rear surface of the air squeezing plate 20 is fixedly connected with an electric telescopic rod 21, the rear surface of the electric telescopic rod 21 is fixedly connected to the inner rear surface of the steering cavity 17, and the air squeezing cavity The left side of 19 is fixedly connected with a sliding cavity 22, and a sliding plate 49 is slidably connected inside the sliding cavity 22. An L-shaped connecting plate 50 is fixedly connected to the front surface of the sliding plate 49. A sliding opening 51 is fixedly connected between the steering cavity 17 and the telescopic cavity 18. One end of the L-shaped connecting plate 50 away from the sliding plate 49 passes through the sliding opening 51 and is fixedly connected to the right side of the vertical rod 48. A connecting pipe 23 is fixedly connected between the squeezing cavity 19 and the sliding cavity 22. Short plates 24 are fixedly connected to the opposite ends of the vertical rod 48. Short rotating columns 25 are symmetrically fixedly connected to the outer side walls of the short plates 24. Straight plates 26 with holes are rotatably connected to the outer side walls of the short rotating columns 25. The opposite ends of the straight plates 26 with holes are fixedly connected to the vertical plates 27. The opposite ends of the vertical plates 27 are fixedly connected to the opposite sides of the adjacent steering wheels 12. Sealing rings 56 are symmetrically fixedly connected to the outer side walls of the vertical rods 48.

[0033] When steering is required, the electric telescopic rod 21 is started, which pushes the squeezing plate 20 to slide in the squeezing chamber 19. The forward and backward movement of the squeezing plate 20 will change the gas pressure in the squeezing chamber 19. The gas in the squeezing chamber 19 can transfer the pressure to the sliding chamber 22 through the connecting pipe 23. Under the action of pressure, the sliding plate 49 in the sliding chamber 22 drives the L-shaped connecting plate 50 to move, and the L-shaped connecting plate 50 drives the vertical rod 48 to slide in the telescopic chamber 18 through the sliding mouth 51. The movement of the vertical rod 48 is transmitted through the short plates 24 at both ends. The short rotating column 25 on the outer wall of the short plate 24 is rotatably connected to the straight plate 26 with holes, and the straight plate 26 with holes is connected to the vertical plate 27, and the vertical plate 27 is fixedly connected to the opposite side of the steering wheel 12. When the vertical rod 48 moves, the angle of the steering wheel 12 is changed through the linkage of the above-mentioned connecting components to achieve the steering function. The sealing ring 56 on the outer wall of the vertical rod 48 plays a sealing role during the sliding process of the vertical rod 48, preventing gas leakage and external impurities from entering the telescopic chamber 18, thereby ensuring the stable and reliable operation of the steering system. In summary, the structure pushes the air extrusion plate 20 through the electric telescopic rod 21, utilizes gas pressure transmission to move the vertical rod 48, and then drives the steering wheel 12 to rotate to realize the steering function. The sealing ring 56 ensures the sealing of the system.

[0034] In this embodiment, a groove 28 is provided on the left side of the body 1, and an underwater power module 29 is fixedly connected inside the groove 28. A transverse groove 30 is provided on the left side of the underwater power module 29. A transverse column 31 is rotatably connected to the right side of the transverse groove 30. A wedge-shaped right gear 32 is fixedly connected to the left side of the wedge-shaped right gear 32 at the left end of the transverse column 31. A wedge-shaped left gear 56 is fixedly connected to the left end of the extension column 33. A motor cavity 52 is provided on the upper surface of the interior of the transverse groove 30. A motor 53 is fixedly connected to the upper surface of the interior of the motor cavity 52. The bottom end of the output end of the motor 2 53 is fixedly connected with a power rod 54, the bottom end of the power rod 54 penetrates into the interior of the horizontal groove 30, and is fixedly connected with a transmission bevel gear 55, the transmission bevel gear 55 is meshed with the wedge-shaped right gear 32 and the wedge-shaped left gear 56, the left side of the wedge-shaped left gear 56 is fixedly connected with a transmission cross bar 34, the outer side wall of the transmission cross bar 34, located on the left side of the underwater power module 29, is fixedly connected with a power propeller 35, the inner side wall of the horizontal groove 30 is provided with a waterproof groove 44 on the left side, and the outer side wall of the horizontal column 31, located inside the waterproof groove 44, is rotatably connected with a waterproof pad 45;

[0035] When the robot needs to move in the water, the second motor 53 starts to work. The second motor 53 is fixed to the inner upper surface of the motor cavity 52. ​​After it is started, it will drive the power rod 54 to rotate. The power rod 54 penetrates into the interior of the horizontal groove 30, and the transmission bevel gear 55 fixedly connected at its bottom end rotates accordingly. The transmission bevel gear 55 is meshed with the wedge-shaped right gear 32 and the wedge-shaped left gear 56. Therefore, when the transmission bevel gear 55 rotates, the wedge-shaped right gear 32 and the wedge-shaped left gear 56 will be driven to rotate. Since the wedge-shaped right gear 32 and the wedge-shaped left gear 56 are connected by the extension column 33, they will rotate synchronously, and the transmission cross bar 34 fixedly connected to the left side of the wedge-shaped left gear 56 will rotate with the rotation of the wedge-shaped left gear 56, and the power propeller 35 fixedly connected to the outer wall of the transmission cross bar 34 will rotate accordingly. The rotation of the power propeller 35 will generate water thrust, pushing the amphibious robot forward or backward in the water, and providing power for the robot to move in the water. During the rotation of the horizontal column 31, in order to prevent water from entering the horizontal groove 30, the outer wall of the horizontal column 31 is located in the waterproof groove 44 and is rotatably connected to a waterproof pad 45. The waterproof pad 45 can play a good sealing and waterproof role, ensuring that key components such as the motor 2 53 and the transmission bevel gear 55 in the underwater power module 29 will not be corroded by water, thereby ensuring the normal operation and life of the underwater power module 29. In summary, the underwater power module 29 of the amphibious robot drives the power rod 54 and the transmission bevel gear 55 through the motor 2 53, and uses the gear meshing to drive the wedge-shaped right gear 32 and the wedge-shaped left gear 56 to rotate, thereby driving the transmission cross bar 34 and the power propeller 35 to rotate. At the same time, the waterproof pad 45 provides it with waterproof protection, so that the robot can move normally in the water.

[0036] In this embodiment, a floating groove 36 is provided on the right side of the inner part of the underwater power module 29, a floating plate 37 is slidably connected to the inner part of the floating groove 36, a contact point 38 is fixedly connected to the upper surface of the floating plate 37, a switch groove 39 is provided on the inner upper surface of the floating groove 36, a contact switch 40 is fixedly connected to the inner upper surface of the switch groove 39, a reset spring rod 41 is symmetrically fixedly connected to the upper surface of the floating plate 37, the top of the reset spring rod 41 is fixedly connected to the inner upper surface of the floating groove 36, and the outer wall of the floating groove 36 is symmetrically fixedly connected to the water inlet pipe 42, and the water inlet pipe 42 passes through the outer wall of the body 1;

[0037] When the amphibious robot enters the water, water will enter the float groove 36 through the water inlet pipe 42. The water inlet pipe 42 penetrates the outer wall of the body 1 so that water can flow smoothly into the float groove 36. As the water flows in, the float plate 37 will be affected by the buoyancy of the water. According to the Archimedes principle, the buoyancy of the float plate 37 is equal to the gravity of the liquid it displaces. When the buoyancy of the float plate 37 is large enough, it will slide upward. The float plate 37 moves upward in the float groove 36, and the contact point 38 on its upper surface will gradually approach and eventually contact the contact switch 40 in the switch groove 39. Once the contact point 38 contacts the contact switch 40, the contact switch 40 will be triggered. The contact switch 40 can be used as a control signal, for example, to control the start-up of the underwater power module 29 or other related operations to adapt to the state of the robot in the water. When the robot leaves the water, the float plate 37 will reset under the elastic force of the reset spring rod 41 and return to the initial position. The reset spring rod 41 serves to pull the float 37 back to its initial position, and at the same time separates the contact point 38 from the contact switch 40. The contact switch 40 will return to an untriggered state and be ready for the next trigger. In summary, the water inlet pipe 42 allows water to enter the float tank 36, and the float 37 slides up and down under the influence of buoyancy. When the buoyancy is large, the contact point 38 triggers the contact switch 40, and the reset spring rod 41 resets the float 37. This structure can realize the perception of the robot's state in water and related control operations.

[0038] In this embodiment, the steering wheel 12 includes a disc 101, a circular groove 102 is formed on the outer wall of the disc 101, a rotating circle 103 is provided on the outer wall of the circular groove 102, a limited rotation bar 104 is fixedly connected to the inner wall of the rotating circle 103, and the limited rotation bar 104 is rotatably connected to the circular groove 102;

[0039] The steering wheel 12 includes a disc 101, which is the main part of the steering wheel. A circular groove 102 is provided on the outer wall of the disc 101, which provides space for the installation and rotation of subsequent components. A rotating circle 103 is provided on the outer wall of the circular groove 102, and the rotating circle 103 can rotate relative to the disc 101 to realize the steering function of the steering wheel. The inner wall of the rotating circle 103 is fixedly connected to a limited rotation bar 104, and the limited rotation bar 104 is rotatably connected to the circular groove 102. The limiting rotating bar 104 plays a limiting role, which makes the rotation of the rotating circle 103 in the circular groove 102 more stable and orderly, avoids unnecessary displacement or shaking of the rotating circle 103, ensures that the rotating circle 103 can only rotate on a predetermined rotation path, and ensures that the steering operation of the steering wheel has good accuracy and reliability. In summary, the steering wheel 12 provides an installation and rotation space for the rotating circle 103 through the circular groove 102 on the disc 101, and the rotating circle 103 rotates stably in the circular groove 102 under the limiting action of the limiting rotating bar 104, thereby realizing the steering function of the steering wheel.

[0040] In this embodiment, a pathfinder camera 46 is fixedly connected to the right side of the upper surface of the body 1;

[0041] The main function of the pathfinder camera 46 is to provide visual information for the amphibious robot and help the robot observe the surrounding terrain and obstacles in different environments. During the movement of the robot, the pathfinder camera 46 can transmit the captured images and video information to the robot's control system. The control system plans the robot's route by analyzing and processing this information, avoiding collisions with obstacles, or finding a better path. For example, on land, it can help the robot avoid obstacles such as stones and potholes on the ground; in water, it can detect objects such as reefs and water plants in the water that may hinder the robot's progress, so that the robot can complete the task more safely and efficiently. In summary, the pathfinder camera 46 is installed on the right side of the upper surface of the body 1 to provide visual information for the robot's navigation and obstacle avoidance, and to assist the robot in path planning and safe movement.
