Description

Technical Field

[0001] The present invention relates to the technical field of transport robots, and in particular to a multi-terrain transport robot. Background Art

[0002] In today's logistics transportation and special operation scenarios, there are many complex terrain and environmental challenges. Traditional means of transportation are often limited to specific terrain conditions. For example, wheeled vehicles are easily trapped in soft or uneven ground such as sand and mud, making it difficult to pass smoothly, resulting in low transportation efficiency or even failure to complete the task. In terms of water transportation, ordinary land transportation tools are completely unable to get involved, and special water transportation equipment is required for transfer, which not only increases transportation costs, but also prolongs transportation time. With the development of science and technology, the demand for intelligent transportation equipment is growing. In some special operation scenarios, such as field rescue operations, it is necessary to quickly transport relief supplies, medical equipment, etc. to the disaster-stricken areas, and the terrain in these areas is often complex and diverse, and may include mountains, rivers, swamps, etc. In the field of scientific research and investigation, equipment that can transport scientific research instruments and samples under various extreme terrain conditions is also needed to conduct data collection and research in inaccessible areas; In order to overcome the limitations of existing transportation tools and meet the transportation needs of multiple scenarios and multiple terrains, multi-terrain transport robots have emerged.

[0011] Beneficial effects: The robot can freely shuttle through various complex terrains such as sand, grass, and uneven ground through a unique transmission structure, that is, the coordinated work of multiple double-headed rotating columns, toothed front wheels, and tracks. The flexible rotation of the double-headed rotating columns can automatically adjust the posture of the wheels according to changes in the terrain. The tracks increase the contact area with the ground, disperse the pressure, and reduce the risk of sinking. The toothed front wheels assist in steering and stable forward movement. Whether it is soft sand or bumpy grass, it can ensure stable travel, greatly broadening the scope of transportation operations, improving the versatility of robots in different geographical environments, reducing dependence on specific terrain transportation equipment, and effectively improving overall transportation efficiency and flexibility; When encountering shallow water or muddy ground, the robot exhibits powerful amphibious characteristics. The float and related structures play a key role. The air pump inside the float can be automatically started according to the water level, pushing the unfolded plate to increase buoyancy. At the same time, the float in the float chamber can control the start and limit of the propeller, so that the robot can obtain additional propulsion and lift on the water. This amphibious capability not only allows the robot to overcome obstacles on land and water, but also plays an important role in some special scenarios such as flood disaster relief and wetland material transportation, reducing the transit links in the transportation process and speeding up the transportation. When driving in waters, the smart camera can still continuously monitor the surrounding environment to ensure transportation safety, truly realizing seamless transportation operations in multiple scenarios. The sealing design of the cargo chamber provides reliable protection for the transported goods. The close fit between the sealing groove and the sealing block, plus the snap-fit ​​connection between the upper cover and the cargo chamber, builds a tight protective barrier that effectively blocks dust, moisture and other impurities from the outside. When transporting precision instruments, electronic equipment and other items that have strict environmental requirements, it can maintain a stable, clean and dry internal environment to prevent damage or performance degradation of the goods due to moisture, dust and other factors. The expansion plate inside the float not only enhances the robot's buoyancy and stability in the water, but also indirectly protects the goods. When the robot enters the water environment, the expansion plate can prevent the device from wading too deep, which makes the robot more stable when driving on the water, reducing the risk of impact and displacement of the goods in the cargo chamber caused by shaking and bumps.

DETAILED DESCRIPTION

[0014] 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. Example

[0015] like Figure 1-10 As shown, a multi-terrain transport robot is provided, including a base 1, a groove 2 is provided inside the base 1, a plurality of double-headed rotating columns 3 are symmetrically rotated and connected, the double-headed rotating columns 3 include a front rotating column 101, a rear end of the front rotating column 101 is rotatably connected to a rotating rod 102, a rear end of the rotating rod 102 is rotatably connected to a rear rotating column 103, one end of the front rotating column 101 and the rear rotating column 103 away from the rotating rod 102 are both penetrated to the outer wall of the base 1, and are fixedly connected to a rotating wheel 104, the outer wall of the rotating wheel 104 is provided with a linkage tooth 105, the outer wall of the front rotating column 101 and the outer wall of the rear rotating column 103 are both fixedly connected to a gear 106, The gears 106 are rotatably connected to the inner side walls of the grooves 2 respectively, a transmission device 4 is fixedly connected to the right side of the inner lower surface of the groove 2, both ends of the transmission device 4 are fixedly connected to transmission teeth 5, adjacent transmission teeth 5 and the outer side walls of the gears 106 are jointly provided with a transmission chain 7, the right side of the outer side wall of the base 1 is symmetrically rotatably connected to a toothed front wheel 8, the adjacent toothed front wheel 8 and the outer side wall of the linkage gear 105 are jointly provided with a circle of crawler tracks 10, the upper surface of the base 1 is fixedly connected to a support plate 18, the upper surface of the support plate 18 is fixedly connected to a floating plate 36, the upper surface of the floating plate 36 is fixedly connected to a loading cavity 37, and the right side of the loading cavity 37 is fixedly connected to a smart camera 50; When the robot is started, the transmission device 4 located on the right side of the lower surface of the inner groove 2 of the base 1 starts to work. The transmission device 4 drives the transmission teeth 5 at both ends to rotate. Since the transmission teeth 5 and the gear 106 are connected by the transmission chain 7, sealing rings are provided at the connection between the transmission chain 7 and the gear 106 and the transmission teeth 5 to prevent water from entering, ensuring that the transmission can still be normal in a humid or watery environment. The gear 106 is fixed on the front rotating column 101 and the rear rotating column 103 respectively, so the rotation of the transmission device 4 will drive the transmission teeth 5, the transmission chain 7, the gear 106 and the double-headed rotating column 3 to rotate in turn. When the double-headed rotating column 3 rotates, the rotating wheels 104 at both ends thereof also rotate accordingly. The linkage teeth 105 on the outer wall of the rotating wheel 104 are connected to the toothed front wheel 8 through the crawler 10. The rotation of the rotating wheel 104 will drive the crawler 10 to operate, realizing the movement of the robot on the ground. During the movement, the robot can rely on its special track 10 and wheel 104 structure to adapt to various terrains, such as sand, grass, uneven ground, etc. When encountering some special terrains, such as shallow water or muddy land, the float 36 can provide a certain buoyancy to assist the robot to pass, ensuring that the cargo chamber 37 and the items inside will not be damaged by contact with water or sinking into mud. The smart camera 50 can monitor the surrounding environment in real time, provide visual information support for the robot's autonomous navigation, obstacle avoidance, and cargo transportation status monitoring, etc., and help the robot accurately complete the transportation task in a complex multi-terrain environment, and safely transport the items in the cargo chamber 37 from the starting point to the designated destination.

[0016] In this embodiment, the transmission device 4 includes a fixed seat 11, an arc-shaped cavity 12 is provided on the upper surface of the fixed seat 11, and a bayonet 13 is symmetrically provided inside the arc-shaped cavity 12, and a circular cavity 14 is connected to the inside of the arc-shaped cavity 12 by snapping, and a clamping block 15 is symmetrically fixedly connected to the outer wall of the circular cavity 14, and the clamping block 15 is snap-connected with the adjacent bayonet 13, and both ends of the circular cavity 14 are provided with a fixed groove 51, and the inside of the fixed groove 51 is fixedly connected with a motor 16, and the output end of the motor 16 is fixedly connected with a transmission column 17, and the outer wall of the transmission column 17 is fixedly connected to the transmission tooth 5; The transmission device 4 includes a fixed seat 11, an arc cavity 12 is provided on the upper surface of the fixed seat 11, a bayonet 13 is symmetrically provided in the arc cavity 12, a circular cavity 14 is engaged and connected in the arc cavity 12, and a block 15 symmetrically fixedly connected to the outer wall of the circular cavity 14 is engaged and connected with the bayonet 13. This structure enables the circular cavity 14 to be stably installed in the arc cavity 12. The motors 16 fixed in the fixed grooves 51 at both ends of the circular cavity 14 can work independently. By controlling the rotation direction and speed of the two motors 16, the rotation direction of the transmission teeth 5 driven by the transmission columns 17 on both sides can be separated, and then the steering and driving actions of the robot can be flexibly controlled. For example, if one motor rotates forward and the other motor rotates reversely, the robot can realize complex actions such as turning in place to adapt to different terrains and transportation task requirements. During the movement, the robot can rely on its special crawler 10 and wheel 104 structure to adapt to various terrains, such as sand, grass, uneven ground, etc.

[0017] In this embodiment, a turning opening 19 is provided on the left side of the support plate 18, and a high-speed motor 20 is fixedly connected to the right side of the inside of the turning opening 19. The left end of the output end of the high-speed motor 20 passes through the outside of the support plate 18 and is fixedly connected to a cross bar 21. The outer wall of the cross bar 21 is located on the left side of the support plate 18 and is fixedly connected to a propeller 22. The outer wall of the cross bar 21 is provided with a plurality of limiting grooves 23. A sliding groove 24 is provided on the lower surface of the inner part of the turning opening 19, and a wedge-shaped slide 25 is slidably connected to the inside of the sliding groove 24. A limiting block 26 is fixedly connected to the upper surface of the wedge-shaped slide 25. A transverse groove 27 is provided on the right side of the sliding groove 24, and an extrusion groove 28 is provided on the right side of the transverse groove 27. , a vertical plate 29 is slidably connected inside the extrusion groove 28, an extrusion strip 30 is fixedly connected to the left side of the vertical plate 29, the left end of the extrusion strip 30 penetrates into the interior of the sliding groove 24, and contacts the lower surface of the wedge-shaped slide plate 25, a plurality of springs 31 are directly fixedly connected to the inner side of the extrusion groove 28 on the right side of the vertical plate 29, a floating cavity 32 is provided on the right side of the support plate 18, an extrusion plate 33 is slidably connected inside the float cavity 32, a float ball 34 is fixedly connected to the lower surface of the extrusion plate 33, a water inlet groove 35 is provided on the right side of the float cavity 32, an air outlet groove 42 is provided on the left side of the float cavity 32, and the end of the air outlet groove 42 away from the float cavity 32 is fixedly connected to the left side of the extrusion groove 28; When the robot needs additional lift assistance or water propulsion under certain circumstances, the high-speed motor 20 starts to work. The high-speed motor 20 drives the crossbar 21 to rotate at high speed, and the propeller 22 on the crossbar 21 rotates accordingly, thereby generating upward lift or forward propulsion, which helps the robot to operate on the water surface or in scenes where the height needs to be increased. During the rotation of the crossbar 21, the limit groove 23 on its outer wall plays a key role. When the robot is in a normal land driving state and the propeller 22 is not needed to work, the float 34 is in a lower position under the action of gravity, driving the squeeze plate 33 to be located at the lower part of the float chamber 32. At this time, the gas in the float chamber 32 is kept in balance with the outside world through the water inlet groove 35, the spring 31 is in a naturally stretched state, the extrusion bar 30 does not squeeze the wedge-shaped slide 25, the wedge-shaped slide 25 is in the initial position in the sliding groove 24, and the limit block 26 above it is stuck in the limit groove 23 of the cross bar 21, limiting the rotation of the cross bar 21, so that the propeller 22 will not rotate accidentally, ensuring the stability and safety of the robot when driving on land. When the robot enters shallow waters or needs the propeller 22 to provide power, water enters the water inlet groove 35, the water level in the float chamber 32 rises, and the float 34 drives the extrusion plate 33 to move upward with the rising water level, pressing the gas in the float chamber 32 into the extrusion groove 28 through the air outlet groove 42. As the gas enters the extrusion groove 28, the gas pressure increases, pushing the vertical plate 29 to move rightward, and the vertical plate 29 drives the extrusion bar 30 to squeeze the wedge-shaped slide plate 25 to the right, so that the wedge-shaped slide plate 25 slides downward in the sliding groove 24, so that the limit block 26 is separated from the limit groove 23 of the crossbar 21, and the restriction on the crossbar 21 is released. At this time, the high-speed motor 20 can smoothly drive the crossbar 21 and the propeller 22 to rotate, providing the robot with the power required for traveling on water.

[0018] In this embodiment, a slide groove 43 is provided inside the floating plate 36, and an expansion plate 44 is symmetrically slidably connected inside the slide groove 43. An air pump 45 is fixedly connected to the right side of the floating plate 36. The output end and the input end of the air pump 45 are both fixedly connected to the inside of the floating plate 36. A pump body start switch 46 is fixedly connected to the inner upper surface of the floating cavity 32. During the operation of the robot, the position of the float 34 in the float chamber 32 will change with the change of the robot's environment. When the robot enters the water area and the water level rises to a certain level, the float 34 will rise accordingly. Once the float 34 rises to touch the pump start switch 46 on the upper surface of the float chamber 32, the pump start switch 46 is closed. This closed signal will start the air pump 45 to start working. When the air pump 45 is running, it inhales air from the outside through its input end and fills the air into the internal space of the float plate 36 through the output end. As the air is continuously filled in, the air pressure inside the float plate 36 gradually increases. Driven by the air pressure, the symmetrical expansion plate 44 originally housed in the slide 43 begins to slide outward along the slide 43 and expand. The expansion of the expansion plate 44 increases the contact area between the float plate 36 and the water surface, thereby significantly improving the buoyancy provided by the float plate 36 and the overall stability of the robot on the water surface. This automatically triggered buoyancy adjustment mechanism enables the robot to operate smoothly in water environments with different water depths and water flow conditions, effectively avoiding situations such as the robot losing balance or even damage to cargo due to insufficient buoyancy or water surface fluctuations, ensuring the safety and reliability of the robot's water transport operations.

[0019] In this embodiment, the loading chamber 37 includes a bottom chamber 38, a sealing groove 47 is formed on the upper surface of the bottom chamber 38, a sealing block 48 is snap-connected inside the sealing groove 47, an upper cover 49 is fixedly connected to the upper surface of the sealing block 48, and the upper cover 49 is snap-connected to the loading chamber 37 through a snap-connecting device; When it is necessary to load goods, first open the upper cover 49 and the cargo chamber 37 through the snap-fit ​​device, and at this time, the sealing block 48 is opened together with the upper cover 49 to expose the bottom chamber 38. After placing the goods inside the bottom chamber 38, put the upper cover 49 back on the cargo chamber 37. During the covering process, the sealing block 48 is accurately inserted into the sealing groove 47 to form a tight sealing connection. This sealing structure can effectively prevent external dust, moisture and other impurities from entering the cargo chamber 37, ensuring the safety and integrity of the loaded goods. For example, when transporting some items with high environmental requirements, such as precision instruments, electronic equipment or goods that are easily affected by moisture, the sealed cargo chamber can provide them with a relatively stable, clean and dry storage environment, avoiding damage or performance degradation of the goods due to external factors, ensuring the smooth progress of the transportation task and the quality of the goods.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
