[0020] 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.
[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] like Figures 1 to 5As shown, the snake-like robot walking structure in this embodiment includes a first moving module 1 on the far left and a second moving module 4 on the far right. The first moving module 1 and the second moving module 4 function as movement modules. It should be noted that users can install other external structures on the outside of the first moving module 1 and the second moving module 4 as needed. Three rotating modules 2 are installed at one end of the first moving module 1. These three rotating modules 2 do not contact each other and function as rotation modules. The rotation direction of the rotating modules 2 is perpendicular to the movement direction of the first moving module 1 and the second moving module 4. Two rotating modules are installed between two adjacent rotating modules 2. The steering module 3 and any adjacent module can rotate at a certain angle to meet the turning requirements of the snake robot. A second moving module 4 is installed at the right end of the rightmost rotating module 2. Multiple through holes 20 are formed on the surfaces of both the first moving module 1 and the second moving module 4. Each through hole 20 is rotatably connected to a moving wheel 5. The moving wheels 5 are divided into two groups, located on the left and right sides of either the first moving module 1 or the second moving module 4. Cavities are formed inside the first moving module 1, the second moving module 4, the steering module 3, and the rotating module 2. Any two sets of moving wheels 5 on the surface of module 1 or the second moving module 4 can rotate, thereby driving the snake robot to move. The first moving module 1 or the second moving module 4 is located on the left and right sides of the snake robot, allowing the snake robot to move arbitrarily in two directions, increasing the robot's versatility. Multiple rotating modules 2 installed between the first moving module 1 or the second moving module 4 can make the snake robot roll on the ground. The steering module 3, rotating module 2, first moving module 1 and second moving module 4 work together to enable the snake robot to move forward and backward, roll and turn on different terrain surfaces, making it more flexible and versatile. It should be noted that the outermost edge of the moving wheel 5 is flush with the outermost edge of the rotating module 2, so that when the moving wheel 5 rotates, the outermost edge of the rotating module 2 is in contact with the ground, and when the rotating module 2 rotates, the moving wheel 5 is also in contact with the ground. There is a certain degree of mutual influence between them. An external control program is needed to control the moving wheel 5, rotating module 2 and steering module 3 to work together to further reduce mutual interference and influence. It should be noted that each steering module 3 has a detachable mobile power supply installed inside to provide power support for the snake robot.
[0023] Specifically, each movable wheel 5 has a first helical gear 6 installed on both sides. A second helical gear 7 is meshed with the outer side of any one of the first helical gears 6. A rotating shaft 8 is installed at the end of each of the second helical gears 7 away from the movable wheel 5. A driven gear 9 is installed at the other end of the rotating shaft 8. A driving gear 10 is meshed with the inner side of the driven gears 9. A second drive device 12 is installed at the end of the driving gear 10 away from the movable wheel 5. The second drive device 12 can drive the driving gear 10 to rotate. The driving gear 10 drives the driven gears 9 to rotate. The driven gears 9 drive the second helical gears 7 to rotate. The second helical gears 7 drive the first helical gears 6 to rotate. The first helical gears 6 will rotate synchronously with the movable wheel 5. It should be noted that each second helical gear 7 only meshes with one first helical gear 6. Therefore, the multiple second helical gears 7 will rotate in the same direction under the influence of the driving gear 10. The multiple first helical gears 6 and the movable wheel 5 will also rotate in the same direction under the influence of the second helical gears 7.
[0024] Furthermore, the driven gear 9 is rotatably connected to a support shaft at the end away from the moving wheel 5, and a support disc 13 is mounted on the other end of multiple support shafts 11. The side of the support disc 13 is fixedly connected to the inner wall of the first moving module 1 or the second moving module 4, and the end of the support disc 13 near the moving wheel 5 is connected to the second drive device 12. The support disc 13 is fixedly connected to the inner wall of the first moving module 1 or the second moving module 4, and at the same time provides support for the second drive device 12, multiple support shafts 11 and driven gear 9.
[0025] Furthermore, two second mounting plates 17 are symmetrically installed on the left ends of both the steering module 3 and the rotation module 2, and two first mounting plates 16 are symmetrically installed on the right ends of both the steering module 3 and the rotation module 2. A third drive device 15 is installed on the upper end of the lower first mounting plate 16. A main shaft 18 is installed at both the upper and lower ends of the third drive device 15. The two main shafts 18 pass through the second mounting plate 17 and the first mounting plate 16 in sequence. The surface of the first mounting plate 16 has through holes 20, and the surface of the second mounting plate 17 has slots 19. Two locking blocks 21 are symmetrically installed on both sides of the main shafts 18. The height of the locking blocks 21 is the same as the thickness of the second mounting plate 17. The two locking blocks 21 and the slots 19 When used in conjunction with each other, during installation, the main shafts 18 at the upper and lower ends of the third drive device 15 are sequentially inserted into the interior of the second mounting plate 17 and the first mounting plate 16. When the main shaft 18 passes through the second mounting plate 17, the locking blocks 21 on both sides of the main shaft 18 will engage with the locking grooves 19 opened on the surface of the second mounting plate 17. The end of the main shaft 18 will be rotatably connected to the through hole 20 on the surface of the first mounting plate 16. This allows the third drive device 15 to drive the two main shafts 18 to rotate, thereby driving the two second mounting plates 17 and other modules connected to the second mounting plates 17 to rotate, while the modules connected to the first mounting plate 16 will not rotate, thus completing the steering function between the two different modules.
[0026] Furthermore, the rotating module 2 includes a rotating ring 201, a first connecting module 202, a second connecting module 203, an annular groove 204, a first driving device 205, an annular slider 206, and a connecting disk 207. Two second mounting plates 17 are installed on the left side of the first connecting module 202 and connected to a steering module 3. Two first mounting plates 16 are installed on the right side of the second connecting module 203 and connected to another steering module 3. An annular groove 204 is provided on the right side of the first connecting module 202 and the left side of the second connecting module 203. A rotating ring 201 is rotatably connected to the inner sides of the first connecting module 202 and the second connecting module 203. An annular slider 206 matching the annular groove 204 is installed on both the left and right sides of the rotating ring 201. A connecting disk 207 is fixedly installed on the inner side of the rotating ring 201. A first driving device 205 is installed on one side of the connecting disk 207. The first driving device 205 is fixedly installed inside the first connecting module 202. The first driving device 205 is fixed under the support of the connecting disk 207. The first driving device 205 drives the connecting disk 207 to rotate, and the connecting disk 207 drives the rotating ring 201 to rotate. The rotating ring 201 is rotatably connected to the first connecting module 202 and the second connecting module 203 through the annular sliders 206 installed on the left and right sides, so that when the rotating ring 201 rotates, the first connecting module 202 and the second connecting module 203 will not rotate synchronously. The first moving module 1, the second moving module 4, the steering module 3 and the rotating module 2 are all equipped with annular arc-shaped protective plates 14 on both sides. The arc-shaped protective plates 14 can reduce the impact of complex underground conditions on the internal modules of the snake robot to a certain extent.
[0027] The usage method of this embodiment is as follows: During installation, the main shafts 18 at both ends of the third drive device 15 are sequentially inserted into the interiors of the second mounting plate 17 and the first mounting plate 16. When the main shaft 18 passes through the second mounting plate 17, the locking blocks 21 on both sides of the main shaft 18 will engage with the slots 19 opened on the surface of the second mounting plate 17. The end of the main shaft 18 will be rotatably connected to the through hole 20 on the surface of the first mounting plate 16. This allows the third drive device 15 to drive the two main shafts 18 to rotate, which in turn drives the two second mounting plates 17 and other modules connected to the second mounting plates 17 to rotate. However, the modules connected to the first mounting plate 16 will not rotate, thus completing the steering function between the two different modules. This is achieved through the openings on the surfaces of the first moving module 1 and the second moving module 4. Multiple through holes 20 are provided, and movable wheels 5 are rotatably connected inside the through holes 20. The movable wheels 5 can rotate inside the through holes 20 under the action of external force. Two sets of movable wheels 5 are installed on the surfaces of the first moving module 1 and the second moving module 4, which can drive the snake robot to move in any direction in the forward and backward direction. The rotating module 2 installed between the first moving module 1 and the second moving module 4 can drive the snake robot to roll on the ground. Multiple steering modules 3 can meet the steering needs between multiple different modules of the snake robot. The steering module 3, rotating module 2, first moving module 1 and second moving module 4 work together to enable the snake robot to move forward and backward, roll and turn on different terrain surfaces, making it more flexible and versatile.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
