[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] Mars rover training aids, such as Figure 1 As shown, the teaching aid includes a frame 1, with a carrying bucket 11 fixedly connected to the top of the frame 1. The carrying bucket 11 can hold items or carry people, providing the teaching aid with a certain storage space. A walking module 2 is fixedly connected to the bottom of the frame 1. The walking module 2 adopts a symmetrical structure and is used to drive the frame 1 to move. Drive modules 3 are installed on both sides of the walking module 2 to drive the walking module 2 to move and turn. The above structure is the basic structure of the teaching aid, which is used to ensure that the teaching aid has complete walking and turning capabilities.
[0028] like Figure 5 As shown, the frame 1 includes an adjusting rod 12 and a "U"-shaped support rod 13. The two ends of the adjusting rod 12 are connected to a steering rod 14 through an angle adjustment seat 4. The end of the steering rod 14 away from the adjusting rod 12 is connected to the support rod 13 through the angle adjustment seat 4. When the Mars rover teaching aid turns, this setting allows the adjusting rod 12 to turn with the wheels, thereby reducing the overall movement of the frame 1 during the turning process and improving the stability of the teaching aid when turning.
[0029] like Figure 1 As shown, a control module 17 is fixedly connected to the support rod 13, and a battery module 18 is fixedly connected to the adjustment rod 12. The control module 17 adopts a combination of buttons and a screen. The button settings can more accurately and timely provide feedback on the status of the teaching aid to the operator during operation. The screen is used to allow the operator to obtain the status of the teaching aid, such as the power level, to ensure the operability and interactivity of the teaching aid. The battery module 18 is used to provide power to the drive module 3, ensuring that the drive module 3 has enough power to drive the teaching aid to move.
[0030] like Figures 2 to 4 as well as Figure 6As shown, the walking module 2 includes a main shaft 21 fixedly connected to the frame 1. First wheel rods 22 are fixedly connected to both sides of the main shaft 21. The two ends of the first wheel rods 22 are connected to a second wheel rod 23 and a third wheel rod 24 respectively via angle adjustment seats 4. The main shaft 21 connects the wheel rods on both sides to form a whole, thereby strengthening the overall integrity of the walking module 2 and making the structure of the walking module 2 more stable during use, ensuring the structural strength of the walking module 2. Simultaneously, the angle adjustment seats 4 between the wheel rods allow for relative rotation of parts of the walking module 2, ensuring that the teaching aid remains parallel to the ground on slopes or uneven terrain, thus ensuring the stability of the Mars rover teaching aid when used on such terrain. A rear wheel 25, a middle wheel 26, and a front wheel 27 are rotatably connected to the first wheel rod 22, the second wheel rod 23, and the third wheel rod 24 respectively.
[0031] like Figure 1 and Figure 5 As shown, shaft joints 16 are symmetrically arranged below the support rod 13. The main shaft 21 passes through the shaft joints 16. A double bearing seat 225 is fixedly connected to the first wheel rod 22. Both ends of the main shaft 21 are rotatably connected to the double bearing seats 225 on both sides. The shaft joints 16 and double bearing seats 225 are used to strengthen the connection between the main shaft 21 and the frame 1 and between the main shaft 21 and the first wheel rod 22, respectively, so as to further strengthen the overall integrity of the teaching aid.
[0032] like Figure 2 and Figure 6 As shown, the ends of the first wheel rod 22 and the third wheel rod 24 away from the second wheel rod 23 are both fixedly connected to a rotating seat 28. The drive module 3 includes a steering servo motor 31, the output shaft of which is fixedly connected to the bottom of the rotating seat 28. By setting motors on the four wheels, the front wheel 27 and the rear wheel 25 have steering capabilities, making the steering function of the teaching aid more flexible. The servo motor allows for precise control of the steering angle of the teaching aid. A first drive servo motor 32 is fixedly connected to the steering servo motor 31, and the output end of the first drive servo motor 32 is fixedly connected to the front wheel 27 or the rear wheel 25. As can be seen from this setting, the front wheel 27 and the rear wheel 25 are both driven by the first drive servo motor 32, while the steering servo motor 31 is only responsible for the steering of the wheels. This allows the drive module 3 to provide strong power for both the steering and movement of the wheels. At the same time, this setting also allows the wheels to have a larger steering range, and the maximum range can achieve the effect of the teaching aid turning around on the spot.
[0033] like Figure 6As shown, the second wheel rod 23 is fixedly connected to the motor frame 231. The drive module 3 also includes a second drive servo motor 33, which is mounted on the motor frame 231. The output end of the second drive servo motor 33 is fixedly connected to the middle wheel 26. The middle wheel 26 is driven by the second drive servo motor 33 alone. Since the middle wheel 26 does not need to have a steering function and is equipped with a motor frame 231, the second drive servo motor 33 can use a more powerful motor, thereby enabling the teaching aid to obtain greater power and thus enabling the teaching aid to cope with terrains that require greater power, such as slopes.
[0034] like Figure 2 , Figure 3 and Figure 6 As shown, a connecting seat 232 is fixedly connected to the second wheel rod 23, and a rotating platform 233 is rotatably connected to the connecting seat 232. The rotating platform 233 is connected to the first wheel rod 22 through an angle adjustment seat 4. This configuration is a specific way of connecting the first wheel rod 22 and the second wheel rod 23. This method allows the first wheel rod 22 and the second wheel rod 23 to obtain a larger range of rotation, thereby being able to cope with more complex terrain with unevenness. In addition, the angle adjustment seat 4 can also provide feedback to the user during the assembly process of the teaching aid, thereby making the assembly process of the teaching aid faster.
[0035] like Figure 1 , Figure 4 and Figure 5 As shown, a connecting rod 15 is fixedly connected to the lower part of the adjusting rod 12. A balance seat 221 is provided on the inner side of the first wheel rod 22. A secondary axle balance rod 222 is provided between the two balance seats 221. The balance seat 221 is used to give the teaching aid a strong balance ability, thereby enhancing its stability during use. The secondary axle balance rod 222 is used to further enhance the integrity of the walking module 2, ensuring that the walking module 2 has strong structural strength. The secondary axle balance rod 222 is fixedly connected to the connecting rod 15. This method can further enhance the integrity between the walking module 2 and the frame 1. At the same time, the steering information of the rear wheel 25 can be fed back to the adjusting rod 12 through the connecting rod 15, thereby causing the frame 1 to rotate accordingly, further ensuring the overall stability of the teaching aid.
[0036] like Figures 4 to 5 As shown, the connecting rod 15 includes a main rod 151 and a connecting platform 152 rotatably connected to the lower end of the main rod 151. The secondary shaft balance rod 222 is set through the connecting platform 152. The two ends of the secondary shaft balance rod 222 are threads with opposite directions of rotation. The secondary shaft balance rod 222 can adjust its length by rotating, thereby making the overall width of the teaching aid adjustable.
[0037] like Figure 4As shown, a steering pin 223 is fixedly connected to the bottom of the balance seat 221. Both ends of the countershaft balance bar 222 are provided with connecting ball sleeves 224 sleeved on the steering pin 223. The clearance fit between the steering pin 223 and the connecting ball sleeves 224 allows the countershaft balance bar 222 to have a certain degree of freedom, which can reduce the sensitivity of the adjusting rod 12 to a certain extent and prevent misoperation.
[0038] like Figure 7 As shown, all the angle adjustment seats 4 mentioned above include two bases 41. When the angle adjustment seat 4 is used to connect the frame 1, the bases 41 are located at both ends of the adjusting rod 12, both ends of the steering rod 14, and the free end of the support rod 13, respectively. When the angle adjustment seat 4 is used to connect the second wheel rod 23 and the first wheel rod 22, the bases 41 are located at the end of the first wheel rod 22 that is close to the second wheel rod 23 and the free end of the turntable 233, respectively. When the angle adjustment seat 4 is used to connect the second wheel rod 23 and the third wheel rod 24, the bases 41 are located at the ends that are close to each other.
[0039] An external ratchet 43 is fixedly connected to the base 41. An internal ratchet 42 meshes between the two external ratchet 43. The internal ratchet 42 and the external ratchet 43 are rotatably connected by a rotating shaft 44. This method allows the two rods connected by the angle adjustment seat 4 to produce a stopping sensation at certain angles when they rotate, thus providing more precise feedback of the rotation angle to the operator. At the same time, the meshing of the ratchet teeth also facilitates precise control of the rotation angle of the rods. The base 41 is provided with a scale 45, and the external ratchet 43 is provided with a pointer 46. The pointer 46 and the scale 45 are used to further make the angle adjustment between the rods more precise and to provide the operator with more accurate feedback. It also makes it easier for the user to position the rods for proper installation during assembly, further improving the convenience of assembly.
[0040] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
