Description

Technical Field

[0001] This invention belongs to the field of educational robot accessories technology, and in particular relates to a balancing structure for an artificial intelligence educational robot. Background Technology

[0002] With the development of artificial intelligence, computer technology, and other related technologies, research on intelligent robots is increasing. In the field of education, especially in children's education, a series of robots with educational functions have emerged. Educational robots are not only used for children's early education but also serve as playmates. However, existing educational robots have the following shortcomings in practical use:

[0003] 1. Because educational robots contain certain precision components, and children are at an age where they are very active, they often play with the robots out of curiosity, which can easily damage them. At the same time, there are also certain safety hazards for children themselves (such as accidentally swallowing parts).

[0004] 2. Because educational robots contain certain interactive components (such as displays), and many educational robots are set to move automatically, they are very prone to bumps and overturning during the robot's movement, which can lead to damage to the interactive components.

[0005] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a balancing structure for an artificial intelligence educational robot that is safe and stable in walking, thus solving the problems of low safety and poor walking stability in existing educational robots.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] This invention relates to a balancing structure for an artificial intelligence educational robot, comprising a base plate and a connecting plate arranged coaxially from bottom to top. An adjusting rod is also arranged along the radial direction above the base plate, and an adjusting groove is formed on the top surface of the adjusting rod. A screw rod is arranged along the long side of the adjusting groove, and both ends of the screw rod are rotatably connected to the adjusting rod via rolling bearings. A movable block is screwed onto the screw rod, and the movable block is loosely fitted within the adjusting groove. A first rotating shaft is fixedly connected to one side of the bottom surface of the adjusting rod, and the lower end of the first rotating shaft is embedded in the output end of a first motor. A through hole for the first rotating shaft to slide through is formed at the center of the base plate, and a rectangular groove for placing the first motor is formed on the bottom surface of the base plate. A second rotating shaft is fixedly mounted on the top surface of the movable block, and the upper end of the second rotating shaft slides through the bottom plate of the connecting plate and is embedded in the output end of the second motor. The second motor is fixedly connected to the inner bottom surface of the connecting plate.

[0009] Furthermore, one end of the screw rod extends to the outside of the adjusting rod and fits into the output end of the third motor, and the third motor is fixedly connected to the end face of the adjusting rod.

[0010] Furthermore, guide bars are symmetrically arranged in the adjustment grooves on both sides of the screw rod, and guide grooves for clearance fit of the guide bars are provided on the movable block.

[0011] Furthermore, a rotating column is fixed on the bottom surface of the other end of the adjusting rod with the first rotating shaft. The lower end of the rotating column is rotatably connected to a roller through a rolling bearing. A guide groove for clearance fit of the roller is opened along the circumferential direction on the top surface of the base plate.

[0012] Furthermore, a support sleeve is fixed on the top surface of the movable block on the outer side of the second rotating shaft, a limiting ring is fixed on the top surface of the support sleeve, and a limiting groove for clearance fit of the limiting ring is opened on the bottom surface of the connecting plate.

[0013] Furthermore, multiple reinforcing ribs are fixedly arranged in a circumferential array on the lower outer wall of the support sleeve, and the reinforcing ribs are fixedly connected to the top surface of the movable block.

[0014] Furthermore, multiple mounting holes are arranged in a circumferential array along the outer edge of the top surface of the connecting plate.

[0015] Furthermore, the base plate consists of two symmetrical semicircular plates. A rectangular frame is fixedly fitted onto the first motor. Support plates are provided on both sides of the rectangular frame. A first connecting post and a second connecting post are slidably fitted onto the upper and lower ends of the support plates, respectively. Both ends of the first connecting post are fixedly connected to the rectangular frame through a first connecting piece, and both ends of the second connecting post are fixedly connected to the semicircular plate through a second connecting piece. An electric push rod is fixedly provided on the bottom surface of one of the semicircular plates, and a fixing piece is fixedly provided on the telescopic end of the electric push rod. The fixing piece is fixedly connected to the bottom surface of the other semicircular plate.

[0016] Furthermore, a return spring is slidably sleeved on the first and second connecting posts on both sides of the support plate, and the two ends of the return spring are fixedly connected to the support plate and the first or second connecting piece, respectively.

[0017] Furthermore, one of the semicircular plates is fixedly equipped with insert plates on both sides of the rectangular groove, and the other semicircular plate is provided with a slot for the insert plates to fit together; a drive wheel assembly is also fixedly installed on the bottom surface of the semicircular plate.

[0018] The present invention has the following beneficial effects:

[0019] 1. In use, the robot's interaction and main control device is mounted on the connecting plate. Through the operation of the first motor, the adjusting rod can rotate around the first rotating axis. Through the operation of the third motor, the movable block can move along the axis of the screw rod. With the cooperation of the above settings, the robot's main body can move horizontally. In addition, with the infrared sensing device on the robot's main body, the robot's main body can automatically avoid touching the device before a child's hand touches it, thus protecting the robot and reducing the safety hazards to the child.

[0020] 2. When in use, the two semicircular plates can move in opposite directions by extending the electric push rod. Because the two ends of the support plate are slidably sleeved with the first connecting column and the second connecting column respectively, the entire first motor will move downward when the two semicircular plates move in opposite directions. This lowers the center of gravity of the entire robot during movement, ensuring stability during transport and improving the service life of the device. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] Please see Figures 1 to 7 As shown, this invention relates to a balancing structure for an artificial intelligence educational robot, comprising a base plate 1 and a connecting plate 2 arranged coaxially from bottom to top. Multiple mounting holes 201 are arranged circumferentially along the outer edge of the top surface of the connecting plate 2. The mounting holes 201 are used for the fixed connection of the robot's interaction mechanism and main control mechanism (hereinafter referred to as the robot body). An adjusting rod 3 is also arranged radially above the base plate 1, and an adjusting groove is formed on the top surface of the adjusting rod 3. A screw rod 301 is arranged along the long side of the adjusting groove, and both ends of the screw rod 301 are rotatably connected to a rolling bearing. On the adjusting rod 3, one end of the screw rod 301 extends to the outside of the adjusting rod 3 and is fitted into the output end of the third motor 3011. The third motor 3011 is fixedly connected to the end face of the adjusting rod 3. A movable block 5 is screwed on the screw rod 301 and is fitted with the adjusting groove with a clearance. Guide bars 304 are symmetrically arranged in the adjusting grooves on both sides of the screw rod 301. A guide groove 503 is provided on the movable block 5 for the clearance fit of the guide bar 304. This arrangement can limit and guide the movement of the movable block 5 when it moves along the axial direction of the screw rod 301.

[0035] The bottom side of the adjusting rod 3 is fixedly connected to the first rotating shaft 3031, and the lower end of the first rotating shaft 3031 is fitted into the output end of the first motor 303. The center of the base plate 1 is provided with a through hole 105 for the first rotating shaft 3031 to slide through, and the bottom surface of the base plate 1 is provided with a rectangular groove 104 for the first motor 303 to be placed.

[0036] A rotating column 3021 is fixed on the bottom surface of the other end of the adjusting rod 3, which is provided with the first rotating shaft 3031. The lower end of the rotating column 3021 is rotatably connected to the roller 302 through a rolling bearing. A guide groove 101 for clearance fit of the roller 302 is provided on the top surface of the base plate 1. This arrangement can limit and guide the movement of the adjusting rod 3 when it moves along the circumference of the base plate 1, and the roller 302 can also provide auxiliary support for the adjusting rod 3.

[0037] In use, the above-mentioned configuration allows the first rotating shaft 3031 to rotate, driven by the first motor 3031, thereby enabling the robot body to move circumferentially along the base plate 1. The third motor 3011 enables the screw rod 301 to rotate. Due to the helical engagement between the screw rod 301 and the movable block 5, the movable block 5 can move along the axis of the screw rod 301, thereby enabling the robot body to move horizontally. Through the coordination of the above movements, the robot body can avoid children during use, preventing them from touching it.

[0038] Additionally, it should be noted that in order to effectively avoid children's touch, an infrared ranging sensor can be installed on the robot body to accurately detect the child's position and achieve effective avoidance. At the same time, all electrical components in this device are centrally controlled through the robot body.

[0039] Please see Figures 3 to 5 As shown, a second rotating shaft 5011 is fixedly mounted on the top surface of the movable block 5. The upper end of the second rotating shaft 5011 slides through the bottom plate of the connecting disk 2 and is embedded in the output end of the second motor 501. The second motor 501 is fixedly connected to the inner bottom surface of the connecting disk 2. A support sleeve 502 is fixedly mounted on the top surface of the movable block 5 outside the second rotating shaft 5011. The support sleeve 502 can improve the stability of the second rotating shaft 5011. A limiting ring 5021 is fixedly mounted on the top surface of the support sleeve 502. A limiting groove 202 for clearance fit of the limiting ring 5021 is opened on the bottom surface of the connecting disk 2. This setting can limit and guide the movement of the connecting disk 2. Multiple reinforcing ribs 5022 are fixedly mounted in a circumferential array on the lower outer wall of the support sleeve 502. The reinforcing ribs 5022 are fixedly connected to the top surface of the movable block 5, thereby improving the stability of the support sleeve 502.

[0040] When in use, the above-mentioned setting enables the connecting plate 2 to rotate around the second rotating shaft 5011 through the operation of the second motor 501. This setting ensures that the interactive mechanism is always facing the child when the robot body avoids obstacles, thus achieving both obstacle avoidance and normal robot use.

[0041] Please see Figures 1 to 3 , Figure 8 and Figure 9 As shown, the base plate 1 consists of two symmetrical semicircular plates 106. A rectangular frame 4 is fixedly sleeved on the first motor 303. Support plates 401 are provided on both sides of the rectangular frame 4. The upper and lower ends of the support plates 401 are respectively slidably sleeved with a first connecting post 402 and a second connecting post 1041. This arrangement allows for free position adjustment of both ends of the support plates 401. Both ends of the first connecting post 402 are fixedly connected to the rectangular frame 4 through a first connecting piece 4021. Both ends of the second connecting post 1041 are fixedly connected to the semicircular plate 106 through a second connecting piece 1042. An electric push rod 103 is fixedly mounted on the bottom surface of one of the semicircular plates 106, and a fixing piece 1031 is fixedly mounted on the telescopic end of the electric push rod 103. The fixing piece 1031 is fixedly connected to the bottom surface of the other semicircular plate 106.

[0042] A return spring 403 is slidably sleeved on the first connecting post 402 and the second connecting post 1041 on both sides of the support plate 401. The two ends of the return spring 403 are fixedly connected to the support plate 401 and the first connecting piece 4021 or the second connecting piece 1042, respectively. This arrangement can provide a force for movement when the support plate 401 is reset, making it easier to reset.

[0043] One of the semicircular plates 106 is fixed with insert plates 1061 on both sides of the rectangular groove 104, and the other semicircular plate 106 is provided with a slot 1062 for clearance fit of the insert plates 1061. This arrangement can realize the limiting guidance when the two semicircular plates 106 move relative to each other. A drive wheel set 102 is also fixedly installed on the bottom surface of the semicircular plate 106. The drive wheel set 102 can realize the movement of this device according to the instructions of the robot body.

[0044] In use, the above-mentioned configuration allows the two semicircular plates 106 to move in opposite directions or towards each other by extending and retracting the electric push rod 103. When the two semicircular plates 106 move in opposite directions, the lower end of the support plate 401 moves outward, thereby causing the rectangular frame 4 to drive the first motor 303 to move downward, lowering the overall center of gravity. When the two semicircular plates 106 move towards each other, the lower end of the support plate 401 moves inward, thereby causing the rectangular frame 4 to drive the first motor 303 to move upward, thus enabling the robot body to move upward.

[0045] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
