[0001] The invention belongs to the technical field of robots, and in particular relates to a children's educational robot which is convenient for children to operate. Background Art

[0002] At present, children's education is an issue that society and parents attach great importance to. However, due to the fast pace of life and high work pressure, many parents are unable to accompany their children during work hours, nor can they bring their children with them to teach by example. However, since parents' education plays a key role in the growth of children, parents' words and deeds also affect the formation of children's character. Therefore, it is necessary to provide a children's education robot that can accompany children to play and study on behalf of parents when parents are working, and teach children knowledge and life principles according to the wishes of parents. However, the existing children's education robots still have the following shortcomings: it is not convenient to indicate the inclination angle and direction control; the function is single, the educational interactivity is poor, and the fun of children's learning is affected. Therefore, in view of the above situation, it is urgent to develop a robot that is convenient for children's education to overcome the shortcomings in current practical applications.

[0003] The US invention patent, application number US13187709, discloses a robot, including a support frame, a first robot arm, a second robot arm, a connecting member, a first connecting rod, a second connecting rod, a third connecting rod, a driving connecting rod, an action connecting rod and an actuator. The first robot arm is rotatably connected to the support frame, the second robot arm is rotatably connected to the first robot arm, the connecting member is rotatably connected to the second robot arm, the first connecting rod and the second connecting rod, the first connecting rod and the second connecting rod are connected to each other to interconnect the connecting member and the second robot arm, the third connecting rod is rotatably connected to the support frame and the connecting member, the driving connecting rod is rotatably connected to the support frame, the action connecting rod connects the driving connecting rod to the second robot arm, and the actuator is connected to the second connecting rod. The invention has room for improvement in the following aspects: the first and second robot arms and the connecting member are all exposed to the outside, and the axial size of the robot arm is large. When the device is not used for lifting, it occupies a large space, which is not conducive to the safety of people around. Summary of the invention

[0004] The purpose of the present invention is to provide a children's educational robot which can autonomously adjust the height and turning angle of a display screen, is convenient for cleaning the floor and has anti-collision capability and is easy for children to operate.

[0005] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: A children's educational robot that is easy for children to operate, comprising: a base plate, a shell, a display screen and a head, the shell is fixed above the base plate, the head is fixed above the top of the shell, the inner wall of the shell is located above the base plate and is provided with a partition, a lifting component is provided above the partition, the lifting component is connected to a bracket component, the bracket component is connected and fixed to the display screen, and protective components are provided on both sides of the shell. A robot that is easy for children to educate also includes an infrared camera installed at the position of the eyes of the head, a voice input device installed at the position of the ears of the head, a voice output device installed at the position of the mouth of the head, an interface device installed at the back of the head, a main control device installed inside the head, a battery device, a voice recognition device and a wireless network device. The interface device can interact children's learning materials into the robot system, the wireless network device can connect the robot to the smart device to set up the robot, and after the infrared camera detects the child's height, the main control device controls the lifting device to adjust the height of the display screen to facilitate children to watch and use learning materials, and the main control device can control the bracket assembly to fold the display screen to avoid accidental bumps that may cause scratches or cracks on the display screen. The voice recognition device cooperates with the voice input device and the voice output device to interact with the child by voice, enhance interactivity, and improve educational effects. The protective component protects the outer shell and its internal components to avoid damage to the internal components, and on the other hand, it protects children to reduce the chance of children being injured by accidental collisions. The cylindrical outer shell and protective components prevent children from being injured by sharp objects when they collide with the robot.

[0006] Preferably, a placement groove is provided around the bottom surface of the base plate, and an auxiliary wheel is arranged in any of the placement grooves, the auxiliary wheel includes a fixed block and a fixed plate, the fixed block is fixed to the top surface of the placement groove, the fixed plate is fixed to the side wall of the placement groove away from the fixed block, a slide rail is fixed between the fixed block and the fixed plate, a sliding block is slidably provided on the slide rail, an electrically controlled telescopic rod is provided between the sliding block and the fixed plate, a first base is hingedly connected below the fixed block, a first connecting rod is hingedly connected to the side of the first base and the bottom of the sliding block, a bracket is rotatably connected to the first base, and the bracket is rotatably provided with a roller. The rollers are in rolling contact with the ground, and the bracket can rotate axially freely in the first base, so that when the robot moves, each roller can automatically adjust its direction to cooperate with the movement, thereby reducing the wear of the rollers and the ground while achieving movement. The main control device can control the electric telescopic rod to push the sliding block to slide on the slide rail, and the sliding block pulls the first connecting rod to make the first base swing under the fixed block, so that the rollers are stored in the placement groove. The retracting of the rollers can prevent children from being pinched by the rollers on the one hand, which is beneficial to the safety of children. On the other hand, the retracted rollers cooperate with the support members to increase the space under the bottom plate, which is convenient for personnel to clean the bottom surface under the bottom plate. The fixed block, fixed plate, slide rail, sliding block and electric telescopic rod are all arranged in the placement groove, which saves space under the bottom plate, facilitates cleaning, and helps to avoid accidental collision of cleaning tools and damage to components.

[0007] Preferably, protective arc plates are symmetrically arranged on both sides of the bracket, the diameter of the arc-shaped inner wall of the protective arc plate is larger than the diameter of the roller, and the protective arc plate is an elastic plate. The protective arc plate forms an incomplete wrapping of the outer side of the roller, which protects the roller on the one hand to prevent the roller from being stuck by hair or gravel on the ground and unable to roll, and on the other hand to prevent children's feet from directly hitting the roller or toes from being crushed by the roller. The protective arc plate can reduce the impact force of children's feet hitting the roller by deformation, reduce the degree of injury to children's feet after the impact, and is beneficial to the safety of children. When the roller is retracted into the placement groove by the electric control telescopic rod, the protective arc plate protects and blocks the bottom of the roller, reduces the dirt or dirty liquid splashed on the roller when the cleaning tool is cleaned, and causes pollution to the ground when the roller is put down. At the same time, the protective arc plate can prevent the roller from directly contacting the slide rail after being retracted, causing wear, and causing the slide rail to break and fail.

[0008] Preferably, a through groove is opened in the center of the bottom plate, and a support member is provided under the partition, the support member includes a supporting hydraulic column fixed to the bottom surface of the partition, a supporting base is fixed under the supporting hydraulic column, the supporting base includes a cylinder that can slide in the through groove, a first vertebra is fixedly connected under the cylinder, a second vertebra is fixedly connected to the larger end surface at the bottom of the first vertebra, and a rubber ring group is arranged on the side wall of the second vertebra. The wireless network device and the main control device can control the extension of the supporting hydraulic column. The supporting hydraulic column pushes the supporting base to make the cylinder move vertically downward in the through groove, so that the second vertebra at the bottom contacts the ground and lifts the robot, so that the bottom plate of the robot leaves the ground, which is conducive to personnel cleaning and sweeping the ground under the bottom plate. The electric-controlled telescopic rod is used to retract each roller in the retracting groove, thereby increasing the space below the bottom plate on the sides of the first and second vertebrae, which is conducive to the cleaning tools or cleaning robots passing through the ground under the bottom plate, and effectively preventing the cleaning tools or cleaning robots from being stuck under the bottom plate. The storage of the rollers increases the space below after the bottom plate is lifted, which can effectively prevent children's feet from being pinched by the gap between the bottom plate and the ground when approaching the robot. Injury, while reducing the possibility of children's instep hitting the lower edge of the bottom plate, further ensuring the safety of children, the side wall of the second vertebra converges toward the bottom axis to form an inclination, further increasing the cleaning space, which is conducive to cleaning the floor, and the rubber ring located at the edge of the bottom surface of the second vertebra in the rubber ring group contacts the ground, thereby increasing friction, on the one hand, preventing the cleaning tools or cleaning robots from colliding with the second vertebra during cleaning, causing the robot to accidentally slide and injure children or cleaning personnel, on the other hand, the rubber ring group formed by multiple rubber rings protects the side wall of the second vertebra and can absorb the impact force, avoiding the cleaning robot or personnel from colliding with the second vertebra when using cleaning tools, causing damage to the cleaning robot and cleaning tools, and also protecting the second vertebra.

[0009] Preferably, the lifting assembly includes two slides, which are symmetrically arranged on the two vertical inner walls of the shell. Two lifting hydraulic columns are fixedly provided on the upper surface of the bottom plate. The two lifting hydraulic columns pass through the partition and are respectively located in the grooves of the two slides. A slider is fixedly provided on the top of any lifting hydraulic column, and the slider can slide in the slide. The two lifting hydraulic columns can be controlled by the main control device to drive the slider to slide up and down in the slide. The slider drives the height adjustment of the display screen through the bracket assembly, which is convenient for children of different ages and heights to watch the educational videos played on the display screen and operate related games. The groove limits the lateral displacement of the slider, reduces the jitter of the display screen in the horizontal direction, and enhances the interactive experience of children.

[0010] Preferably, the bracket assembly includes two symmetrically arranged first articulated frames and two symmetrically arranged second articulated frames, the two first articulated frames are respectively fixed to the bottom of the two sliders, a first connecting rod and a second connecting rod are hingedly connected between any first articulated frame and the second articulated frame on the same side, and the first connecting rod is arranged parallel to the second connecting rod on the same side, a rectangular groove is opened on any first connecting rod, a hydraulic rod is hingedly connected between the upper end surface of any second connecting rod and the top of the slider on the same side, and any hydraulic rod passes through the rectangular groove on this side, and the two second articulated frames are fixedly connected to the same connecting plate, and the connecting plate is fixedly connected to the bottom of the back of the display screen. The main control device can control the extension and retraction of the hydraulic rod, thereby changing the angle between the first connecting rod and the second connecting rod on both sides relative to the first articulated frames on both sides, so that the connecting plate drives the display screen away from or close to the concave wall of the shell. On the one hand, by adjusting the telescopic displacement of the display screen and coordinating the lifting and lowering of the lifting hydraulic rod, the height position and outward extension distance of the display screen can be further accurately adjusted, which is conducive to children to watch the display screen more clearly and operate the display screen more easily, thereby improving the educational effect. On the other hand, when not in use, the second connecting rod can be folded and kept vertically upward through the cooperation of the lifting hydraulic column and the hydraulic rod, thereby putting the display screen into the concave space of the shell, which is conducive to reducing the probability of the display screen being accidentally scratched or broken by children, and also reduces the possibility of children being injured. When the display screen is in the folded state, educational tools and smart devices for remote control can be placed on the horizontal end surface of the concave space of the shell, thereby increasing the convenience of use. The connecting plate is conducive to maintaining the rotation rate of the second connecting rod and the first connecting rod on both sides, thereby maintaining the stability of the display screen.

[0011] Preferably, the display screen is provided with two arc rods symmetrically arranged above the end surface of the connecting plate, an arc sleeve is fixed to the upper end surface of any second hinged frame, the two arc sleeves are respectively arranged in cooperation with the two arc rods, the outer shell is concave on the side close to the display screen, and the outer shell is symmetrically provided with retractable grooves on the concave wall, and any retractable groove can allow the first connecting rod, the second connecting rod and the second hinged frame on that side to pass through. The arc rod and the arc sleeve are both damping rods. The arc rod can slide in the arc sleeve and cooperate with the hinged connection between the connecting plate and the two second hinge frames to enable the display screen to swing relative to the second hinge frames, thereby adjusting the inclination angle of the display screen, which is beneficial to improving children's experience of watching and operating the display screen and improving the educational effect. The first connecting rod, the second connecting rod, the second hinge frame, the arc rod and the arc sleeve on both sides can pass through the retractable grooves on both sides under the contraction action of the hydraulic rod, so that the display screen can be folded up and its back can fit against the concave vertical end face of the shell. On the one hand, the possibility of objects hitting the display screen and causing the screen to break is reduced. On the other hand, when the robot is knocked down, the display screen located at the concave position of the shell will not contact the ground, reducing the chance of damage to the display screen.

[0012] Preferably, the protective component includes connecting base plates arranged in an array on the vertical walls of the sides of the shell, and buffer bases are arranged at intervals on any of the connecting base plates. Through holes are opened on the upper end face and the lower end face of any of the buffer bases, and rubber columns are slidably arranged in the through holes. An annular protrusion is coaxially fixed to the rubber column, and the annular protrusion is located in the columnar cavity of the buffer base. A spring body sleeved on the rubber column is provided between the bottom surface of the annular protrusion and the bottom surface of the buffer base. An anti-collision plate is arranged on the side of the shell, and the two vertical inner walls of the anti-collision plate are respectively fixedly connected to the adjacent ends of the rubber column. When the robot is hit from the side or falls over, the outer anti-collision plate contacts the impact object and acts on the rubber column. The rubber column absorbs and consumes part of the vibration energy through its own deformation, on the one hand avoiding the rupture and deformation of the anti-collision plate, and on the other hand reducing the vibration transmitted to the shell to avoid damage to the internal components. The compression deformation of the rubber column drives the annular protrusion to move downward in the cylindrical cavity in the buffer matrix and compresses the spring body. The vibration energy is further buffered by the deformation of the spring body, thereby protecting the shell and internal components. When the impact force is too large, the end of the rubber column extending out of the through hole is compressed and flush with the upper end surface of the buffer matrix. At this time, the inner side hard support of the anti-collision plate is provided by the buffer matrix to limit the further displacement of the anti-collision plate, thereby protecting the shell and internal components. The buffer matrix and the rubber column ensure the distance between the shell and the anti-collision plate, which is conducive to air circulation to dissipate heat for the shell and ensure the heat dissipation of the internal components during operation. The anti-collision plate is an elastic shell. When a child accidentally collides with the robot, the anti-collision plate can buffer the impact force through elastic deformation to reduce the chance of injury to the child.

[0013] Preferably, a foam strip is filled between the edge of the inner side wall of the anti-collision plate and the side wall of the shell. The foam strip can provide elastic support for the suspended position at the edge of the anti-collision plate, further improving the buffering capacity of the anti-collision plate against impact when it is hit, which is beneficial to protecting the shell and its internal components. At the same time, the foam strip fills the gap between the edge of the anti-collision plate and the shell, effectively preventing children's hands from being pinched between the anti-collision plate and the shell, which is beneficial to the safety of children. The foam strip can allow airflow to pass while isolating dust and liquid, ensuring the heat dissipation effect of the shell to the outside, while preventing dust or liquid from falling into the gap and being difficult to clean, causing pollution.

[0014] The present invention uses a lifting and swinging display screen in conjunction with the robot's voice interaction to realize children's education, and thus has the following beneficial effects: the auxiliary wheels can be stored to increase the bottom space while the robot moves, which is conducive to cleaning the ground; the lifting of the support member realizes the fixed standing of the robot, prevents the robot from accidentally sliding and thus protects children, and can buffer the accidental impact of the bottom during cleaning; the support member cooperates with the retraction and extension of the pulley to increase the space under the bottom plate, which is conducive to the convenience of cleaning and can prevent the cleaning tool from getting stuck; the protective arc plates on both sides of the roller protect the roller and prevent children's feet from being pinched; the lifting component cooperates with the bracket component to realize the height adjustment and contraction of the display screen, which is convenient for children to make adjustments according to the children, and is convenient for children to watch and operate the display screen, thereby improving the educational effect; the bracket component enables the display screen to be folded into the inner concave part of the shell, reducing the possibility of the display screen being broken and scratched; the protective component buffers and absorbs the side impact of the robot, and its elastic material can also effectively protect children from accidentally hitting the robot. Therefore, the present invention is a children's education robot that can autonomously adjust the height and turning angle of the display screen, and is convenient for cleaning the ground with anti-collision ability, which is easy for children to operate.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0018] See attached Figure 1-3 , a children's educational robot that is easy for children to operate, comprising: a bottom plate 1, a shell 2, a display screen 7 and a head 8, the shell 2 is fixed above the bottom plate 1, the head 8 is fixed above the top of the shell 2, the inner wall of the shell 2 is located above the bottom plate 1 and is provided with a partition 20, a lifting component 5 is provided above the partition 20, the lifting component 5 is connected to a bracket component 6, the bracket component 6 is connected and fixed to the display screen 7, and protective components 9 are provided on both sides of the shell 2. A robot that is easy for children to educate also includes an infrared camera 80 installed at the position of the eyes of the head 8, a voice input device 81 installed at the ear position of the head 8, a voice output device 82 installed at the mouth position of the head 8, an interface device 83 installed on the side of the head 8, a main control device 84 installed inside the head 8, a battery device 85, a voice recognition device 86 and a wireless network device 87, The lifting assembly 5, the bracket assembly 6, the display screen 7, the infrared camera 80, the voice input device 81, the voice output device 82, the interface device 83, the voice recognition device 86, and the wireless network device 87 are all electrically connected to the main control device 84, and the battery device 85 is used to provide power.

[0019] The infrared cameras 80 include at least two, which are respectively installed at the left and right eye positions of the robot head 8, for obtaining the behavior traces of the children, and can cooperate with the display screen 7 to realize video calls between the children and their parents.

[0020] The voice input device 81 is installed at the ear position of the robot head 8, and is used to collect the child's voice and transmit it to the voice recognition device 86 to recognize the voice content.

[0021] The voice output device 82 is installed at the mouth of the robot head 8 and is used to output voice to achieve voice interaction with children.

[0022] The interface device 83 is installed on the side of the robot's head 8. The user can interact with the robot through educational learning materials and interactive games, and display and play them through the display screen 7. Children can be educated by watching the educational videos played on the display screen 7 and operating the interactive games by touching the display screen 7. At the same time, the user can also interact with the scene captured by the robot through the infrared camera 80 to the user's smart device for viewing.

[0023] The voice recognition device 86 is used to receive the voice input by the voice input device 81 and transmit the recognition result to the main control device 84. The main control device 84 analyzes the input voice content and makes control commands to adjust the support member 4, the lifting component 5 and the bracket component 6.

[0024] The wireless network device 87 realizes the connection between the robot and the user's smart device by configuring WIFI and Bluetooth communication. After the child's parents use the smart device to connect to the robot, they can set the robot's voice volume, educational material playback order, etc. through the smart device.

[0025] After the infrared camera 80 detects the height of the child, it transmits the information to the main control device 84. The main control device 84 analyzes the received information and controls the lifting device to adjust the height of the display screen 7 until the display screen 7 reaches a height position that is convenient for the child to watch. When the infrared camera 80 detects that the child has left the robot, the main control device 84 controls the bracket assembly 6 to drive the display screen 7 to move and store, thereby protecting the display screen 7 and preventing accidental bumps from causing scratches or cracks on the display screen 7. The voice recognition device 86 cooperates with the voice input device 81 and the voice output device 82 to interact with the child by voice, enhancing the interactivity of the child watching the display screen 7 and improving the educational effect. The auxiliary wheels 3 at the bottom can realize the movement of the robot and facilitate the replacement of the robot's placement location. The protective component 9 protects the outer shell 2 and its internal components on the one hand to prevent the robot from accidentally falling over and causing damage to the internal components. On the other hand, it protects the child to prevent the child from accidentally colliding and getting injured when playing and running. The curved outer wall of the outer shell 2 and the protective component 9 can reduce the damage caused by the child colliding with the robot.

[0026] See attached Figure 4-7 A placement groove 11 is provided around the bottom surface of the base plate 1, and an auxiliary wheel 3 is arranged in any placement groove 11. The auxiliary wheel 3 includes a fixed block 30 and a fixed plate 31. The fixed block 30 is fixed to the top surface of the placement groove 11, and the fixed plate 31 is fixed to the side wall of the placement groove 11 away from the fixed block 30. A slide rail 32 is fixed between the fixed block 30 and the fixed plate 31, and a slide block 33 is slidably provided on the slide rail 32. An electric-controlled telescopic rod 34 is provided between the slide block 33 and the fixed plate 31. A first base body 35 is hingedly connected to the bottom of the fixed block 30, and a first connecting rod 350 is hingedly connected between the side of the first base body 35 and the bottom of the slide block 33. A bracket 36 is axially rotatably connected to the bottom of the first base body 35. The bracket 36 includes two extended plates, and a shaft body is fixedly connected between the two extended plates. A roller 37 is rotatably provided on the shaft body between the two extended plates of the bracket 36.

[0027] The rollers 37 are in rolling contact with the ground, and the brackets 36 can rotate freely axially in the first base 35, so that when the robot moves, each roller 37 can automatically adjust its direction to cooperate with the movement of the robot, thereby ensuring that there is always rolling friction between the rollers 37 and the ground, and reducing the wear of the rollers 37 and the ground while achieving movement. The main control device 84 can control the electrically controlled telescopic rod 34 to push the sliding block 33 to slide on the sliding rail 32, and the sliding block 33 pulls the first connecting rod 350 to make the first base 35 swing under the fixed block 30, so that the first base 35, the brackets 36 and the rollers 37 are located in the placement groove, so that the rollers 37 are stored. The folding of the rollers 37 can prevent children from being pinched by the rollers 37, which is beneficial to the safety of children. On the other hand, the folded rollers 37 cooperate with the support members 4 to increase the space under the bottom plate 1, which is convenient for personnel to clean the bottom surface under the bottom plate 1.

[0028] Protective arc plates 370 are symmetrically provided on both sides of the bracket 36 . The diameter of the arc-shaped inner wall of the protective arc plate 370 is larger than the diameter of the roller 35 . The protective arc plate 370 is an elastic plate.

[0029] The protective arc plate 370 forms an incomplete wrapping around the outer side of the roller 37. On the one hand, it protects the roller 37 to prevent the roller 37 from being stuck by hair or sand on the ground and unable to roll. On the other hand, it prevents the child's feet from directly hitting the roller 37 or the toes from being crushed by the roller 37. The protective arc plate 370 can reduce the impact force of the child's foot hitting the roller 370 by deformation, reduce the degree of injury to the child's foot after the impact, and is beneficial to the safety of the child. When the roller 37 is retracted into the placement groove 11 by the electric control telescopic rod 34, the protective arc plate 370 protects and blocks the bottom of the roller 37, reduces the splashing of dirt or dirty liquid on the roller 37 when the cleaning tool is cleaning, causing the roller 37 to pollute the ground when it is lowered and rolled, and also prevents the roller 37 from directly contacting the slide rail 32 and causing wear, which causes the slide rail 32 to break.

[0030] A through groove 10 is opened at the center of the bottom plate 1, and a support member 4 is provided under the partition 20. The support member 4 includes a supporting hydraulic column 40 fixed to the bottom surface of the partition 20, and a supporting base 41 is fixed under the supporting hydraulic column 40. The supporting base 41 includes a cylinder 410 that can slide in the through groove 10, and a first vertebral body 411 is fixedly connected to the lower side of the cylinder 410. A second vertebral body 412 is fixedly connected to the larger end surface at the bottom of the first vertebral body 411, and a rubber ring group 42 is arranged on the side wall of the second vertebral body 412.

[0031] The wireless network device 87 and the main control device 84 can control the extension of the supporting hydraulic column 40, and the supporting hydraulic column 40 pushes the supporting base 41 to make the cylinder 410 move vertically downward in the through groove 10, so that the second vertebra 412 at the bottom contacts the ground and lifts the robot, so that the bottom plate 1 of the robot leaves the ground, which is conducive to cleaning the ground under the bottom plate 1. The electric control telescopic rod 34 is used to retract each roller 37 in the placement groove 11, thereby increasing the space below the bottom plate 1 on the sides of the first vertebra 411 and the second vertebra 412, which is conducive to the cleaning tool or the cleaning robot passing through the ground under the bottom plate 1, and effectively preventing the cleaning tool or the cleaning robot from getting stuck. The lifting of the bottom plate 1 and the storage of the roller 37 can effectively prevent children from getting injured in their feet when approaching the robot, ensuring the safety of children. The wall converges toward the bottom axis to form an inclination, which further increases the cleaning space and is beneficial to cleaning the floor. The rubber ring located at the bottom edge of the second vertebra 412 in the rubber ring group 42 contacts the ground, thereby increasing friction. On the one hand, it prevents the cleaning tool or the cleaning robot from colliding with the second vertebra 412 during cleaning, causing the robot to accidentally slide and injure children or cleaning staff. On the other hand, the rubber ring group 42 formed by multiple rubber rings protects the side wall of the second vertebra 412 to prevent the cleaning robot from colliding with the second vertebra 412 and causing damage to both. At the same time, the rubber ring group 42 formed by multiple rubber rings can buffer and absorb the lateral impact force to prevent the cleaning robot or the cleaning tool of the personnel from colliding with the second vertebra 412, causing the bottom of the support base 41 to be unstable and causing the robot to fall over, which is beneficial to the safety of the cleaning staff.

[0032] See attached Figure 7 The lifting assembly 5 includes two slide grooves 50, which are symmetrically arranged on the two vertical inner walls of the outer shell 2. Two lifting hydraulic columns 51 are fixedly provided on the upper end surface of the bottom plate 1. The two lifting hydraulic columns 51 pass through the partition 20 and are respectively located in the grooves of the two slide grooves 50. A slider 52 is fixedly provided on the top of any lifting hydraulic column 51, and the slider 52 can slide in the slide groove 50.

[0033] The two lifting hydraulic columns 51 are controlled by the main control device 84 to drive the slider 52 to slide up and down in the slide groove 50. The slider 52 drives the height adjustment of the display screen 7 through the bracket assembly 6, so as to adapt to children of different ages and heights to watch educational videos played on the display screen 7 and operate related games. The groove limits the lateral displacement of the slider 52, reduces the jitter of the display screen 7 in the horizontal direction, and enhances the interactive experience of children.

[0034] The bracket assembly 6 includes two symmetrically arranged first articulated frames 61 and two symmetrically arranged second articulated frames 62. The two first articulated frames 61 are respectively fixed to the bottom of the two sliders 52. A first connecting rod 63 and a second connecting rod 64 are hingedly connected between any first articulated frame 61 and the second articulated frame 62 on the same side, and the first connecting rod 63 is arranged in parallel with the second connecting rod 64 on the same side. A rectangular groove 640 is opened on any first connecting rod 63. A hydraulic rod 65 is hingedly connected between the upper end surface of any second connecting rod 64 and the top of the slider 52 on the same side. Any hydraulic rod 65 passes through the rectangular groove 640 on this side. The two second articulated frames 62 are fixedly connected to the same connecting plate 66, and the connecting plate 66 is fixedly connected to the bottom of the back of the display screen 7.

[0035] The main control device 84 can control the extension and retraction of the hydraulic rod 65, thereby changing the angle between the first connecting rod and the second connecting rod on both sides relative to the first articulated frames 61 on both sides, so that the connecting plate 66 drives the display screen 7 away from or close to the concave wall of the shell 2. On the one hand, by adjusting the telescopic displacement of the display screen 7 and coordinating the lifting and lowering of the lifting hydraulic rod 65, the height position and the outward extension distance of the display screen 7 can be further accurately adjusted, which is conducive to children to watch the display screen 7 more clearly and to operate the display screen 7 more easily, thereby improving the educational effect. On the other hand, when not in use, the second connecting rod 64 can be folded and kept vertically upward through the cooperation of the lifting hydraulic column 51 and the hydraulic rod 65, thereby putting the display screen 7 into the concave space of the shell 2, which is conducive to reducing the probability of the display screen 7 being accidentally scratched and broken by children, and also reduces the possibility of children being injured. In addition, when the display screen 7 is in the folded state, educational tools and intelligent devices for remote control can be placed on the horizontal end surface of the concave space of the shell 2, thereby increasing the convenience of use. The connecting plate 66 is conducive to maintaining the rotation rate of the second connecting rod 64 and the first connecting rod 63 on both sides, thereby maintaining the stability of the display screen 7.

[0036] The display screen 7 is provided with two arc rods 71 ​​symmetrically arranged above the end surface of the connecting plate 66, and an arc sleeve 72 is fixed to the upper end surface of any second hinged frame 62. The two arc sleeves 72 are respectively arranged in cooperation with the two arc rods 71. The outer shell 2 is concave on the side close to the display screen 7, and the outer shell 2 is symmetrically provided with retractable grooves 2110 on the concave wall. Any retractable groove 2110 can allow the first connecting rod 63, the second connecting rod 64 and the second hinged frame 62 on that side to pass through.

[0037] The arc rod 71 and the arc sleeve 72 are both damping rods. The arc rod 71 slides in the arc sleeve 72 and cooperates with the connecting plate 66 to be hingedly connected with the two second hinge frames 62, so that the display screen 7 can swing relative to the second hinge frames 62, thereby adjusting the inclination angle of the display screen 7, which is beneficial to improving children's viewing and operating experience of the display screen 7 and improving the educational effect. The first connecting rod 63, the second connecting rod 64, the second hinge frame 62, the arc rod 71 and the arc sleeve 72 on both sides can pass through the retractable grooves 2110 on both sides under the contraction action of the hydraulic rod 65, so that the display screen 7 can be folded and fit to the concave vertical end face of the outer shell 2. On the one hand, the possibility of objects hitting the display screen 7 and causing it to break is reduced. On the other hand, when the robot is knocked down, the display screen 7 located at the concave position of the outer shell 2 will not contact the ground, reducing the probability of damage to the display screen 7.

[0038] See attached Figure 8-10 The protection component 9 includes a connecting base plate 90 arranged in an array on the vertical wall of the side of the shell 2, and a buffer base 91 is arranged at intervals on any connecting base plate 90. The upper end surface and the lower end surface of any buffer base 91 are provided with a through hole, and a rubber column 92 is slidably provided in the through hole. The rubber column 92 is coaxially fixed with an annular protrusion 93, and the annular protrusion 93 is located in the columnar cavity of the buffer base 91. A spring body 94 sleeved on the rubber column 92 is provided between the bottom surface of the annular protrusion 93 and the inner bottom surface of the buffer base 91. An anti-collision plate 95 is arranged on the side of the shell 2, and the two vertical inner walls of the anti-collision plate 95 are respectively fixedly connected to the adjacent ends of the rubber column 92.

[0039] When the robot is hit from the side or falls over, the outer anti-collision plate 95 contacts the impact object and acts on the rubber column 92. The rubber column 92 absorbs and consumes part of the vibration energy through its own deformation, thereby avoiding the rupture and deformation of the anti-collision plate 95 and reducing the vibration transmitted to the outer shell 2 to avoid damage to the internal components. The compression deformation of the rubber column 92 drives the annular protrusion 93 to move downward in the cylindrical cavity in the buffer base 91 and compresses the spring body 94. The deformation of the spring body 94 further buffers the vibration energy, thereby protecting the outer shell 2 and the internal components. When the impact force is too large, the rubber column 92 stretches The end of the through hole is compressed and flush with the upper end surface of the buffer base 91. At this time, the buffer base 91 provides hard support on the inner side of the anti-collision plate 95 to limit the further displacement of the anti-collision plate 95, thereby protecting the outer shell 2 and the internal components. The buffer base 91 and the rubber column 92 ensure the distance between the outer shell 2 and the anti-collision plate 95, which is conducive to air circulation to dissipate heat for the outer shell 2 and ensure that the heat of the internal components can be dissipated during operation. The anti-collision plate 95 is an elastic shell. When a child accidentally collides with the robot, the anti-collision plate 95 can buffer the impact force through elastic deformation to reduce the chance of child injury.

[0040] A foam strip 950 is filled between the edge of the inner wall of the anti-collision plate 95 and the side wall of the shell 2 .

[0041] The foam strip 950 can provide elastic support for the suspended position at the edge of the anti-collision plate 95, further improving the impact buffering ability of the anti-collision plate 95 when it is hit, which is beneficial to protecting the shell 2 and its internal components. At the same time, the foam strip 950 fills the gap between the edge of the anti-collision plate 95 and the shell 2, effectively preventing children's hands from being pinched between the anti-collision plate 95 and the shell 2, which is beneficial to the safety of children. The foam strip 950 allows air flow to pass through while isolating dust and liquid. While ensuring the outward heat dissipation effect of the shell 2, it prevents dust or liquid from falling into the gap and being retained, which is difficult to clean and causes pollution. Example

[0042] See attached Figure 1-6 When the robot is placed in the home or other indoor scenes for use, the user sends a command to the main control device 84 through the user's smart device. The main control device 84 controls the retractable end of the supporting hydraulic column 40 to extend downward, thereby pushing the cylinder 410 to slide downward in the through groove 10, so that the bottom surface of the second vertebral body 412 contacts the ground. After contact, the cylinder 410 continues to move downward, so that the bottom plate 1 leaves the ground. At this time, the robot provides support for the bottom center of the robot through the supporting base 41; the personnel can use cleaning tools or control the cleaning robot to clean the ground outside the supporting base 41, and can also clean each roller 37 at the same time.

[0043] When the support base 41 lifts the robot to a certain height off the ground, the user sends a command to the main control device 84 through the smart device. After receiving the signal, the main control device 84 controls each electrically controlled telescopic rod 34 to pull the sliding block 33 at the same rate, so that each sliding block 33 moves inward on the slide rail 32. The sliding block 33 drives the bracket 36 to swing at the bottom of the first base 35 through the first connecting rod 350, so that the first base 35, the bracket 36 and the roller 37 are stored in the placement groove 11, which effectively increases the space below the bottom plate 1 outside the support base 41, making it easier for the cleaning robot and cleaning tools to clean the ground, and preventing the cleaning tools from getting stuck in the space and being unable to be removed.

[0044] After cleaning is completed, the user sends a command to the main control device 84 through the smart device. The main control device 84 controls the electric telescopic rod 34 to extend and push each sliding block 33. The sliding block 33 swings the first base 35 under the fixed block 30 through the first connecting rod 350, thereby driving the bracket 36 and the roller 37 to be released from the placement groove 11. At this time, the main control device 84 controls the supporting hydraulic column 40 to move the supporting base 41 upward until the roller 37 in the auxiliary wheel 3 contacts the ground, thereby realizing the robot's mobility on the ground.
