Description

Technical Field

[0001] This invention relates to the field of artificial intelligence technology, and more specifically to an artificial intelligence device with obstacle removal function. Background Technology

[0002] Artificial intelligence (AI) robots refer to robots designed, assembled, programmed, and operated to achieve control and perform various functions according to instructions. This technology integrates mechanical principles, electronic sensors, computer hardware and software, and artificial intelligence, among other advanced technologies. AI robots can be applied in various fields, such as medicine, education, entertainment, and the military. In the medical field, AI robots can assist doctors in diagnosis and treatment, improving medical standards and efficiency. In education, AI robots can provide personalized teaching, helping students improve their learning outcomes. In entertainment, AI robots can provide services such as intelligent voice interaction and intelligent recommendations. In the military field, AI robots can be used for reconnaissance, patrol, and attack missions.

[0003] With the popularization and education of artificial intelligence, AI educational robots have entered our lives. However, when encountering obstacles, AI robots are not good at judging and clearing obstacles, requiring manual removal of obstacles or the robot to detour. In severe cases, the robot may collide with the obstacle, which greatly affects its operating efficiency and speed. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide an adjustable intelligent disinfection cabinet for medical devices. A storage slot is provided on the top surface of the turntable of the push-pull mechanism, and a rotating seat is fixedly connected to the side wall of the storage slot. A pneumatic multi-section telescopic rod is rotatably connected inside the rotating seat. A limiting rod is fixedly connected to the outer wall of the pneumatic multi-section telescopic rod, and a second limiting rod is fixedly connected to the top of the pneumatic multi-section telescopic rod. This allows the limiting rods to trap obstacles between them, which are then moved to other positions as the device moves. A transmission belt is provided in the conveying mechanism, and the transmission belt internally supports a belt drive pulley, a belt drive pulley, two belt limiting pulleys, and several rotating wheels. A rotating shaft is rotatably connected inside each rotating wheel, and the top surface of the rotating shaft is fixedly connected to the bottom surface of a partition. A moving mechanism is fixedly connected to the bottom surface of the rotating shaft. The motor shaft of a motor is rotatably connected inside the belt drive pulley. A connecting plate is rotatably connected to the outer wall of the belt drive pulley, and the motor shaft of a motor is rotatably connected inside the belt drive pulley. A flexible multi-section telescopic rod is fixedly connected to the side wall of the device. An air pump box is fixedly connected to the other end of the flexible multi-section telescopic rod. Pneumatic multi-section telescopic rods (secondary) are fixedly connected to both the left and right sides of the air pump box. A connecting plate (secondary) is fixedly connected to the other end of the pneumatic multi-section telescopic rod. The interior of the connecting plate (secondary) is rotatably connected to a belt-driven limit wheel. The belt-driven pulleys (first and second) rotate in opposite directions, increasing the conveying power and causing obstacles to move along the belt's trajectory when they touch it. A return spring is fixed inside the flexible multi-section telescopic rod, keeping it in an extended state. When the air pump (firstary) inflates the pneumatic multi-section telescopic rod (secondary) to extend it outwards, the belt-driven limit wheel tightens the belt. The tightened belt squeezes the belt-driven pulley (secondary), causing the flexible multi-section telescopic rod to contract. When the air pump (firstary) draws air into the pneumatic multi-section telescopic rod (secondary), it contracts. The unpressurized return spring then causes the flexible multi-section telescopic rod to continue extending, returning to its initial position.

[0009] Furthermore, the moving mechanism includes a moving base, the top surface of which is fixedly connected to the bottom surface of the rotating shaft, a sliding groove on the top surface of the moving base, a sliding connection between the inside of the sliding groove and motor two, a motor slot on the top surface of the moving base, a fixed connection between the inside of the motor slot and the bottom surface of motor one, two drive wheels rotatably connected to the bottom surface of the moving base, and universal wheels rotatably connected to the bottom surface of the moving base.

[0010] Furthermore, an air pump is fixedly connected inside the air pump box. The air pump includes two air pipes, which are respectively fixedly connected to two pneumatic multi-section telescopic rods.

[0012] Furthermore, the outer walls of the first and second limiting rods are covered with rubber sleeves.

[0013] Furthermore, a return spring is fixed inside the elastic multi-section telescopic rod, which keeps the elastic multi-section telescopic rod in an extended state.

[0014] Furthermore, a 3D camera and a sensor are fixedly connected to the outer arc surface of the turntable.

[0015] The beneficial effects of this invention are:

[0016] 1. A storage slot is provided on the top surface of the turntable of the push-pull mechanism, and a rotating seat is fixedly connected to the side wall of the storage slot. A pneumatic multi-section telescopic rod is rotatably connected inside the rotating seat. A limit rod is fixedly connected to the outer wall of the pneumatic multi-section telescopic rod. A limit rod is fixedly connected to the top of the pneumatic multi-section telescopic rod. A toothed ring is fixedly connected to the bottom surface of the turntable, and a support mechanism is rotatably connected to the bottom surface of the turntable. This allows the limit rod and the limit rod to hold the obstacle between them and move it to another position as the device moves.

[0017] 2. By incorporating a transmission belt into the conveying mechanism, the internal support of the transmission belt includes a belt drive pulley 1, a belt drive pulley 2, two belt limit pulleys, and several rotating pulleys.

[0018] 3. A return spring is fixed inside the elastic multi-section telescopic rod, and the return spring keeps the elastic multi-section telescopic rod in an extended state. When the air pump blows air into the second pneumatic multi-section telescopic rod, causing it to extend outward, the belt limit pulley will tighten the transmission belt. The tightened transmission belt will squeeze the second belt drive pulley, causing the elastic multi-section telescopic rod to contract. When the air pump draws air into the second pneumatic multi-section telescopic rod, the second pneumatic multi-section telescopic rod will contract. At this time, the return spring, which loses pressure, will cause the elastic multi-section telescopic rod to continue to extend and return to its initial position. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-9As shown, an artificial intelligence device with obstacle removal function includes a push-pull mechanism 100, which includes a turntable 110. The top surface of the turntable 110 has a storage groove 120. A rotating seat 121 is fixedly connected to the side wall of the storage groove 120. A pneumatic multi-section telescopic rod 130 is rotatably connected inside the rotating seat 121. A limit rod 131 is fixedly connected to the outer wall of the pneumatic multi-section telescopic rod 130. A limit rod 2 132 is fixedly connected to the top of the pneumatic multi-section telescopic rod 130. A toothed ring 140 is fixedly connected to the bottom surface of the turntable 110. A support mechanism 400 is rotatably connected to the bottom surface of the turntable 110. The limit rod 131 and the limit rod 2 132 can trap obstacles between them, which are then moved to other positions as the device moves.

[0031] The support mechanism 400 includes a partition 410, a column fixedly connected to the top surface of the partition 410, the top of the column being rotatably connected to the inner top surface of the turntable 110, a support leg 440 fixedly connected to the top surface of the partition 410, a motor 420 fixedly connected inside the support leg 440, a spur gear 430 being driven by the motor shaft of the motor 420, the spur gear 430 meshing with the gear ring 140, and a conveying mechanism 300 fixedly connected to the bottom surface of the partition 410, the spur gear 430 meshing with the turntable 110, so that the unfolded pneumatic multi-section telescopic rod 130 can smoothly push away obstacles.

[0032] The conveying mechanism 300 includes a transmission belt 320. The transmission belt 320 internally supports a belt drive pulley 330, a belt drive pulley 340, two belt limit pulleys 360, and several rotating pulleys 310. A rotating shaft 311 is rotatably connected inside each rotating pulley 310. The top surface of the rotating shaft 311 is fixedly connected to the bottom surface of a partition plate 410. A moving mechanism 200 is fixedly connected to the bottom surface of the rotating shaft 311. The motor shaft of a motor 331 is internally connected to the belt drive pulley 330. A connecting plate 342 is rotatably connected to the outer wall of the belt drive pulley 340. The internal transmission of the 0 is connected to the motor shaft of the second motor 341. The side wall of the first connecting plate 342 is fixedly connected to the elastic multi-section telescopic rod 343. The other end of the elastic multi-section telescopic rod 343 is fixedly connected to the air pump box 350. The left and right side walls of the air pump box 350 are both fixedly connected to the second pneumatic multi-section telescopic rod 362. The other end of the second pneumatic multi-section telescopic rod 362 is fixedly connected to the second connecting plate 361. The interior of the second connecting plate 361 is rotatably connected to the belt limit wheel 360. The rotation directions of the first belt drive wheel 330 and the second belt drive wheel 340 are always opposite, which increases the power of conveying.

[0033] The moving mechanism 200 includes a moving base 210, the top surface of which is fixedly connected to the bottom surface of a rotating shaft 311. A sliding groove 211 is provided on the top surface of the moving base 210, and the interior of the sliding groove 211 is slidably connected to a second motor 341. A motor slot 212 is provided on the top surface of the moving base 210, and the interior of the motor slot 212 is fixedly connected to the bottom surface of a first motor 331. Two drive wheels 220 are rotatably connected to the bottom surface of the moving base 210, and a universal wheel 221 is rotatably connected to the bottom surface of the moving base 210. The two drive wheels 220 provide power for the movement of the equipment and also provide support. The universal wheel 221 is used to steer the equipment. An air pump is fixedly connected inside the air pump box 350. The air pump includes two air pipes, which are respectively fixedly connected to the interior of two pneumatic multi-section telescopic rods 362, and are used to drive the pneumatic multi-section telescopic rods 362 to extend or retract.

[0034] A motor is fixedly connected inside the rotating base 121 to drive the pneumatic multi-section telescopic rod 130 to rotate, unfold, or retract. An air pump is fixedly connected inside the turntable 110. The air pipe of the air pump is fixedly connected to the inside of the pneumatic multi-section telescopic rod 130 to drive the pneumatic multi-section telescopic rod 130 to extend or retract as needed. The outer walls of the limiting rods 131 and 132 are covered with rubber sleeves to prevent the limiting rods 131 and 132 from wearing on the side walls of the storage slot 120 when the pneumatic multi-section telescopic rod 130 is retracted into the storage slot 120, thus increasing the service life of the equipment.

[0035] The elastic multi-section telescopic rod 343 has a fixed return spring inside, which keeps the elastic multi-section telescopic rod 343 in an extended state. When the air pump blows air into the pneumatic multi-section telescopic rod 362, causing it to extend outward, the belt limit wheel 360 will tighten the transmission belt 320. The tightened transmission belt 320 will squeeze the belt drive wheel 340, causing the elastic multi-section telescopic rod 343 to contract. When the air pump draws air into the pneumatic multi-section telescopic rod 362, the pneumatic multi-section telescopic rod 362 will contract. At this time, the return spring, which loses pressure, will cause the elastic multi-section telescopic rod 343 to continue to extend and return to the initial position. The outer arc surface of the turntable 110 is fixedly connected to a 3D camera and sensor for observing the position of obstacles and accurately removing obstacles.

[0036] Working principle: When in use, the artificial intelligence device is activated, activating the 3D camera and sensors. The drive wheel 220 moves the device on the ground, while the casters 221 adjust the direction of travel. Drive motors 331 and 341 transmit power to belt pulleys 330 and 340, causing the drive belt 320 to move. When the device encounters a light obstacle, it moves closer to the obstacle, causing the drive belt 320 to press against the obstacle's surface, thus moving the obstacle along the path conveyed by the drive belt 320. The drive air pump 1 then pumps air through the air pipe into the two pneumatic multi-section telescopic rods 362. Inflating the air pump causes the two pneumatic multi-section telescopic rods 362 to extend. The two pneumatic multi-section telescopic rods 362 push the transmission belt 320 outward to prevent obstacles from moving out of line. When the pneumatic multi-section telescopic rods 362 extend, the transmission belt 320 will tighten and put pressure on the belt drive pulley 340, causing the return spring inside the elastic multi-section telescopic rod 343 to contract. When the air pump stops blowing air into the pneumatic multi-section telescopic rods 362 and starts sucking air in, the pneumatic multi-section telescopic rods 362 drive the transmission belt 320 to contract. At this time, the return spring pushes the elastic multi-section telescopic rod 343 to extend, causing the belt drive pulley 340 to return to its original position.

[0037] When the drive belt 320 alone is insufficient to move the obstacle, the drive motor 4 extends the pneumatic multi-section telescopic rod 130 stored in the storage slot 120. The extension of the pneumatic multi-section telescopic rod 130 is selected according to the size of the obstacle. The start motor 3 420 causes the spur gear 430 and the gear ring 140 to mesh and drive, causing the entire push-pull mechanism 100 to rotate. The obstacle is stuck between the limit rod 131 and the drive belt 320 or between the limit rod 131 and the limit rod 2 132. The spur gear 430 continues to mesh and drive with the gear ring 140, causing the limit rod 131 and the limit rod 2 132 to carry the obstacle away from the current position.
