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.

[0032] See also Figure 1-Figure 9 A visual tour guide robot comprises a tour guide robot body 1; a moving mechanism 2; an adjusting mechanism 3; an anti-collision mechanism 4; and a driving box 5; the lower surface of the tour guide robot body 1 is fixedly connected to the driving box 5, the inner surface of the driving box 5 is fixedly connected to the moving mechanism 2, the driving box 5 is provided with the adjusting mechanism 3, and the driving box 5 is provided with the anti-collision mechanism 4;

[0033] The moving mechanism 2 includes a bidirectional motor 21, and a rotating rod 22 is rotatably connected to the output shaft of the bidirectional motor 21. One end of the rotating rod 22 is ring-shaped, and the other end of the rotating rod 22 is hook-shaped. By setting the other end of the rotating rod 22 to be hook-shaped, it can be effectively ensured that when the corner of the display cabinet is higher than the rotating rod 22, the rotating rod 22 will be stuck in the lower part of the corner of the display cabinet, and will not cause damage to the guide robot. When the corner of the display cabinet is lower than the hook-shaped end of the rotating rod 22, the arc surface of the rotating rod 22 will be squeezed by the corner of the display cabinet and tilted upward. The hook-shaped end of the rotating rod 22 is rotatably connected to a moving wheel 23, and the moving wheel 23 is connected to the output shaft of the bidirectional motor 21 through a transmission belt. The rotating rod 22 is provided with two groups, and the two groups of rotating rods 22 are rotatably connected through a connecting rod 6. The connecting rod 6 is connected to the moving wheel 23 through a transmission belt. The moving wheel 23 is provided with two groups, and the two groups of moving wheels 23 are connected through a transmission rod. The outer arc surface of the connecting rod 6 is a circular array The cleaning brush 7 is fixedly connected to the connecting rod 6 through the output shaft and the transmission belt of the bidirectional motor 21. The cleaning brush 7 arranged on the connecting rod 6 can rotate to clean the ground. The front surface of the rotating rod 22 is rotatably connected to the U-shaped rod 62, and the rear surface of the U-shaped rod 62 is rotatably connected to the dustbin 63. The right surface of the dustbin 63 is fixedly connected to a counterweight bar 64. In order to ensure that the dustbin 63 can be movable, the U-shaped rod 62 and the dustbin 63 are fixed, and the right surface of the dustbin 63 is made heavier by the counterweight bar 64. The length of the dustbin 63 is the same as that of the cleaning brush 7. In order to facilitate the cleaning brush 7 to enter the dustbin 63 when rotating clockwise, the opening of the dustbin 63 is set to the left. At the same time, a counterweight bar 64 is fixed on the dustbin 63, so that after the guide robot body 1 is lifted upward, the opening of the dustbin 63 can automatically tilt upward to ensure that the garbage will not fall out of the dustbin 63.

[0034] The adjusting mechanism 3 includes a rotating motor 31, which is fixedly connected to the driving housing 5. A threaded rod 32 is fixedly connected to the output shaft of the rotating motor 31. The threaded rod 32 passes through the threaded block 33 and is threadedly connected to the threaded block 33. The threaded block 33 is rotatably connected to one end of a rotating rod 34. A moving frame 35 is slidably connected to the outer surface of the rotating rod 22. The moving frame 35 is rotatably connected to the other end of the rotating rod 34. A sliding groove 8 is provided on the right surface of the driving housing 5. A slide plate 9 is slidably connected to the inner surface of the sliding groove 8. The right surface of the slide plate 9 is fixedly connected to the left surface of the threaded block 33. In order to ensure The threaded block 33 can be normally moved up and down through the threaded rod 32, and the slide plate 9 and the threaded block 33 are limited by the slide groove 8, so that the threaded block 33 can move normally. The lower surface of the driving box 5 is provided with an anti-dumping groove 16, and the inner surface of the anti-dumping groove 16 is slidably connected with a counterweight block 17. In order to ensure that the counterweight block 17 can slide more stably, the counterweight block 17 is limited by the anti-dumping groove 16, thereby effectively ensuring the stability of the counterweight block 17. The counterweight block 17 is fixedly connected to one end of the buffer spring 18, and the anti-dumping groove 16 and the buffer spring The other end of 18 is fixedly connected, and the counterweight block 17 is limited by the buffer spring 18 and the anti-dumping groove 16, so that during the normal movement of the guide robot body 1, the counterweight block 17 will not move automatically due to its own gravity and the limit of the buffer spring 18. The lower surface of the counterweight block 17 is fixedly connected to the cross bar 19, and the lower surface of the cross bar 19 is rotatably connected to the bracket 60. The upper surface of the bracket 60 is rotatably connected to the turntable 61, and the upper surface of the turntable 61 is fixedly connected to the lower surface of the threaded rod 32. The lower surface of the driving box 5 is fixedly connected to the limited position frame. 65, the inner surface of the limit frame 65 is slidably connected with the cross bar 19. Through the setting of the turntable 61, when the turntable 61 rotates, it can drive the threaded rod 32 to rotate. At this time, the rotating shaft of the rotating motor 31 is in an idling state. When the rotating motor 31 rotates, the limit frame 65 limits the cross bar 19 so that the cross bar 19 can only move horizontally and move left and right in the limit frame 65. When the cross bar 19 reciprocates left and right, it will drive the counterweight block 17 to move in the anti-dumping groove 16, so as not to affect the normal use of the rotating motor 31;

[0035] The anti-collision mechanism 4 includes a rotating ring 41, which is rotatably connected to the output shaft of the bidirectional motor 21. The outer arc surface of the rotating ring 41 is rotatably connected to a support rod 42. The shape of the support rod 42 is the same as that of the rotating rod 22. One end of the support rod 42 in a hook shape is rotatably connected to a pulley 43. By designing the support rod 42 and the moving rod 22 to be the same shape, it can be effectively ensured that when the guide robot body 1 is raised upward, the support rod 42 will not affect the raised state of the guide robot body 1. At the same time, when the guide robot body 1 is reversed backward, it can also effectively prevent collision with the corners of the display cabinet, effectively improving the stability of the guide robot body 1. A movable groove 10 is provided on the rear surface of the support rod 42, and a movable block 11 is slidably connected to the inner surface of the movable groove 10. The movable block 11 is limited by the movable groove 10, effectively ensuring the stability of the movable block 11. The rear surface of the movable block 11 is rotatably connected to one end of the fixed rod 12. An arc groove 13 is provided on the right surface of the driving box 5. The inner surface of the arc groove 13 is slidably connected to the inner surface of the movable block 11. The arc block 14 is connected, and the arc block 14 is limited by the arc groove 13, which effectively improves the stability of the arc block 14. The arc block 14 is slidably connected to the other end of the fixed rod 12. The center of the arc groove 13 is at the same point as the center of the bidirectional motor 21. By setting the center of the arc groove 13 and the center of the bidirectional motor 21 to the same point, when the output shaft of the bidirectional motor 21 rotates, the support rod 42 can be driven to rotate with the output shaft of the bidirectional motor 21 as the center, thereby realizing the support function, and the movable block 11 is fixedly connected to one end of the spring 15, and the inner surface of the movable groove 10 is fixedly connected to the other end of the spring 15. The elastic force of the spring 15 ensures that the movable block 11 will not move when it is stable. At the same time, the gravity of the navigation robot body 1 and the elastic force of the spring 15 are converted into supporting force through the arc block 14. At the same time, the supporting effect of the rotating rod 22 and the moving wheel 23 makes the navigation robot body 1 more stable. The anti-collision mechanism 4 is provided with two groups and is centrally symmetrically arranged with the center line of the navigation robot body 1 as the symmetry axis.

[0036] Working principle: when the navigation robot body 1 needs to move, the bidirectional motor 21 is started, and the output shaft of the bidirectional motor 21 rotates counterclockwise, and the output shaft drives the moving wheel 23 to rotate through the transmission belt, and the navigation robot body 1 moves forward through the rear wheel drive of the moving wheel 23. At the same time, after the moving wheel 23 rotates, the pulley 43 connected to the support rod 42 rotates, and the pulley 43 rotates, so that the navigation robot body 1 moves forward;

[0037] When the guide robot body 1 needs to clean the road surface while moving, the rotating motor 31 is started. After the output shaft of the rotating motor 31 rotates counterclockwise, the threaded block 33 limits the slide plate 9 through the slide groove 8, so that the threaded block 33 moves downward. When the threaded block 33 moves downward, the moving frame 35 is driven downward by the rotating rod 34, so that the rotating rod 22 moves in an arc shape counterclockwise with the center of the circle of the output shaft of the bidirectional motor 21 as the axis. At the same time, the connecting rod 6 drives the cleaning brush 7 to move downward. When the rotating rod 22 moves in an arc shape counterclockwise, the movable block 11 uses the elastic force of the spring 15, and when the right side of the guide robot body 1 moves upward through the rotating rod 22, the support rod 42 is always in close contact with the ground, and the connecting rod 6 is closer to the ground, so that the cleaning brush 7 can When the cleaning brush 7 rotates counterclockwise, the cleaning brush 7 will be driven to rotate counterclockwise by the counterclockwise rotation of the pulley 43, and the cleaning brush 7 will be driven to rotate counterclockwise. When the cleaning brush 7 rotates counterclockwise, the cleaning brush 7 will sweep the garbage on the ground into the garbage bin 63, and the rotating motor 31 will be turned on to drive the threaded block 33 to move upward clockwise. The threaded block 33 drives the moving frame 35 to move upward through the rotating rod 34, and drives the support rod 42 to move in an arc clockwise direction. When the garbage bin 63 moves upward through the support rod 42, the weight of the counterweight bar 64 will drive the right side of the garbage bin 63 to fall downward, leaving all the garbage in the garbage bin 63.

[0038] When the tour guide robot body 1 moves forward through the moving wheels 23, when the support rod 42 is hit by the display stand, the arc surface of the support rod 42 will be squeezed by the display stand first, and the left side of the tour guide robot body 1 will rise upward. At this time, since the tour guide robot body 1 has an inclination angle after the left side rises upward, the counterweight block 17 slides in the anti-dumping groove 16 due to its own gravity. When the counterweight block 17 slides to the right, it will drive the cross bar 19 to slide to the right. Through the connection between the cross bar 19 and the bracket 60, the bracket 60 is rotatably connected to the turntable 61. When the counterweight block 17 slides to the right, the bracket 60 will drive the turntable 61 rotates, and the turntable 61 drives the threaded rod 32 to rotate clockwise, so that the threaded block 33 moves upward. Since the center of the rotating rod 22 is concentric with the center of the circle of the bidirectional motor 21, when the threaded block 33 moves upward, the rotating rod 22 is driven by the moving frame 35 through the rotating rod 34 to drive the rotating rod 22 to make an arc motion counterclockwise, and the moving frame 35 will slide on the rotating rod 22. When the rotating rod 22 moves upward, since the rotating rod 22 contacts the ground through the gravity of the guide robot body 1, when the rotating rod 22 moves upward, the support distance of the guide robot body 1 will be expanded, so that the guide robot body 1 is not easy to tip over when a collision occurs.
