Description

Technical Field

[0001] This utility model belongs to the field of projection devices, specifically relating to a side-standing robot-following warning projection device. Background Technology

[0002] A standby robot is an intelligent device that combines robotics, sensors, computer vision, and artificial intelligence. It is mainly used to provide tasks such as safety protection, warning, navigation, or guidance. Its working principle is usually to perceive the environment through various sensors and make corresponding decisions or actions based on the perceived information.

[0003] The existing side-by-side robot warning projection devices have relatively fixed projection angles, making it difficult to adjust the position of the warning projection device to follow the movement of pedestrians on site. This results in a limited range of application scenarios. Furthermore, the projection devices equipped with facial recognition systems have poor flexibility in actual use when rotating and following the projection via motor drive, and it is also difficult to perform follow-up warning projections on a large number of pedestrians.

[0004] Therefore, to address the problem that existing side-by-side robot warning projection devices are difficult to adjust in multiple angles to follow pedestrian movements during use, a side-by-side robot following warning projection device is developed. By adding horizontal and vertical rotation adjustment structures to the warning projection device, the flexibility of the side-by-side robot warning projection device during use can be effectively improved. It can also work with the facial recognition system on the projector to enable the projector to follow pedestrians and perform flexible projection warning work. Utility Model Content

[0023] Please see Figures 1-5This utility model provides an embodiment of a robot-following warning projection device, comprising a mounting base 1, a following frame 2, and a flipping frame 3, and further comprising a first servo motor 6, a second servo motor 17, a first gear 7, a second gear 13, a transmission belt 14, and a third gear 16. A second through hole 11 is provided at the upper end of the mounting base 1. A connecting post 12 is fixedly connected to the lower end of the following frame 2, and the lower end of the connecting post 12 passes through the second through hole 11 and is fixedly connected to the second gear 13. Rotating sleeves 20 are fitted onto the connecting shafts at both ends of the flipping frame 3, and a fourth gear 18 is fixedly connected to the right end of the rotating sleeve 20. The rotating sleeve 20 is rotatably mounted on the following frame 2. The front and rear ends of the mounting base 1 are provided with a first groove 9. The lower edge of the first groove 9 is provided with a first through hole 10. The lower end of the mounting base 1 is equipped with a first servo motor 6. The output end of the first servo motor 6 passes through the first through hole 10 and is fixedly connected to a first gear 7. The right end of the following frame 2 is provided with a third through hole 15. The inner wall of the right end of the following frame 2 is fixedly connected to a second servo motor 17. The output end of the second servo motor 17 passes through the third through hole 15 and is fixedly connected to a third gear 16. The outer walls of the third gear 16 and the fourth gear 18 are fitted with a transmission belt 14.

[0024] The first servo motor 6 drives the first gear 7, which in turn drives the second gear 13 to rotate precisely. This drives the following frame 2 to rotate and adjust along the inner wall of the second through hole 11, thereby adjusting the horizontal multi-angle adjustment of the projector body 4. This is done in conjunction with the person recognition system on the projector body 4 to adjust the horizontal projection angle of the projector body 4. Meanwhile, the second servo motor 17 drives the third gear 16, which in turn drives the transmission belt 14 to drive the fourth gear 18 to adjust the vertical multi-angle adjustment along the inner wall of the following frame 2. This assists the person recognition system on the projector body 4 in adjusting the vertical projection angle of the projector body 4.

[0025] Please see Figures 3-5 In this embodiment, feet 8 are fixedly connected to the four corners of the lower end of the mounting base 1. The first groove 9, the second through hole 11 and the first through hole 10 are interconnected. In use, the feet 8 can facilitate the user to assemble the mounting base 1 onto the side-standing robot, thereby improving the ease of assembly. The front and rear ends of the flip frame 3 are provided with mounting grooves 19. The projector body 4 is fixedly connected in the mounting grooves 19. In use, the flip frame 3 can support and install the projector body 4 to assist the projector body 4 in multi-angle rotation adjustment.

[0026] Please see Figures 3-4In this embodiment, the second gear 13 and the first gear 7 are both disposed on the inner wall of the first groove 9. The protective shell 5 is installed on the right end of the following frame 2. In use, the protective shell 5 can cover and protect the third gear 16, the fourth gear 18, and the transmission belt 14 to prevent them from being affected by foreign objects. The upper and lower ends of the second gear 13 and the first gear 7 are in contact with the upper and lower ends of the first groove 9. The third gear 16, the fourth gear 18, and the transmission belt 14 are all disposed on the inner wall of the protective shell 5. In use, the transmission belt 14 can assist the third gear 16 and the fourth gear 18. 8. Stable transmission is achieved. The second gear 13 meshes with the first gear 7, and the third gear 16 and the fourth gear 18 mesh with the transmission belt 14. In use, the meshing second gear 13 and the first gear 7, the third gear 16, the fourth gear 18 and the transmission belt 14 can stably drive the following frame 2 and the projector body 4 to rotate and adjust at multiple angles. The lower end of the following frame 2 fits against the upper end of the mounting base 1. The foot 8 is installed on the side-by-side robot by bolts. In use, the foot 8 installed by bolts makes it easy for the user to assemble the mounting base 1 onto the side-by-side robot.

[0027] Before use, the mounting base 1 is assembled onto the robot by bolts, and the human face recognition system in the projector body 4 identifies pedestrians on the work site.

[0028] Next, the first servo motor 6 drives the first gear 7 to rotate, thereby driving the second gear 13 to rotate precisely, which in turn drives the following frame 2 and the connecting column 12 to rotate and adjust along the inner wall of the second through hole 11, so as to assist the following frame 2 and the projector body 4 in multi-angle horizontal adjustment.

[0029] Then, the second servo motor 17 drives the third gear 16 to drive the transmission belt 14 to drive the fourth gear 18 to rotate, so as to drive the flip frame 3 to make multi-angle vertical adjustments along the inner wall of the following frame 2, so as to assist the person recognition system on the projector body 4 to adjust the vertical projection angle of the projector body 4.

[0030] Through the above steps, the first servo motor 6 drives the first gear 7, which in turn drives the second gear 13 to rotate precisely. This drives the following frame 2 to rotate and adjust along the inner wall of the second through hole 11, thereby adjusting the horizontal multi-angle adjustment of the projector body 4. This works in conjunction with the person recognition system on the projector body 4 to adjust the horizontal projection angle of the projector body 4. Meanwhile, the second servo motor 17 drives the third gear 16, which in turn drives the transmission belt 14 to drive the fourth gear 18, to perform vertical multi-angle adjustment along the inner wall of the following frame 2. This assists the person recognition system on the projector body 4 in adjusting the vertical projection angle of the projector body 4. This solves the problem that existing side-standing robot warning projection devices are difficult to use for multi-angle rotation adjustment while following pedestrian activities.
