Description

Technical Field

[0001] This application relates to the field of intelligent transportation, specifically to a traffic management robot capable of rapid movement and omnidirectional turning to prevent tipping over. Background Technology

[0002] In recent years, artificial intelligence has become increasingly powerful. Currently, many cities across the country are using traffic management robots for smart urban transportation management. These robots assist traffic management departments in tasks such as traffic control at intersections, construction site alerts, pedestrian crossing guidance, and capturing illegally parked vehicles. Especially in complex urban intersections and accident-prone areas, where traffic congestion is prone to occur, using traffic management robots to replace traffic police can effectively reduce the workload of traffic police, improve traffic flow efficiency, and optimize urban road traffic order.

[0003] Currently, most traffic management robot locomotion devices have simple structures and limited functions. During operation, these robots encounter numerous obstacles, preventing them from turning freely and causing collisions that eventually lead to serious damage. The current locomotion devices for traffic management robots are mainly multi-wheeled, tracked, and bipedal. These devices can only turn or move within a certain angle, not across a 360-degree plane, thus hindering their ability to turn or move quickly and efficiently.

[0004] Multi-wheeled designs, limited by structure and size, offer advantages in navigating uneven terrain but sacrifice stability. Furthermore, multi-wheeled structures have a large turning radius and low turning efficiency. Tracked structures offer good stability and strong all-terrain adaptability, but their low speed, heavy weight, and easily worn parts mean the robot can only turn when the speeds of the two tracks differ, resulting in high turning resistance and inflexible steering. Walking locomotives, based on bionics, offer superior obstacle-crossing ability and flexibility compared to wheeled and tracked locomotives, enabling complex motion. However, the coordinated control of components is challenging, and the control and drive systems are extremely expensive.

[0005] The above-mentioned traffic management robots cannot perform emergency avoidance when encountering dangerous situations during their duties. They also cannot stand up on their own after being pushed over by external forces, tripped by obstacles, or blown over by strong winds, and require human assistance to get up. This limits the adaptability of these traffic management robots in practical applications.

[0006] Therefore, there is an urgent need for a traffic management robot with a simple control system, small footprint, low center of gravity, quick, flexible and stable steering, and anti-tipping function. Summary of the Invention

[0007] The purpose of this application is to provide a fast-moving, all-angle-turning anti-tipping traffic management robot. This device integrates anti-tipping and turning control, and has the advantages of small footprint, low center of gravity, simple control system, and fast, flexible and stable turning. It solves the shortcomings of existing traffic management robot walking devices, such as large turning radius, inflexible turning and easy to tip over.

[0008] To achieve the above objectives, this application provides the following solution:

[0009] A fast-moving, all-angle-turning anti-tipping traffic management robot includes a robot body, an ultrasonic radar, and traffic lights. The ultrasonic radar and traffic lights are both mounted on the robot body. The robot body contains a mounting plate, an equipment compartment, a power system, a voice broadcast unit, and a high-density counterweight. A solar photovoltaic panel is mounted on the top of the robot body. A battery and control unit are located in the equipment compartment. The power system includes a steering unit, a lifting unit, and a traveling unit.

[0010] The steering unit includes a steering motor, which is connected to a drive gear. The drive gear meshes with a driven gear, which is connected to a steering shaft. The steering shaft has a slot, and a sleeve is provided in the slot. The lower end of the steering shaft is connected to the travel unit. The steering unit can be controlled by the control unit to steer or to autonomously avoid obstacles in an emergency.

[0011] The lifting unit includes a lifting motor connected to a first gear, which meshes with a second gear. The second gear is connected to a drive shaft, and a sliding seat is screwed onto the drive shaft. One end of a pull rod is connected to the lower end of the sliding seat, and the other end of the pull rod is connected to the ferrule. When the robot is stationary, the lifting unit moves to lift the traveling unit into the robot body.

[0012] A further improvement is that the mounting plate divides the robot body into an upper part and a lower part. The upper part is made of waterproof and dustproof plastic synthetic material and has a protective shell with actuators and connecting parts. The equipment compartment is built into the upper part. The lower part is a hemisphere made of carbon steel sheet by stamping. It houses the high-density counterweight and the mounting bracket of the power system. The high-density counterweight is poured into the lower part in a semi-solid state and solidifies to a horizontal surface. The mounting plate has a circular hole at its geometric center, and a sleeve is installed in the circular hole. The steering shaft passes through the sleeve.

[0013] A further improvement is that the control unit adopts an embedded structure design and integrates a signal control module, a motor drive module, a voice broadcast module, a 4G / 5G module, a wireless module, and an interface module.

[0014] A further improvement is that the steering unit is also equipped with an angle detection sensor, which is mounted on the steering motor shaft and positioned below the drive gear.

[0015] A further improvement is that the driven gear is mounted on the top of the steering shaft and moves up and down with the steering shaft, and the overall length of the driving gear is greater than the height of the driven gear.

[0016] A further improvement is that the lifting unit also includes two limit switches 25, which are fixed to the mounting plate and respectively located on both sides of the sliding seat, for limiting the lifting distance of the lifting unit.

[0017] A further improvement is that the traveling unit is equipped with a traveling control motor inside and traveling wheels outside, and the traveling control motor and traveling wheels are integrated and controlled.

[0018] A further improvement is that the ultrasonic radar is installed inside the upper part, protruding from the robot body, and electrically connected to the control unit. It is used to acquire signals of obstacles within a set range and transmit the signals to the control unit.

[0019] A further improvement is that the solar photovoltaic panel is electrically connected to the battery to charge the battery.

[0020] A further improvement is that the control unit is connected to a cloud platform or mobile app via the Internet, so that the control unit can be remotely controlled by the cloud platform or mobile app.

[0021] The beneficial effects of the technical solution in this application are as follows:

[0022] 1. The fast-moving, all-angle-turning anti-fallover traffic management robot provided in this application has a simple structure and is easy to operate. It adopts a single-wheel steering method, which avoids the need for multiple wheels or double tracks to cooperate when the robot turns or walks. When the robot senses an obstacle, it can turn on the spot and quickly avoid the obstacle. It has the advantages of fast forward and backward movement, high turning efficiency, and good safety, and is not limited by the site, road and space.

[0023] 2. This traffic management robot has a high-density counterweight added to its hemispherical bottom. Utilizing the working principle of a roly-poly toy, it will not fall over when subjected to strong winds or other external forces, but will only sway, thus increasing the safety, practicality, and fun of the traffic management robot.

[0024] 3. This traffic management robot has a lifting unit that can lift the single wheel into the body when stationary. When the robot has set its direction of travel, the single wheel can turn at the highest position of the lift. After turning, it will descend to the ground and start moving. The frictional resistance during the turning process is small, making turning more convenient and flexible, reducing wear and extending the service life of the single wheel.

[0025] 4. The transmission tooth length of the drive gear is set to meet the displacement distance of the driven gear during the lifting process of the lifting unit, so that the driven gear remains in the meshing state with the drive gear and slides without disengaging, thus ensuring the reliability of accurate steering after the single wheel is lifted.

[0026] 5. This traffic management robot can display the status of traffic lights and has a voice broadcast function. It can promote traffic safety knowledge and broadcast the status of traffic lights during its duty, thereby reducing the number of times traffic participants run red lights and enhancing their safety awareness.

[0027] 6. This traffic management robot has cloud platform and mobile APP remote control functions, which can remotely control the robot's turning, walking and stationary modes, making management convenient and greatly reducing labor costs.

[0028] 7. This traffic management robot adopts a method of direct control of steering and movement by the control unit. The control system is simple and has strong overall controllability. The device can achieve all-round unobstructed steering and movement. An angle detection sensor is set on its steering motor shaft, which can set and provide feedback on the movement direction of the traffic management robot based on the rotation angle. By setting the mounting plate and pull rod, the center of gravity can be effectively lowered and the stability of walking can be improved. It is worth promoting. Attached Figure Description

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1-9As shown, this embodiment provides a fast-moving, all-angle-turning anti-tipping traffic management robot, including a robot body 1, an ultrasonic radar 2, and a traffic indicator light 3. The ultrasonic radar 2 and the traffic indicator light 3 are both mounted on the robot body 1. The robot body 1 is equipped with a mounting plate 4, an equipment compartment 5, a power system 27, a voice broadcasting unit, and a high-density counterweight 6. The top of the robot body 1 is equipped with a solar photovoltaic panel 7. The equipment compartment 5 is equipped with a battery and a control unit. The power system 27 includes a steering unit, a lifting unit, and a traveling unit 13.

[0044] The steering unit includes a steering motor 8, which is connected to a drive gear 9. The drive gear 9 meshes with a driven gear 10. The driven gear 10 is connected to a steering shaft 11. A slot is provided on the steering shaft 11, and a sleeve 12 is provided on the slot. The lower end of the steering shaft 11 is connected to a travel unit 13. The steering unit can be controlled by the control unit to steer or to autonomously avoid obstacles in an emergency.

[0045] The lifting unit includes a lifting motor 14, which is connected to a first gear 15. The first gear 15 meshes with a second gear 16, which is connected to a drive shaft 17. A sliding seat 18 is screwed onto the drive shaft 17. One end of a pull rod 19 is connected to the lower end of the sliding seat 18, and the other end of the pull rod 19 is connected to a retainer 12. When the robot is stationary, the lifting unit moves to lift the traveling unit into the robot body 1.

[0046] The robot uses a single-wheel steering mechanism, allowing it to turn on the spot and quickly avoid obstacles; it also employs a round-bottom, high-density counterweight design (the principle of a roly-poly toy) to prevent it from tipping over when in motion or at rest.

[0047] In this embodiment, the mounting plate 4 divides the robot body 1 into an upper part 20 and a lower part 21. The upper part 20 is made of waterproof and dustproof plastic synthetic material and has a protective shell with execution components and connecting components. The equipment compartment is built into the upper part 20. The lower part 21 is a hemisphere made of carbon steel sheet by stamping. It has a mounting bracket for high specific gravity counterweight and power system components. The high specific gravity counterweight is poured into the lower part 21 in a semi-solid state and solidifies to a horizontal surface. The mounting plate 4 has a circular hole at its geometric center and a sleeve 22 is installed in the circular hole. The steering shaft 11 passes through the sleeve 22.

[0048] The mounting plate 4 is circular, and the sleeve 22 is a thick cylinder with an edge extending outward from the top circumference. This edge is bonded to the mounting plate 4 for fixing the sleeve 22. A through hole is opened in the center of the sleeve 22, and the diameter of the through hole is the same as the outer diameter of the steering shaft 11. The purpose is to ensure that the steering shaft 11 moves only in a straight line when moving up and down in the sleeve 22 without swaying left and right, thereby increasing the stability of the lifting unit. The mounting plate 4 also has four identical rectangular holes located directly below the sliding seat 18, and the sliding seat 18 moves within the rectangular holes.

[0049] like Figure 4 As shown, the high specific gravity counterweight 6 is poured into the lower part 21 in a semi-solid state, and the bottom of the lower part 21 is filled in blocks. After solidification, the surface is horizontal. The filling amount of each filling block should be maintained to ensure that the robot is stable and does not tilt when it is stationary. The working principle of the self-righting toy is adopted so that the robot remains stable whether it is stationary or moving, and will not fall over under external force or strong wind.

[0050] In this embodiment, the control unit adopts an embedded structure design and integrates a signal control module, a motor drive module, a voice broadcast module, a 4G / 5G module, a wireless module, and an interface module.

[0051] The traffic management robot is equipped with traffic lights 3 in four directions, which can be set with humanized patterns and have display modes such as red light, green light, yellow flashing and countdown. It can be used for pedestrian crossing guidance as well as construction and accident scene warnings. The control unit can be set with motor drive programs to control the steering motor 8 to turn, the lifting motor 14 to lift, and the forward and backward movement of the traveling unit 13. The voice broadcast module includes a voice chip, which stores the content of the voice broadcast. The control unit is electrically connected to the voice chip to select the broadcast content of the voice broadcast module. When the robot moves, it can also remind surrounding vehicles and pedestrians to avoid the robot.

[0052] In this embodiment, the steering unit is also equipped with an angle detection sensor 23, which is mounted on the steering motor 8 shaft and positioned below the drive gear 9. This angle detection sensor 23 is a non-contact angle sensor, consisting of a rotating part and a sensing part. The rotating part is embedded in the sensing part to achieve non-contact angle detection. The rotation angle of the master and slave gears is determined based on the number of revolutions of the steering motor 8 shaft, thereby achieving full-angle control of the traffic management robot's direction of travel.

[0053] In this embodiment, the driven gear 10 is installed on the top of the steering shaft 11 and moves up and down with the steering shaft 11. During the lifting process, in order to ensure that the driving gear 9 and the driven gear 10 do not disengage, the overall length of the driving gear 9 is greater than the lifting height of the driven gear 10. Therefore, the overall length of the driving gear 9 is selected according to the lifting height of the lifting unit.

[0054] like Figure 5 , Figure 6 , Figure 7 As shown, in the lifting unit, the first gear 15 is arranged horizontally, with the shaft of the lifting motor 14 embedded below. The second gear 16 is arranged longitudinally and symmetrically on the left and right sides of the first gear 15. The first gear 15 and the second gear 16 are axially perpendicular, and both the first gear 15 and the second gear 16 are helical gears. When the lifting motor 14 rotates clockwise, the first gear 15 rotates clockwise. Through the meshing of the gear transmission teeth, the second gears 16 on both sides rotate counterclockwise with the first gear 15, and the transmission shaft 17 connected to the second gear 16 also rotates counterclockwise. When the lifting motor 14 rotates in reverse, the first gear 15 rotates clockwise, and the second gears 16 on both sides rotate clockwise accordingly, and the transmission shaft 17 connected to the second gear 16 also rotates clockwise.

[0055] The sliding seat 18 has internal threads and a circular through hole at the bottom for connecting the upper end of the pull rod 19. Starting from the center of the drive shaft 17, threads in opposite directions are symmetrically formed on both sides, with the same pitch, and they mesh with the internal threads of the sliding seat 18. The sliding seats 18 are symmetrically arranged on both sides with the center of the drive shaft 17 as the midpoint. The setting range of the threads on the drive shaft 17 meets the travel range of the sliding seats 18 on both sides, ensuring that the lifting unit can be raised and lowered into place. The internal threads of the sliding seats 18 are arranged in the same direction as the threads on the drive shaft 17 on the same side. This is so that when the drive shaft 17 rotates clockwise, the sliding seats 18 on both sides move outward synchronously and by the same distance; when the drive shaft 17 rotates counterclockwise, the sliding seats 18 on both sides move inward synchronously. When the lifting unit is raised or lowered into place, the meshing of the internal threads of the drive shaft 17 and the sliding seats 18 also restricts the lifting unit to a fixed position.

[0056] The sleeve 12 has a through hole in its center through which the steering shaft 11 passes. Four circular holes are also provided along its edge for connecting the lower end of the pull rod 19. Both ends of the pull rod 19 are designed as insertion points, which are inserted into the holes on the sleeve 12 and the sliding seat 18 and secured with pins. The purpose of the groove on the steering shaft 11 is to allow the sleeve 12 to engage with the steering shaft 11, forming a single unit. During lifting and lowering, the pull rod 19 drives the steering shaft 11 to move together.

[0057] The lifting unit is also equipped with a seated bearing 24. The bottom of the seated bearing 24 is welded or bolted to the mounting plate 4. Both ends of the drive shaft 17 pass through the seated bearing 24. The seated bearing 24 supports the drive shaft 17 to a certain height. This height allows the sliding seat 18 to slide smoothly in the rectangular hole without being affected by the frictional resistance of the mounting plate 4. This support height also ensures that the second gear 16 does not scrape the mounting plate 4 when it rotates.

[0058] In this lifting unit, two drive shafts 17 are provided, corresponding to the second gear 16. Each drive shaft 17 is equipped with two sliding seats 18 and two bearings 24. Each sliding seat 18 is connected to a tie rod 19. That is, a total of four tie rods 19 are provided to cooperate with the steering shaft 11 to jointly pull the travel unit 13 to lift. The second gear 16 is located on the outside of the sliding seats 18, and the bearings 24 are located on the outside of the second gear 16.

[0059] In this embodiment, the lifting unit also includes two limit switches 25, which are fixed to the mounting plate 4 and respectively located on both sides of one of the sliding seats 18, for limiting the lifting distance of the lifting unit. When the lifting motor 14 rotates forward, the sliding seat 18 moves outward and encounters the outer limit switch 25. The outer limit switch 25 will send a signal to the control unit, and the control unit will command the lifting motor 14 to stop rotating forward. When the lifting motor 14 rotates in reverse, the sliding seat 18 moves inward and encounters the inner limit switch 25. Similarly, it will send a positioning command to the control unit, and the control unit will command the lifting motor 14 to stop rotating in reverse.

[0060] In summary, the working process of the lifting unit can be summarized as follows: when the lifting motor 14 rotates forward or in reverse, it drives the first gear 15 and the second gear 16 to rotate. The transmission shaft 17 connected to the second gear 16 rotates accordingly. After the transmission shaft 17 rotates, the sliding seat 18, which is engaged with the thread on the transmission shaft 17, slides outward or inward at the same time, causing the pull rod 19 to open outward or tighten inward. The steering shaft 11 is fixedly connected to the pull rod 19 through the sleeve 12 and is lifted or lowered as the pull rod 19 moves, thereby realizing that the traveling unit 13 is lifted or lowered as the pull rod 19 moves outward or inward.

[0061] A motor bracket 26 is also provided on the mounting plate 4. The lifting motor 14 is fixed on the motor bracket 26. The drive gear 9 is located inside the motor bracket 26. A through shaft hole is opened on the motor bracket 26. The shaft of the lifting motor 14 passes through the through shaft hole and is connected to the drive gear 9.

[0062] In this embodiment, the traveling unit 13 has a traveling control motor inside and traveling wheels outside, with the traveling control motor and traveling wheels integrated for control. The traveling unit 13 has omnidirectional wheels and can rotate 360 ​​degrees horizontally.

[0063] The robot can turn flexibly in the following two situations:

[0064] In the first scenario, when the traffic management robot is stationary and in a standby state, the lifting unit is in the lifting position, and the traveling unit 13 is located inside the lower part 21. When a driving command is received, the traveling unit 13 can complete the turning inside the lower part 21. This reduces the friction of the traveling unit 13 when turning, enabling unobstructed turning. After the turning is completed, the lifting motor 14 starts to lower the lifting unit, so that the traveling unit 13 can contact the ground and start driving.

[0065] In the second scenario, if an obstacle appears in front of the traffic management robot while it is in motion, the robot can control its steering and move forward in place after detecting the obstacle, quickly avoiding the obstacle and preventing dangerous situations from occurring.

[0066] In this embodiment, the solar photovoltaic panel 7 is electrically connected to the battery to charge it. The battery is also electrically connected to various electrical devices inside the robot body 1 to supply power to those devices.

[0067] The ultrasonic radar 2 is located inside the upper part 20 and is electrically connected to the control unit. It is used to acquire signals of obstacles within a set range and transmit the signals to the control unit. In this embodiment, the ultrasonic radar 2 acquires obstacle information of the robot body 1 within a range of 250mm to 350mm and transmits the information to the control unit. The control unit operates the steering motor 8 to turn and avoid obstacles. When the ultrasonic radar 2 senses that there are no obstacles within a range of 250mm to 350mm, the control unit operates the traveling unit to start and move towards the target position.

[0068] In this embodiment, the control unit is connected to a cloud platform or mobile APP via the Internet, so that the control unit can be remotely controlled by the cloud platform or mobile APP, reducing the time and manpower costs of manually starting and stopping the robot.

[0069] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "horizontal", "longitudinal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0070] In the description of this application, it should be understood that, for ease of description, the terms "robot," "the robot," "traffic management robot," and "the traffic management robot" used in the specification all refer to the same type of robot, namely, the "rapidly moving, all-angle turning, anti-tipping traffic management robot" described in the subject matter of this application.
