Description

Technical Field

[0001] This utility model relates to the field of obstacle avoidance robot technology, specifically to an intelligent obstacle avoidance robot. Background Technology

[0002] Robot obstacle avoidance technology is increasingly widely used in modern society, enabling robots to autonomously avoid obstacles in complex environments and ensure safe operation. The principles of robot obstacle avoidance include sensor technology, obstacle detection, and path planning. The foundation of robot obstacle avoidance is sensor technology. Robots typically use various sensors to acquire information related to their environment, such as sound, vision, and tactile sensors. Among these, ultrasonic sensors and infrared sensors are the most common. Infrared sensors detect the presence of obstacles by monitoring the intensity of infrared radiation. The robot emits infrared signals; when these signals encounter an object, the signal intensity changes, and the robot detects this change to determine the presence of an obstacle. Once the robot receives information from the sensors, the next step is obstacle detection. By analyzing the data from the sensors, the robot can determine the obstacle's position, distance, and shape.

[0003] Existing intelligent obstacle avoidance robots mostly have their infrared sensors directly installed inside the robot body. This requires disassembling the entire robot to inspect and maintain the infrared sensors, resulting in low inspection and maintenance efficiency. Furthermore, since the infrared sensors are located outside the robot, they are easily damaged when the robot tipes over, causing errors in obstacle avoidance. Therefore, we need to propose an intelligent obstacle avoidance robot. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent obstacle avoidance robot that uses a snap-fit ​​assembly to snap an infrared sensor into the interior of a mounting post, preventing the infrared sensor from detaching from the mounting post. Protective components and two sets of side baffles are used to protect the infrared sensor, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent obstacle avoidance robot, comprising an obstacle avoidance robot body and an infrared sensor, wherein a mounting post is fixedly provided on the upper surface of the obstacle avoidance robot body, the infrared sensor is snapped into the interior of the mounting post, and a placement groove for accommodating the infrared sensor and the snapping assembly is provided on the upper surface of the mounting post.

[0006] The upper surface of the mounting post is provided with a snap-fit ​​assembly for quick installation of the infrared sensor;

[0007] Inside the placement slot and on the side of the infrared sensor, there is a protective component for reducing the impact force on the infrared sensor.

[0008] Preferably, the snap-fit ​​assembly includes a mounting base, snap-fit ​​blocks, a swing plate, and a slanted compression spring. The infrared sensor is fixedly mounted on the upper surface of the mounting base. Two sets of snap-fit ​​blocks are provided, and the two sets of snap-fit ​​blocks are symmetrically arranged on both sides of the mounting base. The upper surface of the mounting column is provided with vertical sliding grooves corresponding to the two sets of snap-fit ​​blocks. The inside of the mounting column and on the side of the two sets of vertical sliding grooves are provided with horizontal sliding grooves corresponding to the snap-fit ​​blocks.

[0009] Preferably, there are two sets of swing plates and oblique compression springs. The two sets of swing plates are symmetrically rotated and disposed on the side wall of the vertical moving groove. One end of each set of oblique compression springs is fixedly connected to the lower surface of the corresponding swing plate, and the other end of each set of oblique compression springs is fixedly installed inside the vertical moving groove. The two sets of horizontal moving grooves are connected to the corresponding vertical moving grooves. The two sets of vertical moving grooves are opened in the shape of an inverted trapezoid, and the lower end of the vertical moving groove corresponds to the snap-fit ​​block.

[0010] Preferably, the protective assembly includes a telescopic sleeve, a connecting post, a snap-fit ​​post, and a compression spring. The connecting post is fixedly installed on the side of the infrared sensor, and the snap-fit ​​post is fixedly connected to the side of the connecting post away from the infrared sensor.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses a snap-fit ​​assembly to snap the infrared sensor into the mounting post, preventing the infrared sensor from detaching from the mounting post. By pressing the swing plate downwards to compress the inclined spring, the infrared sensor can be moved upwards to remove it for testing and maintenance, thereby improving the efficiency of infrared sensor testing and maintenance.

[0016] The infrared sensor is protected by protective components and two sets of side baffles. The two sets of side baffles prevent foreign objects from hitting the infrared sensor and damaging it. When the obstacle avoidance robot tilts, the infrared sensor will squeeze the connecting column when it comes into contact with the ground, thereby pulling the infrared sensor into the storage slot and protecting it, thus preventing errors in obstacle avoidance by the intelligent obstacle avoidance robot.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, those skilled in the art who have not made any innovative embodiments are all within the protection scope of the present utility model.

[0024] This utility model provides: an intelligent obstacle avoidance robot, such as... Figure 1-4 As shown, the obstacle avoidance robot body 1 and infrared sensor 8 are included. A mounting post 3 is fixedly installed on the upper surface of the obstacle avoidance robot body 1. The infrared sensor 8 is snapped into the inside of the mounting post 3. The upper surface of the mounting post 3 is provided with a placement groove 2 for accommodating the infrared sensor 8 and the snapping assembly.

[0025] The upper surface of the mounting post 3 is provided with a snap-fit ​​assembly for quick installation of the infrared sensor 8;

[0026] Inside the placement slot 2 and on the side of the infrared sensor 8, there is a protective component to reduce the impact force on the infrared sensor 8. The infrared sensor 8 is snapped into the mounting post 3 by a snap-fit ​​component, which prevents the infrared sensor 8 from detaching from the mounting post 3. By setting up the protective component and two sets of side baffles 21 to protect the infrared sensor 8, the detection and maintenance efficiency of the infrared sensor 8 is improved, and the damage to the infrared sensor 8 caused by bumps and knocks is prevented from causing the intelligent obstacle avoidance robot to be unable to avoid obstacles normally.

[0027] Preferably, the snap-fit ​​assembly includes a mounting base 7, snap-fit ​​blocks 11, a swing plate 19, and a slanted compression spring 20. The infrared sensor 8 is fixedly mounted on the upper surface of the mounting base 7. Two sets of snap-fit ​​blocks 11 are provided, and the two sets of snap-fit ​​blocks 11 are symmetrically arranged on both sides of the mounting base 7. The upper surface of the mounting column 3 is provided with vertical moving grooves 13 corresponding to the two sets of snap-fit ​​blocks 11. The interior of the mounting column 3 and the sides of the two sets of vertical moving grooves 13 are provided with horizontal moving grooves 12 corresponding to the snap-fit ​​blocks 11. By setting the infrared sensor 8 on the upper surface of the mounting base 7 and snapping it into the vertical moving grooves 13 through the two sets of snap-fit ​​blocks 11, and by providing the horizontal moving grooves 12, it is ensured that the mounting base 7 and the infrared sensor 8 as a whole can move into the placement groove 2.

[0028] Furthermore, two sets of swing plates 19 and oblique compression springs 20 are provided. The two sets of swing plates 19 are symmetrically rotated and arranged on the side wall of the vertical moving groove 13. One end of each set of oblique compression springs 20 is fixedly connected to the lower surface of the corresponding swing plate 19, and the other end of each set of oblique compression springs 20 is fixedly installed inside the vertical moving groove 13. The two sets of horizontal moving grooves 12 are connected to the corresponding vertical moving grooves 13. The two sets of vertical moving grooves 13 are both opened in an inverted trapezoidal shape, and the lower end of the vertical moving groove 13 corresponds to the snap-fit ​​block 11. When the mounting base 7 enters the placement groove 2 through the vertical moving groove 13, the mounting base 7 squeezes the four sets of swing plates 19. The four sets of swing plates 19 compress the oblique compression springs 20 and approach the inner wall of the vertical moving groove 13, thereby ensuring that the snap-fit ​​blocks 11 on both sides of the mounting base 7 can enter the vertical moving groove 13. When the mounting base 7 wants to move upward, the two sets of vertical moving grooves 13 will be blocked by the four sets of swing plates 19, thereby preventing the infrared sensor 8 from detaching from the placement groove 2.

[0029] Furthermore, the protective components include a telescopic sleeve 10, a connecting post 14, a locking post 15, and a compression spring 16. The connecting post 14 is fixedly installed on the side of the infrared sensor 8, and the locking post 15 is fixedly connected to the side of the connecting post 14 away from the infrared sensor 8. The telescopic sleeve 10 is slidably sleeved on the outer arc surface of the connecting post 14 and the locking post 15. The compression spring 16 is located on the side of the locking post 15 away from the connecting post 14. The connecting post 14 and the locking post 15 slide inside the telescopic sleeve 10. When the infrared sensor 8 is placed inside the placement slot 2, the telescopic sleeve 10 contacts the inner wall of the placement slot 2 under the action of the compression spring 16. When the obstacle avoidance robot body 1 tilts, the infrared sensor 8 contacts the ground and moves into the telescopic sleeve 10 by squeezing the compression spring 16 through the connecting post 14, thereby ensuring that the infrared sensor 8 is retracted into the placement slot 2 and thus preventing the infrared sensor 8 from being damaged by impact.

[0030] It is worth noting that the telescopic sleeve 10 has an inner moving groove 17 corresponding to the locking post 15, and the telescopic sleeve 10 has an outer moving groove 18 corresponding to the connecting post 14 at one end near the infrared sensor 8. The connecting post 14 and the locking post 15 move inside the inner moving groove 17, and the diameter of the locking post 15 is larger than that of the connecting post 14. The connecting post 14 extends and retracts through the outer moving groove 18, and the locking post 15 is locked by the outer moving groove 18, thereby preventing the connecting post 14 from detaching from the inside of the telescopic sleeve 10.

[0031] Specifically, two sets of side baffles 21 are symmetrically arranged on the outer arc surface of the mounting column 3 and on both sides of the placement groove 2. The two sets of side baffles 21 do not contact the mounting base 7 and the infrared sensor 8. A locking nut 9 is provided on the upper surface of the infrared sensor 8. The distance that one end of the infrared sensor 8 extends exceeds the side baffle 21, thereby ensuring the detection stability of the infrared sensor 8 and preventing the side baffle 21 from exceeding the infrared sensor 8 and blocking part of the detection range of the infrared sensor 8. The side baffle 21 is set to prevent foreign objects from hitting the sides of the infrared sensor 8. The locking nut 9 is set to facilitate the electrical connection of the infrared sensor 8 to the obstacle avoidance robot body 1.

[0032] In addition, a robot base 5 is fixedly installed on the lower surface of the obstacle avoidance robot body 1, and several sets of universal wheels 6 are installed at the bottom of the robot base 5. A display screen 4 is installed on the upper surface of the mounting column 3. The universal wheels 6 facilitate the effective movement of the obstacle avoidance robot body 1 to avoid obstacles, and the display screen 4 facilitates people's observation and operation.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
