Novel collision and obstacle avoidance structure for floor sweeping robot

Abstract

The invention discloses a novel collision and obstacle avoidance structure for a floor sweeping robot. The novel collision and obstacle avoidance structure for the floor sweeping robot is composed of at least three collision detection units, each collision detection unit comprises an arc-shaped movable cover (1) and a fixed detector (2) matched with the arc-shaped movable cover (1), and the arc-shaped movable covers (1) of all the collision detection units are combined to form a semi-circular front cover of the front end of the floor sweeping robot. Nine collision detection units are arranged, the included angle between every two adjacent collision detection units is 20 degrees, and nine sections of arc-shaped movable covers (1) of the nine collision detection units are combined to form the semi-circular front cover of the front end of the floor sweeping robot. According to the novel collision and obstacle avoidance structure for the floor sweeping robot, the semi-circular front cover is divided into nine sections of collision detection units, collision orientations can be recognized accurately and specifically by reading signals of the collision detection units, and reliable physical bases are provided for intelligent judgment and steering of the robot. A PCB insulation layer and a reverse side shielding layer are arranged on the inner side of a PCB layout layer of an interdigital capacitor, so that the working reliability of the interdigital capacitor is increased.

Description

technical field [0001] The invention relates to the field of intelligent cleaning robots, in particular to a novel collision and obstacle avoidance structure of a sweeping robot. Background technique [0002] With the continuous improvement of people's living standards, the application of smart home appliances is becoming more and more extensive, and has a very broad market prospect. Sweeping robot, also known as automatic cleaning machine, smart vacuum cleaner, robot vacuum cleaner, etc., is a kind of smart household appliances, which can automatically complete the floor cleaning work in the room by virtue of certain artificial intelligence. Generally, brushing and vacuuming are used to absorb the debris on the ground into its own garbage storage box, so as to complete the function of ground cleaning. Sweeping robots were first sold in European and American markets, and gradually entered the Chinese market with the improvement of domestic living standards. [0003] The wo...

AI Technical Summary

Problems solved by technology

[0011] A. Defects in the infrared detection method: the existing infrared detection of the front collision of the sweeping robot adopts a 3-stage (left, middle, right) infrared structure. Since the infrared emission and reception have strong directionality, therefore:

[0015] B. Defects of the front bumper collision device: due to the use of a whole piece of collision device, it can only identify whether the collision occurred on the left or right side, and cannot accurately and effectively provide the collision azimuth, and often misunderstands the obstacles directly in front. sentence
