Anti-collision movable mechanism for domestic sweeping robot

Abstract

The invention discloses an anti-collision movable mechanism for a domestic sweeping robot, and relates to the technical field of domestic sweeping robots. The anti-collision movable mechanism specifically comprises a base and a shell. A soft check ring is installed on the lower side of the base. A rotating ring is installed in the middle of the base. A clamping groove is formed in the inner side of the rotating ring. A clamping ring is installed on the inner side of the clamping groove. The clamping ring is embedded and connected into the clamping groove. A wheel is installed on the inner sideof the clamping ring. A spherical shell is arranged on the inner side of the wheel. A central base is arranged in the spherical shell. Driving wheels are installed on the left side and the right sideof the central base respectively. A connecting rotating shaft is installed on the upper side of the central base. A driven wheel support is connected with the upper side of the connecting rotating shaft. According to the anti-collision movable mechanism, through a rolling structure composed of the spherical shell and the clamping ring, the device is moved; the spherical shell is overall of a spherical structure and can rotate through a built-in power system, so the whole device is driven to move.

Description

technical field [0001] The invention relates to the technical field of household sweeping robots, in particular to an anti-collision moving mechanism for household sweeping robots. Background technique [0002] Sweeping robot, also known as automatic cleaning machine, intelligent vacuum cleaner, robot vacuum cleaner, etc., is a kind of intelligent household appliances, which can automatically complete the floor cleaning work in the room by virtue of certain artificial intelligence. Ground debris is first absorbed into its own garbage storage box to complete the function of ground cleaning. Generally speaking, robots that complete cleaning, vacuuming, and mopping the floor are also collectively classified as sweeping robots. [0003] General household sweeping robots usually use two power wheels and one universal wheel to move. The two power wheels provide the power for the robot to move, and one universal wheel plays the role of steering. However, the turning radius of this ...

Problems solved by technology

[0003] General household sweeping robots usually use two power wheels and one universal wheel to move. The two power wheels provide the power for the robot to move, and one universal wheel plays the role of steering. However, the turning radius of this type of movement is relatively large. It is easy to produce dead spots for cleaning. When used in a small-area environment, there are more restrictions, and the resistance when moving is greater, resulting in more energy consumption for the robot and shorter battery life. Moreover, when the household sweeping robot is moving, it is easy to collide. onto furniture, walls, and damage the robot

[0004] The fully automatic sweeping robot disclosed in the Chinese utility model patent application publication specification CN206424042U, although the sweeping robot is provided with an ultrasonic ranging device for anti-collision, the distance between the sweeping robot and obstacles can be measured by the ultrasonic ranging device , and send the measured results to the controller, the controller guides the first servo motor to move according to the measured results, avoiding the damage caused by the hard contact of the sweeping robot. However, the sweeping robot is only equipped with an active avoidance anti-collision system. In the accidental active collision of objects, it is difficult to avoid, does not have a collision buffer structure, and has the disadvantage of being easily damaged when it is collided
