Sweeping robot rolling brush working state and principle

The four-word summary of the direction of modern machine optimization is "step by step", gradually shifting from the complex coordination of circuits and structures to modular division of labor. Ensure that the different functional parts of the machine are independent and cooperate with each other. One place can still be damaged without delay. Just like the popular combination debut now, one person forgets the dance step, and the other has to hurry up. This contemporary tool of sweeping robots is particularly evident at this point.

Schematic diagram of the structure of the sweeping robot chassis

From the perspective of large structure, almost all sweeping robots on the market are a "tricycle" consisting of a universal wheel and two driving wheels. The main structure is one or two side brushes, and the garbage is rubbed into the mouth of the dusting brush to let it eat. The difference is that a smart robot can feed back the actual ground conditions through the dangling sensors and collision sensors at the bottom, and then make judgments.

It can be said that the mechanical structure determines the cleaning ability of the sweeping robot, and the update of the algorithm determines the cleaning efficiency.

Let's break the side and say:

Xiao Yan + motor, liberating hands depends on it

The sweeping robot can complete the effective cleaning, the most important thing is the vacuum roller.

Rolling brush working status

Up to now, the vacuum brush on the market has mainly undergone 3 generations of renewal. From the very beginning, it is only based on the vacuum suction structure improved by the vacuum cleaner. Later, the single roller brush is added to strengthen the cleaning ability. Until now, the mainstream double is on the market. Roller brush structure - rubber roller brush plus hair roller, face the relative rotation of the suction port, with the side brush, and finally achieve the purpose of system cleaning.

Double rolling brush gearbox

As shown above, the gear with metal bearing is a rubber roller brush and a capillary roller brush. Both roller brushes are subjected to the same motor. A gear box is provided, which not only changes the rotational speed of the two roller brushes, but also Can absorb garbage in the opposite direction. (Do you think this part is shot like the opening animation of many movies?)

Please reverse the car. Reversing, please pay attention

After removing the bumper in front of the sweeping robot, we can visually see the anti-collision design inside.
