Clean robot
Technical field
The utility model relates to clean robot, especially for the clean robot of carpet in the clean room or indoor floor.
Background technology
Along with human living standard's raising, the service type robot that is used to replace the mankind to carry out housework more and more is subjected to liking of people, and particularly the household cleaning robot has considerable market prospects.Chinese patent application number is to have disclosed a kind of common structure of present clean robot in 200810043283.2 the patent application, please refer to accompanying drawing 1, comprise circular loam cake and chassis, and being positioned at power-supply system, drive system, sensing system, cleaning systems and control system on the chassis, a side on chassis is installed a universal wheel component 11 '.During work, control system moves clean robot according to the feedback signal control-driven system of sensor-based system within the specific limits, the zone that cleaning systems cleaning clean robot moved.But adopt the clean robot of this structure to have a defective: need retreat when clean robot detects obstacle, and this moment, robot was in lower position, that is to say, robot need be when lower position retreats into the higher position, and can not cross some obstacles (as edge of carpet), thereby cause some cleaning blind areas, and then cause it not clean effectively the working region.
The utility model content
Technical problem to be solved in the utility model is to overcome existing clean robot can not cross some obstacles and cause the low defective of cleaning efficiency in fallback procedures, proposes a kind of simple in structure and can overcome the clean robot of above-mentioned defective.
The technical solution adopted in the utility model is as follows:
A kind of clean robot, comprise chassis and loam cake, and be positioned at power-supply system, drive system, sensing system, cleaning systems and control system on the chassis, one side on described chassis is equipped with universal wheel component, and the opposite side with respect to universal wheel component is installed on described chassis is equipped with wheel assembly;
Described wheel assembly comprises the back-up block that is used to lead;
Described wheel assembly and chassis are integrated;
Described wheel assembly is detachably to be installed on the chassis.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is because the opposite side with respect to universal wheel component is installed on the chassis is equipped with wheel assembly, therefore clean robot is in fallback procedures, wheel assembly can be crossed over the obstacle of certain altitude to a certain extent, make clean robot effectively cover the working region, and then improved the operating efficiency of clean robot.In addition, wheel assembly has an auxiliary support effect to clean robot, can guarantee that clean robot makes its rear portion break the barriers smoothly in the process of advancing.

The specific embodiment
Below in conjunction with the specific embodiment and contrast accompanying drawing the utility model is further elaborated.
Please refer to Fig. 2 to Fig. 4, be a preferred embodiment of the present utility model, the utility model clean robot 1 comprises loam cake and chassis 10, and be positioned at power-supply system, drive system, sensing system, cleaning systems and control system on the chassis, power-supply system is dry cell or other batteries, for clean robot provides electric energy; Drive system comprises two driving wheels 15 that are installed on the chassis 10; Cleaning systems comprise that two are installed in spin-cleaning brush 13 on the chassis 10 and the limit hairbrush 14 that is installed in chassis 10 1 sides; Sensing system is to hit the checkout gear that technology such as employing infrared ray on 16 or ultrasonic wave detect clean robot environment of living in before being installed in; Control system is carried out relevant action according to the FEEDBACK CONTROL clean robot of sensing system.
One side on the chassis 10 of the utility model clean robot is equipped with universal wheel component 11, and the opposite side that universal wheel component 11 is installed relatively on chassis 10 is equipped with wheel assembly 12.Wheel assembly 12 is removably mounted on the chassis 10, as being installed on the chassis 10 by fixed forms such as buckle or screws; Perhaps wheel assembly 12 is one-body molded with the chassis, so only needs a mold, can save certain cost.In order to make the better effects if of the crossing over blockage of clean robot when retreating, can add back-up block 120 at the side of wheel assembly 12, back-up block 120 is contract type or streamlined wheel assembly 12 sides that are attached to, for wheel assembly crossing over blockage (as carpet) when retreating provides guide effect, thereby make clean robot 1 easier crossing over blockage, and then the operating efficiency of clean robot is provided.
The utility model clean robot process of crossing over blockage in retreating is as follows:
After the sensing system of clean robot 1 senses obstacle, control system control clean robot 1 moves backward, driving wheel 15 rotates backward, driving wheel assembly 12 rotates backward, because wheel assembly 12 has certain altitude, so wheel assembly 12 can be crossed some obstacles (as edge of carpet etc.) at an easy rate; Simultaneously, wheel assembly also has an auxiliary support effect to clean robot, can guarantee that clean robot makes its rear portion break the barriers smoothly in the process of advancing.
The utility model is by having installed wheel assembly on the clean robot chassis, thereby the defective that in fallback procedures, can not cross some obstacles that can effectively avoid present clean robot to occur, thereby can clean the target area effectively, and then improve the operating efficiency of clean robot.In addition, wheel assembly has an auxiliary support effect to clean robot, can guarantee that clean robot makes its rear portion break the barriers smoothly in the process of advancing.
