Example one

Fig. 1 to 7 show a first embodiment of the present invention. Referring to fig. 1 and 5, the cleaningrobot 100 includes abody 110. The walking module, which supports thebody 110 and moves the cleaningrobot 100 on the working surface, includes a driving motor and a plurality of walking assemblies, in this embodiment, the walking assemblies optionally include two drivingwheels 111. The control module, which has an integrated circuit board for connecting and controlling the functional modules, may control the cleaningrobot 100 to travel within a preset work area, and control thecleaning module 120 to perform a cleaning task. The bottom of thebody 110 is provided with acavity 112, and thecavity 112 is opened toward the working surface, and at least partially receives thecleaning module 120 from above thecleaning module 120. Thecleaning module 120 is used for cleaning a working surface, and thecleaning module 120 includes apivot bracket 130, and thepivot bracket 130 is installed in thecavity 112 through apivot part 150 and is detachably connected with the main body of themain body 110. Thepivot part 150 includes afirst pivot shaft 151, thefirst pivot shaft 151 is substantially parallel to the longitudinal axis of thebody 110, and the connection position of thepivot part 150 is substantially located at the geometric center of thecleaning module 120. Thecleaning module 120 can swing around thefirst pivot shaft 151 under the reaction force generated by the contact with the working surface, so that thecleaning module 120 is kept to adapt to the working surfaces with different heights relative to the machine body, and the balance of two sides of thefirst pivot shaft 151 is automatically adjusted by swinging around thefirst pivot shaft 151, so that thecleaning module 120 is ensured to be in full contact with the working surface. Thecleaning module 120 includes alifting mechanism 140 for connecting the cleaning assembly and moving the cleaning assembly up and down under the control of the control module. An alternative cleaning assembly is amop plate 160, where themop plate 160 has a removable wiper element, and the wet mop function is achieved by changing the wetness of the wiper element. For example, theliquid tank 180 may be disposed in thebody 110 to supply water to the wipers, or the wipers with different humidities may be replaced to realize dry-mopping and wet-mopping of thecleaning module 120; the cleaning component can also be a rolling brush for executing cleaning tasks, which is not taken as a limitation of the utility model. In the embodiment of the present invention, thecleaning module 120 performs the floor mopping function as an example.

Thecleaning module 120 of thecleaning robot 100 includes apivot bracket 130 connected to the chassis of themain body 110 by apivot part 150 of thepivot bracket 130. Referring to fig. 2 and 3, thepivot bracket 130 is disposed in a lateral direction of thecleaning robot 100, substantially parallel to a lateral axis of thecleaning robot 100, which is substantially perpendicular to a traveling direction of the cleaning robot. Thepivot part 150 is provided at the center of thepivot bracket 130 to ensure that thecleaning module 120 is in a balanced state in a free state. Thepivot part 150 includes afirst pivot shaft 151, thefirst pivot shaft 151 being substantially coincident with a longitudinal axis of thecleaning robot 100, the longitudinal axis of thecleaning robot 100 being substantially parallel to a traveling direction thereof. Two first mountingholes 131 are disposed along a longitudinal axis of thepivot bracket 130 for mounting thefirst pivot shaft 151, the longitudinal axis of thepivot bracket 130 being substantially coincident with the longitudinal axis of thecleaning robot 100. The pivotingpart 150 further includes asecond pivot shaft 152, thesecond pivot shaft 152 and thefirst pivot shaft 151 are substantially located on the same horizontal plane and perpendicular to each other, and thefirst pivot shaft 151 and thesecond pivot shaft 152 are sleeved and combined through a cross joint 153 to form the pivotingpart 150. Referring to fig. 6, a groove for receiving afirst pivot shaft 151 and asecond pivot shaft 152 is disposed on a top portion of thecavity 112 corresponding to thepivot part 150, that is, a chassis of thebody 110, the pivot shafts being rotatable relative to the groove, thecleaning module 120 being hinged to the chassis of thebody 110 through thepivot part 150 to achieve a pivotal connection between thecleaning module 120 and the chassis of thebody 110, thecleaning module 120 being pivotable about thefirst pivot shaft 151. When the cleaningrobot 100 performs mopping operation, the driving force often fails to overcome the resistance of the mop cloth, so that the wheels slip and the robot runs askew. The reason for this phenomenon is that most of the reasons are that the manufacturing error of the whole machine assembly easily causes thefloor mopping plate 160 to contact the working surface only at one side, the friction resistance generated by the large pressure at one side of thefloor mopping plate 160 contacting the working surface is large, the driving force at the same side is large, and when the driving force provided by thedriving wheel 111 cannot drive thefloor mopping plate 160, the driving wheel slips; the driving force of thedriving wheel 111 required by the side of themop plate 160 which is not in good contact with the working surface is small, and the driving force is larger than the friction resistance of the mop plate, so that the problem of slipping does not occur, and therefore, when one side of thedriving wheel 111 slips and the other side of thedriving wheel 111 does not slip, the phenomenon that the machine runs askew is easily caused. The ability of thecleaning module 120 to pivot left and right relative to the chassis thus overcomes the problem of a floor scrubbing 160 that is not in balanced contact with the work surface due to assembly tolerances. In addition, thecleaning module 120 may swing around thesecond pivot shaft 152 to ensure that thecleaning module 120 is balanced forward and backward in the traveling direction of thecleaning robot 100, achieving a uniform cleaning effect. The pivot connection replaces rigid connection, so that the flexibility of thecleaning module 120 in the working state is improved, the self balance force can be adjusted in real time according to the condition of the working surface, and the dynamic balance of thecleaning module 120 in contact with the working surface is achieved.

In this embodiment, thecleaning module 120 of thecleaning robot 100 has a rectangular shape, and is disposed at the front side of the bottom of thebody 110, substantially parallel to the rotation axes of the two drivingwheels 111.

Ensuring that the cleaningrobot 100 promotes the trafficability of thecleaning robot 100 by changing the height of the cleaning assembly when the cleaningrobot 100 encounters an obstacle or does not need to perform a cleaning task, and avoiding the occurrence of secondary contamination. The pivotingbracket 130 is fixedly connected with alifting mechanism 140 of thecleaning module 120, wherein thelifting mechanism 140 includes a liftingmotor 141 and a transmission mechanism, and the liftingmotor 141 drives the transmission mechanism to drive the cleaning assembly to move in the height direction. The transmission mechanism comprises alifting bracket 142, and two ends of the pivotingbracket 130 are fixedly connected with the running guide rail of thelifting bracket 142. The lower end of thelifting bracket 142 is provided with a receivingplate 143 for installing the moppingfloor 160, the moppingfloor 160 is detachably connected with the receivingplate 143, and the optional connection mode is absorbed by anabsorption piece 162. The elevatingmotor 141 is connected to thepower supply module 170 in the main body of themain body 110 through anelectrical connection wire 171 or is connected to the power supply module via the control module, and the optionalelectrical connection wire 171 may include various kinds of wire harnesses for connecting the main body of the main body to the cleaning module. When thelifting mechanism 140 works, the control module controls thepower supply module 170 to supply power to the liftingmotor 141. The cleaningrobot body 110 further includes aliquid tank 180 in the body, the control module controls theliquid tank 180 to supply liquid to thecleaning module 120 when thecleaning module 120 performs wet cleaning, and theliquid tank 180 is installed in the body of thebody 110 and connected to thecleaning module 120 through aflexible conduit 181.

Referring to fig. 7, throughholes 113 are provided between thecavity 112 and the interior of thebody 110, and the number of the throughholes 113 is not limited. The wire harness and theconduit 181 inside thebody 110 can be connected to thecleaning module 120 through the throughhole 113 via thecavity 112, so that thebody 110 can control thecleaning module 120 to perform cleaning work with various functions. Meanwhile, in order to realize the function that thecleaning module 120 can swing flexibly relative to the main body of thebody 110, theelectrical connection wire 171 and theguide pipe 181 are made of flexible materials, and the flexibleelectrical connection wire 171 and theguide pipe 181 can deform along with the swinging of thecleaning module 120 without limiting the movement of thecleaning module 120 in thecavity 112. The combination of the pivotingbracket 130 and thelifting mechanism 140 enables the cleaning assembly to be actively lifted according to the working conditions, and can be adjusted in a small range by the reaction force generated by the contact with the working surface, thereby improving the self-adaptive function of thecleaning robot 100.

The flexible material, optionally a flexible gasket, is disposed in thecavity 112 where contact is made with thecleaning module 120, allowing both pivoting of thecleaning module 120 and closing of the gap. The flexible gasket reduces noise of thecleaning robot 100 and reduces a probability of malfunction while buffering the impact of theindependent cavity 112 with thecleaning module 120, and the closeability of the gap can prevent dust and dirt from entering theindependent cavity 112 to some extent and maintain the interior of themain body 110 clean.

The receivingplate 143 is driven by the liftingmotor 141 of thelifting mechanism 140 to drive the moppingboard 160 to move up and down through the transmission mechanism. The receivingplate 143 is detachably attached to thefloor 160 by twoside attaching members 162, and the attachingmembers 162 can be magnetic blocks. Apivot part 150 is arranged between thebearing plate 143 at the bottom of thelifting mechanism 140 and the moppingfloor 160, thepivot part 150 comprises athird pivot shaft 154, and the axis of thethird pivot shaft 154 is approximately coincident with the longitudinal axis of thecleaning robot 100.
