The water absorbing assembly 46 is mounted on the second bracket 14, the second lifting assembly 90 is mounted on the second bracket 14, and the dust pushing assembly 48 is mounted on the second lifting assembly 90. The gravity center point is located on the first support 32, the gravity center point is the gravity center of the first support 32, the second support 14, the middle sweeping frame 16, the rolling brush assembly 42, the side brush assembly 44, the water absorbing raking assembly 46, the dust pushing assembly 48 and the second lifting assembly 90, and the first support 32, the second support 14, the middle sweeping frame 16, the rolling brush assembly 42, the side brush assembly 44, the water absorbing raking assembly 46, the dust pushing assembly 48 and the second lifting assembly 90 can be lifted synchronously. When the second lifting assembly 90 drives the water absorption scraping assembly 46 and the dust pushing assembly 48 to lift, the water absorption scraping assembly 46 and the dust pushing assembly 48 swing relative to the first support 32 through the second support 14.

The blocking portion 324 has a limiting effect on the second support 34, and when the support body 322 is pulled up by the first flexible connector 14, the second support 34 is prevented from swinging downward in the past, and the dust pushing assembly 48 and the water sucking assembly 46 are prevented from not being separated from the ground.

Since the roller brush assembly 42 and the side brush assembly 44 are directly mounted on the first bracket 32, and the dust-pushing assembly 48 and the water-sucking assembly 46 are indirectly mounted on the second bracket 34, the first bracket 32 is subjected to a large force, and the first bracket 32 is easily deformed. In one embodiment, the base 30 is provided with a support wheel 38, and the support wheel 38 supports the base 30 to prevent the first support 32 from deforming. Specifically, the support wheels 38 are mounted on the bracket body 322. The support wheels 38 are universal wheels, and the traveling wheels 60 include guide wheels located in front of the cleaning robot 100 in the forward direction and rear wheels located behind the cleaning robot 100 in the forward direction.

Referring to fig. 8 to 10, in an embodiment, the second bracket 34 swings up and down along a vertical direction. The cleaning robot 100 further comprises a second lifting assembly 90, the second lifting assembly 90 is disposed on the chassis 50, and the second lifting assembly 90 is in transmission connection with the dust pushing assembly 48 and the water absorbing rake assembly 46 to drive the dust pushing assembly 48 and the water absorbing rake assembly 46 to alternatively lift. Specifically, the second lifting assembly 90 includes a first fixed seat 91, a second fixed seat 92, a guide post 93, an elastic element 94, a second driving element 95, and a second flexible connecting element 96; the first fixing seat 91 is mounted on the base 30, the guide post 93 is mounted on the first fixing seat 91, the second fixing seat 92 is movably connected to the guide post 93, the second fixing seat 92 is connected to the dust pushing assembly 48, the second driving element 95 is mounted on the second fixing seat 92, one end of the second flexible connecting piece 96 is in transmission connection with the second driving element 95, the other end of the second flexible connecting piece 96 is fixed, the elastic element 94 abuts against the second fixing seat 92, and the elastic element 94 can push the fixing seats to abut against the first fixing seat 91; the second fixing base 92 can be driven to move along the guide post 93 relative to the first fixing base 91 by the telescopic driving of the second driving element 95.

Wherein the guide post 93 is used for limiting and guiding the moving path of the second fixed seat 92. The second drive element 95 may be an electric or pneumatic cylinder or an electric motor or the like. The second flexible connecting element 96 is a pull rope, a steel wire rope or the like, and the material of the pull rope can be plastic, metal or the like. The elastic member 94 is a spring, and the other end of the elastic member 94 is fixed to the first fixing base 91 or the cleaning robot. Can promote second fixing base 92 through the spring and paste first fixing base 91 closely, the spring has the effect of supporting to second fixing base 92, and can make dirt push away subassembly 48 and ground and keep invariable pressure, ensures that dirt pushes away subassembly 48 and has better cleaning effect. In addition, the spring also has a buffering function, so that the dust pushing assembly 48 is further prevented from being in rigid contact with the ground.

The principle that the second lifting assembly 90 drives the dust pushing assembly 48 and the water absorbing rake assembly 46 to alternatively lift is as follows: the dust pushing assembly 48 and the water absorbing assembly 46 are both located at the bottom of the chassis 50, in an initial state, the dust pushing assembly 48 is closer to a cleaning target relative to the water absorbing assembly 46, the dust pushing assembly 48 is in contact with the cleaning target, and due to the fact that the dust pushing assembly 48 is in contact with the cleaning target, the water absorbing assembly 46 is tilted, and the water absorbing assembly 46 is separated from the cleaning target. I.e., the dirt-pushing assembly 48 is in contact with the ground, while the suction assembly 46 is out of contact with the ground. Specifically, in the initial state, the first driving element 12 pulls the first bracket 32 to be lifted through the first flexible connector 14, but the second driving element 95 brings the dust pushing assembly 48 into contact with the cleaning object by controlling the amount of extension and retraction of the second flexible connector 96. Alternatively, the first drive element 12 pulls the first bracket 32 down through the first flexible linkage 14, but the second drive element 95 brings the dust push assembly 48 into contact with the cleaning target by controlling the amount of extension and retraction of the second flexible linkage 96.

Then, the second driving element 95 pulls the second flexible connecting element 96, the second flexible connecting element 96 pulls the second fixed seat 92, and the second fixed seat 92 compresses the elastic element 94, so as to drive the dust pushing assembly 48 to be separated from the contact with the cleaning target, and as the dust pushing assembly 48 is separated from the contact with the cleaning target, namely the dust pushing assembly 48 is separated from the contact with the ground, the water absorbing rake assembly 46 falls under the action of self gravity and contacts with the cleaning target, and at this time, the water absorbing rake assembly 46 can absorb water to clean the cleaning target. When the second driving element 95 extends the second flexible connecting element 96, under the self-weight action of the dust pushing assembly 48 and the second fixing seat 92 and the thrust of the elastic element 94, the second fixing seat 92 is tightly attached to the first fixing seat 91, the dust pushing assembly 48 is also contacted with the cleaning target, the water absorbing rake assembly 46 is lifted again, the water absorbing rake assembly 46 is separated from the cleaning target, and therefore the dust pushing assembly 48 can clean the garbage of the cleaning target.

It will be appreciated that, depending on the actual requirements, the initial condition may also be that the wiper assembly 46 is in contact with the cleaning target, while the dirt-pushing assembly 48 is not in contact with the cleaning target.

In one embodiment, the first driving element 12 can control the amount of extension and retraction of the first flexible connecting element 14 to control the lifting and lowering of the first support 32, and the second driving element 95 can control the amount of extension and retraction of the second flexible connecting element 96 to simultaneously contact the water absorbing assembly 46 and the dust pushing assembly 48 with the cleaning object, or simultaneously separate the water absorbing assembly 46 and the dust pushing assembly 48 from the cleaning object. Specifically, the second driving element 95 controls the extension amount of the second flexible connecting member 96, so that the distances between the dust pushing assembly 48, the water absorbing raking assembly 46 and the cleaning target are equal, at this time, under the driving of the first driving element 12, if the first support 32 is lifted to a certain degree, the dust pushing assembly 48 and the water absorbing raking assembly 46 are both separated from the contact with the cleaning target, and if the first support 32 is lowered to a certain degree, the dust pushing assembly 48 and the water absorbing raking assembly 46 are both in contact with the cleaning target.

In the cleaning robot 100 of the present embodiment, the driving of the second driving element 95, the transmission of the second flexible connecting element 96 and the elastic force of the elastic element 94 enable the water-absorbing assembly 46 and the dust-pushing assembly 48 to be used alternatively without disassembling, thereby facilitating the operation. The elastic element 94 can generate a supporting force for the dust pushing assembly 48, the elastic element 94 can enable the dust pushing assembly 48 to keep constant pressure with a cleaning target, and the elastic element 94 and the second flexible connecting piece 96 have a buffering effect, so that the dust pushing assembly 48 and the cleaning target can be prevented from being in rigid contact, an obstacle can be quickly crossed, and the dust pushing assembly 48 and other parts cannot be damaged.

Since the dust pushing assembly 48 is typically required to be in close proximity to the cleaning target, the dust pushing assembly 48 is typically located below the chassis 50 and the second flexible connector 96 is required to stretch the dust pushing assembly 48 in a vertical direction. In one embodiment, the second driving element 95 is a telescopic driving element, and the telescopic driving element is a driving device with a telescopic stroke, such as an electric cylinder or an air cylinder. The second lifting assembly 90 further includes two second pulleys 97, the two second pulleys 97 are mounted on the second fixing base 92, wherein one second pulley 97 is located in the extending direction of the telescopic end of the second driving element 95; the other end of the second flexible link 96 extends away from the dust pushing assembly 48 via another second pulley 97, and finally the second flexible link 96 can be connected to the chassis 50 to allow the dust pushing assembly 48 to be lifted and lowered by the second driving member 95. The two second pulleys 97 can change the extending direction of the second flexible connecting piece 96, so that the space can be saved, and the arrangement is convenient.

In one embodiment, the roller brush assembly 42, the side brush assembly 44 and the wiper assembly 46 are all connected to the base 30. The dust push assembly 48 is mounted on a chassis 50, and the dust push assembly 48 and the wiper assembly 46 are disconnected. Specifically, the water absorbing rake assembly 46 is mounted on the second bracket 34, and the water absorbing rake assembly 46 swings with the second bracket 34. In addition, round brush subassembly 42, limit brush subassembly 44, absorb water and take off subassembly 46 and can go up and down through first lifting unit 10 in step, dirt pushes away subassembly 48 and goes up and down alone through second lifting unit 90, when second lifting unit 90 drives dirt and pushes away subassembly 48 and contract and be lifted up, absorb water and take off subassembly 46 still can contact with ground, push away subassembly 48 when second lifting unit 90 with dirt, when making dirt push away subassembly 48 and ground contact, still can push up absorb water and take off subassembly 46 to the realization absorbs water and takes off subassembly 46 and dirt and push away the alternate lift of subassembly 48.

It is understood that, according to actual needs, in an embodiment, the first lifting assembly 10 drives the roller brush assembly 42 and the side brush assembly 44 to lift through the base 30, the second lifting assembly 90 may further be connected to the suction assembly 46 and the dust pushing assembly 48, and the second lifting assembly 90 may further drive the suction assembly 46 and the dust pushing assembly 48 to lift together.
