In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and so forth. In other instances, well-known methods, devices, implementations, or operations have not been shown or described in detail to avoid obscuring aspects of the disclosure.

The embodiment of the disclosure provides a cleaning robot, which can be used for sweeping and mopping the floor to clean the environmental sanitation. The cleaning robot may include a main frame structure and a water tank dust box. The main machine structure is mainly used for providing driving force to realize the walking function of the cleaning robot, and is also used for realizing the cleaning function. The water tank dust box can be arranged on the main machine structure and is used for providing cleaning liquid such as water and the like and collecting objects such as dust, impurities and the like in the process of realizing the cleaning function.

The host structure of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the host structure may include a bottom case 10 and a cleaning assembly 11. The bottom case 10 may include a bottom surface 101, and the bottom surface 101 may be a plane, but is not limited thereto. The cleaning assembly 11 is disposed on the bottom case 10, and at least a portion of the cleaning assembly 11 protrudes downward relative to the bottom surface 101 of the bottom case 10 to contact with a surface to be cleaned (e.g., a floor surface b as shown in fig. 4 and 6), so as to perform a cleaning function.

As shown in fig. 1 and 2, the cleaning assembly 11 may include a roll brush 110 provided on the bottom case 10. Specifically, a portion (e.g., a roller portion) of the roller brush 110 may be disposed in the bottom case 10, and another portion (e.g., a brush or sponge brush portion) may extend out of the bottom case 10 and protrude downward relative to the bottom surface 101 of the bottom case 10 to contact with the ground b for cleaning.

Wherein, during the rolling process of the rolling brush 110, the brush or sponge brush part thereof rotates to the inside of the bottom case 10 to cooperate with a water tank dust box (not shown), that is: receives cleaning liquid from the water box to achieve a wet state, and then the wet portion is rotated to the outside of the bottom case 10 for mopping the floor b along with the rolling process.

After the cleaning surface is mopped by the rolling brush 110, some waste water is usually remained on the ground surface b, and some waste is remained without being completely cleaned, so, in order to improve the cleaning effect of the cleaning robot, as shown in fig. 1 and 2, the cleaning assembly 11 of the embodiment of the present disclosure may further include a scraping bar 111, and this scraping bar 111 may be located at the rear end of the rolling brush 110 in the advancing direction Y of the cleaning robot, for scraping away the waste water and the waste remained after the rolling brush 110 is operated.

Part of the scraping bar 111 may be disposed in the bottom case 10 and connected to the bottom case 10, so that the scraping bar 111 is fixed on the bottom case 10. Another portion of the scraping bar 111 may protrude out of the bottom case 10 and protrude downward with respect to the bottom surface 101 to be able to contact with the ground b for scraping off waste water and garbage remaining after the operation of the drum brush 110.

In the embodiment of the present disclosure, the scraping strip 111 may have a certain elasticity, so that when the rolling brush 110 waits for the cleaning surface to clean the ground b, the scraping strip 111 and the ground b can be ensured to be in interference fit, thereby ensuring the scraping force of the scraping strip 111, and improving the cleaning effect.

For example, as shown in fig. 5a and 5b, the wiper strip 111 according to the embodiment of the disclosure may include a connecting portion 1110, a bending portion 1112, and a deformable portion 1111. The connecting portion 1110 may be connected to the bottom case 10, and specifically, the connecting portion 1110 may be located inside the bottom case 10. The deformable portion 1111 may be located at the lowermost end of the wiper strip 111, and the bottom surface of the deformable portion 1111 may contact the surface to be cleaned for wiping away waste water and garbage remaining after the operation of the roll brush 110. One end of the bent portion 1112 is connected to the connecting portion 1110, and the other end is connected to the tip of the deformable portion 1111, and the bent portion 1112 is disposed to be inclined with respect to both the connecting portion 1110 and the deformable portion 1111.

In the embodiment of the present disclosure, the deformable portion 1111 may have a certain flexibility, and may be easily deformed by a force applied thereto, so as to ensure interference contact with the ground b when cleaning the ground b, thereby ensuring a cleaning effect, and may be deformed by a thrust from the step when crossing an obstacle, thereby smoothly crossing the obstacle. While connecting portion 1110 and bent portion 1112 may have a certain rigidity, namely: deformation is not easy to occur so as to ensure the structural strength of the scraping strip 111 and the connection stability with the bottom shell.

As shown in fig. 1 and 2, the entire scraping strip 111 may be a long strip, and the length direction X may be parallel to the axial direction of the roller brush 110. As shown in fig. 2, both ends of the scraping bar 111 in the length direction X may be aligned with both ends of the rolling brush 110 in the axial direction thereof, but not limited thereto, as shown in fig. 1, both ends of the scraping bar 111 in the length direction X may also be beyond both ends of the rolling brush 110 in the axial direction thereof and bent toward the rolling brush 110, so as to better scrape away waste water and garbage remaining after the rolling brush 110 is operated, and improve the cleaning effect.

It should be understood that the axial direction of the roll brush 110 and the length direction X of the wiper strip 111 mentioned herein may intersect with the advancing direction Y of the cleaning robot; further, the axial direction of the roller brush 110 and the length direction X of the scraping strip 111 are perpendicular to the advancing direction Y of the cleaning robot, so that the size of the roller brush 110 and the scraping strip 111 can be reduced properly while the cleaning effect is ensured in the advancing process, the cost is reduced, and the space is saved.

In addition, it should be noted that, when the cleaning robot is actually used, the cleaning robot not only travels on the horizontal ground b for cleaning, but also needs to go over steps, doorsills, and other structures to some extent, or go over the bumpy ground b to achieve cleaning.

However, based on the aforementioned structure of the main body, when the cleaning robot moves forward, the front end of the cleaning robot meets the step a, as shown in fig. 4, if the support rib 12 mentioned later is not provided, as shown in fig. 5a, when the height h5 of the step a is greater than the height h4 of the deformable portion 1111 of the wiper strip 111, the top end of the step a directly abuts against the bent portion 1112 of the wiper strip 111 before the obstacle is overcome, but since the bent portion 1112 is rigid and is not easily deformed by a force, the cleaning robot is difficult to overcome the step a.

Further, as shown in fig. 5b, when the height h5 of the step a is less than or equal to the height h4 of the deformable portion 1111 of the wiper strip 111, the step a will be directly abutted against the deformable portion 1111 of the wiper strip 111 before the obstacle crossing, and at this time, the entire side surface of the step a will be in contact with the deformable portion 1111, and during the obstacle crossing, the top end of the step a will give a large horizontal pushing force F to the deformable portion 1111 to force the deformable portion 1111 of the wiper strip 111 to deform backward, and this horizontal pushing force F is a force opposite to the driving force of the cleaning robot during the forward movement, so that most of the driving force will be cancelled out, and the obstacle crossing ability of the cleaning robot is greatly reduced.

Aiming at the problem, in the design process, the obstacle crossing capability of the cleaning robot is improved to a certain extent.

In detail, the host structure of the embodiment of the present disclosure may further include a supporting member, and the supporting member may be disposed on the bottom case 10. Alternatively, the support member as a whole may be provided to protrude downward with respect to the bottom surface 101 of the bottom case 10. For example, the supporting member may be integrally formed with the bottom case 10 to ensure the stability of the connection between the supporting member and the bottom case 10 and prolong the service life of the product, but is not limited thereto, and the supporting member may also be connected with the bottom case 10 by a locking member such as a screw or by welding, as the case may be.

As shown in fig. 1 and 2, the supporting member may include supporting ribs 12 disposed on opposite sides of the cleaning assembly 11 in the length direction X, but is not limited thereto, the number of the supporting ribs 12 is not limited to two, and may also be one, and when the supporting rib 12 is one, it may be disposed at the front end of the cleaning assembly 11; alternatively, four, six, etc. support ribs 12 can also be provided, namely: the cleaning assembly 11 is flanked in the length direction X by two or more support ribs 12, etc., as the case may be.

As shown in fig. 6 and 7a to 7b, the distance between the bottom surface 101 of the bottom case 10 and the horizontal floor surface b during the cleaning process of the cleaning robot on the horizontal floor surface b may be a first distance h1, the distance between the lowest point of the bottom surface of the supporting rib 12 (i.e. the point closest to the bottom surface) and the bottom surface 101 of the bottom case 10 may be a second distance h2, and the second distance h2 is smaller than the first distance h1 of fig. 5a, that is, the supporting rib 12 does not contact the horizontal floor surface b during the cleaning process of the cleaning robot on the horizontal floor surface b, that is: the condition of scraping with horizontal ground b can not appear in support rib 12 to reduce the frictional force of cleaning machines people when horizontal ground b cleans, when guaranteeing that cleaning machines people is in horizontal ground b stable driving, still can reduce the drive energy consumption.

As shown in fig. 1 to 3, 6, 7a and 7b, the supporting rib 12 may include a first guiding portion 120, and at least a portion of the first guiding portion 120 is located at a front end of the scraper bar 111 in the advancing direction Y, that is, when the front end of the cleaning robot encounters an obstacle such as a step during the traveling process, the step a may contact the first guiding portion 120 first. The distance between the lowest point of the first guide part 120 at the front end of the scraping bar 111 and the lowest point of the deformable part is a third distance h3, the third distance h3 is less than or equal to the height h4 of the deformable part, that is, the lowest point of the first guide part 120 at the front end of the scraping bar 111 can be flush with the vertex of the deformable part (i.e. the point close to the bending part 1112) or lower than the vertex of the deformable part and higher than the lowest point of the deformable part, so that the situation that the cleaning robot is difficult to pass over the step a as obstacles such as steps are pushed to the bending part 1112 in the obstacle crossing process can be avoided.

Specifically, the interval between the bottom surface of the first guide 120 and the bottom surface 101 of the bottom case 10 in the support rib 12 gradually increases in a direction along the front end of the first guide 120 to the rear end thereof, that is, the bottom surface of the first guide 120 may be an inclined surface, for example: the cambered surface or the inclined plane is designed in such a way that when the cleaning robot encounters obstacles such as steps, the inclined bottom surface of the first guide part 120 can be utilized, so that the front end of the cleaning robot is slowly lifted, and the cleaning robot can stably cross the obstacles.

However, since the bottom surface of the first guide part 120 is an inclined surface, in the process of slowly lifting the front end of the cleaning robot by using the inclined bottom surface of the first guide part 120, as shown in fig. 7a, the bottom surface of the first guide part 120 can resolve the thrust F applied to the front step, that is: the horizontal force Fa and the vertical force Fb are resolved, so that the horizontal force applied to the cleaning robot in the obstacle crossing process is reduced to Fa, and the loss of the cleaning robot in slow lifting can be reduced.

In the obstacle crossing process, as shown in fig. 5a and 7b, when the height h5 of the step a is greater than the height h4 of the deformable portion 1111 of the scraping bar 111, the front end of the cleaning robot is lifted by using the inclined bottom surface of the first guide portion 120 of the support rib 12, and the scraping bar 111 is lifted at the same time, so that the situation that the top end of the step a is propped against the bent portion 1112 of the scraping bar 111 in the obstacle crossing process can be avoided, and the situation that the cleaning robot is difficult to cross the step a due to the fact that the bent portion 1112 is rigid and is difficult to deform under force can be avoided; that is, by using the inclined bottom surface of the first guide portion 120 of the support rib 12, the wiper strip 111 is raised until only the deformable portion 1111 thereof comes into contact with the tip of the step a, and the deformable portion 1111 is deformed rearward by the force, so that smooth obstacle crossing can be achieved.

In addition, in the obstacle crossing process, as shown in fig. 5b and 7b, when the height h5 of the step a is less than or equal to the height h4 of the deformable portion 1111 of the scraper bar 111, by using the inclined bottom surface of the first guide portion 120 of the support rib 12, the scraper bar 111 can be raised at the same time of raising the front end of the cleaning robot, so that the contact area between the step a and the deformable portion 1111 can be reduced, and the deformable portion 1111 can also decompose the acting force F from the step, as shown in fig. 7b, the horizontal force Fa and the vertical force Fb are decomposed, so that the horizontal force applied to the cleaning robot in the obstacle crossing process is reduced to Fa, and compared with the scheme without the support rib 12, the loss of the cleaning robot in the obstacle crossing process can be reduced, so that the obstacle crossing capability of the cleaning robot can be improved.

In conclusion, the cleaning robot disclosed by the invention can cross the steps higher than the height of the deformable portion 1111 in the scraping strip 111 by arranging the supporting ribs 12, the obstacle crossing capability of the cleaning robot is improved, so that the cleaning robot can be suitable for more cleaning environments, and in addition, the loss of the cleaning robot in the obstacle crossing process can be reduced for crossing the steps lower than or equal to the height of the deformable portion 1111 in the scraping strip 111, and the energy-saving effect is realized.

As shown in fig. 6, 7a and 7b, the ratio of the third distance h3 (i.e. the distance between the lowest point of the first guide part 120 at the front end of the wiper strip 111 and the lowest point of the deformable part 1111) to the height h4 of the deformable part 1111 is less than 1, so that the deformable part 1111 can be deformed to complete obstacle crossing by a small force, and the loss of the cleaning robot in the obstacle crossing process can be reduced.

Further, the ratio of the distance h3 between the lowest point of the first guide part 120 located at the front end of the scraper bar 111 and the lowest point of the deformable part 1111 to the height h4 of the deformable part 1111 is less than or equal to 0.5, and the force applied when the deformable part 1111 deforms and passes the obstacle is further reduced, so that the loss of the cleaning robot in the obstacle passing process is further reduced.

For example, as shown in fig. 4, 5a and 5b, the height h4 of the deformable portion 1111 of the wiper strip 111 may range from 1mm to 3mm, for example: the height h4 of the deformable portion 1111 in the wiper strip 111 may be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc.; and the distance h3 between the lowest point of the first guide part 120 at the front end of the scraping bar 111 and the lowest point of the deformable part 1111 is greater than 0 and less than or equal to 1.5mm, such as: 0.5mm, 1mm, 1.5mm, etc.

As shown in fig. 6, 7a and 7b, a portion (i.e., may be defined as an obstacle crossing section) of the first guide part 120 may be located at a front end of the wiper strip 111 in the advancing direction Y and opposite to opposite sides of the roller brush 110 in the length direction X, it should be understood that the obstacle crossing section is located at the front end of the wiper strip 111 in the advancing direction Y, and a distance between a lowest point of a bottom surface of the obstacle crossing section and a lowest point of the deformable part 1111 is less than or equal to a height of the deformable part 1111; another portion (i.e., may be defined as a transition section) of the first guide portion 120 may be located at the rear end of the scraping bar 111 in the advancing direction Y, and the lowest point of the bottom surface of the transition section is the lowest point of the bottom surface of the first guide portion 120; since the distance between the bottom surface of the first guide portion 120 of the support rib 12 and the bottom surface 101 of the bottom case 10 gradually increases in the direction from the front end to the rear end of the first guide portion 120, it can be seen that the lowest point of the bottom surface of the first guide portion 120 may be located at the rear end of the wiper strip 111 in the advancing direction Y, and this design can ensure that the wiper strip 111 keeps contact with the floor b before the obstacle is cleared, so that the remaining area of the floor b is minimized, thereby ensuring the cleaning effect of the cleaning robot.

However, the entire first guide 120 may be located at the front end of the wiper strip 111 in the forward direction Y, that is, the lowest point of the bottom surface of the first guide 120 may be located at the front end of the wiper strip 111 in the forward direction, and the distance h3 between the lowest point of the bottom surface of the first guide 120 and the lowest point of the deformable portion 1111 may be equal to or less than the height h4 of the deformable portion 1111.

Alternatively, as shown in fig. 1 to 3, 6, 7a and 7b, the support rib 12 may further include a second guide portion 121, the second guide portion 121 is located at the rear end of the first guide portion 120, the front end of the second guide portion 121 is in contact with the rear end of the first guide portion 120, and the distance between the bottom surface of the second guide portion 121 and the bottom surface 101 of the bottom case 10 is gradually reduced in the direction from the front end of the second guide portion 121 to the rear end thereof, that is, the bottom surface of the second guide portion 121 may be an inclined surface, for example: a cambered surface or an inclined plane, which enables the cleaning robot to smoothly land after the obstacle crossing.

The lowest point of the bottom surface of the second guiding portion 121 may coincide with the lowest point of the bottom surface of the first guiding portion 120, that is, in the working process of the cleaning robot, after the cleaning robot passes through the first guiding portion 120, the cleaning robot smoothly lands directly through the second guiding portion 121, so that the design ensures the overall obstacle crossing capability of the support rib 12, and simultaneously, the stroke of the scraping bar 111 separating from the ground b during driving is shorter.

It should be understood that the lowest point of the bottom surface of the second guide part 121 and the lowest point of the bottom surface of the first guide part 120 can be understood as the lowest point of the bottom surface of the entire support rib 12.

Further, the front end of the bottom surface of the first guide part 120 contacts the bottom surface 101 of the bottom case 10 to further ensure obstacle surmounting capability, and the rear end of the bottom surface of the second guide part 121 contacts the bottom surface 101 of the bottom case 10 to further ensure landing smoothness.

For example, as shown in fig. 3, 7a and 7b, the bottom surface of the first guide part 120 and the bottom surface of the second guide part 121 may be both arc surfaces to ensure the structural strength of the support rib 12; but not limited thereto, the bottom surface of one of the first guide portion 120 and the second guide portion 121 may be an arc surface, and the bottom surface of the other may be an inclined plane; or both the bottom surface of the first guide part 120 and the bottom surface of the second guide part 121 are inclined planes.

When the bottom surface of the first guide part 120 and the bottom surface of the second guide part 121 are both arc surfaces, the curvature of the bottom surface of the first guide part 120 may be greater than that of the bottom surface of the second guide part 121; when the bottom surfaces of the first guide part 120 and the second guide part 121 are both inclined planes, an included angle between the bottom surface of the first guide part 120 and the bottom surface 101 of the bottom case 10 is smaller than an included angle between the bottom surface of the second guide part 121 and the bottom surface 101 of the bottom case 10; when the bottom surface of the first guide portion 120 is an arc surface and the bottom surface of the second guide portion 121 is an inclined plane, an included angle between a cutting surface corresponding to the bottom surface of the first guide portion 120 and the bottom surface 101 of the bottom case 10 is smaller than an included angle between the bottom surface of the second guide portion 121 and the bottom surface 101 of the bottom case 10; when the bottom surface of the first guide portion 120 is an inclined plane and the bottom surface of the second guide portion 121 is an arc surface, an included angle between the bottom surface of the first guide portion 120 and the bottom surface 101 of the bottom case 10 is smaller than an included angle between a cutting surface corresponding to the bottom surface of the second guide portion 121 and the bottom surface 101 of the bottom case 10.

With the above arrangement, the length of the second guide portion 121 in the advancing direction Y can be made smaller than the length of the first guide portion 120 in the advancing direction Y, so that the stroke of the wiper strip 111 separating from the ground b during traveling can be made shorter while ensuring smooth surmounting.

Illustratively, as shown in fig. 1 and 2, the main machine structure may further include a universal wheel 13 and a plurality of driving wheels 14. The driving wheel 14 is arranged on the bottom shell 10 and is positioned at the rear end of the scraping strip 111 in the advancing direction Y of the cleaning robot; as shown in fig. 1 and 2, two driving wheels 14 may be provided and arranged at intervals in the length direction X of the wiper strip 111; the driving wheel 14 is used for driving the main machine structure to move; universal wheel 13 can locate on drain pan 10 to be located the rear end of drive wheel 14 on advancing direction Y, specifically as shown in the figure, the middle zone of host computer structure rear end can be located to universal wheel 13, and this universal wheel 13 mainly used drives the host computer structure and rotates, so that cleaning machines people can carry out 360 rotations, realizes diversified cleanness.

It should be understood that the distance between the lowest point of the bottom surface of the driving wheel 14 and the universal wheel 13 and the bottom surface 101 of the bottom case 10 may be greater than the distance between the lowest point of the bottom surface of the supporting rib 12 and the bottom surface 101 of the bottom case 10, so that when the cleaning robot cleans the floor b, it is ensured that the supporting rib 12 does not contact the floor b when the driving wheel 14 and the universal wheel 13 contact the floor b, so as to reduce the friction force when the floor b moves.
