Referring to fig. 1 and 2, the present invention provides a cleaning robot 1000, wherein the cleaning robot 1000 includes a main body (not shown), a mop assembly 20, and a transmission mechanism 30.

The machine body may be mounted with a member for cleaning, a member for driving walking, a member for controlling, and the like. To facilitate replacement of parts for cleaning, the machine body comprises a first part 100 and a second part 200. The first part 100 can be provided with a cleaning component, the second part 200 can be provided with a left wheel assembly, a right wheel assembly, a main circuit board, a fan assembly, a sensor and the like, and the first part 100 and the second part 200 can be detachably connected, so that the cleaning component can be conveniently replaced. In other embodiments, the first portion 100 and the second portion 200 may be integrally formed.

The first portion 100 includes a mounting base 10, the mounting base 10 may be a plate-shaped member, a rod-shaped member, or a member with a regular or irregular shape, and the mounting base 10 may also be a structure formed by connecting two or more members, which is not limited in particular.

The mounting base 10 is connected to the second portion 200, the mopping assembly 20 is used for cleaning a surface to be cleaned, and may be an assembly such as a mop or a mopping roller for mopping a floor, an assembly such as a brush or a wiper strip for sweeping a floor, and an assembly formed by combining the mop and the brush, which are not limited specifically herein.

The mop assembly 20 is floatably attached to the bottom of the mounting base 10, i.e., the bottom of the machine body. It should be noted that there are many embodiments of the floating connection between the mop assembly 20 and the mounting base 10, and several cases will be illustrated below, but the present invention is not limited to the following embodiments.

For example, the mop assembly 20 itself has a flexible portion, and the mounting base 10 is directly connected to the flexible portion of the mop assembly 20; as another example, the mounting base 10 itself has a flexible portion, and the mop assembly 20 is directly connected to the flexible portion of the mounting base 10; for another example, the mop assembly 20 is connected to the mounting base 10 by another elastic member. When so arranged, the mop assembly 20 moves closer to the mounting base 10 through the elastic action, and moves away from the mounting base 10 when being pushed by force, thereby realizing the floating connection between the mounting base 10 and the mop assembly 20.

The transmission mechanism 30 is mounted on the machine body, and the transmission mechanism 30 is configured to be capable of reciprocating and translating, and has a force application state and a force removal state for the mopping assembly 20. It is understood that the transmission mechanism 30 can be mounted on the first portion 100, and the transmission mechanism 30 can also be mounted on the second portion 200, which is not limited herein.

It should be noted that the force applied by the transmission mechanism 30 to the mop assembly 20 can be understood as follows: the transmission mechanism 30 can translate along the mounting base 10 in a direction close to the mop assembly 20 to contact and push the mop assembly 20 to overcome the original elastic force, so that the mop assembly 20 moves in a direction far from the mounting base 10; the force-withdrawing state of the transmission mechanism 30 to the mop assembly 20 can be understood as follows: the transmission mechanism 30 no longer exerts a propping force on the mop assembly 20, so that the mop assembly 20 continues to be acted by the elastic force and returns to the original position, and in the process, the transmission mechanism 30 is propped by the mop assembly 20 contacted with the transmission mechanism to return to the original position.

In addition, the specific structure of the transmission mechanism 30 can be many, such as a long rod, a square block, a cam, a regular or irregular member with other shapes, which only needs to be able to push the mop assembly 20 during the translational motion.

According to the technical scheme, the mopping component 20 is in floating connection with the mounting base 10, so that the mopping component 20 has a movement trend towards the mounting base 10; by configuring the transmission mechanism 30 to be capable of reciprocating and translating, and have a force application state and a force removal state for the mop assembly 20, when the transmission mechanism 30 is in the force application state, the transmission mechanism 30 can push the mop assembly 20 to move in a direction away from the mounting base 10, and when the transmission mechanism 30 is in the force removal state, the mop assembly 20 is influenced by the floating connection with the mounting base 10 to move in a direction close to the mounting base 10. The arrangement is such that the mopping assembly 20 has a floating or lifting effect relative to the mounting base 10, thereby improving the obstacle crossing capability of the cleaning robot 1000.

In some embodiments of the present invention, referring to fig. 1 and 2, the cleaning robot 1000 further includes at least one elastic restoring member 40, each elastic restoring member 40 is connected between the mounting base 10 of the machine body and the mopping assembly 20, and each elastic restoring member 40 is used for driving the mopping assembly 20 to move toward the mounting base 10.

It should be noted that, the connection of the elastic restoring element 40 to the mounting base 10 may be understood that one end of the elastic restoring element 40 is directly fixedly connected to the mounting base 10 by means of embedding, welding, or the like, or that one end of the elastic restoring element 40 abuts against the mounting base 10 by means of abutting, and is not limited specifically herein. Likewise, the resilient return member 40 may be fixedly attached to or abut the mop assembly 20.

It should be noted that the elastic restoring member 40 may be a rubber block, a silicon block, or the like, and the elastic restoring member 40 may also be a spring or a torsion spring, or the like, which is not limited herein.

In order to prevent the dragging and wiping assembly 20 from shifting in the process of moving towards or away from the mounting base 10, further, referring to fig. 1 and 2, at least one guide groove 111 is concavely arranged on the surface of the mounting base 10 facing the dragging and wiping assembly 20, the dragging and wiping assembly 20 is provided with at least one guide rod 211, each guide rod 211 is movably connected with the corresponding guide groove 111, specifically, the guide rod 211 extends into the corresponding guide groove 111 and is movably matched with the guide groove 111, and the dragging and wiping assembly 20 provided with the guide rod 211 can move towards or away from the dragging and wiping assembly 20 along with the axial direction of the guide rod 211. By the arrangement, the mopping assembly 20 can move according to the inherent stroke, and the equipment damage caused by the deviation of the mopping assembly 20 is avoided.

Considering that the mop assembly 20 usually needs to be cleaned with cleaning solution such as clean water, detergent, etc., if the elastic restoring member 40 is exposed, on one hand, the elastic restoring member 40 may be wetted to accelerate aging, and on the other hand, the elastic restoring member 40 may be damaged by an obstacle when being exposed. To avoid the above situation as much as possible, referring to fig. 3 and 4, each elastic restoring member 40 is installed in the corresponding guide groove 111, one end of each elastic restoring member 40 is connected to the groove bottom of the corresponding guide groove 111, and the other end of each elastic restoring member 40 is connected to the corresponding guide rod 211. The elastic deformation of the elastic resetting piece 40 in the guide groove 111 is limited by the inner space of the guide groove 111, that is, the elastic resetting piece 40 does not break through the inner space of the guide groove 111 in the process of elastic deformation, so that the problem that the elastic resetting piece 40 is not stressed uniformly and elastically deformed in the circumferential direction to fall off or be damaged is avoided.

It should be noted that the elastic restoring member 40 is under the action of the self-weight of the mop assembly 20, and the elastic restoring member 40 gives the mop assembly 20 an elastic pulling force close to the mounting base 10, so that the mop assembly 20 has a tendency of moving toward the mounting base 10, and in view of this, the mop assembly 20 and the mounting base 10 are both connected to the elastic restoring member 40 by fastening, embedding, welding, or other fixed connection.

To facilitate removal and replacement of the mop assembly 20, the resilient return member 40 may be removably coupled to the mounting base 10, and the resilient return member 40 may also be removably coupled to the mop assembly 20. The following examples illustrate the detachable connection of elastic restoring member 40 to mounting base 10:

for example, the bottom of the guiding groove 111 is provided with a clamping structure, and one end of the elastic restoring member 40 away from the mopping assembly 20 is clamped and fixed by the clamping structure. Wherein, this clamping structure can be by two sliders that receive pneumatic control and constitute, and two sliders can be by pneumatic control and be close to each other with the reset piece 40 of centre gripping elasticity, perhaps keep away from each other in order to release the reset piece 40 of elasticity, and this clamping structure is common in all kinds of machining anchor clamps and processing lathe, and no longer repeated here.

For another example, referring to fig. 3 and 4, the mounting base 10 includes a base body 11 and at least one mounting block 12, each mounting block 12 is detachably mounted on a side of the base body 11 facing the mop assembly 20, and a guide groove 111 is concavely formed on a surface of each mounting block 12 facing the mop assembly 20. When it is desired to remove the mop assembly 20, the mounting block 12 can be removed directly from the base body 11 so that the mop assembly 20 and the mounting block 12 are detached from the mounting base 10.

In another embodiment of the present invention, referring to fig. 5 and 6, the mounting base 10 is provided with at least one offset through hole (not shown) along a direction approaching to or departing from the mop assembly 20; the mop assembly 20 is provided with at least one connecting arm 212 extending towards the mounting base 10 of the machine body, each connecting arm 212 being arranged through a corresponding abdicating through-hole. So configured, the connecting arm 212 is also limited to the offset through hole during the movement of the mop assembly 20, thereby preventing the mop assembly 20 from shifting toward or away from the mounting base 10.

With continued reference to fig. 5 and 6, one end of each elastic restoring member 40 abuts against a side of the mounting base 10 of the machine body facing away from the mop assembly 20, and the other end of each elastic restoring member 40 abuts against a corresponding end of the connecting arm 212 away from the mop assembly 20. This allows the connecting arm 212 to be elastically supported by the elastic restoring member 40, so that the mop assembly 20 moves toward the mounting base 10.

In addition, so set up and to let elasticity reset piece 40 and drag and wipe subassembly 20 and carry out the separation through mounting base 10, on the one hand avoid dragging the cleaning solution sputter on the subassembly 20 of wiping or wet in elasticity reset piece 40 on, on the other hand has also eliminated elasticity reset piece 40 and the impaired risk of external barrier collision.

Further, referring to fig. 5 and fig. 6, the connecting arm 212 includes a connecting section 212a and a limiting section 212b, one end of the connecting section 212a is connected to the mop assembly 20, the other end of the connecting section 212a passes through the corresponding abdicating through hole, the limiting section 212b laterally protrudes out of one end of the connecting section 212a away from the mop assembly 20, the elastic reset member 40 is a sleeve spring, the sleeve spring is sleeved and matched with the connecting arm 212, one end of the sleeve spring is abutted to the mounting base 10, and the other end of the sleeve spring is abutted to the limiting section 212 b. Obviously, the wrap spring is not dropped out by the influence of the stopper section 212b, and the stability of the elastic restoring member 40 is ensured.

It should be noted that the limiting section 212b may be formed by protruding one side of the end of the connecting section 212a away from the mop assembly 20, the limiting section 212b may also be formed by protruding multiple sides of the end of the connecting section 212a away from the mop assembly 20, and the limiting section 212b may also be formed by integrally protruding the peripheral side of the end of the connecting section 212a away from the mop assembly 20, which is not limited in this respect.

To facilitate resilient attachment of the mop assembly 20 to the mounting base 10, in some embodiments of the utility model, the mop assembly 20 includes a mop support 21 and a mop 22 mounted to the mop support 21.

The mop holder 21 is attached to a side of the mounting base 10, and the mop 22 is attached to a side of the mop holder 21 opposite to the mounting base 10. The mop support 21 is provided with at least one resilient coupling (not shown), and the mop support 21 is connected to the mounting base 10 of the machine body by at least one resilient coupling for moving the mop assembly in a direction close to the machine body.

It should be noted that the elastic connection portion may be configured as a metal elastic sheet, and the elastic connection portion may also be configured as a rubber strip or a silicone strip, which is not specifically limited herein.

In some embodiments of the present invention, referring to fig. 1, the transmission mechanism 30 further includes a driving assembly 50 and a transmission member 31 in transmission connection with the driving assembly 50, the driving assembly 50 is mounted on the machine body, and the driving assembly 50 is used for driving the transmission member 31 to move in a translational manner along the mounting base 10 in a direction (a direction parallel to the height of the machine body) toward or away from the mopping assembly 20. The transmission member 31 may be movably or fixedly connected to the mop assembly 20, or the transmission member 31 may be free of a connection structure with the mop assembly 20. Several embodiments of the driving assembly 50 and the transmission member 31 are described below, but the driving assembly 50 and the transmission member 31 are not limited to the following embodiments.

For example, the driving assembly 50 includes a rotating motor, and the transmission member 31 includes a transmission shaft connected to an output shaft of the rotating motor, the transmission shaft being provided with a rack along an axial direction thereof, the rack being engaged with the gear. When the rotating motor is powered on and started, the gear can be driven to rotate, and then the transmission shaft provided with the rack is driven to abut against the mopping assembly 20 to move towards the direction far away from the machine main body; when the rotating motor is turned off in case of power failure, the output shaft of the rotating motor loses power and can be driven by the gear to rotate, and the transmission shaft is pushed back to the original position by the dragging and wiping assembly 20.

For another example, referring to fig. 1 and fig. 3, the driving assembly 50 includes an air cylinder 51 and an air pump 52 mounted on the mounting base 10, the air cylinder 51 is in pneumatic communication with the air pump 52; the transmission member 31 includes a piston portion and a rod portion connected to the piston portion, the piston portion is located in the cylinder 51 and is in sliding fit with an inner wall of the cylinder 51, and one end of the rod portion, which is far away from the piston portion, abuts against a surface of the mop assembly 20 facing the machine main body (the mounting base 10). When the air pump 52 works to charge the air cylinder 51, the piston part is extruded and translated, and the push rod part translates along with the piston part, so that the mopping assembly 20 is resisted to move in a direction away from the mounting base 10; when the air pump 52 is deactivated and no longer charges the air cylinder 51, the push rod portion and the piston portion are pushed back into place by the mop assembly 20.

Obviously, the air cylinder 51 and the air pump 52 have the advantages of simple transmission structure, simple control mode and the like, and the devices such as the air cylinder 51 and the air pump 52 adopt the sealing transmission, so that the device is not easily influenced by the outside, and further has the advantages of long service life, stable work and the like.

It should be noted that the surface of the pushing rod portion contacting the mop assembly 20 may be made of a material that is easily elastically deformed, such as silicone rubber or rubber, or the surface of the pushing rod portion contacting the mop assembly 20 may be connected with a buffer member, such as a rubber block or a spring, so as to prevent the pushing rod portion from being hard collided with the mop assembly 20, which may damage the mop assembly 20.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
