The connector 42 includes a tool portion 422 for tool operation; the limiting portion 424 is a ring of flange formed by the connecting element 42 extending outward, in other embodiments, the limiting portion 424 can be replaced by a gasket sleeved on the connecting element 42, and the effect is the same; and a connecting portion 426, wherein the connecting portion 426 is provided with an external thread. In this embodiment, the elastic member is a spring 44, and in other embodiments, an elastic rubber member may be used as the elastic member. Referring to fig. 8, the sliding groove 21 is formed in a manner that a step 212 is disposed on the mounting plate 20, the sliding groove 21 is disposed at the step 212, a protrusion 214 extending along the length direction of the sliding groove 21 is disposed on the step 212, the protrusion 214 is disposed at two sides of the sliding groove 21, and the top of the protrusion 214 is a curved surface or an arc surface. The connecting portion 426 penetrates through the sliding groove 21 and the spring 44 and is connected with the bottom surface 12, the bottom surface 12 is convexly provided with a plurality of fixing columns 122 matched with the sliding groove 21, connecting holes 128 connected with the connecting piece 42 are formed in the fixing columns 122, the outer diameter of the spring 44 is larger than that of the sliding groove 21, the limiting portion 424 of the connecting piece 42 is pressed on one side of the sliding groove 21, and the spring 44 is pressed on the other side of the sliding groove 21, so that the spring 44 is elastically pressed on the sliding groove 21, and in the sliding process of the connecting piece 42 in the sliding groove 21, the spring 44 and the limiting portion 424 are always in contact with the protrusion 214 without contacting with the step 212, so that the sliding friction force is relatively small, and the. The advantages of this structure are: 1. the connecting piece 42 and the sliding groove 21 form flexible pressing connection, and the connecting piece 42 and the sliding groove 21 can slide relatively; 2. as shown in fig. 11a and 11b, the clamping force can be adjusted, the compression amount of the spring 44 can be adjusted by adjusting the connection between the connecting piece 42 and the fixing post 122, and further the pressing force of the spring 44 on the sliding chute 21 can be adjusted, if the connection fit is too loose, the connecting piece 42 can be screwed to compress the spring 44 to generate larger elastic pressure, and if the sliding is too difficult, the connecting piece 42 can be unscrewed to reduce the pressure of the spring 44 on the sliding chute 21; 3. the mounting plate 20 can float up and down relatively, so that the mop cloth can be more easily adapted to various different ground environments, and the mop cloth can be always attached to the ground, thereby achieving better cleaning effect.

Further, in practical use, it is found that the stability of the spring 44 directly abutting against the slide slot 21 is relatively poor, because the contact surface of the spring 44 and the slide slot 21 generates sliding friction with the slide slot 21 during the reciprocal movement of the connecting member 42 relative to the slide slot 21, and the spring 44 is subjected to transverse shearing force. Normally, the spring 44 can exert a good vertical elastic force, and the spring 44 is twisted when a transverse shearing force is applied, thereby affecting the realization of product performance. Based on this, as shown in fig. 11a and 11b, the connecting member 42 is further sleeved with a gasket 46, the spring 44 abuts against the gasket 46, the gasket 46 directly contacts with the sliding groove 21, the spring 44 is always stably matched with the gasket 46 in the reciprocating process, the spring 44 only receives vertical pressure to the gasket 46, and the gasket 46 and the connecting member 42 share sliding friction force, so that the spring 44 can better exert the product characteristics thereof, and can achieve a more stable use effect.

Referring to fig. 6, 7, 8 and 9, in order to implement the second embodiment of the present invention, the connecting mechanism 40 includes a connecting member 42 and a gasket 46, the connecting member 42 includes a tool portion 422 for tool operation; the limiting portion 424 is a ring of flange formed by the connecting element 42 extending outward, in other embodiments, the limiting portion 424 can be replaced by a gasket sleeved on the connecting element 42, and the effect is the same; and a connecting portion 426, wherein the connecting portion 426 is provided with an external thread. As shown in fig. 6, the connecting portion 426 includes a large diameter section (not shown) having a large outer diameter and a small diameter section (not shown) having a small outer diameter, and the small diameter section is provided with an external thread. The connecting portion 426 penetrates through the sliding groove 21 and is connected with the bottom surface 12, a plurality of fixing posts 122 matched with the sliding groove 21 are arranged on the bottom surface 12 in a protruding mode, connecting holes 128 connected with the connecting piece 42 are formed in the fixing posts 122, and the gasket 46 is sleeved on the small-diameter section and is supported by the fixing posts 128 and the large-diameter section together to form a clamping space with the limiting portion 424. The length of the thick-diameter section determines the size of the clamping space, the height of the clamping space formed by the gasket 46 and the limiting part 424 is larger than the height of the sliding groove 21 to form a small gap, the size of the gap is within 1cm, on one hand, the situation that the sliding groove is tightly clamped due to too tight clamping space and is difficult to slide is avoided, and on the other hand, the situation that the clamping space is too large and generates large shaking is also avoided.

Further, in actual production, it is found that if a large diameter section is provided on the connecting member 42, the connecting member 42 needs to be subjected to a non-calibration. In general, the connecting member 42 is made of a standard screw member, and if the connecting member 42 itself is modified, a non-standard system is required, which increases the manufacturing cost. Referring to fig. 7, to avoid the similar situation, the connecting portion 426 is sleeved with the washer 48, and the spacer 46 is supported by the fixing post 128 and the washer 48 together to form a clamping space with the limiting portion 424. The height of the washer 48 is greater than the height of the runner 21 to form a slight gap within 1cm, so as to avoid the clamping space being too tight to tightly clamp the runner and make it difficult to slide, and avoid the clamping space being too large to cause large shaking.

Referring to fig. 12, which shows a schematic diagram of the reciprocating motion of the eccentric mechanism driving mounting plate 20, in the figure, the rotating block 38 is driven by the motor to rotate clockwise, the driving shaft 381 is arranged eccentrically with respect to the rotating block 38, the driving shaft 381 is inserted into the driving groove 22, the driving shaft 381 is cylindrical, and the diameter of the driving shaft 381 substantially matches the width of the driving groove 22, so that the driving shaft 381 and the driving groove are in close fit, and the driving shaft 381 does not shake in the driving groove 381. During the rotation of the rotating block 38, the driving shaft 381 drives the mounting plate 22 to reciprocate up and down, the reciprocating direction of the driving shaft 381 determines the moving direction of the mounting plate 22 along the extending direction of the slide groove 21, that is, the extending direction of the slide groove 21, if the mounting plate 20 needs to reciprocate along the advancing direction of the cleaning robot RB, the slide groove 21 can be opened along the advancing direction of the cleaning robot RB, and if the mounting plate 20 needs to reciprocate along the vertical direction of the advancing direction of the cleaning robot RB, the slide groove 21 can be opened along the vertical direction of the advancing direction of the cleaning robot RB. In addition, the extending direction of the sliding chute 21 and the extending direction of the driving groove 22 have certain setting requirements, and obviously, the extending direction of the sliding chute 21 and the extending direction of the driving groove 22 cannot be parallel to each other, so that the movable plate 20 cannot move, and the included angle between the sliding chute 21 and the driving groove 22 cannot be too small, otherwise, the mounting plate 20 generates a great sliding friction force in the reciprocating process, thereby consuming the power of the motor unnecessarily. In the above embodiment, the extending direction of the sliding groove 21 is perpendicular to the extending direction of the driving groove 22, i.e. the included angle between the sliding groove 21 and the driving groove 22 is 90 °, and the angle is set to minimize the sliding friction force, so as to achieve the best utilization of the motor power, and the length of the sliding groove 21 can be set to be shorter. In other implementations, the angle between the sliding slot 21 and the driving slot 22 can be set between 60 ° and 90 °.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
