Specifically, the mounting seat 10 includes a seat body 11 and a bottom plate 12, the accommodating cavity 101 is disposed in the seat body 11, the accommodating cavity 101 penetrates through the seat body 11, the bottom plate 12 is mounted in the seat body 11, and covers a cavity opening at one end of the accommodating cavity 101, and a cavity opening at the other end of the accommodating cavity 101 is exposed on the seat body 11.

The limiting column 21, the movable plate 22 and the elastic element 23 of the connecting assembly 20 are all disposed in the accommodating cavity 101. Specifically, one end of the limiting column 21 is fixed to the bottom plate 12, the other end of the limiting column 21 extends toward the opening of the other end of the accommodating cavity 101, the connecting hole 2201 of the movable plate 22 is sleeved at the other end of the limiting column 21, one end of the movable plate 22 extends out of the accommodating cavity 101, the movable plate 22 can move in the accommodating cavity 101 relative to the seat body 11, one end of the elastic element 23 abuts against the bottom plate 12, and the other end of the elastic element 23 abuts against the movable plate 22 and provides an elastic acting force for the movable plate 22.

It will be appreciated that when there is a large left-right misalignment between the charging terminals and the electrodes 30, the movable plate 22 needs to move left and right, i.e. along the y-axis, or rotate a large amount around the z-axis to align the charging terminals. Therefore, in some embodiments, as shown in fig. 4, the connection hole 2201 is waist-shaped, and the width of the connection hole 2201 is greater than the height of the connection hole 2201, so as to allow the movable plate 22 to move left and right in the connection hole 2201 or rotate around the z-axis by a greater extent, so that the charging stand 100 can adapt to a cleaning robot with greater left and right deviation, and the alignment capability of the charging stand 100 is improved. The width direction of the connection hole 2201 is parallel to the y-axis, and the height direction of the connection hole 2201 is parallel to the z-axis.

Generally, when the cleaning robot and the charging stand 100 are aligned, with reference to the ground, the height of the charging terminal and the height of the electrode 30 are substantially equal, and the movable plate 22 does not need to move a large distance on the z-axis, so as to refer to fig. 6, fig. 6 is a partial enlarged view of the portion a of the charging stand 100 shown in fig. 5, in some embodiments, the height of the connection hole 2201 is gradually reduced along the direction in which the other end of the limiting post 21 points to one end of the limiting post 21, so that while the movement distance of the movable plate 22 along the z-axis direction is limited, the rotation angle of the movable plate 22 around the y-axis can be prevented from being greatly limited, and the alignment work of the cleaning robot and the charging stand 100 is facilitated. Wherein, the height direction of the connection hole 2201 is parallel to the z-axis.
