Of course, the length direction and the width direction of the charging interface 10 are also relative, and when the charging interface 10 is square, it can be described by a horizontal longitudinal direction and a horizontal transverse direction. The above directions are defined for convenience of description and are not specific to a certain uniquely identified, absolute direction, and thus the first direction and the second direction are named for convenience of description only.

As shown in fig. 2 to 6, in actual use, the number of the charging interfaces 10 is two, each group of charging interfaces 10 has a corresponding electrode tab 12, and it can be determined that the electrode tab 12 corresponding to one group of charging interfaces 10 is a positive electrode, and the electrode tab 12 corresponding to the other group of charging interfaces 10 is a negative electrode. The corresponding plug connector also has two charging pole pieces which are respectively in surface contact fit with the two electrode pieces 12 so as to realize the pile alignment of the plug connector relative to the charging interface 10. When the number of the charging interfaces 10 is two, two electrode brackets 11 may be provided, that is, each group of charging interfaces 10 corresponds to one electrode bracket 11, which is equivalent to that the two groups of charging interfaces 10 are combined into a complete whole by splicing the two electrode brackets 11. Or, it may also be that one electrode holder 11 has two installation cavities that communicate, be first installation cavity and second installation cavity respectively, and be provided with two relative and interval arrangement's boss between two installation cavities, one of them electrode slice 12 can with the first face butt of this boss, another electrode slice 12 can with the second face butt of this boss, first face and second face are relative and the interval sets up. At this time, the two electrode plates 12 can share the supporting column 13, the supporting column 13 is divided into two parts by the boss, the two parts are respectively a first cylinder body located in the first installation cavity and a second cylinder body located in the second installation cavity, and the first cylinder body and the second cylinder body are respectively sleeved with the first elastic piece 14 correspondingly so as to apply acting force of reverse movement to the two electrode plates 12.

In order to facilitate the stable matching of the plug connector and the charging interface 10 to perform the charging operation on the cleaning mechanism 30, as shown in fig. 1 to 8, an embodiment of the present invention further provides a charging structure, which includes two sets of charging interfaces 10 and a plug assembly 20; the two groups of charging interfaces 10 are arranged along the second direction; the plug assembly 20 has a first charging pole piece 211 and a second charging pole piece 212, and the first charging pole piece 211 and the second charging pole piece 212 are arranged oppositely and at intervals along a second direction; the first charging pole piece 211 and the second charging pole piece 212 are respectively connected with the two groups of charging interfaces 10. As mentioned above, the two sets of charging interfaces 10 correspond to the two electrode pads 12, i.e. the first electrode pad 1201 and the second electrode pad 1202, respectively, the first electrode pad 1201 is in surface contact with the first charging pad 211, and the second electrode pad 1202 is in surface contact with the second charging pad 212.

In actual use, taking the plug assembly 20 inserted in a horizontal direction as an example, as the plug assembly 20 is inserted relative to the cleaning mechanism 30, the first charging pole piece 211 exerts a force on the first electrode piece 1201 vertically upward along the supporting column 13, so as to cause the first electrode piece 1201 to move vertically upward along the supporting column 13. The second charging pole piece 212 exerts a force on the second electrode sheet 1202 vertically downward along the support column 13, causing the second electrode sheet 1202 to move vertically downward along the support column 13. That is, the second electrode sheet 1202 and the first electrode sheet 1201 are moved in opposite directions away from each other so that the first charging pole piece 211 and the second charging pole piece 212 can be inserted between the first electrode sheet 1201 and the second electrode sheet 1202. When the plug assembly 20 is inserted into the cleaning mechanism 30 to a certain extent, the first charging pole piece 211 no longer applies an acting force to the first electrode plate 1201, the second charging pole piece 212 no longer applies an acting force to the second electrode plate 1202, and the first electrode plate 1201 and the second electrode plate 1202 can move in opposite directions under the elastic action of the corresponding first elastic members 14, so as to be in press fit with the corresponding first charging pole piece 211 and the corresponding second charging pole piece 212, and timely and sufficient contact is achieved.

Specifically, in the two sets of charging interfaces 10, the second connecting piece 122 of the first electrode plate 1201 extends obliquely upward along the vertical direction, and the second connecting piece 122 of the second electrode plate 1202 extends obliquely downward along the vertical direction, that is, extends back to back. At this time, the first charging pole piece 211 corresponding to the first electrode sheet 1201 has a first inclined plane adapted to the first electrode sheet 1201, the second charging pole piece 212 corresponding to the second electrode sheet 1202 has a second inclined plane adapted to the second electrode sheet 1202, and by the arrangement of the first inclined plane and the second inclined plane, the surface contact between the first electrode sheet 1201 and the first charging pole piece 211 and the surface contact between the second electrode sheet 1202 and the second charging pole piece 212 are realized. The first charging pole piece 211 and the second charging pole piece 212 are both disposed on the plug connector 21, and the plug connector 21 is movably connected to the plug support 22.

The plug 21 is connected to the side of the connecting frame 221 facing away from the foot block 222 via the cross-coupling 23. When the connecting frame 221 approaches the cleaning mechanism 30 relative to the tailstock 222, the plug 21 moves synchronously with the connecting frame 221.

Specifically, the cover 24 is connected to the tail block 222 to cover the connecting frame 221 and the plug 21. When the plug assembly 20 is not connected to the charging interface 10, the plug connector 21 and the plug bracket 22 are accommodated in the cover 24 to protect the plug connector 21. When the plug assembly 20 needs to be mated with the charging interface 10, along with the insertion of the plug assembly 20 into the charging interface 10, one end of the cover 24 away from the tail seat 222 abuts against the outer side of the cleaning mechanism 30, so that an acting force opposite to the insertion direction of the plug assembly 20 is applied to the cover 24, the cover 24 can be pushed to move along one side opposite to the insertion direction, the plug 21 can extend out of the cover 24, and the plug is conveniently mated with the electrode plate 12 in the charging interface 10.

That is, when the plug 21 is extended relative to the housing 24, the second elastic member 26 is subjected to a force applied by the housing 24 in the opposite direction to the insertion direction, so that the second elastic member 26 is deformed. After the charging operation is completed, the plug assembly 20 is pulled out relative to the charging interface 10, and at this time, the cover 24 can move along the insertion direction under the action of the elastic potential energy of the second elastic element 26, so that the cover 24 can be covered on the plug 21, i.e., the plug 21 is accommodated in the cover 24 to return to the initial state.
