[0002] Common surface cleaning equipment includes: floor cleaning equipment (such as floor scrubbers, smart sweeping robots, vacuum cleaners), tabletop cleaning equipment and wall cleaning equipment (such as glass washers). Currently, most of the above surface cleaning equipment are equipped with a host and a charging base, wherein the host is provided with a charging docking structure, and the base is also provided with a corresponding charging docking structure. When the host is placed on or close to the base, the two charging docking structures are connected to charge the host. The above-mentioned structure of quickly connecting and charging through two corresponding charging docking structures is collectively referred to as a charging quick-connect structure. In addition, in addition to charging, some charging quick-connect structures can also achieve signal connectivity to transmit signals between the host and the base.

[0003] In the prior art, charging quick-connect structures are prone to rusting when exposed to the air for a long time, resulting in poor contact. In addition, these charging quick-connect structures are mostly concave and convex matching connection structures, which means that some charging quick-connect structures with communication connections need to be configured with a larger volume to accommodate these functions, which is not conducive to small-size structural design.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] Please refer to the attached Figure 1-8As shown, a charging quick-connect structure provided by an embodiment of the present invention includes a groove 11 provided on a first main body 10 and a boss 21 provided on a second main body 20, wherein a positive pole contact convex structure 22 is provided on one side wall of the boss 21, a negative pole contact convex structure 23 is provided on the side wall opposite thereto, and a signal contact piece 24 is provided on the side wall adjacent thereto, wherein the positive pole contact convex structure 22 and the negative pole contact convex structure 23 can be elastically and telescopically arranged between the inside and outside of the boss 21, and the signal contact piece 24 is fixed to the side wall of the boss 21; a positive pole contact piece is provided on the side wall of the groove 11 corresponding to the position of the positive pole contact convex structure 22 12, a negative contact piece 13 is provided on the side wall corresponding to the negative contact structure 23, and a signal connection post 14 is provided on the side wall corresponding to the signal contact piece 24. The signal connection post 14 can be elastically and telescopically arranged between the interior of the groove 11 and the interior of the first body 10. The positive contact piece 12 and the negative contact piece 13 are fixed to the side wall of the groove 11. When connecting power, the boss 21 fits snugly into the groove 11, the positive contact structure 22 abuts the positive contact piece 12, the negative contact structure 23 abuts the negative contact piece 13, and the signal connection post 14 abuts the signal contact piece 24. By using a docking structure that adapts the boss 21 to the groove 11 for alignment, the positive and negative contact and signal connection structures are arranged on different side walls, fully utilizing space. This allows the groove 11 and boss 21 to be accommodated without being too large, thereby helping to reduce the volume of the charging quick-connect structure. In addition, the positive pole contact structure 22, the negative pole contact structure 23 and the signal connection column 14 all adopt an elastic telescopic design, so that they can scratch their respective contact pieces during the electrical connection process. In this way, even if there is dust or rust on the surface of the contact piece, it can be scratched, thereby ensuring the reliability of the connection. Therefore, the charging quick connection structure can reduce the occurrence of poor contact caused by rust.

[0030] Optionally, the boss 21 is shaped like a trapezoid, with a smaller top and a larger bottom.

The recess 11 is shaped to match the boss 21, with the positive and negative contact pieces 12 and 13 arranged parallel to the sidewalls of the recess 11, and the signal connection post 14 is arranged perpendicular to the sidewalls of the recess 11. With the trapezoidal boss 21, which is shaped like a smaller top and a larger bottom, water that falls onto the positive and negative contact structures 22 and 23, as well as the signal contact piece 24, will automatically slide down the inclined surface during normal use, thereby reducing the risk of rust. Furthermore, the trapezoidal shape facilitates docking and undocking operations. This structure also helps improve the scraping force on the contact pieces during connection, thereby improving dust and rust removal.

[0031] Optionally, the positive pole electrical contact structure 22 and the negative pole electrical contact structure 23 adopt the same structure, which include an insulating telescopic block 201, a metal conductive sheet 202 and a telescopic spring 203. A spring groove 207 is provided on the inner side of the insulating telescopic block 201, and one end of the telescopic spring 203 is provided in the spring groove 207.

The metal conductive sheet 202 covering the outer side of the insulating telescopic block 201 is also provided with an electrical connection protrusion 204.

[0032] Optionally, the boss 21 is provided with an installation groove 27 for installing the insulating telescopic block 201 on the side wall where the positive pole electrical contact structure 22 and the negative pole electrical contact structure 23 are respectively provided. When the insulating telescopic block 201 is installed in the installation groove 27, the side of the insulating telescopic block 201 covered with the metal conductive sheet 202 faces outward, and the side of the insulating telescopic block 201 provided with the telescopic spring 203 faces inward.

[0033] Optionally, the interior of the boss 21 is further provided with a butt plate 26 , and the respective telescopic springs 203 of the positive electrode convex contact structure 22 and the negative electrode convex contact structure 23 are respectively pressed against the butt plate 26 .

[0034] Optionally, a side of the insulating expansion block 201 is provided on a limiting step 205 , and an outer side of the limiting step 205 abuts against an inner side of the mounting groove 27 .

[0035] Optionally, the signal contact piece 24 is set as a metal piece, and a mounting hole 25 is provided on the boss 21. A portion of the signal contact piece 24 is tightly attached to a position set on the side wall of the boss 21, and the other portion extends along the side wall of the boss 21 and passes through the mounting hole 25 into the boss 21 to form a signal connection terminal 208.

[0036] Optionally, the positive contact sheet 12 and the negative contact sheet 13 are both set as metal sheets, and the positive contact sheet 12 and the negative contact sheet 13 are partially tightly attached to the position set on the side wall of the groove 11, and the other parts extend along the side wall of the groove 11 and penetrate into the first main body 10 to form the second connection end 102.

[0037] Optionally, a second hole 101 is provided on the side wall of the groove 11 in which the signal connecting column 14 is provided. The signal connecting column 14 is embedded in the second hole 101 , and the outer end of the signal connecting column 14 passes through the second hole 101 , and the inner end of the signal connecting column 14 abuts against the second spring 15 .

[0038] An embodiment of the present invention further provides a cleaning device, comprising a main body and a charging base, wherein the cleaning device is provided with a quick-connect charging structure as described above, wherein the main body is set as the first main body 10 and the charging base is set as the second main body 20.

[0039] The charging quick-connect structure of the present invention utilizes a docking structure in which the boss 21 and the groove 11 are aligned, with the positive and negative pole connections and signal connection structures positioned on separate sidewalls. This fully utilizes space, allowing the groove 11 and boss 21 to be accommodated without requiring a large volume, thereby helping to reduce the size of the charging quick-connect structure. Furthermore, the positive pole contact structure 22, the negative pole contact structure 23, and the signal connection post 14 all utilize an elastic design, allowing them to scrape against their respective contact pads during the electrical connection process. This allows them to be scraped even if the contact pads are dusty or rusty, thereby ensuring connection reliability.
