Description

Technical Field

[0001] The utility model relates to the technical field of charging of pure electric washing and sweeping vehicles, in particular to a flexible charging structure of a pure electric washing and sweeping vehicle. Background Art

[0002] Chinese patent CN220594700 U discloses a flexible charging structure for an unmanned sweeper, including a slide rail and a charging device arranged on the slide rail, the slide rail including a horizontal slide rail and a longitudinal slide rail arranged perpendicularly to the horizontal slide rail, the horizontal slide rail including left and right horizontal slide rails and front and rear horizontal slide rails arranged perpendicularly to the left and right horizontal slide rails, and a charging probe is arranged at the end of the charging device. The charging structure has a simple structure and is easy to install. By setting the charging device on the slide rail and utilizing the flexible movement on the slide rail, contact charging at any position can be achieved, which solves the problem of being unable to charge due to irregular parking, improves the convenience and flexibility of charging the unmanned sweeper, and at the same time, probe charging is simple, convenient and more efficient.

[0003] However, because the two charging probes are exposed separately, although a buffer component is set inside the charging probe to avoid hard contact during charging, when the charging device is driven by the slide rail and moves in multiple directions, it is still not possible to ensure that the charging probes will not collide with other parts of the vehicle body. Once the slide rail drives the charging device to move quickly, the charging probes are easily skewed or even broken due to the collision. Utility Model Content

[0030] The working principle and beneficial effects of the above technical solution are:

[0031] The utility model discloses a flexible charging structure for a pure electric washing and sweeping vehicle. After the pure electric washing and sweeping vehicle stops at the charging station, the three-axis transmission assembly drives the charging box 10 to move in space. After the charging box 10 moves to a suitable position, the lifting assembly works, thereby driving the protective plate 12 to rise at the bottom end of the charging box 10, and the charging probe 11 passes through the opening, thereby connecting with the charging port of the pure electric washing and sweeping vehicle to complete the charging operation of the pure electric washing and sweeping vehicle. After the charging is completed, the charging probe 11 is separated from the charging port of the pure electric washing and sweeping vehicle, and the lifting assembly works in reverse, thereby driving the protective plate 12 to descend at the bottom end of the charging box 10, and the charging probe 11 is collected into the protective plate 12 from the opening. The utility model provides a flexible charging structure for a pure electric washing and sweeping vehicle. In the uncharged state, the charging probe 11 is collected into the protective plate 12 from the opening, and the protective plate 12 protects the charging probe 11.

[0032] In one embodiment, the lifting assembly includes:

[0033] The lifting chamber 13 is integrally formed at the bottom of the charging box 10;

[0034] A lifting motor 14 is installed in the lifting chamber 13, and a screw 15 is installed at the output end of the lifting motor 14;

[0035] A lifting plate 16, a screw sleeve is installed on the lifting plate 16, and the screw sleeve is sleeved on the screw rod 15;

[0036] The lifting shell 17 is located in the lifting chamber 13 , the protection plate 12 is connected to the lifting shell 17 , and the lifting plate 16 is installed in the lifting shell 17 .

[0037] The working principle and beneficial effects of the above technical solution are:

[0038] The lifting motor 14 located in the lifting chamber 13 works, thereby driving the screw 15 connected to the output end of the lifting motor 14 to rotate, and the screw 15 cooperates with the screw sleeve to drive the lifting plate 16 connected to the screw sleeve and the lifting shell 17 connected to the lifting plate 16 to perform lifting movements in the lifting chamber 13, thereby realizing the lifting movement of the protection plate 12 connected to the lifting shell 17 at the bottom end of the charging box 10, so as to realize active protection of the charging probe 11.

[0039] In one embodiment, a side end of the lifting housing 17 is slidably connected to an inner wall of the lifting chamber 13 .

[0040] The beneficial effects of the above technical solution are:

[0041] The side end of the lifting shell 17 is slidably connected to the inner wall of the lifting chamber 13 , thereby limiting the lifting of the protection plate 12 .

[0043] The beneficial effects of the above technical solution are:

[0044] The step surface is provided to facilitate the engagement of the side plate 18 therewith, thereby providing a relatively closed protection space when the charging probe 11 is received into the protection plate 12 through the opening.

[0045] In one embodiment, a rotating sleeve 19 is rotatably mounted on the hole wall of the opening, a fine bristle layer 20 is mounted on the inner wall of the rotating sleeve 19 , and the charging probe 11 passes through the fine bristle layer 20 .

[0046] The working principle and beneficial effects of the above technical solution are:
