[0032] In the following description of the present utility model, the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating that the device must have a specific orientation.

[0033] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model is further elaborated below in conjunction with specific illustrations.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0035] The utility model aims to provide a rotatable electrode 1 system, which includes an electrode 1 and an electrode 1 steering structure. The electrode 1 is arranged in an electrode mounting seat 2 through the electrode 1 steering structure. The electrode 1 includes a charging end 1a and a wiring end 1b. Let the front end of the electrode 1 be the charging end 1a and the rear end of the electrode 1 be the wiring end 1b. The wiring end 1b of the electrode 1 passes through a sphere 3. The front side of the sphere 3 abuts against the front cover plate of the electrode mounting seat 2, and the rear side of the sphere 3 abuts against the electrode 1 steering structure and can rotate arbitrarily within a certain angle. The charging electrode 1 can rotate 360° within the plane where the electrode mounting seat 2 is located, and can adapt to various installation scenarios such as intelligent lawn mowers and floor sweeping robots.

[0036] The electrode 1 steering structure includes a first steering frame and a second steering frame. A first kidney-shaped groove 4a through which the wiring end 1b of the electrode 1 passes is provided at the center of the first ball socket of the first rotating frame 4, and a second kidney-shaped groove 9a through which the wiring end 1b of the electrode 1 passes is provided at the center of the second ball socket of the second rotating frame 9.

[0037] The rear side of the sphere 3 abuts against the first ball socket in the middle of the first rotating frame 4. The sphere 3 rotates along the opening direction of the first kidney-shaped groove 4a, and the first ball socket rotates along the opening direction of the second kidney-shaped groove 9a of the second ball socket. The movement stroke of the wiring end 1b in the kidney-shaped groove limits the movement stroke of the charging end 1a. Since the length of the charging end 1a is much longer than that of the wiring end 1b, a very small displacement of the wiring end 1b can cause a large displacement of the charging end 1a.

[0038] The first rotating frame 4 and the second rotating frame 9 are perpendicular to each other and at least part of the projections of the first ball socket and the second ball socket on the front cover plate of the electrode mounting seat 2 overlap. The first rotating frame 4 can abut against the second rotating frame 9 or be far away from the second rotating frame 9. The greater the distance between the first rotating frame 4 and the second rotating frame 9, the greater the moving angle of the electrode 1. When the first rotating frame 4 abuts against the second rotating frame 9, the electrode 1 can rotate arbitrarily within 60°.

[0039] Both ends of the first rotating frame 4 are respectively provided with first rotating frame bending parts 4b, and the two first rotating frame bending parts 4b are respectively hinged to the electrode mounting seat 2; the center of the outer wall of one first rotating frame bending part 4b is connected with a first rotating frame hinge head 4c, and the center of the outer wall of the other first rotating frame bending part 4b is connected with a first rotating shaft 4d; a first rotating frame reset mechanism is installed on the first rotating shaft 4d, and a second rotating frame reset mechanism is installed on the second rotating shaft.

[0040] Both ends of the second rotating frame 9 are respectively provided with second rotating frame bending parts 9b, and the two second rotating frame bending parts 9b are respectively hinged to the electrode mounting seat 2. The center of the outer wall of one second rotating frame bending part 9b is connected with a second rotating frame hinge head 9c, and the center of the outer wall of the other second rotating frame bending part 9b is connected with a second rotating shaft.

[0041] The first turret reset mechanism includes a first turret inner travel plate 5, a first turret outer travel plate 6, and a first turret limit plate 7 that are sequentially sleeved on the first rotating shaft 4d from the inside out. One side of the first turret inner travel plate 5 is provided with an inner travel plate cantilever that extends backward. The other side of the first turret outer travel plate 6 is provided with an outer travel plate cantilever that extends backward. The free end of the inner travel plate cantilever is connected to the free end of the outer travel plate cantilever through a first turret reset spring 8. The first turret reset mechanism includes a first turret inner travel plate 5, a first turret outer travel plate 6, and a first turret limit plate 7 that are sequentially sleeved on the first rotating shaft 4d from the inside out.

[0042] One side of the first turret inner travel plate 5 is provided with an inner travel plate cantilever that extends backward. The other side of the first turret outer travel plate 6 is provided with an outer travel plate cantilever that extends backward. The free end of the inner travel plate cantilever is connected to the free end of the outer travel plate cantilever through a first turret reset spring 8.

[0043] The circumferential wall of the first rotating shaft 4d is provided with a plurality of first convex ribs 4e along the axial direction. Each first convex rib 4e is respectively embedded in the travel limit grooves of the first turret inner travel plate 5 and the first outer travel plate. The width of each travel limit groove is greater than the width of the corresponding first convex rib 4e, so that the first turret inner travel plate 5 and the first outer travel plate can rotate a certain angle relative to the first rotating shaft 4d.

[0044] One side edge of the first turret inner travel plate 5 is provided with an inner travel plate limit step. One side edge of the first turret outer travel plate 6 is provided with an outer travel plate limit step. A travel plate opening is formed between the inner travel plate limit step and the outer travel plate limit step.

[0045] The first turret limit plate 7 is provided with a first limit insertion block 7a that extends towards the two first travel plates. The first limit insertion block 7a is inserted into the travel plate opening and supported between the inner travel plate limit step and the outer travel plate limit step.

[0046] The second turret reset mechanism includes a second turret inner travel plate, a second turret outer travel plate, and a second turret limit plate 10 that are sequentially sleeved on the second rotating shaft.

[0047] One side of the second turret inner travel plate is provided with an inner travel plate cantilever that extends backward. The other side of the second turret outer travel plate is provided with an outer travel plate cantilever that extends backward. The free end of the inner travel plate cantilever is connected to the free end of the outer travel plate cantilever through a second turret reset spring 11.

[0048] The circumferential wall of the second rotating shaft is axially provided with a plurality of second convex ribs, and each second convex rib is respectively embedded in the travel limit grooves of the inner travel plate and the outer travel plate of the second rotating frame. The width of each travel limit groove is greater than the width of the corresponding second convex rib, so that the inner travel plate and the outer travel plate of the second rotating frame can rotate a certain angle relative to the second rotating shaft. This prevents the distance between the two cantilevers from exceeding the maximum travel of the return spring due to the excessive rotation angle of the charging end 1a of the electrode 1, resulting in the inability of the return spring to reset.

[0049] One side edge of the inner travel plate of the second rotating frame is provided with an inner travel plate limit step, and one side edge of the outer travel plate of the second rotating frame is provided with an outer travel plate limit step. A travel plate opening is formed between the inner travel plate limit step and the outer travel plate limit step; the second rotating frame limit plate 10 is provided with second limit inserts extending towards the two second travel plates. The second limit inserts are inserted into the travel plate opening and supported between the inner travel plate limit step and the outer travel plate limit step to prevent the return spring from falling off.

[0050] The utility model reduces the risk of physical damage caused by inaccurate docking of the charging electrode 1 and the charging socket; improves the electrical connection quality and ensures a stable and reliable power supply; thus enhancing the user experience satisfaction.

[0051] The above are only the preferred and feasible embodiments of the utility model, which show and describe the basic principles, main features and advantages of the utility model. The patent protection scope of the utility model is not limited thereby. Those skilled in the art should understand that the utility model is not restricted by the above embodiments. Except for the above embodiments, without departing from the spirit and scope of the utility model, the utility model can also have other implementation manners.
