[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] Embodiment 1:

[0045] like Figures 1 to 5 As shown, the charging base station proposed in the embodiment of the utility model is used for charging the intelligent lawn mower 400. The charging base station includes a housing 100 and a charging component and a charging terminal 200 arranged in the housing 100, and the charging terminal 200 is electrically connected to the charging component. The housing 100 includes a suspended portion 110 and a supporting portion 111 supporting the suspended portion 110. The charging terminal 200 is installed on the suspended portion 110. The charging terminal 200 includes an end 210 and a limiting portion 211. Part of the end 210 passes through the suspended portion 110 downward and floats relative to the suspended portion 110. The limiting portion 211 limits the charging terminal 200 from being separated from the suspended portion 110 downward. Among them, the suspended portion 110 includes a lower end surface 112, and the end 210 can be retracted relative to the lower end surface 112 to change the length of the extension, so that the height of the charging terminal 200 from the ground can be changed to adapt to intelligent lawn mowers 400 of different heights.

[0046] When the smart lawn mower 400 does not enter the charging base station for charging, the end 210 extends out of the lower end surface 112 to the maximum extent under the action of gravity. When the smart lawn mower 400 enters the charging base station for charging, the smart lawn mower 400 acts on the end 210 of the charging terminal 200 to change its height, so that the charging base station can adapt to smart lawn mowers 400 of different heights. Preferably, the maximum moving distance of the end 210 is 30 to 50 mm, so that the moving distance of the end 210 is large, and it can adapt to a variety of smart lawn mowers 400 of different heights, thereby improving the applicability of the charging base station.

[0047] In order to guide the movement direction of the charging terminal 200 and prevent the charging terminal 200 from being separated from the working position, in one embodiment, a guide portion 120 is provided in the suspended portion 110, and the guide portion 120 includes a guide sleeve 121 and a cover 122. The guide sleeve 121 and the cover 122 form a limiting cavity 123, and the limiting portion 211 can be movably limited in the limiting cavity 123. The guide portion 120 guides the movement of the limiting portion 211 and prevents the charging terminal 200 from being separated from the working position.

[0048] A hole for passing the end portion 210 is provided below the guide portion 120 , and the size of the hole is smaller than the limiting portion 211 to limit the charging terminal 200 from being separated from the limiting cavity 123 .

[0049] In order to prevent the charging terminal 200 from getting stuck on the suspended portion 110 during the extension process and thus being unable to adapt to the smart lawn mower 400 of a certain height, as shown in FIG. Figure 2 As shown, in a preferred embodiment, a spring 130 is provided in the limit cavity 123, and the spring 130 is compressed between the guide portion 120 and the charging terminal 200. The spring 130 acts on the charging terminal 200 with elastic force so that the end 210 has a tendency to extend downward from the lower end surface 112. When the smart lawn mower 400 is charging, the charging terminal 200 is compressed, and part of it is retracted into the limit cavity 123. At this time, the spring 130 is compressed to store energy. After the smart lawn mower 400 is charged and leaves the charging base station, the spring 130 releases and pushes the end 210 of the retracted limit cavity 123 to extend downward. When the charging terminal 200 is stuck in the process of retracting into the limit cavity 123 or extending downward from the limit cavity 123, the thrust of the spring 130 can push the charging terminal 200 to extend, thereby preventing the charging terminal 200 from being stuck on the suspended portion 110 and unable to extend.

[0050] In order to better position the spring 130 in the limiting cavity 123, as shown in FIG. Figure 3As shown, in a more preferred embodiment, a spring positioning end is provided in the guide portion 120, and the spring positioning end forms a first spring positioning end 125. The charging terminal 200 is provided with a spring positioning end, and the spring positioning end forms a second spring positioning end 213. The first spring positioning end 125 and the second spring positioning end 213 are both located in the limiting cavity 123, and the two are arranged oppositely. The two ends of the spring 130 are respectively positioned on the first spring positioning end 125 and the second spring positioning end 213, so that the spring 130 is positioned in the limiting cavity 123 to prevent the spring 130 from being separated from the working position.

[0051] It is understandable that a spring positioning end may be provided on only one of the guide portion 120 and the charging terminal 200 , which can also play the role of positioning the spring 130 .

[0052] In order to better position the spring 130 in the limiting cavity 123, as shown in FIG. Figure 4 As shown, in another more preferred embodiment, the charging terminal 200 is provided with a guide rod 212 in a direction away from the end 210 , the spring 130 is sleeved on the guide rod 212 , and the guide rod 212 extends out of the limiting cavity 123 in a direction away from the end 210 .

[0053] It should be noted that the guide portion 120 is provided with an installation opening 124 for installing the charging terminal 200, and the guide portion 120 is also provided with a cover 122 for blocking the installation opening 124. The installation opening 124 can be provided above the guide portion 120, in which case the cover 122 blocks the upper part of the guide portion 120; the installation opening 124 can also be provided below the guide portion 120, that is, at the lower end surface 112 of the lower cover, in which case the cover 122 blocks the lower part of the guide portion 120; the installation opening 124 can also be provided on the side of the guide portion 120, in which case the cover 122 blocks the side of the guide portion 120.

[0054] The charging base station further includes a base 300, the housing 100 is connected to the base 300, and the base 300 is provided with a plurality of anti-skid protrusions 301. The smart lawn mower 400 being charged is parked on the base 300, and the anti-skid protrusions 301 on the base 300 prevent the smart lawn mower 400 from sliding or moving during charging.

[0055] Embodiment 2:

[0056] Different from the first embodiment, in this embodiment, Figure 8As shown, the guide part 120 is further provided with a limiting groove 140 in the limiting cavity 123, and the height of the limiting groove 140 gradually changes from one end to the other end. The limiting part 211 is slidably matched with the limiting groove 140, and the spring 130 is compressed between the guide part 120 and the charging terminal 200. The limiting groove 140 and the limiting part 211 are used to cooperate to realize the extension and contraction of the charging terminal 200, and the vertical extension and contraction of the charging terminal 200 is converted into oblique extension and contraction, so that the lateral force of the charging terminal 200 when contacting the intelligent lawn mower 400 can be reduced, the shear force of the charging terminal 200 when contacting the guide part 120 can be reduced, and the risk of deformation or even breakage of the charging terminal 200 during use can be reduced.

[0057] In this embodiment, preferably, a sliding member 160 capable of laterally moving is further provided in the limiting cavity 123, and a guide rod 212 is provided on the charging terminal 200 in a direction away from the end 210, the sliding member 160 can be movably mounted on the guide rod 212, and the spring 130 is compressed between the sliding member 160 and the charging terminal 200.

[0058] Specifically, the limiting cavity 123 is also provided with a transversely arranged slide groove 150, and the sliding member 160 can be slidably arranged in the slide groove 150. The charging terminal 200 is telescopically extended along the direction of the limiting groove 140 to drive the guide rod 212 to move left and right, and the guide rod 212 drives the sliding member 160 to move left and right in the slide groove 150.

[0059] Such a configuration enables the guide rod 212 to better drive the spring 130 to move, so that the charging terminal 200 can be better pushed to reset during the release process of the spring 130.

[0060] Embodiment three:

[0061] like Figures 5 to 7 As shown, in one embodiment of the utility model, a smart mowing system is proposed, including a smart mower 400 and a charging base station described in any of the above embodiments, a charging sheet 401 is provided at the upper end of the smart mower 400, the charging sheet 401 contacts the charging terminal 200 so that the charging base station charges the smart mower 400, and the height of the charging sheet 401 gradually changes along the direction in which the smart mower 400 moves. The height change of the charging sheet 401 allows it to be better adapted to the charging terminal 200.

[0062] Preferably, in this embodiment, the extended end portion 210 is inclined in the direction in which the smart lawn mower 400 enters the charging base station.

[0063] Such a configuration can reduce the lateral force on the charging terminal 200 when it contacts the charging plate 401 of the smart lawn mower 400, thereby reducing the shear force on the charging terminal 200 when it contacts the guide part 120, and reducing the risk of deformation or even breakage of the charging terminal 200 during use.

[0064] In this embodiment, the charging terminal 200 is a positive electrode, and the casing 100 is also provided with a negative terminal electrically connected to the charging component. A battery is provided in the smart lawn mower 400, and a negative charging part connected to the battery is provided on the casing of the smart lawn mower 400, and the negative terminal is in contact with the negative charging part.

[0065] With such a configuration, the positive charging sheet 401 at the upper end of the smart lawn mower 400 only needs to be configured as one piece, which can reduce the area occupied by the charging mechanism at the upper end of the smart lawn mower 400; at the same time, there is no need to consider the spacing and tolerance of the positive and negative charging mechanisms, thereby increasing the fault tolerance of the contact between the charging sheet 401 and the charging terminal 200 and reducing the tolerance between the charging sheet 401 and the charging terminal 200.

[0066] More preferably, a plurality of positive charging terminals 200 may be provided on the charging base station, and the charging sheet 401 is in contact with the plurality of positive charging terminals 200 , thereby increasing the charging current of the smart lawn mower 400 and improving the charging speed.

[0067] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation.
