[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figures 1 to 3 A robot charging device for charging a sweeping robot is shown, comprising a charging pile housing 3. Two guide plates 2 are fixedly connected to both sides of the charging pile housing 3, and the two guide plates 2 are both horizontally arranged and symmetrically distributed on both sides of the charging pile housing 3. The two guide plates 2 are slidably engaged with the sweeping robot body 1, and are used to guide and limit the sweeping robot body 1.

[0022] A charging interface 11 is fixedly installed at the rear of the robot vacuum cleaner body 1. A charging head 7 is movably installed in the charging pile housing 3, and the charging head 7 slides out of the charging pile housing 3 and is electrically plugged into the charging interface 11. A power source is fixedly installed in the charging pile housing 3, and the charging head 7 is electrically connected to the power source through a flexible wire for charging. The flexible wire and the power source are not shown in the figure.

[0023] The charging head 7 in the figure is a simplified drawing. The charging head 7 includes an outer rectangular protective shell and a charging component fixed inside the protective shell with screws. The context of this book is summarized and described in terms of the charging head 7.

[0024] A rectangular installation cavity is dug out inside the charging pile shell 3. A rectangular through hole and a rectangular opening are drilled on the charging pile shell 3 along the moving direction of the sweeping robot body 1 between the two guide plates 2. The rectangular through hole runs through the entire charging pile shell 3 and is connected to the installation cavity. The rectangular opening passes through the front end of the charging pile shell 3 and is connected to the installation cavity. The rectangular through hole is located at the upper part of the charging pile shell 3, and the rectangular opening is located at the middle and lower part of the charging pile shell 3. When the sweeping robot body 1 moves between the two guide plates 2, the rectangular opening is opposite to the charging interface 11, which is used to guide the charging head 7.

[0025] The charging head 7 matches the rectangular opening and is limitedly slidably matched with the charging pile housing 3. The first rack is welded and fixed on the top of the charging head 7, and the bottom of the charging head 7 is in sliding contact with the bottom inner wall of the charging pile housing 3. Both sides of the first rack parallel to the sliding direction of the charging head 7 are in sliding contact with the inner wall of the charging pile housing 3 to ensure that the charging head 7 does not move horizontally in directions other than the sliding direction. The first rack is used to drive the charging head 7 to slide forward or backward.

[0026] The first rack meshes with the gear 8 for transmission, and the inner circumference of the gear 8 is rotatably sleeved with a rotating shaft 9 for support, and the rotating shaft 9 is fixedly connected to the charging pile housing 3. The gear 8 and the rotating shaft 9 are both located in the installation cavity.

[0027] The front end of the first rack is fixedly connected to the limit block 6, and the limit block 6 is welded and fixed on the charging head 7. When the charging head 7 slides forward, the limit block 6 abuts and limits the charging pile housing 3 to ensure that the part of the charging head 7 that passes through the charging pile housing 3 is just firmly and completely plugged into the charging interface 11. When the charging head 7 slides backward, the limit block 6 abuts and limits the teeth of the gear 8 to prevent the charging head 7 from sliding backward too far and causing the gear 8 to disengage from the first rack. The horizontal length of the limit block 6 from back to front is much greater than the pitch of the gear 8.

[0028] The charging pile housing 3 is limitedly slidably matched with the sliding rod 4, which is located in and matched with the rectangular through hole of the charging pile housing 3. The sliding rod 4 runs through the entire charging pile housing 3 and extends horizontally forward out of the charging pile housing 3. The front end of the sliding rod 4 touches and abuts against the sweeping robot body 1 and drives and cooperates, so as to drive the sliding rod 4 to slide backward.

[0029] The horizontal center axis of the sliding rod 4 is parallel to the horizontal center axis of the charging head 7. The length of the sliding rod 4 extending from the charging pile housing 3 is the same as the sliding length of the charging head 7.

[0030] The bottom of the sliding rod 4 is fixedly welded with a second rack, which is located in the mounting cavity and meshes with the gear 8. Both sides of the second rack parallel to the sliding direction of the sliding rod 4 are in sliding contact with the inner wall of the charging pile housing 3 to ensure that the sliding rod 4 does not move laterally in directions other than the sliding direction. The second rack is used to drive the gear 8 to rotate.

[0031] A rectangular protrusion is fixedly welded on the upper end of the sliding rod 4, and the rectangular protrusion is slidably engaged in a slot, which is opened at the top of the charging pile housing 3, and the slot is vertically downward and connected to the installation cavity. The length of the slot along the sliding direction of the rectangular protrusion is the same as the sliding length of the charging head 7. The rectangular protrusion is used to limit the sliding of the sliding rod 4 to prevent the two ends of the sliding rod 4 from being out of contact with the charging pile housing 3.

[0032] A spring 10 is sleeved on the rear end of the sliding rod 4, the rear end of the spring 10 is fixedly connected to the charging pile housing 3, and the front end of the spring 10 is not only fixedly connected to the sliding rod 4 but also abuts against the rectangular protrusion and the second rack. The spring 10 is always in a compressed state and is used to reset the sliding rod 4.

[0033] The installation cavity of the charging pile housing 3 is a rectangular opening in which a baffle 5 is slidably mounted, and the baffle 5 is in limited sliding cooperation with the charging pile housing 3. The baffle 5 is placed vertically and can slide up and down in the installation cavity to ensure that the rectangular opening can be fully covered and released. The rear end of the baffle 5 is welded and fixed with a third rack, and the third rack is meshed with the gear 8. Both sides of the third rack parallel to the sliding direction of the baffle 5 are in sliding contact with the inner wall of the charging pile housing 3, and the front end of the baffle 5 is in sliding contact with the front inner wall of the charging pile housing 3, ensuring that the baffle 5 does not move laterally in directions other than the sliding direction.

[0034] The limiting block 6 on the top of the charging head 7 and the rectangular protrusion on the top of the sliding rod 4 directly or indirectly limit the rotation of the gear 8, thereby indirectly ensuring that the third rack on the baffle 5 is not separated from the gear 8.

[0035] When the limit block 6 abuts against the teeth of the gear 8, the bottom of the baffle 5 abuts against the bottom inner wall of the charging pile shell 3. At this time, there is a certain distance between the charging head 7 and the baffle 5, ensuring that the sliding process of the charging head 7 and the baffle 5 does not cross contact and affect each other.

[0036] In the figure, the guide plate 2, the charging pile housing 3 and the sliding rod 4 are all insulators.

[0037] Working principle:

[0038] When charging is needed, the sweeping robot body 1 automatically moves toward the charging pile housing 3. When it moves to the two guide plates 2, the two guide plates 2 will slide and engage the sweeping robot body 1 and guide it. Then the sweeping robot body 1 continues to move to contact the sliding rod 4, and the sliding rod 4 slides backward in the rectangular through hole of the charging pile housing 3. At this time, the sliding rod 4 compresses the spring 10, and the second rack on the sliding rod 4 makes the gear 8 rotate counterclockwise.

[0039] The counterclockwise rotation of the gear 8 will simultaneously cause the baffle 5 to slide upward inside the charging pile housing 3, and the charging head 7 to slide forward and gradually slide out of the rectangular opening on the charging pile housing 3. At this time, the baffle 5 releases the full cover of the rectangular opening on the charging pile housing 3, and thus does not block the charging head 7. The charging head 7 and the cleaning robot body 1 are close to each other until the charging head 7 passes through the rectangular opening on the charging pile housing 3 and is fully and firmly plugged into the charging interface 11 at the rear end of the cleaning robot body 1. At this time, the cleaning robot body 1 stops moving and starts charging.

[0040] At this time, the limit block 6 abuts against the charging pile housing 3 .

[0041] When the cleaning robot body 1 is fully charged, the cleaning robot body 1 moves away from the charging pile housing 3. At this time, the sliding rod 4 will slide forward under the elastic force of the spring 10 until it is reset. During the extension process, the gear 8 will rotate clockwise, thereby driving the charging head 7 to slide backward, so that the charging head 7 is out of contact with the charging interface 11 and gradually moves away from the cleaning robot body 1. At the same time, the movable baffle 5 slides downward, and when the charging head 7 completely enters the charging pile housing 1, the movable baffle 5 completely covers the rectangular opening, thereby protecting the charging head 7.

[0042] At this time, all components are reset, the limit block 6 abuts against the gear 8, and the baffle 5 abuts against the charging pile housing 3, preparing for the next charging.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
