[0021] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0022] like Figure 1-6A window cleaning robot comprises an outer shell 1, a bottom shell 2, a floating plate 3 and a connecting member 4, wherein the bottom shell 2 is connected to the outer shell 1 to form an installation cavity 10 between the outer shell 1 and the bottom shell 2, a first groove 31 is formed at the floating plate 3, and a first through hole 311 is provided at the bottom of the first groove 31, a second through hole 211 is formed on the bottom shell 2, and a connecting column 11 is formed by the outer shell 1 passing through the installation cavity 10, the second through hole 211 and the first through hole 311 extending toward the first groove 31, the connecting member 4 comprises a connecting body and an abutting edge extending outward from the connecting body, the connecting body extends into the connecting column 11, and the abutting edge abuts against the edges around the first through hole 311 to connect the floating plate 3 to the outer shell 1, and form a motion spacing between the floating plate 3 and the bottom shell 2.

[0023] The utility model provides a window cleaning robot, wherein the bottom shell 2 is fixedly connected to the outer shell 1, the floating plate 3 is abutted against the edges of the first through hole 311 by the abutting edge of the connecting member 4, and the main body of the connecting member 4 extends into the connecting column 11, so as to connect the floating plate 3 to the outer shell 1, and form a moving distance between the floating plate 3 and the bottom shell 2, so that the floating plate 3 can move closer to or away from the bottom shell 2. The floating plate is connected to the outer shell 1, which can ensure that the floating plate can move closer to or away from the bottom shell, and the floating plate is installed more firmly, avoiding the situation that the floating plate is only connected to the bottom shell and the floating plate needs to move relative to the bottom shell, resulting in loose connection and easy damage.

[0024] In this embodiment, the bottom shell 2 is between the floating plate 3 and the outer shell 1 .

[0025] In this embodiment, the bottom shell 2 is fixedly connected to the outer shell 1 by fixing screws.

[0026] The floating plate 3 is recessed toward the bottom shell 2 to form a first groove 31 , and the first through hole 311 is provided at the bottom of the first groove 31 .

[0027] The bottom shell 2 is recessed toward the outer shell 1 to form a second groove 21 , and a second through hole 211 is formed at the bottom of the second groove 21 .

[0028] A spring 5 is disposed in the second groove 21 , and one end of the spring 5 contacts the bottom of the second groove 21 , and the other end of the spring 5 contacts the outer wall of the first groove 31 .

[0029] When the floating plate 3 moves toward the bottom shell 2, the first groove 31 extends into the second groove 21, the first through hole 311 moves along the connecting column 11, and the spring 5 contracts; when the spring 5 restores its elastic deformation, it drives the floating plate 3 to move away from the bottom shell 2.

[0030] The width of the second groove 21 is greater than the width of the first groove 31. When the floating plate 3 moves closer to the bottom shell 2, the first groove 31 can extend into the second groove 21, thereby avoiding collision between the bottom shell 2 and the floating plate 3.

[0031] In this embodiment, the diameter of the second through hole 211 is equal to or slightly larger than the diameter of the cross section of the connecting column 11. When the floating plate 3 moves toward or away from the bottom shell 2, the second through hole 211 can guide the movement of the connecting column 11 to prevent the floating plate 3 from deviating during movement.

[0032] An extended edge is extended upwardly from the first through hole 311 , and the through hole and the extended edge cooperate with the outer wall of the connecting post 11 to guide the connecting post 11 .

[0033] A connecting cavity is formed in the connecting column 11, and the connecting member 4 extends into the connecting cavity.

[0034] In this embodiment, when the floating plate 3 is in a state away from the bottom shell 2, the lower end face of the connecting column 11 is flush with the first perforation 311, that is, the horizontal plane where the lower end face of the connecting column 11 is located is flush with the horizontal plane where the lower end face of the first perforation 311 is located, so that when the connecting member 4 is connected to the connecting column 11, when the connecting column 11 body extends into the connecting column 11, the abutting edge just contacts and abuts with the surrounding edges of the first perforation 311, avoiding the problem of a gap between the abutting edge and the edge of the first perforation 311, which would cause noise when the window cleaning robot is carried.

[0035] In some embodiments, the horizontal plane where the lower end surface of the connecting column 11 is located is slightly higher than the horizontal plane where the lower end surface of the first through hole 311 is located, that is, the connecting column 11 is arranged in the first through hole 311 but does not pass through the first through hole 311 into the first groove 31.

[0036] The connecting post 11 passes through the second through hole 211 of the second groove 21 of the bottom shell 2 and the first through hole 311 of the first groove 31 .

[0037] In some embodiments, the connecting member 4 comprises a connecting screw.

[0038] In this embodiment, the connecting column 11 includes a first connecting portion 111 and a second connecting portion 112, wherein the first connecting portion 111 is at one end close to the housing 1, and the second connecting portion 112 is at one end close to the bottom shell 2 and the floating plate 3. The cross-sectional width of the second connecting portion 112 is smaller than the cross-sectional width of the first connecting portion 111. This ensures that the connection between the connecting column 11 and the housing 1 is stable, and ensures that the connecting column 11 is still stable during the movement of the floating plate 3, so as to avoid affecting the normal operation of the window cleaning robot due to the unstable connection of the connecting column 11.

[0039] The spacing distance between the bottom shell 2 and the floating plate 3 is a first spacing distance, and the spacing distance between the bottom of the first groove 31 and the bottom of the second groove 21 is a second spacing distance, and the second spacing distance is greater than the first spacing distance. This is formed by the depression depth of the second groove 21 being greater than the depression depth of the first groove 31.

[0040] The above-mentioned preferred implementation modes should be regarded as illustrative examples of the implementation modes of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on this scheme should be regarded as within the scope of protection of this patent.
