[0001] The utility model relates to the technical field of window-cleaning robots, and in particular to a connection structure and a window-cleaning robot having the same. Background Art

[0002] A window typically comprises a glass panel and a window frame surrounding the glass panel. The window frame generally protrudes horizontally from the glass panel, forming a step between the frame and the glass panel. A window cleaning robot comprises a bottom shell and a floating plate, which are connected by a connecting structure. This connection allows the floating plate to move toward or away from the bottom shell. When the window cleaning robot is cleaning a glass panel near one end of the window frame, the connecting structure and the floating plate can easily get stuck with the edge of the window frame, causing the window cleaning robot to malfunction. Utility Model Content

[0003] The present invention solves one of the problems existing in the existing related technologies to a certain extent. To this end, one purpose of the present invention is to propose a connecting structure, which forms sufficient avoidance space between the connecting structure and the floating plate to avoid jamming.

[0004] The above purpose is achieved through the following technical solutions:

The main body includes a first body and a second body, the first body is connected to the connecting rod, and the second body is connected to the first body. The cross-section of the second body gradually narrows from one end close to the first body to the end away from the first body, forming an arc edge at the outer edge of the second body.

[0006] As a further improvement of the present invention, the second main body includes a first connecting portion, a second connecting portion and a third connecting portion, the first connecting portion is connected to the first main body, and the second connecting portion is between the first connecting portion and the third connecting portion.

[0007] As a further improvement of the present invention, the outer edge of the cross section of the first connecting portion is a first arc, the outer edge of the cross section of the second connecting portion is a second arc, the radius of the first arc is R1, the radius of the second arc is R2, and R2 is greater than R1.

[0008] As a further improvement of the present invention, the outer edge of the cross section of the third connecting portion 53 is a third arc, and the radius of the third arc is R3, where R3 is greater than R1 and smaller than R2.

[0025] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0026] Example 1:

[0027] like Figure 1-4 A connecting structure 1 includes a connecting rod 2 and a main body 3, one end of the main body 3 is connected to the connecting rod 2, and the other end extends away from the connecting rod 2. The main body 3 includes a first main body 4 and a second main body 5, the first main body 4 is connected to the connecting rod 2, and the second main body 5 is connected to the first main body 4. The cross-section of the second main body 5 gradually narrows from one end close to the first main body 4 to the end away from the first main body 4, forming an arc edge at the outer edge of the second main body 5.

[0028] The present utility model proposes a connecting structure 1, which is used on a window-cleaning robot. The connecting structure 1 connects a bottom shell and a floating plate, and extends outward from the floating plate. The cross-section of the second main body 5 of the main body gradually narrows from one end close to the first main body 4 to the end far away from the first main body 4, so as to form a sufficient avoidance space between the connecting structure 1 and the floating plate, so as to avoid the situation that when the window-cleaning robot is performing window cleaning work and wiping the window glass close to the window frame, the avoidance space between the connecting structure 1 and the floating plate is too small, causing the robot to get stuck and fail to work normally, thereby avoiding the situation of the window frame being stuck.

[0029] The second body 5 is at the end away from the connecting rod 2, and the cross-section of the second body 5 gradually narrows from the end close to the first body 4 to the end away from the first body 4, so that the second body 5 protrudes outward, and the outer edge of the second body 5 is arc-shaped and smooth, so that when the window cleaning robot is working, the connecting structure 1 can pass smoothly when it touches foreign objects, reducing friction.

[0030] The second body 5 includes a first connecting portion 51, a second connecting portion 52, and a third connecting portion 53. The first connecting portion 51 is connected to the first body 4, and the second connecting portion 52 is between the first connecting portion 51 and the third connecting portion 53. From top to bottom, the second body 5 includes the third connecting portion 53, the second connecting portion 52, and the first connecting portion 51.

[0031] The first connection portion 51 gradually narrows from bottom to top, the second connection portion 52 gradually narrows from bottom to top, and the third connection portion 53 gradually narrows from bottom to top.

[0032] The outer edge of the cross section of the first connecting portion 51 is a first arc 511 , and the outer edge of the cross section of the second connecting portion 52 is a second arc 521 . The radius of the first arc 511 is R1 , and the radius of the second arc 521 is R2 , and R2 is greater than R1 .

[0033] The first arc-shaped edge is an arc-shaped edge formed by a circle with a radius of R1 and an arc angle of a°; the second arc-shaped edge is an arc-shaped edge formed by a circle with a radius of R2 and an arc angle of b°; wherein R2 is greater than R1, and a is greater than or equal to b.

[0034] The radius of the first curved edge is relatively small, resulting in a relatively large narrowing as it extends upward from the second body 5. The first connecting portion 51 continues to extend upward to form the second connecting portion 52, and the radius of the second curved edge of the second connecting portion 52 is relatively large, that is, the second connecting portion 52 continues to narrow as it extends upward, and the narrowing is relatively gradual.

[0035] The outer edge of the cross section of the third connecting portion 53 is a third arc 531 , and the radius of the third arc 531 is R3 , where R3 is greater than R1 and smaller than R2 .

[0036] The third arc-shaped edge is an arc edge formed by a circle with a radius of R3 and an arc angle of c°, and c is greater than b and c is greater than a.

[0037] The second connection portion 52 extends upward to form a third connection portion 53 . R3 of the third connection portion 53 is smaller than R2 , that is, the third connection portion 53 narrows more in the upward extension than the second connection portion 52 .

[0038] The height of the first connecting portion 51 in the vertical direction is H1, and the height of the second connecting portion 52 in the vertical direction is H2, and H2 is greater than H1.

[0039] The height of the third connection portion 53 in the vertical direction is H3, and H3 is smaller than H2, and H3 is greater than or equal to H1.

[0040] In this embodiment, the cross section of the second body 5 is in a triangular shape.

[0041] The cross-section of the first body 4 remains constant from the end close to the connecting rod 2 to the end close to the second body 5. In this embodiment, the cross-section of the first body 4 is square.

[0042] Example 2:

[0043] like Figure 5-7 A window cleaning robot 200 includes a bottom shell, a floating plate and a connecting structure 1 described in Example 1. The bottom shell and the floating plate are connected by the connecting structure 1, and an avoidance gap is formed between the floating plate and the connecting structure 1.

[0044] A window generally has a glass plate 300 and a window frame 301 around the glass plate. The window frame generally protrudes from the glass plate in a horizontal plane, so that a step portion 302 is formed between the window frame and the glass plate. When the window cleaning robot is cleaning the window and is cleaning the glass plate near one end of the window frame, the connecting structure 1 and the floating plate are easily engaged with the window frame. Figure 7 The present invention avoids locking and makes the transition smooth by connecting the arc edge of the second main body 5 of the structure 1.

[0045] The above preferred embodiments should be regarded as examples of the implementation methods 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 it should be regarded as within the scope of protection of this patent.
