In order to facilitate the processing of the second connection hole 215, the second connection hole 215 may be formed on the first ear portion 216 and the second ear portion 217.
It should be noted that if the wiper assembly 200 is installed in reverse, the relative positions of the first wiper strip 221 and the second wiper strip 222 are reversed, which in turn results in water on the surface to be cleaned being blocked by the first wiper strip 221 outside the suction gap 223. In this way, the cleaning effect of the wiper assembly 200 is reduced, and the recovery of the contaminated water is also not facilitated. Thus, in some embodiments, the positioning of the wiper assembly 200 and the avoidance of reverse loading may be achieved by changing the arrangement of the first ear 216 and the second ear 217.
For example, referring to fig. 2 and 3, the base plate 210 may have a first ear 216 at one end and a second ear 217 at the other end, and the first ear 216 and the top wall of the suction cavity 211 are provided with a second connection hole 215; alternatively, the other end of the base plate 210 is provided with a second ear portion 217, one end of the base plate 210 is not provided with the first ear portion 216, and the second ear portion 217 and the top wall of the suction cavity 211 are provided with the second connecting hole 215. Thus, confusion during installation can be avoided.
Alternatively, one end of the substrate 210 is provided with a first ear portion 216, the other end of the substrate 210 is provided with a second ear portion 217, and the shapes of the first ear portion 216 and the second ear portion 217 may be different. For example, the first ear 216 may be semi-circular and the second ear 217 may be square. And on the mounting position of the chassis 400 corresponding to the first ear 216 and the second ear 217, a groove for assisting in mounting may be provided corresponding to the shape of the first ear 216 or the second ear 217, respectively. Thus, the mounting positions of the first lug 216 and the second lug 217 are conveniently distinguished, the reverse installation of the wiper assembly 200 is avoided, and the positioning and mounting are realized.
It can be appreciated that when only the first ear 216 or the second ear 217 are disposed on the substrate 210, the material usage for producing the substrate 210 can be reduced, and the economic benefit can be improved; when the first and second ears 216 and 217 are provided on the base plate 210, the connection strength of the base plate 210 and the chassis 400 can be improved. Accordingly, the first ear 216 and the second ear 217 may be provided according to actual use requirements.
