DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 6 As shown, a wiper assembly for wide-area cleaning includes a wiper assembly body 1. A rubber clip 3 is clamped inside the wiper assembly body 1. A cleaning strip 4 is connected to the underside of the rubber clip 3. The rubber clip 3 can be used to drive the cleaning strip 4 into the interior of the wiper assembly to fix the cleaning strip 4. Four movable rods 5 for fixing the rubber clip 3 are slidably connected to the inner side surface of the wiper assembly body 1.

[0028] A first spring 6 is connected between the four movable rods 5 and the wiper assembly main body 1. A positioning card plate 11 is slidably connected to the right side of the wiper assembly main body 1. Both ends of the positioning card plate 11 are connected with rubber protrusions 14. Through the setting of the rubber protrusions 14, the two rubber protrusions 14 can drive the positioning card plate 11 to be embedded in the groove 8, so that the positioning card plate 11 can support the cleaning strip 4 at the fixed rubber strip 3. A buckle groove 15 is provided on the right side of the rubber protrusion 14. The buckle groove 15 can be used to drive the positioning card plate 11 to be removed from the inside of the wiper assembly so that the cleaning strip 4 can be flexibly replaced. Extension strips 16 are connected to both sides of the rubber strip 3. By using the setting of the extension strip 16, the two extension strips 16 can expand the cleaning range of the cleaning strip 4, so that the cleaning strip 4 and the extension strip 16 can clean the car glass together, thereby improving the cleaning effect.

[0029] A liquid filling port 2 is fixedly connected to the upper side of the wiper assembly main body 1, and an array of drip seats 20 are installed at both ends of the wiper assembly main body 1. The drip seats 20 are distributed in an array on both sides of the wiper assembly. When the wiper assembly is used, the cleaning liquid can be sprayed out from the drip seat 20 faster to expand the spraying range for better cleaning of the car glass and achieving the purpose of wide-area cleaning. The upper side of the liquid filling port 2 is threadedly connected to a threaded cover 10 for sealing the liquid filling port 2.

[0030] Both sides of the wiper assembly main body 1 are clamped with plug plates 12, and one side of the two plug plates 12 is fixedly connected to a positioning seat 13 for fixing the rubber clip 3. The top of the inside of the wiper assembly main body 1 is slidably connected to two telescopic rods 17 for fixing the plug plates 12. A second spring 18 is connected between the two telescopic rods 17 and the wiper assembly main body 1. The upper side of the telescopic rod 17 passes through the wiper assembly main body 1 and extends to the upper side of the wiper assembly main body 1. A connecting support plate 19 is installed on the upper side of the two telescopic rods 17.

[0031] One side of the movable rod 5 passes through the wiper assembly body 1 and extends to one side of the wiper assembly body 1 . A circular plate 7 is installed on one side of each of the four movable rods 5 .

[0032] Two circular grooves 9 are formed at both ends of the rubber clip 3 . The circular grooves 9 are adapted to the movable rod 5 . One side of the movable rod 5 is clamped with the two ends of the rubber clip 3 through the circular grooves 9 .

[0033] Two grooves 8 are formed on the inner side of the wiper assembly body 1 . The grooves 8 match the rubber bumps 14 . One side of the rubber bump 14 is engaged with the inner side of the wiper assembly body 1 through the grooves 8 .

[0034] The working principle of the wiper assembly for wide-area cleaning provided by the utility model is as follows:

[0035] By compressing the movable rod 5 equipped with the first spring 6, the elastic movable rod 5 can be retracted, and then the rubber clip 3 is clipped into the inside of the wiper assembly body 1, so that the rubber clip 3 can drive the cleaning rubber strip 4 to be fixed on the wiper assembly. At this time, the elastic movable rod 5 can automatically extend and clip into the circular groove 9 of the rubber clip 3 to locate the position of the cleaning rubber strip 4. Then, the positioning card 11 is inserted into the inside of the wiper assembly body 1 and the rubber clip 3 to further strengthen the position of the cleaning rubber strip 4 and ensure the stability of the cleaning rubber strip 4 during installation. In this way, the clip connection method can facilitate the rapid replacement of the rubber strip on the wiper assembly, improve the replacement efficiency of the wiper assembly, and save costs at the same time, without having to replace the wiper assembly.

[0036] By adding the cleaning liquid into the cavity of the wiper assembly body 1 along the filling port 2, and then rotating the threaded cover 10 to install it at the filling port 2, as the wiper assembly swings back and forth, the cleaning liquid can be sprayed out through the drip seat 20 to achieve a wide-area cleaning effect, and then the plug-in plate 12 at the positioning seat 13 is clipped to the two ends of the wiper assembly body 1, and then the telescopic rod 17 equipped with the second spring 18 can also position the plug-in plate 12, so that the two positioning seats 13 can support the cleaning strip 4, and at the same time, the use of two extension strips 16 can increase the cleaning area and improve the cleaning effect of the wiper assembly.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
