Description

Technical Field

[0001] The utility model relates to the technical field of windshield wipers, in particular to an improved structure of a high-speed wiper arm. Background Art

[0002] In order to improve the high-speed performance of the scraper blade, some manufacturers on the market have changed the scraper blade connecting piece into an inclined surface, that is, the windward surface is changed into an inclined surface, which can increase the downward pressure of the high-speed airflow on the scraper blade.

[0003] Most manufacturers on the market insert the scraper arm into the scraper blade connector. Due to the limited space on the inclined surface, the scraper arm insertion end is usually cut very narrow, resulting in a general reduction in the stiffness of the scraper arm. At the same time, since the scraper arm cooperates with the scraper blade connector, and the scraper blade connector cooperates with the scraper blade fixing seat, the accumulated gap between the two cooperations usually leads to an excessive gap between the scraper blade and the scraper arm, resulting in a swinging phenomenon. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an improved structure of a high-speed scraper arm for improving the anti-escape performance of products in view of the deficiencies in the above-mentioned prior art.

[0005] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0006] A high-speed scraper arm improved structure, comprising a scraper blade, a scraper blade fixing seat for fixing the scraper blade, a scraper arm with one end inserted into the scraper blade fixing seat, and an outer cover attached to the scraper arm and inserted into the scraper blade fixing seat, wherein the windward surface of the outer cover is an inclined surface, and shafts are arranged on a pair of side surfaces of the scraper blade fixing seat. It is characterized in that the end of the scraper arm inserted into the scraper blade fixing seat is U-shaped, and a first open groove is arranged on each side wall of the U-shape, and the first open groove is sleeved on the shaft, so that the scraper arm is hinged on the scraper blade fixing seat.

[0007] In a preferred embodiment of the present invention, a protrusion is provided on at least one side surface of the scraper blade fixing seat, and a second opening groove is provided on the side wall of the U-shape corresponding to the protrusion. After the scraper arm is installed in place, the protrusion is embedded in the second opening groove to prevent the shaft from falling out of the first opening groove, thereby preventing the scraper blade fixing seat from falling out of the scraper arm.

[0008] In a preferred embodiment of the present invention, the second opening groove is in a step-shaped shape, so that the protrusion can be easily embedded in the second opening groove.

[0009] Due to the adoption of the above technical solution, the utility model designs the end of the scraper arm inserted between the scraper blade fixing seat and the scraper blade connecting member into a U shape, thereby improving the strength of the scraper arm insertion end, and also making the scraper arm insertion end wrap around the scraper blade fixing seat, thereby reducing the gap between the two. In addition, through the cooperation between the shaft and the first opening groove, the scraper arm is inserted between the scraper blade fixing seat and the scraper blade connecting member, and through the design of the protrusion and the second opening groove, the shaft is prevented from slipping out of the first opening groove, thereby preventing the scraper blade fixing seat from slipping out of the scraper arm. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the wiper structure of the utility model.

[0011] Figure 2 It is a structural schematic diagram of the insertion end of the scraper arm of the utility model.

[0012] Figure 3 It is a schematic diagram of the scraper arm of the utility model being installed on the scraper blade fixing seat. DETAILED DESCRIPTION

[0013] The present invention is further described below in conjunction with the accompanying drawings and specific implementations.

[0014] See also Figures 1 to 3 An improved structure of a high-speed scraper arm as shown in the figure includes a scraper blade 10, a scraper blade fixing seat 20 for fixing the scraper blade 10, a scraper arm 40 with one end inserted into the scraper blade fixing seat 20, and an outer cover 30 attached to the scraper arm inserted into the scraper blade fixing seat 20, the windward surface 31 of the outer cover 30 is an inclined surface, and a shaft 22 is provided on a pair of side surfaces 21 of the scraper blade fixing seat 20.

[0015] The utility model is characterized in that one end 41 of the scraper arm 40 inserted into the scraper blade fixing seat 20 is U-shaped, and an opening groove 43 (the aforementioned first opening groove) is provided on each side wall 42 of the U-shape, and the opening groove 43 is sleeved on the shaft 22, so that the scraper arm 40 is hinged on the scraper blade fixing seat 20 and can rotate around the shaft 22.

[0016] A protrusion 23 is provided on a side surface 21 of the scraper fixing seat 20 , and an opening groove 44 (the aforementioned second opening groove) is provided on a U-shaped side wall 42 corresponding to the protrusion 23 . The opening groove 44 is stepped to facilitate the protrusion 23 to be embedded in the opening groove 44 .

[0017] After the scraper arm 40 is installed in place, the protrusion 23 is embedded in the opening groove 44 to prevent the shaft 22 from slipping out of the opening groove 43 , thereby preventing the scraper blade fixing seat 20 from slipping out of the scraper arm 40 .
