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 outer cover. 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 connection 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 rod insertion end is usually cut very narrow, resulting in generally low scraper arm stiffness. At the same time, the scraper arm cooperates with the connector, and the connector cooperates with the scraper blade fixing seat. The accumulated gap between the two cooperations usually leads to excessive clearance between the scraper blade and the scraper arm, resulting in swinging, and there is also the risk of the scraper arm and the scraper blade coming out. In addition, the outer cover of the existing high-speed scraper arm structure cannot quickly determine whether the scraper arm is installed in place. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide an improved structure of a high-speed scraper arm outer cover in view of the above technical deficiencies existing in the existing high-speed scraper arm, so as to solve the above deficiencies existing in the existing technology.

[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 cover 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 a cover installed on the scraper arm; the cover has a windward side and a leeward side, and an axis is arranged on two opposite side surfaces of the scraper blade fixing seat; the scraper arm is U-shaped at one end inserted into the scraper blade fixing seat, and a snap groove is provided on two opposite side walls of the U-shape, and the snap groove is sleeved on the shaft so that the scraper arm is hinged on the scraper blade fixing seat, and it is characterized in that an open groove is provided on the leeward side of the outer cover, and the open groove cooperates with the shaft on the fixing seat, and the open groove is used to judge whether the shaft is inserted into the snap groove.

[0007] In a preferred embodiment of the utility model, a vertical wall extending along the length direction of the scraper blade is provided in the outer cover, a groove is provided on one side wall of the U-shape adjacent to the vertical wall, a protrusion is provided on the vertical wall, and the protrusion is embedded in the groove.

[0008] Due to the adoption of the above technical solution, the utility model provides an open slot on the leeward side of the outer cover, and the open slot is sleeved on the shaft of the scraper blade fixing seat to observe whether the buckle slot on the scraper arm is installed in place with the shaft.

[0011] Figure 3 for Figure 1 A-direction view. DETAILED DESCRIPTION

[0012] The present invention is further described below in conjunction with the accompanying drawings and specific implementations.

[0013] See also Figures 1 to 3 The figure shows an improved structure of a high-speed scraper arm cover, which 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 a cover 30 installed on the scraper blade fixing seat 20.

[0014] The outer cover 30 has a windward side 31 and a leeward side 32 , and a shaft 22 is disposed on two opposite sides of the scraper fixing seat 20 .

[0015] One end 41 of the scraper arm 40 inserted into the scraper blade fixing seat 20 is U-shaped, and a buckle groove 43 is formed on two opposite side walls 42 of the U-shape. The buckle groove 43 is sleeved on the shaft 22 so that the scraper arm 40 is hinged on the scraper blade fixing seat 20.

[0016] A vertical wall 33 extending along the length direction of the scraper blade 10 is provided in the outer cover 30. The vertical wall 33 and the leeward side 32 of the outer cover 30 form a U-shape that matches one end of the scraper arm 40 inserted into the scraper blade fixing seat 20, and wraps the U-shape on the scraper arm 40.

[0017] An opening slot 34 matched with the buckle slot 42 is provided on the leeward side 32 of the outer cover 30 . The opening slot 34 is sleeved on the shaft 22 to observe whether the buckle slot 42 on the scraper arm 40 is installed in place with the shaft 22 .

[0018] A groove 44 is provided on one side wall 42 of the U-shaped structure adjacent to the vertical wall 33 , and a protrusion 35 is provided on the vertical wall 33 . The protrusion 35 is embedded in the groove 44 to limit the scraper arm 40 and the outer cover 30 from coming out in the length direction of the scraper blade 10 .
