Description

Technical Field

[0001] The utility model relates to the technical field of windshield wipers, in particular to a high-speed wiper arm outer cover assembly structure. 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, since the scraper arm is matched with the connector, and the connector is matched with the scraper blade fixing seat, the accumulated gap between the two matches usually leads to a large gap between the scraper blade and the scraper arm, resulting in swinging. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a high-speed scraper arm outer cover assembly structure for the above-mentioned technical deficiencies existing in the existing high-speed scraper arm, so as to solve the deficiencies existing in the above-mentioned 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 assembly structure comprises 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 surface and a leeward surface; the scraper arm has a first U-shape at one end inserted into the scraper blade fixing seat, and buckles are provided on the two vertical walls of the first U-shape, and a pair of side surfaces of the scraper blade fixing seat are respectively provided with an axis, and the buckle is hinged on the axis so that the scraper arm is hinged to the scraper blade fixing seat; it is characterized in that a vertical wall is provided in the cover, which forms a second U-shape with the leeward side to buckle the first U-shape to ensure that the cover does not fall off the scraper arm.

[0007] In a preferred embodiment of the utility model, at least one groove is provided on each of the two vertical walls of the first U-shape, and at least one elastic buckle is provided on each of the leeward side and the vertical wall of the outer cover, and the elastic buckle is clamped in the groove.

[0008] Due to the adoption of the above technical solution, the utility model limits the outer cover from withdrawing from the scraper arm in the length direction of the scraper blade by cooperating with each other through the groove arranged on the scraper arm and the elastic buckle arranged on the outer cover.

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

[0014] See Figures 1 to 4 A high-speed scraper arm outer cover assembly structure 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 installed on the scraper arm 40. The outer cover 30 has a windward surface 31 and a leeward surface 32.

[0015] See especially Figure 2 One end 41 of the scraper arm 40 inserted into the scraper blade fixing seat 20 is in a first U-shape, and a buckle 42a, 43a is respectively provided on the two side arms 42, 43 of the first U-shape, and shafts (not shown in the figure) are provided on a pair of side walls of the scraper blade fixing seat 20, and the buckles 42a, 43a are hinged on the corresponding shafts, so that one end of the scraper arm 40 is hinged to the scraper blade fixing seat 20.

[0016] A vertical arm 34 is provided inside the outer cover 30, and a second U-shape is formed between the vertical arm 34 and the leeward side 32 of the outer cover 30. The second U-shape wraps around the first U-shape to ensure that the outer cover 30 does not fall off the scraper arm 40.

[0017] Two grooves 42b, 42c, 43b, 43c (the number of grooves can be one or more) are also respectively provided on the two side arms 42, 43 of the first U shape, the grooves 42b, 42c are located at the front and rear sides of the buckle 42a, and the grooves 43b, 43c are located at the front and rear sides of the buckle 43a.

[0018] Two elastic buckles 32a, 32b, 34a, 34b are respectively provided on the leeward side 32 of the outer cover 30 and the vertical arm 34 (of course, only one elastic buckle 33 can also be provided), and the elastic buckles 32a, 32b, 34a, 34b are respectively clamped in the grooves 42b, 42c, 43b, 43c to limit the outer cover 30 from escaping from the scraper arm 40 along the length direction of the scraper blade 10.
