AI Technical Summary
The existing side-plugged scraper arms cannot change the windward surface of the connector to an inclined type, resulting in insufficient down pressure of the scraper under high-speed airflow, which cannot effectively improve the high-speed performance of the scraper.
One end of the scraper arm is inserted from the leeward side of the connector. By setting a shaft hole, an L-shaped retaining wall and an opening groove on the leeward side, the inclined design of the windward side is realized to ensure that the scraper arm is firmly connected.
It effectively solves the problem of inclined design on the windward surface, improves the downforce of the blade under high-speed airflow, and improves the high-speed performance of the blade.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of windshield wipers, in particular to a side-insertion type wiper arm connection 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 connector 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. The existing side-inserted scraper arms on the market are all inserted from the windward surface of the scraper blade, and an auxiliary L-shaped hook is required to help the scraper arm hook the scraper blade to prevent the scraper blade from falling out of the scraper arm. This structure cannot realize the change of the windward surface into an inclined type. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a side-insertion scraper arm connection structure which can change the windward surface of the connecting part of the side-insertion scraper arm into an inclined type in view of the problem that the existing side-insertion scraper arm cannot change the windward surface of the connecting part into an inclined type.
[0004] The technical problem to be solved by the utility model can be achieved through the following technical solutions:
[0005] A side-insertion scraper arm connection structure comprises a scraper blade, a connector and a scraper arm, wherein the scraper blade is mounted on the connector, and the connector has a windward surface and a leeward surface. The invention is characterized in that one end of the scraper arm is inserted from the leeward surface of the connector into the leeward surface of the connector; and the windward surface is inclined.
[0006] In a preferred embodiment of the utility model, a rotating shaft hole is provided on the leeward side of the connecting member, and a rotating shaft is provided at one end of the scraper arm, and the rotating shaft is inserted into the rotating shaft hole.
[0007] In a preferred embodiment of the present invention, an L-shaped retaining wall is provided on the leeward side of the connecting member, and an open groove is provided between the L-shaped retaining wall and the leeward side of the connecting member.
[0008] Due to the adoption of the above technical solution, the utility model inserts one end of the scraper arm into the connecting member from the leeward side of the connecting member, thereby solving the problem that the windward surface of the connecting member can be made inclined.

[0014] The present invention is further described below in conjunction with the accompanying drawings and specific implementations.
[0015] See also Figures 1 to 5 A side-insertion scraper arm connection structure shown in the figure includes a scraper blade 10, a connecting member 20 and a scraper arm 30. The scraper blade 10 is installed on the connecting member 20, and the connecting member 20 has a windward surface 21 and a leeward surface 22.
[0016] The utility model is characterized in that one end of the scraper arm 30 is inserted into the leeward surface 2 of the connecting member 20 from the leeward surface 2 of the connecting member 20; the windward surface 21 is inclined, specifically:
[0017] A rotating shaft hole 22 a is provided on the leeward side 22 of the connecting member 20 , and a rotating shaft 31 is provided at one end of the scraper arm 30 , and the rotating shaft 31 is inserted into the rotating shaft hole 22 a .
[0018] An L-shaped retaining wall 40 is disposed on the leeward side of the connecting member 20 , and an open slot 41 is disposed between the L-shaped retaining wall 40 and the leeward side 22 of the connecting member 20 .
[0019] See especially Figure 5 , rotate the scraper arm 30 downward to the L-shaped retaining wall 40 area and make the scraper arm 30 snap into the opening groove 41, the L-shaped retaining wall 40 cooperates with the scraper arm 30 to prevent the scraper arm 30 from escaping from the connecting member 20 in a direction parallel to the rotating shaft 31.
