Description

Technical Field

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

[0002] The existing side-insertion wiper arm has a problem of thick retaining wall, which leads to the risk of collision between the wiper system and the vehicle's A-pillar. In addition, the existing side-insertion wiper arm cannot prevent errors, that is, it can be rotated backward to the retaining wall area to complete the installation, or it can be rotated forward to the non-retaining wall area to complete the installation. If it is rotated forward to complete the installation, the wiper blade will fall off the wiper arm and cause failure. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an improved connection structure of a side-insertion scraper arm with a thinner thickness and an anti-error function in view of the above-mentioned shortcomings of the existing side-insertion scraper arm.

[0004] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0005] An improved connection structure for a side-inserted scraper arm comprises a scraper blade, a connecting member connected to the scraper blade, and a scraper arm, wherein the connecting member has a windward side and a leeward side, the windward side is an inclined surface, and a rotating shaft hole is provided on the leeward side. The invention is characterized in that the invention further comprises a sheet metal part, a rotating shaft is provided on the sheet metal part, and the rotating shaft is inserted into the rotating shaft hole; the scraper arm is inserted into the sheet metal part.

[0006] In a preferred embodiment of the utility model, a retaining wall is provided on the leeward side of the connecting member, and the sheet metal member interferes with the retaining wall to prevent the scraper arm from excessively rotating in the first direction, thereby achieving error prevention.

[0007] In a preferred embodiment of the utility model, an extension section is provided at one end of the sheet metal part away from the scraper arm, and an open groove is provided between the retaining wall and the leeward side of the connecting member. When the sheet metal part is rotated to a certain angle, the extension section is inserted into the open groove to prevent the sheet metal part from excessively rotating in the second direction, thereby preventing the scraper arm from detaching from the connecting member in the direction of the rotating shaft.

[0008] In a preferred embodiment of the present invention, the scraper arm has an insertion portion with a thickness less than that of the remaining portion, the insertion portion is inserted into the sheet metal component, and the sheet metal component is also thinner than the remaining portion of the scraper arm except the insertion portion.

[0009] Due to the adoption of the above technical solution, the scraper arm of the utility model has an insertion portion with a thickness less than the thickness of the rest of the portion, the insertion portion is inserted into the sheet metal part, and the sheet metal part is also thinner than the thickness of the rest of the scraper arm except the insertion portion, thus reducing the thickness of the entire side-inserted scraper arm, avoiding the risk of collision between the wiper system and the A-pillar of the vehicle, and in addition, an extension section is provided at one end of the sheet metal part away from the scraper arm, and an open groove is provided between the retaining wall and the leeward side of the connecting part, when the sheet metal part is rotated to an angle, the extension section is inserted into the open groove, preventing the sheet metal part from excessively rotating in the second direction, and preventing the scraper arm from detaching from the connecting part in the direction of the rotating shaft. In addition, the sheet metal part cooperates with the retaining wall to prevent the scraper arm from excessively rotating in the first direction, thereby achieving error prevention.

[0016] The present invention is further described below in conjunction with the accompanying drawings and specific implementations.

[0017] See also Figures 1 to 4 The figure shows an improved connection structure of a side-inserted scraper arm, comprising a scraper blade 10, a connecting member 20 connected to the scraper blade 10, and a scraper arm 30. The connecting member 20 has a windward side 21 and a leeward side 22. The windward side 21 is an inclined surface, and a rotating shaft hole 22a is provided on the leeward side 22.

[0018] The characteristics of the utility model are: it also includes a sheet metal part 40, on which a rotating shaft 41 is arranged, and the rotating shaft 41 is inserted into the rotating shaft hole 22a; a slot 42 is arranged on the sheet metal part 40, and the wiper arm 30 has an insertion part 31 with a thickness less than the thickness of the remaining parts, and the insertion part 31 is inserted into the slot 42 of the sheet metal part 40. The sheet metal part 40 is also thinner than the thickness of the remaining parts of the wiper arm 30 except the insertion part 31, thereby reducing the thickness of the entire side-insertion wiper arm and avoiding the risk of collision between the wiper system and the A-pillar of the vehicle.

[0019] A retaining wall 50 is disposed on the leeward side 22 of the connecting member 20 , an open slot 51 is disposed between the retaining wall 50 and the leeward side 22 of the connecting member 20 , and an extension section 43 is disposed at one end of the sheet metal member 40 away from the scraper arm 30 .

[0020] See especially Figure 5 When the sheet metal part 40 rotates to a certain angle, the extension section 43 is inserted into the opening groove 51 to prevent the sheet metal part 40 from excessively rotating in the second direction, and also prevent the scraper arm 30 from escaping from the connecting member 20 in the direction of the rotating shaft 41 .

[0021] See also Figure 6 When the scraper arm 30 rotates an angle toward the first direction, the sheet metal part 40 interferes with the retaining wall 50 to prevent the scraper arm 30 from excessively rotating toward the first direction, thereby achieving error prevention.
