DETAILED DESCRIPTION

[0027] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figure 1-7 As shown, a novel wiper connection structure comprises an outer cover 1, a connector body 2 and a base 3, wherein the outer cover 1 is arranged on the connector body 2, and the connector body 2 is arranged on the base 3;

[0029] A first limit block 201 is provided at one end of the connector body 2, and a second limit block 202 is provided at the other end thereof; a clearance groove 203 is provided at one end of the first limit block 201, a push block 204 is provided between the first limit block 201 and the clearance groove 203, and a connecting groove 205 is provided on the lower side of the clearance groove 203; a limit installation groove 211 is provided between the connecting groove 205 and the second limit block 202, so as to improve the connection strength and stability of the wiper, while improving the service life of the wiper and extending the scope of application.

[0030] A height limiting platform 206 is disposed at one end of the second limiting block 202 ; a mounting limiting platform 207 is disposed at the lower side of the height limiting platform 206 , and the mounting limiting platform 207 is disposed vertically to the outer wall of the connector body 2 .

[0031] In addition, the installation limit platform 207 has a plurality of anti-slip teeth 208. In the present embodiment, there are three anti-slip teeth 208. A mounting slot 209 is provided on one side of the installation limit platform 207. An anti-swing block 210 is provided on one side of the installation slot 209 to prevent a gap from appearing between the connector body and the wiper arm, causing the wiper to shake during movement, aggravating the deformation of the rubber strip, and shortening the service life of the wiper; and to prevent the connector body 2 and the base 3 from falling off and affecting driving safety.

[0032] Furthermore, the outer cover 1 has two side walls, one end of which is provided with a longitudinal undercut 4, and the other end thereof is provided with a transverse undercut 5; a support rod 6 is provided between the two side walls to improve the connection strength and stability of the two side walls of the outer cover 1.

[0033] In addition, limiting plates 7 are provided on both sides of the base 3 , and a connecting shaft 8 is provided between the limiting plates 7 on both sides, so as to simplify the connection between the connector body 2 and the base 3 .

[0034] Furthermore, a spring clip installation groove 9 is provided on the lower side of the base 3 to facilitate the combined installation of the base 3 and the spring clip.

[0035] In addition, two side walls of the inner cavity of the first limiting block 201 are provided with limiting slots 10 for fixing the outer cover 1 to improve the connection strength of the outer cover 1 .

[0036] Furthermore, the side wall of the connector body 2 is provided with an installation indicator groove 11 to facilitate assembly by employees.

[0037] The connector body 2 is connected and fixed to the wiper arms of different installation structures in different ways:

[0038] like Figure 8 As shown, the mounting hole 13 in the middle of the wiper arm 12 is connected to the second limit block 202, and the distance between the mounting hole 13 in the middle of the wiper arm 12 and one end of the wiper arm 12 is greater than the distance between the push block and the second limit block 202. After the wiper arm 12 and the connector body 2 are installed, the push block 204 is deformed and acts on the wiper arm 12, so as to reduce the installation gap between the wiper arm 12 and the connector body 2, thereby improving the connection strength and stability of the wiper.

[0039] like Fig. 9 As shown, one end of the wiper arm 12 is provided with a mounting end 14, and the mounting end 14 is arranged between the first limit block 201 and the push block 204, and the height limit block 206 is connected to the mounting groove 15 of the wiper arm 12. After the wiper arm 12 and the connector body 2 are installed, the push block 204 is deformed and acts on the connecting end 14 of the wiper arm 12, thereby improving the connection strength and stability of the wiper connecting end 14;

[0040] Avoid the wiper from shaking during operation, which may cause the rubber strip to deform and result in partial failure of the wiper to wipe water during operation. In this case, there is a risk of the connector body and base falling off, affecting driving safety.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
