Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or position relationship shown in the drawings, and are only for convenience of description and simplification of the present invention, but do not indicate or imply that the device or element of the present invention must have a specific orientation, and thus, should not be construed as limiting the present invention.

Examples

For convenience of description, in the present application, the direction of each part toward the center of the left wiper blade and the right wiper blade is defined as front, and the opposite direction is defined as back; the direction of each component toward the vehicle glass is defined as down, and the opposite direction is up.

Referring to fig. 1, the present invention discloses a novel wiper connector, which includes an upper seat 1 and a lower seat 2.

The upper seat 1 is used for being matched and connected with a first rocker arm 4 or a second rocker arm 5. The elastic clamping device comprises an outer end part 11 and a plug-in part 12 which is backwards contracted and extended from the outer end part 11, wherein two sides of the outer end part 11 are inwards concave to form an open slot 111, the open slot 111 faces backwards, an elastic clamping shaft 112 is arranged in the open slot 111, an elastic positioning block 121 is arranged on the top surface of the plug-in part 12, and two sides of the plug-in part 12 are provided with hinge holes 122.

The upper part of the lower seat 2 is provided with a hinge seat 21, two sides of the hinge seat 21 are provided with hinge shafts 211, and the hinge shafts 211 are clamped into the hinge holes 122, so that the lower seat 2 is hinged to the upper seat 1. The lower part of the lower seat 2 has a wiper interface 22 for engaging with the engaging part 3 of the wiper sheath.

Referring to fig. 2, 3 and 4, specifically, at least a pair of square teeth 31 are disposed on two side edges of the clamping portion 3, at least a pair of L-shaped blocks 222 are disposed on two sides of an inner wall of the wiper interface 22, and the L-shaped blocks 222 and the inner wall step portion 221 of the wiper interface 22 form a U-shaped bayonet 223 together. Therefore, the non-square tooth area of the clamping portion 3 is aligned with the U-shaped bayonet 223 to be sleeved, and then the square tooth 31 is clamped into the U-shaped bayonet 223 by horizontally pushing towards the bayonet end direction of the U-shaped bayonet 223.
