Windscreen wiper connecting part and windscreen wiper arm matched with the same and assembling method thereof

Abstract

The invention discloses a windscreen wiper connecting part. An elastic structure A (1) is arranged in an inner cavity of a connecting part body (8) and designed into a both-sides-connection structural form or a cantilever structural form, and the elastic structure A (1) is 0.15-0.35 mm higher than the plane of the inner cavity and matched with two outer side faces of the vertical wall in the middle of a metal connector (9); multiple protruding elastic structures B (2) are arranged at the top end of the connecting part body (8), and the elastic structures B (2) are 0.2-0.4mm higher than the plane of an outer cavity and matched with the upper wall of an inner cavity of a windscreen wiper arm (7); two types of buckles which are of buckling structures, namely buckles A (3) and buckles B (4), are symmetrically arranged on the two side faces of the connecting part body (8), wherein the buckles A (3) are semicircular protrusions arranged at the two sides of the head of the connecting part body (8); the buckles B (4) are arranged at the two sides of the tail of the connecting part body (8), and guiding chamfers are formed at the edges of the buckles B (4). A semicircular groove matched with the buckles A (3) in shape is formed in the windscreen wiper arm which is matched with the windscreen wiper connecting part, and the windscreen wiper arm is further provided with a side face groove (6) which is matched with the buckles B (4) in shape. A method for assembling the windscreen wiper connecting part with the windscreen wiper arm is classified into a spinning type and a plug-in type.

Description

technical field [0001] The invention belongs to a vehicle wiper device, in particular to a wiper connector, a matched wiper arm and an assembly method thereof. Background technique [0002] The vehicle wiper device, the wiper blade is connected to the end of the wiper arm, and also includes at least one detachable wiper blade, and the detachment is realized through the connecting device. At present, there are various connection modes between the wiper arm and the wiper blade, which belong to the patents of different companies. There are currently the following issues with connected devices: [0003] 1. With the current connection method, due to the manufacturing process, the gap between the mutual cooperation cannot be completely eliminated, and it is easy to cause obvious shaking of the wiper blade during use, causing customer dissatisfaction. [0004] 2. With the current connection method, the wiper blade may come out of the wiper arm during use. Contents of the invent...
