Abstract

The invention provides a wiper blade, a wiper and a wiper blade assembly method. The wiper blade comprises a supporting assembly and a connector, the supporting assembly comprises a first elastic element and a second elastic element which is arranged to be spaced apart from the first elastic element in parallel, and a gap is formed between the first elastic element and the second elastic element;the connector is configured to be formed at least partially of a meltable material and attached to the support assembly by welding; wherein, at a position where the support assembly is connected to the connector, at least one recess is provided at a side of at least one of the first elastic element and the second elastic element opposite to the gap, the recess being configured to receive at leasta portion of a material generated by melting the connector during welding. The wiper blade, the wiper and the wiper blade assembling method have the advantages of being simple, reliable, easy to manufacture, convenient to install and the like, the situation that welding materials are gathered on the outer surface of a product can be reduced, and the performance of welding connection is improved.

Description

technical field [0001] The present application relates to the field of wiper constructions. More particularly, the present application relates to a wiper blade intended to improve the connection performance and appearance of wiper parts. The present application also relates to a wiper including the above-mentioned wiper blade, and a method for assembling the wiper blade. Background technique [0002] A wiper usually includes a wiper arm and a wiper blade driven by the wiper arm. A typical wiper blade includes a support assembly and a connector. The wiper arm is coupled with the support assembly through a connector. The support assembly has a curved shape that fits the outer surface of the vehicle glazing, and is generally configured elastically. To ensure a reliable connection between the support assembly and the connector, the connector is typically formed from a weldable and meltable material and welded to the support assembly by melting at least a portion of the conne...
