A wiper connection structure, comprising a connection body and an upper cover. The connection body is mounted on a wiper blade; an accommodating cavity is formed on the connection body; the accommodating cavity is opened on an upper surface and a side vertical surface of the connection body respectively to correspondingly form an upper opening and an inlet for the head of a wiper to insert into the accommodating cavity; the upper cover is hingedly connected to the upper opening, and the upper cover can sealably close and open the upper opening; in addition, at least one of the accommodating cavity and the upper cover is provided with a limiting member capable of stopping and limiting the head of the wiper, so as to ensure that the head of the wiper does not fall off from the accommodating cavity.

The invention is based on a wiper blade adapter, in particular for a motor vehicle wiper device, with a coupling unit (10a; 10b). It is proposed that the coupling unit (10a; 10b) has at least one first and one second coupling element (12a, 14a; 12b, 14b), which coupling elements are provided for coupling at least two different types of wiper arm adapters (100a, 110a, 120a; 130b, 140b).

A wiper adapter detachably coupled between a wiper arm and a wiper having a pivot shaft, the adapter comprises a first coupling element and a second coupling element. The first coupling element has a shaft cavity provided with a notch that is in communication with the shaft cavity; the pivot shaft can be assembled into the shaft cavity radially through the notch and can pivotably fit in the shaft cavity. The second coupling element can snap to the pivot shaft so as to prevent the pivot shaft from leaving the shaft cavity through the notch.

The invention relates to a wiper device (100) for the cleaning of vehicle windows (1), with a wiper blade (10) fastened exchangeably on a wiper arm (2), which wiper blade is connected with the wiper arm (2) via a wiper blade adapter (11), wherein in the fastening region to the wiper blade (10) the wiper arm (2) has a substantially U-shaped cross section, which embraces the wiper blade adapter (11), wherein on the wiper arm (2) in the connecting region a securing element (27) for the wiper blade adapter (11) is provided which is movably arranged at least in the longitudinal direction of the wiper arm (2) and which partially overlaps the wiper arm (2) in the connecting region and has a substantially U-shaped cross section with holding sections (46, 47) projecting inwards in the direction towards the wiper blade adapter (11). It is provided according to the invention that, in addition to its longitudinal displaceability, the securing element (27) is arranged pivotably on the wiper arm (2).

A wiper connector for a vehicle may be provided which connects a wiper arm to a wiper blade 10 and includes: a body 320 including a pair of elastic moving pieces 362 which is formed on one end thereof and faces each other, and one or more coupling parts 330 and 340 which are formed on both sides thereof and by which the wiper arm is caught; and a cover 310 movable to a fixing position for fixing the wiper arm which is caught by the body 320 and to a release position for releasing the fixed wiper arm. The pair of the elastic moving pieces 362 elastically restrains the movement of the cover 310 at the fixing position and allows the cover 310 to move to the release position when a releasing force for removing the elastic restraint is applied to the elastic moving piece 362.

A wiper adapter includes a base and a shielding cover. The base has a top wall, a pair of side walls, and a pair of bottom walls. Two sides of the top wall respectively include a limiting wall extending upward. A width of the lateral L-shaped structure along a transverse direction is smaller than a width of one of the bottom walls along the transverse direction. The at least one lateral L-shaped structure is configured to stop a displacement of a wiper arm. Each bottom wall has at least one lower L-shaped structure that is configured to stop a displacement of another wiper arm. A receiving slot is formed between the shielding cover and the base, and is configured to receive yet another wiper arm. The shielding cover is connected to a front end of the pair of side walls to stop a displacement of the wiper arm.
