Detailed Description

Referring to fig. 1 to 3, a wiper assembly 100 according to an embodiment of the present application includes a wiper arm 10. The wiper arm 10 includes a joint 1 and an arm portion 2. The joint 1 has a mechanism for detachably connecting the wiper blade 4. The arm 2 extends between the joint 1 and a pivot (not shown) of the drive mechanism, the arm 2 being elongate as a whole, the arm 2 extending in a longitudinal direction L passing through two points of the joint 1 and the pivot, although the arm 2 may be deformed differently due to different requirements. One of the opposite ends of the arm 2 in the longitudinal direction L is fixed to the joint 1, and the other end is fixed to the pivot. During pivoting, the wiper arm 10 carries the wiper blade 4 mounted on the joint 1 in a wiping movement in the wiping direction W. Although the wiper arm 10 is circular in the wiping direction W, the wiping direction W is perpendicular to the longitudinal direction L at a local position on the wiper arm 10.

A connecting body is provided near the joint 1. For example, the connecting body comprises a tab 3 formed integrally with the joint 1. The connecting body is connected to the nozzle member 8 in the connecting direction a. The nozzle member 8 is fixed to the connecting body in a detachable snap-fit manner. For example, the nozzle member 8 includes a fixing portion 84, the fixing portion 84 having a receiving space for receiving the projecting piece 3, the projecting piece 3 being inserted into the fixing portion 84 in the connecting direction a. A notch is provided in the projecting piece 3, and a locking body (not shown) is provided at a position corresponding to the notch in the housing space of the fixing portion 84, and the locking body is locked in the notch to fix the projecting piece 3 to the fixing portion 84.
