Abstract

An exemplary embodiment of the present invention includes a wiper blade assembly structure which has a space unit formed in a certain area of a support frame, to which a main arm of the wiper is coupled, and allows a replaceable adaptor to be detachably attached to the space unit to thereby enable various types of main arms to be coupled to a single support frame together with the replaceable adaptor.

Claims

1. A wiper blade assembly structure comprising:

a main arm which operates by a driving force supplied by a wiper motor;

a support frame which is connected to the main arm and receives the driving force from the main arm and has a space unit formed in a certain size in an upper central part thereof and a lower coupling member formed in the space unit to be coupled to a replaceable adaptor;

a replaceable adaptor which is detachably attached to the space unit of the support frame by a fixing means using a fixing pin and couples the main arm to the support frame;

a blade fixer which is coupled to a lower part of the support frame; and

a blade which is coupled to the blade fixer;

wherein the replaceable adaptor includes a coupling part formed in a central part thereof to be detachably coupled to a front end coupling part of the main arm, and an upper coupling member formed in a lower part thereof corresponding to the lower coupling member of the support frame, and wherein the replaceable adapter is of a size to be inserted into an inside of the space unit of the support frame.

2. The wiper blade assembly structure according to claim 1, wherein the lower coupling member of the support frame comprises at least one fixing pin to fix the replaceable adaptor in a vertical direction, and a hook member to fix the replaceable adaptor to the space unit of the support frame.

3. The wiper blade assembly structure according to claim 1, wherein the replaceable adaptor is replaced by other types of replaceable adaptors to be coupled to each main arm, depending on the type of the main arm.

4. The wiper blade assembly structure according to claim 1, wherein an insert reinforcing frame is installed in a internal lower side of the part where the replaceable adaptor of the support frame is installed.

5. The wiper blade assembly structure according to claim 1, wherein the insert reinforcing frame comprises a steel material, and is formed in a longer length than the space unit of the support frame.
