Description

TECHNICAL FIELD

The present invention relates to car parts, particularly to a windshield wiper.

BACKGROUND OF THE INVENTION

The current windshield wiper usually coma rises a steel blade and a connector which are coupled together by a plurality of arm joints, so the manufacturing cost is high and the connection is not strong enough. Besides, since the assembling process between the adapter and the connector is complex, the combine force is not strong enough. Gradually, it is customary to integrate the adapter onto the connector, which is ultimately designed to include only a wiper with a connector, a retainer, and a retainer cover. Since the connector and wiper blade are connected together, once the connector is damaged, it needs to replace the entire wiper and will increase repairing costs. Accordingly, it urgently needs to devise a windshield wiper with simple and secure structures of the adapter and the connector.

DESCRIPTION OF THE INVENTION

The objection of the present invention is to overcome the deficiency of the complex assembling structures of the connector and the adapter, the all-in-one structure of the adapter and the connector, and the fragile connector by providing a windshield wiper with simple and secure structure of the connector and the adapter.

In order to solve the above-mentioned problems and achieve the objective of the present invention, the technical scheme is to provide a windshield wiper comprising: a connector (1), an adapter (2), a steel blade (3), a rubber blade (4), a retainer (5), a retainer cover (6), and a sleeve (7); the connector (1) having a third slot (105) disposed at a bottom thereof and a spring plate (102) disposed at a top thereof; the steel blade (3) having holes (301) disposed thereon; the steel blade (3) passing through the third slot (105), so that the steel blade (3) is coupled with the third slot (105), and the spring plate (102) is coupled with the holes (301); the steel blade (3) being fixed with the sleeve (7); the sleeve (7) including a second slot (702), and the connector (1) including, a fourth slot (107) disposed at a bottom thereof; the second slot (702) being aligned with the fourth slot (107); the rubber blade (4) being passed through the second slot (702) and the fourth slot (107), and fixed on the connector (1) and the sleeve (7); the rubber blade (4) being coupled with the fourth slot (107); the connector (1) having hinge seats (101), and the adapter (2) having hinge shafts (201) disposed at both sides thereof; one end of the adapter (2) being hingedly connected to the hinge seats (101) by the hinge shafts (201).

More particularly, wherein the adapter (2) comprises a ball-shaped convex point (203) disposed at the other end thereof, and the connector (1) comprises a ball-shaped concave point (106) disposed at an inner wall thereof; the convex point (203) is matched with the concave point (106).

More particularly, wherein the adapter (2) comprises first hooks (202) disposed at the both sides thereof, and the connector (1) comprises second hooks (104) disposed, at the inner wall thereof, the first hooks (202) are coupled with the second hooks (104).

More particularly, wherein the adapter (2) comprises a locating part (204) disposed at a bottom side thereof, and the connector (1) comprises an opening (103) disposed thereon, the locating part (204) is matched with the opening (103).

More particularly, wherein the rubber blade (4) comprises a rib (401), which is connected to the second slot (702).

Compared with the existing technology, the functions and effects of the present invention are described below:

The windshield wiper of the present invention comprises a plurality of slots disposed on different components that is configured to connect between the steel blade and the connector, and the rubber blade and the sleeve. Besides, the windshield wiper further comprises the spring plate and the hole to increase assembling force between the steel plate and the connector; on the other hand, the connector and the adapter have multiple engaging components, so that the connector can combine together with the adapter by snap-fit connection. Therefore, the windshield wiper of the present invention has simple structure and secure assembly, not only reducing the production cost, but also easing maintenance.
