Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is provided to a windshield and is housed in a recess formed at the edge of a vehicle body panel and the lower end of the windshield. This article relates to the structure of automobile wipers.

(Prior Art) Wipers installed on the front windshield of automobiles are often attached to the outer surface of the cowl panel arranged between the front windshield and the hood panel, but they are not fully equipped. When a shield type is used, when not in use, it is stored in a recess formed between the rear end of the hood panel and the lower end of the front windshield. When wipers are equipped in this fully concealed manner, their presence is recognized when the front windshield side is seen from the front side of the vehicle in which they are installed, even when they are not in use. This will help reduce visual nuisance on the exterior of the vehicle.

However, in cars equipped with fully concealed wipers, the wipers must move from the lower part of the front windshield to the rear end of the hood panel as required for movement when the wipers operate. A gap is formed, which has a predetermined width and extends in the vehicle width direction along the lower part of the front windshield, and serves as the opening of the wiper storage recess. This will impair the appearance of the car, especially when looking at the front side of the car from the front windshield side, and will also tend to generate relatively loud wind noise when the car is running. There is a problem.

Therefore, in order to solve this problem, for example, in Japanese Utility Model Application Publication No. 158555/1983, full
When a concealed type wiper is installed, an opening/closing cover is provided for the wiper storage recess formed between the rear end of the hood panel and the lower end of the front windshield, and when the wiper is not in operation, 2. Description of the Related Art A wiper storage device has been proposed in which a wiper storage recess in which a wiper is stored is closed by an opening/closing cover. Regarding such a wiper storage device,
The middle part of the opening/closing cover is fixed to one end of a link that is rotatably supported via a pin on a post installed in the middle part of the cowl panel that forms the bottom surface of the wiper storage recess. A predetermined position closer to the hood panel than the middle part is connected to the cowl panel by a spring, and the opening/closing cover is always biased in the direction of opening the wiper storage recess from the perspective of the engagement part with the pillar. be placed in a state When the wiper is in a stopped state and stored in the wiper storage recess, the other end of the link, one end of which is fixed to the middle part of the opening/closing cover, is in contact with the side of the wiper blade. As a result, the opening/closing cover is displaced against the biasing force of the spring, thereby maintaining the opening/closing cover in a state of closing the wiper storage recess.

(Problem to be Solved by the Invention) However, when the conventionally proposed wiper storage device as described above is installed, when the wiper is positioned in the wiper storage recess, the blade portion of the wiper is opened and closed. Since the wiper directly contacts the link connected to the cover and displaces it against the urging force of the spring, the urging force of the spring connected to the opening/closing cover acts on the wiper. As a result, there is a possibility that the original operation of the wiper and the reliability of the opening/closing operation of the opening/closing cover with respect to the wiper storage recess may be impaired.

In view of these points, the present invention allows the arm member equipped with the wiper blade to reliably perform the cleaning operation on the windshield, and when not in operation, the arm member is connected to the edge of the vehicle body panel and the windshield. It can be stored in a recess formed between the lower end portion and the recess can be reliably closed with a cover member that is connected to the vehicle body panel, and the appearance of the portion between the vehicle body panel and the windshield is improved. The purpose of the present invention is to provide an automobile wiper structure that improves the structure of the wiper.

(Means for Solving the Problems) In order to achieve the above-mentioned object, an automobile wiper structure according to the present invention has a wiper blade that comes into contact with the windshield, and the base of the wiper blade is connected to the edge of the vehicle body panel and the windshield. An arm member that is installed in a recess formed between the lower end of the shield and capable of reciprocating movement and that can be stored in the recess, and a cover member that is installed along the longitudinal direction of the arm member. When the arm member is stored in the recess, the cover member forms a surface continuous with the outer surface of the vehicle body panel and closes the recess.

(Function) In the automobile wiper structure according to the present invention configured as described above, the arm member contacts the end edge of the vehicle body panel and the windshield with the wiper blade in contact with the windshield. The windshield is reciprocated along with the cover member about the base attached to the recess formed between the windshield and the lower end of the windshield as a fulcrum, thereby cleaning the windshield.

When the arm member is not in operation, the arm member to which the cover member is attached is stored in the recess formed between the edge of the vehicle body panel and the lower end of the windshield.
The recess in which the arm member is stored is closed by taking a position where the outer surface thereof is continuous with the outer surface of the vehicle body panel.

Therefore, the cleaning operation for the windshield is reliably performed by the reciprocating movement of the arm member, and when the arm member is not in operation, the recess in which the arm member is stored is reliably closed by the cover member, and the vehicle body panel and This will improve the appearance of the area between the windshield and the windshield.
