Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concealed wiper storage device.

As is well known, in a concealed wiper storage device in which wipers are stored in an opening formed between the rear end of a car's hood and the windshield, when the car is running, airflow is caught in the opening and generates noise. to occur, and during snowfall,
In some wiper wipers, the opening can be opened and closed with a wiper cover to prevent snow from entering the opening and causing malfunction of the wiper, as well as from problems with appearance.

However, the wiper cover must be opened and closed within a narrow space between the bonnet and the windshield, and it has been difficult to provide an opening and closing mechanism that can perform reliable and stable opening and closing operations.

Therefore, the present invention is designed to
The purpose of the present invention is to provide a concealed wiper storage device capable of opening and closing a wiper cover in a reliable and stable manner. Therefore, the feature is that the front wiper is provided in the opening formed between the rear edge of the bonnet and the windshield, and a concealed wiper storage device is provided with a wiper cover that allows the opening to be opened and closed. A pair of guide rails are provided in parallel along the front-rear direction on both the left and right sides of the opening, a slider moved by a drive device is slidably fitted to the rails, and a pair of front and rear cam followers are fitted to the slider. On the other hand, a cam is provided on the back side of the wiper cover, and the cam is provided with a pair of elongated cam grooves in the front and back direction and having a stroke difference between the top and bottom, and the cam groove and the cam follower are connected to each other. The cam lowering stopper, which is slidably fitted and engages with the cam when the slider moves forward after the wiper cover closes the opening, prevents the cam from moving forward but allows it to move downward, is attached to the rail. and at the lower end of the stopper,
When the cam descends a predetermined amount, the engagement is released, and a notch is provided that allows the cam and slider to move forward together. The rail is provided with a cam lift stopper that engages with the cam and prevents the cam from moving backwards but allows it to move upwards after allowing a certain amount of the cam and slider to move together backwards.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

In Figure 1, 1 is the bonnet of a passenger car, 2
3 is a windshield, 3 is a front wiper, and 4 is a concealed wiper storage device in which the front wiper 3 can be stored.

Details of the concealed wiper storage device 4 are shown in FIGS. 2 and 3.

In the figure, an opening 5 is provided between the rear end edge of the bonnet 1 and the windshield 2, and a front wiper 3 is housed within the opening 5 so as to be movable forward and backward. The opening 5 is covered by a wiper cover 6 so as to be openable and closable.

A pair of left and right guide rails 8 are laid in parallel along the front-rear direction on the upper surface of the cowl box 7 below the rear end of the bonnet 1. A slider 9 is slidably fitted into the guide rail 8. The slider 9 is provided with a pair of guide rollers 10 and 11 at the front and rear, and a pair at the top and bottom. are doing. Furthermore, a pair of front and rear cam followers 13 are provided coaxially with the upper roller 10.
A cable holder 14 is fixed to the slider 9, and the cable holder 14 is attached to the guide rail 8.
The push-pull wire 16 is connected to the guide groove 15 of the push-pull wire 16 . This push-pull wire 16 is moved in the front-rear direction by a drive device (not shown).

On the other hand, the wiper cover 6 is composed of a panel outer 17 that covers the opening 5 and a pair of left and right panel inners 18 fixed to the lower surface of the outer panel 17.
The cam 20 is fixed via the cam 20. A guide roller 21 is provided protruding from the guide bracket 19. The cam 20 is provided with a pair of same-shaped elongated cam grooves 22 at the front and rear. A parallel portion 23 that is parallel to the guide rail 8 is provided at the end.

The cam follower 13 of the slider 9 is movably fitted into the cam groove 22.

A slider front end stopper 24 and a slider rear end stopper 25 are fixed to the front and rear ends of the guide rail 8 to restrict the movement of the slider 9 in the front and rear directions.

Furthermore, the guide rail 8 includes a cam raising stopper 26 that comes into contact with the rear end of the cam 20 to restrict the backward movement of the cam 20, and a cam lowering stopper that engages with the guide roller 21 and restricts the forward movement of the cam 20. 27 are provided.

In addition, the slider rear end stopper 25, cam up stopper 26, and cam down stopper 27
are integrally provided on one set plate 28, and the set plate 28 is fixed to the guide rail 8. And the cam lowering stopper 27
A notch 29 is provided in the set plate 28 corresponding to the lower end of the guide rail 8. It is configured to be movable.

Next, the effects of the embodiment of the present invention will be explained.

As shown in FIG. 2, when the panel outer 17 of the wiper cover 6 closes the opening 5, the slider 9 is in the rear position and engaged with the slider rear end stopper 25.
The cam follower 13 of the cam groove 22 of the cam 20
It fits into the parallel portion 23 at the rear end. The rear end of the cam 20 and the cam lift stopper 26 are engaged. At this time, the guide roller 21 is also engaged with the front surface of the cam lowering stopper 27.

In the closed state, the pair of front and rear cam followers 13 are located in the parallel portion 23 of the cam groove 22 and hold the cam 20, so the wiper cover 6 can stably close the opening 5. Vibration is prevented.

Next, to open the opening 5, the push-pull wire 16 is moved forward by a drive device (not shown). This forward movement causes the slider 9 to move forward via the cable holder 14. At this time, the cam 20 cannot move forward because the guide roller 21 is engaged with the cam lowering stopper 27. Therefore, the cam follower 13 provided on the slider 9 moves within the cam groove 22. Due to this movement of the cam follower 13, the cam 20 is lowered, and accordingly, the wiper cover 6 is lowered at that position as shown by the imaginary line in FIG. secure.

As the cam 20 descends, the guide roller 21
is the notch 29 at the lower end of the cam lowering stopper 27.
and moves to the guide groove 12 of the guide rail 8. This releases the restriction on the forward movement of the guide roller 21. In this state, the cam follower 13 is located at the front end of the cam groove 22. Thereafter, as the slider 9 moves forward, the cam 20 also moves, the wiper cover 6 is housed under the bonnet 1, and the opening 5 is opened.

Next, to close the slider 9 from the open state, the slider 9 is moved rearward via the push-pull wire 16. As a result, relative movement is likely to occur between the cam groove 22 and the cam follower 13.
That is, the cam follower 13 attempts to move relatively to the rear end of the cam groove 22 and attempts to raise the cam 20. However, since the guide roller 21 is fitted into the guide groove 12, the cam 20 does not rise, and therefore the cam follower 13 is inserted into the cam groove 12.
The cam 20 is moved rearward while remaining located at the front end of the cam 2.

The rear end of the cam 20 comes into contact with the cam lift stopper 26, and the rearward movement of the cam 20 is restricted.
At this time, a notch 29 is formed above the guide roller 21.
By further moving the slider 9 backward, the cam follower 13 moves in the cam groove 22, and the guide roller 21 moves into the notch 2.
9, the cam 20 rises. The wiper cover 6 then closes the opening 5 and returns to the state shown in FIG. 2.

Note that the present invention is not limited to the above embodiments.

According to the present invention, the structure is simple, stable, and reliable opening/closing operations can be performed.
