A movable engagement member 8 provided at the front end of the front side plate 5 is slidably disposed on a guide rail 9. The driving force of the cover opening/closing motor 10 rotates the cam plate l3 via the gears 11l and 12, and the cam plate l3 and the front fIll!
A driving force is transmitted through a link 14 disposed between the movable engaging member 8 and the movable engaging member 8 as it slides on the guide rail 9, thereby being driven to fold and open/close. In such a conventional device, when the wiper switch is operated, the front window wiper 4 is driven, the cover opening/closing motor 10 is operated, the cover member 3 is opened, and the front window wiper 4 is opened from this opening.
The wiper blade 4a moves in and out to wipe the front window glass 2. [Problem M that Seimei tries to solve] However, in such a conventional device, since the cover member 3 is configured to open when the wiper switch is turned on, the cover member 3 If there is snow on the ground, the snow must be removed. In particular, if you notice this while the vehicle is running, you must stop the vehicle and remove the snow from the cover member 3, which is troublesome. [Means for Solving the Problems] The present invention has been made by focusing on the above-mentioned conventional problem, and the front window wiper storage recess is located on the lower edge side of the front window panel approximately in the width direction of the vehicle. A wiper cover is provided at the opening of the wiper storage recess, which is formed over the entire width, and can be opened and closed by driving a cover opening/closing actuator, and when the front window wiper is not in use, the wiper cover closes the opening. developed,
In an automobile front window wiper storage device that opens when in use, a control that applies current to the cover opening/closing actuator for a certain period of time when the ignition switch is turned on to determine whether the cover opening/closing actuator operates normally. The present invention is characterized by an automobile front window wiper storage device having a unit and a warning means for issuing an alarm when the cover opening/closing actuator does not operate normally according to a signal from the control unit. [Function] According to this means, when the ignition switch is turned on, a current flows through the cover opening/closing actuator for a certain period of time, and the control unit determines whether or not the cover opening/closing actuator operates normally. If the actuator does not operate normally, an alarm will be issued by the warning means using a signal from the control unit. Therefore, since the operation of the wiper cover can be confirmed in advance before the vehicle starts running, it is possible to ensure that the wiper cover is in operation before driving, and there is no need to temporarily stop the vehicle while the vehicle is running, as was the case in the past. do not have. [Examples] This invention will be explained below based on Examples. 1 to 5 are diagrams showing one embodiment of the present invention. First, the configuration will be explained. In the figure, reference numeral 21 is the engine hood, and reference numeral 22 is the front window glass. Reference numeral 23 denotes a cowl box, and this cowl box 23 is composed of a cowl top panel 24 and a dash upper panel 25. This cowl top panel 24 is the fourth
As shown in the figure, a storage recess 27 in which the front window wiper 26 is stored is formed by being recessed along the vehicle width direction. Reference numeral 28a in FIGS. 2 and 3 is a wiper blade of the front window wiper 26. The wiper cover 24, which opens and closes the opening 27a of the storage recess 27, is moved by an opening/closing device 2. This opening/closing device 28 is shown in FIGS.
It is configured as shown in the figure. That is, first, the fourth
As shown in the figure, a cover opening/closing actuator 29 and a guide plate 30 extending in the vertical direction are mounted on the cowl top panel 24.
As shown in FIG. 4, a vertical slit 30a extending in the vertical direction and a diagonal slit 30b extending obliquely downward from the upper end of the vertical slit 30a are formed in the slit 30a. And this slit 3
As shown in FIG. 5, pulleys 31 are movably disposed at 0a and 30b, and a shaft 32 is inserted through the pulleys 31. Further, as shown in FIG. 5, a base end 33a of a lever 33 is fixed to the rotating shaft 29a of the cover opening/closing actuator 29, and the shaft is inserted into a long hole 33b formed in the lever 33. One end 32a of 32 is loosely inserted. Further, this shaft 32 supports a wiper cover 34 that opens and closes the opening 27a of the storage recess 27. Specifically, the wiper cover 34 has a plate shape with substantially the same length as the vehicle width direction, and has a plurality of cover guides 34d protruding downward.
The lower end of is fixed to the other end 32b of the writing shaft 32. On the other hand, the cover opening/closing actuator 29 is connected to a control unit 35, as shown in FIG.
This control unit 35 is connected to a battery 37 via an ignition switch 36. A wiper motor 38 and a wiper switch 39 are connected in series between the control unit 35 and the ignition switch 36. Further, a control unit 35 is connected to the fixed contact side of the wiper switch 39. Furthermore, a warning light 40 as a warning means is connected to the control unit 35. When the ignition switch 360N is turned on, the control unit 35 applies current to the cover opening/closing actuator 29 for a certain period of time.
9 is operating normally, and if the cover opening/closing actuator 29 is not operating normally, it is set to supply current to a warning light 40. Next, the operation of a certain automobile front window wiper storage device based on such a configuration will be explained. When the ignition switch 36 is turned on when the vehicle is started, @ current is supplied to the control unit 35, and current is temporarily supplied to the cover opening/closing actuator 29, and it is determined whether the cover opening/closing actuator 29 operates normally. If the wiper cover 34 does not open or close due to snow accumulation or the like on the wiper cover 34, the cover opening/closing actuator 29 will not operate normally, so current will be supplied from the control unit 35 and the warning light 40 will turn on. Light. As a result, when the vehicle starts, it is possible to confirm in advance whether the wiper cover 34 is not moving, and to operate the wiper cover 34 using the Y4W.

The opening 27a of the storage recess 27 is now opened, the wiper blade 28a moves along the front window glass 12, and the surface of the glass 12 is wiped. On the other hand, when the wiper switch 39 is turned off,
To retract the front window wiper 26, the control unit 35 rotates the cover opening/closing actuator 29 in the opposite direction. Then lever 3
3 is the chain double-dashed line in Figure 4. As shown in the dashed line and solid line, the opening 27a is closed by the wiper cover 34 in the opposite manner to the above. Furthermore, when the front window wiper 26 is in use, the wiper cover 34 is stopped in a substantially horizontal position as shown by the two-dot chain line in FIG. , the air resistance during driving will be reduced. In the above embodiment, the warning light 40 is turned on as a warning means, but the present invention is not limited to this, and an alarm sound may be emitted. [Effects of the Invention] As described above, according to the present invention, when the ignition switch is turned on, a control is provided which applies current to the cover opening/closing actuator for a certain period of time and determines whether or not the cover opening/closing actuator operates normally. By having a unit and a warning means that issues an alarm when the cover opening/closing actuator does not operate normally based on a signal from the control unit, it is possible to confirm the operation of the wiper cover in advance before the vehicle runs. This has the practical effect of making it possible to operate the wiper cover reliably before driving, thereby eliminating the need to stop the vehicle midway through driving, which was the case in the past.
