Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a wiper/washer system for a vehicle.

``Prior Art'' Wiper systems have become more sophisticated with additional functions such as variable wiper arm pressure and wiper link switching, and in order to prevent noise transmission from the wiper motor, the rigidity of the wiper frame has been increased and as shown in Figure 9. , wiper motor a
It is becoming mainstream to integrally assemble wiper system components such as a wiper link mechanism (not shown because it is on the back side of the frame) connected to the wiper motor a to the wiper frame C.

On the other hand, the mounting position of the washer tank d of the washer system installed alongside the wiper system is highly dependent on the structure of the vehicle and the layout in the engine room, and in some cases, the mounting position may be different even in the same car model. the law of nature,
Along with this, the tank shape and hose piping layout will also differ. This is becoming more and more common as auxiliary parts and various functional parts are being installed on wiper systems that are fixed in position due to the increasing quality and performance of vehicles. The washer tank is installed inside the left and right fenders or in the dead space of the front grille or bumper, as shown in Figure 10. Therefore, the routing of the washer hose e becomes long and complicated.

"Problems to be Solved by the Invention" In the above case, there are design problems such as securing the discharge pressure of the shank knob, increasing the performance and increasing the size. Furthermore, there is a problem in that it is difficult to standardize the line assembly of washer systems even for the same model of vehicle flowing through the production line. Furthermore, there is a problem in that the user cannot easily check or replenish the toilet fluid.

The present invention has been made to solve the above problems, and provides a completely modular wiper/washer system by providing at least a washer tank among the parts constituting the washer system on the wiper frame. be.

``Means for solving rHM'' As a specific means to achieve the above objective, a washer system is configured on a wiper frame to which wiper system components such as a wiper motor and a wiper link mechanism connected to the wiper motor are attached. A wiper/washer system is provided that includes at least a washer tank among its parts.

In addition, the wiper frame to which the wiper system components such as the wiper motor and the wiper link mechanism connected to the wiper motor are attached is hollow-molded, and the hollow part is used as a washer tank.
system is provided.

"Function" Since the wiper/washer system described above has the wiper system components attached to the wiper frame and a washer tank, it can also be used as a wiper/washer system.

Further, by using the hollow portion of the hollow-molded wiper frame as a washer tank, it is possible to modularize the -layer.

"Example" (First example) A first embodiment of the present invention will be described below.

In the exploded perspective view of FIG. 1, reference numeral 1 denotes a wiper frame, and vehicle pan mounting portions 2 are formed at both ends.

A bolt insertion hole 2a is formed in the vehicle body mounting portion 2 for attachment to a wiper frame mounting bracket 27 (see FIG. 3) fixed to the vehicle body 26, which will be described later. A wiper motor mounting surface 3 is provided in the middle in the vehicle width direction, and a vehicle body trim part 2 is also formed on the wiper motor mounting surface 3. Pivot holders 4.4 in the form of tube shafts are erected on both sides of the wiper motor mounting surface 2. Furthermore, washer tank brackets 5.5 are attached to the inner lower surface of the vehicle body trim section 2 on the right side of FIG. 1 and to the lower surface of the wiper motor mounting surface 3, respectively. A wiper motor 6 is fixed to the upper surface of the wiper motor mounting surface 3. 7 is a wiper link, and the pivot holder 4, 4. Left and right levers 9.10 fixed to pivots 8, 8 inserted from below, a connecting link 11 connecting the levers 9.10, and a crank 6a driven by the wiper motor 6 and the lever 10. It is composed of a connecting link 12 and is attached to the lower surface of the wiper frame 1. A wiper arm 14 to which a wiper blade 13 is attached is fitted to the pivots 8, 8 protruding from the pivot holder 4.4, respectively. 15.
Reference numeral 15 denotes a diaper nozzle fixed at a predetermined location on the upper surface of the wiper frame 1.

16 is a flat, horizontally long washer tank, and mounting screws 1 are inserted into mounting flanges 17 and 17 formed on both left and right sides.
8, the mounting flange 17.degree. 17 is fixed to the washer tank bracket 5.5 and mounted on the wiper frame 1. A washer pump 19 is provided in the washer tank 16. A hose 20 connects the washer pump 19 and the offsher nozzles 15 and 15.

21 is a cap fitted to the water supply port of the washer tank 16.

The wiper/washer system integrally modularized as described above is installed in a cowl box 23 formed at the rear edge of the engine hood 22, as shown in FIG. The cowl box 23 is the cowl inner panel 24
and a cowl outer mantle 25, and wiper frame mounting brackets 27 fixed to the vehicle body 26 protrude inward from both left and right ends thereof, as shown in FIG. The mounting portion 2 of the wiper frame 1 is mounted on this wiper frame mounting bracket 27, and is mounted and fixed by a mounting bolt inserted into the bolt insertion hole 2a. The cowl 23 is then covered with a louver 28.

4 and 5 show a modified embodiment of the first embodiment, in which the washer tank 36 is fixed to the upper surface of the frame 1. A through hole 37.37 is formed through which the pivot holder 4.4 of the wiper frame 1 passes, and a washer nozzle 15.15 is fixed at a predetermined location on the upper surface of the washer tank 36, and a washer nozzle 15.15 is provided on the side surface. Mounting flanges 39 and 39 are formed on both left and right ends of the washer tank 36, and the washer tank brackets 5a and 5 on the upper surface of the wiper frame 1 are mounted.
Attach to a. Then, as in the first embodiment, it is mounted inside the cowl box 23 (FIG. 5). In this case, the washer tank 36 is colored the same color as the vehicle, and at the same time, the mounting flange 39 is attached as shown by the chain line in FIG. By integrally molding the cowl cover shape (louver shape) 40 and 40 following 39, there is no need to make the cowl cover a separate part.

Note that the same components as those in the first embodiment are given the same reference numerals and the description thereof will be omitted.

Further, FIG. 6 shows an embodiment in which L-shaped mounting brackets 47, 47 are fixed to the lower surface of the wiper frame 1, and a conventional washer tank 46 is mounted thereon.

In the first embodiment and each modified embodiment, at least the washer tanks 16, 36 and 46 of the components constituting the washer system are integrated into the wiper frame 1 having the above-described configuration and to which the components of the wiper system are attached. By providing a wiper/washer system, it is completely modular. Therefore, as an advantage for the automobile manufacturer, it is possible to downsize the production line and reduce the number of assembly steps.

In addition, the washer tank mounting layout can be unified, reducing the number of washer tank parts between the same vehicle models, and eliminating the length of the washer hose and washer pump harness, contributing to cost reduction. Furthermore, it becomes easier to secure tank capacity, and the layout of auxiliary equipment in the engine room will not be affected by higher-class vehicles, etc., making it possible to greatly expand the degree of freedom in designing the engine room layout. .

In addition, the wiper/washer system is installed inside the cowl in the center of the vehicle body, which centralizes the weight and improves vehicle handling stability, and the wiper/washer system is made into a dynamic damper to reduce body vibration. It is also possible to contribute to the reduction. Furthermore, by surrounding the wiper motor with the washer tank, it is possible to reduce the temperature rise of the wiper motor and the noise of motor operation. On the user side, there are advantages such as improved serviceability, such as easier replenishment and inspection of the toilet fluid.
