Description

Device for cleaning exterior mirrors of automobiles

technical field

The utility model relates to an exterior rearview mirror device for cleaning automobiles, especially trucks or similar vehicles.

Background technique

Motor vehicles all have at least one - preferably two - exterior rearview mirrors which are exposed to the atmosphere, and in the event of bad weather, the exterior rearview mirrors often become dirty very quickly, sometimes to the point of being unusable.

This drawback was exacerbated by the development and use of exterior mirror defrosters, because resistors were placed behind part of the mirror. In fact, the heating of the mirror causes dirt to dry out, making it harder to remove.

These disadvantages are all the more serious for rear view mirrors of transport vehicles such as trucks, since in addition to having a larger mirror surface, said rear view mirrors are exposed for a long time.

These deficiencies relate in particular to the rearview mirror which is farther from the driver, that is to say the one to the right when the driver's position is on the left, since the other rearview mirror is next to the driver and is generally within easy reach.

In order to overcome this defect, a rearview mirror with a wiper device has been proposed, which includes a wiper strip mounted on the end of a rocker arm that pivots to move the wiper strip from left to right Alternate motions to scratch the mirror. However, its effect is very limited.

Utility model content

The purpose of this utility model is to propose a kind of device that can overcome these defects and be used for cleaning the exterior mirror of automobile especially truck or similar vehicle.

According to the utility model, the device for cleaning the exterior rearview mirror of a car, especially a truck, includes a wiper strip that can move close to the surface of the mirror surface of the rearview mirror, and its main feature is that the wiper strip passes through itself The ends of the wiper strip are held by parallel guide rods, and the wiper strip is connected to the transmission device that enables the wiper strip to move in a direction perpendicular to itself. The guide rod is integrated with the mirror surface from the back of the mirror surface. The water strips are attached to the mirror surface by a device whose shape conforms to the edge of the mirror surface.

The movement of the wiper strip in the vertical direction makes cleaning of the mirror more effective, while the attachment of the wiper strip by the ends allows ideal integration of the device, as opposed to systems with pivoting arms.

According to another additional feature of the washer device according to the invention, the guide rod is formed by guide rails or the like arranged close to two opposite edges of the mirror, to which guide rails the ends of the wiper strip are connected by sliding pairs.

According to another additional feature of the washer device of the invention, the wiper strip is supported by an arm, the end of which is connected to the guide rod by a sliding pair.

According to another additional feature of the device according to the invention, the arm comprises means capable of bearing the wiper strip against the mirror surface in an adjustable manner.

According to another additional feature of the device according to the invention, the means enabling the wiper strip to be applied to the mirror surface comprise elastic means interposed between the arm and the wiper strip.

According to another additional feature of the device according to the invention, the wiper strip cooperates with means for spraying washer fluid on the surface of the mirror.

According to a particular embodiment of the cleaning device according to the invention, the guide rods are formed by parallel rods, each of which is provided with a slider capable of sliding on it and supporting one end of an arm connected to the wiper strip. One piece, while the slider is connected to a toothed belt or similar stretched over two pulleys, one of which is driven by at least one motor unit.

Description of drawings

The advantages and characteristics of the device according to the invention will appear more clearly in the ensuing drawings and description, which show a non-limiting embodiment. In the attached picture:

Fig. 1 shows a partial front view of the exterior rearview mirror cleaning device according to the present invention;

Fig. 2 shows the side partial schematic diagram of this device;

Fig. 3 shows a schematic front view of a rearview mirror equipped with a cleaning device of the present invention.

Detailed ways

As can be seen from these figures, the exterior rearview mirror cleaning device of the present invention includes two guide rods 1 arranged parallel to each other on both sides of the mirror surface 2 of the rearview mirror, and an arm 3 that moves along the guide rods. The arm supports a wiper strip or similar 4 , which is not visible in FIG. 2 .

Each end of the arm 3 is equipped with a slide block 30 that can slide along the guide rod 1, which can be a rod or a pipe whose end is fixed on the rearview mirror housing not shown in the figure.

It will be noted that there is often the possibility of moving the mirror due to the adjustment of the field of view, which requires the provision of movement accompaniments which preferably integrate guide rods with the mirror, for example behind the mirror. In this case, the profile of the end portion of the arm 3 should be made to conform to the edge profile of the mirror 1 .

It can be noticed that the guide rod can be parallel to the mirror surface 1 only if the guide rod has the same shape as the mirror surface. In practice it is possible to use spherical mirrors, in which case the guide rod 1 should have the same curvature.

The device of the invention also includes the transmission of the arm 3, which comprises two toothed belts 5 or similar - only one visible in Fig. The wheels 50 are tensioned between each other and are fixedly connected to the slider 30 .

Two opposing pulleys 50 are supported by the same shaft 51 which is driven in rotation by an electric motor 52 . The rotation of the motor 52 rotates the shaft 51 and thus the pulley 50 and the toothed belt or similar 5 , thereby moving the arm 3 due to the integral connection of the slider 30 to the toothed belt or similar 5 .

The movement of the arm 3 and of the wiper strip 4 can be carried out in different sequences, so it can be set as a simple movement in one direction, followed by a return movement, in fact a reciprocating movement, during the washing process.

In addition, the arm 3 is equipped with means to enable the wiper strip 4 to rest against the mirror surface 2, this device includes a spring not visible in the figure, which is inserted between the arm 3 and the wiper strip 4 and is used for adjusting Associated with the screw 31, this screw can be tightened or unscrewed to change the pressure exerted on the spring.

The device of the present utility model is also matched with the spraying device 6 of the mirror surface 2, and the spraying device has a plurality of nozzles 60 at the bottom. In this case, the washer fluid reservoir is preferably arranged in the rear view mirror housing, not shown, and has a visual display.

Another advantageous method can be noted, providing one or more nozzles directed towards the driver's glass from the side towards the right side of the mirror, so that the mirror is always well visible.

Referring now to FIG. 3 , a rearview mirror 7 with a fixed claw 70 can be seen, which rearview mirror is also equipped with the cleaning device of the present invention.

The mirror surface 2 can be seen between two edges 20 on which a slide 30 can slide, which slides the arm 3 on which the wiper strip 4 is mounted. It may be noted that in this embodiment the arm 3 is positioned vertically and moves laterally.

Also visible in this figure are two washer fluid nozzles 60 .
