Description

External Back Mirror for Automobile}

TECHNICAL FIELD The present invention relates to an exterior rearview mirror for an automobile, and more particularly, to an exterior rearview mirror for a vehicle that is designed to be attached to a side of a vehicle and is suitable for a vehicle.

External mirrors of this kind are first known from DE 29704227 U1. This external post change is suitable for the car and constitutes a single item, including a rearview mirror case with a reversible glass. Reflective mirrors are designed with a special curved surface to better capture the blind spot. Reflective mirrors are generally convex spherical bends in the form of convex spherical bends toward the side of the vehicle, and away from the side of the car, to the outer periphery of the aspherical bends to better capture the blind spot. In the middle, a planar intermediate region is arranged. In the general design, the glass surface is vertically attached to the car, and the outer peripheral area of the aspherical surface is installed parallel to the mirror surface.

The middle area between the main field of view and the outer peripheral area is mainly visually distinguishable by the dividing line set on the mirror surface by laser transfer of the reflective layer and the protective coating layer.

Another type of rearview mirror is known from DE 19537902 A1, according to which it is known for enlarging the rear field of view. This rearview mirror is suitable for the car, and it is attached to the car using a fixing device, which can be placed in a single frame and installed in the corresponding position. This rearview mirror points to another slowly changing mirror cross section, in addition to the main mirror directly towards the side of the car, which is attached at least above, below or on the side of the main mirror. This slowly changing mirror section passes through a circular arc and has a curved surface and a hyperbolic curve whose curvature radius is calculable according to the equation and gradually decreases.

On the other hand, according to DE 3828221 A1, a car rearview mirror with an adjustment device is known, which is designed to be adjusted from the normal position to the parking position or the highway driving position and then to the normal position again. In this case, the reflecting surface of the outer mirror is attached to the flexible deformable support plate, which contains at least one adjustment element, which is attached to the support plate, which, when the adjustment device operates Starting from a given normal position, the arch should be convex or concave to suit the operating position when parking or driving on the highway.

For such exterior rearview mirrors with one main mirror section and another mirror section directly facing the car, it is often limited to enlarge the field of view behind the car. Mirrored objects can appear distorted, and most of these designs are expensive to manufacture. External mirrors that can switch positions such as "normal position", "parking" and "highway driving" are very expensive to adjust the position, and can cause adjustment and error.

The present invention has been made to solve the above-mentioned problems, and in particular, it is an object to provide an external rearview mirror which ensures an improvement in a wide field of view and a rear field of view (by reducing image distortion).

According to the present invention the problem has been solved through the design features of the claims.

In the case of an external rearview mirror in a single system with a main reflecting zone and an additional reflecting zone as in the present invention, the first advantage is that the additional reflecting zone is located directly on the side of the vehicle, and then the central field of view is located away from the side of the vehicle. In this case, the additional reflection area, which is directly facing the vehicle, is mainly designed in a curved shape so that the rear view can be enlarged, and in particular, to catch the blind spots well. The main reflection area of the curved shape, which is installed at regular intervals, is the main task of monitoring the rear view, which is essentially determined by the driver's normal field of view (central field of view). A single form of external rearview reflector system thus encompasses the main reflecting area at a distance from the vehicle and an additional reflecting area directly in contact with the vehicle. At this time, the arch shape of the additional reflection area is designed in a concave shape to improve the rear view including the blind spots, and the main reflection area is designed in a convex shape.

The single type of rearview system also has the advantage of being installed in one case which is open to the rear, opposite the direction of travel of the vehicle. The reflector system in the case can then be adjusted primarily or manually (automatically) by motor power.

Another advantage is that rearrangement of the main and additional reflecting zones significantly improves the rear and side field of view. This can also increase stability during operation.

Another advantage is that at least the additional reflecting area is larger in length (vertical) than in width so that it can enter the driver's field of view by means of a lane located on the side of the driving vehicle or a corresponding ground reflector system. It is possible. This can improve the field of view, for example, when parking or when contact with the ground is to be avoided.

The external rearview mirror system according to the invention also has the advantage that it is possible to mount at least the first lighting system in an integrated form in the case. The lighting system illuminates lanes and ground on the side of the car to help the vehicle back up. The lighting system is individually operable or designed to operate mainly in reverse direction. The lighting system is designed to shine toward the lane or the ground so that it does not cause glare to at least the interior of the vehicle.

Another advantage of the external rearview mirror system of the present invention is that, in addition to the first lighting system, the second lighting system can be mounted in the form of being integrated into the case or attached to the outside of the case for driving in reverse. . In this case, the second lighting system is a turn signal (blinking light) that also includes a warning light function, and can be mounted on the outer part of the case mainly away from the vehicle or the occupant. It can be mounted on the outside of the vehicle away from the vehicle and the occupant, and this lighting system can be connected to the vehicle lights (downlight control headlights, distant headlights / high beams, parking lights). This lighting system can be attached to the outside of the reflector case mainly in the direction of travel of the vehicle. This allows the front vision of the vehicle to be better illuminated, for example when parking. In addition, the functions of the above lighting system can be interconnected. For example, a lighting system used as a turn signal may also function as a vehicle width light in a turn signal mirror of an exterior rearview mirror. The first to fourth lighting systems can be connected individually or in groups to be operable or in the form of a fixed function. Significant improvements have been made to the field of view of the rear, side and areas facing the ground and driveway through the exterior rearview mirror according to the invention. The rear view is also improved through the design of the main and additional reflecting zones.

Another preferred embodiment of the present invention is that the vehicle exterior rearview mirror is a single part reflector system having the following characteristics. At least the first lighting system is integrated into the case and functions to illuminate the lanes or ground located on the side of the vehicle, mainly in the rear (ie, in the opposite direction of the forward movement of the vehicle). In technical terms it is mainly associated with the operation of reverse gears. In addition, the first lighting system can be opened (on / off) by manually operating a separate switch if necessary. The first lighting system is attached to the case so that at least a vehicle occupant does not cause glare (reflection). The actuable first illumination system improves the field of view, in particular rearward and downward, and also improves the driver's field of view. In this regard, Figure 7 shows its general form.

In another preferred embodiment of the exterior rearview mirror according to the invention the first illumination system for illuminating the lane to the ground of the vehicle side is functionally connected with another illumination system for illuminating the front field of view of the vehicle side. This lighting system corresponds to the fourth lighting system described above. In general, the two lighting systems can be turned on or off by operating the reverse gear or by operating a switch. In another form, the single lighting system functions as the first lighting system and the fourth lighting system. It is integrated into the system. In other words, this means that the lighting for the rear lane and the rear ground and the front field of view are switched on or off by operating the reverse gear or one switch using one common luminaire or two separate luminaires. ) Is possible.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the outer rearview mirror 1, which is made to be adjustable and foldable, includes a case 5. The reflector case 5 can be fixed to the side surface 9 of the vehicle, for example, an A-shaped prop of the vehicle by using the mounting table 10. The case 5 has an opening 6 in which the single reflector system 4 is arranged in an adjustable form. An opening 6 located between the case 5 and the reflector system 4 is provided with a gap to serve as a free space required for adjusting the reflector system. The opening 6 is directed toward the rear end opposite to the direction of travel of the vehicle. The unitary reflector system 4 shows the main reflecting zone 2 and the additional reflecting zone 3 for the central field of view. The additional reflection area 3 further enlarges the field of view to the rear and makes it possible to capture the blind spot in particular. In the reflector system 4 the additional reflecting zone 3 is located directly in the direction of the vehicle side 9, and the main reflecting zone 2 is located in a direction away from the vehicle side 9. The additional reflecting area 3 is concave arched to enlarge the field of view. The main reflection areas 2 which are located next to each other are convex arcuate. In the reflector system 4 there is generally a connecting portion 15 between the additional reflecting region 3 and the main reflecting region 2, which is essentially vertical. In most cases, when viewed from above, the reflector portion including the bend initiation portion 16 of the concave reflector 7 located on the vehicle side 9 is located in front, and the main reflection area pole 17 of the convex reflector is located at the bend initiation portion ( It is located behind 16). At this time, the deviation angle of the interval is defined by Δ.

In another type of construction, a concave mirror 7 (additional reflection area 3) in which the bend radius of the convex mirror 8 (main reflection area 2) starting at the connection part 15 ends at the connection part 15. Is greater than the bending radius.

In another form, the additional reflecting region 3 is longer than the main reflecting region 2 in the form of a height larger than the width (in the vertical direction). In this case it is possible to better describe the ground located on the side of the vehicle, for example a driveway or ground. In this case, the additional reflection area 3 may have a curved shape with a stronger deviation in the vertical direction, in which case it is possible to enlarge the field of view in the ground direction. At this time, the curvature has a deviation from the vertical line in the traveling direction of the vehicle.

In addition to the form of the reflector system 4 described above, another important form may be a form in which the first illumination system 11 is integrated into the case 5 of the outer rearview mirror 1 as shown in FIG. 2. Hereinafter, a description will be given with reference to FIGS. 2 to 6. The first lighting system 11 is primarily for illuminating the ground located at the bottom of the reflector system 4 and located on the side of the vehicle. Simultaneously with the vehicle reversing, the first lighting system 11 is operated to significantly improve the clock situation, for example in reverse parking. The first lighting system is then mounted so as not to cause glare to the occupants.

The case 5 of the outer rearview mirror 1 is mounted with one lighting system or several lighting systems individually or in combination. The second lighting system 12 is a direction indicator light including a warning light function, and is mounted on the part 5 away from the vehicle side 9 in the case 5. The second lighting system 12 is mounted in the form attached to the case 5 when traveling forward, backward and laterally (at a position farther from the vehicle side 9).

The third lighting system 13 is mounted on the outside of the case 5 as a vehicle width lamp so as to be easily seen. With this third lighting system it is possible to clearly recognize the actual vehicle width, especially in dark places. In terms of operating technology, the third lighting system 13 is used, for example, in connection with a vehicle light such as a downlight headlight, an upright headlight, a parking light or in the form of a combination to meet the desired requirements.

The fourth lighting system 14 is integrally mounted to the case 5 by a print or the like and serves to illuminate the traveling direction of the vehicle. This improves the illumination of the printed field of view, which is an advantage when parking or changing lanes.

The first lighting system 11 to the fourth lighting system 14 are mounted so that there is no glare phenomenon. For example, it can be selectively mounted on or inside the case 5 of the outer rearview mirror 1. Alternatively, glass that transmits light without tinting or glare in the form of a combination can be used for the first illumination system 11 to the fourth illumination system 14. These glasses can transmit light in white, yellow, orange, red or black to meet your needs. The functions of the first lighting system 11 to the fourth lighting system 14 can be interconnected in operation technology, so that there are fewer lights than the four lighting systems 11, 12, 13, 14 described by way of example. The same can be done with a system.

The reflector system 4 can be made of glass or synthetic resin in terms of material. The outer rearview mirror 1 of the present invention can be attached to one side or both sides of the vehicle.

A preferred embodiment of an automotive exterior rearview mirror with a case 5 fixed to a vehicle and a generally adjustable reflector system 4 is shown in FIG. 7. The outer rearview mirror 1, like the other forms described above, enlarges the field of view and improves the field of view backwards. The reflector system 4 is also manufactured in the form of a single piece. Generally, the width in the horizontal direction is longer than the height in the vertical direction. This form is particularly suitable for passenger cars. The reflector system 4 is also installed in the case 5, which is directed rearward, in which the opening is opposite to the direction of travel of the vehicle. The case 5 is fixed to the vehicle side 9 by means of the attachment device 10. In this case, the reflector system 4 can be manufactured in various forms. Based on the cross-section D-D of FIG. 7, various selected forms of the reflector system 4 are presented in FIG. 11.

11a shows a reflector system with a concave mirror 7. The concave mirror 7 faces the vehicle side 9, which is a planar reflector from the connector 15 and a convex mirror 8 from the second connector 17. The convex mirror 8 is farthest from the vehicle side 9 and serves to enlarge the field of view. In FIG. 11B, the reflector 19 is shown in a fully planar form. FIG. 11C shows a complete convex mirror 8, and FIG. 11D is another form of FIG. 11C with the end of the convex mirror 8 being a planar reflector. These forms show a side view of the outer rearview mirror 1 of FIG. 8, in particular of the reflector system 4, which is generally flat or curved according to section A-A of FIG. 7.

The reflector system 4 is a convex mirror in which the lower part always curves along the vehicle traveling direction, whether planar or curved. In this regard, FIG. 7 shows a horizontal connection 18. Underneath this connection 18 all reflector systems 4 are convex and curved, which makes it possible to improve the visibility of the lane or the ground located on the side of the vehicle. The lower part is generally in a substantially symmetrical form underneath the horizontal arrangement of the connections 18 in the reflector system 4, as can be seen in FIG. 7.

In another form of FIGS. 9 and 10, a plan view (section D-D of FIG. 7) of a reflector system is shown. Referring to Fig. 9, the reflector system 4 is in the form of an even curved surface. On the other hand, in Figure 10, the degree of bending of the reflector is far away from the side of the vehicle is severe, especially for better capturing the blind spot.

Common to all forms according to FIGS. 7 to 11 is that a first lighting system 11 is attached to the case 5 for illumination of the ground located on the side of the vehicle. This illumination system 11 generally does not cause glare and is attached to the case 5 at the bottom or side of the reflector system 4. Fig. 7 shows one of the general forms, which are approximately equal in height to the connecting portion 18 in the horizontal direction. On the side of the reflector system 4, a second illumination system 12 is generally attached to the case 5 with a turn signal lamp and a third illumination system 13 with a traffic light. In another embodiment, the fourth lighting system 14 is directly arranged in series with a headlight or a position light for the ground lighting in the first lighting system 11. In this case the illumination of the front part of the side of the vehicle is improved. Such a form can be manufactured in such a way as to separate or integrate the first lighting system 11 with its own lighting means or integrated lighting means. At least the first lighting system 11 can be opened or closed in conjunction with the operation of the reverse gear or via a switch. These two lighting systems 11 and 14 are generally operated by reverse gear operation or can be manually switched on and off. Thus, regardless of the type of reflector system 4 arranged in the case 5, the driver's field of vision is significantly improved by operating at least the first lighting system 11 and mainly operating the fourth lighting system 14 simultaneously. can do. When combining the first illumination system 11 or mounting the two illumination systems 11, 14 via a convex curved surface disposed at the lower portion of the reflector system 4 (lower portion of the connection 18), The watch situation can be significantly improved. In this case, the lighting systems 11 and 14 can be directed toward the ground of the front and the rear even when installed in the lower portion of the connecting portion 18.

As described above, the exterior rearview mirror for a vehicle of the present invention enables the driver to secure a wide field of view and entails the effect of achieving an improvement in the rear view by reducing image distortion.

Preferred embodiments of the present invention are disclosed for purposes of illustration, and those skilled in the art may make various modifications, changes, additions, and the like within the spirit and scope of the present invention, and such modifications, changes, and the like should be regarded as belonging to the following claims. something to do.
