Description

The invention relates to transport machinery, and more particularly to the design of structures of the so-called external double rear-view mirrors for vehicles.

There are various designs of external double rear-view mirrors for vehicles (see, for example, the certificate of the Russian Federation for utility model N 26210, B 60 R 1/02, 1/06, 2002; French application N 2808752, B 60 R 1/02, 2001). Such mirrors, each with two mirror elements, provide the driver with a more complete view of the rear view than conventional mirrors with one mirror element, however, their use in some applications is not effective enough, for example, due to the location of an additional mirror next to the main mirror, which makes it difficult overview of the so-called "dead zone".

In addition, when the mirror elements are located nearby, there is insufficient rigidity of the entire structure, since it is possible to move the additional mirror element relative to the main mirror in a vertical plane from inertial loads arising from the movement of the vehicle.

The closest solution in technical essence and the achieved effect from its use to the claimed one is the known design of an external double rear-view mirror according to the application WO 02/32723, B 60 R 1/08, 2002, containing an L-shaped stand fixedly mounted on the vehicle body and connected through a neck to a housing in which two nests are arranged one below the other, separated by a partition, and in the upper nest there is a main mirror kinematically connected to its orientation mechanism, yaemogo both the inner and the outer side of the vehicle, and the lower nest taken additional mirror fixedly mounted relative to the housing, wherein the housing is rotatable in a horizontal plane relative to the L-shaped rack.

This design, although it allows the driver to provide a more complete view of the rear view than a conventional mirror with one mirror element, however, the use of such an external double mirror in some applications is not effective enough,

firstly, due to insufficient structural rigidity due to the possibility of unauthorized movement of the housing relative to the support in the vertical plane from inertial loads arising during the movement of the vehicle, which reduces the reliability of its operation;

secondly, due to the unwarranted degree of visibility of the environment (under the conditions of increasing visibility requirements due to the sharp increase in traffic flows), due to the uncertainty in the size ratios of the main structural elements of the exterior double mirror;

thirdly, because of the condensation that forms on the primary and secondary mirrors in the cold season and in cloudy weather, the use of these mirrors is difficult.

The problem to which the invention is directed, is to significantly improve the reliability and increase the functionality of the external double rear view mirror.

This problem is solved using the technical result from the use of the claimed invention, which consists in:

firstly, in ensuring the highest possible degree of visibility to the driver of the environment by providing him with the most complete information with optimal weight and size characteristics of the design of the external double mirror,

secondly, to increase the reliability of the structure by eliminating the possibility of unauthorized vertical movement of the body relative to the support, and therefore relative to the vehicle body during movement,

thirdly, to increase the ease of use of mirrors by eliminating their fogging or freezing.

This result is achieved by the fact that in the known external double rear-view mirror containing an L-shaped pillar fixedly mounted on the vehicle body and connected through the neck with a housing in which two nests are arranged one under the other, separated by a partition, and in the upper nest a main mirror is placed kinematically connected to the mechanism of its orientation, and in the lower socket there is an additional mirror fixedly mounted relative to the housing, the housing being made with the ability to rotate in a horizontal plane relative to the L-shaped rack,

firstly, the main mirror, along with its orientation mechanism, is mounted on a vertically located inside plate made of plastic and a support plate fixed relative to it, in the lower part of which there is a horizontal hollow bracket located at an angle to the front surface of the support plate, which, in in turn, it is pivotally connected to the horizontal shelf of the L-shaped rack, and the L-shaped rack, the support plate and the horizontal hollow bracket are made of metal, for example imer made of aluminum or zinc alloy,

the L-shaped plastic decorative cover is put on and on the L-shaped stand from the side of its horizontal shelf, the plastic decorative lining is fixed on the outside from the outside, and the neck is closed from the outside with two plastic linings - front and back, fixedly mounted on the horizontal hollow bracket and provided with a node for their mutual fixation, made, for example, in the form of a latch,

secondly, the main mirror in shape is made in the form of a vertically elongated rectangle with rounded corners, and the additional mirror is made in the form of an inverted trapezoid with rounded corners, located symmetrically relative to the vertical axis of the main mirror, and the main and additional mirrors are made with the following relationship of parameters:

where: S _add - the area of the additional mirror;

S _DOS - the area of the main mirror,

thirdly, the primary and secondary mirrors are equipped with the primary and secondary electric heaters fixed to them, respectively, connected to the vehicle electrical system.

Introduction to the above-described design of new units and elements, as well as the special implementation of existing units and elements, can significantly increase the reliability and improve the operating conditions of the external double rear-view mirror.

The proposed external double rear-view mirror contains (see Fig. 1, 7) an L-shaped pillar 1 fixedly mounted on the vehicle body (not shown in the drawing) and connected through a neck 2 to a body 3 made of plastic, in which two nests located one below the other, separated by a partition 4, and in the upper socket there is a main mirror 5 kinematically connected to its orientation mechanism 6 (see Figure 2), and in the lower socket there is an additional mirror 7 fixedly mounted relative to building 3 and installed at a constant angle to the front plane of the housing 3 (so that the driver can observe the side of the car, including the corresponding rear wheel, when performing a maneuver of parking the car or so that the driver can observe the cars going behind when they are in the so-called "dead zone"), and the housing 3 is made with the possibility of rotation in a horizontal plane relative to the L-shaped rack 1.

The main mirror 5 together with its orientation mechanism 6 are mounted on a vertically located inside the housing 3 and fixedly mounted relative to it, for example, by means of the upper 8 and lower 9 latches (see Fig. 7) of the support plate 10, in the lower part of which there is a angle to the front surface of the base plate 10 (see Fig. 8) a horizontal hollow bracket 11, which, in turn, is pivotally connected to the horizontal shelf 12 of the L-shaped rack 1, and the L-shaped rack 1, the base plate 10 and the horizontal is empty the separate bracket 11 is made of metal, for example of aluminum or zinc alloy.

Moreover, on the L-shaped rack 1 from the side of its horizontal shelf 12 (see Fig. 1, 7), a L-shaped plastic decorative cover 13 is put on and fixed relative to it, while on the case 1 is outside (see Figure 3, 4) a decorative plastic cladding 14 is fixed, and the neck 2 is closed externally by two plastic pads - front 15 and back 16 (see Figs. 1, 3), fixedly mounted on a horizontal hollow bracket 11 (see Fig. 7) and equipped with their assembly mutual fixation, made, for example, in the form of a latch (not shown in the drawing).

The main mirror 5 in shape is made in the form of a vertically elongated rectangle with rounded corners, and the additional mirror 7 is made in the form of an inverted trapezoid with rounded corners, located symmetrically relative to the vertical axis of the main mirror 5, and the main 5 and additional 7 mirrors are made with the following experimentally installed correlation of parameters:

where S _add - the area of the additional mirror 7;

S _osn - the area of the main mirror 5.

In addition, the main 5 and additional 7 mirrors are equipped (see FIG. 2) with the main 17 and additional 18 electric heaters fixed to them, respectively, connected to the vehicle’s on-board electrical network, which ensure frost freezing during the cold season and condensate evaporation in the cloudy the weather.

In addition, (see Fig.2, 5, 6) there is a mechanism for turning the housing 3, for example, in an emergency (and returning it to its original position after the emergency), located between the horizontal hollow bracket 11 and the horizontal shelf 12 L- shaped rack 1. In this case, the rotation mechanism of the housing 3 includes a threaded sleeve 19, fixedly mounted on the horizontal shelf 12 of the L-shaped rack 1, on which is mounted a horizontal hollow bracket 11, spring-loaded with a calibration spring 20, equipped with an adjusting nut 21, on Revert to the threaded sleeve 19.

In this case, the rotation mechanism of the housing 3 is equipped with a position lock of the housing 3 in three positions (see Figure 5), made in the form of three trapezoidal cross-section protrusions 22 on the horizontal shelf 12 (ohm. Figure 9) and reciprocal depressions on the horizontal hollow bracket 11 .

The proposed external double rearview mirror is operated as follows.

Before starting operation in the manufacturing process, an additional mirror 7 is installed with rotation by the required angle and its fixation for each specific vehicle. In addition, calibrate the actuation force of the rotation mechanism of the housing 3 using the adjusting nut 21 (see Fig. 2, 6), selecting the desired rigidity of the calibration spring 20 of the actuation force of the rotation mechanism of the housing 3. After adjusting the rotation mechanism of the housing 3, the adjusting nut 21 is fixed with using anaerobic sealant to prevent deregulation of the mechanism while the vehicle is in motion.

Then the driver of the vehicle sets the desired position of the main mirror 5 to obtain the desired visibility from the driver’s seat, for which he directly from the driver’s seat with the passenger compartment door closed, using the control element (not shown) turns the main mirror 5 relative to the body 3 by the required angle and fixes it .

During the vehicle’s movement in a normal situation, the driver uses the proposed external double rear-view mirror in the usual way. In this case, the housing 3 with the configured primary 5 and additional 7 mirrors inside is located in the middle working position 23 (see Figure 5).

In an emergency situation, for example, when the hull 3 hits an obstacle, the hull 3 rotates along the vehicle body to the 24 or 25 position depending on which side the load acts, thereby mitigating the impact. At the same time, since the folding force does not depend on the angle of rotation, the impact is softened more effectively.

After eliminating the consequences of the emergency before resuming the vehicle’s movement, the driver manually, holding the case 3, returns the case 3 with the mirrors 5 and 7 to the initial operating position 23.

The use of the claimed invention allows:

1. Significantly increase the visibility of the environment by providing the driver with the most complete information with optimal weight and size characteristics of the exterior double mirror design.

2. Significantly increase the reliability of the external double mirror by eliminating the possibility of unauthorized vertical movement of the housing relative to the support, and therefore relative to the vehicle body during movement.

3. Improve the usability of the external double rear-view mirror by eliminating fogging or freezing of the primary and secondary mirrors.

4. To increase the external attractiveness of the external double rear-view mirror through the use of various additional decorative elements that allow the use of different color combinations of different parts of this product, while ensuring their reliable tightness.
