AN OUTSIDE REAR VIEW MIRROR (ORVM) GARNISH STRUCTURE OF A VEHICLE
TECHNICAL FIELD
[0001] The present disclosure belongs to an outside rear view mirror (ORVM) garnish structure of a vehicle. In particular, the present disclosure discloses the ORVM garnish structure, where the ORVM garnish structure has been designed and developed in order to improve aerodynamic drag in the vehicle.
BACKGROUND
[0002] In recent times, automobile manufacturers are coming up with a host of features in a vehicle so as to provide smooth driving experience and comfort to the customers. In this context, noise, vibration, harness (NVH) is one of the key performance indicators in the automotive industry and requires careful monitoring.
[0003] Typically, there are three sources of NVH in vehicles. These include mechanical noise, electrical noise and aerodynamic noise. Mechanical noise may arise due to brake friction, engine operation and contact of tire with the road. Electrical noise, on the other hand, may occur due to the malfunctioning of different sensory alerts and inverters present in the vehicle. Aerodynamic noise arises due to flow of wind against the car body and becomes a significant factor of discomfort on increase of speed of the vehicle. The discomfort may further contribute to fatigue in driver impacting vehicle’s performance and safety.
[0004] Therefore, in order to circumvent the challenges witnessed due to presence of aerodynamic noise as mentioned above, the outside rear view mirrors (ORVM) of the vehicle must be designed suitably so as to reduce drag and improve aerodynamic performance of the vehicle.
OBJECTS OF THE INVENTION
[0005] Some of the objects of the present disclosure, which at least one embodiment herein satisfy, are listed herein below.
[0006] It is an object of the present subject matter to overcome the aforementioned and other drawbacks existing in the prior art systems and methods.
[0007] It is a significant object of the present disclosure to design and develop an outside rear view mirror (ORVM) garnish structure so as to improve aerodynamic drag in a vehicle.
[0008] It is another significant object of the present disclosure to design and develop the ORVM garnish structure such that the ORVM garnish structure is able to generate stream wise and optimized vortices.
[0009] It is another object of the present disclosure to design and develop the ORVM garnish structure such that the ORVM garnish structure is capable of reducing drag and wind noise while the vehicle is in motion.
[0010] These and other objects and advantages of the present subject matter, will be apparent to a person skilled in the art after consideration of the following detailed description, taken into consideration with accompanied drawings in which preferred embodiments of the present subject matter are illustrated.

DETAILED DESCRIPTION
[0027] A few aspects of the present disclosure are explained in detail below with reference to the various figures. Example implementations are described to illustrate the disclosed subject matter, not to limit its scope, which is defined by the claims. Those of ordinary skill in the art will recognize a number of equivalent variations of the various features provided in the description that follows.
[0028] While the embodiments of the disclosure are subject to various modifications and alternative forms, specific embodiment thereof have been shown by way of example in the figures and will be described below. It should be understood, however, that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternatives falling within the scope of the disclosure.
[0029] The terms “comprises”, “comprising”, or any other variations thereof used in the disclosure, are intended to cover a non-exclusive inclusion, such that a device, system, assembly that comprises a list of components does not include only those components but may include other components not expressly listed or inherent to such system, or assembly, or device. In other words, one or more elements in a system or device proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or device.
[0030] The present disclosure is related to an outside rear view mirror (ORVM) garnish structure (100) of a vehicle. Herein, the ORVM garnish structure (100) has been designed and developed to improve aerodynamic drag and also reduce wind noise to a considerable extent while the vehicle is in motion. The salient structural features of the ORVM garnish structure (100) have been disclosed in the subsequent sections.

[0031] Figure 1 (a-d) depicts an outside rear view mirror (ORVM) garnish structure of a vehicle in accordance with an embodiment of the present disclosure. Figure 2 (a-c) further depicts different views of the ORVM garnish structure (100) of the vehicle in accordance with an embodiment of the present disclosure.

[0032] In an aspect, it may be observed from Figure 1 (a-d) that the ORVM garnish structure (100) is configured to support the outside rear view mirrors (ORVMs) of the vehicle. Referring to Figure 2 (a-c), it may be further observed that the ORVM garnish structure (100) may comprise of two segments.

[0033] In an aspect, the first segment is a base (102) configured to receive the ORVM and the second segment is a mounting structure (104) perpendicularly extending from the base (102).

[0034] In an aspect, the other end of the mounting structure (104) is connected to an A-pillar of the vehicle. Further, an outer surface of the mounting structure (104) is having a plurality of vortex generators, which in turn are defining a plurality of equilateral triangle shaped protrusions (106).

[0035] In an aspect, these plurality of equilateral triangle shaped protrusions (106) are positioned one after the other along vertical direction. Specifically, these plurality of equilateral triangle shaped protrusions (106) are stacked one after the other defining a separation gap between each of the plurality of equilateral triangle protrusions (106) so as to generate stream wise vortices.

[0036] Referring to Figure 2 (c), the flow adheres more closely around the A-pillar and ORVM garnish structure (100) as thickness (Y mm) of the protrusions (106) is greater than thickness (X mm) of the rear end of the ORVM garnish structure (100), i.e., Y > X. This enhanced attachment leads to increased pressure on the lateral surface of the vehicle, which in turn decreases drag and wind noise.

[0037] In an aspect, referring to Figure 3, the plurality of equilateral triangle shaped protrusions (106) is aligned along an inclined manner such that an apex (106-1) of each of the plurality of equilateral triangle shaped protrusions (106) is oriented along a straight line with respect to an apex (104-1) of the ORVM garnish structure (100).

[0038] In an aspect, each of the equilateral triangle shaped protrusions (106) are positioned in parallel with respect to one another. Moreover, as can be observed from Figure 2 and Figure 3, dimensions of each succeeding equilateral triangle shaped protrusion of the plurality of equilateral triangle shaped protrusions (106) increases with respect to the preceding equilateral triangle shaped protrusions of the plurality of equilateral triangle shaped protrusions (106).

[0039] Figure 4 (a-b) depicts an exemplary working mechanism of the proposed outside rear view mirror (ORVM) garnish structure in accordance with an exemplary embodiment of the present disclosure.
[0040] Referring to Figure 4 (a), it may be observed that flow of air while entering vicinity of the ORVM garnish structure (100) gets hindered and is likely to be deflected along different directions (shown with arrows), due to the positioning and shape of each of the plurality of equilateral triangle shaped protrusions (106). Additionally, the placement of each triangular shaped protrusion (106) is determined to ensure maximum diversion of airflow. Consequently, no airflow will pass uninterrupted in the space between two equilateral triangle shaped protrusions (106). This reduces the wind noise and the aerodynamic drag while the vehicle is in motion.
[0041] Figure 4 (b) illustrates a comparison in working mechanism of the ORVM garnish structure without and with the presence of the plurality of equilateral triangle shaped protrusions (106) as defined by the plurality of vortex generators.
[0042] In an aspect, say in case the outer surface of the mounting structure (104) is flat, the flow of air is continuous, being, not restricted by the corresponding ORVM garnish structure. This direct flow of air contributes towards an increased wind noise and also increases aerodynamic drag of the vehicle. This in turn impacts performance of the vehicle.
[0043] In an aspect, on the contrary, positioning and dimensional arrangement of the plurality of equilateral triangle shaped protrusions (106) as disclosed in the present subject matter, prevents straight and continuous flow of the air. Herein, majority of the airflow streamlines gets attached to the side body of the vehicle due to high pressure and also tends to get deflected in different directions along the plurality of equilateral triangle shaped protrusions (106) as a result of obstruction in flow path provided by these equilateral triangles shaped protrusions (106).
[0044] In an aspect, these frictions between the flow of air and the obstructions generates stream wise vortices (shown in figure 4(b)), effectively blending at the boundary of the outer surface, thereby reducing the air pressure, which in turn reduces the wind noise and improves the aerodynamic drag of the vehicle.
[0045] Therefore, in this manner, the performance of the vehicle is improved by optimization of the dynamics of the air flow.
[0046] Technical Advantages
[0047] All in all, the present invention has the following advantages:
i) Reduces aerodynamic drag in the vehicle
ii) Reduces wind noise in the vehicle
iii) Optimizes airflow dynamics in the vehicle
iv) Ensure comfort in driving the vehicle
v) Improves performance of the vehicle
vi) Improves safety of the vehicle and the passengers

[0049] Although embodiments for the present subject matter have been described in language specific to package features, it is to be understood that the present subject matter is not necessarily limited to the specific features described. Rather, the specific features and methods are disclosed as embodiments for the present subject matter. Numerous modifications and adaptations of the system/device of the present invention will be apparent to those skilled in the art, and thus it is intended by the appended claims to cover all such modifications and adaptations which fall within the scope of the present subject matter.

[0050] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances, where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

[0051] It will be further appreciated that functions or structures of a plurality of components or steps may be combined into a single component or step, or the functions or structures of one-step or component may be split among plural steps or components. The present invention contemplates all these combinations. Unless stated otherwise, dimensions and geometries of the various structures depicted herein are not intended to be restrictive of the invention, and other dimensions or geometries are possible. In addition, while a feature of the present invention may have been described in the context of only one of the illustrated embodiments, such feature may be combined with one or more other features of other embodiments, for any given application. It will also be appreciated from the above that the fabrication of the unique structures herein and the operation thereof also constitute methods in accordance with the present invention. The present invention also encompasses intermediate and end products resulting from the practice of the methods herein. The use of “comprising” or “including” also contemplates embodiments that “consist essentially of” or “consist of” the recited feature.
