Nationality: INDIAN
The following specification particularly describes the nature of the invention and the manner in which it is to be performed.

TECHNICAL FIELD
Present disclosure, in general, relates to field of automobile engineering. Particularly, but not
exclusively, the present disclosure relates to a sunroof panel for a vehicle.
BACKGROUND
Sunroofs in automobiles such as cars is a common feature and is usually designed to allow additional sunlight and fresh air into a cabin of a vehicle. Sunroofs usually include a sunroof cavity provisioned on the roof of the vehicle, a sunroof carrier and a sunroof module. The sunroof module may include a retractable glass panel which is disposed on the sunroof carrier, and is operable between an open and a closed position of the sunroof. The sunroofs carriers include guide rails to assist slidable displacement of the glass panel along the sunroof carrier.
In general, assembling various components of sunroofs such as sunroof carries and sunroof modules would increase the weight of components on the sunroof, increased cost and also compromise on the structural integrity of the vehicle roof. Further, the use of sunroof carrier and sunroof module in conjunction may bulk up space occupied by the sunroof, thereby reducing available head space. Further, during coating of vehicle via paints or Cathode electro deposition (CED),complex profile of the sunroof carrier increases accumulation of paint along certain portions of the sunroof carrier and in some cases, paints isn’t deposited in a few ‘hard-to-reach’ areas of the sunroof carrier, which leads to corrosion or other phenomena, which is again undesired.
The present disclosure is directed to overcome one or more limitations stated above. The background section of the present disclosure should not be considered as a limitation of the present disclosure.
The drawbacks/difficulties/disadvantages/limitations of the conventional techniques explained in the background section are just for exemplary purpose and the disclosure would never limit its scope only such limitations.

Embodiments of the disclosure are described in the following paragraphs with reference to Figs. 1 to 6, the same element or elements which have same functions are indicated by the same reference signs.
Fig. 1 illustrates an exploded view of a sunroof panel (100) for a vehicle. As an example, the vehicle can be of at least several different uses and can be referred to as a heavy and light-duty vehicle including but not limited to a work vehicle, a bus, a material hauling vehicle, a fire-fighting vehicle, caravan, and the like. Also, the vehicle may include sports utility vehicles (SUVs), multi-utility vehicles (MUVs), pick-up trucks, and the like without deviating from the scope of the present disclosure. The sunroof panel (100) includes a roof panel (10) defined with a sunroof cavity (15). The roof panel (10) may correspond to a roof of a vehicle provisioned to accommodate a sunroof feature. In an illustrated embodiment, the sunroof cavity (15) includes a square profile. However, the same cannot be construed as a limitation since the sunroof cavity (15)may include any geometrical shape such as but not limited to rectangular, trapezoidal, circular etc.
Now referring to Fig. 2, the sunroof panel (100) includes a plurality of insert members (30) positioned at predetermined positions at an underside portion of a periphery of the sunroof cavity (15). The insert members (30) are light weight and substantially block shaped components. Material of construction of the insert members (30) may be chosen based on specific weight and stiffness of material. In an embodiment, the material chosen for insert members (30) may be defined by low specific weight and high stiffness. In an embodiment,

the insert members (30) may be made of Light weight material such as but not limited to PA66 or Al Alloy. Further, the plurality of insert members (30) may be substantially cuboidal in shape [Best seen in Fig. 6]. In an embodiment, each of the plurality of insert members may include a first portion (31), a second portion (32) and a third portion (33) such that the first portion (31) and third portion (33) are substantially parallel to each other and the second portion (32) connects the first portion (31) to the third position (33). Further, the first portion (31) may be mountable on a predetermined position at the underside portion of the roof panel (10) along the periphery of the sunroof cavity (15). In an embodiment, the first portion (31) may be substantially flat and optionally curved to sufficiently abut a profile of the underside of the roof panel (10). Further, the second portion (32) of the insert members (30) may extend from edges of the first portion (31) at an angle ranging from 70° to 90° relative to an edge of the first portion (31). Furthermore, the third portion (33) of the insert members (30) may extend from the second portion (32). The third portion (33) of the insert members (30) may be substantially parallel to the first portion (31). Additionally, third portion (33) of the insert members (30) may include a depression (16) [Best seen in Fig. 4b] when viewed from below the roof panel (10). The depression (16) may define a geometrical shape such as but not limited to a trapezium, a semicircle, a rhombus, a parallelogram, a square, a rectangle etc in a cross sectional view of the insert members (30). In the illustrative embodiment, the depression (16) defines a geometrical shape of trapezium. In an embodiment, the first portion (31) of the insert member (30) is at least one of adhesively joined, fastened or thermally fused to the predetermined portion at the underside portion of the roof panel (10) along a periphery of the sunroof cavity (15).
Referring to Fig. 3, the sunroof panel (100) may include a plurality of projections (13) extending from a predetermined portion of the roof panel (10) along the periphery of the sunroof cavity (15). Each of the plurality of projections (13) may extend proximal to one of the plurality of insert members (30). The plurality of projections (13) may be spaced equally or unequally between each other. The plurality of projections (13) may define a geometrical shape such as but not limited to a square, a rectangle etc when viewed from a top portion of the vehicle. Further, the plurality of projections (13) may be machined on the roof panel (10) during preparation of cavity (15) by preparing a cutout such that the remaining portion of the roof panel (10) after the cutout is removed may include the plurality of projections (13) extending from the periphery of the cutout i.e., cavity (15) towards the centre of the cavity (15). Furthermore, each of the plurality of projections (13) may be configured to extend around

corresponding insert members (30) to sandwich the insert members (30) between the predetermined position at the underside portion of the roof panel (10) along the sunroof cavity (15) and the corresponding projections (13).
Referring to Fig. 4a-4b, the plurality of projections (13) may be divided to two sections which include first section (14a) and second section (14b) [best seen in Fig. 4b]. During assembly of the sunroof panel (100), the plurality of projections (13) may be configured to wrap/sandwich the corresponding insert members (30). The surface of the plurality of projections (13) may be processed by a forming process to form a depression (16) along the plurality of projections (13). The depression (16) may be formed on at least one of the first section (14a) or the second section (14b) of the plurality of projections (13). In an embodiment, the depression (16) formed on the plurality of projections (13) may be complementary to a profile of the plurality of insert members (30) such that upon bending of each of the plurality of projections (13), the projections (13) sufficiently mesh with at least one portion of the insert members (30). Additionally, the plurality of projections (13) may be configured bend via a first bending stage and second bending stage to sandwich each of the insert members (30) between the roof panel (10) and the projections (13). The first bending stage [Best seen in Fig. 4a] may involve bending each of the projections (13) along the periphery of the sunroof cavity (15) towards a cabin of the vehicle and abut with the second portion (32) [best shown in Fig. 6] of the insert members (30). In the second bending stage [best seen in Fig. 4b], the second section (14b) of the projections (13) may be bent from an end of the first section (14a) and abut with the second portion (32) of the insert members (30). In an embodiment, the depression (16) formed on the plurality of projections (13) may be formed on the second section (14b) of the plurality of projections (13) and may be complementary to a geometrical profile formed on the third portion (33) of the insert members (30). In an embodiment, the second portion (32) and the third portion (33) of each of the insert members (30) may be at least one of adhesively joined, fastened or thermally fused to the first section (14a) and second section (14b) of the corresponding plurality of projections (13).
Referring back to Fig. 1, the sunroof panel (100) includes a sunroof module (20) positioned below the roof panel (10). The sunroof module (20) may include a glass (11) [Best seen in Fig. 2] configured to cover the sunroof cavity (15) to prevent dust and other foreign particles from entering a cabin of the vehicle. Furthermore, the glass (11) may be operable between an open position and closed position of the sunroof panel (100). In an embodiment, the glass (11) may

be displaced in any one of lateral, longitudinal or diagonal direction with respect to the vehicle. Additionally, the sunroof module (20) may include an actuating means to displace the glass (11) between an open position and closed position of the sunroof panel (100). The insert members (30) of the sunroof panel (10) may impart necessary local stiffness to the sunroof panel (100) to prevent bending or deformation of the roof panel (10) by a self-weight of the sunroof module (20). Arrangement of the insert members (30) and the projections (13) along the periphery of the sunroof cavity (15) forms a discontinuous profile below the roof profile unlike conventional arts. This results in sufficient gaps for flow of any coating material/ coating paints to coat the underside portion of the roof panel (10) and the projections (13). Various coating method such as cathode electrodeposition may be used to coat the sunroof panel (100) without accumulation of paint in certain portion of the sunroof panel (100) and allow uniform coating along all surfaces of the sunroof panel (100) due to simpler flow path for coating material/coating paints.
Referring back to Fig. 2, the second section (14b) of each of the plurality of projections (13) and the third portion (33) of the insert members (30) may be defined with a hole to receive a fastening member. In an embodiment, the sunroof module (20) may include a hole such that a fastening member may pass through the hole of the sunroof module (20), the hole on the second section (14b) of each of the plurality of projections (13) and the hole on the third portion (33) of each of the plurality of the insert members (30) to securely connect the sunroof module (20) with the roof panel (10). The plurality of insert members (30) may each include a nut (40) secured within the insert members (30) proximal to the third portion (33). A bolt (50) [As seen in Fig.5] may be passed through the sunroof module (20), the plurality of projections (13) and the insert members (30) to mate with the nut (40) positioned within the insert members (30). Such fastening between the sunroof module (20) and the roof panel (10) may be securely connected for easy access and maintenance of the sunroof module (20). Further, the plurality of projections (13) may include a longitudinal hook (60a) defined on at least one of the first section (14a) or the second section (14b) of the plurality of projections (13). The sunroof module (20) may include a lateral hook (60b) oriented at angle relative to the longitudinal hook (60a). The lateral hook (60b) may be configured to provide additional stability for the sunroof panel (100) by mounting the lateral hook (60b) with the longitudinal hook (60a). In an embodiment, the sunroof module (20) may include a sealing member (12) positioned at least on one of the periphery of the cavity (15) of the glass (11). The sealing member (12) may be configured to ensure sufficient ingress between the glass (11) and the roof panel (10). In an

embodiment, the lateral hook (60b) may further include alternating crevices’ in a curved portion of the hook. The alternating crevices may be provisioned on the lateral hook (60b) to provide sufficient ingress between the roof panel (10) and the glass (11) in a closed position of the sunroof panel (100).
Embodiments and features of the present disclosure advantageously eliminate need for additional mounting structures such as a sunroof carrier to mount a sunroof module (20), rather the configuration having insert members and the projection wrapping the insert members act as mounting structures and also provide local stiffness to the sunroof panel. Further, the simplified construction of the sunroof panel (100) allows for easy cathode electro deposition of the paints on various surfaces of the sunroof panel (100). Furthermore, the insert members (30) impart necessary local stiffness to the sunroof panel (100) to prevent bending or deformation of the roof panel (10) by a self-weight of the sunroof module (20).
In an embodiment, a single insert member (30) may extend along a length of the periphery of the sunroof cavity (15) on either side of the lateral portions of the vehicle to impart same effect as the arrangement of plurality of projections (13) and insert members (30) without deviating from the scope of the present disclosure.
EQUIVALENTS
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
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.”
In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
