,TagSPECI:TECHNICAL FIELD

Embodiments of the present disclosure relates to a vehicle body structure. In particular, embodiments include a common rear part structure of the vehicle body for accommodating either one of swing type tail gate and fixed type tail gate.

BACKGROUND OF DISCLOSURE

Automotive vehicles, such as but not limiting to hatch back cars, station wagons, pick-up trucks, Sport Utility Vehicles, Multi Utility Vehicles, and estate cars are commonly employed with a tail gate. The tailgate is a type of door for the vehicle that is generally mounted at a rear opening of the motor vehicle to restrict or permit access to a rear compartment of the motor vehicle. In the tail gate open position it permits access to a rear compartment of the motor vehicle, so that cargo/league may be easily loaded into and unloaded from the boot/league space. The tailgate will be connected to rear part structure of the by the means such as but limiting to hinging, pivoting, and fixing.

Generally, the conventional vehicles are provided with only swing type of tailgate option to fix only one variant of tail gate i.e. either swing type tailgate construction having hinge axis at top of the tailgate assembly or fixed type of tail gate which can be removably fixed to rear part structure of the vehicle. The swing type tail gate may be hinged to roof bow structure of the vehicle for pivotable movement along the aft-end of the vehicle’s roof. Such pivotable attachment of the tailgate to the vehicle body of the vehicle permits the tailgate to swing up for accessing the rear compartment of the vehicle. The tailgate may include a balancer mechanism such as but not limiting to gas balancer for selectively swinging the tailgate up, and retaining the same till the user closes the tail gate. Further, the fixed type of tail gates are removably attached to the rear part structure of the vehicle with the help of members such as but not limiting to fasteners. In the vehicles with fixed type tail gates the user can load the luggage from inside by folding the rear seat, or he has to unfasten the fasteners from inside to remove the tailgate to access the rear compartment of the vehicle. It is difficulty for the user to load the things or luggage from inside by folding the rear seat. Further it is also very inconvenient and sometimes difficult to always unfasten four bolts from inside if user wants to have quick access to rear opening of the vehicle.

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.
