The subject matter in general relates to a backdoor assembly of an
automobile. More particularly, but not exclusively, the subject matter relates to dampening of vibrations in the backdoor assembly of the automobile.
BACKGROUND
[002] Background description includes information that may be useful in
understanding the present subject matter. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed subject matter, or that any publication specifically or implicitly referenced is prior art.
[003] In the current design of backdoor, in order to provide better aesthetics,
a tail lamp is positioned at the center of the backdoor and construction of the tail lamp is such that it is connected end to end of the backdoor. Conventionally, the backdoor assembly comprises an inner panel and an outer panel, wherein the two panels are connected to each other at their outer edges and around rear glass region.
[004] The design of the backdoor is mainly dependent on its construction of
mountings which are an integral part of the backdoor. The mountings are mainly used for mounting license plate, spoiler, tail lamp, garnish, among others. These mountings produce unwanted vibrations during vehicular movement. Also, vibrations are produced during the opening and closing of the backdoor. Since, the two panels in the backdoor are only connected to each other at their outer edges and around back glass region, these vibrations are not absorbed effectively which result in degraded experience to the occupants inside vehicle cabin.

[0037] Referring to FIGs. 1 and 2, disclosed is a backdoor assembly 100 of an automobile. The backdoor assembly 100 comprises an outer panel 202 and an inner panel 204.
[0038] FIGs. 3 A and 3B disclose isometric views of a reinforcement bracket 300, in accordance with an embodiment of the present disclosure. The reinforcement bracket 300 is configured to connect the outer panel 202 to the inner panel 204 of the backdoor assembly 100 of the automobile. In an aspect, two reinforcement brackets 300 are placed at equal distance on each side from the central line of the backdoor assembly 100. The reinforcement bracket 300 comprises a main body 302, a first leg 308, a second leg 310, a first connecting part
Page 7 of 15

312 and a second connecting part 314.
[0039] The main body 302 comprises a first portion 304 and a second portion 306. The first portion 304 and the second portion 306 are at an angle to each other. In an embodiment, both the first portion 304 and the second portion 306 are along a same plane. Longitudinal axis 328 of the first portion 304 and longitudinal axis 330 of the second portion 306 are not along the same line so as to form an angle between the first portion 304 and the second portion 306.
[0040] In an embodiment, the angle formed between the first portion 304 and the second portion 306 is greater than 90 degrees but less than 180 degrees.
[0041] In an embodiment, the first portion 304 and the second portion 306 of the main body 302 is in the shape of a boomerang.
[0042] In an embodiment, a portion 326 of the main body 302 is configured to connect the reinforcement bracket 300 with the outer panel 202. The portion 326 of the main body 302 being connected to the outer panel 202 is the intersection region of the first portion 304 and the second portion 306.
[0043] In an embodiment, the portion 326 of the main body 302 is connected to the outer panel 202 using a sealant or an adhesive.
[0044] In an embodiment, the first leg 308 is connected to the first portion 304 through the first connecting part 312 and the second leg 310 is connected to the second portion 306 through the second connecting part 314.
[0045] In an embodiment, the main body 302, the first leg 308, the second leg 310, the first connecting part 312, and the second connecting part 314 together forms a boomerang hat shaped structure of the reinforcement bracket 300.
[0046] In an embodiment, the first leg 308 and the second leg 310 of the reinforcement bracket 300 are connected to the inner panel 204 of the backdoor assembly 100.
Page 8 of 15

[0047] In an embodiment, the first portion 304 comprises a bead structure 322. The bead structure is along the longitudinal axis 328 and extends to the first connecting part 312.
[0048] In an embodiment, the second connecting part 314comprises a bead structure 322.
[0049] In an embodiment, the bead structure 322 provides rigidity and stiffness to the reinforcement bracket 300.
[0050] In an embodiment, one of the first leg 308 and the second leg 310 defines a step portion 320. The step portion 320 comprises a first step 316 and a second step 318. The first step 316 and the second step 318 are in two different planes.
[0051] In an embodiment, the first leg 308 and the second leg 310 are spot welded to the inner panel 204 at points 324.
[0052] In an embodiment, the spot weld points 324 in the second leg 310 comprising the step portion 320 are in a zig zag manner.
[0053] In an embodiment, the width of the first leg 308, the first connecting part 312 and the main body 302 is constant. The width of the second connecting part 314 widens towards the second leg 310. The widening of the second connecting part 314 also widens the width of the second leg 310 when compared to the first leg 308.
[0054] In an alternate embodiment, the first leg 308 comprises the step portion 320 and all the corresponding features as discussed in the above embodiment with the second leg 310 comprising the step portion 320.
[0055] FIG. 4 discloses a cross sectional view of the reinforcement bracket 300 with the first leg 308 in contact with the backdoor assembly 100, in accordance with an embodiment.
Page 9 of 15

[0056] FIG. 5 discloses a cross sectional view of the reinforcement bracket 300 with the second leg 310 in contact with the backdoor assembly 100, in accordance with an embodiment.
[0057] In an embodiment, there are two reinforcement brackets 300 provided in-between the outer panel 202 and the inner panel 204. The two reinforcement brackets 300 are placed at equal distance on each side from the central line of the backdoor assembly 100.
[0058] In an embodiment, the two reinforcement brackets 300 are disposed such that the second legs 310 of the two reinforcement brackets 300 are closer to each other than the first legs 308 of the two reinforcement brackets 300.
[0059] In an embodiment, in the event of vibrations being generated in the backdoor assembly 100, the main body 302 of the reinforcement bracket 300 transmits these vibrations to the inner panel 204 through the legs 310, 308, thereby distributing the localised vibrations over a larger area. The reinforcement bracket 300 connects the outer panel 202 and inner panel 204 more rigidly due to which the overall stiffness of the backdoor assembly 100 is enhanced. This improves the durability of the backdoor and dampens the vibrations.
