[0034] See also Figure 1 and Figure 2As shown, an embodiment of the utility model provides a car tailgate hinge installation structure, which is used to install the car tailgate hinge 2 to connect the car tailgate, which is beneficial to improve the rigidity of the connection between the tailgate and the tailgate hinge 2 and improve the NVH performance of the car. The car tailgate hinge installation structure includes a top cover rear cross beam 1 for installing the tailgate hinge 2, an upper side panel 5 for supporting the top cover rear cross beam 1, an upper reinforcing plate 3 installed between the top cover rear cross beam 1 and the upper side panel 5, and a hinge reinforcing plate 4 installed between the upper side panel 5 and the upper reinforcing plate 3. It should be noted that the upper side panel 5 mentioned here can refer to the upper side panel of the inner panel of the C-pillar or a part thereof, and the upper reinforcing plate 3 can refer to the upper reinforcing plate of the C-pillar or a part thereof. In addition, the tailgate hinge 2, the upper reinforcing plate 3, the hinge reinforcing plate 4 and the upper side panel 5 are all arranged on the same side of the top cover rear cross beam 1. In this embodiment, the automobile back door hinge installation structure refers to the left top structure of the automobile body seen from the rear end of the automobile to the front end of the automobile.

[0035] In this embodiment, the rear cross beam 1 of the top cover is in the shape of a long strip and is arranged above the rear part of the automobile body. In order to stably install the tailgate hinge 2, a receiving groove 11 recessed toward the inside of the automobile body is provided at the end of the rear cross beam 1 of the top cover. The shape of the groove 11 is consistent with the outer shape of the tailgate hinge 2 in the extended state. When the tailgate hinge 2 is installed in the receiving groove 11, the top surface of the receiving groove 11 fits with the bottom surface of the tailgate hinge 2. At this time, the side wall of the receiving groove 11 has the function of limiting the movement of the tailgate hinge 2 in the length and width directions of the vehicle body. In addition, since the receiving groove 11 has a certain depth, the rear cross beam 1 of the top cover can accommodate the tailgate hinge 2 in the receiving groove 11, which not only reduces the assembly position of the tailgate hinge 2 in the height direction of the vehicle body, but also avoids the tailgate hinge 2 from interfering with adjacent components. It should be noted that, in the present embodiment, the two intersecting surfaces of the receiving groove 11 for fitting with the tailgate hinge 2 are in a step-like shape, which is compatible with the tailgate hinge 2 in a hinge-like shape.

[0036] Furthermore, in order to fasten the back door hinge 2, a mounting hole for cooperating with the hinge fastener 7 is provided on the accommodating groove 11, so as to facilitate the installation of the hinge fastener 7. The hinge fastener 7 mentioned here may refer to a fastening bolt and a nut. It should be noted that in order to strengthen the rigidity of the connection between the back door and the back door hinge 2 and avoid the situation of fixation failure due to the back door opening angle being too large or the accumulation of the frequency of use, the upper reinforcing plate 3 and the hinge reinforcing plate 4 are both provided with mounting holes that are compatible with the mounting holes on the top cover rear beam 1. In this way, when the back door hinge 2 is installed in the accommodating groove 11, the back door hinge 2 can be fixed on the top cover rear beam 1 through the fastening effect of the hinge fastener 7 that passes through the hinge reinforcing plate 4, the upper reinforcing plate 3 and the top cover rear beam 1 in sequence. This not only has a relatively stable supporting effect on the back door hinge 2 installed on the top cover rear beam 1, but also strengthens the rigidity of the connection, ensuring that the fixing effect meets the expected design.

[0037] See also Figure 2 and Figure 4 As shown, the hinge reinforcement plate 4 includes a top plate 41 for attaching to the upper reinforcement plate 3, and a plurality of side plates 42 connected to the edge of the top plate 41 and connected in sequence. It should be noted that the plurality of side plates 42 mentioned here refer to the plurality of side plates 42 connected in sequence. Figure 2 Preferably, the hinge reinforcement plate 4 is a semi-enclosed box-shaped structure, so that a first cavity 45 is formed between the hinge reinforcement plate 4 and the upper side panel 5. Please refer to Figure 3 and Figure 6 As shown, this cavity structure can not only prevent the transmission of airflow and noise or vibration in the medium and high frequency bands to the interior of the automobile body, but is also beneficial for inspecting and maintaining the deformation of the hinge reinforcement plate 4.

[0038] In this embodiment, in order to ensure the connection stability between the hinge reinforcement plate 4 and the upper side panel 5, an extension plate 43 is formed at the edge of the top plate 41 and the side plate 42 to increase the contact area between the two. Preferably, the extension plate 43 extends outward in a direction away from the top plate 41 and the side plate 42.

[0039] See also Figure 2 and Figure 4 As shown, the upper reinforcing plate 3 is plate-shaped, one end of which is arranged between the rear cross beam 1 of the roof and the hinge reinforcing plate 4, and is stepped, which matches the shape of the receiving groove 11; the other end is connected to the upper side panel 5. It should be noted that in order to further prevent the transmission of airflow and noise or vibration in the middle and high frequency bands to the interior of the automobile body, the upper reinforcing plate 3 and the upper side panel 5 form a second cavity 35, please refer to Figure 3 As shown, it is beneficial to improve the NVH performance of the car.

[0040] See also Figure 2and Figure 4 As shown, the upper side panel 5 is a T-shaped plate structure, including a first plate section 51 for connecting the upper side beam of the automobile, a second plate section 52 for connecting the upper reinforcement plate of the D-pillar, and a third plate section 53 for connecting the rear cross beam 1 of the roof and the hinge reinforcement plate 4. In order to ensure a more beautiful appearance of the whole vehicle, in this embodiment, the first plate section 51 and the second plate section 52 extend in opposite directions, and the third plate section 53 extends in a direction perpendicular to the first plate section 51 and the second plate section 52, which is beneficial to better show the streamline of the whole vehicle.

[0041] For the purpose of noise reduction and vibration isolation, in this embodiment, the first plate section 51, the second plate section 52 and the third plate section 53 are all in a groove shape, so that the upper side panel 5 is a three-way structure. Since the cavity structure can not only block the transmission of airflow and noise or vibration in the middle and high frequency bands to the interior of the automobile body, but also has space for accommodating smaller parts, preferably, the first plate section 51, the second plate section 52 and the third plate section 53 are respectively formed with a first connecting portion, a second connecting portion and a third connecting portion for forming a cavity with adjacent parts, and the first connecting portion, the second connecting portion and the third connecting portion are connected to each other.

[0042] In this embodiment, in order to further ensure the connection rigidity between the back door hinge 2 and the back door, the automobile back door hinge installation structure further includes a seal 6, which is filled between the upper reinforcement plate 3 and the hinge reinforcement plate 4.
