[0030] See also Figure 1 to Figure 2 Now, a reinforcing bracket provided by the utility model is described. A reinforcing bracket comprises a reinforcing bracket body 100, which is arranged on the outer side of the door inner panel 200 and located at the rear of the water cut; a plurality of first sunken platforms 111 are arranged from top to bottom on the front side of the reinforcing bracket body 100, and the first sunken platforms 111 protrude toward one side of the door inner panel 200 to form a first connecting end surface 1111; a plurality of second sunken platforms 121 are arranged from top to bottom on the rear side of the reinforcing bracket body 100, and the second sunken platforms 121 protrude toward one side of the door inner panel 200 to form a second connecting end surface 1211; at least one first connecting end surface 1111 located at the upper part of the reinforcing bracket body 100 and at least one second connecting end surface 1211 located at the upper part of the reinforcing bracket body 100 are respectively connected to the inner panel reinforcing plate 300, and the remaining first connecting end surfaces 1111 and second connecting end surfaces 1211 are respectively connected to the door inner panel 200.
[0031] The utility model provides a reinforcing bracket. Compared with the prior art, the reinforcing bracket body 100 is arranged on the outside of the door inner panel 200 and is located at the rear of the water cut.

At least one second sunken platform 121 located at the upper part is connected to the inner panel reinforcing plate 300 by means of the second connecting end surface 1211, and the remaining second sunken platforms 121 are connected to the door inner panel 200 by means of the second connecting end surface 1211. The utility model provides a reinforcing bracket, which is installed on the outside of the door inner panel 200 and located at the rear of the water cut, and is connected to the door inner panel 200 and the inner panel reinforcing plate 300 through the first connecting end surface 1111 of the first sink 111 and the second connecting end surface 1211 of the second sink 121, so that the door inner panel 200, the inner panel reinforcing plate 300 and the reinforcing bracket body 100 form an integral structure. By setting the reinforcing bracket, the structural strength of the rear of the water cut can be greatly improved, the structural rigidity of the large notch position of the inner panel can be enhanced, and the durability of the door system opening and closing and the door closing sound quality can be ensured.
[0032] The door inner panel 200 refers to a plate or component inside the door, located between the door outer panel and the interior trim panel, and is mainly used to strengthen the door structure, provide support and protect the internal fittings. The inner panel reinforcement plate 300 refers to a plate or component inside the door, located between the door outer panel and the door inner panel 200, and is mainly used to strengthen the structural strength of the door inner panel 200 and provide support. The water cut of the car is the rubber wiper strip on both sides of the inner and outer sides of the rising and falling lower edge of the door glass. The inner wiper strip is the inner water cut, and the outer wiper strip is the outer water cut. Under normal circumstances, the height of the inner water cut and the outer water cut are the same, and are collectively referred to as the car's water cut.
[0033] See also Figure 2 and Figure 3 The rear side of the reinforcing bracket body 100 is provided with a flange structure 130, and the flange structure 130 has a plurality of ear plates 131 arranged sequentially from top to bottom, and the plurality of ear plates 131 are connected to the door inner panel 200. The flange structure 130 is integrally formed with the reinforcing bracket body 100, and the flange structure 130 is also bent with the door inner panel 200, and the plurality of ear plates 131 are integrally formed on the outer side of the flange structure 130, and the width of the ear plate 131 decreases sequentially from the inside to the outside, and one end of the outer side of the ear plate 131 has an arc end, so as to ensure that the overall structural strength of the ear plate 131 is more stable.
[0034] See also Figure 2 and Figure 3 The end of the ear plate 131 protrudes toward the inner side of the vehicle door to form a third connection end face 1311, and the plurality of third connection end faces 1311 are respectively connected to the inner door panel 200. The end of the ear plate 131 is bent to form a third connection end face 1311 on the side of the ear plate 131 close to the inner side of the vehicle door, and a convex rib structure perpendicular to the fold is provided in the bending area of the ear plate 131, which can improve the structural strength of the bending area and reduce the deformation of the ear plate 131.
[0035] The width of the ear plate 131 itself is smaller than the distance between adjacent ear plates 131 to ensure that there is sufficient spacing between the ear plates 131, effectively avoiding large-area contact between the reinforcing bracket body 100 and the door inner panel 200, and improving the operating efficiency during the connection process.
[0036] In addition, a clearance is formed between the flange structure 130 and the unbent area of the ear plate 131 and the door inner panel 200. The clearance is generally set to about 5 mm, which can avoid interference between the reinforcing bracket body 100 and the door inner panel 200 during installation.
[0037] Preferably, the third connection end face 1311 is welded and fixed to the door inner panel 200. The door inner panel 200 is provided with a plurality of corresponding boss structures in the region corresponding to the plurality of third connection end faces 1311, and the boss structures have connection planes, and the plurality of third connection end faces 1311 are welded on the connection planes of the plurality of boss structures in a one-to-one correspondence. In addition, by providing the boss structures on the door inner panel 200, the structural strength and structural rigidity of the door inner panel 200 can also be improved, and the deformation tendency of the door inner panel 200 can be reduced. When the third connection end face 1311 is welded to the connection plane, if the ear plate 131 or the boss structure is thermally deformed, the above-mentioned clearance can provide deformation space for the ear plate 131 or the boss structure, so as to ensure the smooth progress of the above-mentioned welding and ensure the welding accuracy. At the same time, the welding part between the third connection end face 1311 and the door inner panel 200 is shielded by the sealing strip to prevent the welding point from leaking, so as to improve the aesthetics of the door.
[0038] For details, please refer to Figure 1 and Figure 3 There are four ear plates 131, among which the three lower ear plates 131 are spaced the same in between and are respectively welded to the connecting plane of the boss structure of the door inner panel 200, the distance between the uppermost ear plate 131 and the second uppermost ear plate 131 is greater than the distance between the lower three ear plates 131, and the uppermost ear plate 131 is directly welded to the connecting plane of the door inner panel 200.
[0039] See also Figure 1 and Figure 3, the first connection end face 1111 and the second connection end face 1211 are welded and fixed to the inner panel reinforcement plate 300 and the door inner panel 200 respectively. Specifically, at least one first connection end face 1111 located on the upper part of the reinforcement bracket body 100 and at least one second connection end face 1211 located on the upper part of the reinforcement bracket body 100 are welded and fixed to the inner panel reinforcement plate 300 respectively, and the remaining first connection end faces 1111 and second connection end faces 1211 are welded and fixed to the door inner panel 200 respectively. Similarly, the positions of the inner panel reinforcement plate 300 and the door inner panel 200 corresponding to the plurality of first connection end faces 1111 and the plurality of second connection end faces 1211 are also provided with connection planes, and the first connection end faces 1111 and the second connection end faces 1211 overlap with the corresponding connection planes and are welded and fixed. It effectively avoids the bracket from contacting with the door inner panel 200 and the inner panel reinforcement plate 300 over a large area, and at the same time improves the operation efficiency during the connection process, thereby ensuring the quality of the welding points and the overall accuracy of the door. At the same time, the sealing strip is used to shield the welding parts between the first connecting end surface 1111 and the second connecting end surface 1211 and the door inner panel 200 and the inner panel reinforcement plate 300 to prevent the welding points from leaking out, so as to improve the aesthetics of the door.
[0040] For details, please refer to Figure 1 and Figure 3 , the number of the first sinkers 111 is two, the upper first sinker 111 is located at the left corner of the reinforcing bracket body 100, the lower first sinker 111 is located at the lower middle area of the left side of the reinforcing bracket body 100, and the effective area of the first connecting end face 1111 formed by the lower first sinker 111 is larger than the effective area of the first connecting end face 1111 formed by the upper first sinker 111. The number of the second sinkers 121 is three, the upper second sinker 121 is located at the right corner of the reinforcing bracket body 100, and the lower two second sinkers 121 are sequentially arranged in the lower middle area of the right side of the reinforcing bracket body 100, and the effective area of the second connecting end face 1211 formed by the lower two second sinkers 121 is smaller than the effective area of the second connecting end face 1211 formed by the upper second sinker 121.
[0041] See also Figure 1 and Figure 2 The reinforcing bracket body 100 includes a first plate body 110 on the outside and a second plate body 120 on the inside. The first plate body 110 and the second plate body 120 are integrally formed and arranged at an angle so that the overall reinforcing bracket body 100 can be conformed to the outside of the door inner panel 200 and the inner panel reinforcing plate 300. In addition, a bending area is formed at the junction of the first plate body 110 and the second plate body 120, and the bending area has a transition fillet to reduce the internal stress of the bending area. Specifically, a plurality of first sinks 111 are arranged on a side of the first plate body 110 away from the second plate body 120, and a plurality of second sinks 121 are arranged on a side of the second plate body 120 away from the first plate body 110.

The triangular convex rib 122 is located in the middle and lower area of the second plate 120, one side of the triangular convex rib 122 coincides with the above-mentioned bending area, and the whole extends to the side of the second plate 120 where the second sink 121 is provided. The triangular convex rib 122 enhances the ability of the reinforcement bracket body 100 to resist deformation, thereby further ensuring the overall rigidity of the door.
[0043] In addition, a concave rib is transversely arranged on the upper portion of the second plate body 120 . The concave rib is located above the second plate body 120 , which can further enhance the structural strength of the second plate body 120 , thereby enhancing the structural rigidity of the entire reinforcing bracket body 100 .
[0044] Preferably, the reinforcing bracket body 100 is made of a steel plate with a thickness of 1 mm to 1.5 mm, and the thickness of the steel plate is preferably 1.2 mm. The local thickness may be appropriately thickened, but generally not more than 1.5 mm, to avoid increasing the vehicle's own weight.
