The reinforcing component 200 of the trunk lid provides a firm and strong mounting point for the connection between the lid main body of the trunk lid and the hinge, so as to ensure the connection performance of the hinge and the trunk lid. The automobile trunk cover can shake and shake in the opening and closing processes, and the automobile trunk cover can be bent and deformed. In the related art, the reinforcement assembly 200 is provided in a flat structure to cover the region of the inner panel 110 of the trunk lid of the automobile, and the bending rigidity of the trunk lid of the automobile is compensated by increasing the area and thickness of the reinforcement assembly 200. However, with the development of automotive technology, the design of the trunk lid of the automobile is gradually changed from the conventional design, for example, a rear lamp is disposed in the horizontal direction of the trunk lid of the automobile. Because the area occupied by the tail lamp is large, the structural influence on the automobile trunk cover is large, the structure of the automobile trunk cover at the position of the through type tail lamp is weaker, and the bending deformation of the automobile trunk cover easily causes the bending deformation or the breakage of the tail lamp. Since the related art reinforcing assembly 200 for a trunk lid of an automobile compensates for the limited bending rigidity of the trunk lid, the related art reinforcing assembly 200 has not been able to satisfy the higher demand.

In order to satisfy the higher requirement of the reinforcement assembly 200, please refer to fig. 1 to 5, the embodiment of the present invention discloses a reinforcement assembly 200 for a trunk lid of a vehicle, wherein the disclosed reinforcement assembly 200 is used for reinforcing the connection between the cover main body 100 and the hinge of the trunk lid of the vehicle.

When the reinforcement member 200 is provided, the through direction of the groove structure is set in a direction in which the trunk lid of the automobile is easily bent and deformed. The first and

second sidewalls

220 and 230 and the fixing substrate 210 may be fixedly connected. The end of the first sidewall 220 facing away from the fixed base plate 210 is provided with a first flange 240, the end of the second sidewall 230 facing away from the fixed base plate 210 is provided with a second flange 250, and the first flange 240 and the second flange 250 are used for connecting with the outer plate 120.

According to the application, the reinforcing component 200 is arranged to be of a structure comprising the fixed substrate 210, the first side wall 220 and the second side wall 230, so that the first side wall 220 and the second side wall 230 can be respectively connected to two opposite side edges of the fixed substrate 210, the first side wall 220 and the second side wall 230 form a groove structure, the bending rigidity of the reinforcing component 200 in the through direction of the groove structure can be improved, and the reinforcing component is not easy to bend in the through direction of the groove structure; the end of the first side wall 220, which is far away from the fixed base plate 210, is provided with the first flanging 240, and the end of the second side wall 230, which is far away from the fixed base plate 210, is provided with the second flanging 250, so that the fixed base plate 210 is connected with the inner plate 110, and under the condition that the first flanging 240 and the second flanging 250 are connected with the outer plate 120, the reinforcing component 200 not only can provide a more stable mounting point for the connection of the hinge on the inner plate 110, but also the reinforcing component 200 is connected between the inner plate 110 and the outer plate 120, so that the bending strength of the whole formed by the inner plate 110, the outer plate 120 and the reinforcing component 200 in the through direction of the groove structure is higher, thereby effectively improving the bending strength of the automobile trunk lid, and further avoiding the trunk lid from generating larger bending deformation in the opening and closing processes; the design of the first and

second flanges

240 and 250 also increases the area of the reinforcement assembly 200 connected to the outer panel 120, thereby enhancing the connection of the reinforcement assembly 200 to the outer panel 120.

In some embodiments, when the fixing base 210 is connected to the inner plate 110, it is necessary to connect the fixing base 210 to the inner plate 110 in a groove structure, and in order to facilitate the connection between the fixing base 210 and the inner plate 110, preferably, the first turned-up edge 240 may extend in a direction away from the second side wall 230, and the second turned-up edge 250 may extend in a direction away from the first side wall 220.

In some embodiments, the sides of the first and

second sidewalls

220 and 230 facing away from the fixing substrate 210 are close to each other, so that the groove structure gradually converges from the fixing substrate 210 toward the opening of the groove structure. Such a structure that gradually converges from the fixing substrate 210 toward the opening of the groove structure may also cause an obstacle when the fixing substrate 210 is connected to the inner plate 110 through the groove structure, and in order to facilitate the connection between the fixing substrate 210 and the inner plate 110, preferably, the fixing substrate 210 has a first axis perpendicular to the plate surface of the fixing substrate 210, and both the first sidewall 220 and the second sidewall 230 may be inclined with respect to the first axis, wherein the first sidewall 220 is inclined along a side away from the second sidewall 230, and the second sidewall 230 is inclined along a side away from the first sidewall 220.

If the first side wall 220 is inclined too much along the side facing away from the second side wall 230 and the second side wall 230 is inclined too much along the side facing away from the first side wall 220, the overall strength and bending rigidity of the reinforcement assembly 200 may not be satisfactory upon a large impact, and in order to allow the reinforcement assembly 200 to satisfy higher requirements, it is preferable that the first side wall 220 and the second side wall 230 are inclined at an angle of inclination of between 10 and 35 degrees with respect to the first axis. Setting the inclination angle of the first and

second sidewalls

220 and 230 to between 10 and 35 degrees with respect to the first axis provides a higher overall strength and bending stiffness of the reinforcement assembly 200.

The outer panel 120 is a part of the trunk lid of the automobile exposed to the outside, and the connection of the first flange 240 and the second flange 250 to the outer panel 120, if through the bolt connection, may cause the bolt to be exposed to the outside and affect the appearance.
