The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0030] Reference below Figure 1-Figure 3 A trunk lid structure 10 for a vehicle according to an embodiment of the present application is described. The trunk lid structure 10 includes an outer panel, an inner panel 11, a hinge reinforcement plate 12, a door lock reinforcement plate 13 and a reinforcement portion 14. The inner panel 11 is connected to the outer panel. A first mounting area 111, a second mounting area 112 and a reinforcement area 113 are formed on the inner panel 11. The first mounting area 111 is located at one end of the inner panel 11 in the width direction and extends in the length direction. The second mounting area 112 is located in the middle of the inner panel 11 and is spaced apart from the first mounting area 111. The reinforcement area 113 is located between the first mounting area 111 and the second mounting area 112 and is arranged around the second mounting area 112. The hinge reinforcement plate 12 is arranged in the first mounting area 111, the door lock reinforcement plate 13 is arranged in the second mounting area 112, and the reinforcement portion 14 is arranged in the reinforcement area 113.

[0031] At present, the trunk lid sheet metal assembly usually uses a cavity formed by welding inner and outer panels to provide rigidity, but due to the limitations of shape and forming process, the volume of the cavity cannot be greatly increased. Therefore, the effect of improving the rigidity by increasing the cavity volume of the inner and outer panels is limited. In this regard, the trunk lid sheet metal assembly also uses hinge reinforcement plates and lock mounting plates after welding to provide higher rigidity locally. However, the reinforcement range of the hinge reinforcement plates and lock mounting plates is limited to the installation parts of the hinges and locks. The parts far away from the reinforcement plates cannot be strengthened, resulting in the trunk lid assembly's bending, torsional and corner rigidity being obviously insufficient.

[0032] like Figure 1-Figure 3 As shown, specifically, the trunk lid structure 10 includes an inner panel 11 and an outer panel (not shown in the figure), the outer panel can face the outside of the vehicle, the inner panel 11 can be arranged on the side of the outer panel facing the inside of the vehicle, and the inner panel 11 and the outer panel can be fixed by bonding, wherein the outer periphery of the inner panel 11 is formed with a surrounding bonding edge, and the bonding edge can be bonded and fixed to the outer panel.

[0033] The trunk lid structure 10 also includes a hinge reinforcement plate 12, a door lock reinforcement plate 13 and a reinforcement portion 14. A first installation area 111, a second installation area 112 and a reinforcement area 113 are formed on the inner panel 11. The first installation area 111 can be located at one end of the inner panel 11 in the width direction, and the first installation area 111 can extend in the length direction. The hinge reinforcement plate 12 can be arranged in the first installation area 111. The hinge reinforcement plate 12 can improve the overall strength in the first installation area 111 and the stiffness of the hinge installation point. The second installation area 112 can be located in the middle of the inner panel 11, and the second installation area 112 can be spaced apart from the first installation area 111. The door lock reinforcement plate 13 can be arranged in the second installation area 112. The door lock reinforcement plate 13 can improve the overall strength of the second installation area 112 and the stiffness of the door lock installation point.

[0034] The reinforcement area 113 may be located between the first installation area 111 and the second installation area 112, and the reinforcement area 113 may be arranged around the outer periphery of the second installation area 112, and the reinforcement portion 14 may be arranged in the reinforcement area 113, wherein the reinforcement portion 14 may be constructed as a reinforcement rib, and the overall strength of the reinforcement area 113 may be improved by providing the reinforcement portion 14, thereby ensuring that the area on the inner panel 11 except the hinge reinforcement plate 12 and the door lock reinforcement plate 13 can effectively improve the rigidity, thereby ensuring the overall rigidity of the inner panel 11. The length direction and width direction referred to in this application are both the length direction of the inner panel 11 and the width direction of the inner panel 11.

[0035] In short, the trunk lid structure 10 of the embodiment of the present application has an inner panel 11, a hinge reinforcement plate 12, a door lock reinforcement plate 13 and a reinforcement portion 14.

The hinge reinforcement plate 12 is arranged in the first installation area 111, the door lock reinforcement plate 13 is arranged in the second installation area 112, and the reinforcement portion 14 is arranged in the reinforcement area 113. By providing the reinforcement portion 14, the overall strength of the reinforcement area 113 can be improved, thereby ensuring that the areas on the inner panel 11 other than the first installation area 111 and the second installation area 112 can effectively improve the stiffness, thereby ensuring the bending, torsional and corner stiffness of the trunk lid assembly.

The first reinforcing ribs 141 and the second reinforcing ribs 142 are spaced a certain distance from the second installation area 112 to avoid the first reinforcing ribs 141 and the second reinforcing ribs 142 from interfering with the door lock reinforcement plate 13 and affecting the normal installation of the door lock reinforcement plate 13. In a specific embodiment, the first reinforcing ribs 141 and the second reinforcing ribs 142 can be spaced 5 mm from the door lock reinforcement plate 13. The use of the first reinforcing ribs 141 and the second reinforcing ribs 142 can omit the support plate structure in the prior art and reduce the investment in component molds.

[0037] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, a first protrusion 114 extending toward the outer panel may be formed in the second installation area 112, and at least a portion of the hinge reinforcement plate 12 can be connected to the first protrusion 114.

[0040] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, a third protrusion 116 extending toward the outer panel may be formed in the first mounting area 111, and the third protrusion 116 can abut against the outer panel. Specifically, a mounting groove is formed on the third protrusion 116, and a shock-absorbing expansion glue may be arranged in the mounting groove. The shock-absorbing expansion glue can absorb and disperse vibration energy, thereby effectively reducing the generation of vibration and noise, and the shock-absorbing expansion glue can withstand a certain amount of tension and pressure, thereby increasing the structural strength of the inner panel 11 and the outer panel, and the self-reinforcing rib 143 of the third reinforcing rib 143 can effectively reduce the vibration and noise.

[0043] In some embodiments of the present application, the inner panel 11 and the reinforcement 14 can be constructed as SMC composite materials.
