Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] like Figures 1 to 5 As shown, this invention provides a car trunk lid structure for use in automobiles, especially new energy vehicles. The trunk lid structure includes an inner trunk lid panel 8 and an outer trunk lid panel 9. The outer side of the inner trunk lid panel 8 and the inner side of the outer trunk lid panel 9 are bonded together to form an integral structure. A frame structure is formed on the side of the inner trunk lid panel 8, and the inner trunk lid panel 8 is bonded to the inner side of the outer trunk lid panel 9 through the frame structure. Specifically, the frame structure is provided with multiple reinforcing components, which form a symmetrical structure along the centerline of the frame structure, thereby improving the overall performance of the inner trunk lid panel 8 and the outer trunk lid panel 9. The car trunk lid structure provided by this invention, through structural improvements, enables the car trunk lid to meet the mechanical performance requirements of electric configurations. The mechanical performance of this trunk lid structure is basically consistent with that of a metal trunk lid, while having high process feasibility and reduced weight.

[0033] Preferably, in combination with the above schemes, such as Figures 1 to 5As shown, an inner panel is partially or entirely formed on the inner panel 8 of the trunk lid, and the inner panel partially or entirely forms a reinforcing structure; wherein, the inner panel 8 of the trunk lid includes a first inner panel 811 and a second inner panel 812, and a frame structure and reinforcing components are sandwiched on the side between the first inner panel and the second inner panel; further, the reinforcing components include a first hinge reinforcing plate 1, a second hinge reinforcing plate 2, and a lock reinforcing plate 3; wherein, the lock reinforcing plate 3 is embedded and fixedly fixed at the middle position of the lower end of the outer side of the first inner panel, and a first inlay groove is formed at the middle position of the lower end of the outer side of the first inner panel, and the lock reinforcing plate 3 is embedded in the first inlay groove, thereby being fixedly connected to the first inner panel; further, the first hinge reinforcing plate 1 is embedded and fixedly disposed on the left side of the outer side of the first inner panel. And extends to the lock reinforcement plate 3; a second inlay groove is formed on the left side of the outer side of the first inner plate, and the first hinge reinforcement plate 1 is embedded in the second inlay groove, thereby being fixedly connected to the first inner plate; further, the second hinge reinforcement plate 2 is inlaid and fixedly disposed on the right side of the outer side of the first inner plate, and extends to the lock reinforcement plate 3; a third inlay groove is formed on the right side of the outer side of the first inner plate, and the second hinge reinforcement plate 2 is embedded in the third inlay groove, thereby being fixedly connected to the first inner plate; specifically, the first hinge reinforcement plate 1 and the second hinge reinforcement plate 2 are symmetrical along the centerline of the first inner plate 811, improving the overall performance; adopting the above scheme, the first hinge reinforcement plate 1, the second hinge reinforcement plate 2 and the lock reinforcement plate 3 are inlaid and fixedly disposed on the first inner plate, such as Figure 6 and Figure 7 As shown, through CAE analysis and comparison, the process of this inlay structure greatly helps to improve the mode and stiffness of the car trunk lid. The overall stiffness mode of the car trunk lid is improved by 4-5 Hz, and the stiffness value is basically the same as that of the metal trunk lid, which can meet the requirements of the current personalized design of car trunk lids.

[0034] Preferably, in combination with the above schemes, such as Figures 1 to 5 As shown, the frame structure includes a first crossbeam 4, a second crossbeam 5, a first longitudinal beam 6, and a second longitudinal beam 7. The first crossbeam 4 is transversely positioned on the left side of the outer surface of the first inner panel and connected to the locking reinforcement plate 3. The second crossbeam 5 is transversely positioned on the right side of the outer surface of the first inner panel and connected to the locking reinforcement plate 3. Specifically, the first crossbeam 4 and the second crossbeam 5 are symmetrical along the centerline of the first inner panel 811. Further, the first longitudinal beam 6 is longitudinally positioned on the left side of the outer surface of the first inner panel and connected to the junction of the first crossbeam 4 and the locking reinforcement plate 3. The second longitudinal beam 7 is longitudinally positioned on the right side of the outer surface of the first inner panel and connected to the junction of the second crossbeam 5 and the locking reinforcement plate 3. The first longitudinal beam 6 and the second longitudinal beam 7 are symmetrical along the centerline of the first inner panel 811, thereby improving the overall stability of the car trunk lid.

[0035] Preferably, in combination with the above schemes, such as Figures 1 to 5As shown, one end of the first longitudinal beam 6 connects to the first crossbeam 4 and the locking reinforcement plate 3, forming a V-shaped structure with the first crossbeam 4; the other end of the first longitudinal beam 6 extends above the left taillight of the car; one end of the second longitudinal beam 7 connects to the second crossbeam 5 and the locking reinforcement plate 3, forming a V-shaped structure with the second crossbeam 5; the other end of the second longitudinal beam 7 extends above the right taillight of the car; adopting the above-mentioned V-shaped structure design, the first longitudinal beam 6 and the second longitudinal beam 7 are designed at the junction of the first crossbeam 4, the second crossbeam 5 and the locking reinforcement plate 3, and extend to the top of the movable taillight of the car, forming a double V-shaped beam to strengthen the inner plate structure. This makes the plastic trunk lid itself have strong stiffness modes and mechanical properties, meets the electric opening and closing force, and can withstand the maximum load brought by the electric strut.

[0036] Preferably, in combination with the above schemes, such as Figures 1 to 5 As shown, the frame structure is preferably designed as a quadrilateral frame structure. Specifically, a first buffer block 81 is provided at the first corner of the quadrilateral frame structure, a second buffer block 82 is provided at the second corner, a third buffer block 83 is provided at the third corner, and a fourth buffer block 84 is provided at the fourth corner. Specifically, the first buffer block 81, the second buffer block 82, the third buffer block 83, and the fourth buffer block 84 are clamped between the first inner panel 811 and the second inner panel 812, and can limit the inner panel 8 of the trunk lid, thereby playing a limiting role. With the above scheme, the buffer blocks designed at the four corner positions can better constrain the plastic trunk, improve the overall vehicle mode, and effectively solve the problem of abnormal noise during later road tests.

[0037] Preferably, in combination with the above schemes, such as Figures 1 to 5 As shown, the inner panel 8 of the luggage compartment lid has multiple protrusions on its outer side, and the outer panel 9 of the luggage compartment lid has a groove on its inner side. Structural adhesive is applied to the outer end face of the protrusions for bonding and fixing. Furthermore, the inner panel 8 of the luggage compartment lid is engaged with the groove by the protrusions and bonded to the groove by structural adhesive, thus fixing it to the outer panel 9 of the luggage compartment lid. Specifically, the adhesive application area of ​​the protrusions is 15mm wide, and the structural adhesive is a two-component polyurethane adhesive. The inner panel 8 and the outer panel 9 of the luggage compartment lid are bonded and pressed together using the two-component polyurethane adhesive. Using the above method, the protrusion structure is coated with structural adhesive and bonded to the outer panel of the luggage compartment lid, thus strengthening areas of weakness and poor dent resistance in the outer panel.

[0038] Preferably, in combination with the above schemes, such as Figures 1 to 5As shown, the multiple protrusions include a first protrusion 85, a second protrusion 86, a third protrusion 87, a fourth protrusion 88, a fifth protrusion 89, and a sixth protrusion 810. The first protrusion 85 is located at the upper left side of the outer side of the inner panel 8 of the trunk lid, the second protrusion 86 is located at the middle of the upper part of the outer side of the inner panel 8 of the trunk lid, the third protrusion 87 is located at the upper right side of the outer side of the inner panel 8 of the trunk lid, the fourth protrusion 88 is located at the lower right side of the outer side of the inner panel 8 of the trunk lid, the fifth protrusion 89 is located at the middle of the lower part of the outer side of the inner panel 8 of the trunk lid, and the sixth protrusion 810 is located at the lower left side of the outer side of the inner panel 8 of the trunk lid. By using the above solution, by designing protruding structures at six positions on the outer side of the inner panel 8 of the trunk lid and bonding them with adhesive, the connection stability between the inner panel 8 of the trunk lid and the outer panel 9 of the trunk lid can be effectively improved.

[0039] Preferably, in combination with the above schemes, such as Figures 1 to 5 As shown, the inner panel 8 of the trunk lid is made of PP (polypropylene) and LGF40 materials, while the outer panel 9 is made of PP+EPDM-T30 materials. The plastic trunk lid process is highly feasible, and compared to metal trunk lids, it is lighter and cheaper, thus contributing approximately 22% to the overall vehicle cost reduction. Furthermore, the reinforcing components are made of metal, and the frame structure also incorporates fiberglass straps 11. Multiple metal reinforcing components are connected together by these fiberglass straps 11. These straps connect the metal reinforcing components in the inner panel 8 of the trunk lid, preventing internal metal parts from flying and injuring pedestrians when the trunk lid breaks upon impact, thus providing a safety function. Moreover, the fiberglass strap 11 material is recyclable, highly malleable, processable, heat-resistant, and low-density, contributing to the overall vehicle cost reduction (providing approximately 22% weight reduction) and improving the range of new energy electric vehicles.

[0040] Preferably, in combination with the above schemes, such as Figures 1 to 5 As shown, the luggage compartment lid outer panel 9 includes an upper outer panel 91, a middle outer panel 92, and a lower outer panel 93; the upper outer panel 91 and the middle outer panel 92 are welded together, and the middle outer panel 92 and the lower outer panel 93 are welded together to form the luggage compartment lid outer panel 9. By adopting the above connection method, the mechanical performance requirements of the electric luggage compartment lid and the stiffness mode of the plastic luggage lid itself can be met; furthermore, a sealing strip is also provided on the frame structure. The sealing strip is set on the side of the first hinge reinforcing plate 1 and the second hinge reinforcing plate 2, thereby achieving a seal between the first inner panel and the second inner panel and reducing noise.

[0041] Accordingly, in conjunction with the above schemes, such as Figures 1 to 5As shown, the present invention also provides an automobile, preferably a new energy vehicle; specifically, the new energy vehicle includes a trunk lid structure and a drive mechanism 10, wherein the trunk lid structure is the automobile trunk lid structure described above; further, the drive mechanism 10 is mounted on the vehicle frame and connected to the trunk lid structure through a transmission mechanism, thereby enabling the trunk lid structure to open or close; further, the drive mechanism 10 is an electric drive mechanism; by adopting the above-described trunk lid structure scheme, the free mode, torsional stiffness, bending stiffness, lateral stiffness, side stiffness, fatigue value, and opening / closing performance requirements of the trunk lid under the electric drive mechanism can be met, making the trunk lid itself stronger in stiffness mode and mechanical properties, able to meet the electric opening and closing force, and able to withstand the maximum load brought by the electric strut.

[0042] This invention provides a car trunk lid structure and a car, which brings lightweight benefits to the whole vehicle, enabling the mechanical properties of the plastic trunk lid (plastic material is relatively soft) to reach the performance targets of traditional metal trunk lids. The plastic trunk lid has high plasticity and can meet more needs of the overall vehicle styling (current dynamic and youthful styling is difficult to achieve with the process of metal trunk lids).

[0043] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention.
