[0030] In order to enable those skilled in the art to better understand the technical solutions of this application, the following further elaborates on this application in conjunction with the accompanying drawings and specific embodiments.

[0031] In this article, the direction close to the inside of the luggage compartment assembly is defined as "inward".

[0032] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a specific embodiment of the luggage compartment assembly provided by this application.

[0033] This embodiment provides a luggage compartment assembly, including a bottom cover plate 1, a left side panel 2, a right side panel, and a rear seat backrest 3. The left side panel 2 and the right side panel are correspondingly provided with inwardly protruding protruding parts A. The bottom cover plate 1 is arranged between the two protruding parts A. Part of the rear seat backrest 3 is located at the front end of the bottom cover plate 1. There is a first gap between the rear seat backrest 3 and the bottom cover plate 1. Part of the rear seat backrest 3 is located at the front end of the protruding part A. There is a second gap between the rear seat backrest 3 and the protruding part A.

[0034] It further includes an occlusion structure 4. The occlusion structure 4 includes a first occlusion part 41 and two second occlusion parts 42. The first occlusion part 41 is located between the rear seat backrest 3 and the bottom cover plate 1 and is used to occlude the first gap. The second occlusion part 42 is located between the rear seat backrest 3 and the corresponding protruding part A, that is, the second occlusion part 42 is located at both ends of the first occlusion part 41 in the left-right direction, and the second occlusion part 42 is used to occlude the second gap.

[0035] In the luggage compartment assembly of this embodiment, the left side wall 2 and the right side wall are correspondingly provided with inwardly protruding protruding parts A, which are usually used to avoid the wheels. The bottom cover plate 1 is arranged between the two protruding parts A. In some vehicle models, the width of the rear seat backrest 3 in the left-right direction is greater than the width of the bottom cover plate 1 in the left-right direction. Therefore, a part of the middle area of the rear seat backrest 3 is located in front of the bottom cover plate 1, and a part of the areas at both left and right ends of the rear seat backrest 3 are located in front of the protruding part A. While a gap is generated between the rear seat backrest 3 and the bottom cover plate 1, a gap will also be generated between the rear seat backrest 3 and the protruding part A.

[0036] In order to more comprehensively eliminate the gaps existing in the luggage compartment assembly, the luggage compartment assembly of this embodiment is additionally provided with a first occlusion part 41 and two second occlusion parts 42. The first occlusion part 41 occludes the first gap formed between the rear seat backrest 3 and the bottom cover plate 1, and the second occlusion part 42 occludes the second gap formed between the rear seat backrest 3 and the protruding part A, ensuring seamless contact between the components that enclose to form the luggage compartment assembly, preventing the items inside the luggage compartment assembly from falling through the gaps under the rear seat and being unable to be taken out, and solving the problem of item falling; at the same time, preventing the floor sheet metal and the seat frame from being exposed, improving the quality and delicacy of the vehicle interior, and giving users a better usage experience.

[0037] In this embodiment, the first occlusion part 41 and the second occlusion part 42 adopt an integrally formed structure design, and the integral structure formed by the first occlusion part 41 and the two second occlusion parts 42 is defined as the occlusion part.

[0038] It can be understood that in practice, it is also feasible that the first occlusion part 41 and the second occlusion part 42 are split structures. At this time, the first occlusion part 41 and the second occlusion part 42 can be seamlessly butted, or the first occlusion part 41 and the second occlusion part 42 have an overlapping area in the left-right direction, ensuring that both the first gap and the second gap can be reliably occluded.

[0039] Of course, this embodiment adopts the integrally formed structure design of the first occlusion part 41 and the second occlusion part 42. On the one hand, it is convenient for processing and improves the forming efficiency of the occlusion structure 4; on the other hand, the surface of the occlusion structure 4 has no seams, with better consistency and a better user experience. In addition, since the occlusion part is an integral structure, its load-bearing performance is also better.

[0040] Please refer to Figure 1 and Figure 2 , Figure 2 for Figure 1 Cross-sectional view of the trunk assembly in the CC direction.

[0041] In this embodiment, the shielding structure 4 further includes a connecting portion 43 . The connecting portion 43 is disposed at the rear end of the first shielding portion 41 and connected to the bottom cover plate 1 .

[0042] Thus, in this embodiment, the shielding structure 4 is provided with a connecting portion 43, which is connected to the bottom cover plate 1 to fix the shielding structure 4, ensuring that the fixed position of the shielding structure 4 is reliable, so that the shielding structure 4 can more reliably play its shielding role.

[0043] Please refer to Figures 3-5 , Figure 3 for Figure 1 A diagram showing the trunk assembly with the rear seat backrest in its initial position; Figure 4 for Figure 1 A diagram showing the trunk assembly with the rear seat backrest in the reclining position; Figure 5 for Figure 1 Diagram of the trunk assembly with the rear seat backrests in the folded position.

[0044] In this embodiment, the rear seat back 3 is rotatably mounted on the vehicle body, the front end of the first shielding portion 41 is in contact with the rear seat back 3, the periphery of the second shielding portion 42 is in contact with the corresponding wall surface forming the second gap, and the first shielding portion 41 and the second shielding portion 42 can rotate around the connection between the first shielding portion 41 and the connecting portion 43.

[0045] Among them, the periphery of the second shielding portion 42 and the corresponding wall surfaces surrounding the second gap are in conflict, specifically, the front end of the second shielding portion 42 and the rear seat back 3 are in conflict, the rear end of the second shielding portion 42 and the protrusion A are in conflict, the left end portion of the second shielding portion 42 located on the left side is in conflict with the relative inner wall of the left side surround 2, and the right end portion of the second shielding portion 42 located on the right side is in conflict with the relative inner wall of the right side surround.

[0046] like Figures 3-5 As shown, the rear seat back 3 has at least an initial position state, a reclining position state and a folding position state. The reclining position state is the rear limit position of the rear seat back 3, and the folding position state is the front limit position of the rear seat back 3. The initial position state is between the reclining position state and the folding position state.

[0047] As described above, the rear seat backrest 3 is rotatably mounted on the vehicle body, that is, the angle of the rear seat backrest 3 is adjustable. In other words, the widths of the first gap and the second gap in the front-rear direction are variable. In order to adapt to the width change of the first gap and the second gap in the front-rear direction, in this embodiment, the front end of the first shielding portion 41 abuts against the rear seat backrest 3, and the front end of the second shielding portion 42 abuts against the rear seat backrest 3. Moreover, the first shielding portion 41 and the second shielding portion 42 can rotate around the connection portion between the first shielding portion 41 and the connection portion 43. After the angle of the rear seat backrest 3 changes, the front ends of the first shielding portion 41 and the second shielding portion 42 can slide along the rear surface of the rear seat backrest 3, avoiding interference of the shielding structure 4 with the movement of the rear seat backrest 3, and ensuring that after the angle of the rear seat backrest 3 changes, the front end of the first shielding portion 41 always abuts against the rear seat backrest 3, and the front end of the second shielding portion 42 always abuts against the rear seat backrest 3. Furthermore, it is ensured that the shielding structure 4 can play its shielding role more reliably.

[0048] As Figures 3-5 shown, when the rear seat backrest 3 is in the initial position state, the first shielding portion 41 and the second shielding portion 42 extend horizontally; during the process of the rear seat backrest 3 moving from the initial position state to the reclined position state, the first shielding portion 41 and the second shielding portion 42 are gradually bent downward; during the process of the rear seat backrest 3 moving from the initial position state to the folded position state, the first shielding portion 41 and the second shielding portion 42 are gradually bent upward. When the rear seat backrest 3 is in the folded position state, the first shielding portion 41 and the second shielding portion 42 are partially pressed above the rear seat backrest 3.

[0049] In practice, when the rear seat backrest 3 is in the initial position state, it is feasible for the first shielding portion 41 and the second shielding portion 42 to extend obliquely upward or obliquely downward from the rear end to the front end, which does not affect the realization of the above shielding function. Of course, when the rear seat backrest 3 is in the initial position state, the first shielding portion 41 and the second shielding portion 42 extend horizontally, and the shielding structure 4 is flush with the bottom cover plate 1, which has better consistency and a better user experience, and is a more preferred technical solution.

[0050] In practice, the shielding structure 4 is not limited to the above connection form. Specifically:

[0051] In the second embodiment, the rear end of the first shielding portion 41 is connected to the bottom cover plate 1, the front end of the first shielding portion 41 is connected to the rear seat backrest 3, the front end of the second shielding portion 42 is connected to the rear seat backrest 3, the rear end of the second shielding portion 42 is connected to the protruding portion A, and the left and right ends of the second shielding portion 42 abut against the opposite inner walls of the left side wall 2 or the right side wall.

[0052] In this way, both the front and rear ends of the shielding structure 4 are fixed, ensuring a seamless connection between the rear seat back 3 and the bottom cover 1, and between the rear seat back 3 and the raised portion A, thus preventing items from falling. In some vehicle models, the rear seat back 3 is rotatably mounted to the vehicle body, meaning that the widths of the first and second gaps vary in the fore-aft direction. In this case, the shielding structure 4 can be configured as a wave-like structure that folds in the fore-aft direction. The shielding structure 4 can deform in response to changes in the angle of the rear seat back 3 and the width of the first and second gaps, expanding or folding in the fore-aft direction. This allows for sufficient margin for the movement of the rear seat back 3 and prevents the shielding structure 4 from interfering with the movement of the rear seat back 3.

[0053] Of course, in order to leave enough margin for the movement of the rear seat backrest 3, the second embodiment has a larger size of the shielding structure 4 in the front-to-back direction and a high material cost. However, this embodiment adapts to the angle change of the rear seat backrest 3 through the rotational deformation of the shielding part, and the size of the shielding part in the front-to-back direction is reduced, which reduces the material cost and is a more preferred technical solution.

[0054] Further, if Figure 2 As shown, in this embodiment, the first shielding portion 41 and the second shielding portion 42 are made of flexible fabric, and support members 44 are pre-embedded inside the first shielding portion 41 and the second shielding portion 42 .

[0055] In practice, except for the support member 44, the other structures of the shielding structure 4 are made of flexible fabrics, that is, the connecting part 43 is also made of flexible fabrics. Specifically, the same carpet fabric as the bottom cover plate 1 can be used. In this way, after the shielding structure 4 is connected to the bottom cover plate 1, the consistency is better and the user experience is better.

[0056] Furthermore, by pre-embedding support members 44 inside the first shielding portion 41 and the second shielding portion 42, the structural strength of the first shielding portion 41 and the second shielding portion 42 can be improved, the bearing capacity of the first shielding portion 41 and the second shielding portion 42 can be improved, and the possibility of the shielding structure 4 being crushed by items inside the luggage compartment assembly can be reduced, so that the shielding structure 4 can more reliably perform its shielding function.

[0057] In this embodiment, the width of the support member 44 along the front-to-back direction ranges from 20 mm to 100 mm.

[0058] In practice, the width of the support member 44 along the front-to-back direction can be adaptively designed according to the widths of the first gap and the second gap. The larger the widths of the first gap and the second gap, the larger the width of the support member 44 along the front-to-back direction.

[0059] In practice, the length of the support member 44 in the left-right direction can be approximately equal to the length of the shielding portion, or the length of the support member 44 in the left-right direction can be slightly less than the length of the shielding portion, ensuring that the shielding portion has sufficient bearing capacity while preventing the support member 44 from being exposed.

[0060] In practice, the support member 44 can be made of a rigid material such as metal. In this embodiment, the support member 44 is made of a steel plate.

[0061] In practice, the support members 44 inside the first shielding portion 41 and the second shielding portion 42 can be an integral structure.

[0062] In addition, in practice, the material of the shielding structure 4 is not limited to the above implementation. For example, it is also feasible that the shielding structure 4 is made of hard plastic. A notch groove can be processed at the connection between the first shielding portion 41 and the connecting portion 43 so that the shielding structure 4 can rotate around the connection between the first shielding portion 41 and the connecting portion 43. At this time, it is not necessary to pre-embed the aforementioned support member 44.

[0063] Please continue to refer to Figure 2 , in this embodiment, the connecting portion 43 includes an upper connecting portion 431 and a lower connecting portion 432. The front ends of the upper connecting portion 431 and the lower connecting portion 432 are connected together. The upper connecting portion 431 is connected to the upper side wall of the bottom cover plate 1, and part of the lower connecting portion 432 is connected to the lower side wall of the bottom cover plate 1.

[0064] Specifically, in the direction from the front end to the rear end, the lower connecting portion 432 first extends vertically downward and then horizontally backward. The downward extending portion is attached to the front end wall of the bottom cover plate 1, and the horizontally extending portion is connected to the lower side wall of the bottom cover plate 1.

[0065] With the above settings, on the one hand, the upper connecting portion 431 and the lower connecting portion 432 are both connected to the bottom cover plate 1 at the same time, which can improve the connection reliability between the shielding structure 4 and the bottom cover plate 1; on the other hand, the lower connecting portion 432 is hidden below the upper connecting portion 431, making the interior of the luggage compartment assembly neater and improving the refinement of the vehicle interior.

[0066] In this embodiment, the upper connecting portion 431 covers the upper side wall of the bottom cover plate 1.

[0067] In this way, there is no seam on the upper surface of the bottom cover plate 1, and the bottom cover plate 1 and the shielding structure 4 form an integral structure visually, with better consistency and a better user experience.

[0068] As Figure 2 shown, a notch portion is provided on the lower side wall of the bottom cover plate 1. The notch portion penetrates the front end wall of the bottom cover plate 1, and part of the lower connecting portion 432 is connected inside the notch portion. The lower surface of the lower connecting portion 432 is flush with the lower surface of the bottom cover plate 1.

[0069] In this way, the lower connecting portion 432 does not need to occupy the dimensional height space, and the unevenness of the lower surface of the bottom cover plate 1 is avoided, ensuring the flatness of the lower surface of the bottom cover plate 1.

[0070] Define the width of the notch portion in the front-rear direction as the first width, and the width of the portion of the lower connecting portion 432 connected inside the notch portion in the front-rear direction as the second width. The first width is greater than the second width. As Figure 2 shown, in the connected state, there is a spacing between the rear end wall of the notch portion and the rear end wall of the lower connecting portion 432.

[0071] With the above settings, the notch portion has sufficient space in the front-rear direction to prevent the lower connecting portion 432 from exceeding the notch portion, ensuring the flatness of the lower surface of the bottom cover plate 1.

[0072] In practice, the upper connecting portion 431 and the upper side wall of the bottom cover plate 1 can be fixed by bonding, and the lower connecting portion 432 and the lower side wall of the bottom cover plate 1 can be fixed by bonding.

[0073] This application also provides a vehicle, including the aforementioned trunk assembly.

[0074] The vehicle of this application includes the aforementioned trunk assembly, and thus has the same technical effects as the aforementioned trunk assembly, which will not be elaborated here.

[0075] The above is only the preferred embodiment of this application. It should be noted that for those of ordinary skill in the art, without departing from the principle of this application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this application.
