The luggage compartment panel and the rear frame assembly are used together to form a luggage compartment for storing luggage. The luggage compartment panel includes a first luggage panel section, a luggage transition section, and a second luggage panel section. The luggage compartment panel is generally L-shaped to increase the luggage compartment volume. It is precisely because of the L-shaped structure of the luggage compartment panel that the luggage transition section is a structurally weak area.

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0054] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0055] This application provides a luggage floor assembly, in one embodiment, referring to... Figures 1 to 3 , Figure 1 This is a perspective structural diagram of an embodiment of the luggage compartment floor assembly provided in this application. Figure 2 yes Figure 1 An exploded 3D diagram of the luggage compartment floor assembly. Figure 3 yes Figure 1 A top view structural plan of the trunk floor assembly, which includes a rear frame assembly 30, a trunk panel 20, and a reinforcing member 10; the trunk panel 20 is connected to the rear frame assembly 30 and extends along the width direction Y of the vehicle; the trunk panel 20 includes a first trunk panel portion 21, a trunk transition portion 23, and a second trunk panel portion 22 arranged sequentially along the length direction X of the vehicle; the first trunk panel portion 21 and the second trunk panel portion 22 are arranged at an angle; the trunk transition portion 23 connects the first trunk panel portion 21 and the second trunk panel portion 22; the reinforcing member 10 is connected to the trunk panel 20 and at least covers the trunk transition portion 23; the reinforcing member 10 extends along the width direction Y of the vehicle.

[0056] The rear frame assembly 30 serves as the basic support structure. It can be a single-piece cast structure with high structural strength. Its material can be, but is not limited to, magnesium alloy or aluminum alloy. This design helps ensure the overall strength of the floor while also contributing to its lightweight nature and ease of die-casting. Typically, the rear frame assembly 30 is a closed-loop frame structure, with the rear floor panel connected to its inner side, forming a complete support surface.

[0057] The luggage compartment panel 20 is used together with the rear frame assembly 30 to form a luggage compartment for storing luggage. The luggage compartment panel 20 is a large-area panel and can be made of high-strength alloy materials. Specifically, the luggage compartment panel 20 can be made of aluminum alloy, carbon fiber or steel to withstand high impact forces.

[0058] The luggage compartment panel 20 consists of three parts: a first luggage compartment panel 21 and a second luggage compartment panel 22 are arranged at an angle and connected by a luggage transition section 23, forming an "L"-shaped panel. This "L"-shaped structure allows the luggage compartment panel 20, together with the rear frame assembly 30, to form a luggage compartment with a large volume, while also absorbing collision energy. In some embodiments, the angle between the first luggage compartment panel 21 and the second luggage compartment panel 22 is equal to or slightly greater than 90 degrees. For example, the first luggage compartment panel 21 can be parallel to or at an angle relative to the vehicle's height direction Z, and the second luggage compartment panel 22 can be parallel to the vehicle's length direction X. In a preferred embodiment, the first luggage compartment panel 21 is at an angle relative to the vehicle's height direction Z, such that the angle between the first luggage compartment panel 21 and the second luggage compartment panel 22 is greater than 90 degrees, allowing the collision force to be transmitted more smoothly from the luggage compartment panel 20 to the rear frame assembly 30.

[0059] The reinforcing member 10 is an independent component attached to the luggage compartment panel 20. It can be fixed to the luggage compartment panel 20 by welding or screwing. The reinforcing member 10 is an elongated component extending along the width direction Y of the vehicle, used to strengthen the structural strength of the luggage compartment panel 20. Since the reinforcing member 10 at least covers the luggage transition section 23, it can strengthen the structural strength of the root region of the luggage compartment panel 20. The root region of the luggage compartment panel 20 can be understood as the area adjacent to the luggage transition section 23, including the first luggage panel section 21 and the second luggage panel section 22. Due to the "L"-shaped structure of the luggage compartment panel 20, the luggage transition section 23 is a structurally weak area. The reinforcing member 10 can strengthen this weak area, specifically creating a stress-dispersing geometry in the weak root region of the luggage compartment panel 20, thereby improving the structural and collision performance of the luggage compartment panel 20. Among them, the reinforcing member 10 can be made of hot-formed steel plate, so that the reinforcing member 10 has high structural strength and its reinforcement effect on the weak areas of the luggage compartment panel 20 is better.

[0060] The meaning of "the reinforcement 10 at least covers the baggage transition section 23" is that the reinforcement 10 may only cover the baggage transition section 23, or it may extend to cover the area of ​​the first baggage panel 21 adjacent to the baggage transition section 23, or it may extend to cover the area of ​​the second baggage panel 22 adjacent to the baggage transition section 23.

[0061] The luggage floor assembly provided in this application includes a rear frame assembly 30, a luggage panel 20, and a reinforcing member 10. The luggage panel 20 and the rear frame assembly 30 are used together to form a luggage compartment for storing luggage. The luggage panel 20 includes a first luggage panel portion 21, a luggage transition portion 23, and a second luggage panel portion 22. The luggage panel 20 is generally L-shaped to increase the luggage compartment volume. Due to the L-shaped structure of the luggage panel 20, the luggage transition portion 23 is a structurally weak area. The reinforcing member 10 at least covers the luggage transition portion 23 to strengthen the structural strength of the luggage panel 20 in the luggage transition portion 23. By adding a structural reinforcing member separately to the luggage transition portion 23 of the luggage panel 20, this application can effectively improve the strength of the entire frame structure of the luggage floor assembly, and at the same time, it can also effectively improve the collision performance of the entire frame structure.

[0062] Please see Figures 4 to 6 , Figure 4 yes Figure 3 Schematic diagram of section AA in the middle. Figure 5 yes Figure 4 Enlarged view within the dashed circle. Figure 6 yes Figure 3 A schematic diagram of the BB cross section shows that in some embodiments, the reinforcing member 10 and the luggage compartment panel 20 together define the root reinforcing cavity 40.

[0063] In this embodiment, the reinforcing member 10 and the trunk panel 20 together construct the root reinforcing cavity 40. This root reinforcing cavity 40 can absorb collision energy on the one hand, and enhance the rigidity of the root area of ​​the trunk panel 20 on the other hand. This allows the impact force during a rear-end collision to be evenly transmitted to the rear frame assembly 30 through the reinforcing cavity 40, improving the overall structural resistance to deformation. The root reinforcing cavity 40 formed by the "L"-shaped trunk panel 20 and the reinforcing member 10 maintains the original volume requirements of the trunk while enhancing the structural strength and collision performance of the trunk panel 20.

[0064] Please see Figure 7 and Figure 8 , Figure 7 yes Figure 2 A schematic diagram of the planar structure of the central reinforcement member. Figure 8 yes Figure 2 A three-dimensional structural schematic diagram of the middle reinforcement member. In some embodiments, the root reinforcement cavity 40 is defined by the luggage compartment panel 20 and the protrusion 102 of the reinforcement member 10. The protrusion 102 protrudes in the direction away from the luggage compartment panel 20 compared to other parts of the reinforcement member 10, which facilitates the formation of the root reinforcement cavity 40. Since the root reinforcement cavity 40 is usually a cavity with a relatively small volume, it will not occupy too much space or affect the original volume of the luggage compartment.

[0065] In some embodiments, the root reinforcement cavity 40 is a single cavity that can extend along the width direction Y of the vehicle, so that the collision energy can be transmitted along the length direction of the root reinforcement cavity 40, which is the width direction Y of the vehicle.

[0066] In other embodiments, the root reinforcement cavity 40 consists of multiple cavities spaced apart from each other. By setting up multiple cavities, the collision energy absorption effect can be further improved, thereby further improving the collision performance.

[0067] In some embodiments, the reinforcement 10 extends from one side of the trunk panel 20 to the other side of the trunk panel 20; the root reinforcement cavity 40 extends from one side of the trunk panel 20 to the other side of the trunk panel 20 along the width direction Y of the vehicle.

[0068] Along the width direction Y of the vehicle, the two ends of the reinforcing member 10 can be flush with the two ends of the luggage compartment panel 20, and the two ends of the root reinforcing cavity 40 can be flush with the two ends of the luggage compartment panel 20, or adjacent to the two ends of the luggage compartment panel 20.

[0069] In this embodiment, the reinforcing member 10 penetrates both sides of the trunk panel 20 to form a continuous support structure, and the root reinforcing cavity 40 also penetrates both sides of the trunk panel 20, which can effectively improve the compressive strength and deformation resistance of the root area of ​​the trunk panel 20. The reinforcing member 10 and the root reinforcing cavity 40 penetrating both sides of the trunk panel 20 can form a continuous mechanical support system along the width direction Y of the vehicle, so that the rear collision energy is more evenly transferred to the rear frame assembly 30, thereby improving the overall collision performance.

[0070] In some embodiments, the cross-section of the root reinforcement cavity 40 may be rectangular or other closed cross-sections.

[0071] In some embodiments, see again Figure 8 The reinforcing member 10 includes a central region 11 and an edge region 12. The edge region 12 is disposed around the central region 11 and is fixedly attached to the luggage compartment panel 20. At least a portion of the central region 11 is spaced apart from the luggage compartment panel 20 to form a root reinforcing cavity 40.

[0072] The edge region 12 refers to the circumferential edge of the luggage compartment panel 20, and the edge region 12 can be a closed annular region. The central region 11 refers to the region of the reinforcing member 10 radially inward of the edge region 12. The reinforcing member 10 is fixed to the luggage compartment panel 20 by fitting the edge region 12, thus achieving a fixed connection between the reinforcing member 10 and the luggage compartment panel 20. Figure 8 The gray area represents the central region 11.

[0073] The meaning of "at least a portion of the middle region 11 is spaced apart from the baggage transition section 23 to form the root reinforcing cavity 40" is that the entire middle region 11 can be spaced apart from the baggage transition section 23 to form the root reinforcing cavity 40, in which case the root reinforcing cavity 40 is a single elongated cavity; or a portion of the middle region 11 can be spaced apart from the baggage transition section 23 to form the root reinforcing cavity 40, while another portion is fitted and fixed to the baggage transition section 23, in which case the root reinforcing cavity 40 forms multiple spaced small cavities.

[0074] The area where the edge region 12 and the luggage compartment panel 20 are attached can be fixed together by means of, but not limited to, laser welding.

[0075] Specifically, the edge region 12, which is in contact with the trunk panel 20, includes two first edge regions 121 located on both sides in the width direction Y of the vehicle and two second edge regions 122 located on both sides in the length direction X of the vehicle.

[0076] In some embodiments, one second edge region 122 is only attached to and fixed to the area of ​​the first luggage panel 21 adjacent to the luggage transition portion 23, and the other second edge region 122 is only attached to and fixed to the area of ​​the second luggage panel 22 adjacent to the luggage transition portion 23. In this structure, the root reinforcing cavity 40 may only cover the luggage transition portion 23, or it may extend from covering the luggage transition portion 23 to covering the area of ​​the first luggage panel 21 adjacent to the luggage transition portion 23, and from covering the luggage transition portion 23 to covering the area of ​​the second luggage panel 22 adjacent to the luggage transition portion 23. In other embodiments, both second edge regions 122 are only attached to and fixed to the luggage transition portion 23. In still other embodiments, one second edge region 122 extends further from being attached to and fixed to the luggage transition portion 23 to being attached to and fixed to the area of ​​the first luggage panel 21 adjacent to the luggage transition portion 23, and the other second edge region 122 extends further from being attached to and fixed to the luggage transition portion 23 to being attached to and fixed to the area of ​​the second luggage panel 22 adjacent to the luggage transition portion 23.

[0077] The protrusion 102 in the above embodiment may be a part of the central region 11.

[0078] In some embodiments, the luggage transition portion 23 is arc-shaped and has concave and convex surfaces facing away from each other, with the reinforcing member 10 located on the side of the concave surface away from the convex surface.

[0079] The radius of curvature of the baggage transition section 23 can be adjusted according to the force requirements, and the baggage transition section 23 can have a constant curvature or a non-constant curvature.

[0080] In this embodiment, the arc-shaped design of the luggage transition section 23 makes the stress distribution more uniform and avoids stress concentration at sharp corners. The structural layout of the reinforcing member 10, located on the concave side of the luggage transition section 23 away from the convex side, effectively improves the bending strength of the base area of ​​the luggage compartment panel 20. This structural design, in the event of a collision, can more evenly transfer the impact force to the rear frame assembly 30 through the arc-shaped feature of the luggage transition section 23 and the supporting effect of the reinforcing member 10, significantly improving the structural strength and collision safety of the base area of ​​the luggage compartment panel 20. In other embodiments, the reinforcing member 10 is also located on the convex side away from the concave side.

[0081] Corresponding to the arc shape of the baggage transition section 23, the first edge region 121 of the reinforcing member 10 is also arc-shaped to better fit the arc shape of the baggage transition section 23. Specifically, the arc-shaped convex surface of the first edge region 121 has the same shape as the arc-shaped concave surface of the baggage transition section 23 to achieve a complete fit between the two.

[0082] Meanwhile, considering that the luggage transition section 23 is arc-shaped, in order to achieve a better fit and fixation effect between the elongated second edge region 122 and the luggage compartment panel 20, and a better support effect of the reinforcing member 10 on the root region of the luggage compartment panel 20, in a preferred embodiment, one of the second edge regions 122 is only fitted and fixed to the area of ​​the first luggage panel 21 adjacent to the luggage transition section 23, and the other second edge region 122 is only fitted and fixed to the area of ​​the second luggage panel 22 adjacent to the luggage transition section 23. In this way, on the one hand, the root reinforcing cavity 40 can have a relatively large cavity volume, thereby improving the collision energy absorption effect, and on the other hand, it can also improve the fit and fixation effect between the second edge region 122 and the luggage compartment panel 20.

[0083] In some embodiments, see also Figures 7 to 9 , Figure 9 yes Figure 7 A partial schematic diagram of the CC section shows that the reinforcing member 10 has at least one recessed area 103 that is recessed toward the root reinforcing cavity 40. The recessed areas 103 are arranged at intervals along the width direction Y of the vehicle. The recessed area 103 is provided with a weight reduction hole 101 that connects to the root reinforcing cavity 40.

[0084] The recessed area 103 is a sunken structure provided on the reinforcing member 10. For example, its sunken amount can be one-third of the cross-sectional height of the root reinforcing cavity 40. The recessed area 103 can be formed by stamping or die casting through the reinforcing member 10. There can be one, two, or more recessed areas 103. The specific number and spacing are adjusted according to the structural strength requirements. Figures 7 to 9 The illustration shows a case where two recessed areas 103 are provided on the reinforcing member 10.

[0085] By setting the recessed area 103, the collision path transmission in this area can be made to present a multi-gradient shape. This design can make the force transmission path smoother and reduce stress concentration.

[0086] The weight-reducing hole 101 is a through-hole structure provided on the reinforcing member 10. The shape of the weight-reducing hole 101 can be circular, elliptical, or rectangular. There can be one, two, or more weight-reducing holes 101. The specific number and spacing are adjusted according to the structural strength requirements. Figures 7 to 9 The illustration shows a case where two weight-reducing holes 101 are provided on the reinforcing member 10.

[0087] By setting the weight reduction hole 101, the overall weight of the reinforcing member 10 can be effectively reduced, so that the reinforcing member 10 can reduce the amount of material used and reduce manufacturing costs while meeting the collision safety requirements. In addition, under collision conditions, the weight reduction hole 101 can also buffer the large collision energy, thereby reducing the risk of stress concentration under large collision energy.

[0088] The dimensions and positions of the weight-reducing holes 101 can be designed in various ways in this application embodiment. For example, weight-reducing holes 101 of different diameters can be provided in different parts of the reinforcing member 10, or an asymmetrical arrangement can be adopted to adapt to specific stress requirements.

[0089] The weight reduction hole 101 in this embodiment can also be replaced with a solution of local thickness reduction, which can also achieve the weight reduction effect.

[0090] In some embodiments, see again Figure 2 The rear frame assembly 30 has a frame overlap edge 301, the luggage compartment panel 20 overlaps the frame overlap edge 301, and the two ends of the reinforcing member 10 in the length direction overlap the frame overlap edge 301 with the luggage compartment panel 20.

[0091] The luggage compartment panel 20 can be welded to the frame overlap edge 301. The periphery of the luggage compartment panel 20 can be welded to the frame overlap edge 301, and the two ends of the reinforcing member 10 in the length direction can be welded to the side of the luggage compartment panel 20 away from the frame overlap edge 301. This forms a three-layer overlap structure at the frame overlap edge 301, so that the collision force transmitted by the reinforcing member 10 can also be effectively transmitted to the rear frame assemblies 30 on both sides along the length direction of the reinforcing member 10, which is the width direction Y of the vehicle.

[0092] In this embodiment, the rear frame assembly 30, the luggage compartment panel 20, and the reinforcing member 10 form a three-layer overlapping structure. In other embodiments, the two ends of the reinforcing member 10 in the length direction can also be directly overlapped with the rear frame assembly 30. Specifically, the two ends of the reinforcing member 10 in the length direction can be folded and overlapped with the frame extension 303 described below.

[0093] In some embodiments, the frame overlap edge 301 includes a first frame overlap edge 3011 extending along the width direction Y of the vehicle and second frame overlap edges 3012 located on both sides of the first frame overlap edge 3011 in the width direction Y of the vehicle. The second frame overlap edges 3012 extend along the length direction X and / or height direction Z of the vehicle. The two second frame overlap edges 3012 are spaced apart from one end of the first frame overlap edge 3011. The first frame overlap edge 3011 and the two second frame overlap edges 3012 together form a frame overlap opening 302. The periphery of the trunk panel 20 overlaps with the frame overlap edge 301 and at least a portion of the trunk panel 20 is embedded in the frame overlap opening 302.

[0094] In this embodiment, the multi-directional extension structure of the frame overlap edge 301 increases the overlap area between the trunk panel 20 and the rear frame assembly 30, thereby improving the connection strength. Two spaced-apart second frame overlap edges 3012, together with the first frame overlap edge 3011, form an open overlap opening 302. The trunk panel 20 is partially embedded in the overlap opening 302, ensuring the installation and positioning of the trunk panel 20 while allowing the load transmitted by the trunk panel 20 to be distributed along the width direction Y and length direction X of the vehicle to the entire rear frame assembly 30. Through multiple force transmission paths, the energy dispersion effect during a rear-end collision is improved. This structural design, while maintaining the trunk volume, effectively improves the structural weakness of the trunk panel 20's root area by optimizing the stress transmission path, thus enhancing overall collision safety.

[0095] In some embodiments, the second frame overlap edge 3012 includes a first overlap edge portion 30121 and a second overlap edge portion 30122 arranged at an angle. The second overlap edge portion 30122 and the first frame overlap edge 3011 are spaced apart along the height direction Z of the vehicle. The first overlap edge portion 30121 extends along the height direction Z of the vehicle and connects the second overlap edge portion 30122 and the first frame overlap edge 3011. The periphery of the trunk panel 20 overlaps with the first frame overlap edge 3011, the first overlap edge portion 30121 and the second overlap edge portion 30122, so that the rear frame assembly 30 and the trunk panel 20 together form a stepped reinforcing cavity 50.

[0096] In this embodiment, the second frame overlapping edge 3012 is designed with an angled structure. The shape of the second frame overlapping edge 3012 is adapted to the shape of the edge of the trunk panel 20 in the width direction Y of the vehicle, so that the edge of the trunk panel 20 in the width direction Y of the vehicle can better fit the second frame overlapping edge 3012. It is precisely because the trunk panel 20 has an angled structure, and the shape of the second frame overlapping edge 3012 adapted to the trunk panel 20 is also an angled structure, that the rear frame assembly 30 and the trunk panel 20 together form a stepped reinforcing cavity 50. The stepped reinforcing cavity 50 can be understood as the trunk formed by the rear frame assembly 30 and the trunk panel 20 in the above embodiment. This stepped reinforcing cavity 50 has a large volume, optimizes space utilization, and also improves structural rigidity.

[0097] In order to improve the structural strength of the second frame overlap edge 3012, the rear frame assembly 30 has a frame extension 303. The frame extension 303 protrudes along the height direction Z of the vehicle relative to other parts of the rear frame assembly 30.
