In the trunk assembly, the side of the rear floor assembly extending in a first direction provides an installation reference for the front section of the longitudinal beam. The rear floor assembly, a first rear section, a second rear section, and the trunk panel together form the trunk assembly. By extending the first rear section outwards relative to the first front section away from the trunk panel, and by extending the second rear section outwards relative to the second front section away from the trunk panel, the lateral space occupied by the trunk can be reduced, allowing the trunk panel to gain additional extended space on both sides of the vehicle's lateral direction, thereby increasing the trunk's volume ratio and improving its load-bearing capacity.

Description

Technical Field

[0001] This application relates to the field of vehicle equipment technology, and more particularly to a trunk assembly and a vehicle. Background Technology

[0002] The trunk assembly of a vehicle typically provides storage space, which is commonly used to store items. The volume of the trunk assembly directly affects the load-bearing capacity of the vehicle's trunk. In related technologies, the storage space of the trunk assembly is enclosed by the trunk panel, two rear longitudinal beams, and the rear floor.

[0003] However, the trunk assembly in the aforementioned related technologies has a small volume, which affects the load-bearing capacity of the trunk assembly. Utility Model Content

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0050] The trunk assembly in the aforementioned technologies has a relatively small volume, affecting its load-bearing capacity. This problem arises because, due to limitations in the layout of the powertrain and suspension structure, the trunk storage space in new energy vehicles often suffers from insufficient dimensions in the width direction of the vehicle body.

[0051] To address the aforementioned issues, this application provides a trunk assembly and a vehicle. The side of the rear floor assembly extending along a first direction provides an installation reference for the front section of the longitudinal beam. The rear floor assembly, the first rear section, the second rear section, and the trunk panel together form the trunk assembly. By extending the first rear section outward relative to the first front section away from the trunk panel, and by extending the second rear section outward relative to the second front section away from the trunk panel, the lateral space occupied by the trunk can be reduced, allowing the trunk panel to gain additional extended space on both sides of the vehicle's lateral direction. This increases the trunk volume ratio of the trunk assembly and improves the load-bearing capacity of the trunk assembly.

[0052] The trunk assembly and vehicle provided in this application are described below with reference to the accompanying drawings and specific embodiments.

[0053] Reference Figure 1 and Figure 2 This application provides a trunk assembly, which may include a rear floor assembly 100, a trunk panel 200, and a first rear longitudinal beam 300 and a second rear longitudinal beam 400 symmetrically arranged laterally on both sides of the trunk panel 200 and the rear floor assembly 100 of the vehicle. The first rear longitudinal beam 300 and the second rear longitudinal beam 400 can have identical structures, and the first rear longitudinal beam 300 and the second rear longitudinal beam 400 are symmetrically arranged about the central axis of the vehicle's length direction.

[0054] The rear floor assembly 100 may include components along a first direction (e.g., Figure 1 The first side 110 and the second side 120 (in the X direction). The rear floor assembly 100 refers to the basic structure that bears the load of the rear of the vehicle. Specifically, it can be realized by combining stamped aluminum alloy sheet and extruded profile to form a support platform with predetermined rigidity.

[0055] Along the second direction (e.g.) Figure 1In the Y direction, the trunk panel 200 is connected to the rear floor assembly 100. The trunk panel 200 may include a third side 210 and a fourth side 220 opposite to each other along the first direction. The third side 210 is on the same side as the first side 110, and the second direction is perpendicular to the first direction. The trunk panel 200 refers to the component that forms the bottom of the storage space. Specifically, it can be formed by a stamping process and maintains a height difference with the rear floor 130 to form a recessed storage area.

[0056] The first rear longitudinal beam 300 may include a first front section 310 and a first rear section 320 connected to each other along a second direction. The first front section 310 is disposed on a first side 110 of the rear floor assembly 100, and the first rear section 320 is disposed on a third side 210 of the trunk panel 200. The second rear longitudinal beam 400 may include a second front section 410 and a second rear section 420 connected to each other along a second direction. The second front section 410 is disposed on a second side 120 of the rear floor assembly 100, and the second rear section 420 is disposed on a fourth side 220 of the trunk panel 200.

[0057] The first front section 310 and the second front section 410 are arranged symmetrically, and the first rear section 320 and the second rear section 420 are also arranged symmetrically. The first rear section 320, the second rear section 420, the trunk panel 200 and the rear floor assembly 100 together form the trunk assembly.

[0058] Along the first direction, the first rear section 320 extends outward relative to the first front section 310 away from the rear trunk panel 200, and the second rear section 420 extends outward relative to the second front section 410 away from the rear trunk panel 200.

[0059] This application provides a trunk assembly where the side of the rear floor assembly 100 extending in a first direction provides an installation reference for the front section of the longitudinal beam. The rear floor assembly 100, the first rear section 320, the second rear section 420, and the trunk panel 200 together form the trunk assembly. By making the first rear section 320 extend outward relative to the first front section 310 away from the trunk panel 200, and by making the second rear section 420 extend outward relative to the second front section 410 away from the trunk panel 200, the lateral space occupied by the trunk can be reduced, and the trunk panel 200 can obtain additional extended space on both sides of the vehicle's lateral direction, thereby increasing the trunk volume ratio of the trunk assembly and improving the load-bearing capacity of the trunk assembly.

[0060] Reference Figure 1 and Figure 2 In some embodiments, the first rear segment 320 may include a first transition segment 321 and a first straight segment 322. One end of the first transition segment 321 is connected to the first front segment 310, and the other end is connected to the first straight segment 322. Both the first straight segment 322 and the first front segment 310 extend along a second direction, and the first transition segment 321 is inclined relative to the first straight segment 322.

[0061] The first transition section 321 refers to the inclined structure connecting the first front section 310 and the first straight section 322. Specifically, it can be implemented using an arc-shaped or zigzag transition structure to change the direction of force transmission and disperse the impact load. The first straight section 322 refers to the straight structure that extends in the same direction as the first front section 310, and is used to receive the longitudinal impact force from the rear of the vehicle.

[0062] Specifically, the first transition section 321 connects the first front section 310 and the first straight section 322 at an inclined angle, forming a smooth force transmission transition area. When the rear of the vehicle is impacted, the impact force is transmitted to the first transition section 321 through the first straight section 322. The inclined structure converts part of the impact force into a lateral component, while the remaining longitudinal component continues to be transmitted through the first front section 310. The first straight section 322 and the first front section 310 maintain the same extension direction to ensure the continuity of the longitudinal force transmission path and avoid stress concentration.

[0063] This solution optimizes the distribution of the force transmission path by setting an inclined first transition section 321 and a first straight section 322, which not only disperses the impact load but also maintains the stability of longitudinal force transmission.

[0064] Through the above technical solution, this application can effectively disperse and transfer load when the rear of the vehicle is impacted, avoid component failure caused by local stress concentration, and at the same time ensure the continuity of the longitudinal force transmission path, thereby improving the overall energy absorption efficiency and structural reliability of the first rear longitudinal beam 300.

[0065] Reference Figure 1 and Figure 2 In some embodiments, along the first direction, the dimension by which the first rear section 320 extends outward relative to the first front section 310 away from the rear trunk panel 200 is a first distance, the first distance (e.g. Figure 2 The first distance (as shown by h) is greater than or equal to 60 mm and less than or equal to 65 mm. For example, the first distance can be one of 60 mm, 61 mm, 62 mm, 63 mm, 64 mm and 65 mm, or the first distance can be any point value within the range of greater than or equal to 60 mm and less than or equal to 65 mm.

[0066] The first distance refers to the outward extension of the first rear section 320 relative to the first front section 310 in the first direction. Specifically, it can be achieved by controlling the extension length of the rear section of the longitudinal beam. This distance range can ensure the expansion of the trunk assembly width while maintaining the mechanical transmission efficiency of the main structure of the longitudinal beam.

[0067] Specifically, the setting of the first distance ensures that while the width of the first rear section 320 is expanded, its outward extension is controlled within a range that does not weaken the main structural rigidity of the first rear longitudinal beam 300, thus ensuring the load-bearing capacity of the connection area between the first rear section 320 and the trunk panel 200.

[0068] Through the above technical solution, this application optimizes the energy absorption path of the rear longitudinal beam when impacted at the rear of the vehicle, ensuring that the first rear section 320 maintains sufficient longitudinal load transfer capacity while expanding the width of the trunk assembly, thus avoiding a decrease in energy absorption effect due to structural deformation. This design achieves a balance between expanding the trunk assembly volume and vehicle safety performance within a limited space.

[0069] Reference Figure 1 and Figure 2 In some embodiments, the second rear segment 420 may include a second transition segment and a second straight segment, with one end of the second transition segment connected to the second front segment 410 and the other end connected to the second straight segment. Both the second straight segment and the second front segment 410 extend along a second direction, and the second transition segment is inclined relative to the second straight segment.

[0070] The second transition section refers to the inclined portion of the second rear section 420 connecting the second front section 410 and the second straight section. This can be achieved using a bent structure formed by stamping or extrusion processes, and its inclination angle can be adjusted according to actual force transmission requirements. The second straight section refers to the straight portion of the second rear section 420 extending along the second direction. This can be achieved using an integrally formed structure made of the same material as the second front section 410 to maintain the continuity of the force transmission path.

[0071] Specifically, the second rear longitudinal beam 400 achieves a smooth transition between the second front section 410 and the second straight section through a second transition section. The inclined design of the second transition section causes the second rear section 420 to extend outward in the first direction, while the second straight section extends along the second direction, ensuring the continuity of the longitudinal force transmission path. The second transition section adjusts the outward extension range by adjusting the inclination angle to avoid force transmission path deviation due to excessive outward extension distance, thereby optimizing the force distribution of the second rear longitudinal beam 400.

[0072] This solution divides the second rear longitudinal beam 400 into a second front section 410, a second transition section, and a second straight section through a segmented design. This achieves both outward extension to increase the width of the trunk assembly and maintains the stability of the longitudinal force transmission path through the second straight section, thus solving the problem of force transmission path breakage caused by excessive outward extension in traditional structures.

[0073] Through the above technical solution, this application can ensure that when the rear of the vehicle is impacted, the impact force of the second rear longitudinal beam 400 is transmitted sequentially along the second straight section, the second transition section and the second front section 410, avoiding stress concentration. At the same time, the outward design provides a larger width space for the trunk assembly, improving vehicle safety and space utilization.

[0074] Reference Figure 1 and Figure 2 In some embodiments, along the first direction, the dimension by which the second rear section 420 extends outward relative to the second front section 410 away from the rear trunk panel 200 is a second distance, which is greater than or equal to 60 mm and less than or equal to 65 mm. For example, the first distance can be one of 60 mm, 61 mm, 62 mm, 63 mm, 64 mm, and 65 mm, or the first distance can be any point value within the range of greater than or equal to 60 mm and less than or equal to 65 mm.

[0075] The second distance refers to the outward extension of the second rear section 420 relative to the second front section 410 in the first direction. Specifically, it can be achieved by controlling the extension length of the second rear section 420. This distance range can ensure both the expansion of the trunk assembly width and the maintenance of the mechanical transmission efficiency of the main longitudinal beam structure.

[0076] Specifically, the setting of the second distance ensures that while the width of the second rear section 420 is expanded, its outward extension is controlled within a range that does not weaken the main structural rigidity of the second rear longitudinal beam 400, thus ensuring the load-bearing capacity of the connection area between the second rear section 420 and the trunk panel 200.

[0077] Through the above technical solution, this application optimizes the energy absorption path of the second rear longitudinal beam 400 when impacted at the rear of the vehicle, enabling the second rear section 420 to maintain sufficient longitudinal load transfer capacity while expanding the width of the trunk assembly, thus avoiding a decrease in energy absorption effect due to structural deformation. This design achieves a balance between expanding the trunk assembly volume and vehicle safety performance within a limited space.

[0078] Reference Figure 1 , Figure 3 and Figure 5 In some embodiments, the rear floor assembly 100 may include a rear floor 130 and a rear crossbeam 140 interconnected. Along a second direction, the rear crossbeam 140 is located between the rear floor 130 and the trunk panel 200, with the rear floor 130 connected to the trunk panel 200 via the rear crossbeam 140. Along a third direction (e.g.... Figure 5 In the Z direction, the trunk panel 200 is close to the bottom of the vehicle relative to the rear floor 130, so that the trunk panel 200, the first rear section 320, the second rear section 420 and the rear crossbeam 140 form a trunk slot 230.

[0079] The rear crossbeam 140 refers to the connecting component arranged laterally between the rear floor 130 and the rear trunk panel 200. It can be made of a one-piece extruded aluminum alloy profile and is used to transfer longitudinal loads and form structural support. The third direction refers to the vertical direction perpendicular to the first and second directions, used to describe the height difference between the rear trunk panel 200 and the rear floor 130. The rear trunk slot 230 refers to the recessed space enclosed by the rear crossbeam 140, the rear trunk panel 200, the first rear section 320, and the second rear section 420. This can be achieved by adjusting the relative height between the rear crossbeam 140 and the rear trunk panel 200, and can at least accommodate folding seats and expand storage space.

[0080] Specifically, the rear floor 130 and the rear crossbeam 140 are fixed by a mechanical connection. The rear crossbeam 140 extends along the longitudinal direction of the vehicle and is located between the trunk panel 200 and the rear floor 130. The trunk panel 200 is lower than the plane of the rear floor 130 in the vertical direction, forming a downwardly recessed groove structure together with the rear sections of the two rear longitudinal beams and the rear crossbeam 140. This groove extends in the width direction of the vehicle, and its depth is determined by the cross-sectional height of the rear crossbeam 140.

[0081] Through the above technical solution, this application realizes the three-dimensional space construction of the trunk slot 230, which effectively increases the storage volume by vertically stacking the space while maintaining the structural strength of the rear floor assembly 100.

[0082] Reference Figure 1 and Figure 5 In some embodiments, the rear crossbeam 140 is a one-piece structure. This one-piece structure means that the rear crossbeam 140 is integrally formed through a single process, specifically using an extruded aluminum alloy profile process. This process involves continuous extrusion to form an integral structure with a predetermined cross-section. The extrusion forming process avoids the breakage risk associated with traditional sheet metal bending, while ensuring the structural continuity and strength consistency of the rear crossbeam 140 along its length.

[0083] Specifically, the rear crossbeam 140 is formed into a single structure through an extrusion process, eliminating the need for multi-segment sheet metal splicing or bending. This structure directly forms the required cross-sectional shape and size during manufacturing, avoiding the breakage problems caused by the limited ductility of materials in traditional sheet metal bending processes. Due to the integrity of the single-piece structure, the rear crossbeam 140 is directly connected to the rear floor 130 and the rear trunk panel 200 during installation, without the need for additional reinforcement or welding, thereby reducing the space occupied in the second direction.

[0084] Compared to existing technologies, traditional rear crossbeams 140 typically employ multiple sheet metal segments bent and spliced ​​to form a U-shaped cross-section. This bending process is limited by material ductility, requiring a large bending radius to prevent breakage and increasing space occupancy in the secondary direction. In contrast, the integrated rear crossbeam 140 of this application directly obtains the target cross-section through extrusion molding, eliminating the need for bending. This avoids the risk of breakage, reduces space occupancy in the secondary direction, and simultaneously improves bending stiffness and torsional performance.

[0085] Through the above technical solution, this application solves the problem of second-direction space encroachment caused by the bending process limitations of the traditional sheet metal rear crossbeam 140. While ensuring the depth of the trunk compartment 230, the second-direction dimensions of the rear crossbeam 140 are made more compact, thereby providing space for the trunk compartment 230 to expand along the second direction and further increasing the trunk volume. Furthermore, the one-piece structure of the rear crossbeam 140 has higher structural strength and stability, enabling better load transfer and improving overall vehicle performance.

[0086] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, the trunk assembly may further include a rear folding seat 500. The rear folding seat 500 is disposed on the rear floor 130 and rotatably connected to the rear crossbeam 140. The rear folding seat 500 is folded and flipped relative to the rear crossbeam 140 into the trunk compartment 230.

[0087] In some embodiments, the rear folding seat 500 may include a backrest 510 and a seat cushion 520, the seat cushion 520 and the backrest 510 being able to rotate relative to each other and fold down, the backrest 510 being rotatably connected to the rear crossbeam 140 so that the seat cushion 520 and the backrest 510, after being folded down, flip relative to the rear crossbeam 140 and fall into the trunk slot 230.

[0088] The rear folding seat 500 refers to a rear seat in a vehicle that can be folded and stored via a hinge mechanism. Specifically, it can be implemented using a flip-up structure with a rotating axis, with a folding hinge between the seat cushion 520 and the backrest to achieve the folding action. The rotatable connection between the rear folding seat 500 and the rear crossbeam 140 means that the rear folding seat 500 and the rear crossbeam 140 are assembled via a rotating joint. Specifically, it can be implemented using a pivot structure with bearings, allowing the rear folding seat 500 to rotate around an axis.

[0089] Specifically, the rotation axis of the rear folding seat 500 is parallel to the length direction of the rear crossbeam 140. When the rear folding seat 500 is in the unfolded state, it can be used for passenger seating. During the folding process, the rear folding seat 500 rotates around the rear crossbeam 140, causing the folded seat to sink into the trunk compartment 230.

[0090] This solution optimizes the structure of the rear crossbeam 140 to form a sunken trunk slot 230, allowing the rear folding seats 500 to be fully embedded inside the slot, thus avoiding the space encroachment problem caused by the rear folding seats 500 after folding.

[0091] Through the above technical solution, the outward design of the first rear section 320 and the second rear section 420 enables the trunk slot 230 to accommodate the rear folding seat 500 in the first direction, realizing the complete integration of the folding seat and the trunk space. The folded rear folding seat 500 is stored inside the trunk slot 230, avoiding the problem of the seat occupying vertical space after folding in the traditional structure, which facilitates the loading and fixing of large items.

[0092] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, when the rear folding seat 500 is in the folded state and located within the trunk slot 230, the surface of the rear folding seat 500 facing away from the trunk panel 200 is flush with the rear floor 130. Here, "flush" means that the surface of the folding seat and the rear floor 130 are on the same plane, which can be achieved by matching the seat folding angle with the depth of the trunk slot 230 to eliminate height differences and ensure surface continuity.

[0093] Specifically, when the rear folding seat 500 is folded down and stored inside the trunk compartment 230 via the flipping mechanism, the surface of the seat back 510 facing the trunk panel 200 is structurally designed to remain flush with the upper surface of the rear floor 130. This design ensures that the folding seat does not bulge or sag by controlling the height relationship between the final position of the folded seat and the rear floor 130, thus creating a continuous loading surface.

[0094] This solution eliminates the surface height difference after storage by limiting the flush relationship between the folding seat and the rear floor 130, thus avoiding the problem of reduced space utilization caused by seat folding angle deviation or mismatch of groove depth in traditional solutions.

[0095] Through the above technical solution, this application enables the folded seat to form a seamless plane with the rear floor 130, improving the flatness of the trunk loading area, facilitating the placement and fixing of large items, and avoiding the waste of storage space caused by uneven surfaces.

[0096] This application also provides a vehicle that may include the aforementioned trunk assembly.

[0097] This application embodiment provides a vehicle in which the load-bearing capacity of the vehicle is improved by using the above-described trunk assembly.
