In addition, unless otherwise specified, "multiple" means two or more.

[0034] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figure 1-11 As shown, some embodiments of the present invention provide a modular upper vehicle body, comprising a side panel reinforcement inner frame assembly 2, a rear side panel inner panel assembly 1, a roof rear cross beam assembly 4 and a roof front cross beam assembly 3.

[0036] The side wall reinforcement inner frame assembly 2 includes an A-pillar upper reinforcement plate 21 , a B-pillar reinforcement plate 22 and a door sill outer reinforcement plate 23 which are connected in pairs.

[0037] The rear side enclosure inner panel assembly 1 is arranged at the rear side of the side enclosure reinforcement inner frame assembly 2, and the rear side enclosure inner panel assembly 1 includes a C-pillar lower reinforcement plate 11 and a rear wheel housing outer panel 12, and an enclosed space is formed between the C-pillar lower reinforcement plate 11 and the rear wheel housing outer panel 12.

[0038] The top cover rear cross beam assembly 4 is installed above the rear side wall inner panel assembly 1 .

[0039] The top cover front cross beam assembly 3 is arranged at the front side of the top cover rear cross beam assembly 4 and is installed above the side wall reinforcement inner frame assembly 2 .

[0040] Based on the above structural arrangement, the adopted side panel reinforcement inner frame assembly 2 includes an A-pillar upper reinforcement plate 21, a B-pillar reinforcement plate 22 and a door sill outer reinforcement plate 23 which are connected in pairs; the rear side panel inner panel assembly 1 is arranged on the rear side of the side panel reinforcement inner frame assembly 2, and the rear side panel inner panel assembly 1 includes a C-pillar lower reinforcement plate 11 and a rear wheel housing outer panel 12, and an enclosed space is formed between the C-pillar lower reinforcement plate 11 and the rear wheel housing outer panel 12, and the above-mentioned reinforcement plates can enhance the strength of the upper vehicle body structure, so that the upper vehicle body structure meets various design standard requirements, thereby reducing development costs.

[0041] To meet the five-star C-NCAP crash test standard, the modular upper body is also equipped with the following structures:

[0042] like Figure 1 As shown, in some embodiments, the A-pillar upper reinforcement plate 21 includes at least two pieces, and each A-pillar upper reinforcement plate 21 is fixedly connected. Specifically, the A-pillar upper reinforcement plates 21 are fixed by spot welding or double welding to improve the strength of the A-pillar and improve the offset collision deformation.

[0043] like Figure 1 and 4 As shown, in some embodiments, the side enclosure reinforcement inner frame assembly 2 includes a B-pillar structure 24 and a first rear door hinge lower reinforcement plate 25a, the B-pillar structure 24 and the first rear door hinge lower reinforcement plate 25a are installed on the B-pillar reinforcement plate 22, and the rear side enclosure inner panel assembly 1 includes a C-pillar structure 13, and the C-pillar structure 13 is installed in the enclosed space. Exemplarily, the B-pillar structure 24 and the C-pillar structure 13 are supported by PA6+epoxy resin material and installed by snap-fit. The first rear door hinge lower reinforcement plate 25a is connected by spot welding. In this way, the strength of the B-pillar and the C-pillar is strengthened, and when a collision occurs, the front and rear side doors can be effectively supported, thereby reducing the intrusion of the B-pillar and the C-pillar.

[0044] like Figure 8 and 9As shown, in some embodiments, the front cross beam assembly 3 of the roof includes a front cross beam 31 of the roof and a front cross beam reinforcement plate 32 of the roof, and the front cross beam reinforcement plate 32 of the roof is installed on the front cross beam 31 of the roof, and the rear cross beam assembly 4 of the roof includes a rear cross beam outer plate 43 of the roof, a rear cross beam inner plate 42 of the roof provided inside the rear cross beam outer plate 43 of the roof, and two tailgate hinge reinforcement plates 41 provided at both ends of the rear cross beam outer plate 43 of the roof. Specifically, the front cross beam assembly 3 of the roof and the rear cross beam assembly 4 of the roof are both double-layer plate structures, which can better improve the connection strength and rigidity of the vehicle body frame, ensure that the deformation of the vehicle body is reduced when the vehicle body is subjected to top pressure, side collision or rollover, and provide sufficient living space for the occupants.

[0045] like Figure 6 As shown, in some embodiments, the side reinforcement inner frame assembly 2 includes an aluminum alloy anti-collision rod 26a and a plurality of first threshold outer reinforcement plate brackets 27a. The aluminum alloy anti-collision rod 26a is installed on the threshold outer reinforcement plate 23 through the first threshold outer reinforcement plate bracket 27a, and the cross-section of the aluminum alloy anti-collision rod 26a is a grid shape. Among them, the aluminum alloy anti-collision rod 26a is made of 6082-T6 material. While maintaining a certain hardness, the aluminum alloy material also has a certain toughness, and can absorb energy through deformation during a collision, reducing the intrusion of the battery pack, the chest and abdomen height of the front door dummy, and the chest and abdomen height of the rear door dummy. The aluminum alloy anti-collision rod 26a and the first threshold outer reinforcement plate bracket 27a are connected by riveting, and the first threshold outer reinforcement plate bracket 27a and the threshold outer reinforcement plate 23 are connected by spot welding.

[0046] To meet the Latin-NCAP one-star crash test standard, the modular upper body is also equipped with the following structures:

[0047] like Figure 2 As shown, in some embodiments, the side enclosure reinforcement inner frame assembly 2 includes a B-pillar structure 24 and a second rear door hinge lower reinforcement plate 25b, the B-pillar structure 24 and the second rear door hinge lower reinforcement plate 25b are installed on the B-pillar reinforcement plate 22, and the rear side enclosure inner panel assembly 1 includes a C-pillar structure 13, and the C-pillar structure 13 is installed in the enclosed space. Among them, the second rear door hinge lower reinforcement plate 25b is shortened by 125mm in the Z direction compared with the first rear door hinge lower reinforcement plate 25a.

[0048] like Figure 7As shown, in some embodiments, the side enclosure reinforcement inner frame assembly 2 includes a steel anti-collision bar 26b, a second sill outer reinforcement plate bracket 27b, and a plurality of first sill outer reinforcement plate brackets 27a. The steel anti-collision bar 26b is installed on the sill outer reinforcement plate 23 through the first sill outer reinforcement plate brackets 27a and the second sill outer reinforcement plate bracket 27b. The cross-section of the steel anti-collision bar 26b is in the shape of a Chinese character 'Mu'. Specifically, the steel anti-collision bar 26b is made by a rolling process and the material is HC950 / 1180MS-FB-D. The steel anti-collision bar 26b has higher strength, which can reduce the intrusion amounts of the battery pack, the chest and abdomen heights of the front door dummy, and the chest and abdomen heights of the rear door dummy; the volume of the second sill outer reinforcement plate bracket 27b is increased compared with that of the first sill outer reinforcement plate bracket 27a.

[0049] To meet the national collision test standards, the modular upper body is also configured with the following structures:

[0050] As Figure 3 shown, in some embodiments, the side enclosure reinforcement inner frame assembly 2 includes a second rear door hinge lower reinforcement plate 25b and a plurality of second sill outer reinforcement plate brackets 27b. The second rear door hinge lower reinforcement plate 27b is installed on the B-pillar reinforcement plate 22, and the second sill outer reinforcement plate brackets 27b are installed on the sill outer reinforcement plate 23.

[0051] As Fig.10 and 11 shown, in some embodiments, the front roof cross member assembly 3 includes a front roof cross member 31, and the rear roof cross member assembly 4 includes a rear roof cross member outer plate 43 and two tailgate hinge reinforcement plates 41 respectively arranged at both ends of the rear roof cross member outer plate 43.

[0052] The national standard body does not need to carry modular parts, which can reduce the weight by 9.04 kg, improve the vehicle's endurance, and enhance the competitiveness.

[0053] In summary, based on the national collision test standard scheme, the Latin-NCAP one-star collision test standard realizes the switching of bodies with different safety requirements by adding or replacing parts in the cavity with no other changes, which can save the tooling and die costs caused by the change of material thickness; compared with the national collision test standard scheme, this scheme reduces the B-pillar intrusion amount by about 50 mm, the battery pack intrusion amount by about 4.7 mm, the chest and abdomen height intrusion amount of the front door dummy by about 37 mm, and the chest and abdomen height intrusion amount of the rear door dummy by about 25 mm.

[0054] Based on the Latin-NCAP one-star crash test standard, the C-NCAP five-star crash test standard achieves body switching with different safety requirements by adding or replacing parts in the cavity while keeping the rest unchanged, which is an efficient design. Compared with the national crash test standard, this scheme reduces the intrusion of the B-pillar by about 40mm, the intrusion of the battery pack by about 6.5mm, the intrusion at the chest and abdomen height of the front door dummy by about 24mm, and the intrusion at the chest and abdomen height of the rear door dummy by about 22.5mm.

[0055] In addition, since only parts are added or replaced in the cavity, the boundaries and material thickness of large body parts are not changed, there is no need to make drastic changes to the body production line, interior and exterior parts, which greatly reduces development costs and can save development cycles.

[0056] Vehicles provided in other embodiments of the present invention include the building block upper body of some embodiments.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
