The rear wheel housing inner plate reinforcement plate 12 is tightly fitted with the C-pillar outer plate 53 and the rear wheel housing inner plate 11, and the structure of the rear side enclosure assembly 10 is strengthened, effectively improving the NVH performance of the rear side enclosure assembly 10.

[0051] like Figure 1-Figure 3As shown, the shelf assembly 40 includes: a shelf front crossbeam 41, a shelf rear crossbeam 42 and two shelf connecting plates 43, and the shelf connecting plates 43 are arranged between the shelf front crossbeam 41 and the shelf rear crossbeam 42. Specifically, the shelf assembly 40 is connected to the rear side enclosure assembly 10 on both sides in the width direction, and the rear side enclosure assembly 10 provides support for the shelf assembly 40. The shelf front crossbeam 41 and the shelf rear crossbeam 42 both extend in the width direction of the vehicle. The two shelf connecting plates 43 are respectively arranged on both sides in the width direction of the vehicle. The two shelf connecting plates 43 are arranged at intervals in the width direction, and the two shelf connecting plates 43 are spaced and connected between the shelf front crossbeam 41 and the shelf rear crossbeam 42. The shelf assembly 40 is used to place some items to provide convenience for users.

[0052] Furthermore, since the shelf front cross beam 41 is connected to the shelf connecting plate 43, the shelf connecting plate 43 is connected to the C-pillar outer panel 53, the C-pillar outer panel 53 is connected to the side panel taillight mounting plate 54, and the side panel taillight mounting plate 54 is connected to the rear panel assembly 20, the shelf front cross beam 41, the shelf connecting plate 43, the rear wheel housing inner panel reinforcement plate 12, the two C-pillar outer panels 53, the two side panel taillight mounting plates 54 and the rear panel assembly 20 form a first annular structure 62, which further improves the torsional stiffness of the vehicle body, greatly improves the normal NVH performance, and effectively avoids the generation of abnormal noises between the shelf assembly 40, the side panel taillight mounting plates 54 and the rear panel assembly 20. The side taillight mounting plate 54 is tightly connected to the C-pillar outer panel 53 , which effectively enhances the structural strength and durability; the rear wheel housing inner panel reinforcement plate 12 fits tightly with the C-pillar outer panel 53 and the rear wheel housing inner panel 11 , and the structure of the rear side panel assembly 10 is strengthened, which effectively improves the NVH performance of the rear side panel assembly 10 .

The projection line of the second ring structure 61, the fourth ring structure and the third ring structure on the plane formed by the length and height directions of the vehicle is a trapezoid. This trapezoidal cage structure supports the third ring structure through the second ring structure 61 and the fourth ring structure, which can significantly improve the torsional stiffness of the vehicle body and the safety performance of the whole vehicle. The installation stiffness of each component between the ring structures is effectively improved, thereby improving the modal and NVH performance of the whole vehicle and improving driving comfort.

[0059] When the third annular structure is subjected to stress, the stress is transmitted to the fourth annular structure through the shelf board front cross beam 41, and part of the stress can be transmitted to the second annular structure 61 through the shelf board rear cross beam 42. When the fourth annular structure is subjected to stress, part of the stress is transmitted to the third annular structure through the shelf board front cross beam 41, and part of the stress can be transmitted to the second annular structure 61 through the shelf board rear cross beam 42, thereby improving the torsional stiffness of the shelf board assembly 40, the rear seats and the tailgate, and improving the local and vehicle modal performance.
