[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0036] Embodiment 1
[0037] This embodiment relates to a side wall rear reinforcement structure, which can improve the structural stability of the rear side wall of the vehicle; an exemplary structure thereof is as follows Figure 1 , Figure 2 and Figure 3 shown.
[0038] In general, the side rear reinforcement structure includes an inner connecting plate 2 arranged at the intersection of the upper side beam 1, the rear cross beam 3 of the roof, the C-pillar and the D-pillar. The inner connecting plate 2 has a C-pillar side connecting plate 20 extending along the C-pillar and a D-pillar side connecting plate 21 extending along the D-pillar. The tops of the C-pillar side connecting plate 20 and the D-pillar side connecting plate 21 are connected together to form an intersection 23, and the intersection 23 has an upper side beam connecting plate 231 protruding toward the upper side beam 1 and a rear cross beam connecting plate 232 protruding toward the rear cross beam 3 of the roof; the upper side beam 1 is overlapped on the upper side beam connecting plate 231, the rear cross beam 3 of the roof is overlapped on the rear cross beam connecting plate 232, and the C-pillar and the D-pillar are overlapped on the C-pillar side connecting plate 20 and the D-pillar side connecting plate 21, respectively.
[0039] Of course, the specific structural form of the inner connecting plate 2 can be in various forms; the design principle is: by setting multiple branches on the inner connecting plate 2, a stable foundation is provided for the overlap and fixation of the C-pillar, D-pillar, upper side beam 1 and the rear cross beam 3 of the roof. Specifically, in this embodiment, if Figure 3 and Figure 4 As shown, the inner connecting plate 2 also includes a CD column connecting inner plate 22 connected between the bottoms of the C column side connecting plate 20 and the D column side connecting plate 21. The C column side connecting plate 20, the D column side connecting plate 21 and the CD column connecting inner plate 22 form a triangular frame structure. The triangular frame structure can ensure the structural stability of the inner connecting plate 2, thereby improving the structural strength between the C column and the D column.
[0040] In addition, if Figure 2As shown, the C-pillar of this embodiment includes a C-pillar reinforcement plate 4 overlapped at the corner of the C-pillar side connecting plate 20 and the CD-pillar connecting inner plate 22, and the D-pillar includes a D-pillar reinforcement plate 5 overlapped on the D-pillar side connecting plate 21. In addition to connecting the main parts of the C-pillar and the D-pillar to the inner connecting plate 2, by overlapping the C-pillar reinforcement plate 4 of the C-pillar on the corner of the inner connecting plate 2 and overlapping the D-pillar reinforcement plate 5 of the D-pillar on the D-pillar side connecting plate 21 of the inner connecting plate 2, the C-pillar reinforcement plate 4 and the D-pillar reinforcement plate 5 can constitute a part of the triangular frame structure of the inner connecting plate 2, thereby greatly improving the connection stability between the C-pillar reinforcement plate 4 and the D-pillar reinforcement plate 5.
[0041] Based on the position setting of the above-mentioned C-pillar reinforcement plate 4 and D-pillar reinforcement plate 5, preferably, the side enclosure rear reinforcement structure of this embodiment also includes a CD-pillar connecting plate 6 overlapped on the CD-pillar connecting inner plate 22. Among them, the front end of the CD-pillar connecting plate 6 is connected to the C-pillar reinforcement plate 4, and the rear end of the CD-pillar connecting plate 6 is connected to the D-pillar reinforcement plate 5; at the same time, the bottom side of the CD-pillar connecting plate 6 is connected to the rear wheel cover assembly 7. The CD-pillar connecting plate 6 is set on the CD-pillar connecting inner plate 22 of the inner connecting plate 2, and the CD-pillar connecting plate 6 is connected with the C-pillar reinforcement plate 4 and the D-pillar reinforcement plate 5, so that the upper side beam 1, the inner connecting plate 2, the C-pillar reinforcement plate 4, the D-pillar reinforcement plate 5 and the CD-pillar connecting plate 6 form a triangular ring structure, which can effectively improve the structural rigidity and safety collision performance of the rear part of the side enclosure.
[0042] The angles between the upper side beam connecting plate 231 and the rear cross beam connecting plate 232 of the inner connecting plate 2, the upper side beam connecting plate 231 and the C-pillar side connecting plate 20, and the upper side beam connecting plate 231 and the D-pillar side connecting plate 21 can be reasonably set according to the corresponding upper side beam 1, the rear cross beam 3 of the roof, the C-pillar and the D-pillar. Preferably, the following scheme is adopted.
[0043] The angle between the upper side beam connecting plate 231 and the rear cross beam connecting plate 232 is between 95°-100°, for example, 95°, 98°, 100°, etc. The angle between the upper side beam connecting plate 231 and the C-pillar side connecting plate 20 is between 85°-90°, for example, 85°, 88°, 90°, etc. The angle between the upper side beam connecting plate 231 and the D-pillar side connecting plate 21 is between 130°-140°, for example, 130°, 135°, 140°, etc.
[0044] In addition, preferably, the protruding size of the upper side beam connecting plate 231 can be set between 65mm-70mm, such as 68mm; the protruding size of the rear cross beam connecting plate 232 can be set between 85mm-90mm, such as 86mm. By setting a reasonable protruding size, it can be ensured that there is sufficient overlapping contact area between the upper side beam 1, the rear cross beam 3 of the roof and the inner connecting plate 2, thereby ensuring the connection firmness between the upper side beam 1 and the inner connecting plate 2, and between the rear cross beam 3 of the roof and the inner connecting plate 2.
[0045] There are of course many options for the specific structural form of the roof side beam 1. In this embodiment, the roof side beam 1 includes a stacked roof side beam inner plate 10 and a roof side beam reinforcement plate 11; the roof side beam reinforcement plate 11 is arranged outside the roof side beam inner plate 10, as part of the side wall rear reinforcement structure, which can further enhance the structural strength of the vehicle side wall rear.
[0046] Specifically, if Figure 5 Combined with Figure 1 , Figure 2 As shown, the upper side beam 1 includes an upper side beam inner plate 10 and an upper side beam reinforcement plate 11 arranged on the outer side of the upper side beam inner plate 10; the rear end of the upper side beam inner plate 10 is overlapped on the upper side beam connecting plate 231, and the upper side beam reinforcement plate 11 includes a main body 110 located on the upper side beam inner plate 10 and a rear part overlapped on the intersection 23. The upper side beam 1 is designed to be a stacked upper side beam inner plate 10 and an upper side beam reinforcement plate 11. While the upper side beam inner plate 10 is overlapped on the upper side beam connecting plate 231, the upper side beam reinforcement plate 11 is overlapped and arranged on the outer side of the intersection 23 of the upper side beam inner plate 10 and the inner connecting plate 2; the connection reliability of the intersection 23 with the surrounding upper side beam 1, the rear cross beam 3 of the roof and other components can be further enhanced.
[0047] Based on the shape of the upper side beam reinforcement plate 11, the rear portion of the upper side beam reinforcement plate 11 of the present embodiment has a C-pillar overlapping section 111 protruding toward the C-pillar, a D-pillar overlapping section 112 protruding toward the D-pillar, and a rear cross beam overlapping section 113 protruding toward the rear cross beam 3 of the roof; the C-pillar overlapping section 111 is overlapped on the C-pillar side connecting plate 20, the D-pillar overlapping section 112 is overlapped on the D-pillar side connecting plate 21, and the rear cross beam overlapping section 113 is overlapped on the rear cross beam connecting plate 232. A raised C-pillar overlapping section 111, a D-pillar overlapping section 112 and a rear cross-beam overlapping section 113 are arranged at the rear end of the upper side beam reinforcement plate 11, that is, the rear end of the upper side beam reinforcement plate 11 adopts an integrated three-channel branching structure, which can more effectively transmit and transition the collision force from the upper side beam 1 smoothly in three directions; thereby improving the force transmission effect between the upper side beam 1 and the rear cross-beam 3 of the roof, the C-pillar and the D-pillar, and is conducive to improving the torsional rigidity of the rear structure of the side enclosure.
[0048] Meanwhile, as mentioned above, the C-pillar of this embodiment includes a C-pillar reinforcement plate 4 lapped at the corner of the C-pillar side connection plate 20 and the CD-pillar connection inner plate 22; meanwhile, the C-pillar of this embodiment further includes a C-pillar repair plate 40 lapped in the middle of the C-pillar side connection plate 20; and, the top end of the C-pillar repair plate 40 is connected to the C-pillar lapping section 111, and the bottom end of the C-pillar repair plate 40 is connected to the C-pillar reinforcement plate 4. The C-pillar repair plate 40 is added in the middle of the C-pillar side connection plate 20, and the C-pillar repair plate 40 cooperates with the C-pillar reinforcement plate 4, the C-pillar side connection plate 20, and the C-pillar lapping section 111 to jointly form a force transmission channel of the C-pillar, which can greatly improve the overall structural strength of the C-pillar.
[0049] Through the above settings, the upper side beam reinforcement plate 11, the C-pillar reinforcement plate 4, the D-pillar reinforcement plate 5, the CD-pillar connection plate 6, the C-pillar repair plate 40, etc. are all lapped on the inner connection plate 2 to jointly form a triangular closed-loop structure. At the same time, a "pin" shaped strong constraint framework is formed between the inner connection plate 2, the C-pillar, the D-pillar and the rear wheelhouse assembly 7. The rear wheelhouse assembly 7 of this embodiment includes a rear wheelhouse inner plate 71 and a rear wheelhouse outer plate 70 that are buckled together inside and outside; wherein, the bottoms of the C-pillar reinforcement plate 4, the D-pillar reinforcement plate 5 and the CD-pillar connection plate 6 are lapped on the rear wheelhouse outer plate 70, and a design conforming to the rear wheelhouse outer plate 70 is adopted, which can strengthen the connection tightness between various components, effectively improve the overall stiffness of the rear wheelhouse assembly 7, and avoid abnormal noises.
[0050] In summary, for the rear side panel reinforcement structure of this embodiment, by setting the inner connection plate 2 at the intersection of the upper side beam 1, the rear roof cross member 3, the C-pillar and the D-pillar, and the inner connection plate 2 adopts a multi-channel branched extension structure, so that the surrounding beam and column components are all lapped on the inner connection plate 2, enabling the upper side beam 1, the rear roof cross member 3, the C-pillar and the D-pillar to be reliably lapped and fixed on the inner connection plate 2, which not only increases the connection reliability between components, but also helps to improve the overall structural stability of the rear part of the vehicle side panel.
[0051] Embodiment Two
[0052] This embodiment relates to a vehicle, and the vehicle is provided with the rear side panel reinforcement structure provided in Embodiment One.
[0053] By setting the inner connection plate 2 at the intersection of the upper side beam 1, the rear roof cross member 3, the C-pillar and the D-pillar, and at the same time, the upper side beam reinforcement plate 11 of the upper side beam 1 adopts an integrated three-way structure, the collision force from the upper side beam 1 can be more effectively and smoothly transmitted and transitioned in three directions towards the rear roof cross member 3, the C-pillar and the D-pillar; the mutual support of the rear roof cross member 3, the C-pillar reinforcement plate 4 and the D-pillar reinforcement plate 5 effectively improves the structural torsional stiffness of the rear part of the side panel.
[0054] In addition, the upper side beam reinforcement plate 11, the C-pillar reinforcement plate 4, the D-pillar reinforcement plate 5 and the CD-pillar connecting plate 6 form a triangular closed-loop structure on the inner connecting plate 2, which effectively improves the structural rigidity and safety collision performance of the rear part of the side panel; the intersection 23 of the inner connecting plate 2 and the upper side beam reinforcement plate 11 of the upper side beam 1 both adopt a three-channel branch structure design, and the force transmission channel formed between the upper side beam 1, the rear cross beam 3 of the roof, the C-pillar and the D-pillar is more stable and reliable, which ensures the smoothness of force transmission at the rear part of the side panel and has a significant effect on improving the safety collision performance of the vehicle.
