Description
Technical field
The utility model belongs to the vehicle body technical field of manned vehicle, is specifically related to a kind of two-box automobile back wall assembly structure.
Background technology
In the process of passenger vehicle body exploitation, consider the body structures that adopt the cancellation back buffer beam from saving the cost aspect more.But, cancelled after the back buffer beam, when the vehicle encounters rear collision, greatly increased by the damage degree, back wall structural strength and energy absorption capacity can not satisfy the safety performance requirement of colliding behind the vehicle.
Summary of the invention
The purpose of this utility model is the two-box automobile back wall assembly for the strength and stiffness that supply a kind of energy Effective Raise back wall assembly.
For achieving the above object, the two-box automobile back wall assembly of the utility model design, comprise back wall back veneer assembly and rear wall outer plate assembly, described back wall back veneer assembly comprises back wall back veneer central panel, is connected to back wall back veneer left side board and the back wall back veneer right side board at back wall back veneer central panel two ends, described back wall back veneer central panel is arranged on the sunk area at rear wall outer plate assembly middle part, and the arranged outside of described rear wall outer plate assembly has the rear wall outer plate strength beam.
The cross-sectional plane of above-mentioned rear wall outer plate strength beam is several fonts.
Above-mentioned rear wall outer plate strength beam upside is provided with the continuous projection that raises up.
The downside of above-mentioned rear wall outer plate strength beam is welded with fixed support under the rear guarantor.
Further, fixed support is L shaped under the described rear guarantor.
Again further, fixed support is provided with three side by side under the described rear guarantor, and the fixed support opening is opposite with fixed support opening under the rear guarantor who is positioned at both sides under the rear guarantor in the middle of being positioned among three.
The utility model is at the outside rear wall outer plate strength beam that increases of rear wall outer plate, Effective Raise the strength and stiffness of back wall assembly; Form enclosed cavity between back wall back veneer and outside plate, two ends connect gusset rear portion, the left and right sides simultaneously, have greatly strengthened the lateral stiffness of body tail; The upside of rear wall outer plate strength beam arranges the projection that raises up continuously, and the section of rear wall outer plate strength beam is several fonts, has further improved the strength and stiffness of rear surrounding baffle; Fixed support under protecting after the welding of rear wall outer plate strength beam has guaranteed fastened point intensity and tolerance under the rear guarantor preferably simultaneously, satisfies the requirement that the safety performance that collides behind the vehicle requires and satisfies manufacturing process.
Description of drawings
Fig. 1 is integral structure schematic diagram of the present utility model;
Fig. 2 is integral structure exploded view of the present utility model;
Among the figure: 1-back wall back veneer assembly (1.1-back wall back veneer central panel; 1.2-back wall back veneer left side board; 1.3-back wall back veneer right side board); 2-rear wall outer plate assembly; 3-rear wall outer plate strength beam (3.1-projection); Fixed support under 4-rear the guarantor.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Two-box automobile back wall assembly as shown in Figure 1, comprise back wall back veneer assembly 1 and rear wall outer plate assembly 2, back wall back veneer assembly 1 comprises back wall back veneer central panel 1.1, is connected to back wall back veneer left side board 1.2 and the back wall back veneer right side board 1.3 at back wall back veneer central panel 1.1 two ends, back wall back veneer central panel 1.1 is arranged on the sunk area 2.1 at rear wall outer plate assembly 2 middle parts, and the arranged outside of rear wall outer plate assembly 2 has rear wall outer plate strength beam 3.The cross-sectional plane of rear wall outer plate strength beam 3 is several fonts.Rear wall outer plate strength beam 3 upsides are provided with the continuous projection that raises up 3.1, and the downside of rear wall outer plate strength beam 3 is welded with fixed support 4 under the rear guarantor.Fixed support 4 is L shaped under the rear guarantor, and fixed support 4 is provided with three side by side under the rear guarantor, and fixed support 4 openings are opposite with fixed support 4 openings under the rear guarantor who is positioned at both sides under the rear guarantor in the middle of being positioned among these three.
The utility model is occuring in the rear collision process at the outside of rear wall outer plate assembly 2 captive joint rear wall outer plate strength beam 3, can effectively reduce collision damage degree, makes the collision result controlled, the strength and stiffness of back wall assembly have been increased, overall structure advantages of simple, technique realize that easily intensity is large.
