Detailed description of the invention
Reference: reinforcing plate 5-spare tyre hole, crossbeam 4-floor, 1-longitudinal beam 2-frame connecting plate 3-spare tyre hole Hole, 8-fixed plate 9-location, gripper shoe 7-floor, 6-spare tyre hole
Fig. 2-9 shows the reinforcement structure that a kind of spare tyre that the present invention provides is cheated, and described reinforcement structure includes longitudinal beam 1, car Frame connecting plate 2, spare tyre hole crossbeam 3, floor reinforcing plate 4 and spare tyre hole 5, described frame connecting plate 2 is two, and described floor is strengthened Plate 4 is two, and the two ends of described spare tyre hole crossbeam 3 connect one end of two described frame connecting plates 2, said two floor respectively Reinforcing plate 4 is relative with said two frame connecting plate 2 position respectively, and described longitudinal beam 1 is two and connects described spare tyre respectively The two ends in hole 5, said two floor reinforcing plate 4 connects described spare tyre hole 5, and the other end of said two frame connecting plate 2 is respectively Connect two described longitudinal beams 1.
Described floor reinforcing plate 4 is Z-shaped.Described floor reinforcing plate 4 is provided with fixed plate 8, and described fixed plate 8 is with described The base of floor reinforcing plate 4 and both sides side connect.The edge of described fixed plate 8 is arc transition, and described fixed plate 8 width is 20, described fixed plate 8 and described floor reinforcing plate 4 integrated injection molding.
Described spare tyre hole crossbeam 3 is U-shaped, and described spare tyre hole crossbeam 3 is provided with hole 9, location, and hole, described location 9 is located at institute Stating the bottom of spare tyre hole crossbeam 3, hole, described location 3 is three.Described spare tyre hole crossbeam 3 height is 20.
Described frame connecting plate 2 is deep U-shaped.Described frame connecting plate 2 thickness is 1.5.
Described spare tyre hole crossbeam 3 two ends by welding riveting or bolt respectively with said two frame connecting plate 2 One end connects, and described longitudinal beam 1 is two two ends being connected described spare tyre hole 5 by welding or riveting or bolt respectively, institute State two floor reinforcing plates 4 and connect described spare tyre hole 5 by welding or riveting or bolt, said two frame connecting plate 2 another One end connects two described longitudinal beams 1 respectively by welding or riveting or bolt.
The reinforcement structure in spare tyre hole, main by piece spare tyre hole crossbeam 3 of spare tyre hole bottom design, this spare tyre hole crossbeam 3 two ends are connected with frame connecting plate 2, and this frame connecting plate 2 is connected with longitudinal beam 1.Thus realize the power on the crossbeam 3 of spare tyre hole All it is effectively passed on longitudinal beam 1.The position the most corresponding with frame connecting plate 2 on top, floor, design floorboard adds Strong plate 4, cheats the connection of crossbeam 3 and the junction point position of frame connecting plate 2 and frame connecting plate 2 and longitudinal beam 1 to spare tyre Point position carries out covering and strengthens, thus realizes reinforcing the purpose of body structure.
Spare tyre hole crossbeam 3, is designed to U-shaped, and height, less than or equal to 20 millimeters, is both easy to accept the Z-direction power of spare tyre transmission Being easy to again welding, punching process character is simple simultaneously, and lightweight expense is low.
Frame connecting plate 2, is designed to deep U-shaped structure, and side is connected with spare tyre hole crossbeam 3, opposite side and longitudinal beam 1 Connect, connection floor, middle part, the thick 1.5mm of material, effectively transmit stress.
Floor reinforcing plate 4, is welded on top, floor 7, covers the junction point of spare tyre hole crossbeam 3 and frame connecting plate 2, and Frame connecting plate 2 and the junction point of longitudinal beam 1.Make junction point intensity and toughness obtain bigger raising, effectively reduce panel beating cracking Risk.
The fixed plate 8 of design all beyond the junction point 20 millimeters of spare tyre hole crossbeam 3 with frame connecting plate 2, is used for and floor 7 Welding.Be conducive to making power transmission gradually transition, effectively prevent the panel beating cracking that stress sudden change causes.
Crossbeam junction point position under spare tyre hole is connected to longitudinal beam 1 by one piece of frame connecting plate 2, and power transmission is good, structure By force, this structure can adjust the length ratio of spare tyre hole crossbeam 3 and frame connecting plate 2 according to different automobile types simultaneously, is suitable for different car Type and different performance require structure.There is high-adaptability.The floor reinforcing plate 2 on top, floor 7 connects overlap joint junction point at two, and It is extended down to weld with floor 7 outside and, has both strengthened having consolidated structure, slow down again loading process.There is certain structure innovation.
Owing to devising spare tyre hole crossbeam 3, spare tyre hole polycrystalline substance is strengthened, and intensity and toughness promotes substantially, and local becomes Shape reduces, and reduces panel beating cracking risk bottom spare tyre hole, improves structural behaviour.The spare tyre hole crossbeam size of design is little, weight Amount is light, good economy performance;.
Crossbeam 3 junction point position, spare tyre hole has upper and lower two pieces of reinforcing plates to be connected to longitudinal beam 1, and structure is higher.This structure Can avoid the occurrence of stress high, deformation is big, and panel beating ftractures, solder joint problems of crack.
This structure has the supporting role of spare tyre hole crossbeam 3, and spare tyre hole bulk strength is high, and rigidity is high, damping and robustness High;Crossbeam size is little simultaneously, light weight, good economy performance.Spare tyre hole crossbeam about 3 two-layer has reinforcement with longitudinal beam 1 junction Structure so that firm in structure, effectively reduces all kinds of cracking risks.This structure sexual valence is higher.
A kind of automobile, described reinforcement structure is located on described spare tyre hole.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention Any amendment, equivalent and the improvement etc. made within god and principle, should be included within the scope of the present invention.
