Specific embodiment
Appended drawing reference：1- longitudinal beam 2- frame connecting plate 3- spare tyre cheats the floor crossbeam 4- stiffening plate 5- spare tyre hole
6- spare tyre cheats the floor support plate 7- 8- fixed plate 9- location hole
Fig. 2-9 shows a kind of reinforcement structure in spare tyre hole provided by the invention, and the reinforcement structure includes longitudinal beam
1, frame connecting plate 2, spare tyre hole crossbeam 3, floor stiffening plate 4 and spare tyre hole 5, the frame connecting plate 2 are two, the floor
Stiffening plate 4 is two, and the both ends of spare tyre hole crossbeam 3 are separately connected one end of two frame connecting plates 2, described two
Floor stiffening plate 4 is opposite with described two 2 positions of frame connecting plate respectively, and the longitudinal beam 1 is separately connected described for two
The both ends in spare tyre hole 5, described two floor stiffening plates 4 connect the spare tyre hole 5, the other end of described two frame connecting plates 2
It is separately connected two longitudinal beams 1.
The floor stiffening plate 4 is Z-shaped.The floor stiffening plate 4 be equipped with fixed plate 8, the fixed plate 8 with it is described
The bottom edge of floor stiffening plate 4 and the connection of two sides side.The edge of the fixed plate 8 is arc transition, and 8 width of fixed plate is
20 ㎜, the fixed plate 8 and 4 integrated injection molding of floor stiffening plate.
Spare tyre hole crossbeam 3 is U-shaped, and spare tyre hole crossbeam 3 is equipped with location hole 9, and the location hole 9 is located at institute
The bottom of spare tyre hole crossbeam 3 is stated, the location hole 3 is three.The spare tyre hole 3 height of crossbeam is 20 ㎜.
The frame connecting plate 2 is deep U-shaped.The frame connecting plate 2 is with a thickness of 1.5 ㎜.
The both ends of spare tyre hole crossbeam 3 by weld or rivet or bolt respectively with described two frame connecting plates 2
One end connection, the longitudinal beam 1 are two by welding or riveting or bolt is separately connected the both ends in spare tyre hole 5, institute
Two floor stiffening plates 4 are stated by welding or riveting or being bolted spare tyre hole 5, described two frame connecting plates 2 it is another
One end is by welding or riveting or bolt is separately connected two longitudinal beams 1.
The reinforcement structure in spare tyre hole mainly designs a spare tyre hole crossbeam 3 by cheating bottom in spare tyre, which cheats crossbeam
3 both ends are connect with frame connecting plate 2, which is connected with longitudinal beam 1.To realize the power on the crossbeam 3 of spare tyre hole
It is all effectively passed on longitudinal beam 1.Simultaneously in floor top position corresponding with frame connecting plate 2, designs floorboard and add
Strong plate 4, to spare tyre hole crossbeam 3 and the tie point position of frame connecting plate 2 and the connection of frame connecting plate 2 and longitudinal beam 1
Point position carries out covering reinforcement, to realize the purpose for reinforcing body structure.
Spare tyre cheats crossbeam 3, is designed to U-shaped, is highly less than or equal to 20 millimeters, both convenient for the Z-direction power of undertaking spare tyre transmitting
Again convenient for welding, while punching process character is simple, and light-weight expense is low.
Frame connecting plate 2 is designed to deep U-shaped structure, and side is connect with spare tyre hole crossbeam 3, the other side and longitudinal beam 1
Connection, middle part connect floor, expect thickness 1.5mm, effectively transmitting stress.
Floor stiffening plate 4 is welded on 7 top of floor, and covering spare tyre cheats the tie point of crossbeam 3 and frame connecting plate 2, and
The tie point of frame connecting plate 2 and longitudinal beam 1.So that tie point intensity and toughness is obtained larger raising, metal plate cracking is effectively reduced
Risk.
The fixed plate 8 of design is used for and floor 7 beyond spare tyre hole crossbeam 3 and 20 millimeters of tie point of frame connecting plate 2
Welding.Be conducive to make power transmission gradually transition, the cracking of metal plate caused by effectivelying prevent stress to be mutated.
Crossbeam tie 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, while the structure can adjust the length ratio that spare tyre cheats crossbeam 3 and frame connecting plate 2 according to different automobile types, be applicable in different vehicles
Type and different performance require structure.With high-adaptability.Tie point is overlapped at the connection of floor stiffening plate 2 two on 7 top of floor, and
And be extended down to welded with floor 7 outside, not only reinforce having consolidated structure, but also slow down loading process.With certain structure innovation.
Due to devising spare tyre hole crossbeam 3, spare tyre hole bottom structure is enhanced, and intensity and toughness is promoted obviously, and part becomes
Shape reduces, and reduces spare tyre hole bottom metal plate cracking risk, improves structural behaviour.The spare tyre hole crossbeam size of design is small, weight
Amount is light, good economy performance；.
Spare tyre hole 3 tie point position of crossbeam has upper and lower two pieces of stiffening plates to be connected to longitudinal beam 1, and structure is stronger.The structure
It can avoid the problems such as stress is high, and deformation is big, metal plate cracking, solder joint cracks occur.
The structure has the supporting role of spare tyre hole crossbeam 3, and spare tyre cheats integral strength height, and rigidity is high, damping and robustness
It is high；Crossbeam size is small simultaneously, light weight, good economy performance.There are reinforcement in spare tyre hole 3 upper layer and lower layer of crossbeam and 1 junction of longitudinal beam
Structure, so that it is firm in structure, all kinds of cracking risks are effectively reduced.The structure sexual valence is relatively high.
A kind of automobile, the reinforcement structure are set on spare tyre hole.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
