Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right The present invention is further elaborated.
As shown in Figure 5 and Figure 6, a kind of improve noise transfer function spare tyre cabin reinforcing plate structure, including spare tyre cabin 1, after Crossbeam, frame cross 2, rear crossbeam include left back crossbeam 31, the right side after crossbeam 32, frame cross 2 respectively at left back crossbeam 31, the right side after Crossbeam 32 connects composition spare tyre framework, and the edge in spare tyre cabin 1 is connected on spare tyre framework, and spare tyre cabin 1 is provided with rear reinforcing plate 11, standby Tire cabin 1 also includes being close to the left reinforcing plate 13 in spare tyre cabin type face, right reinforcing plate 14, front reinforcing plate 12, and left reinforcing plate 13 is arranged on Below spare tyre cabin 1 at the left back crossbeam 31, right reinforcing plate 14 is positioned close to below the spare tyre cabin 1 at crossbeam 32 behind the right side, Front reinforcing plate 12 is positioned close to below the spare tyre cabin 1 at frame cross 2.Left reinforcing plate 13, right reinforcing plate 14, front reinforcing plate 12 Thickness be 0.8mm.
Spare tyre cabin 1 is concave groove type structure, and left reinforcing plate 13, right reinforcing plate 14, front reinforcing plate 12 be equipped with rib, rib from Spare tyre cabin 1 top extends to bottom portion of groove, and rib forms cavity in spare tyre cabin 1 bottom surface.The extension depth of rib is preferably 10mm.
Front reinforcing plate 12 one end is connected with frame cross 2, and its other end is connected to the bottom portion of groove in spare tyre cabin 1.Spare tyre cabin 1 Including spare tyre cabin ante-chamber 15, spare tyre cabin ante-chamber 15 is the rib of front reinforcing plate 12 and the cavity of spare tyre cabin 1 formation, spare tyre cabin ante-chamber 15 bottom portion of groove and the frame cross 2 connecting spare tyre cabin 1 respectively, spare tyre cabin ante-chamber 15 is to spare tyre cabin groove from frame cross 2 The inclination cambered surface that bottom extends, front reinforcing plate 12 is connected on spare tyre cabin ante-chamber 15.
Spare tyre cabin 1 also includes crossbeam fagging 5, and crossbeam fagging is connected to the connection of crossbeam behind spare tyre cabin right side edge and the right side Place.
Crossbeam and the junction of frame cross 2 are provided with suspension point 4 afterwards.
As shown in Figure 5 and Figure 6, the present invention cancels crossbeam, is analyzed by cae, finds out the node big to Noise contribution, On front side of the bottom of spare tyre cabin 1, left side and right side increase by three pieces of reinforcing plates, reinforcing plate thickness of slab 0.8mm, be close to spare tyre cabin type face, and design There is the rib of 10mm depth, form cavity with the rib in spare tyre cabin.With crossbeam lap-joint on the right side of spare tyre cabin, increase a crossbeam newly Fagging 4, makes spare tyre cabin 1 and crossbeam connect.
The node big to Noise contribution by finding out spare tyre cabin 1, in bottom surface, difference weakness zone increases reinforcing plate and support Plate, effectively improves the strength and stiffness in spare tyre cabin, improves local mode, thus reducing in-car noise, lifts nvh Energy.
The entirety of the present invention has the beneficial effect that
1) increase 3 reinforcing plates and 1 fagging newly, instead of spare tyre cabin crossbeam, be obviously improved the intensity of total, maximum should Power reduces 120mpa, greatly reduces the cracking risk of part;
2) effectively increase the rigidity in spare tyre cabin;
3) large area improves the local mode in spare tyre cabin;
4) heel row noise generally reduces 3-5db, improves nvh performance;
