Description
Technical field
The utility model relates to automobile vibration noise development field, refers to a kind of front windshield lower beam supporting construction for noise reduction particularly.
Background technology
In recent years for traffic protection, form mandatory rules of law requirement abroad, the domestic regulation also having recommendation.Ge great main engine plants, in order to meet increasingly strict laws and regulations requirement, take corresponding countermeasure at design phase one after another.Wherein, the front windshield lower beam structure of open cross-sections has the low feature of rigidity, has ensured that pedestrian head has good energy-absorbing when bumping against glass, and therefore this structure instead of traditional closed front windshield lower beam structure gradually.But equally because this kind of rigidity of structure is low, be easily energized thus cause Front Windshield to resonate, forming roar in obvious car, have a strong impact on vehicle noise comfort property.
Roar is a kind of phenomenon of noise in Automobile, occurs in driving engine specific rotation speeds, belongs to single-frequency noise.Engine vibration is delivered to vehicle body through suspension system, cause body panels to vibrate, the vibration of panel is coupled with spectrogram parameter again, and final formation people's ear place has the sound of constriction, client is usually caused to complain, a focus of therefore Shi Ge great main engine plants vibrating noise exploitation always.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, provides a kind of front windshield lower beam supporting construction for noise reduction, solves due to problem of thundering in the lower car caused of front windshield lower beam supporting construction rigidity.
The technical solution of the utility model is: a kind of front windshield lower beam supporting construction for noise reduction, it is characterized in that, comprise front windshield lower beam assembly, described front windshield lower beam assembly comprises top panel, stay bearing plate and lower faceplate, described top panel and lower faceplate are connected to the two ends up and down of stay bearing plate, and described lower faceplate both lateral sides extends to form roof drip along its length to middle lower portion;
Be provided with connection bracket in the middle part of described lower faceplate and between top panel, described connection bracket comprises connecting strap, and described connecting strap is arranged along front windshield lower beam assembly length direction, connects outward flange and top panel outward flange corresponding position in the middle part of lower faceplate;
Described lower faceplate right-hand component outward flange is provided with reinforced support with between corresponding top panel, and described reinforced support is arranged along front windshield lower beam assembly Width, and described reinforced support connects stay bearing plate.
Preferably, described connection bracket also comprises the engaging lug being arranged on connecting strap two ends, and engaging lug is arranged along front windshield lower beam assembly Width, and described engaging lug connects outward flange and the top panel corresponding position of lower faceplate.
Preferably, described top panel and stay bearing plate one-body molded.
Preferably, described reinforced support side is provided with Y shape reinforcement groove.
In the utility model, connection bracket strengthens the vertical stiffness of the length direction between top panel and lower faceplate, and reinforced support is arranged on the right-hand component of front windshield lower beam near bumper, and reinforced support and top panel, stay bearing plate and lower faceplate are linked to be an entirety, local front windshield lower beam supporting construction near bumper is strengthened further on the vertical stiffness of width, therefore the local vibration mode of Front Windshield is changed, both connection bracket and reinforced support are worked in coordination, and improve in the lower car caused of front windshield lower beam supporting construction rigidity problem of thundering.The optimum position of reinforced support can be determined according to the roar occurrence frequency vibration shape.The utility model increase only the rigidity of front windshield lower beam near shock absorber section, and integral rigidity increase is less, on the safety guard-safeguard of pedestrian without impact.
The utility model structure is simple, with low cost, takes into account the two-fold advantage of pedestrian protecting and noise reduction.

Wherein: 1. front windshield lower beam assembly 2. top panel 3. stay bearing plate 4. lower faceplate 5. roof drip 6. connecting strap 7. reinforced support 8. engaging lug 9. reinforced rib 10. front windshield 11. connection bracket.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, front windshield lower beam assembly 1 comprises top panel 2, stay bearing plate 3 and lower faceplate 4, top panel 2 and lower faceplate 4 are connected to the two ends up and down of stay bearing plate 3, form opening towards the U-shaped structure before car, lower faceplate 4 both lateral sides extends to form roof drip 5 along its length to middle lower portion; Top panel 2 is shaping with stay bearing plate 3 integrated punching.
As shown in Figure 2, connection bracket 11 is provided with between lower faceplate 4 and top panel 2, connection bracket 11 comprises connecting strap 6 and engaging lug 8, connecting strap 6 is arranged along the length direction of front windshield lower beam assembly 1, engaging lug 8 is arranged along the Width of front windshield lower beam assembly 1 at the two ends of connecting strap 6, as shown in Figure 3, front windshield 10 front windshield lower beam assembly 1 is equipped with, connecting strap 6 connects outward flange and top panel 2 outward flange corresponding position in the middle part of lower faceplate 4, connecting strap 6 is located at lower faceplate 4 and top panel 2 outward flange can avoid roof drip 5, in order to avoid affect draining.Engaging lug 8 is arranged along front windshield lower beam assembly 1 Width, connects the outward flange of lower faceplate 4 and top panel 2 corresponding position, and engaging lug 8 is wide at the top and narrow at the bottom trapezoidal.
