Description
Technical field
The utility model relates to a kind of design of Sealing Structure, particularly a kind of vehicle steering column hermetically-sealed construction of strengthening the sealing of vehicle dash panel steering column passing hole and sound insulation property.
Background technology
Steering column passing hole perforated area on front wall panel beating is comparatively large, if sealing and sound insulation property not up to standard, water and noise leakage can be caused, greatly affect quality and the noise traveling comfort of product.Existing steering column hermetically-sealed construction many employings individual layer rubber structure parcel steering swivel system transmission shaft, is pressed in outside panel beating 2 in the junction with automobile body front wall metal plate 2 by interference fit, as shown in Figure 1.This mode easily makes rubber sheath 1 and panel beating 2 depart from vehicle travel process, produces water or noise leakage thus.And due to the restriction of rubber thickness, the sound insulation property of this mode is also very undesirable.
In order to solve above-mentioned technology Problems existing, Chinese patent " a kind of seal noise insulation structure of steering column via hole " (authorizing publication number: CN201626471U) discloses a kind of seal noise insulation structure of steering column via hole, it comprises the car body panel being provided with via hole, be laid in the front wall sound-isolation pad on outside car body panel, through steering column and the steering column seal closure that is installed in via hole of via hole, via hole joint portion in described steering column seal closure and car body panel is provided with lower flange and the upper flange of annular, lower flange fits in inside car body panel, described upper flange fits in the outside of front wall sound-isolation pad, the sealing of described steering column covers in front wall sound insulating pad side and is provided with and is sheathed on steering column and forms inner convex platform and the outer lug boss of interference fit with steering column periphery, and inner convex platform and outer lug boss are echelon setting along steering column axial direction.Although strengthened relative to its soundproof effect of prior art, manufacturing process is complicated, reliability is not high.
Utility model content
The purpose of this utility model is to provide one can meet water and air-tightness requirement, greatly can promote again the vehicle steering column hermetically-sealed construction of sound insulation property.
For solving the problems of the technologies described above, vehicle steering column hermetically-sealed construction, comprises lower jacket body and the flange of articulating at described sheath body bottom portion edge; The side of described flange laminating vehicle body sheet metal, described flange has bolt hole; Be provided with seal cover cap in the side of described vehicle body sheet metal, described seal cover cap and described flange are arranged about described vehicle body sheet metal homonymy; Described seal cover cap comprises: boss, and described boss is corresponding with the position of the passing hole on described vehicle body sheet metal; Described boss is provided with perforate; And adapter plate, described adapter plate articulating is at described boss bottom edge, and described adapter plate and described flange are fitted; Wherein said flange is arranged between described vehicle body sheet metal and described adapter plate, and described flange, described vehicle body sheet metal and described adapter plate are bolted.
Preferably, described lower jacket is made up of steering column connecting portion, annular groove and ring wall surface from down to up.
Preferably, quieter material is provided with in the inner side of described boss and steering column transmission shaft contact surface.
Preferably, described quieter material is felts material.
Preferably, the material of described sheath body, described flange and described seal cover cap is rubber.
The utility model vehicle steering column hermetically-sealed construction not only solves vehicle in operational process due to the water of lower jacket distortion generation or the leakage problem of noise, and owing to defining double-wall construction between lower jacket and seal cover cap, thus greatly improve sound insulation property herein.The flange stretched in car and vehicle body sheet metal and seal cover cap are bolted by this design, and reliability is higher, and to manufacture and mounting process less demanding, easily realize.The groove design of lower jacket can strengthen its fatigue resistance greatly.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model vehicle steering column hermetically-sealed construction is described in further detail.
As shown in Figure 2 and Figure 3, the utility model vehicle steering column hermetically-sealed construction comprises lower jacket and seal cover cap.Lower jacket is made up of at the flange 2 of sheath body 1 bottom margin sheath body 1 and articulating, sheath body 1 is arranged on the side of vehicle body sheet metal 3, sheath body 1 itself is made up of steering column connecting portion 10 from down to up and ring wall surface 11, sheath body 1 time edge is tightened together by interference fit with steering column, and flange 2 is through passing hole 5 on vehicle body sheet metal 3, fit with the other side of vehicle body sheet metal 3, be enclosed within 3 welded nuts of front wall panel beating, realize good dust-proof effect, and can block noise bang path effectively, reduce internal car noise.
Seal cover cap is made up of boss 4 and adapter plate 7.The position of the boss 4 of seal cover cap is corresponding with the position of passing hole 5, has perforate 6 at boss 4, and the tail end of steering column coordinates with the inwall of perforate 6.Adapter plate 7 articulating is at boss 4 bottom margin, and laminating is laid on flange 2, and now vehicle body sheet metal 3, flange 2 and adapter plate 7 are close together, thus decrease external noise greatly to the propagation amount in car, increases the sound insulation property of passing hole 5.And vehicle body sheet metal 3, flange 2 and adapter plate 7 are also closely linked together by bolt 8, further increase the reliability of sealing.
Lower jacket and seal cover cap are all be easy to one-shot forming by quality of rubber materials, and Split type structure is not only conducive to assembling, and as flexible material, rubber can realize better fitting effect with vehicle body sheet metal 3, ensure that the effect of sound insulation.
Further, at the groove 9 of the enough motion spaces of the guaranteed steering swivel system of the Front-end Design of sheath body 1, the fatigue-resistance characteristics of Rubber Parts can be increased thus.
Meanwhile, produce abnormal sound in order to avoid seal cover cap and tubing string contact surface rub, the contact surface of the tail end of steering column and the inwall of perforate 6 adheres to one deck felts material.
The utility model vehicle steering column hermetically-sealed construction not only solves vehicle in operational process due to the water of lower jacket distortion generation or the leakage problem of noise, and owing to defining double-wall construction between lower jacket and seal cover cap, thus greatly improve sound insulation property herein.The flange stretched in car and vehicle body sheet metal and seal cover cap are bolted by this design, and reliability is higher, and to manufacture and mounting process less demanding, easily realize.The groove design of lower jacket can strengthen its fatigue resistance greatly.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
