Abstract
The utility model relates to a sealed sound insulating structure of a via hole of a steering column, which comprises a vehicle body plate provided with the via hole, a front wall sound insulating pad laid on the outside of the vehicle body plate, the steering column passing through the via hole and a steering column sealing cover arranged in the via hole. The junction of the steering column sealing cover and the via hole on the vehicle body plate is provided with a ring-shaped lower flange and a ring-shaped upper flange. The lower flange is laminated inside the vehicle body plate. The upper flange is laminated outside the front wall sound insulating pad. An inner convex plate and an outer convex plate which are sleeved on the steering column and are in interference fit with the excircle surface of the steering column are arranged on the steering column sealing cover on the side of the front wall sound insulating pad. The inner convex plate and the outer convex plate are arranged in an echelon mode along the axial direction of the steering column. The utility model has reasonable structure and excellent dustproof effect, particularly has the advantages of improving loss of noise transmission, effectively blocking the path of noise transmission and reducing noise in a vehicle and also has the advantage that the steering column sealing cover is formed by carrying out structure improvement on a dust cover in the prior art, does not increase cost basically, but can greatly improve the NVH performance of the whole vehicle and improves the vehicle market competitiveness.
Description
Technical field
The utility model relates to a kind of car steering tube column, especially relates to a kind of sound insulaton structure of steering column via hole.
Background technology
Acoustics encapsulation is an important factors that influences car load NVH level, how reasonably to design sealing parts such as seal ring, obstruction the acoustic seal effect of car load is played crucial effects.At present, steering column via hole place only establishes a main cover that plays dustproof effect mostly, makes the gap that exists between steering column and via hole, and the sound insulaton effect is bad, and external noise easily sees through via hole and this cover and imports in the car, gives that driver and crew bring discomfort in the car.
Summary of the invention
The utility model mainly provides a kind of sound insulaton structure of steering column via hole, and it is provided with a favorable sealing property at steering column via hole place steering column seal closure both can prevent dust, and can play the better seal soundproof effect again.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of sound insulaton structure of steering column via hole, it comprises the car body panel that is provided with via hole, be laid on the car body panel outside before enclose sound insulating pad, pass the steering column of via hole and be installed on steering column seal closure in the via hole, via hole joint portion on described steering column seal closure and the car body panel is provided with the lower flange and the upper flange of annular, lower flange fits in the car body panel inboard, encloses the outside of sound insulating pad before described upper flange fits in; Enclose sound insulating pad one side before the sealing of described steering column covers in and be provided with and be sheathed on steering column and constitute the inner convex platform and the outer lug boss of interference fit with the steering column periphery, inner convex platform and outer lug boss are the echelon setting along the steering column axial direction.There are two needs leak free noise transmission paths at the via hole place, the connecting portion of first steering column seal closure and car body panel via hole, and it two is joint portions of steering column seal closure and steering column; For the former, the lower flange of steering column seal closure and upper flange can constitute the two-stage sealing, for the latter, two boss of steering column seal closure can constitute the two-stage sealing with turning to steering column respectively, the two-stage sealing at this two place is provided with, can reach good sealing purpose, obtain soundproof effect preferably; Lower flange fits in the inboard formation of car body panel primary seal, and the outside of enclosing sound insulating pad before upper flange fits in constitutes secondary seal, and after external noise was by the primary seal decay, the noise that a part is leaked was by the further decay of secondary seal do; Be echelon inner convex platform and outer lug boss structure be set, by inner convex platform top and cooperating of steering column periphery constitute primary seal, cooperating of the top of outer lug boss and steering column periphery constitutes secondary seal; Thus, two noise transmission paths are all intercepted by secondary seal, thereby have reduced the propagation amount of external noise in car greatly.This sound insulaton structure, rational in infrastructure, be easy to realize, and soundproof effect is good.
For the ease of making and convenient the installation, as preferably, the material of described steering column seal closure is a rubber.Steering column seal closure and inner convex platform and outer lug boss, lower flange and upper flange are structure as a whole, and are easy to one-shot forming with the rubber material, and integrative-structure also is beneficial to assembling.
Be further to obtain good sound insulaton effect, as preferably, the top of described inner convex platform is made as 2-5 tunic slice structure, every tunic sheet all with steering column periphery formation interference fit.The top of multiple-structure makes to have a plurality of sealing surfaces between inner convex platform and the steering column, thereby has further improved the soundproof effect of primary seal.
With the principle that is provided with of the top multilayer film slice structure of aforementioned inner convex platform, as preferably, the top of described outer lug boss is made as 2-5 tunic slice structure, and every tunic sheet all constitutes interference fit with the steering column periphery.
Therefore, the utlity model has characteristics such as rational in infrastructure, dustproof respond well, especially have following beneficial effect:
(1) improves the noise transfer loss;
(2) effective block noise bang path;
(3) reduce internal car noise;
(4) the steering column seal closure is to form as structural development with dust boot of the prior art, does not increase cost substantially, but can significantly improve car load NVH performance, improves the vehicle market competitive power.
Description of drawings
