Abstract
The utility model provides a sealing structure for a vehicle front fender. The sealing structure is used for solving the problem that a sound-absorbing and noise-lowering structure is lacked between the vehicle front fender and a vehicle body. The sealing structure is arranged in a cavity portion between the vehicle front fender and a vehicle body side portion, and comprises a bottom layer base plate, a middle sound-insulation layer and a top layer wedge absorber. The base plate is a plastic plate, the sharp portion of the wedge absorber is towards the direction of a vehicle head, and the wedge absorber is a bent cotton plate. The sealing structure can effectively prevent engine noise and ground tire noise from transmitting to a driving room, improves comfort of a driver, and provides comfortable and quite environment in a vehicle for passengers. The sealing structure can improve noise vibration and harshness (NVH) performance of the whole vehicle to reach a higher NVH standard, and is suitable for vehicle types such as cars, off-road vehicles and commercial vehicles. Besides, the sealing structure has the advantages of being simple in structure, unlimited in space, easy to produce in a large scale, low in production cost and the like.
Description
Technical field
The utility model relates to the front fender of automobile hermetically-sealed construction of a kind of automobile component, particularly sound-absorbing and noise-decreasing, belongs to automobile technical field.
Background technology
Wing is the vehicle-body outer panel that hides front vehicle wheel, and its effect is in vehicle traveling process, prevents the sandstone of being rolled by wheel, the bottom that mud splashes compartment.At present some vehicle vehicle body wing directly communicates with machinery space, and between wing and Qianmen without hermetically-sealed construction, even cause car door in closed condition, also can't intercept cabin motor noise and road surface tire and make an uproar to the transmission of operator's compartment; The part vehicle is also arranged, and the wing place is provided with panel beating sealing, but without every sound absorption materials, the sound insulation acoustically effective is still very poor
.noise passes in car, also affects the mood of chaufeur affecting occupant's ride comfort simultaneously, and long-duration driving can bring hidden danger to traffic safety.Designing and manufacturing level based on current, can't stop noise from source fully, so the obstruct of noise and absorption become the important means that reduces noise.
The utility model content
The utility model is for solving the defect of above-mentioned prior art, provides a kind of and can effectively absorb the front fender of automobile hermetically-sealed construction that motor noise and road surface tire are made an uproar.
The alleged problem of the utility model solves by the following technical programs:
A kind of front fender of automobile hermetically-sealed construction, special feature is: the sealing structure is arranged on the re-entrant portion between wing and Vehicular side body, described hermetically-sealed construction consists of bottom substrate, middle pugging and top layer wedge absorber, described substrate is plastic flagstone, the tip of described wedge absorber is towards the headstock direction, and wedge absorber is the cotton plate of bending.
Above-mentioned front fender of automobile hermetically-sealed construction, the re-entrant portion between described wedge absorber and pugging is filled by sound-absorbing material.
Above-mentioned front fender of automobile hermetically-sealed construction, the tip angle of described wedge absorber is 50-70 °.
The utility model improves for lacking sound-absorbing noise-reducing structure problem between wing and car body, and the empty cavity position between vehicle wing and Vehicular side body is provided with hermetically-sealed construction.Described hermetically-sealed construction comprises substrate, pugging and wedge absorber, the substrate of lower floor mainly plays sealing, middle pugging mainly plays sound insulation, sealing function, it is large that the upper strata wedge absorber can increase the sound absorption area, play sound absorption, wedge hollow is filled sound absorption materials, can further strengthen the wedge acoustically effective.Above-mentioned hermetically-sealed construction can effectively intercept motor noise, the road surface tire is made an uproar to the transmission of operator's compartment, improves driver and crew's comfort level, is the quiet environment inside car of driver's Creating Comfort.The utility model can promote car load NVH performance, reaches higher NVH level, is applicable to the vehicles such as car, cross-country car, commercial vehicle/comm..vehicle.In addition, the utility model also have simple in structure, be not subject to space constraint, be easy to batch manufacturing, the advantage such as cheap.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A of Fig. 1 is to view.
Attached number in the figure is as follows: 1. wing, 2. hermetically-sealed construction, 3. Vehicular side body, 4. substrate, 5. pugging, 6. wedge absorber, 7. sound-absorbing material.
The specific embodiment
Referring to Fig. 1, hermetically-sealed construction 2 described in the utility model is arranged on the re-entrant portion between wing 1 and Vehicular side body 3, plays sealing, sound insulation, sound absorption.
Referring to Fig. 1, Fig. 2, described hermetically-sealed construction consists of bottom substrate 4, middle pugging 5 and top layer wedge absorber 6.Described substrate 4 adopts plastic flagstone, mainly plays sealing function, has deadening concurrently.Middle pugging 5 adopts the good material of soundproof effect to make, and its effect is mainly sound insulation, has sealing function concurrently.Top layer is wedge absorber 6, and wedge absorber is the cotton plate of bending, and the tip of wedge is towards the headstock direction.This bending structure of wedge absorber, can increase the sound absorption area, improves acoustically effective.The tip angle of wedge absorber 6 is 50-70 °.For further strengthening the acoustically effective of wedge absorber, the triangular cavity position between wedge absorber 6 and pugging 5 adopts sound-absorbing material 7 to fill.Above-mentioned hermetically-sealed construction can effectively reduce motor noise and the road surface tire is made an uproar to the transmission of operator's compartment, reduces to drive room noise, improves vehicle NVH level and driver and crew's traveling comfort.
