Abstract
The utility model provides a leakproofness is good, can reduce the NVH's of sealing connection department skylight aqueduct is sealed stifled. Be somebody's turn to do stifled the body that sealed stifled piece was described including the gland, the periphery of stifled piece body is equipped with the installation jack catch that is used for connecting the automobile body panel beating, and the middle part of stifled piece body is the clearing hole, and the key lies in that the one end connection of the clearing hole of a stifled body is equipped with the water piping connection portion that leads, and the other end export of clearing hole is equipped with water derivation structure, and water is derived the structure and is included one section semi -closed bellying that surrounds the clearing hole, and one section water guide inclined plane is connected to the opening of bellying. The utility model discloses a set up water and derive the structure, prevent the water cross flow through the bellying, make rainwater that the aqueduct flows can only follow the water guide inclined plane and extend the outflow datum clamp face to prevent that the rainwater from flowing the installation jack catch that blocks up the piece from the gap of aqueduct clearing hole, flows the automobile body panel beating from the gap of jack catch again and take place the seepage.
Description
Technical field
The utility model relates to automobile body part technical field, is specifically related to a kind of skylight distribution tube sealing blocking piece.
Background technology
At present, existing vehicle distribution tube water outlet sealing, adopts rubber blocking piece, distribution tube opening open mostly, and leakage statement is aobvious has impact to NVH; For improving leakage sound, designing and rubber blocking piece is replaced by plastic plug structure, the risk but the former design existence of plastic plug is leaked.As the connection structure schematic diagram that Fig. 1 is existing distribution tube blocking piece 1, in figure in three place's circles shown in be easy leakage sound place, also easily there is poor sealing shown in the left side two place circle, cause the situation of leaking.It is the structural representation of the water outlet of existing water guide blocking piece 1 as Fig. 2.In figure, A place easily flows to the installation claw of blocking piece from this gap from the rainwater that distribution tube 2 flows out, then flows to vehicle body sheet metal 3 from the gap of claw.
Summary of the invention
The purpose of this utility model is that a kind of leak tightness of proposition is excellent, can reduce the skylight distribution tube sealing blocking piece of the place NVH that is tightly connected.
According to the skylight distribution tube sealing blocking piece that the utility model provides, comprise the blocking piece body of gland shape, the periphery of described blocking piece body is provided with the installation claw for connecting vehicle body sheet metal, the middle part of described blocking piece body is passing hole, key is that one end of the passing hole of described blocking piece body is connected with distribution tube connecting portion, the other end outlet of described passing hole is provided with water derived type structure, described water derived type structure comprises one section of semiclosed lug boss surrounding described passing hole, and the opening of described lug boss connects one section of water guide inclined-plane.
Skylight of the present utility model distribution tube sealing blocking piece, by arranging water derived type structure, by the anti-sealing cross flow of lug boss, the rainwater that distribution tube is flowed out can only extend outflow datum clamp face from water guide inclined-plane, thus prevent rainwater from flowing to the installation claw of blocking piece from the gap of distribution tube passing hole, then flow to vehicle body sheet metal generation seepage from the gap of claw.
Further, described passing hole place is provided with the noise reduction part that area is slightly less than described passing hole, and by this noise reduction part, attenuation by absorption, through the acoustic energy of passing hole, reduces the NVH at this place.
Further, the periphery of described blocking piece body is provided with the noise reduction waterproof washer for being tightly connected with vehicle body sheet metal, by this noise reduction waterproof washer, while increasing the leak tightness that blocking piece body is connected with vehicle body sheet metal, also reduces NVH herein by erasure effect.
Specifically, described noise reduction waterproof washer is rubber foam packing ring.Preferably, this rubber foam packing ring choose sound absorption coefficient higher than 0.2 EPDM, when sound wave enters the noise reduction waterproof washer of this kind of material, the air in material pore and fiber can be caused to vibrate, make acoustic energy be transformed into heat energy and consume a part, playing the effect of sound-absorbing, thus reducing NVH.

Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and principle of work etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As Fig. 3,4,5, skylight of the present utility model distribution tube sealing blocking piece, comprise the blocking piece body 1 of gland shape, the periphery of blocking piece body 1 is provided with the installation claw 11 for connecting vehicle body sheet metal, the middle part of blocking piece body 1 is passing hole 12, one end of the passing hole 12 of blocking piece body 1 is connected with the connecting portion 13 of distribution tube 2, the other end outlet of passing hole 12 is provided with water derived type structure, water derived type structure comprises one section of semiclosed lug boss 14 surrounding passing hole 12, and the opening of lug boss 14 connects one section of water guide inclined-plane 15.Passing hole 12 place is provided with the noise reduction part 16 that area is slightly less than passing hole 12, and by this noise reduction part 16, attenuation by absorption, through the acoustic energy of passing hole, reduces the NVH at this place.The periphery of blocking piece body 1 is provided with the noise reduction waterproof washer 17 for being tightly connected with vehicle body sheet metal 3, by this noise reduction waterproof washer 17, while increasing the leak tightness that blocking piece body 1 is connected with vehicle body sheet metal 3, also reduces NVH herein by erasure effect.Noise reduction waterproof washer 17 is rubber foam packing ring.Preferably, this rubber foam packing ring 17 choose sound absorption coefficient higher than 0.2 EPDM, when sound wave enters the noise reduction waterproof washer of this kind of material, the air in material pore and fiber can be caused to vibrate, make acoustic energy be transformed into heat energy and consume a part, play the effect of sound-absorbing, thus reduce NVH.
