Abstract
This utility model provides a kind of metal blocking cover structure for plates of automobile blocking technological holes, blanking cover main body and annular rubber ring combine.Described blanking cover main body is stamped to form by one piece of galvanized sheet.This block galvanized sheet is stamped after molding, is circular groove in the middle part of it, and the notch of this circular groove also has a plate face, circle outer.Described annular rubber ring is bonded on the plate face, outer of circular groove notch, and is in the dorsal part of circular groove notch.Adaptable energy of the present utility model is suitable for the autobody sheet of different-thickness；Good reliability is not likely to produce deformation and comes off, more higher than traditional rubber blanking cover seals ruggedness；Saving easy for installation automobile assembling man-hour；And NVH sound insulation property is more superior can preferably stop pass-by noise into the car；And production technology is simple, advantageously reduces automobile making cost.
Description
Technical field
This utility model relates to the mechanical part structure of automobile, belongs to mechanical equipment technical field.
Background technology
In order to prevent pass-by noise from improving riding comfort in being delivered to car, noise can be passed through
Propagation path carrys out noise insulation.Machined some fabrication holes, these fabrication holes on body of a motor car
Without being plugged during assembling, noise will be delivered in car by this some holes,
Increase internal car noise and affect the riding comfort of automobile and the market competitiveness of automobile.In order to hinder
Only noise is propagated by this some holes, improves comfort property and is blocked by blanking cover on body of a motor car
This some holes carrys out noise insulation transmission.The performance of blanking cover directly affects the transmission of noise, present mesh
The blanking cover used on front automobile is much rubber blanking cover, in use, often there will be
Different problems.Such as, some blanking cover time is the most long will come off, and lost efficacy, and was because
Rubber aging is caused；Rubber blanking cover NVH sound insulation property is bad, it is impossible to well completely cut off
External noise is delivered in car；The adaptation of rubber blanking cover is indifferent, it is impossible to be suitable for different thick
The steel plate of degree, and install and expend man-hour.
It can therefore be seen that existing current blanking cover reliability in use, adaptability,
NVH performance is problematic in that, there are the needs of improvement further.
Summary of the invention
The purpose of this utility model is to solve current plates of automobile blanking cover owing to reliability is with steady
Qualitative poor, NVH sound insulation property is bad, and problem during assembly fee.
Employed technical scheme comprise that such for realizing this utility model purpose, one is used for
The metal blocking cover structure of plates of automobile blocking technological holes, by blanking cover main body and annular rubber ring group
Conjunction forms.
Described blanking cover main body is stamped to form by one piece of galvanized sheet.This block galvanized sheet is stamped molding
After, it is circular groove in the middle part of it, the notch of this circular groove also has a plate face, circle outer.
Described annular rubber ring is bonded on the plate face, outer of circular groove notch, and is in circle
The dorsal part of connected in star notch.
Further, described galvanized sheet is one piece of circular flat board.Outside described circular groove notch
It it is annular outer along plate face.
Further, described annular rubber ring is butyl rubber.
Further, the radius of gyration of described circular groove is gradually reduced to bottom land from notch.
Further, the notch of described circular groove and plate face, outer, and bottom land passes through circular arc
Shape chamfered carries out transition.
Further, described blanking cover main body and annular rubber ring are integral type structure.
Relative to prior art, this utility model has the advantages that
1, adaptable；This metal blocking cover structure can be suitable for the autobody sheet of different-thickness.
2, good reliability is not likely to produce deformation and comes off；Owing to using metallic framework, so will not
Produce aging deformation.
3, easy for installation, save automobile assembling man-hour；Use answering of butyl rubber and galvanized sheet
Closing, as long as taking out this product be directly bonded in vehicle body steel plate, being greatly shortened assembly work.
4, NVH sound insulation property is good；The sound insulation effect that metallic framework can play, adds butyl
The sealing of rubber and damping property, energy better seal fabrication hole blocks the propagation path of noise.
5, low cost；This product processes is simple, advantageously reduces the cost of automobile making.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is front view of the present utility model.
In figure: blanking cover main body 1, annular rubber ring 2, circular groove 3.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not
It is construed as the above-mentioned subject area of this utility model and is only limitted to following embodiment.Without departing from
In the case of the above-mentioned technological thought of this utility model, according to ordinary skill knowledge with used
By means, make various replacement and change, protection domain of the present utility model all should be included in
In.
Seeing Fig. 1 and Fig. 2, the present embodiment provides a kind of for plates of automobile blocking technological holes
Metal blocking cover structure, has preferable job stability, and assembling speed is fast, and the suitability is strong,
The feature that NVH sound insulation property is good, is specifically combined by blanking cover main body 1 and annular rubber ring 2
Form.
Described blanking cover main body 1 is stamped to form by one piece of circular galvanized sheet.This block galvanized sheet quilt
After punch forming, its shape is in " rounded cap " shape, and i.e. middle part is that circular groove 3 is (from outside
See, be crown), the notch of this circular groove 3 also has plate face, the outer (ring of a ring shape
Shape shade).The radius of gyration of described circular groove 3 is gradually reduced to bottom land from notch, in order to
In crown can embed vehicle body sheet metal hole, shade is fixed on panel beating reinforcement sealing simultaneously
Energy.The notch of described circular groove 3 and plate face, outer, and bottom land (crown) is by circle
Arc angling processes and carries out transition, to improve intensity and the sealing property of galvanized sheet.
Described annular rubber ring 2 is bonded on the plate face, outer of circular groove 3 notch, and place
Dorsal part in circular groove 3 notch.It is i.e. the same side with the direction that crown is protruding, it appears that
Crown is protruding from the middle part of annular rubber ring 2.
In the present embodiment, described annular rubber ring 2 is butyl rubber, owing to butyl rubber has
Viscosity and sound insulation, the effect of sealing vibration damping, can make installation more convenient, reaches to improve close
Envelope effect, decay steel plate vibration, reduces noise transmission.
Above-mentioned metal blocking cover structure has good sealing effectiveness, and sound insulation property is preferable, is subject to
Vehicular vibration impact is little, is unlikely to deform and comes off.
