This utility model can be for all vehicles, and equipment is without transformation, simple and convenient, only need to be equipped with corresponding punching cutter.
Accompanying drawing explanation
Referring to the drawings, disclosure of the present utility model will be apparent.It is to be appreciated that these accompanying drawings are intended solely for illustrative purposes, and it is not intended to protection domain of the present utility model is construed as limiting.In figure:
Fig. 1 shows relief valve position at car boot railway carriage or compartment；
Fig. 2 is the end-state of the relief valve sound insulating pad according to a kind of embodiment of the present utility model；
Fig. 3 be the relief valve sound insulating pad in Fig. 2 flat board felt die cutting after state；And
Fig. 4 is the process that the flat board felt in Fig. 3 is folded into relief valve sound insulating pad.
Detailed description of the invention
Explain detailed description of the invention of the present utility model with reference to the accompanying drawings.In the drawings, identical reference represents identical or corresponding technical characteristic.
Fig. 1 shows relief valve position at car boot railway carriage or compartment.It can be seen that in the illustrated embodiment, car boot railway carriage or compartment can be respectively provided with the position 1 of an installation relief valve in both sides.The relief hole that this position is rectangle in diagram.It will be seen that, other shapes of hole can also be used to realize pressure release in other optional embodiment.
Fig. 2 is the end-state of the relief valve sound insulating pad 10 according to a kind of embodiment of the present utility model.This relief valve sound insulating pad 10 is made up of flat board felt.It can be seen that this relief valve sound insulating pad has the shape of solid, being suitable to be arranged on matchingly in the installation site 1 in car boot railway carriage or compartment, its bottom surface 11 can effectively cut off the noise path at automobile relief hole.It can be seen that each side 12 of relief valve sound insulating pad along bottom surface 11 periphery around and integral with plane perpendicular landform.The mounting means of relief valve sound insulating pad can take bolt connection or bonding (such as but not limited to gluing) etc. according to concrete installation interface situation, by each engagement sides to automobile relief hole.So, the most mounted sound insulating pad can be fitted well with the installation site in car boot railway carriage or compartment, directly uses installation at general assembly scene, it is possible to effectively cuts off noise path, provide good acoustical behavior.
It will be seen that, although the relief valve sound insulating pad of three-dimensional shape shown in figure 2 is rectangular parallelepiped form, but, when car boot railway carriage or compartment installation site uses the form such as circular port, other polygonal hole, relief valve sound insulating pad can be folded into corresponding stereogenic too.As a example by rectangular relief valve sound insulating pad, its folding manufacturing process is described below in conjunction with Fig. 3 and Fig. 4.
Fig. 3 be the relief valve sound insulating pad in Fig. 2 flat board felt die cutting after state.In the drawings, dotted portion represents the junction surface between each side 12 and bottom surface 11, its weak portion formed on flat board felt, and flat board felt can fold along these weak portions, then obtains desired three-dimensional shape.Such as, the material at these weak portions can be with incomplete cut-off, and cutting thickness such as can be the 50% ~ 70% of material gross thickness, it is simple to manual folding.
As it can be seen, be respectively formed with Plug Division 13 or grooving 14 on adjacent side, insert 13 and together thus form stable three-dimensional shape in grooving 14 realizing each engagement sides folding Hou Shi Plug Division, each side.Bonding mode can also be used；It is bonded to each other by the side that each is turned up and also is able to form stable three-dimensional shape.According to the example in figure, the width for the grooving of grafting can be slightly less than material gross thickness, the most smaller 2 ~ 3 millimeters, so that reach suitable interference fit after Zhe Dieing.The length of grooving can be advisable in 30% ~ 70% length of the length of side without being strict with.It will be seen that, the parameter such as concrete size positions selects to refer to concrete peripheral interface.
Fig. 4 is the process that the flat board felt in Fig. 3 is folded into relief valve sound insulating pad.
In the diagram, step a represents the flat board felt after punching press, and it includes a bottom surface and four sides I, II, III, IV.In stepb, first side I is turned up.In step c, side I has folded to suitable position, is substantially perpendicular to bottom surface.Side II is turned up by step d, a Plug Division on the II of side is inserted in the grooving of side I.In step e, show that I and II grafting in side is complete.Then, continue to fold in position side III and IV in step f, g, h, and the grafting of the most each side is good, the three-dimensional relief valve sound insulating pad shown in pie graph 2.
Those skilled in the art it will be seen that, teaching based on the application, it is also possible to expects using alternate manner to be fixed each side of flat board felt and form three-dimensional shape.Such as, each side can the shape shown in bonding one-tenth Fig. 2.Equally, according to hole shape concrete on automotive back railway carriage or compartment, it is also possible to constitute the three-dimensional relief valve sound insulating pad with circle, other polygon prismatic shapes in a similar fashion.
Relief valve sound insulating pad provided by the utility model uses the low cost process of the direct punching molding of flat board felt materials, folding or the stereomodel of bonding one-tenth needs in conjunction with artificial, stock utilization is high, and manual operation is convenient, acoustical behavior is excellent, has reached the optimization of cost and performance；Simultaneously can be for all vehicles, equipment, without transformation, only need to be equipped with corresponding punching cutter.
Technical scope of the present utility model is not limited solely to the content in described above, those skilled in the art can be on the premise of without departing from this utility model technological thought, above-mentioned embodiment is carried out many variations and modifications, and these deformation and amendment all should be worked as and belonged in scope of the present utility model.
