Description
Technical field
The invention belongs to technical field of automotive upholstery, are related to a kind of composite sound-absorbing felt being easily assembled.
Background technique
Deadener felt is a kind of common automotive upholstery, can reduce noise pollution.Existing deadener felt is mostly
Composite construction mainly includes the re-coating layer of EPDM (ethylene propylene diene rubber) material and the felt of PET (poly terephthalic acid) material
Layer, and re-coating layer and felt layers carried out by way of ultrasonic bonding it is compound.
The process of ultrasonic bonding is main are as follows: using workpiece surface it is high-frequency friction make it is intermolecular rapidly generate heat,
When this heat melts workpiece enough, stop ultrasonic wave hair vibration, workpiece surface is solidified by melting at this time, completes Compound Machining.
This complex method is primarily present following problems:
1, it will lead to recoating layer surface when heat is excessively high to be heated and generate and be charred taste, with current each main engine plants to smell score value
Requirement run counter to.
2, there is welding offset, maintenance cost at present still in automation initial stage, in welding process in ultrasonic welding technique
The disadvantages of high, increases the production cost of part.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide it is a kind of be easily assembled answer
Close deadener felt.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of composite sound-absorbing felt being easily assembled, the composite sound-absorbing felt include re-coating layer, are arranged in re-coating layer
Felt layers and the retention mechanism being arranged between re-coating layer and felt layers, the retention mechanism include that bottom is plugged in recoating
Layer inside the first fastener and be embedded inside felt layers and it is compatible with the top of the first fastener second fastening
Part.Felt layers are placed in re-coating layer by compound tense, and by the second fastener to compressing after just corresponding first fastener, with
By the second fastener together with the first fastener fixing assembling, and then realize the quick compound assembly of re-coating layer and felt layers.
Further, first fastener includes the glue nail pedestal being embedded inside re-coating layer and is arranged in glue nail
The top of glue nail on pedestal, glue nail protrudes from the upper surface of re-coating layer.For glue nail pedestal for fixing glue nail, glue nail can be with
Second appended claims.
Further, second fastener includes the sleeve being embedded inside felt layers, and the bottom of the sleeve opens up
Have and follows closely compatible glue nail jack with glue.The top insertion glue of glue nail is followed closely into jack, by the first fastener and the second fastener
Fixing assembling is together.
Further, the side of glue nail is circumferentially uniformly distributed multiple inclination inserted sheets, and the glue follows closely jack
Inner wall be equipped with and the compatible inclination baffle of inclination inserted sheet.Second fastener is pressed on the first fastener, follows closely glue
Top constantly to glue nail jack in move；After tilting inserted sheet across inclination baffle, release to the secondth fastener
Pressing, at this time felt layers elastic-restoring force effect under, the second fastener with respect to the first fastener counter motion, at this time due to
It tilts baffle to act on the locking of inclination inserted sheet, limits the continuation counter motion of the second fastener and the first fastener, in turn
Realize the fixing assembling of the first fastener and the second fastener.
Further, the inclination inserted sheet is flexible inclination inserted sheet.Tilting inserted sheet has certain flexibility, when glue nail
Top is constantly moved into glue nail jack, and inclination inserted sheet can be fitted in glue nail side under the compressing of inclination baffle, so as to glue
Nail continues to move to glue nail jack depths；After tilting inserted sheet and moving to the top for tilting baffle, due to departing from inclination baffle
Compressing, make tilt inserted sheet restore, and with inclination baffle cooperation realize it is non-return.
Further, it is equipped in glue nail jack and follows closely compatible glue storage chamber with glue.It is set in glue storage chamber
There is glue, when the first fastener and the second fastener are installed in place, glue outflow in glue storage chamber, and it is distributed in first
Between fastener and the second fastener, composite effect is further strengthened.
Further, the bottom of the glue storage chamber is equipped with sealing diaphragm, the top of the described glue nail be equipped with it is close
The compatible tip of sealer piece.When the top of glue nail moves in place in glue nail jack, tip punctures sealing diaphragm, makes glue
Glue outflow in storage chamber；After a certain period of time, glue solidifies, and the first fastener and the second fastener are tightly secured in one
It rises.
Further, uniformly distributed between the re-coating layer and felt layers to have multiple retention mechanisms, so as to by re-coating layer
It is combined with each other completely with felt layers.
Compared with prior art, the invention has the characteristics that:
It 1), can be by the way of mechanical fasteners by re-coating layer by the way that retention mechanism is arranged between re-coating layer and felt layers
It is combined with each other with felt layers, finally obtains composite sound-absorbing felt, avoid coke present in traditional ultrasonic bonding mode
The problems such as paste and welding offset, product quality is substantially increased, product cost is reduced；
2) except through the locking fit system of inclination inserted sheet and inclination baffle between the first fastener and the second fastener
It is outer to carry out fastening installation, glue further also is carried out to the first fastener and the second fastener using the glue in glue storage chamber
It is viscous, so that the first fastener and the second fastener is stably installed together, and then improve the use of composite sound-absorbing felt
Service life.
