Description
Technical Field
The utility model relates to the field of automotive technology, specifically be an motormeter dish structure with sound insulation effect.
Background
In the driving process of an automobile, an engine is the largest source of noise, and if excessive noise enters a cab, the driving experience of a driver is seriously influenced. The automobile instrument panel is positioned between an engine and a driver, and engine noise easily penetrates through the automobile instrument panel and directly enters a cab to influence the driving of the driver, so that how to invent the automobile instrument panel structure which has good sound insulation effect and avoids the noise generated by the engine from influencing the driving of the driver is a problem to be solved urgently by people in the technical field at present.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a motormeter dish structure with effect gives sound insulation to solve the present motormeter dish that proposes among the above-mentioned background art and inhale sound effect poor, engine noise passes motormeter dish easily, causes the problem of influence for driver's driving.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an motormeter dish structure with sound insulation effect, includes the panel board body, open at the top of panel board body has the instrument mounting groove, the lateral wall all opens the connecting block inserting groove about the panel board body, the bolt fastening hole has all been opened to the top left and right sides of panel board body, and the bottom of bolt fastening hole runs through in the bottom of connecting block inserting groove, there is last acoustic celotex board bottom of panel board body through bolt fastening mounting, there is lower acoustic celotex board bottom of going up the acoustic celotex board through bolt fastening mounting, there is the sound-absorbing sound-insulating housing bottom of going up the acoustic celotex board through bolt fastening mounting in the bottom left and right sides all, the sound-absorbing sound-insulating housing's bottom and the lateral wall of controlling have all evenly opened the sound-absorbing.
Preferably, the upper baffle plate is a lead plate.
Preferably, the lower baffle plate is a polyurethane fiber baffle plate.
Preferably, the sound-absorbing board is a wave crest sound-absorbing cotton layer.
Compared with the prior art, the beneficial effects of the utility model are that: this kind of motormeter dish structure with effect gives sound insulation, reasonable in design, the practicality is strong, adopts to inhale sound-proof housing and abatvoix and can weaken the sound absorption that the engine produced, adopts acoustic celotex board and acoustic celotex board down, can be with the further separation of the sound that weakens, and the effectual noise that has reduced the engine production causes the influence to the driver drives.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of the present invention.
In the figure: 1 panel board body, 2 instrument mounting grooves, 3 connecting block inserting grooves, 4 bolt fixing holes, 5 upper acoustic celotex boards, 6 lower acoustic celotex boards, 7 acoustic panels, 8 acoustic sound-absorbing sound-proof covers, 9 acoustic holes.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides an motormeter dish structure with sound insulation effect, includes panel board body 1, open at panel board body 1's top has instrument mounting groove 2, lateral wall has all opened connecting block inserting groove 3 about panel board body 1, bolt fastening hole 4 has all been opened to panel board body 1's the top left and right sides, and the bottom of bolt fastening hole 4 runs through in the bottom of connecting block inserting groove 3, there is last acoustic celotex board 5 bottom panel body 1 through bolt fixed mounting, it has lower acoustic celotex board 6 to go up the bottom of acoustic celotex board 5 through bolt fixed mounting, there is sound absorption sound-proof housing 8 bottom both sides about going up the bottom of acoustic celotex board 5 through bolt fixed mounting down, sound absorption hole 9 has all evenly been opened to the lateral wall about with in the bottom of sound absorption housing 8.
Wherein, go up acoustic celotex board 5 and be the stereotype, acoustic celotex board 6 is polyurethane fiber acoustic celotex board down, and stereotype and polyurethane fiber acoustic celotex board can carry out the separation to sound, weaken the propagation of sound, acoustic board 7 inhales the cotton layer of sound for the crest, and the crest inhales a sponge that the cotton layer of sound formed the unsmooth wave shape of one side, and its inside is full of tiny space and half-opening structure, and the sound wave energy that can a large amount of absorptions and penetrate plays the attenuation to the sound wave.
Specifically, during the use, the staff inserts panel board body 1 in motormeter dish mounting groove, make the connecting block inserting groove 3 that the connecting block of the left and right sides was seted up to the panel board body 1 left and right sides in the motormeter dish mounting groove, later the staff inserts the bolt in two bolt fastening holes 4, later the knob bolt, it is fixed with panel board body 1 to make the connecting block, when the car moves, the sound that the engine produced passes earlier and inhales sound hole 9, reach and inhale in inhaling sound-proof housing 8, later sound absorption board 7 absorbs the sound that the engine produced and weakens, later the sound that weakens is through lower acoustic celotex board 6 and last acoustic celotex board 5 separation again, further weaken the propagation of noise, later the sound that reachs the driver's driver is just very little, can not cause the influence to the driver.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
