Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See Fig. 1, Fig. 2, Fig. 3, a kind of expanded material baffle plate for automobile noise reduction, described baffle plate 1 bilateral symmetry, middle part is rectangle, and its two ends have a radian 3; The middle part on described baffle plate 1 oblong limit is provided with Elastic buckle 2 integrated with it, this Elastic buckle 2 is U-shaped structure, the side at its U-shaped arm place forms rough adapter plate 8, the two sides of described adapter plate 8 bend inwards the supporting blade 9 of formation two parallel vertical, draw-in groove 10 is formed between described two supporting blades 9, the guide plate 11 that a slice outwards turns down is formed after punching press on the top of described two supporting blades 9, and the both sides, bottom of described guide plate 11 are formed and can stop the hangnail that in draw-in groove 10, ash is taken out;
Described baffle plate 1 using porous type nylon resin as skeleton, and is compounded with the cavernous body 4 of inner tool acoustic(al)absorbent 6, and described acoustic(al)absorbent 6 inside has a cavity, is filled with acoustical cotton 5 in described cavity; Described cavernous body 4 inside is also provided with microwave generator assembly 7.
The utility model structure is simple, easy to use and reliable, and switching performance is good and cost is low; Baffle plate 1 is arranged in sheet metal component cavity by buckle 2, and assembly performance is better.Spongiosum inside is provided with acoustic(al)absorbent 6, described acoustic(al)absorbent 6 inside has a cavity, acoustical cotton 5 is filled with in described cavity, in the process used, partial noise can reflect back by the lateral surface of acoustic(al)absorbent 6, is absorbed in the cavity that partial noise enters acoustic(al)absorbent 6, carry out actv. process to noise through multiple reflections by the acoustical cotton 5 in cavity, greatly reduce the noise entering operator's compartment, there is good sound insulation and noise reduction effect.Spongiosum inside is provided with microwave generator assembly 7, in the process used, the microwave launched of described microwave generator assembly 7 is at spongiosum internal communication and play heat effect to spongiosum, the moisture that spongiosum inside is contained is evaporated, reduce moisture, destroy vegetative environment, the growth and breeding of anti-bacteria.
Wherein, the shape of described guide plate 11 is dovetail form, and hangnail is two tips of dovetail form.Stablize after installing and be not easy to exit, play and preferably fixing effect is installed.
Particularly, described acoustic(al)absorbent 6 is for having the sound-absorbing ball of opening.Acoustic(al)absorbent 6 is designed to spheroid, larger external surface area can be obtained, be convenient to better noise be reflected back, improve the result of use of the design.
The wall of described acoustic(al)absorbent 6 is made up of hard plastic sheet.Concrete, described hard plastic sheet can select hard PVC sheet, and not only noise reflecting effect is good, and productive costs is low.
The utility model is when assembling, first the column of plate is snapped in the draw-in groove 10 of Elastic buckle 2, hangnail makes baffle plate 1 not exit, then Elastic buckle 2 is aligned sheet metal hole prefabricated on plate, because pre-manufactured hole is oblong, can ensure to allocate the adjustment in gap, so only firmly one clap can complete baffle plate 1 and plate by installation, time saving and energy saving cost-saving, also confirms gap and the degree of tightness of assembly parts by the size at adjustment assembly position.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
