Description
Technical field
The utility model relates to technical field of automobile parts, refers to especially a kind of automobile exhaust pipe noise-reducing structure.
Background technique
Automobile is the important traffic tool of one the most universal in modern society, its by engine combustion gasoline to produce power band motor vehicles bodies, and at least one venting gas appliance being communicated with engine is set on vehicle, and venting gas appliance is mainly by the high-temp waste gas after burning, from in engine or cylinder through discharge manifold, outlet pipe and silencing apparatus, finally be discharged in air by tail pipe, it has two Main Functions, the firstth, the waste gas of high temperature is discharged from engine or cylinder, in order to avoid affect the running of engine or cylinder, the secondth, the noise that utilizes silencing apparatus etc. that the waste gas of these High Temperature High Pressure is produced reduces to minimum, gas expansion in normal engine or cylinder is very large, while entering venting gas appliance, its pressure is still very high, therefore in the time having gas through discharge manifold at every turn, capital impacts ripple.Shock wave appearance approximately per minute sometimes several thousand times, the noise sending makes people beyond affordability, therefore must be processed through venting gas appliance.
But, the venting gas appliance of prior art is mostly the sound insulation element such as silencing cotton, dividing plate is set on toxic emission route, or by the bending of toxic emission route, shunting, noise volume while reducing toxic emission, but absorbing noise system with sound insulation element needs to use quite a lot of sound insulation element just to there will be effect, toxic emission route, through bending, shunting, is to cause air displacement to decline again, affects engine usefulness.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of automobile exhaust pipe noise-reducing structure, and it can improve air displacement makes engine usefulness bring into play and save the sound insulation element such as silencing cotton, dividing plate completely to reduce costs.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of automobile exhaust pipe noise-reducing structure, described noise-reducing structure is sheathed on the body of outlet pipe, described body is provided with suction port and air outlet, on described body upper side wall, be arranged with pod apertures, described pod apertures is near suction port, and described noise-reducing structure comprises the reflector being sheathed on body, in described reflector, be provided with multiple channel parts, described channel part is connected with body by pod apertures.
Wherein, described channel part is separated by the dividing plate of being located in reflector.
Wherein, between adjacent described dividing plate, be provided with baffle plate.
Wherein, described body is straight-through tube.
The beneficial effect of technique scheme of the present utility model is as follows:
1. because body is straight-through tube, reach the effect of high air displacement.
2. adopt demarcation strip that reflector is divided into some channel parts, save cost, there is practicability.
3. body, diversion division and channel part match, and with the mutual collision principle that the rebounds source that abates the noise, reach the effect of eliminating sympathetic response, reducing noise.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment's automobile exhaust pipe noise-reducing structure;
Fig. 2 is the principle schematic of the utility model embodiment's automobile exhaust pipe noise-reducing structure.
Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, a kind of automobile exhaust pipe noise-reducing structure that the utility model embodiment provides, described noise-reducing structure is sheathed on the body 1 of outlet pipe, described body 1 is provided with suction port 11 and air outlet 12, on described body 1 upper side wall, be arranged with pod apertures 2, described pod apertures 2 is near suction port 11, and described noise-reducing structure comprises the reflector 3 being sheathed on body 1, in described reflector 3, be provided with multiple channel parts 31, described channel part 31 is connected with body 1 by pod apertures 2.Described channel part 31 is separated by the dividing plate 32 of being located in reflector 3.Between adjacent described dividing plate 32, be provided with baffle plate 33.Described body 1 is straight-through tube.
As shown in Figure 2, when the waste gas with noise source enters body 1 when interior from inlet end 11, most of waste gas is by this pod apertures 3 and in inlet passage portion 31, and move and reflect along channel part 31, and then waste gas movement direction generation 180 degree are turned to, and waste gas refluxes along this channel part 31, once again by pod apertures 3 and flow back in body 1, again because this pod apertures 3 is corresponding setting, mutually bump therefore waste gas streams return pipe body 1 is rear, and also there is collision mutually simultaneously and then mutually eliminate in the noise source that waste gas is carried under one's arms, payment, and waste gas behind the source of abating the noise is along body 1 direct expedite discharge from air outlet 12.
The beneficial effect of technique scheme of the present utility model is as follows:
1. because body is straight-through tube, reach the effect of high air displacement.
2. adopt demarcation strip that reflector is divided into some channel parts, save cost, there is practicability.
3. body, diversion division and channel part match, and with the mutual collision principle that the rebounds source that abates the noise, reach the effect of eliminating sympathetic response, reducing noise.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
