Abstract
The utility model discloses a vehicle air conditioner pipeline damping device, the device include pipy shock attenuation cover, and the wall that the shock attenuation is overlapped is followed the axial and is equipped with the slope fracture, follow the circumferencial direction symmetry between the inside and outside wall of shock attenuation cover and are equipped with two semi -ring grooves, and two semi -ring grooves that the shock attenuation was sheathe in all communicate with the slope fracture, and every semi -ring inslot that the shock attenuation is overlapped is provided with the semiorbicular piece that increases weight, the outer wall of shock attenuation cover is equipped with the annular along the circumferencial direction. This damping device suit when the air conditioner is opened, can play the effect that reduces the pipeline vibrations on vehicle air conditioner's low -pressure pipeline's hose to weaken on the bang path and spread into the noise in the car into through the pipeline.
Description
Technical field
The utility model belongs to air conditioning for automobiles field, is specifically related to a kind of pipelines of automobile air conditioner damping device,Install after this device, can shake to reach the effect that reduces internal car noise by weakening pipeline.
Background technology
Air conditioning for automobiles has become one of standard configuration of automobile at present, and air conditioning for automobiles significantly improves taking advantage of of driver and crewSit comfortableness, but the pipeline of air conditioning for automobiles unavoidably can shake in vehicle traveling process, shouldVibrations can be imported formation noise in car into, thereby affect driver and crew's riding comfort.
Utility model content
The noise forming in order to reduce pipelines of automobile air conditioner vibrations, the utility model provides a kind of air conditioning for automobilesPipeline vibration absorption device, this device is sleeved on the flexible pipe of low pressure line of air conditioning for automobiles, when air-conditioning is opened,Can play the effect that reduces pipeline vibrations, thereby weaken by pipeline and import in car on bang pathNoise.
The utility model is achieved through the following technical solutions:
A kind of pipelines of automobile air conditioner damping device, comprises the shock-absorbing sleeve of tubulose, and the wall of shock-absorbing sleeve is established verticallyThere is slant fracture, between the inside and outside wall of shock-absorbing sleeve, be along the circumferential direction arranged with two half circle groove, shock-absorbing sleeveOn two half circle groove be all communicated with slant fracture, in each half circle groove of shock-absorbing sleeve, be provided with semiorbicularWeightening finish piece; The outer wall of described shock-absorbing sleeve is along the circumferential direction provided with the annular groove for anchor ear is installed.
Further, in order to increase the weight of damping device, the material of described weightening finish piece is iron.
Further, in order to make shock-absorbing sleeve wear-resisting, the material of described shock-absorbing sleeve is rubber.
The beneficial effects of the utility model:
This damping device is sleeved on the flexible pipe of low pressure line of air conditioning for automobiles, particularly at air conditioning for automobilesThis damping device is installed in the position that on the flexible pipe of low pressure line, amplitude is larger, when air-conditioning is opened, and this dampingThe shock-absorbing sleeve of device and weightening finish piece can effectively reduce the effect of pipeline vibrations, thereby on bang pathWeaken by pipeline and import the noise in car into, improve driver and crew's riding comfort. This damping device knotStructure is simple, with low cost, damping effect is better.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of pipelines of automobile air conditioner damping device, comprises the shock-absorbing sleeve 1 of tubulose,Shock-absorbing sleeve 1 is made up to delay of rubber and is shaken. The wall of shock-absorbing sleeve 1 is provided with slant fracture 11 vertically, subtractingShake cover 1 disconnects vertically, the convenient balancing weight 2 of installing. The corresponding circular arc in the present embodiment medium dip fracture 11 placesCentral angle be 10 °. Between the inside and outside wall of shock-absorbing sleeve 1, be along the circumferential direction arranged with two half circle groove, subtractTwo half circle groove on shake cover 1 are all communicated with slant fracture 11, in each half circle groove of shock-absorbing sleeve 1, arrangeThere is semiorbicular weightening finish piece 2, in order to increase the weight of shock-absorbing sleeve 1; Meanwhile, weightening finish piece 2 is also semi-circularCan ensure that balancing weight 2 fits tightly the tube wall of flexible pipe 4. Balancing weight 2 in the present embodiment is iron block.The outer wall of described shock-absorbing sleeve 1 is along the circumferential direction provided with the annular groove 12 for anchor ear is installed, to ensure damping dressPut 3 and be unlikely to landing in long-term use.
As shown in Figure 3, the use of this damping device. Can establish at the flexible pipe of air conditioning for automobiles low pressure line 4Put multiple damping devices 3, optimization, two damping devices 3 are set in air conditioning for automobiles low pressure lineAmplitude maximum position on flexible pipe 4, and fastening by anchor ear (not shown).
The Vehicle Interior Noise of installing before and after damping device of the present utility model is tested, below passed throughMate the Contrast on effect that accelerates noise in the car in certain volume production vehicle, result is as follows:
Noise measuring point is: driver's auris dextra position
Service condition: vehicle neutral; Engine speed is by the even 4000rpm that accelerates to of idle, ACON.
Fig. 4 a does not assemble noise in noise graphics in damping device car, Fig. 4 b assembling damping device carGraphics finds out, by Fig. 4 a, and Fig. 4 b two figure contrasts, in car, noise graphics is at 2200～2400rpmBetween order noise be inhibited, can distinguish by the light and shade color contrast of circled in Fig. 4 a, Fig. 4 b.
Fig. 5 is noise total value and feature order comparison diagram in Automobile, from figure, can learn, attenuating is made an uproarValue (is shown in Fig. 5 circled) more than 15dBA, and the sense of hearing that can greatly improve noise in car with this is complained.
Hence one can see that, and pipelines of automobile air conditioner damping device of the present utility model is simple in structure, and damping effect is brightAobvious, can greatly improve driver and crew's comfortableness.
