Abstract
The utility model relates to a device of making an uproar falls in vehicle air conditioner installs the balancing weight on the rubber tube in its air conditioner pipeline, the balancing weight is formed to closing by two and half circular snap rings, and two and half circular snap rings are to the internal diameter that the closes external diameter phase -match with the rubber tube. The utility model discloses hose part hoop cover balancing weight at former vehicle air conditioner pipeline need not to arrange alone the resonant cavity space, has reduced the vibration noise that is produced by compressor natural frequency by a wide margin, has promoted the idling NVH performance of vehicle air conditioner system. And the balancing weight is processed and material cost is extremely low, need not to the new die sinking utensil of product, and the similar method of accessible is implemented to any vehicle, and the commonality is good.
Description
Technical field
This utility model belongs to automotive air-conditioning system, concretely relates to a kind of car air-conditioner denoising device.
Background technology
In recent years, along with the requirement of ride comfort is improved constantly by user, user is no longer only limitted to the comfortable of temperature to the requirement of air conditioning system, requirement to NVH performance gradually steps up, especially under vehicle idling operating mode, owing to not having wind noise, environment inside car is the quietest, and ride comfort will be had an immense impact on by the noise that at this moment air conditioning system produces.
The idling noise of air conditioning system is generally transferred to crew module by the pulsations of compressor by air-conditioning duct.The conventional means solving this problem at present in industry is: redesign air-conditioning duct, connect in air-conditioning duct a resonator cavity or deafener, thus realizes the effect of noise reduction.But this way processing cost is higher, needs independent mould, and versatility is bad, needing individually to reserve the arrangement space of resonator cavity or deafener, add the soldering processes difficulty of air-conditioning duct, so adding disclosure risk, more cannot be applied to after market.
Utility model content
The purpose of this utility model is, produces satisfactory counter weight device with minimum cost and difficulty of processing, and directly installs additional on former car air-conditioning duct, thus realizes the effect of noise reduction, promotes the idling NVH performance of automotive air-conditioning system.
This utility model realizes above-mentioned purpose by the following technical solutions.Car air-conditioner denoising device, the sebific duct in air-conditioning duct is provided with balancing weight, and described balancing weight is involuted by two semicircle shape snap rings, and the involutory internal diameter of said two semicircle shape snap ring matches with the external diameter of sebific duct.
The extrados of described snap ring is provided with groove.
This utility model is at the hose segment cuff balancing weight of former car air-conditioner pipeline, it is not necessary to individually arranges resonator cavity space, considerably reduces the vibration noise produced by compressor natural frequency, improve the idling NVH performance of automotive air-conditioning system.And balancing weight processing and cost of material are extremely low, it is not necessary to for the new mold of product, can be implemented for any vehicle by similar approach, versatility is good.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of this utility model structure；
Fig. 2 is the schematic diagram that this utility model uses installment state.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.Seeing Fig. 1 and Fig. 2, car air-conditioner denoising device, the sebific duct 2 in air-conditioning duct 1 is provided with balancing weight 3, balancing weight 3 is involuted by two semicircle shape snap rings 31, and the extrados of snap ring 31 is provided with groove 32.According to the rotating speed of compressor during idling and the primitive form of compressor, extrapolate the vibrations fundamental frequency of this system compressors, select counter weight device credit rating according to vibrations fundamental frequency.Groove 32 periphery being banded on 3 two semicircle shape snap rings 31 of balancing weight with plastic tape again is fixed, and makes balancing weight 3 be fixed on sebific duct 2 at vibration, it is achieved that significantly reducing of idling noise.Balancing weight 3 uses common No. 45 rod iron trucks to go out the counter weight device of respective quality grade, and is cut into two semicircle shapes.The diameter of bore formed after two semicircle shape snap rings 31 are involutory matches with sebific duct 2 external diameter in air-conditioning duct 1.
Claims (2)
1. car air-conditioner denoising device, it is characterised in that be provided with balancing weight on the sebific duct in air-conditioning duct, described balancing weight is involuted by two semicircle shape snap rings, and the involutory internal diameter of said two semicircle shape snap ring matches with the external diameter of sebific duct.
Car air-conditioner denoising device the most according to claim 1, it is characterised in that the extrados of described snap ring is provided with groove.
