Abstract
The utility model relates to a vacuum pump sound-proof housing assembly, vacuum pump sound-proof housing assembly inhale the sound cotton by sound-proof housing body and inboard attachement and constitute, wherein the sound-proof housing body comprises 5 smooth connections of face, be equipped with a round hole on it, a slotted hole and a bolt hole, and then through two bolts and a bolt and vacuum pump support connection, thereby semi-enclosed sound-proof housing body partly surrounds the parcel with the vacuum pump and lives, this vacuum pump sound-proof housing assembly has reduced and has spread into the interior vacuum pump noise of operation of driver's cabin into, the life of vacuum pump has been guaranteed, the cost is lower.
Description
Technical Field
The patent of the utility model relates to a vacuum pump sound-proof housing assembly belongs to car braking NVH technical field.
Background
Along with the increase of electric automobiles, the application of the vacuum pump is more and more extensive, the vacuum pump is the only vacuum source of the electric automobile and cannot be arranged at a place far away from a driver, otherwise, the vacuum pumping efficiency is influenced, but the vacuum pump is close to a cab, the noise problem of the vacuum pump can be caused, and therefore the NVH problem of the vacuum pump is more and more important.
SUMMERY OF THE UTILITY MODEL
The utility model provides a vacuum pump sound-proof housing assembly that solves above-mentioned problem, provides a simple structure, and the cost is lower to can guarantee the vacuum pump life-span.
A passenger car fluid pressure type separation and reunion footboard structure specific technical scheme as follows: the utility model discloses a vacuum pump sound-proof housing assembly comprises sound cotton of inhaling of sound-proof housing body and inboard attachement, and wherein the sound-proof housing body comprises 5 smooth connections of face, is equipped with a round hole, a slotted hole and a bolt hole on it, and then through two bolts and a bolt and vacuum pump support connection.
Further, the material of the sound insulation cover body is PA 6.
Further, the sound-absorbing cotton attached to the inner side of the soundproof cover body is a multilayer sound-absorbing cotton.
Furthermore, the multilayer sound-absorbing cotton is double-component sound-absorbing cotton of PP and PET.
The utility model discloses a vacuum pump sound-proof housing assembly can effectively reduce the noise that spreads into in the driver's cabin, can guarantee that the vacuum pump dispels the heat better, and the cost is lower.
