Abstract
The utility model discloses a novel air door rubber coating prevents structure of whistling, including the air door main part, rubber limit I and rubber limit II, rubber limit I sets up in the top of air door main part, and rubber limit II sets up in the below of air door main part, and the middle part of rubber limit II is provided with a plurality of breach strakes, and the thickness direction of breach strake is parallel with the thickness direction of air door main part, the utility model discloses rational in infrastructure, convenient to use through set up the breach strake on rubber limit II, when vehicle air conditioner operation, becomes the torrent with the laminar flow originally of air, has disturbed gas flow, reduces or has eliminated the problem of whistling that produces when vehicle air conditioner operation, has improved the travelling comfort.
Description
Technical Field
The utility model relates to an automobile air conditioner technical field, concretely relates to novel air door rubber coating prevents structure of whistling.
Background
The air conditioner air door of the existing automobile air conditioner comprises an air door main body, a rubber edge I and a rubber edge II, wherein the rubber edge I is arranged above the air door main body, the rubber edge II is arranged below the air door main body, and the structure can generate a squeaking sound after the automobile air conditioner runs, so that the riding experience of a person is influenced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a rational in infrastructure, convenient to use can effectively reduce vehicle air conditioner and be the novel air door rubber coating of producing the sound of whistling at the operation and prevent the structure of whistling.
In order to achieve the above object, the technical solution of the present invention is: the utility model provides a novel air door rubber coating prevents structure of whistling, includes the air door main part, rubber limit I and rubber limit II, and rubber limit I sets up in the top of air door main part, and rubber limit II sets up in the below of air door main part, its characterized in that: and a plurality of notch edge strips are arranged on the middle part of the rubber edge II, and the thickness direction of the notch edge strips is parallel to that of the air door main body.
Furthermore, the shape of the notch edge strip is triangular, arc or polygonal, and the notch edge strip is uniformly distributed in the middle of the rubber edge II.
Furthermore, the shape of the notch edge strip is an equilateral triangle, and the height of the equilateral triangle is 1cm-3 cm.
Furthermore, the rubber edge II and the notch edge strip are of an integrally formed structure.
The utility model discloses rational in infrastructure, convenient to use through set up the breach strake on rubber limit II, when vehicle air conditioner moves, becomes the torrent with the laminar flow that the air was originally, has disturbed gas flow, reduces or has eliminated the problem of squeaking that produces when vehicle air conditioner moves, has improved the travelling comfort.
Drawings
Fig. 1 is a perspective view of the present invention;
FIG. 2 is a schematic structural view of the present invention;
fig. 3 is a side view of the present invention.
Description of the drawings: 1. air door main part, 2, rubber limit I, 3, rubber limit II, 4, the breach strake.
Detailed Description
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
The technical scheme of the utility model is described in detail by combining the attached drawings, a novel air door rubber coating anti-squeal structure comprises an air door main body 1, a rubber edge I2 and a rubber edge II 3, wherein the rubber edge I is arranged above the air door main body, the rubber edge II is arranged below the air door main body, a plurality of notch edge strips 4 are arranged in the middle of the rubber edge II, the specific notch edge strips can be arranged on the edges of the middle part, the rubber edge II can also be in an integrated structure with the notch edge strips, the thickness direction of the notch edge strips is parallel to the thickness direction of the air door main body, when an automobile air conditioner operates, laminar flow of air is changed into turbulent flow through the arranged notch edge strips, gas flow is disturbed, the squeal problem is effectively reduced, the optimal notch edge strips are triangular, arc or polygonal, the notch edge strips are uniformly distributed in the middle of the rubber edge strips, and through subjective test of ears in vehicle NVH, through the arrangement of the notch edge strips, when the height of the notch edge strips is smaller than 1 and larger than 3, the howling can be reduced, but the effect of reducing the howling is smaller, and when the shape of the notch edge strips is an equilateral triangle and the height of the equilateral triangle is 1cm-3cm, the howling can be obviously reduced or the effect of eliminating the howling can be almost achieved.
The foregoing shows and describes the general principles of the present invention, with its principal features and advantages, and further, various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
