Abstract
The utility model provides a communicating device for measurement on pneumatic pressure the surface of a car body, belonging to the measuring field on the pneumatic pressure the surface of the car body. In the utility model, a round sheet is convex and is internally provided with a plastic thin pipe with a bevel of 90 degrees; one end of the plastic thin pipe is vertically opened at the center of the round sheet; furthermore, the opening is parallel and level to the surface of the round sheet; the opening of the plastic thin pipe is a collecting opening; the opening at the other end of the plastic thin pipe is arranged at the side part of the round sheet and extends out of the side part by certain length; the opening at the other end of the plastic thin pipe is an output opening; the parts of the round sheet, contacted with the surface of the car body with the pneumatic pressure to be measured, are coated by non-drying adhesive or other adhesives. By adopting the communicating device, under the condition without damaging the surface of the car body or independently buying a special minisize pressure sensor in additional, the measurement on the pneumatic pressure of the surface of the car body can be completed only by a pressure scanning valve; and the communicating device is particularly suitable for realizing guiding the airflow pressure in the wind tunnel of the car. The communicating device has simple structure, is easy to manufacture, has low cost and is convenient for use.
Description
Technical field
The utility model belongs to the fields of measurement of body of a motor car surface Pneumatic pressure, is specifically related to the communication apparatus that body of a motor car surface Pneumatic pressure is measured.
Background technology
Automotive aerodynamics is the important content in the automobile engineering research, when being everlasting wind tunnel test or vehicle road test, gathers the pressure of bodywork surface in the automotive aerodynamics research.Traditional pressure survey mode has two kinds: a kind of is micro pressure sensor directly to be attached to the body of a motor car surface measure; Another kind is by in the bodywork surface perforate, and copper pipe is imbedded bodywork surface, connects copper pipe and pressure scanning valve by plastic straw, realizes the measurement of pressure.
First method needs a large amount of special micro pressure sensors, so capital consumption is big, and this micro pressure sensor can not also be not suitable for carrying out the measurement of small scale model surface pressure simultaneously, so function singleness in other occasion use.
Though but second method applying pressure scanning valve, the layout of pressure tap needs the damage model surface to realize, measures for automobile real vehicle surface pressing, then needs the body structure of failure test sample car, so experimentation cost is increased, the preparatory period prolongs.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that prior art exists, provide a kind of and both can not destroy the body of a motor car surface, can additionally separately not buy the special micro pressure sensor that is affixed on bodywork surface again, be used for the communication apparatus that body of a motor car surface Pneumatic pressure is measured.
The utility model is made up of thin rounded flakes 1, plastic straw 2, delivery outlet 3 and acquisition port 4, wherein thin rounded flakes 1 is convex, thin rounded flakes 1 inside is provided with the plastic straw 2 that is 90 degree knuckles, one end vertical openings of plastic straw 2 is in the center of thin rounded flakes 1, and opening part is surperficial concordant with thin rounded flakes 1, and this opening of plastic straw 2 is an acquisition port 4; The other end of plastic straw 2 is opened on the sidepiece of thin rounded flakes 1, and stretches out the sidepiece partial-length, and this opening of plastic straw 2 is a delivery outlet 3; Thin rounded flakes 1 scribbles adhesive sticker or other bindings with the body of a motor car surface contact portion of tested Pneumatic pressure; The thickness of thin rounded flakes 1 is less than 5 millimeters; The inside diameter of plastic straw 2 is the 0.8-1.5 millimeter.
The course of work of the present utility model is as follows:
Thin rounded flakes 1 fits in tested car model or real vehicle surface through adhesive sticker or other bindings, when air current flow, the pressure of collection point is entered by acquisition port 4, and be delivered on the pressure scanning valve or pressure transducer that is connected with delivery outlet 3, thereby realize measurement to the collection point Pneumatic pressure through plastic straw 2.
Good effect of the present utility model has been to overcome the drawback of traditional automobile real vehicle surface pressing measuring method, do not destroying the body of a motor car surface, under the situation of the special micro pressure sensor of extra separately purchase, adopt communication apparatus of the present utility model, be particularly suitable in automobile wind tunnel realizing guiding, realize that applying pressure scanning valve can be to the measurement of body of a motor car surface Pneumatic pressure stream pressure.The utility model is simple in structure, making is easy, with low cost, easy to use.

Wherein: 1. thin rounded flakes 2. plastic straws 3. delivery outlets 4. acquisition port
Embodiment
Thin rounded flakes 1 in the utility model is convex, its inside is provided with the plastic straw 2 that is 90 degree knuckles, one end vertical openings of plastic straw 2 is in the center of thin rounded flakes 1, and opening part and thin rounded flakes 1 is surperficial concordant, and this opening of plastic straw 2 is an acquisition port 4; The other end of plastic straw 2 is opened on the sidepiece of thin rounded flakes 1, and stretches out the sidepiece partial-length, and this opening of plastic straw 2 is a delivery outlet 3; Thin rounded flakes 1 scribbles adhesive sticker or other bindings with the body of a motor car surface contact portion of tested Pneumatic pressure; The thickness of thin rounded flakes 1 can reduce the interference of communication apparatus to Pneumatic pressure itself less than 5 millimeters; The inside diameter of plastic straw 2 is the 0.8-1.5 millimeter, and diameter too conference influences the surface pressure force measurement; The material of thin rounded flakes 1 can be used steel, aluminium or copper.
Thin rounded flakes 1 fits in tested car model or real vehicle surface through adhesive sticker or other bindings, acquisition port 4 is the inlet of collection point Pneumatic pressure, Pneumatic pressure is delivered to through plastic straw 2 on the pressure scanning valve or pressure transducer that is connected with delivery outlet 3, realizes the measurement to the collection point Pneumatic pressure.
