Abstract
The utility model discloses a fixing device of an interior noise testing sensor, which comprises a seat headrest (1) and sensors (4). Bandages (2) made of cotton material are arranged on the periphery of the outer portion of the seat headrest (1); two circular holes (3) are respectively arranged on the bandages (2) on two lateral surfaces of the seat headrest (1); and the sensors (4) are placed inside the circular holes (3). By adopting the technical scheme, the sensors can be directly tightly attached to the lateral surfaces of the seat headrest and simulate human ear positions in real manner; tested data can more truly reflect real feeling of human ears; the bandages made of cotton materials can avoid damage to a data wire and the sensors; and the sensors are placed inside the bandages, thereby the fixing device is convenient in installation, labor-saving, time-saving, and reliable in fixing.
Description
Technical field
The utility model relates to a kind of stationary installation of internal car noise testing sensor.
Background technology
As everyone knows, the internal car noise test generally is the noise figure at test driver and ear place, the passenger left and right sides, be about to sensor be fixed on chair headrest about or an independent side come image data, at present, the fixedly great majority of sensor are to use metal support that sensor is fixed on the headrest side, part also uses adhesive tape that sensor is sticked on the chair headrest, and there is following shortcoming in these two kinds of forms:
1, metal support extends through outward far, and the range deviation between people's ear is excessive, causes the problem of data distortion; Adhesive tape forms a circle acoustic emission band near sensor, cause the data acquisition distortion; The destruction that the long-time use of metal support very easily causes chair headrest;
2, metal support and adhesive tape damage the headrest surfacing easily.
The utility model content
Problem to be solved in the utility model provides a kind of stationary installation of internal car noise testing sensor, its objective is that to make data acquisition truer.
To achieve these goals, the technical scheme taked of the utility model is:
The stationary installation of this internal car noise testing sensor provided by the utility model, comprise chair headrest and sensor, on described chair headrest outer periphery, be provided with the bandage of cotton material, two circular holes are arranged respectively on the bandage of described chair headrest two sides, and described sensor is placed in the described circular hole.
The distance of described two circular holes is 60～70 millimeters, and its diameter is 10～15 millimeters.
Described bandage is of a size of: wide is 60 millimeters, and thickness is 4 millimeters, and the girth before not stretching is 500 millimeters.
Adopt technique scheme, sensor directly is close to the side of chair headrest, real simulation people ear position, the actual impression of actual response people ear of test data, the bandage of cotton material can not cause damage to data line and sensor, sensor is placed in the bandage, and is easy for installation, time saving and energy saving and fixing reliable.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this instructions and the mark among the figure are made brief description:
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure:
1, chair headrest, 2, bandage, 3, circular hole, 4, sensor.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and principle of work, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1, this is a kind of stationary installation of internal car noise testing sensor, comprises chair headrest 1 and sensor 4.
In order to solve the problem that exists at the described present known technology of this instructions background technology part and to overcome its defective, realize that image data is more true.The technical scheme that the utility model is taked is:
As shown in Figure 1, this internal car noise testing sensor stationary installation provided by the utility model, on described chair headrest 1 outer periphery, be provided with the bandage 2 of cotton material, two circular holes 3 are arranged respectively on the bandage 2 of described chair headrest 1 two sides, and described sensor 4 is placed in the described circular hole 3.
Adopt technique scheme, use the bandage of cotton material, absorption to sound is similar with described chair headrest, can not cause interference to sound, more truly simulated automotive passenger room sound field, solve adhesive tape and near sensor, formed a circle zone of reflections, cause the problem of data distortion, also solved support simultaneously and extended through outward far, excessive with people's ear physical location deviation, cause the problem of data distortion, sensor stand also is resolved to the problem that chair headrest very easily destroys in addition.
The distance of described two circular holes 3 is 60～70 millimeters, and its diameter is 10～15 millimeters.
Described bandage 2 is of a size of: wide is 60 millimeters, and thickness is 4 millimeters, and the girth before not stretching is 500 millimeters.
Adopt technique scheme, directly the bandage 2 with cotton is enclosed within on the chair headrest 1, cutting off two diameters in described bandage 2 centre positions at a distance of 60～70 millimeters is 10～15 millimeters circular hole 3, directly sensor 4 is inserted in two circular holes 3, suitably adjust the position of described bandage 2 and sensor 4, guarantee that sensor 4 heads exceed 10～20 millimeters of chair headrests, can guarantee the authenticity of test data.
The cotton bandage also has following advantage in addition:
1, the cotton bandage has elasticity, and stretch can the intact applying with the headrest of arbitrary shape;
2, the cotton bandage comfortable, be easy to clean, easy for installation, time saving and energy saving and fixing reliable, can not cause damage to data line and sensor.
The technical scheme that the utility model adopted compared with prior art, has tangible difference, possessed outstanding substantial characteristics, and obtained marked improvement technically, be worth in industrial promotion and application, so, the utlity model has novelty, creativeness and practicality.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
