The technical field is as follows:

the invention belongs to the technical field of displacement sensor measurement, and relates to an auxiliary measuring device for displacement measurement in a whole vehicle test.

Background art:

in the product development process, the whole vehicle test work plays a crucial role, is an important means for evaluating the reliability of the vehicle, is an important measure for ensuring that the vehicle reaches the design expected reliability level, and is one of important links for researching and improving the reliability of the vehicle. The actual running conditions of the automobile are complex and changeable, relative motion can be generated between parts on the automobile, and for structures such as an engine suspension structure, the size of the motion amplitude can greatly influence the service life of the whole structure. At present, in the test work of the whole vehicle, the displacement load of a key part is collected and analyzed, so that the use requirement of the whole vehicle is met, and the reliability of the corresponding part is necessarily improved.

In the whole vehicle test work, the displacement change between the parts is often measured by using the stay wire type displacement sensor, so that data support is provided for verifying the design scheme or solving the test fault. The existing method is to directly connect the stay wire of the stay wire displacement sensor with a fixing device. However, the range of the stay wire displacement sensor is limited sometimes, and the selection of the measuring point is not arbitrary, so that in some parts with limited space, if a common stay wire displacement sensor installation method is adopted, the stay wire displacement sensor may interfere with vehicle parts, so that the test cannot be carried out smoothly, and the test result is influenced.

The utility model has the following contents:

the utility model provides an auxiliary measuring device for stay wire displacement sensor, aim at solves: the device is limited by the measuring range of the stay wire displacement sensor, and in the positions with a plurality of parts which are narrow and distributed in space, the interference between the sensor and the parts often occurs when the stay wire displacement sensor is installed, so that great inconvenience is generated for installing the sensor, the test efficiency is influenced, and sometimes even the measurement cannot be smoothly carried out.

An auxiliary measuring device for a pull-wire displacement sensor, comprising: the sensor comprises a fastening screw 1, an extension line 2, a fixed support 3, an adhesive layer 4, a sensor base 5 and a stay wire displacement sensor 6;

the extension line 2 is a closed inelastic coil and is fixed on the fixed support 3 through a fastening screw 1;

the fixed support 3 is connected with the measuring plane through an adhesive layer 4;

the stay wire displacement sensor 6 is fixed on the sensor base 5, and the stay wire of the stay wire displacement sensor 6 is connected with the extension line 2 and is kept in a straightening state.

Further, the length of the extension line 2 can be selected, so that the measuring range of the stay wire displacement sensor 6 is not influenced.

Furthermore, the height of the fixing support 3 can be selected, the distance between the position of the fastening screw 1 and the upper surface of the fixing support 3 is kept unchanged, and the wire pulling directions of the extension wire 2 and the wire pulling displacement sensor 6 are ensured to be consistent with the displacement direction to be measured.

Further, the height of the fixing support 3 is unchanged, the base with the selectable height is fixedly connected with the fixing support through viscose, and the wire pulling directions of the extension wire 2 and the wire pulling displacement sensor 6 are consistent with the displacement direction to be measured.

The utility model has the advantages that: the utility model provides an auxiliary measuring device for stay wire displacement sensor to combine stay wire displacement sensor, the displacement of the horizontal direction relative motion between two parallel surfaces of measurable quantity, and the flexible mounted position of selecting of extension line on the auxiliary measuring device of accessible, avoid forming the motion with vehicle spare part and interfere, and do not influence the measuring range of stay wire displacement sensor, make relevant personnel can more conveniently test. Meanwhile, the mounting positions under different conditions are adapted through the components with different specifications, so that the test accuracy is improved, and test data with ideal effects are obtained.

Detailed description of the preferred embodiments

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the technical solutions and advantages of the present invention are further described, and the following detailed description is made with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention is described in further detail below with reference to the accompanying drawings:

an auxiliary measuring device for a stay wire displacement sensor as shown in fig. 1 comprises a fastening screw 1, an extension wire 2, a fixing bracket 3 and an adhesive layer 4. The fastening screw 1 is in threaded connection with the fixing support 3, and one end of the extension line 2 is screwed and fixed on the fixing support 3; in order to ensure firm connection, after the extension line 2 is fixed on the fixing support 3 by the fastening screw 1, the fastening screw 1 is covered by AB glue, so that the strengthening effect is achieved. The extension line 2 is a closed inelastic coil. The adhesive layer 4 connects the fixing support 3 with the measuring plane by means of an AB glue.
