Fig. 1 is the structural schematic diagram one of detection device provided by the embodiment of the utility model；Fig. 2 is the utility model implementation
The structural schematic diagram two for the detection device that example provides；Fig. 3 is the partial enlarged view in Fig. 2 at A.
Please refer to Fig. 1-Fig. 3.The present embodiment provides a kind of detection devices, comprising: mounting base 10 and setting are in mounting base
Measuring device 20 on 10 has joint face in mounting base 10, attraction part is provided on joint face, attracts part for attracting automobile
Car body.
Detection device includes measuring device 20 and host, and host is electrically connected with measuring device 20；It is carried out to taxi
When detection, measuring device 20 is arranged on the car body of automobile, starts taxi later, so that taxi travels a distance,
Measuring device 20 detects the gauged distance of taxi traveling in the process, and the gauged distance of traveling is input to host later
It is interior；Staff compares the gauged distance obtained by host with by obtaining measurement distance on the meter on taxi
It is right, to determine the accuracy of meter, realize the detection to meter.
Measuring device 20 in the present embodiment can be arbitrarily be able to detect the device of running car distance, such as: measurement
Device 20 may include optical sensor, and optical sensor obtains the image on ground in a detection moment, and take in image with
Its corresponding fisrt feature point, obtains the image on ground in next detection moment later again, and takes of its face in image
Two characteristic points, the distance between two characteristic points of detection can obtain the operating range of automobile；Adjacent two detection of optical sensor
Time interval between moment is shorter, and the operating range that all adjacent two detection moments obtain is added to the mark that automobile can be obtained
Quasi- operating range.Certain measuring device 20 can also be capable of detecting when the device of the standard operating range of automobile for other.
In the present embodiment, the structure of mounting base 10 can there are many；Such as: mounting base 10 can be plate-like, corresponding to survey
Mounting base 10 is arranged on the side of car body in amount device 20, and the another side of mounting base 10 is towards car body
Joint face；Certainly, mounting base 10 can also be in other shapes, as long as guaranteeing that measuring device 20 may be mounted at mounting base 10
On, and have and the joint face towards car body in mounting base 10.
In an achievable mode, measuring device 20 is connect by shaft with mounting base 10, is filled accordingly in measurement
It sets and is provided with axis hole on 20, one end of shaft is connect with mounting base 10, and the other end of shaft is rotatably threaded through in axis hole, is made
Obtaining measuring device 20 can rotate relative to mounting base 10, to adjust the position of measuring device 20；Further, it is set in axis hole
It is equipped with rolling bearing, the outer ring of rolling bearing and the inner wall of axis hole connect, and shaft is threaded through in the inner ring of rolling bearing, and shaft is logical
It crosses rolling bearing to connect with measuring device 20, to reduce the twisting resistance of torsion measuring device 20, convenient for adjusting measuring device 20
Position.
In other implementations, measuring device 20 can also be connect with mounting base 10 by bolted connection,
Correspondingly, being provided with the first mounting hole in measuring device 20, the second mounting hole is provided in mounting base 10, installation bolt is worn
