Background technology
Test and experimental technique field in many throttle product requirements there are detection demands such as throttle test and experiments,
Common throttle test equipment is mainly using vertical pressing gas pedal, and gas pedal is in use, driver's foot
Accelerator pedal face is into the angle of one, if any producer's design driver and pedal tread into 10 degree or so of angle（This is
The design conditions of different manufacturers determine）.It is inconsistent so as to cause the experiment direction and behaviour in service of our gas pedal product,
The problem of gas pedal is caused to reflect in actually using, our experiment process does not have Validity Test to go out.In this background, city
Wish to release a kind of throttle testing machine mechanism for simulating practical operation on field, which can be stepped on the gas with real simulation driver's foot
Pedal operation, the true performance characteristics for reflecting product.
The content of the invention
The object of the present invention is to provide a kind of test mechanisms simple in structure, convenient for testing electronic accelerator pedal performance.
To achieve the above object, present invention employs following technical schemes：A kind of throttle testing machine for simulating practical operation
Structure including testing table top, sets mounting base and electric cylinders stent, the mounting base is used to install oil to be detected on the table top
Door pedal, fixes moving mechanism on the electric cylinders stent；The moving mechanism include electric cylinders, connecting rod, pressure sensor and
Exert a force head；The tail end of the electric cylinders is provided with electric cylinders connecting seat；Electric cylinders fixed seat, electric cylinders connecting seat are set on the electric cylinders stent
The shaft for including joint ball by one between electric cylinders fixed seat is connected；The preceding output terminal of the electric cylinders passes through conversion head and company
Extension bar connects, and the other end of the connecting rod connects pressure sensor by sensor connector；Distinguish at pressure sensor both ends
Installation force head and sensor connector；Force head directly acts on gas pedal to be detected.
In traditional simulated operation, the point of application is on the axis of accelerator device, and as throttle is operated what is done
Circular motion, the point of application can move down therewith, cause the deviation of experimental data and truth；The moving mechanism can lead to
It crosses and includes the shaft of joint ball to adjust the angle of force direction, there is the joint that joint ball can simulate people leg inside shaft
Movement so that detection is more life-like, and the size of angle can be determined according to the difference of producer, automobile model, and effect is more
It is good.
Further, point of application fixture, the point of application fixture and force head shapes are also equipped in the gas pedal
Agree with, position when being contacted for fixed force head with gas pedal, so set, finding real driving feelings in gas pedal
After the point of application in condition, in order to which real simulation people foot steps down in the constant situation of the point of application on throttle, installed in gas pedal
Point of application fixture, to limit the position of force head.
Further, be additionally provided with support device on the experiment table top, the support device be located at electric cylinders front end just under
Side, for the gravity of balanced sequence mechanism, the support device includes supporting block and spring, and such setting can be with real simulation people
The articulated way of leg, and play the role of balancing gravity.
The beneficial effects of the present invention are：It is simple in structure, can with the situation of real simulation driver's practical operation throttle, and
And the distance between entire mechanism arrangement all with truth 1:1 corresponds to, and substantially increases the reliability of experimental data, improves
The security performance and user experience of automobile.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
As shown in Figure 1, a kind of throttle test mechanism for simulating practical operation, including testing table top 10, the table top 10
Upper setting mounting base 1 and electric cylinders stent 19, mounting base 1 are fixedly mounted in mounting base fixed plate 3, and electric cylinders stent 19 is fixedly mounted
On stent bottom plate 20, gas pedal 2 to be detected in the mounting base 1 is installed, moving machine is fixed on the electric cylinders stent 19
Structure；The moving mechanism includes electric cylinders 15, connecting rod 8, pressure sensor 6 and force first 5；Servo electricity built in the electric cylinders
Machine, electric cylinders 15 to be controlled to work, the tail end of the electric cylinders 15 is provided with electric cylinders connecting seat 16；It is set on the electric cylinders stent 19
Electric cylinders fixed seat 17 is connected between electric cylinders connecting seat 16 and electric cylinders fixed seat 17 by a shaft for including joint ball 18；Institute
It states and is additionally provided with support device on experiment table top 10, the support device is located at the underface of 15 front end of electric cylinders, for balanced sequence
The gravity of mechanism, the support device include supporting block 11, slide 12, spring 13 and spring mounting seat 14, and supporting block 11 is pacified
On slide 12, slide 12 is vertically arranged, and spring 13 is mounted on spring mounting seat 14, on, the bottom surface of supporting block 11 and spring
13 tops are fixedly connected and press on spring 13；Slide 12 limits supporting block 11 and can only down be transported in the vertical direction along it
It is dynamic, thus have the function that the side-to-side movement of supporting block 11 planar is avoided to cause experimental data error；The electric cylinders 15
