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 reflecting in causing gas pedal to actually use, 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 of simulation 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.
Invention content
The object of the present invention is to provide a kind of test mechanisms simple in structure, convenient for test electronic accelerator pedal performance.
To achieve the above object, present invention employs following technical schemes：A kind of throttle testing machine of simulation practical operation
Structure, including table top is tested, setting mounting base and electric cylinders holder on the table top, the mounting base is for installing oil to be detected
Door pedal, fixes mobile mechanism on the electric cylinders holder；The mobile 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 holder
The shaft for including joint ball by one between electric cylinders fixed seat is connect；The preceding output end 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 done on the axis of accelerator device, and as throttle is operated
Circular motion, the point of application can move down therewith, cause the deviation of experimental data and truth；The mobile mechanism can lead to
It crosses and includes the shaft of joint ball to adjust the angle of force direction, have joint ball that can simulate the joint of 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 with gas pedal for fixed force head, 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 is used for the gravity of balanced sequence mechanism, and 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 be with real simulation driver's practical operation throttle the case where, 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 implementation mode
As shown in Figure 1, a kind of throttle test mechanism of simulation practical operation, including experiment table top 10, the table top 10

On holder bottom plate 20, gas pedal 2 to be detected is installed in the mounting base 1, moving machine is fixed on the electric cylinders holder 19
Structure；The mobile mechanism includes electric cylinders 15, connecting rod 8, pressure sensor 6 and force head 5；Servo electricity built in the electric cylinders
Machine works to control electric cylinders 15, and the tail end of the electric cylinders 15 is provided with electric cylinders connecting seat 16；It is arranged on the electric cylinders holder 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, is used for balanced sequence
The gravity of mechanism, the support device include supporting block 11, sliding rail 12, spring 13 and spring mounting seat 14, and supporting block 11 is pacified
On sliding rail 12, sliding rail 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；Sliding rail 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
Preceding output end is connect by conversion head 9 with connecting rod 8, and the other end of the connecting rod 8 connects pressure by sensor connector 7
