The specific implementation manner of this embodiment is:
before testing the motion parameters of the automobile, firstly, the optical ranging and timing box 1 and the speed change induction box 2 are installed on the tested automobile, a tester can install the equipment on an engine cover or a ceiling of the automobile according to actual requirements, when the optical ranging and timing box 1 is installed, an operator places the negative pressure suction cups 144 below the telescopic adjustable supporting legs 13 on the automobile, adjusts the orientation of the optical ranging and timing box 1 to enable the optical range finder 11 to face the advancing direction of the automobile, starts the negative pressure pumps 141, the negative pressure pumps 141 drive the gas in the negative pressure pipes 142 to flow, so that the air pressure between the negative pressure suction cups 144 and the automobile is reduced, the negative pressure suction cups 144 and the automobile are tightly attached, then, the optical ranging and timing box 1 is horizontally adjusted, and the tester telescopically adjusts the telescopic adjustable supporting legs 13, and fix each telescopic adjustable landing leg 13 through the elastic shifting piece 131, in this process, the negative sucker 144 keeps the invariable state, therefore, the included angle between the optical ranging timing box 1 and the telescopic adjustable landing leg 13 will change, the telescopic adjustable landing leg 13 rotationally connected with the lower wall of the optical ranging timing box 1 and the optical ranging timing box 1 slightly rotate, so as to match the deformation generated in the horizontal adjustment process of the equipment, prevent the equipment from being damaged or separated, after the installation of the optical ranging timing box 1 and the variable speed induction box 2, the tester fixedly installs the reflecting device 4 right in front of the test runway, and make the reflecting prism 42 face the test runway, in order to use and test conveniently, the tester can carry the control panel 3 to the vehicle.
In the initial state, the speed-changing slider 212 is stably stationary in the middle of the speed-changing sliding square tube 211 under the elastic force of the return spring 2111, the speed-changing dial rod 2112 is in the vertical state, the toggle return spring 2114 is in the loose state in the initial state, the resistance-reducing wheel 2123 close to the distance-measuring pressing electric sheet 2117 is positioned between the distance-measuring pressing electric sheets 2117, when the test is started, the operator opens the control panel 3, the driver starts the test vehicle, when the vehicle starts to move and accelerates, the optical distance-measuring timing box 1 follows the acceleration, the speed-changing induction box 2 drives the speed-changing sliding square tube 211 to follow the acceleration, the speed-changing slider 212 slides relative to the speed-changing sliding square tube 211 due to the inertia effect, the speed-changing slider 212 slides relative to the opposite direction of the test vehicle along the guide rail 2116, after the relative sliding, the upper wall of the speed-changing slider 212 contacts with the speed-changing dial rod 2112 and starts to dial rod 2112, the resistance reducing wheel 2123 between the distance measuring pressing electric sheets 2117 crosses the distance measuring pressing electric sheet 2117 behind the vehicle in the driving direction, after the distance measuring pressing electric sheet 2117 is pressed once, the optical distance measuring instrument 11 emits a distance measuring light to the reflecting prism 42 once to realize starting distance measurement, the distance between the vehicle and the reflecting prism 42 when the vehicle is started is obtained, the speed change slider 212 enables the speed change poking rod 2112 to rotate, when the upper wall of the speed change slider 212 is in sliding contact with the lower end of the speed change poking rod 2112, the rotating angle of the speed change poking rod 2112 reaches the maximum value, the poking block 2113 presses the timing press switch 2115 to enable the timer 12 to start timing, when the test vehicle reaches the test speed, a driver operates the vehicle to start to keep constant speed motion, when the speed change slider 212 starts to run at the constant speed, the resistance reducing wheel 2123 presses the distance measuring pressing electric sheet 2117 again, the optical distance measuring instrument 11 emits distance measuring light once again to obtain the distance between the vehicle and the reflecting prism 42 when the vehicle reaches the test speed, the difference between the two distances is the acceleration distance of the test vehicle, when the speed change slider 212 recovers to the initial state, the speed change poke rod 2112 also recovers to the initial state, the poke block 2113 does not press the timing press switch 2115 any more, the timer 12 stops timing to obtain the acceleration time of the vehicle, and the speed change induction box 2 is of a symmetrically arranged structure, therefore, the timing of the deceleration process and the acceleration process is the same as the distance measuring principle, the only different positions are the speed change poke rod 2112 and the distance measuring press electric sheet 2117 which are touched by the speed change slider 212 and are in front of the vehicle motion direction, and therefore, the deceleration and distance measuring timing processes are not repeated.
During the acceleration of the vehicle, there are often acceleration gaps and jerk phenomena caused by gear shifting, etc., that is, there is a possibility of sudden uniform speed or deceleration during the acceleration, for such phenomena, the present embodiment provides multiple sets of damping rods 2121 and damping balls 2122 inside the speed-changing slider 212 to cooperate with each other, so that when the vehicle suddenly stops accelerating or has jerk, the damping rods 2121 and damping balls 2122 provide damping effect for the speed-changing slider 212 to prevent the speed-changing slider 212 from suddenly moving backward relative to the speed-changing sliding square tube 211, and during this process, the lower end of the speed-changing dial rod 2112 and the upper wall of the speed-changing slider 212 are in sliding contact, that is, when the speed-changing slider 212 and the speed-changing sliding square tube 211 slightly slide relatively, the lower end of the speed-changing dial rod 2112 and the upper wall of the speed-changing slider 212 are still in sliding contact, and the continuous pressing of the timing press switch 2115 and the continuous operation of the timer 12 by the dial 2113 are not affected, and during this process, the deceleration wheel 2123 may be pressed multiple times with the distance-measuring press plate 2117, therefore, a test result may be generated, but not affect the final test data to be transmitted to the wireless transmitter panel 31 for recording by the wireless control panel 15.
