Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1, according to the embodiment of the utility model provides a load test frock, including test jig 1, the upper portion of test jig 1 is provided with the roller set corresponding with the wheel 2 of being tried on, the roller set is including all around self axis pivoted preceding damping roller 3 and back damping roller 4, preceding damping roller 3 and back damping roller 4 all connects magnetic powder damper 7 through chain 6.
In a specific embodiment of the present invention, the testing jig 1 is fixedly provided with a front guide plate 8, the front guide plate 8 is disposed obliquely, the upper end of the front guide plate corresponds to the roller set, and the lower end of the front guide plate extends to the bottom of the testing jig 1.
The utility model discloses a concrete embodiment, the roller set still includes a plurality of deflector rolls 5 that can wind self axis pivoted, all deflector roll 5 all is located preceding damping roller 3 and between the back damping roller 4, each fixedly connected with slider in both ends about the deflector roll 5 rotation axis, the slider is with the vertical sliding connection of test jig 1, the bottom of slider with be provided with spring 9 between the test jig 1.
In a specific embodiment of the present invention, the trial run is a balance car or an electric scooter.
In a specific embodiment of the present invention, the upper portion of the testing jig 1 is further provided with a fixing frame corresponding to the tested car body, and the fixing frame includes two clamping plates capable of sliding left and right.
For the convenience of understanding the above technical solutions of the present invention, the above technical solutions of the present invention will be described in detail through specific use modes.
Load test frock include test jig 1, preceding damping roller 3, back damping roller 4, deflector roll 5, chain 6, magnetic damper 7, preceding deflector 8 and spring 9.
The test jig 1 comprises a left fixing plate and a right fixing plate, a front guide plate 8 and a plurality of connecting rods for connecting the two fixing plates, a fixing frame is further arranged between the two fixing plates, the fixing frame comprises a left clamping plate and a right clamping plate which are used for clamping a tested automobile body, the clamping plates can slide left and right along the connecting rods, the left and right sides of the tested automobile body can be locked on the fixing connecting rods through screws, and therefore the tested automobile body can be prevented from flying out due to the deviation of the guide rollers 5 when the tested automobile moves rapidly.
