Embodiment Construction

[0024] figure 1 It is a structural schematic diagram of a vehicle rollover prevention device 100 according to an embodiment of the present invention. The anti-rollover device 100 for a vehicle can be installed on a test vehicle in a side impact test of a deformable mobile barrier, so as to prevent the vehicle from rolling over and ensure the accuracy of test data. Such as figure 1 As shown, the vehicle anti-rollover device 100 may generally include a support assembly and a buffer part 200, the support assembly is used for installing the vehicle anti-rollover device on the vehicle. In the side impact test of the deformable mobile barrier, the side close to the driver is the impact side of the test vehicle. The buffer part 200 is movably connected with the support assembly, and is fixed on the outside of the collision side of the vehicle through the support assembly during the test, and is fixed at the bottom edge of the side frame of the test vehicle, at least able to cover t...

Abstract

The invention provides an anti-rollover device for a vehicle. The device is installed on a test vehicle during the side impact test based on a deformable moving wall barrier, wherein the test vehicleis prevented from from turning over, and the accuracy of test data is guaranteed. The anti-rollover device for the vehicle comprises a supporting assembly used for installing the anti-rollover deviceonto a vehicle; and a buffer part movably connected with the supporting assembly, fixed onto the outside of an impact side surface through the supporting assembly during test, correspondingly locatedat the lower bottom edge of the side frame of the vehicle which at least covers the point R of a vehicle front-row seat, and used for buffering the impact of the moving wall barrier to the impact sidesurface of the vehicle. In this way, the vehicle is prevented from from turning over. One side of the buffer part, facing the moving wall barrier, serves as the main impact body of the buffer part. The main impact body is composed of a metal plate-shaped object. The device provided by the invention can be used for buffering the collision impact of the moving wall barrier on the test vehicle and the test vehicle is prevented from from turning over. The damage of test equipment is reduced, and the accuracy and the continuity of test data are guaranteed.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a vehicle rollover prevention device, which is used in a side collision test of a deformable mobile barrier to prevent a test vehicle from rolling over. Background technique [0002] The side impact test of deformable mobile barrier is an important type of vehicle crash test. The general rules are: install a deformable energy-absorbing barrier at the front end of the mobile trolley, impact the driver’s side of the test vehicle with the mobile barrier, drive the barrier perpendicular to the test vehicle, and align the centerline of the mobile barrier with the R point of the test vehicle (The vehicle seat reference point is the final position of the seat during normal driving or riding), and the crash test speed must not be lower than 50km / h. The distance between the longitudinal median vertical plane of the mobile barrier and the transverse vertical plane passing through the R point...
