In the description of the present application, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.

The application relates to a target false vehicle device for testing an intelligent network-connected automobile emergency braking function, in particular to a target object for testing an intelligent driving automobile emergency braking function. In a vehicle test, the device is placed in a road, a stationary vehicle is parked in the middle of a lane in front of the simulated reality vehicle during running, the test vehicle is driven to the device at a speed of 10-80km/h or higher, the test vehicle takes emergency braking at a distance of about 5-10m in front of the device, and the vehicle is stopped before collision.

Because the test vehicle is generally a vehicle in a development stage, a state of untimely or non-braking of braking often occurs, so that the target false vehicle device is subjected to serious impact of the test vehicle, in order to ensure that the test vehicle is not damaged, the target false vehicle device needs to apply small thrust to the test vehicle as much as possible in the impact process, and needs to counteract part of impact force, and the target false vehicle device also needs to move along the collision direction after impact. The path of movement cannot be fixed due to uncertainty in the impact location, but it is necessary to protect the road facilities and the testers, and the device ensures straight running as much as possible.

The deformable elastic plate 4 arranged between the support 2 and the balloon car 1 can release impact energy in an elastic phase change mode after the balloon car 1 is impacted, so that flexible buffering is realized. Because the instantaneous impact energy between the test vehicle and the target false vehicle device is larger, when the energy released by the deformation of the elastic plate 4 is insufficient to completely transfer the impact energy, the residual impact energy can be converted into the pushing force of the elastic plate 4 to the support 2 and the support 3, so that the support 3 drives the support 2 and the balloon vehicle 1 to integrally slide, and the impact damage to the test vehicle and the target false vehicle device is avoided.

The pulley 5 arranged at the bottom of the bracket 3 can guide the target false car device to slide along a straight line in the impact direction, and can reduce the sliding distance of the target false car device through the friction force between the sliding block 6 and the ground so as to avoid collision of the target false car device to buildings at two sides of a road in the sliding process.

The backplate 22 is mainly used for bearing impact force, and after the deformation of the elastic plate 4 is released, the residual impact energy is converted into the pushing force of the balloon 1 to the elastic plate 4, so that the elastic plate 4 drives the support 3 to slide through pushing the backplate 22, and the bottom plate 21 can effectively prevent the balloon 1 from directly rubbing with the ground, thereby avoiding the occurrence of friction damage of the balloon 1.

The elastic plate 4 comprises a plurality of channels which are arranged at intervals, and the plurality of channels of elastic plates 4 are uniformly distributed between the balloon car 1 and the backboard 22.

The two brackets 3 respectively comprise a connecting rib 31, a diagonal brace 32 and a transverse brace 33 which are positioned on the same plane, so that a relatively stable pushing stress plane can be formed, and the two planes are preferably arranged in parallel, so that the brackets 3 can slide along the pushing force of the impact energy conversion in the impact direction.

The two brackets 3 are symmetrically arranged at the rear side of the backboard 22, so that a three-dimensional bearing space can be formed, and the sliding is facilitated to be reliably carried out under the action of pushing force.

The pulley 5 and the sliding block 6 are connected to the lower part of the connecting rib 31, that is, the pulley 5 and the sliding block 6 are arranged at the bottom of the target false car device, and the pulley 5 and the sliding block 6 in the embodiment take account of the sliding of the whole device to transfer the impact energy which is not completely released, control the sliding distance of the whole device, and simultaneously can play a role in controlling the sliding direction.

Specifically, the pulley 5 comprises unidirectional wheels, so that the whole device can slide under the driving force, and meanwhile, a good guiding effect is achieved.

After the balloon car 1 is impacted by a test vehicle, the balloon car 1 moves to the backboard 22 of the support 2, firstly, the impact force of the balloon car 1 is received by the variable-rigidity spring plate, and as the variable-rigidity spring plate is deformable, firstly, the spring plate deforms itself, contacts the backboard 22 after deforming to a certain extent, and the rigidity after deformation is increased again, so that the variable rigidity is formed, and different resistances are ensured to be generated under different stress conditions. Most of impact force is counteracted in the deformation process of the variable-rigidity spring plate, and the impact of the balloon car 1 on the backboard 22 is reduced, so that the whole device can be helped to move backwards for a small distance, and the safety of personnel, equipment and roadside facilities is ensured.

When the test is carried out, the target false car device for automobile test is placed on a test road, the elastic plate 4 is welded on the bottom plate 21 of the support 2, the unidirectional pulley 5 and the sliding block 6 are fixed on the connecting rib 31, the connecting rib 31 is fixed on the bottom plate 21, and the balloon 1 is placed on the bottom plate 21 and is firmly bound by a rope. After being impacted, the target false car device can receive larger impact force, after the balloon car 1 is impacted, the balloon car moves towards the elastic plate 4 at first, the elastic plate 4 deforms to offset a part of impact force, then the elastic plate 4 pushes the backboard 22 to move, and the whole impact force can be reduced because the elastic plate 4 offsets a part of impact force.

If the sliding resistance of the device on the ground is too large, the force of the device reacting to the vehicle is large, the vehicle is easy to damage, and if the sliding resistance of the device on the ground is too small, the device can be impacted to scratch a long distance, which is not beneficial to safety.
