[0042] The skin appearance of a real electric bicycle is simulated by a soft covering, which can meet the requirements of near-infrared reflection characteristics, 77GHz radar reflection, RCS characteristics, etc., eliminate hard impact points, and effectively reduce the damage to the test vehicle and soft targets caused by the impact. The body support rod 21 and the load-bearing rod 22 are wrapped with metal coating and soft wrapping to simulate the radar reflection properties of a real electric vehicle.

[0043] In addition, the two wheels of the electric bicycle soft target can rotate by relying on the friction from the ground during the test, simulating the riding state of an electric bicycle on a real road. This allows the camera sensor equipped with the test vehicle to capture a more realistic electric bicycle driving on the road.

[0044] During the test, when the soft target of the electric bicycle is hit, the impact force is greater than the magnetic force of the strong magnet at the connection, and the soft target will automatically separate to reduce the impact force, thereby protecting the test vehicle and the soft target itself, that is, the first connecting seat 19 is separated from the matching connecting seat 27, and the second connecting seat 3 is separated from the connecting support plate 26, so that the vehicle body can be separated to release the impact force, and then combined with the soft cover to absorb and eliminate it to a certain extent, thereby reducing the damage caused by the impact. When assembling the first connecting seat 19, the rear lateral support rod 18 and the first strong magnet 198, the rear lateral support rod 18 and the first strong magnet 198 are assembled. After 198 is plugged in, rotating the threaded carrier rod 1952 can drive the threaded collar 196 to move toward the first connecting seat 19 under the action of the thread, and then the plug-in locking rod 1971 will be pushed to move and plug into the plug-in connecting hole 182 under the action of the movable connecting rod 1961, so as to realize the fixed connection between the rear transverse support rod 18 and the first connecting seat 19, and at the same time, the movable connecting frame 197 will also drive the movable locking plate 1973 to move and plug it into the matching ring groove 1991 to realize the fixation of the first strong magnet 198, and then complete the synchronous fixation of the transverse support rod 18 and multiple first strong magnets 198. When assembling the second connecting seat 3, the front oblique support rod 4 and the fourth strong magnet 7, after the front oblique support rod 4 and the fourth strong magnet 7 are plugged in, the two interlocking strips 8 are pushed toward the second connecting seat 3 at the same time, so that the first locking plug rod 81 is plugged into the installation matching hole 42 to achieve the fixation of the front oblique support rod 4, and at the same time, the second locking plug rod 85 is plugged into the fixed connecting hole 72 to achieve the fixed installation of the fourth strong magnet 7. The operation is simple, convenient and fast. In addition, when the two are approaching, the inclined platform 91 contacts the hole wall of the matching connecting hole 87. As the two move, the inclined surface 91 contacts the hole wall of the matching connecting hole 87. Under the action, the inclined surface platform 91 will be pushed downward, so that the inclined surface platform 91 can smoothly pass through the matching connecting hole 87, and then reset under the action of the second spring 93, so that the inclined surface platform 91 is stuck on the first matching plate 86, so that the two interlocking strips 8 are fixed, and the interlocking strips 8 are in contact with the second connecting seat 3 at this time.
