The connecting column 8 and the bottom of the supporting column 1 are hinged on the pedal profiling piece 3. Therefore, the folding angles between the front fork 6 and the connecting post 8, between the connecting post 8 and the stay 1, and between the stay 1 and the rear fork 7 can be changed accordingly when an impact is applied.

As shown in fig. 3, the limiting groove has two first limiting walls 9 forming an included angle with each other, and the bottoms of the connecting column 8 and the supporting column 1 are respectively tightly attached to the two first limiting walls 9, so that the rotating angles of the connecting column 8 and the supporting column 1 are limited, the connecting column 8 and the supporting column 1 can be conveniently and rapidly restored to the initial angles during repeated tests, and the consistency of the riding type soft target during appearance restoration is ensured.

As shown in fig. 4, a groove body 11 with an opening at the bottom is arranged in the connecting seat 10, second limiting walls 12 are arranged on the left side and the right side of the groove body 11, the tops of the front fork 6 and the connecting column 8 extend into the same groove body, the tops of the supporting column 1 and the rear fork 7 extend into the groove body of another connecting seat, and the second limiting walls 12 in the two connecting seats respectively limit the rotation angles of the front fork 6 and the connecting column 8 and the rotation angles of the rear fork 7 and the supporting column 1.

The tops of the front fork 6 and the connecting column 8 are respectively hinged in a connecting seat through two third damping rotating shafts; two ends of the third damping rotating shaft are locked on the connecting seat through nuts.

The tops of the strut 1 and the rear fork 7 are respectively hinged in the corresponding connecting seats 10 through two fourth damping rotating shafts; both ends of the fourth damping rotating shaft are locked on the connecting seat 10 by nuts.

Specifically, the front fork 6 includes a front auxiliary stay 13 and a front fork body 14, and the bottom of the front auxiliary stay 13 is hinged to the wheel disc center of the front wheel 4. The top of the front auxiliary strut 13 is detachably connected with the bottom of the front fork body 14, and the top of the front fork body 14 is hinged in the connecting seat 10.

In order to facilitate the detachment and more accurately simulate the deformation or folding condition of the vehicle, the detachable structure between the front auxiliary stay 13 and the front fork body 14 is: the front auxiliary strut 13 and the front fork body 14 are connected in an adsorption mode through the magnet assembly 29, the magnet assembly 29 has the torque resistance, and when a soft target object is impacted, the front wheel 4 is separated from the front fork body 14, so that damage to a main body frame caused by the impact is reduced.

The magnets attract each other, so that torsion between the two adsorbed objects can be prevented, and the reliability of connection between the two adsorbed objects is improved.

In order to achieve a reliable folding, the foot cam 3 is not fixedly connected to the front wheel 4 and the rear wheel 5, and does not interfere with the normal folding action of the front fork and the rear fork.

As shown in fig. 1, the pedal cam 3 is provided with a vertical supporting column 18, the supporting column 18 is used for keeping a soft object of the riding vehicle in a standing position, the bottom of the supporting column 18 is detachably fixed on a movable bottom plate 19, for example, the supporting column 18 can be screwed or clamped on the bottom plate 19, or can be adsorbed on the bottom plate 19 through a magnet block. The wheel is supported by another support, for example, by placing the wheel on the ground without the wheel contacting the bottom plate 19. The base plate 19 is placed on a support, such as the ground, and when the base plate 19 is moved, friction occurs between the wheels and the support to roll.

To reduce the weight of the soft target to reduce the impact force on the test vehicle at impact, all components are made of lightweight materials. In order to solve the problems of low density of light materials and insufficient reflection of radar waves of 77GHz millimeter wave radar, aluminum foils can be attached or metal coatings can be sprayed on metal parts of riding vehicles such as real bicycles, electric bicycles, motorcycles and the like.

The upper end of the front fork of the riding type soft object is also provided with a simulation bicycle handle which can be connected with the arm of the dummy.

The working principle of the soft target object is as follows:

after the riding type soft object is arranged on the bottom plate 19, the surface of the wheel is in contact with the ground. When the bottom plate 19 is dragged, the wheels can present a rolling state due to the ground friction force, so that the rolling process of the wheels when the riding type soft object moves is simulated.

As shown in fig. 7 and 8, when a riding type soft object is impacted, especially a front impact and a rear-end impact, each part of the frame impacted rotates due to the impact force, and then automatically folds at an angle to absorb the maximum impact force at the first moment of impact, reduce the impact force on a test vehicle, and also give more braking response time to a test person.
