[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-2 The utility model provides an embodiment: a cantilever road target carrying platform, including a mobile platform 1, a cantilever device base 2 is provided on the top surface of the mobile platform 1, a lifting device 3 is provided on the top surface of the cantilever device base 2, a telescopic arm 4 is provided on the top side of the lifting device 3, a hanging device 5 is provided on the bottom end of one side of the telescopic arm 4, and a soft target 6 is hung on the bottom end of the hanging device 5.

[0029] The hanging device 5 includes a fixed column 501 and a connecting column 502. The fixed column 501 is connected to the telescopic arm 4. The connecting column 502 is located at the top of the soft target object 6. A groove 505 is provided on the surface of the connecting column 502. A limiting column 503 is provided in the groove 505. The limiting column 503 and the surface of the groove 505 are both provided with internal threads 504. The bottom end of the fixed column 501 is provided with a hollow column 506 that is compatible with the limiting column 503. The inner and outer sides of the hollow column 506 are provided with external threads 507.

[0030] A ratchet shaft is provided inside the suspension arm device base 2 to control the rotation range and direction of the lifting device 3 .

[0031] The lifting device 3 is an electric telescopic rod connected to an external controller. The external controller can control the extension and contraction of the lifting device 3, thereby raising and lowering the height of the soft target 6, so that the soft target 6 can be accurately hit during the impact experiment.

[0032] The telescopic arm 4 is an electric telescopic rod connected to an external controller. The controller can control the extension and retraction of the telescopic arm 4 to facilitate the adjustment of the soft target 6 and the mobile platform 1 to ensure that the soft target 6 can be accurately hit during the impact test.

[0033] The hooking device 5 can replace the soft target 6, which here is a car, a motorcycle (including a dummy), an electric vehicle (including a dummy), a bicycle (including a dummy), or a pedestrian (children and adults). The soft target 6 can be replaced through the hooking device 5, which is a common locking buckle that can fix the soft target 6.

[0034] The mobile platform 1 is a small vehicle controlled by an external controller. The movement of the mobile platform 1 can be controlled by the external controller. The mobile platform 1 is used to drive the movement of the soft target 6.

[0035] Working principle: When the soft target 6 is spliced ​​with the device, first align the 503 limit column with the 506 hollow column, and then rotate the 502 connecting column so that the internal thread 504 is threadedly connected with the external thread 507, so that the connecting column 502 and the fixed column 501 are subsequently connected. An inflatable skeleton is used, which is inflated when used. The soft target 6 has different styles, including cars, motorcycles (including dummies), electric vehicles (including dummies), bicycles (including dummies), and pedestrians (children and adults), which are selected according to different tests; during the test, the mobile platform 1 and the soft target 6 travel side by side on two lanes according to the set program, and are connected by the telescopic arm 4. The test vehicle and the soft target 6 are in the same lane and approach quickly from the rear. If the test vehicle collides with the soft target 6, the soft target 6 can be rotated through the ratchet shaft 7. The internal ratchet shaft 7 can control the rotation range and direction of the cantilever device to prevent the soft target 6 from excessive rotation when hit, affecting the test safety.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
