Description

Technical Field

[0001] The utility model relates to the technical field of unmanned driving, in particular to a safety protection device for an unmanned driving vehicle. Background Art

[0002] A driverless car is a type of intelligent vehicle, also known as a wheeled mobile robot. It primarily relies on an in-vehicle computer-based intelligent driverless system to achieve autonomous operation. These vehicles use onboard sensor systems to perceive the road environment, automatically plan routes, and control the vehicle to its intended destination. These sensors sense the vehicle's surroundings and, based on this information, control its steering and speed, ensuring safe and reliable road travel.

[0003] For example, Publication No. CN218112562U is titled as an unmanned driving safety protection device, which includes a vehicle head, a mounting frame detachably connected to the front side of the vehicle head, a through slot penetrating the front side wall of the mounting frame is provided on the mounting frame along the width direction of the vehicle head, and at least two buffer components are provided in the through slot. When the vehicle head is hit, the anti-collision plate collides with the object immediately and then transmits the force to the damping rod. The damping rod drives the slider to slide to partially buffer the force, thereby gaining buffer time for the normal pop-up of the airbag and protecting the safety of the people in the vehicle.

[0004] During use of the above device, since the anti-collision bar is set at a low position, if it hits a pedestrian, it will hit the pedestrian's legs. Under the action of impact force and inertia, the pedestrian will flip and hit the car hood or car windshield, which is likely to cause secondary damage and damage to the vehicle. At the same time, it is easy to injure the passengers in the car, resulting in greater damage. Therefore, we have proposed an unmanned vehicle safety protection device to solve the above problems. Utility Model Content

[0026] If the camera sensor 17 detects that a collision with a pedestrian is imminent, the inflation system 13 will be activated first to inflate the airbag 15. Under the action of the pressure of the airbag 15, the lock 14 will be opened, causing the cover 10 to flip backward and the airbag 15 to expand. The pedestrian will be hit and hit the airbag 15, which can reduce the impact force on the pedestrian to a certain extent and prevent the pedestrian from hitting his legs and rolling backward to hit the hood or windshield and suffer secondary damage.

[0027] See also Figure 1 The bottom plate 9 and the protective plate 1 are connected by a gas rod 7, and two gas rods 7 are provided and respectively installed on the outside of the bottom plate 9 and the protective plate 1.
