The invention discloses a pedestrian head collision protection control system and method based on a rotatable wiper shaft. Pre-judging the head drop point of the pedestrian according to the motion trail of the pedestrian around the vehicle driving environment; when the head falling point is located in the dangerous area of the windscreen wiper shaft, the windscreen wiper shaft is rotated by a set angle to a target point; the target point is a position which is obtained after arrangement checking of the windscreen wiper shaft in the vehicle design stage and meets the target value of the energy absorption space. In an unavoidable pedestrian-vehicle accident, whether the windscreen wiper shaft is rotated to increase the energy absorption space or not is determined by judging the head drop point of a pedestrian; in combination with an active safety technology, collision is pre-judged and braking avoidance is performed, and head drop point protection is pre-judged when avoidance cannot be performed; the high requirements of pedestrian head protection on windscreen wiper arrangement and windscreen wiper shaft fracture characteristics are effectively met.

This utility model discloses a compressible engine hood buffer block and a car with pedestrian protection in mind, relating to the field of automotive safety design. It includes: a cylindrical housing comprising an upper housing and a lower housing connected to each other, with a connecting hole at the top of the upper housing; a spring, one end of which is fixed inside the lower housing and positioned along the axial direction of the housing; a buffer block body, the middle of which is disposed through the connecting hole, with one end of the buffer block body outside the housing for connection to the engine hood, and the other end of the buffer block body inside the housing engaging with the inner wall of the upper housing; and a support block disposed inside the housing, with both ends connected to the spring and the buffer block body, respectively. When the engine hood with the buffer block installed is normally closed, after a pedestrian collision, the buffer block body is compressed and retracted into the housing after being subjected to the impact force, causing the engine hood to shift downwards a certain distance, creating a larger energy absorption space for head impacts and reducing head injury.

The present invention is a wearable concussion detection and monitoring system that captures and analyzes head impact data in real time. It integrates an accelerometer, a gyroscope, and a microcontroller with Bluetooth Low Energy (BLE) for wireless communication. When an impact exceeds a threshold, the system records linear and rotational acceleration, applies sensor fusion algorithms (e.g., Madgwick filter) to remove gravitational noise, and timestamps the event. Data is stored onboard and transmitted to a mobile application and cloud platform for further analysis. Machine learning models assess concussion risk, providing real-time alerts and long-term impact tracking for athletes, trainers, and medical professionals. The system enhances concussion assessment and injury prevention across sports, military, and other high-impact activities, offering an objective, data-driven approach to head injury monitoring.

The present invention belongs to the field of automobiles, and discloses a method, device, equipment and storage medium for prolonging the head impact time. The method includes: when the head impact time of a target vehicle does not meet a preset impact time threshold, obtaining the target head impact time and the current lip length corresponding to the target vehicle; determining a target lip length according to the target head impact time and the current lip length; and extending the lip length of the target vehicle based on the target lip length so as to prolong the head impact time of the target vehicle when colliding with a pedestrian. Since the present invention prolongs the head impact time of the target vehicle when colliding with a pedestrian by extending the lip length of the target vehicle. Compared with the existing method of reducing the target head impact time by reducing the deployment time of the active hood system, the above method of the present invention can avoid plastic deformation in the front hood hinge area of the vehicle caused by reducing the deployment time of the active hood system.
