Description of the Drawings

[0024] Figure 1 It is a schematic diagram of the management system of the present invention. Detailed Embodiment

[0025] In order to better understand the purpose, structure and function of the present invention, the present invention will be further described in detail below with reference to the drawings.

[0026] Such as Figure 1As shown in the figure, the present invention provides an intelligent cockpit safety management system, which includes a backup battery pack, a main control unit arranged on the vehicle body, and a collision-water ingress signal acquisition unit, a water ingress self-rescue unit, a collision self-rescue unit, a biological monitoring unit, and an alarm unit that are electrically connected and communicatively connected to the main control unit respectively, and are used for collecting whether the vehicle has fallen into water or collided, whether there are children or pets left in the vehicle with power off, locking the doors, closing the windows, controlling the windows to drop to a set height for ventilation in the vehicle, controlling the vehicle that has fallen into water to start the water ingress self-rescue function, controlling the vehicle that is about to collide or has collided to start the collision self-rescue function, and using the alarm unit to alarm in time after the vehicle has fallen into water or collided.

[0027] Among them, the backup battery pack is used to provide auxiliary power for the vehicle body after the main battery pack of the vehicle body is powered off. In order to prevent the backup battery from being powered off due to water ingress, the backup battery in this embodiment needs to be sealed and the protection level reaches IP67 / IP68. The collision-water ingress signal acquisition unit is used to collect information about the vehicle falling into water, the vehicle speed and distance of oncoming vehicles in the front and rear directions of the vehicle, and information about the collision position of the vehicle, and send the signals to the main control unit. The biological monitoring unit is used to collect biological information in the vehicle and send the signals to the main control unit. The main control unit calculates and identifies the signals sent by the collision-water ingress signal acquisition unit and the biological monitoring unit, and controls the corresponding units to act. Among them, the water ingress self-rescue unit is used to control the door to unlock, the window to drop, and control the rescue airbag to inflate to assist the driver and passengers to escape after the vehicle has fallen into water; the collision self-rescue unit is used to pre-tighten the seat belt and adjust the seat state when the vehicle is about to collide or has collided; the alarm unit is used to call the unified emergency call 112 using the emergency call service.

[0028] Specifically, the collision-water ingress signal acquisition unit in this embodiment includes a plurality of water immersion sensors and radars. The plurality of water immersion sensors are redundantly arranged at the bottom, around the sides, inside the vehicle and on the roof of the vehicle body respectively. The plurality of radars are redundantly and dispersedly arranged at the front and rear ends of the vehicle body. Among them, the water immersion sensor at the bottom of the vehicle body corresponds to the wading warning of the main control unit, the water immersion sensor arranged inside the vehicle is located on the cockpit floor and corresponds to the warning of the carriage water ingress of the main control unit, and the water immersion sensor arranged on the roof of the vehicle is located on the cockpit roof and corresponds to the warning of the vehicle being completely submerged of the main control unit.

[0029] On the basis of the water immersion sensors, the collision-water ingress signal acquisition unit further includes a plurality of pressure sensors arranged on the roof of the vehicle. The pressure sensors are communicatively connected to the main control unit. When the pressure sensors and the water immersion sensors arranged on the roof of the vehicle send signals into the vehicle body together, it means that the vehicle is completely submerged.

[0030] Furthermore, the self-rescue unit for falling into water in this embodiment includes a door and window unlocking module and a life-saving airbag inflation and release module. The door and window unlocking module is electrically connected to the main control unit. When the vehicle falls into water or collides, the main control unit can control the action of the door and window unlocking module to drive the windows to fall and open completely.

[0031] The life-saving airbag inflation and release module is arranged in the center console, including a life-saving airbag and an airbag control module. The airbag control module is arranged in the main console and is detachably fixedly connected to the life-saving airbag. The main control unit is electrically connected to the airbag control module. The main control unit controls the ignition of the airbag control module and the rapid inflation and deployment of the life-saving airbag according to the received water-falling signal sent by the collision-falling-into-water signal acquisition unit. After the life-saving airbag is deployed, the driver and passengers can remove and seal the life-saving airbag, escape from the car holding the life-saving airbag, and float to the water surface and remain in a floating state under the buoyancy of the life-saving airbag. The life-saving airbag can be a simple airbag, or a shape that can be worn on the hand or on the body, as long as it can provide sufficient buoyancy for the driver and passengers, and there is no specific limitation in this embodiment.

[0032] In addition, the self-rescue unit for falling into water also includes an airbag control module and an airbag on the vehicle body. The airbag control module is electrically connected to the main control module. The main control unit controls the ignition of the airbag control module and the rapid inflation and opening of the airbag according to the signal sent by the water immersion sensor installed on the roof, thereby increasing the buoyancy of the vehicle body and helping the vehicle to stop sinking.

[0033] Furthermore, the collision self-rescue unit includes a seat belt pre-tensioning motor and a seat adjustment module. The seat belt pre-tensioning motor is arranged in the B-pillar of the vehicle body and is connected to the seat belt retractor. When the main control unit determines that the vehicle is about to be hit according to the signal detected by the radar, the seat belt pre-tensioning motor is controlled to start and drive the seat belt retractor to tighten, thereby pre-tightening the seat belt and reducing the risk of serious collision between the driver and the center console due to a huge impact on the vehicle.

[0034] The seat adjustment module is arranged under the seat and is electrically connected to the motor for adjusting the front and rear position movement of the seat and the backrest posture. The main control unit is electrically connected to the seat adjustment module. The main control unit controls the seat adjustment module according to the warning signal sent by the received radar and the signal that a collision has occurred, and drives the motor for adjusting the front and rear position movement of the seat and the backrest posture to operate at the maximum speed, thereby quickly adjusting the seat position to move backward and folding the backrest.

[0035] Furthermore, the biological monitoring unit in this embodiment includes a camera, which is arranged on the crossbeam of the vehicle body's front windshield, facilitating a comprehensive observation of the situation inside the vehicle body cockpit. The camera can be a visible light wide-angle camera or an infrared wide-angle camera. The main control unit is electrically and communicatively connected to the camera, and is also electrically and communicatively connected to the door and window unlocking module and the electric window switch inside the compartment. When the driver locks the vehicle and the windows are closed, the main control unit, based on the received signals, detects the presence of people or animals and other organisms inside the vehicle, and controls the windows to open to a set degree to ventilate the interior of the vehicle, thus ensuring the life safety of the people or animals inside the vehicle.
