Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1, as Figures 1-2 As shown, this utility model provides a technical solution: an automatic forced-opening door mechanical structure, including a door panel 1, one side of which is connected to the side wall of an A-pillar mounting plate 2, and a forced-opening door mechanical mechanism 3 for forcibly breaking the electromagnetic lock inside the door panel 1 is fixedly provided on one side of the A-pillar mounting plate 2; the forced-opening door mechanical mechanism 3 includes a servo motor 5 and a transmission shaft 6, the output shaft of the servo motor 5 is fixedly connected to the transmission shaft 6 through a coupling, and one end of the transmission shaft 6 is fixedly connected to a worm gear 7. 5. The motor mounting plate 2 is fixedly connected to the A-pillar mounting plate 2 via a motor mounting bracket. A bearing seat 8 is fixedly installed on one side of the A-pillar mounting plate 2. One end of the worm gear 7 passes through and is rotatably installed in the bearing seat 8. A center wheel 10 is installed on the side wall of the A-pillar mounting plate 2 via a bearing. A lead screw shaft is fixedly connected to one end of the center wheel 10. A lead screw sleeve 11 is sleeved on the lead screw shaft. Hinges 12 are fixedly connected to both sides of the lead screw sleeve 11. L-arms 13 are rotatably installed on each hinge shaft 12. Each L-arm 13 has a circular through hole, and each circular through hole contains a... A rotating shaft 14 runs through the structure, with cantilever arms 15 fixedly connected to both sides of the shaft 14. A pressure wheel 16 is rotatably mounted on one side of each cantilever arm 15. One end of the L-arm 13 contacts the door panel 1. A limit plate 4 is fixedly connected to the side wall of the A-pillar mounting plate 2 via a support block. The pressure wheel 16 contacts the bottom of the limit plate 4. A servo motor 5 drives the transmission shaft 6 to rotate, which in turn drives the worm gear 7, which in turn drives the worm wheel 9. The design of the worm wheel 9 and worm gear 7 achieves a large transmission ratio. This provides greater destructive force. The servo motor 5 can convert electrical energy into mechanical energy. The turbine 9 drives the rotation of the center wheel 10, which in turn drives the lead screw to rotate. The lead screw shaft drives the movement of the lead screw sleeve 11. Through the design of the lead screw, the conversion from rotation to linear motion is achieved, while a larger transmission ratio is achieved, increasing the destructive force. The movement of the lead screw sleeve 11 causes the L-arm 13 to rotate at a certain angle. One end of the L-arm 13 squeezes the car door, thereby forcibly breaking the car door connection and achieving the effect of mechanically forcing the door open.

[0023] In the present application, the occurrence of a safety accident is identified by a circuit system or a sensor. The circuit system can use BMI088 from Bosch, which is a high-precision 6-axis inertial measurement unit (IMU) that integrates an acceleration sensor and a gyroscope, capable of measuring acceleration and angular velocity information simultaneously, and can be used for various safety and driving assistance functions of vehicles, including accident detection. The sensor can use the AS-2000 series collision sensor from Autoliv, which has high sensitivity and fast response characteristics, and can accurately detect different types and intensities of collision accidents, widely used in the safety airbag control system of various types of vehicles. The sensor is usually based on mechanical, electronic or optical principles. When a vehicle collides, the sensitive elements inside the sensor will be deformed, displaced or have changes in electrical properties under the action of impact force, thereby generating corresponding electrical signals.

The servo motor 5 can realize the conversion of electrical energy to mechanical energy. The turbine 9 drives the rotation of the center wheel 10, the center wheel 10 drives the rotation of the lead screw, the movement of the lead screw sleeve 11 is realized by the lead screw, the design of the lead screw realizes the conversion from rotation to linear motion, and a large transmission ratio is achieved, increasing the destructive force. The movement of the lead screw sleeve 11 realizes the rotation of the L arm 13 by a certain angle, the L arm 13 presses the door from one end, thereby forcibly breaking the door connection and achieving the effect of mechanical forced door opening. The mechanism can be fixedly installed in the A pillar of the vehicle, without affecting the appearance of the vehicle, and the installation position can correspond to the electric mechanical lock of the vehicle itself, thereby achieving the problem of breaking the electric mechanical lock. If the circuit system fails simultaneously, the worm 7 is rotated by the mechanical wrench, the mechanical drive is continued, thereby achieving the forced door breaking manually, and a large destructive force is realized through the transmission chain designed.
