[0027] Working principle of the utility model: when the device is actually used, the rearview mirror body 2 connected to the mirror body handle 3 is first fixed to the two sides of the front of the new energy vehicle through the fastening screws 5 of the mirror body handle 3 to ensure the firmness of the rearview mirror and the new energy vehicle. Since the internal surface of the connection between the rearview mirror body 2 and the screw 4 is provided with threads, the driver can adjust the visible position of the rearview mirror body 2 by rotating the mirror body handle 3 around the screw 4. When the new energy vehicle is subjected to external impact force, the torque sensor 9 responds by sensing the size of the impact force. If the impact force exceeds the safety threshold set by the torque sensor 9 itself, the torque sensor 9 will send an electrical signal at the same time. The power motor 101 in the mirror body protection device 1 and the reminder system in the driver's car, if the driver does not make a corresponding obstacle avoidance response to the reminder in time, the power motor 101 at the bottom of both sides of the inner cavity of the rearview mirror body 2 will start immediately, and the power traction rope 102 connected to the output shaft of the power motor 101 will be wound, stretched and straightened with the rotation of the output shaft, so that the limiting pulley 104 fixedly connected to the surface of the power traction rope 102 moves in the limiting slide rail 8. At this time, the protective folding baffle 103 folded and connected to the top of the limiting pulley 104 and located in the recovery groove 6 is stretched at the same time as the limiting pulley 104 is certain, until the power motor at the top of the rearview mirror body 2 The power traction rope 102 on the surface of 101 is completely detached, and the limiting pulley 104 at the end of the protective folding baffle 103 just slides to the end of the limiting slide rail 8, and the power motor 101 stops running. At this time, due to the sliding of the limiting pulley 104, the protective folding baffle 103 is completely stretched to cover the entire mirror surface 7, and the limiting groove 105 at the bottom of the protective folding baffle 103 is connected and fixed with the limiting buckle 11 at the bottom of the rearview mirror body 2 to ensure the stability of the protective folding baffle 103 and the mirror surface 7 and protect the mirror surface 7; when the new energy vehicle is about to hit an external object during active movement, the ultrasonic rangefinder 1 on the surface of the rearview mirror body 2 0 determines whether the distance is within the safety threshold according to the distance between the external object and the rearview mirror. If the safety threshold is exceeded, the mirror handle 3 and the reminder system in the new energy vehicle are promptly reminded to the driver through an electrical signal. When the driver fails to make a timely obstacle avoidance response according to the reminder, the mirror handle 3 immediately rotates around the screw 4 to make an obstacle avoidance response when receiving the electrical signal, so that the rearview mirror body 2 is safe in the active obstacle avoidance state. The torque sensor 9 closes the mirror body protection device 1 according to the real-time measurement of the safety range of the external environment, and the ultrasonic rangefinder 10 drives the mirror handle 3 to drive the rearview mirror body 2 to restore the original position according to the safety distance of the external environment in real time.
