Vehicle door anti-collision device for new energy vehicle

Abstract

The invention discloses a vehicle door anti-collision device for a new energy vehicle. The vehicle door anti-collision device comprises a vehicle door body and a base located on one side of the vehicle door body; a moving groove is formed in one side of the base, a rack groove is formed in the inner wall of one side of the moving groove, and a rack is slidably connected to the inner wall of one side of the moving groove; one end of the rack extends into the moving groove, and a supporting rod is welded to one end of the rack; connecting rods are welded to the top of one side of the supportingrod and the bottom of one side of the supporting rod correspondingly; and one ends of the connecting rods are rotatably connected with fixing plates, and the two fixing plates and the vehicle door body are fixedly mounted. The vehicle door anti-collision device is easy to operate, the two fixing plates are moved out of the moving groove, thus the two fixing plates and the vehicle door body can befixedly mounted, then when the vehicle door body is collided, the impact force applied to the vehicle door body can be offset through a first compression spring and a second compression spring, at themoment, the vehicle door body can be protected from the angle of a physical structure, and thus the vehicle door body is not prone to being collided.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a door anti-collision device for new energy vehicles. Background technique [0002] Publication number: CN108032801A discloses a door opening anti-collision device of a new energy vehicle in the technical field of automotive supplies, including a distance measuring sensor, a vehicle speed measurement module, a digital-to-analog converter, and a control unit. The control unit is also connected to the distance display module, The timer, the brake unit and the door drive motor are connected; the distance measuring sensor is used to measure the distance signal between the door of the new energy vehicle and the car or pedestrian coming from behind. A short pulse in the measurement logic circuit, the ultrasonic receiver receives the reflected wave reflected by the obstacle when the ultrasonic wave encounters an obstacle, and also sends a short pulse to the measurement logic...

[0002] Publication number: CN108032801A discloses a door opening anti-collision device of a new energy vehicle in the technical field of automotive supplies, including a distance measuring sensor, a vehicle speed measurement module, a digital-to-analog converter, and a control unit. The control unit is also connected to the distance display module, The timer, the brake unit and the door drive motor are connected; the distance measuring sensor is used to measure the distance signal between the door of the new energy vehicle and the car or pedestrian coming from behind. A short pulse in the measurement logic circuit, the ultrasonic receiver receives the reflected wave reflected by the obstacle when the ultrasonic wave encounters an obstacle, and also sends a short pulse to the measurement logic circuit, and the distance between the ultrasonic transmitter and the obstacle is determined by the width of the two sets of short pulses , the measurement method is accurate and reliable, will not produce distortion of the measurement results, and can effectively detect obstacles, but it can only provide an alarm function, but does not have a protective physical structure, so when the driver is distracted, it is easy to collide , which in turn will cause damage to the car, so we propose a door anti-collision device for new energy vehicles to solve the above-mentioned problems
