Example Embodiment

[0018] Example 1:

[0019] see figure 1 figure 2 , an automobile side door anti-collision safety early warning device, the safety early warning device consists of a distance sensor 01, an early warning device 04, an electromagnetic controller 03, and a processing chip 02, which are electrically connected to each other. 01 is installed in the rearview mirror of the car, and its energy beam emission direction is placed 1 degree outward from the "+" direction of the x-coordinate line of the car, so that the energy beam is emitted to the rear of the car; the distance sensor 01 measures the distance between the obstacle and itself Then transmit the distance signal to the processing chip 02 . When the processing chip 02 compares the distance with the preset value 1 and the preset value 2. When the distance is less than the preset value one, the electromagnetic controller 03 switches on the red warning light 24 and the buzzer 54 to make it work; when the distance is greater than ...

Abstract

The invention discloses an automobile door opening danger early warning device. The safety early warning device is composed of a distance sensor, an early warning device, an electromagnetic controllerand a processing chip which are electrically connected with one another, wherein the distance sensor is installed in an automobile rearview mirror, the energy wave beam emitting direction of the distance sensor forms an included angle of 1 degree outwards in the X coordinate line + direction of an automobile, and energy wave beams are emitted to the rear portion of the automobile. When the distance sensor in the automobile rearview mirror detects the distance between the distance sensor and an obstacle on the rear side, a signal is transmitted to the processing chip, the processing chip compares the distance with a preset value and sends an electric signal to the electromagnetic controller, and the electromagnetic controller controls the early warning device to send out different early warning signals. Therefore, the passenger can be effectively assisted in judging whether the door is opened or not.

Description

technical field [0001] The invention belongs to the field of automobile safety, and in particular relates to an early warning device for the danger of opening a door of an automobile. Background technique [0002] In recent years, the number of road vehicles in our country has increased day by day, and traffic accidents have also occurred frequently. A large part of the traffic accidents occurred at the moment when the car stopped and the door was opened. Observation, thus making it impossible for passengers in the car to determine the safety of opening the door and getting out of the car. At present, although the automotive industry has made great improvements in terms of safety, the installation of auxiliary driving equipment such as radar or panoramic cameras on cars has made great improvements in active safety and passive safety, but in terms of safety when opening the side door It's still almost blank. There are also some technologies that use the method of machine vi...
