Description

Car door opening warning device

This invention is about a car door opening warning device that can emit a warning flash through the car's side mirror before the driver or passenger reaches out to open the door.

In crowded streets, the action of opening the car door when getting out of the car often causes unexpected collisions. For example, pedestrians, bicycles, motorcycles, and even cars cannot predict whether the car door on the roadside will suddenly open when they are moving forward. Once the door is suddenly opened, the people and cars behind them will often not be able to react in time, resulting in collision injuries. Moreover, the faster the speed of the people and cars behind them, the greater the injuries they will suffer.

However, when the doors of existing cars are opened, there is no warning signal to warn people or cars outside. People or cars on the road cannot predict which car on the roadside will suddenly open its door, causing collision danger. Therefore, based on this situation, the creator of this invention must be able to warn people and cars outside the car in advance when the car opens its door from the inside to the outside, so that the people and cars that receive the warning can slow down or avoid it.

In view of this, the main purpose of this invention is to propose a feasible technical solution that can provide early warning to people and vehicles around the car before the car door is about to open.

To achieve the above purpose, the invention proposes a car door opening warning device, including: A warning module, which is arranged on a side rearview mirror outside the car, and has a light-emitting element arranged on the side rearview mirror, and a signal receiving element electrically connected to the light-emitting element; and a detection module, which is arranged in a door panel groove on which a door opening element is installed, and has a control circuit board, a sensing element electrically connected to the control circuit board, and a signal transmitting element; when the sensing element detects that a person's finger enters the sensing range, it will send an activation signal to the signal receiving element through the signal transmitting element, and after the signal receiving element receives the activation signal, it will immediately drive the light-emitting element to emit a warning flash.

With this structure, when the driver or passenger in the car reaches out to open the door, once the detection module detects the driver or passenger's finger approaching, it will emit a strong warning flash through the warning module installed on the side mirror of the car in advance to warn the surrounding pedestrians or vehicles that the door of this car is about to be opened, thereby achieving the function of door opening warning and reducing the risk of collision.

In this creation, the light-emitting component is an annular light ring located inside the mirror holder shell of the car's side rearview mirror, or an annular light ring located outside the mirror holder shell of the car's side rearview mirror. ; In addition, the light-emitting component may also be one or more warning lights located on the outer side or bottom of the mirror base housing of the side mirror of the vehicle.

In this invention, the signal transmitting element transmits the activation signal to the signal receiving element by wired transmission or wireless transmission.

The detailed features and advantages of this invention are described in detail in the implementation method below. The content is sufficient for anyone familiar with the relevant technology to understand the technical content of this invention and implement it accordingly.
