Description

   Vehicle door warning device   

The invention relates to the technical field of automobile door opening warning lights.

Press, when the car parks to open the door, the accidents caused by accidentally opening the door when driving are heard, because to reduce the frequency of this situation, the better way is to strictly follow the two-stage door opening principle through car driving. .

Of course, the principle of two-stage door opening for car driving alone cannot reach the goal of almost zero accidents, because if the rear door can not be clearly and clearly recognized in the opening process, it will still cause accidents. occur.

At present, the warning means when the car door is opened is to use the door opening warning light when the car door is opened. Such warning lights are nothing more than the danger warning light when the door is opened, or the door blinking light set additionally installed in the door. Among them, the design that the double flashing yellow danger warning light is activated when the door is opened, and the vehicle coming behind will intuitively think that the vehicle in front is malfunctioning or needs to temporarily stop, and it is impossible to clearly determine that the vehicle in front is about to open the door. As for the additional installation of door-opening flashing light groups (commonly known as LED light bars) in each door, the door must be opened to a large extent before the flashing light group can be seen by vehicles coming behind. This type of door-opening warning flashing installed inside the door The lamp group is still not an ideal door warning light.

Therefore, how to make the vehicle clearly identify the vehicles coming behind in the process of opening the door to reduce accidents is the most important requirement of the present invention.

The present invention mainly provides a vehicle door opening warning device that can use any two types of light sources at the rear of an existing vehicle to actuate to form a rear to identify a vehicle that is about to open the door.

In order to achieve the above-mentioned expected purpose, the vehicle door opening warning device of the present invention is electrically connected to a vehicle tail light group. The tail light group includes at least a brake light, a direction light, or an additional door opening warning light, wherein the door opening warning The device system includes a control circuit unit and a closing unit. The control circuit unit is connected to and synchronized with each door sensing switch of the vehicle, and the control circuit unit is also electrically connected to the tail light unit of the vehicle, thereby acting as a vehicle. When the door is opened, the sensor switch is triggered, and at the same time, the control loop unit is activated to synchronously start any two types of light sources of the vehicle tail light group to strobe alternately to form a door warning light for rear vehicles to correctly recognize that the vehicle in front is about to open the door. Yes, the door-opening warning light is turned off through a closing unit to prevent excessive battery consumption of the vehicle.

The present invention relates to a vehicle door opening warning device. Please refer to Figures 1 to 3 for reference. The door opening warning device includes a control loop unit and a closing unit. The control loop unit can be directly used in conjunction with a driving computer, or It is used as a separate controller.

The control circuit unit is electrically connected and synchronized with the sensor switch 40 of each door 22 of a vehicle 20, and the control circuit unit is also electrically connected with two tail light groups 30 on both sides of the rear of the vehicle 20. The two tail light groups are at least Each includes a brake light 32 and a direction light, and a door opening warning light 34 can be added to the rear light group of the vehicle independently.

More specifically, the control circuit unit is electrically connected to the brake lights and the direction lights of the tail light group, or electrically connected to any two types of warning light sources of the current tail light group, and even to the independent door warning. The light 34 is electrically connected. The best embodiment is that the control circuit unit is electrically connected to the brake light (normally red light source) and the fault light (normally yellow light source). Any two light sources of the tail light group The synchronous staggered flashing operation is called a door-opening warning light, and an additional red and yellow synchronous flashing light source is added to the two taillights to set the door-opening warning light 34 independently. Preferably, the control loop unit of the aforementioned door opening warning device can still operate normally after the vehicle goes out, in other words, the door opening warning lamp triggered after the vehicle goes out can still operate normally.

In addition, in order to prevent the door opening time being too long, which causes the vehicle battery to be consumed, the closing unit design of the door opening warning device includes three types:

The first type: The shutdown unit is connected to the vehicle's hazard warning lights. By pressing the existing hazard warning light switch on the vehicle, the staggered blinking brake lights and fault lights are turned off.

The second type: the shutdown unit is connected to the vehicle's turn signal, and the brake light and turn signal on the same side are blinked by turning on the turn signal on the same side.

Third: The shutdown unit is an independent switch provided on the vehicle, and the staggered blinking brake lights and fault lights are turned off by triggering the independent switch.

Please refer to Figure 4 for reference. When the four door sensing switch circuits of the vehicle are independent and have no common detection point, the control flowchart of the control loop unit can be clearly known from Figure 4 when the left side of the vehicle ( (Right) When the front door or rear door is changed from closed to open, the door detection switch is activated and the left (right) door opening warning light is activated; otherwise, when the control circuit determines whether the left (right) front door or rear door is closed or not If the left (right) front door or rear door is not closed, the door opening warning lights (left (right) side brake lights and direction lights) continue to operate, if the left (right) front door or rear door is fully closed, then Turn off the left (right) side door warning light.

In conjunction with Figure 5, when the four door sensing switch circuits of the vehicle are designed as common detection points, the control flowchart of the control loop unit can be clearly understood from this figure. When any door of the vehicle is opened by a closed door At this time, the door sensing switch is triggered and the door open warning light is activated. Conversely, when the control circuit detects that both sides of the door (referring to the left and right front doors and the rear door) are not closed, the door open warning light will be retained to continue to warn the vehicle to come in. If the control circuit detects that the doors on both sides are closed, the door opening warning light is also turned off.

It can be known from the above that the structural opening effect of the vehicle door warning device of the present invention is as follows:

First, the door-opening warning lights of the door-opening warning devices all use the vehicle's existing taillights. There is no need to add additional light sources for door-opening warnings, so installation problems and vehicle appearance advantages can be avoided.

Second, the door opening warning light is activated by the red brake lights and yellow lights staggered in synchronization. In addition to the red and yellow two-color warnings, the visual effect of the car coming behind is remarkable, and it is also possible to avoid simply activating the direction lights. Turning the vehicle out and simply turning on the brake lights will cause vehicles coming in from behind to mistake the vehicle in front as braking.

Third, the door opening warning light starts synchronously when the door sensing switch is turned on. Therefore, when the door is opened slightly, the car coming from the rear can recognize that the vehicle in front is about to open the door. Naturally, the accident caused by the door opening can be greatly reduced. accident.

In summary, the vehicle door opening warning device of the present invention can flash the red and yellow two-color warning lights at the same time by touching the brake lights and the direction lights of the door opening warning lights during the first stage of the door opening. It is judged that the vehicle in front is about to open the door. The invention is not only unique and novel in structure, but also achieves unpredictable progressive effects. It has already met the requirements for the application for invention patents in China. The invention can be affirmed, and the granting of a quasi-patent at an early date is of great virtue.
