Description

A system for safely opening a car door

technical field

The invention belongs to the technical field of automobile safety, and in particular relates to a system for safely opening a car door.

Background technique

There are more and more types and quantities of motor vehicles on the road. When vehicles come and go, accidents will be caused if you are not careful. Accidents caused by improper "opening the door" are very common, and once they happen, it may be a tragedy.

Whether driving a car or taking a car, you have to get out of the car and open the door. This seemingly simple thing has a very deep doorway. If you open the door inadvertently, a passer-by on a bicycle will be knocked into the air; maybe if you open the door inadvertently, the door will be smashed by the fast car coming from behind, and the person who is getting off the bus will also be knocked into the air. Although "opening the door" is only a small action, it has the fatal danger of killing people. Drivers often know what to do while driving. However, many people will forget to check the situation outside the car and open the door hastily when they open the door and get off the car, resulting in tragedy. In China, incidents caused by "opening the door" are not uncommon, and they happen all the time.

Known as the "Bicycle Kingdom", the Netherlands is a country with more bicycles than the population, so bicycles can be seen almost everywhere on the roads, but there are very few accidents caused by "opening the door". Because in the Netherlands, drivers always open the door with the hand that is farthest from the door. This is the best way to open the door to avoid such accidents, that is, left-hand drive with the right hand, right-hand drive with the left hand—— The door method (Dutch Reach door opening method invented by the Dutch) is widely popularized and used.

The Dutch Reach door opening method is not done casually. When you open the door with the hand farther away from the car door, your upper body will turn naturally, and your head and shoulders will look out naturally. . First of all, the eyes will observe through the rearview mirror, and then look backward when turning around. This complete action can avoid many unnecessary accidents, no matter whether it is a bicycle or a motor vehicle coming from behind. However, if you open the door with the hand that is closer to the door, the driver will naturally push the door out without checking the sudden movement of the car coming from behind, which will easily scare the people behind and even cause serious accidents.

Although many countries have added the method of safely opening the door to one of the items of the driver's license test, few people strictly implement it, and few people can form a good habit of "Dutch Reach door opening method". Even though the trainees are strictly required to adopt the "Dutch Reach Door Opening Method" during the driving training and test, when they get their driver's license and drive their own car, they have already forgotten some rules and eliminated some driving constraints, and gradually become more mature. It has become a bad driving habit, and it has accumulated over time, laying many hidden dangers for your own safe driving.

Contents of the invention

The technical problem to be solved by the present invention is to adopt a safe door opening system, force the driver and passengers to adopt the "Dutch Reach" door opening method, and open the door safely, so as to provide protection for the safety of themselves and others.

The technical scheme that the present invention solves its technical problem adopts is:

A system for safely opening car doors, characterized in that it is arranged on four doors and a car body of a car; it includes: a first unlocking button, a pressure unlocking groove, and a second unlocking button respectively controlled by a first unlocking button set on any car door. The door lock, the second door lock, and the third door lock, the three door locks are opened independently of each other, and only when the three door locks are opened at the same time, the door will be opened; the first unlocking button and the pressure unlocking slot are placed The inner side of the door close to the front of the car needs to be operated by the person who opens the door with one hand after turning around. The second unlocking button is placed above the first unlocking button and the pressure unlocking slot, and is set so that the person who opens the door needs to turn around and turn around to allow the other hand to approach. And press the position, so that the door opener must keep his hands apart to keep pressing in two directions to open the door when he turns around and looks back.

In the above technical solution, each door is also provided with a door opening angle controller, and the door opening angle controller is activated when the first door lock, the second door lock, and the third door lock are simultaneously opened, and is set so that the door opening angle varies with each other. Thrust is limited from small to large thresholds; that is, as the thrust increases to the first force threshold, the door rotation angle slowly increases to 15 degrees; when the thrust is greater than the first force threshold, the door will temporarily stop rotating, Only when the thrust continues to increase to the second force threshold, the door rotation angle will continue to increase; the maximum thrust limit threshold when the door is fully opened is the third force threshold, and the second force threshold reaches the third force threshold. The door rotation angle within the threshold range is freely controlled by the passenger and the driver according to the conditions outside the vehicle.

In the above technical solution, along the direction from the front of the car to the rear of the car, the first door lock, the second door lock, and the third door lock are spaced apart vertically along the door, and are located on the outer frame of the door facing the rear of the car so that they can be locked in the locked state. Combined with the car body; the first unlocking button and pressure unlocking slot are set on the lateral control panel on the inner side of the door, and the first unlocking button is located behind the pressure unlocking slot; the distance between the first unlocking button and the pressure unlocking slot is set for passengers or drivers The thumb of one hand presses the first unlocking button, and the remaining four fingers of the one hand are placed in the pressure unlocking groove to apply the set pressure to open the first door lock and the second door lock at the same time;

For the driving position and the co-pilot position, the second unlocking button is located at the middle upper part of the B-pillar of the vehicle body behind the door and below the seat belt buckle; for the doors on both sides behind the driving position, the second unlocking button is located at the same The upper middle part of the rear car body where the door is combined and is located below the seat belt buckle; the second unlock button is set so that the person who opens the door needs to turn around and turn his head at the same time to approach and press the second unlock button with the other hand nearby, and at the same time Use one hand as described to keep pressing the first unlock button and press the unlock slot.

In the above technical solution, the door opening angle controller includes an angle sensor, a limit actuator, and an angle controller. The limit actuator is installed at the hinge of the door; the angle sensor is located between the door and the car body, and is used to detect the opening of the door. The angle of the door opening; the change of the opening angle of the door with the force of opening the door is controlled by the controller.

Thus, in the safe door opening system of the present invention, the first door lock, the second door lock, and the third door lock are respectively controlled by the first unlock button, the pressure unlock groove, and the second unlock button, and the three door locks are independent of each other, and Only when the three door locks are opened at the same time, the door will open, that is, the door will only open when the first unlock button and the second unlock button are pressed at the same time, and a certain pressure is applied in the pressure unlock groove.

The first unlocking button is located behind the pressure unlocking groove (near the side of the door lock). Only when the thumb presses the first unlocking button and the other four fingers are placed in the pressure unlocking groove can the first door lock and the second door be opened at the same time. Lock. That is: the driver and the passengers behind the driver must use the right hand to open the first door lock and the second door lock when opening the door, and the co-driver and the passengers behind the driver must use the left hand to open the first door lock and the second door when opening the door Lock. Therefore, it is necessary to turn around to unlock the first door lock and the second door lock before getting out of the car.

The second unlocking button is located at the middle upper part of the B-pillar of the automobile, below the seat belt buckle. The doors will only open when all three door locks are unlocked at the same time. Therefore, the driver and the passengers behind the driver must use the left hand to open the third door lock when opening the door, and the co-driver and the passengers behind the driver must use the right hand to open the third door lock when opening the door. Since there is a certain distance between the second unlock button and the first unlock button and the pressure unlock groove, the left and right hands need to be opened to a certain extent when opening the three door locks at the same time, and only the person who turns around to open the first door lock and the second door lock Turning your head at the same time is the most comfortable way to open the door before getting out of the car. Thereby, the drivers and passengers are restrained from turning their heads and driving behind pedestrians and oncoming vehicles before getting off the vehicle.

The door opening angle controller controls the rotation angle of the door when the door is opened. When the first door lock, the second door lock and the third door lock are opened at the same time, as the thrust increases to F1, the door rotation angle slowly increases to 15 degrees; when the thrust is greater than F1, the door will temporarily stop rotating, Only when the thrust continues to increase to F2, the door rotation angle will continue to increase. The time for the thrust to increase from F1 to F2 gives the driver and passengers who are opening the door and getting off the car a careful look at the situation of pedestrians and oncoming vehicles behind, so as to avoid traffic accidents.

Compared with the prior art, the present invention mainly has the following advantages:

1. Through the safe door opening system, the present invention forces the driver and passengers to turn around and turn their heads before getting out of the car, and gives a certain amount of time to carefully see the situation of pedestrians and incoming cars behind. The system strictly requires the driver and passengers to use The Dutch Reach door opening method improves traffic safety and protects the life and property of drivers and passengers as well as the safety of public transportation.

2. The present invention does not need to change the structure and system of the car itself, and has low cost and reliable performance. It integrates the necessary car safety and civilized operation into the car control system, and forces drivers and passengers to form good habits, which can effectively avoid many traffic accidents. Prevent accidents from happening.

detailed description

The present invention will be further described below in conjunction with implementation examples and accompanying drawings.

A system for safely opening a car door provided by the present invention includes a first car door lock 1, a second car door lock 2, a third car door lock 5 and Door opening angle controller.

In the safe door opening system, the first door lock 1, the second door lock 2, and the third door lock 5 are respectively controlled by the first unlock button 3, the pressure unlock groove 4, and the second unlock button 6, and the three door locks are independent of each other. .

The safe door opening system, only when the three door locks are opened at the same time, the door will be opened, that is: when the first unlock button 3 and the second unlock button 6 are pressed at the same time, and a certain pressure is applied in the pressure unlock groove 4, The door will only open.

The first unlocking button 3 is located behind the pressure unlocking groove 4 (near the side of the door lock). Only when the thumb presses the first unlocking button 3 and the other four fingers are placed in the pressure unlocking groove 4 can the first door lock be opened at the same time. 1 and the second door lock 2. That is: the driver and the passenger behind the driver must use the right hand to open the first door lock 1 and the second door lock 2 when opening the door, and the co-driver and the passengers behind the driver must use the left hand to open the first door lock 1 and the second door lock when opening the door. Second door lock 2. Therefore, it is necessary to turn around to unlock the first door lock and the second door lock before getting out of the car.

The second unlocking button 6 is located at the middle upper part of the B-pillar of the automobile, below the seat belt buckle. The doors will only open when all three door locks are unlocked at the same time. Therefore, the driver and the passengers behind the driver must use the left hand to open the third door lock when opening the door, and the co-driver and the passengers behind the driver must use the right hand to open the third door lock when opening the door. Because there is a certain distance between the second unlocking button 6 and the first unlocking button 3 and the pressure unlocking groove 4, the left and right hands need to open a certain range when opening three door locks at the same time, and only turn around to open the first door lock and the second door lock. Turning the head while the door is locked is the most comfortable way to open the door before getting out of the car. Thereby, the drivers and passengers are restrained from turning their heads and driving behind pedestrians and oncoming vehicles before getting off the vehicle.

The door opening angle controller includes an angle sensor, a limit actuator, and an angle controller. The limit actuator is installed at the hinge of the door; the angle sensor is located between the door and the car body, and is used to detect the opening angle of the door; the opening angle of the door is controlled by the controller according to the force of opening the door.

The control strategy of the angle controller is that when the first door lock 1, the second door lock 2, and the third door lock 5 are simultaneously opened, as the thrust increases to F1, the door rotation angle slowly increases to 15 degrees; When the thrust is greater than F1, the door will temporarily stop rotating (during this process, the slope of the straight line where the door rotation angle changes with the thrust is k1). Only when the thrust continues to increase to F2, the door rotation angle will continue to increase ( During this process, the slope of the straight line where the door rotation angle changes with the thrust is k2). The time for the thrust to increase from F1 to F2 gives the driver and passengers who are opening the door and getting off the car a careful look at the situation of pedestrians and oncoming vehicles behind, so as to avoid traffic accidents. When the thrust reaches F3, the door remains fully open. In this embodiment, the fully open state is 85°. F1>0, and F1<F2<F3.

The limit actuator is composed of a door hinge and two springs. Wherein, the elastic constant of the first spring is k1, and the elastic constant of the second spring is k2-k1.
