Description

Door delay opening and safety warning system

The invention relates to a door opening system, in particular to a method in which a door delay is forcibly unlocked after a few seconds, and at the same time, a driver and other vehicles are used to drive the door and the door to be opened is delayed and the safety warning system is opened.

According to the accident, the accident of the car is not only during the driving period, but also when the car stops moving, it may cause accidents, especially when the passenger gets off the car and forgets to check the rear car and directly open the car to get off the car. The opened door is easy to be behind. The car caused a collision and caused a car accident. Traditionally, when driving off the vehicle, the rear view mirror next to it is used to check whether there is a rear car, but the rear passenger cannot clearly see the person and the car from the rear by the back light. For example, the passenger in the rear seat cannot see the reflected image of the rear view mirror because of the poor angle of sight, and can only turn and look backwards, which is neither clear nor quite convenient. Even the passengers in the front seat's passenger seat will be adjusted because the rear view mirror responds to the driver's line of sight, so that the passenger seat passenger can't see the reflection image of the rear view mirror to find out if there is any car behind the car. Therefore, the passengers in the front and rear seats of the car, and even the driver, can easily cause accidents when people and cars collide with the rear when the door is opened.

Therefore, some companies have developed patents that warn the rear of the vehicle and the door is about to open. For example, the Republic of China New Patent Bulletin No. M336891 "Automotive door opening" The safety warning device is equipped with a distance detecting radar around the automobile and connected with the central locking circuit. When the parking is to open the door and the detecting radar detects that there is a vehicle behind, the control circuit and the central locking circuit respectively A voice warning and a delay signal were issued to remind the driver that there was a car behind, and the door could not be opened at the first time. However, the patent was issued to prompt the driver and control the central locking, but did not provide warning to the rear car, thus still causing Dangerous possibilities. And, in the Republic of China, the new patent publication No. M419704, "Getting the vehicle to open the door collision warning device", comprising a measuring unit disposed on the rear view mirror, a handle sensing unit disposed on the door handle, and a warning unit disposed in the vehicle And the control unit, when an object is approached behind the equivalent measuring unit, the user can be alerted when the door handle is touched. The patent still indicates the design of the driver, and does not provide warning to the rear car. In addition, the "Automotive door opening warning stop device" of the Republic of China New Patent Announcement No. M471399 is a stop mechanism, which is when the passenger touches the door handle sensing element on the door handle and the door is opened. The hand sensing element turns on the electromagnetic coil, so that the stopper is pushed up, so that the door cannot be opened immediately, and after the set time elapses, the power is cut off, the stop is dropped, and the door can be smoothly opened. The stop mechanism mainly blocks the door, so that the door cannot be opened immediately, so as to avoid the door being opened too quickly, causing damage to the rear of the car.

In addition, the "Automotive Door Opening Warning Device" of the Republic of China New Patent Announcement No. M315174, when the rear end face of the door leaves the door post, is controlled by a switch, and the warning light on the control door is illuminated; further, the Republic of China The new patent publication No. M320506 "door opening quick warning device" is provided by the touch portion of a touch timing circuit on the door handle, and when the occupant pulls the driver to shake hands, the control of the touch timing circuit is used. Start the alarm on the end of the door and issue a warning to the outside car as soon as possible. In addition, the Republic of China new patent announcement No. M419704 "Get off the door and open the collision warning device" is attached to the rear view mirror module. Set The measuring unit and the door handle are provided with a handle sensing unit, and the warning unit is built in the vehicle. When an object is approached behind the equivalent measuring unit, the user can be alerted when the door handle is touched, thereby avoiding an accident of impact. However, when the above three patents were actually implemented, when the vehicle door warning light was found to the vehicle, the fact that the vehicle door was pushed out was actually in progress. The vehicle that was too close to the door would still have a dodge collision. The accident on the door.

The Republic of China new patent announcement No. M421902 "Radar door collision avoidance and rear arrival warning system" reveals the radar door collision avoidance and rear arrival warning system. When the passenger wants to open the door, if the radar device detects movement The object transmits the signal to the controller to lock the door and sounds the user through the buzzer; when the radar device senses no moving object, the controller unlocks the door; There is still a blind spot in use, that is, when the object continues to move, approach and pass behind the vehicle, the controller will continue to lock the door and make the door unable to open.

Although such a patent will generate a warning to remind the car, the actual situation is that the driving of the rear vehicle often fails to determine whether the vehicle is about to open when the vehicle is stopped ahead, and the door opening time is extremely short. In particular, the locomotive knight is more likely to cause accidents because of misjudgment and quick rushing. It should be noted that in addition to the above patents, there are still many patent documents that reveal the control to the opening of the door. However, many unfortunate human injury incidents are also frequent. It is often the case that driving a central control lock that maliciously controls the vehicle, so that the door cannot be opened, or it cannot be opened in a short time. Such malicious human factors cause a goodwill door delay. Opened to remind passengers of the need to pay attention to the patented technology of the rear car, which became the main reason for the inability to implement and implement.

(102) the warning module generates a first alert state;

When the foregoing steps are performed, the control module 33 receives the power to generate an activation signal, and the alarm module 34 receives the activation signal transmitted by the control module 33, and then generates the first warning state, and the first warning state may be In order to express the warning state of "the door is about to open" by means of text, pattern, graphic or voice, to remind the rear vehicle or pedestrian to warn that the door of the vehicle of the present invention is about to be opened, but the door has not been opened yet;

(103) the timing module performs a countdown;

(104) ending the countdown to unlock the door lock circuit;

When the above steps are performed, the timing module 32 receives the electric energy and starts counting down. The counting time is based on the actual demand, and may be at least 1 second to a plurality of seconds. When the counting timer ends, the timing module 32 The operation causes the door lock circuit 2 to be unlocked. At this time, the handle mechanism 21 can be operated at any time and then the door is opened.

(1005) the control module senses that the door lock circuit has been forcibly unlocked, and at the same time, any of the handle mechanisms act to generate an action signal;

(106) The alert module receives the action signal to generate a second alert state.
