Door safety device

This creation is related to vehicle equipment, especially a door safety device.

According to the current traffic accidents on the road, there is a kind of driving for the car or the passengers before getting off the bus. If they do not pay attention to whether there is a car at the rear, they will open the door first, so that the rear car will chase the door. accident.

Analysis of the reasons for traffic accidents caused by improper driving of the driver's door or the passengers is caused by the lack of attention to the traffic conditions before driving. However, in any case, the traffic safety education for drivers and passengers may still be inadvertent. The situation of opening the door without paying attention to it occurs.

Therefore, how to directly limit the opening of the vehicle door to prevent such a traffic accident caused by improper opening of the door is an urgent problem for the relevant industry.

It can be seen that there are still many shortcomings in the above-mentioned household items, which is not a good designer and needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional door safety devices, the creators of this case are thinking and improving and innovating, and painstakingly researching them. After that, I finally successfully developed this door safety device.

The purpose of this creation is to provide a door safety device that can detect the exterior of the vehicle during the opening of the door to determine whether to limit the angle at which the door is opened to establish a non-driver or passenger. Judging, and quite objective door opening mechanism, can improve traffic safety.

The door safety device capable of achieving the above-mentioned creation purpose comprises: a locking device disposed between a vehicle body and each door for controlling the angle at which the door is opened; a detector disposed on the a predetermined position outside the vehicle body for detecting whether a vehicle is in proximity within a predetermined range outside the vehicle body; a control unit is disposed in the vehicle body and electrically connected to the locking device and the detector The detecting unit drives the detector to detect and feed the detection result to the control unit, and the control unit determines whether the locking device is activated according to the detection result, thereby limiting the opening angle of the door. size.

1 is a top view of the safety device for a door; FIG. 2 is a flow chart of the door safety device; FIG. 3 and FIG. 4 are schematic views of the door safety device.

Referring to FIG. 1 and FIG. 2, the door security device provided by the present invention mainly includes a locking device 1, a detector 2 and a control unit 3, wherein the locking device 1 is respectively connected to a vehicle. Between the vehicle body 4 and each of the doors 41, the angle at which the door 41 is opened is controlled.

The detector 2 is disposed at an appropriate position outside the vehicle body 4 of the vehicle for detecting whether there is a vehicle in a predetermined range outside the vehicle body 4; in the embodiment, the detectors 2 are It is disposed on the bumper or the vehicle body 4 behind the vehicle body 4, and is detected within a certain range obliquely rearward.

The control unit 3 is a microprocessor disposed at a predetermined position in the vehicle body 4 of the vehicle, and is electrically connected to the locking device 1 and the detector 2 to control the locking device 1 and the detector. Actuator 2 of the mover.

Therefore, the above is the introduction of the components of the door safety device and the assembly method thereof according to a preferred embodiment of the present invention, and then the manner of use and the advantages thereof are as follows: First, when the vehicle body 4 travels at a speed of 0. When the door 41 is opened, the control unit 3 activates a signal to drive the detector 2 to detect the oblique rear of the vehicle, and returns the result of the moving object to the control unit 3, so that the control unit 3 It is judged whether or not the lock device 1 is actuated.

Referring to FIG. 3 and FIG. 4, when the result of the detection by the detector 2 is that there is a moving object behind the vehicle, the control unit 3 activates the locking device 1 to make the locking device 1 facing the door 41. Produce a limiting angle Force, as a result, forcing the door 41 to be opened only a small angle (eg, 20 degrees), it cannot be opened to a larger angle; if the detector 2 detects the result, there is no movement behind the vehicle When the object is in motion, the control unit 3 notifies the locking device 1 to stop, and the door 41 can be completely opened at this time; thereby, it is possible to avoid the situation that the rear vehicle collision occurs when the door 41 is opened.

In addition, in the above embodiment, a warning device (not shown) may be further disposed inside the vehicle body 4 of the vehicle, and the alarm device is electrically connected to the control unit 3, when the control unit 3 notifies When the locking device 1 is actuated, the warning device can simultaneously generate an alarming action, such as generating a light, a sound, or simultaneously generating a light or a sound to remind the driving or passenger of the door 41 to be opened.

Another embodiment of the present invention may further include an unlocking device (not shown) disposed inside the vehicle body 4 of the vehicle and electrically connected to the control unit 3 and the locking device 1 when the vehicle is on the roadside. When parking, because the vehicle is too close to the lane, it is easy for the detector 2 to detect that there is a moving object behind the vehicle body 4, thereby causing the driver or the passenger to completely open the door 41. At this time, the driver or the passenger can By pressing the unlocking device, the unlocking device sends a signal to the control unit 3, and the control unit 3 notifies the locking device 1 to stop, and the door 41 can be completely opened, thereby avoiding driving. The situation in which a person or passenger cannot open the door 41 occurs.

In another embodiment of the present invention, the control unit 3 can be electrically connected to a central locking lock existing inside the vehicle body 4. When the vehicle body 4 travels at a speed of 0 and the door is When the 41 is turned on, the control unit 3 activates a signal to drive the detector 2 to detect the oblique rear of the vehicle, and returns the result of whether there is a moving object to the control unit 3, so that the control unit 3 determines whether the control unit 3 determines whether Turn the central lock on or off.

The detailed description above is a detailed description of one of the possible embodiments of the present invention, and the embodiment is not intended to limit the scope of the patents, and the equivalent implementations or modifications that are not included in the spirit of the present invention should be included in The patent scope of this case.

To sum up, this case is not only innovative in terms of space type, but also can enhance the above-mentioned multiple functions compared with customary articles. It should fully comply with the statutory new patent requirements of novelty and progressiveness, and apply in accordance with the law. This new type of patent application, to encourage creation, to the sense of virtue.
