Indication of installation for car a accident location}

The present invention relates to a vehicle accident point display device for displaying the progress path of the vehicle on the road surface in the event of a car accident, more specifically, by detecting a shock occurring in the vehicle at the time of the accident occurs a predetermined point from the time of the accident By marking the paint on the surface of the road until the accident, the vehicle's accident point indication is made so that the progress of the vehicle can be identified as the paint sprayed on the surface of the road after the accident. Relates to a device.

In general, when a car collides with a car, collides with a person, or collides with an object while driving, a speed mark (tire mark) generated by tires and surface friction when the car stops suddenly to identify the accident spot It has been analyzed how much the accident vehicle slipped by operating the brake at what speed.

However, if the accident vehicle does not have a speed mark due to an accident while driving and when the accident vehicles collide with each other and the accident vehicle is located at a certain distance from the accident point, the accident occurred due to someone's fault. As a result, it becomes difficult to determine which route the accident vehicle was moving through.

For example, if vehicle A coming from the other side crosses the center line, collides with vehicle B, and then both vehicles A and B cross the other side, the driver B is not his fault if there are no witnesses. If this cannot be proved, it can be mistaken that the accident occurred due to the fault of vehicle B. Therefore, the cause of the accident needs to be identified realistically and clearly.

In particular, when an accident occurs near the center line, it is very ambiguous to know who caused the accident, so it takes a lot of time to deal with the accident, and it is necessary to spend a lot of money and time according to the struggle to find out. There is a problem.

Therefore, as described above, if a traffic accident occurs in relation to a vehicle such as an accident between a person and a vehicle, an accident between a vehicle and a vehicle, and an accident between an object and a vehicle, an alternative method for reasonably and reasonably identifying the cause of the accident is needed. Done.

The present invention has been made to solve the above problems, and the present invention allows the paint to be sprayed on the surface of the road at the same time as the movement of the vehicle for a predetermined time from the time of the occurrence of the vehicle accident, thereby making the first accident point reasonable and reasonable. The purpose of this study is to clarify the cause and to shorten the disputes caused by the cause and to shorten the time and period.

The above object is, according to the present invention, an air tank installed at a predetermined position under a vehicle bonnet and compressed with a predetermined amount of air, and applied to a vehicle at a predetermined position under the vehicle bonnet. A piezoelectric sensor configured to detect a shock and generate a signal, a solenoid valve electrically connected to the piezoelectric sensor to open an air tank to inject air when a signal is generated from the piezoelectric sensor, and open the valve of the air tank When the paint is sprayed with the air to be sprayed by the injection hole is installed at a predetermined position under the vehicle body spaced a predetermined distance from the at least one of the front wheels of the two front wheels toward the center of the axle, and the paint supplied by the air Car accident accident comprising a paint spraying means of the injection hole to be sprayed It is achieved by the display device.

Hereinafter, the configuration of the present invention will be described in Figures 1 to 3 as follows.

First, as shown in FIG. 1, an air tank 102 in which air is compressed is installed at a predetermined position under the bonnet 1 of the vehicle, and the solenoid valve 103 is installed in the air tank 102. ) To maintain a compressed state of a predetermined amount of air.

In addition, the piezoelectric sensor 104 is mounted at a predetermined position under the vehicle bonnet 1 so as to sense a shock applied to the vehicle 101 and generate a different signal intensity according to the intensity of the shock. Electrical connection with 103).

In addition, when the inlet of the air tank 102 is opened, the injection hole 105 for injecting paint together with air is installed at a predetermined position under the vehicle body spaced a predetermined distance from the front wheels 106 on both sides inwardly. (5) is preferably attached to the front wheel 106 adjacent to the axle, and includes any one of the one or the other side of the front wheel 106, or both.

In addition, the injection hole 105 is provided with a piston 112 which is directly transported when air is supplied from the first chamber 111 inside the injection hole 105 and the lower part of the piston 112 from the upper portion of the piston 112. It forms an air induction hole 115 of the 'T' type to guide the air to the second chamber 114 is formed in a predetermined size to the lower predetermined position in the inner side of the piston rod 113.

In addition, the lower portion of the air induction hole 115 is spaced apart from the air induction hole 115 so that the air introduced into the second chamber 114 can be sprayed to the outside of the injection hole 105 with the paint of the 'T' type The air injection hole 116 is formed. In addition, it is preferable to install an elastic member 117 on the lower part of the piston 112 of the first chamber 111 so as to hold the piston 112 upward. The paint spraying means of 105 is provided with a guide member 121 on the seating chuck 120 of the upper part of the injection hole 105 to seal the first chamber 111, and at a predetermined position on the bottom surface of the guide member 121. A guide rod 122 having a predetermined length formed in the longitudinal direction toward the lower portion is formed. A striking member 123 is disposed on a bottom surface of the guide member 121, and the striking portion 124 is formed of a first chamber ( It is disposed so as to be in close contact with the inner diameter surface of the 111, the guide rod 122 can be inserted into the air inlet hole 125 of the striking portion 124 formed on the bottom of the striking member 123, the striking portion 124 After forming the air induction hole 115 to penetrate through the air inlet hole 125 at a predetermined position of the outer side) In addition, the air is introduced into the second chamber 114. Further, an air injection path 126 having a predetermined diameter is formed from the lower portion of the air inlet hole 125 to the lower portion of the striking portion 124, and the air is terminated at the end thereof. To form a sprayed air injection hole 116, the lower end of the hitting portion 124 is formed to form a conical shape, as shown in Figure 4, a plurality of air injection holes 116 are formed on the outer surface of the conical In addition, the paint guide hole 127 penetrating the air injection path 126 is formed at a predetermined position on the outer diameter surface of the striking part 124 so that the paint of the second chamber 114 passes through the air injection path ( On the other hand, the second chamber 114 is accommodated in the receiving container 118 filled with the paint of a predetermined color, and the portion of the second chamber 114 (the first chamber 111) To receive a predetermined area of the lower end of the striking part 124 penetrating through the receiving hole 118 through the guide hole 128 formed in the bottom) An accommodation part 129 is formed in the lower part of the two chambers 114, and a discharge hole 130 having a predetermined size is formed in the lower part of the accommodation part 129. Here, the impact part accommodated in the accommodation part 129 is formed. 124 The lower end and the receiving portion 129 is preferably formed so that the separation space of a predetermined distance so that the paint sprayed into the air injection hole 116, respectively, can be combined into one stem.

In the second chamber 114, a receiving container 118 made of a relatively thin thin film aluminum capsule is disposed. As shown in FIG. 3, the first chamber 111 and the second chamber 114 are Make sure that they are screwed together so that they can be separated from each other.

Referring to the technique of the present invention made of the above configuration in Figures 1 to 5 as follows.

First, when an accident occurs while driving the vehicle 101, a shock is transmitted to the piezoelectric sensor 104 installed at a predetermined position under the bonnet 1, and thus the piezoelectric sensor 104 transmits an electrical signal to the piezoelectric sensor 104. Is applied to the solenoid valve 103 connected thereto.

At this time, the piezoelectric sensor 103 is able to detect the degree of the detected shock, the electrical signal is applied to the solenoid valve 103 in the slight shaking or shock, but the device of the present invention in the slight shaking or shock In order to solve problems such as waste of paint due to unnecessary use of the paint, it is preferable to set the solenoid valve 103 to operate only when a preset current is applied.

That is, since the piezoelectric sensor 104 generates an electric signal (current) as the degree of impact increases, the signal is small when a slight impact is applied to the vehicle, so that the strength of the current applied to the solenoid valve 103 is weak. In this case, since the strength of the current applied from the piezoelectric sensor 104 is weaker than the current required to operate the solenoid valve 103, the solenoid valve 103 is not operated, and the current is greater than the preset value. The solenoid valve 103 is operated so that the air tank 102 is opened so that the air of the compressed air tank 102 can be supplied to the injection hole 105.

As described above, as the air is instantaneously supplied to the injection hole 105, the piston 112 held by the elastic member 117 in the first chamber 111 of the injection hole 105 descends to the lower side. The lower end of the piston rod 113 extended to the lower portion of the piston 112 passes through the accommodation container 118 of the second chamber 114 as shown in FIG. 3B.

Accordingly, the air induction hole 115 formed inside the piston rod 113 guides the air introduced into the first chamber 111 of the injection hole 105 to the accommodation container 118 of the second chamber 114. The air and the paint supplied to the accommodation container 118 are sprayed to the outside through the air injection hole 116 in a mixed state.

Such a series of operations occur simultaneously with the impact of the vehicle, and the solenoid valve 103 operates only when the impact applied to the vehicle is greater than or equal to a predetermined size (about 10 seconds, about 15 seconds, etc.). Or by spraying paint on the road until the vehicle stops, it becomes clear how the accident vehicle was moved from the accident location.

On the other hand, in the embodiment of the present invention, the second chamber 114 of any one of the injection holes 105 of the injection holes 105 installed at both predetermined positions of the axle is always filled with paint of the same color to facilitate the direction of travel of the vehicle. It is desirable to be able to identify, and in addition, to the other injection port 105 is filled in different colors according to the vehicle type so that it is easy to discern which type of vehicle occurred in the case of an accident of different vehicles And, as an embodiment provided by the present invention, the description of the paint spraying means of another injection port 105 is as follows. First, the solenoid valve 103 is opened so that the air to the injection port 105 When supplied, the air rapidly lowers the striking member 123 through the through hole 131 of the guide member 121. At this time, the striking member 123 of the guide rod 122 inserted into the air inlet hole 125 Guidance As shown in FIG. 4, the impacting portion 124 penetrates the guide hole 128 below the first chamber 111 and strikes the accommodation container 118 accommodated in the second chamber 114 as shown in FIG. 4. Therefore, the striking part 124 is accommodated in the receiving part 129 of the lower part of the second chamber 114 as shown in FIG. 4B, and is supplied to the through hole 131 of the guide member 121. The air is introduced into the open air inlet hole 125 and at the same time, a part of the air is supplied to the air inlet hole 115 orthogonal to the air injection hole 116 to pressurize the paint in the accommodation container 118. Some of the air is exhausted to the outside through the air injection hole 116 and the discharge hole 130 of the accommodation portion 129 via the air injection path 126, the air supplied to the accommodation container 118 is The paint moves to the paint guide 127 with the paint as it expands within the containment vessel 118, and thus the paint moves to the paint guide 127. The air is injected into the air injection hole 116 together with a predetermined amount of air passing through the air injection path 126. Here, the lower end of the hitting portion 124 is formed in a conical shape as shown in FIG. A plurality of air spray holes 116 are formed on the outer diameter surface of the paint, and the paint is dispersed to each air spray hole 116 and then combined into one stem in a space below the receiving portion 129 and the hitting portion 124. At the same time as the load is injected through the discharge hole 130 of the receiving portion 129, it is possible to spray the paint even more powerful.

As described above, the present invention allows the paint to be sprayed on the road surface for a predetermined time from the time of the accident so as to grasp the path of the vehicle from the point of the accident to predict the cause of the accident and the direction of vehicle progress after the accident. It is a very good design to make it clear that even if it does not deal with the accident, it will not be inadvertently framed.
