본 고안은 주차시나 골목길 서행시 차체의 하부에 있는 장애물이 존재하는 경우, 이를 감지하여 운전자에게 알려주는 차체 하부 장애물 감징장치이다.The present invention detects the presence of an obstacle in the lower part of the body when parking or slowing down alleys, it is a lower body obstacle obstruction device to inform the driver to detect this.
최근에 차량은 증가하는데 비하여 주차장은 한정되어 있어서, 자동차를 장애물이 많은 골목길이나 주차장이 아닌 곳에 주차시키는 경우가 늘고 있다. 이렇게 주차장이 아닌 곳에는 돌과 같은 자연 장애물이 많기 때문에, 차체가 이들 장애물과 충돌되어 손상받게 되는 경우가 빈발하고 있다. 특히, 장애물이 차체의 중앙하부에 놓이게 되는 경우는 운전자의 시야에서 벗어나 있기 때문에 이와 같은 현상이 더욱심하다.In recent years, the number of cars has been limited, whereas the number of parking lots is limited, and the number of cars is parked in an alley or a parking lot where there are many obstacles. Since there are many natural obstacles such as stones in the non-parking area, it is common for the car body to collide with these obstacles and be damaged. In particular, when the obstacle is placed under the center of the vehicle body, such a phenomenon is more severe because it is out of the driver's field of view.
본 고안은 상기와 같은 경우에 대처하기 위하여 안출된 것으로, 골곡길 주행시나 주차시 차체 하부에 장애물이 존재하는 경우을 알려주므로써 운전자가 인식하지 못한 장애물과의 충돌로 인한 차체의 손상을 방지하는 것을 목적으로 한다.The present invention was devised to cope with the above cases, and it is intended to prevent damage to the vehicle body due to collision with obstacles not recognized by the driver by informing the case that there is an obstacle under the vehicle body when driving on a valley road or parking. It is done.
도 1은 본 고안의 일 실시예에 의한 차체 하부 장애물 감지장치의 구성도.1 is a block diagram of a lower body obstacle detection apparatus according to an embodiment of the present invention.

[실시예]EXAMPLE
이하, 상기와 같은 구성을 가진 본 고안의 바람직한 일 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention having the configuration as described above will be described in detail.
본 실시예를 설명함에 있어, 서두에서 설명된 종래의 기술과 동일한 본 고안의 구성에 대해서는 동일한 부호를 사용사며, 명료성을 위하여 가능한 종래와 중복되지 않게 개선된 부분만을 주로하여 설명한다.In the description of the present embodiment, the same reference numerals are used for the configuration of the present invention, which is the same as the conventional technology described at the outset, and only the improved parts will be described so as not to overlap with the prior art as possible for clarity.
첨부도면의 도 1은 본 고안의 일 실시예에 의한 차체 하부 장애물 감지장치의 구성도이다.1 of the accompanying drawings is a block diagram of an obstacle detection device under the vehicle body according to an embodiment of the present invention.
도시된 바와 같이, 본 실시예의 차체 하부 장애물 감지장치는 차체(1)의 전방하부에 설치되는 발광부(2), 이 발광부(2)의 정후방에 마주보며 설치되는 수광부(3)와, 상기 수광부(3)에 전기적으로 접속되는 제어기(4), 그리고, 상기 제어기(4)의 제어에 의하여 신호를 발하는 경보장치(5) 등을 포함하여 이루어진다.As shown, the obstacle detection device under the vehicle body of the present embodiment includes a light emitting part 2 provided in the front lower part of the vehicle body 1, a light receiving part 3 installed facing the rear of the light emitting part 2, and And a controller 4 electrically connected to the light receiving unit 3, and an alarm device 5 for generating a signal under the control of the controller 4, and the like.
상기 발광부(2)는 전원공급으로 빛을 발산시키는 것이고, 상기 수광부(3)는 상기 발광부(2)로부터 받는 빛의 조도에 따라 전기적 성질 즉, 저항치가 변화되는 물질이 내장되어 있으며, 상기 제어기(4)는 이 수광부(3)와 전기적으로 접속되어 수광부(3)의 전기적 저항치의 변화를 감지하는 장치이다. 그리고, 상기 경보장치(5)는 상기 제어기(4)에 접속되며, 상기 제어기(4)의 제어에 의하여 경고신호를 발생시킨다.The light emitting unit 2 emits light by supplying power, and the light receiving unit 3 includes a material in which electrical properties, that is, resistance values, are changed according to illuminance of light received from the light emitting unit 2. The controller 4 is an apparatus that is electrically connected to the light receiving unit 3 to sense a change in the electrical resistance value of the light receiving unit 3. The alarm device 5 is connected to the controller 4 and generates a warning signal under the control of the controller 4.
이상과 같은 작용을 하는 구성들로 이루어진 본 실시예의 차체 하부 장애물 감지장치가 차체(1) 하부의 장애물을 감지하는 과정은 다음과 같이 이루어진다.The process of detecting an obstacle under the vehicle body 1 by the obstacle detecting device under the body of the present embodiment having the above-described components is performed as follows.
먼저, 차체의 전방 하부에 설치된 발광부(2)가 전원을 공급받아 빛을 발산시킨다. 이와 동시에 수광부(3)는 상기 발광부(2)로부터 빛을 받게 되고, 그 조도에 따라 전기적인 저항 특성이 변화된다.First, the light emitting unit 2 installed at the front lower portion of the vehicle body receives power and emits light. At the same time, the light receiving unit 3 receives light from the light emitting unit 2, and the electrical resistance characteristic changes according to its illuminance.
이 때, 상기 수광부(3)와 전기적으로 접속된 제어기(4)가 상기 수광부(3)의 저항치 변화를 감지하여, 발광부(2)와 수광부(3) 사이의 장애물 존재여부를 판단하며, 이 판단에 따라 경보장치(5)를 온/오프 시키게 된다. 즉, 발광부(2)에서 조사된 빛이 정상적인 조도로 수광부(3)에 입사되었다면, 장애물을 거치지 않고 입사된 것이 되며, 이를 차체의 하부에 장애물이 없음으로 인식하여 경보장치를 오프된 상태로 유지시킨다. 그런데, 만약, 수광부(3)에 입사된 발광부(2)의 빛의 조도가 정상치보다 낮다면, 장애물의 차단에 의하여 빛이 제대로 수광부(3)까지 도달치 못한 되며, 제어기(4)는 이를 차체의 하부에 장애물이 존재하고 있는 것으로 인식하여 경보장치(5)를 작동시켜 운전자에게 장애물의 존재를 알리게 된다.At this time, the controller 4 electrically connected to the light receiving unit 3 detects a change in the resistance value of the light receiving unit 3, and determines whether there is an obstacle between the light emitting unit 2 and the light receiving unit 3. According to the determination, the alarm device 5 is turned on / off. That is, if the light irradiated from the light emitting unit 2 is incident to the light receiving unit 3 with normal illuminance, the light is incident without passing through an obstacle, and the alarm device is turned off by recognizing that there is no obstacle under the vehicle body. Keep it. By the way, if the illuminance of the light of the light emitting unit 2 incident on the light receiving unit 3 is lower than the normal value, the light does not reach the light receiving unit 3 properly by blocking the obstacle, the controller 4 is Recognizing that an obstacle exists in the lower portion of the vehicle body to operate the alarm device 5 to inform the driver of the presence of the obstacle.
이상과 같이 본 실시예의 차체 하부 장애물 감지장치의 작동으로, 운전자는 굳이 내려다 보지 않아도 차체(1) 하부의 장애물을 인식하여 이에 대비할 수 있으므로, 운전자가 인식하지 못한 장애물과의 충돌로 인한 차체의 손상을 방지할 수 있다.As described above, the driver may recognize the obstacle under the vehicle body 1 and prepare for it by operating the lower obstacle detection device according to the present embodiment, so that the vehicle body may be damaged due to the collision with the obstacle not recognized by the driver. Can be prevented.
이상에서 상세히 설명한 바와 같은 본 고안에 의하면, 골목길 주행시나 주차시 차체 하부에 존재하는 경우, 운전자는 언제나 이를 인식하여 대비할 수 있게 되므로, 차체의 하부에 놓여진 장애물과의 충돌 특히, 인식하지 못한 장애물과의 충돌로 인하여 차체가 손상받게 되는 것을 미연에 방지할 수 있다.According to the present invention as described in detail above, when present in the lower part of the vehicle when driving or parking alleys, the driver can always recognize and prepare for this, collision with the obstacle placed on the lower part of the vehicle, in particular, It is possible to prevent the car body from being damaged by the collision.
한편, 본 고안은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 실용신안등록청구의 범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.On the other hand, the present invention is not limited to the above-described specific preferred embodiments, anyone of ordinary skill in the field to which the subject innovation belongs without departing from the gist of the subject innovation claimed in the utility model registration claims Modifications may be made.
