Description

차량엔진룸의 온도조절을 위한 후드개폐장치{Hood open/close device for controlling the temperature of engine room of vehicle}Hood open / close device for controlling the temperature of engine room of vehicle}

본 발명은 차량엔진룸의 온도조절을 위한 후드개폐장치에 관한 것으로서, 더욱 구체적으로는 엔진룸의 온도를 측정하고 온도가 소정온도에 도달하면 후드를 열고 열기를 배출시켜 온도를 일정하게 유지함으로서 엔진의 냉각수와 오일, 트랜스미터의 오일을 냉각시키는 냉각시스템과 실내온도를 유지시키기 위한 냉방시스템의 효율을 증대시키고 컴팩트화를 달성할 수 있는 후드개폐장치에 관한 것이다.The present invention relates to a hood opening and closing device for controlling the temperature of a vehicle engine room, and more particularly, by measuring the temperature of the engine room and when the temperature reaches a predetermined temperature by opening the hood and exhausting heat to keep the temperature constant The present invention relates to a hood opening / closing device capable of increasing the efficiency of the cooling system for cooling the cooling water, the oil of the oil and the transmitter, and the cooling system for maintaining the room temperature and achieving compactness.

차량의 냉각/냉방시스템은 차량주행중에 엔진룸에서 발생되는 열을 일정하게 유지시켜주며 불필요한 열을 차량외부로 방출하는 기능을 수행하고 있다. 이러한 냉각/냉방시스템은 차량엔진룸 내부의 전면에 설치되어 있으며, 도 1을 참고하면, 차량의 전면에 형성된 라디에이터그릴(4)과 범퍼홀(6)을 통하여 외부로부터 공기를 유입시켜서 냉각/냉방기능을 수행한다.The cooling / cooling system of the vehicle keeps the heat generated in the engine room while driving the vehicle and discharges unnecessary heat to the outside of the vehicle. The cooling / cooling system is installed at the front of the inside of the vehicle engine room. Referring to FIG. 1, the cooling / cooling is performed by introducing air from the outside through the radiator grill 4 and the bumper hole 6 formed at the front of the vehicle. Perform the function.

도 2는 차량후드(2)의 하부에 위치하는 엔진룸의 개략적인 구조를 나타내는 중앙부 절단면도이다. 도시된 바와 같이, 고온의 열을 발생시키는 엔진 및 트랜스미션(10)의 전면에 방열기(8)가 설치되어 있다. 방열기(8)의 전면에는 라디에이터그릴(4)과 범퍼홀(6)이 형성되어 있어서 유입된 공기가 방열기(8)를 통과하면서 열을 방열기(8)의 외부로 발산시킨다.FIG. 2 is a cutaway view of the central portion showing the schematic structure of the engine compartment located under the vehicle hood 2. FIG. As shown, the radiator 8 is installed on the front of the engine and the transmission 10 that generates high temperature heat. The radiator grill 4 and the bumper hole 6 are formed on the front surface of the radiator 8 so that the introduced air dissipates heat to the outside of the radiator 8 while passing through the radiator 8.

방열기(8)를 통과한 공기는 방열기(8)로부터 발산되는 열기를 포함하기 때문에 온도가 상승하게 된다. 이에 따라서 엔진룸 내부의 공기온도는 약 100℃까지 상승하게 된다. 그런데, 상기와 같이 온도가 상승된 공기는 별도의 배출구가 없이 차량후드(2)의 표면을 통하여 열을 외부로 전달하도록 구성되어 있기 때문에 주행중인 차량의 엔진룸은 상당한 고온상태를 유지한다.Since the air passing through the radiator 8 includes heat radiated from the radiator 8, the temperature rises. Accordingly, the air temperature inside the engine room rises to about 100 ° C. However, since the air whose temperature is raised as described above is configured to transmit heat to the outside through the surface of the vehicle hood 2 without a separate discharge port, the engine room of the running vehicle maintains a considerable high temperature state.

이러한 고온상태에 의하여 엔진룸의 온도를 유지하기 위한 냉각/냉방시스템도 역시 효율이 떨어지게 되며, 차량의 엔진출력이 증가함에 따라서 더욱 더 큰 냉각/냉방시스템이 요구되고 있다. 이러한 요구는 차량의 원가 및 중량이 증대되는 한 요인이 된다. 따라서 더욱 효율적으로 냉방/냉각기능을 수행할 수 있으며 소형화시킬 수 있는 방열수단이 요구되고 있는 형편이다.Due to such a high temperature, the cooling / cooling system for maintaining the temperature of the engine room is also less efficient, and as the engine output of the vehicle increases, a larger cooling / cooling system is required. This demand is one factor that increases the cost and weight of the vehicle. Therefore, it is possible to perform the cooling / cooling function more efficiently, and the heat dissipation means that can be miniaturized is required.

본 발명은 상기한 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 엔진룸의 온도를 측정하고 온도가 소정온도에 도달하면 후드를 열고 열기를 배출시켜 온도를 일정하게 유지함으로서 엔진의 냉각수와 오일, 트랜스미터의 오일을 냉각시키는 냉각시스템과 실내온도를 유지시키기 위한 냉방시스템의 효율을 증대시키고 컴팩트화를 달성할 수 있는 후드개폐장치를 제공하는데 있다.The present invention is to solve the above problems, an object of the present invention is to measure the temperature of the engine room and when the temperature reaches a predetermined temperature by opening the hood and exhausting the heat by maintaining the temperature constant, the engine coolant and oil, It is to provide a hood opening and closing device that can increase the efficiency and compactness of the cooling system for cooling the oil of the transmitter and the cooling system for maintaining the room temperature.

상기 목적을 달성하기 위한 본 발명의 차량엔진룸의 온도조절을 위한 후드개폐장치는, 차량의 엔진룸의 온도를 검출하고 엔진룸의 온도를 조절하기 위한 장치에 있어서, 차량후드의 하부측에 부착되어 엔진룸의 온도를 측정하기 위한 온도센서와, 상기 온도센서로부터 입력되는 측정온도데이터를 참고하여 소정온도이상으로 엔진룸의 온도가 상승하면 제어신호를 출력하는 ECU와, 상기 ECU로부터 출력되는 제어신호에 따라서 작동되는 구동수단과, 상기 구동수단에 의하여 작동되어 차량후드를 소정높이만큼 이동시키거나 원위치시키는 링크수단을 포함하는 것을 특징으로 한다.Hood opening and closing device for temperature control of the vehicle engine room of the present invention for achieving the above object, in the device for detecting the temperature of the engine room of the vehicle and adjusting the temperature of the engine room, attached to the lower side of the vehicle hood A temperature sensor for measuring the temperature of the engine room, an ECU which outputs a control signal when the temperature of the engine room rises above a predetermined temperature by referring to the measured temperature data input from the temperature sensor, and the control output from the ECU. And driving means operated according to the signal, and linking means operated by the driving means to move or reposition the vehicle hood by a predetermined height.

이하 첨부된 도면을 참고하여 본 발명의 차량엔진룸의 온도조절을 위한 후드개폐장치를 상세히 설명하면 다음과 같다.Hereinafter, a hood opening and closing device for temperature control of a vehicle engine room of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 엔진룸의 상부측에 위치하며 엔진룸을 외부와 차단하는 차량후드를 소정온도조건에 따라서 개폐시킴으로서 엔진룸의 온도를 일정수준으로 유지하여 냉방/냉각시스템의 성능을 향상시키기 위한 것이다. 본 발명에 의하면 종래 엔진용량의 증가에도 불구하고 냉각/냉방시스템을 소형화시킬 수 있어서 원가 및 중량을 절감할 수 있다.The present invention is to improve the performance of the cooling / cooling system by maintaining the temperature of the engine room to a certain level by opening and closing the vehicle hood that blocks the engine room from the outside in accordance with a predetermined temperature conditions located on the upper side of the engine room. According to the present invention, despite the increase in the conventional engine capacity, the cooling / cooling system can be miniaturized, thereby reducing the cost and weight.

도 3은 본 발명의 후드개폐장치가 설치된 엔진룸의 중앙부 절단면도이다. 도시된 바와 같이 차량후드(2)의 하부측에 엔진룸의 실내온도를 측정하기 위한 온도센서(12)가 부착된다. 상기 온도센서(12)는 방열기(8)의 후단에 위치하며 엔진룸으로 유입된 후에 방열기(8)를 통과하면서 승온된 공기의 온도를 측정한다. 온도센서(12)는 측정된 온도데이터를 ECU(14)로 입력시킨다. 상기 온도센서(12)는 서모스태트와 같은 온도측정센서를 이용하여 구성할 수 있다.3 is a cross-sectional view of the center of the engine room in which the hood opening and closing device of the present invention is installed. As shown, a temperature sensor 12 is attached to the lower side of the vehicle hood 2 for measuring the room temperature of the engine compartment. The temperature sensor 12 is located at the rear end of the radiator 8 and after entering the engine room, passes through the radiator 8 and measures the temperature of the heated air. The temperature sensor 12 inputs the measured temperature data to the ECU 14. The temperature sensor 12 may be configured using a temperature measuring sensor such as a thermostat.

ECU(14)는 온도센서(12)로부터 입력되는 온도데이터를 이용하여 미리 입력된 설정온도와 비교한다. 설정온도는 엔진룸에서 최적의 상태로 냉각/냉방을 수행하는데 적합한 온도로서 사용자/제조자에 의하여 입력될 수 있으며, 차종에 따라서 서로 다른 값을 갖는다.The ECU 14 uses the temperature data input from the temperature sensor 12 to compare with the preset temperature input. The set temperature may be input by the user / manufacturer as a temperature suitable for performing cooling / cooling in an optimal state in the engine room, and has a different value depending on the vehicle model.

상기 ECU(14)는 종래 차량에 장착되어 있는 ECU를 이용하거나 또는 별도의 ECU를 장착하여 사용하는 것이 가능하다. 후자의 경우와 같이 별도의 ECU를 이용하는 경우에는 차량의 전체 작동을 제어하는 ECU와의 데이터 송수신기능을 추가하여 차량의 비주행시에는 작동되지 않도록 구성할 수 있다.The ECU 14 may be used by using an ECU mounted on a conventional vehicle or by mounting a separate ECU. As in the latter case, when a separate ECU is used, a data transmission / reception function with an ECU that controls the overall operation of the vehicle may be added to prevent the vehicle from operating when the vehicle is not driven.

ECU(14)에서는 입력되는 측정온도데이터를 미리 입력된 설정온도와 비교하고, 설정온도보다 측정온도가 높으면 엔진룸의 온도를 하강시키기 위한 제어신호를 출력한다. 출력되는 제어신호는 구동수단(16)에 입력된다.The ECU 14 compares the input measurement temperature data with a preset input temperature, and outputs a control signal for lowering the temperature of the engine room when the measurement temperature is higher than the set temperature. The output control signal is input to the drive means 16.

상기 구동수단(16)은 ECU(14)로부터 출력되는 제어신호에 따라서 작동되어 차량후드(2)를 개폐시키는데 필요한 동력을 제공하기 위한 것이다. 구동수단(16)의 일례를 들면 상기 ECU(14)로부터 입력되는 제어신호를 해석하는 콘트롤러(16a)와 상기 콘트롤러(16a)로부터의 작동신호에 따라서 작동되는 액츄에이터(16b)를 포함하고 있다. 또다른 구동수단으로서 솔레노이드밸브나 실린더를 이용할 수 있다.The driving means 16 is operated according to a control signal output from the ECU 14 to provide the power necessary to open and close the vehicle hood 2. An example of the drive means 16 includes a controller 16a for interpreting a control signal input from the ECU 14 and an actuator 16b operated according to an operation signal from the controller 16a. As another driving means, a solenoid valve or a cylinder can be used.

상기 콘트롤러(16a)는 ECU(14)로부터 제어신호가 입력되면 입력된 신호에 따라서 액츄에이터(16b)를 작동시키는 신호를 출력하고, 액츄에이터(16b)는 이 신호에 따라서 로드를 작동시킨다. 실제로 액츄에이터(16b)는 직선운동에 의한 회전동력을 제공한다. 액츄에이터(16b)는 종래 잘 알려져 있으므로 상세한 설명은 생략한다.When the control signal is input from the ECU 14, the controller 16a outputs a signal for operating the actuator 16b according to the input signal, and the actuator 16b operates a load according to this signal. In fact, the actuator 16b provides rotational power by linear motion. Since the actuator 16b is well known in the art, detailed description thereof will be omitted.

액츄에이터(16)에 의한 직선운동은 링크수단(18)에 전달된다. 상기 링크수단(18)은 구동수단(16)으로부터 전달된 직선운동을 회전운동으로 전환시켜서 차량후드(2)를 개방시키거나 또는 폐쇄시키기 위한 것이다.The linear motion by the actuator 16 is transmitted to the link means 18. The link means 18 is for opening or closing the vehicle hood 2 by converting the linear motion transmitted from the drive means 16 into a rotational motion.

도 4에는 링크수단(18)의 일례가 표시되어 있다. 링크수단(18)은 세 개의 링크부재(18a,18b,18c)로 구성되어 있으며, 각각의 부재들은 제1고정축(18d)과, 제2고정축(18e)에 의하여 상호회동가능하게 연결된다.An example of the link means 18 is shown in FIG. The link means 18 is composed of three link members 18a, 18b, and 18c, each of which is rotatably connected by a first fixed shaft 18d and a second fixed shaft 18e. .

최하부측에는 액츄에이터(16b)로부터 연장되는 로드와 연결되는링크부재(18a)가 위치하고, 제1고정축(18d)에 의하여 링크부재(18b)와 회동가능하게 연결되며, 링크부재(18b)는 제2고정축(18e)에 의하여 링크부재(18c)와 회동가능하게 고정된다.Link member 18a which is connected to the rod extended from the actuator 16b is located in the lowermost side, is rotatably connected with the link member 18b by the 1st fixed shaft 18d, and the link member 18b is the 2nd It is rotatably fixed to the link member 18c by the fixed shaft 18e.

링크부재(18a)는 액츄에이터(16b)의 로드의 직선운동에 따라서 회전하게 되며, 이에 따라서 제1고정축(18d)을 중심으로 링크부재(18b)가 회전하면서 제2고정축(18e)을 중심으로 링크부재(18c)가 회동한다. 이 회동에 의하여 차량후드(2)가 상부측으로 이동되면서 양측면에 공간이 형성된다. 상부측으로의 이동거리는 링크수단(18)의 링크부재(18a,18b,18c)의 회동정도를 조정하여 결정할 수 있다.The link member 18a is rotated according to the linear motion of the rod of the actuator 16b. As a result, the link member 18b is rotated about the first fixed shaft 18d, and the link member 18a is rotated about the second fixed shaft 18e. The link member 18c rotates. By this rotation, the vehicle hood 2 is moved to the upper side, and spaces are formed on both sides. The movement distance to the upper side can be determined by adjusting the degree of rotation of the link members 18a, 18b, 18c of the link means 18.

도면을 다시 참고하면 액츄에이터(16b)의 로드가 수축되면 차량후드(2)를 개방시키고, 로드가 연장되면 차량후드(2)를 폐쇄시키게 된다. 차량후드(10)의 개방은 엔진룸의 내부에 있는 고온의 공기를 외부로 배출할 수 있도록 충분한 공간을 확보하는 것이 중요하지만, 주행중에 너무 공간이 많이 개방되면 소음이 발생할 가능성이 존재하므로 약 10mm 정도로 개방시키는 것이 바람직하다.Referring to the drawings again, when the rod of the actuator 16b is contracted, the vehicle hood 2 is opened, and when the rod is extended, the vehicle hood 2 is closed. The opening of the vehicle hood 10 is important to secure enough space to discharge the hot air inside the engine room to the outside, but if the space is too much open while driving, there is a possibility of noise generated about 10mm It is preferable to open to the extent.

또한 10mm 정도 개방시켰을 때, 주행중의 소음발생을 방지하기 위하여 상부연장부(18c)의 단부는 차량후드(2)의 단부를 수납할 수 있도록 단턱을 형성할 수 있다. 단턱은 차량후드(2)를 열어주는 경우에는 열림상태를 방해하지 않고, 본 발명의 후두개폐장치가 작동되는 경우에 차량후드(2)를 받치는 역할을 한다. 또한 도면에서는 차량후드(2)의 일측에만 도시된 것으로 설명되었지만, 차량후드(2)의 양측면에 설치하여 동시에 작동되도록 구성한다.In addition, when opened about 10mm, in order to prevent the generation of noise while driving, the end of the upper extension (18c) can be formed stepped to accommodate the end of the vehicle hood (2). The stepped foot does not interfere with the open state when the vehicle hood 2 is opened, and serves to support the vehicle hood 2 when the laryngeal opening and closing device of the present invention is operated. In addition, in the drawings, but is described as shown only on one side of the vehicle hood 2, is installed on both sides of the vehicle hood (2) is configured to operate simultaneously.

도 5에는 상기와 같은 구성을 가진 본 발명의 차량엔진룸의 온도조절을 위한후드개폐장치의 블럭배선도가 도시되어 있다. 도시된 바와 같이, 차량후드의 하부측에 부착되어서 엔진룸의 온도를 측정하기 위한 온도센서(12)와, 상기 온도센서(12)로부터 입력되는 측정온도데이터를 참고하여 소정온도이상으로 온도가 상승하면 제어신호를 출력하는 ECU(14)와, 상기 ECU(14)로부터 출력되는 제어신호에 따라서 작동되는 구동수단(16)과, 상기 구동수단(16)에 의하여 작동되어 차량후드(2)를 소정높이만큼 이동시키거나 원위치시키는 링크수단(18)을 포함하고 있다. 여기에서 구동수단(16)은 콘트롤러(16a)와 액츄에이터(16b)를 사용하고 있다.5 is a block diagram of a hood opening and closing device for temperature control of a vehicle engine room of the present invention having the configuration as described above. As shown, the temperature is increased above a predetermined temperature by referring to a temperature sensor 12 attached to the lower side of the vehicle hood to measure the temperature of the engine compartment and measurement temperature data input from the temperature sensor 12. ECU 14 which outputs a control signal at the lower surface, driving means 16 operated according to the control signal output from ECU 14, and actuated by the driving means 16 to define the vehicle hood 2; Link means 18 for moving or repositioning by height is included. Here, the drive means 16 uses the controller 16a and the actuator 16b.

그러나 상기 구동수단(16)은 더욱 간단하게 솔레노이드밸브(미도시됨)를 이용하여 구성할 수 있다. 여기에서 솔레노이드는 콘트롤러와 액츄에이터의 역할을 동시에 수행할 수있으며, 작동신호는 ECU(14)로부터 직접 받을 수 있다. ECU(14)로부터 신호가 입력되면, 솔레노이드밸브는 자력을 생성하여 내부에 설치된 로드가 작동되어서 결과적으로 링크수단(18)을 작동시킬 수 있다.However, the drive means 16 can be configured more simply using a solenoid valve (not shown). Here, the solenoid can act as a controller and an actuator at the same time, the operation signal can be directly received from the ECU (14). When a signal is input from the ECU 14, the solenoid valve generates magnetic force so that a rod installed therein can be activated, and as a result, the link means 18 can be operated.

또한 ECU(14)로부터의 신호입력이 중단되면 솔레노이드밸브의 로드는 원위치로 복귀하며 이에 따라서 링크수단(18)도 역시 원위치로 복귀하게 되고 이에 따라서 차량후드(2)도 폐쇄상태가 되는 것이다. 또는 승하강 실린더를 이용하여 직접 차량후드(2)를 개폐시키는 것도 가능함은 명백하다.In addition, when the signal input from the ECU 14 is stopped, the rod of the solenoid valve returns to its original position, and thus the link means 18 also returns to its original position, and thus the vehicle hood 2 is also closed. Or it is apparent that the vehicle hood 2 can be opened and closed directly by using a lifting cylinder.

차량후드(2)의 개방/폐쇄상태를 결정하기 위한 온도조건은 차량에 따라서 변경될 수 있다. 즉 온도조건은 소형차량, 중형차량, 대형차량, 또는 각 차량에 설치된 냉방/냉각시스템의 효율에 따라서 변경될 수 있으며 이러한 변경은 모두 본 발명의 범위에 속한다 할 것이다.The temperature conditions for determining the open / closed state of the vehicle hood 2 can be changed depending on the vehicle. That is, the temperature condition may be changed according to the efficiency of the small vehicle, the medium vehicle, the large vehicle, or the cooling / cooling system installed in each vehicle, and all such changes will belong to the scope of the present invention.

더욱이 본 발명에 의한 차량엔진룸의 온도조절을 위한 후드개폐장치가 채택되면 라디에이터그릴 또는 범퍼홀을 통하여 상대적으로 적은 공기가 유입되어도 충분한 냉각/냉방효과를 거둘 수 있기 때문에 라디에이터그릴이나 범퍼홀의 형태를 더욱 미관을 고려하여 디자인할 수 있는 이점을 가진다.Furthermore, if the hood opening and closing device for temperature control of the vehicle engine room according to the present invention is adopted, the radiator grill or bumper hole may be formed because a sufficient cooling / cooling effect may be obtained even when relatively little air is introduced through the radiator grill or bumper hole. It has an advantage that can be designed with more aesthetic considerations.
