종래의 전자제어식 브레이크 시스템의 전기제어장치는 ECU하우징과 유압블럭이 볼트결합 되어있으므로 체결부재가 더 필요하고 공정이 복잡해지는 문제점이 있다.The electric control device of the conventional electronically controlled brake system requires a fastening member because the ECU housing and the hydraulic block are bolted, there is a problem that the process is complicated.

또한, ECU하우징과 유압블럭이 볼트결합 되어있으므로 별도의 씰링 공정을 추가해야 하거나, 이러한 공정이 없는 경우 씨일링이 잘 되지 못해서 ECU 하우징의 내부로 수분이 유입되어 성능에 결함이 생기는 문제점이 있다. In addition, since the ECU housing and the hydraulic block are bolted together, a separate sealing process needs to be added, or in the absence of such a process, sealing may not be performed, causing moisture to flow into the ECU housing, resulting in a problem in performance.

이하, 본 발명에 따른 하나의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명한다. 도 1은 본 발명의 실시예에 따른 전자제어식 브레이크 시스템용 전기제어장치의 전체구성을 나타내는 단면도이다. 도1을 참조하면, 전자제어식 브레이크 시스템의 유압블럭(1)에는 솔레노이드밸브(2)의 밸브조립체(2a)가 콤팩트하게 압입 설치되어 있다.Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. 1 is a cross-sectional view showing the overall configuration of an electric control apparatus for an electronically controlled brake system according to an embodiment of the present invention. Referring to Fig. 1, the valve assembly 2a of the solenoid valve 2 is press-fitted in a hydraulic block 1 of the electronically controlled brake system.

그리고 ECU(3)는 플라스틱재질로 사출 성형된 사각의 벽체를 가지며 유압블럭(1)에 마찰용접되어 결합되는 ECU하우징(31)과, 이러한 ECU하우징(31)의 하부의 별도 공간에 장착되는 PCB 회로기판(32)을 구비하며, ECU하우징(31)의 내부에는 솔레노이드 밸브(2)의 코일조립체(22)가 다수 개 장착된다.In addition, the ECU 3 has a square wall formed by injection molding of a plastic material, and is coupled to the hydraulic housing 1 by friction welding. The ECU 3 is mounted in a separate space below the ECU housing 31. A circuit board 32 is provided, and a plurality of coil assemblies 22 of the solenoid valve 2 are mounted inside the ECU housing 31.

코일조립체(22)는 원통상으로 코일(23)이 권선되며 회로기판(32)에 전기적으로 접속하기 위한 리드선(25)이 연장되게 마련된다. 또한, 하우징(31)과 유압블럭(1)을 결합하는 경우 코일 조립체(22)의 중심부에는 밸브 조립체(21)의 단부(슬리브)가 여유있게 삽입된다. 이에 따라 코일조립체(22)에 전류를 .인가하면, 여기에 전기장이 형성되고 이것에 의해 솔레노이드밸브(2)의 밸브조립체(21)가 개방 또는 폐쇄작동하게 된다. The coil assembly 22 has a cylindrical shape in which the coil 23 is wound, and a lead wire 25 for electrically connecting to the circuit board 32 is provided to extend. In addition, when the housing 31 and the hydraulic block 1 are coupled to each other, an end portion (sleeve) of the valve assembly 21 is inserted into the center of the coil assembly 22. Accordingly, when a current is applied to the coil assembly 22, an electric field is formed therein, which causes the valve assembly 21 of the solenoid valve 2 to open or close.

이 코일 조립체(22)는 ECU 하우징(31)의 바닥면에 형성된 지지부재(4)에 끼워져 고정되며, 여기에 유압블럭(1)에 장착된 밸브조립체(21)가 삽입 장착된다. The coil assembly 22 is fitted and fixed to the support member 4 formed on the bottom surface of the ECU housing 31, and the valve assembly 21 mounted on the hydraulic block 1 is inserted therein.

본 발명의 실시예에 따른 전자제어식 브레이크 시스템용 전기제어장치는 ECU 하우징(31)의 단부와 커버(33)를 마찰용접(Vibration Welding) 또는 융접에 의하여 마찰 접착을 시키게 된다. 따라서, 종래와 같이 별도로 씰링재를 사용하여 경화하여야 하는 공정이 불필요하게 된다.In the electric control apparatus for an electronically controlled brake system according to the embodiment of the present invention, the end of the ECU housing 31 and the cover 33 are subjected to friction bonding by friction welding or welding. Therefore, the process which needs to harden using a sealing material separately as conventionally is unnecessary.

도 2는 본 발명의 실시예에 따른 전자제어식 브레이크 시스템용 전기제어장치의 전체적인 구성을 보여주는 분해 사시도이다.Figure 2 is an exploded perspective view showing the overall configuration of the electric control device for an electronically controlled brake system according to an embodiment of the present invention.

ECU 하우징(31)은 복수의 원형 홀을 바닥면에 구비한다. 이는 보빈(24)을 내부에 수용할 수 있도록 하기 위한 것이다. 코일이 권선된 보빈(24)의 외부에는 원통형상의 상부케이스(도 1의 26참조)가 보빈(24)를 감싸며 장착되어 함께 ECU 하우징(31)의 홀에 수용된다. 이러한 보빈(24)의 상부에는 링 형상의 하부케이스(27)가 결합된다. 이렇게 보빈(24), 상부케이스(도 1의 26참조), 하부케이스(27)와 ECU 하우징(31)이 결합된 하우징 어셈블리(30)의 상부에는 PCB 회로기판(30)과 커버(33) 가 결합된다.The ECU housing 31 has a plurality of circular holes on the bottom surface. This is to allow the bobbin 24 to be accommodated therein. On the outside of the bobbin 24 wound around the coil, a cylindrical upper case (see 26 in FIG. 1) is mounted to surround the bobbin 24 and is accommodated together in the hole of the ECU housing 31. The upper case of the bobbin 24 is coupled to the ring-shaped lower case 27. Thus, the PCB circuit board 30 and the cover 33 are provided on the upper part of the housing assembly 30 in which the bobbin 24, the upper case (see 26 in FIG. 1), the lower case 27 and the ECU housing 31 are coupled. Combined.

PCB 회로기판(30)은 ECU 하우징(31)의 보빈(24)에 권선된 코일에 연결되면서 하부케이스(27)의 상측으로 돌출된 리드선(25)과 연결된다. 이러한 PCB 회로기판(30)의 상측에는 PCB 회로기판(30)을 보호하기 위한 커버(33)가 결합된다. The PCB circuit board 30 is connected to a coil 25 wound on the bobbin 24 of the ECU housing 31 and connected to a lead wire 25 protruding upward of the lower case 27. The cover 33 for protecting the PCB circuit board 30 is coupled to the upper side of the PCB circuit board 30.

커버(33)는 ECU 하우징(31)과 동일한 소재로 주로 플라스틱 사출물이다. 본 발명의 실시예에 따른 전자제어식 브레이크 시스템의 전기제어장치의 커버(33)와 ECU 하우징(31)의 커버(33)와 결합되는 단부에는 마찰용접(Vibration Welding)을 하기 위한 리브(미도시)가 형성된다. 리브의 형상은 아래에서 도 3과, 도4를 참조하여 설명하기로 한다. The cover 33 is the same material as the ECU housing 31 and is mainly a plastic injection molding. Ribs (not shown) for friction welding at end portions coupled with the cover 33 of the electric control apparatus of the electronic control brake system according to an embodiment of the present invention and the cover 33 of the ECU housing 31. Is formed. The shape of the ribs will be described below with reference to FIGS. 3 and 4.

도3은 도2에 표시된 원형부분을 확대하여 나타낸 확대단면도로서, 본 발명의 실시예에 따른 전자제어식 브레이크 시스템용 전기제어장치의 하우징과 하우징 커버의 부착구조를 나타낸 것이다.3 is an enlarged cross-sectional view showing an enlarged circular portion shown in FIG. 2, and shows an attachment structure of a housing and a housing cover of an electric control apparatus for an electronically controlled brake system according to an embodiment of the present invention.

ECU 하우징(31)의 단부에는 두 개의 리브(31a)가 형성된다. 이러한 리브(31a)는 ECU 하우징(31)과 동일한 재질로 일체로 형성되는 것이 바람직하며 주로 플라스틱 사출물로 구비될 것이다. 커버(33)는 판상의 부재로서 ECU 하우징(31)의 개구부를 덮을 수 있는 크기로서, ECU 하우징(31)과 같은 재질이면 마찰용접(융착)이 더욱 쉬울 것이다. 마찰용접은 용접할 물체의 접합면에 압력을 가한 상태로 서로 마찰시켜 발열에 의하여 접합부가 적당한 고온에 도달하였을 때 압접하는 방법으로서 융접이라고도 한다. 이러한 용접방법에 의하면 용접이 용이하고, 비교적 단시간(0.1~1 sec)에 이루어지며 용접면이 깨끗한 장점이 있다. 종래의 마찰용접은 주로 하나의 면이나 일면에 형성된 하나의 리브부를 마찰시켜 행해지는 것이 보편적이었다. Two ribs 31a are formed at the end of the ECU housing 31. The rib 31a is preferably formed integrally with the same material as the ECU housing 31 and may be mainly provided with a plastic injection molding. The cover 33 is a size that can cover the opening of the ECU housing 31 as a plate-like member. If the cover 33 is made of the same material as the ECU housing 31, friction welding (welding) will be easier. Friction welding is also referred to as fusion welding as a method of friction welding each other while applying pressure to the joint surface of the object to be welded, when the joint reaches an appropriate high temperature by heat generation. According to this welding method, the welding is easy, the relatively short time (0.1 ~ 1 sec) is made and the welding surface has the advantage of clean. Conventional friction welding is generally performed by rubbing one rib portion formed on one surface or one surface.

그러나, 이렇게 리브부나 마찰용접면이 1면이면 마찰용접에 의하여 접합되는 면도 일면이므로 용접된 물체에 충격이 가해지는 경우 용접된 부위가 약하면 융착이 해제될 위험이 있고, 용접이 취약하게 된 부위가 존재하는 경우에는 수분이 용접면 내부로 유입될 우려도 있다. However, if the rib portion or the friction welding surface is one surface, the shaved surface is joined by friction welding, so when the impact is applied to the welded object, if the welded portion is weak, there is a risk of fusion releasing, If present, there is a fear that water may flow into the weld surface.

따라서, 본 발명의 실시예에 따른 전자제어식 브레이크 시스템의 전기제어장치는 ECU 하우징(31)의 단부에 2겹의 리브를 형성하여 마찰용접 되었을 경우에도 충격에 강한 구조를 가지게 된다. 또한, 리브의 어느 한 부분의 용접이 취약한 경우라도 다른 한 개의 리브와의 용접면에 의해 씰링이 되므로 수분이 ECU 하우징(31)의 내부로 침투할 수 없어 ECU(전기제어장치)의 안전성 및 신뢰성을 보장할 수 있게 된다.Therefore, the electric control apparatus of the electronically controlled brake system according to the embodiment of the present invention has a structure resistant to impact even when friction welding is formed by forming two layers of ribs at the end of the ECU housing 31. In addition, even if the welding of any part of the rib is weak, the sealing surface is welded with the other rib, so that moisture cannot penetrate into the interior of the ECU housing 31, thereby ensuring safety and reliability of the ECU.

도 4는 도2에 표시된 원형부분을 확대하여 나타낸 확대단면도로서, 본 발명의 다른 실시예에 따른 전자제어식 브레이크 시스템용 전기제어장치의 하우징과 하우징 커버의 부착구조를 나타낸 것이다.Figure 4 is an enlarged cross-sectional view showing an enlarged circular portion shown in Figure 2, showing the attachment structure of the housing and the housing cover of the electric control device for an electronically controlled brake system according to another embodiment of the present invention.

본 발명의 다른 실시예에 따른 전자제어식 브레이크 시스템용 전기제어장치의 하우징 커버는 ECU 하우징(31)의 단부와 결합되는 커버 가장자리를 따라 두 겹의 리브(33a)가 형성된다. 이러한 리브(33a)는 도3의 리브(31a)와 마찬가지로 충격에 의해서도 용접면이 잘 떨어지지 않고 씰링이 완전하게 되어 수분이 ECU 하우징(31)의 내부로 침투할 수 없게 되는 효과가 있다. In the housing cover of the electric control apparatus for an electronically controlled brake system according to another embodiment of the present invention, two layers of ribs 33a are formed along a cover edge which is coupled to an end of the ECU housing 31. Like the ribs 31a of FIG. 3, the ribs 33a have an effect in that the welding surface is hardly dropped even by an impact and the sealing is completed, so that moisture cannot penetrate into the interior of the ECU housing 31.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 전자제어식 브레이크 시스템의 전기제어장치는 두 겹의 리브를 구비하므로 마찰용접 후에도 충격에 강하고 씰링이 완전하게 이루어져 수분이 침투하지 못하므로 제품의 신뢰성과 안전성을 향상시킬 수 있는 효과가 있다. As described in detail above, since the electric control device of the electronically controlled brake system according to the present invention has two layers of ribs, it is resistant to impact and complete sealing even after friction welding, so that moisture does not penetrate, thereby improving reliability and safety of the product. There is an effect that can be improved.

또한, ECU 하우징과 커버를 별도의 체결부재로 체결하지 않고 마찰용접을 함으로써 제품의 제조공정이 간단해지고 생산비가 절감되는 효과가 있다.In addition, by friction welding without fastening the ECU housing and the cover with a separate fastening member, the manufacturing process of the product is simplified and the production cost is reduced.
