Abstract

The present disclosure relates to an electronic control apparatus for a vehicle, and the electronic control apparatus of the present disclosure includes: an electronic control element which includes an electronic control board which electrically controls each part of a vehicle, and a heating element which is positioned on a surface of the electronic control board; a cover and a base which accommodate the electronic control element; and a connector which is coupled to the electronic control element, in which an edge part where the cover and the base come into contact with each other is configured in a multi-step bent shape.

First claim

What is claimed is:

1. An electronic control apparatus for a vehicle, comprising:
an electronic control element which includes a printed circuit board (PCB) and a heating element installed on a surface of the PCB;
a cover and a base which accommodate the electronic control element; and
a connector which is coupled to the electronic control element,
wherein contact surfaces of the electronic control apparatus where the cover and the base come into contact with each other comprise a binding part having a groove portion and a protruding portion that are formed toward an outer edge of the cover and the base, respectively, and an edge part having a multi-step bent shape, the multi-step bent shape formed by bending an end portion of the binding part and an intermediate portion of the edge part,
wherein an end of the edge part having the multi-step bent shape extends away from the PCB and a multi-step of the multi-step bent shape continually steps down toward the outer edge of the cover and the base, such that a sealing member is inserted in a channel between the cover and the base that extends away from the PCB along with the multi-step bent shape toward the outer edge of the cover and the base,
wherein an edge of the PCB is inserted in the channel such that the PCB directly contacts and is sandwiched between the cover and the base.

2. The electronic control apparatus of claim 1 , wherein the sealing member is inserted between the protruding portion and the groove portion of the binding part.

3. The electronic control apparatus of claim 1 , wherein the edge part is extended from the binding part to the outer edge of the contact surfaces.

4. The electronic control apparatus of claim 3 , wherein the sealing member is included between the cover and the base at the binding part.

5. An electronic control apparatus for a vehicle, comprising:
an electronic control element which includes an electronic control board which electrically controls each part of a vehicle, and a heating element which is positioned on a surface of the electronic control board;
a cover and a base which accommodate the electronic control element; and
a connector which is coupled to the electronic control element,
wherein contact surfaces of the electronic control apparatus where the cover and the base come into contact with each other include a binding part which have a protruding portion and a groove portion that are formed at the cover and the base, respectively, and an edge part having a multi-step bent shape, the edge part is extended from the binding part to the outer edge of the contact surfaces, the multi-step bent shape formed by bending an end portion of the binding part and an intermediate portion of the edge part,
wherein an end of the edge part having the multi-step bent shape extends away from the PCB and a multi-step of the multi-step bent shape continually steps down toward the outer edge of the cover and the base, such that a sealing member is inserted in a channel between the cover and the base that extends away from the PCB along with the multi-step bent shape toward the outer edge of the cover and the base,
wherein an edge of the PCB is inserted in the channel such that the PCB directly contacts and is sandwiched between the cover and the base.

6. The electronic control apparatus of claim 5 , wherein the sealing member is included between the cover and the base at the binding part.
