Electronic control unit for vehicle
View Patent ↗The present invention relates to an electronic control unit for a vehicle. The electronic control unit for a vehicle can improve waterproof efficiency of a space between an upper case and a lower case in order to prevent damage to internal components, thereby improving steering stability.
1. An electronic control unit for a vehicle, comprising:
a protruding coupling part protruding from one side of a coupling part where an upper case and a lower case are coupled to each other while contacting each other and formed of a resilient material; and
a waterproofing coupling part inserted into and coupled to a coupling recess formed at an opposite side of the coupling part and having a protruding coupling part insertion recess such that the protruding coupling part is inserted into and fixed to the protruding coupling part insertion recess, wherein wings are formed at upper ends of the waterproofing coupling part and extend to both sides.
2. The electronic control unit of claim 1 , wherein an expanded space for expanding a space between facing inner surfaces of the protruding coupling part insertion recess of the waterproofing coupling part and the protruding coupling part is formed at an opposite side of an opening of the protruding coupling part insertion recess of the waterproofing coupling part.
3. The electronic control unit of claim 2 , wherein a stress dispersing recess for dispersing a stress concentrated on the bottom surface of the expanded space when the protruding coupling part is inserted is formed on the bottom surface of the expanded space.
4. The electronic control unit of claim 1 , wherein a plurality of bosses are formed at a lower portion of the protruding coupling part to be spaced apart from each other such that gas in a space between the protruding coupling part and the waterproofing coupling part is exhausted to the outside when the protruding coupling part and the waterproofing coupling part are coupled to each other.
5. The electronic control unit of claim 4 , wherein the bosses are formed at opposite sides of a lower portion of the protruding coupling part.
6. The electronic control unit of claim 5 , wherein the boss formed at one side of the lower portion of the protruding coupling part and the boss formed at an opposite side of the lower portion of the protruding coupling part are disposed in a staggered configuration.
7. The electronic control unit of claim 1 , wherein the protruding coupling part has a wedge shape of which a width decreases as it goes towards an end of the protruding coupling part inserted into the protruding coupling part insertion recess.
8. The electronic control unit of claim 1 , wherein a curved ball portion protruding from an end of the protruding coupling part, which is inserted into the protruding insertion recess, to the outside is provided in the protruding coupling part.
9. An electronic control unit for a vehicle, comprising:
a protruding coupling part protruding from one side of a coupling part where an upper case and a lower case are coupled to each other while contacting each other and formed of a resilient material; and
a waterproofing coupling part inserted into and coupled to a coupling recess formed at an opposite side of the coupling part and having a protruding coupling part insertion recess such that the protruding coupling part is inserted into and fixed to the protruding coupling part insertion recess;
wherein a plurality of bosses are formed at a lower portion of the protruding coupling part to be spaced apart from each other such that gas in a space between the protruding coupling part and the waterproofing coupling part is exhausted to the outside when the protruding coupling part and the waterproofing coupling part are coupled to each other, and
wherein the bosses are formed at opposite sides of a lower portion of the protruding coupling part.
10. The electronic control unit of claim 9 , wherein an expanded space for expanding a space between facing inner surfaces of the protruding coupling part insertion recess of the waterproofing coupling part and the protruding coupling part is formed at an opposite side of an opening of the protruding coupling part insertion recess of the waterproofing coupling part.
11. The electronic control unit of claim 10 , wherein a stress dispersing recess for dispersing a stress concentrated on the bottom surface of the expanded space when the protruding coupling part is inserted is formed on the bottom surface of the expanded space.
12. The electronic control unit of claim 9 , wherein the boss formed at one side of the lower portion of the protruding coupling part and the boss formed at an opposite side of the lower portion of the protruding coupling part are disposed in a staggered configuration.
13. The electronic control unit of claim 9 , wherein the protruding coupling part has a wedge shape of which a width decreases as it goes towards an end of the protruding coupling part inserted into the protruding coupling part insertion recess.
14. The electronic control unit of claim 9 , wherein a curved ball portion protruding from an end of the protruding coupling part, which is inserted into the protruding insertion recess, to the outside is provided in the protruding coupling part.
