Specific implementation mode
Below in conjunction with specific embodiment, the present invention will be further described in detail.
A kind of ECU guard shields, structure is as depicted in figs. 1 and 2, including mutually equipped bottom cover 1 and upper cover 2, upper cover side
Edge formed upper joint portion and bottom cover edge formed lower joint portion be bolted to connection, in the utility model, bottom cover and
Upper cover is all made of magnesium alloy and is made, and magnesium alloy not only has certain intensity, but also at low cost, easy to process, high-quality,
Thermal conductivity is good, and bottom cover and upper cover are all made of magnesium alloy and the thermal conductivity that can reinforce ECU shells are made, while reducing cost, mitigates
ECU case weights.
Upper cover 2 forms the accommodating cavity of front opening after being fixedly connected with bottom cover 1, accommodating cavity includes the first accommodating cavity of front
4 and rear portion the second accommodating cavity 3, wherein the first accommodating cavity 4, for fixing ECU plugs, the second accommodating cavity 3 is for housing ECU
Circuit board.
First accommodating cavity 4 be inverted trapezoidal structure, trapezoidal angle is consistent with ECU plug angles, by before and after bottom cover every
The both sides of plate and trapezoidal chamber limit the movement of ECU plugs all around, then the fortune up and down of ECU plugs is limited by upper cover
Dynamic, such first accommodating cavity can be completely fixed ECU plugs.First accommodating cavity 4 is towards being arranged in the trapezoidal faces of front opening
