Embodiment
Below in conjunction with specific embodiment, the present invention will be described in further detail.
A kind of ECU guard shields, its structure as depicted in figs. 1 and 2, including mutually equipped bottom 1 and upper lid 2, upper lid side
The lower junction surface that the upper junction surface and bottom edge that edge is formed are formed is bolted to connection, in the present invention, bottom and upper lid
It is made of magnesium alloy, magnesium alloy not only has certain intensity, and cost is low, is easy to process, and quality is good, heat conduction
Property it is good, the thermal conductivity that can strengthen ECU housings is made using magnesium alloy in bottom and upper lid, while reduces cost, mitigation ECU shells
Body weight.
Upper lid 2 forms the accommodating cavity of front opening after being fixedly connected with bottom 1, accommodating cavity includes the first anterior accommodating cavity
4 and second accommodating cavity 3 at rear portion, wherein the first accommodating cavity 4 is used to fix ECU plugs, the second accommodating cavity 3 is used to house ECU
Circuit board.
First accommodating cavity 4 is inverted trapezoidal structure, and trapezoidal angle is consistent with ECU plug angles, by before and after bottom every
The motion of the both sides of plate and trapezoidal chamber limitation ECU plugs all around, then the fortune up and down by upper lid limitation ECU plugs
Dynamic, such first accommodating cavity can be completely fixed ECU plugs.First accommodating cavity 4 is towards setting in the trapezoidal faces of front opening
There is seal groove 9, upper lid front end, which is provided with to match with seal groove, loads onto water-proof strip 6, plays sealing waterproof action.
Second accommodating cavity is formed by enclosing the lower water-proof strip 7 being located under bottom on junction surface, encloses to be formed by water-proof strip
The installation cavity of ECU circuit boards；4 fixed columns are provided with the inside of water-proof strip, as shown in figure 1, the motion for limiting circuit plate, prevents
Only shift.The upper junction surface of upper lid is correspondingly arranged on neck 8, and for clamping lower water-proof strip 7, water-proof strip and neck coordinate ECU
Circuit board protects, and realization is completely isolated with the external world, so as to prevent the liquid such as external water, oil from entering enclosure interior, waterproof
Effect is good, and fabulous protects internal ECU circuit boards.
It is even on the bottom face of bottom to be furnished with some fin 11, as shown in figure 3, increasing the heat friendship of housing and extraneous air
Change area；The position that bottom is in contact with circuit board is bonded with thermal grease layer.Caused heat leads in the circuit board course of work
Cross thermal grease layer to be quickly transferred on bottom, then radiated by the fin on bottom bottom face, served very well
Radiating effect.The setting of fin, the intensity of housing is also add, improve the compressive property of housing, it is practical.
The rectangular recess of the first accommodating cavity of connection is provided with the present invention, in the middle part of bottom, close to the square of bottom blind end
The blow vent 12 for installing one-way ventilating plug is provided with connected in star, the both sides of blow vent are provided with dividing plate, for preventing liquid
Body enters enclosure interior.
In the use of the present invention, first sealing ring or fluid sealant will be added in the seal groove on bottom, in the neck of upper lid
Fluid sealant is injected, last layer heat dissipating silicone grease is applied on the mounting plane of ECU circuit boards and bottom, then ECU circuit boards are placed in
In second accommodating cavity, plug is arranged in the second accommodating cavity and fixed, then close upper lid directly cover on bottom, bottom
In lower water-proof strip insertion neck, the upper water-proof strip that covers is pressed in the seal groove of ECU plugs, then screw is passed through into screwed hole 5
Upper lid and bottom lid is fixed, the accommodated inside chamber of such ECU shells is completely isolated with the external world, plays good waterproof sealing
Effect.
