Background technology
Along with science and technology constantly progress, electronic equipment, towards high speed, Function Integration Mechanism and miniature trend, makes electronic building brick aggregation degree improve, and the heat that electronic equipment distributes is more, easy generation wild effect, and then affect the reliability of electronic equipment, therefore heat radiation becomes problem anxious to be resolved.
The application of the motor of current fan constantly expands, and for the equipment of special purpose, as the vehicles, fan, computer-related products etc., motor all must be used to make product operation; Generally in the environment of humidity, use the said goods; because the stator in motor, coil and circuit board are quite responsive for aqueous vapor; aqueous vapor can make motor internal cause the corrosion of motor because making moist and reduce useful life; severe patient can cause motor internal assembly electric short circuit to burn; make the disabler of motor and affect its running, therefore needing the mechanism of protection electronic building brick.
The personnel being familiar with this technology propose a solution, and are reduced in the gap between the rotor of fan and stator and the gap between fan frame and stator as far as possible, to make motor internal assembly more not moisture-sensitive, but the limitation that this kind of mode can be protected.
And another kind of method utilizes colloid to inject motor, although make colloid on motor external sheath can prevent aqueous vapor from invading, but this shortcoming is, because motor is complete coated by colloid, if when motor must carry out failure analysis, then motor entirety must be disassembled and can analyze, and the process disassembled easily destroys the aspect of motor script because of the coated of colloid, so a mode not easily carries out failure analysis and heavy industry.
The above, known have following shortcoming:
1. cannot available protecting circuit board;
2. circuit board is easy to wet environment and causes short circuit to burn;
3. not easily carry out failure analysis and heavy industry.
Therefore, how will solve problem and the disappearance of above-mentioned prior art, the inventor being this case studies the place, direction of improving with the anxious wish of relevant manufactures institute being engaged in the industry.
Summary of the invention
Therefore, for effectively solving the problem, main purpose of the present invention for provide a kind of can available protecting circuit board to avoid the waterproof structure of motor causing short circuit to burn in wet environment.
Secondary objective of the present invention, is that providing a kind of can reduce the waterproof structure of motor destroying motor script aspect when failure analysis.
For reaching above-mentioned purpose, the invention provides a kind of waterproof structure of motor, comprising: stator group, there is multiple silicon steel sheet and multiple coil; One housing, has an accommodation space and is formed with an open sides, is provided with the circuit board of the described coil of an electric connection in this accommodation space; And a cover body, be located at described open sides and this circuit board of cover cap.
The material of this housing is that macromolecular material or metal material are wherein arbitrary.
This cover body can be insulation colloid or seal cover wherein arbitrary.
This housing be combined with snap fit with the cover body that should be seal cover.
This housing with should be combined in gummed mode for the cover body of colloid of insulating.
This housing is formed with a sub-assembly in described accommodation space position, and this board sleeve is located on this sub-assembly.
This sub-assembly is more formed with a location division, and described circuit board is positioned on location division.
Have more an impeller, it has a wheel hub and multiple flabellum, and described flabellum is all sides being located on this wheel hub.
Whereby, make this housing and the Packed effect of this cover body tool, prevent aqueous vapor from invading, to reach protective circuit plate and internal electrical components, the situation avoiding circuit board to cause short circuit under the environment of humidity burning; In addition, if when motor is for carrying out failure analysis, described housing and cover body need only be carried out disassembling and can analyze and the described circuit board of unlikely damage and motor, avoid existing motor completely by colloid coated produce not easily-disassembled and the puzzlement of destructible circuit board.
