Summary of the invention
Because above-mentioned problem, the object of the present invention is to provide and a kind ofly can utilize fan support structure, it has and supports and fixing a kind of supporting structure and preparation method thereof of sensing element.The invention provides a reliable sensing element supporting structure, between vehicle is advanced, more can avoid damaging, keep the detecting stability of sensing element because of the sensing element that vibrations cause being arranged at fan.
Edge is, for reaching above-mentioned purpose, the invention provides fan a kind of and sensing element and usefulness, and it comprises a transmission terminal, a fan frame, and a stator and has the rotor of flabellum.Transmission terminal is electrically connected with sensing element, the fan frame comprises a body, and it forms a wind inlet, and a supporting structure is directly yearned for from body and protruded into the zone that air communication is crossed in the wind inlet, and the part area of coating transmission terminal, stator then is arranged in the fan frame with the rotor with flabellum.
For reaching above-mentioned purpose, more provide a kind of making method of fan of and sensor and usefulness to comprise the following steps: to provide a mould according to the present invention; One transmission terminal is provided, and inserts in the mould; Carry out molding and forming, to form a fan frame with a supporting structure, supporting structure promptly coats the part area of transmission terminal at moulding while plastics; One sensing element is provided at last and sensing element and transmission terminal are linked by welding manner.
In sum, the invention provides and a kind ofly can on the fan housing, design a supporting structure, can support, fixing and coat transmission terminal, overcome the problem that existing fan often causes the sensing element displacement to be broken by flabellum because of vibrations.Moreover the transmission terminal that is coated also can avoid oxidation to cause distorted signals, has significantly promoted the reliability that fan is used, and guarantees simultaneously that also sensing element can provide correct signal to give application system, makes System Operation normal.In addition, the present invention is that the technology by molding and forming makes supporting structure coat transmission terminal simultaneously when moulding, can shorten the making time-histories.
For above-mentioned and other purposes of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and cooperate appended accompanying drawing, be described in detail below:
