Description
Technical field
The present invention relates to a kind of automobile air conditioner speed regulation module, especially relate to a kind of mechanism that is fixed and clamped for automobile air conditioner speed regulation module.
Background technology
Automobile Fan speed adjusting module is a battery-powered electronic building brick, according to the voltage at the signal change blower motor two ends that air-conditioner controller transmits, thus realizes the stepless speed regulation of blower fan; Speed adjusting module is divided from profile mounting structure and is mainly contained vertical structure and horizontal type structure type.
Existing speed regulation module of fan meets the plastic feet of flame-retardancy requirements usually by one, the PCB of band pin, Thermal Cutoffs, making leaf spring, the Aluminium Radiator composition that power transistor/MOSFET manages and suitable.
Wiring board in existing speed regulation module of fan adopts screw locking mode to fix usually, the mode that power heat generating component only keeps laminating or employing screw to add making leaf spring by soldering is simultaneously fixed, can cause the problems such as efficiency of assembling is low, cost is high, number of spare parts is many like this, not prison welding can cause the bad cause thermal damage caused of cooling surface contacts simultaneously.
Summary of the invention
Object of the present invention is exactly provide that a kind of packaging efficiency is high, cost is low, the mechanism that is fixed and clamped for automobile air conditioner speed regulation module of highly anti-fatigue intensity, good corrosion resistance to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of mechanism that is fixed and clamped for automobile air conditioner speed regulation module, it is characterized in that, comprise flat spring, wiring board and high-power heat generating component, pedestal and upper cover, described flat spring is loaded in upper cover stopper slot, wiring board and power heat generating component are put into pedestal simultaneously, the upper cover installing flat spring is loaded on pedestal, and pass through snap lock, under the effect of snap lock power, each contact place of flat spring and wiring board and high-power heat generating component produces deformation, thus compresses wiring board and power heat generating component.
Described flat spring is multiple spot cantilever design, realizes the compression of plurality of positions power heat generating member and wiring board.
Described flat spring comprises crossbeam, angle and multiple presser feet, described angle is fixedly connected with crossbeam respectively with multiple presser feet, described angle is connected with the location hole on wiring board and high-power heat generating component, and each presser feet crimps with each contact of wiring board and high-power heat generating component.
Described presser feet is provided with four.
Described flat spring is the spring that SUS301 stainless steel material is made.Prior art generally adopts phosphor-copper material to make; SUS301 is the steel grade of the easiest cold deformation strengthening, the intensity of steel, hardness can be made to improve by cold deformation processing, and retain enough to mould, toughness, higher load can be born, there is outstanding elevated temperature strength, fatigue resistance and corrosion resistance.
Flat spring application Sheet Metal Forming Technology realizes the processing of its complicated shape, and production efficiency is high and easy to operate, and parts quality is stable, interchangeability is good.
Described pedestal is provided with fixture block, is covered with the buckle corresponding with fixture block on described.
Compared with prior art, the present invention has the following advantages:
1) the present invention is by adopting flat spring structure, the screw fixing and locking scheme that contrast is conventional, has that efficiency of assembling is high, low cost and other advantages.Decrease amount of parts, reduce the manufacturing cost of part, decrease installation time, reduce assembly cost.
2) the present invention is by the multiple spot cantilever beam structure of flat spring, can compress, prevent not prison welding from causing the bad cause thermal damage caused of cooling surface contacts to the power heater members of many places.Avoid not the locking of screw scheme screw locking operation, to lock askew, sliding tooth etc. various bad, effectively improve the stability of product, reduce fraction defective.
