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 (socket jacket has been integrated on plastic feet) of flame-retardancy requirements usually by one, with the PCB of pin, Thermal Cutoffs (MTS), making leaf spring, the Aluminium Radiator composition that power transistor/MOSFET manages and is suitable.
Existing speed regulation module of fan mounting seat mechanism adopts structure as shown in Figure 1, its Thermal Cutoffs just can be equipped after needing frock to clamp, exist and the problems such as complicated are installed, lack detent mechanism in addition, cause assembling position fixing process twisting pin, thus damage is caused to its root, reduce product stability.
Summary of the invention
Object of the present invention is exactly provide a kind of to overcome defect that above-mentioned prior art exists to locate the mounting seat mechanism for speed regulation module of fan that is simple, high efficiency assembling.
Object of the present invention can be achieved through the following technical solutions:
A kind of mounting seat mechanism for speed regulation module of fan, it is characterized in that, comprise metal base, base, cylindrical device, elastic pressuring plate and PCB, described base is fixed on metal base, described cylindrical device loads in the groove of base, described elastic pressuring plate compresses cylindrical device, and make it be close on metal base, the pin of described cylindrical device is welded in PCB.
Described base is provided with the double L-shaped imitation-shaped groove for cylindrical device location.Efficiently solve cylindrical device directed difficult problem in installation process, eliminate workpiece rotary freedom, ensure that the positioning precision of subsequent processing, thus ensure that the stability of product, and increase substantially production efficiency, decrease the input of the accurate frock of assembling process, save project cost.
Described double L-shaped imitation-shaped groove mates with cylindrical device both sides L-type pin and arranges.
Described double L-shaped imitation-shaped groove is the groove of unsymmetric structure, carries out mistake proofing design to product.
Described base is provided with buckle and reference column, and described PCB is provided with the draw-in groove corresponding with buckle and the location hole corresponding with reference column.
Described base is the base be made by PBT material.PBT material possesses excellent dimensional stability, electrical insulating property, chemical proofing, thermal endurance.Its excellent dimensional stability determines that its accurate to dimension is high, and assembling product process stabilization, homogeneity are good, can design (utilizing part noumenon asymmetry to carry out mistake proofing design) by abundant application error-prevention on product; Its excellent electrical insulating property makes it possess the cylindrical electronic devices and components function of shielding protection, does not produce any interference to circuit design; Its chemical proofing makes product can work under rugged environment; Its high-fire resistance makes it on high temperature heat source-metal base, there is long-term work under high-power heater element environment.
Compared with prior art, the present invention has the following advantages:
