The principle of work of light modulation motor actr is: receive electric signal, by motor, drivings device such as worm and gear and sliding shoe are converted into the fore and aft motion of ball stud.Ball stud promotes mirror motion, thereby realizes the adjusting of light level attitude.
In addition, generally also have a manual regulating device, be used for adjusting the initial position of ball stud, in order to proofread and correct the level attitude of light in light modulation motor actr outside.
The mode of operation of light modulation motor actr has two kinds of situations: manual regulation and automatically regulating.Manual regulation is meant installs slide switch on car panel, regulate the level attitude of light by the diverse location of manual regulation switch.Automatically regulating is meant by sensor and sends conditioning signal to printing board PCB, comes the level attitude of automatically regulating light by drivings device such as motor and worm and gears.
The light modulation motor actr of prior art is widely used on some high-grade cars, but in the prior art, the shell fragment spring is installed on the loam cake PIN pin in the actr, weld contact disk on the printed circuit board (PCB), come contact disk on holddown spring and the printed circuit board (PCB) by the bayonet fitting between loam cake and the pedestal, thereby finish the transmission of signal.The shortcoming of doing like this is, if occur deviation in the fitting process, causes bad contact or instability easily, causes the signal erroneous judgement, thereby can't realize regulatory function effectively.
Therefore, demand a kind of light modulation motor actr that can overcome above-mentioned defective urgently.
Summary of the invention
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of light modulation motor actr of avoiding bad contact.
To achieve these goals, the utility model provides a kind of light modulation motor actr, it comprises pedestal, cover assembly and printed circuit board (PCB), be provided with electric system in the described pedestal, described cover assembly is injected with metal PIN pin, described printed circuit board (PCB) is arranged between described pedestal and the described cover assembly, and is electrically connected mutually with described electric system
It is characterized in that, described printed circuit board (PCB) is provided with connecting bore, described connection hole is set with connect spring, and described metal PIN cushion is connected to described connect spring, and produces by described connect spring between described metal PIN pin and the described printed circuit board (PCB) and be electrically connected.
In the utility model, described connect spring preferably is positioned at described base interior, after described metal PIN pin passes described connecting bore, is plugged in described connect spring.
In the utility model, described cover assembly also comprises loam cake, helical wheel and control apparatus, described loam cake has hold down groove and assembly opening, and described control apparatus is placed in the described hold down groove, and described helical wheel is installed in the described assembly opening removably, described helical wheel and described control apparatus have the gear teeth that cooperatively interact, and, having the engaging position in the described hold down groove by described gearteeth, described control apparatus has cooresponding engagement section.
According to above-mentioned setting, light modulation motor actr provided by the utility model, in cover assembly and pedestal fitting process, metal PIN pin can directly insert in the connect spring inner chamber, has avoided bad contact or unsettled phenomenon.Electric signal directly is transferred on the printed circuit board (PCB) by metal PIN pin and connect spring, thereby controls the rotation of electric system, and then realizes the fore and aft motion of ball stud, finishes the level attitude regulatory function of light.
