Description

The master cock of automatically controlled back mirror

The utility model relates to a kind of vehicle body fittings master cock, particularly be installed on the handle in the driver's cab of sedan side doors such as red flag, Audi, be used for controlling turning to of motor in the commutator of automatically controlled back mirror, make commutator do the upper and lower, left and right motion, thereby drive the visor that the visor plate is housed by commutator, swing within the specific limits, reach and adjust back mirror angle, the master cock of the automatically controlled back mirror of broadening one's vision.

Most back mirrors used in the existing domestically-made vehicle are still by chaufeur control, operates very inconveniently, and the while also influences traffic safety.

Also mention installation and control switch in operator's compartment in the patent No. 96231693.8 " visitor, lorry driven rearview mirrors ", but concrete scheme is not arranged.

The purpose of this utility model be to provide a kind of simple in structure, volume is little, the master cock of operation, automatically controlled back mirror easy to use, motor steering in left and right two back mirrors of may command in the commutator, reach by commutator and drive the visor swing that the visor plate is housed, the purpose of regulate the visor angle, broadening one's vision.

The utility model is achieved in that the master cock of automatically controlled back mirror is by the band control key, the housing of button and the printed circuit board (PCB) of being with pin, bonnet connects into whole the composition, be fixed on the contact frame and also connect on the housing by contact, the chute of contact frame lower end is buckled in moving contact that the spring limit constitutes and the static contact on the printed circuit board (PCB) and often connects and composes and open, normally closed contact, again by often opening, normally closed contact is formed contact bank, one termination power negative pole of the open contact in every group, the positive level of one termination power of normally closed contact, and often open, the in addition end of normally closed contact connects into pin position independently and is connected with motor two ends in the commutator in the automatically controlled back mirror respectively.

Following structure accompanying drawing is further described embodiment of the present utility model:

The upper surface of housing (3) is divided into the groove of upper and lower two band through holes, knock hole and locating notch are arranged on the sidewall, also has positioning rib on the side inwall, inner chamber is divided into upper and lower two controls again, the framework that one square band through hole, screw are arranged in the middle of the cavity of resorption, the small frame that band through hole in parallel is arranged on three sides of framework is with spring (9) on the projection of small frame bottom, puts into columniform push rod (11) in the through hole.

Rubber pad (13) has the square of square hole, four jiaos of blind holes that the protrusion that cooperates with push rod (11) is arranged for the centre.

Contact (7) is fixed on the contact frame (8), and the both sides that contact frame (8) utilizes the chute of its lower end to be buckled in the spring (9) on the small frame constitute moving contact (10), and push rod (11) is aimed at the dip plane of contact frame (8) lower end one side.

Two contacts (7) and spring (9) are fixed on contact frame (8) ' go up constitute moving contact (10) ', embed in the epicoele of inner chamber with the epicoele wall on the steel ball cunning join.

There is pin position pin (4) at printed circuit board (PCB) (12) back side, and periphery has locating notch and projection, and there is through hole the centre.And in addition face has printed wire and static contact and pin position weld nugget, by static contact and moving contact often connect and compose open, normally closed contact, on the printed circuit board (PCB) (12) by by the K that often opens, normally closed contact is formed ₁, K ₂, K ₃Contact bank, one termination power negative pole, 2 pin of the open contact in every group, anodal 1 pin of one termination power of normally closed contact, and often open, the end in addition of normally closed contact and 6 pin that pin is received at the motor two ends in the commutator in the back mirror respectively, on 4 (5) pin, 7 (8) pin.

On the one side of bonnet (5) pin cover and through hole are arranged, periphery has locating notch, wire hole and buckle.

Control knob (1) is inserted in the through hole of upper groove of housing (3) upper surface with inner chamber in moving contact (10) ' be connected in aggregates, earlier rubber pad (13) is put into the low groove of housing (3) upper surface, cover button (2) again, make its 4 long buttons with the back side, the through hole that passes on rubber pad (13) and the housing (3) is buckled in the low groove of housing (3).Again printed circuit board (PCB) (12) is put into housing (3), be close to moving contact (10), (10) on it ', and cooperate with housing (3) with the locating notch on it, projection, covering bonnet (5) at last cooperates with housing (3), with screw bonnet (5), printed circuit board (PCB) (12), housing (3) are connected into the single-piece master cock, be installed on the handle in the car side door.

During use,, just control key (1) is moved to the left, pulls out the L place, both driven connected moving contact (10) if will adjust the back mirror on the left side ', make moving contact (10) ' to moving to left contact with static contact on the printed circuit board (PCB) (12).At this moment K ₂, K ₃Connect with 4,7 pin positions respectively, if press the upper position place of button (2), at this moment K again ₁Action, promptly moving contact (10) is gone up K at printed circuit board (PCB) (12) ₁Translation on the static contact at place makes connected open contact closure, and normally closed contact is opened, and this moment, to connect 2 pin positions be negative pole in 6 pin positions.Because of K ₂, K ₃Not action, 4,7 pin positions connect 1 pin position for anodal.This moment, controlled two motor D 1, D2 did inside running simultaneously, drive the visor plate that visor is housed with the commutator bonded assembly do upward to swing.Release button (2) moving contact is got back to the home position under spring (9) power effect.

If the lower position place that presses button (2), then K ₂, K ₃Action, open contact closure, normally closed contact are opened, and this moment, to connect 2 pin positions be negative pole in 4.7 pin positions, because of K ₁Not action, 6 pin positions are anodal by 1 pin position, at this moment two motor D ₁, D ₂Do outside running simultaneously, drive the swing that the visor plate that visor is housed with the commutator bonded assembly is made downward direction.

If press the place, the left side of button (2), then K ₁, K ₂Action, open contact closure, normally closed contact are opened, and it is negative pole that 4,6 pin positions connect 2 pin positions, because of K ₃Not action, 7 pin positions connect 1 pin position for anodal, at this moment motor D ₁Does not rotate for negative pole entirely at two ends, has only motor D ₂Do inwardly running, make visor do the swing of direction left.

If press the place, the right of button (2), then K ₃Action, the open contact closure, normally closed contact is opened, and it is negative pole that 7 pin positions connect 2 pin positions, because of K ₁, K ₂Not action, 4,6 pin positions connect 1 pin position for anodal, at this moment motor D ₁Does not rotate for positive pole entirely at two ends, has only motor D ₂Do outwards running, make of the swing of visor do to right.

If will adjust back mirror, at this moment only need control key (1) is moved right, pull out the R place, at this moment K ₂, K ₃Connect with 5,8 pin positions respectively, other detailed process is same as described above not to be described in detail.

The utility model is compared with prior art: because having adopted button is pressed, push rod is ejected, promote shell Movable contact on body parallel slip on static contact, thus make the normally opened contact closure, and it is flat that normally-closed contact is opened The face way of contact makes the switch form of control circuit conducting, shutoff, and makes many group sets of contacts totally one power supply, Therefore this gauge tap compact conformation, volume are little, only just can control left and right two rearview mirrors with a switch In the turning to of 4 direct current generators, therefore operation, easy to use.
