Abstract

The utility model relates to a steering device of an electric controlled rear-view mirror, particularly a steering device which is installed in the rear-view mirror of an automobile and is suitable for the vehicles of various model number. When the utility model is used, the angle of the lens of the rear-view mirror is automatically regulated; so the visual angle can be enlarged. The utility model is composed of a motor, a motor cover and a regulating mechanism. The motor is installed at a pedestal, and the rear cover plate of the motor is provided with a speed reducing device. By using a floating ring and a rack, the regulating mechanism is engaged with the gear wheel of the shaft end of the motor, and the rack is connected with the regulating mechanism. A floating rod is movably connected with the floating ring, and the floating rod is connected with the top column of the spacer plate of the pedestal. So long as a control switch installed on the handle of an automobile door is pressed, the utility model can do upper, lower, left and right swing motion or universal rotation; thereby, a view-mirror plate which is provided with the view-mirror and is connected with the utility model can be driven to do motion; so the angle of the rear-view mirror can be regulated.

Description

The commutator of automatically controlled back mirror

The utility model relates to a kind of vehicle body fittings, and particularly a kind of being installed in the automobile rearview mirror is connected with the visor plate that has visor, is used for the angle of automatically regulating back mirror eyeglass, with the commutator of the automatically controlled back mirror that enlarges the visual angle.

The back mirror of existing domestic car is most still by the manual adjusted of chaufeur, and is inconvenient, dangerous.

The patent No. 95207812.0 " the universal back mirror of motorcar electric " also provides a kind of and just can regulate the eyeglass angle in operator's compartment, the driven rearview mirrors of broadening one's vision, but its complex structure.

The purpose of this utility model is to provide a kind of commutator of the automatically controlled back mirror that uses of suiting on various model vehicles, just can the automatically regulating back mirror in operator's compartment in the angle of eyeglass, to enlarge the purpose at visual angle.

The utility model is achieved in that the commutator of automatically controlled back mirror is by being installed in base, motor, motor cover and the regulating mechanism of band speed reduction gearing are formed in the back shroud, and regulating mechanism by floating ring by connected tooth bar and motor shaft end gear mesh, floating lever and floating ring flexible connection again with the base dividing plate on fore-set connect and compose.

Fig. 2. the A-A view of Fig. 1.

Fig. 3. fore-set bonded assembly part sectional view on floating lever and the dividing plate.

Fig. 4. the wheel and rack mesh schematic representation.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described

Floating ring (1) is an annular arrangement, upper surface is fluted, 4 buckles (8) of five equilibrium are arranged on the strengthening rib, outer wall, the cylindrical fixed leg (4) that vertically has blind hole is each other arranged on the inwall, the projection (2) of two band deep-slotted chip breakers of symmetry is arranged on 2 fixed legs (4) midway location, and lower surface is sphere and forms rounded channels (14).

Base (10) is circle basin shape, circle, square through hole, strengthening rib, stay bearing plate, positioning groove, positioning rib, vertical partition plate (15) are arranged on the bottom surface, dividing plate (15) crown center has a circular arc fore-set (16), dual-side respectively has a crescent projection (17), and the upper end is that the sphere that has five equilibrium 4 breach cooperates with the sphere and the rounded channels (14) of floating ring (1) lower end.

Floating lever (3) has ⊥ shape projection for there is ellipse hole at two ends on the top, the centre is the arc of two band long arc-shaped holes (19), and a groove (18) is arranged in the middle of the inwall.

There are seam and wire hole in back shroud (12) edge, and inside face has the joint pin of 3 band through holes.

The annular arrangement that dust boot (13) is made into by elastomeric material.

Tooth bar (5) top one side is a spheroid, and a side is a triangle body, and the lower end is an elongate body, and wherein one has and gear (6) ingear tooth on vertical with the top spheroid rectangular.

Two motors (9) that have a speed reduction gearing are placed on the positioning groove on base (10) bottom surface upper spacer (15) both sides, on the positioning rib, in the through hole on tooth bar (5) the insertion base (10), and the gear (6) of motor (9) axle head and tooth bar (5) are meshed, cover motor cover (11) again it is fixed on the speed reduction gearing of motor (9) with the projection on it.

Floating lever (3) is embedded on 2 projections (2) on floating ring (1) inwall with the projection on the top, make it can do 180 ° rotation along the deep-slotted chip breaker on it.

The floating ring (1) that will have floating lever (3) is connected with the sphere of the sphere of lower end and base (10) upper end and is integral, and the fore-set (16) on the dividing plate (15) is buckled in the groove (18) on the floating lever (3), projection (17) is buckled in the long arc-shaped holes (19) of floating lever (3), the fore-set (16) that floating lever (3) can center on the dividing plate (15) rotates, spheroid with tooth bar (5) top is buckled in the fixed leg (4) again, cover back shroud (12), peripheral base (10), floating ring (1) are located to put dust boot (13) commutator and are assembled into.

During use, put into copper sheathing (20) in 3 through holes on base (10), and pass through hole on motor cover (11), base (10), the back shroud (12) with 3 screws and be fixed in the screw on the automobile rearview mirror base plate, use 4 buckles (8) on the floating ring (1) that it is buckled in the reverse groove button internal fixation (figure draws) of the visor plate that has visor again.With the whole back mirror that assembles, it is outdoor to be installed in vehicle drive, carefully connects the wire and just can use.
