Detailed description of the invention
It should be noted that, in the situation that not conflicting, in the embodiment in the utility model and embodimentFeature can combine mutually.
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
The present embodiment relates to a kind of Far-near lamplight switchover device, and as shown in Figure 1, it comprises fixing shadow shield 1,Be pivoted on the movable light shield plate 2 on described fixing shadow shield 1, be fixed on moving on described fixing shadow shield 1Power apparatus 3.
Wherein, as shown in Figure 2, the platy structure that the entirety of movable light shield plate 2 is elongated, near itsEdge, is provided with the axle sleeve 201 projecting upwards, and the middle part of axle sleeve 201 forms through hole 202, meanwhile, and canMoving shadow shield 2 is provided with and the corresponding through-hole structure of through hole 202, and by the setting of this through hole, can be canThe pivot joint of moving shadow shield 2 on fixing shadow shield 1 provides a firm pivotable that basis is installed.
In movable light shield plate 2 one sides, be provided with the connecting portion 203 extending along movable light shield plate 2 widths,Connecting portion 203 is provided with long slot bore 204, and what long slot bore 204 was penetrating is arranged on connecting portion 203, and it alsoIt can be the groove shape with certain depth. The length of long slot bore 204, along the width of described movable light shield plate 2Direction arranges. Be provided with a horn shape portion 205 at the front end of movable light shield plate 2, by this horn shape portion 205, canLight type when realizing dipped beam. On the movable light shield plate 2 of described axle sleeve 201 opposite ends, be provided with upwards curvedAfter folding, extend the guiding auxiliary section 206 arranging, be provided with at the afterbody of guiding auxiliary section 206 leading that width diminishesTo matching board 207.
As shown in Figure 3, its entirety is similarly platy structure to the structure of fixing shadow shield 1, in the time of assembling, and shouldFixing shadow shield 1 is fixed on speculum. On fixing shadow shield 1, be provided with setting corresponding to through hole 202Installing hole 101, drive-connecting shaft 4 can connect after installing hole 101, through hole 202, realizes movable light shield plate 2Pivot joint on fixing shadow shield 1. In order to improve stability, in the present embodiment, establish at fixing shadow shield 1Have and the sunk structure 102 of movable light shield plate 2 shape adaptations, what movable light shield plate 2 can coincide is engaged inIn this sunk structure 102, guiding auxiliary section 206 can be leant out by sunk structure 102.
The power set 3 of the present embodiment adopt electromagnet structure, and it can adopt existing electromagnetic actuator deviceStructure, simply, this electromagnet structure comprises coil and return spring, solenoid obtains when electric,Can drive axostylus axostyle motion as described below, after solenoid dead electricity, return spring drives axostylus axostyle to reset. MovingPower apparatus 3 is fixed on fixing shadow shield 2, and its clutch end is connected with axostylus axostyle 5, and axostylus axostyle 5 has evenBe connected to the horizontal segment 501 of power set 3 clutch ends, and arrange with 501 one-tenth obtuse angles of horizontal segment,Be embedded into the bending segment 502 in long slot bore 204. In bending segment 502 and part of horizontal section, be sheathed with everyHot jacket 503. By the setting of collet 503, can prevent that the heat of movable light shield plate 2 from passing to powerDevice 3, effectively to improve the service life of power set. Collet 503 can adopt plastics etc. to haveThe material of low thermal conductivity is made.
Power set 3 when electric, the horizontal segment 501 of drive shaft rod 5 moves axially, further the company of drivingMeet portion 203 and pull whole movable light shield plate 2 pivotables, to realize the switching of distance-light. For further raisingResult of use, the axis direction of bending segment 502 and the non-perpendicular setting of slotted hole place plane, to connect in drivingWhen meeting portion 203 and moving, for this driving provides a cushioning effect power, prevent from driving the generation of stuck phenomenon.
Accuracy in order to ensure movable light shield plate 2 in distance-light handoff procedure, as shown in Figure 1, solidDetermining shadow shield 1 is provided with the pivotable of movable light shield plate 2 is carried out to spacing limited block 6. At movable light shield plate 2Be switched to while contact with limited block 6, limited block 6 defines the continuation pivotable of movable light shield plate 2, prevents wholeIndividual failure of apparatus, the stationarity while contact for further raising is spacing, is formed with acting surface on limited block 6601, this acting surface 601 is a planar structure, can increase the contact area with movable light shield plate 2. In addition,In order to reduce the noise in distance-light handoff procedure, in the present embodiment, limited block 6 adopts block rubber, and it is notOnly can play the effect that reduces noise, can provide cushioning effect simultaneously.
In order to improve movable light shield plate 2 traveling comforts, on fixing shadow shield 1, be provided with movable light shieldThe guide part 7 that the pivotable of plate 2 leads. As shown in Figure 1, guide part 7 has and fixing shadow shield 1The fixed head 702 being connected, and be connected with fixed head 702 and be formed at the spacing of fixing shadow shield 1 topPlate 701, this limiting plate 701 arranges with the upper surface spacing of fixing shadow shield 1, and movable light shield plate 2 is freely207 of the guiding matching boards at end place extend in the spacing between limiting plate 701 and fixing shadow shield 1.
In order to make overall structure compacter, on limiting plate 701, be formed with to fixing shadow shield 1 direction and prolongThe plug-in mounting plate 703 of stretching is provided with the plug-in opening 602 inserting for plug-in mounting plate 703 on limited block 6. Like this, limitPosition piece 6 and guide part 7 form integrative-structure, have improved the stability of whole application of installation process.
In order to realize, the pivoting angle of movable light shield plate is further limited, guide part 7 has limiting section704, this limiting section 704 is upwards extended and is arranged to form an arcuation by fixed head 702, and is finally formed atLimiting plate 701, relative with plug-in mounting plate 703 opposite side. Like this, guiding matching board 207 is limited inRegion between acting surface 601 and limiting section 704.
In use, by power set, axostylus axostyle 5 is driven, axostylus axostyle 5 drives movable light shield plate 2 pivotsTurn, finally to realize the switching of headlight for vehicle light.
