Abstract
The invention discloses a lens assembly falling-preventing adjustment mechanism of an automobile head lamp. The lens assembly falling-preventing adjustment mechanism is composed of a lens support (1), a flying-wing ball buckle (2), a flying-wing nut (3), an adjustment screw (4) and a lamp shell (5), and a guiding groove (51) is formed in the position, provided with the adjustment screw (4), inside the lamp shell (5). The lens assembly falling-preventing adjustment mechanism is characterized in that the flying-wing ball buckle (2) is installed on the lens support (1), the flying-wing nut (3) is inserted in the guiding groove (51), the lower end of the adjustment screw (4) is fixed in an installation hole of the lamp shell (5) through a ring clamp (7), an adjustment rod at the upper end of the adjustment screw (4) is limited and fixed in the flying-wing nut (3) in a rotary mode, the flying-wing nut (3) is connected with the flying-wing ball buckle (2) on the lens support (1) by pressing a lens assembly (6), and dimming of the lens assembly (6) is achieved. The lens assembly falling-preventing adjustment mechanism is simple in structure, the lens assembly is prevented from falling in the dimming process and the vibrating test process, and the problem that dimming can not be carried out due to damage to threads of the flying wing nut is solved.
Description
Technical field
The present invention relates to automobile lamp industry, particularly relate to a kind of car headlamp set of lenses slip-off preventing governor motion.
Background technology
Automobile lamp is one of main accessory of automobile, and particularly car headlamp has strict requirement to the luminous intensity distribution performance of headlamp in national standard.And car headlamp needs to carry out the detection of luminous intensity distribution performance after installation, if deflection appears in light in the time detecting, be mainly to realize light by the governor motion on set of lenses or instant and near light speculum on adjusting light fixture to regulate.Dimming mechanism on current headlamp is 3 light modulations, and therefore producing is a bit vacant state, causes set of lenses or instant and near light speculum to occur obscission in light modulation process.In the time doing light fixture vibration experiment, often there will be set of lenses or instant and near light speculum to come off and can not meet GB10485-2007 standard in addition.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide a kind of car headlamp set of lenses slip-off preventing governor motion, by all-wing aircraft bulb buckle is installed on lens carrier, in gathering sill, be inserted with all-wing aircraft nut; Rotation adjustment screw drives all-wing aircraft nut along the upper and lower slip of gathering sill, until set of lenses light modulation is smooth.
The technical solution used in the present invention is: a kind of car headlamp set of lenses slip-off preventing governor motion, by lens carrier, all-wing aircraft bulb buckle, all-wing aircraft nut, adjustment screw, lamp housing composition, described lamp housing internal regulation screw installation place is provided with gathering sill, it is characterized in that: all-wing aircraft bulb buckle is installed on described lens carrier, in gathering sill, be inserted with all-wing aircraft nut, adjustment screw lower end fastens in lamp housing installing hole by plum blossom, the adjusting rod rotary stopper of upper end is fixed in all-wing aircraft nut, pressing set of lenses makes all-wing aircraft nut be connected with the all-wing aircraft bulb buckle on lens carrier, realize set of lenses light modulation.
Described all-wing aircraft nut be column rear side with all-wing aircraft, all-wing aircraft bottom is provided with two elastic foots, cylindrical tip and all-wing aircraft bulb buckle coupling part are bulb shape, column is provided with circular hole in bottom, circular hole top has one section without threaded area, bottom is threaded area.
In described all-wing aircraft bulb buckle, be provided with the bulb notch coordinating with all-wing aircraft nut top bulb.
It is without threaded portion that the adjusting rod top of described adjustment screw upper end is established one section, and it is without threaded portion that adjustment screw lower end is provided with one section by upper end, plum blossom card clip position, and two sections is threaded portion without threaded portion centre.
The present invention, simple in structure, prevent that lens subassembly from coming off in light modulation process and vibration test process, prevented again all-wing aircraft nut thread damage cannot light modulation problem.When light modulation, rotating adjustment screw drives all-wing aircraft nut along the upper and lower slip of gathering sill, until set of lenses light modulation is smooth.

Detailed description of the invention
Known by Fig. 1,2,3, a kind of car headlamp set of lenses slip-off preventing governor motion, is made up of lens carrier 1, all-wing aircraft bulb buckle 2, all-wing aircraft nut 3, adjustment screw 4, lamp housing 5, and all-wing aircraft bulb buckle 2 is installed on lens carrier 1; Lamp housing 5 internal regulation screw 4 installation places are provided with gathering sill 51, are inserted with all-wing aircraft nut 3 in gathering sill 51; Adjustment screw 4 lower ends are fixed in lamp housing 5 installing holes by plum blossom card 7, the adjusting rod of adjustment screw 4 upper ends is by the spacing circular hole 32 being fixed in all-wing aircraft nut 3 of screw thread rotation, after press the bulb 31 that set of lenses 6 makes all-wing aircraft nut 3 tops and be limited in the bulb notch 21 on all-wing aircraft bulb buckle 2, when light modulation, rotate adjustment screw 4 and drive all-wing aircraft nut 3 along the upper and lower slip of gathering sill 51, until set of lenses 6 light modulations are smooth.
In the time that the counterclockwise light modulation of operating personnel is excessive, owing to being 3 light modulations (left sides, right light regulating bolt 4, on one, lower light regulating bolt 4, a ball screw), work as a left side, when right light regulating bolt 4 is worked, can be subject to the upper of the other end, lower light regulating bolt 4 and the effect of ball screw pulling force, now light regulating bolt 4 adjusting rod upper end segments are also normal spacing in all-wing aircraft nut 3 port position without screw thread, after degree timing, can not damage the thread in all-wing aircraft nut 3 yet, play a protective role, all-wing aircraft nut 3 bottom two elastic foots and lamp housing 5 connect place's stress deformation in addition, upwards all-wing aircraft nut 3 is had to active force, can easily be transferred to threaded portion.
In the time that the clockwise light modulation of operating personnel is excessive; light regulating bolt 4 lower ends are positioned at all-wing aircraft nut 3 circular hole 32 top unthreaded portions without thread segment part; after degree timing, all-wing aircraft nut 3 threaded portions can not damaged without screw thread position in adjustment screw 4 bottoms, play a protective role.With this solve that set of lenses 6 light modulations come off and all-wing aircraft nut 3 thread damage cannot light modulation etc. problem.
