Description
Technical field
The present invention relates to the tilting equipment of accommodation reflex mirror in a kind of car light or car light lamp socket support C, particularly, the present invention relates to shifting block type dimming mechanism used a kind of embedded nut and shifting block type dimming mechanism thereof.
Background technique
The Headlamps of automobile and Front Fog Lamp generally all need certain light regulation mechanism to adjust angle between reflector (or PES lamp socket support C) and the direction of traffic, and the light that light fixture is penetrated meets lighting requirement.
Present light regulation mechanism is mostly realized by the adjusting light regulating bolt and the pair that is threaded of light modulation nut.Accompanying drawing 1 is comparatively typical a kind of light regulation mechanism at present, is made up of screw A and nut B.Screw A fixes by floor clip D and lamp body E, simultaneously can be along its axial rotation.The screw A the other end is fixed with the fluted disc of regulating usefulness or bevel gear nut B and screw A by being threaded, and is connected with the cooperation plane of reflector F (or lamp socket support C).Reflector F (or lamp socket support C) can be around running shaft clockwise or be rotated counterclockwise.
Its working principle is: by stirring the bevel gear (fluted disc) that is connected with light regulating bolt A, rotary light adjustment screw A, light regulating bolt A drives light modulation nut B and does straight line motion, light modulation nut B drives the light modulation support that is spirally connected with it, the light modulation support promotes connected reflector F (or lamp socket support C) and rotates around reflector running shaft (or pivot point), thus, reach the effect of angle between accommodation reflex mirror F (or lamp socket support C) and the substantially horizontal (direction of traffic).
Because the straight line motion of nut B is controlled by the rotation of adjusting screw A, do not having under the situation of outer moment of torsion, adjusting screw A can not rotate, nut B can moving linearly, utilize not in collinear 3 principles of determining a plane, also do not have relative movement between reflector F and the lamp body E.
The defective of above-mentioned this controlling mechanism is:
Need during assembling earlier light regulating bolt A and lamp body E to be fixed, nut B and reflector F are assembled, again light regulating bolt A is screwed into nut B, so assembly process is restricted.Because nut B generally is installed in the back side of reflector F, need use special fixture location reflector F during assembling, light regulating bolt A accurately could be screwed into nut B, obviously as seen, this installation method causes the assembly technology complexity.
In addition, nut B generally will be assembled to a certain predeterminated position of the helical thread portion of light regulating bolt A during assembling, and to guarantee forward and reverse adjusting surplus, this just causes installation time longer, and default initial position is not easy to measure.
Again, when the accommodation reflex mirror angle, the position of nut B can not get restriction.As shown in Figure 2, forward is regulated too much, can cause nut B to deviate from screw; Oppositely regulate too much, nut B and light regulating bolt A root are interfered, cause the sliding tooth of screw thread of nut B to lose efficacy.
