Description
Technical field
The utility model relates to a kind of auto parts and components, specifically is a kind of manual regulation structure of automobile front shining lamp adjustment device.
Background technology
The head lamp of automobile all is equipped with the light modulating device of regulating the car light irradiation angle, the principle of this device regulating irradiation angle is, car light is fixed in the lamp housing, the position that is car light immobilizes, and the car light back is provided with reflective silver bowl, and reflective silver bowl upper end is hinged with lamp housing, the push rod front end of reflective silver bowl lower end and light modulating device is hinged, by the forward-reverse of push rod, so that the hinge-point of reflective silver bowl around its upper end swings, realize the change of car light irradiation angle with this.
The motorized adjustment structure of automobile front shining lamp adjustment device comprises push rod and shell, be provided with electrical motor and driving device in the shell, push rod is provided with outside thread, the external thread rotary that push rod passes shell and push rod is combined on the negative thread of inner thread sleeve of shell, the motor output shaft rotation drives push rod through the driving device transmission and rotates, because push rod and inner thread sleeve screw, inner thread sleeve and shell are fixed, so the push rod opposite shell is advanced or retreated.
As shown in Figure 1, the manual regulation structure of the automobile front shining lamp adjustment device of prior art comprises adjusting sleeve pipe 101 and adjusting screw(rod) 102, it is outer and circumferentially spacing with push rod 103 that adjusting sleeve pipe 101 is enclosed within push rod 103, the lower end of adjusting sleeve pipe 101 is the first finishing bevel gear cuter 104, the end of adjusting screw(rod) 102 is the second finishing bevel gear cuter 105, lamp body is provided with through hole, when needing manual regulation, people push away before catching adjusting screw(rod) 102 via through holes, so that the first finishing bevel gear cuter 104 engagements of the second finishing bevel gear cuter 105 of the end of adjusting screw(rod) 102 and adjusting sleeve pipe 101 lower ends.
When people rotated adjusting screw(rod), adjusting screw(rod) can drive adjusting sleeve pipe and rotate, and adjusting sleeve pipe drives the push rod rotation, so that push rod advances or retreats.Because the engagement system between adjusting screw(rod) and the adjusting sleeve pipe is the engagement of cone tooth, the area of contact of this engagement system is little, and adjusting screw(rod) is beated easily during transmission, causes transmission unstable.
Summary of the invention
The technical problems to be solved in the utility model is that the manual regulation structure of the stable automobile front shining lamp adjustment device of a kind of transmission is provided.
Technical solution of the present utility model is, a kind of manual regulation structure with automobile front shining lamp adjustment device of following structure is provided, it comprises adjusting sleeve pipe and adjusting screw(rod), it is outer and circumferentially spacing with push rod that adjusting sleeve pipe is enclosed within push rod, be fixed with worm gear on the adjusting sleeve pipe, adjusting screw(rod) is provided with is with externally threaded worm screw section, the worm screw section of adjusting screw(rod) and the engagement of the worm gear of adjusting sleeve pipe.
After adopting above structure, the manual regulation structure of the utility model automobile front shining lamp adjustment device compared with prior art has the following advantages:
Owing to be fixed with worm gear on the adjusting sleeve pipe, adjusting screw(rod) is provided with is with externally threaded worm screw section, and the worm screw section of adjusting screw(rod) meshes with the worm gear of adjusting sleeve pipe, this engagement system, the area of contact of both engagement places is large, so can not beat in the transmission process, transmission process is stable.
As improvement, push rod footpath convex has projection, adjusting sleeve pipe is provided with the position-limited trough parallel with push rod, adjusting sleeve pipe is linked in the position-limited trough that push rod projection outer and push rod is positioned at adjusting sleeve pipe, like this, when adjusting sleeve pipe rotates, can the projection in being stuck in position-limited trough drive the push rod rotation, and because position-limited trough is parallel with push rod, push rod can unobstructively advance or retreat when rotating.
As improving again, the lamp housing of car headlamp is provided with through hole, and adjusting screw(rod) passes that the footpath convex has bulge loop and locating dowel pin on through hole on the lamp housing and the adjusting screw(rod), like this, during assembling, first from the interior through hole that outward adjusting screw(rod) is passed lamp housing, until bulge loop and envelope inner wall against, then stretch out the partial insertion locating dowel pin of lamp housing at adjusting screw(rod), under the effect of bulge loop and locating dowel pin, adjusting screw(rod), can't be seesawed on lamp housing by axial limiting, but still can flexible rotating.
