Abstract
The utility model relates to a drive structure for light adjusting devices of vehicle headlights, which comprises a light adjusting device. The drive structure for light adjusting devices of vehicle headlights is characterized in that a ball head nut is arranged on the light adjusting device, the ball head nut is connected with a ball head screw which is sheathed with a rotating seat, external screw threads of the ball head screw are meshed with internal screw threads on a shaft hole of the rotating seat and the top end of the ball head screw is provided with a connector head. The drive structure for light adjusting devices of vehicle headlights has the advantages of simple structure and convenient operation, and a drive mechanism can be arranged by requiring tiny space only.
Description
Technical field
The utility model relates to a kind of drives structure, particularly a kind of drives structure of vehicle head lamp light modulating device.
Background technology
High speed development along with science and technology, also in order to improve traveling security, present vehicle head lamp has adopted the function of motorized adjustment illumination angle, it by the driver button operation or utilize vehicle-mounted computer to operate automatically, the speculum that promotes headlamp sways, change the irradiating angle of headlamp, headlamp can illuminate road in the travelling of abrupt slope so that vehicle has on mountain highway.But when the installation testing of manufacturer and vehicle damage when repairing, the automatic governor motion of headlamp does not have, just need carry out manual adjustments this moment, the complex structure of more existing governor motions, and in order to satisfy the designing requirement of vehicle to car light, the locus that governor motion can be installed on car light is very limited, therefore the drive unit of the more existing front shining lamp adjustment device that takes up room bigger can't be installed, and demand a kind of drive unit of the front shining lamp adjustment device that can meet design requirement urgently.
Summary of the invention
The purpose of this utility model is the restriction that the installation of adjusting nut in the solution prior art is subjected to the installation site, need to utilize complicated steering structure that adjusting nut is installed to the light modulation point, cause complex structure, the problem that cost rises provides a kind of flexible axle drives structure that adjusting nut can be installed in any light modulation point.The utility model designs a kind of drives structure of vehicle head lamp light modulating device, comprise light modulating device, it is characterized in that: the bulb nut is arranged on light modulating device, the bulb nut connects ball screw, ball screw is with rotation seat, internal thread engagement on the external screw thread of ball screw and the rotation seat axis hole has connector on the top of ball screw.The utility model has the advantages that simple in structure, easy to use, as long as very little space can install driving mechanism.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise light modulating device 1 among the figure, it is characterized in that: bulb nut 2 is arranged on light modulating device 1, and bulb nut 2 connects ball screw 3, and ball screw 3 is with rotation seat 4, the external screw thread 5 of ball screw 3 and 7 engagements of the internal thread on rotation seat 4 axis holes 6 have connector 8 on the top of ball screw 3.Since in car light as long as a ball head screw 3 bulb nut 2 that can promote on the light modulating device 1 moves forward and backward, therefore can in narrow and small car light space, dimming drive device be installed, in the use, rotation seat 4 is installed on the car light, connector 8 can utilize flexible axle to connect, make things convenient for the position so that drive point adjusted to, after connector 8 is rotated, ball screw 3 had both become a screw mandrel along rotation seat 4 axis holes 6 directions, the rotation of positive and negative two directions by connector 8, ball screw 3 is finished and is moved forward and backward, thereby the bulb nut 2 of pulling on light modulating device 1 moves forward and backward, speculum on the last headlamp sways, and finishes the change of headlamp illumination angle.
