Abstract
The utility model relates to a gear drive structure for light adjusting devices of vehicle head lamps, which comprises a light adjusting nut on the light adjusting device. The gear drive structure for light adjusting devices of vehicle head lamps 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 provided with external screw threads. The external screw threads are meshed with screw threads of a central inner hole of a bevel gear. The other bevel gear is meshed with the bevel gear on the ball head screw. Drive screw rods for light adjustment are arranged on shaft lines of the bevel gears. The two bevel gears and the ball head screw are in a supporting shell body. The front ends of the Drive screw rods for light adjustment are provided with guide openings. The gear drive structure for light adjusting devices of vehicle head lamps has the advantages that the adjusting nut can be arranged to a suitable light adjusting point conveniently, and the adjusting nut is rotated by an operating worker with a tool conveniently so as to adjust and test a radiation angle of vehicle lights.
Description
Technical field
The utility model relates to a kind of drives structure, particularly a kind of gear drive structure of vehicle head lamp light modulating device.
Background technology
Construction along with highway, night is when running at high speed, the irradiating angle of its headlamp is if straight can not the change according to the fluctuating on road surface, when the descending of road surface, the road surface of travelling that headlamp can't shine, and when go up a slope in the road surface, the irradiation distance of its headlamp shortens greatly, above-mentioned two kinds of situations will directly influence the security of high speed traveling, therefore the headlamp of now middle-and-high-ranking vehicle all has the function of motorized adjustment illumination angle, mainly be the button operation by the driver or utilize vehicle-mounted computer to operate automatically, the speculum that motor-driven governor motion on the governor motion promotes headlamp sways, thereby changes the irradiating angle of headlamp.But at the installation testing of manufacturer or when being out of order maintenance, governor motion does not have, need carry out manual adjustments, existing adjustment structure is that adjusting nut directly is connected on the light modulation screw rod of dimming mechanism, but because the installation site of car light and the restriction of lamp body structure and car body, the workman can't rotate adjusting nut with instrument in debugging.
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 car light mechanism and body construction, the workman can't rotate the problem of adjusting nut with instrument in debugging, a kind of bevel gear drives structure that the light modulation point of adjusting nut can be moved on to correct position is provided.The utility model designs a kind of gear drive structure of vehicle head lamp light modulating device, comprise the light modulation nut on the light modulating device, it is characterized in that: the bulb nut is arranged on light modulating device, the bulb nut is connected with ball screw, at ball screw external screw thread is arranged, external screw thread meshes the screw thread of the central bore of a bevel gear, and other has a bevel gear to be meshed with bevel gear on the ball screw, and the light modulation drive screw is arranged on the axis of bevel gear.Two bevel gears and ball screw are positioned at a support housing.Front end at the light modulation drive screw has targeting port.The utility model has the advantages that easily adjusting nut to be installed to suitable light modulation point, the handled easily workman rotates adjusting nut with instrument, thereby regulates the illumination angle of test car light.
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 the bulb nut 1 on the light modulating device among the figure, it is characterized in that: bulb nut 1 is arranged on light modulating device, bulb nut 1 is connected with ball screw 2, at ball screw 2 external screw thread 3 is arranged, the screw thread 6 of the central bore 5 of external screw thread 3 engagements one bevel gear 4, other has a bevel gear 7 to be meshed with bevel gear 4 on the ball screw 2, and light modulation drive screw 8 is arranged on the axis of bevel gear 7.Two bevel gears 4,7 and ball screw 2 are positioned at a support housing 10.Front end at light modulation drive screw 8 has targeting port 9.Therefore the bulb nut 1 on the light modulating device can be moved on to handled easily workman operation by light modulation drive screw 8 with point of adjustment and reach position suitable on car light, directly be fixed on the car light because it regulates assembly, therefore regulate reliable, and good leak tightness, integral disassembly, assembly is convenient, and the targeting port 7 convenient edges of a knife that when the workman operates, on car body, can be screwed to light modulation drive screw 8 with screwdriver exactly, when the needs manual adjustment, the workman is inserted into targeting port 9 with screwdriver, promptly can be screwed to the edge of a knife that drives light modulation drive screw 8, then according to regulating direction clockwise or rotate counterclockwise light modulation drive screw 8, bevel gear 4 drives ball screw 2 and moves forward and backward under the screw thread 6 of bevel gear 4 central bore 5 drives, thereby the speculum that pulling bulb nut 1 drives on the car light rotates to change irradiating angle.
Claims (3)
1, a kind of gear drive structure of vehicle head lamp light modulating device, comprise the light modulation nut on the light modulating device, it is characterized in that: the bulb nut is arranged on light modulating device, the bulb nut is connected with ball screw, at ball screw external screw thread is arranged, external screw thread meshes the screw thread of the central bore of a bevel gear, and other has a bevel gear to be meshed with bevel gear on the ball screw, and the light modulation drive screw is arranged on the axis of bevel gear.
