[0015] As a preferred embodiment of the present invention, the method for adjusting the angle adjustment structure of a vehicle headlight comprises the following steps: Step 1: When adjustment is required, the operator starts the electric push rod to drive the slide plate to move, and the slide plate drives the connecting seat and the positioning plate to move, and the through slot on the positioning plate pushes the slide bar to slide, at this time, the rocker arm connected to the slide bar swings, and the rocker arm drives the entire external joint to rotate, and the external joint rotates to adjust the angle of the main light; Step 2: After the adjustment is completed, the through slot and the gantry cooperate with each other to make the through slot in a sealed state, and the slide bar cannot be separated from the through slot, ensuring that when the external connector and the lampshade are loosened, the slide bar is always in a limited state, ensuring that the main lamp is finally located in the lampshade, which is convenient for emergency use; Step 3: When the entire module of the main light needs to be replaced later, the operator pulls the lever to separate the lever and the slot, and then pushes the entire connection seat and the positioning plate to move, so that the through slot on the positioning plate and the notch on the gantry are finally aligned, and the slide bar is removed synchronously, and then a new module is installed. Then, the operator releases both hands, and the guide spring drives the slide bar to move to the initial state, that is, to the adjusted angle position, without manual readjustment, and the operation is simpler; Step 4: After the main light fails, the electric push rod is used to push the main light to the maximum angle offset position. At this time, the pressure rod inside the positioning cover is squeezed by the protrusion, and the pressure rod is pressed toward the inside of the positioning cover, and the sliding sleeve is driven to slide outward through the swing arm. The top plate on the sliding sleeve drives the spare light to move to the outside of the positioning cover, thereby facilitating emergency use; Step 5: After the top plate moves to the maximum distance, the edge of the extrusion plate on the top plate is blocked by the block.

At this time, the rocker arm connected to the slide bar swings, and the rocker arm drives the entire external joint to rotate. The external joint rotates to adjust the angle of the main lamp, and after the adjustment is completed, the through groove and the gantry cooperate with each other to make the through groove in a sealed state, and the slide bar cannot be separated from the through groove, which ensures that when the external joint and the lampshade are loose, the slide bar is always in a limited state, ensuring that the main lamp is finally located in the lampshade, and the reliability of use is stronger.

[0017] When the main lamp is replaced at a later stage of the present invention, the operator pulls the clamping rod to separate the clamping rod and the clamping slot, and then pushes the entire connecting seat and the positioning plate to move, finally making the through slot on the positioning plate correspond to the notch on the gantry, and the sliding rod is disassembled synchronously, and then a new module is installed, and then both hands are released, and the sliding rod is driven by the guide spring to move to the initial state, that is, to the adjusted angular position, at this time, no manual recalibration is required, and the reinstalled main lamp will be at the same angle as the original main lamp, thereby achieving the purpose of automatically adjusting the active position, making the adjustment easier.

[0018] After the main lamp of the present invention fails, the main lamp is pushed to the maximum angular offset position by the electric push rod. At this time, the pressure rod inside the positioning cover is squeezed by the protrusion, and the pressure rod is pressed toward the inside of the positioning cover, and the sliding sleeve is driven to slide outward by the swing arm. The top plate on the sliding sleeve drives the spare lamp to move to the outside of the positioning cover, thereby facilitating emergency use. After the top plate moves to the maximum distance, the edge of the extrusion plate on the top plate is blocked by the block. At this time, the squeezed extrusion plate rotates on the positioning shaft, and also drives the top plate to rotate, so that the spare lamp deflects toward the main lamp, thereby increasing the lighting effect.

The torsion spring can facilitate the guide seat 53 to remain in the initial state without being subjected to external force.

[0033] The present invention also discloses a method for adjusting the angle adjustment structure of a vehicle headlight, the steps of which are as follows: Step 1: When adjustment is required, the operator starts the electric push rod 3 to drive the slide plate 4 to move, and the slide plate 4 drives the connecting seat 422 and the positioning plate 425 to move, and the through slot 426 on the positioning plate 425 pushes the slide bar 233 to slide, at this time, the rocker arm 232 connected to the slide bar 233 swings, and the rocker arm 232 drives the entire external connector 2 to rotate, and the external connector 2 rotates to adjust the angle of the main light 222; Step 2: After the adjustment is completed, the through slot 426 and the gantry 411 cooperate with each other, so that the through slot 426 is in a sealed state, and the slide bar 233 cannot be separated from the through slot 426, ensuring that when the external connector 2 and the lampshade 1 are loosened, the slide bar 233 is always in a limited state, ensuring that the main lamp 222 is finally located in the lampshade 1, which is convenient for emergency use; Step 3: When the entire module of the main lamp 222 needs to be replaced later, the operator pulls the clamping rod 43 to separate the clamping rod 43 and the clamping slot 434, and then pushes the entire connecting seat 422 and the positioning plate 425 to move, and finally makes the through slot 426 on the positioning plate 425 correspond to the notch 412 on the gantry 411, and the slide bar 233 is disassembled synchronously, and then a new module is installed, and then the hands are released, and the slide bar 233 is driven by the guide spring 424 to move to the initial state, that is, to the adjusted angle position, without manual readjustment, and the operation is simpler; Step 4: After the main lamp 222 fails, the main lamp 222 is pushed to the maximum angle offset position by the electric push rod 3. At this time, the pressure rod 52 inside the positioning cover 5 is squeezed by the protrusion 11, and the pressure rod 52 is pressed toward the inside of the positioning cover 5. The sliding sleeve 523 is driven to slide outward by the swing arm 522, and the top plate 533 on the sliding sleeve 523 drives the backup lamp 541 to move to the outside of the positioning cover 5, so as to facilitate emergency use. Step 5: After the top plate 533 moves to the maximum distance, the edge of the extrusion plate 532 on the top plate 533 is blocked by the stopper 534. At this time, the extruded extrusion plate 532 rotates on the positioning shaft 531, and also drives the top plate 533 to rotate, so that the backup light 541 deflects toward the main light 222, thereby increasing the lighting effect.

[0034] The implementation principle of the vehicle headlight angle adjustment method and structure of this embodiment is as follows: When the angle of the main light 222 needs to be adjusted, the operator first starts the electric push rod 3 installed on the car keel 32, and drives the synchronous bracket 31 connected to the output end to move through the electric push rod 3. At this time, the synchronous bracket 31 drives the slide plate 4 at the end to move. At this time, the slide plate 4 can slide on the limit rod 41, and the limit rod 41 is fixed on the gantry 411, so at this time the slide plate 4 slides horizontally relative to the gantry 411.

[0035] A connecting seat 422 is installed on the skateboard 4. At this time, the connecting seat 422 is connected to the slot 434 through the clamping rod 43, so the connecting seat 422 slides synchronously with the skateboard 4, and the position of the positioning plate 425 on the connecting seat 422 changes. The through slot 426 on the positioning plate 425 can squeeze the sliding bar 233. At this time, the sliding bar 233 is affected by the thrust, and the rocker arm 232 connected to the sliding bar 233 rotates. The rotation center of the rocker arm 232 is installed with a rotating shaft 231. At this time, the rotating shaft 231 rotates on the fixed seat 23, and the rotating shaft 231 can also drive the external connector 2 at the end to rotate. The external connector 2 can drive the main lamp holder 22 and the main lamp 222 to deflect through the cable cover 221, thereby achieving the purpose of adjusting the angle of the main lamp 222.

[0036] When the slide bar 233 and the through slot 426 move, the through slot 426 and the gantry 411 cooperate with each other, and the through slot 426 and the notch 412 are separated in an alternating manner, so that the through slot 426 is in a sealed state, and the slide bar 233 cannot be separated from the through slot 426, ensuring that when the external connector 2 and the lampshade 1 are loosened, the slide bar 233 is always in a restricted state, ensuring that the main lamp 222 is finally located in the lampshade 1, will not affect the lighting, and has stronger reliability in use.

[0037] When the damaged main lamp needs to be replaced later, the operator first needs to pull the lever 43 to separate the block 433 at the end of the lever 43 from the block 433, thereby unlocking the connecting seat 422. After the lever 43 moves, the baffle 431 inside the lever 43 can squeeze the reset spring 432, thereby facilitating the reset operation later.

[0038] Then the operator can push the unlocked connecting seat 422, at which time the slider 42 at the bottom of the connecting seat 422 slides on the slide groove 421, and the slider 42 can also move on the guide rod 423, compressing the guide spring 424 at one end and stretching the guide spring 424 at the other end, and positioning the current position through the block 433, and finally the connecting seat 422 can drive the through groove 426 to move to the notch 412 of the gantry 411, and then the operator can remove the mounting plate 21, and finally take out all the structures connected to the mounting plate 21, and replace the main lamp 222 inside. After the replacement is completed, the operator can install it in reverse, and then the operator unlocks the block 433, and under the action of the two guide springs 424, the positioning plate squeezes the slide rod 233 to move to the initial state, that is, to the adjusted angle position, and no manual recalibration is required at this time. The reinstalled main lamp 222 will be at the same angle as the original main lamp 222, thereby achieving the purpose of automatically adjusting the active position, making the adjustment easier.

[0039] When the main lamp 222 fails in the later stage, the operator can deflect the failed main lamp 222 to the uppermost or lowermost position, and at this time, the position of the positioning cover 5 can be moved synchronously, and the pressure rod 52 on the positioning cover 5 can squeeze the top protrusion 11 of the lamp cover 1, so that the pressure rod 52 as a whole moves toward the inside of the positioning cover 5, and the swing arm 522 at the end of the pressure rod 52 squeezes inward, and the swing arm 522 drives the two sliding sleeves 523 to slide outward along the positioning rod 521, and the squeezing plate 532 and the top plate 533 on the positioning rod 521 drive the spare lamp 541 to move outward. The spare lamp 541 extends out from the positioning hole 51, and is reflected by the lampshade 1, so as to achieve the lighting effect. When the extrusion plate 532 moves, the edge of the extrusion plate 532 will eventually be squeezed by the stopper 534, and the movement of the extrusion plate 532 is blocked. However, the positioning shaft 531 on the guide seat 53 still pushes the extrusion plate 532 to move. At this time, the extrusion plate 532 starts to rotate, and the extrusion plate 532 drives the top plate 533 and the spare lamp 541 to rotate, so that the spare lamp moves toward the direction of the main lamp 222, thereby enhancing the lighting effect.

10. A method for adjusting the angle of a vehicle headlight, characterized in that: The method for adjusting the angle of a vehicle headlight applied to any one of claims 1 to 9 comprises the following steps: Step 1: When adjustment is required, the operator starts the electric push rod (3) to drive the slide plate (4) to move, and the slide plate (4) drives the connecting seat (422) and the positioning plate (425) to move, and the through groove (426) on the positioning plate (425) drives the slide bar (233) to slide, and at this time, the rocker arm (232) connected to the slide bar (233) swings, and the rocker arm (232) drives the entire external connector (2) to rotate, and the external connector (2) rotates to adjust the angle of the main light (222); Step 2: After the adjustment is completed, the through slot (426) and the gantry (411) cooperate with each other so that the through slot (426) is in a sealed state, and the slide bar (233) cannot be separated from the through slot (426), thereby ensuring that when the external connector (2) and the lampshade (1) are loosened, the slide bar (233) is always in a restricted state, ensuring that the main lamp (222) is finally located in the lampshade (1), which is convenient for emergency use; Step 3: When the entire module of the main lamp (222) needs to be replaced later, the operator pulls the lever (43) to separate the lever (43) and the slot (434), and then pushes the entire connecting seat (422) and the positioning plate (425) to move, and finally makes the through slot (426) on the positioning plate (425) correspond to the notch (412) on the gantry (411), and the slide bar (233) is removed synchronously, and then a new module is installed, and then the operator releases both hands, and the guide spring (424) drives the slide bar (233) to move to the initial state, that is, to the adjusted angle position, without the need for manual readjustment, and the operation is simpler; Step 4: After the main light (222) fails, the main light (222) is pushed to the maximum angle offset position by the electric push rod (3).
