[0029] In the embodiment, the off-road vehicle type of the new energy electric vehicle is provided with a plurality of headlamps, which are used for increasing the brightness of the field of view, and the brightness and the illumination range can be improved by using the headlamp.

[0030] When the illumination range and the illumination angle of the headlamp are adjusted, the control of the lead screw motor set 41 and the electric cylinder 51 is completed.

[0031] The lead screw motor set 41 is used for realizing the synchronous reverse rotation of the two first gear plates 32, the motor of the lead screw motor set 41 drives the rotation of the lead screw, so as to realize the sliding of the first rack block 45 driven by the lead screw block 42, the synchronous reverse rotation of the two first gear plates 32 engaged with each other is realized by the first rack block 45, so as to realize the rotation of the LED headlamp 02 on the horizontal XY plane, the illumination angle of the LED headlamp 02 can be dispersed, the illumination range can be expanded, or the illumination range of the LED headlamp 02 can be reduced, the illumination directions of the two LED headlamps 02 are overlapped, and the illumination intensity is improved.

[0032] When the electric cylinder 51 is controlled to move, the piston rod of the electric cylinder 51 extends, drives the two push blocks 54 to move, the push blocks 54 are used for pushing the single rod bearing 343, the single rod bearing 343 pushes the first sliding block 341 to slide on the first sliding rail 331, and the rack block 342 drives the gear disc rotating frame 021 engaged with the rack block 342 to rotate, so that the LED headlamp 02 rotates in the vertical ZX plane, and the range of the LED headlamp 02 is automatically adjusted.

[0033] When the first gear disc 32 rotates, the single rod bearing 343 with the increased position is always located in the limiting sliding groove 541.

[0034] In order to prevent the exposed LED headlamp 02 from being damaged in the field, the protective shell 1 can be opened and shielded in front of the shell 01, and the protective shell 1 cooperates with the shell 01 to effectively protect the LED headlamp 02. When the protective shell 1 needs to be opened, the piston rod of the electric cylinder 51 is first controlled to retract, the roller rod 542 is displaced and contacts the push plate frame 62, the roller of the roller rod 542 slides on the circular arc push surface 6221 in a sliding fit, so that the roller rod 542 pushes the push plate frame 62 to move downward on the first sliding rod frame 612 and compresses the first spring 613.

[0035] During the descending process of the push plate frame 62, the supporting roller 623 compresses the sliding plate 721 below, so that the push plate frame 62 descends, the sliding plate 721 is simultaneously pressed downward to descend on the second sliding rod frame 713, and the second spring 714 retracts. When the sliding plate 721 moves downward, the lead screw motor set 41 drives the lead screw sliding block 42 to slide, so that the limiting clamping plate 421 is located below the limiting plate 723.

[0036] After the shell push plate 72 descends, the push plate 724 on one side changes from being clamped at the second plug plate 614 and the first plug plate 222 to being completely separated from the second slot 6141 and entering the first slot 223, and the limiting plate 723 descends into the gap between the limiting clamping plates 421. At this time, the lead screw motor set 41 works, the lead screw sliding block 42 drives the two clamped shell push plates 72 to slide on the push plate sliding seat 71, and the push plate 724 pushes the two shell driving blocks 22, so that the second rack sliding block 221 is displaced, drives the second gear disc 12 engaged with the second rack sliding block 221 to rotate, thereby rotating the protective shell 1, closing the protective shell 1 in front of the shell 01, thereby playing a protective role. When the shell push plate 72 moves horizontally, the limiting roller 722 is resisted by the limiting part 6111 plate body, preventing the shell push plate 72 from rising.

[0037] When the protective shell 1 is opened, the screw rod motor set 41 controls the screw rod slider 42 to reset, the electric cylinder 51 extends, the roller rod 542 no longer pushes against the push plate frame 62, the first spring 613 releases the elastic potential energy, so that the push plate frame 62 is lifted for resetting, the shell push plate 72 is pushed up by the second spring 714 to release the elastic potential energy, and is clamped between the second plug plate 614 and the first plug plate 222 again, so that the shell push plate 72 can be clamped by the second plug plate 614 to prevent displacement in the opened state of the protective shell 1.

[0038] When the angle range of the LED headlamp 02 is adjusted, the roller rod 542 cannot completely push down the push plate frame 62.

[0039] The present application realizes the automatic control of the integration of lighting and protection through the cooperation of the screw rod adjusting mechanism 4, the electric cylinder adjusting mechanism 5, the limiting mechanism 6 and the shell pushing mechanism 7, and can automatically drive the protective shell 1 to open and close through the shell guiding mechanism 2 while realizing the automatic adjustment of the illumination angle of the LED headlamp 2 through the headlamp steering mechanism 3, so as to effectively protect the headlamp and prevent the LED headlamp 2 from being broken by stones and impurities in the case that the electric vehicle headlamp does not need to be illuminated.

[0040] The protective shell 1 has the automatic opening and closing function, the second gear plate 12 is driven to rotate through the shell guiding mechanism 2, the protective shell 1 is driven to expand along the guiding slide rod 011 or to be stored in the protective shell storage cavity 012, and the effective protection of the LED headlamp 02 is realized, which is especially suitable for off-road, snow and other harsh environments.

[0041] In the horizontal direction, the first rack slider 45 is driven to rotate the first gear plate 32 through the screw rod adjusting mechanism 4, the synchronous reverse rotation of the LED headlamp 02 in the XY plane is realized, so that the illumination angle adjustment and the convergence and divergence of the light beam can be realized.

[0042] In the vertical direction, the headlamp adjusting block 34 is pushed through the electric cylinder adjusting mechanism 5, the gear plate rotating frame 021 is driven to rotate through the rack block 342, and the pitch adjustment of the LED headlamp 02 in the ZX plane is realized.

[0043] The limiting mechanism 6 cooperates with the shell pushing mechanism 7, when the light angle is adjusted, the push plate frame 62 is not completely pressed down, the shell push plate 72 remains in the clamped state, and the stable opening of the protective shell 1 is ensured.

[0044] When the protective shell needs to be closed, the electric cylinder 51 is retracted to drive the roller rod 542 to push down the push plate frame 62, so that the shell push plate 72 is disengaged from the clamping and is driven to move horizontally by the screw rod slider 42, and the shell driving block 22 is pushed to complete the closure of the protective shell.

[0045] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
