[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] Reference Figure 1-4 As shown, the adjustable LED vehicle light includes a light housing 1, a lampshade body 2 mounted on the light housing 1, a mounting plate 3 inside the light housing 1, and an LED lamp body 4. A support plate 5 is mounted on the mounting plate 3, and an arc-shaped groove 6 is formed on the support plate 5. An arc-shaped drive plate 7 is slidably mounted inside the arc-shaped groove 6. An arc-shaped sliding groove 601 is formed at the bottom end of the arc-shaped groove 6. The bottom end of the drive plate 7 is slidably connected to the arc-shaped sliding groove 601. A slider is provided at the bottom end of the drive plate 7 and slidably connected to the arc-shaped sliding groove 601. The LED lamp body 4... A rack 701 is provided on the upper surface of the drive plate 7, and a drive assembly meshing with the rack 701 is provided on the rear end face of the drive plate 7. A guide follower assembly is provided on the front end face of the drive plate 7. The drive assembly drives the drive plate 7 to reciprocate along the arc-shaped groove 6. The guide assembly guides and limits the movement direction of the drive plate 7, making the movement of the drive plate 7 more stable. The drive assembly drives the drive plate 7 to move, thereby adjusting the illumination angle of the LED lamp body to adjust the illumination area of the vehicle lamp. In some special road conditions, this improves the driver's visibility area and prevents the occurrence of danger.
[0020] The drive assembly includes a first groove 801, a second groove 802, a drive gear 803, a motor 804, and a driven gear 805. The first groove 801 and the second groove 802 are symmetrically located on the support plate 5 at the rear end of the arc-shaped groove 6. Both the first groove 801 and the second groove 802 are connected to the arc-shaped groove 6. The drive gear 803 is rotatably disposed inside the second groove 802, and the driven gear 805 is rotatably disposed inside the first groove 801. The motor 804 is located at the bottom end of the support plate 5, and its drive end is connected to the drive gear 803. The motor 804 is connected to the vehicle's on-board computer. When the vehicle turns, the vehicle computer drives the motor 804 to work, which drives the drive plate 7 to adjust the illumination angle of the LED lamp body 4, providing supplementary illumination to the blind spot when turning, increasing the driver's visibility area at night, and improving driving safety. The drive gear 803 and the driven gear 805 are both engaged with the rack 701. The motor 804 drives the drive gear 803 to rotate. Since the drive gear 803 is engaged with the rack 701, it drives the drive plate 7 to move. The driven gear 805 rotates together with the drive plate 7 as it moves, limiting the movement of the drive plate 7 and making its movement more stable.
[0021] The guide follow-up component includes a third groove 901, a fourth groove 902, a first limiting wheel 903, and a second limiting wheel 904. The third groove 901 and the fourth groove 902 are symmetrically arranged at the front end of the arc-shaped groove 6, and both the third groove 901 and the fourth groove 902 are connected to the arc-shaped groove 6. The first limiting wheel 903 is rotatably disposed inside the third groove 901, and the second limiting wheel 904 is rotatably disposed inside the fourth groove 902. The outer surfaces of the first limiting wheel 903 and the second limiting wheel 904 abut against one end of the driving plate 7. The first limiting wheel 903 and the second limiting wheel 904 rotate together with the movement of the driving plate 7, and cooperate with the drive gear and the driven gear 805 to limit the movement of the driving plate 7 in the front-back direction, so that the adjustment of the LED lamp body 4 is more stable.
[0022] A fixing block 10 is symmetrically arranged on the upper surface of the bearing plate 3. A connecting arm 11 is arranged on the upper surface of the fixing block 10. One end of the connecting arm 11 extends above the driving plate 7. A mounting frame 12 is rotatably arranged at the bottom end of the connecting arm 11. The mounting frame 12 can rotate at the bottom end of the connecting arm, so that the third limiting wheel 13 can roll together with the movement of the driving plate 7. The mounting frame 12 is fixed in the current position by bolts. The third limiting wheel 13 is rotatably arranged inside the mounting frame 12. The outer surface of the third limiting wheel 13 abuts against the upper surface of the driving plate 7. Since the connecting arm 11 is fixed on the fixing block 10, its height is fixed. The third limiting wheel 13 abuts against the upper surface of the driving plate 7. The third limiting wheel 13 further restricts the vertical jump of the driving plate 7. When the driving plate 7 moves, the third limiting wheel 13 will not interfere with its movement direction, making it more stable.
[0023] A mounting bracket 14 is provided on the upper surface of the drive plate 7, and the LED lamp body 4 is mounted on the mounting bracket 14.
[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
