Detailed Implementation

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] A dual-head assembled 9G automotive lens, such as Figures 1-4As shown, the lens includes a lens barrel 1, a front cover 2, a first lens 3, a first spacer 4, a second lens 5, a second spacer 6, a third lens 7, a third spacer 8, a fourth lens 9, a fifth lens 10, a fourth spacer 11, a sixth lens 12, a seventh lens 13, a fifth spacer 14, an eighth lens 15, a sixth spacer 16, a ninth lens 17, a seventh spacer 18, and a rear cover 19. The lens barrel 1 has two frustum-shaped limiting grooves in the middle for easy positioning. The left side of the lens barrel 1 is threadedly connected to the front cover 2. The left side of the lens barrel 1 has a convex structure to facilitate the fit between the front cover 2 and the lens barrel 1. The front cover 2 has a limiting groove in the middle and a concave structure inside for easy fit with the lens barrel 1. The left side of the lens barrel 1 contains, in sequence, the first lens 3, the first spacer 4, the second lens 5, the second spacer 6, the third lens 7, the third spacer 8, and the fourth lens 9. The first spacer 4 is located to the right of the first lens 3, the second lens 5 is located to the right of the first spacer 4, and the second spacer 6 is located to the right of the first lens 3. To the right of the second lens 5, the third lens 7 is located to the right of the second spacer 6, the third spacer 8 is located to the right of the third lens 7, and the fourth lens 9 is located to the right of the third spacer 8. Inside the right side of the lens barrel 1, the fifth lens 10 is placed. To the right of the fifth lens 10, the fourth spacer 11 is placed. Inside the fourth spacer 11, the sixth lens 12 is placed. To the right of the fourth spacer 11, the seventh lens 13 is placed. To the right of the seventh lens 13, the fifth spacer 14 is placed. To the right of the fifth spacer 14, the eighth lens 15 is placed. To the right of the eighth lens 15, the sixth spacer 16 is placed. To the right of the sixth spacer 16, the ninth lens 17 is placed. The right side of the ninth lens 17 is fitted with the seventh spacer 18. The fourth spacer 11, the sixth lens 12, the seventh lens 13, the fifth spacer 14, the eighth lens 15, the sixth spacer 16, the ninth lens 17, and the seventh spacer 18 are all located inside the right side of the lens barrel 1. The right side of the lens barrel 1 is threadedly connected to a rear cover 19, which has threads for easy installation and connection.

[0019] When using this device, first place the lens barrel 1 in the 9G vehicle lens assembly area, then stack the first lens 3, first spacer 4, second lens 5, second spacer 6, third lens 7, third spacer 8, and fourth lens 9 sequentially. Next, place the stacked first lens 3, first spacer 4, second lens 5, second spacer 6, third lens 7, third spacer 8, and fourth lens 9 inside the left side of the lens barrel 1. Then, align the front cover 2 with the left side of the lens barrel 1, and rotate the front cover 2 so that it moves to the right under the action of the threads. The front cover 2 limits the position of the first lens 3. Then, sequentially install the fifth lens 10, fourth spacer 11, sixth lens 12, seventh lens 13, fifth spacer 14, and eighth lens 15. The sixth spacer ring 16, the ninth lens 17, and the seventh spacer ring 18 are stacked and assembled. Then, the stacked fifth lens 10, fourth spacer ring 11, sixth lens 12, seventh lens 13, fifth spacer ring 14, eighth lens 15, sixth spacer ring 16, ninth lens 17, and seventh spacer ring 18 are placed inside the right side of the lens barrel 1.
