The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0043] like Figure 1-5 As shown, a dynamic image projection lamp includes a lamp body assembly 1, a bracket assembly 2, a control board 3 and a projection assembly 4. The lamp body assembly 1 includes a large lamp body 11, and a large front cover 12 and a rear cover 13 connected to the front and rear openings of the large lamp body 11.

[0044] The headlight body 11 is provided with a mounting plate 5, and the mounting plate 5 has two or more through mounting holes 6.

[0045] The projection component 4 includes a plurality of small projection lamps 7 disposed on the mounting holes 6;

[0046] A lockable angle adjustment component 8 is provided between the small projection lamp 7 and the mounting hole 6;

[0047] The small projection lamp 7 includes a small lamp body 71, and a lamp bead plate 72, a condenser lens group 73, a pattern sheet 74 and an imaging lens group 75 arranged sequentially in the small lamp body 71 along the light output direction.

[0048] The pattern pieces 74 of each small projection lamp 7 can be projected in sequence to form dynamic patterns;

[0049] The angle adjustment component 8 is used to adjust the angle so that the small projection lamp 7 cannot be removed from the mounting hole 6.

[0050] The control board 3 is located inside the rear cover 13 and is electrically connected to each of the small projection lamps 7.

[0051] In this embodiment, the dynamic pattern is decomposed into multiple static patterns and set on pattern pieces 74. The multiple pattern pieces 74 are then sequentially loaded into small projection lamps 7. Before operation, the angle of each small projection lamp 7 is adjusted. During operation, under the action of the control board 3, the multiple small projection lamps 7 are lit in sequence, projecting multiple static patterns in sequence. The dynamic pattern effect is created by utilizing the brief visual pause of the human eye. This outputs dynamic images to the preset scene, improving the projection display effect and interactive fun. Moreover, it is low in cost and stable and reliable in use.

[0052] In this embodiment, the projection effect of the static pattern is enhanced by the condenser lens group 73 and the imaging lens group 75.

[0053] Furthermore, such as Figure 2 , 3 As shown in Figures 4 and 5, the angle adjustment component 8 includes a front rotating outer ring 81, a rear rotating outer ring 82, and a rotating inner ring 83.

[0054] The outer surface of the rotating inner ring 83 is provided with a first spherical surface 10, and the rotating inner ring 83 is sleeved on the small lamp body 71;

[0055] The front rotating outer ring 81 and the rear rotating outer ring 82 are coaxially arranged at the front and rear of the mounting hole 6, respectively, and the front rotating outer ring 81 is tightly connected to the rear rotating outer ring 82 through the mounting plate 5;

[0056] After the front rotating outer ring 81 and the rear rotating outer ring 82 are connected, they cover the outer periphery of the mounting hole 6. Moreover, the inner surface of the front rotating outer ring 81 and the rear rotating outer ring 82 together forms a second spherical surface 20 that matches the first spherical surface 10.

[0057] The inner rotating ring 83 is connected to the outer rotating ring 81 and the outer rotating ring 82 via the first spherical surface 10 and the second spherical surface 20, which are angularly adjustable and cannot be detached.

[0058] In this embodiment, since each small projection lamp 7 is installed in a different position, the light emission angle of each projection lamp needs to be adjusted to ensure that the angle and area of ​​the pattern projected by each small projection lamp 7 meet the requirements. Therefore, through the spherical surface structure design, the projection angle of the small projection lamp 7 can be adjusted at will, so that the patterns projected by multiple projection lamps perfectly overlap.

[0059] Furthermore, such as Figure 2 , 3 As shown in Figure 4, in order to restrict the degree of freedom of rotation of the inner rotating ring 83 relative to the outer rotating ring without the action of external force, and to ensure that the small projection lamp 7 with the angle adjusted is fixed, a limiting rubber ring 9 is provided between the first spherical surface 10 and the second spherical surface 20.

[0060] The first spherical surface 10 has an annular groove 10a for installing the limiting rubber ring 9.

[0061] Furthermore, such as Figure 2 , 5 As shown, the small projection lamp 7 also includes a heat sink 76 and a small front cover 77 that are respectively connected to both ends of the small lamp body 71;

[0062] The back of the LED bead board 72 is connected to the heat sink 76, and the surface is connected to the condenser lens group 73 by screws.

[0063] The imaging lens group 75 is threadedly connected to the small front cover 77;

[0064] The pattern piece 74 is placed inside the small lamp body 71 by the placement bracket 30;

[0065] A protective mirror 40 is provided on the inner side of the large front cover 12.

[0066] In this embodiment, in order to improve the overall stability of the small projection lamp 7, the heat sink 76 and the small front cover 77 are locked to the small lamp body 71 by screws; in order to ensure that the pattern piece 74 is stably installed in the small lamp body 71, an installation groove extending from the heat sink 76 to the inside is opened in the small lamp body 71, and the placement bracket 30 is set in the installation groove and fixed in the installation groove by the condenser lens group 73.

[0067] Furthermore, such as Figure 1 , 2 As shown in Figure 5, in order to improve waterproof and dustproof performance, waterproof rubber rings 50 are provided between the headlight body 11 and the rear cover 13 and the large front cover 12.

[0068] Waterproof screws 60 are provided on the wire hole of the rear cover 13.

[0069] Furthermore, such as Figure 1 , 2 As shown in Figures 3 and 4, the bracket assembly 2 includes a bracket 21 and a bracket screw 22.

[0070] The bracket screw 22 is equipped with a handle. After passing through the connecting hole of the bracket 21, the bracket screw 22 is threadedly connected to the threaded hole of the headlight body 11.

[0071] In this embodiment, the pitch angle of the headlight body 11 can be adjusted by tightening the lever bracket screw 22.

[0072] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
