Referring to Figures 5, 6, and 10, the light-emitting unit 3 can rotate relative to the lamp holder 22 so that the assembly head 4 can rotate between an assembly position as shown in Figures 5 and 6 and an exit position as shown in Figure 10 transform.

In the assembly position, the rear abutting surfaces 421 of the blocks 42 of the assembly head 4 can abut against the front abutting surfaces 258 of the protrusions 255 of the locking hole structure 25 . That is to say, the assembly head 4 is supported by the protrusions 255 through the clamping blocks 42, and the clamping blocks 42 are misaligned with the extension slots 257 of the clamping hole structure 25, so the assembly The head 4 cannot move backwards, but is locked against the seat wall 24 of the lamp seat 22 .

Rotate the light-emitting unit 3 in a clockwise forward direction D1, specifically, rotate the assembly shell 6, and then drive the assembly head 4 and the module seat 8 to rotate, so that the cards of the assembly head 4 can be rotated. The block 42 is displaced in the arc direction relative to the protrusions 255, thereby transforming the assembly head 4 to the withdrawn position as shown in FIG. 10 .

In the withdrawal position, the blocks 42 are respectively aligned with the extension slots 257 and are no longer limited by the protrusions 255, and since the extension slots 257 are larger than the blocks 42, the assembly head The head seat 41 and the retaining blocks 42 of 4 can withdraw from the assembly hole 256 and the extending grooves 257 of the retaining hole structure 25 backwards, and then detach from the lamp holder 22 .

In this way, when the light-emitting module 7 of one group of light-emitting units 3 fails, one group of light-emitting units 3 can be rotated to change the assembly head 4 to the exit position, and one group of light-emitting units can be 3 separate from the lamp housing unit 2, insert another set of new light-emitting units 3 and rotate in a reverse direction D2 opposite to the forward rotation direction D1, so that the assembly head 4 is changed from the withdrawal position to the assembly position , that is, the installation of a new group of the light emitting units 3 is completed. In this way, whenever one group of light-emitting units 3 fails, it is only necessary to replace the failed one group of light-emitting units 3 without scrapping the other group of light-emitting units 3 and the lamp housing unit 2 as a whole. The components are avoided from being wasted, so the present invention has the advantages of benzene saving and environmental protection.

In other embodiments of the present invention, only one light-emitting unit 3 can be included, and after the light-emitting unit 3 is damaged, since the light-emitting unit 3 can be replaced, the lamp housing unit 2 does not need to be scrapped, and it also has Advantages of cost saving and environmental protection.

Wherein, when the assembly head 4 rotates, the rear slopes 422 of the clamping blocks 42 of the assembly head 4 and the front slopes 259 of the projections 255 of the clamping hole structure 25 can facilitate the clamping The block 42 and the protruding blocks 255 move relative to each other in the arc direction, so that each rear abutment surface 421 abuts or disengages from a respective front abutment surface 258, which has the advantage of being easy to assemble and disassemble. As for the waterproof ring 51, it is squeezed and abutted between the ring wall section 252 of the clamping hole structure 25 and the ring seat 43 of the assembly head 4, and covers the ring seat 43 and the shoulder shell portion 62 of the assembly shell 6. The junction of the light-emitting unit 3 can avoid water ingress causing failure.

Referring to FIG. 11 , a second embodiment of the present invention is similar to the first embodiment, except that the light emitting unit 3 further includes a glue block 52 disposed in the tray space 811 of the module holder 8 . The rubber block 52 connects the positioning posts 44 of the assembly head 4, the positioning feet 45, the positioning blocks 82 of the module seat 8 (refer to FIG. 9 ) and the driving circuit board 91 of the driving module 9 ( Referring to Figure 9) glued together, each component can be further positioned, and has a waterproof effect. In manufacturing, the glue can be injected into the disk seat space of the module seat 8 through the first glue injection holes 431 of the ring seat 43 of the assembly head 4 and the second glue injection holes 621 of the shoulder shell portion 62 In 811, the glue block 52 is formed.

To sum up, the effect of the vehicle lamp device of the present invention is that: when the light emitting module 7 of the light emitting unit 3 is damaged and cannot emit light normally, the light emitting module 7 can be completely withdrawn together with the assembly head 4 and directly replaced with a A new light-emitting unit 3 is assembled, so that the whole car light device is not scrapped, so it can save expenses and be more environmentally friendly.

What is described above is only an embodiment of the present invention, and cannot limit the patent scope of the present invention, and the simple equivalent changes and modifications according to the patent scope of the present invention and the patent specification should also be included in the present invention. covered by the patent application.
