[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1-Figure 5 As shown, in this example, the automotive DLP micro-projection lamp includes a DLP optical subassembly 5, a mask 2, a radiator 6, and a mounting frame 1, wherein the DLP optical subassembly 5 is purchased directly from the market, such as including an optical module, a drive and heat dissipation module, wherein the optical module includes an LED light source, a DMD chip, and a lens group, and light is emitted from the light source to form a picture or video through the DMD chip, and then magnified and projected through the lens group. The DLP optical subassembly 5 is installed in a sealed space surrounded by the mask 2 and the radiator 6, and the projection end of the DLP optical subassembly 5 corresponds to the transparent part of the mask 2.

[0027] The mounting frame 1 includes a plate body 10 and a support 11. The support 11 is distributed in a triangular shape on the front of the plate body 10. The support 11 and the plate body 10 are integrally formed, such as PC material. The mask 2 includes a box body 21 and an end plate 24. The end plate 24 is integrally formed at the peripheral wall of the box body 21 corresponding to the support 11, such as Figure 4 In the state shown, end plates 24 are formed on the left side, right side and rear side of the peripheral wall at the box opening of the box body 21. The end plates 24 are fixed to the adjacent pillars 11, such as by snap fastening. Figure 4 As shown, the end plate 24 is fixed to the pillar 11 by screws 3 or the like. A positioning column 14, such as a cross column, can be optionally formed on the pillar 11 corresponding to the left and right sides of the box body 21, and a positioning hole is formed on the corresponding end plate 24. During installation, the positioning column 1 is inserted into the positioning hole to complete pre-positioning, and then the end plate and the pillar can be fixed as a whole by screws or the like.

[0028] In this example, the height of the support 11 corresponding to the rear side of the box body 21 is lower than the height of the support corresponding to the left and right sides of the box body 21. This design allows the box body to be fixed on the mounting frame in an inclined state. Figure 1 , Figure 4As shown, a through hole is formed at the end face of the box body corresponding to the box opening and a light-transmitting sheet 23 is fixed at the hole. Of course, the light-transmitting sheet can also be integrally formed, with the light-transmitting sheet as the transparent part. When the mask is tilted, the light-transmitting sheet 23 is directed to the outside of the mounting frame 1, so that the projection emitted by the DLP optical machine subassembly is emitted from the light-transmitting sheet to a position outside the mounting frame to avoid being affected by the mounting frame. For the integrally formed light-transmitting sheet structure, such as a two-color PC material, the light-transmitting sheet is formed with transparent PC, and the rest of the box body is formed with black PC.

[0029] As for the radiator, the radiator 6 is fixed at the box opening of the box body 21. The radiator 6 includes a plate body 61 and a heat dissipation grille 62 formed at the front of the plate body 61. The radiator is made of AL material. The plate body 61 is fixed at the box opening of the box body 21, such as by fitting, snap-fitting or screws. Figure 4 As shown, it is preferred to form a groove at the end surface of the box mouth, and place a sealing gasket 4 in the groove. When the radiator is installed, the bottom surface of the second plate body 61 fits with the sealing gasket 4, which helps to improve the sealing performance.

[0030] In order to facilitate the docking of the mounting frame with the vehicle doors, taillights, etc., in this example, a mounting hole 13 and a second positioning column 12 are formed on the other side of the mounting frame 1 opposite to the side where the mask 2 is located. For example, a plurality of through holes are formed at intervals around the bottom surface of the plate body 1 in the mounting frame to form a mounting hole, and a second positioning column, such as a cross column, is formed at intervals in the middle of the bottom surface of the plate body 1. The positioning column 2 is used for pre-positioning, and screws are connected through the mounting holes to facilitate installation.

[0031] When in use, the projection lamp can display the personalized dynamic information of the vehicle, realize information interaction between the vehicle and the user, and improve the user experience.

[0032] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
