[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0026] Example 1:

[0027] like Figure 3-Figure 7 As shown, a vehicle logo lamp mainly includes a lamp housing 1, a mask 2 and a PCBA 3 integrated with a plurality of LED lamp beads 31, wherein the mask 2 covers the lamp housing 1, and the lamp housing 1 and the mask 2 together form a component installation cavity, and the PCBA 3 is installed in the component installation cavity.

[0028] In this embodiment, the mask 2 includes a mask body 21 and an annular shielding portion 22. The mask body 21 and the annular shielding portion 22 are integrally formed through a two-color injection molding process, wherein the mask body 21 is made of translucent plastic material and the annular shielding portion 22 is made of shading plastic material, which has good processability and high structural strength.

[0029] Furthermore, the mask body 21 is made of a milky white, light-transmitting plastic material, which not only provides excellent light transmission but also shields the internal components, making the internal PCBA 3 invisible from the outside, thus maintaining the lamp's aesthetic appearance. The annular shielding portion 22 is made of a black, light-blocking plastic material, which not only provides excellent light-blocking effect but also creates a sharp contrast with the milky white mask body 21, enhancing the lamp's aesthetic appearance.

[0030] The circumferential outer edge of the lamp housing 1 has a circle of circular welding step surface 111, the mask body 21 includes a light emitting panel 211 and an annular connecting portion 212 extending from the circumferential outer edge of the light emitting panel 211 to the welding step surface 111, and the light-emitting surface of each LED lamp bead 31 faces the light emitting panel 211. The light emitting panel 211 is provided with a car logo graphic 211a to ensure the lighting effect of the car logo light.

[0031] The outer edge of the annular connecting portion 212 away from the light emitting panel 211 is fixedly connected to the welding step surface 111 through a welding process. In this embodiment, the connection between the annular connecting portion 212 and the welding step surface 111 is preferably made by vibration friction welding to ensure the sealing performance of the lamp.

[0032] See Figure 5 and Figure 7 The inner edge of the welding step surface 111 protrudes to form a circle of inner ribs 12 extending toward the light output panel 211. The inner ribs 12 can effectively block the inner welding slag generated by welding, ensuring the lighting effect of the lamp.

[0033] Furthermore, the lamp housing 1 has a lamp trough 13 that is compatible with the PCBA3. The PCBA3 is installed in the lamp trough 13, ensuring the reliability of the installation of the PCBA3. At the same time, a circle of support ribs 11 is protruded on the circumferential outer wall of the lamp trough 13. The side surface of the support rib 11 close to the annular connecting portion 212 is a welding step surface 111, which ensures the connection strength between the lamp housing 1 and the lampshade 2.

[0034] Furthermore, a plurality of circuit board positioning pins 15 are provided at the bottom of the lamp trough 13, and circuit board positioning holes corresponding to each circuit board positioning pin 15 are opened on the PCBA3. Each circuit board positioning pin 15 passes through the corresponding circuit board positioning hole, which not only ensures the reliability of the installation of the PCBA3, but also plays a role in preventing errors in the installation of the PCBA3.

[0035] See Figure 4-Figure 6 The annular shielding portion 22 is annular and covers the outside of the annular connecting portion 212, and the outer edge of the annular shielding portion 22 on one side away from the light emitting panel 211 shields the connection between the annular connecting portion 212 and the welding step surface 111. The annular shielding portion 22 can not only enrich the appearance of the lamp, but also effectively block the outer welding slag generated by welding, play a role in covering up the ugliness, and ensure the appearance of the lamp. At the same time, compared with the existing addition of special covering parts or adding shielding structures on the body parts, its cost is lower.

[0036] In this embodiment, the outer edge of the annular shielding portion 22 away from the light emitting panel 211 extends beyond the supporting rib 11 to ensure complete shielding.

[0037] See Figure 3 and Figure 5 The outer edge of the annular shielding portion 22 away from the welding step surface 111 is bent inward to form a ring 221 that covers the outer edge of the light output panel 211 in an annular shape, so as to enhance the overall appearance of the lamp.

[0038] In this embodiment, the car logo pattern 211a is adhered to the outer surface of the light emitting panel 211, which is simple and reliable. Usually, the car logo pattern 211a is adhered to the outer surface of the light emitting panel 211 by adhesive, which is efficient and does not cause glue overflow.

[0039] Example 2:

[0040] See Figure 1 and Figure 2, an unobstructed installation structure of a vehicle logo light, a body part 4 and a vehicle logo light of Example 1, a vehicle logo light mounting base 41 is provided on the body part 4, the lamp housing 1 is installed on the vehicle logo light mounting base 41, and the mask 2 is completely exposed outside the body part 4.

[0041] A plurality of positioning pins 13 and mounting clips 14 are provided on the surface of the side of the lamp housing 1 away from the mask 2. The vehicle logo light mounting seat 41 is provided with positioning holes 411 respectively adapted to the corresponding positioning pins 13 and clamping seats 412 respectively adapted to the corresponding mounting clips 14. Each positioning pin 13 is respectively embedded in the corresponding positioning hole 411, and each mounting clip 14 is respectively inserted into the corresponding clamping seat 412, which not only ensures the reliability of the installation of the vehicle logo light, but also facilitates the disassembly and replacement of the vehicle logo light after damage.

[0042] Furthermore, the vehicle logo light and the vehicle body part 4 are locked by bolts and nuts, which further improves the reliability of the vehicle logo light installation.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
