[0019] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] refer to Figure 1-Figure 4, a vehicle logo structure with a luminous function provided by the present invention comprises a bottom shell member 1 and a top shell member 2 detachably connected to the bottom shell member 1, that is, a plurality of fixed undercuts 15 are evenly arranged along the circumference of the upper end surface of the bottom shell member 1, and a avoidance hole 16 for the fixed undercut 15 to pass through is arranged at a position corresponding to the fixed undercut 15 on the top shell member 2, and a fixing block 17 cooperating with the fixed undercut 15 is arranged on the inner wall of the avoidance hole 16 away from the center point of the top shell member 2, and the fixing method of this structure facilitates the assembly of the bottom shell member 1 and the top shell member 2 together, and also facilitates installation and disassembly. The thickness from the upper end surface of the fixing block 17 to the bottom end surface of the avoidance hole 16 is less than the depth of the avoidance hole 16, and the upper end surface of the fixing block 17 and the inner wall of the avoidance hole 16 form a limiting step surface 18 cooperating with the fixed undercut 15, and the setting of this structure enables the fixed undercut 15 to be completely embedded in the avoidance hole 16, ensuring the flatness of the upper end surface of the top shell member 2, and improving the aesthetics of this vehicle logo structure.

[0021] refer to Figure 1-Figure 3 The upper end surface of the top shell 2 is provided with a car logo 3 consisting of text strokes or graphic lines protruding from the upper end surface of the top shell 2. The top shell 2 and the car logo 3 are integrally formed. The integral forming setting facilitates the processing of the car logo structure and has a high overall strength. The top shell 2 and the car logo 3 are made of the same material and are both made of light-transmitting materials, that is, the top shell 2 and the car logo 3 are both made of PC material. The top shell 2 and the car logo 3 made of PC material have good light transmittance. The upper end surface of the car logo 3 is coated with a coating, and the coating is gold or silver. When the car logo is not luminous, the car logo 3 appears gold or silver under the effect of the coating. When the car logo is luminous, the coating color disappears and the car logo is in a luminous state.

[0022] refer to Figure 5 and Figure 6, the hollow area of ​​the car logo 3 is provided with a sunshade 4, which is detachably connected to the hollow area through a connector 19. The sunshade 4 is made of TPO soft rubber material and is black or gray in color. The sunshade 4 has good light shielding performance. The top shell 2 is located outside the car logo 3 and is installed on the car body, and the car logo is fixed on the top shell 2 through the car fixed end cover. At this time, it also plays a light shielding role under the action of the car fixed end cover. When the car logo is lit, the sunshade 4 and the car fixed end cover ensure that only the car logo 3 is lit. The connecting member 19 includes a connecting column 191 vertically arranged at the bottom end of the sunshade 7 and a stopper 192 arranged at the bottom end of the connecting column 191. A connecting hole 24 for the connecting column 191 to pass through is arranged at a position corresponding to the connecting column 191 on the top shell 2. The outer diameter of the stopper 192 is larger than the inner diameter of the connecting hole 24. Under the action of the connecting column 191 and the stopper 192, the sunshade 4 is conveniently fixed on the top shell 2, and the sunshade 4 is not easy to move up and down. The area in the top shell 2 located at the stopper 192 is hollow, which can reduce the overall weight of the top shell 2.

[0023] refer to Figure 5 and Figure 7 The thickness of the sunshade 4 is the same as that of the car logo 3, and the side of the car logo 3 can be completely blocked. When the car logo 3 is lit, only the upper end surface of the car logo 3 is guaranteed to be lit, so as to avoid the light source from being emitted from the side of the car logo 3 and causing visual fatigue to the user. At least one anti-light-transmitting protrusion 10 is provided on the side where the sunshade 4 and the car logo 3 are in contact. The color of the anti-light-transmitting protrusion 10 is black or gray, and the anti-light-transmitting protrusion 10 is also made of TPO soft rubber material. The anti-light-transmitting protrusion 10 improves the tightness between the sunshade 4 and the side of the car logo 3, so that the sunshade 4 is firmly fixed in the hollow area, and at the same time, light leakage between the sunshade 4 and the car logo 3 is prevented.

[0024] refer to Figure 2 , Figure 5 , Fig. 9 and Fig.10There is a containing space 5 between the bottom shell 1 and the top shell 2. The top of the containing space 5 is connected to the hollow area in the top shell 2. A light-emitting component is arranged in the containing space 5. The light emitted by the light-emitting component is used to illuminate the car logo 3, so that the car logo 3 is illuminated to realize visual identification. The light-emitting component includes a light source emitting component and a light guide plate 7 arranged on the upper end surface of the light source emitting component. The light source emitting component includes a circuit board 6 installed on the bottom shell 1 and a plurality of light sources 8 arranged on the circuit board 6. Among them, a power plug 25 for supplying power to the circuit board 6 is arranged on the radial outer edge surface. The power plug 25 is located at the bottom end of the longitudinal warp of the circuit board 6. The top shell 2 and the bottom shell 1 are both provided with an embedding portion 26 at a position corresponding to the power plug 25. After being buckled, the embedding portions 26 on the top shell 2 and the bottom shell 1 cooperate to form a placement position for placing the power plug 25. By arranging the power plug 25 at the bottom end of the longitudinal warp of the circuit board 6, it is convenient to connect the power plug 25 with the external power supply, and it also plays a positioning role, so that the circuit board 6 can be easily and quickly installed in the placement position; multiple light sources 8 are distributed below the shading plate 4, and the lower end surface of the light guide plate 7 is provided with an embedding groove 9 for embedding the light source 8 at a position corresponding to the light source 8; wherein the multiple light sources 8 are all side-emitting lamp beads, wherein at least one side-emitting lamp bead faces the inner side of the light guide plate 7, wherein the other side-emitting lamp beads face the outer side of the light guide plate 7, and the light source emitted by the side-emitting lamp bead facing the outer side of the light guide plate 7 is not necessarily emitted along the radial direction of the light guide plate 7, but can be emitted obliquely. The lower end surface of the light guide plate 7 and located in the internal area of ​​the car logo 3 are provided with multiple light-distributing grooves 14 cooperating with the light source 8, and the light-distributing grooves 14 are used to refract the light emitted by the side-emitting lamp bead onto the car logo 3, so that the car logo 3 emits light to achieve visual identification. The cross section of the light-evening groove 14 is convexly semicircular. The light-evening groove 14 of this structure has a good refraction effect and can refract the light emitted by the light source 8 to the car logo 3 to evenly evenly evenly distribute the light, thereby improving the luminous effect of the car logo 3.

[0025] refer to Fig. 9 and Fig.11 The radial outer edge of the circuit board 6 is provided with a plurality of limiting notches 12 along its circumference, and the bottom shell 1 is provided with limiting protrusions 13 that cooperate with the limiting notches 12. Figure 2The light guide plate 7 is embedded in the top shell 2. A plurality of fixing protrusions 20 are evenly arranged on the radial outer edge surface of the light guide plate 7 along its circumference. A limiting groove (not shown in the figure) that cooperates with the fixing protrusions 20 is arranged in the top shell 2. When the light-emitting component is installed in the accommodating space 5, the limiting protrusions 13 cooperate with the limiting notches 12, and the fixing protrusions 20 and the limiting grooves cooperate to limit and fix the circuit board 6 and the light guide plate 7, thereby preventing the light-emitting component from rotating in the accommodating space 5, thereby improving the stability and firmness of the light-emitting component in the accommodating space 5. Among them, the number of the fixing protrusions 20 in the present invention is two, and they are unevenly distributed on the outer edge surface of the light guide plate 7. The sizes of the two fixing protrusions 20 are different, and the size of the limiting groove is adapted to the size of the corresponding fixing protrusion 20. By setting the two fixing protrusions 20 to different sizes and distributing them unevenly on the light guide plate 7, a positioning function is also played. During installation, it is not easy to install the light guide plate 7 upside down, thereby achieving a quick installation effect.

[0026] refer to Figure 5 and Figure 8 A limiting column 22 for pressing the light guide plate 7 is arranged on the bottom end surface of the top shell 2 and located in the accommodating space 5. When the light-emitting component is arranged in the accommodating space 5, the limiting column 22 can limit the light-emitting component in the longitudinal direction, prevent the light-emitting component from moving longitudinally, and improve the stability and firmness of the light-emitting component in the accommodating space 5. In addition, the diameter of the accommodating space 5 in the top shell 2 gradually decreases from bottom to top. Through the arrangement of this structure, when the light guide plate 7 is embedded in the top shell 2, the light guide plate 7 can be limited longitudinally and transversely, thereby preventing the light guide plate 7 from rotating or moving transversely or longitudinally, and further improving the firmness of the vehicle logo structure.

[0027] refer to Figure 5 and Figure 8 A matte coating 11 is provided on the outer edge surface of the light guide plate 7 in the radial direction. The matte coating 11 is a sand coating layer or is processed by a spark discharge machining process. The matte coating 11 blocks the light source emitted by the light source 8, ensuring that the emitted light source is only refracted to the car logo 3 through the light-homogenizing groove 14 or reflected to the car logo 3 through the matte coating 11, thereby improving the light-homogenizing effect.

[0028] refer to Figure 5 The bottom shell 1 is located in the center of the light source emitting element and bulges downward to form a buffer space 23. When the outer bottom end of the bottom shell 1 of the vehicle logo structure is subjected to external impact, the buffer space 23 is provided to buffer the light emitting component in the accommodating space 5, thereby protecting the light emitting component.

[0029] refer to Figure 2 A plurality of support protrusions 27 for supporting the light source emitting element are arranged on the bottom end surface of the bottom shell 1 and located in the accommodating space 5 along the circumference of the buffer space 23. The support protrusions 27 support the light source emitting element placed in the bottom shell 1, thereby improving the stability and firmness of the light source emitting element.

[0030] In summary: the car logo structure of this structure is easy and quick to assemble, and has a simple structure, saving time and effort; in addition, the light source 8 in this car logo structure is distributed in the area where the light guide plate is located below the light shielding plate 4, that is, the light source 8 is concentrated in the area close to the center point of the light guide plate 7. Under the condition that the car logo 3 can emit light normally, the size of the light guide plate 7 can be reduced, the overall weight of the light guide plate 7 can be greatly reduced, and the space occupied by the light-emitting component in the accommodating space 5 can be reduced, thereby improving the strength of the car logo. In addition, by setting the light-evening groove 14 in the area of ​​the car logo 3, when the light source emitted by the light source 8 is reflected to the car logo 3 through the light-evening groove 14, the light-evening of this structure is more uniform, which can improve the lighting effect of the car logo 3.
