[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0031] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms “mounting”, “connection”, “connecting” should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, or electrical connection or can communicate with each other; can be directly connected, or indirectly connected through an intermediate medium, can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] The vehicle emblem assembly, vehicle emblem and vehicle lamp in the present application will be described in detail below with reference to the drawings and specific embodiments.

[0033] In the prior art, there is a gap between the illuminated part and the non-illuminated part of the car logo, and there is a light leakage phenomenon when the car logo is illuminated, and the car logo illumination effect is poor.

[0034] To solve the above technical problems, the application provides a car logo assembly, which comprises a light-transmitting part and a light-blocking part; the light-transmitting part is configured to conduct light, and the light-emitting side of the light-transmitting part is provided with a wedge-shaped groove, the wedge-shaped groove has a matching surface around the circumferential side of the X-axis direction, and the main light-emitting direction of the light-transmitting part is parallel to the X-axis direction; the light-blocking part has a crimping surface around the circumferential side of the X-axis direction, and the light-blocking part is embedded in the wedge-shaped groove so that the crimping surface is crimped on the matching surface. Details are described below.

[0035] Referring to Figure 1 , the car logo assembly comprises a light-transmitting part 10 and a light-blocking part 20; the light-transmitting part 10 is configured to conduct light, the light-emitting side of the light-transmitting part 10 is provided with a wedge-shaped groove 11, the wedge-shaped groove 11 has a matching surface 111 around the circumferential side of the X-axis direction, and the main light-emitting direction of the light-transmitting part 10 is parallel to the X-axis direction; the light-blocking part 20 has a crimping surface 21 around the circumferential side of the X-axis direction, and the light-blocking part 20 is embedded in the wedge-shaped groove 11 so that the crimping surface 21 is crimped on the matching surface 111.

[0036] The light-emitting side of the light-transmitting part 10 is provided with a wedge-shaped groove 11, the opening of the wedge-shaped groove 11 faces the light-emitting side of the light-transmitting part 10, and the wedge-shaped groove 11 is arranged outwardly, that is Figure 1 In the viewing angle, the distance between the upper and lower sidewalls of the wedge-shaped groove 11 gradually increases from left to right (the main light-emitting direction of the light-transmitting part 10); when the light-blocking part 20 needs to be embedded in the wedge-shaped groove 11, it is convenient for the light-blocking part 20 to enter the wedge-shaped groove 11, and the assembly efficiency is improved.

[0037] At the same time, the crimping surface 21 is crimped on the matching surface 111, so that the light-blocking part 20 can completely block the groove bottom of the wedge-shaped groove 11, and can avoid the gap between the light-blocking part 20 and the groove wall (the light-transmitting part 10) of the wedge-shaped groove 11, so as to avoid the light from the gap and cause light leakage.

[0038] It should be noted that the light-transmitting part 10 is made of light-transmitting material, and the light can enter the light-transmitting part 10 from the light-entering side of the light-transmitting part 10 and then exit from the light-emitting side of the light-transmitting part 10; the light-blocking part 20 is made of non-light-transmitting material and can block light.

[0039] It is worth mentioning that the light-blocking part 20 is embedded in the wedge-shaped groove 11, which can reduce the size of the car logo assembly in the X-axis direction, is conducive to the flat design of the car logo, reduces the occupation of space, and avoids the car logo being too protruding to affect the appearance.

[0040] Referring to Figure 6The wedge-shaped groove 11 is arranged in the middle region of the light-transmitting piece 10 on the light-emitting side, so that the edge of the light-emitting side of the light-transmitting piece 10 forms a ring-shaped light-emitting area 30.

[0041] By arranging the light-blocking piece 20, the middle region of the light-transmitting piece 10 is blocked, so that light can only be emitted from the edge of the light-transmitting piece 10 (the part of the light-emitting side of the light-transmitting piece 10 that is not blocked by the light-blocking piece 20), that is, light is emitted in the ring-shaped region around the light-blocking piece 20. When the logo is illuminated, the outline of the light-blocking piece 20 (the logo) is displayed, making the logo more three-dimensional and prominent, improving the design and aesthetic level of the logo, and only light is emitted from the edge of the light-blocking piece 20, avoiding large-area lighting and improving the comfort and visual effect of the logo illumination.

[0042] When the logo is illuminated, only light is emitted from the edge of the light-blocking piece 20, avoiding light pollution caused by the entire logo illumination. When the entire logo is illuminated (the entire exposed surface of the logo is illuminated, the same below), due to the large illumination area and high light intensity, the eyes may be irritated in a dark environment, which is not conducive to the safety of night driving and has poor visual effect, which is not conducive to the observation of the logo design. In addition, when the entire logo is illuminated, a large area needs to be illuminated, which is prone to uneven brightness, poor lighting effect, and requires more light sources (such as LED beads), increasing the use cost. More light sources require more layout space, which is not conducive to the design of the logo.

[0043] It should be noted that the ring-shaped light-emitting area 30, that is, the area that emits light when the logo is illuminated, is continuous, improving the aesthetic level when the logo is illuminated. The specific shape of the ring-shaped light-emitting area 30 is determined according to the specific design of the light-blocking piece 20, which is not limited here.

[0044] It is worth mentioning that when the light-transmitting piece 10 and the light-blocking piece 20 are arranged separately, the wedge-shaped groove 11 arranged on the light-emitting side of the light-transmitting piece 10 can facilitate the installation of the light-blocking piece 20, which only needs to be clamped in the wedge-shaped groove 11 without the need for additional positioning operations of the light-blocking piece 20, improving the assembly efficiency. At the same time, the size control of the light-emitting area 30 on the opposite sides of the light-blocking piece 20 can limit the size of the light-emitting area 30 in the Y-axis direction through the size of the wedge-shaped groove 11 to meet the design requirements of the logo.

[0045] In some embodiments, the surface of the light-emitting area 30 towards the light-emitting side of the light-transmitting piece 10 is flush with the surface of the light-blocking piece 20 towards the light-emitting side of the light-transmitting piece 10.

[0046] The surface of the light-emitting area 30 towards the light-emitting side of the light-transmitting piece 10 is flush with the surface of the light-blocking piece 20 towards the light-emitting side of the light-transmitting piece 10, that is, the right side surface of the logo is flat. Figure 1 The visual angle is flat; when the logo is not illuminated, the aesthetic level and visual effect are effectively improved.

[0047] In some embodiments, the light-emitting area 30 has a first light-emitting surface 31 and a second light-emitting surface 32. The first light-emitting surface 31 is arranged around the light-shielding member 20, and the second light-emitting surface 32 is arranged around the side of the first light-emitting surface 31 away from the light-shielding member 20. A reference straight line a parallel to the X-axis direction is used as a reference line, and the reference line passes through the connection between the first light-emitting surface 31 and the second light-emitting surface 32. The first light-emitting surface 31 and the second light-emitting surface 32 are respectively arranged on both sides of the reference line, and the distance between the second light-emitting surface 32 and the reference line in the Y-axis direction gradually decreases along the X-axis direction.

[0048] The first light-emitting surface 31 and the second light-emitting surface 32 are respectively set on both sides of the reference line, and the distance from the second light-emitting surface 32 to the reference line (in the Y-axis direction) gradually decreases along the X-axis direction. That is, the first light-emitting surface 31 and the second light-emitting surface 32 are set at an angle, so the light does not emerge from a flat surface. The light emitted from the first light-emitting surface 31 and the second light-emitting surface 32 will have more layers (in Figure 1 When viewed from the right, not only are there rays of light emitted along the X-axis, but also rays of light emitted at an angle to the X-axis, which enhances the three-dimensionality of the car logo and makes the logo illuminate well.

[0049] At the same time, when the car logo is lit, light is emitted from both the first light-emitting surface 31 and the second light-emitting surface 32; this increases the visible range, meaning that the car logo can be observed from multiple angles when it is lit.

[0050] It should be noted that in some embodiments, the second light-emitting surface 32 is inclined, which can guide water to the outside of the vehicle in situations such as rainy days or car washing. Figure 1 (Right side) This design prevents liquid from flowing into the car emblem (vehicle), thus extending the emblem's lifespan.

[0051] See Figure 4 The light-shielding member 20 also has a shaped surface 22 facing the light-emitting side of the light-transmitting member 10; the periphery of the shaped surface 22 abuts against the mating surface 111 of the wedge groove 11, so that the mating surface 111 forms a third light-emitting surface 1111 in the part of the shaped surface 22 away from the light-shielding member 20.

[0052] In this embodiment, the description is based on the annular light-emitting area 30 having a first light-emitting surface 31 and a second light-emitting surface 32. That is, a third light-emitting surface 1111 is provided on the side of the first light-emitting surface 31 away from the second light-emitting surface 32. The first light-emitting surface 31, the second light-emitting surface 32, and the third light-emitting surface 1111 face different directions. The light does not emerge from a flat surface, so the emitted light will be more layered, enhancing the three-dimensionality of the car logo and improving the lighting effect of the car logo. For a detailed analysis, please refer to the relevant discussion of the first light-emitting surface 31 and the second light-emitting surface 32. Similarly, it will not be repeated here.

[0053] It is worth mentioning that part of the light emitted from the third light-emitting surface 1111 can illuminate the modeling surface 22, thereby improving the recognition of the car logo at night.

[0054] It should be noted that the peripheral side of the modeling surface 22 abuts against the matching surface 111, i.e., the light shielding piece 20 is retracted inside the wedge-shaped groove 11, and the matching surface 111 is located on the right side of the modeling surface 22 (part of the Figure 4 viewing angle) to form the third light-emitting surface 1111; in some embodiments, the modeling surface 22 can also be arranged on the right side of the first light-emitting surface 31 (as shown), i.e., the light shielding piece 20 is protruded outside the wedge-shaped groove 11, and in this embodiment, the protruded part of the light shielding piece 20 can completely cover the opening of the wedge-shaped groove 11, and part of the light emitted from the first light-emitting surface 31 will be irradiated on the light shielding piece 20, which can be processed on the leaked part of the light shielding piece 20 to make the light irradiated on the leaked part of the light shielding piece 20 diffuse and reflect, thereby improving the lighting effect and visual effect of the car logo. Figure 5

[0055] Referring to Figure 1 , the reference plane λ perpendicular to the X-axis direction is taken as the reference surface, and the reference surface is arranged on the light-emitting side of the light-transmitting piece 10; the distance between the reference surface and the modeling surface 22 in the X-axis direction gradually increases along the Y-axis direction.

[0056] In this embodiment, the modeling surface 22 is arranged in an inclined manner, which can quickly guide the liquid to flow out under the use conditions of rainy days, car washing, etc., thereby avoiding the accumulation of liquid to affect the lighting effect of the car logo (the liquid has the effect of refraction on light, etc.), and also improving the service life of the car logo.

[0057] Referring to Figures 3-5 , the light-transmitting piece 10 and the light shielding piece 20 are integrally arranged by double-color injection molding processing; the light shielding piece 20 has a shielding part 23 and a mounting part 24, the mounting part 24 is arranged on the surface of the shielding part 23 facing the light-incident side of the light-transmitting piece 10, and the end of the mounting part 24 away from the shielding part 23 penetrates through the light-transmitting piece 10, and the pressing surface 21 is arranged on the shielding part 23; the normal projection of the mounting part 24 on the reference plane λ perpendicular to the X-axis direction is located within the normal projection of the shielding part 23 on the reference plane λ.

[0058] In this embodiment, the light-transmitting piece 10 and the light shielding piece 20 are formed by injection molding, and are integrally arranged, which is beneficial to improve the control of the relative position between the light-transmitting piece 10 and the light shielding piece 20, improve the processing precision, and further improve the lighting effect of the car logo.

[0059] ​The mounting portion 24 is arranged at one side of the shielding portion 23, and a normal projection of the mounting portion 24 on the reference plane is located within a normal projection of the shielding portion 23 on the reference plane, that is, the mounting portion 24 does not shield the light required to be emitted from the light-emitting area 30 when the logo is illuminated; meanwhile, an end of the mounting portion 24 away from the shielding portion 23 penetrates the light-transmitting piece 10, which is beneficial to injection molding.

[0060] It is worth mentioning that, by arranging the shielding portion 23 and the mounting portion 24, the light-transmitting piece 10 is correspondingly provided with a mounting through hole 12 for accommodating the mounting portion 24; in some embodiments, when the light shielding piece 20 and the light-transmitting piece 10 are arranged in a split manner, the above structure increases the contact area between the light-transmitting piece 10 and the light shielding piece 20, and improves the stability of the connection therebetween.

[0061] In some embodiments, the light shielding piece 20 can be color injection molding, and after injection molding is completed, the light shielding piece 20 has a metallic luster, which improves the static (unlit) visual effect of the logo.

[0062] Referring to Figure 1 , the light-transmitting piece 10 and the light shielding piece 20 are arranged in a split manner; the wedge-shaped groove 11 is provided with a flash groove 13; the surface of the light shielding piece 20 facing the light-incoming side of the light-transmitting piece 10 is provided with a welding portion 25; the light shielding piece 20 is connected to the wedge-shaped groove 11 through the welding portion 25, and the flash groove 13 is configured to accommodate the welding portion 25 after welding melting.

[0063] In this embodiment, the connection and mounting between the light shielding piece 20 and the light-transmitting piece 10 are achieved by ultrasonic welding, and the welding portion 25 can be accommodated in the flash groove 13 after welding melting, so that the welding portion 25 after melting does not enter the wedge-shaped groove 11 to affect the mounting of the light shielding piece 20 in the wedge-shaped groove 11.

[0064] The shape of the flash groove 13 is not specifically limited in this embodiment, and can be an arc-shaped groove larger than a semicircle, so that the welding portion 25 after melting can also be clamped in the arc-shaped groove, which is beneficial to the reliable connection between the light shielding piece 20 and the light-transmitting piece 10. In some embodiments, the flash groove 13 can also be arranged in other forms, which will not be described here.

[0065] Similarly, in this embodiment, the surface (modeling surface 22) of the light shielding piece 20 facing the light-emitting side of the light-transmitting piece 10 can be formed with a metal surface layer by hot stamping, which improves the static (unlit) visual effect of the logo; in some embodiments, the surface of the light shielding piece 20 can also be plated with chromium to form a metal layer, which also improves the static visual effect of the logo, but is not limited thereto.

[0066] It should be noted that the welding portion 25 for ultrasonic welding cannot be plated with chromium, which can affect ultrasonic welding. The welding portion 25 can be coated with medicinal water or other methods to avoid plating on the welding portion 25. In some embodiments, the welding portion 23 can also be welded by laser welding, which is not limited thereto.

[0067] In some embodiments, the light shielding piece 20 can also be pasted in the wedge-shaped groove 11 by pasting, such as Figure 3 as shown, pasted by double-sided tape 40.

[0068] On the other hand, the application also relates to a car logo, which comprises any of the car logo assemblies described above, and further comprises a mounting piece 50 arranged on the light entrance side of the light-transmitting piece 10.

[0069] On the other hand, the application also relates to a car lamp, which comprises the car logo described above.

[0070] The technical scheme provided by the embodiments of the application aims to provide a wedge-shaped groove 11 on the light exit side of the light-transmitting piece 10, the opening of the wedge-shaped groove 11 faces the light exit side of the light-transmitting piece 10, and the wedge-shaped groove 11 is arranged outwardly. When the light shielding piece 20 needs to be embedded in the wedge-shaped groove 11, it is convenient for the light shielding piece 20 to enter the wedge-shaped groove 11, which improves the assembly efficiency. At the same time, the pressure contact surface 21 is pressure-contacted on the matching surface 111, so that the light shielding piece 20 can completely shield the groove bottom of the wedge-shaped groove 11, and can avoid the gap between the light shielding piece 20 and the groove wall (the light-transmitting piece 10) of the wedge-shaped groove 11, thereby avoiding the light from the gap.
