Description

Technical Field

[0001] This utility model relates to the field of lamp cover technology, and in particular to a rear light cover, a rear light assembly, and a vehicle. Background Technology

[0002] Currently, existing rear combination lights integrate three types of lights: rear position lights, brake lights, and rear turn signals. To meet regulatory requirements, the rear position lights need to be set to red, the brake lights to red, and the turn signals to amber. The optical systems of these three lighting functions produce two colors of light through the lens, thus requiring two different colored lenses: one red and one white. A black lens is also needed to prevent light leakage. This necessitates the production of three different colored lenses, significantly increasing the production cost. Furthermore, the installation of these three lenses requires bolts and screws to connect them, making the installation process overly complex.

[0003] Therefore, it is necessary to provide a new taillight cover, taillight assembly, and vehicle to solve the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this utility model is to propose a rear light cover, a rear light assembly, and a vehicle, aiming to improve the technical problems of high production cost and complex installation of rear light covers in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a rear light cover is provided, comprising:

[0006] A light-shielding assembly, comprising a first light-shielding member, a second light-shielding member, and a third light-shielding member, wherein the first light-shielding member, the second light-shielding member, and the third light-shielding member are spaced apart.

[0007] A red light-transmitting component, the two ends of which are respectively connected to the first light-shielding component and the second light-shielding component, the red light-transmitting component, the first light-shielding component and the second light-shielding component cooperate to form a first light-transmitting area for covering the position light and the brake light;

[0008] A white light-transmitting component, the two ends of which are respectively connected to the second light-shielding component and the third light-shielding component, the white light-transmitting component, the second light-shielding component and the third light-shielding component cooperate to form a second light-transmitting area for covering the turn signal.

[0009] In one embodiment, the light-shielding component, the red light-transmitting component, and the white light-transmitting component are integrally formed by injection molding; wherein, the first light-shielding component, the second light-shielding component, and the third light-shielding component are formed by a first injection molding, and the red light-transmitting component and the white light-transmitting component are formed by a second injection molding.

[0010] In one embodiment, the first light-shielding member, the second light-shielding member, and the third light-shielding member are all black.

[0011] In one embodiment, the contact surfaces of the first light-shielding member and the second light-shielding member with the red light-transmitting member are both provided with a stepped interlocking structure.

[0012] In one embodiment, the first light-shielding member, the second light-shielding member, and the third light-shielding member are all colorless plexiglass layers mixed with black dye.

[0013] In one embodiment, the red light-transmitting element is a colorless plexiglass layer mixed with a red dye.

[0014] In one embodiment, the white light-transmitting element is a colorless plexiglass layer mixed with a white dye.

[0015] In one embodiment, there are two red light-transmitting elements, one of which is connected at both ends to the first light-shielding element and the second light-shielding element, respectively, and the other red light-transmitting element is installed on the third light-shielding element.

[0016] According to another aspect of this utility model, this utility model also provides a rear light assembly, including a lamp housing, two thick-walled members, two lamp plates, and the aforementioned rear light cover. The rear light cover is installed on the lamp housing, and the rear light cover and the lamp housing cooperate to form a placement cavity. The two thick-walled members are spaced apart in the placement cavity, and the two lamp plates are respectively installed on the two thick-walled members. Each of the two lamp plates is provided with a light source. The light source is used to shine light into the thick-walled members and out of the thick-walled members through the rear light cover.

[0017] According to another aspect of the present invention, the present invention also provides a vehicle including a rear light assembly as described above, the rear light assembly being mounted at the rear of the vehicle.

[0018] In the above solution, the rear light cover includes a light-shielding component, a red light-transmitting component, and a white light-transmitting component. The light-shielding component includes a first light-shielding component, a second light-shielding component, and a third light-shielding component, which are spaced apart. The two ends of the red light-transmitting component are integrally connected to the first light-shielding component and the second light-shielding component, respectively. The red light-transmitting component, the first light-shielding component, and the second light-shielding component cooperate to form a first light-transmitting area for covering the position lights and brake lights. The two ends of the white light-transmitting component are integrally connected to the second light-shielding component and the third light-shielding component, respectively. The white light-transmitting component, the second light-shielding component, and the third light-shielding component cooperate to form a second light-transmitting area for covering the turn lights. Specifically, a first light-shielding component, a second light-shielding component, and a third light-shielding component are spaced apart. The two ends of a red light-transmitting component are integrally connected to the first and second light-shielding components, respectively. The red light-transmitting component, the first light-shielding component, and the second light-shielding component work together to form a first light-transmitting area. The light emitted by the position lights and brake lights passes through this first light-transmitting area and is then emitted from the red light-transmitting component, thus emitting red light. The two ends of a white light-transmitting component are integrally connected to the second and third light-shielding components, respectively. The white light-transmitting component, the second light-shielding component, and the third light-shielding component work together to form a second light-transmitting area. The light emitted by the turn lights passes through this second light-transmitting area and is then emitted from the white light-transmitting component, thus emitting amber light. In this way, the light emitted by the turn lights, position lights, and brake lights all meet regulatory requirements. The three light-shielding components can separate light areas with different functions and prevent mutual interference between light sources. Compared to existing technologies that produce three different colored lamp covers separately, this invention reduces production costs by molding three light-shielding components, a white light-transmitting component, and a red light-transmitting component into one piece. Furthermore, this structure simplifies installation by simply placing the rear light cover over the turn signal, position light, and brake light. Attached Figure Description

[0032] To achieve the above objectives, please refer to Figures 1 to 5This utility model proposes a rear light cover 100, including a light-shielding component 1, a red light-transmitting component 2, and a white light-transmitting component 3. The light-shielding component 1 includes a first light-shielding component 11, a second light-shielding component 12, and a third light-shielding component 13, which are spaced apart. The two ends of the red light-transmitting component 2 are integrally connected to the first light-shielding component 11 and the second light-shielding component 12, respectively. The red light-transmitting component 2, the first light-shielding component 11, and the second light-shielding component 12 cooperate to form a first light-transmitting area 4 for covering the position light and the brake light. The two ends of the white light-transmitting component 3 are integrally connected to the second light-shielding component 12 and the third light-shielding component 13, respectively. The white light-transmitting component 3, the second light-shielding component 12, and the third light-shielding component 13 cooperate to form a second light-transmitting area 5 for covering the turn light. Specifically, the first light-shielding member 11, the second light-shielding member 12, and the third light-shielding member 13 are spaced apart. The two ends of the red light-transmitting member 2 are integrally connected to the first light-shielding member 11 and the second light-shielding member 12, respectively. The red light-transmitting member 2, the first light-shielding member 11, and the second light-shielding member 12 work together to form the first light-transmitting area 4. The light emitted by the position lights and brake lights passes through the first light-transmitting area 4 and then shines out from the red light-transmitting member 2, thus emitting red light. The two ends of the white light-transmitting member 3 are integrally connected to the second light-shielding member 12 and the third light-shielding member 13, respectively. The white light-transmitting member 3, the second light-shielding member 12, and the third light-shielding member 13 work together to form the second light-transmitting area 5. The light emitted by the turn lights passes through the second light-transmitting area 5 and then shines out from the white light-transmitting member 3, thus emitting amber light. In this way, the light emitted by the turn lights, position lights, and brake lights can all meet the regulatory requirements. The three light-shielding members can separate the lighting areas with different functions and prevent mutual interference between the lights. Compared to the existing technology that produces three different colored lamp covers separately, this embodiment reduces the production cost of the lamp cover by integrally molding three light-shielding parts, a white light-transmitting part 3 and a red light-transmitting part 2. Moreover, this structure simplifies the installation process by simply placing the rear light cover 100 directly over the turn signal, position light and brake light.

[0033] In one embodiment, the light-shielding component 1, the red light-transmitting component 2, and the white light-transmitting component 3 are integrally formed by injection molding; wherein, the first light-shielding component 11, the second light-shielding component 12, and the third light-shielding component 13 are formed by a first injection molding, and the red light-transmitting component 2 and the white light-transmitting component 3 are formed by a second injection molding. Multiple components are injection molded twice in one mold, which reduces the number of molds required, thereby further reducing the production cost of the lampshade. During the second injection molding, the subsequently injected material will wrap around or embed in the structure formed in the first molding, forming a stronger physical connection; and the overall sealing performance is strong, which helps to improve the protection level of the lamp.

[0034] In one embodiment, the first light-shielding member 11, the second light-shielding member 12, and the third light-shielding member 13 are all black. Black materials have a strong absorption capacity for visible light, which can effectively reduce stray light reflection and crosstalk; thus, the light emitted by the position lights, brake lights, and turn signals can be emitted from the corresponding areas.

[0035] Please see Figure 3 In one embodiment, the contact surfaces of the first light-shielding member 11 and the second light-shielding member 12 with the red light-transmitting member 2 are both provided with stepped interlocking structures 6. During two-color or multi-color injection molding, the pre-designed interlocking structures can guide the flow direction of the molten plastic, ensuring that the material can accurately fill the predetermined position during the second injection, thus improving molding quality. Simultaneously, it can also enhance the bonding tightness between different materials, reducing delamination or peeling phenomena that may occur due to differences in thermal expansion coefficients.

[0036] In one embodiment, the first light-shielding element 11, the second light-shielding element 12, and the third light-shielding element 13 are all colorless acrylic glass layers mixed with a black dye. Using colorless acrylic glass enables the light-shielding elements to have good mechanical strength, weather resistance, and dimensional stability; and after the addition of the black dye turns the acrylic glass black, it can still maintain its original processing performance and aging resistance.

[0037] In one embodiment, the red light-transmitting element 2 is a colorless plexiglass layer mixed with a red dye. Using colorless plexiglass enables the red light-transmitting element 2 to have good mechanical strength, weather resistance, and dimensional stability; and after the addition of the red dye, even after the plexiglass turns red, it can still maintain its original processing performance and aging resistance.

[0038] In one embodiment, the white light-transmitting element 3 is a colorless acrylic glass layer mixed with a white dye. Using colorless acrylic glass enables the white light-transmitting element 3 to have good mechanical strength, weather resistance, and dimensional stability; and after adding the white dye to turn the acrylic glass white, it can still maintain its original processing performance and aging resistance.

[0039] In one embodiment, there are two red light-transmitting elements 2. One red light-transmitting element 2 is connected at both ends to the first light-shielding element 11 and the second light-shielding element 12, respectively, while the other red light-transmitting element 2 is installed on the third light-shielding element 13. By setting up such a structure, the appearance of the lampshade will become red, white, and red arranged sequentially from top to bottom. This symmetrical color distribution will make the appearance of the lampshade more aesthetically pleasing.

[0040] According to another aspect of this utility model, please refer to Figure 6This utility model also provides a rear light assembly 200, including a lamp housing 201, two thick-walled members 202, two lamp panels 203, and the aforementioned rear light cover 100. The rear light cover 100 is installed on the lamp housing 201, and the rear light cover 100 and the lamp housing 201 cooperate to form a placement cavity 204. The two thick-walled members 202 are spaced apart in the placement cavity 204, and the two lamp panels 203 are respectively installed on the two thick-walled members 202. Each of the two lamp panels 203 is provided with a light source. The light source is used to shine light into the thick-walled members 202 and out of the thick-walled members 202 and through the rear light cover 100. The light emitted from the light source on the lower light panel 203 enters the corresponding thick-walled member 202, then exits from the thick-walled member 202 and continues to pass through the white light-transmitting member 3 on the rear light cover 100, thus emitting amber light; the light emitted from the light source on the upper light panel 203 enters the corresponding thick-walled member 202, then exits from the thick-walled member 202 and continues to pass through the red light-transmitting member 2 on the rear light cover 100, thus emitting red light. The black light shield isolates the light emitted from the two light panels 203, ensuring that the light exits from the corresponding light-transmitting member. This allows the rear light assembly 200 to meet regulatory requirements and prevents light leakage, making it more aesthetically pleasing. Since the rear light assembly 200 includes all embodiments of the aforementioned rear light cover 100, it possesses at least all the beneficial effects of the aforementioned embodiments, which will not be elaborated further here.

[0041] According to another aspect of this utility model, a vehicle is also provided, including the rear light assembly 200 as described above, which is mounted at the rear of the vehicle. Since the vehicle encompasses all embodiments of the aforementioned rear light assembly 200, it possesses at least all the beneficial effects of all the aforementioned embodiments, which will not be elaborated upon here.

[0042] The above are merely exemplary embodiments of this utility model and do not limit the scope of protection of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
