Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and more specifically, relates to an automotive lighting structure. Background Technology

[0002] Along with vehicle styling trends, headlights are also becoming longer (e.g., increasing to approximately 1 meter in length). Consequently, the thermal expansion of the exterior lenses caused by sunlight is becoming increasingly significant, leading to a rise in complaints of cracked exterior lenses in the summer. Current solutions involve adjustable mounting bolts and headlight bodies, but this negatively impacts assembly and matching accuracy. Furthermore, sunlight causes the internal temperature of the headlight to rise, causing moisture to evaporate from the resin components. This evaporated moisture condenses on the inner surface of the exterior lens, affecting both headlight performance and appearance.

[0003] Existing technology includes a specification titled "Thick-walled Light Guide Component, Vehicle Light," with publication number CN114857536B. This technology discloses a thick-walled light guide component comprising: a body, one side of which is formed as a first reflective surface, and the other side as a light-emitting surface; multiple reflective units are disposed on the body, each including an upper reflective groove and a lower reflective groove, the upper reflective groove being formed on the upper surface of the body, and the lower reflective groove being formed on the lower surface of the body; and two concentrators. A portion of the light passing through one concentrator is reflected by the first reflective surface and exits from the light-emitting surface, while another portion of the light passing through the same concentrator is reflected sequentially by the first reflective surface, the upper reflective groove, and the lower reflective groove before exiting from the light-emitting surface. Similarly, a portion of the light passing through the other concentrator is reflected by the first reflective surface and exits from the light-emitting surface, while another portion of the light passing through the other concentrator is reflected sequentially by the first reflective surface, the lower reflective groove, and the upper reflective groove before exiting from the light-emitting surface. This invention has the advantages of guiding light of different colors while possessing a compact structure and good lighting effect. However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automotive lamp structure that is simple in structure, alleviates the problem of internal temperature rise of external lens and moisture evaporation of internal components of lamp body, and reliably realizes the precise positioning of lamp body when the lamp is installed with the vehicle body, in order to overcome the shortcomings of the existing technology.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model relates to an automotive lighting structure, comprising an external lens and a lamp body. The external lens is fixedly connected to the front of the lamp body. An infrared reflective film layer is provided on the outer surface of the external lens. The external lens has an outwardly convex arc structure in the horizontal direction and an outwardly convex arc structure in the vertical direction. A light source substrate is provided inside the lamp body.

[0007] A decorative frame is provided inside the lamp body, and a thick-walled component is provided on the decorative frame.

[0008] The light source substrate includes a first light source substrate and a second light source substrate, with the first light source substrate located at the upper position and the second light source substrate located at the lower position.

[0009] The thick-walled component includes a first thick-walled component and a second thick-walled component, with the first thick-walled component located at the upper position and the second thick-walled component located at the lower position.

[0010] The lamp body is installed at the vehicle body mounting position and is connected to the vehicle body panel.

[0011] The bolt passes through the body panel, and a nut is screwed onto one end of the bolt. The lamp body is located on one side of the body panel, and the nut is located on the other side of the body panel.

[0012] The bolt has a groove at its end and an extension at the rear of the lamp body, the extension including a body and a bent edge.

[0013] The main body and the bent edge of the extension are configured in an L-shape.

[0014] When the rear part of the lamp body and the body panel are connected by bolts and nuts, the bent edge of the extension is configured to be able to be fitted into the groove of the bolt end.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] The automotive lighting structure described in this utility model features an external lens fixedly connected to the front of the lamp body, which is then connected to the vehicle body panel, ensuring reliable lamp installation. An infrared reflective film is applied to the outer surface of the external lens. Visible light can pass through the lens, while infrared light is reliably reflected and blocked by the film, preventing sunlight from causing internal temperature rise and moisture evaporation from the resin components. This avoids condensation on the inner surface of the external lens, ensuring both lamp performance and appearance. The external lens has a convex arc structure in both the horizontal and vertical directions, resulting in divergent light emission and increased light coverage. Bolts and nuts connect the lamp body and the vehicle body panel, ensuring a reliable lamp body connection. The bent edge of the extension engages with the groove at the bolt end, reliably positioning the lamp body relative to the bolt and ensuring a secure connection between the lamp body and the bolt, thus guaranteeing the installation accuracy of the lamp body connected to the vehicle body panel.

Detailed Implementation

[0022] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0023] As attached Figure 1 -Appendix Figure 3 As shown, this utility model is a structure for an automotive lamp, including an outer lens 1 and a lamp body 2. The outer lens 1 is fixedly connected to the front of the lamp body 2. An infrared reflective film layer 16 is provided on the outer surface of the outer lens 1. The outer lens 1 has an outwardly convex arc structure in both the horizontal and vertical directions. A light source substrate is provided inside the lamp body 2. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In this configuration, the outer lens 1 is fixedly connected to the front of the lamp body 2, and the lamp body is connected to the vehicle body panel, ensuring reliable installation of the lamp. The infrared reflective film layer 16 on the outer surface of the outer lens 1 allows visible light to pass through while infrared light is reliably reflected and blocked by the infrared reflective film. This prevents sunlight from causing the internal temperature of the lamp to rise, leading to evaporation of moisture from the resin components inside the lamp, and condensation on the inner surface of the outer lens, thus ensuring the performance and appearance of the vehicle lamp. The external lens 1 has a convex arc-shaped structure in both the horizontal and vertical directions. The light emitted from the external lens is divergent, increasing the light coverage area. The automotive lamp structure described in this utility model is simple in structure, alleviates the problem of temperature rise inside the external lens and moisture evaporation in the lamp body components, and reliably achieves precise positioning of the lamp body during installation on the vehicle body.

[0024] A decorative frame 5 is provided inside the lamp body 2, and a thick-walled component is provided on the decorative frame 5. In the above structure, the thick-walled component is installed inside the lamp body and is fixedly connected to the lamp body to ensure a reliable connection.

[0025] The light source substrate includes a first light source substrate 9 and a second light source substrate 10, with the first light source substrate 9 located at the upper position and the second light source substrate 10 located at the lower position. In this structure, the first light source substrate 9 and the second light source substrate 10 are fixed to the lamp body, and the connection is reliable.

[0026] The thick-walled components include a first thick-walled component 6 and a second thick-walled component 7, with the first thick-walled component 6 located at the upper position and the second thick-walled component 7 located at the lower position. The lamp body 2 is installed at the vehicle body mounting position and is connected to the vehicle body panel 11. A bolt 3 passes through the vehicle body panel 11, and a nut 4 is screwed onto one end of the bolt 3 that passes through the vehicle body panel 11. The lamp body is located on one side of the vehicle body panel, and the nut is located on the other side of the vehicle body panel. The bolt end 12 of the bolt 3 has a groove portion 13, and the rear of the lamp body 2 has an extension portion, which includes a body portion 14 and a bent edge 15. In the above structure, the lamp body needs to be connected to the vehicle body panel, and the bolt and nut cooperate to achieve the connection between the lamp body and the vehicle body panel. The bolt structure is specially designed so that the bolt simultaneously fixes and connects the lamp body, ensuring that the lamp body and the bolt are an integral structure, thereby ensuring the installation accuracy after the lamp body is installed in place.

[0027] The main body 14 and the bent edge 15 of the extension are configured in an L-shape. When the lamp body 2 and the body panel 11 are connected by bolts 3 and nuts 4, the bent edge 15 of the extension is configured to be able to be fitted into the groove 13 of the bolt end 12. After the bolt 3 passes through the body panel 11, the nut is tightened, and the lamp body 2 and the body panel 11 are fixedly connected.

[0028] The automotive lighting structure of this utility model features an external lens 1 fixedly connected to the front of the lamp body 2, which is then connected to the vehicle body panel for reliable installation. An infrared reflective film layer 16 is provided on the outer surface of the external lens 1. This allows visible light to pass through the lens while infrared light is reliably reflected and blocked by the film, preventing the lamp's internal temperature from rising due to sunlight and the evaporation of moisture from the resin components. This avoids condensation on the inner surface of the external lens, ensuring both the lamp's performance and appearance. The external lens 1 has a convex arc-shaped structure in both the horizontal and vertical directions, resulting in divergent light emission and increased light coverage. The bolts and nuts connect the lamp body and the body panel, ensuring a reliable connection of the lamp body. The bent edge 15 of the extension is designed to fit into the groove 13 of the bolt end 12, thus reliably positioning the relative position of the lamp body and the bolt, ensuring a reliable connection between the lamp body and the bolt, and guaranteeing the installation accuracy of the lamp when connecting the lamp body and the body panel.
