Description

Technical Field

[0001] This utility model relates to the field of motor vehicle auxiliary driving lights, and in particular to an optical structure for a motor vehicle strip auxiliary driving light with high beams, low beams and background daytime running lights. Background Technology

[0002] Currently, in automotive driver assistance lights with reflector-based optical structures, the reflector is an opaque electroplated component, limiting the placement of only one main LED at the focal point. To add daytime running light functionality, a diffuser or light guide plate is typically added around the reflector. This design necessitates a larger light body, especially for strip-shaped driver assistance lights. Increased size affects installation and generates greater wind resistance and noise during vehicle operation.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Currently, for vehicle auxiliary driving lights, especially those with a strip-shaped reflector optical structure, adding daytime running light functionality requires a separate diffuser or light guide plate design, which necessitates increasing the size of the lamp body and raising costs. Utility Model Content

[0004] To improve current vehicle auxiliary driving lights, especially those with a strip-shaped reflector optical structure, adding daytime running light functionality requires a separate diffuser or light guide plate. Such a design would increase the size of the lamp body and raise costs. This application provides a strip-shaped auxiliary driving light optical structure for motor vehicles with high and low beams and background daytime running lights.

[0005] This application provides a motor vehicle strip-shaped auxiliary driving light optical structure with high and low beams and background daytime running lights, adopting the following technical solution: A motor vehicle strip-shaped auxiliary driving light optical structure with high and low beams and background daytime running lights includes a lamp body, a light source driver board, light source driver board fixing screws, a reflector, a lens sealing strip, a transparent lens, a lens clamping steel strip, a sealing gasket, an end cap, and an end cap fixing screw. The bottom of the inner cavity of the lamp body is provided with a light source driver board fixing screw hole and an angled fastener. The open end of the lamp body is provided with a sealing strip groove. The bottom of the inner cavity of the lamp body is provided with a light source driver board, and the light source driver board is fixed to the bottom of the inner cavity of the lamp body by the light source driver board fixing screw. The reflector includes a focusing reflector and a flood reflector, and the bottom of the focusing reflector and the flood reflector... Each lamp body is equipped with two positioning posts. The side surfaces of the focusing reflector and the floodlight reflector are provided with reflector fixing buckles. The back of the reflector is plated with an electroplated surface. The open end of the lamp body is provided with a sealing strip groove, a lens slot, and a steel strip slot. The inside of the sealing strip groove is provided with a lens sealing strip. The inside of the lamp body is provided with a transparent lens, and the surface of the transparent lens is provided with a lens pressing steel strip. The light source driving board includes a driving board. The surface of the driving board is provided with a main light LED and a daytime running light LED. The main light LED is located at the focal position at the bottom of the reflector. The daytime running light LED is located between the focusing reflector and the floodlight reflector. The light from the daytime running light LED is reflected by the electroplated surface on the back of the reflector and then emitted through the gap between the reflectors. The surface of the driving board is provided with positioning holes.

[0006] Further, the lamp body is provided with end caps at both ends, and a sealing gasket is provided at the connection between the end caps and the lamp body. The end caps are fixed to the left and right ends of the lamp body by end cap fixing screws. The left and right ends of the lamp body are provided with end cap screw holes. The inside of the focusing reflector cup is provided with a focusing cup main lamp reflector surface, and the inside of the floodlight reflector cup is provided with a floodlight main lamp reflector surface.

[0007] Furthermore, the focusing reflector and floodlight reflector of the reflector cup form a mixed high beam and low beam light pattern by reflecting the LED light from the main light.

[0008] Furthermore, the positioning post and the positioning hole are connected by an insertion connection, and the surface of the reflector cup fixing buckle contacts the inner wall of the angled buckle position.

[0009] Further configuration includes two sets of positioning posts, one set of reflector cup fixing buckles, and the surface of the lens pressing steel strip in contact with the inner wall of the lamp body.

[0010] Furthermore, the light emitted by the daytime running light LED is diffusely reflected by the electroplated surface on the back of the reflector to form a soft background light.

[0011] In a further configuration, after the lens pressing steel bar is inserted into the steel bar slot, it presses down on the transparent lens and the lens sealing strip to achieve a double seal.

[0012] Compared with related technologies, the optical structure of the motor vehicle strip-shaped auxiliary driving light with high and low beams and background daytime running lights provided by this utility model has the following beneficial effects: This utility model provides an optical structure for a motor vehicle strip-shaped auxiliary driving light with high and low beams and a background daytime running light. Through precise alignment of the main LED on the surface of the light source driver board with the focal point at the bottom of the reflector cup, combined with the differentiated curved surface design of the main LED reflector surface of the focusing reflector cup and the main LED reflector surface of the floodlight reflector cup, a superposition of highly focused high beam and broadly diffused low beam light patterns is achieved. Two sets of positioning posts at the bottom of the reflector cup are inserted into the positioning holes of the light source driver board, and a snap-fit ​​connection is made between the reflector cup fixing buckle and the inclined buckle position inside the lamp cavity, doubly constraining the axial displacement of the reflector cup and ensuring the stability of the optical system. The gap between the reflectors serves as the light transmission path for the daytime running light LED, and its width limits the light divergence angle. Combined with the high-reflectivity electroplated surface on the back of the reflector cup guiding the diffuse reflection of the daytime running light light, a uniform and soft ring-shaped background light effect is formed. This achieves an integrated design of main light illumination and daytime running light warning functions, reducing the number of parts, simplifying the manufacturing process and structure, and lowering costs.

[0013] This utility model provides an optical structure for a motor vehicle strip-shaped auxiliary driving light with high and low beams and a background daytime running light. After a transparent lens is embedded in a lens slot, a lens-pressing steel strip is inserted into the steel strip slot, forcing the lens sealing strip to elastically deform, forming the first dynamic sealing barrier. The surface of the lens-pressing steel strip is tightly attached to the inner wall of the lamp body, forming the second sealing line, preventing water vapor and dust from entering along the lens edge. Both ends of the lamp body are sealed by end caps, and a sealing gasket is set at the joint between the end cap and the lamp body and is pressed by the end cap fixing screws to prevent liquid longitudinal penetration. The tool-less insertion and matching of the positioning post and the positioning hole, combined with the snap-fit ​​connection of the reflector cup fixing buckle and the angled buckle, realizes the quick replacement of the reflector cup module and ensures the consistency of the light source position, avoiding optical axis misalignment. The gap of the reflector cup is used as the light source carrier for the daytime running light, integrating the functions of the main light and the daytime running light in a limited space, improving the integration of the lamp.

[0016] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model. Example 1:

[0017] like Figure 1-8As shown, the present invention discloses a motor vehicle strip-shaped auxiliary driving light optical structure with high and low beams and background daytime running lights, comprising a lamp body 1, a light source driver board 2, a light source driver board fixing screw 3, a reflector 4, a lens sealing strip 5, a transparent lens 6, a lens clamping steel strip 7, a sealing gasket 8, an end cap 9, and an end cap fixing screw 10. The bottom of the inner cavity of the lamp body 1 is provided with a light source driver board fixing screw hole 11 and a slanted fastening position 12. The open end of the lamp body 1 is provided with a sealing strip groove 13. The light source driver board 2 is located at the bottom of the inner cavity of the lamp body 1, and the light source driver board 2 is fixed to the bottom of the inner cavity of the lamp body 1 by the light source driver board fixing screw 3. The reflector 4 includes a focusing reflector 41 and a flood reflector 42, and both the focusing reflector 41 and the flood reflector 42 are provided with two positioning posts 401 at their bottoms. The side surfaces of reflector cup 42 are all provided with reflector cup fixing buckles 402. The back of reflector cup 4 is plated with an electroplated surface 403. The open end of lamp body 1 is provided with a sealing strip groove 13, a lens slot 14 and a steel strip slot 15. The inside of the sealing strip groove 13 is provided with a lens sealing strip 5. The inside of lamp body 1 is provided with a transparent lens 6. The surface of the transparent lens 6 is provided with a lens pressing steel strip 7. The light source drive board 2 includes a drive board 21. The surface of the drive board 21 is provided with a main light LED 22 and a daytime running light LED 23. The main light LED 22 is located at the bottom focal position of reflector cup 4. The daytime running light LED 23 is located between the spotlight reflector cup 41 and the floodlight reflector cup 42. The light from the daytime running light LED 23 is reflected by the electroplated surface 403 on the back of the reflector cup and then emitted through the reflector cup gap 404. The surface of the drive board 21 is provided with a positioning hole 24.

[0018] like Figure 1-8 As shown, end caps 9 are provided at both ends of the lamp body 1, and sealing gaskets 8 are provided at the connection between the end caps 9 and the lamp body 1. The end caps 9 are fixed to the left and right ends of the lamp body 1 by end cap fixing screws 10. End cap screw holes 16 are provided at both ends of the lamp body 1. The inside of the focusing reflector cup 41 is provided with a focusing cup main lamp reflector surface 411, and the inside of the floodlight reflector cup 42 is provided with a floodlight main lamp reflector surface 421.

[0019] like Figure 1-8 As shown, the focusing reflector 41 and the floodlight reflector 42 of the reflector cup 4 form a mixed high beam and low beam light pattern by reflecting the light from the main light LED22.

[0020] like Figure 1-8 As shown, the positioning post 401 is connected to the positioning hole 24 by a plug-in connection, and the surface of the reflector cup fixing buckle 402 is in contact with the inner wall of the angled buckle position 12.

[0021] like Figure 1-8 As shown, there are two sets of positioning posts 401 and one set of reflector cup fixing buckle 402. The surface of the lens pressing steel strip 7 is in contact with the inner wall of the lamp body 1.

[0022] like Figure 1-8 As shown, the light emitted by the daytime running light LED23 is diffusely reflected by the electroplated surface 403 on the back of the reflector to form a soft background light.

[0023] like Figure 1-8 As shown, after the lens pressing steel strip 7 is inserted into the steel strip slot 15, it presses down the transparent lens 6 and the lens sealing strip 5 to achieve a double seal.

[0024] The advantages of this technical solution in practical applications include, but are not limited to, the following: 1. The reflector cup 4 double curved surface design, combined with the positioning and buckle double fixing mechanism, achieves accurate superposition of high and low beams and stable light pattern. The daytime running light LED23 uses the gap of the reflector cup 4 and the electroplated surface 403 for diffuse reflection to form a controllable warning light effect. 2. The transparent lens 6 presses the lens pressing steel strip 7 and the lens sealing strip 5 to form a dynamic sealing system. The end cap 9 and the sealing gasket 8 form a longitudinal waterproof barrier. The reflector cup 4 adopts a tool-free quick-release design to ensure the consistency of the optical axis after disassembly and assembly.

[0025] In this technical solution, a light source driver board 2 is fixed to the bottom of the inner cavity of the lamp body 1 by a light source driver board fixing screw 3. The main lamp LED 22 on its surface is precisely aligned with the bottom focal position of the reflector cup 4. The reflector cup 4 consists of a focusing reflector cup 41 and a flood reflector cup 42. Both have two sets of positioning posts 401 at their bottom, which are inserted and cooperate with the positioning holes 24 of the driver board 21 to achieve quick positioning and stable fixation. The reflector cup fixing buckle 402 is inserted into the inclined buckle position 12 in the inner cavity of the lamp body 1 to further limit the axial displacement of the reflector cup 4 and ensure the stability of the optical system. The light emitted by the main lamp LED 22 is efficiently focused by the focusing cup main lamp reflector surface 411 of the focusing reflector cup 41 to form a high-brightness high beam. At the same time, the flood reflector cup... The main lamp reflector 421 of the floodlight cup 42 diffuses the light, forming a broad low beam. The two reflectors 4 are arranged in an arc shape, and the difference in curvature of their side surfaces is used to achieve the superposition of the high beam and low beam. Finally, the mixed light pattern that meets the regulatory requirements is output through the transparent lens 6. The daytime running light LED23 is placed in the gap area between the focusing reflector 41 and the floodlight reflector 42. Its direct light cannot be emitted directly due to the solid blockage of the reflector 4. The back of the reflector 4 is coated with a high reflectivity electroplated surface 403. This electroplated surface 403 reflects the direct light of the daytime running light LED23 towards the inner cavity of the lamp body 1, forming a diffuse reflection effect. The light diffused by the electroplated surface 403 is scattered multiple times in the inner cavity of the lamp body 1 before passing through the reflector. The reflector cup gap 404 between the two reflectors allows light to shine outward, forming a uniform and soft ring-shaped background light effect. The light transmission path is strictly limited by the width of the reflector cup gap 404 to avoid excessive light divergence angle, ensuring that the daytime running light LED23 is used only as a warning light source and does not affect the lighting function of the main light LED22. The transparent lens 6 is embedded in the lens slot 14 at the opening end of the lamp body 1, and its edge is pressed by the lens pressing steel strip 7. After the lens pressing steel strip 7 is inserted into the steel strip slot 15, it forces the lens sealing strip 5 to undergo elastic deformation, filling the gap between the transparent lens 6 and the lamp body 1, forming the first sealing barrier. The surface of the lens pressing steel strip 7 is tightly attached to the inner wall of the lamp body 1, preventing external moisture and dust from spreading along the edge of the transparent lens 6. To prevent liquid from penetrating longitudinally along the lamp body 1, a second line of defense is formed by sealing the left and right ends of the lamp body 1 with end caps 9. A sealing gasket 8 is provided at the joint between the end cap 9 and the lamp body 1, and it is pressed by the end cap fixing screws 10. The insertion and engagement of the positioning post 401 and the positioning hole 24 can complete the initial positioning without tools. With the snap-fit ​​connection between the reflector cup fixing buckle 402 and the angled buckle 12, the reflector cup 4 can be quickly replaced. The correspondence between the positioning hole 24 and the positioning post 401 ensures the consistency of the light source position after each disassembly and assembly, avoiding optical axis deviation. The gap of the reflector cup 4 is used as the carrier of the daytime running light source, integrating the functions of the main light LED 22 and the daytime running light LED 23 in a limited space, improving the integration of the lamp.
