Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a baffle structure and an automotive headlight. Background Technology

[0002] Currently, flattening and conformal design are among the main development trends in automotive headlight styling. Typically, the imaging system in a headlight optical system consists of a reflector and a lens. For lens modules, when traditional lenses are used in flat or conformal designs, the lens portion in the light-emitting direction is very thick, which is not conducive to processing and shaping, nor to optical effects, resulting in severe chromatic dispersion and low light transmittance, leading to low luminous efficiency.

[0003] In addition, for the entire optical system, in order to meet the requirements of the near light cutoff line, baffles are set in front and behind the light in the light ingress and light egress directions to obtain a light pattern with a cutoff line; however, the existing optical system, especially the optical system in new energy vehicles, has relatively limited installation space.

[0004] like Figure 1 and Figure 2 As shown, existing solutions typically extend the front end of the baffle forward to form a concave arc surface structure. However, this can affect light distribution and space utilization in certain situations. Since LEDs are not point light sources, the focusing system cannot perfectly collimate the light. If the baffle is made into a thick-walled system, some light will undergo total internal reflection on the front surface of the thick-walled component due to the unevenness of the edge area. This prevents the utilization of large-angle light rays, resulting in a narrower left and right range of the light pattern, low efficiency, and poor performance. Summary of the Invention

[0008] Furthermore, the top surface of the baffle has a first protrusion and a second protrusion in the middle, and the first protrusion and the second protrusion are connected to the top surface of the baffle by a curved surface.

[0009] Furthermore, the height of the first protrusion is less than the height of the second protrusion.

[0010] Furthermore, the baffle body has a mounting surface extending downward from the rear side of the baffle member, and the concentrator and connecting block are integrated on the mounting surface.

[0011] Furthermore, several raised strips are evenly distributed on the top surface of the baffle.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] like Figure 3 and Figure 4 As shown, a baffle structure includes a baffle body 100, which is an integral structure. It includes a baffle component 1, a concentrator 2, and a connecting block 3. The front end of the baffle component 1 is flat. The concentrator 2 and the connecting block 3 are integrated on the rear side of the baffle component 1. The two ends of the baffle component 1 are raised and transition to the top surface of the baffle component 1 through a curved surface. The top surface of the baffle component 1 also has two protrusions in the middle to meet design standards.

[0026] The baffle member 1 has two ends that are raised to the same height. The top surface of the baffle member 1 has a first protrusion 11 and a second protrusion 12 in the middle, which transition to the top surface of the baffle member 1 via a curved surface. The height of the first protrusion 11 is less than the height of the second protrusion 12. Several raised strips 13 are evenly distributed on the top surface of the baffle member 1 to form a near-beam cutoff line.

[0027] like Figure 5 As shown, the cutoff outline of the baffle 1 curves upward at both ends, which reduces the installation space at the front and rear, making it suitable for different working conditions and scenarios, especially for new energy vehicles, to meet the requirements of flat and conformal automotive headlights.

[0028] The baffle 1 in this embodiment can also be used in a thick-walled component system. For example, it can be the upper / lower surface of a thick-walled component with both ends curving upwards. The front surface of the thick-walled component is relatively flat, so light will be emitted along its surface, greatly improving efficiency.

[0029] Preferably, the baffle body 100 has a mounting surface 4 extending downward from the rear side of the baffle member 1, and the concentrator 2 and the connecting block 3 are integrated on the mounting surface 4.

[0030] Preferably, the surface of the baffle 1 is coated with an aluminum layer or covered with an anti-reflective film. In this way, the reflectivity of the baffle 1 is >70%, increasing the efficiency of the optical system.

[0031] As needed, the surface of the baffle 1 is provided with light-distributing patterns and textures.

[0032] The baffle body 100 is positioned between the primary optical system and the imaging system. In practical applications, the number of baffle bodies 100 and the number of units in the primary optical system are not limited and can be adjusted and changed according to actual needs. The angle and curvature of the two ends of the baffle 1 can also be adjusted according to actual needs. The assembly method between the baffle body 100 and each component is designed according to actual requirements.

[0033] Since the baffle structure in this example reduces the installation space at the front and rear, an automotive headlight including the baffle structure of this embodiment can be designed.

[0034] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
