Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a projection headlight capable of achieving both high and low beams. Background Technology

[0002] Currently, most car headlights are LED headlights, which mainly consist of LED beads, a light source circuit board, and lenses corresponding to the LED beads. A group of LED beads is set on the light source circuit board, and high and low beam components are set on the corresponding LED beads to realize the high beam and low beam functions of the headlights. With the development of automotive technology, many cars are equipped with projection lights to project interactive patterns onto the ground.

[0003] Existing automotive headlights and projection lights are mostly separate components, requiring significant space and resulting in relatively high costs. For example, patent CN212746309U discloses an automotive light optical component and a headlight incorporating it, which includes a light source module, a lens, and a condenser. The condenser is positioned between the light source module and the lens, with the lens located at the front of the headlight. Another example is patent CN217640023U, which discloses an intelligent interactive testing system for a vehicle DLP projection light, comprising a vehicle front-view camera, a vehicle DLP controller, a vehicle DLP projection light, and an external display device. In these cases, the high and low beam headlights and the automotive projection light are separate components, requiring two separate installation spaces and resulting in relatively high costs. Utility Model Content

[0004] In view of the shortcomings of existing technology, this utility model provides a projection vehicle light that can realize both high and low beams, so as to achieve integrated installation and relatively low cost.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The projection vehicle headlight capable of achieving high and low beams includes a headlight housing, a high and low beam structure for achieving high and low beam functions, and a projection structure for achieving a projected pattern. It also includes a heat sink, wherein the high and low beam structure and the projection structure are disposed on the same heat sink and are both located in the headlight housing.

[0006] Further or preferred: The high and low beam structures and the projection structure are both located on one side of the heat sink, while a cooling fan is located on the other side of the heat sink.

[0007] A lens bracket is provided on one side of the heat sink, and the high beam, low beam and projection structure are all connected to the lens bracket.

[0008] The heat sink is an integral heat dissipation structure; there are two cooling fans, one corresponding to the high and low beam structure and the other corresponding to the projection structure.

[0009] The lens holder is provided with a decorative frame, and the projection structure includes a projection component and a projection lens disposed on the projection component. The decorative frame is provided with a projection lens positioning hole corresponding to the projection lens.

[0010] The lens holder is provided with a lens, and the decorative frame is provided with a lens positioning hole that matches the protrusion of the lens.

[0011] The near and far beam structures and the projection structure are arranged side by side, and the light source circuit boards of both the near and far beam structures and the projection structure are located on the heat sink.

[0012] The headlight source circuit board for the high and low beam structure and the projection source circuit board for the projection structure are two independent circuit boards, which are arranged side by side.

[0013] The headlight circuit board for the high and low beam structure and the projection light source circuit board for the projection structure are integrated into a single circuit board.

[0014] Compared with the prior art, this utility model has the following advantages: The projection headlight structure, which can realize both high and low beams, is reasonably designed. It integrates the high and low beam components and the projection component into one headlight. The light source circuit board and heat dissipation structure of both are integrated, resulting in a compact structure that does not require separate installation and has a relatively low cost.

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0021] like Figures 1 to 4 As shown, the projection headlight capable of achieving both high and low beams includes a headlight housing, a heat sink 1, a high and low beam structure for achieving high and low beam functions, and a projection structure for achieving a projected pattern; the high and low beam structure and the projection structure are mounted on the same heat sink and are both located in the same headlight housing, forming a headlight structure that integrates high and low beam functions and projection functions.

[0022] Both the high and low beam structure 5 and the projection structure are located on one side of the heat sink 1, and the cooling fan 3 is located on the other side of the heat sink. The cooling fan is integrated into the heat sink, resulting in a compact structure.

[0023] Furthermore, the heat sink is a single integrated heat dissipation structure; there are two cooling fans, one for the high and low beam structure and the other for the projection structure, which provides efficient heat dissipation and a simple structure.

[0024] A lens bracket 2 is provided on one side of the heat sink, and the high and low beam structures and the projection structure are all connected to the lens bracket. For example... Figure 4 As shown, the projection structure is connected to the lens bracket through the positioning plate 601, and the structure is stable and reliable.

[0025] The lens holder has a decorative frame 7. The projection structure includes a projection component 6 and a projection lens 603 mounted on the projection component. A separate heat dissipation structure 602 is provided on one side of the projection component. The decorative frame has a projection lens positioning hole 702 corresponding to the projection lens. The lens holder has a lens 8, and the decorative frame has a lens positioning hole 701 that mates with the protrusion of the lens. Its structure is compact, and the interlocking structure improves structural stability.

[0026] The high and low beam structures and the projection structure are arranged side by side. The light source circuit boards 4 of both the high and low beam structures and the projection structure are located on the heat sink. The heat sink is an integral heat dissipation structure. The mounting surface of the heat sink is a plane with a slot. The light source circuit board is equipped with a clip that matches the slot. The positioning is accurate and reliable, and the installation of the light source circuit board is simple.

[0027] like Figure 2 As shown, the headlight light source circuit board of the high and low beam structure and the projection light source circuit board of the projection structure are integrated into a single circuit board. The high and low beam components are equipped with lighting sources on the single circuit board, and the projection components are equipped with lens light sources on the single circuit board. The integrated design is compact and can effectively reduce costs.

[0028] Or such as Figure 4 As shown, the headlight light source circuit board 401 with high and low beam structure and the projection light source circuit board 402 with projection structure are two independent circuit boards, which are arranged side by side; the headlight light source circuit board is equipped with an illumination source, and the projection light source circuit board is equipped with a projection source.

[0029] This utility model enables a vehicle headlight with a reasonable design that integrates both high and low beam projection components and a projection component into a single headlight. The light source circuit boards and heat dissipation structures of both components are integrated, resulting in a compact structure that eliminates the need for separate components and has a relatively low cost.
