Description

A smart-controlled car headlight Technical Field

[0001] This utility model belongs to the field of automotive parts, specifically, it relates to an intelligently controlled automotive headlight. Background Technology

[0002] The headlight assembly is the core component of a vehicle's front lighting system. It plays a crucial role in illuminating the road ahead at night and in low-visibility conditions, ensuring driving safety, and conveying the vehicle's position and driving intentions to other road users.

[0003] Existing traditional automotive front lighting systems suffer from three major technical bottlenecks: First, the switching between high and low beams relies on a mechanical baffle structure, resulting in slow response and susceptibility to wear; second, fog lights generally suffer from a central bright spot problem, with uniformity of only 70-80% and a rain / fog penetration distance of less than 32 meters; third, lamp positioning relies on ordinary planar contact, which is prone to displacement under vehicle vibration. Although existing technologies attempt to improve the beam pattern through complex lens assemblies, this leads to bulky size, high cost, and poor reliability. Summary of the Invention

[0004] In view of this, the technical problem to be solved by this utility model is to provide an intelligent controllable car headlight that solves the problems of slow response when switching between high and low beams, insufficient penetration of fog lights, and easy displacement.

[0005] To solve the above-mentioned technical problems, this utility model discloses an intelligent controllable automotive headlight, comprising: a lamp housing, a high / low beam integrated lamp chamber inside the lamp housing, an electrodeformable light guide layer at the bottom of the high / low beam integrated lamp chamber, a fog light chamber on the right side of the high / low beam integrated lamp chamber, an outwardly protruding mounting groove inside the fog light chamber, uniformly spaced light-diffusing strips around the outside of the mounting groove, a C-shaped reflector around the fog light chamber, an L-shaped positioning plate on the outer side of the bottom of the lamp housing, and a grid-shaped positioning strip on the outer surface of the positioning plate.

[0006] According to one embodiment of the present invention, the electrodeformable light guide layer is made of silicon-based flexible material, which deforms through current signal to change the angle of light refraction.

[0007] According to one embodiment of the present invention, the number of the above-mentioned light-diffusing strips is 10 sets.

[0008] The positioning plate is fixed to the lamp housing with bolts, and a fixed bracket is provided on the outside of the lamp housing.

[0009] According to one embodiment of the present invention, the above-mentioned integrated high and low beam headlights are provided with LED high beam headlights and LED low beam headlights in the headlight compartment, and the fog light headlights are provided with LED fog lights in the fog light compartment.

[0010] Compared with the prior art, the present invention can achieve the following technical effects:

[0011] The fog light achieves millisecond-level light pattern switching through an electrodeformable light guide layer, and innovatively adopts a composite structure of uniform light strips and reflectors to improve fog light performance, making it more penetrating. It is also combined with a grid-based positioning system to solve the problem of installation accuracy. Real-world tests show that, while maintaining the ECE R112 standard, this solution increases the effective illumination distance from 60m low beam / 180m high beam to 65m / 200m, and the fog light's rain and fog penetration distance reaches 45m (SAE J583 test), significantly improving overall performance.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the above technical effects at the same time. Attached Figure Description

[0017] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0018] Please refer to Figure 1, which is a schematic diagram of an intelligently controlled automotive headlight according to an embodiment of the present invention. As shown in the figure, an intelligently controlled automotive headlight includes: a lamp housing 10, a high / low beam integrated lamp chamber 20 inside the lamp housing 10, and a fog light chamber 40 on the right side of the high / low beam integrated lamp chamber.

[0019] In one embodiment of this utility model, a high beam and a low beam integrated lamp chamber 20 and a fog light chamber 40 are provided inside the lamp housing 10. An LED high beam and an LED low beam are installed in the high beam integrated lamp chamber 20, and a fog light is installed in the LED fog light chamber 40. The LED high beam can improve visibility and expand the field of view. The LED low beam plays a role in situations where close-range lighting is required, such as at night or in underground parking garages. The LED fog light can make the vehicle visible to other vehicles in foggy or rainy weather when visibility is greatly affected by the weather.

[0020] Furthermore, an electrodeformable light guide layer 30 is provided at the bottom of the integrated high and low beam light chamber 20.

[0021] In detail, the bottom of the integrated high and low beam lamp chamber 20 is provided with an electrodeformable light guide layer 30, which is made of silicon-based flexible material. The electrodeformable light guide layer 30 achieves dynamic deformation through current signal, quickly adjusts the light refraction angle, and realizes seamless switching between high and low beams, making the high and low beam switching speed 20 times faster than traditional mechanical baffles.

[0022] In addition, the fog light housing 40 is provided with an outwardly protruding mounting groove 41, and the mounting groove 41 is provided with evenly spaced light-diffusing strips 50 around its perimeter. The fog light housing 40 is provided with a C-shaped reflector 60 around its perimeter.

[0023] In detail, an outwardly protruding mounting groove 41 is provided inside the fog light chamber 40, and an LED fog light is installed inside the mounting groove 41. Uniformly spaced light-diffusing strips 50 are provided around the outside of the mounting groove 41, with 10 sets of light-diffusing strips 50. A C-shaped reflector 60 is provided outside the mounting groove 41. The design of the reflector 60 enhances its overall performance, and the light-diffusing strips 50 and reflector 60 form a composite optical structure, making the fog light spot more than 90% uniform and increasing the penetration distance to 45m.

[0024] Preferably, the bottom outer side of the lamp housing 10 is provided with an L-shaped positioning plate 70, and the outer surface of the positioning plate 70 is provided with a grid-shaped positioning strip 80.

[0025] In detail, a grid-type positioning strip 80 is set on the outside of the L-shaped positioning plate 70. The positioning plate 70 is fixed to the lamp housing 10 by titanium alloy bolts. The positioning plate 70 and the lamp housing 10 achieve a flatness of ≤0.05mm by cooperating with the titanium alloy bolts, which greatly improves the installation accuracy, doubles the vibration resistance, and greatly extends the service life.

[0026] Secondly, a fixing bracket is provided on the outside of the lamp housing 10. Each fixing bracket has two sets of mounting holes. The car frame and the fixing bracket are connected by bolts through the mounting holes, which is highly practical. The positioning bracket improves the positioning accuracy of the car lamp and tightly connects the lamp to the car frame, making it less prone to shaking. A lamp cover with a snap-fit ​​connection is provided on the outside of the lamp housing 10 to seal the lamp housing 10 and prevent moisture from entering and damaging the high / low beam lamp housing and fog light housing. A sealing gasket is provided at the bottom of the lamp cover around the perimeter to seal the lamp housing and the lamp cover, further enhancing its sealing performance.

[0027] In summary, this invention achieves millisecond-level light pattern switching through an electrodeformable light guide layer 30, innovatively employs a composite structure of a uniform light strip 50 and a reflector 60 to enhance fog light performance, resulting in stronger penetration, and utilizes a grid-based positioning system to solve installation accuracy issues. Actual measurements show that, while maintaining the ECE R112 standard, this solution increases the effective illumination distance from 60m low beam / 180m high beam to 65m / 200m, and the fog light's rain and fog penetration distance reaches 45m (SAE J583 test), significantly improving overall performance.
