[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0028] Reference Figures 1-8The utility model provides a kind of double light lens car light, including front and rear arrangement for constituting the car light outer frame car light front shell 1 and car light rear shell 2, it can be used to protect internal optical and electronic components, while providing installation and fixed basis, wherein, car light front shell 1 front end can install lens 3, car light rear shell 2 inside can accommodate radiator 6 and high-low light source module and other components.Lens 3 is located at the front end of car light front shell 1, can be used to focus and diffuse light, when light emitted by light source passes through lens, lens will adjust the propagation direction of light, so that it forms high beam and low beam light type in line with design requirements.The fixed support 4 connected between car light front shell 1 and car light rear shell 2 can be used to support high beam switching mechanism 5 and other internal components of car light, to ensure that the position of optical element is accurate and stable.High beam switching mechanism 5 is located behind lens 3, when user needs high beam light type, high beam switching mechanism 5 can adjust light path, so that high beam light passes through lens 3 and shoots out, and when user needs low beam light type, high beam switching mechanism 5 can change light path, so that low beam light passes through lens 3 and shoots out.Radiator 6 is provided in car light rear shell 2, wherein, radiator 6 can conduct and dissipate heat generated by light source substrate to air through its metal material and heat dissipation fin, to reduce the temperature of light source substrate, prolong the service life of car light, while improving the stability and reliability of light source.The lower end of radiator 6 is provided with heat dissipation fan 7 for accelerating air flow, to enhance the heat dissipation effect of radiator 6, and ensure that light source substrate can still operate at low temperature for a long time.The front end of radiator 6 is recessed downward with step 61, which can optimize the layout of internal space of car light, not only can fix high beam light source substrate 8 and prism 9, but also can ensure the accuracy and stability of high beam light path.Prism 9 located above high beam light source substrate 8 can accurately control the direction and distribution of high beam light, adjust high beam light path, cooperate with high beam switching mechanism 5 arranged in front of it, to form high beam light type in line with design requirements, to improve the illumination effect and switching efficiency of high beam.Further, high beam light shield plate 91 is arranged on prism 9 for shielding unnecessary scattered light, to avoid glare of high beam light, improve driving safety.The upper end of radiator 6 is fixed with low beam light source substrate 10, and low beam light reflector cup 101 is arranged on low beam light source substrate 10 for reflecting and focusing light emitted by low beam light source substrate 10, to form uniform distribution of low beam light type, to avoid local over-brightness or over-darkness, improve the illumination effect and driving comfort of low beam.It is obvious that, in the utility model, the application can realize efficient heat dissipation, accurate light path control, fast high beam switching and uniform illumination through the collaborative design of various structures, while it can also significantly improve the performance, reliability and service life of car light, to meet the high standard requirements of modern cars for car light.

[0029] In detail, in the embodiment, the high beam light source substrate 8 and the low beam light source substrate 9 can emit light after being powered on. When the low beam mode of the double light lens vehicle lamp is used, the low beam light emitted by the low beam light source substrate 9 can enter the lens 3 directly after being reflected and focused by the low beam reflecting cup 101, so as to form a uniformly distributed low beam light type. At the same time, the high beam light emitted by the high beam light source substrate 8 can enter the high beam switching mechanism 5 after being adjusted by the prism 9. At this time, the high beam switching mechanism 5 is in a closed state without the user controlling the action of the high beam switching mechanism 5, and part of the high beam light can directly enter the lens 3 through the prism 9, thereby enhancing the illumination brightness of the low beam. When the high beam mode of the double light lens vehicle lamp is used, the high beam light source substrate 8 can emit high beam light after being powered on. The high beam light can enter the high beam switching mechanism 5 after being adjusted by the prism 9. At this time, the user can control the high beam switching mechanism 5 to open the high beam light path to allow the high beam light to pass through and directly enter the lens 3 to form a high beam light type. At the same time, the high beam light shield 91 arranged above the prism 9 can block unnecessary scattered light to avoid glare.

[0030] In addition, in the utility model, the high beam and the low beam can be efficiently switched, the brightness of the low beam mode is enhanced through auxiliary lighting, and the overall performance and practicality of the vehicle lamp are improved.

[0031] Further, in the embodiment, as shown in Figure 6 Figure 7 The lower end of the prism 9 is provided with a reflecting cup 95 protruding downward. The light inlet of the reflecting cup 95 is arranged correspondingly to the high beam lamp bead on the high beam light source substrate 8, so as to ensure that the light emitted by the high beam lamp bead can directly enter the reflecting cup 95. After the light emitted by the high beam lamp bead enters the reflecting cup 95, the light can be reflected and focused by the inner wall of the reflecting cup, so that the high beam light is concentrated and adjusted in direction to enter the prism 9. Then, the prism 9 can further adjust the propagation direction of the light to cooperate with the high beam switching mechanism 5 to form a high beam light type meeting the design requirements.

[0032] In addition, in the utility model, the reflecting cup 95 can concentrate and reflect the light emitted by the high beam lamp bead, reduce the scattering and loss of light, improve the utilization rate of light, and enhance the illumination effect of the high beam. At the same time, the cooperation of the reflecting cup 95 and the prism 9 can optimize the light path design, so that the light propagation is more accurate, and the uniformity and brightness of the high beam light type are ensured. In addition, through the reflection and focusing effect of the reflecting cup 95, the light emitted by the high beam lamp bead can be concentrated and enhanced, thereby improving the brightness and illumination distance of the high beam. In addition, the design of the reflecting cup 95 reduces the scattering of light, avoids unnecessary glare, and improves the driving safety.

[0033] ​Also, in the utility model, the integrated design of the reflecting cup 95 and the prism 9 not only enhances the high beam performance, but also simplifies the internal structure of the vehicle lamp, reduces the assembly difficulty, and improves the stability and reliability of the structure.

[0034] Further, in the embodiment, as shown in Figure 6 and Figure 7 , the prism 9 includes a first straight prism 92 arranged forwardly inclined and a second straight prism 93 arranged on the front end of the first straight prism 92 backwardly inclined, the first straight prism 92 and the second straight prism 93 are respectively composed of two obtuse angle planes, that is, the first straight prism 92 and the second straight prism 93 are designed to be folded forwardly at an obtuse angle, the top intersection of the first straight prism 92 and the second straight prism 93 is designed to be an acute angle, so that after multiple refraction and reflection of the light, the propagation direction is more accurate, the uniformity and brightness of the high beam light type are ensured, and the light emitted by the high beam lamp bead can be concentrated and enhanced, thereby improving the brightness and illumination distance of the high beam. The third straight prism 94 for enhancing the stability of the prism and the continuity of the light path is connected between the left and right ends of the first straight prism 92 and the second straight prism 93, and the high beam light shield plate 91 is arranged on the first straight prism 92 and the third straight prism 94 and fixedly connected with the support plate 42, so as to reduce the scattering of the high beam light, avoid unnecessary glare, and improve the driving safety.

[0035] In detail, in the embodiment, when the high beam light irradiates on the structure of the prism 9, the high beam light will be refracted by the obtuse angle bending part of the first straight prism 92 and the second straight prism 93 first, and the propagation direction is changed. Then, after further refraction at the acute angle intersection of the top, the high beam light will finally be guided to a specific direction. At the same time, the high beam light shield plate 91 will block part of the unnecessary light, so as to ensure that only the light refracted properly can continue to propagate.

[0036] In detail, in the embodiment, the structure design of the prism 9 through inclination, bending and connection and the like not only optimizes the light path, enhances the brightness and uniformity of the high beam, has practical optical effect, and the unique internal optical design can also add certain aesthetic appearance to the vehicle lighting. At the same time, the glare is reduced, and the driving safety is improved. In addition, the design also improves the stability of the structure and the convenience of assembly, has high practicality and reliability.

[0037] Further, in the embodiment, as shown in Figure 2 and Figure 4 , Figure 6As shown, the high beam switching mechanism 5 includes an electromagnetic valve 51 fixed on the front end of the fixed support 4 and an arc-shaped light shield 52 connected to and controlled by the electromagnetic valve 51, the smooth movement design of the arc-shaped light shield 52 makes the switching between high beam and low beam smooth and fast, which can effectively reduce the interference to the driver's sight and the road lighting effect, in the utility model, when the electromagnetic valve 51 is powered on, the arc-shaped light shield 52 can move under the action of electromagnetic force, change its position, open the light path to allow the light to pass through the prism 9 freely and project onto the front lens 3 to form a high beam mode; when the electromagnetic valve 51 is powered off, the arc-shaped light shield 52 returns to the initial position, that is, the closed state position, at this time, the upper edge of the arc-shaped light shield 52 is at the same height as the upper edge of the prism 9, which can block part of the light path, so that the high beam light cannot pass through, forming a low beam mode.

[0038] Further, in the embodiment, as shown in Figure 8 The lower end of the heat sink 6 is provided with heat dissipation fins 62 to increase the surface area of the heat sink and improve the heat dissipation efficiency, ensuring that the light source substrate can still operate at low temperature for a long time. The heat dissipation fins 62 are provided with upwardly recessed grooves 63, and the light source downward atmosphere lamp light source substrate 64 is arranged in the grooves 63, so that the vehicle lamp not only has the illumination function, but also can provide decorative atmosphere illumination, improve the appearance and user experience of the vehicle lamp, and the design of the grooves 63 fully utilizes the space of the heat dissipation fins 62, avoids occupying additional internal space of the vehicle lamp, and makes the structure of the vehicle lamp more compact. Secondly, the grooves 63 can also protect the atmosphere lamp light source substrate 64 from external impact or damage, while ensuring the stability and reliability of the light source.

[0039] Further, in the embodiment, as shown in Figures 3-6 The fixed support 4 is fixed with a Hella follow-up support 44 arranged outside the rear shell 2 of the vehicle lamp, which is used to be connected with the steering system or the suspension system of the vehicle, and can automatically adjust the beam direction of the vehicle lamp according to the steering or road conditions of the vehicle. When the vehicle turns or the road is uneven, the Hella follow-up support 44 can drive the front shell 1 and the lens 3 to adjust the angle through mechanical or electronic control, so that the light beam always irradiates the position required by the driver, realizing the follow-up function of the vehicle lamp and improving the driving safety and experience.

[0040] Further, in the embodiment, as shown in Figure 2 and Figure 4 , Figure 6 The top of the low beam reflector cup 101 is provided with a rearwardly inclined low beam light shield 102 on the inner side wall of the front end, which can block unnecessary scattered light, optimize the low beam light path, make the light more concentrated and uniform, and avoid local over-brightness or over-darkness.

[0041] Further, as shown in Figures 1-6 The limiting members 11 are arranged on the front shell 1 in a ring shape, and the user can adjust the position of the lens 3 by rotating the limiting members 11, so as to fix or release the lens 3, which makes the installation and dismounting of the lens 3 more convenient without the need of using additional tools.
