Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-7 A dual TIR prism dual-light lens comprises a light source, a lens 2, a fixing bracket 3, a heat dissipation structure assembly 4, a low-beam reflector cup 5, a dimming switching mechanism 6, a high-beam TIR prism 7 and a module driver 8, wherein the light source comprises a low-beam module 11 and a high-beam module 12, the high-beam TIR prism 7 is arranged behind the dimming switching mechanism 6 and above the lamp bead of the high-beam module 12, a direct light board 33 is arranged on the fixing bracket 3, the lens 2 comprises a low-beam main lens, a TIR prism light-collecting lens and a high-beam auxiliary lens, the low-beam main lens is located in the area below the lens 2, the TIR prism light-collecting lens and the high-beam auxiliary lens are located in the area above the lens 2, and the fixing bracket 3 is arranged on the front side of the heat dissipation assembly.

[0023] The utility model realizes the total reflection effect and the refraction processing of light through the high-beam TIR prism 7, and can obtain brighter and clearer lighting effects without increasing additional energy consumption, providing better visual protection for the driver, and also reducing the energy consumption of the vehicle, so that the product can maximize the utilization rate of the light source light efficiency under the same power; at the same time, the dual direct laser or LED practical high-beam fill light function generated by the direct light panel 33 is used to ensure the lighting effect, and the product has good stability. In actual use, this high-beam fill light function can quickly provide powerful lighting support when needed, such as when encountering emergencies at night or requiring a farther field of view, it can play a role in time to ensure driving safety, further reflecting its high practicality.

[0024] like Figure 2As shown, the fixing bracket 3 in the embodiment of the utility model is provided with two positioning posts 31 and a plurality of ribs 32 for aligning and installing the lens 2, wherein the two positioning posts 31 play a key positioning role, they can ensure that the lens 2 can quickly and accurately find the correct installation position when installing, and achieve precise alignment, so as to avoid deviation in the installation of the lens 2 and ensure the accuracy of light refraction and reflection. The plurality of ribs 32 mainly play the role of enhancing support and fixing. These ribs 32 are evenly distributed on the fixing bracket 3, they can share the pressure and force on the lens 2, so that the lens 2 is more stable and reliable after installation, and will not shake or shift easily. During the driving process of the vehicle, even if it encounters bumps and other situations, the lens 2 can always maintain a good position state, so as to continuously and stably exert its optical performance, and ensure that the headlight can provide high-quality and stable lighting effects. Through the synergistic effect of the positioning posts 31 and the ribs 32, the convenience, accuracy and stability of the installation of the lens 2 are achieved.

[0025] like Figure 3 and Figure 4 As shown, the light-changing switching mechanism 6 in the utility model includes a base 61, a solenoid valve mechanism 62 fixedly mounted on the base 61, and a baffle 63 axially connected to the base 61. The base 61 provides a stable support foundation for the entire light-changing switching mechanism 6. The solenoid valve mechanism 62 is firmly fixed on the base 61, and contains precise electromagnetic drive components and telescopic rods. When it is necessary to switch between low beam and high beam, the solenoid valve mechanism 62 will receive a corresponding electrical signal, thereby driving the telescopic rod to perform telescopic movement, and the baffle 63 is connected to the base 61 through a specific axial connection structure. The baffle 63 can flexibly swing around the axis. When the telescopic rod moves, it will directly Used for the baffle 63, driving the baffle 63 to swing accordingly. Specifically, when it is necessary to switch to the high beam mode, the telescopic rod is extended to push the baffle 63 to swing to a specific position, so that the light can be projected according to the designed path of the high beam, thereby achieving the high beam effect; and when it is necessary to switch back to the low beam mode, the telescopic rod is retracted, and the baffle 63 swings back to the corresponding low beam position to achieve the state switching of the low beam.

[0026] like Figure 1 As shown, the heat dissipation structure assembly 4 in the present invention includes a main body heat sink 41 , a fan 42 , a lossless bracket 43 and a drive cover 44 , and the module driver 8 is fixedly mounted on the main body heat sink 41 .

[0027] like Figure 5As shown, a first alignment column 411 for aligning and installing the low beam module 11 and a second alignment column 412 for aligning and installing the high beam module 12 are provided on the main body radiator 41 of the utility model, and the first alignment column 411 and the second alignment column 412 are located on the same mounting surface, and the first alignment column 411 and the second alignment column 412 are asymmetrically arranged, the low beam module 11 is aligned and installed on the main body radiator 41 by the first alignment column 411, and the high beam module 12 is aligned and installed on the main body radiator 41 by the second alignment column 412, and then fixed by screws, so that the low beam module 11 and the high beam module 12 are installed on the same mounting plane of the main body radiator 41, and the installation position is prevented from being easily mistaken or offset, so as to improve the accuracy and efficiency of product assembly.

[0028] like Figure 6 As shown, the main body radiator 41 of the utility model is also provided with a third alignment column 413 for aligning the low-beam reflector cup 5. The third alignment column 413 aligns the low-beam reflector cup 5 with the low-beam module 11 inside and outside, thereby ensuring that the low-beam reflector cup 5 and the low-beam module 11 are in corresponding positions, so that they can be used in conjunction with each other. The heat dissipation structure component 4 is composed of multiple important parts, among which the main body radiator 41 occupies a key position. It has a large heat dissipation area and good heat conduction performance, and can effectively absorb and conduct the heat generated when the headlight is working. The fan 42 is closely combined with the main body radiator 41. The fan 42 generates airflow by rapid rotation, accelerates the flow of air, and quickly takes away the heat on the main body radiator 41, further enhancing the heat dissipation effect. The lossless bracket 43 plays a role of stable support and connection, fixing the various components tightly together to ensure the stability of the entire heat dissipation structure assembly 4. The drive cover 44 also plays an indispensable role. It provides protection for related drive components, and the module driver 8 is firmly and accurately fixed on the main radiator 41. This installation method ensures that the module driver 8 can operate stably during operation. At the same time, the main radiator 41 can promptly conduct the heat generated by the module driver 8 to avoid performance or failure due to overheating. Through the synergistic effect of the main radiator 41, the fan 42, the lossless bracket 43 and the drive cover 44, an efficient and stable heat dissipation structure assembly 4 is jointly constructed, which provides reliable guarantee for the continuous and normal operation of the car lights.

[0029] like Figure 7As shown, the fan 42 in the embodiment of the utility model is fixedly installed on the main radiator 41 by a drive cover 44 and screws, and the fan 42 and the main radiator 41 form a vertical ventilation channel. When the fan 42 starts to run, the strong airflow it generates can flow quickly and efficiently along this vertical ventilation channel, and the air is quickly sucked in and passes through the radiator body, quickly taking away the accumulated heat therein, and then discharged to the external environment. The formation of this vertical ventilation channel greatly optimizes the heat dissipation path. The heat that might originally flow in a circuitous way inside the radiator can now be more directly and quickly brought out by the airflow, reducing the possibility of heat accumulation and retention, so that the headlights can maintain a suitable temperature even when working for a long time, ensuring the stable performance and service life of the headlights, and providing reliable support for the safe driving of the vehicle.
