DETAILED DESCRIPTION

[0027] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] Please refer to Figure 1 and Figure 2 , Figure 1 is a stereoscopic diagram of a multifunctional light path illumination system according to an embodiment of the present invention; Figure 2It is an exploded diagram of a multifunctional light path illumination system according to an embodiment of the present invention. As shown in the figure, a multifunctional light path illumination system comprises a lens assembly 10, the lens assembly 10 comprises a low beam lens 11, a high beam lens 12, two position lenses 13, and a panel 14 connecting the four lenses, wherein the two position lenses 13 are opposite to each other; a bracket 20 for snapping the lens assembly 10, the bracket 20 exposing the low beam lens 11, the high beam lens 12, and the two position lenses 13; a mounting plate 30 connected to the bracket 20, the mounting plate 30 having a notch 31 facing the high beam lens 12; a heat dissipation module 40 disposed on the mounting plate 30; a first light source 61 disposed on the mounting plate 30 and facing the low beam lens 11 and the two position lenses 13; and a second light source 62 disposed in the notch 31 and mounted on the heat dissipation module 40, the second light source 62 reflecting light to the high beam lens 12 through a reflection bowl 50.

[0029] In one embodiment of the present invention, a low beam lens 11, a high beam lens 12, and two position lenses 13 are combined and connected as one through a panel 14. At the same time, the two position lenses 13 are opposite to each other to realize the integration of multifunctional high beam, low beam and position width indicator, avoiding the excessive space occupied by separate settings. The bracket 20 snaps onto the panel 14 to achieve the fixation of the lens assembly 10. The mounting plate 30 is installed with a first light source 61 facing the lens assembly 10 to achieve low beam and position width indicator light illumination. In addition, a heat dissipation module 40 is arranged behind the mounting plate 30, and a second light source 62 is added while dissipating heat. The reflective bowl 50 is used to reflect light through the notch 31 of the mounting plate 30 to the high beam lens 12, which is convenient for light concentration, increases the emission length, and realizes high beam illumination. In addition, the first light source 61 and the second light source 62 are arranged separately, which also avoids the high heat concentration generated by the two being adjacent to each other. They are respectively installed on both sides of the heat dissipation module 40 to improve the heat dissipation efficiency, do not affect each other, and are practical and convenient.

[0030] It is worth mentioning that both the first light source 61 and the second light source 62 include a circuit substrate 63, and the circuit substrate 63 is equipped with LED chips 64 corresponding to four lenses. The LED chips 64 can avoid the high energy consumption of halogen bulbs, save energy, and at the same time, the light intensity is uniform and concentrated, which greatly improves the recognition of the vehicle when driving in the dark.

[0031] Please refer to Figure 3 , Figure 3Schematic diagram of a bracket 20 according to an embodiment of the present invention. The bracket 20 includes a cover 21 sleeved on the lens assembly 10, the cover 21 covers the panel 14 and exposes the low beam lens 11, the high beam lens 12 and the two position lenses 13; an active buckle 22 arranged around the inner wall of the cover 21 and buckled on the panel 14; and a connecting bracket 23 arranged around the cover 21, and the connecting bracket 23 is connected to the mounting plate 30 by bolts. In an embodiment of the present invention, the bracket 20 is sleeved on the lens assembly 10 by using the cover 21, and its panel 14 is buckled inside the cover 21, while the low beam lens 11, the high beam lens 12 and the two position lenses 13 are exposed, forming a limit of the lens assembly 10, the panel 14 is fixed, and the lens is displayed outside to achieve normal operation. In addition, the active buckle 22 is located on the inner wall of the cover 21, and stops against the panel 14, thereby achieving the fixation of the entire lens assembly 10 and improving the stability of the vehicle during use. The connecting bracket 23 is used to connect the mounting plate 30 and the heat dissipation module 40, which facilitates the connection and improves the scope of use.

[0032] It is worth mentioning that please continue to refer to Figure 4 , Figure 4 2 is a schematic diagram of an active buckle 22 in one embodiment of the present invention. The active buckle 22 is disposed in the notch 24 of the inner wall of the cover 21, and includes a fixed portion 221 on the side of the notch 21 away from the lens assembly 10, an inclined portion 222 connected to the fixed portion 221, the inclined portion 222 is inclined toward the center of the cover 21, and forms a predetermined angle θ with the fixed portion 221, and a protruding buckle 223 disposed on the inner side of the inclined portion 222, one side of the protruding buckle 223 abuts against the panel 14, and the other side is provided with an inclined surface 224. In one embodiment of the present invention, the active buckle 22 is located in the notch 24, and the notch 24 is provided as a notch in the side wall of the cover 21 with a size slightly larger than that of the active buckle 22, so as to achieve fine adjustment of the active buckle 22. In detail, the active buckle 22 includes a fixed portion 221 disposed in the notch 21, the fixed portion 221 is connected to the inclined portion 222, and the inclined portion 22 is provided with a protruding buckle 223 facing the center of the cover 21. When installing the lens assembly 10, the lens assembly 10 is pushed in from the rear of the cover 21. When passing through the active buckle 22, the protruding buckle 223 with the inclined surface 224 is pushed outward by the inclined portion 222, so that the lens assembly 10 pushes against the protruding buckle 223 and passes over the active buckle 22. In this way, the front side of the protruding buckle 223 can stop against the panel 14, and the lens assembly 10 is fixed in cooperation with the end face of the cover 21. The structure is simple, the installation is convenient, and the stability of the optical path during the driving of the vehicle is improved.

[0033] In addition, in one embodiment of the present invention, the predetermined angle θ is set to 4° to 7°. After multiple tests, at 4°, the bending amount is the smallest, and it is a little difficult to push the lens assembly 10; while at 7°, the bending amount is too large, which easily causes stress concentration on the protruding buckle portion 223 and affects the structural rigidity. Therefore, when the predetermined angle θ is set to 4° to 7°, the stability of the buckle can be better guaranteed.

[0034] Please refer to Figure 5 , Figure 5 : is a schematic diagram of a heat dissipation module 40 according to an embodiment of the present invention. The heat dissipation module 40 includes a mounting platform 41 for guiding the notch 31 of the mounting plate 30, and heat dissipation fins 42 arranged at the bottom and both sides of the mounting platform 41; wherein the mounting platform 41 is higher than the lower side of the notch 31, and is used to install the second light source 62. It should be understood that the lens assembly 10, under the cooperation of the first light source 61 and the second light source 62, emits light with high identification intensity, which will inevitably generate a large amount of heat, and at this time, the heat dissipation module 40 is connected to install the first light source 61 and the second light source 62 to dissipate most of the heat. The second light source 62 required by the high-beam lens 12 is fixed by the mounting platform 41, and the heat dissipation fins 42 are directly used for heat dissipation, and the first light source 61 is transitionally connected through the mounting plate 30, which can also achieve heat dissipation, which is convenient and practical. It is worth mentioning that the mounting platform 41 is higher than the notch 31, so that the heat of the first light source 31 flows through the notch 31, increasing the air contact efficiency, and the heat dissipation is faster, thereby increasing the service life of the light source and avoiding overheating damage.

[0035] Next, please refer to Figure 6 and Figure 7 , Figure 6 is a schematic diagram of a gusset plate 70 according to an embodiment of the present invention, Figure 7 It is a schematic diagram of the connection between the reflective bowl 50 and the buckle plate 70 of one embodiment of the present invention. As shown in the figure, the reflective bowl 50 is fixed to the heat dissipation module 40 through the buckle plate 70 to cover the second light source 62. The buckle plate 70 is connected to the slide rails of the mounting platform 41 on both sides and fixed to the mounting platform 41 by screws; the buckle plate 70 has an extension portion 72 extending along the direction of the notch 31, the extension portion 72 exceeds the notch 31, and the bottom of the extension portion 32 has an undercut 73, and the undercut 73 is buckled with the mounting platform 41. In this embodiment, it should be understood that the surface of the reflective bowl 50 needs to be aluminum-plated to achieve light reflection, and the heat dissipation module 40 is also made of aluminum, and the two are prone to interference. Therefore, the buckle plate 70 is added for isolation, and it also has the effect of stable support. It is worth mentioning that there are tracks 71 on both sides of the buckle plate 70, which can be connected to the slide rails of the mounting platform 41 to avoid inaccurate positioning of the reflective bowl 50 and affect the transmission of light. In addition, the buckle plate 70 has an extension portion 72 along the transmission direction of the notch 31 to prevent the light from being dissipated after reflection and affecting the light concentration. The bottom of the extension portion 32 has an undercut 73 that can be snapped onto the mounting platform 41, which is stable and effective.

[0036] Please continue to refer to Figure 7 The reflective bowl 50 and the buckle plate 70 respectively have relative positioning posts 80, which are engaged with each other through the positioning posts 80 to achieve accurate positioning, improve installation efficiency, and do not require too many steps to check the transmittance.
