[0033] The thick wall light guide mechanism 100 of the utility model, through circuit board 2 and thick wall lens 3 are installed in the top of mounting bracket 1, and thick wall lens 3 is supported on support frame 11 by using support frame 11, keep the stability of thick wall lens 3, prevent the non-uniformity of light output caused by thick wall lens 3 shaking;By setting the evenly distributed diverging patterns on the first diverging surface 32 and the second diverging surface 33 of the thick wall lens 3, the light beam of the lamp source 21 can be effectively diverged twice, so that the light beam can be more uniformly shot forward after passing through the first diverging surface 32 and the second diverging surface 33, thereby improving the uniformity of the overall light emission of the vehicle lamp;And the first diverging surface 32 is arc surface, and the extension direction thereof is consistent with the distribution direction of the plurality of lamp sources 21, so as to ensure that the light beam emitted by each lamp source 21 can be effectively captured and shot to the first diverging surface 32, in addition, the first diverging surface 32 is inclined from top to bottom to rear relative to the top surface 31, changes the transmission path of the light beam of the lamp source 21, increases the flexibility of the arrangement of the lamp source 21, and the lamp source 21 does not need to be arranged directly towards the front, so that the light emission is more uniform;Compared with the structure of using multiple thick wall lenses 3, only a single thick wall lens 3 is used in the utility model, which reduces the weight of the entire thick wall light guide mechanism 100, meets the requirement of light weight, and realizes the stability of the thick wall lens 3 through the support frame 11, simplifies the assembly process, is easier to install, and has lower cost.

[0034] Specifically, each lamp source 21 is located directly below the first diverging surface 32, so that the light beam emitted by the lamp source 21 can enter the thick wall lens 3 more quickly, thereby increasing the utilization rate of the light beam of the lamp source 21.

[0035] Further, the first diverging surface 32 is arranged at an angle of 45°, so that the light beams emitted by the light source 21 towards the first diverging surface 32 are converted into horizontal light beams after being refracted by the first diverging surface 32.

[0036] It should be noted that the light source 21 is an LED light source 21 in the prior art.

[0037] In an embodiment, the bottom surface of the thick-walled lens 3 is formed with light collectors 34 protruding downward at positions corresponding to the light sources 21, and the bottom surface of each light collector 34 is formed with a downwardly open groove, each light source 21 is located below the corresponding opening, and the size of the opening is greater than the size of the light source 21; the light beams emitted by each light source 21 are collected by the corresponding light collector 34 and then emitted towards the first diverging surface 32.

[0038] As can be understood, due to the light beams emitted by the light source 21 towards the surrounding, the light collectors 34 protruding downward arranged on the bottom surface of the thick-walled lens 3 can effectively capture the light beams emitted by the light source 21, and then converge the light beams and emit them towards the first diverging surface 32, thereby reducing the loss of light beams during propagation and improving the utilization rate of light, so as to enhance the overall brightness of the vehicle lamp; each light source 21 corresponds to a light collector 34, and the bottom of the light collector 34 is provided with a downwardly open groove, which can accurately guide the light emitted by the light source 21 into the light collector 34, ensuring that the light propagates along the preset path and avoiding disordered scattering of the light.

[0039] Further, the outer side surface of each light collector 34 is a total reflection surface, the light beams emitted towards the outer side surface can be reflected towards the first diverging surface 32 by the outer side surface; the groove bottom of each groove is protruded downward to form a convex lens structure or a Fresnel lens structure, and the light beams emitted towards the groove bottom can be refracted by the groove bottom and then emitted towards the first diverging surface 32.

[0040] In an embodiment, the bottom of the thick-walled lens 3 is provided with a connecting block 34 extending rearward, the top of the mounting frame 1 is provided with a threaded hole, and the circuit board 2 and the connecting block 34 are provided with through holes at positions corresponding to the threaded hole, and the circuit board 2 and the thick-walled lens 3 are mounted on the mounting frame 1 by means of bolts passing through the through holes and being screwed with the threaded hole.

[0041] As can be understood, by arranging the connecting block 34 extending rearward on the bottom of the thick-walled lens 3 and fixing the circuit board 2 and the thick-walled lens 3 on the mounting frame 1 by means of bolts, the connection strength between the thick-walled lens 3 and the mounting frame 1 can be significantly enhanced, and each bolt can pass through the connecting block 34 and the circuit board 2 at the same time, so that the circuit board 2 and the thick-walled lens 3 can be mounted on the mounting frame 1 at the same time, thereby simplifying the assembly process and reducing the structural complexity; and the mounting mode by means of bolts also facilitates the disassembly of the circuit board 2 and the thick-walled lens 3.

[0042] Further, at least two connecting blocks 34 can be provided, and each connecting block 34 is provided with a through hole, so as to be fixed by a bolt.

[0043] In an embodiment, the bottom of the connecting block 34 is provided with a support column 35, and the bottom of the support column 35 is supported on the top of the circuit board 2, so that the bottom of the thick-wall lens 3 is spaced apart from the top of the circuit board 2 to form a first heat dissipation gap.

[0044] It can be understood that, by providing the support column 35 at the bottom of the connecting block 34, the first heat dissipation gap is formed between the connecting block 34 and the circuit board 2 through the support column 35, so as to facilitate heat dissipation and cooling of the light source 21 on the circuit board 2 during continuous lighting, so as to maintain the normal operation of the light source 21.

[0045] It can be seen that one end of the thick-wall lens 3 is supported by the support column 35, and the other end is supported by the support frame 11, so that the stability of the thick-wall lens 3 is better.

[0046] In an embodiment, the support frame 11 is provided with a support plate 12 extending forward at the top of the side close to the second diverging surface 33, and the bottom of the thick-wall lens 3 is supported on the support plate 12; the bottom of the thick-wall lens 3 is provided with a limiting convex strip 36, and the limiting convex strip 36 is abutted with the support frame 11 on the side of the support frame 11.

[0047] It can be seen that the support frame 11 is provided with the support plate 12 extending forward at the top, and the bottom of the thick-wall lens 3 is directly supported on the support plate 12. This design provides a stable support point for the thick-wall lens 3, ensures that it will not tilt or shake after installation, and enhances the structural stability of the entire thick-wall lens 3; the bottom of the thick-wall lens 3 is provided with the limiting convex strip 36, and the limiting convex strip 36 is abutted with the support frame 11. This design can effectively limit the lateral movement of the thick-wall lens 3, and avoid the lateral displacement of the thick-wall lens 3 due to vibration or impact during vehicle driving.

[0048] It should be noted that, when in the vehicle lamp, the lamp shell of the vehicle lamp and the support plate 12 are respectively supported on the upper and lower sides of the thick-wall lens 3, so as to clamp the thick-wall lens 3, which can further maintain the stability of the thick-wall lens 3 in the vehicle lamp.

[0049] In an embodiment, the support frame 11 is provided with a limiting gap 13 away from the side of the second diverging surface 33, and the circuit board 2 is provided with a limiting portion 22 corresponding to the position of the limiting gap 13, the limiting portion 22 extends into the limiting gap 13, so that the bottom of the circuit board 2 is spaced apart from the top of the mounting frame 1 to form a second heat dissipation gap.

[0050] Understandably, by opening the limiting gap 13 on the support frame 11, and setting the limiting part 22 on the circuit board 2, the circuit board 2 can be accurately positioned and installed, and the circuit board 2 can be prevented from moving during installation, thereby simplifying the installation process.

[0051] In an embodiment, the support frame 11 is provided with an opening 14 adjacent to one side of the second diverging surface 33, and the opening 14 is in communication with the second heat dissipation gap.

[0052] Understandably, by setting the opening 14 adjacent to one side of the support frame 11 and the second diverging surface 33, and making the opening 14 in communication with the second heat dissipation gap, the air flow channel is further increased, the heat dissipation gap and the exchange path of the outside air are increased, and the heat dissipation efficiency can be significantly improved.
