[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] See also Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of an embodiment of the automobile signal light module of the present application. Figure 2 The exploded view of an embodiment of the automobile signal light module of the present application. The automobile signal light module 10 includes a thick-walled component 1 and a heat sink 2. The thick-walled component 1 includes a thick-walled component bracket 12 and a thick-walled component 11. The thick-walled component 11 is fixed to a first side 12a of the thick-walled component bracket 12. The first side 12a is specifically the upper surface of the thick-walled component bracket 12. The heat sink 2 is fixed to a second side 12b of the thick-walled component bracket 12 along a first direction (the thickness direction of the thick-walled component 11, as shown in Z in the figure) opposite to the first side 12a. The second side 12b is specifically the lower surface of the thick-walled component bracket 12. Specifically, after the light emitted by the light source passes through the thick-walled component 11, it will be refracted and reflected according to its shape and material properties, thereby changing the propagation direction and angle of the light. The thick-walled component 11 is an optical component, and its material includes high-performance plastics such as polycarbonate (PC) or acrylic ester (PMMA); the heat sink 2 is arranged close to the light source to dissipate the heat generated when the light source emits light. Its material includes metal, which has high thermal conductivity.

[0029] The automobile signal light module 10 of the present application fixes the heat sink 2 and the thick-walled member 11 on the upper and lower sides of the thick-walled member bracket 12, that is, the thick-walled member bracket 12 serves as the bearing center of the module, and respectively carries the heat sink 2 and the thick-walled member 11. This avoids the thick-walled member 11 being directly fixed to the heat sink 2, thereby avoiding the risk of cracking of the thick-walled member 11 when the thick-walled member 11 is fixed to the metal member.

[0030] Optionally, continue to Figure 2 , Figure 3 and Figure 4 , Figure 3 1 is a bottom view of an embodiment of the vehicle signal light module 10 of the present application. Figure 4 for Figure 3 A first screw column 111 is convexly provided on one side of the thick-walled member 11 facing the thick-walled member bracket 12, and a groove 121 is provided on the first side 12a. The first screw column 111 is located in the groove 121. The automobile signal light module 10 also includes a first locking member 122. The first locking member 122 passes through the thick-walled member bracket 12 and is fixed in the first screw column 111. Figure 5 , Figure 5 for Figure 3 A schematic cross-sectional view along the BB direction. A second screw column 123 is protruding from the second side 12b, and the automobile signal light module 10 also includes a second locking member 24, which passes through the heat sink 2 and is fixed in the second screw column 123. Specifically, in the present embodiment, the first locking member 122 and the second locking member 24 are both screws, and the first screw column 111 and the second screw column 123 both have threaded holes, and the first locking member 122 passes through the through hole on the thick-walled member bracket 12 from the bottom and is threadedly connected to the first screw column 111, thereby locking the thick-walled member bracket 12 on the thick-walled member 11. The groove 121 is plug-fitted with the first screw column 111 to position the thick-walled member 11 before locking. The first locking member 122, the groove 121 and the first screw column 111 can be provided in unlimited numbers, and in the present embodiment, a total of two are provided. The second locking member 24 passes through the through hole on the heat sink 2 from the bottom and is threadedly connected to the second screw column 123, thereby locking the heat sink 2 on the thick-walled member bracket 12. The number of the second locking member 24 and the second screw column 123 is not limited, and a total of two are provided in this embodiment. The upper and lower sides of the thick-walled member bracket 12 are locked with the thick-walled member 11 and the heat sink 2 through the screw columns, which increases the strength of the module and is conducive to improving the overall vibration stability of the module.

[0031] Optionally, continue to Figure 2 The automobile signal light module 10 also includes a circuit board 3, which is fixed to the side of the heat sink 2 facing the thick-walled member 11, and a lamp bead 31 is provided on the circuit board 3. Specifically, the lamp bead 31 can be an LED lamp bead 31 as the light source of the module. When the signal light module is used for the front signal light of the automobile, each LED lamp bead 31 can include a dual core, which emits yellow light or white light respectively, and can realize the multiplexing of functions such as turning, daytime running, and side marking through the program. Continue to read Figure 5, a boss 21 is provided on the side of the heat sink 2 facing the thick-walled part 11, the boss 21 is passed through and protrudes from the circuit board 3, and the boss 21 abuts against the thick-walled part 11, so that the circuit board 3 and the lamp beads 31 are spaced apart from the thick-walled part 11. Since the lamp beads 31 protrude from the circuit board 3, when the module vibrates, the lamp beads 31 are likely to interfere and collide with the thick-walled part 11 above, causing damage to the lamp beads 31 and the thick-walled part 11; and when the lamp beads 31 are close to the thick-walled part 11, it is easy to cause the distance between the lamp beads 31 and the light incident surface of the thick-walled part 11 to be too close, so that the heat generated by the lamp beads 31 is accumulated in the gap between the circuit board 3 and the thick-walled part 11, which is difficult to dissipate, causing the temperature of the thick-walled part 11 to be too high, causing the thick-walled part 11 to melt and fail. In the present application, a boss 21 is provided on the heat sink 2, and a through hole is provided on the circuit board 3 for plugging and matching with the boss 21. Since the height of the boss 21 is greater than the sum of the thickness of the circuit board 3 and the thickness of the lamp bead 31, when the circuit board 3 is installed on the heat sink 2, the boss 21 passes through the through hole on the circuit board 3 and abuts against the light incident surface of the thick-walled part 11, so that a certain gap is maintained between the circuit board 3 and the lamp bead 31 and the light incident surface of the thick-walled part 11, thereby ensuring a smooth heat dissipation channel and avoiding interference and collision between the lamp bead 31 and the thick-walled part 11 during vibration, thereby improving the reliability of the module. In addition, the boss 21 can also play a role in positioning the circuit board 3 on the heat sink 2. Preferably, the boss 21 can be arranged close to the lamp bead 31, and a plurality of bosses can be arranged to ensure the spacing between the lamp bead 31 and the thick-walled part 11.

[0032] Optionally, continue to Figure 1 and Figure 2 The thick-walled component 1 also includes a shading cover 13, which is fixed to the side of the thick-walled component 11 away from the thick-walled component bracket 12 along the first direction Z. The shading cover 13 is used to block the external ambient light to prevent it from affecting the internal light path of the thick-walled component 11, and to prevent the light from the light source from emitting from above. The thick-walled component 11 is respectively wrapped by the shading cover 13 and the thick-walled component bracket 12 above and below to form an integral thick-walled component 1, thereby preventing the risk of light leakage inside the lamp body. Specifically, Figure 4 As shown, a surface of the thick-walled part 11 facing the shading cover 13 is provided with a shading leather texture (not marked), and shading ribs 112 are protrudingly provided on the upper and lower surfaces of the thick-walled part 11. The two shading ribs 112 are respectively located in the gap between the thick-walled part 11 and the shading cover 13, and between the thick-walled part 11 and the thick-walled part bracket 12, for blocking the light from the light source to prevent it from directly emitting out of the module from the gap.

[0033] Optionally, continue to Figure 2, a third screw column 113 is convexly provided on the side of the thick-walled component 11 facing the light shielding cover 13, and the automobile signal light module 10 also includes a third locking component 131, which passes through the light shielding cover 13 and is fixed in the third screw column 113. Specifically, the third locking component 131 is a screw, and the third screw column 113 has a threaded hole. The third locking component 131 passes through the through hole on the light shielding cover 13 and is threadedly connected to the third screw column 113, so that the light shielding cover 13 is locked on the thick-walled component 11. In this embodiment, screw columns are provided on both the upper and lower sides of the thick-walled component 11, and the lower screw column is used to lock with the thick-walled component bracket 12, and the upper screw column is used to lock with the light shielding cover 13, so that the overall strength of the thick-walled component 1 is increased, which is beneficial to vibration stability.

[0034] Optionally, see Figure 6 and Figure 7 , Figure 6 This is a top view schematic diagram of an embodiment of the automobile signal light module of the present application.

Specifically, the edges on both sides of the first mounting portion 114 extend outward to form the first mounting portion 114, and the thickness of the first mounting portion 114 is less than the thickness of the thick-walled member 11, and the edges on both sides of the second mounting portion 132 extend outward and bend to form the second mounting portion 132, and the second mounting portion 132 fits and covers the surface of the first mounting portion 114. The fourth locking member 125 is a screw, and a threaded hole is provided in the fourth screw column 124. The fourth locking member 125 passes through the second through hole 133 on the second mounting portion 132 at the edge of the light-shielding cover 13, the first through hole 115 on the first mounting portion 114 at the edge of the thick-walled member 11, and is threadedly connected with the fourth screw column 124, thereby locking the light-shielding cover 13, the thick-walled member 11 and the thick-walled member bracket 12 into a whole, saving installation space and simplifying the installation steps.

[0035] Optionally, continue to Figure 7 The second mounting portion 132 has a flange 134 extending toward the thick-walled member bracket 12, and the orthographic projection of the flange 134 on the thick-walled member 11 covers the first mounting portion 114. The flange 134 blocks the side of the first mounting portion 114 of the thick-walled member 11 to prevent light leakage and light leakage.

[0036] Optionally, see Figure 8 , Figure 8 for Figure 6 Schematic cross-sectional view along the DD direction. The light shielding cover 13 includes two first limiting portions 135 arranged at intervals, and each first limiting portion 135 has a first limiting surface 136; the thick-walled component bracket 12 includes two second limiting portions 126 arranged at intervals, and each second limiting portion 126 has a second limiting surface 127; the first limiting surface 136 and the second limiting surface 127 are both step surfaces, and the second limiting surface 127 is in contact with the first limiting surface 136. Specifically, the two first limiting portions 135 and the two second limiting portions 126 are arranged at intervals along the second direction (left-right direction, as shown in Y in the figure) and the third direction (front-back direction, as shown in X in the figure), and are located at the end where light is emitted. The mutually in contact first limiting portions 135 and second limiting portions 126 are used to limit each other in the first direction Z and the second direction Y, that is, to guide in the third direction X to ensure the assembly accuracy of the thick-walled component 1. The two first limiting portions 135 and the two second limiting portions 126 together form a space for accommodating a portion of the thick-walled component 11 .

[0037] Optionally, see Fig. 9 , Fig. 9 This is a partial cross-sectional schematic diagram of the light-emitting end of the automobile signal light module of the present application. The automobile signal light module 10 also includes a main decorative ring 4, which has a mounting hole 41.

The first limiting rib 137 and the second limiting rib 128 are mutually limited with the main decorative ring 4 in the first direction Z and the third direction X, so that the relative displacement of the main decorative ring 4 and the thick-walled component 1 in the first direction Z is limited to within 0.3mm, and the relative displacement in the third direction X is limited to within 0.5mm. The relative position of the main decorative ring 4 and the thick-walled component 11 is guaranteed, and the risk of interference and grinding between the thick-walled component 11 and the main decorative ring 4 during vibration is reduced.
