[0002] An optical module refers to a device or unit that can achieve one or more vehicle lighting functions when used alone or in combination.

[0003] In the prior art, traditional high and low beam modules usually use a lens bracket to connect the lens to other components in the module. The lens bracket can be connected to the lens by snap-fit, two-color injection molding, laser welding, etc.

[0004] However, many modules with narrow openings now have small decorative ring openings and short spacing between the upper and lower structures inside. Light emitted through the primary optical element is easily reflected on the lens bracket close to the opening, forming stray light, which requires additional patterns or leather grains to eliminate. Moreover, modules with narrow openings have higher precision requirements for each part than traditional modules and are more sensitive to tolerances between parts. The lens bracket will cause an additional part transfer tolerance between the light source and the light-emitting lens, which is not conducive to the light shape stability of mass-produced modules.

[0005] Therefore, how to improve the stability of the light output shape of the optical module is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0011] Furthermore, an anti-error notch is provided on the circuit board, and an anti-error protrusion matching the anti-error notch is provided on the receiving platform.

[0012] Furthermore, a glue overflow groove is formed on the receiving platform, and the position of the glue overflow groove corresponds to the position of the light source.

[0013] Furthermore, the secondary optical element includes an inner lens and an outer lens, and the inner lens is sandwiched between the outer lens and the heat sink connection portion.

DETAILED DESCRIPTION

[0049] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and the scope of protection of the present invention is not limited to the specific embodiments described below, and the following directions "front", "rear", "left", "right", "up" and "down" are all established with reference to the vehicle itself after the optical module is installed on the vehicle.

[0050] The utility model provides an optical module, such as Figures 1 to 6 As shown, it includes a light source assembly 1, a primary optical element 2, a secondary optical element 3 and a heat sink 4, and a receiving platform suitable for receiving the light source assembly 1 and the primary optical element 2, and a heat sink connecting portion suitable for connecting the secondary optical element 3 is formed on the heat sink 4. The light source assembly 1 and the primary optical element 2 are detachably connected on the receiving platform, and the secondary optical element 3 is detachably connected to the heat sink connecting portion, wherein the receiving platform can be a platform surface located in the middle of the heat sink 4, and the platform surface is arranged horizontally or approximately horizontally, and a connecting ear structure is provided on each side of the left and right sides of the front end of the heat sink 4, and the connecting ear structure is the heat sink connecting portion, and the front end surface of the connecting ear structure can be vertical or approximately vertical to serve as a connecting surface connected to the secondary optical element 3.

[0051] Based on the above technical solution, the optical module of the present application can use the radiator 4 as an installation platform, and install the light source assembly 1, the primary optical element 2 and the secondary optical element 3 on the radiator 4. On the one hand, the light source assembly 1, the primary optical element 2 and the secondary optical element 3 can be made more compact, so that the light emitted by the light source assembly 1 is not easily reflected on other components to form stray light in the process of passing through the primary optical element 2 to the secondary optical element 3. On the other hand, since there is no need to set up a lens bracket, the light source assembly 1, the primary optical element 2 and the secondary optical element 3 are all positioned with the radiator 4 as the positioning reference during installation. Therefore, the assembly error between the parts will be reduced, thereby reducing the transfer tolerance between the light source 12 and the lens, so that the light output stability of the optical module can be higher.

[0052] Specifically, if Figures 7 to 12 As shown, the primary optical element 2 can be configured to include an optical element connecting portion and an optical action portion 21, wherein a mounting through-hole 22 and an optical element positioning pin 23 are formed on the optical element connecting portion, and accordingly, a receiving platform mounting hole 41 matching the mounting through-hole 22 and a platform positioning hole 42 matching the optical element positioning pin 23 need to be formed on the receiving platform, so that the positioning between the primary optical element 2 and the receiving platform can be assisted by the cooperation between the optical element positioning pin 23 and the platform positioning hole 42, and after positioning, the screw 5 can pass through the mounting through-hole 22 and cooperate with the receiving platform mounting hole 41 to realize a detachable connection between the primary optical element 2 and the heat sink 4.

[0053] The optical action part 21 can be at least one of a reflector or a concentrator, and the optical action part 21 should be arranged on the front side of the optical element connecting part, so as to ensure that the light will not be interfered by the optical element connecting part after being emitted from the optical action part 21. The mounting through hole 22 and the optical element positioning pin 23 can be set to two, and an optical element positioning pin 23 and a mounting through hole 22 are respectively set on the left and right sides of the optical element connecting part to achieve better positioning and fixing effects. In addition, regardless of whether it is a reflector or a concentrator, the optical element connecting part is a thin-walled part, and the part of the optical action part 21 that is connected to the optical element connecting part is also a thin-walled part. Therefore, an optical element reinforcement rib 24 can be set between the optical element connecting part and the optical action part 21 to improve the connection strength between the optical element connecting part and the optical action part 21, and the optical element reinforcement rib 24 can also abut against the circuit board 11, and the abutting surface between the optical element reinforcement rib 24 and the circuit board 11 should preferably extend to the part of the circuit board 11 corresponding to the optical action part 21, so as to prevent the part of the circuit board 11 corresponding to the optical action part 21 from warping after the primary optical element 2 is connected and fixed.

[0054] Furthermore, the light source assembly 1 is arranged to be clamped between the primary optical element 2 and the receiving platform, so that the structure of the optical module can be made more compact, and the corresponding positioning references will overlap to a certain extent, so that the assembly error between the three will be reduced during assembly, thereby reducing the transmission tolerance of the light during the propagation process and requiring fewer screws 5. Specifically, Figures 9 to 15 As shown, the light source assembly 1 can be configured to include a circuit board 11 and at least one light source 12 provided on the circuit board 11. For example, 5 LEDs can be provided. The circuit board 11 includes a first board surface and a second board surface. The first board surface can abut against the receiving platform. The light source 12 is provided on the second board surface, so that the heat emitted by the light source 12 can be transferred to the radiator 4 along the thickness direction of the circuit board 11 for dissipation, and the heat transfer speed is faster and the heat dissipation effect is better.

[0055] The circuit board 11 may be provided with a board surface positioning hole 111, a board surface mounting hole 112 matching the mounting through hole 22, and a board surface clearance hole 113 matching the optical element positioning pin 23. Correspondingly, a receiving surface positioning pin 43 matching the board surface positioning hole 111 needs to be provided on the receiving platform. The above design enables the circuit board 11 to first achieve auxiliary positioning of the circuit board 11 through the cooperation between the board surface positioning hole 111 and the receiving surface positioning pin 43, and then, since the board surface mounting hole 112 matches the mounting through hole 22 and the receiving platform mounting hole 41, the screw 5 can pass through the mounting through hole 22 and the board surface mounting hole 112 in sequence and then cooperate with the receiving platform mounting hole 41 to achieve clamping and fixation of the circuit board 11.

[0056] Based on the setting of the above-mentioned primary optical element 2, the board surface mounting hole 112 and the board surface clearance hole 113 on the circuit board 11 are also set to two, one on each side of the left and right sides of the circuit board 11, the board surface mounting hole 112 and the board surface clearance hole 113, and the board surface positioning hole 111 can also be set to one on each side of the left and right sides of the circuit board 11, and an anti-error notch 114 can also be provided on the circuit board 11. Only one anti-error notch 114 is required, and it can be set at the junction of two adjacent board edges on the circuit board 11 or at any area that can avoid the symmetry axis or symmetry center of the circuit board 11. The receiving platform needs to be provided with an anti-error protrusion 44 that matches the anti-error notch 114, so that when installing the circuit board 11, the installation direction of the circuit board 11 can be determined by the cooperation between the anti-error notch 114 and the anti-error protrusion 44, so that installation errors are not easy to occur.

[0057] Generally, a connector needs to be provided on the second surface of the circuit board 11 for connecting to the power supply. Accordingly, a notch or through hole or other clearance structure corresponding to the connector needs to be provided on the optical element connection portion to facilitate the connection between the connector and the power supply.

[0058] In addition, a glue overflow groove 45 can be formed on the receiving platform. The position of the glue overflow groove 45 corresponds to the position of the light source 12. Thermal conductive glue needs to be applied between the circuit board 11 and the receiving platform to enhance the heat transfer effect. Thanks to the setting of the glue overflow groove 45, excess thermal conductive glue will overflow into the glue overflow groove 45, so it is not easy to overflow to the surroundings and cause pollution to surrounding components.

[0059] Furthermore, if Figure 6 as well as Figures 16 to 24 As shown, the secondary optical element 3 includes an inner lens 31 and an outer lens 32 , and the inner lens 31 is sandwiched between the outer lens 32 and the heat sink connection portion, so as to make the structure of the optical module more compact.

[0060] Specifically, the outer lens 32 includes an outer lens body 321 and an outer lens connecting ear 322. The light-emitting surface of the outer lens body 321 is a cylindrical surface, and the light-incident surface is a plane. An outer lens connecting ear 322 is provided on each side of the outer lens body 321. The outer lens connecting ear 322 is located on the light-incident side of the outer lens body 321, and an outer lens reinforcing rib 326 can be provided between the outer lens connecting ear 322 and the outer lens body 321 to enhance the overall structural strength of the outer lens 32. The outer lens 32 and the radiator 4 are generally injection molded parts, so the outer lens mounting through hole 325 and the connecting portion are provided with a connecting portion mounting hole 46 that matches the outer lens mounting through hole 325 and a connecting portion flat boss 47 that matches the outer lens flat boss 324. The outer lens flat boss 324 and the connecting portion flat boss 47 can both abut against the inner lens 31. Since the outer lens 32 and the radiator 4 are generally injection molded parts, the outer lens mounting through hole 325 and the connecting portion are provided with a connecting portion mounting hole 46 that matches the outer lens mounting through hole 325 and a connecting portion flat boss 47 that matches the outer lens flat boss 324. A raised platform surface is usually provided around the outer lens mounting hole 46 to strengthen the structure of the outer lens mounting through hole 325 and the connecting portion mounting hole 46. Therefore, it is necessary to provide an outer lens plane boss 324 and a connecting portion plane boss 47 so that the platform surface of the outer lens plane boss 324 and the raised platform surface around the outer lens mounting through hole 325 are on the same plane, and the platform surface of the connecting portion plane boss 47 and the raised platform surface around the connecting portion mounting hole 46 are on the same plane, thereby ensuring It is to be ensured that the inner lens 31 will not rotate in the up-down and left-right directions after the secondary optical element 3 is tightened and locked on the heat sink 4, and the outer lens plane boss 324, the outer lens mounting through hole 325, the connecting portion plane boss 47 and the connecting portion mounting hole 46 should be arranged so that after the secondary optical element 3 is tightened and locked on the heat sink 4, all the platform surfaces of the outer lens plane boss 324, the outer lens mounting through hole 325, the connecting portion plane boss 47 and the connecting portion mounting hole 46 are on the same plane but not on the same straight line.

[0061] Furthermore, the inner lens 31 includes an inner lens body 311 and an inner lens connecting ear 312. The light-emitting surface of the inner lens includes two planes and a curved surface sandwiched between the two planes in the up and down directions, so as to effectively reduce the dispersion of the light type. The light-entering surface is a curved surface, and when the number of light sources 12 is multiple, the light-entering surface can be a multi-segment curved surface. The number of curved surfaces is consistent with the number of light sources 12 and corresponds to the arrangement of the light sources 12. For example, if five light sources 12 are arranged in the left and right directions, the light-entering surface is a curved surface with five segments arranged in the left and right directions, and the curved surfaces are connected by rounded corners. An inner lens connecting ear 312 is provided on each of the left and right sides of the inner lens body 311, and each inner lens connecting ear 312 is formed with an inner lens positioning protrusion 313, which is connected to the inner lens The outer lens mounting through hole 325 matches the inner lens mounting through hole 314 and the inner lens positioning hole 315 matches the outer lens positioning protrusion 323. A corresponding connection part positioning hole 48 matching the inner lens positioning protrusion 313 is also formed on the radiator connection part, so that the inner lens 31 can be positioned by matching the inner lens positioning protrusion 313 with the connection part positioning hole 48. Then the outer lens mounting through hole 325, the inner lens mounting through hole 314 and the connection part mounting hole 46 correspond to each other, so that the screw 5 can pass through the outer lens mounting through hole 325 and the inner lens mounting through hole 314 in sequence and match with the connection part mounting hole 46, so that the inner lens 31 can be clamped between the outer lens 32 and the radiator connection part.

[0062] In addition, an outer lens positioning protrusion 316 may be formed on the surface of the inner lens connecting ear 312 facing the outer lens 32, and an outer lens positioning hole 327 matching the outer lens positioning protrusion 316 may be formed on the outer lens connecting ear, so that the positioning of the inner lens 31 and the outer lens 32 can be assisted by the cooperation between the outer lens positioning protrusion 316 and the outer lens positioning hole 327.

[0063] The following is an introduction to the specific structure and assembly process of the optical module of the present invention using a preferred embodiment:
