Description
Technical Field
[0001] The present application relates to the field of automobile lighting, and in particular to a baffle-free high and low beam lens module. Background Art
[0002] For driving safety, national regulations clearly stipulate that low beam headlights must have a clear light and dark cut-off line, that is, the light projection of the headlights should appear on the road with low light on the left and high light on the right, so as to avoid affecting the field of vision of drivers of oncoming vehicles.
[0003] The cut-off line is formed by the light emitted by the light source after being blocked by a specific optical structure. The conventional high and low beam lens design is composed of a condenser (or reflector) plus a steel sheet (or solenoid valve baffle) plus a lens. The addition of a steel sheet will cause an obvious black line to appear at the junction of the high and low beams, affecting the driving experience. In addition, the solenoid valve structure is expensive and has abnormal noise. Utility Model Content
[0004] In order to reduce or eliminate the black line at the junction of high and low beams and improve the visual experience of night driving, the present application provides a baffle-free high and low beam lens module.
[0005] The present application provides a baffle-free high and low beam lens module, which adopts the following technical solution:
[0006] A baffle-free high and low beam lens module comprises a light source module, a reflection module and a lens module. The reflection module comprises a reflection integrated board and a low beam reflection mechanism and a high beam reflection mechanism arranged on the reflection integrated board. The low beam reflection mechanism comprises a common reflection component and an exclusive reflection component. A cut-off line forming mechanism for forming a cut-off line contour shape is provided on a side of the exclusive reflection component close to the high beam reflection mechanism.
[0007] By adopting the above technical solution, when it is necessary to turn on the low beam, the shared reflector and the exclusive reflector work together to reflect the light projected by the light source module to the lens module, and then focus the lens module to form a low beam spot. Since the light passes through the exclusive reflector and then passes through the cutoff line forming mechanism, a clear cutoff line outline will appear after the low beam is turned on. When it is necessary to turn on the high beam, the high beam reflection mechanism and the shared reflector work together to reflect the light projected by the light source module to the lens module, and then focus the lens module to form a high beam spot. After turning on the high beam, the exclusive reflector does not reflect, which is conducive to improving or eliminating the black line at the junction of the high and low beams, thereby improving the visual experience of night driving.
[0008] Optionally, the exclusive reflector includes a left exclusive reflector and a right exclusive reflector arranged on the reflective integrated board, and the cut-off line forming mechanism includes a left cut-off line forming groove arranged corresponding to the left exclusive reflector and a right cut-off line forming groove arranged corresponding to the right exclusive reflector, and the left cut-off line forming groove and the right cut-off line forming groove are both arranged on the reflective integrated board.
[0009] By adopting the above technical solution, when the low beam headlight is turned on, the light reflected by the left exclusive reflector passes through the left cut-off line forming groove and the corresponding lens module to focus to form the left contour of the cut-off line, and the light reflected by the right exclusive reflector passes through the right cut-off line forming groove and the corresponding lens module to focus to form the right contour of the cut-off line.
[0010] Optionally, the common reflector includes two common reflectors arranged on a reflective integrated board.
[0011] By adopting the above technical solution, the brightness of automobile lighting can be effectively guaranteed and driving safety can be improved.
[0012] Optionally, the high-beam reflection mechanism includes two high-beam reflectors arranged on a reflection integrated board.
[0013] By adopting the above technical solution, the lighting brightness and lighting range of the car when the high beam is turned on can be effectively guaranteed, further improving driving safety.
[0014] Optionally, the light source module includes a PCB board and low beam lamp beads and high beam lamp beads arranged on the PCB board, and the low beam lamp beads are arranged correspondingly to the low beam reflection mechanism, and the high beam lamp beads are arranged correspondingly to the high beam reflection mechanism.
[0015] By adopting the above technical solution, when the low beam is turned on, all the low beam lamp beads are turned on, and all the high beam lamp beads are turned off. The light generated by the low beam lamp beads is reflected by the corresponding common reflector and the exclusive reflector and then focused by the lens module to form a low beam spot, thereby ensuring the illumination brightness and illumination range of the low beam. When the high beam is turned on, all the high beam lamp beads are turned on, the low beam lamp beads corresponding to the common reflector are turned on, and the low beam lamp beads corresponding to the exclusive reflector are turned off. The above light is reflected by the exclusive reflector and the high beam reflection mechanism and then focused by the lens module to form a high beam spot, thereby ensuring the illumination brightness and illumination range of the high beam.
[0016] Optionally, the lens module includes an external bracket and a low beam lens and a high beam lens arranged on the external bracket, and the low beam lens is arranged corresponding to the low beam reflection mechanism, and the high beam lens is arranged corresponding to the high beam reflection mechanism.
[0017] By adopting the above technical solution, it is ensured that the light can be focused to a preset area after being reflected by the low beam reflection mechanism and the high beam reflection mechanism, thereby ensuring the illumination brightness of the high and low beams.
[0018] Optionally, a heat sink is provided on the light source module.
[0019] By adopting the above technical solution, the module is guaranteed to have good heat dissipation performance and the service life of the light source module is increased.
[0020] In summary, the present application includes at least one of the following beneficial technical effects:
[0021] 1. Through the arrangement of the shared reflector, the exclusive reflector and the cut-off line forming mechanism, when the low beam light needs to be turned on, the shared reflector and the exclusive reflector work together to reflect the light projected by the light source module to the lens module, and then focus the light through the lens module to form a low beam spot. Since the light passes through the exclusive reflector and then passes through the cut-off line forming mechanism, a clear cut-off line outline will appear after the low beam light is turned on. When the high beam light needs to be turned on, the high beam reflection mechanism and the shared reflector work together to reflect the light projected by the light source module to the lens module, and then focus the light through the lens module to form a high beam spot. After the high beam light is turned on, the exclusive reflector does not reflect, which is conducive to improving or eliminating the black line at the junction of the high and low beams, thereby improving the visual experience of night driving.
[0022] 2. Through the setting of the radiator, the module is guaranteed to have good heat dissipation performance and the service life of the light source module is improved.
[0023] 3. There is no baffle design in the present application. The cutoff line forming mechanism is integrated with the reflective module, and the high and low beam spots are formed by the lens module. Compared with forming the cutoff line profile by installing a baffle, the present application simplifies the optical parts and is beneficial to reducing the size of the incident surface of the lens module, thereby achieving the purpose of lightweighting and reducing the cost of the module.

DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-5 , further details of this application are given.
[0031] Example:
[0032] The present application embodiment discloses a high and low beam lens module without a baffle. Figure 1 and Figure 2 A baffle-free high and low beam lens module comprises a light source module 1, a reflection module 2 and a lens module 3. The reflection module 2 comprises a reflection integrated board 211 and a low beam reflection mechanism 21 and a high beam reflection mechanism 22 arranged on the reflection integrated board 211. The low beam reflection mechanism 21 comprises a shared reflection member 212 and an exclusive reflection member 213. A cut-off line forming mechanism 23 for forming a cut-off line contour shape is arranged on one side of the exclusive reflection member 213 close to the high beam reflection mechanism 22.
[0033] When the low beam light needs to be turned on, the shared reflector 212 and the exclusive reflector 213 work together to reflect the light projected by the light source module 1 to the lens module 3, and then focus the light through the lens module 3 to form a low beam spot. Since the light passes through the exclusive reflector 213 and then passes through the cutoff line forming mechanism 23, a clear cutoff line outline will appear after the low beam light is turned on. When the high beam light needs to be turned on, the high beam reflection mechanism 22 and the shared reflector 212 work together to reflect the light projected by the light source module 1 to the lens module 3, and then focus the light through the lens module 3 to form a high beam spot. After the high beam light is turned on, the exclusive reflector 213 does not reflect, which is conducive to improving or eliminating the black line at the junction of the high and low beams, thereby improving the visual experience of night driving.
[0034] Reference Figure 2 and Figure 3The exclusive reflector 213 includes a left exclusive reflector 2131 and a right exclusive reflector 2132 integrally formed on the reflective integrated board 211, and the cutoff line forming mechanism 23 includes a left cutoff line forming groove 231 corresponding to the left exclusive reflector 2131 and a right cutoff line forming groove 232 corresponding to the right exclusive reflector 2132, and the left cutoff line forming groove 231 and the right cutoff line forming groove 232 are integrally formed on the reflective integrated board 211. When the low beam is turned on, the light reflected by the left exclusive reflector 2131 is focused by the left cutoff line forming groove 231 and the corresponding lens module 3 to form the left contour of the cutoff line, and the light reflected by the right exclusive reflector 2132 is focused by the right cutoff line forming groove 232 and the corresponding lens module 3 to form the right contour of the cutoff line.
[0035] Reference Figure 2 The common reflector 212 includes two common reflectors 2121 integrally formed on the reflective integrated board 211, and the high-beam reflector mechanism 22 includes two high-beam reflectors 221 integrally formed on the reflective integrated board 211. In this way, the brightness and lighting range of the automobile lighting can be effectively guaranteed, and the safety of night driving can be improved. In this embodiment, the reflective integrated board 211 is an aluminum-plated PC board.
[0036] Reference Figure 1 and Figure 4 The light source module 1 includes a PCB board 11 and a low beam lamp bead 12 and a high beam lamp bead 13 fixed on the PCB board, and the low beam lamp bead 12 is arranged corresponding to the low beam reflection mechanism 21, and the high beam lamp bead 13 is arranged corresponding to the high beam reflection mechanism 22. In this embodiment, four low beam lamp beads 12 are arranged, two of which are arranged corresponding to the common reflector 2121, one of which is arranged corresponding to the left exclusive reflector 2131, and the remaining one is arranged corresponding to the right exclusive reflector 2132; two high beam lamp beads 13 are arranged.
[0037] Reference Figure 1 and Figure 5 In order to ensure that the light can be focused on the preset area after being reflected by the low beam reflection mechanism 21 and the high beam reflection mechanism 22, and to ensure the illumination brightness of the high and low beams, the lens module 3 includes an outer bracket 31 and a low beam lens 32 and a high beam lens 33 fixed on the outer bracket 31, and the low beam lens 32 is arranged corresponding to the low beam reflection mechanism 21, and the high beam lens 33 is arranged corresponding to the high beam reflection mechanism 22. In this embodiment, four low beam lenses 32 are arranged, and two high beam lenses 33 are arranged; the material of the outer bracket 31 is PC; the material of the low beam lens 32 and the high beam lens 33 are both transparent PC.
[0038] Reference Figure 1, a heat sink 4 is mounted on the light source module 1, and the heat sink 4 is detachably fixed to the lower side of the PCB board 11 by bolts. In this embodiment, the heat sink 4 is an aluminum heat sink 4, which ensures that the module has good heat dissipation performance, thereby improving the service life of the light source module 1.
[0039] The implementation principle of a baffle-free high and low beam lens module in the embodiment of the present application is as follows: when the low beam needs to be turned on, the shared reflector 212 and the exclusive reflector 213 work together to reflect the light projected by the light source module 1 to the lens module 3, and then focus the light through the lens module 3 to form a low beam spot. Since the light passes through the exclusive reflector 213 and then passes through the cutoff line forming mechanism 23, a clear cutoff line outline will appear after the low beam is turned on. When the high beam needs to be turned on, the high beam reflection mechanism 22 and the shared reflector 212 work together to reflect the light projected by the light source module 1 to the lens module 3, and then focus the light through the lens module 3 to form a high beam spot. After the high beam is turned on, the exclusive reflector 213 does not perform a reflection effect, which is conducive to improving or eliminating the black line at the junction of the high and low beams, thereby improving the visual experience of night driving.
[0040] In addition, there is no baffle design in the present application. The cutoff line forming mechanism 23 is integrated with the reflection module 2, and the high and low light spots are formed by the lens module 3. Compared with forming the cutoff line profile by installing a baffle, the present application simplifies the optical parts and is beneficial to reducing the size of the incident surface of the lens module 3, thereby achieving the purpose of lightweighting and reducing the cost of the module.
[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
