Description

Technical Field

[0001] The utility model relates to the technical field of automobile lighting lamps, in particular to a high and low beam module with a cut-off line distance adjustable function. Background Art

[0002] As automotive lighting systems place increasingly higher demands on headlight optics, lens manufacturing capabilities must be consistent with previous optical simulations. This places a more stringent test on changes in low beam focal length caused by lens component deviations and assembly errors. In order to adapt to this trend, traditional lens modules have been unable to meet demand, which poses new challenges to breaking through the design of traditional lens modules. It is urgent to reduce changes in module low beam focal length.

[0003] The cut-off baffle position of a conventional lens module is generally fixed and cannot be adjusted. Due to the deviation of the lens size, the focal length of the low beam changes, affecting the gradient, chromaticity of the low beam, and the dark gap when the low beam and the far beam are lit at the same time. In order to improve these problems, the purpose of the present invention is to provide a method for improving the focal length of the low beam, thereby improving the gradient, chromaticity of the low beam, and the dark gap when the high beam and the far beam are lit at the same time, thereby improving the stability of the optical system. Utility Model Content

[0004] The utility model aims to provide a high and low beam module with a cut-off line distance adjustable function, so as to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The high and low beam module with the function of adjustable cutoff line distance comprises a lens, a decorative ring, a small iron, a cutoff line baffle, a concentrator, a PCB board, a radiator and a bracket, the decorative ring is fixedly mounted on the bracket, the lens is fixedly mounted on the end of the decorative ring away from the bracket, the small iron is fixedly mounted inside the decorative ring perpendicular to the bracket, through holes are provided on both sides of the decorative ring, the cutoff line baffle is fixedly mounted at the through holes on both sides of the decorative ring, the radiator is fixedly mounted on the other end of the bracket, the PCB board is fixedly mounted on the radiator, the concentrator is mounted on one side of the PCB board and fixed to the radiator together, the PCB board is electrically connected to an external controller, and a distance adjustable mounting structure is provided on the cutoff line baffle, and the position of the cutoff line baffle is adjusted by the distance adjustable mounting structure.

[0007] The lens is used to collimate the light inside the module and form an image to further illuminate the car lights, allowing the light to shine farther and brighter. The decorative ring is used as the retaining frame of the module assembly. The small iron is used to prevent sunlight from focusing and burning the internal parts of the module. The cutoff baffle is used to improve the focal length of the low beam, ensuring the gradient and chromaticity of the low beam, and the connection between the high and low beams when they are lit at the same time. The concentrator is used for the low beam light guide and the high beam light guide. The PCB board is used to control the start and stop of the light. The radiator is used for the heat dissipation of the module. The bracket is used to fix the decorative ring and the radiator.

[0008] When the controller transmits the electrical signal to the PCB board, the PCB board transmits the signal to the light-emitting element to emit light, the light enters the concentrator, is reflected and refracted under the action of the concentrator, and finally passes through the lens to the outside world.

[0009] Furthermore, the lens is fixedly mounted on the decorative ring by means of buckles.

[0010] In order to improve installation efficiency, reduce installation costs and improve installation stability, the lens is fixed on the decorative ring by means of a snap buckle.

[0011] Furthermore, the lens micro pattern is in the shape of a regular octagon.

[0012] The purpose of shaping the lens micro-pattern into a regular octagon is to make the light more evenly distributed inside the lens, avoiding the appearance of light spots or dark areas, thereby improving the lighting effect. It also helps to adjust the refraction and reflection path of light so that the light can more accurately illuminate the required area, improving the clarity of vision during night driving.

[0013] Furthermore, the cut-off line baffle is provided with a folded edge boss structure parallel to the bracket and with a rounded transition, the folded edge boss structure on the cut-off line baffle has a height of 1.5 mm and a width of 1 mm, and a square groove is provided near the inflection point of the cut-off line baffle.

[0014] In order to improve the low beam point on SAE, prevent glare and improve the stability of the optical system, a folded edge boss structure with a height of 1.5mm and a width of 1mm is provided on the cut-off line baffle.

[0015] Furthermore, three waist-shaped columns are provided at the through hole of the decorative ring, three waist-shaped holes are provided on the surface of the cut-off line baffle, and the waist-shaped column in the middle of the decorative ring passes through the waist-shaped hole in the middle of the cut-off line baffle.

[0016] By moving the position of the cut-off line baffle and changing the relative position of the waist-shaped hole and the waist-shaped column, the equipment can find a suitable position and then fix it. This change can realize the forward and backward movement of the cut-off line baffle, thereby improving the low beam focal length problem of mass-produced parts and ensuring the connection between the low beam gradient, chromaticity, and simultaneous lighting of high and low beams.

[0017] Furthermore, the light incident surface of the concentrator has 4 discontinuous curved surfaces, and the light exit surface of the concentrator has 15 discontinuous curved surfaces.

[0018] The light incident surface is designed with 4 intermittent curved surfaces, so the concentrator can more effectively adjust and control the propagation path of light. This design allows the light to be distributed more evenly, reducing the appearance of light spots and dark areas, thereby improving the lighting effect and ensuring that the road surface or other targets are adequately illuminated. At the same time, the intermittent curved surface design helps to reduce the scattering and reflection of light, allowing the light to be more concentrated and focused, and also helps to increase the surface area of ​​the concentrator, thereby improving the heat dissipation performance and helping to reduce the heat generated by the concentrator during operation, extending its service life; the light exit surface is designed with 15 intermittent curved surfaces, so that the concentrator can better control the refraction and reflection path of light, thereby achieving a more uniform and precise light distribution and reducing the scattering of light, which helps to improve the clarity of vision during night driving and enhance driving safety.

[0019] Furthermore, the heat sink is cold forged, and the heat sink fins on the heat sink are S-shaped.

[0020] The cold forging process can produce a radiator with excellent heat dissipation performance. The heat sink has a compact structure and a large heat dissipation area, which can effectively dissipate heat and ensure that the equipment maintains a stable temperature during long-term operation. At the same time, the S-shaped heat sink design can increase the surface area of ​​the heat sink, thereby providing more heat dissipation area, so that heat can be dissipated into the air more quickly, and at the same time can guide the air flow, so that the air passes through the heat sink more smoothly, enhancing the heat dissipation effect. At the same time, it can also effectively prevent the wind flow from generating turbulence or eddy currents inside the radiator, further improving the heat dissipation efficiency.

[0021] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the utility model improves the low beam point on the SAE by providing a folded edge boss structure on the cut-off line baffle, thereby preventing glare and improving the stability of the optical system; the cut-off line baffle can be moved forward and backward, thereby improving the low beam focal length problem of mass-produced parts, and ensuring the low beam gradient, chromaticity, and simultaneous lighting and connection of high and low beams; the light incident surface of the concentrator has 4 intermittent curved surfaces, and the light exit surface of the concentrator has 15 intermittent curved surfaces, so that the light can be distributed more evenly, reducing the occurrence of light spots and dark areas, thereby improving the lighting effect and ensuring that the road surface or other targets are fully illuminated; at the same time, the intermittent curved surface design helps to reduce the scattering and reflection of light, so that the light can be more concentrated and focused, and also helps to increase the surface area of ​​the concentrator, thereby improving the heat dissipation performance.

[0034] The lens 1 is used to collimate the light inside the module and form an image to further illuminate the car lights, allowing the light to shine farther and brighter. The decorative ring 2 is used as a retaining frame for the module components. The small iron 3 is used to prevent sunlight from focusing and burning the internal parts of the module.

The condenser 5 is used for the low beam light guide and the high beam light guide. The PCB board 6 is used to control the start and stop of the light. The radiator 7 is used for heat dissipation of the module. The bracket 8 is used for the fixed installation of the decorative ring and the radiator.

[0035] When the controller transmits the electrical signal to the PCB board 6, the PCB board 6 transmits the signal to the light-emitting element to emit light, and the light enters the concentrator 5, is reflected and refracted under the action of the concentrator, and finally passes through the lens 1 to the outside.

[0036] like Figure 1 As shown, the lens 1 is fixedly mounted on the decorative ring 2 by means of buckles.

[0037] In order to improve installation efficiency, reduce installation cost and improve installation stability, the lens 1 is fixedly installed on the decorative ring 2 by means of a buckle.

[0038] like Figure 1 As shown, the shape of the microscopic pattern of lens 1 is a regular octagon.

[0039] The purpose of shaping the lens 1 microscopic pattern into a regular octagon is to make the light more evenly distributed inside the lens, avoiding the appearance of light spots or dark areas, thereby improving the lighting effect. At the same time, it helps to adjust the refraction and reflection path of the light so that the light can be more accurately irradiated to the required area, thereby improving the clarity of vision during night driving.

[0040] like Figure 5As shown, the cut-off line baffle plate 4 is provided with a folded edge boss structure parallel to the bracket and with a rounded transition. The height of the folded edge boss structure on the cut-off line baffle plate 4 is 1.5 mm and the width is 1 mm. A square groove is provided near the inflection point of the cut-off line baffle plate 4.

[0041] In order to improve the low beam point on SAE, prevent glare and improve the stability of the optical system, a folded edge boss structure with a height of 1.5 mm and a width of 1 mm is provided on the cut-off line baffle 4 .

[0045] The light incident surface is designed with four intermittent curved surfaces, so that the concentrator 5 can more effectively adjust and control the propagation path of light. This design allows the light to be distributed more evenly, reduces the appearance of light spots and dark areas, thereby improving the lighting effect and ensuring that the road surface or other targets are adequately illuminated. At the same time, the intermittent curved surface design helps to reduce the scattering and reflection of light, allowing the light to be more concentrated and focused, and also helps to increase the surface area of ​​the concentrator, thereby improving the heat dissipation performance and helping to reduce the heat generated by the concentrator during operation, thereby extending its service life; the light exit surface is designed with 15 intermittent curved surfaces, so that the concentrator 5 can better control the refraction and reflection path of light, thereby achieving more uniform and precise light distribution and reducing light scattering, which helps to improve the clarity of vision during night driving and enhance driving safety.

[0046] like Figure 1 As shown, the heat sink 7 is a cold forging type, and the heat sink fins on the heat sink 7 are S-shaped.

[0047] The cold forging process can produce a heat sink 7 with excellent heat dissipation performance. The heat sink has a compact structure and a large heat dissipation area, which can effectively dissipate heat and ensure that the device maintains a stable temperature during long-term operation. At the same time, the S-shaped heat sink design can increase the surface area of ​​the heat sink, thereby providing more heat dissipation area, so that heat can be dissipated into the air more quickly, and at the same time, it can guide the air flow, so that the air passes through the heat sink more smoothly, and enhance the heat dissipation effect. At the same time, it can also effectively prevent the wind flow from generating turbulence or eddy currents inside the heat sink 7, further improving the heat dissipation efficiency.

[0048] The working principle of this utility model:

[0049] When the controller transmits the electrical signal to the PCB board 6, the PCB board 6 transmits the signal to the light-emitting element to emit light, and the light enters the concentrator 5, is reflected and refracted under the action of the concentrator, and finally passes through the lens 1 to the outside world; by moving the position of the cut-off baffle 4, the relative position of the waist-shaped hole and the waist-shaped column is changed, so that the device finds a suitable position and then fixes it, and this change is used to realize the forward and backward movement of the cut-off baffle 4, thereby improving the low beam focal length problem of mass-produced parts, ensuring the low beam gradient, chromaticity, and the problem of simultaneous lighting of high and low beams; in order to improve the low beam point on SAE, prevent glare and improve the stability of the optical system, a folded edge boss structure is provided on the cut-off baffle 4; the design of the concentrator light entrance surface having 4 intermittent curved surfaces and the concentrator light exit surface having 15 intermittent curved surfaces enables the concentrator 5 to better control the refraction and reflection path of the light, thereby achieving a more uniform and accurate light distribution and reducing the scattering of light, and at the same time, the light can be more evenly distributed, reducing the appearance of light spots and dark areas, thereby improving the lighting effect.
