Description

Technical Field

[0001] The utility model relates to the technical field of automobile lighting, and in particular to an integrated reflector, a headlight optical system, a headlight assembly and a vehicle. Background Art

[0002] The existing headlight optical systems are generally divided into reflective and projective types. Among them, the reflective optical system is widely used in low-end models due to its low manufacturing cost. The reflective optical system can realize functions such as low beam, high beam, matrix high beam and corner light.

[0003] Traditional reflective optical systems want to achieve high and low beam functions mainly through the following two forms: one is to use multiple split reflectors, including low beam reflectors and high beam reflectors. The multiple reflectors are independent of each other and dimmed separately. In this case, the design of each light type can be optimized, and the performance is better. At the same time, it can also ensure that the size of a single reflector is not too large, which is convenient for controlling injection molding deformation. However, in terms of manufacturing cost, the use of multiple separate reflectors will increase the manufacturing cost to a certain extent; the other is to use an integrated reflector, that is, the low beam and high beam functions are integrated into one reflector. In this case, there is a disadvantage that the lateral size of the reflector is too large, there are too many restrictions on the layout requirements of the shape, and it is also not conducive to the control of injection molding deformation.

[0036] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Please refer to Figures 1 to 11 The embodiment of the present application provides a headlight optical system 100, including a light source 10 and an integrated reflector 20. The light emitted by the light source 10 is emitted toward the integrated reflector 20, and is reflected to the target projection area by the integrated reflector 20. The headlight optical system 100 can form a high beam light shape and a low beam light shape in one reflector (i.e., the integrated reflector 20), so that the headlight optical system 100 can achieve high and low beam functions. Since the headlight optical system 100 has only one reflective component (i.e., the integrated reflector 20), and the headlight optical system 100 does not have a complex dimming alignment structure, the headlight optical system 100 has the advantage of a simple structure, which can greatly increase the diversity of spatial layout, and can also reduce the manufacturing cost of the headlight optical system 100.

[0038] Specifically, Figure 5 As shown, the light source 10 includes a low beam light source 11, a first high beam light source 12 and a second high beam light source 13. Figure 1 and Figure 2As shown, the integrated reflector 20 includes a low beam reflection cavity 21, a first high beam reflection cavity 22 and a second high beam reflection cavity 23, the low beam light source 11 is arranged correspondingly to the low beam reflection cavity 21 of the integrated reflector 20, the first high beam light source 12 is arranged correspondingly to the first high beam reflection cavity 22 of the integrated reflector 20, and the second high beam light source 13 is arranged correspondingly to the second high beam reflection cavity 23 of the integrated reflector 20. Among them, the light source 10 can be an LED light source 10.

[0039] It should be noted that the light source 10 is a plurality of dispersed light sources 10 corresponding to the plurality of (including low beam and high beam) reflection cavities of the integrated reflector 20 , respectively. Therefore, the actual number of the light sources 10 corresponds to the actual number of the reflection cavities of the integrated reflector 20 . Among them, since the low beam light source 11 is correspondingly arranged with the low beam reflection cavity 21 of the integrated reflector 20, the light emitted by the low beam light source 11 can be emitted toward the low beam reflection cavity 21 of the integrated reflector 20, and reflected to the target projection area through the low beam reflection cavity 21 of the integrated reflector 20; similarly, since the first high beam light source 12 is correspondingly arranged with the first high beam reflection cavity 22 of the integrated reflector 20, the light emitted by the first high beam light source 12 can be emitted toward the first high beam reflection cavity 22 of the integrated reflector 20, and reflected to the target projection area through the first high beam reflection cavity 22 of the integrated reflector 20; similarly, since the second high beam light source 13 is correspondingly arranged with the second high beam reflection cavity 23 of the integrated reflector 20, the light emitted by the second high beam light source 13 can be emitted toward the second high beam reflection cavity 23 of the integrated reflector 20, and reflected to the target projection area through the second high beam reflection cavity 23 of the integrated reflector 20.

[0040] Regarding the actual number of the low beam light sources 11, the first high beam light sources 12 and the second high beam light sources 13, technical personnel in this field should be able to make reasonable selections and designs based on actual conditions. It is only necessary to make the actual number of the low beam light sources 11 correspond to the actual number of the low beam reflection cavities 21, the actual number of the first high beam light sources 12 correspond to the actual number of the first high beam reflection cavities 22, and the actual number of the second high beam light sources 13 correspond to the actual number of the second high beam reflection cavities 23. No specific restrictions are made here.

[0041] Specifically, Figures 1 to 4 As shown, the integrated reflector 20 includes a low beam reflection cavity 21, a first high beam reflection cavity 22 and a second high beam reflection cavity 23. The first high beam reflection cavity 22 is arranged at one side of the low beam reflection cavity 21 in the horizontal direction, the second high beam reflection cavity 23 is arranged at a side of the low beam reflection cavity 21 away from the light source 10 in the vertical direction, and the second high beam reflection cavity 23 is arranged in front of or behind the low beam reflection cavity 21 in the depth direction. The integrated reflector 20 can solve the problems of large lateral dimensions of the integrated reflector 20 and high manufacturing costs of the split reflector.

[0042] It should be noted that if Figure 6 and Figure 8 As shown, when the low beam reflection area of ​​the integrated reflector 20 is arranged, the integrated reflector 20 includes at least one low beam reflection cavity 21, so that the low beam light shape is formed through the low beam reflection cavity 21, so that the vehicle light optical system 100 can realize the low beam function; Figure 7 , Fig. 9 and Fig.10 As shown, when arranging the high beam reflection area of ​​the integrated reflector 20, the high beam light shape is divided into two parts: a high beam widening and a high beam bright spot. Therefore, the integrated reflector 20 includes at least one first high beam reflection cavity 22 and at least one second high beam reflection cavity 23. The first high beam reflection cavity 22 is arranged on one side of the low beam reflection cavity 21 in the horizontal direction (the left side or the right side, the left side is taken as an example for explanation in the accompanying drawings) to form the high beam widening part of the high beam light shape through the first high beam reflection cavity 22, and the second high beam reflection cavity 23 is arranged on the side of the low beam reflection cavity 21 in the vertical direction away from the light source 10 (the light source 10 is on the upper side and the second high beam reflection cavity 23 is on the lower side in the illustrated orientation) to form the high beam bright spot part of the high beam light shape through the second high beam reflection cavity 23, so that the vehicle light optical system 100 can realize the high beam function.

[0043] To sum up, compared with the split reflector in the prior art, since the headlight optical system 100 has one and only one reflective component (i.e., the integrated reflector 20), the headlight optical system 100 has the advantage of simple structure, which can reduce the manufacturing cost of the headlight optical system 100; compared with the integrated reflector in the prior art, since the integrated reflector 20 arranges part of the high beam reflection area (i.e., the second high beam reflection cavity 23) on one side of the low beam reflection area (i.e., the low beam reflection cavity 21) along the vertical direction, the overall lateral size of the integrated reflector 20 can be reduced.

[0044] Alternatively, if Figure 1 and Figure 2 As shown, in this embodiment, the lower boundary of the first high beam reflection cavity 22 is flush with the lower boundary of the second high beam reflection cavity 23 to improve the integrity and consistency of the appearance of the integrated reflector 20. Of course, in other embodiments, the lower boundary of the first high beam reflection cavity 22 is staggered with the lower boundary of the second high beam reflection cavity 23, and those skilled in the art should be able to make reasonable selections and designs according to actual conditions.

[0045] like Figure 5As shown, when the second high-beam reflection cavity 23 is arranged at the lower side of the low-beam reflection cavity 21 in the vertical direction, the high-beam reflection surface of the second high-beam reflection cavity 23 is prone to generate stray light. In order to solve the above problem, in this embodiment, the distance between the focus of the second high-beam reflection cavity 23 (i.e., the layout position of the second high-beam light source 13) and the focus of the low-beam reflection cavity 21 (i.e., the layout position of the low-beam light source 11) in the depth direction is greater than or equal to 10mm. For example, the distance can be 10mm, 11mm, 12mm or 15mm, etc. Those skilled in the art should be able to make reasonable selections and designs according to actual conditions, and no specific restrictions are made here.

[0046] like Figure 6 As shown, in this way, the high beam reflection surface of the second high beam reflection cavity 23 can effectively avoid the reflection of the low beam light, and can ensure that there is no stray light formed by the high beam reflection area (i.e., the second high beam reflection cavity 23) on the upper side of the low beam cut-off line, thereby solving the problem that when the second high beam reflection cavity 23 is arranged on the lower side of the low beam reflection cavity 21 in the vertical direction, the high beam reflection surface of the second high beam reflection cavity 23 is prone to generate stray light.

[0047] Alternatively, if Figure 1 and Figure 3 As shown, the low beam reflection cavity 21 includes at least one, and when the low beam reflection cavity 21 includes multiple low beam reflection cavities, the multiple low beam reflection cavities 21 are sequentially arranged along the depth direction. Figure 3 and Figure 5 As shown, correspondingly, when there are multiple low-beam reflection cavities 21, there are also multiple low-beam light sources 11, and the multiple low-beam light sources 11 correspond one-to-one to the multiple low-beam reflection cavities 21. In addition, the first high-beam light source 12 corresponds to the first high-beam reflection cavity 22, and the second high-beam light source 13 corresponds to the second high-beam reflection cavity 23, respectively.

[0048] Alternatively, if Figure 5 As shown, the headlight optical system 100 further includes a circuit board 30 , on which the low beam light source 11 , the first high beam light source 12 and the second high beam light source 13 are all arranged, so that the headlight optical system 100 can be controlled by the circuit board 30 for both short and long distance lighting.

[0049] Alternatively, if Figure 2 As shown, the vehicle light optical system 100 further includes a heat sink 40, which is disposed on a side of the light source 10 away from the integrated reflector 20. The heat sink 40 may be an integral forged metal, and is used to effectively dissipate heat for the light source 10.

[0050] The embodiment of the present application further provides a vehicle lamp assembly, including the above vehicle lamp optical system 100. Since the structure and beneficial effects of the vehicle lamp optical system 100 have been described in detail in the above embodiments, they will not be described again here.

[0051] The embodiment of the present application further provides a vehicle, comprising the above-mentioned vehicle lamp assembly. Since the structure and beneficial effects of the vehicle lamp assembly have been described in detail in the above-mentioned embodiment, they will not be described in detail here.

[0052] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0053] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
