[0003]但是,由于近光光学元件1a和远光光学元件2a相互接触或者距离较近,上述两者采用同种材料制成且一般采用较硬的PC或PMMA,两者之间多少会存在缝隙使得近光光形和远光光形的衔接处出现暗区,而且,车灯发生振动时两者相互摩擦会产生一定磨损,更加加剧了两者的磨损程度,甚至磨损至出粉,影响了车灯出射光形的稳定性,降低了车灯寿命,同时,由于两者之间磨损,使近光光学元件1a和远光光学元件2a前端的间距增大,又会使得近光光形和远光光形衔接处的暗区更明显
[0022]In the basic technical solution of this invention, the automotive lamp optical element is configured as a focusing part, a first light-transmitting part, and a second light-transmitting part made of two different materials. The focusing part, the first light-transmitting part, and the second light-transmitting part are integrally molded parts, wherein the focusing part and the second light-transmitting part are silicone molded parts, and the first light-transmitting part is plastic molded parts. This invention creatively divides the automotive lamp optical element into three parts. The focusing part is made of silicone material, which has a higher cost and a higher heat distortion temperature, while the first light-transmitting part is made of plastic material, which has a lower cost and a relatively lower heat distortion temperature. This balances the cost and high-temperature resistance of the automotive lamp optical element, making the focusing part less susceptible to heat deformation and thus ensuring the stability of the emitted light pattern. Moreover, since the second light-transmitting part made of silicone is softer, it is less prone to wear with other optical components. The second light-transmitting part can contact the front end of other optical components in the headlight module, making the light pattern emitted by the automotive lamp optical element more uniformly connected with the light patterns emitted by other optical components, and preventing dark areas. Furthermore, in a preferred embodiment of the present invention, a first interface and a second interface are formed at the contact points between the light-concentrating part and the first light-transmitting part, as well as between the first light-transmitting part and the second light-transmitting part. The two sides of the first interface and the second interface are made of different materials with different refractive indices, which enables the first interface and the second interface to have a secondary light distribution function. Light is deflected from the light-concentrating part and incident on the first light-transmitting part, and then incident on the second light-transmitting part. The direction of light illumination can be changed at the first interface and the second interface to achieve the purpose of adjusting the light shape angle and improving the uniformity of the light shape. Thus, the automotive lamp optical element proposed in this invention can achieve secondary light distribution and improve the degree of freedom of light distribution.

Abstract
Description
Technical Field
[0001] This invention relates to vehicle lighting devices, and more specifically, to a vehicle lamp optical element. Furthermore, this invention also relates to a headlight module including the aforementioned vehicle lamp optical element, a vehicle lamp, and a vehicle. Background Technology
[0002] In the prior art, in order to form the low beam and high beam patterns of a vehicle, the headlight simultaneously includes a low beam optical element 1a and a high beam optical element 2a. Furthermore, referring to... Figure 1 and Figure 2 In order to achieve a good connection between the near beam and the far beam and to avoid the formation of a dark area at the junction of the near beam and the far beam, the front ends of the two optical elements are in contact with each other or are only a small distance apart (generally less than 1 mm).
[0003] However, since the low beam optical element 1a and the high beam optical element 2a are in contact with each other or are close to each other, and both are made of the same material, generally the relatively hard PC or PMMA, there will be some gaps between them, resulting in dark areas at the junction of the low beam and high beam patterns. Moreover, when the headlight vibrates, the two will rub against each other, which will cause some wear, further aggravating the wear of both, and even causing powder to be produced, affecting the stability of the headlight's emitted light pattern and reducing the headlight's lifespan. At the same time, due to the wear between the two, the distance between the front ends of the low beam optical element 1a and the high beam optical element 2a increases, which will make the dark areas at the junction of the low beam and high beam patterns more obvious.
[0004] In addition, refer to Figure 3 and Figure 4 In existing automotive lamp optical components, the focusing cup 3a and the light source 4a are arranged close together. When the light source 4a is turned on, it generates a large amount of heat, which causes the focusing cup 3a to deform or melt due to heat. This affects the shape of the light emitted by the lamp, seriously affects the performance of the lamp, and may even lead to damage to the lamp, posing a great threat to traffic safety.
[0005] To solve the problem of heat and deformation of automotive lamp optical components, the following solutions have been adopted by those skilled in the art: (1) The distance between the condenser cup 3a and the light source 4a is set to a large value, generally at least 0.5 mm, and sometimes even 1 to 2 mm, so that the light source 4a is as far away from the condenser cup 3a as possible. However, setting the distance between the condenser cup 3a and the light source 4a to a large value will result in a loss of the optical efficiency of the automotive lamp; (2) The end of the condenser cup 3a close to the light source 4a is partially cut so that the condenser cup 3a and the light source 4a maintain a certain distance. However, cutting the condenser cup 3a will also reduce the utilization rate of light by the automotive lamp optical components, resulting in a loss of the optical efficiency of the automotive lamp.
[0006] In summary, the light-emitting end of the existing automotive lamp optical components cannot reduce the wear and tear of the lamp while ensuring uniform connection between the low beam and high beam patterns. The light-receiving end also cannot balance cost, optical efficiency, and high-temperature resistance.
[0007] Therefore, it is necessary to design a new type of automotive lamp optical element. Summary of the Invention

[0011] The technical problem to be solved by the fourth aspect of the present invention is to provide a vehicle whose headlights can balance cost, high temperature resistance and wear resistance.
[0012] To solve the above-mentioned technical problems, the present invention provides an automotive lamp optical element, including a light-concentrating part, a first light-transmitting part and a second light-transmitting part arranged sequentially, wherein the light-concentrating part, the first light-transmitting part and the second light-transmitting part are integrally molded parts, the light-concentrating part and the second light-transmitting part are silicone molded parts, and the first light-transmitting part is a plastic molded part.

[0015] More preferably, the second interface has a plurality of forward-protruding and / or backward-recessed curved surfaces.
[0016] Specifically, the upper edge of the second light-transmitting part forms a high beam cutoff line structure to project and form a high beam cutoff line, or the lower edge of the second light-transmitting part forms a low beam cutoff line structure to project and form a low beam cutoff line.
[0017] A second aspect of the present invention also provides a headlight module, including a light source, a low beam optical element, a high beam optical element, and a lens, wherein at least one of the low beam optical element and the high beam optical element is configured as the vehicle lamp optical element described in any one of the first aspect technical solutions.
[0018] Preferably, one of the low-beam optical element and the high-beam optical element is configured as the vehicle lamp optical element, and the other is configured as a vehicle lamp cooperating optical element.
[0019] Alternatively, the vehicle headlight and optical element may include a light-incident section, a light-guide section, and a light-exit section, wherein the light-incident section is a silicone molding part, and the light-guide section and the light-exit section are plastic molding parts; or the light-exit section is a silicone molding part, and the light-incident section and the light-exit section are plastic molding parts; or the vehicle headlight and optical element may be a plastic molding part.

[0022] In the basic technical solution of this invention, the automotive lamp optical element is configured as a focusing part, a first light-transmitting part, and a second light-transmitting part made of two different materials. The focusing part, the first light-transmitting part, and the second light-transmitting part are integrally molded parts, wherein the focusing part and the second light-transmitting part are silicone molded parts, and the first light-transmitting part is plastic molded parts. This invention creatively divides the automotive lamp optical element into three parts. The focusing part is made of silicone material, which has a higher cost and a higher heat distortion temperature, while the first light-transmitting part is made of plastic material, which has a lower cost and a relatively lower heat distortion temperature. This balances the cost and high-temperature resistance of the automotive lamp optical element, making the focusing part less susceptible to heat deformation and thus ensuring the stability of the emitted light pattern. Moreover, since the second light-transmitting part made of silicone is softer, it is less prone to wear with other optical components. The second light-transmitting part can contact the front end of other optical components in the headlight module, making the light pattern emitted by the automotive lamp optical element more uniformly connected with the light patterns emitted by other optical components, and preventing dark areas. Furthermore, in a preferred embodiment of the present invention, a first interface and a second interface are formed at the contact points between the light-concentrating part and the first light-transmitting part, as well as between the first light-transmitting part and the second light-transmitting part. The two sides of the first interface and the second interface are made of different materials with different refractive indices, which enables the first interface and the second interface to have a secondary light distribution function. Light is deflected from the light-concentrating part and incident on the first light-transmitting part, and then incident on the second light-transmitting part. The direction of light illumination can be changed at the first interface and the second interface to achieve the purpose of adjusting the light shape angle and improving the uniformity of the light shape. Thus, the automotive lamp optical element proposed in this invention can achieve secondary light distribution and improve the degree of freedom of light distribution.

[0045] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention, and the scope of protection of the present invention is not limited to the specific embodiments described below.
[0046] It is necessary to understand that, such as Figure 5Based on the vehicle headlight optical element, when it is normally installed in the headlight, along the light emission direction, "front" refers to the end where the second light-transmitting part 13 is located, "rear" refers to the end where the light-concentrating part 11 is located, "up" refers to the upper part along the light emission direction, and "lower" refers to the lower part along the light emission direction. In actual installation, the orientation terms should be interpreted based on the actual installation state and the vehicle headlight optical element itself. The terms are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.
[0047] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. In this invention, "multiple" refers to two or more.
[0048] It should also be noted that, for the purpose of the headlight design and other requirements, at least one inner light distribution mirror can be installed between the headlight optical element and the outer light distribution mirror. The inner light distribution mirror can be a regular plastic part with the same wall thickness, just to present the required shape, or it can be a light distribution plastic part with a light distribution function on the back.
[0049] refer to Figure 5The automotive lamp optical element of the basic embodiment of the present invention includes an integrally formed light-concentrating part 11, a first light-transmitting part 12, and a second light-transmitting part 13. The light-concentrating part 11 and the second light-transmitting part 13 are silicone molding parts, and the first light-transmitting part 12 is a plastic molding part. The light-concentrating part 11 is a light-concentrating cup structure. A concave cavity is formed at the end of the light-concentrating cup structure away from the first light-transmitting part 12. The concave cavity includes a front light-incident surface and a side light-incident surface. The front light-incident surface is a curved surface protruding towards the side away from the first light-transmitting part 12, and the side light-incident surface is a curved surface whose diameter gradually decreases from the end away from the first light-transmitting part 12 to the end closer to the first light-transmitting part 12. The outer contour surface of the light-concentrating cup structure is a curved surface whose diameter gradually increases from the end away from the first light-transmitting part 12 to the end closer to the first light-transmitting part 12. The focusing section 11 refracts a portion of the light emitted by the light source 3 to the first light-transmitting section 12 through the front light-incident surface of the concave cavity. The side light-incident surface of the concave cavity refracts other light emitted by the light source 3, and then reflects the refracted light back to the first light-transmitting section 12 through the outer contour surface. This essentially achieves full utilization of the light beam emitted by the light source 3, thereby improving the utilization rate of the light beam. Of course, the focusing section 11 of the present invention is not limited to the above-described focusing cup structure. The focusing section 11 can also be a rearward convex curved surface structure or other structural forms that can perform a focusing function. The first light-transmitting section 12 is a straight-line solid light conductor extending in the front-back direction. The light emitted by the light source 3 is converged by the focusing section 11 and then directed to the first light-transmitting section 12; or, the first light-transmitting section 12 is a bent solid light conductor, forming an approximately L-shaped light path overall. It is understood that the above are only two preferred structural forms of the first light-transmitting part 12. The structure of the first light-transmitting part 12 and the relative position between the first light-transmitting part 12 and the light-concentrating part 11 can also be flexibly set according to the needs of the headlight design, so that the headlight design is more novel and varied, and meets the user's needs for personalized and technological headlight design.
[0050] In the basic technical solution of this invention, the automotive lamp optical element is divided into a focusing part 11, a first light-transmitting part 12, and a second light-transmitting part 13, both made of two different materials. The focusing part 11 and the second light-transmitting part 13 are silicone molding parts, while the first light-transmitting part 12 is a plastic molding part. For the focusing part 11, since the heat distortion temperature of silicone is greater than that of plastic, the focusing part 11 is less prone to heat deformation, thus ensuring the stability of the emitted light pattern. Furthermore, it eliminates the need to design an excessively large distance between the focusing part 11 and the light source 3 to prevent heat deformation or melting of the focusing part 11, and also eliminates the need for cutting the focusing part 11 or requires only minor cutting. This allows the focusing part 11 to fully collect the light emitted by the light source 3, improving the light utilization rate of the automotive lamp optical element. For the second light-transmitting part 13, since silicone is relatively soft, when the automotive lamp optical element of this invention comes into contact with other optical devices, it can effectively prevent wear and tear on those devices. For example, when the headlight optical element is used to form a low beam pattern, vibration of the headlight causes the second light-transmitting part 13 to rub against the front end of the high beam optical element in the headlight module. Since the second light-transmitting part 13 is relatively soft, neither the second light-transmitting part 13 nor the high beam optical element is prone to wear, resulting in a more reliable emitted light pattern and effectively improving the vibration reliability of the headlight. Alternatively, multiple headlight optical elements of the present invention can be used in the headlight module. The second light-transmitting parts 13 of the multiple headlight optical elements rub against each other. Since the second light-transmitting parts 13 are relatively soft, each second light-transmitting part 13 will not experience severe wear. Because the second light-transmitting part 13 and other optical components are not prone to wear, the second light-transmitting part 13 can contact or be at a small distance from the front end of other optical components in the headlight module. This further makes the light pattern emitted by the headlight optical element and the light patterns emitted by other optical components more uniformly connected, ensuring the stability of the emitted light pattern and extending the headlight's lifespan. It is understandable that using silicone material in at least one of the light-concentrating part 11 and the second light-transmitting part 13 of the automotive lamp optical element can improve the heat resistance and / or wear resistance of the automotive lamp optical element. In addition, silicone has a high heat distortion temperature but is expensive. Therefore, silicone material is used in the light-concentrating part 11 and the second light-transmitting part 13, which have a smaller volume. Ordinary plastics have a low heat distortion temperature but are inexpensive. Therefore, plastics such as polycarbonate (PC) and polymethyl methacrylate (PMMA) are used in the first light-transmitting part 12, which has a larger volume and is farther away from the light source. This balances the cost, heat resistance and wear resistance of the automotive lamp optical element.
[0051] As a specific structural form, a first interface 14 is formed between the light-concentrating part 11 and the first light-transmitting part 12, and a second interface 15 is formed between the first light-transmitting part 12 and the second light-transmitting part 13. Regarding the first interface 14, depending on the light distribution requirements, it can optionally be a forward-convex curved surface, a flat surface, or a backward-concave curved surface. Regarding the second interface 15, the first light-transmitting part 12 and the second light-transmitting part 13 can have various connection forms, as long as the part in contact with other optical devices is made of silicone. As a specific structural form, refer to... Figure 5 A second interface 15 is formed between the second light-transmitting portion 13 and the first light-transmitting portion 12. The second interface 15 is a forward-protruding curved surface, a plane, or a rearward-recessed curved surface. Alternatively, as another specific structural form, refer to... Figures 6 to 9 The second interface 15 is a bent surface, so that the first light-transmitting part 12 covers the second light-transmitting part 13, exposing only the front end surface and the contact surface for contacting other optical devices of the second light-transmitting part 13. This combination can further increase the area of the second interface 15 between the second light-transmitting part 13 and the first light-transmitting part 12, increase the bonding force between the two, and reduce the material consumption of the second light-transmitting part 13. Preferably, in order to adapt to the size of the existing vehicle headlights and save material of the second light-transmitting part 13, the thickness of the second light-transmitting part 13 is less than 20 mm. More preferably, the thickness of the second light-transmitting part 13 is less than 10 mm.
[0052] The automotive lighting element can be integrally molded using insert injection molding. First, the focusing part 11 and the second light-transmitting part 13 are produced, and then the focusing part 11 and the second light-transmitting part 13 are integrally molded with the first light-transmitting part 12 as inserts; alternatively, it can be directly integrally molded using two-color injection molding. The first interface 14 and the second interface 15 are made of different materials with different refractive indices, giving them a secondary light distribution function. Light is deflected from the focusing part 11 and incident on the first light-transmitting part 12, and then deflected from the first light-transmitting part 12 and incident on the second light-transmitting part 13. The direction of light illumination can be changed at the first interface 14 and the second interface 15, achieving the purpose of adjusting the light shape angle and improving the uniformity of the light shape. This allows the automotive lighting element proposed in this invention to achieve secondary light distribution, increasing the degree of freedom in light distribution. Furthermore, the automotive lighting element has a simple structure, meets the process requirements of integral molding or two-color injection molding, and is suitable for mass production.
[0053] To enhance headlight brightness and meet users' needs for personalized, technologically advanced headlight designs, the rear end of the first light-transmitting section 12 has multiple light-concentrating sections 11. These light-concentrating sections 11 can be integrated as a single unit, or they can be separated. (Reference) Figure 5Multiple first interfaces 14 are interconnected to form a smooth curved surface or plane, simplifying the structure of the light-concentrating part 11 and the first light-transmitting part 12, improving production efficiency and reducing production costs; or, multiple first interfaces 14 are staggered with a drop, so that the shape and tilt angle of each first interface 14 can be adjusted to make the light distribution more flexible and enable better secondary light distribution.
[0054] More preferably, refer to Figure 10 and Figure 11 The second interface 15 has multiple forward-protruding or backward-recessed curved surfaces. Specifically, the curved surfaces can be single-row multi-column, multi-row single-column, or multi-row multi-column. These curved surfaces can further enhance the secondary light distribution effect, making the light pattern of the vehicle lamp's optical elements more uniform.
[0055] Optionally, the upper edge of the second light-transmitting section 13 may form a high-beam cutoff line structure to project a high-beam cutoff line, wherein the high-beam cutoff line structure is a smooth curve or a curve with steps; or the lower edge of the second light-transmitting section 13 may form a low-beam cutoff line structure to project a low-beam cutoff line, wherein the low-beam cutoff line structure is a curve with steps. The front end face of the second light-transmitting section 13 may be formed as a smooth curved surface that curves forward on both sides, making the cutoff line of the emitted light pattern clearer and sharper.
[0056] The preferred embodiment of the automotive lamp optical element of the present invention, with reference to Figure 5 The first light-transmitting part 12 has multiple light-concentrating parts 11 formed at its rear end, and a second light-transmitting part 12 is formed at its front end. The light-concentrating parts 11 and the second light-transmitting parts 13 are silicone molded parts, while the first light-transmitting part 12 is a plastic molded part. A first interface 14 is formed between the light-concentrating parts 11 and the first light-transmitting parts 12, and a second interface 15 is formed between the first light-transmitting parts 12 and the second light-transmitting parts 13. The second interface 15 is a plane. Specifically, multiple first interfaces 14 are connected to form a plane, and multiple curved surfaces that bulge forward or recline backward are formed on the second interface 15. The lower edge of the second light-transmitting part 13 forms a low beam cutoff line structure. When this automotive lamp optical element is applied in a headlight module, the light-concentrating part 11 can be closer to the light source 3 to achieve a higher light utilization rate; the second light-transmitting part 13 will not experience severe wear when it rubs against other optical components due to vehicle lamp vibration.
[0057] The headlight module of the present invention, referenced Figures 12 to 14The system includes a light source 3, a low-beam optical element, a high-beam optical element, and a lens 2. At least one of the low-beam and high-beam optical elements is configured as a vehicle lamp optical element according to any one of the first aspects of the technical solution. The light source 3 is located behind the focusing part 11, and the light source 3 can be an LED chip or an OLED chip, etc. The low-beam and high-beam optical elements are arranged vertically, and the lens 2 is located in front of the low-beam and high-beam optical elements. As a structural form, both the low-beam and high-beam optical elements are configured as vehicle lamp optical elements according to any one of the first aspects of the technical solution: the two vehicle lamp optical elements are arranged vertically and each has a second light-transmitting part 13, which are in contact with each other. The light-incident parts of the low-beam and high-beam optical elements are both heat-resistant, and there is no wear between the light-exiting parts.
[0058] Preferably, one of the low beam optical element and the high beam optical element is configured as the vehicle lamp optical element, and the other is configured as the vehicle lamp cooperating optical element 4. The vehicle lamp optical element is disposed above or below the vehicle lamp cooperating optical element 4, and when subjected to vibration, the second light-transmitting part 13 of the vehicle lamp optical element can generate friction with the light-emitting end of the vehicle lamp cooperating optical element 4.
[0059] The headlight-mounted optical element 4 includes a light-incident section 41, a light-guide section, and a light-exit section. This optical element 4 can adopt various structural forms. For example, only the light-incident section 41 of the headlight-mounted optical element 4 may be a silicone-molded part, while the light-guide and light-exit sections are both plastic-molded parts. The light-exit section of this optical element 4 contacts the second light-transmitting section 13 of the aforementioned headlight optical element. Alternatively, the light-exit section of the headlight-mounted optical element 4 may be a silicone-molded part, while the light-incident and light-guide sections are plastic-molded parts. The light-exit section of this optical element 4 contacts the second light-transmitting section 13 of the aforementioned headlight optical element. Or, the entire headlight-mounted optical element 4 may be a plastic-molded part. In other words, having at least one of the light-incident and light-exit sections of the low-beam and high-beam optical elements as a silicone-molded part can improve the problem of the light-incident section being susceptible to high temperatures and / or the light-exit section being prone to wear in the headlight module.

The vehicle lamp of the present invention may include the headlight module described in the above embodiments, and therefore possesses at least all the beneficial effects brought about by the technical solutions of the embodiments of the headlight module described above.
[0061] The vehicle of the present invention includes the headlights in the third aspect of the technical solution, which may include the headlights in the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above-described headlight embodiments.
