Abstract
Description
Technical Field
[0001] The present application relates to the automotive field, and in particular to a vehicle position lamp and a vehicle thereof. Background Art
[0002] With the development of the new energy vehicle industry, in order to meet people's pursuit of electric technology in new energy vehicles and enhance brand recognition, position lights of various shapes are increasingly used on the exterior of vehicles. Existing vehicle position lights usually use transparent plastic materials that can transmit light as lampshades to achieve the luminous effect of position lights. However, under weather conditions with large temperature differences between day and night or high humidity, water mist will appear on the inner surface of the lampshade, and in severe cases, water droplets will condense. These water mist or water droplets are visible on the outside of the vehicle, thus affecting the sensory quality.
[0003] To solve this problem, there are some anti-fog measures for position lights in the current industry, but they cannot be completely avoided:
[0004] Add a desiccant bag inside the position lamp to absorb moisture from the air inside the lamp cavity. Due to the limited use of desiccant bags and their water absorption saturation rate, this method can only meet the effectiveness of a new car within a short period of time. Generally, the effective period of use is less than one year, and in humid coastal areas, the effective period of use is even shorter;
[0005] Increase the power of the light-emitting unit and remove the water mist by the heat of the light source in a short period of time after the light is turned on; this method cannot eliminate the fogging during the light-off period and cannot completely solve the problem. Summary of the invention
[0006] The present application provides a vehicle position lamp and a vehicle thereof, which can solve the problem that the anti-fog means of the position lamp in the related art is not effective and the position lamp fogging can be visually seen outside the position lamp.

DETAILED DESCRIPTION
[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0024] The embodiment of the present application provides a vehicle position lamp and a vehicle thereof, which can solve the problem in the related art that the anti-fog means of the position lamp is not effective and the fogging of the position lamp can be visually seen outside the position lamp.
[0025] The traditional automobile position light assembly is mainly composed of a position light transparent lampshade, an internal decorative panel, a light-emitting unit, a PCB board, and a position light rear shell. The position light transparent lampshade and the position light rear shell form a complete lamp cavity, which is filled with air. A number of air holes are generally opened at the rear of the rear shell. The air holes can prevent water from entering the lamp cavity, but allow air and water vapor exchange. In this structure, when the external temperature changes, the air inside the lamp cavity (there is moisture in the air) will form water mist or water droplets on the inner surface of the lampshade and the surface of the internal components of the decorative panel lamp.
[0026] To solve this problem, there are some anti-fog measures for position lights in the current industry, but they cannot be completely avoided:
[0027] One of the anti-fog methods is to add a desiccant bag inside the position lamp to absorb moisture from the air inside the lamp cavity. However, due to the limited use of desiccant bags and their water absorption saturation rate, this method can only meet the effectiveness of a new car within a short period of time, generally less than one year, and even shorter in humid coastal areas;
[0028] The second anti-fog method is to increase the power of the light-emitting unit and remove the water mist by the heat of the light source in a short period of time after the light is turned on; this method cannot eliminate the fogging during the light-off period and cannot completely solve the problem.
[0029] In view of the problem that the anti-fog measures for the position lamp are not effective and the fogging of the position lamp can be visually seen from the outside of the position lamp, in the first aspect, an embodiment of the present application provides a vehicle position lamp, which includes: a front shell, a rear shell 6, a sealing plate 3 and a light-emitting unit 5, wherein the front shell is provided with a light-emitting characteristic surface 10, and the light-emitting characteristic surface 10 is a translucent surface; the rear shell 6 is connected to the front shell, and a lamp cavity is formed between the rear shell and the front shell; the sealing plate 3 is arranged inside the lamp cavity, and divides the lamp cavity into a sealed front cavity 7 composed of the front shell and the sealing plate 3, and a semi-sealed rear cavity 8 composed of the rear shell 6 and the sealing plate 3, and the distance between the sealing plate 3 and the light-emitting characteristic surface 10 is greater than the minimum imaging distance L of the sealing plate relative to the light-emitting characteristic surface (see Figure 2As shown); the light emitting unit 5 is arranged inside the rear cavity 8.
[0030] In the present application, the lamp cavity structure of the position lamp is changed, and the lamp cavity is divided into a front cavity 7 and a rear cavity 8 by a sealing plate 3, and the light-emitting unit 5 is arranged inside the rear cavity 8, so that the fogging surface of the position lamp is transferred from the inner surface of the lampshade of the traditional structure to the back of the sealing plate 3 and the rear cavity 8, and the distance between the sealing plate 3 and the light-emitting characteristic surface 10 is set to be greater than the set minimum imaging distance, and the light-emitting characteristic surface 10 is a translucent surface. When the position lamp is not lit, the internal structure of the lamp cavity behind the light-emitting characteristic surface 10 is invisible. When the position lamp is lit, the light is irradiated to the outside of the front shell through the light-emitting characteristic surface 10, and the position lamp is visible from the outside. In the light-irradiated area inside the lamp body, the internal structure close to the light-emitting characteristic surface 10 is visible, and the internal structure far away from the light-emitting characteristic surface 10 is not visible. Therefore, even if the inside of the rear cavity 8 is fogged, since it is far away from the light-emitting characteristic surface 10, the fogging phenomenon of the position lamp will not be visually observed outside the position lamp.
[0031] Among them, the minimum imaging distance is verified in the test. The minimum imaging distance of the present application refers to the distance at which the human eye can just not see the internal structure of the lamp cavity when viewing the interior of the lamp cavity through the luminous characteristic surface 10, that is, the critical distance at which the internal structure close to the luminous characteristic surface 10 is visible and the internal structure far from the luminous characteristic surface 10 is invisible. The minimum imaging distance of the sealing plate 3 relative to the luminous characteristic surface 10 is different when the luminous characteristic surface 10 has different colors, different transparencies, and different processes. The lower the transparency of the luminous characteristic surface 10, the smaller the minimum imaging distance.
[0032] It should be noted that the top, bottom and left and right sides of the sealing plate 3 are connected to the front shell, so that the front cavity 7 formed between the front end of the sealing plate 3 and the front shell is a sealed cavity; in the present application, since an air hole 60 is provided on the rear shell 6, the rear cavity 8 formed between the rear end of the sealing plate 3 and the rear shell 6 is a semi-sealed cavity. Furthermore, in order to prevent water from entering the lamp cavity, but to allow air and water vapor exchange, a breathable membrane is provided in the air hole 60.
[0033] The overall structure of the vehicle position lamp is shown in Figure 1 As shown, the luminous characteristic surface 10 on the front shell occupies part of the front shell area, and the rest of the front shell area is a non-luminous characteristic surface. The luminous characteristic surface 10 is the area where the light can penetrate the front shell to the outside of the position lamp when the light-emitting unit 5 emits light, so that the light is visible outside.
[0034] In this embodiment, the front shell is a double-layer structure, specifically, the front shell comprises: a lampshade outer plate 1 and a lampshade inner plate 2. The lampshade inner plate 2 is fixedly connected to the inner wall of the lampshade outer plate 1, and the sealing plate 3 is fixedly connected to the lampshade inner plate 2.
[0035] Wherein, the lampshade outer plate 1 is provided with a light-emitting characteristic surface 10; Figure 2 As shown, the inner plate 2 of the lampshade is provided with a light-through groove, and the position of the light-through groove corresponds to the position of the light-emitting characteristic surface 10. That is to say, when the outer plate 1 of the lampshade is provided with light-emitting characteristic surfaces 10 in multiple regions, the inner plate 2 of the lampshade should also be provided with light-through grooves in multiple regions, and the number of the light-through grooves is the same as the number of the light-emitting characteristic surfaces 10, and when the inner plate 2 of the lampshade is fitted and fixed on the outer plate 1 of the lampshade, the position of the light-through groove corresponds to the position of the light-emitting characteristic surface 10, and when the light-emitting unit 5 emits light, the light can pass through the light-through groove, and then pass through the light-emitting characteristic surface 10 to the outside of the position lamp, so that the light is visible outside.
[0036] Furthermore, when the light-emitting characteristic surface 10 is a translucent surface, it can ensure that when the position lamp is not lit, the color of the light-emitting characteristic surface 10 is visible from the outside, and the internal structure of the lamp cavity behind the light-emitting characteristic surface 10 is not visible; when the position lamp is lit, the light passes through the light-emitting characteristic surface 10 to the outside of the lampshade outer plate 1, and the position lamp is visible from the outside. In the light-irradiated area in the lamp cavity, the internal structure close to the light-emitting characteristic surface 10 is visible, and the internal structure far from the light-emitting characteristic surface 10 is not visible. Since no structure is set near the light-emitting characteristic surface 10, that is, in the front cavity 7, even if the internal structure close to the light-emitting characteristic surface 10 is visible, it will not affect the sensory quality when observing the position lamp from the outside.
[0037] In some possible embodiments, the light-emitting characteristic surface 10 on the outer plate 1 of the lampshade is made of a translucent material;
[0038] In some other possible embodiments, the lampshade outer plate 1 is made of a transparent material, and the light-emitting characteristic surface 10 is coated with a translucent coating 11. In this embodiment, the transparent material is a transparent plastic, more specifically, a transparent PMMA material, wherein PMMA is polymethyl methacrylate (Polymethyl Methacrylate), a high molecular polymer, also known as acrylic or organic glass, which has the advantages of high transparency, low price, and easy mechanical processing, and is a commonly used glass substitute material. The translucent coating 11 is a PVD coating, which adopts a vacuum sputtering process. In this embodiment, the PVD coating has a translucent property.
[0039] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.
[0040] The corresponding setting method can be selected according to the usage. It should be noted that no matter which setting method the lampshade outer panel 1 adopts, in this embodiment, the lampshade inner panel 2 needs to be made of non-transparent material, and the non-transparent material is set to non-transparent plastic, more specifically, black PMMA material.
[0041] Therefore, the luminous characteristic surface 10 is a single-layer material surface, that is, only one layer of PMMA is arranged at the luminous characteristic surface 10; a non-luminous characteristic surface is arranged on the front shell, and the non-luminous characteristic surface is a double-layer material surface, and the double layer here includes a layer of PMMA on the outer panel 1 of the lampshade and a layer of PMMA on the inner panel 2 of the lampshade.
[0042] In addition, it is also necessary to reasonably design the depth dimension of the position lamp front cavity 7 to ensure that the distance from the back of the sealing plate 3 to the luminous characteristic surface 10 is greater than the "minimum display distance". Under this condition, when fogging occurs on the back of the sealing plate 3 and the position lamp rear cavity 8, the fog or water droplets are not visible outside the position lamp.
[0043] On the basis of the above embodiment, in this embodiment, in order to enable the front cavity 7 to form a sealed cavity, when the sealing plate 3 is fixed to the front shell, the sealing plate 3 is welded to the inner plate 2 of the lampshade of the front shell. More specifically, the sealing plate 3 is welded to the inner plate 2 of the lampshade by a vibration friction welding process to form a closed front cavity 7. The welding process is completed in a dehumidified environment to ensure that the front cavity of the position lamp is dry and free of moisture. In addition, a sealing gasket can be optionally provided between the sealing plate 3 and the front shell to achieve a sealing effect by adding a sealing gasket. Generally, it is preferred to weld the sealing plate 3 to the inner plate 2 of the lampshade of the front shell.
[0044] Based on the above embodiment, in this embodiment, the vehicle position lamp further includes a diffuser plate 4 , and the diffuser plate 4 is disposed between the front cavity 7 and the rear cavity 8 .
[0045] In this embodiment, the diffuser plate 4 is disposed between the light emitting unit 5 and the sealing plate 3, the top and bottom ends of both sides of the diffuser plate 4 are fixed to the rear shell 6, and a gap is provided between both sides of the diffuser plate 4 and the inner wall of the rear shell 6. The diffuser plate 4 is made of frosted material, and has optical characteristics of plastic plates such as high haze, high light transmittance, and high diffusion, and can effectively convert point or line light sources into soft and uniform surface light sources.
[0046] On the basis of the above embodiment, in this embodiment, the light emitting unit 5 comprises: a lamp holder and a lamp bead 50. The lamp holder is fixed to the rear housing 6, and the lamp bead 50 is fixed to the lamp holder.
[0047] In this embodiment, the lamp holder is fixed to the inner wall of the rear shell 6 and is located between the rear shell 6 and the diffuser plate 4. The lamp bead 50 is fixed on the lamp holder. When the lamp bead 50 is illuminated, the light passes through the diffuser plate 4 and the sealing plate 3, and then passes through the luminous characteristic surface 10, so that the position light is visible from the outside.
[0048] In summary, in the present application, the fogging surface of the position lamp is moved back into the rear cavity 8, and combined with the translucent property of the luminous characteristic surface 10 of the lampshade outer panel 1, it is additionally ensured that the fogging surface is not visible from the outside.
[0049] This application realizes that the position lamp fogging phenomenon will not be visually visible outside the vehicle under any working condition (position lamp off or on) and use environment (environment with different air humidity). Compared with traditional anti-fogging methods, the problem is solved more effectively and thoroughly. There is no need to set a drying bag in the position lamp cavity of this structure, achieving a certain degree of cost reduction. At the same time, this solution can also be further promoted to other similar products.
[0050] In a second aspect, an embodiment of the present application provides a car, which includes the vehicle position light provided by any of the above embodiments of the present application.
[0051] In the present application, the lamp cavity structure of the position lamp is changed, and the lamp cavity is divided into a front cavity 7 and a rear cavity 8 by a sealing plate 3, and the light-emitting unit 5 is arranged inside the rear cavity 8, so that the fogging surface of the position lamp is transferred from the inner surface of the lampshade of the traditional structure to the back of the sealing plate 3 and the rear cavity 8, and the distance between the sealing plate 3 and the light-emitting characteristic surface 10 is set to be greater than the set minimum imaging distance, and the light-emitting characteristic surface 10 is a translucent surface. When the position lamp is not lit, the internal structure of the lamp cavity behind the light-emitting characteristic surface 10 is invisible. When the position lamp is lit, the light is irradiated to the outside of the front shell through the light-emitting characteristic surface 10, and the position lamp is visible from the outside. In the light-irradiated area inside the lamp body, the internal structure close to the light-emitting characteristic surface 10 is visible, and the internal structure far away from the light-emitting characteristic surface 10 is not visible. Therefore, even if the inside of the rear cavity 8 is fogged, since it is far away from the light-emitting characteristic surface 10, the fogging phenomenon of the position lamp will not be visually observed outside the position lamp.
[0052] The overall structure of the vehicle position lamp is shown in Figure 1 As shown, the luminous characteristic surface 10 on the front shell occupies part of the front shell area, and the rest of the front shell area is a non-luminous characteristic surface. The luminous characteristic surface 10 is the area where the light can penetrate the front shell to the outside of the position lamp when the light-emitting unit 5 emits light, so that the light is visible outside.
[0053] In this embodiment, the front shell is a double-layer structure, specifically, the front shell comprises: a lampshade outer plate 1 and a lampshade inner plate 2. The lampshade inner plate 2 is fixedly connected to the inner wall of the lampshade outer plate 1, and the sealing plate 3 is fixedly connected to the lampshade inner plate 2.
[0054] Wherein, the lampshade outer plate 1 is provided with a light-emitting characteristic surface 10; Figure 2As shown, the inner plate 2 of the lampshade is provided with a light-through groove, and the position of the light-through groove corresponds to the position of the light-emitting characteristic surface 10. That is to say, when the outer plate 1 of the lampshade is provided with light-emitting characteristic surfaces 10 in multiple regions, the inner plate 2 of the lampshade should also be provided with light-through grooves in multiple regions, and the number of the light-through grooves is the same as the number of the light-emitting characteristic surfaces 10, and when the inner plate 2 of the lampshade is fitted and fixed on the outer plate 1 of the lampshade, the position of the light-through groove corresponds to the position of the light-emitting characteristic surface 10, and when the light-emitting unit 5 emits light, the light can pass through the light-through groove, and then penetrate the light-emitting characteristic surface 10 to the outside of the position lamp.
[0055] Furthermore, when the light-emitting characteristic surface 10 is a translucent surface, it can ensure that when the position lamp is not lit, the color of the light-emitting characteristic surface 10 is visible from the outside, and the internal structure of the lamp cavity behind the light-emitting characteristic surface 10 is not visible; when the position lamp is lit, the light passes through the light-emitting characteristic surface 10 to the outside of the lampshade outer plate 1, and the position lamp is visible from the outside. In the light-irradiated area in the lamp cavity, the internal structure close to the light-emitting characteristic surface 10 is visible, and the internal structure far from the light-emitting characteristic surface 10 is not visible. Since no structure is set near the light-emitting characteristic surface 10, that is, in the front cavity 7, even if the internal structure close to the light-emitting characteristic surface 10 is visible, it will not affect the sensory quality when observing the position lamp from the outside.
[0056] In some possible embodiments, the light-emitting characteristic surface 10 on the outer plate 1 of the lampshade is made of a translucent material;
[0057] In some other possible embodiments, the lampshade outer plate 1 is made of a transparent material, and the light-emitting characteristic surface 10 is coated with a translucent coating 11. In this embodiment, the transparent material is a transparent plastic, more specifically, a transparent PMMA material, wherein PMMA is polymethyl methacrylate (Polymethyl Methacrylate), a high molecular polymer, also known as acrylic or organic glass, which has the advantages of high transparency, low price, and easy mechanical processing, and is a commonly used glass substitute material. The translucent coating 11 is a PVD coating, which adopts a vacuum sputtering process. In this embodiment, the PVD coating has a translucent property.
[0058] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.
[0059] The corresponding setting method can be selected according to the usage. It should be noted that no matter which setting method the lampshade outer panel 1 adopts, in this embodiment, the lampshade inner panel 2 needs to be made of non-transparent material, and the non-transparent material is set to non-transparent plastic, more specifically, black PMMA material.
[0060] Therefore, the luminous characteristic surface 10 is a single-layer material surface, that is, only one layer of PMMA is arranged at the luminous characteristic surface 10; a non-luminous characteristic surface is arranged on the front shell, and the non-luminous characteristic surface is a double-layer material surface, and the double layer here includes a layer of PMMA on the outer panel 1 of the lampshade and a layer of PMMA on the inner panel 2 of the lampshade.
[0061] In addition, it is also necessary to reasonably design the depth dimension of the position lamp front cavity 7 to ensure that the distance from the back of the sealing plate 3 to the luminous characteristic surface 10 is greater than the "minimum display distance". Under this condition, when fogging occurs on the back of the sealing plate 3 and the position lamp rear cavity 8, the fog or water droplets are not visible outside the position lamp.
[0062] In the present application, the fogging surface of the position lamp is moved back into the rear cavity 8, and combined with the translucent property of the luminous characteristic surface 10 of the lampshade outer panel 1, it is additionally ensured that the fogging surface is not visible from the outside.
[0063] This application realizes that the position lamp fogging phenomenon will not be visually visible outside the vehicle under any working condition (position lamp off or on) and use environment (environment with different air humidity). Compared with traditional anti-fogging methods, the problem is solved more effectively and thoroughly. There is no need to set a drying bag in the position lamp cavity of this structure, achieving a certain degree of cost reduction. At the same time, this solution can also be further promoted to other similar products.
