Description

Technical Field

[0001] The invention relates to a vehicle lamp light-emitting component structure, in particular to a vehicle lamp ring-shaped light-emitting component. Background Art

[0002] At present, in order to meet the needs of styling and special requirements of lighting methods, more and more automotive lamps are becoming more artistic and using more artistic design methods. How to realize artistic styling in traditional automotive lamps to meet the styling needs of automotive lamps as much as possible and meet the requirements of customers has become a new trend in styling. Styling can increase the artistic sense of styling to a greater extent.

[0003] At this time, if a lamp can be designed to be used in the front bumper and grille area of ​​the car, the personalized needs of the car can be greatly improved. Many vehicles can be personalized and family-style front face designed, and can achieve family-style identification at night through optical effects, which is beneficial to the OEM's pursuit of innovative effects and can achieve special effects only by designing a new special luminous lamp that can be applied to the front bumper and grille.

[0004] However, due to the extremely narrow structure of the light emitting device, it is difficult to design a sealed structure for the product. General design solutions cannot achieve layout in a narrow space. According to the existing headlight structure design, it is unable to meet the compact space requirements of the bumper and grille. Summary of the invention

[0005] The object of the present invention is to provide a light-emitting component structure of a vehicle lamp, which is suitable for locations with narrow spaces such as front bumpers and grilles, and at the same time, the structure is ingeniously sealed.

[0006] The present invention adopts the following technical solutions:

[0007] A ring-shaped light-emitting component of a vehicle lamp comprises a light guide 5, a luminous thick-walled inner light distribution mirror 2, an external mask 1, and a lamp body 4; the thick-walled inner light distribution mirror 2 is ring-shaped as a whole, and the front end of its cross section has a front convex portion corresponding to the light guide 5, the rear corresponding to the front convex portion has a first reflecting bevel, and the part laterally corresponding to the first reflecting surface has a second reflecting bevel, and the front part opposite to the second reflecting bevel is a light emitting surface; a first sealing area is formed between the external mask 1 and the thick-walled inner light distribution mirror 2 through two welding parts, and the light guide 5 is located in the first sealing area; a second sealing area is formed between the thick-walled inner light distribution mirror 2 and the lamp body 4 through two gluing parts, and the first reflecting bevel and the second reflecting bevel of the thick-walled inner light distribution mirror 2 are located in the second sealing area.

[0008] Preferably, the welding portion B and the light emitting surface are located in the same plane, and the welding portion A is located relative to the welding portion B and is located at the periphery of the annular light-emitting component of the lamp.

[0009] Furthermore, the two welding locations are sealed by laser welding structures.

[0010] Preferably, the thick-walled inner light distribution mirror 2 is made of PC or PMMA clear material, and the outer mask 1 is made of PC, or PC and ABS material.

[0011] Preferably, in the two gluing locations, the thick-walled inner photometric mirror 2 has two gluing feet, which are respectively arranged at two ends of the cross section of the thick-walled inner photometric mirror, and the corresponding location of the lamp body is a glue arrangement area with a "concave" structure.

[0012] Preferably, the annular light-emitting component of the vehicle lamp is arranged at the grille of the vehicle, and the external mask 1 is a part of the grille of the vehicle.

[0013] Preferably, the annular light-emitting component of the headlight is arranged at the front bumper of the car, and the external mask 1 is a part of the front bumper of the car.

[0014] The beneficial effects of the present invention are:

[0015] 1) The structure is more ingenious, the design space is greatly reduced, and the layout design of the sealed structure can be carried out in a small space, which solves the problem of difficult sealing of grille-type lamps.

[0016] 2) The structure is compact, and the light guide is set in a narrow space. The light guide is shielded by the front external mask, making the light guide invisible, avoiding the scattering pattern on the light guide from affecting the aesthetics of the headlight when it is not lit;

[0017] 3) The sealing structure is cleverly designed: two welding locations are used to seal the light guide, and two gluing locations are used in combination with a concave-convex structure design to seal the first and second reflective bevels on the back of the thick-walled internal light distribution mirror, preventing them from being affected by dust and other dirt that may affect the light quality.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] See also Figure 1-Figure 5 A ring-shaped light-emitting component of a vehicle lamp comprises a light guide 5, a luminous thick-walled inner light distribution mirror 2, an external mask 1, and a lamp body 4; the thick-walled inner light distribution mirror 2 is annular as a whole, and the front end of its cross section has a front convex portion corresponding to the light guide 5, the rear corresponding to the front convex portion has a first reflecting bevel, and the part corresponding to the first reflecting surface laterally has a second reflecting bevel, and the front part opposite to the second reflecting bevel is a light emitting surface; a first sealing area is formed between the external mask 1 and the thick-walled inner light distribution mirror 2 through two welding parts, and the light guide 5 is located in the first sealing area; a second sealing area is formed between the thick-walled inner light distribution mirror 2 and the lamp body 4 through two gluing parts, and the first reflecting bevel and the second reflecting bevel of the thick-walled inner light distribution mirror 2 are located in the second sealing area.

[0026] At this time, the sealing design is divided into two areas for control, such as Figure 2 , welding part A in 3, welding part B is the sealing area between the thick-walled inner light distribution mirror 2 and the external mask 1. The design scheme selected for this area is laser welding structural sealing, which is characterized by the huge drop of the incident light of the two laser weldings. It is necessary to control the energy of the laser welding equipment to give different welding energies to the thick-walled area and the thin-walled area respectively. The thick-walled inner light distribution mirror 2 uses PC or PMMA clear material, and the external mask 1 uses PC or PC + ABS, ABS black material. At this time, the laser welding principle can transfer the energy of the clear area to weld the clear and black parts. This time, the sealing structure of the thick-walled inner light distribution mirror 2 and the external mask 1 is completed.

[0027] The second sealing area is the fixation between the thick-walled inner light distribution mirror 2 and the lamp body 4, such as Figure 3As shown in the middle glue area A and glue area B, the thick-walled internal light distribution mirror is designed with two glue feet, which are designed on both sides of the cross section, and the lamp body is designed as a glue arrangement area with a "concave" structure. The glue can be a reactive hot melt adhesive or room temperature curing silicone. The lamp body after glue is arranged on the lower side of the mold, and then the thick-walled internal light distribution mirror and the external mask assembly are installed on the upper side to finally achieve a sealed method. The first reflective bevel and the second reflective bevel of the thick-walled internal light distribution mirror 2 are important functional parts of the thick-walled internal light distribution mirror 2. Therefore, this sealing method can ensure that it is not contaminated by dust and dirt, and the structure is also compact.

[0028] In this embodiment, see Figure 2 The welding part B and the light emitting surface are located in the same plane, and the welding part A is located relative to the welding part B and is located at the periphery of the annular light-emitting component of the lamp.

[0029] In this embodiment, the two welding locations are laser welded structural seals.

[0030] In this embodiment, the thick-walled inner light distribution mirror 2 is made of PC or PMMA material, and the outer mask 1 is made of PC, or PC and ABS material.

[0031] In this embodiment, see Figure 3 Among the two glue-laying locations, the thick-walled inner light distribution mirror 2 has two glue-laying feet, which are respectively arranged at the two ends of the cross section of the thick-walled inner light distribution mirror, and the corresponding part of the lamp body is a glue arrangement area with a "concave" structure.

[0032] In this embodiment, see Figure 1-4 The annular light-emitting component of the lamp is arranged at the automobile grille, and the external mask 1 is a part of the automobile grille. In the traditional implementation method, the function of the grille is to be beautiful in appearance and provide gas guidance, so that the design efficiency of the cooling water tank is higher. Some grilles are combined with the function of active air intake, and the size of the grille air holes is controlled by electronic control. That is, when the car is cooled, the air intake function is turned off, so that the product reaches the working temperature more quickly. At this time, the air intake grille is opened to enable it to work stably. This traditional application function can only meet the solution of the working temperature of the water tank, but it does not take into account that the product can be combined with automobile lamps. Through the above structural design, the grid can be combined with the automobile lamps, and its sealing characteristics are met during the lamp combination process.

[0033] In another embodiment, the annular light-emitting component of the car lamp is arranged at the front bumper of the car, and the external mask 1 is a part of the front bumper of the car.

[0034] The above are preferred embodiments of the present invention. Ordinary technicians in this field can also make various changes or improvements on this basis. Without departing from the overall concept of the present invention, these changes or improvements should fall within the scope of protection required by the present invention.
