Description

Technical Field

[0001] The invention relates to a vehicle lamp structure capable of controlling the light-emitting interval and a vehicle. Background Art

[0002] Considering the artistic modeling, more and more automotive lamps are becoming more artistic in modeling while meeting the special requirements of modeling and lighting mode, and thus adopting more artistic design methods. How to realize artistic modeling in traditional automotive lamps and meet the modeling requirements of automotive lamps as much as possible and meet the requirements of customers has become a new trend in modeling.

[0003] For the existing headlight structure, if the lighting interval of the narrow lighting area can be effectively controlled, and at the same time, the light leakage and light channeling problem of each lighting area can be effectively controlled while using this lighting interval, it becomes a way that needs to be changed and innovated, and then the way of changing and solving this light channeling can be changed, so that the sense of lines can be felt from any angle, which is conducive to achieving a more special lighting effect, satisfying the OEM's pursuit of innovative effects, and at the same time, it can make the product have a certain control in terms of cost, and only through this special process can special effects be achieved. It has become a technology development trend that OEMs are increasingly yearning for.

[0004] The traditional implementation method is to use hard "T"-shaped ribs of decorative rings to control the light leakage and channeling problems between parts. However, this kind of hard PC, PMMA, PBT and other materials will inevitably lead to a certain gap between the fixation of products, which will lead to the need to retain a "C"-shaped design structure between the two light leakage and channeling gaps. Due to the design of the mold and the characteristics of the product, this "C"-shaped structure needs to ensure that the gap between the two light-emitting areas is at least greater than 6mm, which leads to the product's light-emitting interval being too large, affecting the realization of special product shapes and special needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the problems of light leakage and light crossing and too large gaps between light-emitting areas in the prior art, and to provide a vehicle lamp structure that can effectively control the intervals between light-emitting areas.

[0006] The technical problem to be solved can be implemented through the following technical solutions.

[0007] A vehicle lamp structure capable of controlling the light emission interval, including a vehicle lamp body and a light distribution mirror, is characterized in that inside the vehicle lamp body, a partition support body is provided. The inner side of the partition support body is a light-emitting light source. The main body of the partition support body is composed of a plurality of partitions arranged side by side. The space between adjacent partitions is a hollow area. The light of the inner light-emitting light source forms a plurality of side-by-side light-emitting areas after passing through the hollow areas formed between each of the side-by-side partitions, and the light is directed to the light distribution mirror by a main decorative ring that abuts against the partition support body; wherein, the partition support body is in flexible abutment with the main decorative ring through the partitions.

[0008] As a further improvement of this technical solution, the light-emitting light source is one or more light sources on a light-emitting light source circuit board, and the partition support body is positioned on the light-emitting light source circuit board.

[0009] As one of the preferred embodiments of the present invention, the partition has a base, and the base and the partition are two-color or three-color injection molded parts, and the part thereof that abuts against the main decorative ring is an EPDM material injection molded part or a PUR material injection molded part.

[0010] More preferably, the base is a PP material injection molded part.

[0011] As a further improvement of this technical solution, the light-emitting light source circuit board is an LED circuit board.

[0012] Also as a further improvement of this technical solution, the main decorative ring is provided with a plurality of strip-shaped light-emitting surfaces, and each strip-shaped light-emitting surface corresponds to one of the hollow areas.

[0013] Also as one of the preferred embodiments of the present invention, the main decorative ring is a two-color injection molded part composed of a first color and a second color, and respectively forms the strip-shaped light-emitting surface and the abutting part that abuts against the partition.

[0014] Furthermore, the first color part extends into the hollow area formed between the partitions.

[0015] Another technical problem to be solved by the present invention is to provide an automobile adopting the above vehicle lamp structure capable of controlling the light emission interval.

[0016] Another technical problem to be solved by the present invention is to provide an automobile structure adopting the above vehicle lamp structure capable of controlling the light emission interval as a position lamp.

[0017] The vehicle lamp structure with controllable light emission intervals and the vehicle adopting the above technical solution divide the light-emitting area into multiple set light-emitting areas such as strip-shaped areas without light leakage or light crosstalk by using a partition-type support body and relying on the interference-fit flexible cooperation between the partition and the main decorative ring. In terms of the effect, compared with the old implementation method, the new implementation method makes the shape more flexible and more artistic in the overall vehicle exterior layout, changes and solves the structural method of light crosstalk, and feels this sense of line from any angle, which is beneficial to achieving a relatively special lighting effect, beneficial to the pursuit of innovation effects by the vehicle manufacturer, and at the same time can control the cost of the product to a certain extent; that is, through this special structure and its process treatment method, special effects are achieved, and the purpose of controllable light emission intervals is achieved. Brief Description of the Drawings

[0018] Figure 1 Structural schematic of a strip-shaped light-emitting area;

[0019] Figure 2 is Figure 1 The sectional view taken along the line A-A in [reference figure], and schematically shows the vehicle lamp structure of the present invention; Detailed Description of the Preferred Embodiments

[0020] The following further details the specific embodiments of the present invention with reference to the accompanying drawings.

[0021] As Figure 1 shown, the strip-shaped area 31 is the light-emitting area of the lamp. The interval of this kind of light-emitting area is only in the range of 1.5 mm - 2 mm. At this time, it is impossible to control the light emission interval of the product using the traditional scheme while ensuring no light leakage or light crosstalk between the light-emitting areas.

[0022] As Figure 2 shown, the vehicle lamp structure with controllable light emission intervals, 1 is the light distribution mirror, 2 is the lamp body, 3 is the main decorative ring, which contains a strip-shaped light-emitting surface (i.e., the strip-shaped area 31), 4 is the LED circuit board assembly, 5 is the circuit board support, and the selected material is a PP material (i.e., the base 51) that can be combined with EPDM rubber. 6 (i.e., the partition 53) is an EPDM rubber part. Among them, 5 and 6 are a two-color injection molded part. The key characteristic of this part is to use EPDM material for structural sealing. Since EPDM material is a flexible material, it can completely fit to the front main decorative ring 3 and has a slight interference with the mating part 32 of the main decorative ring 3, which can ensure that there is no relevant light leakage or light crosstalk gap between the light-emitting areas and avoid the gap caused by hard contact in the traditional implementation method. This design scheme must use a two-color or three-color circuit board support for control, and as the blocking part material, a flexible material such as EPDM or PUR material is used.

[0023] Specifically, the LED circuit board 4 provides a light source, which is located inside the circuit board bracket 5 (the left side in the figure). The circuit board bracket 5 is divided into multiple regions for guiding and dividing light by partitions 53 made of a plurality of light-impermeable materials. The bottom of the partition 53 is a base 51, and the hollow regions 50 formed between adjacent partitions are the route regions for the light source to travel. The light emitted by one or more light sources provided by the LED circuit board 4 passes through the multiple hollow regions 50 and is divided by the base 51 and the partitions 53 and then emitted to the light distribution lens 1 along the strip-shaped regions 31 on the corresponding main decorative ring 3, forming multiple light-emitting regions of a set shape (such as strip-shaped). To prevent light leakage and crosstalk, at the place where the right side of each partition 53 in the figure cooperates with the main decorative ring 3 (i.e., the cooperation part 32 in the figure), the partition 53 is injection-molded from a flexible material and has an appropriate interference fit (i.e., elastic abutment) with the cooperation part.

[0024] Moreover, the main decorative ring 3 is a two-color part, forming a light-emitting region (strip-shaped region 31) and a cooperation part 32 respectively, and the strip-shaped region 31 can extend into the gap between the partitions.

[0025] This method can not only be applied to the same function of position lights, but also to the implementation method of preventing light leakage and crosstalk between different functions. The design method of the product can also be applied to components such as internal light distribution lenses that require light blocking, so as to achieve a better lighting effect at the same cost.
