Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, in particular to a light guide flowing water vehicle lamp structure. Background Art

[0002] In order to make the lamps used on automobiles have a dazzling effect to attract consumers and increase the selling points of automobiles. At present, there are already chips developed for the dynamic flowing water requirements of automobile lamps in the automotive chip market, which have certain advantages in some aspects. However, for the design scheme of automotive dynamic flowing water lamps implemented based on chips, considering only the cost of circuit components, the cost is relatively high. Moreover, the dynamic flowing water lamps designed based on chips mainly rely on software control, which requires investment in software technology, increasing the R & D cost. At the same time, the dynamic flowing water lamps relying on chip design need to use a large number of connecting wires to connect the chip with the LED lamp group, power supply and drive circuit.

[0003] In this regard, the patent publication number CN209819434U discloses a multi-light guide flowing water vehicle lamp structure, which requires a thick-walled optical part to cooperate with a long light guide and several short light guides to achieve the flowing water effect by sequentially lighting the short light guides. After research, it is found that the vehicle lamp structure still has the following problems:

[0004] First of all, compared with the dynamic flowing water effect achieved by chip control, although it can reduce the chip cost, the cooperation of the long light guide and several short light guides requires a large number of optical parts to be assembled, the assembly is cumbersome, and the assembly cost is high; moreover, the cooperation of multiple optical parts also increases the weight of the overall structure synchronously.

[0005] Secondly, for several short light guides, the light-emitting points of their one-to-one cooperation are located on different planes respectively. This structure also requires the PCB board for cooperating with multiple light-emitting points to adopt a flexible board structure, and the flexible PCB board has the disadvantage of high cost compared with the rigid PCB board.

[0006] Therefore, considering from the perspective of simultaneously simplifying optical parts and reducing chip cost, it is necessary to further improve the vehicle lamp structure that can achieve the flowing water dynamic effect. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a light guide flowing water vehicle lamp structure to solve the technical problem of simplifying the structure and reducing the comprehensive cost.

[0011] At least two light emitting members, which are adapted to be arranged corresponding to the light incident ends of the at least two light mixing parts one by one;

[0012] The light emitted by each light emitting member enters from the light incident end of the light mixing part, undergoes total reflection in the light mixing part, and then exits from the light emitting part of the light guide member.

[0013] In an optional implementation case of the present utility model, the light guide member includes 4 to 8 light mixing parts.

[0015] In an optional implementation case of the present utility model, the radian of the light incident part is greater than the radian of the light guide part.

[0016] In an optional implementation case of the present utility model, an interval area is formed between every two adjacent light mixing parts.

[0017] In an optional implementation case of the present utility model, the light guide flowing water lamp structure further includes a bracket for snap-fitting with the light guide member; and

[0018] The bracket is provided with positioning protrusions adapted to be inserted one by one into the interval areas between every two adjacent light mixing parts.

[0019] In an optional implementation case of the present utility model, the light guide flowing water lamp structure further includes a decorative ring provided on the side of the light emitting part facing away from the light mixing part, and a lamp cover provided on the outside of the decorative ring.

Therefore, the assembly process of the light guide flowing water lamp structure can be simplified, the assembly difficulty can be reduced, and thus the assembly cost can be reduced. Furthermore, for the light guide member adopted, the light incident ends of its multiple light mixing parts are directly designed on the same plane. In this way, for the PCB boards of the multiple light emitting parts that cooperate with the light incident ends, a rigid board structure can be directly adopted, so the cost of the PCB boards to be used can be reduced.

[0028] In order to make the content of the utility model easier to be clearly understood, the following further detailed description of the utility model is given according to specific embodiments in conjunction with the drawings.

[0029] Please refer to Figures 1 to 3 As shown, this embodiment provides a light guide flowing water lamp structure, including: a light guide member, a bracket 1 for fixing the light guide member, and a light emitting member 2, a decorative ring 4, and a lamp cover 5 that cooperate with the light guide member.

[0030] Specifically, first is the light guide member, which includes a light guide rod extending in a strip shape, at least two light mixing parts arranged at intervals and integrally connected to the light guide rod, and at least two light emitting parts 31 formed on the light guide rod corresponding to at least two light mixing parts one by one. It should be noted here that regarding the shape of the light guide rod here, it can be a regular straight rod shape or a rod shape with a slight arc, and it is designed according to the specific requirements of the shape of the vehicle lamp in this structure. This embodiment does not make an absolute limitation on this.

[0031] In terms of materials, the light guide member is made of PC material or PMMA material. The bracket 1 among them can be made of white material.

[0032] Here, in combination with the accompanying drawings, an optional case is exemplified. The light guide member adopted in this embodiment includes 4 to 8 light mixing parts. Regarding these several light mixing parts, a plurality of light emitting parts 31 corresponding to each light mixing are required. Here, it means that the entire light guide rod is segmented into a plurality of light emitting parts 31.

[0033] On the basis of the above structure, it should also be noted that the 4 to 8 light mixing parts are all located on the same side end in the length direction of the light guide rod, and the light incident ends 34 of the 4 to 8 light mixing parts are located on the same horizontal plane. A light emitting member 2 is correspondingly arranged at each light incident end 34. In this way, for the PCB board 6 of the plurality of light emitting members 2 cooperating with the light incident ends 34, a rigid board structure can be directly adopted, so the cost of the PCB board 6 to be adopted can be reduced. In this structure, the light emitted by each light emitting member 2 enters from the light incident end 34 of the light mixing part, undergoes total reflection in the light mixing part, and then exits from the light emitting part 31 out of the light guide member. The light emitting member 2 here can be selected, for example but not limited to, an LED lamp.

[0034] More specifically, each light mixing part in this embodiment includes a light guide part 32 that is arc-shapedly connected to the light emitting part 31, and an arc-shaped light incident part 33 provided on the side of the light guide part 32 facing away from the light mixing part; the light incident end 34 is formed on the light incident part 33. The radian of the light incident part 33 is greater than the radian of the light guide part 32. In this structure, for the overall light guide member, it can be understood as a tree-like structure. The light guide rod is the main trunk of the tree, and the plurality of light mixing parts are equivalent to the branches of the tree, and the plurality of branches are located on the same side end face of the main trunk.

[0035] In addition, it should also be noted that a spacing area 35 is formed between every two adjacent light mixing parts. Exemplifying an optional case, the light guide member and the bracket 1 are matched in a snap-fit manner. For this, positioning protrusions 11 are provided on the bracket 1 and are adapted to be inserted one by one into the spacing area 35 between every two adjacent light mixing parts.

[0036] Furthermore, regarding the decorative ring 4, it is assembled with the bracket 1 by means of snap-fasteners or screws. And the decorative ring 4 is arranged on the side of the light emitting part 31 facing away from the light mixing part, and the lamp cover 5 is arranged outside the decorative ring 4. In addition, at least two light emitting areas corresponding to at least two light emitting parts 31 are formed on the decorative ring 4.

[0037] Such as Figure 1As shown in the figure, the light guide member includes 5 light-emitting portions 31. Correspondingly, the decorative ring 4 is also divided into 5 light-emitting areas, and 5 light-emitting components 2 are required. There are 5 flowing water effects. When each light-emitting portion 31 of the light guide member is longer, the number of segments of the corresponding light-emitting portion 31 is smaller, the number of light-emitting areas of the decorative ring 4 will decrease, the number of light-emitting components 2 will also decrease, and the number of flowing water effect lines will also decrease. When each light-emitting portion 31 of the light guide member is shorter, the number of segments of the corresponding light-emitting portion 31 is larger, the number of light-emitting areas of the decorative ring 4 will increase, the number of light-emitting components 2 will also increase, and the number of flowing water effect lines will also increase, and the flowing water effect is richer. Therefore, the flowing water effect can be adjusted correspondingly according to requirements.

[0038] In summary, for the light guide flowing water vehicle lamp structure of this embodiment, the light mixing portion and the light-emitting portion 31 included in the light guide member are of an integrated structure and can be integrally assembled onto the bracket. Therefore, the assembly process of the light guide flowing water vehicle lamp structure can be simplified, the assembly difficulty can be reduced, and thus the assembly cost can be reduced. By controlling the lighting sequence of multiple light-emitting components 2, the flowing water effect can be achieved. The cost of the corresponding circuit control is also relatively low. Therefore, overall, the light guide flowing water vehicle lamp structure of this application can reduce its production cost while achieving the dynamic flowing water effect.
