Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and in particular relates to an integrated thick-walled vehicle lamp. Background Art

[0002] The existing electric vehicle taillight structure is split taillight and combined taillight. In the split taillight, the turn signal and the taillight are separated, and in the combined taillight, the turn signal and the taillight are integrated. According to national requirements, the taillight is red and the turn signal is amber. Most of the combined taillights on the market now require three thick walls to perform different functions, and there is no connection between the thick walls. In order to prevent light crosstalk between the thick walls, baffles are added between the thick walls when assembling the headlight structure to prevent light crosstalk. However, more parts will be generated, the work intensity of workers will increase, and work efficiency will be reduced. As the number of parts increases, the first component and the second component will have tolerances, the second component and the third component will have tolerances, and so on. There will also be tolerances between the Nth component and the N+1th component, which will result in a very large tolerance between the first component and the N+1th component, which will result in non-compliance with the national legal standards for headlights.

[0003] In order to solve the problem of large tolerance caused by too many parts when assembling split rear taillights, a combined rear taillight is proposed. For example, Chinese patent CN201822224467.0 discloses an integrated taillight device, including a taillight base, a lamp shell, a taillight thick-walled part, a lamp bead and a taillight shell; the LED lamp bead is installed on the taillight base; the taillight thick-walled part is buckled on the taillight base; the taillight thick-walled part is installed above the LED lamp bead; the taillight thick-walled part is embedded in the lamp shell; the lamp shell is installed on the taillight thick-walled part; the taillight shell is installed on the lamp shell; the taillight shell is buckled on the taillight base. Although the taillight thick-walled part is an integral injection molding, and multiple groups of bosses are formed on the upper part of the taillight thick-walled part, for the taillight thick-walled part, the lampshade needs to be highly compatible with it to realize the taillight structure, and there is no connection between the thick walls. When the position is realized or the braking and steering are lit at the same time, there will be a gap in the middle to form a dark area, which directly affects the customer's visual sense.

[0004] Chinese patent CN201920516933.4 discloses a car taillight, which includes two thick-walled light guide blocks and two light sources spaced apart from each other. The two light sources are located on the inner sides of the two thick-walled light guide blocks, and the two thick-walled light guide blocks are respectively covered with lampshades, and there is a gap between the two lampshades. Each thick-walled light guide block is provided with a transparent protrusion on the side wall facing the other thick-walled light guide block, and the protrusion is arranged close to the outer side of the corresponding thick-walled light guide block. That is, the extended bright area of ​​the thick wall can be realized through the protrusion, so that the formation of the dark area in the gap in the middle is not so obvious, which can be ignored by the human eye. Compared with the technical solution of Chinese patent CN201822224467.0, it is more beautiful, but the thick wall of this taillight is not formed in one piece, but is a split structure. Utility Model Content

[0005] In view of the above-mentioned prior art, the purpose of the utility model is to provide an aesthetically pleasing and practical integrated thick-walled vehicle lamp.

[0006] The technical solution of the utility model is achieved as follows: an integrated thick wall includes a first thick wall, a second thick wall and a connecting plate, the second thick wall main body structure is extended along an arc in the horizontal direction, a first thick wall gap is provided between the first thick wall and the second thick wall, a first light entrance portion is provided at the rear end of the first thick wall, and a second light entrance portion is provided at the rear end of the second thick wall, the rear ends of the first light entrance portion and the second light entrance portion are connected to the connecting plate so that the first thick wall, the second thick wall and the connecting plate form an integrated structure.

[0007] The beneficial effects of such a design are: using fewer parts to improve assembly accuracy, the first thick wall, the second thick wall and the connecting plate form an integrated structure to reduce errors caused by assembly and avoid the position of the light being offset to affect the appearance, a thinner baffle can be set in the gap between the first thick wall and the second thick wall to avoid the problem of light crosstalk, the thinner baffle will not form an obvious dark area, so that when the taillight and the turn signal light up at the same time after braking using the integrated thick wall, the first thick wall and the second thick wall can form a continuous light, which is more beautiful than the prior art, and the connecting plate is set at the rear end of the first light entrance and the rear end of the second light entrance to avoid light straying or light leakage between the first thick wall and the second thick wall.

[0008] Furthermore, the integrated thick wall also includes a third thick wall, the first thick wall and the third thick wall are located on both sides of the second thick wall, the upper end of the first thick wall and the upper end of the second thick wall are connected by a first connecting protrusion, and the first connecting protrusion is higher than the upper end surface of the first thick wall and the upper end surface of the second thick wall, and the upper end of the third thick wall and the upper end of the second thick wall are connected by a second connecting protrusion, and the second connecting protrusion is higher than the upper end surface of the third thick wall and the upper end surface of the second thick wall. This design makes the first thick wall, the second thick wall and the third thick wall more firmly fixed together, while avoiding light astigmatism or light leakage between the first thick wall, the second thick wall and the third thick wall.

[0009] Furthermore, the first thick wall is provided with a first mounting portion, the second thick wall is provided with a second mounting portion, and the third thick wall is provided with a third mounting portion, so that the installation of the first thick wall, the second thick wall and the third thick wall is convenient.

[0010] Furthermore, a plurality of thick-wall positioning columns are provided at the lower end of the connecting plate, so that the positions of the first thick wall, the second thick wall and the third thick wall are more accurate.

[0011] Furthermore, the second light incident portion is extended along an arc in the horizontal direction, and includes a front triangular wall, a rear triangular wall, a curved wall and a reflective wall. The front triangular wall and the rear triangular wall are located on both sides of the curved wall, and the front triangular wall, the rear triangular wall and the curved wall form a semi-closed structure. The curved wall can gather most of the direct light from the light source at the opening position of the semi-closed structure to the reflective wall and emit it toward the front end of the second thick wall after reflection by the reflective wall. The front triangular wall and the rear triangular wall can reflect most of the oblique light from the light source once or multiple times to the front end of the second thick wall and emit it outward. This design can make the light receiving surface larger, can accommodate more light entering the thick wall, and the light is more uniform. The light source can be set on the side of the thick wall, and there can be more space to set the light source. It is compatible with more light sources and circuit boards, can increase the power of the light source, and meet more design requirements.

[0012] Furthermore, the cross-sections of the first light entrance portion, the third light entrance portion and the second light entrance portion adopt the same design, the first light entrance portion is further extended from the second light entrance portion in the horizontal direction along an arc, then bent at a certain angle to the front end of the first thick wall, and then extended a certain distance, the third light entrance portion is further extended from the second light entrance portion in the horizontal direction along an arc, then bent at a certain angle to the front end of the third thick wall, and then extended a certain distance. Since the first thick wall, the second thick wall and the third thick wall are arranged in an arc shape, the left turn signal is easy to observe on the left side but not on the right side. The same problem exists for the right turn signal. The bending design at the end of the first light entrance portion and the third light entrance portion can take into account observers from different directions, so that the signal of the signal light is more obvious and easier to observe, so as to provide a better warning to others.

[0013] Furthermore, the front end of the first thick wall, the front end of the second thick wall and the front end of the third thick wall are all provided with an upwardly protruding arc-shaped scattering portion. The first thick wall, the second thick wall and the third thick wall are relatively thin and long. If no scattering structure is designed, the range of light emitted by the first thick wall, the second thick wall and the third thick wall is relatively limited. The provision of an arc-shaped scattering portion allows factory operators at more angles to see more obvious signals.

[0014] Furthermore, the width of the first thick wall gap gradually decreases from the rear end to the front end so that the light from the first thick wall and the light from the second thick wall can intersect at a certain position before the front end. In this design, there will be no obvious dark area between the lights. When multiple lights are turned on at the same time, the integrated structure is more beautiful, which is in line with the current development trend of car lights and is more popular.

[0015] The vehicle lamp comprises at least the above-mentioned integrated thick wall, a light source and a decorative part. The decorative part directly or indirectly limits the light source and the integrated thick wall. The integrated thick wall assembly has low cost and the vehicle lamp is more beautiful and practical.

[0016] Furthermore, the decorative component is provided with a first baffle and a second baffle, the first baffle is complementary to the gap of the first thick wall, the second baffle is complementary to the gap of the second thick wall, the height of the first baffle and the second baffle is the same as the thickness of the corresponding position of the second thick wall to ensure that the light between the first thick wall, the second thick wall and the third thick wall will not crosstalk, the rear ends of the first baffle and the second baffle extend downward to isolate the light sources of the first thick wall, the second thick wall and the third thick wall, the first baffle and the second baffle form a certain angle, the angle range is -10° to 30°, which has a better effect of preventing light leakage and crosstalk.
