Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, in particular to a side-emitting vehicle lamp module. Background Art

[0002] Most vehicle lighting groups use LEDs as light sources. The emitted light is first coupled into a light guide structure of a specific shape to form a light path of a specific shape, and then combined with the thick-walled parts on the light-emitting side of the light guide structure to achieve a personalized lighting effect for the vehicle lights.

[0003] As an optical component that realizes the optical signal function, the thick-walled part utilizes the total reflection of light and has the characteristics of being beautiful, novel and efficient. In the prior art, the thick-walled parts used in the headlights are mostly one-piece structures, which occupy a high space of the headlights and have high production costs. For example, the LED thick-walled light guide corner lamp disclosed in the announcement number CN211502619U, in which the thick-walled light guide is close to the LED circuit board, has a large overall size, and requires a large space for assembly. The headlights using this structure are difficult to be applied in small space scenarios.

[0004] Therefore, given the problem that the thick-walled structure currently commonly used in car lights is large in size and requires a large space for assembly and is not suitable for small space scenes, it is necessary to optimize the structure of the car lights used in small space scenes. Utility Model Content

[0005] The purpose of the utility model is to provide a side-emitting vehicle lamp module to solve the technical problem of improving its applicability to small space scenes.

[0006] The side-emitting lamp module of the utility model is realized as follows:

[0007] A side-emitting vehicle lamp module, comprising:

[0008] A thick-walled assembly, comprising a thick-walled bracket and a pair of thick-walled members symmetrically fixed on the thick-walled bracket; the thick-walled bracket comprises a U-shaped bracket body and a pair of hollow areas formed on two opposite side walls of the U-shaped bracket body; the pair of thick-walled members are arranged one-to-one on the two side walls of the U-shaped bracket body to cover the hollow areas;

[0009] The light source assembly comprises a U-shaped LED circuit board connected to a U-shaped bracket body, and two LED light-emitting units arranged on the LED circuit board and adapted to correspond one-to-one to a pair of light-incoming ends of thick-walled parts.

[0010] In an optional implementation of the present invention, each of the thick-walled parts is made of a transparent material.

[0011] In an optional implementation of the present invention, the U-shaped bracket body is semi-enclosed to form a cavity; and

[0012] Each of the thick-walled parts is provided with optical reflective teeth on the side wall facing the cavity.

[0013] In an optional implementation of the present invention, the arrangement density of the optical reflective teeth is distributed from dense to sparse from the end adjacent to the light incident end to the end away from the light incident end.

[0014] In an optional implementation of the utility model, each of the thick-walled members includes an integrally formed light-guiding portion and a pair of oppositely disposed connecting portions disposed on the light-guiding portion;

[0015] A pair of connecting parts are arranged on a pair of side walls of the light guide part which are perpendicular to the light incident end;

[0016] A pair of connecting parts is used to connect with the U-shaped bracket body.

[0017] In an optional implementation of the present invention, one of the pair of connecting parts includes a connecting plate connected to the light guide part by bending and at least one mounting hole formed on the connecting plate; and

[0018] The other connecting portion includes at least one protruding positioning column arranged on the side wall of the light guiding portion.

[0019] In an optional implementation of the present invention, the U-shaped bracket body is provided with a mounting column adapted to the mounting hole and a positioning hole adapted to the positioning column.

[0020] In an optional implementation of the utility model, the end surface of the U-shaped bracket body facing the LED circuit board is provided with a folded fixing portion; and

[0021] The fixing portion and the LED circuit board are suitable for being connected by snapping.

[0022] In an optional implementation of the utility model, a hollow groove corresponding to the LED light-emitting unit is formed on the fixing portion, so that the light emitted by the LED light-emitting unit can pass through the hollow groove and then enter the light incident end of the thick-walled member.

[0023] In an optional implementation of the present invention, the light incident end of the thick-walled member is provided with a striped pattern.

[0024] By adopting the above technical solution, the utility model has the following beneficial effects: in the side-emitting headlight module of the utility model, a pair of thick-walled parts and a thick-walled bracket form a thick-walled assembly and then cooperate with the light source assembly. The light emitted by the LED light-emitting unit is incident through the light-incoming end of the thick-walled part, and the side of the headlight module can be evenly lit with a small number of light sources. For the overall thick-walled parts, a split design structure is adopted, and a suitable light source assembly is matched. For the side-emitting case, the split design structure is not only smaller in size than the integral structure, which reduces the production cost, but also requires less assembly space, thereby reducing the overall size of the overall headlight module, so that it can be suitable for assembly in scenes with limited space. Therefore, the side-emitting headlight module of the utility model can achieve a uniform lighting effect with a smaller space and lower cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0034] See also Figures 1 to 7 As shown, this embodiment provides a side-light-emitting vehicle lamp module, including: a thick-wall component and a light source component used in conjunction with each other.

[0035] Specifically, the first is a thick-walled component, which includes a thick-walled bracket and a pair of thick-walled parts symmetrically fixed on the thick-walled bracket. The pair of thick-walled parts here are mainly located at the side light output positions of the overall side-emitting lamp module. The thick-walled bracket is used to fix the thick-walled parts on the one hand, and is also used to fix the light source assembly on the other hand.

[0036] In more detail, the thick-walled bracket used in this embodiment includes a U-shaped bracket body 3, and a pair of hollow areas 31 formed on two opposite side walls of the U-shaped bracket body 3; the two opposite side walls here correspond one-to-one to the side light emitting positions of the overall side-emitting lamp module. A pair of thick-walled parts are arranged one-to-one on the two side walls of the U-shaped bracket body 3 to cover the hollow areas 31. The design of the hollow areas 31 here can reduce the material cost of the thick-walled bracket on the one hand, and reduce the weight of the thick-walled bracket on the other hand, thereby reducing the total weight of the overall side-emitting lamp module.

[0037] Furthermore, the U-shaped bracket body 3 is half-enclosed to form a cavity 38. The design of the cavity 38 here can also reduce the material cost of the thick-wall bracket on the one hand, and can also reduce the weight of the thick-wall bracket on the other hand.

[0038] Regarding the thick-walled parts used in this embodiment, it should also be noted that each thick-walled part is made of a transparent material such as but not limited to PC or PMMA. Each thick-walled part is provided with an optical reflective tooth 11 on the side wall facing the cavity. The arrangement density of the optical reflective teeth 11 is distributed from dense to sparse from the end adjacent to the light-entering end 12 to the end away from the light-entering end 12, so as to improve the problem of uneven lighting of the single-sided light-entering structure. The light-entering end 12 of the thick-walled part is provided with a striped pattern, which is conducive to the transmission of direct light in the thick-walled part according to the shaping trend.

[0039] Regarding the assembly and fixing method between the thick-walled part and the thick-walled bracket, this embodiment adopts the following structure:

[0040] Generally, the thick-walled component is firstly assembled with the thick-walled bracket by a snap-fitting structure to realize the preliminary positioning of the thick-walled component. To this end, each thick-walled component includes an integrally formed light guide portion 1 and a pair of oppositely disposed connecting portions disposed on the light guide portion 1; the pair of connecting portions are disposed on a pair of side walls of the light guide portion 1 perpendicular to the light input end 12; the pair of connecting portions are used to connect with the U-shaped bracket body 3.

[0041] In more detail, one of the pair of connecting parts includes a connecting plate 21 connected to the light guide 1 by bending and at least one mounting hole 22 formed on the connecting plate 21; and the other connecting part includes at least one positioning column 23 provided on the side wall of the light guide 1 in a convex shape. Correspondingly, the U-shaped bracket body 3 is provided with a mounting column 32 adapted to the mounting hole 22 and a positioning hole 33 adapted to the positioning column 23. Based on this structure, a positioning structure for fixing the thick-walled part is formed by the cooperation between the mounting column 32 and the mounting hole 22, and the cooperation between the positioning column 23 and the positioning hole 33, and then the positioning structure is welded and fixed by, for example, but not limited to, ultrasonic welding, so that the thick-walled part is firmly assembled on the thick-walled bracket.

[0042] Next, about the light source component:

[0043] Structurally, the light source assembly includes a U-shaped LED circuit board 4 connected to a U-shaped bracket body 3, and two LED light-emitting units 5 arranged on the LED circuit board 4 and adapted to correspond one-to-one to a pair of light-entering ends 12 of the thick-walled member. Each LED light-emitting unit 5 here includes a plurality of light-emitting lamps arranged at intervals, and the interval distribution method enables the uniform lighting of the side of the vehicle light module to be achieved with a relatively small number of light-emitting lamps.

[0044] Based on the above situation, let's talk about the assembly problem between the light source assembly and the thick-walled bracket:

[0045] First, the end surface of the U-shaped bracket body 3 facing the LED circuit board 4 is provided with a folded fixing portion 35; the fixing portion 35 is connected to the LED circuit board 4 by being adapted for clamping. For example, a clamping hole 41 is preset on the LED circuit board 4, and a clamping column 37 adapted to the clamping hole 41 is provided on the end surface of the U-shaped bracket body 3 facing the LED circuit board 4. Based on this structure, the LED circuit board 4 is fixed by clamping, and then the LED circuit board 4 is firmly fixed between the lamp base and the thick-walled bracket by assembling and fixing the side-emitting lamp module of this embodiment with, for example, the lamp base.

[0046] Secondly, it should be explained that a hollow groove 36 corresponding to the LED light-emitting unit 5 is formed on the fixing portion 35 so that the light emitted by the LED light-emitting unit 5 can pass through the hollow groove 36 and then be incident on the light-incoming end 12 of the thick-walled member.

[0047] In addition, regarding the side-emitting headlight module of this embodiment, it is also necessary to explain that the outer side of the thick-walled bracket and the thick-walled member is surrounded by a decorative ring cover 6. The decorative ring cover 6 here can be optionally processed and formed by a two-color material. Generally, the decorative ring cover 6 is formed by combining a black sheet 61 and an opal sheet 62, wherein the opal sheet 62 covers the outer layer of the thick-walled member, and a modeling pattern 63 can be provided on the outer side of the opal sheet 62. The decorative ring cover 6 here is used to assemble the LED light-emitting unit 5, the thick-walled bracket and the thick-walled member together to form an external light-shielding enclosure. The decorative ring cover 6 made of a two-color material not only does not affect the use requirements of the side-emitting, but also can improve the aesthetics of the overall side-emitting headlight module.
