[0035] The utility model provides a vehicle lamp lighting device and a vehicle, aiming to solve the problems of high manufacturing cost and great processing difficulty existing in the prior art.
[0036] As described in the background technology, the existing headlight lighting device mainly adopts a thick-walled structure made of resin material. The thick-walled structure can convert the light emitted by the light source into parallel light and fully diffuse the light, so that the headlight lighting device can emit light evenly and ensure the lighting effect. However, compared with the traditional resin molding structure, the thickness of the thick-walled structure is much greater than that of the traditional resin molding structure, which will lead to an increase in the manufacturing cost and processing difficulty of the thick-walled structure, which will lead to the problem of high manufacturing cost and great processing difficulty in the headlight lighting device.
[0037] The embodiment of the utility model provides a vehicle lamp lighting device, such as Figure 1 and Figure 2 As shown, the vehicle lamp lighting device includes a circuit board 100, a first light guide block 200 and a second light guide block 300, the circuit board 100 is provided with a light source 110; the first light guide block 200 is covered on the light source 110, and the first light guide block 200 is used to convert the light emitted by the light source 110 into parallel light; the second light guide block 300 includes a bottom plate 310, a first side plate 320 and a second side plate 330 arranged at intervals, the first side plate 320 is located on a side of the first light guide block 200 away from the circuit board 100, the second side plate 330 is located on a side of the first side plate 320 away from the first light guide block 200, the two sides of the bottom plate 310 are respectively connected to the first side plate 320 and the second side plate 330, the bottom plate 310, the first side plate 320 and the second side plate 330 are integrally formed, and the bottom plate 310, the first side plate 320 and the second side plate 330 are surrounded to form a light-passing space 311 for parallel light to pass through.
[0038] Specifically, the first light guide block 200 covering the light source 110 can convert the light emitted by the light source 110 into parallel light. The light-passing space 311 formed by the bottom plate 310, the first side plate 320 and the second side plate 330 can fully diffuse the parallel light when the parallel light passes through, so that the vehicle lamp light-emitting device can emit light evenly and ensure the lighting effect. The light-passing space 311 formed by the bottom plate 310, the first side plate 320 and the second side plate 330 can also attenuate the parallel light when the parallel light passes through, which can effectively reduce the strong light emitted by the light source 110 to avoid the generation of bright spots. The vehicle lamp lighting device is configured by sequentially arranging a first light guide block 200 and a second light guide block 300 on one side of a light source 110, and the first light guide block 200 converts the light emitted by the light source 110 into parallel light, and the second light guide block 300 fully diffuses the parallel light, which enables the vehicle lamp lighting device to emit light uniformly and ensures a lighting effect; and the first light guide block 200 realizes the conversion of the light emitted by the light source 110 into parallel light, and the second light guide block 300 realizes the diffusion of the parallel light, so that the first light guide block 200 and the second light guide block 300 can both be made of a traditional resin molding structure, which can reduce the production cost and processing difficulty of the vehicle lamp lighting device.
[0039] In one embodiment, if Figure 2 and Figure 3 As shown, the first light guide block 200 is provided with an optical pattern 210 at the position corresponding to the light source 110, and the optical pattern 210 is used to convert the light emitted by the light source 110 into parallel light. Specifically, the light emitted by the light source 110 is converted into parallel light by the optical pattern 210, which makes it only necessary to provide the optical pattern 210 at the position corresponding to the light source 110 of the first light guide block 200, which can reduce the difficulty of manufacturing the first light guide block 200.
[0040] In a specific embodiment, Figure 4 and Figure 5As shown, the optical pattern 210 includes a plurality of protrusions 211 arranged in sequence from the inside to the outside, and each of the plurality of protrusions 211 has a refractive surface 212, and each refractive surface 212 is inclined from the inside to the outside from the side close to the first side plate 320 to the side away from the first side plate 320; the angle between the refractive surface 212 on the protrusion 211 located on the inside and the first side plate 320 is recorded as a first inclination angle α, and the angle between the refractive surface 212 on the protrusion 211 located on the outside and the first side plate 320 is recorded as a second inclination angle β, wherein α<β. Specifically, the refractive surface 212 is inclined from the side close to the second light guide block 300 to the side away from the second light guide block 300 from the inside to the outside, and can refract the light when the light passes through the refractive surface 212, so that the light passes through the second light guide block 300 in a direction perpendicular to the first side plate 320, and the first inclination angle α is smaller than the second inclination angle β, which can make the light converted by the optical pattern 210 pass through the second light guide block 300 in a direction perpendicular to the first side plate 320. It should be noted that the angle between the light from the light source 110 that enters the inner protrusion 211 and the horizontal plane is smaller than the angle between the light from the light source 110 that enters the outer protrusion 211 and the horizontal plane, and when the light is emitted from the refractive surface 212, the protrusion 211 located on the outside needs to refract the light at a larger angle to ensure that the light passes through the second light guide block 300 in a direction perpendicular to the first side plate; it should be noted that when processing and manufacturing the optical pattern 210, different numbers of protrusions 211 can be processed according to actual needs.
[0041] In a more specific embodiment, Figures 3 to 5 As shown, the first light guide block 200 is provided with an end surface 220 on one side close to the first side plate 320, each protrusion 211 is provided on the end surface 220, and the end surface 220 is formed with an abutting portion 221, and the distance between the top of the abutting portion 221 and the end surface 220 is greater than the distance between the top of any protrusion 211 and the end surface 220. Specifically, the distance between the top of the abutting portion 221 and the end surface 220 is greater than the distance between the top of any protrusion 211 and the end surface 220, which can prevent the first side plate 320 from colliding with any protrusion 211 when being installed on one side of the first light guide block 200, thereby avoiding damage.

[0043] In one embodiment, if Figure 6 As shown, the vehicle lamp lighting device further includes a fixing screw 400, the first side plate 320 forms a mounting seat 321, one end of the mounting seat 321 away from the first side plate 320 passes through the first light guide block 200 and abuts against the circuit board 100, the circuit board 100 is provided with a mounting hole 120, the fixing screw 400 passes through the mounting hole 120 and is connected to the mounting seat 321. Specifically, the assembly of the vehicle lamp lighting device can be completed by passing the fixing screw 400 through the mounting hole 120 and connecting it to the mounting seat 321, and the assembly process is simple and convenient.
[0044] In a specific embodiment, Figure 2 and Figure 6 As shown, the mounting seat 321 is provided with a threaded hole 322, and one end of the fixing screw 400 passes through the mounting hole 120 and is threadedly connected to the threaded hole 322. Specifically, the mounting seat 321 is provided with a threaded hole 322, and when assembling the vehicle lamp lighting device, it is only necessary to pass the fixing screw 400 through the mounting hole 120 and be threadedly connected to the threaded hole 322, and it is not necessary to use a nut matched with the fixing screw 400 for fixing, which can further reduce the difficulty of assembling the vehicle lamp lighting device.
[0045] In one embodiment, if Figure 2 and Figure 3 As shown, the circuit board 100 is provided with a positioning hole 130, and the first light guide block 200 is provided with a positioning post 230, and the positioning post 230 is passed through the positioning hole 130.
