[0036] In the related art, the car lamp usually uses a light guide bar and a thick wall part 300 to complete light guiding and light emitting under the combination of an auxiliary support, so as to realize the illumination light energy of the car lamp. However, in such a structure, it is often accompanied by the problems of large space occupation, high cost and large installation difficulty caused by too many components. The light guide bar is usually provided with an entrance light part, and the light reflection and refraction energy inside the light guide bar gradually decreases along with the length of the light guide bar, resulting in that the whole light guide bar gradually changes from bright to dark.

[0037] Therefore, some embodiments of the present application propose a car lamp assembly, which is specifically shown in the Figures 1-5 .

[0038] Referring to Figure 1As shown in the embodiment of the utility model, the vehicle lamp assembly can include: a light guide strip, a light tooth 200 and a thick wall piece 300, the light guide strip includes an upper light guide 103, a lower light guide 101 and a linking part 102, the upper light guide 103 and the lower light guide 101 are seamlessly connected through the linking part 102; the left and right ends of the lower light guide 101 are respectively provided with light inlet parts, that is, there are two light inlet parts, the light inlet parts at the left and right ends of the lower light guide 101 are provided with light sources, the light sources simultaneously shoot light through the light inlet parts at the left and right ends of the lower light guide 101, so that the lower light guide 101 obtains uniform and stable light; the light tooth 200 is arranged on one side of the upper light guide 103, the light tooth 200 will cause refraction and scattering of the optical fiber, change the propagation direction of the light, and make the light more uniformly shoot to the thick wall piece 300 according to the design requirement; the thick wall piece 300 and the upper light guide 103 are seamlessly connected, and it can be understood that the thick wall piece 300 and the light guide strip are integrally formed by using the same material through a mold, that is, the thick wall piece 300, the upper light guide 103, the lower light guide 101 and the linking part 102 are integrally formed by using the same material through a mold.

[0039] It should be noted that the light source can be an LED lamp bead, can also be a halogen lamp, and can also be other types of light emitting devices, which can be selected and arranged according to actual conditions by those skilled in the art, and the present embodiment does not limit this.

[0040] Specifically, taking the LED lamp bead as an example, two light sources are turned on and emit light, which first shoots to the light inlet surface arranged at the left and right ends of the lower light guide 101. It can be understood that since the light emitted by the LED lamp bead has a certain divergence, the light inlet surface of the lower light guide 101 will collect these light as much as possible to reduce light loss according to optical design. After the light enters the lower light guide 101, the total reflection principle inside the lower light guide 101 is used to conduct inside the lower light guide 101. The lower light guide 101 will transmit the light along the predetermined path to ensure the transmission of the light to the linking part 102.

[0041] The linking part 102 plays a key role in connection and transition. The linking part 102 receives light from the lower light guide 101 and smoothly transmits the light to the upper light guide 103. In this process, the linking part 102 fine-tunes the propagation direction or distribution direction of the light to ensure that the light enters the upper light guide 103 at a suitable angle and in a suitable manner, realizing seamless connection of the light between different components.

[0042] After the upper light guide 103 receives the light, it continues to conduct, and at the same time, the light tooth 200 on the upper light guide 103 begins to play a role. The light tooth 200 will cause refraction and scattering of the light, on the one hand, change the propagation direction of the light, and on the other hand, adjust the angle of the light, so that the light can shoot to the thick wall piece 300 according to the design requirement.

[0043] After the light reaches the thick-walled piece 300, the thick-walled piece 300 further conducts, reflects and emits the light through the internal optical structure. Finally, the light is emitted from the light-emitting surface of the thick-walled piece 300 to form a specific light shape and lighting effect, which provides lighting, signal indication or aesthetic effect for vehicle driving. The internal optical structure of the thick-walled piece 300 includes a mirror or a refractive prism.

[0044] In the conventional technology, in addition to fixing the light guide strip and the thick-walled piece 300 by the auxiliary support, buckle connection, glue bonding, ultrasonic welding or hot riveting connection and the like are used to tightly adhere the light guide strip to the thick-walled piece 300, so as to ensure that the light can be smoothly transmitted from the light guide strip to the thick-walled piece 300. However, in these methods, the auxiliary support occupies a large installation space, and for the buckle connection, glue bonding, ultrasonic welding or hot riveting connection and the like, a higher installation process and more installation time are often required to ensure that the light guide strip and the thick-walled piece 300 can be tightly adhered to ensure the smooth transmission of light. Therefore, the light guide strip and the thick-walled piece 300 are integrally formed by using the same material through a mold, so that the light guide strip and the thick-walled piece 300 do not need to be connected by an additional auxiliary support, which reduces the unnecessary occupation of space and the cost of the auxiliary support, and also eliminates the risk of light loss caused by higher installation process and improper installation, better achieves the purpose of light transmission, and improves the light-emitting effect of the thick-walled piece 300.

[0045] Referring to Figure 2 In the embodiment of the present application, the light tooth 200 and the thick-walled piece 300 are arranged on the left and right sides of the light guide 103, respectively. Specifically, in order to make the light enter the thick-walled piece 300 at a suitable angle and path, the connecting surfaces of the light tooth 200 and the thick-walled piece 300 need to maintain a specific relative position. Generally, the light tooth 200 is directly opposite the connecting surface of the thick-walled piece 300. The connecting surface of the thick-walled piece 300 refers to the surface of the thick-walled piece 300 connected to the light guide 103. The connection between the thick-walled piece 300 and the light guide 103 is integrally formed and seamlessly connected. The light tooth 200 refracts and scatters the light in the light guide 103 to the thick-walled piece 300. In order to ensure the effective propagation of light and avoid light interference, the length of the connecting surface of the thick-walled piece 300 connected to the light guide 103 is equal to the length of the light tooth 200.

[0046] Referring to Figure 3As shown, in the embodiment of the utility model, the upper and lower surfaces 301 of the thick-walled part are provided with bite patterns or patterns through the die bite process, when the light propagates to the upper and lower surfaces 301 of the thick-walled part, it produces diffuse reflection and scattering, so that the light propagation direction is more diverse, thereby making the light of the vehicle lamp more uniform and soft, effectively avoiding the phenomenon of uneven brightness or spotlight, improving the lighting effect and visual comfort, and increasing the roughness and friction of the outer surface of the thick-walled part 300, when assembled with other components, it can better engage and fix, prevent relative sliding between components, and also add unique texture and style to the appearance of the thick-walled part 300, make the vehicle lamp more three-dimensional and textured, meet the personalized needs of automobile appearance design, and increase the visual sense of lighting and non-lighting.

[0047] Referring to Figure 4 and Figure 5 As shown, Figure 4 is a prior art vehicle lamp assembly and indicator lamp 500 position relationship schematic diagram, the left dashed box is a light bar lamp group, and the right dashed box is an indicator lamp group, in the left light bar lamp group, the light bar 100 is provided with a light source 600 on one side, in the vehicle lamp assembly assembly process, in order to make the vehicle lamp beautiful, a light shielding area 400 is added in front of the light source 600 of the vehicle lamp to shield the light source 600, the size of the light shielding area 400 directly affects the distance between the indicator lamp 500 in the indicator lamp group, the greater the distance, the more the overall visual effect of the vehicle appears not enough compact and coordinated, and a certain space is wasted, which is not conducive to the efficient use of the vehicle tail space. Figure 5 is a vehicle lamp assembly embodiment and indicator lamp 500 position relationship schematic diagram of the utility model, the left dashed box is the vehicle lamp assembly of the embodiment of the utility model, and the right dashed box is an indicator lamp group, in the vehicle lamp assembly in the left dashed box, the length of the upper light guide 103 of the light bar 100 is greater than the length of the lower light guide 101, so that the total length of the lower light guide 101 after adding the light source 600 is equal to or less than the upper light guide 103, and the indicator lamp 500 in the indicator lamp group in the right dashed box is flush with the upper light guide 103, since the light source 600 is not added at the upper light guide 103, therefore, the distance between the indicator lamp 500 and the upper light guide 103, that is, the light shielding area 400, can be effectively reduced, and the distance between the light groups can also be observed to be effectively reduced through the distance indicated by the arrows in Figure 4 and Figure 5 The light layout of the vehicle is more compact and exquisite, the overall visual impact and beauty are enhanced, the indicator lamp 500 and the light emitting surface of the upper light guide 103 or the thick-walled part 300 form a more compact whole in vision, and therefore the vehicle tail space can be effectively utilized.

[0048] In the embodiment of the utility model, the length of the upper light guide can be designed according to requirements, and according to the current vehicle lamp market demand, the preferred length is 1200mm.

[0049] In the embodiment of the utility model, the height range of the thick-walled part side surface 302 includes greater than or equal to 2 cm and less than or equal to 8 cm. It can be understood that when the height of the thick-walled part side surface 302 is in the range of 2 cm to 8 cm, it can not only ensure sufficient thickness to support structural stability, achieve good optical effect and heat dissipation, but also cannot be too thick to cause problems such as weight increase and large space occupation. Among them, the height of the thick-walled part side surface 302 can also be understood as the thickness of the thick-walled part 300.

[0050] In the embodiment of the utility model, the light-emitting surface of the thick-walled part 300 is provided with a plurality of granular protrusions 700 uniformly distributed. The protrusions 700 change the light propagation path, causing light scattering and refraction. When the light is directed at the protrusions 700, it will disperse in different directions, avoiding the concentration of light in a specific area, making the overall light emission more uniform, and the reasonably distributed protrusions 700 also reduce the reflection loss of light inside the thick-walled part 300. And by changing the light distribution, the protrusions 700 create a unique visual experience, making the light appear sparkling and lively, increasing the interest and appeal, while improving the three-dimensionality of the thick-walled part 300 and the product aesthetics.

[0051] In the embodiment of the utility model, the vehicle lamp assembly includes a light guide strip and a thick-walled part 300 and can be integrally formed and seamlessly connected. Specifically, the vehicle lamp assembly can be made of synthetic resin injection molding, which not only improves the strength and integrity of the vehicle lamp assembly, but also improves the processing efficiency of the vehicle lamp assembly. More specifically, the synthetic resin includes polymethyl methacrylate or polycarbonate.

[0052] The embodiment of the utility model also proposes a vehicle lamp, which includes the vehicle lamp assembly of the above-mentioned embodiment, and the light source is arranged on the left and right sides of the lower light guide 101 to emit light to the light-in part.

[0053] The vehicle lamp of the embodiment of the utility model adopts the vehicle lamp assembly of the above-mentioned embodiment. The vehicle lamp introduces light into the lower light guide 101 through the light-in part arranged at the left and right ends of the lower light guide 101, and introduces light into the upper light guide 103 through the linking part 102; under the action of refraction and reflection of the light tooth 200, the light is introduced from the upper light guide 103 into the thick-walled part 300 which is seamlessly connected with the upper light guide 103, and the light is transmitted to the light-emitting surface through fiber refraction and reflection inside the thick-walled part 300. Through the seamless connection and integral molding of the thick-walled part 300 and the light guide strip, the auxiliary support components in the traditional technology are omitted, the cost is reduced and the installation is convenient, and the omission of the auxiliary support also saves the space occupation of the vehicle lamp assembly. The light-in part arranged on the left and right sides of the lower light guide 101 ensures stable transmission of light in the lower light guide 101, avoids the drawback that the light gradually becomes dark caused by a single light source in the traditional technology, and further improves the smoothness of the light emission of the light guide strip and the light emission effect of the vehicle lamp.

[0054] Since the vehicle lamp adopts all the technical solutions of the vehicle lamp assembly of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

Specifically, the vehicle can be a private car, such as a sedan, SUV, MPV or pickup truck, etc. The vehicle can also be an operating vehicle, such as a van, bus, small truck or large trailer, etc. The vehicle can be a gasoline car or a new energy car. When the vehicle is a new energy car, it can be a hybrid car or a pure electric car.

[0056] The vehicle of the embodiment of the utility model adopts the vehicle lamp of the above-mentioned embodiment. The vehicle introduces light into the lower light guide 101 through the light inlet part arranged at the left and right ends of the lower light guide 101, and introduces light into the upper light guide 103 through the linking part 102. Under the action of refraction and reflection of the light tooth 200, the light is introduced from the upper light guide 103 into the thick-walled part 300 which is seamlessly connected with the upper light guide 103, and the light is transmitted to the light-emitting surface through refraction and reflection of the optical fiber inside the thick-walled part 300. The seamless connection and integral molding of the thick-walled part 300 and the light guide strip saves the auxiliary support components in the traditional technology, reduces the cost and is convenient to install. Removing the auxiliary support also saves the space occupied by the vehicle lamp assembly.
