[0018] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] This disclosure provides a vehicle lighting assembly 1. (See reference...) Figure 1 The vehicle headlight assembly 1 includes a light source 10, a light guide 11, and a thick-walled component 12. The first end 111 of the light guide 11 receives light emitted from the light source 10, and the internal channel of the light guide 11 allows for total internal reflection of light to the second end 112 of the light guide 11. (Refer to...) Figure 2 The light guide 11 has light guide teeth 113 on at least a portion of its side surface, allowing a portion of the light inside the light guide 11 to exit from the side surface. A thick-walled member 12 is arranged on one side of the light guide 11 and is used to scatter the light emitted from the light guide teeth 113 (see reference). Figure 2 The middle arrow indicates the path of the emitted light.

[0022] The light source 10 can be an LED (light-emitting diode) lamp. The light guide 11 can be made of transparent plastic.

[0023] It is understood that the internal channel of the light guide 11 can extend approximately along the extension direction of the light guide 11 and can pass through the first end 111 to form a first light inlet. The first light inlet can face the light source 10 to receive the light emitted by the light source 10. After the light enters the internal channel of the light guide 11 through the first light inlet, it can undergo total internal reflection in the internal channel of the light guide 11, so that it can be directed from the first end 111 of the light guide 11 to the second end 112 of the light guide 11 within the internal channel of the light guide 11.

[0024] During the process of total internal reflection of light in the internal channel of the light guide 11 and from the first end 111 to the second end 112 of the light guide 11, when the light reaches the position of the light guide tooth 113, the condition of total internal reflection is broken, so that the light reaching the position of the light guide tooth 113 can be emitted from the side of the light guide 11, while the light that does not reach the position of the light guide tooth 113 still undergoes total internal reflection and continues to be emitted to the second end 112 of the light guide 11.

[0025] The light rays that reach the location of the light guide tooth 113 are emitted from the side of the light guide 11 and then to the thick-walled member 12. After being scattered by the thick-walled member 12, they can be emitted from the lamp cover more evenly.

[0026] In summary, by adopting the technical solution provided in this embodiment, the light source 10 is placed at the first end 111 of the light guide. The light from the light source 10 enters the internal channel of the light guide through the first end 111, forms total internal reflection, and is directed to the second end 112 of the light guide. When the light reaches the position of the light guide tooth 113, some of the light can be emitted from the side of the light guide 11 to the thick-walled member 12. After being scattered by the thick-walled member 12, it is emitted to realize the lighting of the vehicle lamp assembly 1. The cost of the vehicle lamp assembly 1 can be reduced by reducing the number of light sources 10.

[0027] In some possible implementations, refer to Figure 2 The vehicle lighting assembly 1 may also include a PCB board 16, on which the light source 10 is mounted.

[0028] The PCB board 16 provides physical support for the light source 10 and can also transmit electrical energy to the light source 10.

[0029] It is understood that since the light source 10 disposed at the first end 111 of the light guide 11 in this embodiment can be a single light source 10, the volume of the PCB board 16 can be reduced to accommodate a single light source 10, thereby reducing costs.

[0030] In some possible implementations, the headlight assembly 1 may also include a controller (not shown). The controller may be electrically connected to the light source 10 for controlling the light source 10 to turn on and off.

[0031] For example, when the controller receives a signal to turn on the light source 10, the controller can control the light source 10 to turn on, so as to illuminate the vehicle light assembly 1; when the controller receives a signal to turn off the light source 10, the controller can control the light source 10 to turn off, thereby turning off the vehicle light assembly 1.

[0032] In some possible implementations, the headlight assembly 1 is positioned at the front of the vehicle. The controller is used to control the light source 10 to turn on at a first brightness when it receives a signal to turn on the daytime running lights.

[0033] For example, when the vehicle is driving during the day, the controller receives a signal to turn on the daytime running lights. The controller controls the light source 10 to turn on at a first brightness, that is, to illuminate the headlight assembly 1 at the first brightness, so that the headlight assembly 1 can switch its function to daytime running lights.

[0034] In some possible implementations, the headlight assembly 1 is positioned at the front of the vehicle. The controller is used to control the light source 10 to turn on at a second brightness upon receiving a signal to turn on the parking lights.

[0035] The second brightness is less than the first brightness.

[0036] For example, when the vehicle is driving at night or in low light conditions, the controller receives a signal to turn on the parking lights. The controller then controls the light source 10 to turn on at a second brightness, that is, to illuminate the headlight assembly 1 at the second brightness, so that the headlight assembly 1 can switch its function to parking lights.

[0037] In some possible implementations, the headlight assembly 1 is located at the front of the vehicle. The controller is used to control the light source 10 to periodically turn on and off at a preset frequency when a turn signal is received.

[0038] For example, when the vehicle is in motion, the controller receives a signal to turn on the turn signal. The controller can control the light source 10 to periodically turn on and off at a preset frequency, that is, to periodically light up or turn off the headlight assembly 1 at a preset frequency, so that the headlight assembly 1 at the front of the vehicle can switch its function to turn signal.

[0039] In some possible implementations, the headlight assembly 1 is arranged at the front of the vehicle. The light source 10 may include a first lamp core (not shown) and a second lamp core (not shown), wherein the first lamp core emits white light and the second lamp core emits yellow light. The controller is configured to control the first lamp core to turn on and the second lamp core to turn off when receiving a signal to turn on the daytime running lights or a signal to turn on the parking lights, and is configured to control the first lamp core to turn off and the second lamp core to turn on when receiving a signal to turn on the turn lights.

[0040] Specifically, when the vehicle is driving during the day, the controller receives a signal to turn on the daytime running lights. The controller controls the first lamp core of the light source 10 to turn on at the first brightness, that is, to illuminate the headlight assembly 1 of the vehicle with white light at the first brightness, so that the headlight assembly 1 of the vehicle can switch its function to daytime running lights.

[0041] When the vehicle is driving at night or in low light conditions, the controller receives a signal to turn on the parking lights. The controller then controls the first lamp core of the light source 10 to turn on at a second brightness, that is, to illuminate the headlight assembly 1 at the second brightness with white light, so that the headlight assembly 1 can switch its function to parking lights.

[0042] When the vehicle is in motion, the controller receives a signal to turn on the turn signal. The controller can control the second lamp core of the light source 10 to periodically turn on and off at a preset frequency. That is, to periodically light up or turn off the headlight assembly 1 with yellow light at a preset frequency, so that the headlight assembly 1 at the front of the vehicle can switch its function to turn signal.

[0043] In some possible implementations, the headlight assembly 1 is located at the rear of the vehicle. The controller is used to control the light source 10 to turn on when a signal to turn on the parking lights is received.

[0044] For example, when the vehicle is driving at night or in low light conditions, the controller receives a signal to turn on the parking lights, and the controller controls the light source 10 to turn on, that is, to illuminate the taillight assembly 1, so that the taillight assembly 1 can switch its function to parking lights.

[0045] In some possible implementations, the headlight assembly 1 is located at the rear of the vehicle. The controller is used to control the light source 10 to periodically turn on and off at a preset frequency when a turn signal is received.

[0046] For example, when the vehicle is in motion, the controller receives a signal to turn on the turn signal. The controller can control the light source 10 to periodically turn on and off at a preset frequency, that is, to periodically light up or turn off the taillight assembly 1 at a preset frequency, so that the taillight assembly 1 can switch its function to turn signal.

[0047] In some possible implementations, the headlight assembly 1 is located at the rear of the vehicle. The light source 10 may include a first lamp core and a second lamp core, wherein the first lamp core emits white light and the second lamp core emits yellow light. The controller is configured to control the first lamp core to turn on and the second lamp core to turn off when receiving a signal to turn on the parking lights, and to control the first lamp core to turn off and the second lamp core to turn on when receiving a signal to turn on the turn lights.

[0048] Specifically, when the vehicle is driving at night or in low light conditions, the controller receives a signal to turn on the parking lights. The controller then controls the first lamp core of the light source 10 to turn on, which means that the taillight assembly 1 is illuminated with white light, so that the taillight assembly 1 can switch its function to parking lights.

[0049] When the vehicle is in motion, the controller receives a signal to turn on the turn signal. The controller can control the second lamp core of the light source 10 to periodically turn on and off at a preset frequency. That is, to periodically light up or turn off the taillight assembly 1 with yellow light at a preset frequency, so that the taillight assembly 1 can switch its function to turn signal.

[0050] In some possible implementations, the headlight assembly 1 is located at the rear of the vehicle. The light source 10 may include a third lamp core (not shown) that emits red light. The controller is used to control the third lamp core to turn on when a signal to turn on the brake lights is received.

[0051] For example, when the vehicle brakes, the controller receives a signal to turn on the brake lights. The controller can control the third lamp core of the light source 10 to turn on, that is, to illuminate the taillight assembly 1 with red light, so that the taillight assembly 1 can switch its function to brake lights.

[0052] In some possible implementations, the headlight assembly 1 is located at the rear of the vehicle. The light source 10 may include a first lamp core and a third lamp core, wherein the first lamp core emits white light and the third lamp core emits red light. The controller is configured to control the first lamp core to turn on and the second lamp core to turn off when receiving a signal to turn on the parking lights, and to control the first lamp core to turn off and the third lamp core to turn on when receiving a signal to turn on the brake lights.

[0053] Specifically, when the vehicle is driving at night or in low light conditions, the controller receives a signal to turn on the parking lights. The controller then controls the first lamp core of the light source 10 to turn on, which means that the taillight assembly 1 is illuminated with white light, so that the taillight assembly 1 can switch its function to parking lights.

[0054] When the vehicle brakes, the controller receives a signal to turn on the brake lights. The controller can then control the third lamp core of the light source 10 to turn on, which means that the taillight assembly 1 is illuminated with red light, so that the taillight assembly 1 can switch its function to brake lights.

[0055] In some possible implementations, the vehicle lighting assembly 1 may further include an RGB light source (not shown in the figure). The RGB light source may be located at the second end 112 of the light guide 11, and the light emitted by the RGB light source can enter the internal channel of the light guide 11 through the second end 112 of the light guide 11. The controller may be electrically connected to the RGB light source, and the controller is used to control the RGB light source to turn on and control the light source 10 to turn off when receiving a signal to turn on the exterior ambient lighting.

[0056] It is understood that the internal channel of the light guide 11 can extend approximately along the extension direction of the light guide 11 and pass through the second end 112 to form a second light inlet. The second light inlet can face the RGB light source to receive the light emitted by the RGB light source. After the light enters the internal channel of the light guide 11 through the second light inlet, it can undergo total internal reflection in the internal channel of the light guide 11, so that it can be directed from the second end 112 of the light guide 11 to the first end 111 of the light guide 11 within the internal channel of the light guide 11.

[0057] During the process of total internal reflection of light in the internal channel of the light guide 11 and from the second end 112 of the light guide 11 to the first end 111 of the light guide 11, when the light reaches the position of the light guide tooth 113, the condition of total internal reflection is broken, so that the light reaching the position of the light guide tooth 113 can be emitted from the side of the light guide 11, while the light that does not reach the position of the light guide tooth 113 still undergoes total internal reflection and continues to be emitted towards the second end 112 of the light guide 11.

[0058] The light rays that are directed to the location of the light guide tooth 113 are emitted from the side of the light guide 11 and then to the thick-walled member 12. After being scattered by the thick-walled member 12, the light rays can be emitted from the lamp cover more evenly.

[0059] For example, when a user is camping in the wild, the user can switch the function of the vehicle light component 1 to the exterior ambient light as needed, thereby expanding the scope of use of the vehicle light component 1 and increasing its entertainment value.

[0060] By setting an RGB light source at the second end 112 of the light guide tube 11, the vehicle light assembly 1 can be switched to an exterior ambient light when the user needs to turn it on, thereby expanding the range of application scenarios for the vehicle light assembly 1 and increasing its entertainment value.

[0061] In some possible implementations, refer to Figure 3 The thick-walled member 12 includes a first thick-walled portion 121 and a second thick-walled portion 122 connected to each other. The first thick-walled portion 121 and the second thick-walled portion 122 are arranged along the extension direction of the thick-walled member 12, and the width of the first thick-walled portion 121 is smaller than the width of the second thick-walled portion 122.

[0062] It should be noted that the thick-walled component 12 can be a component that is directly visible in appearance. This means that the shape of the thick-walled component 12 can affect the aesthetics of the headlight assembly 1. In related technologies, when multiple light sources 10 are used for direct or reflected light, the thick-walled component 12 receives discrete point light sources 10 with varying intensities. Therefore, it is necessary to ensure that the width of the thick-walled component 12 is consistent in its extension direction to ensure that the light scattered by the thick-walled component 12 is relatively uniform. However, the consistent width of the thick-walled component 12 in its extension direction also limits its shape, which in turn limits the aesthetics of the headlight assembly 1.

[0063] In this embodiment, light from the internal channel of the light guide 11 is emitted from the side of the light guide 11 via the light guide teeth 113, forming relatively uniform light rays that are directed toward the thick-walled member 12. It is understood that the light rays emitted from the side of the light guide 11 toward the thick-walled member 12 are relatively uniform, and the thick-walled member 12 receives a continuous surface light source 10 with approximately the same intensity. Therefore, the requirement for thickness uniformity of the thick-walled member 12 in the extending direction is relatively low. Thus, the width of the first thick-walled portion 121 can be set to be smaller than that of the second thick-walled portion 122, which can enrich the shape of the thick-walled member 12 and improve the aesthetics of the headlight assembly 1.

[0064] In some possible implementations, refer to Figure 4 The light guide tube 11 includes a first tube body 114, a second tube body 115, and a branch tube body 116. (Reference) Figure 3 and Figure 4 The first tube 114 is located on one side of the first thick-walled portion 121. The second tube 115 is located on one side of the second thick-walled portion 122, with one end of the second tube 115 connected to the first tube 114 and the second end 112 located at the end of the second tube 115 opposite to the first tube 114. The branch tube 116 is located on one side of the second thick-walled portion 122, with one end of the branch tube 116 connected to the first tube 114, and the branch tube 116 and the second tube 115 are connected in parallel. The sides of the first tube 114, the second tube 115, and the branch tube 116 are all provided with optical guide teeth 113.

[0065] The extension direction of the light guide 11 can be approximately the same as the extension direction of the thick-walled member 12.

[0066] When light from the inner channel of the light guide 11 enters the first tube 114, a portion of the light reaches the location of the light guide teeth 113 on the side of the first tube 114, breaking the total internal reflection condition. This allows the light to exit from the side of the first tube 114 and reach the first thick-walled portion 121, while a second portion of the light continues to undergo total internal reflection. A portion of the second portion of the light then undergoes total internal reflection into the second tube 115. When at least a portion of the light reaches the location of the light guide teeth 113 on the side of the second tube 115, the total internal reflection condition is broken, allowing the light to exit from the side of the second tube 115 and reach the second thick-walled portion 122. Furthermore, the remaining portion of the second portion of the light undergoes total internal reflection into the branch tube 116. When at least a portion of the light reaches the location of the light guide teeth 113 on the side of the branch tube 116, the total internal reflection condition is broken, allowing the light to exit from the side of the branch tube 116 and reach the second thick-walled portion 122.

[0067] In this embodiment, the first thick-walled portion 121 corresponds to the first tube 114, and the second thick-walled portion 122 corresponds to the second tube 115 and the branch tube 116. When the width of the second thick-walled portion 122 is greater than the width of the first thick-walled portion 121, by adding a branch tube 116 connected in parallel with the second tube 115, the brightness of the light emitted by the second thick-walled portion 122 can be approximately the same as the brightness of the light emitted by the first thick-walled portion 121.

[0068] In some possible embodiments, the light guide 11 includes a first tube body 114 and a second tube body 115. The first tube body 114 is located on one side of the first thick-walled portion 121. The second tube body 115 is located on one side of the second thick-walled portion 122, with one end of the second tube body 115 connected to the first tube body 114, and a second end 112 located at the end of the second tube body 115 opposite to the first tube body 114. The diameter of the second tube body 115 is larger than the diameter of the first tube body 114.

[0069] When light from the inner channel of the light guide 11 enters the first tube 114, a portion of the light reaches the location of the light guide teeth 113 on the side of the first tube 114, and the total internal reflection condition is broken, allowing the light to exit from the side of the first tube 114 and reach the first thick-walled portion 121. A second portion of the light then undergoes total internal reflection. This second portion of the light continues to undergo total internal reflection into the second tube 115. When at least a portion of the light reaches the location of the light guide teeth 113 on the side of the second tube 115, the total internal reflection condition is broken, allowing the light to exit from the side of the second tube 115 and reach the second thick-walled portion 122.

[0070] The first thick-walled portion 121 corresponds to the first tube 114, and the second thick-walled portion 122 corresponds to the second tube 115. By setting the diameter of the second tube 115 to be larger than the diameter of the first tube 114, the brightness of the light emitted from the second thick-walled portion 122 can be made to be approximately the same as the brightness of the light emitted from the first thick-walled portion 121.

[0071] In some possible implementations, refer to Figure 4 The light guide tube 11 also includes a third tube body 117. One end of the third tube body 117 is connected to the end of the first tube body 114 opposite to the second tube body 115, and the first end 111 is located at the end of the third tube body 117 opposite to the second tube body 115.

[0072] It should be noted that the side of the third tube 117 does not have light guide teeth 113, so the light is totally reflected inside the third tube 117.

[0073] Specifically, the light from the light source 10 enters the third tube 117 from the first end 111, undergoes total internal reflection within the third tube 117, and then travels into the first tube 114. When a portion of the light in the first tube 114 reaches the location of the light guide tooth 113 on the side of the first tube 114, the total internal reflection condition is broken, allowing the light to exit from the side of the first tube 114 and travel into the first thick-walled portion 121. The remaining portion of the light in the first tube 114 undergoes total internal reflection into the second tube 115. When at least a portion of the light in the second tube 115 reaches the location of the light guide tooth 113 on the side of the second tube 115, the total internal reflection condition is broken, allowing the light to exit from the side of the second tube 115 and travel into the second thick-walled portion 122.

[0074] In some possible implementations, refer to Figure 1 The headlight assembly 1 also includes a light shield 13, which is arranged on one side of the first tube 114.

[0075] The light shield 13 can block the first tube 114, preventing stray light from entering the first tube 114.

[0076] In some possible implementations, refer to Figure 5 The thick-walled component 12 has a first surface 123. The first surface 123 faces the light guide 11, and the first surface 123 is provided with a first scattering pattern (not shown in the figure).

[0077] The light emitted from the light guide teeth 113 on the side of the light guide 11 is directed to the first surface 123 of the thick-walled member 12, and the light is scattered by the first scattering pattern set on the first surface 123.

[0078] In some possible implementations, refer to Figure 5 The thick-walled member 12 has a second surface 124. The second surface 124 is located on the side of the thick-walled member 12 away from the first surface 123, and the second surface 124 is provided with a second scattering pattern (not shown in the figure).

[0079] The light emitted from the light guide teeth 113 on the side of the light guide 11 is directed to the first surface 123 of the thick-walled member 12. The first scattering pattern on the first surface 123 can scatter the light for the first time. The light scattered by the first surface 123 is directed to the second surface 124 of the thick-walled member 12. The second scattering pattern on the second surface 124 can scatter the light for the second time and then emit it.

[0080] The light emitted from the light guide teeth 113 on the side of the light guide 11 is scattered twice by the first scattering pattern and the second scattering pattern, which can further ensure the uniformity of the light emitted through the thick-walled part 12.

[0081] In some possible implementations, refer to Figure 1 The headlight assembly 1 also includes a bracket 14. The bracket 14 is connected to the light guide tube 11.

[0082] The bracket 14 provides mechanical support for the light guide 11 to fix the light guide 11 and prevent the relative position of the light guide 11 and the thick-walled member 12 from changing.

[0083] In some possible implementations, refer to Figure 1 The headlight assembly 1 also includes a trim piece 15. The trim piece 15 surrounds the sides of the thick-walled member 12.

[0084] The decorative part 15 can be combined with the shape of the thick-walled part 12 to further enhance the aesthetics of the headlight assembly 1.

[0085] This disclosure also provides a vehicle including the aforementioned headlight assembly 1.

[0086] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0087] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this disclosure. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0088] In the description of this disclosure, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this disclosure and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this disclosure; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0089] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0090] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this disclosure.

[0091] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
