The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0024] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly.

[0030] In this application, "multiple" means two or more (including two).

[0031] Light guides can be used to reflect the light emitted by the light source of a lamp assembly (such as LED beads) and emit light themselves to achieve lighting or warning functions.

[0032] However, the light guide strip needs to be fixed on the bracket, which is fixed on the lamp housing and then installed on the vehicle body through the lamp housing. The connection structure between the light guide strip and the bracket will affect the light reflection and refraction of the light guide strip itself, causing refraction and light spots to form in the area where the connection structure is set, which will affect the user experience.

[0033] Specifically, such as Figure 1As shown in the prior art, the connection area between the connecting structure and the light guide strip body is constructed with an obtuse angle transition. This causes the light inside the light guide strip to break its original regular path after total internal reflection on the inclined surface, resulting in multiple light rays overlapping and ultimately producing a bright spot. That is, during the light reflection process, some light rays will hit the inclined surface between the connecting structure and the light guide strip body. The light rays on this inclined surface will be further reflected and refracted, which will cause multiple light rays to overlap and form a bright spot on the visible surface of the light guide strip, affecting the user experience.

[0034] Based on this, this application proposes a light guide strip, wherein the light guide strip and the connecting part can be constructed as a right-angle transition, that is, the connecting part and the light guide strip body form a 90° angle to form a right-angle transition. The right-angle transition can reduce the influence of light reflection between the connecting structure and the light guide strip body. Parallel light is incident on the light guide strip, and after total internal reflection, parallel light can still be uniformly displayed, which can reduce the probability of light overlap, thereby improving or even eliminating bright spot phenomenon, making the light emission of the light guide strip more uniform, thereby improving the light emission effect and decorative effect of the light guide strip, and improving the user experience.

[0035] The following is for reference. Figures 2-3 This application describes a light guide strip 10, a lamp assembly 100, and a vehicle according to embodiments thereof.

[0036] like Figure 3 As shown, in a first aspect, this application provides a light guide strip 10, including: a light guide strip body 11 and a connecting portion 12, wherein the connecting portion 12 is located on any side surface of the light guide strip body 11.

[0037] Specifically, the light guide strip body 11 may have two end faces and multiple side faces. At least one of the multiple side faces may be formed as a visible surface to emit light through the visible surface, thereby achieving the luminous effect and decorative effect of the light guide strip 10. The luminous effect may be used for warning purposes or for ambient display, etc. This application does not make any specific limitations.

[0038] Furthermore, both the light guide strip body 11 and the connecting part 12 are constructed of transparent material, and the angle between the connecting part 12 and the light guide strip body 11 at least one end is 90°.

[0039] The light guide strip body 11 and the connecting part 12 are integrally formed. Both the light guide strip body 11 and the connecting part 12 can be constructed of transparent material so that when parallel light is incident on the light guide strip body 11, it can undergo total internal reflection within the light guide strip body 11. Furthermore, when the light reflected inside the light guide strip body 11 passes through the connecting part 12, which is at a 90° angle to the light guide strip body 11, most of the parallel light can maintain its original regular path (see...). Figure 2This allows the reflection angle of most parallel light rays to remain unchanged, thereby reducing the probability of light ray overlap after parallel light is incident, improving the bright spot phenomenon, and making the parallel light appear uniformly.

[0040] For example, the transparent material can be a polymer material, such as polymethyl methacrylate (PMMA), polycarbonate (PC), etc.

[0041] According to the embodiments of this application, the light guide strip 10, by constructing the light guide strip body 11 and the connecting part 12 as a right-angle transition, can reduce the influence of the connecting part 12 on the parallel light reflection path, so that more parallel light can maintain the original regular path, thereby achieving uniform light emission of the light guide strip 10, improving the light spot phenomenon, and enhancing the user experience.

[0042] like Figure 3 As shown, according to some embodiments of this application, the connecting part 12 includes a connecting section 121 and a mounting section 122. The connecting section 121 is connected to the light guide strip body 11, and the mounting section 122 is located at the end of the connecting section 121 away from the light guide strip body 11. The angle between the extension direction of the connecting section 121 and the extension direction of the light guide strip body 11 is 90°.

[0043] Specifically, the connecting portion 12 may include a connecting section 121 and a mounting section 122, both of which may be constructed as plate-like structures (see [reference]). Figure 3 One end of the connecting segment 121 is connected to one side of the light guide strip body 11, and the other end of the connecting segment 121 is connected to the mounting segment 122, which is spaced apart from the light guide strip body 11 to form a clamping space between the mounting segment 122 and the light guide strip body 11. The mounting segment 122 can be used to fix the light guide strip 10, reducing the difficulty of fixing and assembling the light guide strip 10. The extension direction of the connecting segment 121 is at a 90-degree angle to the extension direction of the light guide strip body 11, and the connection segment 121 and the light guide strip body 11 are constructed with a right-angle transition to avoid the connection segment 121 causing the reflection law path of parallel light to be disrupted, thus achieving the above-mentioned technical effect.

[0044] According to some embodiments of this application, there is an arc transition between the mounting section 122 and the connecting section 121.

[0045] Specifically, the connecting section 121 is constructed as a rectangular plate, the mounting section 122 is located on one side of the connecting section 121, and the area where the mounting section 122 is connected to the connecting section 121 has a side surface facing the light guide strip body 11 and a side surface away from the light guide strip body 11. The side surface away from the light guide strip body 11 is constructed as a plane, and the side surface facing the light guide strip body 11 is constructed as an arc transition surface.

[0046] In this way, the reflective surface of the adjacent connecting section 121 is constructed as a plane, and this area is also constructed as a plane, which can further ensure the uniform display of parallel light. The surface of the side facing the guide light strip body 11 is constructed as an arc transition surface, which can reduce the number of sharp edges during the connection between the mounting section 122 and the surrounding components, improve scratches, reduce scratches on the appearance surface of the surrounding components during the assembly process, and increase the contact area between the mounting section 122 and the surrounding components, thereby improving installation stability and reliability.

[0047] According to some embodiments of this application, the angle formed by the extending directions of the mounting section 122 and the connecting section 121 is a right angle.

[0048] Thus, the mounting section 122 and the connecting section 121 can define an L-shaped mounting structure. After assembly, the mounting section 122 and the connecting section 121 can be located on the back side or adjacent side of the visible surface of the light guide strip body 11. After assembly, the mounting section 122 and the connecting section 121 can be covered by the light guide strip body 11 to further improve aesthetics.

[0049] According to some embodiments of this application, the light guide strip 10 has at least two connecting portions 12 along its own length direction, and the multiple connecting portions 12 are arranged at intervals.

[0050] In other words, there can be multiple connecting parts 12, and the multiple connecting parts 12 are arranged at intervals along the length of the light guide strip body 11, so that the light guide strip 10 can be installed and fixed through the multiple connecting parts 12, which can improve the fixing stability and reliability.

[0051] Meanwhile, the arrangement of multiple connecting parts 12 can improve the stress on the light guide strip 10, making the stress distribution of the light guide strip body 11 in the length direction more uniform, reducing the probability of the light guide strip 10 locally lifting or falling off, and further improving the aesthetics of the light guide strip 10.

[0052] like Figure 3 As shown, in a second aspect, this application provides a lamp assembly 100, including: a light guide strip 10, a light emitter, a mounting bracket 20, and a lamp housing (not shown in the figure). The light emitter is located at at least one end of the light guide strip 10 and is adapted to excite the light guide strip 10 to emit light. The mounting bracket 20 is connected to the connecting portion 12 and is connected to the lamp housing. The lamp housing is adapted to be fixed to the vehicle body.

[0053] Specifically, the light-emitting body can be constructed as an LED lamp bead. The light-emitting body can be set at one end of the length of the light guide strip body 11, or LED lamp beads can be set at both ends of the length of the light guide strip body 11, so as to emit parallel light through the light-emitting body and make the parallel light totally internally reflected in the light guide strip 10 in the above embodiment, so as to achieve uniform light emission of the light guide strip 10.

[0054] The mounting bracket 20 is used to fix the light guide strip 10 and the light emitter, and to position the light emitter at the long end of the light guide strip 10. The light guide strip 10 is connected to the mounting bracket 20 through the connecting part 12. The arrangement of multiple connecting parts 12 can improve the fixing stability and reliability of the light guide strip 10 on the mounting bracket 20. The mounting bracket 20 is further fixed to the lamp housing, and the lamp housing is fixed to the vehicle body to realize the fixing of the lamp assembly 100 on the vehicle body.

[0055] According to the embodiment of this application, the light-emitting body and the light guide strip 10 of the lamp assembly 100 are both fixed on the mounting bracket 20. The mounting bracket 20 is further used to connect with the vehicle body, which can reduce the assembly difficulty of the lamp assembly 100 on the vehicle body. At the same time, by using the light guide strip 10, the light emission effect of the lamp assembly 100 can be better, effectively eliminating light spot defects and improving the user experience.

[0056] exist Figure 3 In the embodiments shown, according to some embodiments of this application, the mounting bracket 20 at least partially covers the light guide strip 10 and has a mounting groove 21 for accommodating the connecting portion 12.

[0057] Specifically, the receiving groove includes a first receiving portion 211 and a second receiving portion 212. The first receiving portion 211 is adapted to receive the mounting section 122 of the connecting portion 12, and the second receiving portion 212 is adapted to receive the connecting section 121 of the connecting portion 12. At least the first receiving portion 211 is fastened to the mounting section 122.

[0058] In other words, the mounting bracket 20 can at least partially cover the light guide strip 10, allowing the light guide strip 10 to be exposed only on the visible surface where uniform light emission is displayed, which can further enhance the refined appearance of the lamp assembly 100. The mounting groove 21 is used to accommodate the connecting part 12, such as the first accommodating part 211 accommodating the mounting section 122 and the second accommodating part 212 accommodating the connecting section 121. Under the premise of fixing the light guide strip 10 with the mounting bracket 20, the gap between the mounting bracket 20 and the light guide strip 10 can be reduced to further improve the aesthetics.

[0059] Thirdly, this application provides a vehicle including: the lamp assembly 100 in the above embodiments, which has the same technical effects as the lamp assembly 100, and will not be described again here.

[0060] It is understandable that the lamp assembly 100 is constructed as at least one of a high-mounted brake light and a continuous taillight.

[0061] In this way, the light-emitting elements located at both ends of the length of the light guide strip 10 can be used to stimulate the light guide strip 10 to emit light evenly. The light guide strip 10 can be used as a light strip for a high-mounted brake light or a light strip for a through-type taillight, which can improve the display effect of the high-mounted brake light or the through-type taillight and enhance its aesthetics.

[0062] The light guide strip 10, the lamp assembly 100, and other components and operations of the vehicle according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

[0063] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.
