Description

Technical Field

[0001] This invention relates to the field of turn signal structure technology, and in particular to a turn signal structure and a motorcycle. Background Technology

[0002] Motorcycles, as a convenient means of transportation, greatly facilitate people's travel. Motorcycles are equipped with turn signal structures at the rear. These turn signals are located on the left and right sides of the rear of the motorcycle. They are activated when the motorcycle turns left or right to alert other vehicles or pedestrians to the turn and its direction, thereby ensuring the safe driving of the motorcycle and the safety of pedestrians.

[0003] Existing turn signal structures use multiple LEDs for direct illumination. The turn signal structure includes a lamp cover, a circuit board, and multiple LEDs. LEDs serve as the light source, and due to structural requirements, multiple LEDs are integrated onto the circuit board and spaced out. This turn signal structure offers high luminous efficiency, energy saving, low cost, ultra-long lifespan, and fast response speed.

[0004] However, the existing turn signal structure has serious graininess, poor uniformity of illumination, poor visual effect, and complicated assembly. Summary of the Invention

[0005] In view of the above, and to address the aforementioned technical problems, this application provides the following technical solution:

[0006] A turn signal structure is mounted on a motorcycle. The turn signal structure includes: a lamp housing assembly, both ends of which are mounted on the motorcycle, and a flow chamber is formed between the lamp housing assembly and the motorcycle; a thick-walled light guide assembly nested within the lamp housing assembly; a light guide strip assembly located within the lamp housing assembly, and at least a portion of the light guide strip assembly is nested within the thick-walled light guide assembly; and at least one light source assembly mounted within the lamp housing assembly. Light emitted from the light source assembly enters the light guide strip assembly, which transmits the light to the thick-walled light guide assembly, which then uniformly propagates the light out of the lamp housing assembly.

[0007] Furthermore, the lamp housing assembly includes: a lampshade, the lampshade having an opening, the thick-walled light guide assembly and the light guide strip assembly both nested inside the lampshade; and a bottom shell, the bottom shell extending into the lampshade through the opening and abutting against the outside of the light guide strip assembly, the bottom shell being fitted and connected to the light guide strip assembly and the lampshade.

[0008] Furthermore, the light guide strip assembly includes: a light guide bracket, at least a portion of which extends into the thick-walled light guide assembly; and a light guide strip, which is installed on the side of the light guide bracket away from the opening and located within the thick-walled light guide assembly; wherein a light source assembly is disposed at the end of the light guide strip, and the light emitted by the light source assembly can enter the light guide strip, and the light guide strip can transmit the light to the thick-walled light guide assembly.

[0009] Furthermore, the light guide bracket includes: a receiving groove located on the side of the light guide bracket away from the opening; wherein the light guide strip is installed in the receiving groove.

[0010] Furthermore, the thick-walled light guide assembly includes: a mounting frame, with a light guide strip extending into the mounting frame; and a thick-walled light guide, with one end of the thick-walled light guide extending into the mounting frame; wherein the light guide strip is located on the side of the thick-walled light guide closer to the opening, and the light guide strip is capable of transmitting light into the thick-walled light guide.

[0011] Furthermore, there are two light source components, which are located at opposite ends of the light guide strip.

[0012] Furthermore, the shape of the thick-walled light guide is adapted to the shape of the light guide strip so that the light guide strip can transmit light evenly into the thick-walled light guide.

[0013] Furthermore, the thickness of the thick-walled optical guide gradually decreases from the middle to the end of the thick-walled optical guide.

[0014] Furthermore, a groove structure is formed between the lampshade, the light guide strip assembly, and the base shell, and the groove structure is filled with sealant, which can connect the lampshade, the base shell, and the light guide strip assembly to each other.

[0015] This application also provides a motorcycle including the aforementioned turn signal structure.

[0016] Compared with existing technologies, the turn signal structure provided in this application features a flow chamber that conforms to aerodynamic principles, reducing wind resistance during motorcycle operation. Furthermore, the combination of the thick-walled light guide assembly and the light guide strip assembly reduces the number of light source components, simplifying the structure and improving the overall uniformity of light emission, achieving a large-area uniform light emission effect and better visual appeal. Simultaneously, the nested assembly of the lamp housing assembly, thick-walled light guide assembly, and light guide strip assembly in the same direction makes the structure more compact, saving space, facilitating assembly, and reducing time and labor costs. This also provides a foundation for uniform light emission in the turn signal structure, resulting in a stable and compact structure that facilitates light propagation. Attached Figure Description

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figure 1This application provides a motorcycle 101, which includes a turn signal structure 100. The turn signal structure 100 is mounted on the motorcycle 101 and is activated when the motorcycle 101 turns left or right, which can alert other vehicles or pedestrians to its turn and the direction of the turn, thereby ensuring the safe driving of the motorcycle 101 and the safety of pedestrians.

[0030] Existing turn signal structures use multiple LEDs for direct illumination. The structure includes a lamp cover, a circuit board, and multiple LEDs. Due to structural requirements, multiple LEDs are integrated onto the circuit board and spaced out. This type of turn signal structure offers high luminous efficiency, energy saving, low cost, extremely long lifespan, and fast response. However, in use, this existing turn signal structure suffers from severe graininess, poor illumination uniformity, unsatisfactory visual effects, and complex assembly.

[0031] Please see Figures 2 to 4 The turn signal structure 100 of this application includes a lamp housing assembly 10, a thick-walled light guide assembly 20, a light guide strip assembly 30, and at least one light source assembly 40.

[0032] Please see Figure 2 and Figure 3 The lamp housing assembly 10 is mounted on the motorcycle 101 at both ends, and the lamp housing assembly 10 and the motorcycle 101 form a flow chamber 60. The formation of the flow chamber 60 conforms to the principles of aerodynamics and can reduce the wind resistance of the motorcycle 101 during driving.

[0033] Further, please refer to Figure 4 A thick-walled light guide component 20 is nested within the lamp housing assembly 10; a light guide strip assembly 30 is located within the lamp housing assembly 10, and at least a portion of the light guide strip assembly 30 is nested within the thick-walled light guide component 20. At least one light source component 40 is installed within the lamp housing assembly 10. Light emitted from the light source component 40 enters the light guide strip assembly 30, which transmits the light to the thick-walled light guide component 20, which then uniformly propagates the light out of the lamp housing assembly 10.

[0034] In this application, by combining the thick-walled light guide component 20 with the light guide strip component 30, the number of light source components 40 can be reduced, the structure is simple, the overall light emission uniformity of the turn signal structure 100 can be improved, the effect of large-area uniform light emission can be achieved, and the visual effect is better.

[0035] Meanwhile, the nested assembly of the lamp housing assembly 10, the thick-walled light guide assembly 20, and the light guide strip assembly 30 along the same direction makes the structure more compact, saves space, and makes assembly more convenient, saving time and effort. Furthermore, it provides a foundation for the turn signal structure 100 to achieve uniform light emission, resulting in a stable and compact structure that facilitates light propagation. This avoids the serious graininess and poor uniformity of illumination problems inherent in existing structures.

[0036] Please see Figures 4 to 6 The lamp housing assembly 10 includes a lampshade 11 and a base 12. The lampshade 11 includes an opening 111, within which the thick-walled light guide assembly 20 and the light guide strip assembly 30 are nested. The base 12 extends into the lampshade 11 through the opening 111 and abuts against the outside of the light guide strip assembly 30, thus fitting together with the light guide strip assembly 30 and the lampshade 11. This nesting assembly of the lampshade 11, the thick-walled light guide assembly 20, the light guide strip assembly 30, and the base 12 in the same direction results in a more compact and stable overall structure, saves space, and facilitates installation and disassembly. Furthermore, this installation allows the thick-walled light guide assembly 20 to achieve better propagation effects and improved optical uniformity.

[0037] Meanwhile, the depth to which the thick-walled light guide assembly 20, the light guide strip assembly 30, and the bottom shell 12 extend into the lamp cover 11 is determined based on the overall shape of the turn signal structure 100. It should be noted that the depth refers to the distance from the end of the thick-walled light guide assembly 20, the light guide strip assembly 30, and the bottom shell 12 near the opening 111 to the opening 111. For example, in this embodiment, the thick-walled light guide assembly 20 is nested into the lamp cover 11 with a depth greater than or equal to 90 mm and less than or equal to 110 mm; the light guide strip assembly 30 is nested into the thick-walled light guide assembly 20 with a depth greater than or equal to 27 mm and less than or equal to 29 mm; and the bottom shell 12 is nested into the light guide strip assembly 30 with a depth greater than or equal to 6 mm and less than or equal to 8 mm. This results in a compact overall structure and saves more space.

[0038] Please continue reading. Figure 5 and Figure 6 The light guide assembly 30 includes a light guide bracket 31 and a light guide strip 32. At least a portion of the light guide bracket 31 extends into the thick-walled light guide assembly 20. The light guide strip 32 is mounted on the side of the light guide bracket 31 away from the opening 111 and is located within the thick-walled light guide assembly 20. A light source assembly 40 is located at the end of the light guide strip 32, and light emitted from the light source assembly 40 can enter the light guide strip 32, which then transmits the light to the thick-walled light guide assembly 20. The structure is simple and compact, facilitating light propagation. Simultaneously, the arrangement of the light guide strip 32 significantly reduces the number of light source assemblies 40 required, as light emitted from the end light source assembly 40 can propagate through the light guide strip 32 into the thick-walled light guide assembly 20, thereby reducing costs.

[0039] Please continue reading. Figure 4 The light guide bracket 31 includes a receiving groove 311, which is located on the side of the light guide bracket 31 away from the opening 111. The light guide strip 32 is installed in the receiving groove 311. Thus, the structure is simple and facilitates the installation and fixation of the light guide strip 32.

[0040] In this embodiment, there are two light source components 40, which are located at opposite ends of the light guide strip 32. The two light source components 40 simultaneously transmit light to the light guide strip 32, ensuring uniform light intensity within the light guide strip 32. This results in consistent light intensity transmitted to the thick-walled light guide 22, enabling the thick-walled light guide 22 to achieve a large-area uniform light emission effect, improving the overall light emission uniformity of the turn signal structure 100 and enhancing the visual effect.

[0041] Of course, in other embodiments, the number of light source components 40 can also be changed according to different needs. For example, the number of light source components 40 can be set to four, five or six, as long as the same or similar effect can be achieved.

[0042] Please see Figure 4 The thick-walled light guide assembly 20 includes a mounting frame 21 and a thick-walled light guide 22. A light guide strip 32 extends into the mounting frame 21, and one end of the thick-walled light guide 22 also extends into the mounting frame 21. The light guide strip 32 is located on the side of the thick-walled light guide 22 closest to the opening 111, and it can transmit light into the thick-walled light guide 22. Thus, the mounting frame 21 facilitates the installation and fixation of the thick-walled light guide 22, and the location of the light guide strip 32 on one side of the thick-walled light guide 22 allows for better light propagation into the thick-walled light guide 22.

[0043] In this embodiment, the shape of the thick-walled light guide 22 is adapted to the shape of the light guide strip 32, so that light can be evenly propagated from the light guide strip 32 into the thick-walled light guide 22, thereby achieving the effect of uniform light emission from the thick-walled light guide 22.

[0044] Please continue reading. Figure 4 As indicated by the arrows in the diagram, from the middle to the end of the thick-walled light guide 22, the thickness of the thick-walled light guide 22 gradually decreases. Because the light source assembly 40 is located at both ends of the light guide strip 32, the light intensity received at the end of the thick-walled light guide 22 is greater than that received at the middle. Therefore, by gradually thickening the thick-walled light guide 22 near the middle compared to the end, more light can be received and projected onto the lamp housing assembly 10, resulting in more uniform light emission from the turn signal structure 100 and a better visual effect.

[0045] Please see Figure 7 and Figure 8A groove structure 70 is formed between the lampshade 11, the light guide strip assembly 30, and the base shell 12. The groove structure 70 is filled with sealant, which connects the lampshade 11, the base shell 12, and the light guide strip assembly 30 to each other. In this way, the lamp housing assembly 10 and the light guide strip assembly 30 can be firmly connected. This method is low-cost, simple to operate, and makes the bonding more stable, thereby improving the overall structural integrity.

[0046] Please see Figure 2 The motorcycle 101 also includes a cover 50. The two ends of the turn signal structure 100 provided in this application are connected to the cover 50 of the motorcycle 101, while the remaining parts are spaced apart from the cover 50. This design facilitates the formation of a flow chamber 60 between the turn signal structure 100 and the motorcycle 101, reducing wind resistance during driving. Furthermore, it ensures that a large area of ​​the turn signal structure 100 is exposed outside the cover 50, resulting in high brightness, low cost, and high cost-effectiveness. Moreover, since most of the turn signal structure 100 is made of transparent material, it achieves a transparent and uniform light emission effect across the entire luminous area.

[0047] Please see Figure 3 The lamp housing assembly 10 also includes multiple mounting portions 13, which are located at both ends of the lamp housing assembly 10. Each mounting portion 13 can pass through a cover 50, allowing the turn signal structure 100 to be mounted on the cover 50. Thus, by connecting the mounting portions 13 to the cover 50, the entire turn signal structure 100 can be mounted on the cover 50, resulting in a simple structure, easy installation, and reduced assembly time.

[0048] In this embodiment, there are four mounting portions 13, with two mounting portions 13 at each end of the lamp housing assembly 10. This allows the lamp housing assembly 10 to be securely mounted on the cover 50, thereby enhancing the stability of the turn signal structure 100 on the cover 50 and preventing the turn signal structure 100 from easily detaching from the cover 50. Of course, in other embodiments, the number of mounting portions 13 can be set to other numbers, as long as the same effect is achieved. For example, the number of mounting portions 13 can be set to six, seven, eight, or more.

[0049] 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 invention.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
