[0033] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0034] This application discloses a turn signal.

[0035] A turn signal includes a housing 1, a light-emitting element 2, a light-refracting element 3, and a transparent protective housing 4. A housing cavity is formed between the housing 1 and the transparent protective housing 4, and the transparent protective housing 4 is fixed to the housing 1 by a snap-fit ​​method. The light-emitting element 2 and the light-refracting element 3 are both disposed in the housing cavity, wherein the light-emitting element 2 is fixed to the housing 1 by an adhesive method, while the light-refracting element 3 is located between the light-emitting element 2 and the transparent protective housing 4, and is pressed against the housing 1 by the transparent protective housing 4.

[0036] The housing 1 is connected to the vehicle body via the connecting part 5. During turn signal installation, the light-emitting element 2 is first placed inside the mounting slot and adhered to the inner wall of the housing 1 to improve installation convenience and stability. Next, the light-reflecting element 3 is placed on the inner wall of the housing 1 and positioned using the transparent protective shell 4. Then, the transparent protective shell 4 is threaded onto the housing 1, and the light-reflecting element 3 is pressed firmly onto the housing 1.

[0037] The inner wall of the housing 1 is provided with a plurality of positioning posts 11 circumferentially along the axis of the housing 1. The light-emitting element 2 includes a placement plate 21 and LED beads 22. The placement plate 21 is provided with a plurality of positioning holes 211 for the positioning posts 11 to be inserted. The side of the placement plate 21 contacts the inner wall of the housing 1. The LED beads 22 are mounted on the placement plate 21 and are provided circumferentially along the axis of the placement plate 21. When placing the placement plate 21, the positioning posts 11 on the housing 1 are inserted into the positioning holes 211 to position the placement plate 21, thereby improving the placement stability of the placement plate 21.

[0038] A plurality of positioning blocks 12 are circumferentially arranged on the inner wall of the housing 1 along the axial direction of the housing 1, and positioning posts 11 are placed on the positioning blocks 12. When the placement plate 21 is placed, the positioning blocks 12 and the inner wall of the housing 1 work together to position the placement plate 21. At the same time, the positioning blocks 12 create a heat dissipation space between the placement plate 21 and the inner wall of the housing 1, reducing heat accumulation on the placement plate 21. The tops of the positioning blocks 12 are flush, and the placement plate 21 contacts the positioning blocks 12. The large contact area between the placement plate 21 and the positioning blocks 12 improves the convenience and stability of the connection between the placement plate 21 and the positioning blocks 12.

[0039] A first annular placement groove 13 is formed on the inner wall of the housing 1, and the light-reflecting element 3 is arranged in an annular shape with its side positioned in the first placement groove 13. When placing the light-reflecting element 3, it is positioned by the inner wall of the first placement groove 13, thereby improving the convenience and stability of placing the light-reflecting element 3.

[0040] The inner wall of the placement shell 1 is provided with an annular second positioning groove 14. The placement shell 1 is provided with a positioning cylinder 15, and the positioning cylinder 15 is provided with an annular third positioning groove 151. The side walls of the transparent protective shell 4 are respectively placed in the second positioning groove 14 and the third positioning groove 151, and the transparent protective shell 4 presses the refracting element 3 against the placement shell 1 along the axial direction of the positioning cylinder 15. When the transparent protective shell 4 is installed on the placement shell 1, the transparent protective shell 4 is positioned by the inner walls of the second positioning groove 14 and the third positioning groove 151. At the same time, the transparent protective shell 4 presses the refracting element 3 against the inner wall of the placement shell 1, thereby improving the convenience and stability of the placement of the refracting element 3.

[0041] The outer wall of the refracting element 3 is provided with an annular pressing groove 31, and the inner wall of the transparent protective shell 4 is provided with an annular pressing block 41, which contacts the pressing groove 31. When the refracting element 3 is pressed against the pressing groove 31, the pressing block 41 on the transparent protective shell 4 presses against the pressing groove 31, thereby pressing the refracting element 3.

[0042] A connecting ring 16 is coaxially mounted on the housing 1. The outer wall of the transparent protective housing 4 and the inner wall of the connecting ring 16 are connected by threads. The relatively thick cross-section of the connecting ring 16 facilitates the setting of threads on its inner wall. A positioning ring 152 is provided on the positioning cylinder 15. The side of the transparent protective housing 4 contacts the side of the positioning ring 152 away from the positioning cylinder 15. When the transparent protective housing 4 rotates, it stops rotating after contacting the positioning ring 152, reducing the possibility of deformation of the refracting element 3 due to excessive rotation of the transparent protective housing 4.

[0043] In summary, the design of this turn signal, through its precise positioning structure and robust connection method, ensures the stability and heat dissipation performance of the light-emitting element 2 and the refractive element 3, while simplifying the installation process and improving the overall performance and service life of the turn signal.

[0044] The implementation principle of a turn signal according to an embodiment of this application is as follows: First, the light-emitting element 2 is placed and adhered to the inner wall of the placement shell 1, while the light-reflecting element 3 is located between the light-emitting element 2 and the transparent protective shell 4, and is pressed against the placement shell 1 by the transparent protective shell 4. The positioning post 11 and the positioning block 12 on the inner wall of the placement shell 1 work together to accurately position the placement plate 21 of the light-emitting element 2, while forming a heat dissipation space to reduce heat accumulation. The light-reflecting element 3 is positioned by the first placement groove 13, while the transparent protective shell 4 is positioned by the second positioning groove 14 and the third positioning groove 151, ensuring that the light-reflecting element 3 is firmly pressed against the placement shell 1. The pressing groove 31 on the outer wall of the light-reflecting element 3 interacts with the pressing block 41 on the inner wall of the transparent protective shell 4 to further press the light-reflecting element 3. Finally, the transparent protective shell 4 is connected to the connecting ring 16 on the placement shell 1 by threads, while the positioning ring 152 limits the rotation depth of the transparent protective shell 4 to prevent deformation of the light-reflecting element 3. The entire installation process aims to improve the ease of installation, stability, and heat dissipation efficiency of the turn signals, ensuring their long-term reliable operation.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
