Description

Technical Field

[0001] This utility model relates to the field of motorcycle lighting devices, and more specifically, it relates to a thick-walled turn signal light. Background Technology

[0002] As a flexible mode of transportation, the safety of motorcycles is of paramount importance. Turn signals are a key safety warning device for motorcycles, especially at the front. Their function is not only to indicate the direction of travel, but also to provide clear turning intention signals to oncoming vehicles and pedestrians during daytime driving, nighttime driving, and in adverse weather conditions, thereby effectively preventing side collisions.

[0003] Currently, common motorcycle front turn signals on the market require small size and highly adaptable shape due to the compact space and varied shapes of the front of motorcycles. However, traditional turn signals often use simple thin-walled plastic lenses or universal light distribution structures, resulting in uneven light distribution, obvious bright spots or dark areas, and insufficient visibility in strong light environments, thus weakening their warning effect. Secondly, in pursuit of aesthetic appeal, motorcycle front turn signals often employ complex irregular structures, which complicates the assembly of internal components. Traditional assembly methods are cumbersome, with inconsistent positioning benchmarks between components, leading to low assembly accuracy, poor efficiency, and difficulty in ensuring sealing performance. Rainwater and dust can easily penetrate the lamp, affecting electrical safety and accelerating lamp light decay. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a thick-walled turn signal light with uniform light effect and convenient assembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A thick-walled turn signal light includes a base shell, a lamp panel assembly, a light distribution lens, a decorative panel, and a lamp cover. The lamp panel assembly is installed inside the base shell and includes a lamp panel body and a plurality of LEDs evenly arranged along its contour edge. The light distribution lens is a thick-walled component installed at the front end of the base shell, and its inner wall is provided with a retaining ring. The light distribution lens has a polygonal ring structure adapted to the arrangement path of the LEDs. One side of the decorative panel has a flange that abuts against the retaining ring, and the other side has a connecting rod. The side wall of the base shell has a connecting protrusion with an insertion hole. A retaining plate is provided in the insertion hole, and the end of the connecting rod is connected to the retaining plate by a fastening bolt. The opening of the base shell has a stepped limiting groove, including a first limiting groove and a second limiting groove. The first limiting groove is used to install the light distribution lens, and the second limiting groove is used to install the lamp cover.

[0006] The present invention is further configured such that: the lamp panel body is provided with mounting holes, and the bottom shell is provided with lamp panel connecting posts corresponding to the mounting holes, and the lamp panel body is fixed to the inner cavity of the lamp cover by bolts.

[0007] By implementing the above technical solutions, the lamp panel assembly is securely installed, significantly improving its seismic resistance and reliability.

[0008] The present invention is further configured such that: an avoidance hole is provided on the lamp panel body for the connecting rod to pass through.

[0009] By adopting the above technical solution, interference between the connecting rod and the light panel is avoided, ensuring smooth assembly.

[0010] The present invention is further configured such that: the lens is made of PC material, has a cross-sectional width of 16mm, and has a trapezoidal ring structure.

[0011] By adopting the above technical solutions, the uniformity of light and the efficiency of light guiding are improved, thereby enhancing the visual effect.

[0012] The present invention is further configured such that the lampshade and the bottom shell are ultrasonically welded.

[0013] By adopting the above technical solutions, the sealing and connection strength are ensured, preventing water and dust from entering.

[0014] The present invention is further configured such that: a connector is provided on the back of the lamp panel body, and a wiring head is provided on one side of the bottom shell, and the connector and the wiring head are connected by a cable.

[0015] By adopting the above technical solutions, convenient and reliable electrical connections can be achieved.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. In this solution, by matching the thick-walled polygonal light distribution lens with the LED arrangement path, uniform light distribution is achieved, improving the visual indication effect. 2. In this solution, the lamp board assembly is firmly fixed to the lamp board connecting post on the bottom shell by bolts passing through the mounting holes, forming a rigid connection between the lamp board and the bottom shell, ensuring the long-term stability of the lamp bead position, and thus ensuring the accuracy and consistency of the light pattern.

[0017] 3. In this solution, the light distribution lens is a thick-walled component, which can fully disperse, guide and homogenize the light emitted by the dot-shaped LED beads, eliminate areas that are too bright or too dark, and form a continuous, full and uniform light band, which greatly improves the visibility of the motorcycle's turn indicators in complex lighting environments.

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

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] Please see Figures 1 to 4 This embodiment provides a thick-walled turn signal light for the front of a motorcycle, including a base shell 1, a lamp panel assembly 2, a lens 3, a decorative panel 4, and a lamp cover 5.

[0023] See Figure 1 and Figure 2 The lamp panel assembly 2 is installed inside the base shell 1, and includes a lamp panel body 201 and a plurality of lamp beads 202 evenly arranged along its contour edge. The base shell 1 has a plurality of lamp panel connecting posts 103, and the lamp panel body 201 has mounting holes 2011 corresponding to the lamp panel connecting posts 103. The lamp panel body 201 is fixed to the inner cavity of the lamp cover 5 by bolts. The base shell 1 is typically injection molded from PC.

[0024] During assembly, the lamp board body 201 is placed into the inner cavity of the base shell 1, and the mounting holes 2011 are fitted into the corresponding lamp board connecting posts 103. Then, bolts are screwed from the back of the lamp board into the threaded holes of the lamp board connecting posts 103, thereby fixing the lamp board assembly 2 onto the base shell 1. The lamp board body 201 is a PCB, its outline conforming to the inner cavity of the base shell 1. Multiple LED beads 202 are soldered onto the lamp board body 201, and these beads 202 are evenly arranged in single or multiple rows along the outline edge of the lamp board body 201 to form a uniform light strip. A standard waterproof connector 203 is installed on the back of the lamp board body 201. Correspondingly, a matching connector 7 is pre-installed on the side wall or rear of the base shell 1. By connecting the connector 203 and the connector 7 with a cable with mating plugs at both ends, the electrical connection between the lamp board assembly 2 and the motorcycle main cable can be quickly achieved.

[0025] See Figure 3 In this embodiment, the light distribution lens 3 is an optical component that achieves uniform light efficiency. In this embodiment, the light distribution lens 3 is a thick-walled component, made of high-transmittance and high-impact-resistant PC material through injection molding. Its cross-sectional width, i.e., the thickness of the light distribution lens 3, is preferably 16 mm. This thickness provides optimal light mixing and guiding effects for the light passing through the light distribution lens 3. The overall shape of the light distribution lens 3 is a polygonal ring structure adapted to the arrangement path of the LED beads 202. In this embodiment, a ring structure with a trapezoidal cross-section is preferred. This structure can efficiently capture the light emitted by the LED beads 202 and guide it in the desired direction.

[0026] Furthermore, a retaining ring 301 is integrally formed along the inner wall of the lens 3, and an inwardly folded flange 401 is provided on one side edge of the decorative panel 4. After assembly, the retaining ring 301 abuts against the flange 401 of the decorative panel 4, serving to limit axial movement and assist in light guiding. During assembly, this flange 401 precisely abuts against the inner side of the retaining ring 301 on the inner wall of the lens 3. At least two connecting rods 402 are fixedly provided on the other end face of the decorative panel 4. The ends of these connecting rods 402 are machined with threaded holes.

[0027] See Figure 4 and Figure 5On the inner side wall of the bottom shell 1, there are connecting protrusions 104 in number equal to the connecting rods 402. Each connecting protrusion 104 has an insertion hole 1041, and a retaining plate 1042 is provided at the bottom of the insertion hole 1041. When assembling the decorative panel 4, first align the flange 401 of the decorative panel 4 with the retaining ring 301 of the lens 3, and then insert the end of the connecting rod 402 into the insertion hole 1041 of the corresponding connecting protrusion 104 on the bottom shell 1 until the end of the connecting rod 402 abuts or approaches the retaining plate 1042. Subsequently, use a fastening bolt 6 to screw in from the outside of the connecting protrusion 104, pass through the through hole in the center of the retaining plate 1042, and finally screw it into the threaded hole at the end of the connecting rod 402 and lock it, thereby tightly connecting the decorative panel 4, the lens 3, and the bottom shell 1 into a whole, forming a stable vibration-resistant structure. To prevent the connecting rod 402 from interfering with the lamp panel assembly 2 during installation, a clearance hole 2012 is pre-drilled on the lamp panel body 201 at the position corresponding to the path of the connecting rod 402 to ensure assembly quality.

[0028] See also Figure 5 At the opening at the front end of the bottom shell 1, a stepped limiting groove is provided, including an inner first limiting groove 101 and an outer second limiting groove 102. The first limiting groove 101 is used to support and position the edge of the light distribution lens 3, ensuring that it maintains a precise relative position with the lamp beads 202 on the lamp panel assembly 2. The second limiting groove 102 is used to support and position the edge of the lamp cover 5. The lamp cover 5 is usually made of transparent PC or PMMA material and is the outermost protective cover of the lamp.

[0029] Furthermore, the fixing and sealing between the lampshade 5 and the base shell 1 employs ultrasonic welding. Energy-conducting ribs are typically provided on the mating surface of the second limiting groove 102. During welding, the edge of the lampshade 5 is placed into the second limiting groove 102, and high-frequency vibration energy is applied to the mating surface using ultrasonic welding equipment. The energy-conducting ribs melt instantly, fusing the lampshade 5 material and the base shell 1 material together under pressure. After cooling, a high-strength, highly sealing weld is formed, preventing moisture and dust from seeping into the joint and ensuring the manufacturing quality of the lamp.

[0030] Specifically, the assembly process of the turn signal light is as follows: First, the light panel assembly 2 is fixed to the base housing 1 with bolts; the connector 7 is pre-installed on the base housing 1, and the connector 203 is connected to the connector 7 with a cable. Then, the lens 3 is installed into the first limiting groove 101 of the base housing 1. Next, the flange 401 of the trim panel 4 is aligned with the retaining ring 301 of the lens 3, and the connecting rod 402 is passed through the clearance hole 2012 on the light panel and inserted into the insertion hole 1041 of the connecting protrusion 104 of the base housing 1, and locked with the fastening bolt 6. Finally, the lamp cover 5 is placed in the second limiting groove 102 and welded to the base housing 1 as a whole using ultrasonic welding equipment.

[0031] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
