Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle lighting technology, specifically, it relates to a turn signal assembly with uniform brightness and a high safety factor. Background Technology
[0002] With rising living standards and an increasingly fast pace of life, automobiles have become an indispensable means of transportation, and automotive lighting is a crucial component. Vehicle manufacturers, component suppliers, and users are no longer solely focused on vehicle performance, safety, and fuel efficiency; they are increasingly demanding multifunctional automotive parts. For example, front combination headlights incorporate multiple functions, such as daytime running lights, turn signals, high beams, and low beams.
[0003] One of the key factors contributing to traffic accidents during turns is the increased blind spots, narrowed field of vision, or understeer. To prevent such accidents, a crucial measure is to always use turn signals in advance. This allows following vehicles to understand the turning pattern and make informed decisions, increasing the driver's safety. Current turn signals use a single bulb with a small light source. Some may have a flat light guide plate, but this is still insufficiently noticeable and results in uneven brightness. Especially when pedestrians or electric vehicle riders are far away, they may not be able to quickly perceive the turn signal and make appropriate judgments, increasing the risk of accidents. Therefore, improvements to existing turn signals are urgently needed. Utility Model Content
[0004] In view of this, the technical problem to be solved by this utility model is to provide a turn signal assembly with uniform brightness and high safety factor, avoiding the troubles of previous turn signal structures being simple, light sources being small and not uniform enough, and warning effects being weak.
[0005] To solve the above-mentioned technical problems, this utility model discloses a turn signal assembly with uniform brightness and a high safety factor, comprising:
[0006] The turn signal cup and the front turn signal guide plate are provided. The turn signal cup has a turn signal hole for mounting the turn signal. The turn signal guide plate has a main light guide plate facing the turn signal hole, an inner light guide plate and an outer light guide plate, which are located on the left and right sides of the main light guide plate and bend inward. The angle between the inner light guide plate and the main light guide plate is an acute angle, and the angle between the outer light guide plate and the main light guide plate is an obtuse angle. A light guide ridge is provided on the inner side of the turn signal guide plate, and an inwardly recessed step is provided on the bottom of the outer side.
[0007] According to one embodiment of the present invention, the light guide ribs of the main light plate are arranged horizontally, and a rectangular portion is provided in the center; the width of the light guide ribs of the inner light guide plate and the outer light guide plate gradually increases from back to front, and they are connected to the light guide ribs of the main light plate with equal diameter.
[0008] According to one embodiment of the present invention, the turn signal cup has forward-facing flat plates extending from its upper and lower sides.
[0009] According to one embodiment of the present invention, the upper front end of the turn signal cup is provided with two positioning buckles, and the positioning buckles are not parallel.
[0010] According to one embodiment of the present invention, both the turn signal cup and the turn signal guide plate are provided with multiple mounting brackets.
[0011] Compared with the prior art, the present invention can achieve the following technical effects:
[0012] The main light-guiding plate, in conjunction with the inner acute-angled and outer obtuse-angled light guide plates, expands the light diffusion range through refraction at different angles, avoiding the central bright spot or edge dark area of traditional turn signals. The horizontal ridges of the main light-guiding plate work in conjunction with the gradually widening ridges of the inner / outer light guide plates to ensure that the light is emitted evenly after multiple refractions, resulting in a more balanced brightness distribution and improved signal recognition.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. Attached Figure Description

Detailed Implementation
[0020] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.
[0021] Please refer to Figures 1 to 3 , Figure 1 This is a front view of a turn signal assembly with uniform brightness and a high safety factor according to an embodiment of the present invention; Figure 2 This is an exploded view of a turn signal assembly with uniform brightness and a high safety factor according to an embodiment of this utility model; Figure 3 This is a schematic diagram of the turn signal light guide plate according to an embodiment of the present utility model.
[0022] As shown in the figure, a turn signal assembly with uniform brightness and high safety factor includes: a turn signal cup 10 and a turn signal light guide plate 20 on the front side. The turn signal cup 10 has a turn signal hole 30 for mounting the turn signal. The turn signal light guide plate 20 has a main light guide plate portion 41 facing the turn signal hole 30, an inner light guide plate portion 42 and an outer light guide plate portion 43 located on the left and right sides of the main light guide plate portion 41 and bent inward. The inner light guide plate portion 42 and the main light guide plate portion 41 form an acute angle, and the outer light guide plate portion 43 and the main light guide plate portion 41 form an obtuse angle. A light guide rib 50 is provided on the inner side of the turn signal light guide plate 20, and an inner recessed stepped portion 60 is provided on the bottom of the outer side.
[0023] In one embodiment of this utility model, the turn signal cup 10 and the turn signal light guide plate 20 constitute a turn signal assembly. Turn signal bulbs are installed through the turn signal hole 30 and integrated into the vehicle body. The turn signal light guide plate 20 includes a main light guide plate 41, an inner light guide plate 42, and an outer light guide plate 43, forming a U-shaped fold. The inner light guide plate 42 has an acute angle, and the outer light guide plate 43 has an obtuse angle. By refracting light at different angles, the light diffusion range is expanded, avoiding the central bright spot or edge dark area of traditional turn signals. Furthermore, the point light source of the turn signal is transformed into a surface light source, increasing the illumination range and enhancing warning effectiveness. In addition, the three-sided emission results in more uniform light brightness.
[0024] The turn signal light guide plate 20 has a light guide ridge 50 on its inner side, which can further refract the light multiple times and emit it evenly, resulting in a more balanced brightness distribution and improved signal recognition. The outer bottom has an inwardly recessed stepped section 60, which creates a sense of layering and makes the turn signal indication more intuitive.
[0025] The light guide ribs 50 of the main light plate part 41 of this utility model are arranged horizontally to emit light evenly, and a rectangular part 51 is provided in the center to improve the central warning effect; the width of the light guide ribs 50 of the inner light guide plate 42 and the outer light guide plate part 43 gradually increases from back to front, and they are connected to the light guide ribs 50 of the main light plate 41 with equal diameter, so as to play a synergistic role and continuously converge and turn the light to the front.
[0026] The turn signal cup 10 has forward-facing flat plates extending from the upper and lower sides, which increases the installation contact area and prevents light from scattering. Combined with the "wedge-tightening" effect of the upper non-parallel positioning buckle 70, it prevents the component from vibrating and loosening.
[0027] In addition, both the turn signal cup 10 and the turn signal light guide plate 20 are equipped with multiple mounting brackets 80, which support quick and accurate assembly and reduce production and debugging costs.
[0028] In summary, this utility model utilizes a main light guide plate with inner acute and outer obtuse angle light guide plates to expand the light diffusion range through refraction at different angles, avoiding the central bright spot or edge dark area of traditional turn signals. The horizontal ridges of the main light guide plate work in conjunction with the gradually widening ridges of the inner / outer light guide plates to ensure that the light is emitted evenly after multiple refractions, resulting in a more balanced brightness distribution and improved signal recognition.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
