Technical Field
[0001] This utility model relates to the technical field of high-concentration combined front and rear turn signal reflectors, and in particular to a high-concentration combined front and rear turn signal reflector with a composite curved surface reflective layer. Background Technology
[0002] Front and rear turn signal reflectors are key components of modern automotive lighting systems, and their design and performance directly affect the vehicle's lighting performance and driving safety. These reflectors typically use high-reflectivity metallic materials (such as aluminum or silver) to form a composite curved reflective layer through vacuum coating technology to achieve efficient light reflection and focusing.
[0003] The curved surface design of the reflector is usually aspherical or freeform, which can precisely control the propagation path of light and form the desired beam pattern. For example, the prior art Chinese patent announcement number "CN206920693U" provides an interleaved alignment reflector for a high-concentration compound solar module. The reflector is divided into a reflector surface A and a reflector surface B. The reflector surface A is provided with an interleaved alignment hole A, and the reflector surface B is provided with an interleaved alignment hole B. Heat sink positioning points are respectively provided on both sides of the alignment hole A and the alignment hole B. The focal point of the reflector surface A is located at the interleaved alignment hole B, and the focal point of the reflector surface B is located at the interleaved alignment hole A. This invention relates to a concentrating device for high-concentration compound solar modules. The reflector is designed with staggered alignment, which has the advantages of a small incident angle and low light efficiency loss. When applied to the primary optics of high-concentration solar modules, it can solve the problem of large incident angle and high light efficiency loss in existing high-concentration solar concentrators, and solve the problem of the inability to automatically align the primary and secondary optics in the production of high-concentration solar modules.
[0004] Currently, most front and rear lights and turn signals are integrated into one lighting area of a car. As a result, when focusing and reflecting light, it is difficult to achieve stable combined focusing of the light from the front and rear lights and turn signals if only the reflector set behind the lights is used. This greatly reduces the brightness when providing light warnings. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a high-concentration combined front and rear turn signal reflector with a composite curved surface reflective layer.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: The design includes a high-concentration combined front and rear turn signal reflector with a composite curved reflective layer, comprising a frame one, a rear reflector fixedly embedded in the inner side of the frame one, a frame two on one side of the frame one, a side center reflector fixedly embedded in the middle of the inner side of the frame two, and side auxiliary reflectors fixedly embedded at the upper and lower ends of the inner side of the frame two.

A cylinder is fixedly mounted on the surface of the connecting plate by a bracket, and a motor is fixedly mounted on the inner side of the cylinder by a bracket. The motor has a rotating shaft for driving inside, and blades are fixedly distributed on the surface of the rotating shaft.
[0007] Preferably, a plurality of mounting plates are fixedly distributed on the back of the second frame near the first frame, and the mounting plates are evenly distributed along the vertical position.
[0008] Preferably, a threaded post is welded and fixed to the surface of the mounting plate, and a collar corresponding to the position of the threaded post is fixedly installed on one side end of the first frame.

[0015] The design scheme proposed in this utility model has the following beneficial effects in application: 1. The combination of the mirror frame and the rear rearview mirror in this solution ensures the focusing performance in the front and rear directions, while the integration of the side center rearview mirror and the side auxiliary rearview mirror enhances the visibility of the lights on the side. When the turn signal is on, the combination of multiple rearview mirrors not only optimizes the side warning effect, but also maintains the clarity of observation in the front and rear through the rear rearview mirror.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Reference Figures 1-4A high-concentration combination front and rear light turn signal reflector with a composite curved reflective layer includes a frame 1. A rear reflector 11 is embedded and fixed inside the frame 1. A frame 2 12 is provided on one side of the frame 1. A side center reflector 13 is embedded and fixed in the middle of the inside of the frame 2 12. Side auxiliary reflectors 19 are embedded and fixed at the upper and lower ends of the inside of the frame 2 12. By cooperating with the rear reflector 11, the front and rear lights can have a good focusing effect in the front and rear directions when they are illuminating. The side center reflector 13 can improve the side observation effect of the front and rear lights. When the turn signal is illuminating, the side center reflector 13 and the side auxiliary reflector 19 can enhance the side warning effect of the turn signal. In addition, the rear reflector 11 can also improve the observation effect of the turn signal in both the front and rear directions. The multiple reflectors are integrated to improve the focusing warning capability of the front and rear lights and the turn signal. A heat dissipation hole 14 is provided on one side of the mirror frame 1, and a connecting plate 15 is fixedly installed on the back of the mirror frame 1 at the position of the heat dissipation hole 14. The heat dissipation hole 14 can provide auxiliary ventilation when the mirror frame 1 and the mirror frame 2 12 cover the front and rear lights and turn signals, so as to avoid the mirror frame structure blocking the heat dissipation of the lamp body. A cylinder 16 is fixedly mounted on the surface of the connecting plate 15 via a bracket. A motor 17 is fixedly mounted on the inner side of the cylinder 16 via a bracket. The motor 17 has a rotating shaft inside for driving, and blades 18 are fixedly distributed on the surface of the rotating shaft. In order to further improve the heat dissipation effect at the lamp body position, the motor 17 can be started synchronously after the lamp body starts lighting, so that the motor 17 drives the rotating shaft, and the rotating shaft can make the blades 18 rotate, which can generate airflow and improve the gas flow effect of the heat dissipation process.
[0020] Among them, several mounting plates 2 are fixedly distributed on the back of the second frame 12 near the first frame 1. The mounting plates 2 are evenly distributed along the upper and lower positions. The mounting plates 2 can ensure that the threaded post 22 has a mounting point and fits with the collar 21, ensuring the quick positioning of the first frame 1 and the second frame 12.
[0021] Among them, a threaded post 22 is welded and fixed to the surface of the mounting plate 2. A collar 21 corresponding to the position of the threaded post 22 is fixedly installed on one side end of the frame 1. The inside of the collar 21 is slidably sleeved with the surface of the threaded post 22. A nut 23 is threadedly installed on the surface of the threaded post 22. One side of the nut 23 is tightly abutted against the end face of the collar 21. When it is necessary to combine the frame 1 and the frame 22, the two frames are spliced at right angles. At this time, the threaded post 22 and the collar 21 are connected through each other. The nut 23 and the threaded post 22 are threadedly installed to each other, so that the frame 1 and the frame 22 can be stably assembled.
[0022] The frame 1 comprises, in sequence, a base layer 1101, an enhanced reflective layer 1102, an antioxidant protective layer 1103, a hard coating 1104, and a hydrophobic layer 1105. The surface of the base layer 1101 is covered with the enhanced reflective layer 1102, the surface of the enhanced reflective layer 1102 is coated with the antioxidant protective layer 1103, the surface of the antioxidant protective layer 1103 is coated with the hard coating 1104, and the surface of the hard coating 1104 is coated with the hydrophobic layer 1105.
[0023] The base layer 1101 is made of polycarbonate, a high-performance engineering plastic with excellent mechanical strength, toughness and impact resistance. It also has good transparency and heat resistance, and can maintain stable performance in high and low temperature environments. In addition, the lightweight nature of polycarbonate helps to reduce the overall weight of the reflector and improve the vehicle's fuel efficiency and performance.
[0024] Among them, the enhanced reflective layer 1102 is made of aluminum coating material. The aluminum coating has high reflectivity, which can efficiently reflect light and improve the lighting effect. The reflectivity of aluminum can reach more than 90% in the visible light range, ensuring that the reflector can provide a bright and focused beam of light. The aluminum coating has good adhesion and corrosion resistance, and can maintain stable performance under various environmental conditions.
[0025] Among them, the antioxidant protective layer 1103 is made of silicon dioxide. The silicon dioxide coating has good transparency and corrosion resistance, which can effectively protect the reflective layer from oxidation and corrosion. Silicon dioxide has high chemical stability, which can resist the erosion of various chemicals and extend the service life of the reflector. The silicon dioxide coating also has good wear resistance and scratch resistance, which can keep the surface of the reflector smooth and intact.
[0026] Among them, the hard coating 1104 is made of diamond-like carbon coating material. Diamond-like carbon coating has extremely high hardness and wear resistance, which can effectively prevent scratches and wear and extend the service life of the reflector. This coating also has good chemical stability and heat resistance, and can maintain stable performance in high temperature and corrosive environments. Diamond-like carbon coating also has a low coefficient of friction and good optical properties, which can keep the surface of the reflector smooth and transparent.
[0027] The hydrophobic layer 1105 is made of fluorinated silicon coating material. The fluorinated silicon coating has extremely low surface energy, which can form a highly hydrophobic surface, effectively preventing water droplets and dirt from adhering to the surface of the reflector. This coating also has good chemical resistance and weather resistance, and can resist the erosion of various chemicals and ultraviolet rays, extending the service life of the reflector. The fluorinated silicon coating also has good transparency and optical properties, which can maintain the clarity and reflection effect of the reflector.
[0028] Operating principle: The rear reflector 11 embedded inside the first mirror frame 1 of this solution, through its composite curved surface structure including an aluminum coating of enhanced reflective layer 1102, efficiently focuses the light emitted by the front and rear lights to form a high-intensity directional beam, ensuring illumination and warning effects in both directions. Simultaneously, the side center reflector 13 and side auxiliary reflector 19 inside the second mirror frame 12 adopt an asymmetrical curved surface design, diffusing the turn signal light to the sides and enhancing reflectivity, significantly improving visibility from the side. When the turn signal is activated, the side center reflector 13 preferentially reflects horizontal light, while the side auxiliary reflector 19 supplements the light at the vertical angle, forming multi-angle coverage. The rear reflector 11 synchronously reflects the turn signal to the front and rear, achieving 360° warning without blind spots. The synergistic effect of each reflector depends on the right-angle splicing structure of the first frame 1 and the second frame 12. Through the sliding sleeve of the collar 21 and the threaded post 22 and the fastening of the nut 23, the precise alignment of the optical components is ensured, and the light path is avoided. The heat dissipation hole 14 of the mirror frame 1 runs through its back, allowing the heat generated when the lamp is working to be discharged through natural convection. To further enhance heat dissipation, the cylinder 16 fixed on the connecting plate 15 has a built-in motor 17. The blades 18 driven by its shaft generate forced airflow during operation, accelerating the air exchange inside and outside the heat dissipation hole 14. The motor 17 starts synchronously with the lamp illumination. Through the directional flow of air, it is discharged from the inside of the mirror frame 1 through the heat dissipation hole 14 to the outside, reducing the internal temperature of the mirror frame. The multi-layer structure design of the mirror frame 1, such as the heat resistance of the polycarbonate base layer 1101 and the thermal stability of the hard coating 1104, ensures that the mechanical strength does not deform under high temperature conditions. The silica material of the anti-oxidation protective layer 1103 further prevents thermal oxidation from damaging the reflective layer 1102. The heat dissipation system is isolated from the mounting plate 2 area of the mirror frame 2 12 to prevent heat from being conducted to the turn signal reflector assembly, ensuring the optical performance stability of the side center reflector 13 and the side auxiliary reflector 19.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
