Description

Technical Field

[0001] This utility model relates to the field of vehicle component technology, and in particular to a vehicle die-cast backlight component with built-in reflective function. Background Technology

[0002] With the popularization of new energy vehicles, the requirements for high brightness and shock resistance of automotive screen die-cast backlight modules have increased. The design requirements for automotive backlight modules are to keep the structure simple, the function unchanged, the appearance beautiful, and the components simplified. On the contrary, end customers are gradually increasing their quality requirements, which prompts designers to propose innovative integration and quality improvement and efficiency enhancement based on existing component materials.

[0003] Traditional die-cast backlight module designs consist of a die-cast part, a reflective film, a light guide plate, a diffuser film, a lower light enhancement film, an upper light enhancement film, a middle sheet metal panel, and foam adhesive in sequence. This traditional die-cast backlight module design involves adding an extra reflective film during assembly, which hinders yield and production efficiency. Furthermore, the reflective film is assembled within the die-cast structural components, which carries the risk of white spots due to friction and extrusion, as well as the risk of film arching and wrinkling under harsh conditions such as ultra-high temperatures. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a vehicle-mounted die-cast backlight assembly with built-in reflective function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle-mounted die-cast backlight assembly with built-in reflective function, including a base plate, a skirt installed along one edge of the base plate, the skirt being a support plate perpendicular to the base plate, a painted surface provided on the side of the base plate near the skirt, and a backlight module provided inside the skirt.

[0006] The painted surface is a film covering the base plate, and white ink is sprayed on the film, while the backlight module is covered on the painted surface.

[0007] Preferably, the white ink is a high diffuse reflectance white ink for photovoltaic glass, a white near-infrared high reflectance pigment, or a white reflective ink.

[0008] Preferably, the backlight module includes a light guide plate, a diffusion film, a lower brightness enhancement plate, and an upper brightness enhancement plate, which are arranged adjacent to each other in sequence, with the light guide plate positioned close to the painted surface.

[0009] Preferably, a frame is provided on the side of the backlight module away from the base plate, and a connecting plate is installed along the edge of the frame away from the base plate. Several spaced limiting plates are installed on the outer wall of the connecting plate, and a limiting groove is opened on the skirt edge, with the limiting groove and the limiting plate corresponding to each other.

[0010] Preferably, the frame is secured to the skirt edge by a buckle on one side.

[0011] Preferably, foam adhesive is installed on the side of the connecting plate away from the frame.

[0012] Preferably, at least one mounting base is installed on the side of the base plate away from the skirt, and the mounting base is provided with screw holes.

[0013] The design scheme proposed in this utility model has the following beneficial effects in application:

[0014] 1. This utility model integrates the die-cast parts into a single component by applying a film and spraying white ink after the die-cast parts are formed. While achieving the same optical brightness, it also eliminates the need for post-assembly of the reflective film, saving costs. Furthermore, the absence of a film inside the backlight module avoids friction and wrinkles, improving precision and stability.

[0015] 2. This utility model has excellent high temperature resistance and weather resistance through the high reflectivity coating (such as white ink for photovoltaic glass or near-infrared high reflectivity pigment) on the painted surface, which is suitable for harsh vehicle environments and is not prone to aging or failure after long-term use.

[0021] 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.

[0022] Reference 1- Figure 4A vehicle-mounted die-cast backlight assembly with built-in reflective function includes a base plate 1, a skirt 2 installed along one edge of the base plate 1, the skirt 2 being a support plate perpendicular to the base plate 1, and at least one mounting seat 13 installed on the side of the base plate 1 away from the skirt 2. The mounting seat 13 is provided with screw holes. In actual use, bolts or screws can be taken out, passed through the mounting surface, and rotated into the screw holes of the mounting seat 13, thereby fixing the base plate 1 to the vehicle frame.

[0023] It should be noted that traditional backlight components are composed of die-cast parts, reflective film, light guide plate, diffuser film, lower light enhancement, upper light enhancement, middle sheet metal, and foam adhesive in sequence. The backlight component is processed through a series of operations such as die casting, desprue, deburring, grinding, CNC machining, shaping, magnetic grinding, cleaning, inspection and packaging.

[0024] A painted surface 11 is provided on the side of the base plate 1 near the skirt 2, and a backlight module is also provided inside the skirt 2. The painted surface 11 is a film covering the base plate 1, and white ink is sprayed on the film. The backlight module is covered on the painted surface 11. The white ink is high diffuse reflection white ink for photovoltaic glass, white near-infrared high reflective pigment, and white reflective ink.

[0025] Specifically, in use, the backlight component uses a painted surface 11 instead of the reflective film in the original process. The painted surface 11 with its own reflective function eliminates the step of separately attaching the reflective film in the traditional design, reduces assembly steps, improves production yield and efficiency, and avoids the risk of white spots caused by friction and extrusion during the assembly process of traditional reflective films, as well as the problem of film wrinkles under high temperature environments.

[0026] It should be noted that the backlight module includes a light guide plate 3, a diffuser film 4, a lower light enhancement plate 5, and an upper light enhancement plate 6. The light guide plate 3, diffuser film 4, lower light enhancement plate 5, and upper light enhancement plate 6 are arranged adjacent to each other in sequence, and the light guide plate 3 is positioned close to the painted surface 11. In actual use, the backlight assembly is processed through a series of operations such as die casting, descaling, deburring, polishing, CNC machining, shaping, magnetic grinding, cleaning, painting, inspection, and packaging. The installation of the reflective film is omitted, saving assembly steps.

[0027] Furthermore, a frame 7 is provided on the side of the backlight module away from the base plate 1, and a connecting plate 8 is installed along the edge of the frame 7 away from the base plate 1. Several spaced limiting plates 9 are installed on the outer wall of the connecting plate 8, and a limiting groove 10 is opened on the skirt 2. The limiting groove 10 corresponds to the limiting plate 9, pressing the backlight module in the skirt 2 to improve the stability of the backlight module in the skirt 2. Furthermore, the frame 7 is fixed to the skirt 2 by a buckle 14 on one side, connecting and fixing the frame 7 and the skirt 2, thereby improving the fixing stability of the frame 7 in the skirt 2 and further improving the fixing effect of the frame 7 on the backlight module.

[0028] It should be further noted that foam adhesive 12 is installed on the side of the connecting plate 8 away from the frame 7 to improve the cushioning, sealing, filling properties and the fixing function of the adhesive.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
