Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a decorative frame for a headlight and a headlight assembly. Background Art

[0002] Car lights are not only a vital component of ensuring driving safety but also a key element in enhancing the vehicle's overall aesthetics. To enhance the visual appeal of car lights, decorative frames are often placed around them. These frames not only enhance the vehicle's appearance but also secure and protect the lights. Currently, decorative frames are primarily manufactured through injection molding, with light-transmitting areas defined in specific locations to allow light to emanate from these designated areas, meeting the lighting requirements of the various functions of the headlights. However, as consumers' expectations for vehicle exterior design continue to rise, traditional decorative frame designs are no longer able to meet market demands.

[0003] Existing decorative frame designs have several limitations. For one thing, existing decorative frames are mostly split, meaning the translucent and opaque portions of the decorative frame need to be injection-molded separately and then connected via screws. This inevitably creates a gap at the joint between the translucent and opaque portions. During vehicle operation, this gap can cause the decorative frame to experience greater stress due to vibration, increasing the risk of breakage and thus shortening its service life. On the other hand, traditional decorative frame designs are often relatively simple and lack a sense of hierarchy, making it difficult to meet the demands of today's consumers for a more diverse and personalized automotive exterior design. With the development of society, people's aesthetic standards for automotive appearance are constantly improving, placing higher demands on the design of decorative frames. Utility Model Content

[0025] The present invention will be further described in detail below with reference to the specific embodiments of the drawings, but the protection scope of the present invention is not limited thereto.

[0026] Figure 1-Figure 2This is a specific embodiment of the decorative frame for a headlight of the utility model. The decorative frame body 1 is an integral injection-molded structure having a hollow area 2, a driving direction indication area (3, 4), a personalized area 5, and a non-light-transmitting area. Thus, the non-light-transmitting area, the driving direction indication area (3, 4), and the personalized area 5 no longer need to be connected by connectors such as screws, thereby eliminating the assembly process between the non-light-transmitting area, the driving direction indication area (3, 4), and the personalized area 5. Naturally, when considering the overall weight of the decorative frame, the weight of connectors such as screws is also unnecessary. Furthermore, the gap that inevitably exists between the non-light-transmitting area, the driving direction indication area (3, 4), and the personalized area 5 when connected by connectors is avoided, thereby avoiding the decorative frame from generating greater stress due to vibrations during driving caused by the gap. Furthermore, during the production process, only the mold for the decorative frame as a whole needs to be designed, rather than the molds for multiple components, thereby reducing the number of mold openings and reducing costs. In other words, the setting of the integral injection molding structure can not only reduce the use of screws and reduce the overall weight of the decorative frame, but also reduce the assembly process between the various parts, improve the vibration resistance, and reduce the number of mold openings. The back of the non-transparent area is coated with a black coating, and the black coating is removed by laser engraving at the corresponding positions on the back of the body 1 to form the driving direction indication area (3, 4) and the personalized area 5 respectively. Specifically, the body 1 can be firstly formed by integral injection molding using a translucent material, and then the black coating is sprayed on the back of the body to form an opaque layer covering the back of the translucent material. The black coating is then removed by laser engraving at the corresponding positions on the back of the translucent material to expose the translucent material, which serves as the driving direction indication area (3, 4) and the personalized area 5 respectively, thus obtaining the decorative frame. Alternatively, when applying the black coating, a mask is attached to the corresponding position on the back of the body 1. The mask can prevent the black coating from being applied to the body to which the mask is attached. After the mask is removed, the area is free of the black coating, thus forming the driving direction indication area (3, 4) and the personalized area 5 respectively, thus obtaining the decorative frame described in the utility model. Compared to decorative frames produced using two-shot injection molding, the resulting decorative frame does not require expensive two-shot injection molding machines, thus reducing costs. Compared to secondary injection molding, the decorative frame does not require removing the primary molded product and placing it back on another injection molding machine for remolding, as is the case with secondary injection molding. This reduces the number of injections, the number of mold openings, and the production process compared to secondary injection molding. The main body 1 is made of PP or PC, which is lighter than glass or metal, reducing the overall weight of the headlight and lowering its cost. Several clips 6 are provided around the main body 1, which allow the decorative frame to be attached to the lamp housing, making it easier to assemble and disassemble the decorative frame.

[0027] The hollowed-out area 2 is located in the middle of the main body 1 and extends through it from front to back, accommodating the headlight light source and lens assembly. There are two hollowed-out areas 2, one for the high beam and one for the low beam. Because both high and low beams first reflect light from the light source through a reflector bowl onto the lens, where it then forms a parallel beam for emission, enhancing the overall lighting effect, the high and low beams are both relatively long and hollowed out. This allows portions of the high and low beams to extend through the hollowed-out areas 2 and out of the decorative frame.

[0028] The driving direction indicator areas (3, 4) are located on the front of the main body 1 and are used to transmit indicator lights. Subject to compliance with regulations, the driving direction indicator areas (3, 4) can transmit specific light as needed to provide guidance to other vehicles and pedestrians, such as turn signals and position lights. The driving direction indicator area 3 is located below the front of the hollow area 2 and extends horizontally from the left side of the main body 1 to the right side of the main body 1. This provides a certain length of driving direction indicator area 3, making the light passing through the driving direction indicator area 3 more eye-catching. The driving direction indicator area 4 is located on one side of the hollow area 2 and can be located on a side away from the left-right centerline of the vehicle. The personalized area 5 is located in the empty area of the decorative frame and is composed of multiple light-transmitting portions, with an LED lamp bead corresponding to the rear side of each light-transmitting portion. The shape of the light-transmitting portion is one or more combinations of rectangles, triangles, circles, ellipses, hearts, five-pointed stars, and regular polygons. The light-transmitting portions can be arranged in a variety of shapes as needed. These could include multiple rows and columns of equally spaced light-transmitting portions, multiple rows of light-transmitting portions with each row forming a wave pattern, or triangles, circles, ovals, hearts, five-pointed stars, or regular polygons. This allows for personalized design and enhanced aesthetics. When specific locations and numbers of LEDs are activated, light passing through the corresponding light-transmitting portions creates unique shapes, enhancing the overall aesthetic and meeting today's consumer demand for diverse and personalized automotive exterior designs.

[0029] A vehicle lamp assembly includes a light source, a decorative frame, a lamp housing, and a lampshade. The lampshade is detachably connected to the lamp housing. The light source and decorative frame are located between the lamp housing and the lampshade. Thus, the light source and decorative frame are accommodated in the space between the lamp housing and the lampshade. The lamp housing and the lampshade protect the internal components. A body 1 is provided with a plurality of clips 6 around the periphery, which can be used to clip the decorative frame to the lamp housing. The lamp housing is used to connect to the vehicle body, and the lampshade is made of a translucent material to transmit light while protecting other internal components. The light source is located at the rear side of the decorative frame, and a group of light sources are arranged at the rear sides of the hollow area 2, the driving direction indication area (3, 4), and the personalized area 5. The light source at the rear side of the personalized area 5 is composed of a plurality of LED lamp beads with the same number and corresponding positions as the light-transmitting parts. The plurality of LED lamp beads are divided into a plurality of groups of LED lamp beads, each group of LED lamp beads includes at least one LED lamp bead, and different groups of LED lamp beads are connected in parallel. A group of LED lamp beads is turned on and off by a switch, so that a group of LED lamp beads can be controlled separately. When the LED lamp beads at a specific position and number are controlled to light up, the light can form a characteristic shape when passing through the corresponding light-transmitting part, thereby improving the overall aesthetic feeling and meeting the current consumer demand for diversified and personalized automobile exterior design. Moreover, each group of LED lamp beads includes at least one LED lamp bead, so that a switch controls a group of LED lamp beads to light up, thereby reducing the number of switches, simplifying control, and reducing costs.
