Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to a sealing flexible connection structure for automotive lighting and an automotive lighting system equipped with the aforementioned structure. Background Technology

[0002] Digital projection headlights (DLP), as a novel automotive lighting technology, offer excellent interactive capabilities in various scenarios. For example, while the vehicle is in motion, DLP headlights can assist with high and low beam functions to enhance illumination, and can also project different signal markings onto the ground, allowing other drivers and pedestrians to recognize the signals in advance and increasing safety when passing other vehicles. Furthermore, when the vehicle is stationary, DLP headlights can project images onto a wall, providing a good entertainment function. In conclusion, the application of digital projection headlights in automotive headlights is becoming increasingly widespread.

[0003] The investigation revealed that most DLP lamps currently on the market are installed inside the lamp body using rigid connections such as clips and screws. While this achieves some dimming functionality, it is not suitable for large-angle or wide-range adjustments. Furthermore, existing DLP lamps are usually completely enclosed within the lamp, which is very detrimental to heat dissipation, causing excessively high internal temperatures and affecting the normal operation of the DLP function. To improve heat dissipation, the DLP's heat dissipation structure needs to be located on the outside of the lamp body, typically using a sealing ring structure at the opening of the lamp housing. However, conventional sealing ring structures have limited deformation capacity, leading to sealing failures during dimming.

[0004] To address the aforementioned issues, we developed a flexible sealing connection structure for automotive lights. This structure connects the DLP (Digital Light Port) to the lamp housing, ensuring a tight seal while enabling wide-angle dimming of the DLP. Utility Model Content

[0005] This utility model provides a sealed flexible connection structure for a vehicle lamp. The structure mainly includes an outer lens, a light source assembly, a lamp housing, and a flexible connection assembly. The light source assembly is fixedly connected to the lamp housing via the flexible connection assembly and can be adjusted for dimming. The lamp housing is sealed to the outer lens, thereby forming a complete vehicle lamp.

[0006] In the above solution, the light source assembly includes a light source module, a horizontal adjustment system, and a vertical adjustment system. One end of each of the horizontal and vertical adjustment systems is fixed to the lamp housing, and the other end is fixedly connected to the light source module. Each system can move the light source module horizontally and vertically, respectively, thereby achieving light adjustment in the left-right horizontal direction and the up-down vertical direction.

[0007] In the above scheme, the light source module is specifically a digital projection headlight (DLP).

[0008] In the above solution, the vehicle headlight's sealed flexible connection structure also includes a cooling fan. The cooling fan is fixedly connected to the back of the light source module with screws and is located outside the headlight body. The cooling fan can quickly dissipate the heat generated by the light source module during operation into the headlight, thereby improving the headlight's reliability and lifespan.

[0009] In the above solution, the flexible connection assembly includes a sealed flexible connector, bracket A, and bracket B. Both ends of the sealed flexible connector are fixedly connected to bracket A and bracket B, respectively. Bracket A and bracket B are fixedly connected to the lamp housing and the light source assembly, respectively, thereby achieving a flexible connection between the light source assembly and the lamp housing. This provides both sealing and waterproofing while also enabling a wider range of dimming.

[0010] In the above scheme, the sealing flexible connector is specifically a hose or corrugated pipe made of materials such as rubber or plastic (e.g., plastic composite materials).

[0011] In the above solution, sealing grooves are provided on both the light source assembly and the lamp housing, and matching bosses are provided on both ends of the sealing flexible connector. The bosses on the sealing flexible connector are respectively inserted into the sealing grooves on the light source assembly and the lamp housing and pressed by bracket A and bracket B, thereby realizing the flexible connection and sealing between the light source assembly and the lamp housing.

[0012] In the above scheme, stent A and stent B can be integrally molded (i.e. integrated on one stent) or separately injection molded (i.e. divided into two different stents).

[0013] The second objective of this utility model is to provide a vehicle lamp equipped with the aforementioned vehicle lamp sealing flexible connection structure.

[0014] Compared with existing automotive projection headlights and their internal sealing rings, the automotive headlight sealing soft connection structure of this utility model has advantages such as good sealing performance, compact structure, high space utilization, excellent heat dissipation performance, low cost, and comprehensive functions. More importantly, it can adapt to the large adjustment range of DLP in different directions. By appropriately deforming the sealing soft connection, it adapts to the position and angle changes of the DLP module during the dimming process, ensuring a better automotive headlight sealing effect.

[0020] To enable those skilled in the art to fully understand the technical solution and beneficial effects of this utility model, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be emphasized that these embodiments and drawings are merely some implementations of this utility model; many other implementations are also possible. Any simple improvements or substitutions made based on these embodiments will fall within the protection scope of this utility model.

[0021] like Figure 1-4 The digital projection headlight shown can be designed as a standalone lamp body or integrated with other vehicle lights such as high and low beam headlights into the same lamp body. This means that the sealing connection structure for vehicle lights provided by this invention can be applied to other types of combined vehicle lights.

[0022] like Figure 1-4 As shown, this digital projection headlight mainly includes a DLP headlight 1, a cooling fan 2, an outer lens 3, a lamp housing 4, a sealed flexible connector 5, bracket A 6, and bracket B 7. The lamp housing 4 is the main assembly component, and the other parts are directly or indirectly fixed to it. The specific structure and interconnections of each component will be described in detail below.

[0023] The DLP headlight 1 uses multiple LEDs as its light source. These LEDs are controlled to illuminate and project light outwards, achieving the DLP function. To achieve better lighting performance, the DLP headlight is also equipped with corresponding dimming structures, such as a vertical adjustment system and a horizontal adjustment system, to adjust the direction and angle of the light source. The horizontal and vertical adjustment systems and their associated fixing structures can be found in the inventor's previously published patent CN223294673U. Of course, other dimming structures can also be applied to the DLP headlight described in this application.

[0024] The cooling fan 2 is fixed to the back of the DLP headlight 1 with multiple screws. When the cooling fan 2 is powered on, it uses airflow to carry away the heat generated by the DLP headlight after it is turned on, preventing it from overheating and being damaged.

[0025] The outer lens 3 is injection molded from transparent plastic (such as PC, PMMA, etc.), and is sealed to the lamp housing 4 with glue, thereby encapsulating the DLP headlight 1 inside the vehicle light.

[0026] The lamp housing 4 is injection molded from opaque engineering plastic (such as ABS, PC, etc.). A rectangular groove is provided on its back, in which the cooling fan 2, sealing flexible connector 5, bracket A 6, bracket B 7, etc. are installed.

[0027] The sealing flexible connector 5 is a hose or corrugated pipe made of composite materials (such as rubber or plastic), with protrusions or bosses at both ends. Although the sealing flexible connector 5 will deform under stress, it can still maintain a good sealing effect.

[0028] Both brackets A6 and B7 are injection molded from opaque plastic. They can be made into two brackets of different sizes separately, or integrated into the same bracket. The shape of these two brackets is similar to the rectangular groove on the back of the lamp housing 4, making it easy to install in that position.

[0029] The assembly method of this digital projection headlight is as follows: First, use screws, clips, and other connectors to fix the DLP headlight 1 to the lamp housing 4, ensuring that it can move within a certain range for dimming. Next, attach the front end of the sealing flexible connector 5 ( Figure 3-4 The protrusion at the right end of the headlight 1 is pressed into the groove on the back of the DLP headlight 1. After the protrusion is pressed down by bracket A6, bracket A6 is fixed to the DLP headlight 1 by screws or clips. The rear end of the sealing flexible connector 5 ( Figure 3-4 The left end of the lamp housing (often referred to as the lamp housing 4) is fixed to the lamp housing in a similar manner, as follows: The boss at the rear end of the sealing flexible connector 5 is pressed into the groove of the lamp housing 4. After the boss is pressed down with bracket B 7, bracket B 7 is fixed to the lamp housing 4 using screws or clips. Next, the cooling fan 2 is fixed to the back of the DLP headlight 1, ensuring it faces the heat sink of the DLP headlight 1 for efficient heat dissipation. Finally, the lamp housing 4 and the outer lens 3 are bonded together using sealant, thus completing the encapsulation of the vehicle light.

[0030] The above-mentioned vehicle light sealing soft connection structure provided by this utility model has a good sealing effect and is not affected by horizontal or vertical dimming. It has many advantages such as low cost, compact structure, high space utilization and comprehensive functions.
