Description

Technical Field

[0001] This utility model relates to the technical field of dual-beam lens modules, specifically a dual-beam lens module for automotive high and low beams that is easy to assemble. Background Technology

[0002] The bi-xenon projector module is a core technology in modern automotive lighting systems. It integrates the functions of high beam and low beam into a compact module, achieving switching between the two lighting modes through innovative optical design and electronic control. Compared to traditional split headlights, this module has advantages such as smaller size, lighter weight, lower energy consumption, and higher luminous efficiency. It has become the mainstream configuration in current mid-to-high-end models and is gradually becoming more common in entry-level models.

[0003] The authorized publication number is CN218494876U, titled "A Car Light Module for Easy Quick Lens Installation and Replacement." It states that "by pushing the two push plates 13 on both sides to move the two pins 14 away from each other, then inserting the lens 3 into the circular slot 4 and releasing the two push plates 13, the two pins 14 will spring into the two slots 5 under the elastic force of the two springs 12 for locking and fixing, achieving a quick installation effect." However, when installing the lens 3, the position of the lens 3 needs to be adjusted multiple times to align the pins 14 with the slots 5 to achieve fixation, which is time-consuming and results in low assembly efficiency. Furthermore, after prolonged use, the springs 12 are prone to expansion and contraction under dynamic loads, causing the pins 14 to shift, leading to insufficient locking force and affecting the stability of the lens 3.

It can lock and fix the lens, improve the sealing and stability of the connection between the lens and the lens bracket, and has the advantages of simple and convenient operation and high assembly efficiency, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bi-xenon lens module for automobiles that is easy to assemble, comprising a mold housing body and a lens bracket connected to the end of the mold housing body. The lens bracket is provided with a lens, and the lens bracket is connected to a positioning mechanism for positioning the lens. The positioning mechanism includes multiple positioning posts and multiple wedges. The wedges are connected to the top of the positioning posts, and the wedges are connected to a drive mechanism for driving the multiple positioning posts to rise and fall synchronously. The outer side of the lens is provided with a positioning groove that matches the positioning posts.

[0006] Preferably, the positioning mechanism further includes multiple guide holes and multiple sliding grooves. The guide holes are disposed on the lens bracket and are used to guide the positioning post. The sliding grooves are disposed on the wedge block, and the driving mechanism is connected to the sliding grooves.

[0007] Preferably, the positioning post is slidably connected to the guide hole, and the bottom of the positioning post has a frustum-shaped structure.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 This utility model provides an easy-to-assemble automotive high and low beam dual-beam lens module, including a mold housing body 1 and a lens bracket 2 connected to the end of the mold housing body 1. The lens bracket 2 is provided with a lens 7, and the lens bracket 2 is connected to a positioning mechanism for positioning the lens 7. The positioning mechanism includes multiple positioning posts 16 and multiple wedges 11. The wedges 11 are connected to the top of the positioning posts 16, and the wedges 11 are connected to a drive mechanism for driving the multiple positioning posts 16 to rise and fall synchronously. The outer side of the lens 7 is provided with a positioning groove 8 that matches the positioning posts 16.

[0019] There are typically three positioning posts 16, with an included angle of 120° between adjacent posts. Correspondingly, there are also three positioning slots 8 and three limiting blocks 6. During assembly, the lens 7 is inserted into the lens holder 2, and then the drive mechanism drives the wedge block 11 and the positioning posts 16 to move synchronously towards the centerline of the lens holder 2. The centerline is... Figure 2 In step A, the positioning pin 16 is pressed against the positioning groove 8 to lock and fix the lens 7, thereby improving the stability of the lens 7 installation. The operation is simple and convenient, and the assembly efficiency is high. Finally, the positioning bolt 4 is used to lock the moving sleeve 3 to prevent the positioning pin 16 from loosening.

[0020] The positioning mechanism also includes multiple guide holes and multiple slides 13. The guide holes are set on the lens bracket 2 and are used to guide the positioning post 16. The slides 13 are set on the wedge block 11 and the drive mechanism is connected to the slides 13.

[0021] The positioning post 16 is slidably connected to the guide hole, improving the stability of its lifting and lowering. The bottom of the positioning post 16 is a frustum-shaped structure, as is the positioning groove 8. As the positioning post 16 gradually moves, it applies a pushing force to the lens 7 towards the retaining ring 9 until the positioning post 16 is fully connected to the positioning groove 8. At this point, the lens 7 is pressed against the rubber pad 10, which improves the stability of the lens 7 installation and also ensures the seal between the lens 7 and the lens bracket 2.

[0022] The driving mechanism includes a movable sleeve 3, multiple sliding blocks 14, multiple pushing blocks 15, and a positioning bolt 4. The movable sleeve 3 is slidably connected to the lens bracket 2. The pushing blocks 15 are connected inside the movable sleeve 3. The sliding blocks 14 are fixed to the pushing blocks 15 and are slidably connected to the slide groove 13. The positioning bolt 4 is used to position the movable sleeve 3. The sliding blocks 14 cannot be disengaged from the slide groove 13. During the forward movement of the movable sleeve 3, the three pushing blocks 15 are moved forward simultaneously, causing the sliding blocks 14 to slide relative to the slide groove 13. This allows the three wedges 11 and the three positioning posts 16 to move synchronously towards direction A, facilitating the limiting and fixing of the lens 7. When the lens 7 needs to be disassembled, the movable sleeve 3 is pulled backward, simultaneously causing the three pushing blocks 15 to move backward, causing the sliding blocks 14 to slide relative to the slide groove 13. This allows the three wedges 11 and the three positioning posts 16 to move synchronously away from direction A, separating the positioning posts 16 from the positioning groove 8, thus loosening the lens 7 and facilitating disassembly.

[0023] The positioning bolt 4 is threadedly connected to the movable sleeve 3, and the outer side of the lens bracket 2 is provided with a connecting groove 12 that matches the positioning bolt 4. When the positioning post 16 is fully connected to the positioning groove 8, the movable sleeve 3 cannot move forward any further. Then, rotate the positioning bolt 4 to connect it with the connecting groove 12 to lock and fix the movable sleeve 3. The operation is simple and convenient, and effectively prevents the positioning post 16 from becoming loose.

[0024] The lens holder 2 has a retaining ring 9 inside, and a rubber pad 10 is connected to the side of the retaining ring 9. The rubber pad 10 has a ring structure, which improves the sealing between the lens 7 and the lens holder 2.

[0025] Multiple limiting blocks 6 are connected to the outer side of the lens 7. These limiting blocks 6 match the limiting grooves 5 located at the end of the lens holder 2. There are three limiting blocks 6, with an included angle of 120° between adjacent blocks, and each limiting block 6 is aligned with its corresponding positioning groove 8. During installation, the limiting blocks 6 are inserted into the positioning grooves 8, and the lens 7 is moved, achieving initial positioning of the lens 7 and facilitating subsequent connection between the positioning post 16 and the positioning groove 8. The ends of the limiting blocks 6 are rounded, as are the ends of the limiting grooves 5, making it easier for the limiting blocks 6 to be inserted into the limiting grooves 5.

[0026] Working principle: When installing lens 7, insert lens 7 into lens bracket 2, and align limit block 6 with limit groove 5. Push lens 7 to move, so that limit block 6 connects with limit groove 5, achieving initial limiting of lens 7. Push moving sleeve 3 forward, simultaneously driving three pushing blocks 15 and three sliding blocks 14 to move, so that sliding block 14 slides relative to sliding groove 13, driving wedge block 11 and positioning post 16 to move synchronously towards direction A. Until positioning post 16 is pressed against positioning groove 8, moving sleeve 3 stops moving, thus locking and fixing lens 7. With the use of rubber pad 10, the stability and tightness of the connection between lens 7 and lens bracket 2 are improved. The operation is simple, convenient and efficient. Finally, rotate positioning bolt 4 to connect with connecting groove 12, thus locking and fixing moving sleeve 3. When lens 7 needs to be disassembled, loosen the positioning bolt 4 to release the movable sleeve 3, then pull the movable sleeve 3 backward, which simultaneously drives the three pushing blocks 15 and the three sliding blocks 14 backward, so that the three wedge blocks 11 and the three positioning pins 16 move synchronously away from A. The positioning pins 16 separate from the positioning groove 8, thereby releasing lens 7. Then pull lens 7 to separate from lens bracket 2 to achieve the purpose of rapid unloading.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
