Description

Technical Field

[0001] This utility model belongs to the field of lens module technology, and specifically relates to a lens module, automotive lighting fixtures, and vehicles. Background Technology

[0002] In the current field of automotive headlight lens module design, the connection technology between the lens and the support frame is receiving increasing attention. For a long time, screws and clips have been the mainstream connection methods between the lens and the support frame, playing a key role in the stability of the headlight structure.

[0003] However, with the deepening trend of lightweight and compact automotive design, adjusting the strength of the clips has become a pressing challenge. On the one hand, to meet the miniaturization requirements of headlights, the clip strength needs to be appropriately weakened to balance clip strength and assembly convenience, reducing the encroachment on the space of other components. On the other hand, traditional optimization methods, such as increasing the clip deformation length or reducing the fastening amount, have encountered numerous difficulties in practical applications. Due to the extremely limited space inside headlights and the inherent limitations of mold manufacturing processes, increasing the clip deformation length has reached a bottleneck and is difficult to sustain. While reducing the fastening amount can instantly reduce strength, it significantly compromises the lens module's fixing effect, greatly increasing the risk of lens detachment and directly threatening the reliability and safety of the headlights. Faced with this thorny contradiction, the industry urgently needs an innovative clip design that breaks through traditional thinking to cleverly balance space utilization and fixing effect, opening up new paths for the upgrading of headlight technology.

[0004] Therefore, how to optimize the buckle design within a limited space to ensure the stable fixation of the lens module is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] The core of this utility model is to provide a lens module, a vehicle lamp, and a vehicle, which optimizes the buckle design within a limited space to ensure the stable fixation of the lens module.

[0040] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] For details, please refer to Figures 1-5 The present invention provides a vehicle lamp fixture, including a lens 100 and a support frame 200.

[0042] The first end of the lens 100 has a protrusion 110 on its outer edge. The first end of the support frame 200 is sleeved on the outside of the first end of the lens 100, and the second end of the lens 100 is exposed on the outside of the support frame 200.

[0043] A U-shaped through groove 231 is opened on the side of the first end of the support frame 200 to form a first fastening element 210. The first fastening element 210 is a cantilever structure. The end face of the first end of the support frame 200 is fastened inward to form a second fastening element 220.

[0044] The first fastening element 210 and the second fastening element 220 form a fastening position for engaging the protrusion 110, thereby fixing the lens 100 to the support frame 200.

[0045] This solution provides a lens module including a lens 100 and a support frame 200. The outer edge of the first end of the lens 100 has a protrusion 110 for engaging with the support frame 200 to ensure secure installation. The second end of the lens 100 protrudes from the outside of the support frame 200 for easy compatibility with other optical systems. A U-shaped slot 231 is formed on the side of the first end of the support frame 200, creating a cantilevered first fastening element 210. Simultaneously, the end face of the first end of the support frame 200 is designed with an inward-clipping structure, forming a second fastening element 220. When the lens 100 is inserted into the support frame 200, the protrusion 110 is clamped by the first and second fastening elements 210 and 220, forming a snap-fit ​​position and securing the lens 100 firmly. The installation process is simple and efficient; simply inserting the lens 100 into the support frame 200 achieves a quick and tight connection without the need for additional screws. This solution aims to resolve the contradiction between the snap-fit ​​strength and mold space limitations in traditional automotive headlight lens module connections.

[0046] The above design avoids the problems of lens detachment caused by insufficient length and inadequate locking in traditional lens module snap-fit ​​fixing methods due to space constraints. By utilizing the sidewall of the support frame 200 to form a first locking element 210 and a second locking element 220 in a flexible cantilever shape, the snap-fit ​​design is optimized within a limited space, ensuring stable fixing of the lens module.

[0047] In a specific embodiment, the snapping surfaces of the first snapping element 210 and the protrusion 110 are inclined surfaces, and the snapping position forms an opening that gradually expands from the inside to the outside, so that the protrusion 110 of the lens 100 can be smoothly inserted into the snapping position.

[0048] To improve structural strength, the end of the first fastening element 210 that engages with the protrusion 110 is thickened, such as... Figure 2 As shown, a thickened portion 211 is formed, the thickness of which is greater than that of the other end of the first fastening element 210. In particular, during the assembly process, when the lens 100 is inserted into the support frame 200, the thickness of the thickened portion 211 is sufficient to support the bottom of the protrusion 110 and prevent the protrusion 110 from sliding further into the bottom of the support frame 200.

[0049] In a specific embodiment, a buckle weakening groove 232 is provided on the end face of the first end of the support frame 200. By partially slotting near the second fastening element 220 of the support frame 200, the overall snap-fit ​​position is weakened, thereby solving the problem of excessive buckle strength.

[0050] Furthermore, the latching weakening groove 232 is V-shaped. The lens 100 is easily installed into the designed position through the weakened latching structure and is very difficult to detach.

[0051] To avoid affecting the stability of the buckle, the buckle weakening groove 232 and the U-shaped through groove 231 are staggered.

[0052] In a specific embodiment, the number of snap-fit ​​weakening grooves 232 can be designed to be multiple, and the number of U-shaped through grooves 231 can also be designed to be multiple. The multiple snap-fit ​​weakening grooves 232 and the multiple U-shaped through grooves 231 are symmetrically arranged on the support frame 200 to achieve overall force balance.

[0053] Based on the above specific embodiment, the lens 100 is hemispherical, with its first end being the bottom end and its second end being a spherical end. The support frame 200 has a cylindrical structure. Specifically, the lens 100 is hemispherical with a flat bottom end and an exposed spherical end. The support frame 200 is cylindrical with snap-fit ​​positions on its side walls. The bottom end of the lens 100 is inserted into the support frame 200, and the protruding outer edge of the lens 100 engages with the snap-fit ​​positions of the support frame 200 to achieve a stable connection. This design ensures both the optical function of the lens and facilitates installation and fixation.

[0055] Obviously, headlights that include the aforementioned lens modules have the same beneficial effects, which will not be elaborated upon here.
