Description

Technical Field

[0001] This utility model relates to the field of vehicle light guide structures, and in particular to a light guide structure and a vehicle light. Background Technology

[0002] With the rapid development of optical materials and technologies, light guide structures, as a novel light-guiding lighting technology, have gradually attracted attention. Through the optical properties of the light-guiding material, light guide structures can effectively guide and transmit light generated by a light source, enabling its uniform distribution within a specific area. Compared to traditional automotive headlight designs, light guide structures can provide more delicate light modulation methods, adapting to various complex lighting needs, such as nighttime driving safety and driver safety.

[0003] The light guide structure mainly relies on the combination of the light guide strip and the light source block to carry out the light source generated by the light source block. In existing automotive lighting products, the light source block and the light guide strip often have unstable structural fit at the end connection part, resulting in poor actual light transmission effect. A large amount of light source is not directly shone, which leads to waste and makes it impossible to obtain higher brightness and better light spot uniformity. Utility Model Content

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example: An optical guide structure, such as Figure 1 and Figure 2 As shown, the light source block 1 and light guide strip 2 are movably connected. The light guide strip 2 efficiently conducts and uniformly emits light from the portion of the light source generated by the light source block 1. The light source block 1 includes a light source housing 3 and a light source integrated module 4. The light source integrated module 4 is equipped with LED lamp beads 5. The light source integrated module 4 is movably inserted into the light source housing 3. The installer selects and adapts the light source according to the specific light source model to meet the light intensity requirements. The light source housing 3 has a limiting slot 6 for inserting the light source integrated module 4. The opening of the limiting slot 6 is equipped with a cover plate 7, and the two side walls of the limiting slot 6 are equipped with auxiliary slots 8. The light source integrated module 4 is movably inserted into the auxiliary slots 8. Under normal use, the relative position of the light source integrated module 4 and the light source housing 3 is fixed. The cover plate 7 can be opened only when replacement is needed. At the same time, the light source housing 3 is equipped with a heat dissipation side groove 21, which can effectively dissipate and release heat inside the light source housing 3 to ensure a suitable operating temperature.

[0019] A light guide assembly is provided on the side of the light source housing 3 away from the cover plate 7. The light guide strip 2 and the light source block 1 are connected through the light guide assembly. The light guide assembly can effectively improve the light guiding efficiency and the stability of the light guiding connection. The light guide assembly includes a light guide sleeve 9 that is detachably connected to the light source housing 3 and a light guide limiting ring 10 that is movably connected to the light guide sleeve 9. A light transmission hole 11 is provided on the light source housing 3. The light transmission hole 11 is aligned with the LED lamp bead block 5. A focusing sleeve 14 is provided at the end of the light guide sleeve 9 that is connected to the light source housing 3. The focusing sleeve 14 extends into the light transmission hole 11 and is fastened to the LED lamp bead block 5. This allows the light emitted by the LED lamp bead block 5 to directly enter the focusing sleeve 14 part of the light transmission hole 11, reducing light source waste and improving the efficiency of light guiding transmission, while maintaining the perpendicularity between the incident light source and the end of the light guide strip. Since the diameter of the light guide strip 2 varies, the light source housing 3 located on both sides of the light-transmitting hole 11 is also provided with a threaded locking groove 12, and the light guide sleeve 9 is provided with a locking thread section 13 that cooperates with the threaded locking groove 12. This makes it convenient for staff to select and install according to different specifications during actual use, so as to meet the specification adaptation of the light source housing 3.

[0020] The light guide limiting ring 10 and the light guide sleeve 9 are rotatably sleeved together. The end of the light guide limiting ring 10 furthest from its rotatable connection with the light guide sleeve 9 is provided with a guide strip insertion hole 15. The light guide strip 2 is inserted into the guide strip insertion hole 15. A protective washer 20 is provided at the opening of the guide strip insertion hole 15, enabling smooth and stable insertion and removal of the light guide strip 2. The rotatable design of the light guide limiting ring 10 and the light guide sleeve 9 ensures that installers can flexibly rotate and adjust them during actual use, reducing the phenomenon where the fixed fit between the light guide strip 2 and the light source block 1 prevents flexible adjustment. Furthermore, since the light guide strip 2 is mostly flexible, the rotatable structure effectively eliminates external resistance caused by the torsional deformation of the light guide strip 2 after prolonged use, preventing direct impact on the light guide and affecting the light incident angle.

[0021] To improve the relative stability of the assembly state of the light guide strip 2, a guide strip limiting component is provided inside the light guide limiting ring 10. The operation of the guide strip limiting component is used to achieve relative limiting of the preset installation position of the light guide strip 2. The guide strip limiting component includes multiple pairs of spring clips 16 located at one side of the guide strip insertion hole 15 inside the light guide limiting ring 10, and multiple limiting ring blocks 17 arranged along the length direction of the light guide limiting ring 10. The multiple pairs of spring clips 16 are arranged circumferentially along the opening of the guide strip insertion hole 15, which can elastically clamp the inserted light guide strip 2. After the end of the light guide strip 2 is inserted, it is finally sleeved in the focusing sleeve 14. The focusing sleeve 14 is rotatably connected to the end of the light guide block 9, which further improves the stability of the calibration incident state. That is, when the light guide strip 2 is twisted, the focusing sleeve 14 rotates synchronously. The inner wall of the light guide block 9 is provided with an anti-slip protective pad to reduce the phenomenon of relative sliding and always maintain the direct position of the end of the light guide strip 2 and the LED lamp bead block 5. During the insertion and installation of the light guide strip, the spring clips 16 arranged in pairs on the side are squeezed. A correction groove 18 corresponding to the spring clips 16 is provided on the limiting ring block 17. The correction groove 18 can limit the angle at which multiple pairs of elastic clips open to both sides, always maintaining tight contact with the side of the light guide strip 2. Simultaneously, a winding portion 19 is provided at the end of the spring clips 16. The winding portion 19 improves the elasticity of the spring clips 16 themselves, reduces potential frictional damage to the light guide strip 2, and also helps limit the movement of the light guide strip 2 away from the light guide strip insertion hole 15. Once the light guide strip 2 shows a tendency to slide out of the hole without manual operation, the winding portion 19 is stretched. Under its own elastic recovery potential energy, it can generate a reaction force relative to the sliding of the light guide strip 2, thereby ensuring the fixation of the relative position of the light guide strip 2 and meeting reliable light transmission performance.

[0022] In another aspect, this utility model provides a vehicle lamp including the aforementioned light guide structure. The specific structure and technical effects of this light guide structure have been described in detail above, and therefore will not be repeated here. Of course, the vehicle lamp may include other optical elements besides the light guide structure, and this application does not limit this. The vehicle lamp provided by this application, by employing a light guide structure with a light guide component, can improve the problem in the prior art where unstable connection and fit at the light-incident end of the light guide structure leads to low light guide efficiency and affects the uniform brightness of the light after illumination, thereby improving the operational stability and reliability of the light guide structure.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
