Description

Technical Field

[0001] This utility model relates to the field of automotive lamp lens technology, specifically to an anti-reflective coated automotive lamp lens. Background Technology

[0002] In the existing technology, LED lighting sources are small in size, have high brightness and long lifespan, so they are widely used in various fields. Existing LED lighting requires a lens to distribute the light emitted by the light source, thereby reducing residual light. In addition, glass is often used as a lens material because of its high light transmittance.

[0003] Application number CN202420423406.X discloses a high-gloss mirror LED vehicle headlight lens. This utility model sets up a lamp cover with a rotatable movable seat inside. A reflector cup is set at one end of the lamp cover, and an LED bulb is set inside the reflector cup. The light emitted by the LED bulb passes through a convex lens and is focused at a point. When the position of the convex lens changes, the focal point of the light changes accordingly. Thus, the focal point position can be changed with only one LED bulb, so as to achieve the effect of changing the high beam and low beam of the vehicle headlight.

[0004] However, the misalignment of the through slot and the center of the movable seat in this device may cause eccentric force when the lens mount moves, resulting in increased friction or lens tilting, which in turn affects the accuracy of the light path. Furthermore, the lack of heat insulation between the lens and the bulb means that high temperatures can cause lens deformation or coating aging. Therefore, an anti-reflective coated automotive lamp lens is proposed. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides an anti-reflective coated automotive lamp lens.

[0006] The technical solution adopted by this utility model to solve its technical problem is an anti-reflective coated automotive lamp lens, including a light guide cover. The interior of the light guide cover is used for inserting the lamp cover. The lens is installed inside the lamp cover by threads. A second sliding groove is opened on the inner side of the light guide cover. A micro motor is fixedly installed inside the second sliding groove. The output end of the micro motor is fixedly connected to one end of a lead screw. The lead screw is located inside the second sliding groove. A second slider is movably sleeved on the outer side of the lead screw by threads.

[0007] The lampshade has an installation groove and a slot on its outer side. The installation groove and the slot are connected internally. The installation groove is used for one end of the second slider to slide in, and the slot is used for one end of the second slider to be snapped into place. A magnetic block is fixedly installed on one side of the slot, and the magnetic block is magnetically connected to the second slider.

[0008] By adopting the above technical solution, the lampshade displacement is controlled by a micro motor driving a lead screw, and the high and low beam switching is achieved by combining the synergistic optical design of the reflector and lens. The quartz glass heat-insulating lens, the guide rod and the double slider system ensure the movement accuracy, and the magnetic block provides reliable fixation. Users only need to control the micro motor externally to complete the beam pattern adjustment, which is both convenient and durable.

[0009] Specifically, one end of the light guide cover is fixedly connected to one end of the reflector cup, the other end of the reflector cup is fixedly connected to one end of the mounting base, and an LED bulb is installed inside the mounting base by threads.

[0010] By adopting the above technical solution, the reflector cup, as the core component of the optical path, reflects the light emitted by the LED bulb to the front end of the light guide cover through its curved surface design. The mounting base fixes the LED bulb with a threaded structure, facilitating quick replacement or adjustment of the bulb angle. When the lamp cover is moved to adjust the focus, the reflection path of the reflector cup and the focusing effect of the lens work together to ensure accurate light projection, achieving the effect of concentrated strong light at high beams and dispersed anti-glare at low beams.

[0011] Specifically, a quartz glass is threadedly installed inside the light guide cover, and the quartz glass is positioned between the lens and the LED bulb.

[0012] By adopting the above technical solution, quartz glass, as a high-temperature resistant light-transmitting medium, not only allows the light from the LED bulb to pass efficiently through the lens, but also isolates the heat generated by the bulb from being transferred to the lampshade and the outside, thus preventing the lens from deforming or aging due to high temperature.

[0013] Specifically, a first groove is provided on the inner side of the light guide cover, a guide rod is provided inside the first groove, and a first slider is movably sleeved on the outer side of the guide rod.

[0014] By adopting the above technical solution, the first slide and the guide rod constitute an auxiliary track system for the movement of the lampshade. The first slider and the second slider move synchronously, and the two-point fixation improves the stability of the lampshade displacement, avoiding skewing or jamming caused by single-point drive. The rigid support of the guide rod ensures that the lampshade only translates in the set direction and does not produce rotational offset, thereby maintaining the alignment of the optical axis of the lens and the LED bulb.

[0015] Specifically, the mounting groove and the slot are provided in two places opposite each other. The mounting groove is also used for one end of the first slider to slide in, and the slot is also used for one end of the first slider to be snapped into place. The first slider is magnetically connected to the magnetic block.

[0016] By adopting the above technical solution, the mounting slots and slots symmetrically arranged on both sides of the lampshade need to be aligned with the first slider and the second slider at the same time. After insertion, the lampshade is rotated so that the two sliders are respectively locked into the corresponding slots and fixed by double adsorption of magnetic blocks. This symmetrical locking mechanism further enhances the installation stability of the lampshade, ensuring that it remains firm even under frequent adjustment or vibration environments, and avoiding structural loosening caused by uneven force on one side.

[0017] The beneficial effects of this utility model are:

[0018] The anti-reflective coated automotive lamp lens of this invention uses a micro motor to drive a lead screw to control the lamp cover displacement. Combined with the synergistic optical design of the reflector and lens, it achieves high and low beam switching. The quartz glass heat-insulating protective lens, guide rod and double slider system ensure movement accuracy, and magnetic block provides reliable fixation. Users only need to externally control the micro motor to complete the beam pattern adjustment, which is both convenient and durable. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As one embodiment of this utility model, such as Figs. 1-3As shown, the anti-reflective coated automotive lamp lens of this utility model includes a light guide cover 3. The interior of the light guide cover 3 is used for the installation and insertion of a lamp cover 4. A lens 5 is installed inside the lamp cover 4 by means of threads. A second sliding groove 10 is provided on the inner side of the light guide cover 3. A micro motor 13 is fixedly installed inside the second sliding groove 10. The output end of the micro motor 13 is fixedly connected to one end of a lead screw 11. The lead screw 11 is located inside the second sliding groove 10. A second slider 12 is movably sleeved on the outer side of the lead screw 11 by means of threads.

[0026] The lampshade 4 has an installation groove 15 and a slot 16 on its outer side. The installation groove 15 and the slot 16 are internally connected. The installation groove 15 is used for one end of the second slider 12 to slide into, and the slot 16 is used for one end of the second slider 12 to be snapped into place. A magnetic block 14 is fixedly installed on one side of the slot 16, and the magnetic block 14 is magnetically connected to the second slider 12.

[0027] During use, the lampshade 4 needs to be installed by first aligning the mounting slot 15 with the second slider 12 inside the light guide cover 3, pushing it in to the bottom along the slide groove, and then rotating the lampshade 4 so that the second slider 12 slides into the slot 16 and is attracted and fixed by the magnetic block 14. At this time, the micro motor 13 can rotate through the drive screw 11 to drive the second slider 12 to move linearly along the second slide groove 10, thereby pulling the lampshade 4 and lens 5 to move back and forth as a whole. This displacement directly adjusts the distance between the lens 5 and the LED bulb 6 behind it, and achieves the switching between high beam / low beam modes by changing the light focusing state. The magnetic connection of the magnetic block 14 ensures that the slider is stable and does not dislodge during movement.

[0028] It should be noted that the second slide groove 10 serves to limit the movement of the second slider 12, preventing the second slider 12 from rotating with the lead screw 11 and allowing it to move along the axis only within the second slide groove 10.

[0029] This utility model also includes that one end of the light guide cover 3 is fixedly connected to one end of the reflector cup 2, the other end of the reflector cup 2 is fixedly connected to one end of the mounting base 1, and an LED bulb 6 is installed inside the mounting base 1 by means of threads.

[0030] In use, the reflector 2, as the core component of the optical path, reflects the light emitted by the LED bulb 6 to the front end of the light guide cover 3 through its curved surface design. The mounting base 1 fixes the LED bulb 6 with a threaded structure, which facilitates quick replacement or adjustment of the bulb angle. When the lamp cover 4 moves to adjust the focus, the reflection path of the reflector 2 and the focusing effect of the lens 5 work together to ensure accurate light projection and achieve the effect of concentrated strong light when using high beam and dispersed anti-glare when using low beam.

[0031] This utility model also includes a quartz glass 17 installed inside the light guide cover 3 by threads, the quartz glass 17 being disposed between the lens 5 and the LED bulb 6.

[0032] When in use, the quartz glass 17 serves as a high-temperature resistant light-transmitting medium, allowing the light from the LED bulb 6 to efficiently penetrate to the lens 5, while also isolating the heat generated by the bulb from being transferred to the lampshade 4 and the outside, thus preventing the lens 5 from deforming or aging due to high temperatures.

[0033] The present invention also includes a first groove 9 provided on the inner side of the light guide cover 3, a guide rod 8 provided inside the first groove 9, and a first slider 7 movably sleeved on the outer side of the guide rod 8.

[0034] In use, the first slide 9 and the guide rod 8 form an auxiliary track system for the movement of the lampshade 4. The first slider 7 and the second slider 12 move synchronously, and the two-point fixation improves the stability of the displacement of the lampshade 4, avoiding the skewing or jamming caused by single-point drive. The rigid support of the guide rod 8 ensures that the lampshade 4 only moves in the set direction and does not produce rotational offset, thereby maintaining the alignment of the optical axis of the lens 5 and the LED bulb 6.

[0035] The present invention also includes two opposite mounting grooves 15 and slots 16. The mounting groove 15 is also used for one end of the first slider 7 to slide into, and the slot 16 is also used for one end of the first slider 7 to be snapped into place. The first slider 7 is magnetically connected to the magnetic block 14.

[0036] During use, the mounting slots 15 and locking slots 16 symmetrically arranged on both sides of the lampshade 4 must be aligned simultaneously with the first slider 7 and the second slider 12. After insertion, rotate the lampshade 4 so that the two sliders respectively engage with the corresponding locking slots 16 and are secured by double magnetic attraction 14. This symmetrical locking mechanism further enhances the installation stability of the lampshade 4, ensuring that it remains firm even under frequent adjustments or vibration environments, and preventing structural loosening due to uneven force on one side.

[0037] In use, this utility model is first aligned with the mounting groove 15 of the lampshade 4, and then with the first slider 7 and the second slider 12 inside the light guide 3. The first slider 7 and the second slider 12 are then pushed into the mounting groove 15, allowing the lampshade 4 to be inserted into the light guide 3 until the first slider 7 and the second slider 12 are pushed to the deepest point of the mounting groove 15. Then, the lampshade 4 is rotated to allow the first slider 7 and the second slider 12 to slide into the slot 16 and be attracted by the magnetic block 14 in the slot 16. In this way, the lampshade 4 is fixedly connected to the first slider 7 and the second slider 12. The micro motor 13 is started by an external power supply. The micro motor 13 drives the lead screw 11 to rotate. The rotation of the lead screw 11 can drive the second slider 12 to slide in the second slide groove 10. The movement of the second slider 12 can drive the lamp cover 4 to move within the light guide cover 3, thereby adjusting the distance between the lens 5 and the LED bulb 6, and thus adjusting the focal position of the LED bulb 6 to change the effect of high beam and low beam of the car headlight. The high light transmittance of the quartz glass 17 between the LED bulb 6 and the lens 5 can block heat transfer to the lens 5 without affecting the light transmission efficiency.
