Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, specifically a dynamic automotive interactive light. Background Technology

[0002] With the development of automotive intelligence, the function of vehicle lights has gradually expanded from basic lighting to intelligent media with information interaction capabilities. Dynamic automotive interactive lights achieve functions such as welcoming, turning warning, fault indication and road condition feedback through specific light effects. They are increasingly widely used in new energy vehicles and high-end models. Current dynamic optical prototypes usually use microstructure light guide elements in conjunction with control units to achieve dynamic light effect output. Some products can already support multi-scene switching and preliminary linkage with the vehicle system.

[0003] However, existing dynamic interactive lights still have limitations in response speed and light effect control precision in practical applications. Their microstructure design and control algorithms mostly adopt a separate development mode, which makes it easy for delays or discontinuities to occur during light effect switching. At the same time, in terms of multi-scenario adaptation, the existing solutions are not flexible enough in their recognition and response logic for vehicle signals, making it difficult to achieve fast, accurate and uniform dynamic light effect output under different driving conditions, thus limiting the smoothness and safety of the interactive experience. Utility Model Content

[0004] This invention provides a dynamic automotive interactive light that addresses the shortcomings of existing technologies, such as sluggish light effect switching response, rigid scene adaptation, and insufficient uniformity of light distribution. By reconstructing the synergistic relationship between the optical transmission path and the physical driving structure, it achieves millisecond-level light shape transformation, multi-condition adaptive output, and uniform brightness control across the entire range.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A dynamic automotive interactive light comprises four parts: a substrate, a light guide assembly, an actuation mechanism, and a signal interface. The substrate is a rectangular aluminum alloy frame with a stepped mounting groove on its front side and a heat dissipation fin array on its back side. Bolt through holes are provided at the four corners of the substrate for vehicle mounting. The light guide assembly consists of a main light conductor and an auxiliary light conductor. The main light conductor is a wedge-shaped polycarbonate block, with its incident surface attached to the LED light source array. Its exit surface is etched with an asymmetric microprism group, and the prism tilt angle varies gradient along the light path direction. The auxiliary light conductor is an annular silicone strip covering the outer edge of the main light conductor, with an embedded fluorescent particle layer. Its cross-section has a semi-circular convex structure. The actuation mechanism includes a push rod assembly, a slide rail bracket, and an elastic reset component. The push rod assembly consists of three carbon fiber rods arranged in parallel. The front end of each push rod is connected to a miniature permanent magnet, and the rear end is hinged to the slider of the slide rail bracket. The slide rail bracket is a double-rail aluminum alloy component, fixed to the back of the substrate, and its track direction is parallel to the long axis of the main optical conductor. The elastic reset component is a nickel-titanium alloy wire, with one end anchored to the edge post of the substrate and the other end hooked to the through hole in the middle of the push rod. The signal interface is a nine-pin gold-plated plug, encapsulated in a waterproof cavity on the side of the substrate. Each pin corresponds to the power input, ground wire, steering signal, braking signal, fault code, and three reserved channels, respectively.

[0006] The asymmetric microprism group of the main photoconductor is divided into functional regions: the prism tilt angle in the near-light source region is 15 degrees, the tilt angle in the middle region is 28 degrees, and the tilt angle in the far-end region is 42 degrees. The spacing between adjacent prisms gradually changes from 0.8 mm to 1.5 mm. The fluorescent particle layer of the auxiliary photoconductor has a thickness of 0.3 mm, and the particle size is distributed in the range of 5 micrometers to 12 micrometers. Its semi-circular protrusion has a longitudinal groove on its top, with a depth of 0.2 mm and a width of 0.5 mm. The groove is filled with transparent epoxy resin. The length of the three carbon fiber rods in the push rod assembly is... The dimensions are 80 mm, 85 mm, and 90 mm, corresponding to the control of the left turn light zone, right turn light zone, and warning light zone. The permanent magnet at the front end of each push rod is 5 mm in diameter and 2 mm thick, with the magnetic pole direction perpendicular to the push rod axis. The track spacing of the slide rail bracket is 10 mm. The bottom of the slider is equipped with a bronze bushing, and the inner wall of the bushing is machined with a spiral oil groove. The oil groove is pre-filled with molybdenum disulfide grease. The nickel-titanium alloy wire of the elastic reset component has a diameter of 0.5 mm and a pre-stretch amount of 8% of the original length. Its anchor point is located at the midpoint of the short side of the substrate.

[0007] The substrate has three levels of stepped mounting grooves: the first level is 3 mm deep to accommodate the LED light source array, the second level is 7 mm deep to position the main light conductor, and the third level is 12 mm deep to embed the auxiliary light conductor. The heat dissipation fin array consists of 45 wavy fins, each 8 mm high, with a spacing of 1.2 mm between adjacent fins. The fin surfaces are anodized to form a matte black layer. In the nine-pin connector of the signal interface, the first pin is for a +12V power supply, the second pin is ground, the third pin receives the left turn pulse, the fourth pin receives the right turn pulse, the fifth pin receives the braking high level, the sixth pin receives the fault code serial data, and the seventh to ninth pins are reserved for extended functions. The LED light source array contains 16 high-brightness white light chips arranged in a 4x4 matrix, with each chip having a power of 0.5 watts. The light-emitting surface is covered with a quartz glass lens with a curvature radius of 3.5 mm.

[0008] The actuator push rod assembly and the light guide assembly are mechanically linked: when the slider moves along the slide rail, the push rod pushes the main light guide to produce a small displacement, ranging from 0.5 mm to 2.5 mm. This displacement changes the angle of the microprism group relative to the LED light source, thereby adjusting the shape of the emitted light spot. The elastic reset component maintains the push rod's initial position when there is no electromagnetic force. When the permanent magnet is driven by the external coil magnetic field, the push rod overcomes the elastic force and produces displacement. The slide rail bracket has a limit stop at the end, which is made of polyoxymethylene and has a copper buffer pad embedded in its contact surface, limiting the maximum stroke of the push rod to three mm. The longitudinal groove of the auxiliary light guide deforms during the push rod displacement, and the groove cross-section changes from rectangular to trapezoidal. This deformation adjusts the excitation efficiency of the fluorescent particles and achieves brightness compensation in the auxiliary light area.

[0009] A temperature sensor is integrated on the back of the substrate. The sensor probe is attached to the main photoconductor mounting base, and its signal line is connected to the eighth pin of the signal interface. The temperature sensor is an NTC thermistor, and its resistance decreases exponentially with increasing temperature. It is used to monitor the operating temperature rise of the photoconductor. A light-guiding gel layer is set between the incident surface of the main photoconductor and the LED light source array. The gel layer is 0.1 mm thick and has a refractive index of 1.54 to eliminate the loss of total internal reflection at the interface. The outer surface of the auxiliary photoconductor is covered with a hydrophobic coating with a thickness of 5 micrometers and a contact angle greater than 110 degrees to prevent water vapor condensation from affecting the light transmittance. The waterproof cavity of the signal interface adopts a double-sealed structure. The inner layer is a fluororubber O-ring, and the outer layer is silicone injection molding, achieving a protection level of IP67.

[0010] The bronze bushing of the slide rail bracket has a semi-circular spiral oil groove with a pitch of 5 mm and a depth of 0.3 mm. The lubricating oil forms a dynamic oil film during the reciprocating motion of the push rod. The air gap between the permanent magnet at the front end of the push rod and the external drive coil is 0.8 mm. The coil winding uses enameled copper wire with 300 turns and a wire diameter of 0.2 mm. The nickel-titanium alloy wire of the elastic reset component maintains a stable elastic modulus in the range of -40°C to 85°C. Its phase transition temperature is set at 90°C to avoid failure under high-temperature conditions. The surface of the microprism group of the main optical conductor is coated with an anti-reflection film. The film material is an alternating stack of silicon dioxide and titanium dioxide with a total thickness of 230 nanometers, which increases the transmittance of visible light by 12%.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: Through the coupling design of the gradient microprism group of the main light conductor and the mechanical displacement of the push rod, the light spot shape switching time is shortened to 80 milliseconds, which is 25% better than the traditional solution. Moreover, the light shape transition is continuous without abrupt changes. The correlation mechanism between the deformation of the auxiliary light conductor groove and the fluorescence excitation efficiency compensates for the edge brightness attenuation caused by the displacement of the main light conductor. The uniformity of illumination across the entire area reaches 93.5%. The three sets of independent push rods, combined with the asymmetric permanent magnet layout, support the physical light shape reconstruction of eight scenarios: left turn, right turn, braking, fault, welcome, reversing, rain and fog, and pedestrian warning. There is no need to rely on electronic dimming devices. The combination of the nickel-titanium alloy elastic reset component and the bronze bushing oil groove ensures that the push rod positioning accuracy deviation is less than 0.05 mm after 100,000 mechanical cycles. The double-sealed signal interface and the hydrophobic coating auxiliary light conductor meet the requirements of reliable operation in the entire temperature range from -40 degrees Celsius to 85 degrees Celsius. The salt spray test shows no corrosion failure after 500 hours. Attached Figure Description

[0014] 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.

[0015] Please see Figures 1 to 3 One embodiment of this utility model is a dynamic automotive interactive light, the structure of which includes a substrate 1, a main light conductor 2, an auxiliary light conductor 3, a push rod group 4, a slide rail bracket 5, an elastic reset component 6, an LED light source array 7, a heat sink array 8, a signal interface 9, and a temperature sensor 10. The components cooperate with each other through mechanical positioning, physical linkage, and optical transmission path to achieve rapid switching of light shape, uniform brightness distribution, and multi-condition adaptive output.

[0016] The substrate 1 is a rectangular aluminum alloy component with a three-tiered stepped mounting groove on the front and forty-five wavy heat dissipation fins on the back. Each fin is eight millimeters high, and the spacing between adjacent fins is 1.2 millimeters. The surface is anodized to form a matte black layer. The four corners of the substrate 1 have bolt through holes for fixing to the vehicle body sheet metal. The first-level mounting groove is three millimeters deep and is used to embed the LED light source array 7; the second-level mounting groove is seven millimeters deep and is used to position the main light conductor 2; the third-level mounting groove is twelve millimeters deep and is used to accommodate the auxiliary light conductor 3. A column is provided at the midpoint of the short side of the substrate 1 for anchoring one end of the elastic reset component 6.

[0017] The LED light source array 7 consists of sixteen high-brightness white light chips arranged in a four-by-four matrix in the primary mounting slot. Each chip has a power of 0.5 watts. The light-emitting surface is covered with a quartz glass lens with a radius of curvature of 3.5 mm. A light-guiding gel layer is filled between the LED light source array 7 and the incident surface of the main light conductor 2. The gel layer has a thickness of 0.1 mm and a refractive index of 1.54, which eliminates the loss of total internal reflection at the interface and improves the light energy coupling efficiency.

[0018] The main light conductor 2 is a wedge-shaped polycarbonate block. Its incident surface is attached to the LED light source array 7, and its exit surface is etched with an asymmetric microprism group. The microprism group is divided into functional areas: the prism tilt angle in the near light source area is 15 degrees, the tilt angle in the middle section area is 28 degrees, and the tilt angle in the far end area is 42 degrees. The spacing between adjacent prisms gradually changes from 0.8 mm to 1.5 mm. The surface of the microprism group is coated with an anti-reflection film. The film layer is composed of alternating stacks of silicon dioxide and titanium dioxide, with a total thickness of 230 nanometers. The transmittance in the visible light band is increased by 12%. The main light conductor 2 is embedded in the secondary mounting slot, and its long axis is parallel to the track direction of the slide rail bracket 5.

[0019] The auxiliary photoconductor 3 is a ring-shaped silicone strip that covers the outer edge of the main photoconductor 2. It has a semi-circular convex structure in cross-section and a longitudinal groove on the top. The groove is 0.2 mm deep and 0.5 mm wide. The groove is filled with transparent epoxy resin. The auxiliary photoconductor 3 has an embedded fluorescent particle layer with a particle size distribution in the range of 5 to 12 micrometers and a layer thickness of 0.3 mm. The outer surface of the auxiliary photoconductor 3 is coated with a hydrophobic coating with a thickness of 5 micrometers and a contact angle greater than 110 degrees to prevent water vapor condensation from affecting the light transmittance. The auxiliary photoconductor 3 is embedded in a three-level mounting groove. Its ring structure matches the contour of the main photoconductor 2 to form a continuous optical boundary.

[0020] The push rod assembly 4 consists of three carbon fiber rods arranged side by side, with lengths of 80 mm, 85 mm, and 90 mm respectively, corresponding to the control of the left turn light zone, right turn light zone, and warning light zone. Each push rod has a miniature permanent magnet fixed at its front end. The permanent magnet has a diameter of 5 mm and a thickness of 2 mm, with the magnetic pole direction perpendicular to the push rod axis. The rear end of the push rod is hinged to the slider of the slide rail bracket 5. The bottom of the slider is equipped with a bronze bushing. The inner wall of the bushing is machined with a spiral oil groove with a pitch of 5 mm and a depth of 0.3 mm. It is pre-filled with molybdenum disulfide grease to form a dynamic oil film to reduce frictional resistance. The middle of the push rod has a through hole for hooking the elastic reset component 6.

[0021] The slide rail bracket 5 is a double-rail aluminum alloy component, fixed to the back of the substrate 1. The track spacing is 10 mm, and the track direction is parallel to the long axis of the main light conductor 2. The end of the slide rail bracket 5 is provided with a limiting block. The block is made of polyoxymethylene, and the contact surface is inlaid with a copper buffer pad to limit the maximum stroke of the push rod to 3 mm. When the slider slides along the track, it drives the push rod group 4 to move back and forth. The front end of the push rod pushes the main light conductor 2 to produce a small displacement, with the displacement ranging from 0.5 mm to 2.5 mm. This changes the angle of the microprism group relative to the LED light source, thereby adjusting the shape of the emitted light spot.

[0022] The elastic reset component 6 is a nickel-titanium alloy wire with a diameter of 0.5 mm. One end is anchored to the column at the midpoint of the short side of the substrate 1, and the other end is hooked to the through hole in the middle of the push rod assembly 4. The pre-stretch of the elastic reset component 6 is 8% of the original length. It maintains the initial position of the push rod when there is no external magnetic field. The phase transition temperature of the nickel-titanium alloy wire is set to 90 degrees Celsius. It maintains a stable elastic modulus in the range of -40 degrees Celsius to 85 degrees Celsius to ensure that the reset function does not fail under high temperature conditions.

[0023] Signal interface 9 is a nine-pin gold-plated connector, encapsulated in a waterproof cavity on the side of substrate 1. The cavity adopts a double-sealed structure, with an inner layer of fluororubber O-rings and an outer layer of silicone injection molding, achieving an IP67 protection rating. The first pin is for a positive 12V power input, the second pin is grounded, the third pin receives the left turn pulse signal, the fourth pin receives the right turn pulse signal, the fifth pin receives the brake high-level signal, the sixth pin receives the fault code serial data, and the seventh to ninth pins are reserved channels for extended functions. Each pin of signal interface 9 is electrically connected to the LED light source array 7, the external drive coil, and the temperature sensor 10 via a flexible circuit board.

[0024] Temperature sensor 10 is an NTC thermistor. The probe is in close contact with the main photoconductor 2 mounting base. The signal line is connected to the eighth pin of the signal interface 9. The resistance of temperature sensor 10 decreases exponentially with the increase of temperature. It monitors the working temperature rise of the photoconductor in real time. When the temperature exceeds 75 degrees Celsius, it outputs a power reduction command through the eighth pin to reduce the LED driving current by 20% to avoid thermal damage.

[0025] The external drive coil is not marked with an independent number in the attached drawings. Its winding uses enameled copper wire with 300 turns and a wire diameter of 0.2 mm. The installation position corresponds to the permanent magnet at the front end of the push rod assembly 4. The air gap is 0.8 mm. When the coil is energized, it generates a magnetic field, which attracts the permanent magnet and drives the push rod to move, overcoming the tension of the elastic reset piece 6 and realizing the displacement control of the main optical conductor 2.

[0026] When the vehicle's left turn signal is triggered, the third pin of signal interface 9 receives a pulse current, which drives the left coil to generate a magnetic field, attracting the corresponding permanent magnet to move the push rod. This causes the microprism angle in the left area of ​​the main photoconductor 2 to deflect by seven degrees. At the same time, the longitudinal groove in the left section of the auxiliary photoconductor 3 is squeezed and deformed, changing the groove cross-section from rectangular to trapezoidal. This increases the excitation efficiency of the fluorescent particles by 15%, forming a left arrow light pattern. When the right turn signal is triggered, the fourth pin receives a pulse, and the right coil drives the corresponding push rod to achieve a right arrow light pattern output.

[0027] When the braking signal is activated, the fifth pin inputs a high level, the three sets of coils are synchronously energized, the push rod group 4 moves forward by 1.8 mm, the microprism group of the main photoconductor 2 enters a wide-angle scattering state, the auxiliary photoconductor 3 expands its full-area groove, the fluorescence excitation efficiency is evenly improved, and a uniform high-brightness red light is output. The fault code is transmitted serially through the sixth pin, and after being analyzed by the internal decoder, it controls the three sets of push rods to reciprocate in a specific sequence to generate an SOS Morse code light effect for fault indication.

[0028] In welcome mode, the three sets of push rods move alternately according to a preset rhythm. The angle of the microprism of the main light conductor 2 changes periodically, and the groove of the auxiliary light conductor 3 deforms to form a flowing light strip effect. When the reversing mode is activated, the push rod group 4 moves backward by 0.8 mm, the tilt angle of the microprism decreases, and the beam concentrates on the ground area. In rain and fog mode, the displacement of the push rod is controlled at 1.2 mm, the scattering angle of the microprism is moderate, and both penetration and illumination uniformity are taken into account. In pedestrian warning mode, the push rod vibrates at a high frequency and small amplitude, and the edge of the light spot flashes dynamically to enhance visual recognition.

[0029] During the displacement of the main light conductor 2, the change in the angle of its exit surface microprism group causes the light path refraction direction to shift, and the shape of the light spot changes accordingly. The longitudinal groove of the auxiliary light conductor 3 undergoes elastic deformation under the squeezing or stretching action of the push rod. The change in the geometric parameters of the groove cross section adjusts the excited area and optical path of the fluorescent particles, compensates for the edge brightness attenuation caused by the displacement of the main light conductor 2, and keeps the uniformity of the global illuminance above 93.5%.

[0030] The spiral oil groove inside the bronze bushing of the slide rail bracket 5 continuously releases grease during the reciprocating motion of the push rod, forming a stable oil film, reducing sliding friction, and ensuring that the positioning accuracy deviation of the push rod is less than 0.05 mm after 100,000 mechanical cycles. The elastic reset component 6, made of nickel-titanium alloy wire, does not undergo plastic deformation during repeated stretching and compression, and the reset force is stable, ensuring the consistency of optical shape switching.

[0031] The heat dissipation fin array 8 on the back of the substrate 1 accelerates heat dissipation by increasing the surface area. Together with the thermal grease layer, it conducts the heat generated by the LED light source array 7 to the metal structure of the vehicle body, maintaining the operating temperature within a safe range. The temperature sensor 10 provides real-time feedback of temperature data. The system dynamically adjusts the LED driving current according to the temperature rise trend to prevent overheating from causing material aging or optical performance degradation.

[0032] The signal interface 9 features a waterproof cavity with a double-sealed structure that effectively isolates external moisture and salt spray corrosion. It showed no corrosion failure during a 500-hour salt spray test. The auxiliary photoconductor 3 has a hydrophobic coating that inhibits condensation in low-temperature and high-humidity environments, maintaining a clear optical interface. The entire device operates normally within an ambient temperature range of -40°C to 85°C, meeting the all-weather operation requirements of automotive electronic equipment.

[0033] The three carbon fiber rods of the push rod assembly 4 are independently controlled, each corresponding to a different functional area. Through combined displacement, eight preset light patterns can be output. Physical light pattern reconstruction can be completed without relying on electronic dimming devices. The gradient microprism group of the main light conductor 2 is coupled with the mechanical displacement of the push rod, which shortens the light spot shape switching time to eighty milliseconds. The light pattern transition is continuous and stepless, improving dynamic response performance.

[0034] During device assembly, first place the LED light source array 7 into the primary mounting slot of the substrate 1, apply light guide gel, and then press the main light conductor 2 into the secondary mounting slot. Next, wrap the auxiliary light conductor 3 around the outer edge of the main light conductor 2 and embed it into the tertiary mounting slot. The slide rail bracket 5 is fixed to the back of the substrate 1 with screws. The rear end of the push rod assembly 4 is hinged to the slider, the front end of the permanent magnet is aligned with the external coil mounting position, the middle through hole is hooked to the elastic reset piece 6, the signal interface 9 is welded to the flexible circuit board and then installed into the waterproof cavity. The silicone potting completes the sealing. The temperature sensor 10 probe is bonded to the mounting base of the main light conductor 2, and the lead wire is connected to the eighth pin of the signal interface 9. Finally, the limit block and protective cover are installed to complete the assembly of the whole machine.

[0035] During maintenance, fault codes can be read through the sixth pin of signal interface 9 to determine the fault type, such as push rod jamming, coil open circuit, or abnormal temperature. When replacing parts, remove the fixing bolts of the base plate 1, disconnect the plug of signal interface 9, take out the slide rail bracket 5 and push rod assembly 4, replace the damaged components, and reassemble and calibrate to restore the function.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
